A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.

OBJECTIVETo investigate the effects of bioactive glasses (BG) including 45S5 and nano-58S on proliferation, angiogenic markers vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) secretion and gene expression of human dental pulp cells (HDPC).
METHODSHDPC of 4th passage were cultured in Dulbecco's modified Eagle's medium (DMEM) which contained 0.1 g/L 45S5 or nano-58S ionic dissolution products. Meanwhile HDPC were cultured in DMEM without BG as control group. Proliferation of the cells was evaluated with methyl thiazolyl tetrazolium (MTT) assay on day 1, 2, 3. Quantitative real-time PCR and quantitative sandwich enzyme immunoassays were used to test VEGF and bFGF gene expression and protein secretion of HDPC on day 1, 2, 3.
RESULTSThe relative growth rate (RGR) of 45S5 and nano-58S groups were (134.5 ± 5.0)% and (146.3 ± 19.8)%, which was significantly different from that of control group (P < 0.05). The quantity of VEGF secretion of two experimental groups were (189.29 ± 4.64) and (216.18 ± 14.67) ng/L, respectively, significantly higher than that of the control group [(159.03 ± 11.69) ng/L] (P < 0.05). Furthermore, the nano-58S group secreted much more VEGF than 45S5 group (P < 0.05).bFGF secretion of HDPC was also enhanced by both 45S5 and nano-58S bioactive glasses. The VEGF gene expression of 45S5 and nano-58S on day 1 were (1.70 ± 0.19) and (1.63 ± 0.42), while the bFGF gene expressin on day 3 were (1.49 ± 0.02) and (2.30 ± 0.04), all significantly higher than that of control group (P < 0.05).
CONCLUSIONSBioactive glasses can enhance the proliferation, VEGF and bFGF secretion and gene expression of human dental pulp cells. Compared with 45S5, nano-58S showed a higher activation.

OBJECTIVETo evaluate the incidence of Ketoconazole associated hepatotoxicity and related factor.
METHODSLiterature retrieval was conducted by using multi-databases for meta-analysis on Ketoconazole associated hepatotoxicity. The data were collected with a standardized form. Overall estimation of incidence of hepatotoxicity for specific study type was calculated by using a DerSimonian-Laird random-effects model owing to the substantial differences among the studies.
RESULTSTotally 204 eligible studies were included in the analysis. The incidence of Ketoconazole associated hepatotoxicity was 3.6%-4.2%. The dosage and duration specific subgroup analyses did not show any significant difference among groups, while the age specific subgroup analysis showed the incidence in children and people aged >60 years was 1.4% (95% CI: 0.5%-4.2%) and 3.2% (95% CI: 1.1%-8.7%) respectively. Additionally, the incidence of the hepatotoxicity was higher in people who had oral administration of ketoconazole beyond the provisions of the usage instructions, and the incidence was 5.7% (95% CI: 4.5%-7.2%).
CONCLUSIONKetoconazole associated hepatotoxicity was common. Off-label use might increase the risk of liver damage. Well-designed large sample studies are needed to identify the risk factors in future.

The effect of arginine vasopressin (AVP) on membrane potential of neurons from dorsal root ganglion (DRG) was examined in the rat by means of intracellular recording technique. The results showed that (1) AVP induced hyperpolarization in the membrane of most DRG neurons. (2) The membrane conductance of the DRG neurons increased by 19.32% following application of AVP (p<0.05). (3) Perfusion with balance sodium solution (BSS) containing Cd(2+) (blocker of Ca(2+) channel) instead of Na+ failed to affect the AVP-induced membrane hyperpolarization of the DRG neurons (p> 0.05). After perfusion with BSS containing tetraethylammonium (TEA), however, the extent of AVP-induced hyperpolarization was reduced (p<0.05). (4) The AVP-induced hyperpolarization of the neurons was blocked by the antagonist of AVP V(1) receptors. The results demonstrate that AVP induces hyperpolarization of most DRG neurons, which might be caused by K(+) outflow mediated by AVP V(1) receptors in the membrane of the neurons.

OBJECTIVETo compare the efficacy, side effects and influence of two chemotherapy regimens, paclitaxel liposome combined with platinum and paclitaxel combined with platinum, on the survival rate in patients with cervical carcinoma receiving concurrent chemoradiotherapy.
METHODSOne hundred and sixty two cases with primary cervical carcinoma diagnosed and treated in the Jiangxi Maternal and Children Hospital between January 2008 and November 2009 were enrolled in this randomized controlled trial. Seventy one cases were included in the paclitaxel group and 91 in the paclitaxel liposome group. The chemotherapy doses were as followings: paclitaxel liposome and paclitaxel 135 mg/m(2); cisplatin 80 mg/m(2) or carboplatin AUC 4 - 6, repeated every 21 days for two or three times. Radical radiotherapy was given to both groups at the same time. The efficacy was evaluated by the tumor regression and the patients were followed-up for six months.
RESULTSThe overall response rates of paclitaxel group and paclitaxel liposome group were 90.1% and 89.0%, respectively (P > 0.05). The 1-year cumulative survival rate was 91.4% for the paclitaxel group and 89.2% for the paclitaxel liposom group (P > 0.05). The incidence rate of adverse effects such as rash, gastrointestinal toxicity, bone marrow suppression and muscle/joint pain in the paclitaxel liposome group was significantly lower than that in the paclitaxel group (P < 0.05), while there was no significant difference regarding the hair loss, liver damage, and peripheral neuritis (P > 0.05).
CONCLUSIONSPaclitaxel liposome plus platinum is a safe and effective therapeutic regimen for stage IIa-IV cervical carcinoma. However, the long-term efficacy of this regimen should be further observed.
