ObjectiveTo address the limitations of the current quality standard for Polygalae Radix(PR), which relies on a single component for quality assessment and struggles to holistically control its intrinsic quality, by constructing a comprehensive quality evaluation system integrating "macro-characterization of chemical profile, synchronous quantification of multiple index components, and quantitative analysis of multi-components by single marker(QAMS) for key component groups". This study aims to facilitate the scientific revision of the quality standard for PR. MethodsHigh performance liquid chromatography(HPLC) characteristic chromatograms were established for 11 batches of PR medicinal materials(YZ), 10 batches of PR decoction pieces(YP), and 10 batches of licorice-processed PR decoction pieces(ZYZ), followed by similarity evaluation and identification of common peaks. HPLC-QAMS was developed for xanthones(sibiricaxanthone B, polygalaxanthone Ⅺ, polygalaxanthone Ⅲ) in the characteristic chromatograms. Simultaneously, the external standard method(ESM) was used to determine the contents of the corresponding xanthones and 3,6'-disinapoyl sucrose in YZ, YP, and ZYZ, followed by multivariate statistical analysis and Spearman correlation analysis. ResultsThe similarity between the characteristic chromatograms of 31 batches of PR samples and the reference chromatogram was>0.9. A total of 13 common peaks were identified, and 10 of these peaks were characterized through reference standard comparison. The successfully constructed QAMS method showed that the relative correction factors(RCFs) of sibiricaxanthone B and polygalaxanthone Ⅺ to polygalaxanthone Ⅲ were 0.76 and 0.88, and their relative retention times(RRTs) were 0.85 and 0.97, respectively. The results calculated by the QAMS method showed no significant difference from those obtained by the ESM. According to the limit standard for polygalaxanthone Ⅲ in the 2020 edition of the Pharmacopoeia of the People's Republic of China(hereinafter referred to as the Chinese Pharmacopoeia), the pass rate of 31 batches of samples was only 19.35%. Multivariate statistical analysis indicated certain compositional differences between different batches of YZ and YP, as well as between YP and ZYZ, with 3,6'-disinapoyl sucrose identified as the main differentiating component. Furthermore, correlation analysis revealed that the content of polygalaxanthone Ⅲ was positively correlated with the contents of sibiricaxanthone B and polygalaxanthone Ⅺ, but showed no association with the content of 3,6'-disinapoyl sucrose. ConclusionIt is recommended that the content limit for polygalaxanthone Ⅲ in YZ,YP and ZYZ be revised to not less than 0.07%, or the total content of polygalaxanthone Ⅲ, sibiricaxanthone B and polygalaxanthone Ⅺ be not less than 0.18%. The newly established triple quality control model of "holistic control via characteristic chromatograms, precise quantification of oligosaccharide esters, and efficient detection of xanthones by QAMS" provides a systematic and precise solution for quality evaluation of PR and similar Chinese herbal medicines.

OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics ( 2026 edition ) in response to the challenges faced by such clinics in China, including uneven development, large discrepancies in service specifications, insufficient patient awareness, and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association, the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association, and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association, a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research, current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections: definition and connotation of pharmacist-managed clinics, establishment requirements, implementation and management, post competency, and practical research. Firstly, the definition and connotation included three operational forms of pharmacist-managed clinics (independent mode, physician-pharmacist joint mode, and online pharmacist-managed clinic mode) and classified service modes (specialty-specific, drug-specific, and disease-specific pharmacist-managed clinics). The establishment requirements were further refined, covering system construction (pharmaceutical service management system, quality control and assessment mechanism), personnel qualifications (professional credentials, continuing education and professional training, etc), service recipients, as well as service venues and facilities. Subsequently, the implementation and management of pharmacist-managed clinics were proposed, involving service procedures, intervention measures, documentation and records, patient education and follow-up, humanistic care, as well as risk management and quality control. Finally, post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics, as well as the suggestions on teaching methods; practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment, management, teaching, and research, fill the guideline gap in this field, and can promote the high-quality development of pharmacist-managed clinics.

