Objective: To explore the relationship between non suicidal self injury (NSSI) behavior and serum lipid levels as well as thyroid function among college students with depression. Methods: A total of 169 college students with depression in the psychiatry departments of tertiary hospitals (grade 3A and 3B) in Ningbo from December 2023 to April 2025 were selected. The Adolescent Self injury Scale (ASIS) was used to assess the presence of NSSI, and participants were accordingly divided into a NSSI group ( n =51) and a non NSSI group ( n =118). General demographic data (including gender, age, and family situation) were collected from both groups. Blood tests were performed to measure lipid profiles [triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C)] and thyroid hormones [triiodothyronine (T3), thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH)]. Multivariate Logistic regression was employed to analyze risk factors for NSSI, and receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of serum lipid and thyroid hormone levels for NSSI occurrence in college students with depression. Results: The levels of TC, LDL-C, and TSH in the NSSI group were (4.02±0.73) mmol/L, (2.32±0.36) mmol/L, and (6.57±1.95) mU/L , which were significantly higher than those in the non NSSI group [(3.41±0.56) mmol/L, (2.00±0.27) mmol/L, and ( 4.48± 1.09) mU/L, respectively] ( t =5.32, 5.60, 7.20, all P <0.05). Logistic regression analysis revealed that college students from single parent/reconstituted families, those who had experienced school bullying, and those with higher levels of TC, LDL-C, and TSH had a significantly increased risk of engaging in NSSI ( OR =5.22, 6.12, 5.90, 83.64, 3.64, all P <0.05). ROC curve analysis demonstrated that the combined detection of TC, LDL-C, and TSH had high diagnostic efficacy for predicting NSSI in college students with depression, with a sensitivity of 86.3% and a specificity of 94.9%. Conclusions NSSI behavior in college students with depression is associated with serum lipid levels and thyroid function. These biomarkers may serve as useful reference indicators for assessing the conditions of these patients.

Objective: To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies. Methods: From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects. Results: Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05). Conclusion Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

With the continuous refinement of China's rare disease prevention and treatment policies, the diagnosis and treatment capacity for rare diseases in China has been steadily improved; however, delayed diagnosis, inadequate transition of care, and poor continuity of long-term management remain common, particularly in pediatric rare diseases. Pediatric rare diseases often arise during critical developmental stages and exhibit age-dependent phenotypic evolution, such that diagnostic delays may lead to the missing of critical intervention windows. As the leading institution of the Hubei Provincial Rare Disease Medical Center and the Rare Disease Quality Control Center, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology (hereinafter referred to as "Tongji Hospital") has established and implemented a rare disease discipline cluster model centered on platform convergence and specialty clustering. This model centers on the whole-life-cycle management needs of pediatric rare diseases, and constructs a systematic operational framework covering technical and data support, platform governance, specialized cluster operation, as well as regional and policy coordination. By summarizing the organizational pathway and practical effects of the rare disease discipline cluster construction at Tongji Hospital, this paper aims to provide a reference for general hospitals in promoting the development of rare disease diagnosis and treatment systems.

Respiratory syncytial virus (RSV) is the most common respiratory pathogen in infants and young children, which can lead to severe pneumonia and even death. Early diagnosis and intervention are crucial for reducing complications and sequelae and improving prognosis. This study presents the complete diagonsis and treatment process of a typical severe RSV pneumonia patient. For high-risk children, the condition can progress rapidly after RSV infection, and may present with respiratory failure and multiple extrapulmonary complications, such as heart failure, liver and kidney function impairment, coagulation dysfunction. After active symptomatic and supportive treatment, the prognosis is generally good. RSV infection will not lead to long-lasting immunity, but as the child grows older and their immune function gradually improves, the condition of a secondary infection is generally relatively mild. Currently, there are no specific antiviral drugs or safe and effective vaccines for RSV. Long-acting monoclonal antibodies are one of the effective means to prevent RSV infection in infants and young children and have been approved for use in China.

