T-cell exhaustion is characterized by the stepwise and progressive loss of T cell functions under conditions of antigen-persistence, which occurs following chronic infections and tumor outgrowth. Exhausted T cells present functional defects, express multiple inhibitory receptors and show reprogrammed transcriptional regulation. As T cell exhaustion is correlated to its dysfunction to control infections and tumors, exploring new strategies to target exhausted T cell may reverse this dysfunctional state and reinvigorate immune response. This study takes CD8+ T cell as an example, which acts as an important subset involved in exhaustion state, discuss current understanding of the properties of exhausted T cell and the mechanisms that promote and maintain this state, and reveal new therapeutic targets for chronic infection and cancer.

Objective To study the renal damage of patients with juvenile primary Sjgren's syndrome (pSS)and its clinical manifestations,pathologic characteristics with biopsy,treatment and prognosis.Methods Ten patients with juvenile pSS complicated with renal impairments were retrospectively analyzed.Data of these 10 patients were compared with those without renal impairments.Results Ten patients complicated with renal impairments in 24 patients with juvenile pSS,9 of them presented with type I renal tubular acidosis(RTA), 5 with hypokalemia paralysis,3 with calcification of the renal tissue,3 with positive urine protein.1 with dia- betes insipidus.There was no significant difference between patients with renal impairments and those without. Three patients underwent kidney biopsy that showed chronic interstitial nephritis(CIN)with extensive lymp- hoplasmie cell infiltration.Two patients had glomerular lesions and one of them was diagnosed as pSS over- laped with systemic lupus erythematosus(SLE).Steroid and immunosuppressive agents had significantly alle- viated symptoms and the hypergammaglobulinemia was significantly improved.Conclusion Renal impairment may be the major complication in juvenile pSS.The major clinical manifestations are RTA and the glomeruli are involved occasionally.Treatment with steroid anti immunnsuppressive agents should be given to those who have evidence of systemic involvement.

OBJECTIVE: The optimal multiplicity of infection (MOI) of the recombinant adenovirus Ad-Rad50-GFP carrying a mutant Rad50 gene expression region on the cell growth of nasopharyngeal carcinoma and the viral amplification efficiency of CNE1 cell infected by this adenovirus were studied. METHOD: The biological titer of Ad-Rad50-GFP was measured by end point dilution method. The impact of recombinant adenoviral vector transfection on the growth of CNE1 cells was observed by cell growth curve. Transfection efficacy of recombinant adenoviral vector was observed and calculated through fluorescence microscope. The expression f mutant Rad50 in the Ad-Rad50-GFP transfected CNE1 cells with optimal MOI was detected by Western Blot after transfection. RESULT: The biological titer of Ad-Rad50-GFP was 1.26 x 10¹¹ pfu/ml. CNE1 cell growth was not influenced significantly as they were transfected by recombinant adenoviral vector with MOI less than 50. Transfection efficacy of recombinant adenoviral vector was most salient at 24 hours after transfection, with the high expression of mutant Rad50, and the efficiency still remained about 70% after 72 hours. CONCLUSION Recombinant adenoviral vector Ad-Rad50-GFP could transfect CNE1 cells as well as result in the expression of mutant Rad50 in CNE1 cells effectively. MOI = 50 was the optimal multiplicity of infection of CNE1 cells transfected by recombinant adenoviral vector Ad-Rad50-GFP.

Objective:To establish a fast method for the generation of immature dendritic cells(DCs) from human peripheral blood mononuclear cells(hPBMCs) in vitro.Methods: High purity human CD14+ monocytes were collected using density Ficoll gradient centrifugation and MACS beads sorting system.iDCs(Immature DC) were induced after cultured with rhGM-CSF and rhIL-4 on the fourth day.Fluorescence activated cell sorting(FACS) was used to identify cell surface markers(CCR5) and capabilities of antigen uptake of iDCs on the fourth day.Ordinary optical microscope,scanning electron microscopy and transmission electron microscopy were used to observe surface and internal structure of iDCs on the fourth day of culture conditions.Results: FACS result shows that the purity of CD14+ monocytes collected from hPBMCs were more than 94%.The antigen uptake capability and CD195 of iDCs was detected on the fourth day of cultured conditions.Typical surface and internal structure characteristics of iDCs were observed.Conclusion: Rapid induction culture is an effective method for obtaining a large number of iDC with typical characteristics in vitro,and can be used for further experimental study.

Background Job burnout and depressive symptoms are prevalent among occupational populations, with a close relationship between them. Sleep quality, as a potential mediating factor, significantly affects the mental health of workers. Objective To explore the relationship between job burnout, sleep quality, and depressive symptoms, and determine whether sleep quality mediates the relationship between job burnout and depressive symptoms. Methods From April 25 to May 1, 2024, this study employed cluster sampling to conduct a questionnaire survey among individuals engaged in various occupations across five cities in the Ningxia Hui Autonomous Region. The questionnaires included socio-demographic information, as well as the Chinese Maslach Burnout Inventory (CMBI), the Pittsburgh Sleep Quality Index (PSQI), and the Patient Health Questionnaire-9 (PHQ-9) for assessing burnout, sleep quality, and depressive symptoms, respectively. Out of the 4106 questionnaires distributed, a total of 3837 questionnaires were valid, and the valid recovery rate was 93.45%. The distribution among demographic variables in burnout, sleep quality and depressive symptoms were statistically analyzed. A binary logistic regression model was used for multifactor correlation analysis; Pearson correlation was used to test the correlation between burnout, sleep quality, and depressed mood. Modelling and mediated effect path mapping were performed using Amos 24.0 software. Results The postive rate of occupational burnout in the workers was 97.49% (3741/3837), the positive rate of poor sleep quality was 66.77% (2526/3837), and the positive rate of depressive symptoms was 75.68% (2904/3837). There were statistically significant differences in depressive symptoms by ages, shift types, working years, marital status, smoking habits, drinking habits, and exercising frequency (P < 0.05). The logistic model indicated that working years, drinking habits, job burnout, and overall sleep quality were significant factors influencing the occurrence of depressive symptoms (P < 0.05). The correlation analysis revealed positive correlations between depressive symptom scores and job burnout scores (r=0.045, P < 0.01), between depressive symptom scores and sleep quality scores (r=0.480, P < 0.01), and between job burnout scores and sleep quality scores (r=0.054, P < 0.01). Furthermore, the indirect effect of job burnout on depressive symptoms through sleep quality was 0.100 (95%CI: 0.204, 0.252; P < 0.01). Conclusion Job burnout and sleep quality are significant factors associated with the occurrence of depressive symptoms among occupational populations, and sleep quality plays a partial mediating role in depressive symptoms associated with job burnout. This finding may provide a scientific basis for developing intervention strategies to control depressive symptoms among workers.
