    Objective This study aims to use the cardiometabolic index（CMI）and the LightGBM model to assess the risk of target organ damage（TOD）in metabolic syndrome（MetS）patients，explore its gender-specific associations，and provide a basis for precise intervention．Methods MetS patients meeting diagnostic criteria and healthy individuals（the control group，used only as a baseline reference parameter）were enrolled．The composite endpoint of TOD was defined as cardiorenal damage and macro/microvascular lesions．Core features selected included CMI and age．A LightGBM classification model was constructed（70% training set，30% test set with stratified sampling），and 100 random splits were used for validation to generate the area under the curve（AUC） with 95% confidence interval（CI）and draw the calibration curve．Performance was assessed using AUC，combined with the SHAP algorithm and Partial Dependence Plot（PDP）for interpretability and gender-stratified analysis．Results Baseline comparison showed that the CMI level of MetS patients（6.8±2.3）was significantly higher than that of the control group（3.2±1.1），and the positive rate of TOD（57.6%）was significantly higher than that of the control group（12.0%）（both P＜0.001）．The LightGBM model achieved an AUC of 0.875 in prediction，with CMI as the most important predictive feature（relative contribution of 31.5%），and the interaction test between CMI and gender showed a significant difference（P＜0.01）．CMI showed a non-linear S-shaped association with TOD，with a risk inflection point at 5.7 and a high-risk plateau at 7.5．Significant gender differences were observed：the threshold for accelerated risk in females（CMI 5.0）was earlier than that in males（CMI 6.5）．Conclusions Using healthy individuals as controls clarifies the characteristics of high CMI levels and high TOD risk in MetS patients．The LightGBM-SHAP framework clarifies the core predictive value of CMI．The gender-specific thresholds provide quantitative guidance for formulating personalized early intervention strategies for males and females，demonstrating good potential for clinical application．

代谢综合征属于中医学“肥胖”“消渴”“脾瘅”等范畴,是以多种代谢异常在同一个体集结出现,包括肥胖、高血糖、血脂异常、高血压以及高尿酸血症等为表现的临床综合征。“浊毒”是由于脏腑功能失常,导致机体产生的生理、病理产物不能及时排出,蕴积体内而化生的致病因素。浊毒致病机体多有面色晦浊、腹胀满、小便浑浊、大便黏腻不爽、黄腻苔、滑数脉等表现。浊毒与代谢综合征的发病机制,在微观和宏观上具有对应性。文章从浊毒与代谢综合征的发病机制出发,对其临床治疗的共同点进行了综述。

Metabolic syndrome falls into the categories of obesity,diabetes and spleen disease in traditional Chinese medicine,and is manifested by various metabolic abnormalities in an individual,including obesity,hyperglycemia,dyslipidemia,hypertension and hyperuricemia. The turbid toxin is a pathogenic factor caused by visceral dysfunction,which leads to the accumulation of physiological and pathological wastes that fail to be eliminated from the body in time. People with turbid toxin are manifested by dull and cloudy complexion,abdominal distension,turbid urine,sticky stool,yellow greasy coating,slippery pulse,etc. The turbid toxin corresponds to the pathogenesis of metabolic syndrome at both micro and macro levels. This paper intends to explore the correlations between the turbid toxin and the pathogenesis of metabolic syndrome and make a review with relevant clinical treatment.

Objective To analyze the relationship between C-peptide and metabolic syndrome (MS) in premenopausal and postmenopausal women with type 2 diabetes mellitus (T2DM). Methods A total of 64 premenopausal and postmenopausal T2DM patients in our hospital from March 2019 to March 2021 were included in the experimental group, and 64 healthy women in the same period were selected as the control subjects. Fasting C-peptide, postprandial 2h C-peptide and blood glucose, serum inflammatory factors, blood lipid and blood pressure were detected and compared between the two groups. The incidence of MS was compared between the two groups. The relationship among fasting C-peptide, postprandial 2h C-peptide and blood glucose, serum inflammation, blood lipid and blood pressure were analyzed by Pearson correlation. Results Fasting C-peptide,postprandial 2h C-peptide, 2hPG, FPG, WBC, TNF-a, IL-6, LDL-C, TG, TC, SBP, DBP of the experimental group were higher than those of the control group. HDL-C of the experimental group was lower than that of the control group, P<0.05. The incidence of MS in the experimental group (12.50%) was higher than that in the control group (1.56%), P< 0.05. Fasting C-peptide and postprandial 2h C-peptide were positively correlated with 2hPG, FPG, WBC, TNF-a, IL-6, LDL-C, TG, TC, SBP and DBP, and negatively correlated with HDL-C (P<0.05). Conclusion The metabolic disorder of blood lipid, blood pressure, blood glucose and inflammatory reaction were common in T2DM patients before and after menopause. The increase of C-peptide level would increase the incidence of MS, which should be paid attention in clinic practice.

