Background and purpose: Blood biochemistry, ascites test and imaging diagnosis have low sensitivity for the diagnosis of abdominal neoplasma. And also exploratory laparotomy is not suitable for late stage patients. Real-time three-dimensional(3D) ultrasound is a new method in the diagnosis of celiac disease. We aimed to explore the application of this new tool in the diagnosis of abdominal cavity metastases of malignant tumor. Methods: Twenty-eight patients with malignant tumor preoperatively underwent both 2D and real-time 3D ultrasound examination The results were compared to pathological and clinical outcomes. Any one of those signs such as abdominal cavity mass, abdominal cavity lymphadenectasis, thickening of the peritoneum, nodules over the peritoneal and abdominal organs surface were considered as abdominal cavity metastases. Results: Twenty-five of them were pathologically confirmed to have abdominal cavity metastases. The diagnosis correlation rate of 2D and real-time 3D in the diagnosis of abdominal cavity metastases of malignant tumor were 42.86% and 92.86%, respectively. The sensitivity of these two methods was 37.5% and 95.83%, respectively. The speificity of two methods was 75.0%. The detection rates of the two methods were 16% and 96%, respectively. There were highly significant differences between two groups (P<0.001).Conclusion: Real-time 3D ultrasound had more value in the diagnosis of abdominal cavity metastases of malignant tumor in terms of sensitivity, specificity and positive detection.

Objective To study the influence of Yin-nourishing Qi-tonifying and blood-activating recipe(养阴益气活血方) on anticoagulation and fabrinolysis of cultured human umbilical vein endothelial cells(HUVEC).Methods Yin-nourishing Qi-tonifying blood-activating recipe was composed of three equal proportions of Radix Rehmanniae(生地黄),Radix Astragali(黄芪) and Rhizoma Chuanxiong(川芎);blood-activating recipe(活血方)contains Rhizoma Chuanxiong only.Serology pharmacology method was used to observe the effects of Yin-nourishing Qi-tonifying and blood-activating recipe on anticoagulation and fabrinolysis of cultured endotheliocytes of human umbilical vein.Results Compared with control group,both Yin-nourishing Qi-tonifying blood-activating and blood-activating recipes could obviously increase the content of 6-keto-prostacyclin 1?(6-keto-PGF1?) in HUVEC((412.5?42.7)ng/L and(231.7?30.1)ng/L vs.(137.6?13.5)ng/L),promote the activity of tissue plasminogen activator(t-PA)((0.920?0.072)kU/L and(0.679?0.062)kU/L vs.(0.516?0.052)kU/L),and inhibit the activity of tissue plasminogen activator inhibitor(PAI)((0.622?0.071)kAU/L and(0.851?0.085)kAU/L vs.(0.934?0.076)kAU/L),decrease the content of endothelin(ET)((35.7?4.9)ng/L and(46.8?5.1)ng/L vs.(58.6?6.2)ng/L),and increase the content of nitrogen monoxide(NO)((21.68?2.26)mmol/L and(15.15?1.73)mmol/L vs.(8.67?1.24)mmol/L) of cultured HUVEC(P

Objective To investigate the relationship between polymorphism in methylenetetra-hydrofolate reductase (MTHFR ) and acute cerebral infarction (CI), observe the variation regular of fasting plasma homocysteine (Hcy) level.Methods Using Homocysteine Microplate STE Assay to examine the fasting plasma homocysteine level of 28 CI patients during their initial stage (flaring up between 1 to 3 days) and later stage (flaring up 10 to 15 days) of acute period and 27 healthy controls. The presence of the MTHFR genetic type was determined by polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion.Results There was no significant difference among the three MTHFR genotypes in distributed frequency of the CI group, normal controls and the 677 allelic gene (P>0.05). The discrepancy of Hcy level in various kinds of genotypes: heterozygote mutation and homozygoto mutation were much higher than wild type (P<0.01). Homozygoto mutation was higher than heterozygote mutation, but there was no significant difference between them (P>0.05). The high homocysteine of group CI during the acute early stage were found out more frequent than normal control (P<0.05). There was no significant difference of fasting plasma Hcy level between the initial stage and later stage of CI group which were in acute period (P>0.05), both of the Results were higher than normal control (P<0.01). There was no significant difference among the Hcy level of various genetypes in CI group during the initial stage and later stage of acute period (P<0.05).Conclusion MTHFR gene C677T mutation is one of the cause of high homocystinemia, while it dose not lead to CI directly. High Hcy level is the independent risk factor of CI, but has no concern to the course of acute CI.

Objective To investigate the relationship between vascular cognitive impairment(VCI) and the angiotensinogen(AGT) gene ( G-6A and M235T) polymorphism. Methods Randomnized controled study was ap- plied in the study. AGT gene G-6A and M235T genotypes of 67 cases with VCI and 71 normal controls were deter- mined by polymerase chain reaction (PCR). Results For the location of M235T, the frequencies of T allele(0.73 I and TT genotype ( 0.52 ) were observed in VCI compared with control group ( 0.68,0.45, P > 0.05 ). The odds ratio associated with TT/MM genotype was 0.544 ( 95% CI 0.208～1. 424 ,P > 0.05 ). For the location of G-6A ,the fre- quencies of A allele(0.69) and AA genotype (0.48) were observed in VCI compared with control subjects (0.63, 0.39,P > 0.05). The odds ratio associated with AA/GG genotype was 0.602 ( 95% CI 0.252～1. 738, P > 0.05 ). There was no difference in allele distribution between 67 VCI patients and the controls. Conclusion There is no correlation between vascular cognitive impairment and AGT gene polymorphisms of M235T and G-6A. AGT gene pol- ymorphism is not included in the risk factors for development vascular cognitive impairment.

Objective To investigate the effect of cyclosporine A (CsA) on autophagylysosomal pathway in tubular epithelial cells.Methods Human renal tubular epithelial cell line (HK-2 cell) was treated with different concentrations (3,5 and 10 μmol/L) of CsA for 24 h.Then the viability and apoptosis of cells were measured by MTT assay or AnnexinV-PI staining followed by flow cytometry analysis,respectively.Autophagy-related protein LC3-Ⅱ and p62 were detected by immunofluorescence assay.Autophagic flux was analyzed in HK-2 cells transfected with a tandem mRFP-GFP fluorescent-tagged LC3 (ffLC3) plasmid by laser confocal microscope.The lysosomal degradation was evaluated by DQ-ovalbumin staining followed by flow cytometry analysis.Results The viability of HK-2 cells was significantly decreased with CsA stimulation when compared with control group (P ＜ 0.01),but the number of apoptotic cells was markedly increased by CsA treatment (P ＜ 0.05).Compared with the control group,different doses of CsA dramatically increased the expressions of LC3-Ⅱ (P ＜ 0.01) and p62 (P ＜ 0.05) in HK-2 cells.Moreover,HK-2 cells treated with CsA displayed a significant increase in autophagosomes but a marked decrease in autolysosomes.In HK-2 cells,exposured to CsA caused a decrease in lysosomal degradation by DQ-ovalbumin staining when compared with control group (P ＜ 0.01).Conclusion Blockade of autophagy via disrupting lysosome degradation may represent a novel mechanism of CsA-induced tubular epithelial cells injury.
