Studies show that some Trim family proteins are associated with tumorigenesis and cancer progression.Trim members are differently expressed in various cancers including lung cancer,hepatocellular carcinoma,colon cancer,stomach cancer and breast cancer.Trim proteins are found to be involved in tumor progess by modulating the expression of tumor associated genes via several signaling pathways such as p53 and NF-κB pathway.Members of Trim family can be used as oncogenes or anti-oncogenes in the biological processes such as tumor cell proliferation,cell differentiation,cell apoptosis and metastasis.

Objective The purpose of this study was to identify the effect factors on family adaptation of hospitalized children.Methods A survey was conducted in 330 hospitalized children's parents using questionnaires such as FSI,FVI,FHI,FWBI.Results Multiple factor analysis showed that the strongest resilience factor was family hardiness,the second one was general family value on family adaptation of hospitalized children.Conclusions Family hardiness and family value have the adjusting role on family adaptation of hospitalized children.Therefore,the significance of this study can be used to develop family nursing intervention program based on family resilience to strengthen family adaptation of hospitalized children.

Objective To explore the expression of Survivin and MHC in non-small cell lung cancer (NSCLC), and their interaction.Methods A total of 40 patients with histologically diagnosed NSCLC were enrolled in this study.Control samples were consisted of normal lung tissues from 15 patients.Expression of Survivin and MHC were detected by flow cytometry in 40 non-small cell lung cancer tissues and 15 normal lung tissues.Results The positive rates of Survivin protein expression in NSCLC tissues classified stages Ⅰ,Ⅱ and Ⅲ were 28.57% ,30.77% and 80.00% respectively.There was a correlation between Survivin protein expres-sion and stages of NSCLC.Survivin protein expression was detected in 19 of 29 patients with lymph node metas-tasis, and 3 of 11 patients with no metastasis.There was a statistically significant difference between the two groups (P<0.030).The loss expression rates of MHC-Ⅰ in NSCLC tissues of low grade,intermediate grade and high grade were 84.62% ,42.10% and 37.50% respectively.There was a correlation in expression be-tween MHC-Ⅰ and tumor grade.The positive rates of MHC-Ⅱ expression in NSCLC tissues was related to pa-thology type (P=0.005).The expression in squamous cancer and non-squamous non-adno cancer was lower than that of adenocarcinoma (P=0.002, P=0.04).There was no obvious correlation between the expression of Survivin and MHC-Ⅰ,MHC-Ⅱ in NSCLC.Conclution The expression of Survivin and MHC could be in-volved in the pathogenesis and development of NSCLC, and the combined detection will predict the prognosis of the patients with NSCLC.

Objective To investigate the patterns for the recurrent and metastatic gastric cancer after curative resection and to indicate the strategy of treatment. Methods 162 patients who had received radical resection and presented post-operation failure during recent 9 years were analyzed. The failure patterns were confirmed by type-B ultrasonic or CT / MRI imaging. 15 of 34 patients with abdominal dropsy were diagnosed by adenocarcinoma cells in the abdominal dropsy. All superficial lymphadens and abdominal wall metastasis were diagnosed via punctuation. 31 patients with gastric remnant and (or) anastomoses recurrence were diagnosed via biopsy. Results Of 162 patients, 63 presented the recurrence or metastasis in multiple sites,including abdominal lymph node (LN) metastases in 46.9 % (76/162), peritoneum metastases in 21.0 % (34/162),gastric remnant and (or) anastomoses recurrence in 19.1% (31/162), liver metastases in 19.1% (31/162), the incidence rates of other parts were all ＜10 %. Meanwhile, out of 76 patients with abdominal lymph node metastases, 48.7 % (37/76) patients with peri-gastric LNs metastases, 31.6 % (24/76) with peri-pancreatic LNs metastases, 19.7 % (15/76) with para-aortic LNs metastases. The incidence of LN metastases was 57.7 % (56/97) in cancer arising from gastric fundus/cardia and 60.4% (29/48) in gastric body and 64.7 % (11/17) in pylorus antrum. Conclusion The regional failure sites for gastric cancer patients with radical resection were dominantly found in the gastric stump/stoma, the peritoneum and pelvic cavity implantation and abdominal cavity LN metastases, especially in the peri-gastric, peri-pancreatic and/or para-aortic LN metastases. The distant place failure sites were mainly in the liver, lung, brain, spondylus, cervical part LN and mediastinal LN metastases. Therefore, we should take chemotherapy, abdominal cavity chemotherapy and regional radiotherapy to prevent the regional district recurrences and distant metastasis after the gastric cancer patients with radical resection. Radiotherapy fields should focus on the gastric stump/stoma and the peri-gastric, peri-pancreatic and para-aortic LN regions.

Objective:To investigate the relationship between different obesity phenotypes and abnormal blood pressure in children and adolescents in Yinchuan city, and to provide appropriate treatment and intervention measures for obese children and adolescents.Methods:The current research design was adopted to facilitate the cluster sampling.A total of 1 047 children and adolescents aged 12 to 18 in Yinchuan were enrolled in this study from September 2017 to September 2018.There were 530 males and 517 females, with an average age of (13.93±1.24) years old.The questionnaire survey, physical examination and laboratory testing were carried out.Statistical analysis was performed by using SPSS 19.0 software.Results:Among the children and adolescents with normal weight, the composition ratio of the metabolically unhealthy normal-weight (MUNW) phenotype was 7.6%.In the obese cases, the composition ratio of the metabolically healthy obesity (MHO) phenotype was 20.2%.The blood pressure of MUNW [systolic pressure SBP: (119±13) mmHg(1 mmHg=0.133 kPa); diastolic pressure(DBP)(74±10) mmHg] and metabolically unhealthy obesity (MUO) [SBP (127±10) mmHg; DBP(74±7) mmHg] phenotypes were significantly higher than those of the metabolically healthy normal-weight (MHNW) phenotype (all P<0.05). The blood pressure of the MUO [SBP(127±10) mmHg; DBP(74±7) mmHg] phenotype was significantly higher than that of the MHO phenotype ( P<0.05). After adjusting for age, gender, and family history of hypertension, MUNW and MUO phenotypes were 5.93 (95% CI: 3.10-11.36) and 11.63 (95% CI: 6.37-21.24) times more likely to develop blood pressure abnormalities than MHNW phenotypes, respectively ( P<0.001). The MHO phenotype was 0.63 (95% CI: 0.08-4.93) times more likely to develop blood pressure abnormalities than the MHNW phenotype ( P=0.66). Conclusions:The MHO phenotype does not increase the risk of abnormal blood pressure, while the MUNW phenotype does.Therefore, it is recommended to identify the MHO phenotype and MUNW phenotype in order to provide appropriate obesity treatment and interventions for children and adolescents.

Objective To assess the effects of orthotopic liver transplantation (OLT) on the quality of life (QoL) of the patients with end stage liver disease. Methods QoL of OLT recipients was assessed by the GLQI index of the digestive system disease. A total of 43 recipients with benign end stage liver disease without operational complications, who were clearly conscious and had no difficulty in comprehending the investigation table because of their relative good education above the middle school, had been investigated during May 2000 to December 2002. The detecting data were divided into three parts including before OLT, at discharge, and 3 months after discharge. Results At the stage of discharge, QoL of OLT recipients was improved as compared with that before OLT. The physical function, psychological status, symptom of the recipients had been significantly improved than as compared with those before OLT ( P 0.05). And at the stage of 3 months after discharge, QoL of the recipients was improved significantly than that in the hospital ( P
