Objective To develop a method for simultaneous determination of three hydrophilic components and two lipophilic components in Radix et Rhizoma Salviae Miltiorrhizae. Methods The RP-HPLC method was performed by using a Welchrom C18 column(250 mm×4.6 mm,5 μm)with a mobile phase of acetonitrile (A)-0.1%phosphoric acid(B). The gradient elution program was as follows:0-15 min,10%→12%A;-35 min,12%→20%A;-45 min,20%→60%A;-65 min,60%→65%A;-80 min,65%→80%A;-90 min,10%A. The flow rate was kept at 1.0 mL?min-1 . The detection wavelength was set at 280 nm. The column temperature was 30 ℃ .

Objective To evaluate the swallowing function of patients with dysphagia after brainstem injury using manofluorography (MFG),analyzing the abnormal biomechanical and kinematic parameters as well as any correlation between changes in the pharynx and the upper esophageal sphincter (UES) measured manometrically and changes in the kinematics of the hyoid bone.Methods Thirteen patients with dysphagia after brainstem injury (the patient group) and 13 healthy participants (the control group) underwent manofluorography.Kinematics and biomechanical changes during swallowing were compared between the two groups and the correlations between the observations were analyzed.Results The patient group showed significantly lower maximum pressure and rate of pressure change at the base of the tongue and in the hypopharynx,as well as less hyoid anterior displacement,smaller and briefer UES opening,but significantly higher minimum pressure at UES relaxation.The duration of tongue root elevation and hypopharynx pressure was also shorter than in the control group,on average.There was a negative correlation between hyoid anterior displacement and the minimum pressure on UES relaxation in the control group,and a positive correlation between hyoid anterior displacement and the maximum pressure at the base of the tongue and in the hypopharynx in the patient group.Conclusions The concurrent use of manometry and video-fluorography for evaluating dysphagia can be an objective and effective diagnostic tool for the comprehensive evaluation of swallowing function.

The nitrite-reducing activity of aerobic denitrifying bacterial strain N6-1 was studied. It showed that the nitrite-reducing activity reached the highest at 30℃, 120 r/min, pH 8.5 and C/N ratio 12, using CH3COONa and NaNO2 as the sole carbon source and nitrogen source, respectively. When the initial NaNO2 concentration was 2 g/L, NO2--N was reduced completely after 20 hours cultivation with the reducing rate of 20.3 mg/L?h. There would be no effect on its nitrite-reducing activity in the present of 1.5% NaCl or 1% peptone. The cell concentration could reach 1.2?1011 CFU/mL after 24 hours cultivation in 10 L fermentor.

OBJECTIVETo investigate the inhibitory effect of arresten on the growth of SGC-7901 tumor xenograft nude mice model with the localized expression of arresten.

METHODSThe secretable eukaryotic expression vector pcDNA3.1 (+)-ss-arresten was constructed by molecular clone strategy, and then was transfected into human gastric cancer cell line SGC-7901 using liposome. The Western blot method was used to examine whether the protein was secreted into cell medium, and the biological behaviors of genetically modified SGC-7901 cell clone was further investigated with MTT and flow cytometry analysis system (FCAS). At last, the SGC-7901 cells expressing arresten were implanted subcutaneously into nude mice, and the weights of tumor xenografts were recorded and analyzed.

RESULTSThe eukaryotic expression vector containing secretable arresten cDNA was constructed successfully. The SGC-7901 cell line with the character of expression of arresten was obtained. The growth of arresten cDNA genetic-modified SGC-7901 tumor xenograft was suppressed.

CONCLUSIONSThe anti-tumor effect of arresten in the SGC-7901 xenograft is by inhibition of the proliferation of vascular endothelial cell of the tumor.
