Objective To explore the interaction model of social capital, mental health,occupational burnout, turnover intention and the related influence factors on nurses. Methods By random cluster sampling, investigated 723 nurses with Nurses' Turnover Intention Inventory, the Maslach Burnout Inventory, Social Capital Questionnaire and Chinese Health Questionnaire, then explored the interaction model by path analysis. Results Nurses' position can influence their social capital(the path coefficient was 0. 124), social capital and occupational turnout can influence nurses' mental health(the path coefficient were -0. 231,0. 151), the mental health and occupational turnout both can influence nurses' turnover intention directly(the path coefficient were 0. 088,0. 151 ), the model is acceptable(CMIN/DF 1. 645, GFI 0. 984, AGFI 0. 966, IFI 0. 941, CFI 0. 937, RMSEA 0. 037).Conclusion Social capital can provide a new perspective for nurses' management, developing the social capital resources can relieve nurses' mental problems effectively; relieving the turnout and mental problem can decrease nurses' turnover intention finally.

[ ABSTRACT] AIM: To investigate the role of anterior thalamic nucleus in trigeminal nerve electrostimulation ( TNS)-induced effects on seizures and hippocampal damage.METHODS: The rats were intraperitoneally injected with pilocarpine to induce chronic epilepsy, and then received sham treatment, TNS treatment and TNS treatment after stereotac-tic lesion to the anterior thalamic nucleus.The TNS treatment lasted for 1 month in each group.Another injection of pilo-carpine was conducted to induce seizures, and the severity and duration of seizures were quantitatively evaluated.TUNEL, Fluoro-Jade B ( FJB) and Nissl staining were applied to determine in situ apoptosis, neuronal degeneration and neuron loss in the hippocampal CA1 area respectively.RESULTS:Compared with TNS group, TNS treatment after stereotactic lesion to the anterior thalamic nucleus significantly increased the severity and duration of seizures (P<0.05), and the numbers of TUNEL positive cells, FJB positive cells and lost neurons in the hippocampal CA1 area (P<0.01).CONCLUSION:Anterior thalamic nucleus plays a role in TNS-induced reduction of seizures and hippocampal damage.The mechanisms might be due to the chronically activation of the cortex through anterior thalamic nucleus pathway induced by TNS, resulting in the down-regulation of neuronal excitatory susceptibility.

Objective To understand the potential risk for schistosomiasis transmission caused by introduction of infection source from mobile population in Shanghai. Methods Field investigation was conducted in the suburb of Shanghai City by screening the mobile population living in Shanghai for more than 1 month and over 1 years old in a procedure of interviewing, serum indirect hemagglutination (IHA) test, and then fecal examination to detect the eggs with nylon sedimentation approach for those IHA positives. Results Among 2 931 mobile people investigated, 1 575 were male (53.74%) and 1 356 were female(46.26%); 138 out of 2 931 were positive in IHA test (4.71%). 1 938 (66.12%) out of 2 931 came from Schistosoma japonicum-endemic provinces and its positive rate in mobile population (5.99%) was significantly higher than those from the transmission-interrupted provinces (2.6%) (?2=10.28, P

Objective:To explore the effect of cold-strap endoscopic mucosal resection (CS-EMR) in patients with colorectal polyps.Methods:A prospective randomized clinical trial was conducted to 320 selected patients with colorectal polyps diagnosed by Shenzhen Luohu District People′s Hospital from May 2019 to June 2021. The patients were randomly divided into CS-EMR group and HS-EMR group with 160 cases each, using a random number table generated by Excel 2007. The main parameters for statistical analysis contain the process indicators of the two groups of surgical methods, the complete polypectomy rate of patients after surgery, the degree of postoperative pain and the recovery of gastrointestinal function, and the differences in surgical complications.Results:The polypectomy time of CS-EMR group was shorter than that of HS-EMR group: (4.11 ± 1.20) min vs. (4.42 ± 0.98) min, with a statistically significant difference ( P<0.05). The score of visual analogue pain scale (VAS) in CS-EMR group was lower than that in HS-EMR group at 4 and 12 hours after operation: (3.11 ± 0.78) scores vs. (3.48 ± 0.80) scores, (3.38 ± 0.80) scores vs. (3.61 ± 0.92) scores, with a statistically significant difference ( P<0.05). The first anal exhaust time and first defecation time in CS-EMR group were lower than those in HS-EMR group: (27.83 ± 5.01) h vs. (29.66 ± 4.84) h, (43.73 ± 7.80) h vs. (47.28 ± 8.14) h, with a statistically significant difference ( P<0.05). The complications in CS-EMR group were significantly lower than those in HS-EMR group: 5.63% (9/160) vs. 12.50% (20/160), with a statistically significant difference ( P<0.05). Conclusions:The effect of CS-EMR in the treatment of colorectal polyps is not different from that of HS-EMR, but the former has the advantages of short resection time, rapid recovery of gastrointestinal function after operation, light pain and less complications.

Objective:To explore the relationship between genotypes and phenotypes in hypertrophic cardiomyopathy(HCM) patients using whole exome sequencing(WES) and three-dimensional speckle-tracking echocardiography(3D-STE).Methods:Twenty patients with apical HCM(ApHCM) and 25 patients with non-apical HCM(non-ApHCM) from June 2018 to January 2019 in Zhongshan Hospital of Fudan University were enrolled. All subjects underwent venous blood sampling and WES. Regular two-dimensional echocardiography was performed to acquire the following parameters: interventricular septum thickness, left ventricular posterior wall thickness, left ventricular end diastolic diameter, left ventricular end systolic diameter, the maximum thickness of left ventricular walls and left ventricular ejection fraction(LVEF). Full volume images were collected and then off-time analyzed with 3D-STE to acquire global longitudinal strain(GLS), global circumferential strain(GCS), twist and torsion. The relationships between above parameters, genotypes and phenotypes of left ventricle were analyzed.Results:Mutations were found in 73% of HCM patients.The two most common genes MYBPC3 and MYH7 accounted for 18% and 15% of mutations respectively. KCNEc.79C>T(p.Arg27Cys) and PRKAG2c.905G>A (p.Arg302Gln) were detected in both ApHCM group and non-ApHCM group. In ApHCM group, 60% of patients carried genetic mutations, which was significantly lower than non-ApHCM group(84%)( P=0.041). Compared with non-ApHCM group, GLS in ApHCM group was significantly higher ( P=0.008). There was no statistical difference of GLS between patients with mutations and without mutations( P=0.068). GLS demonstrated a moderate correlation with morphologic types of HCM(ApHCM and non-ApHCM)( r=0.364, P=0.012). However, there was no correlation between GLS and the condition of mutations( r=0.269, P=0.062). Conclusions:The relationship between genetics and phenotypic expression of HCM appears to be complex and heterogeneous. There are marked differences in gene mutations and systolic functions between ApHCM and non-ApHCM. The value of GLS correlates with the shape of left ventricle but not with genotypes.

Meridian theory plays an important role in the guidance of clinical practice of acupuncture and moxibustion. Since the publication of(), the meridian theory has been developed. In the paper, in view of complex science, the topological properties of acupoint-symptom network were analyzed quantitatively by taking acupoint as node and indication as the connection, such as high clustering coefficient and the small world effect. It was the first time to give the abstraction for the topological proof of the high efficiency information transmission property of acupoint-symptom network meridian system at different times. Its quantitative and digitalized significance was analyzed on the development of meridian theory under the complex scientific background so as to provide a new thought and method for the study of meridian theory and acupuncture modernization.
