- 摘要：OBJECTIVETo provide reference for the regulation of electronic prescription circulation under the mode of “medical science + pharmacy”.METHODSBased on evolutionary game theory， a tripartite evolutionary game model was constructed for related parties of electronic prescription circulation （government agencies， internet hospitals and third-party drug platforms） under the mode of “medical science + pharmacy”. The influential factors of the three parties’ strategy selection were analyzed and verified by simulation. RESULTS &CONCLUSIONSThe strategic choices of all parties in the game were affected by the other two parties. Reducing the cost of strict supervision or increasing the punishment for the other two parties would increase the probability of strict supervision of government agencies. Enhancing reputation losses， increasing penalties， and reducing the cost difference when choosing different strategies would have regulatory and binding effects on internet hospitals and third-party drug platforms. It is suggested that government agencies can introduce diversified supervision mode and establish an integrated “intelligent supervision + traceability” system； pay attention to the construction of reputation mechanism， and promote the coordinated linkage of all parties； increase the punishment for violations， provide policy support， reduce the cost of compliance behavior to promote the high-quality development of electronic prescription circulation under the mode of “medical science + pharmacy”.关键词：evolutionary game;prescription regulation;internet hospital;third-party drug platforms

Except for the blank group， the IPF model was induced in other groups by intratracheal instillation of bleomycin （5 mg/kg）. Starting from the day of modeling， the blank group and model group were given normal saline （10 mL/kg） intragastrically， while the rats in the positive control group were given dexamethasone solution （5 mg/kg） intragastrically， BYHW low-dose， middle-dose and high-dose groups were treated with BYHW （2.5， 5， 10 g/kg， by crude drug） intragastrically， once a day， for 28 consecutive days. The body mass of rats in each group was measured on days 0， 7， 14， 21 and 28 after modeling. The number of adherent white blood cells in pulmonary veins was observed by a dynamic visualization system. The contents of TNF-α and IL-6 in serum and TNF-α， IL-6， HYP and TGF-β1 in lung tissue were detected； the protein expression of ZO-1 was also detected. The pathomorphological changes in lung tissue were observed.RESULTSCompared with the model group， the body weight of rats all increased significantly in BYHW high-dose and middle-dose groups， positive control group， while the number of adherent white blood cells in pulmonary veins was decreased significantly； the contents of TNF-α （except for serum in BYHW middle-dose group） and IL-6 in serum and lung tissue， the contents of HYP and TGF-β1 in lung tissue were decreased significantly， while the protein expression of ZO-1 in the lung tissue was increased significantly （P＜0.05 or P＜0.01）. The pathological changes of lung tissue were improved to varying degrees.CONCLUSIONSBYHW may play anti-pulmonary fibrosis role by improving leukocyte adhesion， anti-inflammatory， anti-fibrosis， and other aspects of pulmonary microcirculation.关键词：pulmonary fibrosis;microcirculation;zonula occludens-1

Based on the analytic hierarchy process （AHP） and Plackett-Burman design， with the concentrations of the 7 components as evaluation indexes and the crushing degree， ethanol concentration， and soaking time as factors， the extraction process of P. corylifolia was optimized by Box-Behnken response surface methodology and the validation test was conducted. Zebrafish were divided into blank control group， positive control group （8-methoxypsoralen， 10.8 μg/mL）， and low-， medium-， and high-concentration groups of P. corylifolia extract （500， 1 000， 2 000 μg/mL）， with 6 fish in each group. The effects of P. corylifolia extract on the melanin production of zebrafish were studied by density analysis.RESULTSThe best extraction process was P. corylifolia powder over 60 meshes and soaked in 80% ethanol for 72 hours. The average comprehensive score of three validation experiments was 98.27， with an RSD of 1.36%， and the relative error was 1.02% compared with the predicted value of the fitting equation （97.28）. Compared with the blank control group， the melanin pigmentation of zebrafish in the low-， medium-， and high-concentration groups of P. corylifolia extract was significantly increased （P＜0.01）.CONCLUSIONSThe optimized extraction process of P. corylifolia is reasonable and feasible， and the obtained P. corylifolia extract can significantly promote the production of melanin in zebrafish.关键词：effective component;extraction process;analytic hierarchy process;Plackett-Burman design;Box-Behnken response surface methodology;melanin;vitiligo

