Viral pneumonia is an infectious disease caused by virus invading the lung parenchyma and interstitial tissue and causing lung inflammation, with the incidence rising year by year. Traditional Chinese medicine (TCM) can treat viral pneumonia in a multi-component, multi-target, and holistic manner by targeting the core pathogenesis of pneumonia caused by different respiratory viruses, demonstrating minimal side effects and significant advantages. According to the theory of healthy Qi and pathogenic Qi in TCM, the struggle between healthy Qi and pathogenic Qi and the imbalance between immunity and inflammation run through the entire process of viral pneumonia, and the immunity-inflammation status at different stages of the disease reflects different relationships between healthy Qi and pathogenic Qi. Immune dysfunction leads to the deficiency of healthy Qi, causing viral infections. The struggle between healthy Qi and pathogenic Qi causes immunity-inflammation imbalance, leading to the onset of viral pneumonia. Inflammatory damage causes persistent accumulation of phlegm and stasis, leading to the progression of viral pneumonia. The cytokine storm causes immunodepletion, leading to the excess of pathogenic Qi and diminution of healthy Qi and the deterioration of viral pneumonia. After the recovery from viral pneumonia, there is a long-term imbalance between immunity and micro-inflammation, which results in healthy Qi deficiency and pathogenic Qi lingering. Healthy Qi deficiency and pathogenic Qi excess act as common core causes of pneumonia caused by different respiratory viruses. Clinical treatment should emphasize both replenishing healthy Qi and eliminating pathogenic Qi, helping to restore the balance between healthy Qi and pathogenic Qi as well as between immunity and inflammation, thus promoting the recovery of patients from viral pneumonia. According to the TCM theory of healthy Qi and pathogenic Qi, this article summarizes the immunity-inflammation mechanisms at different stages of viral pneumonia, and explores the application of the method of replenishing healthy Qi and eliminating pathogenic Qi in viral pneumonia. The aim is to probe into the scientific connotation of the TCM theory of healthy Qi and pathogenic Qi in viral pneumonia and provide ideas for the clinical application of the method of replenishing healthy Qi and eliminating pathogenic Qi to assist in the treatment of viral pneumonia.

The principle of treating different diseases with the same therapy is the essence of syndrome differentiation and treatment in traditional Chinese medicine (TCM). It means that when the same pathogenic changes or the same symptoms appear in the development of different diseases, the same principles or methods can be used for treatment. Due to the complexity and high variability of viral pathogenicity, the precise and effective treatment of different types of viral pneumonia (VP) has always been a research focus and difficulty in modern medicine. VP belongs to the category of external-contraction febrile disease, warm disease, and epidemic in TCM. Haoqin Qingdantang (HQQDD) is a representative formula for clearing heat and dispelling dampness in warm diseases, and its intervention in VP caused by various viral infections has significant effects. This study, guided by the theory of treating different diseases with the same therapy, links the related studies on using HQQDD to treat different types of VP and finds that influenza virus pneumonia (IVP), severe acute respiratory syndrome (SARS), and COVID-19 all have a common pathogenic mechanism of dampness-heat at different stages of respective diseases. When these diseases are dominated by damp-heat factors, the use of HQQDD yields remarkable therapeutic effects. Modern pharmacological studies have confirmed that HQQDD can inhibit virus replication, reduce fever reactions, inhibit the expression of inflammatory mediators, and regulate immune balance. Moreover, the sovereign medicine in this formula has excellent antiviral activity, and the formula reflects rich scientific connotations of treating VP. According to the theory of treating different diseases with the same therapy and based on the effective treatment practice and modern pharmacological research of HQQDD for different types of VP, this paper mines the underlying TCM theory of treatment with the same therapy, explores the syndrome differentiation and treatment strategy and effect mechanism of this formula for different types of VP, and analyzes the treatment mechanism and characteristics, with the aim of providing evidence and reference for the clinical application and modern research of HQQDD.

Objective:To investigate the discomfort of chest wall approach area in patients undergoing endoscopic thyroidectomy by a gasless unilateral axillary approach (GUA), and to analyze its influencing factors. To provide a basis for the development of targeted improvement measures.Methods:A total of 153 patients with GUA from May. 2023 to Aug. 2023 in the Department of Thyroid Surgery, the First Affiliated Hospital of Zhengzhou University were selected as the study subjects. The general information questionnaire was collected one day before operation, the pain scales were assessed one day and three days after operation, and the pain and numbness scales were assessed one month after operation. The t test or χ2 test was used for comparison of baseline data between groups according to different types of variables. The patients were divided into two groups: less than moderate pain group (two postoperative average VAS scores<4) and more than moderate pain group (two postoperative average VAS scores ≥4). Mild numbness group (postoperative VAS score<4) ; Moderate and severe numbness group (postoperative VAS score ≥4). Multivariate binary Logistic regression was performed with pain discomfort and numbness discomfort as dependent variables to find possible influencing factors. Results:A total of 153 valid questionnaires were collected. There were 125 patients in the moderate pain group; There were 28 patients in the moderate and above pain group. There were 94 patients in the mild numbness group. There were 59 patients in the moderate to severe numbness group. Multivariate binary Logistic regression results showed that, exercise habits ( OR=0.07 95% CI=0.006, 0.409), operation duration ( OR=1.026 95% CI=1.001, 1.054), total drainage volume ( OR=1.122 95% CI=1.07, P<0.05), 1.198), and drainage tube indwelling time ( OR=0.012 95% CI=0.0, 0.187) had an impact on the discomfort of the chest wall approach area, and the difference was statistically significant ( P<0.05). Gender, BMI, marital status, education, occupation, handed-side surgery, handed-side axillary surgery, smokess and alcohol history, intraoperative blood loss, and length of hospital stay had no effect on the discomfort of chest wall approach area, and the difference was not statistically significant ( P>0.05) . Conclusion:Exercise habits, operation duration, total drainage volume, and drainage duration are independent predictors of discomfort in GUA patients.

