Objective To assess the outcome of vesicoureteral reflux after augmentation cystoplasty in patients with neurogenic bladder.Methods Between January 2008 and January 2014,a total of 25 patients,with a hypocompliant bladder associated with vesicoureteral reflux confirmed by video-urodynamics preoperatively,were recruited in this study.They all had undergone bladder augmentation with a generous detubularized segment of bowel at our institution.No effort had been made to correct existing reflux.Preoperatively assessment included urinalysis,kidney function tests,ultrasonography,video-urodynamic evaluation.All patients had various degrees of vesicoureteral reflux.The status of vesicoureteral reflux and bladder function were studied by video-urodynamic.Results Mean follow-up was 2.2 years (range 0.5 to 5.5 years).The video-urodynamics manifested a significant improvement of bladder capacity,diminution of intravesical pressure and resolution of reflux after bladder augmentation.Of the 25 patients,20 (80％) no longer had reflux,3 (12％) had improvement,2 (8％) had no change.Sixteen of 18 with grades Ⅰ to Ⅲ (89％),all refluxing units with grade Ⅳ to grade Ⅴ (100％) showed complete cessation of reflux.Symptomatic urinary infection was not found after surgery.Conclusions Augmentation enterocystoplasty without ureteral reimplantation is effective and adequate for patients with high pressure and hypocompliant neurogenic bladder.Therefore,ureteral reimplantation is not necessary underwent when augmentation enterocystoplasty is recommended to patients with neurogenic bladder and vesicoureteral reflux.

There are multimechanism and multipathogens in the course of the progress and the metastasis of hepatocarcinoma. Growth factors play an important role in the process. In this review, the relationship between growth factors and hepatocarcinoma are summarized.

AIM: To investigate the possibility of 3T3 fibroblast growth on blood fibrin clot in culture medium with recombinant human basic fibroblast growth factor (rhbFGF). METHOD: Growth of the cells on blood fibrin clot was studied by phase-contrast, scanning and transmission electron microscopy and by Giemsa stain and MTT assay. RESULTS: The optimal concentration of rhbFGF for proliferation and survival of the cells was 100 ng/mL. The cells also grew on blood fibrin clot scaffold in the low-serum medium containing 100 ng/mL rhbFGF, and a greater number of the cells survived after 48 hours incubation compared to that after 24 hours. The elongated filopodia appeared to bridge the gaps among the fibroblasts after 24 hours incubation. Further incubation to 72 hours, a greater number of platycytes were found to be joined together by lamellopodia. CONCLUSION: 3T3 fibroblasts could grow and survive on blood fibrin clot in the low-serum medium containing rhbFGF, and a combination of blood fibrin clot and rhbFGF may have over proportional effects on wound healing.

Basic fibroblast growth factor (bFGF) has been used in wound healing, bone healing, vascular grafting, lens regeneration and limp regeneration. Anti-bFGF antibody is thought to be an major important reagent for bFGF research. This review summarizes the development of anti-bFGF antibody in recent years including preparation, screening, identification and application in order to provide reference to the studies of this field in our country.

BACKGROUND: The understanding about characteristics and variation trends of cerebral vascular hemodynamic indexes in high-risk stroke population,in prior and post-stroke period patients as well as in normal people,particularly the cerebral vascular hemodynamic index(CVHD) prior to stroke can improve diagnosis efficiency of stroke and increase sensitivity and specificity of stroke diagnosis.OBJECTIVE: To study the features of CVHD in acute stoke,in order to provide evidences for early evaluation and rehabilitation intervention.DESIGN: Case analysis and observational study based on patients.SETTING: A neurological department in a general hospital of military area command of Chinese PLA and a prevention and cure institute of cerebrovascular diseases.PARTICIPANTS: Totally 55 (male 38,female 17) inpatients in the Neurological Department of Fuzhou General Hospital of Chinese PLA from June to December 2001 were enrolled in the study.METHODS: CVHD was measured during the first week after onset and the data were analyzed.MAIN OUTCOME MEASURES: The CVHD,blood pressure and cerebral vascular hemodynamic parameters.RESULTS: The CVHD of each patient is below 75,median 32.5. The mean velocity,blood flow,maximum velocity,minimum velocity and difference between diastolic and critical pressures were lower than corresponding ones of healthy men in seventies( P ＜ 0.01 ). And the pulse wave velocity,peripheral resistance,specific impedance and critical pressure increased( P ＜ 0. 01).CONCLUSION: During the first week after stroke,the CVHD decreases and many hemodynamic parameters alters significantly. Examination of CVHD can reveal cerebral circulation insufficiency or predict an attack of cerebral stroke.

