目的探究早期帕金森病(PD)患者血清中胱抑素(Cys)C、同型半胱氨酸(Hcy)的表达情况及其与睡眠障碍的相关性。方法选取86例早期PD患者作为观察组,同期选择58例医院体检的健康人作为对照组,采用免疫比浊法测定血清CysC水平,酶转化法测定血清Hcy水平,采用PD睡眠量表(PDSS)评估受试者整体睡眠障碍的情况,分析血清中CysC、Hcy水平与睡眠障碍的相关性。结果观察组血清CysC、Hcy水平显著高于对照组(P<0.05);早期PD患者血清CysC与Hcy水平正相关(r=0.672,P<0.05);观察组PDSS总评分(PDSS-T)显著低于对照组(P<0.05);早期PD患者血清CysC、Hcy水平与PDSS-T评分均呈负相关(r=-0.663、r=-0.457,P<0.05)。结论早期PD患者血清CysC、Hcy水平上调,与患者睡眠障碍有关,可能作为早期PD患者睡眠障碍的预测因子。

The present study aimed at solving this ***: A total of 225 patients included in this study,were admitted from January 1998 to December 2001 for an unresectable HCC proven by histological and imaging examinations. Most of the patients received interventional treatment, radiation and biotherapy. Response was evaluated by computerized tomography (CT) scan conducted 4-6 weeks following completion of the treatment, and then every 3months, Survival was calculated from the beginning of treatment using the Kaplan-Meier method. Pretreatment,treatment and follow-up variables with possible prognostic significance were analyzed. A stepwise multivariate analysis was performed using the Cox regression model, and a prognostic index was ***: No differences were observed in survival parameters between the patients with and without hyperglycemia, median survival times of the patients were being 26±3.46 months and 29.5±2.04 months, respectively, and the 3-year survival rate was 8.36%and 9.62%, respectively. The univariate analysis indicated that there were several survival-associated variables including serum AFP level, clinical stage, Child-Pugh grade,method of treatment, size and number of tumor nodule (s).However, only the clinical stage, Child-Pugh grade and the treatment procedure were proved to be independent prognostic factors in the multivariate ***: This study indicates that hyperglycemia does not influence the long-term prognosis of HCC, and concurrent hyperglycemia should not be considered as an unfavorable prognostic factor during the treatment of patients with HCC.

Transition metal-based nanomaterials have emerged as promising electrocatalysts for oxygen evolution reaction（OER）. Considerable research efforts have shown that self-reconstruction occurs on these nanomaterials under operating conditions of OER process. However, most of them undergo incomplete reconstruction with limited thickness of reconstruction layer, leading to low component utilization and arduous exploration of real catalytic mechanism. Herein, we identify the dynamic behaviors in complete reconstruction of Co-based complexes during OER. The hollow phytic acid（PA） cross-linked CoFe-based complex nanoboxes with porous nanowalls are designed because of their good electrolyte penetration and mass transport ability, in favor of the fast and complete reconstruction. A series of experiment characterizations demonstrate that the reconstruction process includes the fast substitution of PA by OH-to form Co（Fe）(OH)xand subsequent potential-driven oxidation to Co（Fe）OOH. The obtained CoFeOOH delivers a low overpotential of 290 mV at a current density of 10 mA cm-2and a long-term *** experiment results together with theory calculations reveal that the Fe incorporation can result in the electron rearrangement of reconstructed CoFeOOH and optimization of their electronic structure,accounting for the enhanced OER activity. The work provides new insights into complete reconstruction of metal-based complexes during OER and offers guidelines for rational design of high-performance electrocatalysts.
