OBJECTIVE To investigate the distribution and resistance rate of clinical isolates from neonatal sepsis in Hubei hospitals.METHODS The antimicrobial susceptibility of clinical isolates from(neonates) blood culture derived from sixteen hospitals in Hubei from 2000 to 2004,was retrospectively analyzed and tested by KirbyBauer(method).RESULTS A total of 1 019 strains were isolated from blood specimens,Gram-positive and Gram(-negative)(bacteria) accounted for 93% and 7% of these isolates,respectively.The main isolates were coagulase(-negative) staphylococci(CNS,79.8%),Enterococcus spp(7.0%),Staphylococcus aureus(SAU4.5%),Klebsiella spp(1.7%),Stenotrophomonas maltophilia(1.2%),and Escherichia coli(0.9%).71.3% CNS and 19.6% SAU were meticillin resistant,46.5% enterococci resistant to ampicillin and almost strains were susceptible to(vancomycin)(except E.gallinarum).ESBLs were detected in isolates of 56% E.coli and 35% K.pneumoniae.S.maltophilia was susceptible to trimethoprim(-sulfamethoxazole) and levofloxacin with resistance rate of 8.3% and 0%.In strains of other Gram-negative rods,resistance rate to imipenem,amikacin and fluoroquinolones were detected between 0% to 15%,and to cephalosporins Ⅰ-Ⅳ were between 20% to 70%.CONCLUSIONS Gram-positive cocci are important pathogens in neonatal sepsis,antimicrobials should be used on the result of(antimicrobial) susceptibility test.It is more important to reduce health care-associated(nosocomial) infections.

Objective To evaluate the level of serum cholesterol in patients with progressive gastric cancer and gastric ulcer before and after operation, and the relationship between the level of serum cholesterol and the clinical differential degree of progressive gastric cancer . Methods To measure the content of serum cholesterol in patients with progressive gastric cancer and gastric ulcer before operation and after operation 10 day. The size of tumor, infiltration, metastasis and the pattern of the operation were studied statistically. Results The level of serum cholesterol in group of progressive gastric cancer was significant lower than that of normal control group(P 0.05 ) in group A, but there was significant difference in group B after the operation(P

Objective: To evaluate biological materials tanned with a compound method for clinical performance of biovalves. Methods: The tissue calcium concentration was compared between biological materials tanned simply with amylic aldehyde and those compoundly tanned with amylic aldehyde, cation fat, chromium trioxide and glycerol. The histological morphology, the ultra-structure and tensile strength of the biological materials were tested and the content of hydroxyls in the materials was measured with the Fourier infrared spectrum detector. The prosthetic biological cardiac valves made of the materials were tested with an accelerated wearing device extracorporeally. Results: The tissue calcium concentration was lower in the compoundly tanned materials. In these materials, the collagenous fibers were dense and lined up in order. The cellular structure was maintained. The materials were pliable at the contracting temperature of 86℃ to 90℃. The tensile strength of the materials was 19.9 to 25.9 N/mm 2 and the extension rate was 43.4% to 46.0%. The peak of the hydroxyls decreased significantly at the wave length of 1741.11 cm -1 in the Fourier infrared spectrum. The swine aortic valve experienced 3.892?10 8 cycles in the accelerated wearing tests, and the bovine pericardial valve, 3.888?10 8 cycles. By estimation, the biovalves will last for about ten years. Conclusion: Compound tanning can increase firmness and softness of the materials and may play an important role in anticalcification of the biovalves.
