1. 5 cm) sessile colorectal polyps referred for EMR. After submucosal injection of epinephrine, either en bloc or piecemeal snare polypectomy were performed. All resected specimens were retrieved for pathologic study. Follow-up colonoscopy was performed in all patients after EMR. Results All 157 polyps were removed completely. All lesions are larger than 1. 5cm, but 3 less than 1 cm on the submucosa of rectum. The largest one is 13 cm X 12 cm. No complication occurred. Histopathologic assessment of the resection specimens revealed the following: adenoma, 123; dysplasia, 80; mucosal carcinoma, 11; hyperplastic polyps, 20; rectal carcinoid, 3. Two patients who had rectal adenoma that was larger than 7cm recurrence happened at the resection site after 1 and 3 months follow-up respectively, than removed completely by hot biopsy forceps showed hyperplastic and villous adenoma on pathological study. No more residual tumor was detected for 6-12 months. Conclusion EMR with an intensive follow-up program is a safe and effective treatment for large sessile colorectal polyps and mucosal carcinoma.

Objective To summarize the experience in diagnosis and therapy of familial adenomatous polyposis with desmoid tumour. Methods Clinical data of 6 patients with familial adenomatous polyposis and desmoid tumour from Jan 1989 to Jan 2005 were retrospectively analyzed. Results Five patients received proctocolectomy and 1 abdominoperineal resection. The most common symptom was progressive painless mass in abdomen. All patients were confirmed by image examination. Four received surgery, 2 were treated by medicine postoperatively and 1 got watchful therapy. Postoperative recurrence developed in two cases and one suffered from short bowel syndrome. All patients were alive at the follow-up. Conclusions FAP with desmoid tumour is not a rare condition and we should pay attention to diagnosis and manage this disease entity. A reasonable remedy was selected according to general state of health and location of desmoid tumour which can improve prognosis and quality of life.

ObjectiveTo discuss the incidence,endoscopic manifestion and pathological features of the upper-gastrointestinal polyps ( stomach and deodenum) in FAP patients. MethodsDuring 2004 -2010 a total 57 FAP patients at Changhai Hospital underwent screening for polyps in upper-gastrointestinal tract by gastroscopy and sideward-viewing duodenoscopy. Biopsies were taken on the polypoid lesions.ResultsGastric polyps were found in 38 patients (67%).Most polyps were located at gastric body and antrum,the pathologic diagnosis was hyperplastic. Duodenal polyps were found in 12 patients (21%) including 7 cases of adenomatous polys. ConclusionsUpper- gastrointestinal polyps are the most common extra-colonic manifestion in FAP. Most stomach polyps are located at gastric body and antrum and are hyperplastic.Polyps at duodenum may be adenomatous,which is a precusor of carcinoma.
5.Mechanism exploration and future prospects of antiangiogenic agents improving tumor blood supply and oxygenation.
Chinese Journal of Gastrointestinal Surgery 2014;17(11):1148-1151
The growth and metastasis of tumor is angiogenesis-dependent. Antiangiogenic agents have been clinically used to treat malignant tumors with the mechanisms of regressing tumor vasculature and inhibiting vascular recurrence which restrain tumor growth and metastasis. Clinical evidences indicate that antiangiogenic agents combined with chemotherapy or radiotherapy potentiate the effects of treatment. However, radiation therapy and chemotherapy depend on ample blood flow to the tumor to deliver oxygen and drugs. Theoretically, it is paradoxical with evidences that these therapies work together rather than against each other. "Vascular normalization" theory was raised to explain this paradox. And accumulating data show that antiangiogenic agents transiently "normalize" tumor vasculature before causing vascular regression, so that improve tumor blood supply and increase tissue oxygenation. New views and challenges about antiangiogenic agents come out with the discovery of "normalization window". In this review, we summarized the mechanism, related researches and future prospects of antiangiogenic agents improving blood supply and oxygenation.

