OBJECTIVE To monitor the sterilization effect of hydrogen peroxide gas plasma sterilizer with process challenge derice(PCD).METHODS Hydrogen peroxide gas plasma sterilizer was used to sterilize different material and structure items in simulation field sterilization trial.The test pieces have been cultured for 7 days at 37 ℃.Make the test records in detail.RESULTS The hemostatic forceps,surface of lines and biological indicators,as well as 300 mm stainless steels tube and 2000 mm Teflon tube were sterilized successful.But 600 mm and 300 mm stainless steels of low temperature did not past the challenge tests.The results of test surface and test lumen were inconsistent.CONCLUSIONS PCD is need to be introduced in monitoring sterilization effect of hydrogen peroxide gas plasma sterilizer.

Purpose:To explore the preventive effect of hepatic arterial infusion (DDS) against recurrence of hepato- cellular carcinoma (HCC) after radical resection.Methods:From Jan,1996 to May,1998,287 patients of HCC after radical resection were randomly divided into four groups:intra-hepatic arterial infusion(97),intra-portal vein(80),intra-hepatic artery and portal vein (60),control (50).All patients received chemotherapy for two years and observed for postoperative recurrence of HCC.Results:The postoperative recurrence rate of HCC with intra-hepatic arterial infusion was significantly lower than that of intra-portal vein (P0.05).The 1～、2～ and 3～year survival rate of intra-hepatic arterial infusion was significantly higher than any of the other groups.Conclusions:Intra-hepatic arterial infusion (DDS) through gastro-duodenal artery can effectively pro- long the postoperative survival and decrease the post-operative recurrence rate of HCC.The preventive method of DDS through gastro-duodenal artery was safer and effective.

group Nor(P0.05).Conclusions The changes of ambulatory pulse pressure can reflect the degree of EH.The obvious increase of PP and decrease of DBP maybe are the exclusive features of ABPM in EH patients with target organs damage.

Objective To study blood lipids levels of patients with ischemic cerebral vascular disease (ICVD).Methods The blood lipids levels were measured in 2886 subjects with ICVD enrolled from 1991 to 2004,in which 1430 subjects from 2000 to 2004 were classified into a sub-group;400 healthy persons receiving physical examination were enrolled as controls.Results The blood TC,TG and LDL-C levels were significantly higher in the sub-group than those in the control group.Both in males and females, the morbidity of abnormal blood lipid metabolism and blood lipids level gradually increased with the age and the lapse of decades.Total cholesterol level of male younger than fifty,averaging (4.43?0.51) mmol/L, increased to (4.96?0.85) mmol/L after fifty years old.The same thing happened to females,from (4.30?0.49) mmol/L to (5.01?0.90) mmol/L.TG and LDL-C increased in patients older than fifty compared with those younger than fifty.In the groups above 50 years old,the blood lipids levels of females were significantly higher than those of males.The morbidity of abnormal blood lipid metabolism of male increased from 24.5% in (1991 to 1994) to 38.1% (2001 to 2004) and of female from 22.3% (1991 to 1994) to 38.5% (2001 to 2004).Conclusions Abnormal blood lipid in Foshan is one of the most important reasons to ICVD.

A fusion expression vector pPIC3.5K-PDGFR? was constructed to express recombinant receptor tyrosine kinase PDGFR? and the right Pichia pastoris transformants were screened on his-deficient plates and YPD-G418 plates by turns after electroporation of strain GS115, a high yield strain named M3 was screened. The strain M3 was cultured in a 5 L fermentor and His-GFP-PDGFR? fusion protein was purified by Ni2+ chelating affinity chromatography. One distinct peak was obtained after elution with 250 mmol/L imidazole. Fusion protein was proved to be 90.08 kD by western blotting, and have tyrosine kinase activity by ELISA. Results showed that the receptor tyrosine kinase PDGFR? was successfully expressed in P. pastoris and could be used as a target for small molecule selective inhibitors screening.

Objective To investigate the reason of persisting positive rapid plasma reagin (RPR) in serofast syphilis patients, and to provide reference for clinical treatment and prognosis.Methods A total of 33 serofast patients and 23 healthy controls were enrolled in this study.The percentages and absolute counts of CD3+, CD4+, CD8+ T lymphocytes and natural killer (NK) cells were detected by flow cytometry.The comparison of two groups was analyzed by independent sample t test, and the correlation between change of lymphocyte subgroups and RPR titer in serofast syphilis patients was analyzed by bivariate linear correlation method.Results Compared with healthy controls, the percentages of CD3+, CD8+ T lymphocytes in serofast syphilis group were both increased significantly (75.75±5.76)% vs (68.37±5.80)%, (t=4.69, P<0.01);(27.34±7.02)% vs (24.33±1.95)%, (t=2.34, P=0.025), while both the percentage and absolute count of NK cells were significantly decreased (7.32±4.48)% vs (14.87±6.26)%, (t=5.269, P<0.01);(136.2±83.4)/μL vs (298.8±166.9)/μL, (t=4.311, P<0.01).RPR titer of the patients was negatively correlated with both percentage and absolute count of CD4+ T lymphocytes (r=-0.476 and-0.515, respectively, both P<0.01), and it was positively correlated of CD8+ lymphocytes (r=0.588 and 0.305, P<0.01 and P=0.804).Conclusion The imbalance of immune response of lymphocyte subsets observed in serofast syphilis may explain the RPR titers change.

Objective To investigate the effects of angiotensin Ⅱ (Ang Ⅱ) on the expression of vascular endothelial growth factor (VEGF) in human hepatic cancer cell line Hep G2.Methods Cultured Hep G2 cells were treated by AngⅡ with various concentrations and were collected at different time points.Then total RNA was extracted.The expression of VEGF mRNA in cultured Hep G2 was determined by relative quantitative reverse transcription polymerase chain reaction(RT-PCR),and the proliferation was detected by methyl thiazolyl tetrazolium (MTT).Results AngⅡ stimulated the proliferation of HepG2 cells,and enhanced the expression of VEGF mRNA (P
