Objective:To explore the relationship between the morphology of the carotid siphon, its related risk factors, and cerebral blood flow perfusion in patients with arteriosclerotic cerebral small vessel disease (aCSVD), and provide imaging evidence for the etiology of aCSVD.Methods:A total of 130 aCSVD patients hospitalized in the Department of Neurology of the First People′s Hospital of Hefei from March 2022 to June 2024, all of whom underwent multimodal imaging assessments, were enrolled. The baseline data were collected, and the morphology of the carotid siphon was visually evaluated using post-processing of head and neck computed tomography angiography (CTA), which was categorized into U-type ( n=63), C-type ( n=32), and V-type ( n=35). Calcification degree was semi-quantitatively assessed based on transverse CTA images. Cerebral perfusion was measured using magnetic resonance arterial spin labeling. The relationship between different siphon segment morphologies, calcification degrees, their risk factors, and cerebral blood flow perfusion was analyzed using analysis of variance and multinomial Logistic regression. Results:Univariate analysis of the 3 siphon types showed significant differences in low-density lipoprotein cholesterol [U-type (2.44±0.84) mmol/L,V-type (2.21±0.57) mmol/L, C-type (2.89±1.07) mmol/L, F=5.578, P=0.005], calcification degree [Among the 63 cases in the U-type group, 19 cases (30.15%) had mild calcification, 20 cases (31.75%) had moderate calcification, and 24 cases (38.10%) had severe calcification; among the 35 cases in the V-type group, 20 cases (57.14%) had mild calcification, 10 cases (28.57%) had moderate calcification, and 5 cases (14.29%) had severe calcification; among the 32 cases in the C-type group, 12 cases (37.50%) had mild calcification, 14 cases (43.75%) had moderate calcification, and 6 cases (18.75%) had severe calcification; χ2=13.092, P=0.011], and total aCSVD load [modified aCSVD load score: U-type 4.00(1.00, 4.00),V-type 3.00(1.00, 4.00),C-type 2.00(2.00, 4.00), H=9.997, P=0.007]. Multivariate Logistic regression revealed that patients with U-shaped siphons had a significantly higher overall aCSVD load than those with C-shaped siphons, with a regression coefficient of 0.728, and a statistically significant difference ( OR=2.070 ,95% CI 1.026-4.178, P=0.042). Additionally, total brain and white matter cerebral blood flow were decreased in patients with U-type siphons compared to those with C-type and V-type, primarily involving bilateral superior frontal gyri, left orbital frontal gyrus, and left straight gyrus regions (false discovery rate correction, P<0.05). Conclusions:The imaging manifestations of aCSVD are closely related to the shape of the internal carotid artery siphon.The U type siphon is more likely to lead to hemodynamic changes, resulting in decreased global and regional cerebral blood flow, and demonstrating a higher overall burden of aCSVD, which has certain clinical reference value for assessing the etiology of aCSVD.

In addition, gp60 gene was amplified in 10 out of 18 stool samples tested positive for Cryptosporidium. Conclusions Cryptosporidium is widely prevalent in captive-bred ferrets in Jiangsu Province, and Cryptosporidium sp. ferret genotype is the only Cryptosporidium genotype in ferrets.

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 analyze the stability of uncorrected visual acuity (UCVA) of the civil flying cadets after corneal refractive surgery, and to investigate the rationality of the recruitment standard of civil flying cadets after corneal refractive surgery.Methods:The medical records of civil flying cadets who had undergone corneal refractive surgery and participated in physical examination for civil aviation recruitment from October 9th, 2017 to March 10th, 2019 were selected, including surgical methods and preoperative refractive equivalent spherical degree. Those who met the inclusion criteria were followed up for 3 years (once a year), and their UCVA was measured annually and routine ophthalmic examination was performed. Landolt notched ring visual acuity chart was used to measure the UCVA. The civil flying cadets were grouped according to surgical methods, postoperative observation time, preoperative diopter and postoperative remaining corneal thickness. Kruskal-Wallis test and Wilcoxon test were used to compare the changes of UCVA between the recruitment and the follow-ups.Results:A total of 125 qualified flying cadets (240 eyes) treated by corneal refractive surgery were recruited. At the third year of follow-up, 21 eyes (8.75%, 16 cases) of the treated eyes had UCVA <0.9 and 3 eyes (1.25%) had spherical equivalent degree greater than -0.5 D. Compared the UCVA in recruitment with that at the third year of follow-up, the laserin situ keratomileusis group, the observation time <3 years group, the preoperative diopter -3.0-≤-4.5 D group and the residual corneal thickness 460-≤490 μm group showed significant differences ( Z=2.90, 2.82, 2.28, 3.35, P=0.004, 0.005, 0.023, 0.001). Conclusions:The flying cadets treated by corneal refractive surgery could be conditionally recruited if the side influence factors are controlled and their UCVA remains good stability.

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.
