RESUMO

The pathological anatomical results of coronavirus disease-2019 (COVID-19) patients showed that excessive inflammatory reaction in the lungs is one of the important causes for such complications as acute lung injury or acute respiratory distress syndrome. Therefore, regulation of immune response may be an effective measure for COVID-19. Alveolar macrophages have a high heterogeneity and plasticity. The dynamic changes of subsets balance and function of M1/M2 alveolar macrophages have a significant effect on pulmonary inflammatory response during the early and late stages of infection. This paper reviews the classification and function of macrophages and explores the mechanism of alveolar macrophage in the pathological process of COVID-19 at different stages and the pharmacodynamic mechanism of traditional Chinese medicine. Besides, it provides ideas for the treatment of COVID-19 with traditional Chinese medicine and other drugs' research and development based on the regulation of macrophage polarization.

RESUMO

Coronavirus disease-2019 (COVID-19) is an acute infectious disease caused by a 2019 novel coronavirus (2019-nCoV) infection. It is highly contagious, and can spread quickly home and abroad. It has caused a global pandemic. After the outbreak, Gansu province actively responded to the national "integrated Chinese and western medicine(ICWM)" epidemic prevention policy by organizing an expert group on the prevention and treatment of traditional Chinese medicine(TCM) and establishing a joint working mechanism of ICWM. In adherence to the principle of ICWM, it highlighted the advantages of TCM in epidemic prevention, and emphasized early, timely and whole course use of TCM. The expert group continued to summarize in practice and form a series of "Gansu prescriptions", so as to explore the prevention and control strategy of "prevention in advance, timely interruption and reversal, early prevention and cure, and cure in early stage". Before illness, the prevention shall be made in advance by taking Fuzheng Biwen prescription based on constitution differentiation, in order to strengthen the body resistance and removing pathogenic Qi, after the onset, the syndromes were first treated, interrupted and reversed, and Xuanfei Huazhuo prescription and Qingfei Tongluo prescription were administered based on syndrome differentiation, so as to exorcise pathogenic Qi and cure COVID-19 at the early stage, at the beginning stage of recovery, Jianpi Yifei prescription was used to strengthen the spleen and lungs, and harmonize the stomach and resolve dampness, so as to prevent recurrence. In the principle of ICWM, "Gansu prescriptions" were selected based on the constitution differentiation and syndrome differentiation, so as to prevent the occurrence of epidemics, block light and common symptoms from developing to heavy and critical symptoms, improve the clinical efficacy, shorten the course of disease, and reduce the incidence of critical illness, thereby reducing mortality.

RESUMO

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.

RESUMO

Objective: To observe the clinical effect of Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method versus ordinary acupuncture on superficial fascia for treating neck type cervical spondylopathy in Kyrgyz. Methods:A total of 64 Kyrgyz patients conforming to the diagnostic criteria of neck type cervical spondylopathy were included. The patients were randomized into a Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and a conventional acupuncture group, with 32 cases in each group. Patients in the Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were treated with Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method to stimulate the superficial fascia, the stimulation sites were primarily located at bilateral sides of the cervical vertebra as well as the trigger points in shoulder-neck region; patients in the conventional acupuncture group were punctured at the same acupoints, with twirling reducing method, and the depth of insertion was determined by the treated region. Patients in both groups received treatment every day for a succession of 5 d as a course, with a 2-day interval between 2 courses, and the whole treatment lasted for 3 courses. After 3 courses of treatment, the McGill pain questionnaire (MPQ) and neck disability index (NDI) were measured to compare the clinical effect between the two groups. Results: After treatment, scores of MPQ and NDI scale dropped when compared with those before treatment, and the differences showed statistical significance (allP<0.05); scores of MPQ and NDI in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group were substantially lower than those in the conventional acupuncture group, and the differences showed statistical significance (allP<0.05). The total effective rate was 96.9% in the Jin Gou Diao Yu (gold-hook-fishing) acupuncture group and the cured rate was 78.1%, which were higher than 81.3% and 40.6% in the conventional acupuncture group, and the differences showed statistical significance (bothP<0.05). Conclusion: Zheng's Jin Gou Diao Yu (gold-hook-fishing) acupuncture method by stimulating superficial fascia to treat cervical spondylopathy in Kyrgyz can produce a better clinical effect than conventional acupuncture treatment, and is effective in improving pain and stiffness in patients, and thus is worth clinical popularization.

RESUMO

<p><b>OBJECTIVE</b>To investigate the ways testosterone influences the murine bone marrow-derived macrophages (BMMs) and how testosterone affects the function of BMMs after bound to their membrane surface.</p><p><b>METHODS</b>BMMs were cultured in vitro, their total RNA and proteins isolated, and the expression of intracellular androgen receptor (AR) detected through RT-PCR and Western blotting. The binding site of testosterone (T) to the membrane surface of BMMs was observed by confocal laser scanning microscopy after T-BSA-FITC incubation. Moreover, the intracellular Ca2+ was tested by Fura-2 method, and the influence of ionic currents on BMMs plasma membrane induced by testosterone was examined by the whole cell patch-clamp.</p><p><b>RESULTS</b>RT-PCR and Western blotting failed to detect intracellular ARs in BMMs, but confocal laser scanning microscopy showed testosterone to be bound to the membrane surface of BMMs by impermeable T-BSA-FITC, inducing a rapid rise in the intracellular free Ca2+ concentration ([Ca2+]i) of Fura-2 loaded BMMs, predominantly due to the influx of extracellular Ca2+ through Ni2+ -blockable Ca2+ channels in the plasma membrane. Similarly, the patch-clamp technique revealed T-induced calcium influx in BMMs.</p><p><b>CONCLUSION</b>It is reasonable to assume that the testosterone receptor exists on the plasma membranes, and testosterone act through unconventional plasma membrane receptors, induce Ca2+ influx and a rapid rise in the intracellular Ca2+ concentration, and influence the function of BMMs.</p>
