RESUMEN
OBJECTIVE:To study the effects of high-mobility group box 1 protein(HMGB1) -mediated inflammatory pathway HMGB1-Toll like receptor 4 (TLR4) /nuclear transcription factor κ B(NF-κ B)on liver injury of rats induced by Tripterygium wilfordii,and to provide reference for clarify the mechanism of liver injury induced by T.wilfordii. METHODS:Totally 24 SD rats were randomly divided into blank group(normal saline,i. g. ),T. wilfordii group(16 g/kg by crude drug,i. g. )and neutralizer group(16 g/kg T. wilfordii crude drug i. g. after i. p injection of 100 mg/kg Ammonium glycyrrhizinate solution 3 h),with 8 rats in each group. All rats were treated for consecutive 3 weeks. The serum levels of AST and ALT in rats were detected every week. After the end of medication,the serum levels of HMGB1,IL-1β,IL-2 and TNF-α were detected by ELISA method;the protein expression of HMGB1,NF-κB p65 and TLR4 in liver tissue of rats were detected by Western blot assay. The pathological changes of liver tissue in rats were measured with HE staining method. RESULTS:After 3 weeks of treatment,the serum levels of AST, ALT,HMGB1,IL-1β,IL-2 and TNF-α in rats,the protein expression of HMGB1,NF-κB p65 and TLR4 in liver tissue of rats in T. wilfordii group were significantly higher than blank group and neutralizer group(P<0. 05 or P<0. 01). Hepatocyte edema was found around the central vein of the liver,and circular vacuoles were seen in some hepatic cytoplasm in T. wilfordii group;only varying size of vacuoles were found in a small number of cells in neutralizer group. CONCLUSIONS:T. wilfordii induced liver injury may be associated with the activation of HMGB1-TLR4/NF-κB inflammation pathway.

RESUMEN
Objective In order to investigate the situation application of compound Danshen injection (CDI) in the treatment and to provide reference for clinical rational use.Methods Adverse drug reactions (ADR) report literatures through WANFANG DATA, VIP DATA and CNKI from 1989 to 2013 with (CDI) were retrieved the data including patient age, gender, medical history, dosage, medication time and ADR type were got and analyzed.Results One hundred and twenty-one literatures with one hundred and forty-eight ADR report cases wore retrieved. The ADR of (CDI) rate of male was higher than female. The original disease causes were cardiovascular and cerebrovascular diseases. The age, a rather elderly bunch, was not associated with the disease. The frequent onest time of adverse reaction was in 5-20 min after medication, and allergic reaction was the main adverse reaction.Conclusion The ADR of CDI should not be ignored. Patients constitution, gender, medication time and the combined application should be pay more attention to reduce the incidence of ADR and ensure the drug safety.

RESUMEN
OBJECTIVE:To systematically review the efficacy of Berberine hydrochloride tablet in the treatment of non-alco-holic fatty liver disease(NAFLD),and provide evidence-based reference for the clinical treatment. METHODS:Retrieved from CJFD,Wanfang Database,VIP,CBM and PubMed,observational studies about Berberine hydrochloride tablet in the treatment of NAFLD were collected. After data extraction and quality evaluation,Meta-analysis was performed by using Rev Man 5.3 statistics software. RESULTS:A total of 6 studies were included,involving 294 patients. Results of Meta-analysis showed Berberine hydro-chloride tablet could significantly reduce the levels of AST[WMD=18.97,95%CI(2.25,35.70),P=0.03],ALT[WMD=31.04, 95%CI(7.17,54.91),P=0.01],TG[WMD=1.07,95%CI(0.39,1.74),P=0.002] and TC[WMD=1.31,95%CI(0.79,1.84),P<0.001] in the serum of patients with NAFLD. There were significant differences. CONCLUSIONS:Berberine hydrochloride tablet can significantly improve the liver function and blood lipid levels of patients with NAFLD,and the clinical efficacy is relatively pre-cise. Due to the limit of methodological quality,it remains to be further verified by large-scale and high quality RCT.
RESUMEN
The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.

RESUMEN
The paper is to report the establishment of a method for quickly evaluating compatibility of Chinese medicines injections. Isothermal titration calorimetry (ITC) was used to evaluate compatibility of Yiqifumai (YQFM) and vitamin C injection (Vc)/5% glucose injection (5% GS). The diversification of Gibbs free energy (deltaG), enthalpy (deltaH) and entropy (deltaS) were used to decide reaction types of colliquefaction procedures of different injections. The reactive profiles were used to determine signs and quantity of heat. And high performance liquid chromatography (HPLC) was used as a supportive method for ITC. Then, feasible binding sites were analyzed based on the information of spatial structures of major compositions. During the colliquefaction procedure of YQFM and Vc, [deltaH] > T[deltaS], so, the reaction is enthalpy-driving. And the reactive profile showed that a big deal of heat was given out during the procedure. Obviously, chemical reactions happened and the major compositions changed. On the other side, the reaction of YQFM mixed with 5% GS was entropy-driving, because [deltaH] < T[deltaS]. The reactive profile showed there was a little heat gave out. So, non-chemical reactions happened, and the major compositions did not change. The conformity existed between the results of ITC and HPLC. ITC could be used to evaluate the compatibility of Chinese medicines injections because of the advantages of ITC, such as real time, fast, sensitive and having more parameters.
