Objective: To chine and express the recombinant human endothelial monocyte-activating polypeptide-Ⅱ(EMAP-Ⅱ)and identify its anti-tumor biological activities.Methods: EMAP-Ⅱ_(147-312)was expressed by the expression vector pMAL-p2x and E.coli BL-21 and the product was purified.The production of tissue factor(TF)in human umbili- cal vein endothelial cell ECV-304 mediated by the recombinant EMAP-Ⅱwas determined by chemiluminescence sub- strate.The promoting effect of recombinant EMAP-Ⅱon TNF?-induced ECV-304 cell.Apoptosis was determined by flow cytometry.Its inhibitory effect on human pancreaic cancer cell SW1990 proliferation was determined by MTT method. Results:DNA sequencing verified that EMAP-Ⅱwas correctly cloned.The molecular mass of the protein identified by SDS-PAGE was consistent with the theoretic value.The productivity of recombinant EMAP-Ⅱwas 500?g per 1 g bacteria (wet mass).The purified product induced expression of tissue factor(TF)in ECV-304 cells;it also enhanced the sensi- tivity of ECV-304 cells to the apoptotic effect of TNF?([16.6?2.5]% vs[25.6?2.3]%,P

Objective To establish the model of P2 peptide-induced experimental autoimmune neuritis(EAN)in rats and explore the roles of Th_1/Th_2 type eytokines in EAN.Methods Lewis rats were grouped into EAN rats and control rats.The EAN rats were immunized by injection into both hind footpads of inoculums containing 100 ?g or 200 ?g of P2_(57-81)peptide and FCA while the control rats were immunized with FCA only.Clinical scores were compared at the maximum of disease.Supernatant productions of IFN- ?, IL-4 and IL-10 secreted by lymphocytes and obtained on day 14 after the immunization were examined. Histopathological assessment of sciatic nerves was made.Results Peak clinical scores of P2_(57-81)200 ?g (3.6?0.3)group were significantly higher than P2_(57-81)100 ?g group(2.2?0.6,P

Objective To observe the effect of multiple interventions on secondary epilepsy patients.Methods 114 secondary epilepsy patients were randomly divided into the intervention group and control group with 57 cases in each group.The cases in the intervention group received multiple interventions including heath education,psychological treatment,safety nursing,overdose administration,early rehabilitation,discharge guide and so on besides usual nursing.While,the cases in the control group received usual nursing.The follow-up was performed for 6 months and the therapeutic efficacy of two groups was compared.Results After multiple interventions,the seizure frequency and trauma incidence rate decreased,compliance and quality of life increased in patients of the intervention group,and there was a significant difference compared with the control group(P<0.05).Conclusion Multiple interventions can decrease seizure frequency and increase compliance of treatment and quality of life of secondary epilepsy patients.

Objective To evaluate the predictive value of plasma levels of soluble vascular endothelial growth factor receptor 1(VEGFR-1,also known as sFlt-1) in second-trimester for preeclampsia.Methods One hundred and forty-six pregnant women with normal blood pressure previously were prospectively included in the study.Peripheral venous blood samples were obtained between 20 and 26 gestational weeks.Plasma levels of sFh-1 were measured by an enzyme-linked immunoassay.Results (1) Among 146 previously normotensive women,12 developed preeclampsia (preeclampsia group), 134 remained normal pregnant till the end (normal group).(2) The plasma levels of sFh-1 in preeclampsia group [(4135?699)ng/L] was significantly higher than that in normal group[(1490?1033)ng/L](P

A remarkabale inhibitory activity was exhibited by the aqueous extract from Rhizoma smilacisglabrae(RSG) against both picryl chloride(PC)- induced contact dermatitis and sheep red bloodcells (SRBC)- induced footpad reaction.The effect of RSG was displayed more distinctlywheng given after than before the 2nd antigen challenge.RSG also showed a marked anti-in-flammatory activity against xylene- induced ear and egg whiteinduced footpad edema.Addi-tionally,RSG did not show a potable influence on IgM- and IgG-PFC counts against SRBC inmice.An increase but not decrease in serum hemolysin level,however,was observed in both groupsof RSG,peralleled with the finding that hemolytic plaques in PFC test were obviously biggerthan those in control.These results suggest that RSG has a selective activity to suppress the cellularimmune response without inhibiting the humoral immune response.The suppression to cellular im-munity by RSG may be presented mainly through affecting the inflammatory process after lym-phokine release.

