BACKGROUND:Psoralen has a strong anti-osteoporotic activity and may have a restorative effect on chemotherapy-induced osteoporosis. OBJECTIVE:To explore the restorative effect of psoralen on the osteogenic differentiation of bone marrow mesenchymal stem cells in mice inhibited by cyclophosphamide and its mechanism. METHODS:C57BL/6 mouse bone marrow mesenchymal stem cells were isolated and cultured.Effect of psoralen on viability of bone marrow mesenchymal stem cells was detected by MTT assay.Osteogenic induction combined with alkaline phosphatase staining was used to determine the optimal dose of psoralen to restore the osteogenic differentiation of bone marrow mesenchymal stem cells inhibited by cyclophosphamide.The mRNA expression levels of Runx2,alkaline phosphatase,Osteocalcin,osteoprotegerin,and Wnt/β-catenin signaling pathway-related genes Wnt1,Wnt4,Wnt10b,β-catenin,and c-MYC were measured by RT-qPCR at different time points under the intervention with psoralen.The protein expression of osteogenic specific transcription factor Runx2 and Wnt/β-catenin signaling pathway related genes Active β-catenin,DKK1,c-MYC,and Cyclin D1 was determined by western blot assay at different time points under the intervention with psoralen. RESULTS AND CONCLUSION:(1)There was no significant effect of different concentrations of psoralen on the viability of bone marrow mesenchymal stem cells.The best recovery of the inhibition of osteogenic differentiation of bone marrow mesenchymal stem cells caused by cyclophosphamide was under the intervention of psoralen at a concentration of 200 μmol/L.(2)Psoralen reversed the reduction in osteogenic differentiation marker genes Runx2,alkaline phosphatase,Osteocalcin and osteoprotegerin mRNA expression and Runx2 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium.(3)Psoralen reversed the decrease in Wnt/β-catenin pathway-related genes Wnt4,β-catenin,c-MYC mRNA and Active β-catenin,c-MYC,and Cyclin D1 protein expression and the increase in DKK1 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium.(4)The results showed that cyclophosphamide inhibited osteogenic differentiation of bone marrow mesenchymal stem cells in mice,and psoralen had a restorative effect on it.The best intervention effect was achieved at a concentration of 200 μmol/L psoralen,and this protective effect might be related to the activation of Wnt4/β-catenin signaling pathway by psoralen.

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.

Aim To investigate the predictive value of the Murray law-based quantitative flow ratio(μQFR)after target vessel pretreatment for vascular-related adverse events in patients with de novo coronary lesions treated with drug-coated balloon.Methods This retrospective study included 223 lesions from 223 patients who underwent drug-coated balloon-only strategy and completed 2-year clinical follow-up.Coronary angiographic images of target vessels pre-procedure,post-balloon and post-procedure were collected,and analyzed using a novel Murray's law-based algorithm.The μQFR analysis of each target vessel included not only the μQFR value of the target vessel,but also the length of the target vessel,the degree of vessel diameter stenosis,the reference lumen diameter,the minimum lumen diameter and blood flow velocity.The primary endpoint was defined as the postoperative vessel-oriented composite endpoint(VOCE).Results During the2-year clinical follow-up period,a total of 25 patients(11.2%)experienced VOCE events.Com-pared with the control group,patients with VOCE events after pretreatment showed a decrease in μQFR(P<0.001).Multivariate Logistic analysis showed that a lower target vessel μQFR after pretreatment(OR=0.931,95%CI:0.894～0.969,P<0.001)was an independent predictor of VOCE events.ROC curve analysis showed that the cut-off value for predicting 2-year VOCE events using preprocessed μQFR was 0.83(95%CI:0.727～0.840),with a sensitivity of 72.7%and a specificity of 84.0%(AUC=0.773,95%CI:0.676～0.870,P<0.001).Survival analysis showed that compared with patients with μQFR>0.83,patients with μQFR≤0.83 had a significantly higher incidence of VOCE events at 1 and 2 years,increasing to 3.909 times(16.9%vs.4.6%,HR=3.909,95%CI:1.539～9.930,P=0.004)and 2.867 times(19.7%vs.7.2%,HR=2.867,95%CI:1.301～6.316,P=0.009).After adjusting for potential con-founds,patients with pretreated μQFR≤0.83 had a 2.567 times in 2-year incidence of VOCE events(HR=2.567,95%CI:1.151～5.727,P=0.021)and a 3.712 times in 1-year incidence of VOCE events(HR=3.712,95%CI:1.478～9.810,P=0.006)compared to patients with good pretreatment.Conclusions For patients with in situ coronary artery disease,a lower μQFR after pretreatment increases the risk of postoperative adverse clinical events.μQFR≤0.83 may be used to evaluate the effectiveness of lesion pretreatment.

