To investigate the influence of the difference enhancers on the transport mechanism of chlorogenic acid (CGA) across Caco-2 cells model, a RP-HPLC method was adopted to detect the concentrations of CGA. At the concentrations of 20 to 80 microg x mL(-1), the difference of absorption rate constants (K(a)) was not statistically significant. At the concentrations of 40 and 20 microg x mL(-1), the ratios of apparent permeability coefficients (P(app)) of the apical to basolateral and the basolateral to apical were 1.14 and 1.18, respectively. With the effect of enhancers K(a) and P(app) increased, the absorption half-life (T1/2) decreased. CGA passed through the Caco-2 cell membrane mainly by passive transport. It showed that monocarboxylic acid transporter (MCT) could be involved in the across membrane transport process of CGA. Borneol had no effect on the cell membrane transport processes. The order of increasing absorption of CGA caused by the enhancers was sodium lauryl sulphate > sodium taurocholate > carbomer.

ObjectiveTo observe the relationship between astrocytes and neurons in rat's medulla oblongata after exposed to 8Hz, 90dB/130dB infrasound for different times. MethodsRats were exposed to 8Hz, 90dB/130dB infrasound for 2 hours per day.At the 1st,7th,12th,21th and 28th day, the expression of glial fibrillary acidic protein (GFAP) and Fos in medulla oblongata were detected using double-labling immunohistochemical method.Results GFAP-positive astrocytes and Fos-positive neurons were increased after exposure for one time. They showed similar topographic localization and formed close relationship. Their number increased as the exposure times increasing, and decreased gradually after 14 days. The reaction of 130dB group was stronger than that of 90dB group.Conclusions 8Hz, 90dB/130dB infrasound can activate both astrocytes and neurons in rats' medulla oblongata which might participate and regulate the response to infrasound.

Aim To explore the effects of anti-HER-2 chimeric antibody chA 21 on proliferation and apoptosis of SKBR3 cells.Methods MTT colorometric assay,HE staining,transmission electron microscopy,flow cytometry,and TUNEL were used to study the proliferation inhibition and apoptosis induction of SKBR3 cells by chA 21 in vitro.Results Proliferative inhibition rates and apoptotic index of SKBR3 cells were increased in a dose and time dependent manner after exposure to chA21(0.2～5.4 mg?L~(-1)).Conclusion chA 21 could remarkably inhibit proliferation of SKBR3 cells in vitro and apoptosis induction may be one of its main mechanisms.

Objective To study the influence of different body serum iron levels on follicle stimulating hormone (FSH),luteinizing hormone (LH) and uterine ovarian index,and explore the body serum iron level effects on female mice sexual maturity further.Methods 36 three weeks C57BL/6J female mice were randomly divided into the normal control group,strengthen-iron 1 group and strengthen-iron 2 group,12 cases in each group.The normal control group with normal diet(310mgFe/kg),strengthen-iron 1 group and strengthen-iron 2 group were given high -iron diets(respectively with 465mgFe/kg and 620mgFe/kg) after born 3 weeks.each group body,uterus and ovary mass after 2 weeks were checked;colorimetric method was used to detect the serum iron level;the serum follicle stimulating hormone (FSH) and luteinizing hormone(LH) were detected by chemiluminescent immunoassay.Results The body of mice serum iron levels,uterine ovarian index (uterine ovarian wet mass/body mass) and follicle stimulating hormone(FSH) level of strengthen-iron 1 group and strengthen-iron 2 group were higher than those of normal control group (F =9.11,11.11,7.09,all P ＜ 0.01).Luteinizing hormone (LH) level of the strengthen-iron group was higher than those of normal control group (F =3.89,P ＜ 0.05).Conclusion Uterine ovarian index,follicle stimulating hormone level and luteinizing hormone level were affected with increased serum iron level;It suggests that the increasing serum iron level can cause female mice sexual maturity in advance.

Objective To assess right ventricular (RV) regional and global volume and systolic function in patients with right coronary artery disease by real time three-dimensional echocardiography(RT-3DE).Methods RT-3DE images were acquired in 20 normal controls (Group A),30 patients with right coronary artery stenosis(Group B) and 10 patients with RV myocardial infarction(Group C).Volumetric RT-3DE images were analyzed by use of TomTec software,which provided regional (inflow,body and outflow) and global end diastolic volume(EDV),end systolic volume(ESV),stroke volume(SV) and ejection fraction(EF).RT-3DE quantitative data were analyzed to test repeatability.Results Compared with group A and group B,EDV and ESV of body and global were larger in group C;ESV of inflow and outflow were larger (P ＜0.05).EDV of group C was larger than group B(P ＜0.05).Compared with group A and group B,the EF of inflow,outflow and global in group C were lower(P ＜0.05).The EF of body in group C were lower than group B(P ＜0.05).There was no significant difference in regional and global volume and EF between group A and group B(P ＞0.05).The intra-observer and inter-observer's variability was low and consistency was high.Conclusions In patients with RV myocardial infarction,RV regional and global volumes were enlarged and systolic function was impaired.Evaluating right ventricular regional and global volume and function in patients with right coronary artery disease by RT-3DE has high repeatability.

OBJECTIVETo investigate the effects of the plasma containing Qianlongtong Capsule (QLT)-containing plasma on the expression of the Smad4 gene in prostate stromal cells in vitro and provide some experimental evidence for the treatment of benign prostatic hyperplasia (BPH) with Chinese medicinal compound.

METHODSFifteen cases of BPH were equally randomized to three groups to be treated with QLT at a high dose (6 capsules once), a medium dose (3 capsules once), and a low dose (1.5 capsules once), tid, for 7 days consecutively. QLT-containing plasma was collected from the patients. Prostate stromal cells were identified by immunofluorescence when they became monolayered and cultured in the QLT-containing plasma for 24 hours, followed by detection of the expression of the Smad4 gene by real-time quantitative PCR and that of the Smad4 protein by Western blot.

RESULTSAfter treatment with the QLT-containing plasma, the expression of the Smad4 gene in the stromal cells was significantly increased in a dose-dependent manner as compared with the blank control and no-QLT groups (P < 0.01). The expression of the Smad4 protein was also markedly elevated after treatment. The differences were statistically significant between the blank control and medium-dose groups (P < 0.01), low-dose and medium-dose groups (P < 0.05), and high-dose and the other groups (P < 0.01), but not between the blank control and low-dose groups (P > 0.05).

CONCLUSIONQLT-containing plasma could inhibit the proliferation and improve the apoptotic index of prostate stromal cells in vitro, which was related to the elevation of the mRNA and protein expressions of Smad4.

Objective To study the anti-tumor effect of anti-HER-2 engineering antibodies chA21 and Herceptin on nude mice xenografts of human ovarian cancer SKOV3 cells and explore its mechanism.Methods An animal model with human ovarian cancer SKOV3 cells involved in nude mice was established and the mice were randomized into 3 groups: normal saline(NS),chA21 and Herceptin.The mice were respectively administrated with Herceptin(30mg/kg) and chA21(30mg/kg) via caudal vein injection twice a week for consecutive 6 weeks,and then were killed after 44 days adminstration of the drugs.The volumes of the xenografts were measured twice a week.The tumor weight and inhibition ratio were measured after mice were killed.Ki67 and NF?B expression in the three groups was quantificationally analyzed by immunohistochemistry on tissue microarray sections combined with a micro-image analysing system.Results The growth of xenografts of human ovarian cancer SKOV3 cells in nude mice was significantly inhibited by either Herceptin or chA21. Both Ki-67 labeling indices and NF?B levels in chA21 and Herceptin groups were lower than those in the control(P
