缬沙坦/氨氯地平和依贝沙坦/双氢克尿噻联合治疗老龄高血压疗效的研究

Objective To compare the clinical effect of valsartan/amlodipine combination or irbesartan/hydrochlorothiazide(HCTZ)combination in very elderly hypertensives.Methods After a 4-week placebo period,94 hypertensives,aged 75-89 years were random given valsartan 160 mg/amlodipine 5 mg or irbesartan 300 mg/HCTZ 12.5 mg for 24 weeks according to a rospective study.After 4 weeks,amlodipine or HCTZ was doubled in non-responders.Patients were checked every 4 weeks.At each visit,sitting,lying and standing blood pressure(BP),systolic BP(SBP)and diastolic BP(DBP)were measured. At the end of placebo period and treatment period,electrolytes and uric acid were evaluated.Results Blood pressure was significantly decreased in both treatment groups,however,there was no statistical significance between two groups.BP changes from lying to standing position were significantly greater in the irbosartan/HCTZ group(-17.2/-9.1 mmHg)than that in the valsartan/amlodipine group(-10.1/-1.9 mmHg,t=2.14,P＜0.05 for SBP and t=3.11,P＜0.01 for DBP vs.irbesartan/HCTZ).Potassium significantly decreased and uric acid significantly increased(-0.4 mmol/L,t = 2.33,P＜ 0.05 and+29.7μ mol/L,t =2.54,P＜0.05 vs.baseline,respectively)only in the irbesartan/HCTZ group.Conclusions Both combinations had similarly effective in reducing clinical BP in very elderly hypertensives.However,valsartan/amlodipine offered some advantage and less pronounced BP orthostatic changes and absence of metabolic adverse effects.

硝酸甘油对大鼠重症急性胰腺炎ET/NO、TXA2/PGI2的影响

Objective To explore the effect of nitroglycerin on ET/NO, TXA2/PGI2 and pancreas pathomorphology changes in severe acute pancreatitis (SAP) rats. Methods Sixty SD rats were random divided into five groups, including control group (A group, n = 12) and experimental group(B,C,D and E group, n = 12). The SAP was induced by injection of 5% sodium taurocholate through retrograde common biliopancreatic ducts via duodenal papilla with epidural catheter. Group C, D and E were intravenously injected with nitroglycerin 0.5μg/kg/min,1μg/kg/min and 2μg/min in 30 min respectively, and group A and B was injected with Sodium Chloride 0.5ml. The indexes of changed pathomorphology and ET/NO, TXB2/6-keto-PGF1a, were determined at the 6th and 12th hour after operations, respectively. Results The specimen data of the 6th and 12th hour displayed that the indexes of changed pathomorphology, ET, ET/NO, TXB2, and TXB2/6-keto-PGF1a of the group C,D and E degraded respectively, compared to group B(P < 0.05). Conclusion The nitroglycerin could degrade ET, ET/NO,TXA2 and TXA2/PGI2, improve the microcirculation of pancreas, and delay the pathological inflammation change in SAP rats.

利尿剂在三聚氰胺及三聚氰酸致大鼠急性肾损伤中的治疗作用

Objective To investigate the effect of diuretic (furosemide) therapy on kidney injury induced by melamine and cyanuric acid in rats. Methods 36 male Spragne Dawley rats were random disided into 3 groups. Group A was treated with 2mL of water daily, group B was treated with melamine and cyanuric acid ( each 100 mg/kg) daily for 4 days and then 2ml of water daily, group C was treated with the same as group B at the first 4 days and then treatment with furosemide (20mg/kg) daily. Samples of blood and 24h urine were collected to detective biochemical indexes, and kidney sections were performed on days 4 and 11 ( each end point, n = 6). The kidneys were observed with histopathology and renal crystal deposition scores were determined. Results On the 4th day, group B and group C were resulted in acute kidney injury such as oliguria [ ( 3. 39 ± 1.02 ) ml, ( 3. 20 ± 0. 86 ) ml ] and high serum creatinine [ ( 153.54 ±27. 08)μmol/L, (160. 11 ± 19. 55)μmol/L] and renal melamine cyanurate crystal were found in the renal tissues. On the 11th day, the renal crystal deposition score in the rats was reduced by 9. 52% ( P >0. 05). Compared with those of the 4th day in group B, it reduced by 63.63%( P <0.05) in group C. Urine volume were increased significantly compared with those of the 4th day( P < 0. 05 ) in group C [ from (3.20±0. 86)ml to (25.96 ±5.97)ml] and group B [ from(3. 39 ± 1.02)ml to (8. 57 ± 1.66)ml] , and Urine volume in group C was increased significantly more than that in group B ( P < 0. 05 ). The serum creatinine was obviously reduced as compared with those of the 4th day in group B and C( P <0.05), from[ (153. 54±27.08) μmol/L] to [ ( 106. 10 ±5.53) μmol/L] in group B and from [ ( 160. 11 ± 19. 55) μmol/L] to [ (67. 17 ± 12. 80 ) μmol/L] in group C, but the serum creatinine in group B was still higher than that in group A and C ( P < 0. 05). Conclusions Furosemide can attenuate the damage of acute kidney injury induced by melamine and cyanuric acid.

强直性脊柱炎合并骨质疏松的临床研究

Objective To investigate the incidence of osteoporosis (OP) in patients with ankylosing spondylitis and the relationship between OP and the clinical data. Methods Serum levels of bone alkaline phosphatase (BALP) and tartrate resistant acid phosphatase 5b (TRACP5b) were detected by enzyme linked immunosorbent assay ( ELISA ) in 60 cases with ankylosing spondylitis, and it was compared with normal controls. Bone mineral density (BMD) was measured through dual-energy X-ray absorptiometry ( DXA), including lumbar ( L2 - L4), bilateral femoral neck and greater trochanter. Some clinical data was collected and analyzed at the same time. Results The incidence of OP in AS patients was 35%, and the incidence of OP in the femoral proximal end was higher than that in lumbar. Compared with normal controls[ ( 1.06 ±0. 18 )U/L ], the levels of serum TRACP5b in AS[ (1.31 ± 0. 82 )U/L] patients was significantly higher ( P <0. 05 ). The levels of serum BLAP in OP combined AS group[ ( 21.65 ± 5.41 ) U/L]were significantly lower than non-OP group[ (32. 37 ± 16. 5 ) U/L] ( P <0. 05 ). The disease duration was negatively correlated with the BMD of femoral neck ( P < 0. 01 ). Conclusions There was higher incidence of OP in AS patients, which were related with the abnormality of bone metabolism and the disease duration.Multiple factors participated in the regulation of bone metabolism of AS.
