ObjectiveTo evaluate the efficacy and safety of Janus kinase （JAK） inhibitors combined with Chinese herbal medicine （CHM） in treating rheumatoid arthritis （RA）. MethodsClinical data from 169 RA patients were retrospectively collected. Among them， 71 cases received JAK inhibitors as the control group， while 98 cases received JAK inhibitors plus CHM as the observation group， both treated for 24 weeks. The rheumatoid factor （RF）， cyclic citic peptide antibody （anti-CCP）， erythrocyte sedimentation rate （ESR）， C-reactive protein （CRP）， and white blood cell count （WBC） were recorded before and after treatment. Databases including CNKI， Wanfang， VIP， PubMed and Web of Science were searched from inception till August 31st， 2025 for randomized controlled trials （RCTs） on the combined use of JAK inhibitors and CHM for RA. The methodological quality of the included studies was evaluated using the risk of bias assessment tool. Meta-analyses were performed for RF， anti-CCP， ESR， CRP， 28-joint disease activity score （DAS28）， overall clinical effective rate， and incidence of adverse events. Sensitivity analysis were also performed. ResultsThe retrospective study demonstrated that after treatment， ESR， CRP， and anti-CCP levels decreased in the observation group， while ESR and CRP levels decreased in the control group （P＜0.05）. Moreover， ESR and RF levels in the observation group were lower than those in the control group （P＜0.05）. A total of 9 RCTs involving 770 patients were included in the meta-analysis. The results indicated that the JAK inhibitors plus CHM group was superior to the JAK inhibitors group in reducing RF （MD=-8.97， 95%CI -15.01 to -2.94， P=0.004）， CRP （MD=-3.34， 95%CI -3.82 to -2.86， P＜0.001）， ESR （MD=-5.33， 95%CI -7.98 to -2.69， P＜0.001）， and DAS28 score （MD=-0.54， 95%CI -0.74 to -0.34， P＜0.001）， as well as in improving the overall clinical effective rate （OR=4.53， 95%CI 2.55 to 8.03， P＜0.001）. No statistically significant differences were observed between groups in anti-CCP levels （SMD=-2.08， 95%CI -4.41 to 0.24， P=0.080） or incidence of adverse events （OR=0.93， 95%CI 0.55 to 1.57， P=0.790）. ConclusionThe combination of JAK inhibitors and CHM demonstrates remarkable efficacy in treating RA， contributing to improved disease activity and reduced inflammatory markers with a favorable safety profile.

Recent research from the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) indicates that breast cancer is the most prevalent malignant tumor among women, posing a significant threat to women's health. Surgery remains the primary therapeutic modality for breast cancer. Recently, endoscopic and robotic breast surgical techniques have gained acceptance among both surgeons and patients. However, considerable variation exists in surgical approaches and outcomes. To standardize these techniques, facilitate their broader clinical adoption, and ultimately improve patient care, the Endoscopic-robotic Breast Surgery Clinical Trials Consortium (ErBSCTC) of China has developed this guideline. This document encompasses the technologies and instrumentation utilized in endoscopic and robotic breast surgery, surgical techniques, perioperative management, complication handling, long-term follow-up, and oncologic outcomes, aiming to provide evidence-based guidance for healthcare professionals involved in the prevention, diagnosis, and treatment of breast diseases.

Breast cancer is the most common malignant tumor among women in China, with surgery being one of the primary treatment modalities. Endoscopic/robotic breast surgery (ErBS) is gaining widespread acceptance among patients and surgeons alike due to its advantages of minimal invasiveness, superior cosmetic outcomes, and accelerated recovery. However, substantial heterogeneity currently exists across China regarding patient selection, standardized operative techniques, perioperative management, and complication handling, underscoring the urgent need for evidence-based consensus guidelines. To promote standardization and ensure consistent quality of ErBS, the Chinese Endoscopic-Robotic Breast Surgery Clinical Trials Consortium (CErBSCTC) has systematically reviewed the latest high-quality evidence and formulated the "Protocol for China Endoscopic and Robotic Breast Surgery Guidelines (2026 edition)", which outlines a comprehensive methodology for guideline development.

This guideline, presented in three parts, details the core aspects of endoscopic/robotic breast surgery, including its techniques, equipment, surgical procedures, perioperative management, complication treatment, long-term follow-up, and outcomes. Part one offered a comprehensive overview of indications for endoscopic and robotic breast surgery, intraoperative techniques, surgical instrument choices, and common endoscopic and robotic breast reconstruction procedures. This part will cover other endoscopic breast procedures beyond immediate breast reconstruction and include perioperative management strategies, to provide healthcare professionals involved in endoscopic and robotic breast surgery with systematic operational guidelines and clinical decision-making references.

