Objective: To compare the clinical characteristics and plasma level of N-terminal pro-brain natriuretic peptide (NT-proBNP) between the patients with hypertensive hypertrophic cardiomyopathy in elder age (HHCME) and the patients with hypertensive left ventricular hypertrophy (HTN-LVH).
Methods: Our work included 2 groups, HHCME group,n=47 and HTN-LVH group,n=44. Duplex Doppler echocardiography was performed to determine left atrial diameter (LAd), left ventricular end-diastolic dimension (LVEDd), interventricular septal thickness (IVST), left ventricular ejection fraction (LVEF), velocity of early diastolic period (VE) and velocity of end-diastolic period (VA) in mitral valve oriifce. Plasma level of NT-proBNP was measured by ELISA. The above indexes were compared between 2 groups.
Results:①Compared with HTN-LVH group, HHCME group presented decreased LVEDd and increased IVST, LVEF, allP<0.001. There were no signiifcant differences in VE/VA ratio and LAd between 2 groups, allP>0.05.②Plasma level of NT-proBNP was higher in HHCME group,P<0.01. With the adjusted age, gender, history of hypertension, LAd, IVST, left ventricular systolic and diastolic function, the level of NT-proBNP in HHCME group (1317.19 fmol/ml) was still signiifcantly higher than that in HTN-LVH group (526.19fmol/ml),P<0.01.
Conclusion: The plasma NT-proBNP level was higher in HHCME patients than that in HTN-LVH patients which indicated that HHCME patients may have worse prognosis. NT-proBNP might be helpful for differencing HHCME.

Objective To investigate the effect of insulin-like growth factor- Ⅰ ( IGF- Ⅰ ) on the proliferation and osteogenesis of human periodontal ligament stem cells ( hPDLC ) under three-dimensional (3D) culture system. Methods Human periodontal cells were isolated from the ligament of surgically extracted human teeth, and through the limiting dilution assay, got mono-clone of the cell, hPDLCs were isolated from MesenPRO RS medium. Rotary cell culture system (RCCS) was enrolled to set 3D environment. Control group and experiment groups were assigned according to the concentration of IGF- Ⅰ .There were 5 level of experiment groups (0.1,1,10,50,100 μg/L). Proliferation was tested with methyl thiazolyl tetrazolium ( MTT), and alkine phosphatase (ALP) level was assayed by spectrophotometer to analyze the osteogenesis of hPDLCs. Gene expression of ostetocalcin(OCN)and type Ⅰ collagen (Col Ⅰ )were assayed by reverse transcriptase polymerase chain reaction(RT-PCR). Results In 3D culture system,the effect of IGF- Ⅰ on cell proliferation was significantly different between control group and experiment groups( P < 0.05 ), and there showed significant differences between the group of 0.1 μg/L ( 0.219 ±0.021 ) IGF- Ⅰ and the groups of 50, 100 μg/L(0.287 ±0.011,0.293 ±0.012). However, there showed no significant differences among other groups. Significant differences of ALP activity were observed between the control group and experiment groups, and between the groups of 1, 10 μg/L(0.304 ±0.020, 0.310 ±0.013) and that of 50, 100 μg/L (0.347 ±0.011, 0.344 ±0.010) (P <0.05). While no significantdifferences were detected between the group of 1 μg/L and that of 10 μg/L, nor between the group of 50 μg/L and that of 100 μg/L. Expressions of Col Ⅰ and OCN in mRNA and protein level both showed dose-dependent increase. Conclusions In 3D culture system, in the scale of 0.1-100 μg/L, the effect of IGF-Ⅰ on the proliferation of hPDLCs increased dose-dependently. 100 μg/L IGF- Ⅰ promotes osteogenesis of the cells significantly.

OBJECTIVETo investigate the absorption mechanism of genistein self-microemulsifying system in rat intestines.
METHODThe concentrations of phenol red and genistein by in situ perfusion in rats were determined by UV and HPLC, respectively. The effects of drug concentrations, pH, various intestinal segments and P-glycoprotein (P-gp) inhibitor verapamil on the absorption had been studied.
RESULTThe absorption rate constant (Ka) of genistein had no significant difference at concentrations of 0.05-0.5 mg x mL(-1) and pH of 5.4-7.8 in perfusion. It was Ka of jejunum > ileum > duodenum > colon. The absorption of genistein in jejunum had significant difference (P < 0.05) compared with other parts of intestines. Ka was increased obviously when verapamil was coper-fused with genistein (P < 0. 05).
CONCLUSIONThe absorption of genistein self-microemulsifying system is a first order process with passive diffusion mechanism related to P-gp efflux. It can be absorbed at all segments of rat intestine, and the jejunum is the best absorption segment, pH had no special effect on the absorption of genistein self-microemulsifying system in rat intestine.

OBJECTIVETo observe the effects of mesenteric lymph duct (MLD) ligation on erythrocyte rheology in acute hemorrhagic rats.
METHODSTwenty male Wistar rats were randomly divided into hemorrhage group and ligation group (n = 10). Blood (one fourth of body whole blood volume) was withdrawn through right common carotid arteries after rats were anesthetized. In ligation group, the MLD was ligated after hemorrhage, and only threading under the MLD in hemorrhage group. The survival situation at 24 h was recorded. After 24 h, survival rats were anesthetized again, blood sample was withdrawn through left common carotid artery rapidly. And the erythrocyte sedimentation rate (ESR), electrophoresis of erythrocytes, hematocrit (Hct) were determined in blood samples of before and after hemorrhage, the erythrocytes aggregation and deformability indices were calculated.
RESULTSIt showed that the ligation group survival (9 rats alive) was slightly better than that in hemorrhage group (6 rats alive). The results of erythrocyte rheology indices showed that the ESR, K value of equation, K value of emendation and electrophoresis time in hemorrhage group and ligation group were higher or longer than those before hemorrhage, the erythrocyte deformability was reduced significantly, respectively. And the erythrocytes aggregation index in hemorrhage group was increased, the electrophoresis length and migration of erythrocyte in hemorrhage group were lower than those before hemorrhage, respectively. But compared with hemorrhage group, the ESR, K value of equation, K value of emendation, erythrocytes aggregation index and electrophoresis time in ligation group were lower, the electrophoresis lenght, migration and deformability of erythrocyte were increased significantly.
CONCLUSIONThe results indicate that the higher erythrocyte aggregation ability, lower electrophoresis function and deformability are caused by acute hemorrhage in rats, and the MLD ligation can improve the abnormal erythrocyte rheology.
