Objective: To study the effect of simulating scene method in teaching neurology.Method:Simulating scene method in teaching neurology of noviciate,the student and teacher joint evaluation and comparison with controlled group were applied.Results: According to students' evaluation,simulating scene method can improved students' leaning interest,clinical performing skill and clinical thinking,which had significant difference compared with that of controlled group.According to teachers'evaluation,simulating scene method could improve students'leaning attitude and elevate the clinical performing mark,which was also significantly different compared with controlled group.Conclusions:Simulating scene method can improved students' clinical performing skill and teaching effect.

Objective To develop a convenient, rapid and specific method using real-time fluorescent quantitative polymerase chain reaction (FQ-PCR) for detection of facioscapulohumeral muscular dystrophy(FSHD). Methods Genomic DNA was extracted and digested by restricted endonuclease EcoR Ⅰ , followed by agarose electrophoresis. The DNA (< 38 kb) was retrieved from agarose electrophoretic gels. The primers and probe were designed in D4ZA gene in chromosome 4. One hundred and fifteen subjects were examined by FQ-PCR using the retrieved DNA (<38 kb) as a template and the result was analyzed by fluorescent curve comparing with positive control. Results The results by FQ-PCR showed that 13 cases were positive in 16 FSHD cases whose EcoR Ⅰ fragment sizes were known, 75 cases were negative in 78 cases of normal controls, 15 cases were positive in 16 FSHD cases diagnosed clinically whose EcoR Ⅰ fragment sizes were unknown, and 3 cases were positive in 5 cases of relatives of FSHD patients. Consistency was checked using Kappa index between the 2 gene diagnostic tests for FSHD (FQ-PCR test and the traditional Southern blotting test), and between the 2 diagnostic criterions (gene diagnosis by FQ-PCR and clinical diagnosis). The results were statistically significant (κ = 0. 765, P = 0. 002 ; κ = 0. 844, P = 0. 000). Conclusions A new genetic diagnostic method of FSHD by FQ-PCR was developed, which was more simplified and reliable compared to the time-consuming, radioactive Southern blotting. It could also detect the D4Z4 arrays in cases having deletion of p13E-11 as well as the interchromosomal exchange between 4q35 and 10q26. The new method of FQ-PCR for FSHD may be extended to utilize clinically in future.

Objective To investigate the role of network platform for treatment and rescue of acute and severe cerebrovascular diseases in improving treatment level of patients with acute ischemic stroke.Methods The differences of number of patients accepted venous thrombolysis, number of patients accepted emergency intravascular interventional treatment, and time from admission to intravenous thrombolysis (door to needle time [DNT]) were analyzed in patients with acute ischemic stroke admitted to our hospital in the first year (2016) and the second and third years (2017 and 2018) of construction of network platform for treatment and rescue of acute and severe cerebrovascular diseases in Yunfu city. The National Institutes of Health Stroke Scale (NIHSS) scores were compared in 120 patients selected randomly from online referral (study group,n=60) and non-online referral (control group,n=60) within the same time periods in 2018.Results In 2017 and 2018, the number of patients accepted intravenous thrombolysis was 85 and 103, respectively, and the rate of intravenous thrombolysis was 9.92％ and 9.83％; they were all significantly larger/higher than those in 2016 (n=50, 6.97％,P<0.05). In 2017 and 2018, the number of patients accepted emergency endovascular treatment was 56 and 129, respectively, and the emergency endovascular treatment rate was 6.53％ and 12.31％; they were all higher than those in 2016 (n=44 and 6.14％), and the differences between those in 2018 and 2016 were statistically significant (P<0.05). The DNT ([82.00±18.75] min in 2017 and [77.00±32.17] min in 2018) was significantly shorter than that in 2016 ([109.00±30.58] min,P<0.05). The NIHSS scores of the study group and control group were 4.70±3.64 and 8.90±5.62, respectively, after one week of treatment, both of which were lower than those before treatment (14.30±6.29 and 13.60±6.37); and after treatment, the NIHSS scores of the treatment group were statistically lower than those of the control group (P<0.05). Conclusion Construction and effective operation of network platform for treatment and rescue of acute and severe cerebrovascular diseases is an effective guarantee to improve the success rate of treatment for patients with acute ischemic stroke.
