The regression analysis was carried out for the influential factors of pharmaceutical clinic service.RESULTSA total of 1 368 questionnaires were distributed in this survey and 1 304 valid questionnaires were collected with the effective response rate of 95.32%. A total of 463 medical institutions carried out pharmaceutical clinic service， the rate of which was 35.51% （463/1 304）； the rates of pharmaceutical clinics in tertiary， secondary， primary and other medical institutions were 52.80%， 17.18% and 5.88%， respectively. The frequency of opening pharmaceutical clinics was 3.17 days per week on average， with an average of 5.99 visiting pharmacists in each medical institution. Among the visiting pharmacists， clinical pharmacists accounted for the vast majority （88.68%， 2 459/2 773）. There were various categories of pharmaceutical clinics， including joint clinics and pharmacist-independent clinics； among pharmacist-independent clinics， pharmaceutical specialty/specialty disease clinics were the main ones， accounting for 89.72% of the total number of pharmaceutical clinics. The value of pharmacists in pharmaceutical clinics was manifested in various forms， among which the proportion of medical institutions charging pharmaceutical clinics was 10.80%. The main experiences in developing pharmaceutical clinics were to attach importance to discipline construction and personnel training. The main difficulties in developing pharmaceutical clinics were low compensation levels and a shortage of talent. The number of clinical pharmacists， the number of visiting pharmacists in pharmaceutical clinics and additional compensation were positively correlated with the amount of pharmaceutical clinic services（P＜0.05）.CONCLUSIONSIn recent years， pharmaceutical clinics have made significant progress； in the future， it is still necessary to further strengthen discipline construction and talent cultivation， pay attention to the value embodiment of pharmacists， to promote the healthy development of pharmaceutical clinics.关键词：current situation;questionnaire survey;value embodiment

The depression model was induced by chronic unpredictable mild stress （CUMS） method in the modeling group. After 21 days of stimulation， the rats of modeling group were randomly divided into depression model group （NS group）， positive control group [ECS group， oxalate escitalopram 15 mg/（kg·d）] and ICSⅡ low-dose， medium-dose and high-dose groups [ICSⅡ-L group， ICSⅡ-M group， ICSⅡ-H group； ICSⅡ 10， 20， 30 mg/（kg·d）]， with 10 mice in each group. Administration groups were given relevant medicine intragastrically， once a day， for 14 consecutive days. The sugar water preference rate， total exercise distance， immobility time in tail suspension and forced swimming experiments were detected in each group. The morphology of neurons and Nissl bodies in the hippocampal CA3 region were observed； the contents of γ-aminobutyric acid （GABA） and glutamic acid （Glu）， GABA/Glu ratio， and the expressions of GABAergic nervous system-related proteins （GABA A receptor α1， GABA B receptor 1， vesicular GABA transporter， glutamate decarboxylase 67， GABA membranal transporter 3） were detected in hippocampus.RESULTSCompared with group C， the sugar water preference rate and the total exercise distance significantly reduced in NS group， while the values of immobility time in the tail suspension test and forced swimming test were significantly prolonged （P＜0.05）. The morphology of neurons in the CA3 area of the hippocampus was irregular and the Nissl bodies were reduced， with a significant decrease in the number of structurally intact neurons （P＜0.05）； the content of Glu was significantly increased， while the content of GABA， GABA/Glu ratio， and the expressions of GABAergic nervous system-related proteins were significantly decreased （P＜0.05）. Compared with NS group， depression behavior in each administration group was improved， and the above indexes were mostly reversed （P＜0.05）.CONCLUSIONSICSⅡ can improve depression behavior of depression model mice. The mechanisms may be associated with regulating the balance of GABA and Glu， increasing the synthesis， transport and release of GABA， and regulating the expressions of GABA-related receptors， so as to improve GABAergic nervous system.关键词：depression;chronic unpredictable mild stress;GABAergic nervous system

