Objective:To investigate the effect of microwave on human adenovirus type 2 (HAdV-2) capsid protein in simulated infectious wastes.Methods:Droplets of HAdV-2 virus suspension were added to medical disposable gloves to simulate infectious waste, irradiated under different microwave conditions, the temperature change was recorded, and the irradiated viral supernatant was treated with Dnase I and detected by PCR and qPCR to determine the effect of microwave on the integrity of the viral capsid. ELISA was used to detect the effect of microwave irradiation on the structure of viral hexon protein. The virus was treated alone at the highest temperature during microwave irradiation to investigate whether there were non-thermal effects during microwave disinfection.Results:The maximum temperature during microwave irradiation was 76 ℃, and the PCR and qPCR result showed that Dnase I could significantly damage the viral nucleic acid after microwave irradiation, while the virus control group and heat treatment group were not significantly affected, indicating that microwave irradiation could destroy the integrity of the viral capsid. The result of ELISA showed that microwave irradiation could significantly weaken the binding ability of Hexon protein and antibody, and the result of heat treatment group were similar.Conclusions:Microwave irradiation can destroy the integrity of the HAdV-2 capsid and the structure of Hexon protein, in which the damage to the integrity of the capsid is mainly due to non-thermal effects, and the structural changes of hexon protein are mainly due to thermal effects.

Malignant tumors have surpassed stroke and coronary heart disease to become the main cause of death before the age of 70 in the world. The incidence of malignant tumors is increasing year by year, which seriously affects the living standards and social and economic development of Chinese people. Surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy are the main means of Western medicine to intervene in tumors, which are of great significance for prolonging the survival time of patients. However, there are many disadvantages such as adverse reactions and drug resistance. Traditional Chinese medicine has become a research hotspot in recent years because of its definite curative effect and wide application in tumor treatment. Xiao Chaihutang is derived from the Treatise on Febrile and Miscellaneous Diseases. It is composed of Bupleuri Radix, Scutellariae Radix, Ginseng Radix, Pinelliae Rhizoma, Glycyrrhizae Preparata Radix, Ginger, and Jujube. It has the effects of reconciling Shaoyang, reconciling cold and heat Yin and Yang, soothing the liver, and relieving depression. This prescription and the prescriptions based on it are widely used in various stages of tumors. This study summarized the Chinese and foreign research of Xiao Chaihutang in the field of tumors in the past 10 years and explored the role and mechanism of Xiao Chaihutang in blocking precancerous lesions, controlling the development of malignant tumors, reducing the occurrence of adverse reactions after intervention, and alleviating common complications, with a view to expanding the clinical medication ideas.

Acute myocardial infarction(AMI)is a common cardiovascular emergency in clinic.Early reperfusion is a typical and effective method for the treatment of AMI.However,the recovery of blood supply after reperfusion therapy will accelerate the damage of ischemic myocardium and cause myocardial ischemia-reperfusion injury(MI/RI).In recent years,studies have found that TCM has the unique advantages of multi-component,multi-channel and multi-target in the intervention of MI/RI.Janus tyrosine kinase/signal transducer and activator of transcription(JAK/STAT)signaling pathway is closely related to MI/RI,which can reduce MI/RI process by regulating inflammation,oxidative stress,cell proliferation,differentiation and apoptosis.This article reviewed the mechanism of JAK/STAT signaling pathway in MI/RI and the research of TCM targeting this pathway,in order to provide references for the prevention and treatment of MI/RI and further drug development.

Objective:To study the inactivation effects of microwave on human adenovirus 2 (HAdV-2) in simulated infectied wastes, and to explore its molecular mechanism.Methods:25 μl of HAdV-2 virus suspension was dripped with medical disposable gloves, masks and cotton swabs to simulate infectied wastes, and irradiated under different microwave conditions: gloves and masks were irradiated for 30 s, 60 s, and 90 s at 300 W, 500 W, and 700 W, respectively. Cotton swabs irradiate 60 s, 90 s, 120 s at 500 W and 700 W respectively. Temperature changes were recorded, and the inactivation logarithmic values were calculated by the 50% endpoint method to evaluate the microwave inactivation effects, and the proliferation ability of the virus was detected by qPCR. The damage of Penton, Fiber, Hexon and E2 B genes was detected by PCR. The virus was treated with the highest temperature of 76 ℃ during microwave irradiation to study whether there was non-thermal effect during microwave disinfection. Results:After microwave irradiation of infectied waste, the temperature of masks and gloves carriers rises rapidly, with the highest temperature of 76 ℃. The temperature of the cotton swab carriers rose slowly, and the highest temperature is 65 ℃. The inactivation effect of microwave on HAdV-2 was positively correlated with microwave power and irradiation time. In the mask and glove group, microwave power of 700 W irradiated for 60 seconds, and the inactivation logarithm value could reach 3.0, In the cotton swab group, microwave power of 700 W irradiated for 120 seconds, and the inactivation logarithm value was still less than 3.0. This indicated that there were differences in the conditions for microwave inactivation of the virus in different carriers. The qPCR result showed that microwave irradiation could weak the proliferation ability of the virus. Microwave irradiation had no effect on the virus's Penton and Fiber genes, but caused some damage to the Hexon and E2 B genes. The inactivation effect of individual heat treatment on HAdV-2 was weaker than that of microwave irradiation, and there was no damage to the Hexon, Penton, Fiber, and E2 B genes. This indicated the presence of non thermal effects during the microwave inactivation process. Conclusions:Microwave irradiation can inactivate HAdV-2 in simulated infectied wastes through thermal and non-thermal effects, and its damage to viral DNA is one of the mechanisms of virus inactivation.
