Objective: To explore the impact of sleep quality, experience of childhood maltreatment, and their interaction on depressive symptoms among middle school students, so as to provide the reference for early intervention of depressive symptoms among middle school students. Methods: From September to December 2023, a questionnaire survey was conducted among 1 231 students from two secondary schools in Harbin, Heilongjiang Province by a convenient sampling method. The survey included general demographic information, Childhood Trauma Questionnaire Short Form, Pittsburgh Sleep Quality Index and Short Version of Center for Epidemiological Studies Depression Scale. The Chi square test was used to analyze the differences in depressive symptom, sleep quality and childhood maltreatment among students with different demographic characteristics. Correlation analysis was conducted using Logistic regression, and interaction analysis was performed by both additive and multiplicative interaction models. Results: The detection rate of depressive symptoms among middle school students was 22.7%, and the rate for high school students (35.2%) was significantly higher than that for middle school students (17.0%) ( χ 2=50.35, P <0.01). The detection rates of depressive symptoms among middle school students with a history of childhood maltreatment and poor sleep quality were 45.8% and 44.0%, respectively. Multivariate Logistic regression analysis showed that compared to students without a history of childhood maltreatment, students with a history of childhood maltreatment had a higher risk of depressive symptoms ( OR =4.49，95% CI =3.31~ 6.09 , P <0.01);students with poor sleep quality had a higher risk of depressive symptoms than students with good sleep quality ( OR = 5.99，95% CI =4.37~8.22, P <0.01).The interaction results showed that the presence of childhood maltreatment and poor sleep quality had an additive interaction on the occurrence of depression in middle school students. Compared with students without childhood maltreatment and having good sleep quality, students with childhood maltreatment and poor sleep quality had a 22.49 times higher risk of developing depression ( OR =22.49，95% CI =14.22~35.59, P <0.01). Conclusion Depressive symptoms among middle school students are associated with childhood maltreatment and poor sleep quality, and there is an additive interaction between childhood maltreatment and poor sleep quality on the impact of depressive symptoms.

It provides new perspectives for future research in related fields and gives more suggestions and reference for subsequent development of family enhancement programs and family-school collaborative programs.

ObjectiveTo analyze the development trajectory， research hotspots， and trends in medical humanities research in China since the new era. MethodsA search was conducted on the CNKI （China National Knowledge Infrastructure） advanced search page using the themes“medical humanities”or “humanistic medicine，”retrieving a total of 5，758 articles. After applying specific screening criteria， 5，095 articles were included in the analysis. Citespace6.1.R6 was used to visualize and analyze the authors， institutions， and keywords of the 5，095 articles. ResultsSince the new era， the volume of publications on medical humanities in China has shown an overall upward trend， with limited collaboration between core institutions and core authors. The research content of medical humanities has evolved from broad to specific， from abstract to concrete， and from theoretical to practical. ConclusionThe development of medical humanities research in China has generally gone through three stages： defining related concepts， integrating medical humanistic spirit into clinical practice， and applying empirical methods. Narrative medicine， ideological and political education in curricula， and medical humanities education are potential future research directions.

