Objective To explore the nurses'self-efficacy for palliative care and its related factors.Methods Data were collected via a self-constructed questionnaire,using the purposive sampling method.Subjects were nurses from two “grade-A” general hospitals in Henan province.Results The nurses' self-efficacy for palliative care stayed at a disequilibrium state,mean score of self-efficacy for physical care was 4.00,followed by family care self-efficacy 3.85,then psychological and spiritual care self-efficacy 3.70.Significant difference existed in self-efficacy for palliative care in nurses having different attitudes toward death.The cognitive level for palliative care,past experience of caring for end-stage patients were positively correlated with self-efficacy.Conclusions The main factors of the nurses' self-efficacy for palliative care related to attitudes toward death,past experience of caring for end-stage patients and the cognition level of nurses to palliative care.

Objective To investigate the relationships between occupational coping self-efficacy, job stress and core competence of nurses. Methods A total of 493 registered nurses were recruited in the survey with the Chinese nurse job stressors scale, occupational coping self-efficacy scale for nurses and competency inventory for registered nurse (CIRN). The correlations were analyzed using Pearson correlation analysis. Results The total scores on occupational coping self-efficacy, job stress of nurses and core competence of nurses were (31.94 ± 6.39), (90.29 ± 17.41) and (159.93 ± 34.31), respectively. Nurses′occupational coping self-efficacy negatively correlated with (r=-0.267, P<0.01) and positively correlated with the core competence of nurses (r=0.355, P<0.01). Conclusions The occupational coping self-efficacy of the nurses can be improved by successful experiencing, verbal persuasion and positive feedback. In this way, nurses core competence can be enhanced and their job stress can be relieved and consequently the quality of nursing can be enhanced.

Objective To explore the visinin-like protein-1 (VILIP-1) levels in the blood in the Alzheimer disease (AD) and mild cognitive impairment (MCI) due to AD patients,and also to explore its feasibility as a biomarker for the early diagnosis of AD and for the detection of progression of AD.Methods Fifty-eighty participants were included:20 cases for AD group,19 cases for MCI due to AD group,19 cases for normal control group.The level of VILIP-1 was tested by the ELISA method.Results The level of VILIP-1 in AD group was significantly higher than that in normal control group and MCI due to AD group:(9.0 ± 2.9) ng/L vs.(3.3 ± 1.7) and (6.5 ± 3.1) ng/L,and that in MCI due to AD group was significantly higher than that in normal group,there were statistical differences (P ＜ 0.01).The MMSE score in AD group was significantly lower than that in normal group and MCI due to AD group:(15 ± 3) scores vs.(27 ± 2) and (23 ± 2) scores,and that in MCI due to AD group was significantly lower than that in normal group,there were statistical differences (P ＜ 0.01).The level of VILIP-1 was negatively correlated with MMSE score (r =0.463,P ＜ 0.01),but positively correlated with age (r =0.417,P =0.01).Conclusions With the progression of the disease,the cognitive impairment of the AD patient is decreasing.VILIP-1 increased in the blood of the patients of AD and MCI due to AD.It means that the blood VILIP-1 could be a new and potential biomarker for the early diagnosis of AD,and it may be clinical useful for the early diagnosis and effective detection of AD to some extent.

Objective To evaluate the accuracy of respiratory variations of internal jugular vein (IJV) in monitoring fluid responsiveness in patients undergoing radical gastrectomy for gastric cancer.Methods Fifty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes,aged 40-64 yr,scheduled for elective radical gastrectomy for gastric cancer,were enrolled in this study.Before induction of anesthesia,the hemodynamic parameters such as heart rate,central venous pressure,cardiac index,stroke volume index (SVI),stroke volume variation and respiratory variation of IJV were recorded after haemodynamics was stable and were recorded again at 10 min after endotracheal intubation,and a loading dose of 6％ 130/0.4 hydroxyethyl starch 7 ml/kg was infused over 15 min.The parameters mentioned above were recorded within 5 min after loading dose.Patients were divided into 2 groups according to the percentage of increase in SVI (△SVI) after volume expansion:△SVI≥ 15％ was considered to be a positive response (responder group) and △SVI＜15％ was considered to be a negative response after volume expansion (non-responder group).Results The area under the receiver operating characteristic curve of respiratory variations of IJV in monitoring fluid responsiveness and 95％ confidence interval were 0.852 (0.744-0.961).Respiratory variation of IJV 24.6％ was considered as the cut-off value and used to monitor fluid responsiveness,and the sensitivity and specificity were 67.6％ and 92.3％,respectively.Conclusion Respiratory variation of IJV can be considered as an effective index in monitoring fluid responsiveness in the patients undergoing radical gastrectomy for gastric cancer.