Chaenomeles sinensis and content determination of 3 flavones摘要：OBJECTIVETo establish the characteristic chromatogram of Chaenomeles sinensis， determine the contents of rutin， hyperin and quercitrin， and to identify C. sinensis and C. speciosa.METHODSHPLC method was performed on Agilent 5 TC-C18 column， with acetonitrile-0.2% formic acid solution as the mobile phase for gradient elution， at the flow rate of 1.0 mL/min. The column temperature was 30 ℃. The detection wavelength was 330 nm in characteristic chromatogram and 350 nm in content determination. The characteristic chromatogram of C. sinensis was established and similarity was evaluated by the Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 edition）. Hierarchical cluster analysis of 15 batches of C. sinensis （S1-S15） was performed by using SPSS 23.0 software. The contents of 3 flavones in 15 batches of C. sinensis and 7 batches of C. speciosa （S16-S22） were determined， while their characteristic chromatograms were compared.RESULTSThe similarities of the characteristic chromatogram for 15 batches of C. sinensis ranged from 0.783 to 0.969， and 11 characteristic peaks were confirmed. Four constituents were identified as chlorogenic acid， rutin， hyperin and quercitrin. The medicinal materials in 15 batches of C. sinensis could be divided into 2 categories： S5-S8 were one category， and the others belonged to one category. The characteristic chromatogram of C. sinensis was obviously different from C. speciosa. The contents of rutin， hyperin and quercitrin in 15 batches of C. sinensis were 48.99-294.45， 3.49-102.55， 31.98-149.49 μg/g， respectively. The content of rutin in C. speciosa was lower than that in C. sinensis. None of hyperin （except for S20） and quercitrin were detected in C. speciosa.CONCLUSIONSThe characteristic chromatogram and the method for content determination of 3 flavones in C. sinensis are established successfully and can be used for the quality control of C. sinensis and its identification from C. speciosa.关键词：flavones;characteristic chromatogram;HPLC- 17

发布时间：2024-01-24 - 摘要：OBJECTIVETo investigate the effects of the peroxisome proliferator-activated receptors δ （PPARδ） agonist GW501516 on the injury of pulmonary artery endothelial cells （PAECs） induced by hypoxia and its mechanism.METHODSThe cytotoxic effects of GW501516 were observed by detecting the relative survival rate of PAECs； the protein expression of PPARδ was determined by Western blot assay. The cellular model of PAECs injury was established under hypoxic conditions； using antioxidant N-acetylcysteine （NAC） as positive control， the effects of GW501516 on cell injury and reactive oxygen species （ROS） production were investigated by detecting cell apoptotic rate， cell viability， lactate dehydrogenase （LDH） activity and ROS levels. Using nuclear factor erythroid 2-related factor 2（Nrf2） activator dimethyl fumarate （DMF） as positive control， PAECs were incubated with GW501516 and/or Nrf2 inhibitor ML385 under hypoxic conditions； the mechanism of GW501516 on PAECs injury induced by hypoxia was investigated by detecting cell injury （cell apoptosis， cell viability， LDH activity）， the levels of superoxide dismutase （SOD）， glutathione peroxidase （GPx）， catalase （CAT）， malondialdehyde （MDA） and ROS， the expressions of Nrf2， heme oxygenase-1 （HO-1） and cleaved-caspase-3 （C-caspase-3） protein.RESULTSThe results demonstrated that hypoxia inhibited the protein expression of PPARδ （P＜0.05）， while GW501516 promoted the protein expression of PPARδ in hypoxia-exposed PAECs without obvious cytotoxic effects. GW501516 inhibited the apoptosis of PAECs， improved cell viability， and reduced LDH activity and ROS levels. GW501516 could up-regulate the protein expression of HO-1 in PAECs and the levels of SOD， GPx and CAT， while down-regulated the levels of MDA and ROS by activating the Nrf2 pathway （P＜0.05）； but Nrf2 inhibitor ML385 could reverse the above effects of GW501516 （P＜0.05）. GW501516 exerted similar effects to Nrf2 activator DMF in down-regulating the expression of C-caspase-3 and inhibiting the injury of PAECs under conditions of hypoxia （P＜0.05）. Moreover， Nrf2 inhibitor ML385 reversed the inhibition effects of GW501516 on PAECs injury （P＜0.05）.CONCLUSIONSGW501516 can relieve the hypoxia-induced injury of PAECs via the inhibition of oxidative stress， the mechanism of which may be associated with activating Nrf2.关键词：hypoxia;pulmonary artery endothelial cells;oxidative stress;injury;nuclear factor erythroid 2-related factor 2