Objective To investigate the causal relationship between metabolic syndrome and breast cancer by using a bidirectional two-sample Mendelian randomization (MR) approach. Methods Genome-wide association study (GWAS) summary statistics for metabolic syndrome and breast cancer were acquired from the Integrative Epidemiology Unit GWAS database and the GWAS Catalog, with populations encompassing the United States and East Asia. A bidirectional causal design was employed: a forward analysis with metabolic syndrome as the exposure and breast cancer as the outcome, followed by a reverse analysis wherein their roles were interchanged. The inverse-variance weighting (IVW) method was primarily used for effect estimation, supplemented by MR-Egger regression, the weighted median method, the simple mode method, and the weighted mode method. Instrument variable strength was screened using the F-statistic (F>10). Robustness of the results was assessed through heterogeneity tests, horizontal pleiotropy tests, forest plots, and leave-one-out sensitivity analyses. Results The IVW analysis indicated no significant causal relationship between metabolic syndrome and breast cancer (OR=1.00, 95%CI: 0.97-1.03), P>0.05). Sensitivity analyses yielded consistent results, suggesting the good robustness of the study findings. Conclusion This study found no evidence to support a causal relationship, either positive or negative, between metabolic syndrome and breast cancer.

Irritable bowel syndrome （IBS） is a functional bowel disorder characterized primarily by abdominal pain and altered defecation habits. In recent years， traditional Chinese medicine （TCM） has made progress in multiple aspects of IBS research and treatment， including syndrome distribution， development of TCM formulas， clinical efficacy evaluation， external therapies， and psychosocial regulation. However， it still faces challenges such as over-reliance on symptomatic manifestations rather than biomarkers for diagnostic criteria， and the lack of high-quality evidence-based data supporting the efficacy of TCM formulas in treating IBS. This paper proposed that TCM diagnosis and treatment of IBS should adhere to the strategy of integrating the holistic concept with syndrome differentiation and treatment， combining TCM external therapies such as acupuncture， moxibustion and acupoint application）， and emphasizing individualized diagnosis and treatment for psychosomatic abnormalities. Future research should integrate multi-omics technologies， artificial intelligence and other methods to deepen the understanding of the pathogenesis of IBS and the mechanisms of TCM formulas， so as to promote the standardization and internationalization of TCM in the diagnosis and treatment of IBS.

It is proposed that the pathogenesis of rheumatoid arthritis （RA） is centered on deficiency， dampness， and blood stasis， which interact with and evolve into one another during the onset and progression of the disease. The development of RA is closely associated with insufficiency of healthy qi and the interbinding of dampness and blood stasis. Accordingly， treatment emphasizes an integrated approach that combines tonifying deficiency， eliminating dampness， and resolving blood stasis， and is implemented in three main stages. In the initial stage， therapy focuses on supporting healthy qi， dispelling dampness， and relieving impediment， with modified Huangqi Guizhi Wuwu Decoction （黄芪桂枝五物汤） combined with Yiyiren Decoction （薏苡仁汤）. In the active stage， treatment aims to eliminate dampness， resolve blood stasis， and unblock the collaterals， using modified Wutou Decoction （乌头汤） or Guizhi Shaoyao Zhimu Decoction （桂枝芍药知母汤）. In the remission stage， therapy emphasizes strengthening the spleen and reple-nishing qi to prevent recurrence， with modified Shenling Baizhu Powder （参苓白术散） combined with Guipi Decoction （归脾汤）.

Objective: To analyze the epidemiological characteristics of hand, foot and mouth disease (HFMD) among children aged 0-9 years in Guangzhou, so as to provide reference basis for further exploring scientifically effective prevention and control measures. Methods: Reported cases of HFMD in children aged 0-9 years in Guangzhou City from 2013-2025 were selected from China disease prevention and control information system, and the incidence in different years was analyzed descriptively; the trends of the composition ratio and incidence in various age groups were analyzed by using the Joinpoint regression model, spatial autocorrelation analyses were performed at the district level, and the seasonal autoregressive integrated moving average model (SARIMA) was applied to predict annual incidence rate for 2026. Results: From 2013 to 2025, the average annual reported incidence rate of HFMD among children aged 0-9 years in Guangzhou was 2 513.98/100 000, showing a fluctuating trend. Peaks of incidence occurred from May to July and from September to October. The male to female ratio was 1.49∶1. The average annual incidence rate was 4 743.99/100 000 in the 0-1 years age group, 3 298.19/100 000 in the 2-5 years age group, and 544.22/ 100 000 in the 6-9 years age group. Joinpoint regression analysis showed a decreasing trend in the proportion of the 0-1 years age group (APC= -6.02 %, t =-3.77) and an increasing trend in the proportion of the 6-9 years age group (APC=16.39%, t =5.67) (both P < 0.05 ). No significant global spatial clustering was observed at the district level; however, local scattered clusters were identified in certain areas. Using the SARIMA(2,0,0)(2,0,0) 12 model, the predicted annual incidence rate of HFMD among children aged 0-9 years in Guangzhou in 2026 was 2 680.56/100 000. Conclusions From 2013 to 2025, the annual incidence rate of HFMD among children aged 0-9 years in Guangzhou exhibited a fluctuating trend; the highest incidence rate is observed in the 0-1 years age group, while the proportion of cases in the 6-9 years age group increase year by year;and local spatial clusters of abnormal distribution are identified. It is essential to enhance risk monitoring and health education in key populations and areas to mitigate the risk of infection in children.

