Objective To study the effect of zinc on lipid peroxidation, anti-oxidase and development of rats. Methods 64 SD rats weight was(109.7?10.4) g, 32 male, 32 female were randomly divided into 4 groups. Every group was fed on the fodder contained zinc of different content for 40 days to build animal model. The Zn, Cu, Fe and MDA contents, SOD and GSH-Px activity in tissue of rats were determined. The One-way ANOVA test was used for multiple related samples and simple correlation analysis was used. Results Compared with 30 mg/kg group, the development of thighbones and the body weight of rats in groups with zinc exposure doses of 9 and 400 mg/kg bw were significantly retarded, the consumption rate of fodder was lower in male rats (P

Newly synthesized retinoic acid derivative-retinamide (RII) was employed as differentiation inducing agent. Cultured tumor cells of epithelial origin were exposed to 10-5mol/L RII for 5 passages. These cells included mouse fore stomach carcinoma (MFC, lung metastatic rate 85%), human nasopharyngeal carcinoma (CNE-2Z, 56%), and clonal variants from CNE-2Z, CNE2L2 (100%) and CNE2L4 (13%) . The results of serial observation were as follows. The growth, clone-forming ability, motility, invasiveness of these tumor cells were obviously inhibted. Their adhesion to fibronectin and laminin was increased. Morphological ultrastructure changes, mainly of surface structure, were also observed. These changes suggested that RII made metastatic cells less aggressive and showed a tendency toward differentiation. After exposured to RII, different changes of oncogene and antioncogene expression of these tumor cells were detected. For example, RE caused expression of nm23in MFC cells, but down regulated (decreased) its expression in CNE2L2 cells and similar changes of rasH, fos, nm23, Rb. Expression were observed for CNE-2Z cells and its clonal variants CNE2L2 CNE2ZL2. RII down regulated both these oncogene and antioncogenes in both CNE-2Z and CNE2L2, but up regulated all of them in CNE2L4. The results indicated that oncogene and antioncogene may play different roles in different tumor cells, the same factor (RII) may lead to different changes of gene-expression in different metastatic tumor cells. So the function of oncogene and antioncogene may be of relativity and may be influenced by multifactors. Our data were mostly from in vitro experiments. It could not be deduced completely to a level as a whole in vivo.

Objective To observe curative and side effects of fluconazole in preventing and treating fungal infection in patients with acute leukemia.Methods 112 cases patients with acute leukemia were divided into two groups.Group A was prevented group (25 cases).These patients had fluconazole by oral administration with 100 mg/d for 7 days when the peripheral white blood cell were less than 2.0×109/L.Group B was treated group (87 cases).These patients had intravenous drip fluconazole with 200 mg/d if they reach the fungal infection diagnosis standard.To observe the characters of fungal infection in acute leukemia,the occurrence ratio of fungal infection in these two groups and the side effects of fluconazole.Results The occurrence ratio of fungal infection in Group A and B had obvious difference.(χ2=4.21,P<0.05);Patients with acute leukemia were easily infected by fungal in gastrointestinal,respiratory and urinary systems.There is no sereve side effect observed in using fluconazole.Conclusion:Taking fluconazole by oral administration can safely and effectively prevent fungal infection in patients with acute leukemia.

Objective To compare effects of both ends of the injection cesarean section anesthesia differ-ences.Methods ASAⅠ-Ⅱgrade cesarean section 226 cases were selected and randomly divided into the observa-tion group and control group on the basis of number characterization.Observation group:After the success of epidural puncture needle oblique injection of 1.7% for the end of lidocaine carbonate 5mL,then needle bevel steering head end 3-5min without observing all spinal abnormalities such as re-injection of 5mL of 1.7% lidocaine carbonate,fol-lowed by epidural catheter inserted,modified supine position to continue after injection of 1.7% lidocaine carbonate 5mL;Control group:after the success of epidural catheter tip administered by traditional teaching methods.Two groups of maternal range block plane , intraoperative pain intensity and time of delivery of the fetus were recorded .intraoperative changes in vital signs and Apgar score after the fetus were observed.Results The block wide range for anesthesia of the observation group[(14.43 ±1.21)points]were significantly higher than that of the control group,and intraopera-tive pain was (1.61 ±0.92)points,fetal childbirth lengthwas (1.8 ±0.6)minutes,which were better than those in the control group(t=12.76,13.07,12.86,all P<0.05);The MAP,HR,R,SpO2 between the two groups showed no significant differences(F=4.32,2.73,3.54,3.06,all P<0.05);Intraoperative vital signs and Apgar score was con-firmed no difference between the two groups(all P>0.05).Conclusion Both ends of the epidural injection for ce-sarean section is better than the traditional mode of administration of anesthesia.

