Chronic eczema has a high prevalence in China， significantly impacting patients’ quality of life. Leveraging the unique advantages of pattern identification/syndrome differentiation and treatment， along with a holistic approach， traditional Chinese medicine （TCM）， which integrates internal and external therapies， has been widely applied in the management of chronic eczema. It has demonstrated significant efficacy and distinctive strengths in alleviating symptoms， reducing recurrence rates， maintaining disease stability， and enhancing patients’ quality of life. Oral administration of TCM（e.g. modified Longdan xiegan decoction） can improve patients’ clinical symptoms through systemic regulation. External use of TCM can directly act on the skin lesion with the help of steaming and washing， hydropathic compress， ointment and other forms. At the same time， it can effectively relieve the clinical symptoms of chronic eczema by combining with non-drug therapies such as acupuncture， moxibustion， acupoint catgut embedding， blood-letting puncture and cupping. In addition， characteristic therapies such as oral administration of TCM combined with external treatment， a combination of various external treatments and a combination of Chinese and Western medicine have also demonstrated certain advantages in regulating immune function， alleviating skin lesions， and relieving itching symptoms. These therapies cooperate with each other， creating a synergistic effect that treats both the symptoms and the root cause simultaneously. It is suggested that more high-quality， large-scale clinical research should be conducted in the future to systematically confirm the therapeutic advantages of TCM and further explore the specific molecular mechanism of action.

Chronic mucocutaneous candidiasis (CMC) is an infectious phenotype characterized by recurrent or persistent infections caused by Candida species that affect the skin, nails, oral, and genital mucosae for a duration exceeding six months. Current research suggests that CMC is an immunodeficiency disease with a complex pathogenesis. Patients with CMC have various defects in nonspecific and/or specific immunity against Candida infection, resulting in the inability of patients to defend themselves against Candida infection. CMC can be stratified into primary CMC and secondary CMC based on etiology. Primary CMC is often associated with genetic mutations leading to immunodeficiencies in T helper cell 17 and interleukin-17, whereas secondary CMC is frequently linked to factors such as human immunodeficiency virus infection, diabetes mellitus, and immunosuppressive therapy. Primary CMC typically manifests as Candida infections, with distinct genetic mutations often correlating to varied concomitant symptoms. Secondary CMC may present with not only superficial mucosal Candida infections and manifestations of the underlying primary disease but also with invasive fungal infections. Diagnosing CMC requires an integration of medical history and clinical presentation, supplemented by the outcomes of auxiliary diagnostic procedures, including microscopic examination of fungal smear, fungal culture, immunological testing, and genetic sequencing and analysis. Furthermore, confirming primary CMC requires exclusion of the aforementioned secondary factors. At present, antifungal drugs such as triazoles, echinocandins, and polyenes are the main treatment for CMC. Moreover, immunotherapy with biologics such as Janus kinase (JAK) inhibitors provides more options for the clinical treatment of patients with CMC. Gene therapy also has potential clinical application value. In this review, we discuss the etiologies, pathogenesis, clinical manifestations, diagnosis, and treatments of CMC, aiming to provide a reference for the clinical diagnosis and treatment of CMC.

Based on the "regulating the pivot and unblocking the stomach" theory， this article proposes that the core pathogenesis of bile reflux gastritis （BRG） is disharmony of the three pivots and imbalance between the gallbladder and the stomach. Specifically， the pivot of zang-fu （脏腑） organs （spleen and stomach） exhibits abnormal ascending and descending functions， while the pivot of opening and closing （shaoyang） shows impaired flow， and the pivot of mind （heart and brain） has disordered regulation. These three pivots interact， ultimately leading to bile reflux attacking the stomach， injuring the gastric mucosa， and causing symptoms such as epigastric distension， pain， acid regurgitation， and heartburn. Clinically， the treatment principle is unblocking and regulating the three pivots， harmonizing the gallbladder and descending stomach qi， which closely follows the different pathomechanisms of three-pivot dysregulation， applying treatment according to syndrome differentiation. The regulation of the pivot of zang-fu organs focuses on fortifying the spleen and harmonzing stomach， raising the clear and directing the turbid downward. The regulation of the opening-and-closing pivot emphasizes harmonizing shaoyang， promoting gallbladder function and bowel movement. The regulation of the mind pivot centers on calming the heart and the mind， and harmonizing the stomach to ensure smooth qi flow. "Unblocking and regulating three pivots" method aims to restore the physiological functions of the gallbladder and stomach， providing a conceptual framework for the clinical management of BRG.

