Clinical characteristics of five traditional Chinese medicine injections in treating heart failure based on Meta-analysis literature / 中国中药杂志

In this article, we analyze the clinical characteristics of five kinds of traditional Chinese medicine injections in treating heart failure based on Meta-analysis. A total of 24 Meta-analysis papers were included, which involved Shenfu Injection, Shenmai Injection, Shengmai Injection, Danhong Injection and Huangqi Injection. The numbers of literatures of Shenfu Injection, Shenmai Injection and Shengmai Injection are high than the other two injections. The efficiencies of these injections combined with Western medicine are higher than the Western medicine used alone. They can improve 6 minute walk test result, ejection fraction, the level of brain peptide sodium and so on. Shenfu Injection can also improve the living quality of patients' life, heart rate and other indicators. Shenfu Injection can be used for patients with Yin deficiency, while Shenmai Injection can be used for patients with Yin deficiency and Shengmai Injection can be used for patients with Qi and Yin deficiency. From this information, we can see that Western medicine combined with traditional Chinese medicine injections can significantly improve the clinical efficiency. These injections need to be used according to patients' symptom. In the present, as the quality of clinical research literature of traditional Chinese medicine injections is low, the efficiency and safety evaluation of Chinese medicine injections still requires higher level of clinical evidence.

The teacher-disciple tradition and secret teaching in Chinese medicine / 中国结合医学杂志

The ancient teacher-disciple tradition is regarded as one of the most celebrated practices within the Chinese medicine world. Such traditions of secrecy, private wisdom and honor are deeply rooted in the theories of Confucianism. This paper only explores the surface of this ancient culture, by investigating relevant popular ancient texts and common Chinese proverbs, as well as utilizing personal experiences, in order to reflect on how the ancient Chinese perceived such practices within their own society and how secret teaching was passed on from teacher to student, including the revelation of secret formulas and their importance and how that tradition differs from our modern-day perspectives. Various rare manuscripts from the author's personal library are employed in order to provide relative examples of the importance of secret knowledge, and how these secrets applied in the traditional healing.

Comparative study on effects of Xiaoyao Powder and its modified prescription on plasma metabolomics of rats with chronic immobilization stress / 中国结合医学杂志

<p><b>OBJECTIVE</b>To determine the changes in the levels of endogenous metabolites in rats with chronic immobilization stress (CIS) taking Xiaoyao Powder (XYP) and its modified prescription version, which lacks the volatile oils extracted from Herba Menthae.</p><p><b>METHODS</b>Twenty-four experimental male SD rats were randomly divided into 4 groups of 6 rats each: control, model, XYP-1 (containing volatile oils from Herba Menthae), and XYP-2 (lacking volatile oils). All rats except control group rats were subjected to CIS 3 h per day for 21 consecutive days. Groups XYP-1 and XYP-2 were given the extracted XYS with or without volatile oils (3.854 g/kg; suspended in distilled water) via gavage 1 h before CIS each day for 21 days. Rats were anesthetized using intraperitoneal injection of pentobarbital sodium (40 mg/kg) on the 22nd day. Observations were made using a Varian INOVA 600 MHz NMR spectrometer at 27 °C. Carr-Purcell-Meiboom-Gill (CPMG) and longitudinal eddy-delay (LED) were applied, resulting in spectra showing only the signals from micro- and macro-metabolites.</p><p><b>RESULTS</b>Compared to controls, rats subjected to CIS showed increased levels of plasma metabolites, such as acetic acid, choline, N-glycoprotein (NAC), saturated fatty acid, and blood sugars. Levels of low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), and unsaturated fatty acids were decreased. The biochemical effects of XYS were characterized by elevated levels of VLDL, LDL, threonine, methionine, and glutamic acid in plasma.</p><p><b>CONCLUSION</b>Some common and characteristic metabolites on the anti-CIS of XYP and its modified prescription were obtained. The metabolomics technology is a valuable tool and may be used to identify the specific metabolites and potential biomarkers of therapeutic effect of Chinese medicinal prescriptions.</p>

Expression of AMPA receptors and related protein in immobilization stressed rats and effect of Xiaoyaosan / 中国应用生理学杂志