Then， 10 mice were randomly selected and injected with normal saline through the trachea， and the other 50 mice were all injected with porcine trypsin solution （concentration of 33.3 mg/mL， dosage of 1.0 mL/kg） to induce the COPD model. After normal feeding for 28 days， the mice were divided into sham operation group， model group， budesonide group （20 mg/kg）， Cur-SLN-FL high-dose and low-dose groups （100， 50 mg/kg）， with 10 mice in each group. The corresponding drugs were given to each group， once a day， for 14 consecutive days. Twenty-four hours after the last administration， the bronchoalveolar lavage fluid （BALF） of mice in each group was collected and the differential count of white blood cells was determined. Hematoxylin-eosin （HE） staining was used to observe the histopathology of the trachea and lung tissue in each group. Masson staining was used to detect collagen deposition in the lung tissue of mice in each group. Immunohistochemical method was used to detect the positive expressions of nucleotide-binding oligomerization domains-like receptor protein-3 （NLRP3）， caspase-1 and interleukin-1β （IL-1β） in lung tissue of mice. Western blot assay was used to detect the protein expressions of NLRP3， caspase-1 and nuclear factor of kappa B（NF-κB） in lung tissue.RESULTSCur-SLN-FL had no obvious pulmonary irritation. Compared with the sham operation group， the total number of white blood cells， neutrophils and eosinophils in BALF of the model group increased significantly， while the number of lymphocytes decreased significantly （P＜0.05）； ciliated columnar epithelium proliferated， thickened and exfoliated in the trachea， mucus accumulated in the cavity and interstitial inflammatory cells infiltrated in the lung tissue； the deposition of collagen fibers in lung tissue increased significantly， the positive expressions of NLRP3， caspase-1 and IL-1β in lung tissue increased significantly， and the expressions of NLRP3， caspase-1 and NF-κB protein in lung tissue all increased significantly （P＜0.05）. After giving Cur-SLN-FL， the above indexes were all improved to certain extent.CONCLUSIONSCur-SLN-FL can improve the pulmonary inflammatory reaction in COPD model mice， and its mechanism may be through regulating the NLRP3 signaling pathway， inhibiting the expressions of caspase-1， NF-κB and IL-1β， thus alleviating the process of pulmonary fibrosis in COPD model mice.关键词：curcumin solid lipid nanoparticles;power inhalation;pulmonary irritation;chronic obstructive pulmonary disease;NLRP3 inflammatory corpuscles

TFB low-dose， medium-dose and high-dose groups were given TFB solution intragastrically at 60， 120 and 240 mg/kg， and the normal control group and LPS group were given corresponding volume of normal saline， once a day， for consecutive 21 d. From the 15th day of administration， except for the normal control group， other groups were given LPS （400 μg/kg） intraperitoneally for 7 consecutive days to establish neuroinflammatory model. Brain tissues were taken under anesthesia 4 h after the final administration. The morphological changes of neuronal cells in mice were observed； the contents of nitric oxide （NO）， tumor necrosis factor α （TNF-α）， interleukin-1β （IL-1β）， IL-6 and IL-10 were measured， and the expressions of inflammatory pathway-related proteins [inducible NO synthase （iNOS）， cyclooxygenase-2 （COX-2）， myeloid differentiation factor 88 （Myd88） and protein kinase C （PKC）] were measured in the brain tissues of mice.RESULTSCompared with the normal control group， the neuronal arrangement in the hippocampal region of the brain tissue of mice in the LPS group was sparsely disorganized， with a large number of neuronal fixations and shrunken nuclei； the contents of TNF-α， IL-1β， IL-6 and NO in the brain tissue were significantly increased， the contents of IL-10 were significantly decreased， and the relative expressions of iNOS， COX-2， Myd88 and PKC proteins were significantly increased （P＜0.05）. Compared with the LPS group， the neuronal pathological changes in the brain tissue of mice in the TFB low-dose， medium-dose and high-dose groups were significantly improved， and the changes of the above indices in the brain tissue were significantly reversed （P＜0.05）.CONCLUSIONSTFB has an inhibitory effect on neuroinflammation， and its mechanism of action may be related to down-regulation of the expressions of inflammatory pathway-related proteins iNOS， COX-2， Myd88 and PKC， and reduction of inflammatory factors release.关键词：lipopolysaccharide;neuroinflammation;inflammatory factors

