Hyperhomocysteinemia is one of the independent risk factors of cerebrovascular diseases. Methylenetetrahydrofolate reductase (MTHFR) C677T gene mutation often results in the increase of plasma homocysteine levels, but the relationship between the genetic polymorphism of MTHFR and cerebrovascular diseases is not significant.

Objective To investigate the effect of Xuesetong Dripping Pills combined with alprostadil intervention on serum brain natriuretic peptide in elderly patients with chronic congestive heart failure.Methods In 74 patients with chronic congestive heart failure, were randomly divided into observation group and control group, 37 cases in each group.Control group received conventional method.The observation group received Xuesetong Dripping Pills combined with alprostadil on the basis of conventional therapy.Compared the efficacy, the heart function level, walking test and level of serum brain natriuretic peptide between two groups after 15 days’ treatment.Results The total efficiency of observation group was 94.59%, which was higher than 75.68% in the control group, the difference was statistically significant(P<0.05).After treatment, the heart function level improvement in the observation group was better than the control group, the difference was statistically significant(P<0.05).After treatment, 6 min walking test in the observation group(316.4 ±20.7) m, was better than the control group(303.5 ±28.1) m, the difference was statistically significant(P<0.05).The level of serum brain natriuretic peptide in the observation group(608.9 ±158.1)ng/L, was lower than that of the control group(792.7 ±179.4) ng/L, the difference was statistically significant ( P <0.05 ) .Conclusion Xuesetong Dripping Pills combined with alprostadil has good curative effect in the treatment of chronic congestive heart failure,can relieve the abnormal increase of serum brain natriuretic peptide, improve blood circulation and heart function.

Objective To observe the cell apoptosis, oxidative stress reaction and expressions of Bcl-2 and Bax in kid?ney of dietary zinc deficiency mice during growth period, and discuss the mechanism of renal cell apoptosis induced by zinc deficiency. Methods Thirty weaning male mice were randomly divided into zinc-deficient group and zinc-adequate group, and 15 mice for each group. Zinc-deficient group was fed with zinc deficiency diet (0.85 mg/kg), while zinc-adequate group was fed with enough zinc diet (30 mg/kg). The TUNEL method was applied to observe the cell apoptosis, and the apoptotic in?dex was measured. The content of SOD and MDA were detected to observe the oxidative stress reaction in kidney. The ex?pression levels of Bcl-2 and Bax protein were detected by Western blot assay. Results Compared with zinc-adequate group, the cell apoptosis and oxidative stress reaction were increased in zinc-deficient group. The expression of Bcl-2 de?creased, and the expression of Bax increased. The ratio of Bcl-2 and Bax declined in kidney of zinc deficiency mice. Conclu?sion Diet zinc deficiency in growth period may result in the decreased antioxidase, the increased oxidative stress reaction, and the changed Bcl-2 and Bax expression, which promote the occurrence of cell apoptosis in kidney.

BACKGROUND: Electrostatic layer-by-layer (LbL) self-assembly is a simple, effective and novel approach to carrying macromolecules into microcapsule carriers.OBJECTIVE: To prepare chitosan (CS) microcapsules to control the releasing of heparin (Hep) by LbL.METHODS: CS microspheres were fabricated by a sodium sulfate-based precipitation process and then used as positively charged templates for polyelectrolyte multilayer coatings to carry heparin by the LbL self-assembly technique. The polycation was CS and the polyanion was Hep. The microcapsule was formed via coating {CS/Hep}3 on CS hydrogel template. The microcapsules composed of {CS/ Hep}3 on CS hydrogel templates were confirmed by fluorescence inverted microscopy, confocal laser scanning microscopy and laser particle size analysis. The assembly of polyelectrolyte layers on CS hydrogel microspheres was monitored by Zeta Potential Analyzer.RESULTS AND CONCLUSION: The resulting microcapsules were about 1 μm in average diameter, and allowed spontaneous loading of heparin through electrostatic interaction, with the encapsulation efficiency and carrying capacity of 83.8% and 3.05%, respectively.

Objective To study the clinical value of detection of peripheral blood natural killer(NK) cells subsets in patients with malignant hematological diseases.Methods A total of 100 patients with malignant blood disease were enrolled from March 2014 to April 2016 as the observation group,including 50 cases in acute stage and 50 cases in mild stage.At the same time,100 health subjects were enrolled as the control group.The number of NK cells in peripheral blood and the changes of subgroups were compared.Results The number of NK cells in the different groups were compared,the absolute numbers and relative numbers of NK cells in the acute phase of leukemia and lymphoma were much lower than those in the control group(P<0.05).While the absolute number and relative number of NK cells in mild stage of leukemia and lymphoma were higher than that in acute phase(P<0.05).After treatment,the absolute number and relative number of NK cells in patients with leukemia and lymphoma were higher than before treatment(P<0.05).Before treatment,levels of CD56bright and CD56dim in patients with leukemia and lymphoma were statistically different with those of control group(P<0.05).After treatment,CD56bright and CD56dim levels were significantly improved in both groups(P<0.05).Conclusion The number of peripheral blood NK cells in patients with hematological malignancies could be reduced,and the cells function might be compromised.Detection of NK cell subsets could be with guiding significance in the treatment of malignant hematologic disease.

Visfatin was recently reported as an adipokine and was found to exert insulin-mimicking effects.The results showed that the expression of visfatin parallelled with obesity and insulin resistance in long term high fat chow-fed rats.The expression of visfatin mRNA was decreased and the insulin resistance improved after rennin-angiotensin system was blocked.Visfatin may play an important role in the pathogenesis of insulin resistance.

Objective:To analyze the therapeutic effect of atorvastatin combined irbesartan on arterial and ventricular remodeling in patients with essential hypertension (EH).Methods:A total of 114 EH patients of our hospital were selected.According to therapeutic protocol,they were divided into irbesartan group (n=72,only received irbesar-tan treatment)and combined treatment (n=42,received atorvastatin combined irbesartan therapy).After three-month treatment,carotid intima-media thickness (IMT),left ventricular end-diastolic diameter (LVEDd),inter-ventricular septal thickness (IVST),left ventricular end-diastolic posterior wall thickness (LVPWTd)and wall mo-tion score index (WMSI)were compared between two groups.Blood pressure and blood lipid levels were compared between two groups.Results:Compared with irbesartan group,there were significant reductions in IMT [(0.98± 0.13)mm vs.(0.81±0.08)mm],LVEDd [(55.2±3.9)mm vs.(43.3±2.8)mm],IVST [(14.9±2.6)mm vs. (11.5±1.8)mm]and WMSI [(1.67±0.22)vs.(1.39±0.16)],P <0.05 all;there were significant reductions in levels of blood pressure [(144±12)/ (94±8)mmHg vs.(136±16)/ (86±8)mmHg],total cholesterol [(5.87 ±0.96)mmol/L vs.(4.53±0.57)mmol/L]and low density lipoprotein cholesterol [(3.46±0.59)mmol/L vs. (2.68±0.42)mmol/L],P <0.05 all,and significant rise in level of high density lipoprotein cholesterol [(0.87± 0.13)mmol/L vs.(1.36±0.24)mmol/L,P <0.05]in combined treatment group.Conclusion:Atorvastatin com-bined irbesartan can significantly improve blood lipid,arterial and ventricular remodeling in EH patients.
