摘要:OBJECTIVE To provide ideas for solving the dispute of trans-provincial distribution of traditional Chinese medicine (TCM) decoction pieces in accordance with provincial standards (hereinafter referred to as “local TCM decoction pieces”). METHODS Through simulation scenarios and collecting actual cases ,the conditions of trans-provincial distribution of local TCM decoction pieces were listed ;the official websites were searched or relevant personnel of drug supervision were interviewed;the current situation of trans-provincial distribution supervision of local TCM decoction pieces in China were sorted out. Based on the stakeholder theory ,the benefits and risks of main stakeholders were discussed to put forward relevant suggestions from the perspective of benefit /risk balance. RESULTS & CONCLUSIONS The conditions of trans-provincial distribution of local TCM decoction pieces in China included enterprises in B province produced TCM decoction pieces according to the A provincial standards,sold and used them in A province ;enterprises in B province produced TCM decoction pieces according to the B provincial standards ,sold and used them in A province ;enterprises in B province produced TCM decoction pieces according to the C provincial standards ,sold and used them in A province. At present ,there are no clear relevant provisions of national laws about trans-provincial distribution supervision of local TCM decoction pieces. Local regulatory opinions mainly come from the reply of the official website of drug regulatory department to online consultation ,and only Shandong ,Shanghai,Liaoning and Jiangxi have issued replies or normative documents. Totally 41.9%,38.7% and 32.3% of the provinces respectively allow the trans-provincial distrbution of local TCM decoction pieces in the above 3 conditions;in addition ,32.3%,16.1% and 22.6% provinces have unclear regulatory attitudes towards the 3 conditions. The benefits and risks analysis of relevant stakeholders shows that it is more in line with the scientific regulatory concept of benefit/risk balance to conditionally allow trans-provincial distribution of local TCM decoction pieces ,but the regulatory effect depends on the scientificity of the regulatory strategy. It is suggested that the drug regulatory departments clarify the relationship between the national and local standards for TCM decoction pieces and dingrl375@163.com differentiate the varieties of collection ;clear the regulatory requirements for trans-provincial distribution of local TCM decoction pieces by issuing high-level legal d ocuments;enrich regulatory measures and means ,and gradually adjust the requirements of trans-provincial distribution of local TCM decoction pieces .
摘要:OBJECTIVE To pr ovide theoretic support for Guiyang to scientifically guide the development of drug retail industry and implement national health policies . METHODS The data were collected through statistical yearbook ,data cloud , coordinate acquisition device of Application Programming Interface of Baidu map and so on. The spatial distribution characteristics and accessibility of medical insurance designated retail pharmacies (shorted for “designated pharmacies ”)in Guiyang were analyzed by spatial analysis based on Geographic Information System. The related factors for the distribution of designated pharmacies in Guiyang were analyzed by statistical method. RESULTS The number of designated pharmacies ,designated pharmacies per thousand people and designated pharmacies per 10 km2 in Guiyang increased from 2 018,0.41 and 2.51 in 2020 to 2 500,0.42 and 3.11 in 2021,with growth rates of 23.89%,2.44% and 23.90% respectively. The service area of the designated pharmacies that residents of Guiyang reached within 15 minutes on foot was 10.27% of the total service area of designated pharmacies in Guiyang. The results of correlation analysis showed that the correlation coefficients between the regional gross regional production ,total retail sales of consumer goods ,population,urban per capita disposable income and the number of designated pharmacies in Guiyang were 0.999,0.999,0.977 and 0.992,respectively (all P<0.05). CONCLUSIONS The distribution of designated pharmacies is insufficient in Guiyang ,the development of designated pharmacies in various administrative regions is uneven ,and the layout of pharmacies is significantly affected by economic and demographic factors. It is suggested that the local government should explore the strategy of scientifically and reasonably expanding the coverage of designated pharmacies in urban and rural areas,promote the rational layout of pharmacies with appropriate economic and demographic policies ,and pay attention to improving the service capacity of designated pharmacies ,so as to improve the quality of life of the people and guide the healthy and high-quality development of drug retail industry.

