跻身红尘

一袭蓑衣，一根鱼竿，临岸静坐。庄子参破世间万物．宁愿静守一泓静水．坐看风云变幻． 一垄田．一把犁．茅屋菊花。陶渊明脱离浊淖，采菊东篱得见南山．行于世俗之外。     

亚甲蓝甘油合剂封闭治疗三叉神经痛108例

目的观察亚甲蓝甘油合剂封闭治疗三叉神经痛的临床疗效并探讨其治疗机制。方法按国际头面痛学会分类委员会确定的诊断标准,108例原发性三叉神经患者随机分为两组:A组为亚甲蓝甘油合剂组(n=54),B组为单纯甘油合剂组(n=54);采用徐贵印推荐的三维测角穿刺半月神经节进行封闭治疗,对治疗后1周、3个月和2年分别进行疗效评判和随访观察。结果两组治疗后1周、3个月优良率比较差异无统计学意义(P>0.05),两年后优良率比较差异有统计学意义(P<0.05);两组并发症没有明显差异,2例出现视力下降,3例因解剖变异未能穿刺成功,仅在卵圆孔周围进行了注射,外加眶下孔以及骸孔封闭。结论亚甲蓝甘油合剂用于治疗三叉神经痛远期疗效优于单纯甘油合剂,且亚甲蓝对神经未见明显损害(经2年随访)。     

92例重型肝炎并发自发性细菌性腹膜炎的诊断与治疗

目的探讨重型肝炎并发自发性细菌性腹膜炎(SBP)的诊断和抗生素使用。方法回顾性分析2002年7月~2005年6月间收治的92例并发SBP的重型肝炎患者的临床资料。结果92例患者中,发热72例(78.26%),腹胀85例(92.39%),腹痛38例(41.30%),反跳痛35例(38.04%),83例(90.21%)外周血中性粒细胞(PMN)分类≥0.75,40例(45.98%)腹水PMN计数≥250个/mm3,79例(90.80%)腹水PMN比值≥0.50,11例(12.00%)腹水细菌培养阳性,共分离出细菌17株,G-杆菌占52.9%(9/17),其对头孢曲松、头孢哌酮、头孢他啶、左旋氧氟沙星及泰能敏感,对丁胺卡那、氧哌嗪青霉素敏感性较低。临床治疗显示,联合使用头孢他啶和甲硝唑效果较好,并较少出现继发真菌感染。结论重型肝炎并发SBP患者的临床表现不典型,腹水培养阳性率低,外周血和腹水PMN比值是诊断SBP比较可靠的参数。治疗SBP,可首选二联使用头孢他啶与甲硝唑,疗程约10~14日。     

Severe community-acquired pneumonia due to Legionella pneumophila Serogroup 6.

Legionella pneumophila is a common cause of sporadic community-acquired pneumonia, but culture-proven legionellosis is rarely diagnosed. There is no laboratory test for Legionnaires' disease that can detect all patients with the disease. Culture is the standard diagnostic method and should be initiated as soon as possible in suspected cases. We describe a rare case of community-acquired pneumonia caused by L. pneumophila serogroup 6. A 77-year-old man was admitted to a tertiary care hospital because of high fever, productive cough, and progressive dyspnea. Chest radiography showed bilateral pneumonia, which led to respiratory failure necessitating mechanical ventilatory support. Despite antibiotic therapy, his condition continued to deteriorate and acute renal failure also developed. Urine was negative for L. pneumophila. Culture of the sputum yielded L. pneumophila serogroup 6, although there was no elevation of the serum antibody titer. Pneumonia resolved gradually and he was extubated after treatment with levofloxacin followed by erythromycin. L. pneumophila other than serogroup 1 should be included in the differential diagnosis of patients with suspected atypical community-acquired pneumonia.     

二甲双胍对多囊卵巢综合征患者胰岛素样生长因子-1的影响

目的探讨二甲双胍对多囊卵巢综合征（PCOS）患者血清胰岛素样生长因子-1（IGF-1）及胰岛素样生长因子结合蛋白-1（IGFBP-1）水平的影响及其作用机制，明确二甲双胍治疗的临床效果。方法2002年1—11月对山西医科大学第二医院24例PCOS患者给予二甲双胍500mg，一日3次，8～24周治疗，比较治疗前后血清IGF-1、IGFBP-1、空腹胰岛素及睾酮水平，并对月经恢复、排卵、妊娠情况进行分析。结果二甲双胍可降低血清空腹胰岛素及睾酮水平，能显著升高IGFBP-1水平，治疗前后血清IGF—1水平差异无显著性。单纯二甲双胍治疗后月经恢复率为41．67％（10／24）；自然排卵率为25．00％（6／24），自然妊娠率为12．50％（3／24）。二甲双胍加促排卵治疗共18个周期，排卵周期率66．67％（12／18），妊娠周期率为11．11％（2／18）。结论二甲双胍可以降低血清空腹胰岛素及睾酮水平，增高IGFBP-1水平，可以改善卵泡微环境，有助于月经恢复，提高促排卵和妊娠率．是治疗PCOS的重要手段。     

Non-invasive Assessment of Coronary Flow Velocity Reserve: A New Method Using Transthoracic Doppler Echocardiography

Coronary flow reserve (CFR) has been used toassess coronary microcirculation and epicardial coro-nary stenoses[1— 3 ] . CFR is defined as the ratio ofcoronary flow under maximal coronary vasodilatationto coronary flow under resting conditions[4 ] .Whenthe cross- sectional area of epicardial coronary arteriesis constant,coronary flow velocity (CFV) ratios areequal to volume flow ratios.The most common method used clinically formeasuring CFVR is intracoronary Doppler flow(ICD) analysis re…

表皮生长因子对牛眼小梁细胞c—fos基因表达的诱导

目的研究表皮生长因子（ｅｐｉｄｅｒｍａｌｇｒｏｗｔｈｆａｃｔｏｒ，ＥＧＦ）对小梁细胞的作用。方法应用分子杂交技术研究ＥＧＦ对体外培养的牛眼小梁细胞ｃ－ｆｏｓ基因表达的诱导和３Ｈ胸腺核苷酸（３Ｈ－ｔｈｙｍｉｄｉｎｅｉｎｃｏｒｐａｒａｔｉｏｎ，３Ｈ－ＴｄＲ）掺入法观察细胞ＤＮＡ的合成。结果小梁细胞的３Ｈ－ＴｄＲ掺入率随着ＥＧＦ浓度不同而变化，浓度为２０～１５０ｎｇ／ｍｌ时，细胞掺入率随浓度增加升高（Ｐ＜０．０１）。与对照组相比，ＥＧＦ刺激停止生长的小梁细胞０．５小时后，ｃ－ｆｏｓ基因开始表达，１小时后达高峰，至２小时后消失。不同浓度ＥＧＦ刺激小梁细胞１小时后，ｃ－ｆｏｓ基因表达呈浓度依赖性。结论实验结果表明ＥＧＦ刺激小梁细胞增殖或进入生长状态，可能与ｃ－ｆｏｓ基因产物的信号传递作用有关。
