With the elucidation of structures and functions, antibodies are widely applied in the diagnosis and treatment of diseases. Today, therapeutic antibodies have played ever increasing roles in the treatment of cancers. In fact, there are over 20 monoclonal antibodies which have been approved by the U.S.Food and Drug Administration (FDA) for the therapeutic use in cancers. For the gastric and colorectal cancers, there are at least 9 antibodies have been approved for cancer therapy or for clinical trials. These antibody drugs target to tumor associate antigens and can destroy the cancer cells through several mechanisms such as antibody-dependent cell cytotoxicity, complement-dependent cytotoxicity, blockage of blood nutrition and crucial signaling pathways. With the progress in gene engineering technology, the diverse structures of antibodies can be created. In addition, the antibody-conjugates with radioisotopes, toxins and cytotoxins, are also designed for targeted therapy of gastric and colorectal cancers. In this article, we review the trends in the clinical development and application of antibody drugs for future research and development of the rapidly expanding therapeutic modality in gastric and colorectal cancers.

Objective To explore the value of trauma-care check list (TCC) and quick sequential organ failure assessment (qSOFA) on the early diagnosis of severe trauma with sepsis,and analyze the treatment time lines.Methods Totally 120 patients with severe trauma treated in Taizhou People's Hospital from February 2017 to January 2018 were reviewed.Sixty cases adopted TCC and qSOFA trauma care integration process (integration group),and the rest 60 cases adopted systemic inflammatory response syndrome (SIRS) score and emergency surgery multi-section support process (traditional group).According to the 2016 International Sepsis Guide Criteria,the diagnostic sensitivity and specific degrees of the two groups were calculated.The treatment time node,blood loss,complication rate,postoperative survival rate,and the total length of hospital stay of the two groups were analyzed.Results Of the 60 cases in the integration group,32 cases were confirmed severe trauma with sepsis,and 27 cases were confirmed in 41 primary diagnosed patients,with a diagnostic sensitivity of 84.38％ and a specific degree of 50.00％.In the traditional group,30 cases were confirmed severe trauma with sepsis,and 25 cases were confirmed in 38 primary diagnosed patients with a diagnostic sensitivity of 83.33％ and a specific degree of 56.67％.The significant shorter MDT consultation time,primary diagnosis time of sepsis,the duration from injury to surgery time and total hospitalization time were statistically significant different between the two groups (P＜0.05).Patients in the integration group had significantly lower incidence of postoperative complications and 28-day fatality rate,but there was no significant difference between them (P＞0.05).Conclusions TCC and qSOFA score in the treatment of severe trauma can optimize salvage process,significantly shorten the treatment time,and reduce postoperative complications.Moreover,qSOFA score and SIRS score have the same effect on the early diagnosis of sepsis in patients with severe trauma.
