Background. ANGPTL8 has been reported to be a regulator of lipid metabolism, and it is associated with insulin resistance (IR) and metabolic syndrome (MetS). We investigated whether ANGPTL8 plays a role in MetS. Methods. ANGPTL8 and adiponectin concentrations were measured in PCOS patients with or without MetS and in their corresponding healthy controls. The association of circulating ANGPTL8 with adiponectin and other parameters was also examined. Results. Circulating ANGPTL8 concentrations were higher in PCOS women with MetS than in those without MetS and in the controls (P<0.01). ANGPTL8 was positively correlated with age, BMI, FAT%, WHR, SBP, TG, FBG, HbA1c, Fins, and HOMA-IR (all P<0.01) in the study populations and negatively associated with adiponectin and M-values (P<0.001). In addition, ANGPTL8 was positively correlated with PRL, LH, TEST, and FAI and negatively correlated with SHBG (all P<0.01). ROC curve analyses showed that the AUCMetS was 0.87 (P<0.001), with a sensitivity of 92.4% and specificity of 75.4%, and the AUCIR was 0.82 (P<0.01), with a sensitivity of 76.4% and specificity of 75.6%. Conclusion. ANGPTL8 levels progressively decrease from PCOS patients with MetS to those without MetS and may be a serum marker associated with the degree of metabolic disorders.
Background Bone morphogenetic protein9 (BMP9) has been reported to have a role in vascular development. However, there is still a lack of information regarding the association between circulating BMP9 levels and cardiovascular disease in humans. The goal of this study is to measure circulating BMP9 concentrations in patients with essential hypertension (HTN), coronary heart disease (CHD) and HTN + CHD, and evaluates the relationship between circulating BMP9 and these cardiovascular diseases. Methods A total of 417 individuals were recruited for this cross-sectional study from June 2015 to December 2017. These subjects were screened for HTN and CHD. Circulating BMP9 concentrations were measured by ELISA. Results Circulating BMP9 concentrations were significantly low in HTN, CHD and HTN + CHD individuals relative to those of the healthy individuals. Circulating BMP9 correlated negatively with SBP, FIns and HOMA- IR in HTN patients and correlated negatively with FBG and 2 h-BG in CHD patients. In both HTN and CHD patients, circulating BMP9 correlated negatively with BMI, WHR, FAT%, BP and TG. Multivariate logistic regression analysis showed that circulating BMP9 levels were associated with HTN, HTN + CHD and CHD. Individuals with low quartile of circulating BMP9 had a significantly high risk of HTN or/and CHD as compared with those in high quartile. Conclusions BMP9 is likely to be a biomarker for cardiovascular disease in humans, and it may play a role in the progression of cardiovascular disease. Trial registration ChiCTR-OPC-14005324 .

Background: To investigate whether lower limb vascular intervention or autologous platelet-rich gel (APG) treatment would benefit diabetic lower extremity arterial disease (LEAD) patients with foot ulcers.Methods: A total of 82 diabetic LEAD patients with foot ulcers were recruited and divided into three groups: group A (30 patients received basal treatment), group B (21 patients received basal and APG treatment), and group C (31 patients received basal and lower limb vascular intervention treatment). All patients underwent routine follow-up visits for 6 months. The baseline characteristics and parameters were examined. After treatment, changes in all parameters from baseline were recorded. The differences between groups and the relationship among each parameter were determined.Results: There were no differences in the ankle brachial index (ABI) or major amputation between groups A and B (P>0.05). Compared with groups A and B, the ABI and major amputation rate of group C were improved (P<0.05). There were no significant differences in transcutaneous oxygen partial pressure (TcPO 2 ), the heal rate or minor amputation between groups A and C (P>0.05). Compared with groups A and C, TcPO 2 , the heal rate and minor amputation of group B were improved (P<0.05). The logistic regression analysis indicated that major amputation was mainly associated with the ABI, and minor amputation was mainly associated with TcPO 2 . Lower limb vascular intervention improves the ABI and reduces major amputation, and APG improves TcPO 2 and reduces minor amputation. Conclusions:In diabetic LEAD patients with foot ulcers, major amputation was mainly associated with the ABI, while minor amputation was mainly associated with TcPO 2 . Interventional surgery (angioplasty) mainly improves the ABI, reduces the incidence of major amputation and improves the macrovasculature, and APG mainly improves local TcPO 2 , reduces the incidence of minor amputation and improves the microcirculation.
Background. Cartilage intermediate layer protein 2 (CILP2) is associated with a variety of plasma lipoproteins and lipid traits. However, the correlation between CILP2 and obesity remains unknown. The aim of this study was to investigate the relationship between circulating CILP2 levels and obesity based on body mass index (BMI). Methods. A total of 252 subjects were divided into three groups: normal weight ( n = 124 ), overweight ( n = 94 ), and obese ( n = 34 ). Metabolic parameters were measured in a fasting state. Serum CILP2 concentration was tested by enzyme-linked immunosorbent assay. Multivariate linear regression analysis was used to explore the relationship between CILP2 and obesity. We also conducted bioinformatics analysis to further explore the genes and signaling pathways related to CILP2. Results. The concentrations of serum CILP2 in the overweight and obese groups were significantly higher than that in the normal weight group. In multiple linear regression analysis, BMI was positively correlated with CILP2 concentration after controlling gender and age. Being overweight and obese were independently correlated with CILP2 concentration after adjusting for gender, age, SBP, DBP, FBG, 2-hour OGTT blood glucose (2h-BG), fasting blood insulin (FIns), TG, TC, HDL-C, LDL-C, and FFA. Bioinformatics analysis showed that the genes related to CILP2 are primarily associated with lipid metabolism and insulin resistance. Conclusion. We speculate that CILP2 may attribute to metabolic disorders in obesity.
Objective To explore the efficacy of the hospital glycemic management system with information integration in patients with malignant tumors and hyperglycemia. Methods Three hundred ninety-three patients diagnosed with malignant tumors with hyperglycemia and hospitalized in the non-endocrinology department of a specialized cancer hospital from March 2019 to November 2020 were recruited. All the patients were diagnosed and treated according to the clinical department and disease course. In total, 196 patients were divided into the control group, who received the conventional blood glucose management mode, and 197 patients were divided into the intervention group, who received the hospital glycemic management system with information integration. The average daily glucose levels were recorded before and after breakfast, lunch, and dinner, at bedtime and at night. The average glucose level, glucose compliance rate, hypoglycemia rate, hyperglycemia rate, glucose measurements per day, average number of hospitalization days and patient satisfaction were compared between the groups. Results In the intervention group, the average glucose level was significantly lower than that in the control group (P<0.05). The hyperglycemia and hypoglycemia rates in the intervention group were lower than those in the control group (P<0.05). The glucose compliance rate in the intervention group was higher than that in the control group (P<0.05). The highest blood glucose level in the intervention group was lower than that in the control group (P<0.05), and the lowest blood glucose level was higher than that in the control group (P<0.05). The glucose measurements per day in the intervention group were higher than those in the control group, and the average number of hospitalization days in the intervention group was lower than that in the control group (P<0.05). Patient satisfaction in the intervention group was higher than that in the control group (P<0.05). Conclusion The hospital glycemic management system with information integration significantly improved the glycemic management of patients with malignant non-endocrine tumors and hyperglycemia, including their glucose level and glucose compliance rate, as well as patient satisfaction, and reduced the average number of hospitalization days and risk of hyperglycemia/hypoglycemia.
