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.

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.

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.

Matrix metalloproteinase-9 plays an important role in the blood-brain barrier disruption.Blood-brain barrier disruption may directly influence the neurovascuiar unit repair after cerebral ischemia.An in-depth study of matrix metalloproteinase-9-mediated ischemic brain damage and neurovascular remodeling is expected to open up a new way for the diagnosis and treatment of cerebral ischemia in clinical practice.

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 effectiveness of exposure and ritual prevention of patients with obsession-compul-sive disorder(OCD),so as to provide references for professionals in clinical psychology.Methods:One female patient with severe OCD received 3 weeks intensive exposure and ritual prevention treatment.In order to investigate the effectiveness,she completed Symptom Check List 90 and Yale Brown Obsessive Compulsive Scale(SCL-90 and YBOCS) at pre-treat-ment,mid-treatment and post-treatment.Results:After treatment,the patient's scores of questionnaires reduced,such as score on YBOCS reduced from 38 to 9.She reported that her washing time reduced obviously and her own measure of dis-tress index reduced.Conclusion:Exposure and ritual prevention could treat the patient with OCD effectively.Her distress reduced and life function was improved.

Objective To investigate the expressions of survivin and bcl-2 and their relationships in transitional cell carcinoma of the bladder.Methods The expressions of survivin and bcl-2 in 40 cases of transitional cell carcinoma of the bladder were detected with streptavidin-biotin peroxidase(SP) method,with 15 cases of normal bladder specimens as controls.Results Survivin was expressed in 25 of 40(58.149%) cases of bladder carcinoma tissues,and normal bladder specimens did not express survivin(P

OBJECTIVE:To optimize the approach and methods for the selection of national essential drugs and to improve national essential drug system.METHODS:The concept of national essential drugs and the principle of selecting national essential drugs and the problems within were expounded,and the rationale and methods of pharmacoeconomics were adopted to analyze its significance and role in selecting national essential drugs.RESULTS & CONCLUSION:Simplifying National Essential Drug List can facilitate peoples’ access to essential drugs.

Based on the state of the development of the body and the subcutaneous fat of 4314 students (includidg boys and girls) at four middle schools in Zibo City, the fat was appraised and analyzed by the body-block indexand the thickness of the subcutaneous fat. The stand-ard-proposal value was also put forward by using y+1.645 Sy.x as the dividing-line value of the groups of different ages and the fat of both sexes. The comparison with foreign standards concerned showed that tally rate of the musculus triceps brachii and the shoulder-blade region of the fat sufferers was 76.87% and 51.7%. The tally rate of the sum of the above two terms reached 100% among the male and the female groups, from 15 to 18 years old. According to the current appraisable standard, the rate of fat children and juvenile for male was 2.86%, while for female, 4.0%. It was obvious that the rate of occurrence for female is higher than that for male(P