OBJECTIVE To investigate the reference range of tacrolimus blood concentration in children with Henoch- Schonlein purpura nephritis （HSPN） and analyze the factors affecting the blood concentration， in order to provide a reference for rational use of the drug in clinic. METHODS Clinical data of children with HSPN who were treated with tacrolimus and regularly monitored for blood concentration at the Children’s Hospital Affiliated to Kunming Medical University were retrospectively collected from January 2018 to January 2024. The threshold of effective concentration of tacrolimus was determined by the receiver operating characteristic curve of the subjects. The clinical efficacy of tacrolimus in different concentrations and the incidence of adverse drug reaction （ADR） were compared to determine the reference range of tacrolimus blood concentration. The factors influencing the blood concentration were analyzed by one-way and multiple linear regression. RESULTS A total of 97 pediatric patients were included， and their tacrolimus blood concentrations were monitored 203 times， the blood concentration was 4.26 （2.47， 6.34） ng/mL. The area under the receiver operating characteristic curve of the subjects was 0.723 （95%CI：0.596-0.850， P＜ 0.01）， which corresponded to an effective threshold of 2.19 ng/mL. The clinical efficacy in pediatric patients with tacrolimus blood concentrations of 3-＜5 ng/mL， 5-＜10 ng/mL， and ≥10 ng/mL was significantly higher than that of children with concentrations ＜3 ng/mL （P＜0.05）. Additionally， the overall incidence of ADR in children with concentrations of 5-＜10 ng/mL and ≥10 ng/mL was significantly higher than that in children with concentrations ＜3 ng/mL and 3-＜5 ng/mL （P＜0.05）. The impact of body mass index and CYP3A5 genotype on the blood concentration of tacrolimus was statistically significant （P＜0.05）. CONCLUSIONS When using tacrolimus to treat HSPN in children clinically， the reference range for blood concentration is 3 to 5 ng/mL； body mass index and CYP3A5 genotype are factors that influence the blood concentration of tacrolimus.

Objective: To investigate the clinicopathological characteristics and surgical outcomes of adrenal hemolymphangioma,so as to enhance the understanding of this disease. Methods: Clinical and pathological data of 8 patients with adrenal hemolymphangioma admitted to the Department of Urology of our hospital during Jan.2013 and Dec.2022 were retrospectively analyzed,and relevant literature was reviewed. Results: The patients included 5 males and 3 female,median age 54(25-75) years.Adrenal hemolymphangioma was detected in all patients in physical examinations without obvious symptoms.And 4 of the patients had a history of hypertension.Adrenal function test results showed no abnormalities.A total of 9 tumors were identified by imaging examination,including 1 unilateral multiple and 7 unilateral solitary tumors,with a median diameter of 3.6(1.0-5.4) cm.Posterior laparoscopic adrenal tumor resection was performed in 7 cases and robot-assisted laparoscopic adrenal tumor resection in 1 case；all of the tumors were completely removed.The median operation time was 77(53-115) min,median intraoperative blood loss 7.5(2.0-20.0) mL,and median postoperative hospital stay 4(1-7) d.Postoperative pathology showed interwoven deformed and dilated blood vessels and lymphatic vessels in the cystic tumors,with a large amount of lymphoid fluid,lymphocytes and red blood cells.Chronic lymphocyte infiltration was visible between the tube walls.The cystic cavity was partially connected,with flat endothelial cells lining.The pathological diagnosis was adrenal hemolymphangioma.During the median follow-up of 53.5(12.0-106.8) months,all patients recovered well,with stable blood pressure and no tumor recurrence or metastasis. Conclusion: Adrenal hemolymphangioma has no specific clinical symptoms.As adrenal functional tests show no obvious abnormalities,the diagnosis depends on pathological examinations.Popsterior laparoscopic or robot-assisted laparoscopic resection has good efficacy and prognosis.

