Objective To detect the atherosclerotic progression in low density lipoprotein receptor (LDL-R) gene knock-out mouse by ultrasound biomicroscopy(UBM) technique,and to monitor the intima media thickness (IMT) and changes in plague of aortic wall.Methods 10 male LDL-R gene knock-out mice of 16 weeks age and 10 LDL-R gene knock-out mice of 24 weeks age were in the experimental group,and 10 male C57BL/6 mice of 16 and 24 weeks age were in the control group.The shapes of their aortic roots,ascending aorta,aortic arch and CCA were detected by UBM,and the IMT at aortic root view and carotid artery bifurcation were measured,then the data were compared with histopathology of the corresponding vascular segments.Results The difference between the IMT of aortic root and carotid artery bifurcation of the 16 week old LDL-R mice and the control group of the same age had no statistical significance.The difference between the IMT of carotid artery bifurcation of the 24-week-old LDL R mice and the control group of the same age had no statistical significance.The IMT of aortic root thickened compared with control group of the same age(P ＜0.01).Conclusions The UBM technique can be used to detect the atherosclerotic progression in LDL-R gene knock-out mouse.

OBJECTIVE: To obtain the key identification information of Hippocampus barbouri (H. barbouri), investigate the pharmacognosy of the seahorse adulteration H. barbouri, using the combination of morphological and DNA barcoding technique. METHODS: Typical morphological characteristics of H. barbouri were studied based on the observations according to the previous reports and traditional pharmacognosy methods. Genomic DNAs of H. barbouri and other related seahorse species were extracted and the DNA barcoding genes of COI, 16S and ATP6 sequences were amplified and sequenced, respectively. In order to determine advantages of three barcodes for the identification of hippocampus, MEGA 7 was performed to analyze the intraspecific and interspecific distances and construct the NJ phylogenetic trees based on three different barcoding genes. RESULTS: The most typical distinguishing features of H. barbouri included the streak of the nose, five radial lines in the eyelid, and the long and short intervals of the tail thorns. The lengths of COI, 16S and ATP6 sequences were 649-650, 574 and 603 bp, respectively, with the maximum K2P intraspecific distances were 0.012, 0.003 and 0.003, respectively. The intraspecific distances of the three barcodes were far smaller than the corresponding minimum K2P interspecific distances of H. barbouri and other seven related seahorse species, existing an obvious barcoding gap. The NJ phylogenetic trees based on COI, 16S and ATP6 sequences showed that H. barbouri samples formed of a group indicating that H. barbouri could be distinguished from other seahorse species through the three DNA barcoding markers. In addition, H. barbouri showed close genetic relationship with H. histrix according to the NJ trees. Furthermore, the NJ tree structures of COI and ATP6 were more stable than that of 16S. CONCLUSION: The pharmacognostical investigation bases on the morphological identification and DNA barcodes obtained the key identification information of H. barbouri, providing the possibility for quick and accurate identification of this species. The COI, 16S and ATP6 barcoding genes can be used for further molecular identification markers for seahorse species. This study provides a new technical method for the development and quality control of hippocampus.

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.
