Objective To assess the clinical efficacy of butylphthalide sequential therapy(BST)as an adjuvant therapy for delayed onset encephalopathy caused by acute carbon monoxide poisoning(DEACMP).Methods DEACMP patients who visited the department of neurology at Yan'an People's Hospital from January 2018 to June 2023 were selected as the research subjects.Using a random number table method,DEACMP patients were randomly divided into hyperbaric oxygen therapy(HBOT)group,glucocorticoid(GC)group(GC combined with,HBOT),and BST group(HBOT,GC combined with BST),all of which were treated continuously for 30 days.The incidence of adverse reactions and clinical efficacy during the treatment among three groups of DEACMP were observed and compared.Inflammation indicators,neurological damage indicators,cognitive function,neurological function,and daily living ability before and after treatment among three groups were compared.Results A total of 120 patients were included in the study,with 40 patients in each group.During the treatment period,no serious adverse reactions were observed in any of the three groups of patients,and no patient terminated treatment due to adverse reactions.The total effective rate of BST group was significantly higher than those of GC group and HBOT group,while the total effective rate of GC group was higher than that of HBOT group(P<0.05).Before treatment,there was no statistically significant difference(P>0.05)in the scores of inflammation indicators,neurological damage indicators,cognitive function,neurological function,and daily living function among the three groups.After treatment,the serum LP-PLA2,SIRI,TNF-α,S100-β,and the NSE levels decreased compared to before treatment(P<0.05),and the indicators of the BST group was lower than those of the HBOT group and GC group,while the indicators of the GC group was lower than those of the HBOT group(P<0.05).After treatment,the MMSE,MoCA,and BI scores of the three groups increased compared to before treatment(P<0.05),but the NIHSS score decreased(P<0.05).In addition,the MMSE,MoCA,and BI scores of the BST group were higher than those of the HBOT and GC groups(P<0.05),while the NIHSS scores were lower than those of the HBOT and GC groups(P<0.05).The MMSE,MoCA,and BI scores in the GC group were higher than those in the HBOT group,while the NIHSS scores were lower than those in the HBOT group(P<0.05).Conclusion Compared with HBOT treatment and HBOT combined with GC treatment,BST adjuvant therapy can improve the clinical efficacy,inflammatory status,cognitive function,and daily living ability of DECAMP patients.

OBJECTIVETo investigate the effect of functional blocking of endogenous miR-23a with a specific antisense oligonucleotide (ASO) on the proliferation and invasiveness of gastric adenocarcinoma cell line MGC803 in vitro.

METHODSA specific ASO targeting miR-23a, namely ASO-23a, was transfected into MGC803 cells to block endogenous miR-23a. The mRNA level of miR-23a in the transfected cells was detected with quantitative real-time PCR. The changes of cell proliferation following the transfection were detected with MTT assay and colony formation assay, and TUNEL assay and Transwell assay were employed to evaluate the changes in cell apoptosis and invasiveness, respectively.

RESULTSQuantitative real-time PCR demonstrated efficient functional blocking of endogenous miR-23a in MGC803 cells by ASO-23a. Suppression of miR-23a with ASO-23a obviously inhibited cell growth, colony formation and invasiveness of MGC803 cells and significantly enhanced the cell apoptosis.

CONCLUSIONASO-23a can efficiently block the function of endogenous miR-23a in MGC803 cells to inhibit cell proliferation and invasion and promote cell apoptosis.

