目的探讨体质量与腰围对超重肥胖成年人的静态和动态平衡功能的影响。方法采用整群随机抽样方法抽取在中山大学附属第三医院内分泌降糖减重门诊就诊的患者（n = 103），对所有参与者进行基本资料的采集和记录、生化检测、体质量、腰围（WC）和身高测量，静态平衡功能评估采用平衡误差评分系统（BESS）及动态平衡功能评估采用功能性伸展测试（FRT）。对所有参与者的BESS评分和FRT距离根据不同身体指数（BMI）分级和WC分级分别进行组间对比。采用单因素及多元线性回归的方法对参与者静态和动态平衡功能的影响因素分别进行分析。结果① 随BMI分级增加，BESS评分呈上升趋势（P = 0.004），正常WC者的BESS评分低于中心性肥胖者（P < 0.001），结果显示与BMI正常者比较，超重和肥胖者的静态和动态平衡能力差；② 随BMI分级，增加FRT距离呈下降趋势（P P < 0.001），结果显示中心性肥胖者与WC正常者比较，中心性肥胖者的静态和动态平衡能力更差；③ BMI超重组中，随WC增加FRT距离降低，中心性肥胖者与WC正常者组间差异有统计学意义（P = 0.02），结果显示BMI无差异情况下，与正常WC比较，中心性肥胖者的动态平衡能力更差。④ BESS评分与BMI（B = 4.12，P = 0.027， 95% CI = 0.48-7.75）和WC（B = 3.47，P = 0.046， 95% CI = 0.07-6.88）的影响显著，FRT距离与BMI（B = -5.68，P = 0.001， 95% CI = -8.95-2.41）和WC（B = -4.71，P = 0.003， 95% CI = -7.83- -1.61）的影响显著，结果显示肥胖者随BMI增加其静态和动态平衡能力更差，中心性肥胖者比WC正常者的静态和动态平衡能力更差。结论腰围是超重肥胖者的动态和静态平衡功能的独立影响因素，在相同BMI情况下，中心性肥胖者比腰围正常者的动态平衡功能差，其跌倒风险更高。

In terms of the theoretical calculation of surface energy for the rare metal Yttrium (Y) with hexagonal close-packed structure, earlier reports failed to predict the precise results. Here, a logical method was employed to evaluate the surface energy of Y (0001) surface, and the obtained value (1. 141 J/M²) is well consistent with the experimental outcome (1. 125 J/M²). Subsequently, the behaviors of Y (0001) surface adsorbing NO at different sites, i. e. hollow (H1, H2, and H3), bridge (B), and top (T) sites were investigated theoretically. It was found that hollow site H1 has a great ability to adsorb NO molecule, of which the adsorption energy is over 5 eV. Meanwhile, a remarkable elongation of N-O distance (about 24%) at H1 site is observed, coupled with the NO molecule being at the surface parallelly. A variation range of N-O elongation for all adsorption sites is from 0. 2Å (T) to 0. 42Å (H1). This theoretical extension of NO at H1 site is obviously more than those of NO being adsorbed on other transition metal surface. [ABSTRACT FROM AUTHOR]

Objective To investigate the clinical manifestations, endoscopic characteristics, and prognostic factors of patients with colorectal extranodal NK/T cell lymphoma. Methods The clinical data of 52 patients with colorectal extranodal NK/T cell lymphoma admitted to the First Affiliated Hospital of Zhengzhou University from January 2013 to January 2023 were retrospectively analyzed. Their clinical manifestations and endoscopic characteristics were summarized, and the prognostic factors were analyzed by Cox regression model. Results Among the 52 patients with colorectal extranodal NK/T cell lymphoma, there were 35 males and 17 females, with a male-to-female ratio of 2.06∶1. Among the general symptoms, abdominal pain was the most common (39 cases), and B symptoms occurred in 47 patients, among which fever was the most common lymphoma B symptom (42 cases), and gastrointestinal perforation was the most common complication (18 cases). Forty-three patients underwent colonoscopy, and the main manifestations under endoscopy were the ulceration type (24 cases). The ulcers were irregular at the edges and often covered with moss at the bottom. The median survival time was 4.3 months. Multivariate Cox regression analysis showed that hemocytic syndrome (HR=8.50, 95% CI: 1.679-8.328, P=0.001), serum albumin (HR=3.59,95% CI: 1.017-6.551, P=0.048), and with or without chemotherapy (HR= 0.31, 95% CI: 0.246-1.061, P=0.025) were independent factors influencing the overall survival of patients with colorectal extranodal NK/T cell lymphoma. Conclusions Colorectal extranodal NK/T cell lymphoma is a rare disease with a very poor prognosis. When patients present with abdominal pain and lymphoma B symptoms, and when ulcers with irregular edges and moss covering the bottom are found under endoscopy, the disease should be considered, and endoscopic biopsy should be taken in time for pathological diagnosis. The prognosis of patients with hemophagocytic syndrome and hypoproteinemia is poor. This disease should be treated with chemotherapy and surgery, and on this basis, hemophagocytic syndrome and hypoproteinemia should be treated to improve the prognosis of patients.

AIM: To explore the mechanism of rhubarb sugar pills（ RSP） in preventing and treating inflammatory response in large blood vessels of Zucker diabetic fatty（ ZDF） rats based on phosphatidylinositol 3-kinase（ PI3K）-protein kinase B（ PKB/Akt）/nuclear factor-κB（ NF-κB） signaling pathway. METHODS: Fifteen male ZDF（ fa/+） rats were used as the control group, and 75 male ZDF （fa/fa） rats fed with high-fat diet were randomly divided into model group, high-, medium- and low-dose RSP groups, and metformin group, with 15 rats in each group. After 12 weeks of drug intervention, the rats were euthanized, and the serum levels of high-density lipoprotein cholesterol（ HDL-C）, low-density lipoprotein cholesterol （LDL-C）, triglyceride （TG） and total cholesterol （TC） were measured. The serum levels of CD4, interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） were detected by ELISA. The pathological changes of abdominal aorta tissue was observed by HE staining. Immunohistochemistry was conducted to assess the expression of monocyte chemoattractant protein-1 （MCP-1） in the abdominal aorta. The mRNA expression of PI3K, Akt and NF-κB p65 in the abdominal aorta was measured by RT-qPCR. Western blot was utilized to observe the protein levels of PI3K, Akt, p-Akt, p-IκB and NF-κB p65 in the abdominal aorta. RESULTS: Compared with model group, RSP significantly reduced fasting blood glucose, LDL-C, TG and TC levels in diabetic rats （P<0. 05）, and elevated HDL-C levels （P<0. 05 or P<0. 01）. Treatment with RSP also significantly decreased the expression of inflammatory mediators in the serum of diabetic rats, with significant decreases in IL-6, TNF-α and CD4 levels （P<0. 05 or P<0. 01）. The pathological damage in the abdominal aorta tissue was significantly reduced, and the mRNA and protein levels of PI3K, Akt and NF-κB p65, as well as MCP-1, p-Akt and p-IκB protein levels, were all significantly decreased after RSP intervention （P<0. 05 or P<0. 01）. CONCLUSION: Treatment with RSP can lower blood sugar and regulate lipids, thereby alleviating inflammatory damage in large blood vessels of diabetic rats. The mechanism may be related to the inhibition of PI3K-Akt/NF-κB signaling pathway activation and the attenuation of inflammatory response. [ABSTRACT FROM AUTHOR]
