Protective effects of isorhamnetin on apoptosis and inflammation in TNF-α-induced HUVECs injury

Little is known about the role of isorhamnetin on endothelial cell apoptosis and inflammation when insulted by TNF-α injury. In our study, HUVECs were treated with TNF-α for 6 hours. HUVECs apoptosis were detected using flow cytometry. The expressions of ICAM-1, VCAM-1, E-selectin, NF-κB, AP-1 and eNOS were determined with western blotting or flow cytometry. The results showed TNF-α increased of apoptosis and the expression of ICAM-1, VCAM-1 and E-selectin in HUVECs, accompanied by significant augmentation of NF-κB and AP-1 expression. Pretreatment with isorhamnetin significantly reduced apoptosis in TNF-α-treated HUVECs. Moreover, isorhamnetin significantly attenuated TNF-α-induced upregulation of ICAM-1, VCAM-1, AP-1, E-selectin and NF-κB expression. Meanwhile, isorhamnetin also increased the expression of eNOS. So, isorhamnetin could suppress TNF-α-induced apoptosis and inflammation by blocking NF-κB and AP-1 signaling in HUVECs, which might be one of the underlying mechanisms for treatment of coronary heart disease.

The influence of exercise training versus intensive insulin therapy on insulin resistance development in type 1 diabetes

The etiology of insulin resistance (IR) in Type 1 Diabetes (T1D) is unclear; however, intramyocellular lipids (IMCL) are likely contributors. While exercise lessens IR and IMCL content; T1D patients elevate glycemia to offset exercise-induced hypoglycemic risk. The preferred treatment for T1D patients is tight glucose management through intensive insulin therapy (IIT); however, IIT is accompanied with a sedentary lifestyle. The purpose of this study was to examine IR development and IMCL in combined exercise (DARE; aerobic/resistance) and IIT-treated T1D animals. 76 rats were divided into control sedentary (C), diabetic sedentary (CD), diabetes sedentary intensive insulin therapy (DIT) and DARE groups. Following streptozotocin (STZ), glycemia was maintained at either 9-15 mM (CD, DARE) or 5-9 mM (DIT) using insulin. DARE alternated between running and weighted climbing for 12 weeks. Results demonstrate that DARE exhibited reduced onset of IR compared with C, DIT and CD, indicated by increased glucose infusion rate (hyperinsulinemic-euglycemic-clamp). A shift in lipid metabolism was evident whereby diacylglycerol was elevated in DIT compared to DARE, while triacylglycerol was elevated in DARE. These findings indicate enhanced IMCL metabolism and the sequestration of fat as neutral triacylglycerol leads to reduced IR in DARE. In contrast, IIT and sedentary behavior leads to diacylglycerol accumulation and IR.

火针点刺承泣穴治疗周围性面瘫后遗溢泪症的临床观察

ObjectiveTo compare the clinical therapeutic effect on epiphora as sequela of peripheral facial paralysis treated with pricking technqiue of fire needling therapy at Chéngqì (承泣 ST1) and acupuncture treatment at conventional acupoints.MethodsFrom September 2018 through to October 2018, 64 cases of epiphora as sequela of peripheral facial paralysis were collected from the Department of Acupuncture-Moxibustion in Suzhou TCM Hospital. According to random number table, they were divided into an observation group and a control group, 32 cases in each one. In the observation group, pricking technique of fire needling therapy was used at ST1, once every two days. In the control group, acupuncture with filiform needle was applied to Jīngmíng (睛明BL1), Tàiyáng (太阳EX-HN5), Tóngzĭliáo (瞳子髎GB1), Sìbái (四白ST2) and Quánliáo (颧髎SI18) on the affected side as well as Hégŭ (合谷LI4) on the contralateral side, once per day. The 10-day treatment was as one 1 course and the consecutive 3 courses of treatment were required in either of the groups. Before and after treatment, Munk grade, clinical effective rate and the number of treatments were observed in the evaluation of therapeutic effect.ResultsAfter treatment, Munk grade was improved in the patients of the two groups (both P < 0.05). The improvement range in the observation group was larger than that of the control group (P < 0.05). The treatment in either group achieved the obviously therapeutic effect on epiphora as sequela of peripheral facial paralysis. The effective rate in the observation group was 90.32%, higher than 61.29% in the control group (P < 0.05). The mean number of treatments of the curative case were 5.11 in the observation group and were 13.73 in the control group, indicating the statistical significance in difference (P < 0.05).ConclusionPricking technique of fire needling therapy at ST1 achieves the better effect on epiphora as sequela of peripheral facial paralysis as compared with acupuncture at conventional acupoints.     

Xanthatin,a novel potent inhibitor of VEGFR2 signaling,inhibits angiogenesis and tumor growth in breast cancer cells

Anti-angiogenesis targeting vascular endothelial growth factor receptor 2 (VEGFR2) has emerged as an important tool for cancer treatment. In this study, we described a novel VEGFR2 inhibitor, xanthatin, which inhibits tumor angiogenesis and growth. The biochemical profiles of xanthatin were investigated using kinase assay, migration assay, tube formation, Matrigel plug assay, western blot, immunofluorescence and human tumor xenograft model. Xanthatin significantly inhibited growth, migration and tube formation of human umbilical vascular endothelial cell as well as inhibited vascular endothelial growth factor (VEGF)-stimulated angiogenesis. In addition, it inhibited VEGF-induced phosphorylation of VEGFR2 and its downstream signaling regulator. Moreover, xanthatin directly inhibit proliferation of breast cancer cells MDA-MB-231. Oral administration of xanthatin could markedly inhibit human tumor xenograft growth and decreased microvessel densities (MVD) in tumor sections. Taken together, these preclinical evaluations suggest that xanthatin inhibits angiogenesis and may be a promising anticancer drug candidate.
