Objective To investigate the effect of transforming growth factor β receptor-Ⅱ(TGF-βRⅡ) on AngⅡ inducing glomerular mesangial cell(GMC) proliferation and the expressions of TGF-β1 and psmad3 through transfecting TGF-βRⅡsmall interfering RNA(siRNA)into GMC. Methods Through transfecting fluo-rescence control siRNA into GMC ,we observed the transfection efficiency under fluorescence microscope after 6 hours. Transfecting TGF-βRⅡsiRNA and negative control siRNA into GMC respectively ,we detected the expres-sion of TGF-βRⅡ by western blot after 24 hours. The cells were divided into four groups:control group,AngⅡgroup,negative siRNA control group and TGF-βRⅡ siRNA group. Each group was stimulated by AngⅡ except the control group. After 24 hours,we detected the TGF-β1 and psmad3 protein levels by western blot and detected GMC proliferation by CCK8 kit. Results (1) Comparing with the scrambled control group,the expression of TGFβRⅡin the TGF-βRⅡsiRNA group was significantly decreased(P<0.05).(2)AngⅡcould accelerate the expression of TGF-β1. Transfecting TGF-βRⅡsiRNA into GMC decreased the expression of TGF-β1 protein(P<0.05).(3)AngⅡ could stimulate the phosphorylation of smad3. Transfecting TGF-βRⅡ siRNA into GMC de-creased the expression of psmad3 protein(P < 0.05).(4)Transfecting TGF-βRⅡ siRNA into GMC relieved the GMC proliferation AngⅡ-promoted(P < 0.05). Conclusions The AngⅡ stimulates the GMC proliferation,de-pending on the expression of TGF-βRⅡ. It is related to the expressions of TGF-β1 and psmad3.

Objective To investigate the effect of hosphocreatine therapy on the plasma cardiotrophin-1(CT-1) and N terminal probrain natriuretic (NT-proBNP) in elderly hypertensive patients with heart failure. Methods A total of 76 hy-pertensive patients with heart failure, aged 65 or over, were randomly divided into treatment group and control group (n=38 for each group). The control group received routine anti-heart failure treatment. The treatment group received conventional therapy plus creatine phosphate sodium for 2 weeks. The plasma levels of CT-1 and NT-proBNP were determined in two groups. The plasma CT-1 level was measured by a double antibody sandwich enzyme-linked immunosorbent assay (ELISA). The plasma level of NT-proBNP was tested by Rui Pu fluorescent dry quantitative analyzer. Results The plasma levels of CT-1 and NT-proBNP were significantly lower after treatment in two groups (P＜0.01). The plasma levels of CT-1 and NT-proBNP were significantly decreased in treatment group than those in control group (P＜0.05). The total effective rate was 89.47%in treatment group, which was significantly higher than that of control group (71.05%, P＜0.05). Symptoms of heart failure improved in one week (21 cases in treatment group/9 cases in control group) and in two weeks (13 cases in treatment group/18 cases in control group). Conclusion The conventional therapy plus creatine phosphate sodium can decrease the plasma CT-1 and NT-proBNP levels in elderly hypertensive patients with heart failure, which improves symptoms of heart failure in a shorter period of time.

Objective: To understand the vaccination coverage and associated factors among children under 7 years old in rural areas of Ningxia in 2019, so as to provide a basis for better immunization plans and corresponding strategies in this region. Methods: A multi-stage stratified cluster random sampling method was adopted to select 1 144 children under 7 years old and their families in three rural counties of Ningxia. Demographic information, as well as primary and secondary immunization was investigated. Multivariate Logistic regression analysis was conducted on the relevant factors. Results: In Ningxia, the coverage rate of primary vaccines for children under 7 years of age for hepatitis B vaccine, BCG vaccine and dpt vaccine was above 95%, polio vaccine 83.7%, measles vaccine 38.6%, "five vaccines" 33.8%, and the coverage rate of secondary vaccines was only 4.9%. There were statistically significant differences in the total vaccination rates of "five seedlings" in different ages, per capita annual income of different families, and whether they had received a health examination in the past year (χ2=33.60,13.17,29.96,P<0.05). There were statistically significant differences in the vaccination rates of secondary vaccines among different age groups, different inoculation units and whether received a physical examination in the last year (χ2=18.58, 8.45, 60.04, P<0.05). Multivariate analysis showed that the age of children and whether received physical examination in the last year were the relevant factors affecting the total inoculation of five seedlings(P<0.05). Age of children and inoculation unit were the relevant influencing factors affecting the secondary immunization(P<0.05). Conclusion The primary vaccination rate for children under the age of 7 in rural areas of Ningxia is kept at a high level, but the secondary vaccination rate is relatively low. It is suggested to strengthen publicity and education and establish effective mechanisms to improve the vaccination rate and protect the health of children in rural areas.

Objective:To investigate the effect of microRNA-124 (miR-124) expression on pathological changes of Tau in elderly patients with Alzheimer disease to provide a new target for early detection and early treatment of Alzheimer disease in the elderly.Methods:The serum of 50 patients with Alzheimer disease from June 2017 to June 2018 in the Third People′s Hospital of Qinghai Province Hospital was taken as the sample of the research group and the serum of 50 healthy people was taken as the control sample. The mRNA expression of miR-124 in serum was determined by real-time polymerase chain reaction. The double antibody sandwich enzyme-linked immunosorbent assay was used. The expression levels of Tau protein and phosphorylated Tau (PTau) protein (S396, T181 and T231) were examined; pathological changes of Tau protein were detected by positron emission tomography.Results:The mRNA expression of serum miR-124 in Alzheimer disease patients was significantly higher than that in the control group (6.91 ± 0.41 vs. 5.11 ± 0.37, P < 0.01). The expression levels of total Tau protein, PTau (S396) protein and PTau (T181) protein in Alzheimer disease patients was significantly up-regulated, compared with those of the control group: (195.16 ± 20.48) ng/L vs. (123.25 ± 20.26) ng/L, (69.35 ± 8.92) ng/L vs. (40.53 ± 4.36) ng/L, (66.83 ± 8.45) ng/L vs. (35.87 ± 2.18) ng/L, P < 0.05. The pathological changes of Tau protein were clinically manifested as brain deposition, and the main parts were frontal lobe, occipital lobe, parietal lobe and temporal lobe. The overexpression of miR-124 was positively correlated with high expression of PTau (S396), high expression of PTau (T181) and high expression of total Tau, and it was an independent influencing factor. Conclusions:Overexpression of miR-124 can promote the expression of total Tau protein and phosphorylation of Tau protein, which is clinically indicative of Tau protein deposition in the brain of Alzheimer disease patients. It is expected to be a prognostic biomarker for Alzheimer disease.
