OBJECTIVE:To compare the contents of loganic acid,swertiamarin,6′-O-β-D-glucosyl gentiopicroside,gentiopi-croside,sweroside,isoorientin and isovitexin in wild and cultivated Gentiana officinalis,and to provide basis for rational use of G. officinalis. METHODS:UPLC method was adopted. The separation was performed on ACQUITY UPLC? BEH C18 column (50 mm × 2.1 mm,1.7 μm) with mobile phase consisted of methanol-0.04% phosphoric acid (gradient elution) at the flow rate of 0.3 ml/min. The detection wavelength was set at 242 nm,and column temperature was 30 ℃. RESULTS:For loganic acid,swertiama-rin,6′-O-β- D-glucosyl gentiopicroside,gentiopicroside,sweroside,isoorientin and isovitexin,a good linearity was obtained in the range of 2.1-537.1 μg,1.05-270 μg,0.92-236 μg,11.1-2 830 μg,0.75-192 μg,0.167-102 μg,0.216-52.80 μg(r≥0.999 5), respectively. Their average recoveries were 97.72%-99.84%(RSD≤3.39%,n=6). The contents of loganic acid,swertiamarin, 6′-O-β-D-glucosyl gentiopicroside,gentiopicroside,sweroside and isoorientin in the wild sample were higher than in the cultivat-ed;the content of isovitexin was lower than the cultivated,but there was no statistical significance(P>0.05). The sum of gentiopi-croside and loganin acid content were all higher than 2.5% in both wild and cultivated samples,and met the requirements of 2015 edition of Chinese Pharmacopoeia(first part). CONCLUSIONS:The content difference of 7 indicative constituents in wild and cul-tivated G. officinalis is not statistically significant,and the indicative constituents of the pharmacopoeia is qualified.

Isothermal nucleic acid amplifications, as powerful as polymerase chain reaction but functioning at a constant temperature, are considered to be very promising technique in achieving point-of-care gene diagnostics. However, until now, their practical applications are still seriously lagged by the bad reliability resulting from the problems such as false positive amplification and low signal amplitude. In this work, a universal transduction method in which any sequence ( including loop-mediated isothermal amplification products) could be transduced via a hairpin transducer into a catalyst of a well-engineered circuit (catalytic hairpin assembly, CHA) was established. Because CHA circuit could amplify tens to hundreds fold with especially high sequence specificity, it could provide both accuracy and high amplitude for sequence detection. And for a new targeting sequence, the only sequence needed to be changed was the hairpin transducer. Due to the importance of the transducer, we provided and verified a universal designing rule-set to guarantee the transducing efficiency ( signal to background ratio) of the transducer. Transducers designed following this rule set were then proved to be very efficient in detecting pathogen gene targets. As less as near single molecule ( 20 copies ) of pathogen genes could be detected with significant fluorescent and electrochemical signals.

Objective Toinvestigatetheeffectofmicroribonucleicacid(miRNA)-155ontwo subtypesofregulatoryTcell(Treg):inducedTreg(iTreg)andnaturalTreg(nTreg).Methods NaveT cells and nTreg were isolated from peripheral blood mononuclear cell (PBMC)of healthy donors by magnetic cell sorting. Cells were divided into 3 groups during culture,including control group (nave T cells were cultured with the presence of interleukin-2 ),iTreg group (nave T cells were cultured with the presence of interleukin-2 and transforming growth factor-β)and nTreg group(nTreg cells was cultured with interleukin-2).Each group was divided into 3 subgroups (none,scramble or miRNA-155 antagomir subgroup,3 wells in each subgroup). Expression level of miRNA-155 gene of none subgroup in 3 groups was detected by low density chip analysis method. The levels of surface marker CD25,Foxp3,CD127 of each subgroup in 3 groups were detected by flow cytometry. The percentage of CD4 +CD25 +Foxp3 +SOCS1 +Treg and suppressive function of Tregofeachsubgroupin3groupswerealsodetectedbyflowcytometry.Results Comparedwithcontrolgroup and iTreg group,the expression level of miRNA-155 was significantly lower and SOCS1 was significantly higher in nTreg group (all in P<0.05 ). After the addition of miRNA-155 antagomir,no significant change was observed in the important surface markers of Treg like Foxp3,CD25,CD127. Compared with control group and iTreg group,the expression of SOCS1 in nTreg group increased significantly (both in P <0.05 ). The expression level of miRNA-155 of none subgroup in iTreg group was lower. The expression of SOCS1 increased after the miRNA-155 was inhibited by antagomir (miRNA-155 antagomir subgroup). In iTreg group,the suppressive function of Treg in miRNA-155 antagomir subgroup was higher than that in none subgroup at the ratioof1∶8,1∶16and1∶32(allinP<0.05).Conclusions AntagonismofmiRNA-155invitrohasno significant effect on the suppression function of nTreg,but can increase the SOCS1 expression level and suppression in vitro of iTreg.

Objective:To observe the effect of oral-facial muscle training applying virtual reality technology (VR) and of action observation therapy on the salivation of children with cerebral palsy (CP).Methods:Sixty CP children with uncontrolled salivation were randomly divided into a control group and an observation group, each of 30. In addition to conventional rehabilitation treatment, the control group received routine tongue muscle training, buccal lip muscle training, ice stimulation, and Masako swallowing training. The observation group received oral-facial muscle training based on action observation therapy in a virtual environment. Both groups were trained 30min per day, 5 times a week for 3 weeks. Before and after the treatment, drooling (DDSS) and swallowing function scores were evaluated. Integrated surface electromyography (iEMG) of the buccinator and orbicularis oris muscles was also performed.Results:After treatment, a significant decrease was observed in the average DDSS and the swallowing function scores of both the control and observation groups, along with a significant increase in the average root mean square values of the buccinator and orbicularis oris iEMGs of both groups. However, the average DDSS score of the observation group was significantly lower than that of the control group, while the average iEMG readings were significantly better.Conclusion:VR-based action observation oral-facial muscle training is a more effective supplement to conventional rehabilitation treatment than conventional oral-facial muscle training in improving the salivation of children with CP.
