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 develop a method for the concentration determination of olanzapine,risperidone and paliperidone in human plasma.METHODS:After liquid-liquid extraction,using buspirone hydrochloride as internal standard,the concentration of plasma sample was determined by UPLC-MS/MS.The determination was performed on ACQUITY UPLCTM BEH C18 column with mobile phase consisted of methanol-0.01 mol/L ammonium formate solution (gradient elution) at flow rate of 0.2 mL/min.The column temperature was 45 ℃,and sample size was 5 μL.The electrospray ionization source was adopted for positive ion scanning under MRM mode.Ion-pairs for quantitative analysis were as follows:m/z 313.29→256.25 (olanzapine),m/z 411.42→191.19 (ris peridone),m/z 427.45→207.18 (paliperidone) and m/z 386.43→122.37 (internal standard).RESULTS:The linear ranges of olanzapine,risperidone and paliperidone were 0.426-108.954,0.213-54.476,0.213-54.476 ng/mL,respectively.RSDs of inter-day and intra-day were all lower than 20%.The recoveries of them ranged 83.3%-112.9%,90.0%-109.8% and 95.2%-114.9%,respective ly.Extraction recoveries ranged 65.5%-95.0%,73.9%-98.5% and 73.6%-99.4%,respectively.Both plasma matrix effect and dilute effect didn't influence the determination of plasma concentration.The plasma concentrations of olanzapine,risperidone and paliperidone in 100 schizophrenia patients were (103.3 ± 73.6),(13.1 ± 13.1) and (23.2 ± 20.0) ng/mL,respectively.CONCLU SIONS:The method is simple,rapid,sensitive and specific.It can be used for the determination of plasma concentration and pharmacodynamic study of olanzapine,risperidone and paliperidone.

Objective A retrospective analysis were conducted to identify the effect of bypassing the emergency department on 30-days outcomes of patients with acute myocardial infarction undergone primary percutaneous coronary intervention ( PPCI) . Methods From June 2014 to April 2015, 187 patients underwent PPCI in Kunming General Hospital were included. 13 patients were excluded owing to their incomplete follow-up data. The total 174 patients were divided into two groups: the control group (n =59) who did not bypass the emergency department, and the bypass group ( n = 115) who bypassed the emergency department and directly received PPCI. The data of all patients were collected and analyzed. Results There were no significant differences in baseline characteristics and PPCI related data (including percentage of thrombus aspiration catheter used, length or diameter of stents applied between two groups (all P ﹥ 0. 05) . The bypass group had shorter door-to-ballon ( D2B) than the control group [ (67. 7 ± 21. 5) min vs. (89. 4 ± 23. 6) min, P ﹤ 0. 001] . There were no significant differences in 30-days all-cause mortality, re-myocardial infacrtion and target ressel revascularization (TVR) between the two groups (P ﹥ 0. 05) . Total MACEs rate in the bypass group was lower than in the control group (10. 2% vs. 1. 7% , P = 0. 012) . Logistic regression analysis showed that age, diabetes, pain-to-door (PTD) time and CK peak value were the main influencing factors for 30-day MACEs rate of patients receiving PPCI ( P ﹤0. 05) . Conclusions Bypassing the emergency department can shorten D2B time and reduce 30-days MACEs post-PPCI, but reducing the total ischemic time will be more beneficial to patients with acute myocardial infarction.

Objective:To investigate the application of Xingnaojing injection ( XNJI) in the patients of neurosurgery department to provide reference for the rational drug use. Methods:The retrospective investigation was applied to survey 200 hospitalization records with XNJI from a certain hospital between January 2014 and June 2015. The usage, dosage, medication purpose, course of treatment, compatibility and adverse effects of XNJI were analyzed. Results:The unlabeled use of XNJI was found in neurosurgery department, and 34. 50% of the surveyed patients were found that their diagnoses didn’t conform to the indications in the medicine specification of XNJI. Moreover, 92. 50% of the inpatients were treated with overdose and almost 90. 00% were treated with single drug dose of 40 ml. It was also found that XNJI was often combined with potassium chloride or with potassium chloride plus insulin in clinical use. Conclu-sion:There is some irrational use of XNJI in clinics, thus the use and management of traditional Chinese medicine injections should be strengthened and regulated.

BACKGROUND: Myelin sheath related inhibitors have been found to have great impact on microenvironment of axon regeneration. Traditional Chinese medicine is gradual y becoming a research hotspot on improving microenvironment of nerve regeneration with its advantage on multiple factors and targets.
OBJECTIVE: To clarify the effect of Jisuikang on Nogo-66 receptor NgR expression after spinal cord injury.
METHODS: 144 rats were randomly divided into six groups: sham surgery group, model group, prednisone group, high-, moderate- and low-dose Jisuikang groups (n=24). Animal models of spinal cord injury were established by the modified Allen’s method in the later five groups. Rats in the prednisone group were daily given 0.06 g/kg prednisone acetate by lavage, once a day. Rats in the high-, moderate- and low-dose Jisuikang groups were daily intragastrically given 12.5, 25 and 50 g/kg Jisuikang, once a day. Rats in the sham surgery and model groups were intragastrically daily given 20 mL of saline, once a day. Rats in each group were administered drugs until death.
RESULTS AND CONCLUSION: Compared with the model group, NgR protein and mRNA expression levels were significantly lower in the prednisone, moderate-and low-dose Jisuikang groups. These data suggested that Jisuikang can improve the recovery of neurological function after spinal cord injury and effectively inhibit NgR protein expression at the site of injury so as to suppress the microenvironment factors harmful to nerve regeneration and further improve the microenvironment of nerve regeneration.
