OBJECTIVETo explore the efficacy and safety of prostatic arterial embolization (PAE) in the treatment of benign prostatic hyperplasia ( BPH) in high-risk aged males.
METHODSWe retrospectively analyzed the clinical data about 21 high-risk BPH patients aged 77-91 (mean 80) years treated by PAE.
RESULTSPAE was successfully performed in all the 21 patients, with the operation time of 90-120 min. At 2 weeks, 3 months, 6 months, and 12 months after surgery, the International Prostate Symptom Scores (IPSS) were 18.3 ± 3.1, 9.8 ± 2.7, 9.4 ± 2.5, and 10.1 ± 2.2, the quality of life scores ( QOL) were 4.6 ± 1.4, 4.3 ± 1.2, 4.6 ± 1.1, and 4.9 ± 0.6, the maximum urinary flow rates ( Qmax) were (12.5 ± 2.5), (15.8 ± 2.4), (16.6 ± 2.2), and (16.3 ± 1.8) ml/s, and the postvoid residual urine volumes (PVR) were (35.0 ± 3.4), (13.0 ± 3.3), (10.0 ± 3.0), and (8.0 ± 2.5) ml, respectively, markedly improved as compared with the baseline (IPSS: 24.5 ± 3.7, QOL: 5.7 ± 1.6, Qmax: [8.3 ± 2.1] ml/s, and PVR: [98.0 ± 11.0] ml), with statistically significant differences in IPSS, QOL, Qmax, and PVR (all P < 0.05). The maximal velocity of blood flow in the prostate was obviously decreased and the prostate volumes were (74.4 ± 4.8), (42.5 ± 4.4), (38.3 ± 4.0), and (36.7 ± 3.5) cm3 at 2 weeks, 3 months, 6 months, and 12 months, respectively, also significantly reduced in comparison with (84.3 ± 5.4) cm3 preoperatively (all P < 0.05).
CONCLUSIONPAE is a safe and effective option for the treatment of BPH in high-risk aged males.

Objective To evaluate the value of ERCP in treating hepatocellular carcinoma complicated with tumor thrombi in bile duct.Methods To analyze retrospectively the results of 15 cases of hepatocellular carcinoma with tumor thrombi in the bile duct including ERBD 8 cases and ENBD 7cases,EMBE after ENBD 4 cases, EST with clearance of tumor thrombi and cytological brush 12 cases, ERCP conjugated with other compositive treatments 9 cases.Results The common feature of cholangiography is filling defect in the bile duct as the so called "tennis bat" sign and "flocculation" sign, 13 cases have got drainage successfully after ERCP with the effective rate 86 7%, Satisfactory results were obtained in patients received ERCP conjugated with other compositive treatments.Conclusion ERCP is very important treatment of hepatocellular carcinoma with tumor thrombi in the bile duct; the "tennis bat" sign and "flocculation" sign were the very important evidences of tumor thrombi in the bile duct. If combined with other compositive treatment such as surgery and TAE, ERCP is very effective treatment for the releasing symptoms, improving living quality and prolonging life span in these patients, even in some patients radical cure could be obtained.

Objective To establish the computer controlled operant behavior test system for rats,and to explore the effects of prenatal exposure to low level methylmercury on the ability of learning and memory in rats Methods The Wistar rats were perorally perfused by 0,0.01,0.05,2.00 mg/(kg?d) methylmercury chloride(MMC) during the period from the 6th day to the 9th day after conception respectively.In every dose group,8 offspring aged 10 weeks were randomly selected to be tested by operant behavior test system.The operant performance was measured in automated nocturnal 15 hour session(16∶00~7∶00).The trial pragram Differential Reinforcement of High (DRH) rate and of low (DRL) rate was carried out by a double blind method.The DRH tests required observed animals to press levers frequently,while the DRL test required the subjects to respect a blocking interval after a reinforcement for pressing lever again. Results The performances scores of 3 exposure groups at doses of 0.01,0.05 and 2.00 mg/(kg?d) methylmercury were significantly lower than that of the control group( P

Objective:To explore the possibility of inducing cell mediated immune response with HSP70 antigenic peptide complex in vitro.Methods:HSP70 peptide complex was reconstituted in vitro.Granulocyte/macrophage colony stimulating factors and interleukin 4 were used to cultivate DC from peripheral blood of HLA A2 positive healthy donors.HSP70,HSP70 peptide complex or peptide was used to activate the DC individually,which will initiate homogenize T lymphocyte to form cytotoxic T lymphocyte(CTL).The cytotxicity of the CTL was detected by MTT assay.Results:It was found that peptide specific CD8 + CTL responses were readily elicited by HSP70 peptide complex or peptide.The CTL response primed by HSP70 peptide complex was more potene than peptide alone.Conclusion:The results suggest that HSP70 peptide complex is immunogenic and HSP70 can lead to great efficient CTL response,antigenic peptides and HSP70 complex may be used as peptide vaccines for cancer immunotherapy.

Purpose:To evaluate the therapeutic effect of paclitaxel and platinum containing chemotherapy (cisplatin or carboplatin) in women with epithelial ovarian cancer.Methods:We assigned 16 cases with advanced epithelial ovarian cancer after initial surgery to receive paclitaxel and cisplatin or carboplatin. Pcalitaxel (135 mg/m 2,over a period of 10 hours ) was administered iv once every 3 to 4 weeks, 24 control cases were treated with "CAP" or "CVP" regimen. Results:The overall median survival was significantly longer in the paclitaxel platinum group than in the cisplatin cyclophosphamide group (median, 35 vs. 22.5 months, P

Objective:To explore the possibly mechanisms of inducing allogeneic chimerism and prolonging allografts survival in recipients by immature dendritic cells (imDCs) Methods:Bone marrow cells (BMCs) derived from donor (C57BL/6) were used to generate imDCs The splenocytes of recipients were pretreated by inactivated imDCs in vitro, or the recipients (Balb/C) were injected of inactivated imDCs via vein in vivo Then collected the splenocytes mixed with the inactivated splenocytes from donor to detect the responsiveness Mixed lymphocyte reaction was also used to evaluate the reactivity of the chimerism mice to the donor splenocytes At the same time the diversion of Th1/Th2 paradigm was studied by semi quantitative RT PCR Results:The splenocytes conditioned with imDCs pretreatment expressed hypo responsiveness to the donor stimulation, and the immunized mice also proliferated less degree compared with the naive mice The hyporeactivity was evidently seen within 72 hours after stimulation by donor splenocytes There was significant difference between them The chimerism mice showed unresponsiveness to donor antigens, while reactivity to the third party antigens was retained The result of RT PCR suggested, to some extent, there was a diversion of Th1/Th2 paradigm in the establishment of chimerism in the model Conclusion:The putative mechanism of immature dendritic cells inducing the generation of allogeneic chimerism may based on the hypo responsiveness produced by imDCs, and there may also exist some kinds of diversion of Th1/Th2 paradigm

Objective To investigate the effect of a self made liposome perfluocarbon ultrasound contrast agent in enhancing grey scale imaging of normal kidney.Methods The kidneys of 10 normal rabbits were imaged with second harmonic imaging before and after intravenous injection of the liposome contrast agent at a dose of 0.01 ml/kg. The subjective scores and video intensities were used to evaluate contrast effects. Results The renal cortex,medulla and sinus grey scale imaging were greatly enhanced after injection, and the notable enhancement time of renal cortex,medulla and sinus could last for 52 min,2 min 20 s,1 min 40 s,respectively. Conclusions The self made liposome perfluocarbon contrast agent can significantly long time enhance the grey scale of the kidney.
