The assessment indicator system was finally constructed for emergency management capacity of generic drug quality and safety， including 4 first-level indicators （quality risk early warning capabilities， emergency preparedness capabilities， response and disposal capabilities， and emergency recovery capabilities）， 11 second-level indicators （ability to monitor and early warn of quality risks in the development and production process of generic drugs， emergency organization mechanism guarantee， disposal and recovery， etc.） and 75 third-level indicators （risk monitoring of raw material quality of generic drugs， consistency evaluation of quality and efficacy of generic drugs， and monitoring of profit margin risks and hidden dangers of generic drugs， etc.）. Among them， the weight of generic drug quality risk monitoring and early warning capacity was the highest among the first-level indicators （0.392 4）， the combined weight of generic drug R&D and production quality risk monitoring and early warning capacity was the highest among the second-level indicators （0.146 0）， and the combined weight of generic drug raw material quality risk monitoring was the highest among the third-level indicators （0.023 0）.CONCLUSIONSThe emergency management capacity assessment index system of generic drug quality and safety constructed in this study is hierarchical， reasonably weighted， and has a certain degree of credibility， and it can be used as an effective tool for the management and decision-making of generic drug quality and safety emergency management capacity assessment in the context of the normalization of centralized procurement.关键词：emergency response capacity evaluation;emergency management;assessment indicator system;national centralized drug volume-based procurement policy

RESULTS &CONCLUSIONSIn terms of adjustment methods， Japan and South Korea were similar to China. For excessive drugs， the reduction rate of drugs was calculated based on the situation of excess and adjustments were implemented； however， there were differences in the specific adjustment criteria and formulas. Japan and South Korea adopted a linear price reduction approach for drugs with significant oversupply， while China adopted a gradient price reduction approach for drugs with both current and expected oversupply. The results of the comparative analysis show that China has initially established simple renewal mechanisms that are in line with the national conditions and the actual medical insurance situation， and has taken some innovative measures， including considering the current and expected oversupply of drugs and introducing a halving mechanism in the adjustment formula. However， there are also certain shortcomings， such as a relatively single set of indicators for adjusting conditions and a too broad range of gradient price reduction in adjustment formulas， which fail to fully reflect the market-oriented mechanism of “volume for price”. It is recommended that China’s medical insurance department increase consideration of drug fund expenditures， refine the gradient price reduction range of adjustment formulas， increase policy preferences for special category drugs when adding new indications， and further improve the mechanism for simple renewal.关键词：simple renewal mechanism;medical insurance payment standards adjustment;medical insurance fund expenditures

Forty-eight rats with successful modeling were divided into model group （normal saline）， low-dose and high-dose FMN groups （20 and 40 mg/kg FMN）， and high-dose FMN+YAP inhibitor Verteporfin （VTPF） group （40 mg/kg FMN+10 mg/kg VTPF）， with 12 rats in each group. Another 12 rats were set as the normal group （normal saline）. They were given drug/normal saline， once a day， for 7 consecutive days. After the last administration， the disease activity index （DAI） of rats was calculated， and the colon length of rats in each group was measured. The pathological changes in the colon tissue of rats were observed. The levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6） and IL-10 in serum were detected， and the apoptosis of intestinal epithelial cells was detected. The expressions of Yes associated protein （YAP）， cleaved cysteine-containing aspartate proteolytic enzyme 3 （cleaved-caspase-3）， B-cell lymphoma-2 （Bcl-2） and Bcl-2 associated X protein （Bax） were detected in colon tissue of rats.RESULTSCompared with the normal group， DAI score， the levels of TNF-α and IL-6， the apoptotic rate of intestinal epithelial cells， and the expressions of cleaved-caspase-3 and Bax protein in the model group were increased greatly （P＜0.05）； the length of the colon was greatly decreased （P＜0.05）， and the serum level of IL-10 and the protein expressions of YAP and Bcl-2 were greatly reduced （P＜0.05）. The cell morphology of colon tissue was abnormal， with disordered arrangement and inflammatory cell infiltration. Compared with IBD group， the above indexes of rats were improved significantly in low-dose and high-dose FMN groups （P＜0.05）， in dose-dependent manner （P＜0.05）. VTPF significantly alleviated the effects of FMN on the above indexes of IBD rats （P＜0.05）.CONCLUSIONSFMN may promote the expression of YAP by inhibiting the Hippo/YAP signaling pathway， thereby inhibiting apoptosis of intestinal epithelial cells in IBD rats.关键词：Hippo/YAP signaling pathway;inflammatory bowel disease;intestinal epithelial cells;cell apoptosis

