Objective:To study the life characteristics and related risk factors of patients with depression in Shandong Province.Methods:Based on the 2015 mental epidemiological survey database in Shandong Province,a total of 832 patients with depression,807 high-risk individuals with depression,and 819 low-risk individuals were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)and the Structured Clinical Interview for DSM-Ⅳ-TR Axis I Disorders,Research Version(SCID-I/P).In 2020,SCID-I/P was used for re diagnosis,and the General Health Questionnaire(GHQ-12),Simple Quality of Life question-naire,Pittsburgh sleep quality index(PSQI),Childhood Trauma Questionnaire(CTQ),Social Support Rating Scale(SSRS),Global Pain Scale(GPS),Montreal Cognitive Assessment(MoCA),Simplified Coping Style Question-naire(SCSQ)were used for evaluation.Compare changes in the quality of life of depression patients and construct a risk factor model.Results:Patients with depression had lower scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those in the high-and low-risk groups,those in remission of depression had higher scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those in non-re-mission,and those with new-onset disorder in the high-and low-risk groups had lower scores on the simple quality of life questionnaire at baseline and at retest after 5 years than those with no-onset disorder(Ps＜0.001).Depres-sion diagnosis and PSQI scale scores at baseline negatively predicted at retest after 5 years(β=-0.06,-0.15),while coping style tendencies at baseline positively predicted(β=0.06).The simple quality of life questionnaire at baseline negatively predicted depression diagnosis at retest after 5 years,GHQ-12 scores at retest after 5 years,and PSQI scale scores at retest after 5 years(β=-0.11,-0.17,-0.09),while the simple quality of life question-naire at baseline positively predicted coping style tendencies at retest after 5 years(β=0.13).Depression diagnosis at retest after 5 years,GHQ-12 scores at retest after 5 years,PSQI scale scores at retest after 5 years,coping style tendencies at retest after 5 years,SSRS scale scores,CTQ scale scores,GPS scale scores,and the simple quality of life questionnaire at baseline all influenced the simple quality of life questionnaire at retest after 5 years through ei-ther direct or indirect pathways.Conclusion:It suggest that the quality of life is lower in patients with depression than in the general population.Depression diagnosis,sleep,mental health,pain,social support,childhood trauma and coping are direct and indirect risk factors affecting life.

Objective:To understand the current status of pubertal sexual characteristics development of girls aged 6-18 years in Tongzhou District of Beijing and to compare the differences in sexual characteristics development among girls characterized as thin, normal, overweight, and obese.Methods:A cross-sectional survey was conducted among 2 844 girls aged 6-18 years in Tongzhou District of Beijing from September 2022 to July 2023. The developmental stages of breast and pubic hair were assessed on site, and menarche status was inquired. Weight and height were measured. The girls were subsequently characterized into thin, normal, overweight and obese groups. Basic information (including family and personal history) was obtained through questionnaires. Probit probability unit regression was applied to calculate the age of each Tanner stage of sexual characteristics development and the age of menarche. The χ 2 test was applied to compare the counting data between two or multiple groups. Results:A total of 2 844 girls were surveyed and 2 704 girls met the inclusion criteria, resulting in a valid response rate of 95.1%. Among these girls, 1 105 (40.9%) were aged 6-9 years, 1 053 (38.9%) were aged 10-13 years, and 546 (20.2%) were aged 14-18 years. The of height-for-age Z-score (HAZ), weight-for-age Z-score (WAZ), and body mass index-for-age Z-score (BAZ) were 0.46(-0.23,1.16), 0.69(-0.16,1.67), and 0.67(-0.27,1.73) respectively. The prevalences of thin, overweight, and obesity were respectively 1.7% (45/2 704), 17.3% (467/2 704), and 19.9% (538/2 704), respectively. There were 45 girls in the thin group, 1 654 girls in the normal weight group, 1 005 girls in the overweight and obesity group. The age of Tanner stage breast 2 (B2), Tanner stage pubic hair 2 (P2), and menarche was 9.0 (95% CI 8.9-9.1), 10.5 (95% CI 10.4-10.6), and 11.4 (95% CI 11.3-1.5) years, respectively. The current status of breast and pubic hair maturity in girls with pubertal development shows that 64.6% (1 211/1 874) of these girls had breast development preceding pubic hair development, 32.4% (607/1 874) had concurrent breast and pubic hair development, and 3.0% (56/1 874) had pubic hairs development preceding breast development. The interval age between B2 and B5 was 4.7 (95% CI 4.6-4.8) years, between P2 and P5 was 4.5 (95% CI 4.4-4.6) years, and between B2 and menarche was 2.4 (95% CI 2.3-2.5) years. The ages of sexual characteristics development in overweight and obese groups were earlier than that in normal and thin groups. The ages of B2 in thin, normal, overweight, and obese groups were 10.0 (95% CI 9.5-10.6), 9.3 (95% CI 9.2-9.4), and 8.6 (95% CI 8.4-8.7) years, respectively. The age of menarche in thin, normal, overweight, and obese groups were 13.1 (95% CI 12.4-13.7), 11.6 (95% CI 11.4-11.7), and 11.1 (95% CI 11.0-11.2) years, respectively. The interval ages between B2 and B5 and between P2 and P5 was 4.5 and 4.1 years, respectively in the overweight and obese groups, and those in normal group and thin group was 4.7 and 4.5 years, 4.6 and 4.7 years, respectively. Conclusions:The ages of sexual characteristics development and menarche tend in Tongzhou District of Beijing to be earlier than that being reported of Beijing's survey 20 years ago. Girls characterized as overweight and obese not only start puberty at an earlier age than girls of normal weight, but also have a shorter developmental process.

