Objective:To evaluate the effects of rapamycin on the proliferation,apoptosis and cell cycle of glomerular mesangial cells induced by high glucose,and to explore its significance in the prevention and treatment of diabetic nephropathy. Methods:The rat GMC HBZY-1 was divided into four groups:control group,high glucose group,the first group of high glucose plus rapamycin,the second group of high glucose plus rapamycin. CCK-8 assay was used to detect the proliferation of cells, flow cytometry was introduced to evaluate the apoptosis and cell cycle of HBZY-1,Real-time PCR was used to detect the mRNA of AngiotensinⅡ(ANGⅡ),transfor ming growth factor beta1 ( TGF-β1 ) and vascular endothelial growth factor ( VEGF ) . Results: The proliferation level of HBZY-1 induced by high glucose was significantly increased,and the level of apoptosis decreased,and the expression level of ANGⅡ,TGF-β1 and VEGF was increased. Rapamycin significantly inhibited,and there was a dose dependent,and down regulated the expression of ANGⅡ,TGF-β1,and VEGF. For the cell cycle,the S phase cells in the high glucose group were significantly higher than those in the normal group (P<0. 05),and the S phase cell proportion was decreased after rapamycin intervention (P<0. 05). Conclusion:Rapamycin can inhibit the proliferation of HBZY-1 in high glucose,promote its apoptosis and lead to G1/S arrest,and down regulate the expression of ANGⅡ,TGF-β1 and VEGF.

Angiopoietin-like proteins are a family of proteins that are closely related to lipid, glucose and energy metabolism, as well as angiogenesis. To date, eight Angptls have been discovered, namely Angptl1 to Angptl8 that play key roles in metabolic regulation and marker assisted selection. In this review, we summarized current progress on the structure, signaling pathways, upstream regulatory genes and metabolic network of Angptl1-8. Finally, in combination with our work, the status and problems of animal breeding as well as the future prospects for Angptls were discussed.

Objective To study the value of zoledronic acid combined with psychological intervention in osteoporotic vertebral compression fractures in percutaneous balloon kyphoplasty (PKP). Methods 72 patients with osteoporotic vertebral fractures underwent PKP operation from August 2013 to August 2015 were randomly divided into observation group and control group,with 36 cases,in each group. The patients in the control group were given salmon calcitonin after operation. The patients in the observation group were given zoledronic acid after operation. Both patients were given psychological care. The total effective rate of clinical treatment and the incidence of secondary osteoporotic vertebral compression fractures,Visual analogue pain scale before and after treatment (VAS), Oswestry dysfunction index questionnaire (ODI) score, bone mineral density T value changes were compared between the two groups. Results The total effective rate was 94.44% in the observation group and 77.78% in the control group (P<0.05). The recurrence fracture rate was significantly lower than that of the control group (P<0.05). After treatment, the scores of VAS and ODI in the observation group were significantly lower than those in the control group (P<0.05). The T value of bone mineral density was significantly higher than that of the control group (P<0.05). Conclusion Zoledronic acid combined with psychological intervention can effectively improve the effective rate of PKP after osteoporotic vertebral compression fractures, increase bone density and reduce the incidence of fracture, which is worthy of clinical application.

