Objective To investigate the statistical.method for analyzing nurse job burnout Data. Methods Hotelling T2 test and multivariate analysis of variance(MANOVA)were used to analyze nurse job burnout datum. Results There was statistical significance between different cities,different ethnieities in the personal achievements,hut from three dimensions of the whole job burnout,there are no statistical sig-nificant differences among different cities, different ethnicities and different ages. Conclusions The use of Hotelling T2 test and multivariate analysis of variance to analyzing nurse job burnout data, not only ob-tain overall conclusion, and further use of single-variable analysis may also gain comparative results of each dimensions.

Objective To provide applied anatomic data for relevant operations of blood vessels of perisacral promontory(BVPSP). Methods The composition of BVPSP including origin, course, diameter of the middle sacral vessels, the distance between the sacral promontory and the sacral 1 transverse trunk were observed on 37 adult cadavers. Result The BVPSP is composed of the common and internal iliac vessels, the superior segment of the middle sacral vessels and the sacral 1 transverse trunk. Middle sacral artery comes from abdominal aorta. Middle sacral veins are thin walled without valves. The average diameter of middle sacral artery and vein is 1.02 mm and 2.53 mm respectively. The distance between the sacral 1 transverse trunk and the sacral promontory is 5.75 mm. Conclusion The composition of BVPSP, especially middle sacral veins, plentiful vascular anastomosis are the anatomical basis leading to massive hemorrhage in the relevant operations.

AIM: To investigate the expression and significance of MAPK-interacting kinase-2 ( Mnk2 ) and eukaryotic initiation factor 4E ( eIF4E) in the patients with resected esophageal squamous cell carcinoma ( ESCC ). METHODS:The protein expression of Mnk2 and eIF4E in ESCC tissues (98 cases) and normal esophageal tissues (20 cases) were assessed by immunohistochemistry (IHC), and their correlations with clinicopathological features were statisti-cally analyzed.RESULTS:The over-expression rate of Mnk2 and eIF4E was 68.4%(67/98) and 61.2%(60/98), re-spectively.The expression of Mnk2 had a positive correlation with eIF4E (P<0.05).Clinicopathologic analysis showed that Mnk2 expression was significantly correlated with T classification ( P<0.05 ) and clinical stage ( P<0.05 ) .CON-CLUSION:The over-expression of Mnk2 was significantly related to the tumor invasive depth , TNM stages and expression of eIF4E in ESCC.Expression of Mnk2 and eIF4E may have a cooperative formation mechanism in the development of ESCC.

The development of information technology in the medical industry is accelerating the construction of 3-level rehabilitation networks centering on community-based rehabilitation, which is based on the Internet and in combination with the Internet of things(IOT). A municipal rehabilitation hospital cooperated with the health centers of sub-district communities in the city to build a remote rehabilitation network based on IOT technology, for rehabilitation training of community stroke patients. The two sides worked out a cooperation scheme on project management, designed and built a remote community rehabilitation management model. Under the remote monitoring and equipment data IOT, the medical team of the municipal rehabilitation hospital could formulate the therapeutic plan according to the immediately obtained relevant functional evaluation data, and the medical team of the community health service center was responsible for the implementation of the plan. Fifty-three patients in the experimental group received the training of remote lower limb intelligent feedback system based on IOT together with routine rehabilitation training. After 8 weeks of treatment, the functional evaluation data of the two groups were improved in varying degrees( P< 0.05), but the improvement of the experimental group was significantly better than that of the control group( P < 0.05). Remote rehabilitation under the construction path of remote rehabilitation network based on IOT technology could significantly promote the improvement of post-functional rehabilitation of community stroke patients. This study can provide reference for the construction of three-level remote rehabilitation networks based on IOT and the implementation of home-based remote rehabilitation therapy in the future.

Objective :
To compare the inflammatory reaction of peritoneal macrophage after Pg-LPS stimulated in healthy rabbit and hyperlipidemia rabbit.
Methods :
12 New Zealand rabbits were randomly divided into 2 groups with 6 rabbits in each group, and normal diet and high-fat diet were fed to them respectively. The hyperlipidemia model was set up after 6 weeks. The peritoneal macrophage in normal and hyperlipidemia group were isolated and cultured, and then the cells in both groups were respectively divided into 3 groups: control, 1 μg/mL Pg-LPS, and 1 μg/mL E.coli-LPS. After 24 h treatment, the expressions of C-reaction protein (CRP), interleukin-1β (IL-1β), interleukin-6 (IL-6) , interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) were detected by realtime PCR.
Results :
The levels of CRP, IL-1β, IL-6, IL-8, and TNF-α were higher in hyperlipidemia control group than normal control group. The expressions of inflammatory substances were increased after stimulated by Pg-LPS, and statistically higher in hyperlipidemia rabbit group than normal group (P < 0.05).
Conclusion
Pg-LPS can enhance the mRNA expressions of inflammation related factors in peritoneal macrophage in hyperlipidemia rabbit.

OBJECTIVETo explore the primary site and pathological feature of neuroendocrine neoplasm (NEN), especially the NEN of digestive system.
METHODSClinicopathological data of NEN patients at China-Japan Friendship Hospital from January 2012 to December 2016 were retrospectively analyzed. Tumor primary sites were summarized. Association between tumor site and pathological grading in gastroenteropancreatic neuroendocrine neoplasm(GEP-NEN) was examined.
RESULTSThere were a total of 903 cases of NEN. Sites of primary tumor included the digestive system in 699 cases(77.4%), the thorax(including lung, thymus and mediastinum) in 87 cases(9.6%), other sites in 60 cases (6.6%), unknown in 57 cases(6.3%). Among 699 GEP-NEN cases, the primary sites included the stomachin in 207 cases (29.6%), pancreas in 201 (28.8%), rectumin in 185 (26.5%), duodenum in 43(6.2%), jejunum and ileum in 18(2.6%), appendix in 15 (2.1%), gallbladder in 11(1.6%), esophagus in 10(1.4%), and the colon in 9 cases (1.3%). Pathologically, the tumor grading was neuroendocrine tumor (NET) G1 in 336 cases(48.1%), NET G2 in 203 cases (29.0%), neuroendocrine carcinoma (NEC) G3 in 139 cases (19.9%). All the esophagus NEN(10/10), most gallbladder NEN(9/11) and colon NEN(6/9) were poorly-differentiated NEC (G3), while all appendix NEN(15/15), most stomach NEN(147/207, 71.0%), pancreas NEN (156/201, 77.6%), rectum NEN (169/185, 91.4%), duodenum NEN (31/43, 72.1%), jejunum and ileum NEN(16/18, 88.9%) were well-differentiated NET G1 or G2.
CONCLUSIONSThe most common primary site of NEN is the digestive system. The stomach, pancreas and rectum are most common primary sitesof GEP-NEN. Difference in pathological grading is quite greatin different primary sites of GEP-NEN. Most NENs fromesophagus, colon and gallbladder are poorly-differentiated NEC.
