Hyperthyroidism （HT） is frequently complicated by atrial fibrillation （AF） in clinical practice. Based on traditional Chinese medicine （TCM） zang-xiang （藏象） theory and clinical experience， both HT and AF are closely associated with dysfunction of the liver. The pathogenesis is initiated by the liver failing to govern the free flow of qi， and liver constraint and qi stagnation， with the key turning points being liver constraint transforming into fire and the internal stirring of liver wind， ultimately leading to liver blood depletion and insufficient nourishment of the heart spirit. Thus， it is proposed to treat the disease from the liver， with stage-specific therapeutic approaches according to the evolution of the disease. In the early stage， the treatment should focus on soothing the liver and relieving constraint to reduce goiter and calm the heart， while in the progressive stage， the method of clearing liver and draining fire is suggested to subdue yang and stabilize palpitations. In the acute stage， the strategy is calming the liver and nourishing yin to subdue yang and extinguish wind. In the later stage， it is suggested to soften the liver and benefit qi， so as to nourish yin and restore pulse. These methods are sequentially applied to synergistically reduce goiter and stabilize palpitations， providing a therapeutic approach for HT complicated by AF.

Objective:To investigate the effects of Xiaomudan Granules on PERK/eIF2α/ATF4 pathway and lipid metabolism in NAFLD mice.Methods:Totally 60 mice were divided into a normal group of 10 mice and a high-fat diet group of 50 mice. The high-fat diet group was given a high-fat diet to establish a NAFLD mouse model. The high-fat feed group was divided into model group, metformin group, and Xiaomudan Granules low-, medium-, and high-dosage groups according to the random number table method. Xiaomudan Granules low-, medium-, and high-dosage groups were orally administered with concentrated Xiaomudan Granules at dosages of 11.7, 23.4, and 46.8 g/kg, respectively. The metformin group was orally administered with metformin solution at a dose of 0.2 g/kg, while the normal group and model group were orally administered with distilled water of equal volume once a day for 8 consecutive weeks. The liver oil red O staining of mice was observed in each group. The protein expressions of p-PERK, p-eIF2α, ATF4, C/EBP homologous protein (CHOP), CCAAT enhancer binding protein alpha (C/EBPα), C/EBPβ, and steroid regulatory element binding protein 2 (SREBP2) were detected by Western blot. Fluorescence quantitative PCR was used to detect the mRNA expressions of ATF4, CHOP, C/EBPα, C/EBPβ, and SREBP2.Results:The liver tissue structure and steatosis of mice were improved in Xiaomudan Granules groups. Compared with the model group, the expressions of p-PERK/PERK, ATF4, C/EBPα, C/EBPβ, and SREBP2 proteins decreased in Xiaomudan Granules groups and the metformin group ( P<0.01 or P<0.05). The expressions of p-eIF2α/eIF2α and CHOP proteins decreased in the Xiaomudan Granules medium- and high-dosage groups and the metformin group ( P<0.01); compared with the model group, the levels of ATF4, CHOP, C/EBPα, and C/EBPβ mRNA in Xiaomudan Granules groups and the metformin group decreased ( P<0.01), while the levels of SREBP2 mRNA in the Xiaomudan Granules medium- and high-dosage groups and the metformin group decreased ( P<0.01). Conclusion:Xiaomudan Granules may improve liver lipid metabolism and reduce liver fat deposition in NAFLD mice by regulating the PERK/eIF2α/ATF4 pathway.

