目的:探讨 L-selectin(L-选择素)和 ICAM-1(细胞间粘附分子-1)在乙型肝炎病毒感染造成肝功能损害过程中的作用。方法:定量检测42例乙型肝炎病人血清 HBV DNA 拷贝数、可溶性 L-选择素(sL-selectin)、可溶性细胞粘附分子-1(sICAM-1)及肝功能相关生化指标,并对结果进行统计分析。结果:22例 DNA 阴性和20例 DNA 阳性病人血清 sL-selectin 和 sICAM-1水平均明显高于对照组(P<0.05),但 DNA 阴性组和阳性组之间的 sL-selectin 和 sICAM-1水平均无显著差异(P>0.05);DNA 拷贝数与 sICAM-1水平呈负相关(r=-0.501,P<0.05);DNA 拷贝数与肝功能损害呈负相关;42例乙肝病人的 sL-selectin 和 sICAM-1水平均与肝功能损害呈不同程度的正相关。结论:L-selectin 和 ICAM-1均参与乙肝病毒感染后的肝功能损害过程,而血清中 sL-selectin 水平升高要早于 sICAM-1。

乙肝患者血清sICAM-1检测的临床意义

目的：探讨乙型肝炎患者血清可溶性细胞间粘附分子－1（sICAM-1)水平与肝损害的关系。方法：采用双抗体夹心ELISA法。检测20例正常人和67例HBV感染患者血清sICAM-1。结果：轻、中、重度慢性乙型肝炎（CH）患者及重型乙型肝炎（SH）早、中、晚期患者血清sICAM-1水平，均显著高于正常人；CH患者肝功能越差、其血清sICAM-1水平越高；SH患者肝衰竭越重，其血清sICAM-1水平反而越低。HBeAg阳性或HBV DNA阳性的乙肝患者血清sICAM-1水平与HBeAg阴性和HBV DNA阴性的乙肝患者相比差异无显著性。结论：在CH和SH早期，乙肝患者血清sICAM-1水平随着患者肝损害的加重而升高。重型肝炎患者血清sICAM-1水平随着患者肝衰竭的加重而降低，故sICAM-1可作为临床乙肝炎性活动和肝损害程度的监测指标。

Effect of 5-fluorouracil, mitoxantrone, methotrexate, and vincristine on the antibacterial activity of ceftriaxone, ceftazidime, cefotiam, piperacillin, and netilmicin

Using the checkerboard agar dilution technique, antibacterial activity and in vitro interactions of 4 antineoplastic agents and 5 antimicrobial drugs were examined against 56 strains of 7 bacterial species. 5-fluorouracil was found to inhibit all strains of Staphylococcus aureus and of Staphylococcus epidermidis at a concentration of 0.8 micrograms/ml or less. 84% of all gram-negative strains were inhibited synergistically when 5-fluorouracil was combined with beta-lactam antibiotics. Methotrexate and cefotiam were antagonistic in 42% of all combinations, especially when tested against Escherichia coli and Klebsiella pneumoniae.     

Susceptibilities of non-Pseudomonas aeruginosa gram-negative nonfermentative rods to ciprofloxacin, ofloxacin, levofloxacin, D-ofloxacin, sparfloxacin, ceftazidime, piperacillin, piperacillin-tazobactam, trimethoprim-sulfamethoxazole, and imipenem.

Agar dilution MICs of 10 agents against 410 non-Pseudomonas aeruginosa gram-negative nonfermentative rods were determined. MICs at which 50 and 90% of the isolates were inhibited, respectively, were as follows (in micrograms per milliliter): sparfloxacin, 0.5 and 8.0; levofloxacin, 1.0 and 8.0; ciprofloxacin, 2.0 and 32.0; ofloxacin, 2.0 and 32.0; D-ofloxacin, 32.0 and > 64.0; ceftazidime, 8.0 and 64.0; piperacillin with or without tazobactam, 16.0 and > 64.0; trimethoprim-sulfamethoxazole, 0.5 and > 64.0; imipenem, 2.0 and > 64.0. With the exception of those for Stenotrophomonas maltophilia, Burkholderia cepacia, and Alcaligenes faecalis-A. odorans, agar dilution MICs for all strains tested were within 1 dilution of inhibitory (bacteriostatic) levels as determined by time-kill methodology.     

Comparative ototoxicity of ribostamycin, dactimicin, dibekacin, kanamycin, amikacin, tobramycin, gentamicin, sisomicin and netilmicin in the inner ear of guinea pigs

Nine aminoglycoside antibiotics, ribostamycin (RSM), dactimicin (DAC), dibekacin (DKB), kanamycin (KM), amikacin (AMK), netilmicin (NTL), tobramycin (TOB), gentamicin (GM) and sisomicin (SISO) were administered intramuscularly to guinea pigs for 4 weeks, and ototoxicity and drug concentration in the inner ear fluid were determined. RSM and DAC showed the weakest ototoxicity against the cochlea and vestibular organs. AMK and KM were more toxic to cochlea than vestibular organs. DKB, TOM, GM and SISO were equally toxic to vestibular organs and cochlea. NTL was more toxic to vestibular organs than cochlea. As judged from the pinna reflex response and hair cell damage in the cochlea, the order of auditory toxicity was the following: SISO greater than GM greater than TOB greater than AMK greater than DKB greater than KM greater than NTL, DAC RSM, whereas the vestibular toxicity was in the following order: SISO greater than GM greater than DKB greater than TOB greater than NTL greater than AMK greater than KM greater than DAC, RSM. RSM, causing the weakest ototoxicity, showed a low drug concentration in the inner ear fluid, while GM, causing severe ototoxicity, showed the highest drug level under the same conditions.
