BACKGROUND: Early clinical researches suggest that mediodespidine capsule can decrease blood pressure of patients with primary hypertension on the basis of yanggan qinggan pinggan technique.OBJECTIVE: To observe the effect of mediodespidine capsule on primary hypertension and angiotensin Ⅱ (Ang- Ⅱ ) of patients in the types of yin deficiency, yang excess and liver fire.DESIGN: Randomized controlled case observation.SETTING: Department of Cardiology, First Affiliated Hospital, Hunan University of Traditional Chinese Medicine.PARTICIPANTS: Patients were selected from the Inpatient Department and Out-patients Clinic of the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine between April 1999 and April 2000. Inclusion criteria: Patients, who were diagnosed with the criteria of primary hypertension, who belonged to the types of yin deficiency, yang excess and liver fire, who could endure this test, who were coincidence with the criteria of mental-stress test, were all consent. Exclusion criteria: Patients who had severe congestive heart failure, atrophic arthritis and unable tolerance were excluded. There were 60 cases in total, including 29 males and 31females. All patients were divided into mediodespidine group and verapamil group with 30 in each group on the basis of randomly digital table.METHODS: Patients who had positive results of awaken mental-stress test were involved in this study. Cases in mediodespidine group were treated with mediodespidine capsule, which was made of tall gastrodia tuber, spine date seed and fourstamen stephania root at the dosage of 0.43 g/pill and were provided by the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine (wei yao ji zi: 05-047, batch number: 990503), five pills each for 3 times a day. Cases in verapamil group were treatedwith verapamil (40 mg/pill, Shanghai Huanghe Liya PharmaceuticalCompany Limited,batch number: 980301B) 80 mg each for 3 times a day. The course in both groups was 4 weeks. ① Effect of blood pressure: Average value of blood pressure tested for 3 successive days were regarded as the blood pressure before treatment, and average value of blood pressure tested for 3 times after treatment was regarded as the blood pressure after treatment. ② Effect of symptom:Scores were recorded as four levels according to main symptoms, such as vertigo, headache, pain and weakness of waist and knees, before and after treatment. ③ Values of Ang- Ⅱ were measured with radioimmunoassay before and after cold pressor test. Effect on Ang- Ⅱ was evaluated with effect of decompression, effect of clinical symptom and criteria of clinical effect.MAIN OUTCOME MEARUSES: Clinical symptoms, values of blood pressure, heart rate and Ang- Ⅱ before and after cold pressor test.RESULTS: A total of 60 patients with primary hypertension were involved into the final analysis.① Totally effective rate of clinical symptoms of patients in mediodespidine group was higher than that of patients in verapamil group, but the effect of decompression was not significant between the two groups (P ＞ 0.05). ② There was remarkably significant difference of heart rate in both groups before and after treatment (P ＜ 0.01), especially the decrease in verapamil group was great, and there was significant difference (P ＜ 0.05). ③ Values of systolic pressure and diastolic pressure were decreased in both groups after cold pressor test (P ＜ 0.01), but there was no significant difference between the two groups (P ＞ 0.05). ④ There was no significant difference in clinical effect between the twogroups (P ＞ 0.05).⑤ After treatment, concentration of Ang- Ⅱ at basic level in both groups was decreased, and there was significant difference between them (P ＜ 0.01);concentration of Aug-Ⅱ was decreased in both groups after cold pressor test as compared with that before treatment, but there was no significant difference between them (P ＞ 0.05).CONCLUSION: Mediodespidine capsule can decrease blood pressure stably, and the effect is stronger than that of verapamil at the aspect of decompression and improving symptoms. Blood pressure of patients with primary hypertension in the types of yin deficiency and yang excess or liver fire can be decreased by decreasing the level of plasma Ang-Ⅱ to a certain degree.

Objective To determine the biological traits and optimal condition for the induction and differentiation of endothelial progenitor cells from peripheral blood in healthy adults. Methods Mononuelear cells were isolated from peripheral blood of healthy adults by Ficoll-density eentrifugation. The isolated ceils were cultured in 1640 medium supplemented with VECF165 and bFGF. The EPC specific surface mark CD34 and KDR were assessed by fluorescence activated cell sorter(FACS)analysis: EPC were characterized as adherent cells double positive for DiL-acLDL uptake and lectin binding by direct fluorescent staining under a hser scanning confocal microscope. EPC migration were assayed by MTr assay. Result The number and migration ability of EPC were increased by VEGFl65 and bFGF. Conclusion Endothelial progenitors cells can be derived from mononuclear cells of peripheral blood at specific conditions.

