RESUMO
Liver transplant patients require lifelong immunotherapy， and if they are infected by SARS-Cov-2， their immune function will face double whammy. This report described the integrated approach of traditional Chinese and western medicine in the treatment of a liver transplant patient with severe COVID-19. The treatment was involved with western medicine such as antiviral， immunosuppressive， focusing on maintaining immune balance. Traditional Chinese medicine was given based on the differentiation of syndromes， targeting at the core pathogenesis and using methods such as promoting qi circulation， clearing heat and resolving dampness， draining lung and relieving panting. Following the treatment， the patient exhibited notable improvement in clinical symptoms and liver function， leading to the effective cessation of disease progression and a shortened recovery period.
RESUMO
We reported a case of a patient dignosed as tuberculosis and severe malnutrition with coronavirus disease 2019 （critical type） treated with a combination of Chinese medicine and Western medicine. Through the retrospective analysis of the diagnosis and treatment process of this patient， on the basis of Chinese medicine's understanding of the etiology and pathogenesis of “old state” and “deficient state”， the critical coronavirus pneumonia combined with pulmonary tuberculosis and severe malnutrition was mostly due to the physical condition and the invasion of epidemic toxin， resulting in dysfunctions of the internal organs such as the lungs， spleens， kidneys and other organs. Based on the understanding of the cause and mechanism of the coronavirus disease， the treatment combined Chinese and Western medical therapies was given. The western medicine was used with the main treatments of oxygen therapy， anti-viral， intestinal nutritional support， and anti-coagulation， while the Chinese medicine was used by tonifying qi， blood， yin， and yang， warming yang and dissipating cold， and clearing heat and dampness， then tonifying qi， nourishing yin and eliminating heat， in which tonifying middle and replenishing qi ran through the whole process. The integrated treatment eventually improved the patient's symptoms and accelerated the negative conversion of nucleic acid of the coronavirus.
RESUMO
Objective The anti-tumor effect by sequential treatment with Newcastle disease virus (NDV) strain 7793 and 5-FU in liver-metastases mice model was evaluated and immune-active response stimulated by sequential therapy was investigated. Methods Liver metastasis mice model was established by intra-peritoneal injection. The model mice were randomly divided into 3 groups, being given PBS (0.1 mL/d,10 d), NDV7793 [512 HU/(kg·d),5 d] and NDV7793[512 HU/(kg·d),5 d] + fluorouracil [5-FU,10 mg/(kg·d),5 d]. The effect on survival time,body weight,liver weight change and the formation of liver metastasis in tumor-bearing mice model were detected after different treatments in evaluating the regression of mice liver metastasis by sequential therapy. The detection of thymus index and IFN-γ concentrations in liver tissue of tumor-bearing mice model may indicate the stimulation of immune-active response by sequential therapy. Results The mean survival time of tumor-bearing mice treated with NDV7793 and 5-Fu sequentially was 32 d , which was significantly higher than those of tumor-bearing mice treated with NDV7793(30 d) or PBS injections (17 d), respectively (P 0.05), and the liver weight was lighter than PBS (P < 0.05); Compared with NDV treatment, the decreased thymus index and increased amount of the effector IFN γ were observed in tumor-bearing mice treated with NDV 7793 and 5-FU sequentially (P <0.05). Conclusions The sequential therapy with Newcastle disease virus 7793 strain and 5-FU was observed to co-exert a significant suppressive effect in liver metastases of colon cancer cells in tumor-bearing mice model. Compared with NDV treatment , the survival time of mice model and the induction of antitumor effector molecules were significantly improved after sequential therapy.
