RESUMO
Alternative splicing (AS) is a universal post-transcriptional regulation process in cells, and increasing evidences have validated its crucial role in tumors. We collected AS event, gene expression, and clinical data of 178 AML patients from The Cancer Genome Atlas (TCGA) project. More than 1,000 AS events were found associated with overall survival (OS), and alternate promoter (AP) events were the most significant. The expression of the KIAA0930 transcript was the most significantly different AS event selected from AP events and significantly correlated with the expression of the splicing factor (SF) polypyrimidine tract-binding protein 1 (PTBP1). Then, the roles of PTBP1 on AS of the KIAA0930 and the proliferation of AML cells were confirmed. KIAA0930 variant 1 (KIAA0930-1) was upregulated and variant 2 (KIAA0930-2) downregulated with knockdown PTBP1 expression of AML cells by specific shRNA. A low level of PTBP1 can decrease the proliferation ability of AML cells. In conclusion, the results showed that PTBP1 might be a potential target for AML therapy.

Parkinson's disease is a common degenerative disease of central nervous system. Exercise for Parkinson's disease includes Taiji Quan, treadmill, dance and balance training, etc. Taiji Quan exercise is mainly for balance function, and treadmill training for gait obstacles. Dance can improve not only balance and gait, but also cognition and emotion. The possible molecular mechanism may involve to adjust the content of dopaminergic neurons in the nigrostatin, increase the content of non-dopaminergic transmitters, increase brain-derived neurotrophic factors, promote the plasticity of nerve cells, reduce oxidative stress, enhance mitochondrial activity, and activate the immune system, etc., to slow the degeneration of dopaminergic neurons and improve the symptoms of Parkinson's disease.
RESUMO
A UPLC method has been developed for simultaneous determination of nine furanocoumarins of Angelica dahurics,and was used for quality evaluation of A. dahurica from different habitats. ACQUITY UPLC BEH C18 chromatographic column was employed,the separation was performed with the mobile phase consisting of acetonitrile and water,and the detection wavelength was set at254 nm. This method was used to simultaneously determine the content of xanthotoxol,oxypeucedaninhydrate,byak-angelicin,psoralen,xanthotoxin,bergapten,oxypeucedanin,imperatorin and isoimperatorin in A. dahurica from different habitats. Then,the further quality assessment of the drug was carried out by similarity evaluation,cluster analysis( CA),principal component analysis( PCA),and orthogonal partial least squares discriminant analysis( OPLS-DA). The content order of measured furanocoumarins from high to low was: oxypeucedanin>imperatorin>isoimperatorin>oxypeucedaninhydrate>bergapten>byak-angelicin>xanthotoxin>xanthotoxol>psoralen,with the mean content 2. 844,1. 277,0. 649 2,0. 216 2,0. 129 8,0. 062 68,0. 052 68,0. 019 30,0. 018 19 mg·g-1,respectively. There were difference between the batches of the drug,and the quality was influenced by smouldering sulphur based on the results of chemical pattern recognition and content determination. Finally,six active ingredients were recognized as the quality makers using OPLS-DA method. The validated UPLC fingerprint combined with chemical pattern recognition method can be used in the quality control and evaluation of A. dahurica.

