RÉSUMÉ
To summarize Professor TU Jinwen's clinical experience in the treatment of severe influenza based on the “heat toxin theory”. He believed that “heat toxin” is the main disease mechanism of severe influenza， emphasized the pathogenesis process that toxin enters with the pathogenic qi， heat generates by the toxin， and changes initiate from the toxin， and proposed simultaneous treatment of warmth and toxin and combination of multiple methods as the treatment principles. Syndrome differentiation in clinic should combine with wei-qi-ying-blood. The disease in the early stage located in wei （defensive） and qi level， treated by clearing heat and resolving toxins， releasing the exterior and expelling pathogen， harmonizing the exterior and interior， dredging the bowels with diarrhea， and combining other methods to get rid of the heat and toxin， and modified Self-Prescribed Tuire No. 1 Formula （自拟退热1号方） is recommended； the disease in progression stage located in ying-blood， treated by relieving heat and resolving toxins， and clearing the ying level and cool the blood， with prescriptions as modified Self-Prescribed Tuire No. 1 Formula plus Qingying Decoction （清营汤）， or Xijiao Dihuang Decoction （犀角地黄汤）； the disease in the late stage with of yin fluid consumption， and heat toxin in the blood level， treated by eliminating heat and resolving toxins， and enriching yin and cooling the blood， with prescriptions as modified Shashen Maidong Decoction （沙参麦冬汤） and Zhuye Shigao Decoction （竹叶石膏汤）. At the same time， it is emphasised that heat-clearing and fire-draining method and harmonising methods are important， and that dispelling pathogen should not injure healthy qi， and that the selection of prescriptions and medicines need consider syndrome differentiation and treatment.
RÉSUMÉ
Lung cancer has the highest incidence and mortality rate among all cancers in China， with its complex and variable nature， long treatment duration， and often poor prognosis. Currently， the treatment of lung cancer mainly employs classical therapies such as surgery， radiotherapy， and chemotherapy， but some patients may experience a series of adverse reactions， which affect their quality of life， survival period， and treatment outcomes. As reported， oxidative stress is one of the important pathogenic factors of lung cancer， affecting its occurrence and development. Oxidative stress is a state of imbalance between oxidative products and antioxidant defense mechanisms in the body. The intervention of oxidative stress in the occurrence and development of lung cancer is related to multiple signaling pathways， including the Kelch-like ECH-associated protein 1 （Keap1）-nuclear factor erythroid 2-related factor 2 （Nrf2） signaling pathway， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway， mitogen-activated protein kinase （MAPK） signaling pathway， and nuclear factor-κB （NF-κB） signaling pathway. Currently， researchers in China and abroad have conducted extensive studies on the occurrence and development of lung cancer and the pathophysiological mechanisms of drug intervention. The results have shown that oxidative stress plays an important role in the occurrence and development of lung cancer. Chinese medicine monomers and compounds can regulate oxidative stress levels and intervene in related signaling pathways， thereby inhibiting or delaying the occurrence and development of lung cancer. Based on this， this article mainly summarized the relevant signaling pathways regulating oxidative stress intervention in lung cancer in recent years， and also reviewed the latest research on Chinese medicine monomers and compounds in regulating oxidative stress to treat lung cancer， aiming to provide new ideas for research on drug treatment of lung cancer and clinical drug development， as well as to provide references and guidance for further in-depth mechanistic studies in the future.
