Objective To study the clinic effects and safety of budesonide suspension combined with tubertaline solution for nebulization therapy on infantile asthma.Methods Seventy-five cases with asthma were divided into 3 groups randomly,double-blinded and controlled,each group having 25 cases.Group A inhaling tubertaline solution(bricanyl),while group B inhaling pulmicort respules combined with bricanyl,group C inhaling budesonide suspension(pulmicort respules)only.Results In group A,16 cases was cure,3 cases was markedly improved,6 cases was failure,the total efficacy rate was 76 percent.In group B,22 cases was cure,2 cases was markedly improved,1 case failed,the total efficacy rate was 96 percent.While in group C,14 cases was cure,4 cases was markedly improved,7 cases failed,the total efficacy rate was 72 percent.The difference of efficacy rate between group A and group B was significant(P0.05).Conclusion Pulmicort respules combined with bricanyl for nebulising inhalation is effective and safety on infantile asthma and its effect is better than inhaling bude-sonide or tubertaline only.

Objective To explore the acute toxicity and LD 50 of Tripterygium Hypoglaucum (Levl) Hutch(THH) solution to provide information for safe clinical application. Methods After oral administration of THH solution in mice, the mortality and the physiological and pathological changes were observed. Results The LD 50 (95% confidence limit) of THH in male and female mice was 79 g/kg(69～89 g/kg) and 100 g/kg (90～112 g/kg), respectively. No marked pathological change of the organs was found. Conclusion According to the standard of grading of acute toxicity, THH solution belongs to the moderate class. Therefore, it is safe in clinical practice and has a wide application.

Objective To investigate the effects of preventive chemotherapy for hepatocellular carcinoma (HCC) exceeding Milan criteria after liver transplantation. Methods The clinical data of 243 patients who had undergone orthotopic liver transplantation for HCC exceeding Milan criteria from April 2001 to July 2007 were retrospectively analyzed. Of all patients, 162 received preventive chemotherapy after transplantation. Results The 1- and 3-year survival rates and disease-free survival rates were not statistically different between patients who had received chemotherapy (78.5%, 63.7% ; 76.8%, 52.5% ) and those without chemotherapy (56.6%, 39.1%; 69.3%, 64.7% ) (X2 = 3.084, 0.444, P > 0.05). Cox regression analysis demonstrated that postoperative chemotherapy was not an independent factor affecting the survival rates of HCC patients without vascular invasion, but an independent factor affecting the survival rates of HCC patients with vascular invasion. Conclusions Early preventive chemotherapy could obviously increase the survival rate and delay the tumor recurrence of patients with HCC exceeding Milan criteria, especially for HCC patients with vascular invasion.

ObjectiveTo investigate the effects of moxa smoke versus tobaccosmoke on autonomous behaviors and hippocampal expression of glial fibrillary acidic protein (GFAP) in apolipoprotein E gene knockout (ApoE-/-) mice.Method Thirteen 8-week-old C57BL/6 mice constituted a blank control group. Twenty-seven ApoE-/-mice of the same age were randomized into ApoE-/-model, moxa smoke and tobacco smoke groups. The tobacco smoke and moxa smoke groups of mice were exposed to smoke 5-15 mg/m3circumstances. Every group of mice was intervened in 20 min. daily, six days a week, for atotal of 12 weeks. A behavioral test was conducted in week 13. The animals were then sacrificed to take the materials. Hippocampal GFAP in the brain was measured by an immunohistochemical method.ResultAutonomous activities were significantly more in theblank group than in the model group (P<0.05) and significantly fewer in the tobacco smoke group than in the blank group (P<0.05). There was no statistically significant difference in autonomous activities between the tobacco smoke group and the model or moxa smoke group (P>0.05). Moving distance was longer in the moxa smoke group than in the model group (P<0.05). Standing-up number was smaller in the moxa smoke group than in the blank group (P<0.05). Integral optical density of GFAP immune reaction products in the hippocampus was significantlyhigher in the model group of mice than in the blank and moxa smoke groups (P<0.05). Hippocampal GFAP expression was significantly higher in the group of mice than in the moxa smoke and blank groups (P<0.05).Conclusion Moxa smoke can increase the excitability of central nervous system in mice and reduce hippocampal GFAP expression in a mice model of Alzheimer disease.

