In view of the present situation of medical English vocabulary teaching, we propose to apply the picture teaching method to the teaching of English vocabulary. Picture application process is:teaching ideas - picture searching - picture introduction - question design - example sentence (implica-tions) introduction. We also analyze how to apply pictures related to Chinese and western culture, anecdotes and oddities, stars and celebrities, and common diseases to medical English vocabulary teaching according to the features and interest of the students, so as to activate the knowledge the students already acquired, to achieve good teaching effect through interaction between the teacher and students and to help the students have a solid command of medical English vocabulary taught in class.

Objective To certify whether 99mTc-HL91 can be trapped in ischemic myocardium prominently for clinical imaging. Methods The model of myocardial ischemia in rabbits was prepared and the distribution of 99mTc-HL91 was observed. The distribution of 99mTc-HL91 in the whole body was also observed. Results The myocardium of the left ventricle supplied by LCX was ischemic according to the change of electrical physiology and the results of NBT dying. The radioactivity in the myocardium of left ventricle supplied by LCX was higher than that supplied by LAD. LCX/LAD: 120 min, 2.57; 180 min, 3.45. 99mTc-HL91 was mostly distributed in the liver and kidney, next, the stomach and intestine. It was excreted through urination and defecation. There was little radioactivity in the heart and lungs and it eliminated quickly. 99mTc-HL91 was eliminated quickly from blood, too. Conclusion Ischemic myocardium can trap 99mTc-HL91 more significantly and relatively prominently at 180 minutes of post-injection. 99mTc-HL91 can be used in myocardial hypoxia imaging.

Objective To study common Gram negative bacterial pathogens and their drug resistant pattern in sputum isolates from patients in pediatric intensive care unit (PICU) of Chengdu children' s hospital. Methods Comparing to the period of 2004-2006 with 2007-2009, we retrospectively reviewed eligible sputum isolates of common Gram negative bacilli and their drug resistance pattern. All specimens were processed according to standard microbiological methods for both quantitative and qualitative cultures. Pathogen was the single predominant growth after two consecutive cultures. Strict quality control was used in all test agents and paper disk for drug resistance analysis. Results Total of 598 Gram negative bacterial isolates were identified in patients over 6 years. The first 5 bacteria respectively were Escherichia coli 167 samples(27.93%), Klebsiella pneumoniae 109 samples ( 18.23% ), Enterobacter cloacae 93 samples ( 15.55% ),Acinetobacter baumannii 64 samples ( 10. 7% ), Pseudomonas aeroginosa 43 samples (7. 19% ). They were mostly sensitive to Imipenam, Amikacin, Piperacillin/Tazobactam. Most drug resistance rate was found in Amoxicillin, Ampicillin, Cephalosporin. Apart from Pseudomonas aeroginosa and Acinetobacter Baumannii,no Gram negative bacteria was found to be resistant to Imipenam. Klebsiella pneumoniae and ESBL secreting Escherichia coli isolates were obviously increasing when compared to 3 years ago. Conclusion Comparing the period of 2004-2006, the Gram negative bacterial isolates were increasing in our PICU patients during 2007 to 2009. Close monitoring of drug resistance pattern changes in PICU would guide rational use of antibiotics in these critically ill children.

Objective To investigate the application value of transcranial Doppler ultrasonography(TCD) in critically ill children with cerebral dysfunction.Methods We detected the cerebral blood flow parameters[systolic velocity(Vs),mean velocity(Vm),end of diastolic velocity(Vd),pulsatility index(PI),resistance index(RI)] of middle cerebral artery in cerebral dysfunction group(n=20) and control group(no cerebral dysfunction,n=20),and observed the differences of those parameters between two groups.Children in cerebral dysfunction group were also divided into groups according to Glasgow Coma Score(GCS) and prognosis.The differences of each TCD parameter in diverse groups divided by GCS and by prognosis were analysed.Children in cerebral dysfunction group were checked TCD everyday until TCD parameters were normal.The relation between the days of TCD parameters′ reaching normal and GCS,duration of disorder of consciousness with correlation analysis were analysed.Results Vs,PI,RI in cerebral dysfunction group were higher than those in control group,while Vd was lower (P<0.05).(2)PI in the group of GCS less than 6 points(0.91±0.21) was higher than that in group of GCS 7-13 points(0.83±0.14)(P<0.05).The other parameters between two groups of GCS less than 6 points and GCS 7-13 points were not significantly indistinctive.Between the good prognosis group and the bad prognosis group,there were no significant differences in all parameters.(3) The days of TCD parameters′ reaching normal were negatively correlated with GCS(r=-0.653,P<0.01),but positively correlated with the duration of disorder of consciousness(r=0.923,P<0.01).Conclusion The cerebral hemodynamics of children with cerebral dysfunction is abnormal,the more serious cerebral dysfunction,the higher PI and the longer time for regaining normal TCD parameters.Constantly monitoring TCD could reflect the changes of cerebral hemodynamics and is valuable to assess the state of illness and prognosis.

