Objective:To investigate the relationship between cumulative fasting blood glucose(cumFPG)exposure and all-cause mortality.Methods:The prospective cohort study included 56 845 subjects of Kailuan Group who participated in physical examinations from 2006 to 2007, 2008 to 2009, and 2010 to 2011 with complete data and a median of 7.77 years of follow up. The end point event was all-cause mortality. The incidence of all-cause mortality was compared in various groups divided by four quartile of cumFPG. The Cox proportional hazards model and natural spline were used to analyze the effect of cumFPG on all-cause mortality.Results:During the average(7.77±1.05)years of follow-up, the incidence density of all-cause mortality was on the rise with the increase of cumFPG(4.93, 5.87, 8.48, and 14.02 per 1 000 person-years), with statistically significant difference by Log- rank test( P<0.001). Cox proportional hazards model showed that after adjusting for potential confounding factors(age, sex, body mass index, hypertension, baseline fasting plasma glucose), the HR value(95% CI)of all-cause mortality in the fourth quartile group was 1.28(1.15-1.42)compared to the first quartile. When cumFPG increased every standard deviation, the risk of all-cause mortality increased by 17%. Natural spline analysis exhibited a similar J curve relationship between cumFPG and all-cause mortality. Conclusion:High cumFPG is a risk factor of all-cause mortality.

Objective:To explore the association between suboptimal health status (SHS) and plasma IgG N-glycans levels among undergraduates in a college in Shandong Province.Methods:A case-control study was conducted from September to November 2017, 100 college students who underwent physical examinations at Weifang University in Shandong, were selected as study participants based on the inclasion and exclusion criteria of the study. According to the criteria of SHS, the participants were divided into an SHS group ( n=50) and a health control group ( n=50). Plasma IgG N-glycosylaton levels were analyzed by means of ultra-high liquid chromatography (UPLC), and 24 glycan peaks were obtained. The Mann-Whitney U-test and binary logistic regression analysis were performed to investigate the association between IgG N-glycans and SHS. P<0.05 was considered statistically significant. Receiver operating characteristic (ROC) curve analyses were used to evaluate the possibility of plasma IgG N-glycans being a biomarker of SHS. Results:The results of univariate and multivariate analysis showed that GP17 was associated with SHS ( P<0.05), and the relative abundance of initial glycan peaks (GP17) was higher in the SHS group compared with the control group. ROC curve analysis showed that the area under the curve (AUC) of the baseline model was 0.826 (95% confidence interval [ CI]: 0.747-0.905, P<0.001); the AUC of the glycan-based model was 0.631 (95% CI: 0.519-0.744, P=0.002), and the AUC of the combined model was 0.848 (95% CI: 0.763-0.912, P<0.001). Compared with the baseline model, the diagnostic efficiency of the combined model revealed a trend of improvement. Conclusions:The SHS of the students in a college in Shandong Province was associated with an IgG N-glycan level of GP17, which was significantly higher than that of the control group.

Objective:To explore the effect of systolic blood pressure (SBP) trajectories on cancers.Methods:The relevant data of 54, 888 employees of Kailuan (Group) Limited Liability Company who participated in the 3 health examinations from 2006-2007, 2008-2009, 2010-2011 were collected and the new onset cancer cases were recorded. The systolic blood pressure trajectory grouping was carried out using the blood pressure measurement values of the 3 physical examinations. The life table method was used to calculate the incidence of cancer, and the multivariate Cox proportional hazard regression model was used to analyze the influence factors of cancer.Results:According to the systolic blood pressure trajectory, 54, 888 subjects were divided into 5 groups, including 14, 326 in the low-stable group, 25, 630 in the moderate-stable group, 5, 390 in the moderate-increasing group, 6, 438 in the elevated-lowering group, and 3, 104 in the elevated-stable group. A total of 1, 070 new onset cancer occurred during the follow-up period of (4.95±0.53) years. The incidence of cancer in the low-stable group, moderate-stable group, moderate-increasing group, elevated-lowering group and elevated-stable group were 1.3% (177/14, 326), 2.2% (491/25, 360), 3.1% (147/5, 390), 2.7% (156/6, 438) and 3.8% (99/3, 104), respectively, the difference was statistically significant ( P<0.001). After adjusting for gender, age, smoking, drinking, physical exercise, body mass index (BMI), fasting blood glucose, total cholesterol, antihypertensive drugs, hypoglycemic drugs, and lipid-lowering drugs, multivariate Cox regression analysis showed that the systolic blood pressure trajectory was related to the incidence of cancer. Compared with the low-stable group, the Hazard ratio ( HR) in the moderate-stable group, moderate-increasing group, elevated-lowering group and elevated-stable group were 1.413, 1.731, 1.557 and 1.907, respectively (all P<0.001). Conclusion:High systolic blood pressure trajectories is the risk factor for cancer.

