Objective To observe the influence of clopidogrel combined with proton pump inhibitor (PPI) on the postoperative complication of percutaneous coronary intervention.Methods The clinical data of 600 patients who were taking clopidogrel antiplatelet therapy were retrospectively analyzed.All patients were divided into observation group (with PPI,n =300) and control group (without PPI,n=300).In-stent restenosis (ISR) and the adverse event rates were compared between the two groups during the period of follow up.Results The incidence of gastrointestinal bleeding was less in observation group than in control group (6.7％ vs.13.7％,x2 =8.048,P＜0.01),but the incidences of ISR,target vessel revascularization (TVR) and non-fatal myocardial infarction were higher in observation group than in control group(x2 =6.426、5.511、4.718,all P＜0.05).Conclusions Clopidogrel combined with PPI treatment can significantly reduce the risk of gastrointestinal bleeding,but increase the incidences of major adverse cardiovascular events.We suggest that PPI should be used with caution for the patients who need longer-term PPI use.

Objective To analyze the changes of myeloid-derived suppressor cells (MDSCs) in peripheral blood and serum nitric oxide in tumor-bearing mice, and to explore their correlation and functions in tumor progression. Methods Orthotopic transplantation tumor model of hepatocarcinoma in mice was established. At the 7th, 14th, 21st day after tumor implantation, the proportion of peripheral blood MDSCs was tested by flow cytometry, and serum nitric oxide was detected using the method of nitric acid reductase. Results The proportion of peripheral blood MDSCs at the 7th, 14th, 21st day after tumor implantation in tumor-bearing mice was significantly higher than that in normal mice [(8.65±1.01)%, (14.20±2.52)%, (27.51± 2.98) % vs. (2.51 ±0.44) %, P<0.05]. The level of nitric oxide at the 7th, 14th, 21st day after tumor implantation in tumor-bearing mice was significantly lower than that in normal mice [(72.02 ±5.05) μmol/L, (94.70 ±3.34) μmol/L, (78.90 ± 8.19) μmol/L vs. (57.03 ±16.94) μmol/L, P<0.05]. The level of serum nitric oxide was positively associated with the proportion of MDSCs (r=0.689, P<0.01). Conclusion The proportion of peripheral blood MDSCs and the level of serum nitric oxide in mice are increased with the tumor progression, and there is a positive correlation between them.

As a newly identified T helper cell subset, Th9 plays an important role in anti-tumor immunity. Th9 can be differentiated from CD4+T cells that have been induced by TGF-beta and IL-4. In addition, other CD4+T helper cell subsets can be developed to Th9 cell in particular situations, thereby showing its plasticity. Results of animal experiments have indicated that Th9 inhibits tumor growth and plays a significant role in anti-tumor immunity by secreting related cytokines such as IL-9. A few cytokines and molecules can regu-late the differentiation and development of Th9 cells in different signaling pathways. This review will focus on the production, anti-tu-mor immunity, related mechanism, and signaling pathways of Th9 cells, thereby providing a new field of vision and idea for anti-tumor therapy in the future.
