Objective To observe the effect of ageand menstrual statuson body composition in healthy Beijing women.Methods We measured body composition with dual-energy X-ray(GE Lunar Prodigy)in 316 healthy Beijing females aged 20 to 74 years(5-7 cases per age).Parameters provided by the software were as following:total body bone mineral content,lean mass,fat mass and fat percentage(% fat).Local regions measured included arm,leg,trunk,android region and gynoid region.Body mass index (BMI),fat mass index(FMI),free fat mass index(FFMI)and A/G were calculated.Volunteers were assigned to 6 groups according age by every ten years a group.Results BMC peaked during the 4th decade,LM peaked during the 5th decade,with a decline of 18.1%and 5.2%respectively at age 74 years.Total body fat mass and % fat showed a general increase with aging throughout the studied age range.Total body fat mass increased from 16±5 kg at age 20-29 years to 24±6 kg at age 70-74 years,while % fat increased from 31.3%to 39.5%.All local region % fat increased with aging at different extents.Android region % fat showed the largest raise extent(32.2%).BMI increased gradually from 21.1 kg/m2 at age 20-29 years to 26.1 kg/m2 at age 70-74 years.FMI changed more obviously than FFMI.A/G increased from 0.85 at age 20-29years to 1.02 at age 70-74 years.Different menstrual status in women of 40-59 vears had obvious eflfect on A/G and BMC(P＜0.05),while it had no significant effect on BMI.body weight and waist circumference(P＞0.05). Conclusions Aging and menstrual status have evident effect on body composition distribution in healthy Beijing women.

Objective To investigate and evaluate the correlation between brain natriuretic peptide (BNP) and gestational hypertension and preeclampsia of hypertensive disorder complicating pregnancy (HDCP).Methods Fifty cases with HDCP and 46 cases with mild and 83 cases with sever stage preeclampsia were selected as our subjects.And 33 cases with regular pregnancy and 31 with irregular pregnancy were served as control group.Plasma brain natriuretic peptide,urinary protein quantity(UBQ),24-hour urinary protein assay (UPA) were measured.The correlations of brain natriuretic peptide and UBQ,UPA,systolic pressure (SP),diastolic pressure (DP) were analyzed.Results The levels of brain natriuretic peptide in the group with gestational hypertension and mild,severe preeclampsia groups were (48.54± 18.27),(79.46± 32.18) and (292.24±213.08) ng/L,higher than that in normal pregnancy and non pregnant group ((27.84± 14.58) and (20.63± 8.28) n/L;F =49.583,P＜0.05).While no significant difference exists between normal pregnancy group and non pregnant group.Grouped on the median values (199) of brain natriuretic peptide of the severe preeclampsia group,the levels of 24-hour UPA,systolic pressure and diastolic pressure were (5.46±2.68) g,(174.55± 13.58) mmHg,(113.74±9.91) mmHg in patients with brain natriuretic peptide ≥ 199 ng/L(n=42),significant higher than those in patients with brain natriuretic peptide ＜ 199 ng/L(n =41;(4.34± 1.95)g,(165.31±11.12) mmHg,(106.05±8.02) mmHg;t=2.603,3.396,2.308;P=＞0.010,0.001,0.024).The levels of 24-hour UPA,systolic pressure and diastolic pressure of patients with brain natriuretic peptide ≥ 86ng/L(n=20) in mild preeclampsia were (1.68±0.27) g,(163.69±8.29) mmHg,(105.45±6.71) mmHg,significant higher than those in patients with brain natriuretic peptide ＜ 86 ng/L (n =26;(1.16 ± 0.31) g,(152.90±7.32) mmHg,(99.19 ± 5.25) mmHg;t =3.180,2.508,2.32;P =0.010,0.016,0.025).Brain natriuretic peptide was closely correlated with UPA,systolic pressure and diastolic pressure in hypertensive disorder complicating pregnancy (HDCP) (r =0.29,0.30;P ＜ 0.01).Brain natriuretic peptide was closely correlated with UPA systolic pressure and diastolic pressure in mild preeclampsia (r =0.39,0.37,0.40;P ＜0.01).And correlation efficacy of brain natriuretic peptide with UPA,systolic pressure and diastolic pressure were 0.44,0.42 and 0.53 (P＜0.01).Conclusion The level of brain natriuretic peptide is closely associated with the severity of gestational hypertension and preeclampsia of hypertensive disorder complicating pregnancy.Correlation of brain natriuretic peptide to the severity of gestational hypertension and preeclampsia is independent of urinary protein and hypertension.Brain natriuretic peptide is an important indicator for the severity of gestational hypertension and preeclampsia of hypertensive disorder complicating pregnancy.

