Objective:
To investigate abnormal spinal curvature among primary and secondary school students in Sichuan Province, so as to provide evidence for scientific prevention.
Methods:
Using a stratified cluster random sampling method, a total of 210 713 students of grade 4 to grade 12 from 21 cities (prefectures) in Sichuan Province were selected for spinal curvature screening and questionnaire survey from September to November 2022. Chi-square test and multivariate Logistic regression model were used to analyze the influencing factors of abnormal spinal curvature.
Results:
The detection rate of abnormal spinal curvature was 3.42%, with urban areas (4.54%) higher than that in suburban areas(2.57%), girls (3.86%) higher than that in boys(2.98%), high school students (4.70%) higher than that in middle school students (3.80%) and elementary school students(2.21%), the differences were statistically significant ( χ 2=606.96, 123.81, 645.24, P <0.01). Multivariate Logistic regression analysis showed that urban area, junior and senior high school, girl, carrying backpack on one shoulder, desks and chairs adjusted for student height less than ≤1 time every school year, moderate-to-vigorous physical activity less than 1 h per week, and indoors sedentary time more than 10 h/d were positively associated with abnormal spinal curvature ( OR=1.72, 1.75, 1.87, 1.26, 1.09, 1.07, 1.10, 1.25 , P <0.05).
Conclusion
The detection rate of abnormal spinal curvature of primary and secondary school students may be affected by the urbanicity, educational stage as well as gender in Sichuan Province. More attention should be paid to urban high school girls, and targeted strategies should be explored to reduce the incidence of abnormal spinal curvature.

Objective:To evaluate the effect of self-made lithotomy heating mask on intraoperative and postoperative body temperature and short-term postoperative outcome indicators in patients undergoing radical resection of rectal cancer.Methods:Using the method of quasi experimental research design, 100 patients with open rectal cancer in Ningbo Huamei Hospital of the University of Chinese Academy of Sciences from February to July 2021 were selected as the research objects. The patients were divided into experimental group and control group with 50 cases in each group. The control group was kept warm by routine methods, and the experimental group was kept warm by self-made lithotomy heating hood. The changes of core temperature at different time points before, during and after operation were compared between the two groups. The incidence of accidental hypothermia and shivering, the recovery time of anesthesia, and the incidence of various complications within 48 hours after operation were compared between the two groups after operation from the beginning of the operation to 6 hours after returning to the ward.Results:From 30 minutes after anesthesia to 3 hours after entering the ward, the core temperatures of the experimental group at 10 time points were higher than that of the control group, and the differences were statistically significant ( t values were 3.48-37.30, all P<0.01). From the beginning of surgery to 6 h after returning to the ward, the incidence of perioperative accidental hypothermia in the experimental group was 2% (1/50), lower than 24% (12/50) in the control group, and the difference was statistically significant ( χ2=11.06, P<0.05) . The number of cases of shivering in the experimental group was 10, lower than that in the control group of 22, the difference was statistically significant ( χ2=6.62, P<0.05) . The recovery time, extubation time and stay time in anesthesia recovery room of the experimental group were (8.44 ± 2.83), (13.05 ± 4.72), (74.51 ± 11.82) min, which were shorter than those of the control group (15.35 ± 2.09), (17.62 ± 3.28), (89.14 ± 9.19) min, and the difference was statistically significant ( t=-13.89, -5.62, -6.91, all P<0.01). The number of cases of agitation, delirium and nausea and vomiting in the experimental group was 3, 1 and 2 respectively, which was lower than 13, 7 and 8 in the control group, and the difference were statistically significant ( χ2=7.44, 4.89, 4.00, all P<0.05). There was no significant difference in the incidence of adverse cardiac events between the two groups ( P>0.05). Conclusions:The application of self-made lithotomy heating mask in open rectal cancer surgery can effectively improve the risk of hypothermia at different time points during and after surgery, reduce the incidence of shivering, restlessness, postoperative nausea, vomiting and delirium, shorten the time of awakening and extubation, and prevent postoperative complications. It has practical value in clinic.

Purpose:
This study aimed to develop a nomogram for predicting pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (CRT) in patients with esophageal squamous cell carcinoma (ESCC) by integrating hematological biomarkers and clinicopathological characteristics.
Materials and Methods:
Between 2003 and 2017, 306 ESCC patients who underwent neoadjuvant CRT followed by esophagectomy were analyzed. Besides clinicopathological factors, hematological parameters before, during, and after CRT were collected. Univariate and multivariate logistic regression analyses were performed to identify predictive factors for pCR. A nomogram model was built and internally validated.
Results:
Absolute lymphocyte count (ALC), lymphocyte to monocyte ratio, albumin, hemoglobin, white blood cell, neutrophil, and platelet count generally declined, whereas neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) increased significantly following neoadjuvant CRT. After surgery, 124 patients (40.5%) achieved a pCR. The pCR group demonstrated significantly more favorable survival than the non-pCR group. On multivariate analysis, significant factors associated with pCR included sex, chemotherapy regimen, post-CRT endoscopic finding, pre-CRT NLR, ALC nadir during CRT, and post-CRT PLR, which were incorporated into the prediction model. The nomogram indicated good accuracy in predicting pCR, with a C-index of 0.75 (95% confidence interval, 0.71 to 0.78).
Conclusion
Female, chemotherapy regimen of cisplatin/vinorelbine, negative post-CRT endoscopic finding, pre-CRT NLR (≤ 2.1), ALC nadir during CRT (> 0.35 ×109/L), and post-CRT PLR (≤ 83.0) were significantly associated with pCR in ESCC patients treated with neoadjuvant CRT. A nomogram incorporating hematological biomarkers to predict pCR was developed and internally validated, showing good predictive performance.

Objective We aimed to analyze the clinical efficacy and treatment-related complications in patients with T4besophageal squamous cell carcinoma (SCC) who received concurrent CRT,and to explore the potential prognostic factors related to survival. Methods Between 2010 and 2015,143 patients with T4b esophageal SCC treated with CRT were analyzed, including 71% patients with trachea and/or bronchus invasion and 44% patients with aorta and/or large vessel invasion. The median radiation dose was 60 Gy ( range, 44-68 Gy ) with conventional fractionation, including 69 patients ( 48%) treated with three-dimensional conformal radiotherapy and 74 patients ( 52%) treated with intensity-modulated radiotherapy. All patients received concurrent platinum-based chemotherapy during radiotherapy. Kaplan-Meier method was used to analyze the survival,the log-rank test was used to examine group differences,and the Cox regression model was used for multivariate analysis. Results The median overall survival ( OS) time for the whole cohort was 12. 2 months. The 2-and 3-year OS rates were 34% and 29%,respectively. A total of 51 patients experienced ≥2 severe non-hematological complications,including 42 esophageal fistula,6 pneumonia,and 3 esophageal hemorrhage. Patients with severe complications showed significantly worse survival than those without complications (6. 9 months vs.20. 4 months,P<0. 01).Multivariate analysis revealed that TNM stage and severe complications were independent prognostic factors for OS. Conclusions Patients with T4b esophageal SCC who received CRT showed satisfactory survival but with high risk of severe complications. Therefore,prevention and treatment of severe complications is the key to improve efficacy.
