ABSTRACT

【Objective】 Until now, most clinical and basic studies on Kashin-Beck disease (KBD) have focused on the visible deformed extremities, and there is a lack of reports concerning their spinal features, especially for the atlantoaxial joint. The purpose of this study was to determine the prevalence and radiographic features of atlantoaxial dislocation (AAD) in KBD in adult patients. 【Methods】 The prevalence and radiographic features of AAD were determined by the basic information collected, clinical symptoms, and lateral and dynamic plain radiography in 111 KBD patient and 120 non-KBD participants. In the KBD group, AAD and non-AAD patients were compared in age, gender, height, weight, BMI, smoking history, chronic history, disease duration and grade of disease so as to identify the related factors of the occurrence of AAD. 【Results】 Symptoms at the neck or neurological manifestations were present in 17.5% (21/120) in the non-KBD population and 39.6% (44/111) patients with KBD. AAD case was not detected in the non-KBD population, while in 16.2% (18/111) of KBD patients in the endemic area. The prevalence was higher in the KBD patients than in the non-KBD population, and there was a significant difference in the detection rate of AAD between the two groups (χ2=21.10, P<0.001). Plain radiography demonstrated that there were 10 (55.6%) cases with separation of the odontoid process and the other 8 (44.4%) cases with hypoplasia of odontoid process. Anterior AAD was noted in 12 (66.7%) patients and posterior AAD in 6 (33.3%) cases based on the displacement direction, while 16 (88.9%) cases were reducible and 2 (11.1%) cases were irreducible on the basis of the reducibility. Comparing the 93 patients with non-AAD KBD patients and 18 patients with AAD patients, there was no significant difference in age, sex, BMI, history of medical disease or smoking (all P>0.05). There were significant differences in height, weight, disease duration and grade of disease between AAD and non-AAD patients (all P<0.05). 【Conclusion】 KBD can cause the occurrence of atlantoaxial dislocation by inducing separation or hypoplasia of the odontoid process. This research may provide clinical evidence for screening, earlier prevention and treatment of atlantoaxial dislocation in adult KBD patients.

ABSTRACT

ABSTRACT:Objective To study the expressions of adrenomedullin (ADM)andβ-catenin in human osteosarcoma of different differentiation grading and their clinical significance.Methods We chose 33 cases of human osteosarcoma with different pathological grading (14 cases of high differentiation grading and 1 9 cases of low grading)and 10 cases of human osteochondroma to detect the expressions of ADM protein,total (T)β-catenin and phosphorylated (P)β-catenin using immunohistochemical method. Results The expression of ADM was detected in the cytoplasm.In osteosarcomas of higher and lower differentiation grading,the positive rate of ADM was 57.1% (8/14)and 100% (1 9/1 9),respectively,with significant differences (P =0.0030.05).The expression of P-β-catenin was detected in the cytoplasm.In osteosarcomas of higher and lower differentiation grading,the positive rate of P-β-catenin was 35.7% (5/14)and 78.9% (1 5/1 9),with a significant difference (P =0.029 0.05 )or between T-β-catenin and P-β-catenin (P = 0.052 > 0.05 ).Conclusion The expressions of ADM and P-β-catenin proteins and the different distributions of expression of T-β-catenin protein in cytoplasm and/or nucleus are important indicators for judging the pathological grading of osteo-sarcoma.

ABSTRACT

Objective To observe the effect of silencing the expression of ADM using RNA interfering technique on the expression ofβ-catenin and terminal differentiation of osteosarcoma cells.Methods After the intervention of 0 h,48 h and 72 h by ADM siRNA,we observed the change of distribution ofβ-catenin in F5M2 using immunocytochemistry staining.The expression levels of total and phosphorylatedβ-catenin and GSK3βwere detected by Western blot after the intervention by ADM siRNA.The F5 M2 cells treated with ADM siRNA were subjected to HE staining,alkaline phosphatase (ALP)assay and immunocytochemistry staining to investigate the biological effects of ADM siRNA on the morphology and terminal differentiation of F5M2 cells.Results After the intervention of 0 h,48 h and 72 h by ADM siRNA,the distribution ofβ-catenin was transferred from the cytoplasm to the nucleus.ADM siRNA downregulated the expression level of P-β-catenin and upregulated P-GSK3βdetected by Western blot.HE staining revealed that the configuration of F5M2 had undergone restorational changes similar to those of normal cells after ADM siRNA treatment.ALP assay and immunocytochemistry staining showed that the expression of the earlier and later molecular biomarkers of terminal differentiation,including ALP and osteocalcin were strongly positive.Conclusion Silencing the expression of ADM can activateβ-catenin to transfer to the nucleus from the cytoplasm,and induce osteosarcoma cells to make terminal differentiation through activatingβ-catenin signaling pathway.

ABSTRACT

Objective To observe the clinical effect and safety of percutaneous kyphoplasty (PKP) on osteoporosis vertebral compres-sion fractures (OVCF) in elderly. Methods From January, 2014 to May, 2015, 88 patients with OVCF treated with PKP were retrospective studied. Visual Analogue Scale (VAS) and Oswestry Dysfunction Index (ODI) were used to evaluate the pain and quality of life, and the ky-photic angle (Cobb's angle) and anterior vertebral body height were recorded before operation, one week after operation and the last fol-low-up. The cement leakage and its effect on nerve function were recorded. Results Bone cement leakage was found in eleven patients, in which two in pedicle, three in venous leakage, three in intervertebral disc and three in vertebral posterior. Nerve root symptoms appeared in one patient, who was treated with decompression. The scores of VAS and ODI, and the Cobb's angel were significantly lower (t>29.518, P35.173, P<0.001) one week after operation and the last follow-up than be-fore operation. Conclusion PKP is safe and effective for OVCF in elderly. It can efficiently reduce the pain, correct kyphotic deformity and improve the quality of life.
