Aimed at problems in current audio-visual-oral English teaching for medical students,such as the inconsistency between teaching materials and training objectives,the lack of flexibility and effectiveness in teaching methods and inadequacy of comprehensiveness and objectiveness in assessment methods,the paper analyses and explores audio-visual-oral medical English teaching in three aspects,namely teaching curriculum-setting up topic for each unit based on the contents of medical courses and designing various teaching tasks according to three-step procedure of extensive listening-intensive listening-derivative discussion,teaching methods-adopting pictorial method in teaching medical English vocabulary,macro-micro listening method and interpretation for imitation method,and assessment methods-applying a combination of formative assessment and summative assessment.

This paper presents a preparation method and quality control standards of Hungqiduotang Granules. Meanwhile, the experiment result of primary studys on its preparation stability shows that the process and prescription is simple and reasonale, and the stability of granules is good.

There has been great progress in seizure control with the development of antiepileptic drugs,but 30％ of epileptic children are refractory to antiepileptic drugs.In order to control intractable epilepsy and improve neurodevelopment prognosis,the non-drug therapy such as surgery,vagus nerve stimulation and ketogenic diet (KD) can be taken.Despite its indisputable effectiveness,the functioning of the KD has not been explained.Now the antiepileptic mechanism and neuroprotective mechanisms are studied mainly.It is reported that KD is effective in variety of refractory epilepsy,and recent studies have shown that KD promising in the treatment of children with autism.Although KD is effective,it is worth further study that including its mechanism,recipe,clinical application,and so on.

The content, range, mode and method of medical equipment management were explained by associating hospi- tal actuality. The value of scientific management can be directed and improved economic benefit and social effect too, which are an important construction of hospital efficiency.

Object To optimize the best technical parameters through controlling the different factors. Methods Taking spherical degree and pill weight as index, the above factors were observed by orthogonal test. Results PEG4000 as matrix, methyl silicon oil as refrigerant. Internal and external diameter of burette are 4 1 mm and 6 1 mm, dropping into the refrigerant that composed of 40 ℃—50 ℃,10 ℃—30 ℃,0 ℃—4 ℃ by 20 ℃—30 ℃ droppings per minute. Conclusion The highest finished product with good quality can be got through this process.

Objective To explore the intervention effect of cathepsin B inhibitor (CBI) and its signaling pathways after flurothyl inducing brain injury in rats with recurrent seizures. Methods 6-day-old (P6) SD rats were randomly divided into: recurrent neonatal seizure group ( RS group, n = 30), CBI-treated seizure group ( CBI group, n=30) and the control group( CONT group). Rats in RS group were subjected to 5 seizures with flurothyl during the first 14 days of life. In CBI group,CBI was injected each day before seizures were induced. Then examined development indexes such as the physical growth, neural reflex, neural behavior and cognitive emotional competence. Western blot was employed to determine Cathepsin B expression at different time points ( 1.5h,3h,6h,24h and P35) after the last convulsion. Results The weights of rats in RS group( (27.28 ± 1.6) kg) were lighter than CONT group( ( 33.45 ± 1.57 ) kg). They had significant difference (P＜ 0.01 ) at the age of p14. The time of cliff avoidance in RS group( (2. 10 ± 1.45 ) s) was longer than CBI group( ( 1.05 ± 0. 32) s). It showed a statistically significant (P ＜ 0.05 ) in p12. In the open-field behavior test: the activities of RS group (20.00 ± 13.08 )were markedly reduced than CONT group ( 57.83 ± 33.22 ) in the horizontal movements, the RS group ( 2.50 ±2.43 ) were significantly decreased than the CONT group and CB1 group( ( 22.17 ± 10.74), (9.33 ± 5.39 ) ) in the vertical motions (P ＜ 0. 05 ). Cathepsin-B expression in RS group( 1.5h, 3h,6h and 24h )was significantly higher than that at the same time in CONT group(P＜ 0. 05 ). Cathepsin-B expression of CBI group was significantly decreased compared with that in RS group (P＜ 0. 05 ) at the time point (1.5h ,3h,6h and 24h). There were no significant differences among three groups at P35(P＞0.05 ). Conclusions CBI can improve brain injury and regulate the expression of abnormal molecules.

Objective To explore the dynamic expressions of autophagia and apoptosis associated protein Beclin-1, Cathepsin B and Bcl-2 in hippocampus and the intervention efficacy of cathepsin-B inhibitor (CBI) after recurrent neonatal seizure. Method Ninty 6-day-old SD rats were randomly (random number) divided into the recurrent neonatal seizure group (RS group, n = 30), CBI-treated seizure group (CBI group, n = 30) and the control group (n = 30). Rats in RS group were subjected to 55 attacks of seizure induced by using flurothyl during the consecutive 9 days beginning on the 6 th postnatal day (P6). In CBI group, CBI (2 μL, 0.5 μg/μL) was administered every day before seizures induced. Western blot was employed to determine the protein level at different intervals (1.5 h,3 h,6 h,24 h) after the last convulsion.Results There were higher expressions of Beclin-1 and Cathepsin B, and lower expressions of Bcl-2 expression in RS group(1. 5 h,3 h,6 h and 24 h) than those at the same time in control group (P ＜ 0.05). Beclin1 and Cathepsin B expressions were lower while Bcl-2 expressions were higher in CBI group at the intervals of 1.5 h,3 h,6 h and 24 h compared with those in RS group (P ＜ 0. 05). Conciusions Autophagic and apoptotic pathways were activated immediately after recurrent neonatal seizures as indicated by expression changes of Beclin-1, Cathepsin B and Bcl-2 in hippocampus, which suggests a synergistic effect of the two pathways in the pathophysiology of the long-term brain damage of neonateε resulted from the adverse effects of recurrent neonatal seizures.
