The aim of the present study was to examine the effects of suppression of EphB4 and/or mTOR on the biological behaviors of ovarian cancer cells, and the potential regulatory pathways. Antisense EphB4 vectors and shRNA vectors targeting mammalian target of rapamycin (mTOR) were constructed and transfected into A2780 and SKOV3 cells (two ovarian cancer cell lines). The effects of the antisense EphB4 vectors and the shRNA vectors on the proliferation, apoptosis and invasion of ovarian cancer cells were measured, and the expression of EphB4, mTOR and Akt detected. The results showed that transfection with mTOR shRNA could inhibit growth, induce apoptosis, and reduce invasive ability of ovarian cancer cells, which was accompanied by downregulation of EphB4, mTOR and Akt. The inhibitory effects on cell growth caused by mTOR shRNA alone were weaker than those by antisense pEGFP-C1-EphB4. In the antisense pEGFP-C1-EphB4-transfected cells, it was found that EphB4 knockdown could decrease the mTOR expression and slightly reduce the Akt phosphorylation. Significant suppressive effects on cell growth were observed in cells co-transfected with antisense pEGFP-C1-EphB4 and mTOR shRNA. In co-transfection group, the expression levels of EphB4, mTOR and Akt were distinctly lower than those in other groups. It was concluded that suppression of EphB4 may inhibit the growth of ovarian cancer cells by downregulation of the PI3K/Akt/mTOR pathway, and reverse Akt phosphorylation induced by mTOR shRNA. Inhibition of EphB4 and mTOR combined may cooperatively suppress the biological behaviors of ovarian cancer cells.

Objective:To elucidate the factors influencing the differences in the survival rates of esophageal squamous cell carcinoma (ESCC) patients between the rural and urban regions in China. Methods:A total of 36,723 ESCC patients derived from the clinical data-bases containing 500,000 esophageal and gastric cardia carcinoma cases (1973-2015) of the Henan Key Laboratory for Esophageal Can-cer Research of the First Affiliated Hospital, Zhengzhou University, were analyzed. Of these patients, 33,625 were from the rural re-gions (91.6%), comprising 20,906 male patients with an average age of 58.98 ± 8.71 years and 12,719 females with an average age of 59.59 ± 8.53 years. The remaining 3,098 were from the urban regions and composed of 2,089 male patients with an average age of 60.84±9.10 years and 1,009 females with an average age of 62.46 ± 9.14 years. All the patients underwent radical esophagectomy, de-tailed histopathological diagnosis, and TNM staging. Chi square test, Kaplan-Meier, Log-rank, and Cox proportional hazards regression model were used to analyze the differences between ESCC patients from rural regions and those from urban regions and among the risk factors in prognosis. Results:Kaplan-Meier and Log-rank analysis results showed that the ESCC patients from the rural regions had significantly higher overall survival than the urban patients (χ2=12.971, P=0.000). Further analysis showed that rural patients≥50 years old and diagnosed with stage IIa and IIb (middle stage) ESCC had higher survival rates than urban patients in males and females (male:χ2=16.188, P<0.001;female:χ2=5.019, P=0.025). However, the survival rates of rural and urban patients with stage 0,Ⅰa,Ⅰb (early stage) and Ⅲa, Ⅲc, and Ⅳ (late stage) were similar (P>0.05). The results of Cox proportional hazards regression model analysis showed that age, gender, and TNM stages were independent risk factors for rural and urban ESCC patients. When the rural and urban ESCC patients were both considered, the Cox proportional hazards regression model analysis results showed that male ESCC patients≥50 years old, urban residence, and TNM stages were independent risk factors. Conclusion:Rural ESCC patients have significantly high-er overall survival than urban patients. Male, age of≥50 years old, urban residence, and TNM stages were independent risk factors for ESCC patient survival.