Objective:To evaluate the effect of self-made lithotomy heating mask on intraoperative and postoperative body temperature and short-term postoperative outcome indicators in patients undergoing radical resection of rectal cancer.Methods:Using the method of quasi experimental research design, 100 patients with open rectal cancer in Ningbo Huamei Hospital of the University of Chinese Academy of Sciences from February to July 2021 were selected as the research objects. The patients were divided into experimental group and control group with 50 cases in each group. The control group was kept warm by routine methods, and the experimental group was kept warm by self-made lithotomy heating hood. The changes of core temperature at different time points before, during and after operation were compared between the two groups. The incidence of accidental hypothermia and shivering, the recovery time of anesthesia, and the incidence of various complications within 48 hours after operation were compared between the two groups after operation from the beginning of the operation to 6 hours after returning to the ward.Results:From 30 minutes after anesthesia to 3 hours after entering the ward, the core temperatures of the experimental group at 10 time points were higher than that of the control group, and the differences were statistically significant ( t values were 3.48-37.30, all P<0.01). From the beginning of surgery to 6 h after returning to the ward, the incidence of perioperative accidental hypothermia in the experimental group was 2% (1/50), lower than 24% (12/50) in the control group, and the difference was statistically significant ( χ2=11.06, P<0.05) . The number of cases of shivering in the experimental group was 10, lower than that in the control group of 22, the difference was statistically significant ( χ2=6.62, P<0.05) . The recovery time, extubation time and stay time in anesthesia recovery room of the experimental group were (8.44 ± 2.83), (13.05 ± 4.72), (74.51 ± 11.82) min, which were shorter than those of the control group (15.35 ± 2.09), (17.62 ± 3.28), (89.14 ± 9.19) min, and the difference was statistically significant ( t=-13.89, -5.62, -6.91, all P<0.01). The number of cases of agitation, delirium and nausea and vomiting in the experimental group was 3, 1 and 2 respectively, which was lower than 13, 7 and 8 in the control group, and the difference were statistically significant ( χ2=7.44, 4.89, 4.00, all P<0.05). There was no significant difference in the incidence of adverse cardiac events between the two groups ( P>0.05). Conclusions:The application of self-made lithotomy heating mask in open rectal cancer surgery can effectively improve the risk of hypothermia at different time points during and after surgery, reduce the incidence of shivering, restlessness, postoperative nausea, vomiting and delirium, shorten the time of awakening and extubation, and prevent postoperative complications. It has practical value in clinic.

Objective To explore how the emotional experience and stress symptoms associated with compassion fatigue emerges,develops and subsides,as well as their coping strategy for compassion fatigue. Methods By purposive sampling integrating with snowball sampling method,semi-structured reviews with open-ended questions were conducted among 47 registered nurses who are working or have ever being in clinical frontline department to gain their in-depth views about compassion fatigue. Theme analysis was used to analyze the data.Results In emotional experience,two main themes were extracted:positive and negative emotion. Six subthemes including happy,high spirits,interests,sense of self-value,sense of achievement and occupational pride were extracted from positive emotion. While nine subthemes including compassion,grief,depressed mood,irritability,guilty,powerlessness,apathy,fear and anxiety were extracted from the negative emotion. Conclusions Clinical nurses are lack of basic knowledge about compassion fatigue,and their work and life are influenced by compassion fatigue. It should be emphasized and enhanced that domestic hospital administrators should identify and take precaution against compassion fatigue.

Objective To investigate the current status and influencing factors of compassion fatigue in clinical nurses,and to provide theoretical references for prevention of nurse burnout and promotion of nurse retention.Methods Totally 992 clinical nurses from ten tertiary hospitals were enrolled through random cluster sampling to complete general information questionnaire,the Professional Quality of Life Scale (Pro-QOL-V),the Resilience Scale for Adults(RSA) and the Jefferson Scale of Empathy·Health Professionals(JSE-HP).Results The prevalence of moderate and high risk of secondary stress and burnout were 71.1％,73.2％,respectively;clinical nurses with work experience of 6 to 10 years presented the highest level of burnout(P＜0.01);lower empathy and resilience,as well as adverse work environment were risk factors of compassion fatigue.Multiple regression analysis showed that the influencing factors of nurse burnout were compassion satisfaction,secondary stress,resilience,workload,recognition,empathy,and payment,which explained 70.5％ of the total variance.Conclusion Secondary stress,burnout and compassion satisfaction in clinical nurses are influenced by nurses' empathy,resilience and work environment,and nursing administrators should pay attention to receiving recognition as positive predictors of burnout,except for workload and payment.
