The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

AIMThe situation of four Chinese core journals of physiology was summarized. The article also analyzed the deficiency of the periodical in order to provide better service for readers.

METHODSLiterature metrology method was used to analyze the published papers and cited papers carried in four Chinese core journals of physiology.

RESULTSThe quantity of published papers in Chinese journal of Applied Physiology was higher than that in Acta Physiologica Sinica and Progress in Physiological Sciences but was lower than that in Chinese Journal of Pathophysiology. In 2006, the funding ratio was 61.6%, but was lower than the others'. The impact factor assumed the increasing tendency, but was still lower than the others'. The paper's number and total frequency in periodical which was quoted, was as much as Acta Physiologica Sinica and Progress in Physiological Sciences, but was lower than those in Chinese Journal of Pathophysiology. The rate of high frequency paper quoted was 50%, was higher than the others'.

CONCLUSIONThe Chinese Journal of Applied Physiology has obtained some achievement since publication, but we also find the distance of funding ratio and impact factor compared with other congeneric journals. In summary, we shall try our best to make progress.

Objective To explore the effect of different proportions of mixed blood exchange transfusion on blood circulation in neonates with hemolytic disease.Methods Thirty-one newborn infants with hemolytic disease were treated by peripheral arteriovenous synchronization of exchange transfusion with different proportions mixed blood.AB type plasma was mixed with O type red blood cell(RBC) washing.The proportion for the treatment group was 1:1(the O type RBCs 2 U:the AB type plasma 200 mL),by exchange transfusion of haplotypes,in accordance with 80?mL/kg;the proportion for control group was 2:1(the O type RBC 4 U:the AB type plasma 200 mL),by exchange transfusion of double in accordance with 150-180 mL/kg.The indicators were detected,such as the exchange rate of neonatal serum bilirubin,RBC,hemoglobin(Hb),hematocrit(HCT),and the exchange transfusion quantity and days of hospitalization before and after the exchange transfusion were analyzed.Results The exchange rate of serum bilirubin of treatment group and control group was (44.92?3.99)% and (45.69?5.06)%,respectively,there was no significant difference between 2 groups(P=0.639),there was no significant difference of hospitalization days[(8.13?1.13) d vs(8.19?0.91) d]between 2 groups(P=0.884).After exchange transfusion in treatment group,the average level of the RBC,Hb and HCT were increased(P

OBJECTIVETo study the cleavage activity of specific deoxyribozyme to hepatitis C virus in vitro.

METHODSThree deoxyribozymes were designed to cleave at sites 157, 168, 173 in HCV 5'-noncoding region with the active region of 5'-GGCTAGCTACAACGA-3' respectively. Plasmid pCMV/T7-NCRC -Delta Luc was completely linearized with restriction endonuclease Xba I. HCV RNA5'-NCRC was transcribed in vitro from the linearized products and radiolabelled with [alpha-32P] UTP. Under the conditions of 37 degrees C, pH7.5, Mg2+ 10 mmol/L, the three deoxyribozymes were mixed with substrate RNA individually for 120 minutes and then the reactions were terminated. The cleavaged products were separated with 8% denaturated polyacrylamide gel electrophoresis and displayed by autoradiography. DRz3 was mixed with the substrate RNA at different Mg2+ concentrations. The cleavage efficiency was analyzed with a gel document action analyzing systems.

RESULTSUnder the adopted conditions the three deoxyribozymes efficiently cleaved to the target RNA in vitro and the cleavage activity of DRz3 was increased with the increase of Mg2+ concentration.

CONCLUSIONThe designed deoxyribozymes can cleave 5'-NCR mRNA of HCV efficiently in vitro and it is dose-respondent to Mg2+ concentration.

Objective To observe the incidence and explore the potential factors of nonresponse to cardiac resynchronization therapy (CRT) in patients with severe chronic congestive heart failure. Method CRT was performed in 119 patients with NYHA function class Ⅲ - Ⅳ and left ventricular ejection fraction ≤35% [96 men and 23 women, age (60.5 ± 11.3 ) years ]. Results Seven patients died for different reasons between 1 - 6 months post CRT and clinical and echocardiographic (Echo) data at 6 months post CRT were analyzed from the remaining 112 patients. The incidence of nonresponse to CRT was 28.57%.Compared to the response group, complete right bundle branch block, longer course of congestive heart failure, higher pulmonary systolic pressure and serum creatinine level and non-optimal target vessels positioning of the left venticle lead( the great cardiac vein and the middle cardiac vein)were the independent predictors for nonresponse after CRT( all P ＜ 0.05). Compared with nonresponse group, the dosages of digoxin and diuretics used for heart failure were significantly reduced in response group ( P ＜ 0.01 ).Conclusions The incidence of nonresponse after CRT was 28.57% in this patient cohort Higher pulmonary systolic pressure and serum creatinine level and non-optimal target vessels positioning of the left venticle lead ( the great cardiac vein and the middle cardiac vein) were the independent predictors for nonresponse after CRT.
