OBJECTIVE:To compare the curative effects and pharmacoeconomical efficacy of three drugs in the treatment of patients with hypertension.METHODS:A total of 90 patients with hypertension were randomly divided into three groups:30(Group A) were treated with enalapril,30(Group B) with groLosartan,and 30(Group C) with metoprolol,all with a treatment course of 6wk.The clinical effects were observed and the cost-effectiveness analysis was conducted among the three schemes. RESULTS:The total effective rates of the 3 groups (A,B,and C) were 93.1%,96.7%,and 83.3%,respectively;the incidence rates of ADR were 10.3%,10.0%,and 16.7%,respectively;the cost-effectiveness ratios were 77.39,338.78,and 180.40,respectively;The incremental cost-effectiveness ratio of Group B and C were 7 098.61 and —798.16,respectively as against Group A.CONCLUSION:Group A(enalapril) treatment programs is a more reasonable drug program.

Results One hundred and seventy-one patients under surgery, including 67 PCOA aneurysm, 56 ACoA aneurysm, 32 MCA aneurysm, 10 ICA aneurysm, OphA aneurysm and 3 haimess aneurysm. Accoring to Glasgow Prognostic Scale, there were 3 cases of grade Ⅰ, 6 cases of grade Ⅲ, 14 cases of grade Ⅳ and 148 cases of grade Ⅴ. Conclusion The key points to cure intracranial aneurysms successfully is favourable exposure and the skills of microsurgery; the factors of intluent surgery include forcejudgement in surgery, reasonable choice of aneurysm clips, correctly block in arterious.

Objective To study the methods and significance of motor and sensory areas mapping by optical intrinsic signal imaging (IOSI) and neuromonitoring (IOM) during the operation on the lesions near the central sulcus. Methods Intraoperative neuromonitoring were firstly used to map the central sulcus and motor cortex in 5 patients with glioma undergoing surgery. Then, intrinsic optical signals imaging were used to locate the postcentral gyrus. According to the results of mapping, microsurgical operation was chosen for the resection of glioma and postoperative functional results were evaluated. Results All the patients acquired accurate location of central sulcus, motor cortex and somatosensory cortex. The enhanced MRI performed within 24 hours postsurgery showed total resection in 5 cases. The motor and somatosensory function of 5 patients returned to normal after 3-12 months. Conclusion Intraoperative location of the somatosensory area and motor area by optical intrinsic signal imaging and neuromonitoring is a reliable and safe method.

Isolation of rat gastric mucosal cells was performed with scraping method followed by protease and collagenase digestion. Parietal cells were observed and identified with phase-contrast microscopy, light microscopy with hematoxylin and eosin staining, electron microscopy, fluorescence microscopy, and also immunocytochemistry technique. The diameters of parietal cells were measured. The results showed that the mucosal cells were successfully isolated, and it was confirmed that the parietal cells were the biggest cells among all the mucosal cells.

Objective To study the properties of K~ +-ion channel of rat parietal cells, and to approach its effects on physiological and pathological process. Method Parietal cells were isolated. Electrophysiological records of K~ +-ion channels were made through whole cell's patch clamp technique, and the properties of the channels were analyzed. Results 10mM tetraethylammonium chloride may partially block the outwardly depolarized K~ +-ion channel current. While 10mM tetraethylammonium acetate, 10mM barium chloride or 10mM barium acetate may increases the outwardly depolarized K~ +-ion channel current. Conclusion The whole cell K~ +-ion channel current of rat parietal cells showed voltage sensitive. The current-voltage relations of whole cell potassium channels of rat parietal cells are both outwardly and inwardly rectified.

Objective To study the effect of TFF_2 gene theragy on the healing of experimental gastric ulcer in rats and its mechanism.Methods From Jun.10,2005 to Mar.15,2006.48 Wistar rats were randomly divided into two groups:24 in therapy group,24 in control group.pcDNA3.1-TFF_2 100?g was used in each rat in therapy group,and the same volume of pcDNA 3.1 was used in control group.Each rat was injected under serous membrane of the gastric wall after making model.The rats were executed separately after 3、7、14 days.Results Ulcer index was 9.7?2.9 mm2 in therapy group and was 17.7?3.1 mm2 in control group on the 14th day.There was significant difference between the two groups.The average amount of mucous glycoprotein was 83.35?4.54 mg/g in the therapy group and 70.36?4.22 mg/g in the control group.There was no significant change in the secretion of acid between the two groups.Conclusion TFF_2 gene therapy can promote the healing of experimental gastric ulcer in rats.Its mechanisms may include increasing mucous glycoprotein of the gastric wall without suppressing gastric acid secretion.

Objective To analyse clinical features of 86 cases of intracranial arteriovenous malformation (AVM) and explore strategies and methods of the microsurgical treatment of intracranial arteriovenous malformations.Methods The clinical data of 86 intracranial arteriovenous malformation from January 2010 to January 2013 were retrospectively reviewed.For diagnosis,computed tomography (CT) with angiography (CTA),and DSA were used,which could provide real size,location,feeding arteries and draining veins of AVM,and apply NEPM to evaluate the nerve function,assess the qualitative and quantitative flow rate of AVM and surrounding blood vessels by Doppler ultrasonography and fluorescein angiography,and reveal opography of AVM.Operative techniques were used including embolization,feeding artery control.Results Eighty-six cases of AVM were resected successfully under mutitechnology.Following-up demonstrated excellent neurological outcomes in 70 cases,nine case had mild disability,five cases had severe disability,two dead cases.DSA shows resected completely,and long-term follow-up was still in progress,conclusion Multi-technology combined microsurgical techniques which can effective improve the outcomes of intracranial arteriovenous malformations.

Objective To investigate the effects of methylthioadenosine phosphorylase (MTAP) on invasion and migration in breast cancer cells.Methods Human breast cancer cell line MCF-7 cells were treated with MTAPtargeted siRNA to diminish MTAP mRNA.MCF-7 cells proliferation was evaluated by cell counting kit-8,the analysis of cells invasion and migration was performed using Transwell chamber.The expressions of MTAP and matrix metalloproteinase 1 (MMP1) in cell extracts were detected by Western blotting.The experimental divided into blank contrd group,negative control group,MTAP-siRNA experimental group.Results The MCF-7 cells growth was promoted after knockdown the MTAP mRNA.MATP-siRNA experimental group 450 nm absorbance values at 24h,48 hand72 h of the control group were (112.3±11.9)％,(144.4±8.4)％,(169.3±9.4)％ respectively.Cell invasion analysis by Transwell chamber showed 570 nm absorbance values were 0.49 ± 0.06 (control),0.45 ± 0.07 (negative control) and 0.87 ± 0.07 (MTAP-siRNA) respectively.Cell migration analysis by Transwell chamber showed 570 nm absorbance values were 0.46 ± 0.06 (control),0.49 ± 0.08 (negative control)and 0.75 ± 0.07 (MTAP-siRNA) respectively.The expression of MMP1 in MCF-7 cells was upregulated after knockdown the MTAP mRNA.Conclusion The knockdown of MTAP in MCF-7 cell can increase the cells invasion and migration,and this may involve the the MMP1.
