BACKGROUND: Insulin-like growth factor-1 (IGF-1) has important biological effects on the heart, it can promote cardiac and vascular smooth muscle growth and metabolism.OBJECTIVE: To summarize the biological effects of IGF-1, to clarify the mechanism of exercise-induced cardiac hypertrophy, and make better use of the exercise influence on IGF1 to achieve adaptive cardiac hypertrophy.METHODS: With exercise-induced cardiac hypertrophy, insulin-like growth factor, exercise in English for the search terms,Pubmed database from January 1990 to April 2009 was retrieved; With exercise-induced cardiac hypertrophy, insulin-like growth factor, exercise in Chinese for the search terms, CNKI database from January 1990 to April 2009 was searched. Literatures were limited to English and Chinese languages. Inclusive criteria: animal experimental study and clinical application research closely linked to IGF-1; exclusive criteria: the old literatures and Meta analysis.RESULTS AND CONCLUSION: Totally 41 literatures were screened out by computers, according to the inclusion and exclusion criteria; 31 documents of which were involved for analysis. The IGF coordinates with other growth factors to promote differentiations and maturity of a variety of cells. The current data indicate that the blood serum and the cardiac local IGF-1 play an important role on cardiac hypertrophy. This study used the method of literature to analyze the production and action mechanism of the circulatory and cardiac IGF, discuss the functions of cardiac local IGF and the effect of exercise on it, and bring forward that exercise can alter the IGF expressions, IGF is related to the formation of exercise-induced cardiac hypertrophy.

Objective To explore the influence of lifestyle intervention on obesity and diet behavior in children with simple obesity.Methods 80 simple obesity children were chosen as research subjects,the parents were given cognitive behavior intervention,the children were given lifestyle interventions to control weight.The changes of obesity degree and dietary behavior were observed after the interventions.Results After the intervention,the parents in the adjustment of dietary structure,limit the time of watching TV,limit of snack in.take were significantly higher than those before intervention(P ＜ 0.05).Children reduced meat,snack intake,watch TV time more than those before intervention(P ＜ 0.05).Obesity degree was significantly lower than that before intervention(P ＜ 0.05).Conclusion The lifestyle intervention is beneficial to change unhealthy life style in obese children,and to reduce weight.

Objective To investigate the correlation between Gab2 expression and platinum drugs chemotherapy resistance by detecting the expression of Gab2 in ovarian cancer.Methods Immunohistochemical and Western blotting techniques were used to detect the expression of Gab2 in 107 specimens of serous ovarian tumor tissue and 12 specimens of normal ovarian tissues resected during bladder cancer radical operation in the department of gynaecology of our hospital from January 2011 to June 2015.The correlation between Gab2 expression with clinical stage and effect of combined chemotherapy based on platinum drugs was analyzed.Results The Gab2 expression level in ovarian cancer tissue was significantly higher than that in normal ovarian tissue,moreover had a relation with the FIGO clinical stage,the expression level of Gab2 increased with the increase of clinical stage,the difference was statistically significant (P<0.05);61 cases were sensitive to chemotherapy,46 cases were resistant to chemotherapy,the Gab2 expression level in the patients with chemotherapy resistance was significantly higher than that in the patients with chemotherapy sensitivity,the difference was statistically significant (P<0.05).Conclusion Gab2 may become one of effective indexes for predicting platinum drugs chemotherapy sensitivity.

Objective To study the influence of blood glucose, blood lipids and other cerebral infarction risk factors in the mean platelet volume (MPV). Methods A total of 562 patients with cerebral infarction and type 2 diabetes mellitus (DM) and 216 cerebral infarction patients without DM (non-DM) were included in this study. The platelet parameter of peripheral blood and other laboratory indexes were detected including platelet count (PLT), MPV, platelet distribution width (PDW), plateletcrit (PCT), fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL-C), low density lipoprotein (LDL-C) and very low density lipoprotein (VLDL-C), urea nitrogen (BUN), creatinine (Cr), uric acid (UA), high-sensitivity C-reactive protein (hs-CRP) and homocysteine (HCY). The patients were scored by the National Institute of Health stroke scale (NIHSS) after hospitalization. The MPV changes in patients with cerebral infarction were observed, and different influences of blood glucose, blood lipids to MPV were analysed. Results Values of FBG, HbA1c, TC, TG, LDL-C, BUN, UA, HCY, hs-CRP, and NIHSS were significantly higher in DM group than those of non-DM group. The score of NIHSS was significantly higher in DM group than that of non-DM group. The level of HDL-C was significantly lower in DM group than that of non-DM grou. The MPV was significantly higher in DM group than that of non-DM group [(9.60 ± 1.35) fL vs. (9.27 ± 1.01) fL, P<0.05). There was a positive correlation between MPV and FBG, HbA1c, hs-CRP, WBC, VLDL-C and NIHSS, r=0.438, 0.410, 0.336, 0.164, 0.321 and 0.249 (P<0.05). Multiple regression analysis showed that FBG, VLDL-C, HbA1c, hs-CRP and NIHSS were the independent influential factors of MPV (P<0.05). Conclusion The influencing factors of MPV should be controlled in patients with cerebral infarction combined with type 2 diabetes mellitus, reducing the activation of platelet, and delaying the progress of cerebral infarction.

Objective To explore the clinical effect of electrochemical therapy (EchT) on hemangiomas of liver.Method 186 cases of hemangiomas of liver with,male 97 and female 89 were selected for the study.The age ranged from 31～55 years old.The electrochemical therapy instrument of model ZAY-B and the electrode made of platinum were used.Suitable manipulating technique and treating quantity of electricity were investigated for the patients.Electrodes were inserted into the tumor through a tracer directly by opening the abdominal cavity.Normal tissue of liver was protected by the spaghetti and the electrodes were connected to EchT device,then the treatment began.The therapeutic voltage was 6～8V,electic current 120～160mA.The quantity of electricity was 100～150 Coulombs per 1.0cm diameter of the tumor.The treatment could be terminated when the tumor became from soft to stiff.Result The therapeutic efficacy was evaluated 6 months after EchT.Through the follow-up of 1～5 years,103 of total 186 cases of hemangiomas of liver completely disappeared(72.5%);31 cases partially relieved (21.8%) and 8 cases were ineffective (5.6%).Conclusion EchT to treat hemangiomas of liver is safe and efficacy,with less traumatic and a quick recovery.It can be served as a new method for treating hemangiomas of liver.
