Objective:To investigate the dynamic changes of plasma high-mobility group box 1 (HMGB1) and its correlation with functional outcome and symptomatic intracranial hemorrhage (sICH) after endovascular treatment (EVT) in patients with acute large vessel occlusion stroke (ALVOS).Methods:Patients with ALVOS admitted to the Department of Neurology, Zengcheng District, Nanfang Hospital, Southern Medical University from June 2021 to April 2023 were included retrospectively. Plasma HMGB1 before EVT and at 6, 24, and 48 hours after procedure was detected, and the dynamic changes of plasma HMGB1 were compared and analyzed. The primary endpoint was the functional outcome evaluated using the modified Rankin Scale at 90 days of onset. A score of 0-2 was defined as good outcome and >2 was defined as poor outcome. The secondary endpoint was sICH, which was defined as the occurrence of hemorrhagic infarction after EVT and an increase of ≥4 in the National Institutes of Health Stroke Scale (NIHSS) score from baseline. Multivariate logistic regression analysis was used to evaluate the predictive value of HMGB1 for poor outcome and sICH. Results:A total of 73 patients with ALVOS received EVT were included. There were 54 males (74.0%), aged 62±12 years. The median time from onset to door was 90 minutes (interquartile range, 40-180 minutes), and the median time from onset to femoral artery puncture was 181 minutes (interquartile range, 140-280 minutes). Twenty-nine patients (39.7%) underwent bridging intravenous thrombolysis (IVT). At 90 days after onset, 37 patients (50.7%) had poor outcome, and 12 (16.4%) died during follow-up. Eleven patients (15.1%) developed sICH. After EVT, plasma HMGB1 showed a temporal increase, reaching its peak at 48 hours (median, 102.57 μg/L). Subgroup analysis showed that HMGB1 in the bridging IVT group at 6 hours ( P<0.05) and 24 hours ( P<0.05) after procedure were significantly higher than that at baseline. The non-bridging IVT group showed a significant increase at 6 hours after procedure ( P<0.05). There was no statistically significant difference in HMGB1 between the bridging IVT group and the non-bridging IVT group at the same time point. Multivariate logistic regression analysis showed that after adjusting for age, ischemic heart disease, triglycerides, uric acid, baseline NIHSS score, and sICH, the third quartile (adjusted odds ratio 7.087, 95% confidence interval 1.243-40.419; P=0.027) and fourth quartile (adjusted odds ratio 7.544, 95% confidence interval 1.260-45.172; P=0.027) of plasma HMGB1 were independent risk factors for poor outcome at 6 hours after procedure. The postoperative plasma HMGB1 in the sICH group was significantly higher than that in the non-sICH group ( P<0.05), but multivariate analysis showed no independent correlation between plasma HMGB1 and sICH. Conclusion:The elevation of plasma HMGB1 in patients with ALVOS at 6 hours after EVT is independently associated with poor outcome at 90 days after onset, but not with sICH.

Objective To explore the influence of personality traits of nurses in intensive care unit (ICU) on death coping self-efficacy,therefore to improve the capability of ICU nurses to cope with death and improve the quality of palliative care for ICU patients. Methods A convenience sampling method was used to enrol ICU nurses as research subjects from 43 Grade ⅢA hospitals between July 2023 and February 2024. The study was conducted using the general data questionnaire,the Chinese big five personality inventory-brief version (CBF-PI-B),and the death coping self-efficacy scale (DCSS). Multiple linear regression was used to analyse the relationship between personality traits and death coping self-efficacy of the ICU nurses after controlling for demographic factors. Results A total of 301 ICU nurses had completed the surveys. It was found that the total score for personality traits of ICU nurses was 156.2±20.8. The five dimensions of personality traits,scored from high to low,were identified as conscientiousness,agreeableness,openness,extroversion and neuroticism. The total score for death coping self-efficacy was found at 98.5±18.2. The three dimensions of death coping self-efficacy scored from high to low were hospice care ability,death preparation ability and grief coping. The linear hierarchical regression model showed that the traits of conscientiousness and extroversion were positively correlated with the death coping self-efficacy (P<0.05) while a trait of neuroticism was negatively correlated with the death coping self-efficacy (P<0.001),after controlling for variables such as working experience,participation in palliative care education courses within a year,experience of accompanying family members through death within a year and attitudes towards death. Conclusion The death coping self-efficacy is at a medium level among the ICU nurses. Managers of medical institutions should pay attention to the personality traits of ICU nurses and provide them with strongly targeted and personalised training. Trainings focus on personal traits would improve the death coping self-efficacy of the ICU nurses.

