Objective To understand the correlation between psychological counseling behaviors of accompanying family members and anxiety and depression of inpatients with hepatocellular carcinoma. Methods Used self-designed questionnaires to investigate the behaviors of 45 accompanying family members psychological counseling for their relative hospitalized patients with hepatocellular carcinoma, at the same time, evaluated the anxiety and depression among those 45 hospitalized patients with hepatocellular carcinoma, then analyzed the correlation between the accompanying family members' psychological counseling behaviors and hepatocellular carcinoma in patients' anxiety and depression. Results Among the accompanying family members,53.3%(24/45) were the spouses of the patients. During the accompanying nursing time, there were 20.0%(9/45) accompanying families told to their relative patients less than 2 hours per day, and 80.0%(36/45) told to the patients over 2 hours per day. The proportion of anxiety and depression in the hospitalized patients with hepatocellular carcinoma was 28.9%(13/45) and 77.8% (34/45) respectively. Whether the relationship between the accompanying family members and the patients with hepatocellular carcinoma were spouse relationship was related to the incidence of depression in the patients (χ2=10.470, P=0.005), and whether the time accompanying family members spent in talking with the patients over 2 hours every day was correlative with the incidence of anxiety and depression in the patients (χ2=7.012, P =0.030 andχ2=6.438, P=0.040). The patients who accompanying families told to them less than 2 hours per day suffered a higher depression rate (8/9), and among the patients who accompanying families told to them over 2 hours per day, the lowest rate of anxiety (1/12) was found in the patients who accompanying families told to them around 4.1-6.0 hours per day. Conclusions The patients who are accompanied and cared by their spouses have lower depression rate and lesser depression extent. The accompanying families talk to the patients total 4.1-6.0 hours per day could most favorably reduce the incidence of anxiety and depression in the hospitalized patients with hepatocellular carcinoma.

Objective To discuss the causes of failure of transpedicular screw fixation in treatment of thoracolumbar fractures. Methods A retrospective analysis was done to analyze the failure causes of 24 patients (15 males and 9 females) who received pedicle screw fixation for their thoracolumbar fractures from June 2002 to June 2008 in our department. There were two patients with delayed infection, eight with pedicle screw breakage, one with connecting rod breakage, 10 with internal fixation loosening (including nut loosening) and three with poor screw position. Results All patients received reo-perations including removal of internal fixation plus debridement and lavage in two patients, simple removal of internal fixation in nine patients, removal of inter fixation and posterior fusion in two, replacement of the lengthened fixation plus posterior fusion in nine, and adjustment of the position and orientation of screw in two. All patients were followed up for 6-18 months (average 11 months) , which showed no any complications. Conclusion Improper surgical indication or approach, ineffective fusion, incorrect postoperative rehabilitation exercise, too late removal of the screws and improper surgical operation are main causes for failure of internal fixation.

Objective To compare the effects of rat proinsulin gene therapy via intraportal infusion and intramuscular injection blood glucose level in streptozotocin-induced diabetic rots. Methods (1) Recombinant eukaryotic cell expression plasmid of rat proinsulin gene pCMV/proiusulin was transferred into streptozotocin-induced diabetic rats by intraportal infusion and intramuscular injection to observe the effect of rat proiusulin gene therapy in diabetic rats. The treatment group by intraportal infusion (group A) and the group by intramuscular injection (group C) were given pCMV/proinsulin naked plasmid DNA 100 μg, while the control groups by intraportal infusion (group B) or by intramuscular injection (group D) were treated with similar amount of pCMV DNA. Normal group and diabetes mellitus group were also observed at the same time. (2) Blood glucose level was tested and serum insulin was determined by radioimmunoassay. RT-PCR and immunohistochemistry were used to detemine proinsulin mRNA and protein expressions in liver and skeletal muscle and protein. Results (1) The blood glucose levels in two treated groups were both decreased. In group A, levels of blood sugar decreased about 7 mmol/L and glycemie control was maintained for 3-4 weeks. Serum insulin levels step up significantly after pCMV/proinsulin gene therapy. The blood glucose level in group A was significantly lower than those of group B and DM group (P<0.05), while the serum insulin level was higher than those of two groups (P<0.05). In group C, blood glucose levels decreased about 4 mmol/L and glycemic control was maintained for 1-2 weeks. Meanwhile, the concentrations of insulin increased markedly after gene therapy. The blood glucose in group C was significantly lower than those of group D and DM group (P<0.05), while the serum insulin level was higher than those of two groups (P<0.05). (2) Proinsulin mRNA and protein expressions could be detected in either hepatic cell of group A or skeletal muscle cell of group C, not in group B and group D. Conclusion Proiusulin genetherapy via intraportal infusion or intramuscular injection lowers significantly blood glucose in diabetic rats, and thus offers a potential approach to treatment of diabetes.

Objective:To assess the relationship between serum total bilirubin and fundus arteriosclerosis in different genders.Methods:The physical examination data of Huadong Sanatorium in 2018 were analyzed, and a total of 26 275 people were included in this retrospective cross-sectional study. The age of this study was 18-86 (47.7±11.1) years old. Among them, there were 15 244 males (58.02%) and 11 031 females (41.98%). Participants were divided into 4 groups according to total bilirubin quartile values: Q1<11.50 μmol/L, Q2∶11.50-13.93 μmol/L, Q3∶13.94-17.14 μmol/L and Q4>17.14 μmol/L. The relationship between total serum bilirubin and fundus arteriosclerosis is determined using univariate and multivariate logistic regression analysis methods. The restricted cubic spline method was used to detect the dose-response relationship between total bilirubin and fundus arteriosclerosis. Results:In males, univariate analysis showed that high level of total bilirubin was a protective factor for fundus arteriosclerosis ( OR=0.87, 95% CI 0.78-0.97, P=0.012). After adjusting for other confounding factors, multivariate analysis showed that high level of total bilirubin remained as an independent protective factor for fundus arteriosclerosis ( OR=0.86, 95% CI 0.74-0.99, P=0.047). There was a linear dose-response relationship between total bilirubin level and fundus arteriosclerosis ( P=0.012). In females, univariate analysis showed that there were no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.96, 95% CI 0.80-1.17, P=0.709). After adjusting for other confounding factors, multivariate analysis showed no statistically significant association between high level of total bilirubin and fundus arteriosclerosis ( OR=0.98, 95% CI 0.76-1.27, P=0.888). No linear dose-response relationship between total bilirubin level and fundus arteriosclerosis was found in females ( P=0.253). Conclusion:There are gender differences in the relationship between total bilirubin and fundus arteriosclerosis in this cohort. Elevated levels of total bilirubin are associated with fundus arteriosclerosis in males but not in females.
