Objective To investigate the effect of case simulation and participatory feedback teaching used for neonatal resuscitation training. Methods One hundred and twenty medical staff was selected as subjects from Obstetric and Pediatric department and were randomized into 4 batches to receive a neonatal resuscitation training program that consisted of theoretical lectures and skill practice. In the control group (first two batches), the teacher demonstrated procedures of neonatal resuscitation, then trainees practiced alone and the teacher corrected their wrong procedure. In the observation group (last two batches), interactive teaching was employed and the training was performed into three steps:practice of skill in teams, watch the procedure of their practice, the feedback. The theoretical exami-nation score, practical examination score, teamwork ability and satisfaction were compared between two groups. SPSS 16.0 was employed for statistical analysis, with α=0.05 as detection level. Results The theoretical examination scores of control group and observation group were (34.27 ±2.26) vs. (33.68±2.32). There was no significant difference in theoretical examination score between the two groups ( P=0 . 166 ) . The practice examination score s of control group and observation group were (36.15±1.46) vs. (34.79±2.43), with significant differences (P=0.000). The teamwork ability of control group and observation group were (35.78 ±1.26) vs. (33.63 ±1.98), with obviously significant differ-ences (P=0.000). The trainees individual study interest, practice intent, knowledge and satisfaction with the training in the observation group were significantly higher than the control group. These results were (8.45±2.75) vs. (6.24±2.28), P=0.001;(8.25±2.05) vs. (6.48±2.75), P=0.003;(7.23±1.37) vs. (5.75 ±1.74), P=0.000; (8.21 ±1.45) vs. (6.34 ±1.69), P=0.000. Conclusion Application of the teaching in neonatal resuscitation training can enhance comprehensive practical skills and team coop-eration ability in med-ical staff, and it improves trainee's satisfaction with the training.

Objective:To observe the localization of chicken infectious anemia virus VP3 gene in normal cells and breast cancer cells in different times and its apoptosis-inducing effect.Methods: The fundamental cloning method,inserting the VP3 gene of chicken anemia virus into the eukaryotic expression vector pEGFP-C1 was used.Then,the positive recombinant containing VP3 gene pEGFP-C1-VP3 was transfected into human breast cancer cell line MCF-7 and mouse fibroblasts L929 by FuGENE(R)6 transfection reagent in vitro respectively.After 24 hours,48 hours and 72 hours,fluorescence microscope was used to observe the distribution of VP3 in cells and the rate of apoptosis was studied on the treated MCF-7 cells by FCM(Flow Cytometry).Results: The recombinant plasmid pEGFP-C1-VP3 could be localized in the nuclei of breast cancer cells,which showed the typical nuclear changes in different stages of apoptosis.In L929 cells,pEGFP-C1-VP3 underwent a process of migration from the nucleus to the cytoplasm,which didn′t induce apoptosis of L929 cells.Conclusion: VP3 located in the nucleus of MCF-7 breast cancer cells,which can led to cancer cell death by inducing apoptosis,and the apoptosis rate was higher than the control group with time dependence.VP3 located in the cytoplasm of normal cells,and didn′t induce apoptosis.

22q11.2 deletion syndrome (22q11.2DS) is the second leading chromosomal cause of congenital heart disease (CHD) after Down syndrome.In the past few decades, great progress has been made in describing the anatomical types, potential heredity, and pathogenesis of CHD complicated with 22q11.2DS in terms of improving the diagnosis and treatment of these diseases.However, cardiac malformation is still the leading cause of death in 22q11.2 DS.Further studies are needed to elucidate the genetic mechanism behind high phenotypic variability of CHD and to explore the multidisciplinary treatment for the improvement of the prognosis.22q11.2 gene detection in patients suffering from CHD may provide useful insights into early diagnosis and multidisciplinary treatment.

