中西医结合要为妇女生殖健康创新页

45年来,复旦大学妇产科医院在中西医结合临床及科研方面取得了可喜的成就.针刺促排卵的研究,通过观察血雌激素和中枢β-内啡肽(β-EP)的关系,提出了针刺通过耗竭中枢β-EP而促排卵的新认识,认为针刺促排卵的主要适应症是青春期月经失调,并将针刺成功地应用于治疗神经性厌食;补肾化痰的俞氏温补方治疗多囊卵巢综合征(polycystic ovary syndrome, PCOS)被证实是通过提高血促卵泡激素(follicle stimulating hormone, FSH)并诱发排卵而起作用;益肾化瘀的天癸方是通过降低患者及动物模型的雄激素和胰岛素,引起以中枢阿片促黑激素皮质素原、神经肽Y和瘦素受体为主的神经-内分泌-代谢网络调节而发挥促排卵和减肥作用,对高胰岛素型PCOS有良效,并在研究中提出了对PCOS分类的新设想;益肾清火的更年春通过提高中枢与周围组织的雌激素受体及其mRNA表达来调节围绝经期妇女的神经-内分泌-免疫-代谢网络而获优越疗效.这些研究表明,疾病是外环境影响下患者生命网络的某些主脉失调所致,而且亚健康状态的妇女具有初步网络失控的现象,中西医结合将为女性生殖医学研究找到捷径,调控生命网络是防病治病的主要思路.

骨水泥和种植体同期植入修复颌骨和牙列缺损的实验研究

目的：探讨高分子材料和种植体同期植入缺损区进行同步骨缺损修复和牙列缺损修复的可行性。方法：以4只杂种狗为研究对象，制备下颌骨长约2．5cm的缺损的动物模型(保留下颌骨下缘)，将骨水泥(聚甲基丙烯酸酯)植入骨缺损，同时将牙种植体植入骨水泥中并调整长轴方向，立即关闭术创。至术后3个月摄X线片，然后处死动物，局部巨检以了解骨水泥同骨组织的结合情况，并制备骨组织切片进行苏木精一伊红染色和甲苯胺蓝染色，以了解植入材料周边骨的生长情况及其对植入材料的反应。结果：术后3个月X线检查见骨缺损区充满骨水泥，骨水泥周边的骨小梁清晰，未见骨吸收或炎症表现，形成良好的骨-骨水泥界面，种植体则依赖其表面的螺纹结构与骨水泥间紧密的机械性嵌合而牢固的成为一体，植入的骨水泥块与周边天然骨结合紧密，无松动现象。植入材料周边局部脱钙骨的苏木精-伊红染色和甲苯胺蓝染色见骨结构正常，同时骨-骨水泥界有新骨形成。结论：骨水泥作为颌骨修复替代材料同期植入种植体是可行的。     

女性运动试验后QTc与ST的对比分析

作者测量100例妇女心电图运动试验后即刻QTc间期。冠心病组50例运动后即刻QTc间期比静息时明显延长(P<0.001),比正常配对组50例则明显缩短(P<0.001)。以QTc间期延长≥0.01秒力阳性指标,与ST段压低比较,其敏感性可从42％提高至70％,特异性从66％提高至76％;如综合QTc间期与ST段标准加以判断时,可使敏感性、特异性分别增至74％、88％。     

Hyperthyroidism associated with papilloedema and pyramidal tract involvement

Summary In a patient with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes [MELAS] who had normal mitochondrial enzyme activity, high doses of coenzyme Q₁₀ (CoQ) were administered. Clinical improvement with decreased serum lactate and pyruvate levels was observed. Though the mechanism of action of CoQ is not known, a trial is worthwhile in patients with MELAS.     

双腔右心室(附四例报告)

本文对我院1983～1985年经手术证实的4例双腔右心室病例,进行了分析讨论。本病除右心导管检查发现肺动脉与右心室有压力阶差移行曲线、右心造影时心腔内显示充盈缺损、超声心动图等检查有助于诊断外,X线心脏平片、心电图、临床症状、体征均无特异性的诊断价值。认为,由于本病多合并室缺,因此对室缺修补时,应常规探查右心室腔,以免漏诊。另外,对本病与法乐氏四联症的鉴别作了较详细的讨论。

歼击机飞行员改装体检脊柱病症的医学鉴定

目的对近几年来我院改装体检歼击机飞行员脊柱病症健康鉴定进行归纳总结。方法收集分析了261例歼击机飞行员体检和X线、CT的影像诊断资料,并对因脊柱病症体检不合格资料进行统计学分析。结果歼击机飞行员体检中,脊柱影像诊断中以腰椎间盘突出(49例)最多,但多数没有相应的临床症状,有20例因脊柱病症不合格,其中腰椎双侧峡部裂伴Ⅰ°滑脱9例,占不合格总数的45%,是不合格的主要原因。结论外科体检中应该重点加强对脊柱的检查,影像诊断应结合症状和脊柱功能作出鉴定,必要时应作随访观察。     

Liver regeneration in acute severe liver impairment: a clinicopathological correlation study.

BACKGROUND: Although normally quiescent, the adult mammalian liver possesses a great capacity to regenerate after different types of injury. Major players in the regeneration process are mature residual cells, including hepatocytes, cholangiocytes and stromal cells. However, if the regenerative capacity of mature cells is impaired, hepatic progenitor cells (HPCs) are activated and expand into the liver parenchyma. Upon transit amplification, the progenitor cells generate new hepatocytes and biliary cells to restore liver homeostasis. AIMS/METHODS: To study the relationship between different histopathological parameters as well as their correlations with clinical parameters and outcome, we examined liver specimens from 74 patients with acute or subacute severe liver impairment by immunohistochemistry for CK7/CK19 (evaluation of HPCs activation/differentiation), Mib1(Ki 67)/P21 (evaluation of proliferative activity/proliferation arrest of hepatocytes) and hematoxylin and eosin (evaluation of hepatocyte loss). RESULTS: Of the 74 patients, 32% survived without transplantation, 14% died without transplantation and 54% were transplanted. Our results show that a threshold of 50% loss of hepatocytes, associated with significant decrease in the proliferative activity of remaining mature hepatocytes, is needed for extensive hepatic progenitor cell activation. Such activation is a sign of disease severity and occurs early (within 1 week) in the disease course. However, development of intermediate hepatocytes, suggesting HPCs differentiation towards mature hepatocytes, takes at least 1 week's time. We found a positive correlation between histopathological parameters (percentage hepatocyte loss, number of proliferating hepatocytes and number of HPCs) and clinical parameters of liver impairment such as model for end stage liver diseases (MELD). Surviving patients compared with those who either died or were transplanted had significantly less hepatocyte loss, less HPCs activation and more mature hepatocyte proliferative activity. Hepatocyte proliferative activity and degree of hepatocyte loss were the most important independent histopathological parameters in predicting outcome. CONCLUSION: Liver biopsy can provide important additional information in a patient with severe acute liver impairment.
