C-reactive protein(CRP)is the most sensitive indicator of acute phase proteins.A growing body of evidence suggests that atherosclerosis,as a main cause of cerebral infarction,is a chronic inflammtory process.The present studies have found that the CRP levels and genetic polymorphisms are associated with atherosclerosis and cerebral infarction.As compared with coronary artery disease,the association between high-sensitive CRP and ischemic stroke is more closely.This article reviews the advaces in research on the biological characteristics of CRP,the factors influencing CRP levels,the CRP levels and the correlation between genetic polymorphisms and cerebral infarction.

Vascular endothelial growth factor is a vascular endothelial cell-specific mitogen.It is the most important angiogenic factor.VEGF expresses highly after cerebral infarction.It plays importmt roles in angiogenesis and neuroprotection.At the same time,its overexpression will also increase vascular permeability;thereby it may aggravate brain edema.This article reviews the advances in research on VEGF and its receptors and cerebral infarction.

Objective To investigate the clinical and MR features of fungal encephalopyosis and fungal granuloma.Methods The clinical and MR data of 10 cases with fungal encephalopyosis and fungal granuloma confirmed by surgical pathology or clinical serum were analyzed retrospectively.Then we analyzed the clinical conditions,MR signals,lesion enhancement,DWI and MRS performance characteristics of the 10 cases.Results Six cases were fungal encephalopyosis,among which 2 cases occurred in the sella turcica after surgery which located in and above the sella turcica.2 cases occurred in the frontal lobe after frontal surgery and 1 case of them was multiple encephalopyosis.2 cases of encephalopyosis without operation history were located in the left frontal lobe and right cerebellum respectively.The abscess walls of these cases were thin and showed high tension.Furthermore,it had annular significant signal enhancement and high signal in DWI scan.One case of huge fungal granuloma located in the frontal lobe and into the sinuses which showed uneven signal enhancement. The Cho level was significantly increased.Three cases of cryptococcal granuloma showed multiple lesions located in the bilateral basal ganglia region and 2 out of them accompanied with cephalomeningitis.Conclusion The MR performance of fungal encephalopyosis was quite similar with bacterial brain abscesses,which makes the differential diagnosis difficult.The brain fungal granuloma MRS may display a significant increase of Cho level which might be related with gliosis.It shows certain characteristics of brain MR performance of cryptococcal granuloma which are multiple lesions,preferential distribution of basal ganglia region and accompanying cephalomeningitis.

Objective To investigate the antibiotic resistance and resistance genes of carbapenem-resistant Enterobacteriaceaes (CRE) isolated from 5 hospitals in Northeast China.Methods This study collected 85 CRE isolates during January 2013 to June 2015 from five hospitals in Northeast China.Drug sensitivities of 14 antimicrobial agents were determined by the broth microdilution method.The phenotypes of carbapenemases were screened by modified Hodge test and EDTA test respectively.The genotypes of carbapenemases and other extended spectrum β-lactamases (ESBL) were detected by PCR gene amplification and DNA sequencing method.Using the PCR result as gold standard, the performances of other two carbapenemase detection methods were evaluated.Results Among the 85 CRE strains collected in this study, Klebsiella pneumoniae was the most frequently isolated species (61/85,71.8%).The results of antimicrobial agent sensitivity showed that the 85 CRE strains had resistance rate of cephalosporin and β-lactams/enzyme inhibitor (piperacillin-tazobactam) over 80.0%.The resistance rate of carbapenem was high, with ertapenem 100.0% (85/85), meropenem 65.9% (56/85), imipenem 71.8% (61/85).There were 36 isolates resistant to both meropenem and imipenem.For fluoroquinolones, the resistance rates of levofloxacin and ciprofloxacin were 72.9% (62/85) and 65.9% (56/85), respectively.The resistance rate to fosfomycin and amikacin were 65.0% (55/85) and 54.1% (46/85), respectively.The resistance rate of colistin (21.2%, 18/85) and tigecycline (20.5%, 17/85) were low.Forty-nine strains were modified Hodge test positive and 12 strains were EDTA test positive.By PCR gene amplification and DNA sequencing method, 64 strains carried carbapenemase-encoding genes, of which KPC-2 was the main type (53/85, 62.4%), followed by IMP-4 (10/85, 11.8%), NDM-5 (7/85, 8.2%) and NDM-6 (1/85, 1.2%).At the same time, 85 CRE isolates had the ESBL gene detection and 47 isolates were CTX-M type ESBLs (47/85, 55.3%), with no TEM or SHV type.Conclusions Klebsiella pneumoniae is the majority of CRE strains from 5 large hospitals in Northeastern China.The CRE strains are resistant to most of antimicrobials.Most carbapenemases-producing isolates have the KPC-2 type.Nearly half of the carbapenemase-producing strains also carry ESBL genes, which makes the resistance mechanisms more complicated.
