Translational Chinese Medicine: A Way for Development of Traditional Chinese Medicine  [PDF]
Xuegang Sun, Donglan Lin, Weikang Wu, Zhiping Lv
Chinese Medicine (CM) , 2011, DOI: 10.4236/cm.2011.24029
Abstract: Translational Chinese medicine is one of the latest developing fields in traditional Chinese medicine. In this paper, we discuss the “3 w” namely, “what is”, “why to advance”, “how to carry out” and the significance of translational Chinese medicine. To overcome the innate drawbacks of traditional Chinese medicine (TCM), the basic theory of TCM had better be refreshed. The safety and efficacy of classic formulae and therapy experience of TCM should be evaluated based on strict quality control and reaffirmed with evidence based medicine. The significance of translational Chinese medicine is to transform Chinese medicine into a balanced, personalized medicine with sound safety, good efficacy and strict quality control.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.78.82
Abstract: Caveolins have important roles in the organization of detergent-insoluble lipid rafts, trafficking of cholesterol and anchoring of signaling molecules. In this study, the expression patterns of Caveolin-1 (Cav-1), Caveolin-2 (Cav-2) and Caveolin 3 (Cav-3) genes were investigated in the longissimus dorsi muscle and back subcutaneous fat of Berkshire and Yacha pigs at the age of 6 months using quantitative real-time PCR. The results showed that Cav-1 and -2 mRNA were abundantly expressed in back subcutaneous fat. The expression patterns of Cav-1 and -2 were similar in the two pig breeds. The expression levels in the back subcutaneous fat were significantly higher in Yacha pigs than in Berkshire pigs (p<0.01). Cav-3 was expressed predominantly in the longissimus dorsi muscle and the Berkshire pig had higher Cav-3 mRNA levels compared with the Yacha pig (p<0.01). These results indicate that the mRNAs of Cav family genes exhibit specific expression changes between Berkshire and Yacha pigs. The data contributes to the elucidation of the relationship between meat quality and Cav family genes expression and provides a basis for further study on the mutual regulation mechanism of Cav family genes.

Tao Li, Zhiping Wang
Surgical Science (SS) , 2013, DOI: 10.4236/ss.2013.41015

Prostate cancer (PC) is one of the most common causes of cancer-related death in the world among old men. Radical prostatectomy (RP) is the most common surgical procedure in treatments. However, the complications after RRP always confuse surgeons. Urinary incontinence, impotence, erectile dysfunction frequently have effects on the quality of life after RP on patients occurred PC. Inguinal hernias (IHs) after RP is the most common complication, especially indirect hernias. Thus, patients occurred post-IH are frequently performed secondary surgery. In recent years, urologists have explored different surgical techniques, managements, and preoperationly detections to prevent the development of IH postoperationly. However, the precise mechanism of this procedure occurred is unclear till now. Some retrospective studies have been performed to explore the occurence of IH post-RRP and prophylactic techniques to prevent or decrease IH occurred after RRP. Disappointingly, there is no one efficient and precise method influenced this procedure occurred. We reviewed recent studies about IH after RP through different approaches to evaluate the development of this procedure.

A New Class of Time-Consistent Dynamic Risk Measures and its Application  [PDF]
Rui Gao, Zhiping Chen
Technology and Investment (TI) , 2013, DOI: 10.4236/ti.2013.41B008
Abstract: We construct a new time consistent dynamic convex cash-subadditive risk measure in this paper. Different from exist-ing measures, both potential loss and volatility of risky objects are considered. Based on a one-period measure that dis-torts financial values, punishes downside risk yet rewards upside potential, a dynamic time consistent version is con-structed recursively through a modified translation property. We then establish a portfolio selection model and give its optimal condition.
Synthesis of High-Stability Acidic β/Al-MCM-41 and the Catalytic Performance for the Esterification of Oleic Acid  [PDF]
Zhiping Wang, Shitao Yu
Advances in Chemical Engineering and Science (ACES) , 2016, DOI: 10.4236/aces.2016.64031
Abstract: β/Al-MCM-41 molecular sieve was synthesized and used to catalyze the esterification of oleic acid with short chain alcohols such as methanol, ethanol, isopropanol and isobutanol to obtain biodiesel. The results indicated that β/Al-MCM-41 exhibited the excellent catalytic activity and stability, which was obviously superior to traditional Al-MCM-41. The relationship between acidity and catalytic activity was in detail examined by NH3-TPD and Py-FTIR. Moreover, the kinetics of esterification of oleic acid with methanol showed that the average reaction order n was 1.97 and that activation energy was 50.01 kJ/mol.

