Clinical study of lung-supplementing and stasis-dissolving decoction (Bufei Huayu Tang) combined with gefitnib for treatment of advanced non-small cell lung cancer.

To investigate the clinical efficacy and drug safety of Lung-Supplementing and Stasis-Dissolving Decoction (Bufei Huayu Tang) combined with gefitnib for treatment of advanced non-small cell lung cancer (NSCLC). Then, 80 patients with advanced NSCLC hospitalized in Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine were included, and were double-blindly randomized into 4 groups: control group (gefitinib alone 250mg, once daily), low-dose group (100mL/day), middle-dose group (150mL/day) and high-dose group (200mL/day) treated with different doses of Bufei Huayu Tang besides gefitinib. Clinical efficacy, life quality change before and after treatment, ECOG score, survival time and incidence of adverse drug reaction were compared.

Sulforaphane inhibits cancer stem-like cell properties and cisplatin resistance through miR-214-mediated downregulation of c-MYC in non-small cell lung cancer.

We herein report that sulforaphane (SFN), a potent anti-cancer and well-tolerated dietary compound, inhibits cancer stem-like cell (CSC) properties and enhances therapeutic efficacy of cisplatin in human non-small cell lung cancer (NSCLC). SFN exerted these functions through upregulation of miR-214, which in turn targets the coding region of c-MYC. This finding was further corroborated by our observations that plasmid or lentiviral vector-mediated expression of 3'UTR-less c-MYC cDNA and cisplatin- or doxorubicin-induced endogenous c-MYC accumulation was similarly suppressed by either SFN or miR-214.

Therapeutic effect and apoptosis mechanism of lung-tonifying and expectorant decoction on lung cancer rats with Qi deficiency and blood stasis.

Objective: To explore the effect and specific mechanism of lung-tonifying and expectorant decoction on lung cancer rats with Qi deficiency and blood stasis, and aim to provide a new idea on treating the disease with traditional Chinese medicine based on syndrome differentiation.

Methods: A total of 60 C57BL/6J male rats were included in the study. The model of Qi deficiency and blood stasis was established in 60 rats by using multiple-factor stimulation.

CDA-2 induces cell differentiation through suppressing Twist/SLUG signaling via miR-124 in glioma.

Cell differentiation agent-2 (CDA-2) is an extraction from healthy human urine consisting of primary organic acids and peptides, and it has been demonstrated to inhibit growth and induce differentiation in glioma and other cell lines. But the mechanism of CDA-2 remains unclear. In this study, we demonstrated that CDA-2 inhibited cell growth and induced differentiation of glioma cells, accompanied with decreased expression of SLUG, Twist and Vimentin in both SWO-38 and U251 cell lines.

Esophageal cancer tumorspheres involve cancer stem-like populations with elevated aldehyde dehydrogenase enzymatic activity.

Cancer stem cells (CSCs) form spheres in vitro in serum-free suspension culture. Sphere formation is particularly useful to enrich the potential CSC subpopulations as a functional approach. Few reports are currently available on tumorspheres in esophageal cancer (EC).

[Expression of peroxisome proliferator-activated receptor gamma in glioma].

Objective: To investigate the expression and significance of peroxisome proliferators-activated receptor gamma (PPAR gamma) in human glioma.

Methods: Immunohistochemical staining for PPAR gamma was performed using biopsy specimens of human glioma of various histological types. Expression of PPAR gamma and GFAP in glioma cell lines SWO-38, U251 and SHG-44 were analyzed using Western blotting and reverse transcription-polymerase chain reaction (RT-PCR).

[Effects of exogenous human chorionic gonadotropin on nude mice bearing endometrial carcinoma].

Objective: To observe the effects of exogenous human chorionic gonadotropin (hCG) on nude mice bearing transplanted endometrial carcinoma.

Methods: Human endometrial carcinoma xenograft was transplanted in nude mice, and the effects of hCG injection on the tumor growth was evaluated according to tumorigenesis and xenograft weights. The expression of Ki-67 in the tumor was determined by immunohistochemistry, and HE staining was performed for morphological observation and measurement of the necrosis area in the tumor.
