Objective:To explore the organizational identity, sense of coherence, perceived social support, and work engagement of surgical nurses in a traditional Chinese medicine hospital and the relationships between them.Methods:From March to May 2022, 450 surgical nurses were selected by convenience sampling from Guangdong Provincial Hospital of Traditional Chinese Medicine for a survey with a general information questionnaire, the Organizational Identification Scale, the Sense of Coherence Scale, the Perceived Social Support Scale, and the Utrecht Work Engagement Scale-9. SPSS 24.0 was used to perform Pearson correlation analysis. AMOS 24.0 was used for structural equation modeling.Results:The nurses' scores of organizational identity, sense of coherence, perceived social support, and work engagement were (26.00±5.00), (53.58±7.50), (47.47±7.50), and (30.06±1.00), respectively. The correlation analysis revealed positive correlations between organizational identity, sense of coherence, perceived social support, and work engagement ( r=0.369-0.741, all P<0.001). Sense of coherence played a partial mediating role between perceived social support and work engagement, and the mediating effect was 0.07, accounting for 12.07% of the total effect. Organizational identity and sense of coherence produced a chain mediating effect between perceived social support and work engagement, in which the mediating effect was 0.11, accounting for 18.97% of the total effect. Conclusions:Organizational identity and sense of coherence produce a chain mediating effect between perceived social support and work engagement in the surgical nurses of the traditional Chinese medicine hospital.

Objective To collect the serum samples of patients with nonalcoholic fatty liver disease (NAFLD), and to investigate the changes in serum metabolic biomarkers before and after lifestyle intervention. Methods A total of 23 patients who were diagnosed with NAFLD in Department of Gastroenterology and Inpatient Department, Putuo District Central Hospital of Shanghai, from January 2019 to January 2020 were enrolled, and all patients received the intervention with aerobic exercise and equicaloric low-carbohydrate high-protein diet. A total of 13 healthy volunteers who underwent physical examination in Physical Examination Center were enrolled as control group. For the patients with NAFLD, basic information was collected before and after intervention, blood samples were collected twice to measure liver function, blood glucose, and blood lipids, and part of serum was used for serum metabolomics analysis. The serum samples were analyzed by ultra-performance liquid chromatography/tandem high-resolution mass spectrometry. The data collected were processed in Compound Discover, and then principal component analysis (PCA) and orthogonal partial least squares discriminant analysis were used to establish the profile of differentially expressed blood metabolites between patients and healthy people and perform the enrichment analysis of differentially expressed metabolic pathways. The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon non-parametric test was used for comparison of non-normally distributed continuous data between two groups. Results After lifestyle intervention, the patients had significant reductions in body mass index ( P < 0.01), body weight ( P < 0.01), and serum biochemical parameters alkaline phosphatase, albumin, gamma-glutamyl transpeptidase, and alanine aminotransferase (all P < 0.05), as well as a significant reduction in total protein ( P < 0.01), while there were no significant improvements in cholinesterase, aspartate aminotransferase, and glucose. As for the four items for blood lipids, there was a significant reduction in triglyceride ( P < 0.01), while there were no significant improvements in high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and total cholesterol. The metabolomics analysis showed that 33 serum metabolites changed significantly after lifestyle intervention. In addition, PCA results showed that after intervention, the level of metabolites in patients tended to be normal. The signaling pathway analysis showed that exercise and diet mainly affected the pathways of bile acid, unsaturated fatty acid synthesis, and phenylalanine metabolism. Conclusion Lifestyle intervention can achieve varying degrees of reduction in the body weight of patients with NAFLD, improve serum biochemical parameters, and regulate the abnormal metabolic pathway in patients with NAFLD, which has important clinical value and significance for guiding clinicians to formulate reasonable diet and exercise strategies for patients with NAFLD and prevent the progression of NAFLD.

