Objective To discuss the clinicopathologic risk factors related to local recurrence of rectal cancer after radical surgery. Methods The complete clinicopathologic data of 368 patients with rectal cancer from January 2004 to April 2011 in this hospital were retrospectively analyzed by univariate and multivariate analysis methods. Results There were 73 cases suffered from local recurrence and accounted for 19.84% (73/368) of rectal cancer during the same period. Univariate analysis results showed that gender, tumor from anal margin, tumor circumference, TNM staging, histology type, vessel infiltration, tumor perforation, stomal leak, and chemoradiotherapy were associated with postoperative recurrence (P<0.05). Multivariate analysis results showed that tumor from anal margin, tumor circumference, TNM staging, histology type, vessel infiltration, tumor perforation, and chemoradiotherapy were prognostic factor for local recurrence of rectal cancer (P<0.05). Conclusions There are many factors related to postoperative local recurrence, but the most dangerous factor is vessel infiltration.
ObjectiveTo introduce the hiatal hernia (HH) and to summarize the research development of relationship between HH and respiratory symptoms. MethodsLiteratures in recent years which about relationship between HH and respiratory symptoms at home and abroad were collected and reviewed. ResultsGastroesophageal reflux disease (GERD), which always be caused by laryngeal airway and other esophageal symptoms, was a common illness and easily be misdiagnosed. One common symptom of the GERD was the HH. For those patients with reflux-associated esophageal symptoms, many of them suffered from HH. The treatment results showed that the endoscopic surgery could relieve the reflux symptom and effectively control the respiratory symptoms. ConclusionsThe HH can increase the risk of respiratory symptoms; an active treatment on the HH can relieve the respiratory symptoms, which is caused by the reflux symptom.
目的 探討大動脈炎所致腎動脈上腹主動脈閉塞的手術治療方法。方法 回顧性分析1例腎動脈上腹主動脈閉塞行腹主動脈-雙股動脈人工血管搭橋手術治療的患者的臨床資料,并進行文獻復習。結果 術后患者頭痛明顯好轉,血壓由術前的220/110 mm Hg(1 mm Hg=0.133 kPa)降至160/100 mm Hg,雙下肢踝肱指數由0.50升至1.19。術后2周復查CTA示人工血管通暢,術后3個月復查彩超示人工血管通暢,血壓在(140~150)/(80~95) mm Hg間波動,雙眼視力1.0左右,已恢復正常生活。結論 大動脈炎所致腎動脈上腹主動脈閉塞常會影響多個重要臟器的供血,病變復雜,手術時機及方法的正確選擇及長期抗炎治療可以提高患者的治療效果。
Objective To investigate the pathological features, diagnosis, treatment, and prognosis of multiple primary colorectal cancer (MPCC). Methods Clinical data of 41 patients with MPCC treated in The Fourth Affiliated Hospital and The First Affiliated Hospital of China Medical University from Aug. 1993 to Mar. 2009 were retrospectively analyzed. Results Forty one patients with MPCC, including 29 patients with synchronous colorectal cancer (SCC) and 12 patients with metachronous colorectal cancer (MCC), accounted for 1.8% (41/2 340) of colorectal cancer during the same period of time, and with adenomatous polyps in 19 cases and polyps canceration in 10 cases. Among 29 patients with SCC, 15 cases (51.7%) were diagnosed by preoperative fiberoptic colonoscopy, 9 cases (31.0%) were diagnosed by preoperative fiberoptic colonoscopy, abdomen CT, and barium enema, 5 cases (17.2%) were diagnosed by intraoperative exploration and intraoperative fiberoptic colonoscopy, respectively. All of the 12 patients with MCC were diagnosed by preoperative fiberoptic colonoscopy and abdomen CT. For 29 patients with SCC, tumor locations were from proximal appendix to distal rectum, but 12 patients with MCC were adverse. Sixty-five (77.4%) tumors were tubular or papillary adenocarcinoma, and 56 (66.7%) tumors were well and moderately differentiated adenocarcinoma. The TNM stage of most tumors (72) was stageⅡ or Ⅲ phase, account for 85.7%. Radical surgeries were performed in 37 patients and palliative surgeries in 4 patients, and there were no complications after operation. During the follow-up for 3-5 years (mear 3.6 years), the overall survival rate of 3- and 5-year were 48.8% (20/41) and 34.1% (14/41), respectively. In detail, 3-year survival rate of SCC group and MCC group were 48.3% (14/29) and 50.0% (6/12), respectively;5-year survival rate were 31.0% (9/29) and 41.7% (5/12), respectively. Conclusions Cause of MPCC has not been clear, but it has possible relationship with adenomatous polyps. Preoperative fiberoptic colonoscopy, abdomen CT, and barium enema are very important for patients with SCC, and intraoperative fiberoptic colonoscopy is also necessary. Patients with MCC should enhance postoperative follow-up with fiberoptic colonoscopy. Further more, radical resection should be performed as early as possible.
目的 研究胃癌細胞SGC-7901培養上清液及轉化生長因子-β1(TGF-β1)是否可促進人類腹膜間皮細胞表達βig-h3蛋白。方法 培養胃癌細胞SGC-7901,取第3天培養液上清與DMEM培養液的混合液 (1∶4)以及0、1.0、10.0和50.0ng/ml的 TGF-β1分別刺激人類腹膜間皮細胞HMrSV50、3、6、12及24h,ELISA方法檢測上清液中βig-h3蛋白濃度,Western blot法檢測細胞內βig-h3蛋白濃度。結果 對照組有基礎量的βig-h3蛋白表達; 胃癌細胞SGC-7901培養上清液及TGF-β1均可明顯增加HMrSV5細胞上清液及細胞內的βig-h3蛋白濃度(P<0.05),且TGF-β1的刺激作用呈時間及濃度依賴性。結論 胃癌細胞SGC-7901培養上清液及TGF-β1可明顯刺激HMrSV5細胞表達和分泌βig-h3蛋白。