摘要:OBJECTIVE To study the effects of increasing efficacy and decreasing toxicity of ginkgo flavone aglycone (GA) on doxorubicin (DOX)in the treatment of liver cancer. METHODS A tumor bearing model was established by inoculating liver cancer cell H 22 into the right axillary skin of ICR mice. The successfully modeled mice were randomly divided into model control group,DOX group (2.5 mg/kg,once every other day ,via tail vein ),GA group (30 mg/kg,once a day ,gavage)and GA+DOX group(the usage was the same as single drug groups ),with 6 mice in each group. The administration cycle was 15 days. The general growth of mice in each group were observed ,body weight and tumor weight were measured ,and the inhibition rate of tumor was calculated. Jin’s formula was used to evaluate the effect of combined medication (Q). The serum level of alpha-fetal protein(AFP),the pathological changes of tumor tissue ,cell apoptosis and the expression of platelet-endothelial cell adhesion molecule-1(CD31)were detected in each group. The cardiac index,serum levels of B-type natriuretic peptide (BNP)and N-terminal pro-brain natriuretic peptide (NT-pro BNP ),pathological changes of heart and myocardial fibrosis degree were also detected. RESULTS The percentage of body weight change (except for GA group ) and tumor weights of DOX group,GA group and GA + DOX group were all decreased significantly,compared with model control group (P<0.05 or P<0.01),while tumor weight of GA+DOX gro up was significantly lower than DOX group (P<0.01). Inhibitory rates of tumor in 3 administration groups were 54.29%,42.50% and 89.29% respectively,and Q of two-drug combination was 1.21. The tumor tissues of mice in each administration group were necrotic to varying degrees ;the serum level of AFP and the expression of CD31 in tumor tissue were decreased significantly ,compared with model control group (P<0.05 or P<0.01);the percentage of necrosis area of tumor tissue and the positive rate of apoptosis (except for single drug groups )were significantly increased (P<0.05 or P<0.01),while positive rate of apoptosis in GA+DOX group was significantly higher than DOX group (P<0.05). Cardiac index of mice in DOX group was significantly lower than model control group (P<0.01);serum levels of BNP and NT-pro BNP in DOX group and GA+ DOX group were significantly higher than model control group (P<0.05 or P<0.01);pathological changes of heart and the degree of myocardial fibrosis in GA+DOX group were lower than DOX group. CONCLUSIONS GA combined with DOX show synergistic antitumor effect. GA can strengthen the apoptosis promoting effect of DOX ,and can help to reduce the cardiotoxicity of DOX.

摘要:OBJECTIVE To optimize the extraction technology of modified Tabusen- 2(MT-2),and to investigate inhibitory effects of the extract obtained by the optimal technology on osteoclast differentiation. METHODS The index components of MT- 2 process optimization were selected by using network pharmacology. Based on single factor tests ,the extraction technology of MT- 2 was optimized by Box-Behnken design-response surface methodology according to the comprehensive score of contents of above index components ,and then validated. RAW 264.7 cells were induced by receptor activator of nuclear factor-κB ligand(100 ng/mL) to prepare osteoclast differentiation model. Inhibitory effects of MT- 2 extract(18.6,37.2,74.4 ng/mL)obtained by the optimal technology on osteoclast differentiation were investigated. RESULTS The index components screened by network pharmacology included chlorogenic acid ,terpineol diglucoside ,isochlorogenic acid A ,1,5-dicaffeoylquinic acid ,hydroxysafflower yellow A , ginsenoside Rg 1 and ginsenoside Rb 1. The optimal extraction technology of MT- 2 was ethanol volume fraction of 60% ,the solid-liquid ratio of 1 ∶ 14(g/mL),extraction time of 94 min and extraction times of twice. The average comprehensive score obtained by the three validation experiments was 95.50,and the relative error with the predicted value (95.75)was -0.26%. Compared with osteoclastic differentiation model cells ,the cells treated with MT- 2 extract prepared by the optimal technology were mostly mononuclear round cells ,and the number of osteoclasts decreased significantly (P<0.05),its inhibitory effects tended to strengthen with the increase of drug concentration. CONCLUSIONS The optimal extraction technology of MT- 2 is stable and feasible. Obtained extract can inhibit osteoclast differentiation.

