Objective: To analyze the prevalence status and clustering patterns of risk factors for chronic diseases among adult residents in Rui' an City, Zhejiang Province, so as to provide a basis for formulating strategies for the prevention and control of chronic diseases and implementing risk factor interventions. Methods: A multi-stage random cluster sampling method was used to select residents aged ≥18 years in 5 townships (sub-districts) of Rui' an City as survey subjects from December 2023 to March 2024. Data on basic information, history of major chronic diseases, lifestyle behaviors, height, weight, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. Descriptive analysis was used to analyze the prevalence status of 5 risk factors for chronic diseases. K-means clustering analysis was used to analyze clustering patterns. Results: A total of 3 060 people were surveyed, including 1 476 males, accounting for 48.24%, and 1 584 females, accounting for 51.76%. The median age was 49.00 (interquartile range, 25.00) years. There were 1 275 cases (41.67%) of hypertension, 462 cases (15.10%) of diabetes, and 1 460 cases (47.71%) of dyslipidemia. Insufficient fruit and vegetable intake, excessive salt intake, overweight and obesity, excessive red meat intake, and smoking involved 2 201, 1 878, 1 541, 1 337, and 571 people, with prevalences of 71.93%, 61.37%, 50.36%, 43.69%, and 18.66%, respectively. K-means clustering analysis identified 4 clustering patterns: smoking-insufficient fruit and vegetable intake type (249 people, accounting for 8.20%), low intake type (1 421 people, accounting for 46.75%). high red meat type (245 people, accounting for 8.07%), and high BMI-high salt type (1 118 people, accounting for 36.96%). The prevalences of hypertension and diabetes were higher in adult residents of the high BMI-high salt type, at 56.53% and 20.30%, respectively. The prevalence of dyslipidemia was higher in adult residents of the smoking-insufficient fruit and vegetable intake type, at 59.44%. Conclusions The prevalence of insufficient fruit and vegetable intake among adult residents in Rui' an City is relatively high. The clustering pattern of chronic disease risk factors is dominated by the low intake type. The prevalence of chronic diseases is higher in adult residents of the high BMI-high salt type and smoking-insufficient fruit and vegetable intake type. It is suggested to carry out health education and collaborative intervention of risk factors for different risk groups.

BACKGROUND:Triptolide,a bioactive component of the traditional Chinese medicine Tripterygium wilfordii,has a certain protective effect on neurons.OBJECTIVE:To investigate the effect of triptolide on cerebral ischemia/reperfusion injury.METHODS:(1)Cell experiment:Hippocampal neurons(HT22 cells)were randomly divided into control group,glucose oxygen deprivation/reoxygenation(OGD/R)group,OGD/R+triptolide group,OGD/R+triptolide+si-TIGAR group,OGD/R+si-TIGAR group,and OGD/R+triptolide+rapamycin group.HT22 cell viability was detected by cell counting kit 8.Tp53-induced glycolysis and apoptosis factors,glutathione peroxidase 4,7 members of the solsolic vector family 11,sphingosine kinase 1(SPHK1)and(mTOR)were detected by western blot assay.Glutathione,malondialdehyde and iron level were detected using the biochemical kit.(2)Animal experiment:Rats were randomly divided into sham surgery group,model group,and triptolide group.Cerebral artery occlusion/reperfusion rat models were prepared in the latter two groups.Rats in the triptolide group were orally administered 50 mg/kg triptolide for 7 days.Twenty-four hours after administration,LONGA method was used to evaluate the neurological impairment of rats,TTC method was used to observe the conditions of cerebral infarction,TUNEL staining was used to detect cell apoptosis,and western blot was performed to detect the expression level of related proteins.RESULTS AND CONCLUSION:(1)At the cellular level,triptolide promoted cell viability and inhibited apoptosis in HT22 cells treated with OGD/R.Triptolide also increased the expression levels of Tp53-induced glycolysis and apoptosis factors,glutathione peroxidase 4,and 7 members of the solsolic vector family 11,activated the SPHK1/mTOR pathway,increased glutathione content,inhibited malondialdehyde content and iron levels.Rapamycin treatment counteracted the protective effect of triptolide on HT22 cells.(2)At the animal level,triptolide significantly reduced neurological deficits,infarct volume,and cell apoptosis,and inhibited neuronal ferroptosis in brain tissue of rats.To conclude,triptolide can inhibit ferroptosis by upregulating the expression level of Tp53-induced glycolysis and apoptosis factors and activating the SPHK1/mTOR signaling,and thereby reduced cerebral ischemia/reperfusion injury.These findings suggest that triptolide may be a candidate drug for the treatment of cerebral ischemia/reperfusion injury.