OBJECTIVE To observe the effects of low-dose esketamine on analgesia and inflammatory factors after thoracoscopic surgery. METHODS Totally 120 patients who underwent thoracoscopic lobectomy in our hospital from October 2021 to March 2022 were selected and randomly divided into low-dose group （group A）， conventional-dose group （group B）， normal saline group （group C） by using the random number table method， with 40 patients in each group. All the patients were anesthetized with traditional general intravenous anesthesia， group A and B were anesthetized with low dose or normal dose （0.2 or 0.5 mg/kg） of Esketamine hydrochloride injection， and group C was given normal saline intravenously. The visual analog scale （VAS） score 0， 6， 24， 48 h after operation and the consumption of sufentanil 24 h after operation were compared among 3 groups. The levels of white blood cell count （WBC）， neutrophil percentage， C-reactive protein （CRP）， tumor necrosis factor-α （TNF-α）， interleukin-1 （IL-1） and IL-6 were compared 30 min before and 24 h after surgery. The Pittsburgh sleep quality index （PSQI） score and the Beck depression inventory （BDI） score were compared before operation and 0， 1， 2 d after operation， and the occurrence of adverse reaction was also recorded. RESULTS At 0， 6 and 24 h after operation， VAS scores and the consumption of sufentanil within 24 h after operation in group A and B were significantly lower than group C； VAS score 6 h after operation in group A was significantly lower than that in group B （P＜0.05）. The levels of WBC， neutrophil percentage， CRP， TNF-α， IL-1 and IL-6 in the 3 groups 24 h after surgery were significantly increased， compared with 30 min before surgery； the levels of above indexes in group A and B were significantly lower than those in group C （P＜0.05）. PSQI score and BDI score 0， 1 and 2 days after operation in group A and B were significantly lower than those in group C， while BDI score 0 day after operation in group A was significantly lower than that in group B （P＜0.05）. The total incidence of adverse reaction in group A， B and C were 5.0%， 10.0% and 17.5%， without statistical significance （P＞0.05）. CONCLUSIONS The low-dose esketamine has significant analgesic effect after thoracoscopic surgery， can reduce the levels of inflammatory factors after surgery and improve sleep quality and depression， with good safety.

End-stage renal disease is the final stage of chronic kidney disease, and research on palliative care for end-stage renal disease patients in China is still in its infancy. The research content of palliative care for end-stage renal disease at home and abroad mainly includes identification and management of symptoms, advance care planning, psychosocial and spiritual support, and ethical issues in dialysis decision-making. However, practical experience is still insufficient. By focusing on the overview, development status, patient needs, as well as implementation forms and models of palliative care for endstage renal disease patients, this paper summarized the research progress and application status of related research, with a view to providing references for future domestic research and clinical practice in this field.

Objective:To explore the value of nursing checklist in posterior surgery for thoracolumbar fracture with general anesthesia under prone position.Methods:A retrospective case series study was conducted to analyze the clinical data of 106 patients with thoracolumbar fracture admitted to Sir Run Run Shaw Hospital，Zhejiang University School of Medicine from June 2018 to May 2020. There were 80 males and 26 females，with age range of 25-57 years［（48.6 ± 11.9）years］. Segments of injury were located at T 11 in 18 patients，at T 12 in 26，at L 1 in 21，at L 2 in 25 and at L 3 in 16. All patients were treated with thoracolumbar posterior screw fixation under general anesthesia. Of all，51 patients received conventional postural nursing from June 2018 to May 2019（control group），and 55 patients received prone position nursing scheme for general anesthesia on the basis of conventional postural nursing from June 2019 to May 2020（verification group）. The incidence of postoperative complications including stress injury，brachial plexus injury，ulnar nerve injury and ocular discomfort as well as length of hospital stay and patients’ satisfaction were compared between the two groups. Visual analogue scale（VAS）and Oswestry disability index（ODI）were also used to measures outcome at postoperative 3 months. Results:All patients were followed up for 8-12 months［（10.5±0.9）months］. Verification group and control group showed significant differences in the incidence of stress injury（4%∶29%），brachial plexus injury（4%∶16%）and ocular discomfort consisiting of tears（2%∶12%），foreign body sensation（0%∶4%）and dryness（4%∶16%）（ P < 0.05），not in ulnar nerve injury and blurred vision. Length of hospitalization in verification group was（7.0±1.3）days，significantly shorter than that in control group［（9.9±1.9）days］（ P < 0.05）. Satisfaction of patients in verification group and control group was 85%（47/55）and 69%（35/51），respectively（ P < 0.05）. At 3 months postoperatively，VAS in verification group［（1.9 ± 0.8）points］was significantly lower than that in control group［（3.5±1.1）points］（ P < 0.05），and ODI was similar between the two groups（ P > 0.05）. Conclusions For patients with thoracolumbar fracture treated by posterior surgery with general anaesthesia under prone position，nursing checklist helps reduce occurrence of the related complication，shorten length of hospital stay，improve patient satisfaction，reduce postoperative pain and promote rehabilitation.

