Hepatocyte growth factor(HGF) is a mesenchyme-derived pleiotropic factor which regulates cell growth,cell motility,and morphogenesis of various types of cells,and is thus considered a humoral mediator of epithelial-mesenchymal interactions responsible for angiogenesis,apoptosis and oxidative stress,etc.This article reviewed the relationships between HGF and cardiovascular diseases.

Objective To measure the renal tissue texture or flexibility with virtual touch quantization (VTQ) and to tentatively examine its clinical application in patients with chronic kidney disease(CKD).Methods A total of 750 patients (1500 kidneys) were performed with VTQ,including 400 cases in the control group,and 350 cases in the CKD group.A conventional ultrasound examination (two-dimensional,color Doppler) were first taken,and then the shear wave velocity (Vs) was measured which reflected the textural elastic.Results In both groups the Vs was the highest in renal cortex with significant difference (P<0.05); renal cortical region Vs in CKD group was lower than those in control group (P<0.05),while Vs of renal medulla and renal sinus had no significant difference in the two groups.The severity of renal dysfunction was increased along with a Vs decrease of renal cortex.Conclusion VTQ is helpful to assess renal function of patients with CKD.

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.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.

METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.

RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.

CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

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.
