RESUMO
BACKGROUND: The Kazakhs mainly live in the Yili Kazakh Autonomous Prefecture in northwestern Xinjiang. About 80% of the Kazakhs live in the areas of Yili, Tacheng, and Altay. To fully understand the physical characteristics of Kazakhs, a viviperception and head and face measurements of Kazakhs at the age of 20 and 86 were performed in Gilgelang Township, Gongliu County, Xinjiang. OBJECTIVE: To grasp the morphological traits in the head and face of Kazakh adults in Xinjiang. METHODS: Thirty-one head-face indexes of 422 Kazakh adults (219 males and 203 females) from Jiergelang county, Xinjiang were investigated. Twelve physical indices of the head and face were calculated. RESULTS AND CONCLUSION: In the Kazakh group, the incidence of eye fold of the upper eyelid was 92.7%; the rate of mongoloid fold was 9.9%; the appearance rates of flat and vertical types was 6.6% and 93.4%, respectively; the appearance rates of convex, concave and straight nasal profiles were 7.8%, 36.5% and 55.7%, respectively; the appearance rates of oblique, vertical and horizontal nostril shapes were 69.5%, 20.8% and 9.7%, respectively; the appearance rates of the chin of straight type and convex type were 68.2% and 31.8%, respectively; the appearance rates of earlobe type and non-earlobe type were 96.7% and 3.3%, respectively; the appearance rates of forehead hairline and non-forehead hairline were 72% and 28%, respectively; the appearance rates of straight hair and curly hair were 99.1% and 0.9%, respectively. Most of Kazakh males have dolichocephaly and hyperdolichocephaly (81.7%, 52.5%), hypsicephaly (93.6%), aerocephaly (84%), hyrerleptorrhiny (98.2%), and hypercuryen (74%). Kazak females most have dolichocephaly and hyperdolichocephaly (76.4%, 55.7%), hypsicephaly (97%), aerocephaly (84%), hyrerleptorrhiny (98.2%), and hypercuryen (74%). The head-face characteristics of Kazak population belongs to the North Asian type of Mongoloid．.
RESUMO
OBJECTIVE@#To observe reinforcing effect of calcium sulfate cement (CSC) bovine bone morphogenetic protein (bBMP) on vertebral in the rabbit model of osteoporosis.@*METHODS@#A total of 48 New Zealand white rabbits were randomly divided into group I (blank control group), group II (CSC injection group), group III (CSC/bBMP injection group) and control group. White rabbit osteoporosis model was established rapidly by using castration method+methylprednisolone candidate. After modeling, groups II, III were given corresponding vertebral body injection material, and 4 animals were sacrificed respectively at 24 h, 6 weeks, 12 weeks after vertebral plasty. Tissue pathological status, vertebral mineral density and vertebral body bone mechanical strength were observed.@*RESULTS@#Vertebral body structure form was normal in the groups II and III. Trabecular bone coarsens, connection and repair were observed in micro fracture and bone defects, bone trabecular connectivity was superior to group I significantly; vertebral body compression strength in the group I was on the decline, vertebral compression strength in the groups II and III was on the rise, the largest vertebra. Postoperative BMC and BMD in groups II and III were increased, and significantly higher than group I after 6 weeks (P<0.05), BMC and BMD in group III after 12 weeks were higher than the other three groups.@*CONCLUSION@#Compound bBMP CSC has good bone induction. It can improve the three-dimensional construction effect for osteoporosis vertebral trabecula, and can significantly improve the vertebral strength, as a vertebral packing material with good application prospect.
