Background Non-suicidal self-injury(NSSI)behavior has become a major public health concern and can have significant implications for the physical and mental health of adolescents.Peer victimization is a risk factor for adolesents to have NSSI behavior,so exploring the relationship and underlying mechanism between peer victimization and NSSI functions will provide a promising strategy for the prevention and intervention of NSSI behavior.Objective To investigate the relationship between peer victimization and NSSI functions in adolescents with unipolar and bipolar depression,so as to provide references for the intervention of NSSI behavior in adolescent patients with unipolar and bipolar depression.Methods Using multi-stage stratified sampling,940 adolescents with unipolar and bipolar depression who met the Diagnostic and Statistical Manual of Mental Disorders,fifth edition(DSM-5)criteria for bipolar depressive episodes or depressive disorders were selected from 14 psychiatric hospitals in China.All participations were assessed using Chinese version of the Functional Assessment of Self-Mutilation(C-FASM),Multidimensional Peer-Victimization Scale(MPVS),UCLA Loneliness Scale(UCLA-LS)and Patient Health Questionnaire-9 item(PHQ-9).Pearson correlation coefficient was to assess the correlation among above scales,and the model fit and path coefficients for mediation were analyzed with model 4 in Process 4.0 for SPSS.Results A total of 698(74.26%)adolescents with unipolar and bipolar depression completed the questionnaire survey.NSSI behavior was detected in 374 patients(53.58%).Among adolescents with unipolar and bipolar depression and NSSI behavior,MPVS total score was positively correlated with the scores of NSSI emotion regulation function,attention-seeking function and social avoidance function in C-FASM(r=0.104,0.130,0.266,P<0.05 or 0.01),UCLA-LS score also yielded a positive correlation with the scores of NSSI emotion regulation function,attention-seeking function and social avoidance function in C-FASM(r=0.321,0.112,0.246,P<0.05 or 0.01),and UCLA-LS score was positively correlated with MPVS total score(r=0.241,P<0.01).Loneliness demonstrated a complete mediating role in the relationship between peer victimization and emotion regulation function,with an indirect effect value of 0.033(95%CI:0.019～0.050)and an effect size of 73.33%.A partial mediating effect of loneliness was also observed for the relationship between peer victimization and social avoidance function,with an indirect effect value of 0.016(95%CI:0.007～0.025)and an effect size of 17.98%.Conclusion Loneliness may act as a mediator in the relationship between the peer victimization and the NISS emotion regulation and social avoidance functions in adolescents with unipolar and bipolar depression and NSSI behaviors.

Objective:To understand the relationship between unhealthy lifestyle and hyperuricemia, as well as the modification effects of hypertension and dyslipidemia in occupational population and provide a theoretical basis for the prevention of hyperuricemia.Methods:A cross-sectional survey design was adopted, based on baseline data from the Southwest Occupational Population Cohort from China Railway Chengdu Group Co., Ltd., which included the population in 28 prefectures from Sichuan Province and Guizhou Province, and 33 districts (counties) from Chongqing Municipality between October and December 2021. This study collected the information about the demographics characteristics, lifestyles, and prevalence of chronic non-communicable diseases of the study subjects through questionnaire, physical measurement and laboratory biochemical test. The unhealthy lifestyle score was scored based on smoking, alcohol consumption, dietary patterns, physical activity, and low weight or overweight, with higher scores being associated with more unhealthy lifestyles. The multivariate logistic regression model was used to analyze the relationship between unhealthy lifestyle score, smoking, alcohol consumption, other factors and hyperuricemia, and the stratified analysis was used to explore the modification effect of hypertension and other diseases on the relationship between unhealthy lifestyle and hyperuricemia.Results:A total of 11 748 participants were included in this study, the prevalence of hyperuricemia was 34.4%. Multivariate logistic regression model showed that current/previous smoking, current/previous alcohol consumption and BMI abnormality were risk factors for hyperuricemia, and the unhealthy lifestyle score showed a "cumulative" effect on the risk for hyperuricemia, with higher score increasing the risk of hyperuricemia, and the OR increased from 1.64 (95% CI: 1.34-2.00) to 2.89 (95% CI: 2.39-3.50). Stratified analysis showed that unhealthy lifestyles had a greater impact on the risk for hyperuricemia in people with hypertension and dyslipidemia. Conclusions:The coexistence of multiple unhealthy lifestyles might increase the risk of hyperuricemia, and this effect was stronger in participants with hypertension and dyslipidemia. Timely correction of unhealthy lifestyles, and control of hypertension and dyslipidemia might reduce the risk for hyperuricemia.