Objective To investigate the expressions of a disintegrin and metalloprotease 17 (ADAM17) and epidermal growth factor recepter (EGFR) in human esophageal squamous cell carcinoma (ESC),and to explore their relationship with clinicopathological characteristics.Methods The paraffin specimens in postoperative pathological tissues of 66 ESC patients in the Third People's Hospital of Hefei from January 2013 to December 2017 were selected.Expressions of ADAM17 and EGFR proteins were examined by using immunohistochemistry in 66 cases of ESC tissues and 33 cases of adjacent tissues of the tumors.The relationship of ADAM17 and EGFR with clinicopathological features was analyzed.Kendall method was used to detect the expression correlation of ADAM17 and EGFR.Results The positive rate of ADAM17 protein in ESC tissues was higher than that in the adjacent tissues of the tumors [68.2 ％ (45/66) vs.33.3 ％ (11/33),x2 =10.874,P =0.001].The positive rate of EGFR protein in ESC tissues was higher than that in the adjacent tissues of the tumors [66.7 ％ (44/66) vs.39.4 ％ (13/33),x2 =6.699,P =0.01].The expressions of ADAM17 and EGFR protein were related with ESC pathological TNM staging,infiltration depth,lymph node metastasis (x2 =4.797,4.890,6.089;8.790,8.766,10.154,respectively,all P ＜ 0.05).ADAM17 expression was positively correlated with EGFR protein (r,=0.368,P ＜ 0.05).Conclusions ADAM17 and EGFR are highly expressed in human ESC.Besides,ADAM17 and EGFR have the interaction in the occurrence and development of esophageal cancer.Joint detection may help to determine the degree of metastasis and evaluate prognosis.

Objective To investigate the the preventive and management methods of pure-NOTES transanal total mesorectal excision (pure-NOTES TaTME) with postoperative anastomotic complications.Methods Retrospectively analyzed the clinical data of 59 cases with low and middle rectal cancer who were underment pure-NOTES TaTME in Linzi District People's Hospital,and discussed the situction of the complications.Results Postoperative anastomotic complications were occurred in 3 cases,anastomotic leakage in 1 case,anastomotic stenosis in 1 case,anastomotic stenosis and leakage in 1 case,accounting for 5.1％.Conclusions For suitable rectal neoplasms patients,pure-NOTES TaTME operation doesn't increase the incidence of anastomotic complication,and it's is safe and feasible.Preoperative preparation,good blood supply,tension-free anastomosis,and correct choice and using of stapler and anastomotic drainage tube are the key to reduce anastomotic complications.

PURPOSE: Follistatin-like protein 1 (FSTL1) is a secreted glycoprotein that has been shown to play a role in various types of cancer. However, the clinical significance and function of FSTL1 in breast cancer have not been reported. We investigated the role of FSTL1 in breast cancer in this study. METHODS: Enzyme-linked immunosorbent assays, western blot analysis, and reverse transcription polymerase chain reaction were used to monitor the expression of FSTL1 in breast cancer tissue and in serum samples from breast cancer patients. We employed a 4T1 breast cancer model and Fstl1(+/−) mice for in vivo studies. Hematoxylin and eosin staining, western blot analysis, and RNA sequencing were used to analyze the effect of FSTL1 on primary tumor growth and lung metastasis. RESULTS: We demonstrated that the expression of FSTL1 is reduced in both the breast cancer tissue and the serum of breast cancer patients. We showed that reduced levels of FSTL1 in serum correlate with elevated expression of Ki-67 and epidermal growth factor receptor (EGFR) in cancer tissues. Moreover, lowered expression of FSTL1 was associated with decreased survival in breast cancer patients. Experiments on the Fstl1(+/−) mouse model established that FSTL1 deficiency had no effect on primary tumor growth, but increased the lung metastases of breast cancer cells, resulting in reduced survival of tumor-bearing mice. RNA sequencing found significantly reduced expression of Egln3 and increased expression of EGFR in Fstl1(+/−) mice. Thus, our results suggest that FSTL1 may affect the expression of EGFR through Egln3, inhibiting the proliferation of breast cancer cells at lung metastatic sites. CONCLUSION: In conclusion, we suggest a suppressor role of FSTL1 in breast cancer lung metastasis. Furthermore, FSTL1 may represent a potential prognostic biomarker and a candidate therapeutic target in breast cancer patients.

