This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

Objective To analyze the assessment results and summary the work experience of malaria elimination in Baise City. Methods According to The malaria elimination evaluation schemes of Guangxi(2014 edition),the examination and evaluation of malaria elimination were carried out and all the results were analyzed in 12 counties(county?level city or district) of Baise City from 2014 to 2015. Results Since 2009,there were no local malaria cases and imported secondary cases in Baise City for the 6 consecutive years,and the detailed data were collected and the self?assessment reports of malaria elimination were written in all the counties. There was no omission or delay of malaria case reports in the 12 counties. The highest score of the ex?amination and evaluation was 96.58 points,the lowest was 90.76 points,and the average was 93.77 points. The biggest impact on the evaluation scores was“on?site examination”. Conclusion All the 12 counties(county?level city or district)of Baise City have passed the municipal examination and evaluation of malaria elimination,and the key of next work is malaria monitoring, timely finding and treating the imported malaria patients,and to guarantee no imported secondary cases.

The chemical constituents from polarity part in the roots of Angelica dahurica var. formosana cv. Chuanbaizhi were studied in this paper. The compounds were separated and purified by repeated column chromatographic methods on silica gel and HPLC, and the chemical structures of compounds were determined by spectral data analyses. Fourteen compounds were obtained and identified as tert-O-β-D-glucopyranosyl-(R)-byakangelicin (1), (2"S) -3"-O-β-D-glucopyranosyl-oxypeucedanin hydrate (2), marmesinin (3), sec-O-β-D-glucopyranosyl-byakangelicin (4), isofraxidin-7-O-β-D-glucopyranoside (5), benzyl-O-β-D-glucopyranoside (6), 8-O-β-D-glycopyranosylxanthotoxol (7), prenyl-O-β-D-glucopyranoside (8), scopolin (9), (2' R) -5'-hydroxymarmesin-5'-O-β-D-glucopyranoside (10), (2'S,3'R) -3'-hydroxymarmesinin (11), skimmin (12), benzyl-O-β-D-apiofuranosyl-(1"--> 6')-β-D-glucopyranoside (13), and decuroside IV (14). Among them, compounds 2, 5, 6, 8, and 10-13 were obtained from the roots of title plant for the first time.

Surface electromyogram (sEMG) may have low signal to noise ratios. An adaptive wavelet thresholding technique was developed in this study to remove noise contamination from sEMG signals. Compared with convention- al wavelet thresholding methods, the adaptive approach can adjust thresholds based on different signal to noise ratios of the processed signal, thus effectively removing noise contamination and reducing distortion of the EMG signal. The advantage of the developed adaptive thresholding method was demonstrated using simulated and experimental sEMG recordings.

Objective To analyze the results of treatment of complicated tibial plateau fractures with open reduction and internal fixation with bilateral plates .Methods 29 elder patients with C type tibial platform fractures underwent internal fixation with bilat-eral plates and bone grafting .Fixation with bilateral plates was performed during operation with dynamic compression plate or 1/3 Tubular steel plate placed medially and the dissection plate or LISS system ones inserted laterally after the underlying separation . Meanwhile ,sufficient bone grafting during operation could effectively support reduction of articular surface .Results All patients were followed up of an average of 13 .8 ± 2 .43 months .According to Rasmussen score standard ,the excellent and good rate was 82 .7% .There was significant difference of TPA and PA between postoperation and postoperation one year later .Conclusion It is a simple and effective method to treat complicated elder tibial platform fractures with bilateral plates .It will improve the effect and re-duce complications significantly to perform sufficient bone grafting intraoperatively ,and make the drainage unobstructed and do the early functional exercises postoperatively .
