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.

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 investigate the serological and molecular genetic characteristics of a voluntary blood donor with combined FUT1 and ABO blood group gene variants causing para-Bombay and A2 subtype, and to review relevant literature on para-Bombay blood types carrying alleles such as FUT101W.37 and FUT101W.23. Methods:A blood donor with para-Bombay and A 2 subtype who participated in voluntary blood donation at the Dongguan Blood Center in August 2023 was selected as the study subject. Serological tests were performed to identify the ABO blood group, Lewis blood group antigens, and unexpected serum antibodies in the donor. Adsorption-elution test was conducted to detect trace antibodies in the blood donor′s plasma to trace the A, B and H antigens on the red blood cell surface. Sanger sequencing was carried out to analyze the sequences of the FUT1 and ABO genes. Using keywords such as " para-Bombay" " FUT1*01W.37" and " FUT1*01W.23" both in Chinese and English, relevant literature on para-Bombay blood type subjects carrying FUT1*01W.37 and FUT1*01W.23 alleles was retrieved from the CNKI, Wanfang Data Knowledge Service Platform, and PubMed databases, and the retrieval time was set as from the establishment of database to December 2022. This study has been approved by the Ethics Committee of Dongguan Blood Center (No. 2022005), and informed consent of blood donation was obtained from the blood donor. Results:Serological testing of the blood donor revealed inconsistent results between forward and reverse ABO blood typing, negative H antigen on the red blood cell surface, Le(a-b+ ) secretor type for Lewis blood group, and unexpected anti-H antibodies in the plasma, indicating a suspected para-Bombay type. Absorption-elution test suggested the blood type of the blood donor to be para-Bombay and A subtype. Sanger sequencing showed that the donor has harbored homozygous FUT1*(c.35T+ c.803A)/(c.35T+ c.803A) variant, with the FUT1*(c.35T+ c.803A) allele containing a dual nucleotide variant unrecorded by the International Society of Blood Transfusion (ISBT) FUT1 gene variant database, which was similar to the weakly functional allele of FUT101W. 37(c.803G>A) as recorded by the ISBT database. The ABO genotype was heterozygous ABOA2.05/O.01.02. Combining the results of serological and genetic testing, the blood type of the blood donor was determined to be para-Bombay and A 2 subtypes. Literature review has identified a pregnant women from Qingdao carrying the FUT1*01W.37 allele and 2 individuals carrying a heterozygous FUT1*01W.23 allele. Conclusion:This study has discovered a blood donor with coexisting para-Bombay and ABO subtype blood groups. Based on the characteristics of red blood cell surface antigens, the FUT1*01W.37 as classified as an FUT1 null allele.