Objective The preventive effect of epigallocatechin gallate(EGCG)on hyperglycemia-induced hemorrhagic transformation(HT)was analyzed,and the underlying mechanisms were further explored.Methods Male SD rats were randomly divided into sham operation group(Sham,n = 20),model group(n = 27),hyperglycemia model group(HG,n = 43),and EGCG group(n = 43).In the model group,only the electrocoagulation cerebral ischemia model was established,and the HG group and the EGCG group were used to establish the HT model with acute hyperglycemia combined with electrocoagulation cerebral ischemia model.In addition,EGCG was adminis-tered by gavage for 5 days before cerebral ischemia at a dose of 50 mg/kg/d.Further studies confirmed the relevant targets by using network pharmacology to predict the potential targets and pathways of EGCG in the occurrence of HT.Results Compared with the model group,the mortality rate of the rats in the HG group was significantly increased[21.2%(6/27)vs.51.2%(22/43),P＜0.05].The mortality of rats in the EGCG group was significantly lower than that in the HG group[30.20%(13/43)vs.51.2%(22/43),P＜0.05].Second,mNSS,Longa score and infarct volume in the EGCG group were significantly lower than those in the HG group(P＜0.05).The incidence of HT in the HG group was higher than that in the model group(59.3%vs.90.7%).EGCG significantly reduced the incidence of hyperglycemia-induced HT to 69.8%.Compared with the HG group,EGCG decreased the hemoglobin content from(53.42±5.11)mg/dL to(37.04±2.39)mg/dL respectively(P＜0.05).Network pharmacology revealed that Nrf2-Keap1-mediated neuroinflammation may be associated with hyperglycemia-induced HT.The expression of Nrf2 and Keap1 was significantly decreased and the expression of TLR4 and phosphorylation of NF-κB was significantly increased in the HG group,but EGCG reversed this process.Conclusion EGCG pretreatment prevents the occurrence of HT,which may be related to the neuroprotection mediated by activation of the Nrf2-Keap1 signaling pathway.

Objective:To investigate respiratory virus infection in children with septic shock in pediatric care units (PICU) in China and its influence on clinical outcomes.Methods:The clinical data of children with septic shock in children′s PICU from January 2018 to December 2019 in 10 Chinese hospitals were retrospectively collected. They were divided into the pre-COVID-19 and post-COVID-19 groups according to the onset of disease, and the characteristics and composition of respiratory virus in the 2 groups were compared. Matching age, malignant underlying diseases, bacteria, fungi and other viruses, a new database was generated using 1∶1 propensity score matching method. The children were divided into the respiratory virus group and non-respiratory virus group according to the presence or absence of respiratory virus infection; their clinical characteristics, diagnosis, and treatment were compared by t-test, rank sum test and Chi-square test. The correlation between respiratory virus infection and the clinical outcomes was analyzed by logistic regression. Results:A total of 1 247 children with septic shock were included in the study, of them 748 were male; the age was 37 (11, 105) months. In the pre-and post-COVID-19 groups, there were 530 and 717 cases of septic shock, respectively; the positive rate of respiratory virus was 14.9% (79 cases) and 9.8% (70 cases); the seasonal distribution of septic shock was 28.9% (153/530) and 25.9% (185/717) in autumn, and 30.3% (161/530) and 28.3% (203/717) in winter, respectively, and the corresponding positive rates of respiratory viruses were 19.6% (30/153) and 15.7% (29/185) in autumn, and 21.1% (34/161) and 15.3% (31/203) in winter, respectively. The positive rates of influenza virus and adenovirus in the post-COVID-19 group were lower than those in the pre-COVID-19 group (2.1% (15/717) vs. 7.5% (40/530), and 0.7% (5/717) vs. 3.2% (17/530), χ2=21.51 and 11.08, respectively; all P<0.05). Rhinovirus virus were higher than those in the pre-Covid-19 group (1.7% (12/717) vs. 0.2% (1/530), χ2=6.51, P=0.011). After propensity score matching, there were 147 cases in both the respiratory virus group and the non-respiratory virus group. Rate of respiratory failure, acute respiratory distress, rate of disseminated coagulation dysfunction, and immunoglobulin usage of the respiratory virus group were higher than those of non-respiratory virus group (77.6% (114/147) vs. 59.2% (87/147), 17.7% (26/147) vs. 4.1% (6/147), 15.6% (25/147) vs. 4.1% (7/147), and 35.4% (52/147) vs. 21.4% (32/147); χ2=11.07, 14.02, 11.06 and 6.67, all P<0.05); and PICU hospitalization of the former was longer than that of the later (7 (3, 16) vs. 3 (1, 7)d, Z=5.01, P<0.001). Univariate logistic regression analysis showed that the presence of respiratory viral infection was associated with respiratory failure, disseminated coagulation dysfunction, the use of mechanical ventilation, and the use of immunoglobulin and anti-respiratory viral drugs ( OR=2.42, 0.22, 0.25, 0.56 and 1.12, all P<0.05). Conclusions:The composition of respiratory virus infection in children with septic shock is different between pre and post-COVID-19. Respiratory viral infection is associated with organ dysfunction in children with septic shock. Decreasing respiratory viral infection through respiratory protection may improve the clinical outcome of these children.