摘要:OBJECTIVE To expl ore the mechanism of effe ctive fractions from Xiongma decoction in the treatment of migraine with hyperactivity of liver-yang and blood stasis. METHODS Totally 70 male SD rats were randomly divided into normal group , model group ,positive control group (Flunarizine hydrochloride capsules 0.9 mg/kg),low-dose and high-dose groups of Xiongma decoction effective fractions (ethyl acetate extract 0.87,3.46 g/kg,n-butanol extract 1.80,7.20 g/kg). Except for normal group , rats in other groups were given aconite decoction (2 g/kg),once a day ,for 4 consecutive weeks to establish the hyperactivity model of liver-yang. On the 15th day of modeling ,all administration groups were given corresponding drugs intragastrically at the same time ,once a day ,for 2 consecutive weeks. On the 29th day of modeling ,rats trigeminal ganglion was stimulated to establish the migraine model with hyperactivity of liver-yang and blood stasis ,then the medication was maintained for another time according to the above method. The macroscopic signs and behavior of the rats were observed ;positive expression ,mRNA and protein expression of transient receptor potential vanilloid 1 (TRPV1),calcitonin generelated peptide (CGRP),calcitonin receptor-like receptor (CRLR) and receptor-associated membrane proteins 1 (RAMP1) in trigeminal cervical spinal complex (TCC) were detected by immunohistochemistry ,RT-qPCR and Western blot assay. RESULTS Rats in model group showed macrophysical signs and behaviora l manifestations related to migraine with hyperactivity of liver-yang and blood stasis. Thirty minutes after last administration ,the above conditions of rats in Xiongma decoction effective fraction groups were improved significantly. Compared with normal group , positive expression,mRNA and protein expression of TRPV 1,CGRP, CRLR and RAMP 1 in TCC of rats in the model group were significantly increased (P<0.05). Compared with model zengguirong@hnse.org group, most of above indicators in Xiongma decoction effective fraction groups were significantly decreased (P<0.05). CONCLUSIONS The mechanism of Xiongma decoction in preventing and treating migraine with hyperactivity of liver-yang and blood stasis may be related to inhibit the activity of TRPV1-CGRP/CGRP receptor signaling pathway in TCC.

摘要:OBJECTIVE To evaluate the intervention effect of Caulis sinomenii compatible with prepared Aconiti Lateralis on bone destruction in rheumatoid arthritis (RA)model rats ,and to investigate its mechanism. METHODS Totally 40 SD rats were randomly divided into blank group ,model group ,positive control group (indomethacin 0.013 5 g/kg)and C. sinomenii compatible with prepared Aconiti Lateralis group (C. sinomenii 1.08 g/kg+prepared Aconiti Lateralis 1.35 g/kg)according to body mass ,with 10 rats in each group. Except for the blank group ,all the other groups made RA rat models by injecting type Ⅱ bovine collagen. Rats in each group were given corresponding drugs or distilled water intragastrically. The general information ,body weight ,foot swelling and arthritis index (AI)scores of rats in each group were recorded. After the 30th day of administration ,the changes of ankle bone in rats were detected by small animal CT machine. The levels of inflammatory factors [interleukin- 31(IL-31),IL-25 and IL- 3] and chemokines [receptor activator of nuclear factor κB ligand(RANKL),receptor activator of nuclear factor κB (RANK)and osteoprotegerin (OPG)] in serum were detected by enzyme-linked immunosorbent assay. Pathological indexes of rat ankle joint were observed by HE staining. Immunohistochemical method was used to detect the expression of RANKL ,RANK and OPG in synovial tissue of rat ankle joint. RESULTS Compared with blank group ,the mental state of the model group was weak , the activity decreased significantly ,the hair lost luster ,and the body weight decreased significantly on the 12th to 30th days (P< 0.05 or P<0.01);the swelling degree of the foot was significantly increased and the AI score was significantly increased on the 12th to 30th days(P<0.01);the ankle joint in model group had rough surface ,obvious tissue damage and serious bone erosion ; serum levels of IL- 31,IL-25,IL-3,RANKL and RANK were increased significantly ,while the level of OPG was decreased significantly (P<0.01); the expression of RANKL and RANK in synovium of ankle joint increased significantly , while the expression of OPG decreased significantly (P<0.01). Compared with model group ,the above indexes of administration groups were improved to varying degrees ,and most of the differences were statistically significant (P<0.05 or P<0.01). CONCLUSIONS By inhibiting the RANKL/RANK/OPG signaling pathway ,C. sinomenii compatible with prepared Aconiti Lateralis can inhibit the excessive proliferation of osteoclasts and restore the balance of bone metabolism so as to play a role in protecting bone joints and treating RA.