Objective:To investigate the effects of clinically achievable dose of lovastatin on prostate cancer PC3 cells.Methods:PC3 prostate cancer cells were treated with dimethyl sulfoxide(DMSO),or lovastain only,or lovastatin with mevalonic acid for 24,48 and 72 hours respectively.MTT assay was used to detect the cell viability.By means of [3H] thymidine incorporation tests,the effects of lovastatin on cell proliferation were analyzed.Western blot was used to detect activated casepase3,caspase7,and cleaved PARP(cPARP),the important molecules on the apoptosis pathway.Results:Cell proliferation of PC3 was significantly inhibited by 39.29%[(63.69%?3.69%) vs(102.98%?6.84%),P=0.000] after 48 h treatment with lovastatin at its clinically achievable dose of 2 ?mol/L.After 72 hours the cell proliferation was inhibited by 44.24% [(52.79%?9.88%) vs(97.03%?0.87%),P=0.048].The cell number was also markedly decreased(4.86?105 ? 0.10?105) vs(9.66?105?0.10?105),P=0.000] after 72 h treatment at this low concentration of 2 ?mol/L.The viability of PC3 cells was significantly decreased 50.12%(56.52%?6.40%) vs(106.64%?5.27%),P=0.000] and 60.05%(41.99%?11.64%) vs(102.94%?8.49%),P=0.000] after 48 h and 72 h treatment,respectively.In addition,2 ?mol/L lovastatin induced activation of casepase7 and led the death substrate PARP to cleavage.Conclusion:Clinically achievable dose of lovastatin inhibits prostate cancer PC3 cell proliferation and induces PC3 cell apoptosis.

Objective:To investigate the possibility and feasibility of the simultaneous coronary artery bypass grafting (CABG) with tumor excision in patients suffering from tumor combined with coronary artery disease(CAD). Methods:From August 2000 to July 2006, ten patients who were suspected of tumor (four patients suffered from urinary system tumor, two digestive system tumor, and four pulmonary tumor) with coronary artery disease were successfully treated by simultaneous surgeries. Surgical incisions were chose by the different tumor position. All carried on the CABG before tumor excision except one case. The two cases had cardiopulmonary bypass CABG, the rest eight had off-pump CABG. Follow-up was conducted after operation. Results:The combined operations were satisfied. There was no in-hospital mortality, no postoperative hemorrhage, no myocardial ischemia or infarction, with few complications. Postoperative in-hospital stay was 10-34 days, average 22.4 days. All discharged in cure. One patient lost the follow-up. Nine patients were followed up from six months to seven years three months. Two patients died from metastasis, and the others survived with satisfied follow-up without cardiovascular events. Conclusion:The simultaneous coronary artery bypass grafting with tumor excision for patients who suffer from either CAD with benign or malignant tumor is safe and feasible with satisfied short-and long-term survival.

ObjectiveTo investigate the clinical safety and validity of heterogeneous dermal acellular matrix graft (ACMG) for urethral reconstruction in patients.Methods Ten male patients aged 36( range,20 - 62),stricture length 6.9 cm ( range,3.0 - 15.0 cm),were treated with the ACMG material.During the operation,ACMG was sutured to a tubular graft or as a patch and replaced the defect urethra.Urinary catheter was inserted in the reconstructed urethra for 6 months.Then the outcomes of this operation method and whether there were rejections against the material were observed.Results All 10 patients could void through normal urethral,and no rejection was observed.Retrograde urethral visualization and urethroscope gave evidences of smooth urethral and continuous mucosa.The patients were followed up for 18months,and all patients voided normally except 2 cases needed urethral dilatation.ConclusionsHeterogeneous dermal ACMG for urethroplasty in men has the excellence of good biocompatibility,constructing the functional urethra.Additionally,this material could be manufactured with greater scale and advanced technology,which made it appropriate for operation of harder and longer urethral stricture diseases,serving as an ideal replacement material of urethra.