Objective:To analyze the confirmation rate of human immunodeficiency virus (HIV), the clinical epidemiological characteristics of confirmed HIV-infected individuals, and the performance of HIV screening reagents, so that to provide scientific basis for local development of acquired immunodeficiency syndrome prevention and control measures.Methods:Clinical data of HIV infected individuals who were suspected to be positive during the initial screening of HIV in Xinhua Hospital, Shanghai Jiao Tong University School of Medicine and confirmed by the HIV confirmed laboratory of Center for Disease Control and Prevention in Yangpu District Center, Shanghai City from January 2012 to December 2022 were retrospectively analyzed, and the analysis of the clinical epidemiological characteristics of HIV confirmed positive infections was performed. The consistency was analyzed between the screening results and confirmation results of HIV initial screening reagents. Trend chi-square test was used for statistical analysis. Receiver operating characteristic (ROC) curve was used to analyze the diagnostic ability of HIV initial screening chemiluminescence values.Results:A total of 702 949 outpatient/inpatient patients and healthy individuals were screened, with 468 suspected positive cases (0.067%) initially screened and 202 confirmed HIV positive cases, with a positive rate of 0.028 7%. The HIV confirmed positive rate showed a downward trend from 2012 to 2022 ( χtrend2=17.28, P<0.001). Among confirmed HIV positive patients, there were 180 males (89.11%) and 22 females (10.89%). Among the confirmed HIV positive cases, Shanghai City residents accounted for 56.44%(114 cases), while Anhui Province residents accounted for 8.91% (18 cases) and Jiangsu Province residents accounted for 7.92% (16 cases). There were 70 cases (34.65%) of HIV co-infection with Treponema pallidum. The area under the ROC curve of the chemiluminescence value of the HIV initial screening test (chemiluminescence particle immunoassay) was 0.973 (95% confidence interval ( CI) 0.961 to 0.985, P<0.001). The optimal critical value corresponding to the Youden index was 0.834, and the corresponding chemiluminescence value was 59.48 signal/cut off (S/CO), with the sensitivity of 89.10% and the specificity of 94.30%. The accuracy of HIV antibody colloidal gold method was 85.95% (318/370), with the sensitivity of 98.30% (173/176) and the specificity of 97.32% (145/149). Conclusions:The positive rate of HIV testing shows a downward trend. HIV infected people are mainly male, and registered residence is mainly distributed in Shanghai City. The HIV antibody colloidal gold method has high specificity.

