Application of two dietary survey methods in type 2 diabetes patients / 中华健康管理学杂志

Objective To analyze and compare the differences in application of 24-hour dietary recall and dietary balance index (DBI) in dietary survey and evaluation of patients with type 2 diabetes mellitus,meanwhile investigate their nutrition status.Method This was a cross-sectional study.A total of 100 type 2 diabetes inpatients at the age of 19-59 were recruited from Shanghai Jiaotong University Affiliated Sixth People's Hospital from December 2013 to February 2014.They were surveyed and evaluated by 24-hour dietary recall and DBI respectively.Result The micronutrient intake in patients with type 2 diabetes was not sufficient.Compared with RNI,the intake of vitamin B1,B2,and calcium was less than 50％.The average of DBI lower bound score (DBI-LBS) of the 100 patients was 32.1±6.1,65％; the patients were in moderate or severe deficit of food intake.DBI higher bound score (DBI-HBS) was 4.4±2.8.No significant excess intake problem was found.Dietary quality distance was 36.4±6.9.Eighty-seven percent of them had a dietary patterns of mode B.Conclusion Dietary patterns in type 2 diabetes patients were not reasonable.Nutrition education and nutrition intervention for type 2 diabetes should be emphasized.The two methods can be used to evaluate dietary quality independently,but it would be better to evaluate the quality of the patients' diet using two dietary survey methods together.

Neuropathological characters of delayed cortical infarcts after transient unilateral brain ischemia in Mongolian gerbils / 中华神经科杂志

Objective To investigate the distribution of eosinphililic neurons ( ENs),reactive astrocytes ( RAs),and infarction after transient cerebal ischemia,and the time profile of pathomorphological changes.Methods Unilateral forebrain ischemia was induced in Mongolian gerbils by two 10 minutes unilateral common carotid artery occlusions with a 5 hours interval.Laser Doppler flowmetry was used to detect intra-ischemic anterior cortex blood flow.Animals were sacrificed at 24 hours,4 days,2 weeks,4 weeks,16 weeks and the brain were prepared for pathomorphological assay.Results Intra-ischemic laser Doppler flowmetry show significant ischemia during carotid artery occlusion:22.1％ ± 9.5％,26.3％ ± 4.9％,37.5％ ± 3.5％,F =67.219,P ＜ 0.01 ; the decrease was significantly greater in the anterior cortex.ENs appeared in middle and deep layers at 24 hours postischemia,and ENs area extend to all layers of cortex by 4 days.Large areas of high EN density ( ≥80/mm2) evolved to infarcts between 4 days and 4 weeks.Posterior cortex evolved to low EN area ( ＜ 80/mm2) without transformation into infarcts.RAs were consistently distributed in areas with ENs,and RA areas with high EN density were largely transformed into infarcts between 4 days and 4 weeks. Delayed astrocytic death took place in the RA areas with high EN density.Conclusion Density of ENs is an important indicator of delayed astrocytic death and infarction in postischemic tissue.

Successful reform in experimental teaching of pathology / 中华医学教育探索杂志

Experimental course of pathology is a very important part of pathology teaching.Motivation of students was promoted through improving the professional knowledge of teachers,using teacher-student interacted teaching methods,increasing network courscs,using multimedia in teaching and adding extracurricular practice in our university.In the meantime,it was successful and fruitful to use diversified evaluation systems to assess the comprehensive experimental capacity of students,which can provide experiences in reform of pathological experimental teaching.

Significance of E-cadherin/catenin adhesion complex expression in nasopharyngeal carcinoma / 基础医学与临床

Objective To elucidate the expression pattern of E-cadherin/catenin adhesion complex and its association with pathologic features in nasopharyngeal carcinoma(NPC).Methods Fifty-two non-keratinizing NPC specimens with adjacent non-neoplastic mucosa were examined for E-cadherin,?-CATenin,?-CATenin.Results Abnormal expression rate of E-cadherin,?-catenin and ?-catenin in NPCs were 48.1%(25/52),32.7%(17/52) and 34.6%(18/52),respectively,whereas all adjacent non-neoplastic tissues normally expressed these proteins.Difference of expression of E-cadherin,?-catenin and ?-catenin between tumor tissues and non-cancerous tissues was statistically significant(P

Cognition of and Reflection on the Correlation between Pathology Teaching and Normal Morphology / 中华医学教育探索杂志

In the teaching of pathology,instructor guides students to identify the similar and different spots between affection and normal tissue by previewing and contrasting teaching,so students learn how to discriminate different forms of affection generally and under the microscopic,and associated the clinical symptom.These exercises conduce to cultivate the logical thinking,observation and practice capability of students and do the groundwork for the clinic study.

Hospital Drug Price Levels / 中国药房

1 000 yuan were 68.84%,14.34%,14.35%,2.48%,respectively.In terms of percentages of the categories at the levels above 100 yuan,leading the list were anti-neoplastic drugs,followed in descending order by drugs used for hematological system,anti-neoplastic adjuvants,biological response modifiers,anti-fungal drug and immunosuppressive agents etc.CONCLUSION:Hospital drug price level and percentages at each level tended to be more reasonable after many times policy price reduction.
