Objective: To explore the correlation between blind box consumption and non-suicidal self-injury(NSSI) among middle school students, so as to provide new theoretical insights for the prevention of NSSI. Methods: Using stratified random cluster sampling method, 2 807 middle school students aged 11-19 years old were selected from Hunan and Gansu provinces from November 2024 to March 2025. The blind box consumption questionnaire and Functional Assessment of Self mutilation Scale were administered to collect data on students blind box consumption frequency, as well as NSSI behavior. The χ 2 test was used to compare differences in the distribution of NSSI across different groups. Multivariate Logistic regression analysis was performed to infer the correlation and gender differences. Results: A total of 15.3% of middle school students reported having at least one NSSI incident in the past year, among which the reported rates of occasional NSSI (1-4 times) and repeated NSSI (≥5 times) were 5.5% and 9.8% respectively. The results of univariate analysis showed that there was statistically significant different in NSSI distribution among groups with different blind box consumption frequencies ( χ 2=55.72, P <0.05). After adjusting for confounding factors such as age, gender, school stage, family type, discipline style, pocket money, impulsiveness and emotion management, the results of multiple Logistic regression models showed that compared with the group without blind box consumption, the risks of "occasional NSSI" and "repeated NSSI" were higher in the group with blind box consumption ( OR =1.54, 1.66), and the frequency of blind box consumption(continous variable) was positively correlated with the risks of "occasional NSSI" and "repeated NSSI" among middle school students ( OR =1.26, 1.34)(all P <0.05).After gender stratification, the consumption behavior of blind boxes and the frequency of blind box consumption (continuous variable) of boys and girls were associated with "repeated NSSI"(boys: OR =1.61, 1.32, girls: OR =1.65, 1.35), and only in the male group was a correlation between blind box consumption and "occasional NSSI" observed ( OR =2.27) (all P <0.05). Conclusion Blind box consumption may be related to NSSI among middle school students, and there are gender differences in its correlation with NSSI among middle school students.

Objective:To explore the clinical features of programmed cell death-1 (PD-1) inhibitor-associated hypophysitis and improve the understanding of the disease.Methods:For the present retrospective case series study, the clinical data of patients with PD-1 inhibitor-associated hypophysitis who were treated at the Affiliated Hospital of Hebei University and the 3rd Hospital of Hebei Medical University from January 2020 to May 2023 were collected for analysis of clinical manifestations and prognosis.Results:Fifteen cases of PD-1 inhibitor-induced hypophysitis were included, with 13 males and 2 females. The mean age of onset was (62.1±7.5) years, and the median time of onset was 6.5 (4.7, 11.6) cycles of PD-1 inhibitor. At diagnosis, 14 patients complained of gastrointestinal symptoms, and 12 patients complained of fatigue. There were 12, 1, 1, 5, and 1 cases of hyponatremia, hypokalemia, hypoglycemia, hypotension, and fever, respectively. Secondary adrenocortical insufficiency occurred in all cases. Moreover, four patients had secondary hypothyroidism, and two patients had secondary hypogonadism. Posterior pituitary hypofunction was not found. Pituitary MRI showed one case each of vacuolar sella turcica, pituitary cystic lesion, pituitary stalk slightly shifted to the left, high metabolism in the sella turcica, and pituitary abnormal signal, while no abnormalities were found in 11 cases. The follow-up time was (47.66±11.93) weeks. At the last follow-up, one patient′s serum levels of adrenocorticotropic hormone and cortisol returned to normal.Conclusions:Hypophysitis associated with PD-1 inhibitors occurs later, and gastrointestinal symptoms and fatigue are the most common clinical manifestations. PD-1 inhibitor-associated hypophysitis mainly manifests as adrenocortical hypofunction, and some cases manifest as hypothyroidism and hypogonadism. In addition, patients with PD-1 inhibitor-associated hypophysitis show no obvious imaging changes in the pituitary gland.

Objective:To evaluate the self-assessed and proxy-assessed quality of life among disabled elderly individuals aged 60 and above in Chengdu,analyze the factors influencing these assessments,and assess the consistency between these two types of outcomes and the feasibility of proxy assessments.Methods:The quality of life for disabled elderly individuals is measured using the EQ-5D-5L for both self-assessments and proxy assessments.Consistency testing is conducted using weighted Kappa and Intraclass Correlation Coefficient(ICC).Univariate and differential analyses are performed with the Mann-Whitney/Wilcoxon and Kruskal-Wallis tests,respectively.The analysis of influencing factors employs generalized linear model regression.Results:The results of proxy assessments are slightly higher than those of self-assessments.The consistency between self-assessed and proxy-assessed health utility values and EQ-VAS scores is good(with ICC values exceeding 0.7),while the consistency across various dimensions is fair to moderate(with weighted Kappa values approximately between 0.4 and 0.5).The degree of disability,economic status,outdoor activities and sleep,the relationship between caregivers and the elderly,and whether caregivers possess relevant caregiving knowledge,all have a statistically significant impact on the quality of life of disabled elderly individuals and the differences between self-assessed and proxy-assessed outcomes(P＜0.05).Conclusion:The quality of life of disabled elderly individuals is significantly lower than that of the general population.It is essential to consider various related factors to enhance the quality of life for these individuals.The EQ-5D-5L proxy assessment results from their primary caregivers can serve as a supplement to the self-assessment results of disabled elderly individuals.However,individual dimensions should be applied with caution,taking into account the characteristics and individual differences of the evaluated population,types of proxies,and measurement tools used.

