Objective To detect the Bag-1 and VEGF expressions in HCC tissues,cancerous liver tissues and normal liver tissues,and to explore their relationship with prognosis.Methods Immunohistochemical staining (SP method) was used to detect Bag-1 and VEGF in 60 cases of hepatocellular carcinoma specimens,next to the 30 cases of hepatocellular carcinoma in liver tissue,and 14 cases of normal liver tissue specimens,and their clinicopathological features were analyzed.Results Bag-l,VEGF expression rates were highest in HCC tissues [80.0 ％ (48/60),73.3 ％ (44/60)] and with adjacent tissues [46.7 ％ (14/30),43.3 ％ (13/30)],normal liver tissue [28.6 ％ (4/14),21.4 ％ (3/14)] expression rates had differences (P ＜ 0.05).Bag-1,VEGF expression had relationship with liver cancer staging,lymph node metastasis,tumor thrombosis formation,the correlation between the presence or absence of capsule formation (P ＜ 0.05),while had no relationship with the patient gender,age,tumor grade,tumor size,and alpha-fetoprotein (AFP) and other factors correlation (P ＞ 0.05).Bag-1 and VEGF expression in HCC specimens positive 40 cases,while negative eight cases,both in HCC tissues expression was positively correlated (P ＜ 0.05).Bag-1,VEGF positive expression in patients 1-year,2-year survival rates were less than negative patients,the survival time of patients with positive group was significantly lower than the negative patients (P ＜ 0.05).Conclusion Bag-1 and VEGF expressions are closely related with biological characteristics of liver cancer,and which is closely related to the prognosis of patients with hepatocellular.

Objective To explore the influence of nursing intervention on the pocket infection and other related problems following CRT-D therapy in chronic heart failure patients.Methods The causes of pocket machinery burst and skin incision dehiscence,pocket bleeding or hematoma and pocket infection following CRT-D therapy from March 2008 to March 2011 were reviewed,then analyzing and summarizing them to work out a detailed nursing interventions plan.During April 2011 to June 2013,nurses carried out the nursing intervention on patients who accepted CRT-D implantation.At last we compared the occurrence of pocket machinery burst and skin incision dehiscence,pocket bleeding or hematoma and pocket infection during the period of 6 months after CRT-D therapy between the two groups.Results After the implementation of nursing interventions,the incidence of pocket infection and other related problems following CRT-D therapy in chronic heart failure patients reduced significantly.Conclusions The interventions such as rigorous preoperative skin preparation,eliminating the potential factors of infection,intraoperative strict aseptic operation,choosing the appropriate position of pocket,the implementation of interventions to prevent bleeding,meticulous and rigorous postoperative nursing,providing healthy knowledge sufciently and strengthening follow-up,finding problems and solving them timely can prevent the pocket machinery burst and skin incision dehiscence,pocket bleeding or hematoma and pocket infection following CRT-D therapy effectively.

Objective To investigate the protective effects of ethanol-extract of Halenia elliptica D. Don on chemical hepatic injury in mice. Methods Mouse models of chemical hepatic injury were induced by intraperitoneal injection of 0.12 %CCL4. Extract of Halenia elliptica D. Don by alcohol was administered,and serum ALT,AST activities and liver glycogen level were measured in mice. Results Compared with the models,the enzyme activities of ALT and AST were significantly reduced and the content of liver glycogen was significantly increased in the ethanol-ex tract of Halenia elliptica groups. Conclusion It is indicated that ethanol-extract of Halenia elliptica D. Don has an effect in protecting the liver.

Objective To investigate the changes of microarchitecture and gene expression of subchondral bone in the initial stage of traumatic arthritis ,to explore the characteristics of subchondral bone remodeling and its role in the articular cartilage de‐generation .Methods The medial meniscal tear (MMT) was performed on the right knees of 13 SD rats to simulate the traumatic osteoarthritis ,while sham operation on the control group .Three weeks later ,all the rats were executed and dissected ,with proximal tibiae being kept and distributed into the two groups ,10 respectively .Micro‐computed tomography (micro‐CT) was adopted to re‐construct and analyze the subchondral bone .After being fixed by 4% paraformaldehyde ,all the samples were decalcified until six weeks passed ,followed by paraffin‐sectioning ,safranin O and fast green staining ,and examining and photographing under an ordina‐ry optical microscope .The RNA of another 3 SD rats′subchondral bone was extracted ,and a real‐time PCR test was carried out to illuminate the expression variation of bone‐formation marker genes (ALP ,RUNX2 ,and OCN) ,and bone‐resorption marker genes (TRAP ,CTSK and MMP9) ,between the two groups .Results Three weeks after MMT surgery ,subchondral bone disorders were observed among the experimental samples through micro‐CT scanning .There was lesser BV/TV ,Conn .D and Tb .Th(P<0 .05) and more Tb .Sp(P<0 .05) in the experimental group compared with the control group .In the pathological section ,arthritic degen‐eration was not spotted in both groups ,but trabeculae of the experimental group were found to be sparse .Compared with control group ,the level of mRNA expression of the bone‐formation marker genes of the experimental group was decreased(P<0 .05) ,while bone‐resorption related genes increased(P<0 .05) .Conclusion The model of initial traumatic osteoarthritis induced by MMT in rats′knees showed an active bone remodeling ,more bone absorbing than bone formation ,lowered bone volume ,and microarchitec‐ture changing of the subchondral bone .

Objective: To investigate the effect of recombinant human growth hormone(rhGH) in the treatment of liver cirrhosis with hypoproteinemia. Methods: 28 patients with liver cirrhosis,whose albumin level was below 35 g/L,were randomly divided into two groups:rhGH treatment group and control group.Serum albumin,ALT and other items were measured 30,60 and 90 days after the start of treatment. Results: After 30 days,an increase in plasma albumin was observed in the two groups,but the change in the treatment group was more obvious than that in control group,An increase in plasma protein in treatment group and the decrease in control group were observed with significant difference between groups. Conclusion: Recombinant human growth hormone can increase the level of ambumin in liver cirrhosis patients and improve the function of liver.

Objectives:To observe growth suppressive effects of human wild type p53(wt p53) gene on human esophageal cancer cell line. Methods:Using the retroviral vector to introduce exogenous wt p53 gene into human esophageal cancer cell line ECA109,the gene expression and tumor inhibition were studied in vitro and in vivo . Results:The expression of p53 in transfected cell lines(ECA 109/p53 ) was increased.The growth rates and the ability to form colony in soft agar were greatly inhibited in ECA 109/p53 cells versus ECA109/neo and ECA109 cells.The G 0+G 1 ratio increased and S ratio decreased in cell cycle distribution,and apoptosis index significantly rose in the ECA109/p53 cells,which were confirmed by FCM analyzing.The tumorigen icity of ECA109/p53 cells in nude mice was obviously suppressed by exogenous p53. Conclusions:Exogenous wt p53 mediated by retroviral vector could inhibit the growth of human esophageal cancer cell.

Child safety seats have been proven to be one of the most effective tools for protecting child passengers. However, the widespread phenomenon of safety seats being "unavailable," "owned but not used," or "used incorrectly" is prevalent globally. This paper aims to summarize the obstacles to the use of child safety seats from four aspects: Individual, society, environment and policy, in order to provide a basis for follow-up comprehensive intervention to ensure the safety of children.
