Journal of Zhejiang Chinese Medical University 2015;(7):534-536
[Objectives]To extract Yang Lishan’s description of latent evils ,summarize his arguments, and provide reference for exploring his academic ideology further. [Methods] Use the literature methodology, take“latent evils”and“pestilential pathogen”as keywords, retrieve the related description in Yang Lishan’s book, summarize his main opinions on latent evils. [Results] Yang Lishan wholly refused the theory of latent cold evil turning into pathogenic warm, and he believed that the cause of latent evils is pestilential pathogen, thereby distinguishes warm disease from exogenous febrile disease on etiology level. He described the disease’s quality, afferent pathway, hiding spot, the way out, therapeutic method, prescription and recuperation in details, which are mature enough to form a complete theoretical system. The prescription Sheng Jiang Powder represents experiment with the thought of treating pestilential pathogen with drugs and special medicine for special disease, which makes the etiology of pestilential pathogen to have real directive value. [Conclusion] Yang Lishan’s theory of latent evils has implications in treatment and prevention of epidemic diseases.

Interferon-tau (IFN-tau) is a newly discovered IFN of type I. It was originally found for its role as a pregnancy recognition hormone in ruminant animals such as sheep and cows. Like the other type I IFNs, IFN-tau have the same biological activities including antiviral, antiproliferative and immunomodulatory effects. In order to clearly identify the function of IFN-tau, the coding sequence of IFN-tau was amplified by PCR from IFN-tau cDNA, this fragment digested by EcoR I and BamH I and was inserted into pBV220 to form the recombinant plasmid pBV220/IFN-tau which was then transformed into E.coli BL21. It was found that pBV220/IFN-tau was highly expressed as inclusion body in BL21. Next, the expressed protein was purified on S-100 High Resolution and the purified product was confirmed by amino acid sequence analysis. Moreover, the standard antiviral activity test indicated that the activity of IFN-tau was about 2.09?106IU/ml.

BACKGROUND:Based on the blood and urine biochemical changes in different intensities and types of exercise, this research describes the impact of exercise on bone metabolism. Meantime, these biochemical indexes also show a method of marking physiological differences of certain individuals, and also reflect the impact of exercise on bone. These can be regarded as a monitoring index of bone growth and metabolism. OBJECTIVE:To study exercise effect from the biochemical indicators in bone metebolism, and make a further discussion about its influence on bone formation and bone resorption. METHODS:Databases of CNKI and PubMed were retrieved by computer with key words of “exercise; bone metabolism; biochemical indicators” in Chinese and English, respectively, by screening titles and abstracts to search papers related to exercise effects on the blood and urine biochemical indicators. Totaly 236 papers were initialy found, and only 38 papers were included in result analysis. RESULTS AND CONCLUSION: Low-intensity exercise shows less effect on the bone, but excessive exercise is harmful to the bone that can cause stress fractures. What’s worse, it causes a lack of female hormone and reduce bone mass. Exercise can alter the blood and urine biochemical indicators in aspects of types of exercise and intensities. Only the exercise at appropriate intensity makes positive effects on bone formation and resorption, and assists bone mineral density and bone biomechanical indicators to develop exercise prescription and arrange rehabilitation exercises. MechanismS of bone turnover need further discussion at the celular level.

Objective To evaluate the diagnostic accuracy of transcranial doppler(TCD)as an additional screening tool for intracranial arterial steno-occlusive disease in patients with acute ischaemic stroke(AIS)by comparing with the computed tomography angiography(CTA). Methods Two hundred and twenty-four consecutive patients who were hospitalized within 7 days of the onset of symptoms and fulfilled the criteria for the clinical di-agnosis of AIS between May 2013 and May 2014 were enrolled for the study. Among the 224 patients,there were 118 males and 106 females with an average age of 61.2±12.6 years. High-resolution brain CTA was performed after completion of TCD. Results There was slight distinction of the diag-nostic accuracy of TCD for different arteries. TCD demonstrated the most accurate diagnosis for carotid artery vascular system,with a sensitivity of 96.19%and specificity of 98.60%. For the vertebrobasilar vascular system,TCD diagnosis showed a sensitivity of 71.11%and specificity of 94.31%. TCD findings were complementary to the CTA results(real-time embolization,collateral flow patterns and steal phenomenon). Conclusion TCD shows a high diagnostic accuracy comparing to CTA in evaluating intracranial and extracranial arterial stenosis in patients with AIS,especially for the carotid artery vascular system analysis within a short time interval. TCD can also provide additional real-time dynamic findings complementary to the information provided by CTA.
