To investigate the induction of apoptosis of mouse colonic adenocarcinoma CT26 cells by recombinant Clostridium difficile toxin B (rTcdB), CT26 cells were exposed to different concentrations of rTcd B. Inhibition of cell proliferation was measured by MTT assay. The activation of Caspase 3 was measured by colorimetric method. Cell morphological analysis and flow cytometry were performed to confirm cell apoptosis. rTcd B inhibited the proliferation of CT26 cells in a timeand dose-dependent manner. Caspase 3 activity in CT26 cells was elevated remarkably after rTcd B exposure for 6 h, 12 h, 18 h or 24 h, as compared with the control group. Morphological changes were observed by fluorescence microscopy. The exposure of rTcd B to CT26 cells induced a timeand dose-dependent apoptotic cell death as determined by flow cytometry analysis. The results showed that recombinant Clostridium difficile toxin B induced apoptosis of CT26 cells.

BACKGROUND: Sepsis is a common complication of infections, burns, traumas, surgeries, poisonings, and post-cardiopulmonary resuscitation. The present study aimed to investigate prognostic value of CD4+CD25+ regulatory T cells (Treg) in peripheral blood of patients with sepsis. METHODS: Periphery blood from 28 patients diagnosed with sepsis was collected on day 1 and 7 after hospitalization in the ICU of Shanghai Changzheng Hospital between December 2013 to April 2014. The blood was used for analyses of Treg ratio using flow cytometry and for analyses of blood routine test, C-reactive protein (CRP), bilirubin, procalcitonin (PCT), and coagulation. APACHE II and sequential organ failure assessment (SOFA) scores were also investigated. The results were compared between two outcome groups of survival or death to evaluate prognostic value for sepsis. RESULTS: The patients had an average age of 60.36±15.03 years, APACHE II score 16.68±7.00, and SOFA score 7.18±3.78. Among the 28 patients, 12 had severe trauma (42.9%), 10 had septic shock (35.7%), and 9 (32.2%) died. The median ratio of Tregs was 2.10% (0.80%, 3.10%) in the survival group vs. 1.80% (1.15%, 3.65%) in the death group (Z=–0.148, P=0.883) on day 1; however it was significantly changed to 0.90% (0.30%, 2.80%) vs. 5.70% (2.60%, 8.30%) (Z=–2.905, P=0.004). CONCLUSION: With better prospects for clinical application, dynamic monitoring of Tregs ratio in peripheral blood has potential value in predicting prognosis of sepsis.

To investigate the effect of Jiawei Foshou San and its various combined administration on hepatic P450 enzyme activity and hepatocyte morphology in rats. Rats were orally administered with drugs for four weeks and then sacrificed to prepare liver microsomes. The liver microsomes were incubated with the cocktail method; The metabolites were determined with the rapid liquid chromatography with tandem mass spectrometry (LC-MS/MS) to investigate the hepatocyte P450 enzyme activity. In addition, the hepatic pathological changes were observed by using the hematoxylin and eosin (HE) staining. Compared with the control group, the enzyme activity of CYP1A2 and CYP3A4 in the Jiawei Foshou san group showed a significant rise (P < 0.05); the enzyme activity of CYP1A2, CYP2C9, CYP2D6, CYP2E1 and CYP3A4 in the ferulic acid + ligustrazine group and the ligustrazine + tetrahydropalmatine group showed a significant rise (P < 0.05) ; the enzyme activity of CYP1A2, CYP2D6 and CYP2E1 in the ligustrazine group showed a significant rise (P < 0.05); the enzyme activity of CYP3A4 in the ferulic acid group showed a significant reduction (P < 0.05). After the administration with various drugs, the hepatocyte morphologies in the ferulic acid group and the ligustrazine group were normal. The pathological changes were observed in the tetrahydropalmatine group, such as unclear boundary of hepatic lobules, disordered hepatic cell arrangement, blurred edge, anisokaryosis and infiltration of inflammatory cells. The ferulic acid + tetrahydropalmatine group, the ligustrazine + tetrahydropalmatine group and the Jiawei Foshou San group also showed inflammatory infiltration, but with less pathological changes, particularly the Jiawei Foshou San group. The study result shows that Jiawei Foshou San can induce the enzyme activity of CYP1A2 and CYP3A4, and ligustrazine may be the effective substance for inducing CYP1A2. Its combination with ferulic acid and ligustrazine can significantly reduce the liver toxicity of tetrahydropalmatine.