发布时间：2023-07-24 - 摘要：OBJECTIVETo evaluate the cost-effectiveness of serplulimab combined with chemotherapy as first-line treatment for advanced esophageal squamous cell carcinoma from the perspective of the Chinese healthcare system.METHODSA partitioned survival model with three health states was constructed for cost-effectiveness analysis. Clinical data were extracted from ASTRUM-007. Information on parameters such as cost and health utility was derived from related websites and published literature. The quality-adjusted life years （QALYs） was used as the output index to calculate the incremental cost-effectiveness ratio （ICER）， and then compared with three times the per capita gross domestic product （GDP） in China to judge whether it was cost-effective. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to evaluate the robustness of the model； the cost-effectiveness of applying this plan to subgroup patients with programmed cell death-ligand 1 combined positive score （PD-L1 CPS） ≥10 and the scheme in the context of charitable drug donations was explored.RESULTSAmong advanced or metastatic oesophageal squamous cell carcinoma patients and patients with PD-L1 CPS ≥10， serplulimab combined with chemotherapy could improve health outcomes with an augmentation of cost， compared with placebo combined with chemotherapy，resulting the ICERs were 599 623.64 yuan/QALY and 629 121.57 yuan/QALY， respectively. Therefore， serplulimab combined with chemotherapy was not cost-effective. Sensitivity analysis of single factor showed that the costs of serplulimab were the crucial factor affecting the ICER； probabilistic sensitivity analysis demonstrated basic analysis results were relatively robust. The results of scenario analysis showed that when all patients met the requirements of the charitable drug donation program， serplulimab combined with chemotherapy was cost-effective； the economic outcome of this scheme was reversed compared with the results of the basic analysis.CONCLUSIONSFrom Chinese healthcare perspective， first-line treatment with serplulimab in combination with chemotherapy is not a cost-effective option for patients with advanced esophageal squamous cell carcinoma， but it may be an economic option to implement a charitable drug donation program for all patients or if the price of serplulimab is significantly reduced.关键词：serplulimab;subgroup analysis;cost-effectiveness analysis

发布时间：2023-07-24 - 摘要：Abiraterone is commonly used as a targeted drug for the treatment of prostate cancer， which commonly causes adverse drug reactions （ADR）， including abnormal liver function， fatigue， nausea and edema， etc. This study reports a 78-year-old man with a history of hepatitis B and liver cirrhosis after prostate cancer resection who was admitted to the First Affiliated Hospital of Henan University of Chinese Medicine. The patient received abiraterone treatment 1 month before admission and developed gastrointestinal symptoms 3 weeks after the treatment and worsened at 4th week with yellowing of the skin， sclera and urine. Unfortunately， the patient died after 5 weeks of abiraterone treatment （1 week after admission）. Based on test and examination results， the patient was diagnosed with acute-on-chronic liver failure （ACLF）. This paper analyzes the patient’s medical history and the relevant treatment in detail. It is evaluated that ACLF and abiraterone are “probably” related based on Naranjo ADR Probability Scale， suggesting abiraterone may induce severe ADR of liver failure in patients with chronic liver diseases such as cirrhosis. These patients should be monitored dynamically for changes in liver function and treated prophylactically with liver-protective drugs if necessary.关键词：acute-on-chronic liver failure;adverse drug reaction;liver failure

One or two steady-state blood drug concentration samples were collected from each patient. NONMEM 7.2.0 software was used to establish a population pharmacokinetics model of dabigatran； the effects of different covariates on the apparent clearance of dabigatran were investigated， and the final model was verified by goodness of fit and Bootstrap method； NONMEM 7.2.0 software was used to analyze the drug exposure of ordinary elderly patients and elderly patients after taking dabigatran ester in different disease states.RESULTSTotally 122 blood concentration samples of dabigatran were collected. Advanced age， creatinine clearance and history of chronic heart failure were screened out as three significant covariates that influenced the clearance of dabigatran in elderly patients. The exposure of population with advanced age increased by about 50% compared with the general elderly， the exposure of population with history of chronic heart failure increased by nearly 30% compared with population without， and the exposure of population with moderate and severe renal injury increased by about 30% and 80% compared with mild.CONCLUSIONSAdvanced age， renal injury and history of chronic heart failure are influential factors for elevated systemic exposure of dabigatran.关键词：non-valvular atrial fibrillation;population pharmacokinetics;elderly patient

