Objective To investigate the clinical significance of PET-CT to diagnose breast cancer and the axiUary lymph nodes metastasis. Methods 40 patients with breast cancer performed PET-CT were enrolled in the research. Qualitation the primary tumor and accuracy of PET-CT were evaluated on pathological results and compared with axillary lymph nodes dissection. To analyzed the concordance of the size of primary tumor on pathological result with B-mode ultrasonic and PET-CT and the correlation with the SUV. Results The accuracy, sensitivity and specificity of PET-CT in identifying breast cancer were 95%, 94%, 100%. The accuracy, sensitivity and specificity of PET-CT based on the situation of the axillary lymph node dissection were 88.2% 89.2% 83.3%. A significant association was found between tumor weiweihong and PET-CT, furthermore it had not association with SUV. Conclusion The diagnosis of PET-CT in identifying breast cancer and the axillary lymph node metastasis basically conforms to pathology. It possesses high sensitivity and specificity especially in identifying the size of the primary lesion. It offers a beneficial method to determine the axillary lymph node dissection and reasonable therapeutic regimen.

Objective To report a case presented with atypical clinical and radiological appearance in the early stage and finally pathologically confirmed as chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids ( CLIPPERS) , aiming to improve the understanding of the disorder. Methods The clinical, imaging, laboratory and pathological features as well as treatment and prognosis of a pathologically confirmed CLIPPERS patient with repeated relapsing-remitting course and stepwise progression in nine years were retrospectively analyzed. Results There were five relapsing-remitting processes in total clinical course of nine years. The clinical and radiological appearance was atypical in the early stage. At the first attack, the patient presented with fever, headache, altered consciousness and epileptic seizure. In the following courses, the patient presented with ataxia, blurred vision and limb weakness. Brain MRI (2006-2009) showed multiple abnormal signals including supratentorial white matter, pons and cerebellum with patchy gadolinium enhancement. Treatment with steroids resulted in a favorable clinical and radiological improvement. The symptoms of this attack included limb weakness, blurred vision, dysdipsia and dysarthria. Physical examination showed cognitive dysfunction, multiple cranial nerves injuries and bilateral pyramidal signs. Brain MRI showed multiple abnormal signals involved pons and cerebellum predominantly as well as supratentorial white matter with punctate gadolinium enhancement peppering the pons and cerebellum. A characteristic predominantly T lymphocytic perivascular infiltration was seen on brain biopsy. Both the imaging and histological findings were consistent with the CLIPPERS features. High-dose steroids treatment was given and obvious clinical and radiological improvements were observed. After discharge, steroids were reduced slowly combined with the use of immunosuppressant to avoid relapse of the disorder. Conclusions There is heterogeneity in clinical manifestations of CLIPPERS with repeated relapsing-remitting course and imaging presentations are sometimes atypical in the early stage, which leads to the misdiagonsis and missed diagnosis. Distinctive pathology is the “gold standard” for definite diagnosis. The nosological position of CLIPPERS is still unclear. Repeated relapse-remitting leads to secondary cerebral atrophy and degeneration, with the risk of progressing to primary central nervous system lymphoma. Early and vigorous steroids treatment with continuing maintenance immunotherapy results in the decreased relapse and best long-term prognosis. The neurologist should strengthen the understanding of CLIPPERS for early correct diagnosis and treatment aiming to reduce the functional disability.

Objective To study the feature of clinical and pathological type of Henoch-Sch(o)nlein purpura nephritis (HSPN) in children.Methods Clinical and pathological data of HSPN in 279 children were collected and retrospectively analyzed.Results Clinical manifestation of HSPN in 279 children with haematuria and proteinuria (107 cases,38.4%) was the most common type,followed by nephritic syndrome type (69 cases,24.7%),isolated proteinuria type (40 cases,14.3%),isolated hematuria type (29 cases,10.4 %),acute glomerulonephritis type (21 cases,9.3 %),rapidly progressive glomerulonephritis type (8 cases,2.9%),chronic glomerulonephritis type (5 cases,1.8%).According to the International Study of Kidney Disease in Children,the majority renal pathological type of HSPN were grade Ⅱ (133 cases,47.7%)and grade Ⅲ (109 cases,39.1%).The pathological changes of hematuria and proteinuria type were mainly grade Ⅱ (61 cases,57.0%) and grade Ⅲ (35 cases,32.7%),and the pathological change of nephritic syndrome type was grade Ⅲ (41 cases,59.4%).All of renal pathological changes,38.7% (108/279) had codeposition of immunoglobulins A and M,30.8% (86/279) had co-deposition of immunoglobulins A,G and M.The pathological change of nephritic syndrome type was more serious (x2 =35.989,P < 0.05).Immune complex deposition was not correlated with renal pathologic classification (P > 0.05).Conclusion The HSPN patients mainly show the type of hematuria and proteinuria and the type of nephritic syndrome.The majority renal pathological type of HSPN are grade Ⅱ and grade Ⅲ.In children with HSPN,the severity of the clinic symptoms is not completely consistent with the pathological changes.The pathological changes of nephritic syndrome type are more serious.To improve theprognosis of HSPN,we should make the treatment planning according to the clinical types and pathologic classification.

BACKGROUND:Currently, human umbilical cord derived-mesenchymal stem cel s are mainly for local transplantation, which has some shortcomings, such as large trauma, bleeding, complications, that limit its widespread application in clinical practice. OBJECTIVE:To investigate the feasibility of intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s for repair of spinal cord injury. METHODS:Eighty Wistar rats with spinal cord hitting were divided into five groups:blank control group with no transplantation (n=10), DMEM local transplantation group (n=15), DMEM intravenous transplantation group (n=15), cel local transplantation group (n=20), cel intravenous transplantation group (n=20). The functional recovery of spinal cord injury was observed with Basso, Beattie and Bresnahan scores at regular time as wel as hematoxylin-eosin staining and immunohistochemistry staining. RESULTS AND CONCLUSION:During 1 day to 2 weeks after transplantation, there was no significant difference in the Basso, Beattie and Bresnahan scores between the five groups;within 4-12 weeks after transplantation, the Basso, Beattie and Bresnahan scores were significantly higher in the two cel transplantation groups than the other three groups, but there was no difference between these two cel transplantation groups (P>0.05). Histological observation showed that the number of voids and glial scars was less in the cel local transplantation group and cel intravenous transplantation group compared with the other three groups, and there was also no difference between the two cel transplantation groups. These results indicate that the intravenous transplantation of human umbilical cord derived-mesenchymal stem cel s is similar to the local transplantation in the repair of acute spinal cord injury, which is simple and avoids secondary injuries and various complications. It is recommended that this method provide a new approach for cel transplantation.
