Objective: To investigate the cytotoxicity of ICE gene transfection in Combination with Antitumor Chemicals killing Hepatocellular Carcinoma Cells in vitro.Methods: The recombinant plasmid pLXSN-hICE was transferred to virus packing cell PA317 by electroporation method. And then the retrovirus containing human ICE cDNA generated by these PA317 cells were used to transfect human hepatocellular carcinoma cell line HepG2. The apoptosis of transferred cells were examined by gel electrophoresis. The influence of chemotherapeutic drug Carbo-platin to the proliferation of hepatocellular carcinoma cell line SMMC7721 and its derivative cells(SMMC7721-hICE,SMMC7721-antisence hICE,SMMC7721-neo)was observed by incorporation of 3H-TDR. Results: Electrophoresis of DNA displayed the apoptosis ladder of HepG2 transfected by ICE gene. The proliferation of SMMC7721-hICE was significantly suppressed in vitro induced by Carbo-alatin compared to the other three cell lines. Conclusion: ICE gene transfection could greatly increase the susceptibility of SMMC7721 cells to apoptotic cell death following chemotherapy. These findings suggest that combining ICE gene transfection with utilizing antitumor drugs would represent a novel approach for the effective treatment of hepatocellular carcinoma.

Objective To observe the effect of fleabane injection on serum level of D-dimer, fibrinogen and hypersensitive C-reactive protein in patients with IgA nephropathy and to explore the mechanism of fleabane injection for treating IgA nephropathy. Methods 29 patients with IgA nephropathy were given fleabane injection together with routine treatment. Another group of 28 patients with IgA nephropathy were only treated with routine treatment as con-trol. Determinations of 24 hours urine protein output(24HPQ), serum level of D-dimer(D-D), Fibrinogen(Fib) and hypersensitive C-reactive protein (hsCRP) were carried out pre- and post-study. Results Significant decrease in 24HPQ , serum level of D-D, Fib and hsCRP were observed in both treatment group and control group(P <0. 01 ～0. 05), but more significant in treatment group as compared with control group ( P < 0. 05). Conclusion Flea-bane Injection plus routine treatment could significantly decrease 24HPQ in patients with IgA nephropathy, and this maybe contribute to regulation of D-D, Fib and hsCRP by fleabane injection.

Objective:To explore the feasibility, safety and clinical efficacy of ileum augmentation cystoplasty assisted by Da Vinci robot for the treatment of neurogenic bladder.Methods:Retrospective analysis was performed on the data of 12 patients with neurogenic bladder admitted to Zhejiang Provincial People’s Hospital from March 2017 to November 2018, including 11 males and 1 female, with the mean age of 38(12-67). Preoperative symptoms were urinary incontinence, dysuria, decreased bladder capacity, or increased bladder pressure leading to ureteral reflux. All the 12 patients underwent preoperative intermittent catheterization, including 8 patients with spinal cord injury and 4 patients with spinal cord dysplasia. Preoperative serum creatinine(129.58±44.60)μmol/L and total glomerular filtration rate(61.63±18.04)ml/(min·m 2) were observed in 12 patients. Preoperative urodynamic examination showed the safe bladder volume of (95.67±39.10)ml, bladder internal pressure of(63.30±6.02)cmH 2O(1 cmH 2O=0.098 kPa)at the end of filling period, bladder compliance of(10.24±1.14)ml/cmH 2O, residual urine volume of(152.58±80.89)ml, and urine flow rate of(3.88±3.63)ml/s. Bladder contracture was evident on preoperative cystography. Ultrasound examination showed different degree of hydronephrosis and ureter expansion, in all cases, with ureteral reflux grading Ⅰin 2 cases, grade Ⅱ in 4 cases, grade Ⅲ in 4 cases, grade Ⅳ in 2 cases. All the 12 patients underwent robot-assisted ileum augmentation cystoplasty with 5-point puncture. Transverse incision of the bladder wall before full thickness, according to the amount of bladder and quality to decide 30 cm(normal), longitudinal cut back loops and one point after suture fixation in the bladder wall midpoint, fixed point as starting point, in turn, will be blind to the bladder stitching on both sides, the bilateral ureteral placing a single J tube respectively, evaluation of surgical success rate (including intraoperative bleeding, interception of bowel loops are no damage adjacent viscera, ureter openings with and without damage, impermeability, match insufflate whether unobstructed), postoperative complications, anastomotic fistula, intestinal obstruction, abdominal bleeding), urine dynamics test parameters, and patients’ quality of life. Patients were regularly given anticholinergic drugs(2 mg/d) for 6 months after surgery. Results:All the 12 cases in this group were successfully completed without any transfer to open surgery. The operation time was(120.8±12.0)min. Intraoperative blood loss(84.0±23.2)ml. Postoperative intestinal function recovery time(3.3±1.3) d. Postoperative hospital stay(12.1±3.1)d. Postoperative pelvic drainage tube indwelling time (3.8±1.2) d. Catheter and single J tube were removed 2 weeks after operation. Postoperative follow-up averaged 19.4(3-24) months. At 3, 12, 24 months after surgery, the bladder safety volume was rechecked(435.83±33.56), (450.90±31.09), (462.00±33.72)ml, the bladder internal pressure at the end of filling was(18.60±0.92), (15.70±1.42), (12.96±1.34)cmH 2O, the blood creatinine level was(81.43±21.10), (74.34±15.70), (72.90±15.90)μmol/L, and the bladder compliance was(37.94±4.22), (40.40±3.98), (43.42±4.20)ml/cmH 2O and the total glomerular filtration rate(91.52±9.49), (102.18±5.65), (112.41±6.50)ml/(min·m 2) were significantly improved compared with those before surgery( P<0.001). After 24 months of bladder urination training, 1 patient could basically urinate by herself. Three patients were treated with intermittent urinary catheterization supplemented by automatic urination. The remaining 8 patients were completely dependent on urinary catheter for intermittent catheterization. Postoperative complications such as anastomotic fistula, ileus and abdominal bleeding were not found in 12 patients. Conclusions:Ileum bladder enlargement assisted by robot can effectively expand bladder volume, reduce bladder internal pressure, improve bladder compliance, prevent ureteral reflux and protect renal function.

