OBJECTIVETo observe the effect of acupunture at Shenmen (HT 7) and Daling (PC 7) on different cerebral functional regions by Functional Magnetic Resonance Imaging (MRI), and discuss the relative specificity of effect of these two acupoints.

METHODSTen healthy right-handed volunteers were enrolled in this research. Under the scan of fMRI with the pattern of "rest-stimulation-rest-stimulation-rest", acupuncture stimulation was given at Shenmen (HT 7) and Daling (PC 7) on the right side, and all the data were analyzed with Matlab software and SPM5 package to observe the activated cerebral regions.

RESULTSThe activated brodmann areas by acupuncture at Shenmen (HT 7) were mainly BA10 BA13, BA47, BA22 on the left side and BA40 BA44 on the right side, while the activated areas by acupunoture at Daling (PC7) were BA46, BA47, BA22 BA10. BA45 on the left side and BA44 BA9, BA6. BA40 on the right side.

CONCLUSIONThe activated cerebral functional regions of acupuncture stimulation at Shenmen (HT 7) and Daling (PC 7) are not exactly the same, which indicates that the acupuncture effects of the two acupoints are specific. With the same activated areas of language and cognitive function, the Shenmen (HT 7) specializes in emotion control while the Daling (PC 7) could active the autonomic nerve function area.

OBJECTIVETo investigate the value of fractional nitric oxide concentration in exhaled breath (FeNO) in assessing the level of asthma control in children.

METHODSA total of 226 asthmatic children were divided into controlled asthma (n= 86), partially controlled asthma (n=63), and uncontrolled asthma groups (n=77). Ninety healthy children were enrolled as controls. FeNO was measured for both asthmatic and healthy children using the Swedish-designed NIOX system.

RESULTSThe control group had an FeNO of 14±6 ppb, the controlled asthma group had an FeNO of 29±26 ppb, the partially controlled asthma group had an FeNO of 32±30 ppb, and the uncontrolled asthma group had an FeNO of 40±32 ppb. The three asthma groups showed significantly higher FeNO than the control group (P<0.05). The uncontrolled asthma group showed significantly higher FeNO than the controlled asthma group (P<0.05), but there were no significant differences in FeNO between the partially controlled and uncontrolled asthma groups and between the partially controlled and controlled asthma groups (P>0.05).

CONCLUSIONSAsthmatic children have significantly higher FeNO than healthy children, and FeNO is correlated with the level of asthma control.

OBJECTIVETo observe the maintenance effect of polyglycosides of Tripterygium wilfordii (GTW) on remission in postoperative Crohn disease (CD).

METHODSFrom 2005 to 2007, 45 adult cases of postoperative Crohn disease were randomly divided into two groups, GTW group and mesalazine group, which received GTW and mesalazine treatment respectively. CD activity index (CDAI) and clinical markers were collected at 0, 3, 6, 12 months or at the onset of symptoms. Ileocolonoscopy was performed at the end of the trial (1 year after operation) or at the onset of symptoms, and recurrence score were recorded.

RESULTSNo clinical recurrence was ascertained in both groups at 3 months. Four patients (18.2%) in GTW group relapsed and 5 (21.7%) in mesalazine group relapsed at 6 months (P=0.530). Seven patients (31.8%) in GTW group and 9 (39.1%) in mesalazine group relapsed at one year (P=0.421). Ten patients (45.5%) in GTW group had endoscopic recurrence compared with 14 (60.9%) in mesalazine group at one year(P=0.231). There were no significant differences between two groups.

CONCLUSIONGTW is similar to mesalazine in maintenance of remission of postoperative Crohn disease.

OBJECTIVETo evaluate the clinical value of iodine[131I] metuximab infusion combined with transcatheter arterial chemoembolization (TACE) for treating cases of post-intervention relapse of mid or advanced stage hepatocellular carcinoma (HCC).

METHODSSixty patients who were diagnosed between March 2009 and June 2010 with relapse of mid or advanced stage HCC following previous intervention with various standard clinical methods were recruited for study. The patients were randomly and equally divided into a control treatment group (CG; receiving TACE therapy alone) and an experimental treatment group (TG; receiving TACE combined with iodine [131I] metuximab injection). For all patients, licartin was first perfused into the tumor feeding artery and then the TACE procedure was performed 20 min later. Liver function markers and routine blood parameters, including alpha-fetoprotein (AFP) and clotting time, were examined at one week and one month after the treatment. Enhanced computed tomography or magnetic resonance imaging of the liver was performed at one month after treatment and thereafter on a bi-monthly follow-up schedule. The World Health Organization's tumor evaluation standard was used to assess the therapeutic effects in each group. Results of laboratory tests (pre- and post-treatment), reported complications, and side-effects were evaluated for their contributions to time of tumor progression (TTP) and survival time.

RESULTSPatients in the TG and CG groups had similar blood cell counts at pre-operative and 1-week postoperative time points. The TG group showed a significantly reduced level of AFP following treatment, but it was not significantly different from the level in the CG group. The TG group did however show significantly different levels of liver functional parameters (all P less than 0.05) and significantly higher TTP (4.84+/-4.11 vs. CG: 2.54+/-2.08 months; t = -2.13, P less than 0.05) and average survival time (7.05 vs. 5.15 months; x2 = 4.24, P = 0.039). The rates of partial response (PR), slight remission (MR), unchanged status (SD) and progressive disease (PD) were 16.7%, 37.5%, 25.0% and 20.8% in the TG group, and 8.7%, 17.4%, 21.7% and 52.2% in the CG group. The therapeutic effect rate (CR + PR + MR) and reaction rate (CR + PR + MR + SD) was significantly different between the two groups (P = 0.048). No serious adverse effects were reported.

CONCLUSIONTACE combined with iodine [131I] metuximab injection is a safe and effective procedure for prolonging the survival and TTP of patients with HCC relapse following prior therapeutic intervention.

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.
