[ ABSTRACT] AIM:To investigate the inhibitory effect of ginsenoside Re on intimal hyperplasia induced by bal-loon-injury and to explore the role of NF-κB p65 signaling pathway in the process.METHODS:SD rats (n=40) were di-vided into 5 groups randomly: sham operation group, model group, low-dose ginsenoside Re group, middle-dose ginsen-oside Re group and high-dose ginsenoside Re group.The carotid artery intima injury model was established by 2F balloon catheters in all groups except the sham operation group.The day after modeling, the animals in model group and sham op-eration group were administered intragastrically with distilled water, and the rats in low-dose, middle-dose and high-dose ginsenoside Re groups were given ginsenoside Re at doses of 12.5 mg/kg, 25mg/kg and 50 mg/kg, respectively.After 14 continuous days, the morphological changes of the injured arteries were observed by HE staining and the lumen area, intima area and media area as well as the ratio of intimal area/media area were determined.The expression of tumor necrosis fac-tor-α( TNF-α) and interleukin-1β( IL-1β) were detected by real-time PCR.The proliferating cell nuclear antigen ( PC-NA) and nuclear factor-kappa B ( NF-κB) p65 were examined by immunohistochemistry.RESULTS:Compared with sham operation group, the vessel cavity was narrowed (P<0.01), the mRNA levels of TNF-αand IL-1β, and the protein ex-pression of PCNA and NF-κB p65 were increased in model group (P<0.05).Compared with model group, the vascular intimal hyperplasia was alleviated obviously (P<0.05), and the mRNA levels of TNF-αand IL-1β, and protein expres-
sion of PCNA and NF-κB p65 were decreased in medium and high-dose ginsenoside Re groups (P<0.05).CONCLU-SION:Ginsenoside Re inhibits the vascular neointimal hyperplasia induced by balloon-injury in rats, and the molecular mechanism may be related to the inhibition of NF-κB p65 signaling pathway.

BACKGROUND: A large number of preclinical experimental data have shown that stem cells can regulate the immune function, and serve the function of cell replacement. OBJECTIVE: To summarize the anti-inflammatory effects of stem cells in the treatment of ischemic stroke, based on which, we further discuss the specific mechanisms. METHODS: We conducted a systematic and comprehensive search in PubMed, Elsevier, Springer, Wiley, Ovid, EBSCO databases. The range of retrieval time was from 2012 to 2017. The keywords were stem cells, stroke, inflammation, immune. Totally 110 articles were retrieved initially, and 47 articles were included in result analysis. RESULTS AND CONCLUSION: By reading extensive literature, we analyzed and summarized the research status quo of the anti-inflammatory effects of neural stem cells, mesenchymal stem cells and endothelial cells in the treatment of ischemic stroke. The mechanisms mainly include reducing focal inflammation, immune regulation, promoting the secretion of various neurotrophic factors, reducing secondary cell death, protecting neurons and promoting cell function recovery and further promoting the recovery of nerve function. The mechanisms underlying local immune regulation and anti-inflammatory effects of stem cells are mainly described as the shift from M1 to M2 macrophages under the intervention of stem cell factors, to intervene secreted immune cytokine profiles and exert effects on inhibition and polarization of glial cells. Further investigation is required on the anti-inflammatory effects and immune regulation of stem cell therapy for stroke.

Objective To investigate the association of monocyte chemoattractant protein-1 (MCP-1) promoter -2518A/G gene polymorphism with coronary lesions and in stent restenosis in Tianjin Chinese population. Methods Two hundred and seventy six patients who underwent percutaneous coronary intervention (PCI) and coronary angiography during follow-up were enrolled in the study. The MCP-1 gene promoter polymorphism at position -2518 was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results The frequencies of three genotypes of MCP-1-2518A/G polymorphism were 21.0% AA, 34. 1% GG,44.9% AG, respectively. There were no statistical differences in the number and the mean degree of stenosis vessels before PCI among 3 genotype groups (all P>0.05). 113 cases developed in-stent restenosis and 163 cases were free from restenosis. In restenosis group, the AA, AG and GG genotype frequencies were 23.9%, 40.7%, 35.4%, against 19.0%, 47.9% and 33.1% in nonrestenosis group (P = 0. 446) . The frequencies of -2518A and G allele were 44.2%, 55.8% in restenosis group versus 42.9%, 57. 1% in non-restenosis group(P=0. 761). Conclusions The polymorphism of MCP-1-2518 A/G gene may be associated with neither atherosclerosis nor the in-stent restenosis.

9.Technological progress in intraoperative rapid identification of the parathyroid glands
Chinese Journal of Clinical Oncology 2019;46(9):480-484
Hypoparathyroidism is an important complication of thyroidectomy. Identification of the parathyroid glands during thyroid-ectomy may be the first step for preserving these organs and preventing the loss of their function. Generally, surgeons can confirm parathyroid tissues based on frozen biopsy during thyroid surgery; however, this method can lead to vascular damage as a result of cut-ting part of the parathyroid glands and is associated with additional cost and waiting time. To identify the parathyroid gland more con-veniently, quickly, and accurately during thyroid surgery, some novel techniques have been developed. In this article, current studies that describe intraoperative rapid in situ identification of the parathyroid glands are reviewed.
