Objective To investigate the situation of family intimacy and adaptability, and social avoidance and distress in severe burn patients, and explore the correlation between them, so as to provide basis for intervention. Methods From January, 2013 to June, 2015, 289 patients with severe burn were surveyed with self-designed general condition questionnaire, Family Adaptability and Cohesion Evaluation Scale (FACES Ⅱ) and Social Avoidance and Distress Scale (SADS), and analyed with Pearson correlation analysis. Results The real family intimacy and adaptability were lower in the severe burn patients than in national norm (t>3.830, P<0.01), and the ideal family intimacy, dis-satisfied intimacy level, ideal adaptability and dissatisfied adaptability level were higher in the severe burn patients than in national norm (t>3.857, P<0.01). The SADS score was higher in the severe burn patients than in national norm. The real intimacy, real adaptability and the to-tal score of FACES II negatively correlated with the scores of SADS (P<0.05), while the levels of dissatisfied intimacy and adaptability posi-tively correlated (P<0.05). Conclusion The social avoidance and distress exist in severe burn patients, which may associated with the family intimacy and adaptability, that some interventions may target to.

Objective To observe the effect of Wnt/β-catenin pathway on proliferation of human umbilical vein endothelial cell (HUVEC) using the glycogen synthase kinase 3β (GSK-3β)-targeting RNAi recombinant adenovirus vector. Methods Homologous recombination and cloning techniques were used to construct RNAi recombinant adenoviral expressive vectors specific to GSK-3β. Then, the adenovirus plasmids was transfected into HEK 293A cells to produce adenovirus and amplify the adenoviral stock. Plaque forming assay was used to titer the adenoviral stock. The GSK-3β and β-catenin protein expressions were detected by Western blot and immunohistochemistry. The proliferation of HUVEC was detected with MTr assay. Results The RNAi adenovirus vectors specific to GSK-3β were successfully produced with high titer. The expression of GSK-3β protein in HUVEC could be down-regulated efficiently by the RNAi adenovirus, along with increased β-catenin protein expression. The proliferation of HUVEC was significantly increased (P < 0.05 or P < 0.01) after infected with GSK-3β RNAi recombinant adenovirus for 3, 5, 7 days. Conclusion RNAi adenovirus is an important tool that can inhibit the expression of GSK-3β efficiently, along with increased β-catenin protein expression. Up-regulating of the Wnt/β-catenin pathway might play an important role in the proliferation of HUVEC.

Objective To investigate the effect of Helicobacter pylori (Hp) infection on plasma lpid and high sensitive C reactive protein (hs-CRP) levels in patients with cerebral infarction, and explore the pathogenesy. Methods Seventy-nine cerebral infarction patients without nearly inflammatory reaction disease were recruited. Hp was detected by breath test,the patients were divided into infection-negative group (15 cases), light infection group (29 cases) and severe infection group(35 cases) according to the results,the last two groups were as infection-positive group. The plasma lipid and hs-CRP levels were exanined.Results Compared with infection-negative group,the total cholesterol,low density lipoprotein,hs-CRP levels increased obviously in infecton-positive group (P ＜ 0.05). The level of hs-CRP in severe infection group was higher than that in light infection group [(10.21 ±4.98) mg/L vs. (5.81 ±4.21) mg/L](P=0.001 ). Conclusions Hp infection may increase vascular inflammatory reaction through lipid metabolic disturbance. The cerebral infarction with higher Hp infection, and with the degree of infection increased, the risk is also increased accordingly.
