5 years)from a basketball team before and after tapping,as well as every 10 minutes of playing.Exercise intensity is determined in accordance to 80% intensity(average of six matches) of China National Men Basketball Team performed at Beijing Olympic Games.Results Data show that ankle tapping restricts ankle ROM from the beginning of playing(P 0.05).Conclusion The protective effect of ankle taping is weakening with the prolongation of playing,and thus it's necessary to have a second taping at the halftime of the basketball game.

Objective To summarize the clinical features of diabetic ketoacidosis (DKA) in children with newly diagnosed type 1 diabetes mellitus(T1DM),and to explore the predictors of DKA by analyzing these factors in order to achieve early recognition.Methods In this retrospective study,200 children with newly-onset T1DM from January 2009 to December 2012 in Shengjing Hospital of China Medical University were chosen.These patients were divided into DKA group and non-DKA group.Clinical data including age,gender,health insurance,body shape,infection history,family history of diabetes,type of residence,income,duration of history,C peptide,glycosylated hemoglobin,blood lipids,thyroid tests,diabetes antibodies etc were collected.Results Among 200 cases of newly diagnosed T1DM,107 children had DKA,93 children had non-DKA,and the incidence of DKA was 53.5％.In the group of DKA,39 cases (36.5％) were male,68 cases were female,while in the group of non-DKA 45 cases (48.4％) were male,48 cases were female.In the group of DKA,children ranged in age from 16 months to 13 years old,and the average age was (6.53 ±3.55) years old.In the non-DKA group,children ranged in age from 1 to 14 years old,and the average age was (7.05 ± 3.55)years old.In the group of DKA,43 cases (40.2％) didn't have health insurance,while in the non-DKA group,28 cases (30.1％) didn't have medical insurance.In the DKA group,30 cases (28％) had a family history of diabetes,while in the non-DKA group,27 cases (29％) had a family history of diabetes.In the group of DKA,the duration was (30.24 ± 76.50)days,while in the group of non-DKA,the duration was (33.38 ± 49.30) days.The glycosylated hemoglobin in the DKA group was (12.38 ± 2.66)％,in the non-DKA group was (12.48 ± 2.24) ％.There were no significantly differences of the above factors between the 2 groups (all P ＞ 0.05).In the group of DKA,35 cases(32.7％) were thin,66 cases(61.7％) were of normal size,and 6 cases(5.6％) were fat.In the group of non-DKA,9 cases(9.3％) were thin,76 cases (78.6％) were of normal size,and 8 cases(12.1％) were fat.In the group of DKA,33 cases (30.8％) had infection history,77 cases (72％) lived in rural areas,and the average of C peptide was (0.25 ± 0.22) μg/L.In the group of non-DKA,17 cases (18.3％) had infection history,52 cases(55.9％) in rural areas,and the average of C peptide was (0.36 ± 0.21) μg/L.There were significant differences of the above factors between the 2 groups (all P ＜ 0.05).Conclusions Children with newly diagnosed T1DM who is thin,rural resident,and has lower C peptide level is more susceptible to DKA.More attention should be paid to the children with newly diagnosed T1DM who have above characteristics.

BACKGROUND:As a good candidate for bioresorbable bone graft, carbonate apatite monolith can be prepared by sintering procedure;however, sintering can cause carbonate loss and result in a much lower rate of
biodegradation compared to the human bone, thereby influencing the formation of new bone.
OBJECTIVE:To fabricate low-crystal inity carbonate apatite monolith as bone graft and test its properties. METHODS:Calcium carbonate monolith prepared by carbonation of Ca(OH) 2 monolith was treated in 1 mol/L
RESULTS AND CONCLUSION:The calcium carbonate completely transformed into low-crystal inity B-type
carbonate apatite after treated for 14 days. Diametral tensile strength of the final product was (10.27±1.08) MPa, which is adequate as a reconstruction material for bone defect. The carbonate content was (4.80±0.50)%, similar to that of the nature bone. The molar Ca/P was 1.63±0.01, indicating the Ca-deficient carbonate apatite is
obtained. The present method al ows an easy fabrication of low-crystal inity B-type carbonate apatite block with adequate strength and without sintering process.
ammonium dihydrogen phosphate solution at 60 ℃ up to 14 days. Diametral tensile strength was examined for biomechanical properties;X-ray diffraction analysis, Fourier transform infrared spectroscopy, scanning electron microscope observation and chemical analyses (carbonate, calcium and phosphate content) were also performed for physical and chemical properties.