宫内发育迟缓(IUGR)又称小于胎龄儿(SGA),不仅影响近期健康,且对远期健康和生长发育具有重要影响,成年后2型糖尿病、肥胖、高血压、冠心病等代谢综合征的发病率明显增高。可能的机制是在生命早期个体对不利的刺激高度敏感,产生基因表达的异常,影响内分泌系统,从而对某些器官的结构或功能产生长期或永久性的影响。我们需从做好产前母体的营养与健康管理、小于胎龄儿出生后的系统管理、喂养选择纯母乳喂养等措施减少疾病的发生。

Intrauterine growth retardation (IUGR), also known as the small for gestational age (SGA), not only affects the recent health and has an important influence on long-term health and growth development. They are more easy to get the metabolic syndrome such as adult metabolism of type 2 diabetes, obesity, hypertension, coronary heart disease. Possible mechanism is produced in the early life of individual, is highly sensitive to adverse stimuli gene expression abnormalities which affecting the endocrine system, thus it have a long-term or permanent impact on the structure and function of some organs. We need to do more in prenatal maternal nutrition and health management, system management of SGA infants, pure breast feeding. Thus these could reduce the occurrence of metabolic syndrome.

瘦素是维持人体能量代谢平衡的蛋白质,在人体中主要由白色脂肪组织分泌,通过与瘦素受体结合发挥作用。近年来有许多与瘦素相关的研究证明高血压患者及代谢综合征患者的血清瘦素水平较健康人群明显升高。两种疾病均可出现心室肥厚,蛋白尿,动脉粥样硬化等表现,说明二者存在共同的靶器官。瘦素代谢异常可出现瘦素抵抗并通过影响肾素-血管紧张素-醛固酮系统(renin angiotensin aldosterone system, RAAS)及炎症细胞因子来损伤靶器官。本文旨在总结瘦素在高血压及代谢综合征中的作用机制,并探讨瘦素对高血压合并代谢综合征靶器官损伤作用的研究进展。

Leptin is a protein that maintains the balance of energy metabolism in human body. It is mainly secreted by white adipose tissue in human body. In recent years, many studies have shown that the serum leptin level in patients with hypertension complicated with metabolic syndrome is significantly higher than that of healthy people. Both of the diseases can lead to left ventricular hypertrophy, proteinuria, atherosclerosis and other manifestations. The abnormal metabolism of leptin may contribute to leptin resistance which damages target organs by affecting the angiotensin aldosterone system and inflammatory cytokines. The aim of this article is to summarize the mechanism of leptin in hypertension and metabolic syndrome, and to explore its effect on the target organ damage in patients with hypertension complicated with metabolic syndrome.

Objective To study the prevalence and correlation between the metabolic syndrome MS (including hypertension, diabetes, hyperlipidemia and obesity) with cardiovascular and dementia in the elderly people of south China. Methods This cross-sectional research studied metabolic syndrome of the elderly in south China. We collected the demographics and chemotic data and compared them in MS and non-MS group. And Logistic regression was used to analyze the independent factor of MS and the relationship between MS and the cardiovascular disease and dementia. Results This study included 206 patients and 92 (44.66%) of them were diagnosed as MS. 35 patients (38.04%) in MS group were female and 28 female cases (24.56%) in non-MS group. The mean age of the sample was (86.74±6.10) and the comparison between the MS group (86.37±5.74) and non-MS group (87.04±6.38) was not significantly different. White blood cell (WBC) (7.46±2.38 vs 6.46±2.35,P=0.003) and serum creatinine (Scr) was significantly [94.50(68.50,129.33) vs 78.00(64.50, 99.75),P=0.004]in MS group versus in non-MS group. Single factor and Multinomial logistic regression found WBC, serum creatinine and female gender were the independent risk factors of MS. Myocardial infarction (35, 38.04%) and angina (28, 24.56%) were significantly higher in MS group than that in non-MS group (10, 8.77%) and (39, 34.21%), respectively, with P<0.05. Logistic regression found MS was an independent risk factor of myocardial infarction and angina but not in heart failure and stroke. Dementia (including Alzheimer disease and vascular dementia) was found lower in MS group (26, 28.26%) than that in non-MS group (50, 43.86%), the difference was significant and this means MS could be protective for dementia. Conclusion MS is prevalent in the elderly of south China. Female gender, WBC and Scr were independent factors of MS; MS was the independent risk factor of myocardial infarction and angina; dementia was significantly lower in MS group, implying MS could be protective to dementia.
