Objective To screen the serum protein molecular markers of postmenopausal osteoporosis by the proteomicsanalysis using Tandem Mass Tag (TMT) combined with liquid chromatography-tandem mass spectrometry (LC-ESI-MS/MS).Methods 20 serum protein samples were recruited (10 cases of postmenopausal patients with osteoporosis and 10 cases of postmenopausal women without osteoporosis)and the high abundance ratios protein was removed,differentiation protein was extracted and labeled with TMT reagent.Then,mass spectrometric detection,data analysis of differentially expressed proteins,and analysis of biological information were carried out.Results 87 significantly differentially expressed proteins were screened from the differentiated protein expression profile by LC-ESI-MS/MS combined with TMT labeling.While 50 proteins were up-regulated,and 37 proteins were down-regulated.Differentially expressed proteins were analyzed by GO annotation,these proteins are mainly involved in 15 kinds of biological processes,7 kinds of cellular component,6 kinds of molecular function.RAB7A,TSP1,GAS6,SPP24 were screenedas candidate proteins which were related to mechanism of bone remodeling of osteoporosis.By STRING 10.0 protein interaction network analysis tools,RAB7A,TSP1,GAS6 were located in the center of the interaction network.SPP24 was located at edge of the network,but it is directly related to the protein BMP-2 of bone remodeling.RAB7A,TSP1,GAS6,SPP24 may be associated with the pathogenesis of postmenopausal osteoporosis.Conclusion These results provide that the proteomics analysis by using TMT coupled with LC-ES1-MS/MS was a feasible method for screening the molecular biomarkers.It suggests that RAB7A,TSP1,GAS6 and SPP24 may be useful biomarkers which can be used both in diagnosis and treatment of postmenopausal osteoporosis.

Objective To study the expression of inflammatory factors in the saliva and the stability of implants after implant denture repair in pa-tients with dysplasia of the dentition defect ,and to analyze the prognosis of patients with lipid metabolic disorder. Methods The dentition defect patients with lipid metabolism disorder were selected as the experimental group. Patients with lipid defect were selected as the control group. Saliva was collected before implantation,1 month and 3 months after implantation. ELISA method was used to detect IL-6,IL-1βand TNF-α. Osstell ISQTM radio frequency analyzer was used to detect the stability of the implants and the periodontal status was detected by Florida probe. Re-sults There were no significant differences in the depth of implant probing(PD),bleeding index(BI)and ISQ between the two groups by radio frequency analyzer(all P>0.05). The levels of IL-6,IL-1βand TNF-αin the pre-implantation,1 month and 3 months after implantation were sig-nificantly higher than those in the control group(all P<0.05). The levels of IL-6,IL-1βand TNF-αin the experimental group were significantly higher than those in the control group before planting(all P<0.05) 3 months after planting,there were no significant differences of IL-6,IL-1β, and TNF-αbetween the experimental group and control group(all P>0.05). Conclusion The patients with dyslipidemia after implantation have good implant stability as those with normal blood lipid ,and the patients with dyslipidemia can also obtain good prognosis.

BACKGROUND:Due to good function and aesthetic effect, implant dentures become prevalent in osteoporotic patients with missing teeth. However, whether osteoporosis is a contraindication of dentures as wel as effects of osteoporosis on the bone-implant integration have been not ful y understood.
OBJECTIVE:To compare the levels of alkaline phosphatase, bone mineral density and implant stability in patients with osteoporosis and non-osteoporosis, and to explore whether the osteoporotic patients can achieve good prognosis. METHODS:Forty patients undergoing implant dentures in the Department of Prosthodontics, the First Affiliated Hospital of Xinjiang Medical University since February 2015 were enrol ed, and al otted to experimental (osteoporosis) and control (non-osteoporosis) groups (n=20 per group).
RESULTS AND CONCLUSION:The levels of salivary alkaline phosphatase, bone mineral density and initial implant stability in the experiment and control groups both were lower than those before surgery. There were significant
differences in the implant stability quotient at 1 and 3 months and immediately after implantation between groups. These results indicate that osteoporotic patients undergoing implant surgery can achieve a good prognosis that is similar with non-osteoporosis ones.

We designed a locator for puncture under CT examination.Thirty-three patients of both sexesaged 16-76 yr weighing 46-80 kg undergoing bilateral thoracic or lumber sympathetic nerve block under CT examination were enrolled in this study.One side was punctured under the guidance of the locator,while the other side was punctured by conventional technique.The time consumed during puncture,CT scan adjusting time,the deviation of the needle from the targets and the incidence of puncture complications were recorded.The results showed that compared with the conventional technique,with the locator the time consumed during puncture was significantly shorter,the number of attempts and the deviation of the needle from the target were significantly reduced.The procedure was successfully performed on both side in all patients without serious complications such as hemothorax and pneumothorax.

RESULTSAll the ten flaps survived and the appearance was good.

CONCLUSIONThe method is easy except for the necessity of performing standard microvascular surgery. The flap is a good option for repairing fingertip defects.

