OBJECTIVE: To study the effect of allopurinol on the function of blood vessel endothelium in patients with essential hypertension complicating hyperuricemia. METHODS: 65 cases with essential hypertension complicating hyper uricemia were randomized into treatment and control group. The control group was given the classic non- pharmacotherapy: reduced intake of sodium, more exercise, weight loss etc. The treatment group was treated wilh 100mg allopurinol b.i .d for 4 weeks besides the classical non - pharmacotherapy as stated for the control group. Serum uric acid level, brachial artery flow -mediated diastolic (FMD) function, the base internal diameter of brachial artery, nitrogen oxide (NO), von Willebrand' s factor(vWF) were compared between two groups before and after treatment. RESULTS: As compared with prior treatment, the treatment group had decreased level of uric acid and decreased vWF level, increased level of NO and a significantly increased level of FMD, all had statistical significances(P0.05) . CONCLUSION: Allopurinol can ameliorate the function of blood vessel endothelium in patients with essential hypertension complicating hyperuricemia.

Both carvedilol and metoprolol exhibited no effect on eNOS activity in all the investigated cardiac myocytes. CONCLUSIONS: Nebivolol does no effect on eNOS activity of left ventricular cadiocytes in subjects or rats without hear failure but it can inhibit eNOS activity of cadiocytes in subjects or rats with heart failure so as to exert its beneficial clinical effect.

OBJECTIVE:To study the efficacy of Urokinase vs.Low Molecular Weight Heparin in the treatment of acute pulmonary thromboembolism.METHODS:A total of 35 patients with acute pulmonary thromboembolism who had no past history of heart and lung diseases were enrolled and randomly assigned to two groups following ultrasonography and pulmonary ventilation/perfusion scanning:15 were given thrombolysis therapy with urokinase,and 20 given anticoagulation therapy with low molecular weight heparin.Symptoms,arterial blood gas analysis,electrocardiogram,echocardiogram were compared in two groups before and after treatment.RESULTS:The patients receiving thrombolysis therapy had better improvement in symptoms,arterial blood gas index,echocardiogram and the pulmonary ventilation/perfusion scanning than in those receiving anticoagulation therapy(P

Objective To investigate correlation of right ventricular hypertrophy and vitamin D , atrial fibrillation and NT-proBNP in patients with pulmonary heart disease.Methods 40 cases of pulmonary heart disease were selected, according to whether the right ventricular hypertrophy or not, and divided into hypertrophy group and non hypertrophy group.Echocardiography, serum 25 hydroxy vitamin D, 24 h dynamic electrocardiogram and NT-proBNP level were detected, and the correlation were detected between the right ventricular hypertrophy and influence factors.ResuIts The right ventricular anterior wall ( RVAW) and right ventricular diastolic diameter ( RVDd) in hypertrophy group were significantly greater than those in non hypertrophy group (P<0.05).The serum 25 hydroxy vitamin D levels in hypertrophy group was lower than that in non hypertrophy group (P<0.05), but there was no significant correlation of right ventricular hypertrophy and 25 hydroxy vitamin D levels(r=-0.189,P=0.424).The thickness of right ventricular anterior wall in atrial fibrillation group was greater than that in non atrial fibrillation group (P<0.05), but there was no significant correlation of right ventricular hypertrophy and atrial fibrillation times(r=0.178,P=0.452).Serum NT-proBNP levels in hypertrophy group was higher than that in non hypertrophy group (P<0.05), but there was no significant correlation of right ventricular hypertrophy and serum NT-proBNP levels(r=-0.105, P=0.660).ConcIusion Patients with right ventricular hypertrophy of pulmonary heart disease who has a lower serum 25 hydroxy vitamin D level and a higher NT-proBNP level.Patients with atrial fibrillation has a thicker RVAW.However, there was no correlation of above influence factors.

Objective This research aimed to investigate the function mechanism of lung injury after acute pulmonary embolism.Methods 30 healthy New Zealand rabbits were selected and randomly divided into five groups:control group (with venepuncture applied) and model groups including none-saline (NS) control group,exogenos laptin low doses group,medium dose group and high dose group.ELISA was applied to examine the TNF-αand IL-1β in serum.Results TNF-α and IL-1β content in saline group were higher than that in control group,and the results were statistically significant.In medium dose (50 μg/kg) group,TNF-α and IL-1β levels decreased apparently and the results were statistically significant.In low doses (20 μg/kg) group,TNF-α and IL-1β levels decreased,but the results were not statistically significant.In high dose (100 μg/kg) group,TNF-α and IL-1β levels increased on the contrary.Conclusion Suitable dose of leptin will lead the decrease of postoperative levels of TNF-α and IL-1β after acute pulmonary embolism,which thus have protection function to the injured lung.

Objective:To study the efficacy of different systemic chemotherapy regimens as first-line and second-line therapy and to determine the prognostic factors for patients with advanced biliary tract cancer.Methods:The clinical data of patients with advanced biliary tract cancer who underwent systemic chemotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from January 2011 to December 2018 were studied. The efficacy of chemotherapy on objective response rate (ORR) and disease control rate (DCR) were evaluated. Potential prognostic factors for survival were studied using the Cox proportional hazards models.Results:Of 151 patients enrolled into this study, there were 75 males and 76 females, with ages ranging from 31 to 77 years (median 58 years). Two treatment protocols were used: (1) 104 patients received a gemcitabine-based regimen (combined with platinums or fluorouracils) or a combination of platinums and fluorouracils, while (2) 47 patients received a combination of albumin-bound paclitaxel and S-1. The corresponding ORR for each group were 15.4%(16/104) and 27.6%(13/47), respectively, and the DCR were 65.4%(68/104) and 72.3%(34/47), respectively. Of 58 evaluable patients who received chemotherapy as a second-line therapy, 31 patients received the regimen containing gemcitabine, platinums or fluorouracils with an ORR of 3.2% (1/31) and a DCR of 35.5%(11/31); a total of 18 patients received the taxanes-based regimen with an ORR of 11.1%(2/18) and a DCR of 38.9%(7/18); 9 patients received the irinotecan-based regimen with an ORR of 22.2%(2/9) and a DCR of 44.4%(4/9). Univariate analysis showed positive liver metastasis and elevated carbohydrate antigen (CA)19-9 level to be significantly correlated with worse survival outcomes ( HR=1.540, 95% CI: 1.019-2.328, P=0.040 and HR=1.892, 95% CI: 1.123-3.188, P=0.017). Conclusion:For patients with advanced biliary tract cancer, in addition to the conventional regimens containing gemcitabine, platinums and fluorouracils, the combination of albumin-bound paclitaxel and S-1 was shown to be an effective chemotherapeutic regimen for these patients. Second-line chemotherapy was insufficient and ineffective, and an irinotecan-based regimen deserves to be further investigated. Liver metastasis and elevated CA19-9 level were worse prognosis after chemotherapy for patients with advanced biliary tract cancer.
