BACKGROUND: Transplantation of fragments of ovarian cortex is performed without vascular reanastomosis, therefore, to increase the tolerance of ovarian tissue to the freezing-thawing and ischemic injuries is critical for follicular survival and functional longevity of the graft.OBJECTIVE: To investigate the effect of follicle stimulating hormone (FSH) on the morphological and function of sheep ovary tissue in the process of cryopreservation, so that to provide new freezing method for human ovary tissues. METHODS: Healthy BALB/c strain female nude mice were equally and randomly divided into 3 groups and subjected to heterotopic transplantation of fragments of sheep ovarian cortex. (1) Control group: transplantation following sampling; (2) experimental group: transplantation following freezing-thawing, and the solution was free of FSH; (3) FSH group: the freezing and thawing and culture fluid contained FSH. The estrous cycle recovering rate, estrous cycle recovering time, the number of follicle were observed following transplantation. The histological changes, and the level of E2 in blood serum were observed at 4 weeks after transplantation.RESULTS AND CONCLUSION: There were no significant differences in estrous cycle recovering rate and number of follicle/PHF between FSH and control groups (P> 0.05), but the number of follicle was greater than the experimental group (P< 0.05). Moreover, the time of estrous cycle recovering in FSH group was similar to control group, but shorter than experimental group (P < 0.05). There were more developing follicular in FSH group, but few in experimental group at 4 weeks. No significant difference was detected in E2 level in blood serum between FSH and control group (P > 0.05), but significantly greater than the experimental group (P< 0.05). Results show that FSH addition in vitrification fluid can improve ovarian follicle survival following cryopreserved sheep ovary tissue transplantation.

Objective To explore the correlation between the length of peristaltic break (LPB) and the severity of the symptoms in patients with non-erosive reflux disease (NERD) and negative pH monitoring.Methods A total of 35 patients with NERD and negative pH monitoring were enrolled,and at same time 10 healthy individuals were selected as controls.The LPB of esophageal body of both groups was measured by high resolution manometry (HRM).Meanwhile,the symptom of NERD patients with negative pH monitoring was scored.The LPB of esophageal body between the two groups was compared by t test.The correlation between the LPB and the severity of the symptoms in NERD patients with negative pH monitoring was analyzed by Pearson correlation analysis.Results The average LPB of esophageal body of NERD patients with negative pH monitoring was (3.3±0.9)cm,which was longer than that of healthy controls ((1.2 ± 0.4) cm),and the difference was statistically significant (t=9.17,P＜0.01).The symptom score of NERD patients with negative pH monitoring was 21.6± 7.8.There was a positive correlation between the LPB and NERD symptom score (r=0.894,P＜ 0.01).Conclusion The LPB of esophageal body is a kind of expression of esophageal motility dysfunction,which is correlated with the symptom of NERD.

Objectives To investigate HPV infection and its correlati on with the expression of matrix metalloproteinase-9 (MMP-9) and tissue inhibito r of metalloproteinase-1 (TIMP-1) in vulvar squamous cell carcinoma (VSCC). Meth ods HPV6/11 and 16/18 DNA were detected using in situ hybridization in 26 case s of VSCC, 21 cases of vulvar intraepithelial neoplasia (VIN) and 10 specimens o f normal skin. The expression of MMP-9 and TIMP-1 was measured by immunohistoche mical method in these three groups. Results The infection rates of HPV6/11 and 16/18 in VSCC and VIN were 69.23% (18/26) and 38.46% (10/26), 42.86% (9/21) and 28.57% (6/21) respectively, and no HPV6/11 or 16/18 DNA was discovered in norma l skin epidermis. The expression rates of MMP-9 and TIMP-1 in VSCC, VIN and norm al skin epidermis were 92.31%(24/26) and 76.92% (20/26), 90.45% (19/21) and 80.9 5% (17/21), and 80.00% (8/10) and 50.00% (5/10) respectively. MMP-9 expression in HPV positive lesions was higher than that in HPV negative lesions, but no sig nificant difference of TIMP-1 expression was observed in HPV positive and negati ve lesions. Conclusions HPV infection may play a role in the development of VS CC. The higher expression of MMP-9 comparing with that of TIMP-1 may be an early marker of tumor progression in VSCC, and HPV infection may facilitate the invas ion and metastasis of VSCC.

