Data-mining-based of ancient traditional Chinese medicine records from 475 BC to 1949 to potentially treat COVID-19.

Traditional Chinese Medicine (TCM) plays a role in preventing and treating COVID-19 in China. Based on the manifestations and symptoms of COVID-19, our study used the data mining method to summarize related therapeutic experience left by predecessors who used TCM to treat epidemics in their eras. Initially, we collected abundant medical records with similar manifestations of COVID-19 in Chinese ancient times. The key words including wen (), yi (), li (), and zhang () were searched in ZhongyiZhiku (https://www.zk120.com/) from Warring States Period (475 BC-221 BC) to the Republic of China era (1912-1949) to locate ancient medical records according to inclusion criteria and exclusion criteria. Moreover, COVID-19-related manifestations and corresponding medications in those records were categorized. Eventually, Traditional Chinese Medicine Inheritance Support System version 2.5 was used to build a medical record database of TCM treating COVID-19. Our study collected 263 epidemic medical records comprising COVID-19 related manifestations and found that Chinese Materia Medica (CMM) combinations excavated from ancient medical records included Ren Shen Bai Du San, Wu Ling San, Xiao Chai Hu Tang, Da Cheng Qi Tang, Da Chai Hu Tang, Ling Gui Zhu Gan Tang, and Qing Wen Bai Du Yin. The recurrent CMMs with a high frequency for treating COVID-19 manifestations were Scutellariae Radix (Huang Qin), Paeoniae Alba Radix (Bai Shao), Poria (Fu Ling), and Bupleuri Radix (Chai Hu). Our study suggests that TCM might offer new therapeutic strategies for COVID-19.

Guidelines on the treatment with integrated traditional Chinese medicine and western medicine for severe coronavirus disease 2019.

Severe Coronavirus Disease 2019 (COVID-19) is characterized by numerous complications, complex disease, and high mortality, making its treatment a top priority in the treatment of COVID-19. Integrated traditional Chinese medicine (TCM) and western medicine played an important role in the prevention, treatment, and rehabilitation of COVID-19 during the epidemic. However, currently there are no evidence-based guidelines for the integrated treatment of severe COVID-19 with TCM and western medicine. Therefore, it is important to develop an evidence-based guideline on the treatment of severe COVID-19 with integrated TCM and western medicine, in order to provide clinical guidance and decision basis for healthcare professionals, public health personnel, and scientific researchers involved in the diagnosis, treatment, and care of COVID-19 patients. We developed and completed the guideline by referring to the standardization process of the "WHO handbook for guideline development", the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, and the Reporting Items for Practice Guidelines in Healthcare (RIGHT).

Photodynamic therapy as an alternative treatment in patients with invasive cutaneous SCC where surgery is not feasible: Single center experience.

The aim of this study was to demonstrate the efficacy of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) as an alternative treatment in cutaneous squamous cell carcinoma (cSCC) patients who are not fit for surgery. Thirty-three invasive cSCC patients who, for some reasons, cannot undergo surgery were enrolled in this study. All patients received plum blossom needle (PBN) pretreated ALA-PDT combined with topical application of 5% imiquimod cream. Two patients dropped the study because of severe pain and two patients discontinue treatment due to lack of response. Of 29 patients, who completed the treatment, 5 patients had complete response after 2-9 sessions of PDT and these patients had no recurrence till 18 months after treatment. Twenty-four patients achieved partial response and are satisfied with treatment outcome in terms of decreased symptoms and improved quality of life. PBN pretreated PDT in combination with topical imiquimod may be a viable treatment option for non resectable cSCC lesions.

Quantitative Proteomics Reveals the Protective Effects of Huangqi Decoction Against Acute Cholestatic Liver Injury by Inhibiting the NF-κB/IL-6/STAT3 Signaling Pathway.

Intrahepatic cholestasis (IC) is a common syndrome that affects the liver, with treatment options being limited. Huangqi decoction (HQD), a classic herbal medicine, has shown protective effects against IC. In this study, isobaric tags for relative and absolute quantification-based quantitative proteomics was performed to investigate the potential mechanism of action of HQD on α-naphthylisothiocyanate (ANIT)-induced IC, resulting in 2796 quantified proteins across all samples, including 270 differentially expressed proteins under HQD treatment. Fuzzy c-means clustering analysis of these 270 proteins assigned the proinflammatory proteins, such as LCN2, SAA1, FGG, FGA, and FGB, to Cluster 1 (upregulated by ANIT, and downregulated by HQD). Functional bioinformatics and protein-protein interaction network analyses indicated that these proinflammatory proteins were involved in the STAT3 signaling pathway. Further real-time PCR and Western blot experiments confirmed that the expression of these proteins was consistent with the proteomic results. Moreover, HQD treatment decreased the phosphorylation of STAT3, induced by ANIT. Western blot experiments revealed that HQD treatment decreased phosphorylation of NF-κB and downregulated the expression of the inflammatory gene IL-6 and therefore inhibited the IL-6/STAT3 signaling pathway. In summary, the present study suggested that HQD may ameliorate acute cholestatic liver injury via inhibition of the NF-κB/IL-6/STAT3 signaling pathway.
