Objective To evaluate the clinical effect of restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for refractory ulcerative colitis (UC).Methods In this study 60 refractory UC patients received IPAA operation during the period of 1990 to 2010.Data were collected regarding early and late postoperation complications,anal continence function,and characteristics of feces.The patients' quality of life was objectively accessed using the Clevend Global Quality of Life (CGQL)index.0ne-way analysis of variance was used.Results Mean follow-up period was 2 years.Early postoperative complication rate developed in 15％ (9/60),including abdominal or pelvic infection,anastomotic leak,pouch bleeding,pouch-vaginal fistula,and intestinal obstruction.Late postoperative complication rate was 12％ (7/60),including pouchitis,intestinal obstruction,and male sexual dysfunction.Stool frequency per 24 hours and that at night was 3.5 ± 1.3 and 1.4 ±0.6.93％ (56/60)patients differentiated gas and feces well and 3％ (2/60) needed daily pads.According to Kirwan Grading Scale,anal function outcomes were Grade Ⅰ:54 (90％),Grade Ⅱ:4 (7％),and Grade Ⅲ:2 (3％).According to Bristol Stool Form Scale,characteristics of feces were Grade Ⅳ:31 (52％),Grade Ⅴ:25(42％),and Grade Ⅵ:4 (6％).Postoperative CGQL result showed a much better quality of life than preoperative CGQL (F =12.368,P ＜ 0.05).Conclusions Refractory UC is surgically indicated and IPAA is the operation of choice with safety,satisfactory long-term outcome and improved quality of life.

Background: Inducible T-cell co-stimulator (ICOS)is a member of the B7-CD28 family, which plays roles in various biological processes including cell proliferation, differentiation and immune responses, and is closely related to immune escape in many malignant tumors. Aims: To investigate the expression and significance of ICOS in colorectal cancer (CRC). Methods: Thirty-two pairs of fresh CRC tissues and adjacent non-cancerous tissues, as well as 211 cases of paraffin-embedded CRC tissues were collected for detection of ICOS mRNA and protein expressions by real-time PCR and immunohistochemistry, respectively. Correlations between ICOS expression and clinicopathological characteristics and prognosis were analyzed. Results: In comparison with adjacent non-cancerous tissues, expression of ICOS was significantly lower in CRC tissues (P<0.05), and correlated negatively with the tumor size, serum CEA, lymph node metastasis, distal metastasis and TNM staging (P all <0.05). No significant difference in ICOS expression was found in tumors from different location (P>0.05). Kaplan-Meier survival analysis suggested a poorer prognosis in CRC patients with lower ICOS expression (P<0.05). Multivariate Cox regression analysis confirmed that ICOS expression could be an independent prognostic factor for CRC (HR=0.821, 95% CI: 0.588-0.912, P=0.034). Conclusions: ICOS is lowly expressed in CRC tissues and is associated with tumor progression and poor prognosis. It might be a promising molecular marker for predicting prognosis of CRC.

This study determined the profile of renal insufficiency in patients without chronic kidney disease(CKD)undergoing coronary revascularization and elucidated the effect of renal insufficiency of different degrees on clinical outcomes after revascularization and examined whether the reasonable choice of the mode of revasoularization could favourably influence prognosis.Methods Patients undergoing coronary revascularization were grouped by estimated creatinine clearance(CrCl)(Group Ⅰ,CrCl≥90 ml/min;Group Ⅱ,60 CrCl<90 ml/min;Group Ⅲ,30≤CrCl<60 ml/min;Group Ⅳ,CrCl<30 ml/min).We evaluated the relationship between the CrCl and the clinical outcomes of all of the patients.Results The mean Scr level of 2896 patients was(80.0±35.4)μmol/L There were 1035 patients(35.7%)in Group Ⅰ,1337 patients(46.2%)in Group Ⅱ,524 patients(18.1%)in Group Ⅲ and no patient in Group Ⅳ.During hospitalization,significant difference was found among Group Ⅰ-Ⅲ on mortality (1.0%.2.5% and 2.9%,P=0.009)and major adverse cardiar cerebra tvents(MACCE)(1.4%,3.5% and 4.6%.P=0.001).Compared with the normal renal function group,there were significantly higher rate of mortality(2.5% vs.1.0%,P=0.007).new-onset myocardial infarction(1.0% vs.0.2%,P=0.018)and MACCE(3.5% vs.1.4%,P=0.002)in miid renal insufficiency(Group Ⅱ).During follow-up,there were significant difference among Group Ⅰ-Ⅲ on mortality(2.0%,3.0% and 5.7%,P=0.002),stroke(1.0%,1.8% and 3.1%,P=0.023)and MACCE(9.9%,10.3% and 16.6%,P=0.001).The independent risk factors for all-cause death in patients after revascularization were the mode of revascularization(OR 8.332,95% CI 2.386-22.869,P=0.001).age(OR 1.184,95% CI 1.020-1.246,P=0.001).and the level of CrCl(OR 0.503,95% CI 0.186-0.988,P=0.045).In patients with normal renal function and mild renal insufficiency.the all-cause mortality after PCI was significantly lower that than after CABG(both P<0.01).Conclusions Renal insufficiency is common in patients without CKD undergoing coronary revascularization,even mild renal insufficiency is correlated with adverse clinical outcomes after revascularization.In patients with normal renal function or mild renal insufficiency,the mode of revascularization might lead to a prognostic difference.

