We treated five patients with the over-the-scope Padlock Clip?. It is a nitinol ring, with six inner needles preassembled on an applicator cap, thumb press displaced by the Lock-It? delivery system. The trigger wire is located alongside the shaft of the endoscope, and does not require the working channel. Three patients had recurrent bleeding lesions(bleeding rectal ulcer, post polypectomy delayed bleeding and duodenal Dieulafoy's lesion) and two patients had a persistent respiratory-esophageal fistula. In all patients a previous endoscopic attempt with standard techniques had been useless. All procedures were conducted under conscious sedation but for one patient that required general anaesthesia due to multiple comorbidities. We used one Padlock Clip? for each patient in a single session. Simple suction was enough in all of our patients to obtain tissue adhesion to the instrument tip. A remarkably short application time was recorded for all cases(mean duration of the procedure: 8 min). We obtained technical and immediate clinical success for every patient. No major immediate, early or late(within 24 h, 7 d or 4 wk) adverse events were observed, over follow-up durations lasting a mean of 109.4 d. One patient, treated for duodenal bulb bleeding from a Dieulafoy's lesion, developed signs of mild pancreatitis 24 h after the procedure. The new over-the-scope Padlock Clip? seems to be simple to use and effective in different clinical settings, particularly in "difficult" scenarios, like recurrent bleeding and respiratory-oesophageal fistulas. 展开更多

Upper gastrointestinal bleeding is defined as the bleeding originating from the esophagus to the ligament of Treitz and further classified into variceal and nonvariceal gastrointestinal bleeding.Non-variceal upper gastrointestinal bleeding remains a common clinical problem globally.It is associated with high mortality,morbidity,and cost of the health care system.Despite the continuous improvement of therapeutic endoscopy,the 30-d readmission rate secondary to rebleeding and associated mortality is an ongoing issue.Available Food and Drug Administration approved traditional or conventional therapeutic endoscopic modalities includes epinephrine injection,argon plasma coagulation,heater probe,and placement of through the scope clip,which can be used alone or in combination to decrease the risk of rebleeding.Recently,more attention has been paid to the novel advanced endoscopic devices for primary treatment of the bleeding lesion and as a secondary measure when conventional therapies fail to achieve hemostasis.This review highlights emerging endoscopic modalities used in the management of non-variceal upper gastrointestinal related bleeding such as over-the-scope clip,Coagrasper,hemostatic sprays,radiofrequency ablation,cryotherapy,endoscopic suturing devices,and endoscopic ultrasound-guided angiotherapy.In this review article,we will also discuss the technical aspects of the common procedures,outcomes in terms of safety and efficacy,and their advantages and limitations in the setting of non-variceal upper gastrointestinal bleeding. 展开更多

Objective: In an era of ever evolving, promising new therapies for advanced non small cell lung cancer (NSCLC), early predictors of response to therapy, are needed. We evaluated early variations in CYFRA 21-1 serum levels of patients with advanced NSCLC receiving first line chemotherapy and correlated the results with objective tumor response. Methods: 29 consecutive, previously untreated, patients of advanced non small cell lung cancer, with measurable disease on CT scan were evaluated. All patients were treated with conventional systemic chemotherapy, although the choice of chemotherapy was left to the discretion of the treating physicians. Serum samples were obtained immediately before the start of 1st and 2nd cycles of chemotherapy. CYFRA 21-1 was measured with an electrochemiluminescense immunoassay on an automatic analyzer (Elecsys 2000; Roche Diagnostics). Response was evaluated using Response evaluation criteria in solid tumors (RECIST) criteria. Results: 10 patients had partial response, 9 patients had stable disease and 9 had progressive disease. None of the patients had complete response. 21/29 (72%) patients had an elevated baseline value of CYFRA 21-1.62% patients (18/29) had a decrease in CYFRA 21-1 after 1 cycle of chemotherapy. The average reduction in the 2nd reading was irrespective of whether baseline value was normal or not. The average reduction was statistically significant (P = 0.002; 95% CI, from 0.8369 to 3.49464; t test). 8 out of 10 (80%) patients with partial response had a reduction in their 2nd reading of. CYFRA (P = 0.019; 95% CI, from 0.81965 to 7.20035; t test) which was significant. We also observed that 6/9 (66%) patients whose disease remains stable also had a decrease in their subsequent reading (P = 0.0106; 95% CI, from -0.44942 to 3.82720; t test), though it was not significant statistically. Although 5 out of 9 (55%) patients, who had an increase in their CYFRA 21-1 level, had progressive disease, but it was not statistically significant (P = 0.537; 95% CI, from -1.20021 to 2.13354; ttest). 14 out of 19 (73%) who either had partial response or had stable disease, had a reduction in their 2nd value of CYFRA 21-1 and was significant statistically (P = 0.004; 95% CI, from 0.74792 to 3.50208; t test). We also observed that except for 1 patient, all patients who had a decrease of 42% or more in their subsequent CYFRA 21-1 level, were those who had either responded to chemotherapy or had stable disease (P = 0.001), which was statistically significant. Conclusion: We can conclude that monitoring of serum marker CYFRA 21-1, early dudng first-line chemotherapy may be a useful prognostic tool for evaluation of early tumor response in patients with advanced NSCLC. 展开更多

Increasing evidence indicates that aberrant expressions of some microRNAs are associated with cancer progression.However,the roles and biological mechanisms of miRNA-16-5p in human non-small cell lung cancer(NSCLC)are not to be well studied.Here,we validated that the expression of miR-16-5p was decreased significantly in NSCLC samples and cell lines.The correlation between the clinicopathological features of NSCLC and the miR-16-5p expression showed that the expression of miR-16-5p in non-small cell lung cancer was linked with the advanced TNM stage,positive lymph node metastasis,with short overall survival(OS).Also,a negative correlation between miR-16-5p and Fermitin family member 2(FERMT2)was observed,implying there may be a potential link about their regulation.The hypothesis was further confirmed by in-silico analysis and dual-luciferase reporter assay.Moreover,we demonstrated that the transfections of miR-16-5p mimics could alter some biological characteristics of NSCLC cells remarkably accomplished by the expression variance of FERMT2 in vitro and in vivo assays.Summarily,this study demonstrated that miR-16-5p,as a tumor suppression factor in NSCLC by targeting FERMT2,could serve as one promising biomarker in the prediction for NSCLC patients. 展开更多

In my ten-yeat experience of tenching English as major in college , I feel that students experience more difficulties in listening lessons than in other lessons. What, then, prevents students from achieving success in the listening class? I suggest that anxiety is one of the major factors, which interferes with students listening comprehension. And I would agree with writers such as Gardner and Horwitz et al. (1991)that anxiety may impede learner’s ability to perform successfully in all aspects of learning a foreign language.
