ABSTRACT
The outbreak of corona virus disease-2019 (COVID-19) not only endangers the public life and health, but also poses threats to the public mental health. Under the atmosphere of tension and fear, the public often produces adverse emotional reactions to psychological stress, and even has extreme behaviors, which seriously affects physical and mental health. Traditional Chinese medicine （TCM） emotional therapy is based on the TCM consciousness theory in adherence to the holistic view of "integration of mind and body". It adopts safe and effective emotional conditioning methods to regulate mood, eliminate bad emotions, maintain mental health, and enhance the body's immunity to achieve the effect of treating or preventing physical and mental diseases. It has differentiated applications in many medical fields, such as post-traumatic stress disorder, generalized anxiety disorder, cancer and hospice, with good clinical efficacy. By analyzing the theoretical origin, research status, application range of TCM sentiment therapy, as well as the current public psychological state of the COVID-19 epidemic, we innovatively proposed TCM sentiment therapies, such as calm emotion method, diversion of attention method, suggestive induction method, obedient mind method, music delight method, TCM refreshing method and auricular pressing method, and comprehensively applied them in the public psychological adjustment during the outbreak, with the aim to provide rational and effective psychological guidance, help the public to correctly understand various bad emotions during the outbreak, enhance their abilities to cope with it and adjust psychological problems, maintain a good mentality, and pass the epidemic period smoothly. At the same time, in order to make better use of the advantages of TCM sentiment therapy and benefit the public, it is advocated to widely apply TCM sentiment therapy in similar public health events and public psychological care in the daily life, for the purpose of preventing before disease outset and preventing progress of disease, and effectively protecting the physical and mental health of the people.
ABSTRACT
Some patients with corona virus disease-2019 (COVID-19) experienced a severe exacerbation of the disease due to the occurrence of inflammatory storm during the development of the disease. They are complicated with acute respiratory distress, multiple organ dysfunction syndrome and other serious complications, with a poor prognosis and a high mortality. For the inflammation storm, western medicine mostly adopts glucocorticoids, nutritional support, artificial ventilation assistance and other measures at present. The development of artificial liver, blood purification therapy, extracorporeal membrane oxygenation and other technologies have also reduced the mortality of patients to some extent. However, due to the high requirements for equipment, the measures have not yet been widely carried out. From the perspective of traditional Chinese medicine(TCM), the basic pathogenesis of COVID-19 is epidemic toxin invasion, lung and spleen being affected by pathogens, damaging vital Qi, and pathological properties involving dampness, heat, poison, stasis and deficiency. At the stage of inflammation storm, the pathogens are abundant, while the vital Qi is deficient， and the pathogens occlude lung, and disturb the heart and mind, and blood stasis and toxicity are combined with Qi-Yin deficiency. In severe cases, even both Yin and Yang exhaustion occurs. At present, a number of studies have shown that a variety of Chinese herbal medicines have multi-target immunomodulatory effect on viral pneumonia and cytokine storm. TCM participates in whole process of the occurrence and development of inflammation storm, mainly eliminating pathogens in early stage, controlling inflammation and blocking occurrence of inflammation storm， eliminating pathogens and strengthening the body resistance to eliminate the pathological products of the inflammation storm, and promoting the dissipation and absorption of inflammation in the middle stage， and saving lives in late stage by benefiting Qi and relieving depletion, and restoring Yang and rescuing from collapse. On the basis of pathophysiological mechanism of COVID-19 inflammation storm and the theory of TCM syndrome differentiation and treatment, this paper summarized the pharmacological studies on intervention on inflammatory storm with relevant Chinese herbal medicine, Chinese medicine prescriptions and Chinese medicine preparations, and discussed the intervention measures of TCM in different development stages of inflammatory storm, in expectation of providing the guidance for clinical treatment.
