Small cell lung cancer(SCLC) is a type of neuroendcorine cancer with high growth fraction, early metastatic spread and poor prognosis, accounting for approximately 15％ of all newly diagnosed lung cancer cases.Patients with SCLC are generally treated with platinum-based chemotherapy in combination with radiotherapy.Despite good responses to chemotherapy in the early stage of treatment, patients develop drug resistance and recurrence soon.There has been limited success with the targeted approaches in clinical trials completed in the past several years.Novel targeted and more effective treatment strategies for SCLC are in urgent need With increasing translational research and a better understanding of the molecular basis of small cell lung cancer, a number of new targeted drugs such as kinase inhibitors, angiogenesis inhibitors, apoptosis inducers, proteasome inhibitors, epigenetic regulators, immune checkpoint inhibitors have been developed and investigated in various preclinical studies.Some of them have entered clinical trials.At the same time, a number of novel treatment strategies such as immunotherapy and combination treatment receive attention.This review summarizes potentially molecular targeted therapies that have been developed and employed recently, and ongoing and future clinical trials in attempt to improve patient outcomes in SCLC, and meanwhile to invite future potential SCLC new treatment strategies.

Objective To evaluate the influence of Chinese patent medicine Banlangen Granules and Ganmao Qingre Granules on war‐farin anticogulation effect during the process for treating acute upper respiratory tract infection in the postoperative patients with mechanical valve replacement in order to provide the theoretical reference for clinical medication .Methods The patient receiving mitral valve replace‐ment ,aortic valve replacement or double‐valve replacement and long term postoperative oral warfarin anticoagulation treatment were select‐ed ,moreover the symptoms of complicating acute upper respiratory tract infection occurred .The patients were divided into 2 groups ,30 cases in each group .The group A adopted oral Banlangen Granules ,while the group B was treated by oral Ganmao Qingre Granules .The treat‐ment course was 3 d .The International Normalized Ratio (INR) in the two groups was monitored before medication ,at 72 h after medication and at 72 h after drug withdrawal .Complicating bleeding or embolism reaction was observed .The INR values at various time points were compared between the two groups and the INR values in each group were compared among 3 time points .Results The INR values in the Banlangen Granules group had statistical differences between 72 h and other two time points ,and the INR values at the same time point had statistical difference compared with the Ganmao Qingre Granules group (P<0 .05);the INR value in the Banlangen Granules group had no statistical difference between before medication and at 72 h after medication(P>0 .05) .Thirty cases had no complication occurrence .The Ganmao Qingre Granules group had no statistical difference among various time points (P>0 .05) ,thirty cases had no complication occur‐rence .Conclusion The warfarin combined with Banlangen Granules causes the INR value increase ,while warfarin combined with Ganmao Qingre Granules has no impact on the INR value ,therefore which suggests that the combination use of warfarin and Banlangen Granules should be cautious in clinic .
