Objective To investigate the clinical value of selective arterial embolization in the emergent treatment of traumatic urinary bleeding. Methods Twenty-seven cases were included in the study. The bleeding arteries were determined according to findings in angiography and embolic agents (gelfoam particles or steel coils) were inserted into the target arteries. Results The hemorrhage was completely controlled in 23 cases after the first embolization and in 2 cases after the second embolization. The embolization failed and was converted to open surgery in 2 cases. Adverse effects after the embolization included 16 cases of fever, 14 cases of local pain with nausea and vomiting, and 1 case of transient buttock pain after the embolization of the internal iliac artery). Conclusions Selective arterial embolization is an effective and mini-invasive option for the management of traumatic urinary bleeding. It takes effect quickly and creates favorable conditions for further treatment.

Objective The aim of our study is to differentiate left atrial from right atrial tachycardia on the basis of P wave configuration during focal atrial tachycardia (AT).Methods Thirty-three patients with focal atrial tachycardia who had undergone successful radiofrequency catheter ablation were considered for inclusion in the study . Site of origin was the left atrium in 10 patients, and right atrium in 23 patients . The surface 12-lead ECG recordings during atrial tachycardia were reviewed in all patients. We analyzed the correlativity between P wave configuration and left atrial tachycardia.Results The specificity of negative P wave in lead I and aVL that indentifed a left atrial focus was 100% and 95% respectively, but the sensitivity was only 30% and 50% respectively. The specificity and sensitivity of positive P wave in V 1 that predicted a left atrial focus was 87% and 80%,respectively.Conclusion It is possible to predict the site of origin of focal atrial tachycardia by analyzing its P wave configuration,,and may be helpful for preparation before ablation.

We describe a modified technique for the in vitro study of human spermatozoal penetration into hamster oocytes which is easier to master and more simple to perform and needs no complicated facilities.It comprises the following aspects:1 The hamster oviduct is stained with 1％ neutral red agar slics, so that the opening of the oviduct is easy to find and easy to be inserted with needle for flushing eggs.2. A special small tube,3 cm long with a diameter of 0.5 cm is used for fertilization instead of plastic dish with paraffin oil covering the media.3. Ordinary incubator is used rather than CO_2 incubator. With these procedures, the sperm penetration rates we got were 75％, 25％, 40％, 80％ and 46％ respectively in 5 experiments. It could meet the needs to evaluate the fertilizing capacity of human spermatozoa.

Objective To evaluate the application of the transurethral vapor-resection of the prostate(TU- VRP) for bladder outlet obstruction(BOO) in patients with prostate eaneer(PCa). Methods Of 33 patients with BOO. 18 were definitely diagnosed with PCa and after treatment they still had symptoms of BOO;15 cases were di- agnosed with benign prostate hyperplasia(BPH). All patients underwent TUVRP for BOO. Results All cases were successfully done. Postoperative complications included transient urinary ineontinenee in 5 ,and gross hematuria in 9. 27 patients were followed up(10-36 months).8 cases died of PCa,with a mean survival of 31 months.5 cases died of other diseases. After treatment, PSA levels decreased to ( 10.2 ± 6.7) μg/L. The average residual urinary volume (RU) decreased to (39.7 ± 13.9) ml, and the average IPSS was (8.7 ± 1.6 ). Compared with those of preoperation, the differences were statistically significant ( P < 0.05 ). Conelnsion TUVRP is a reliable treatment for prostate cancer with bladder outlet obstruction.

Aim To explore the effect of 4-amino-2-trifluoromethyl-phenyl retinate(ATPR)on proliferation,differentiation activity in K562 cell line,and to research the mechanisms.Methods Cell proliferation was assessed by MTT assay.Cell differentiation index was analyzed by NBT reduction test.Morphologic changes were observed by Wright's staining in the light microscope. Cell cycle was determined by FCM.The mRNA expression of Cyclin D1,Cyclin E,CDK2,CDK4,CDK6,P21cip1,P27kip1,P57kip2,PCNA mRNA were detected by RT-PCR.While the protein expression of cyclin D1 and CDK4 was detected by Western blot.Results The growth of K562 cells was inhibited in a dose-dependent manner.NBT reduction test indicated that the ATPR could induce differentiation of K562 cells and increase the positive cell ratio.Morphologic changes were observed after Wright's staining using inverted phase contrast microscope.The proportion of cells in G0/G1 phase increased while S phase cells decreased.Cell cycle progression was blocked in the G1 phase.The expression of Cyclin E,cyclin D1,CDK2,CDK4,CDK6 mRNA decreased,while PCNA,P21 cip1,P27 kip1 change was not obvious,but P57 (kip2) mRNA expression was increased.Cyclin D1 and CDK4 protein expressions were reduced as well.Conclusions ATPR inhibits the growth of K562 cells and induces differentiation.P57 kip2 plays a key role in differentiation.Moreover,high level of P57kip2 is regulated via inhibiting its degradation through reducing proteasome-dependent proteolysis,and ATPR plays a role in cell cycle arrest.
