Trace element status (Se, Zn, Cu) in heart failure.

OBJECTIVE: It has been speculated that trace elements may play a role in the pathogenesis of heart failure. In the present study, we aimed to assess serum concentrations of selenium (Se), zinc (Zn) and copper (Cu) in patients with heart failure (HF) and to compare idiopathic dilated cardiomyopathy (IDCM) and ischemic cardiomyopathy (ICM) patients with healthy controls. METHODS: This study population included 54 HF patients (26 IDCM patients and 28 ICM patients) and 30 healthy subjects. Serum levels of selenium, zinc, and copper were assessed by atomic absorption spectrophotometry method. RESULTS: Serum concentrations of Se and Zn in HF patients were significantly lower than in healthy controls (p=0.000 and p<0.01, respectively). However, serum Cu concentrations in these patients were significantly higher than in controls (p=0.000). There were no significant difference in the trace elements status between IDCM and ICM patients (p>0.05 for all parameters). Relationships of the serum trace element concentrations studied with echocardiographic and hemodynamic parameters were not statistically significant. CONCLUSION: Our study showed that heart failure is associated with lower Se and Zn concentrations, and higher Cu concentration, and serum Se, Zn and Cu element profiles were similar in IDCM and ICM.

Serum matrix metalloproteinase-3 (stromelysin-1) concentration in patients with chronic liver disease.

BACKGROUND/AIMS: Matrix metalloproteinase (MMP)-3 plays an important role in extracellular matrix degradation, because of its broad substrate specificity and its activation of other proMMPs. Our aims in the present study were to determine whether the measurement of serum MMP-3 is clinically useful for assessing ongoing liver fibrolysis in patients with chronic liver disease. METHODS: We measured the serum MMP-3 concentrations with a sandwich enzyme immunoassay in 58 patients with chronic hepatitis, 22 patients with liver cirrhosis, 45 patients with hepatocellular carcinoma and 124 healthy individuals. The liver MMP-3 content was also measured in autopsied livers. RESULTS: Among the healthy controls, the serum levels of MMP-3 were about 2-fold higher in the males than in the females. In this study, the serum MMP-3 results of mainly the male group were analyzed because of the large number of male subjects. Compared to the control level, the mean serum MMP-3 concentration was 55% lower in chronic hepatitis, 53% lower in liver cirrhosis and 46% lower in hepatocellular carcinoma. There was no significant difference in the serum MMP-3 levels among the chronic hepatitis, liver cirrhosis and hepatocellular carcinoma groups. The serum MMP-3 levels were not related to the histological degree of necroinflammation or of liver fibrosis in the patients with chronic hepatitis. No significant difference in serum MMP-3 levels was observed among three Child's subgroups in the group of cirrhotic patients. In the group of patients with hepatocellular carcinoma, the serum MMP-3 levels were not related to the severity of liver function, the HCC tumor size, or the histological differentiation. The serum MMP-3 level was not correlated with serum markers for connective tissue turnover, i.e. procollagen type III peptide, 7S fragment of type IV collagen, hyaluronan and tissue inhibitor of metalloproteinase-1 in the patients with chronic liver disease or hepatocellular carcinoma. CONCLUSIONS: The measurement of serum MMP-3 is of little use for assessing fibrolysis in chronically diseased livers.

乙型肝炎肝硬化骨代谢异常的临床研究

目的探讨乙型肝炎肝硬化患者骨代谢异常的发病机制。方法用NM-300单光子骨密度测量系统检测61例乙型肝炎肝硬化患者的骨密度，空腹抽血检测血清钙调节激素：1，25二羟维生素D3[1，25（OH）2D3]、甲状旁腺素（PTH）、降钙素（CT）、骨钙素（BGP），白细胞介素-1β（IL-1β）、白细胞介素-6（IL-6）、肿瘤坏死因子α（TNF α）、尿骨胶原交联（Corsslaps），并与30名健康者对照。结果肝硬化组尺骨密度、桡骨密度、尺桡密度均较对照组明显降低。肝硬化组血清1，25（OH）2D3、BGP水平较对照组明显降低，其中骨质疏松（OP）组较无骨质疏松（NOP）组降低更明显，尿Crosslaps水平肝硬化组较对照组明显升高，其中OP组较NOP升高更明显。血清1，25（OH）2D3、BGP水平与尺桡密度呈正相关。OP组尿Crosslaps水平与尺桡密度呈负相关，而NOP组尿Crosslaps水平与尺桡密度无相关关系。肝硬化组血清IL-1β、IL-6、TNF α水平较对照组明显升高。血清IL-1β、IL-6、TNF α水平肝硬化OP组较NOP组显著升高。肝硬化组IL-1β、IL-6、TNF α水平与尺桡密度呈负相关，其中OP组较NOP组相关性更明显。结论乙型肝炎肝硬化患者存在着骨形成减少和骨破坏过多两种因素，从而引起肝性骨病，在骨形成减弱的过程中1，25（OH）2D3起了主要作用，在骨吸收增强的过程中IL-1β、IL-6、TNF α起到了重要的作用。     