Objective:To investigate the effects of electroacupuncture on blood-brain barrier to promote intake of drugs into brain of SAMP8 mice. Methods:The male SAMP8 mice (30-week-old) were randomly divided into model group (n = 7), drug group (n = 7), acupuncture group (n = 7) and combined group (n = 7). Other SAMR1 mice were as control group (n = 7). The acupuncture group and the combined group accepted electroacupuncture at Baihui (DU20) and Yintang (EX-HN3), the drug group and the combined group accepted Donepezil, for four weeks. They were observed hippocampus tight junction (TJ) under transmission electron microscope. The activities of acetylcholinesterase (AChE) in hippocampus were detected with immunohistochemistry. The mRNA expression of ZO-1, Claudin-5 and Occludin was detected with real-time quantitative polymerase chain reaction. Results:TJ and basement membrane in the control group, the acupuncture group and the combined group were better than those in the model group and the drug group. AChE was the most in the combined group, and then the drug group and the control group, the acupuncture group and the model group (P < 0.001). The expression of mRNA of ZO-1, Claudin-5 and Occludin was more in the acupuncture group and the combined group than in the drug group (P < 0.01). Conclusion:Electroacupuncture could ameliorate blood-brain barrier disruption and promote drug to enter the brain in SAMP8 mice, which may relate to the adjustion of ZO-1, Claudin-5 and Occludin.
RESUMO
<p><b>Background</b>The effectiveness of the combination of electroacupuncture (EA) and behavioral training (BT) for mid/advanced cerebral infarction (M/ACI) and related mechanisms remains unclear. This study aimed to investigate the combined effects on the learning-memory ability and event-related potential P300 in rats with M/ACI.</p><p><b>Methods</b>Eighty rats with M/ACI were divided into Group Model (M), Group EA, Group BT, and Group EA-BT (n = 20) according to the random number with five healthy rats in Group Control (CON). On the 6 week after modeling, EA, BT, and EA-BT were given to Group EA, Group BT, and Group EA-BT, respectively, whereas Group M and Group CON were not given any intervention. Y-maze test and P300 were recorded before and after the intervention.</p><p><b>Results</b>After intervention, the P300 latency was lower and the amplitude was higher in the Group EA-BT, Group EA, and Group BT than before (for latency, t = -7.638, -4.334, and -5.916; for amplitude, t = 8.125, 3.846, and 5.238; P < 0.01), with Group EA-BT superior to Group EA (for latency, t = -3.708; for amplitude, t = 3.653; P < 0.01) and Group BT (for latency, t = -2.067; for amplitude, t = 2.816; P < 0.05), with no significant difference between Group BT and EA (for latency, t = -1.439; for amplitude, t = 1.075; P > 0.05). While the performances of Y-maze tests in the Group EA-BT, Group EA, and Group BT were all better than before (t = 10.359, 4.520, and 7.791, P < 0.01), with Group EA-BT better than Group EA (t = 5.627, P < 0.01) and Group BT (t = 2.913, P < 0.01) respectively, and Group BT better than Group EA (t = 2.912, P < 0.01).</p><p><b>Conclusion</b>EA or BT can affect P300 in rats with M/ACI, and the combination of these two methods can significantly improve the learning-memory ability.</p>

A systematic analysis was made on the correlation between acupoints and pathological changes of the zang-fu organs through reviewing of literatures in the database of CNKI from 1959--2011 and the database of Pubmed of the past 10 years. The result showed that specificity was found on the pathological changes of zang-fu organs when acupoints were stimulated. And the pathological changes of the internal organs can be perceived from acupoints on the correspondent meridians, mainly regarding the heart, the stomach, the intestines, the lung and the liver, etc. And most of the researches focused on the correlation between acupoints of the heat meridian and the heart. It was also discovered that a lot of acupoints on various meridians could manifest the pathological changes of the same organ. Different effects of the same acupoints on different times could be found on the same internal organ. Therefore, it is concluded that there is a relative specificity between acupoints and pathological changes of the zang-fu organs. However, it is worth to study the regularity of specificity further.

@#ObjectiveTo observe the effect of dressing and moxibustion-pretreatment on the local joint swelling and stress hormone in hypothalami of rats with adjuvant arthritis (AA) at early and secondary stages.MethodsForty Wistar rats were randomly divided into 5 groups: normal group, early and secondary model groups, early and secondary pre-dressing and moxibustion (PDM) groups. The dressing with Chinese herb and moxibustion was stuck on Dazhui point (GV14) before the AA model established. The effects of dressing and moxibustion-pretreatment on the feet swelling and corticotropin-releasing-hormone (CRH), beta-endorphin (β-EP) and neuropeptide-Y (NPY) in hypothalami were observed.ResultsThe right feet swelling rate at early and secondary stages obviously increased after modeling ( P<0.01), and it became lower in early and secondary PDM groups than in model groups at the same phases ( P<0.05~0.01). The level of hypothalamic CRH was higher after modeling ( P<0.05~0.01), compared with early model group, it had a tendency to going down in early PDM group, moreover, in secondary PDM group the level was similar with the normal group. The level of hypothalamic β-EP increased significantly in early model group ( P<0.01), and lightly changed in secondary model group, it decreased in early PDM group but increased in secondary PDM group, compared with model groups at the same stages ( P<0.05). The level of hypothalamic NPY increased significantly after modeling, and it declined in the secondary PDM group ( P<0.05).ConclusionDressing and moxibustion-pretreatment can relief feet swelling of AA rats, which may be related with its regulative effect on the level of hypothalamic CRH, β-EP and NPY.

Simultaneously it down-regulated the expression of TF-mRNA. (2) PNS could partially inhibit the NB4 cell proliferation. (3) PNS could raise the NBT reducing capability of NB4 cells (P < 0.05). And morphological examination showed the differentiating tendency of monocyte and macrophage.</p><p><b>CONCLUSION</b>PNS could reduce the procoagulant activity and TF-mRNA expression in NB4 cells, and partially induce the differentiation of NB4 cells, therefore, it is hopeful to be a new anti-coagulant agent.</p>