OBJECTIVE To study the therapeutic effect and the underlying mechanism of asiatico?side on bleomycin-induced rat interstitial pulmonary fibrosis(IPF). METHODS Male Sprague-Dawley (SD)rats were divided into normal control group,bleomycin 5 mg·kg-1 model group and asiaticoside 50 mg · kg-1 group. The model and asiaticoside group were administrated with bleomycin 5 mg · kg-1 to induce IPF,while the asiaticoside group was administrated with asiaticoside 50 mg·kg-1 by gastric perfusion. Hematein eosin(HE)and Masson staining were carried out to analyze the histopathological changes in the lung. Lung homogenates were used to examine hydroxyproline(HYP) content,and serum samples were used to measure the concentration of interferon-γ(IFN-γ),interleukin-4(IL-4) and tumor necrosis factor-α(TNF-α). In addition,immunohistochemical methods were used to locate lung transforming growth factor-β1(TGF-β1)and adenosine 2A receptor(A2AR)expression,and Western blotting was used to examine the expression levels of TGF-β1 and A2AR. RESULTS On the 7th,14th and 28th days,the scores of pulmonary inflammation were higher in model group than in control group (P<0.01),and the asiaticoside group showed mitigated alveolitis(P<0.01,P<0.05) compared with model group. Compared with control group,the scores of pulmonary fibrosis in model group were elevated(P<0.01),and the asiaticoside group showed reduced pulmonary fibrosis(P<0.05). On the 14th and 28th days,HYP content in the model group〔1.85±0.10,(2.48±0.18)mg·g-1〕was higher than in the control group〔0.79 ± 0.07,(0.84 ± 0.08)mg · g-1〕(P<0.01),but HYP content in the asiaticoside group〔1.32±0.131,(1.71±0.13)mg·g-1〕was lower than in the model group(P<0.05). IL-4 and TNF-αin the asiaticoside group were lower than in model group(P<0.05),but were higher in the model group than in the control group(P<0.01,P<0.05). The expression level of TGF-β1 protein in the asiaticoside group was lower than in the model group(P<0.05),but was higher in the model group than in the control group(P<0.05). The expression level of A2AR protein in the asiaticoside group was higher than in the model group(P<0.05),but was lower in the model group than in the control group(P<0.05). CONCLUSION Asiaticoside can mitigate bleomycin-induced IPF by inhibiting the expression of IL-4, TNF-αand TGF-β1,and raising the level of A2AR.

Objective To observe the effects of aerobic exercise on low-and high-density lipoprotein cholesterol,and to investigate the relationship between exercise intensities and high-density lipoprotein cholesterol (HDL-C) changes.Methods Sixty patients with low HDL-C were randomly allocated into a high intensity exercise group,a moderate intensity group or a low intensity group with 20 in each group.According to each patient's maximal heart rate in a restrictive electrocardiogram exercise test,the different aerobic exercise intensities were formulated as follows.The target heart rate of the high-intensity training group was 90％ of each subject's maximum heart rate; in the moderate-intensity group it was 70％ ; in the low-intensity group it was 50％.All 3 groups jogged on a medical treadmill for 20 minutes every other day with their heart rates monitored at all times.They maintained the target heart rate for 20 minutes.The experiment lasted 2 months.Results In the high intensity group HDL-C increased from 0.81 ± 0.22 to 1.04 ± 0.33 mmol/L after training; in the moderate intensity group it increased from 0.82±0.20 to 1.03 ±0.37 mmol/L; in the low intensity group it increased from 0.79 ±0.25 to 0.82 ± 0.27 mmol/L.That increase in the low intensity group was not statistically significant.After high intensity or moderate intensity training the HDL-C increases were statistically significant,but the difference between the groups was not.After training,in 15 cases among the high intensity group,13 cases from moderate intensity group and in 1 case from the low intensity group the HDL-C level achieved a normal value (≥ 1.04 mmol/L).Comparing the high intensity group to the low intensity group or the moderate intensity group to the low intensity group,there were significant differences in the number of patients who achieved normal HDL-C readings,but there was no significant difference between high intensity group and the moderate intensity group.Conclusion Low intensity aerobic exercise has no obvious effect on low HDL-C levels.High or moderate intensity aerobic exercise can effectively raise the HDL-C level,but there is no significant difference in the fraction of patients reaching normal values between high and moderate intensity aerobic exercise.So moderate intensity is recommended for improving low levels of HDL cholesterol.