Objective To observe the influence of ATP protection after brachial plexus injuries. Methods A total of 80 female Wistar rats,weighting 280～300 g,were randomly divided into ATP and con- trol groups.The right C_5～T_1 nerve roots were transected and then the intraperitoneal injection of 4m[ of ATP or normal saline was given immediately and once daily to the rats,respectively.The rats were sacrificed on postoperative days 14,28 and 42 respectively.The C_5-T_1 segments of the spinal cord were harvested.NT-3 activity was measured by enzymo-histochemistry method.Four weeks and 6 weeks postoperatively,ultrastruc- ture of the denervated skeletal muscles was observed.Results Compared to the control group,the expres- sions of NT-3 was increased in the treated groups with ATP injection (P

Background and purpose:With the recognition of prognostic factors and application of surgical- pathological staging,the treatment strategy of endometrial cancer has greatly changed.In this study,we investigated the treatment strategy,survival rate and prognostic factors of endometrial cancer.Methods:Five hundred and fifty-nine patients of endometrial cancer underwent primary surgical treatment from January 1996 to December 2006 in Cancer Hospital,Fudan University.The clinicopathologic parameters and prognosis were analyzed retrospectively.Results: Patients were followed up with the median period 36 months,25 cases experienced local relapse,24 cases were found to have distant metastases.The 3-year overall survival(OS)was 88.7%,3-year and 5-year disease free survival(DFS) was 82.7% and 80.9%.The 3-year overall survival(OS)were 95.5% in stageⅠ,95.3% in stageⅡ,75.9% in stageⅢand 32.4% in stageⅣrespectively(P

BACKGROUND: Primary progressive aphasia(PPA) is a degenerative disease of nervous system, which is very rare in clinics. Only 3 cases have been reported in our country. There is very little clinical information regarding the characteristics of PPA in linguistics and imageology.OBJECTIVE: To report the language disorder and the characteristics of imageology of one PPA patient for the clarification of the clinical features of PPA.DESIGN: A case analysis.SETTING: Department of Neurology, Beijing Tiantan Hospital; Faculty of Psychology, Beijing Normal University.PATICIPANT: Male, 56 years old, senior high school graduate, businessman before the onset of the disease. The case visited the department of Neurology,Tiantan Hospital, Beijing due to the complaint of three years of progressive decreasing in language skills, which was then diagnosed with PPA.METH ODS: Spoken language fluency evaluation in Chinese Aphasia Examination Set of the First Affiliated Hospital of Beijing Medical University was used to evaluate this patient, the type of Aphasia was judged by Western Aphasia Examination Set, and the severity gradation was classified by the Boston Diagnostic Aphasia Examination(BDAE) . Memory, intelligence screening and imageology examination were performed as well.MAIN OUTCOME MEASURES: The fluency of spoken language, the type of aphasia, and the severity of aphasia of the patient were judged, and whether the patient suffered from memory and intelligence disorder were observed as well as the features of imageology.RESULTS: The patient had fluent spoken language, which was evaluated as sensory aphasia(SA) with the aphasia severity of level 4, and had no memory or intelligence disorder. MRI showed atrophy in left frontal lobe and temporal lobe, which was more significant in left side. MRI also showed that left temporal and frontal lobes had low metabolism and low perfusion.CONCLUSION: PPA is a disease with language disorder as its dominant clinical manifestation, which no other cognitive disorder at its initial stage,and with its main pathological changes in left temporal and frontal lobes.
