Objective To investigate effect of first, second, and third trimester placental factors (PF) on CD4, CCR5, and CXCR4 expression in human peripheral blood lymphocytes (PBLs), and to explore their influence on human immunodeficiency virus (HIV) vertical transmission.Methods Human peripheral blood mononuclear cells (PBMCs) were treated with first, second,and third trimester PF (concentration 25%) respectively for 24 hours. The expression of CD4, CCR5,and CXCR4 in PBLs, and the percentages of CCR5+, CXCR4+,and CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes were determined with flow cytometry.Results All trimester PFs reduced CCR5 expression in PBLs. The efficiency of the first trimester PF was higher than that of the second and third trimester PF. The percentage of CCR5+ cells in peripheral blood CD4+ lymphocytes of PF groups was significantly lower than that of the control group, and the percentage of CCR5+ cells in peripheral blood CD4+ lymphocytes of the first trimester PF group was significantly lower than that of the second and third trimester group. The percentages of CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes of PF groups were significantly decreased as compared with the control group, and the percentage of CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes of the first trimester PF group was significantly lower than that of the third trimester PF group.Conclusion PF can reduce the expression of CCR5 in human PBLs and peripheral blood CD4+ lymphocytes, indicating that PF might reduce R5 virus infection via preventing HIV entry, and might play an important role in reducing R5 virus intrauterine infection.

Objective To investigate the association of single nucleotide polymorphisms(SNP)in p21and p27 genes with the risk of epithelial ovarian cancer(EOC).Methods Genotypes were analyzed by polymerase chain reaction-restrictive fragment length polymorphism(PCR-RFLP)method in 234 patients with EOC and 284 control women in China.Results (1)The frequencies of the p21 in healthy controls were 34.2%.49.6%and 16.2%,while the distribution of the C and T allele was 59.0%and 41.0%,respectively.The p21 C/C(28.2%),C/T(53.0%),T/T(18.8%)distribution in ovarian cancer patients was not significantly different from that in healthy controls(P＞0.05).There was no statistic difference in allele distribution between ovarian cancer patients and healthy controls(P＞0.05)either.The stratification analysis by tumor histological type did show that the genotype distribution in four types of ovarian cancer patients was significantly different from that in healthy controls(P=0.02).The C/C genotype was likely to reduce the risk of epithelial endometrial cancer.and the adjusted odds ratio was 0.56(95%CI:0.32-0.98).(2)The genotype frequencies of the p27 in healthy controls were 88.4%,10.9%and 0.7%.while the distribution of the V and G allele was 93.8%and 6.2%.respectively.The V/V(93.6%),V/G(5.1%)and G/G(1.3%)distribution in ovarian cancer patients was significantly different from that in healthy controls(P=0.04).There was no statistic difference in allele distributionbetween ovarian cancer patients and healthy controls(P＞0.05).Compared with the V/G and G/G genotypes,the V/V genotype increased the risk of EOC,the adjusted odds ratio was 1.92(95%CI:1.02-3.63).Conclusion The C/C genotype of p21 may reduce the risk of epithelial endometrial cancer,and the genotype of p27 V/V may be a potential risk factor for susceptibility to EOC.

Objective To study the effects of modified Danggui Beimu Kushen Pills on the expressions of TLR2, TLR4, TLR6, TRAF6 and MyD88 in tumor tissues on MFC gastric cancer bearing mice; To discuss relevant mechanism of action. Methods MFC gastric cancer bearing mice were employed to perform anti-tumor experiment in vivo in this study. A total of eligible 48 mice were randomly divided into model group, DDP positive control group, modified Danggui Beimu Kushen Pills high-dose and low-dose groups, modified Danggui Beimu Kushen Pills high-dose and low-dose combined with DDP groups. The treatment was conducted once a day, and lasted for 14 continuous days. After the last administration of gavage orally treatment, all mice were anaesthetized and killed by cervical dislocation method to obtain tumor tissue completely for further HE staining measure and detection of TLR2, TLR4, TLR6, TRAF6 and MyD88 in tumor tissue with the method of RT-qPCR and immunohistochemistry. Meanwhile, the tumor growth was observed and the general conditions of mice were recorded. Results The model group was rich in tumor cells; the sizes of cells were different; the volume was large; the nucleus was deeply stained and the heterotypic shape was obvious, and the small focal necrosis was seen. The number of tumor cells in each administration group was reduced; the arrangement was loose; the cell volume was significantly reduced, and the nuclear pyknosis was reduced. Cell necrosis significantly increased; the number of interstitial blood vessels decreased; collagen fibers increased, especially in modified Danggui Beimu Kushen Pills high-dose and low-dose combined with DDP groups. Compared with the model group, the expressions of TLR2, TLR4, TLR6, TRAF6 and MyD88 mRNA and protein decreased in each administration group. TLR2, TLR4, TLR6, TRAF6 and MyD88 were lighter and weakly positive expressed in modified Danggui Beimu Kushen Pillshigh-dose and low-dose combined with DDP groups, the protein changes were more obvious Compared with DDP positive control group, modified Danggui Beimu Kushen Pills high-dose and low-dose groups. Conclusion Modified Danggui Beimu Kushen Pills can down-regulate TLR2, TLR4, TLR6, TRAF6 and MyD88 expression of tumor tissue in MFC gastric cancer bearing mice at both mRNA and protein levels to play anti-tumor pharmacology action.

Allergic reactions caused by traditional Chinese medicine injections (TCMIs) become a greatest concern in the clinic application safety. The integral animal evaluation method commonly used in the preclinical evaluation for allergic reactions of TCMIs was not sensitive, specific, quick and objective in observation indexes. Therefore, more researchers have paid attention to the in vitro test method for evaluating allergic reactions induced by TCMIs. Currently, the methods for evaluating allergic reactions induced by TCMIs are mainly targeted at type I allergic reaction and anaphylactic reaction, with only a few in vitro methods for evaluating type II allergic reaction. In this paper, researchers summarized relevant literatures published about evaluation methods for allergic reactions induced by TCMIs in recent years.
