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.

With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

OBJECTIVETo observe features of Icariin in promoting osteogenic differentiation of SD rat bone marrow mesenchymal stem cells (BMSCs) in vitro.

METHODS(1) SD rats' BMSCs were isolated and purified by mechanically isolated and cultured by whole bone marrow adherent method. Effects of various concentrations Icariin on serum activities of alkaline phosphatase (ALP) were detected using amino antipyrine phenol determination method at day 3, 6, 9, 12, 15, 18, and 21. Calcium nodes of each groups were detected using alizarin red staining. Roles of various concentrations Icariin in promoting osteogenic differentiation of BMSCs were observed. (2) BMSCs were divided into the blank control group, the osteogenic induced group, and the Icariin group (0.5 microg/mL). ALP activities were detected at day 7, 14, and 21 of culture. Meanwhile, ALP positive staining rate and calcium nodes were detected at day 14 and 21 respectively. Additionally, mRNA expressions of Runt-related transcription factor-2 (Runx2) and Osteocalcin were detected at day 7, 14, and 21 by real-time fluorescent quantitative PCR.

RESULTS(1) 0.05-5.0 microg/mL Icariin could significantly elevate serum ALP activities. Of them, 0.2-2.0 microg/mL Icariin significantly increased calcium nodes numbers (P < 0.01). (2) When Icariin promoted osteogenic differentiation of BMSCs, Runx2 mRNA expression levels and ALP activities increased earlier and then decreased, while osteocalcin mRNA expression levels continued to increase (P < 0.01). Compared with the osteogenic induced group, ALP activities and ALP positive staining rate were both elevated after 14 days of Icariin treatment in the Icariin group (P < 0.05, P < 0.01).

CONCLUSIONSIcariin could promote the differentiation of BMSCs to osteoblasts by up-regulating Runx2 mRNA expression levels. It also could promote the mineralization by increasing ALP secretion and Osteocalcin mRNA expression levels, thereby promoting mature of newly generated osteoblasts.

To study the effect of Fuzheng Huayu recipe (FZHY) on five types of isozymes of cytochrome P450 (CYP450) of normal and liver fibrosis rats by using the cocktail probe method. Dimethylnitrosamine ( DMN) was injected to induce the liver fibrosis model. After the tail vein injection with Cocktail probe solutions prepared with five CYP450s probe substrates (phenacetin-CYP1A2, omeprazole-CYP2C9, tolbutamide-CYP2C19, dextromethorphan-CYP2D6, midazolam-CYP3A4), the plasma concentrations of the five probe substrates were determined by LC-MS/MS, and the pharmacokinetic parameters were calculated by PK solutions 2. After the oral administration with FZHY, normal rats given phenacetin, omeprazole, tolbutamide and dextromethorphan showed increase in AUC(0-t) and decrease in CL to varying degrees, indicating that FZHY obviously inhibited the activities of CYP1A2, CYP2C9, CYP2C19 and CYP2D6 in normal rats, but with no obvious effect on the activity of CYP3A4. After the oral administration with FZHY, liver fibrosis rats treated with CYP2C9 showed the significant increase in AUC(0-t) and significant decrease in Vd, hut with no obvious changes in the pharmacokinetic parameters of other four types of prove substances, suggesting that FZHY could significantly inhibit the activity of CYP2C9 in rats but had no effect on the activities of CYP1A2, CYP2C19, CYP2D6 and CYP3A4. The changes in the activity of CYP450 isozymes in liver fibrosis rats may be the reason for FZHY's different effects on CYP450 isozymes in normal and liver fibrosis rats.
