Sphingosine-1-phosphate (S1P) is a lysophospholipid signaling molecule that regulates important biological functions in both intracellular and extracellular compartments. It interacts with five G protein-coupled receptors subtypes (S1PR(1-5)) to generate multiple downstream signaling. Activation of S1PR1 has been validated to be involved in the process of immune modulation. Fingolimod (FTY720), the novel S1PR1 agonist, has been approved for the treatment of multiple sclerosis in clinical trials. The study towards discovery of selective S1PR1 agonists has become hot spot for immunological diseases. This article summarized the research progress of S1PR1 agonists, emphasizing their structure types, structure-activity relationship and direction of development.

Objective:To investigate the clinical efficacy of intramedullary nailing combined with bone cement in repair of segmental bone defects after tumor resection.Methods:A retrospective analysis was conducted of the 5 patients with malignant bone tumor who had been treated at Department of Orthopaedics, Qiannan People's Hospital from April 2018 to September 2019 for remaining segmental bone defects following limb salvage surgery. They were 4 males and one female, aged from 11 to 55 years (average, 35.4 years). Their defects ranged from 6 to 21 cm (average, 12.3 cm) after tumor resection. By the Karnofsky performance score (KPS) for long-term quality of life, all of them scored less than 50 points. Of them, 3 were treated by interlocking intramedullary nails and bone cement filling, and 2 by elastic intramedullary nails and bone cement filling. In the 2 cases with defects of 21 cm and 13 cm, the fixation was assisted by a plate and an external fixator. Defect length after resection, operation time and intraoperative bleeding were recorded; the efficacy was evaluated by the Enneking functional evaluation of reconstructive procedures after surgical treatment of tumors of the musculoskeletal system, visual analogue scale (VAS), and KPS.Results:All the 5 patients had uneventful surgery, with operation time ranging from 112 to 225 min (average, 154.2 min), intraoperative bleeding from 300 to 500 mL (average, 382 mL), and defect length after resection from 6 to 21 cm. The 5 patients were followed up for 6 to 28 months. Of them, 2 died of disease progression 6 and 7 months after surgery, respectively. According to the Enneking's evaluation, one patient scored 28 points, 2 patients 23 points and 2 patients 21 points, giving a high degree of satisfaction. Their VAS scores 6 months after surgery ranged from 1 to 6, averaging 3.6; their postoperative KPS scores ranged from 60 to 80, averaging 72.Conclusion:In repair of segmental bone defects after tumor resection, intramedullary nailing combined with bone cement filling can relieve pain of patients and lead to satisfactory short-term curative efficacy.

Objective To investigate the expression and significance of Periostin,VEGF and MMP-9 in breast invasive ductal carcinoma.Methods Immunohistochemistry was employed to detect the expression of Periostin,VEGF and MMP-9 in breast invasive ductal carcinoma and normal breast tissue.Results In breast invasive ductal carcinoma and normal breast tissue,the positive rates of Periostin were 63.8 ％ (37/58) and 0 (x2 =24.272,P =0.000).The figures were 69 ％ (40/58) and 8 ％ (2/25) for the positive rates of VEGF (x2 =25.977,P =0.000),respectively,as well as 70.69 ％ (41/58) and 16.0 ％ (4/25) for the positive rates of MMP-9 (x2 =21.050,P =0.000),respectively.There were significant differences among the groups (P ＜ 0.05).In breast invasive ductal carcinoma,the expression of Periostin was correlated with clinical stage (x2 =4.835,P =0.028),whereas not correlated with age (x2 =1.155,P=0.282),histological grade (x2 =0.05,P =0.972),lymphatic metastasis (x2 =1.660,P =0.198).The expression of VEGF was correlated with clinical stage (x2 =4.230,P =0.040),lymphatic metastasis (x2 =9.667,P =0.002),whereas not correlated with age (x2 =0.506,P =0.477),histological grade (x2 =0.532,P =0.767).The expression of MMP-9 was correlated with clinical stage (x2 =8.456,P =0.004),lymphatic metastasis (x2 =5.494,P =0.019),whereas not correlated with age (x2 =0.153,P =0.695),histological grade (x2 =0.224,P =0.894).The expression of Periostin,VEGF and MMP-9 were positively correlated with each other in breast invasive ductal carcinoma (r =0.348,P =0.001; r =0.303,P =0.021; r =0.469,P =0.000).Conclusion Periostin,VEGF and MMP-9 are correlated closely with the occurrence and development of breast invasive ductal carcinoma,which might be valuable in evaluating the invasiveness,metastasis and prognosis.

