With the increasing life span of the population and the increasing proportion of the elderly population, the elderly with osteoporosis are prone to hip fractures, which brings heavy economic burdens to the family and society. The progress in predicting hip fractures from the aspects of the proximal femur geometry, bone mineral density (BMD), fracture risk assessment tool (FRAX) and finite element analysis (FEA) based on computed tomography (CT) imaging was reviewed, in order to understand the influencing factors of fracture risk, improve the accuracy of hip fracture risk prediction for the elderly, detect the high fracture risk group at an early stage, and hence to reduce the occurrence of fractures with appropriate preventing measures, and provide theoretical references for the prevention and treatment of hip fractures.

Objective To investigate the structure and mechanical properties of pods after dehydration and the biomechanical mechanism of spreading pod seed injection due to torsion crack. Methods The layered pods, the cell size and direction at different cellular layers were analyzed by histology, microstructure observation, mechanical property test and high-speed photography. The process of pod ejection was observed, and the principle of pod ejection was summarized. Results The ejection of pods started from the crack of the bottom, and cracked gradually from the bottom to the top. The cell arrangement of two parts of the same pod was opposite. Each pod was divided into 4 layers wherein the first exterior layer and the middle layer were orthogonal to each other. There was a layer of cells between the first exterior layer and the middle layer, of which the cell wall was broken. In the process of dehydration, fibers in the outer layer shrank and fibers in the middle layer stretched. Conclusions Pod fiber will be contracted in the orthogonal direction after dehydration to accumulate elastic performance and generate pre-stress, and finally the pod is cracked to release the pre-stress.

Objective To study effects of different types of high-impact exercises on the increment of bone mineral density (BMD) and bone mineral content (BMC) . Methods Thirty-nine male volunteers, including 13 hoopsters, 13 paratroopers, and 13 common college students as the control, were recruited and divided into two subgroups (subgroup 1:20-22 years old; subgroup 2:23-25 years old). Their BMDs and BMCs on calcaneus, first through fifth metatarsus, hip, and lumbar spine (L1-4) were evaluated. Results The BMC of calcaneus, the first and second metatarsals, total lumbar spine, and total hip in the hoopster group was significantly higher than that in the control group and paratrooper group. The hoopster group obtained statistically higher BMD at the lumbar spine, hip, and femoral neck than the other two groups. However, the BMCs and BMDs of the paratrooper group and control group had no significant differences at almost all measured anatomical locations. Conclusions BMC and BMD are not always in positive correlation with vertical ground reaction forces during normal exercises. Compared with parachuting training, playing basketball as a kind of variable load exercise can effectively increase BMC and BMD, and is more beneficial for reducing the risk of osteoporotic fracture.

Objective: To investigate clinicopathological features of carcinoma showing thymus-like elements (CASTLE) in the head and neck regions. Methods: Clinicopathological data of 7 patients with CASTLE in the head and neck regions were retrospectively reviewed.Immunohistochemical staining and in situ hybridization for EBER were performed. BRAF^V600E mutation was examined by ARMS method in 6 cases. Results: There were 5 females and 2 males with age between 49 and 78 years (average of 65.6 years). All tumors were solitary nodular lesions with an infiltrative border, including 6 intrathyroid tumors and 1 extrathyroid tumor in the laryngeal pharynx.The tumors were 1.7-4.1 cm in diameter (average of 3.0 cm). Four cases demonstrated lymph node metastasis.All patients were alive without metastasis during follow-up, except one consultation case (with FNA sample) developed recurrence at the primary site. The cases showed different immunoreaction to CD5, diffuse immunoreaction with p63, CK5/6 and CD117, but negative staining for TTF1, TG and calcitonin. One case showed positive immunoreaction with Synin less than 30% tumor cells. The Ki-67 labeling index was between 3% and 90%. No BRAF^V600E mutation and EB virus infection were detected. Conclusions Extrathyroid CASTLE involving laryngeal pharynx shows the similar morphological and immunohistochemical features with intrathyroid CASTLE.Immunohistochemical markers of CD5 and CD117 are helpful in the diagnosis. Ki-67 labeling index can be high in CASTLE, especially in lymphoepithelioma type. CD5-negative CASTLE may have neuroendocrine differentiation. BRAF^V600E mutation and EB virus may not be involved in the carcinogenesis of CASTLE.

