Objective: To explore the association between peer victimization and psychotic like experiences (PLEs) among junior high school students, so as to provide a scientific basis for preventing adolescent PLEs. Methods: In January 2024, a method of combining convenient sampling with cluster sampling was used to survey 2 760 students from two ordinary junior high schools in southern Anhui Province (Susong Country,Anqing City). The Community Assessment of Psychic Experiences (CAPE) and the Adolescent Peer Bullying Scale were employed to assess PLEs with different symptoms and peer victimization (verbal, physical, relational, and cyberbullying). Multivariate Logistic regression models analyzed the associations of different types peer victimization and PLEs with different symptoms. Results: The prevalence of PLEs was 17.5%, with delusional (15.4%) and hallucinatory (7.4%) symptoms being most common. Peer victimization was reported by 51.3% of students (49.6% victims, 19.5% perpetrators), with verbal victimization being most frequent (42.4% victims, 15.5% perpetrators) and cyberbullying least frequent (6.0% victims, 1.9 % perpetrators). Compared to students without bullying,students exposed to bullying showed significantly higher rates of delusional ( χ 2=29.09-127.22), hallucinatory ( χ 2=27.23-72.29), and overall PLEs ( χ 2=34.32-127.25) (all P <0.01). After adjusting for relevant confounding factors,the multiple Logistic regression model revealed verbal victimization increased risks of delusions ( OR=1.59, 95%CI =1.22-2.09), hallucinations ( OR=1.94, 95%CI =1.33-2.84), and overall PLEs ( OR=1.62, 95%CI = 1.26- 2.09); relational victimization was associated with delusions ( OR=1.83, 95%CI =1.40-2.39) and PLEs ( OR=1.65, 95% CI = 1.28-2.13); physical victimization correlated with hallucinations ( OR=1.64, 95%CI =1.12-2.40) and PLEs ( OR=1.41, 95%CI =1.06-1.87) (all P <0.05). Conclusion Specific types of peer victimization are differentially associated with PLEs, with relational victimization demonstrating the strongest association.

Objective: To analyze the timeliness of antir-etroviral therapy (ART) and its influencing factors among newly reported HIV/AIDS cases in Wenzhou City, Zhejiang Province from 2016 to 2023, so as to provide a reference for improving the ART effect of HIV/AIDS cases. Methods: Newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were selected as the research subjects. Demographic information, the situation of the first CD4+ T lymphocyte (CD4 cell) test, baseline CD4 cell count, and ART situation were collected through the Chinese Disease Prevention and Control Information System. The timely rate of ART was analyzed, and the influencing factors for timely ART among HIV/AIDS cases were analyzed using a multivariable logistic regression model. Results: A total of 4 500 newly reported HIV/AIDS cases in Wenzhou City from 2016 to 2023 were included, among which 3 679 were males, accounting for 81.76%, and 821 were females, accounting for 18.24%. The median age was 46.24 (interquartile range, 26.23) years. Among these cases, 3 606 received timely ART, with a timely rate of 80.13%. The timely rate of ART increased from 57.54% in 2016 to 91.97% in 2023 (P<0.05). Multivariable logistic regression analysis showed that unmarried/divorced/widowed (OR=0.769, 95%CI: 0.641-0.922), detainees (OR=0.492, 95%CI: 0.269-0.900), untimely first CD4 cell test (OR=0.278, 95%CI: 0.234-0.330), baseline CD4 cell count ≥200 cells/µL (OR=0.709, 95%CI: 0.595-0.843) or undetected (OR=0.131, 95%CI: 0.080-0.213) were associated with a lower timeliness for ART among HIV/AIDS cases. Conclusion From 2016 to 2023, the timely rate of ART among newly reported HIV/AIDS cases in Wenzhou City showed an upward trend, which was mainly affected by marital status, case source, timeliness of the first CD4 cell test, and baseline CD4 cell count.

OBJECTIVES: To evaluate the clinical efficacy of human biological dressing (human acellular dermal matrix) transplantation in the management of refractory wounds among middle-aged and elderly patients. METHODS: A retrospective observational study was conducted involving 104 middle-aged and elderly patients (74 males, 30 females; aged 56-95 years) with refractory wounds treated at the First Affiliated Hospital of Wenzhou Medical University from January 2023 to December 2024. Following debridement, wound areas ranged from 1.0 to 48.0 cm². All patients received vacuum sealing drainage for 7 days, followed by human biological dressing transplantation. Subsequently, depending on the wound condition and the patient's preference, autologous skin grafting (ASG) or wound dressing changes were employed to promote wound healing. Outcome measures included: post-human biological dressing coverage of exposed tendons/bones and occurrence of tendon infection/osteomyelitis; survival rate of ASG at postoperative day 7; healing time in patients managed with wound dressing changes alone; patient satisfaction; and changes in pain intensity, sleep disturbance, and anxiety scores assessed before and 1 month after human biological dressing transplantation using the Edmonton Symptom Assessment Scale. RESULTS: After human biological dressing transplantation, 103 patients exhibited robust granulation tissue formation achieving complete coverage of the exposed tendons/bones, with no instances of tendon/bone necrosis, infection, or osteomyelitis. Among these, 51 patients underwent successful ASG at (44.4±13.0) d post-human biological dressing transplantation (success rate 100.00%), 52 patients achieved primary wound healing through dressing changes alone within (62.6±13.4) d post-human biological dressing transplantation. One patient experienced human biological dressing dissolution and detachment due to gluteal wound infection, resulting in non-healing. The overall cure rate was 99.04%. Patient satisfaction survey showed that 95 patients were very satisfied, 8 were satisfied, and 1 was dissatisfied (satisfaction rate 99.04%). Pain, sleep disturbance, and anxiety scores at 1 month post-human biological dressing transplantation were significantly reduced compared to pre-transplantation scores (all P<0.05). CONCLUSIONS Human biological dressing transplantation demonstrate excellent outcomes in treating refractory wounds in middle-aged and elderly patients and can serve as an effective therapeutic strategy for managing refractory wounds.

The translocator protein (TSPO) positron emission tomography (PET) can noninvasively detect neuroinflammation associated with epileptogenesis and epilepsy. This study explored the role of the TSPO-targeting radioligand [¹⁸F]F-TFQC, an m-trifluoromethyl ER176 analog, in the PET neuroimaging of epileptic rats. Initially, [¹⁸F]F-TFQC was synthesized with a radiochemical yield of 8%-10% (EOS), a radiochemical purity of over 99%, and a specific activity of 38.21 ± 1.73 MBq/nmol (EOS). After determining that [¹⁸F]F-TFQC exhibited good biochemical properties, [¹⁸F]F-TFQC PET neuroimaging was performed in epileptic rats at multiple time points in various stages of disease progression. PET imaging showed specific [¹⁸F]F-TFQC uptake in the right hippocampus (KA-injected site, i.e., epileptogenic zone), which was most pronounced at 1 week (T/NT 1.63 ± 0.21) and 1 month (T/NT 1.66 ± 0.20). The PET results were further validated using autoradiography and pathological analysis. Thus, [¹⁸F]F-TFQC can reflect the TSPO levels and localize the epileptogenic zone, thereby offering the potential for monitoring neuroinflammation and guiding anti-inflammatory treatment in patients with epilepsy.
