Objective To investigate the role and clinical significance of RANTES in endometriosis (EM). Methods The serum level of RANTES was examined by ELISA in 50 patients with endometriosis (EM group), 32 patients with benign ovarian neoplasms (disease control group) and 30 normal control women (normal control group). The level of RANTES in peritoneal fluid was examined in EM group and disease control group. Results The serum level of RANTES was significantly higher in EM group (108.73±60.69) ng/L than that of disease control group (31.26±20.33) ng/L and normal control group (29.77 ± 11.58) ng/L (P＜0.05). The level of RANTES in peritoneal fluid was significantly higher in EM group (726.31 ± 259.83) ng/L than that of disease control group (116.19 ± 81.64) ng/L (P＜0.05). The levels of RANTES in serum and peritoneal fluid in EM group were positively correlated with clinical stage respectively (rs=0.501 and 0.562,P＜0.01). The level of RANTES in peritoneal fluid in EM group was positively correlated with dysmenorrhea score (rs=0.527,P＜0.01). The serum level of RANTES was positively correlated with the level of RANTES in peritoneal fluid in EM group (rs=0.363, P＜0.05). The levels of RANTES in serum and peritoneal fluid were positively correlated with inflammatory response degree in endometriotic tissues in EM group (rs=0.326 and 0.391,P＜0.05 or P＜0.01).Conclusion Detection of the serum level of RANTES by ELISA may be one of parameters for diagnosis of endometriosis.

In order to investigate the molecular evolution and spatio-temporal migration of Getah viruses (GETV) isolated around the world,the nucleotide and deduced amino acid sequence of GETVs were analyzed and phylogenetic trees were constructed by using informatics software including ClustalX1.83,MegaAlign,GeneDOC and Mega6.0.The Bayesian Stochastic Search Variable Selection (BSSVS) program in the BEAST v 1.8.1 software package was used to analyze the spatial dynamics of the Getah virus.Results showed that the full-length of Getah virus E2 gene consists of 1 266 nueleotides,encoding 422 amino acids.And the homology of nucleotide and amino acid were 94.5％ 100％ and 96.4％ 100％ respectively.The molecular evolution analysis revealed that there were no species and geographical distribution difference existing among GETV host animals (e.g.horses and pigs) and vectors (e.g.mosquitoes).Bioinformatics analysis showed that GETV originated in Malaysia,then it was spread to Japan,China,South Korea,Mongolia,Russia,etc.GETV E2 gene was relatively stable since GETV was first isolated in 1955.The differences of species and geographical distribution did not exist among GETV host animals and vectors,and the virus has spread from tropical regions to Eurasian continent.Thus,strengthening the detection and monitoring of GETV and its infections in humans and livestock is critical.

Objective: To evaluate the anti-tumor activity of mouse multi-subtype heat shock protein/peptide (mHSP/P) vaccine in combination with a programmed death ligand 1 (PD-L1) inhibitor in mouse sarcoma. Methods: Immunohistochemical staining and en-zyme-linked immunosorbent assay (Elisa) was used to quantitatively identify the expression of heat shock proteins (HSP70, HSP90, Grp94) in the sarcoma cell line MCA207. From the protein suspension prepared, mHSP/P and Grp94/peptide (Grp94/P) sarcoma vac-cines were isolated using chromatography and were identified by Western blot (WB). Flow cytometry was used to determine their cy-totoxic effects. The levels of interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) produced upon mHSP/P and Grp94/P stimulation were measured by Elisa. The effect of sarcoma vaccines on the growth and survival of sarcoma was evaluated in mice. The expression of PD-L1 on the surface of MCA207 sarcoma cells was evaluated by immunofluorescent staining. The effect of IFN-γ treatment on the expression of PD-L1 was determined by WB. Animal experiments explored the effects of PD-L1 inhibitor in combination with mHSP/P treatment on tumors. Results: Tumor tissue carries a variety of HSP subtypes (HSP70, HSP90, Grp94). We successfully isolated sarco-ma tissue-derived mHSP/P and Grp94/P tumor vaccines, which were identified by WB; flow cytometry analysis demonstrated their cy-totoxicity. The levels of IFN-γ and TNF-α cytokines upon mHSP/P stimulation were significantly higher than that observed upon Grp94/P stimulation (P<0.05). The expression of PD-L1 on the surface of sarcoma cells increased with IFN-γ treatment. Animal experiments demonstrated that PD-L1 inhibitor in combination with mHSP/P significantly increased the immune response against tumor (P<0.05). Conclusions: Tumor-derived mHSP/P and Grp94/P can be used as tumor vaccines in animal models. The mHSP/P can elicit a stronger anti-tumor immune response than Grp94/P. IFN-γ stimulates the expression of PD-L1 in sarcoma cells, which results in immune eva-sion. The PD-L1 inhibitor in combination with mHSP/P increased the anti-tumor effect in the tumor microenvironment.
