Objective To observe the changes in the pathological diagnosis rate of Graves'disease(GD) and Hashimoto's thyroiditis(HT)in the past 28 years and to probe its relationship to the environmental factors. Methods Statistic analysis was performed on data of thyroid disease,GD,HT and the complications of HT in Department of Pathology(1978-2005)in General Hospital of Tianjin Medical University with Run test,Cox-stuart test,ANOVA,t or t'test and Chi-square test.Results In 28 years there were 243 403 biopsies(average 8 693/ year)including 6 771 cases of thyroid disease(27.8‰),216 cases of GD(0.89‰),352 cases of HT (1.45‰).The biopsy rate of thyroid disease and GD showed a descending tendency since 1982 but an ascending tendency from 1995,furthermore,with GD it showed a descending tendency from 2001 to 2005 once more.While the biopsy rate of HT and GD+HT showed a descending tendency from 1986 and an ascending tendency after 1996,being 1-4 years later than thyroid disease and GD.The biopsy rate of GD+HT and the proportion of HT showed a descending tendency in 2002-2005 and 2003-2005 respecitvely.The average age of total and female patients with GD showed a descending tendency from 1997.The average age of GD was 13.7 years younger than HT,the patients of GDⅠ-type andⅡ-type being younger thanⅢ-type.The average age of lymphoid type(L), oxyphilie epithelium type(O),pronounced epithelium destruction type(P)in HT increased sequentially.In 28 years,there were more female patients with GD and HT,especially with HT.There existed 7.95% hyperthyroidism,6.25% nodular goiter,2.27% carcinoma in HT(more in L-type)and 2.56% hypothyroidism in HT(more in P-type).Conclusion Within 28 years,according to the pathological diagnosis rate,GD,HT,and GD+HT showed phasic tendencies related to drinking low iodine water and the implement of universal salt iodization policies in 1994 and 2000.Therefore,on the levels of genetics and environment,the factors that influence autoimmunity of thyroid gland could not exclude the variations of iodine intake,infection,affection or emotional stress.The mechanism of the changes in the pathological diagnosis rate needs further study.

BACKGROUND: Vascular dementia is a syndrome characterized by cognitive impairment, which is induced by ischemic or hemorrhagic apoplexy or ischemic-anoxic brain injury. It is assigned to "imbecility", "dementia", "sluggish consciousness", "susceptible to forget things" etc. By traditional Chinese medicine. Impairments of memory and cognition etc. Caused by dementia seriously affect psychosomatic health and quality of life of elderly people.OBJECTIVE: To observe the effects of shuanggen cephalocathartic decoctum on learning, memory and spatial discrimination ability of vascular dementia rats.DESIGN: Randomized control trail taking experimental animals as objects.SETTING: Teaching and Research Section of Basic Theory of Traditional Chinese Medicine, Preclinical Medicine College, Nanjing University of Traditional Chinese Medicine.MATERIALS: The experiment was performed in Laboratory of Viscerastate of Teaching and Research Section of Basic Theory of Traditional Chinese Medicine, Preclinical Medicine College, Nanjing University of Traditional Chinese Medicine, from January to February 2004. A total of 40 male SD rats were selected and randomly divided into sham operation group, model group, model plus traditional Chinese medicine group and model plus Western medicine group, with 10 in each group. Before the experiment, all the rats were adaptively fed for one week, free drinking and eating before and during the experiment. Medicine and reagent are shuanggen cephalocathartic decoctum and Nimotop tablet, and main experimental apparatuses are DTT-2 jumping apparatus and SMG-2 water maze apparatus.METHODS: Blood was collected from left ventricle under aseptic condi tion, and dried in incubator at 37 ℃, after trituration, it was sifted with sieve of 200μm meshes and embolus was prepared. 1 mg embolus and 0.3 mL physiological saline was mixed and shaken up into suspension. Common carotid artery was temporarily occluded with a vascular clamp, and external carotid artery was retrogradely intubated and the embolus suspension was injected into encephalon to establish model of multiple cerebral infarction. In sham operation group, canulate tubule was intubated only to the bifurcation of common carotid artery, with no fluid injected in. Before the experiment, rats in model group and sham operation group were normally fed, while rats in model plus traditional Chinese medicine group were additionally given shuanggen cephalocathartic decoctum [4 g/(kg·d)] infusion and rats in model plus western medicine group were additionally given Nimotop [2 mg/(kg·d)] infusion, once a day for consecutive 15 days. Passive escape jumping experiment was conducted on rats in each group on the 9th day.Recorded the reaction time for rat jumping onto the rubber cushion after electric shock and the frequency of mistakes of suffering electric shock due to jumping down from the platform in 3 minutes, and took the results as learning indexes. The test was repeated on the 10th day. Put the rat into the box for 3-minture adaptation, then put it on the rubber cushion; recorded the latency for rat first jumping down from the rubber cushion and the frequency of jumpingdown from the rubber cushion in 3 minutes, and took the results as memory indexes. Water maze spatial discrimination experiment was conducted on rats in each group on the 11th day, recorded the frequency of mistakes of rats entering dead end and the latency for landing on safe platform. Every time, took a 40-second rest after swimming. Each rat was trained 10 times a day for consecutive three days. MAIN OUTCOME MEASURES: Results of passive escape jumping experiment and water maze spatial discrimination experiment. RESULTS: Each group had a rat dead in the process of operation except sham operation group in which all rats moved normally. Totally 37 rats entered results analysis. ① Results of passive escape jumping experiment: On the 9th day, compared with model group, the reaction time of rats in sham operation group, model plus traditional Chinese medicine group and model plus western medicine group significantly shortened (P < 0.01 -0.05), the frequency of mistakes in 3 minutes remarkably decreased in sham operation group and model plus traditional Chinese medicine group (P < 0.05); on the 10th day, the latency was significantly prolonged in sham operation group as compared with model group (P < 0.05); compared with model group, the frequency of mistakes in 3 minutes significantly decreased in sham operation group, model plus traditional Chinese medicine group and model plus western medicine group (P < 0.05). ② Results of water maze spatial discrimination: On the 3rd day, compared with model group, the frequency of mistakes of rats entering dead end significantly decreased in sham operation group, model plus traditional Chinese medicine group and model plus western medicine group (P < 0.001-0.05); the frequency of mistakes in model plus traditional Chinese medicine group obvi ously decreased as compared with model plus western medicine group (P < 0.05). During the 2nd and 3rd days of water maze experiment, the time for the rat reaching terminal was significantly shortened in sham operation group, model plus traditional Chinese medicine group and model plus western medicine group as compared with model group (P < 0.05).CONCLUSION: Shuanggen cephalocathartic decoctum can significantly improve learning and memory ability of rat model of vascular dementia, and is more effective than Nimotop in the aspect of improving spatial discrimination ability of rat.
