Abstract
Objective: To discuss the prediction of round window(RW) visibility in cochlear implantation(CI) with temporal bone high resolution computed tomography(HRCT). Methods: From January 2013 to January 2017, 130 cases underwent both HRCT and CI in our hospital were analyzed. The distance from facial nerve to posterior canal wall(FWD), the angle between facial nerve and inner margin of round window(FRA), and the angle between facial nerve and tympanic anulus to inner margin of round window(FRAA) were detected at the level of round window on axial temporal bone HRCT. A line parallel to the posterior wall of ear canal was drawn from the anterior wall of facial nerve at the level of round window on axial temporal bone HRCT and its relationship with round window was detected (facial-round window line, FRL): type0-posterior to the round window, type1-between the round window, type2-anterior to the round window. Their(FWD, FRA, FRAA, FRL) relationships with intra-operative round window visibility were analyzed by SPSS 17.0 software. Results: FWD(F=18.76, P=0.00), FRA(F=34.57, P=0.00), FRAA (F=14.24, P=0.00) could affect the intra-operative RW visibility significantly. RW could be exposed completely during CI when preoperative HRCT showing type0 FRL. RW might be partly exposed and not exposed when preoperative HRCT showing type1 and type2 FRL respectively. Conclusion: FWD, FRA, FRAA and FRL of temporal bone HRCT can predict intra-operative round window visibility effectively in CI surgery.

Abstract
OBJECTIVE To investigate the effects of the leflunomide (LEF) on the size of the transplanted endometriosis (EMS) lesions and trans- forming growth factor (TGF) -β1gray level in SD rats. MATERIALS AND METHODS EMS was surgically induced in rats by autologous trans- plantation and the focal volume was also measured. The rats were divided into three groups: group A: normal SD rats, group B: rats irrigated by one ml-kg⁻¹d⁻¹ saline for three weeks, and group C: rats irrigated by 35 mg-kg⁻¹d⁻¹ LEF for three weeks. The rats were then sacrificed and measured their focal volume and TGF-β1 gray value with immunohistochemical method. RESULTS The sizes of the focal volume in group C were significantly reduced compared to the rats before feeding, and the volume in group C was smaller than group B after feeding and so was the TGF-β1. CONCLUSION LEF could be a new therapeutic drug for EMS.

Abstract
OBJECTIVE To establish a Mongolian gerbils model by long-term infection of Helicobacter pylori (Hp) with highly-expressed thioredoxin-1 (Trx1) gene and to investigate the histopathological findings of gastric mucosa in Mongolian gerbils. METHODS In this study, 75 healthy male Mongolian gerbils were randomly divided into 3 groups: Hp with highly-expressed Trx1 gene group (n=30), Hp with lowly-expressed Trx1 gene group (n=30), and control group (n=15). The animals underwent gastric perfusion of Hp suspension once a week for 5 weeks. The animals were sacrificed at the end of 4, 20, 34, 48, 70, and 90 weeks after inoculation for detecting Hp colonization by rapid urease test and Warthin-Starry silver staining and histological examination, respectively. RESULTS (1) The Mongolian gerbil model of long-term infection of Hp with highly-expressed Trx1 gene and lowly-expressed Trx1 gene were successfully established. (2) The macroscopic mucosal lesions, including erythema, uneven, erosion, nodules, etc. could be observed in experimental groups. The severity of lesions and the time when lesions occurred in Hp with highly-expressed Trx1 gene group were heavier/earlier than that in Hp with lowly-expressed Trx1 gene group. (3) Histopathologically, the gastric mucosa of Hp with highly-expressed Trx1 gene group showed the mild dysplastic hyperplasia of epithelial cells 34 weeks after the Hp inoculation, and the time was in the 48th week in Hp with lowly-expressed Trx1 gene group. At the end of the 90th week after Hp inoculation, the gastric adenocarcinoma could be detected in the two experimental groups (71.4% vs. 42.8%). The difference between the two experimental groups did not reach statistical significance (P=0.592), which might be due to the small sample capacity and/or short observation time. In addition, there were 2 cases with severe epithelial dysplastic hyperplasia in Hp with highly-expressed Trx1 gene group, and only 3 cases with moderate epithelial dysplastic hyperplasia in Hp with lowly-expressed Trx1 gene group. The uninfected control animals showed no abnormal findings throughout the entire observation period. CONCLUSION Hp with highly-expressed/lowly-expressed Trx1 gene colonizes stably in the glandular gastric mucosa of Mongolian gerbils. The histological changes after infection are similar to those of the Hp infected human being, and Hp with highly-expressed Trx1 gene cause the injury of gastric mucosa and the occurrence of gastric adenocarcinoma. Trx1 maybe the virulence factor that participates in the pathogenesis of gastric cancer and Hp expressing high levels of Trx1 should be highly toxic for gastric diseases in China.

Abstract
INTRODUCTION Angiogenesis plays an important role in the biology of ovarian cancer. The clinical efficacy and side effects of bevacizumab, the vascular endothelial growth factor inhibitor, on survival and toxicity in women with this ovarian cancer, was not conclusive. We performed this systematic review and meta-analysis in order to clarify the efficacy of bevacizumab combined with chemotherapy in the treatment of ovarian cancer. MATERIALS AND METHODS We searched the electronic database of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and CNKI for clinical controlled trials of comparing bevacizumab combined with chemotherapy and chemotherapy alone in the treatment of ovarian cancer. The primary outcomes of eligible studies included median progression-free survival (PFS), overall survival (OS), and toxicities such as enterobrosis, hypertension, albuminuria, congestive heart failure (CHF), neutrophils, thrombosis, and bleeding. The Hazard ratio (HR) and relative risk were used for the meta-analysis and were expressed with 95% confidence intervals (CIs). All the statistical analyses were carried out by Stata 11.0 software (http://www.stata.com; Stata Corporation, College Station, TX, USA). RESULTS We included 5 studies with 1798 cases in the bevacizumab combined with the chemotherapy group and 1810 subjects in the chemotherapy alone group. The pooled results showed that bevacizumab + chemotherapy compared with chemotherapy alone can significant prolong the median PFS (HR, 0.64; 95% CI, 0.46-0.82; P < 0.05) but not the OS (HR, 0.84; 95% CI, 0.59-10.9; P > 0.05); the toxicity analysis showed that the enterobrosis, hypertension, albuminuria, neutrophils, thrombosis, and bleeding were significantly increased in the bevacizumab + chemotherapy group compared with chemotherapy alone (Pall < 0.05). But the CHF risk between the two groups was not statistical different (P > 0.05). CONCLUSION Bevacizumab combined with chemotherapy prolonged the median PFS in patients with ovarian cancer but also increase the risk of developing enterobrosis, hypertension, albuminuria, neutrophils, thrombosis, and bleeding.
