Aim To study the effect of emodin on IL-8 secretion and NF-?B activation of HT-29 cells,and explore the molecular mechanism of emodin.Methods The cytotoxicity of emodin was assessed by WST;NF-?B activation was detected with co-focal microscopy by immunofluorescence;the production of IL-8 was investigated by ELISA.Results Emodin with the concentration of 10~80 ?mol?L-1 could decrease the mass production of IL-8 Secretion of HT-29 cells stimulated by IFN-?+LPS in a dose-dependent manner.Emodin with various concentrations could inhibit NF-?B activation dose-dependently.Conclusions Emodin inhibited IL-8 secretion and NF-?B activation of HT-29 cells stimulated by IFN-?+LPS.

Objective To investigate the clinical significance and changes of neuron-specific enolase (NSE) and S100 protein in blood serum in patients with enterovirus 71 infection.Methods A total of 176 children with enterovirus 71 infection admitted from March 1,2012 through October 31,2012 were enrolled for a prospective and control study.According to diagnostic criteria of the enterovirus 71 (EV71) infection instituted by expert consensus for treatment of severe patients sets in 2011,the patients were divided into three groups:mild group (n =62),severe group (n =65) and critically care group (n =49),and another 30 healthy children served as control group.The demographics of patients including age and sex were comparable between control group and the sick children groups.Four milliliter of peripheral blood were taken from ill children on the first day before treatment and on the first,second,third day after treatment.The blood samples of healthy children were taken on the first day after physical examination.At the same time,the clinical data of blood routine,blood biochemistry,myocardial enzymes and C-reactive protein during the first 24 hours were collected.Immunohistochemical technique was used to study the change of NSE and S100 levels in serum.Data were expressed in mean ± standard deviation ((x) ± s) and were statistically analyzed by using SPSS 13.0 statistical software.Comparisons were carried out among different groups with one way analysis of variance (ANOVA) and between groups were performed with the Student t test.Changes were considered as statistically significant if P values was less than 0.05.Results ①Compared with mild group and control group,the levels of NSE and S100 protein were significantly higher in severe group and critically care group (P ＜0.05).②The serum levels of NSE and S100 protein in severe group were higher than in those in mild group with better outcomes (P ＜ 0.05).Conclusion The serum levels of NSE and S100 protein as biomarkers can be used to evaluate the severity of EV71 infection,and can also be used to determine the efficacy of treatment.

Objective To evaluate the clinical value of CHO-hTSHR cells in detecting thyroid stimulating antibody (TSAb). Methods The cAMP production and TSAb activity were measured and cal-culated by stimulating CHO-hTSHR cell line with IgGs of normal control group and Graves" disease ( GD )group. TSAb positive standard was set to more than the mean + 2SD of TSAb activities in control subjects.The positive percentage of TSAb activity in GD group was calculated. Results The cAMP production and TSAb activities of GD group were higher than those of normal group[( 353. 65±126. 34 ) pmol/L vs (237.21±77. 15)pmol/L, ( 149. 08±53. 26)% vs ( 100±32. 52)%, P <0. 05] . The value that higher than 165% was set to be positive for TSAb. The positive percentage of TSAb in GD group was 50% ( 14/28). Conclusion CHO-hTSHR cell line constructed by our group is suitable for detecting TSAb activity in the sera of patients with GD.

Objective To evaluate the effects of Taoist cognitive psychotherapy on depression of aged patients with cerebral stroke hemiplegia convalescence. Methods Seventy-seven hemiplegia convalescence patients with depression were divided into general treatment group (38 patients, received general back-up psychology therapy) and combined treatment group (39 patients, received general back-up psychology therapy and Taoist cognitive psychotherapy) by random digits table. All patients were treated for 8 weeks and followed up for 6 months. Two groups were evaluated with HAMD and SS-QOL before treatment and at the end of the 2 weeks,4 weeks, 8 weeks and 6 months after treatment. The results were analyzed with statistics. Results In general treatment group, the HAMD scores were gradually decreased, and the HAMD scores of patients after 8 weeks' treatment were significantly lower than those before treatment[(22.35 ± 4.69)scores vs. (29.62 ± 5.95 ) scores,t = 6.425 ,P ＜ 0.01]. At the end of 6 months after treatment, the scores increased [(24.48 ± 4.12 ) scores vs. (22.35 ± 4.69 ) scores, t = 2.014, P ＜ 0.05], but they were lower than those before treatment(t = 4.836, P ＜ 0.01 ). At the end of 6 months after treatment, the SS-QOL scores were lower than those after 8 weeks' treatment (t =2.543,P ＜0.05),but they were higher than those before treatment (t = 2.790,P ＜ 0.05 ). In combined treatment group, the HAMD scores decreased continuously,and the scores after 8 weeks' treatment [(20.08 ± 4.60) scores] and 6 months' treatment [( 15.21 ± 3.42)scores] were significantly lower than those before treatment [( 30.14 ± 4.92 ) scores] (t = 8.341,15.443, P ＜0.01). Meanwhile,the HAMD scores after 6 months'treatment were significantly Iower than those after 8 weeks' treatment (t =4.724,P ＜ 0.01 ). The SS-QOL scores after 8 weeks' treatment [( 117.56 ± 26.22)scores] and 6 months' treatment [(126.57 ±21.82) scores] were significantly higher than those before treatment[(86.54 ± 23.90) scores] (t = 6.716,8.916,P ＜ 0.01 ) ,and there was significantly difference(t=2.378,P ＜ 0.05). The HAMD scores of combined treatment group after 8 weeks' and 6 months' treatment were significantly lower than those of general treatment group at the same time(t = 2.118, P ＜ 0.05 ;t = 8.405,P＜ 0.01 ) ,and SS-QOL scores were significantly higher than those of general treatment group at the same time (t = 3.123,P ＜ 0.05 ;t = 6.580,P ＜ 0.01 ). Conclusions General back-up psychology therapy combined with Taoist cognitive psychotherapy can improve depression and life quality of cerebral stroke hemiplegia convalescence in aged patients. The effects of Taoist cognitive psychotherapy is slower, but it is more beneficial in the long time.
