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.

The aim of this study was to study the synthesis of two folate conjugates and their application in the preparation of folate targeted liposome, and to investigate their targeting effect in hepatocellular carcinoma HepG2 cell line in vitro. In this study, Folate-PEG-Cholesteryl hemisuccinate(Folate-PEG2000-CHEMS and Folate-PEG4000-CHEMS)were synthesized by linking folate and cholesterol succinate with two kinds of PEG materials. Structures of Folate-PEG2000-CHEMS and Folate-PEG4000-CHEMS were characterized by 1H NMR and ultra-high resolution mass spectrometry. Calcein was selected as the model drug, and calcein liposomes FA-PEG2000-L and FA-PEG4000-L were prepared by film dispersion method using Folate-PEG2000-CHEMS and Folate-PEG4000-CHEMS, respectively. The particle size and Zeta potential of FA-PEG2000-L and FA-PEG4000-L were measured by laser particle size analyzer. The drug delivery effect of FA-PEG2000-L and FA-PEG4000-L was evaluated by cellular uptake experiment in HepG2 cell line in vitro. Flow cytometry and laser confocal scanning microscope were used to determine fluorescence in HepG2 cells in vitro. The results showed that the average particle size of calcein liposome was (205.8 ± 10.2) nm, and the Zeta potential of calcein liposome was -(1.19 ± 0.31) mV.There was no significant difference in particle size and Zeta potential between FA-PEG2000-L and FA-PEG4000-L. The fluorescence intensity of FA-PEG4000-L liposome group was about 3.6 and 3.1 times higher than that of non-targeted liposome group and FA-PEG2000-L liposome group, with statistically significant difference (P < 0.01). The drug delivery efficiency of FA-PEG4000-L group in HepG2 cells was higher than that in FA-PEG2000-L and non-targeted groups, and the results indicated that Folate-PEG4000-CHEMS can promote the uptake of liposome by HepG2 cells in vitro. All in all, Folate-PEG4000-CHEMS could be applied in the preparation of folate targeted liposome, which could promote the uptake of liposome by HepG2 cells.

Alzheimer's disease ( AD ) is a complex disease caused by environmental and genetic factors. Therefore, one-drug-multiple-target compounds represent the most promising pharmacological approaches to preventing and treating this dis-ease. We have previously designed and synthesized bis( n)-Cog-nitin, novel anti-Alzheimer's dimers derived from tacrine. Bis ( n)-Cognitin have been proven to act on multiple important AD targets, including acetylcholinesterase, β-secretase, N-methyl-D-aspartic acid receptor and neuronal nitric oxide synthase, con-currently. Moreover, Bis(n)-Cognitin could inhibit β-amyloid-induced neurotoxicity, decrease glutamate-induced excitotoxici-ty, reduce oxidative stress, improve learning and memory, and protect against neuronal apoptosis in various in vitro and in vivo models, suggesting that bis ( n )-Cognitin are potential anti-AD drug candidates.

Objective To investigate the risk factors and the influence of intravenous thrombolysis of acute cerebral infarction with cerebral microbleeds(CMBs)by SWI.Methods 1 64 patients with acute cerebral infarction were enrolled in this study.All pa-tients were scanned with routine MRI and SWI.According to the presence of CMBs on SWI,the patients were classified into two groups:CMBs group(73 cases)and non-CMBs group(91 cases).Past history was recorded and risk factors of CMBs were explored. 76 cases patients(including 35 cases of CMBs group and 41 cases of non-CMBs group)were treated by intravenous thrombolysis and rescanned with routine MRI and SWI to compare the changes in the number of CMBs and hemorrhage transformation 24 hours after thrombolysis.Results The difference age,hypertension,lacunar infarction and leukoaraiosis between the two groups were significant (P <0.05).The difference of CMBs and hemorrhagic transformation between the two groups treated by thrombolysis were not sig-nificant(P >0.05).Conclusion Acute cerebral infarction with CMBs are influenced by age,hypertension,lacunar infarction and leu-koaraiosis.Thrombolysis in acute cerebral infarction with CMBs can not augment the incidence of hemorrhagic transformation.

METHODS:A computer-based search of PubMed and NCBI databases was performed for literatures about the research progress of electrospinning in tissue engineering and chemotherapy published within the past 10 years using the keywords of“electrospinning, drug delivery system, nanofibers, electrospun materials”.RESULTS AND CONCLUSION:Compared with traditional materials, electrospun stents hold good versatility and control able parameters, thus granting its unique advantage under various physiological conditions. Current drug-loaded materials composed of natural products, synthetic polymers and blended materials;as to drugs, there are antibiotics, chemotherapy medication, DNA and protein. Electrospun materials have been used in tissue engineering, cancer chemotherapy and wound healing.

Electrospun materials combined with various drug-loaded present a broad prospect.

In this study, the conjugate of eicosapentaenoic acid (EPA) and hyaluronic acid (HA) was synthesized and the anti-hepatoma activities in vitro were evaluated.The hyaluronic acid-eicosapentaenoic acid (HA-EPA)nanoparticle was synthesized by linking eicosapentaenoic acid with hyaluronic acid with cystamine.The structure of HA-EPA was characterized by nuclear magnetic resonance (1H NMR) and Fourier transform infrared spectroscopy (FT-IR).Laser particle sizer and Zeta potential analyzer were used to detect the size and potential of HA-EPA.MTT assay was used to detect the anti-proliferative effect of HA-EPA on HepG2, Huh-7 and LX-2 cells in vitro.The effects of HA-EPA nanoparticles on the proliferation and apoptosis of HepG2 cells in vitro were investigated by EdU staining and TUNEL staining. The apoptosis was further confirmed by flow cytometry.The effect of HA-EPA nanoparticles on the migration and invasion of HepG2 cells was demonstrated by transwell and invasion experiments.The results of 1H NMR showed that HA-EPA was successfully synthesized, and the grafting rate of EPA on HA was (40 ± 5) %. The structure of HA-EPA was further confirmed by FT-IR.The particle size was (162.5 ± 10.2) nm, and the potential was -(4.47 ± 0.31) mV.MTT results showed that, with the prolongation of drug treatment time, HA-EPA showed a better inhibitory effect on the activity of HepG2 and Huh-7 cells than EPA under the same EPA content.After treated for 48 hours, the toxicity of HA-EPA to LX-2 cells was less than that of EPA.The results of 24-hour proliferation, apoptosis, migration and invasion of HepG2 showed that, the graft of hyaluronic acid improved the ability of EPA to inhibit proliferation, promote apoptosis, migration and invasion of HepG2 cells (P < 0.001), indicating that grafting of HA can significantly enhance the inhibitory effect of EPA on liver cancer with some role in reducing toxicity.
