To evaluate the clinical efficacy of Yiqi Jianpi Recipe (YJR) in treating cancer-related fatigue (CRF) after chemotherapy in lung cancer patients. Methods Totally 124 lung cancer patients were assigned to the treatment group (63 cases) and the control group (61 cases) according to random digit table. All patients received pre-set chemotherapy regimens according their conditions. Patients in the treatment group took YJR Decoction from the 1st day of chemotherapy, one dose per day for 2 successive weeks, while those in the control group took no Chinese medical decoction. Changes of each dimensional scoring and the total scoring were observed by cancer fatigue scale (CFS) in the two groups one day before chemotherapy, on the 3rd day and the 14th day after chemotherapy. The degree of bone marrow depression and recombinant human granulocyte colony-stimulating factor (rhG-CFS) doses were also observed after chemotherapy.

To explore the anti-tumor proliferation activity of human interleukin-29 (hIL-29) variant and based on bioinformatics analyzed data of hIL-29, a mutant gene hIL-29(mut33,35) was amplified by site-directed mutagenesis and megaprimer PCR. The hIL-29(mut33,35) was inserted into an eukaryotic expression plasmid pPIC9K and successfully expressed in Pichia pastoris GS115. A recombinant variant protein (rhIL-29(mut33,35)) was purified from the ferment supernatant of the engineering GS115. To observe the antineoplastic activity of the variant rhIL-29(mut33,35), a CCK-8 reagent was used to detect the anti-proliferation effect. Results show that it has strong anti-proliferation effect when acted on liver cancer cell BEL7402, colon cancer cell HCT8 and gastric cancer cell SGC7901. The inhibition ratios of the three tumor cells were (30.99 ± 1.58)%, (22.47 ± 1.37)% and (32.05 ± 2.02)%, respectively. In high dose group, the anti-proliferation effect of the rhIL-29(mut33,35) was stronger than that of wild type rhIL-29 (P < 0.01). This indicates the variant rhIL-29(mut33,35) has potential development value for medicine.

Using brartemicin as the leading compound, fifteen novel trehalose derivatives were designed and synthesized, and the structures were determined by 11H NMR, MS and element analysis. Inhibitory effects of the target compounds on the proliferation of A549, HepG2 and HUVEC cells were detectec by MTT assay. The abilities of adhesion, invasion and migration of A549 and HepG2 cells inhibited by the synthesized compounds were evaluated through Matrigel experiment and Transwell assay. The results showed that, the target compounds had no significant cytotoxicity (compared with the control, P>0.05) to A549, HepG2 and HUVEC cells at the dose range of 1-32 µmol.L-1. At the above dose range, the inhibitory effects of A549 cells adhesion, invasion and migration and HepG2 cells adhesion and invasion by compounds 79 and 82 are better than brartemicin.

Platinum-based anticancer drugs have been becoming one of the most effective drugs for clinical treatment of malignant tumors for its unique mechanism of action and broad range of anticancer spectrum. But, there are still several problems such as side effects, drug resistance/cross resistance and no-specific targeting, becoming obstacles to restrict its expanding of clinical application. In recent years, supramolecular chemistry drug delivery systems have been gradually concerned for their favorable safety and low toxicity. Supramolecular macrocycles-platinum complexes increased the water solubility, stability and safety of traditional platinum drugs, and have become hot focus of developing novel platinum-based anticancer drugs because of its potential targeting of tumor tissues/organs. This article concentrates in the research progress of the new drug delivery system between platinum-based anticancer drugs with three generations of macrocycles: crown ether, cyclodextrin, cucurbituril and calixarene.

In recent years, the chemotherapy of non-small cell lung cancer (NSCLC) has almost been reached a platform stage, and there is no obvious progress in terms of response rate (RR) and overall survival (OS); With the great development of molecular biology, epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) has good therapeutic effect on the NSCLC. But, almost all patients of EGFR-mutant lung cancers develop drug resistance to these agents. This paper reported a case of a 49-year-old woman with lung adenocarcinoma who had EGFR mutant (19-DEL) treated with EGFR-TKIs. After disease progression, histological examination of a secondary biopsy specimen revealed small cell lung cancer (SCLC) had transformed to SCLC treatment. Through the analysis of the process and effect of her therapy, the following is a summary of the relevant mechanism.

Cancer stem cells (CSCs) are emerging as a hot topic for cancer research. Lung CSCs share many characteristics with normal lung stem cells (SCs), including self-renewal and multi-potency for differentiation. Many molecular markers expressed in various types of CSCs were also found in lung CSCs, such as CD133, CD44, aldehyde dehydrogenase (ALDH) and ATP-binding cassette sub-family G member 2 (ABCG2). Similarly, proliferation and expansion of lung CSCs are regulated not only by signal transduction pathways functioning in normal lung SCs, such as Notch, Hedgehog and Wnt pathways, but also by those acting in tumor cells, such as epidermal growth factor receptor (EGFR), signal transducer and activator of transcription 3 (STAT3) and phosphatidylinositol 3 kinase (PI3K) pathways. As CSC plays an critical role in tumor recurrence, metastasis and drug-resistance, understanding the difference between lung CSCs and normal lung SCs, identifying and targeting CSC markers or related signaling pathways may increase the efficacy of therapy on lung cancer and improved survival of lung cancer patients.

The aim of this study is to explore clinical efficacy of crizotinib in advanced anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer.

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) show promising therapeutic effects in patients with advanced non-small cell lung cancer (NSCLC). However, despite an initial response to TKIs treatment among responsive patients, most inevitably acquire resistance after a progression-free period of about 10 months. The percentage of T790M in TKI acquired-resistant patients in most studies is around 50%.