OBJECTIVE To comprehensively evaluate the efficacy， safety and cost-effectiveness of insulin icodec in treating type 2 diabetes mellitus （T2DM）， providing evidence-based guidance for new drug selection in hospital and clinical medication decision-making. METHODS PubMed， Cochrane Library， Embase， CNKI， Wanfang， VIP and foreign health technology assessment （HTA） websites were searched by using rapid health technology assessment from inception to 15 July 2025 for systematic reviews/meta-analyses， pharmacoeconomic studies， and HTA reports on insulin icodec in the treatment of T2DM. After data extraction and quality assessment， the findings of the included studies were analyzed descriptively. RESULTS Ten systematic reviews/meta-analyses and three pharmacoeconomic studies were included. Among them， 4 systematic reviews/meta-analyses were of high quality； the overall quality of the 3 pharmacoeconomic studies was relatively good. Regarding efficacy， insulin icodec was superior to once-daily basal insulin in reducing glycated hemoglobin （HbA1c） and in achieving the target of HbA1c＜7% （P＜0.05）. No significant differences were observed between icodec insulin and comparators in lowering fasting plasma glucose （P＞0.05）. For safety， insulin icodec did not increase the incidence of any adverse events （AEs）， serious AEs， clinically significant hypoglycemia （random glucose＜3 mmol/L）， injection-site reactions， or allergic reactions， compared with once-daily basal insulin overall （P＞ 0.05）； however， insulin icodec was associated with a significant increase in body weight （P＜0.05）. Domestic economic evaluations indicated that insulin icodec was more cost-effective than insulin glargine and insulin degludec when its annual costs were in the range of 784.90-1 145.96 and 597.66-736.34 US dollars， respectively. CONCLUSIONS Insulin icodec demonstrates favorable efficacy and safety profiles in the treatment of T2DM； however， attention should be paid to the risk of weight gain. Under China’s healthcare system， insulin icodec demonstrates greater economic value only when the patient’s weekly required basal insulin dose falls within a specific range，and clinical practice requires individualization.

Objective:To evaluate the cosmetic effect of facial melanocytic nevus excision along the pigmented contours.Methods:A total of 318 patients with facial melanocytic nevi were collected from the Department of Burns and Plastic Surgery, the Affiliated Yongchuan Hospital of Chongqing Medical University from October 2018 to August 2020. The patients collected after October 2019 underwent contoured excision of facial melanocytic nevi (observation group), while those collected before October 2019 underwent fusiform excision of lesions (control group). Recurrence rates, wound lengths, and scar conditions were compared between the two groups one year after surgery. Comparisons of measurement data between the two groups were conducted using the t test. Results:The observation group included 159 patients (372 melanocytic nevi), comprising 24 males and 135 females, aged from 15 to 45 (25.4 ± 6.5) years; the short diameters of the melanocytic nevi ranged from 2 to 6 (3.9 ± 0.6) mm, and the long diameters ranged from 2 to 8.5 (4.3 ± 0.7) mm. The control group consisted of 159 patients (390 melanocytic nevi), including 29 males and 130 females, aged from 16 to 48 (26.3 ± 7.3) years; the short diameters of the melanocytic nevi ranged from 2 to 6 (3.7 ± 0.8) mm, and the long diameters ranged from 2.2 to 8.4 (4.5 ± 0.5) mm. There were no significant differences in age, gender composition, or short and long diameters of the melanocytic nevi between the two groups (all P > 0.05). After one year of follow-up, 4 patients experienced recurrence in the observation group, and 3 experienced relapse in the control group; the scar scores were 0.64 ± 0.24 points in the observation group and 0.58 ± 0.19 points in the control group, and there were no significant differences in the recurrence rates or scar scores between the two groups (both P > 0.05) ; the increase in wound length was significantly lower in the observation group (27.44% ± 8.46%) than in the control group (48.42% ± 38.84%, t = 10.19, P = 0.004) . Conclusion:Compared with the fusiform excision technique, the pigmented contoured excision technique showed similar efficacy for the treatment of facial melanocytic nevi, but resulted in shorter wound lengths.

Tripartite motif-containing (TRIM) family proteins are crucial E3 ubiquitin ligases that have garnered significant attention for their regulatory roles in bone metabolism in recent years. This article reviews the function and regulatory mechanisms of TRIM family proteins in bone metabolism, focusing on their dual roles in bone formation and resorption. It also provides a detailed analysis of signaling pathways and molecular mechanisms by which TRIM family members regulate the activities of osteoblasts and osteoclasts. Research findings suggest that modulating the expression or activity of TRIM family proteins could be beneficial for treating bone diseases such as osteoporosis. This review highlights the molecular mechanisms of TRIM family members in bone physiology and pathology, aiming to provide theoretical basis and scientific guidance for developing novel therapeutic strategies for bone diseases.

