Objective:To compare the clinical efficacy of percutaneous radiofrequency ablation (RFA) under ultrasound guidance and high power microwave ablation (MWA) in the treatment of intermediated or advanced-staged primary liver cancer.Methods: 60 patients with primary liver cancer who were in accordance with the inclusion criteria were divided into radiofrequency ablation group (RFA group, 30 cases) and microwave ablation group (MWA group, 30 cases). A series indicators, such as postoperative complete remission rate of lesion, 1 year survival rate, 1 year progression-free survival rate, postoperative adverse reaction and postoperative complication, for these patients of two groups were compared and analyzed.Results:The total complete remission rate of the RAF group and the MWA group were 66.7% and 76.7%, respectively, and the difference between them was significant (x2=3.776, P<0.05). When the lesion was larger than 5 cm, the complete remission rate of RFA group and MWA group were 41.7% and 63.6%, respectively, and the difference between them was significant (x2=4.231,P<0.05). When the lesion was between in 3-5 cm, the complete remission rate of RFA group and MWA group were 75.0% and 81.2%, respectively, while the difference between them was no significant (x2=0.976,P>0.05). For postoperative complication, there were 3 cases in RAF group while there were 5 cases in MWA group, and the difference between them was significant (x2=3.373, P<0.05). There was no death case that was related with treatment in the two postoperative groups. The 1 year survival rate and 1 year progression-free survival rate of RAF group were 90.0% and 53.3%, respectively, and that of MWA group were 86.7% and 60.0%, and the difference between them was no significant (x2=0.877,P>0.05).Conclusion: For intermediated or advanced-staged primary liver cancer with the larger or multiple lesions, complete remission rate of high-power MWA group is better than that of RAF. But there was no significant difference for 1 year total survival rate and 1 year progression-free survival rate between the two groups, respectively. And the postoperative adverse reaction of high-power MWA group was higher than that of RAF group.

Objective To investigate the effect of isosorbide mononitrate on the levels of NO,iNOS,IL-1 and IL-6 in lung tissue of spontaneously hypertensive rats (SHR).Methods Fourteen-week-old Wistar and SHR male rats were randomly divided into the W0,W1,S0 and S1 group,with 10 rats ineach group.Rats in the W0 and S0 group were fed with the normal saline and the ordinary food,rats in the W1 and S1 group were fed with isosorbide mononitrate and the ordinary food.Twelve weeks later,levels of NO,iNOS,IL-1 and IL6 in rat lung tissue were detected.Results Compared with the W0 group,levels of NO,iNOS,IL-1 and IL6 were significantly increased in the W1 groups (P ＜ 0.05,respectively).Compared with the SO group,levels of NO,iNOS,IL-1 and IL6 were significantly increased in the S1 group (P ＜ 0.05,respectively).In the W1 and S1 group,levels of iNOS and NO were positively correlated with IL-1 and IL-6.Conclusion 1.Isosorbide mononitrate may lead to increases of NO,iNOS,IL-1 and IL6 in lung tissue of Wistar rats,which indicates the presence of chronic inflammation.2.Longterm feeding of isosorbide mononitrate may lead to increases of inflammatory factors in SHR rats,contributing to the inflammatory state in rats.

Objective To evaluate the long-term effect and safety of triple antiplatelet therapy(cilostazol,aspirin and clopidogrel)for the patients with diabetes and acute coronary syndromes(ACS)undergoing percutaneous coronary intervention(PCI).Methods Between December 2004 and February 2006,a randomized,single center trial was conducted in General Hospital of Shenyang Command for comparison of dual and triple antiplatelet therapy after PCI for the patients with ACS.Of 263 diabetic patients enrolled in present study,122 were randomly assigned to standard dual antiplatelet treatment with aspirin and clopidogrel,141 were assigned to triple antiplatelet therapy with aspirin,clopidogrel and cilostazol.Primary endpoint was a composite of cardiac death,non-fatal myocardial infarction(MI),stroke or target vessel revascularization(TVR)at 1 year.Results Baseline clinical and angiographic characteristics were comparable between the two groups.No definite stent thrombosis or MI occurred in either group during the period of follow-up,and no significant difference existed yet in the rates of 1-year cardiac death(4.1% vs 1.5%,P=0.255),stroke(3.3% vs 0.7%,P=0.186)and TVR(12.3% vs 7.8%,P=0.223)between the patients received dual or triple antiplatelet therapy.The rate of primary events was 9.9%(14/141)in triple group,which was significantly lower than that in dual group [18.9%(23/122),P=0.038].Patients receiving hypoglycemic medicine got more benefits from triple antiplatelet treatment.There was no significant difference between the two antiplatelet regimens regarding the risk of hemorrhagic events and premature discontinuation of aspirin or clopidogrel.Conclusion The regimen of cilostazol plus aspirin and clopidogrel for diabetic patients undergoing PCI is effective and safe in reducing long-term adverse cardiac and cerebral-vascular events,especially for the patients with high dangerous DM complicated with ACS.

