Objective: To determine the association between exposure to entertainment screen content on mobile phones and symptoms of anxiety-depression co-morbidity among college students,so as to provide evidence for mental health interventions. Methods: A baseline survey was conducted from April to May 2019. A total of 1 135 college students were selected from one university each in Shangrao City, Jiangxi Province and Hefei City, Anhui Province using cluster random sampling method. A follow up study was conducted in November 2019, resulting in 1 110 matched valid responses. Self rating questionnaires were used to assess the exposure of entertainment screen content. The Depression Anxiety Stress Scale-21(DASS-21) and the Patient Health Questionnaire-9 (PHQ-9) were used to evaluate the anxiety symptoms, depressive symptoms, and symptoms of anxiety-depression co-morbidity among college students. A multivariate binary Logistic regression model was constructed following initial intergroup comparisons with Chi-square test to determine the association between baseline exposure to mobile entertainment screen content and the risk of symptoms of anxiety depression co-morbidity at baseline and the 6 month follow up. Results: The prevalence rates of symptoms of anxiety-depression co-morbidity among college students were 25.4% and 20.6% at baseline and follow up, respectively.After adjusting for confounding factors such as gender, self rated family economic status and self rated health status, the results of multivariate binary Logistic regression analysis showed that compared with the appropriate exposure level group, the exposure of entertainment screen content on mobile phones at baseline, including frequent exposure to reading( OR =1.65,95% CI =1.14-2.39), occasional exposure to other entertainment screen content ( OR =1.46,95% CI =1.01-2.10)and frequent exposure to other entertainment screen content( OR =1.76,95% CI =1.20-2.60), increased the co-occurrence risk of symptoms of anxiety-depression co-morbidity among college students during the follow up period (all P <0.05). Conclusion Occasional or frequert exposure to mobile entertainment screen content can increase the risk of symptoms of anxiety depression co-morbidity among college students.

Purpose: Our previous study showed that circulating tumor cell (CTC) count combined with gene mutation detection might help differentiate benign and malignant pulmonary nodules (PNs). Herein, we aimed to expand the study cohort and conduct further sequencing analysis. Materials and Methods: Patients with PNs were included, and CTCs were identified before operation. Low-coverage whole-genome sequencing (LC-WGS) and lung cancer-related targeted gene sequencing were performed on CTCs. The diagnostic efficacy was evaluated by receiver operating characteristic (ROC) curve. The differences in CTC counts among subgroups classified by demographic–clinical characteristics were analyzed. LC-WGS–based copy number variation (CNV) analysis and targeted gene mutation analysis were conducted. Results: A total of 172 patients were included. CTC count of 2.5 was identified by the ROC curves as the optimal diagnostic cutoff. The sensitivity and specificity of CTC count for differentiating benign and malignant PNs were 54.2% and 78.6%, respectively. The diagnostic sensitivity and specificity of combined CTC count, radiological nodule type, and any malignant imaging features were 84.7% and 71.4%, respectively. The CTC counts were significantly greater in patients with aggressive tumors, later stage, and spread through air spaces. CTCs from malignant cases had more CNVs than those from benign cases. Conclusion CTC count can be used in identifying malignant PNs. The diagnostic efficacy can be improved if combined with computed tomography imaging characteristics. Further CNV analysis might help differential diagnosis. Greater CTC count might suggest more aggressive tumors. CTC detection can provide important information and guidance for subsequent management of PNs.