In order to explore the role of BspE protein in Brucella infection,yeast two-hybrid tech-nique was used to screen host cell proteins that interact with BspE protein.The constructed BspE recombinant plasmid pGBKT7-BspE was used as bait plasmid to hybridize with the RAW264.7-cD-NA library of mouse mononuclear macrophages by yeast two-hybridization technique.The positive clones were extracted by plasmid,sequenced and co-immunoprecipitation to determine the host cell proteins that could interact with BspE.The subcellular localization of BspE proteins was analyzed by confocal laser microscopy.The physical and chemical properties,protein structure and function of BspE interacting proteins were analyzed by bioinformatics.The siRNA for one of the BspE inter-acting proteins was synthesized,the expression of its gene was silenced in HEK293T cells,and the silenced cells was infected with Brucella M5-90 and the number of intracellular bacteria was coun-ted.The results showed that the decoy plasmid pGBKT7-BspE was successfully constructed,and the plasmid could express BspE protein in yeast.Eight positive clones were obtained from the host cell genome library by yeast two-hybridization.The positive clones were identified as RBM27 and PCBP1 by sequencing,backcross and co-immunoprecipitation.Bioinformatics was used to predict the cell location,protein structure and amino acid composition of RBM27 and PCBP1.After siRNA interference,the expression level of PCBP1 was significantly decreased and the amount of M5-90 in the cell was increased.Brucellosis secreted protein BspE interacts with host proteins RBM27 and PCBPl,and PCBP1 negatively regulates the proliferation of Brucellosis.

ObjectiveTo explore the distribution characteristics of traditional Chinese medicine （TCM） syndrome elements of macroangiopathy in patients with type 2 diabetes mellitus （T2DM） and the key elements of occurrence， development and progression of disease. MethodsA multicenter cross-sectional study was conducted to enroll 445 T2DM patients from five hospitals， and according to the presence or absence of macroangiopathy， the patients were divided into a T2DM group （120 cases） and a diabetic macroangiopathy （DM） group （325 cases）. Patients in DM group were divided into grade Ⅰ， Ⅱ， Ⅲ and Ⅳ according to the peripheral vascular color Doppler ultrasound results and the vascular anomalies classification standard. The general data including gender， age， duration of T2DM and body mass index （BMI） were collected， and the data of four examinations were obtained for syndrome differentiation. According to the diagnostic criteria of TCM syndrome elements， the patients can be divided into 9 patterns including qi deficiency， blood deficiency， yin deficiency， yang deficiency， qi stagnation， blood stasis， excess heat， and excess cold. The general data and distribution of TCM syndrome elements were compared between the two groups. The distribution of TCM syndrome elements in different vascular anomalies grades in the DM group was analyzed. Logistic regression analysis was used to explore the influence of various TCM syndrome elements on the occurrence of macroangiopathy in T2DM. ResultsThere was no significant difference in gender and BMI between groups （P＞0.05）. The age and duration of diabetes in the DM group were older and longer than those in the T2DM group （P＜0.01）. With the increase of age and prolonged course of disease， the severity of diabetic macroangiopathy increases gradually （P＜0.05 or P＜0.01）. There was no significant difference in BMI and course of disease among the different TCM syndrome elements （P＞0.05）. The average age of patients with blood stasis syndrome was the oldest （P＜0.05）. There was significant difference in gender distribution between the excess heat syndrome and yin deficiency syndrome （P＜0.05）. A total of 240 TCM syndrome elements were extracted from the T2DM group， while 731 TCM syndrome elements extracted from the DM group. The top two high-frequency syndrome elements in the two groups were qi deficiency and yin deficiency， with a frequency of larger than 50%. The distribution of phlegm-damp syndrome and blood-stasis syndrome were significantly higher in the DM group than in the T2DM group （P＜0.01）. There were significant differences in the distribution of qi deficiency syndrome， yin deficiency syndrome， phlegm-damp syndrome， blood stasis syndrome， and excess heat syndrome among different grades of vascular anomalies （P＜0.01）； qi deficiency and yin deficiency were both high-frequency TCM syndrome elements in patients at grades 0 to Ⅲ； phlegm-damp syndrome increased in frequency with the progression of the disease from grades 0 to Ⅳ， and the frequency of blood stasis syndrome showed an overall upward trend. The frequency of phlegm-dampness syndrome increased from grades 0 to Ⅳ with the progression of the disease， and the frequency of blood stasis syndrome showed an overall upward trend. Logistic regression analysis showed that phlegm-damp syndrome and blood stasis syndrome were important TCM syndrome elements related to the vascular anomalies degree of macrovascular disease in T2DM （P＜0.05 or P＜0.01）. ConclusionQi deficiency and yin deficiency are the basic TCM syndrome elements throughout the whole process of T2DM and diabetic macrovascular disease. Phlegm-damp and blood stasis are related to the degree of vascular anomalies in diabetic macrovascular disease and are the key TCM syndrome elements in the progression of macroangiopathy in T2DM.
