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 correlation between large platelet ratio (P-LCR) and stroke in patients with atrial fibrillation. Methods 152 consecutive patients with atrial fibrillation were selected and divided into two groups according to whether accompanying stoke or not. Clinical features of patients and blood test indicator P-LCR were analyzed by Logistic regression analysis. Results In total, 152 subjects, including 47 patients with stoke and 105 patients without stoke,were included in the study. Univariate analysis showed that the difference in age, diabetes, hypertension, lipid-lowering therapy and P-LCR between two groups was statistically significant (P < 0.05). Logistic regression analysis showed that age, diabetes and P-LCR were independent risk factors of stroke in patients with atrial fibrillation. Conclusions Age, diabetes and P-LCR are independent risk factors of stroke in patients with atrial fibrillation.

BACKGROUND:Bone transplantation is the only method for the repair of bone defects. However, traditional bone transplantation has some disadvantages. Bone tissue engineering, as a new treatment strategy, can achieve the desire therapeutic outcomes. OBJECTIVE:To fabricate a new tissue-engineered scaffold for improving bone repair effectively. METHODS:Hydroxyapatites (HA) with different Ca/P (1.50/1.67) ratios were synthesized by chemical precipitation method and microwave radiation method. Composite scaffolds of palygorskite (APC)/HA/polycaprolactone (PCL)/col agen (COL), APC/calcium deficiency HA (CDHA)/PCL/COL, and APC/PCL/COL (control group) were prepared by solution perfusion-solvent evaporation and ion leaching method. The material characterization, active ingredients, hydrophilic property, and mechanical properties were evaluated by scanning electron microscope, infrared spectrometer, surface contact measuring instrument and universal mechanics, respectively. The histocompatibility of the implant with the host was assessed through animal experiments. RESULTS AND CONCLUSION:By precise control of pH range, HA with different Ca/P ratios could be synthesized. The mechanical properties, air permeability, hydrophilic property of the APC/HA/PCL/COL and APC/CDHA/PCL/COL composite materials were significantly increased compared with the APC/PCL/COL composite material (P<0.05), while the porosity, water absorption expansion rate were significantly decreased (P<0.05). Results from our animal experiments showed that no immune inflammatory reaction was observed suggesting that the composite materials hold good histocompatibility. To conclude, the APC/HA (1.50/1.67)/PCL/COL composite materials are promising bone substitutes in bone tissue repair.

OBJECTIVETo evaluate computed tomography (CT) and magnetic resonance imaging (MRI) findings in patients with autoimmune pancreatitis (AIP).

METHODSThe imaging findings of pancreas and extra-pancreas in 24 patients with AIP were retrospectively reviewed. Among them, CT scan was performed in 18 patients, MRI in 11, and bGth CT and MRI in 10.

RESULTSThe pancreas showed diffuse enlargement (25%, 6/24), focal enlargement (37. 5%, 9/24), combined enlargement (25%, 6/24) ,and no enlargement (12. 5%, 9/24). Unenhanced CT showed hypoattenuation in AIP area (n = 2) . After intravenous injection of contrast medium, 17 patients showed abnormal contrast enhancement in the affected pancreatic parenchyma, including hypoattenuation during the arterial phase (50%, 9/18) and hyper attenuation during the delayed phase (94. 4%, 17/18). Precontrast MRI showed abnormal signal intense (n =9), including hypointense on T1-weight images (T1 WI) (n = 7), hyperintense (n = 7) and hypointense (n = 2) on T2-weight images (TIWI). Enhanced MRI demonstrated abnormal contrast enhancement within lesions (n = 11), including hypoattenuation during the arterial phase (81. 8%, 9/11) and good enhancement during the delayed phase (100%, 11111). A capsule-like rim was seen around pancreas (37. 5%, 9/24), among which CT detected in 6 out of 18 patients and MRI found in 7 out of 11 patients.The main pancreatic duct lumen within lesions has no visualization (100%, 24/24) and upstream dilation of the main pancreatic duct (n = 8) , ranging from 2. 2 to 4. 5 mm(mean 3. 1 0. 47 mm) in diameter. Narrowing of the common bile duct was shown in 14 patients. Miscellaneous findings were: infiltration of extrapancreatic vein (n = 9) and artery (n = 1); mild fluid collection around pancreas (n = 2); pseudocysts (n = 3). Fourteen patients also presented one or more of the following extrapancreatic imaging findings: narrowing of the intra-hepatic bile duct or hilar duct (n = 5); thickening of gallbladder wall (n = 5); fibrosis in mesenteric (n = 2), in retroperitoneal (n = 2) and in ligamentum teres hepatis (n = 1); renal involvement (n = 3); peri-pancreatic or para-aortic lymphadenopathy (n = 10); and ulcerative colitis (n = 3).

CONCLUSIONAIP display some characteristic CT and MRI imaging features: sausage-like change of the pancreas; capsule-like rims around lesions; delayed contrast enhancement in the affected pancreatic parenchyma; segment or diffuse pancreatic duct stenosis but mild upstream dilation and extrapancreatic organs involvement. CT and MRI findings combining with serological tests and pancreas biopsy can assist physicians to make accurate and timely diagnosis.

OBJECTIVESTo investigate sexual function before and after kidney transplantation in patients with chronic nephrosis.

