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.

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.

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.

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.

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.

To optimize bacteriocin production,researching was done on the respect of incubation condition and the media components. And the optimum incubation time was 24h, the optimum temperature was 30℃, the optimum broth initial pH was 6.5. The optimum media component was: lactose 30g, trypone 15g, soybean peptone 20g, meat extract 30g, peptonethe 20g, Tween 80 1mL, K_(2)HPO_(4 )2g, NaAc 5g, Tri-Ammonium citrate 2g, (MgSO_(4)) 0.58g, MnSO_(4) 0.25g, H_(2)O 1000mL. Production of bactericoin under the optimum broth was 640AU/mL, 8 times than MRS media.

Objective To investigate the effect of fluoride on expression of Runx2 mRNA and protein in bone tissue of rats. Methods Fourteen SD rats were randomly divided into two groups: control group(tap water with fluoride ＜ 0.06 mg/L), and fluorosis group(fluoride 50 mg/L in water). After 4 moths, expressions of both mRNA and protein of Runx2 in rat bone tissue were determined by RT-PCR and Western blotting. Results The results showed that the expression of Runx2 mRNA and protein in fluoride-treated bone tissue were 2.287 ± 0.261 and 0.929 ± 0.229, respectively, both of which were significantly higher than those of control group(0.995 ± 0.123,0.317 ± 0.068, t = 11.85,6.78, P ＜ 0.05). Conclusions Fluoride can increase the expression of Runx2 mRNA and protein in bone tissue of rats, and Runx2 may be involved in the pathogenesis of bone injury caused by fluoride.

Objective To establish a method for determination of total hardness in drinking water by using automatic potentiometric titrator.Methods Dynamic equivalence point titration(DET)and monotonic equivalence point titration(MET)mode was used to determine the high total hardness and low total hardness of drinking water samples respectively.Results Used DET mode to determine the high total hardness,the relative standard deviation(RSD)was 0.69%～1.72% and the recovery rate was 101.5%～102.2%.Used MET mode to determine the low total hardness,RSD was 3.49%～4.00% and the recovery rate was 95.8%- 103.6%.Conclusion This method is rapid,simple,accurate,precise and applicable to the determination of total hardness in drinking water in low and high levels.

Objective In this study, we tested the ability of platelet-rich plasma to enhance bone consolidation during distraction osteogenesis in a rabbit model of leg lengthening. Methods Twenty New Zealand white rabbits, which were randomly divided into two groups, the PRP treated group and the control group (n=10). Osteotomy will be made under the tibiofibular junction of left tibia, and 1cm tibia shaft will be removed through a second osteotomy. The tibia will be shorted for 1cm and then fixed by Orthfix unilateral lengthener with 4 pins. Lengthening will start 7 days after the osteotomy surgery, at a rate of 1.0 mm/day, in two steps, for 10 days. 500ul PRP were respectively injected into the distraction gaps at the end of the 10-day lengthening and at 10 days before termination. No management in the control group. The animals were terminated at day 20 following final lengthening. Serial radiographs will be taken at the day of surgery, day 12, day 17, day 27, day 37, using a C-arm radiography system. The excised bone specimens were scanned by X-ray and Micro-CT, and the bone mineral content(BMC) and the bone mineral density(BMD) of the regenerates were calculated and compared. Results The regenerate of PRP treated group was significantly better than the control group. The X-ray figures showed that the regenerate was significantly more than the control group. The figures of micro-CT 3D reconstruction showed that the growth and remodel of the regenerate in PRP treated group was better than the control group. Micro-CT examination of regenerates demonstrated a significantly greater bone mineral content(BMC) and the bone mineral density(BMD) in the PRP treated group compared to the control group(P
