OBJECTIVE To analyze the development history， current status， and major challenges of central （cloud） pharmacies within China’s close-knit county-level medical communities， and to provide references for improving the overall effectiveness of the primary-level pharmaceutical supply and support system.METHODS Policy documents and practical case data related to central （cloud） pharmacies in county-level medical communities from 31 provinces （autonomous regions and municipalities） in China were collected. A qualitative approach combining policy text analysis and comparative case analysis was employed to longitudinally trace and cross-sectionally compare the development history and current status of central （cloud） pharmacies， identify existing problems， and propose targeted recommendations. RESULTS &CONCLUSIONS The development of central （cloud） pharmacies in China has undergone three stages： initial exploration， pilot expansion and mechanism deepening， and high-level promotion with local responses. While adhering to national policy directives， various regions have conducted diverse explorations in organizational and legal forms， management models， and institutional frameworks. However， several challenges remain， including insufficient policy guidance， an imperfect mechanism for drug coordination and supply security， weaknesses in hardware infrastructure and information technology development， and the need to strengthen statistical monitoring and outcome evaluation systems. It is recommended that the construction of central （cloud） pharmacies should be oriented toward achieving their fundamental functions， improve the institutional framework， adopt differentiated construction models tailored to local conditions， enhance the coordinated drug supply and support system， strengthen information technology infrastructure and professional capacity building， unify evaluation standards， and improve performance assessment mechanisms， so as to elevate the overall effectiveness of the primary-level pharmaceutical supply and support system.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Premature ovarian insufficiency(POI),also known as premature ovarian failure(POF),is one of the major causes of female infertility.Its incidence has been increasing year by year,seriously af-fecting women's reproductive health and becoming an increasingly serious public health problem world-wide.The pathogenesis of POI is complex and may be related to genetic,immune and environmental fac-tors,but in recent years,oxidative stress(OS)has received widespread attention as a key factor that can affect the function of ovarian granulosa cells(GCs),which can lead to the occurrence of POI.Reactive oxygen species(ROS)regulate the proliferation,survival and apoptosis of GCs through multiple signaling pathways,such as PI3K-Akt,MAPK,TGF-β/Smad,Notch,etc.AMPK and mitochondrial autophagy play important roles in attenuating the ROS damage and protecting the ovarian function.Excessive ROS disrupts the autophagy and lysosomal functions,leading to the accumulation of intracellular waste prod-ucts,thus affecting the physiological function and endocrine stability of GCs.In addition,OS can in-crease the risk of POI by affecting hormone synthesis and disrupting the function of GCs,leading to an imbalance in estrogen and progesterone levels.Herein we review the mechanism of OS in POI,explore how OS affects ovarian decline through the regulation of signaling pathways and cellular functions,and provide a theoretical basis for the clinical treatment of POI,which in turn provides new research ideas for its early diagnosis and prevention.

Objective:To explore the association between the use of tetracyclines during pregnancy and congenital malformations, with the aim of providing evidence-based guidance for the rational use of antibiotics during pregnancy.Methods:Data from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) and the Canada Vigilance Adverse Reaction (CVAR) database from January 2015 to September 2024 were collected. Five methods including Tree-based scan statistic (TreeScan), proportional reporting ratio (PRR), reporting odds ratio (ROR), the UK Medicines and Healthcare Products Regulatory Agency (MHRA) comprehensive standard, and the Bayesian confidence propagation neural network (BCPNN) were used to detect signals of risk for congenital malformations in offspring following maternal use of tetracyclines during pregnancy. A signal that met the threshold criteria of all above 5 methods was considered as a risk signal. Based on population-based cohort of the drug exposures and adverse pregnancy outcomes (DEEP) data from January 2013 to December 2021 in Xiamen City, propensity score matching (PSM)-based Poisson regression was applied to evaluate the association between the first-trimester tetracyclines exposure and congenital malformations in offspring. Adjusted relative risk (a RR) and its 95% confidence interval ( CI) were calculated. Sensitivity analysis was conducted to validate the reliability of the results. Results:A total of 304 098 reports of adverse events during pregnancy were obtained from the FAERS and CVAR databases. Among them, 5 028 reports were related to tetracyclines, including 1 026 reports of congenital malformations in offspring, involving congenital malformations of musculoskeletal system, other digestive system, and other congenital malformations. Signal detection results suggested that tetracyclines may be a risk signal for above congenital malformations in offspring. The DEEP data included 411 936 pregnant women. After PSM, 240 pregnant women exposed to tetracyclines were included. The results showed no significant association between the first-trimester tetracyclines exposure and congenital malformations in offspring (a RR=0.75, 95% CI: 0.26-2.17), sensitivity analysis also showed no correlation. Conclusions:Data mining from the FAERS and CVAR databases suggests a potential association between tetracyclines use during pregnancy and congenital malformations in offspring. However, the DEEP data study shows no significant correlation.

