ObjectiveTo investigate the effects of rosiglitazone, the agent of highly selective peroxisome proliferator-activated receptor-γ agonist, on the renal injury of rats with severe acute pancreatitis. MethodsFifty-four male Wistar rats were randomly (random number) divided into three groups : sham operation group ( SO group), severe acute pancreatitis group ( SAP group ) and rosiglitazone pretreatment group (ROSI group) . Severe acute pancreatitis model was induced by retrograde infusion of 5％ sodium taurocholate into the biliopancreatic duct. Rosiglitazone (6 mg/kg) dissolved in 10％ DMSO were injected into the femoral vein 30 minutes prior to the modeling. The solution of 10％ DMSO was given to rats of SO group and SAP group. Rats were sacrificed 3, 12 and 24 h after modeling. The levels of serum amylase, serum creatinine, urea nitrogen, urinary albumin, urinary lgG and αl-microglobulin were measured and analyzed statistically. Kidney tissue samples were stained respectively with hematoxylin and eosin for histopathological evaluation.Results The levels of serum amylase, serum creatinine, urea nitrogen, urinary albumin, urinary IgG and αl-microglobulin were significantly increased (P ＜ 0. 05 )after modeling, while lesser increases were found in ROSI group 12 h and 24 h after modeling (P ＜0. 05)compared with those in SAP group. ConclusionsRenal injury can be induced by severe acute pancreatitis,while Rosiglitazone protects rats from renal injury in the setting of severe acute panereatitis.

Objective To investigate the effect of endovascular cooling on perioperative brain injury in patients undergoing intracranial aneurysm resection.Methods Sixteen Hunt-Hess Ⅱ -Ⅳ patients of both sexes aged 18-64 yr undergoing intracranial aneurysm resection were randomly divided into 2 groups(n = 8 each): mild hypothermia group(group MHT)and nonnothermia group(group NT).A CL-2295AE catheter was placed in the femoral vein after anesthesia induction to perform endovascular cooling.Bladder temperature was reduced to 34 ℃ and maintained for 24 h.The hemodynamic parameters were recorded during and after operation.Coagulantion function and electrolyte levels were determined at 24 h before operation and at 12 and 24 h after operation.The serum neuron-specific enolase(NSE)and S100B concentrations were determined at 1 d before operation and at 1,3and 7 d after operation by ELISA.Neurological function was assessed with GOS grade at 1 and 3 months after operation.Results There was no significant difference in hemodynamic parameters,electrolyte levels(Na+ ,K+ ,Ca2+)and coagulantion function(PT,APTT,Plt)between the two groups(P ＞ 0.05).The GOS grade was significantly higher,while serum NSE and S100B concentrations were significantly lower after operation in group MHT than in group NT(P ＜ 0.05).Conclusion Endovascular cooling(34℃,24 h)can reduce the brain injury safely and effectively during the perioperative period in patients undergoing intracranial aneurysm resection and improve the prognosis.

Gold nanostructures with unique optical and photo-thermal properties based on their size and shape have wide applica-tion potential in tumor diagnosis, imaging, photo-thermal therapy, and drug delivery because of surface plasmon resonance. The optical properties of gold nanomaterials allow its use for dark field imaging, optical coherence tomography, and two-photon imaging. Gold nanomaterials can also be used as carriers for a variety of fluorescent molecules and drugs, achieving multifunctional imaging, chemo-therapy, photodynamic therapy, and so on. Photon-electron and electron-electron interactions of gold nanomaterials, which are excited by near-infrared laser, will generate heat that can be used for tumor photothermal therapy. This phenomenon promotes drug release, and photoacoustic imaging. The combined application of hyperthermia and chemotherapy based on gold nanoparticles is effective in opti-mizing the efficacy of cancer treatments. Therefore, gold nanoparticles can integrate multiple functions into one single system and real-ize the integration of tumor diagnosis and therapy, which provide new insights for the on-demand therapy and personalized medicine de-velopment.
