OBJECTIVE To explore the causes, predilection sites and treatment of nasal sinus mucoceles after hypophysectomy.METHODS The clinical data of 7 cases with nasal sinus mucoceles after hypophysectomy diagnosed and treated in our Department from Jan.1998 to Aug.2007 were retrospectively studied.RESULTS The mucoceles were located at ethmoid sinus in 2 cases,frontal sinus in 2 cases,frontal and ethmoid sinuses in 3 cases.All of the 7 cases underwent mucocelectomy under nasal endoscope or a combined endoscopic intranasal and extra-nasal approach.No recurrence was found after follow up for 1 to 3 years.CONCLUSION The causes of nasal sinus mucoceles after hypophysectomy are the change of the anatomic structure of nasal cavity after surgery.The stenosis,adhesion of middle nasal meatus or obstruction of the sinus ostium are found in all the patients.Intranasal endoscopic surgery or combined with extra-nasal approach is the first choice for nasal sinus mucoceles.

Fire-dragon moxibustion is a modified moxibustion method based on the traditional moxibustion therapy. It’s more easy-to-operate, has higher security, and is more significant in supplementing yang qi. Via extensive and intensive hot stimulation, fire-dragon moxibustion can activate yang qi inside human body, regulate Zang-fu organs, modulate immune function, and finally achieve the goal of preventing and treating diseases.

Purpose To study the value of the ultrasonic imaging in the diagnosis and differential diagnosis of benign and malignant breast tumor. Methods Color doppler ultrasound examination were conducted in 262 cases of patients with breast tumor. The mor-phology of the tumor, edge, envelope, internal echo, microcalcification, length and breadth ratio, axillary lymph node and blood-flow signals of color doppler in breast tumors were observed and these results were compared with the pathological observation postoperation. Results There were 314 tumors in all cases, the coincidence rate in the diagnosis of benign breast diseases with ultrasonic imaging and pathological diagnosis was 97. 3%, the misdiagnosis rate was 2. 7%. The coincidence rate in the diagnosis of breast malignant tumors with ultrasound imaging and pathological diagnosis was 92. 9%, the misdiagnosis rate was 7. 1%. There were statistically signif-icant differences between benign tumors and malignant tumors in the tumor shape, edge, echo, microcalcification, length and breadth ratio, axillary lymph node imaging characteristics (P<0. 01). Conclusion Ultrasound imaging can be more accurate diagnosis and i-dentification of benign and malignant breast tumors.

Objective To study the mechanism of rat blood pressure lowered by SO2 and SO2 derivatives.Methods 6-Keto-PGF1? and TXB2 were determined by radioimmunoassay in the plasma and aorta tissue of rats.Results The 6-Keto increased significantly in the isolated aortic rings in all exposure groups except 8 mmol/L group.No change of TXB2 was observed in the rings in all exposure groups.Meanwhile,6-Keto/TXB2 ratios increased significantly at 2 mmol/L and 4 mmol/L.Compared with the control group,6-Keto level decreased significantly in the plasma of the rats exposed to SO2 at 14 mg/m3,28mg/m3 and 56 mg/m3,but the level of TXB2 increased significantly.6-Keto/TXB2 ratios decreased gradually with the increase of SO2 concentration.Conclusion PGI2 and TXA2 are possibly changed by SO2 and SO2 derivatives,which regulates partly rat blood pressure.

Objective: To investigate the 18F-FDG PET myocardial scintigraphy and Coronary CT angiography (CTA) combination improve coronary heart disease clinical diagnosis level, and the diagnosis of coronary heart disease treatment technology of standardization for clinical application. Methods:The use of positron radionuclide drug 18F-fluorodeoxyglucose (18F-FDG) was made in 35 patients with myocardial metabolic imaging of coronary arteries and CTA examination, 20 patients with myocardial infarction patients, the FDG PET myocardial scintigraphy and coronary artery CTA combine examination results and confirmed case comparison of results. Results: 18F-FDG PETmyocardial scintigraphy and coronary artery CTA combination in the diagnosis of coronary heart disease, sensitivity and specificity of 100%and 96%. Conclusion: 18F-FDG PET data and coronary artery CTA precision data fusion, the fusion image is accurate, can not only provide clinicians reflect coronary artery anatomy indicators, can also provide reflect myocardial pathological physiology and metabolism index, to verify and supplement each other between the indicators.

