Objective To analyze the clinical and histopathologic characteristics in children with subcutaneous panniculitis-like T-cell lymphoma(SPTCL),and explore the pathological diagnosis and differential diagnosis,in order to boost paediatricians to better understanding the disease.Methods One case was diagnosed SPTCL with over 2 years protracted course of fever and multiple skin lesions.The evolvement of clinical presentation,the misdiagnosed experience,the histopathological features,the immunohistochemical results and T cell receptor(TCR)gene cloning rearrangement were observed.The related literatures published were reviewed.Results Skin biopsy showed that the histopathologic findings were limited within subcutaneous fatty tissue,the atypical lymphocytes characteristically rimmed individual fat cells in a lace-like pattern.Immunophenotypic studies showed CD45,CD45RO,CD3,CD5,T cell intracellular antigen-1(TIA-1)and perforin usually expressed possitive,while CD10,CD20,CD56,CD68,epithelial membrane antigen(EMA)and cytokeratin(CK)were negative,implying tumor cells derived from T-cell.The results of TCR gene rearrangement as following:IgH FR2(+),FR3A(-);TCR ? JVI(-),JVII(+);TCR? JD1(-),JD2(-).Although the protocol of children's T-cell Non-Hodgkin lymphoma was administrated,the treatment outcome was poor.Conclusion SPTCL is a special primary cutaneous lymphoma with poor prognosis,skin biopsy of suffered lesion is an important method for the diagnosis of SPTCL children with unclear recurrent fever and multiple skin lesions.

By means of preparative HPTLC and column chromatography over silica gel and Sephadex LH-20, ten sesquiterpenes were isolated and purified from the whole plants of Solanum septemlobum Bunge. Based on the physico-chemical properties and spectral data, their structures were elucidated and identified as: lyratol D(1), solajiangxin B(2), 1 ,2-dehydrocyperone(3), solanerianone A (4), dehydrocarissone(5), ligucyperonol(6), nardoeudesmol A(7), solajiangxin F(8), and lyratol B(9), solajiangxin D(10). For the first time, compounds 1-10 were isolated from Solanum septemlobum, and compounds 5-7 were obtained from the genus Solanum.

Objective To compare the difference of protein and lipid metabolism between patients with inflammatory bowel disease and healthy controls,and to investigate the association of these changes with disease activity and location of the lessions.Methods The retrospective cohort study was carried out.The data of protein and lipid metabolisms collected from 195 patients with ulcerative colitis,76patients with Crohn's disease and 97 healthy controls during 1995 to 2007 were analyzed.Disease activity were evaluated using simple clinieal colitis activity index and simple index of Crohn's disease activity.The erythrocyte sedimentation rate(ESR)and C-reactive protein(CRP)were measured.Results Serum levels of ESR in patients with ulcerative colitis were negatively linear correlated with serum levels of albumin/globulin ratio(β=-0.521,P＜0.01)and positively linear correlated with serum levels of α2globulin(β=0.319,P＜0.01).Serum levels of globulin in patients with Crohn's disease were positively linear correlated with serum levels of ESR(β=0.558,P＜0.01)and CRP(β=0.424,P=0.01).In ulcerative colitis,serum levels of albumin/globulin ratio,albumin and total cholesterol were significantly higher in patients with proctosigmoiditis than those in patients with lesions at other locus(P=0.003,0.005,0.038,respectively).In Crohn's disease,serum level of globulin was significantly higher in patients with lesions only at colon than that in patients with lesions only at small bowel(P=0.029).Conclusions Serum levels of albumin/globulin ratio and α2-globulin can be predictors of inflammatory activity in patients with ulcerative colitis.The increasing serum globulin may predict the progression of disease activity in patients with Crohn's disease.The nutritional deficiency is more critical in patiens with small bowel involvement than those with colon involvement.

Objective To explore the relationship between the expression of syndecan-1 and the prognosis in pancreatic cancer. Methods The data of 30 patients with pancreatic cancer who received radical operations were retrospectively analysed.Immunohistochemical staining was performed,and the expression of syndecan-1 in tumor epithelial cells and stroma was observed by light microscopy.The relationship between immunohistochemical findings and survival was analysed.Results For those with negative,weak positive,moderate positive and strong positive expression of synecan-1 in tumor epithelial cells and stroma,there were significant differences in the case numbers between those survived for 1 to 2 years and those survived for 2 to 4 years(P

Objective To analyse the clinicopathological features of primary small intestine lymphoma(PSIL), and explore the relationship between clinical stage,histological findings,therapeutic modality and prognosis. Methods The clinical data of 34 cases of PSIL were collected,the pathohistological features and results of immunohistochemical examinations were obtained,and the follow-up findings were adopted for comprehensive analysis. Results Among these 34 cases of PSIL,abdominal pain or discomfort,gastrointestinal bleeding and abdominal mass were the predominant symptoms.PSIL mainly involved ileum,especially the bottom of ileum and ileocecal area.Among the 26 patients with follow-up for more than one year,the 1-year survival rate was significantly higher in patients without tumor perforation than those with tumor perforation(76.2% vs 20.0%)(P

Objective To establish a stable primary culture of rat cerebellar granule neurons in vitro for further study the toxic effects of chronic arsenic exposure on cerebellar cells.Methods Cerebellar cortices were taken from brain of Wistar rat 5-7 day old after born under stereoscopic microscope.Single cell suspension was acquired after digestion and washing with trypsin (0.25％) and DNase Ⅰ solution,respectively.Granule cells were purified from other cells by differential velocity adherence method for two times.Rat cerebellar granule neurons were seeded in culture plate pre-coated with poly-L-lysine.Neurons growth,development and synaptic connections were observed daily.The neurons were identified by neuron specific enolase (NSE) immunofluorescence technique.Results The neurons were affixed to the culture plate in 24 hours,in reticular arrangement observed under contrast microscope.Granule cells gradually turned round from oval and outlines became clearer in 2-3 days.In 4-6 days,there were a wide range of synaptic connections among the neurons and a mature nerve cell network formed.A large quantity of cerebellar granule neurons was seen by NSE identification.Few bigger cells such as purkinjes cells and glial cell outlines were also seen in the same visual field.Conclusions This is a successful primary culture method for acquirement of rat cerebellar granule neurons.The method can provide experimental basis for future studies the toxic effects of chronic arsenic exposure on cerebellar cells.

Objective To construct a system for three dimensional face scanning and measurement. Methods The measurement system was based on the principle of triangulation and the combination of gray-code and phase-shift structured light projection. The system software was developed for Windows XP with the aid of tools such as Visual C++ and Hoops. Results A three dimensional measurement system based on structured light projection was developed. The system hardware was composed of fringe projection unit, image gathering unit, system control unit and mechanical appearance, and the system software was composed of point cloud display and editing module. The lamp house of the system was 12V, the working distance was 900 mm, the scanning time was 5.5 s and the scanning field was 500 mm×400 mm. Conclusion The three dimensional measurement system based on structured light projection is a refined machine with safe light to eyes, and the accuracy and scanning speed are suitable to face scanning.
