吗啡的呼吸抑制作用与中枢胆碱能系统的关系

本文以兔呼吸频率、通气量和血气作为指标,观察到iv吗啡0.5～4.0mg/kg产生剂量依赖性呼吸抑制。icv匹鲁卡品2.5mg/kg能完全逆转这一抑制效应。icv 4—氨基吡啶(4—AP),1.5μg/kg兴奋呼吸,并使吗啡量效曲线右移。用利血平耗竭儿茶酚胺后,吗啡仍能抑制呼吸,4—AP可消除之。表明吗啡抑制呼吸与中枢胆碱能系统有关,且可能系它抑制Ach释放所致。     

老年冠心病患者低钾的临床观察

目的总结老年冠心病患者低钾的临床观察,提出预防措施。方法观察156例老年冠心病患者低钾的发生原因,临床表现,实验室资料,治疗转归等因素,进行分析总结。结果老年冠心病患者发生低钾有其自身发病特点,病因复杂,阳性症状少,治疗困难,恢复时间长,预后差。结论老年冠心病患者因其生理、病理特点较易发生低钾,且多发病隐蔽,表现不典型,容易漏诊,故要仔细观察病情,一旦发现要及时给予综合治疗。     

Effect of eucalyptus globulus oil on activation of nuclear factor-kappaB in THP-1 cells]

OBJECTIVE: To study the effect of eucalyptus globulus oil on the activity of nuclear factor-kappaB(NF-kappaB) in THP-1 cell line. METHODS: THP-1 cells were cultured with or without eucalyptus globulus oil at different concentrations (1, 10, 100 mg x L(-1), 30 min) before being stimulated with lipopolysaccharide (LPS, 1 mg x L(-1), 30 min). The location of NF-kappaB p65 subunit (NF-kappaB/p65) in THP-1 cells was detected by indirect immunofluorescence and laser scanning confocal microscope. The expression of NF-kappaB/p65 in nuclei was measured by Western-blot analysis. RESULT: The FITC-label NF-kappaB/p65 was mainly located in the nuclei after THP-1 cells were stimulated with LPS. Whereas, no fluorescence were seen in the nuclei of cells pretreated with eucalyptus globulus oil. This effect on NF-kappaB/p65 nuclear translocation was in a concentration dependent manner. CONCLUSION: Eucalyptus globulus oil inhibits the nuclear translocation of NF-kappaB induced by LPS in THP-1 cells.     

阴茎折断临床分析

目的 探讨阴茎折断伤的病因和诊治。方法 对2l例阴茎折断伤的临床资料进行回顾性分析。结果 致伤原因以粗暴性交13例，手淫5例，跌伤、撞击伤各l例，拒绝说明原因l例。B超确诊12例，阴茎海绵体造影确诊l例。12h内手术13例，超过12h手术3例，保守治疗5例。12h内手术组有2例发生阴茎白膜硬结，术后性功能正常；超过12h手术组和保守治疗组各有l例和2例并发阴茎硬结、阴茎成角畸形和勃起功能障碍。结论 阴茎折断致伤原因以粗暴性交和手淫为主；B超检查是诊断阴茎折断首选方法；早期手术能减少其并发症的发生；术中采用纵行小切口容易准确找到白膜破裂位置，且创伤小，适于临床应用。     

金黄色葡萄球菌儿童株耐药性分析

目的 了解儿童中金黄色葡萄球菌所致疾病的分布及其对常用抗生素的敏感情况。方法 收集连续12个月的临床致病株，根据菌落形态、革兰染色特点和乳胶凝集实验对金黄色葡萄球菌进行初步筛选，用细菌自动鉴定系统Vitek GPI卡和GPS-101卡进行菌株鉴定和药敏试验。结果 分离到金黄色葡萄球菌145株，其中来自呼吸道感染患儿痰或咽拭子培养109株，占75．17％，来自血培养16株，占11．03％，来自脓液、阴道分泌物培养分别占6．21％和5．51％。药敏试验显示92．4l％的菌株产生β-内酰胺酶，96．55％的菌株对青霉素耐药，但耐苯唑西林的仅占6．21％。99．31％和100％的菌株分别对利福平和万古霉素敏感，对环丙沙星、阿莫西林／棒酸、头孢唑林、复方新诺明、庆大霉素和林可霉素的敏感率分别为95．86％、93．10％、92．41％、86．21％、84．83％和80．69％，37．93％的菌株对红霉素耐药。结论金黄色葡萄球菌常引起儿童呼吸道感染，对苯唑西林的耐药率低．该药仍是治疗小儿会黄色葡萄球菌感染的有效药物。     

现代化医院呼唤现代服务模式

当前我们正在向建设基本现代化医院迈进,在注意硬件建设的同时,不要忽略软件建设。硬件建设需要大量投入,较易见成果;而后者无需大量财力投入,只需转变医院人的思想观念,就能使医院明显改观。

Anatomic and spiral computed tomographic study of the genial tubercles for genioglossus advancement.

OBJECTIVE: To measure and compare Chinese mandibular genial tubercles measured anatomically and with computed tomography (CT). STUDY DESIGN AND SETTING: Spiral CT scans were taken of 40 adult human skulls; the superior genial spines were measured using anatomic and CT methods. RESULTS: The height and width of the superior genial spines, mandible thickness, and distance from the menton to the inferior and superior margins of the superior genial spines were 5.82 +/- 0.71, 6.98 +/- 1.35, 11.95 +/- 1.59, 11.08 +/- 2.05, and 16.91 +/- 2.30 mm from anatomic measurements and 6.17 +/- 0.71, 7.01 +/- 1.13, 12.19 +/- 1.64, 10.41 +/- 1.55, and 15.73 +/- 2.12 mm using spiral CT, respectively. The anatomic and CT measurements were correlated. CONCLUSION: Spiral CT of the genial tubercles can help locate the osteotomy in genioglossus advancement. SIGNIFICANCE: This study acquired reference data on Chinese genial tubercles demonstrating that CT measurements of the genial tubercles reflect their anatomy, which should allow accurately locate the osteotomy.
