ABSTRACT

Objective:To investigate the efficacy of Bailing capsule combined with conventional western medicine on diabetic nephropathy patientswith maintenance peritoneal dialysis. Methods:Eighty-six type 2 diabetic nephropathy patients receiving peritoneal dialysis in our hospital from February of 2016 to February of 2019 were selected and were divided into control group and observation group according to the random number table method with 43 cases in each group. All patients received continuous ambulatory peritoneal dialysis. Patients in the control group received routine treatment. In the observation group, patients took Bailing capsules based on the treatment of the control group. The two groups were treated continuously for 3 months. Insulin resistance (IR), fasting blood glucose (FPG), fasting insulin (FINS), renal function, and serum levels of microinflammatory factors high sensitivity c-reactive protein (hs-CRP), interleukin (IL)-6, IL-17, and tumor necrosis factor (TNF)-α were compared in the two groups. Results:After the treatment, FPG, FINS, HOMA-IR, blood creatinine, urea nitrogen, and 24 h urinary protein in the observation group were significantly less than those of the control group ( t value were 5.204, 8.227, 14.070, 5.022, 5.900, 5.246, respectively, all Ps<0.01). After thetreatment, serum levels of hs-CRP, IL-6, IL-17, TNF-α in the observation group were significantly lower than those of the control group ( t value were 12.871, 7.021, 7.733, 8.165, respectively, all Ps<0.01). Conclusions:Bailing capsule can effectively improve the insulin resistance and renal function of diabetic nephropathy patients during maintenance peritoneal dialysis and relieve the state of micro-inflammation.

ABSTRACT

To evaluate the relationship between atherosclerosis and hemodynamic of coronary artery in mice detecting by ultrasound bio‐microscopy flow imaging . Methods Double 14 20‐week‐old LDL‐R‐/‐and C57BL/6 male mice were selected ,and randomly divided into two groups in each genotype according to weight . Each two groups were fed to 28 weeks or 36 weeks age respectively with west diet . Coronary artery hemodynamics in these mice were assessed in vivo by Vevo ?2100 ultrasound imaging system ,then the intima‐media thickness( IM T ) of aorta in histopathology were analyzed . T he differences of coronary artery hemodynamic parameters such as maximum velocity ( Vmax ) ,mean velocity ( Vmean) and velocity time integral ( V T I) were compared between mice of different genotypes of the same week and mice of different weeks of the same genotype . And the relationship between coronary artery hemodynamic in ultrasound and aortic IM T in histopathology were analyzed . Results ① All coronary hemodynamic parameters in LDL‐R‐/‐ mice were significantly lower than those of wild‐type mice except the Vmax between two 28‐week‐old genotypes group at the same weeks of age of different genotypes ( all P <0 .05) . But there was no significant difference in coronary artery hemodynamic parameters between mice of the same genotype at different weeks of age( P >0 .05) . ②T he histopathological measurements of aortic IM T in LDL‐R‐/‐mice were significantly higher than those of wild type mice ( all P < 0 .05 ) ,and those of 36‐week‐old mice were significantly higher than those of 28‐week‐old mice ( all P < 0 .05 ) . ③ All coronary hemodynamic parameters such as Vmax ,Vmean and V TI were negatively correlated with pathological measurements of aortic IM T ( r = -0 .532 , -0 .423 , -0 .524 ; all P < 0 .05 ) . Conclusions The parameters of coronary artery hemodynamics obtained by ultrasound bio‐microscopy are well correlated with the pathological results of atherosclerosis . Ultrasound bio‐microscopic flow imaging can be used as a new method to evaluate the degree of atherosclerosis in mice by detecting the hemodynamic parameters of coronary artery .

ABSTRACT

Objective@#To explore the gender-specific risk factors of new-onset cerebral hemorrhage.@*Methods@#In this prospective cohort study,a total of 98 961 participants((51.1±12.6)years old), who underwent the 2006 to 2007 physical examination and met the inclusion criteria, were enrolled from the Kailuanstudy cohort. There were 78 908 (79.7%) male,and 20 053 (20.3%) female.The incidence of cerebral hemorrhage was observed once per year until December 31, 2016.The difference on the incidence of cerebral hemorrhage between male and female was compared. Multivariate Cox regression analysis was applied to analyze therisk factors of cerebral hemorrhage events among different genders.@*Results@#The participants were followed up for(10.00±0.73) years,and 860 cerebral hemorrhage events were recorded during follow up. The incidence of cerebral hemorrhage in the population was 86.90/10 million person years (standardized incidence rate of 47.85/10 million person years). The incidence of cerebral hemorrhage was significantly higher in male (49.61/10 million person years) than in female (34.07/10 million person years, P<0.05). Multivariate Cox regression analysis showed that 45-59 years old, ≥ 60 years old, diabetes,and waist-hip ratio were more strongly related to new-onset of cerebral hemorrhage events in female than in male, and the hazard ratios(95%CI) were 2.33 (1.23-4.43) ,2.71 (1.30-5.66) ,2.16 (1.24-3.74) and 8.79 (1.42-54.32) in female versus 1.55 (1.21-1.97) ,2.16 (1.68-2.78) ,1.19 (0.93-1.53) and 3.21 (1.09-9.41) in male, respectively. The risk of male cerebral hemorrhage increased by 29% (HR=1.29, 95%CI 1.19-1.40) in male and 24% (HR=1.24, 95%CI 1.20-1.28) in female,when the systolic blood pressure increased 10 mmHg (1 mmHg=0.133 kPa).@*Conclusions@#The incidence of cerebral hemorrhage is higher in male than in female in this cohort.The association between systolic blood pressure and cerebral hemorrhage is stronger in male than that in female.The associations between age, waist-hip ratio, diabetes and cerebral hemorrhage are stronger in female than in male.@*Trial Registration@#Chinese Clinical Trail Registry, ChiCTR-TNC-11001489.

