A hands-free method is proposed to control an electric powered wheelchair （EPW） based on surface electromyography （sEMG） signals. A CyberLink device is deployed to obtain and analyze forehead sEMG signals generated by the facial movements. The autoregressive （AR） model is used to extract sEMG features. Then, the back-propagation artificial neural network （BPANN） is proposed to recognize different facial movement patterns and improved by Bayesian regularization and Levenberg-Marquardt （LM） algorithm. A sEMG based human-machine interface （HMI） is designed to map facial movement patterns into corresponding control commands. The experimental results show that the method is simple, real-time and have a high recognition rate.

Three perovskite-type catalysts prepared by citric acid method are applied to remove phenol from gas streams with the total flow rate of 300 mL/min, corresponding to a GHSV of 10,000/hr. LaMnO3 catalyst is first prepared and further partially substituted with Sr and Cu to prepare ***.2MnO3 and ***.203, and catalytic activities and fundamen- tal characteristics of these three catalysts are compared. The results show that phenol removal efficiency achieved with ***.203 reaches 100% with the operating temperature of 200℃ and the rate of mineralization at 300℃ is up to 100%, while the phenol removal efficiencies achieved with ***.2MnO3 and LaMnO3 are up to 100% with the operating temperature of 300℃ and 400℃, respectively. X-ray photoelectron spectroscopy （XPS） analysis shows that the addition of Sr and Cu increases the lattice oxygen of ***.203, and further increases mobility or availability of lattice oxygen. The results indicate that ***.203 has the best activity for phenol removal among three catalysts prepared and the catalytic activity of phenol oxidation is enhanced by the introduction of Sr and Cu into LaMnO3. Apparent activation energy of 48 kJ/mol is calculated by Mars-Van Krevelen Model for phenol oxidation with ***.203 as catalyst.

On the basis of real-world clinical data,the study aimed to explore the effect and mechanisms of the treatment plan of“traditional Chinese medicine(TCM)regulating liver regeneration.”A total of 457 patients with HBV-related liver failure were retrospectively *** patients were divided into three groups:the modern medicine control group(MMC group),patients treated with routine medical treatment;the control group combining traditional Chinese and Western medicine(CTW),patients treated with routine medical treatment plus the common TCM formula;and the treatment group of“TCM regulating liver regeneration”(RLR),patients treated with both routine medical treatment and the special TCM formula of *** 8 weeks of treatment,the mortality of patients in the RLR group(12.31%)was significantly lower than those in the MMC(50%)and CTW(29.11%)*** bilirubin level significantly decreased and albumin increased in the RLR group when compared with the MMC and CTW groups(P<0.05).In addition,there were significant differences in the expression of several cytokines related to liver regeneration in the RLR group compared with the MMC *** treatment can decrease jaundice,improve liver function,and significantly reduce the mortality in patients with HBV-related liver *** mechanism may be related to the role of RLR treatment in influencing cytokines related to liver regeneration.

OBJECTIVE: To study the daily administration times of Canhuang tablet(CHT) for treating jaundice in rats based on a pharmacodynamic/ pharmacokinetic ***: Rats were modeled by 4% 1-Naphthylisothiocyanate(75 mg/kg, p.o.). After 48 h, CHT was given(p.o.) at 0.75 g/kg once a day, 0.375 g/kg twice a day, and 0.25 g/kg three times a day. Blood was collected from the orbital sinus at different intervals. Levels of liver enzymes and bilirubin were detected using these blood samples. Bile was collected and determined after the first administration of CHT. High-performance liquid chromatography was used to determine the concentration of berberine in bile simultaneously. Time-effect and time-dose curves were then ***: Compared with rats taking CHT twiceand three times a day, the total amount of bile within 10 h of rats taking CHT once a day were 1.32-and 1.47-fold higher, respectively. There was good consistency between the pharmacokinetics of berberine and the pharmacodynamics of the effect on liver enzymes and bilirubin in vivo. The pharmacokinetic analyses showed that rats administered CHT once daily maintained a higher concentration of berberine in bile for a longer period than rats administered CHT two- and three-times ***: In jaundiced rats, taking CHT once a day is better than taking CHT twice or three times a day. These data may provide a reference for the clinical application of CHT.

AIM: To investigate the cytotoxicity, anti-inflammatory activity, and action mechanism of root bark extracts of Acanthopanax henryi. METHOD: The hot methanol extract of the root bark of A. henryi was subjected to XAD-4 column chromatography eluting with a gradient of methanol in water. The cytotoxicity and anti-inflammatory effects of the MeOH fractions were evaluated on the inhibition on lipopolysaccharide(LPS)-induced nitric oxide, prostaglandin E2, interleukin-1β, and interleukin-6 production in RAW 264.7 macrophages. RESULTS: The 80% MeOH fraction was a better inhibitor of LPS-induced NO, PGE2, IL-1β, and IL-6 production, and expression of inducible nitric oxide synthase(iNOS) at the protein levels in a concentration-dependent manner. CONCLUSION: The 80% MeOH fraction of A. henryi root bark has significant anti-inflammatory activity. This provides a pharmacological basis for clinical application for the treatment of inflammation.
