Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective To explore the influencing factors of job satisfaction, social support and dimission intention of nursing staff. Methods Chose 295 cases of medical staff randomly in 2 provincial hospitals in Dalian. Collected data with self-designed questionnaire and analyze influencing factors. Results The influencing factors of job satisfaction included culture level, marriage status, working age, ideal commitment and emotional exhaustion; The influencing factors of social support included culture level, children, individual sense of achievement, standared commitment, economy commitment, society commitment and emotional estrangement;The influencing factors of dimission intention were ideal commitment, night-watch, emotional exhaustion and sentiment estrangement. Conclusions The influencing factors of job satisfaction, social support and dimission intention were defined, we should comprehensively improve physical and mental health of nursing staff aimed at these factors.

OBJECTIVETo investigate the changes in the systemic inflammatory response and T cell induced immunity after systemic administration of recombinant human growth hormone (rhGH) during early postburn stage.

METHODSForty Sprague-Dawley (SD) rats were randomly divided into three groups for the study. The rats in control group (C, n = 6) were only used for the determination of plasma levels of the cytokines, such as TNFalpha, IL-2, IL-6 and CD4(+) and CD8(+) cells. The SD rats in burn with rhGH treatment group (BT, n = 18) and burn without treatment group (B, n = 18) were inflicted with III degree scalding injury on the back. rhGH was injected subcutaneously on the abdomen of the rats in a dose of 6 IU/kg for 10 days in BT group. The blood samples were harvested from the rats in the two groups for the evaluation of the above indices.

RESULTSThe plasma levels of TNFalpha, IL-2, IL-6 and CD4(+) and CD8(+) cells were increased on the 3(rd) postburn day (PBD) and decreased on the 6(th) PBD in B group, while the CD4(+) and CD8(+) cells were increased significantly and the plasma levels of TNFalpha, IL-2, IL-6 decreased obviously on the 3(rd) PBD in BT group. And the plasma levels of IL-2 and IL-6 in BT group on the 6(th) PBD showed no difference from those in C group. But the plasma TNFalpha level in BT group was evidently higher than that in B and C group on the 6(th) PBD. Furthermore, the plasma levels of TNFalpha, IL-2 and IL-6 in BT group were still increased gradually on the 10(th) PBD, while the IL-2 and IL-6 levels were decreased obviously in B group, but the TNFalpha level was increased.

CONCLUSIONSystemic administration of rhGH during different states of stress exerted different effects on T cell induced immunity and systemic inflammatory response.
