Chinese Pharmacological Bulletin 2003;0(12):-
Aim To investigate the protective effects of omapatrilat on human umbilical vein endothelial cells (HUVECs) injury induced by angiotensin Ⅱ (AngⅡ) in culture. Methods Cultured HUVECs were randomly divided into 4 groups:①control; ②AngⅡ;③omapatrilat and ④AngⅡ+omapatrilat. Lactate dehydrogenase (LDH) leakage was evaluated by spectrophotometer and cell cycle by flow cytometry (FCM); Nitric oxide (NO) was measured by colorimetry and endothelin-1 (ET-1) by radioimmunoassay. Results 10 -7 mol?L -1 AngⅡ significantly increased LDH leakage and ET-1 release, and this increase was inhibited by omapatrilat (10 -6 mol?L -1). Omapatrilat promoted HUVECs proliferation and NO release. Conclusion Omapatrilat can protect human umbilical vein endothelial cells injury induced by angiotensin Ⅱ in culture, suggesting that it may play an important role in prevention and treatment of vascular diseases.

ObjectiveTo study the effect of adding various doses fentanyl to 0.75% bupivacaine for spinal anesthetic in the population undergoing inguinal hernia repair surgery. MethodsThe population of 100 patients belonging to ASA class Ⅰ and Ⅱ ,scheduled for elective inguinal hernia repair, were randomized to receive a spinal anesthetic with 2 ml 0.75% bupivacaine and 1.0 ml saline (group B),or 50 μg/ml fentanyl 0.1,0.2,0.4,0.6 ml(group BF5, group BF10, group BF20,group BF30),each group with 20 cases.Subarachnoid block was established in the left lateral position in L2-3 space by use of a midline approach. The volume of injected drug was kept constant at 3 ml. The time to the highest level of sensory block, the time for regression until T12 level, the time for complete motor recovery, the maintenance duration of the analgesia,the anesthesia effect of the groups, duration of surgery, drug-related side effects were assessed and recorded.ResultsThe time of the highest level of sensory block in group BF30 was shorter than that in group B,group BF5, group BF 1 0, group BF20 (P < 0.05 ), but group B and group BF5 was longer than group BF10,group BF20, group BF30(P < 0.05 ). The time of regression to T12 level in group BF20 was longer than that in group B, group BF5, group BF10, group BF30 (P<0.05),but group B and group BF5 was shorter than group BF10, group BF20, group BF30(P< 0.05 ). The time for complete motor recovery and the maintenance duration of the analgesia in group B and group BF5 was shorter than that in group BFI0,group BF20, group BF30 (P < 0.05 ). The occurrence of pruritus in group B (0) was lower than that in group B F5 (8 cases),group BF10 (3 cases), group BF20 (6 cases), group BF30 (6 cases)(P<0.05). There were no cases of respiratory depression in five groups. ConclusionsIt suggests that in the population receiving spinal anesthetic for hernia repair surgery, addition of 10 μ g fentanyl to 0.75% bupivacaine significantly improves the quality and duration of analgesia. No further advantage occurs if the dose of fentanyl is increased among 30 μg.

Objective To investigate the survival rate and the influencing factors in lupus nephritis (LN) patients with neuropsychiatric systemic lupus erythematosus (NPSLE). Methods Clinical characteristics and biochemical markers of 78 patients including 59 variances were analyzed. Patients were followed up from the onset of NPSLE to death. Patient survival rate was estimated by Kaplan-Meier method. Cox regression model was used to analyze influencing factors. Results Sixteen (20.5%) of 78 patients died of SLE or its complications. Infection was the main cause of death (31.3%). One-, 3-, 5- and 10-year survival rates were 83.2%, 81.7%, 76.7% and 76.7%, respectively. Hypertension (RR =6.965,95% CI:1.578-30.746, P= 0.010), pulmonary infection (RR=8.171,95% CI:1.954-34.177, P=0.004)and acute renal failure (RR=6.978,95%CI:2.063-23.609, P=0.002) were risk factors of mortality, while cyclophosphamide (CTX) impulse therapy (RR =0.130,95 % CI:0.031-0.541, P=0.005) and resolution of NPSLE (RR= 0.169, 95%CI:0.042-0.679,P=O.012)were protective factors. Conclusions Infection is the main cause of death in patients of LN complicated with NPSLE. Survival rate of LN patients with NPSLE in this study is lower than those of LN and NPSLE alone reported by other authors. Hypertension, pulmonary infection and acute renal failure are risk factors of mortality, while CTX impulse therapy and resolution of NPSLE reduce the mortality and improve the prognosis.

Objective To explore the expression of matrix metalloproteinase-3 (MMP-3) and matrix metalloproteinase-10 (MMP-10) in normal endometrium, atypical hyperplasia and endometrial adenocarcinoma. We aimed to study the relationship of MMP-3 and MMP-10 expressions with infiltration depth, histologic grade and clinical phase in order to explore the role of MMP-3 and MMP-10 in the occurrence, infiltration and metastasis of endometrial adenocarcinoma. Methods The expressions of MMP-3 and MMP-10 were measured by immunohistochemistry in 12 cases of normal endometrium, 12 cases of atypical hyperplasia and 42 cases of endometrial adenocarcinoma. Results The expression of MMP-3 was 73.8% (31/42), 25.0% (3/12) and 8.3% (1/12) in endometrial adenocarcinoma, atypical hyperplasia and normal endometrium, respectively, whereas the expression of MMP-10 was 76.2% (32/42), 33.3% (4/12) and 0(0/12), respectively. Both MMP-3 and MMP-10 expressions exhibited a pattern of decreased intensity in endometrial carcinoma, atypical hyperplasia and normal endometrium. Furthermore, the statistical analysis showed that the expression of both proteins was significantly greater in endometrial carcinoma than in atypical hyperplasia and normal tissue (P<0.01). Expressions of MMP-3 and MMP-10 had a significant correlation with such clinical parameters as histologic grade, depth of myometrial infiltration and clinical stage (P<0.01). Conclusion MMP-3 and MMP-10 can be used as tumor markers of endometrial carcinoma, and the combined detection of them can increase the detection rate of endometrial carcinoma.
