As one of the most sensitive cells of endoplasmic retieulum stress (ERS), pancreatic β-cells have an a-bundance of endoplasmic reticulum. Fatty acids cause apoptosis of β-cells and might contribute to β-cell loss in type 2 diabetes mellitus via the induction of ERS. Glucose is an amplifier of the ERS response to fatty acid, leading to increased β-cell apoptosis. ERS response mediates glucolipotoxicity-induced β-cell apoptosis.

Objective To expore the difference between magnetic resonance image ( MRI) expression of spinal tuberculosis and brku-cellare spondylitis. Methods Retrospectively analyzed the clinical data of 10 patients with tuberculous spondylitis and 12 patients with bru-cellar spondylitis from Jan. 2012 to Oct. 2013. All the patients were scanned by MRI, and the expression difference of MRI were compared. Results The vertebral body of spinal tuberculosis was destroyed severely, and it often accompanied by the kyphosis and multiple-level para-vertebral abscess, and even adjacent organs tuberculosis. The vertebral body of brucellar spondylitis was destroyed lightly,and the abscess is often limited. Conclusion We can distinguish spinal tuberculosis and brucellar spondylitis by the typical difference of the expression of MRI.

Objective To discuss the risk factors and outcome of abnormal lung function in adult congenital heart disease .Meth‐ods 327 patients with adult congenital heart disease undergoinglung function testing between January ,2009 to December ,2011 in our hospital were enrolled .Accorded to the severity of lung dysfunction based on predicted values of forced vital capacity (FVC) ,pa‐tients were divided into 3 groups :group A(normal lung function ,predicted FVC >70% ) ,group B(mildly impaired lung function , predicted FVC 60% -70% ) ,group C(moderately to severely impaired lung function ,predicted FVC <60% ) ,all the patients were followed‐up to January in 2013 ,the baseline characteristics and outcome were recorded ,the associate factors of moderately to se‐verely impaired lung function in adult congenital heart disease were analyzed through Logistic regression analysis ,the risk factors of death in adult congenital heart disease were analyzed through Cox regression analysis ,and Kaplan‐Meier curve compared survival rate of patients in the 3 groups .Results Lung function was abnormal in 167 patients(51 .1% ) with adult congenital heart disease , in which moderately to severely impaired were 96 patients(29 .4% ) .BMI ,smoke and enlarged cardiothoracic ratio were independent associate factors of moderately to severely impaired lung function in adult congenital heart disease (P<0 .05) .NYHA Ⅲ - Ⅳ and moderate to severe impairment of lung function were independent predictors of death in adult congenital heart disease .There were significant difference of the survival rate between group A and group C ,group B and group C(P<0 .05) ,but it was not significantly different between group A and group B(P>0 .05) .Conclusion Lung function impairment is common in patients with adult congen‐ital heart disease ,and moderate to severe impairment of lung function seriously impact the outcome of the patients .

Aim To investigate the specific binding of folate conjugated PGA to FR-positive tumor cells.Method Folate-PGA and PGA were radiolabeled with 125I by the Iodogen method to examine the binding of PGA to FR positive HeLa cells and SKOV3 cells, or FR negative A549 cells. Results 125I-folate-PGA showed specific bound to HeLa cells and SKOV3 cells; Scatchard analysis of the data estimated the Kd of binding to be 0.11 nmol?L-1 and 0.25 nmol?L-1 respectively. 125I-folate-PGA showed virtually little specific binding to A549 cells which lack folate receptors. Conclusions folate-PGA displayed high affinity and good targeting activities for FR-positive tumor cells and the data warranted further studies for enzyme prodrug therapy.

As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

In this study, we explored the mechanism of Huganning tablet (HGNP) in the treatment of nonalcoholic fatty liver disease (NAFLD) based on network pharmacology and computer-aided drug design. Firstly, the potential ingredients and targets of HGNP were identified from TCMSP database, Swiss Target Prediction database, Chinese pharmacopoeia (2015) and literatures, and then the targets of HGNP intersected with NAFLD disease targets that obtained in GeneCards database to acquired potential targets. The bioconductor bioinformatics package of R software was used for gene ontology (GO) enrichment and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. The network of “potential ingredient-key target-pathway” was formed in Cytoscape software to study the interactions between potential ingredients of HGNP, key targets, pathways and NAFLD. Based on the results of network pharmacology, the molecular docking analysis of the key targets and potential active ingredients in HGNP tablets with top degree in the network was conducted using Discovery Studio 2020 software, followed by molecular dynamics simulations, binding free energy calculation, drug-likeness properties analysis and ADMET (absorption, distribution, metabolism, excretion and toxicity) properties prediction.

OBJECTIVETo study the related risk factors for surgical site infection following Pilon fracture surgery. METH ODS: The data of 561 patients with Pilon fractures treated with open reduction plate osteosynthesis at our institution's trauma centre were collected from January 2006 to December 2012. All the patients were divided into two groups: infection group and non-infection group. In the infection group, there were 23 males and 10 females, ranging in age from 21 to 69 years old, with an average of (45.50±4.40) years old. In the non-infection group, there were 296 males and 232 females, ranging in age from 16 to 76 years old, with an average of (43.50±7.19) years old. The possible risk factors such as age, gender, smoking, diabetes, alcohol abuse, open fractures, compartment syndrome and operative time were studied. The multivariate Logistic regression model was used to analyze the risk, factors.
RESULTSThe infection rate of surgical site after Pilon fracture surgery was 5.88%. There were significant statistical differences between infection group and non-infection group in operative time, open fractures and compartment syndrome. However, multivariate Logistic regression analysis revealed that only operative time was significantly associated with surgical site infection (P=0.005, OR=44.92).
CONCLUSIONOperation time is an independent predictor for post-operative surgical site infection of Pilon fracture treated with open reduction plate osteosynthesis. Though open fracture and compartment syndrome could increase the surgical site infection rate, they could not not be considered as independent predictors.
