Objective The aim of this study was to reveal the clinical features of colorectal polyps by investigating its endoscopic features using a magnifying videoscope. Methods One hundred and five colorectal polyps presented in colonoscopy were included in this study. A magnifying videoscope with a zoom ranging from ? 1 to ? 100 magnification combined with indigocarmine dye was employed to observe the pit pattern of colorectal polyps. Pit pattern was analyzed according to Kudo' s modified classification as follows; (1) type Ⅰ ; round pit; (2) type Ⅱ; asteroid; (3) type Ⅳs; tubular or round pit, which is smaller than the normal pit (type Ⅰ ) ; (4) type ⅢL: tubular or round pit, which is larger than the normal pit (type Ⅰ ) ; (5 ) type Ⅳ : dendritic or gyrus - like pit; ( 6 ) type Ⅴ : irregular or amorphous pit; and ( 7 ) mixed type. Types Ⅰ and Ⅱ represented the pit pattern of nonneoplastic polyps and types Ⅲ L , Ⅲs, Ⅳ , Ⅴ , and mixed type represented the adenomatous polyps represented neoplastic polyps. Results In all samples of polyps, 17 were of the pedunculated type, 40 subpedunculated type and 48 sessile type. Among the 17 pe-dunculated type, 12 were type Ⅰ ,Ⅱ pit pattern. In those subpedunculated types, type Ⅰ , Ⅱ pit pattern were found in 15. 0% (6/40) , type ⅢL , Ⅲs , Ⅳ, and Ⅴ were detected in 85. 0% (34/40) . Type Ⅰ ,Ⅱ pit pattern were found in 41. 7% (20/48), type Ⅰ,ⅢL, ⅢS, Ⅳ, and V were in 58.3% (28/48) in sessile type. Of all polyps 88 (83. 8% ) were situated between the splenic flexure and rectum , but'no correlation was found between pit pattern and location of polyps. The incidences of neoplastic changes in the lesions with pit pattern Ⅰ,Ⅱ ,ⅢL, Ⅲs,Ⅳ, Ⅴ , and mixed type were 0% , 11. 8% , 77. 3% , 75. 0% , 100. 0% , 100. 0% , and 70. 0% , respectively. The diagnostic sensitivity of neoplastic and nonneoplastic polyps were 96. 7% and 80. 0% , and specificity were 86. 6% and 94. 7% . The overall diagnostic accuracy in differentiating neoplastic from nonneoplastic polyps was 89. 5% . Conclusions The pit pattern analysis of colorectal polyps by magnifying colonoscopy combined with indigocarmine staining is a useful and objective tool fur differentiating nonneoplastic lesions from adenomas or invasive carcinoma of the large bowel. There-fore it may be possible to determine, at the lime of colonoscopy, which lesions require treatment or not, and which one should be removed by endoacopy, or by surgery.

This paper summarizes the systematic management of artificial airway for 36 postoperative patients with laryngeal cancers. A full-time nurse is responsible for the systematic artificial airway management to implement respiratory care,endotracheal tube care,infection prevention and control,nutritional support and health education. As a result,the incidence of fever,frequent cough,and bloody sputum was 2.12%. Pharyngeal fistula and pulmonary infection occurred in one patient,respectively. All the patients recovered well after intensive care. It is suggested that systematic artificial airway management can effectively reduce complications,improve the quality of nursing and increase patient satisfaction.

Objective To explore the pit patterns of mucosal atrophy, intestinal metaplasia, dysplasia of gastric mucosa and early gastric cancer by magnifying chromoendoscopy. Methods The pit patterns of gastric mucosa of 594 patients with gastrosia were observed with electronic magnifying endoscopy (Olympus GIF Q-240Z) assisted with methylene blue staining. Biopsies were taken from suspicious sites as observed after magnification for histopathologic examination. Results The diagnostic sensitivity, specificity and accuracy of magnifying chromoendoscopy for mucosal atrophy were 74.6%, 90.4% and 84.1%, respectively. In the central part of mild atrophic areas gastric pits were found to be decreased in quantity or even disappeared, while in severe atrophic area, scar-like changes were seen due to the disappearance of pits, with elongation and tortuosity of surrounding. Mucosa with intestinal metaplasia was lightly stained by methylene blue, and pit patterns appeared as villi, scars or coarse lines. Mucosa of dysplasia or early gastric cancer was heavily stained by methylene blue, and gastric pits were amorphous and irregular in size. Conclusion Gastric mucosal atrophy, intestinal metaplasia, dysplasia and early gastric cancer have their peculiar pit patterns, and magnifying chomoendoscopy may be useful in the diagnosis of these lesions.

