Objective:To study the influnence of elemene or heat shock treatment upon the expression of membrane HSP70 and HSPs genes in HepG 2 cells.Methods:HSP70 expression was observed by immunofluorescence and FCM techniques.HSP70 gene transcription was blocked by ActD.Genechip was used to study the expression of HSPs genes and the genes associated with the control of HSPs transcription.Results:The treatment of either elemene(50 ?g/ml,1 h) or heat shock(42℃,1 h)could increase the membrane expression of HSP70,ActD had a synergistic action with both treatments.HSP70EP(Enhancer Protein) gene was up regulated and HSPA2 gene was down regulated in both treatments.HSF1 gene was up regulated in heat shock treatment but down regulated in elemene treatment.The genes closely correlated with tumor immune,such as HSP70,HSP72,HSP75,HSP90 and gp96 were not changed.Conclusion:Comparing with heat shock treatment,elemene can cause a higher percent of HSP70 membrane expression in HepG 2 cells and that may be caused by its altering the distribution of the already existing HSP70 and/or accelerating the HSP70 mRNA translation.Both treatments can change the expression of genes associated with the transcription control factors of HSPs and decrease HSPA2 gene expression.

OBJECTIVE:
To investigate the effect and expression of the vascular cell adhesion molecule-1 (VCAM-1) in organs of rats died of anaphylactic shock.
METHODS:
The models of anaphylactic shock in rats were made and the immunohistochemistry of SABC was used to detect as follows: (1) The expression of VCAM-1 in rat lung, heart, brain, kidney, liver, spleen, stomach and intestine. (2) VCAM-1 levels in lungs at 10 min, 30 min after the allergic shock, and the time of death. (3) VCAM-1 levels in lungs of rats after the intervention of anti-VCAM-1.
RESULTS:
After the death, the expression VCAM-1 in lungs increased significantly relative to the control group and followed the extension of shock. In the rats which were injected with the anti-VCAM-1, the expression of VCAM-1 in lungs reduced.
CONCLUSION
(1) The expression of VCAM-1 shows difference in the various organs of rats after anaphylactic shock. The change of VCAM-1 is the most obvious in lungs and would increase followed the extension of anaphylactic shock. (2) After the anaphylactic shock, anti-VCAM-1 can inhibit the expression of VCAM-1 in rat lung.

Objective To explore the association between interleukin (IL)-28B variation and spontaneous clearance of hepatitis C virus (HCV) infection.MethodsA total of 280 HCV infected patients including 200 chronic hepatitis C (CHC) patients and 80 spontaneous clearance patients of HCV infection were enrolled in the study.The rs8099917 single nucleotide polymorphyism (SNP) of IL-28B gene was detected and the association between IL-28B variation and spontaneous clearance of HCV infection was analyzed.The data were compared using chi square test.ResultsThe genotype frequencies of TT and non TT (TG and GG) of IL-28B rs8099917 between CHC patients and spontaneous clearance patients were not significantly different ( x2 =15.874,P < 0.01 ). The prevalence of TT genotype in the spontaneous clearance group was 86.2%,which was higher than that in CHC group (62.0%).T and G allele frequencies in CHC group were 78.0% and 22.0%,respectively,and those in spontaneous clearance group were 92.5% and 7.5%,respectively,which indicated that T allele was dominant in spontaneous clearance patients. The allele frequency of rs8099917 was statistically different between the two groups (P<0.01).The spontaneous HCV clear rate in rs8099917 TT patients was 2.84 folds of non-TT patients,while the risk of chronicity of non-TT (TG+GG) patients was 1.36 folds of TT patients.Conclusion The IL-28B (rs8099917) TT genotype is associated with spontaneous clearance of HCV infection,which can be an important factor to predict the spontaneous clearance of HCV.

Objective To assess the causes of sildenafil failure and the feasibility of successfully rechallenging non-responding patients. Methods A total of 126 consecutive erectile dysfunction (ED) patients from Jan 2009 to Dec 2009 who claimed poor response to sildenafil (sildenafil 100 mg on demand, at lease 4 epiodes) were enrolled into the study. All patients received sexual reeducation and were treated with sildenafil, taken on a daily dose of 50 mg for 4 weeks. The International Index of Erectile Function-5 (IIEF-5), Rigiscan, serum testosterone or penile Doppler were used to evaluate ED and the cause of on-demand sildenafil failure. End point efficacy of rechallenging was evaluated using the IIEF-5 and the sexual encounter profile (SEP) 'Were you able to insert your penis into your partner's vagina?' and 'Did your erection last long enough to achieve successful intercourse?'. Results The recruited patients comprised of 41 cases with psychological ED, 39 cases with hypogonadism ED, 28 cases with diabetes mellitus ED and 18 cases with vascular ED. Compared with pretreatment and on-demand sildenafil baseline, daily administration of sildenafil significantly enhanced all efficacy outcome variables. The IIEF-5 was significantly improved after daily sildenafil (12.3 ± 2.9 vs18. 8±4.4, P<0.01), 78 patients responded to daily sildenafil. The overall salvage rate was 61.9%(78/126). Conclusions Sexual reeducation and daily administration of sildenafil may be able to salvage many patients with ED who were sildenafil non-responders.

Objective To estabalish a new conception, Erectile Dysfunction-no sexual life (ED-NS), so as create an evaluating questionnaire, Self-estimation Index of erectile function-No sexual life (SIEF-NS) so as to investigate its clinical reliability. Methods The conception of ED-NS was identified and the SIEF-NS questionnaire was established. Patients who complained of ED-NS and normal controls were enrolled into the research and assessed the erectile function was assessed with SIEF-NS.The SIEF-NS includes 12 questions, such as sexual libido, general erectile function, nocturnal penile erection, erectile function during foreplay, erectile function during audio-video sexual stimulation,confidence, depression, etc and each question has 5 point scales. Results Sixty-one ED-NS patients and 57 controls were enrolled into the study and assessed erectile function with SIEF-NS. The mean score of each question and integral score of SIEF-NS in ED-NS patients were significantly different from normal controls (P<0. 05). When the integral score was 35 points according to the ROC curve of integral score, the sensitivity of SIEF-NS was 88.5% and specificity was 96. 5%. Conclusions ED-NS is a new conception to define patients who have erectile dysfunction without sexual life. SIEFNS is suggested to be a useful method for the evaluation of ED-NS patients.
