The Ebola virus belongs to the Filovirus family, which causes Ebola hemorrhagic fever (mortality, 25%-90%). An outbreak of infection by the Ebola virus is sweeping across West Africa, leading to high mortality and worldwide panic. The Ebola virus has caused a serious threat to public health, so intensive scientific studies have been carried out. Several vaccines (e.g., rVSV-ZEBOV, ChAd3-ZEBOV) have been put into clinical trials and antiviral drugs (e.g., TKM-Ebola, ZMAPP) have been administered in the emergency setting to patients infected by the Ebola virus. Here, recent advances in vaccines and drugs against the Ebola virus are reviewed.

Objective To observe the role of dual-source CT (DSCT) in the diagnosis of coronary artery fistula. Methods Nine patients with coronary artery fistula were examined with dual-source CT coronary artery angiography. Then the source images were post processed using volume rendering (VR), multiple planar reformation (MPR), maximum intensity projection (MIP) and curved planar reformation (CPR), and sequential segmental analysis of the intracardiac and extracardiac anomalies was performed. Results Coronary artery fistula in all the 9 patients were accurately displayed with DSCT, including 2 with left main trunk to right ventricle fistula, 7 with left main trunk and (or) left anterior descending artery to main pulmonary trunk fistula, 5 with complex coronary-pulmonary artery fistula. Conclusion Dual-source CT coronary artery angiography is convenient, fast, non-invasive, and may be the preferable method for diagnosis of coronary artery fistula.

AIM: To investigate the effect of mfn2 on mitochondrial function in steatosis hepatocytes. METHODS: Plasmid pEGFP-mfn2 was transfected into hepatocyte strain L02 by Lipofectamine 2000 in vitro, then the steatosis model of hepatocytes was establish by oleic acid induction. RT-PCR was used to evaluate mRNA expression and Western blotting was use to detect the protein expression. ATP level was determined by firefly luciferase bioluminescent. ROS production was measured by fluorescence probe DCFH-DA. Chondrosome transmembrane potential of L02 was observed by labeling of JC-1 and FCM. RESULTS: The stable expression of ectogenesis mitofusin2 in L02 cells was confirmed by RT-PCR and Western blotting. In the model of oleic acids induced lipid formation, Mfn2 obviously inhibited the descent of chondrosome transmembrane potential and ATP level, and increased ROS production in L02 cells. CONCLUSION: Up-regulated expression of mfn2 attenuates mitochondria dysfunction caused by oleic acids induced lipid formation.

AIM: To investigate the pharmacological effects of recombined basic fibroblast growth factor (rbFGF) on retinal ganglion cells (RGCs) of rats. METHODS: Using calibrated cross-action forceps a moderate crush injury was inflicted on the nerve. After crush injury, rbFGF, saline and VB 12 were administered by retrobublar injection. Four weeks after injury , the apoptosis of RGCs was measured with flow cytometer. RESULTS: Four weeks after operation, it was shown that the rbFGF, but not saline or VB 12 injection could significantly improve the maintainance of RGCs of rats. After 800 U, 1600 U and 2400 U rbFGF injection, the injured RGCs were rescued by 24.5%, 27.3% and 28.5% respectively. Furthermore, it was also found that rbFGF injection could effectively prevent the axons from injury. The flow cytometer showed that the rate of apoptosis was reduced markedly on 7 days at rbFGF group. CONCLUSION: rbFGF can significantly promote the functional repair of injured optic nerve. [

Objective To investigate the value of glycated hemoglobin(HbA1c)and urine trace albumin (u -ALB)content in early diagnosis of type 2 diabetic nephropathy.Methods 200 patients with type 2 diabetes were selected as diabetes group,and 30 cases of healthy people as control group.According to the content of HbA1c, the diabetes patients were re -divided into low group (HbA1c <7%),the median group(7.1%≤HbA1c≤10%) and high value group (HbA1c >10.1%).The levels of HbA1c and u -ALB were detected and the correlation between them was calculated.Results The values of HbA1c (8.85 ±1.22)% and u -ALB (88.3 ±12.4)mg/L in the diabetes group were significantly higher than those of the control group (t =10.88,54.25,all P <0.05);The level of HbA1c in the high,medium and low group[(11.02 ±1.37)%,(8.45 ±2.01)%,(6.88 ±1.23)%]were consistent with the levels of the respective levels of fasting glucose[(13.22 ±2.05)mmol/L,(9.25 ±1.28)mmol/L, (6.27 ±0.63)mmol/L].HbA1c and constituting the u -ALB levels were positively correlated in the high,medium and low group(r =0.452,0.512,0.452,all P <0.05).Conclusion The combined detection of HbA1c and u -ALB levels has important value for early diagnosis of type 2 diabetic nephropathy.

OBJECTIVETo explore the effect of internal fixation with screw through femoral epiphyseal plate on growth in- hibition via an experimental study.

METHODSForty New Zealand rabbits were randomly divided into 4 groups and 10 rabbits in each group. Epiphyseal plate was injured by penetrating of screws, and the size of damage area was controlled by changing the number of threads. Group A: blank group; group B: injury area accounted for 4% of the epiphyseal plate; group C: injury area accounted for 6%; group D: injury area accounted for 8%. The internal fixation was removed after 2 weeks, and the results were observed with X-ray film for 4 groups to judge the complications such as early closure of epiphyseal.

