Objective To explore the correlations of perceived social support and burnout with general well-being among caregivers in nursing homes. Methods One hundred nursing workers were selected from three nursing homes in Guangzhou. Perceived social support scale ( PSSS ) , Maslach burnout inventory ( MBI ) and general well-being schedule ( GWBS ) were used to investigate the status of their support, burnout and general well-being and analyze the correlations between them. Results The scores on perceived social support, job burnout and general well-being were (59.00 ± 9.00), (2.49 ± 0.88), (77.19 ±9 .90), respectively, all at moderate level. The scores on emotional exhaustion and depersonalization were significantly higher than the norms (both P<0.001). Job burnout together with its three dimensions was negatively correlated with general well-being (all P<0.01), while perceived social support was positively correlated with general well-being ( P < 0 . 01 ) . The exogenous family support , emotional exhaustion and personal accomplishment influenced caregiver′s general well-being (all P<0.01). Conclusions Perceived social support, job burnout and general well-being are all at moderate level in caregivers of nursing homes. The higher the perceived social support, the lower the job burnout, the higher the passion and the general well-being in care workers. The general well-being of caregivers of the nursing homes was not high. The managers should pay more attention to them and measures should be taken to promote their physical and mental health.

Objective To evaluate the security of inspiring high concentration oxygen by detecting the reactive oxygen species of the rats brain homogenates after inspiring high concentration oxygen for a certain time.Methods Sixty wister rats weighting 150~200g were randomly devided into five groups(the group of 4h、8h、12h、16h and the control group,12/group).The experimental rats were exposed to 85%~100% oxygen in a self-made chamber and the control animals were kept in normal room air.The Concentration of the MDA,SOD,GSH,NO,NOS,CAT and T-AOC of the brain homogenates was detected.Results Compared with the control group,the level of MDA,NO and NOS in the brain homogenates grew up markedly(P

Objective To explore the impact of macrophage-to-myofibroblast transition(MMT)on pulmonary fibro-sis induced by acute lung injury by LPS.Methods Totally 21 male mice were randomly classified into 7 groups:control group,model group(LPS-PF)at different time points and intervention group of clodronate-liposomes(CL-LIP)treatement at different time points(n=3).Pulmonary fibrosis was identified by HE and Masson staining microscopy.The immuno-fluorescence technology was used for the evaluation of numbers of macrophage-to-myofi-broblast transition cells(MMT cell which co-expressed CD68 and α-SMA).Bone marrow-derived macrophages(BMDMs)were randomly classified into two group:control(Ctrl)group and TGF-β1-treated group induced by transforming growthfactor-β1.α-SMA,FN and Col1 were detected by RT-qPCR.The expression of α-SMA,Smad3 and p-Smad3 protein was evaluated by Western blot.Results At day 7,the Ashcroft score of lung tissue in LPS-PF mouse model was significantly increased when compared with the Ctrl group(P＜0.01);While the score signifi-cantly declined when the model was pretreated with CL-LIP(P＜0.05).As detected by immuno-fluorescence stai-ning,in CL-LIP group the number of CD68-positive cells co-labeled with α-SMA was obviously less then that of LPS-PF group of the corresponding time point(P＜0.01).When the BMDMs were stimulated by TGF-β1 at 24 h,48 h and 96 h respectively,a higher expression of α-SMA,FN,Col1,were found in TGF-β1-treated group than that in Ctrl group at the corresponding time point(P＜0.01).The expression of Smad3,p-Smad3 significantly higher in LPS-PF group(at both day 7 and day 10)and TGF-β1-treated group(at both 48 h and 96 h)as compared to cor-responding control group(P＜0.01).Conclusions MMT promotes pulmonary fibrosis induced by ALI via LPS.Smad3 is proved to be involved in the MMT process.

