Objective To analyze a case of violations by an occupational medical examination (OME) institution and to explore the key control points for the supervision and management of OME institutions, as well as the core role of quality assessment in this context. Methods An OME institution suspected of illegal activities was used as the study subject. Retrospective analysis was conducted. Clues of suspected violations were identified by an on-site quality assessment. After investigation and verification by the local health authorities, legal action was taken against the institution for its violations. Results During an on-site quality assessment, the Guangdong Province OME quality control expert group discovered that the OME institution violated regulations, including unqualified personnel file, exceeding the scope of services category, issuing false reports, failing to report suspected occupational diseases on time, and failing to notify workers about suspected occupational diseases as required. The evidence was then submitted to the Guangdong Province OME Quality Control Center, which subsequently forwarded the case to local health administration department for filing and investigation. After the investigation, penalties were imposed on the OME institution for its illegal activities. Conclusion The key supervision and inspection points in the quality assessment of OME institutions include personnel file configuration, the quality control management system and its implementation, the quality of OME reports, and information reporting. Quality assessment plays a pivotal role in ensuring the legal and compliant practice of OME institutions, safeguarding the health rights and interests of workers, and enhancing the overall standard of the OME industry.

OBJECTIVE To systematically evaluate the methodological quality of the postoperative chemotherapy guidelines/ consensuses for ovarian epithelial tumor. METHODS A search was conducted across databases including PubMed, Embase, Web of Science, CBM, VIP, Chinese Medical Journal Data, Wanfang Data, and CNKI, as well as the official websites of GIN, NICE, Medlive, AHRQ, CSCO, ASCO, and NCCN. The search period was from the establishment of the databases/websites to March 10, 2025. The quality of the included guidelines/consensus was evaluated by using the AGREE-Ⅱ tool. RESULTS A total of 16 guidelines/consensuses were included. The domain scores of AGREE-Ⅱ evaluation were as follows: scope and purpose of 85.07%, participants of 47.92%, rigor of development of 57.49%, clarity of presentation of 88.02%, applicability of 8.20%, and independence of 53.39%. Among them, 14 were recommended at grade B and 2 were recommended at grade C. The subgroup analysis by different countries/regions and different types of studies showed that the scores for participants, rigor of development, and independence of the guidelines/consensuses in China were significantly lower than foreign countries (P<0.05); the scores for participants and rigor of development of the guidelines were significantly higher than consensuses (P<0.05). The guideline/ consensus recommendation results indicated that grade B guidelines/consensus recommend platinum-based combination chemotherapy as the preferred adjuvant chemotherapy regimen for stage Ⅰ high-grade serous carcinoma patients;platinum-based combination chemotherapy±bevacizumab was recommended as the preferred adjuvant chemotherapy regimen for stage Ⅱ-Ⅳ high- grade serous carcinoma patients and for platinum-sensitive recurrent high-grade serous carcinoma patients; non-platinum single- agent chemotherapy±bevacizumab was recommended as the preferred chemotherapy regimen for platinum-resistant recurrent high- grade serous carcinoma patients. CONCLUSIONS The overall quality of postoperative chemotherapy guidelines/consensuses for ovarian epithelial tumor is not high. The methodological quality of guidelines/consensuses in China is still lagging behind that of foreign countries. The recommendations differ from those in foreign countries. It is recommended to improve the aspects of participants, rigor of development, and independence, to recommend treatment plans based on the different stages of ovarian cancer, and develop guidelines/consensuses that align with China’s national conditions.

