Objective To investigate the status quo and the relationship between emotional intelligence and resilience of emergency and ICU nurses in tertiary general hospitals in Chengdu. Methods A total of 660 emergency and ICU nurses were surveyed by a pack of questionnaires including the General Information Questionnaire, the Resilience Scale and the Wong and Law Emotional Intelligence Scale. Results The average total score of the resilience scale was 123.07 ±23.76 and the average item score of the resilience scale was 4.92±0.95. The average total score of the emotional intelligence scale was 58.69±8.74 and the average item score of the emotional intelligence scale was 3.67±0.55. The correlation coefficient between the emotional intelligence and the resilience was 0.62 (P<0.01). Three subdimensions of the emotional intelligence including the usage of emotion, the appraisal of self-emotion, the regulation of emotion and the positions of nurses accounted for 43.3%of the variances of the resilience. Conclusions Emotional intelligence played an important role in affecting the psychological resilience of emergency and ICU nurses in tertiary general hospitals in Chengdu, it could positively predict the resilience of nurses.

Objective:
To investigate the second-hand smoke behavior at home among smokers, so as to provide the reference for developing home tobacco control strategies.
Methods:
Permanent residents who were smokers and at the ages of 15 years and above were sampled from 10 streets (townships) in Xuhui District, Shanghai Municipality using the multi-stage random sampling and population-size proportional sampling methods in 2022. Demographic information, smoking status, awareness of second-hand smoke hazards and second-hand smoke behavior at home were collected by questionnaire surveys. Factors affecting second-hand smoke behavior at home were identified using a multivariable logistic regression model.
Results:
A total of 1 024 smokers were surveyed, including 769 males (75.10%) and 255 females (24.90%). The awareness of hazards of second-hand smoke was 33.59%; the awareness rate of second-hand smoke causing lung cancer in adults was the highest at 76.76%, while the awareness rate of second-hand smoke leading to premature birth and low birth weight in newborns was the lowest at 39.45%. There were 459 smokers with second-hand smoke behavior at home, accounting for 44.82%. Multivariable logistic regression analysis showed that occupation (the retired, OR=2.320, 95%CI: 1.276-4.218), frequency of smoking (often, OR=5.722, 95%CI: 3.977-8.231), smoking duration (a year and above, OR=10.089, 95%CI: 5.508-18.480), electronic cigarette use (occasionally, OR=2.994, 95%CI: 1.283-6.986), living with pregnant women or infants (no, OR=2.171, 95%CI: 1.367-3.448), family indoor smoking restrictions (no restriction, OR=13.926, 95%CI: 7.538-25.727) and awareness of second-hand smoke hazards (unknown, OR=1.562, 95%CI: 1.067-2.287) were the influencing factors for second-hand smoke behavior at home.
Conclusion
There were 44.82% smokers in Xuhui District with second-hand smoke behavior at home, which was influenced by occupation, living situation, smoking status, family indoor smoking restriction and awareness of second-hand smoke hazards.

Objective To investigate the effect of neuropeptide Y (NPY) on the osteoblastic differentiation of murine MC3T3-E1 cells and its mechanism related to the Wnt signaling pathway.Methods The murine MC3T3-E1 cells were divided into 4 groups according to the stimulators added:phosphate buffered saline (PBS) (control) and different concentrations of NPY (10-8 mol/L,10-10 mol/L and 10-12 mol/L).The cellular proliferation was detected with MTT assay after 1,3,5,7 and 9 days.The cells were identified with cell immunochemistry and Western Blot to find out the most effective concentration of NPY at different time points under osteoblastic condition.The cells were then divided into 4 groups:PBS,NPY,NPY + NPY receptor antagonist,and NPY + DKK1.Western blot was used to determine the expression of β3-catenin and p-GSK-3β in each group.Nuclear signaling activity of β3-catenin was observed using immunofluorescence staining.Results NPY significantly improved the proliferation of MC3T3-E1 cells at 7 and 9 days (P <0.05).NPY (10s mol/L and 10-10 mol/L) groups and NPY (10-10 mol/L and 10-12 mol/L) groups significantly improved the ALP activity at 4 and 14 days respectively (P < 0.05).At 4 days,the expression of ALP protein was significantly decreased in the NPY + DKK1 group and the NPY + NPY receptor antagonist group compared with that in the NPY group (P < 0.05).Although the expression levels of [β-catenin and p-GSK-3β protein were uninfluenced in either case,NPY significantly stimulated the nuclear signaling activity of β3-catenin.Conclusions NPY may significantly increase the expression of ALP protein in MC3T3-E1 ceils during osteoblastic differentiation.This effect might be mediated through the canonical Wnt signaling pathway.

