Objective To study the accuracy of plasma matrix metalloproteinase-9 (MMP-9) predicting hemorrhagic transformation (HT) in ischemic stroke. Methods The studies on plasma MMP-9 predicting HT in ischemic stroke were included, in which diagnostic criteria, methods, and subjects were clearly described, regardless of language of publication and type of studies. MEDLINE (Apr, 1966 to 2006), EMBase (Apt, 1966 to 2006), CNKI (Feb, 1977 to 2006), and wanfangshuju (1989 to 2005) were searched and the references lists of eligible studies were manually searched. Two reviewers independently evaluated the quality of studies and extracted data. The data were analyzed using the Revman 4. 2 or SPSS 11.0. Results Five trials including 497 patients fulfilled the inclusion criteria, 109 of the 497 patients developed HT. The heterogeneity among studies was great (xspecialty 89. 9% (95% CI: 86. 4%-93.5%), sensitivity 86. 5% (95% CI: 77. 3%-96. 8%). Conclusions The values of plasma MMP-9 may be an independent predictor of hemorrhagic transformation. The number of patients in the included studies is not large enough, and the results need to be confirmed in further studies.

Objective To investigate the effect of lacosamide on expression of Nav1 .8 in dorsal root ganglia (DRG) in a rat model of chronic neuropathic pain.Methods Thirty-six female specific-pathogen-free (SPF)SD rats were randomly assigned into 3 groups ( n = 12 each): sham operation group (group S), model group (group M) and lacosamide group (group L) . Chronic neuropathic pain was produced by insertion of a small stainless steel rod (4.00 mm in length and 0.63 mm in diameter) into the L, intervertebral foramen in the rat, producing a chronic steady compression of the DRG in M and L groups. The mechanical threshold was measured 2 days before operation and on the 2, 4, 6, 7, 8, 9 and 10 days after operation (T0-7 ) . Intraperitoneal lacosamide 20mg/kg (in normal saline 0.5 ml) was injected at T4-7, twice a day in S and L groups. In group M, normal saline 0.5 ml was injected at T4-7 twice a day and the mechanical threshold was measured after the last administration everyday . The L, DRG on the operated side was removed after measurement of pain threshold to detect the expression of Na, 1.8 mRNA and protein by RT-PCR and immuno-histochemistry respectively. Results Compared with group S, the mechanical pain threshold was significantly decreased at T1-7 and the expression of Navl .8 mRNA and protein was up-regulated in M and L groups ( P < 0.05) . Compared with group M, the mechanical pain threshold was significantly increased at T4-7 and the expression of Nav 1.8 mRNA and protein was down-regulated in group L ( P < 0.05) . Conclusion The mechanism by which lacosamide reduces chronic neuropathic pain is related to the down-regulation of the expression of Nav 1.8 in rat DRG.

Objective To sum up effective measures to prevent complications of peripherally inserted central catheter (PICC) by applying evidence-based nursing in patients after PICC insertion.Methods From January 2011 to January 2013,1490 patients inserted with PICC in Hunan Provincial Tumor Hospital were selected by convenience sampling,whom were divided into control group (n =758) and observation group (n =732) with random number table.The control group received routine care,while the observation group received evidence-based nursing.Nursing program for the observation group was formed based on literature regarding the causes of and solutions for phlebitis,malposition of PICC,infection of insertion sites,and hemorrhage of insertion sites.Results The incidences of postoperative phlebitis,malposition of PICC,infection of insertion sites,and hemorrhage at insertion sites in the observation group were significantly lower than those in the control group (3.14％ vs.8.97％,P=0.023;4.23％ vs.11.74％,P=0.021;3.96％ vs.8.44％,P=0.001;4.92％vs.12.66％,P =0.011).Conclusions The application of evidence-based nursing in patients with PICC insertion could effectively reduce the complication,and improve the quality of clinical nursing care.

Objective To study the releasing properties and mechanism in vitro of the active ingredients of the gastric floating sustained-release tablet containning Zuojin Pellet extraction(ZJ-GFST).Methods The release rates of berberine,palmatine,evodiamine,and rutaecarpine from ZJ-GFST in vitro within 8 h were measured by using rotating basket method in Chinese Pharmacopeia.The cumulative curve of drug release data was fitted to zero order,first-order and Higuchi equation to ascertain the kinetic modeling of drug release.Release mechanism was ascertained using Peppas equation.Results The similar factors of the cumulative release curve of all the four ingredients mutually compared were more than 80%,indicating that the release of the four ingredients were similar.The cumulative release rate of all the four ingredients fitted Higuchi equation.The value of slopes of Peppas models of all the four ingredients were more than 0.45,indicating that drug released by concurrent action of diffusion and matrix erode(non-fickian diffusion).Conclusion The releasing properties in vitro of the active ingredients of ZJ-GFST is consistent.
