Chronic liver disease is a general term for a variety of liver diseases， and its prevalence rate is increasing year by year. With the progression of the disease， patients may experience a variety of serious complications and even progress to liver failure. In recent years， a number of studies have revealed the association between ectopically colonized oral bacteria and chronic liver disease and explored their potential value in the diagnosis and treatment of chronic liver disease. This article systematically reviews the association of ectopically colonized oral bacteria with metabolic associated fatty liver disease， liver cirrhosis， and liver cancer and analyzes the mechanism for the influence of ectopically colonized oral bacteria on chronic liver disease， so as to provide a reference for the diagnosis and treatment of chronic liver disease using ectopically colonized oral bacteria.

Objective To explore the prognostic factors for patients with descending duodenum gastrointestinal stromal tumors (GIST), analyze the impact of different surgical approaches on prognosis, and develop a predictive model for surgical approach selection. Methods This single-center retrospective cohort study included patients with primary descending duodenum GIST treated in Zhongshan Hospital, Fudan University from January 2010 to January 2015, with follow-up until August 2025. The primary outcomes were incidence of postoperative complications, disease-free survival (DFS) rate, and overall survival (OS) rate. Cox regression and logistic regression were used to identify factors influencing prognosis and surgical approach selection, respectively. A nomogram model for selecting the surgical approach was constructed. Results A total of 78 patients with descending duodenum GIST were included, with age of (56.14±11.76) years. The 1-, 5-, and 10-year OS rates were 100%, 98.7%, and 85.7%, respectively, and the corresponding DFS rates were 100%, 90.9%, and 82.3%. Intraoperative blood loss, postoperative gastroparesis, mucosal ulceration, maximum tumor diameter, and Ki-67-positive cell ratio were independent risk factors for DFS, while maximum tumor diameter and mitotic figure were independent risk factors for OS (P＜0.05). The 10-year DFS rate was higher in the local resection group than in the pancreaticoduodenectomy group (89.45% vs 74.24%; HR＝0.300, P＝0.013), but there was no statistical difference in OS between the two groups. The incidence of postoperative complications in the pancreaticoduodenectomy group was higher than that in the local resection group (P＜0.001). Maximum tumor diameter and distance from tumor to the duodenal papilla were independent factors influencing surgical approach selection. The nomogram model based on these two indices demonstrated good discrimination and accuracy upon internal validation. Conclusions The long-term prognosis of patients with descending duodenal GIST is favorable, and surgical treatment achieves satisfactory outcomes. The nomogram model developed in this study can effectively guide individualized surgical approach selection and provide a reference for clinical decision-making.

ObjectiveTo investigate the epidemiological characteristics and influencing factors of depressive symptoms among middle school (junior, senior, and vocational high school) students in Yunnan Province, China, and to inform evidence-based intervention strategies for adolescent mental health. MethodsA cross-sectional survey was conducted between October and November 2023 using stratified random cluster sampling. Students from eight counties (districts) across four prefectures (cities) in Yunnan Province were included. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Multivariate logistic regression analysis was performed to examine factors associated with depressive symptoms, with stratified analyses conducted by gender, educational stage, and ethnicity. ResultsA total of 4 672 questionnaires were distributed, with 4 670 valid questionnaires retrieved, yielding a valid response rate of 99.96%. The surveyed participants were predominantly female students (50.81%), junior high school students (49.13%), ethnic minorities (52.78%), and urban residents (79.29%). The mean CES-D score for middle school students in Yunnan Province was (15.31±10.83). Female students had a significantly higher mean score (16.63±11.41) than male students (13.95±10.02) (P<0.001). Senior high school students had a significantly higher mean score (16.61±10.61) compared to both junior high school students (14.74±11.45) and vocational high school students (13.10±7.71) (all pairwise comparisons P<0.001). The prevalence of depressive symptoms among middle school students in Yunnan Province was 28.18%. The prevalence was significantly higher in females (34.09%) than in males (22.07%). By school type, the detection rate was highest among senior high school students (33.39%), followed by junior high school students (26.29%) and vocational high school students (17.27%) (P<0.05). Multivariate logistic regression analysis showed that female gender (OR=2.16, 95%CI: 1.86‒2.50), being in junior high school (OR=2.43, 95%CI: 1.84‒3.20) or senior high school (OR=2.27, 95%CI: 1.73‒2.98), not living with parents (OR=1.24, 95%CI: 1.07‒1.44), irregular breakfast consumption (OR=1.52, 95%CI: 1.33‒1.75), lack of moderate-to-vigorous physical activity (MVPA) (OR=1.69, 95%CI: 1.37‒2.09), sleep duration ≤5 h per night (OR=2.52, 95%CI: 2.02‒3.14) or 6‒7 h per night (OR=1.47, 95%CI: 1.25‒1.73), smoking (OR=1.86, 95%CI: 1.56‒2.23), and alcohol consumption (OR=1.81, 95%CI: 1.54‒2.13) were positively associated with depressive symptoms. In contrast, screen time ≤1 h (OR=0.71, 95%CI: 0.59‒0.86) was negatively associated with depressive symptoms. Stratified analyses showed that female students not living with parents (OR=1.29, 95%CI: 1.06‒1.58), senior high school students (OR=1.51, 95%CI: 1.21‒1.88), and Han Chinese students (OR=1.37, 95%CI: 1.11‒1.69) were more likely to experience depressive symptoms. Han Chinese students who smoked were also more likely to have depressive symptoms (OR=1.72, 95%CI: 1.34‒2.21). In contrast, male students with screen time ≤1 h (OR=0.71, 95%CI: 0.53‒0.95) and ethnic minority students (OR=0.74, 95%CI: 0.58‒0.95) were less likely to experience depressive symptoms. Regardless of gender, irregular breakfast consumption, lack of MVPA, sleep duration less than 8 h per night, smoking, and alcohol consumption were all positively associated with depressive symptoms (P<0.05). Among both junior and senior high school students, irregular breakfast consumption, lack of MVPA, smoking, and alcohol consumption were positively associated with depressive symptoms (all P<0.05), while screen time ≤1 h was negatively associated with depressive symptoms (all P<0.05). For junior high school students, engaging in 1‒2 days of MVPA per week, screen time more than 2 h per day, and sleep duration 6‒7 h per night were all positively associated with depressive symptoms (all P<0.05). Among junior high, senior high, and vocational high school students, sleep duration ≤5 h per night was positively associated with depressive symptoms (P<0.05). For both Han Chinese and ethnic minority students, irregular breakfast consumption, lack of MVPA, sleep duration less than 8 h per night, and alcohol consumption were all positively associated with depressive symptoms (all P<0.05). ConclusionThe prevalence of depressive symptoms among middle school students in Yunnan Province is comparable to that in central China and higher than that in northern regions. Prevention and control efforts should prioritize female students and those in junior and senior high school stages. Universal improvements in lifestyle behaviors among middle school students, such as regular breakfast consumption, MVPA, sufficient sleep (≥8 h), and abstinence from smoking and alcohol. Particular attention should be given to limiting excessive screen time among junior high school students and addressing the mental health needs of females not living with their parents, senior high school students, and Han Chinese students.

