OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.

METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.

RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).

CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.

OBJECTIVETo study the center effect discrepancy in the multi-center clinical trials.

METHODSTwo groups of data collected from the multi-center clinical trials were used. Data were processed by covariance analysis and Meta-analysis.

RESULTSIn the covariance analysis, the discrepancy of the center effect values indicated statistical significance. Through Meta-analysis on fixed effect model, the discrepancy in one heterogeneity test showed no statistical significance (P > 0.05) while the inter-group discrepancy of the merged effect values drawn from analysis based on fixed effect model having statistical significance (P < 0.05). In the random effect model, the discrepancy in one heterogeneity test showed statistical significance (P < 0.05) while the inter-group discrepancy of the merged effect values drawn from analysis based on random effect model having no statistical significance (P > 0.05).

CONCLUSIONSStudies on multi-center random controlled clinical trials, when statistical significance was found in the interaction discrepancy between the inter-center and the center-group relation, the merged effect values should be compared and analyzed by an appropriate statistic model based on the heterogeneous test results from the Meta-analysis. However, if the result from covariance analysis and the one from Meta-analysis did not agree to each other, the results drawn from the Meta-analysis were reliable.

Aim To study the anti-inflammatory activ¬ity of diterpenes from Tripterygium wilfordii on lipopo- lysaccharide ( LPS)-induced macrophage and its mech¬anism. Methods MTT assay was used to detect the cytotoxicity of compounds. The Griess method was used to detect the NO on LPS-induced RAW264. 7 cells. ELISA was applied to determine the contents of inter- leukin 6 (IL-6) , tumor necrosis factor a ( TNF-a ) , interleukin lp (IL-lfj) and interleukin 18 (IL-18) in cell culture supernatant. Western blot was used to de¬tect IkBcx, .INK, ERK, p38, STAT3 and their phos-phorylation in LPS-induced RAW264.7, as well as the effect on COX-2, iNOS, NLRP3, caspase-1 , cleaved- caspase-1. Flow cytometry was employed to detect the effects of compounds on the phagocytosis of RAW 264. 7 cells. Results Hypoglicin II (1) and ent-pimara-8 (14) , 15-diene-19-ol (6) , two diterpenoid compounds from Tripterygium wilfordii could effectively inhibit the expression of inflammatory mediators ( COX-2 and iN- OS) and inflammatory cytokines (IL-6, IL-lp, IL- 18) in LPS-induced RAW264. 7 cells. Further re¬search found that the phosphorylation of IkBcx , JNK, ERK, P38, STAT3 and NLRP3 was all inhibited; however, there was no significant effect on the expres¬sion of IkBcx, JNK, ERK, P38 and STAT3. At the same time, they also inhibited the phagocytosis of mac-rophages. Conclusions The anti-inflammatory mecha¬nism of Tripterygium wilfordii diterpenoids 1 and 6 might be through inhibiting the production of NLRP3 inflammatory bodies, inflammatory mediators (COX-2 and iNOS) and inflammatory cytokines (IL-6, IL-lp and IL-18) , which is closely related to inhibiting the activation of MAPK, NF-kB and STAT3 pathway.

INTRODUCTIONMost hepatocellular carcinomas (HCC) develop in a background of underlying liver disease including chronic hepatitis B. However, the effect of antiviral therapy on the long-term outcome of patients with hepatitis B virus (HBV)-related HCC treated with chemoembolization is unclear. This study aimed to evaluate the survival benefits of anti-HBV therapy after chemoembolization for patients with HBV-related HCC.

METHODSA total of 224 HCC patients who successfully underwent chemoembolization were identified, and their survival and other relevant clinical data were reviewed. Kaplan-Meier and Cox regression analyses were performed to validate possible effects of antiviral treatment on overall survival (OS).

RESULTSThe median survival time (MST) was 15.9 (95% confidence interval [CI], 9.5-27.7) months in the antiviral group and 9.6 (95% CI, 7.8-13.7) months in the non-antiviral group (log-rank test, P = 0.044). Cox multivariate analysis revealed that antiviral treatment was a prognostic factor for OS (P = 0.008). Additionally, a further analysis was based on the stratification of the TNM tumor stages. In the subgroup of early stages, MST was significantly longer in the antiviral-treatment group than in the non-antiviral group (61.8 months [95% CI, 34.8 months to beyond the follow-up period] versus 26.2 [95% CI, 14.5-37.7] months, P = 0.012). Multivariate analysis identified antiviral treatment as a prognostic factor for OS in the early-stage subgroup (P = 0.006). However, in the subgroup of advanced stages, MST of the antiviral-treated group was comparable to that of the non-antiviral group (8.4 [95% CI, 5.2-13.5] months versus 7.4 [95% CI, 5.9-9.3] months, P = 0.219). Multivariate analysis did not indicate that antiviral treatment was a significant prognostic factor in this subgroup.

CONCLUSIONAntiviral treatment is associated with prolonged OS time after chemoembolization for HCC, especially in patients with early-stage tumors.
