Niaodukang is an effective formula used in the second affiliated hospithal of Guangzhou Universityof TCM for chronic renal failure, which is composed of Rhizoma Rhei,Radix Polygoni Multiflori,Radix Astragali seu Hedysari and Fructus Ligustri Lucidi with the actions of supplementing qi, warmingYang, strengthening spleen, tonifying kidney, promoting blood circulation and removing turbid pathogenicfactor. To explore the effect of Niaodukang on the lipid metabolism of chronic renal faiure, rat model wasset up with improved technique of 5/6 kidney mass removal. After the accomplishment of the rat model for2 weeks, the models matched with the geneal conditions and 24 hours' proteinuria were randomly allocated to five groups: the model group,two Niaodukang groups with high and low dosages respectively, CoatedAldehyde Oxystarch group and the nounal control group. Serum contents of triglyceride, cholesterol andapoprotein were tested.The results showed that the blood lipid level in the model group was higher than thenormal group,and decreased markedly after the treatment of Niaodukang. It is indicated that Niaodukang exerts a good effect on the blood-lipid metabolism in rat model with chronic renal failure.

Abstract Objective:To observe and compare the effects of immune responses of HBV DNA caccine by insertion IL-2 gene.Try to ex-Plore the efficient way to enhance the immune effect of DNA vaccines. Methods:The recombinant expression plasmid vector peDNA3.1-S/IL-2with fusion gene of HBsAg and IL-2 cloned was constructed by PCR method and DNA recombinant technique.Then, it was transfered into Cos-7 cells by cation lyposomes and was detected its transient expressing product in vitro.At last,observed and compared the cellular and humoralimmune responses to HBsAg in C57BL/6 mice by intramuscular injection.Results:The pcDNA3. 1-S/IL-2 was constructed successfully by themethod of restriction endonucleases digestion, RCR and DNA sequencing. It can increase the titers of anti-HBs antibody. The bioactivity of IL-2and lymphocyte proliferation responses to HBsAg induced by the mouse spleen immunized with psDNA3.1-S/IL-2 were improved also. Conclu-sion:These results showed the expression of HBsAg-IL-2 fused gene can enhance the immune responses and suggested the insertion of IL-2 maybe a practicable way to enhance the DNA vaccine efficacy.

Objective To compare the changes of some blood indices after treatment of intertro-chanteric fractures with conventional and minimally invasive dynamic hip scres (DHS) internal fixation so as to understand the influence of minimally invasive technique on physiology of the organism. Meth-ods The elderly patients with intertrochanteric fractures in our department from July 2004 to May 2006 were divided randomly into two groups, ie, conventional DHS internal fixation group(Conventional group, 52 patients)and the minimally invasive DHS internal fixation group(Minimal invasion group, 54 patients). A comparison was done on data including white blood cells (WBC), hemoglobin (Hb), e-rythrocyte sedimentation rate (ESR). C reactive protein (CRP) and creatine kinase (CK) as well as re-cessive blood loss. Results The indices including transfusion, blood loss, recessive blood loss, ESR and CK in minimal invasion group showed less changes compared with conventional group. With statistical difference. But WBC and CRP showed no statisfical difference between both groups. Conclusion Minimally invasive DHS internal fvtation carl reduce operative trauma during treatment of intertrochanterie fractures in the elderly.
