OBJECTIVESTo investigate incidence of perioperative cardiovascular events, to analyze related risk factors for the patients undergoing intraperitoneal surgery.
METHODSThe data of 1079 patients who underwent intraperitoneal surgery (exclude laparoscope surgery) from July 2007 to June 2008 was reviewed and analyzed.
RESULTSFor the patients undergoing intraperitoneal surgery, the incidence of major cardiovascular events was 3.99% (43/1079), all-cause mortality was 1.58% (17/1079). The independent risk factors of major cardiovascular events were age ≥ 60 years, history of coronary heart disease, cardiac insufficiency, arrhythmia, chronic obstructive pulmonary disease, estimated glomerular filtration rate (eGFR) < 60 ml/(min·1.73 m(2)), emergency surgery and duration of surgery > 2.82 h (OR = 2.68 to 5.19, P = 0.001 to 0.031).
CONCLUSIONSThe cardiac risk of intraperitoneal surgery is 3.99%. The risk of cardiac complications should be evaluated in elderly patients and those with ischaemic heart disease, chronic obstructive pulmonary disease, and renal disease, more specifically, when emergent or long duration major surgeries are needed.

BACKGROUND: The aims of this study were to understand the molecular epidemiology of integron-associated gene cassettes in Acinetobacter baumannii across four hospitals in northern Taiwan and to clarify the relationship between the presence of integrons and antibiotic-resistant phenotypes. METHODS: Sixty-five A. baumannii isolates, collected from the patients of four regional hospitals in northern Taiwan in 2009, were tested for the presence of integrons and their associated gene cassettes. The susceptibility difference between integron-positive and integron-negative A. baumannii strains was analyzed. Antibiotic-resistant phenotypes among A. baumannii with different types of gene cassette array combinations were also compared. RESULTS: Around 72% of the A. baumannii isolates carried class 1 integrase genes. Despite this, only three gene cassette arrays were found in the integrons. Integron-positive strains were significantly more resistant to all the tested antibiotics than the integrase-negative strains. All the four types of A. baumannii with different gene cassette array combinations were multidrug-resistant in nature. Gene cassette array aacA4-catB8-aadA1 existed in all the integron-positive A. baumannii isolates. Repetitive-sequence-based PCR (rep-PCR) results revealed the prevalence of one major cluster of imipenem-resistant A. baumannii strains (84%) in the four regional hospitals. CONCLUSIONS: The presence of integrons with associated antimicrobial resistance gene cassettes can be used as a representative marker of multidrug resistance in A. baumannii. Some prevalent gene cassette arrays may exist among epidemiologically unrelated A. baumannii strains.

OBJECTIVETo study the expression level and intracellular localization of APOBEC3G in peripheral blood mononuclear cells (PBMCs) and liver tissues of chronic HBV patients.
METHODSThe expression level and intracellular localization of APOBEC3G in PBMCs and liver tissues were detected using the western blot and confocal laser scanning microscope (CLSM).
RESULTSWestern-blot showed that the expression level of APOBEC3G in PBMCs of healthy controls was very low. The relative expression levels of APOBEC3G in PBMC of patients with chronic hepatitis B, chronic severe hepatitis, liver cirrhosis, or liver cancer were 4.12+/-0.21, 4.07+/-0.28, 4.16+/-0.36 or 4.21+/-0.39 respectively, which were higher than that in the healthy controls. However, there was no significant difference in APOBEC3G expression among different chronic HBV patients (q = 0.931, 0.744, 1.675, 1.675, 2.606 or 0.931, respectively, all P values more than 0.05). In addition, there was no significant difference on APOBEC3G in liver tissues between chronic hepatitis B patients and hepatocellular carcinoma patients (4.40+/-0.34 vs 4.34+/-0.43, q = 0.588, P more than 0.05). CLSM indicated that the localization of APOBEC3G protein was in cytoplasm of PBMCs and hepatocytes.
CONCLUSIONAPOBEC3G is upregulated in the PBMCs of chronic hepatitis B patients.

OBJECTIVEWe investigated the in vivo effects of recombinant adenovirus-associated virus type-2 (AAV-2) mediated interleukin-10 (IL-10) gene transfer on the expression of matrix metalloproteinase (MMP)-2, 9, tissue inhibitor of metalloproteinase (TIMP)-1, collagen type I and type III in a rat acute myocardial infarction model.
METHODMale Sprague-Dawley (SD) rats were randomly divided into three groups (each n = 6): sham operation group, MI/AAV2 group, and MI/AAV2-IL-10 group (10(10) vg/ml x 0.1 ml injection at peri-infarct regions immediately post MI). Five days later, the expressions of MMP-2 and MMP-9 were measured by RT-PCR, Western blot and zymography. The expression of TIMP-1 was measured by RT-PCR and Western blot. Collagen type I and type III were assessed by RT-PCR and immunohistochemical stain.
RESULTSThe myocardial expressions of MMP-2, MMP-9 and collagen contents in MI/AAV2 group were significantly increased than those in sham operation group. Myocardial expressions of MMP-2, MMP-9 were significantly decreased and the expression of TIMP-1 significantly increased in the MI/AAV2-IL-10 group than those in MI/AAV2 group. Moreover, the expressions of collagen type I, collagen type III and the ratio of I/III collagen in border zones of infarcted myocardium were decreased by 47.6% (P < 0.01), 23.6% (P < 0.05), and 17.9% (P < 0.05) respectively, while the expression of TIMP-1 increased by 73.1%(P < 0.05) in MI/AAV2-IL-10 group compared to MI/AAV2 group.
CONCLUSIONIn vivo myocardial IL-10 transfer reduced myocardial MMP and collagen expression and increasing the TIMP expression.

OBJECTIVETo observe effect and mechanism of n-Butanol lysate of alcohol extracts from Actinidia rufa root (monomer of R6,R8).
METHODTunel, Wright's stain with Giemsa's stain dyeing, and Hoechst 33258-PI double dyeing assay were used to detect the apoptosis of SGC7901 tumor cells treated with R6, R8. The SGC7901 tumor cells were randomly divided into control group and two treatment groups administered 0.05 g x L(-1) R6, R8, respectively, for 72 h). FCM assay was used to detect the apoptosis. Agarose electrophoresis assay was used to detect DNA strand break of tumor cells and reveal anti-tumor action mechanism.
RESULTThe apoptosis percentage of the tumor cell in 24 h, 48 h, 72 h was (17.08 +/- 2.78)% , (29.68 +/- 2.96)%, (52.46 +/- 3.81)%; (14.75 +/- 2.14)%, (27.35 +/- 3.79)%, (45.64 +/- 5.24)%, respectively, for the treatment group, significantly higher than that in the control group (1.94 +/- 1.55)%, (2.78 +/- 1.84)%, (11.8 +/- 2.79)% (P < 0.01) by tunnel assay. Wright's stain with Giemsa's stain dyeing assay, Hoechst 33258-PI and FCM double dyeing assay showed same action. R6 and R8 had the effect of inducing the DNA histogram of tumor cells (P < 0.01).
CONCLUSIONThe anti-tumor mechanisms may be associated with inducing the injury of DNA and stimulating apoptosis.