RÉSUMÉ
According to the latest global cancer statistics， the incidence and mortality of lung cancer rank first in China. Classical therapies remain the most common cancer treatment options， such as surgical resection， radiotherapy， and chemotherapy， but not all cancer patients respond to classical therapies， which require new lung cancer treatment strategies. After decades of research and development， cancer immunotherapy has achieved certain curative effect， which provides new possibilities for cancer treatment. Cyclic guanosine monophosphate-adenosine monophosphate synthase （cGAS） is a cytosolic DNA sensor. It can induce protective immune defense responses against various DNA-containing pathogens and provide anti-tumor immunity by activating the interferon （IFN） gene stimulator （STING） protein. At present， relevant researchers in China and abroad have done a lot of research on the occurrence and development of lung cancer and the pathophysiological mechanism of drug intervention in the treatment of lung cancer. The results show that cGAS/STING signaling pathway plays an important role in the development of the disease， and traditional Chinese medicine monomers or compounds can intervene in lung cancer cells by regulating the cGAS/STING signaling pathway， induce their autophagy and death， regulate their cycle operation， promote senescence， inhibit their proliferation and tumor angiogenesis， promote their invasion and metastasis， and promote the immune activation of anti-lung cancer cells， so as to inhibit or delay the occurrence and development of lung cancer. In recent years， the related research results have been updated rapidly， and the previous literature has not included the latest research results in time， which causes a lot of inconvenience for many scholars to search the literature. Based on this， this paper mainly summarized the mechanism of cGAS/STING signaling pathway intervention in lung cancer in China and abroad in recent years， as well as the research progress of related traditional Chinese medicine intervention， so as to provide new ideas for the development of lung cancer in molecular biology， drug treatment research， and clinical new drug research and provide a reference for further mechanism research.

Objective:To explore the therapeutic effect of adipose-derived stem cells (ADSC) on long-wave UV damage in mouse skin in order to provide ideas for the treatment of skin photodamage.Methods:The inguinal and perirenal adipose tissues of C57BL/6 mice were extracted and processed to obtain mouse ADSCs, and the surface markers, adipogenic and osteogenic differentiation capabilities were identified. The mouse photoaging model was irradiated with the SS-03AB UV illuminator, the total UVB dose was 9.45 J/cm 2, and the total UVA dose was 94.5 J/cm 2. Experimental mice (72 in total) were divided into normal group, model group, DMEM (medium) group and ADSC group, each with 18 mice. In the normal group and model group, the materials were taken two weeks after the end of irradiation. After irradiation, the ADSC group was given a subcutaneous injection of 200 μl ADSC suspension, and the DMEM group was given 200 μl of serum-free medium for treatment, and the materials were taken for pathological staining after 2 weeks. The experimental data was processed by analysis of variance. This study was carried out from August 2018 to July 2019 in the First Affiliated Hospital of Zhengzhou University. Results:The extracted cells were identified as adipose-derived stem cells. HE staining showed that the inflammatory cell infiltration in the ADSC group was significantly reduced compared with the DMEM group ( t=20.649, P<0.001) and the normal group ( t=16.147, P<0.001), and the thickness of the dermis layer was significantly increased. Masson staining showed collagen fibers were arranged neatly and the density increased significantly after ADSC treatment. Conclusions:Subcutaneous injection of ADSC can reduce inflammation, promote collagen tissue proliferation, increase the thickness of the dermis, effectively resist inflammatory damage and collagen breakdown caused by UVB.

Objective:To evaluate the efficacy of postoperative radiotherapy (PRT) for dermatofibrosarcoma protuberans (DFSP).Methods:A systematic review and meta-analysis of articles published before February 23, 2019 were conducted. A total of 655 studies were retrieved consisting of 195 DFSP patients. Among them, 50 cases were assigned into the PRT group and 145 cases in the surgery alone (SA) group. The recurrence rate was statistically compared between two group.Results:Meta-analysis showed that the recurrence rate in the PRT group was significantly lower than that in the SA group (8% vs. 24.1%, OR=0.28, P=0.010). The recurrence rate of patients with positive margins in the PRT group was significantly lower compared with that in the SA group (8% vs. 61.5%, P=0.002). The recurrence rate of patients with negative margins in the PRT group had a decreasing trend than that in the SA group (6% vs. 21.6%, P=0.205). Conclusions:The recurrence rate of surgery combined with PRT is lower than that of SA. The recurrence rate of patients with positive margins is higher than that of those with negative margins. For patients with positive margins, PRT can decrease the recurrence rate. The recurrence rate trends to decline in patients with negative margins after receiving PRT.
