Eukaryotic elongation factor 2 kinase (eEF2K) is well known as a Ca2+/calmodulin (CaM)-dependent kinase. eEF2K catalyzes the phosphorylation of eEF2 and subsequently inactivates eEF2 by impairing its ability to bind to the ribosome, thereby negatively modulates protein synthesis. The high expression of eEF2K has been found recently in several types of malignancies. As participating in the progress of tumor, eEF2K emerges a potential target for future cancer therapy. The relationship between eEF2K and tumor, and the latest progress of eEF2K inhibitors were summarized in this article.

Objective To investigate the effect of double versus single internal thoracic artery on sterna wound healing in coronary artery bypass grafting (CABG).Methods Patients undergoing CABG were randomly divided into experimental group (double internal thoracic artery group) and control group (single internal thoracic artery group) according to the number of internal thoracic artery used in operations.Experimental group:skeletonized double internal mammary arteries were harvested in all 50 cases (37 males and 13 females).Control group:skeletonized left internal mammary artery was harvested in all 50 cases (34 males and 16 females).Sterna wound healing and post-operational complications were observed.Results The incidence of poor sterna wound healing and volume of drainage after operation in the experimental group were more than those in the control group [volume of drainage on the first day:(350.67±56.86)ml vs (240.72 ±48.35)ml;total volume of drainage:(595.65 ± 102.35) ml vs (398.85 ± 75.84) ml;poor sterna wound healing rate:20％ vs 0;P ＜ 0.05 or P ＜ 0.01].The sterna wound healing rate of high-risk patients between two groups had significant difference (8 cases vs 0 case,P ＜ 0.05).Conclusions Compared to the single internal mammary artery grafting,the double internal mammary artery grafting increased the risk of sternal wound healing.

Objective To explore the clinical and electroencephalography features of children's frontal lobe epilepsy(FLE)and improve the diagnosis and therapy.Methods Medical records were reviewed and neuropsychological evaluations of patients with FLE diagnosed from 2000 to 2006.Children were examined by 24 h EEG and imaging examinations.Their charts for family medical history,seizure,aura,simultaneous phenomenon and anti-epilepic drug therapeutic effects were reviewed.Results Seizures were clonus in 24 cases,tonic in 4 cases,adversive,atonic,vomit in 2 cases,respectively,paresthesia,cephalic,visul,sensory in 1 case,Imaging finding were in 9 of 40.All the 40 cases were bought into 1 to 6 years' follow-up.Long-term control was achieved in 35 of 40.Partial control was achieved in 3 of 40.The left 2 cases had no response to the anti-epileptic drugs.Conclusions The common features of FLE included high seizure frequency,short duration and nocturnal preponderance.There is high positive rate of active EEG in detecting epileptic discharges,and active EEG shoud be necessary.Carbamazepine is recommended to be the first choice to FLE.

Objective To quantitatively assess the regional myocardial function in the patients with heart failure by tissue Doppler imaging. Methods The apical 4 chamber, 2 chamber and long axis view of two-dimensional tissue Doppler imaging were acquired in 30 healthy individuals and 18 patients with heart failure by GE Vivid 7 commercially machine.The basal and middle segments in left and right ventricle were analyzed in tissue velocity imaging model. The following cardiac intervals and velocities were measured in each segment, including the isovolumetric contraction time(IVCT), the ejection time, the isovolumetric relaxation time(IVRT); the rapid filling time, the artrial systolic time, the peak velocity and acceleration of Sm, the peak velocity and acceleration of Em, and the peak velocity and acceleration of Am. Results Compared with control group, IVCT, IVRT and atrial contraction time were prolonged, the ejection time and rapid filling time were shorterned, peak velocity and acceleration of Sm, Em, and Am were reduced in heart failure group. Conclusions There were characteristic changes on tissue velocity imaging in the patients with heart failure which include the delay of IVCT and IVRT and reduction of velocity in Sm, Em, and Am.

AIM:To investigate the expression and the significance of VEGF-C/D in rat cornea after alkali burning as well as the role of lymphangiogenesis in the high-risk corneal transplantation rejection.
●METHODS:The model of alkali burn corneal was made. Different times corneas were taken to electron microscope for vascularization, and examined the expression of VEGF-C/D and VEGFR-3 in l, 3, 5, 7, 14, 28d. The other rat cornea after alkali burn were divided into four parts to penetrate keratoplasty, containing only blood vessels in the cornea ( group A ) , angiogenesis and lymphangiogenesis ( group B ) , lymphangiogenesis degenerating period ( group C ) , angiogenesis degenerating period ( group D ) . ln addition, there are also normal groups ( group N ) to compare the Rl values and survival time of corneal graft.
●RESULTS: Electron microscopy showed that, when the first 7d rat cornea appeared neovascularization after alkali burn, but not lymphangiogenesis. The occurrence of new blood vessels and lymphatic in 2wk. There were no obvious lymphangiogenesis in 5wk and the angiogenesis gradually subside in 8 wk. The expression of VEGF-C/D and VEGFR-3 in the corneas of rats were up-regulated in the third days after the injury, and reached its peaks at 5d. The average survival time of group N, A, B, C, D were (14.25±0.62)d, (9.35±1.02)d, (5.06±1.13)d, (8.71±0.83) d, (9. 44±1. 05)d after transplant cornea. Compared to the rest of the group, group B plant average survival time significantly shortened (P<0. 05), while compared with group B, the survival time of A, C, D groups were significantly longer (P<0. 05).
● CONCLUSION: VEGF - C/D and VEGFR - 3 are expressed significantly after corneal alkali burn. New lymphatic vessels can accelerate high - risk corneal transplantation immune rejection.

ObjectiveTo investigate the feasibility of preventing tendon adhesion by using bFGF/ vitamin C composite biodegradable membrane.MethodsSixty Newzerland rabbits were divided into experimental and control groups randomly.After the animal model was established, the tendon autografts were encapsulated with the bFGF/vitamin C composite biodegradable membrane in experimental group, while no tendon autografts encapsulation in control.Three weeks after surgery, regular HE staining and AgNO3 staining were performed to observe the fibroblast nuclei and vitamin C.The quantity of collagen fibrils was measured by Luzex-F Image Analyzer.Eight weeks after surgery, the peritendinous adhesion and the maximum tensile load were analyzed.Results At 3 weeks after surgery, the numbers of vitamin C granules, fibroblast nuclei and collagen fibrils in the experimental group were significantly more than those in the control group(t = 11.78 ,P ＜0.001) .At 8 weeks after surgery, the peritendinous adhesion in the experimental group was significantly slighter than that in the control group(Z =3.922,P ＜0.005) ,and the maximum tensile load in the experimental group was significantly higher than that in the control group (t = 8.39, P ＜ 0.001) .ConclusionbFGF/vitamin C composite biodegradable membrane can stimulate the proliferation of fibroblasts and synthesis of collagen fibrils,improve the biomechanical property of tendon autografts and prevent the tendon adhesion.