METHODSEighty-six male patients were divided into 3 age groups: young-age group (Group A), middle-age group(Group B) and elder-age group(Group C). Sexual function, including potency, frequency and satisfaction of intercourse before and after the sickening, and after transplantation, were recorded in each group.

RESULTSAll the patients were potent before suffering from nephrosis. The proportion of patients who were potent after catching the disease in Group A, B and C was 28.6%, 13.8% and 9.1%, respectively. Notably, the proportion of patients remaining potent after transplantation in Group A, B and C was 88.6%, 75.9% and 63.6%, respectively.

CONCLUSIONSQuality of sexual life is significantly improved after kidney transplantation. The younger the patients, the better the improvement.

Objective To explore the relationships between hyperuricemia (HUA)，serum uric acid (SUA) level and the chronic kidney disease (CKD) in adult residents of communities. Methods A cross-sectional study was conducted in Xinqiao town of Songjiang district, Shanghai and a total of 9 527 residents aged 20-75 years were selected by random cluster sampling. Logistic regression models were used to evaluate the association between SUA and CKD. Results Subjects were divided into five groups according to the gender-specific quintiles of SUA. The CKD prevalence in serum uric acid quintiles of male were 4.9%, 5.7%, 6.0%, 8.0% and 13.8% respectively，while of female were 12.8%, 12.7%, 11.9%, 13.3% and 18.2% respectively, increasing along with the increase of SUA among both sexes (all P<0.05). Compared to the serum uric acid first quintile, the multivariate-adjusted odds for CKD in male of the fourth and fifth quintiles were 2.12 (95% CI:1.32-3.39) and 3.84 (95% CI:2.45-6.02), and the multivariate-adjusted odds for CKD in female of the fifth quintile was 1.38 (95% CI:1.05-1.80). Hyperuricemia was defined by SUA>420 μmol/L(male) or >360 μmol/L(female). In the unadjusted model, HUA was significantly associated with CKD of all subjects (OR=2.03, 95% CI:1.69-2.44, P<0.001), and the association was still significant (OR=2.04, 95% CI:1.68-2.49, P<0.001) after adjustment for the potential confounders. The multivariate-adjusted odds of CKD associated with HUA was 2.89 (95% CI:2.12-3.94,) and 1.98 (95% CI:1.51-2.60) for male and female, respectively. Conclusion Hyperuricemia was independently associated with the increased prevalence of CKD among community-based population living in the Songjiang district, Shanghai.

Objective To investigate the prevalence and related factors of type 2 diabetes mellitus(T2DM) and its associated renal insufficiency in adult residents of a community in Shanghai. Methods A total of 9 257 residents aged 20-75 years old in a community of Shanghai were selected by random cluster sampling. All participants were interviewed to complete questionnaires, physical examination, examination of blood, urine and common biochemical indicators for T2DM, renal insufficiency and other related factors. Then the SPSS 19.0 software was used for analysis. Results Of the 9 257 respondents, eligible data of 8 207 subjects were enrolled in the study. The prevalence of T2DM was 12.7% (95% CI: 12.0%-13.4%), and the prevalence of its associated renal insufficiency was 15.4% (95% CI: 12.3%-18.4%), and majority of patients (65.8%) were in the early stage. Among the T2DM patients in this survey, the prevalence of renal insufficiency in obese patients was higher than that in patient with the normal body mass index. Logistic regression analysis showed that elder (OR=1.35), central obesity (OR=1.50), hyperuricemia (OR=2.51) were independent risk factors related with renal insufficiency in T2DM patients. Conclusions Renal insufficiency has become one of the important public health problems in T2DM patients. It shows a more urgent need for early prevention and control of CKD to prevent the incidence of end-stage renal disease and related complications in T2DM patients with advanced age, obesity, and hyperuricemia.

OBJECTIVETo investigate the ability of the model for end-stage liver disease (MELD) score combined with serum sodium measurements to effectively evaluate the prognosis of patients with decompensated liver cirrhosis.

METHODSA total of 212 patients with decompensated cirrhosis were retrospectively analyzed. Each patient's MELD scores, and sodium-based MELD scores (MELD-Na, MELDNa, and MESO) were calculated at three-month intervals. The area under the receiver operating characteristic (ROC) curve (AUC) was used to compare the predictive abilities of the four scores for 3-, 6- and 12-month mortality. Kaplan-Meier survival curves were created using the best cut-off values for each score identified by the ROC.

RESULTSAmong the 212 patients, 46 died within three months, 56 died within six months, and 87 died within 12 months. The MELD, MELD-Na, MELDNa and MESO scores were significantly different between patients who survived and those who died within three and 12 months (P less than 0.01). The AUCs for the four separate scores were all more than 0.8 at the 3- and 6-month time points; however, the AUCs of MELDNa (3-month: 0.846; 6-month: 0.869) and MESO (0.831; 0.850) were significantly better than those of MELD (0.812; 0.841) (P less than 0.05). At the 12-month time point, the AUCs of MELD, MELD-Na, MELDNa, and MESO were not significantly different (0.774, 0.775, 0.786, and 0.777, respectively). Survival curves showed that all the scores were able to clearly discriminate the patients who survived from those who died within 12 months (P=0.000).

CONCLUSIONThe MELD score and its sodium-based variants (MELD-Na, MELDNa, and MESO) can precisely predict mortality of patients with decompensated cirrhosis for short and intermediate periods. The MELDNa and MESO scores are superior for predicting 3- and 6-month survival.
