microRNA (miRNA) is a class of endogenous non-coding small RNAs,they play an important role in post-transcriptional regulation of gene expression through combining the target mRNA that the target protein would not synthesis.The present studies have found that miRNA is involved in many kinds of physiological processes,as well as the pathological processes.The abnormal expression of miRNA in many diseases can be used in diagnosis,prognosis and treatment monitoring.But all of these studies depend on an ideal detection method of miRNA.A lot of detection methods of miRNA expression developed from qualitative analysis to quantitative analysis step by step and from single miRNA detection to high throughput screening in recent years.Various detection methods are improved constantly,the specificity and sensitivity has been improved at the same time,detection procedure become simple and practicable,detection time shorten considerably and cost also reduced ceaselessly,which make the application of miRNA in clinical possible.This review highlights the latest research progress of the common detection methods of miRNA.

Legal clinic education originating in the United States, aims at educating students on legal practical skills, and plays an positive role in cultivating students' ability of integrating theory with practice and training their various practical vocational skills. The present Chinese training mode of health law specialty does not perform very well in training students' practical ability, while legal clinic education can better make up for some deficiencies. Therefore, this paper learns from the experience of American universities in their legal clinic education, such as the particular division of specialties, the development of outside-school clinics, taking pre-training seriously, and the unique evaluation mechanism. Correspondingly, we explore to construct a set of reasonable legal clinic education system in health law specialty, including the orientation of legal clinics, the double training system inside and outside school, the construction of teaching staff and the establishment of evaluation mechanism.

OBJECTIVETo compare the anti-inflammatory and anti-nociceptive effects of the different water extracts which were prepared by regular decoction time or removing volatie oil and ethanol extracts which were prepared in different concentration ethanol of Xixin (the roots and rhizomes of Asarum heterotropoides var. mandshuricum), and then to investigate the anti-inflammatory and antinociceptive mechanisms.

METHODXylene-induced ICR mouse ear edema and hot plate test were utilized to evaluate the anti-inflammatory and anti-nociceptive effects of Xixin at different dose level (water extracts of regular decoction time or removing volatie oil at the dose of 0.8 g x kg(-1) and 1.6 g x kg(-1); 95% ethanol extracts at the dose of 0.91 g x kg(-1) and 1.82 g x kg(-1); 50% ethanol extracts at the dose of 0.76 g x kg(-1) and 1.52 g x kg(-1)). Xylene-induced adrenalectomized mouse ear edema model was used to study the anti-inflammatory mechanisms. To reveal the anti-nociceptive mechanisms, mice were pretreated with naloxone in the hot plate test.

RESULTThe water extracts significantly reduced the weight of ear edema as compared with control group. Inhibition ratios were 43.20% and 63.69% at the higher dose, respectively. The ethanol extracts also significantly reduced the weight of ear edema and the inhibition ratios were 61.86% and 52. 56% at the higher dose, respectively. Mice administered water extracts delayed the latency times in the hot plate test. The anti-nociceptive effects of water extracts peaked at 2.0 h after i.g. administration. The hot plate latency times were increased by 51.27%, 62.78%, 60.08% and 68.00% at peak time, respectively. Regular decoction time group showed more significant effects in both models. The anti-inflammatory effect of 95% ethanol extracts was similar to 50% ethanol extracts. The water extracts were not effective in reducing xylene-induced adrenalectomized mouse ear edema. The anti-nociceptive effect of water extracts was blocked by naloxone.

CONCLUSIONBoth the water extracts and ethanol extracts of Xixin showed considerable anti-inflammatory potency against xylene induced inflammation. The water extracts produced anti-nociception in thermal model. The water extracts prepared in regular decoction time showed better anti-inflammatory and anti-nociceptive effects. Both the 95% ethanol and 50% ethanol extracts showed similarly anti-inflammatory effects. The anti-inflammatory effect of water extracts related to adrenal gland. The anti-nociceptive effect of water extracts was involved in activating opioid receptor.

OBJECTIVETo assess the anti-nociception and anti-inflammation pharmacodynamics of Asarum heterotropoides var. mandshuricum and A. sieboldii.

METHODBoth the writhing test and hot plate test were conducted to assess the anti-nociceptive effect of Asarum and Xylene-induced mouse ear edema was conducted to assess the anti-inflammatory effect of Asarum.

RESULTTwelve samples of A. heterotropoides var. mandshuricum and A. sieboldii from different producing areas showed anti-nociceptive and anti-inflammatory effects. Specifically, 27% to 61% of the seven samples of A. heterotropoides var. mandshuricum showed anti-nociceptive effect and while 34% to 48% of A. sieboldi showed anti-nociceptive effect. The inflammatory inhibition rate of A. heterotropoides var. mandshuricum produced in six producing areas (38%-57%) is higher than that of A. heterotropoides var. mandshuricum produced in five producing areas (34%-48%). The same kind of Asarum produced in different areas showed significant differences. A. heterotropoides var. mandshuricum produced in Jilin province (38%-57%) showed better anti-nociceptive effect than sample produced in Heilongjiang province (34%) in writhing test. A. heterotropoides var. mandshuricum produced in Heilongjiang (43%) province showed a better anti-nociceptive effect than samples produced in Liaoning province (29%-36%) in hot plate test. A. sieboldii produced in Shaanxi province (47%-49%) showed a better anti-nociceptive effect than samples produced in Hubei province (40%) in writhing test. A. sieboldii produced in Shaanxi province (45%-59%) showed better anti-nociceptive effect than samples produced in Chongqing (40%) in hot plate test. A. heterotropoides var. mandshuricum produced in Jilin province (51%-63%) showed better anti-inflammatory effect than samples produced in Heilongjiang province (50%). In totality, the results from analysis of geoherbalism showed that famous-region A. heterotropoides var. mandshuricum and A. sieboldii had a better anti-nociception effect than Asarum produced in other producing areas, famous-region A. heterotropoides var. mandshuricum had a better effect than those produced in other producing areas in anti-inflammation. But famous-region A. sieboldii showed no obvious difference from those produced in other producing areas in anti-inflammation.

CONCLUSIONAll samples of Asarum showed anti-nociceptive and anti-inflammatory effects, but with significant differences among Asarum produced in different areas, indicating the eoherbalism to some extent.