Objective To investigate the malignant phenotypic characteristics of NIH/3T3 cells induced by hexavalent chromium compound under three-dimensional (3D) culture conditions. Methods NIH/3T3 cells in the logarithmic growth phase were divided into four groups: two-dimensional (2D) control group, 2D transformation group, 3D control group, and 3D transformation group. The 2D control group underwent conventional culture, while the 3D control group was cultured with Matrigel. The 2D and 3D transformation groups were exposed to hexavalent chromium compound at a concentration of 0.25 mg/L based on their respective control conditions. Malignant transformation of NIH/3T3 cells was assessed using a soft agar colony formation assay. Malignant phenotypes were evaluated through assays of cell proliferation, apoptosis, cell cycle, wound healing, Transwell migration, and Transwell invasion. Results Cells in both the 2D and 3D transformation groups exhibited anchorage-independent growth, indicating successful malignant transformation. The colony formation rate of cells in the 3D transformation group was higher than that in the 2D transformation group [(6.17±1.31)% vs (1.00±0.41)%, P<0.01]. Compared with the 3D control group, cell proliferation, apoptosis rate, and migration cell count decreased [(100.00±0.00)% vs (95.01±3.49)%, (9.32±0.43)% vs (7.12±0.40)%, (62.50±11.27) vs (48.33±7.31), all P<0.05], while invasion cell count increased [(57.17±9.68) vs (122.83±15.41), P<0.05], and the relative migration area at 12, 24, and 48 hours also increased in 3D transformation group [(4.32±2.09)% vs (10.75±0.45)%, (5.87±1.32)% vs (11.47±0.99)%, (8.74±1.34)% vs (11.79±0.93)%, all P<0.05]. The proportions of cells in G0/G1, S, and G2/M phases between the 3D transformation and 3D control groups had no significant differences (all P>0.05). Conclusion Hexavalent chromium compounds induce key malignant phenotypes in NIH/3T3 cells, including anchorage-independent growth, reduced apoptosis, and enhanced migratory and invasive capacities.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

ObjectiveTo address the shortage of high-caliber multidisciplinary professionals in China's rehabilitation engineering field and the prominent issue of "separation between medicine and engineering" in existing curricula, this study introduces the World Health Organization rehabilitation competency framework (RCF) to construct a systematic curriculum system for rehabilitation engineering. MethodsGuided by the four core competency domains of RCF (practice, professionalism, learning and development, management and leadership) and their associated supporting knowledge, the rehabilitation engineering curriculum was restructured into a modular framework, piloted and validated within the Biomedical Engineering (Intelligent Robotics) program at University of Health and Rehabilitation Sciences. ResultsA four-tiered curriculum system comprising General Education-Disciplinary Platform-Professional Core-Diverse Electives with a total of 160 credits was established, achieving precise mapping between competency objectives and course content. The students in the pilot cohort demonstrated outstanding academic performance (50% ranked in the top ten of their major), they also gained a deeper understanding and mastery of interdisciplinary knowledge integrating medicine and engineering. ConclusionThe RCF-based curriculum system effectively promotes the organic integration of medical and engineering knowledge, providing an internationally aligned competency-oriented paradigm for rehabilitation engineering talent cultivation, which holds significant value for broader application.

