Objective To investigate the metabolism characteristics and the potetial biomarker candidates of osteonecro?sis of the femoral head (ONFH) using metabolomic technology. Methods The femoral head specimens from 23 ONFH patients (25 necrotic femoral heads) and 18 normal femoral heads from femoral neck fracture patients were collected for histopathological examination to confirm the diagnosis of all samples. All the metabolites of bone trabecula were extracted for ultra-high perfor?mance liquid chromatography-MS/MS analyzed. The measured variables was pretreat, and PCA (principal component analysis), PLS?DA (partial least squares?discriminant analysis) and OPLS?DA (orthogonal?partial least squares?discriminant analysis) models were employed to confirm the difference between these two groups after UPLC?MS/MS (ultra?high performance liquid chromatogra?phy?mass spectrometry/mass spectrometry) analysis. At last, the differential variables were screened out by PLS?DA and variate analysis (Kruskal?Wallis H test). The changed metabolites were confirmed by MS and MS/MS aligned in HMDB (human metabolo?mic database) and Massbank. The changed metabolites with the most obviously changed peak abundance, D?arginine, L?proline and L?glutamine, were picked out as the potential diagnostic biomarkers. After binary logistic regression analysis, the combined biomarkers candidates were further analyzed by receiver operating characteristic (ROC) curve to evaluate the significance of the combined biomarkers. Results Significant distinction of metabolites expression mode can be seen in PCA, PLS?DA and OPLS?DA models scoring plots between ONFH and control groups. Twelve changed metabolites in ONFH bone trabeculas were con?firmed by multi?variate statistical analysis and variate statistical analysis. Compared with the femoral neck fracture patients, the in?creased metabolites included D?arginine, L?proline, L?glutamine, creatine, uracil, uridine, LysoPC(20∶4(5Z, 8Z, 11Z, 14Z)), Ly?soPC(16∶0), PC(20∶1(11Z)/18∶3(6Z, 9Z, 12Z)) and PE(P?16∶0e/0∶0). The decreased metabolites were reticulataxanthin and β?cryptoxanthin. According to the change fold of peak abundance and variable weight projection in PLS?DA, the most obviously dif? ferential metabolites were picked out as the biomarker candidates of ONFH. The potential biomarkers candidates were identified as D?arginine, L?proline and L?glutamine. The area under the curve of D?arginine, L?proline and L?glutamine ROC were 0.873, 0.712 and 0.862. The area under the curve of ROC was 0.946 after combining D?arginine, L?proline, L?glutamine using binary lo?gistic regression analysis. Conclusion PCA, PLS?DA and OPLS?DA models were used to find out the differential variables in the metabolites of bone trabeculas in ONFH and femoral neck fracture patients. Twelve metabolites were identified by MS/MS, and 3 obviously changed metabolites, D?arginine, L?proline, L?glutamine, were indicated as biomarker candidates. These 3 obviously changed metabolites showed a good diagnostic significance.

OBJECTIVETo examine the oral health status among the orphan children and adolescents of Chongqing and assist in planning of the oral health programs.

METHODSAccording to the third national oral health investigation of epidemiology, the dental caries, gingival bleeding and calculus was examined among 317 orphan living in Chongqing, by cluster sampling. The statistical software SPSS 17.0 was used for the data analysis.

RESULTSIn primary and permanent teeth, the prevalence of dental caries and mean DMFT (dmft) were found to be 50.00%, 1.94 +/- 2.81 and 39.53%, 0.90 +/- 1.38. There were no significant difference between female and male (P>0.05). But there was significant difference of the prevalence of permanent tooth caries between the age group under 12 (include 12) and above 12 (P < 0.05). It was also found that 35.25% of the orphan children and adolescents had caries in the first permanent molar, and there was significant difference between female and male (P < 0.05). Neither of the caries teeth above was treated nor the healthy teeth were sealed. The prevalence rate of gingival bleeding was 78.22%, and the calculus rate was 67.66%.

CONCLUSIONThe oral status of the orphan is poor, and this community has experienced a low utilization of preventive or therapeutic oral health services. In the future work, orphans should be considered as a priority group when make plans for oral health care.

Objective To study effect of high ilioinguinal approach in treatment of acetabular fractures involving quadrilateral plate. Methods 28 cases of acetabular fractures were randomly divided into two groups according to admission time. 16 patients in the observation group were given high ilioinguinal approach operation. 12 patients in the control group were treated with traditional ilioinguinal approach op-eration. Operation condition, fracture reduction, the hip function recovery and postoperative complications of the two groups were compared. Results The amount of bleeding, the length of incision, operation time and operation conditions of the two groups had no significant differ-ence (P>0. 05). The satisfactory fracture reduction rate of observation group was higher than the control group (P<0. 05). Hip function score of observation group was significantly higher than that of the control group (P<0. 05). In observation group, the excellent rate of hip joint function was better than that of the control group (P<0. 05). The incidence rate of complications in the observation group and the con-trol group were 12. 50% and 16. 67% respectively, and there was no significant difference between the two groups (P>0. 05). Conclusion High ilioinguinal approach can improve the fracture reduction effect, effectively improve the hip joint function in patients, and it has higher security which is a kind of ideal treatment approach for acetabular fractures involving quadrilateral plate.

BACKGROUND:A variety of cel lines participate in the construction of animal models of osteosarcoma. OBJECTIVE:To compare the abilities of subcutaneous tumorigenesis of human osteosarcoma cel lines MG63, U2OS and 143B in nude mice, and to establish the basis for experimental studies on osteosarcoma. METHODS:A total of 18 nude mice were randomly divided into MG63, U2OS and 143B groups. The back of nude mice was subcutaneously injected with MG63, U2OS and 143B cel lines in corresponding groups, and the process of tumorigenesis was observed. RESULTS AND CONCLUSION:MG63 and U2OS could not induce subcutaneous tumorigenesis in nude mice. Tumors were observed after injection with 143B cels for (6±1) days, with the tumor formation rate of 100% (6/6). The tumor grew very fast. The mean volume of tumors was (3 475±1 544) mm3 at 2 months. The survival time of nude mice burdened with tumors was (68±10) days. Hematoxylin-eosin staining revealed that in tumor tissue, cancer cels formed nest shape, nuclei were big and darkly stained, and split mostly. These results suggested that 143B cel line could wel induce subcutaneous tumorigenesis, which could be used for animal research of osteosarcoma.
