Objective: To determine the internal relationships pf perceived discrimination and rejection sensitivity with social adjustment among college students with left behind experiences, so as to provide a reference for targeted prevention and intervention strategies for social adjustment issues in this population. Methods: A cluster random sampling method was used to select 2 999 college students from 3 universities in Qiqihar and Daqing, Heilongjiang Province. In October, 2024 (T1) and April 2025 (T2), the Discrimination Perception Questionnaire of college students, Rejection Sensitivity Questionnaire, and the Chinese College Student Adjustment Scale (CCSAS) were used to assess students perceptions of discrimination, rejection sensitivity, and social adjustment levels. Independent sample t-test was used for group comparisons. Traditional cross sectional comparisons and cross sectional network analysis were performed using T1 data for the core sample of 1 080 students with left behind experiences (T1). Longitudinal network analysis was performed using paired data from T1 and T2 ( n =1 024) and a preliminary cross lagged model was used to determine the relationships between variables. Sensitivity analysis was performed by including followup data from students without left behind experiences to test the robustness of the results. Results: After gender adjustment, students with leftbehind experiences had higher scores on discrimination perception (13.14±0.16) and rejection sensitivity (92.82±0.73) compared to the non left behind group (10.25±0.12) (89.12±0.55) while the social adjustment score (194.94±1.05) was lower than the non left behind group (202.82±0.79). The differences were statistically significant ( F =212.03, 16.52, 36.02, all P <0.01). Cross sectional network analysis showed that the "anticipated rejection likelihood" was the core node ( EI=-2.27 , BEI =-2.37), playing a key role in inter network connections and overall dynamic regulation. Longitudinal network comparison revealed statistically significant changes in the intensity centrality of the nodes "individual discrimination perception" and "anticipated rejection likelihood" (both P <0.05), while other nodes remained relatively stable. Cross lagged network analysis showed that the predictive effects of T1 on the variables at T2 were not statistically significant (maximum | r |=0.05, FDR corrected P >0.50), but the binomial test indicated a systematic positive correlation trend between the variables (66.7% positive correlation, P =0.04). Sensitivity analysis showed that the bridge effect of the "anticipated rejection likelihood" and "learning adjustment" nodes at T2 was more significant in the left behind group compared to the non left behind group. Conclusion The social adjustment issues of college students with left behind experiences require focused attention on the negative regulatory effect of "rejection cognition" and the positive regulatory effect of "learning adaptation".

Repetitive transcranial magnetic stimulation (rTMS) has become an essential method in psychiatric disorders. However, many problems occurred in clinical application. This article interpreted the Association Standard T/CMEAS 011-2023'Operating Specifications for Repetitive Transcranial Magnetic Stimulation in Clinical Applications on Psychiatric Disorders′ released by the Chinese Medicine Education Association. The main content included a range of applications, normative references, terms and definitions, site specifications, equipment specifications, ability specifications of rTMS operators and rTMS process specifications.This article provided suggestions for clinical applications of rTMS on psychiatric disorders.

Occupational contact dermatitis (OCD) is an occupational inflammatory skin disease. According to its pathogenesis, it can be divided into irritant contact dermatitis and allergic contact dermatitis. This review introduced the high-risk occupations of OCD, its incidence, common irritants and allergens, and corresponding treatments. Agriculture workers, construction workers, production workers, hairdressers, and medical workers are high-risk occupations of OCD who should be paid attention to.

Purpose/Significance To explore the characteristics and clinical significance of differentially expressed genes closely re-lated to HPV E6/E7 by using bioinformatics.Method/Process The cervical tissue and clinical information of cervical cancer in TCGA and GTEx of UCSC are used as the training set.The expression profile chip GSE63514 related to cervical cancer in GEO is used as the validation set.Firstly,the limma package of R software is used to screen DEGs of tumor and normal samples,and Venn map of genes re-lated to E6/E7 protein in MigDB is made.Survival analysis is performed by survival kit and verified by ROC and protein expression lev-els.Secondly,key genes are obtained by copy number variation and methylation correlation.Finally,the specific co-expression network is constructed and enrichment analysis and immune infiltration analysis are performed.Result/Conclusion There are 101 differentially expressed genes related to HPV E6/E7 protein,and three genes are found to have significance after screening,namely E2F1,MCM4 and PCNA.At the same time,it is found that the genes in the specific coexpression network are significantly enriched in the DNA replication and chromosome organization pathways.Immune correlation analysis shows that key genes are significantly associated with CD4 T cells,B cells and neutrophils.DNA replication,chromosome organization,etc.,are the molecular mechanisms and key genes significantly related to the development of cervical squamous cell carcinoma and HPV E6/E7 encoded proteins.

Objective: To explore the clinical effect of artificial dermis on partial nail bed defects. Methods: From May 2013 to September 2016, 16 cases of 21 fingers with partial nail bed defect and bone exposure received primary repair with artificial dermis after debridement. Then the outer dressing was changed 3 days after the operation, and the dressing was changed once every 3 to 5 days. The pink dermis like tissue was placed on the wound surface 2 to 3 weeks after the operation. The wound surface was naturally epithelialized. Results: All the fingers were survived after artificial dermis repair, and the fingertip surface of nail bed defect was epithelialized naturally and healed well. Postoperative follow-up was 5 to 16 months, with an average of 8.2 months. The growth of fingernails was smooth with symmetrical appearance, natural toughness, good adhesion between the nail body and the nail bed, and no pain or hyperesthesia at the tip. Results of curative effect evaluation showed excellent in 18 fingers, good in 3 fingers. Results of patient′s satisfaction with postoperative finger appearance showed very satisfactory in 13 cases and satisfactory in 3 cases. Conclusions The method of repairing partial defect of nail bed using artificial dermis is simple with minimal damage and a good clinical effect.
