BACKGROUND:Developmental dislocation of the hip is a type of adult hip dysplasia, including Crowe III and IV type; the type of dislocation of the hip is a severe prognosis. Total hip replacement is clinicaly used for the complex reconstruction of acetabulum. For injured acetabulum, autologous bone graft is effective to reconstruct acetabulum structure, provides good coverage and stability for the acetabulum. Postoperative combination with effective exercise can ensure the recovery of acetabulum function. OBJECTIVE:To analyze the correlation of prosthesis position selection during total hip replacement with clinical short- and middle-term effects of Crowel III and Crowel IV hip dislocation. METHODS:Clinical data of 28 cases of dysplasia and dislocation of the hip joint combined with severe osteoarthritis, who were treated in the Department of Joint Surgery, the Second Affiliated Hospital, Inner Mongolia Medical University from December 2011 to December 2012, were retrospectively analyzed. Al patients received total hip replacement. Implant was biological artificial total hip joint prosthesis. During 2-year folow-up, patients were rechecked by imaging regularly to analyze the imaging changes of acetabulum prosthesis position and bone graft fusion. Harris hip score was used to assess the recovery of hip function. The correlation of prosthesis position and short- and middle-term effects was analyzed. RESULTS AND CONCLUSION: The filing rate of medulary cavity of prosthesis was above 75%. The initial position was fixed and stable. The stability rate of femur-prosthesis interface reached 100%. Compared with pre-replacement, hip function was significantly improved at 6 months post surgery (t=25.55, 9.07;P < 0.05). These results indicate that total hip replacement for Crowel III and Crowel IV hip dislocation can effectively reconstruct the acetabulum, recover hip function, and stabilize prosthesis. Total hip replacement is characterized by good filing rate, high stability of femoral prosthesis interface, and stable initial fixation. The clinical repair effect is strongly associated with the position of the prosthesis.

Objective To investigate the organic pollutants in the contaminated water irrigation area soil and to study the lipid peroxidation effect of the pollutants on mouse. Methods The organic pollutants of the polluted irrigation soil and control soil were extracted using the supersonic oscillator. The ingredients of the organic pollutants were measured by the GC-MS spectrum. The 40 sanitary Kunming mice were randomly divided into five groups: the dimethylsulfoxide control group,low dose group of control soil,high dose group of control soil,low dose group of polluted soil,high dose group of polluted soil. The administered doses of the low and high dose groups were 25.5 g dry soil/kg body weight per day by oral for two weeks. The activities of T-SOD,GSH-Px and the content of MDA in serum of mice were determined. Results Phenanthrene,yrene,diphenyl,fluorene,naphthalene,dimethyl-naphthalene,2,3,6-trimethyl-naphthalene,anthracene,dimethyl-anthracene,1,4-dimethyl-anthracene,fluoranthene,4-methyl-pyrene,dibenzothiophen,4-methyl-dibenzofuran,dibenzofuran,butylated-hydroxytoluene,dodecane,neopentyl-cyclohexane,trimethyl-heptane,1,2-dimethyl-cyclohexanimine,butethal were detected in the polluted irrigation soil and their levels were 14.3,2.1,1.3,1.1,0.8,1.3,0.4,2.9,7.2,2.3,9.1,0.2,0.4,1.4,1.7,0.37,0.9,0.11,0.02,0.02 and 0.13 mg/kg respectively in the polluted irrigation soil. Trimethyl-heptane,dimethyl-heptane and 1,2-dimethyl-cyclohexanimine were detected,and their levels were all 0.01 mg/kg in control soil. Compared with the solvent of dimethylsulfoxide group,the activities of T-SOD and GSH-Px of the high dose group of control soil and two dose groups of polluted soil all decreased,the differences were all significant(P0.05). Conclusion The soil has been contaminated with organic pollutants in the investigated area and the soil extract may produce a certain effect on lipid peroxidation in mice.

Objective·To explore the biologic effect and mechanism of adenanthin (Aden) on multiple myeloma (MM) cells. Methods·MM cells, H929 and U266 were treated with various dose of Aden for different time, and the density and viability of MM cells were detected by trypan blue exclusion assay. After H929 and U266 cells were treated with various dose of Aden for 24 hours, cell growth inhibition was examined by CCK8 assay, and cell apoptosis was examined by AnnexinV-APC/PI staining assay. Apoptosis related proteins, NF-κB signaling pathway associated proteins and the NF-κB regulated proteins were detected by Western blotting. The effect of Aden on the thermal stability of IKKβ protein was determined by CETSA assay. Results·Trypan blue exclusion results showed that Aden inhibited cell growth and reduced cell viability in concentration and time dependent manners. U266 was more sensitive than H929 when exposed to the same concentration of Aden. The CCK8 results showed that Aden inhibited the growth of H929 and U266 cells in a concentration dependent manner. Flow cytometry results suggested that Aden induced a low apoptosis rate of MM cells. Moreover, cleavage of caspase3 and PARP were detected in U266 cells but not in H929 cells. CETSA assay indicated that Aden decreased the thermal stability of IKKβ. Expression of p-p65 and p-IκBα proteins decreased in MM cells treated with Aden. Conclusion·Aden significantly inhibits MM cell proliferation by inhibiting NF-κB activation through interacting with IKKβ. Aden has little effect on apoptosis of MM cells.

Objective To establish symptom check list 90 (SCL-90) norm for Chinese oilmen.Methods Based on multi-level stratified or cluster sampling technique,a total of 13 472 oilmen from China National Petroleum Corporation completed a sampling survey on measured data of SCL-90.Student's t test and one-way analysis of variance (ANOVA) were used to compare gender,age,education level and marriage status.Results All the reliability coefficients were ＞ 0.8 and P for validity test was ＜ 0.05.In comparison with SCL-90 norm of healthy Chinese adults in 1986,the interpersonal sensitive (1.5 ± 0.6)and paranoia (1.4 ± 0.6) of oilmen were lower (t≤-4.17,both P ＜ 0.05),although other 8 factors showed higher scores (t ≥ 2.4,all P ＜ 0.05).Oilmen also had lower scores for each item than Chinese army men (t ≤-2.62,all P ＜ 0.05).Total score (131.4 ± 47.7),interpersonal sensitive (1.4 ± 0.6),hostility (1.5 ± 0.6),paranoia (1.4 ± 0.6) and psychosis (1.3 ± 0.5) of females were lower than those of males (t≥2.53,all P ＜ 0.05).30-39 years group indicated the highest scores for each item (all P ＜0.05),while 17-29 years group got the lowest (all P ＜ 0.05).Meanwhile,the subjects whose education level was equate to or lower than high school or those got married were found to have the highest scores (all P ＜ 0.05).Conclusions Our data show better item differentiation,reliability and validity of SCL-90.SCL-90 norm may be used for mental health assessment of Chinese oilmen.
