Objective:To explore the application effect of standardized intraoperative temperature management in patients with laparoscopic partial nephrectomy (LPN) .Methods:Using the convenient sampling method, a total of 100 patients who underwent LPN in Wuxi Second People's Hospital from July 2019 to June 2021 were selected as research objects. They were randomly divided into the control group and the observation group, with 50 cases in each group. The control group was given conventional thermal insulation measures, while the observation group was given standardized intraoperative temperature management on the basis of the control group. The differences in postoperative recovery indexes and body temperature at each time point were compared between the two groups.Results:The recovery time of anesthesia, recovery time of spontaneous respiration and stay time of anesthesia recovery room in the observation group were less than those in the control group, and the differences were statistically significant ( P<0.01). The complication rate of observation group was 2% (1/50), lower than 16% (8/50) of control group, and the difference was statistically significant ( P<0.05). The body temperature of observation group was higher than that of control group at 30 min after operation, 60 min after operation, immediately after operation and at the time of recovery, and the differences were statistically significant ( P<0.01) . Conclusions:The application of standardized body temperature management in LPN surgery can shorten the recovery time of anesthesia and help to maintain the stability of intraoperative temperature.

Objective:To investigate the effect of serine/arginine-rich splicing factor 2 (SRSF2) on ferroptosis and its possible mechanism in glioblastoma cells.Methods:The online database of gene expression profiling interactive analysis 2 (GEPIA 2) and Chinese Glioma Genome Atlas were used to analyze the expression of SRSF2 in glioblastoma tissue and its association with patients prognosis. To validate the findings of the online databases, the pathological sections of glioblastoma and non-tumor brain tissues from Tianjin Medical University General Hospital, Tianjin, China were collected and analyzed by using immunohistochemistry. Silencing SRSF2 gene expression in glioblastoma cells by siRNA was analyzed with Western blot. The proliferation index was detected by using CCK8 assay. The rescued experiment was conducted by using expression plasmid of pcDNA3.1(+)-SRSF2. The activity of ferroptosis was assessed by using the levels of iron ions and malondialdehyde in glioblastoma cells and the changes in the ratio of glutathione to oxidized glutathione. The changes of gene expression and differential pre-mRNA alternative splicing (PMAS) induced by SRSF2 were monitored by using the third-generation sequencing technology analysis, namely Oxford nanopore technologies (ONT) sequencing analysis.Results:SRSF2 expression was higher in glioblastoma tissues than non-tumor brain tissues. Immunohistochemistry also showed a positive rate of 88.48%±4.60% in glioblastoma tissue which was much higher than the 9.97%±4.57% in non-tumor brain tissue. The expression of SRSF2 was inversely correlated with overall and disease-free disease survivals ( P<0.01). The proliferation index of glioblastoma cells was significantly reduced by silencing with SRSF2 siRNA ( P<0.01) and could be reversed with transfection of exogenous SRSF2. The levels of intracellulariron ions and malondialdehyde increased ( P<0.05), but the glutathione/oxidized glutathione ratio and the expression of key proteins in the glutathione pathway remained unchanged ( P>0.05). ONT sequencing results showed that silencing SRSF2 in glioblastoma cells could induce a significant alternative 3' splice site change on ferroptosis suppressor protein 1 (FSP1). Conclusion:SRSF2 inhibits the ferroptosis in glioblastoma cells and promotes their proliferation, which may be achieved by regulating FSP1 PMAS.

Background Occupational stress has been shown to be an important factor affecting the mental health of workers. The role of affective commitment to the organization and overcommitment to work cannot be ignored. However, there is a lack of research on this topic in China. Objective To explore a potential mediating effect of affective commitment on how occupational stress affects the mental health of medical staff and a potential moderating effect of overcommitment on the mediating effect of affective commitment. Methods A total of 1372 health care workers in a tertiary Grade A hospital in Lanzhou City were selected as study subjects for a cross-sectional survey. The occupational stress, emotional commitment, and psychological distress of the subjects were evaluated by the Effort-Reward Imbalance Scale, Affective Commitment Scale, and Kessler 10 Scale. SPSS 26.0 was used for correlation analysis, mediation analysis, and moderated mediation analysis. Common method bias wasevaluated by Harman one-factor test. Results A total of 1372 questionnaires were distributed, of which 1277 valid questionnaires were returned, with a valid recovery rate of 93.08%. The mean occupational stress score was 1.14±0.23, the mean overcommitment score was 20.26±3.21, the mean affective commitment score was 20.25±3.34, and the mean psychological distress score was 26.26±7.90. The Spearman correlation analysis results showed that occupational stress among medical staff was positively correlated with overcommitment and psychological distress (r=0.153, 0.410, P＜0.01) and negatively correlated with affective commitment (r=−0.341, P＜0.01); overcommitment was negatively related to affective commitment and positively related to psychological distress (r=−0.107, 0.312, P＜0.01); affective commitment was negatively related to psychological distress (r=−0.464, P＜0.01). The positive effect of occupational stress on psychological distress of medical staff was significant (b=0.41, t=15.42, P<0.001); affective commitment presented a partial mediating effect on the relationship between occupational stress and psychological distress (effect value=0.13), accounting for 31.71% of the total effect; overcommitment moderated the process of occupational stress-affective commitment-psychological distress (P＜0.01). Conclusion Affective commitment of medical staff has a partial mediating effect on the relationship between occupational stress and psychological distress, and overcommitment plays a significant role in moderating the process of occupational stress-affective commitment-psychological distress.