摘要:OBJECTIVE To explore the effects of irbesartan(Irb)combined with 5-fluorouracil(5-FU)on the proliferation and extracellular signal-regulated kinase (ERK)/peroxidase proliferator-activated receptor γ(PPARγ)signaling pathway of Lewis lung cancer cells. METHODS Lewis lung cancer cells from mice were divided into normal control (NC)group,Irb low-dose (LD)group(1×10-3 mmol/L),Irb high-dose (HD)group(1×10-1 mmol/L),5-FU group (10 μmol/L),Irb LD+ 5-FU group (Irb 1×10-3 mmol/L+5-FU 10 μmol/L)and Irb HD+ 5-FU group (Irb 1×10-1 mmol/L+5-FU 10 μmol/L). MTT method was used to measure the activity of cell proliferation in each group. Plate colony formation experiment was used to determine the number of cell colonies formed in each group ;Western blot method was used to detect the expression levels of proliferating cell nuclear antigen (PCNA),p53,ERK1/2,p-ERK1/2 and PPAR γ protein in each group. RESULTS Compared with the NC group ,the cell proliferation activity ,the number of colonies formed and the protein levels of PCNA ,p-ERK1/2,and PPARγ were significantly reduced in the other five groups ,and the protein level of p 53 was significantly increased (P<0.05);the protein expression of ERK1/2 had no significant difference (P>0.05). The changes of above indexes in Irb LD+ 5-FU group and Irb HD+ 5-FU group were more significant than Irb LD group ,Irb HD group and 5-FU group (P<0.05). CONCLUSIONS Irb combined with 5-FU can inhibit the proliferation of Lewis lung cancer cell ,and the effect is better than that of the two alone. The mechanism may be related to the inhibition of ERK/PPARγ signal pathway.
摘要:OBJECTIVE To determine the conte nts of 4 main components in Rougui renshen granules ,and to establish the fingerprint and to screen differential markers affecting its quality. METHODS HPLC method was employed to determine the contents of ammonium glycyrrhizinate ,glycyrrhizin,cinnamic acid and cinnamaldehyde. HPLC fingerprints of 10 batches of Rougui renshen granules were established simultaneously. Similarity Evaluation System of Chromatographic Fingerprint of TCM (2012 edition)was used to evaluate the similarity and determine the common peak ;SPSS 25.0 and SIMCA 14.1 software were applied for cluster analysis (CA),principal component analysis (PCA)and partial least square-discriminant analysis (OPLS-DA). The differential markers affecting sample quality were screened by using the variable importance in projection (VIP)value> 1 as standard. RESULTS The methodology of content determination met the relevant requirements. The contents of ammonium glycyrrhizinate,glycyrrhizin,cinnamic acid and cinnamaldehyde were 1.808 4-2.770 0,1.137 2-1.481 4,0.076 5-0.091 8 and 0.130 9-0.478 4 mg/g,respectively. A total of 16 common peaks were found in the fingerprints of 10 batches of Rougui renshen granules. Four chromatographic peaks were identified ,i.e. glycyrrhizin (peak 6),cinnamic acid (peak 10),cinnamaldehyde(peak 11)and ammonium glycyrrhizinate (peak 15). The similarities of samples were >0.95. Results of CA showed that 10 batches of samples could be classified into three categories :S3 was grouped into one category ;S1-S2,S4-S5 and S 10 were grouped into one category;S6-S9 were grouped into one category. The results of PCA showed that the cumulative contribution rate of the first three principal components was 91.918%,and the classification results were consistent with CA. The results of OPLS-DA showed that the four peaks with VIP value >1 were peak 11(cinnamaldehyde),peak 15(ammonium glycyrrhizinate ),peak 6(glycyrrhizin) and peak 9. CONCLUSIONS Established methods of content determination and fingerprint are accurate and reproducible ,and can be used for the quality evaluation of Rougui renshen granules. The components as ammonium glycyrrhizinate ,cinnamaldehyde, glycyrrhizin may be differential markers affecting the quality of Rougui renshen granules.

