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.

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.

Objective To evaluate the serum prostate specific antigen(PSA)change after I-125 radioactive seed implantation without androgen ablation therapy for prostate cancer,Methods A total of 13 patients with prostate cancer were included.The clinical stage was T_(1c)N_0M_0 in 8 cases,and T_(2a)N_0M_0 in 5. The Gleason scores were 5 in 4 cases and 6 in 9.The mean serum PSA was 8.2 ng/ml(range,2.8-14.6 ng/ml).I-125 seed implantation(D90=140-155 Gy)was performed.Serum PSA was monitored every month for the first 3 months and every 3 months for the next 20 months.Results The range of follow-up time was 3-23 months.At 1,2,3,6,9,12,15,18 and 21 months after implantation,the median serum PSA values were 6.7,5.0,2.7,1.6,1.2,0.9,0.8,0.8 and 0.7 ng/ml;and the median percentage change in ser- um PSA were 72%,51%,29%,20%,13%,11%,9%,9% and 8%,respectively.One month after brachy- therapy,30% of the patients had fluctuation in PSA.Conclusions Compared with radical prostatectomy and androgen ablation therapy,the rate of PSA decline is slower with fluctuation at early phase.The most sig- nificant decline of PSA occurs in the first 12 months,especially in the first 3 months after I-125 seed implan- tation.

Objective To compare the curative effect of high ligation+exfoliation and subfascial endoscopic perforator surgery(SEPS)for superficial varicose veins in calf+invagination spot-striping surgery in great venous varicosity.Methods Study group(42 patients)accepted SEPS+invagination spot-striping surgery and control group (42 patients)accepted traditional surgeries.Operation duration,bleeding volume in operation,the time of beginning movement away from bed after operation,hospitalization duration,the degree of pain,the scar,the recrudescence af- ter operation and the instance of the ulcer heals of two groups were compared.Results Operation duration,bleeding volume in operation,the time of begin movement away from bed after operation and hospitalization durations of study group were significantly lower than those of control group(P0.05).All of the patients in study group recovered without severe syndromes such as venous thrombosis,skin necrosis,lower limb functional disorder etc.They had no recrudesce after 4～16 months and were satisfied with the curative effect.Con- elusions The clinical curative effect of SEPS+invagination spot-striping surgery in great venous varicosity is superi- or to that of traditional operation and it has the advantages such as minor wound,few scars,light pains,short hospi- talization duration,without recrudescence,the ulcer heals quickly and so on.

Objective To observe the effects of low-intensity(650 nm,5 mW)laser irradiation on the pathological changes associated with aortic atherosclerosis using a rabbit model.Methods Thirty-six male Zelanian rabbits were randomly divided into 4 equal groups:a control group,a laser irradiation group,a simvastatin treatment group and a laser plus simvastatin group,and were treated accordingly.After being fed the basic diet for a week,all the animals were fed a high fat diet during the experiment.Blood samples were taken for lipid assay at the 60th day. The animals were sacrificed at the 61st day and their aortas removed for gross and microscopic examination.Any pathological changes were graded as mild,intermediate or severe according to the indicators of atherosclerosis observed.Results There were no significant differences in blood fat levels among the four groups before the experi- ment,but significant differences in serum triglyceride prevailed after the treatments.Low-density lipoprotein(LDL)- C level in the control group was significantly higher than those in the laser irradiation,simvastatin treatment and laser plus simvastatin groups.There was also a very significant difference in high-density lipoprotein(HDL)-C levels among the laser irradiation group,the laser plus simvastatin group and the control group.The pathological changes observed were correlated with blood fat levels.Mild atherosclerosis was found in the treated groups,but severe or in- termediate atherosclerosis was more prevalent in the control group.Conclusion Low-intensity laser irradiation a- lone or combined with simvastatin can significantly decrease blood lipid levels and the severity of pathological changes associated with aortic atherosclerosis in this animal model.