According to the principle and current domestic and international construction processes of core outcome set(COS) and the characteristics of post-stroke aphasia, this study built COS with evidence-based support for traditional Chinese medicine(TCM) treatment of post-stroke aphasia. Firstly, a comprehensive review was conducted on the articles about the TCM treatment of post-stroke aphasia that were published in the four major Chinese databases, three major English databases, and three clinical registration centers over the past five years. The articles were analyzed and summarized, on the basis of which the main part of the COS for clinical research on the TCM treatment of post-stroke aphasia was formed. Secondly, clinical doctors and related nursing personnel were interviewed, and important outcome indicators in the clinical diagnosis and treatment process were supplemented to form a pool of core outcome indicators. Two rounds of Delphi surveys were carried out to score the importance of the core outcome indicators in the pool. Finally, a consensus meeting of experts was held to establish the COS for clinical research on the TCM treatment of post-stroke aphasia. The final COS included a total of 268 studies [236 randomized controlled trials(RCTs), 21 Meta-analysis, and 11 clinical registration protocols] and 20 open questionnaire survey results. After two rounds of Delphi surveys, a total of 14 outcome indicators and their corresponding measurement tools were included in the expert consensus meeting. The final expert consensus meeting determined the COS for post-stroke aphasia, which included 9 indicator domains and 12 outcome indicators.

This study investigates the genetic diversity and evolutionary relationships of different Artemisia argyi germplasm resources to provide a basis for germplasm identification, variety selection, and resource protection. A total of 192 germplasm resources of A. argyi were studied, and EST-based simple sequence repeat(EST-SSR) primers were designed based on transcriptomic data of A. argyi. Polymerase chain reaction(PCR) amplification was performed on these resources, followed by fluorescence capillary electrophoresis to detect genetic diversity and construct DNA fingerprints. From 197 pairs of primers designed, 28 pairs with polymorphic and clear bands were selected. A total of 278 alleles were detected, with an average of 9.900 0 alleles per primer pair and an average effective number of alleles of 1.407 2. The Shannon's diversity index(I) for the A. argyi germplasm resources ranged from 0.148 1 to 0.418 0, with an average of 0.255 7. The polymorphism information content(PIC) ranged from 0.454 5 to 0.878 0, with an average of 0.766 9, showing high polymorphism. Cluster analysis divided the A. argyi germplasm resources into three major groups: Group Ⅰ contained 136 germplasm samples, Group Ⅱ contained 45, and Group Ⅲ contained 11. Principal component analysis also divided the resources into three groups, which was generally consistent with the clustering results. Mantel test results showed that the genetic variation in A. argyi populations was to some extent influenced by geographic distance, but the effect was minimal. Structure analysis showed that 190 germplasm materials had Q≥ 0.6, indicating that these germplasm materials had a relatively homogeneous genetic origin. Furthermore, 8 core primer pairs were selected from the 28 designed primers, which could distinguish various germplasm types. Using these 8 core primers, DNA fingerprints for the 192 A. argyi germplasm resources were successfully constructed. EST-SSR molecular markers can be used to study the genetic diversity and phylogenetic relationships of A. argyi, providing theoretical support for the identification and molecular-assisted breeding of A. argyi germplasm resources.

OBJECTIVE: Circadian rhythm disruption (CRD) is a risk factor that correlates with poor prognosis across multiple tumor types, including hepatocellular carcinoma (HCC). However, its mechanism remains unclear. This study aimed to define HCC subtypes based on CRD and explore their individual heterogeneity. METHODS: To quantify CRD, the HCC CRD score (HCCcrds) was developed. Using machine learning algorithms, we identified CRD module genes and defined CRD-related HCC subtypes in The Cancer Genome Atlas liver HCC cohort (n = 369), and the robustness of this method was validated. Furthermore, we used bioinformatics tools to investigate the cellular heterogeneity across these CRD subtypes. RESULTS: We defined three distinct HCC subtypes that exhibit significant heterogeneity in prognosis. The CRD-related subtype with high HCCcrds was significantly correlated with worse prognosis, higher pathological grade, and advanced clinical stages, while the CRD-related subtype with low HCCcrds had better clinical outcomes. We also identified novel biomarkers for each subtype, such as nicotinamide n-methyltransferase and myristoylated alanine-rich protein kinase C substrate-like 1. CONCLUSION We classify the HCC patients into three distinct groups based on circadian rhythm and identify their specific biomarkers. Within these groups greater HCCcrds was associated with worse prognosis. This approach has the potential to improve prediction of an individual's prognosis, guide precision treatments, and assist clinical decision making for HCC patients.
