Objective To investigate the clinical features and gene mutation of a newborn with neonatal-onset ornithine transcarbamylase deficiency (OTCD) and report the multidisciplinary perinatal management of the mother with late-onset OTCD.Methods The clinical features,biochemical data and the treatment of a newborn boy with OTCD and his mother admitted by Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine in April,2013,were collected.The ornithine transcarbamylase (OTC) gene in the family was analyzed.Results Serum ammonium in the male newborn gradually increased to 1 020 μ mol/L at 48 h after birth.His blood amino acids level and urine organic acid level showed a pattern indicative of OTCD [blood arginine (97.43 μ mol/L,reference 1.00-25.00 μ mol/L),citrulline (27.43 μ mol/L,reference 4.00-30.00 μ mol/L),ornithine (161.66 μ mol/L,reference 10.00-120.00 μ mol/L) and methionine (70.45 μ mol/L,reference 10.00-50.00 μ mol/L); urine uracil (67.11 μ mol/mol Crea,reference 0.00-7.00 μ mol/mol Crea) and orotic acid (1 372.66 μ mol/mol Crea,reference 0.00-1.50 μ mol/mol Crea)].DNA studies revealed a c.583G ＞ A (G195R) homozygous mutation of the OTC gene.His mother was heterozygous for OTCD and developed acute hyperammonemia during pregnancy.Her blood showed a normal-leveled arginine (8.44 μ mol/L,reference 1.50-25.00 μ mol/L),a normal-leveled citrulline(8.41 μ mol/L,reference 7.00-35.00 μ mol/L),an elevated glutamate(279.15 μ mol/L,reference 45.00-200.00 μ mol/L).Her urine uracil (51.55 μ mol/mol Crea,reference 0.00-7.00 μ mol/mol Crea) and orotic acid (38.75 μ mol/mol Crea,reference 0.00-1.50 μ mol/mol) were elevated.Successful management of her prenatal and postpartum blood ammonia level was achieved after administration of pharmacologic nitrogen scavengers and protein limitation.DNA studies revealed a c.583G ＞ A (G195R) heterozygous mutation in the newborn's mother and grandmother.Conclusions General management on pregnant OTCD women is effective.Male newborn patients often have a poor prognosis.

Objective To explore the role of Hippo pathway in the pathogenesis of autosomal dominant polycystic kidney disease (ADPKD),and find potential targets for drug therapy.Methods By means of immunofluorescence staining,Western blotting,Real-time PCR,the differences of sublocalization,expression and phosphorylation level about Hippo pathway molecules in Han:SPRD (cy/+) and ADPKD patients compared with the control were observed.Knockdown Yes kinaseassociated protein (YAP),transcriptional coactivator with PDZ binding motif (TAZ) and large tumor suppressor kinase1 (LATS1) in cystic lining epithelium cell line WT9-12 were took by siRNA interference,and then their effects on cell proliferation,apoptosis and cell cycle were assessed.Results In cystic lining epithelium of Han:SPRD(cy/+),decreased expression of LATS1 and increased expression of YAP were found compared with the control,and the immunofluorescence of YAP was distributed both in cytoplasm and nucleus,while distribution and expression level of TAZ were without significant variance.Abnormal mRNA expressions of Hippo pathway components in ADPKD patients were found (P ＜ 0.05).Down-regulation of LATS1 in WT9-12 cells could prohibit phosphorylation of YAP,and prompted proliferation and cell division.Knockdown YAP in WT9-12 cells could inhibited cell proliferation by arresting cell cycle in G0/G1 phase,but down-regulating TAZ showed no significant differences in proliferation and cell cycle.Conclusions Altered Hippo signaling exists in ADPKD,and YAP activation may be one leading cause of autosomal dominant polycystic kidney disease onset.In vitro,knockdown YAP in WT9-12 cells can inhibit cell proliferation by arresting cell cycle and depressing cell division,suggesting the expression level and activity of YAP are potential targets for ADPKD treatment.

Objective To investigate the changes in concentrations of the homocysteine (Hey) and other aminothiols (ESRD) in plasma of end-stage renal disease (ESRD) patients before and after hemodialysis (HD). Methods 26 chronic renal failure patients treated with hemodialysis plus 54 healthy controls were randomly chosen. The concentrations of plasma total homocysteine (they), total cysteine ( tCys), total cysteinylg]ycine (tCysGly), total glutathione (tGSH) were determined by HPLC-fluorescence detection (FD). The concentrations of serum lipids were detected and several renal function tests were conducted. Results The concentrations of they ( 16. 70 ± 3.51 μmol/L vs 10. 95±3.07 μmol/L, t =3. 625,P <0. 01),tCys(341.87±70.65 μmoL/L vs 249.76 ± 13.18 μ mol/L,t =6.219,P <0.01), tCysGly(41.33 ± 32. 95 μmol/L vs 31.3 ± 11.78 μmol/L, t = 3. 530, P <0.01 ) in pre-hemodialysis plasma were significantly elevated , and tGSH ( 5.91 ± 0. 08 μmol/L vs 9. 33 ± 2. 62 μ mol/L, t =-5.404, P < 0. 01 ) was significantly decreased compared with the control group. The concentrations of tHey and tCys (11.74 ± 3.42 μmol/L and 272. 67 ± 64. 18 μmol/L) in post-hemodialyais plasma were significantly decreased compared with in pre-hemodiaIysis plasma, but they could not be restored to normal levels. However, the concentrations of tCysGly(41.33 ± 32. 95 μmol/L vs 44. 93 ± 13.88 μmol/L,t =-0.758, P>0.05) and tGSH (5.91±0.08 μmol/L vs 5.93±0.38 μmol/L,t = -0.068,P >0.05) in pre-hemodialysis plasma and post-hemodialysis plasma didn't change significantly. There were significant positive correlations between plasma levels of they and tCys(r =0. 458 2 ,P <0. 01 ). There was significant negative correlations between plasma levels of tHcy and tGSH ( r =-0.609 9, P=0.000 9). Nevertheless, tHcy levels were was not correlated with tCysGly levels and other serum lipid parameters. Conclusion There is a high prevalence of metabolic disturbance in Hcy and other related aminothiols in ESRD patients.

Objective To investigate the hyper-variable region-polymerase chain reaction(HVRPCR) genotype of methicillin-resistant Staphylococcus aureus (MRSA) in local hospitals in Hunan province, and to compare it with the antibiograms, and to preliminarily discuss its role in molecular epidemiology of MRSA. Methods A total of 80 MRSA clinical isolates were collected from three affiliated hospitals of Central South University. Their DNA were extracted and amplified by PCR. The genotype was classified by the fragments of amplified products based on the size of HVR. The drug sensitivity test of MRSA was performed, and the correlation of genotypes and antibacterial resistance was analyzed. Results Eighty strains of MRSA were divided into 5 HVR genotypes which were named as A, B, C, D and E respectively according to the size of the PCR products. The most common types were D (61.25%) and E (21.25%), followed by A (3.75%), B (5.00%) and C (8.75%). Most strains of genotypes were multi-drug resistant but all strains were sensitive to vancomycin. Conclusion These results suggest that HVR-PCR genotype method is a rapid, convenient and effective method for epidemiological investigation of infections caused by MRSA, and it is also helpful for clinical selection of antibacterial agents in effective treatment of MRSA infection.
