Objective: To explore the network structure of eating behaviors with anxiety, depression and perceived stress in adolescents, so as to provide a basis for effective prevention and intervention of eating behavior problems and negative emotions in adolescents. Methods: Based on the Psychology and Behavior Investigation of Chinese Residents (2021) database, the study was conducted among 3 087 adolescents. Sakata Eating Behavior Scale Short From(EBS-SF) was used to investigate their eating behaviors. The Patient Health Questionnaire-9(PHQ-9), Generalized Anxiety Disorder Scale-7 Item(GAD-7), and Perceived Stress Questionnaire-3 Item (PSQ-3) were used to evaluate their depression, anxiety and perceived stress. Network analysis method was applied to construct a network of eating behaviors and negative emotional symptoms among adolescents, so as to evaluate the centrality, bridge strength, stability and accuracy of each item. Results: The total scores of eating behaviors, depression,anxiety and stress perception in adolescents were 17.41±4.53,6.95±6.08,4.86±5.03,9.34±3.80,respectively. The symptom with the highest intensity and expected impact was "I am only satisfied when I buy more food than I need", with a node intensity and expected impact value of 4.37. The nodes Depression and Anxiety were the most closely connected(weight=0.87). There were no statistically significant differences in the network structure( M =0.13,0.11) and network connection strength(female and male:4.16,4.06, s =0.10;urban and rural areas:4.08,4.07, s =0.01) between different sexes and residents ( P >0.05). Conclusion The negative impact of comorbidities such as anxiety, depression, perceived stress and eating behaviors among adolescents can be reduced through targeted prevention and intervention of core symptoms and bridging symptoms.

Objective: To investigate the knowledge, attitude and practice of infectious disease prevention and control among primary and middle school students in Gongshu District, Hangzhou City, so as to provide the evidence for implementing health education on infectious disease prevention and control in schools. Methods: Students from 12 primary and middle schools in Gongshu District were selected using a random cluster sampling method. Basic information, knowledge, attitude and practice of infectious disease middle and control were collected through questionnaire surveys. Influencing factors of practice of primary and middle school students' infectious disease prevention and control were analyzed using multivariable logistic regression model. Results: A total of 3 439 primary and middle school students were surveyed, including 1 717 boys (49.93%) and 1 722 girls (50.07%). There were 1 237 primary school students (35.97%), 1 092 junior high school students (31.75%), and 1 110 senior high school students (32.28%). The awareness of infectious disease prevention and control knowledge, the percentage of attitude towards infectious disease prevention and control, and the percentage of practice towards infectious disease prevention and control were 73.22%, 96.83%, and 60.19%, respectively. Multivariable logistic regression analysis revealed that girls (OR=1.460, 95%CI: 1.265-1.685), those who had received health education on infectious disease prevention (OR=2.088, 95%CI: 1.656-2.632), those with adequate knowledge (OR=2.129, 95%CI: 1.816-2.496), and those with positive attitude (OR=4.320, 95%CI: 2.683-6.957) were more likely to form practice for the prevention and control of infectious disease. Conversely, senior high school students (OR=0.667, 95%CI: 0.561-0.794) and those with poor self-rated health status (OR=0.678, 95%CI: 0.495-0.930) were less likely to form practice for the prevention and control of infectious disease. Conclusions The attitude towards infectious disease prevention and control among primary and middle school students in Gongshu District is relatively high, but their awareness and practice are low. It is recommended to strengthen health education on infectious disease prevention and control knowledge in a targeted manner to promote the formation of prevention and control practice among senior high school students and primary and middle school students who self-assess their health status as poor.