发布时间：2024-07-10 - 摘要：OBJECTIVETo mine adverse drug event （ADE） signals related to the pulmonary arterial hypertension （PAH） therapeutic drug macitentan， and to provide reference for safe clinical medication.METHODSMacitentan-related ADE reports were collected from the US FDA Adverse Event Reporting System （FAERS） database from the fourth quarter of 2013 to the third quarter of 2023. Data mining was conducted by using the reporting odds ratio （ROR）methodand the comprehensive standard method established by the UK Medicines and Healthcare Products Regulatory Agency （referred to as “MHRA method”） under the proportional imbalance approach. According to the systemic organ class （SOC） and preferred term （PT） stated in 26.0 edition of Medical Dictionary of Regulatory Activities， standardized coding of ADE names was performed， followed by the analysis of time to onset （TTO） and the Weibull shape parameter （WSP） test.RESULTSOverall， a total of 26 079 ADE reports were identified with macitentan as the primary suspect drug. These reports predominantly involved female patients （73.25%） and were concentrated in the age range of 18 to 65 years （42.39%）. The majority of reports originated from the US （84.42%）， with hospitalization or prolonged hospital stays （59.82%） being the most common in severe treatment outcome. A total of 269 ADE positive signals related to macitentan were identified. Among these， hypothyroidism， ADE related to renal injury such as the increase of serum creatinine and blood urea nitrogen， and ADE related to psychiatric disorders like apathy and despair were not included in the drug label. TTO analysis indicated that the majority of macitentan-related ADE signals occurred between 0-30 days after initial treatment （492 reports， 21.52%） and over 360 days （411 reports， 17.98%）. The results of WSP test showed that most of the top 20 reported ADE signals conformed to the characteristics of an early failure curve.CONCLUSIONSWhen clinically using macitentan in patients with PAH， attention should be given not only to the adverse reactions mentioned on the drug label but also to thyroid dysfunction， kidney dysfunction and mental disorder-related ADEs.关键词：pulmonary arterial hypertension;adverse drug event;signal mining;proportional imbalance method;rational drug use

发布时间：2024-07-10 - 摘要：OBJECTIVETo systematically evaluate the efficacy and safety of the four most common cell therapies， namely purified CD34+ （PCCs）， bone marrow mononuclear cells （BMMNCs）， bone marrow mesenchymal stem cells （BMMSCs） and peripheral blood mononuclear cells （PBMNCs） in the treatment of critical limb ischemia （CLI）.METHODSPubMed， Scopus， Embase， Cochrane Central Register of Controlled Trials （CENTRAL） and Web of Science databases were searched from the establishment of each database to June 2023 to collect randomized controlled trials （RCTs） comparing the efficacy and safety of four different cell therapies， namely PCCs， BMMNCs， BMMSCs and PBMNCs， with other cell therapies or standard therapy （ST） in the treatment of CLI. The outcomes indexes included amputation rate， ankle-brachial index （ABI）， transcutaneous oxygen partial pressure （TCPO2）， ulcer healing rate， pain-free walking distance （PFWD） and angiogenesis. After data extraction from clinical studies that met the inclusion criteria， the RoB 2.0 tool was used to assess the risk of bias， and Stata 15.0 software was used for statistical analysis.RESULTSMeta-analysis included 22 studies， involving 1 318 patients. The treatment groups involved 4 types of cell therapies， namely PCCs， BMMNCs， BMMSCs， and PBMNCs. Network meta-analysis showed that the amputation rates of the four cell therapies groups were lower than that of ST group， and only the difference in PBMNCs group was statistically significant（P＜0.05）. Four cell interventions were better than ST in improving ABI （P＜0.05）， and BMMNCs had the most significant effect on improving ABI. PBMNCs and BMMNCs groups had statistically significant differences in improving TCPO2， compared with ST group and BMMSCs group （P＜0.05）. Four cell interventions were better than ST in improving ulcer healing rate， among which BMMNCs group had no statistical difference with ST group （P＞0.05）； ulcer healing rates of the other three groups were higher than that of ST group （P＜0.05）， and those of PBMNCs and BMMSCs groups were significantly higher than that of BMMNCs group （P＜0.05）. BMMSCs group had a significantly better effect on improving the PFWD of patients than the ST group after transplantation， with statistical significance （P＜0.05）， but there was no significant difference in PBMNCs and BMMNCs groups compared with ST group （P＞0.05）. The three cell therapies of BMMSCs， BMMNCs and PBMNCs had a significantly better effect on angiogenesis than the ST group， and the BMMSCs group had a significantly better effect than the BMMNCs and PBMNCs groups， with statistical significance （P＜0.05）.CONCLUSIONSThe four cell therapies can improve the prognosis of CLI patients to varying degrees. PBMNCs show the lowest amputation rate after transplantation and have the most significant effect on improving TCPO2 and improving the ulcer healing rate. BMMNCs possess the most significant effect on improving ABI. BMMSCs represent obvious advantages in PFWD and angiogenesis.关键词：critical limb ischemia;peripheral arterial disease;mononuclear cells;mesenchymal stem cells;CD34+ cell;network meta-analysis

