Objective: To analyze the epidemiological characteristics and changing trends of non suicidal self injury (NSSI) behaviors among middle school students in Jiading District of Shanghai, from 2015 to 2023, so as to provide a basis for the development of NSSI prevention and control measures among students. Methods: Using a stratified cluster random sampling method, a total of five times for Shanghai Adolescent Health Risk Behavior Surveys were conducted for every two years in Jiading District of Shanghai from 2015 to 2023. A total of 5 231 middle school students from junior high schools and senior high schools were selected for questionnaire surveys. Intergroup comparisons were performed using the x 2 test or the χ 2 trend test, and the JointPoint 5.0 software was used to analyze the changing trends, with the annual percent change (APC) used for evaluation. A binary Logistic regression model was employed to analyze the related factors of NSSI behavior among middle school students. Results: In 2023, the reported NSSI rate among middle school students in Jiading District was 14.2%. The rate was significantly higher among junior high school students (17.1%) than that among senior high school students (11.1%), and higher among females (19.2%) than that among males (10.0%) ( χ 2=10.04, 23.21, both P <0.01). From 2015 to 2023, the overall reported NSSI rate showed an increasing trend, rising from 8.6% in 2015 to 14.2% in 2023 ( χ 2 trend =22.25), with an APC of 6.64% ( t =3.49), and the APC for girls was 9.79 % ( t =3.20) (all P <0.05). Among students reporting NSSI, the proportion experiencing ≥6 episodes increased from 10.8% in 2015 to 19.2% in 2023 ( χ 2 trend =6.57, P <0.05). Multivariate Logistic regression analysis indicated that girls, junior high school students, those with insomnia, depressive emotion and drinkers had higher risks of NSSI, compared to boys, senior high school students, those without insomnia, non depressive emotion students and non drinkers ( OR =1.71, 1.96, 3.44, 4.76, 1.77, all P < 0.05 ). Conclusions The reported rate of NSSI among middle school students in Jiading District of Shanghai, increased annually from 2015 to 2023, and the proportion of repeated NSSI also showed an upward trend. Early intervention measures targeting middle school students, especially junior high school students and females, should be implemented to prevent and control its occurrence and development.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective:To study the prevalence and distribution of adult thyroid diseases in urban and rural areas of Hebei Province.Methods:A multi-stage stratified cluster sampling method was used to select Renqiu City and Licun Town, Luquan City of Hebei Province as the urban and rural survey sites, respectively. Questionnaire survey, physical examination and thyroid B ultrasound examination were conducted on local permanent residents (≥ 5 years of residencies) over 18 years old. The fasting venous blood sample was collected to determine the serum thyroid function indicaters.Results:A total of 2 650 adults were surveyed, including 1 393 urban residents and 1 257 rural residents (1 357 males and 1 293 females). A total of 435 patients with thyroid diseases were diagnosed, the detection rate was 16.42%. There were seven thyroid diseases, including subclinical hypothyroidism (60.92%, 265/435), Hashimoto's thyroiditis (34.02%, 148/435), hypothyroidism (4.83%, 21/435), simple goiter (3.22%, 14/435), hyperthyroidism (2.53%, 11/435), subclinical hyperthyroidism (2.53%, 11/435), and thyroid cancer (1.84%, 8/435). The detection rates of thyroid diseases in urban and rural areas were 21.18% (295/1 393) and 11.14% (140/1 257), respectively. The detection rates of thyroid diseases in males and females were 11.42% (155/1 357) and 21.66% (280/1 293), respectively. The detection rates of thyroid diseases in 18-< 30, 30-< 40, 40-< 50, 50-< 60 and ≥60 years old were 13.46% (91/676), 14.81% (81/547), 15.42% (89/577), 20.94% (85/406) and 20.05% (89/444), respectively. There were statistically significant differences between different areas, gender and age groups (χ 2 = 48.54, 50.53, 14.68, P < 0.05). Conclusions:The detection rate of subclinical hypothyroidism in adults in urban and rural areas of Hebei Province is relatively high, followed by Hashimoto's thyroiditis. Attention should be paid to the screening, evaluation, and intervention of thyroid function among urban female populations.

