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.

Objective To investigate the curative effect of transpedicular screw fixation plus percutaneous vertebroplasty (PVP) for treatment of severe thoracolumbar osteoporotic vertebral compression fractures (OVCF).Methods Twenty-one patients with severe OVCF presenting to our hospital from July 2012 to May 2015 were analyzed retrospectively.There were nine male and twelve female patients,aged 50-78 years (mean,68.8 years).The level of injury was T1 1 in four patients,T12 in six,L1 in five,L2 in three,L3 in two and L4 in one.Time between injury and surgery was 2-16 d (mean,7.5 d).All patients underwent pedicle screw fixation at the injured level combined with PVP.Visual analogue scale (VAS) was used for evaluation of lower back pain after operation,Oswestry disability index(ODI) for lower back function,lateral thoracolumbar film for Cobb angle and anterior vertebral height compression ratio,and American Spinal Injury Association (ASIA) score for spinal cord nerve function.Postoperative complications were recorded.Results All patients were followed up for 12-21 months [(15.7 ± 2.9) months].Postoperative studies showed significant differences in VAS [(2.9 ± 1.1) scores],ODI [(30.8 ± 7.5) ％],Cobb angle [(21.5 ± 7.3) °] and anterior vertebral height compression ratio [(44.3 ± 13.9) ％] compared to the preoperative measures (P ＜ 0.05).Cobb angle and anterior vertebral height compression ratio at the final follow-up were (23.4 ± 7.7)° and (49.1 ± 13.7)％ respectively,and had no significant differences from the postoperative measures (P ＞ 0.05).According to the ASIA score,eight patients with neural function injury had one to two level recovery at the final follow-up.Asymptomatic cement leakage occurred in seven patients after operation.There was no internal fixation breakage at the final follow-up.Conclusions Transpedicular screw fixation plus PVP can not only restore the height and strength of the injured vertebrae and correct kyphotic deformity,but also relieve low back pain and improve function of the spine.Therefore,the technique is a safe,reliable and effective surgical treatment for severe thoracolumbar OVCF.

Objective To research the endometrial receptivity by established the endometriosis rat model in intimal window period.Methods The autologous endometrial tissues of 22 sexually mature SD rats were transplanted into the homonymy abdomi-nal wall and offside uterine mesometrium.After four weeks,we randomly dissected two rats and observed the growth of etopic en-dometrium.The EMs rats were mated with male rats in the same cage and vaginal plug was observed in the next day.The histomor-phology of eutopic and ectopic endometrial was observed in the fifth day of pregnancy.Results Ectopic endometrium was grown in the abdominal wall and mesometrium,which formed a small bulge cystic mass in 20 rats.All foci was showed adhesion to the sur-rounding tissues in a different extent.In the light microscope,the morphology of ectopic endometrial was as the same as nomal en-dometrium.The establishment of the endometriosis rat mode is successful.Vaginal plug was positive the next day.Nonoperative side uterine was full of fluid in the fifth day of pregnancy.Eutopic and ectopic endometrium were in the secretory phase..Conclusion It is a successful method to establish a rat model of endometriosis by autotransplantion of endometrium.The endometrium of EMs model rats is in embryo implantation window period,and it provides a convenient model for studying endometrial receptivity.
