| 1 | Laparoscopic Partial Nephrectomy With Segmental Renal Artery Clamping:Technique and Clinical Outcomes显示文摘Background:Warm ischemic injury is one of the most important factors affecting renal function in partial nephrectomy(PN).The technique of segmental renal artery clamping emerges as an alternative to conventional renal artery clamping for renal hilar control.Objective:To evaluate the feasibility and efficiency of laparoscopic PN(LPN) with segmental renal artery clamping in comparison with the conventional technique.Design,setting,and participants:A total of 75 patients underwent LPN from June 2007 to November 2009.All patients had T1a or T1b tumor in one kidney and a normal contralateral kidney.Thirty-seven patients underwent surgeries with main renal artery clamping,and 38 underwent surgeries with segmental artery clamping.Intervention:All procedures were performed by the same laparoscopic surgeon.Measurements:Blood loss,operation time,warm ischemia(WI) time,and complications affected renal function before and after operation were recorded.Results and limitations:All LPNs were completed without conversion to open surgery or nephrectomy.The novel technique slightly increased WI time(p < 0.001) and intraoperative blood loss(p = 0.006),while it provided better postoperative affected renal function(p < 0.001) compared with the conventional technique.The total complication rate was 12%.Among the 38 cases where segmental renal artery clamping was performed,7 had to convert to the conventional method.Tumor size and location influenced the number of clamped segmental arteries.Long-term postoperative renal function is still awaited.Conclusions:LPN with segmental artery clamping is safe and feasible in clinical practice.It minimizes the intraoperative WI injury and improves early postoperative affected renal function compared with main renal artery clamping.(C) 2010 European Association of Urology.Published by Elsevier B.V.All rights reserved. | Shao,P.F.

| 3 | 塔里木盆地寒武纪—奥陶纪优质烃源岩沉积与古环境变化的关系:碳氧同位素新证据显示文摘对塔里木盆地东部塔东2井上震旦统和寒武系—奥陶系样品进行TOC和碳、氧同位素及微量元素分析,发现该井稳定碳、氧同位素值在寒武系—中奥陶统发生明显变化,该层还赋存高有机质丰度烃源岩,其TOC值的高低可反映当时的生物产率和埋藏率。碳和氧同位素值在寒武系/上震旦统分界处正向漂移,说明正好在进入寒武纪前气候明显变冷,海平面下降。接着,下寒武统底部以碳和氧同位素值的快速负向漂移为标志,表明古气候迅速变暖和海平面大幅度上升,烃源岩TOC值也达到全井柱最高值。古气候显著波动、海平面最高及其频繁变化和沉积物高TOC是早寒武世的显著特征;而晚寒武世—早奥陶世,同位素正向漂移,暗示海平面下降,沉积物TOC也随之下降并降至最低;到了早奥陶世末,即早、中奥陶世的过渡时期,同位素又开始负向漂移,TOC又开始升高;中奥陶世,同位素强烈负向漂移,TOC又升至新高。稳定碳、氧同位素值的变化及其所指示的古气候与海平面变化,以及与TOC的响应关系,指示冰期、冰后期之交,古气候迅速变暖和海平面大幅度上升有利于烃源岩发育;同时暗示,δ13C、δ18O与生烃母质生物的有机生产率、有机埋藏率之间存在某种内在联系。即高TOC含量反映高的有机生产率和高的有机埋藏率;而与其同步反方向变化的δ13C、δ18O则暗示海平面较高,沉积环境属远陆海域,表层水中生烃母质生物的光合作用很强。而有机质的高产率和高埋藏率,导致海水中δ12C和δ16O被大量地固定在沉积物中。这样,就使海水中相对富集13C和18O重同位素而使海水变“重”;而这种“重”海水,又导致了同时期浅水区碳酸盐沉积物的δ13C和δ18O值明显增高。 | 张水昌 R L WANG 金之钧 张宝民 王大锐 边立曾 | 2006 | 地质学报2006，80，3： | 65 |

