Objective To observe the effect of propofol target-controlled infusion on stress response during nasoscopic procedures.Methods Totally 40 patients with ASA gradesⅠ-Ⅱ scheduled for the nasoscopic operation ware randomly divided into two groups:Group A(propofol continuously injection,2.5 mg?kg-1,n=20)and Group B(propofol target-controlled infusion,4 ?g?ml-1,n=20).The operations were all performed under general anesthesia.Venous blood samples were taken to measure cortisol and blood glucose at three time points:before operation,at 30 min after the operation started,and 60 min after the endotracheal catheter was withdrawn.Meanwhile,HR and MAP of the patients were recorded.Results At both 30 min after the operation started and and 60 min after the endotracheal catheter was withdrawn,Group A showed significantly higher MAP and serum levels of glucose and cortisol than Group B.At 30 min after the operation started:HR:(73?8)/min vs(65?13)/min,t=2.344,P=0.024;MAP:(74?7)mm Hg vs(68?7)mm Hg,t=2.711,P=0.010;blood glucose:(6.28?0.11)mmol/ml vs(5.31?0.15)mmol/ml,t=23.321,P=0.000;cortisol:(125.3?11.5)ng/ml vs(89.6?9.9)ng/ml,t=10.521,P=0.000.At 60 min after the endotracheal catheter was withdrawn:MAP:(79?6)mm Hg vs(73?8)mm Hg,t=2.683,P=0.011;blood glucose:(6.18?0.09)mmol/ml vs(5.62?0.16)mmol/ml,t=10.082,P=0.000;cortisol:(169.1?16.3)ng/ml vs(149.5?15.3)ng/ml,t=3.921,P=0.000.Conclusion Propofol target-controlled infusion can inhibit the stress response caused by nasoscopic operation.

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.

ObjectiveStudy the efficacy of physiotherapy (PT) in the rehabilitation of the patients with Guillain-Barre syndrome. Method15 patients with Guillain-Barre syndrome were divided into 2 groups,exercise group(8 cases) and control group(7 cases),a retrospective study is made.ResultAs compared with control group, there is a significant improvent in muscle strenth and ADL in exercise group (P<0.01).ConclusionPT can effectively diminish the degree of disability of the patients with Guillain-Barre syndrome, shorten rehabilitation time ,and restore independence of self-care.

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.

Objective To evaluate the accuracy of endoscopic ultrasonography (EUS) in preoperative TNM staging of gastric cancer.Methods EUS and abdominal helical computed tomography (HCT) were performed one week before the surgery in 126 gastric cancer patients who would receive surgery to determine the depth of tumor invasion (T),lymph node metastasis (N) and distant metastasis (M) stage and which were also compared with pathologic TNM stage after surgery to evaluate the accuracy of EUS in TNM staging.Pairing x2 test was performed for data analysis.Results Compared with pathologic TNM stage after surgery,the accuracy of EUS in T1,T2,T3 and T4 staging of gastric cancer were 84.6％,14/18,82.0 ％ and 85.7％ respectively.The accuracy of EUSin N0,N1,N2 and N3 staging of gastric cancer were 74.2％,75.0％,57.9％ and 5/17 respectively.The accuracy of HCT in N0,N1,N2 and N3 staging of gastric cancer were 80.6％,75.0％,73.7％ and 12/17 respectively.The accuracy of EUS was similar to HCT in N0 and N1 stage.For N2 and N3 stage,HCT was obviously better than EUS (x2 =4.89,P=0.027; x2 =13.88,P＜0.01).The accuracy of EUS and HCT in M1 stage of gastric cancer were 36.4％ and 95.5％respectively,HCT was better than EUS in M1 determination (x2 =7.90,P=0.001).Conclusions The clinical application value of EUS in the preoperative gastric cancer T staging was high,however the accuracy in determining lymph node metastasis N2 and N3 staging and distant metastasis M staging should be improved.In order to acquire more accurate preoperative TNM stage to guide the treatment selection,the combination with HCT examination is necessary.

2 mg/dl);the others were in the low-risk group.High-risk patients received more superselective embolization with lower dose of embolization agent and fewer numbers of procedure(1.4 vs 2.3,P

Objective To review the diagnosis and treatment of adrenal myelolipoma(ML).Methods The medical records of 21 patients with adrenal myelolipoma were reviewed.All patients were examined by B-ultrasound,CT and endocrine tests while some were also examined by MRI and 131I-MIBG.Results All patients had undergone resection of adrenal ML.The mean diameter of tumors was 6.7 cm(4.5 cm～12 cm).Pathological examination of all tumors confirmed the diagnosis of adrenal ML.No recurrence was recorded during the follow-up period(1～15years).Conclusion Adrenal ML is a kind of rare,benign tumor and is often incidentally discovered.Its prognosis is generally good.
