Objective To investigate the association between serum N-terminal pro brain natriuretic peptide(NT-ProBNP) and creatine kinase myocardial(CK-MB),cardiac troponin I(cTnI) in children who were diagnosed as viral myocarditis(VMC),and to explore the clinical significance.Methods Fifty children with VMC were selected as VMC group who were further divided into cTnI(+)group and cTnI(-)group.Fifteen healthy children were selected as healthy control group.The levels of myocardial enzyme of the 2 groups were tested by automatic biochemical analyzer and level of NT-proBNP was detected by specific NT-proBNP enzymelink immunosorbent assay(ELISA) kit.SPSS 13.0 software was used to analyze the data.Results 1.There were 23 cases with positive cTnI and 27 cases with negative cTnI.The levels of NT-proBNP in VMC group including cTnI positive and cTnI negative were significantly higher than those in healthy control group (P0.05).2.In the group with positive cTnI,the level of NT-proBNP was correlated with cTnI.The coefficient of determination was 0.17.3.In the group with negative cTnI,the level of NT-proBNP was correlated with CK-MB.The coefficient of determination was 0.34.NT-proBNP presented a increasing trend during interval of 25-100 U?L-1 and 175-255 U?L-1 of CK-MB.Conclusions The levels in the serum NT-proBNP in VMC children were higher than those in healthy children.Serum detection NT-proBNP may be applied as a new approach in diagnosis of VMC in children.

Objective To study the validity of furosemide test for predicting the hematoma enlargement in pa- tients with hypertensive cerebral hemorrhage.Methods Four hundred fifty-one patients with hypertensive cerebral hemorrhage were diagnosed using CT after oneset of the disease and 24 h reexamined 24 h after.The incidence of enlarged hematoma was evaluated by comparison the baseline and 24 h CT scanning.Furosemide(20 mg iv)was ad- ministered and blood pressure was measured 30 min after furosemide.Results The decreasing level of MAP after furosemide was significantly inversely related with incidence rate of hematoma enlargement{ r=-0.94,t=58.4,P 10 mmHg as the cut-off point,with the rate of hematoma enlargement as being 6.4 %,MAP decreased≤10 mmHg was associated with increases in prevalence of hematome to 33.2 %(?~2=51.82, P

Objective To investigate the relationship between carotid atherosclerosis(CAS)plaque and its related factors and cerebral infarction(CI).Methods The 91 patients with CI were detected by Color Doppler and the levels of plasma lipid,blood glucose(BG)and fibrinogen(Fbg)were evaluated,and compared with normal control(NC)group.Results(1)Compare with NC group,the IMT,prevalence of CAS plaque,the rates of soft plaque in CI group were significantly higher(all P

0.05).Conclusion: For teeth with perforation in root canal therapy,the Propex,Raypex 5 and Root ZX electronic apex locators can detect the perforation with high accuracy.

Aim The relative bioavalability of hydrochloride eperisone granule in 10 healthy volunteers was studied. Methods The time-plasma concentrations of hydrochloride eperisone granule, as test drug, and myonal, as reference drug, were determined by GC-MS, with tolperisone senuing as internal standard.The pharmacokinetic parameters of both reference and test drug were calculated and analyzed with two-one side test and confidential interval test. Results The results showed that the AUC0-8, AUC0-∞, Cmax, Tpeak, t1/2(?) and t1/2(?) were (17.9?1.3)ng?h?ml-1 and(18.6?1.6)ng?h?ml-1, (19.1?1.2)ng?h?ml-1 and (20.2?1.6)ng?h?ml-1, (5.2?0.5)ng?ml-1 and (5.4?0.5) ng?ml-1, (1.05?0.18)h and (1.08?0.23)h, (0.78? 0.13)h and ( 0.82?0.14)h,( 1.8?0.3)h and (1.8?0.3)h, respectively. The relative bioavalability of test drug was (105? 5)%. Conclusion It can be concluded that the test and reference are bioequivalented between individuals, preparations and periods.

Objective To investigate the MR features of pituitary abscess.Methods The MR features of 14 cases of pituitary abscess proved by surgical pathology and clinical treatments were analyzed retrospectively.Results Pre-contrast MR showed hypointense heterogeneous intensity on T_1 WI in 12 cases and iso-hyperintense on T_1 WI in 2 cases,hyperintense on T_2 WI in all cases.Post-gadolinium MR showed the ring-like enhancement around the uneven edge of abscess and the surrounding enhanced meninges connecting to the focus.The normal pituitary could not be identified in all 14 cases.The MR specific findings include the fluid-fluid level,nodule on the edge and the enhanced patchy shadow.Conclusions The pituitary abscess has specific findings on MR examination,which can be used to combine with clinical symptoms to achieve the diagnosis before operation,so that the cases could be treated with antibiotic without operation.

Human tissue kallikrein-binding protein (Kallistatin, KAL), a secretory protein that participates in the regulation of multiple signaling pathways by binding to the extracellular receptor, however, at present has not been reported about the intracellular activity, and whether it has the similar biological activity with extracellular activity. Here we constructed no signal peptide KAL (NSK) into the adeno-associated virus vector to explore the intracellular activity of KAL. Both the endothelial cell and lung cancer cells could express KAL, but not secreted after rAAV2-NSK transfection. The proliferation and migration of human umbilical vein endothelial cells (HUVECs) were inhibited, but the apoptosis rate was not affected. The proliferation rates, mobility and tubule formation of all the three tested lung cancer cells, such as NCI-H446, NCI-H460 and A549, were inhibited to different extents. This cellular study not only confirmed the intracellular activity, but also suggested it may serve as a kind of "balance factor" in multi-targeted controlling, which may provide a new train of thoughts to explain the regulatory contradiction in PI3K-Akt signaling pathways by KAL.

Objective To investigate the changes of insulin-like growth factor-1(IGF-1) and its associated protein in Balb/C mice with viral myocarditis.Methods Sixty Balb/C mice were randomly divided into 2 groups:infected group(n=40) and control group(n=20).Mice in infected group were inoculated intraperitoneally with coxsackievirus B3(CVB3) while control mice with 0.1mL of Eagle′s minimal essential medium(EMEM).Blood and myocardial musculature of all mice were collected on the day of 3,7,15 and 30 after inoculation.The expression of IGF-1 and its associated protein in plasma or myocardium were detected respectively by enzyme-labeled immunosorbent assay(ELISA),immunohistochemistry and reverse transcription polymerase chain reaction(RT-PCR).Results The expression of IGF-1 and its associated protein of mice with viral myocarditis was higher than those in control group and gradual ascent after mice being infected with virus.The expression reached summit on d15,then decreased on d30,but still sustain in a high level.The difference was significant(F=19.53 P