The willingness to pay threshold was 3 times of gross domestic product (GDP)per capita in 2021 [242 928 yuan/QALY(quality-adjusted life year )]. Scenario analysis was used to analyze and compare the two regimens under the scenario of complimentary drug for patients in dual-immunotherapy group. The robustness of the findings was evaluated by one-way sensitivity analysis and probabilistic sensitivity analysis. RESULTS Baseline analysis results showed that total cost of dual-immunotherapy regimen was higher than that of chemotherapy regimen ,and the utility was also better than that of chemotherapy plan ;the incremental cost-effectiveness ratio (ICER)was 417 122.2 yuan/QALY,which was higher than the willingness to pay threshold ;the dual-immunotherapy regimen was not cost-effective compared to the chemotherapy regimen. Under the scenario of complimentary drug ,the cost of dual-immunotherapy was 327 454.5 yuan,ICER was 75 664.1 yuan/QALY,which was lower than the willingness to pay threshold and resulted in a reversal of the baseline analysis. One-way sensitivity analysis showed that under the health states of progression free survival and progressive disease ,utility value and the price of nivolumab had a greater impact on the ICER value. Probabilistic sensitivity analysis showed that the results of baseline analysis were robust. CONCLUSIONS At a 163.com willingness to pay threshold of 3 times of GDP per capita in nivolumab combined with ipilimumab is not cost-effective compared with chemotherapy regimen in the first-line treatment of unresectable MPM. However ,if patients receive complimentary drugs ,the dual-immunotherapy regimen is cost-effective.
摘要:OBJECTIVE To eval uate the cost-util ity of regimen containing bortezomib in the treatment of newly diagnosed multiple myeloma in China. METHODS From the perspective of China ’s health system ,Markov model was constructed based on SWOG S 0777 clinical trial. The simulation time limit was 10 years,and the cycle was set with reference to the treatment cycle. Taking quality adjusted life years (QALYs)as the utility index ,the utility and cost were discounted at a discount rate of 5%;the willingness to pay (WTP)threshold was set to be 3 times of China ’s per capita gross domestic product (GDP)in 2021(242 928 yuan/QALY). The incremental cost-utility ratio (ICER)of dexamethasone combined with bortezomib and lenalidomide (VRD) versus dexamethasone combined with lenalidomide (RD)were compared with cost-utility analysis. The sensitivity analysis was performed for the uncertainty of the model. RESULTS Results of baseline analysis showed that VRD regimen could obtain 0.65 more QALYs than RD scheme ,but its treatment cost was 135 782.77 yuan more than RD regimen ,ICER was 206 623.35 yuan/ QALY,which was lower than the WTP threshold set in this study ,VRD regimen was cost-effective. Single factor sensitivity analysis showed that the health utility value in progressive free survival had the greatest impact on the results ,the decrease of utility value would make the ICER higher than the WTP threshold ,and VRD regimen would no longer have advantages. Under the WTP threshold of 3 times of China ’s per capita GDP in 2021,the probability of VRD regimen being cost-effective was 86.5%; with the increase of WTP threshold ,the possibility of VRD regimen becoming more cost-effective than RD regimen would increase. CONCLUSIONS Under the WTP threshold of 3 times of China ’s per capita GDP in 2021,compared with RD regimen,VRD regimen is cost-effective in the treatment of newly diagnosed multiple myelo ma in China.
摘要:OBJECTIVE To provide reference for clinical safe and rational use of adalimumab by mining the risk signals of adverse event (AE). METHODS AE reports related to adalimumab were collected from FDA adverse event reporting system (FAERS)from Jan. 1st,2015 to Dec. 31th,2021. The reporting odds ratio (ROR)method and the Medicines and Healthcare Products Regulatory Agency (MHRA) method were adopted to mine the AE risk signals related to adalimumab ,AEs were classified and described by using the preferred system organ class (SOC)and preferred term (PT)of Medical Dictionary for Regulatory Activities (23.0). RESULTS A total of 149 203 AE reports related to adalimumab were screened ,among which 65 218 cases(43.71%)were severe AE reports. A total of 2 660 PTs were mined ,involving 27 SOCs. PTs related to primary disease (arthralgia,Crohn’s disease ,rheumatoid arthritis ,abdominal pain ,osteoarthritis,intestinal obstruction ,psoriasis,joint swelling , arthritis,etc.)were more frequently reported ,followed by PTs related to inflammation and pain (procedural pain ,inflammation, etc.). The main SOC included musculoskeletal and connective tissue diseases (68 227 cases),gastrointestinal diseases (50 682 cases),injury,poisoning and procedural complications (32 404 cases),infections and infestations (15 651 cases),general disorders and administration site conditions (15 424 cases),etc. CONCLUSIONS It is suggested to pay attention to the possible occurrence of paradoxical psoriasis and lupus-like syndrome related to the autoimmune system when using adalimumab clinically ; at the same time ,the attention should be paid to serious infection ,tuberculosis,malignant tumors ,demyelination,congestive heart failure and other AEs. If related AEs occurs ,intervention measures should be taken in time. Great importance should be paid to intracranial aneurysms ,ovarian cysts ,coronary artery occlusion ,thyroid masses and other AEs not mentioned in the instrcution ,to ensure the medication safety of patients.