ObjectiveTo investigate the current status and related factors of maternal influenza vaccination willingness among pregnant and postpartum women in Shanghai and Liaoning Province, China, and to explore the facilitators and barriers affecting vaccination uptake, so as to provide references for future practices in promoting maternal influenza immunization in China. MethodsA convergent mixed-methods research was conducted. From January to March 2024, a questionnaire survey was conducted among women attending prenatal and postnatal care at 7 medical institutions in Shanghai and Dalian, Liaoning Province, which aimed to assess pregnant women’s knowledge about influenza vaccine and their willingness to vaccination during pregnancy, as well as to identify the related factors. In addition, purposive sampling method was used to conduct in-depth interviews with pregnant women and perinatal healthcare service providers to explore their perspectives on influenza vaccination during pregnancy, including the reasons for their willingness or unwillingness to receive ( or recommend) the vaccine, and the relevant facilitators and barriers to vaccination. ResultsA total of 366 pregnant and postpartum women participated in the questionnaire survey, and 9.56% (35/366) of them were willing to receive the influenza vaccine during pregnancy. The results of multivariate logistic stepwise regression analyses showed that primipara (aOR=0.158, 95%CI: 0.037‒0.671, P=0.012), family members’ support for influenza vaccination during pregnancy (aOR=0.015, 95%CI: 0.003‒0.082, P<0.001) were associated with higher willingness to receive influenza vaccine during pregnancy. Absence of influenza infection during pregnancy (aOR=5.383, 95%CI: 1.801‒16.092, P<0.001), and lack of knowledge regarding influenza vaccination during pregnancy (aOR=11.294, 95%CI: 3.593‒35.496, P<0.01) were associated with lower willingness to receive influenza vaccine during pregnancy. Qualitative findings indicated that the facilitators to vaccination willingness among pregnant and postpartum women included the recommendation of healthcare service providers, adequate knowledge of influenza vaccine information and family members’ support for vaccination. Conversely, the barriers to vaccination willingness included low recommendation from the healthcare service providers, lack of knowledge about the safety of influenza vaccine during pregnancy and inadequate attention to influenza and influenza vaccine. ConclusionThe willingness to receive influenza vaccination among pregnant and postpartum women in Shanghai and Liaoning Province is relatively low. It is recommended that China should promptly improve the evidence-based system for the safety and efficacy of influenza vaccines for pregnant and postpartum women, along with an establishment of the mechanism for addressing adverse reactions. Furthermore, it is essential to enhance educational outreach to pregnant and postpartum women, their families, and healthcare service providers, thereby increasing the accessibility of information regarding influenza vaccination, which are expected to enhance the willingness of pregnant and postpartum women to receive the vaccine.

Objective:To discuss the characteristics of age,antral follicle count(AFC),anti-Müllerian hormone(AMH),sex hormones,and glycolipid metabolism in the infertile patients with different phenotypes of polycystic ovarian syndrome(PCOS),and to improve the outcomes of assisted reproductive technology(ART).Methods:A total of 11 660 infertile female patients treated in our hospital were selected as the research subjects,including 3 110 PCOS patients and 8 550 non-PCOS patients.According to the Rotterdam criteria and inclusion/exclusion criteria,the subjects were divided into PCOS group(2 261 PCOS patients)and control group(1 871 non-PCOS patients).The PCOS group was further divided into four phenotypes:type A(345 cases,oligo-ovulation or anovulation(OA)+hyperandrogenemia or clinical hyperandrogenism(HA)+polycystic ovary morphology(PCO)),type B(204 cases,OA+HA),type C(102 cases,HA+PCO),and type D(1 610 cases,OA+PCO).Chemiluminescent immunoassay was used to detect the serum AMH levels of the subjects in various groups;glucose oxidase method and biochemical method were used to detect the serum levels of triglycerides(TG),total cholesterol(TCHO),fasting blood glucose(FBG),and fasting insulin(FINS)of the subjects in various groups;chemiluminescence method was used to detect the serum basal sex hormone levels of the subjects in various groups;transvaginal ultrasound was used to detect the AFC of the subjects in various groups.Results:Compared with control group,the age and serum basal follicle-stimulating hormone(bFSH)levels of the subjects in different PCOS phenotype groups were significantly decreased(P<0.01),while AFC and serum levels of AMH,total testosterone(TESTO),and basal luteinizing hormone(bLH)of the subjects were significantly increased(P<0.01).Compared with type A PCOS group,the AFC and serum levels of AMH and bLH of the subjects in type B,C,and D PCOS groups were significantly decreased(P<0.01).Compared with control group,the serum levels of TG,TCHO,FBG,and FINS,as well as homeostasis model assessment of insulin resistance(HOMA-IR)of the subjects in type A and D PCOS groups were significantly increased(P<0.01);the serum levels of FBG and FINS,as well as HOMA-IR of the subjects in type B PCOS group were significantly increased(P<0.01);the serum TG level of the subjects in type C PCOS group was significantly increased(P<0.01).Compared with type A PCOS group,the serum levels of TG and FINS,as well as HOMA-IR of the subjects in type B,C,and D PCOS groups were significantly decreased(P<0.01).Conclusion:The patients with different PCOS phenotypes exhibit distinct basal sex hormone levels and glycolipid metabolism characteristics.Phenotypic classification of PCOS infertile patients helps predict disease severity,and personalized pretreatment should be performed for different PCOS phenotypes before ART.

