GAO Hong's clinical experience in treatment of tic disorder with acupuncture technique of cultivating the primary and regulating the mind / 中国针灸

The paper introduces the clinical experience of GAO Hong in treatment of tic disorder. GAO Hong believes that tic disorder results from the primary qi deficiency and mind disturbance. Acupuncture for cultivating the primary and regulating the mind is proposed specially for tic disorder. This acupuncture technique focuses on harmonizing and regulating governor vessel and conception vessel. In clinical practice, the conception vessel acupoints on the abdomen and the governor vessel acupoints on the head are selected particularly, e.g. Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6) and Guanyuan (CV 4) on the abdomen; Baihui (GV 20), Shenting (GV 24), Benshen (GB 13) and Yintang (GV 24+) on the head. The needling sequence and the insertion depth are emphasized, which affect the curative effect and GV 20 is generally punctured first. Besides, considering to the type of disorder and the affected site, tic disorder is treated in view of both syndrome/pattern differentiation and symptom differentiation.

Chemical Composition Analysis of Antibacterial and Anti-inflammatory Functions of Volatile Oils from Pelargonium graveolens L'Herit / 中国生物化学与分子生物学报

The components of volatile oils are generally complex, and they often have the functions of divergent dissolving surface, insecticidal and antibacterial. However, there are few reports on bacteriostasis, anti-inflammation and antioxidation roles of volatile oils of Pelargonium graveolens L'Herit. The volatile oil of Pelargonium graveolens L’Herit. was extracted by steam distillation, and GC-MS and peak area normalization analysis showed that it mainly contained 30 compounds, and the identified components accounted for 90.26% of the total peak area. The volatile oil of Pelargonium graveolens L'Herit. has a certain inhibitory effect on Candida albicans and Staphylococcus aureus, especially on Candida albicans. The diameter of the bacteriostatic zone is 15.55±1.53 mm by using the oxford cup method. Dexamethasone and low, middle and high doses of volatile oils of Pelargonium graveolens L'Herit. were given after the RAW264. 7 cell inflammatory model and was induced by lipopolysaccharide (LPS = 10.0 μg/mL). ELISA assays showed that it could effectively reduce the expression of IL-1β and TNF-α in inflammatory cells, and the effect of high doses was similar to that of IL-1β and TNF-α in the dexamethasone group. GC-MS was successfully used to determine and identify the chemical constituents of volatile oils from Pelargonium graveolens L'Herit. in this study. We show that the volatile oil of Pelargonium graveolens L'Herit. had certain bacteriostatic activity and effectively reduces the secretion of IL-1β and TNF-α by inflammatory cells. It provides an experimental basis for the development and utilization of volatile oils from Pelargonium graveolens L'Herit.

A Reflection on the 2017 Nobel Prize for Physiology and Chinese Medicine / 中国结合医学杂志

Research on the molecular mechanisms controlling circadian rhythm in Western medicine is comparable to the study of a day-night rhythm in Chinese medicine (CM), as also focus on the same life phenomenon. By comparing the two, this paper elaborates on the differences between them in their respective issues of consciousness, ways of thinking, research methods and research results. Relatively speaking, Nobel Prize research has a stronger sense of the problems and concerns about the essence of "what", while CM focuses on "how a thing functions". The former mainly adopts experimental and mathematical methods, while the latter primarily depends on observation and understanding. The natural philosophy and natural science eventually lead to the results and the inevitable, quantitative and qualitative differences. Research on the life rhythm in CM should be proposed, scientific problems should be fully grasped, and research should be carried out with the aid of multidisciplinary new knowledge and new achievements through cross-disciplinary studies. On the basis of clinical epidemiological research and experimental research, a systematic review should be made of the human physiology of CM and the pathological rhythm model to explore the regulatory mechanism of time rhythm and create a new theory of time medicine.

Interleukin-1 inhibits Sox9 and collagen type II expression via nuclear factor-kappaB in the cultured human intervertebral disc cells / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The most significant biological change in intervertebral disc degeneration is the decrease of chondrocyte specific gene and protein expression of Sox9 and collagen type II. Interleukin-1 (IL-1) is not expressed in the normal intervertebral disc tissue but increases in the degenerated intervertebral disc tissue. This suggests that IL-1 may play a role in regulation of the expression of Sox9 and collagen type II.</p><p><b>METHODS</b>Human intervertebral disc cells were isolated and cultured. Sox9 and collagen type II expression during treatment with IL-1, with or without the nuclear factor-kappaB (NF-kappaB) activity inhibitor curcumin, were detected by using reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting, and the activity of the NF-kappaB signaling pathway was detected by the electrophoretic mobility shift assay (EMSA).</p><p><b>RESULTS</b>IL-1 lowered the mRNA level and protein expression of Sox9 and collagen type II in the cultured intervertebral disc cells in a dose dependent manner (P < 0.05), and this effect was attenuated by curcumin. Curcumin alone had no effect on Sox9 and collagen type II expression (P > 0.05). IL-1 at concentrations of 0.1 ng/ml, 1 ng/ml and 10 ng/ml could stimulate the activity of NF-kappaB in the intervertebral disc cells in a dose dependent manner (P < 0.05) that was inhibited by curcumin.</p><p><b>CONCLUSIONS</b>We demonstrated the previously unknown function of IL-1 in inhibiting Sox9 and collagen type II via NF-kappaB in the intervertebral disc cells. This inhibition can be attenuated by curcumin, which is an effective NF-kappaB activity inhibitor.</p>
