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 explore the clinical effectiveness and safety of percutaneous vertebral augmentation with the Vessel-X bone void filling container system (Vesselplasty). Methods Three cases of fresh osteoporotic vertebral compression fracture were treated with Vesselplasty. After procedure, the pain relief, the fracture reduction, and the cement distribution in the vertebra were observed. Results All the 3 cases were treated with the unipediclar injection technique. The operative time was 45, 32 and 30 min, respectively. The hemorrhage volume was

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.

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.

AIM: To explore the effects of PMA(phorbol-12-myristate-13-acetate,a tumor promoter, mimicking the action of diacylglycerol on PKC)and laminin on the adhesion and the proliferation of human hepatocellular carcinoma cells, and provide a new clue to liver cancer treatment. METHODS: Human hepatocellular carcinoma cell line(BEL-7402)was used to identify the endogenous laminin and protein kinase C-?(PKC-?) expression, and the effects of laminin and PMA on the adhesion and the proliferation were also investigated in vitro. RESULTS: By the effect of exogenous laminin, human hepatocellular carcinoma cell (BEL-7402) possessed endogenous laminin expression and increased the adhesion and the proliferation, which was showed the synergistic action by the effect of PMA in combination. By the action of PMA alone,the proliferation and the PKC-? expression increased by exogenous laminin were decreased, and the adhesion and the endogenous laminin expression were increased. CONCLUSIONS: The finding suggested that the adhesion and the proliferation of human hepatocellular carcinoma cell were closely related to the effects of endogenous or exogenous laminin ,which were associated with cPKC-? activity. Therefore,the application of anti-laminin antibody in combination with PKC antagonist might be a new clue to find out the therapy for liver cancer.

Purpose:To study the effects and overexpression of p21 WAF1/CIP1 gene (p21 gene) on the SGC 7901 cell line plus cisplatin. 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.

The aim of this study was to look for the chemical constituents from the rhizomes of Dryopteris sublaeta. The fresh plant was extracted twice with boiling water, the extract was concentrated to small volume under reduced pressure at 50 ℃. The concentrated material was partitioned with ether, ethyl acetate and n-butanol. The fraction of ethyl acetate was repeatedly chromatographied over silica gel and Sephadex LH-20 columns. Structures of pure compounds were established on the basis of their physiochemical and spectral data. Nine compounds were obtained and identified as sublaetentin A (1), sublaetentin B (2), sublaetentin C (3), sublaetentin D (4), matteuorienate A (5), matteuorienate C (6), arbutin (7), 3-methoxy-4-hydroxyphenyl-1-O-β-D-glucopyranoside (8) and 3,4-dimethoxyphenyl-1-O-β-D-glucopyranoside (9). Compounds 1-4 are new compounds, the others were isolated from this plant for the first time.
