Objective To study the level and influencing factors of sense of coherence (SOC) among elderly patients with Parkinson's disease (PD).Method Totally 118 elderly patients with PD were investigated by a self-designed demographic questionnaire,sense of coherence-13 (SOC-13) and social support rating scale (SSRS),and to explore the level and influencing factors of SOC among the patients.Results The total score of SOC-13 was (52.27±9.30),and it was at a low level.Multiple regression analysis showed that educational level,severity of the disease,family economic status and social support were the influencing factors of SOC.Conclusion SOC of elderly patients with PD is at a low level,which is influenced by individual factors,nurses should take targeted measures to improve the patients' SOC status by the influencing factors.

Objective To investigate the effects of CNTN-1 on the invasion and migration of human esophageal cancer EC9706 cells and the possible mechanism.Methods The expression of CNTN-1 in human esophageal cancer EC9706 cells was measured by qPCR and Western blot.After transfection with CNTN-1 siRNA or CNTN-1, the cells were divided into control group, scrambled siRNA group, CNTN-1 siRNA group, pcDNA3.1-vector group and pcDNA3.1-CNTN-1 group.Cell proliferation, invasion and migration were respectively analyzed by BrdU assay and Transwell test.The expression of MMP-2 and MMP-9 were detected by qPCR and Western blot.Results The mRNA and protein expression of CNTN-1 were significantly upregulated in EC9706 cells.Compared with control, cell proliferation, invasion and migration, as well as the expression of MMP-2 and MMP-9 were significantly decreased by CNTN-1 siRNA, while they were increased by CNTN-1 overexpression (P<0.05).ConclusionsCNTN-1 can influence the invasion and metastasis of esophageal cancer cells through the regulation of the expression of MMP-2 and MMP-9.

Background and purpose: Previous studies have confirmed that the expression of leucine-rich repeat-containing 3B (CLRRC3B) was significantly decreased in different human cancers, which was also associated with the migration and invasion of cancer cells. The aim of this study was to explore the potential mechanism of LRRC3B in the development of esophageal cancer. Methods: The LRRC3B expression was detected in 60 cancer tissues and 60 adjacent non-neoplastic tissues by immunohistochemistry. The mRNA and protein expression of LRRC3B in Eca109 and HEECs were detected using real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR) and Western blot, respectively. Eca109 cells with different treatments were divided into three groups:normal group, negative control group (transfected with pCMV6 plasmid), overexpression LRRC3B group (transfected with pCMV6-LRRC3B plasmid). Transwell assay was used to measure the migration and invasion of Eca109 cells in different groups. The protein levels of E-cadherin, N-cadherin, Vimentin and p-Akt were determined by Western blot. Results: The expression of LRRC3B in esophageal cancer tissues was lower than that of non-cancerous tissues, as well as the expression of LRRC3B in Eca109 was decreased compared with that of normal esophageal epithelial cell line HEEC. Overexpression of LRRC3B significantly inhibited Eca109 cells migration and invasion, upregulated the expression of E-cadherin and decreased the expression of N-cadherin and Vimentin. Moreover, overexpression of LRRC3B significantly inhibited the phosphorylation of Akt in Eca109 cells. Conclusion: The expression of LRRC3B was decreased in esophageal cancer. Overexpression of LRRC3B can efficiently inhibit the EMT progression in esophageal cancer cells by suppressing PI3K/Akt signaling pathway.

Objective To analysis the human T lymphotropic virus (HTLV) infection status in Wenzhou among voluntaty blood donors.Methods Selected 72 417 voluntary blood donors of Wenzhou from from March,1,2016,to November,30,2016,to screen HTLV-Ⅰ / Ⅱ antibody by ELISA method.The positive samples were reexamined two times,two test results of samples were determined positive by ELISA.HTLV positive samples was confiemed by Western Blotting (WB).Results Screened 23 cases of anti-HTLV positive by ELISA method,then confirmed 9 cases of HTLV positive by Western Blotting (WB).HTLV infection rate of Wenzhou blood donors was 0.01％ (9/72 417).Conclusions HTLV infection was found among volunteer blood donors in Wenzhou,but the HTLV infection rate of volunteer blood donors in Wenzhou is still at a relatively low level.

Objective To investigate certain risk factors for and their impact on abnormal liver function in middle-aged and elderly adults.Methods A case-control study was constructed based on the SAGE cohort of 8642 registered residents aged 50 years or over in Shanghai.Of them,137 individuals with abnormal liver function,defined as aspartate transaminase (AST)＞ 40 U/L or alanine aminotransferase (ALT)＞ 40 U/L,were randomly selected as the observation group,while 411 healthy controls were 3 ∶ 1 matched with the cases in the observation group by gender and age (1 year).Face-to-face administered questionnaires and physical examinations were conducted and serum samples were tested for ALT,AST,glucose (GLU),total cholesterol (TC),triglycreide (TG),hepatitis B surface antigen (HbsAg) and anti-hepatitis C virus antibody (anti-HCV Ab).Chi square test and rank sum test were used for single factor analysis,and logistic regression analysis was used for multiple factors.Results The prevalence of HBsAg positive patients was 12.4 ％ (68/548) Univariate analysis showed that hepatitis virus infection and body mass index (BMI) were associated with abnormal liver function (both P＜0.000).Multivariate logistic regression analysis showed that hepatitis virus infection (OR=1.85,95％ CI:1.04 3.29,P-0.036) and obesity (OR=3.60,95％CI:1.92-6.73,P＜0.001) increased the risk of abnormal liver function,whereas chronic medication (OR=0.51,95％ CI:0.32-0.80,P =0.004) decreased the risk of abnormal liver function.Conclusions Among the study population,hepatitis virus infection and obesity are risk factors for abnormal liver function in middle-aged and elderly people.After adjustment for potential confounders,chronic medication is negatively correlated with abnormal liver function and may be a protective factor for liver function.

Objective To extract,isolate and identify the polysaccharide from ginseng,and to investigate its anti-tumor activity in vitro. Methods The ginseng polysaccharide was obtained through water extraction and ethyl alcohol deposition method. Use the Sevage method to remove the protein in the crude polysaccharide. The structural characteristics of the polysaccharide were determined by FT-IR spectra.The RM-1 and HeLa cells were divided into control group and different concentrations (0,50,100,200,300,400 and 500 mg·L-1 )of ginseng polysaccharide groups. The survival rates of the cells in various groups were detected by MTT method. The indirect killing effects of ginseng polysaccharide with different concentrations (0,50,100,200,300,400 and 500 mg·L-1 )on the cancer cells were determined by CTL test. Results The extraction rate of ginseng polysaccharide was 8.7 6% and the structural characteristics demonstrated that the main component of the extract was polysaccharide.The result of MTT showed that there were no significant differences of the survival rates of RM-1 and HeLa cells between different concentrations of ginseng polysaccharide groups after treated for 24 h compared with control group (P>0.05).The result of CTL test showed that the cytototic LHD release rates in different concentrations of ginseng polysaccharide groups were increased significantly (P<0.05)compared with control group;with the increase of ginseng polysaccharide concentration, the cytotoxic LDH release rates were increased firstly and then were decreased.When the concentration of ginseng polysaccharide was 100 mg·L-1 ,the cytotoxic LDH release rate was the biggest.Conclusion Ginseng polysaccharide can indirectly inhibit the growth of the tumor cells by activating T cells and play an anti-tumor effect.