Viral pneumonia (VP) is an inflammatory disease caused by one or more viruses that infect the upper respiratory tract and spread downward. Causing varying degrees of pulmonary parenchymal damage, VP poses a serious threat to the society and public health. The treatment of VP now faces the dilemma of drug shortage, since Western medicine can only alleviate symptoms and lacks specific treatment methods. In traditional Chinese medicine (TCM), VP is assigned as an epidemic disease, with the etiology attributed to epidemic toxin and six excesses and the pathological factors of dampness, heat, toxin, deficiency, and stasis. The basic pathogenesis of VP is Yin-Yang imbalance, dysfunction of Zang-Fu organs, and healthy Qi deficiency. Accordingly, the treatment should follow the principle of replenishing healthy Qi and expelling pathogen. The treatment method of VP is mainly developed based on syndrome differentiation of six meridians, defense-Qi-nutrient-blood, and triple energizer. Xuanfei Baidu prescription (XFBD) is an effective prescription developed by Academician ZHANG Boli and Professor LIU Qingquan by literature research and selection of multi-component Chinese medicine. It is the product of modern research combined with TCM. XFBD is modified from Maxing Shigantang, Maxing Yigantang, Tingli Dazao Xiefeitang, Qianjin Weijingtang, and Buhuanjin Zhengqisan. It is mainly used to treat epidemic diseases with the syndrome of dampness toxin stagnating in the lung, with the effects of ventilating lung and resolving dampness, clearing heat and expelling pathogen, purging lung, and removing toxin, demonstrating the potential for the prevention and treatment of VP. This paper reviews the research progress of XFBD in combating VP in terms of the prescription composition, compatibility ideas, indications, and clinical new applications, as well as the pharmacological mechanisms of inhibiting virus, reducing inflammation, regulating immune system, ameliorating pulmonary fibrosis, and modulating intestinal flora. In addition, we put forward our thoughts and suggestions on the problems in the research, with a view to informing the clinical use of drugs and the basic research on the treatment of VP including COVID-19.

Objective To explore the effects of the same dose of fractionated radiation and single radiation on radiation-induced heart damage in mice.Methods Twenty-one wild-type C57BL/6J mice were randomly divided into the normal group,fractionated radiation group and single radiation group.18 Gy X-ray,via fractionated(3 Gy/time,6 times)radiation or single radiation,was used to establish a radiation-induced heart damage model.The concentrations of myocardial enzyme damage markers(creatinekinase(CK),creatinekinase-MB(CK-MB),lactate dehydrogenase(LDH)and LDH1)and peripheral serum ions(K+,Ca2+,Fe2+and Cl-)were detected by an automatic biochemical analyzer at day 7 and 28 after radiation.Ultrasound was used to detect and analyze the cardiac function of mice at day 28 after radiation,including the left ventricular ejection fraction(EF),left ventricular fractional shortening(FS),left ventricular end-diastolic volume(LVEDV),left ventricular mass(LV mass)and left ventricular end-systolic volume(LVESV).The opening of the mitochondrial permeability transition pore(mPTP)and changes of mitochondrial membrane potential of myocardial cells were observed using a laser confocal microscope.The ultrastructure of myocardia was observed under a transmission electron microscope(TEM)and cardiac fibrosis was checked by Masson staining.The atherosclerosis of the aorta was examined by gross oil red staining.Real-time quantitative PCR(RT-qPCR)and Western blotting were performed to detect the expressions ofapoptosis-related genes and proteins,B cell lymphoma-2-associated X protein(BAX)and casepase-3.Results Seven days after 18Gy X-ray irradiation,the expression levels of CK,CK-MB,LDH and LDH1 in the single radiation group increased significantly or trended up,while only CK and LDH1 in the fractionated irradiation group continued to increase.Twenty-eight days after radiation,the expression levels of 4 enzymes in myocardial zymogram were increased by both radiation methods.Seven and twenty-eight days after radiation,the concentrations of serum ions K+,Fe2+,Ca2+and Cl-were significantly decreased by both radiation methods that could lead to the decrease of EF and FS,and the increase of LV mass,LVEDV and LVESV.Single radiation made more difference to EF and FS,and the difference between the two groups was statistically significant.Both methods could decrease the mPTP and mitochondrial membrane potential,especially single radiation,and there was significant difference between the two groups.The results of TEM showed that the mitochondrial cristae of myocardial cells decreased and vacuolated,and the myocardial fiber bundles became thicker after X-ray radiation.Masson staining showed that collagen fibers were deposited in the heart tissue ofmice after X-ray irradiation,particularly in the single radiation group.Gross oil red staining ofthe aorta showed that both methods could damage the aorta of mice,and the area of atherosclerotic plaques in the single radiation group was larger,which was statistically different from that of the fractionated radiation group.The results of RT-qPCR and Western blotting showed that X-ray radiation could increase the expression levels of apoptosis-related BAX and caspase-3 in cardiac tissue,especially in the single radiation group.The mRNAexpressions of BAX and caspase-3 increased more significantly in the single radiation group.Conclusion Both fractionated radiation and single radiation at the same dose can cause heart damage,so they can be used to establish a radiation-induced heart damage model of mice.Single radiation can cause more significant damage to the heart.Different modeling methods can be selected as required.
