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.

OBJECTIVETo 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.

METHODSHuman 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).

RESULTSIn 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 significant differences 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.

CONCLUSIONSIn 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.

AIMTo observe the effect of mesenteric lymph duct ligation on free radical and inflammatory mediator of myocardium with severe hemorrhagic shock in rats at different period, and explore the effect of intestinal lymphatic pathway on myocardium injury pathogenesis in shock rats.

METHODS78 male Wistar rats were divided into the sham group, shock group and ligation group. The model of serious hemorrhagic shock was established in shock group, ligation group, and mesenteric lymph was blocked by ligating mesenteric lymph duct in ligation group after resuscitate. All rats were executed and taken out heart making for homogenate of 10 percent to determine the MDA, SOD, tumor necrosis factor-alpha (TNFalpha), interleukin-6 (IL-6), myeloperoxidase (MPO), NO and NOS at after shock 90 min, after transfusion and resuscitate 0 h, 1 h, 3 h, 6 h, 12 h and 24 h etc. different times, and the expression of inducible nitric oxide synthase (iNOS) mRNA in myocardium was detected by RT-PCR.

RESULTSThe contents of MDA, TNFalpha, IL-6, MPO, NO, NOS and iNOS expression in myocardium of shock group were rising after transfusion and resuscitate, and that was higher level at 3 h to 12 h, and that was significantly higher than sham group, the activity of SOD was significantly lower than sham group. The contents of MDA, TNFalpha, IL-6, MPO, NO, NOS and iNOS expression in myocardium of ligation group were significantly lower than that of shock group at sameness points, and the SOD activity was higher.

CONCLUSIONThe mesenteric lymph duct ligation and blocking mesenteric lymph could reduce the PMN detaining, decrease the discharging of TNFa and IL-6, reduce the NO and expression of iNOS mRNA, and reduce the releasing of free radical and consuming of SOD.

OBJECTIVETo study the effects of prenatal exposure to benzo[a]pyrene (B[a]P) on the physical development, early behavioral development, the adaptability to new environment and the learning and memory ability of rat offspring.

METHODSPregnant rats were randomly divided into five groups: control group, olive oil group, 3 exposure groups (25, 50 and 100 mg/kg B [a]P). The rats were exposed to B [a]P) by intraperitoneal injection on the 17th-19th days during gestation. The offspring were weighed on postnatal days (PND)1, PND 4, PND 7 and PND 28, the indices of physical development, reflective ability and sensory function were detected for offspring, the Morris water maze and Open-field tests were used to measure the ability of learning and memory and the adaptability to new environment of offspring.

RESULTSThe time of ear opening in middle and high-dose groups [(4.1 +/- 0.4),(5.0 +/-0.4) d] was posterior to that in untreated and solvent groups [(3.3 +/- 0.5), (3.4 +/- 0.6) d ](P < 0.01). The attainment rate (6.5%) of the surface righting reflex test in high-dose group on the 4th day was significantly lower than that (36.1%) in untreated group, the attainment rate (50.0%) in high-dose group on PND7 was significantly lower than those (81.3% and 79.3%) in untreated group and solvent group (P < 0.05). Compared to the untreated group, the time of forelimb hanging test in all exposure groups on PND12 and PND14 significantly decreased; compared to the solvent group the time of forelimb hanging test decreased in high-dose group on the 14th day significantly decreased (P < 0.01). The attainment rate (61.9%) of olfactory discrimination in high-dose group on PND12 was significantly lower than that (94.3%) in untreated group (P < 0.05). The results of Morris water maze test showed that the escape latency of different dose groups significantly increased, and the time of spatial probe and the times of traversing flat in high-dose group decreased significantly, as compared to the untreated and solvent groups (P < 0.01). The results of open-field test indicated that the center retention time in middle and high-dose groups significantly prolonged, the times of crossing lattice obviously reduced, and the rearing times decreased in high-dose group, as compared to untreated (P < 0.05).Compared to the solvent group, the times of crossing lattice in all exposure groups reduced significantly (P < 0.01 or P < 0.05).

CONCLUSIONThe prenatal exposure to B[a]P could inhibit the physical development and early behavioral development, and influence the adaptability to new environment and learning and memory ability for offspring.
