Objective:To explore the effect and mechanism of different processing motivation on college students' intergroup interaction willingness by technology of eye movement.Methods:Sixty college students conforming to the study conditions were selected from Northwest Normal University and randomly divided into ingroup motivation group ( n=30) and outgroup motivation group ( n=30) according to the random number table method. Subjects of the two groups first participated in the eye movement task, and then participated in the partner selection task.In the eye movement task, the percentage of time that subjects looked at faces of different groups was recorded.And in the partner selection task, the number of selections that subjects selected faces from different groups was recorded.SPSS 20.0 software was used for repeated measurement analysis of variance. Results:(1) In the eye movement task, there was a significant interaction of group and face group type ( F=13.37, P<0.001), but the main effects of group( F=3.23, P=0.077), and face group type ( F=0.09, P>0.05) were not significant. Further simple effect analysis showed that the percentage of time that the ingroup motors looked at the yellow race((16.00±0.06)%) was significantly higher than that of the outgroup motors ((12.00±0.04)%), and the percentage of time that the outgroup motors looked at the white race((17.00±0.06)%) was significantly higher than that of the ingroup motors ((9.00±0.04)%). (2) In the task of partner selection, there was a significant interaction among group, face group type and face old and new types( F=4.38, P=0.041), and the main effect of face group type was significant( F=14.87, P<0.001). The main effect of old and new types of face was significant( F=8.88, P=0.004), but the main effect of group was not significant ( P>0.05). Further simple effect analysis showed that the two groups of college students had statistically significant differences in the selection times of familiar faces from different groups( F=11.51, P=0.001). The number of times that the ingroup generator (5.51±1.14) selected the familiar yellow race as its partner was significantly greater than that of the outgroup generator (2.30±0.65). The number of times that the outgroup generator (5.40±1.00) selected the familiar white race as its partner was significantly greater than that of the ingroup generator (3.47±0.94). (3)Preferential attention to the ingroup members was a mediator between processing motivation and intergroup interaction willingness (mediating effect=0.20, 95% CI=0.02-0.31). Conclusion:Ingroup processing motivation has a threatening effect on college students' intergroup interaction willingness, outgroup processing motivation has a promoting effect on college students' intergroup interaction willingness, and processing motivation affects intergroup interaction willingness through ingroup bias.

Objective:To Investigate the postoperative sexual function outcomes in patients with bladder cancer who underwent robot-assisted radical cystectomy (RARC)or laparoscopic radical cystectomy(LRC)followed by orthotopic neobladder reconstruction.Methods:We performed a retrospective review of 84 bladder cancer patients having undergone laparoscopic radical cystectomy(LRC)and robotic-assisted radical cystectomy(RARC)with≥21 IIEF-5 in our institution from Jan 2014 to Jan 2019. All of them were diagnosed as high grade urothelial carcinoma by biopsy or TURBT. Biopsy of the posterior urethra and bladder neck reveal negative result of tumor invasion. Their PSA level was less than 4.0 ng/ml with negative result of DRE. All patients undergone laparoscopic radical cystectomy and orthotopic neobladder reconstruction by one medical team. 45 patients underwent robotic assistant radical cystectomy(RARC group), and the rest of patients 39 were treated with laparoscopic radical cystectomy(LRC group). In RARC group, the mean age were 53 years old(ranging 50-67 years old)and clinical stage of the tumor was cT 1 in 10 patients, cT 2 in 21 patients and cT 3 in 14 patients. In the LRC group, the mean age were 56 years old(ranging52-65 years old) and the clinical staging of the tumors was 6 patients in cT 1, 23 patients in the cT 2 and 12 patients in the cT 3. The RARC group paid special attention to the protective function of the following surgical details: ①To detect the abdominal organs, reveal the pelvic cavity, observe the blood vessels and ureter, open the perinatal membrane next to the cross of the ureter, along the outer venous veins and closed-hole nerves