Objective: To analyze the trajectories of body mass index for age z-score (BAZ) and its influencing factors among children with congenital hypothyroidism (CH) based on latent class growth modeling (LCGM), so as to provide the evidence for improving treatment measures and optimizing growth management among children with CH. Methods Children with CH aged 0 to 3 years from the Newborn Disease Screening Center of Shanxi Children's Hospital (Shanxi Maternal and Child Health Hospital) between 2017 and 2022 were selected as the research subjects. Basic information, height and weight data from 3 to 36 months of age, age at treatment initiation, thyroid-stimulating hormone (TSH) levels at diagnosis, and family information were retrospectively collected. BAZ for children with CH at each month of age was calculated based on the WHO Child Growth Standards. The trajectories of BAZ were analyzed using LCGM, and factors affecting the trajectories of BAZ among children with CH were analyzed using a multinomial logistic regression model. Methods: Children with CH aged 0 to 3 years from the Newborn Disease Screening Center of Shanxi Children's Hospital (Shanxi Maternal and Child Health Hospital) between 2017 and 2022 were selected as the research subjects. Basic information, height and weight data from 3 to 36 months of age, age at treatment initiation, thyroid-stimulating hormone (TSH) levels at diagnosis, and family information were retrospectively collected. BAZ for children with CH at each month of age was calculated based on the WHO Child Growth Standards. The trajectories of BAZ were analyzed using LCGM, and factors affecting the trajectories of BAZ among children with CH were analyzed using a multinomial logistic regression model. Results: A total of 299 children with CH were included. There were 140 boys (46.82%) and 159 girls (53.18%). The median of BAZ was 0.50 (interquartile range, 1.68). The LCGM analysis categorized the subjects into three groups: the persistent high-growth pattern group with 24 cases (8.03%), the slow-growth pattern group with 39 cases (13.04%), and the appropriate-growth pattern group with 236 cases (78.93%). Multinomial logistic regression analysis showed that compared to the children with CH in the appropriate-growth pattern group, those who started treatment at the age of 30 to 60 days (OR=0.109, 95%CI: 0.016-0.732; OR=0.166, 95%CI: 0.032-0.852) had a lower risk of persistent high-growth and slow-growth patterns; CH children with TSH levels of 50 to 150 mIU/L at diagnosis (OR=3.554, 95%CI: 1.201-10.514) and those whose paternal had a senior high school/technical secondary school education (OR=2.975, 95%CI: 1.003-8.823) exhibited a higher risk of the persistent high-growth pattern. Conversely, CH children whose paternal reproductive age was 30 to 35 years (OR=0.166, 95%CI: 0.034-0.806) had a lower risk of the persistent high-growth pattern. Conclusions The BAZ trajectory of children with CH aged 0 to 3 years exhibited three patterns: persistent high-growth, slow-growth, and appropriate-growth. The persistent high-growth and slow-growth patterns were associated with treatment timing, TSH levels at diagnosis, paternal reproductive age, and paternal education level. It is recommended to strengthen early treatment interventions and provide family follow-up guidance.

Objective: To investigate the epidemiological characteristics of pertussis in Harbin City from 2015 to 2024, so as to provide the basis for formulating pertussis prevention and control measures. Methods: The incidence data of pertussis in Harbin City from 2015 to 2024 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System, and the vaccination data were collected through the Immunization Program Information System of Heilongjiang Province. Descriptive epidemiological methods were used to analyze the temporal, regional and population distribution characteristics of pertussis incidence as well as the immunization history of pertussis cases. Results: A total of 417 cases of pertussis were reported in Harbin City from 2015 to 2024, with an average annual reported incidence of 0.41/100 000. The reported incidence increased from 0.18/100 000 in 2015 to 0.64/100 000 in 2024, showing an overall upward trend (P<0.05). The peak incidence period was from August to November, with 253 cases, accounting for 60.67%. The average annual reported incidences of pertussis in Shuangcheng District, Nangang District and Daoli District were relatively high, at 1.09/100 000, 0.93/100 000 and 0.52/100 000, respectively. There were 223 male cases and 194 female cases, with a male-to-female ratio of 1.15∶1. The average annual reported incidence of pertussis was 0.45/100 000 in males and 0.39/100 000 in females, with no statistically significant difference (P>0.05). Cases were predominantly distributed among children under 6 months and those aged 6 to under 10 years, with 176 and 144 cases, accounting for 42.21% and 34.53% respectively. The majority of cases were scattered children, with 266 cases (63.79%). There were 175 cases (41.97%) without diphtheria-tetanus-pertussis (DTP) vaccine and 172 cases (41.25%) who had completed the full course of immunization. Conclusions The incidence of pertussis in Harbin City showed an upward trend from 2015 to 2024. Autumn was identified as the peak season for disease onset. Shuangcheng District and Nangang District were the high-incidence areas. Children under 6 months, those aged 6 to under 10 years, scattered children, and those who had not received the DTP vaccine were the high-risk groups. It is recommended to improve pertussis surveillance strategies and strengthen childhood immunization programs.