Objective:To explore the mechanism of Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma medicinal pair in delaying heart aging based on animal experiments, network pharmacology and molecular docking. Methods:Mice were divided into control group, aging group, metformin group and TCM group according to random number table method. All the groups were injected subcutaneously by D-galactose except the control group to build the subacute aging model. Two weeks later, the metformin group was given metformin suspension (150 mg/kg), the TCM group was given Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma lyophilized powder solution (650 mg/kg), and the control group and aging group were given an equivalent volume of ultrapure water by gastric gavage, once a day, six times a week, for 10 weeks. The level of heart TERT mRNA was detected by PCR; the expression of heart p53 was observed by immunohistochemical staining; the morphology of heart tissue was observed by HE staining. TCMSP and SwissTargetPrediciton databases were used to retrieve the active components and targets of Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma medicinal pair; TTD, OMIM, Gene, HAGR, DisGeNET and other data platforms were used to screen the targets of heart aging; after the drug and disease targets were intersected, the active components of them were collected; STRING database, Cytoscape 3.8.0 software, etc. were used to make PPI of the intersection targets, and screen out the key targets; FunRich was used to perform enrichment analysis of cellular components, molecular functions, biological processes, and biological signal pathways for key targets; Schr?dinger Maestro software was used to do the molecular docking of the screened active components and key targets, and docking results were visualized via PyMOL 2.1 software. Results:Experiment results showed that Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma could significantly ameliorate the damage of aging heart tissues, elevate TERT mRNA level, while significantly reducing the positive expression of p53. A total of 32 active components from the medicinal pair were screened, corresponding to 637 target genes. There were 263 targets for heart aging, and 67 intersection targets of drug active component targets and heart aging targets. 31 key targets were obtained after screening. Enrichment analysis showed that molecular functions were related to transcription factor activity and protein-tyrosine kinase activity. Biological processes involved signal transduction and cell communication. Signaling pathways mainly involved PDGFR-beta, PI3K-Akt, S1P1, Glypican, TRAIL, and Glypican 1. The molecular docking results showed that kaempferol, suchilactone, and ginsenoside Rg5_qt in the medicinal pair had a strong binding ability to p53. Conclusion:Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma may achieve the effect of delaying heart aging by inhibiting p53 expression, providing a foundation for further research on mechanism of invigorating qi and activating blood circulation drugs to delay heart aging.

Objective:To summarize the experience on accurate prevention and control of children′s emergency department during the epidemic of novel coronavirus Omicron variant.Methods:We retrospectively analyzed the strategies and management experience of emergency prevention and control of novel coronavirus infection in emergency department at Children′s Hospital of Fudan University from March to May 2022.Results:As a designated hospital for treating pediatric patients who contracted novel coronavirus in Shanghai, the emergency department in our hospital was confronted with the dual pressure of critical patients treatment and pandemic prevention and control.We carefully studied a series of laws and regulations, as well as the newest edition of Chinese clinical guidance for novel coronavirus pneumonia diagnosis and treatment, and combined with the characteristics of novel coronavirus infection in children, then formulated the independent emergency department, fever clinics and novel coronavirus clinics; Updated the emergency department pre-examination triage process, the precautions pratice of clinical stuffs and disfection strategy, and established the second emergency department.From the beginning of March to the end of May 2022, a total of about 12 000 patients were admitted to the emergency department in our hospital, including 704 patients in the resuscitation room, 652 patients in the observation room, and 164 patients in the emergency ward.There were six patients with novel coronavirus infection in the emergency department.Neither nosocomial infection nor occupational exposure occurred.Conclusion:After 3 months of practice, the results showed that it can fully guarantee the timely treatment of critically ill children and achieved zero cross-infection in the hospital, which has important reference significance for the treatment of children, epidemic prevention, control during the novel coronavirus epidemic.

Objective:To investigate the characteristics of transcranial sonography (TCS) in patients with restless legs syndrome (RLS), and analyze the correlations of scores of RLS Self-rating Severity Scale by International Restless Leg Syndrome Study Group (IRLS) and TCS parameters with clinical data of these patients.Methods:Twenty-one patients with RLS admitted to the Sleep Disorder Clinic of our hospital from September 2020 to January 2021 were selected as RLS group, and 23 healthy controls at the same time period were recruited as control group. IRLS was used to evaluate the severity of patients in the RLS group, and the 14-item Hamilton anxiety rating scale (HAMA-14) and 24-item Hamilton depression rating scale (HAMD-24) were used to evaluate the anxiety and depression of subjects from the 2 groups. Pittsburgh Sleep Quality Scale (PSQI), Insomnia Severity Index (ISI) and Epworth Sleepiness Scale (ESS) were used to evaluate the sleep quality of subjects from the 2 groups. TCS was used to examine the occurrence of hypoechoic substantia nigra and raphe nucleus rupture and the width of the third ventricle in the two groups. The clinical data and TCS parameters of patients in the 2 groups were compared, and the correlations of IRLS scores and TCS parameters with clinical features of patients in the RLS group were analyzed.Results:As compared with those in the control group, the HAMA-14, HAMD-24, ISI and PSQI scores in the RLS group were statistically higher ( P<0.05). As compared with the control group, RLS group had significantly higher proportion of patients with hypoechoic substantia nigra or raphe nucleus rupture ( P<0.05). In RLS patients, the IRLS scores were positively correlated with HAMA-14, HAMD-24, and ISI scores ( P<0.05); ESS scores were negatively correlated with hypoechoic substantia nigra and width of the third ventricle ( rs=-2.005, P=0.045; r=-0.477, P=0.029); width of the third ventricle was negatively correlated with gender (male) and years of education ( rs=-0.592, P=0.005; r=-0.627, P=0.002), and positively correlated with age and course of the disease ( r=0.756, P<0.001; r=0.167, P=0.047). Conclusions:Patients with RLS are prone to anxiety, depression and sleep disorders; their TCS shows hypoechoic substantia nigra and raphe nucleus rupture. RLS severity may affect HAMA-14, HAMD-24, and ISI scores. Gender, age, years of education, course of disease, and ESS scores of RLS patients may affect TCS related parameters.

