Cancer Research and Clinic 2006;0(12):-
Objective To evaluate the clinical significance of orthotopic continent detenial sigmoid neobladder.Methods 12 patients with bladder cancer were admitted and underwent radical cystectomy and detenial sigmoid neobladder.Results All the 12 patients were followed up for a mean of 18.6 months(range from 6 to 29 months).The blood Cr and BUN levels were both in the normal range without acidosis in all the cases.Only 1 had unilateral ureteral urine reflux during cystography.Of the 12 patients,11 cases(91.7%) achieved continence during daytime;2 cases(16.7%)were incontinent at night,but 1 case could control uri- nation by being woken up at night.The capacity of the neobladder was 220 to 550ml with a mean of 350ml and the maximal pressure of the neobladder during filling was 15 to 55cm H_2O(1cm H_2O=0.098kPa)with a mean of 35cm H_2O.Conclusion As a simple operation the detenial sigmoid neobladder can be performed easily with less complications and more reliable results.This operation may be generally applied in clinical practice.

Objective To investigate the streptomycin(SM)-resistance of Mycobacterium tuberculosis (MTB) in urine and to examine their relationships with the mutation of rspL gene. Methods 47 strains of MTB were isolated from the urine of patients with renal tuberculosis.The mutation of rspL gene were analyzed by PCR-SSCP with silver-staining,and the strains were tested for the sensitivity to streptomycin. Results All the 47 strains had positive expression of rspL gene of MTB,with 28 SM-resistant and 19 SM-sensitive.Among the 28 SM-resistence strains 19(68%) had rspL gene mutation by SSCP testing.The 19 strains of SM-sensitive had no mutation. Conclusions Detecting mutation of MTB rspL gene in urine by PCR-SSCP can rapidly and exactly identify the MTB's sensitivity to streptomycin,which is significantly important in clinical treatment of anti-tuberculosis.

Objective:To evaluate the anti-tumor immune responses of nureplicable recombinant vaccinia virus-based vaccine expressing HPV16 L1 and L2E7 proteins.Methods:The anti-tumor effects of the vaccine were observed using mouse models of prophylactic,therapeutic and tumor excision.The cell-mediated immunity induced by the vaccine was assessed by enzyme-linked immunospot (ELISPOT) and cytotoxic T lymphocyte (CTL) assay.Results:The vaccine could protect 60% and 50% mice from the challenge of HPV16-positive tumor cells in prophylactic and therapeutic mouse model,respectively.It could protect from recurrence of the tumor in 70% mice of the excision model.The differences among the groups were significant.Strongly specific cell-mediated immunity was found using ELISPOT and CTL assay.Conclusion:The ideal anti-tumor immune responses can be induced by NTVJL1/L2E7 vaccine in mice and it can be considered to be one candidate vaccine of cervical cancer.

Tetrahydrobiopterin (BH4) is an essential cofactor for all three nitric oxide synthase (NOS isoforms), which plays an important role in vascular diseases. GTP cyclohydrolase 1 (GCH 1) is the first-step and rate-limiting enzyme for BH4 biosynthesis in its de novo pathway. Common GCH1 gene variant C+243T in the 3'-untranslated region predicts NO excretion. The present study examined the predictive role of GCH 1 gene 3'-UTR C+243T variant in the long-term outcome of ischemic stroke. A total of 142 patients with first-onset ischemic stroke were recruited and detected for genotype of GCH1 3'-UTR C+243T by a TaqMan SNP Genotyping assay. Subsequent vascular events and death were determined over a 5-year follow-up period. The frequency of GCH1 3'-UTR +243 C/T or T/T genotype was significantly increased in patients with endpoint events as compared with those without events (74% vs 57.8%, P=0.06). Cox regression survival analysis indicated that an increased probability of death or new vascular events was found in patients with GCH1 3'-UTR +243 C/T or T/T genotype compared with those with GCH1 3'-UTR C/C genotype (40.6% vs 25.5%), GCH1 3'-UTR +243 C/T or T/T genotype relative to GCH1 3'-UTR C/C genotype was associated with the increased risk of death or vascular events even after adjustment for other risk factors (OR=2.171, 95% CI: 1.066-4.424, P=0.033). It was concluded that GCH1 3'-UTR C+243T variant was an independent predictor of worsening long-term outcomes in patients with first-onset ischemic stroke.

This paper develops an intelligent NO delivery system cooperating with the ventilator to make NO inhaled safely, reliably, conveniently and economically, which is based on correlation between the parameter setup of the ventilator and the concentration of NO. The circuit control system consists of a mass flow controller and a CPU mainly. A mixing unit is designed to mix NO with the gas from the ventilator uniformly. Clinical experiments show that the NO from the intelligent delivery system can decrease PH and increase SaO2 with the concentration of generated NO2 less than 5ppm.

Objective To study the killing effects of the killer cell immunoglobulin-like receptors (KIR)2DS1-mediated natural killer (NK) cells against dendritic cells (DCs) and analysis the expression of chemokine receptor CCR7 after KIR2DS1-positive NK cells interact with the C2 epitope DCs in vitro,and explore the mechanism of alloreactive NK cell to limit graft-versus-host disease (GVHD).Methods NK cells were separated by Rosettesep NK sorting kit from healthy donor peripheral blood and taken as effector cells.The mononuclear cells from peripheral blood of newly diagnosed acute myeloid leukemia (AML) patients,and DCs were induced as target cells.Polymerase chain reaction and sequence specific primers (PCR-SSP) genotyping techniques and direct sequencing SBT were used to detect KIR gene,HLA-Cw of the healthy donors and patients.The cytotoxic activity of KIR2DS1-positive NK cells or KIR2DS1-negative NK cells against DCs were detected by CCK-8 assay.The expression of CCR7 after NK cells interacted with DCs was detected by flow cytometry.Results The purity of NK cells analyzed by flow cytometry was (94.20±1.23) %.Under same target ratio (10∶1),the killing effect of KIR2DS1+ NK cell against DCs was higher than that in KIR2DS1-NK cells (t =3.70,P < 0.05).Under same target ratio (10∶1),the cell lysis in C1/C1 group,KIR2DS1+ NK cells against C2/C2 group DCs (15.06±1.81) % was significantly higher than that against C1/C1 group (10.07±1.03) % and C1/C2 group (8.65±0.93) % DCs (F =56.368,P =0.001).KIR2DS1 + NK cells efficiently acquired CCR7 upon coculture with C2 epitope DCs.Conclusions NK cell expressing the KIR2DS1-activating receptor efficiently kill DCs,prevent GVHD,while enable NK cell acquire CCR7,obtaining migratory properties in vitro.
