Objective:To observe the effect on ovarian cancer immunotherapy by dendritic cells (DC) which activated by Epithelial cell adhesion molecule (EpCAM) induce antigen-specific CD8+ cytotoxic T lymphocytes (CTL) and to provide some help to ovarian cancer immunotherapy.Methods: Interleukin (IL)-12,and IL-10 of DC were tested after inducing by EpCAM.Subsequently,EpCAM specific CTL CD8+ was induced by EpCAM-DC.The therapeutic effect and interferon (IFN)-γ of EpCAM-DC-CD8+ CTL on normal ovarian epithelial cells IOSE80 and ovarian cancer cell SKVO3 was detected.After treatment of EpCAM-DC-CD8+ CTL,the volume of ovarian tumor of bearing BALB/c-nu/nu mice was detected.Meanwhile,the morphology changes of tumor tissue were observed by HE staining.Results: Compared with PBS,EpCAM stimulation significantly inceased surface markers DC80,DC83,DC86 and HLA-DR levels,and added up to 4.79,4.85,4.60 and 10.91 times (P<0.05).EpCAM stimulation significantly increased the expression of IL-12 and reduced the secretion of IL-10 (P<0.05).Both of DC-CD8+ CTL and EpCAM-DC-CD8+ CTL resulted in minute amount of IOSE80 cell killing (P>0.05).However,the killing rate of EpCAM-DC-CD8+ CTL on SKVO3 cells was 6.82-folds as much as that of DC-CD8+ CTL.Animal experiments showed that ovarian cancer transplantation tumor volume ratio after EpCAM-DC-CD8+ CTL treatment,was significantly lower than PBS group and DC-CD8+ CTL group,which reached 0.27 and 0.28 times,respectively (P<0.05).HE staining showed that EpCAM-DC-CD8+ CTL treatment resulted in significant changes of tumor tissues in pathology.Conclusion: EpCAM protein stimulated the maturation of DC that induced the production of EpCAM specific CD8+ CTL.EpCAM-DC-CD8+ CTL can effectively kill ovarian tumor cells and delay the growth of tumor,which is of great significance for the immunotherapy of ovarian cancer.

Inflammatory bowel disease (IBD) is a chronic non ‑ specific intestinal inflammatory disease. Spondyloarthritis (SpA) is a chronic inflammatory disease that occurs in the axial skeleton and surrounding joints, and is one of the most common extraintestinal manifestations of IBD. The main pathophysiologic mechanism of IBD accompanied with SpA involves the "gut‑joint axis" hypothesis, and dysbiosis of gut flora plays a key role in explaining the pathologic connection of the "gut‑joint axis" in patients with IBD accompanied with SpA. This article reviewed the progress of research on gut flora and IBD accompanied with SpA.

Objective:To explore the intervention effects of an Internet-based blood pressure monitoring and management platform in a prehypertensive population.Methods:One hundred and fifty-eight prehypertensive patients who were examined at the Third Xiangya Hospital in Changsha, China, from August to December 2019 were randomly divided into either the experimental or control groups using the random number table method. The experimental group utilized an Internet-based blood pressure monitoring and management platform, whereas the control group utilized regular telephone and SMS health management routines. The intervention duration was 12 months for both groups. Data were analyzed using descriptive analysis, t-tests, chi-square tests, χ 2 tests, and rank-sum tests. Results:Post intervention systolic blood pressure (124.79±9.71 mmHg) (1 mmHg=0.133 kPa) and diastolic blood pressure measurements (77.41±8.21 mmHg) of the participants in the experimental group were significantly lower than those before the intervention (128.29±5.10 mmHg and 79.99±6.01 mmHg, respectively), and significantly lower than those of the control group′s measurements after the intervention (130.00±7.78 mmHg and 80.33±7.90 mmHg, respectively) (all P<0.05). The blood pressure goal attainment rate was significantly higher in the experimental group (23.08%) than that of the control group (8.75%), with statistically significant differences within the experimental group before and after intervention, as well as between the groups post intervention ( P<0.05). Positive lifestyle changes, such as prehypertension knowledge score, active restriction and control of salt and oil intake, reduction of smoking, and exercising weekly, were significantly higher than those in the control group before the intervention (all P<0.05). Conclusion:The use of an Internet-based blood pressure monitoring and management platform can effectively help patients with prehypertension control their blood pressure levels, improve their knowledge about the condition, and improve their lifestyle choices.