RESULTSIn each group, there were no statistical differences in the length of the femoral neck, the diameter of femoral neck, the diameter of the femoral head, and the epiphyseal plate closure time. The growth speed of the length and diameter of the femoral neck, as well as the diameter of femoral head, were quicker on the early phase, and the speed was slowest when the epiphyseal plate was being closed.

CONCLUSIONThe injury area of epiphyseal plate under 8% is safe for its growth. Because no evidences demonstrate the growth inhibition of epiphyseal plate, the screws can be used for rabbit epiphyseal plates.

Objective To investigate the best pathway of laparoscopic surgery for choledocholithiasis. Methods According to MRCP,the cystic duct was divided into four types.The thick-straight type (n =89)and the thin-crooked type (n =65)patients randomly received the laparoscopic operations via the cystic duct or com-mon bile duct.The operation time,transit operation rate,complication rate and length of hospital stay after opera-tion were analysed.Results There were 46 cases of the thick-straight type via cystic duct,43 cases via common bile duct.The former had shorter operation time and hospital stay after operation (P <0.05),but there was no significant difference in transit operation rate and complication rate.There were 32 cases of the thin-crooked type via cystic duct and 33 cases via common bile duct and there were significant differences in the operation time, transit operation rate,complication rate and length of hospital stay after operation(P <0.05).Conclusion Ac-cording to different types,LCTBDE is suitable for the patients with thick-straight type,and LCHTD can be per-formed in thin-crooked type.Therefore,it can maximize the advantage of minimally invasive surgery.

Objective To investigate the glucolipid metabolism in lipoprotein lipase (LPL) gene knockout mice, and to explore the possible mechanisms of insulin resistance. Methods 16- and 40-week old LPL gene knockout heterozygous mice( LPL + / -) and wild type ( WT) C57 mice were selected and divided into 4 groups:16-week LPL+ / -(n=6), 16-week WT(n = 6), 40-week LPL+ / -(n = 6), and 40-week WT(n = 6) group. LPL activity of post-heparin serum was examined. Serum triglyceride( TG) and free fatty acid( FFA) were measuzed. Intraperitoneal glucose tolerance test(IPGTT) in 4 groups of mice were performed. The glucose area under the curve (AUCG) and homeostasis model assessment for insulin resistance index and β-cell function index ( HOMA-IR, HOMA-β) were calculated to evaluate insulin sensitivity and the function of islet β-cells. Serum malondialdehyde (MDA) and total antioxidant capacity ( TAOC) levels were determined by means of colorimetric method. Using dihydroethidium( DHE) fluorescent staining method, reactive oxygen species ( ROS) levels in liver and skeletal muscle were determined. Results LPL activity levels of both 16- and 40-week LPL+ / - mice were significantly lower than that in WT mice of the same age. Serum TG and FFA of 40-week old LPL+ / - mice were significantly higher than those in WT mice of the same age(P<0. 05), and they were also higher than those of 16-week old LPL+ / - mice(P<0. 05). IPGTT showed that compared with WT mice, blood glucose level in LPL+ / - mice was significantly higher than that in WT group at 30 and 120 minute(P<0. 05), and fasting insulin and HOMA-IR were increased significantly(P<0. 05). Serum MDA of 40-week old LPL+ / - mice was evidently higher than that in WT mice by the same week(P<0. 05), while TAOC level was lower than that of WT mice (P<0. 05). ROS in skeletal muscle of 16-week old LPL+ /- mice was significantly increased. Meanwhile, ROS in both liver and skeletal muscle of 40-week old LPL+ / - mice was significantly higher than that in WT mice of the same age. Conclusion As time goes by, lipid and glucose disorders of LPL+ / - mice are aggravating, and insulin resistance develops evidently. Insulin resistance in LPL+ / -mice with dyslipidemia may be related to oxidative stress.

Objective To investigate the prognostic value of preoperative neutrophil lymphocyte ratio (NLR) in patients with gastrointestinal stromal tumors (GIST).Methods The clinical-pathological data from 85 GIST cases were collected from the Second Affiliated Hospital of Wenzhou Medical University and retrospectively analyzed from June 2009 to December 2013.According to the exclusion criteria,79 cases were enrolled.Preoperative neutrophil and lymphocyte count was collected and NLR was calculated.According to the receiver operating characteristic (ROC) curve of NLR,GIST patients were divided into low NLR group (NLR ＜ 2.30) and high NLR group (NLR ≥ 2.30).Clinic-pathological features and five year disease free survival (DFS) were compared between the two groups.Results There was a statistical significant difference in tumor size and tumor risk between high NLR group and low NLR group (respectively,x2 =9.517,12.411,all P ＜ 0.05).Univariate analysis showed that the five year disease free survival rate of low NLR and high NLR group were 78％ and 32％ (x2 =18.749,P =0.000).By multivariate analysis a high NLR was identified as an independent risk factor of poorer prognosis for patients with GISTs (RR:3.516,95％CI:1.453-8.506,P=0.005).Conclusion A high preoperative NLR is an independent risk factor for the prognosis of GISTs.