AIM: To understand the influence of national constitution monitoring on sports behavior, attitude and physique of the investigators. METHODS: The study was performed at the Constitution Monitoring Center of Chenzhou Sports Bureau from March to December 2005. 285 public servants of Chenzhou were enrolled as investigators for the first study in 2005 and the second after 10 mouths with questionnaire. Age was accorded with the first measurement. 283 valid data were included (168 males and 115 females), because 2 could not participate in the constitution measurement. Questionnaire in 2006 involved individual physical awareness, behavior, attitude, participating rate, and whether doing the questionnaire according to the physical exercise prescription in the first monitoring. RESULTS: Significant differences in cardiovascular function, strength and sensitivity were detected between testees and national average value, especially in males and middle-age persons and youth. Nine months later, significant difference was found after paired test, step test and in vital capacity improvement. Improvement in other indexes had differences in age and sex. CONCLUSION: The measurement on national constitution is good for realizing their own state of health, improving their sports consciousness, increasing their frequency of doing sports greatly, and improving the physical state, especially for middle-aged and elder persons.

Objective To observe the lung inflammation and the expression of T - helper cell related cytokines in respiratory syncytial virus(RSV) infected Balb/c mice pre - sensitized with ovalbumin(OVA). Methods Mice were randomly divided into two series: nonsen-sitized and sensitized animal model with nebulized OVA once a day for 10 days. Each of the series was divided again into two groups: control group,RSV infected group with nasal draping plus nebulizing. All the mice were sacrificed 5 days later of infection. Viral isolation of lung organization was performed in each group. Pulmonary pathological detection and the levels of interleukin - 4(IL-4), interferon-? (IFN- ?) mRNA were evaluated by RT- PCR. Results The RSV were found only in RSV infected groups. The Balb/c mice developed typical interstitial pneumonia after RSV infection. When the mice pre- sensitized were infected with RSV, the pulmonary inflammation, lymphocyte and eosinophils infiltration and cell - collar peribronchiles were more severe in lung organization and bronchiole than those in the single RSV infection group. In the lung organization of control group, there were no mRNA expression of IL - 4 and IFN - ?. The mRNA of IFN -? was expressed in the lung organization of RSV infected groups while had not showed mRNA of IL- 4. In the OVA+ RSV group the mRNA expression of IL - 4 was obvious, while the expresses of IFN -? scarcely. Conclusions Pulmonary inflammation is more severe in the infection after OVA sensitization. RSV infection alone results in a Th1 - like cytokine response, while the infection after OVA sensitization results in Th2 - like response.

Objective To establish a patient-like human ovary carcinoma/spontaneous metastasis model using orthotopic transplantation of histologically intact tumor tissue. Methods An highly metastatic ovarian tumor line (8910PM: human serum carcinoma of the ovary) previously grown substaneously was transplanted into the ovicapaule using microsurgery technique. Histologically intact human ovary tumor pieces gained from implantation site were passaged between ovicapsules for four generations. Results All mice developed ovary tumors and the metastatic rates were about 50 %. The tumors only metastasized to liver. The earliest appearance of metastasis was 14 days and the average survival period was 20.7 ±4.89 days. The microscopic appearance of the metastases was similar to the tumor observed in the substaneous xenografts and orthotopically transplanted.Chromosomes analysis exhibited the feature of human carcinoma and retained genetic stability during the processes of passage. Conclusion Orthotopic implantation provides a suitable micro-environment in which ovarian cancer can express its intrinsic clinically-relevant properties. This approach is relevant to the spontaneous development of ovarian cancer and is thought to be a useful model for studies of metastatic mechanism and therapy for ovary cancer.
