Objective To investigate the biological effects of Wnt gene in kidney cancer Caki?2 cells. Methods The Wnt gene was silenced in kidney cancer Caki?2 cells by lentivirus vector. The cell proliferate ability of cells in each group were assayed by CCK?8 kit at different time points. The apoptosis of Caki?2 cells was observed after silencing Wnt gene by transmission electron microscope. The invasion ability of each group cells was tested using Transwell chambers. The genes expression changes of Wnt/β?catenin signaling pathway and apoptosis related gene were determined by realtime PCR. Results Compared with the other two groups,the cell proliferate ability of the cells after silencing Wntgene was suppressed,and the difference was statistically significant(P<0.05). Apoptosis increased significantly in shRNA+Caki?2+Wnt group cells with silencing of Wntgene, and apoptotic body appeared in these cells. In invasive experiment,the number of emigrated cells in shRNA+Caki?2+Wnt group were significantly lower than other groups(P<0.05). The expression of Wnt mRNA,β?catenin mRNA and Bcl?2 mRNA in shRNA+Caki?2+Wnt group cells was lower than other groups(P<0.05). Conclusion Silencing of Wnt gene of kidney cancer Caki?2 cells can affect the proliferation rate of the cells, promote the cell apoptosis,and inhibit the invasion ability,which provide certain theoretical basis for the research and development of new drugs and new therapeutic targets.

Objective To investigate the association of the LIPC-C480T (rs1800588) and lipid levels and dyslipidemia in different age-and-sex groups in Han Chinese population.Methods The serum TC,TG,LDL-C and HDL-C were detected by automatic biochemical analyzer in 2420 health adults (1527 men and 893 women).The genotypes of rs1800588 were detected by M ALDI-TOF MS.According to the age difference (≤44,45-59 and ≥60-year-old),the total samples were divided to young (241 men and 201 women),middle-aged (652 men and 360 women) and older (634 men and 332 women) groups.The effects of genotypes on 4 serum lipid indicators in each age-and-gender group were analyzed by one way analysis of variance (ANOVA),and the odd risk of genotypes on dyslipidemia was estimated by binary Logistic regression analysis.The P value less than 0.05 was considered statistically significant.Results The frequence of allele T for LIPC rs1800588 in this population is 39.4％.In each age group the lipid parameters are quite different between males and females.Compared with those with CC genotype,middle-aged and elder men with CT or TT genotype have higher TC and HDL-C levels,and elder men with TT genotype also have higher TC level ; young women bearing CT genotype have higher TC level,and the CT and TT genotypes have higher HDL-C levels,middle aged women with CT or TT genotype have higher TC and TG levels,and CT genotype also have higher HDL-C level,the elder women with TT genotype have higher HDL-C level.Compared with those CC genotype individuals,the risk for mixed hyperlipidemia and hypercholesterolemia increases 2.318 folds (P =0.004) and 2.571 folds (P ＜ 0.001) respectively,while the risk for low HDL-C decreases 1.908 folds (P =0.029) for TT genotypes individuals among elder males; the hypercholesterolemia risk increasc 1.688 (P =0.036) and 2.099 times (P =0.040) in CT and TT genotypes respectively,and the risks for hypertriglyceridemia and mixed hyperlipidemia are 2.060 (P =0.038) and 2.381 (P =0.019) times higher than those with CC genotype among middle-aged females.Conclusions The LIPC rs1800588 site associates with the lipid levels and dyslipidmia risk in Han Chinese in an age-and-sex model.This SNP site has higher impact on lipid levels and dyslipidemia among elder males and middle-aged females,and the T allele is the risk factor.

Objective To study the predictive effect of model ［GM(1,1)］ in China’s maternal and child health indicators, and to predict the future maternal and child health indicators in a short-term, and provide a scientific basis for the gradual improvement of maternal and child health care services in China. Methods The maternal mortality rate (MMR), neonatal mortality rate (NMR), infant mortality rate (IMR) and under-five mortality rate (U5MR) were collected from 2008 to 2017 in China. Models were established and MATLAB 2018b software was used for predictive analysis. Results The prediction models of maternal mortality rate, neonatal mortality rate, infant mortality rate and under-five mortality rate were as follows: x^(k+1)=-476.08e-0.09k+510.28(C1=0.165,P1=1.000)，x^(k+1)=-108.43e-0.09k+118.63(C2=0.043,P2=1.000)，x^(k+1)=-160.60e-0.09k+175.50(C3=0.085,P3=1.000),x^(k+1)=-224.37e-0.08k+242.87(C4=0.124,P4= 1.000)，the average relative errors were as follows: 3.46%,0.67%,1.75% and 2.36%。 Conclusions The GM (1,1) is suitable for the prediction of maternal and child health indicators in China, and the fitting accuracy is high. It is predicted that the indicators will continue to decline year by year in the next three years, and relevant departments should strengthen the management work in a targeted manner.

