Objective To investigate the influence of individual psychological intervention on quality of life of HIV infection / AIDS patients.Methods 50 cases diagnosed as HIV infection / AIDS were selected,randomly divided into the control group and the observation group with 25 cases in each group.The control group received routine treatment and care,while for the observation group,the psychological health and quality of life were measured with SCL-90,SF-36 scales,then personalized psychological intervention was implemented after analyzing the influencing factors.Three months after discharge,the assessment test was carried out using SCL-90 and SF-36 scales,then compared the quality of mental health and life situation of the two groups.Results Mental health and quality of life between the observation group and the control group before intervention was not statistically significant.After intervention,the comparison is statistically significant Conclusions Individualized psychological intervention can improve patients quality of life.

Objective:To explore the protective effect of astaxanthin on acute liver injury induced by α-amanitin in mice.Methods:In June 2023, 42 healthy SPF male Kunming mice were selected. The mice were divided into blank control group, model (0.45 mg/kg α-amanitin) group, olive oil (10 ml/kg olive oil) group, low dose (20 mg/kg) astaxanthin group, medium dose (40 mg/kg) astaxanthin group, high dose (80 mg/kg) astaxanthin group and silybin (20 mg/kg) group by random number table method. Each group had 6 animals. Mice in the blank control group were intraperitoneally injected with 10 ml/kg normal saline, and mice in the other group were injected with α-amanitin. After that, the blank control group and model group were infused with 10 ml/kg normal saline, olive oil group and astaxanthin groups were given olive oil and astaxanthin according to dose by gavage, and silybin group was injected with silybin by dose. The drug was administered once every 12 h for a total of 4 doses. After 60 h, the mice were killed, the liver weight was weighed, and the liver index was calculated. The contents of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in serum of mice were detected, and the contents of superoxide dismutase (SOD), reduced glutathione (GSH), catalase (CAT), malondialdehyde (MDA) in liver tissues were also detected. One-way analysis of variance (ANOVA) was used to compare the difference of indexes among each group, and pairwise comparison was performed by Dunnett- t test. Results:The mice in the blank control group had smooth hair color, good spirit and normal behavior, while the mice in the other groups showed varying degrees of retardation and decreased diet, and no death occurred in each group. Body mass[ (26.67±1.51) g] and liver mass[ (1.23±0.14) g] in model group were significantly lower than those in blank control group [ (33.50±2.43) g and (1.87±0.16) g], and the differences were statistically significant ( P<0.05). The liver index [ (5.39±0.32) %, (5.83±0.30) %, (5.75±0.24) % and (5.78±0.16) %] in low, medium and high dose astaxanthin groups and silybin group were significantly higher than those in model group [ (4.61±0.12) %], and the differences were statistically significant ( P<0.05). Serum ALT and AST contents in model group [ (153.04±13.96) U/L and (59.08±4.03) U/L] were significantly higher than those in blank control group [ (13.77±1.29) U/L and (10.21±0.35) U/L], and the differences were statistically significant ( P<0.05). The contents of CAT, GSH and SOD in liver tissues of model group [ (9.40±2.23) U/mgprot, (3.09±0.26) μmol/gprot and (48.94±3.13) U/mgprot] were significantly lower than those of blank control group [ (26.36±2.92) U/mgprot, (6.76±0.71) μmol/gprot and (89.89±4.17) U/mgprot], the differences were statistically significant ( P<0.05). MDA content[ (6.33±0.24) nmol/mgprot] in liver tissue of model group was significantly higher than that of blank control group [ (0.91±0.21) nmol/mgprot], and the difference was statistically significant ( P<0.05). The CAT contents[ (18.64±1.76) U/mgprot, (18.20±1.76) U/mgprot, and (15.54±1.36) U/mgprot] in liver tissues of low, medium and high dose astaxanthin groups were significantly higher than those of model group, with statistical significances ( P<0.05). Compared with model group, SOD contents[ (72.16±7.44) U/mgprot, (93.18±5.28) U/mgprot, (103.78±7.07) U/mgprot, and (96.60±7.02) U/mgprot] in liver tissues of mice in low, medium and high dose astaxanthin groups and silybin group were significantly increased ( P<0.05), MDA contents [ (4.30±0.84) U/mgprot, (3.66±0.28) U/mgprot, (2.96±0.29) U/mgprot, and (2.88±0.39) U/mgprot] were significantly decreased ( P<0.05). Compared with model group, GSH content [ (7.90±1.25) μmol/gprot] in high dose astaxanthin group was significantly increased ( P<0.05) . Conclusion:Astaxanthin may alleviate acute liver injury induced by α-amanitin by alleviating oxidative stress in mice liver.

" Day surgery hospital-community joint follow-up model " results newly from the deepening implementation of the hierarchical medical system policy. It is designed to follow up the patients discharged from hospital but not fully recovered in time to ensure the prevention of adverse events after surgery. It can also improve the quality and efficiency of follow-up, and ensure the safety and integrity of the whole day operation management. In this context, through a comparative study of 720 patients discharged from daytime surgery in the region, patients in the combined follow-up group were followed up by telephone on the 3rd day after the operation by nurses from the day surgery ward. On the 10th and 20th days after the operation, the family doctor from the community health service center will visit the patient at home and follow up the patient by telephone. One month later, the patient returned to the hospital for follow-up consultation. Follow-up results show day surgery hospital-community joint mode as a helpful aid in keeping track of the patients postoperative rehabilitation, reducing complications and handling in time, while improving the ambulatory surgery perioperative safety.

Objective:To understand the potential categories of self-efficacy in stress injury management of nurses in operating room and analyze the characteristics of different categories of nurses.Methods:A cross-sectional survey was conducted from June to August 2022. A total of 469 operating room nurses from 12 Grade A hospitals in Guangxi, Sichuan, Guizhou, Yunnan, Shanxi, Xinjiang and Chongqing were selected by convenient sampling method as subjects. General data questionnaire, proactive personality Inventory, Caring behavior Inventory, transformational leadership inventory, nursing clinical Decision scale and nurses stress injury management self-efficacy scale were used to investigate. Potential profile was used to analyze nurses' self-efficacy in stress injury management, and multiple Logistic regression was used to analyze different potential factors.Results:The self-efficacy of nurses in the management of stress injury in operating room could be divided into three potential profiles: poor self-efficacy group (23.9%, 112/469), medium self-efficacy group (33.0%, 155/469) and good self-efficacy group (43.1%, 202/469). Proactive personality, caring behavior, transformational leadership, nursing clinical decision-making and educational background were the factors influencing self-efficacy of operating room nurses in stress injury management (all P<0.05). Conclusions:There are three potential profiles of self-efficacy in the management of stress injury in operating room nurses. Nursing managers can give targeted intervention strategies according to different characteristics of nurses to improve their self-efficacy.
