To establish a new method for identifying genus of Lilium by DNA barcoding technology, ITS, ITS2, psbA-trnH, matK and rbcL sequences were analyzed in term of variation of inter- and intra-species, barcoding gap, neighbor-joining tree to distinguish genus of Lilium based on 978 sequences from experimental and GenBank database, and identification efficiency was evaluated by Nearest distance and BLAST1 methods. The results showed that DNA barcoding could identify different species in genus of Lilium. ITS sequence performed higher identification efficiency, and had significant difference between intra- and inter-species. And NJ tree could also divide species into different clades. Results indicate that DNA barcoding can identify genus of Lilium accurately. ITS sequence can be the optimal barcode to identify species of Lilium.

Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma were widely used in strengthening spleen under different disease conditions, and were easily and often misused each other. Therefore, DNA barcode was used to distinguish Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from their adulterants to ensure the safe use. The sequence lengths of ITS2 of Atractylodes macrocephala, Atractylodis Rhizoma (A. lancea, A. japonica and A. coreana) were both 229 bp. Among the ITS2 sequences of A. macrocephala, only one G/C transversion was detected at site 98, and the average GC content was 69.42%. No variable site was detected in the ITS2 sequences of A. lancea. The maximum K2P intraspecific genetic distances of both A. japonica and A. coreana were 0.013. The maximum K2P intraspecific genetic distances of A. macrocephala, A. lancea, A. japonica and A. coreana were less than the minimum interspecific genetic distance of adulterants. The ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. DNA barcoding could be used as a fast and accurate identification method to distinguish Atractylodis Macrocephalae Rhizoma, Atractylodis Rhizoma, from their adulterants to ensure its safe use.

OBJECTIVE: To study the tongue tissue blood oxygen saturation measurement for evaluating tongue manifestation of blood stasis syndrome, and to explore its correlation with blood rheological disorder in a rat model of acute transient brain ischemia. METHODS: Twenty-eight SD rats were randomly divided into sham-operated group and ischemia group. Middle cerebral artery occlusion was induced by thread in rats of the ischemia group. Tongue tissue blood oxygen saturation, neurological severity score and the changes of blood viscosity, red blood cell deformity, thrombin time and fibrinogen in the rats were measured after 24-hour reperfusion. RESULTS: Blood viscosity and the content of fibrinogen in the ischemia group were significantly higher than those in the sham-operated group. Red blood cell deformity, thrombin time and tongue tissue blood oxygen saturation in the ischemia group were decreased as compared with the sham-operated group. There was a positive correlation between red blood cell deformity and tongue tissue blood oxygen saturation. CONCLUSION: Tongue tissue blood oxygen saturation is a good measurement for evaluating blood stasis in a rat model of focal cerebral ischemia, and this model can be used as a rat model of stroke with blood stasis syndrome.

Objective: To investigate the effect of taurine on learning and memory impairment, cytokines secretion in rats intrahippocampally injected with ?-amyloid (A?) 1-40. Methods: SD rats were randomly divided into control group, A? injected group, taurine (0.3g/kg?d, 0.6g/kg?d) groups. The rats were fed with taurine for 7 days, and then subjected to bilateral intrahippocampus injection of A?1-40 or vehicle. Two weeks later, all rats performed Morris water maze test. The contents of IL-6, TNF-? were checked by way of radio-immunity assay for hippocampus samples. Results: Compared with A?model group, the escape latency and distance were significantly reduced in taurine (0.6g/kg?d) group; the ratio of swimming distance in the target quadrant to that in the whole pool of the probe trial; the content of cytokines of IL-6 and TNF-?in hippocampus were reduced significantly. Conclusion: Taurine can effectively attenuate the cognitive dysfunction caused by A?1-40 in rats. The reduced cytokines content in hippocampus might contribute to this effect.

Objective: To observe the effect of electroacupuncture (EA) pretreatment on the protein expression of c-fos in fastigial nucleus (FN) and lateral hypothalamus area (LHA) in rats with acute myocardial ischemia-reperfusion injury (MIRI), and to explore the role and mechanism of FN and LHA in EA at the Heart Meridian fighting against acute MIRI reaction. Methods: Seventy Sprague-Dawley rats were randomly divided into a sham operation group, a model group, an EA-Heart Meridian group and an EA-Lung Meridian group, with 14 rats in each group; an LHA lesion plus EA-Heart Meridian group (LHA+EA-Heart Meridian group) and a FN lesion plus EA-Heart Meridian group (FN+EA-Heart Meridian group), with 7 rats in each group. Except the sham operation group, the left anterior descending branch of coronary artery was ligated to establish acute MIRI rat models in the other 5 groups. In the three groups with EA-Heart Meridian treatment, Shenmen (HT 7) and Tongli (HT 5) were selected; Taiyuan (LU 9) and Lieque (LU 7) were selected in the EA-Lung Meridian group. All the EA groups received EA stimulation prior to modeling, with 1 mA in current intensity and 2 Hz in frequency, 20 min each time, once a day for a total of 7 d. The sham operation group and the model group did not receive EA stimulation. The electrocardiogram was observed in the rats to analyze the ST-segment deviation and cardiac arrhythmia score. The expression of c-fos protein in FN and LHA was detected by immunohistochemistry method. Results: Compared with the sham operation group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in the FN and LHA increased significantly in the model group (all P<0.05). Compared with the model group, the ST-segment deviation, cardiac arrhythmia score and the expression of c-fos protein in FN and LHA decreased significantly in the EA-Heart Meridian group (all P<0.05). Compared with the EA-Heart Meridian group, the ST-segment deviation and cardiac arrhythmia score increased significantly in the EA-Lung Meridian group, LHA+EA-Heart Meridian group and FN+EA-Heart Meridian group (all P<0.05); the expression of c-fos in FN increased significantly in the EA-Lung Meridian group and LHA+EA-Heart Meridian group (both P<0.05); the expression of c-fos in LHA increased significantly in the EA-Lung Meridian group and FN+EA-Heart Meridian group (both P<0.05). Conclusion: FN and LHA are involved in the mechanism of EA at Heart Meridian to improve the acute MIRI reactions, and the cerebellum may participate in the improvement of cardiac function by EA through the cerebellum-hypothalamus projection.
