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.

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.

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.

Objective To investigate the effects of leptin on the oxidative damage in human retinal pigment epithelial (RPE) cells.Methods Human RPE cells (ARPE-19) were cultured in vitro,and randomly divided into control group and insulin resistance group.RPE cells were treated with 0,10,100 ng/mL leptin for 24,48,72 hours respectively.Then the levels of reactive oxygen species (ROS) expression in RPE cells were detected by 2',7'-dichlorofluorescin-diacetate (DCFH-DA),and the levels of 8-hydroxy-2′-deoxyguanosine (8-OHdG) expression in RPE cells were observed by immunocytochemistry (ICC),and the levels of human 8-oxoguanine DNA glycosylase 1 (hOGG1) expression in lysate were measured by Western blot.Results After 24,48,72 hours,the level of ROS (Control group:F=37.136,37.178,49.634; P＜0.05.Insulin resistance group:F=9.822,28.881,71.150;P＜0.05),8-OHdG (Control group:F =88.643,390.920,1039.276; P ＜ 0.05.Insulin resistance group:F =273.311,299.155,82.237;P＜0.05) and hOGGl (Control group:F=470.062,1073.113,295.456;P＜0.05.Insulin resistance group:F =240.032,592.389,527.760 ; P＜0.05) expression increased significantly with the increase of leptin concentration in control group and insulin resistance group.Under the same leptin concentration,the level of 8-OHdG has a trend that it was higher in the insulin resistance group than the control group.After 24 hours,the difference of hOGGl expression between control group and insulin resistance group was not significant (F=23.392,P＞0.05).After 72 hours,the level of hOGGl expression was significantly higher in the insulin resistance group than the control group (F=129.394,P＜0.05).The level of hOGGl expression was significantly higher at 48 hours than that at 24 hours and 72 hours (P＜ 0.05).Conclusion Leptin could induce the oxidative damage of RPE cells in normal and insulin resistance status.With the increase of leptin concentration and time extended,the degree of oxidative damage and its repair were both increased.The degree of oxidative repair increased with the increase of leptin concentration,but decreased with time extended.

OBJECTIVE:To investigate the pathogen distribution and drug resistance situation in bronchoalveolar lavage fluid (BALF) from patients with refractory pulmonary infection,and provide reference for clinical rational drug use. METHODS:The sputum and BALF specimen of 136 inpatients with refractory pulmonary infection from the First People’s Hospital of Zhenjiang City from Jan. 2012 to Dec. 2015 were cultured and identified,pathogen detection was compared,and results of drug sensitivity test for pathogen in BALF specimen was analyzed. RESULTS:The positive rates of sputum and BALF specimen of 136 inpatients were 22.06%and 47.79%,with statistical significance(P<0.01);a total of 32 and 72 strains were isolated,they mainly were Ste-notrophomonas maltophilia,Pseudomonas aeruginosa,Acinetobacter baumannii and Staphylococcus aureus. S. maltophilia in BALF was sensitive to minocycline and levofloxacin;resistance rate of P. aeruginosa to common antibiotics was lower than 50%;A. baumannii was sensitive to imipenem,ampicillin sodium and sulbactam sodium,amikacin and minocycline;S. aureus was sen-sitive to linezolid,chloramphenicol and vancomycin. CONCLUSIONS:The positive rate of BALF specimen is higher than spu-tum,the pathogens are mainly Gram-negative bacteria. Clinic should rationally select antibiotics based on the drug sensitivity test and clinical symptoms.

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

s Objective To explore the value of B mode ultrasound in the detection of amniotic fluid(AF) for fetus of 41～ 46 +6 gestation weeks.Methods B mode ultrasound was performed to monitor AF in 232 fetus of 41～46 +6 gestation weeks compared with that in 296 fetus of 37～40 +6 gestation weeks.
