Objective·To construct truncations of CYLD,and to preliminarily analyze their effects on the proliferation of gastric cancer cells.Methods·TCGA,GTEx,and Kaplan-Meier Plotter databases were used to analyze the differences in the expression levels of CYLD between gastric cancer tissues and normal tissues,and their relationship with the prognosis of gastric cancer patients.Immunohistochemistry and Western blotting were used to detect the expression of CYLD in cancer tissues and adjacent noncancerous tissues.Western blotting and qRT-PCR were used to analyze the protein and mRNA expression levels of CYLD in gastric mucosal epithelial cells and gastric cancer cells.According to the sequence and structural characteristics of CYLD gene,primers were designed to construct its truncations.Their expression was detected and identified by agarose gel electrophoresis and Western blotting,and localization was observed by immunofluorescence.In the human gastric adenocarcinoma cells(AGS)with CYLD knockdown,blank NC was added to the control group,and the full-length CYLD,enzyme-inactivated mutant,and three truncated plasmids were added to the experimental group.The proliferation changes of cells in each group were detected by CCK-8 and plate cloning assays.Co-immunoprecipitation,deubiquitination,and Western blotting assays were performed to examine the binding ability of full-length CYLD,the enzyme-inactivated mutant,and the truncated variants to CAMK2A,the level of CAMK2A deubiquitination,and the expression of STAT3 and p-STAT3 proteins.Results·CYLD expression in normal gastric tissues and cells was significantly higher than in gastric cancer tissues and cells,and the prognosis of patients with high expression of CYLD was better.The truncations of human CYLD were successfully constructed,and full length CYLD,enzyme-inactivated mutant,and truncations were mainly localized in the cytoplasm.Knockdown of CYLD in gastric cancer cells significantly enhanced the proliferative ability of gastric cancer cells.Reconstitution of CYLD-knockdown cells with CYLD-WT,or truncated variants containing the CAP3 or USP domains significantly inhibited the proliferation of gastric cancer cells.In addition,CYLD bound to CAMK2A mediated K63 deubiquitination modification,and inhibited CAMK2A-induced phosphorylation of STAT3.Conclusion·The human CYLD truncation plasmids are successfully constructed,and the full length CYLD and its CAP3 and USP segments significantly inhibit the proliferation of gastric cancer cells.

Alzheimer's disease (AD) is a common neurodegenerative disorder among the elderly, and BuChE has emerged as a potential therapeutic target. In this study, we reported the development of compound 8e, a selective reversible BuChE inhibitor (eqBuChE IC50 = 0.049 μmol/L, huBuChE IC50 = 0.066 μmol/L), identified through extensive virtual screening and lead optimization. Compound 8e demonstrated favorable blood-brain barrier permeability, good drug-likeness property and pronounced neuroprotective efficacy. Additionally, 8e exhibited significant therapeutic effects in zebrafish AD models and scopolamine-induced cognitive impairments in mice. Further, 8e significantly improved cognitive function in APP/PS1 transgenic mice. Proteomics analysis demonstrated that 8e markedly elevated the expression levels of very low-density lipoprotein receptor (VLDLR), offering valuable insights into its potential modulation of the Reelin-mediated signaling pathway. Thus, compound 8e emerges as a novel and potent BuChE inhibitor for the treatment of AD, with significant implications for further exploration into its mechanisms of action and therapeutic applications.

