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.

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.

Objective To study the effect and the possible mechanism of delavirdine on muhidrng resist-ance-aasociated protein 2(MRAP2)-mediated multidrug resistance in LLC/cMOAT cells. Methods MTT assay was used to determine the effects of delavirdine on proliferation of LLC/CMV and LLC/cMOAT cells. The inhibitory effects of vincristine (VCR),cisplatin (DDP),adriamycin (ADM) and etoposide (VP-16) used alone or in combi-nation with delavirdine on the proliferation of LLC/CMV and LLC/cMOAT cells were evaluated by MTT assay. The cell cycle distribution, the apoptosis rate of the cells treated with different concentration of delavirdine and the intra-cellular concentration of ADM were determined by flow cytometry (FCM). Results Delavirdine at the concentration of 4 μmol/L and below showed no significant cytotoxicity to LLC/CMV and LLC/cMOAT cells. The resistance of LLC/cMOAT cells to VCB, VP-16, ADM and DDP were 9.58,1.11,2.98 and 3.96 folds of that of LLC/CMV cells. When 2 μmol/L delavirdine was added, the resistance was 5.21 and 2.55 folds respectively;when 4 μmol/L dela-virdine was edded,the resistance was 7.56 and 3.03 ,while 2,4 μmol/L delavirdine made no significant changes to the chemosensitivity of LLC/CMV cells to VCR and DDP(P>0.05). Cellular cycle analysis demonstrated that 0,6, 12,24 hours after co-cultured with delavirdine the amount of cells at G1 phase increased from(38.92±0.15)% to (56.87±2.23)%,(65.36±2.76)% and (74.77±5.06)%. The cell apoptosis rate increased from 1.77% to 17.45% and 28.52% when treated with delavirdine at 2,4 μmol/L and VCR for 24 h. When treated with 2,4 μmol/L delavirdine, ADM accumulation in LLC/cMOAT cells was enhanced significantly(P<0.05). Conclusion DLV can partially reverse the multidrng resistance of LLC/cMOAT cells, and the reverse effect correlates to the concentration. The possible mechanism may involve the growth arrest at G1, increasing of intracellular drug concen-tration and promoting apoptosis.

Objective To investigate the association between -45C→G mutation at promoter of human urate transporter 1 gene and primary hyperuricemia. Methods The allele frequency and genotypo distribution of -45 C→G mutation at promoter of human urate trans-porter 1 gene were determined by PCR-RFLP in 217 patients with primary hyperuricemia and 419 normal controls. Results The frequencies of the G allele and CG genotype at promoter of human urate transporter 1 gene in patients were significantly higher than that in normal controls (P = 0. 031, P = 0.031). The levels of serum uric acid (UA) and triglyceride (TG) in subjects of CG genotype were significantly higher than those in the objects of CC genotype(t=3.058, t=3.699, P=0.002, P<0.001). There were no significant difference in the levels of total cholesterol (TC), fasting plasma glucose (FPG), urea nitrogen (BUN), creatinine (Cr) between the two groups (P>0.05). Conclusion The -45 C→G mutation at promoter of human urate transporter 1 gene may be related to primary hyperuricemia.

Objective To investigate the early postoperative rehabilitation condition of patients with cervical spondylotic radiculopathy and analyze its correlation with the life style.Methods A retrospective analysis for 164 cases of cervical spondylotic radiculopathy with complete follow-up data were carried out.Using modified MacNab criteria for evaluation of postoperative recovery.The clinical efficacy was evaluated 3 months after operation,and the patients were divided into satisfactory group (excellent/good) and unsatisfactory group (fair/poor).The influencing factors included general information and the lifestyle such as smoking,drinking,sleep time,the height of the pillow,working time and frequency of physical exercise.The chi-square test and Logistic multivariate regression analysis were used to analyze the effects of lifestyle on early postoperative rehabilitation patients with cervical spondylotic radiculopathy.Results Postoperative efficacy satisfaction of patients evaluated by modified MacNab standard was 88.4％ in 3 months.There were differences in age(x2 =5.819),smoking(x2 =5.074) and frequence of physical exercise(x2 =4.430),and the differences were statistically significant (all P＜ 0.05).Logistic analysis showed that age more than 50 years old(OR=3.913,95％ CI =1.321-11.594,P=0.014),smoking(OR=3.217,95％ CI =1.126-9.195,P =0.029) and frequence of physical exercise less than or equal to 3 times a week (OR=3.906,95％ CI =1.026-14.869,P=0.046) were the risk factors affecting the satisfaction of clinical curative effect of early postoperative cervical spondylotic radiculopathy.Conclusion Age,smoking and physical exercise are related to early postoperative rehabilitation of patients with cervical spondylotic radiculopathy,and then more than 50 years old,smoking and exercise less than 3 times a week have adverse effects on the early postoperative rehabilitation.

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 discuss the application of Prescription Automatic Screening System (PASS) in the examination of clinical medical orders. METHODS: The level and type of caution and the modification rate of medical orders in our hospital between April 2005 and April 2006 were analysed statistically, and the conformity between PASS cautions of medical orders and clinical medications was evaluated. RESULTS: A total of 10 982 160 medical orders were monitored by PASS, of which, 11 146 were with black cautions and in which 2 861(25.67%) were modified, 51 504 were with red cautions and in which 10 357 (20.0%) were modified, 339 449 were with yellow ones and in which 66 022 (19.45%) were modified. In PASS monitor process, inconformity between feasible clinical medical orders and cautions of PASS was noted in a few cases. CONCLUSION: The examination of medical orders using PASS is convenient and rapid and the PASS can help improve clinical rational drug use level, however, its function of remains to be updated and optimized.