[ ABSTRACT] AIM:To evaluate the effects of 1α, 25-dihydroxyvitamin D3 on T helper cell 17 ( Th17 cells) and its related cytokines in a mouse model of corneal allograft transplantation.METHODS:C57BL/6 mice were transplanted with corneal grafts from BALB/c mice and treated intraperitoneally with 1.0μg 1α, 25-dihydroxyvitamin D3 or soybean oil every other day after operation.The transparency of the corneal grafts was evaluated for potential rejection signs by slit lamp biomicroscopy and histopathology.The expression levels of IL-17, RORγt and IFN-γin the spleen were measured by real-time PCR.Moreover, the protein expression of RORγt and IL-17 in the peripheral blood was analyzed by Western blotting. IL-17 and IFN-γin peripheral blood were measured by flow cytometry.RESULTS:1α, 25-dihydroxyvitamin D3 signifi-cantly inhibited the rejection of the corneal allograft and reduced the numbers of inflammatory infiltrates in the corneal graft. In the spleen, 1α, 25-dihydroxyvitamin D3 treatment reduced the expression levels of IL-17, RORγt and IFN-γ.In the pe-ripheral blood, 1α, 25-dihydroxyvitamin D3 treatment downregulated the expression levels of RORγt, IL-17 and IFN-γ. CONCLUSION:The effects of 1α, 25-dihydroxyvitamin D3 on suppressing corneal transplantation-induced allograft rejec-tion in mice are closely associated with its modulation on IL-17 and related cytokine RORγt.

Background Interleukin (IL)-1a-889C/T,IL-1β-S11C/T,+ 3962C/T and IL-1Ra-2 are different morphology of single nucleotide of interleuki-1 (IL-1).The potential relationship of IL-1 polymorphisms with Beh(c)et disease has been studied in several populations and groups.However,study outcomes are controversial for a long duration.Objective This Meta-analysis was to determine whether the IL-1 gene polymorphisms is associated with the pathogenesis and development of Beh(c)et disease.Methods The literature of the assoiation between IL-1 polymorphisms and Beh(c)et disease was retrieved from Medline,EMBASE,Cochrane Library,Web of knowledge,Google Scholar,Wanfang and CNKI databases.All the published original articles (case-control studies) were reviewed with the deadline May 31,2013,and the languages were limited to English and Chinese.Included reports were evaluated based on Newcastle-Ottawa Scale (NOS) score.The potential influence of IL-1α-889TT gene,IL-1β-3962C,IL-1β-511T and IL-1Ra-2 polymorphisms on Beh(c)et disease were analyzed.RevMan5.0,the Cochrane collaboration software program,was used to prepare and complete this review.The effect size was assessed using fixed effect model in the index with lower heterogeneity (I2 ＜50％) or randomized effect model in the index with higher heterogeneity (I2＞50％).Results The literature search resulted a total of 370 cases-controlled studies,and 7 studies met the included criteria,with the NOS scores ≥ 8.The total patients were 499 and normal controls were 708.Meta-analysis was performed on several populations.Overall,the polymorphisms of IL-1β-3962C allele increased the susciptibility of Beh(c)et disease (OR =1.41,95％ CI:1.06-1.88,P =0.02),and IL-1α-889TT genotype reduced the risk of Beh(c)et disease (OR =0.61,95 ％ CI:0.40-0.92,P =0.02).However,There was no significant association between variants of IL-1β-511T allele (OR =0.84,95％ CI:0.58-1.23,P=0.38) or IL-1RA-2 allele (OR =1.25,95％ CI:0.50-3.14,P=0.63) and Beh(c)et disease susciptibility.Conclusions These results suggest that Beh(c)et disease is associated with the IL-1 gene polymorphisms at the locations α-889C/T and β-3962C/T.A larger sample size clinical data still are need to confirm this conclusion.
