ABSTRACT
Objective:To analyze independent influencing factors of surgical textbook outcome (TO) in patients with gallbladder carcinoma, and to establish a nomogram for predicting TO and evaluated the predictive ability.Methods:Patients with gallbladder carcinoma who underwent surgery in Department of Hepatobiliary and Pancreatic Surgery at Dongfang Hospital Affiliated to Shanghai Tongji University and Department of Biliary Tract Surgery Ⅰ, Third Affiliated Hospital of Naval Medical University (Shanghai Eastern Hepatobiliary Surgery Hospital) from January 2013 to December 2018 were included and the clinical features were retrospectively analyzed. A total of 232 patients were included, including 114 males and 118 females, aged (61.0±9.8) years. According to whether TO reached or not, they were divided into TO group ( n=86) and non-TO group ( n=146). Univariate and multivariate logistic regression were used to analyze the independent influencing factors of TO. The predictive nomogram model of TO was constructed. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive ability of the model, and the consistency of the predictive model was evaluated by the consistency curve graph and the Hosmer-Lemeshow test. Results:The 1-year and 3-years cumulative survival rates of patients with gallbladder carcinoma in the TO group (86.0% and 62.8%) were better than those in the non-TO group (46.6% and 27.3%), and the difference was statistically significant (χ 2=60.74, P<0.001). In multivariate analysis, higher T stage ( OR=0.16, 95% CI: 0.03-0.79, P<0.001) and cervical gallbladder cancer ( OR=0.14, 95% CI: 0.02-0.94, P=0.004) had the greatest negative association with a TO, and the higher the degree of tumor differentiation ( OR=7.08, 95% CI: 1.34-37.56, P=0.001), the easier it is to achieve TO. The ROC curve showed that the area under the curve of the predictive model was 0.84 (95% CI: 0.79-0.90), suggesting that the model had good predictive performance. A nomogram to assess the probability of TO was developed and had good accuracy in both the consistency curve and Hosmer-Lemeshow test (χ 2=5.77, P=0.673). Conclusion:Tumor T stage, tumor differentiation degree and tumor location are independent influencing factors for achieving TO in patients with gallbladder carcinoma after surgery. The nomogram model constructed according to the above conclusions could accurately predict the probability of reaching TO.

ABSTRACT
Gallbladder cancer is a high malignancy which is predisposed to invade adjacent organs and have lymph node metastasis. Gallbladder cancer is not sensitive to radiotherapy or chemotherapy with the worst prognosis among biliary tract cancers. At present, radical resection is the only possible method to cure gallbladder cancer. However, there are still many controversies about the surgical strategies, the extent of liver resection and lymph node dissection, and the treatment of incidental gallbladder cancer. In addition, under the background of the great success of immunotherapy and targeted therapy in a variety of solid tumors, it is also a question worthy of further considerations that whether the status of surgery in the treatment of advanced gallbladder cancer will be changed in the near future.
ABSTRACT
Objective:To evaluate the efficacy and safety of clip-with-endoloop method during endoscopic submucosal dissection (ESD) in treatment of early gastric angle cancer and precancerous lesions.Methods:A total of 59 patients with early gastric angle cancer or precancerous lesions underwent ESD from January 2018 to December 2018 were randomly divided into the routine ESD group ( n=28) and the clip-with-endoloop group ( n=31). The frequency of supplementary submucosal injection, ESD procedure time, area of the resected specimen, dissection time, submucosal dissection speed, complete resection rate and complications were compared between the two groups. Results:The frequency of supplementary submucosal injection in the clip-with-endoloop group was less than that in the routine ESD group (2.3±1.1 VS 3.7±1.4, t=4.557, P<0.001). There was no significant difference in the area of the resected specimen between the two groups (12.7±2.6 cm 2 VS 11.7±2.7 cm 2,t=1.485, P=0.143). The ESD procedure time (72.4±24.7 min VS 93.6±28.9 min, t=3.043, P=0.004) and dissection time (67.7±23.3 min VS 88.2±28.3 min, t=3.054, P=0.003) in the clip-with-endoloop group were significantly shorter compared with those in the routine ESD group. The submucosal dissection speed in the clip-with-endoloop group was higher than that in the routine ESD group (20.2±3.2 mm 2/min VS 14.3±3.4 mm 2/min, t=6.879, P<0.001). The complete resection rate was 100.0% in the both groups. No perforation or postoperative bleeding occurred in the two groups. The incidence of intraoperative bleeding in the clip-with-endoloop group was lower than that in the routine ESD group [19.4% (6/31) VS 35.7% (10/28), χ2=1.992, P=0.158]. Conclusion:Clip-with-endoloop method makes ESD procedures easier and faster, with a lower possibility of intraoperative bleeding in treatment of early gastric angle cancer.

ABSTRACT
BACKGROUND:To build up an effective method of isolating and culturing granule cels is a pivotal step to enhance fertilization-embryo transfer rate. Current studies mainly focus on the isolation methods of human ovarian granulosa cels rather than cel counting, purity and subsequent growth. OBJECTIVE: To establish the effective methods of isolating, purifying and culturing human ovarian granulosa cels in vitro. METHODS: Folicular fluid was harvested from women undergoing fertilization-embryo transfer procedures. Human ovarian granulosa cels were obtained from the folicular fluid by lysis treatment, precipitation method or density gradient centrifugation. Granulosa cel mucus masses were digested with type I colagen enzyme or hyaluronidase and then cultured in the culture medium with or without autologous folicular fluid. RESULTS AND CONCLUSION: Lysis treatment yielded the largest amount of granulosa cels compared to the precipitation method and density gradient centrifugation (P > 0.05,P < 0.05, respectively). Cels prepared by the three methods showed the same cel viability. After 24 hours of culture, the precipitation method obtained the largest amount of adherent granulosa cels (P < 0.05); and the density gradient centrifugation obtained the least amount of cels (P < 0.05). Compared with type I colagen enzyme, hyaluronidase took less time to digest the cels thoroughly. Autologous folicular fluid could promote the growth and survival of granulosa cels. These findings indicate that the precipitation method, though time-consuming, can obtain the highest cel viability and harvested the largest amount of granulosa cels after culture; hyaluronidase is more suitable for digesting granulosa cel mucus mass than type I colagen enzyme; autologous folicular fluid added into the culture medium is more conducive to granulosa cel growth.
