Objective To investigate the changes of serum vascular endothelial growth factor (VEGF) and its effects on pathoge nesis in children with Henoch - Schonlein purpura(HSP). Methods Serum VEGF was detected by sandwich ELISA in 20 children with HSP in acute phase and 15 children in remission phase and 16 normal children. Results The serum VEGF levels in children with HSP in acute phase(533.85? 127.63) ng/L were significantly higher than those in remission phase (160.47 ? 37.39) ng/L and normal control (68. 93 ? 19. 16) ng/L. One - way analysis of variance between them was significant difference ( F = 158. 86 P

Malignant gliomas are the most common intracranial tumors,with a highly invasive nature and a poor prognosis. The invasion of malignant gliomas is a complicate and consecutive multi-step process that includes adhesion, degradation and migration and involves various factors such as cell adhesion molecules, enzymes, and cytokines. Research on the invasive properties of malignant gliomas will advance our understanding of their underlying biological behavior and improve clinical treatment.

Objective:To study the clinical significance of examining serum pyridinoline cross-linked N-telopeptides of type I collagen(NTx) and serum bone sialoprotein(BSP) in diagnosing bone metastasis of lung cancer and breast cancer.Methods:A total of 105 patients treated in the Oncology Department of Changhai Hospital were included in this study.Patients were divided into 2 groups:bone metastasis(n=50) and non-bone metastasis groups(n=55).The levels of serum NTx and serum BSP were measured by ELISA.Results:The levels of serum NTx and serum BSP in patients with bone metastasis were significantly higher than in those without bone metastasis(P

Objective:To assesss the effectiveness of dapoxetine in the treatment of premature ejaculation.Methods:Both English and Chinese studies involving men with prematrue ejaculation who were treated with dapoxetine from the Cochrane Library,MEDLINE,EMBASE and CNKI,CBM,VIP between 1979 and 2009.were included in the randomized controlled trials(RCTs) and the data processed by RevMan.Results:Five RCTs involving 4433 patients were included in the Meta analysis,of which 3 were of grade A and 2 were of grade B according to the quality evaluation of methodology.Intravaginal ejaculatory latency time(IELT),patient-reported global impression of change(PGI),satisfaction with sexual intercourse(SWSI),perceived control over ejaculation(PCOE),personal distress related to ejaculation(PDRE) were used for assessment.Meta analysis based on included studies of patients having been treated with dapoxetine for 9-24 weeks showed that:(1) the difference of the patients' IELT between treatment group and control group was statistically significan [P

Objective To investigate the modulation of FasL protein in colon cancer cells by interleukin 18 (IL 18) and it's effect on tumor cells counterattacking T lymphocytes. Methods By using Western blotting assay, FasL protein expression was examined in human colon cancer cell line SW620. The ratio of apoptosis of lymphocytes induced by tumor cells was studied by flow cytometry analysis. Results 10 ?g/L and 100 ?g/L IL 18 upregulated FasL protein expression in SW620 cell line, reaching the peak in 18 and 36 hours respectively, and returned to initial levels in 72 hours. The ratio of apoptosis of Jurkat cells induced by tumor cells increased in accordance with the upregulation of FasL protein. Conclusions IL 18 upregulates FasL protein expression in colon cancer cell line and enhances the ability of cancer cells to counterattack T lymphocytes.

Objective To evaluate the effects of Lipo prostaglandin E1(Lipo-PGE1) on the lower limb blood vessel in diabetic patients.Methods The study was performed in 36 patients with diabetes related lower limb vascular disease.Before and after Lipo-PGE1 treatment for 28 days,vascular diameter and blood flow velocity of femoral artery,popliteal artery,posterior tibial artery and dorsal pedal artery were measured by Doppler ultrasonography examination.Results After the treatment with Lipo-PGE1,the vascular diameters of femoral artery,popliteal artery,posterior tibial artery and dorsal pedal artery were dilated;and there were significant differences in posterior tibial artery and dorsal pedal artery.After the treatment with Lipo-PGE1,blood flow velocity of femoral artery,popliteal artery,posterior tibial artery and dorsal pedal artery were increased,however,there were no significantly statistical differences.After the treatment with Lipo-PGE1,all the patients feel well.Painless walking distance and maximal walking distance of 18 patients with intermittent claudication were increased.Conclusion Lipo-PGE1 causes a significant improvement of diabetes related lower limb vascular disease.Furthermore,the results demonstrated the major effects on posterior tibial artery and dorsal pedal artery.Lipo-PGE1 can dilate the smaller artery,which is important and helpful for patients to improve symptoms and signs.
