ABSTRACT

Objective:To study the anti-inflammatory and analgesic effects of the volatile oil from Piper puberulum ( Benth. ) Max-im. in Guizhou. Methods:Fifty KM mice were randomly divided into five groups (10 ones in each), the model control group (sa-line), low concentration volatile oil group (0. 125 ml/100 ml), medium concentration volatile oil group (0. 25 ml/100ml), high con-centration volatile oil group (0. 5 ml/100 ml) and aspirin group (3 mg·ml-1). Mouse ear swelling induced by xylene and skin capil-lary permeability were used to evaluate anti-inflammatory activity of the volatile oil from Piper puberulum ( Benth. ) Maxim. in Guizhou. Acetic acid-induced abdominal eonstrietion test and hot-plate test were applied to evaluate anti-analgesic activity of the vola-tile oil from Piper puberulum ( Benth. ) Maxim. In Guizhou. Results:Compared with that in the model group, the mouse ear swelling in the medium concentration volatile oil group, high concentration volatile oil group and aspirin group was significantly reduced ( P<0. 05). The skin capillary permeability in the high concentration volatile oil group and aspirin group was significantly reduced (P<0. 05 or P<0. 01). Compared with that in the model group, the writhing times in the medium concentration volatile oil group, high concentration volatile oil group and aspirin group were significantly reduced (P<0. 05 or P<0. 01). The pain threshold in the high concentration volatile oil group was effectively reduced (P<0. 05 or P<0. 01). Conclusion: The volatile oil from Piper puberulum ( Benth. ) Maxim. in Guizhou has promising anti-inflammatory and analgesic activities.

ABSTRACT

OBJECTIVE:To investigate the possibility of constructing anti-cancer drug in-situ hydrogel with self-assembling peptide RAD16-Ⅰ. METHODS:The rheological parameters as storage modulus(G′),loss modulus(G″)and phase angle(Δ)of 0.1%,0.2% and 0.5% RAD16-Ⅰ solution containing paclitaxel or not were determined by rheometer before and after mixing with isometric phosphate buffer solution (PBS);RAD16-Ⅰ solution containing paclitaxel or not were mixed with breast cancer MDA-MB-435S cells culture medium to obtain hydrogel,the status and effect of which on cell morphology were observed by in-verted microscope (compared with paclitaxel solution). RESULTS:In RAD16-Ⅰ solution containing paclitaxel or not,G′was close to or slightly higher than G″,and G′and G″had changed slightly as the concentration of peptide increased. Compared with not mixed with PBS,G′increased significantly in concentration-dependent manner after mixed with PBS,and G″also increased but was slighter than G′;Δ decreased significantly. In cell culture media,RAD16-Ⅰ solutions containing paclitaxel could form hy-drogel and maintain their gel form,cancer cells kept same morphology after treated with hydrogel and same concentration of pacli-taxel solution for same time. CONCLUSIONS:RAD16-Ⅰ solutions containing paclitaxel can form hydrogel under simulated physi-ological conditions,which can maintain their gel form and have anti-cancer effect of paclitaxel.

ABSTRACT

The real-time and wireless mobile has become the trend of electrocardiogram (ECG) monitoring system for atrial fibrillation (AF). At present, the ECG with multi-leads (12 leads) is needed by most of AF signal extraction algorithms in order to extract effective AF waves. However, it is not very convenient for patients' movements in a multi-lead ECG monitoring system. Although the traditional template matching method is for single-lead ECG extraction, it is less robust than blind source extraction algorithm, and is affected severely by noise. In view of this,we put forth a new real-time algorithm for extracting AF from the singlelead ECG, using non-stationary heartbeat series during AF to extend dimension (segmentation), and then applying a blind source extraction algorithm to extract the effective AF signal. Experiment results showed that this method could be used to extract AF signal effectively from a single-lead ECG data. Therefore, it is suitable to apply this method to Wireless Monitoring System using single-lead ECG.