Levels of serum hyaluronic acid, TNF-alpha and IL-8 in patients with nonalcoholic steatohepatitis

BACKGROUND/AIMS: Nonalcoholic steatohepatitis (NASH) is a common cause of liver disease that comprises a wide spectrum of liver damage, ranging from simple steatosis to steatohepatitis. The aim of this study is to investigate serum hyaluronic acid (HA), TNF-alpha, IL-8 levels in patients with non-alcoholic steatohepatitis and to assess their potential value as a noninvasive marker for the severity of histopathology. METHODOLOGY: Twenty-eight patients with biopsy-proven NASH, 14 patients with cirrhosis and 15 healthy controls were studied. Histopathological findings were graded and staged. HA, IL-8, TNF-levels were determined using by ELISA test RESULTS: Serum HA levels in patients with NASH were significantly higher than in the healthy control group (P < 0.05). However, the levels in patients with cirrhosis were markedly higher than in patients with NASH and healthy controls (P < 0.001). Serum TNF-alpha levels were significantly higher in patients with NASH and cirrhosis than in healthy controls (P < 0.05). Serum IL-8 levels in patients with NASH (P < 0.001) and cirrhosis (P < 0.05) were significantly higher than in the healthy control group. There was no correlation between serum HA and IL-8, TNF-alpha, ALT and AST levels. Serum HA level in patients with NASH was 187.26 +/- 139.21 and 143.49 +/- 93.14 in stage in stage 2-3 and in stage 0-1, respectively, but the difference was not significant (P > 0.05). CONCLUSIONS: In conclusion, serum HA, IL-8 and TNF-alpha levels increased in patients with NASH. Their relation with the severity of histopathology is not significant. Serum HA levels may be a useful marker to monitor the conversion from fibrosis to cirrhosis. Further studies are needed on this topic.     

Zinc and liver cirrhosis

We have measured zinc levels in serum and urine of healthy controls, patients with liver cirrhosis and patients with cirrhosis and hepatic cancer. In patients with ascitic fluid, we also measured zinc, total protein, albumin and alpha 2-globulin. Basal measurements were performed in blood drawn at 8.00, before the intravenous administration of 8 mg zinc in the form of zinc sulphate. Serum levels were measured at various intervals to a total time of 24 h after overload, and total urine was collected for zinc determinations 24 h before and 24 h after overload. Under basal conditions, cirrhotic patients had lower serum levels and higher rates of urinary excretion of zinc than controls. After overload, blood levels of zinc fell more rapidly in cirrhotic patients than in controls, the former group showing no concomitant rise in urinary zinc excretion, thus suggesting an organic deficit in this trace element. In ascitic fluid, the concentration of zinc was positively correlated with protein content.

目的 探讨应用血清高尔基蛋白体73（GP73）、甲胎蛋白异质体3（AFP-L3）、AFP和α-L-岩藻糖苷酶（AFU）水平诊断原发性肝癌（PLC）患者的效能。方法 2015年1月~2017年3月我院诊治的PLC患者261例,乙型肝炎肝硬化患者201例,慢性乙型肝炎患者238例和体检健康人200例,采用酶联免疫吸附试验法检测血清GP73水平,采用亲和吸附离心管法检测血清AFP-L3,采用全自动化学发光仪检测血清AFP,采用商用试剂盒检测血清AFU水平。绘制血清GP73、AFP-L3、AFP和AFU诊断PLC的ROC曲线,确定截断点（cut-off-value）,计算ROC曲线下面积（AUC）,判断它们的诊断效能。结果 肝癌组血清GP73水平显著低于慢性肝炎组和肝硬化组,差异有统计学意义（P<0.05）,血清AFP-L3显著高于其他3组,差异有统计学意义（P<0.05）,血清AFU水平显著高于健康人和肝硬化组,但低于慢性肝炎组,差异有统计学意义（P<0.05）;以非肝癌人群为对照,血清GP73、AFP-L3、AFP和AFU诊断肝癌的ROC曲线下面积分别为0.564（95%CI：0.485~0.636）、0.724（95%CI：0.555~0.786）、0.745（95%CI：0.654~0.806）和0.571（95%CI：0.385~0.536）,血清AFP-L3联合AFP诊断肝癌的截断点分别为8.25%和49.25 ng/ml,其灵敏度（Se）为55.5%,特异度（Sp）为85.0%,正确性（Ac）为80.1%,显著高于血清AFP-L3诊断的55.5%、85.0%和76.4%或AFP诊断的57.1%、82.7%和75.2%（P<0.05）;在261例肝癌患者中,血清AFP<9.6 ng/ml者71例（27.2%),其中PG73>106.5 ng/ml者30例（42.3%）,提示GP73对AFP阴性肝癌有一定的诊断价值;在201例肝硬化患者中,血清AFP<9.6 ng/ml者98例（48.8%）,其中PG73>106.5 ng/ml者52例（53.1%）,提示血清GP73水平容易受到肝硬化的影响。结论 应用血清AFP联合AFP-L3检测能够提高诊断肝癌的效能,但它们的灵敏度都还不够高,影响因素较多。临床医生需结合病史、影像学检查和动态血清学检测才能做出更为科学的结论。
