急性脑梗死血清C-反应蛋白的临床分析

目的观察急性脑梗死患者血清CRP在发病中的作用及临床意义。方法采用免疫比浊法对60例急性脑梗死患者的血清CRP水平进行动态观察（病程第1．7及14天），并与45例健康人进行比较。结果急性脑梗死患者血清CRP从病程第1天即升高（P〈0．01），至第7天达高峰，以后降低；重型患者明显高于轻、中型患者。结论血清CRP可能在急性脑梗死的发生、发展中起一定作用，并与病情严重程度呈正相关。     

Renal Allograft Biopsies with Borderline Changes: Predictive Factors of Clinical Outcome

The clinical outcome and appropriate management for patients showing 'borderline changes' on allograft biopsy after renal transplantation is still controversial. In an attempt to identify predictive factors of clinical outcome of patients with such lesions, we reviewed the clinical course of 91 patients with borderline changes. Multivariate analysis revealed significant and independent effects of histological stage (i + t < or = or > 2) and time to borderline changes (< or = or > 3 months after transplant) on serum creatinine levels at 1 year from borderline changes episodes (respectively, p = 0.04 and p = 0.02) and only a significant effect of time to borderline changes on serum creatinine levels at 2 years (p = 0.005). Renal function at 1 year and 2 years as 5- and 8-year graft survival were not significantly different in the group of patients treated with antirejection therapy (T group, n = 49) compared with the untreated group (UT group, n = 42). This study strongly suggests that borderline changes with histological score (i + t) > 2 and late episodes of borderline changes should be considered to be of poor prognosis.

Pulmonary Lophomonas blattarum infection in patients with kidney allograft transplantation

The aim of the study was to analyse the clinical manifestation and management of pulmonary Lophomonas blattarum infection in four allograft transplantation recipients retrospectively. Four patients with pulmonary L. blattarum infection were diagnosed by using Fiberoptic bronchoscopy (FOB) and bronchoalveolar lavage (BAL) examination. Their clinical manifestation and management are summarized. Four cases of pulmonary L. blattarum were found during the period from the second month to the third month after transplantation. Concurring infection by other pathogens was found in three of them. Common initial symptoms included fever (>38 degrees C) without cough and breathlessness. Lower lobe shadowing could be found on chest X-ray. Body temperature decreased to the normal range in three patients and to 37.5 degrees C in the other one, after intravenous injection of metronidazole and tapering immunosuppressant. Radiological examination confirmed improved health condition of the patients afterwards. Two patients received repeated FOB and only dead L. blattarum was found. Pulmonary L. blattarum infection in allograft transplant recipients carry relatively obscure initial symptoms. Possible L. blattarum infection needs to be screened in post-transplantation pulmonary infection patients with similar symptoms, especially in those who respond poorly to anti-infection treatment. Microscopic examination of BAL fluid can help to identify pulmonary L. blattarum infection and metronidazole is an ideal treatment choice.     

血管内皮生长因子及炎性因子在油酸性犬急性呼吸窘迫综合征中的变化

目的探讨油酸性急性呼吸窘迫综合征（ARDS）beagle犬血浆及肺泡灌洗液血管内皮生长因子（VEGF）、可溶性细胞间黏附分子-1（ICAM-1）、白细胞介素-8（IL-8）、肿瘤坏死因子-α（TNF—α）水平的改变。方法12只英国纯种beagle犬，静脉注射油酸0．15mL／kg，在注射油酸前、后1h，出现ARDS的典型表现时，抽血测VEGF、sICAM-1、IL-8、TNF—α，并对此时相作肺泡灌洗液VEGF、sICAM—1、IL-8、TNF-α的测定。结果beagle犬静脉注射油酸后1h血浆TNF—α升高（P〈0．05），血浆反肺泡灌洗液IL8、sICAM-1和VEGF在1h较油酸前没有明显变化（P〉0．05），beagle犬油酸型ARDS模型建立后血浆及肺泡灌洗液VECF、sICAM-1、IL-8、TNF—α均显著高于建模前（P〈0．05）。结论VEGF、sICAM-1、IL-8、TNF～α在beagle犬油酸型ARDS发生发展过程中可能均起重要作用，其水平的高低可能与ARDS严重程度及预后有关。     

严重慢性阻塞性肺疾病患者食管切除术围手术期并发症及处理

目的 探讨重度慢性阻塞性肺疾病简称慢阻肺病人食管切除术围手术期常见并发症及其处理。方法 45例重度慢阻肺的病人在全麻联合硬膜外阻滞下进行开胸食管切除手术，围手术期处理包括术前戒烟、胸部理疗、预防和控制呼吸道感染、解痉化痰、呼吸功能锻炼、营养支持和氧疗；术后硬膜外镇痛、早期锻炼、保持呼吸道通畅，部分病人予以呼吸支持。结果 术中3例出现低氧血症。术后所有病人PaO2均有不同程度的下降，6例出现肺部感染，6例行纤维支气管镜吸痰，2例通过气管插管给予呼吸机支持，2例行气管切开术，1例酸碱平衡紊乱使用盐酸精氨酸治疗。所有病人均痊愈出院。结论 重度慢阻肺病人并非开胸食管切除手术的绝对禁忌证，积极的术前准备和严格的术后管理可减少和控制术后急性发作，有助于确保此类病人的围手术期安全和康复。     

Congenital quadricuspid aortic valve with tetralogy of Fallot and pulmonary atresia

We report the case of a 4-year-old girl who had quadricuspid aortic valve regurgitation with tetralogy of Fallot and pulmonary atresia. This combination is very uncommon. Aortic valve replacement was performed successfully due to aortic regurgitation which had progressed one year after the total repair. The dilated aortic annulus plus quadricuspid aortic valve may result in progressive aortic regurgitation for a short period.