OBJECTIVETo explore the linkage relationship between specific genetic markers and arrhythmogenic right ventricular cardiomyopathy (ARVC) in Chinese pedigrees.

METHODSThe microsatellite genetic markers D2S152, D14S252, and D10S1664 were studied for their linkages to ARVC in five Chinese ARVC pedigrees and a normal population of 121 Chinese individuals. Genomic DNA of the pedigrees and normal population was amplified using PCR techniques. Denaturing polyacrylamide sequencing gel (4%) electrophoresis was used to detect microsatellite repeat polymorphisms. Gels were silver-stained. A classical linkage analysis program was used assuming models of autosomal dominance and recession.

RESULTSThe logarithm of the odds (LOD) scores of D2S152 with ARVC in LW, WD, DS, LC and TY pedigrees were 2.174, -0.589, -infinity, - (indicating that linkage is not supported in this mode), and -infinity respectively in autosomal dominant model (recombination fraction = 0.000 respectively)and were -infinity, -infinity, -infinity, -infinity, and 0.182 respectively in the autosomal recessive model. The LOD scores of D14S252 with ARVC in LW, WD, DS, LC and TY pedigrees were -, -, -infinity, -, and 0 respectively in autosomal dominant model, and were -infinity, -0.812, -infinity, -infinity, and 0.087 respectively in autosomal recessive model. The LOD scores of D2S152 with ARVC in LW, WD, DS, LC and TY pedigrees were -, -0.539, -, and 0.602 respectively in autosomal dominant model and were -, -infinity, -infinity, -infinity, and - infinity respectively in autosomal recessive model.

CONCLUSIONSThe LOD score for D2S152 in the LW pedigree was 2.174, indicating that the chance of linkage is about 150:1. This suggests that there is a possible ARVC-related gene near this marker. There were no clear linkage relationships between ARVC and D10S1664 and D14S252 in this family, and no linkages between ARVC and any of the three genetic markers in the other four families. These results also suggest that there is genetic heterogeneity in LW and in the other pedigrees.

In this paper, we propose the construction of a fifth-order Windkessel model, and give complete mathematical solutions for this model. Utilizing the diastolic pulse wave analytical methods, we derived the parameters of the mathematical model. The parameters were further applied to estimate arterial compliance, blood flow inertia, peripheral resistance and other indices. With simulation tools we assess the validity of the model, and built a simulation circuit with the model parameters R, C and L. The model parameters were obtained from the high-order Windkessel model. The stroke volume of left ventricle is employed as the input of the simulation circuit. At the end of the circuit, the responding signal was gained. And it in turn was compared with the measured pulse waveform. The results show that the fifth-order Windkessel model is superior to the third-order Windkessel model in the pulse wave fitting and stability, and thus better reflects the role of microvessles in the circulatory system.