Chinese Journal of Hospital Administration 2017;33(11):851-855
Objective To explore nurses′ perceptions of patient safety culture in emergency departments at tertiary hospitals in Sichuan province. Methods By convenient sampling method,a total of 210 emergency nurses from 6 tertiary hospitals in Sichuan province were investigated with a general data questionnaire and a hospital survey on patient safety scale. Results 68.10% of the emergency nurses had positive perceptions of patient safety culture, as evidenced by the following indicators. The organization learning and continuous improvement (74. 27%), hospital management support for patient safety (72.70%), supervisor/manager expectations and actions promoting safety (78.10%), were the safety culture areas with higher percentage of positive response. Areas of non-punitive response to errors (19.67%), staffing (41.08%) had the lowest percentage of positive response. There were significant differences between such groups as years of working, education background and job title. Conclusions Patient safety culture should be improved in the emergency departments of the tertiary hospitals in Sichuan province,especially in the adverse events reporting system and staffing problem. Safety training deserves greater attention in nurses with less working experience, education background or job title in emergency departments.

OBJECTIVE:
To explore the genetic mechanism underlying a case with para-Bombay phenotype.
METHODS:
The ABO and Lewis phenotype were identified with serological methods. The coding regions of exons 6 and 7 of the ABO and FUT1 genes were amplified with PCR and directly sequenced. Haploid sequence analysis was carried out on the variant sites of the FUT1 gene.
RESULTS:
Serological analysis confirmed that the proband has a rare para-Bombay phenotype. Direct sequencing revealed that he was a B.01/O.01.02 heterozygote for the ABO gene, and had heterozygous deletion for the 768 and 881-882 sites of the FUT1 gene. Further haploid analysis showed that the c.881_882delTT deletion has occurred in one haploid while c.768delC was present in the other haploid. The proband was therefore determined as a FUT1*01N.13/01N.20 heterozygote, which have resulted in frameshift in polypeptide chain p.Phe294Cysfs*40 and p.Val257Phefs*23, respectively.
CONCLUSION
A rare bi-allelic heterozygous deletion of para-Bombay phenotype has been identified in a blood donor. The c.881_882delTT and c.768delC deletions may decrease the activity of α-1,2-fucosyltransferase.

Objective:To investigate the efficacy of immune checkpoint inhibitor maintenance therapy after radical radiotherapy and chemotherapy for stage Ⅲ-ⅣA esophageal squamous cell carcinoma (ESCC) in the real world.Methods:The clinical data of 65 patients with stage Ⅲ-ⅣA ESCC treated by radical radiotherapy and chemotherapy from January 1, 2018 to December 31, 2022 in Hefei Cancer Hospital, Chinese Academy of Sciences were retrospectively analyzed. According to whether to undergo immune checkpoint inhibitor maintenance therapy after radical radiotherapy and chemotherapy, the patients were divided into a control group ( n=29) and an immune maintenance therapy group ( n=36) . The objective response rate (ORR) , progression-free survival (PFS) , and overall survival (OS) between the two groups were compared. Kaplan-Meier method was used to draw the survival curve accompanied with log-rank test. Cox regression model was used to conduct both univariate and multivariate analyses. Results:The ORR was 34.5% (10/29) in the control group and 61.1% (22/36) in the immune maintenance therapy group, with a statistically significant difference ( χ2=4.56, P=0.032) . The median PFS of control group and immune maintenance therapy group were 7.2 and 17.9 months, respectively, with a statistically significant difference ( χ2=7.86, P=0.005) . The median OS was 14.1 and 27.8 months, respectively, with a statistically significant difference ( χ2=5.40, P=0.020) . Univariate analysis showed that, objective response ( HR=0.09, 95% CI: 0.03-0.28, P<0.001) and immune maintenance therapy ( HR=0.38, 95% CI: 0.17-0.88, P=0.024) were the influential factors of OS in ESCC patients treaded by radical chemoradiotherapy in stage Ⅲ-ⅣA. Multivariate analysis showed that, objective response ( HR=0.09, 95% CI: 0.03-0.29, P<0.001) and immune maintenance therapy ( HR=0.40, 95% CI: 0.17-0.92, P=0.032) were the independent influencing factors for OS in ESCC patients treaded by radical chemoracial therapy in stage Ⅲ-ⅣA. The incidence of adverse reactions was 22.22% (8/36) in the immune maintenance therapy group and 10.34% (3/29) in the control group, with no statistically significant difference ( χ2=1.61, P=0.204) . All the adverse reactions were grade 1-2, and the symptoms were relieved after symptomatic treatment. Conclusion:Maintenance therapy with immune checkpoint inhibitors after radical chemoradiotherapy of stage Ⅲ-ⅣA ESCC can significantly improve the prognosis of patients with good safety.