around the standard or expand the pelvic lymph node cleaning. In this study, the patients who did not have obvious suspected lymph node metastasis were removed within the standard range of the pelvic lymph nodes on both sidesin order to protect the nerves at the pelvic floor as much as possible. ② With the robot 3rd arm lifting the bladder, the peritoneum was opened at the site of seminal vesicle and ampulla of vas deferent duct, which connected to the two sides with the open peritoneum. Along the vasectomy and the sac free, the denonvillier fasica was opened and exposing the back of the prostate. With the third arm pulling down, the umbilical ligament was observe. The peritoneal was opened to the retropubic space so that the prostate region was revealed. Continue to dissect the bladder front space until the pelvic fascia and the osteopathic prostate ligament are exposed. The Hem-o-1oks were used to ligate the bilateral bladder lateral ligaments. The bladder and prostate were removed in the fascia level. The NVB bundle on both sides was kept to the apex of prostate. The urethra was exposed and remove the catheter.With Hem-o-lok clamping, the urethra was dissected in the level of prostatic apex. The distal end of urethral tissue was sent to the rapid freeze pathology examination. In the procedure of prostate removing, parallel prostate fascia excision was considered and pubo-prostatic ligament could be preserved.③ Preserving the bilateral neurovascular bundle (NVB) and try to avoid the damage of NVB. Retaining the bladder lateral ligament neurovascular bundle. Retaining the1.2-1.5 cm urethra and surrounding continent control structure. The cold knife is advocated. Blood vessel clamp can be used to stop bleeding. We compared with operative time, bleeding amount, postoperative hospitalization, IIEF-5 scores and satisfaction of sexual between those groups. Results:All operations were successfully performed without conversion and serious surgical complications. The operative time in the RARC group and LRC group were [(313.5±31.9)min and (276.5±32.3)min, P>0.05] .The intraoperative amount of blood loss and postoperative hospitalization were [(190.1±44.1) ml and (212.3±39.2) ml, P>0.05], [(14.3±2.1) d and (15.2±3.0) d, P>0.05]. There was no significantly difference between the two groups. The median follow-up period of 84 patients was 18 months. The IIEF-5 score of the RARC group was higher than LRC group at 6 months(18.5±1.6 vs.10.6±1.3)and 12 months (18.6±2.4 vs.11.2±1.4) ( P<0.05). In addition, the satisfaction of sexual in the RARC group was relative better than LRC group (both P<0.05) at 6 months[44.4%(20/45)vs.25.6%(10/39)], and 12 months[51.1%(23/45) vs.28.2%(11/39)] post-operation. Conclusion:Robot-assisted radical cystectomy(RARC) and orthotopic neobladder reconstruction revealed relative better recovering in post-operative sexual function and improvements in patient quality of life.

Objective:To analyze the survival time, prognostic factors and the value of postoperative thoracic radiotherapy in resected small cell lung cancer (SCLC) patients.Methods:Clinic opathological data of SCLC patients who received surgical treatment in Cancer Hospital & General Hospital of Ningxia Medical University from April 2014 to September 2021 were enrolled in this retrospective study. All patients were subject to follow-up. The survival time of SCLC patients was evaluated by Kaplan-Meier method. Univariate and multivariate analyses of prognostic factors were performed by Cox proportional hazard model.Results:A total of 64 patients with SCLC were enrolled in the study. The 5-year overall survival (OS) rate was 43.5%. Univariate analysis showed that TNM staging ( P=0.027), postoperative neutrophil-lymphocyte ratio (NLR) ( P=0.039) and adjuvant thoracic radiotherapy ( P=0.041) were the prognostic factors. Multivariate analysis showed that TNM staging ( P=0.038) and adjuvant thoracic radiotherapy ( P=0.022) were the prognostic factors in patients with SCLC. The 5-year OS rates of patients with and without adjuvant thoracic radiotherapy were 71.6% and 35.4% ( P=0.028), respectively. There was a statistically significant difference in the 5-year OS rates between pathological stage N 2 SCLC patients with or without adjuvant thoracic radiotherapy (75.0% vs. 0%, P=0.030). Conclusions:TNM staging and postoperative adjuvant thoracic radiotherapy are prognostic factors in patients with SCLC undergoing surgical treatment. Pathological stage N 2 SCLC patients can benefit from adjuvant thoracic radiotherapy.
