Objective To investigate the expression and clinical signification of tumor M2 pyruvate kinase in pa-tients with CRC, and to try to find a reliable and atraumatic method to predict the progress and pronosis in the CRC. Methods ELISA method was used to determine the serum levels of tM2-PK in 68 patients with CRC,40 pa-tients with colorectal polyps and 40 cases of normal subjects; immunohistochemistry ( IHC ) methods were respec-tively used to detect the expression of tM2-PK in tissues. Results ① The level of serum tM2-PK in patients with CRC was significantly higher than the group of patients with polyps and the normal subjects ( P<0.05 ) . The serum tM2-PK levels was closely correlated to tumor size and Duke stage.②The positive rate of tissue tM2-PK was signif-icantly higher in CRC than in colorectal polyps and normal subjects ( P<0.05 ) . Tissue tM2-PK levels was closely correlated to tumor size,Duke stage and differentiation grade. ③Serum tM2-PK levels was correlated to tissue tM2-PK levels (r=0.357,P=0.003). Conclusion Combined detection of expression of tM2-PK can provide the basis theory for the diagnosis and prognosis evaluation of CRC.

Objective: To optimize the synthesis of PEGylated puerarin (PEG-PUE) by orthogonal test with multi-index evaluation. Methods: The research has focused on the optimized interacting factors of the synthetic process of PEG-PUE by HPLC, such as ratio of PEG and PUE, catalyst DMAP dosage, and reaction time, using the purity, drug loading, and yield of PEG-PUE as evaluation indexes. Results: The optimum synthesis conditions of PEG-PUE were as follows, PEG-EDC-PUE-DMAP (1 : 1.2 : 1.2 : 0.3) and reaction time 12 h. Conclusion: The optimum synthesis condition of PEG-PUE is reasonable, as well as feasible.

Objective To explore the relationship between osteopontin (OPN),its downstream product thrombin-cleaved osteopontin (NTOPN) and radiographic changes in osteoarthritis (OA).Methods The levels of OPN and NTOPN in serum and synovial fluid were tested by enzyme-linked immuno sorbent assay (ELISA) kit in 22 OA patients and 21 health controls.The correlation between the above parameters and clinical data such as radiology changes of OA patients was analyzed.Results The serum level of OPN in the OA group was positively correlated with C reactive protein (CRP) (r =0.574,P =0.005).The serum level of OPN in the OA group was slightly lower than that in the healthy control group [(1.8 ± 0.5) μg/L vs (1.7 ± 1.1) μg/L,P ＞ 0.05].Similarly,the serum level of NTOPN in the OA group was significantly higher than that in control group [(21.1 ± 11.7) μg/L vs (14.7 ± 3.6) μg/L,P ＜ 0.05].Meanwhile,serum NTOPN level in female patients was significantly higher than that in male patients [(23.2 ± 11.80) μg/L vs (11.1 ± 4.9) μg/L,P ＜ 0.05].In synovial fluid of OA group,the level of OPN was (7.75 ± 2.33) μg/L,NTOPN was (0.91 ± 0.49) μg/L and the ratio of NTOPN/OPN was 0.12 ± 0.08.The level of OPN of synovial fluid in the OA group was positively correlated with CRP (r =0.574,P =0.005).NTOPN-to-OPN ratio of synovial fluid in the OA group was positively correlated with Kellgren-Lawrence grade (r =0.535,P =0.022).Conclusions The serum level of OPN is correlated with severity of inflammation in the OA patients.Meanwhile,NTOPN-to-OPN ratio of synovial fluid is correlated with OA severity.As a downstream bioactive product of OPN,NTOPN may play an important role in OA pathogenesis.Whether these parameters can be used as predictors of joint lesion severity and inflammatory status is worth further study.

It is now clear that both endogenous and exogenous sources of nitric oxide(NO) exert important modulatory effects on cardiac mitochondrial function.There is also growing evidence that NO can be produced within the mitochondria themselves.NO can influence respiratory activity,both through direct effects on the respiratory chain or indirectly via modulation of mitochondrial calcium accumulation.At pathological concentrations,NO causes irreversible alterations in respiratory function and also interacts with reactive oxygen species(ROS) to form reactive nitrogen species(RNS),which may further impair mitochondrial respiration and even lead to open the mitochondrial permeability transition pore and induce cell death.Diabetes,aging,myocardial ischemia,and heart failure are all associated with altered ROS generation,which can alter the delicate regulatory balance of effects of NO in the mitochondria.

Objective In this study,the authers investigate the effect of lumbar arachnoid space continuous drainage to prevent and reverse cerebral vasospasm (CVS) angiographically following experimental subarachnoid hemorrhage (SAH).Methods SAH model was achieved by cisternal magna twice injections of autolugous blood.Thirty adult mongrel dogs presented with SAH were randomly divided into five groups: early-drainage group,later-drainage group,early-puncture group,later-puncture group and control group. The lumbar puncture two groups started to puncture and exclude blood cerebral spinal fluid(CSF) 2 hours later following the second injection and on day 5 respectively,while the drainage two groups started to drain at the same time.The degrees of CVS were analyzed through cerebral angiography(%reduction of basilar artery diamiter,%RBAD). Results ①Compared with early puncture group and control group,early drainage group had less cases of CVS and the degrees of CVS were more slight which relieved within shorter period than other two groups.②Compared with later puncture group and control group,later drainage group had less cases of CVS and the period of CVS was shorter.③Compared with later drainage group,there were less cases of CVS and the degrees of CVS were more slight in early drainage group.Conclusions Lumbar subarachnoid space continuous drainage may prevent and reverse the CVS following SAH.Early lumbar subarachnoid space continuous drainage should be presented with better consequence.

Objective To identify objective methods for medical service performance evaluation,and means to improve the efficiency of medical services.Methods By means of collection of medical records from 10 tertiary hospitals in Yunnan in 2012,and Diagnosis-related groups of Beijing version(BJDRGs)as a risk-adjustment tool,medical service performance was made to such hospitals.Results The capacity,efficiency and medical safety of hospital of the hospitals were subject to a comprehensive evaluation of their medical service capabilities.In terms of discharged inpatients and total weight,hospital A were found to be the highest(77 458 cases,104 227.5 respectively),and hospital I the lowest(25 450 cases,38 162.28)among these hospitals in 2012; compared with other hospitals,DRG groups of hospitals A,b and D were found higher,while the case mix index(CMI)of hospitals e and I were higher.The expenditure index of hospital C is the lowest(0.9359,0.8514); the mortality in cases of low risk of hospitals B,c and D were the lowest,while hospital F was the highest.Conclusion DRGs as a risk adjustment tool,can significantly improve the reliability,science and continuity of medical service performance evaluation,providing reliable basic data for hospitals accreditation in Yunnan.
