Background Epithelial-mesenchymaltransition (EMT)isamajorcontributortothe pathogenesis of posterior capsular opacification(PCO).Kruppel-like factor 6 (KLF6) is a zinc finger protein,which can be stimulated by high glucose in proximal tubule cells and involved in transforming growth factor beta (TGF-β)induced EMT of diabetic nephropathy.ObjectiveThis study was designed to investigate the effect of high glucose on the expression of KLF6 and its target genes( TGFB1,TGFBR1,COLIA1,HSP47) in human lens epithelial cells (LECs).MethodsHuman LECs(SRA01/04) were cultured and exposed to different concentration of glucose.The expressions of KLF6 mRNA and protein were analyzed by real time polymerase chain reaction( real time PCR) and western blot after treatment with high glucose.The expressions of KLF6 target genes were analyzed by real time PCR to evaluate the EMT of SRA01/04 cells.ResultsCompared with the control group(5.5 mmol/L),the relative mRNA levels of t-KLF6 and wt-KLF6 in SRA01/04 treated with high glucose(22.2,44.4,66.6 mmol/L) increased obviously (F =72.53,42.02,P＜0.01 ).Then,the concentration of 22.2 mmol/L was used in the next experiments.The relative mRNA levels of t-KLF6 and wt-KLF6 increased to the peaks after treatment with high glucose for 12 h,and began to decrease after 24 h until lower levels after 48 h ( F =100.12,125.52,P ＜ 0.01 ).Western blot showed that the expression of KLF6 protein was also upregulated by high glucose treatment.With the promotion of the expression of KLF6 gene,the relative mRNA levels of TGFB1,TGFBR1,COLlAl and HSP47 of treated cells also respectively increased after treatment for 12 h,and began to decrease after 24 h until nearly at the levels of the control groups after 48 h( F=6.73,162.35,64.39,12.05,P＜0.05 ).ConclusionsIt was concluded that high glucose induced the expression of KLF6 in human LECs,and KLF6 transiently stimulated the expression of target genes TGFB1,TGFBRl,COLlAl and HSP47 which were mainly involved in the mechanism of EMT.

Objective Observe the results and reality of the peripheral nerve stimulator in the obtu- rator nerve block in TURBt.Methods 18 cases received the peripheral nerve stimulator in obturator nerve block before TURBt.Results In 17cases obturator nerve reflection vanished;lcase had a little symptom of adductor spasm.Conclusion Obturator nerve block with the help of the nerve stimulator can increase the achievement and quality of obturator nerve block and avoid some complications caused by obturator nerve re- flection in TURBt,such as perforation of bladder and injury of nerve and vessel.

Objective To evaluate the security and effect of combination of adjuvant hormonal thera- py and brachytherapy for localized prostate cancer.Methods 22 patients with T1-T2c prostate cancer were treated with transperineal ultrasound-guide 125I seeds prostate implantation and adjuvant hormonal therapy for 4～7 months.The hormonal therapy include 2-4 months before brachytherapy and 1～4 months after brachytherapy.Results The median operation time was ninety minutes,the median number of ~(125)I seeds used was 56.The follow up time was 12～48 months,the cases of PSA

Objective To study the relationship between fatty liver and blood lipids in children with simple obesity and the precaution of this disease.Methods Forty-eight cases from 2 to 16 years old with simple obesity were divided into 2 groups.The first group included 19 cases with fatty liver(38.78%);the second group included 29 cases without fatty liver(61.22%). Blood lipids in 2 groups were analyzed with biochemical method.Blood total cholesterol(TC),triglyeride(TG),high density lipoprotein(HDL) and low density lipoprotein(LDL) were detected and the liver was examined with ultrasound.Results Blood TC,TG,HDL and LDL in cases with fatty liver were higher than those wit-hout fatty liver.Blood TG had the closest relation with fatty liver(P_a

Objective To analyze blood lipid components in simple obesity children and to explore the effects of obesity in the lipid metabolism and its clinical significance.Methods A total of 90 children,including 50 simple obesity children(obesity group)and 40 normal children(control group),were enrolled in this study.The age ranged from 2.5 to 16.0 years.Their blood lipid profiles of all the children were analyzed.The blood lipid profiles were examined by biochemical analysis,including triglyeride(TG),total cholesterol(TC),low density lipoprotein(LDL) and high density lipoprotein(HDL),and the livers of all the children were analyzed.The blood lipid profiles were examined by ultrasonograph.Results 1.There were no significant differences in age and height in obesity group and control group,but there were significant differences in body mass index(BMI) and blood pressure(P0.05),which had no statistical meaning.3.Liver ultra sonogram showed that 18 cases had fatty liver(36%) in simple obesity children.Conclusions Metabolic disorder of blood lipid is present in simple obesity children,who have a tendency to get fatty liver.LDL is markedly elevated in obesity group.Arteriosclerotic cardiovascular disease should be prevented at earlier period of childhood.

The biological artificial liver(BAL) can offer reliable artificial liver support for the patients with hepatic failure.All BAL devices contain hepatocytes as their biological component,whose specific biological characteristics contribute to the function of the BAL.During the past two decades,various cells including human hepatocytes,heterogeneous hepatocytes and liver cell lines have been used and different culture methods have been studied to optimize the activity of the biological component.However,both functionality and safety of these cells should be improved before successful use in BAL. This paper summarizes the latest progress on it.

The technique introduced in this paper is applied in the endocardial catheter operation, which describes the 3D heart model reconstruction before the operation for the endocardial navigation. After a series of CT images of the thorax are processed, an accurate 3D endocardial model can be reconstructed. At first, the series of 2D CT images are preprocessed for denoising and the enhancement,then they are constructed as the volume data. After the region growing segmentation in the 3D volume data according to the grey value of the voxel in the heart cavity, the heart surface rendering is got and the 3D model of endocardial cavity is reconstructed.

Objective:To investigate the therapeutic efficacy of double-J catheter in treatment of renal tuberculosis(TB)and in rescuing the structure and function of the kidney.Methods:Thirty-four patients with renal TB(22 combined with single side hydronephrosis)were divided into 2 groups randomly.Group A were treated with antituberculous therapy and group B with antituberculous therapy combined with pre-treatment with double-J catheter.All 34 patients were followed up for 3 months and were re-examined.Results:The results of B ultrasound,intravenous urogram(IVU),CT and isotope nephrogram were comparable between the 2 groups before treatment,and the results were significantly different between the two groups after 3 months'drug treatment(P
