Objective To investigate the significance of galactose galectin-3(Galectin-3)and matrix metalloproteinase-2(MMP-2)expression in gliomas patients and thire role in process of gliomas' malignancy development. Methods Immunohistochemistry was used to detect Galectin-3 and MMP-2 protein expression in 5 normal brain tissue and 40 patients with different grade gliomas. According to positive cells number of Galectin-3,MMP-2 in tumor cells under a microscope,to determine the expression,and the positive index(LI)which came from the percentage of the positive cell number out of the total cell number was to expressed the number of positive cell. Results Galectin-3 and MMP-2 protein expression in normal brain tissue were negative. In glioma tissues,Galectin-3 was mainly expressed in the cytoplasm and membrane of tumor cells. In 23 glioma tissue withⅠor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 65 ± 3. 47)% in terms of Galectin-3 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of Galectin-3 expression was 76. 47%(13 / 17), and LI value was(27. 88 ± 22. 13)% . The difference of Galectin-3 expression and LI value were significant between specimens with Ⅰ,Ⅱ grade and Ⅲ,Ⅳ significant( χ2 = 4. 101,t = 4. 105;P < 0. 05). In human gliomas,MMP-2 expression protein was mainly expressed in tumor cells and vascular basement membrane of the endothelial cell cytoplasm. In 23 glioma tissue with Ⅰor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 91 ± 4. 78)% in terms of MMP-2 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of MMP-2 expression was 88. 24%(15 / 17),and LI value was(30. 06 ± 22. 94)% . The difference of MMP-2 expression was significant between specimens with Ⅰ,Ⅱ grade or Ⅲ,Ⅳ grade( χ2 = 7. 882,t = 4. 271;P< 0. 05). The linear correlation analysis showed that there was positively correlation between Galectin-3 and MMP-2 positive cells(r = 0. 800,P < 0. 05). Conclusion Galectin-3 and MMP-2 protein expression in Ⅰ,Ⅱgrade gliomas is significantly lower than those inⅢ,Ⅳ grade glioma,and they are positively related with the progress of malignant gliomas. Galectin-3 and MMP-2 protein can be used to evaluate or judge the malignant stage of human brain glioma.

Objective To assess the relationship between pulse wave velocity(PWV) and carotid atherosclerosis by UltraFast imaging.Methods 476 cases from Medical Examination Center of Beijing Friendship Hospital were enrolled in this study.According to intima-media thickness(IMT) of carotid artery,all subjects were divided into two groups:IMT without thickening group (G0) of 283 cases and IMT thickening group (G1) of 193 cases.Through UltraFast imaging,carotid artery PWV was measured,including the PWV at the beginning of the systole(BS) and the PWV at the ending of the systole(ES).Carotid IMT and plaque situation were recorded under gray-scale ultrasound.BS and ES were compared between the two groups.Spearman rank correlation was used to analyse the correlation between IMT of carotid artery and BS,between IMT of carotid artery and ES.Two independent samples t test to compare BS,ES between the two groups.Results BS of G1 and G0 were (6.03 ± 1.33)m/s and (5.51 ± 1.13)m/s,t =-4.571,P =0.000;ES of G1 and G0 were (8.42 ± 2.13)m/s and (7.34 ± 2.02) m/s,t =5.619,P =0.000.BS and ES of G1 were larger those of G0 respectively.BS (r =0.192,P =0.000) and ES (r =0.249,P =0.000) were correlated with the IMT of carotid artery.Conclusions Ultrafast imaging technique can quickly measure the carotid artery PWV.BS and ES of carotid artery can be quick,convenient,safe,noninvasive parameters for evaluating carotid atherosclerosis.

Objective To investigate the related factors of serum carnitine deficiency in critical ill patients, and the influence of its deficiency on the length of hospital stay. Methods A prospective study was conducted. Critical ill patients with acute physiology and chronic health evaluationⅡ(APACHEⅡ)score>12 admitted to Department of Critical Care Medicine of the First Affiliated Hospital of Sun Yat-sen University from March 2013 to September 2013 were enrolled. Serum carnitine concentration and indexes of organ function were determined,and the tolerance of enteral nutrition within 5 days,the length of hospital stay,the length of intensive care unit(ICU)stay,and the hospital mortality were recorded. The relationship between serum carnitine and indexes mentioned above was analyzed. Results Thirty critically ill patients were enrolled. Serum carnitine concentration was very low in all critically ill patients,i.e. (8.92±5.05)μmol/L(normal reference value at 43.5 μmol/L)at hospital admission. Serum carnitine concentration in patients with APACHEⅡscore>23(7 cases)was significantly lower than that in those with APACHEⅡscore 12-23(23 cases,μmol/L:5.33±1.72 vs. 10.02±5.24,t=2.300,P=0.001). Serum carnitine concentration in patients with serum total bilirubin(TBil)>19μmol/L(9 cases)was significantly lower than that in those with TBil≤19μmol/L(21 cases,μmol/L:5.54±2.70 vs. 9.84±5.08,t=2.750,P=0.014). Serum carnitine concentration was negatively correlated with the APACHEⅡscore and the TBil(r=-0.387,P=0.035;r=-0.346,P=0.048). During the 5-day observation period,enteral feeding amount〔(5 134±1 173)mL〕was positively correlated with serum carnitine concentration(r=0.430,P=0.022). In 30 critical patients,the incidence of abdominal distension was 40.0%(12/30),and the serum carnitine concentration of patients with abdominal distension was lower compared with that of patients without abdominal distension(μmol/L:7.83±4.98 vs. 9.12±5.35,t=0.707,P=0.383). The incidence of diarrhea was 26.7%(8/30),and the serum carnitine concentration of diarrhea patients was lower compared with that of patients without diarrhea(μmol/L:8.27±5.78 vs. 9.73±4.78,t=0.607,P=0.576). The mean length of hospital stay was(34.72±16.66)days. The serum carnitine concentrations in patients with hospital stay≥45 days (8 cases)were lower compared with those in those<45 days(22 cases,μmol/L:5.71±3.23 vs. 9.95±5.26,t=1.627,P=0.020). No correlation was found between serum carnitine concentrations and the hospital stay(r=-0.165, P=0.385). The length of ICU stay was(18.60±10.72)days. Serum carnitine concentration in patients with the length of ICU stay>7 days(27 cases)was slightly lower than that in those with the length of ICU stay≤7 days (3 cases,μmol/L:8.44±5.00 vs. 13.24±3.65,t=1.610,P=0.119). No correlation was found between serum carnitine concentrations and the length of ICU stay(r=-0.019,P= 0.293). In-hospital mortality was 26.67%(8/30). No significant difference in serum carnitine concentrations was found between the death group and the survival group(μmol/L:12.24±6.52 vs. 7.72±3.91,t=-1.846,P=0.098). No correlation was found between serum carnitine concentrations and in-hospital mortality(r=0.340,P=0.066). Conclusions Carnitine deficiency is significant in critically ill patients,and it is correlated with disease severity and serum TBil. The total amount of lenteral feeding was lower,and hospital stay was prolonged in critically ill patients with low serum carnitine level.