The incremental cost-effectiveness ratio （ICER） was calculated by using quality-adjusted life years （QALY） as output indicators， and sensitivity analysis was used to verify the robustness of the basic analysis results； the cost-effectiveness of the second-line treatment for HER2-positive metastatic breast cancer was compared between T-DXd and T-DM1.RESULTSUnder the premise of taking 3 times China’s per capita gross domestic product （GDP） in 2022 as the willingness-to-pay threshold （257 094 yuan/QALY）， the T-DXd group also needed to pay more cost compared with T-DM1 group while obtaining incremental utility （0.69 QALYs）， and the ICER value was 1 850 478.40 yuan/QALY. The results of univariate sensitivity analysis showed that progression-free survival state utility value， T-DXd price， cost discount rate were factors that had a great influence on ICER value， but these parameters could not flip the basic analysis results within a reasonable range. In the probability sensitivity analysis， when the threshold of willingness-to-pay rose to 1 500 400 yuan/QALY， the probability of economic activity was 50% in the T-DXd regimen. The results of the scenario analysis also verified the robustness of the original research results.CONCLUSIONSUnder the premise of 3 times China’s per capita GDP as the WTP threshold， compared with T-DM1， T-DXd is not cost-effective in the second-line treatment of HER2-positive metastatic breast cancer.关键词：trastuzumab emtansine;HER2-positive metastatic breast cancer;partitioned survival model;cost-utility analysis

Data mining was performed by using the reporting odds ratio （ROR） and proportional reporting ratio （PRR） methods， and categorization statistics were performed by using the system organ class （SOC） and preferred term （PT） from drug ADE terminology set in the MedDRA （version 26.0）.RESULTSA total of 3 084 ADE reports were obtained for selinexor， with a total of 134 ADE-positive signals. Among the reported genders， there were 127 males and 124 females， with a predominant age of ≥65 years old （4.12%）； the United States had the highest number of reports （96.53%）， with consumers being the main reporters （77.27%）； severe ADR was mainly characterized by hospitalization/prolonged hospitalization （26.26%）， followed by death （17.15%）. The top 3 ADE in the list of frequency were nausea （1 162 times）， fatigue （790 times） and anorexia （610 times）， all of which were mentioned in the selinexor’s instructions. The top 3 signals in the list of strength were device-associated bacteremia （ROR＝115.07， PRR＝114.94）， blepharospasm dysfunction （ROR＝106.70， PRR＝106.54）， and salmonella sepsis （ROR＝99.90， PRR＝99.81）， all of which were not mentioned in the selinexor’s instructions.CONCLUSIONSIn addition to the ADE of nausea mentioned in the instruction manual， attention should also paid to device-associated bacteremia， blepharospasm dysfunction， salmonella sepsis， and other ADE not mentioned in the instruction manual when using selinexor in clinical practice； weekly rechecking of the patient’s blood routine should be done to monitor the patient’s blood indexes， symptoms of infection， and so on， to ensure that the safety of drug use.关键词：adverse drug event;signal mining;FDA adverse event reporting system

发布时间：2024-01-24 - 摘要：OBJECTIVETo investigate the effects of renally inappropriate medication （RIM） on the frailty of elderly patients with diabetes.METHODSThe data of elderly patients with diabetes mellitus admitted to a third-grade class A hospital in Yunnan province from January to December 2022 were collected， and Beers criteria （2019 edition） and Chinese version of FRAIL scale were used to evaluate RIM and the frailty of the patients； the patients were divided into the trial group （with RIM） and the control group （without RIM） according to whether there was RIM. The propensity score matching was used to balance confounding factors between two groups， and the influence of RIM on the frailty of elderly diabetic patients was analyzed by the Logistic regression model.RESULTSAmong the 367 patients， 80 patients （21.80%） had RIM， the drugs involved RIM were spironolactone （82.56%）， rivaroxaban （13.95%） and gabapentin （3.49%）. After reaching the balance between groups using the propensity score matching method， the incidence of frailty was 77.94% in trial group and 27.94% in control group （P＜0.001）； the difference was not statistically significant in other confounding factors between the two groups （P＞0.05）. Results of Logistic regression analysis showed that the risk of frailty in the experimental group was 3.118 times that of the control group （odds ratio was 3.118，95% confidence interval was 1.758-5.530， P＜0.001）.CONCLUSIONSRIM is a risk factor for the frailty of elderly patients with diabetes， which can be considered as an indicator for early identification and screening of the frailty of elderly diabetes patients.关键词：frailty;elderly;diabetes;propensity score matching

