Objective To analyze the evaluation value of ABCD2 combined with carotid ultrasound on the prediction of cerebral infarction after transient ischemic attack. Methods The clinical data of 133 patients with TIA admitted from July 2014 to December 2015 were analyzed. We score patients according to the standard of ABCD2 score and carotid ultrasound. The incidence of cerebral infarction within 7 days was observed. Results In the 133 TIA patients 35(26.3%) progressed to cerebral infarction. The 7-day incidence of cerebral infarction was 7.1% in patients with an ABCD2 score of low risk (0-3), 25% with a score of moderate risk(4-5), and 40% with a score of high risk(6-7). The difference of the incidence of cerebral infarction was significant between the low and moderate risk stratification (P < 0.05). The 7-day incidence of cerebral infarction was 39.5% in patients with carotid plaque and 75.0% in patients with carotid stenosis , both higher than the control group (P < 0.05). In the ABCD2 score ≥4 group, the incidence of cerebral infarction in the patients with abnormal carotid ultrasound was 38.4% ,significantly higher than the patients with normal carotid ultrasound (P < 0.05). Conclusions The ABCD2 score is effective to predict short-term risk of cerebral infarction in the patients with TIA. Combination with carotid ultrasound can improve the predictive accuracy of 7- day risk of cerebral infarction after TIA.

OBJECTIVE:To compare the efficacy and safety of only paroxetine vs. paroxetine combined with alprazolam in the treatment of diabetes complicated with anxiety and depression. METHODS:Totally 86 patients with diabetes complicated with anxi-ety and depression were randomly divided into observation group and control group. The patients in observation group were given paroxetine 20 mg,qd,and alprazolam 0.4 mg,tid;patients in control group were given paroxetine alone. The treatment course lasted for 8 weeks in 2 groups. The clinical data was compared,including fasting plasma glucose(FPG),2 h postprandial glucose (2 h PG),glycated hemoglobin (HbA1c),cortisol,adrenocorticotropic hormone (ACTH) levels and scores of Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD). The adverse reactions were observed. RESULTS:After treatment,FP-BG,2 h PG,HbA1c,cortisol,ACTH levels and scores of HAMA and HAMD in observation group were significantly lower than control group,with significant difference(P<0.05). There were significant differences in the incidence of adverse reactions be-tween 2 groups(P>0.05). CONCLUSIONS:Compared with paroxetine alone,paroxetine combined with alprazolam can improve more in blood glucose,endocrine levels and adverse mood symptoms in the treatment of diabetes complicated with anxiety and de-pression,with similar safety.

Objective To understand the molecular mechanism by which protein kinase C? mediates multidrug resistance of human glioma cell line SHG-44.Methods SHG-44/ADM was constructed by stepwise concentration increasing method and intermittent administration method.SHG-44/WT and SHG-44/ADM were treated by PKC? reactivator PMA and PKC? inhibitor staurosporine,then the expressions of PKC? and MDR-1 were detected by Western blotting,the PKC? activity was assayed by kinase,and ADM accumulation was determined by fluorescence spectrometry.Results PMA increased PKC? activity and MDR-1 protein expression and activity.Staurosporine was able to block PKC? activity and decrease MDR-1 expression and activity.Conclusion Multidrug resistance in human glioma cells is mediated by PKC? via MDR-1 pathway.

Objective To explore the lived study feeling and experience of nursing upgrade students during blended learning model so as to provide the evidence of reforming teaching model of nursing educators.Methods Phenomenological research of qualitative research was used.Four focus groups,25 upgrade nursing students were interviewed in-depth.Results Six themes were sublimated:relief the contradiction between work and study,promote communication in double interaction,improve self-learning ability,improve selfconfidence as learning controllability,online courses lack a sense of belonging,lack of skills support.Conclusions Blended learning model meets students,needs,provides students with personalized learning and improves comprehensive quality.However,the development of blended learning model in China is in the primary stage,we should combine conditions and reference foreign experience to develop it.

Objective To analyze the transcription level of new tumor suppressor gene SLC5A8 mRNA in colorectal cancer tissues.Methods Collected specimens of 23 cases with colorectal cancer and cut out carcinoma tissues and Pericarcinomatous tissue respectively,then used real time fluorescent quantitative PCR (RT-qPCR)to detect the transcription level of gene SLC5A8 mRNA,and the results of carcinoma tissues and pericarcinomatous tissues were analyzed by t test.Results The transcription level of new tumor suppressor gene SLC5A8 mRNA in colorectal cancer tissues is significantly lower than pericarcinomatous tissue (P =0.002).Conclusion The expression of gene SLC5A8 in colorectal cancer tissues is declining or missing,suggesting it has a certain relationship with the incidence of colorectal cancer.

To cultivate medical talents with innovative ability is necessary for quality education,medical development and medical mode transformation.The traditional education mode cannot acclimatize itself to innovation education.So,we should renovate the education concept,train students in innovative ability and put quality education into practice.

Objective To investigate the effect of parecoxib on cardiac function after acute myocardial infarction (AMI) in rats. Methods Twenty-four adult male SD rats, weighing 230-250 g, were randomly divided into 3 groups ( n = 8 each): group Ⅰ sham operation (group S), group Ⅱ AMI and group Ⅲ parecoxib (group P). Myocardial infarction was induced by ligation of left anterior descending branch (LAD) of coronary artery in group Ⅱ and Ⅲ . In group S, LAD and cervical sympathetic trunk were exposed but not ligated and transected.Group P received intrperitoneal parecoxib 8 mg/kg once a day for 3 days 24 h after ligation of LAD, while group AMI received normal saline instead. At 4th day after ligation LAD, the left ventricular systolic pressure ( LVSP),left ventricular end-diastolic pressure (LVEDP) and ± dp/dtmax were measured and recorded. Blood samples were taken from common carotid artery to determine the plasma concentrations of TXA2 and PGI2 and PGI2/TXA2 was calculated. Then the animals were sacrificed and hearts removed. Myocardial infarct size of left venicle was calculated. Results Compared with group S, LVSP, ± dp/dtmax, plasma concentrations of PGI2 and PGI2/TXA2 were significantly decreased, while LVEDP and plasma concentrations of TXA2 increased in group AMI and P( P ＜0.05). Compared with group AMI, LVSP, ± dp/dtmax, plasma concentrations of PGI2 and PGI2/TXA2 were significantly decreased, while LVEDP and plasma concentrations of TXA2 increased in group P ( P ＜ 0.05). There was no significant difference in myocardial infarct size between group AMI and P (P ＞ 0.05). Conclusion Parecoxib can improve cardiac function after AMI in rats and the mechanism is related to regulation of the balance of PGI2/TXA2.