Objective:To observe the effects of preventative moxibustion on analgesia,substance P(SP),prostaglandin(PG)F2α and PGE2 in rats with dysmenorrhea due to cold-dampness stagnation,and to explore the analgesic mechanism. Methods:Sixty-four female Wistar non-pregnant rats were randomly divided into a blank group,a model group,a Western medicine group,and a preventative moxibustion group,with 16 rats in each group.Eight qualified diestrus rats were selected from each group.Except for the blank group,the other three groups established models of dysmenorrhea due to cold-dampness stagnation using an ice water bath combined with estradiol benzoate and oxytocin.On the 8th day after modeling,the preventative moxibustion group was treated with gentle moxibustion at Shenque(CV8)and Guanyuan(CV4),and the Western medicine group was given ibuprofen solution for 4 consecutive days.On the 11th day,the intervention groups(i.e.the Western medicine group and the preventative moxibustion group)were treated once again after being injected with oxytocin.The writhing score and the pain threshold of rats were determined;the serum levels of brain-derived neurotrophic factor(BDNF),SP,PGF2α,and PGE2 were measured;the mRNA and protein expression levels of BDNF and its receptor tropomyosin receptor kinase B(TrkB)in the spinal dorsal horn and hypothalamus were detected. Results:Compared with the blank group,the writhing score increased(P<0.01),the pain threshold decreased(P<0.01),the serum levels of BDNF,SP,and PGF2α increased(P<0.01),while the PGE2 decreased(P<0.01);the protein and mRNA expression levels of BDNF and TrkB in the spinal dorsal horn and hypothalamus increased(P<0.01)in the model group.Compared with the model group,the writhing score decreased,the pain threshold increased,the serum BDNF,SP,and PGF2α levels decreased significantly,the serum PGE2 level increased,and the protein and mRNA expression levels of BDNF and TrkB in the spinal dorsal horn and hypothalamus decreased significantly in the preventative moxibustion group and the Western medicine group,while the inter-group differences were significant(P<0.01).Compared with the Western medicine group,the writhing score decreased,the pain threshold increased,the serum BDNF,SP,and PGF2α,levels decreased,the serum PGE2 level increased,and the protein and mRNA expression levels of BDNF and TrkB in the spinal dorsal horn and hypothalamus in the preventative moxibustion group decreased significantly,while the inter-group differences were significant(P<0.05 or P<0.01). Conclusion:Preventative moxibustion at Shenque(CV8)and Guanyuan(CV4)can improve the pain sensitization state of rats with dysmenorrhea due to cold-dampness stagnation,down-regulate the mRNA and protein expression levels of BDNF and TrkB in the spinal dorsal horn and hypothalamus;regulation of the serum SP,PGF2α,and PGE2 levels may be part of the mechanism.

OBJECTIVETo study the immuno-tolerance mechanism of the third-party bone marrow-derived mesenchymal stem cells (BMSCs) in the allogeneic transplantation.

METHODSForty female C57BL/6 mice and forty male BALB/C mice were respectively used as donors and recipients in skin allogenic graft model. Forty male BALB/C mice were divided randomly into 4 groups: blank control group, CP group, BMSCs group , CP + BMSCs group, with 10 mice in each group. Before skin graft, high-dose abdominal injection of cyclophosphamide (200 mg/kg, 2 d, q. d.) was performed in recipient mice in CP and CP + BMSCs groups. On the transplantation day, a bonus of 2 x 10(6) BMSCs from the SD rat (SD-BMSCs) were injected through the tail vein in the BMSCs and CP + BMSCs groups. The observation and HE staining of skin grafts were used. The expressions of CD29, CD34, CD45 and CD90 of cells were analyzed by using flow cytometry in order to identify BMSCs. The CD4+, CD25+, Foxp3 and Treg cells of spleen were detected by flow cytometry. Cytokine in peripheral blood of recipient mice were measured by ELISA, including TGF-beta, IL-10 and IFN-gamma. T cells were co-cultured with 60Co-irradiated bone marrow MSCs from different individuals. The proliferative activity of T cells were evaluated with MTT assay.

RESULTSThe skin graft survival time was significantly prolonged in the CP + BMSCs group, as compared with that in the blank control group, the CP group, the BMSCs group, respectively. Cells cultured by whole bone marrow adherent cultivation showed CD29 (99.7%), CD44+ (96.7%), CD34- (1.6%), CD45- (1.3%). Compared with the control group and CP group, the ratio of the CD4+, CD25+, Foxp3+ and Treg cells significantly increased in the SD-BMSCs group and CP + BMSCs group (P < 0.05). Analysis of peripheral blood by ELISA showed significant high level of TGF-beta, IL-10 and low level of IFN-gamma in BMSCs group and CP group,compared with that in control group. When co-cultured with BMSCs from different individuals, T- lymphocytes proliferation decreased apparently in SD-BMSCs group and C57-BMSCs group (P < 0.05), but there was no significant difference between SD-BMSCs group and C57-BMSCs group (P > 0.05).

CONCLUSIONSThe immunotolerance mechanism of the third-party bone marrow-derived mesenchymal stem cells in the allogeneic transplantation might be associated with its effect on the proliferation of Treg cells and increasing expression of TGF-beta and IL-10, decreasing expression of IFN-gamma.
