OBJECTIVE:To investigate clinical efficacy of intravenous drip of alprostadil combined with acupuncture in the treatment of diabetic foot ulcer and its effects on inflammatory factors levels and wound microvascular density. METHODS:A total of 72 patients with diabetic foot ulcer in our hospital during May 2014 to Sept. 2015 were divided into observation group and con-trol group according to random number table,with 36 cases in each group. Control group was given Alprostadil injection 10μg add-ed into 250 mL 0.9% Sodium chloride injection intravenously,qd,on the basis of routine treatment as insulin. Observation group was additionally given acupuncture therapy (Sanyinjiao,Zusanli,Fenglong,Yanglingquan,Yinlingquan and other acupuncture points),qd,on the basis of control group. Treatment courses of 2 groups lasted for 3 weeks. Clinical efficacy,wound healing time,fasting blood glucose,urine microalbumin,inflammatory factors,wound microvascular density as well as the occurrence of ADR were compared between 2 groups. RESULTS:The total response rate of observation group(91.67%)was significantly higher than that of control group(72.22%),and wound healing time was significantly shorter than control group,with statistical signifi-cance(P<0.05). Before treatment,there was no statistical significance in fasting blood glucose,urine microalbumin and inflamma-tory factors between 2 groups (P>0.05). After treatment,above indexes of 2 groups were significantly lower than before,and urine microalbumin and inflammatory factors of the observation group was significantly lower than the control group,with statisti-cal significance (P<0.05). 14,21 d after treatment,wound microvessel density of observation group was significantly higher those of control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Intrave-nous drip of Alprostadil combined with acupuncture can boost angiogenesis through mitigating inflammatory reactions,thus shorten the time of wound healing and enhance therapeutic efficacy.

T2DM+LIRA group and T2DM+LIRA+UC-MSCs group (P<0. 05). The ratio of insulin positive area in pancreas tissue was obviously rised, while the ratio of glucagon positive area in pancreas tissue was clearly descended in T2DM+LIRA+UC-MSCs group. And the same difference in valuating islet cells apoptosis by TUNEL could be observed ( P<0. 05). The expression of NF-κB and TLR4 protein in pancreas tissue of T2DM+LIRA+UC-MSCs group were the least amongthefourgroups[(0.75±0.10)vs(0.60±0.08),(0.47±0.08),(0.31±0.04),P<0.05]and[(1.24± 0. 12) vs (0. 93 ± 0. 10), (0. 95 ± 0. 09), (0. 74 ± 0. 07), P<0. 05 ]. Conclusion The combined treatment of liraglutide with umbilical cord mesenchymal stem cells is superior over a single treatment of liraglutide or umbilical cord mesenchymal stem cells in improving the islet function in type 2 diabetes mellitus models, which may be related to the down modulating the TLR4/NF-κB inflammatory signaling pathway.

Background Glial cells perform specialized function in many aspects of the development,homeostasis,and function of neurons.Retinal ganglion cells (RGCs)and glia interactions are critically important in glaucomatous neurodegeneration.However,the precise mechanisms of glial activation and ganglion cells damage are still remained unclear. Objective This study was to assess the early responses of glial cells in the retina,optic nerve and optic chiasm in rat models of acute high intraocular pressure (IOP),and to examine the expression of nestin,a neuronal progenitor marker,in the reactive glias. Methods Acute high IOP of 110 mmHg was induced in the right eyes of 6 clean adult female Wistar rats by infusing normal saline solution into the anterior chamber for 60 minutes.Three normal matched Wistar rats were used as controls.The rats were sacrificed by overanaesthesia and sections of retina,optic nerve and optic chiasm were collected on 3 days and 7 days after the injection.Rat retina was examined by Nissl staining to illustrate the gross structure changes.Loss of axons of RGCs in the optic nerve was assessed by immunostaining of β Ⅲ-tubulin.Double labeling of glia] fibrillary acidic protein (GFAP) and nestin was performed in sections of retina,optic nerve and optic chiasm to evaluate the glial responses.The use of the animals complied with Statement of Animal Ethic Committee of Peking University Third Hospital. Results In control rats,GFAP-positive glial cells were observed in the retina,optic nerve and optic chiasm,where only weak positive response for nestin was noticed.Three days after acute IOP elevation,thickness of inner plexus form layer was significantlydecreased in comparison with the control rats.A loss of 46% RGCs was found in the rats with ocular hypertension.Obvious increase of GFAP expression was displayed in the retina,and processes of GFAP-positive glia cells extended into outer retina accompanied with significant up regulation of nestin.Axons in the optic nerve demonstrated a tendency of degeneration.Nestin expression increased significantly in the GFAP-positive glias in the optic nerve.Cross-sectional area of optic chiasm corresponding to the injured retina decreased relative to its countcrpart.Astrocyte like GFAP and nestin-colabeled glials were observed in this part of optic chiasm.The pathological changes of the retina,optic nerve and optic chiasm in hypertensive eyes aggravated on 7 days. Conclusions Acute ocular hypertension induce early onset of RGCs loss and axon degeneration.Neuronal injury is accompanied with glial reaction.Reactive glial cells express neuronal progenitor markers.The structural changes of the optic nerve and optic chiasm occur simultaneously with the high IOP.