OBJECTIVE:
To reveal the gap between the evidence of systematic reviews (SRs) and clinical concerns by systematically summarizing the evidence on acupuncture and moxibustion for frozen shoulder and investigating the concerns and needs of clinicians in treatment with acupuncture and moxibustion for this disease.
METHODS:
The articles of SR and Meta-analysis on acupuncture and moxibustion for frozen shoulder were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library, starting from the inception of each database up to December 31st, 2022. Two researchers screened the articles and extracted data independently. Using AMSTAR-2, the methodological quality of the included studies was evaluated. Based on systematic reviews and expert discussion, a questionnaire on clinical concerns of acupuncture and moxibustion for frozen shoulder was developed and distributed to clinicians. The discrepancies between the evidence and clinical concerns were compared from 5 dimensions, including population, interventions, control measures, outcome indicators and review time points.
RESULTS:
The evidence gaps existed between SRs and clinical concerns. In the existing studies, the needs of personalized treatment were not fully considered in terms of different syndromes/patterns of frozen shoulder and stages of illness, the outcome indicators were not employed properly, the time for outcome measurement was vague, the control groups were set up outside of standardization, and the methodological quality was lower.
CONCLUSION
It is suggested that future studies should improve the quality of methodology, lay more consideration to different patient groups, optimize outcome indicators and standardize the setting of control groups, so as to better meet the needs of patients and achieve the best match between evidence and clinicians' needs.

The pharmaceutical industry faces challenges in quality digitization for complex multi-stage processes, especially in small-sample systems. Here, an intelligent quality prediction and diagnostic (IQPD) framework was developed and applied to Tong Ren Tang's Niuhuang Qingxin Pills, utilizing four years of data collected from four production units, covering the entire process from raw materials to finished products. In this framework, a novel path-enhanced double ensemble quality prediction model (PeDGAT) is proposed, which combines a graph attention network and path information to encode inter-unit long-range and sequential dependencies. Additionally, the double ensemble strategy enhances model stability in small samples. Compared to global traditional models, PeDGAT achieves state-of-the-art results, with an average improvement of 13.18% and 87.67% in prediction accuracy and stability on three indicators. Additionally, a more in-depth diagnostic model leveraging grey correlation analysis and expert knowledge reduces reliance on large samples, offering a panoramic view of attribute relationships across units and improving process transparency. Finally, the IQPD framework integrates into a Human-Cyber-Physical system, enabling faster decision-making and real-time quality adjustments for Tong Ren Tang's Niuhuang Qingxin Pills, a product with annual sales exceeding 100 million CNY. This facilitates the transition from experience-driven to data-driven manufacturing.

OBJECTIVES:
To investigate the effects of quercetin on cuproptosis and L-type calcium currents in the myocardium of diabetic rats.
METHODS:
Forty SD rats were randomized into control group and diabetic model groups. The rat models of diabetes mellitus (DM) induced by high-fat and high-sugar diet combined with streptozotocin (STZ) injection were further divided into DM model group, quercetin treatment group, and empagliflozin treatment group (n=10). Blood glucose and body weight were measured every other week, and cardiac function of the rats was evaluated using echocardiography. HE staining, Sirius red staining, and wheat germ agglutinin (WGA) analysis were used to observe the changes in myocardial histomorphology, and serum copper levels and myocardial FDX1 expression were detected. In cultured rat cardiomyocyte H9c2 cells with high-glucose exposure, the effects of quercetin and elesclomol, alone or in combination, on intracellular CK-MB and LDH levels and FDX1 expression were assessed, and the changes in L-type calcium currents were analyzed using patch-clamp technique.
RESULTS:
The diabetic rats exhibited elevated blood glucose, reduced body weight, impaired left ventricular function, increased serum copper levels and myocardial FDX1 expression, decreased L-type calcium currents, and prolonged action potential duration. Quercetin and empagliflozin treatment significantly lowered blood glucose, improved body weight, and restored cardiac function of the diabetic rats, and compared with empagliflozin, quercetin more effectively reduced serum copper levels, downregulated FDX1 expression, and enhanced myocardial L-type calcium currents in diabetic rats. In H9c2 cells, high glucose exposure significantly increased myocardial expressions of FDX1, CK-MB and LDH, which were effectively lowered by quercetin treatment; Elesclomol further elevated FDX1, CK-MB and LDH levels in the exposed cells, and these changes were not significantly affected by the application of quercetin.
CONCLUSIONS
Quercetin ameliorates myocardial injury in diabetic rats possibly by suppressing myocardial cuproptosis signaling and restoring L-type calcium channel activity.

