Cancer cells can change metabolic pathways, including glycolysis and glutamine metabolism, and produce the raw materials needed for rapid proliferation and survival. Therefore, research on metabolic pathways of cancer cells might help find the targets of cancer therapy. In this review, we outlined the metabolic features of aerobic glycolysis, glutamine metabolism and (tricarboxylic acid) TCA cycle in cancer. We also described metabolic targets for cancer therapy and therapeutic agents for the corresponding targets in these metabolic pathways, and finally discussed some of the challenges related to tumor metabolism as a therapeutic target in cancer therapy.

Objective To study the correlation of artery stiffness with left ventricular remodeling and cardiac function in coronary heart disease (CHD) patients .Methods Four hundred and eighty patients were divided into CHD group (n=373) and non-CHD group(n=107)according to their coronary angiography .Patients in CHD group were further divided into normal left ventricular re-modeling group (n=139) and abnormal left ventricular remodeling group (n=243) .Their brachi-al-ankle pulse wave velocity (BaPWV ) was measured .The patients underwent echocardiography and 42 patients in CHD group received Doppler tissue imaging .Results The BaPWV was signifi-cantly higher in CHD group than in non-CHD group (P<0 .01) and in abnormal left ventricular remodeling group than in normal left ventricular remodeling group (1689 ± 305 cm/s vs 1508 ± 280 cm/s ,P< 0 .05) .The BaPWV was positively related with the IVST ,PWT ,RWT ,LVMI ,E/Ea and negatively related with the LVEF ,Ea ,Ea/Aa in CHD group (P<0 .05 ,P<0 .01) .Partial cor-relation analysis showed that the BaPWV was significantly related with the IVST ,PWT ,RWT , LVMI ,LVEF ,Ea ,Ea/Aa and E/Ea when the effect of hypertension ,etc ,was excluded (P<0.01) .Multivariate regression analysis demonstrated that the BaPWV was an independent factor for LVMI and LVEF .Conclusion BaPWV is an independent factor for left ventricular remodeling and cardiac function in CHD patients .

Objective To evaluate the accuracy of multi-detector spiral CT (MSCT) semiautomated volumetric measurement of right lobes and its value in living donor liver transplantation (LDLT). Methods Fifty-six donors underwent four phases MSCT. Pre-operative liver volumes of two measurements [IQQA(R)-liver semi-automated (Vs) and manual volume (Vm) measurements] in portal vein phase were compared with intra-operative measurement (Vio) by means of water displacement. Results Correlation analysis and Bland-Altman tests were used for statistical analysis.Results Pre-operative measurements of grafts resulted in a mean Vs, Vm, Vio of (818. 60 ± 161.43)cm3 , (880. 16 ± 169. 92) cm3 and (669. 84 ± 141.37) cm3 respectively. All corresponding pre-and intra-operative data were correlated significantly with each other. There was a good correlation between Vs and Vio(r= 0. 778, P＜0. 05), so did Vm and Vio(r= 0. 746, P＜0. 05). The equations of linear regression were Vio = Vs × 0. 681 + 112. 26, and Vio = Vm × 0. 620 + 123. 81 respectively. Exact 95 % CIs and the extent of concordance were 121.57-175. 95 cm3, -354. 135-56. 62 cm3 for semiautomated measurements, and 180. 09-240. 56 cm3 , - 438. 66-18. 01 cm3 for manual measurements,respectively. Conclusion Semi-automated method for the volumetric measurements of the right liver lobes in LDLT is more accurate than the manual method.

Objective To study the effect of liver transplantation using right liver lobe Ⅴ and Ⅷ segments with middle hepatic vein(MHV) and without main MHV on the regeneration of liver transplantation. Methods 25 pair of donors and receptors of liver transplantation were divided in to two groups:with M HV group (group A, n= 14) and without main MHV (group B, n=11). The volumes of Ⅴ and Ⅷ segments of liver were measured in donors presurgicaUy,half month and 3 month in receptors postsurgically, the rates of regeneration of the Ⅴ and Ⅷ segment were calculated half month and 3 months postsurgically and compared between two groups. Results In group A,the regenerate rates of the Ⅴ,Ⅷ segment were 0.360±0.043 and 0.853±0.059 half month after surgery,0.253±0.043 and 0.708±0.059 three months after surgery respectively. In group B, the regenerate rates of the Ⅴ,Ⅷ segment were 0.306±0.049 and 0.815±0.066, respectively half month after graft, 0.161±0.049 and 0.627±0.066, respectively three months after surgery. There were no statistically significant differences in regenerate rates of the Ⅴ, Ⅷ segment of graft be-tween the two groups (P= 0.685 ,P>0.05 and P= 0.738, P>0.05). Conclusion The right lobe living donor liver transplantation, maintaining the MHV or reconstruct MHV tributaries without MHV has similar effects on the regeneration of Ⅴ,Ⅷ segment of graft.

Objective To investigate the expression of aquaporin-3 (AQP3) in tongue tissues of rats with experimental severe acute pancreatitis (SAP) and regulating effects of emodin. Methods Rat models with SAP were established by injecting 5% sodium taurocholate retrogradely into gallbladder and pancreas. SD male rats were randomly divided into sham-operation group, model group, and emodin group. After model establishment, rats in the emodin group received gavage with emodin 20 mg/kg each day, while rats in the model group and sham-operation group received gavage with normal saline. The mental state, thick greasy tongue fur and mortality of rats were observed every day after model establishment, and 5 days later, protein and genetic expression of AQP3 were detected by Western blot and RT-PCR. Results Compared with the model group, the mortality and the thick greasy tongue fur significantly decreased, the protein and genetic expression of AQP3 significantly decreased in the emodin group (P<0.05). On the 5th day, 11 rats in the model group survived, and 5 rats had thick greasy tongue fur. Compared with the sham-operation group, the protein and genetic expression of AQP3 in the model group were higher (P<0.05). Conclusion Emodin can improve the severity of SAP and decrease the incidence of thick greasy tongue fur significantly by reducing the protein and genetic expression of AQP3.