To detect the in vitro probe microdialysis recoveries based on an HPLC-DAD method for simultaneous quantification of nine active ingredients (ephedrine, pseudoephedrine, methylephedrine, amygdalin, liquiritin, cinnamyl alcohol, cinnamic acid, cinnamaldehyde and glycyrrhizic acid) in Mahuang decoction, which provides reference for in vivo pharmacokinetic study. The concentrations of nine active ingredients in dialysate were detected by HPLC-DAD, to investigate the effect of flow rates (incremental method and subtraction method) and intraday stability of the probe recoveries and medium concentrations on the recoveries. Nine active ingredients could be well separated in 52 min. At the perfusion rate of 1.0 μL x min(-1), the relative recoveries of ephedrine, pseudoephedrine, methylephedrine, amygdalin, liquiritin, cinnamyl alcohol, cinnamic acid, cinnamaldehyde and glycyrrhizic acid were (50.95 ± 0.82)%, (52.74 ± 1.13)%, (51.29 ± 0.51)%, (32.56 ± 0.84)%, (45.36 ± 0.83)%, (70.94 ± 0.99)%, (69.98 ± 2.30)%, (71.68 ± 0.63)%, and (22.14 ± 0.48)%, respectively. And the probe kept steady in 7 hours. At the same medium concentration, the probe recoveries decreased exponentially with the increase in flow rates. The recoveries of seven ingredients detected by these two methods were similar at certain flow rates, except for amygdalin and cinnamaldehyde. At the same flow rate, the relative recoveries of cinnamyl alcohol, cinnamic acid and cinnamaldehyde changed greatly (9.55%-16.2%) and the others six ingredients had less change (3.27%-5.71%) with the changes in medium concentrations. Microdialysis method could be used to detect the in vitro recoveries of nine ingredients in Mahuang decoction. Reverse dialysis method could be used for the in vivo probe recovery calibration of ephedrine, pseudoephedrine, methylephedrine, liquiritin, cinnamyl alcohol and cinnamic acid at the flow rate of 2.0 μL x min(-1).

OBJECTIVETo compare the efficacy of Chinese herbal medicine (therapy A) or Chinese herbal medicine plus indomethacin (therapy B) with that of indomethacin alone (therapy C) in treating polyhydramnios.
METHODSLiteratures published up to April 2012 were retrieved from PubMed, Embase and Cochrane library, Chinese National Knowledge Infrastructure (CNKI), Chinese Scientific and Technological Periodical Database (VIP), Wangfang, and Traditional Chinese Medicine online. Two researchers collected data independently. The assessment of methodological quality was based on Cochrane handbook and the materials were analyzed with software RevMan 5.1.2. The outcome measure index was relative risk or difference of mean value (95% confidence interval). The following outcomes were evaluated (1) general clinical improvement rate; (2) maximum vertical pocket depth; (3) amniotic fluid index (AFI) value; (4) rate of fetal ductus arteriosus constriction; (5) incidence of adverse events.
RESULTSBased on the search strategy, 5 trails involving 1017 patients were finally included. Compared with therapy C, therapy A decreased the rate of fetal ductus arteriosus constriction (P<0.01). Therapy B was more effective than therapy C in general clinical improvement and decrease of AFI for polyhydramnios (P<0.01). No serious adverse events were reported in therapy A and therapy B.
CONCLUSIONSCompared with therapy C, therapy A and therapy B may appear to be more effective for polyhydramnios. However, the exact effect needs to be confirmed with well-designed large-scale clinical trials.

OBJECTIVETo investigate the role of non-high density lipoprotein cholesterol (non-HDL-C) in the assessment of cardiovascular disease (CVD) risk factors such as hypertension, pre-diabetes and diabetes in obese children.
METHODSAccording to the presence of complications (hypertension, pre-diabetes and diabetes), 810 children with central obesity were divided into two groups: one group with complications (n=499) and one group without complications (n=311). One hundred and sixty-four age- and sex-matched children served as the control group. Logistic regression analysis and receiver operating characteristic (ROC) curves were used to analyze the detection of non-lipid CVD risk factors by seven lipid markers.
RESULTSThe prevalence rates of hypertension and pre-diabetes were significantly higher in obese children with high non-HDL-C concentrations (≥3.76 mmol/L). After adjusting for waist circumference Z-scores, the area under the ROC curve for non-HDL-C was 0.680 to detect non-lipid CVD risk factors, while the areas for low-density lipoprotein cholesterol, total cholesterol and apoprotein B were 0.659, 0.669 and 0.647 respectively.
CONCLUSIONSCompared with the other lipid markers, non-HDL-C is a better predictor for non-lipid CVD risk factors in obese children. Measurement of non-HDL-C concentations is recommended for obese children.