Translocator protein 18 kDa（TSPO），as a key biomarker for neuroinflammation， has attracted widespread attention in the research on the pathogenesis of stroke in recent years. Stroke is a severe neurological disease， in which neuroinflammation plays a crucial role. TSPO exhibits multiple functions in regulating the activation and polarization of microglial cells and modulating neuroprotective responses， making it an important entry point for understanding the pathological mechanism of stroke.With the continuous development of TSPO-PET imaging technology， this technology has been widely used in clinical and experimental studies， providing a powerful tool for real-time monitoring of intracerebral inflammation and evaluation of therapeutic outcomes. This article systematically reviews the research advances in TSPO in neuroinflammation associated with ischemic and hemorrhagic stroke and explores its potential neuroprotective mechanisms and application prospects，in order to provide theoretical support and research directions for the optimization and innovation of stroke treatment strategies in the future.

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.

Objective To investigate the risk factors for postoperative recurrence and metastasis in patients with T1 stageⅢ/Ⅳ clear cell renal cell carcinoma(ccRCC), and to analyze the influence of surgical methods on prognosis, so as to provide prognostic evaluation and treatment guidance for clinical practice. Methods A retrospective analysis was conducted on 398 patients diagnosed with T1 stage Ⅲ/Ⅳ ccRCC who underwent either partial nephrectomy(PN)or radical nephrectomy(RN)at Jiangsu Province Hospital during Jan. 2008 and Sep. 2022. The patients were divided into recurrence group(n=49)and non-recurrence group(n=349)according to whether the tumor recurred during the follow-up period. The general, clinical data and prognosis were compared between the two groups. Univariate and multivariate Cox regression analyses were used to explore the factors influencing disease-free survival(DFS)and overall survival(OS)after surgery. Subgroup analysis using Kaplan-Meier curves was performed for T1a and T1b patients. Results During the median follow-up of 67(42, 98)months, the recurrence group was characterized by older age, larger tumor diameter, higher proportion of T1b stage, and more complex tumor anatomy. Univariate and multivariate Cox regression analyses showed that age ≥55 years and R.E.N.A.L. score ≥7 were independent risk factors for poorer DFS and OS(P＜0.05). Subgroup analysis revealed that PN or RN did not significantly affect DFS or OS in T1a patients and OS in T1b patients, while RN significantly improved DFS in T1b patients(P＜0.05). Conclusion Age ≥55 years and R.E.N.A.L. score ≥7 are independent risk factors for poor DFS and OS in highgrade T1 ccRCC patients. For T1b patients, RN may improve DFS.