ABSTRACT
The outbreak of corona virus disease-2019 (COVID-19) in Wuhan, China, in December 2019, is highly contagious and epidemic, and belongs to the category of "plague" in traditional Chinese medicine, which seriously threatens human life and health. In the face of this sudden public health event, based on the theory of Wenyilun, this paper analyzes the onset characteristics, transmission, and syndrome differentiation-based treatment of COVID-19 in clinical practice. According to the characteristics of this epidemic, the pathogeny of COVID-19 is "epidemic pathogenic factors", and the pathogenesis is that the epidemic suppresses the dampness. Its transmission follows the regularity of "nine transmissions between exterior and interior" recorded in Wenyilun, which can be divided into sequential transmission and reverse transmission. The course of the disease has certain regularity and stages. In the early stage, the pathogen hides in the pleurodiaphragmatic interspace, and the epidemic suppresses the dampness， the treatment shall reach the pleurodiaphragmatic interspace, clear the dampness and turbidness, diffuse the lungs and dredging the lung meridian. In the middle stage, the pathogen can be transmitted to the exterior， the treatment shall be pungent in flavor and cool in property and could relieve the exterior syndrome, so as to remove the pathogen by shivering and sweating. If the dampness toxin enters the interior and be transmitted into the heat, and caused damage to the lung meridian, obstruction of Qi in the lungs, interior excess and heat accumulation, the treatment shall dredge bowel and purge heat, and expel the pathogen out. Any delay in treatment, mistreatment or excessive pathogen can lead to pathogenic invasion into the pericardium, and cause delirium, dysphoria, reversal cold of limbs, barely palpable pulse and other critical manifestations of internal blocking causing external depletion. The treatment shall focus on both attack and supplement, open blocking and relieve depletion. In the recovery period, due to the residual pathogen and the Yin and Qi impairment caused by fever, the treatment shall prevent the recurrence of the residual pathogen, nourish Yin and blood, and restore the vital energy. During the treatment, WU You-ke put forward three principles of "removing the pathogen as the priority, and then avoiding false sweating, and caring for the spleen and stomach". The theory of Wenyilun has a systematic understanding of the pathogeny, pathogenesis, and syndrome differentiation-based treatment of "the epidemic", and provides valuable experience for fight against plagues in later generations, which is also of great significance for the prevention and treatment of COVID-19.
ABSTRACT
Since the outbreak of corona virus disease-2019 (COVID-19), the timely intervention of Chinese medicine has played an important role， it can significantly improve the clinical symptoms of patients, alleviate fever, cough, shorten the course of disease and reduce the conversion rate of mild disease to severe disease， moreover, it has obvious advantages in improving survival rate, prognosis and quality of life in patients. In order to make better use of the therapeutic effect of Chinese medicine and overcome the epidemic situation as soon as possible, various provinces, municipalities and autonomous regions have introduced local Chinese medicine treatment schemes in accordance with the geography, climate and epidemic situation. In this article, we have analyzed the similarities and differences among treatment schemes from the perspective of three factors, and it is believed that the onset season is the same for this disease, and the differences between treatment schemes mainly depend on geographical and climatic factors. The results showed that in seven regions of China, the early symptoms in warm and humid regions such as Central China, South China, East China and Southwest China were characterized by "wet, warm, hot, and toxic", and treatment schemes mainly adopted the recipes with clearing heat and detoxifying, strengthening spleen and removing dampness functions. The early symptoms in cold regions such as Northeast China, North China, and Northwest China were mostly characterized by "cold, wet, wind, and toxic", and the therapeutic recipes emphasized on the effects of expelling wind and cold, removing toxicity and dampness. Among them, the national plan with the Hubei epidemic situation as an important reference has gradually evolved from a single syndrome attribute of each period to both cold and hot syndromes with multiple treatment methods. With the development of the disease, epidemic toxin and toxic heat in the lungs are the main characteristics in the medium term, when the treatment mainly focuses on purging heat and removing toxins. In severe cases and advanced stage, internal block and outward desertion are the main symptoms, when the treatment mainly focuses on block dredging and relieving desertion. In the recovery period, deficiency of lung and spleen Qi, and deficiency of Qi and Yin are the main symptoms, when the treatment is mainly used to invigorate the spleen, tonify the lungs, and nourish Qi and Yin. The physical factors are mostly reflected in the prevention program, so they are rarely mentioned in the treatment program. The Chinese medicine treatment schemes of COVID-19 in different regions show obvious differences. It is of great significance to analyze these differences and sum up the corresponding laws for the differential prevention and treatment of infectious diseases like COVID-19.
