Aim To study the activation of Nrf2 in-duced by baicalein ( BAI ) , and its protection against carbon tetrachloride ( CCl4 ) , ethanol and acetamino-phen ( APAP )-induced hepatotoxicity. Methods A reporter gene assay was conducted in human normal liver L-02 cells to detect the activation of transcription factor Nrf2 induced by baicalein. APAP ( 10 mmol · L-1 ) , CCl4 (10 mmol·L-1 ) and Ethanol (100 mmol · L-1 ) were used to induce hepatotoxicity in L-02 cells. After the pre-incubation with Baicalein (0, 1, 10, 25, 50, 100 μmol·L-1 ) for 15 min, cells were administrated with or without those above hepatotoxins. 48 h later, cell viability was detected by 3-(4, 5-dim-ethylthiazol-2-yl ) 2 , 5-diphenyltetrazolium bromide (MTT) method. Results Baicalein (25, 50 μmol· L-1 ) induced the activation of Nrf2 ( P <0. 01 , P <0. 05) in the reporter gene assay. As compared with control, three hepatotoxins ( APAP, CCl4 , Ethanol ) all decreased cell viability ( P<0. 01 ) , and baicalein significantly reversed such decreases in a concentra-tion-dependent manner ( P<0. 01 ) . Conclusion Ba-icalein can induce the activation of transcription factor Nrf2 , which is probably one of the mechanisms con-tributing to the protection of baicalein against hepato-toxins (APAP, CCl4, Ethanol)-induced hepatotoxici-ty.

Objective To analyze the clinical features,curative effect and prognosis of extra-pulmonary infections by mycoplasma pneumoniae(MP).Methods ELISA was used to detect anti-MP IgM and IgG.Case histories of 226 patients,whose nasopharyneal lotione and respiratory secretions were positive of virus and bacteria respectively,was analysed retrospectively.Results One hundred and eighteen of the 226 (52.2%) cases suffered from extra-pulmonary infection.Of these infections 38.98%,33.89%,21.11% and 17.79% were found in digestive, urinary, cardiovascular systems and serous membrane respectively.All of the cases were improved after treatment with macrolides antibiotics.All cases were MP IgM positive,35.5% cases were IgG positive.Spatum MP positive rate was 32.2%.Positive rate of cold-agglutination test was 47.46%.Conclusions MP infection may cause many extra-pulmonary complications.When multi-organ infections can not be explained with bacterial and viral infections,MP infection should be considered.

OBJECTIVETo search all studies that had been published in the world with regarding to the effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complications and comparative functional outcomes in patients with giant cell tumours (GCT) of the distal radius and analyze them which were in high quality by means of Meta analysis, in order to give some evidences for the choice of method dealing with giant cell tumors GCT in surgery.

METHODSCochrane central register of controlled trials(Issue 8 2014), PubMed(1970-01-01/2013-01-01), Ovid (1970-01-01/2013- 01-01), Elsevier (1970-01-01/2013-01-01), CNKI (1970-01-01/2013-01-01) were searched. Including intralesional curettage and wide excision were performed to treat giant cell tumors (GCTs) of the distal radius in the literatures, selecting on meet eligibility in the standard literatures underwent strict quality assessment. The Meta-analysis was performed with software RevMan5.0 from the Cochrane collaboration. Additionally, the analysis checked the heterogeneity of data. The effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complication in patients with giant cell tumours of the distal radius were evaluated and Odds Ratio was calculated.

RESULTSSeven relevant articles were identified involving total 163 cases. Among them, 92 cases were intralesional curettage (PMMA, n = 54; bone graft, n = 33; no PMMA or bone grafts, n = 5) and 71 cases were wide excision. The patients in the intralesional curettage group had a higher recurrence rate [OR = 3.87, 95% CI (1.42, 10.53)],especially for Campanacci grade 3 GCTs [OR = 10.12, 95% CI (1.57, 65.27)], yet fewer major complications [OR = 0.13, 95% CI (0.04, 0.40)] than the wide excision group. The use of PMMA versus bone graft did not affect the recur- rence rate [OR = 0.96, 95% CI (0.26, 3.56)]. By selecting the system evaluation of MSTS, the VAS and dynamometer, the result showed that the intralesional curettage group was equivalent or preferable to wide excision in terms of function rehabilitation.

CONCLUSIONBased on data obtained from the limited number of studies available, intralesional curettage appears to be moreappropriate for the treatment of local lesions (Grade 1 and 2) than Grade 3 GCTs of the distal radius. Moreover, PMMA was not additionally effective as an adjuvant, the intralesional curettage group was found to be equivalent or preferable to wide excision in terms of function rehabilitation.

Objective To evaluate the value of combined hepatectomy in radical resection for hilar cholangiocarinoma. Methods The clinical data and follow-up data of 67 patients of resection for hilar cholangiocarinoma in Henan Tumor Hospital from June 2005 to october 2008 were retrospectively analyzed. Results According to intraoperative exploration situation and bismuth types, tumor resection was combined performed with hepatectomy (n＝38)or non-hepatectomy (n＝29). The rate of R0 resection was 55.3% in hepatectomy group(n＝21) and 34.5% in non-hepatectomy group(n＝10), and the difference was significant（P＝0.024）. The incidence of complications were 39.5% in hepatectomy group(n＝15) and 13.4% in non-hepatectomy group(n＝4), and one patient with liver and kidney failure died in hospital. The 1, 3, 5 years of survival rate were 89.3%,53.6% and 32.1% respectively in R0 group (n＝31) and 69.7%,30% and 10% respectively in R1～R2 group(n＝36), there were significant differences in the postoperative survival rate between both groups（P＝0.018). The 1, 3, 5 years of survival rate were 81.8%,48.5% and 24.2% in hepatectomy group and 75%,32% and 16% in non-hepatectomy group respectively, and the differences were significant（P＝0.037). Conclusions Aggressive resection including combined hepatectomy for hilar cholangiocarcinoma can play an important role for curative effect and long term survival rate.

TCM incompatibility means that the combinations of some Chinese materia medica would produce or enhance side effects, or even reduce or damage medicine efficacy. Therefore, clinical incompatibility should be avoided. The core idea of TCM incompatibility is "Eighteen Clashes" and "Nineteen Incompatibilities". China Pharmacopoeia clearly states that "Eighteen Clashes" and "Nineteen Incompatibilities" belong to incompatibility. This article summarized the incompatibility in TCM patent medicine used in Guang'anmen Hospital of Chinese Medicine Academy of Sciences, with a purpose to provide references for clinical doctors and pharmacists.