Objective:To evaluate internal fixation via only the modified Stoppa approach in the treatment of central hip dislocation complicated with fracture of the posterior acetabular wall.Methods:A retrospective study was conducted in the 13 patients with central hip dislocation and fracture of the posterior acetabular wall who had been treated at Department of Orthopedic Trauma, Nanfang Hospital between February 2015 and February 2018. They were 10 men and 3 women, aged from 31 to 65 years (average, 46.7 years). All patients were treated with internal fixation via only the modified Stoppa approach. The reduction of double-column and posterior wall fractures was evaluated according to the X-ray Matta scoring system, as well as to the Wiberg central-edge (CE) angles between the vertical line of the center point of the femoral head and the lateral edge of the acetabulum and acetabular tolerance on the normal and affected sides immediately after operation; the hip function was evaluated by the modified Merle d'Aubigne and Postel scoring system at 12 months after operation.Results:All patients were followed up for 16 to 52 months (average, 25.6 months). In all of them, reduction and fixation of central hip dislocation and acetabular fracture was completed successfully, and indirect reduction of posterior wall fracture and acetabular tolerance were satisfactory. Operation time ranged from 130 to 270 min, averaging 155.5 min; intraoperative blood loss from 600 to 5,600 mL, averaging 1,150.5 mL; intraoperative infusion of concentrated red blood cells from 2 to 12 U, averaging 6 U. By the X-ray Matta scoring system immediately after operation, anatomical reduction was achieved in 4 posterior wall fractures and satisfactory reduction in 9 ones. There was no significant difference between the normal and affected sides in the CE angle (43.53°±3.46° for the affected side versus 43.19°±3.28° for the normal side) or in the acetabular tolerance (76.56%±15.50% for the affected side versus 75.32%±16.24% for the normal side) ( P>0.05). The modified Merle d'Aubigne and Postel scores at 12 months after operation ranged from 12 to 18 points, averaging 16.5 points; the hip function was assessed as excellent in 9 cases, as good in 3 and as fair in one. By the last follow-up, none of the 13 patients lost fracture reduction, and their internal fixation was firm with no loosening or breakage. Conclusion:In the treatment of central hip dislocation complicated with fracture of the posterior acetabular wall, internal fixation via only the modified Stoppa approach can lead to satisfactory fracture reduction, firm fixation, good hip joint tolerance, and fine clinical efficacy.

ObjectiveTo investigate the effect and possible mechanism of Shenfu Injection (参附注射液) on rat cardiomyocyte injury induced by isoproterenol from the perspective of regulating the high mobility group protein B1 (HMGB1)/ Toll-like receptor 4 (TLR4)/nuclear factor κB (NF-κB) pathway through the deacetylation modification of silent information regulator 1 (SIRT1). MethodsThe optimal concentration and intervention duration of isoproterenol hydrochloride and the optimal intervention concentration of Shenfu Injection were screened out by CCK-8 method. Logarithmically growing H9c2 rat cardiomyocytes were taken at 5×104 cells/well and divided into normal group, model group, Shenfu Injection group, and SIRT1 inhibitor group, with 3 replicates in each group.Except for the normal group, the cells in the other groups were induced by isoproterenol hydrochloride to establish a chronic heart failure cell model. After modeling, the Shenfu Injection group was given Shenfu Injection at the optimal intervention concentration, and the SIRT1 inhibitor group was given 1 μmol/L of SIRT1 inhibitor EX-527, for optimal intervention duration.CCK-8 assay was used to detect the cell activity and calculate the inhibitory rate. ELISA assay was used to detect the nicotinamide adenine dinucleotide oxidation state/ nicotinamide adenine dinucleotide reduction state (NAD+/NADH) in cardiomyocytes. Immunofluorescence was used to detect the immunofluorescence localization of HMGB1 and SIRT1 in cardiomyocytes. Western blotting was used to detect the protein expression of acetylated HMGB1 in cardiomyocytes, HMGB1 in the nucleus and cytoplasm, and SIRT1, TLR4, myeloid differentiation factor 88 (MYD88) and NF-κB p65 in cardiomyocytes. RT-qPCR was used to detect the mRNA expression of SIRT1, HMGB1, TLR4, MYD88 and NF-κB p65 in cardiomyocytes. ResultsThe optimal intervention concentration of isoproterenol hydrochloride was 300 μmol/L, and the intervention duration was 48 hours; 8% was the optimal intervention concentration of Shenfu Injection. Compared to those in the normal group, the cell activity, NAD+/NADH value, nuclear HMGB1 protein expression, cardiomyocyte SIRT1 protein and mRNA expression in the model group decreased, while the cell inhibition rate, cardiomyocyte acetylated HMGB1 and cytoplasmic HMGB1 protein expression, cardiomyocyte TLR4, MYD88, NF-κB p65 protein and mRNA expression all increased (P<0.05); fluorescence localization showed that the content of HMGB1 in cardiomyocytes in the model group increased and was localized in both the nucleus and cytoplasm.Compared to the model group and the SIRT1 inhibitor group, the Shenfu Injection group showed significant improvements in all the above indicators (P<0.05); fluorescence localization showed that the SIRT1 content increased in the Shenfu injection group, while the HMGB1 content decreased, and was mainly located in the nucleus. ConclusionShenfu Injection can improve myocardial cell damage by increasing SIRT1 expression to reduce the acetylation level of HMGB1, regulating the HMGB1/TLR4/NF-κB pathway and inhibiting the nuclear translocation of HMGB1.
