目的探讨HLA-G非编码区单核苷酸多态性在复发性流产患者中的表达及对影响多因素Logistic分析研究。方法选择2016年6月-2018年12月我院正常妊娠且无流产史患者作为对照组,选择期间复发性流产患者(URSA)作为观察组其中对照组30例,观察组20例。采用聚合酶链反应(PCR)检测HLA-G非编码区14bp基因多态性和逆转录-聚合酶链反应(RT-PCR),比较两组人群绒毛组织HLA-G 14bp插入/缺失基因型及绒毛组织中HLA-G mRNA的相对表达量及对多因素Logistic分析的影响。结果观察组-14bp/+14bp的杂合子基因频率为65.00%,对照组-14bp/+14bp的杂合子基因频率为43.33%,观察组高于对照组,差异有统计学意义(P<0.05);插入纯合子基因频率为+14bp/+14bp为10%。对照组基因频率为26.67%,与对照组比较有统计学意义(P<0.05);观察组HLA-G mRNA水平显着高于对照组(t=9.658,P=0.000)(P<0.05);HLA-G 蛋白在观察组里呈强表达,在对照组里呈弱表达,差异有统计学意义(P<0.05);HLA-G非编码区单核苷酸多态性也是导致患者复发性流产的一个重要因素,对于复发性流产多因素Logistic分析研究提供一个新的研究方向。结论 HLA-G非编码区-14bp/+14bp的杂合子基因大大增加了复发性流产患者的发病几率,同时复发性流产影响HLA-G mRNA及HLA-G 蛋白的正常表达。对复发性流产多因素Logistic分析提供一个新的研究方向。     

A Study on Isolation of Chemical Constituents from Sophora Flavescens Ait. and Their Anti-Glioma Effects

Background

Sophora flavescens Ait. is a traditional Chinese medicine with a long history in China. It is mainly used in the treatment of heat dysentery and similar ailments in the clinical. The objective of this paper was to isolate, purify and identify alkaloids from Sophora flavescens Ait. and to explore their inhibitory effects on C6 glioma cells.

Materials and Methods

Column chromatography, extraction and NMR spectroscopy were used to structurally identify the isolated compounds. MTT assay and flow cytometry were used to detect the inhibitory effect of matrine on C6 cells.

Results

Three compounds were isolated from Sophora flavescens Ait., namely matrine, oxymatrine and lupeol. Different concentrations of matrine solution all had inhibitory effects on growth of C6 cell lines, which showed apparent dose-effect relationship. Compared with the control group, proportion of G0/G1 phase cells increased in each matrine concentration group to a maximum of 79.8%; proportion of S phase cells reduced, and proportion of G2/M phase cells declined slightly to a minimum of 6.3%, suggesting that after the action of matrine proliferation of C6 cells was significantly inhibited and the cells were arrested in the G1 phase.

Conclusion

We concluded that Sophora flavescens Ait. has an inhibitory effect on C6 cell proliferation.

The adsorption of 99mTc(Sn)—diphosphonate complexes on tri-calciumphosphate: the influence of preparation conditions,ligand-type,incubation media and adsorption conditions. The reversibility of the adsorption

The influence of several variables on the adsorption of ^99mTc(Sn)—diphosphonate complexes on tri-calciumphosphate was determined. The composition of the incubation medium influenced the percentage adsorption: with Hank's balanced salt solution (a medium frequently used for bone cell cultures) and Tris buffer lower percentage adsorption was obtained than with physiological saline as the incubation medium. The influence of addition to the incubation medium of some ions and neutral species, some of which occur in bone fluid, is very specific. Addition of Sn(II) or Mg(II) (a component of HBSS) reduces the amount of adsorption. Addition of Ca(II) and Al(III) had no effect. Addition of sodium—citrate and MDP to the medium and an increase of the pH of the medium decreased the percentage adsorption. The ligand that was used in the preparation of the complex mixture influences the percentage adsorption considerably. The Sn(II) concentration used during the preparation of the ^99mTc(Sn)—MDP and ^99mTc(Sn)—MHDP complexes showed no definite influence on the percentage adsorption. The pH and ligand concentration, used in the preparation, however, did effect the percentage adsorption. It was concluded that the ^99mTc(Sn)—disphosphonate mixtures are part reversibly and part irreversibly bound to tri-calcium-phosphate.