ObjectiveTo identify the characteristic exhaled volatile organic compounds (VOCs) associated with postoperative pulmonary complications (PPCs) in patients after abdominal surgery. MethodsThis study prospectively enrolled 76 patients with tracheal intubation who were transferred to intensive care unit (ICU) after abdominal surgery at Peking University People's Hospital between December 10, 2022 and June 30, 2023. The patients' basic information was collected during their perioperative period, and their exhaled VOCs were collected within 24 hours after their admission to the ICU, and then analyzed by gas chromatography and mass spectrometry (GC-MS). According to whether PPCs occurred 24 hours after surgery, the patients were divided into PPCs group (n=44) and non-PPCs group (n=32), and the differences of VOCs were compared between the two groups. Lasso regression analysis was used to screen the valuable variables of VOCs, and Logistics regression analysis to determine the characteristic VOCs associated with the occurrence of PPCs. ResultsAmong the 76 patients, 44 had PPCs and 32 had no PPCs. Lasso regression analysis screened 4 PPCs-related compounds from exhaled VOCs of two groups for further analysis and Logistics regression analysis showed that the increase of 1-Hexadecanol content in exhaled breath was significantly correlated with the occurrence of PPCs (OR: 1.000, P=0.002). ConclusionThis study indicated that the increased content of 1-Hexadecanol in patients' exhaled breath after abdominal surgery may be associated with the occurrence of PPCs.

BackgroundAs a high prevalence disorder, schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently, the dominant vocational training model in China follows a paternalistic, clinician-led decision-making approach. Although it improves patients' social function to some extent, it undermines their autonomy and treatment adherence. Therefore, it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients, so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases, tenth edition (ICD-10) criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric, Chengdu. Participants were randomly allocated into the research group (n=34) and the control group (n=34) using a random number table method. Both groups received routine rehabilitation training, while the research group received shared decision-making oriented vocational training for 12 weeks, 2 times a week for 2 hours each time. Before and at the 4th and 12th week of intervention, two groups were evaluated by General Self-Efficacy Scale (GSES), Stigma Scale for Mental Illness (SSMI), Scale of Social function of Psychosis Inpatients (SSFPI) and Inpatient Psychiatric Rehabilitation Outcome Scale (IPROS). ResultsA total of 63 participants completed the study, with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES, SSMI, SSFPI and IPROS scores (F=20.451, 16.022; 26.193, 12.944; 23.957, 5.023; 11.776, 3.985, P<0.05 or 0.01), while no significant group effects were observed (F=0.188, 0.742, 1.878, 0.474, P>0.05). At the 12th week of intervention, there were statistically significant differences in GSES, SSMI, SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. [Funded by 2023 Chengdu Medical Research Project (number, 2023468)]

