OBJECTIVETo investigate the effect of Abnormal Savda Munziq (ASMq) flavonoids on proliferation, apoptosis and apoptosis-related gene expression in human hepatoma (HepG2) cells in vitro and to probe the mechanism.

METHODThe effects of ASMq flavonoids on proliferation, apoptosis and apoptosis-related gene expression of HepG2 cells were investigated respectively by MTT assay, gel electrophoresis, flow cytometry and RT-PCR.

RESULTASMq flavonoids significantly inhibited growth of HepG2 cells in vitro, arrested HepG2 in the sub-G, phase, induced cell apoptosis and significantly down-regulated expression level of Bcl-2 mRNA, and up-regulated expression of p53, p21, Bax gene mRNA expressions.

CONCLUSIONASMq flavonoids has significantly regulative action on growth, apoptosis and apoptosis-related gene expression of cancer cells in vitro, which possibly are the important way to excert anticancer effect, and flavonoids are possibly a main active component of ASMq for exerting the anticancer effect.

OBJECTIVETo investigate the association of vitamin D receptor (VDR) gene polymorphisms with urolithiasis in Uyghur children from southern Xinjiang, China, and to clarify the molecular genetic mechanism for the disease.

METHODSSeventy-four Uygur children with urolithiasis (case group) and 103 healthy Uyghur children (control group) were enrolled as subjects. Polymerase chain reaction-restriction fragment length polymorphism was used to analyze the association of VDR gene FokI and ApaI polymorphisms with urolithiasis in Uyghur children from southern Xinjiang.

RESULTSThere were significant differences in FokI genotypes (FF, Ff and ff) between the case and control groups (χ2=7.818, P<0.05). The genotype Ff accounted for 58% of all genotypes in the case group, and Ff was significantly more prevalent in the case group than in the control group (P<0.05). There were no significant differences in ApaI genotypes (AA, Aa, and aa) between the case and control groups.

CONCLUSIONSThe polymorphisms of VDR gene FokI may be a suitable genetic marker for urolithiasis in Uyghur children.

OBJECTIVETo explore the relationship between the asthmatic Uyghur patients with abnormal Savda in Xinjiang and the gene polymorphism of interleukin-4 (IL-4).

METHODSTotally 76 asthmatic patients were syndrome typed according to the body fluid theory of Uyghur medicine. Among them, there were 30 asthmatic patients with abnormal Savda and 46 asthmatic patients without abnormal Savda. A comparison study was performed in 89 healthy individuals (as the healthy control group). The gene polymorphism of IL-4 promoter area-589 (C/T) site were detected by using PCR-RFLP.

RESULTSThe distribution rate of genotype CT in asthmatic patients with abnormal Savda was significantly higher than that of the asthmatic patients with non-abnormal Savda and the healthy control group (P < 0.01). The distribution rate of genotype CT in asthmatic patients with non-abnormal Savda group was significantly higher than that of the healthy control group (P < 0.05). There was no difference in the distribution frequency of genotype CC or TT, or in the distribution frequency of allele C and T among the three groups (P > 0.05).

CONCLUSIONAsthma in Uyghur patients with abnormal Savda in Xinjiang might be correlated to the gene polymorphism of IL-4 promoter area-589 (C/T).
