Current anti-hepatoma agents in clinical aplication have not been proved to be satisfactory. The major obstacles are low efficacy, toxicity, and drug resistance. Identifying new drug targets and discovering new agents accordin gly with high efficacies and low toxicities have become the key part of the solu tion. Recent studies have shown that hyper-methylation of tumor suppressor gene s, interaction between hepatocyte growth factor and its receptor, vascular endothelial growth factor and its receptor, as well as cyclooxygenase-2 might be potential targets for hepatomachemotherapy. Indeed, agents acting on these targets have shown to be effective. In addition, other agents such as As 2O 3 have also shown th eir activities against hepatoma.

Objective: To investigate the role of fibroblast growth factor receptor(FGFR) 1 in endothelial to-mesenchymal transition(EndMT) and epithelial-to-mesenchymal transition(EMT), and to find out a new strategy to study the vascular endothelial function of diabetic renal fibrosis. Methods: Culture media from FRS2 knockdown HMVECs was transferred to HK-2 cells. Western blot and immunofluorescence staining were used to measure EMT markers and key moleculars of transforming growth factor(TGFβ). Results: It was found that the medium from FRS2 siRNA-transfected HMVECs reduced E-cadherin protein levels, increased EMT markers levels, and activated TGFβ signal pathway in HK-2 cells. Conclusion Endothelial FGFR1 deficiency-induced EndMT leads to EMT in neighboring cells in a manner dependent on TGFβ1 signaling. Endothelial cell FGFR1 is an important molecule for maintaining endothelial homeostasis and epithelial homeostasis, and seems to be a key target for anti-diabetic renal fibrosis.

Diarrhea is a common intestinal symptom in macaque.The corresponding intestinal lesions of macaque are mainly described at autopsy but less observed by colonoscopy.The aim of this study was to develop a colonoscopic technique and to obtain endoscopic images of the entire colon in macaques.Eight healthy adult macaques ( 5 males and 3 females) without diarrhea for 2 months, were fed Glauber’ s salt through nasogastric tubes.The colon cleanliness was well matched to the endoscopic observation of macaque colon.The procedure took 10-20 min for each animal.There was no obvious abnormality in the colon of four animals except some slight differences of mucosal structure from that of human beings.Small pieces of erosion and ulcer in the colons were observed in four macaques which presented mild diarrhea for less than 1 day, while a severe stenosis was observed in one of those four macaques.No animal died during and one week after the endoscopic procedure.Colonoscopy may safely performed in macaques.The images taken by colonoscopy may be important to establish diagnosis and treatment of colitis in macaques in time and to evaluate the efficacy of drug intervention as well.This technique is also helpful to provide qualified macaques for scientific researches.

Objective To investigate the diagnostic value of B7-H3 and carcinoembryonic antigen (CEA) on diagnosis of malignant pleural effusion (MPE).Methods We collected and analysed the expression of B7-H3 and CEA in 40 MPE cases and 22 cases of benign pleural effusion (BPE) using enzyme-linked immunosorbent assay (ELISA).Receiver operator characteristic curves (ROC) were drawn according to the expression of B7-H3 and CEA, calculated diagnosis sensitivity, specificity and the area under curve (AUC).Results The diagnosis sensitivity of B7-H3 was 62.5％, specificity 81.0％, with the AUC of 0.777;similarly, The diagnosis sensitivity of CEA was 72.5％, specificity 81.0％, with the AUC of 0.850.Higher AUC of 0.910 was gained in combination ROC, with sensitivity and specificity of 72.5％, 81.0％, respectively.Conclusion B7-H3 and CEA could be available diagnosing markers for MPE.Combined applications of B7-H3 and CEA have higher AUC.They may be widely applied in future clinical practice.

Objective To explore the role of fibroblast growth factor receptor ( FGFR ) 1 in endothelial homeostasis via an induction of microRNA let-7s, with effects on AcSDKP(N-acetyl-seryl-aspartyl-lysyl-proline) and associated mitochondrial biogenesis. Methods Blocking FGFR1 signaling pathway, Western blot and immunofluorescence staining were used to measure mitochondrial fusion ( mitofusin-2, MFN2;optic atrophy protein 1, OPA1 ) and fission ( dynamin-related protein-1, DRP1 ) proteins and mitochondrial biogenesis by MitoTraker Green. Also real-time quantitative PCR(qPCR) was performed to test microRNA let-7' expression. Results FGFR1 signaling pathway was critical for AcSDKP maintaining mitochondrial biogenesis through induction of microRNA let-7b. In endothelial cells, the AcSDKP restored the triple[TGF-β2, interleukin (IL)-1β, tumor necrosis factor (TNF)-α]-suppressed microRNA let-7b-5p expression and associated with mitochondrial biogenesis. Such effect of AcSDKP was lost in either fibroblast growth factor receptor substrate 2 (FRS2) siRNA or neutralizing FGFR1 treated-cells. Similarly, AcSDKP lost its effect on mitochondrial biogenesis in microRNA let-7b-5p inhibitor-treated-cells. In addition, microRNA let-7b-5p mimic reversed the FRS2 siRNA-suppressed mitochondrial biogenesis in endothelial cells. Conclusion These findings demonstrated that FGFR1 is critical for maintaining mitochondrial biogenesis through control of microRNA let-7b-5p in endothelial cells.