Objective: To explore a model that workplace social capital is associated with intention to stay (ITS) in the nursing profession and that this association is partially mediated by organizational commitment, job satisfaction, and job stress among Chinese nurses. Methods: A cross-sectional, observationalstudy was conducted in Shanghai, China between September and December 2014. Two thousandforty-two nurses from 23 healthcare organizations were recruited for the current study using a two-stage sampling process.Intention to stay, workplace social capital, job satisfaction, organizational commitment, and job stress was measured by validated scale. Measured variable path analysis (MVPA) was used to test their hypothesized relationships. Results: There were significant positive direct effects from workplace social capital (=0.11, P<0.01) , organizational commitment (=0.81, P<0.01) and job satisfaction (=0.03, P<0.01) to ITS, and a negative direct effects from job strain to ITS (=-0.03, P<0.01) . The model explained 84% of the variability in ITS. Additionally, workplace social capital had significant positive direct effects on organizational commitment (=0.65, P<0.01) , job satisfaction (=0.44, P<0.01) and negative direct effects on job strain (=-0.35, P<0.01) . The indirect effect of social capital to ITS was 0.55. Job satisfaction was positively associated with organizational commitment (r=0.47, P<0.01) , and negtively associated with job stress (r=-0.12, P<0.01) . Job stress was negtively associated with organizational commitment (r=-0.20, P<0.01) . Conclusion This study suggests that greater workplace social capital may lead to higher ITS in nursing primarily by increasing commitment to the nursing occupation and their job satisfaction and by reducing their sense of job stress.

Objective · To establish human cervical cancer xenografts in nude mice and investigate the antitumor therapeutic effects and safety of EGF modified cisplatin-alginate conjugate liposomes. Methods · Cervical cancer-bearing mouse model was established by subcutaneously injecting Hela cells in nude mice. Generalstate and xenograft growth of the mice were observed. Tumor volumes, tumor weights, and the body weights of mice during the treatment were recorded and analyzed. The expression levels of EGFR in xenografts were detected by immunohistochemistry. Results · ① EGFR was highly expressed in the xenografts. ② CS-EGF-Lip inhibited the tumor growth effectively (P=0.000). ③ The inhibition rates of tumor volume and tumor weight of CS-EGF-Lip were 80.22% and 58.60% respectively, which were betterthan those of cisplatin (P=0.000). ④ CS-EGF-Lip had minimal influence on body weight in mice (P=0.000). Conclusion · CS-EGF-Lip has more effective antitumoreffects than cisplatin in cervical cancer-bearing mice, which can inhibit tumor growth of solid tumors with enhanced efficacy and safety.

BACKGROUNDAs an X-linked recessive way, arginine vasopressin receptor 2 (AVPR2) gene mutation resulted in a hereditary disease - congenital nephrogenic diabetes insipidus (CNDI). We found a suspect clinical CNDI pedigree. In order to identify the genetic etiology, we performed the genetic analysis.

METHODSThe clinical features of the proband and his family members were recorded. The laboratory tests and imaging inspections were analyzed. The water deprivation and pituitrin loading test were performed in the proband and his brother. The genomic DNA of all the members of the pedigree was extracted and then PCR amplification on AVPR2 gene was carried out. Sequencing in both directions was performed to identify mutation on AVPR2 gene.

RESULTSBoth the proband and his brother were diagnosed as CNDI, meanwhile the other members of this pedigree were normal. No severe biochemical abnormality was found in the two CNDI patients. Both the patients had moderate urinary retention, severe megaloureter and hydronephrosis, and mild renal insufficiency. Two mutations of AVPR2 gene were discovered in the 3rd exon in the patients, a silent mutation L309L and a nonsense mutation R337X. The AVPR2 gene R337X mutation was co-segregated with CNDI. R337X mutation was not a reported mutation in the mainland of China.

CONCLUSIONThe AVPR2 gene R337X mutation was also a genetic etiology of CNDI patients in the mainland of China.