Objective To investigate the efficacy of externally applied mirabilite combined with infrared irradiation in promoting wound healing following biliary tract surgery.Methods Patients who underwent open surgery for biliary tract disease in our department between January 2022 and April 2025 were randomly assigned to one of three groups:(1)Combination group(n=60),which received postoperative wound treatment with mirabilite application combined with infrared irradiation;(2)Mirabilite group(n=60),treated with mirabilite application alone;and(3)Infrared group(n=60),treated with infrared irradiation alone.The primary outcomes included wound healing grade on postoperative day 7,pain intensity measured on days 3,5,and 7,and wound healing status up to discharge.For cases with suboptimal healing,the duration required for complete healing following intervention was documented.Secondary outcomes encompassed length of postoperative hospital stay and Vancouver Scar Scale(VSS)scores—assessing scar pigmentation,thickness,vascularity,and pliability—evaluated at 3 months postoperatively.Results The combination group exhibited significantly lower rates of poor wound healing,shorter postoperative hospital stays,improved VSS scores—particularly in terms of scar thickness and pliability—and reduced pain levels on the 3rd and 5th postoperative days compared to the other two groups(P<0.05).Conclusions The combined use of mirabilite and infrared irradiation for surgical incisions following biliary tract surgery represents an effective,economical,and readily accessible adjuvant therapy.It significantly reduces the incidence of impaired wound healing and effectively alleviates early postoperative pain,thereby demonstrating strong potential for clinical promotion.

Objective:To compare the efficacy, safety, and cost-effectiveness of the trastuzumab originator (HST) versus its biosimilar (HLX02) combined with pertuzumab and chemotherapy as neoadjuvant treatment in patients with HER-2-positive breast cancer.Methods:This retrospective cohort study included 175 patients with HER-2-positive breast cancer who received neoadjuvant therapy followed by curative surgery at the Cancer Hospital Chinese Academy of Medical Sciences between October 2020 and January 2024. Patients were divided into two groups based on the trastuzumab formulation used: the HST group ( n=89) and the HLX02 group ( n=86).The efficacy, safety, and trastuzumab-related treatment costs were compared between the two groups. Moreover, using Logistic regression model to identify the factors influencing total pathological complete response (tpCR) rates. Results:There were statistically significant differences in clinical T stage and surgical approach between the HST and HLX02 groups ( P＜0.05). Other clinicopathological characteristics, such as age and histological grade, showed no statistically significant differences ( P＞0.05), with most baseline characteristics remaining balanced between the two groups. There were no significant differences in tpCR rates ( P=0.957) or Miller-Payne (MP) grading rates ( P=0.991) between the HST and HLX02 groups. The tpCR rates for the two groups were 55.1% (49/89) and 54.7% (47/86), respectively. The rates of achieving grade 5 (G5) in the postoperative MP pathological grading system were 55.1% (49/89) and 55.8% (48/86), respectively, with no statistically significant difference ( P=0.991). Univariate and multivariate Logistic regression analyses showed that hormone receptor status is an independent risk factor affecting tpCR ( OR=0.31, 95% CI; 0.16-0.61, P＜0.001). The incidence of adverse event during neoadjuvant therapy was similar between the groups, with no occurrences of trastuzumab-related cardiac toxicity. The HLX02 regimen showed a lower cost-effectiveness ratio (586.48 vs. 604.96) and reduced trastuzumab treatment costs during neoadjuvant therapy compared to HST [tpCR:(31 208.37±2 191.00) CNY vs. (33 224.49±2 741.00) CNY; non-tpCR: 33 030.05±5 787.00) CNY vs. (33 412.50±4 203.00) CNY, P＜0.05]. Conclusions:In the neoadjuvant treatment of early-stage HER-2-positive breast cancer, HLX02 combined with pertuzumab and chemotherapy demonstrates similar efficacy and safety to the trastuzumab originator, while offering a significant cost advantage.

