Objective:To study the effect of Liuwei Dihuang decoction (LW) on secretion of testosterone in the testis leydig cells of senescence accelerated mouse (SAM). Methods:The level of testosterone in the testis leydig cells of SAM with aging and the effect of LW on the secretion of testosterone were observed using cultured testis leydig cells in vitro.Results:The level of testosterone in the testis leydig cells of SAMP8 with aging was significantly decreased and showed a significant difference compared with age-matched SAMR1. Chronic administration of LW (2.5 and 5.0 g/kg) for 5 months significantly ameliorated the secretion of testosterone in SAMP8 compared with control group. Conclusions:The secretory function of testis leydig cells was reduced in SAMP8 with aging. LW ameliorated the secretion of testosterone in the testis leydig cells,indicating that LW could antagonize or delay the deterioration of the testis leydig cells in SAMP8.

Method Platelet aggregation test(PAGT), prothrombin time (PT), activated partial thromboplastin time(APTT), tissue factor pathway inhibitor(TFPI), D-dimer and tissue plasminogen activator(t-PA: a)were detected in 48 GC patients(GC group) at two weeks pre- and post-operation respectively;and compared with non-tumor patients(control group). Results Compared with control group, in GC group,especially in GC patients with lymphatic metastasis,the PAGT increased (P

Beta-Elemene is an antitumor drug which is isolated from the traditional Chinese medicinal herb Curcumae Phaeocaulis Rhizoma, it is the main component of elemene which is extracted from the plant and delivered via blood circulation after intravenous injection. The antitumor effect of beta-elemene in vitro and in vivo was definite, and beta-elemene could improve the patient immunity and no sever side effect, drug resistance or bone marrow suppression were found during the clinical studies. And human serum albumin (HSA) is a primary extracellular protein which has a high concentration distribution in blood plasma and has many characteristic physiological functions. Therefore, the binding of beta-elemene to protein may be very important for absorption, distribution, metabolism and elimination. Therefore, the study on the interaction of beta-elemene with drug-carrying protein is very important. In this work, molecular binding of beta-elemene to human serum albumin (HSA) was investigated by using spectrofluorometer. the binding constants suggested that a strong interaction and the formation of a complex between beta-elemene and HSA. This clearly implies that beta-elemene can be stored and removed by the proteins in the body. Furthermore, the fluorescence quenching results showed that the HSA fluorescence was quenched by beta-elemene through static quenching mechanism. Thermodynamic parameters showed that hydrophobic interactions play a role in the binding of beta-elemene to HSA. The negative deltaH(0) and positive deltaS(0) in case of beta-elemene therefore showed that electrostatic attraction play a role in the binding of beta-elemene to HSA.

Objective To study and compare the protective effects of pmtease inhibitor and corticosteroid on endotoxin-indueed acute lung injury in order to guide the choice of appropriate drugs. Method Thirty-two New Zealand rabbits were randomly divided(random number) into four groups with 8 rabbits in each, namely normal controls(C) ; lipopolysaecharide(LPS) group(L) ; ulinastatin(UTI) group(U) and dexamcthasone(DEX) group (D) .Except group C, all rabbits were injected with a dose of LPS 600 μg/kg iv. Meanwhile the rabbits in group U,group D received UTI(100 000 μ/kg), DEX(5 mg/kg), respectively. The specimens were collected 4 hours later for detecting the levels of TNF-α and NO in serum, and blood gas analysis, histological manifestations, the lung wet/dry weight ratio, lung tissue MPO and SOD activity, lung tissue MDA. Data were analyzed by ANOVA (SNK- q test), and P < 0.05 was considered as significantly different. Results Compared with group C, the lungs of the rabbits in group L had inflammatory granulocyte infdtration, diffused alveolar septum thickening and hemorrhagic spots were observed in pathological examinations. The histological changes of group U and group D were much lessened than those in group L. As groups U and D were compared with group L, there were significant differences inmany biomarkers including lung wet/dry weight ratio[(5.02±0.11),(4.93±0.13) vs.(5.37 ±0.29)],lung tissue MPO activity[(0.51 ± 0.05),(0.54±0.07) vs.(0.82 ± 0.09)] and MDA[(0.82 ±0.05),(0.81 ±0.04) vs.(0.96±0.05)], NO[(296.2± 11.7),(291.7 ± 15.8) vs.(351.8±19.6)] and TNF-α[group D(2.021 ± 0.122) vs. group L(4.999 ± 0.139)],lung tissue SOD activity[(120.3 ± 6.1),(122.6±3.5) vs.(105.1 ± 8.5)] and blood gas analysis[pH(7.30±0.23),(7.30±0.17) vs.(7.22±0.45) and PaO_2( 101.9 ± 6.8).( 102.5 ± 4.7) vs.(80.3 ± 3.3)] ; but there were no differences of above mentioned biomarkers between group U and D( P > 0.05). And there were no significant differences in PaCO_2 betweeu group U and D and group L[(37.0 ± 3.3),(37.6 ± 3.0) vs.(34.8 ± 2.3)]( P > 0.05). Conclusions The protective effects of ulinastatin on endotoxin-induced acute lung injury is comparable to those of dexamethasone, thus the former may be a clinical substitute for the latter with less side effects.

Objective To explore the value of the LigaSure vessel sealing in laparoscopic nephrectomy surgery. Methods Laparoscopic nephreetomies were performed in 41 cases from May 2004 to December 2006 by using LigaSure, including simple nephrectomies, radical nephrectomies and nephroureterectomies. The operative time, estimated blood loss, open conversion rate, duration of postoperative drainage, total amount of postoperative drainage, postoperative hospital day as well as complication rate were recorded and analyzed retrospectively. Results All procedures were finished successfully without conversion to open surgery. No severe vascular complication or other serious complications happened. The mean operative time was 146min (range, 35-240 min) ; mean blood loss was 163ml (range, 30-450 ml); mean time for postoperative drainage was 3d (range, 1-6 d) ; mean amount of postoperative drainage was 229ml (range, 45-435 ml). The postoperative hospital staying was 6-21 d, with the average of 10 days. Conclusions The LigaSure vessel sealing system produees a consistent, reliable, permanent seal of veins, arteries, and tissue bundles. It could decrease operative time and blood loss. This new energy-based vessel-ligation device appears to be effective in advanced laparoscopic procedures.