Objective:To observe the efficacy and safety of combined lienal polypeptide injection therapy in the treatment of Mycoplasma pneumoniae pneumonia(MPP)in children aged 3 to 14 years old in multiple clinical centers.Methods:A randomized,controlled,multi-center clinical study design was adopted.A total of 240 hospitalized children aged 3 to 14 years old with MPP from 7 hospitals from September 1,2023 to January 31,2024 were included.According to the severity of pneumonia,they were divided into the mild MPP group with 80 cases and the severe MPP/refractory MPP(SMPP/RMPP)group with 160 cases,and then randomly divided into the control group and the experimental group at a ratio of 1 ∶1,using the random number table method.After screening,subjects entered a treatment period of 5 to 7 days.The control group was treated with azithromycin,while the experimental group was treated with azithromycin plus lienal polypeptide injection .The recovery of lung CT,length of hospital stay,duration of fever,cough score,whether mild cases developed into severe or refractory cases,duration of hormone use,use of intravenous immunoglobulin(IVIG),bronchoscopy treatment,and immune function were observed between the two groups to evaluate the efficacy of lienal polypeptide injection.Adverse events after medication,vital signs,blood routine,urine routine,liver function,myocardial enzymes,renal function,and electrocardiogram were observed to evaluate the safety. Results:A total of 231 subjects have completed the trial in the 7 hospitals,including 118 cases in the experimental group and 113 cases in the control group.Main observation index:the rate of lung CT aggravation in the experimental group was lower than that in the control group(2.6% vs 15.3%, P<0.01),and the difference was statistically significant.Secondary indexes:there were no statistically significant differences in the length of hospital stay,duration of fever,cough score,duration of hormone use,whether IVIG treatment was used,the number of bronchoscopy treatment cases,and immunoglobulin between the two groups(all P>0.05).However,the rate of cases of plastic bronchitis(PB)found under bronchoscopy in the experimental group was lower than that in the control group(0 vs 18.8%, P=0.03),and the difference was statistically significant.Among the mild MPP(72 cases),there were no statistically significant differences in the length of hospital stay,duration of fever,cough score,duration of hormone use,whether IVIG treatment was used,the number of bronchoscopy treatment cases,and the improvement rate of lung CT between the two groups(all P>0.05).However,compared with the control group,the rate of cases developing into SMPP/RMPP in the experimental group was less(24.3% vs 48.6%, P=0.03),and the difference in IgG before and after treatment was small[0.53(-0.04,1.18)g/L vs 1.33(0.48,2.25)g/L, P=0.01].Among the SMPP/RMPP cases(159 cases),the rate of cases of PB found under bronchoscopy in the experimental group was less than that in the control group(0 vs 20%, P=0.04),and the rate of cases with aggravated lung CT in the experimental group was less than that in the control group(1.3% vs 19.5%, P<0.01),and the improvement rate of lung CT in the experimental group was higher than that in the control group(88.8% vs 75.3%, P=0.03),with statistically significant differences.There were no statistically significant differences in the length of hospital stay,duration of fever,cough score,duration of hormone use,whether IVIG treatment was used,the number of bronchoscopy treatment cases,and immunoglobulin between the two groups(all P>0.05).Two cases in the experimental group developed rashes,which improved after the drug was discontinued.There were no serious adverse reactions such as abnormal vital signs like dyspnea and cyanosis due to the use of lienal polypeptide injection.There were no obvious changes in blood routine,liver function,myocardial enzymes,renal function,electrocardiogram,and urine routine values before and after medication compared with the baseline. Conclusion:The combined use of lienal polypeptide injection in the treatment of MPP in children can reduce the probability of the transformation from mild cases to SMPP/RMPP,reduce the rate of aggravation of the image findings,promote the absorption of lung inflammation,reduce the rate of PB found under bronchoscopy,and has good safety.