Objective: To study the regulatory effects and possible mechanism of long non-coding RNA plasmacytoma variant translocation 1 (lncRNA PVT1) on chemotherapy sensitivity to cisplatin (DDP) of colorectal cancer (CRC)．Methods: A total of 112 pairs of matched cancer and adjacent non-cancerous tissues were obtained from the CRC patients who underwent surgical resection in the First Affiliated Hospital of Xinxiang Medical University betweenApril 2006 and March 2011.All specimens were confirmed by pathological examinations. Tumor tissues and corresponding adjacent non-cancerous tissues from 30 cisplatin-sensitive CRC patients and 30 cisplatin-resistant patients were selected. Human CRC cell lines (HT29, SW480, HCT116, RKO and LoVo) and normal colonic epithelial cell line NCM460 were also collected for this study; and DDP-resistant RKO/DDP and LoVo/DDP cell lines were constructed. siPVT1, siNC, LV-PVT1 and LV-NC were transfected into LoVo and RKO cells or LoVo/DDP and RKO/DDP cells using lipofectamineTM2000. The expression of lncRNA PVT1 in CRC tissues and cells was tested by Real-time qPCR. CCK-8 assay, flow cytometry and WB were performed to test the effect of PTV1 knockout or enforcement on cell proliferation, apoptosis and expressions of apoptosis-related proteins, respectively. The CRC subcutaneous transplanted xenograft model was established on athymic nude mice to study the effect of PVT1 over-expression on tumor growth and DDP resistance. Results: PVT1 was highly expressed in the cancer tissues and CRC cells, and its expression was positively associated with cisplatin resistance of CRC. After knockdown of PVT1, the proliferation of cisplatinresistant CRC cells was significantly suppressed, while the apoptosis was significantly enhanced (P<0.05 or P<0.01); Mechanically, the levels of drug resistance-associated molecules, including MDR1 and MRP1, as well as the expression of anti-apoptotic Bcl-2 were significantly downregulated whereas the levels of pro-apoptotic Bax and cleaved caspase-3 were increased in PVT1-silenced DDP-resistant CRC cells. Over-expression of PVT1 reversely increased proliferation and decreased apoptosis of CRC cells (P<0.05 or P<0.01). In addition, PVT1 over-expression in CRC cells significantly promoted DDP-resistance in vivo (P<0.05). Conclusion: Collectively, knockdown of PVT1 expression can significantly suppress cell proliferation and promote apoptosis of DDP-resistant CRC cells. Overexpression of PVT1 can significantly promote the growth of CRC cells in vitro and transplanted xenograft in vivo. PVT1 regulates endogenous apoptosis pathways and further promotes the sensitivity of CRC cells to cisplatin chemotherapy via inhibiting the expressions of MDR1 and MRP1.

OBJECTIVETo analyze the association of micoRNA-related genes DROSHA single nucleotide polymorphisms (SNP) rs10719 and rs6877842, DICER1 rs3742330and GEMIN4 rs3744741 with prognosis of T-cell lymphoma.

METHODSPolymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to determine the genotypes of the above 4SNPs and their associations with complete remission (CR) rate and overall survival (OS) in 163 patients with TCL.

RESULTSPatients carrying the rs6877842 CG genotype had a significantly higher CR rate compared with those carrying the CC genotype (OR=0.07, 95% CI 0.01-0.72, P=0.026); the same for patients carrying the DICER1 rs3742330 GG genotype compared with those carrying the GA genotype (OR=0.15, 95% CI 0.02-0.97, P=0.047) or the AA genotype (OR=0.11, 95% CI 0.02-0.71, P=0.020). In addition, patients with the DICER1 rs3742330 GG genotype had a significantly improved OS compared with those carrying the GA (HR=9.02, 95% CI 1.22-66.92, P=0.031) or AA genotype (HR=8.77, 95% CI 1.19-64.67, P=0.033). The other two SNPs of rs10719 and rs3744741 had no significant association with CR or OS.

CONCLUSIONDROSHA rs6877842 and DICER1 rs3742330 were independent factors for TCL CR, and DICER1 rs3742330 was also an independent prognostic factor for TCL OS.