Objective:To systematically summarize, describe, and evaluate the evidence related to convex baseplates use in adult ostomy patients through an evidence map, in order to identify research gaps and future directions.Methods:A systematic search was conducted in Chinese and English databases, including China National Knowledge Infrastructure, Wanfang Data, VIP, and PubMed, and others, from database inception to September 2024. Randomized controlled trials and quasi-experimental studies on convex baseplates use in adult ostomy patients were included. Literature quality was assessed using the Cochrane Handbook 5.1.0 bias risk assessment tool and the critical appraisal tool for quasi-experimental studies from the Joanna Briggs Institute Centre for Evidence-Based Healthcare. Based on the PICO principle [participant (P) , intervention (I) , comparison (C) , outcome (O) ] , an evidence mapping coding system was extracted and developed by integrating relevant guidelines and consensus. Data extraction and coding were performed using EPPI-Reviewer software, and key evidence characteristics and literature quality were presented using bubble charts.Results:A total of eight randomized controlled trials and six quasi-experimental studies were included. Most of the 14 studies had a high risk of bias. The target populations for interventions were divided into two categories: prevention and treatment. The main complications involved stoma skin-mucosal separation, stoma peristomal dermatitis, and stoma height issues. The main outcome measures included baseplate seal integrity, wound healing, complication rates, clinical symptoms, adverse events, patient acceptance, and quality of life.Conclusions:Most of the studies on convex baseplates has focused on enterostomy patients. The majority of studies have a high risk of bias, and the number of studies is limited. Further clarification is needed on the selection criteria for convex baseplates with different characteristics, and the clinical application effects of convex baseplates urgently need further evaluation.

Objective:To investigate the current status of convex baseplate selection and use among clinical nurses.Methods:A convenience sampling method was employed to survey 1 873 nurses from 180 hospitals across China between November and December 2024 using a general information questionnaire and a self-designed questionnaire on convex baseplate selection and use. A total of 1 873 questionnaires were distributed, and 1 860 valid responses were collected, yielding a response rate of 99.31% (1 860/1 873) .Results:Among the 1 860 nurses, 88.98% (1 655/1 860) had access to convex baseplates in clinical practice. However, only 8.82% (146/1 655) used them immediately postoperatively, and only 4.53% (75/1 655) chose convex baseplates without considering any product features. The five common clinical indications for convex baseplate use included stoma retraction (96.62%, 1 599/1 655) , peristomal skin folds or depressions (96.56%, 1 598/1 655) , flush stomas (80.12%, 1 326/1 655) , leakage (70.03%, 1 159/1 655) , and abdominal laxity (66.89%, 1 107/1 655) . Common contraindications for use included peristomal varicose veins (77.46%, 1 282/1 655) , peristoma pressure injuries (75.35%, 1 247/1 655) , stoma prolapse (74.50%, 1 233/1 655) , parastomal hernia (72.87%, 1 206/1 655) , and pyoderma gangrenosum (67.01%, 1 109/1 655) . Key assessment areas when selecting convex baseplates included the stoma itself (97.28%, 1 610/1 655) , peristomal skin (96.50%, 1 597/1 655) , abdominal wall contour (95.41%, 1 579/1 655) , excretion patterns (87.37%, 1 446/1 655) , and previous convex baseplate use (82.36%, 1 363/1 655) . Measures commonly used by nurses to enhance adhesion included the use of stoma belts (95.29%, 1 577/1 655) , barrier rings or paste (94.80%, 1 569/1 655) , smoothing peristomal skin folds (90.57%, 1 499/1 655) , advising patients to limit bending (82.96%, 1 373/1 655) , and abdominal binders (57.28%, 948/1 655) .Conclusions:The clinical application of convex baseplates requires further promotion. Nursing administrators should strengthen training on the selection, characteristics, and indications of convex baseplates, with particular emphasis on the understanding of the five key product features.

