ABSTRACT
Objective To evaluate the methods of diagnosis and treatment of thyroid disease with concomitant focal lymphocytic thyroiditis(FLT), and explore the reasons for its confused with Hashimoto′s disease(HD).Methods During the recent 25 years, 207 patients underwent surgical trearment for pathologically diagnosed HD.Among this group, 143 cases of HD with other concomitant thyroid disease were retrospectively analysed.Results Of the 143 cases, 57 cases were found to have thyroid disease with concomitant FLT, and this was 27.5%(57/207) of the total HD group, or 39.9%(57/143) of the group with thyroid disease and concomitant HD.Intraoperative pathologic section revealed that focal lymphocytic infiltration was positive in 87.7%(50/57) of cases. The postoperative hypothyroidism occurrence rate was 19.3%(11/57), of which, 7 cases(7/57, 12.3%) were subclinical hypothyroidism.Conclusions The character of pathologic changes of thyroid disease with FLT and with HD was different. Intraoperative pathologic section can be helpful in the diagnosis of this condition and can have important significance as a guide to the scope of (surgical) resection of the thyroid gland.
ABSTRACT
Objective To evaluate the clinical parameter, diagnosis and operative mode of parathyroid tumor. Methods The clinical symptoms, examination methods and the mode of operation in 15 operated patients with parathyroid tumor from May 1979 to October 2001 were retrospectively analyzed. Results 15 patients with parathyroid tumors, including 10 adenomas, 3 carcinoma and 2 cysts, all revealed the symptom of hyperparathyroidism except 2 cases of cyst. The accuracy of B-US and CT in preoperative diagnosis on location was 86 7% and 91 7% respectively, and their accuracy in preoperative diagnosis on quality was 26 7% and 75 0% respectively. All patients were treated by surgery. Among them, 12 patients were cured, 1 died, and 2 relapsed. Conclusion If a patient has the symptoms of bone pain, nephrolith and the mass in neck, we should consider whether he suffers from parathyroid tumor. B-US is the first choice in preoperative diagnosis on tumor location, and CT was the good examination method for tumor location also. The diagnosis on tumor quality dependeds on pathological examination mostly. Surgery remains to be the most important. The only unilateral exploration for the benign parathyroid tumor is performed and the operative range of parathyroid carcinoma should include both the mass and thyroid.
ABSTRACT
a adrenoceptor-mediated increases in smooth muscle tone of the prostate gland and urethra acts as a dynamic factor for BPH-related obstruction of the urethra, a1 adrenoceptor antagonists are considered as the first-line therapy for the patients with BPH. The search for selective a1A a-drenoceptor antogonists with high uroselectivity is strategical for drug discovery research.
ABSTRACT
Objective To study the diagnosis and indications of operation of thyroiditis associated with thyroid cancer(TTATC). Methods The clinical data of 16 patients with TTATC were analysed retrospectively. Results All 16 patients were treated surgically, including subacute thyroditis with thyroid cancer in 4 patients, Hashimoto's disease with thyroid cancer in 12. The carcinoma of thyroid were composed of 12 papillary, 3 follicular, and 1 mixed papillary follicular cancer. The 16 patients were followed up for 2 months 9 years, showing they were all alive and healthy. Conclusions In order to avoid delaying the treatment of thyroid cancer, the following thyroiditis with thyroid nodule should be operated earlier: (1) The nodule in thyroditis didn't alter to smaller and shows a tendency to be enlarge after systematic drug therapy. (2) the cold nodule is of cold character in SPECT but solid in ultrasound.
ABSTRACT
Objective To determine the relationship between the microvessel density and the aggressiveness in breast cancer(BC) in young women (≤35years).Methods Immunohistochemical method (SABC) was used to study the expression of MVD on paraffin embedded sections in 40 young women BC patients(age≤35years) and 30 past menstrual BC patients.The relation between axillary lymph node metastasis and the clinicopathological parameters was analyzed and compared.Results The mean value of MVD and the positive rate of axillary lymph node in the young women group(65.28?15.06,70%)were higher than that in the past menstrual group(51.91?15.06,40%)(P
ABSTRACT
m-Nisoldipine ( m-Nis ) , isobutyl methyl 1 , 4-dihydro - 2, 6-dimethyl-4-( 3-nitrophenyl )-3 , 5-pyridine dicarboxylate, is a new calcium antagonist. Its effects on hemodynamics and regional blood flow as well as the distribution of cardiac output were evaluated in comparison with Nis with radio-biomicrospheres in conscious rabbits. ( 1 ) m-Nis ( 1 ?g/kg ? min-1 ? 10 min, iv ) increased cardiac output and cardiac index significantly (P0.05) ; ( 2 ) m-Nis increased stroke volume and left ventricular systolic work ( per beat ) while Nis slightly increased the former and decreased the later, and these differences were statistically significant (P
ABSTRACT
Using method of orthogonal design we observed that low K+,high Ca2+ & low Mg2+ in perfusate produced the peak incidence of reperf-usion-indaced ventricular fibrillation & introduction of K+ & Ca2+ significantly affected the incidence & pnset of it, The appropriate prop-ortion of K+, ea2+ & Mg2+ in perfusate is the important effecting factor of reperfusion-induced arrhythmias in Langendorff heart of rats.