Objective To evaluate the diagnostic value of Endoscopic ultrasonography(EUS) and endoscopic therapies in gastrointestinal submucosal tumors under the guidance of EUS.Methods Patients underwent endoscopy for dyspepsia at our unit. Two hundred and thirty eight patients were found to have a presumed submucosal tumor(SMT) and all subjected to Endoscopic ultrasonography(EUS). Endoscopic therapy including endoscopic mucosal resecation(EMR), endoscopic mucosa strip removal(EMSR), snare cauterization,sclerotherapy or surgery operation had been taken according to the different deriving layers of submucosal tumors. The ultimate diagnosis was confirmed by histology.Results Seventy three stromal tumors derived from muscularis mucosa,7 carcinoid in mucosa propiria; 6 cysts, 13 lipomas, 17 etopic pancreases in stomach and 5 varices in gastric fundus derived from submucosa; 95 benign stromal tumors and 21 malignent stromal tumors derived from muscularis propria,1 carcinoid invaded muscularis propria. 61 benign stromal tumors derived from muscularis mucosa , 8 benign stromal tumors derive from muscularis propria, 8 lipomas, 4 cysts, 8 etopic pancreases and 7 carcinoids were resected by endoscopy; 33 benign stromal tumors from muscularis propria, 18 malignent stromal tumors, 2 lipoma and 2 etopic pancrease,1 carcinoid were resected surgically. Submucosal tumors 97.97% diagnosed by EUS were identified by pathology.Conclusion Different layers of gastrointestinal tract with submucosal tumors can be distinguished clearly by EUS, leading to definite diagnosis of submucosal tumors. EUS is important in selecting treatment procedures of submucosal gastrointestinal tumors and should routinely be performed on all presumptive submucosal tumors prior to attempt at removal.

Objective The effectiveness on the enrichment of nuclear red blood cells(NRBC) in umbilical cord blood by polyvinylidene difluoride membrane was investigated with intervention on membrane ionic channels.Methods NRBC was isolated by the isolation solution with a density of 1.067 g/ml.The rates of the cell enrichment using verapamil and furosemide intervention by discontinuous density centrifugation were examined by flow cytometry.The NRBC that past through PVDF membrane with pore size of 5 ?m were checked and quantified by nested-PCR.Results The optimal centrifugation density was 1.067 g/ml.The mean purity of NRBC after centrifugation was 2.54%,yet the purity after intervention increased to 9.36%(3.7-fold increment).The NRBC passing through PVDF membrane was from 0.83% to 6.15%,with enrichment of 7.4 times.When NRBC was 120 cells/ml,the density of the nested PCR products increased by nearly 4 times after intervention(4.48 vs 17.78).Conclusions Verapamil and furosemide could affect the morphology of cells and promote the rate of NRBC enrichment.