In order to study the effect of 5, 6-Dichloro-1-beta-D-ribofuranosyl-benzimidazole (DRB) on the biological characteristics of human laryngeal carcinoma Hep-2 cell line in vitro, Hep-2 cells cultured in vitro were treated with different concentrations of DRB. Changes in cell proliferation, apoptotic rate and invasiveness were detected by MTT assay, flow cytometry (FCM) and matrigel in vitro invasion assay, respectively. It was found that DRB inhibited the proliferation of Hep-2 cells in a dose-and time-dependent manner. After being treated with 0, 10, 20, 40, 80 microm mol/L DRB for 24 h, the apoptotic rate in Hep-2 cells was (0.68+/-0.19)%, (1.95+/-0.12)%, (8.51+/-0.26)%, (11.26+/-0.17)% and (14.99+/-0.32)%, respectively. The matrigel in vitro invasion assay revealed that DRB began to inhibit the invasion of Hep-2 cells at the concentration of 5 microm mol/L, and with the increase of DRB concentration, the inhibitory effect was enhanced. It was suggested that DRB could influence the essential biological characteristics of Hep-2 cells, inhibit Hep-2 cells proliferation, reduce invasive ability and induce apoptosis of Hep-2 cells.

OBJECTIVE: To explore the methods of culture, identification and label of embryonic rat neural stem cells. METHOD: The cells isolated from fetal rat hippocampus were identified with nestin immunocytochemical fluorescent staining. The cellular multiplication was observed by immunocytochemical fluorescence co-label after accession of BrDU. The neural stem cells (NSCs) were marked with fluorescent dye, bisbenzimide (Hoechest33342) and induced to differentiate. The differentiated cells were detected with Neuron Specific Enolase (NSE) and Glial Fibrillary Acidic Protein (GFAP) immunocytochemical fluorescent staining respectively. RESULT: Nest-like clusters of neural stem cells were obtained in suspension and the cells could be differentiated into neurons and astrocytes which maintaining the main characteristics of NSCs after 8 passages of culture. The label efficiency of cells with Hoechest33342 was 97% and no attenuation of fluorescent brightness was observed after 8 passages of culture. The cellular fluorescence was observed in the NSCs and the differentiated cells. CONCLUSION The cells from embryonic rat hippocampus possessed the abilities of division, multiplication and self-renew, which were believed to be the main characteristics of NSCs of the central nervous system. The cells could be efficiently labeled with fluorescent dye and could be used as donor cells in experimental research on NSCs transplantation.

OBJECTIVE: To observe the changes of auditory electrophysiology and inner ear pathology in rat cochlea after the noise exposure, and to offer the experimental data for exploring the mechanism of noise-damaged cochlea. METHOD: The rats in the study group were exposed to a intense narrow band noise centered at 4 kHz at the leave of 120 dB (SPL) for 4 h. The exposed cochleae were collected at various intervals (1 or 21 days) after the noise exposure. Auditory function was monitored by measuring thresholds of auditory brain stem responses (ABR). The morphological changes in rat cochlear hair cell (HC) were examined by HC nuclei stained with Propidium iodide (PI), a fluorescent dye specifically labelling the nuclear DNA and scanning electron microscopy (SEM). The number of spiral ganglion cells was calculated using pathologic technique. RESULT: The thresholds of ABR in the study group were significantly greater than that in the normal control group (P < 0.01). Examined at 1 day after the noise exposure, normal, apoptosis, necrotic and missing out hair cell (OHC) could be distinguished with PI staining, whereas the apoptosis OHC were not found at 21 days. Significant OHC loss was found in as compared to the normal control group (P < 0.01). There was not significant difference in the calculation of spiral ganglion cells (P > 0.05). SEM revealed the injured stereocilia of OHC (disarrangement, collapse) and OHC loss in the study group, which was more severe in OHC3 than the other two rows of OHC. CONCLUSION The intense noise used in our study could injure the rat cochlea and bring permanent threshold shift (PTS). Under this condition, the death modes of HC in the cochlea include apoptosis and necrosis in the fore part, whereas necrotic is the major mode in the evening of exposure. The injured stereocilia of OHC and OHC loss could remain the most consistent correlate of PTS.
