Objective To investigate the role of endoplasmic reticulum stress ( ERS) in asbestos-induced Alveolar epithelial cell apoptosis.Methods A549 cells were treated with asbestos to observe the expression of ERS proteins and apop-tosis gene by immunofluorescence staining and western blotting.Results Under asbestos exposure, the expression of Bip, GRP94, IRE-1α, BAX and BAK are up-regulated.There is a positive correlativity of the expression of proteins to the ex-posure time of asbestos.Conclusion Endoplasmic reticulum stress takes part in asbestos-induced apoptosis.

Immune thrombocytopenia (ITP) is a common bleeding disease in children.Recent advances has indicated that such factors as decreased platelet,fear of bleeding,prognosis,therapy associated side effect and restricted activities,usually decreased quality of life of patients and their parents.This review focuses on domestic and overseas researches on health-related quality of life (HRQoL) in children with ITP,in order to attract more scholars' attention.HRQoL should be recommended as an important indicator in treatment and management of ITP.

Objective To explore the relationship among personality,job burnout and knowledge sharing behavior of the enterprise employees.Methods The 44 items big five inventory(BFI) ,knowledge sharing inventory and job burnout inventory were administrated to 635 employees online.Results ( 1 ) Agreeableness had a significant main effect on knowledge sharing ( β =0.135, P＜0.01); (2)Cynicism( β = -0.140, P＜0.01) and reduced personal accomplishment( β = -0.125, P＜0.01 ) had a significant effect on knowledge sharing behavior and its two dimensions; (3) Job burnout partially mediated the relationship between agreeableness and knowledge sharing behavior(P＜0.01).Conclusion Enterprise employees' personality had different effects on knowledge sharing behavior,and job burnout was an important mediating role in the relationship above.

Six cases of T-cell lyrnphoma associated with reactive histiocytic hyperplasia with hemophagocytosis (HHH) localized primarily to the skin and subcutaneous fat were described. Initial biopsy findings may he misinterpreted as benign panniculitis. Four of which were progressive, recurrent, even fatal (follow-up for 8-36 months). Histologically the lesions of all cases were composed of a mixture of small and medium sized atypical lymphoid cells and benign hemophagocytes infiltrated with neutrophils and eosinophils between fat cells. The mechanism and differential diagnosis of the disease were discussed.

Objective To explore the molecule mechanism of protective effects of transfecting human elafin gene recombinant plasmid to NCI-H292.Methods Constructe eukaryotic expression vector pEGFP-C1-elafin and transfectied it into NCI-H292 cells,then co-incubated with polymorphonuclear granulocyte(PMN) with stimulation by lipopolysaccharide(LPS).Afater 24 hour,Western bolt and MTT technique were respectively performed to detect expression of ZO-1 in cells and adhesion capability of cells with collagen.Results After stimulation with LPS,Western blot showed that the 220 ku onula occludens-1(ZO-1) protein in transfecting pEGFP-C1 NCI-H292 cells extracts were obviously decreased,in transfecting pEGFP-C1-elafin NCI-H292 cells extracts.And MTT technique showed that compared with transfecting pEGFP-C1-elafin cells,adhesion capability of transfecting pEGFP-C1 cells with collagen were obviously decreased.Conclusion Transfection of recombinant human elafin gene into airway epithelial cells could maintain airway epithelium and enhance the capability of airway to inflammatory injury.

Neuropathic pain and cancer pain are two difficult types of chronic pain to be controlled by currently available analgesics.Animal models can provide pivotal systems for preclinical study of pain.This article reviews some new models of chronic pain,such as those of cancer pain,central nerve pain,and the pain caused by peripheral nerve injury and disease-induced peripheral neuropathy.

Objective:To summarize the notice of informed consent about gene information detection,and to provide a reference for ethical review of informed consent in clinical research involved gene information detection.Methods:We researched domestic and foreign literatures about gene information detection involved informed consent and comprehensively analyzed them.Results:Gene information detection caused the individual,family,and social aspects of privacy issues,and the right not to know gene information detection had been widely recognized.Informed consent was adopted in informed consent,which not only was respect for personal dignity and autonomy,but also was conducive to the effective use of gene resources.It should construct reasonable procedural system in le gal protection,guarantee the voluntary and authenticity of consent,and put it into practice.Based on the establishment of the right not to know,the Chinese law should also prohibit the implementation of gene detection or provision of gene information put forward by employers and insurance companies.In addition,it is strictly prohibited to detect infant incurable disease genes.Conclusion:In the ethical review of clinical research,when the conflict arises,it is necessary to design informed consent to resolve the conflict between the individuals' rights not to know and their personal health benefits,and to establish reasonable procedures in legislation to ensure the implementation of informed consent.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS)is a powerful tool for routine identification of a variety of microorganisms,including bacteria,yeast and filamentous fungi.Fast,accurate, high-throughput and low-cost characteristics,and gradually used for filamentous fungal infection in the laboratory diagnosis. In the MALDI-TOF MS analysis of filamentous fungi,from sample preparation to obtaining accurate identification results, each step determines whether the medical technician can provide accurate results for the clinician.This review will provide a systematic overview of the applications and prospects of filamentous fungal analysis (including identification,typing,and an-tifungal susceptibility testing)from preparation of the test sample to the MALDI-TOF MS technique,as well as a review of some of its future developments.

Gastrointestinal bleeding in children is a potentially life threatening medical emergency requiring an appropriate diagnostic and therapeutic approach.The causes of hemorrhage are numerous and varies with age.The clinical presentation of gastrointestinal bleeding in children ranges from asymptomatic microcytic anemia to hypovolemic shock.Therefore,the primary focus in a child with gastrointestinal bleeding is rapid assessment,stabilization,and resuscitation followed by a diagnostic modalities.

Objective To summarize the bacterial drug susceptibility of common enterobacteriaceae in pediatric patients and the epidemic status of the extended spectrum beta‐lactamases(ESBLs) during 2013 and 2014 in our hospital in order to guide the clini‐cal application of antibacterial drugs .Methods Routine methods of isolation and culture were performed and the distribution of en‐terobacteriaceae with resistance were statistically analyzed with the software .Results A total of 530 isolates were collected in the hospital in which was 32 .08% Klebsiella pneumonia and 38 .87% Escherichia coli .The most sensitive drug of Enterobacteriaeeae was carbapenems .ESBLs positive rate in Escherichia coli and Klebsiella pneumonia were 32 .04% and 20% .The difference was sta‐tistically significant (P<0 .05) .Conclusion Escherichia coli and Klebsiella pneumonia were the common enterobacteriaceae in pedi‐atric patients .Carbapenems remained very high activity against Enterobacteriaceae .However ,the carbapenems resistance strains have been appeared that should pay attention .Antibiotic therapy should be based on the guidance of bacteriology to select sensitive drugs .
