Objective To investigate the application of endovascular distal parent artery occlusion in vertebral artery dissecting aneurysms involving the posterior inferior cerebellar artery.Methods The clinical and follow-up data of 5 patients with vertebral artery dissecting aneurysms involving the posterior inferior cerebellar artery who received the endovascular distal parent artery occlusion were retrospectively analyzed.Results Complete occlusion of dissected arterial and aneurysm segments was achieved in 4 patients.After followed up 6-12 months,angiography showed no recurrence or neurological deficit.Continued filling of the dissected aneurysm was observed in 1 patient's follow-up angiography,but without rehaemorrhagia or neurological deficit.Conclusions The endovascular distal parent artery occlusion is a safe and efficient choice for treating vertebral artery dissecting aneurysms involving the posterior inferior cerebellar artery,which keeps the posterior inferior cerebellar artery flowing unobstructed while clipping the dissecting aneurysm.

Objective To investigate the changes of T cells and dendritic cells (DCs) and their related factors in children with immune thrombocytopenia (ITP) before and after therapy,and to analyze their clinical significance.Methods T-cells and DCs subsets were determined by flow cytometry both in 64 children with ITP (ITP group) before and after therapy and the control group.The serum levels of interleukin (IL)-4,interferon-γ (IFN-γ),transforming growth factor beta 1 (TGF-β1),and IL-27 were detected by enzyme linked immunosorbent assay (ELISA).Results Treatments of glucocorticoid or IVIg were effective in 41 cases of 64 ITP children.Compared to the control group,helper T cells (Th),Th/suppressor T cells (Ts),T regulatory cells (Treg),plasmacytoid DC (pDC),pDC/myeloid DC (mDC),and TGF-β1 in ITP patient group before treatment were significantly lower,while IFN-γ and IFN-γ/IL-4 were significantly higher (P <0.05).In ITP group,Th,Th/Ts,Treg,pDC,pDC/mDC,TGF-β1,and IL-27 were significantly increased,while IFN-γ and IFN-γ/IL-4 were decreased in children with ITP after therapy and achieved response (P < 0.05).However,there was no significant difference between before and after therapy in ITP children without treatment response (P > 0.05).Conclusions T cells and DCs subsets disorder and abnormal cytokine levels are observed in children with ITP,which can be corrected by immunosuppressive therapy,indicating that Th1 overactivity and the decrease of Treg and pDC both in quantity and function may be related to the pathogenesis of ITP in children.

Methods:An adenovirus expression vector with full length cDNA of p21 gene insert was constructed (ad p21) and transferred into SGC 7901 cell line with p53 mutation, the effects of ad p21 on the growth of SGC 7901 cell line was examined in vitro and in vivo . Results:The expression of p21 gene in SGC 7901 cell was confirmed by FCM, The growth of the Ad p21 gene transfected SGC 7901 cells was significantly inhibited as compared to mock (Ad LacZ) transfected SGC 7901 in vitro and induced the transfected cells appearing apoptotic, Combined with chemotherapeutic agent cisplatin (DDP), it could more strongly inhibit SGC 7901 cell growths.Conclusions:p21 gene can inhibit SGC 7901 cells growth and shows enhanced therapeutic efficiency for SGC 7901 cells when combined with DDP, especially in vivo experiment. Its use for gene therapy of cancer, especially when combined with other apoptosis inducing agents is promising.

Objective To discuss the valuable influence of the total-body massage on the facilitation of the rehabilitation for the women in puerperium.Methods Both Chinese traditional medical total-body massage and the biological information theories and its methodology were employed in dealing with 50 cases of puerperants without contraindications,who had labored naturally 12 hours before and who had received cesarean sections 48 hours before. The results were compared with the control group in which conventional preventive health care for puerperants was adopted.Results Notable differences exist in the aspect of lochia,defecation,lactation and emotions between the two groups.Conclusion Significant benefits can be obtained from the massage to facilitate the rehabilitation of the women in puerperium while promoting their quality of lives and broadening the coverage of services of the preventive health care for the puerperants.

BACKGROUND: Jaw defects are common clinically. It is desirable to find ideal seed cells combined with scaffolds to construct tissue engineered jaws for curing these diseases. OBJECTIVE: To investigate the growth characteristics of bone marrow mesenchymal stem cells (BMSCs) transfected with basic fibroblast growth factor (bFGF) gene after seeded on coral scaffold in vitro. DESIGN, TIME AND SETTING: An experimental study of bone tissue engineering was performed in the Research Institute of Stomatology, Sun Yat-sen University between March 2006 and June 2008. MATERIALS: Natural coral from China Hainan bench was made into pieces of 8 mm×8 mm×2 mm. METHODS: BMSCs were isolated from New England rabbits by density gradient centrifugation and then purified by adherent separation. bFGF-pcDNA3 gene was transfected into BMSCs using Lipofectamine TM 2000. bFGF gene-transfected (transfected group) or untransfected (untransfected group)BMSCs were seeded on different coral scaffolds. In addition, bFGF gene-transfected BMSCs were simply cultured but not on the coral scaffold for control (simple culture group). MAIN OUTCOME MEASURES: BMSC proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay and BMSC growth on coral scaffold was observed under the scanning electron microscope. RESULTS: MTT assay showed that the BMSC proliferation rate was significantly higher in the transfected group than in the untransfected group (P < 0.05) and that there was no significant difference in BMSC proliferation between the transfected and simple culture groups (P > 0.05). Scanning electron microscope results displayed that BMSCs adhered to and spread over the coral scaffold, exhibiting various appearances, with some cells had grown into scaffold micropores or spanned micropore surface, and some extracellular matrix secreted by BMSCs were found. CONCLUSION: The transfected group exhibited better growth of BMSCs transfected by bFGF gene than the untransfected group. These findings indicate that coral skeleton does not influence BMSC proliferation and can be used as a scaffold of BMSCs to construct tissue-engineered bone.
