Objective To explore the protective effect of a small balloon on bifurcation lesions by applying a single stent treatment of coronary bifurcation lesions strategy. Methods Fifty patients with coronary bifurcation lesions were randomly divided into A group and B group( 25 cases for each group ). Patients in A group were treated with the pre-entry protection branch guide wire to complete the main branch balloon pre-dilation,stenting,while in B group were treated with the set aside the branches of a small balloon. The information of main branch balloon pre-dilation,stenting were recorded. The blood flow slowed down,the incidence of side branch occlusion or stent placement,and the incidence of postoperative 24 h troponin I( cTnI) levels were measured. Results Nine cases(36%)in A group occurred lower branch blood flow,which due to 4 cases(16% )with significantly narrow branch stenting,2 cases(8%)with complete occlusion. There were only 2 cases(8%)with decrease branching blood flow in B group,and the difference was significant(P=0. 041, 0. 022). The cases with higher cTnI after 24 h in A group were 11( 39%),significantly higher in group B (3(12 %);P =0. 027 ). Conclusion Compared with the traditional protection guidewire,the approach of setting aside a small balloon to protect important branch can effectively prevent important branch occlusion, branch involvement due to lower incidence of myocardial infarction.

Objective To summarise the experience of surgical treatment of invasive pulmonary fungal infection in patients with hematologic malignancies.Methods From Jan.2000 to Dec.2012,78 hematologic patients with invasive pulmonary fungal infections,including 49 males and 29 females with average age of 29.6 years,underwent surgical treatment.Preoperatively,all patients with 1 to 3 courses of chemotherapy had received average 4 weeks antifungal treatment.There were 58 cases received conventional open thoracic surgery and 20 cases received VATS including lobectomy,segmentectomy,wedgectomy.Results The procedures were successful,the average operation time w as(125.3 ± 35.7) min and intraoperative blood loss was(253.1 ± 42.8) nl.There were no severe postoperative complications.The main complications were excessive effusion (10.2％) and persistence airleak (7.7％).The hospital days was(7.8 ± 2.5) days,no reoperation and death case in 30 days after operation.The follow-up was from 6 to 24 months,38 cases(48.7％) received prophylaetic antifungal treatment,no ease with fungi spread and recurrence.Conclusion The surgical treatment is safe and useful for the hematologic patients with invasive pulmonary fungal infections,when internal medicine conservative treatment is invalid.

Objective To assess the feasibility of nuclear matrix protein 22(NMP22)and urinary bladder cancer,antigen (UBC) for the early diagnosis of bladder transitional cell carcinoma and its influencing factors.Methotis 105 subjects,including 60 patients of bladder cancer,25 patients of urological benign disease and 20 normal (healthy)individuals were enrolled in this study.Urine NMP22 and UBC wag assessed by enzyme-linked immunosorbent assay(ELISA).Urine NMP22 and UBC as well as exfoliocytology were conducted for the purpose to compare the sensitivity,specificity,positive and negative predictive value of these three ways.Results The sensitivity of NMP22(88.3%)and UBC(86.7%)were significantly better than exfolioeytology(40.0%,P<0.01).The specificity of NMP22,UBC and exfoliocytology were 80.0%,84.0%and 92.0%,respectively, the positive predictive values were 91.4%,92.9%and 92.3%,and the negative predictive values were 74.1%.72.4%and 38.9%.Conclusions NMP22 and UBC are sensitive,specific,simple,feasible and noninvasive diagnostic markers for the early detection of urinary bladder transitional cell cancer.

Objective To investigate the surgery method for early spontaneous posterior interosseous nerve entrapment,to observe the postoperative efficacy in treatment,to evaluate the surgical outcomes,and to provide a foundation for clinical choice of reasonable operation scheme.Methods 21 cases of early spontaneous posterior interosseous nerve entrapment received operation. 1 3 cases (1 8 arms) were treated by neurolysis, and 8 cases (8 arms )were treated by nerve grafts with small vessels wrapping operation;all the patients were followed up for 10 to 20 months;the finger extensor muscle strength and metacarpophalangeal joint activity were evaluated. Results The lesion extensor muscles were part of the denervation changes.Neurolysis muscle strength:14 arms were excellent(82.35%),2 arms were good,1 arm was fair,1 case was lost;extensor function:15 arms were excellent(88.24%),1 arm was good,1 arm was fair,1 case was lost.Nerve graft muscle strength:6 arms were excellent(75.00%),1 arm was good,1 arm was fair;extensor function:7 arms were excellent(87.50%),0 arm was good,1 arm was fair.Conclusion Neurolysis can have a good efficacy in treatment of early spontaneous posterior interosseous nerve entrapment without obvious degeneration.When the severe degeneration of entrapment nerve happens,a nerve graft surgical treatment is needed.

Objective To investigate how many probably benign lesions on ultrasound(US) fulfilled the published criteria and to evaluate how clinical and personal factors influenced the categorization of breast lesions.Methods A total of 487 lesions in 487 women with more than 12 months follow-up after the initial category 3 assessment on US were included.The initial US images were retrospectively reviewed according to previously published criteria,and evaluated several factors that could influence the characterization of breast lesions in clinical practice such as age,multiplicity,palpability,radiologist 's experience,and lesion size.Results Of 487 lesions,479 (98.36%) were benign and 8 (1.64%) were malignant.Of 487 lesions,203(41.68%) including 8 malignancies were reassessed as category 4.If strict criteria had been applied at initial US examination,the positive biopsy rate would have been only 3.94% (8/203) and 96.06% (195 of 203) biopsies would have been unnecessary.Lesions in women 40 years or older and multiple lesions were more frequently reassessed as category 4 (P = 0.008 and P = 0.006,respectively).The presence of palpability,lesion size,and the radiologist 's experience did not significantly influence the categorization of breast lesions on US.Of 487 probably benign lesions,41.68 % could be classified as category 4 lesions when strict criteria were applied in initial practice.Conclusions The multiplicity of the lesion and the patient 's age were found to have a significant influence on the classifcation of probably benign solid masses.
