Chinese Journal of Medical Education Research 2015;(3):293-297
Objective To investigate whether the effect of PBL is better than LBL when used in a new type of three phases labor trainee teaching. Methods 216 medical students of the five-year and seven-year program who took part in labor trainee in the 2013-2014 school year were chosen and divided into two groups:PBL group and LBL group. Both the two groups' labor trainee were performed as three phases: trainee preparation, delivery room trainee, and discussion-class after trainee. Ques-tionnaire investigations were used to evaluate the effect of the delivery room trainee and discussion-class in PBL group and LBL group. A quiz after the third phase was used to examine whether the teaching effect of the two groups is different or not. Statistical analysis was performed using SPSS 16.0 software. Count data between sample rates were compared by chi square test, mean data between the two groups were compared by t test, the inspection level is α=0.05. Results Both in the delivery room trainee and discussion-class after trainee, questionnaire score in PBL group was significantly higher than that in LBL group (P<0.05). The average of quiz score in PBL group was 25.7±2.1, which was significantly higher than that in LBL group (19.3±3.6) (P<0.05). The excellent rate in PBL group was 82.6%, which was also higher than that in LBL group (P<0.05). Conclusion PBL teaching method elevates learning initiative of medical students and increases the teaching effect, and it can be promoted in labor trainee teaching.

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.

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 study the quality control methods for dragon's blood spraying film agent. Methods The pH value and viscosity of dragon's blood spraying film agent were detected. Drug dispersed homogeneous degree and particle sizes were determined with Nano Particle Size Analyzer and microscope. Content of Loureirin B was measured by Ultra Performance Liquid-Chromtography (UPLC). UPLC was performed on Waters C18 column (2. 1 mm×100 mm,1. 7 μm), the wavelength was 280 nm, the column temperature was 40 ℃ , and the mobile phase was 0. 1% formic acid aqueous solution and acetonitrile, and the flow rate was 0. 8 mL·min-1 . Results The pH value and viscosity of dragon's blood spraying film agent were stable, drug dispersion was homogeneous, and particle size of the drug was tiny. The concentration of Loureirin B had a good linear relationship in the range of 15. 51-77. 54 μg. Conclusion This method can be accurately controlled, has good stability and repeatability, and can fully control quality of dragon's blood spraying film agent.

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.