Abstract: 摘要: 开发过程中因受应力压实效应和基质解吸收缩效应的共同影响,导致煤储层渗透率发生复杂的变化。目前,已有诸多学者建立一系列的煤储层渗透率动态模型。然而,对欠饱和煤层气藏开发过程中的不同生产阶段,何种效应对煤储层渗透率起主导作用仍未达成共识。本研究在总结已有的渗透率变化模型的基础上,分析欠饱和煤层气藏开发过程中的降压解吸特征、有效应力效应、基质收缩效应和克林肯伯格效应,并对现有的渗透率模型进行改进与对比分析,以达到定量分析欠饱和煤层气藏储层渗透率变化规律的目的,最后通过鄂尔多斯东南缘韩城煤层气田实例分析煤储层渗透率动态变化特征及其主控因素。结果表明欠饱和煤层气藏开发过程中渗透率动态变化特征可以临界解吸压力划分为两个阶段,前一阶段仅为有效应力效应作用阶段,后一阶段则受有效应力效应、基质收缩效应和克林肯伯格效应影响,且后两种效应随着储层压力的降低而进一步显现。对比分析显示SD改进模型在描述欠饱和煤层气藏渗透率动态变化上优于PM改进模型。因此,借助SD改进模型对韩城煤层气井进行实例计算,分析结果显示煤储层渗透率改善效果依次为3#>11#>5#,区内煤储层渗透率改善效果取决于含气饱和度,而渗透率应力伤害受控于地解压差。
Abstract: Coal reservoir permeability is under very complicated change due to the combination of the effective stress effect and matrix shrinkage effect during the depletion of reservoir pressure. Nowadays a large number of models have been established to describe permeability variation with the depletion of reservoir pressure. However, no attempt has been made to draw enough attention to the difference of the effect of various factors on permeability variation in different production stages of unsaturated coalbed methane (CBM) reservoirs. This paper summaries the existing and common permeability models, and determines the relationship among various effects (effective stress effect, matrix shrinkage effect and Klinkenberg effect) and desorption characteristics of the recovery of unsaturated CBM reservoirs, then establishes two improved models to describe quantificationally permeability variation by improving the existing models, and finally discusses influence factors on permeability variation with a case study of Hancheng CBM field in Ordos Basin. Results show that the permeability variation during the recovery of unsaturated CBM reservoirs can be divided into two stages: the first one is that the permeability variation is only affected by the effective stress effect, and the second is that the permeability variation is affected by the combination of effective stress effect, matrix shrinkage effect and Klinkenberg effect. In the second stage, matrix shrinkage effect and Klinkenberg effect play much more significant role than effective stress effect, leading to the increase of permeability with depletion of reservoir pressure. A comparative study of the improved models indicates that the improved SD model is more sensitive to various parameters than the improved PM model and the improved models, and can describe dynamic permeability variation more exactly than the original ones. Thus, the case study, by improved SD model, on Hancheng CBM field shows that the increase in coal reservoir permeability is determined by gas saturation, and

Liver cirrhosis portal hypertension patients to reduce the number of blood cells are common in clinical, and often affect the prognosis. This paper discusses cirrhotic portal hypertension patients complicated by the reason of the decrease in the number of peripheral blood cells and what is the clinical significance of these reasons so as to provide theoretical support for the choice of treatment. Splenomegaly and hypersplenism caused should be the main reason for reducing the number of blood cells, but not all, other reasons are alcohol and virus inhibition of bone marrow, liver function impairment, autoimmune damage and loss of blood, etc. If it is a function of the spleen hyperfunction caused by blood cells decreases, blood should rise to normal after splenectomy, or consider other reason or there are other reasons at the same time.

Selection of Macroeconomic Forecasting Models: One Size Fits All?  [PDF]
Yunyun Lv
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.74048
Abstract: The main distinction between this paper and traditional approach is the assumption that variables affect the economy through different horizons. Under this alternative hypothesis, a variable considered as an unimportant detail from a short-horizon perspective may become an essential factor in a long-horizon standpoint, this paper, therefore, suggests selecting variables specific to the horizon. My findings confirm that a model that allows the variables particular to the horizon has a lower Schwarz Bayesian Information Criterion (SBIC) value than a model that does not. My outcomes also show that the vector autoregression (VAR) model in general forecasts poorly compared with my approach. Likewise, I contribute to the literature by setting predictions equal to the sample mean as a benchmark and showing that the out-of-sample forecasts of the VAR model with lag length higher than one fail to outperform the sample mean. Additionally, I select principal components derived from 190 different time series to forecast a time series as the time horizon varies. Again, the results show that some of the principal components may be more important at some horizons than at others, thus I suggest selecting the principal components in a factor-augmented VAR (FAVAR) model specific to the horizon. According to above results, I conclude that long-horizon and deep-rooted economic problems cannot be fixed with short-horizon and surface-level interventions. I also reach my argument via simulation.
