The authors designed to separate, purify and determine the monosaccharide composition of the polysaccharide from Cordyceps militaris, and study its effect on reverse cholesterol transport in vivo by isotope tracing assay. Polysaccharides were separate and purify by ion exchange column Q-sepharose Fast Flow and size exclusion column Sephacryl S200HR; the molecular weight and monosaccharide composition of the polysaccharides were determined by high performance gel permeation chromatography and high performance liquid chromatography coming with pre-column derivation, respectively. Finally, three purified polysaccharides CMBW1, CMBW2 and CMYW1 were obtained, their total carbohydrate contents were 87%, 89%, 95%, respectively; their protein contents were 6.5%, 1.3%, 2.8%, respectively; their molecular weights were 772.1, 20.9, 13.2 kDa, respectively; CMBW1 was composed of mannose, glucosamine, rhamnose, glucuronic acid, glucose, galactose and arabinose with a molar ratio of 7.25: 0.17: 1.29: 0.23: 6.30: 11.08: 0.79; CMBW2 was composed of mannose, glucosamine, galactose and arabinose with a molar ratio of 2.40: 0.16: 2.92: 0.24; CMYW1 was composed of mannose, glucosamine, glucuronic acid and glucose with a molar ratio of 0.59: 0.57: 0.45: 25.61. Polysaccharide at 50 mg x kg(-1) could significantly improve the transport of 3H- cholesterol to blood and excretion from feces. All of the three purified polysaccharides CMBW1, CMBW2 and CMYW1 were heteropolysaccharide; and they could improve reverse cholesterol transport in vivo, the underlying mechanisms are being studied.

OBJECTIVETo apply single nucleotide polymorphism (SNP) microarray for delineation of small supernumerary marker chromosome (sSMC) in two newborns.

METHODChromosome karyotyping was performed on newborns who were born in Jan. 2013 and Jan. 2014 in Haidian Maternal and Child Health Hospital because of the abnormalities found in pregnancy checkups. SNP microarray analysis was carried out on 2 newborns with de novo sSMCs (one was mos 47,XY, + mar[45]/46,XY[5] and the other was mos 47, XY, + mar [30]/46, XY [20]), which could not be determined by conventional banding techniques. Genomic DNA was extracted from cord blood samples, amplified, tagged and hybridized following the manufacturer' s protocol. Data were collected and analyzed.

RESULTThere was a 78. 6 Mb duplication in chromosome 8 for Newborn A, which was associated with 8p22 duplication syndrome; and a 32. 7 Mb duplication in chromosome 13 for Newborn B, which was not yet reported definitely as pathogenic. The newborn A was identified with agenesis of the corpus callosum, obvious right eyelid drooping, the onset of low muscle tone and mental developmental lag behind their peers, while the newborn B had normal findings on physical and mental evaluation.

CONCLUSIONSNP-array can identify sSMCs of newborns at the DNA level, and can be used as an important supplement to the conventional karyotype analysis, but the pathogenicity of positive outputs need further verification.

To confirm the etiology of a dead case for a 6 year-old female Ailurus fulgens,one strain of the predominant bacteria from pathologic tissues(heart,liver,spleen,lung and other samples) of the dead Ailurus fulgens were examined and isolated.The isolate was named R1 and no other bacteria were isolated.The bacterial etiological examination(morphological characteristics,biochemical characteristics and 16S rDNA gene detection)of R1 showed that it was identifed as K.peneumoniae.Artificial infection to mice about R1 was also conducted in this study.R1 had strong pathogenicity to mice and the LD50 is 6.5 × 104 CFU/mL.Moreover,the clinical and pathological features of the dead mice were consistent with that of the Ailurus fulgens.To find effective therapeutic drugs of curing other Ailurus fulgens,antibiotic sensitivity test of R1 was conducted,and the results revealed that R1 was highly sensitive to cefotaxime et al,moderately sensitive to amikacin and resistant to penicillin.These data showed that K.peneumoniae was bacterial pathogen leading to death of the Ailurus fulgens and it had strong resistance to penicillins,macrolides and virginiamycin and it had broad drug resistance spectrum.However,R1 is sensitive to cephalosporins and aminoglycoside antibiotics.