ObjectiveTo observe the effects of Coptidis Rhizoma-Fermentum Rubrum on non-alcoholic fatty liver disease (NAFLD) in mice and explore its possible mechanisms. MethodSixty male SPF C57BL/6J mice were randomly divided into six groups: control group, model group, low-, medium-, and high-dose Coptidis Rhizoma-Fermentum Rubrum group (0.75, 1.5, 3 g·kg-1), and metformin group (0.075 g·kg-1), with 10 mice in each group. NAFLD mouse models were induced by high-fat diet feeding for 24 weeks. The low, medium, and high-dose Coptidis Rhizoma-Fermentum Rubrum groups were administered corresponding doses of Coptidis Rhizoma-Fermentum Rubrum by gavage, while the control and model groups received an equivalent amount of saline for four weeks. Serum total cholesterol (TC), triglycerides (TG), free fatty acids (FFA), and liver function markers including alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured using an automatic biochemical analyzer. Hematoxylin-eosin (HE) and oil red O staining were used to detect liver lipid deposition, and Prussian blue staining was used to measure liver ferrous ion levels. Western blot was performed to detect the expression of key proteins in the nuclear factor erythroid-2-related factor 2 (Nrf2)-glutathione peroxidase 4 (GPX4) axis. ResultAfter 24 weeks of high-fat feeding, compared with the control group, the model group showed significant increases in body weight, liver weight and liver index, and serum lipid levels (P<0.01), as well as substantial hepatic lipid deposition with marked steatosis. Compared with the model group, Coptidis Rhizoma-Fermentum Rubrum intervention reduced body weight (P<0.01), liver weight and liver index (P<0.01), and serum lipid levels (P<0.05, P<0.01), improved liver function (P<0.01), and decreased hepatic lipid deposition, with the low-dose Coptidis Rhizoma-Fermentum Rubrum group showing the best effect. Western blot results showed that compared with those in the control group, the expression levels of Nrf2, heme oxygenase-1 (HO-1), kelch-like ECH-associated protein 1(Keap1), and GPX4 proteins in the model group were decreased (P<0.05, P<0.01). Compared with the model group, Coptidis Rhizoma-Fermentum Rubrum increased the expression levels of these proteins (P<0.05, P<0.01). ConclusionCoptidis Rhizoma-Fermentum Rubrum can alleviate fatty liver in mice, improve liver function, and reduce hepatic lipid deposition, possibly by regulating the Nrf2/GPX4 ferroptosis axis.

Objective:To explore the robust relationship between insomnia and type 2 diabetes mellitus by two-sample Mendelian randomization analysis to overcome confounding factors and reverse causality in observational studies.Methods:We identified strong,independent single nucleotide polymorphisms(SNPs)of insomnia from the most up to date genome wide association studies(GWAS)within European ancestors and applied them as instrumental variable to GWAS of type 2 diabetes mellitus.After excluding SNPs that were significantly associated with smoking,physical activity,alcohol consumption,educational attainment,obesity,or type 2 diabetes mellitus,we assessed the impact of insomnia on type 2 diabetes mellitus using inverse variance weighting(IVW)method.Weighted median and MR-Egger regression analysis were also conducted to test the robustness of the association.We calculated the F statistic of the selected SNPs to test the applicability of instrumental variable and F statistic over than ten indicated that there was little possibility of bias of weak instrumental variables.We further examined the existence of pleiotropy by testing whether the intercept term in MR-Egger regression was significantly different from ze-ro.In addition,the leave-one-out method was used for sensitivity analysis to verify the stability and relia-bility of the results.Results:We selected 248 SNPs independently associated with insomnia at the genome-wide level(P<5 ×10-8)as a preliminary candidate set of instrumental variables.After clum-ping based on the reference panel from 1000 Genome Project and removing the potential pleiotropic SNPs,a total of 167 SNPs associated with insomnia were included as final instrumental variables.The F statistic of this study was 39.74,which was in line with the relevance assumption of Mendelian randomi-zation.IVW method showed insomnia was associated with higher risk of type 2 diabetes mellitus that po-pulation with insomnia were 1.14 times more likely to develop type 2 diabetes mellitus than those without insomnia(95%CI:1.09-1.21,P<0.001).The weighted median estimator(WME)method and MR-Egger regression showed similar causal effect of insomnia on type 2 diabetes mellitus.And MR-Egger re-gression also showed that the effect was less likely to be triggered by pleiotropy.Sensitivity analyses pro-duced directionally similar estimates.Conclusion:Insomnia is a risk factor of type 2 diabetes mellitus,which has positively effects on type 2 diabetes mellitus.Our study provides further rationale for indivi-duals at risk for diabetes to keep healthy lifestyle.