Objective To compare the value of transvaginal ultrasound, 3.0T magnetic resonance imaging (MRI) scanning alone and in combination for diagnosis of ectopic pregnancy, so as to provide insights into early screening of ectopic pregnancy. Methods This study enrolled a total of 130 patients with suspected ectopic pregnancy admitted to Dachuan People’s Hospital in Dazhou City, Sichuan Province, China between February 2019 and December 2022. All patients underwent transvaginal ultrasound examination and 3.0T MRI scanning. The consistency of transvaginal ultrasound and 3.0T MRI with clinical diagnostic results was evaluated with surgical pathology or clinical follow-up results as the golden standards. The sensitivity, specificity, and accuracy of transvaginal ultrasound and 3.0T MRI, alone and in combination, were compared for diagnosis of ectopic pregnancy. Results Of the 130 patients with suspected ectopic pregnancy, 108 cases were confirmed with ectopic pregnancy by surgical pathology, and 22 cases were confirmed without ectopic pregnancy by clinical follow-up. The sensitivity, specificity, and accuracy of transvaginal ultrasound were 85.19% (92/108), 54.55% (12/22), and 80.00% (104/130), respectively, with 0.358 consistency with clinical diagnostic results. The sensitivity, specificity, and accuracy of 3.0T MRI were 92.59% (100/108), 81.81% (18/22), and 90.77% (118/130), respectively, with 0.694 consistency with clinical diagnostic results. The sensitivity, specificity, and accuracy of transvaginal ultrasound combined with 3.0T MRI were 98.15% (106/108), 72.73% (16/22), and 93.85% (122/130), respectively, with 0.764 consistency with clinical diagnostic results. In addition, the sensitivity and accuracy of transvaginal ultrasound combined with 3.0T MRI were significantly higher than transvaginal ultrasound alone for diagnosis of ectopic pregnancy (χ² = 11.88 and 10.96, both P < 0.01). Conclusion Transvaginal ultrasound combined with 3.0T MRI may provide more diagnostic information for ectopic pregnancy, and is highly consistent with the clinical diagnostic results. In addition, transvaginal ultrasound combined with 3.0T MRI improves the diagnostic sensitivity and accuracy for ectopic pregnancy than transvaginal ultrasound alone.

Objective:To evaluate the effect of low-dose esketamine for postoperative analgesia on the postoperative depression in patients with gastrointestinal tumors.Methods:This study was a prospective randomized controlled trial. Eighty patients, aged 18-64 yr, with a body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective radical resection of the gastrointestinal tumor under general anesthesia from June to November 2023 in our hospital, were divided into 2 groups ( n=40 each) using a random number table method: esketamine group (group E) and control group (group C). Each patient received postoperative patient-controlled intravenous analgesia(PCIA). The PCIA solution in group E contained esketamine 0.5 mg/kg, dezocine 0.5 mg/kg, dexmetomidine 1.5 μg/kg and flurbiprofen ester 100 mg in 100 ml of normal saline. The PCIA solution in group C contained dezocine 0.5 mg/kg, dexmetomidine 1.5 μg/kg and flurbiprofen ester 100 mg in 100 ml of normal saline. The Hospital Anxiety and Depression Scale (HADS) was used to assess the patients′ anxiety and depression at 1 day before operation (T 0) and 2 days after operation (T 1). The Quality of Recovery-15 scale was used to evaluate the early postoperative recovery quality. Visual analog scale scores, the pressing times of patient-controlled analgesia and the number of rescue analgesia were recorded within 2 days after operation. The occurrence of drug-related adverse reactions was also recorded. Results:Seventy-eight patients were finally included, with 39 cases in group E and 39 cases in group C. Compared with group C, the postoperative HADS-depression scale score and incidence of depression were significantly decreased, the Quality of Recovery-15 scale score was increased, the visual analog scale scores were decreased ( P<0.05), and no significant changes were found in the postoperative HADS-anxiety scale score and incidence of anxiety, the pressing times of patient-controlled analgesia and the number of rescue analgesia in group E ( P>0.05). Visual hallucination was found at 1 day after operation in one patient and relieved at 2 days after operation in group E. There was no significant difference in the incidence of postoperative dizziness, nausea and vomiting between the two groups ( P>0.05). Conclusions:Postoperative analgesia with 0.5 mg/kg esketamine can alleviate postoperative depressive symptoms, enhance the efficacy of analgesia and improve the early postoperative recovery quality in patients with gastrointestinal tumors.