Objective To review the research of self-management intervention in patients with hematopoietic stem cell transplantation,clarify the intervention elements,so as to provide references for clinical practice and future related research.Methods According to the scoping review framework,a literature search was performed in the PubMed,Embase,CINAHL,Web of Science,Cochrane Library,CNKI,Wan fang Database,VIP,CBMdisc for all the studies on self-management intervention of patients with hematopoietic stem cell transplantation.The retrieval time was from the establishment of the database to December,2022.There were 2 researchers who extracted and analyzed the data of the included literature.Results A total of 12 articles were included,including 3 randomized controlled trials,8 quasi-experimental studies,and 1 mixed study.6 studies were conducted with interventions based on the theoretical basis or nursing model such as self-management oriented 5A nursing model,continuous nursing model,problem-based learning theory.The intervention methods of 12 studies included nurse-led self-management guidance,mobile applications,multidisciplinary collaboration,and graphic cards.The intervention time was mostly 1～3 months.The outcome indicators included feasibility evaluation indicators such as operability,ease of use,and user satisfaction of the application,and effect evaluation indicators such as self-management ability,quality of life,and medication compliance of patients.The results showed that self-management interventions could improve patient self-management ability,quality of life,medication compliance,and improve their psychological and nutritional status.Conclusion The research on self-management intervention in patients with hematopoietic stem cell transplantation is still in the development stage,and its positive effect has been preliminarily verified.Medical staff should strengthen the self-management evaluation of patients with hematopoietic stem cell transplantation,play the role of multidisciplinary team,use electronic health intervention methods,and formulate multi-level,scientific and effective self-management intervention programs.

Objective:To access the clinical efficacy and safety of hydroxychloroquine (HCQ) in treatment of IgA nephropathy (IgAN).Methods:The data of IgAN patients who were diagnosed by renal biopsy in the First Affiliated Hospital, College of Medicine, Zhejiang University from May 2016 to August 2020 and had been treated with HCQ for more than 6 months without other immunosuppressants were retrospectively analyzed. The efficacy and side effects were compared between groups according to the baseline urine protein/creatinine ratio (UPCR) or whether combined with renin-angiotensin-aldosterone system inhibitor (RAASi).Results:A total of 121 patients were enrolled, including 45 males (37.19%). At baseline, the median UPCR was 0.69(0.45, 1.00) g/g; the median estimated glomerular filtration rate (eGFR) was 93.46(73.14, 115.67) ml·min -1·(1.73 m 2) -1; the median serum creatinine was 80.00(61.00, 98.00) μmol/L, and the serum albumin was (44.39±3.36) g/L. After HCQ treatment, UPCR and red blood cells were significantly decreased compared with baseline (all P<0.05). Triglyceride, total cholesterol and low-density lipoprotein cholesterol were also significantly decreased during the follow-up period. Serum creatinine, eGFR, serum albumin and serum uric acid remained stable. After 6 months of follow-up, the total remission rate was 56.88%, including 15.60% of partial remission and 41.28% of complete remission; at the end of follow-up, the median follow-up time was 280.00(214.00, 411.00) days and the total remission rate was 56.20%, including 9.92% of partial remission and 46.28% of complete remission. Group analysis showed that the remission rate was 60.53% ( n=76) and 48.48% ( n=33) at 6 months (Mann-Whitney U test, Z=-2.331, P=0.020) and 57.65% ( n=85) and 52.78% ( n=36) at the end of follow-up (Mann-Whitney U test, Z=-1.673, P=0.094) between patients with baseline UPCR<1 g/g and patients with baseline UPCR≥1 g/g; and the remission rate was 66.67% ( n=30) and 53.16% ( n=79) at 6 months (Mann-Whitney U test, Z=1.062, P=0.288) and 61.29% ( n=31) and 54.44% ( n=90) at the end of follow-up (Mann-Whitney U test, Z=0.930, P=0.352) between patients with single HCQ and patients with HCQ+RAASi. For side effects, the eGFR of 2 patients decreased by more than 30% compared with baseline, 1 patient relapsed and 1 patient developed blurred vision. Conclusions:HCQ is safe and effective for the treatment of IgAN.
