Objective To investigate the value of early hematocrit (Hct) level in predicting early neurological deterioration (END) in patients with acute ischemic stroke. Methods The patients with acute ischemic stroke within 24 h of onset were enrolled prospectively. They were divided into low Hct, normal Hct, and high Hct according to the quantile of the measured Hct. END was defined as an increase of ≥2 of the National Institute of Health Stroke Scale (NIHSS) score or ≥1 of the motor item score within 5 d after admission compared with the baseline. The vascular risk factors, clinical features, baseline NIHSS score, infarct size, and laboratory test variables were compared between the END group and the non -END group. Multivariate logistic regression analysis was used to identify the independent risk factors for END. Results A total of 216 patients with acute ischemic stroke were enrolled, including 128 males (59.26%). Their mean age was 67.40 ±14.12 years. Sixty-two patients (28.70%) experienced END. The normal ranges of Hct in male and female were 40.12%-46.35% and 38.32%-44.17%, respectively. Univariate analysis indicated that there were significantly differences in baseline NIHSS score ( P =0.001), fasting glucose (P =0.030), C reactive protein (CRP) (P =0.041), and the proportions of different Hct levels between the END group and the non-END group (P =0.023). The END incidences in patients with high -level Hct (40.0%) and low –level Hct (35.2%) were significantly higher than that in the normal Hct patients (20 .4%), but there was no significant difference between the high-level and low -level Hct patients ( P = 0.690). Multivariate logistic regression analysis showed that theigh-level Hct (odds ratio 2.460, 95% confidence interval 1.146-5.283; P =0.021) and the baseline NIHSS score (odds ratio 1.070, 95% confidence interval 1.014-1.129; P = 0.013) were the independent risk factors for END. Conclusion The elevated Hct in patients with acute ischemic stroke are susceptible to END.

OBJECTIVE:To provide reference for the reform of the postgraduate training mode of pharmaceutical professional degree. METHODS:Domestic literatures about postgraduate training mode of pharmaceutical professional degree from 2010 to 2013 were searched and combined with the current education situation in China to conclude and summarize the existing problems and reform strategy. RESULTS:Postgraduate education mode of pharmaceutical professional degree in China was still in the explor-atory stage,with shortage of teachers,unreasonable courses,unsound educational structure,nonsupport of the students,imperfec-tion evaluation systems,and so on. Further promoting the reform of postgraduate education mode needs to strengthen teacher teams ’construction,implement cooperative training;improve training program and teaching courses;strengthen dissertation applica-tion-oriented and practice base construction;fully mobilize the enthusiasm and motivation of students;promote the connection of pharmaceutical professional training and vocational qualifications;and improve the quality assurance systems. CONCLUSIONS:Further implementation of postgraduate training mode of pharmaceutical professional degree and postgraduate education of pharma-ceutical professional degree can train the applied talents that meet social needs,improve employment rate of postgraduates and re-duce waste of educational resources.

Objective To analyze the clinical efficacy and adverse reactions of desloratadine citrate decre-mental therapy in treatment of chronic urticaria.Methods 162 cases of patients with chronic urticaria were selected, they were randomly divided into observation group and control group.Control group was given routine treatment of desloratadine citrate capsule,while the observation group was given desloratadine citrate capsule decreasing therapy, the therapeutic effect and the levels of serum immunoglobulins were compared between the two groups.Results After treatment,the total effective rate of the observation group was 95.06%,there was no significant difference compared with 92.59% of the control group (χ2 =3.254,P >0.05);Two weeks and four weeks after treatment,IgE levels were significantly lower than before treatment,there were significant difference (t =8.291,7.931,6.936,5.152,all P <0.05),and the observation group change was more significant,the differences between the two groups were statistically significant (t =7.913,8.136,all P <0.05).After treatment symptom score was significantly lower than before treat-ment,and there were significant difference (t =7.519,8.015,all P <0.05),but the differences between groups were not significant (t =3.152,2.781,all P >0.05).The recurrence rate in the treatment group was 19.75%,which was significantly lower than the 40.74% of the control group,the difference between the two groups was statistically signif-icant (χ2 =6.914,P <0.05).But there was no significant difference in the incidence of adverse reactions between the two groups (χ2 =1.927,P >0.05).Conclusion Desloratadine citrate capsules in treatment of chronic urticaria can not only obtain more effective clinical curative effect,but also has less toxic side effect.For the purposes of the application method of the drug,decreasing method compared with conventional medication therapy can effectively improve the level of serum IgE.Therefore,it is worthy of clinical application.

OBJECTIVE To explore the genotype and distribution of humam papilloma viruses(HPV) among rural women with cervical lesion.METHODS The cervical exfoliated cell specimens were collected and divided into two groups,the experimental group with 340 rural women finally diagnosed as cervical intra-epithelial neoplasm(CIN) or higher grade pathological changes in healthy examination,and the health control group with 230 rural women randomly selected from the crowd taken healthy examination.DNA was extracted and the genotypes of HPV-DNA were monitored by traditional nested PCR,flow-through hybridization and gene chip technique.RESULTS One-hundred and ninety-five cases(57.4%) in experimental group and the 58 cases(25.2%) in control group were confirmed to be HPV-DNA positive.There was significant difference between the two groups(P

Objective To explore the clinical significances of total antioxidation (TAO) and nitric oxide synthase (NOS) expression in patients with liver diseases.Methods The concentrations of TAO,NOS and nitric oxide(NO) were determined and the mechanism of their changes were analyzed in sera of patients with acute hepatitis(AH),chronic hepatitis(CH),liver cirrhosis(LC) and hepatocellular carcinoma(HCC).Results The abnormal rate of TAO was 80% in AH or in CH,and 50% in LC or in HCC,respectively.The sera NOS activity over normal reference value was 70% in patients with liver diseases.The abnormal rate of NO level was 70% in AH,CH and LC groups,and 48% in HCC,respectively.The average level of serum TAO was significantly higher in AH group or in CH group,but not in both HCC and LC groups than that in normal subjects.The average levels of NO and NOS were significantly higher in patients with liver diseases than those in normal subjects.However,the two markers were lower in HCC patients than those in AH,CH and LC groups,respectively.Conclusions The data suggest that the activity of NOS is close relation to serum NO level in patients with liver diseases,the increase of NO concentration may play a role in protection of hepatocytes.

Objective:To evaluate the value of 2D-3D registration method which combines improved mutual information and image pyramid.Methods:The continuous image representation of the cubic B-spline curve and Parzen histogram estimation were fused into the algorithm. The chest was used as the research object. The reconstruction of the orthogonal X-ray image generated by the radiographic image and the image after a certain transformation with itself were used for registration experiments to study the registration accuracy and time.Results:After 50 sets of controlled experiments, compared with the traditional registration method, the displacement accuracy of this method in the X and Y directions was improved by 53.39% and 21.33%, and the registration time was shortened by 91.93%. Compared with the modified algorithms in recent years, the displacement accuracy of the improved algorithm in the X and Y directions was increased by 17.65% and 13.79%. And the registration time was further increased by 19.64%.Conclusions:This method can effectively improve the registration accuracy and efficiency of 2D and 3D images, and both meet the requirements of image registration within 2 mm during surgery. The high efficiency and accuracy of this method provide beneficial information for clinical diagnosis and radiotherapy automation, which also lays the foundation for tumor position error correction and automatic positioning of medical robotic arms.