Objective:To investigate the clinical features, pathogen composition, and prognosis of septic shock in pediatric intensive care units (PICU) in China.Methods:A multicenter retrospective cohort study. A retrospective analysis was conducted on the clinical data of children with septic shock from 10 hospitals in China between January 2018 and December 2021. The clinical features, pathogen composition, and outcomes were collected. Patients were categorized into malignant tumor and non-malignant tumor groups, as well as survival and mortality groups. T test, Mann Whitney U test or Chi square test were used respectively for comparing clinical characteristics and prognosis between 2 groups. Multiple Logistic regression was used to identify risk factors for mortality. Results:A total of 1 247 children with septic shock were included, with 748 males (59.9%) and the age of 3.1 (0.9, 8.8) years. The in-patient mortality rate was 23.2% (289 cases). The overall pathogen positive rate was 68.2% (851 cases), with 1 229 pathogens identified. Bacterial accounted for 61.4% (754 strains) and virus for 24.8% (305 strains). Among all bacterium, Gram negative bacteria constituted 64.2% (484 strains), with Pseudomonas aeruginosa and Enterobacter being the most common; Gram positive bacteria comprised 35.8% (270 strains), primarily Streptococcus and Staphylococcus species. Influenza virus (86 strains (28.2%)), Epstein-Barr virus (53 strains (17.4%)), and respiratory syncytial virus (46 strains (17.1%)) were the top three viruses. Children with malignant tumors were older and had higher pediatric risk of mortality (PRISM) Ⅲ score, paediatric sequential organ failure assessment (pSOFA) score (7.9 (4.3, 11.8) vs. 2.3 (0.8, 7.5) years old, 22 (16, 26) vs. 16 (10, 24) points, 10 (5, 14) vs. 8 (4, 12) points, Z=11.32, 0.87, 4.00, all P<0.05), and higher pathogen positive rate, and in-hospital mortality (77.7% (240/309) vs. 65.1% (611/938), 29.7% (92/309) vs. 21.0% (197/938), χ2=16.84, 10.04, both P<0.05) compared to the non-tumor group. In the death group, the score of PRISM Ⅲ, pSOFA (16 (22, 29) vs. 14 (10, 20) points, 8 (12, 15) vs. 6 (3, 9) points, Z=4.92, 11.88, both P<0.05) were all higher, and presence of neoplastic disease, positive rate of pathogen and proportion of invasive mechanical ventilation in death group were also all higher than those in survival group (29.7% (87/289) vs. 23.2% (222/958), 77.8% (225/289) vs. 65.4% (626/958), 73.7% (213/289) vs. 50.6% (485/958), χ2=5.72, 16.03, 49.98, all P<0.05). Multiple Logistic regression showed that PRISM Ⅲ, pSOFA, and malignant tumor were the independent risk factors for mortality ( OR=1.04, 1.09, 0.67, 95% CI 1.01-1.05, 1.04-1.12, 0.47-0.94, all P<0.05). Conclusions:Bacterial infection are predominant in pediatric septic shock, but viral infection are also significant. Children with malignancies are more severe and resource consumptive. The overall mortality rate for pediatric septic shock remains high, and mortality are associated with malignant tumor, PRISM Ⅲ and pSOFA scores.