ABSTRACT

Objective@#To investigate the impact of blood pressure and age on arterial stiffness in general population.@*Methods@#Participants who took part in 2010, 2012 and 2014 Kailuan health examination were included. Data of brachial ankle pulse wave velocity (baPWV) examination were analyzed. According to the WHO criteria of age, participants were divided into 3 age groups: 18-44 years group (n=11 608), 45-59 years group (n=12 757), above 60 years group (n=5 002). Participants were further divided into hypertension group and non-hypertension group according to the diagnostic criteria for hypertension (2010 Chinese guidelines for the managemengt of hypertension). Multiple linear regression analysis was used to analyze the association between systolic blood pressure (SBP) with baPWV in the total participants and then stratified by age groups. Multivariate logistic regression model was used to analyze the influence of blood pressure on arterial stiffness (baPWV≥1 400 cm/s) of various groups.@*Results@#(1)The baseline characteristics of all participants: 35 350 participants completed 2010, 2012 and 2014 Kailuan examinations and took part in baPWV examination. 2 237 participants without blood pressure measurement values were excluded, 1 569 participants with history of peripheral artery disease were excluded, we also excluded 1 016 participants with history of cardiac-cerebral vascular disease. Data from 29 367 participants were analyzed. The age was (48.0±12.4) years old, 21 305 were males (72.5%). (2) Distribution of baPWV in various age groups: baPWV increased with aging. In non-hypertension population, baPWV in 18-44 years group, 45-59 years group, above 60 years group were as follows: 1 299.3, 1 428.7 and 1 704.6 cm/s, respectively. For hypertension participants, the respective values of baPWV were: 1 498.4, 1 640.7 and 1 921.4 cm/s. BaPWV was significantly higher in hypertension group than non-hypertension group of respective age groups (P<0.05). (3) Multiple linear regression analysis defined risk factors of baPWV: Multivariate linear regression analysis showed that baPWV was positively correlated with SBP(t=39.30, P<0.001), and same results were found in the sub-age groups (t-value was 37.72, 27.30, 9.15, all P<0.001, respectively) after adjustment for other confounding factors, including age, sex, pulse pressure(PP), body mass index (BMI), fasting blood glucose (FBG), total cholesterol (TC), smoking, drinking, physical exercise, antihypertensive medications, lipid-lowering medication. (4) Multivariate logistic regression analysis of baPWV-related factors: After adjustment for other confounding factors, including age, sex, PP, BMI, FBG, TC, smoking, drinking, physical exercise, antihypertensive medication, lipid-lowering medication, multivariate logistic regression analysis showed that risks for increased arterial stiffness in hypertension group were higher than those in non-hypertension group, the OR in participants with hypertension was 2.54 (2.35-2.74) in the total participants, and same results were also found in sub-age groups, the ORs were 3.22(2.86-3.63), 2.48(2.23-2.76), and 1.91(1.42-2.56), respectively, in each sub-age group.@*Conclusion@#SBP is positively related to arterial stiffness in different age groups, and hypertension is a risk factor for increased arterial stiffness in different age groups.