Objective:
To investigate the prevalence levels and trends of overweight and obesity among adult residents in Zhejiang Province from 2015 to 2023, so as to provide a basis for developing regional weight management strategies.
Methods:
Permanent residents aged ≥18 years from Zhejiang Province who participated in the China Chronic Disease and Risk Factor Surveillance Project in 2015, 2018, and 2023 were selected as survey subjects. Data on sociodemographic information, height, weight and waist circumference were collected through questionnaire surveys and physical examinations. The prevalence of overweight, obesity, and central obesity were calculated and standardized using data from the Seventh National Population Census of Zhejiang Province in 2020. The Cochran-Armitage trend test was employed to analyze the trends in prevalence of overweight, obesity, and central obesity across different genders, ages and regions.
Results:
A total of 23 902 individuals were surveyed, comprising 10 985 males (45.96%) and 12 917 females (54.04%). Participants were aged ≥60 years, with 13 088 individuals accounting for 54.76%. There were 9 388 urban residents (39.28%) and 14 514 rural residents (60.72%). The standardized prevalence of overweight among residents increased from 30.05% in 2015 to 33.98% in 2023, the standardized prevalence of obesity increased from 7.67% to 15.22%, and the standardized prevalence of central obesity increased from 22.81% to 33.82%, all showed upward trends (all P<0.05). In 2015, 2018, and 2023, the standardized prevalence of overweight was higher in males than in females. In 2018 and 2023, the standardized prevalence of obesity and central obesity were higher in males than in females (all P<0.05). From 2015 to 2023, the standardized prevalence of overweight, obesity, and central obesity among both males and females showed upward trends (all P<0.05). In 2015, 2018 and 2023, the prevalence of central obesity showed an increasing trend with age (all P<0.05). From 2015 to 2023, upward trends were observed in the prevalence of overweight, obesity, and central obesity among residents aged 18-<45 years and aged ≥60 years, as well as in the prevalence of obesity and central obesity among residents aged 45-<60 years (all P<0.05). In 2015, 2018 and 2023, the standardized prevalence of overweight obesity were higher in urban areas than in rural areas, while the standardized prevalence of central obesity was lower in urban areas (all P<0.05). From 2015 to 2023, the standardized prevalence of overweight, obesity, and central obesity among both urban and rural areas showed upward trends (all P<0.05).
Conclusion
From 2015 to 2023, the prevalence of overweight, obesity, and central obesity among adult residents in Zhejiang Province showed increasing trends, with variations in prevalence levels and trends observed across genders, ages, and urban / rural areas.

This study explores the diagnosis and treatment of needle knife therapy for ankylosing spondylitis (AS) at middle and advanced stage based on the theory of meridian tendons, from a holistic perspective and syndrome differentiation. The treatment strategy includes "harmonizing yin and yang" to address root causes and "tendons-based release" to harmonize qi and blood, with the "tendons nodule points" as the core acupoint selection criterion. Based on this approach, the study systematically elaborates on two needle knife methods for AS: "governor vessel bone-piercing technique" and "below-the-umbilicus release technique", covering indications, acupoint location, and procedures. Clinical case examples are provided to enrich needle knife therapy guided by the theory of meridian tendons, offering insights for clinical and research work on AS.

Objective:To investigate the clinical characteristics of children with Chikungunya fever.Methods:This retrospective cohort study analyzed clinical data of 91 children with Chikungunya fever at the Department of Pediatrics, Foshan women and Children Hospital between July 2025 and August 2025. The patients were divided into four groups based on onset-age: 0-<1 year, 1-<3 years, 3-<6 years, and 6-14 years. One-way ANOVA and chi-square tests were used to compare the clinical features of children with Chikungunya fever at different ages.Results:Among the 91 children with chikungunya fever, 55 were male and 36 were female, with an onset age of 6 (2, 11) years, age groups comprised 0-<1 year (10 cases), 1-<3 years (13 cases), 3-<6 years (17 cases) and 6-14 years (51 cases). Fever occurred in 87 cases (96%), with 50 cases (57%) had high fever. Skin rash was observed in 89 cases (98%), and 60 cases (67%) had a generalized rash. Joint pain was reported in 57 cases (63%), among which 35 cases (61%) had pain in two or more locations, with the knee involved in 21 cases (37%), the ankle in 15 cases (26%), and the wrist in 6 cases (11%).The knee was the most commonly affected joint 21 cases (37%), followed by the ankle 15 cases (26%) and wrist 6 cases (10%). Joint ultrasound was performed in 31 cases (34%), all showed joint effusion, including 8 cases (26%) without complaints of joint pain. The incidence of high fever was significantly lower in the 3-<6 years and 6-14 years groups compared to the 0-<1 year group (both P<0.05). The 6-14 years group also had a lower incidence of high fever than the 1-<3 years group ( P<0.05). The 1-<3 years group had longer duration of fever than the 3-<6 years and 6-14 years groups (both P<0.05). The incidence of joint pain was higher in the 3-<6 years and 6-14 years groups compared to the 1-<3 years group (both P<0.05), and higher in the 6-14 years group than in the 3-<6 years group ( P=0.007). Among all 91 children, 22 cases (24%) had abnormal liver function, 49 cases (54%) showed elevated lactate dehydrogenase (LDH), and 2 cases (2%) had elevated creatine kinase. The proportions of elevated aspartate aminotransferase (AST) and LDH were higher in the 0-<1 year and 1-<3 years groups compared to the 3-<6 years and 6-14 years groups (all P<0.05). Conclusions:The clinical characteristics of children with Chikungunya fever vary among children of different ages. Children in the 0-<3 years are more prone to high fever with longer duration and generalized maculopapular rash, while the children in the 6-14 years have have a higher proportion of joint pain, and joint ultrasound revealed effusion in all examined children. AST and LDH levels are elevated in the 0-<3 years groups.

