Clinical study of fuzheng jiangnian capsule in improving pre-thrombosis correlated factors in patients with coronary heart disease / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the effect of Fuzheng Jiangnian Capsule (FZJN) on the pre-thrombosis correlated factors in patients with coronary heart disease (CHD).</p><p><b>METHODS</b>Ninety patients with CHD complicated with blood hyperviscosity syndrome were treated with conventional treatment and randomly divided into three groups by the additional treatment, i. e. the FZJN group (FZJN, a preparation with action of invigorating Pi, supplementing Shen, and activating blood circulation), the CSDP group [Compound Salviae droplet pill, CSDP) with the action of activating blood circulation to remove blood stasis) and the aspirin (ASP) group, 30 patients in each group. After two months of treatment, clinical efficacy, the levels of endothelin (ET), nitric oxide (NO), coagulation factor I (Fib), D-dimer (DD), thrombocytic granule membranous glucoprotein (CD62p), superoxide dismutase (SOD), high- and low-density lipoprotein-cholesterol (HDL-C, LDL-C) in patients before and after treatment were observed and compared with those in the healthy control group.</p><p><b>RESULTS</b>Compared with the healthy control group, the levels of Fib, DD, ET, CD62p were significantly higher, NO and SOD significantly lower (P<0.05, P<0.01) in all the patients with CHD. Compared with the same group before treatment, the levels of Fib, DD, ET, CD62p, LDL-C in the FZJN group lowered significantly, while NO and SOD raised significantly (P <0.05, P <0.01). ET and CD62p in the CSDP group lowered significantly, while SOD raised significantly (P < 0.05), CD62p in the ASP group lowered significantly (P < 0.05). No statistical difference was found in comparison of DD or ET, though certain improvement was shown. The total effective rate in relieving TCM syndromes and angina pectoris, and the decrease or stop rate of nitrate esters medication were superior in FZJN group to those in the CSDP group and the ASP group, respectively (P <0.05). The rate of electrocardiogram improvement in the FZJN and CSDP group was superior to that in the ASP group (P< 0.05).</p><p><b>CONCLUSION</b>Increase of Fib, DD, ET, CD62p, and decrease of NO and SOD levels were found in patients with CHD in prethrombosis stage. Compared with ASP, compound Chinese medicinal herbs can act on the prethrombosis manner of CHD patients through multi-paths, multi-links. FZJN showed better efficacy in improving correlated blood molecule markers and clinical syndromes than CSDP, suggesting that the possible mechanism of FZJN might be related to its actions in dilating blood vessels, improving microcirculation, alleviating endothelial cell damage, inhibiting activity of blood platelet, regulating coagulation-fibrolysis balance, improving metabolism of free radicals as well as lowering the level of LDL-C.</p>

Study on the relationship between self-rated health situation and health status in the elderly-an 8-year follow-up study from Multidimentional Longitudinal Study of Aging in Beijing / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the relationship between self-rated health (SRH) and prevalence of chronic diseases, and all-cause mortality in the elderly population.</p><p><b>METHODS</b>In 1992, a cohort of 3257 people > or = 55 years old was selected from Beijing, the information of SRH and other related variables were collected from 3 157 subjects at the baseline survey. Three follow-up surveys were conducted in 1994, 1997 and 2000, respectively.</p><p><b>RESULTS</b>The SRH was influenced by age, gender, marriage status and satisfaction on their own economic condition. Comparing the subjects with excellent SRH, the prevalence rates of chronic diseases, stroke, heart diseases and respiratory system diseases were almost doubled among those with average and poor SRH. By 2000, 993 death occurred. All-cause mortality was negatively associated with SRH, i.e. the risk of death was 12% which was 53% higher for the subjects with average SRH (HR = 1.12, 95% CI: 0.93 - 1.35) and poor SRH (HR = 1.53, 95% CI: 1.25 - 1.88) than those with excellent SRH, respectively. The risks of death from stroke and heart disease were 2.25 (HR = 2.25, 95% CI: 1.67 - 3.04) and 2.22 (HR = 2.22, 95% CI: 1.61 - 3.07) times higher among the subjects with poor SRH than those with excellent SRH respectively. After adjustment for age, gender, resident place, marriage status, education, satisfaction on their own economic condition, seeing doctors or hospitalized within the last 1 year, history of chronic disease, cognition function, body mass index, activities of daily living and depression, as well as deleted the subjects died within first or third year of the baseline survey respectively, poor SRH remained a significantly independent predictor to all-cause death as well as to the death of stroke and heart diseases.</p><p><b>CONCLUSIONS</b>The frequency of poor SRH was influenced by age, gender, marriage status and satisfaction on their own economic condition. Poor SRH was associated with the prevalence of chronic conditions and mortality among the elderly. The findings suggested that SRH might have served as an important indicator in the evaluation on health status among the elderly.</p>

Studies on extraction factors of buxueyangyan mixture / 中国中药杂志

<p><b>OBJECTIVE</b>To study the optimum extraction factors of Buxueyangyan Mixture.</p><p><b>METHOD</b>The orthogonal design was used to select the optimum extraction factors of Cervi Pantotrichum etc. and water extraction rate was used to evaluate the factors. The orthogonal desingn was used to study three factors including crude particle size, extraction time and amount of water. Lcariine content was used as analytical parameter.</p><p><b>RESULT</b>The optimum extraction factors for Cervi Pantotrichum etc. were: 3 a volume ofwith 10 times of water used for three extraction 2.5 h each time. The optimum extraction factors for others were: 1 cm or smaller the crude particle size, boiling 2 times: 2.5, 1.5 h respectively the amount of water used was 10. 8 times of the drug mixture respectively.</p><p><b>CONCLUSION</b>According the optimum extraction factors, the active substance can be extracted efficiently.</p>