Those case reports were analyzed statistically in terms of gender， age， primary disease， drug use， clinical manifestations， treatment and outcome.RESULTSA total of 15 pieces of literature were collected and 17 patients were involved， including 10 males and 7 females. The average age of patients was （59.35±15.72） years. Among 17 patients， there were 10 patients with renal cell carcinoma and 7 patients with gastrointestinal stromal tumor， all of whom received evidence-based medication； the dosage of sunitinib in 15 cases was recorded， and all of them were within the recommended range of the instructions； 9 patients received combined therapy； the time from sunitinib application to the occurrence of nephrotic syndrome was 21 days-52 months， of which 11 cases were ≤2 years. The clinical manifestations in 13 patients were described， including edema， oliguria， foamy urine， weight gain， fatigue， dyspnea on exertion， etc. Eight patients had other adverse reactions induced by sunitinib before suffering from nephrotic syndrome， including new hypertension or worsening of original hypertension， and hand-foot syndrome. Renal biopsy mainly manifested as thrombotic microangiopathy， focal segmental glomerular sclerosis and immune complex glomerulonephritis. Sunitinib withdrawal or dosage reduction was adopted in all patients， and they were given symptomatic treatment such as glucocorticoids and antihypertensive agents. Symptoms of 16 patients were improved， and renal function of one patient deteriorated and hemodialysis was started. Sunitinib was re-challenged in 6 patients， elevated creatinine and substantial proteinuria recurred in 5 patients.CONCLUSIONSIn clinical use of sunitinib， it is advisable to periodically monitor renal function. In case of deterioration of renal function， albuminuria， edema， etc.， relevant examinations should be implemented in time， and symptomatic intervention should be taken as soon as possible. Besides， we should be alert to the recurrence of nephrotic syndrome after sunitinib rechallenge.关键词：adverse drug reaction;nephrotic syndrome;literature analysis

发布时间：2023-07-24 - 摘要：OBJECTIVETo analyze the clinical manifestation and characteristics of ocular adverse drug reaction （ADR） related to dupilumab， so as to provide reference for clinically safe drug use.METHODSRetrieved from CNKI， Wanfang data， VIP and PubMed databases， the case reports about ocular ADR caused by dupilumab were collected， and then analyzed statistically in terms of gender， age， primary disease， drug use， occurrence time of ADR， main clinical manifestations， treatment or outcome， etc.RESULTSA total of 20 pieces of literature were selected， involving 46 patients， among which there were 29 males and 17 females. Mainly patients were under 60 years old. The results of the association evaluation was given as follows： 13 were “very likely” and 33 were “likely”. All patients were treated with dupilumab for atopic dermatitis （AD） without off-label medication. The occurrence time of ADR was 2 weeks to 2 years after administration， mainly within 6 months after medication. All patients received dupilumab monotherapy except that 3 patients with hypertension and 1 patient with chronic obstructive pulmonary disease and human immunodeficiency virus received other drugs simultaneously. Twenty-eight patients had a history of allergic disease， and 11 patients had a history of eye disease. Ocular ADRs were mainly conjunctivitis and uveitis， and the clinical manifestations mainly included conjunctival congestion， swelling， eye secretions， etc. Ten patients developed severe ADR， including uveitis， severe conjunctivitis， and tear point stenosis； 45 patients were improved after symptomatic treatment. AD， serious initial symptoms of AD， allergic disease and underlying ocular diseases might be the high-risk factors of ocular ADR caused by dupilumab.CONCLUSIONSWhether the patient has the history of allergic diseases and basic eye diseases should be asked in detail before clinical use of dupilumab. When using the drug， attention should be paid to monitoring whether the patient has intraocular inflammation， be alert to the occurrence of new or serious ADR， and give timely symptomatic treatment to ensure the safety of drug use.关键词：retinitis;uveitis;ocular adverse drug reaction;literature analysis

发布时间：2023-07-24 - 摘要：OBJECTIVETo systematically analyze the related clinical research of therapeutic drugs for rotavirus infection in children， and to provide reference for the improvement of scientific and normative implementation in clinical trials.METHODSPubMed， the Cochrane Library and Embase databases were systematically searched， and English literature on randomized controlled trials （RCTs） about therapeutic drugs for pediatric rotavirus infection published between 2000 and 2022 was included. After literature screening and data extraction， the quality of the included literature was evaluated using the bias risk assessment scale recommended by Cochrane Handbook for Systematic Reviews. The research objectives， overall design， subject inclusion and exclusion criteria， interventions， course of treatment， follow-up visits， efficacy and safety evaluations， and results were analyzed descriptively. RESULTS &CONCLUSIONSA total of 17 RCTs were included， involving 1 345 subjects. The purpose included relieving rotavirus infection-induced diarrhea， promoting rotaviral shedding， improving clinical symptoms such as dehydration， fever， vomiting， and shortening hospital stays， etc. All trials were randomized and single-center studies， mostly double-blind （13 trials） and placebo-controlled （16 trials）， and 64.71% had sample size estimation. The inclusion and exclusion criteria included diarrhea attack， virus detection， clinical symptoms， disease types and drugs， etc. The interventions included probiotics （8 trials）， biological agents （3 trials）， anti-infective agents （3 trials）， etc. Most of treatment course was 1-5 days （13 trials）. A total of 58.82% were designed for follow-up. In the validity evaluation， diarrhea attack， microbiology test and fecal culture， clinical symptoms such as dehydration， fever and vomiting， length of hospital stays or duration of symptoms were included. Vesikari scale， WHO criteria and researcher evaluation were the evaluation criteria. In the safety evaluation， 10 trials were designed for adverse events/adverse reaction observation； only one trial listed ethical approval numbers. The information of literature included in the study covers the basic elements for the design of RCTs of drugs for rotavirus infection in children. Nevertheless， all are single-center studies. Partial studies lack the basis for sample size estimation and related contents of drug combination， and the quality needs to be improved. In the future， the high-quality multi-center clinical trials should be further conducted， with objective measurement indexes as the validity results， and the ethical review and safety evaluation should be emphasized.关键词：children;randomized controlled trials;design elements