Objective To study the effect of blood glucose level and duration of type 2 diabetes mellitus on carotid intima-media thickness (CIMT) and quantitative carotid stiffness (QCS) in the patients with type 2 diabetes mellitus. Methods Two hundred and seventy-four type 2 diabetic patients (diagnosed according to the World Health Organization criteria) were involved in this study. The subjects were divided into three groups according to the HbAlclevels and duration of diabetes mellitus: 60 with duration ≤2 years (as newly diagnosed) , 96 with duration≥5 years and HbAlc <6.5%, and 118 with duration≥5 years and HbAlc≥6.5%. CIMT and QCS of the common carotid artery were assessed by the high-resolution B-mode ultrasound unit and an echo-tracking system integrated in an uhrasound unit respectively. Results (1) In categorical analyses, the mean level of CIMT was increased from 720 μm in subjects with a duration of diabetes mellitus ≤2 years to 770 μm in subjects with a duration of diabetes mellitus > 2 years and plasma HbAlc< 6.5% (P < 0.05), and to 800 μm in subjects with a duration of diabetes mellitus > 5 years and plasma HbAlc≥ 6.5 % (P < 0.01). The corresponding values for Q CS values were 4.5, 4.5 and 5.1 (P <0.05), respectively. (2) In multiple stepwise regression analyses, CIMT wassignificantly associated with the duration of diabetes mellitus, systolic blood pressure and serum concentration of total cholesterol, whereas QCS was significantly associated with age, duration of diabetes mellitus, smoking, HbAlc, systolic blood pressure (P < 0.05 or P < 0.01). Conclusion QCS is suitable in evaluating the impact of blood glucose on carotid artery, while CIMT is an appropriate tool for long-term follow-up of diabetic patients.

AIM: To investigate the behaviour of 3T3 fibroblast and macrophage co-culture on blood fibrin clot or adipose tissue with recombinant basic fibroblast growth factor (rhbFGF). METHODS: MTT method, inverted contrast microscopy, Giemsa staining as well as scanning electron microscope were used in the present study. RESULTS: The effect of rhbFGF on co-culture of 3T3 fibroblast and mouse macrophage on blood fibrin clot in low-serum DMEM with rhbFGF were monitored, and 3T3 fibroblast and macrophage growed well on the blood fibrin blot in low-serum DMEM with rhbFGF. CONCLUSION: The blood fibrin clot, with its low immunogenicity, could be used as a bionic support for three-dimensional tissue culture, and also a physiological carrier to distribute the growth factor rhbFGF for the cells.

Objective To establish an accurate TaqMan probe real-time quantitative PCR (qPCR)method for detection of Theiler''s-like virus of rats (TLV).Methods Primers and TaqMan probes specific to 3622~3729 nt region were designed according to the whole genomic sequence of TLV representative strain.Using a synthesized plasmid as DNA standard template, the stability, specificity, and sensitivity of the qPCR method were determined.Results In the standard curve, R2 value was 0.99 with a high specificity.The sensitivity of the real-time PCR was less than 10 copies/μL, which was 100 times higher than the ordinary PCR method.No cross reactions appeared to the other rat viruses.Conclusions The TaqMan probe qPCR method established in this study has advantages such as simple to use, high sensitivity and specificity.