Objective To screen for genomic copy number variants(CNVs)in six neonates with Pierre Robin sequence(PRS)by Affymetrix 2.7 M chip to identify possible loci related to PRS.Methods Six neonates with PRS admitted into the Department of Neonatology,Children's Hospital of Fudan University from June 2009 to May 2010 were enrolled in this study.CNVs were detected by Cytogenetic Whole Genome 2.7 M array.Rare CNVs with potential clinical significance that deletion segments' size ＞50 kb and duplication segments' size ＞200 kb were selected based on the analysis of Chromosome Analysis Suite(ChAS)software,false positive CNVs and segments of normal population were excluded.The identified CNVs were compared with those in relative published literatures.Results(1)Among 6 PRS patients,two patients had facial deformation,two had congenital heart defects,one had congenital dysplasia of the laryngeal cartilage and one had choroidal space occupying lesion.(2)Seven rare CNVs whose size from 51-11 956 kb were identified in four neonates,including a 739 kb duplication on lp26.23-p36.22,a 6273 kb deletion on lq43-44,a 51 kb and a 55 kb deletions on 14q32.31,a 1022 kb duplication on 14q11.1-11.2,a 11 956 kb duplication on 20p13 and a 105 kb deletion on 4q23.3.(3)Published literatures showed that deletions of 1q43-44 and 14q32.31 might relate to micro/retrognathia and abnormal palate.Region of chromosome 1q43-q44 contained AKT3 and heterogeneous nuclear ribonucleoprotein U(hnRNPU)genes,and the haploinsufficiency of AKT3 and hnRNPU genes might cause developmental human microcephaly and agenesis of the corpus callosum,speech delay and seizures respectively.Region of chromosome 14q32.31 contained some C/D small nucleolar RNA,and the human imprinted 14q32 domain shared common genomic features with the imprinted 15q11-q13 loci.Conclusions This study established a method to discover whole genome CNVs in identifying novel submicroscopic deletions and duplications.Reviewing of published literatures suggested that deletions of chromosome 1q43-q44 and 14q32.31 might cause Pierre Robin sequence.

Objective To explore the expression of urothelial carcinoma-associated 1 ( UCA1 ) in pancreatic cancer cell lines and its influence on the invasion and metastasis of the pancreatic cancer cells .Methods The expression of UCA1 in pancreatic cancer tissues and paired adjacent normal tissues ( 11 cases ) and 5 pancreatic cancer cell lines was analyzed by real-time PCR.The level of UCA1 in BxPC-3 was knocked down by small interfering RNA . The ability of invasion and migration in vitro of transfected BxPC-3 was detected by Transwell invasion assay and wound healing assay .The protein levels of MMP-2 and MMP-9 were measured by Western blot experiment .Results The expression level of UCA1 in pancreatic cancer tissues was higher than that in paired adjacent normal tissues , and UCA1 differentially expressed in 5 pancreatic cancer cell lines .Down-regulation of UCA1 by siRNA suppressed the expression of MMP-2 and MMP-9 in BxPC3, and dramatically impaired the ability of invasion and migration of BxPC-3.Conclusions UCA1 is over-expressed in pancreatic cancer , and down-regulation of UCA1 attenuates the capacity of invasion and metastasis in vitro of BxPC-3 by decreasing MMP-2 and MMP-9.

