Objective:To explore the characteristic of parenting style and its relationship with self congruence in Tibet middle school students.Methods:Totally 1149 Tibet students in 2 middle schools were investigated by the Scale of EMBU (Egma Minnen av Bardndosnauppforstran)and SCCS (Self Consistency and Congruence Scale) from counties resided mainly by Tibet people.Results:The total average scores of Tibet students'self-congruence were lower than the median[(2.8 ± 0.3) < median 3].There was no significant difference between genders [(2.6 ±0.3)vs.(2.7 ±0.4),P >0.05],and the scores of self flexibility had statistical significant difference in gender [(2.9 ±0.5)vs.(2.8 ±0.5),P <0.05].The scores of parenting style in positive elements were negatively correlated with self congruence in Tibet middle school students (r =-0.20,P <0.01 ).Multi-linear regression showed that the element of maternal emotion and understanding had negative relevance with SCCS(β=-0.16,P <0.01),while the element of maternal rejection and denial had positive relevance with SCCS(β=0.16,P <0.01) .Conclusion:It indicates that the level of self-congruence is higher than median,and that parenting style might have a certain relationship with self congruence in Tibet middle school students.

According to content of ‘lipid metabolism’,we crafted a effective case for problem based learning (PBL) and practiced it in biochemistry course.In group discussion,students participated in discussion with great enthusiasm and initiative.During the discussion,students got a better understanding about lipid metabolism and clinical application of the knowledge.As teachers,we maily guided students during PBL,and at the same time,we also summed up the experience and explored how PBL be implemented for freshmen and sophomores who lack clinical practice.

Objective:To investigate the model,quality as well as effect of teaching-in-English in five-year clinical medicine program of Hainan Medical University.Methods:The questionnaire was carried out among clinical medicine undergraduates of 2012-2015 grades in Hainan Medical University,to investigate studying time,studying habits and the impact of teaching in English.Additionally results of CET-4,CET-6 and overseas internship from undergraduates of 2012-2015 grade,as well as the result of phased medical licensing examination and post-graduate entrance examination from undergraduates of 2012 were accordingly collected from the Teaching Management Department.Results:For the Chinese students in international classes,the average time of self-study was 161.49 min,58.3％ had preview before classes,and 90.7％ had habit of review after classes.Thus the first time pass rate,total pass rate,first time excellent rate and total excellent rate of CET-4 and CET-6 of international classes were significantly higher than those of regular classes.The result of post-graduate entrance examination in 2016 showed that the score,pass rate and acceptance rate of international classes of 2012 grade were significantly higher those of regular classes (P ＜ 0.01).Conclusions:Teaching-in-English reform in Hainan Medical University has achieved initial success.Chinese students from international classes are superior to those from regular classes in many aspects.However,there are still many problems,and effective measures should be implemented to promote teaching quality continuously.

Objective: To summarize the different cardiac shunt presentation in right heart contrast echocardiography and to clarify its clinical value for diagnosing the patients with congenital heart disease (CHD).
Methods: We retrospectively analyzed 102 patients who received right heart contrast echocardiography in our hospital from 2006 to 2014. The contrast media was the hand-vibrated mixture of 9 ml 50% glucose solution with 1 ml air.
Results: There were 49/102 patients with abnormal blood shunt detected including 8 patients of atrial septal defect (ASD) with right to left or dual shunt, 7 of ASD with left to right shunt, 9 of patent foramen ovale (PFO) with functional right to left shunt, 13 of patent ductus arteriosus (PDA) combining pulmonary arterial hypertension, 3 of pulmonary arteriovenous ifstula (PAVF), 9 patients with persistent left superior vena cava (PLSVC) and 8 of them drain to coronary vein sinus, 1 drain to left atrium.
Conclusion: Right heart contrast echocardiography may simply and effectively detect abnormal blood shunt in patients combining pulmonary arterial hypertension and improve the diagnostic accuracy of CHD.

Objective To analyze the relationship between the change of serum vascular epidermis growth factor(VEGF) level and curative effect of pancreatic cancer treated by gamma rays, and evaluate it clinical significance. Methods The serum VEGF level of thirty patients with pancreatic cancer treated by gamma rays were determined before and one month after treatment. The relationship between curative effect,survival, life quality and the serum VEGF level was analyzed. Results The serum VEGF level of 30 cases before treatment was (624.1 ± 144.3) pg/ml, whereas one month after treatment it was (279.3 ± 83.4) pg/ml(P ＜0.01 ). In the 19 patient whose serum VEGF level decreased by more than 50%, CR + PR was gained in 18 patients, improved quality of life in 7 patients, and in the 11 patient whose serum VEGF level decreased by less than 50%, CR + PR in 7 patients, improved quality of life in 1 patient( P = 0.012, P = 0. 028). In 24patients who completed 2 years follow-up, 11 of 15 patients whose serum VEGF level decreased by more than 50% survived more than 1 year, which was higher than that of the patients whose serum VEGF level decreased by less than 50%. Conclusions The serum VEGF level decreased significantly after gamma rays treatment and the extent of decrease could be used as a surrogate to evaluate the therapeutic efficacy.