Background::Intrauterine growth restriction (IUGR) is associated with adverse metabolic outcomes during adulthood. Histone modifications and changes in DNA methylation-affected genes are important for fetal development. This study aimed to investigate the epigenetic mechanisms in IUGR.Methods::IUGR models were established in Sprague–Dawley rats using a maternal nutritional restriction approach during pregnancy. The abundance of insulin-like growth factor 2 (IGF2), phosphoinositide 3-kinase (PI3K), AKT serine/threonine kinase 2 (AKT2), and peroxisome proliferators-activated receptor gamma coactivator 1 alpha (PGC-1α) was examined by real-time polymerase chain reaction (RT-PCR) and Western blotting analysis. Chromatin immunoprecipitation RT-PCR was employed to analyze histone modification in CCCTC-binding factor (CTCF) 1–4 binding sites of the Igf2/H19 imprinting control region (ICR). The methylation states of CTCF1–4 binding sites were studied by pyrosequencing. Results::The IUGR models were constructed successfully. Igf2 mRNA abundance in the placenta, fetal liver, and newborn liver was decreased in the IUGR group ( P <0.01). Meanwhile, as compared with the control group, the expression levels of AKT2, PI3K, and PGC-1α were lower in newborn and 8-week-old livers in the IUGR group ( P <0.05). In addition, knocking down Igf2 reduced the protein expression levels of AKT2-phosphorylation and PGC-1α ( P <0.05). In CTCF binding sites 1-4 of the Igf2/ H19 ICR, acetylated histones H3 (AcH3) enrichment was significantly lower in CTCF1-3 in newborn and 8-week-old IUGR rats. Histone H3 tri-methylated lysine 4 (H3K4me3) enrichment was significantly lower in the CTCF1–4 of newborn and 8-week-old IUGR groups ( P <0.01). H3K9me2 enrichment was significantly higher in the IUGR group ( P <0.01). The CpG dinucleotide methylation levels of CTCF1 and CTCF3, but not those of CTCF2 and CTCF4 binding sites in IUGR rat fetal, 4-week old, and 8-week-old livers decreased significantly ( P <0.05). Conclusion::The methylation status and histone modification in the Igf2/H19 ICR are related to growth and lipid metabolism via the PGC-1α/PI3K/AKT2 pathway in IUGR rats.

Objective To evaluate the effectiveness of therapeutic dentures with flat tables in edentulous patients with neuromuscular dysfunction.Methods Thirteen edentulous patients with neuromuscular dysfunction participated in this study.Initially,conventional complete dentures were fabricated using the biofunctional prosthetic system(BPS)method and delivered to the patients.The satisfaction questionnaire and oral health-related quality of life(OHRQoL)were assessed on the day of delivery and again two weeks later.The pa-tients whose grades of over-all satisfactory fewer than 8 were participated in neuromuscular training with therapeutic dentures.Subse-quently,4 mm of the occlusal surfaces of the mandibular artificial posterior teeth were removed to create flat tables.Once the mandibu-lar position was stabilized,new mandibular denture was fabricated and the same assessments were conducted on the day of delivery.Results In edentulous patients with neuromuscular dysfunction,there were no significant improvements in satisfaction,or OHRQoL on the day of delivery or two weeks later.However,significant improvements in satisfaction and OHRQoL were observed after the defin-itive dentures delivered following neuromuscular training(P＜0.05).Conclusion Thetherapeutic dentures with flat tables can improve the neuromuscular function in edentulous patients with neuromuscular dysfunction,significantly increasing their satisfaction in the den-tures,while also enhancing their quality of life.

Objective To investigate the application of targeted next-generation sequencing test(tNGS)in detecting patho-gens and drug resistance genes in the diagnosis and treatment of Mycoplasma pneumoniae pneumonia(MPP)in chil-dren.Methods The clinical data of children diagnosed with MPP and hospitalized in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from July 2022 to December 2023 were analyzed.The differences of MP se-quence detected by tNGS in children of different gender,age,course,and clinical features were compared.The performance of tNGS in detecting macrolides resistance genes was assessed.The optimal prediction cut-off value of MP resistance gene was ex-plored by ROC.Results A total of 497 cases were included,including 257(51.7％)male and 240(48.3％)female.The age dis-tribution was from 3 months to 13 years old[(6.08±2.68)years old in average],and the average durations of fever and cough were(6.04±3.42)and(7.46±5.54)days,respectively.MP was detected in all patients by tNGS method.There was no signifi-cant difference in different gender or age groups.The MP sequence count in patients with positive nucleic acid was significantly higher than that in patients with negative nucleic acid.The MP sequence count in lower respiratory specimens was significantly higher than that in upper respiratory specimens.MP sequence count in severe cases was significantly higher than that in non-se-vere cases,but there was no significant difference between patients with or without pulmonary complications and refractory or non-refractory cases.The overall diagnostic sensitivity of tNGS for detecting MP drug-resistant genes was 92.8％,specificity was 27.8％,PPV was 48.3％,NPV was 84.2％,and the mutation site was 23S rRNA:A2063G.The ratio of MP pathogenic se-quence to drug-resistant gene sequence was 6.83,which was the best cut-off value for predicting drug resistance.The negative predictive value was higher when the MP pathogenic sequence ratio was greater than 6.83.Conclusion tNGS has the value in early diagnosis of MPP.The MP sequence counts may have a guiding value in predicting disease severity.The negative predictive value is higher in drug-resistant gene detection.

