Objective To find out the features and causes of the complications of multiple system organs failure (MSOF) in pregnancy and increase the level of its prevention and treatment. Methods A retrospective study was carried out on 13 cases with the complication of MSOF in pregnancy admitted between Feb 1992~ Jun 1999. Results There were two or more organs or systems function failure in the pregnancy. Four cases induced by infection, 5 cases induced by heart diseases, 3 cases induced by pregnancy induced hypertension, 1 case induced by amniotic fluid embolism. 12 of 13 were cured.1 was died. Among them one infant was died. Conclusions During the treatment of pregnancy with multiple system organs failure, it is important to control the causes and inducements. It is forcible to terminate pregnancy in time and choose a best style of delivery. It is better to keep watch on saving multiple system organs function.

The study aims to screen the ability of the bacteria to metabolize ononin and assess the effect of ononin on the intestinal bacteria. Fresh human fecal sample was obtained from a healthy volunteer, diluted serially in sterile water and sixty-nine different bacterial colonies were picked out ultimately. UPLC-Q-TOF/MS with automated data analysis software (MetaboLynx) was applied to fast analysis of ononin metabolites. Furthermore, an E(max) precision microplate reader was employed to determine the growth situation of Enterococcous sp., Enterobacter sp., Lactobacilli sp., and Bifidobacteria sp. Results indicated that hydrogenation, demethylation, hydroxylation and deglycosylation were the major metabolic pathways of ononin by human intestinal bacteria in vitro. Ononin can inhibit the growth of pathogen such as Enterococcus sp., Enterobacter sp. and can promote the growth of probiotics such as Bifidobacteria sp. and Lactobacilli sp. This study suggested that intestinal bacteria have the metabolic effects of ononin and the biotransformation was completed by different bacteria. And ononin can affect the balance of intestinal flora and the degree of influence varies depending on the bacterial species and the concentration of ononin.

Naringin has been reported to possess a wild range of biological activities. However, the route and metabolites of naringin produced by intestinal bacteria are not well understood. In this paper, different bacteria were isolated from human feces and their abilities to convert naringin to different metabolites were studied. Ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) with automated data analysis software (MetaboLynx) was applied to fast analysis of naringin metabolites. Using MSE and mass defect filter techniques, three metabolites were detected and tentatively identified. The results indicated that acetylation, hydrolyzation and hydrolyzation with hydrogenation were the major metabolic pathways of naringin in vitro. Then, we studied the gene sequence of the 16S rRNA of the bacteria by extraction of genomic DNA of the strain, PCR amplification and clone of the 16S rRNA. The consequence proved that Enterococcus sp.30, Bacillus sp.46, Escherichia sp.54 and Escherichia sp.63 have the peculiar metabolism characteristic of naringin.

The changes of bioactive constituents were analyzed for Puhuang-Wulingzhi before and after compatibility and the antiplatelet and antithrombin activitives were evaluated in order to elucidate the scientific and reasonable of Puhuang-Wulingzhi compatibility. UPLC-QTOF-MA-Markerlynx, principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis were used for data analysis and tracking changes of chemical composition during the decocting process. In vitro platelet aggregation induced by ADP, thrombin time(TT) and prothrombin time (PT) were investigated for Puhuang-Wulingzhi before and after compatibility. The results showed that significant differences were found between the mixed decoction and codecoction of Wulingzhi and Puhuang. Five compounds changed obviously were identified as typhaneoside, naringenin, isorhamnetin-3-O-ruinoside, quercetin-3-O-neohesperidoside, kaempferol-3-O-neohesperidoside. The codecoction, comparing with the single decoction, was more significant in antiplatelet aggregation and could prolong thrombin time. In the same crude drug dose, the thrombin time (TT) elongation were greater. These data could provide references for elucidation of bioactive components for this herb pair.

Angelicae Sinensis Radix-Chuanxiong Rhizoma has the effects of nourishing and tonifying blood, activating blood and dissipating blood stasis, regulating menstruation and analgetic, which is commonly used Chinese medicine pair (CMP) in traditional Chinese medicine (TCM) clinic. It might be an independent formula, and is also usually used in many gynecological formulae and modern TCM prescriptions. This paper mainly analyzed and summarized the compatibility theory, bio-active constituents, compatibility effects and action mechanism, and clinical applications of the CMP, which can provide a basis for the depth research and development of the CMP.

The total effect of Chinese medicine pair (CMP) was not the simply addition of two single herbs, but the interaction of their different components. Therefore, the research on the bio-active components of CMP is the basis of CMP compatibility study, and has important significance for revealing the compatibility effect and action mechanism, and creating traditional Chinese medicine (TCM) new drugs. This paper summed up the latest research progress of CMP on the basis of the bio-active components variation regularity of CMP from chemical solutions and content changes in vitro and the actions of CMP on bodies in vivo, in order to further drive the modern basic and applied research of CMP, and to reveal the scientific essence of CMP compatibility.

Chinese medicine pair (CMP) was frequently applied in traditional Chinese medicine (TCM) clinic, and its significance was shown in long-term clinical practices and many accumulated experiences. It is the unique combination of two relatively fixed Chinese medicines in TCM clinic with the basic feature and principle of TCM compatibility, is the most fundamental and the simplest form of TCM formulae with certain theory basis and combinatory reason, which is proven effective. And the unique combination is frequently used for achieving mutual reinforcement or detoxication. CMP is an intermediate point between single herb and many TCM formulae, reflecting the regularity of TCM formulae compatibility and connotation of differential treatment. This paper analyzed and summarized the basic characteristics, development process and research significance of CMP, which aims to lead the modern basic and applied research on compatibility theory of CMP.

Opioid receptor, is classified into three subtypes, mu, kappa and delta, with the mu-type receptor plays important roles in opioid analgesia and opioid addiction. The cDNA encoding mu-type receptor was obtained by RT-PCR from human brain RNA and was cloned into pcDNA3.1(+). The resultant recombinant plasmid pcDNAMORs were transfected into CHO cells by liposome. After PCR identification, the positive clone were treated with agonist and antiagonist were tested for their competence of signal transduction. CHO cells that contained mu-opioid receptor in the expression vector pcDNA3.1(+) acquired naloxone-blockable high-affinity specific binding of morphine and DAMGO. The concentration of cAMP in CHO cells transfected with pcDNAMOR was reduced after binding to morphine and DAMGO, and increased after binding naloxone. These results indicate that the mu-type receptor expreesd on the CHO cell has similar biological property as the nature receptor. The availability of these specific cell lines will facilitate the drug development and promote our understanding the mechanism underlying opiate addiction.

The effects of the feed attractants on Whitmania pigra were studied. The average weight of Wh. pigra were 5.0 g. Arginine was selected as feed attractants, xanthan gum was selected as feed substrate. The times of Wh. pigra going into the inducing room were recorded. The water temperature was 22-25 degrees C during the whole experiment. Arginine that had better inducing effect was chosen to carry on in the gradient experiment. The results showed that the best inducing effect was found when the added amount of arginine was 0.3%, which was close to the arginine content of the natural body fluid of Wh. Pigra and Bellamya purificata, 2.97 mg x g(-1).
