Objective To evaluate the nursing methods of patients with ischemic cerebrovascular disease treated by intracranial stent. Methods 90 patients with ischemic cerebrovascular disease in our hospital during March 2006 to March 2010 were selected, their clinical nursing measures were summarized. Results All patients passed the treatment process, mean hospital stay was ( 19.8 ± 4.0)days. Conclusions Elaborate nursing to patients with ischemic cerebrovascular disease treated by intracranial stent can effectively reduce the average length of hospital stay.

AIM: To observe the effect of nonpenetrating trabeculectomy with implantation of amniotic membrane on the treatment of open-angle glaucoma.METHODS: Sixty-six cases (87 eyes) were randomly paired into 3 groups, treated with nonpenetrating trabeculectomy with implantation of amniotic membrane (22 cases, 29 eyes),compound trabeculectomy (22 cases, 29 eyes) and nonpenetrating trabeculectomy with implantation of SKGel (22 cases, 29 eyes), respectively.RESULTS: Compared with the other 2 groups, the group of nonpenetrating trabeculectomy with implantation of amniotic membrane got a better postoperative visual acuity (P＜0.01),satisfactively-controlled intraocular pressure (IOP) (P＜0.01)and fewer complications (P＜0.01).CONCLUSION: Nonpenetrating trabeculectomy with implantation of amniotic membrane is an effective method for the treatment of open-angle glaucoma.

Objective: To study the effect of apigenin on the expression of microglia in penumbra and cerebral water content after acute transient focal cerebral ischemia-reperfution injury in rats. Methods: The acute transient focal cerebral ischemia-reperfusion models in rats were established with the modified suture method. Male Sprague-Dawley rats were randomly divided into Sham group, model group, and apigenin groups (there were 6, 24, 48, 72 h, and 7 d reperfusion treatments in the model and apigenin groups, n = 12). All of them are 11 groups. The neurological behavior scores were valued. By FITC labeled isolectin B4 (FITC-ILB4) histochemistry staining, the infiltration of monocytes and the changes of cell morphology and number of brain-derived microglia in penumbra of six rats in every group were observed under laser scanning confocal microscope (LSCM). Water content was measured in isolated brain tissue of other six rats. Results: The positive cells of ILB4 (ILB4+) including microglia cells (Rhod 6G-) and infiltration of monocytes (Rhod 6G+) were found in cerebral ischemic area around penumbra of rats after 6 h ischemia-reperfusion in model group; The morphology changed to Amoeba-like; Microglia increased significantly after 48 h and reached to peak in 72 h, which mainly belonged to the proliferation of brain-derived microglia in Amoeba-like morphology. Microglia cell decreased in 7 d, and microglia in apigenin group obviously decreased more than that in model group (P<.05, 0.01) with the similar morphological change in corresponding time points. In 48 and 72 h of cerebral ischimia, the water content in brain tissue of rats in apigenin group was markedly lower than that in model (P<0.01). There was negative line correlation between the neurological behavior score and the number of ILB4 + cells in penumbra of model group (r=-0.415, P<.05). Apigenin could reduce the degree of neurological deficiency in model group and mitigate the brain injury effectively. Conclusion: A part of microglia cells inpenumbra are associated with brain injury; Apigenin shows the protection on acute transient focal cerebral ischemia-reperfution injury in rats, which maybe relates with down-regulating the microglia cell number and inhibiting the excessive activation of microglia cell.

Objective: To investigate the nootropic components of Hovenia dulcis. Methods: Six saponins were isolated from Hovenia dulcis and Step-down test was used to examine the memory ability of mice. The escape latency and the times of wrong performance within 3 min were used to evaluate the memory ability of mice. To study the effects of saponins on learning and memory in mice, we divided the mice into 6 groups: youth group, aged group, aged plus piracetam(0.3 g/kg) group, aged plus saponins (0.6 g/kg) group, aged plus saponins (0.3 g/kg) group, and aged plus saponins(0.15 g/kg) group. To study the influence of saponins on impairment of memory acquirement, consolidation, and reoccurrence (induced by scopolamine, sodium nitrite and 40% ethanol, respectively), mice were also divided into the following 7 groups: control group, untreated group, Piracetam group (0.3 g/kg), compound 3 group(0.3 g/kg), compound 4 group(0.3 g/kg), compound 5 group(0.3 g/kg), and compound 6 group (0.3 g/kg). Results: The chemical structures of six saponins were elucidated as 3-O-stigmasterol-(6-O- palmitoyl)-β-D-glucopyranoside (1), β-daucosterin (2), hovenidulcioside A1 (3), hoduloside I (4), hoduloside IV (5), and saponins C2 (6). Among them, compounds 1 and 2 were isolated from this plant for the first time. Compounds 5 and 6 had enhancing effect on the learning and memory ability of natural senile mice, and they could improve the impairment of memory acquirement, consolidation and recurrence in mice induced by scopolamine, sodium nitrite and 40% ethanol, respectively. Conclusion: The aglycone of jujubogenin might be the main saponins contributing to the nootropic effect of total saponins from Hovenia dulcis.

To compare the activity of RGD-TRAIL in different expression systems, RGD-TRAIL in both Escherichia coli (E.coli) and Pichia pastoris was constructed and expressed. In vitro activity of RGD-TRAIL from Pichia pastoris expression system was also analyzed. Genetic engineering techniques were used to construct recombinant plasmid pET30-rgd-trail and pHBM-rgd-trail. The recombinant protein RGD-TRAIL was purified with Ni ion affinity chromatography after induction. MTT assay, ELISA, scratch wound healing, transwell migration assay and Hoechst 33342 staining were performed to detect the effects of RGD-TRAIL on proliferation, binding activity, migration and apoptosis. The expression of apoptosis-associated proteins was detected by Western blotting. Recombinant protein RGD-TRAIL was successfully expressed in a form of inclusion body in E.coli, while expressed secretorily in Pichia pastoris. It possessed more potent cytotoxicity than RGD-TRAIL in E.coli by MTT assay. The RGD-TRAIL expressed by Pichia pastoris showed powerful binding affinity with cancer cells expressing α(v), DR4, DR5 and highly potent cytotoxicity through inducing apoptosis of cancer cells. Nuclear fragmentation was examined by Hoechst 33342 staining. Cleaved PARP and caspase-3 were also detected after incubation with RGD-TRAIL. Additionally, RGD-TRAIL inhibited migration significantly in A549 and HT1080 cells. The results demonstrate that Pichia pastoris expression system is more suitable for the recombinant protein RGD-TRAIL. Its binding affinity and antitumor activity might make RGD-TRAIL a promising candidate for cancer therapy.

Based on vector auto-regression (VAR) model, this paper takes advantage of Granger causality test, variance decomposition and impulse response analysis techniques to carry out a comprehensive study of the factors influencing the price of Chinese herbal, including herbal cultivation costs, acreage, natural disasters, the residents' needs and inflation. The study found that there is Granger causality relationship between inflation and herbal prices, cultivation costs and herbal prices. And in the total variance analysis of Chinese herbal and medicine price index, the largest contribution to it is from its own fluctuations, followed by the cultivation costs and inflation.