Objective To investigate the effects of normobaric hyperoxia intervention on learning and memory abilities of valproic acid(VPA) autism model rats and the morphology of pyramidal cells in hippocampus CA1 area.Methods Animal model groups of autism were obtained in male offspring of the Wistar rats that received intraperitoneal injection of 600 mg/kg VPA at the 12.5 day after pregnancy.According to the eye opening time,behavior,weaning weight and the learning and memory abilities which were evaluated by the Y electricity maze test at the 28th day after birth,40 male VPA autism model rats were randomly selected 20 only and divided into normobaric hyperoxia model group (group A,n =10),atmospheric air model group (group B,n =10).Normal control groups were obtained in male offspring of Wistar rats that received intraperitoneal injection of equivalent physiological saline at the same period pregnancy.(group C,n =10).Rats in group A were treated with oxygen for 1 h per day and lasted 1 week;group B and C were treated with normal air.The learning and memory abilities of three groups were assessed at the 35th day after birth.The immunohistochemistry methods and image analysis were used to observe the pyramidal cells of autism model rats in hippocampal CA1 region.The effect of normobaric hyperoxia therapy on pyramidal cell of autism model rats in hippocampal CA1 region were evaluated by HE staining technique.Results The trying times of group A after treatment were less than those before treatment (31.15 ± 0.99 vs 31.54 ± 0.97,t =2.739,P =0.018).The memory times were more than those before treatment (3.00± 0.58 vs 2.69 ± 0.48,t =-2.309,P =0.040).The trying times of group A after treatment were less than those in group B after treatment (P =0.016).The memory times of group A were not different from that in group B after treatment(P=0.810).The morphology of pyramidal cells in hippocampal CA1 region showed that the pyramidal cells of the autism model rats had apoptosised.The number of apoptotic cells reduced and the number of normal form cells increased after the normobaric hyperoxia intervention compared with the autism model rats.Conclusion Normobaric hyperoxia intervention can improve the learning and memory abilities of the autism model rats.The apoptosis of the pyramidal neurons in hippocampal CA1 might be reduced after the normobaric hyperoxia intervention.

Objective To investigate the effects of hyperbaric oxygen on learning and memory ability in rats with a model of VPA autism and on the pyramidal cells in the CA1 region of the hippocampus.Methods An animal model of autism was established in the offspring of Wistar rats which had received a single intraperitoneal injection of sodium valproate at the 12.5th day of pregnancy.A total of 48 male VPA autism model rats were randomly divided into the hyperbaric oxygen group,a high pressure air group,a normal pressure high oxygen group and a normal pressure air group (each group with 12 rats).A normal control group was obtained by injecting physiological saline.The autism model rats of the hyperbaric oxygen group were treated with high pressure oxygen in an animal experiment cabin which was cleaned with pure oxygen for 10 min,pressurized for 15 min,held at 2.0 atmospheres absolute (ATA) for 45 min and then had the pressure relieved over 15 min.For the high pressure air group the cabin was pressurized with air for 15 min,held at 2.0 ATA for 45 min and the pressure was relieved over 15 min.For the normal pressure,high oxygen group the cabin was cleaned for 10 min with pure oxygen,then pure oxygen was supplied for 1 hour with the cabin door open.The normal pressure air group rats were placed in the open cabin with no pressure or additional oxygen.The testing lasted 7 days for 1 hour per day.The normal control group rats were placed in ordinary cages.Learning and memory were evaluated using the Y electric maze test before and after the interventions.Any changes in the pyramidal cells in the CA1 region of the hippocampus were observed after hematoxylin and eosin (HE) staining.Results The average number of tries of the hyperbaric oxygen group after treatment was significantly less than before treatment and memory retention times were increased.The number was also less in the normobaric hyperoxia group and memory retention times again improved.The number of apoptotic cells was reduced and the number of normal form cells in the CA1 region increased after the hyperbaric oxygen intervention.Conclusions The learning and memory abilities of the autistic rats improved after the hyperbaric oxygen intervention.Pyramidal cells in the CA1 region proliferated and the number of apoptotic cell decreased.This may be the mechanism by which hyperbaric oxygen intervention treats autism.

Objective To study the formations of several ridges in peripheral artery velocity tracing. Methods The experimental models of constrainting limb and adrenaline were performed in 6 juvenile susscrota domesticas,tbe variations of the external lilac artery velocity tracing observed,and the parameters of peak systolic velocity (PSV), minimum post-systolic velocity (MPV), peak diastolic velocity(PDV) and end diastolic velocity(EDV) were obtained. Results With the increase of downstream circulation resistance, systolic waveshape inclined to acumination, MPV gradually degraded to zero and negatively increased subsequently, diastolic wave amplitude lowered, and EDV gradually decreased to zero. The stronger vasoconstriction was, the more striking the variations were. Conclusions Cardiac ejection forms systolic dominant wave, post-systolic backward ware is the result of backstreaming because of elastic recoil of downstream artery,and diastolic forward ware is the result of blood transient acceleration caused by elastic recoil of upstream artery. Systemic vascular resistance has significant effect on diastolic waveshape,and the occurrence of post-systolic backward ware implies downstream circulation resistance obviously increases.