Objective To prospectively evaluate the feasibility and reliablity of low kilovoltage contrast-enhanced multi-slice CT(MSCT)to detect the myocardial viability in chronic myocardial infarcetion.with comparison to magnetic resonance(MR)myocardial perfusion and viability imaging.Methods Thirty-two patients with clinical diagnosed chronic myocardial infarction underwent the first pass and delayenhanced myocardial imaging with 64-slice MSCT and MR Left ventricle was divided into 16 segments.MSCT and MR images of all the patients were blindly analyzed.The size and extent of hypoenhanced regions in first pass phase and hyperenhanced regions in delayed phase were define.The Kappa test was used to assess the ability of identifying the viable myocardium between the two methods.Results In 32 patients with chronic myocardial infarction,MSCT showed hypoenhanced regions in 41 segments and normal in 471 segments during the first phase,while MRI revealed hypoenhanced regions in 47 segments and normal regions in 465 segments.The Kappa value was 0.650 and the concordance rate of the two techniques was 94.5%(484/512).MSCT showed 135 hyperenhanced regions which were non-transmural in 50 segments and transmural in 85 segments.And the other 377 normal segments showed no enhancement in the delayed phase.MRI revealed 120 hyperenhanced regions which were non-transmural in 56 segments and transmural in 64 segments.And the other 392 normal segments showed no enhancement in the delayed phase.The Kappa value of the two techniques was 0.609 and the concordance rate of the two techniques was 80.7% (413/512).Conclusion The study showed that low kilovolrage CE MSCT has a good concordance with MRI and has high feasibility and reliability in evaluating the myocardial viability in chronic myocardial infarction.The radiation dose is still the important aspect of MSCT application.

Objective To assess whether anemia is an independent predictor of poor long-term outcome after percutaneous coronary intervention(PCI).Methods The second drug-eluting stent impact on revascularization registry(DESIRE-2)is a single-center registry of 6005 patients undergoing coronary revascularization from July 2003 to September.2005.We examined the clinical data and outcome of 3809 PCI patients based on hemoglobin(Hb)value before the interventional procedure.Patients were classified as anemia using the World Health Organization deftnition(＜120 g/L in women and＜130g/L in men). 744 of the 3809 patients were anemic.We compared the clinical features and prognosis of the patients with or without anemia.Results Anemic patients were older and had a higher percentage of comorbidities as compared with the nonanemic ones.When compared with nonanemic patients,anemic patients had higher mortality(4.7%VS 1.5%,P＜0.001)and higher major adverse event end points,including nonfatal myocardial infarction,stroke and revascularization(14.0%vs10.8%,P=0.014).After adjustment for comorbidities,anemia was associated with a higher risk of mortality after percutaneous coronary intervention(RR 2.216,95%CI 1.019-4.428;P=0.024).Conclusions Anemia is an independent predictor of mortality after PCI.Since PCI iS a common procedure and anemia is a frequent condition in the general population,strategies for the management of anemic PCI patients should be developed.

The disease incidence of aortic dissecting aneurysm showed an increasing tendency.Recently,the clinical application of endovascular stent-graft implantation received good results in treating aortic dissecting aneurysm,which is characterized by minimally invasive,safe,with high success rates.However,the chosen of anesthesia is still in dispute.Local anesthesia,intraspinal anesthesia and general anesthesia can be used in this operation.The investigation demonstrated that intubation general anesthesia is more security in this operation with less complication,which is conductive to controlling blood pressure and braking conditions.
