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.

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.

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 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.

[ ABSTRACT] AIM:To study the influence of insulin resistance on fatty liver in the mice fed with high-fat diet (HFD).METHODS:Male 8-week-old C57BL/6J mice were randomly divided into HFD group (with 60% calories by high saturated fatty acid) and control group (with chow diet).The mice in both groups were fed for 12 weeks.The body weight, liver weight, serum triglyceride (TG) and total cholesterol (TC), and blood glucose and insulin levels were meas-ured.Hyperinsulinemic euglycemic clamp experiment was applied to reflect insulin sensitivity .The lipid deposition in the liver was analyzed by HE staining , Sudan IV staining and measurement of liver fat content .The phosphorylation levels of IRS1 and Akt, and the protein levels of SREBP-1 and FAS were determined by Western blot to reflect the activities of insu-lin signaling and lipid synthesis .RESULTS:Compared with control group , the body weight and liver weight were signifi-cantly increased in HFD group .TG and TC contents in serum and liver tissues were remarkably increased in HFD group . High-fat diet induced insulin resistance , as evidenced by increased serum insulin levels , reduced glucose infusion rate and decreases in IRS1 and Akt phosphorylation levels .In livers of HFD group, HE staining showed that the cytoplasm of hepa-tocytes was filled with vacuoles .Sudan IV staining also displayed that many different sizes of red lipid drops existed in the hepatocytes , and the protein levels of SREBP-1 and FAS were significantly increased .In primary normal hepatocytes with exogenous oleic acid intervention for 48 h, the phosphorylation levels of IRS 1 and Akt were reduced , and the protein ex-pression of SREBP-1 and FAS was significantly increased in a dose-dependent manner .CONCLUSION: Feeding with HFD leads to insulin resistance , resulting in activation of lipid synthesis and accumulation of lipid deposition in the liver , thus inducing fatty liver .

Objective:To investigate the expressions and their clinical significance of vascular endothelial growth factor (VEGF) and extracellular matrix (ECM) components in non-small cell lung cancer (NSCLC). Methods:Expressions of VEGF and ECM components (fibronectin, FN and collagen Ⅳ, cⅣ) in 50 cases of NSCLC tissues and 20 cases of normal lung tissues were detected by immunohistological analysis. Their relationship with clinical features of NSCLC and the correlation of expression of VEGF and Fn and cⅣ were analyzed.Results:The positive expression rates of VEGF, Fn, and cⅣ were 96%, 78%, and 50% in NSCLC tissues. The expressions of VEGF and Fn were significantly higher than those in normal lung tissues (P<0.05). The expression of Fn and over-expression of VEGF were associated with lymph node metastasis (r=1.00, P<0.001). The survival rate of patients with over-expression of VEGF was greatly lower than that with weak expression of VEGF (P=0.022). The survival rate of Fn-negative patients was markedly higher than that of Fn-positive patients (P=0.046). Conclusion:VEGF and ECM component Fn were highly expressed in NSCLC, which correlated with lymph node metastasis and survival rate. Expression of ECM and VEGF had positive correlations, suggesting that ECM might be one of the anti-angiogenesis targets for tumor therapy.
