ObjectiveTo investigate clinical outcomes and risk factors of patients with valvular heart disease (VHD) and giant left ventricle undergoing heart valve replacement (HVR). MethodsClinical data of 144 VHD patients with giant left ventricle who underwent HVR in Union Hospital of Tongji Medical College, Huazhong University of Science and Technology from January 2009 to December 2012 were retrospectively analyzed. There were 116 male and 28 female patients with their age of 15-69 (44.9±11.9) years and disease duration of 57.8±98.3 months (range, 1 month to 40 years). There were 92 patients with rheumatic VHD, 28 patients with degenerative VHD, 15 patients with congenital VHD, and 9 patients with infective endocarditis. A total of 137 patients who were discharged alive were followed up. Risk factors of postoperative mortality, morbidity and late death of VHD patients with giant left ventricle undergoing HVR were analyzed with t-test, chi-square test or Fisher's exact test, and logistic regression analysis. The life-table method was used to calculate long-term survival rate and draw the survival curve. ResultsMajor postoperative complications included low cardiac output syndrome (LCOS) in 19 patients (13.2%), ventricular arrhythmias in 56 patients (38.9%), prosthetic paravalvular leaks in 7 patients (4.9%), pleural effusion in 33 patients (22.9%), pericardial effusion in 8 patients (5.6%), liver failure in 23 patients (16.0%), and renal failure in 5 patients (3.5%). Seven patients (4.9%) died postoperatively. Logistic univariate analysis showed that advanced-age ( > 50 years), rheumatic VHD, higher preoperative NYHA class (Ⅲ or Ⅳ), long disease duration, poor preoperative left ventricular function[left ventricular ejection fraction (LVEF) < 40%], double valve replace-ment (DVR), other concomitant intracardiac procedures, prolonged cardiopulmonary bypass (CPB) time and aortic cross-clamping time, postoperative LCOS and ventricular arrhythmias were risk factors of early mortality of VHD patients with giant left ventricle undergoing HVR (P < 0.05). Logistic multivariate analysis showed that advanced age ( > 50 years), long disease duration, higher preoperative NYHA class (Ⅳ), poor preoperative left ventricular function (LVEF < 40%), DVR, prolonged CPB time were independent predictors of early mortality (P < 0.05). Logistic multivariate analysis showed that higher preoperative NYHA class (Ⅲ or Ⅳ), other concomitant intracardiac procedures, poor preoperative left ventricular function (LVEF < 50%) were independent predictors of postoperative LCOS (P < 0.05). Higher preoperative NYHA class (Ⅲ or Ⅳ) and preoperative non-sinus rhythm were independent predictors of postoperative ventricular arrhy-thmias (P < 0.05). Within 2 weeks after the operation, left ventricular end-diastolic dimension (LVEDD), left atrial diameter (LAD), LVEF and left ventricular fractional shortening (LVFS) were all significantly reduced compared with preoperative parameters (P < 0.05). Five patients died during follow-up. One-year, 2-year, 3-year and 4-year survival rates were 97.1%, 95.0%, 92.7% and 92.7% respectively. Preoperative LVEF, LVEDD and NYHA were significantly different between patients who died or survived during follow-up. ConclusionsHVR can produce low postoperative mortality, high long-term survival rates and satisfactory clinical outcomes for VHD patients with giant left ventricle. Advanced age ( > 50 years), long disease duration, higher preoperative NYHA class (Ⅳ), preoperative non-sinus rhythm, poor preoperative left ventricular function (LVEF < 40%), DVR and prolonged operation time may be risk factors of postoperative mortality and morbidity. Poor preoperative left ventricular function and significantly enlarged left ventricle may be risk factors of late death after HVR.
【Abstract】ObjectiveTo investigate the effects of high molecular bio-degradable film on preventing peritoneal adhesion. MethodsOne hundred and twenty rats were divided into control group, non-bio-degradable film group and polycaprolactone (PCL) group. Animal models of peritoneal adhesion made by operations on rats serve as control group. In the study, non-bio-degradable film and biodegradable, namely PCL films sensitive to pseudomonas enzyme, were put into the opening of peritoneum. The effect of the films on peritoneal adhesion was examined on 1, 3, 7 and 30 d after operation. ResultsPeritoneal adhesion was found in all the rats of control group and very low in PCL group and non-bio-degradable film group. ConclusionPCL film can effectively prevent the formation of postoperative peritoneal adhesion.
