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.

Objective To compare the influences of different routes of nutrition on the outcome and respiratory muscle strength of elderly patients in respiratory intensive care unit (RICU). Methods Totally 147 elderly patients in RICU were equally randomized into combined nutrition group ( combinination of parenteral nutrition and enteral nutrition), total enteral nutrition (EN) group, and total parenteral nutrition (PN) group. The changes of energy metabolism, respiratory muscle strength, and short-term outcome were observed or determined.Results Plasma albumin (ALB), hemoglobin (Hb), creatinine (Cr) levels, and nitrogen balance significantly increased in all group 7 days later ( all P ＜ 0. 01 ), while blood urea nitrogen (BUN) significantly decreased ( P ＜0.01 ). The increase of ALB, Hb, Cr levels, and nitrogen balance were significantly more remarkable than that in EN group and PN group (P＜0.05 or P＜0.01). The decrease of BUN level in the combined nutrition group was significantly more remarkable than that in EN group ( P ＜ 0. 05 ). After nutritional support, the maximum inspiratory pressure in the combined nutrition group (P =0. 021 ) and EN group (P = 0. 011 ) became significantly higher, and occlusion pressure at 0.1 second inspiration level in the combined nutrition group became significantly lower ( P =0. 025). The incidences of infectious and non-infectious complications in PN group were significantly higher than those in EN group (P = 0. 002 and 0. 017, respectively) and combined nutrition group ( P = 0. 005 and 0. 004, respectively). Gastric retention was more common in EN group than that in PN group ( P = 0. 035). The weaning time,length of RICU stay, length of hospital stay and 20-day-mortality were significantly decreased in the combined nutrition group than those in the other two groups ( all P ＜ 0. 05 ). Conclusion The effectiveness of the combined application of PN and EN is superior to PN or EN alone in improving nutritional status and respiratory muscle strength as well as in improving the short-term outcome in elderly patients in RICU..

AIM:To investigate the protective effects and mechanism of mesenchymal stem cells on renal tubule cells treated by cisplatin.METHODS:The mesenchymal stem cells(MSCs)were separated from mouse bone marrow.The necrosis and apoptosis rate of renal tubule cells induced by cisplatin were detected by flow cytometry.After co-culture with MSCs,the above changes of renal tubule cells were detected.RESULTS:In co-culture system,the apoptotic rates of renal tubule cell were decreased obviously and the cell number increased obviously.CONCLUSION:The MSCs protect the renal tubule cells from apoptosis induced by cisplatin.This effect may be related with the paracrine effects of MSCs.

Objective: Breast conserving surgery has been proved to be a safe strategy and widely applied to the treatment of early breast cancer.The aim of this work is to evaluate the operational techniques and effect of conservative surgery for breast cancer.Methods: We analyzed the clinical data of 20 patients with breast cancer that underwent conservative surgery from January 2004 to December 2007.All the tumors were found to be solitary,less than 3 cm in diameter,and treated by postoperative chemotherapy and radiotherapy.All the patients were followed for 5 to 52(mean 28) months.Results: During the follow-up,2 cases experienced local recurrence and received modified radical mastectomy.All the 20 patients remained alive up to the present study.Conclusion: The principle of specific procedures for specific cases counts quite a lot for satisfactory prognosis and outcomes of breast conservative surgery.

Pancreatic cancer is the third leading cause of cancer-related death in the world due to its high malignancy, difficult in early diagnosis, poor treatment efficacy, and high mortality. In recent years, benefiting from the progress of combined chemotherapy and neoadjuvant therapy, the prognosis of patients with pancreatic cancer has been improved to a certain extent. However, compared with other tumors, progress of precision medicine in pancreatic cancer is slow. The authors introduce the latest progress and difficulties in precision medicine of pancreatic cancer including molecular classification based on single gene and omics, monitoring tumor progression and guide treatment by minimally invasive liquid biopsy, as well as targeting therapy and immuno-therapy, in order to accelerate the development of precision medicine of pancreatic cancer.
