ABSTRACT
Acute lung injury (ALI) is a common clinical critical respiratory disease. At present, the mechanism of the disease has not been fully elucidated, there is a lack of specific drugs in clinical practice and the mortality rate is high, which is a difficult problem in the medical field. In recent years, traditional Chinese medicine has exerted its unique advantages and efficacy in the prevention and treatment of ALI, which has aroused the attention of domestic and foreign scholars. Based on the theory of "Wei Qi Ying Xue", this paper discusses the current research status of prevention and treatment of ALI by traditional Chinese medicine, and analyzes its pathogenesis, clinical manifestations and corresponding analysis with TCM syndrome. According to the angle of "Wei Qi Ying Xue", the progress of syndrome differentiation and treatment is highly consistent with immune response, inflammatory response, oxidative stress and apoptosis, in order to find new ideas and medication for the prevention and treatment of ALI with integrated traditional Chinese and Western medicine.
ABSTRACT
Objective:To evaluate the clinical efficacy of Xuanfei Huazhuo prescription in the treatment of coronavirus disease-2019 (COVID-19). Method:A total of 40 patients with COVID-19 were selected and treated with Xuanfei Huazhuo prescription. The changes of body temperature, clinical symptoms, computed tomography (CT), blood routine and biochemical indexes were observed before and after treatment. Result:The 40 patients included 15 males and 25 females, with a male to female ratio of 1∶1.7. They were aged between 20-94 years old, with the average age of （43.9±16.3） years old. The course of disease was 8-23 days, with the average of （14±4.4） days. Compared with before administration, the patients' clinical symptoms, such as cough, fever, sputum, diarrhea, loss of appetite and fatigue, were all improved (P<0.05). Before treatment the traditional Chinese medicine (TCM) syndromes of patients were mainly cold dampness lung (57.5%) and cold dampness Lung (42.5%), and the tongue coating was mainly white greasy coating (52.9%). After adjuvant treatment with Xuanfei Huazhuo prescription, the fever removal time was (2.48±2.56) days; white blood cell (WBC), lymphocyte percentage (LYM%), neutrophil percentage (NEUT%), absolute value of lymphocytes (LYM #) indexes of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), total bilirubin (TBIL), ratio of glutamic oxaloacetic transaminase to glutamic pyruvic transaminase (AST/ALT) and lactate dehydrogenase (LDH) were basically restored to the normal range (P<0.05) compared with before administration. After adjuvant treatment with Xuanfei Huazhuo prescription, the results of three pharyngeal test virus nucleic acid tests were negative, and the lung CT showed that infected lesions were absorbed and all met the discharge criteria. All 40 patients met the discharge criteria and were all cured and discharged, with a cure rate of 100%. There has been no case of recurrence with a positive result of nucleic acid detection so far. The score of symptom and clinical index of patients after administration was （1.62±1.90）, which was significantly lower than that before administration (7.65±4.08, P<0.05). Conclusion:In the adjuvant treatment of COVID-19, Xuanfei Huazhuo prescription can reduce body temperature, promote the absorption of pulmonary inflammation, and improve clinical symptoms, such as fever and cough.
ABSTRACT
To determine the process parameters of optimal water-extraction and ethanol precipitation method for Xuanbi'antong (XBF) extract, which is a clinically experience formula for coronary disease. Orthogonal test L9(34) was conducted for the study of XBF water-extraction and ethanol precipitation process. Extractum, salvianolic acid B, rhizoma coptidis alkaloid, paeoniflorin, puerarin, ginsenoside Rb₁, ginsenosides and echinacoside were selected as marker components and multi-index comprehensive weighted score was used to select and verify optimal water-extraction and ethanol precipitation process. The optimal extraction process was as follows： XBF was added with 10 times distilled water, decocted for half an hour for 3 times. The best ethanol-precipitation process was established where the ethanol was added up to 70% and precipitated for 24 hours in 1.12 extract density (20 ℃). The optimized water-extraction and ethanol precipitation method is stable and reliable, and can provide reference for further development and utilization of the formula.
