Objective:To investigate the efficacy of repetitive transcranial magnetic stimulation (rTMS) in the treatment of negative symptoms in patients with schizophrenia and its effect on brain-derived neurotrophic factor (BDNF).Methods:A total of 130 patients with negative symptoms of schizophrenia who received treatment at The Third Hospital of Quzhou from March 2021 to March 2023 were included in this randomized controlled study. They were divided into a control group and a study group ( n = 65 per group). Both groups of patients were treated with antipsychotic drugs. Based on this, patients in the study group were treated with high-frequency rTMS, while those in the control group were treated with pseudo-rTMS. After 8 weeks of treatment, Positive and Negative Syndrome Scale (PANSS), Scale for Assessment of Negative Symptoms (SANS), and Personal and Social Performance Scale (PSP) scores were evaluated in each group before and after treatment. Serum BDNF levels were compared between the two groups before and after treatment. Adverse reactions were observed during the treatment. Results:After 8 weeks of treatment, the PANSS negative subscale score and SANS score in the study group were (16.45 ± 3.98) points and (35.41 ± 6.29) points, respectively, which were significantly lower than (20.08 ± 4.16) points and (41.76 ± 7.36) points in the control group ( t = -7.46, -6.85, both P < 0.05). PSP score in the study group was (66.85 ± 8.93) points, which was significantly higher than (58.79 ± 8.28) points in the control group ( t = 5.62, P < 0.001). There were no significant differences in PANSS positive subscale score, general psychopathology scale score or total score between the two groups (all P > 0.05). After 8 weeks of treatment, the serum BDNF level in the study group was (12.05 ± 2.13) μg/L, which was significantly higher than (8.86 ± 1.94) μg/L in the control group ( t = 9.73, P < 0.001). There was no significant difference in the incidence of adverse reactions during the treatment period between the two groups ( P > 0.05). Serum BDNF level was negatively correlated with PANSS and SANS scores ( r = -0.81, -0.85, both P < 0.001), while it was positively correlated with PSP score ( r = 0.82, P < 0.001). Conclusion:High-frequency rTMS can effectively alleviate the negative symptoms of schizophrenia, increase the secretion of BDNF, and be highly safe.

Objective:To determine the application effect of the "full chain" information-based health management model in the home care of children with bronchial asthma.Methods:Sixty children with bronchial asthma who were hospitalized in the Respiratory Department of Xuzhou Children's Hospital from January to June 2020 were selected and divided into a control group and an observation group according to a random number table with 30 cases in each group. The control group received routine nursing care, and the observation group implemented a "full-chain" informatized health management on the basis of the control group.The intervention time was 6 months. The condition control, medication compliance, self-management and airway function were observed and compared between the two groups.Results:After 6 months of intervention, the frequency of attacks, emergency cases, the medication compliance, the maximum expiratory flow rate, symptom days and peak expiratory flow days were 6.67%(2/30), 3.33%(1/30), 93.33%(28/30), (1.83±0.23) L, (163.00±6.74) d, (168.00±3.78) d in the observation group, and 26.67%(8/30), 20.00%(6/30), 66.67%(20/30), (1.67±0.24) L, (144.00±5.88) d, (157.00±4.08) d in the control group. The differences were statistically significant (χ 2 values were 4.320, 4.043, 6.667, t values were 2.636, 11.635, 10.833, P<0.05). There was no significant difference in the ratio of forced expiratory volume and forced expiratory volume in forced vital capacity in the first second after 6 months of intervention between the two groups ( P>0.05). Conclusions:"Full chain" information health management can reduce the number of attacks and emergency visits of children with asthma, effectively improve medication compliance, thus improving airway function and improving the quality of life of children.

Objective:To determine the level of epilepsy knowledge of caregivers for children with epilepsy and analyze its influencing factors, and investigate caregivers' educational needs and their acceptance for remote education, in order to provide reference for clinical telenursing education.Methods:From March to September 2022, 221 caregivers of epileptic children in the outpatient department and ward of neurology department of Xuzhou Children's Hospital were recruited by convenient sampling method for cross-sectional investigation. The status of caregivers' knowledge and educational needs were investigated by the general information questionnaire, epilepsy knowledge questionnaire, epilepsy knowledge needs questionnaire and telenursing acceptance questionnaire, and the influencing factors of knowledge level were analyzed by multiple linear regression.Results:The average score of epilepsy knowledge of caregivers was (15.68 ± 6.43) points. The course of disease, taking medicine on time, education background and monthly income of caregivers were the influencing factors of caregivers' knowledge level, and the difference was statistically significant ( P <0.05). 94.12% (208/221)- 96.38% (213/221) of the caregivers had high educational needs, and they had the highest demand for safety guidance during seizures. Caregivers' acceptance of remote education was moderate, ranging from 34.39% (76/221) to 71.95% (159/221). Conclusions:Caregivers' epilepsy knowledge needs to be improved. Medical institutions should formulate education plans according to the different characteristics of caregivers. Caregivers have a high demand for nursing knowledge, and medical staff should increase health education. Before giving health education based on remote nursing platform, we should fully understand the attitude of caregivers to the platform, so that they can master disease knowledge, strengthen their disease management ability, and improve the quality of life of children.