Objective To study the pathogenesis and the effect of early drugs therapy of symptoms after concussion.Methods One-hundred and thirteen patients with symptoms after suffered concussion enrolled in the study and divided randomly into three groups.The patients of different groups were treated respectively with drugs,i.e.erigeron breviscapus,nimodipine,energy mixture.Symptom Check-List 90 ( SCL-90 ) and electroencephalogram(EEG) and cerebral blood flow of trancranial Doppler(TCD) were examined in the early and late stage of post-concussion.Normal population were recruited as control.All examination results and the effect of treatment were compared between treatment group and control group.Results In the scores of SCL-90,the factor scores of somatization symptom,compulsion,depressive disorder,anxiety disorders,and hostile symptom in 113 post-concussion patients in early stage were all higher than those in the normal( t =10.78,2.08,9.53,11.09 and 2.52,P ＜0.01or P ＜0.05),and as well as that of somatization symptom,depressive disorder,anxiety disorders,terror and mental disorder symptom in 12 post-concussion patients in late stage compared to normal( t =3.21,6.85,3.07,3.14 and 4.73,Ps ＜ 0.01 ).The test of EEG was abnormal in 57.4 ％ of patients in early stage and in 33.3％ in the late stage.Of all TCD results,67.0 ％ was abnormal in the early stage and 25.0％ in the late stage,The disappearance rate of post-concussion symptoms in the 14th day was significantly higher in the erigeron breviscapus group ( 45.0％ ) than in the nimodipine group ( 23.7％ ) ( x2 =3.91,P ＜0.05 ) and in the energy mixture group ( 20.0％ ) ( x2 =5.25,P ＜ 0.05 ).The disappearance rate of postconcussion symptoms in the 30th day in the energy mixture group(40.0％ ) was significantly lower than those in nimodipine group( 68.4％ )( x2 =5.94,P ＜ 0.05 ) and in erigeron breviscapus group( 75.0％ )( x2 =9.43,P ＜ 0.01 ).The occurrence rate of post-concussion sequelae was higher in the energy mixture group ( 22.9％ )than in the nimodipine group ( 5.2％ ) ( x2 =4.77,P ＜ 0.05 ) and in the erigeron breviscapus group (5.0％ )( x2 =5.15,P ＜ 0.05 ) three month after injuries.Conclusion The occurrence of symptoms originated from the organic damage of brain tissue.However,its changes were influenced by psychologic factors after concussion.Early vasodilative drugs therapy could improve the recovery of patients with post-concussion symptoms in time and decrease the occurrence of post-concussion sequelae.

Objective To compare the values of peripheral blood and tumor tissue Annexin A3 protein expressions for predictinge platinum resistance in ovarian epithelial cancer. Methods A total of 72 cases of newly treated ovarian epithelial cancer and undergoing platinum based chemotherapy after surgery,and completely followed up in this hospital from February 2010 to February 2012 were selected and divided into the platinum-sensitive group(54 cases) and platinum-resistant group(18 cases) according to the platinum resistance evaluation criteria. Peripheral blood Annexin A3 level was detected by chemiluminescence immunoassay. Tumor tissue Annexin A3 level was detected by adopting the immunohistochemical staining. The predictive value of peripheral blood and tumor tissue Annexin A3 for predicting platinum resistance was analyzed by drawing the ROC curve. Results The peripheral blood Annexin A3 level in the platinum-sensitive group was significantly lower than that in the platinum-resistant group,the difference was statistically significant(P<0.05), the positive rate of tumor tissue Annexin A3 expression in the platinum sensitivity group was significantly lower than that of platinum-resistant group(P<0.05). The median survival time in peripheral blood Annexin A3 low concentration group was significantly higher than that of high concentration group(31.2 months vs. 20.4 months, P<0.05). The median survival time in tissue Annexin A3 low expression group was significantly higher than that in the high expression group (35.2 months vs. 23.1 months P<0.05). The multivariate analysis showed that the level of Annexin A3 expression in serum and tumor tissue were the independent risk factor for affecting platinum resistance (all P<0.05). The area of curve (AUC) of peripheral blood Annexin A3 in predicting platinum resistance was 0. 821, which of tissue Annexin A3 in predicting platinum was 0. 763, peripheral blood Annexin A3 for predicting platinum resistance was significantly higher than tissue Annexin A3 (P< 0.05). Conclusion The expression levels of Annexin A3 protein in peripheral blood and tumor tissue are significantly increased in the patients with platinum resistant ovarian cancer,the predictive value of Annexin A3 protein in peripheral blood for platinum resistance is better than that of tissue Annexin A3 protein.
