Objective:To retrospectively analyze the clinical effects and complications of alcohol inactivation, irradiation inactivation, and liquid nitrogen inactivation in the treatment of femur osteosarcoma in children, in an attempt to provide a theoretical basis for clinical selection of in vitro inactivation methods of tumor bone segment. Methods:The clinical data of 93 children with femur osteosarcoma admitted to the Department of Bone and Soft Tissue, the Affi-liate Cancer Hospital of Zhengzhou University from January 2008 to December 2017 were retrospectively analyzed, and 40 children, including 21 males and 19 females, aged 8-18 (13.65±2.87) years, who were treated with in vitro inactivation and replantation of autogenous tumor bone segment, were screened.Among these children, there was alcohol inactivation in 15 cases, irradiation inactivation in 12 cases, and liquid nitrogen inactivation in 13 cases.A comparison was drawn on these 3 inactivation methods with respect to bone healing time, bone healing rate, tumor recurrence rate, infection rate, fracture or fixation failure rate, and revision rate. Results:All those 40 children were subject to valid medical followed-up, with the alcohol inactivation group for (102.60±16.55) months, the irradiation inactivation group for (59.33±6.39) months, and the liquid nitrogen inactivation for (36.85±6.49) months.The difference in follow-up time of 3 groups was statistically significant ( P<0.05). Compared with other 2 groups, the index of bone healing time, bone healing rate, infection rate and revision rate in the alcohol inactivation group were unfavorable, which showed a significant difference (all P<0.05); However, there was no significant difference in the recurrence rate, fracture rate or fixation failure rate compared with other 2 groups (all P>0.05); There was no significant difference in all above indexes between the irradiation group and the liquid nitrogen group (all P>0.05). Conclusions:Three in vitro inactivation methods for the treatment of tumor bone segment are safe and reliable.The alcohol inactivated bone has a long healing time and more complications.Both irradiation inactivation and liquid nitrogen inactivation are clinical options, but irradiation inactivation requires professional equipment, which may limit the clinical application.

Objective:
To analyze the feasibility and safety of enhanced recovery after surgery (ERAS) in colorectal surgery in municipal hospitals.
Methods:
The clinical data of patients with colorectal cancer in Zhangzhou Affiliated Hospital of Fujian Medical University from June 2016 to December 2018 were retrospectively analyzed. A total of 50 patients who underwent laparoscopic surgery combined with ERAS in the perioperative period were selected as the ERAS group, and 50 patients who underwent laparoscopic surgery combined with conventional methods in the perioperative period were treated as the control group. The general data were compared in the two groups, including age, gender, body mass index and the tumor site. The postoperative recovery was compared including fart time, defecation time, total fluid food intake time, nutritional indexes, postoperative leaving hospital time. And the postoperative complications were also compared, including wound infection, lung infection, anastomotic fistula, abdominal infection as well as the urinary infection.
Results:
The first fart time and total fluid food intake time in the ERAS group were earlier than those in the control group [(1.5±0.5) d vs. (2.1±0.8) d, (2.2± 0.8) d vs. (3.4±1.6) d], and the differences were statistically significant (