Objective:To explore the impact of hypophosphatemia on the occurrence and prognosis of critically ill patient.Methods:The clinical data of critically ill patients admitted to the intensive care unit (ICU) of Tianjin First Central Hospital from October 2021 to April 2022 were retrospectively analyzed. Patients were divided into hypophosphatemia group (serum phosphorus level < 0.80 mmol/L) and non-hypophosphatemia group (serum phosphorus level ≥ 0.80 mmol/L) when they were admitted to the ICU. The following variables were also collected, including gender, age, acute physiology and chronic health evaluationⅡ(APACHE Ⅱ), sequential organ failure assessment (SOFA), serum phosphorus level, serum calcium level, serum magnesium level, white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP), presence of infection and infection site, length of hospital stay, ICU stay, 28-day mortality, and mechanical ventilation time. Multivariate Logistic regression analysis was used to evaluate the relationship between each variable and the 28-day mortality. The receiver operator characteristic curve (ROC curve) was drawn, and the area under the ROC curve (AUC) and 95% confidence interval (95% CI) were calculated to evaluate the predictive value of serum phosphorus levels for the prognosis of ICU patients. Results:A total of 263 patients were enrolled, including 54 patients with hypophosphatemia and 209 patients without. The SOFA score, LYM level and the infection rate of patients in the hypophosphatemia group were significantly higher than those in the non-hypophosphatemia group [SOFA score: 6.70±3.17 vs. 5.64±3.59, LYM (×10 9/L): 0.99±0.54 vs. 0.77±0.54, infection rate: 77.78% (42/54) vs. 59.33% (124/209), all P < 0.05], the NLR was significantly lower than that of the non-hypophosphatemia group [10.67 (7.08, 18.02) vs. 12.25 (7.25, 21.68), P < 0.05]. The length of hospital stay, ICU stay, and mechanical ventilation duration in the hypophosphatemia group were significantly longer than those in the non-hypophosphatemia group [length of hospital stay (days): 15 (11, 28) vs. 12 (6, 21), length of ICU stay (days): 10.35±7.80 vs 7.15±6.61, mechanical ventilation duration (days): 3 (0, 12) vs. 2 (0, 5), all P < 0.05]. There was no significant difference in the 28-day mortality between the hypophosphatemia group and the non-hypophosphatemia group [9.26% (5/54) vs. 11.00% (23/209), P > 0.05]. Multivariate Logistic regression analysis showed that APACHE Ⅱ score [odds ratio ( OR) = 1.188, 95% CI was 1.110-1.271], CRP ( OR = 1.016, 95% CI was 1.007-1.026), and NLR ( OR = 1.002, 95% CI was 0.996-1.008) were independent risk factors affecting the 28-day mortality of critically ill patients in ICU (all P < 0.05). ROC curve analysis showed that the AUC of serum phosphorus levels for predicting the length of hospital stay of critically ill patients in ICU > 10 days, ICU stay > 5 days, and mechanical ventilation duration > 5 days were 0.701 (95% CI was 0.632-0.770), 0.771 (95% CI was 0.691-0.852), 0.617 (95% CI was 0.541-0.692), respectively, all P < 0.01. Conclusion:Hypophosphatemia has some predictive value for the length of hospital and ICU stay and mechanical ventilation time in critically ill patients, but it cannot predict the 28-day mortality.

Chinese Journal of School Health 2023;44(3):398-402
Objective:
To explore cyberbullying and risk factors of middle school students, and to provide a reference for cyberbullying prevention in school settings.
Methods:
A stratified cluster random sampling method was used to select 12 940 students from three junior high schools and four senior high schools in Yixing City of Jiangsu Province, China, to conduct a questionnaire survey from March 1 to May 31, 2019. The Chi -square test was performed to compare differences in the prevalence of cyberbullying among groups with different sociodemographic characteristics, and the multivariate Logistic regression model was employed to analyze the risk factors. A risk predictive nomogram model was constructed and then verified.
