Gastric bronchogenic cysts (GBCs) is uncommon with atypical clinical features. It is difficult to diagnose by preoperative imaging examinations. Therefore , postoperative histopatho-logical examination is regarded as the golden bacteria in ultimate diagnosis. The treatment of GBCs:ultrasound-guided fine needle aspiration and endoscopic mucosal resection is only used for small GBCs with intra-cavity growth pattern. However , GBCs with extra-cavity growth pattern is featured with deeply anatomical position , large size , and prone on attaching to vital blood vessels and organs , which makes laparoscopic resection is the first choice in treatment. The authors introduce the diagnosis and treatment of a case of GBCs attaching to lesser curvature , in order to provide references for clinical diagnosis of GBCs.

Background and purpose:The most clearly recognized benefit of neoadjuvant chemotherapy (NAC) is that it can increase the proportion of patients who can be treated with breast-conserving therapy (BCT). However, the shrinkage modes of the primary breast tumor after NAC have been conifrmed as a predictor of BCT rate and prognosis. This study is to evaluate the accuracy of MRI predicting the shrinkage mode of the primary breast tumor after NAC with three-dimensional reconstruction technique.Methods:Sixty-one women with pathologically proven solitary invasive ductal carcinoma (ⅡA-ⅢC) were recruited. Breast specimens were prepared with PMSS, and residual tumors were microscopically outlined, scanned and registered by PHOTOSHOP software. The 3D model of residual tumors was reconstructed with 3D-DOCTOR software based on pathology and MRI imaging characteristics to evaluate the shrinkage mode. We devided the pathological shrinkage modes into surgical pCR (no residual tumors), solitary lesions without surrounding lesions, multinodular lesions, solitary lesions with adjacent spotty lesions and diffuse lesions. Further, the clinical-pathological shrinkage modes were divided into 2 categories: distinct shrinkage mode (DSM, the longest diameter of the pathological residual tumors was less than 50% and ≤2 cm in comparison with the primary tumor before NAC) and non-distinct shrinkage mode (NDSM, the longest diameter of the pathological residual tumors was more than 50% and/or >2 cm in comparison with the primary tumor before NAC).Results:The surgical pCR, solitary lesions without surrounding lesions, multinodular lesions, solitary lesions with adjacent spotty lesions and diffuse lesions were observed in 23, 17, 5, 9, 7 and 18, 3, 13, 20, 7 patients by MRI and pathology, respectively (P=0.001). The accuracy, sensitivity and speciifcity of MRI for predicting pathological shrinkage modes were 86.2%, 65.6% and 91.4%, respectively. The DSM was observed in 36 (59.0%) patients by pathology, and 38 (62.3%) patients by MRI. Two methods had a high consistency in clinical-pathological shrinkage modes (κ=0.863,P=0.000). The accuracy, sensitivity and speciifcity of MRI for predicting clinical-pathological shrinkage modes were 91.0%, 64.0% and 94.8%, respectively. There was not a statistic difference in prediction between DSM and NDSM by MRI (P>0.05). Receiver operating characteristic (ROC) curve analysis showed an AUC of 0.928 (P=0.000) for MRI to predict the clinical-pathological shrinkage mode.Conclusion:Three-dimensional MRI reconstruction after NAC could simulate and predict spatial location of residual tumors, and can be helpful in selecting patients who received BCT after NAC with tumor downstaging.

Objective To observe the pathological infrastructure changes of lung tissue in diabetic rat with pulmonary fibrosis and the preventive effect of rosiglitazone intervention. Methods The experimental type 2 diabetic rats were yielded by high-sugar, high fat diet plus intraperitoneal injecting streptozotocin (STZ). The pathological infrastructure changes of lung tissue were observed by transmission electron microscopy in the control, diabetes mellitus group and rosiglitazone treatment group respectively, and the hydroxyproline contentswere determined simultaneously. Results We observed accumulation of collagen fibers and extracellular matrix in the lung tissue of simple diabetic rat, which indicated pulmonary fibrosis. The hydroxyproline contents were significantly higher in diatetes mellitus group when compared to the control at 12 weeks[ 0. 77 ± 0. 03μg/(mg·prot) vs.0.63 ±0.03 μg/(mg·prot)] and 20 weeks [0.93 ±0. 10 μg/(mg·prot) vs.0.87 ±0.10μg/ (mg·prot) ]. (Ps < 0.05) , but the rosiglitazone intervention significantly reduced the hydroxyproline 3contents in diabetes mellitus rats [0.85 ±0.08 μg/(mg·prot) vs.0.87 ±0. 10 μg/(mg·prot) ,P<0.05].Conclusion Pulmonary fibrosis occurred in diabetic rats lung tissue,while rosiglitazone can alleviate it.
