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.

Objective To compare the diagnostic value of adenosine and exercise stress myocardial perfusion imaging (MPI) for detecting coronary heart disease (CHD) in women. Methods One hundred and thirty-eight patients with CHD were randomly divided into two groups: adenosine stress group (n = 69)and exercise stress group (n = 69). All patients underwent myocardial SPECT evaluation. Coronary angiography (CAG), referred as "gold standard" , was performed in each patient within 1 week before or after MPI. The diagnostic value of the two stress MPI was compared with χ2 test or Fisher's exact test. Results In adenosine stress group, the sensitivity, negative predictive value and accuracy were 88.2% (45/51),72.7% (16/22), 88.4% (61/69), respectively, which were not significantly different from those of the exercise stress group (91.7% (44/48), 66.7% (8/12), 81.2% (52/64); χ2 =0. 571, 0. 714, 0.249, P >0.05). However, the false positive rate of adenosine stress (11.1%, 2/18) was significantly lower than that of exercise stress (50.0%, 8/16), P = 0.023. Conclusions Adenosine and exercise stress MPI have similar value for CHD diagnosis in women, however, adenosine stress MPI may have an advantage of low false positive rate.

OBJECTIVEIdiopathic collapsing glomerulopathy (ICG) is a clinically and pathologically distinct variant of focal segmental glomerulosclerosis, which is characterized by proteinuria (often nephrotic range) and rapid progression to end-stage renal failure. The typical pathological changes are global/segmental glomerular collapse, hypertrophy and hyperplasia of podocytes and severe tubulointerstitial lesions. Most ICG patients who have been reported in previous published papers are adults. ICG in children is rare. The study aimed to analyze and investigate clinical manifestations, renal histopathological findings, treatment and outcomes of ICG in children.
METHODSData of two cases of ICG, a 7-year-old boy and a 12-year-old girl, were analyzed. Both of them were Chinese and Han. Clinical characteristics, results of laboratory tests, renal histopathological findings, treatment, outcomes and prognosis of the two children with ICG were retrospectively analyzed. Results were compared with published data.
RESULTSThese two children presented typical clinical features of nephrotic syndrome. The quantity of 24 hr urine protein was 7.6 g/d (0.47 g/kg x d for boy) and 10.67 g/d (0.35 g/kg x d for girl). Both of them had hypertension (blood pressure ranged from 130/90 to 150/110 mmHg) and hypercholesterolemia (15.4 mmol/L for the boy and 11.3 mmol/L for the girl). The serum albumin was 12 g/L for girl and 23 g/L for boy. The creatinine clearance rate gradually decreased from normal range to 30 ml/min for the girl. The histopathological changes in renal biopsy of them were focal segmental or global glomerular collapse, hypertrophy and hyperplasia of podocytes and severe tubulointerstitial lesions. These two cases were steroid-resistant and were treated with pulse intravenous methylprednisolone and pulse intravenous cyclphosphamade in one case, who rapidly progressed to end-stage renal failure and died half a year later. Another one was treated with cyclosporine. He showed continuous hypertention and heavy proteinuria for eight months.
CONCLUSIONICG in the 2 children was a severe disease which presented steroid-resistant nephrotic syndrome and rapidly progressive renal failure. The pathological characteristics was global/segmental glomerular collapse, hypertrophy and hyperplasia of podocytes and severe tubulointerstitial lesions. In children with ICG treatment was difficult and the prognosis was poor.

The aim of this study is to investigate the anti-inflammatory effect of the adenosine derivative N6-(3-hydroxylaniline) adenosine (WS070117M1) on cigarette smoke plus LPS (lipopolysaccharide)-induced chronic obstructive pulmonary disease (COPD) in mice and its mechanism. COPD model was established by exposing male BALB/c mice to cigarette smoke and challenged with LPS inhalation. Supernatants of bronchoalveolar lavage fluid (BALF) were harvested and IL-1β, IL-6, IL-8 and TGF-β1 levels were measured by ELISA (enzyme-linked immunesorbent assay). The number of total white blood cells and neutrophils in bronchoalveolar lavage fluid was counted separately. Lung tissue was stained with Mayer 's hematoxylin and eosin for histopathologic examination. pAMPKa protein expression and distribution of lung tissue were analyzed by immunohistochemistry method. In vitro, levels of AMPKα phosphorylation in phorbol-12- myristate-13-acetate (PMA) differentiated THP-1 cells was detected by immunohistochemistry, IL-8 level in supernatants of cigarette smoke condensate stimulating PMA differentiated THP-1 cells was measured by ELISA. The results showed that WS070117M1 treatment significantly activated AMPKa in the lung tissue. It also resulted in down regulation of IL-1β, IL-6, IL-8 and TGF-β1 levels in bronchoalveolar lavage fluid and IL-8 level in cigarette smoke condensate stimulating PMA differentiated THP-1 cells. In addition, WS070117M1 could inhibit the recruitment of total white blood cells and neutrophils. These results suggest that WS070117M1 may alleviate the airway inflammation by activating AMPK in the lung tissue.
