Animal model of aged rat nephrotoxicity was induced by i. p. administrationof gentamycin in a dose of 140mg/kg/day. Part of those rats were treated with CordycepsSinensis(CS), Epimedium(Ep) and Astragalus Membranaccus (AM) in form of decoc-tion per Os and others seryed as control. The results were summarized as. 1. The nephro-toxicity of gentamycin was aggrevated with age. CS, Ep and AM are effective drugs inpreventing the tdeular damage caused by gentamycin in rats. The pathological changes ofrenal tuoules of the rat groups which treated with CS, Ep and AM were less severe thanthat of the control. 2. CS, Ep and AM could prevent the decline of renal cortical Na~+-K~+-ATPase activity of aged rat induced by gentamycin.

Objective To observe the effect of botulinum toxin A combined with delivery autologous platelet rich plasma into skin with microneedle for facial rejuvenation.Methods 82 patients from our hospital treated for facial rejuvenation were randomly divided into observation group(41 cases)and control group(41 cases).The control group was given delivery autologous platelet rich plasma into skin with microneedle therapy.The observation group was treated with botulinum toxin A on the base of control group.After the treatment,the effect was observed.The facial skin moisture,skin elasticity,grease and spots were detected before and after treatment in the two groups.Before and after treatment,the role function,emotional function,social function,body function and the overall quality of life score were detected by the quality of life table.Observe all of the patients reaction duration of therapy.Results The total effective rate was 95.1% in observation group,significantly higher than the control group(P<0.05).After the treatment,the facial skin moisture and skin elasticity scores were(51.24±8.31)and(62.73±8.59)in observation group,significantly higher than the control group(P<0.05),while the grease and spots scores were(41.87±7.47)and(42.13±7.62)in observation group,significantly lower than the control group(P<0.05).After the treatment,the role function,emotional function,social function and the overall quality of life score were(71.08±8.75),(66.21±7.04),(81.80±13.42)and(75.18±7.97)in observation group,significantly higher than the control group(P<0.05),while the body function score was similar in the two groups(P>0.05).And there was no adverse reactions happened in the two groups.Conclusion Botulinum toxin A combined with delivery autologous platelet rich plasma into skin with microneedle for facial rejuvenation has a good effect and high safety.

Objective To explore the effect of bcl 2 in vascular smooth muscle cells(VSMC) apoptosis induced by nitric oxide(NO),we investigated the effect of NO on Bcl 2 protein expression in cultured vascular smooth muscle cells(VSMCs),and effect of Bcl 2 over expression on apoptosis is(VSMCs) induced by NO. Methods Cultured rat VSMCs at passage 5 to 8 were used for experiments,S nitroso N acetypenicillamine(SNAP) was used as NO donor.Cells were preincubated for 24-48 hours in special culture dish with conditioned medium to reach quiescent,and then incubated in conditioned medium containing 0 5 mmol/L SNAP.After 8 to 10 hours,the cells were fixed and Bcl 2 expression was analyzed by ACAS 570 through fluorescent immunochemistry.Vascular smooth muscle cells were transfected with bcl 2 gene through retrovirus to allow overexpression of Bcl 2 in VSMCs.Finally,we observed the apoptosis in normal VSMCs and VSMCs infected with bcl 2. Results SNAP downregulated Bcl 2 expression in VSMCs.PCR and Southern hybridization confirmed the integration of the bcl 2 retrovirus vector into vascular smooth muscle cells genomic DNA.And fluorescence immunohistochemistry confirmed that Bcl 2 protein was overexpressed in VSMCs infected with bcl 2.And ratio of apoptosis become lower in VSMCs infected with bcl 2. Conclusion bcl 2 can inhibit apoptosis of VSMCs induced by SNAP.It is suggested that downregulation of Bcl 2 protein is one of the ways in which SNAP induces VSMCs apoptosis,and apoptosis in VSMCs induced by SNAP is regulated by bcl 2.;

This paper aims to analyze Professor Guo Rongjuan's medication experience on insomnia therapy based on the Traditional Chinese Medicine (TCM) Inheritance Support Plat. First, TCM formulae prescribed by Professor Guo for insomnia therapy were collected from the TCM Inheritance Support Plat. Next, unsupervised data mining algorithms, including apriori, modified mutual-information, and entropy clustering of complex system were applied to obtain the frequencies for different herbs and identify the association rules among the herbs. Accordingly, we can gain new insights into Professor Guo's medication experience on insomnia therapy. Based on analysis of 3 084 formulae, we determined the frequencies for herbs in the formulae and identified the association rules among these herbs. At last, 41 core combinations and 7 new formulae were obtained. The identified medication experience conform with Professor Guo's views on the etiology and pathogenesis of insomnia: "pathogenic fire derived from stagnation of liver-QI (Gan Yu Hua Huo)" is the core pathogenesis of insomnia; "liver stagnation and spleen deficiency" and "chronic illness transferred to kidney" are the main features for insomnia. The TCM Inheritance Support Plat is of great practical value for mining clinical experience of famous TCM doctors.

[Objective]To probe into the causes and treatments in the radial nerve injury.[Method]Twenty-nine patients with radial nerve injury were treated.Conservative measures were anti-inflammatory,repercussion,nervous pharmacotherapy,acupuncture and physiotherapy.Surgical interventions included open reduction and internal fixation,tenorrhapy,neurorrhaphy and decompression of nerve.[Result]The outcome of treatment was evaluated with the result of 19 excellent,8 good and 2 fair,in which nerve healing period was at an average of 4 months.[Conclusion]The overall effect was satisfactory in this series,among which,electro-neurogram were inconsistent with their symptoms and signs.It is important to asses the quality and degree in injury to the nerve for guiding the treatment.During internal fixation of the fractures of humerus,the exclusion and protection of the radial nerve should be carefully done.when removig the fixation the radial nerve would be protected by first dissecting normal radial nerve in distal and proximal segments,then,exposing gradually adherent segment within the scar tissue.In brief,the opportunity of injury to the radial nerve may be reduced by careful operation.

In order to evaluate the post-traumatic changes of serum levels of interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF_?) and their relationship to the occurance of multiple system organ failure (MSOF), 80 adult patients with severe multiple trauma(SMT), injury severity score(ISS) 32?14. served as the tested subjects. of which 50 cases received operations and the other did not. Thirty adult patient, scheduled for elective abdominal surgery, were randomly chosen as trauma control, and 20 healthy blood donors acted as normal control. The venous blood samples were taken on that day of injury, 3, 10 and 20 days post-traumatically, and immediately before dis charge. to measure serum concentrations of IL-6 by immunocytochemistry method and TNF_? by enzymo-immunoassay, respectively. The diagnosis of post-traumatic MSOF was made according to Baue's criteria. As compared with normal control levels, the concentrations of IL-6 and TFN_?, increased significantly in patients with SMT(P0.05). In comparison correspondingly with those of trauma control, the levels of IL-6 and TFN_? were elevated markedly (P
