Objective To study the clinical pathological features of mesenteric and omental inflammatory myofibroblastic tumor (IMT) in children.Method Clinical features,laboratory result,pathological evidence for diagnosis and treatment of 5 cases with mesenteric and omental IMT were analyzed and evaluated.Results Intra-abdominal mass was most frequently found in childhood mesenteric and omental IMT.Gastrointestinal obstruction was showed in 2 cases.Anemia,leucocytosis,thrombocytosis,polyclonal-hyperglobulinemia appeared in 5 cases.The histological pattern showed:4 cases were myxoid pattern IMT,1 case was compact spindle cells pattern IMT.Immunohistochemistry showed:the spindle cells were expressed vimentin,smooth muscle action(SMA) and desmin.Partial spindle cells were anaplastic lymphoma kinase(ALK) and cytokeratin(CK) positive,while S-100 protein,CD34 were negative.Complete surgical excision was performed on 5 cases.Follow-up studies ranged from 5 months to 3 years,and no patient developed recurrence.Conclusions Childhood mesenteric and omental IMT is a rare interstitial tumor.The diagnosis should be based on pathological and immunohistochemistry examinations.Most cases are benign,and complete surgical excision can avoid local recurrence.

Objective To investigate the expression and significance of Smad 7,Smurf 1 and Smurf 2 in basal cell carcinoma and squamous cell carcinoma.Methods Biopsy specimens were resected from 14 patients with basal cell carcinoma,19 patients with squamous cell carcinoma and 30 normal controls.Quanti- tative real-time PCR and immunohistochemical techniques were utilized to assess the expression of Smad 7, Smurf 1 and Smurf 2 in these specimens.Results The gray scale for staining of Smad 7,Smurf 1 and Smurf 2 was 166.61?7.11,166.08?8.71,and 166.25?8.15 respectively in basal cell carcinoma,161.66?5.52,166.84?9.27,and 169.98?9.48 respectively in squamous cell carcinoma.The expression levels of Smad 7,Smurf 1 and Smurf 2 were all significantly increased in basal cell carcinoma and squamous cell car- cinoma in comparison with normal controls.Conclusions The over-expression of Smad 7,Smurf 1 and Smurf 2 may interfere with transforming growth factor?signaling transduction pathway through several links,therefore prevent the inhibitory effect of transforming growth factor?on epidermal proliferation,and accelerate the abnormal proliferation in above epidermal tumors.

Objective To investigate the expression and significance of transforming growth factor beta receptors (TGF?RⅠ, TGF?RⅡ) in basal cell carcinoma and squamous cell carcinoma. Methods The expression of TGF?RⅠand TGF?RⅡwere assessed by quantitative real-time PCR and streptavidin -peroxidase (SP) immunohistochemical techniques in specimens of basal cell carcinoma, squamous cell carcinoma and normal control skin. Results Eighteen patients with basal cell carcinoma and twenty-four with squamous cell carcinoma were enrolled in the study. The expression levels of TGF?RⅠand RⅡmRNA were significantly down-regulated in basal cell carcinoma and squamous cell carcinoma in comparison with those in control skin specimens (P

Objective:To summarize our experience in perioperative anesthetic management for fulminant hepatic failure (FHF)patients receiving liver transplantation.Methods:The clinical anesthetic data of 48 FHF patients receiving orthotopic liver transplantations(OLT)from January 2006 to January 2007 were retrospectively analyzed,and the anesthetic management expe- rience was summarized.General anesthesia was applied;the hemodynamics was monitored during the operation and doses of adrenaline and phenylephrine were adjusted according to the monitoring results.Blood samples were obtained before operation, before anheptic,30 min after anhepatic phase,5 min before neohepatic phase,and 5 min,30 min and 60 min after neohepatic phase for blood gas and electrolyte analysis and for determination of coagulation function;the drugs were subsequently adjusted according to analysis results.Results:All the 48 patient underwent successful anesthetic management and there was no death dur- ing opearation.The average blood loss during operation was(5 219?478)ml.Mild alkalosis,hypokalemia,hyponatrium,and hy- pocalcemia were present before operations,pH,BE and HCO_3~- were obviously reduced 30 min after anhepatic phase and in- creased 60 min after neohepatic phase.Kalemia was obviously increased 30 min following anhepatic phase and began to increase 60 min following neohepatic phase.Calium concentration was decreased at the end of preanhepatic phase(P

High glucose stimulated angiotensinⅡ(ATⅡ) production in mesangial cells of rat.Both high glucose and ATⅡdecreased expressions of matrix metalloprotein-9 (MMP-9) mRNA and MMP-9/tissue inhibitor of metalloproteinase-1 (TIMP-1) mRNA ratio and increased TIMP-1 mRNA expression in mesangial cells of rat,which could be reversed by an ATⅡreceptor blocker,Saralasin.

Objective To assess the quality of reporting randomized controlled trials published in Chinese journal of radiology from 2000 to 2005.Methods A manual search was performed and 22 checklists of CONSORT statements and other self-established criteria were applied.Results Six volumes and 72 issues were investigated.There were total trials of 236 in 2186 literatures,and finally 3 randomized controlled trials(RCTs)(1.27%)were identified.In the 3 RCTs,there were 3 trials with methods of randomization,1 with endpoints measurement,1 with multi-centre,but without the prior calculation of sample size,blind methods,statistically probability,participant flow,compliance and negative results.Conclusion The quality of reporting randomized controlled trials of interventional radiology has been improved,but it did not meet fully the CONSORT statement.

Objective To analyse the causes of perinatal death and explore the preventive measures to reduce the perinatal mortality.Methods The cases with perinatal death in this hospital from January 2005 to December 2006 were reviewed to analyse the causes of death by categorization and sum-up.Results There were 166 cases with perinatal death and the mortality rate was 27.08‰,including 126 cases with fatal death,which accounted for 75.90%.In the analysis of dead causes,the first one was birth defects,which suffered 69 cases,41.57% of all,and mostly were with fetus edema syndrome.The cord factors had been elevated to the second cause,which suffered 51 cases,30.72% of all.Conclusion Improving the consciousness of gestational monitoring and self-care,strengthening the prenatal diagnosis and genetic counseling,controlling the perinatal birth defects,monitoring mother and fetus by poly-parameter and stopping the pregnancy in time can reduce perinatal death effectively.
