Laterally spreading tumor is a new type of colorectal tumor found recently.For its particular shape and develptment of tumor,LST is divided as an independent tumor.LST is associated with colorectal cancer and more research is done on it .The progress of its epidemiology, oncomolecularbiology, diagnosis and therapy is reviewed.

Aim To investigate roles of ROS in oxaliplatin-induced PUMA expression and apoptosis in colon cancer cells.Methods ROS was used as an oxidative stress in vitro and PUMA expression was determined by Western blot analysis,the apoptosis induced by ROS was assessed by Hoechst 33258 dye staining,the proliferation of the colon cancer cells treated with oxaliplatin and antioxidant was determined by MTT assay.Results ROS induced apoptosis and PUMA expression in colon cancer cells;suppression of PUMA expression by stable transfecting PUMA anti-sense vector decreased apoptosis induced by ROS;oxaliplatin-induced PUMA expression was abrogated by antioxidant and the proliferation of colon cancer cells treated with oxalipla-tin was increased by antioxidant.Conclusions Our data suggests that PUMA and ROS play important roles in oxaliplatin-induced apoptosis.Oxaliplatin induces PUMA expression and apoptosis partly through ROS in colon cancer cells.

AIM:To enhance the doctors` ability of disease diagnosis and treatment by using standardized patients in neuro-ophthalmology teaching.METHODS: Graduated students and visiting students accepting neuro-ophthalmology training courses in Department of Ophthalmology during 2014-2016 were enrolled as the research objects.Two groups were randomized allocated and 20 students each group.One group of students was applied standardized patients teaching method and the other group of students was applied traditional teaching method.A questionnaire and exam after the teaching were evaluated.The data were analyzed by SPSS 20.0.RESULTS: The data of questionnaire included content interest improving,satisfaction for teaching,the key points understanding,theory with practice effective linking,future practice instruction.Comparison questionnaire data between two groups were of statistical significance (P<0.05).The test scores of case analysis of two groups were statistically significant also(P<0.001).CONCLUSION: Standardized patients teaching method is helpful for students` training on the ability of clinical diagnosis and treatment.

Radiotherapy plays a crucial role in cervical cancer.Intensity modulated radiation therapy is widely used gradually,which allows the photon beam within each field to be modulated and therefore improves the dose distribution by maximizing target coverage and minimizing the damage to normal tissue.Concurrent radiochemotherapy plus brachytherapy are standard therapeutic methods for local advanced cervical cancer.

Objective To retrospectively review the experience of esophageal manometry and 24-hour pH monitoring in esophagus surgery. Methods From 1982 to 2010, patients with unspecific chest pain and undergone esophageal surgery were received esophageal manometry and 24-hour pH monitoring. Results Among the patients with unspecific chest pain, 70.4%(74/105) were diagnosed as esophageal origin. Lower esophageal sphincter pressure (LESP) can be continuously maintained by using 360° fundoplication. Only a minority of patients who underwent transabdominal esophagocardiomyotomy and partial posterior fundoplication had acid reflux postoperatively. Incidence rate of achalasia of upper esophageal sphincter (UES) and pharyngeal "shoulder wave" in side-to-side stapled anastomosis is significantly lower than in traditional hand-sewn anastomosis,as well as contractive pressure in anastomosis region and occurrence of swallow discomfortableness. There is a high pressure region at the esophageal entrance in patients with bilateral platysma muscle flap for cervical esophagus defect following removal of hypopharynx cancer. And the pressure of the region is significantly lower than in healthy controls. Basal pyloric pressure and peak pressure of pylorus in phase Ⅲ of the migrating motor complex increased significantly after gastric conduit was made and anastomosed, but decreased appreciably following pyloric digital fracture. Peak pressure, frequency and duration time of isolated pyloric pressure wave ( IPPW ) decreased after pyloric digital fracture significantly. Conclusion Esophageal manometry and 24-hour pH monitoring are important tools for and diagnosing unspecific chest pain and evaluating the outcome of new surgical procedures.

Objective To investigate the identification of MiR-221 regulates apoptosis by targeting PUMA in lung cancer. Methods The express levels of miRNAs that collected from lung cancer tissue and lung benign lesion were tested by the particular kid they made,analyzed the correlation between individual miRNA.Results 9 6 possible regulated PUMA related miRNAs had been screened through the bioinformatics database,then customized it into the special kit to test the expression with real time fluorescent PCR.The results showed that 10 types miRNAs were up expression in lung cancer tissue,miR-NA221 were selected for deep analyze.Results with rank sum test showed statistical significance (P<0.05)in lung cancer and para cancer tissue.There were statistically significant differences in the expression between metastasis and nonmetastasis (P<0.05),but had nothing to do with the pathological types.Conclusion Real time fluorescent PCR test showed several types of PUMA related miRNAs up-expressed in tissue lung,which indicate miRNA have relationship with PUMA in gene express regulation and cancer generation and development.Pression situation and clinic pathological parameters.Expression of miRNA-221 in lung cancer was associated with tumor metastasis.

The treatment plan of facial neuritis in Evidence-based Guidelines of Clinical Practice in Acupuncture and Moxibustion (2011 edition) is discussed, and case information of facial neuritis during the recent five years in department of acupuncture and moxibustion, PLA General Hospital, is retrospectively analyzed. In accordance with anatomy of the facial nerve to form the acupuncture prescription, the detailed diagnosis and treatment method for facial neuritis are introduced. The advantages of the diagnosis and treatment method for facial neuritis are summarized, hoping to establish a more comprehensive, standardized and unified treatment plan.

100% elevation of PKC activity in the retina, and administration of D ? tocopherol prevented the elevation of PKC activity and diabetes induced decrease of both Na + K + ATPase and Ca 2+ ATPase activities. D ? tocopherol achieved a complete prevention of augmented pericyte and endothelial cell profile areas and basement membrane thickening in the superficial and deep capillaries bed of diabetic retina but had no effect on blood glucose and HbA 1c . Conclusion Diabetes induced histopathological abnormalities are mostly mediated by PKC. D ? tocopherol reduces the ultrastructural lesions in retinal capillary bed induced by hyperglycemia.

Objective To study the value of insulin like growth factor binding protein-1 of cervicovaginal secretion in the delayed pregnancy termination. Methds Phosphorylated isoforms of IGFBP-1 in cervicovaginal secretion of 202 delayed pregnant women were measured by immmmunochromatography. Results In the IGFBP-1 positive group. The rate of successful pregnant termination in three days was 91 2%, while in IGFBP-1 negative group, the rate of that was 41 8%..There was statistically significant diference in the rate of successful pregnant termination between the two groups(P

Objective To explore the diagnosis criterion of acute and chronic radiation oral mucositis induced by ionazition correctly. Methods 40 patients who were given radiotherapy because of head-neck cancer and 40 patients who were irradiated in the whole body for hematogenic stem cell transplant pretreatment were observed and analyzed. They were diagnosed by symptom and sign. Results 28 patients who were given radiotherapy were found acute oral mucous membrane change when cumulate radiation dose attained 30 Gy. The incidence of acute radiation oral mucositis was 70 percent. 20 TBI patients were found oral ulcer in 7 to 8 Gy radiation dose. The incidence of oral ulce was 50 percent. Conclusion The advance limit of irradiated dose for acute and chronic radiation oral mucositis are 20～30 Gy and 50～60 Gy.
