Background: Phase II-III trials in patients with untreated and previously treated locally advanced or non-small cell lung cancer (NSCLC) suggested that Endostar was able to enhance the effect of platinum-based chemotherapy (NP regimen) with tolerable adverse effects. Methods: Four hundred and eighty six patients were randomized into two arms: study arm A: NP plus Endostar (n = 322; vinorelbine, cisplatin, Endostar), and study arm B: NP plus placebo (n = 164; vinorelbine, cisplatin, 0.9% sodium chloride). Patients were treated every third week for two to six cycles. Results: Overall response rates were 35.4% in arm A and 19.5% in arm B (P = 0.0003). The median time to progression was 6.3 months for arm A and 3.6 months for B, respectively (P < 0.001). The clinical benefit rates were 73.3% in arm A and 64.0% in arm B (P = 0.035). Grade 3/4 neutropenia, anemia, and nausea/vomiting were 28.5%, 3.4%, and 8.0%, respectively, in Arm A compared with 28.2%, 3.0%, and 6.6%, respectively, in Arm B (P > 0.05). There were two treatment related deaths in arm A and one in arm B (P > 0.05). The median overall survival was longer in arm A than in arm B (P < 0.0001). Conclusion: Long-term follow-up revealed that the addition of Endostar to an NP regimen can result in a significant clinical and survival benefit in advanced NSCLC patients, compared with NP alone.

Patients with sepsis commonly suffer from coagulation dysfunction and lead to the formation of thrombus. During the development of sepsis, neutrophils migrate from the circulating blood to infected tissues and mediate the formation of neutrophil extracellular traps (NETs) that kill pathogens. However, the overactivation of neutrophils can promote the formation of immunothrombosis and even cause disseminated intravascular coagulation (DIC), which damages microcirculation. The outcome of sepsis depends on early recognition and intervention, so clinical evaluation of NETs function may be a valuable biomarker for early diagnosis of sepsis. The interaction of NETs with platelets, complement, and endothelium mediates the formation of immunothrombosis in sepsis. Inhibiting the formation of NETs is also considered to be one of the potential treatments for sepsis. In this review, we will discuss the key role of neutrophils and NETs in sepsis and septic thrombosis, in order to reveal new mechanisms for thrombosis treatment of sepsis.

p57 is a multifunctional protein involved in the regulation of tumor formation and development; however, the biological role of p57 in the pathogenesis of hepatocellular carcinoma (HCC) is poorly understood. To explore the role of p57 in the development of HCC, we examined p57 messenger RNA (mRNA) and protein levels in HCC tissues and adjacent non-cancerous tissues by immunohistochemistry, real-time polymerase chain reaction and western blot analysis. Moreover, we generated stable p57 knockdown HCC cell lines to investigate the impact of p57 downregulation on the growth and invasion of HCC in vitro and in vivo. Our results showed that p57 mRNA and protein levels were significantly decreased in human HCC tissues. In addition, this reduction in p57 expression was associated with increased tumor size, more advanced TNM stages, the presence of capsule invasion and extrahepatic metastasis and decreased overall survival time. In human HCC cell lines, p57 downregulation increased the expression of cyclin D1 and CDK2 and enhanced the activities of CDK4/cyclin D1 and CDK2/cyclin E complexes, resulting in increased cellular proliferation and growth of xenografts. Furthermore, p57 downregulation accelerated the invasion of HCC cells in vitro and in vivo by controlling the activity of LIMK1. In conclusion, the downregulation of p57 accelerates the growth and invasion of HCC, indicating that p57 is an important tumor suppressor in HCC. Based on these findings, p57 may be a potential target for HCC prevention and therapy.