Results:
Middle school students were found to be victims of cyberbullying at a rate of 12.3%. The Logistic regression results showed that alcohol use ( OR =1.93), lack of emotional management ( OR =1.30), feeling unsafe ( OR =1.70), not trusting people ( OR =1.66), increased daily online time ( OR =1.39), higher frequency of using social software or websites ( OR =2.24), poor relationships with family members ( OR =1.46), parental neglect ( OR =1.50), class leadership ( OR =1.30) and poor relationships with classmates ( OR =1.34) were risk factors for middle school students who were victims of cyberbullying ( P <0.05). Based on these 10 independent risk factors, the nomogram prediction model, had good discrimination ( AUC =0.73).
Conclusion
Cyberbullying is common among middle school students. Internet use, parental neglect and class leadership all have an impact on cyberbullying.
9.Latent classes and associated factors of suicidal ideation among high school students
Chinese Journal of School Health 2024;45(1):66-71
Objective:
To understand current situation epidemiology and associated factors of suicidal ideation among high school students in Yixing, so as to provide basis for targeted intervention.
Methods:
From March to May 2019, a questionnaire survey was conducted on 12 799 students from 3 junior high schools and 4 senior high schools in Yixing City, Jiangsu Province, using a stratified cluster random sampling method. Latent profile analysis was used to classify suicidal ideation among high school students, the chi square test was used to compare the differences in suicidal ideation among different characteristics of students, multiple Logistic regression was used to analyze influencing factors, a risk predictive nomogram model was constructed and then verified.
Results:
Three latent classes of suicidal ideation among high school students was divided into three categories were observed: none or mild, moderate, and severe. Among them, 3 034 (23.7%) had moderate suicidal ideation and 753 (5.9%) had severe suicidal ideation. The Logistic regression results showed that gender was female, academic performance was lower midrange, smoking, drinking, popularity with classmates(less popular and unpopularity), family member relationships(general/occasional contradictions/contradictions), trust in others(more trusted/less trusted/less trusted at all), past or current relationships, physical bullying, relationship bullying, verbal bullying, and sexual bullying were the influencing factors for severe suicidal ideation among students ( OR =3.27; 2.18 ;1.63;1.72;2.66, 6.05;3.00,3.29, 6.38;1.71, 6.04, 12.48; 2.50; 1.59; 2.16; 1.45; 1.63, P <0.05). The nomogram prediction model had good discrimination.
Conclusions
Suicide ideation is influenced by multiple factors. Family and peer situations, as well as being bullied, are all related to the degree the severity of suicidal ideation. Efforts can be made to improve students family and interpersonal relationships, control bullying, then reduce their suicidal ideation which might help prevent suicide ideation among students.
10.Association of anxiety, insomnia, and family cohesion with Internet addiction and non suicidal self injury behavior in junior and senior school students
Chinese Journal of School Health 2023;44(12):1770-1774
Objective:
To explore the mediating effect of anxiety, insomnia, and family cohesion between Internet addiction and non suicidal self injury (NSSI) behavior among junior and senior school students, so as to develop interventions to promote adolescent mental health.
Methods:
A total of 3 026 junior and senior school students from Yixing, Jiangsu Province, China, were selected by stratified cluster sampling from December 2022 to February 2023, and were administered the Ottawa Self injury Inventory (OSI), Depression, Anxiety and Stress Scale-21 (DASS-21), Family Environment Scale-Chinese Version (FES-CV), Insomnia Severity Index (ISI), and Chinese Internet Addiction Scale Revised (CIAS-R). A mediating effect model was constructed to analyze the mediating effect of anxiety, insomnia, and family cohesion on Internet addiction and NSSI.
Results:
Internet addiction ( r = 0.24), insomnia ( r =0.28), and anxiety ( r =0.27) were positively correlated with NSSI, while the latter was negatively correlated with family cohesion ( r =-0.23) ( P <0.01). The mediating effect model was well fitted ( CFI=0.999, TLI=0.978, RMSEA = 0.030 ). Anxiety (mediation effect value:0.12, 95% CI =0.08-0.18) and family cohesion (mediation effect value:0.08, 95% CI = 0.03 -0.13) had a separate mediating effect. A chain meditating effect was found in the case of anxiety and insomnia (mediation effect value:0.14, 95% CI =0.10-0.20), family cohesion and anxiety (mediation effect value:0.05, 95% CI =0.03-0.07), family cohesion and insomnia (mediation effect value:0.05, 95% CI =0.03-0.07), and family cohesion, anxiety, and insomnia (mediation effect value:0.06, 95% CI =0.04-0.08). The mediating effect accounted for 14.9%, 10.1%, 17.5%, 6.0%, 5.6%, and 7.1%, respectively.
Conclusions
Anxiety, insomnia, and family cohesion partially mediate Internet addiction and NSSI. Schools and families should pay attention to Internet addiction among junior and senior school students and develop appropriate interventions to promote adolescent mental health, so as to reduce the prevalence of NSSI.
