Professor OUYANG Hui-qing's gradually formed her own teaching concept of traditional Chinese medicine through long-term teaching practice:the most important teaching aim is to cultivate talents of traditional Chinese medicine.Clinical practice together with classroom teaching can promote the growing knowledge of medical students.Clinical practices are necessary and should penetrate culture and academic tradition of traditional Chinese medicine.OUYANG Hui-qing's concepts on talents are:cultivating teaching faculties is the key to the development of the teaching team,the core of construction of the teaching and research section,and the basis of construction of the discipline.OUYANG Hui-qing's management concepts are:the dean of the teaching and research section is the practitioner of personnel training practice and the undertaker of teaching team development.

Immunohistochemical technique was an essential tool of conventional diagnosis,therefore,the application of immunohisto- chemistry in reformation of pathology laboratory teaching would boost pathological experimental teaching standards to a higher level.

Objective To investigate the effect of heat stress on organ indices, intestinal morphology, gastric mu-cosal HSP70 mRNA expression and glucose metabolic hormones in mice.Methods A single-factor experiment was de-signed for the present research.Eighteen KM mice of the similar age and weight were randomly divided into control group and heat stress group.The weight of the heart, liver, spleen, lung and kidney, as well as the expression of HSP70 mRNA in the mouse gastric mucosa were measured.The plasma concentration of insulin and glucagon, the villus height and crypt depth of the duodenum and jejunum were detected.The histological changes of the liver, duodenum and jejunum were also examined.Results There was no effect of heat stress on the organ indices.It significantly increased the expression of HSP70 mRNA in the gastric mucosa, reduced the plasma insulin level and caused serious injury to the liver, duodenum and jejunum in the mice.Conclusions Heat stress does not significantly affect the organ indices in mice, but can significantly increase the expression of HSP70 mRNA in the gastric mucosa, cause apparent damages in the liver, duodenum and jeju-num, reduce the villus height, crypt depth and villus height/crypt depth ratio of the duodenum and jejunum, and also de-crease the blood insulin concentration in the mice.

In order to meet the needs of new clinical professional training reform,develop practical,clinical thinking,communication and teamwork,the teaching of diagnostics was reformed.We integrated diagnostics,internal medicine,surgery,gynecology,pediatrics and basic practice,reduced the theoretical class hours,increased the teaching hours,innovated and enriched teaching methods,standardized the content of assessment and grading standards,and emphasized formative assessment.The preliminary results showed that the students had a high evaluation of the quality of self learning and teaching satisfaction,which indicates that it met the requirements of the syllabus,and students had good grasp of the basic clinical skills

Objective To explore the abnormally functional brain regions of female patients with depression by resting state functional magnetic resonance imaging (fMRI),and analyze the correlation with the severity of depressive symptoms.Methods 32 female patients diagnosed with depressive disorder and 40 matched healthy controls completed resting state fMRI scans.The whole brain's regional homogeneity (ReHo) and amplitude of low-frequency fluctuation(ALFF) were calculated,and the correlation analysis be tween ReHo and ALFF of brain regions with significant difference and the severity of depressive symptoms was conducted.Results Compared with control group,the left precuneus/left cuneus (MNI:-18,-81,45),bilateral precentral gyrus (MNI:-58,-5,35 and 57,-6,33),left inferior parietal lobule (MNI:-42,-36,45) and right inferior temporal gyrus(MN1:60,-45,-18) (P＜0.05,corrected by AlphaSim)in the case group showed significantly decreased ReHo,with statistical significance.Compared with control group,the left cuneus(MNI:-3,-87,30),right inferior temporal gyrus(MNI:60,-48,-18) and left precentral gyrus(MNI:-63,-3,26) (P＜0.05,corrected by AlphasSim)in the case group showed significantly decreased ALFF.The ReHo in the right inferior temporal gyrus was negative correlated with the HAMD-17 total score and retarda tion factor(r=-0.484,P=0.017;r=-0.408,P=0.048),the ALFF in the right inferior temporal gyrus was positively correlated with weight factor(r=0.574,P=0.003),and negative correlated with the number of depressive episodes(r=-0.416,P=0.043).Conclusion Female with depression in resting state have several abnormally functional brain regions and the extent of damage is correlated with the severity of depressive symptoms.Combination of the two parameters may yield a more comprehensive pathophy-siological mechanism for depressive disorder.

Objective To evaluate the post-operative glucose level and insulin dose of patients undergoing total pancreatectomy.Methods From September 1980 to September 2014, 21 patients underwent total pancrea-tectomy in Peking Union Medical College Hospital, who were enrolled in our study.We reviewed the changes in their insulin dosage and glucose levels after operation, also summarized type and dose of insulin as well as glucose level in stable period.Results The required insulin dose reached peak within 4 days after surgery ( maximum dose 300 U/d).The average dose was (143.5 ±62.8) U/d and decreased gradually.During the perioperative period (needing parenteral nutrition), the blood glucose level fluctuated markedly (1.52-29.06 mmol/L) and the average level was (11.18 ±0.95) mmol/L.During the stable period ( without parenteral nutrition) , patients on average had (5.3 ±2.0) U of preprandial rapid-acting insulin and (8.1 ±2.9) U of long-acting insulin be-fore sleeping;the average fasting blood glucose was (6.69 ±1.48) mmol/L, 2 h postprandial blood glucose was (9.08 ±2.84) mmol/L, bedtime blood glucose was (9.66 ±2.49) mmol/L, and blood glucose level at night was (8.15 ±2.78) mmol/L.67%of the patients had 13 hypoglycemic episodes monthly on average.For those five followed-up patients, the average hemoglobin A1c was (6.15 ±1.20)%.Conclusions Patients undergoing total pancreatectomy may experience marked fluctuation of blood glucose level and short-term increase of insulin need which gradually decreases afterwards.After entering the stable period, the glucose level could be well-con-trolled but with frequent hypoglycemia.There is no diabetic ketoacidosis.

The impact of key physical properties on granulated products by the high-speed mixing wet method was studied. Andrographis extracts were utilized as the model drug. Four processing methods were adopted to prepare mixed powder of microcrystalline cellulose (MCC) and starch with the mass ratio 1:0.5, 1:1 and 1:2 by the high-speed mixing wet method. The properties of the prepared granules were evaluated with such indexes as granule yield, the ratio of lumps and fine powder, granule-AOR and granule-HR. The impact of key physical properties on granulated products was analyzed through stepwise regression analysis. The results showed that angle of repose, moisture content, pore volume, density and contact angle with water were key physical properties of the powder. The key physical properties of Chinese medical extracts powder are the important factor impacting granulated products made by the high-speed mixing wet method. In this study, the impact of key physical properties on granulated products of Chinese medical extracts was analyzed from the physical angle.