Objective:To investigate the clinical features, diagnosis, treatment and prognosis of children with osteomyelitis caused by Streptococcus pneumonia. Methods:The demographic characteristics, diagnosis, clinical manifestations, imaging features, treatment and short-term prognosis of Streptococcus pneumonia osteomyelitis cases in 18 children′s hospitals from January 2012 to December 2017 were retrospectively collected and analyzed. Results:A total of 9 cases were enrolled, with a median age of 1 year and 3 months.Four children had underlying diseases.The main manifestations were local swelling, pain, limited mobility (9 cases) and fever (8 cases). Sites of infection included humerus (4 cases), femur (3 cases) and tibiofibula (2 cases), and 8 cases were complicated with septic arthritis; The laboratory tests showed increased white blood cells (8 cases, median 22.02×10 9/L), C-reactive protein (7 cases, median 55.44 mg/L) and erythrocyte sedimentation rate (6 cases, median 70 mm/1 h) of those patients.Five patients received monotherapy in the initial treatment regimen with cephalosporins. Then the therapeutic schedules were adjusted according to the culture and antibiotic sensitivity. All patients were treated with puncture, incision drainage or fenestrating decompression.Eight patients were cured and discharged finally. Conclusions:Streptococcus pneumonia osteomyelitis is more common in younger children and may have no risk factors.The common infection site is long bone metaphysis, and those patients are easily complicated with septic arthritis.Antibiotic combined with surgical treatment are crucial to a good outcome.

Objective:To analyze features of sarcopenia and its influencing factors in hospitalized patients at our department.Methods:This was a cross-sectional study.A total of 180 patients aged 80.3±6.7 years admitted to the geriatrics department of our hospital were consecutively recruited.Patients were divided into the non-sarcopenia group(n=80, 44.4%)and the sarcopenia group(n=100, 55.6%)based on the diagnostic criteria for sarcopenia of the Asian Sarcopenia Working Group.All subjects were evaluated by using the comprehensive geriatric assessment.Differences in comorbidity, physical function, nutrition, cognitive function, psychological characteristics, geriatric syndromes, medication and other aspects were analyzed between the two groups.The correlation of the above factors with sarcopenia was analyzed.Results:Scores on the Charlson comorbidity index and the cumulative illness rating scale were higher in the sarcopenia group than in the non-sarcopenia group(2.6±1.7 vs.2.1±1.1, 11.3±4.1 vs.7.9±1.8, P<0.05). Scores on mini-nutrition assessment and mini-cog, grip, chair-rising test(five times), timed get-up and go test(3 m), walking speed, and short physical performance battery were lower in the sarcopenia group than in the non-sarcopenia group[(12.8±2.1) vs.(11.2±1.7), (2.3±1.0) vs.(4.4±0.9), (21.2±5.8)kg vs.(27.6±6.2)kg, (31.4±15.3)s vs.(13.2±4.0)s, (24.2±9.5)s vs.(12.0±2.9)s, (0.6±0.2)m/s vs.(0.9±0.3)m/s, (6.1±1.9) vs.(9.8±1.3), respectively, P<0.05]. The incidences of geriatric syndromes such as incontinence, visual impairment, hearing impairment, sleeping disorders, oral problems, chronic pain, anxiety, depression and falls were higher in sarcopenia patients than in non-sarcopenia patients.Logistic regression analysis showed that body mass index, walking speed and the number of geriatric syndromes were risk factors for sarcopenia( OR=1.401, 1.286 and 3.654, P<0.05). Conclusions:The incidence of sarcopenia is high in hospitalized elderly patients.Comprehensive geriatric assessment can be used to achieve a more complete understanding of the characteristics and influencing factors for patients with sarcopenia and will help provide a basis for appropriate treatment plans.
