Evidence-based medicine is advocated by WHO and adopted by developed countries for many years. In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione. Evidence was provided for relevant sectors such as Ministry for Human Resources and Social Security of the People's Republic of China and National Health and Family Planning Commission of the People's Republic of China to select and renew the Essential Medicine List (EML), the new rural cooperative medical scheme in China (NRCMS) list or the reimbursement list of industrial injury insurance. A total of 189 patients with initial pulmonary tuberculosis were divided into four groups who took antituberculotics combined with Jian'ganle, Hugan Pian, glucuronolactone and reduced glutathione respectively. Their liver function profile including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (A) and globulin (G) were detected at admission as baseline and after treatment. The Jian'ganle group was compared with the three others by chi-square tests. In an aspect of maintaining bilirubin indexes normal, Jian'ganle was more efficacious than glucuronolactone. And Jian'ganle had a little more efficacy than reduced glutathione to maintain protein indexes normal as well. And the therapeutic regimen of antituberculotics combined with Jian'ganle was the best in treating tuberculosis and preventing DILI at the same time. The study showed that among the four hepatinicas which demonstrated similar prevention of DILI caused by antituberculotics, Jian'ganle has more advantages over the three others to some extent, which provides a reliable basis for health sectors to select and renew the EML, NRCMS List or the reimbursement list of industrial injury insurance.

Objective To understand the underlying mechanism of mites-induced pediatric asthma by bioinformatic analysis on speciifc microRNA (miRNA) array and target gene screening. Methods This is a case control study of 62 pairs of dust mites-induced asthma children with age and gender matched healthy controls. Twelve pairs were randomly selected for miRNA array. The abnormal expression of miRNAs was compared between asthma and control children. The results were validated by RT-qPCR and bioinformatic analysis in remaining pairs of children. Results Six miRNAs (miRNA-151a-5p, 625-5p, 126-3p, 513a-5p, 27b-3p, 22-3p) were signiifcantly down-regulated more than two folds in dust mites-induced asthma children than those in controls. The enriched bioinformatics analysis showed that these miRNAs and their target genes CBL, PPARGC1B, ESR1, ONECUT2, EGFR, SYK, and STAT1 were related to inlfammatory cytokine signaling pathway. Conclusion It is suggested that miR-22-3p, 513a-5p, 625-5p, 27b-3p, and miRNA-target genes form a network through co-regulation to target genes to participate dust mites-induced asthma in children.

Objective To investigate the effects of Tanshinone Ⅱ A (extracted from Chinese herb medicine Salvia miltiorrhiza Bge.) on ventricular arrhythmias of rabbit hearts induced by ischemia in order to illuminate its mechanism of anti-arrhythmia.Methods Thirty rabbits were randomly (random number)divided into normal group,ischemic group and Tanshinone Ⅱ A group.Model of wedge shaped mass of rabbit left ventricular myocardium with coronary perfusion was prepared,and then by using floating glassy microelectrode,the trans-mural ECG,QT interval,the trans-mural dispersion of re-polarization (TDR) and trans-membrane action potentials from both endocardium and epicardium were simultaneously and wholly recorded.The incidence of ventricular arrhythmia in myocardium was observed after ischemia for thirty min.Results Under the condition of acute ischemia,compared with normal group,the incidence of ventricular arrhythmia and TDR were significantly increased in ischemia group (P ＜ 0.01),while incidence of ventricular arrhythmia and TDR were significantly reduced in tanshinone ⅡA group compared with ischemia group (P ＜ 0.05).The incidences of ventricular arrhythmia in normal,ischemia and Tanshinone Ⅱ A groups were 0/10,9/10 and 2/10 respectively.Conclusions Tanshinone Ⅱ A prevents ventricular arrhythmia and reduces TDR significantly in ischemic rabbit hearts.

