Objective To observe the effect of the therapeutics of warming Yang and inducing diuresis with removing blood stasis and clearing away turbidness in retarding the course of chronic renal failure (CRF). Methods Sixty-five patients with CRF were randomly divided into the treated group (33 cases) and the control group (32 cases). Both groups were treated with low-protein diets,controlling hypertension and symptomatic treatment. And Chinese drugs for warming Yang and inducing diuresis with removing blood stasis and clearing away turbidness were given additionally to the treated group. The time (month) for doubling serum creatinine (SCr) level was taken to evaluate the speed of CRF progression. Results In the treated group,the time for SCr increased from (300.5?99.2) ?mol/L to (602.0?199.6) ?mol/L was (27.6?9.1) months,while in the control group,the time for SCr increased from (296.3?96.8) ?mol/L to (598.8?198.4) ?mol/L was (17.2?5.7) months. Comparision between the tow groups showed significant difference (P

Objective To discuss the incidence trends of hyperuricemia in people of different TCM constitutional types by analyzing the constitutional types of patients with hyperuricemia,and to lay a foundation for follow-up study in preventive and therapeutic measures for hyperuricemia.Methods 518 healthy people and 525 people of hyperuricemia were included in our research by identifying their TCM constitutional types by the self testing table of constitutional classification and determination of TCM promulgated by China Association of Chinese Medicine.Hyperuricemia's high-risk constitutional types were analyzed.Results People of dampness-heat constitution (24.57％),phlegm-dampness constitution (22.86％) and static-blood constitution (11.05％) were top 3 groups in occurrence rate of hyperuricemia,the risk ofhyperuricemia in these three groups above were significantly higher than the other constitutional types.On the contrary,the risk of hyperuricemia in the group of the mildly constitution (8.57％) and the group of qi-asthenia constitution (6.29％)were significantly lower than the other groups.Conclusion People of dampness-heat constitution,phlegm-dampness constitution and static-blood constitution were high risk groups of hyperuricemia,which deserved our attention in research of preventive and therapeutic measures for hyperuricemia.

Objective To obtain Chinese hamsterovary (CHO) cell line expressing human decay accelerating activity (hDAF) stably and to observe the protective effect of hDAF on heterologous cells under the circumstance of complement activation. Methods The eukaryotic expression vector DAF pcDNA3.1 was constructed and then transfected into CHO cells by lipofection. Monoclones of cells expressing hDAF stably were screened by the method of limiting dilution. hDAF expression was detected by flow cytometry. The decay accelerating activity of hDAF was determined by assay of C3 deposition and 51Cr release. Results The expression vector DAF pcDNA3.1 was successfully constructed, and monoclones of cells expressing hDAF were obtained. CHO cells expressing hDAF could decrease C3 deposition and attenuate the killing effect of activation of the complement system. Conclusion We have obtained CHO cell clones expressing hDAF stably, which is helpful for the further studies of the relationship of the structure with the functions of hDAF.

Objective To investigate the clinical value of intraoperative cholangiography( IOC) by cystic duct during laparoscopic chol-ecystectomy( LC) . Methods The clinical data of 58 patients with LC received intraoperative cholangiography by cystic duct were analyzed retrospectively. Results In this group,Successful treatment of 55 cases(94. 83%),failed in 3 cases(5. 17%),no common bile duct calculi in 50 cases(90. 91%),small common bile duct calculi(0. 4 cm) in 5 cases(9. 09%). Among them 4 cases were received common bile duct exploration via laparotomy,1 case treated by laparoscopic transcystic biliary calculus extraction with Dormia basket.

disorders,hypoxia,inflammation,vacuoles degeneration cells,increased cells apoptosis,aggravated damage of liver function and increased mortality of rats.Splenectomy could reduce PVP and then improve the liver tissues damage caused by liver congestion,meanwhile,increase the survival rate of rats.

Objective To evaluate the efficacy of point application combined with catgut implantation at acupoint for lung-distention. Methods A total of 122 patients with lung-distension were randomized into a treatment group (62 patients) and a control group (60 patients). The patients in the control group received conventional treatment, and those in the treatment group were additionally treated with point application combined with catgut implantation at acupoint on the basis of the control group for 4 weeks. At 6 months follow-up, pulmonary function including the forced expiratory volume in first second (FEV1) and the percentage of FEV1 to forced vital capacity (FEV1/FVC), the total effective rate and acute exacerbation rate were compared in both groups. Results The total effective rate in the treatment group was significantly higher than that in the control group (98.4%vs. 85.0%;χ2=5.592, P<0.05). There were no significant difference in the acute exacerbation rate between the treatment group and the control group (8.1%vs. 20.0%;χ2=3.358, P>0.05).The FEV1 (treatment group: 71.58% ± 2.23% vs. 59.98% ± 2.19%, t=29.223, P<0.01; control group: 66.99% ± 2.25% vs. 61.03% ± 2.50%, t=13.726, P<0.01) and the FEV1/FVC (treatment group:68.99%± 1.33%vs. 50.77%± 1.45%, t=72.914, P<0.01; control group: 62.67% ± 1.47% vs. 51.89% ± 1.88%, t=34.989, P<0.01) after the treatment were significantly increased compared with before the treatment in both groups and such improvement in the treatment group was greater in the treatment group than that in the control group (FEV1: t=13.726, P<0.01;FEV1/FVC:t=34.989, P<0.01).

In order to quantify the curing effects of phenanthridine on yeast prion, we introduced semi-denaturing agarose gel electrophoresis and fluorescence recovery after photobleaching techniques to quantify the curing effects of phenanthridine on yeast prion at the protein and cellular levels with the [PSI+] yeast strain expressing GFP-Sup35p (NGMC). The results showed that these two approaches could precisely quantify the curing effects of phenanthridine on [PSI+] cells. After a treatment for 1 through 5 days with phenanthridine, the curing rates of [PSI+] cells were 0%, 0%, 51.7%, 87.5% and 94.4%, respectively. Meanwhile, we quantified the sizes of Sup35p polymers in phenanthridine induced pink phenotype cells. The aggregation status in 1-2 days phenanthridine treated cells were similar to those in [PSI+] cells, while the aggregation status in 3-5 days phenanthridine treated cells were similar to those in [psi(-)] cells.
