Objective To research the effect of postoperative intervention on the quality of life of cervical cancer patients, in order to provide the basis for improve the quality of life of patients after operation. Methods 86 cases of cervical cancer were divided into control group and intervention group by simple random grouping method, each group contained 43 cases. The postoperative interventions were used in the intervention group after 3 months, including psychological assessment, individual education, pelvic floor rehabilitation therapy, open patient service hotline and regular follow-up. Before and after 6 months of surgery, the quality of life of cervical cancer patients were investigated. Results The index score of social relations [(48.84±4.63) scores vs. (40.72±3.74) scores], psychological field [(73.72±2.84) scores vs. (64.07±4.06) scores], environmental field [(64.07±4.08) scores vs. (55.70±4.86) scores], physiological index [(44.77±4.22) scores vs. (36.53±4.29) scores], independence [(64.81 ±5.85) scores vs. (53.95±5.91)], quality of life [(88.30±5.75) scores vs. (76.65±5.21) scores] in cervical cancer patients were lower than those in the control group (all P<0.05). Multiple stepwise regression analysis showed that the understanding degree of cervical cancer, radiotherapy and chemical therapy after surgery, postoperative complications, caregivers care in place and psychological intervention had correlation with the quality of life of patients in intervention group (all P<0.05), while retain ovarian and education degree had no correlation with the quality of life of patients after operation (both P>0.05). Conclusions The quality of life of cervical cancer patients after surgery is poor, and it is affected by many factors. The targeted interventions should be used in clinical works, which can significantly improve the quality of life of patients.

Objective To investigate the methods and techniques of simplified binding pancreaticojejunostomy for patients with periampullary malignant tumor after radical pancreatoduodenectomy (RPD). Methods From March 2005 to May 2010, 323 patients with periampullary malignant tumor received RPD at the Tongji Hospital of Huazhong University of Science and Technology, and their clinical data were retrospectively analyzed.Simplified binding pancreaticojejunostomy was applied after RPD: the distal end of pancreas was freed for 3-4 cm;a No. 6 or No. 8 silicone urinary catheter was inserted into the pancreatic duct for 4-5 cm, and the remaining urinary catheter (6-8 cm) out of the pancreatic duct was sutured to the pancreatic stump with absorbable sutures.The cutting end of the jejunum (2-3 cm) was everted, and the everted mucosa of the jejunum ( 1 cm) was injured by electrocautery, then the everted jejunum was reverted to its normal position. The cutting end of the mesentery of jejunum and its opposite side, as well as the mid-point of these two parts were sutured symmetrically with the lower and upper edges of the pancreas, and with the capsule of pancreas between them. The everted jejunum was wrapped over the pancreatic stump and sutured it to the pancreas for fixation. The cutting end of the jejunum was bound to the pancreatic stump with 1-0 absorbable suture after confirming the jejunum was completely invaginated into the pancreas. The alimentary tract was reconstructed by using Child's method. Results Simplified binding pancreaticojejunostomy was successfully completed in all patients, Pancreatic fistula was detected in one patient who was complicated with anastomotic bleeding on the third day after secondary laparotomy. The patient was discharged with catheter and spontaneously recovered one month later. Pancreatic fistula was also detected in two patients with distal bile duct carcinoma and two patients with carcinoma in the uncinate process of pancreas at postoperative day 3, 6, 8 and 11, and they were cured by expectant treatment. The incidence of pancreatic fistula was 1.5% (5/323). Conclusion Simplified binding pancreaticojejunostomy is simple, safe and feasible, and it can significantly reduce the incidence of pancreatic fistula.

Objective:To observe the effect of non-vitrectomy in the treatment of idiopathic macular epiretinal membranes (IMEM).Methods:This study is a randomized controlled trial. From December 2017 to December 2018, 60 IMEM patients (60 eyes) diagnosed in Weifang Eye Hospital were included in the study. BCVA, intraocular pressure (IOP) and OCT were performed in all patients. The BCVA examination was performed using the international standard visual acuity chart, which was converted to logMAR. The CMT was measured by OCT. According to the surgical methods, the patients were divided into non-vitrectomy group and control group, 30 patients (30 eyes) in each group. The age ( t=1.723), logMAR BCVA ( t=1.703), CMT ( t=-0.956), IOP ( t=-1.434) were not significantly different between the two groups ( P=0.090, 0.094, 0.343, 0.157). 23G vitreous cutting system was used in all eyes. The macular epiretinal membranes was removed by non-vitrectomy in the non-vitrectomy group and by vitrectomy in the control group. The relevant examination with the same equipment and methods before the operation at 1 week and 1, 3, 6 months after operation. The time of surgery, the changes of BCVA, CMT and postoperative complications in the two groups were observed comparatively. Variance analysis of repeated measurements was performed for the comparison of BCVA, CMT and IOP after surgery in the two groups. Wilcoxon rank sum test of two independent samples was performed for the degree of vision improvement. The incidence of postoperative complications was compared by χ2 test. Results:At 6 months after operation, BCVA increased in 24 eyes (80%) and unchanged in 6 eyes (20%) in the non-vitrectomy group. Compared with preoperative BCVA, the difference was statistically significant ( P<0.05). BCVA increased in 25 eyes (83.4%), unchanged in 4 eyes (13.3%) and decreased in 1 eye (3.3%) in the control group. Compared with preoperative BCVA, the difference was statistically significant ( P<0.05). There was no significant difference between the two groups in BCVA improvement degree after operation ( Z=-0.26, P>0.05). At 6 months after operation, the average logMAR BCVA was statistically significant compared with the preoperative in the non-vitrectomy group ( P=0.002, 0.005) and control group ( P=0.004, <0.001). Visual stability occurred 1 month after operation in the non-vitrectomy group and 3 months after operation in the control group. The effective operative time of the non-vitrectomy group and control group was 4.50±1.41 and 15.50±2.33 min, respectively. The difference of effective operation time between the two groups was statistically significant ( t=-22.12, P <0.05). After surgery, no significant complications were found in the non-vitrectomy group. In the control group, there were 3 eyes with low IOP and 1 eye with macular hole during operation. Conclusions:Non-vitrectomy and vitrectomy have similar effects on IMEM. Non-vitrectomy has short effective operation time, faster recovery after surgery and no obvious complications.
