Objective To compare the performance of 2009 and 2010 reference standards of the United States Clinical and Laboratory Standards Institute(CLSI)in antimicrobial susceptibility for Enterobacteriaceae.Methods The breakpoints of susceptibility for ceftriaxone,ceftazidime and aztreonam in CLSI M100-S19(2009)were used to analyze results of antimicrobial susceptibility of Escherichia coli (308 isolates)and Klebsiella pneumoniae(194 isolates),as well as those revised in M100-S20(2010).Results With both the breakpoints in CLSI M100-S19(2009)and CLSI M100-S20(2010),proportions of antimicmbial resistance of ceftriaxone,ceftazidime and aztreonam for isolates of extended-spectrum β-lactamases(ESBLs)-producing E. coli were 84.2 percent vs.98.0 percent and 84.9 percent vs.98.0percent,respectively:those for isolates of ESBLs negative E. coli were 4.2 percent vs.7.7 percent and 5.6percent vs.8.4 percent,respectively;those for isolates of ESBLs positive Klebsiella spp.were 67.2 percent vs.90.2 percent and 67.2 percent vs.90.2 percent,respectively:and those for isolates of ESBLs negative Klebsiella spp.were 9.8 percent vs.10.6 percent and 10.6 percent vs.10.6 percent,respectively.Conclusions Proportions of antimicrobial resistance for ceftriaxone,ceftazidime and aztreonam with the rcference breakpeints of CLSI M100-S20(2010)increase to various extent,8.8 compared to those with the old ones in 2009.Compared with ESBLs negative isolates,ESBLs positive isolates are affected much more by the breakpeints of CLSI M100-S20(2010).Proportion of affected Klebsiella spp.by the revised breakpoints of CLSI M100-S20(2010)for ceftazidime and aztreonam is higher than that of E. coli with ESBLs positive.

Since the tumor necrosis factor-related apoptosis-inducing ligand was found as a suitable agent for anticancer therapies,study on tumor research has been attaching more importance to it.Utilized the progress on the study of TRAIL on pancreatic carcinoma aspect recent years and standed the principle in TRAIL inducing pancreatic carcinoma apoptosis,this article first simply reviewed the resistance theory of TRAIL on pancreatic carcinoma.Following the trail of identified resistance theory,carring the method of increasing TRAIL's sensibility with protein inhibition,signal regulation,ect,some new treatments have been received,which are described along with the antitumor effect of TRAIL combined with mature treatment in pancreatic carcinoma,and simply assessed at last in the article,to provide a reference on the synergistic cytotoxic effects of TRAIL combined with valid drugs on panreatic carcinoma.

The effects of SLG on the immune function of normal and immune-suppressed mice were investigated. The results showed that SLG (50mg/kg, im) could correct the suppressive effect of cyclophosphamide, dexamethasone or prednisolone on spleen and. thymus weight, serum specific antibody level and lymphocyte transformation. SLG could also improve the phagocytic activity of peritoneal macrophages and enhance peripheral blood ANAE+-lymphocyte ratio of mice. No obvious effect of SLG on the normal mice were observed except that it could increase the antibody level of normal mice. The results implicate that SLG may have some immunomodulatory effect.

Objective Sanatoriums have many complex business systems,so there is an urgent need for safe,reliable and stable operation of data centers to provide uninterrupted data services for its business systems. Methods Based on Web service heterogeneous system integration technology,data crawling robot technology,data center core technologies related to the data center,data center of sanatoriums was built. Results Sanatorim data center is the foundation on the integration platform of information,it is an effective solution to application integration and data sharing to achieve data consistency,timeliness,completeness,safety,effectiveness and accuracy. Conclusion The relative concentration of data center in the building of sanatorium is necessary in the development of sanatorium.

Embryonal tumors of central nervous system (CNS) are highly invasive malignant tumors that mainly affect infants.Even if the current active treatment strategies are given, the prognosis is still very poor.The 2016 World Health Organization(WHO) classification integrates the genetic information of diseases with histopathology, so as to make the classification and diagnosis of these tumors more accurate.In the new classification, embryonal tumors of CNS include the most common medulloblastoma, and the rare embryonal tumor with multilayered rosettes, C19MC-altered, embryonal tumor with multilayered rosettes, not otherwise specified (NOS), medulloepithelioma, CNS neuroblastoma, CNS ganglioneuroblastoma, CNS embryonal tumor, NOS, atypical teratoid rhabdoid tumor, and CNS embryonal tumor with rhabdoid features.Further study and exploration on the biological nature of these rare brain tumors will provide scientific basis for new treatment methods.

To report a case of an adult male with a huge cavernous hemangioma arising from the nasal septum, and the lesion was widely spread to hard palate, sphenoid sinus, ethmoid sinus and right maxillary sinus. After giving embolization, it was completely excised via transnasal endoscopic approach and lateral rhinotomy, histologic examination reported cavernous hemangioma. There was no recurrence at 1 year's follow-up.

Objective To discuss the effect of blood glucose monitoring during pregnancy and pregnancy outcome in patients with gestational diabetes mellitus (GDM). Methods One hundred and fifty-three GDM patients from July 2007 to July 2008 were analysed.The cases were divided into satisfactory group (74 cases)and unsatisfactory group (79 cases) based on the level of bleod glucose and compared the pregnancy outcome between the two groups. Results The incidences of pre-eclampsia, polyhydramnios, macrosomia, neonatal hypoglycemia, hyperbilirubinemia of satisfactory group were lower than those of unsatisfactory group(5.41% vs 17.72%,4.05% vs 20.25%, 12.16% vs 31.65% , 5.41% vs 20.25%,8.11% vs 30.38%). The difference is statistically significant (P <0.05). The incidence of premature rupture of membranes, premature birth, postpartum hemorrhage, fetal distress of satisfactory group were lower than those of unsatisfactory group, but there was no significant difference between the two groups. Conclusion GDM can cause great harm to maternal and child health, and satisfactory blood glucose control during pregnancy may reduce maternal and child complications.

After the concept of data curation and its application in foreign countries were described , the key points of data curation for data service in special libraries and related problems were analyzed according to the overall needs and changes of users in special libraries.

Hematopoietic chimerism is a measure of the number of donor and recipient cells in the host following hematopoietic stem cell transplantation (HSCT), and it has a good correlation with GVHD and relapse. Chimerism detection after nonmyeloablative allo-HSCT is a simple essential and effective method to predict the outcome of the disease, and can significantly improve the success rate of transplants, reduce the recurrence and then improve the quanlity of life of patients.