Objective: To investigate the longitudinal association between biological rhythm trajectories and the risk of anxiety, depression, and comorbid symptoms among college students, so as to provide a cumulative empirical basis for early psychiatric tracking and mental health warning systems. Methods: Using random cluster sampling method, a baseline survey was conducted from April to May 2019. One comprehensive university and one medical university were selected in Shangrao City, Jiangxi Province, and Hefei City, Anhui Province, respectively. A total of 1 029 first year college students were recruited as study participants, and four waves of longitudinal follow up were carried out over a period of two years. The Self rating of Biological Rhythm Disorder for Adolescents was used to assess college students biological rhythms, and using the dynamic data from the first two follow ups to construct the trajectory of biological rhythm changes. Mental health outcomes (anxiety and depressive symptoms) at the end of the follow up period were assessed using Generalized Anxiety Disorder-7 and Patient Health Questionnaire-9. Multivariable Logistic regression models were employed to evaluate the independent predictive value of distinct lifestyle rhythm trajectories on the detection risk of long term anxiety, depression, and their comorbid symptoms. Results: The prevalence rates of anxiety, depression, and comorbid symptoms among participants were 23.5%, 22.6%, and 16.7%, respectively. Multivariable Logistic regression analysis showed that, after adjusting for confounding factors such as sex, major, smoking, and alcohol consumption, compared with the persistent low risk reference group of overall biological rhythm, the persistent high risk trajectory group of overall assessment had an increased risk of anxiety symptoms( OR=3.87, 95%CI =2.45-6.11), depressive symptoms( OR=3.18, 95%CI =1.98-5.10), and comorbid symptoms( OR=2.43, 95%CI =1.46-4.04)(all P ＜0.05).Among college students in the elevated overall assessment risk group, the risks of anxiety symptoms ( OR=1.97, 95%CI =1.22-3.17), depressive symptoms ( OR=2.13, 95%CI =1.33-3.42), and comorbid symptoms ( OR=1.81, 95%CI =1.07-3.06) were also increased (all P < 0. 05), and the various risks in the group with increased risks were also higher than those in the group with consistently low risks. Conclusions The dynamic deterioration and persistent disruption of college students lifestyle and behavioral rhythms serve as strong early warning indicators for long term anxiety and depressive symptoms. Mental health screening in colleges and universities should incorporate multi timepoint dynamic tracking of behavioral rhythms, and circadian rhythm regulation should be regarded as a core target for group level mental health interventions.

Objective To analyze the predictive value of serum Ficolin-3 combined with National Early Warning Score(NEWS)score in the prognosis of sepsis patients.Methods A total of 120 sepsis patients ad-mitted in the hospital from February 2021 to February 2024 were selected.Serum Ficolin-3 level was detected with samples collected at the time of admission and NEWS score was counted.According to the short-term prognosis,the patients were included in the survival group(n=82)and the death group(n=38).Serum Fico-lin-3 level and NEWS score of all patients were compared.The factors affecting the prognosis of sepsis pa-tients were explored by Multivariate Logistic regression.Results The serum Ficolin-3 and NEWS score in death group were higher than those in survival group(P<0.05).The area under the curve of serum Ficolin-3,NEWS score,and their combined evaluation for predicting the prognosis of sepsis patients were 0.819(95%CI:0.774-0.864),0.764(95%CI:0.714-0.814)and 0.921(95%CI:0.876-0.971),respectively.Arterial oxygen partial pressure(PO2)in the death group was lower than that in the survival group(P<0.05),se-quential organ failure assessment(SOFA)score at admission,acute physiology and chronic health evaluation(APACHEⅡ)score at admission,the proportion of acute kidney injury after admission and diabetes were higher than those in the survival group(P<0.05).Multivariate Logistic regression analysis showed that PO2<70.30 mmHg(OR=2.399,95%CI:1.182-4.867),SOFA score≥7 points at admission(OR=2.479,95%CI:1.306-4.706),APACHEⅡ score≥24 points(OR=2.557,95%CI:1.355-4.826),serum Ficolin-3≥4.16 mg/L(OR=3.421,95%CI:1.750-6.688),NEWS score≥7.15 points(OR=2.921,95%CI:1.661-5.137)were factors affecting the prognosis of sepsis patients(P<0.05).Conclusion High level of serum Ficolin-3 and high NEWS score are closely related to poor short-term prognosis of sepsis patients,and the combination of Ficolin-3 level and NEWS score could effectively improve the predictive value of short-term prognosis of sepsis patients.