摘要:OBJEC TIVE To investigate the status and clinical characteristics of adverse drug reactions (ADRs)induced by sintilimab in order to provide references for clinical rational drug use. METHODS The cases of ADR induced by sintilimab were retrieved from the databases of PubMed ,Embase,CNKI,VIP and Wanfang. RESULTS A total of 32 literature were included , involving 33 patients among which there were 25 males(75.76%)and 8 females(24.24%). The incidence of ADRs was higher in patients aged over 40 years(81.82%). The dose of sintilimab was the drug instructions recommended dose (200 mg)for 30 patients and 100 mg for a patient. The earliest ADR occurred 1 h after the first medication ,the latest ADR occurred after 14 cycles of sintilimab. The 27 cases suffered from ADR cases (81.82%)within 4 months after medication ,and no reports of ADR occurred after 12 months of medication. The major manifestations of ADR were myocarditis ,diabetes mellitus ,checkpoint inhibitor pneumonitis(CIP),cytokine release syndrome (CRS)and hypothyroid myopathy (HM),etc. CRS and HM belonged to ADRs not recorded in the drug instructions. The 29 cases of recovery and 4 deaths occurred after symptomatic treatment. CONCLUSIONS ADR caused by sintilimab often occurs within 4 months after treatment ,and it is high in males and patients over 40 years old. In clinical application of sintilimab ,attention should be paid to the occurrence of myocarditis ,diabetes mellitus ,CIP,as well as CRS and HM not recorded in the drug instructions.

摘要:OBJECTIVE To evaluate the bioequivalence and safety of two k inds of Nadroparin calcium injection in healthy Chinese volunteers by subcutaneous injection. METHODS According to the block randomization method ,24 Chinese healthy adult volunteers were included and divided into TR (test preparation-reference preparation )group and RT (reference preparation-test preparation)group at a ratio of 1∶1. A randomized ,open-labelled,single-dose and two-cycle crossover study was designed ,the fasting subjects of two groups were given test or reference preparation 6 150 AⅩaIU subcutaneously on the first day of each cycle and exchanged in the second cycle ,and the wash-out period was 7 days. The blood samples were collected at different time points before and after administration. The activity of anti-coagulant factor Ⅹa(Anti-Ⅹa)and Anti- Ⅱa in human plasma were determined by chromogenic substrate method ,and the pharmacodynamic parameters were calculated according to the non-atrioventricular model and the bioequivalence was evaluated. The occurrence of adverse events (AEs)was recorded. RESULTS After administration ,the main pharmacodynamic parameters for Anti- Ⅹa activity of test preparation and reference preparation were as follows :t1/2 were(4.87±1.06) and(4.03±1.00)h,tmax were 4.50(2.00,8.00)and 5.50(2.50,8.00)h,Anti-Ⅹamax were(0.66±0.12)and(0.56±0.11)IU/mL;main pharmacodynamic parameters of Anti- Ⅱa activity of two preparations were as follows :t1/2 were(3.64±1.60)and(5.74±7.23)h,tmax were 4.00(2.50,8.00)and 4.00(2.00,8.00)h,Anti-Ⅱamax were both (0.10±0.03)IU/mL. The values of 90%confidence interval of geometric mean ratio of Anti- Ⅹamax,AUEC0-t and AUEC 0-∞ were 110.98%-123.50%,112.11%-121.24%and 111.57%-120.00%, respectively. During experiment ,14 subjects reported 19 cases of mild AEs ,among which hematoma ,purpura and maculopapular rash may be related to drugs ;no serious AEs were observed. CONCLUSIONS The domestic Nadroparin calcium injection is bioequivalent to the reference preparation ,and both of them show good safety.