Objective To investigate the relationship between aquaporin-4 (AQP4) expression level inbrain and dynamic change of brain edema in rats after cardiopulmonary resuscitation (CPR), and to evaluate the in-tervention effects of Edaravone. Method Totally 72 Sprague-Dawley male rats were randomly divided into fourgroups:normal group (n = 6, group A) ,shame-operated group ( n = 6, group B), CPR group including 1 hour,6 hours, 12 hours, 24 hours, and 72 hours after ROSC (5 sub-groups, n = 6for each,group C) ,edaravone-treat-ed group with the same time points as CPR groups(5 sub-groups, n = 6for each,group D). Asphyxia cardiac ar-rest with CPR model was used in group C and group D. Edaravone at a dose of 3.0 mg/kg was given intravenouslyand the same dose of edaravone was administered subcutaneously to the rats of group D after CPR. Anaesthosia,vascular cannulation and endotracheal intubation were pedormed in rats without asphyxia and CPR in group B. Ateach interval, the brain water content was calculated. The AQP4 expression level in brain tissue was determinedusing immunohistocbemical staining. Neurodeficit scores were assessed and pathological change was observed, Re-sults The brain water content in rats of group C increased obviously along with the prolongation of time followingROSC,and reached its peak at ROSC 24h,which was much higher than that of group B (P<0.01). Meanwhile,AQP4 expression in brain had a trend towards increasing and the integral optical density(iOD) and coloratian arearatio(△S) in group C were significantly increased compared with group B ( P<0.01). The trend of changes wasnearly the same as that of the brain water content. The correlation analysis demonstrated that AQP4 expression levelsuch as iOD (r=0.858, P < 0.01 ) and △S ( r = 0.870, P < 0.01 ) were correlated with the brain watercontents apparently. Compared with group C, the brain water content was decreased obviously (P<0.05), iODand △S was down-regulated at the same lime (P<0.01) in group D. The neurodeficit scores increased (P <0.05) and pathological damage was dramatieaUy ameliorated. Conclusions AQP4 expression increased greatly inbrain after CPR and the relationship between AQP4 and brain edema was positively correlated. AQP4 may play arole in the formation of brain edema following CPR. Edaravone could attenuated brain edema after CPR in rats byway of inhibiting the expression of AQP4. It had neuroprotective effect.

Objective SELDI-TOF-MS technology was used to contrastly analyse the changes of protein expression profiles of gastric cancer cells after TGF-?1 stimulation,and provide theoretical and experimental foundation for screening different significant proteins. Methods Serial subcultivation gastric cancer cells BGC823,MKN45,and SGC7901 cultured in vitro were grouped into test and control groups.TGF-?1 was added to the test group,but not to control group.Cell culture fluid was collected and centrifuged after cultured 24h,and crossing with WCX2 protein chip to detect protein differences. Results When the test group was compared with control group,we found:(1) thirteen different proteins in BGC823 cells after TGF-?1 stimulaton,and their M/Z were M4294,M4932,M4945,M4972,M4991,M5015,5036,M5060,M5153,M5180,M5197,M8577,and M8784,respectively;(2) eighteen different proteins in MKN45 cells after TGF-?1 stimulaton,and their M/Z were M4292,M4931,M4945,M4972,M4990,M5014,M5152,M5178,M7055,M8190,M8570,M8652,M8670,M8780,M9963,M10098,M10523,and M11653,respectively;(3) eight difference proteins in SGC7901 cells after TGF-?1 stimulation,and their M/Z were M4945,M4972,M4992,M5015,M5180,M7056,M8573,and M8604,respectively. By comparing three protein expression profiles of gastric cancer cells after TGF-?1 treatment,we found two significcant proteins with common differences,that had M/Z of M4945 and M4972,respectively. Conclusions The biological markers whose M/Z is M4945,M4972 with gastric cancer characteristic and associated with TGF-?1 have been screened,which can be as the basis for early prediction and clinical diagnosis research on metastasis and invasiveness of gastric cancer.