After literature screening， data extraction and quality evaluation， the meta-analysis was conducted by using RevMan 5.4 software.RESULTSA total of 22 studies were included， involving 9 RCTs and 13 cohort studies. RCT results showed that the incidences of deep vein thrombosis （DVT） [RR＝1.81， 95%CI（1.36， 2.40）， P＜0.000 1] and postoperative pulmonary embolism （PE） [RR＝1.55， 95%CI（1.01， 2.40）， P＝0.05] in trial group were significantly higher than control group. There was no statistically significant difference in the incidences of postoperative massive bleeding， postoperative surgical site infection， all-cause death， or any bleeding after surgery between 2 groups. In the cohort study， the incidence of any bleeding in trial group was significantly lower than control group [RR＝0.71， 95%CI （0.64， 0.79）， P＜0.000 1]， while the differences in other indicators were not statistically significant （P＞0.05）. The results of subgroup analysis based on different anticoagulants showed that in RCT， the incidences of DVT and PE after surgery in patients using low-molecular-weight heparin （LMWH） were significantly lower than using aspirin （P＜0.05）； in the cohort study， the incidences of DVT and PE after surgery were significantly lower in patients using direct oral anticoagulants （DOAC） than using aspirin （P＜0.05）. There was no statistically significant difference in the incidence of major bleeding between patients using aspirin and using DOAC and LWMH （P＞0.05） in both RCT and cohort study.CONCLUSIONSAspirin is equally safe as other anticoagulants for the prevention of thromboembolism after orthopedic surgery， but its efficacy may not be as good as other anticoagulants. After orthopedic surgery， other anticoagulants should be preferred to prevent venous thromboembolism， and aspirin should be carefully considered.关键词：aspirin;anticoagulants;thromboembolism;efficacy;safety;meta-analysis

Potential failure modes that might lead to dispensing errors in each link were determined， and failure causes were analyzed. The severity， incidence and detection degree of potential failure modes were quantitatively scored， and their risk priority number （RPN） was calculated to screen failure modes that needed to be improved in priority； the corresponding improvement measures were developed by 6S management method from six aspects， namely， finishing （seiri）， rectifying （seiton）， sweeping （seiso）， sanitation （seiketsu）， literacy （shitsuke） and safety. The effect of intervention before and after rectification was evaluated.RESULTSBased on the RPN， 32 potential failure modes were selected， of which a total of 18 critical failure modes that needed to be improved in priority. After implementing corresponding measures according to 6S management method， the RPN of 18 critical failure modes decreased. The total RPN decreased from 497 to 142 with a decrease rate of 71.43%. The error rates of 15 critical failure modes were significantly lower than before implementation （P＜0.05）.CONCLUSIONSApplying FMEA model and 6S management method to the risk control of all aspects of PIVAS workflow can effectively reduce the risk of PIVAS dispensing errors and ensure the safety of children’s intravenous medication.关键词：dispensing errors;risk evaluation;failure mode and effect analysis;6S management

发布时间：2024-01-24 - 摘要：Levetiracetam （LEV） is the second generation of broad-spectrum anti-epileptic drug. LEV has the advantages of rapid absorption， short half-life， precise efficacy， good tolerance and few drug interactions. In order to improve the clinical efficacy of LEV， and reduce the occurrence of adverse reactions， children， pregnant women， the elderly， and patients with renal insufficiency should receive therapeutic drug monitoring （TDM）. Clinically， the samples are usually plasma or serum， and the TDM methods are mostly immunoassay or chromatography. There is currently no consensus on the effective concentration range of LEV， and the correlation between plasma concentration and adverse reactions is also unclear. The main factors affecting LEV plasma concentration include age， pregnancy， and patient compliance. How to interpret TDM results and adjust dosage based on the results will be the focus of future work.关键词：therapeutic drug monitoring;rational drug use;plasma concentration
