In order to discuss the methods for the promotion of bilingual teaching in general medical college,we have carried out bilingual teaching of pathology for the undergraduate students of clinical medical department by exactly comprehending the meaning of “bilingual teaching”,training a troop of high-quality bilingual teachers,sensibly selecting and using the original edition of English teaching materials and bilingual assistant teaching materials,as well as experimenting feasible teaching means,the results are successful and the primary experience has been got.

Objective To investigate the value of pathological examination in the diag-nosis of lethal cases due to acute poisoning.Methods The macroscopic and microscopic find-ings in 28 autopsy cases (10 cases of toxic gas,7 cases of pesticide,6 cases of drug,3 cases of alcohol and 2 cases of chinese herbal medicine) died of acute poisoning during the period from October,2001 to June,2012 were retrospectively reviewed.Results Gross Changes were found on gross examination in 22 of the 28 cases studied.Of them,7 cases died of acute carbon mono-xide poisoning had showed cherry red of Shiban,muscle,visceral organs and blood.In addition,11 and 8 cases had been found gastric mucosa hemorrhage and epicardium petechial hemorrhage respectively.Histologically,myocardial interstitial hemorrhage was observed in 9 cases,pulmonary hemorrhage in 18 cases,bronchospasm in 12 cases,cerebral hemorrhage in 4 cases,hepato-cyte necrosis in 11 cases,renal tubular necrosis in 7 cases and gastric mucosa hemorrhage in 11 cases.In 6 cases of oral pesticides poisoning,besides they had all gastric mucosa hemorrhage,the change of character of gastric contents was found in 3 cases and pesticide odor from stomach in 3 cases.In addition,acute inflammatory and necrosis of gastric wall in 6 cases of oral pesticides poisoning were observed under the light microscope.Drug addicts often suffered from chronic lesions in multiple organs,such as chronic liver disease,fatty infiltration of the myocardium with myocardial atrophy,interstitial lung disease and pulmonary foreign body granuloma.Conclusions Pathology examination is helpful in the diagnosis of some lethal cases due to acute ooisoning,and it can provide pathological basis to study on treatment of acute poisoning.

Objective To study the application and significance of constructivism theory in pathological experiment teaching.Methods Six classes in total of 198 students majoring in clinical medicine were selected from grade 2009 of Guangdong medical college for research and were divided into experimental group (n=99) and control group (n=99) using random number table.Various teaching methods based on constructivism theory were used in experimental group while conventional teaching methods were applied in control group.The observing ability for specimen and slices,theoretical level and learning behavior of students were assessed with the same standard and anonymous homemade questionnaire survey was executed for students.SPSS 13.0 statistical software was used to analyze the results.The examination results of the two groups were compared using independent samples t-test.The questionnaire survey results of the two groups were compared using Wilcoxon rank-sum test.P<0.05 represented the difference having statistical significance.Results The observing capability for specimen and slices,theoretical level and learning behavior of students in experimental group were significantly improved (P<0.01)and the questionnaire survey results demonstrated that there were statistical difference in feedbacks between the two groups and the satisfaction rate was significantly improved in experiment group (P<0.01).Conclusions Applying comprehensive teaching methods based on constructivism theory can stimulate students' interest and initiative in learning,improve students' learning behavior and learning strategies,and significantly improve the teaching quality.

According to the analysis of 9 237 hospitalized type 2 diabetic patients, the prevalence of diabetic retinopathy ( DR )was 32.9% , with the prevalence of mild, moderate, and serious non-proliferative DR and proliferative DR being 10. 1%, 18. 3%, 3.2%, and 1.3% respectively. The prevalence of diabetic macular edema ( DME ) was 3.56% in type 2 diabetics and i 0. 8% in patients with DR. Diabetes duration and proteinuria were the common risk factors of DR and DME.

Objective To investigate the clinical characteristics of diabetic retinopathy(DR)and diabetic nephropathy(DN)and their correlation. Methods All of 9237 hospitalized type 2 diabetes patients from January 2004 to June 2009 were collected. The prevalence and clinical of characteristics of DR and DN as well as their relationship were analyzed. Results The total prevalence of DR was 33.0%(3045/9237),and the prevalence of DR in the microalbuminuria, macroproteinuria and macroalbuminuria combined with renal dysfunction patients were 36.3%(588/1618),53.7%(1113/2074)and 70.7%(1206/1706)respectively.The prevalence of DN was 58.4%(5398/9237). Compared with that in the diabetes patients without DR, the levels of microalbumin and total protein in the urine were higher in the patients with moderate non-proliferative diabetic retinopathy(NPDR), serious NPDR and proliferative diabetic retinopathy(PDR), but the endogenous creatinine clearance rate was lower(P< 0.05). According to the non-conditional Logistic regression model,the risk factors of DR included diabetes duration,urinary protein,fibrinogen, C-reactive protein and peripheral neuropathy, and the risk factors of DN included diabetes duration, HbA1c, systolic blood pressure,urinary protein,low density lipoprotein and DR. Conclusions DR and DN are the chronic microvascular complications in the type 2 diabetes and have higher prevalence. There are good correlations between DR and DN.
