OBJECTIVE:To compare the clinical efficacy and safety of Shexiang baoxin pills and Shensong yangsin capsules in the treatment of coronary heart disease complicated with chronic heart failure and premature ventricular contractions. METHODS:129 patients with chronic heart failure and premature ventricular contractions were randomly divided into blank group(n=43),ob-servation group(n=43)and control group(n=43). All groups received routine treatment as oxygen inhalation,diuretics. Control group additionally received Shensong yangsin capsules 4 pills for 3 times per day. Observation group additionally received Shexiang baoxin pills 2 pills for 3 times per day. Treatment course of 2 groups lasted for 3 months. Clinical efficacies of 2 groups were ob-served,and heart function,cardiovascular autonomic nervous function and vascular endothelial function were observed before and after treatment. RESULTS:Total effective rate of observation group was significantly higher than that of control group(P<0.05). SDNN,SDANN,RMSSD,QTd was no statistical significance between control group and observation group(P>0.05). LVEF, NO of observation group were significantly higher than that of control group(P<0.05),IVST,LVDd,LVPWT,ET of observation group were significantly lower than that of control group(P<0.05). But control group and observation group were better than the blank group,and no obvious adverse reaction. CONCLUSIONS:Shexiang baoxin pills is more effective than Shensong yangsin cap-sules in the treatment of coronary heart disease complicated with chronic heart failure and premature ventricular contractions.

OBJECTIVE:To observe the clinical efficacy and safety of Mailuoning injection in the treatment of acute bronchial asthma. METHODS:92 patients with acute bronchial asthma were randomly divided into control group and observation group. Pa-tients in control groups were received routine treatment,including oxygen inhalation,glucocorticoid,β2 agonists,aminophylline and anti-infection,etc. Patients in observation group were added Mailuoning injection 20 ml adding into 5% glucose injection or 0.9% sodium chloride injection 500 ml by intravenous infusion,once a day,based on the treatment of control group. The course was 14 d. The clinical data was observed,including clinical efficacy,hemorheology indicators,pulmonary function,6-keto-PGF1αlevel and incidence of adverse reactions before and after treatment. RESULTS:The total effective rate in observation group was sig-nificantly higher than control group,with significant difference(P<0.05). After treatment,the hemorheology indicators,lung func-tion indicators and 6-keto-PGF1α level in 2 groups were significantly better than before,and observation group was better than con-trol group,with significant difference(P<0.05). There were no obvious adverse reactions. CONCLUSIONS:Routine treatment combined with Mailuoning injection can effectively improve the efficacy of acute bronchial asthma with good safety.

The relationship between plasma magnesium and plasma lipids was studied in 80 cases of Type II diabetes mellitus. It was found that plasma magnesium in diabetic patients was much lower than that in normal controls. Plasma magnesium was negatively correlated with plasma cholesterol, triglyceride, and LDL-C, and positively correlated with plasma HDL-C, HDL2, and HDL-C/LDL-C, suggesting that hypom-agnesemia was closely related with disturbance in lipid metabolism in diabetes mellitus. Hypomagnesemia seemed to worsen the disturbance of lipid metabolism, and might be one of the factors causing vascular complications in diabetes mellitus

To investigate the relationship between hyperglycemia and hyperlipidemia in diabetics, eighty-six patients with non-insulin dependent diabetes mellitus (NIDDM) were followed up for 6 to 12 months. The results showed that plasma TC, TG, LDL-C levels and LDL-C/HDL-C ratio were elevated in diabetic group as compared with normal control group. Plasma TC and LDL-C levels in the diabetics with mean fasting blood glucose (mFBG) level more than 150 mg/dl were significantly higher than those in diabetics with mFBG less than 150 mg/dl, and those in normal control group as well, but plasma TC, LDL-C and TG levels showed no significant difference between diabetics with mFBG less than 150 mg/ dl and normal controls.The disturbances of lipid metabolism were obviously alleviated following the improvement of diabetic control. These results suggest that better diabetic control can be beneficial to the improvement of lipid metabolic disorders and might be helpful to the prevention of angiopathy in NIDDM patients.

Objective To elucidate the mechanism of inflammation in vascular endothelial cells induced by hypochlorite-modified albumin (HOCl-Alb). Methods HOCl-Alb-induced NADPH oxidase activity in human umbilical vein endothelial cells (HUVEC) was measured by lucigenin-enhanced chemiluminescence. Phosphorylation of p47phox and binding of p47phox and p22phox were measured with immunoprecipitation and Western blotting. Membrane translocation of p47phox was measured with immunofluorescence. RT-PCR and Western blotting were used to determine the intercellular adhesion molecule-1 (ICAM-1) mRNA and protein expression in the presence or absence of apocynin, respectively. Results Co-incubation of HUVEC with HOClAlb resulted in the enhancement of NAIDPH oxidase activity in time- and dose-dependent manner.Compared with bovine serum albumin group, exposure of the cells with 200 mg/L HOCl-Alb for 15min resulted in a 6.16-fold increase in NADPH oxidase activity. Phosphorylation and membrane translocation of p47phox and binding of it with p22phox were also induced by HOCl-Alb. ICAM-1expression was up-regulated after exposure to HOCl-Alb and this effect was significantly abolished by apocynin, a specific inhibiter of NADPH oxidase, in dose-dependent manner. Preincubation of the cells with 500 μmol/L apocynin inhibited the expression of ICAM-1 protein induced by HOClAlb by 68.97% (P＜0.01). Conclusion NADPH oxidase plays a central role in HOCl-Albmediated ICAM-1 expression and provides a mechanism for HOCl-Alb-related vascular endothelial inflammation.

ObjectiveTo understand the status of knowledge,attitude,behaviors about stroke prevention among the high risk population,so as to provide scientific basis for health education. MethodsA selfdesigned questionnaire about knowledge,attitude,behaviors of stroke prevention was used to investigate 106 cases from clinics and communities.The contents included general data,risk of cerebral stroke,score of related knowledge,attitude,behaviors about stroke prevention. ResultsThe mean scores of knowledge,attitude,and behaviors about stroke prevention were(46.96±10.07),(70.71±12.37) and (64.29±16.23),individually.Correlation analysis showed there was significant positive correlation among the scores of knowledge,attitude,and behaviors and their age,educational levels and residence,but was not significantly correlated with sex and risk score of cerebral stroke. ConclusionsPrimary prevention about stroke should focus on the high risk population with lower educational levels,ages under 60 years old,living in suburbs,lack of stroke prevention knowledge.

Cerebral ischemia is one of the diseases of the central nervous system, which is harmful to the morphology and function of brain cells due to reduced cerebral blood flow. Increasingly more reports have demonstrated that spinal cord stimulation could augment the cerebral blood flow, which is expected to be a potential method for the treatment of cerebral ischemia. In this article, the research progress and related problems of spinal cord stimulation for the treatment of cerebral ischemia are reviewed.