Objective To analyze the associations of the interleukin-10 (IL-10) promoter-1082G/A and-819C/T single nucleotide polymorphism (SNP) and serum level of IL-10 with intracranial aneurysm (IAs). Methods The polymerase chain reaction (PCR) and DNA direct sequencing methods were used to detect IL-10 gene promoter district two SNP site,-1082G/A and-819C/T genotype frequency and allele frequency in 206 patients with IAs and 187 controls. Chi-square test was used to analyze differences between two groups. The serum level of IL-10 was analyzed by ELISA, and t-test was used to analyze significant differences between two groups. Results There were significant differences in genotypes of GG and GA+AA, as well as the alleles G and A, in-1082G/A locus between IAs group and control group (P<0.01). There were higher frequencies of genotype GA+AA and the allele A in IAs group than those in control group (P<0.01). There was higher risk of suffering IAs in patients with genotype GA+AA (OR=4.137, 95%CI:2.476-6.914) and the allele A (OR=3.368, 95%CI:2.476-4.583). There were higher frequencies of the genotype CT+TT and the allele T in-819C/T locus in IAs group than those of control group (P<0.01). There was higher risk of suffering IAs in patients with genotype CT+TT (OR=3.393, 95%CI:1.952-5.900) and the allele T (OR=3.764, 95%CI:2.730-5.192). The serum level of IL-10 was significantly lower in IAs group than that of control group (P<0.01). Conclusion The IL-10 promoter SNP influences the expression of IL-10. IL-10 promoter-1082G/A and-819C/T polymorphisms are correlated with the formation of IAs.

OBJECTIVE: To explore the genetic basis for a child featuring unexplained rapid growth and heart malformation. METHODS: Whole exome sequencing (WES)was carried out for the patient. Suspected variant was verified by Sanger sequencing and subjected to bioinformatic analysis. RESULTS: The child was found to harbor a novel de novo c.5846_5848delATA (p. N1949del) variant in exon 48 of the FBN1 gene, which was predicted to be pathogenic by Mutation Taster. The patient was ultimately diagnosed with Marfan syndrome. CONCLUSION Above finding has enriched the spectrum of genetic variants associated with Marfan syndrome. WES has provided a powerful tool for the diagnosis of rare diseases.

OBJECTIVETo analyze chromosome aberration in a child with mental retardation and abnormalities and its parents.

METHODSChromosome G banding, multiplex ligation-dependent probe amplification, fluorescence in situ hybridization and single nucleotide polymorphisms array were employed for analysis.

RESULTSKaryotype analysis revealed that the child was 46,XX and the father was 46,XY, while the mother was 46,XX, add (12)(p13). Subtelomeric region analysis with MLPA displayed that the child has reduced ACP1 gene copy number in 2p25 region and increased SLC6A12,KDM5A gene copy numbers in 12p11 region. SNP-array has fine mapped the duplication to 12p13.33-p12.3, a 15.142 Mb region, and a deletion to 2p25.3 for 3.194 Mb, which resulted in duplication of 9 genes including SLC6A12 as well as deletion of 11 genes including SNTG2, respectively. FISH analysis revealed that the child was 46,XX,ish,der(2),t(2;12)(p25;p13)mat, or partial monosomy 2p25 and partial trisomy 12p13. In addition,the mother was a carrier with cryptic balanced translocation chromosome, 46,XX,isht(2;12) (p25;p13). Mental abnormalities and retardation of the child may be attributed to heterozygous deletion of SNTG2, MYT1L genes and duplication of SLC6A12 gene.

CONCLUSIONCombined use of MLPA, FISH and SNP-array can facilitate accurate diagnosis of cryptic rearrangement at genomic level.
