1.Preconditioning with desflurane, sevoflurane and isoflurane increase the preservation of adenosine triphosphate in anoxia-reoxygenation myocardial cells
Chinese Journal of Clinical Pharmacology and Therapeutics 1999;0(04):-
Aim To study the effects of preconditioning with desflurane, sevoflurane and isoflurane on adenosine triphosphate (ATP) in anoxia-reoxygenation myocardial cells. Methods Rat ventricular myocytes, cultured for 4~5 days, were randomly allocated to five groups: Control group, anoxia-reoxygenation group and groups preconditioned with 1.5 MAC desflurane, sevoflurane or isoflurane following anoxia-reoxygenation. The content of intracellular ATP ,the activities of lactic dehydrogenase(LDH) and creatine kinase(CK), and the cell viability were measured at the end of experiment.Results Preconditioning with 1.5 MAC desfllurane, sevoflurane or isoflurane significantly attenuated the great reduction in ATP and cell viability and the increase of LDH and CK caused by anoxia-reoxygenation. There was a positive correlationship between ATP and cell viability,and a negatiue correlationship between LDH and CK (r was 0.83, -0.87 and -0.82 respectively, P

Objective To investigate the relationships between serum concentration of RBP-4 and the parameters of inflammatory, lipid metabolism, insulin resistance in patients with T2DM. Methods 71 patients newly diagnosed with T2DM and 34 subjects with normal glucose tolerance (NGT) were enrolled in this cross-sectional study. Additionally, another subset analysis was performed. Subjects were divided into normal weight (NW) and overweight or obesity (OW/OB) group on the basis of BMI. Serum RBP-4 was measured with ELISA. Serum concentrations of hs-CRP, free fatty acids (FFA), triglyceride (TG), total cholesterol (TC) and insulin were measured in fasting status. Insulin resistance was assessed by HOMA-IR. Results Ln (HOMA-IR) and the concentrations of TG, FFA, In(hs-CRP) in T2DM were significant-ly higher than that of NGR group[1.20±0.38 vs 0.76±0.34,(2.74±2. 20)mmol/L vs (1.88±1.41),(0. 80±0. 29)mmol/L vs (0.61±0.22)retool/L,0.62±1.00 vs -0. 17±1.07] . InRBP-4 showed a positive relationship with In (HOMA-IR) ( r =0. 382, P <0. 05), but no association with TC, TG, FFA and In(hs-CRP). In the group of T2DM, InRBP-4 showed a positive relationship with FFA ( r =0. 242, P <0.05) and In (hs-CRP) ( r =0.346, P <0.01), but no association with TC, TG and In (HOMA-IR). There were no relationships between InRBP-4 and In (HOMA-IR), TC, TG, FFA and In (hs-CRP)in NW, while in OW/OB group, InRBP-4 showed a positive relationship with In (HOMA-IR) ( r =0. 290,P < 0. 05 ) and In (hs-CRP) ( r = 0. 295, P <0.05 ), but no association with TC, TG and FFA. In a mul-tiple linear regression analysis, In( hs-CRP), TC, TG, FFA or In(HOMA-IR) was not the independent de-terminant of InRBP-4 in any group. Conclusion In patients with T2DM, InRBP-4 is positively correlatedwith In (hs-CRP) and FFA, and it may be a new marker of inflammation.

Objective To explore the angioarchitectrue characteristics and appropriate treatment strategies of dural arteriovenous fistula (DAVF) in foramen magnum region.Methods The clinical data of patients with DAVF diagnosed by digital subtraction angiography (DSA) were analyzed retrospectively.Results Thirteen patients intraoperative were found fistula and complete resection,patients discharged from hospital,DSA check showed that the DAVF fistula completely disappeared,all patients symptoms were improved to different extents.Conclusions The clinical features,prognosis and treatment methods of DAVF in forament magnum region depends on its angioarchitecture,especially the lesion site and venous drainage,surgical operation can usually find the fistula and can be completely removed.

Objectives To investigate the results of liver transplantation using steatosis liver donors in order to provide a scientific basis for the use of marginal donors.Methods From 2002 to 2011,80 of 407 were steatosis liver donors.There were 69 males and 11 females.Their age ranged from 20-54 years old.Sixteen donor livers with severe fatty liver and reperfusion injury were not used.The remaining 64 livers were divided into a S1 group (mild steatosis,n=22),a S2 group (moderate steatosis,n=25),and a S3 group (severe steatosis,n=17).A S0 group was used as a control (randomly selected fat-free liver,n=80).Results The occurrence rates of delayed graft function (DGF) in the S0,S1,S2,S3 groups were 5%,9.1%,20%,29.41%,respectively.Primary nonfunctioning occurred in 2 cases of the S3 group,which represented a 11.76% of the S3 group (2/17),and 3.12% of the total 64 cases (2/64).Conclusions Although the incidence rate of DGF was higher in the steatosis liver donor groups than the S0 group,there was no correlation in the mortality rate of the S1-S3 group within one year of transplantation.Attentions should be paid to the treatment of complications after steatosis liver transplantation.By minimizing ischemia-reperfusion injury,improving microcirculation,strengthening routine therapy and reducing the amount of immunosuppression,the same results could be achieved using steatosis donor liver and normal liver for transplantation.

Acetabular is an important human joint for weight bearing. Quadrilateral plate is a crucial structure of medial acetabulum with special morphology and important function. Quadrilateral plate fractures are common fracture in acetabulum. Quadrilateral plate fracture is hard to expose and reduction because it is in the medial of acetabulum. At the same time,the bone in the quadrilateral plate is not easy to fixed for thinning bones and adjacent to the articular cavity. The operator should know well about the anatomy and choose the suitable internal fixation. After quadrilateral plate fractures, the femur head maybe displace medially even break into pelvis. That make reduction and treatment always be a challenge. With different kinds of fractures,the efficacy of treatment is not the same. This paper intend to review the relation of anatomic features,approaches, internal fixations, key point of treatment and efficacy.

Combination chemotherapy and nanoparticle drug delivery are two promising strategies in cancer treatment. The use of multiple therapeutic agents in combination provides synergistic effects among different drugs against cancer cells and suppresses drug resistance through distinct mechanisms of action.Nanocarriers can improve anti-tumor effects of drugs and reduce systemic toxicity through delivering drugs into the tumor tissue specially. Recently, many studies are aiming to encapsulate multiple agents into nanocarriers to optimize the anti-tumor effects. In the present review, the recent advances of nanoparticle platforms applied with co-delivering two or more drugs were summarized and the various combination strategies based on nanoparticles in oncology were discussed.

Objective To compare the outcome and early patency rate of revascularization treatment for patients with iliac artery occlusion or stenosis.Methods Retrospective analysis was made on 105 cases of iliac artery occlusion or stenosis from January 2009 to April 2014.49 were with iliac artery occlusion and 56 with iliac artery stenosis.Results The demographics,and comorbidities were not statistically different between the 2 groups.The occlusion group had more critical limb ischemia and the ankle-brachial index was lower than the stenosis group.The occlusion group underwent more hybrid surgery and used more covered stents in the operation.The peri-operative complication was higher in the occlusion group,but the difference was not statistically different.The ABI improved significantly for all patients after surgery.The early patency rate was similar in the 2 groups.Conclusions Revascularization treatment for patients with iliac artery occlusion and stenosis was safe and effective,with similar early patency rate and peri-operative complications between the two groups.