Purpose: The risk stratification of pediatric anaplastic large cell lymphoma (ALCL) has not been standardized. In this study, new risk factors were included to establish a new risk stratification system for ALCL, and its feasibility in clinical practice was explored. Materials and Methods: On the basis of the non-Hodgkin’s lymphoma Berlin–Frankfurt–Munster 95 (NHL-BFM-95) protocol, patients with minimal disseminated disease (MDD), high-risk tumor site (multiple bone, skin, liver, and lung involvement), and small cell/lymphohistiocytic (SC/LH) pathological subtype were enrolled in risk stratification. Patients were treated with a modified NHL-BFM-95 protocol combined with an anaplastic lymphoma kinase inhibitor or vinblastine (VBL). Results: A total of 136 patients were enrolled in this study. The median age was 8.8 years. The 3-year event-free survival (EFS) and overall survival of the entire cohort were 77.7% (95% confidence interval [CI], 69.0% to 83.9%) and 92.3% (95% CI, 86.1% to 95.8%), respectively. The 3-year EFS rates of low-risk group (R1), intermediate-risk group (R2), and high-risk group (R3) patients were 100%, 89.5% (95% CI, 76.5% to 95.5%), and 67.9% (95% CI, 55.4% to 77.6%), respectively. The prognosis of patients with MDD (+), stage IV cancer, SC/LH lymphoma, and high-risk sites was poor, and the 3-year EFS rates were 45.3% (95% CI, 68.6% to 19.0%), 65.7% (95% CI, 47.6% to 78.9%), 55.7% (95% CI, 26.2% to 77.5%), and 70.7% (95% CI, 48.6% to 84.6%), respectively. At the end of follow-up, one of the five patients who received maintenance therapy with VBL relapsed, and seven patients receiving anaplastic lymphoma kinase inhibitor maintenance therapy did not experience relapse. Conclusion This study has confirmed the poor prognostic of MDD (+), high-risk site and SC/LH, but patients with SC/LH lymphoma and MDD (+) at diagnosis still need to receive better treatment (ClinicalTrials.gov number, NCT03971305).

Pulmonary hypertension (PH) is an extremely malignant pulmonary vascular disease of unknown etiology. ADAR1 is an RNA editing enzyme that converts adenosine in RNA to inosine, thereby affecting RNA expression. However, the role of ADAR1 in PH development remains unclear. In the present study, we investigated the biological role and molecular mechanism of ADAR1 in PH pulmonary vascular remodeling. Overexpression of ADAR1 aggravated PH progression and promoted the proliferation of pulmonary artery smooth muscle cells (PASMCs). Conversely, inhibition of ADAR1 produced opposite effects. High-throughput whole transcriptome sequencing showed that ADAR1 was an important regulator of circRNAs in PH. CircCDK17 level was significantly lowered in the serum of PH patients. The effects of ADAR1 on cell cycle progression and proliferation were mediated by circCDK17. ADAR1 affects the stability of circCDK17 by mediating A-to-I modification at the A5 and A293 sites of circCDK17 to prevent it from m1A modification. We demonstrate for the first time that ADAR1 contributes to the PH development, at least partially, through m1A modification of circCDK17 and the subsequent PASMCs proliferation. Our study provides a novel therapeutic strategy for treatment of PH and the evidence for circCDK17 as a potential novel marker for the diagnosis of this disease.

Objective: To evaluate the impact of bleomycin/etoposide/cisplatin (BEP) and paclitaxel/carboplatin (PC) chemotherapy regimens on the fertility and prognostic outcomes in malignant ovarian germ cell tumor (MOGCT) patients who underwent fertility-sparing surgery (FSS). Methods: A propensity score matching algorithm was performed between the BEP and PC groups. The χ2 test and the Kaplan-Meier method were used to compare the fertility outcome, disease-free survival (DFS) and overall survival (OS). The Cox proportional hazards regression analysis was used to identify risk factor of DFS. Results: We included 213 patients, 185 (86.9%) underwent BEP chemotherapy, and 28 (13.1%) underwent PC chemotherapy. The median age was 22 years (range, 8–44 years), and the median follow-up period was 63 months (range, 2–191 months). Fifty-one (29.3%) patients had a pregnancy plan, and 35 (85.4%) delivered successfully. In the before and after propensity score matching cohorts, there were no significant differences in spontaneous abortion, selective termination of pregnancy, during-pregnancy status, and live birth between the BEP and PC groups (p>0.05). Fourteen (6.6%) patients experienced recurrence, including 11 (5.9%) in the BEP group and 3 (10.7%) in the PC group. Four (1.9%) patients in the BEP group died. Kaplan-Meier analysis revealed no significant differences in DFS (p=0.328) and OS (p=0.446) between the BEP and PC groups, and the same survival results were observed in the after matching cohort. Conclusion The PC regimen is as safe as the BEP regimen for MOGCT patients with fertility preservation treatment, and no differences were observed in fertility and clinical prognosis.

