Objective To discuss the difference of levels of serum and urinary iodine and thyroid function in painless thyroiditis patients and other thyroiditis patients.Methods The patients who were preliminary diagnosed as having higher level of serum thyroid hormone were divided into Graves' disease group,subacute thyroiditis group and painless thyroiditis group.Then all the patients were divided into another two groups according to the level of autoantibody.The value of serumal thyroid hormone and serumal iodine and urinary iodine were measured and the relationship between the groups and the value were observed.Results There was close relationship between serum T 3,T 4,urinary iodine and the types of thyrotoxicosis.Conclusion The morbidity of painless thyroiditis is not uncommon.Clinical situation,serumal iodine,urinary iodine and serumal thyroid hormone may be useful for clinical diagnosis and differential diagnosis of painless thyroiditis.

Objective To investigate improvements in the diagnosis and treatment of primary malignant tumor of the duodenum. Methods The clinical data of 54 patients with primary malignant tumor of the duodenum treated during a period of 6 years were analysed retrospectively. Results Tumors located in the first, second, third and fourth parts accounted for 6 cases(11.1%), 44 cases(81.5%), 2 cases(3.7%), and 2 cases(3.7%) respectively; and among them, ampullary tumor accounted for 38 cases(86.4%) of tumor of descending portion of duodenum and 70.4% of the total number of duodenal tumors. The main clinical presentation included jaundice, upper abdominal pain, weight loss, abdominal distention, and gastrointestinal obstruction. Upper abdominal pain, no positive signs and abdominal mass were found in 72.0%, 20.0% and 8.0% respectively on abdominal examination. Preoperative associated cholecystopathy accounted for 37.0%. The accuracy rate of duodenoscopy and ERCP in preoperative diagnosis was 94.4%, and 77.8% respectively. Preoperative diagnostic accuracy rate was 27.8%. Panceaticoduodenectomy was performed in 38 cases, duodenectonmy in 1 case, palliative resection of tumor in 9 cases, and tumor was inoperable in 6 cases. Radical resection rate was 72.2%. The postoperative 3- and 5-year survival rate was 40.6% and 21.9%, respectively. After palliative resection, death occurred from 1month to 24months. Conclusions The tumors in the ampullary region account for the majority of primary malignant tumors of the duodenum and are mainly adenocarcinoma. The symptoms of advanced stage are complicated, and specific signs on abdominal examination are few. Associated cholecystopathy is relatively ferquent and preoperative accurate diagnostic rate is low. The examinations of first choice are duodenoscopy and ERCP, and radical panceaticoduodenectomy can extend survival time.

Objective To investigate the effects of C-terminal fragment of parathyroid hormonerelated protein (PTHrP107-139) on bone mineral density (BMD), bone histomorphometry and biomechanical properties in ovariectomized (OVX) rats and its effect on bone metabolism is also explored. Methods Forty 4-month old female Wistar rats in which 30 were ovariectomized and then divided into 3 groups: the placebo, the PTHrPC and the CT groups, the other 10 rats were Sham-operated as the control group (Sham). Five weeks later, the rats of PTHrPC and CT groups were subcutaneously injected with PTHrP107-139 (40 μg/kg) and Salmon Calcitonin (15 U/kg) respectively once every other day. The rats of the placebo and sham groups were injected with 0.2 ml saline once every other day. After treatment of 12 weeks, all rats were sacrificed and all samples were collected and analyzed. Results ① Compared with the placebo, the BMD and bone strength of PTHrPC and CT groups were significantly increased (P<0.05). ② Histomorphometry revealed that the tetracycline labeled bone surfaces, osteoid surfaces, mineral apposition rate and bone resorption rate were remarkably decreased in PTHrPC, and CT groups comparing with those of the placebo group. Conclusion Cter-minal PTHrP107-139 is effective in increasing the BMD, bone strength and quality when administered intermittently to ovariectomy-induced osteoporotic rats. Its increasing in bone quality may relate to reducing bone turnover and inhibiting resorption.

The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

BACKGROUND: Learning and memory disorder exist in diabetic rats,which can be improved by APP 17-mer peptide. However, it is unclear whether learning and memory disorder in diabetes mellitus is caused by influencing neuronal mitochondrial transmembrane potentials and apoptosis in hippocampus or not and what is the related action mechanism of APP17-mer peptide.OBJECTIVE: To observe the effects of APP17-mer peptide on neuronal mitochondrial transmembrane potentials (△ψm) and apoptosis in hippocampal area of diabetic rats.DESIGN: A completely randomized, grouping and controlled trial.SETTING: Beijing Research Laboratory for Brain Aging, Beijing Xuanwu Hospital, Capital University of Medical Sciences; the Department of Endocrine, the First Central Hospital of Baoding.MATERIALS: The data measurement of the experiment was carried out in the Instrument Testing Center, the General Hospital of Chinese PLA between May 2002 and August 2002. The modeling and intervention of the experiment was carried out in the Animal Laboratory of Xuanwu Hospital, Capital University of Medical Sciences. Eighteen male Wistar rats were enrolled and randomized into control group, model group and APP17-mer peptide group with 6 rats in each group.METHODS: ① Diabetic models in the model and APP17-mer peptide groups were established by intraperitoneal injection of 60 mg/kg streptozotocin (pH=4.4) in fasted rats(fasting for 12 hours). Three days later, modeling was successful if blood sugar level in caudal vein was more than 15 mmol/L. Rats in the control group were not subjected to modeling.Then, the rats in the APP17-mer peptide group were subjected to the subcutaneous injection of APP17-mer peptide (3.4 μg for each rat once) three times a week and totally for ten weeks, whereas rats in the other groups were given saline of the same volume. ② After ten weeks, rats were anesthetized and decapitated to take out brain tissues, and then hippocampal tissues were isolated in ice bath for preparation of single cell suspension.JC-1 labeled mitochondrial transmembrane potentials and cell apoptosis in hippocampal area were measured by means of flow cytometry. ③ One-way analysis of variance was adopted in the comparison among groups.RESULTS: Eighteen rats were involved in the results analysis. ①Neuronal mitochondrial transmembrane potential was lower in the model group as compared with the control group [(551.91±53.36) vs (809.88±82.41) △ψm,P<0.01] while it was higher in the APP17-mer peptide group as compared with the model group [(705.99±89.92) vs (551.91±53.36) △ψm, P < 0.05].There was no difference between the APP17-mer peptide group and control group (P=0.146). ②) Apoptotic percentage of single cell in hippocampus was significantly higher in the model group than in the control and APP17-mer peptide groups [(5.32±1.37)%, (1.03±0.55)%, (2.80±0.92)%, P<0.01, 0.05].CONCLUSION: Neuronal mitochondrial transmembrane potential and cell apoptosis in hippocampus may be involved in the occurrence and development of diabetes mellitus, and APP17-mer peptide plays an improved role in the process.
