Objective To investigate the effects of Xinshang Xuduan Decoction(XXD, mainly composed of Rhizoma Drynariae, Radix Dipsaci, and Eupolyphaga seu Steleophaga) on the proliferation and differentiation of rat osteoblasts and bone morphogenetic protein 2(BMP-2)expression in the osteoblasts . Methods The animal serum containing XXD was prepared by serum pharmacological method and then was mixed together with α-MEM for the cell culture. Osteoblasts were isolated from the skull bone of SD neonatal rats by collagenase digestion and were identified by alkaline phosphatase(ALP) staining and alizarin red staining. The third and fourth generations of osteoblasts were treated with XXD at the volume fraction of 5%, 10%, 20% for 24, 48 , 72 hours respectively, and then the proliferation of the cells was evaluated by Cell Counting Kit-8(CCK-8). In the other test, osteoblasts were cultured with blank control serum, and 10% serum containing XXD, Radix Dipsaci, and Rhizoma Drynariae, respectively, and then the ALP activity was examined by using ALP assay kit and the expression of BMP-2 was investigated by enzyme-linked immunosorbent assay(ELISA). Results XXD had a dose- and time-dependent effect on the proliferation of rat osteoblasts in a suitable volume fraction range from 5% to 20%, and the effect of XXD at 10% was the best. Compared with the blank control serum group, ALP activity was increased in the cells treated with 10% serum containing XXD, Radix Dipsaci, and Rhizoma Drynariae(P<0.01). On culturing day 7, the expression of BMP-2 was increased in 10% XXD group and Rhizoma Drynariae group(P<0.05). Conclusion XXD can increase the ALP activity and BMP-2 expression in the osteoblasts in vitro, so does the single herb of Rhizoma Drynariae. And their therapeutic mechanism in promoting the healing of fractures may be related with the enhancement of osteogenesis of osteoblasts.

BACKGROUND:The effect of body mass index (BMI) on the outcomes ofin vitrofertilization (IVF) is controversial. Some scholars suggested that the higher BMI, the lower rate of pregnancy, and the higher rate of abortion. However, some others got the different results. To data, the effects of BMI on the pregnancy outcomes in females at different ages are rarely reported.
OBJECTIVE:To explore the effect of BMI on the pregnancy outcomes of IVF for infertile women atdifferent ages.
METHODS:A total of 902 cycles undergoing IVF were divided into two groups according to the age:≤ or> 35 years old groups. The patients in each group were then divided into four subgroups according to BMI: low weight, normal weight, excess weight, and obesity subgroups, respectively.
RESULTS AND CONCLUSION: With increasing BMI, the average dosage of gonadotropins was increased gradualy in two both of age groups (P < 0.05). In the≤ 35 years old, the levels of estrogens on the day of injecting human chorionic gonadotropin was significantly lower in obesity group than the other subgroups (P < 0.05); the rates of empty folicle in excess weight and obesity subgroups were significantly higher than that in normal weight subgroup (P < 0.008 23). The fertilization rate and clinical pregnancy rate of in obesity subgroup were significantly lower than those in the other subgroups (P < 0.05). In the > 35 years old group, the empty folicle rate in obesity subgroup was significantly higher than that in normal weight subgroup (P < 0.008 23). Fertilization rate in excess weight and obesity subgroups was significantly lower than that in the normal weight subgroup (P< 0.008 23). There were no significant differences in cleavage rate, cycle cancelation rate, implantation rate, biochemical pregnancy rate and abortion rate between four subgroups (P> 0.05). These findings suggest that in the females at the younger age, BMI not only affects the quality of folicles and fertilization rate; but with increasing BMI, clinical pregnancy rate is decreased obviously. However in the females at the older age, BMI only affects the folicular quality, embryo quality and fertilization rates; there are no significant differences in the outcomes of pregnancy in the four subgroups. BMI have effects on pregnancy outcomes of IVF, and the effects are much greater in the younger female group.

microRNAs ( miRNAs) are a family of short non-cod-ing RNAs that regulate the expression of target genes by binding to complementary regions. The miRNAs expression is readily al-tered by drugs, carcinogens, hormones, stress or diseases, and that might lead to changes in the drug metabolism, pharmacoki-netics or potency. Moreover, the evaluation of drug metabolic enzyme-related miRNAs would provide useful information for per-sonalized medicine. This review describes the current knowledge on the post-transcription regulation of drug metabolic enzymes by miRNAs.

OBJECTIVE:To provide reference for perioperative rational prophylactic application of antibacterials in type Ⅰ in-cision operation. METHODS:4 201 patients underwent type Ⅰ incision operation were collected from a class A grade three hospi-tal during Mar. 2013-Feb. 2015. The perioperative prophylactic application of antibacterials in type Ⅰ incision operation were ana-lyzed statistically. RESULTS:Of 4 201 patients underwent type Ⅰ incision operation,there were 2 399 cases of prophylactic appli-cation of antibiotics(accounting for 57.10%). Cephalosporins andβ-lactam/β-lactamase inhibitor were the main classes of antibacte-rials for preventive use,accounting for 45.60%and 19.76%,respectively. The frequency of using cefazolin,ceftriaxone and amoxi-cillin-clavulanic acid ranked the top 3 places, among which there was 823 cases of unsuitable prophylactic medication time (34.31%),and 855 cases of prophylactic medication time >48 h(accounting for 35.64%). CONCLUSIONS:There still is unrea-sonable perioperative prophylactic application of antibacterials in type Ⅰ incision operation in this hospital. It is necessary to strengthen the supervision of antibacterials and conduct regular rational antibacterials use seminars in order to promote rational use of antibacterials.