Objective To investigate the effect of intravenous lidocaine on postoperative fatigue syndrome(POFS)in patients undergoing laparoscopic resection for gastric carcinoma.Methods A total of 80 patients who underwent elective laparoscopic resection for gastric carcinoma at Xuzhou Central Hospital between September 2023 and June 2024 were enrolled.Inclusion criteria included age 18～75 years,ASA physical status classificationⅠ～Ⅲ,body mass index(BMI)of 18.5～27.9 kg/m2,preoperative Christensen score≤4,and estimated operation time≤4 hours.Patients were randomly allocated into either the lidocaine group(Group L)or the saline group(Group C)using a random number table,with 40 patients in each group.Group L received an intravenous infusion of lidocaine at a dose of 1.5 mg·kg?1 over 15 minutes,initiated 30 minutes before anesthesia induction.If no adverse reactions occurred,lidocaine was maintained at a rate of 1.5 mg/(kg·h)throughout the surgery until its conclusion.Group C received an equivalent volume of normal saline administered in the same manner.The Christensen score and Visual Analogue Scale(VAS)scores were recorded on postoperative days 1,3,5,and 7,and the time-weighted average(TWA)of the Christensen score was calculated.Postoperative inflammatory markers were measured,and additional outcomes including extubation time,post-anesthesia care unit(PACU)stay duration,postoperative nausea and vomiting(PONV),consumption of rescue analgesics,time to first flatus and defecation,and length of hospital stay were also documented.Results Compared with Group C,the TWA of the Christensen score in Group L decreased by 0.44 points(95％CI:0.11～0.76;P<0.05).The VAS scores were significantly lower in Group L on postoperative days 1 and 3(P<0.05).Levels of IL-6 and TNF-α at the end of surgery and 24 hours after surgery were also lower in Group L(P<0.05).The time to first flatus and defecation was significantly shorter in Group L(P<0.05).There were no significant differences between the two groups regarding extubation time,PACU stay duration,incidence of PONV,postoperative consumption of remedial analgesic drugs,or length of hospital stay(P>0.05).Conclusion Intravenous lidocaine may improve POFS in patients following laparo-scopic resection for gastric carcinoma by attenuating inflammatory responses,alleviating pain,and facilitating gastrointestinal function recovery,while maintaining a favorable safety profile.

Objective To investigate the effect of orthosis design parameters on correction of scoliosis and orthosis-trunk interface pressure.Methods A finite element model of scoliosis was constructed to simulate the assembly effect of the orthosis.The orthosis was divided into four loading areas(left rib,right rib,anterior-left and posterior-right area)to simulate six modification conditions.In Models 1,2 and 3,a fixed modification of 20 mm was applied on the anterior left and posterior right areas,while the displacement loads of 20,25 and 30 mm were applied on both the left rib and right rib areas.In Models 4,5 and 6,a fixed modification of 25 mm was applied on left rib and right rib areas,with the displacement loads of 15,20 and 25 mm applied on both anterior left and posterior right areas.The Cobb angle,apical vertebral rotation(AVR)and interface pressure were calculated.Results The correction of Cobb angle in Models 1,2 and 3 was 8.94°,15.62° and 17.91°,respectively,with AVR correction of 7.53°,6.69° and 5.87°,respectively.In Models 4,5 and 6,the correction of Cobb angle was 14.55°,15.62° and 16.09°,with AVR correction of 5.25°,6.69° and 8.63°,respectively.In Model 6,the correction rate of Cobb angle and AVR was 45.48%and 41.22%,respectively,with a maximum pressure of 26.51 kPa on orthosis-trunk interface,achieving the most significant outcome.Conclusions The modification of orthosis has a significant effect on the correction of Cobb and AVR angles.The loading on the left rib and right rib areas mainly affect the Cobb angle,while the loading on the anterior left and posterior right areas mainly affect the spinal axial-rotation.A modification of 25 mm on all loading areas achieves the optimal spinal correction.This study provides the quantitative data for orthosis design.

Objective:To explore the impact of childhood trauma on drug relapse tendency, as well as the mediating role of post-traumatic stress disorder (PTSD).Methods:From March to May 2017, a total of 403 compulsory drug rehabilitation personnel were selected for a cross-sectional study and then were investigated by the general demography scale, drug relapse risk scale, childhood trauma questionnaire (CTQ), and PTSD checklist for DSM-5(PCL-5).SPSS 27.0 software and PROCESS 4.1 macro program were used for correlation analysis, regression analysis and Bootstrap-based mediation analysis.Results:The scores of negative emotions subscale of drug relapse risk scale, emotional abuse and emotional neglect subscales of CTQ had no significant gender differences(all P>0.05).There were gender differences in relapse tendency, childhood trauma, and PTSD total scores as well as other dimensions ( t/ Z=2.08-4.67, all P<0.05).There were pairwise positive correlations among the total score of the drug relapse risk scale(31.68±9.79), CTQ(39.90±12.13), and PCL-5(11(3, 24)) for compulsory isolation and rehabilitation personnel ( r=0.28, 0.36, 0.37, P<0.05).After controlling for gender, childhood trauma could significantly and positively predict drug relapse tendency( β=0.34, t=7.24, P<0.01), and PTSD played a mediating role between childhood trauma and drug relapse tendency, with the indirect effect of 0.11(95% CI=0.06-0.16). Conclusion:Childhood trauma can affect drug relapse tendency directly, and indirectly through PTSD.
