血清铁和铁蛋白与肝病患者肝纤维化指标的关系

OBJECTIVE: To study the relationship of serum iron and ferritin with the indicators for hepatic fibrosis and hepatic iron overload. METHODS: Liver tissue specimens were obtained from 41 patients with benign (16) or malignant (25) liver diseases by 1 second liver biopsy, and routine microscopic examination was performed after haematoxylin-eosin (HE) and Perl's Prussian staining. Atomic absorption spectrum, radioimmunoassay and enzyme-linked immunosorbent assay were respectively employed to examine the serum levels of iron, ferritin, hyaluronic acid, laminin, human procollagen type , and collagen type . RESULTS: Between patients with benign and malignant liver diseases, significant differences were found in the serum ferritin levels (P < 0.05), but not in serum iron levels (P > 0.05). It was also noted that the levels of the indicators for hepatic fibrosis in patients with benign and early-stage malignant diseases varied significantly from the levels in normal subjects, but these differences were not observed between normal subjects and patients with end-stage hepatic malignancies. Serum iron and ferritin were found to be associated with serum laminin levels (serum iron: r=0.439, P=0.031; serum ferritin: r=0.476, P=0.016), and no iron granules detected in the tissue specimens of hepatocellular carcinoma. CONCLUSIONS: Most of the patients with hepatocellular carcinoma have elevated serum ferritin levels. The serum levels of iron and ferritin are statistically correlated with serum laminin level. Obvious reduction of iron content is typical of hepatic malignant tissues in comparison with the benign tissues, and the reduction in the levels of the indicators for hepatic fibrosis might involve the inhibition of collagen synthesis in the tumor tissues from patients with end-stage hepatocellular carcinoma. Most of the cases of alcoholic fatty liver are complicated by liver iron overload, often marked by serum iron and ferritin levels.     

前列腺癌激素治疗中的几个热点问题

前列腺癌激素治疗是由Huggins等在1941年开创的。此后，在临床应用中体现出的显著疗效使得这种治疗直至今日仍被认为是晚期前列腺癌的最有效治疗方法。但是，激素治疗是否仅仅适用于晚期患者的治疗呢?大量的临床实践与文献报告已经揭示，在一些其他脏器的实质性肿瘤的治疗中，术前应用化疗的确能够缩小肿瘤以提高肿瘤的完整切除率，而术后的     

可控制性卵巢刺激治疗中促性腺激素释放激素激动剂降调节与卵巢过度抑制

基于促性腺激素释放激素激动剂(GnRH-a)短时给药对垂体的激发作用引起血清黄体生成素(LH)和卵泡刺激素(FSH)升高有利于增加卵泡募集,而长期给药导致垂体局部受体脱敏与消耗而有效地抑制排卵前LH峰出现和降低卵泡晚期血清LH水平,从而减少卵泡过早黄素化和取消周期、改善卵子质量     

狼疮性肾炎血清免疫球蛋白与补体水平变化

宿主诱导的ALT/AST反跳对慢性乙肝治疗应答的影响

对255例HBeAg阳性慢性乙肝患者给予干扰素α-2b 5 mIU/次,隔日1次,治疗48周。治疗过程中出现ALT/AST反跳65例,其中宿主诱导的ALT/AST反跳24例,病毒诱导的ALT/AST反跳25例,宿主诱导的ALT/AST反跳患者HBeAg血清转换率明显高于病毒诱导的ALT/AST反跳患者;ALT/AST反跳与治疗前ALT/AST水平无明显相关性;治疗前HBV DNA≥105Copies/ml者ALT/AST反跳率高于<105Copies/ml者。提示宿主诱导的ALT/AST反跳可能预测将来有较高的HBeAg血清转换率。     

精液FSH、LH、PRL和T水平与精子质量关系的研究

目的探讨人精液中性激素水平与精子质量的关系。方法参照WHO标准方法,进行精子密度、活动率检测,按不同密度和活动率分为4个组。采用ELISA法分析FSH、LH、PRL和T水平。用脱氧核苷酸末端转移酶(TdT)介导的缺口末端标记(TUNEL)法检测生殖细胞的凋亡。结果68例不育者精子密度和活动率随精液性激素水平减少而下降,呈显著性正相关(P均<0.01),生育组精液中FSH、LH、PRL和T水平分别为(1.73±0.15)mIU/ml、(2.28±0.21)mIU/ml、(6.44±0.30)ng/ml、(1.95±0.11)ng/ml,生殖细胞凋亡率为(4.71±1.23)%,与不育组(1.35±0.18)mIU/ml、(1.86±0.32)mIU/ml、(5.96±0.31)ng/ml、(1.55±0.13)ng/ml和(19.36±2.04)%相比有显著性差异(P<0.01)。不育组FSH、LH、PRL、T水平与生殖细胞的凋亡率呈显著性负相关(r分别为-0.89、-0.94、-0.91、-0.98)。结论精液低性激素水平可使睾丸生殖细胞凋亡率增加,精子密度和活率下降而致男性不育。

闭合性颅脑损伤患者心肌酶谱改变的临床意义

脑-心综合征（cerebral-cardiac syndrome，CCS）特指急性脑循环障碍（包括脑出血、脑缺血和蛛网膜下腔出血）及急性颅脑损伤而引起的类似心肌缺血、心律失常、急性心肌梗死或心力衰竭的一组症状。急性脑损伤条件下，心脏病变发生率高。影响其预后。临床上有报道。严重颅脑外伤患者有心肌酶谱改变，但分析闭合性颅脑损伤患者血清心肌酶谱变化者甚少。本文对60例闭合性颅脑损伤患者血清心肌酶进行测定。现分析如下。
