Objective To observe the influence degree of amlodipine on the blood vessel function and RAAS in patients with hypertension.Methods 80 patients with hypertension were collected as the study objects,all the patients were divided into the control group(enalapril group)of 40 cases and observation group(enalapril combined with amlodipine group)of 40 cases according to the principle of random distribution.Then the blood vessel function indexes and RAAS indexes of the two groups before and after the treatment were respectively detected and compared. Results Before the treatment,blood vessel function indexes and RAAS indexes of observation group and control group did not have significant differences.After treatment,blood vessel function indexes and RAAS indexes of the observation group[the eighth week:sVCAM-1(76.56 ±7.65)μg/L,vWF(66.75 ±7.84)%,ET-1(65.20 ± 6.46)ng/L,VEGF(43.39 ±5.20)ng/L,Ang-Ⅱ(90.51 ±9.46)ng/L,ALD(98.97 ±10.25)ng/L]were signifi-cantly lower than those of the control group[sVCAM-1(90.46 ±9.24)μg/L,vWF(80.41 ±9.21)%,ET -1 (75.35 ±7.46)ng/L,VEGF (54.18 ±5.57)ng/L,Ang-Ⅱ(107.84 ±11.46)ng/L,ALD (131.53 ±11.84)ng/L], there were significant differences between the two groups(all P<0.05 ).Conclusion The influence of amlodipine for the blood vessel function and RAAS of patients with hypertension are great,and it is helpful for the improvement of patients disease state.

OBJECTIVE: To investigate the function of activator protein-1 (AP-1) in proliferation and collagen synthesis of cardiac fibroblasts (CFs) in neonatal rats induced by tumor necrosis factor-alpha (TNF-alpha), and to explore the mechanism of Qiangxin Decoction (QXD), a compound traditional Chinese herbal medicine, in reversing cardiac fibrosis. METHODS: CFs derived from neonatal rats were cultured with enzymatic dissociation, and fibrosis of the CFs was induced by TNF-alpha. The CFs were divided into normal control group, untreated group, 5% QXD-containing serum group, 10% QXD-containing serum group and 20% QXD-containing serum group. After 24-hour culture of QXD-containing serum, AP-1 mRNA was detected by real-time fluorescent quantitative polymerase chain reaction; proliferation and collagen synthesis of CFs were assayed by thiazolyl blue assay (MTT) and measured by hydroxyproline respectively, in order to determine the effect of different dosage decoction on the proliferation and collagen synthesis of CFs. RESULTS: After 24-hour stimulation of TNF-alpha in CFs, compared with those in normal control group, the expression of AP-1 mRNA and cardiac fibroblast proliferation and collagen synthesis increased significantly (P<0.05). However, Qiangxin Decoction could reduce the expression of AP-1 mRNA and decreased the proliferation and collagen synthesis of CFs significantly (P<0.05). CONCLUSION: Qiangxin Decoction can inhibit proliferation and collagen synthesis of CFs induced by TNF-alpha, and reverse cardiac fibrosis, which may be related to its down-regulation of the expression of AP-1.

With worldwide improvements in the regulations of international and domestic clinical trial conductions, the quality of clinical trials and trial data management are receiving a great deal of attention. To ensure the quality of clinical trials, maintain business flexibilities and effectively utilize internal and external resources, the outsourcing model is used in the management of clinical data in operation of pharmaceutical companies. The essential criteria of a successful outsourcing mode in clinical trial are selection of qualified contract research organizations (CRO); establishment of appropriate outsourcing model, and generation of effective quality control systems to ensure the authenticity, integrity and accuracy of the clinical trial data.

Oxidative stress has been demonstrated to be one of the important mechanisms for brain injury. Free radicals are one of the most important products following cerebral ischemia/reperfusion and intracerebral hemorrhage. They are the important markers for evaluating the 2 types of stroke injuries. At present, some relevant biomarkers of oxidative stress, such as lipid, DNA, protein peroxidation, antioxidant enzymes, and non-enzymatic antioxidant molecules as well as inflammatory and anti-inflammatory factors, are increasingly receiving attention. This article reviews and evaluates the biomarkers of oxidative stress in stroke.

Objective To evaluate the clinical efficacy of atorvastatin combined with salvianolate in treatment of chronic obstructive pulmonary disease (COPD) complicated with pulmonary arterial hypertension (PH) , and its influence on hypoxia inducible factor-1 alpha (HIF-1α), endothelin-1 (ET-1), adrenomedullin (ADM) in serum.Methods 30 cases of COPD patients with PH were randomly divided into 2 groups, each of 15 cases.The two groups were given conventional treatment, including rest, continuous low flow oxygen, anti infection, relieving cough and phlegm, relaxing tracheal, correcting water and electrolyte balance.Control group was received Atorvastatin Calcium Tablets 20 mg orally, once daily.Observation group was received Atorvastatin Calcium Tablets 20 mg once daily, once daily;salvianolic 200 mg+0.9% sodium chloride solution 250 mL, intravenous drip, once daily.The course of treatment was 10 d.Before and after treatment, 6 min walking distance(6 MWD) and hemodynamic parameters were detected, including pulmonary artery systolic blood pressure (PASP), cardiac output (CO), right ventricular end diastolic pressure (RVEDP) , and HIF-1, ET-1 and ADM level in serum.Results After treatment, 6MWD, PASP, CO, RVEDP of the two groups were significantly improved compared with the same group before treatment.But compared with control group, observation group was improved significantly, the difference was statistically significant (P<0.05).After treatment, HIF-1 alpha, ET-1 of the two groups were significantly lower than the same group before treatment, but ADM were significantly increaser( P <0.05 ) .Compared with control group, HIF-1 alpha, ET-1 of observation group were significantly decreased, while the ADM was significantly increased, the difference was statistically significant (P<0.05).Conclusion Atorvastatin combined with salvia miltiorrhiza polyphenols can significantly reduce the pulmonary artery pressure in patients with COPD and PH, increase exercise tolerance, and its mechanism maybe related to the regulation of the expressions of HIF-1, ET-1 and ADM.
