Objective By detecting the mutations spectrum of phenylalanine hydroxylase(PAH)gene in phe-nylketonuria(PKU)patients and their parents. The researchers analyzed the gene mutation features and high - frequency mutations and determined the relationship between the genotype and the phenotype,which would provide a theoretical basis for the early diagnosis and genetic consultation of PKU children in the region. Methods In this study,13 exons and their flanking introns of the PAH gene in 32 PKU patients and their parents from Wuxi and Suqian in Jiangsu province were sequenced by using the next - generation sequencing(NGS)technology. Results Sixty - one mutant sites and 32 mutant genes were detected in 32 PKU patients,and the mutation detection rate was 95. 31%(61 / 64 cases). The variants at c. 721C ﹥ T,c. 1068C ﹥ A,c. 611A ﹥ G,c. 1197A ﹥ T,c. 728G ﹥ A,c. 331C ﹥ T and c. 442 -1G ﹥ A were common mutations in the region with mutation frequency over 5% . What's more,4 novel variants of c. 699C ﹥ G,c. 265C ﹥ T,c. 722G ﹥ A and c. 1194A ﹥ G were found. Of those,c. 699C ﹥ G was not recorded in the PAH variant database and HGMD database and. c. 265C ﹥ T,c. 722G ﹥ A,and c. 1194A ﹥ G were first reported in the Chi-nese population. Genotype - accurate biochemical phenotype correlation by using the Guldberg AV system revealed con-sistency rate of 38. 0%(8 / 21 cases),which the consistency rate between accurate biochemical phenotype and predic-tive phenotype of moderate to severe genotype was 92. 3%(12 / 13 cases),and mild genotype was 50. 0%(4 / 8 cases). Conclusions The PAH gene variants of PKU patients in Jiangsu province are distributed mainly in exons 7,of which the highest frequency gene mutation is c. 721 c ﹥ T. Moreover,one novel variant c. 699C ﹥ G was reported for the first time. The PKU children inherit the PAH mutation gene mainly from both parents. There are definite correlation between the genotypes and phenotypes.

OBJECTIVETo investigate the MUT gene mutations in patients with methylmalonic acidemia (MMA), and analyze the genotype-phenotype correlation in patients with methylmalonyl-CoA mutase deficiency.
METHODSThe diagnosis of the disease mainly depends on the measurement of C3 (acylcarnitine), C3/C0 (free carnitine) and C3/C2 (acetylcarnitine) in the blood by tandem mass spectrometry, the detection of methylmalonic acid in the urine by gas-chromatography mass spectrometry, the determination of total homocysteine in the serum, and the loading test of vitamin B(12). The entire coding region of the MUT gene was screened by PCR combined with direct DNA sequencing in 21 isolated MMA patients. Novel mutations were identified by restriction fragment length polymorphism (RFLP) and sequence analysis in 100 controls.
RESULTSSeventeen MUT gene mutations were detected in 14 of the 21 patients, among them 8 mutations were novel, and R108H, D244LfsX39 and G544X were more frequent, with the frequencies of 9.5%, 7.1% and 9.5%, respectively. Most mutations were missense mutations (64.7%), and majority of them were in exons 2 and 3 (55.6%). Ten out of the 14 patients with MUT gene mutations had early-onset disease, while one case had late-onset disease, and the remaining 3 cases were detected by newborn screening. In addition, 11 of these 14 patients did not respond to vitamin B(12).
CONCLUSIONThis study revealed partial MUT gene mutation spectrum in Chinese patients with isolated MMA. The patients carrying MUT mutations often had early-onset disease, and most of them were VitB(12)- non-responsive.

Objective To explore the effect and mechanism of estrogen on endothelial progenitor cells(EPCs)function in diabetic rats. Methods EPCs were isolated from bone marrow of rats and characterized by fluorescence microscopy and flow cytometry. Rat diabetic model was established via streptozotocin induction. The bone marrow was taken to culture EPCs. EPCs of diabetes were incubated with Estrogen 10 nmol/L for 24h. The functions and proliferation of EPCs in vitro were detected. The levels of MnSOD and NO in EPCs and TSP-1 in supernatant were assayed. Results Compared with control group, EPCs proliferation, adhesion and angiogenesis functions were impaired in diabetic rats. The level of MnSOD and NO in diabetic EPCs were significantly decreased, while TSP-1 protein level in the supernatant increased. The above changes can be reversed with estrogen incubation. Conclusion Estrogen improved the EPCs migration and tubule formation in diabetic rats. The mechanism may be related to the reduction of oxidative stress and downregulation of TSP-1 expression in diabetic EPCs.
