Antitumor mechanism of kangliu pill on gliomas in mice through PI3K-Akt signaling pathway.

Ethnopharmacological Relevance: Gliomas are common malignant intracranial tumors that have worse prognosis and pose a serious threat to human health. The Kangliu pill (KLP) is an innovative herbal compound from Xuanwu Hospital of Capital Medical University that has been clinically used for the treatment of gliomas for more than 40 years, and is one of the few drugs for primary treatment of this disorder. But the fundamental molecular mechanisms and pathways of KLP are not clear.

Partial response to Chinese patent medicine Kangliu pill for adult glioblastoma: A case report and review of the literature.

Background: Glioblastoma is the most common type of brain tumor and is invariably fatal, with a mean survival time of 8-15 mo for recently diagnosed tumors, and a 5-year survival rate of only 7.2%. The standard treatment for newly diagnosed glioblastoma includes surgery followed by concurrent chemoradiotherapy and further adjuvant temozolomide.

Beilunmycin, a new virginiamycins antibiotic from mangrove-derived sp. 2BBP-J2 and the antibacterial activity by inhibiting protein translation.

One new virginiamycin derivative, 'beilunmycin' (), and three known virginiamycin antibiotics, 16-hydroxy-virginiamycin M1 (), virginiamycin M2 (), and virginiamycin M1 (), were isolated from the culture of a mangrove-derived endophytic sp. 2BBP-J2. The structures were characterized on the basis of their spectroscopic data, and the absolute configuration of was established by ECD calculations.

[Role of CyclinD1/IgH Detection by FISH in Differential Diagnostic Significance between Mantle Cell Lymphoma and Chronic Lymphocytic Leukemia].

Objective: To investigate the feasibility of CyclinD1/IgH detection by FISH in diferential diagnosis between mantle cell lymphoma (MCL) and chronic lymphocytic leukeamia (CLL).

Methods: The FISH detection was performed for CyclinD1/IgH fusion gene. A comprehensive analysis was carried out for clinical features, such as age, sex , WBC count and lymphocyte count, the bone marrow morphology and immunohistochemical staining were carried for CyclinD1/IgH.

[Leukemia SH-1 cells purged by ZnPcH(1)-based photodynamic therapy].

The objective of this study was to investigate the effect of a novel Zinc phthalocyanine (ZnPcH(1)) based photodynamic therapy (PDT) on acute monocytic leukemia cell lines SHI-1 and its mechanism, so as to provide theory basis for bone marrow purging in vitro for patients with leukemia. The killing effect of ZnPcH(1)-PDT on SHI-1 cells were assessed by MTT method; the SHI-1 cell death patterns were analyzed by AO/EB fluorescence staining, TdT-mediated dUTP nick end labeling (TUNEL), DNA ploidy analysis, and Annexin V-FITC/PI double staining.Cell mixture was established by integrating SHI-1 cells with normal bone marrow MNC (by 1:100-1:10 000).

[Apoptosis in nasopharyngeal carcinoma cell line NCE induced by curcumin and its molecular mechanism].

Objective: To investigate the mechanism underlying the curcumin-induced apoptosis of nasopharyngeal carcinoma (NPC) cell line NCE cells.

Methods: The characteristics of apoptosis were identified by observation acridine orange and ethidium bromide stains, ultrastructure assay, DNA fragmentation assay and TdT-mediated dUTP nick end labeling method (TUNEL). Mitochondrial membrane potential (delta psi m), activity of caspase-3, cytosol cytochrome C and expression of gene Fas were determined by flow cytometry (FCM), Western Blot and reverse transcription-polymerase chain reaction (RT-PCR).