ObjectiveTo construct and evaluate a mouse model that simulates the pathological progression of immune checkpoint inhibitor-associated pneumonitis (CIP), in order to address the critical issue of the lack of standardized animal models in this research field. MethodsThirty-five SPF-grade 6-week-old male C57BL/6J mice were randomly assigned to a control group (n=5), a bleomycin (BLM) group (n=15), and a BLM+programmed death-1 (PD-1) monoclonal antibody (BLM+PD-1) group (n=15). Corresponding drugs were administered via intraperitoneal injection for intervention. The general condition, body weight changes, survival rate, and pulmonary histopathological alterations were systematically monitored. ResultsCompared with the BLM group, the BLM+PD-1 group exhibited significantly more severe pulmonary fibrosis, characterized by progressive body weight loss and more severe deterioration of general conditions. Histopathological examination showed that pulmonary inflammation was alleviated 4 weeks post-modeling in the BLM group. In contrast, pulmonary lesions continued to worsen in the BLM+PD-1 group, with no evidence of resolution of inflammation 28 days post-modeling. Quantitative immunohistochemical analysis revealed that the positive expression rate of interleukin-17A (IL-17A) in lung tissues reached 34.28% in the BLM+PD-1 group 14 days post-modeling, which was markedly higher than that in the BLM group (24.02%, P < 0.000 1). The positive expression rate of α-smooth muscle actin (α-SMA) was 12.40% in the BLM+PD-1 group 14 days post-modeling, nearly twice the level in the BLM group (5.87%). 28 days post-modeling, the positive expression rate of α-SMA remained at 7.72% in the BLM+PD-1 group, while it declined to 3.38% in the BLM group. ConclusionThe addition of a PD-1 inhibitor to bleomycin treatment accelerates the progression of pulmonary interstitial fibrosis and effectively recapitulates the pathological process of lung injury and fibrosis driven by aberrant immune activation during clinical immunotherapy. Accordingly, this study successfully establishes a dynamic CIP animal model recapitulating the progression from early inflammatory response to pulmonary fibrosis. This model addresses the critical shortage of animal models for this condition and offers an experimental platform for further mechanistic studies and the development of therapeutic strategies.

ObjectiveTo investigate the differential expression of LEFTY1 in peritoneal dialysis （PD）-associated peritoneal fibrosis （PF） and its clinical value. MethodsLevels of LEFTY1， transforming growth factor-β （TGF-β）， and fibronectin （FN） in peritoneal dialysis effluent were measured in 72 PD patients， and clinical data were collected. Differences in these indicators were compared among groups with different dialysis durations， and the correlation between LEFTY1 and clinical parameters was analyzed to evaluate its predictive value for ultrafiltration insufficiency. ResultsLEFTY1 levels decreased progressively with longer dialysis duration： short-term group ［（2 262.49±270.47） ng/mL］ > mid-term group ［（1 853.52±226.06） ng/mL］ > long-term group ［（1 767.24±264.57） ng/mL］， with significant differences among groups （P<0.001）. TGF-β and FN levels increased with prolonged dialysis duration （P<0.05）. Correlation analysis revealed that LEFTY1 was significantly negatively correlated with FN （r=-0.327， P=0.004）， dialysis duration （r=-0.496，P<0.001）， peritoneal Kt/V （r=-0.333， P=0.004）， peritoneal creatinine clearance （r=-0.239， P=0.043）， and serum calcium （r=-0.410， P<0.001）， while positively correlated with total creatinine clearance （r=0.283， P=0.016）. The area under the ROC curve for LEFTY1 combined with peritoneal Kt/V and peritoneal Ccr in predicting ultrafiltration insufficiency was 0.739. Multivariate regression analysis identified dialysis duration as an independent influencing factor for LEFTY1 expression （P=0.001）. ConclusionThe expression of LEFTY1 in the peritoneal dialysis effluent of PD patients decreases with prolonged dialysis duration and is negatively correlated with pro-fibrotic indicators， suggesting that it may play a potential anti-fibrotic role in the progression of PF. The combined detection of LEFTY1 and solute removal indicators holds value for the early identification of ultrafiltration dysfunction.

