Objective: To explore children's self-concept differences in age,sex and area during early adolescence.Methods: 533 children aged from 8 to 13 years were surveyed with the Piers-Harris Children's Self-Concept Scale.Results: ①Children's self-concept as well as its six components developed unequally as age grew.Significant differences existed in the Intellectual and School Status Subscale and the Physical Appearance and Attributes Subscale among children of different ages.②Girls did significantly better than boys in Behavior,Intellectual and School Status and Popularity subscales.③Children in urban areas scored significantly higher than those from the countryside in Physical Appearance and Attributes Subscale.Conclusion: There is certain uniqueness in children's general self-concept as well as its different components,according to children's ages,sexes and areas during early adolescence.

Apolipoprotein E is an important regulation factor in lipids metabolism. It has been accepted that apolipoprotein E is relevant to many diseases such as Alzheimer′s disease and coronary heart diseases. And increasing study has revealed that apoE gene polymorphism is associated with some kidney diseases. We reviewed the progress of influences of apoE gene polymorphism on renal diseases.

Objective To study the efficacy and adverse reactions of the treatment on different types of infantile hemangiomas (IH) with different doses of propranolol .Methods One hundred and fifty cases of IH without contraindications were randomly treated with different doses of propranolol (low dose group:1 mg?kg -1 ?d-1 ;high dose group:2 mg?kg -1 ?d-1 ) under ECG monitoring inferior half an hour to breastfeeding taking ,and stay in hospital for observation for 6 to 24 hours after the treatment . The patients returned to the hospital for review every month(ECG and blood RT ;lung function in necessary) .Results The curative effect is better on strawberry IH than that on flat IH ,also better on deeply IH than that on superficial IH .The adverse reactions oc‐curred relatively slight in the low dose group and there was no significantly statistical differences on the treatment effects between the both groups(P>0 .05) .Conclusion It is safe and effective to treat IH with propranolol .

Objective To explore a novel improved method of simplified fluid-supplement therapy during the diuresis stage after renal transplantation.Method We adopted an improved fluid-supplement therapy to treat 26 postoperative patients of heterologous kidney transplantation after returning Liger's liquid, 500ml of 5% glucose-salt liquid, and 500ml liger's Compound back to linical wards by means of replenishing 500ml of sodium lactate sodium chloride injection in turn for fluid supplement. In addition, the patients were given originally 10～20ml of 10% calcium glubionate within 12 hours after their operations. Results Based on the results of both blood and urine determination at the first day aftert kidney transplantation, we discovered 2 patients slightly decreased sodium in blood, one displayed hypokalemia,2 patients showed slightly hyperkalemia value than normal referance level. Meanwhile, all patients manifested blood chlorate value between 101?4. Besides, another 7 patients had slightly increased blood suger value. However, no hypernatremia, hypocalcia or hypomagnesemia were found. As a result, all specific gravity ratio value were from 1.010 to 1.015 aparting from hemobilinuria existed in some patients. Conclusion The succesessful use of the new fluid-supplement therapy could effectively avoid unnecessary repeated haemospasia analysis for mornitoring and adjusting the balance of electrolyte, which could remarkably simplify and faciliate the postoperative management of renal transplantation.

Continuous ambulatory peritoneal dialysis (CAPD) is an important form in integrated renal replace treatment.Malnutrition is still a problem to be resolved in CAPD. A number of investigations showed the effects of amino aicd peritoneal dialysate in malnutrition CAPD patients had benefit effects on improving nutrition status.The results of clinical progress of amino acid peritoneal dialysate used in peritoneal dialysis were reviewed.

Objective To prepare the Polyporus umbellatus polysaccharides (PUPS) long cirrculating liposomes (LCLs) and to study the quality control of PUPS LCLs. Methods The PUPS LCLs were prepared by chloroform infusion combined with the ammonium sulphate gradient method. The content and encapsulation efficiency of PUPS in LCLs were determined by UV-Sephadex method. Results Mean diameter of the PUPS LCLs was 100 nm, with the encapsulation efficiency of 55.3%. Conclusion The LCLs with high encapsulation efficiency and small particle size could be prepared by chloroform infusion combined with the ammonium sulphate gradient method. UV-Sephadex method is suitable for the quality control of PUPS LCLs and the results are reliable.

Aim To study effects of rhomotoxin (Rh) on electrophysiologic parameters in rabbit heart. Methods The rabbit hearts in vivo were injected with Rh 12.5 ?g?kg-1 , 25 ?g?kg-1 or saline iv respectively and the isolated rabbit hearts were perfused by Krebs-Henseleit(K-H) perfusion liquid containing Rh 0.34 ?mol?L-1 or 0.68 ?mol?L-1. The electrophysiologic parameters were observed before and after drug adminitration.Results At 20,40,60 and 80 min after injection of Rh 12.5 ?g?kg-1 iv,the VDT,ERP and RRP had no significant changes; but at 20,40,60 and 80 min after injection of Rh 25 ?g?kg-1 iv a significant prolongation of ERP and (or) RRP was found (P

The review is focused on the development and recent research of the first tissue-specific angiogenic molecule,endocrine gland-derived vascular endothelial growth factor(EG-VEGF).It has been found that EG-VEGF only targeted on steroidgenic endocrine organs or cells through G-protein coupled receptor,the phosphorylation of G-protein coupled receptor could activate mitogen-activated protein kinase p44/42 and phosphatidylinositol-3 kinase(PI3K) pathways signal transdution.There are many reports that believes MAPK and PI3K is involved in the regulation of proliferation,migration,survival of endothelial cells and tumor angiogenesis,so EG-VEGF may serve as a potential target for antiangiogenic therapy of cancer in the future.
