Objective: To explore the relationship of non suicidal self injury (NSSI) with anhedonia and dysfunctional attitudes in children and adolescents with depression, in order to provide a basis for the prevention and treatment of NSSI patients. Methods: A total of 157 children and adolescents with depression admitted to Wuhan Psychosomatic Hospital from February 2023 to February 2025 were enrolled and divided into an NSSI group(36 cases) and a non NSSI group (121 cases), according to the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. The Childhood Trauma Questionnaire-Short Form (CTQ-SF) Chinese version of Dimensional Anhedonia Rating Scale (DARS) and the Chinese version of Dysfunctional Attitude Scale-A (DAS-A) were utilized to evaluate the childhood trauma, anhedonia and dysfunctional attitude scores, respectively. Spearman correlation analysis was used to analyze the relationship between NSSI and DARS, DAS-A scores. Multivariable Logistic regression analysis was performed to examine the relationship of NSSI with childhood trauma, DARS and DAS-A scores in children and adolescents with depression. Results: The incidence rate of NSSI of children and adolescents was 22.93%. The proportions of childhood trauma and major depression in NSSI group (58.33% and 61.11%) were higher than those in non NSSI group (35.54% and 41.32%), with statistical differences ( χ 2=5.79, 4.38, both P <0.05). The total score of DAS-A with (188.41±35.27) in NSSI group was higher than in non NSSI group (140.21±30.62), while the scores across DARS dimensions (hobbies, food/drinks, social activities, sensory experiences) and total DARS score (5.37±1.22, 6.96±1.48, 7.13±2.02, 12.06±3.15, 30.19±7.43) were significantly lower than those in the non NSSI group (9.04±2.25, 10.16±2.43, 10.97±2.62, 14.51±4.08, 44.16±12.51),with statistical differences ( t =8.00, -9.37, -7.49, -8.10, -3.32, -6.37, all P <0.01). The NSSI in children and adolescents with depression was positively correlated with childhood trauma, severity of depression and DAS-A total score, and negatively correlated with DARS total score ( r =0.21, 0.63, 0.54, -0.50, all P <0.05). After adjusting for severity of depression, multivariate Logistic regression analysis revealed that childhood trauma, total scores of DARS and DAS-A were all correlated factors for the occurrence of NSSI in children and adolescents with depression ( OR =1.52, 1.48, 1.96, all P <0.05). Conclusion The risk of NSSI in children and adolescents with depression is relatively high, and NSSI is closely related to anhedonia, dysfunctional attitudes and childhood trauma.

OBJECTIVE To investigate the prevalence and influencing factors of potentially inappropriate medication （PIM） among the elderly in nursing homes in Urumqi based on three PIM screening tools， and to compare the applicability of different tools. METHODS A cross-sectional study design was adopted. Elderly individuals from six nursing homes in Urumqi were selected as the research subjects from May 2021 to September 2023. Demographic characteristics， disease burden and medication records of the elderly were collected. PIM screening was performed using the Chinese PIM criteria （2024 edition）， the American Geriatrics Society （AGS） Beers criteria （2023 edition）， and the Screening Tool of Older Person’S Prescriptions（STOPP）/Screening Tool to Alert to Right Treatment（START） （2023 edition）. Fleiss’s Kappa test was used to assess the consistency among the three screening tools， and multivariate Logistic regression was used to analyze the influencing factors of PIM. RESULTS The prevalence of PIM screened by the Chinese PIM criteria was 47.4% （323/682）， by the AGS Beers criteria was 43.4% （296/682）， and by the STOPP criteria was 50.9% （347/682）. The consistency among the three screening tools was low （Fleiss’s Kappa＝0.12， P ＜0.001）. Multivariate Logistic regression analysis showed that all three screening tools indicated that polypharmacy， aspirin use and psychotropic drug use were independent risk factors for PIM among elderly in nursing houses （all OR＞1， P ＜0.05）. CONCLUSIONS The prevalence of PIM among the elderly in nursing homes in Urumqi is relatively high. Polypharmacy， aspirin use and psychotropic drug use are common independent risk factors for PIM. There are differences in screening results among the three tools with low consistency. The Chinese PIM criteria can serve as a first-line tool for PIM screening in nursing homes.

