Objective To investigate the prognostic factors of young stroke patients with conventional treatment,and provide the basis for clinical diagnosis and treatment of stroke.Methods The clinical data of 72 cases of young stroke patients with conventional treatment were analyzed retrospectively.The prognostic factors were analyzed.Results In seventy-two cases of young stroke patients,18 cases of conventional treatment failed (25.00％,18/72).Univariate analysis showed that smoking,alcohol,underlying disease,dysphagia,barthel index (BI) score,U.S.national institutes of health stroke scale (NIHSS) score and Oxford handicap scale (OHS) score was closely related with the prognosis (P ＜ 0.05 or ＜ 0.01).Logistic analysis showed that the age,BI score,NIHSS score,OHS score and underlying diseases was the independent prognostic factor for young stroke patients.Eighteen cases who failed in conventional treatment fails accepted comprehensive rehabilitation treatment.Compared with that before treatment,1,3,6 months after treatment BI,NIHSS and OHS scores were significantly decreased (P ＜ 0.05).Conclusions BI,NIHSS,OHS score and underlying diseases are the independent prognostic factor for young stroke patients.Surgery and postoperative comprehensive rehabilitation in young stroke patients who failed in conventional treatment can improve patient's outcomes and prognosis.

OBJECTIVETo research the mechanism of dopamine (DA) controlled memory in mice.

METHODSMice received i.p. injection of scopolamine (0.3 mg/kg, SCOP 0.3, and 3.0mg/kg, SCOP 3.0, respectively, n = 10) and saline (NS, n = 10) for 60 days in experiment 1. Memory of mice was detected by dark avoidance behavior in the 53" d and the 60"' d. Animals were sacrificed after the memory test; brain tissues were processed for Fos-ir and TH-ir by immunohistochemistry. Mice were divided into four groups according results of expri-ment 1, they received i.p. injection of apomorphine (0.1 mg/kg, APO 0.1, 0.5 mg/kg, APO 0.5, and 2.0 mg/kg, APO2.0 respectively, n = 10).

RESULTSMemory was inhibited in mice injected scopolamine 3.0 mg/kg. Latency was significantly less than in NS group, only 1/ 4 that of NS group (P > 0.05). The number of mistake of SCOP 3.0 group increased about four times than that of NS group (P > 0.05). But there was no difference of latency and number of mistake between SCOP 0.3 and NS group in expriment 1. Scopolamine-induced memory deficit was associated with decreased cellular activation, indicated by Fos immunoreactive (ir) staining, in NAcc CA1 and CA3 (P < 0.05), and also associated with decreases in the number of cells labeled for tyrosine hydroxylase (TH-ir), the rate limiting enzyme for dopamine conversion (P < 0.01) and the number of cells co-labeled for TH-ir/Fos-ir (P <0.01) in the ventral tegmental area(VTA), apomorphine lessened scopolamine-induced memory deficit in experiment 2. The number of cells co-labeled for TH-ir/Fos-ir (P <, 0.05) was increased in VTA after apomorphine treatment.

CONCLUSIONApomorphine lessened scopolamine-induced memory deficit in mice by increasing DA activities in VTA.

Objective To explore the efficacy of GM6001,tissue inhibitor expression and significance of matrix metalloproteinase?9(MMP?9)in mice model of oxygen?induced retinal neovascularization(RNV)and evaluate the inhibition effect of MMP?9 inhibitor(GM6001)on RNV. Meth?ods Mice were placed in oxygen boxes to establish oxygen?induced RNV animal models. The GM6001 treated or hyperxia control groups received an intravitreal injection of 1μL GM6001(100μmol/L)or PBS at day 11 after birth. The normal control and hyperxia group were not treated. HE staining was used to detect RNV in retinal whole mounts,the mRNA level and protein expression of MMP?9 were measured by RT?PCR,Western blot and immunohistochemistry,respectively. Results RNV in the GM6001 treated group was decreased significantly compared with the hyperxia group and hyperxia control group. Compared with the normal control group,higher protein and mRNA expression of MMP?9 were observed in the hy?perxia group and hyperxia control group. The expression of MMP?9 protein and mRNA were decreased in the GM6001 treated group compared with the hyperxia control group(P<0.05). Conclusion The abnormal expression of MMP?9 was closely correlated with RNV. The development of RNV can be markedly inhibited by MMP?9 inhibitor(GM6001),which,we believe,will provide new molecular targets and therapeutic strategy for retinopathy of prematurity treatment.

Objective To assess the regional left ventricular (LV) rotation motion in the patients with rheumatic mitral stenosis (MS) with velocity vector imaging (VVI).Methods This study included 38 patients with isolated MS (mild,moderate and severe) and 55 healthy control subjects.Short-axis parasternal views at the basal and apical level of LV were taken.Peak value of rotation angle and rotation velocity,as well as time to peak value were measured by VVI workplace offline respectively.Results ①In the healthy control subjects LV rotates clockwisely at the base and counterclockwisely at the apex,the same as the patients with MS.② In th patients with MS,rotaion angle and rotation velocity were significantly reduced at the apical level(P ＜0.001),rotation velocity were significantly reduced at some segments of basal level (anterior,lateral,septal) (P ＜ 0.05).③Compared with the healthy control,the difference of time to peak roation angle between base and apex was significantly longer in patients with MS (P ＜0.05).④ There were no significant differences among mild,moderate and severe MS (P ＞0.05).Conclusions The patients with MS may suffer from systolic dysfunctin even in the early stage identified by the alteration of LV rotation motion,which is independent of the hemodynamic severity of MS.
