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.

Objective To investigate the clinical effect of the treatment of erosive oral lichen planus and recurrent aphthous ulcer by using Pudilan Xiaoyan Koufuye.Methods The clinical data of 138 cases of oral mucosal diseases were retrospectively analyzed from September 2015 to June 2016 in our hospital, eOLP patients 50 cases, 11 cases in the control group one and the control group two, 28 cases in the observation group; ROU patients 88 cases, 21 cases in the control group one and the control group two, 46 cases in the observation group.The control group one was treated with topical western medicine, while the control group two was treated with Pudilan Xiaoyan Koufuye,and the observation group was treated with local topical spray and Pudilan Xiaoyan Koufuye, compared the total effective rate, VAS score and mucosal congestion in different groups of patients with oral diseases, and to observe the adverse reactions of the patients during the treatment.Results After one week of treatment, the total effective rate of treatment was significantly different between eOLP patients and ROU patients (P<0.05),the total effective rate of the observation group was higher than that of the control group one and the control group two ( P <0.05 ) .After two weeks of treatment, the total effective rate of eOLP patients was significantly different, and the total effective rate of observation group was higher than that of control group one (P<0.05),there was no significant difference among the ROU patients.The degree of mucosal hyperemia and the VAS score in the observation group were significantly different from those in the control group one and control group two in the patients with eOLP and ROU ( P <0.05 ) .No significant adverse mucosal staining occurred in all groups of patients, and there was no discontinuation due to obvious adverse reactions.Conclusion Pudilan Xiaoyan Koufuye adjuvant treatment of eOLP and ROU patients with short-term effect is significant, can improve the total effective rate of treatment, and no serious adverse reactions, high safety.

[Objective]To observe the clinical effect of the treatment of hyperplastic nonunion of the tibia with interlocking intramedullary nailing,fascia pedicled callus flap and bone grafting.[Method]Twelve cases of nonunion of the tibia were treated with intramedullary interlocking nailing,fascia pedicled callus flap and bone grafting,and there were 8 males and 4 females.The patients age ranged from 26 to 64 years,with an average of 45 years.[Result]All cases were followed-up for an average of 48 months and achieved a solid union within 4～6 months.[Conclusion]Intramedullary interlocking nailing,fascia pedicled callus flap and bone grafting have the design of the reasonable biomechanics,the function of untispinning and unticurtailing,less partial blood decompose.The fascia pedicled callus flap and iliac bone grafting could result in solid union and it is a recomment method for promoting bone-healing up after grafting and forming.

Objective:To study the effect of overdose fluoride on Smad3 expression during development course of Wistar rat's incisor,and then to explore pathogenesis of dental fluorosis.Methods:20 Wistar rats(10 male rats and 10 female rats)were randomly divided into two groups.Experiment group was feed with water contained 0.1 g/L fluorin and normal group with distilled water was served as control.After 8 weeks all rats were sacrificed.Immunohistochemistry was used to observe the effect of overdose fluorin on Smad3 expression in rat's ameloblast and odontoblast.Results:The immunohistochemistry results demonstrated that in experiment group,Smad3 expression in rat's ameloblast and odontoblast was lower than those in control group,and statistic analysis showed there were significant differences between the two groups(P

Objective To summarize our experience of the diagnosis and treatment in patients with abdominal aortic aneurysm(AAA).[WT5”HZ]Methods [WT5”BZ]From 1980 to 1999 sixty five AAA patients were hospitalized with 40 cases of general type, 18 cases of rupture type,4 cases of inflammatory type and 3 cases of infective type. In situ artificial graft transplantation was performed in 62 cases and nonanatomy pathway in 2 cases. The remaining one with inflammatory type was treated by interventionel therapy.[WT5”HZ]Results [WT5”BZ]57 cases were cured and were followed up from 1 to 12 years without complications.Death occurred in 7 cases.[WT5”HZ]Conclusions [WT5”BZ]The abdominal pulsate mass should draw much attention. Ultrasound is the selected examination and DSA, helix CT are accurate image appliance. It can elevate the curative ratio and decrease the mortality through rational operation based on the location, type and individual condition of AAA patients.

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.
