To evaluate the effects of sevoflurane and isoflurane at 1.0 minimum alveolar concentration (MAC) on intracranial pressure(ICP) in patients undergoing craniotomy.Method:Sixteen patients without pre-existing increased ICP subjected to craniotomy for pituitary adenoma or craniopharyngioma were intubated with midazolam, fentanyl and atracurium.After intubation,midazolam and atracurium were pumped intravenously for 30 min.Then,sevoflurane or isoflurane was inhaled and the patients were randomly divided into two groups:A:1.0 MAC sevoflurane:B:1.0 MAC isoflurane.In the whole procedure,PaCO_2 with an average of 5.3 kPa was maintained. ICP was measured continuously by placement of a catheter into lumbar subarachoid space.Result:Sevoflurane maintained cerebral perfusion pressure slightly better than equipotent dose of isoflurane. During sevoflurane administration at 1.0 MAC.ICP decreased slighly,then increased gradually.However,ICP remained stable in group B.Conclusion:Sevoflurane and isoflurane at 1.0 MAC,Combined with midazolam and fentanyl,can be administered safely to the patients without preexisting increased ICP.

Objective To investigate the immunological activity and the effect of an anti－ keratin monoclonal antibody 5G5 on the proliferation of serum－ free cultured keratinocytes. Methods The reactivity of 5G5 with cultured keratinocytes was observed by immunohistohemistry technique. The keratins extracted from the cultured keratinocytes was identified by SDS－ PAGE and their reactivities with 5G5 were assessed by immunoblot analysis. MTT was used to study the influences of 5G5 on the proliferation of cultured keratinocytes. Results 5G5 recognized the band of keratin with molecular weight of 50 000 only. Positive staining of 5G5 was found in the cytoplasm of cultured keratinocytes. The strong potential of 5G5 to inhibit the proliferation of cultured keratinocytes was shown by MTT assay with dose－ dependent manner. Conclusions The antibody which specifically recognizes the keratin with molecular weight of 50 000 may be the effective component to inhibit the proliferation of cultured keratinocytes.

Objective To study the inhibitory effects of wild-type p53 on gastric cancer cell lines BGC-7901 and to explore the importance of wild-type p53 in gene therapy for gastric cancer. Methods Adenoviral vector with exogenous wild-type p53 gene was transfected into the gastric cancer cell line BGC-7901 which harbours a mutation in codon 204 of the p53 gene.The transfer efficiency and expression effect of p53 were examined by immunohistochemistry and in situ hybridization. The growth of BGC-7901 cells in vitro was determined by cell counting and MTT assay. Flow cytometric analysis was used for observing cell cycle.Results Transfer efficiency reached 100% in BGC-7901 cells when adenovirus infection ability was over 100MOI. 3 days after transfection, the introduction of exogenous wild-type p53 into the tumor cells resulted in decreased expression of the protein of mutant p53 and increased level of mRNA of wild-type p53 gene. The growth of the BGC-7901 cells was significantly slower after transfection with wild-type p53 gene than that before transfection. The percentage of G 1/G 0 phase of the cells with exogenous wild-type p53 gene was much higher than that of the cells without exogenous wild-type p53 gene.It was 56 47% and 79 40% respectively(P

Results There were significant differences between SJS group and conventional group in score of Chinese medical syndromes,serum level of leukocyte count,T-bet,GATA-3,Th1&Th2 cells in the pro-portion of whole CD4+Th cells and Th1/Th2 ratio(P<0.05 or P<0.01). There were no significant differences be-tween the two groups in serum level of CRP,PCT and GATA3. Compared with control group,there were signifi-cant differences in all indicators except GATA3 of the two groups(P<0.01). Conclusion Chinese herb Shengji-ang San has an effective benefits to Chinese medical syndromes,inflammatory reaction,the imbalance of serum Th1/T2 and related regulatory factors(T-bet&GATA-3)in sepsis patients.

Establishment of combination of disease and syndrome animal model is an ideal technology platform in TCM research. Currently, many scholars have prepared matching IBS animal models combined typical animal models with etiology, which em-bodies the advantages of syndrome differentiation and promotes the development of combination disease and syndrome animal model. Even though, there still exists some problems about sub-jective evaluation on syndromes, paying more attention on dis-ease and less on syndromes. Therefore, we should deepen the pathogenesis of diseases and TCM syndromes research on animal model replication and improve the method of construction of combination of disease and syndrome animal model through the biological research of combination of disease and syndrome sys-tem. By this way, the idea of preparation animal models will be more mature and the scientific connotation of TCM will be pres-ented more exactly.
