ABSTRACT
BACKGROUND: Osteoporosis is easily seen in postmenopausal women. The bone loss situation is different among populations of different age and body mass.OBJECTIVE: To analyze the effects of age, menopausal duration,menopause age, height, body mass and body mass index on bone mineral density (BMD) in postmenopausal women.DESIGN: Random sampling test was conducted to postmenopausal women.SETTING: A clinical trial center of a provincial Chinese traditional medicine research institute, an orthopaedic department of a university hospital and a bone wound department of a university.PARTICIPANTS: Totally 603 naturally postmenopausal women in Fuzhou area from September 2000 to August 2003.METHODS: Random sampling method was used. The age of participants,menopausal duration, menopause age, height, body mass and bone mineral index(BMI) were recorded. Dual energy X-ray bone mineral density machine was used to examine the bone mineral density of lumbar, neck of femur, great trochanter and Ward' s area while SPSS software was used to conduct regression analysis.MAIN OUTCOME MEASURES: The correlation between age,menopausal years, menopause age, height, body mass, BMI and bone density as well as the regression equation.RESULTS: There was very significant correlation between age, menopausal duration, body mass, BMI of postmenopausal women and bone mineral density of lumbar, neck of femur, great trochanter and Ward' s area. The BMD in low body mass group is greatly lower than that of obesity group( P < 0.01 ). The main factors impacting BMD of lumbar are in turn age, body mass and menopause age while the regression equation: y = 0. 927 - 0. 0093 X1+ 0. 0037X2 + 0. 004X3. The factors impacting BMD of neck of femur are in turn menopausal duration, body mass, menopause age and the regression equation was: y = 0. 687 - 0. 0081 X1 + 0. 0048 X2 - 0. 0034 X3. And the factors affecting BMD of greattrochanter are age, body mass and menopause age while the regression equation was y = 0. 591 - 0. 0038 X1 + 0. 0042 X2 - 0. 0024 X3. Age, body mass index and menopausal duration are main factors affecting BMD of Ward' s area and the regression equation was y =0. 686 -0. 0072 X1 +0. 0136 X2 -0. 0046 X3.CONCLUSION: The BMD of lumbar and hip gradually decreases with the increase of age in postmenopausal women. The risk of getting osteoporosis in people with low body mass is greater than women in normal body mass groupand obesity group.
ABSTRACT
OBJECTIVE: We used the SD rat's bone marrow stromal cells (BMSCs) cultured in vitro to observe the effects of Bugu Mixture on the apoptosis and to explore the molecular biologic mechanism of the treatment of osteoporosis with Bugu Mixture. METHODS: BMSCs were separated from the bones of the extremities of SD rats in vitro. The morphologic changes, the apoptosis cell cycles, the mitochondrion membrane potential changes, and the Bcl-2 and Bax gene expression were observed, and the effects of Bugu Mixture on the course of cell apoptosis were evaluated. RESULTS: The earlier use of Bugu Mixture could decrease the cells blocked in G0/G1 phase, and promote their synthesis of DNA in S phase. The expression of Bcl-2 was higher in the Bugu Mixture group than that in the all-trans retinoic acid (ATRA) induced group, and the expression of Bax was lower in the Bugu Mixture group than that in the ATRA induced group. The mitochondrion membrane potential descended significantly in the Bugu Mixture group than that in the ATRA induced group. CONCLUSION: The mechanism of the treatment of osteoporosis with Bugu Mixture is that the earlier use of Bugu Mixture can decrease the amount of apoptostic cells induced by ATRA, thus promoting the cell mitosis and restraining the apoptosis. It can also act as a protector to Bcl-2 located on the mitochondrion membrane. By preventing the transferring of the Bax protein from cell-plasma to mitochondrion membrane, it takes the advantage of Bcl-2 in forming Bcl-2/Bax homodimer so as to prevent the opening of the permeability transition pore to avoid the changing of mitochondrion membrane potential and the destruction of biosynthesis caused by the mitochondrion release of apoptosis inducing factors and to reach the objective of restraining apoptosis.

ABSTRACT
objective To study the inhibition effect and its mechanism of a non - cytotoxic chemotherapy drug in the growth of gastric cancer. Methods The inhibition effect was observed in the growth of xenotransplanted gastric cancer cells MKN45 with a gastrin receptor(GR) antagonist. On the basis of the determination of expressed GR in 34 patients with gastric cancer, we evaluated the preliminary clinical effect of PGL to gastric cancer with the positive GR. Results It is less tumor area, weight and gastric cancer cells DNA Index, average DNA contents and S phase fraction in PGL group than in control group. It is the least in PGL + SST group. GR is easy to be expressed in advanced gastric cancer of the body, cardia and fundus. With the 16-21 months follow- up of 14 patients with positive GR gastric cancer, we find that 2 patients died in control group of 8 patients, and all patients are alive in PGL group. Conclusion PGL can regulate the growth of gastric cancer cells MKN45. It would be able to improve the prognosis of gastric cancer.
ABSTRACT
Objective To observe the distribution and origins of the nitrergic perivascular nerves in rat cerebral arteries with a histochemical method for reduced nictinamide adenine dinucleotid phosphate(NADPH) diphorase activity, after resecting the membraneous structure at the ethmoidal formen. Methods Health adult SD rats were randomly distributed to three groups:sham operation group(group A), unilateral (right) operation group(group B), and bilateral operation group (group C). Both group B and C were further divided into two groups: group of resection of membraneous structure and nasociliary nerve (group BⅠ,CⅠ), and group of only removing membraneous structure (group BⅡ, CⅡ). On the seventh day after operation, the pterygopalatine ganglia and otic ganglia of group A were taken, and striped the cerebral arteries of three groups. With the method of NADPH d we investigated the positive cells in pterygopalatine ganglia, otic ganglia, and the changes of positive perivascular nerve fibers. Results A great deal of NADPH d positive cells were found in both pterygopalatine ganglia and otic ganglia. After unilateral operation, the NADPH d positive nerves in the ipsilateral middle cerebral artery(MCA) completely disappeared, but it did not change on the contralateral MCA. The positive nerves on basal artery(BA) and bilateral posterior cerebral artery(PCA), internal carotid artery(ICA), and anterior cerebral artery (ACA), obviously decreased. After bilateral operation, the positive nerve fibers in all arteries except ACA disappeared. There were no significant difference between group BⅠ and BⅡ; CⅠ and CⅡ.Conclusion There were nitrergic nerve fibers in all major cerebral arteries, and the density of positive nerve fibers in the anterior circulation of the cerebral artery was higher than that of posterior one. Different cerebral arteries have different origins of nitrergic nerve. The nitrergic nerve in BA, PCA and ICA completely originated from ipsilateral pterygopalatine ganglia; the nitrergic nerves of MCA were completely originated from ipsilateral pterygopalatine ganglion; ACA have more sources of nitrergic nerves other than bilateral pterygopalatine ganglia. Nasociliary nerve from trigeminal ganglion did not involve in the origins of nitrergic perivascular nerves in rat cerebral arteries. [