Objective To investigate the prevalence and related factors of sarcopenia among non–bedridden older adults in the community of Baoshan District using the China mini sarcopenia risk assessment 7 (C-MSRA-7) combined with Ishii scoring system. Methods The older individuals consulting at 20 community health stations in Baoshan District between April 2025 and June 2025 were enrolled. Data were collected using a general information questionnaire, a dietary and lifestyle habits survey, the C-MSRA-7, and the mini nutritional assessment-short form (MNA-SF). Handgrip strength and anthropometric measurements were also obtained. Individuals with both Ishii score and C-MSRA-7 results positive were classified into the sarcopenia risk group, while the remaining participants were assigned to the non–sarcopenia risk group. Differences in lifestyle habits, dietary patterns, and nutritional status between the two groups were compared. Results A total of 2 611 valid questionnaires were retrieved. Univariate analysis showed statistically significant differences in alcohol consumption, physical activity frequency, body mass index (BMI), nutritional status, activities of daily living, and regularity of three meals in sarcopenia risk group (n＝486) and non–sarcopenia risk group (n＝2 125, P<0.05). Logistic regression analysis showed that advanced age (75–84 years: OR＝2.55, 95%CI 2.03–3.21; ≥85 years: OR＝3.98, 95%CI 2.24–7.07), underweight status (OR＝2.19, 95%CI 1.50–3.19), weight loss＞2 kg (OR＝4.52, 95%CI 2.68–7.64) past 3 months, lack of regular physical activity (OR＝1.77, 95%CI 1.24–2.52) , and alcohol consumption (OR＝1.48, 95%CI 1.07–2.05) were independent risk factors for sarcopenia (P<0.05). Behaviors related to healthy diet, including daily milk consumption (OR＝0.40, 95%CI 0.30–0.52), regular three meals (OR＝0.56, 95%CI 0.41–0.78), and high-quality protein intake (OR＝0.70, 95%CI 0.52–0.94), were protective factors (P<0.05). Conclusions Sarcopenia among community–dwelling, non–bedridden older adults is closely associated with physical activity levels, dietary habits, and nutritional status. Early identification of individuals at risk, enhanced nutritional education, and timely implementation of nutritional interventions and exercise programs are recommended for this population.

ObjectiveTo explore the predictive value of serum cystatin C （CysC） and trabecular bone score （TBS） for postoperative fracture recurrence in elderly patients with osteoporotic vertebral fractures. MethodsA total of 100 elderly patients with osteoporotic vertebral fractures who were treated surgically at Fuling Hospital Affiliated to Chongqing University from June 2022 to June 2023 were followed up for 2 years. They were divided into the poor group （31 cases） and the good group （69 cases） based on the postoperative fracture recurrence. Pearson analysis was used to analyze the correlation between serum CysC and TBS， Cox analysis was used to analyze the influencing factors of postoperative fracture recurrence in elderly patients with osteoporotic vertebral fractures， and ROC analysis was used to analyze the predictive value of serum CysC and TBS for postoperative fracture recurrence in patients. ResultsThe proportion of bone cement penetration and serum CysC in the poor group were significantly higher than those in the good group （χ² = 4.977， P = 0.026； t = 4.749， P = 0.000）， while the proportion of postoperative anti-osteoporosis treatment， bone mineral density T value， and TBS were significantly lower than those in the good group （χ² = 4.229， P = 0.040； t = 2.065， P = 0.042； t = 5.163， P = 0.000）. Serum CysC was negatively correlated with TBS （r = -0.318， P = 0.001）. Elevated serum CysC was a risk factor for postoperative fracture recurrence in elderly patients with osteoporotic vertebral fractures （P < 0.05）， while elevated TBS was a protective factor （P < 0.05）. The AUC of serum CysC for predicting postoperative fracture recurrence in patients was 0.786 （95%CI = 0.679-0.894）， with a sensitivity of 77.42% and a specificity of 71.01%. The AUC of TBS for predicting postoperative fracture recurrence in patients was 0.795 （95%CI = 0.698-0.892）， with a sensitivity of 74.19% and a specificity of 79.71%. The AUC of the combination of serum CysC and TBS for predicting postoperative fracture recurrence in patients was 0.858 （95%CI = 0.773-0.943）， with a sensitivity of 74.19% and a specificity of 82.61%. The combination of the two had a higher predictive value for postoperative fracture recurrence in patients. ConclusionsElderly patients with osteoporotic vertebral fractures who experience postoperative fracture recurrence have elevated serum CysC and decreased TBS. The combination of serum CysC and TBS has a certain predictive value for postoperative fracture recurrence in elderly patients with osteoporotic vertebral fractures.