Objective To analyze the effects of different therapies on patient survival,to explore the related prognostic factors in elderly patients with advanced gastric cancer,and to provide recommendations for the treatment of such patients.Methods Retrospective analysis was conducted on 146 elderly patients with advanced gastric cancer hospitalized from January 2009 to October 2013 in Yixing People's Hospital of Jiangsu Province.Detailed clinical data were recorded,and patients were followed up during the total survival time.Univariate analysis with the Log rank test and multivariate analysis with the COX proportional hazard model were utilized to examine the related prognostic factors in elderly patients with advanced gastric cancer.Results The 1-,2,3-year survival rates of t46 elderly patients with advanced gastric cancer were 33.6 ％,11.0 ％,and 2.1 ％,respectively,and the median survival time was 10.3 months.The Log-rank test showed that Karnofsky (KPS) score,differentiation degree,number of metastatic sites,malignant serous effusion,chemotherapy,and traditional Chinese medicine (TCM) were associated with the prognosis of elderly patients with advanced GC (all P＜0.05).Multivariate analysis by the COX proportional hazard model showed that KPS score (HR=1.575,95％ CI:1.094 2.267,P=0.015),differentiation degree (HR=0.499,95％CI:0.340-0.732,P＜0.001),malignant serous effusion (HR=0.516,95％ CI:0.356-0.748,P＜ 0.001),chemotherapy (HR=1.669,95％ CI:1.185 2.351,P=0.003),and TCM (HR=1.793,95％ CI:1.237-2.600,P=0.002) were independent factors related to the prognosis of elderly patients with advanced GC.Conclusions The prognosis of elderly patients with advanced gastric cancer is poor,especially for patients with a low KPS score,a poor differentiation degree,or malignant serous effusion.Chemotherapy and TCM can improve the prognosis.

Objective To investigate the effect and mechanism of long noncoding RNA (lncRNA) PTEN pseudogene 1 (PTENP1) on the proliferation and migration of hepatocellular carcinoma (HCC) cells. Methods Lentiviral vectors expressing PTENP1 were constructed. HCC cells BEL-7404 were infected with LV003-GFP-PTENP1 and control vectors LV003-GFP. BEL-7404 cells stably expressing PTENP1 were constructed and the experimental and control groups were established. The proliferation and clone formation abilities of HCC cells in two groups were detected by CCK-8 assay and clonogenic assay. The migration ability of HCC cells was detected by wound healing assay. The expression of p44/42 mitogen-activated protein kinase (MAPK) and p38 MAPK proteins were detected by Western blot. Results The absorbance values A450 of the cells at 48 and 72 h in the experimental group were 1.4±0.3 and 2.3±1.1, signiifcantly lower compared with 3.2±1.7 and 3.4±1.1 in the control group (t=-5.78,-4.23;P<0.05). The number of cell clone formation in the experimental group was 55±12, signiifcantly less than 154±45 in the control group (t=-3.98, P<0.05). The percentage of cell migration in the experimental group was (21.7±2.6)%, signiifcantly lower than (57.7±4.9)%in the control group (t=-8.34, P<0.05). Western blot revealed that the expression of p44/42 MAPK and p38 MAPK proteins in the experimental group was significantly down-regulated compared with those in the control group. Conclusion lncRNA PTENP1 can inhibit the proliferation and migration of HCC cells probably through regulating MAPK signaling pathway.

Objective To investigate the effect and mechanism of liver cancer derived mesenchymal stem cell (LCMSC) on the invasion of liver cancer cells. Methods The expressions of interleukin (IL)-6, IL-8 and chemotactic factors CXCL1, CXCL5 and CXCL12 mRNA in the bone marrow derived mesenchymal stem cell (BMSC) and LCMSC were detected by reverse transcription-polymerase chain reaction (RT-PCR). The expression of protein CXCL12 in the supernate of LCMSC was detected by enzyme-linked immunosorbent assy (ELISA) and Western blot. Different cells were co-cultured and divided into the HepG2+BMSC, HepG2+LCMSC and HepG2+LCMSC+siRNA-CXCL12 groups. The effect of CXCL12 on the invasion of liver cancer HepG2 cells were detected by Transwell migration assay. The experiment data were compared using one way analysis of variance and LSD-t test or t test. Results The expression of CXCL12 mRNA in LCMSC was 60.3±2.4, significantly higher than 13.8±1.8 in BMSC (t=15.68, P<0.05). The expression of protein CXCL12 in the supernate of LCMSC was (31.5±1.7) ng/L, significantly higher than (14.3±1.5) ng/L in BMSC (t=7.60, P<0.05). And the expression of protein CXCL12 was up-regulated. Transwell migration assay indicated that the quantity of membrane-invasion cells in the HepG2+LCMSC group was 110±12, significantly higher than 65±9 in the HepG2+BMSC group and 76±7 in the HepG2+LCMSC+siRNA-CXCL12 group (LSD-t=5.25, 4.86; P<0.05). Conclusion CXCL12 is highly expressed in LCMSC. LCMSC may enhance the invasion of HepG2 cells through up-regulating the expression of CXCL12. The invasion of liver cancer cells can be effectively weakend by silencing the CXCL12 gene with siRNA.