[Objective]To investigate the presence of SARS-CoV-2 RNA in semen after COVID-19 infection in vaccinated individuals and to evaluate the impact of different recovery stages on sperm quality.[Methods]From January to March 2023,vaccinated male patients with recent SARS-CoV-2 infections confirmed by throat swabs were recruited from the Reproductive Medicine Center at the First Affiliated Hospital of Anhui Medical University.Semen samples were analyzed with RT-qPCR to detect SARS-CoV-2 RNA.A retrospective analysis assessed sperm quality across recovery stages,comparing patients within 30 days of recovery to those with 30 days or more.Semen parameters evaluated included volume,total sperm count,forward motility percentage,abnormal morphology rate,and sperm DNA fragmentation index.In addition,a longitudinal self-comparison was performed to examine changes in semen quality before and after recovery(＜30 days and≥30 days).[Results]SARS-CoV-2 RNA was undetectable in the semen of all 205 patients.Neither cross-sectional comparisons nor longitudinal analyses showed significant differences in semen volume,sperm concentration,total sperm count,sperm morphology rate,sperm DNA fragmentation index,or high DNA stainability between recovery stages or compared to pre-infection values(P＞0.05).However,forward motility percentage markedly decreased during recovery,with statistical significant between groups(P＜0.05).[Conclusions]In vaccinated individuals who contracted COVID-19,SARS-CoV-2 was not transmitted through semen.Although the incidence of asthenozoospermia may increase within 30 days post-infection,this effect appears reversible in the short time.

OBJECTIVE To observe the effects of silicone oil removal detergent and multi-enzyme detergent on re-moving the residual silicone oil from digestive endoscopes so as to provide bases for clinical cleaning of digestive endoscopes.METHODS Totally 60 colonoscopes that were used in the endoscopy center of Shenzhen Hospital of Southern Medical University in Jul.2024 were chosen as the research subjects and were randomly divided in to the experimental group with 30 colonoscopes(the silicone-removing multi-enzyme detergent group)and the control group with 30 colonoscopes(the multi-enzyme detergent group),the two groups were respectively treated with sil-icone-removing multi-enzyme detergent and multi-enzyme detergent during the cleaning process.The average bac-terial colony counts of rinsed endoscopes,residual water droplet counts of the cleaned endoscopes and absorbance values of residual methyl silicone oil in the biopsy forceps channels of the endoscopes were observed and compared between the two groups so as to evaluate the effect on removing silicone oil.RESULTS The median average bacteri-al colony counts were 3.05(1.62,4.68)× 103 CFU/piece in the experimental group,36.70(34.66,38.10)× 103 CFU/piece in the control group(Z=-6.654,P＜0.001).The median counts of residual water droplets on the en-doscopes were 7.00(5.00,16.50)in the experimental group,31.50(12.00,43.00)in the control group(Z=-3.940,P＜0.001).The median absorbance value of residual methyl silicone oil in the biopsy forceps chan-nels of the endoscopes was 6.85(5.58,7.85)× 10-3 in the experimental group,36.50(35.50,43.65)× 10-3 in the control group(Z=-6.655,P＜0.001).CONCLUSION The silicone-removing multi-enzyme detergent shows more remarkable effect on removing the residual silicone oil on the endoscopes than the multi-enzyme detergent,it improves the cleaning effect of the endoscopes and is worthy to be verified and promoted in the hospital.