<p><b>AIM</b>To observe protein expression changes of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor and related regulatory protein in the hippocampus and amygdala in chronic immobilization stressed rat and Xiaoyaosan's regulatory effect.</p><p><b>METHODS</b>Rats were tied 3 h per day to establish immobilization stress condition and treatment with Xiaoyaosan. After 7 days and 21 days stress, the protein expression of AMPA receptor subunit (GluR2/3), N-ethylmaleimide sensitive factor (NSF) and protein interacting with C-kinase 1 (PICK1) in hippocampus and amygdala were detected by using Western blot techniques.</p><p><b>RESULTS</b>The expression of GluR2/3, NSF in dentate gyrus (DG) and amygdala were markedly attenuated (P < 0.05) and PICK1 in CA1 region were significantly increased (P < 0.05) in 7 d immobilization stressed rats while 7 days xiaoyaosan treatment showed an effective regulatory result to PICK1's changes. Under 21 days immobilization stressed condition, the expression of GluR2/3, NSF in CA1 region showed an increasing trend, and GluR2/3 showed a markedly increase (P < 0.01), but showed an significantly decreased trend in amygdala, Xiaoyaosan showed an effective result to such changes above (P < 0.05). The expression of PICK1 showed increasing trend in amygdala and xiaoyaosan could lower its expression (P < 0.05).</p><p><b>CONCLUSION</b>There are different trends of the expression of AMPA receptor in repeat short-term stress versus chronic immobilization stress, and in hippocampal CA1 region versus amygdala. Xiaoyaosan has better regulation effect on the expression of AMPA receptors in the condition of chronic immobilization stress than those of repeat shortterm stress.</p>

Metabonomic study on the regulatory effect of xiaoyao powder on chronic immobilization stressed rats / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To provide a scientific basis for systematic research on the mechanism of chronic immobilization stress (CIS) induced metabolic network change in rats, through detecting the changes of endogenous metabolites in rats with CIS, treated or un-treated with Xiaoyao Powder (XYP), for determining the small molecule marker compound that closely associated with the metabonomical specificity of CIS and acting mechanism of XYP.</p><p><b>METHODS</b>Thirty-six experimental male SD rats were divided into 3 groups, the normal control group, the model group and the XYP group. And all the three groups were subdivided into two subgroups respectively on day 7 and day 21 of the experiment. The stress rat model of CIS was made by chronic restraining method for 3 h every day. Starting from the first day of modeling, XYP 3.854 g/kg in volume of 1 mL/100 g body weight was administered 1 h before restraining via gastrogavage to rats in the XYP group, while equal volume of distilled water was given to rats in the other two groups instead. Blood samples were collected on the 8 th day and 22 th day for detection in the following procedure: at 27 degrees C, 300 microL supernate of blood plasma was taken, calling the Carr-Purcell-Meiboom-Gill (CPMG) and longitudinal eddy-delay (LED) sequence respectively on a Fourier variable nuclear magnetic resonance (NMR) spectrometer, pre-saturated inhibition of the water peak was performed; free induction decay (FID) signals were transferred via 32 k Fourier transformation to gain one-dimensional NMR spectrogram; by taking TSP as the chemical migration reference peak, the segmental integral calculus (0.04 ppm per segment) was performed from 4.5 - 0.5 ppm (CPMG) and 6.0 - 0 ppm (LED) within the peak ranges in 1H spectra using the VNMR software; after normalization, centering and scaling were conducted on data, then used for pattern recognition of principal component analysis (PCA) using the SIMCA-P 10.0 software, or if necessary, the partial least squares discriminate analysis (PLS-DA) was performed.</p><p><b>RESULTS</b>(1) The metabolites in the model group were significantly different from those in the control group, suggesting that the animal model was successfully established with the metabolic network different to that of control. The model group and the XYP group could be differentiated from the control group by the differences of metabolites and metabolic networks between groups; XYP could intervene the metabolites or the metabolic path to cause changes in final metabolites. (2) The serum contents of lactic acid (1.4, 4.16), choline (3.24), N-acetylgalactosamine (NAC) and saturated fatty acids (1-3) increased, but unsaturated fatty acids (1.99,4-5), blood sugar (34), HDL (0.83), etc. reduced in the CIS rats. XYP showed obvious regulatory effects on final metabolites, causing decrease of lactic acid, choline, NAC, saturated fatty acids and blood sugar, and increase of unsaturated fatty acids, blood sugar, HDL, 3.44 ppm compound, etc.</p><p><b>CONCLUSIONS</b>The metabolic phenotype in CIS rats includes the increase of lactic acid, choline, NAC, saturated fatty acid, and the decrease of blood sugar contents, unsaturated fatty acid, HDL, 3.44 ppm compound, etc., these may be the markers of the metabolites. The final metabolites changes induced by CIS are primarily the lipid substances. XYP markedly regulates the contents of final metabolites, showing the regulatory effects on final metabolites, but what is the metabolite or metabolic pathways it interferes to alter the final metabolites should be confirmed by further studies.</p>