Objective: To investigate the association between dietary quality and overweight / obesity among primary school students, so as to provide a basis for the prevention and control of childhood obesity. Methods: In September 2022, third-grade students from six primary schools in Ningbo City, Zhejiang Province were selected by a random cluster sampling method. Data on gender, age, height, and weight were collected through questionnaire surveys and physical examinations. Body mass index (BMI) was calculated, and overweight and obesity were determined using gender- and age-specific BMI cut-off points. The Chinese dietary quality questionnaires was administered to assess the intake of health-promoting and restricted foods over the past 24 hours, thereby evaluating overall dietary quality. A multivariate logistic regression model was used to analyze the association between dietary quality and overweight / obesity among primary school students. Results: A total of 1 375 primary school students were included, comprising 722 (52.51%) boys and 653 (47.49%) girls, with a mean age of (8.47±0.30) years. Among them, 165 (12.00%) were overweight and 171 (12.44%) were obese. The score for health-promoting foods was (4.29±2.27) points. The median score of restricted foods was 2.00 (interquartile range, 3.00) points. The total dietary quality score was (10.84±2.42) points. Multivariable logistic regression analysis indicated that the restricted food score was positively associated with overweight (OR=1.073, 95%CI: 1.002-1.148), while the total dietary quality score was negatively associated with overweight (OR=0.911, 95%CI: 0.851-0.976). However, no statistically significant associations were observed between the health-promoting food score and overweight or obesity (both P>0.05), nor between the restricted food score or total dietary quality score and obesity (both P>0.05). Conclusion A higher intake of restricted foods was associated with an increased risk of overweight, while a better dietary quality was associated with a decreased risk of overweight among primary school students.

In order to accurately capture the respiratory muscle movement and extract the synchronization signals corresponding to the breathing phases, a comprehensive signal sensing system for sensing the movement of the respiratory muscle was developed with applying the thin-film varistor FSR402 IMS-C07A in this paper. The system integrated a sensor, a signal processing circuit, and an application program to collect, amplify and denoise electronic signals. Based on the respiratory muscle movement sensor and a STM32F107 development board, an experimental platform was designed to conduct experiments. The respiratory muscle movement data and respiratory airflow data were collected from 3 healthy adults for comparative analysis. In this paper, the results demonstrated that the method for determining respiratory phase based on the sensing the respiratory muscle movement exhibited strong real-time performance. Compared to traditional airflow-based respiratory phase detection, the proposed method showed a lead times ranging from 33 to 210 ms [(88.3 ± 47.9) ms] for expiration switched into inspiration and 17 to 222 ms [(92.9 ± 63.8) ms] for inspiration switched into expiration, respectively. When this system is applied to trigger the output of the ventilator, it will effectively improve the patient-ventilator synchrony and facilitate the ventilation treatment for patients with respiratory diseases.

OBJECTIVE: To evaluate the effectiveness and safety of minimally invasive treatment for bilateral tibial plateau fractures using the double reverse traction reducer. METHODS: The clinical data of 4 patients with bilateral tibial plateau fractures who met the selection criteria and treated between January 2016 and April 2024 were retrospectively analyzed. The cohort included 3 males and 1 female, aged 30-65 years (mean, 52.5 years). Injury mechanisms comprised traffic accidents (2 cases) and falls (2 cases). According to the Schatzker classification, 2 limbs were type Ⅱ and 6 were type Ⅵ. The time from injury to surgery ranged from 5 to 9 days (mean, 7 days). All patients underwent minimally invasive reduction using the double reverse traction reducer. Surgical duration, intraoperative blood loss, and hospitalization time were recorded. Functional outcomes were assessed at last follow-up using the Hospital for Special Surgery (HSS) knee score and range of motion (ROM), while fracture reduction quality was evaluated using the Rasmussen radiological score. RESULTS: All 4 patients successfully completed the procedure without conversion to open reduction. The total mean operation time was 80.25 minutes (range, 73-86 minutes), with a mean total intraoperative blood loss of 132.5 mL (range, 100-150 mL). The mean hospitalization time was 13.5 days (range, 11-16 days). All incisions healed primarily without neurovascular complications. X-ray film at 1 day after operation confirmed satisfactory reduction and articular surface alignment. Follow-up time ranged from 12 to 26 months (mean, 17.0 months). Fractures achieved clinical union at an average of 13 weeks (range, 12-16 weeks). No complication, such as deep vein thrombosis, joint stiffness, post-traumatic arthritis, or implant failure, was observed. At last follow-up, the mean HSS score was 92.9 (range, 90-97), mean knee ROM was 128.1° (range, 115°-135°), and mean Rasmussen radiological score was 16.4 (range, 15-19), with 2 limbs rated as excellent and 6 as good. CONCLUSION The double reverse traction reducer facilitates minimally invasive treatment of bilateral tibial plateau fractures with advantages including minimal trauma, shorter surgical duration, precise reduction, and fewer complications, effectively promoting fracture healing and functional recovery of the knee joint.