摘要:OB JECTIVE To conduct overview of the systematic revi ew(SR)/meta-analysis for the effectiveness and safety of pharmacological interventions for hospitalized neconatal pain , and to provide evidence-based reference for neonatal pain management. METHODS CNKI,CBM,Wanfang,VIP,PubMed,Embase,the Cochrane Library ,Web of Science ,CINAHL and Google Scholar were searched for SR/meta-analysis of pharmacological interventions for hospitalized neonatal pain. The search period was from Nov. 1st,2016-Nov. 1st,2021. After literature screening and data extraction ,AMSTAR 2 scale was used to evaluate the methodological quality of the included literature ,and GRADE method was used to assess the evidence quality of the outcome of the include d literature . A su mmary analysis was then conducted. RESULTS Totally 36 outcome indexes of 7 SR/ meta-analysis were included. Five studies were of moderate quality,and two were very poor according to AMSTAR 2 scale. GRADE results showed that among 36 outcome indexes,there were 7 moderate-quality indexes (19.44%),low-quality indexes (61.11%),and 7 critically-low-quality indexes (19.44%). The main reason for downgrading the quality of evidence was impr ecision of results (71.74%). CONCLUSIONS Opioids c an significantly reduce t he pain score of mechanically ventilated neonates but may increase hypotension. Acetaminophen can significantly reduce pain scores during eye examinations and postoperative morphine consumption with no adverse reaction report. However ,its analgesic effect on procedural pain is less than glucose and sucrose. Lidocaine and prilocaine and tetracaine may relieve venipuncture and lumbar puncture pain but lidocaine and prilocaine may increase the risk of adverse reaction. Clonidine can reduce neonatal mechanical ventilation pain with no adverse reaction report. It is suggested that neonatal pediatricians should use analgesic drugs selectively based on clinical judgment and pain assessment results.

摘要:Remote pharmaceutical care refers to the process that pharmacists provide pharmaceutical care to patients remotely through information technology. Remote pharmaceutical care in China starts late and develops slowly. Therefore ,this paper discusses the pharmaceutical care modes that pharmacists at home and abroad can provide under the remote mode by collecting literature. The results show that foreign remote pharmaceutical care starts early and is relatively mature. The service mainly included remote follow-up and intervention ,24-hour online prescription and order review ,24-hour online drug reorganization ,and guidance on rational drug use in remote areas or community hospitals. The service population covers patients with cardiovascular disease , diabetes,asthma,AIDS and so on. Some hospitals have established an integrated pharmaceutical care system of “Internet+Medical Consortium”in China ,with which pharmacists can provide patients with pharmaceutical care such as remote follow-up and intervention,drug consultation and so on. With the promotion of telemedicine ,domestic pharmacists can gradually expand the scope of services ,expand pharmaceutical services such as remote consultation and remote popular science push ,and realize the sharing of high-quality pharmaceutical care for the whole people.
摘要:Evidence-based Practice Guideline of Medication Therapy of High-dose Methotrexate in China was published in the British Journal of Clinical Pharmacology in February 2022. The guideline followed the latest definition of clinical practice guideline and the methodology specification for the guideline development of WHO. The Grading of Recommendations Assessment , Development,and Evaluation (GRADE)approach was applied to rate the quality of evidence and determine the strength of recommendations. Finally ,this guideline presents 28 recommendations covering the whole process of clinical medication of high-dose methotrexate ,involving evaluation prior to administration (liver and renal function ,pleural effusion and ascites , comedication,genetic testing ),pre-treatment and routine dosing regimen (pretreatment of hydration and alkalization ,urine alkalization,routine dosing regimen ),therapeutic drug monitoring (necessity,method,timing,target concentration ),leucovorin rescue(rescue timing ,rescue regimen ,rescue dose optimization ),and management of toxicities (liver and kidney function monitoring,supportive treatment ,blood purification treatment ). This article aims to summarize and interpret the recommendations of this guideline ,so as to promote the better promotion and implementation of this guideline and provide comprehensive technical support and suggestions for whole-course individualized administration of high-dose methotrexate in China.
摘要:Selexipag i s a kind of oral highly selective prostacyclin (IP)receptor agonist ,which can inhibit the contraction and proliferation of pulmonary artery smooth muscle cells. Because of its good patient compliance and high receptor affinity ,it is currently used in the treatment of pulmonary hypertension (PH). This article reviews the mechanism of action ,pharmacokinetics/ pharmacodynamics and application of selexipag in the treatment of PH. The results show that selexipag alone or in combination with endothelin receptor antagonists and (or)phosphodiesterase inhibitors can effectively reduce the risk of worsening/death events , delay disease progression ,and improve patients ’life quality in patients with adult pulmonary arterial hypertension (PAH)of WHO cardiac function Ⅱ-Ⅲ grade. However ,its application in children with PAH and patients with chronic thromboembolic PH needs further exploration.
