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.

Currently we are still unclear in the aspect of etiology and mechanisms,and lack of medical advice based on evidence-based medicine on postural tachycardia syndrome,inappropriate sinus tachycardia and vasovagal syncope.It also prompts clinical research direction of the three special arrhythmia in future.Based on this,it is very necessary to interpret the management consensus of these three types of arrhythmia.

Objective To summarize the experience of humane care on our voluntary blood donors.Methods From March 1,2017 to March 31,2017,281 blood donors were enrolled,called the intervened group,from the fixed blood donation street-spot to investigate their satisfaction and their willingness to donate blood again or not.Meanwhile,168 donors who were not intervened were also observed,called the control group.Results In the intervention group,182 were former blood donors,and 64.5％ of the respondents believed that the staff was more trustworthy than before.And 78.2％ of the respondents expressed that the communication ability with blood donors was better than before.The incidence of adverse effect of blood donation in the 281 donors was only 0.71％,and all of them were willing to donate again,which was better than the control group.Conclusion Humanistic care during voluntary blood donation is beneficial to improve the quality of service,the satisfaction of blood donation,and help retaining the blood donors.

Objective:To study the influence of Rhizoma Corydalis before and after vinegar processing on the microelement content in the eye tissues of rats to verify the vinegar processing leading the herb to liver meridian. Methods: The rats were divided into the crude Corydalis group, vinegar processing group and negative group. The content of microelement Cu, Zn and Mn in rat ocular tissues was determined and compared after the administration. Results:Corydalis could significantly increase the content of Cu and Zn in fun-dus blood and that of Zn and Mn in the eyeball vitreous, and Rhizoma Corydalis after vinegar processing showed more obvious effect. Conclusion:Rhizoma Corydalis with vinegar processing can improve the distribution of microelements in eye tissues, and because liver opens at eyes, the results provide evidence for Corydalis after vinegar processing leading to liver meridian.

Objective To investigate the level of depression on interference suppression function in patients with coronary heart disease (CHD).Methods 15 CHD patients with major depression,21 CHD patients with mild depression and 24 CHD patients without depressive symptoms in the Affiliated Hospital of Weifang Medical University from May 2013 to March 2015 were selected to complete the Emotional Stroop task and record their accuracy and reaction time according to the Self-Rating Depression Scale (SDS) and Classification and Diagnostic Criteria of Mental Disorders in China-Third Edition(CCMD-3).Results ① The reaction time was longer (F(2,57) =71.97,P＜0.01)and the accuracy was lower (F(2,57)=8.78,P=0.04) in CHD with major depression group and CHD with mild depression group compared with CHD group.② The reaction time of negative words ((872.77±348.47) ms,(796.53±200.92)ms) was longer than positive words ((809.22±343.45)ms,(740.85±177.82)ms) in CHD with major depression group and CHD with mild depression group.③ The interference effect of negative words was bigger in CHD with major depression group and CHD with mild depression group ((35.48±181.97)ms,(7.16±200.06)ms) compared with CHD group ((-19.86± 177.82)ms).Conclusion Both CHD patients with major depression and CHD patients with mild depression have deficits in interference inhibition for negative information,which suggests that CHD with depressive individuals have impaired cognitive control function.

Objective To explore the feasibility of evaluating cardiac structure, coronary artery,pulmonary artery and cardiac function in one single scan by 320-row CT ECG-gated double phase cardiac function scan mode. MethodsForty patients underwent the 320-detector row CT double phase cardiovascular angiography. The pulmonary phase and aortic phase were reconstructed in order to evaluate the pulmonary and coronary artery. MPR reconstructions of both pulmonary and aortic phase were used to analyze the function of the two ventricles. And the results of the cardiac function were compared with those of transthoracic echocardiography. Thirty-five cases could be analyzed and diagnosed, while the other 5 cases had to be given up because of the poor imaging quality. The mean heart rate was (71.2 ± 11.2) beat per min (bpm). No arrhythmia case included. Results ( 1 ) Pulmonary embolism were diagnosed in 11 cases,coronary artery disease (CAD) were found in 5 cases, while post-stent implantation were observed in 7 cases. Six cases of congenital heart disease were diagnosed with 3 ASD and 3 primary pulmonary hypertension. Another one was diagnosed with left atrial myxoma, and 5 cases were pulmonary embolism associated with CAD. All of above cases were verified by final clinical diagnosis. (2) The heart function parameters including LVEDd , RVEDd, LVESd, RVESd and LVEF were (36.7 ±3.3), (43.3 ± 3.4) mm,(31.6±5.1), (41.3 ±5.1) mm and (47.1 ±15.1) for CT, while those were (40.3 ±3.1), (47.3 ±4.2) mm,(37.3 ±5.6), (45.3 ±3.3) mm,and (46.0 ± 14.8) for ultrasound, respectively. The CT results were correlated with the ultrasound ( n = 35, r = 0.886-0.988, P ＜ 0.01 ). (3) The average radiation exposure was ( 5.4 ± 0.5 ) mSv. Conclusions 320-row CT ECG-gated double phase cardiac function scan mode is feasible for the "one-stop-shop" examination of the cardiovascular disease. This noninvasive method is recommended for the diagnosis, differential diagnosis, treatment and prognosis of cardiovascular disease.