Objective To evaluate the applied of selected intraoperative cholangiography(SIOCG) during cholecystectomy.Methods The SIOCG data of 39 patients who had indications for exploration of common bile duct were analysed retrospectively.Results Among 39 cases with SIOCG,abnormal findings were detected in 19 cases(48.72%),in which choledocholith in 16 cases;stenosis of common bile duct at the third part in 3 cases.Positive findings in exploration of common bile duct were 14 cases(73.68%),in which,choledocholith were 12 cases inflammatory stenosis 1 case and tumor of common bile duct at the third part 1 case.Negative patients in exploration of common bile duct were 5 cases(26.32%).Normal imaging in 20 patients who did not underwent exploration of common bile duct had no disorders in follow-up.Conclusion SIOCG is safe,convenient,and useful in preventing the remnant stones and biliary tract damage and improving the quality of cholecystectomy.

To investigate changes in Toll-like receptor 2 (TLR2) gene expression in postburn Staphylococcus aureus infection, and its potential signaling mechanism, 68 male Wistar rats were randomly divided into four groups as follows: normal control group (n=6), scald control group (n=6), postburn sepsis group (n=36),AG126 treatment group (n=10) and pyrrolidine dithiocarbamate (PDTC) treatment group (n=10). Tissue samples from the liver, kidney and lung were collected from every group to determine TLR2 and tumor necrosis factor-? (TNF-?) mRNA expression. The results showed that TLR2 mRNA expressions in the liver, kidney and lung from postburn septic animals were up-regulated rapidly, peaking at 0.5-2 hours (P

Objective To observe the change in interleukin-18 (IL-18) mRNA expression in cecal ligation and puncture (CLP) induced sepsis, and to investigate its potential role in the pathogenesis of endotoxemia. Methods Fifty-four Wistar rats were randomly divided into normal group (n=6), CLP group (n=36) and recombinant bactericidal/permeability increasing protein (rBPI 21) treatment group (n=12). Tissue samples from the liver, lungs and kidneys were collected to determine IL-18 mRNA expression. Meanwhile, tissue endotoxin level and the indexes of organ function were also measured. Results After CLP, endotoxin levels in the liver,lungs and kidneys were significantly increased, peaking at 2-12h (P

To determine the role of biopterin in acute lung injury in scald rats with infection, and to observe the therapeutic effect of GTP-cyclohydrolase I(GTP-CHI) inhibitor on postburn sepsis, 56 male Wistar rats were randomly divided into four groups: normal controls (n=10), scald control group(n=10), postburn sepsis group(n=20) and 2,4-diamino-6-hydroxy-pyrimidine (DAHP) treatment group (n=16). Tissue samples from lungs were collected to determine GTP-CHI and inducible nitric oxide synthase (iNOS) mRNA expression, meanwhile biopterin, nitric oxide (NO), tumor necrosis factor-?(TNF-?) and interferon-? (IFN-?) levels in lungs were also measured. The results showed that after scald injury followed by Staphylococcus aureus challenge, GTP-CHI gene expression and biopterin levels significantly elevated in lungs, so did the values of iNOS mRNA expression and NO induction (P

Objective To observe the early rehabilitation effect of mild hypothermia on patients with herpes simplex viral encephalitis (HSE). Methods A total of 58 patients with HSE were randomized into two groups, a mild hypothermia therapy group (30 cases) and a normothermia control group (28 cases). Their rectal temperatures were controlled to (34±1)℃ and (37.0±0.5)℃ respectively. Serum levels of neuron specific enolase (NSE) were determined through radio-immunoassay (RIA). Soluble intercellular adhesion molecule-1 (sICAM-1) was measured with ELISA before and 1, 3, 5, and 7 d after treatment. The outcome was evaluated using the Glasgow Outcome Scale (GOS) 30 days after treatment. Results Compared with the normothermia control group, the mild hypothermia group's serum levels of NSE and sICAM-1 decreased quickly and significantly during the early stage of treatment and remained better 30 d later. Conclusion Mild hypothermia therapy can dramatically reduce inflamma-tion and facilitate the rehabilitation of damaged neurons, provide protective effects and improve the outcome for pa-tients with SHE.
