Objective To investigate the hemostatic function of biological glue in renal trauma.Methods Establishment of rab-bit kidney scratch,partial nephrectomy and renal injury penetrating wound models were available with a biological glue and hemo-static powder processing,observed and recorded the amount of bleeding and bleeding time.Tissue sample were transected from the wound of kidneys in each group after a month,and the renal wound healing condition was observed by pathological examination.Re-sults The hemostatic function of biological glue was better than styptic powder,the amount of bleeding in biological glue group and hemostatic powder group of kidney scratched model were(1.39±0.09)mL,(1.77±0.44)mL,the difference was not statistically significant(P =0.115);the bleeding time were(5.02 ±0.23)s,(66.40± 7.35)s,the difference was statistically significant(P <0.01);the amount of bleeding in two models of partial nephrectomy and renal penetrating wound were(2.07±0.25)mL,(11.42± 1.33)mL;(2.01 ± 0.36)mL,(3.95 ± 0.39)mL and bleeding time were(6.16 ± 0.69)s,(139.38 ± 8.97)s;(7.68 ± 0.80)s, (144.26±9.27)s,the differences were statistically significant(P <0.01).Pathology results showed that the wounds healed well. Conclusion The hemostatic function of biological glue in renal trauma were remarkable and stable,and was worth to be further promoted.

Objective: To explore the association of the serum levels of cytokine IL-10 with the occurrence of cachexia from patients with low-third gastric cancer. Methods: Radioimmunoassay was used to examine the serum levels of IL-10 in 150 patients with low-third gastric cancer and 135 healthy controls. Results: The serum levels of IL-10 were significantly higher in patients with low-third gastric cancer than controls(Z=-11.862, P<0.01). The serum levels of IL-10 were significantly higher in patients with low-third gastric cancer of clinical stageⅢ/Ⅳ than those with clinical stageⅠ/Ⅱ(Z=-10.028, P<0.01). The serum levels of IL-10 were significantly higher in patients with cachexia than those without(Z=-10.369, P<0.01). Logistic regression analysis showed that IL-10 was associated with odds ratios of 1.599 (95%CI:1.299-1.870, P<0.01) for cachexia. Conclusion: The serum levels of IL-10 are possibly associated with the occurrence of cachexia from patients with low-third gastric cancer.

Objective By comparing the plasma levels of adiponectin respectively in colorectal carcinoma patients to healthy controls to discuss the relationship between adiponectin and colorectal carcinoma. Methods Plasma samples collected from 38 colorectal cancer cases, 38 healthy controls, respectively, were analyzed with a specific ELISA assay. Results The mean adiponectin levels in colorectal cancer pa-tients and healthy controls were 159.89 and 184.5 pg/mL,respectively. Obviously colorectal cancer patients had significantly lower plasma adiponectin concentrations compared with healthy controls(P=0.001). And a inverse correlation was found between plasma adiponectin levels and tumor size with significantly lower levels of adiponectin in tumors≥5 cm (P=0.04), while no similar relationship was found between adiponectin and p53, Dukes stages(P>0.05). Conclusions Lower plasma levels of adiponectin are associated with color-ectal carcinogenesis closely. And the lower plasma levels of diponectin were positively related to the degree of tumor size. It can presume that adiponectin play a vital role in the process of colorectal carcinogenesis.

Objective To analyze the detection rate of HBV serological makers in non-hepatic inpatients in the past six years. Methods Serum samples of 70 582 non-hepatic inpatients from three large hospitals were collected during 2003 to 2008. Serological markers of HBV ( HBsAg, anti-HBs, HBeAg, antiHBe and anti-HBc) were detected by the AxSYM MEIA system (Abbott Laboratories,Abbott Park,IL).Combining the test results of serological makers with other clinical data, several analysis models for this retrospective study were set up to evaluate the year-to-year changes in serological makers and the detection rates of each model. Results The order from high to low of detection rate of the 5 HBV serological markers was anti-HBc (55. 17% ), anti-HBs (49. 57% ), anti-HBe (28.42%), HBsAg ( 8. 92% ) and HBeAg (2. 12% ), and all of them had a downward trend in the past six years. The positive rate of HBsAg went down from 9. 30% (2003) to 8.70% (2008). The positive rate of HBsAg among people who were born after 1992 (2. 28% ) were significantly lower than that of the overall population (8. 92% ) and fell from 3.57%(2003) to 1.85% (2008). Each detection rate of all serological makers had male sexual side effect [HBsAg ( 12. 38%/7. 25% ), HBeAg ( 2. 72%/1.58% ), anti-HBc ( 56. 57%/53.43% ), anti-HBe (41.50%/28. 35% ) and anti-HBs (65.48%/50. 00% ), male/female]. The differences were statistically significant (Chi-square values of HBsAg, HBeAg, anti-HBc, anti-HBe and anti-HBs were 509.74,105.78, 69.66, 1 321.61 and 1 726.91, respectively; all P ＜ 0. 01).Twenty-six models of HBV serological makers from 70 582 inpatients were summed up, and 8 models had positive rates geater than or equal to 1%. The "All Negative" model ranked No. 1 and had no significant change from year to year. During the past six years, models representing "A11 Negative" and "anti-HBs Positive alone" were mainly in individuals younger than or equal to 20-year-old, while the models representing "anti-HBc and/or anti-HBe,anti-HBs Positive" were mostly in people older than 20-year-old. The distribution curve of models representing "HBsAg, HbeAg and anti-HBc Positive" and "HBsAg, anti-HBc, anti-HBe Positive"etc. showed a bell-shape, covering the population from 20-year-old to 70-year-old. Conclusions The slowlydescending tendency of the detection rates of HBV serological makers was observed during the past six years.The detection rates of HBV in the younger generation decreased significantly. However, the HBV infection rates of overall population is still high, so it is a high time that we made continuous improvement for the serum HBV screening technique in order to reduce the HBV infection ratess.
