ABSTRACT
BACKGROUND@#Findings on the association of genetic factors and colorectal cancer (CRC) survival are limited and inconsistent, and revealing the mechanism underlying their prognostic roles is of great importance. This study aimed to explore the relationship between functional genetic variations and the prognosis of CRC and further reveal the possible mechanism.@*METHODS@#We first systematically performed expression quantitative trait locus (eQTL) analysis using The Cancer Genome Atlas (TCGA) dataset. Then, the Kaplan-Meier analysis was used to filter out the survival-related eQTL target genes of CRC patients in two public datasets (TCGA and GSE39582 dataset from the Gene Expression Omnibus database). The seven most potentially functional eQTL single nucleotide polymorphisms (SNPs) associated with six survival-related eQTL target genes were genotyped in 907 Chinese CRC patients with clinical prognosis data. The regulatory mechanism of the survival-related SNP was further confirmed by functional experiments.@*RESULTS@#The rs71630754 regulating the expression of endoplasmic reticulum aminopeptidase 1 ( ERAP1 ) was significantly associated with the prognosis of CRC (additive model, hazard ratio [HR]: 1.43, 95% confidence interval [CI]: 1.08-1.88, P = 0.012). The results of dual-luciferase reporter assay and electrophoretic mobility shift assay showed that the A allele of the rs71630754 could increase the binding of transcription factor 3 (TCF3) and subsequently reduce the expression of ERAP1 . The results of bioinformatic analysis showed that lower expression of ERAP1 could affect the tumor immune microenvironment and was significantly associated with severe survival outcomes.@*CONCLUSION@#The rs71630754 could influence the prognosis of CRC patients by regulating the expression of the immune-related gene ERAP1 .@*TRIAL REGISTRATION@#No. NCT00454519 ( https://clinicaltrials.gov/ ).

AIM: To observe the effects of single-dose of fentanyl on sedation and agitation during recovery after pediatric adenotonsillectomy day surgery during anesthesia induction. METHODS: A total of 157 children undergoing elective adenotonsillectomy, with ASA physical status I or II, aged 3-10 years were selected during January and March in 2022 in the Second Affiliated Hospital of Wenzhou Medical University. The children were divided into two groups according to random number table method: remifentanil combined with fentanyl group (group RF, n = 78) and remifentanil group (group R, n = 79). Children in group RF received a single-dose injection of 1 μg/kg of fentanyl and 2.5 μg/kg of remifentanil during induction, children in group R received an equal volume of normal saline and 2.5 μg/kg of remifentanil injection. Children in both groups were intubated after propofol induction and anesthetized with combination of sevoflurane-remifentanil. The incidence and severity of emergence agitation (EA), Ramsay sedation score and FLACC pain score in post-anesthesia care unit (PACU), extubation time, recovery time, PACU stay time, discharge time were recorded. RESULTS: Compared with group R, the incidence of EA was significantly lower (38.0% vs. 18.0%, P = 0.005), the maximum PAED score during recovery was significantly lower (7.7 ±3.3 vs. 8.9 ± 3.4, P = 0.027), and the Ramsay sedation score was significantly higher at 15 min after admission of PACU (4.4 ± 1.1 vs. 3.8 ± 1.4, P = 0.01), as well as discharge of PACU (2.0 ± 0.3 vs. 1.8 ±0.4, P = 0.03) in RF group . There was no significant difference in extubation time, recovery time, PACU stay time, discharge time, pain score (discharge of PACU and 2 h after operation) between two groups (P > 0.05). CONCLUSION: A single-dose injection of fentanyl (1 μg/kg) during anesthesia induction can increase the degree of sedation and reduce the incidence of EA in PACU after pediatric daytime adenotonsillectomy.
