1.Advance in treatment of hyperuricemia by Chinese medicine based on uric acid transporterome.
China Journal of Chinese Materia Medica 2015;40(22):4346-4350
With the development of the quality of life, the morbidity of hyperuricemia is increasing year by year. At the same time, it appears that this disease attacks the young people currently. As the study of pathogenesis of hyperuricemia advanced, a series of uric acid transporters were found during this process. Meanwhile, the definition of transporterome was proposed. They were divided into three groups according to the functions: reabsorption proteins, excretion proteins and skeleton proteins. At moment, the drugs for hyperuricmia mainly include uric acid composition inhibitors and uric acid excretion promoters. Since the excretion of uric acid plays a leading role during the process of attack of hyperurecimia, it makes sense to explore Chinese medicines with clear mechanism targeting the transporterome. Therefore, this paper would focus on transporterome and summarize the mechanisms of Chinese medicines in treating hyperuricemia.

OBJECTIVETo study the effect of total saponins from Rhizoma Dioscoreae nipponicae (RDN) on the expression of stroma cell derived factor 1 (SDF1) and IKB kinase (IKK) in rIL-1beta induced fibroblast-like synoviocytes (FLS).
METHODSFLS were primarily cultured and the 3rd generation log phase growth FLS were divided into the normal control group, the model group, and the medication group. 10 microg/L rIL-1beta was used to induce the proliferation of FLS in the model group.10 microg/L rIL-1beta and 100 microg/L RDN were administered to co-incubate FLS in the medication group. No treatment was given to FLS in the normal control group. Expression levels of SDF1 and IkapaB kinase proteins (p-IKK) were detected using Western blot.
RESULTSExpression levels of SDF1 and p-IKK increased significantly higher in the model group than in the normal control group (P<0.01). Compared with the model group, expression levels of SDF-1 and p-IKK significantly decreased in the medication group (P <0.01).
CONCLUSIONSTotal saponins from RDN could inhibit the activation of both SDF1 and p-IKK. It might further regulate the expression of IKB kinase by regulating the expression of SDF1.

Objective To explore the prognostic value of biomarkers in type 2 diabetic patients with acute myocardial infarction (AMI), this study was to investigate the associations between the neutrophil to lymphocyte ratio (NLR), the Global Registry of Acute Coronary Events (GRACE) score and in-hospital mortality. MethodsSeven hundred and seven consecutive AMI patients were divided into diabetic group (DM-AMI group), impaired glucose tolerance group (IGT-AMI group), and normal glycemic group (NGT-AMI group). The laboratory and clinical characteristics were assessed retrospectively from the medical records. The NLR and GRACE score were calculated. Results In AMI patients, the DM-AMI group had significantly higher NLR and GRACE scores compared with those from the IGT-AMI group and NGT-AMI group (P<0.01 or P<0.05). In DM-AMI group, the NLR and GRACE score were considerably elevated in the elderly DM-AMI group compared with their younger counterparts (both P<0.01). Furthermore, the NLR was considerably higher in the high-risk group than those in both the low- and medium-risk groups based on the GRACE score (both P<0.01). The NLR was positively correlated with the GRACE score in DM-AMI group(r=0.425, P<0.01). The NLR level and GRACE score were higher in the death group than those in surviving patients (both P<0.01). The optimal cut-off levels of 9.36 for NLR and 166 for GRACE score seem to predicte death in-hospital. Based on the receiver operating characteristic curve, when to predict death in-hospital, the best cutoff value of NLR was 9.36 (sensitivity 80.8%, specificity 69.6%; area under curve 0.787), and the best cutoff value of GRACE score was 166 (sensitivity 76.9%, specificity 76.4%; area under curve 0.778). Conclusion An elevated NLR is a potential predictor of in-hospital mortality in type 2 diabetic patients with AMI, which could help clinicians indentify high-risk patients and determine appropriate treatment strategies. <英文关鍵词>>=Neutrophil to lymphocyte ratio; In-hospital mortality; Acute myocardial infarction; Diabetes mellitus, type 2

Objective To study the function of vascular endothelial growth factor (VEGF) in type 2 diabetes model rats and its effect on focal cerebral ischemia induced by middle cerebral artery occlusion in these rats. Methods Focal cerebral ischemia was induced by middle cerebral artery occlusion for 6 hours in type 2 diabetes rats and normal control rats.Blood vessels morphology was examined by ink perfusion,infarct size was measured by TTC and expression of VEGF and CD34 were evaluated by immunohistochemistry staining. Results Ink perfusion revealed increased number of small vessels in type 2 diabetes rats. Infarct size was significantly smaller in type 2 diabetes rats ( ( 80. 07 ± 11.21 ) mm3 ) than that in normal controls ((98. 91 ± 14. 86) mm3,t = 2.48,P = 0. 0326). There were more hemorrhage lesions in the ischemic hemisphere in type 2 diabetes rats when comparing with the controls. VEGF and CD34 showed significantly higher expression in type 2 diabetes rats than in normal controls. Conclusions High expression of VEGF and CD34 are found in type 2 diabetes rats after middle cerebral artery occlusion. There is cerebrolvascular remodeling in diabetes rats. While this diabetes-induced remodeling appears to prevent infarct expansion,the changes also increase the risk of hemorrhagic transformation. The latter may result in poor prognosis.