OBJECTIVETo evaluate the safety and efficacy of submucosal tunneling endoscopic septum division (STESD) for escophageal diverticulum.
METHODSClinical data of six consecutive patients with symptomatic esophageal diverticula who received STESD in Endoscopy Center of Zhongshan Hospital, Fudan University from April 2016 to November 2016 were analyzed retrospectively. STESD was performed as following: mucosal entry was made 3 cm from the septum of esophageal diverticulum; submucosal tunnel was created towards the septum; after the satisfactory exposure of the septum, endoscopic division was made down to the bottom of the diverticulum; mucosal closure of the tunnel entry was made. The symptoms were scored using a system modified according to Eckardt score, namely dysphagia, heartburn, regurgitation, weight loss and retrosternal pain with each ranging from 0 to 3 (maximum score 15, minimum score 0, the higher the score, the more severe the symptoms).
RESULTSThere were four males and two females with median age of 56.5 (range 50-67) years. Four patients were epiphrenic diverticula, and the other two were Zenker's diverticula. Median duration of disease was 2.5 years (range 5 months-29 years). No previous treatment was attempted. All the patients completed STESD successfully. The median septum division length was 2.5(1-4) cm. The median number of metallic clips for mucosal closure was 5(2-6). The median operation time was 51.5 (33-135) min. No major adverse events, such as perforation or bleeding were found in perioperative period. The median time of hospital stay was 5(3-9) days. All the patients had symptom relief after operation. One patient with Zenker's diverticulum reported foreign body sensation after operation and experienced relief two weeks afterwards. During a median follow-up time of 5(4-10) months, the median symptom score of 6 cases was 4.5 (1-13) before and 0.5 (0-4) after operation. The symptom scores went down to zero in 3 patients (preoperative scores 13, 1, 1, respectively), and down to 1 in 2 patients with main symptom of backflow (preoperative scores 5, 4, respectively). One patient with 29 years history of disease did not report obvious improvement in symptoms (preoperative and postoperative scores 5, 4, respectively).
CONCLUSIONSubmucosal tunneling endoscopic septum division is efficient and safe to relieve symptomatic esophageal diverticulum in short term.

Objective:To explore the impact of supportive-expressive group therapy on the fear of disease progression and self-perceived burden of patients with early chronic kidney disease (CKD).Methods:A total of 150 early CKD patients in the Nephrology Department of Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine from May 2018 to July 2020 were selected and divided into research group with 88 cases and control group with 88 cases by random number table method. There were 12 cases were lost in the research group, 14 cases were lost in the control group. 76 cases in the research group and 74 cases in the control group were involved in the statistical analysis. The control group was treated with routine nursing while the research group was treated with nursing measures based on supportive-expressive group therapy as well as routine nursing. The effect of intervention was assessed by Fear of disease Progression (FoP) Questionnaire and Self-Perceived Burden Scale (SPBS) before and 12 weeks after the intervention.Results:There was no significant difference in the scores of FoP and Self Perceived Burden Scale (SPBS) between the two groups before the intervention ( P>0.05). After intervention, the scores of emotional reactions, loss of autonomy, partnership/family, anxiety response and the total score of FoP in the research group were (35.79 ± 5.82), (18.52 ± 3.16), (16.23 ± 2.27), (21.57 ± 2.92), (110.81 ± 17.12) respectively, which were lower than those in the control group (47.61 ± 7.13), (24.61 ± 3.97), (24.52 ± 3.71), (31.67 ± 3.87), (147.32 ± 21.72), and the differences were statistically significant ( t values were -18.07 - -10.41, all P<0.05). After intervention, the scores of physical factors, emotional factors and the total score of SPBS in the research group were (10.15 ± 1.82), (10.17 ± 1.86), (24.01 ± 4.25), which were lower than those in the control group (15.87 ± 2.57), (16.81 ± 3.14), (36.39 ± 6.32), and the differences were statistically significant ( t values were -15.76, -15.92, -14.11, all P<0.05). Conclusions:Supportive-expressive group therapy can effectively reduce the early CKD patients′ fear of disease progression and relieve their self-perceived burden.
