Objective: To understand the changing trends and related factors of knowledge, attitude and practice (KAP) regarding the three major infectious diseases (acquired immunodeficiency syndrome, tuberculosis, hepatitis B) among freshmen in Jiangsu from 2019 to 2022, so as to provide a reference basis for the health education of infectious diseases in schools. Methods: From 2019 to 2022, a total of 33 944 freshmen from 20 universities in Jiangsu Province were randomly selected for four consecutive years to investigate their KAP levels online through self designed questionnaires on three major infectious diseases. The multiple linear regression model was used to analyze the changing trends of students KAP levels of the three major infectious diseases, and to explore the influencing factors of KAP. Results: From 2019 to 2022, the knowledge scores(18.0±3.1,18.4±3.2,18.7±3.2,18.8±3.2), related to the three major infectious diseases showed an upward trend ( F=436.50, P <0.01), and the positive attitude reporting rates were 81.77%, 81.46%, 82.68% and 81.74%, respectively. The reporting rates of positive practice were 80.11%, 79.25%, 79.08 % and 79.04%, respectively. Multiple linear regression showed that school type, parental education level, mother s occupation, average income per person in family and living arrangements during high school all had an impact on the knowledge ( β = -1.510 -0.559), attitudes ( β =-0.043-0.065) and practice ( β =-0.028-0.027) of the three major infectious diseases ( P < 0.05 ). The family residence areas only affected the reporting rate of positive attitude scores ( β =0.002-0.065), and whether only children or not affected the reporting rate of positive practice scores ( β =0.009)( P <0.05). The knowledge score showed an upward trend ( β= 0.297, P <0.01), the positive attitude reporting rate showed no statistically significant change ( β=0.001, P =0.22), and the positive practice reporting rate showed a downward trend ( β=-0.005, P <0.01). Conclusions Freshman in Jiangsu Province from 2019 to 2022 have shown a separation in KAP scores regarding the three major infectious diseases. Targeted measures should be taken to improve their health practice level.

OBJECTIVE: To explore the efficacy and safety of human epidermal growth factor gel in the treatment of pin tract infections after surgery in patients with severe spinal deformity. METHODS: A retrospective case-control study was conducted to analyze the clinical data of 26 patients with pin tract infections after skull-pelvic ring traction for severe spinal deformity admitted from February 2019 to May 2022. Among them, 11 were male and 15 were female;the age ranged from 18 to 31 years, with an average of (24.1±4.3) years;the Cobb angle ranged 80.3° to 120.7°, with an average of (88.6±10.2)°;there were 52 iliac traction pins, 104 pin tract openings, and 38 pin tract infections. According to the Checketts-Otterbum classification, there were 11 infections of gradeⅠ, 13 infections of gradeⅡ, 10 infections of grade Ⅲ, and 4 infections of grade Ⅳ. The patients were divided into the conventional dressing change group (13 cases) and the growth factor group (13 cases) by coin flipping. Clinical efficacy was evaluated by recording the visual analogue scale(VAS) score during dressing change, duration of dressing change, cost of dressing change, positive rate of bacterial culture, wound improvement rate, and wound improvement time. RESULTS: There were no statistically significant differences in VAS or duration of dressing change between the two groups (P>0.05). The cost of dressing change was (800.0±59.5) yuan in the conventional dressing change group and (1 179.5±80.9) yuan in the growth factor group, with a statistically significant difference (P<0.05). There was no statistically significant difference in the positive rate of bacterial culture between the two groups (P>0.05). In the conventional dressing change group, within 20 pin tract infections, 2 infections achieved wound healing, 7 infections showed improvement, and 11 infections were ineffective;in the growth factor group, within 18 pin tract infections 5 infections achieved wound healing, 8 infections showed improvement, and 5 infections were ineffective, with a statistically significant difference between the two groups (P<0.05). The wound healing time was (22.8±4.9) days in the conventional dressing change group and (14.2±2.5) days in the growth factor group, with a statistically significant difference (P<0.05). No complications occurred in either group. CONCLUSION The application of human epidermal growth factor gel in the treatment of pin tract infections after skull-pelvic ring surgery in patients with severe spinal deformity is easy to operate, does not increase patient pain, and has significant efficacy. It shortens wound healing time, effectively promotes wound healing, and has good safety and high cost-effectiveness.

