Objective To evaluate the clinical value of percutaneous transcatheter selective right portal vein embolization(PVE)in treatment of primary hepatocellular carcinoma.Methods Twelve patients with unresectable hepatocellular carcinoma were treated with right percutaneous transcatbeter PVE under fluoroscopic guidance.Left hepatic lobe volume was measured by CT before and after PVE.Portal vein pressures and changes of liver function were also detected before and after the embolization.Results Right portal vein was embolized successfully in all 12 patients with compensatory hypertrophy of left hepatic lobe.Right hepatic lobe was successfully resected in 3 patients.There were no evidence of hepatic dysfunction and portal hypertension after PVE and also without complication.Conclusions Percutaneous transcathter portal vein branch embolization can induce atrophy of the embolized lobes with compensatory hypertrophy of the remnant liver,providing another operation chance for patients with unresectable hepatocellular carcinoma.

OBJECTIVESTo investigate the effects of FAK-related non-kinase (FRNK) on expressions of type I collagen and matrix metalloproteinase-2 (MMP-2) mRNA and tissue inhibitor of metalloproteinase-2 (TIMP-2) mRNA in rat hepatic stellate cells (HSC).

METHODSUsing in vitro cell culture technique, FRNK plasmids were transfected into HSC mediated by cationic liposome. Type I collagen synthesis capability in HSC was examined by 3H-Pro incorporation assay. The levels of FRNK in HSC were assayed by Western blot, and the expressions of MMP-2 and TIMP-2 were assayed by RT-PCR on mRNA levels.

RESULTSThe exposure of HSC to FRNK caused the expression of FRNK protein to be up-regulated, and the FRNK protein contents reached the highest point at 48 h after the transfection, P less than 0.05. The expressions of MMP-2 mRNA were up-regulated by FRNK; the expressions of TIMP-2 mRNA were down-regulated by FRNK; the ratios of MMP-2 mRNA/TIMP-2 mRNA were enhanced by FRNK.

CONCLUSIONAfter FRNK was transfected, the capability of type I collagen synthesis in HSC was inhibited, which may be related to the up-regulation of MMP-2 mRNA/TIMP-2 mRNA.

OBJECTIVEAutosomal recessive steroid-resistant nephrotic syndrome (SRNS) is a subgroup of familial nephrotic syndrome. A causative gene has been identified, that is NPHS2, in chromosome 1q25-31, which encodes podocin. This study aimed to detect NPHS2 mutation in a Chinese family with SRNS.

METHODSRenal biopsy was performed on the proband and her sibling for routine histologic and immunohistochemical investigation and electron microscopic examination. The expressions of podocin, nephrin, alpha-actinin and WT1 in glomeruli of the proband were detected by indirect immunofluorescence. Peripheral blood samples were collected for genetic analysis from the proband and her parents, and 53 adults with normal urinalysis. Genomic DNA was isolated from peripheral blood leucocytes. Eight exons of NPHS2 were amplified by polymerase chain reaction. Mutational analysis was performed using denaturing high-performance liquid chromatography (DHPLC) and DNA fragments with aberrant elution profiles of both strands revealed by DHPLC were re-amplified and sequenced directly.

RESULTSThe histologic findings on kidney biopsies were focal segmental glomerulosclerosis. In controls, the distribution of staining with P35, rabbit against a human podocin recombinant protein (amino acids 135 - 383 = all the C-terminal part of the protein downstream the transmembrane domain), and P21, rabbit against a human podocin recombinant protein (amino acids 15 - 89 = all the N-terminal part of the protein upstream the transmembrane domain) showed a linear pattern along glomerular capillary walls on glomeruli, and the fluorescent intensity of the staining with P35 was intensely positive. The fluorescent intensity of the staining with P21 was positive. In the proband, the distribution of the staining with P35 showed uneven and nonlinear, and the fluorescent intensity of the staining with P35 was weakly positive. The staining with P21 was negative. The area, location, distribution and fluorescent intensity of the staining with nephrin, alpha-actinin and WT1 on glomeruli of the proband were the same as those in the controls. The DHPLC elution profiles of exon 4 of NPHS2 from the proband and her parent were aberrant. The chromatograms by sequencing detected in the exon 4 of NPHS2 showed a composite heterozygous mutation of both 467_468insT and 503G > A in the proband, a heterozygous mutation of 503G > A in her father, and a heterozygous mutation of 467_468insT in her mother, respectively.