Objective To observe the expression of bcl-2 gene in cell apoptosis of neonatal rats followed by hypoxic-ischemic brain damage(HIBD) and investigate the mechanism of neuronal apoptosis after HIBD.Methods Fifty-four neonatal SD rats were used in 1 sham-operated group and 8 trial groups. The models of HIBD were established in neonatal rats by inhaling the mixed gases of 92 % N 2 and 8 % O 2, the animals were sacrificed by dislocation their heads at different time points(0.5,1,3,6,12,24,48,72 h), the hippocampus were dissected for morphological analysis. The neuronal apoptosis and the expression of bcl-2 gene in hippocampus were detected by the methods of immunohistochemistry. Results The apoptotic cells appeared at the time point of 3 h, and reached the peak at 48 h, then decreased. The positive cell of bcl-2 protein increased from the time point of 30 min and reached the peak at 6 h and then decreased gradually following HIBD. Conclusion The expression of bcl-2 gene plays a role in the process of neuronal apoptosis following HIBD.

Objective To investigate the expression and significance of tumor necorisis factor related apoptosis induled ligand receptor(TRAILR) in human craniopharyngioma.Methods The expression of TRAILR was determined by immunohistochemistry and in situ hybridization in 24 samples of craniopharyngioma and 16 samples of normal brain tissue.Results With low decoy receptor(DcR) expression in partial craniopharyngioma cells and low death receptor(DR) expression in partial normal brain cells,DR was expressed highly in all craniopharyngioma samples while DcR in most normal brain tissue. High DR expression and low DcR expression in craniopharyngioma tissue differed from low DR expression and high DcR expression in normal brain tissue(P

OBJECTIVETo investigate the relationship between genetic polymorphism of X-ray repair cross-complementing gene 3 (XRCC3) and susceptibility to lead poisoning in male lead-exposed workers.

METHODSPeripheral venous blood and morning urine samples were collected from 326 male lead-exposed workers in a storage battery factory in Fuzhou. Blood lead, urine lead, blood zinc protoporphyrin (ZPP), blood calcium, and blood iron were measured. The genotype of XRCC3 was determined by polymerase chain reaction-restriction fragment length polymorphism method. The relationship between XRCC3 gene polymorphism and susceptibility to lead poisoning in male lead-exposed workers was analyzed.

RESULTSGenetic polymorphism of XRCC3 was seen in the 326 subjects. The frequency distribution of XRCC3 genotypes, XRCC3-241CC (wild type), XRCC3-241CT (heterozygous mutation), and XRCC3-241TT (homozygous mutation), was in accordance with the Hardy-Weinberg equilibrium (P > 0.05). There were no significant differences in urine lead, blood ZPP, blood calcium, and blood iron between the lead-exposed workers with different XRCC3 genotypes (P > 0.05). The workers with XRCC3-241CT/TT had a significantly higher mean blood lead level than those with XRCC3-241CC (P < 0.05). With a blood lead level of 1.90 µmol/L as the cutoff value, the chi-square test and logistic regression analysis showed that the proportion of workers with XRCC3-241CT/TT was significantly higher than that of workers with XRCC3-241CC in the subjects with high blood leads (P < 0.05) and that the risk of high blood lead was significantly higher in the workers with XRCC3-241CT/TT than in those with XRCC3-241CC (OR = 2.34, 95%CI = 1.61 ∼ 5.13); the multivariate linear regression analysis showed that the workers with XRCC3-241CT/TT had high blood lead levels (β = 0.116, P < 0.05), the workers with smoking habit demonstrated marked lead absorption (β = 0.188, P < 0.05), good individual protection could reduce lead absorption (β = -0.247, P < 0.05), and the individuals with low serum Ca²⁺ levels had high blood lead levels (β = -0.145, P < 0.05).

CONCLUSIONWhen exposed to the same level of lead at workplace, the workers with XRCC3-241CT/TT have a significantly higher blood lead level than those with XRCC3-241CC, so the genotype of XRCC3-241CT/TT accounts for higher susceptibility to lead poisoning.
