Prediction of recurrence and prognosis in patients with hepatocellular carcinoma after resection by use of CLIP score

World Journal of Gastroenterology 2002年第2期8卷 237-242页

AIM: The survival time of patients with hepatocellular carcinoma (HCC) after resection is hard to predict. Both residual liver function and tumor extension factors should be considered. A new scoring system has recently been proposed by the Cancer of the Liver Italian Program (CLIP). CLIP score was confirmed to be one of the best ways to stage patients with HCC. To our knowledge, however, the literature concerning the correlation between CLIP score and prognosis for patients with HCC after resection was not published. The aim of this study is to evaluate the recurrence and prognostic value of CLIP score for the patients with HCC after resection. METHODS: A retrospective survey was carried out in 174 patients undergoing resection of HCC from January 1986 to June 1998. Six patients who died in the hospital after operation and 11 patients with the recurrence of the disease were excluded at 1 month after hepatectomy. By the end of June 2001, 4 patients were lost and 153 patients with curative resection have been followed up for at least three years. Among 153 patients, 115 developed intrahepatic recurrence and 10 developed extrahepatic recurrence, whereas the other 28 remained free of recurrence. Recurrences were classified into early (3 year) recurrence. The CLIP score included the parameters involved in the Child-Pugh stage (0-2), plus macroscopic tumor morphology (0-2), AFP levels (0-1), and the presence or absence of portal thrombosis (0-1). By contrast, portal vein thrombosis was defined as the presence of tumor emboli within vascular channel analyzed by microscopic examination in this study. Risk factors for recurrence and prognostic factors for survival in each group were analyzed by the chi-square test, the Kaplan-Meier estimation and the COX proportional hazards model respectively. RESULTS: The 1-, 3-, 5-, 7-,and 10-year disease-free survival rates after curative resection of HCC were 57.2%, 28.3%, 23.5%, 18.8%, and 17.8%, respect

Herein, the de novo synthesis of atropisomeric benzofurans through the Cu/spirocyclic-pyrrolidine-oxazoline(SPDO) complex catalyze asymmetric formal [3 + 2] cycloaddition between quinones and ynamides is explored, producing a range of structurally diverse axially chiral benzofurans in satisfactory yields with good to excellent enantioselectivities. Furthermore, density functional theory calculations were applied to explain the possible reaction mechanism.

目的研究二乙氧基乙醇(2-Ethoxyethanol,2-EE)对大鼠睾丸生精细胞中Bax,细胞色素C(Cytochrome C,CytC)以及Caspase-3表达的影响,探讨其在生精细胞凋亡调控中的作用。方法选择Wistar大鼠,分别给予剂量400、800和1200mg/kg的2-EE,连续灌胃7d,对照组以等量生理盐水灌胃,分别于末次染毒后第1和29天处死动物。采用免疫组化法(SP法),观察不同剂量染毒后及自然恢复4周后生精细胞中Bax,CytC以及Caspase-3的表达情况。结果400、800和1200mg/kg染毒7d后,大鼠睾丸生精细胞中Bax,CytC以及Caspase-3的表达水平不同程度的上升,尤其以800mg/kg组最为明显。自然恢复4周后,生精细胞中Bax,CytC以及Caspase-3的表达基本接近对照组水平。结论在本试验条件下,2-EE急性染毒可能通过影响大鼠睾丸生精细胞中Bax,CytC和Caspase-3的释放,调控生精细胞凋亡,与2-EE所致睾丸毒性的可恢复性高度相关。

Harnessing therapeutic potential of induced pluripotent stem cell–derived endothelial cells for remyelination in the central nervous system

引用

Neural Regeneration Research 2025年第6期20卷 1715-1716页

作者： Dan ma Nona Pop Aston Medical School College of Health and Life SciencesAston UniversityBirminghamUK

Myelin is the protective sheath surrounding nerve fibers, and its damage(demyelination) occurs in many central nervous system(CNS) diseases, including multiple sclerosis(MS), traumatic injury, neurodegenerative diseases such as Alzheimer's disease, and mental disorders such as schizophrenia(Barateiro et al., 2016). Repair of damaged myelin sheaths(remyelination) often fails in MS, leading to neuronal loss and irreversible functional deficits.

Parkinson's disease(PD) has a complex and multifactorial pathophysiology. Various studies, conducted both in pre-clinical models and PD patients, have reported a link between the disruption of calcium(Ca^(2+)) homeostasis and the subsequent development of PD. Ca^(2+) regulation is crucial for neuronal survival, differentiation,exocytosis at synapses,gene transcription,and proliferation.