Objective To study the effects ofShenqi YizhiGranules (SQYZ) on learning and memory and content of Aβ1-42 of cerebral tissue in 5XFAD mice with Alzheimer’s disease; To discuss its mechanism on improving learning and memory ability of 5XFAD mice.Methods Four-month-old C57BL?6 wild type mice were randomly divided into NS control group and SQYZ control group, and the 5XFAD mice were randomly divided into model group, SQYZ group and huperzine-A (HupA) group, 15 mice in each group. Each group were given same volume for gavage for 60 d. After treatment, the learning and memory ability were evaluated by nesting test, passive avoidance and Morris water maze test. The senile plaques and content of Aβ1-42, ionized calcium binding adapter molecule 1 and glial fibrillary acidic protein in cerebral cortex and hippocampus were detected by immunohistochemical staining and immunofluorescence, respectively.Results Compared with NS control group, the score of nesting test in model group significantly decreased; the step-through latency in passive avoidance was shortened and the escape latentcy in Morris water maze test was prolonged; the quantity of senile plaques and content of Aβ1-42 increased in cerebral cortex and hippocampus; the activation of glial cells significantly increased. In the SQYZ group, the above-mentioned indexes reached or approached the level of wild type control mice. The difference between SQYZ group and model group was statistically significant (P<0.05,P<0.01).Conclusion SQYZ improved learning and memory ability in 5XFAD mice, which may be related to reduction of senile plaques, inhibition of over activation in glial cells and reduction of content of Aβ1-42 in cerebral cortex and hippocampus.

Objective:To investigate the value of quantitative CT (QCT) body component parameters before and after transcatheter arterial chemoembolization (TACE) as prognostic indicator for patients with hepatic cell carcinoma (HCC).Methods:Retrospective analysis was performed on 40 patients with advanced HCC who received TACE treatment in Anhui Provincial Hospital Affiliated to Anhui Medical University from November 2013 to May 2017, all of them received QCT scanning before and after treatment. The information were recorded, including gender, age, alpha-fetoprotein (AFP), TNM stage, liver function Child-Pugh grade, portal venous thromboembolism, cirrhosis, maximum tumor diameter, tumor type, and frequency of interventional therapy. QCT parameters were measured before and after treatment, including L1, L2 bone mineral density (BMD), L3-level paravertebral muscle area (MA), subcutaneous fat area (SFA) and visceral fat area (VFA), and the change rate of QCT parameters (ΔBMD, ΔMA, ΔSFA, ΔVFA) before and after TACE were calculated after the QCT scan interval was standardized. The cut-off values of ΔBMD, ΔMA, ΔSFA and ΔVFA to diagnose the prognosis of HCC patients after TACE were obtained by drawing the ROC curves. The Kaplan-Meier method was used to calculate the survival rate, the Log-rank method was used for univariate analysis, and the Cox regression analysis model was used for multivariate analysis to screen out independent factors affecting the prognosis of HCC patients after TACE.Results:ROC curve analysis showed that the cut-off values of ΔBMD, ΔMA, ΔSFA and ΔVFA to diagnose the prognosis of HCC patients after TACE were -8.64%, -6.84%, -9.84% and 5.70%, respectively. Univariate analysis showed that AFP, TNM stage, liver function Child-Pugh grade, portal venous thrombosis, tumor type and ΔMA, ΔSFA, ΔVFA had statistically significant effects on prognosis ( P<0.1). Multivariate analysis showed that ΔMA, ΔVFA and portal venous thromboembolism were independent influencing factors for the prognosis of HCC patients after TACE treatment ( P<0.05). Conclusions:ΔMA, ΔVFA and portal venous thromboembolism have reference value for prognosis assessment of TACE treatment for HCC patients, and QCT body composition analysis is helpful to evaluate the prognosis of HCC patients.