Objective:
To analyze the disease burden and risk factors of colorectal cancer in Zhejiang Province from 1990 to 2019, so as to provide the basis for prevention and control of colorectal cancer.
Methods:
Based on data of 2019 Global Burden of Disease (GDB 2019), disease burden and risk factors of colorectal cancer in Zhejiang Province from 1990 to 2019 was assessed using years of life lost (YLL), years lived with disability (YLD), disability-adjusted life years (DALY).
Results:
In 2019, the YLL rate, YLD rate and DALY rate caused by colorectal cancer in Zhejiang Province were 496.15/105, 31.81/105 and 527.96/105, respectively. From 1990 to 2019, the YLL rate, YLD rate and DALY rate caused by colorectal cancer in Zhejiang Province increased by 114.90%, 482.60% and 123.38%, respectively, showing increasing trends (average annual percent change values were =2.663, 6.283 and 2.800, respectively,all P<0.05). From 1990 to 2019, the YLL rate, YLD rate and DALY rate in the age groups of 15 to 49 years, 50 to 69 years and 70 years and older showed increasing trends (all P<0.05). In 1990, the top ten risk factors for colorectal cancer in Zhejiang Province were diet low in calcium, diet low in milk, diet low in whole grains, smoking, alcohol use, low physical activity, high fasting plasma glucose, diet high in red meat, diet low in fiber and high body mass index. In 2019, the top ten risk factors for colorectal cancer in Zhejiang Province were diet low in milk, diet low in whole grains, diet low in calcium, alcohol use, diet high in red meat, high body mass index, high fasting plasma glucose, low physical activity, diet low in fiber and diet high in processed meat.
Conclusions
The disease burden of colorectal cancer in Zhejiang Province showed an upward trend from 1990 to 2019. The top ten risk factors for colorectal cancer remained between 1990 and 2019, while there was a slight change in ranking.

AIM: To compare the efficacy of intravitreal injection of ranibizumab(IVR)and intravitreal injection of conbercept(IVC)in children with retinopathy of prematurity(ROP).METHODS: Retrospective study. A total of 1 100 eyes with ROP treated with intravitreal anti-VEGF at our hospital from January 2015 to June 2023 were included. According to the different therapeutic drugs, the children were divided into two groups: IVR group and IVC group. According to the degree of ROP, the patients were divided into three groups: aggressive ROP(A-ROP), Zone Ⅰ type 1 ROP and Zone Ⅱ type 1 ROP. The reactivation and retreatment between the two groups were compared after propensity score matching(PSM)analysis, and they were followed-up for at least 3 mo after surgery.RESULTS: In Zone Ⅱ type 1 ROP, there was a statistically significant difference in the rates of reactivation and retreatment between the IVR and IVC groups(P<0.05); however, in A-ROP and Zone I type 1 ROP, there were no statistically significant differences in the rates of reactivation and retreatment between the two groups(P>0.05). The risk of reactivation and retreatment of Zone I type 1 ROP was higher than the Zone II type 1 ROP. Furthermore, the use of drugs and corrected gestational age of first treatment were influencing factors of lesion recurrence and retreatment.CONCLUSION: There is a significant difference in the initial cure effect between the two drugs in Zone II type 1 ROP, with the reactivation and retreatment rates of the IVC group being much lower than those of the IVR group.