OBJECTIVE To assess the cost-effectiveness of durvalumab combined with chemotherapy as a first-line treatment for advanced biliary tract cancer from the perspective of the Chinese healthcare system. METHODS Using data from the TOPAZ-1 clinical trial, a three-state Markov model comprising progression-free survival (PFS), progressive disease (PD) and death was developed, with a cycle length of 21 days and a 10-year time horizon. Patients in the observation group received durvalumab in combination with gemcitabine and cisplatin, whereas those in the control group received placebo plus the same chemotherapy regimen. The evaluation indexes were quality-adjusted life year (QALY) and the incremental cost-effectiveness ratio (ICER). The willingness-to-pay (WTP) threshold was set at three times the 2024 Chinese per capita gross domestic product (GDP) (287 247 yuan/QALY). The sensitivity analyses, along with scenario analyses, were performed. RESULTS In the base-case analysis, the ICER of observation group compared to control group was 1 166 344.46 yuan/QALY, far exceeding the WTP threshold, indicating that the regimen was not cost-effective. One-way sensitivity analysis identified the PD state utility, discount rate, cost of durvalumab, and PFS state utility as the main drivers of ICER variation. Probabilistic sensitivity analysis showed that, at the above WTP threshold, the probability of the acceeptance of this regimen was 0, further supporting the robustness of the base-case findings. In the scenario analysis, inclusion of a patient assistance program reduced the ICER to 235 885.16 yuan/ QALY, below the above WTP threshold, suggesting cost-effectiveness under this assistance program. However, when applying a regional WTP threshold set at three times the per capita GDP (158 475 yuan/QALY) of Gansu Province (the province with the lowest GDP in China in 2024), the ICER remained above the threshold, indicating that the regimen was not cost-effective at the regional level. CONCLUSIONS At current pricing, durvalumab plus chemotherapy as a first-line treatment for advanced biliary tract cancer is not cost-effective in China. Although the introduction of a patient assistance program can substantially reduce the ICER and achieve cost-effectiveness at a WTP threshold set at three times the 2024 per capita GDP of China, due to limited affordability in low-income areas, the program remains not cost-effective.

OBJECTIVE:
To evaluate the effects of acupuncture at Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) on pain, anxiety, intrapartum blood loss, labor stage, and neonatal outcomes in primiparas.
METHODS:
One hundred primiparas were randomly divided into an acupuncture group (50 cases, 1 case was eliminated) and a control group (50 cases). The conventional obstetrical nursing was given in the control group. On the basis of the intervention in the control group, acupuncture was applied at bilateral Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) in the acupuncture group. The delivery mode and labor stage, the scores of visual analogue scale (VAS) for uterine contraction pain and Hamilton anxiety scale (HAMA) before and after acupuncture, the intrapartum/postpartum blood loss and massive hemorrhage, as well as the neonatal Apgar score after 1, 5, and 10 min of birth, were compared in the two groups.
RESULTS:
The cesarean section rate was 4.1% (2/49) in the acupuncture group, which was superior to 10.0% (5/50) in the control group (P<0.05). In the acupuncture group, the time of latent phase of 2-cm cervical dilation, active phase, first and second stages of labor, and total labor stage was shorter than that in the control group (P<0.001), the intrapartum blood loss and massive hemorrhage rate were lower than those in the control group (P<0.001, P<0.05). After acupuncture, the VAS and HAMA scores were decreased compared with those before acupuncture in the acupuncture group (P<0.001), the VAS and HAMA scores were increased compared with those before acupuncture in the control group (P<0.001). In the acupuncture group, the VAS and HAMA scores after acupuncture were lower than those in the control group (P<0.001), the changes of the VAS and HAMA scores before and after acupuncture were larger than those in the control group (P<0.001). There were no statistical differences in neonatal Apgar scores between the two groups (P>0.05).
CONCLUSION
Acupuncture at Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) can effectively alleviate the pain and anxiety, shorten the labor stage, reduce the intrapartum blood loss and incidence rate of massive hemorrhage, and promote spontaneous delivery, thereby enhancing maternal comfort and safety in primiparas.

In February 2025, a local cluster outbreak caused by the D8 genotype Measles virus (MV) was first discovered in Henan Province. Epidemiological investigations and laboratory testing were conducted, including the collection of serum and throat swabs for MV IgM antibody and nucleic acid detection, virus isolation and genetic homology analysis. Measures such as close contact tracing, vaccination rate assessment and supplementary immunization activities were implemented, successfully preventing broader community transmission. A total of three cases were reported during the outbreak, including one imported-related adolescent and two secondary local adult cases. All cases presented with typical symptoms such as fever and rash. Both adult cases were complicated by pneumonia, with one case developing into severe pneumonia. MV genotyping showed that the two secondary cases were both the D8 genotype, with the viral sequences being completely homologous to the Kazakhstan strain. Among the close contacts, 98.2% were adults, and 142 individuals received emergency vaccination.
