2-乙氧基乙醇急性染毒大鼠血清和睾丸某些抗氧化指标的变化

目的 观察2-乙氧基乙醇(2-Ethoxythanol,EE)急性染毒对SD大鼠血清和睾丸某些抗氧化指标的变化，探讨EE致睾丸损伤的可能机制。方法 选择健康雄性SD大鼠，体重180-220g。随机分为对照组、EE800、1600和3200mg／kg组4组，每组24只。采取一次性灌胃染毒。于灌胃后12、24、48和72h，将各组动物随机处死6只，留取动物血液、睾丸，制备血清和睾丸匀浆，测定血清和睾丸匀浆脂质过氧化物(LPO)水平、超氧化物歧化酶(SOD)活性、过氧化氢酶(CAT)活性，以及血清铜蓝蛋白(CP)活性。结果 与对照组比较，各染毒组睾／体比明显下降(P＜0.05)，睾丸匀浆LPO水平和血清CP活性增高。染毒12、24h，血清CAT、睾丸匀浆CAT和SOD活性增高，而染毒48、72h后，血清CAT、睾丸匀浆CAT和SOD活性显著降低(P＜0.05)。EE各染毒组血清LPO水平和SOD活性变化不明显。结论 推测EE毒作用的靶器官可能是睾丸，睾丸抗氧化功能的改变是EE致睾丸毒性的可能机制。     

激光上皮下角膜磨镶术后角膜上皮瓣临床观察

目的 观察及探讨准分子激光上皮下角膜磨镶术(Laser subepithel ialkeratomileusis，LASEK)后，角膜上皮瓣的成活率及其影响因素。方法 对行LASEK治疗的42例(80眼)于术后1、2、3天，1、2、3、4周在裂隙灯显微镜下进行角膜上皮瓣的观察。结果 34例(68眼)，角膜上皮瓣成活，成活占85％(68／80)；未成活8例(12眼)，未成活占15％(12／80)。结论 LASEK术后角膜上皮瓣成活率的高低，决定着LASEK的临床疗效，影响其成活的因素是多方面的。其中角膜上皮瓣边缘不整齐、破裂、对位不良、操作时间过长可能是其主要原因。     

A COMPARISON OF KETOPROFEN SR AND SULINDAC IN THE ELDERLY WITH RHEUMATOID ARTHRITIS

The elderly (age >65 years) are more vulnerable to side-effects induced by non-steroidal anti-inflammatory drugs (NSAIDs). We therefore performed a double-blind comparative study of ketoprofen SR and sulindac in patients with active rheumatoid arthritis, 65 years of age or older. Sulindac was chosen because of its possible renal sparing effects, and ketoprofen SR because of its short half life and sustained release delivery system. Eighty patients were entered. More patients withdrew from the study due to side-effects in the sulindac group; both treatment groups had a high incidence of side-effects during this study and during previous exposure to other NSAIDs, demonstrating that the elderly are susceptible to side-effects from NSAIDs.

Retardation of pain development: a case of recovery from congenital insensitivity to pain

Congenital analgesia is a rare genetic disorder. We report here that a 12-year-old boy was able to recover from congenital insensitivity to pain. Neurological examinations revealed that there was a 'stocking' distribution of pain decrement on the lower extremities under the patient's knee joints. Magnetic Resonance Imaging (MRI) of his brain showed gyrus thinning with sulcus widening at both sides of the parietal lobe. Southern blot hybridization probed with cDNAs of various opioid receptors did not detect any significant abnormality. Our results suggest that this rare case may not be genetically determined.     

Urban and Rural Differences in Health Insurance and Access to Care

This study considers differences in access to health care and insurance characteristics between residents of urban and rural areas. Data were collected from a telephone survey of 10,310 randomly selected households in Minnesota. Sub-samples of 400 group-insured, individually insured, intermittently insured, and uninsured people, were asked about access to health care. Those with group or individual insurance were also asked about the costs and characteristics of their insurance policies.
Rural areas had a higher proportion of uninsured and individually insured respondents than urban areas. Among those who purchased insurance through an employer, rural residents had fewer covered benefits than urban residents (5.1 vs 5.7, P < 0.01) and were more likely to have a deductible (80% versus 40%, P < 0.01). In spite of this, rural uninsured residents were more likely to have a regular source of care than urban residents (69% versus 51%, P < 0.01), and were less likely to have delayed care when they thought it was necessary (21% versus 32%, P<0.01). These differences were confirmed by multivariate analysis.
Rural residents with group insurance have higher out-of-pocket costs and fewer benefits. Uninsured rural residents may have better access to health care than their urban counterparts. Attempts to expand access to health care need to consider how the current structure of employment-based insurance creates inequities for individuals in rural areas as well as the burdens this structure may place on rural providers.
