Objective To investigate the correlation between the coagulation function and fibrinolytic activity with deep venous thrombosis (DVT) after traumatic fracture operation.Methods One hundred and thirty-four cases of traumatic fracture from April 2010 to May 2014 were divided into the DVT group(24 cases) and non-DVT group,and at the same time 110 healthy people were selected as the control group.The venous blood at different time points was collected for observing the levels change of prothrombin time (PT),activated partial thromboplastin time (APTT),fibrinogen (FIB),platelet aggregation rate (PAgT),dipolymer (D-D),thrombin antithrombin complex (TAT),plasminogen activity (PIg) by using appropriate methods.Results There was no difference in APTT and PT groups among the groups(P>0.05).Preoperative FIB,PAgT,D-D and TAT levels was the DVT group >non-DVT group > control group,while the level of PIg was the DVT group0.05).Conclusion The increase of D-D and TAT is closely related with DVT in traumatic fracture and,which is an independent risk factor.

Objective: To screen the extraction process of volatile oil in Supplemented Xanthium Powder.Methods: The main compositions of volatile oil contained by every herb in prescription were followed up by GC MS. Results: The extraction process of volatile oil in Supplemented Xanthium Powder was established, that is, Flos Magnoliae and Cortex Moutan Radicis were powdered, their volatile oils were extracted with Herba Menthae together by the steam distillation; then 13 fold first fraction of distillata and 3 fold redistillation liquid were collected respectively; the volatile oil of Rhizoma Liqustici Chuanxiong was extracted with alcohol. Inasmuch as Fructus Xanthii and Radix Angelicae Dahuricae contained less volatile oil, at the same time, to avoide that Fructus Xanthii produced toxicity by water extraction and coumarinic lactones of Radix Angelicae Dahuricae was destroyed their oils were considered unfit for extraction. Conclusion: GC MS is a useful way for follow up optimization of the extraction process of volatile oil in compound prescription of Chinese medicinal and worthy of popularization.

Objective To explore the adiponectin expression in the chronic hepatitis B (CHB) patients and compare the level of edipanectin before and after antiviral therapy, and investigate the relationship between ediponectin and CHB. Methods Serum adiponectin was detected by enzyme linked immunosorbent assay (ELISA), and the expression of adipanectin in liver tissue was detected by palymerase chain reaction (PCR) and immunohistochemistry. The liver functions and HBV DNA were also tested. Liver biopsy tissue was assessed by fibrosis stage. Results Serum adipanectin in CHB liver cirrhosis [(20.65 ± 1.29) mg/L]was higher than that in other stage fibrosis, the values were (8.57 ± 0.28 ), (12.22 ± 0.64), (15.22 ± 0.77 ) mg/L (P< 0.01 ). Serum adiponectin was positively associated with fibrosis stage(r = 0.976,P< 0.01 ). There was no significant difference between HBV DNA and ALT (P> 0.05 ). Serum adipanectiu was independently associated with liver cirrhosis (r = 1.07, P = 0.02, 95% CI = 1.00-l.14).At the end of antiviral therapy,the expressions of adiponectin declined in patients with improved fibrosis and sustained viral response. Conclusion Serum adiponectin may play a role in CHB fibrosis, and reduced adipanectin level is associated with improved fibrosis after antivital therapy.

Objective To analyze the genotype of varicella-zoster virus (VZV) strains isolated from patients with chickenpox or zoster and to differentiate them from Oka vaccine strain by molecular analysis. Methods In the present study, single nucleotide polymorphisms(SNP) based VZV genotypes were analyzed in 19 VZV isolates using the polymerase chain reaction and restriction fragment length polymorphisms analysis of DNA fragments of the open reading frames 38, 54, 62, and the 1t5 repeat region. Results The genotypes of 19 VZV isolates including two different groups with 52.7% of Pst Ⅰ+ Bgl Ⅰ+ R5A and 47.3% of Pst Ⅰ+ Bgl Ⅰ+ R5B, which is very different from those found in North America, Europe and Japan. All the Chinese isolates are wild-type strains with ORF62 Sma Ⅰ-. No Oka vaccine strains were revealed among the isolates. Conclusion Chinese VZV strains reported in this study showed different molecular characteristics from those circulating in Europe, North America and Japan. The SNPs in ORF62 and ORF38 may be used to distinguish VZV wild-type strains and vaccine strain in clinical isolates in China.

AIM:To investigate the change of short-chain acyl-CoA dehydrogenase (SCAD) expression during cardiomyocyte apoptosis and to explore the relationship between SCAD and cardiomyocyte apoptosis .METHODS: The neonatal rat cardiomyocytes treated by tert-butyl hydroperoxide (tBHP) were used as the model of cardiomyocyte apoptosis . The cell viability , the expression of SCAD at mRNA and protein levels , the activity of SCAD and the content of free fatty acids were determined .RESULTS:The mRNA and protein expression of SCAD decreased in the cardiomyocyte apoptosis model.Compared with negative control group , SCAD expression and activity were both significantly decreased in siRNA-1186 group, but the content of free fatty acids were obviously increased in the cardiomyocytes .Meanwhile, SCAD siRNA treatment triggered the same apoptosis as cardiomyocytes treated with tBHP .CONCLUSION: Down-regulation of SCAD may play an important role in primary cardiomyocyte apoptosis .Increase in the expression of SCAD may become an impor-tant part in intervening cardiomyocyte apoptosis .

Objective To evaluate the value of renal parenchymal volume and thickness by non-contrast spiral CT in evaluating the differential glomerular filtration rate (GFR) for chronic obstructed kidneys, and to compare the correlations between the two morphologic indices of renal parenchyma and the GFR for chronic obstructed kidneys. Methods Seventy-one patients who had a diagnosis of unilateral chronic upper urinary tract obstruction were included in this analysis. (1) The renal parenchymal volume was mea-sured by non-contrast spiral CT. Both kidneys were scanned by non-contrast spiral CT. The renal parenchymal area of each section was marked manually. Renal parenchymal volume was calculated as the sum of renal parenchymal area multiplied by the width of each section. The volume percentage of obstructed kidney (%CTvol) was also calculated. (2) Renal parenchymal thickness was measured on the first and last non-contrast CT image levels from the anterior, posterior and lateral locations of the kidney that clearly contained the collecting system. The mean of these measurements was defined as the renal parenchymal thickness. The differential renal parenchymal thickness of the obstructed kidney (%CTt) was defined as the percentage of the obstructed renal parenchymal thickness to the total renal parenchymal thickness for both kidneys. GFR was determined with 99Tcm-DTPA dynamic imaging system by Gates method. The differential GFR for obstructed kidney (%GFR) was the GFR percentage of obstructed kidney to the total GFR for both kidneys. The Pearson relation test was carried out between the %CTvol, %CTt and the %GFR respectively. Results %CTvol and %CTt correlated well with %GFR in chronic obstructed kidneys among the 71 test group patients. Pearson correlation coefficient r was 0.80 (t=11.20, P＜0.05) and 0.66 (t=7.24, P＜0.05), respectively. The linear correlation equation respectively was %GFR=0.05+0.80×%CTvol (F=125.48, P＜0.05) and %GFR=0.12+0.66×%CTt (F=52.36, P＜0.05). Conclusions Renal parenchymal volume and thickness by non-contrast spiral CT might be used as clinical practical parameters to evaluate the differential GFR for chronic obstructed kidneys. Renal parenchymal volume is more accurate than renal parenchymal thickness.