ObjectiveTo compare the incidence of postoperative shivering between female patients undergoing gynecological and general surgery and to examine perioperative factors associated with postoperative shivering. MethodsThis retrospective study included 12 186 patients who underwent gynecological or general surgery between January 1， 2022， and March 15， 2024， of whom 10 884 female patients constituted the primary analysis population. Among the female patients， 1：1 nearest-neighbor propensity score matching was performed using a caliper of 0.02 on the raw propensity score scale， with exact matching on American Society of Anesthesiologists （ASA） physical status. After matching， the incidence of postoperative shivering was compared using the McNemar test. Conditional logistic regression stratified by matched pair was used to assess the associations of surgical categories and perioperative factors with postoperative shivering. ResultsBefore propensity score matching， the incidences of postoperative shivering were 2.98% （28/940） in the general surgery group and 4.94% （491/9 944） in the gynecological surgery group （P=0.007）. After matching， 881 matched pairs were obtained， and the absolute standardized mean differences （SMDs） for all covariates were < 0.10. The incidences of postoperative shivering were 3.06% （27/881） in the general surgery group and 4.99% （44/881） in the gynecological surgery group. The McNemar test without continuity correction yielded P=0.044， whereas the exact McNemar test showed a P value of 0.057. Unifactorial conditional logistic regression showed that gynecological surgery was associated with higher odds of postoperative shivering than general surgery ［odds ratio （OR）=1.63， 95% confidence interval （CI）： 1.01-2.63， P=0.046］. However， the association was not statistically significant in the multifactorial conditional logistic regression ［adjusted odds ratio （aOR）=1.62， 95%CI： 0.78-3.37， P=0.197］. Each 30-min increase in the duration of surgery was associated with 32% higher odds of postoperative shivering （aOR=1.32， 95%CI： 1.07-1.62， P=0.009）. Each 1 °C increase in the minimum intraoperative body temperature was associated with lower odds of postoperative shivering， although the association did not reach statistical significance （aOR=0.32， 95%CI： 0.10-1.02， P=0.053）. ConclusionAfter propensity score matching， the incidence of postoperative shivering was higher among female patients undergoing gynecological surgery than among those undergoing general surgery； however， neither the exact comparison nor the adjusted association reached statistical significance. A longer duration of surgery was associated with higher odds of postoperative shivering， whereas a higher minimum intraoperative body temperature may be associated with lower odds.

ObjectiveTo explore the clinical value of metagenomic next-generation sequencing（mNGS） in patients with sepsis admitted to the Emergency Intensive Care Unit（EICU），evaluate its role in guiding precision antimicrobial therapy， and to identify key factors influencing mNGS positivity and patient prognosis. MethodsThis retrospective study analyzed clinical data from 524 patients with sepsis admitted to the EICU of Sun Yat-sen Memorial Hospital， Sun Yat-sen University， from November 2020 to October 2024. The positive detection rate， pathogen spectrum， and concordance between mNGS and conventional culture were compared. Factors including infection site， underlying diseases， and immune status associated with mNGS positivity were evaluated. The impact of adjusting antimicrobial therapy based on mNGS results on patient prognosis was also analyzed. ResultsThe positive detection rate of mNGS was significantly higher than that of conventional culture （85.11% vs. 47.14%， P ＜ 0.001）. mNGS enabled rapid identification of rare pathogens and mixed infections， with higher positivity observed in immunosuppressed patients and those with hematological disorders （P ＜ 0.05）. Adjustment of antimicrobial therapy based on mNGS results showed no significant difference in short-term clinical response； however， 28-day mortality differed significantly among groups （adjusted group 39.1%， non-adjusted group 76.3%， supportive group 31.4%； χ²= 22.44， P ＜ 0.001）. Multivariate logistic regression analysis identified age and mechanical ventilation as independent factors associated with pathogen positivity. Age， coronary heart disease， SOFA score， bilirubin level， and the use of mechanical ventilation and vasoactive drugs were independent risk factors for 28-day mortality， whereas platelet count and renal function showed protective associations. Patients whose antimicrobial therapy was adjusted based on mNGS results demonstrated a trend toward clinical improvement， shorter antibiotic duration， faster fever resolution， and lower 28-day case fatality rate. ConclusionmNGS demonstrates high sensitivity and broad pathogen coverage for etiological diagnosis in EICU sepsis patients and provides critical support for precision antimicrobial therapy. Patient age， underlying diseases， disease severity， and organ function are key determinants of pathogen detection and short-term prognosis， offering valuable guidance for risk stratification and optimization of therapeutic strategies.