| 5 | Staging accuracy of esophageal cancer by endoscopic ultrasound:A meta-analysis and systematic review显示文摘AIM: To evaluate the accuracy of endoscopic ultrasound (EUS) in the staging of esophageal cancer. METHODS: Only EUS studies confirmed by surgery were selected. Articles were searched in Medline and Pubmed. Two reviewers independently searched and extracted data. Meta-analysis of the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios, and diagnostic odds ratio. Pooling was conducted by both the Mantel-Haenszel method (fixed effects model) and DerSimonian Laird method (random effects model). The heterogeneity of studies was tested using Cochran’s Q test based upon inverse variance weights. RESULTS: Forty-nine studies (n = 2558) which met the inclusion criteria were included in this analysis. Pooled sensitivity and specificity of EUS to diagnose T1 was 81.6% (95% CI: 77.8-84.9) and 99.4% (95% CI: 99.0-99.7), respectively. To diagnose T4, EUS had a pooled sensitivity of 92.4% (95% CI: 89.2-95.0) and specificity of 97.4% (95% CI: 96.6-98.0). With Fine Needle Aspiration (FNA), sensitivity of EUS to diagnose N stage improved from 84.7% (95% CI: 82.9-86.4) to 96.7% (95% CI: 92.4-98.9). The P value for the χ2 test of heterogeneity for all pooled estimates was > 0.10. CONCLUSION: EUS has excellent sensitivity and specificity in accurately diagnosing the TN stage of esophageal cancer. EUS performs better with advanced (T4) than early (T1) disease. FNA substantially improves the sensitivity and specificity of EUS in evaluating N stage disease. EUS should be strongly considered for staging esophageal cancer. | Srinivas R Puli Jyotsna BK Reddy Matthew L Bechtold Daphne Antillon Jamal A Ibdah Mainor R Antillon | 2008 | World Journal of Gastroenterology2008，14，10： | 55 |

| 8 | Portal vein thrombosis, mortality and hepatic decompensation in patients with cirrhosis: A meta-analysis显示文摘AIM: To determine the clinical impact of portal vein thrombosis in terms of both mortality and hepatic decompensations(variceal hemorrhage, ascites, portosystemic encephalopathy) in adult patients with cirrhosis.METHODS: We identified original articles reported through February 2015 in MEDLINE, Scopus, Science Citation Index, AMED, the Cochrane Library, and relevant examples available in the grey literature. Two independent reviewers screened all citations for inclusion criteria and extracted summary data. Random effects odds ratios were calculated to obtain aggregate estimates of effect size across included studies, with 95%CI.RESULTS: A total of 226 citations were identified and reviewed, and 3 studies with 2436 participants were included in the meta-analysis of summary effect. Patients with portal vein thrombosis had an increased risk of mortality(OR = 1.62, 95%CI: 1.11-2.36, P = 0.01). Portal vein thrombosis was associated with an increased risk of ascites(OR = 2.52, 95%CI: 1.63-3.89, P < 0.001). There was insufficient data available to determine the pooled effect on other markers of decompensation including gastroesophageal variceal bleeding or hepatic encephalopathy. CONCLUSION: Portal vein thrombosis appears to increase mortality and ascites, however, the relatively small number of included studies limits more generalizable conclusions. More trials with a direct comparison group are needed. | Jonathan G Stine Puja M Shah Scott L Cornella Sean R Rudnick Marwan S Ghabril George J Stukenborg Patrick G Northup | 2015 | World Journal of Hepatology2015，7，27： | 42 |
| 9 | Role of surgery in colorectal cancer liver metastases显示文摘Colorectal carcinoma(CRC)is the third most common cancer,and approximately 35%-55%of patients with CRC will develop hepatic metastases during the course of their disease.Surgical resection represents the only chance of long-term survival.The goal of surgery should be to resect all metastases with negative histological margins while preserving sufficient functional hepatic parenchyma.Although resection remains the only chance of long-term survival,management strategies should be tailored for each case.For patients with extensive metastatic disease who would otherwise be unresectable,the combination of advances in medical therapy,such as systemic chemotherapy(CTX),and the improvement in surgical techniques for metastatic disease,have enhanced prognosis with prolongation of the median survival rate and cure.The use of portal vein embolization and preoperative CTX may also increase the number of patients suitable for surgical treatment.Despite current treatment options,many patients still experience a recurrence after hepatic resection.More active systemic CTX agents are beingused increasingly as adjuvant therapy either before or after surgery.Local tumor ablative therapies,such as microwave coagulation therapy and radiofrequency ablation therapy,should be considered as an adjunct to hepatic resection,in which resection cannot deal with all of the tumor lesions.Formulation of an individualized plan,which combines surgery with systemic CTX,is a necessary task of the multidisciplinary team.The aim of this paper is to discuss different approaches for patients that are treated due to CRC liver metastasis. | ?zgür Akgül Erdin? ?etinkaya ?iyar Ers?z Mesut Tez | 2014 | World Journal of Gastroenterology2014，20，20： | 40 |

