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 study the relationship between the liver sinusoidal pathological changes and portal hypertension during the dimethylnitrosamine (DMN) induced liver fibrosis in rats. Methods The rat liver fibrosis model was established by peritoneal injection of DMN (at a dose of 10 mg/kg, 3 times a week, for 4 weeks) in 40 male Wister mice. In the control group of 24 healthy mice, saline solution was injected peritoneally. The dynamic changes of liver fibrosis were observed at different time points (1, 2, 3 day, 1, 2, 4, 6 and 8 week). The pressure of portal vein (Ppv) was directly measured by the intubation of mesentery anterior vein in 5 mice of the model and 3 of the control. The expressions of type Ⅳ collagen (Col Ⅳ), laminin (LM) and type Ⅰ collagen (Col Ⅰ) were detected by immunohistochemistry. Hepatic ultrastructure was observed by electron microscopy. Results Positive expression of Col Ⅳ was observed in the normal liver sinusoidal walls. The various intensities of positive staining of Col Ⅳ were observed in the liver sinusoidal walls of the fibrosis model. Positive expressions of LM and Col Ⅰ increased, and the strongest positive staining displayed in the 4 week model rats. Meanwhile, the fenestrae in the sinusoidal endothelial cells (SECs) were lost and the basal membrane was formed. There was a remarkable positive correlation between the Ppv and the expressions of LM in the DMN induced rat fibrosis( P

Objective To evaluate the efficacy and safety of two kinds of hydrotalcite, Weidimei and Talcid, in treating bile reflux gastritis. Methods Thirty patients with bile reflux gastritis confirmed by endoscopy were equally divided into experimental group (Weidimei) and control group (Talcid). The patients were given Weidimei or Talcid both at the dose of 1.0 g 3 times a day for 4 weeks, respectively. The severity of the symptoms including abdominal pain, regurgitation, nausea and vomiting of bile were investigated before and after the treatment. Twenty four hour bile in stomach was monitored. Results The severity of all symptoms greatly decreased after the treatment in two groups ( P

Objective:To investigate the eating disorder and mood among students of a female university in Beijing.Methods:352 female students from a same-sex college in Beijing,between the age of 17-25 years were in- vestigated by Eating Disorder Inventory(EDI)and Profile of Mood States-Short Form(POMS-SF).Their weight and height were also collected for calculating for their body mass index(BMI).Results:Female university students showed serious tendency of eating disorder.The negative attitudes to body and body satisfaction were serious among normal BMI female university students.The behaviors and attitudes to eating disorders among the students of fresh-woman and senior were significantly higher than other grades(x~2=17.94,P

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.