Objective:To evaluate the safety and efficacy of accelerator-based boron neutron capture therapy (AB-BNCT) in the treatment of recurrent and refractory malignant tumors.Methods:The data of 14 patients admitted to Xiamen Humanity Hospital from September 2022 to April 2023 were prospectively collected, including 7 patients with primary brain malignancies and 7 patients with locally recurrent inoperable head and neck malignancies. All patients received intravenous infusion of boron drug (NBB-001, p-dihydroxyborylphe nylalanine, a patented freeze-dried formulation) at a total nominal dosage of 500 mg/kg (11 patients) or 750 mg/kg (3 patients), and were irradiated with neutrons (operating with NeuPex system). Adverse events after treatment were recorded and assessed. The primary efficacy endpoint was the 90 d objective response rate (ORR), while the secondary endpoints included progression-free survival (PFS) and complete response rate (CRR). Data were compiled and analyzed by SAS 9.4 software. The rate and 95% CI were calculated using Clopper-Pearson method. Results:The median dose delivered to 80% of the target volume (D 80%) was 16.80 GyE (range: 8.93-23.79 GyE). The most common adverse reactions were hyperamylasemia, alopecia, and hyperprolactinemia. Five patients experienced 8 cases of grade 3 or above adverse events, including 1 case of grade 4 acute kidney injury and 7 cases of grade 3 adverse events. All adverse events were recovered after observation or treatment. At 90 d after treatment, the ORR of all patients was 9/14 (64%, 95% CI: 35%-87%), disease control rate (DCR) was 10/14 (71%, 95% CI: 42%-92%), CRR was 2/14 (14%, 95% CI: 2%-42%); and the best overall response during the entire course included an ORR of 10/14 (71% ,95% CI: 42%-92%), DCR of 13/14 (93%, 95% CI: 66%-100%), and CRR of 3/14 (21% ,95% CI: 5%-51%). The 1-year survival rate for head and neck malignancies was 71.4%, and the 2-year survival rate was 42.8%. The 1-year survival rate for recurrent brain malignancies was 42.8%. Conclusion:AB-BNCT demonstrates favorable safety and promising efficacy in treating primary brain malignancies and recurrent/refractory head and neck malignancies, representing a potential therapeutic option.

Objective:To assess the efficacy and safety profile of antaitasvir phosphate combined with yiqibuvir in the treatment of chronic hepatitis C (CHC) of various genotypes, without cirrhosis or with compensated cirrhosis.Methods:394 cases with CHC from 22 centers were collected from October 2021 to April 2023. They were randomly assigned to receive either the experimental drugs (antaitasvir phosphate 100 mg+yiqibuvir 600 mg) or placebo treatment in a 3∶1 ratio. The patients were administered drugs once a day for 12 consecutive weeks, and then followed up for 24 weeks after treatment cessation. All subjects were unblinded at the four-week follow-up following drug discontinuation, with the experimental drug group continuing to complete subsequent post-discontinuation follow-up. The placebo group was switched to receive the experimental drugs for a repeated 12-week treatment period and followed up for another 24 weeks after discontinuation of the drug (placebo delayed treatment phase).The sustained virologic response rate (SVR12) was observed for subjects in the double-blind phase and the placebo delayed-treatment phase at 12 weeks after treatment cessation.Virological resistance analysis was performed on subjects who failed treatment. The primary efficacy endpoint was SVR12. The number and percentage of subjects who achieved "HCV RNA
