ObjectiveTo discuss the clinical features, diagnosis and treatment of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome in children.Methods The clinical features and treatment process of two children with MELAS were retrospectively analyzed.ResultsThe main clinical features of MELAS were stroke-like epi-sodes, seizure, visual anomaly and lactic acidosis. Cephalic MRI ifndings performed during episode periods were in accord with the typical radiographic features of MELAS. Gene testing on the two children and their mothers showed the point mutation of A3243G in mitochondrial genome. The symptoms were improved signiifcantly after energy supply and corticosteroid treatment. Conclusions MELAS syndrome is easy to be misdiagnosed due to the varied clinical features. The diagnosis depends on the musclebiopsy and gene testing. Corticosteroid therapy is effective for MELAS syndrome.

Objective　To investigate the biological significance of p185 and p16 in breast cancer. Methods　Immunohistochemical S-P method was used to detect the expression of p185 and p16 proteins in 59 breast carcinomas，and their relations to clinicopathologic features were analyzed. Results　The positive rates of p185 and p16 were 47% and 34% respectively. No significant association was evident between the two proteins. There was also no significant relation between p16 expression and clinicopathologic features. p185 positive rate was 64% in the group of lymph-node involvement that was higher than that being 32% lymph-node negative one (P<0.05). Conclusion　p185 and p16 may play important roles independently in the development of breast cancer through different pathways. p185 detection is of important value in breast cancer.

Objective To investigate the accuracy of contrast enhanced ultrasound (CEUS) in diagnosing acute severe panereatitis.Methods Thirty three patients with acute severe pancreatitis were enrolled in the study and all of them underwent CEUS and spiral computed tomography(CT) scan.CT was taken as gold standard in acute severe pancreatitis diagnosis.CEUS were done within 72 hours after CT scan.Results Compared with CT, the sensitivity, specificity,accuracy, positive predictive value,and negative predictive value of CEUS for detecting the necrosis of pancreas were 90%, 95%, 94%, 90% and 95%respectively.The sensitivity, specificity, accuracy, positive predictive value,and negative predictive value of CEUS in diagnosing severe acute pancreatitis were 85%, 92%, 88%, 94% and 80% respectively, while 37% ,86% ,58%, 78%, 50% for conventional ultrasound respectively.Conclusions CEUS is accurate in detection of pancreatic necrosis and diagnosis of acute severe pancreatitis.

The incidence rate of erectile dysfunction (ED) is reportedly as high as 30-90% after radical prostatectomy for prostate cancer, which seriously affects the patients' quality of life. Penile rehabilitation is defined as the use of any drug or device at or after radical prostatectomy to maximize erectile function recovery. A variety of treatment options are available for post-prostatectomy ED patients, including oral phosphodiesterase 5 inhibitors (PDE5I) , intracorporal injections, vacuum erection device, and penile prosthesis. This article presents an overview of the currently used methods for the drug treatment and penile rehabilitation of the ED patients after radical prostatectomy. It seems proper to recommend daily use of a vacuum erection device plus oral PDE5I in the early postoperative period. For those who fail to respond to this therapy, intraurethral alprostadil, intracorporal injections, or a penile prosthesis could be considered.

Objective： To investigate pathophysiologic mechanism about initiation and propagation of epilepsy in a genetically epilepsy-prone rat (GEPR) model. Methods： The hippocampal MF sprouting of P77PMC rats was examined at different stages in the course of recurrent seizures using Timm method of sulfide silver staining. Results：The three groups of P77PMC rats which experienced 30 and less than 30 times of audiogenic seizure ( AGS ) and the Wistar control group did not display MF sprouting in dentate gyrus, however, the group of P77PMC rats which experienced 50 times of AGS was found hippocampal MF sprouting into the inner molecular layer of dentate gyrus. Conclusion：Our findings suggest that hippocampal MF sprouting presented not only in limbic seizure, but also in AGS, the seizure initiated in brainstem but rapidly generalized; in AGS-prone rats, recurrent AGSs can induce MF synaptic reorganization in hippocampus.

Objective To analyze pathologic features, therapeutic strategies and prognosis of patients with metastatic solid pseudopapillary tumor of the pancreas (m-SPTP). Methods Twenty five patients with m-SPTP undergoing radical resection between June 1985 and Dec 2005 were retrospectively analyzed. Kaplan-Meier analysis was used to screen out risk factors of the prognosis of m-SPTP patients.Results Twenty-three postoperative patients were followed up until Dec 2007. The follow-up rate was 92% and the median follow up time was 78 months. The 5-year overall survival rate was 82%. Kaplan-Meier analysis showed that five variables including age, tumor size, pathologic features, number of metastatic lesions and lymphatic metastasis were related to overall survival. Conclusions Solid pseudopapillary tumor of the pancreas is low-grade malignant potential with a favorable prognosis, but not for the m-SPTP.Patients of ≥40 years old, tumor size (≥6 cm), pathologic features (including presence of areas with diffuse growth pattern and tumor necrosis), multiple metastatic lesions and lymphatic metastasis have poor prognosis.