Objective: To understand the trends and associated factors of tuberculosis knowledge and behavior among freshmen from Jiangsu Province, 2019 to 2022, so as to provide theoretical support for the popularization of tuberculosis knowledge and the prevention and control of tuberculosis in universities. Methods: From 2019 to 2022, a total of 33 944 freshmen from 20 universities in Jiangsu Province were selected by stratified random sampling, and tuberculosis knowledge and behavior were surveyed online using a selfdesigned questionnaire. Oneway variance trend test and multiple linear regression analysis were used to analyze the trend of knowledge and behavior levels, and a multiple linear regression model was used to analyze the influencing factors. Results: The overall awareness rate of tuberculosis among freshmen from Jiangsu Province was 90.6%, and the overall awareness rates from 2019 to 2022 were 88.4%, 90.4%, 91.7%, and 91.8%, respectively. The overall behavioral accuracy rate was 92.3%, with the annual rates from 2019 to 2022 being 91.8%, 92.3%, 92.7%, and 92.4%, respectively. Both the awareness rate and accuracy behavior rate increased annually (F=216.67, 11.75, P<0.01). The multiple linear regression analysis showed that school type, ethnicity, fathers educational level, mothers educational level, mothers occupation, family per capita monthly income, and living arrangement in high school affected both personal knowledge awareness rate and personal behavioral accuracy rate (β=-0.047-0.035, P<0.01), while region, gender, family residence, and being an only child only affected behavioral accuracy rate (β=-0.003-0.032, P<0.05). Conclusions The tuberculosis knowledge and behavior levels of freshmen from Jiangsu Province have been increasing by year. Targeted health education should be carried out based on the relevant influencing factors to further enhance the tuberculosis prevention and control literacy.

Objective:To investigate alterations in functional connectivity network and brain function activity in childhood absence epilepsy (CAE) based on neuromagnetic signals by using multi-frequency magnetoencephalography.Methods:Twenty-five drug-naive children diagnosed with CAE from the Affiliated Brain Hospital of Nanjing Medical University and the Affiliated Children′s Hospital of Nanjing Medical University during October 2022 and March 2024 and 25 healthy controls matched for age and sex from community were recruited in this cross-sectional study. The interictal data, ictal data of CAE and healthy control children were collected using a CTF-275 channel magnetoencephalography system. Corrected amplitude envelope correlation was used to construct functional connectivity network, and network-based statistics were used to compare network differences between groups. Relative power spectral density was used to describe the distribution characteristics of whole-brain spectral power. Nonparametric permutation tests were conducted 1 000 times to compare spectral power differences between groups.Results:In terms of functional connectivity, significant increases in network activity were observed in the low-frequency bands (δ, θ) during interictal periods in children with CAE. A sub-network with significantly increased functional connectivity, including key nodes of the default mode network, was observed in the δ band. Compared with interictal periods, functional connectivity in the δ band decreased during absence seizures in children with CAE, while connectivity in the mid-to-high-frequency bands (α-γ2) increased. In terms of spectral power, children with CAE during interictal periods exhibited widespread magnetic source activation in the δ band, activation in parts of the parietal and occipital lobes in the θ band, and significantly decreased magnetic source intensity in most areas of the parietal, occipital, and temporal lobes in the α-γ2 band. Compared with interictal periods, children with CAE during absence seizures exhibited widespread magnetic source activation in the δ band, and significantly decreased activation in the θ-γ2 band. According to the magnetic source distribution map, during absence seizures, the frontal lobe replaced the parieto-occipital region in cortical activation in the α band.Conclusion:In the analysis of functional network and spectral power based on multi-frequency neuromagnetic signals, the network pattern and magnetic source activation of children with CAE during interictal periods were significantly different from those of healthy children, and there were characteristic changes in neuromagnetic signals during consciousness impairment caused by absence seizures in children with CAE.