Objective: To systematically review the modeling strategies, primary outcomes, and quantifiable effects in animal models of transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), acute hemolytic transfusion reaction (AHTR), and related transfusion paradigms. Subgroup meta-analysis was designated as the primary analytical framework, with the overall pooled effect treated as exploratory. Methods: We searched PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception to December 30, 2025. Eligible studies utilized animal models to simulate transfusion-related adverse reactions and provided extractable quantitative outcomes. The SYRCLE tool was used to assess the risk of bias. Random-effects models were employed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Prespecified subgroup analyses were conducted for TRALI, TACO, AHTR, and donor sex-related transfusion paradigms. Additional analyses included funnel plots, Egger/Begg tests, leave-one-out sensitivity analyses, and meta-regression based on publication year. Results: Twenty-one studies comprising 24 independent comparisons were included in the quantitative synthesis. The overall pooled estimate was OR=1.07 (95% CI:0.69-1.66), with substantial heterogeneity (I =96%). Subgroup analyses yielded the following estimates: TRALI, OR=0.83 (95%CI:0.57-1.21, I =97%); TACO, OR=1.85 (95%CI:0.54-6.34, I =93%); donor sex-related paradigms, OR=1.49 (95%CI:1.02-2.17, I =85%); and AHTR, OR=0.26 (95%CI:0.10-0.64, I =0%). Between-subgroup differences were statistically significant (P<0.000 1). Publication year was positively correlated with effect size (P=0.001 4). Most studies demonstrated unclear risk of bias across several SYRCLE domains due to incomplete methodological reporting. Conclusion: Animal models of transfusion-related adverse reactions exhibit significant structural heterogeneity across syndrome categories. Therefore, subgroup-specific and narrative syntheses are recommended as the primary presentation framework, rather than relying on a single overall pooled effect. Complement-targeted interventions in AHTR models demonstrated a consistent protective signal. In contrast, TRALI and TACO models require greater standardization in modeling protocols and endpoint definitions to reduce methodological variability.

Background: The treatment landscape for melanoma, a particularly malignant skin cancer, is constrained by notable drug resistance and toxicity. β-Asarone, a natural compound from Acorus tatarinowii, has shown anticancer potential. Disruption of calcium homeostasis and mitochondrial dysfunction are key regulators of tumor cell survival and death. Objective: This research was conducted to investigate the impact of β-Asarone on B16F10 melanoma cells, focusing on its potential to induce apoptosis by modulating calcium signaling and mitochondrial function. Methods: Cell proliferation and apoptosis were evaluated using CCK-8, colony formation, EdU, and TUNEL assays. Intracellular calcium levels and mitochondrial membrane potential were measured using Fluo-4 AM, Rhod-2 AM, and JC-1 staining. Reactive oxygen species (ROS) generation and adenosine triphosphate (ATP) levels were assessed by fluorescent probes and ATP assay. Western blotting was utilized to detect apoptosis-related proteins, AMP-activated protein kinase (AMPK) pathway activation, and mitochondrial dynamics (OPA1, DRP1, FIS1). Results: Treatment with β-Asarone notably inhibited the proliferation of B16F10 cells while simultaneously inducing apoptosis. Fluorescent probe analysis revealed that β-Asarone triggered cytosolic and mitochondrial Ca 2+ overloaded in both the cytosol and mitochondria, accompanied by decreased mitochondrial membrane potential, elevated ROS levels, and reduced ATP production. Western blot analysis showed increased expression of DRP1 and FIS1, decreased OPA1, and enhanced AMPK phosphorylation, indicating that β-Asarone promotes mitochondrial fission through AMPK activation, likely driven by intracellular calcium imbalance. Conclusion This study demonstrates that β-Asarone induces apoptosis in B16F10 melanoma cells by triggering Ca 2+ overload and mitochondrial dysfunction.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Objective To analyze the current status of clinical trial registration of common anorectal diseases in Chinese Clinical Trial Registry(ChiCTR)and the research of TCM.Methods The ChiCTR database was retrieved to collect and organize clinical trials related to hemorrhoids,anal fissures,anal fistulas,perianal abscesses,and perianal eczema.The retrieval time was from the establishment of the database to December 10,2023.Characterization of included registration trials was analyzed.Results A total of 148 registered projects were included,75 of which were TCM-related clinical trials.Among them,134 clinical trials were pre-registered and 121 passed the ethical review.Shanghai,Jiangsu,Guangdong,Beijing and Sichuan accounted for 76.35％of the total number of registrations,and the largest number of registered projects was in Shuguang Hospital affiliated with Shanghai University of Traditional Chinese Medicine.The top 3 funding sources were local finance,self-funding and hospital funding.The registered projects were mainly intervention studies.114 studies used randomized methods and 34 studies were blinded.Conclusion At present,the number of ChiCTR-registered clinical trials on anorectal diseases is on an increasing trend,and the treatment of anorectal diseases with TCM has obvious characteristics.However,there are cases of irregular filling of registration content and uneven regional distribution.