To investigate the effects of Xinji' erkang (XJEK), a compound Chinese herbal medicine, on isoproterenol-induced ventricular remodeling in mice.

Objective To express the capsid proteins of WU polyomavirus(WUPyV) for research and find antigen for diagnostic value. Methods Coding sequences of capsid proteins of WU polyomavirus by PCR were cloned in prokaryotic expression vector PGEX-20T. Recombinant plasmids were transformed into E. coli BL21(DE3) and induced by IPTG for proteins expression. Recombinant proteins were identified by Western blot. Results SDS-PAGE proved that recombinant proteins showed three bands with molecular relative mass of 69×103, 63×103 and 56×103. The recombinant proteins were recognized by anti-GST McAb. The antigenicity was tested by Western blot using 16 WU polyomavirus positive and 70 negative sera. Conclusion Recombinant VP1, VP2 and VP3 expressed in E. coli can combine with WUPyV-Ab and have good antigenicity. They can be used for further research.

OBJECTIVETo evaluate the clinical effect of removing dampness and purgative (RDP) method in treating acute, subacute and chronic severe hepatitis.

METHODSOne hundred and twenty cases of severe hepatitis were randomly assigned to 2 groups, 60 patients in the control group were treated with routine Western medicine, 60 patients in the treatment group were treated with the same Western medicine plus Chinese medicine prescribed based on RDP principle orally and/or via enema. Fourteen days of treatment constituted one therapeutic course, and patients were treated for 3 courses. Changes of clinical symptoms and signs, complication occurrence, liver function, serum markers of hepatitis B virus, and some biological indexes were observed and compared. The case fatality rate was compared after a 6-month follow-up.

RESULTSThe total effective rate and marked improving rate in the treatment group was 71.7% (43/60 cases) and 48.3% (29/60 cases) respectively, while those in the control group, 51.7% (31/60 cases) and 20.0% (12/60 cases) respectively, showing significant difference between the two groups (P < 0.05). After treatment, the clinical symptoms and signs were relieved and complications were reduced in the treatment group, showing marked improvement as compared with that in the control group (P < 0.05). ALT, AST, TBil, quantitative titer of HBV-DNA and HBeAg decreased markedly, and ALB, prothrom-base activity (PTA) and total cholesterol (TC) increased significantly in both groups after treatment (P < 0.01). Significant difference was found in AST, TBil, PTA and quantitative titer of HBV-DNA between the two groups (P < 0.05, P < 0.01). In the 6-month follow-up, the case fatality rate was 23.3% (14/60 cases) in the treatment group, significantly lower than that in the control group (P < 0.05), which was 41.6% (25/60 case)

CONCLUSIONRDP treatment is helpful to improve the prognosis of patients with severe hepatitis, it is one of the effective measures for enhancing the efficacy of comprehensive treatment.

Based on the transcriptome data, we cloned the open reading frame of IiHCT gene from Isatis indigotica, and then performed bioinformatic analysis of the sequence. Further, we detected expression pattern in specific organs and hairy roots treated methyl jasmonate( MeJA) by RT-PCR. The IiHCT gene contains a 1 290 bp open reading frame( ORF) encoding a polypeptide of 430 amino acids. The predicted isoelectric point( pI) was 5.7, a calculated molecular weight was about 47.68 kDa. IiHCT was mainly expressed in stem and undetectable in young root, leaf and flower bud. After the treatment of MeJA, the relative expression level of IiHCT increased rapidly. The expression level of IiHCT was the highest at 4 h and maintained two fold to control during 24 h. In this study, cloning of IiHCT laid the foundation for illustrating the biosynthesis mechanism of phenylpropanoids in I. indigotica.
