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: This work aimed to construct stable MCF-7 cell sublines from which staphylococcal nuclease domain con-taining 1 (SND1) expression was interfered to analyze the effect of SND1 silencing on the proliferation and metastasis of MCF-7 cells. Methods: The lentivirus that could mediate SND1 silencing was prepared. MCF-7 cells were infected with the lentiviruses to construct stable sub-cell lines. Quantitative real-time polymerase chain reaction and Western blot analysis were employed to determine SND1 ex-pression level. MTS, wound healing, and transwell assays were applied to analyze the effect of SND1 silencing on the proliferation, mi-gration, and invasion of MCF-7 cells. Results: A lentivirus expression vector that contains sequences encoding shRNAs targeting SND1 and an shRNA negative control were successfully established. The lentiviruses (LV-SH1, LV-SH2, LV-SH3, and 和 LV-NC) were then collected and packaged. Stabilized MCF-7 sublines were prepared through infection with lentiviruses. The most efficient MCF-7 stable cell subline, MCF-SH3, was selected for SND1 silencing. Compared with the control cell, the proliferation, migration, and inva-sion potential of MCF-SH3 were significantly decreased. Conclusion: SND1 could promote the proliferation, migration, and invasion of breast cancer cells. Thus, silencing SND1 expression will inhibit such proliferation, migration, and invasion. These results indicated that the unusual expression of SND1 is associated with breast cancer and may participate in cancer progression by affecting prolifera-tion, migration, and invasion.

Objective:Pathological nipple discharge (PND) is commonly associated with benign breast disorders. However, PND lesions can also be malignant and can be the initial or unique presenting symptom of breast cancer. This study aimed to investigate the relationship between the clinical factors and the character of PND lesions. Methods:The clinical data of 207 patients with PND as their primary complaint were retrospectively analyzed. Results:Univariate analysis showed that the risk factors for breast cancer usually increase in patients with PND accompanied by a breast lump or breast calcification or those aged over 50 (P<0.05). The characteristics and course of PND were not correlated with the diagnoses of benign and malignant degrees of PND (P>0.05). Multivariate analysis indicated that patients aged over 50 with PND accompanied by a breast lump or breast calcification have a higher risk of suffering from breast cancer. Conclusion:The ages of patients with PND accompanied by a breast lump or breast calcification may significantly affect the diagnosis of benign and malignant PND lesions.

The application of high performance capillary electr ophoresis, aqueous two-phase system and reverse micelles extraction were also b riefly introduced. Besides, the foreground of these modern separation technolog ies was discussed.

To guide and encourage medical students to do grass-roots work,we need to strengthen the functions of the government work and employment guidance of medical colleges.Also,we have to improve the employment system of primary health care units and help students change their concepts about employment.
