Mechanisms of Compound Kushen Injection for the treatment of bladder cancer based on bioinformatics and network pharmacology with experimental validation.

Bladder cancer is the most common malignancy of the urinary system. Compound Kushen Injection (CKI) is a Chinese medicinal preparation that has been widely used in the treatment of various types of cancers in the past two decades. However, the pharmacological effect of CKI on bladder cancer is not still completely understood.

Effects of RNA interference-mediated E-selectin gene silencing on cell adhesion molecule expression and cell-cell adhesion in vascular endothelial cells in mice with immunologic contact urticaria.

Contact urticaria is recognized as the wheal and flare reaction at a site from direct contact with a chemical or protein agent. Ongoing studies have proposed that gene silencing may have a promising future in finding optimal treatment of a variety of disease; hence, the aim of the study was to investigate the effect of RNA interference-mediated E-selectin ( SELE) gene silencing on cell adhesion molecule expression and on cell-cell adhesion in vascular endothelial cells (VECs) in a mouse model of immunologic contact urticaria (ICU). Following the successful establishment of mouse models of ICU induced by antidinitrophenol immunoglobulin E (IgE) combining 2,4-dinitrofluorobenzene challenge, enzyme-linked immunosorbent assay and immunohistochemistry were used to measure the levels of IgE, interleukin 4 (IL-4), interferon-γ (IFN-γ), and histamine as well as the positive expression rate of SELE, respectively.

Comparison of capillary electrophoresis and high performance liquid chromatography for detection and quantification of hemoglobin New York.

Background: Hemoglobin (Hb) New York [β113 (G15) Val→Glu, GTG→GAG], also known as Hb Kaohsiung, is one of the most common Hb variants in South China. Currently, most used screening methods for hemoglobinopathies in South China are high performance liquid chromatography (HPLC) and capillary electrophoresis (CE). However, there is no study comparing the performance of CE and HPLC in the detection of Hb New York.

Efficacy of Zhuling polyporus polysaccharide with BCG to inhibit bladder carcinoma.

There is growing interest in reducing Bacille Calmette-Guerin (BCG) side effects while keeping intact its therapeutic efficacy. In the present study, we evaluated the efficacy of Sclerotia of Polyporus umbellatus FRIES (Zhuling) and its main ingredient Polyporus Polysaccharide (PPS) to attenuate side effects of BCG therapy in vivo. The results show that bladder cancer development in model rats exhibited significantly reduced cancer invasiveness with Zhuling PPS combined with BCG.

[Clinical and molecular characteristics of hemoglobin New York in Guangxi populations].

Objective: To analyze the clinical and molecular characteristics of hemoglobin New York in populations from Guangxi and provide reference data for screening thalassemia.

Methods: A total of 30 691 samples were screened by capillary electrophoresis, and then suspicious samples of Hb New York were identified by DNA sequencing and analysis of blood cell count. Gap-PCR and reverse dot blot hybridization method were used for the detection of common mutations of α and β thalassemia in Chinese.

[Phenotype and genotype analysis of hemoglobin E].

Objective: To analyze the genotype and phenotype correlation in the hemoglobin E (HbE) carriers, and to investigate the effect of HbE on hematological parameters.

Methods: The capillary electrophoresis was used to screen total 14 141 samples and blood cell analysis was further processed to the HbE carrying samples. Gap-PCR and reverse dot blot hybridization method were used for the detection of Chinese common mutation of α and β thalassemia.

Aberrant expression of E-cadherin in lung tissues of patients with probable lung cancer.

Introduction: This study assessed the relationship of E-cadherin mRNA and protein expression with the diagnosis of lung cancer with the aim of providing an auxiliary diagnostic method.

Methods: Semi-quantitative nested RT-PCR and western blotting were applied to detect E-cadherin mRNA transcripts and protein, respectively, in 30 cases of diagnostic lung cancer, 30 cases of clinically suspected patients with lung cancer and 30 cases of other disease. Immunohistochemical staining was also used to detect E-cadherin.