Objective:To compare the clinical features, laboratory test results and imaging findings between cases of Mycoplasma pneumoniae ( Mp) infection complicated by coagulation dysfunction and isolated Mp infection, and analyze the predictive value of related indicators for Mp infection with coagulation dysfunction. Methods:A total of 65 cases of Mp infection complicated by coagulation dysfunction (case group) and 92 cases of isolated Mp infection (control group) treated in the Children′s Hospital Affiliated to Capital Institute of Pediatrics in 2021 were enrolled. Clinical data of the two groups were compared, and receiver operating characteristic (ROC) curves were drawn to analyze the predictive value of differential indicators to the case group. Results:There were no significant differences in the general clinical features or imaging findings between the case group and the control group. The levels of fibrinogen (FIB), D-Dimer, fibrinogen degradation product (FDP), IgE, lactic dehydrogenase (LDH), alanine transaminase (ALT), aspartate aminotransferase (AST), adenosine deaminase (ADA) and C-reactive protein (CRP), activated partial thromboplastin time (APTT), thrombin time (TT), blood platelet count (PLT), neutrophil count, length of hospital stay, peak body temperature, and duration of cough and fever in the case group were higher than those in the control group, and the differences were statistically significant ( P<0.05). The areas under ROC curves of LDH, CRP, peak body temperature, ADA, ALT, neutrophil count, AST and IgE for predicting Mp infection complicated by coagulation dysfunction were 0.855, 0.810, 0.730, 0.716, 0.692, 0.648, 0.631 and 0.603, respectively. The area under ROC curve of LDH, CRP and peak body temperature used in combination was 0.901. Conclusions:LDH, CRP, peak body temperature, ADA, ALT, neutrophil count, AST and IgE had predictive value for Mp infection complicated by coagulation dysfunction, among which LDH, CRP and peak body temperature had higher predictive value. LDH, CRP and peak body temperature used in combination had the highest diagnostic value (AUC=0.901).

Objective: To compare bioelectrical impedance analysis (BIA) and dual energy X ray absorptiometry (DXA) for measuring body mineral content (BMC) of children and adolescents, and to provide a basis for BIA to accurately measure BMC in children and adolescents. Methods: By using the convenience sampling method, among 1 469 children and adolescents aged 7-17 were recruited in Guangzhou from April to May 2019, the BMC was measured by DXA and BIA. The intraclass correlation coefficient ( ICC ) and Bland Altman analysis were used to evaluate the agreement between BIA and DXA. Bland Altman analysis was performed on log transformed data. The BMC was categorized into age and specific tertiles, and the agreement between methods was evaluated based on the kappa coefficients. Treating the BMC with DXA as the dependent variable, a prediction model was constructed for correcting the BIA measure. Results: The ICC s were 0.93 and 0.94 for boys and girls, respectively. In Bland Altman analysis, the limits of agreements for the BIA to DXA ratio were wide in boys and girls, ranging from 0.27-0.76 and 0.17-0.72, respectively. The kappa coefficients for categorized BMC levels were 0.57 and 0.45 for boys and girls, respectively, showing a fair to good degree of agreement. When sub grouped by BMI, the kappa coefficients for all BMI groups of boys and overweight girls were all >0.75 , with an excellent agreement. The prediction models for boys and girls were as follows: BMC DXA =-0.51+0.44× BMC BIA + 0.06× Age +0.02× BMI ; and BMC DXA =-0.55+0.43× BMC BIA +0.06× Age +0.02× BMI , respectively. The R 2 for models of boys and girls were 0.87 and 0.87, respectively. Conclusion The agreement between BIA and DXA was poor for measuring BMC, but acceptable when evaluating the categorized BMC levels, suggesting the BIA may be applied in assessment of the BMC levels when compared to the age and gender specific population. Additionally, the prediction model for correcting BMC by BIA fis well to the measurement by DXA.