目的 探讨胆道术后肝内、外胆管狭窄的治疗方法。方法 回顾性分析吉林大学第一医院自2003年1月至2007年12月期间应用胆道镜对37例胆道术后肝内、外胆管狭窄患者行气囊扩张治疗的结果。结果 本组37例患者42处肝内、外胆管狭窄均行胆道镜下气囊导管扩张，29例（78.4%）系胆管狭窄伴肝内胆管结石，经气囊扩张后，胆道镜通过狭窄部位，取净远端胆管结石； 另8例（21.6%）系单纯胆管狭窄无结石,仅行导管扩张。本组成功率达97.3%（36/37）； 1例因胆汁性肝硬变伴弥漫性胆管狭窄扩张失败后行肝叶切除手术。27例狭窄仅需一次性扩张,9例因胆管多处严重狭窄而行多次扩张。全部患者均获随访，随访时间6~24个月,平均12个月，未见结石复发。结论 胆道镜下气囊导管扩张治疗胆管狭窄微创、直观、安全、简便易行且疗效可靠,是治疗胆管狭窄并取净结石的理想方法。但需注意操作方法及技巧，防止并发症的发生。

ObjectiveTo explore the effectiveness of self-made adjustable tractor for correction of inverted ni pple. MethodsBetween March 2005 and March 2011, 37 female patients with inverted ni pples (69 ni pples) underwent continuous traction with self-made adjustable tractor for 2 to 4 months. The age ranged from 18 to 46 years (mean, 23 years). Of 37 cases, 5 had unilateral inverted ni pple, and 32 had bilateral inverted ni pples, including 8 cases (15 ni pples) of mild inversion, 16 cases (30 ni pples) of moderate inversion, and 13 cases (24 ni pples) of severe inversion. The 2 cases (4 ni pples) recurred after traditional surgical method, and 1 case (2 ni pples) had infection because of severe inversion before traction. ResultsNo infection or hemodynamic disorder occurred during traction. All cases were followed up 6-12 months (mean, 8.2 months). Wound healed after traction in 1 patient (2 ni pples) with infection because of severe inversion; 2 recurrent cases (2 ni pples) were cured after re-traction; wire dislocation occurred in 1 case (1 ni pple), and was cured after changing traction position. The shape, sensation, and erectile function were normal after treatment with no scar. ConclusionContinuous traction with selfmade adjustable tractor is a good method for all the types of inverted ni pple. It is a simple, safe, effective, and minimally invasive method without scar.
ObjectiveTo systematically review the effectiveness and safety of taxanes combined with cisplatin and fluorouracil (TFP) versus cisplatin and fluorouracil (FP) for locally advanced head and neck squamous cell carcinoma. MethodsDatabases such as The Cochrane Library (Issue 1, 2013), PubMed, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data were electronically searched to collect randomized controlled trials (RCTs) about taxanes combined with cisplatin and fluorouracil in the treatment of locally advanced head and neck squamous cell carcinoma from the date of their establishment to April 1st, 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2 software. ResultsA total of 7 RCTs involving 2 088 patients were included. The TFP group included 1 051 cases, while the FP group included 1 037 cases. The results of meta-analyses showed that, there were significant differences between the two groups in the 1-year, 2-year, and 3-year overall survival rates (RR=1.12, 95%CI 1.02 to 1.23, P=0.02; RR=1.20, 95%CI 1.11 to 1.29, P < 0.000 01; RR=1.18, 95%CI 1.07 to 1.31, P=0.000 7), the 1-year, 2-year, and 3 year of progressions free survival (RR=1.18, 95%CI 1.08 to 1.28, P=0.000 2; RR=1.20, 95%CI 1.06 to 1.36, P=0.003; RR=1.48, 95%CI 1.25 to 1.74, P < 0.000 01), the complete remission rate (RR=1.67, 95%CI 1.26 to 2.23, P=0.000 4), and the overall response to chemotherapy (RR=1.18, 95%CI 1.11 to 1.27, P < 0.000 01). As for the side effect, the FP group was superior to the TFP group in the neutropenia (RR=1.42, 95%CI 1.24 to 1.63, P < 0.000 01), alopecia (RR=16.09, 95%CI 4.59 to 56.38, P < 0.000 1), and febrile neutropenia (RR=2.21, 95%CI 1.29 to 3.80, P < 0.004). ConclusionThe fluorouracil with cisplatin and fluorouracil for advanced head and neck squamous cell carcinoma might have better effects, but with higher side effects.