To investigate the role of AQP9 in brain edema, the expression of AQP9 in an infectious rat brain edema model induced by the injection of lipopolysaccharide (LPS) was examined. Immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR) analysis demonstrated that the expressions of AQP9 mRNA and protein at all observed intervals were significantly increased in LPS-treated animals in comparison with the control animals. Time-course analysis showed that the first signs of blood-brain barrier disruption and the increase of brain water content in LPS-treated animals were evident 6 h after LPS injection, with maximum value appearing at 12 h, which coincided with the expression profiles of AQP9 mRNA and protein in LPS-treated animals. The further correlation analysis revealed strong positive correlations among the brain water content, the disruption of the blood-brain barrier and the enhanced expressions of AQP9 mRNA and protein in LPS-treated animals. These results suggested that the regulation of AQP9 expression may play important roles in water movement and in brain metabolic homeostasis associated with the pathophysiology of brain edema induced by LPS injection.

Objective:The purpose of this study is to determine levels of Ghrelin,TNF-α,IL-1 and IL-6 in peripheral blood of patients with chronic hepatitis B,liver cirrhosis,and non-alcoholic fatty liver disease which diagnosed at different extent of damage,and based on it to have a further study on the relevance between Ghrelin and inflammatory cytokines in peripheral blood in above diseases.Methods:Ghrelin,TNF-α,IL-1 and IL-6 in peripheral blood were determined by ELISA method.Results:In patients with chronic hepatitis B andhepatic cirrhosis,Ghrelin level increased significantly as compared with that in normal control group (P＜0.05,P＜0.01).Ghrelin levels in decompensated liver cirrhosis (degree B and C)groups were much higher than in chronic hepatitis B group (P＜0.05). Ghrelin level in group of non-alcoholic fatty liver disease decreased significantly as compared with that in normal control group (P<0.01). Ghrelin and inflammatory cytokines,including TNF-α,IL-1 and IL-6 showed a positive relevances in groups of chronic hepatitis B and liver cirrhosis,but not in NAFLD group which showed a negative correlations.Conclusion:Ghrelin has a higher level in peripheral blood of patients with chronic hepatitis B and liver cirrhosis,but it has a lower level in patients with non-alcoholic fatty liver disease,suggesting correlation of Ghrelin level with the occurrence and the procession of chronic liver diseass.

The expressions of estrogen receptor (ER) α,ERβ1,and ERβ2 in thyroid carcinoma,thyroid adenoma,and adjacent normal thyroid tissue were determined by RT-PCR and immunohistochemistry,and the relationship of expression levels of three ERs and the main clinical pathologic parameters were evaluated.The result showed that ERα mRNA expression in papillary thyroid carcinoma(PTC) tissues was significantly higher than adjacent normal tissue,while,ERβ2 mRNA expression in PTC tissues was significantly lower than normal tissue ( P＜0.05 ).The positive expression of ERβ1 and ERβ2 in the thyroid carcinoma was related with the histological variant of carcinomas; the ERβ2 expressions were related with the lymph node metastasis and TNM staging of the carcinomas.These results suggest that the decreased ERβ2 expression may induce proliferation and carcinogenesis of thyroid follicular epithelial cells as well as progression of the carcinoma,and is a powerful prognostic indicator.

Objective investigate the correlation between plasma soluble receptor for advanced glycation endproducts (sRAGE) and arterial stiffness in patients with different types of metabolic syndrome (MS).Methods A total of 180 subjects were drawn from a epidemiologic follow-up study,including 60 cases non-metabolic syndrome (NMS),60 cases metabolic syndrome without diabetes mellitus (NDMMS),60 cases metabolic syndrome with diabetes mellitus (DMMS).Carotid femoral arterial pulse wave velocity (CFPWV) was assessed by the French KangPuLe atherosclerosis measurement instrument,and plasma sRAGE levels were measured by ELISA.Comparison of mean in multiple groups was conducted by analysis of variance.Multivariate analysis was done with multiple linear stepwise regression analysis.P ＜ 0.05 was considered as statistically significant difference.Results Compared with NMS group,plasma sRAGE levels were significantly lower in DMMS and NDMMS groups [(635.07 ± 229.20) pg/mL vs.(671.17 ± 358.16) pg/mL vs.(992.99 ± 427.83) pg/mL,P =0.001].CFPWV of DMMS group was significantly higher than that of NMDMS and NMS groups (14.22 ±3.14) m/s vs.(12.15 ±2.79) m/s vs.(11.66 ± 2.52) m/s,P =0.002).Plasma sRAGE level was negatively correlated with CFPWV (r =-0.278,P =0.005).(3) Multiple linear regression analysis demonstrated that age (β =-0.091,95％ CI-0.096 ～-0.095,P =0.031),HDL-C (β =1.295,95％ CI 1.231 ～ 1.360,P =0.022) and sRAGE (β =0.119,95％ CI 0.118 ～ 0.130,P =0.032) had a significant effect on CFPWV.Conclusions The increased arterial stiffness is closely related to the discreased plasma sRAGE levels in MS.Plasma sRAGE maybe a novel target for vascular disease prevention and treatment in patients with metabolic syndrome.
