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.

Against the backdrop of ongoing healthcare system reform and escalating competitions among hospitals in China,more and more specialists and scholars on hospital administration begin to focus their studies on the theories and practice of hospital flows.Methodology frequently called into play in such study include out-patient flow refom,progressive flow improvement,and attention to management and service.Discussed in this paper are the advantages and disadvantages of these three methods as a reference for an appropriate choice by hospitals at large.

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.

Objective To explore the application of steatosis liver donor (SLD) in piggyback liver transplantation (PBLT). Methods Sixty-four cases of SLD were subjected to PBLT and classified into light steatosis liver (S1,22 cases),moderate steatosis liver (S2,25 cases),and severe steatosis liver (S3,17 cases) groups.Eighty cases of non fatty liver selected randomly in the same period served as controls. The liver and renal function at the day of surgery,postoperative liver function recovery,complications one month after surgery,and the death of recipients were recorded.Results There was no significant difference in the liver and renal function between steatosis liver groups and control group at the day of surgery (P＞0.05). At 21st day after surgery,the liver function of 95％ recipients in control group returned to the normal level,and the liver function recovery rate in S1,S2 and S3 groups was 90.9％,80.0％,and 70.6％ respectively.Graft primary nonfunction occurred in 2 cases (11.8％) of S3 group. The incidence of complications such as bleeding,infection,hepatic artery thrombosis,ascites,sepsis in S1,S2 and S3 groups was higher than in control group (P＜0.05).One year after operation,there were two deaths in control group,one in S1 group,one in S2 group,and 5 in S3 group,respectively.Conclusion SLD can be used for transplantation,but for the transplantation with severe steatosis liver,it should be carried out carefully.

Objective To observe the clinical effect of moxibustion on body sub-health fatigue state.Methods 120 cases of body sub-health patients were randomly divided into A,B,C three groups,with 40 cases in each group.Group A was treated with moxibustion,group B was treated with acupuncture therapy,and group C (control group) did not receive any measure of treatments.Fatigue scale (FS) was adopted to the three groups respectively for measuring physical fatigue score,mental fatigue score and total fatigue score before and after the treatment.Treatment efficacy was evaluated and analyzed after three weeks of continuous treatment.Results The total score of fatigue scale was 6.10 ± 2.47、6.82± 2.36、and 10.10±2.66 respectively in group A,group B and group C.Compared with group C,the difference in group A and group B was statistically significant (P＜0.01).Compared with group B,the difference in group A was not statistically significant (P＞0.05) ; The Physical fatigue points of group A,B,C was 2.46± 2.06、3.60 ± 2.24 and 5.03 ± 2.66 respectively.Compared with C group,the difference in group A and group B was statistically significant (P＜0.01).Compared with group B,the difference in group A was statistically significant (P＜0.05).Conclusions Moxibustion and acupuncture can effectively improve patients total body sub-health state of fatigue.Moxibustion treatment showed better effects in alleviating physical fatigue,

Tumor cells can metabolize glucose through glycolysis to intermediates for biomacromolecule synthesis by inhibiting the activity of the pyruvate dehydrogenase complex (PDC) in mitochondria. In this process, pyruvate dehydrogenase kinases (PDKs) play a key role. The inhibition of the activity of PDKs can effectively block this metabolic pathway, activate mitochondrial oxidative metabolism, and induce tumor cell apoptosis. PDK inhibitors have become a research hotspot in medicinal chemistry, and novel structures targeting classical binding sites have been synthesized. In this paper, recent research progress on PDK inhibitors is reviewed to provide information on these latest entities and to explore their clinical applicability.

Objective To investigate the correlation between left ventricular remodeling and systolic function by mid-wall fractional shortening(mFS).Methods 51 cases of hypertension and 47 cases of healthy volunteers were enrolled and systolic parameters were measured as ejection fraction(EF), fractional shortening(FS) and mFS. Acorrding to left ventricular remodeling parameteres inclulding LVMI and RWT, hypertension group was divided into four subgroups. The correlation among these parameters were analyzed.Results Thicker left ventricular wall and lower mFS in patient with hypertension compaired with those in controll (P<0.05). There were negative correlation between mFS and RWTr=-0.42, P<0.05) and positive correlation between mFS and LVMI r=-0.67, P<0.01).Conclusion mFS is a valuable parameter compared with traditional parameteres such as EF and FS. There is a linear association between parameteres of ventricular remodeling and systolic function assessed by mFS in early stage of hypertension.
