This paper gives the brief account of the researches in the effection of the side- cuts in perineum carried out in two angles (45°and 25～30°) during the helps in child birth between two groups of eutosia on the similar condition:fetal weight the contradict of womb perineum tissue e. g.. The results show that amnong 116 parturients with side- cut in 45( contrated group), the rate of tearing is 62.06%; on the contrary, among 110 parturients with side - cut in 25 ～ 30°( improved group), the rate of tearing is 35.45 %. According to statistics analysis, the rate of tearing in two groups has a marked difference (P＜0.01). It directly shows the parturients in improved group have the advantages:shortening the sewing- up time lessening needling numbers reliving of the after - pains making the parturients get out bed some time later and sulkle the new- born babies in sitting way,reducing the nursing,shortening the time of infection.

The tumor microenvironment plays a vital role in the process of tumorigenesis and development.Studies have been confirmed that the tumor microenvironment heterogeneity has a huge impact on the tumor efficacy and drug resistance.This review summarizes the relationship between immune cells and related immune factors in tumor microenvironment as well as vascular endothelial cell heterogeneity and tumor progression and prognosis.So it is better help us understand the tumor microenvironment heterogeneity for the impact of the tumor.This will conduce to us through a variety of methods to enhance the body's anti-tunor ability by inhibi-ting and killing tumor cells.

OBJECTIVETo explore the molecule mechanism of Salidroside inducing directional differentiation of mouse mesenchymal stem cells (MSCs) into neuronal cells.

METHODSThe mouse multipotent mesenchymal precursor cell line (D1) was taken as the objective. Cultured MSCs were divided into the negative control group (complete culture solution), the positive control group (containing 1 mmol/L β-mercaptoethanol), the Salidroside induced group (20 mg/L Salidroside), and the blocked group (20 ng/ ml DKK1, a special inhibitor of Wnt/β-catenin signal pathway). All cells were inoculated in a 6-well plate (1 x 10(4) cells/cm2) and grouped for 24 h. The expression of p-catenin was detected by fluorescence Immunochemistry in the negative control group, the positive control group, and the Salidroside induced group. The expression of neuron-specific enolase (NSE), beta 3 class III tubulin (β-tubulin III), nuclear receptor related factor 1 (Nurr1), glial fibrillary acidic protein (GFAP) mRNA, Wnt3a, β-catenin, low-density lipoprotein receptor-related protein6 (LRP6), Axin mRNA were detected using reverse transcrip- tion PCR (RT-PCR). The expression of β-catenin and NSE protein were analyzed by Western blot in the negative control group, the positive control group, and the Salidroside induced group. Ca2+ chelating agents (EGTA), L-type Ca2+ channel blocker (Nifedpine), and IP3Ks special inhibitor (LY294002) were used to block Ca2+ signal pathway respectively. The expression of Wnt3a, LRP-6, Axin, glycogen syn- thase kinase (GSK-3), and β-catenin mRNA were detected by RT-PCR. The β-catenin protein expression was analyzed using Western blot.

RESULTSCompared with the positive control group, β-catenin protein was strong positively expressed; the expression of Wnt3a, β-catenin, LRP6, Axin, NSE, β-tubulin III, Nurr1 mRNA, and NSE protein were obviously up-regulated in the Salidroside induced group (P < 0.01). Compared with the positive control group and the Salidroside induced group, β-catenin, NSE, Nurr1, and β-tubulin III mRNA expression decreased; β-catenin and NSE protein expression were also down-regulated in the blocked group (P < 0.01). Compared with the Salidroside induced group, the expression of Wnt3a, LRP-6, β-catenin, and Axin mRNA were down-regulated in the Ca2+ signal blocked group and the salidroside induced group (P < 0.01, P < 0.05).

CONCLUSIONSalidroside affected directional differentia- tion of MSCs into neuronal cells through Wnt/β-catenin and Ca2+ signal pathway.