Objective To explore the application value of the diffusion-weighted imaging (DWI)and dynamic contrast-enhanced MRI in detection of peripheral zone of hepatic alveolar echinococcosis (HAE).Methods Twenty patients with HAE underwent abdominal plain scan,DWI and dynamic enhanced MRI.The ADC values and enhanced ratio of the central necrosis,solid component,peripheral zone and normal liver parenchyma were measured at a workstation,and further were analyzed and compared.Results 32 lesions were detected in 20 patients with HAE.Two groups were divided according to the lesion with central necrosis (group A)or not (group B).In group A, the ADC values of the solid part and normal liver parenchyma were (1.52±0.30)×10 -3 mm2/s and (1.22±0.30)×10 -3 mm2/s. Meanwhile,in group B those were (1.50±0.25)×10-3 mm2/s and (1.03±0.28)×10-3 mm2/s,exhibiting no statistical differences between the two groups.In group A and B,the ADC values of the peripheral zone of lesion were 1.34(1.10,1.61)×10 -3 mm2/s and 0.96 (0.86,1.22)×10 -3 mm2/s,exhibiting statistical differences (Z =2.867,P =0.004);meanwhile,the enhanced ratio were 1.70± 0.36 and 1.58±0.30,exhibiting no statistical difference.No correlation between ADC values and enhanced ratio was found in the peripheral zone.Conclusion DWI at 3.0T can display visually the HAE,and the ADC value may reflect the DWI features of periph-eral zone.The ADC values in combination with enhanced ratio may help for the diagnosis.

Objective To explore the consistency of chemiluminescence microparticle immunoassay(CMIA)reagent and particle‐enhanced turbidimetric immunoassay(PETIA) reagent for detecting pepsinogen(PG) ,so as to provide laboratory references for en‐suring the reliability of PETIA reagent in detecting PG .Methods According to the requirement of EP9‐A2 file made by the Nation‐al Committee for Clinical Laboratory Standards(NCCLS) ,taking PETIA as evaluating method and CMIA as reference method ,a to‐tal of 92 specimens collected from patients with various degrees of gastric atrophy were selected ,PETIA and CMIA reagents were utilized for bidirectional detection of PG .Then recorded test results of pepsinogenⅠ(PGⅠ) ,and PGⅠ /pepsinogenⅡ(PG Ⅱ) rati‐o ,and carried out method comparison and bias evaluation for the two kinds of reagents .Results The expected relative bias of detec‐tion results of PGⅠ and PGⅠ /PG Ⅱ ratio by using PETIA and CMIA reagents were acceptable within linear range of methods . Conclusion The results of PGⅠ and PG Ⅱ detected by using PETIA reagent could be accepted .

Objective: To investigate the current situation of consumption and development tendency of antitumor Chinese herbal injections in Wuhan area. Methods:The analytical method of the defined daily dose ( DDD) recommended by WHO was used to ana-lyze the application of antitumor Chinese herbal injections in 32 hospitals of Wuhan area during the period of 2010-2012. Results:The consumption sum and the DDDs of antitumor Chinese herbal injections were increased year after year, while the daily drug cost ( DDC) was stable in general. The sort of consumption was generally in accordance with the sequence of DDDs. Conclusion:The status quo of antitumor Chinese herbal injections during the period of 2010-2012 is in line with the characteristics of clinical application, indicating the use is rational.

The demands for Traditional Chinese Medicine(TCM)standardization are rising internationally,but the development for TCM intemational standards is confronted with competence.In this context,the authors analyzed the competing status of intemationalized TCM standardization from 3 aspects:1.It is the key point for competition that obtaining leadership in the international organization and dominant position in developing important intemational standards:2.Integrating technical development and intellectual property with intemational standards has been gradually formed;3.Striving to make breakthrough in the development of TCM international standards on the basis of TCM Chinese national standards.The authors recommend that international standards be initiated from TCM service standards.TCM products quality standards and TCM process standards.