Objective To investigate the effect of heated povidone iodine solution on pain intensity and ulcer healing in patients with chronic venous leg ulcer after debridement and dressing change.Methods A total of 58 patients with chronic venous leg ulcer who first visited outpatients and wards of Department of Cardiovascular Surgery,Department of Burns and Department of Plastic Surgery of The First Affiliated Hospital of Naval Medical University from Jun.1,2023,to Jun.1,2024 were enrolled and randomly assigned to heated group(using 38 ℃ povidone iodine solution for debridement and flushing,n=29)or normal group(using 24 ℃ povidone iodine solution for debridement and flushing,n=29).The general baseline data of the 2 groups were compared,the pain intensity and wound bed temperature before and after debridement and dressing change were evaluated,and the change of pressure ulcer scale score for healing during the observation period and ulcer healing rate were observed.Results There were no significant differences between the 2 groups in age,gender,smoking,body mass index,whether the ulcer exudates,infection,duration of ulcer,ulcer area,pressure ulcer scale score for healing or analgesic use within 24 h(all P＞0.05).There was no significant difference in pain intensity between the 2 groups before or after dressing change and debridement(both P＞0.05).The pain intensity during debridement in the heated group was lower than that in the normal group(P＜0.05).There was no significant difference in the temperature of wound bed before flushing between the 2 groups(P＞0.05).The temperature of wound bed in the heated group was significantly higher than that in the normal group immediately after flushing and at the end of debridement and dressing change(P＜0.01,P＜0.05).The pressure ulcer scale score for healing in the heated group showed a trend of being lower than that in the normal group during the observation period,and the ulcer healing rate was significantly higher than that in the normal group(P=0.033,hazard ratio=0.452,95％confidence interval 0.217-0.941).Conclusion In patients with chronic venous leg ulcer,the use of heated povidone iodine solution can reduce the pain intensity during dressing change and debridement,maintain the stability of wound bed temperature,and promote the healing of ulcer.

Objective To investigate the association between intestinal microbiota dysbiosis and colonic polyps,Helicobacter pylori(Hp)infection,and intestinal metaplasia.Methods A total of 200 patients diagnosed with colonic polyps,Hp infection,or both conditions.These patients were classified into three groups:the colonic polyp group(n=90),the Hp infection with intestinal metaplasia group(n=49),and the colonic polyp combined with Hp infection and intestinal metaplasia group(n=61).Additionally,62 individuals who underwent routine health examinations at our hospital during the same period were enrolled as a control group.The study compared gut microbiota imbalances across these groups to investigate the association between intestinal dysbiosis and colonic pol-yps,Hp infection,and the co-occurrence of colonic polyps with Hp-related intestinal metaplasia.Logistic regression analysis was performed to identify risk factors associated with the development of intestinal metaplasia due to Hp infection in patients with colonic polyps.Results Compared to the control group,intestinal flora imbalance was significantly more prevalent in the colorectal polyp group,the Hp infection with intestinal metaplasia group,and the colorectal polyp combined with Hp infection and intestinal metaplasia group(P<0.05).Moreover,intestinal flora imbalance in the colorectal polyp with Hp infection and intestinal metaplasia group was significantly higher than that in both the colorectal polyp group and the Hp infection with intestinal metaplasia group(P<0.05).Regarding exhaled gas levels,H2 and CH4 concentrations were significantly elevated in the groups with colorectal polyps accom-panied by Hp infection and intestinal metaplasia,those with colorectal polyps alone,and those with Hp infection and intestinal metaplasia,compared to the control group(P<0.05).Similarly,exhaled H2S levels were significantly higher in the group with colorectal polyps complicated by Hp infection and intestinal metaplasia than in the control group(P<0.05).Furthermore,exhaled H2 and CH4 levels showed positive correlations with the presence of colorectal polyps,Hp infection with intestinal metaplasia,and colorectal polyps combined with Hp infection and intestinal metaplasia(P<0.05).Exhaled H2S levels were positively correlated with colorectal polyps complicated by Hp infec-tion and intestinal metaplasia(P<0.05).Logistic regression analysis indicated that a history of smoking,atrophic gastritis,peptic ulcer,and intestinal flora imbalance are independent risk factors for Hp infection-associated intesti-nal metaplasia in patients with colorectal polyps(P<0.05).Conclusion Intestinal flora imbalance is associated with colorectal polyps and Hp-induced intestinal metaplasia,suggesting that microbial dysbiosis may represent a potential risk factor for the development of these conditions.