OBJECTIVE:To investigate the effect of atorvastatin calcium on the carotid intima-media thickness(IMT)and other related indicators in patients with metabolic syndrome(MS). METHODS:The data of 1 444 patients with MS were retrospectively analyzed and randomly divided into observation group(874 cases)and control group(570 cases)by different medication. All patients were given healthy lifestyle,antihypertensive,hypoglycemia and lowering blood lipid guidance. On this basis,treatment group was orally given atorvastatin calcium 20 mg,once every evening. The follow-up was conducted for 3 years. The clinic data in 2 groups was compared,including body mass index(BMI),waist circumference(WC),systolic blood pressure(SBP),diastolic blood pressure (DBP),pulse pressure(PP),IMT,total cholesterol(TC),triglyceride(TG),low conspired lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C),high-sensitivity C-reactive protein(hs-CRP),fasting plasma glucose(FPG)and incidence of adverse reactions before and after treatment. RESULTS:After treatment,compared with before and control group,the BMI、WC、SBP、DBP、PP、IMT、TC、TG、LDL-C、HDL-C、hs-CRP and FPG in observation group were significantly improved,only TG、LDL-C and HDL-C in control group were significantly improved,the differences were statistically significant(P<0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Based on the conventional treatment,atorvastatin calcium can effectively improve the IMT and blood lipid,blood pressure and blood glucose of patients with MS,with good safety.

Objective To investigate the change of high sensitivity c-reaction protein( hs-CRP)on carotid artery plaque. Methods A total of 5 852 individuals were selected as our subjects who randomly stratified from the health examination survey participants in Tangshan Kailuan Company community during 2006 - 2007. A total of 5 440 people(age above 40 years old,free of stroke,transient ischemic attack(TIA)and myocardial infarction ) were qualified and enrolled in the final analysis. A questionnaire survey,blood biochemical analysis and carotid artery ultrasound examination were finished by trained medical staff. According to the hs-CRP 3 mg measurements at the first and third times health examinations,all subjects were divided into four groups,including continued decreasing group(hs-CRP < 3 mg/ L),decreasing group(hs-CRP decreased from≥3 mg/ L to < 3 mg/ L ),increasing group((hs-CRP increased from < 3 mg/ L to≥3 mg/ L)and continued high group((hs-CRP ≥3 mg/ L). Multiple logistic regression analysis was used to test the impact of change of hs-CRP on carotid artery plaque. Results Incidence of carotid artery plaques in continued decreasing, decreasing,increasing and continued high groups were 33. 6%(1 308 / 3 577),44. 7%(178 / 398),45. 1%(186 / 412)and 54. 9%(151 / 275),respectively. The dependent variable was named based on carotid artery plaque(1 = plaque and 0 = no plaque),and in dependent variable was named based on hs-CRP value change (0 = continued decreasing group;1 = decreasing group;2 = increasing group;3 = continued high group). Multiply factors logistic regression analysis showed that the risk of carotid artery plaques for women increased compared to decreasing group( RR = 1. 17,95% CI:1. 01 - 1. 35,P = 0. 035). After adjusting gender,age,smoking,low density lipoprotein cholesterol,fasting blood-glucose,baseline lg( hs-CRP)and body mass index,the risks of developing carotid artery plague in increasing group and continued high group were increased compared to decreasing group among the women and whole population(for all subject:RR = 1. 33,95% CI:1. 04 - 1. 70,P =0. 023;for women subject:RR = 1. 63,95% CI:1. 08 - 2. 46,P = 0. 021). Conclusion Increasing hs-CRP is a risk factors of incidence of carotid artery plaque possibly.

Objective This research aimed to investigate the function mechanism of lung injury after acute pulmonary embolism.Methods 30 healthy New Zealand rabbits were selected and randomly divided into five groups:control group (with venepuncture applied) and model groups including none-saline (NS) control group,exogenos laptin low doses group,medium dose group and high dose group.ELISA was applied to examine the TNF-αand IL-1β in serum.Results TNF-α and IL-1β content in saline group were higher than that in control group,and the results were statistically significant.In medium dose (50 μg/kg) group,TNF-α and IL-1β levels decreased apparently and the results were statistically significant.In low doses (20 μg/kg) group,TNF-α and IL-1β levels decreased,but the results were not statistically significant.In high dose (100 μg/kg) group,TNF-α and IL-1β levels increased on the contrary.Conclusion Suitable dose of leptin will lead the decrease of postoperative levels of TNF-α and IL-1β after acute pulmonary embolism,which thus have protection function to the injured lung.