ObjectiveTo investigate the clinical efficacy of oral/ gastric tube/ jejunal tube administration or retention enema of Qingjie Huagong Formula （清解化攻方， QHF） mirabilite abdominal bag external application combined with conventional western medicine in patients with acute pancreatitis （AP）. MethodsA prospective， randomized， double-blind， placebo-controlled trial was conducted. A total of 128 AP patients were enrolled and randomly assigned to a control group and a treatment group， with 64 cases in each group. The control group received placebo and conventional western medicine， while the treatment group additionally received oral/ gastric tube/ jejunal tube administration or retention enema of QHF， and mirabilite abdominal bag external application. Both groups received treatment from admission to discharge as one complete course， with the maximum treatment duration not exceeding 14 days.The primary outcome was the severity grading of AP. Secondary outcomes were clinical efficacy， laboratory indicators including white blood cell count （WBC）， C-reactive protein （CRP）， procalcitonin （PCT）， blood urea nitrogen （BUN）， lactate （Lac）， and D-dimer， gastrointestinal function recovery indicators including time to relief of abdominal pain， time to recovery of bowel sounds， and time to resumption of enteral nutrition， total fluid volume administered within 24 h after admission， intra-abdominal pressure， length of hospital stay， hospitalization costs， and incidence of complications. ResultsDuring the treatment period， 3 cases dropped out in the control group and 9 cases in the treatment group， leaving 116 cases for final analysis （55 in the treatment group and 61 in the control group）. After treatment， the markedly effective rate and overall effective rate in the treatment group were 69.09% （38/55） and 92.73% （51/55）， respectively， which was higher than 49.18% （30/61） and 80.33% （49/61） in the control group. The severity of the disease in the treatment group was significantly lower than that in the control group （P＜0.05）. Compared to the control group， the treatment group showed significantly reduced levels of WBC， CRP， PCT， BUN， Lac， and D-dimer； the time to relief of abdominal pain， time to recovery of bowel sounds， and time to resumption of enteral nutrition were significantly shortened； the fluid volume administered within 24 h after admission and intra-abdominal pressure were significantly reduced， as well as the length of hospital stay and hospitalization costs （P＜0.05 or P＜0.01）. The incidences of acute kidney injury， systemic inflammatory response syndrome， and infected pancreatic necrosis in the treatment group were significantly lower than those in the control group （P＜0.05）. ConclusionQHF combined with conventional western medicine can significantly improve the inflammatory status of AP patients， promote gastrointestinal function recovery， reduce intra-abdominal pressure and fluid resuscitation requirements， lower the risk of certain complications， and shorten the length of hospital stay.

Purpose: Approximately 50%-74% of patients with metastatic human epidermal growth factor receptor 2 (HER2)–positive breast cancer do not respond to trastuzumab, with 75% of treated patients experiencing disease progression within a year. The combination of pyrotinib and capecitabine has showed efficacy in these patients. This study evaluates the efficacy and safety of pyrotinib combined with metronomic vinorelbine for trastuzumab-pretreated HER2-positive advanced breast cancer patients. Materials and Methods: In this phase 2 trial, patients aged 18-75 years with HER2-positive advanced breast cancer who had previously failed trastuzumab treatment were enrolled to receive pyrotinib 400 mg daily in combination with vinorelbine 40mg thrice weekly. The primary endpoint was progression-free survival (PFS), while secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety. Results: From October 21, 2019, to January 21, 2022, 36 patients were enrolled and received at least one dose of study treatment. At the cutoff date, 20 experienced disease progression or death. With a median follow-up duration of 35 months, the median PFS was 13.5 months (95% confidence interval [CI], 8.3 to 18.5). With all patients evaluated, an ORR of 38.9% (95% CI, 23.1 to 56.5) and a DCR of 83.3% (95% CI, 67.2 to 93.6) were achieved. The median OS was not reached. Grade 3 adverse events (AEs) were observed in 17 patients, with diarrhea being the most common (27.8%), followed by vomiting (8.3%) and stomachache (5.6%). There were no grade 4/5 AEs. Conclusion Pyrotinib combined with metronomic vinorelbine showed promising efficacy and an acceptable safety profile in HER2-positive advanced breast cancer patients after trastuzumab failure.

Redox imbalances, which result from excessive production of reactive oxygen species (ROS) or malfunctioning of the antioxidant system, are the source of oxidative stress.ROS affects all structural and functional components of cells, either directly or indirectly. In addition to causing genetic abnormalities, excessive ROS also oxidatively modifies proteins by protein oxidation and peroxidation and alters lipid structure via advanced lipoxidation, decreasing function and promoting damage or cell death. On the other hand, low levels of ROS constitute important redox-signaling molecules in various pathways that maintain cellular homeostasis and regulate key transcription factors. As a result, ROS can affect various cellular processes, such as apoptosis, migration, differentiation, and proliferation. ROS can act as signaling molecules, controlling various normal physiological activities at the cellular level. Furthermore, there is an increasing body of evidence indicating the role of ROS in various clinical conditions.In this review, we will summarize the role of ROS in physiological and pathological processes and antioxidant action during oxidative stress.
