Objective To explore the effect of TBL based on evidence-based medicine PICOS model in practice teaching of neurology. Methods Totally 47 medical undergraduates in our department were chosen and randomly divided into 2 groups during March 2016 to April 2016. 24 students in the trial group were taught with TBL based on PICOS, while other 23 students in the control group were only taught with conventional TBL method. After three times clinical practices, the test referring to disease pathogenesis, clinical manifestations, auxiliary examinations, diagnosis and treatments of related diseases was performed, and meanwhile, questionnaires were distributed to students in order to survey their satisfaction degree of teaching methods. All the evaluation results and scores of two groups were compared. Statistical data were analyzed by using t-test or Chi-square test with SPSS 17.0 software. Results The score of the theoretical test of trial group was significantly superior to the control group [(89.08±3.60) vs. (79.09±7.75), t=5.707, P=0.03 ]. Survey showed that in the experimental group , the number of students in the trial group who thought teaching method could help understand clinical thinking of neurology and could help integrate the theory into clinical practicewas significantly higher than that in the control group (P<0.05). Conclusion In the clinical teaching of neurology, the TBL based on PICOS model is more effective than conventional TBL method for medical undergraduates.

SHG was sulfated by chlorosulfonic acid-pyridine method, and six samples which we got were prepared in different reaction conditions. There is a characteristic absorption peak near 260 nm in UV spectra and there are two characteristic absorption peaks near 1240 cm(-1) and 810 cm(-1) in the FT-IR. Degree of sulfation (DS) was calculated by elemental analysis and turbidimetry. Under the same conditions the absorption peaks become strong with the DS increase. The anticoagulant activity of SHG and sulfated modification samples was evaluated by the classic coagulant assays of prothrombin time (PT), activated partial thrombin time (APTT) live enzymes, and plasma thrombin time (TT). Results show that sulfated SHG has a good anticoagulant activity in vitro, and DS increased activity within a certain range.

Objective To investigate the change of plasma visfatin in patients with coronary heart disease and its clinical significance.Methods A total of 310 patients with coronary heart disease (ACS group:n =217; SAP group:n =93) and of 90 healthy subjects with a matched age and gender were included in this study.The plasma concentration of visfatin of each subject was measured using ELISA assay,and each patient underwent selective coronary angiography examination.A total of 85 cases of patients in CHD group underwent 64-slice CT coronary imaging to evaluate the main plaque within the coronary.Results The visfatin,LDL,BMI,blood glucose levels was significantly higher in CHD group[ ( 128.18 ± 13.86)ng/ml,(3.63 ± 1.48) mmol/L,( 26.18 ± 1.82) kg/m2,(7.25 ± 2.03 ) mmol/L] than in control group [ (75.96 ± 10.27 )ng/ml,(2.64 ± 0.53 ) mmol/L,( 23.51 ± 0.89 ) kg/m2,(5.11 ± 1.53 ) mmol/L,P < 0.05 ],respectively.The visfatin level in the ACS group [ ( 145.57 ± 19.95 ) ng/ml ] was significantly higher than the SAP group [ (110.79 ±7.78)ng/ml,P <0.05].The visfatin concentration gradually increased with the aggravation of the complexity of coronary lesion types and severity of coronary lesions( P < 0.05).The plasma visfatin concentrations in Soft plaque group and the fibrous plaque group were significantly higher than calcified plaque (P < 0.05).HDL-C and Gensini score of coronary lesions were negatively correlated ( r =- 0.055,P <0.05) ; LDL-C,Glu,and visfatin was positively correlated with coronary lesions Gensini score ( r =0.464,0.279,0.531,P < 0.05 ),respectively.Conclusions The plasma visfatin level in patients with Coronary heart disease increased and affected its lipid metabolism.It may be an important inflammatory factors promoting arterial atherosclerosis occurs and development,which has a certain value to the judgment of coronary lesions and plaque stability combined with 64-slice spiral CT examination.

Objective:China was categorized as one of the 68 countdown countries to achieve the United Nations Millennium Development Goals (MDG) 5. This paper aimed to analyze the situation of maternal survival, and coverage of proven cost effective interventions in China, where specific attention was paid to disparities. Methods: National maternal and child mortality surveillance data were used to estimate maternal mortality ratio (MMR). Coverage for proven interventions was analyzed based on National Health Services Survey, where experts' consultations were made for complementation. Results: There had been a significant reduction of MMR in China, however great disparities existed, with rural Ⅱ to Ⅳ areas experiencing 2 to 5 times higher maternal mortality risks than urban areas and accounting for over 70% maternal mortality burdens. Postpartum hemorrhage, pregnancy associated hypertension, embolism and sepsis were the leading causes, and over 75% of the maternal mortality was caused by preventable or curable causes. Maternal health services utilization decreased in accordance with region' s development level. Socioeconomic factors like financial difficulties were the main obstacles hindering access of care.Even those who made deliveries in hospitals faced different probabilities in receiving qualified care according to their socioeconomic standings. Conclusion: China is on track to achieve MDG 5, however great disparities exist. It is necessary to specifically target rural types Ⅱ to Ⅳ areas. Major causes of maternal mortality which can be prevented or averted through the provision of essential obstetrical care. Yet as compared with maternity health needs, insufficient coverage of maternal and child health (MCH) care services and poor service quality are the leading predisposing factors contributing to maternal mortality in China.

Objective To explore the method of the major hospital indexes examination using clinical pathway as an opportunity.Methods Based on the material of our hospital from 2008 to 2010,reference the data of the same level hospital in Xinjiang Uygur Autonomous Region,we set the benchmark and formulated the examination standard of three examination indexes:average length of stay (ALOS),average hospitalization expense and drug proportion.Meanwhile,we took the subentry incentives to give the corresponding reward to clinical departments according to the decreases rate compared with the benchmark monthly.Results ALOS,average hospitalization expense and drug proportion of department and the whole hospital were obviously decreased compared with the same period last year,and the differences were statistically significant (Medical system:t =27.479,14.462,11.362,all P < 0.01 ; Surgical system:t =18.944,16.029,12.071,all P < 0.01).Conclusion After using the examination methods and combining clinical pathway,the effects are obvious,which can effectively shorten ALOS,reduce average hospitalization expense and drug proportion,so as to relieve the patients' economic burden.

Aerenchyrna formation has been described in depth in a number of species at a histological level. But large gaps remain in our understanding of its regulation as a developmental process. It is attempted to analyse essential mineral elements like K, Mg, Cu, Zn, Ca and P in the cell wall of aerenchyma cells in petioles ofS. trifolia at five different developmental stages by CSEM-EDX technique. At early stage, K and Cl concentrations in cell wall were high up to 36% and 4.3% of dry weight, respectively. It supported the hypotheses that aerenchyma spaces are filled with liquid at early developmental stages of aerenchyma in S. trifolia petiole. Mg concentration was high at stage 2, up to 0.86% of dry weight. Zinc and Cu were detected only at rapid expansion stages, during which the concentrations were up to 1.5% and 2.5%, respectively. Calcium was detected in the cell wall only at mature stages, the concentration was high up to 1.3% of dry weight at stages 4 and 5. These results confirmed that the element concentration of aerenehyma cell wall undergoes dynamic changes during different developmental stages, and a low Ca with high Zn and Cu concentration are needed for cell expansion. Copper and Zn deposition in the cell wall showed a significant positive linear correlation, suggesting that these two elements share same or similar uptake and transport mechanism in plants.
