ABSTRACT
Objective To study the relation between elderly hypertensive patients with accompanying type 2 diabetes mellitus and characteristics of ambulatory blood pressure. Methods 46 elderly hypertinsive patients with accompanying type 2 diabetes mellitus (experimental group) and 46 patients with essential hypertension (control group) through 24 hours use MEIGAOYI ambulatory blood pressure monitor. Results Comparison finds elderly hypertinsive patients with accompanying type 2 diabetes mellitus have lost normal blood pressure day and night rhythm, especially in aspect of obvious increasing of systolic pressure load and night systolic pressure. The results showed statistically significance (P<0.01,P<0.05). Conclusion For such elderly hypertinsive patients with accompanying type 2 diabetes mellitus treatment on high blood pressure should not only lower down too high blood pressure, but also lower down blood pressure steadily throughout 24 hours in the day and resume day & night rhythm.
ABSTRACT
OBJECTIVE To investigate the clinical practicability of inducible clindamycin resistance and to evaluate the clinical value of cefoxitin disk diffusion method in detecting the mecA gene of meticillin-resistant Staphylococcus(MRS). METHODS Resistant phenotypes were classified with erythromycin and clindamycin discs using the D test method and the cefoxitin disk diffusion method in detecting mecA gene of the staphylococcus. RESULTS Of all 390 Staphylococcus strains,218 strains(55.9 %) were resistant to erythromycin and clindamycin(cMLS).Seventy strains(17.9 %) which were resistant to erythromycin but susceptible to clindamycin showed the positive D test results(iMLS),79 strains(20.3 %) resistant to erythromycin but susceptible to clindamycin showed the negative D test results(MS).From 390 strains of clinical isolated staphylococcus,which using the cefoxitin disk diffusion method,272 strains were MRS. CONCLUSIONS Using the D test method to investigate the inducible resistance to erythromycin and clindamycin in the Staphylococcus strains,which could help the doctors choose correctly the antibiotics such as macrolides and clindamycin.At the same time,cefoxitin disk diffusion method can be used reliably by the clinical laboratory in detecting and conforming MRS.
ABSTRACT
Objective To explore the diagnostic value of needle stereotaction marking by steel wire(NSMSW) under mammography for nonpalpable early stage breast carcinoma (BC). Methods 29 patients with nonpalpable breast lesions were performed NSMSW under mammography,and the lesions were removed for biopsy to make the diagnosis. Results Nine patients(31.0%) were definited as early stage BC and twenty(69.0%) benign disease.The pathologic results in freezing sections and in parafin sections were the same. Conclusions NSMSW under mammography can resolve the problem of accurate location of nonpalpable breast lesions during operation .It is a credible, useful and practical method for diagnosis of nonpalpable early stage BC.
ABSTRACT
Objective To study the effective therapy of breast intraductal papilloma . Method One hundred and thirty-two patients with breast intraductal papilloma (four patients with cancerization)were treated by resection of the tissue stained by methylene blue. The effect was evaluated. Results The pathological diagnosis were 91 patients with breast intraductal papilloma and 41 breast intraductal papillomatosis, and 4 of them were cancerization. One hundred and ninteen patients(90.1%) were followed up for 3～46 months, all patients were cured without recurrence after operation. Conclusions Resection of the tissue stained by methylene blue in treating breast intraductal papilloma is a reliable and effective method.