Objective To study the distribution characteristics of deposited eggs and pathological changes in the viscera of animal infected with Schistosoma japonicum at different time. Methods New Zealand white rabbits were infected artificially with quantitative S. japonicum miracidia,then the distribution characteristics and the hatchability of schistosome eggs as well as the pathological changes of the corresponding viscera of the rabbits 42 and 60 d post?infection were observed and compared. Re?sults On the 42nd day post?infection,among all the viscera observed,the percentage of eggs deposited,the number of eggs per gram and the hatchability were the highest in the liver,while on the 60th day post?infection,the tissues and organs with the highest values of the above 3 indexes were the liver,rectum and upper section of the small intestine,respectively. From 42 day to 60 day post?infection,the liver of infected rabbits became swelling,hardening and lost elasticity,the color changed from black to dark grey,and egg nodules gradually appeared in the different sections of the small intestine,and also the mucosal hy?peremia,edema and egg nodules were seen in the colon,cecum and rectum. The lesion levels tended to be correlated with the deposition of eggs. Conclusion The amount and the density as well as the hatching rate of deposited eggs of S. japonicum in the viscera of infected rabbits at different time are different,and the lesion level in the host is correlated with the deposition of eggs.

OBJECTIVETo investigate the microRNA101(miR101) expression and its clinical significance in colorectal cancer.
METHODSTissue microarrays containing 56 specimens of normal mucosa, 51 adenoma and 735 colorectal cancer were examined by locked nucleic acid in-situ hybridization(LNA-ISH) for miR101 expression. Relationship between miR101 expression and clinicopathologic parameters and prognosis of colorectal cancer patients were analyzed. Fresh frozen tissues containing 5 specimens of normal mucosa, 5 adenoma and 47 colorectal cancer were examined by RT-PCR to verify the accuracy of LNA-ISH.
RESULTSExpression of miR101 increased gradually from normal mucosa, adenoma to stage I colorectal cancer (all P<0.01), and decreased gradually from stage II(, stage III( to stage IIII( colorectal cancer (all P<0.01). Overexpression of miR101 was related with lower incidence of lymph node metastasis, lower metastasis rate, higher differentiation and lower recurrence rate (all P<0.01). Multivariate survival analysis demonstrated that miR101 expression was an independent prognostic factor of overall survival (HR=0.550, 95% CI: 0.351-0.863) and disease free survival(HR=0.562, 95% CI: 0.397-0.794) in colorectal cancer patients. Overexpression of miR101 predicted a better prognosis in colorectal cancer patients.
CONCLUSIONSExpression of miR101 is associated with the genesis and development of colorectal cancer, and may serve as an independent prognostic factor for colorectal cancer patients.

We report a case of port-site metastasis after laparoscopic surgery for early stage uterine carcinosarcoma (UCS) and review the related literature. A 53-year-old woman with suspected uterine malignance underwent a total laparoscopic hysterectomy with bilateral salpingo-oophorectomy, infra-colic omentectomy, and pelvic lymphadenectomy resulting pathologically in a stage IA UCS. Twelve months later she developed a palpable abdominal-wall mass at the trocar site without other synchronous metastases. A mass resection was performed and it was pathologically diagnosed with port-site metastasis of UCS. When performing surgery for UCS, specimens should be carefully removed in case small pieces of the occult disseminated metastatic tissues are trapped between the outer surface of the trocar sleeve and the abdominal wall incisional canal. Despite the low incidence, a laparotomy might be considered rather than laparoscopy to prevent port-site metastasis and more gynecological oncology clinical practices might be relevant to the management of port-site metastasis.

OBJECTIVETo screen long non-coding RNA (lncRNA) associated with radiosensitivity in colorectal carcinoma cell lines.
METHODSColony formation assay was performed in colorectal cancer cell lines HT29, SW480, RKO, Lovo and HCT116 after irradiation with different radiation doses. Radiation sensitivity of these 5 cell lines was detected through survival fraction at 2 Gy (SF2 value). High-throughput lncRNA chip was used to screen lncRNA genes with expression differences more than 2 folds among SW480, RKO and Lovo. Further experiment on the expression differences of lncRNAs selected was conducted by realtime PCR.
RESULTSThe radiosensitivity order of these 5 cell lines from low to high (SF2 value from high to low) was HT29 (0.83 ± 0.03), SW480 (0.69 ± 0.02), RKO(0.53 ± 0.02), Lovo (0.47 ± 0.05), HCT116 (0.32 ± 0.03) (P < 0.01). Five lncRNAs associated with radiation sensitivity were screened. Among them, expression levels of R05532, NR_015441, and NR_033374 were positively correlated with radiation resistance(all P < 0.01), and expression levels of the other 2 lncRNAs, NR_073156 and AA745020, were not correlated with radiation resistance of colorectal cancer cells (both P>0.05).
CONCLUSIONSlncRNA R05532, NR_015441 and NR_033374 may be used as the predictive marker of radiosensitivity of colorectal cancer cells. Higher expression of these genes shows radiation resistance.
