1.Comprehensive therapeutic strategies regarding immune checkpoint
Chinese Journal of Clinical Oncology 2017;44(15):782-786
The rapid development of immunotherapy has exceeded that of standard treatment modes, which include surgery, radio-therapy, chemotherapy, and targeted therapy. Immunotherapy is more durable and less toxic than traditional cancer therapies. More-over, immune checkpoint therapy is an important component of immunotherapy and has been evaluated in preclinical and clinical tri-als and proven to exhibit broad prospects. However, its clinical benefits are limited to a small subset of patients with a subset of tumor types. Therefore, reasonable comprehensive therapeutic strategies are needed to overcome this limitation. Gene targeted therapy, ra-diotherapy, chemotherapy, and tumor vaccine affect the immune system through different mechanisms, and these could provide theo-retical bases for comprehensive treatments. In this review, immune checkpoint therapy and its potential comprehensive therapies with other cancer treatments are introduced.

Objective To explore clinical implications of pleural effusion in thoracic endovascular aorta repair (TEVAR) of type B aortic dissection.Methods Clinical data of 28 patients (23 males,5 females) hospitalized from Jan 2015 to Dec 2016 were analyzed retrospectively.There were ruptured aortic dissection (RAD) (n =7) and the contained aortic dissection (CAD) (n =21).26 patients underwent TEVAR,and two patients received conservative treatment.Results 26 patients received TEVAR and operations were successful.2 patients treated conservatively died.Six patients had bilateral pleural effusion,while 20 had left pleural effusion and two had right pleural effusion.The distribution of pleural effusion was significantly different between CAD and RAD group (x2 =10.4,P < 0.05),and the rupture risk was the highest in right sided pleural effusion.The median volume of pleural effusion on right side in RAD group are higher than that in CAD group (Z =-3.293,P =0.001).One patient died of sudden death on post-op 9th day.Pleural effusion disappeared in all 24 patients who were followed-up for more than 3 months.There were no ensuing pleural thickening,pulmonary atelectasis,and lung consolidation.Conclusious Pleural effusion on left side are common in type B aortic dissection,while bulk right pleural effusion may indicate impending rupture.Endovascular therapy is a feasible,safe and effective therapy for aortic dissection with pleural effusion.

Functional electronic stimulation (FES) may provide a means to restore motor function in patients with spinal cord injuries. The goal of this study is to determine the regions in the spinal cord controlling different hindlimb movements in the rats. Normalization was used for the regions dominating the corresponding movements. It has been verified that FES can be used in motor function recovery of the hindlimb. The spinal cord was stimulated by FES with a three-dimensional scan mode in experiments. The results show that stimulation through the electrodes implanted in the ventral locations of the lumbosacral enlargement can produce coordinated single- and multi-joint hindlimb movements. A variety of different hindlimb movements can be induced with the appropriate stimulation sites, and movement vectors of the hindlimb cover the full range of movement directions in the sagittal plane of the hindlimb. This article drew a map about spinal cord motor function of the rat. The regions in the spinal cord which control corresponding movements are normalized. The data in the study provide guidance about the location of electrode tips in the follow-up experiments.