ABSTRACT
Objective:To explore the effect of Paiteling on the proliferation，metastasis and invasion of HeLa cells and relevant proteins of phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway. Method:① HeLa cells were divided into blank group and Paiteling concentration gradient groups (3.906，2.604，1.953，1.563，1.302，1.116，0.977 g·L-1). After drug intervention for 24 h，the cell morphological changes were observed under microscope. The cell viability was measured by thiazole blue (MTT) colorimetry，and the half inhibitory concentration (IC50) of Paiteling on HeLa cells was calculated. ② HeLa cells were divided into blank group，cisplatin group (0.01 g·L-1)，Paiteling high-dose group (2.974 g·L-1)，Paiteling medium-dose group (1.487 g·L-1) and Paiteling low-dose group (0.991 g·L-1). Cell proliferation and toxicity test (CCK-8) method was used to detect the effect of Paiteling on the proliferation ability of HeLa cells，scratch test was used to detect cell migration，and invasion test (Transwell) was used to detect changes in cell invasion ability. ③ Inhibitor LY294002 group (0.006 g·L-1) was added. Western blot (WB) was used to detect the expressions of Paiteling on PI3K，Akt，recombinant human B-cell lymphoma factor-xl (Bcl-xl)，and B-cell lymphoma/leukemia associated D protein (Bad). Result:① Compared with the blank group，microscopic observation showed that the number of cells in the treatment group was significantly reduced, and the cell morphology was incomplete. MTT experiments showed that Paiteling has a significantly inhibitory effect on HeLa cell proliferation (P<0.01). The IC50 of Paiteling on HeLa cells was calculated as 2.974 g·L-1. ② The CCK-8 experiment showed that compared with the blank group，all the drug-treated groups had an inhibitory effect on HeLa cell proliferation at 24，36，48 h (P<0.01), compared with the cisplatin group，middle and low-dose Paiteling groups showed a reduced inhibitory effect on HeLa cell proliferation at each time point (P<0.01). The scratch test showed that，compared with the blank group，each drug-added group could inhibit the migration ability of HeLa cells (P<0.01)，and the cell migration rate of the high-dose Paiteling group was lower than that of the cisplatin group (P<0.05). Transwell experiments showed that compared with the blank group，the number of membranes permeated by HeLa cells in each drug-treated group was decreased (P<0.01)，and the number of membranes permeated in the middle and low-dose Paiteling groups was increased compared with the cisplatin group (P<0.01). ③ Western blot showed that compared with the blank group，the expression levels of PI3K，Bcl-xl，and Akt in the high，medium，and low-dose Paiteling groups and the LY294002 group decreased (P<0.05，P<0.01)，while the expression of Bad increased (P<0.01). Compared with the high-dose Paiteling group，the PI3K，Akt，and Bcl-xl protein expressions were increased in the low-dose Paiteling group (P<0.01)，whereas Bad expression was decreased (P<0.01). Conclusion:Paiteling can inhibit HeLa cell proliferation，metastasis and invasion ability in a dose-dependent and time-dependent manner，which may be related to its effect on the expressions of PI3K/Akt signaling pathway-related proteins.
ABSTRACT
Objective:To investigate the renal protective effect of Tangshenping capsule (Tangshenping) on diabetic nephropathy (DN) KKAy mice and its effect on Wnt/β-catenin signaling pathway. Method:Sixty female Sprague-Dawley KKAy mice aged 10 weeks old were induced with KKAy rat feed for 10 weeks. The DN animal model was successfully determined with blood glucose (>16.7 mmol·L-1) and 24 hour urine protein (>0.4 mg). The model mice were randomly divided into a model group, an irbesartan group, and low, medium and high-dose Tangshenping group, with 10 female C57BL/6J mice as a control group. The treatment groups were given the corresponding drugs by gavage. The normal group and the model group were given an equal volume of deionized water by gavage. The intragastric dose was 0.01 mL·g-1 body weight coefficient once a day. The general conditions of the mice were observed, the body mass was weighed every 4 weeks, and 24 h urine protein was quantified. At the 26th week, the blood was collected from eyeballs, and the mice were put to death. The quality of the kidneys, serum blood urea nitrogen (BUN), serum creatinine (SCr), triglyceride (TG), malondialdehyde (MDA), nitric oxide (NO) and superoxide dismutase (SOD) content were measured. In situ hybridization and immunohistochemistry were used to detect the expressions of Wnt4, glycogen synthase kinase 3β(GSK3β) and β-catenin in kidney tissues. Result:Compared with model group, body mass, kidney mass/body mass, and 24 h urine protein were significantly lower in high-dose Tangshenping group (PPPβ and β-catenin were decreased (PConclusion:Tangshenping may inhibit the activation of Wnt/β-catenin signaling pathway, reverse the transdifferentiation of renal tubular epithelial cells in DN KKAy mice, delay the progression of renal interstitial fibrosis, and then exert renal protection.
