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 investigate the characteristics of the clinic manifestations and the electromyogram changes in patients with chronic N2hexane intoxication. Methods The clinic manifestations, the electromyography and nerve conduction velocities were analyzed in 9 patients with N2hexane intoxi2 cation. Results The main clinical manifestations of the disease were acroparesthesia and asthenia, especially in legs. The abnormality rate of electromyography in patients with N2hexane intoxication was 100%. The conduction velocity of the sensory nerve and the motor nerve decreased at a rate of 33.33% and 88.89% respectively. The distal latencies were prolonged( 100% ). The denervated electromyogram was 33.33%. Conclusion The main clinical manifestations of the disease were Peripheral neuropathy. The chronic N2hexane intoxication mainly led to the imparement, especially in the distal region of the motor nerve in legs,and the damages of the nerve could be related to the duration of exposure to N2hexane.

Objective To analyse the differences between idiopathic and symptomatic childhood epilepsy with occipital patoxysms. Methods The medical records of 38 patients with interictal spikes and/or sharp waves over occipital areas,posterior temporal-parietal areas,or both were retrospectively analysed.Epidemiological data,ictal symptoms,electroencephalogram,neuroimaging studies,treatment response and prognosis were compared using chi-square test or Mann-Whitney U test. Results Four patients of idiopathic group had positive family history related to nervous system.Seizures were more frequent in symptomatic group than in idiopathic group.Both groups showed autonomic symptoms,while ictal vomiting and deviation of eyes were more common in the presence of Panayiotopoulos type.The prognosis of idiopathic group was much better than that of symptomatic group. Conclusion Panayiotopoulos syndrome is more common.Neurologic deficits and electroencephalographic characteristics are major factors to predict seizure remission in children with occipital lobe epilepsy.Idiopathic childhood epilepsy with occipital paroxysms may result in better prognosis.

Chronic obstructive pulmonary disease ( COPD) is a group of chronic airway inflammatory disease characterized by sustained airflow limitation and pulmonary function damage.Inflammation and tissue repair repeatedly result in airway remodeling.Now the mechanisms of airway remodeling remain unclear.More and more researches indicated that epithelial mesenchymal transition ( EMT) is crucial in the airway remodeling of COPD.EMT could be induced by various cell factors and signal channels in the airway epithelium, thus the airway remodeling happened.This review systematically introduces EMT and focuses on the relationship of EMT and airway remodeling of COPD and the probable mechanisms.

Objective To investigate the inter-arm invasive blood pressure differences during hip replacement in patients with lateral position and its relationship with position.Methods Sixty-six patients having underwent hip replacement in orthopedic surgery with lateral position were enrolled.Invasive blood pressure measurements were obtained from bilateral radial artery in all patients every 5 minutes.Simultaneously bilateral invasive blood pressure measurements were obtained and compared.Results At supine position,systolic pressure,diastolic pressure and mean arterial pressure of the uninjured side were (128.16 ±20.09),(69.47 ± 8.64) and (89.03 ± 10.42) mmHg (1 mmHg =0.133 kPa);systolic pressure,diastolic pressure and mean arterial pressure of the injured side were (127.90 ± 20.44),(69.86 ± 8.81) and (89.21 ± 10.71) mmHg.There was statistical difference in inter-arm diastolic pressure (P ＜ 0.05),but inter-arm systolic pressure and mean arterial pressure had no statistical differences (P ＞ 0.05).At left-lateral position,systolic pressure,diastolic pressure and mean arterial pressure of the uninjured side were (129.12 ± 21.93),(69.23 ± 8.92) and (89.19 ± 11.35) mmHg;systolic pressure,diastolic pressure and mean arterial pressure of the injured side were (129.01 ± 21.72),(69.51 ± 9.02) and (89.34 ± 11.35) mmHg.There was statistical difference in inter-arm diastolic pressure (P ＜ 0.05),but inter-arm systolic pressure and mean arterial pressure had no statistical differences (P ＞ 0.05).At right-lateral position,systolic pressure,diastolic pressure and mean arterial pressure of the uninjured side were (128.78 ± 20.34),(69.54 ± 9.06) and (89.29 ± 10.82) mmHg;systolic pressure,diastolic pressure and mean arterial pressure of the injured side were (128.27 ± 20.56),(70.00 ± 9.09) and (89.43 ± 10.89) mmHg.There were statistical differences in inter-arm systolic pressure and diastolic pressure (P ＜ 0.05),but inter-arm mean arterial pressure had no statistical difference (P ＞ 0.05).The bilateral radial artery blood pressure difference under different positions was ＜ 1 mmHg,and had no clinical practical significance.There was no correlation between blood pressure and age,sex,body mass index.Conclusion Bilateral radial artery in the same patients with invasive blood pressure has no clinical difference,and patients with lateral position operation for radial artery puncture pressure need not consider the differences of blood pressure between arms.

BACKGROUND:The increase of serum cholesterol levels is positively correlated with the increasing incidence of osteoarthritis. Little is known about the role of high-fat diet in the degeneration of articular cartilage and induced arthritis.
OBJECTIVE:To observe the morphology change of the articular cartilage of New Zealand rabbits after high-fat diet, and explore the role of food in the articular cartilage degeneration.
METHODS:Forty New Zealand white rabbits were randomly divided into two groups. In control group, rabbits were fed with basal diet. In high-fat diet group, rabbits were fed with high-fat diet (20%lard and 80%basal diet). Fasting blood samples was taken every 4 weeks, to detect the triglyceride and total cholesterol levels. After rabbit were fed for 28 weeks, the knee joint was grossly observed and the femoral condyle cartilage was scanned by scanning electron microscope.
RESULTS AND CONCLUSION:Compared with the control group, the triglyceride and total cholesterol levels were significantly increased in the high fat group (P<0.05). Under scanning electron microscope, the high-fat group showed rough surface of condylar cartilage, shal ow pouch, messy arrangement, irregular shape and uneven size. The surface of cartilage exhibited focal denudation, irregular arrangement, uneven porosity and fractured cavity. Under higher magnification, smal mountain-like structure of cartilage surface became shal ow and flattened, the pores disappeared. Long-term high-fat diet may induce and aggravate cartilage damage, suggesting it may be involved in the pathogenesis of osteoarthritis.
