Objective To study the effect of Cap Nimodipine on the treatment of three kinds of cerebrovascular disease included acute ischemic cerebrovascular disease(AICVD),subarachroid hemorrahage(SAH),and multiple infarct dementia(MID).Method 103 cases were orally given cap nimodipine 30mg tid/d ,for 18 monthes. The efficacy was assessed by a double-blind placebo-controlled trial.Results ⑴ AICVD treating group comparing to placebo group, there was significant difference in effective rate,(P0 1).⑵SAH treating group compared with placebo group,we revealed that the cerebrovascular system (CVS) event rate and death rate decreased markedly (P

Objective To study effect of rubescens on inflammatory cytokines and liver function of alcoholic liver injury rat model.Methods 120 SD rats were chosed for studied, randomly divided into control group, model group and treatment group,40 rats per group.Alcoholic liver injury rat model was made by ethanol feeding approach, rubescens were given for treatment.Then serum AST, ALT, α-GST, GLDH content and liver tissue NF-κB, TNF-α, IL-6, IL-8 levels were detected by electrochemiluminescence and fluorescent quantitation PCR,respectively.Results Model group serum AST, ALT,α-GST, GLDH contents and NF-κB, TNF-α, IL-6, IL-8 contents in liver tissue were higher than control group(t=12.030~37.417, P<0.05). Treatment group serum AST,ALT, α-GST, GLDH contents and NF-κB, TNF-α, IL-6, IL-8 contents in liver tissue were lower than model group (t=5.128~32.325, P<0.05).Conclusion Alcohol feeding can cause liver damage, rubescens therapy can reduce liver injury, relieve inflammation.

Human herpes simplex virus 1 (HSV-1) causes facial,ocular,and encephalitic disease and is associated with latent infection and cancer.Here,we developed a means of studying the pathogenesis of HSV-1 infection at the protein level by using the SELDI Protein Chip to detect changes of protein expression in Vero cells cultured in vitro.After infection with HSV-1 and culture for 12,24 or 48 h,cells were harvested and lysed.IMAC3 arrays were applied to SELDI-TOF-MS to detect proteomic differences before and after infection.The chip detected a series of differentially expressed protein peaks.Interestingly,both peaks at 16 912 Da and 17 581 Da corresponded precisely with the molecular mass of ISG 15,which may participate in antiviral activity during the process of infection.Thus,the results we obtained can serve as a basis to study the pathogenesis of HSV-1 and the interaction between the virus and its host.In addition,they can help in the discovery of new therapeutic targets for treatment of HSV-1 infection.

Objective To study the correlation of ~(18)F-fluorodeoxyglucose (FDG) PET/CT with pathological changes of the VX2 rabbit tumors after treatment of Ar-He knife,and to explore the evolution of the Ar-He knife curative effect for VX2 rabbit tumors.Methods Thirty-six Japanese white rabbits had successfully been implanted with VX2 tumors in thighs.Four weeks later,the rabbits with VX2 tumors were imaged with FDG PET/CT before they were treated with Ar-He cryoablation.The rabbits were evenly and randomly divided into 6 groups (6 rabbits in each group) and imaged with FDG PET/CT respectively on the first day,third day,seventh day,fourteenth day,thirtieth day and sixtieth day after cryoablation.The rabbits in each group were sacriftced after post-treatment FDG PET/CT imaging for pathology and immunohistochemistry studies.The standardized uptake value (SUV) of tumor regions were calculated and compared with pathology and immunohistochemistry findings in the cryoablative area in each group.Paired-samples t-test and bivariate correlation analysis were evaluated by statistical software SPSS 16.0.Results After ArHe cryoablation,pathological changes of "necrosis-inflammatory response→organization" were found.On CT imaging,the tumors enlarged during 3-14 d after treatment and then shrank gradually.On FDG PET imaging,the maximum SUV (SUV_(max)) dropped dramatically on the first day after the operation(from 2.54±1.12 to 0.67±0.12),and increased slightly on the third day (1.71±0.82),and then continually dropped to 0.51±0.32 (60 d afterthe operation).The differences of SUV_(max) between pre-and after cryoablationin each stage were significant,respectively (t=5.471,8.716,11.388,5.713,7.144 and 7.213,all P＜0.05).The size and SUV_(max) of the targeting area did not correlate with each other(r=0.259,P=0.675).The change of the MVD closely correlated with SUV_(max)(r=0.865,P=0.032).Conclusion FDG PET/CT can reveal the pathological change of tumor tissue after Ar-He cryoablation therapy and therefore may be a potential tool for evaluating the curative effect of this treatment modality.

Objective To develop a network system for radiotherapy.Methods Delphi 6.0 lan- guage was used to program the system based on PACS through the model of client-server machine and local network.Data of different facilities were transferred among each other through Dicom 3.0 and Dicom RT pro- tocol.Results The main function of this system was a management software for radiotherapy,a PACS sys- tem,a TPS system and a therapeutic machine system.Conclusion The network system operates steadily with data safe and reliable,and is an important part of the information construction in the department of radio- therapy