Objective To evaluate he significance of the Neutrophil-Lymphocyte Ratio(NLR)and the red blood cell(erythrocyte)distribution width(RDW)in distinguishing between simple and complex febrile seizures and evaluate the diagnostic values of NLR and RDW in febrile seizures. Methods Totally,100 patients aged between 6 months and 5 years diagnosed with febrile seizure were admitted to the emergency department of the hospital.Complete blood count obtained from the peripheral blood samples collected from the patients at admis-sion were evaluated. Results The average values of NLR for simple and complex seizure groups were 2.16 ± 1.26 and 3.62 ± 1.51 respectively.The average values of RDW for simple and complex seizure groups were 15.04 ± 1.73 and 16.89 ± 1.44,respectively.Using receiver operating characteristic curve(ROC),the sensitivity and specificity were 65.5% and 66.2%,respectively,with the area under the curve[AUC]of 0.670 when the cut-off value was 2.52 for NLR,and they were 62.1% and 59.3%,respectively,with AUC of 0.619 when the cut-off value was 16.47 for RDW. Conclusion NLR and RDW may provide clinicians with an insight into differentiation between simple and complex febrile seizures,however,we need much better diagnostic value to classify the febrile seizures

Diabetic peripheral neuropathy (DPN) is one of the chronic complications of diabetic neuropathy, and also the main cause of chronic wounds and disability. Exosomes and exosomal-microRNAs (miRNAs) are closely related to DPN and participate in the signal transduction and protein expression of the peripheral nervous system by mediating intercellular communication. However, the specific role and mechanism of EVs and exosomal-miRNAs in the occurrence and development of DPN in high-glucose environments are not fully understood. This article reviews the promotion of EVs and exosomal-miRNAs in the occurrence and development of DPN in inhibiting axon growth, promoting inflammatory response, and inducing vascular injury in a high glucose environment.

Objective: To analyze the impact of dual antiplatelet (DAPT) therapy combining with or without proton pump inhibitors (PPI) on the main outcomes after percutaneous coronary intervention (PCI). Methods: The PubMed, EMBASE and Cochrane Library were searched for relevant literature and the references obtained from these sources were retrieved manually from inception till September 2017. Inclusion and exclusion criteria were established follow the Cochrane review standard. A total of 977 literatures were included, 193 duplicates were excluded, 74 reviews, case reports, letters and systematic reviews were excluded, 667 literatures were excluded after reading the title and abstract, 34 literatures were excluded due to non-randomized control studies and unrelated outcome indicators, and 9 literatures were finally included with a total of 16 589 patients. RevMan 5.3 software was used to compare the incidence of major adverse cardiovascular events (MACE), cardiogenic death, recurrent myocardial infarction, target vessel revascularization, all-cause death, stent thrombosis, stroke, gastrointestinal bleeding and gastrointestinal events in patients with DAPT combining with or without PPI after PCI. Results: MACE was observed in 8 out of the 9 included literatures, and the results showed that MACE occurred in 561 out of 6 282 patients receiving DAPT combining with PPI therapy and in 951 out of 9 632 patients using DAPT alone (OR=1.15, 95%CI 0.88-1.51, P>0.05). Cardiogenic death was observed in 7 out of the 9 included literatures, and the results showed that cardiogenic death occurred in 172 out of 6 453 patients receiving DAPT combining with PPI treatment and in 321 out of the 9 839 patients using DAPT alone (OR=0.97, 95%CI 0.80-1.18, P>0.05). Recurrent myocardial infarction was observed in 7 out of the 9 included literatures, the results showed 416 out of 6 282 cases in DAPT combining with PPI therapy group experienced recurrent myocardial infarction and 691 out of 9 632 cases in DAPT group experienced recurrent myocardial infarction (OR=1.01, 95%CI 0.89-1.16, P>0.05). Four out of 9 literatures observed revascularization. The results showed that revascularization was performed in 64 out of 2 173 patients receiving DAPT combining with PPI therapy and in 105 out of the 2 770 patients using DAPT alone (OR=1.33, 95%CI 0.55-3.24, P>0.05). All-cause death was observed in 7 out of the 9 included literatures, and the results showed that all-cause death occurred in 172 out of the 6 453 patients in DAPT combining with PPI therapy group and in 321 out of the 9 839 patients using DAPT alone (OR=0.97, 95%CI 0.80-1.18, P>0.05). Three out of the 9 included articles observed stent thrombosis, and the results showed that stent thrombosis occurred in 99 out of 2 997 patients receiving DAPT combining with PPI therapy and in 245 out of the 6 198 patients treated with DAPT (OR=1.07, 95%CI 0.83-1.37, P>0.05). Stroke was observed in 2 out of the 9 included literatures. The results showed that stroke occurred in 5 out of 2 019 patients receiving DAPT combining with PPI therapy, and in 4 out of the 2 033 patients treated with DAPT (OR=1.00, 95%CI 0.29-3.49, P>0.05). Gastrointestinal bleeding was observed in 6 out of the 9 included literatures. The results showed that gastrointestinal bleeding occurred in 26 out of 3 517 patients receiving DAPT combined with PPI therapy, and in 93 out of the 3 506 patients treated with DAPT, gastrointestinal bleeding was significantly lower in the DAPT combining with PPI group than DAPT alone group (OR=0.27, 95%CI 0.17-0.41, P<0.01). Gastrointestinal events were reported in 6 out of the 9 included articles. Similarly, gastrointestinal events were observed in 51 out of 3 517 patients receiving DAPT combined with PPI therapy, and in 190 out of the 3 506 patients treated with DAPT alone, the incidence of gastrointestinal events in the DAPT combined with PPI group was significantly lower than DAPT alone group (OR=0.24, 95%CI 0.14-0.42, P<0.01). Conclusions The incidence of MACE, cardiogenic death, recurrent myocardial infarction, target vessel revascularization, all-cause death, stent thrombosis and stroke are not affected by DAPT combined with PPI therapy after PCI, while the incidence of gastrointestinal bleeding and gastrointestinal events could be reduced by adding PPI to DAPT in patients undergoing PCI.
