C-C motif chemokine ligand 2 (CCL2) and its receptor CCR2 are closely related to tumorigenesis and tumor progression. The CCL2/CCR2 signaling axis promotes tumor progression through multiple mechanisms: CCL2 binds to CCR2 on the surface of tumor cells, and thus promotes tumor growth/survival and metastasis; more importantly, CCL2 recruits a variety of immunosuppressive cells to aggregate in the tumor microenvironment, and inhibits the function and activity of immune cells, promoting tumor progression. The article reviews the CCL2/CCR2 signaling axis and its role in tumors and tumor microenvironment, with particular focus on the advances in clinical research on drugs targeting CCL2/CCR2 signaling axis, in order to gain an in-depth and overall understanding of the mechanism of action of CCL2/CCR2 axis in tumor progression and develop more effective anti-tumor immunotherapeutic agents.

Objective To compare the effects of remifentanil infused at different rates on median effective target plasma concentration (EC50) of propofol inhibiting responses to laryngeal mask airway (LMA) insertion and determine the optimum infusion rate of remifentanil when used for fiberoptic bronchoscopy in pediatric patients.Methods Eighty-four ASA Ⅰ or Ⅱ pediatric patients,aged 7 months-3 years,scheduled for elective fiberoptic bronchoscopy,were randomly assigned into 3 groups (n =28 each):normal saline group (group C),remifentanil infused at 3 ng· kg-1 ·min-1 group (group R1) and remifentanil infused at 5 ng· kg-1 · min-1 group (group R2).Responses to LMA insertion were defined as body movement and/or bucking during insertion.The initial target plasma concentrations of propofol were 5.2,4.8 and 4.4 μg/ml in groups C,R1 and R2,respectively.The target plasma concentration of propofol was determined by up-and-down sequential allocation.Each time the target plasma concentration increased/decreased by 0.2μg/ml.EC50 and 95 ％ confidence interval of propofol blunting responses to LMA insertion were determined by probit method.Results EC50 (95 ％ confidence interval) of propofol was 5.03 (4.92-5.12) μg/ml,4.71 (4.58-4.84) μg/rnl and 4.46 (4.20-4.94) μg/ml in groups C,R1 and R2,respectively.There was no significant difference in EC50 of propofol between groups R1 and C (P ＞ 0.05).EC50 of propofol was significantly lower in group R2 than in groups C and R1 (P ＜ 0.05).Conclusion The infusion rate of remifentanil should not be lower than 5 ng· kg-1· min-1 when combined with propofol in pediatric patients undergoing fiberoptic bronchoscopy.

Objective: To evaluate the intervention effect of clinical pharmacists in hypertension chronic disease management. Methods:All the patients with hypertensive chronic diseases from Ziyang community, Xingan Street, Beilun district were involved in the study. Combined with community doctors, clinical pharmacists provided pharmaceutical care for the patients, such as regular face-to-face medication guide, telephone communication, home follow-up, special lectures on health and so on.