| 11 | How good is endoscopic ultrasound for TNM staging of gastric cancers? A meta-analysis and systematic review显示文摘AIM: To evaluate the accuracy of endoscopic ultrasound (EUS) for staging of gastric cancers. METHODS: Only EUS studies confirmed by surgery were selected. Only studies from which a 2 × 2 table could be constructed for true positive, false negative, false positive and true negative values were included. Articles were searched in Medline, Pubmed, Ovid journals, Cumulative index for nursing & allied health literature, International pharmaceutical abstracts, old Medline, Medline nonindexed citations, and Cochrane control trial registry. Two reviewers independently searched and extracted data. The differences were resolved by mutual agreement. 2 × 2 tables were constructed with the data extracted from each study. Meta-analysis for the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specifi city, likelihood ratios, and diagnostic odds ratio. Pooling was conducted by both the Mantel-Haenszel method (fi xed effects model) and DerSimonian Laird method (random effects model). The heterogeneity of studies was tested using Cochran's Q test based upon inverse variance weights. RESULTS: Initial search identified 1620 reference articles and of these, 376 relevant articles were selected and reviewed. Twenty-two studies (n = 1896) which met the inclusion criteria were included in this analysis. Pooled sensitivity of T1 was 88.1% (95% CI: 84.5-91.1) and T2 was 82.3% (95% CI: 78.2-86.0). For T3, pooled sensitivity was 89.7% (95% CI: 87.1-92.0). T4 hada pooled sensitivity of 99.2% (95% CI: 97.1-99.9). For nodal staging, the pooled sensitivity for N1 was 58.2% (95% CI: 53.5-62.8) and N2 was 64.9% (95% CI: 60.8-68.8). Pooled sensitivity to diagnose distant metastasis was 73.2% (95% CI: 63.2-81.7). The P for chi-squared heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION: EUS results are more accurate with advanced disease than early disease. If EUS diagnoses advanced disease, such as T4 disease, the patient is 500 times more likely to have true anatomic stage of T4 disease. | Srinivas Reddy Puli Jyotsna Batapati Krishna Reddy Matthew L Bechtold Mainor R Antillon Jamal A Ibdah | 2008 | World Journal of Gastroenterology2008，14，25： | 33 |

| 16 | 直肠癌放化疗后观察等待与手术治疗的配对队列研究显示文摘目的近年对于直肠癌放化疗后临床完全缓解的患者出现了新的治疗模式。这类患者在新辅助治疗后不进行手术治疗而进行观察-等待(watch-and-wait)的随诊观察。本研究旨在通过对比放化疗后临床完全缓解的患者接受手术治疗和观察-等待方式两者的肿瘤学转归,研究观察-等待随诊方式的安全性。方法 On Co Re(直肠癌完全缓解病例肿瘤学转归)研究是在英国曼切斯特一所三级癌中心进行的配对队列研究。自2011年1月到2013年4月,收集所有年龄段、无远处转移且接受了术前化放疗(45Gy,25天,同期氟尿嘧啶化疗)的直肠腺癌病例。达到临床完全缓解的患者,进入观察-等待方式,而未获临床完全缓解的患者,在条件允许下接受手术治疗。本研究通过注册登记,同时纳入自2005年3月10日至2015年1月21日来自相邻区域的3所英国癌中心临床完全缓解而接受单纯等待-观察方式的直肠癌患者。研究采用采用1∶1配比队列,使用倾向得分匹配分析法(包括T分期、年龄和体力状态),比较患者接受单纯观察等待与手术切除的治疗转归。主要观察终点为自化放疗开始后无疾病进展生存,次要终点为总体生存以及结肠造口术后无瘤生存。本研究以更保守的P〈0.01视为差异具有统计学意义。结果共有259例患者来自曼彻斯特癌中心,228例接受手术治疗,而31例临床完全缓解患者单纯进行观察-等待。此外通过注册登记的98例患者也进入观察-等待组。观察-等待组共129位患者[中位随访33个月(IQR 19~43个月)],44例(34%)局部复发。41例无转移的局部复发患者中36例(88%)接受了补救性手术。配对分析显示(各109例),观察-等待组和手术组的3年无疾病进展生存无统计学差异[88%(95%CI 75~94)vs.78%(63~87),P=0.043]。同时3年总体生存也没有显著性差异(96%vs.87%,P=0.024)。观察-等待组的结肠造口率明显低于手术组,其3年结肠造口术后无瘤生存率为74%(95%CI 64~82),而手术组为47%(P〈0.0001)。风险比0.445(95%CI 0.31~0.63,P〈0.0001),观察-等待组较手术组的3年终生造口风险降低26%(95%CI 13~39)。结论本研究显示,确实存在一定比例的直肠癌患者可以通过观察-等待方式避免手术,免除终生造口,同时获得3年良好的肿瘤安全性。这结果提示,应从一开始就认真考虑直肠癌患者化放疗策略,观察-等待治疗作为标准治疗方式看来是可行的。研究者认为如果患者在化放疗开始后,少于14周内取得早期临床完全缓解,或者大于24周取得临床完全缓解,其复发的机会较少。此外,广泛使用45 Gy的放疗的患者的临床完全缓解率为10%~15%,更高剂量的放化疗能够将其提高到大于50%。如此高的临床完全缓解率如果能够在可接受的毒副作用范围内反复出现,那么以上两种策略就可以实现长期、持续的临床完全缓解。然而,这一观察结果还需要临床研究验证。 | Renehan AG Malcomson L Emsley R 张信华 | 2016 | 消化肿瘤杂志(电子版)2016，8，1： | 27 |
