OBJECTIVETo observe the primary prevention role of Wuling Capsule (WC) on poststroke depression (PSD) patients.
METHODSAcute stroke patients were recruited and randomized into 2 groups by stratification, 55 in each group. All patients received same routine treatment of cardiovascular diseases. Patients in the experimental group additionally took WC (0.33 g each pill), 3 pills per day, three times per day; while those in the control group additionally took placebos, 3 pills per day, three times per day. Two weeks consisted of one therapeutic course. The diagnosis of PSD was performed once every other week. Those in accordance with PSD diagnosis discontinued any drug therapy. Those not in accordance with PSD diagnosis continued the drug therapy for 1-12 therapeutic course(s) (in total of 6 months). If they were still not in accordance with PSD diagnosis, then they discontinued the drug therapy. The morbidity of PSD, the average time of depression occurrence, Hamilton depression rating scale (HAMD) score, and adverse reactions were observed.
RESULTSThe 1-, 3-, and 6-month morbidity of PSD was 8%, 16%, and 34% in the experimental group, while they were 19.6%, 29.4%, and 54.9% in the control group. The occurrence rate was lower in the experimental group than in the control group. Besides, there was statistical difference in the 6-month occurrence rate between the two groups (chi2 = 4.465, P < 0.05). The average time of PSD occurrence was longer in the experimental group than in the control group (14.96 +/- 8.31 weeks vs. 9.36 +/- 6.06 weeks; t=6.762, P < 0.05). The HAMD score at the PSD occurrence was 11.96 +/- 2.14 in the experimental group, lower than that of the control group (14.57 +/- 4.24), showing statistical difference (t=5.641, P < 0.05).
CONCLUSIONWC was superior to the placebos in lowering the incidence of PSD, delaying the occurrence time of PSD, attenuating the depression degree of PSD, and had certain preventive effect on the incidence of PSD.

OBJECTIVETo screen a variety of Porphyromonas gingivalis (Pg) common outer membrane proteins with two-dimensional liquid phase fractionation (PF2D) and matrix-assisted laser desorption ionization time-of-flight/time-of-flight mass spectrometry (MALDI-TOF/TOF-MS) and provide candidate target antigen for the design of vaccines with cross protection against a variety of Pg.
METHODSThe outer membrane proteins of Pg301, PgATCC33277 and PgW83 were extracted through ultracentrifugation, and then they were separated by ProteomeLab PF2D protein fractionation system. After separation, the outer membrane proteins were obtained through comparison, and the primary structure of the proteins was identified by MALDI-TOF/TOF-MS and database.
RESULTSNinety-nine protein samples out of 3 strains of Pg were obtained after the high performance chromato focusing (HPCF) separation process. B7 fractions of 3 strains of Pg were separated by the reversed-phase high performance liquid chromatography (RP-HPCL) separation process. After comparison of peak and retention time of chromatogram, the 8 common protein peaks of 3 strains of Pg were confirmed. The protein samples were identified by MALDI-TOF/TOF-MS, and one of them was known protein arg-gingipain A.
CONCLUSIONSPF2D protein fractionation system is of good reproducibility and high resolution. A combination of PF2D and MALDI-TOF/TOF-MS can be used to identify the common outer membrane proteins of Pg.