The emergence of high virulent mutant strains of infectious bursal disease virus(IBDV)becomes a serious threat to the poultry industry.However,the live attenuated IBDV vaccine can potentially revert to a virulent strain.Therefore,it is a necessary to develop safe and effective IB-DV-associated vaccines.The construction of a recombinant Marek's disease(MD)vaccine strain,CVI988,expressing the IBDV VP2 protein,can protect against disease induced by both IBDV and Marek's disease virus(MDV).Here,the IBDV-VP2 gene was integrated into the UL55 locus of CVI988 by bacterial artificial chromosome(BAC)technique,resulting in the recombinant virus CVI988 BAC-VP2.The recombinant virus was characterized by PCR,IFA and subsequently the bi-ological properties of the recombinant virus were investigated.The results showed that the recom-binant virus CVI988 BAC-VP2 was successfully rescued.The VP2 protein stably expressed in chick-en embryo fibroblasts(CEF).The growth kinetics and plague size assays showed that there was comparable replication ability between recombinant virus and parental virus.This study provides the basis for the development of a low-cost vaccine against both IBDV and MDV infections.

Objective:To analyze the clinical characteristics of elderly patients with papillary thyroid cancer(PTC)by age grouping.Methods:The patients were divided into three groups according to age at diagnosis: old(≥60 years, 90 cases), middle(40-59 years, 359 cases)and young patients(<40 years, 203 cases). The clinical data of 652 patients with PTC who were admitted to the Department of Thyroid Surgery of Beijing Hospital from December 2019 to December 2021 were retrospectively analyzed.The patients were divided into elderly group(≥60 years old, 90 cases), middle-aged group(40-59 years old, 359 cases)and young group(<40 years old, 203 cases). The clinical characteristics, ultrasound characteristics and invasion-related factors of patients in different groups were analyzed by statistical methods.Results:Compared with the young and middle-aged group, the elderly patients with PTC had a higher proportion of microcarcinoma(75.6%, 75.2%, 61.4%, χ2=13.054, P=0.001), less cervical lymph node metastasis(24.4%, 34.3%, 58.1%, χ2=41.650, P<0.001), and lower proportion of metastatic lymph nodes(0.08, 0.14, 0.24, χ2=40.618, P<0.001). There was no significant difference in tumor location and extra glandular invasion among the three age groups(35.56%, 36.2%, 38.4%, χ2=0.959, P=0.545). Conclusions:Compared with the young and middle-aged groups, PTC showed low invasiveness in the elderly population.In addition to surgical treatment, for elderly patients with low-risk clinical characteristics, it is worth performing a further study on whether careful observation or palliative treatment can be selected after comprehensive evaluation.

Objective: To investigate the clinical manifestations, pathological features, and treatment of oral and maxillofacial pyogenic granulomas induced by camrelizumab. Methods: A case of pyogenic granuloma of the gums and lips caused by camrelizumab was reported along with a literature review. Results: After 4 months of treatment with camrelizumab for liver cancer, the patient developed systemic reactive capillary hyperplasia (RCH), followed by multiple masses on the lower lip and gingiva. After periodontal therapy, the masses on the lower lip and the gingiva were removed, and camrelizumab administration was stopped. The pathological result was gingival pyogenic granuloma/granulomatous hemangioma. No new masses were found in the oral cavity during postoperative follow-up. A review of the literature showed that RCH is the most common adverse drug reaction to camrelizumab but it occurs infrequently in the oral cavity. At present, the etiology of RCH has not been clarified, but the research has shown that camrelizumab may trigger tissue proliferation into hemangiomas by activating vascular endothelial cells, and the combined use of camrelizumab is safer than single use. RCH is self-limiting and most cases resolve spontaneously after discontinuation of the drug. If the mass causes dysfunction, surgical excision is feasible. Conclusion Camrelizumab can cause oral and maxillofacial reactive capillary hyperplasia complicated by pyogenic granuloma.