Objective: To understand health literacy and associated factors of freshmen from Jiangsu Province, and to provide reference for youth health education. Methods: From 2017 October to 2018 October, a total of 15 602 college freshman were randomly selected from 20 universities in Jiangsu Province via stratified cluster sampling method. Structural questionnaires were used to investigate the status of health literacy. The χ 2 test and multivariate Logistic regression model were used to analyze the influencing factors of health literacy. Results: The health literacy level of college freshmen from Jiangsu Province was 20.2%, among which the literacy levels of knowledge, behavior and skills were 23.0%, 30.7% and 31.5% respectively. The literacy levels of the six public health issues, including safety and first aid, scientific health attitude, knowledge of prevention and treatment of infectious diseases, health information, basic health care, and prevention and treatment of chronic diseases, from high to low, were 72.8%, 58.7%, 28.5%, 28.2%, 20.3% and 15.9%, respectively. Multivariate Logistic regression analysis has showed that students from undergraduate colleges(OR=2.77, 95%CI=2.47-3.11), urban areas(OR=1.20, 95%CI=1.07-1.34), or southern Jiangsu regions(OR=1.10, 95%CI=1.00-1.22), being the only child(OR=1.13, 95%CI=1.03-1.25), higher maternal education level (OR=1.53, 95%CI=1.30-1.79), having both parents(OR=1.16, 95%CI=1.00-1.34), reported higher level of health literacy. Conclusion The three aspects and six dimensions of health literacy of college freshmen were unbalanced. Health literacy is a shared function of multiple factors including society, family, and individuals. It is essential to promote health education through more efforts on key issues, in order to effectively elevate the health literacy level of adolescent students.

OBJECTIVE: To choose the disease-causing gene in a Chinese pedigree with ankylosing spondylitis (AS) by whole-exome sequencing (WES), and provide theory basis for mechanism of disease. METHODS: Clinical data of AS pedigree were collected, including 2 males, the age were 48 and 18 years old, the course of disease were 23 and 4 years. Whole blood genomic DNA of AS was extracted to perform whole exome sequencing, the results were compared with human databases, common variations which had been reported were wiped out, then non synonymous single nucleotide variants(SNVs) from the family members were combined, and candidate genes was selected initially. RESULTS: Totally 80 G data was obtained from AS family with high quality.By comparing results between patient and normal subject, and filtering with number of biological database, the result showed heterozygous mutation of JAK2 gene 12 exon c.1709 A>G (p.Tyr570Cys) may be the potential disease-causing gene. The variant c.1151T>C of MUC3A gene may be one of the causes of intestinal symptoms in the family members. CONCLUSION It is feasible to find t candidate gene mutations of AS by Exon sequencing. The mutation c.1709 A>G in gene JAK2 identified by whole exome sequencing might be the pathogenic mutation in this AS pedigree.

OBJECTIVE: To explore surgical methods and clinical effects of three different types of mini skin flap transplantation for repairing finger soft tissue with bone defect. METHODS: Thirty-three patients with finger soft tissue or bone defect were treated from December 2014 to October 2016, including 24 males and 9 females aged from 21 to 52 years old with an average of (36.42±5.70) years old, and soft tissue defect area ranged from 1.3 cm×1.8 cm to 2.3 cm×4.2 cm. According to damage degree, nature and patients' options, 15 finger of 15 cases were adopted retrograde dorsal metacarpal artery perforators fascia flap, 10 fingers of 9 cases were treated with free foot artery descending branch wrist skin flap, 9 fingers of 9 cases were treated with free the second toe details phalanges compound flap. Survival rate, postoperative complications and finger function assessed by Dargan functional criteria at the latest follow up were observed. RESULTS: All flaps were survived, both of donor site and recipient site were without deep infected. The donor site of one patient occurred necrotic, and the distal donor site of one patient occurred surface necrotic, then healed by active dressing change. All patients were followed up from 6 to 16 months with an average of(8.34±1.28) months. Two points of finger recognition were restored between 8 and 12 mm with an average of (8.84±0.43) mm, and the appearance, texture and sensory functions of skin flap were restored. No obvious complications were observed on the donor site. According to Dargan function evaluation of finger joints, 18 patients got excellent results, 14 moderate and 1 good. CONCLUSIONS Three kinds of mini skin flap could receive good results in repairing soft tissue of finger or bone defect. Reverse dorsal metacarpal artery perforator fascia flap is not necessary with anastomosing blood vessels and has advantages of safe, simple and high survival rate. Descending branch of superior cutaneous branch of free ulnar artery could cut multiple other perforator flaps simultaneously, and the scar is small and hidden. Dissociated the second toe combined metatarsal phalangeal flap could repair shape and function of finger to the maximum extent and donor site is hidden.
