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.

Objective To investigate the distribution of ghitathione-S-transferase M1 (GSTM1) and T1 (GSTT1) genes polymorphisms in Chinese population and smear-positive pulmonary tuberculosis cases of Jilin province. Methods Articles about GSTM1 and GSTT1 genes polymorphisms published before 2009 in China were searched. The study population was obtained from fourteen counties (or districts) of Jilin province, which included all cases from November, 2007 to May, 2008, totally 1120. The genotypes of GSTM1 and GSTT1 were detected by multiplex PCR technique. Results The frequencies of GSTM1 and GSTT1 'null' genotypes and combination M1-T1 'null' genotype acquired from systematic review were 54.2%, 46.8% and 26.2%, respectively, in Chinese Hans they were 53.4%, 44.9% and 25.5%, and in our research they are 57.2%, 20.4% and 13.7%, respectively. No significant differences between the frequencies of males and females as well as among that of different age groups were observed(P>0.05). The frequency of GSTM1 'null' genotype in our research is slightly higher than that in systematic review (P=0.016) , and the frequencies of GSTT1 'null' genotype and combination M1-T1 'null' genotype and are significantly lower than those in systematic review (both P<0.001). Conclusion The frequencies of GSTM1 and GSTTI 'null' genotypes were different among ethnics. The statistical difference between systematic review and our research may due to our large sample size and mostly Soutbern people in previous studies.

OBJECTIVETo investigate the AvaII polymorphism of low density lipoprotein receptor gene in both health and essential hypertension populations, and to evaluate the association of AvaII polymorphism with level of blood lipid.
METHODSUsing polymerase chain reaction (PCR), AvaII polymorphism was studied in 109 health individuals and 319 patients with essential hypertension.
RESULTSThere were three kinds of genotype: (+/+), (+/-), (-/-). The frequencies of the three genotypes were shown as follows: (+/+) 0.9%, (+/-) 27.5%, (-/-) 71.6% in health population and (+/+) 1.2%, (+/-) 33.9%, (-/-) 64.9% in essential hypertension population, respectively. The frequencies of the two alleles were shown as follows: (+) 14.7%, (-) 85.3% in health population, (+) 18.2%, (-) 81.8% in essential hypertension population and (+) 17.3%, (-) 82.7% in the community, respectively. In male essential hypertension cases, the genotypes were associated with serum TC and LDL-C level in the following order: (-/-) < (+/-) (P < 0.05). In women and healthy population, there was a similar trend but not statistically significant (P > 0.05).
CONCLUSIONSA significant association was found between the common variation of LDL-R gene and serum TC and LDL-C levels. (+) Allele was associated with elevated level of serum TC and LDL-C, but (-) allele was associated with a low level of serum TC and LDL-C. The frequencies of (-) allele in both group were related to serum low level TC while LDL-C was much higher than that reported in the western countries. These data indicated that genetic factors which resistant to hypercholesterolemia in Chinese people were different from those findings in West while might be one of the reasons to explain why that serum TC level in Chinese was lower than people in the western countries.

BACKGROUNDRecent studies have identified signal transducer and activator of transcription 4 (STAT4) as a susceptibility gene for systemic lupus erythematosus (SLE) in different populations. In order to examine whether the allele distribution of the single nucleotide polymorphism (SNP) in gene STAT4 rs7574865 in patients with SLE is different from those of healthy controls in Chinese Northern Han population, we investigated whether the variants of STAT4 rs7574865 were associated with any specific clinical features of SLE.
METHODSWe genotyped SNPs in STAT4 rs7574865 in 252 patients with SLE and 497 healthy controls. All subjects were from the Northern part of Chinese Han population. The genotypes in rs7574865 were determined by polymerase chain reaction (PCR) and consequence direct sequencing of PCR products in the DNA samples.
RESULTSThere was a significant difference in distribution of the SNPs in rs7574865 between the SLE patients and healthy controls. Compared with healthy controls, there was a significant correlation between TT genotypes in rs7574865 and the risk of SLE when GG genotype was used as a reference genotype after adjusting for gender and age. The frequency of T allele in the SLE patients was strongly significantly higher than that of healthy controls. Furthermore, there was a significant difference in the distribution of SNP in rs7574865 between male and female SLE patients, when compared with healthy controls. The frequency of T allele in rs7574865 in male patients was significantly higher than that of male healthy controls or female patients. There was no significant correlation between the frequencies of T allele in STAT4 rs7574865 and the clinical features of SLE.
CONCLUSIONSThe SNP rs7574865 in STAT4 is strongly associated with risk of SLE in the Chinese Northern Han population. The TT genotype and T allele in STAT4 rs7574869 are susceptibility factors for SLE, especially for male SLE patients.