ABSTRACT

Objective: To explore the relationship between longitudinal trajectory of systolic blood pressure (SPB) and atrial fibrillation (AF) in Kailuan group population. Methods: Our study cohort consisted of 40727 participants with the specific criteria in Kailuan group, Tangshan. SAS Proc Traj procedure was used to identify longitudinal trajectories of SPB throughout 2006-2007, 2008-2009 and 2010-2011. There were 5 longitudinal trajectories generated: Low-stable group,n=10950, Moderate-stable group, n=19158, Moderate-high stable group,n=3713, High-moderate stable group,n=4702 and High stable group,n=2181. Log-rank test was performed to compare AF incidence throughout 2012-2013 and 2014-2015 by physical examination among different groups; Multi Cox regression analysis was conducted to study the relationship among different SBP longitudinal trajectories and AF occurrence. Results:①The mean age of participants was (51.81±11.54) years including 30693 (75.4%) male.②AF occurrence rates in Low-stable, Moderate-stable, Moderate-high stable, High-moderate stable and High stable groups were 0.1%, 0.2%, 0.5%, 0.5% and 0.6% respectively, allP<0.05.③Multi Cox regression analysis presented that with adjusted confounding factors, compared with the patients in Low-stable group, Moderate-high stable, High-moderate stable and High stable SBP longitudinal trajectories were the risk factors for new AF occurrence (HR=7.58, 95% CI 2.08-27.73), (HR=5.30, 95% CI 1.88-14.95) and (HR=8.52, 95% CI 1.96-37.09) respectively, allP<0.05. With excluded history of myocardial infarction/stroke, the sensitivity study showed the similar result with the major research trend. Conclusion: Elevated long trajectory of SPB was the risk factor for new AF occurrence in Kailuan group population.

ABSTRACT

Objective To investigate ventricular remodeling and glucose transporter 4(GLUT4) expression in rat with type 2 diabetes mellitus(DM) complicated with myocardial infarction (MI), as well as the effects of ramipril on ventricular remodeling and CLUT4 expression. Method Diabetic animal model (DM) was produced by cholesterol-diet and intraperitoneal injedtion of streptozotocin (STZ,30 mg/kg). The successful model was identified based on the blood gulcose value > 6.7 mmol/L. Left anterior descending coronary artery was ligated to produce the model of MI. 46 wistar rats were randomly(random number) divided into 5 groups: DM + MI + placebo group(placebo group, n = 9), DM + MI + ramipril group(ramipril group, n = 10), DM + sham-operation group (DM group, n = 10),non-DM group + MI (MI group, n = 9), and non-DM + sham-operation group (n = 8). After six weeks, echocardiographic studies was performed ; Left ventricular mass index (LVMI), myocardial infarct size and myocardial collagen volume fraction(CVF) of non-infarction area were also detected. GLUT4 mRNA in the myocardium away from infarction region was measured with real-time fluorescent quantitative RT-PCR and the expression of GLUT4 protein was measured with western blot. Analysis of variance was used to compare the groups. P -values< 0.05 were considered to indicate statistically significant differences. Results Compared with Ml group and DM group,EF[(32 ±3)% vs. (65 ±4)%, P <0.01 and (32 ±3)% vs. (38 ±4)%, P <0.05 respectively] significantly decreased,while E/A ratio (P < 0.01), LVMI (P < 0.05) and CVF (P < 0.05) obviously increased in placebo group. The expression of GLUT4 mRNA and protein were similar between placebo group and DM group, however, much lower than those in MI group(P<0.01).In rampiril group, E/A ratio (P < 0.01), LVMI(3.1±0.2 vs.4.2±0.4, P <0.01) and CVF(P < 0.05) significantly decreased compared with placebo group, while EF[(45±3)% vs.(32±3)%, P <0.01] and the expression of GLUT4 mRNA and protein (P < 0.05) increased. Conclusions Rampiril could improve left ventricular hypertrophy and systolic/di-astolic dysfunction, increase the expression of GLUT4 mRNA and protein in diabetic rats complicated with MI.

ABSTRACT

Objective The purpose of this study was to evaluate the effects and mechanism of ACEI(Fosinopril),AT1 receptor antagonism (Irbesartan),and combination of these two drugs on ventricular remodeling in rats with myocardial infarction.Methods Rats were randomly divided into four groups at twenty-four hours after MI,and treated for 6 weeks.Mean blood pressure and left ventricular end diastolic pressure(LVEDP) were evaluated,as well as ventricular weight(VW)/body weight(BW) ratio.The total,type I and type Ⅲcollagen and nonmyocyte cellular proliferation were quantified by histomorphometry.The expression of transforming growth factor-beta 1(TGF-? 1)mRNA within the noninfarction zone was determined by in situ hybridization.Results Irbesartan and combination therapy decreased total collagen more significantly compared with fosinopril.Combination therapy decreased typeⅠcollagen more significantly than fosinopril.Nonmyocyte cellar proliferation in MI-combination group was more significantly suppressed than in MI-fosinopril group.Treatment with irbesartan or combination therapy normalized TGF-? 1 mRNA level within the noninfarction zone.Conclusion Fosinopril or irbesartan alone ,and combination of these two drugs can limit myocardial hypertrophy,attenuate the development of myocardial interstitial fibrosis,and prevent nonmyocyte cellar proliferation in the noninfarcted left ventricle.The use of irbesartan,especially combined with fosinopril was more effective than fosinopril alone in the suppression of histopathologic changes resulting in ventricular remodeling after MI.Irbesartan and combination therapy was more effective than fosinopril alone in suppressing TGF-? 1 mRNA expression.
