Percutaneous coronary intervention(PCI) has been a mainstay in the management of coronary artery disease since its introduction in the late 1970s.Bare-metal stents and,more recently,first-generation drug-eluting stents(DES),such as sirolimus-eluting(Cypher) and paclitaxel-eluting stents(Taxus),have further improved results of percutaneous coronary intervention by improving early results and reducing the risk of restenosis.There are currently debates on the safety of these first-generation DES,given the potential for late stent thrombosis which is a first-generation drug-eluting stent of the largest security issue,especially after discontinuation of dual antiplatelet therapy.Next-generation DES such as everolimus-eluting stents(Xience V) holds the promise of superior anti-restenosis efficacy as well as long-term safety.This review makes a presentation of the evidence-based clinical research according to everolimus-eluting stents(Xience Ⅴ).

OBJECTIVE: To study the effects of Naomaitong Recipe, a compound Chinese herbal medicine, on the expressions of nuclear factor-kappaB (NF-kappaB) and nitric-oxide synthases (NOSs) in brain tissue after focal cerebral ischemia reperfusion in aged rats and the dosage-effect relationship. METHODS: We adopted the middle cerebral artery occlusion (MCAO) in aged rats as the focal cerebral ischemia model, with 3-hour ischemia and 12-day reperfusion, and observed the changes of the nerve dysfunction score, the water content of cerebral constitution and the expressions of NF-kappaB, heat-shock protein 70 (HSP70) and NOSs in cerebral cortex. RESULTS: The nerve dysfunction score, the water content of cerebral constitution, the expressions of NF-kappaB, HSP70, neuronal nitric-oxide synthase (nNOS), endothelial nitric-oxide synthase (eNOS) and inducible nitric-oxide synthase (iNOS) in the untreated group were higher than those of the sham-operated group. The nerve dysfunction score, the water content of cerebral constitution, the expressions of NF-kappaB, iNOS and nNOS were lower, while the expressions of HSP70 and eNOS were higher in the high-, medium- and low-dose Naomaitong-treated groups and nimodipine-treated group than those of the untreated-group. The nerve dysfunction score and the expression of nNOS were lower, while the expression of eNOS was higher in the medium-dose Naomaitong-treated group than those of the nimodipine-treated group. The expressions of HSP70 and eNOS were higher, while the other indices were lower in the medium-dose Naomaitong-treated group than those of the low-dose Naomaitong-treated group. CONCLUSION: Naomaitong Recipe can protect the brain cells from damage after focal cerebral ischemia reperfusion injury by adjusting the expressions of NF-kappaB, HSP70 and NOSs, and the medium-dose Naomaitong Recipe is more effective.

Background:Esophageal cancer is a commonly seen gastrointestinal malignancy. Early detection of superficial neoplastic lesions is critical for improving the prognosis. Therefore,it is of great importance to explore new endoscopic techniques for increasing the detection rate of early esophageal cancer. Aims:To assess the diagnostic accuracy of targeted biopsy guided by magnifying endoscopy combined with narrow-band imaging(ME-NBI)for suspected superficial lesions in esophagus. Methods:In a prospective cross-over designed trial,65 patients with suspected superficial lesions in esophagus detected by conventional gastroscopy were randomly assigned to group A and group B. Patients in group A received primary white light imaging(WLI)with Lugol’s staining followed by ME-NBI 4-6 weeks later,and patients in group B received primary ME-NBI followed by WLI with Lugol’s staining 4-6 weeks later. Random biopsy was performed in WLI with Lugol’s staining,while targeted biopsy was performed in ME-NBI based on Inoue’s intraepithelial papillary capillary loop (IPCL)classification. Results:A total of 58 patients completed the study and 68 lesions were eligible for statistical analysis. More biopsies were taken in WLI with Lugol’s staining than in ME-NBI(3. 7 vs. 2. 2 per lesion,P < 0. 05). The overall agreement of IPCL classification with definite pathological diagnosis was 89. 7% . The overall agreement of targeted biopsy by ME-NBI and random biopsy by WLI with Lugol’s staining was 85. 3% ;the specificity and positive predictive value of both ME-NBI and WLI with Lugol’s staining for neoplastic lesions were 100% ,but the sensitivity of ME-NBI was superior to that of WLI with Lugol’s staining(90. 0% vs. 70. 0% ,P < 0. 05). The agreement of ME-NBI-guided targeted biopsy with definite pathological diagnosis was slightly higher than that of random biopsy by WLI with Lugol’s staining(89. 7% vs. 86. 8% ,P > 0. 05). Conclusions:ME-NBI-guided targeted biopsy is superior to random biopsy by WLI with Lugol’s staining for detection of superficial neoplastic lesions in esophagus with higher sensitivity and less number of biopsy. It might benefit the follow-up endoscopic treatment.

ObjectiveTo investigate the clinical outcome of laparoscopic nephroureterectomy (LUNT) for native upper tract urothelial carcinoma (UC) in renal transplant (RT) recipients.Methods We conducted a retrospective analysis on 1130 RT recipients,and 9 patients (0.8%,9/1130) with native upper tract UC were identified. UC was confirmed pathologically in the 9 patients,including 3 cases of unilateral ureter tumor (2 on the right,and 1 on the left),4 cases of unilateral renal pelvis tumor (2 on the right,2 on the left),1 case of bilateral ureter tumor and 1 case of tumor in the right ureter and left kidney.Females predominated (8/9) in the 9 patients with upper tract UC.The patients with left upper urinary tract cancer underwent LUNT using a retroperitoneal approach with a technique of transurethral circumcision of the ureteral orifice.The patients with right upper urinary tract cancer were subjected to nephroureterctomy with ureterectomy and bladder cuff excision by complete laparascopy through a transperitoneal approach. Immunosuppressive protocol conversion from calcineurin inhibitors to sirolimus was performed on all cases. Results In the 9 patients,11 LUNTs were performed successfully without conversion to open surgery.The follow-up period was from 6 to 48 months. One patient died of lung metastasis at 8th month after tumor excision,and 1 patient displayed ductal cancer of the left breast at 7th month after LNUT.Another seven patients showed no evidence of disease during the follow-up period with normal renal function.ConclusionOur present clinical experience suggested that LNUT for the native upper tract cancer in renal transplant recipients is feasible,safe,and effective.