CONCLUSIONThe study demonstrated for the first time a novel mutation, 503G > A, of NPHS2 in Chinese kindred with autosomal recessive SRNS. A significantly decreased or negative expression was also revealed in glomeruli of the proband stained with two kinds of anti-podocin antibodies.

OBJECTIVETo evaluate the enhancing effects of ginsenoside Rg3 combined with mitomycin C and tegafur (MF) on postoperative chemotherapy in advanced gastric cancer.

METHODSSeventy-one postoperative patients with advanced gastric cancer were randomly divided into two groups, the control group (n=33), which received treatment with only MF (Mitomycin C+Tegafur), and the trial group (n=38), which were treated with ginsenoside Rg3+MF. The serum VEGF levels in the control group and trial group were detected preoperatively and postoperatively, meanwhile, the serum VEGF levels in 30 healthy persons were detected as comparison. The relations between patients survival and serum VEGF levels were analyzed.

RESULTSThe levels of serum VEGF in advanced gastric cancer were higher than those in healthy persons [(297.8+/-129.6) pg/ml vs (212.3+/-67.5) pg/ml] (P<0.01), and were correlated with the depth of tumor invasion, lymph node metastasis, tumor size > 4 cm and TNM stage (P<0.05). Fourteen weeks after operation, the levels of serum VEGF in trial group decreased below those of preoperation and approached to normal range, while in the control group, the levels of serum VEGF decreased near those of preoperation only. The median survival of patients in trial group and control group were 40 and 25 months respectively. The survival rate of patients in trial group was significantly higher than that in control group (P=0.047).

CONCLUSIONThe combined application of ginsenoside Rg3+MF chemotherapy can decrease the concentration of serum VEGF and improve the survival rate in advanced gastric cancer patients.

Objective To investigate the distribution of integrons and ISCR1 elements in NDM-l-producing Citrobacterfreundii isolates,and analyze the genotypes of these strains to understand their homology.Methods A total of 18 strains of NDM-1-producing Citrobacterfreundii were collected from the First Affiliated Hospital of Kunming Medical University during the period from June 2012 and October 2014.The isolates were identified and subjected to antimicrobial susceptibility testing with VITEK 2 System.Class Ⅰ,Ⅱ,and 1Ⅲ integrons and ISCR1 elements were detected by PCR.Clonal relatedness was assessed by pulsed field gel electrophoresis (PFGE).Results Most (77.8％,14/18) strains were positive for class Ⅰ integron conserved region,27.8％ (5/18) isolates were positive for ISCR1 conserved region.No class Ⅱ or Ⅲ integron was detected.Most (72.2％,13/18) isolates were positive for class Ⅰ integron variable region.None of the strains harbored class Ⅱ integron or ISCR1 variable region.Integron variable regions included gene cassette encoding resistance to aminoglycosides (aadA1,aadA5,aac(6')-Ib-cr) and trimethoprim-sulfamethoxazole (dfrA,dfrA15,dfrA17).PFGE revealed 17 clusters among 18 NDM-l-producing Citrobacter freundii isolates.Conclusions The clonal dissemination of NDM-l-producing Citrobacterfreundii isolates is not significant.Class I integron is prevalent in NDM-l-producing Citrobacter freundii.The presence of ISCR1 is relatively rare.The two mobile elements are not related to the spread of NDM-1 gene in this hospital.