Objective To investigate the clinical efficacy of Yiqi Huoxue Prescription(derived from Shengyu Decoction)in the treatment of mild cervical spondylotic myelopathy(CSM)with qi deficiency and blood stasis type.Methods A total of 128 patients with mild CSM of qi deficiency and blood stasis type who admitted to Guangdong Provincial Hospital of Chinese Medicine from January 2022 to January 2024 were randomly divided into the control group and the trial group according to the random number table method,with 64 cases in each group.The control group was treated with oral administration of Mecobalamin Tablets,and the trial group was treated with Yiqi Huoxue Prescription orally on the basis of treatment for the control group.The two groups were all treated for four weeks,and then were followed up for three months after the completion of treatment.The CSM scores of the Japanese Orthopedic Association(JOA)and the traditional Chinese medicine(TCM)syndrome scores in the two groups were observed before treatment,after two weeks of treatment,after four weeks of treatment,and three months after the completion of treatment.And then the clinical efficacy,progression of CSM and the incidence of adverse reactions of the two groups were evaluated.Results(1)During the trial,two cases in the control group and three cases in the trial group fell off,and eventually a total of 123 cases were included,62 cases in the control group and 61 cases in the trial group.(2)Three months after the completion of treatment,the total effective rate of the trial group was 93.44%(57/61)and that of the control group was 82.26%(51/62),and the intergroup comparison(tested by chi-square test)showed that the efficacy of the trial group was significantly superior to that of the control group,the difference being statistically significant(P<0.05).(3)After two and four weeks of treatment as well as three months after the completion of treatment,JOA scores in the two groups were increased compared with those before treatment(P<0.05),and JOA scores of the trial group at various time points mentioned above were higher than those of the control group,the difference being statistically significant(P<0.05).(4)After two and four weeks of treatment as well as three months after the completion of treatment,TCM syndrome scores in the two groups were decreased compared with those before treatment(P<0.05),and TCM syndrome scores of the trial group at various time points mentioned above were lower than those of the control group,the difference being statistically significant(P<0.05).(5)During the follow-up period,there was none case of significant aggravation or progression to moderate-severe illness in the two groups,and there were no adverse events such as allergies and gastrointestinal reactions.Conclusion Yiqi Huoxue Prescription exerts certain efficacy in treating patients with mild CSM of the qi deficiency and blood stasis type,and the treatment method is effective on improving the spinal cord function and symptoms of qi deficiency and blood stasis type,and slowing down the progression of disease in the patients,with high safety.

Chronic eczema is clinically characterized by pruritus and skin lesions such as macules,exudation,desquamation,and lichenification.Traditional Chinese medicine(TCM)typically attributes its pathogenesis to wind,dampness,and heat pathogens,and TCM treatment for chronic eczema focused on dispelling wind,eliminating dampness,and clearing heat.However,there were fewer reports about the treatment of accompanying emotional changes and sleep disturbances in chronic eczema patients.This paper integrated the physique-qi-spirit trinity life view with zang-fu organ differentiation,and proposed that the disorder of spleen transportation and transformation contributed to the pathological foundation of chronic eczema,while the dysfunction of heart and liver was the factor that significantly influenced disease progression after analyzing the clinical features of chronic eczema.For the treatment of chronic eczema,the establishment of strategies should consider clinical characteristics,duration of disease,and skin lesion patterns.The combination of physique-qi-spirit regulation with heart-liver-spleen treatment approaches aims to alleviate clinical symptoms,improve quality of life,and enhance therapeutic efficacy for chronic eczema patients.

Objective Focusing on gynecological surgery,we constructed a prediction model for surgical duration by extracting features from unstructured surgical planning texts and integrating multimodal data via artificial intelligence technology.Methods The clinical data of 34 614 patients who underwent gynecologic surgeries at West China Second University Hospital,Sichuan University between January 2022 and October 2024 were collected.An embedding-transformer model was constructed to convert surgical planning texts into a one-dimensional numerical feature,referred to as the step feature.The predictive value of the step feature was assessed by comparing the performance improvements of linear regression,random forest,eXtreme Gradient Boosting(XGBoost),support vector regression,K-nearest neighbor regression,and artificial neural network algorithms in two scenarios—with and without the step feature as an input.The out-of-sample prediction accuracy of the models was assessed using mean absolute error(MAE),root mean squared error(RMSE),and R-squared(R2).Furthermore,the model interpretability was examined using SHapley Additive exPlanations(SHAP)values.Results SHAP results showed that the step feature had the highest predictive contribution.Temporal factors in surgical scheduling also influenced gynecological surgery duration.The XGBoost model demonstrated optimal performance on the test set,significantly improving prediction accuracy with a 40.43%increase in R2,while reducing MAE and RMSE by 21.27%and 20.13%,respectively,compared to the baseline model without the step feature.Conclusion The embedding-transformer model developed in this study effectively extracts features from surgical planning texts and enhances the predictive performance of machine learning models.The XGBoost prediction model can assist hospital administrators in implementing more refined management of gynecological surgeries and improving the utilization efficiency of surgical resources.