摘要：OBJECTIVETo comprehensively evaluate four weekly preparations of glucagon-like peptide-1 receptor agonist（GLP-1RA） marketed in China，and to provide evidence for hospitals to optimize drug catalogs and clinical rational drug use.METHODSMini health technology assessment method was used to establish detailed evaluation rules according to A Quick Guideline for Drug Evaluation and Selection in Chinese Medical Institutions， and conduct comprehensive evaluation of four GLP-1RA weekly preparations from aspects of pharmaceutical characteristics， effectiveness， safety， economy and other attributes.RESULTSMini health technology assessment scores of the four GLP-1RA weekly preparations from high to low were dulaglutide 78.60 points， semaglutide 77.35 points，polyethylene glycol loxenatide 67.40 points， and exenatide microspheres 65.50 points， respectively. Dulaglutide had advantages in reducing blood sugar， arteriosclerotic cardiovascular disease， kidney benefits， and cost-effectiveness. Semaglutide had advantages in reducing blood sugar and weight loss， but its cost-effectiveness was lower than that of dulaglutide. Exenatide microspheres had advantages in the use of children， but its daily average treatment cost is the highest. Polyethylene glycol loxenatide needed further clinical evidence.CONCLUSIONSFour GLP-1RA weekly preparations all have high pharmaceutical comprehensive scores. Dulaglutide and semaglutide may have more comprehensive pharmaceutical value among them， while the use of exenatide microspheres for children is unique.关键词：Mini health technology assessment;semaglutide;dulaglutide;exenatide microspheres;polyethylene glycol loxenatide- 20

发布时间：2023-07-24 - 摘要：As an adjuvant alternative therapy， phototherapy is widely used for early diagnosis and late treatment of breast cancer due to its non-invasive treatment characteristics. But the application of phototherapeutic agents has been limited in the clinic due to poor hydrophobicity and tissue targeting， low photostability， and obvious toxic side effects in vivo. With the development of nanotechnology， new composite nano-phototherapy agents have emerged. This paper summarizes the latest developments and findings of new composite nano-phototherapy agents for phototherapy in the field of breast cancer treatment in the past 5 years. With the development of multifunctional nanomaterials in the field of breast cancer imaging diagnosis and treatment， the modified phototherapy agent achieved further development respectively from improving light response to improve the light thermal conversion or increasing the generation of reactive oxygen species， targeting tumor microenvironment， immune cells and cancer cell surface receptors to achieve drug controllable response release， using biomimetic materials and endogenous substances to improve biocompatibility. Although phototherapeutic agents exhibit high cell-killing rates in the treatment of metastatic breast cancer models and effectively inhibit their recurrence and metastasis， problems remain regarding the safety and compatibility of synergistic therapy. Future studies can not only improve the existing effects of phototherapeutic agents， but also develop oral drugs with more convenient routes based on immunotherapy to amplify the immune response and resist breast cancer through multiple routes.关键词：nanomaterials;photothermal therapy;photodynamic therapy;breast cancer

发布时间：2023-07-24 - 摘要：Lung cancer is mainly non-small cell lung cancer （NSCLC）. NSCLC is often associated with epidermal growth factor receptor （EGFR） gene mutations. Currently， epidermal growth factor receptor tyrosine kinase inhibitors （EGFR-TKI） are the preferred first-line treatment option for EGFR-mutated NSCLC. Furmonertinib is the second third-generation EGFR-TKI marketed in China， which is developed independently by China. In this review， it is found that furmonertinib has dual activity， strong tumor suppression， high selectivity， and high safety profile， and is effective in the treatment of EGFR-sensitive mutation， EGFR exon 20 T790M resistance mutation， EGFR exon 20 insertion mutation， and central nervous system metastasis NSCLC， and its relevant clinical trials are only enrolled in Chinese patients， which is more guidance for Chinese NSCLC patients in China.关键词：epidermal growth factor receptor;tyrosine kinase inhibitors;non-small cell lung cancer;mutations;efficacy;safety