Objective To exploring the effect of inflammatory indicators on the outcome of assisted conception of in vitro fertilization/intracytoplasmic sperm injection(IVF/ICSI)in patients with ovarian endometriosis(OEM).Methods The study subjects were selected as the patients with OEM who received IVF/ICSI treatment at the Third Affiliated Hospital of Zhengzhou University from January 2019 to February 2024.Based on whether previous surgery for uterine endometriosis cyst removal had been performed,they were divided into non-surgery group(n=73)and surgery group(n=112).To explore the differences in inflammatory markers between two groups and to determine whether they have an impact on the outcome of assisted reproduction.Results The lymphocytes(L)and blastocyst formation rates of patients in surgery group were significantly higher than those in non-surgery group,platelet to lymphocyte ratio(PLR)and carbohydrate antigen 125(CA125)were significantly lower than those in non-surgery group(P＜0.05).There were no statistically significant differences in the clinical pregnancy rate and live birth rate between two groups of patients(P＞0.05).After adjusting for confounding factors,the results of multivariate Logistic regression analysis showed that L,PLR,and CA125 had no statistically significant impact on the clinical pregnancy rate and live birth rate(P＞0.05).Both maternal age and the number of embryos transferred exerted a certain influence on clinical pregnancy rates and live birth rates(P＜0.05),furthermore,the type of embryo transferred had a significant effect on clinical pregnancy rates(P＜0.05).Conclusion Compared with non-surgery group,surgery group had higher L level and lower PRL and CA125 levels,but these changes did not significantly affect clinical pregnancy or live birth outcomes in OEM patients undergoing IVF/ICSI assisted reproduction.

Objective:To evaluate the relationship between the neutrophil-to-lymphocyte ratio (NLR) during the perioperative period and early postoperative recurrence in patients with advanced gastric cancer.Methods:In this prospective study, 188 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-75 yr, with a body mass index of 20-30 kg/m 2, with radiological staging of T 2-4N xM 0, underwent elective gastric cancer radical surgery under general anesthesia at the Fourth Hospital of Hebei Medical University from January 2018 to April 2022, were selected. The NLR was measured at 1 day before operation and postoperative days 1, 3 and 5. The difference between postoperative and preoperative NLR (ΔNLR) was calculated. Based on the presence or absence of tumor recurrence and/or metastasis within 2 yr after surgery, the patients were divided into recurrence group and non-recurrence group. The Cox proportional hazards regression model was employed to evaluate the early postoperative recurrence and perioperative NLR in patients with advanced gastric cancer. Results:A total of 171 patients ultimately completed the follow-up. There were 77 cases in recurrence group and 94 in non-recurrence group. Compared to non-recurrence group, NLR and ΔNLR were significantly increased on the 5th day after operation in recurrence group ( P<0.05). The elevated NLR and ΔNLR at postoperative day 5 were independent risk factors for recurrence within 2 yr in patients with advanced gastric cancer ( HR=1.026, P<0.05). Conclusions:NLR may not be associated with the risk of early postoperative recurrence in the patients with advanced gastric cancer, and further evaluation with large-scale studies is needed.

Objective:To investigate the preventive effect of a subanesthetic dose of esketamine on emergence agitation (EA) in pediatric patients undergoing fracture fixation surgery under general anesthesia.Methods:This study was a randomized, double-blind, placebo-controlled trial. Eighty-two pediatric patients, aged 3-6 yr, with American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective closed reduction and internal fixation of humeral fractures at the People′s Hospital of Fuyang City from March 2023 to August 2024, were divided into 2 groups ( n=41 each) using simple random sampling: esketamine group (group E) and control group (group C). Group E received an intravenous injection of esketamine at a dose of 0.3 mg/kg before anesthesia induction, while the equal volume of normal saline was given instead in group C. The induction and maintenance of general anesthesia were the same in both groups. The drug was discontinued after operation and the children were transferred to the post-anesthesia care unit. The primary outcome was the occurrence of EA assessed using the Pediatric Anesthesia Emergence Delirium scale. Secondary outcome measures included the acceptance of the facemask during anesthesia induction, the rate of propofol use during the emergence period, the Children′s Hospital of Eastern Ontario Pain Scale scores at awakening and at 2 and 6 h postoperatively, the requirement for rescue analgesia in the emergence period, and the occurrence of adverse reactions. Results:Compared with group C, the incidence of EA [38% (15/39) vs. 15% (6/40)] was significantly decreased, the usage rate of propofol during the emergence period was decreased, the degree of acceptance of the facemask during anesthesia induction was increased, and Children′s Hospital of Eastern Ontario Pain Scale scores at all time points and the rate of rescue analgesia in the emergence period were decreased in group E ( P<0.05). There was no statistically significant difference in the incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:Administering a subanesthetic dose of esketamine before anesthesia induction can reduce the risk of EA in pediatric patients undergoing fracture fixation surgery under general anesthesia and raise the the quality of recovery with a high safety.
