Analysis of medication regularity and pharmacodynamic characteristics of traditional Chinese medicine treatment in 444 severe cases of COVID-19 / 中国中药杂志

The coronavirus disease 2019(COVID-19) is developing rapidly and posing great threat to public health. There is no effective intervention for the severe patients, and their prognosis is poor. It is worth noting that in the fight against COVID-19, China has always put equal emphasis on both Chinese and Western medicine. Traditional Chinese medicine has played an important role in the whole process. It is of great significance to discuss the rules and characteristics of the prescription of traditional Chinese medicine in the treatment of COVID-19. In this study, information was collected from 444 severe COVID-19 patients who were admitted to a hospital designated to treat patients with severe COVID-19 in Wuhan before March 20, 2020. We collected traditional Chinese medicine prescriptions for patients with severe COVID-19, referred to Chinese Pharmacopoeia to standardize the names of traditional Chinese medicine, and extract the property, flavor and channel tropism of traditional Chinese medicines to analyze the rules of the prescriptions. IBM SPSS Modeler 18.0 software was used to conduct correlation analysis of traditional Chinese medicine. Effective traditional Chinese medicines against COVID-19 was identified by the TCMATCOV platform. In the end, 1 532 effective prescriptions were included. Among them, the high-frequency drugs are Poria, Astragali Radix, Pogostemonis Herba, Armeniacae Semen Amarum, Atractylodis Macrocephalae Rhizoma, Pinelliae Rhizoma, Glycyrrhizae Radix et Rhizoma, Magnoliae Officinalis Cortex, Ephedrae Herba, Cinna-momi Ramulus. Most of the drugs have the following functions: resolving dampness, replenishing deficiency, resolving phlegm, cough, and asthma. The core combinations are Pogostemonis Herba-Poria, Astragali Radix-Pogostemonis Herba-Poria, Amomi Fructus-Poria, Amomi Fructus-Pogostemonis Herba, Amomi Fructus-Astragali Radix. The majority of the medicines are with cold and warm properties, and the proportions are 41.03% and 38.46%, respectively. The medicinal flavors are mainly concentrated in sweet and bitter, and the proportions are 34.71% and 30.58%, respectively. The meridian of the drug is more into the lung, stomach and spleen, with lung accounting for 22.87%. From the analysis of high-frequency drugs to the core combinations, one can see that the main treatment principle for severe COVID-19 is to remove internal and external dampness, protect the spleen and stomach, remove evil energy, and support righteousness. TCMATCOV platform was used to calculate the network disturbances of the high-frequency drugs. It was found that the traditional Chinese medicine with a high disturbance score accounted for a high proportion of the classic anti-COVID-19 prescriptions used by clinicians. Among them, the drugs with top scores are Ephedrae Herba, Citri Reticulatae Pericarpium, Eupatorii Herba, Platycodonis Radix, Cinnamomi Ramulus, Astragali Radix, Magnoliae Officinalis Cortex, Atractylodis Macrocephalae Rhizoma, Pogostemonis Herba, Scutellariae Radix. After a further exploration of the action targets, it was showed that disease-specific factor TNF was the target of the above ten drugs, and traditional Chinese medicine can exert anti-inflammatory and immune-modulating effects.

<b>Comparison Traditional Medicine Educational Systems </b><b>in Japan and China </b> / 日本東洋医学雑誌

Traditional medicine educational systems in Japan and China were compared.<br>In Japan, Kampo medicine has been integrated into the core curriculum of undergraduate education in all medical colleges since 2001. Japanese university medical schools give 6,000 hours of western medical educa tion, and only 30 hours of Kampo education. In China at Traditional Chinese Medicine (TCM) universities, nearly half of teaching hours are devoted to TCM, and half to Western medicine. And even at medical univer sities that specialize in Western medicine, students will usually have 80 hours in TCM courses. Usually it takes five years to graduate. In Japan, Kampo education puts a special focus on the <i>Shang-han-lun </i>and <i>Jin-kui-yao lue </i>texts, which still influence daily practice. In China, on the other hand, TCM doctors rely on traditional theories of Chinese medicine such as the Yin-Yang theory, the Five Elements theory or relationships between meridians and organs. Kampo specialists have been increasing in recent years, although in China, the number of TCM doctors has been decreasing. However, better traditional medicine education would play a role in in creasing our inheritance of both in Japan and in China.

Different Effects and Peripheral Mechanism between Manual-acupuncture and Eiectroacupuncture on Mast Cell Function and Acupuncture Analgesia by Nerve Block in Acupionts / 针灸推拿医学（英文版）

Objective: To observe the effects of nerve block on MA and EA analgesia and mast cells degranulation in adjuvant arthritis rats in order to analyze the difference between the underlying peripheral mechanism of MA and EA analgesia. Methods: Zusanli (ST 36) was chosen as the acupuncturing point on adjuvant arthritis rats. Eighty SD rats were randomized into 10 groups, including control, model, normal+Lido, EA, Lido+EA, DLido+ZEA, Xlido+ZEA, MA, Lido+MA, Dlido+ZMA groups, with 8 rats in each group. Paw Withdraw Latencies and mast cells degranulation ratios were recorded and computed. Results: Compared with model group, the pain threshold (PT) and mast cells degranulation ratios of EA and MA groups were obviously increased (P<0.05 or P<0.01). The analgesia effects of both MA and EA were obviously attenuated after nerve block by pretreated with Lidocaine hydrochloride at the acupuncturing point or at the acupiont of proximal end in the same neural stem while they were not by the same manipulations at the acupoint of distal end. Degranulation ratios of mast cells caused by MA or EA were not obviously affected by nerve block. Conclusion: The effective signal of nerve conduction of MA analgesia is generated after the degranulation of mast cells in the process of acupoints activation or needle sense and it is the direct cause of generation of nerve signal. In the condition of EA, the acupoints activation is caused by the stimulation of electric signal on nerve receptor while the degranulation of mast cells is concomitant or feedback effect.

Telomeres,telomerases and idopathic pulmonary fibrosis / 中国病理生理杂志

Idopathic pulmonary fibrosis (IPF),with unknown pathogeny,is a interstitial lung disease. The pathological features are diffuse epithelial-cell lesion and excessive extracellular matrix deposition. Many investigators consider alveolar epithelial cells impairment and abnormal activation,fibroblast proliferation and myofibroblast differentiation as causes,resulting in excessive extracellular matrix disorganization of lung. Recently,it is believed that telomeres and telomerases might play a role in regulating the capacity of fibroblast proliferation and aberrant epithelial repair in IPF. The aim of this article is to review the telomeres,telomerases and their relationship with the idopathic pulmonary fibrosis,furthmore,to identify the etiology and pathogenesis of the idopathic pulmonary fibrosis and provide the study measure for establishing an effective treatment.