Objective To investigate the effect of miR-200 a mimic on transforming growth factor β1-mediated acti-vation and collagen secretion of rat pancreatic stellate cells .Methods PSCs were isolated and cultured from pan-creatic tissue and identified by desmin , GFAP and α-SMA immunofluorescence staining .PSCs of 2nd generation were divided into control group , TGF-β1 group, TGF-β1+miR-NC group and TGF-β1+miR-200a mimic group.α-SMA and collagen Ⅰ protein were measured by Western blot and immunofluorescence staining .The mRNA ofα-SMA and collagen Ⅰ and the expression of miR-200a were detected by quantitative real-time PCR.Results TGF-β1 stimulates the activation of PSCs and promote collagen synthesis in time-dependment manner ( P<0.05 ) . After transfection of the mimic , treating with the same concentration of TGF-β1, the expressions of protein and mR-NA of both α-SMA and collagen Ⅰ decreases significantly ( P<0.01 ) .Conclusions Over-expression of miR-200 a significantly attenuates α-SMA activity and further affects the collagen synthesis of TGF-β1-dependent activa-tion of PSCs.The mechanisms are potentially related to the biological effects of TGF-β1.

Objectives To evaluate final adult height(FAH), lipid profile, sexual development, and quality of life in individuals with childhood-onset growth hormone deficiency (CO-GHD) during the transition from childhood to adulthood, to reassess the function of GH-IGF-I axis, and to explore effective managements for different types of GHD in each period. Methods Totally 80 CO-GHD patients were divided into 2 groups; 22 patients with isolated growth hormone deficiency ( IGHD) and 58 patients with multiple pituitary hormone deficiencies (MPHD); 62 male (age ≥18 years) and 18 female ( age ≥ 16 years) patients. The clinical and biochemical parameters, education and occupation, rhGH, and other hormones therapy in the past were followed up. Results rhGH replacement improved FAH of patients with GHD. The incidences of either hyperlipidemia (39.0% , 47.4%) or fatty liver disease (26.8%, 31.6%) showed no statistically significant changes between 2 groups with and without rhGH replacement. Mean value of IGF-I SDS was significantly higher in IGHD group than that in MPHD group (-1.43±0. 31,-3. 01 ±0. 66) ,and also IGFBP3(-2. 10±0. 33,-3. 17±0. 19,all P< 0.05 ). Patients with IGHD had normal sexual development, but the incidence of sexual dysfunction accounted for 79.7% in MPHD group. Conclusions rhGH improves FAH of individuals with CO-GHD. Patients with CO-GHD should be followed during the transition period; GHD patients carry a high risk of metabolic abnormalities in the adulthood; IGHD female can give birth to offsprings; patients with MPHD have gonadotrophin deficiency of varying degrees.

Objective To understand the cleaning quality of dental handpieces in Suzhou City, analyze the relevant factors that influencing cleaning effect.Methods A cross-sectional study was performed with the proportional system sampling method, questionnaires were adopted to investigate the cleaning location, cleaning method and process of dental handpieces, the ATP fluorescence detection method was conducted to detect cleaning quality.Results In 10 administrative regions of this city, a total of 72 medical institutions were selected, 25 were public medical oral diagnosis and treatment institutions, 47 were private clinics.Cleaning effect of automatic handpiece cleaning machine was better than traditional manual cleaning (unqualified rate :3.95% vs 11.96%, P<0.05), unqualified rate of handpieces cleaned by cleaning personnel without inadequate knowledge was higher than that by personnel with adequate knowledge(14.88% vs 3.57%, P<0.05).Qualified rate of cleaning: different cleaning locations ranged from 5.00% to 11.23%, cleaning equipment was inadequate and sufficient 11.89% and 7.29% respectively, cleaning personnel were not designated and designated 12.16% and 9.83% respectively, but the difference were not statistically significant (all P>0.05).The quality of cleaning of handpieces could be improved if waiting time of cleaning ≤30 minutes, enzymes were used during cleaning, and purified water was used at the end rinse(all P<0.05);whether there was drying process and used lubricant, difference were both not significant.Conclusion Using automatic handpiece cleaning machine, cleaning personnel with adequate knowledge, cleaning waiting time ≤30 minutes, enzyme use during the cleaning process, and purified water use at the end rinse can improve the quality of cleaning of dental handpieces.
