BACKGROUND:Excessive apoptosis and decreased infiltration of cytotrophoblasts are essential causes for hypertension in pregnancy. Human placenta-derived mesenchymal stem cels contribute to damage repair, which has been shown in many studies, and moreover, human placenta-derived mesenchymal stem cels have a certain endocrine function and can act on the other tissues in an autocrine or paracrine manner. Therefore, we attempt to explore whether the human placenta-derived mesenchymal stem cel can repair damaged cytotrophoblasts, and then to gestational hypertension.
METHODS/DESIGN:This is a randomized controled cytological experiment. Human placenta-derived mesenchymal stem cel culture medium is colected and filtrated as human placenta-derived mesenchymal stem cel conditioned medium. Human cytotrophoblasts, JEG-3 cels, are cultured and randomized into three groups:15% normal pregnant serum is added in control group; 15% serum from severe pre-eclampsia patients is added in gestational hypertension model group; and in condition medium group, 15% serum from severe pre-eclampsia patients is added for 24 hours of culture, and then human placenta-derived mesenchymal stem cel conditioned medium containing 15% serum from severe pre-eclampsia patients is used instead. Flow cytometry is used to detect cel apoptosis rate.
DISCUSSION: This study wil help to find the feasibility of cel transplantation for gestational hypertension by exploring the effect of human placenta-derived mesenchymal stem cels on cytotrophoblasts function in gestational hypertension.
ETHICAL APPROVAL: The protocol is approved by the Ethics Committee of Shenyang Central Hospital of Shenyang Medical University. Informed consent is obtained from normal and pre-eclampsia women in pregnancy.

Brain-derived neurotrophic factor (BDNF)is both a neurotrophic substance and a neurotransmitter.BDNF and its receptors are highly expressed in enteric nervous system,intestinal mucosal epithelium and intestinal muscularis, which play an important role in regulating intestinal sensitivity and motility.This article reviewed the expression and role of BDNF in intestinal tract.

The PDB culture medium was selected to ferment the endophyte strain, and the secondary metabolites of endophytic fungi Penicillium polonicum were studied. Combined application of Sephadex LH-20, ODS and HPLC chromatographies over the ethyl acetate extract of the fermented culture led to the isolation of 6 compounds. By spectral methods, the structures were elucidated as [3, 5-dihydroxy-2-(7-hydroxy-octanoyl)]-ethylphenylacetate (1), (3, 5-dihydroxy-2- octanoyl)-ethyl phenylacetate (2), (5, 7-di- hydroxy-9-heptyl)-isobenzo pyran-3-one (3), 3-(hydroxymethyl) 4-(1E)-1- propen-1-yl-(1R, 2S, 5R, 6S)-7-oxabicyclo [4.1.0] hept-3-ene-2, 5-diol (4), (E)-2-methoxy-3-(prop-1-enyl) phenol (5) and p-hydroxylphenylethanol (6).

OBJECTIVETo explore the intervention of Fagopyrum cymosum (Trev.) Meisn alcohol extract (FAE) on defecation function and motor functions of isolated colons of diarrhea-predominant irritable bowel syndrome (D-IBS) rats and to study its underlying mechanism.
METHODSThe D-IBS rat model was established by neonatal pups maternal separation (NMS) combined with intracolonic infusion of acetic acid (AA). Adult IBS rats were randomly divided into the pre-intervention control group (n = 10, with no gastrogavage), the normal saline control group (n = 10, administered with normal saline by gastrogavage), the pre-treatment model group (n = 8,with no gastrogavage),the normal saline model group (n = 8, administered with normal saline by gastrogavage), the low dose FAE group (n = 8, administered with 6 g/kg FAE by gastrogavage), the high dose FAE group (n = 8, administered with 24 g/kg FAE by gastrogavage), and the Pinaverium Bromide group (n = 8, administered with 0.02 g/kg Pinaverium Bromide by gastrogavage). All medication was performed once daily for 2 weeks. The abdominal withdrawal reflex (AWR) was employed to evaluate the visceral hypersensitivity; their loose and watery stool grade was assessed by Bristol scores for stool consistency; and their fresh feces weight was calculated. In vitro effect of different concentrations of FAE and Pinaverium Bromide (0.02 μg/mL) on spontaneous contraction and spasmodic contraction induced by acetylcholine (Ach) in rats' isolated colon were observed and the influence on the intestinal calcium channel was evaluated.
RESULTSCompared with the pre-intervention control group, the pain pressure threshold and the maximum tolerance pressure decreased significantly in the pre-intervention model group (P < 0.05), and the loose and watery stool grade and fresh feces weight increased drastically (P < 0.01). Compared with the normal saline control group, the pain pressure threshold and the maximum tolerance pressure decreased significantly in the normal saline model group (P < 0.05), and the loose and watery stool grade and fresh feces weight increased markedly (P < 0.01). Compared with the normal saline model group, the pain pressure threshold of 24 g/kg FAE and Pinaverium Bromide group significantly increased (P < 0.05). The loose and watery stool grade and fresh feces weight decreased obviously in the low dose FAE group, the high dose FAE group, and the Pinaverium Bromide group (P < 0.05). FAE (30, 100, 300, 1,000, and 3,000 μg/mL) and Pinaverium Bromide could significantly inhibit spontaneous contraction of isolated intestines (P < 0.05, P < 0.01), and FAE (30, 100, and 300 x 10(-6) g/mL) could remarkably inhibit their spasmodic contraction and contractile tension induced by Ach and Ca2+ respectively (P < 0.05, P < 0.01) in a concentration-dependent manner. Pinaverium Bromide also could significantly inhibit Ach and Ca2+ induced contraction.
CONCLUSIONEffective components of FAE improved the defecation function and inhibited enterospasm induced intestinal hyperactivity in IBS model rats via antagonizing calcium channel competitively and inhibiting colonic motility dose-dependently.