The quality of the included literature was evaluated and rated by Cochrane system evaluator manual 5.1.0 and GRADE tools. Meta-analysis and Egger’s test were carried out by using RevMan 5.4 and Stata 17.0 software.RESULTSOverall 24 RCTs were included in this study， involving 1 391 patients with NAFLD. Meta-analysis showed that compared with control group， the levels of alanine aminotransferase [MD＝－6.29， 95%CI （－9.35， －3.22）， P＜0.000 1]， aspartate aminotransferase [MD＝－4.89， 95%CI （－7.55， －2.23）， P＝0.000 3] and γ-glutamyl transferase [MD＝－4.87， 95%CI （－6.54， －3.20）， P＜0.000 01]， the liver stiffness measurement [MD＝－0.36， 95%CI （－0.48， －0.24）， P＜0.000 01]， the levels of triglycerides [MD＝－0.22， 95%CI （－0.27， －0.16）， P＜0.000 01]， total cholesterol [MD＝－0.34， 95%CI （－0.44， －0.25）， P＜0.000 01] and insulin resistance assessed by homeostasis model [MD＝－0.38， 95%CI （－0.63， －0.13）， P＝0.003] were all significantly decreased in the treatment group. However， there was no statistically significant difference of probiotics therapy in the levels of tumor necrosis factor-α [MD＝－0.41， 95%CI （－1.29， 0.48）， P＝0.37]， interleukin-6 [MD＝0.39， 95%CI （－0.10， 0.88）， P＝0.12]， high-sensitivity C-reactive protein [MD＝－0.30， 95%CI （－0.85， 0.25）， P＝0.28]， high-density lipoprotein cholesterol [MD＝0.03， 95%CI （－0.01， 0.06）， P＝0.10] and low-density lipoprotein cholesterol [MD＝－0.10， 95%CI （－0.27， 0.07）， P＝0.23] and body mass index [MD＝0.07， 95%CI （－0.26， 0.40）， P＝0.68]. Subgroup analysis based on different intervention measures showed that the levels of γ-glutamyl transferase， liver stiffness measurement， and homeostatic model assessment of insulin resistance in the synbiotic group were not significantly improved compared to the control group， with consistent results for the remaining outcomes. Egger’s test results showed no publication bias.CONCLUSIONSThe probiotic therapy can regulate liver function indexes， liver stiffness measurement and insulin resistance levels in patients with NAFLD well.关键词：nonalcoholic fatty liver disease;safety;efficacy;meta-analysis

发布时间：2024-07-10 - 摘要：Microneedles can penetrate the skin barrier to deliver drugs without touching the nociceptive nerves， to effectively increase the efficiency of transdermal drug delivery and improve patient compliance. Exosomes have multiple physiological functions and good biocompatibility， and are natural nanoscale drug carriers. This paper reviews the pathways and advantages of exosomes combined with microneedles for the treatment of diseases， and describes the current research status of exosome microneedle drug delivery system in various diseases. Exosome microneedles can be divided into two categories： （1） exosomes as therapeutic agents， their unique physiological origin can effectively avoid the toxicity and immunogenicity of conventional drugs and other problems； combined with microneedles directly in the specific medication site can greatly improve the metabolic consumption of oral drug delivery and patient compliance of injection drug delivery. （2） Exosomes as drug carriers， their natural vesicle structure and endogenous characteristics can protect the metabolism of foreign drugs in the body and enhance the targeting； combined with microneedles can effectively solve the problem of transdermal delivery of drugs with high efficacy but poor stability. Exosome microneedle drug delivery system is still in the laboratory stage， but it has shown great development prospects in repairing spinal cord injury， promoting diabetic ulcer wound healing， germinating， intervening myocardial infraction， relieving chronic pain and other diseases.关键词：exosome;percutaneous administration;drug loading system

发布时间：2024-07-10 - 摘要：Ruxolitinib， a small molecule inhibitor， selectively targets Janus kinase （JAK） by competitively binding to adenosine triphosphate on the catalytic site of the JAK1 and JAK2 domain， thereby inhibiting JAK activation and signal transducer and activator of transcription （STAT） phosphorylation and prevents the expressions of the JAK-STAT signaling pathway. Oral ruxolitinib has demonstrated promising efficacy for myelofibrosis and polycythemia vera. The topical Ruxolitinib cream， approved by the US FDA as the first non-segmental vitiligo home treatment drug， is set to be launched in domestic medical pioneer areas in August 2023 and is expected to bring about a breakthrough in the treatment of vitiligo. Clinical cases have also shown that Ruxolitinib cream has significant curative effects on atopic dermatitis， alopecia areata， and other conditions， indicating great application prospects.关键词：JAK-STAT signaling pathway;JAK inhibitors;myelofibrosis;polycythemia vera;vitiligo;skin diseases