ABSTRACT
Radiotherapy uses high-energy X-rays or other particles to destroy cancer cells and medical practitioners have used this approach extensively for cancer treatment (Hachadorian et al., 2020). However, it is accompanied by risks because it seriously harms normal cells while killing cancer cells. The side effects can lower cancer patients' quality of life and are very unpredictable due to individual differences (Bentzen, 2006). Therefore, it is essential to assess a patient's body damage after radiotherapy to formulate an individualized recovery treatment plan. Exhaled volatile organic compounds (VOCs) can be changed by radiotherapy and thus used for medical diagnosis (Vaks et al., 2012). During treatment, high-energy X-rays can induce apoptosis; meanwhile, cell membranes are damaged due to lipid peroxidation, converting unsaturated fatty acids into volatile metabolites (Losada-Barreiro and Bravo-Díaz, 2017). At the same time, radiotherapy oxidizes water, resulting in reactive oxygen species (ROS) that can increase the epithelial permeability of pulmonary alveoli, enabling the respiratory system to exhale volatile metabolites (Davidovich et al., 2013; Popa et al., 2020). These exhaled VOCs can be used to monitor body damage caused by radiotherapy.

Objective To explore the related risk factors of aortic esophageal fistula (AEF) after esophageal carcinoma operation.Methods According to the design of case-control study and matching proportion of 1:3,18 cases of AEF after esophageal carcinoma operation treated in the thoracic surgery department of Daping Hospital of Third Military Medical University from 2000 to 2015 served as the observation group,and contemporaneous 54 cases of esophageal carcinoma operation,who had approximate basic diseases or risk factors,were selected as the control group,18 pairs were formed.The risk factors possessed by the observation group before disease onset such as age,sex,tumor TNM stage and tumor location served as the matching variables.The non-matching variables including operation time,preoperative body mass index (BMI),amount of intraoperative hemorrhage,preoperative LDL level,anastomosis mode,postoperative pulmonary complications,postoperative arrhythmia,preoperative hypertension,preoperative diabetes and number of removed lymph nodes were performed the case-control study.Results The univariate Logistic analysis preliminarily screened out 5 risk factors,including preoperative obesity,preoperative LDL level,postoperative pulmonary complications,anstomosis mode and number of removed lymph nodes,the difference in other factors was not statistically significant (P＞ 0.05).The multivariate non-conditional Logistic stepwise regression analysis revealed that preoperative obesity (OR =8.63,95 ％ CI=1.35-17.60),preoperative LDL level (OR =0.81,95 ％ CI =0.23-0.98) and the number of intraoperatively removed lymph nodes (OR =0.32,95 ％ CI =0.14-0.59) had statistical differences between the observation group and control group,but the difference in other factors had no statistical significance.Conclusion Preoperative obesity,preoperative LDL level and number of removed lymph nodes might be the risk factors for AEF occurrence after esophageal carcinoma operation.
ABSTRACT
Objective:To evaluate the efficacy and safety of cytoreductive surgery (CRS) in conjunction with hyperthermic intra-peritoneal chemotherapy (HIPEC) for treating patients with peritoneal carcinomatosis (PC) from colorectal cancer (CRC). Methods:A total of 62 CRC patients with complication of PC were divided into the CRS group, namely, Group One (n=29, CRS and systemic adju-vant chemotherapy) and the CRS+HIPEC group, namely, Group Two (n=33, CRS+HIPEC). The primary end point of the study was overall survival (OS) and the secondary end point was serious adverse events (SAE). Results:Patients' clinicopathologic characteris-tics, peritoneal carcinomatosis index, and completeness of cytoreduction therapy were well balanced and comparable between the two groups. The median follow-up was 41.9 mo (6.5 mo to 110.0 mo) in Group One and 32.0 mo (10.5 mo to 95.9 mo) in Group Two. The median OS was 8.5 mo (95%CI:4.9 mo to 12.1 mo) in Group One and 14.5 mo (95%CI:11.9 mo to 17.1 mo) in Group Two (P=0.007). Within 30 days after the surgery, SAE occurred in 3 of the 29 patients in Group One, and 9 of the 33 patients in Group Two (P=0.126). Multivariate analysis revealed that HIPEC, CC0-1 score, and chemotherapy over six cycles were the independent factors for OS improvement. Conclusion:The CRS+HIPEC method improves the OS of patients with PC from CRC, suggesting an acceptable safety.