Irritable bowel syndrome( IBS)is a commonly seen chronic functional bowel disease,the prevalence showed a rising trend in recent year in China. At present,the etiology and pathogenesis of IBS have not yet been fully elucidated,and may be related to intestinal gas. Intestinal gas is usually composed of 59% N2 ,21% H2 ,9% CO2 ,7%methane(CH4 )and 4% O2 ,in which H2 and CH4 are produced only by intestinal bacteria metabolism. IBS patients usually manifested as having abdominal distension and symptoms of flatulence,suggesting the occurrence of accumulation of intestinal gas. In recent years,the relationship between symptoms of IBS and intestinal gas has attracted much attention. This article reviewed the progress in study on symptoms of IBS and intestinal gas.

OBJECTIVETo investigate the effect of midazolam on human ether-a-go-go (hERG) K+ channels exogenously expressed in human embryonic kidney cells (HEK-293) and the underlying molecular mechanisms.

METHODSWhole-cell patch clamp technique was used to record WT, Y652A and F656C hERG K+ current expressed in HEK-293 cells.

RESULTSMidazolam inhibited hERG K+ current in a concentration-dependent manner, the half-maximum block concentrations (IC50) values were (1.31 ± 0.32) µmol/L. The half-activation voltage (V1/2) were (2.32 ± 0.38) mV for the control and (-1.96 ± 0.83) mV for 1.0 µmol/L midazolam. The half-inactivation voltage (V1/2) was slightly shifted towards negative voltages from (-49.25 ± 0.69) mV in control to (-57.53 ± 0.53) mV after 1.0 µmol/L midazolam (P < 0.05). Mutations in drug-binding sites (Y652A or F656C) of the hERG channel significantly attenuated the hERG current blockade by midazolam.

CONCLUSIONMidazolam can block hERG K+ channel and cause the speed of inactivation faster. Mutations in the drug-binding sites (Y652 or F656) of the hERG channel were found to attenuate hERG current blockage by midazolam.

BACKGROUND: Smooth muscle cells (SMCs) proliferation and transmigration and platelet activation cause thrombogenesis and lead to grafted vessel restenosis. Nitric oxide (NO) can inhibit the above-mentioned biological responses, but whether endothelial nitric oxide synthase (eNOS) gene transfection can inhibit the neointimal hyperplasia in graft seeded with SMCs remains uncertain.OBJECTIVE: This study was designed to further investigate the effect of eNOS gene transfection on neointimal hyperplasia in the grafts seeded with SMCs.DESIGN, TIME AND SETTING: This study, a repeated observation and measurement experiment, was performed at the Central Laboratory and Laboratory of Molecular Biology of Xi'an Jiaotong University Medical College from April 2006 to May 2007.MATERIALS: One 1-month-old New Zealand rabbit was used to acquire SMCs. Another 18 adult New Zealand rabbits were randomly divided into 3 groups (n=6).In normal control group,the vessel graft with no SMCs were transplanted; In SMC/lacZ group, the vessel grafts with SMCs transfected with lacZ were transplanted;In SMC/eNOS group,the vessel grafts with SMCs seeded with eNOS were transplanted.METHODS: Rabbit SMCs were transduced with pseudotyped retroviral vectors, Murine leukemia virus/vesicular stomatitis virus G glycoprotein, carrying genes coding for eNOS or lacZ gene. The SMCs then were seeded on the vessel grafts and implanted into the rabbit abdominal aorta using vessel bypass transplantation.MAIN OUTCOME MEASURES: Nitric oxide (NO) content in the supernatant of cells transfected with eNOS and lacZ gene was detected by citrulline method. The grafts were stained with X-gal to visualize the seeded cells: the seeded SMCs were stained blue,while eNOS were stained red. The thickness of the neointima on a graft was measured with a microscope.RESULTS: Eighteen rabbits were all included in the final analysis. NO content in the SMC/eNOS group was significantly higher than that in the normal control group (P<0.05). The SMCs transfected with lacZ gene showed blue after X-gal staining under the inverted microscope. Thirty days after implantation, there was no difference in neointimal thickness between normal grafts and grafts seeded with eNOS or lacZ transduced SMCs (P>0.05).100 days after implantation,the neointimal thickness on grafts seeded with eNOS transduced SMCs was similar to that of unseeded grafts (P>0.05 ), but was significantly thinner than that on grafts seeded with SMCs transduced with only lacZ gene (P<0.05).CONCLUSION: eNOS gene transfection inhibits nenintimal hyperplasia in the vessel graft seeded with SMCs.
