Experience in Treatment of COVID-19 by Elimination of Pathogens Through Purgation and Diuresis / 中国实验方剂学杂志

Coronavirus disease-2019 (COVID-19) outbreaks were spreading rapidly around the world in early 2020. This disease is within the category of "damp epidemic" and "damp toxin epidemic" in traditional Chinese medicine, with lung and spleen as the lesion focuses, while dampness and toxin as especially prominent properties. Through clinical observation, we found that dampness would often transform into damp heat during the development and evolution of the disease, and the "triple energizer" treatment was an important therapeutic method, eliminating pathogens through purgation and diuresis: for those with damp-heat accumulation toxin diffused to the triple energizer, we could use Ganlu Xiaodudan as primary prescription, which can spread the upper part, smooth the middle part and infiltrate the lower part, so as to provide a way out for the pathogenic factors and regulate Qi movement. For those with damp-heat in Shaoyang channel, we could use Haoqin Qingdantang to clear heat and promote diuresis, harmonize Shaoyang, eliminate damp-heat and epidemic pathogenic factor. For those with pathogen hidden in membrane source dampness trapping and hidden heat, we could use Dayuanyin to eliminate pathogens between interior and exterior parts, and regulate Qi movement. At the same time we shared three typical cases treated in Wuhan, and conducted an in-depth analysis in this study. Clinically, the method of elimination of pathogens through purgation and diuresis is mainly used in the early and middle stage of this disease. When the disease is still located in Qi system, it also can be applied to mild, ordinary patients and severe patients that have accurate syndrome differentiation. In such cases, it can effectively improve symptoms, reduce pathogenic toxin, truncate and reverse the course of disease, give way to pathogen, and avoid disease aggravating.

Analysis of Medical Cases of Coronavirus Disease-2019 Treated with Haoqin Qingdantang / 中国实验方剂学杂志

Coronavirus disease-2019 (COVID-19) is highly contagious. In the early stages of the disease, the symptoms of coldness, dampness and depression in the lungs often appear, including fever, fatigue, soreness, dry cough, poor appetite, and white greasy tongue coating. During the development of the disease, the damp toxin epidemic often enters the inner and generates heat, and the damp heat epidemic toxin blocks pleurodiaphragmatic sites, the triple energizer and lungs, with manifestations of chest tightness, shortness of breath, exacerbation after exercise, or high fever without bringing down, poor appetite, bitterness in mouth, fatigue, diarrhea, loose stools, and yellow and thick tongue fur. As the pathogen can go outward or enter more deeply inside to cause death at the moment, it is the crucial time to treat the disease. In this study, Haoqin Qingdantang was used to clear dampness and heat, reconcile Shaoyang channel and recover the triple energizer, detoxify the dampness fever epidemic toxin, and block the toxin inside, with a good efficacy. This prescription focuses on smoothing the Shaoyang gallbladder channel and the triple energizer, and regards the spleen and stomach as the acquired essence. In the prescription, Erchentang reconciles the spleen and stomach, elevates clear Qi and lower turbid Qi. Bupleuri Radix is added to increase its detoxification function, and Paeoniae Rubra Radix is added to circulate the blood and prevent pathogen from the blood. When the condition improves, Sweet Wormwood Herb and talc are often withdrawn, and Codonopsis is added to nourish the spleen and stomach, to strengthening vital qi to eliminate pathogenic factor. Based on the cases of COVID-19 treated in Wuhan Jinyintan Hospital, this paper summarized some experience of applying Haoqin Qingdantang.

Effect of Kuanxiong Aerosol () on Patients with Angina Pectoris: A Non-inferiority Multi-center Randomized Controlled Trial / 中国结合医学杂志

<p><b>OBJECTIVE</b>To evaluate the effect and safety of Kuanxiong Aerosol (, KA) on patients with angina pectoris.</p><p><b>METHODS</b>Block randomization was performed to randomly allocate 750 patients into KA (376 cases) and control groups (374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA (0.6 mL per spray). The control group received 1 sublingual nitroglycerin tablet (NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment (1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors inflfluencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society (CCS) classes of angina.</p><p><b>RESULTS</b>The 5-min remission rates in the KA and control groups were not signifificantly different (94.41% vs. 90.64%, P>0.05). The angina CCS class signifificantly inflfluenced the rate of remission (95% confidence interval = 0.483-0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSII and III subgroups (P>0.05), while they were signifificantly better for KA in the CCSI and II subgroups (P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was signifificantly lower in the KA group than in the control group for the CCSII and III subgroups (9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01).</p><p><b>CONCLUSIONS</b>KA is not inferior to NT in the remission of angina. Furthermore, in CCSII and III patients, KA is superior to NT, with a lower incidence of adverse reactions. (Registration No. ChiCTRIPR-15007204).</p>

Effect of Kuanxiong aerosol on coronary heart disease angina patients: a multicenter randomized controlled clinical study / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To evaluate the anginal attack-relieving efficacy and safety of Kuanxiong Aerosol (KA) in patients with coronary heart disease (CHD).</p><p><b>METHODS</b>A total of 780 patients confirmatively diagnosed as CHD angina from November 2011 to December 2012 in 13 medical centers in the mainland area were assigned to 2 groups by blocked randomization, the treatment group (376 cases) and the control group (374 cases). When the angina attacked, patients in the treatment group received sublingual spray three times, 0.6 mL each time, while those in the control group sublingually dissolved Nitroglycerin Tablet (NT), 0.5 mg each tablet. The effective rate of angina relief, efficacy of electrocardiogram (ECG), and the incidence of adverse reactions were observed.</p><p><b>RESULTS</b>The 3 min and 5 min remission rates of angina attack were 53.72% (202/376) and 94.41% (355/376) in the treatment group, and 47.86% (179/374) and 90.64% (339/374) in the control group. The 95% confidence interval (CI) of the difference between the 2 groups of 3 min and 5 min remission rates of angina attacks were [(-1.84%, 12.32%) and (-1.33%, 6.85%) respectively, P > 0.05]. The total improvement rates of ST-T changes in the treatment group and the control group after treatment were 74.07% and 73.13% respectively (P > 0.05). The adverse reaction rate was 9.31 (35/376 cases) in the treatment group and 22.46% (84/374 cases) in the control group (P < 0.01).</p><p><b>CONCLUSION</b>KA was not inferior to NT in relieving anginal attacks and improving ischemic ECG changes, and had obviously less adverse reaction.</p>