Objective To investigate the effect of PIAS3 on glucose fluctuation-induced oxidative stress and mito-chondrial dysfunction in rat cardiomyocytes.Methods H9c2 were cultured in vitro,and divided into normal glucose control group(Control),mannitol-induced osmotic pressure control group(MG),constant high glucose group(HG),intermittent hyperglycemia group(IHG),IHG+siRNA NC group,and IHG+PIAS3 siRNA group.Cell proliferation was assessed using CCK-8 assay.LDH release,MDA and GSH levels,as well as SOD activity,were detected using corresponding kits.Mitochondrial membrane potential was evaluated via JC-1 staining combined with flow cytometry.ROS levels in cells and mitochondria were determined using DCFH-DA and MitoSOX staining,re-spectively.Protein expression of PI3K,p-PI3K,AKT,and p-AKT was analyzed by Western blot.Results Com-pared with the control group,intermittent hyperglycemia promoted oxidative stress and mitochondrial dysfunction,significantly upregulated PIAS3 expression(P＜0.001)and downregulated p-PI3K and p-AKT protein levels(P＜0.001).Knockdown of PIAS3 significantly alleviated oxidative stress and mitochondrial dysfunction induced by glucose fluctuations,and increased p-PI3K and p-AKT protein levels(P＜0.001).Conclusions Knockdown of PIAS3 may alleviate glucose fluctuation-induced oxidative stress and mitochondrial dysfunction in ratcardiomyocytes by activating the PI3K/AKT signaling pathway.

OBJECTIVE: To investigate the clinical characteristics and genetic etiology of a male with a normal phenotype and SRY gene-positive 46,XX/46,XY tetrazoospermia chimerism. METHODS: A male patient with an abnormal peripheral blood chromosomal karyotype detected at the Infertility Center of Taizhou Hospital of Zhejiang Province on December 2, 2013 was selected as the study subject. Peripheral venous blood samples were collected from the proband and his family members, together with a semen sample from the proband. Chromosomal karyotype analysis, red blood cell blood group identification, chromosomal microarray analysis (CMA), fluorescence in situ hybridization (FISH), sex-determining region Y (SRY) gene detection, and short tandem repeat (STR) microsatellite marker analysis were performed on the peripheral venous blood sample from the proband. Routine semen analysis, sperm FISH, and STR testing were also conducted. STR verification was performed on both parents. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: k20201009). RESULTS: The proband, a 37-year-old male, had normal secondary sexual characteristics and external genitalia development. The chromosomal karyotype of his peripheral blood sample was 46,XX[94]/46,XY[6]. ABO blood group typing was positive for Rh(D) type O and negative for Rh(D) type A, indicating the presence of two red blood cell populations. CMA result was arr[GRCh37](1-22)×2,(XX)×1. Autosomal and X chromosome SNP genotypes were BB-BB, AB-AB, and AA-AA, making it impossible to identify homozygous/heterozygous chimerism. FISH detection of interphase nuclei showed nuc ish XX[92]/XY[8]. Testing of the SRY gene was positive. STR analysis showed a single X peak (no Y peak) at the AMEL locus, 10/12 at the Penta D locus, and no third allele at other loci. Routine semen analysis were normal. Sperm FISH detection showed haploid nuclei nuc ish X[53]/Y[47]. Sperm STR analysis revealed an X/Y bimodal distribution at the AMEL locus and a 9/14 distribution at the Penta D locus, with no third allele observed at other loci. Above results suggested that the proband's blood and germ cell lines had originated from a heterozygous chimera formed by the fusion of two different zygotes. CONCLUSION Combined genetic techniques confirmed that the proband's peripheral blood AMEL genotype is X/X, while the sperm is X/Y. The Penta D locus showed a bi-allelic heterozygous pattern of 10/12 in the peripheral blood sample and 9/14 in the sperm sample, suggesting that the proband is a tetrazygotic chimera resulted from the fusion of 46,XX/46,XY zygotes.