Objective:To analyze the epidemiological characteristics and infection sources of cholera in China from 2005 to 2024.Methods:A total of 2 066 cholera cases were included in the study, which were obtained from the China Disease Control and Prevention Information System (CDPCIS) of China CDC. The information on cholera clusters was downloaded from the National Public Health Emergency Event Surveillance System (PHEESS) of China CDC. A total of 128 cholera clusters were included and analyzed in this study. The epidemiological characteristics and infection sources of cholera were analyzed. The Jointpoint model was applied to analyze the incidence trend, and annual percentage change (APC) was also quantified.Results:From 2005 to 2024, a total of 2 066 cholera cases were reported, with an average of 103 cases reported annually. Specifically, the incidence showed a marked downward trend from 2004 to 2015 ( APC=-26.78%, P=0.006). During 2015-2024, the disease remained at low endemic levels, with an average of 18 reported cases annually ( APC=-2.68%, P=0.807). Cholera peak season was from May to October. A total of 24 provinces reported cholera cases, which were mainly distributed in Zhejiang, Fujian, Beijing, Jiangsu, Anhui, Guangdong, and Hainan provinces, accounting for 78.03% of the total cases. Pathogen surveillance indicated an alternating prevalence of Vibrio cholerae serogroups O1 and O139 among laboratory-confirmed cases between 2005 and 2024. There was a disparity in the dominant serogroup of Vibrio cholerae by region. The results from 128 cholera clusters indicated that cholera outbreaks frequently occurred in rural banquets (64.84%), followed by regular restaurants (13.28%). Among these, 63 clusters (49.22%) with identified infection sources indicated that foodborne transmission (95.24%) was the primary mode of cholera transmission, which mainly through seafood and aquatic products, such as soft-shelled turtles, shrimp and shellfish. The characteristics of cholera clusters caused by Vibrio cholerae serogroups O1 and O139 showed statistically significant differences in scale, attack rate, place of residence, setting, and infection source ( P<0.05). Conclusion:Cholera incidence has remained consistently low since 2015 in China, mainly in sporadic cases. Rural gatherings (e.g., wedding banquets) are the main settings for cholera clusters. The main infection sources are predominantly caused by cross-contamination due to improper processing practices of aquatic products, such as soft-shelled turtles.

Objective To explore the efficacy of precise surface positioning method in percutaneous screw fixation for Jones fracture.Methods Data of 46 patients with Jones fractures admitted to our hospital from September 2021 to December 2023 were retrospectively analyzed.According to the different treatment methods,the patients were divided into screw groups(24 patients fixed by percutaneous screws)and tension band groups(22 patients fixed by incision and reset tension band).The general conditions,follow-up time,surgical time,hospitalization time,fracture reduction quality,postoperative complete weight-bearing time,fracture healing time,and complications in the two groups were recorded and compared.The American Association of Foot and Ankle Surgery(AOFAS)system was used to assess the recovery of foot function.Results There was no statistically significant difference in the general data before the operation between the two groups of patients(P＞0.05).The follow-up time of the two groups was 6 to 24 months.Compared with the tension band group,the screw group had shorter operation time[(32.96±5.35)min vs.(47.27±9.42)min],shorter hospitalization time[(5.75±1.18)d vs.(7.68±2.05)d],earlier postoperative complete weight-bearing time[(6.47±0.73)w vs.(7.29±1.66)w],faster fracture healing time[(3.31±0.68)months vs.(4.29±1.29)months],higher AOFAS score[(89.13±2.62)vs.(79.59±4.49)](all P＜0.05).The tension band group of fracture reduction quality was better than the screw group(P＜0.05).The quality of fracture reduction during the operation in the tension band group was better than that in the screw group(P＜0.05).In terms of complications:no complications occurred in the screw group,one patient in the tension band group developed infection,and one patient had a loose Kirchner needle.Conclusion Precise surface positioning method in percutaneous screw fixation for Jones fracture is a safe and effective method with precise positioning,simple operation,small trauma,and rapid rehabilitation,which is worthy of clinical promotion,but the indications need to be strictly controlled according to the type of fracture.
