OBJECTIVE To observe bacterial changing-pattern and drug-resistant pattern for reasonable application of antibiotics.METHODS We reviewed the data of 2002-2005 pathogens tests.RESULTS Of 6041 isolated pathogens,2765(45.8%) were Gram-negative bacilli,1350(22.3%) were Gram-positive cocci and 1926(31.9%) were fungi.Fungi increased almost twice,from 18.4% in 2002 to 36.4% in 2005.The most common Gram-negative bacilli were Escherichia coli,Klebsiella pneumoniae and Pseudomonas aeruginosa.While the most common Gram-positive cocci were Staphylococcus epidermidis,S.aureus and Enterococcus faecium.Compared with that in 2002,MRSA,MRSE,ESBLs-producing and AmpC-producing bacilli were significantly increased.Neither strains of S.epidermidis nor strains of S.aureus were found resistant to vancomycin.Carbapenems were the most active antibiotics tested against Gram-negative organisms.CONCLUSIONS We should recognize drug sensitive test as well as restrict the indication of antibiotics application,in order to reduce the occurrence of bacterial resistance.

Objective To represent the high-resolution ultrasonic profiles of diffuse sclerosing variant of papillary thyroid carcinoma (DSVPTC) and highlight the importance of ultrasound examination for detecting this rare entity. Methods The document of clinical presentations and thyroid ultrasound imaging information leading to correct diagnosis were reviewed in association with the microscopic findings of excised thyroid specimen. Results The average age of the eight patients was (18.88 ± 3.59) years(range from 12 to 24) with a gender ratio of 2 males to 6 females. Their predominant clinical presentations were enlargement (8/8) and hardening(6/8) of the involved thyroid lobes. The ultrasound imaging features were increase in the width and thickness of involved thyroids, hypoechoic and heterogeneous internal echoes, containing multiple,diffuse,and fine hyperechoic spots but without formation of any masses, and multiple enlarged lymph nodes in the bilateral jugular chains due to cancer cell metastasis. Ultrasound diagnosis of the first case was malignant thyroid tumor, but the following consecutive 7 patients were all definitely interpreted as DSVPTC. Conclusions The clinical presentations alone is less valuable in diagnosis of DSVPTC, but the characteristic features on high-resolution ultrasonography are highly sensitive and indicative.

OBJECTIVE To investigate the clinical application of antimicrobial agents and give corresponding analysis.METHODS Totally 1453 cases from Dec 2005 to Jan 2006 were investigated retrospectively according to questionaire,and the usage of antibiotics was analyzed according to the standards.RESULTS Among 1453 cases,1155 cases used antibiotic and accounted for 79.5%,of which 47.3% cases were for single-drug therapy,44.1% cases for dual-drug therapy,7.4% cases were for tri-drug therapy and 1.2% cases for more than four kinds drugs.The top five departments in usage amount of antibiotics were stomatology,burn,surgery,pediatrics and respiratory departments.The most common antibiotics were cephalosporins,nitromidazole and catastaltica containing enzymes.The main irrational application of antibiotics included medication without indication,using high standard medicine and illogicality course of treatment and so on.CONCLUSIONS The application of antibiotics in internal medicine still has some irrational phenomenon,therefore,the training of correlated knowledge and regulations should be strengthened.

Objective To detect the expression change of ETFβin diabetic nephropathy rats and study the role of ETFβin fatty acid-induced apoptosis in renal tubules.Methods Diabetic nephropathy model was established by intraperitoneal injection of streptozotocin and unilateral nephrectomy.In vivo ETFβexpression was detected in renal cortex, as well as tubular injury evaluated.In vitro fatty acid-induced apoptosis in renal tubular cells NRK 52E model was established and ETFβrecombinant plasmid was constructed to be transfected into NRK 52E cells and furtherly to observe the effect of ETFβover-expression on the fatty acid-induced apoptosis.Results In the rats model of diabetic nephropathy induced by streptozotocin injection and unilateral nephrectomy, ETFβmRNA and protein expression were decreased as obvious tubular damage occurred.Fatty acids could induce apoptosis in NRK 52E, and ETFβover-expression reduced the apoptosis.Conclusion The expression of ETFβis decreased in diabetic nephropathy model , and ETFβover-expression can reduce apoptosis induced by fatty acid in renal tubular cells.