INTRODUCTION: Odour recognition is influenced by culture. Odour identification tests need to be adapted to a population to accurately assess olfactory function. This study's objectives were to validate the Singapore version of the Sniffin' Sticks (SS-Sg) and a locally-developed odour recognition test (Scentsor) for Singapore. METHOD: This prospective study was performed in 3 otolaryngology outpatient clinics in 3 phases (1 May to 15 November 2024). Phase 1 was a survey evaluation of 93 odour descriptors to identify familiar odour descriptors to be used in the tests (n=414); Phase 2 evaluated and finalised SS-Sg and Scentsor to ensure test odours were recognised by ≥75% of healthy controls (n=130); and Phase 3 validated both tests on healthy controls (n=473) to obtain normative data, to determine test-retest reliability (n=50), and to assess the ability to distinguish patients with olfactory loss (n=67). RESULTS: In Phase 1, the unmodified SS blue and purple sets had 15/32 (46.9%) unfamiliar test odours and 25 unfamiliar distractors combined. In Phase 2, after modification, all odours in SS-Sg and Scentsor were correctly identified by ≥75% of controls. In Phase 3, normative data (age 21-83 years) was obtained. Both tests had good test-retest reliability (Pearson's correlation coefficient of 0.88 with<0.001 for SS-Sg; and at 0.90 with<0.001 for Scentsor). Both tests differentiated among normosmia, hyposmia and anosmia (SS-Sg scores: 12.6 [±2.4] versus [vs] 9.8 (±3.2) vs 6.0 [±2.3] respectively,<0.001; Scentsor scores: 14.3 [±1.8] vs 11.3 [±2.8] vs 5.8 [±3.4] respectively,<0.001). CONCLUSION SS-Sg and Scentsor have been validated to assess olfaction in Singapore.

BACKGROUND: The incidence of leptomeningeal metastasis (LM) in patients with advanced non-small cell lung cancer (NSCLC) is increasing gradually. However, it poses therapeutic challenges due to limited effective interventions. Intrathecal Pemetrexed (IP) holds broad application prospects in the therapeutic domain of LM. This study aims to evaluate the efficacy, safety, and optimal combination strategies of IP in NSCLC-LM patients with epidermal growth factor receptor (EGFR) mutation-positive status, with the aim of providing real-world data support for exploring more precise personalized treatment strategies for these patients. METHODS: 104 EGFR-mutated NSCLC-LM patients who received IP treatment at Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School from January 2018 to June 2024 were analyzed retrospectively. Clinical parameters, treatment regimens, and survival outcomes were collected. The overall survival (OS), progression-free survival (PFS), clinical response rate and adverse events (AEs) were evaluated. RESULTS: The cohort demonstrated a median PFS of 9.6 months and OS of 13.0 months with 6-month and 1-year OS rates of 80.8% and 56.5%, respectively. Clinical response was observed in 77.9% of patients. The common AEs were myelosuppression (58.7%) and elevation of hepatic aminotransferases (25.0%). Nine (8.7%) patients experienced grade 4 myelosuppression and recovered to normal after receiving symptomatic treatment. Subgroup analyses revealed prolonged OS in patients with Karnofsky performance status (KPS) ≥60 versus <60 (14.4 vs 9.0 months, P=0.0022) and those receiving Bevacizumab therapy versus not (19.2 vs 10.5 months, P=0.0011). CONCLUSIONS IP exhibits promising efficacy and manageable toxicity in EGFR-mutated NSCLC-LM patients. When combined with Bevacizumab, it exerts synergistic antitumor effects with the potential to further improve clinical outcomes.
