ReviewOpportunities and obstacles of targeted therapy and immunotherapy in small cell lung cancer.
Small cell lung cancer (SCLC) is an aggressive malignant tumour which accounts for approximately 13-15% of all newly diagnosed lung cancer cases. To date, platinum-based chemotherapy are still the first-line treatments for SCLC. However, chemotherapy resistance and systemic toxicity limit the long-term clinical outcome of first-line treatment in SCLC. ⋯ At the same time, we should reveal more information about the pathogenesis of SCLC and the mechanism of drug resistance. Finally, new treatment strategies should also be taken into considerations, such as repurposing drug, optimising of targets, combination therapy strategies or prognostic biomarkers to enhance therapeutic effects and decrease the adverse events rates in SCLC patients. This article will review the molecular biology characteristics of SCLC and discuss the opportunities and obstacles of the current therapy for SCLC patients.

ReviewPharmacological and non-pharmacological efforts at prevention, mitigation, and treatment for COVID-19.
A global outbreak of the SARS-CoV-2 virus has infected millions of people over a short period of time. The communicability and increased mortality from the SARS-CoV-2 infection mandated the WHO to declare COVID-19 a worldwide pandemic. The virus outbreak has spread when there are no approved vaccines, treatments, or prophylactic therapies available. ⋯ Immunomodulatory molecules such as sarilumab, tocilizumab, janus kinase inhibitors, and hyperimmune convalescent plasma have mixed outcomes from initial clinical findings; however, pending randomised controlled trials will assist national health institutions to make treatment recommendations for COVID-19. Where compassionate use of remdesivir has shown some benefits, therapies such as hydroxychloroquine have proven harmful due to their toxicities. This review discusses pharmacological interventions at play and evidence-based successes and limitations of non-pharmacological therapies such as social distancing, personal protective equipment, and ventilator support associated with the prevention and treatment of COVID-19.

ReviewRecent advances in kartogenin for cartilage regeneration.
Either osteoarthritis or sports-related injuries can lead to cartilage defects, whereas both chondrocyte self-renewal and conventional treatments face limitations. In cartilage regenerative medicine, growth factors are commonly used to induce chondrogenic differentiation of stem cells. However, application of growth factors is confined by some drawbacks. ⋯ KGN has been processed and applied in many forms, such as in intra-articular injection, in collaboration with growth factors, in incorporation in drug delivery systems, and in combination with scaffolds. Fortunately, progress has been achieved in KGN applications. The current review discusses the recent advances in KGN for cartilage regeneration and thus presents new concepts in cartilage repair in clinical settings.

A novel antibody-drug conjugate anti-CD19(Fab)-LDM in the treatment of B-cell non-Hodgkin lymphoma xenografts with enhanced anticancer activity.
Rituximab is widely used in clinical setting for the treatment of B malignant lymphoma and has achieved remarkable success. However, in most patients, the disease ultimately relapses and become resistant to rituximab. To overcome the limitation, there is still a need to find novel strategy for improving therapeutic efficacy. ⋯ The present study demonstrated that the genetically engineered antibody anti-CD19(Fab)-LDM exhibited enhanced cytotoxicity compared to LDM alone. One of the most powerful advantages of anti-CD19(Fab)-LDM, however, is that it can be internalized within the cells and carry out cytotoxic effects. Therefore, anti-CD19(Fab)-LDM may be as a useful targeted therapy for B-cell lymphoma.

ReviewIbrutinib-A double-edge sword in cancer and autoimmune disorders.
Targeted therapies have appeared as new treatment options for several disease types, including cancer and autoimmune disorders. Of several targets, tyrosine kinases (TKs) are among the most promising. Overexpression of TKs provides a target for novel therapeutic agents, including small molecule inhibitors of tyrosine kinases (TKI). ⋯ This changes the balance of Th1/Th2 cells toward Th1 subset, which are the main immune cells targeting tumor cells. The dual activity of ibrutinib has paid a great attention and several studies are evaluating the anti-tumor and immunomodulatory effects in cancer, autoimmune disorders and infectious diseases. In this article we review the inhibitory and immunomodulatory effects of ibrutinib in B-cell malignancies, autoimmune diseases and infections, as well as the communication between the Ror1 receptor tyrosine kinase and BCR and effects of ibrutinib on this crosstalk.
