BACKGROUND:Deep venous thrombosis is one of the common and fatal complications of total joint arthroplasty.For our clinical practice,we require duplex ultrasound and venography to evaluate the presence of deep venous thrombosis,but the diagnostic tools have several disadvantages.OBJECTIVE:To explore the appropriate and non-invasive biomarkers in the early diagnosis of deep venous thrombosis.METHODS:With the key words of Thrombosis,DVT,Biomarker,Total Joint Arthroplasty,D-dimer,Factor VIII,Thrombin Generation,Fibrin Monomer,P-selectin,Inflammatory Cytokines,Microparticles,Leukocyte Count,Genetic factors,MicroRNAs,a computer-based search was performed for articles published in PubMed database from January 1995 to March 2015.After the initial screening,the reserved articles were further detailed,summarized and concluded.RESULTS AND CONCLUSION: Totaly 66 articles were colected.This brief review is used to analyze the mechanism of the biomarkers which are classified into three levels as folow: detection of blood coagulation,inflammation markers and molecular biology and genetics-based biomarkers.The review also showed a great need of economic and safer biomarkers for the clinic and provided the theoretical basis to diagnose and predict deep venous thrombosis in an early stage.

Objective To investigate the relationship among the plasma ET,CGRP and chronic atroph-ic gastritis (CAG). Methods One hundred and eighteen cases with GAG, 30 cases with chronic superficial gastritis( CSG) ;30 cases healthy individuals served as control group. The levels of plasma ET,CGRP were measured by radioimmunoassay. Results (1) ET levels were significantly higher in GAG than in CSG and control (P 0. 05) . (2) The levels of plasma ET is statistically different among mild, moderate and severe CAG(P 0.05). (3)The levels of plasma ET were negatively correlated with the levels of plasma CGRP (r = -0. 214,P =0.02). Conclusion It is suggested that ET and CGRP were possibly involved in the pathogenesis of CAG, and their variations in concentrations were related with the extent of CAG.

Objective:To investigate the expression of latent membrane protein-1(LMP-1),NET-1,and vascular endothelial growth factor(VEGF)in non-keratin nasopharyngeal carcinoma(NK-NPC)and its clinical significance.Methods :Sixty biopsy specimens from pathologically-confirmed NK-NPC patients,who were treated in the Affilitated Hospital of Nantong University from May 1999 to May 2003,were included in the present study.Using immunohistochemical techniques (Envison two-step),we examined the expression of LMP-1,NET-1 and VEGF protein in the specimens.The relationship between their expression and elnicopathological parameters and the prognosis was anayzed.Ten specimens of chronic nasopharyngitis served as control.Results:(1)The positive rates of LMP-1,NET-1 and VEGF in NK-NPC were significantly higher than those in the chronic nasopharyngitis(P0.05).(3)NET-1 and VEGF expression in NK-NPC specimens were positively correlated with lymph node metastasis and distant metastasis(P

Objective To observe the effect of supervised rehabilitation on functional recovery in hemiplegia patients after stroke.Methods 65 patients with acute stroke were divided into supervised rehabilitation group and no-supervised rehabilitation group. They were assessed with Ueda Test and Barthel Index before and after treatment. Results The scores of the Barthel Index in supervised rehabilitation group were significantly superior to those of the not supervised rehabilitation group (P <0.05), while the scores of Ueda Test between these two groups were not significantly different (P>0.05). Conclusion Supervised rehabilitation can improve the function recovery, especially in activities of daily living.

Objective To evaluate the clinical efficacy and safety for the CAG regimen combined with thalidomide in elderly patients with acute myelogenous leukemia (AML).Methods 51 untreated elderly cases with AML were randomly divided into treatment group (treated with CAG regimen combined with thalidomide,26 cases) and control group (treated with CAG regimen alone,25 cases),and the clinical efficacy and safety were observed.Results After 2 cycles of treatment,the complete remission (CR) rates of treatment group and control group were 61.5 ％ (16/26) and 48.0 ％ (12/25) respectively,the difference was not significant (P =0.404).With regard to prostecdtive efficacy,the difference was markedly significant,1-year CR rates of treatment group and control group were 53.8 ％(14/26) and 24.0 ％ (6/25) respectively (P =0.045),and 2-year CR rates were 42.3 ％ (11/26) and 12.0 ％ (3/25) respectively (P =0.027).During the follow-up of 2 years,overall 1-and 2-year overall survival rates were 73.1％ and 46.1％ in treatment group versus 52.0 ％ and 24.0 ％ in control group.During the follow-up of 2 years,the estimated mean overall survival time in treatment group was 22 months and it was 13 months in control group (P =0.018).The induction mortality rates and myelosuppression showed no difference between the two groups.Compared with control group,the side effect rate of nausea and vomiting was significantly decreased in treatment group (P =0.025).Conclusion The CAG regimen combined with thalidomide is effective with little side effects for elderly AML,and is worthy of further study and clinic application.

This study investigated the inhibitory effects of curcumin on proliferation of hematological malignant cells in vitro and the anti-tumor mechanism at histone acetylation/histone deacetylation levels. The effects of curcumin and histone deacetylase inhibitor trichostatin A (TSA) on the growth of Raji cells were tested by MTT assay. The expression of acetylated histone-3 (H(3)) in Raji, HL60 and K562 cells, and peripheral blood mononuclear cells (PBMCs) treated with curcumin or TSA was detected by immunohistochemistry and FACS. The results showed curcumin inhibited proliferation of Raji cells significantly in a time- and dose-dependent fashion, while exhibited low toxicity in PBMCs. Curcumin induced up-regulation of the expression of acetylated H(3) dose-dependently in all malignant cell lines tested. In conclusion, curcumin inhibited proliferation of Raji cells selectively, enhanced the level of acetylated (H(3)) in Raji, HL60, and K562 cells, which acted as a histone deacetylase inhibitor like TSA. Furthermore, up-regulation of H(3) acetylation may play an important role in regulating the proliferation of Raji cells.

CD44 is a transmembrane glycoprotein,which is a family of highly specific single chain mem-brane surface glycoproteins by a single gene.CD44 is mainly involved in the specific adhesion between cells and cells,cells and matrix.CD44v6 is a member of the CD44 family,and its correlation with metastasis and prognosis of non small cell lung cancer( NSCLC) has become a hot research topic in recent years.The current research pro-gress of CD44v6 and NSCLC are reviewed in this paper.

Objective To compared the effect of combined teaching method of lecture,case analysis and GasMan@software (LAG) and traditional teaching method (LBL) in inhalation anesthesia practice course.Method 78 anesthesiological undergraduates were randomly assigned to G group (n=39) or Control group (n=39).According to the requirements of clinical anesthesiology in the syllabus,G group used classroom lectures,case analysis and GasMan@software (LAG) teaching method,while Control group used lecture based learning (LBL) teaching method.The students took anonymous quiz and filled teaching effect evaluation form after practice course.Then the exam results were compared between groups to evaluate the teaching effect.SPSS 19.0 was applied to do statistical analysis and t test and x2 test were used.Results Compared to the Control group,G group got better results in objective questions like choosing,judgment,case analysis and average ranks (P=0.000),and there was no significant difference in the identification section (P=0.087),while G group also got better results in subjective questions like learning interests,study efficiency,memorize,logical thoughts,ability of analysis,solving problems and cooperation (P＜0.05).Conclusion Compared to traditional teaching method,the combined use of lecture,case analysis and GasMan@software make students immersive,develop their clinical thinking ability,and improve the teaching effect of inhalation anesthesia practice course significantly.
