Objective To investigate the elinicopathologic features of atypical endometriosis(AEM) and to discuss the relationship between AEM and tumors. Methods A retrospective analysis was performed of 163 cases of AEM, which were retrieved from the Department of Pathology files at the Tianjin Central Obstetrics and Gynecology Hospital between Jan 2004 and Dec 2006. The pathologic changes of AEM including its glandular epithelium, stroma, background and the conditions coexisting with tumor were observed. Results The AEM accounted for 4.38% (163/3724) of the endometriosis (EM) eases. Of 172 AEM foei of 163 patients, 168 were in the ovary, and the other 4 were in the fallopian tube, cervix and uterine serosa respectively. The rate of ovarian AEM was 6.81% of endometriosis. AEM associated with tumour was found in 26 cases (15.95% )and among 27 of ovarian AEM, 15 were malignant, 9 borderline and 3 benign. The AEM epithelia were mainly arranged in the form of surface epithelium. They present with characteristic features of moderate to marked pleomorphism, epithelial tufting and bud structures by microscopy. The walls of AEM cyst were presented with three layers of epithelium, endometrioid stroma and fibrosis-collngen. The endometrioid stroma were usually thin in contrast to the fibre-collagen tissue, which was often thick with scarred background. The transformation from AEM to tumor was found in most of the malignant tumors( 14/15,93% ). Conclusions AEM lesions hold some features of both EM and tumor, which may have a relatively higher potential for tumorigenesis and cancerafion. The process of damage and repair in EM foci during a long course may play a role in the development of EM into AEM and finally into tumor.

BACKGROUND:Existing evidence has confirmed that umbilical cord blood mesenchymal stem cel s have an effect on functional recovery of a variety of damaged cel s.
OBJECTIVE:To explore the effect of umbilical cord blood mesenchymal stem cel transplantation on ovarian cancer chemotherapy.
METHODS:Sixty healthy adult female Wistar rats were randomly divided into normal control group, damage group and treatment group (n=20/group). There was no treatment in the control group, and a rat model of ovarian cancer chemotherapy damage was made in the damage group and treatment group. After successful modeling, rats in the control group were given normal saline injection via the tail vein, and those in the damage and treatment groups were given paclitaxel chemotherapy and pacligaxel chemotherapy plus umbilical cord blood mesenchymal stem cel transplantation, respectively. After transplantation of 2 weeks, mRNA and protein expressions of XAF1 and Survivin in ovarian tumor tissues were detected by RT-PCR and western blot assay, respectively. Apoptosis in ovarian cancer cel s were detected using TUNEL method.
RESULTS AND CONCLUSION:Compared with the damage group, a significant up-regulation of XAF1 mRNA and protein but a remarkable down-regulation of Survivin mRNA and protein were obtained in the treatment group (P<0.05). A severe damage to the ovarian tissues was visible in the damage group, presenting with large hemorrhage and necrosis area. This damage was markedly reduced in the treatment group. Additional y, the apoptotic rate of ovarian cancer cel s was significantly higher in the treatment group than the damage group (P<0.05). Al these findings indicate that umbilical cord blood mesenchymal stem cel transplantation aids in ovarian cancer chemotherapy to promote ovarian tissue repair in rats, and XAF1 and Survivin cannot be ignored in tumor angiogenesis and ovarian cancer cel apoptosis.

ObjectiveTo investigate the relationship of the polymorphism of endothelial nitric oxide synthase (eNOS), the 27-bp variable number of tandem repeats (VNTR) in intron 4 with essential hypertension (EH) of the northern Han nationality in China.MethodsGenotypes, the level of plasma nitric oxide metabolites (NOx) and the activity of nitric oxide synthase (NOS) of 207 EH subjects and 231 healthy subjects were measured by polymerase chain-reaction (PCR).ResultsThe frequencies of ecNOS4a/a,ecNOS4b/a, and ecNOS4 b/b in the healthy group were 0.43%, 13.42% and 86.15% respectively. The frequency of the b allele was 92.86%, and the frequency of the a allele was 7.14%. While the frequencies of ecNOS4 a/a, ecNOS4 a/b,and ecNOS4 b/b in the EH group were 0.49%, 19.32% and 80.19% respectively. The frequency of the a allele in EH group (n=42, 10.15%) was significantly higher than that in the healthy group (n=33, 7.14%)(P<0.05). The plasma NOx level of the EH group was 70.04±14.68 mol/L, and significantly lower than that 84.09±27.27 mol/L in the healthy group (P<0.05). Similarly, both the plasma TNOS and iNOS activities of the EH group were 35.49±12.8 U/ml and 14.92±7.93 U/ml, and markedly lower than that 41.47±13.2 U/ml and 10.11±6.21U/ml in the healthy group (P<0.05). But the activities of eNOS in the EH group and healthy group were not significantly different (P>0.05).ConclusionThe variations of ecNOS4 gene locus may be responsible for the decrement of plasma NOx, both plasma NOx level and activity of NOS decreases in EH patients, so it may be a genetic susceptibility marker for EH of the Han nationality in China.

Objective:Based on the detection of CD4+IL17+Th17 and CD4+CD25+Foxp3+Treg cells in the peripheral blood of patients with human papilloma virus (HPV), the study analyzes the ratio of Th17 to Treg and compares the different expression of cytokine IL-17, IL-10, TGF-β, and IL-23 in the serum. Methods:From September 2014 to June 2016, 119 cases of untreated patients with cervical HPV in-fection were collected at the First Affiliated Hospital of Xinjiang Medical University, which include 46 cases of cervical cancer (CC), 43 cases with cervical intraepithelial neoplasia (CIN)Ⅱ-Ⅲ, and 30 with chronic cervicitis (CCS). The detection of HPV types classified 80 patients as high-risk and 39 as low-risk. Flow cytometry examined Treg and Th17 cells, and enzyme-linked immune sorbent assay was used to test related cytokines. Results:In the infection of high-risk cervical HPV, the rate of the CC group was 87%(40/46), which was higher than that of the CINⅡ-Ⅲgroup and the CCS group, which were 77%(33/43) and 23%(7/30), respectively. For the expression of Th17 and Treg cells in the peripheral blood and the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum, the levels of CC group were also significantly higher than that of the other two groups, and the ratio of Th17 to Treg increased considerably with the se-verity of cervical lesions. The expression of Th17 and Treg cells in the peripheral blood of patients with high-risk cervical HPV were higher than that of patients with low-risk cervical HPV (P<0.05), which was the same for the expression of the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum. The ratio of the Th17 to Treg of patients with high-risk cervical HPV increased remarkably (P<0.05). Conclusion:The expression of Treg and Th17 cells in high-risk patients exhibits an increasing trend, and the ratio of increased Th17 to Treg may directly participate in the process of HPV infection and immune evasion, which plays an important role in the occurrence and development of cervical cancer.