Objective:To explore the current situation of stigma and posttraumatic growth in female infertility patients, and to analyze the correlation between them.Methods:From January to May 2019, this study selected 110 female infertility patients of reproductive medicine center in a ClassⅢ Grade A hospital of Zhejiang Province as subjects by convenience sampling. Those infertility patients were investigated with the general information questionnaire, Infertility Stigma Scale (ISS) and the Post-traumatic Growth Inventory-Chinese version (PTGI-C) . A total of 110 questionnaire were sent out and 104 valid of them were collected.Results:Among 104 female infertility patients, the score of ISS was (67.14±14.33) with the intermediate level; the score of PTGI-C was (63.92±11.76) also with the intermediate level. There were statistical differences in the scores of post-traumatic growth among female infertility patients with different education levels, characteristics and whether being the only child ( P<0.05) . The scores of ISS of female infertility patients had statistically negative correlations with the total score and dimension scores of PTGI-C ( P<0.01) . Hierarchical regression analysis showed that the main influencing factors of posttraumatic growth in female infertility patients were the education levels, years of infertility, total score of stigma and scores of emotion and behavior with statistical differences ( P<0.05) . Conclusions:Stigma of female infertility patients is negatively correlated with the posttraumatic growth, which points that nurses could positively reduce the stigma of those patients so as to improve their posttraumatic growth.

To understand the survival stress of community-dwelling people with mental disorder. Fifteen cases were selected by purposive sampling and received semi-structured individualized interviews.The data were analyzed by Colaizzi framework and themes were extracted. Four themes were extracted:physiological stress due to psychiatric symptoms and side effects of drugs;psychological stress due to the outcome of mental illness and to conflict of roles in daily life;social and environmental stress such as social discrimination,lack of job opportunities,and difficulty in obtaining social welfare resources;and interpersonal stress caused by discrimination and deteriorating family relations. Community-dwelling people with mental illness have a higher level survival stress after returning to their families and society,with the stressors including symptoms of illness,social discrimination,and interpersonal relationship.Eliminating self-discrimination of the patients,improving social support and social welfare system,and increasing individualized community mental rehabilitation activities may reduce the survival stress of these patients and promote their rehabilitation.

OBJECTIVE: Poly (ADP-ribose) polymerase (PARP) is an important molecule in the early stress response of DNA damage, which is involved in DNA damage repair and cellular senescence. Olaparib, as PARP inhibitor, has an anti-tumor effect on high grade serous ovarian cancer, but its effects on cellular senescence have not been reported. This study intends to explore the role of olaparib in the regulation of senescence in ovarian cancer cells. METHODS: The effects of olaparib on the senescence of ovarian cancer cells were detected by using the senescence-associated β-galactosidase (SA-β-Gal) and senescence-associated heterochromatin aggregation (SAHF). Quantitative real-time polymerase chain reaction was used to analyze the senescence-associated secretory phenotype (SASP). Cell cycle and apoptosis were detected by flow cytometry. The effect of olaparib on tumor growth was analyzed in a nude mouse xenograft transplantation model. RESULTS: Long-term (6 days) treatment with olaparib (5 μM) significantly inhibited the growth of ovarian cancer cells, leading to arrest the cell cycle at G0/G1 phase, significant increase the number of positive SA-β-Gal stained cells and positive SAHF cells. The expression of P16 and retinoblastoma protein (p-RB) were significantly enhanced in SKOV3 cells under olaparib treated, meanwhile, the expression of P53 and p-RB were upregulated in A2780 cells. In OVCAR-3 cells, the expression of P53 was downregulated and p-RB was upregulated. Mice with SKOV3 xenograft transplantation was given olaparib (10 mg/kg/day) via abdominal cavity administration, the tumor volume was reduced (p < 0.01). CONCLUSION: Continuous low dosage administration of olaparib induced senescence under P16 or P53 dependent manner in ovarian cancer.
