Abstract
Gastric cancer remains one of the most lethal cancers with high incidence and mortality worldwide. The majority of gastric cancer patients are those who have first been diagnosed in advanced stage, in which the standard chemo-radiotherapy produces limited benefit along with severe general toxicity, thus the demand for improved therapeutic efficacy and decreased side effects drives the development of novel therapeutic strategies. Here, a neoadjuvant chemotherapy based on Abraxane/human neutrophils (NEs) cytopharmaceuticals with radiotherapy is presented for effective cancer treatment. Human NEs, the most abundant white blood cells in peripheral blood, are developed to carry Abraxane, the commercial albumin-bound paclitaxel nanoparticle, to form cytopharmaceuticals (Abraxane/NEs) which have been confirmed to maintain the intrinsic functions of human NEs. The modest radiation is applied not only to exert tumor disruption, but also to increase the release of inflammatory factors which guide the NEs homing to the tumoral sites. These amplified inflammatory factors at tumor sites excessively activate Abraxane/NEs to form neutrophil extracellular traps, along with a burst release of Abraxane to induce superior tumor suppression. This adjuvant chemo-radiotherapy based on cytopharmaceuticals may provide new opportunities for advanced cancer treatment, which reveals the huge clinical potential of human neutrophils as drug delivery vectors.

[PMID: 30071135 DOI: 10.1111/1440-1681.13021] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2018] [Revised: 06/29/2018] [Accepted: 07/03/2018] [Indexed: 12/15/2022]
Abstract
Recently, the roles of interleukin-2 (IL-2), IL-4, IL-6 and IL-8 gene polymorphisms in gastric cancer (GC) have been studied extensively, with conflicting results. Therefore, we conducted the present meta-analyses to better elucidate the roles of interleukin gene polymorphisms in GC. Eligible articles were searched in PubMed, MEDLINE, Embase, Web of Science and CNKI. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to detect any potential association between interleukin gene polymorphisms and the risk of GC. A total of 63 case-control studies was finally included in our analyses. Significant associations with the risk of GC were detected for the IL-6 rs1800796 and IL-8 rs4073 polymorphisms in overall analyses. Further subgroup analyses based on ethnicities of participants revealed that the IL-4 rs2243250, IL-6 rs1800796 and IL-8 rs4073 polymorphisms were significantly associated with the risk of GC in Asians. Moreover, IL-8 rs4073 polymorphism was also significantly associated with the risk of GC in Africans. In conclusion, our findings suggested that IL-4 rs2243250, IL-6 rs1800796 and IL-8 rs4073 polymorphisms may serve as genetic biomarkers of GC.

Abstract
Changes in immune and inflammatory responses may play a crucial role in the development and progression of atherosclerosis, as an autoimmune, chronic and progressive inflammatory disease. Immunological activity and vascular inflammation during atherosclerosis can be modulated by autoimmune responses against self-antigens, according to changeable risk factors (cholesterol, oxidized low-density lipoprotein (ox-LDL) in the vascular wall, fatty acids, etc.), and accompanied by accumulation of leucocytes and proinflammatory cytokines, which stimulate the transcription of matrix metalloproteinases (MMPs), whose concentration are increased in foam cell-rich regions. Regulatory T cells (Tregs) represent a unique subpopulation of T cells specialized in the regulation of immune response and in the suppression of proatherogenic T cells. The aim of our study was to examine the interactions between the concentration of enzyme matrix metalloproteinases 2 and 9 (MMP-2 and 9) in urine and the percentage of Tregs in peripheral blood of two groups of patients: with carotid artery stenosis (CAS), undergoing surgery and with mild atherosclerosis (A) from general practice. The method of enzyme immunoassay (ELISA) was used to determine enzyme MMP expression, and Tregs was examined by flow cytometric analysis. Our data have showed a large increase in the enzyme MMP-2 and 9 in the urine of CAS and A patients in comparison with healthy controls and indicated this method as an easy marker for the monitoring of the development of atherosclerosis. Simultaneously, the diminished number of Tregs in the same patients pointed the importance of these regulatory mechanisms in the etiopathogenesis of atherosclerosis and possible Tregs-mediated therapy.

Strategies and Advancements in Harnessing the Immune System for Gastric Cancer Immunotherapy. J Immunol Res 2015; 2015:308574.

Abstract
In cancer biology, cells and molecules that form the fundamental components of the tumor microenvironment play a major role in tumor initiation, and progression as well as responses to therapy. Therapeutic approaches that would enable and harness the immune system to target tumor cells mark the future of anticancer therapy as it could induce an immunological memory specific to the tumor type and further enhance tumor regression and relapse-free survival in cancer patients. Gastric cancer is one of the leading causes of cancer-related mortalities that has a modest survival benefit from existing treatment options. The advent of immunotherapy presents us with new approaches in gastric cancer treatment where adaptive cell therapies, cancer vaccines, and antibody therapies have all been used with promising outcomes. In this paper, we review the current advances and prospects in the gastric cancer immunotherapy. Special focus is laid on new strategies and clinical trials that attempt to enhance the efficacy of various immunotherapeutic modalities in gastric cancer.

Abstract
The aim of this study was to investigate the effect of Helicobacter pylori (Hp) on cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) levels in patients with gastric precancerous lesions and its clinical significance. A total of 114 patients with gastric precancerous lesions, 57 whom were positive for Hp (observation group) and 57 of whom were negative for Hp (control group), were selected for the study. The mRNA levels of COX-2 and iNOS in the gastric precancerous lesion tissue from the two groups of patients were analyzed through the reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The protein expression levels of COX-2 and iNOS were analyzed using western blotting and an iNOS kit, respectively. In addition, normal human gastric mucosal GES-1 cells were cultured in vitro and stimulated by Hp for 3, 6, 9 and 12 h. The variations in the mRNA and protein levels of COX-2 and iNOS were then analyzed via RT-qPCR and western blotting. Compared with the control group, the mRNA levels of COX-2 and iNOS in the gastric tissue from the observation group were significantly increased (P<0.05). Furthermore, the expression level of COX-2 and iNOS protein in the gastric tissue from the observation group was significantly higher than that in the tissue from the control group (P<0.05). In vitro analysis showed that the COX-2 and iNOS mRNA and protein levels were significantly increased in the Hp-stimulated normal human gastric mucosal GES-1 cells compared with those in the unstimulated cells. Furthermore, the effect was time-dependent (P<0.05). In conclusion, COX-2 and iNOS are the main inflammatory markers. Hp can induce high expression levels of COX-2 and iNOS in gastric precancerous lesion tissue, which may be associated with the occurrence and development of gastric precancerous lesions.

Abstract
The vast majority of gastrin-related gastrointestinal neuroendocrine neoplasms (GI-NENs) develop in the context of chronic atrophic gastritis (type 1), a condition closely related to autoimmune thyroid diseases. These neoplasms are defined as gastric NENs type 1 (GNEN1) and have recently been shown to constitute the commonest GI-NENs in a prospective study. GNEN1s are usually multiple and follow a relative indolent course, raising questions regarding the extent that such patients should be investigated and the appropriate therapeutic interventions needed. Recently, a number of consensus statements and guidelines have been published from various societies dealing with the diagnosis and management of GI-NENs. Endocrinologists are among the many different medical specialties involved in GNEN1s diagnosis and management. However, despite recent advances, few randomized trials are available, and thus existing evidence remains relatively weak compared to other malignancies. The purpose of this review is to provide recent evidence along with currently employed modalities addressing the diagnosis, management, long-term follow-up and potential comorbidities of GNEN1s.
