Objective To explore the clinical features of sentinel polyps (rectal polyps with proximal colon carcinoma) and its correlation with proximal colon carcinoma.Methods From January 2011 to June 2015,the clinical features of 331 hospitalized patients with rectal polyps were retrospectively analyzed.According to whether the patient with colon carcinoma,the clinical data of rectal polyps patients were divided into pure polyps group (n =294) and sentinel polyps group (n =37).The characteristics under endoscopy,clinical pathological features,treatment and prognosis of two groups were observed.Results The positive rate of tumor marker of sentinel polyps group was higher (67.6 ％,25/37) than that of pure polyps group (6.8 ％,20/294;x2 =32.174,P ＜ 0.01).When compared to pure polyps group,most polyps of sentinel polyps group were in maximum diameter over 1 cm [62.2％ (23/37) vs 46.9 ％ (138/294)],multi-polyps [n ＞5,43.2％ (16/37)vs11.6％ (34/294)] and adenomatous polyp [83.8 ％ (31/37) vs 35.7 ％ (105/294)] (x2 =10.863,15.686,and 22.653,P ＜0.01).Majority of the proximal colon carcinoma with rectal polyps was papillary adenoearcinoma and tubular adenocarcinoma which was account for 75.7 ％ (28/37);Duke A,29.7％ (11/37),Duke B,29.7％ (11/37),Duke C,24.3％ (9/37) and Duke D,16.2％ (6/37).96.6 ％ (282/294) of patients with pure polyps underwent endoscopic treatment and all of them were cured and discharged.40.5％ (15/37) of patients of sentinel polyps group accepted the radical operation and 24.3％ (9/37) received endoscopic submucosal dissection.Conclusions If multiple,maximum diameter over 1 cm and adenomatous rectal polyps were detected under colon endoscope,the possibility of carcinogenesis of the polyps or the proximal colon should be aware.The patient should be followed up in short-term and complete the whole colon examination.

Primary CNS lymphoma (PCNSL) is a rare malignancy with peculiar clinical and biologic features,aggressive course,and unsatisfactory outcome.the particular microenvironment of this malignancy,and sanctuary sites where tumor cells grow undisturbed, strongly affects treatment efficacy. The execution of prospective trials is also difficult because of the rarity of the tumor and the impaired general condition and poor performance status of patients. Chemotherapy is indispensable for the treatment of PCNSL. High-dose methotrexate is the most effctive drug.PCNSL is sensitive to irradiation,but responses to radiotherapy alone are short-lived. MTX-based chemotherapy followed by whole-brain radiotherapy prolonged survival but is associated with delayed neurotoxicity especially in patients older than 60 years. A new approach is attempted to treat PCNSL with chemotherapy alone with defered radiotherapy in old patients with similar survival rencenfly. High-dose chemotherapy with autologous stem cell transplantation HDC/ASCT yielded promising results for recurent PCNSL.Clinical investigation with Temozolomide or rituximab have been reported.Further studies with these new drugs are needed.

Objective: To investigate the expression of Notch1 and NF-κB in gastric cancer and discuss the association between the expressions of both and their relationship with the clinicopathological features. Methods: The expression of Notch1 and NF-κB in 168 specimens of gastric cancer and 27 specimens of normal gastric tissues were detected by SP immunohistochemistry. Results: The expression of Notch1 was significantly upregulated in gastric cancer as compared with normal gastric tissues (P < 0.0 1). It was closely related with tumor size, differentiation grade, depth of invasion, and vessel invasion. The expression of NF-κB in gastric cancer was remarkably higher than that in control group (P < 0.01) and was significantly associated with tumor size, differentiation degree, depth of invasion, distant metastasis, and vessel invasion. Kaplan-Meier analysis showed that Notch1- and NF-KB positive patients had poor prognosis than Notch1- and NF-κB-negative patients. Cox regression multivariate analysis showed that Notch1 was one of the independent prognostic factors for gastric cancer (P <0.05). Conclusion: The over-expression of NF-κB may be involved in the carcinogenesis and progression of gastric cancer mediated by Notch1 signaling pathway. Notch1 may become a potentially useful marker for evaluating the prognosis and survival of gastric cancer and a new therapeutic target.

Objective To study the feasibility of the treatment of tubule pregnancy by interventional technique. Methods By using Seldinger′s method, 40 cases of tubule pregnancy received superselective angiography of uterine artery,followed by perfusion of methotrexate (MTX) through the catheter and embolization of uterine artery with gelatin sponge. The concentration of serum ? HCG, the change of pelvic cavity, and the open condition of oviduct were regularly monitored postoperatively. Results Angiographic findings of tubule pregnancy were classified into 3 types. Type Ⅰ, no abnormal vascular appearance were found in 3 cases (7.5%). Type Ⅱ, patchy vascular staining of villi in parauterine area was observed in 4 cases (10.0%). Type Ⅲ, a round vascular staining of villi surrounded by small blood vessels in parauterine area occurred in 33 cases (82.5%). The cure rate in total 40 cases achieved 97.5% (39/40). After treatment, the mean time that the serum ? HCG concentration returned to normal was (7.66?2.01) d and the mean time that the menstruation returned to normal was (29.78?7.14) d. In 21 cases who hoped their fertility remaining intact, the oviduct were verified open by hysterosalpingography (HSG) in 20 cases, the open rate was 95.24%. Conclusion The treatment of tubule pregnancy by interventional technique was proved no harmful effect to reproductive organs and would expect to preserve fertility. This method could resolve the difficult problem of celiac hemorrhage which making conservative treatment impossible and internal hemorrhage happened in the course of traditional conservative therapy leading to treatment failure finally. This method might be a new conception and a choice to treat tubal pregnancy through artery.

Objective Cavernous hemangioma of infant was reported as an obscure diagnosis with the different sensitivity to corticosteroid therapy and various natural courses. Therefore, a clinical studies for the biological classification of deep subcutanious vascular lesions might be needed, which was alluded by Mulliken two decades ago. Methods Infants with cavernous hemangiomas accepted normal system corticosteroid therapy during the first 6 months of life before eight-year-follow-up, which continued until the children were 9 to 10 years old. The expression of PCNA and bFGF, and cellular histological characteristics were observed in 12 cases by biopsy. Results There were two major categories of subcutaneous vascular lesions groups: deep capillary hemangiomas, a lesion regressing slowly, and venous malformation, a lesion growing commensurated with the child. They will be also distinguished on the basis of diverse final treatment results, expression of cellular markers, microscopical characteristics, and physical signs. Conclusion The new classification appears to be helpful to make the choice of therapy for infants with "cavernous hemangiomas" , which is proven to be a terminologic confusion.
