The paper introduces the experience of Professor LI Rui in treatment of diseases with bloodletting therapy. Regarding acupoint selection, the main acupoints are selected from the meridians containing excessive blood based on the identification of pathogenesis, and the back-shu points of the foot-taiyang bladder meridian are predominant. The acupoints (e.g. Geshu [BL17], Xuehai [SP10] and Weizhong [BL40]) acting on blood regulations are frequently selected, and the acupoints from the governor vessel (e.g. Dazhui [GV14], Zhiyang [GV9] and Yaoyangguan [GV3]) are specially used for regulating yang qi. Besides, the five-shu points and local points are combined in the prescriptions. This paper expounds the connotation of bloodletting therapy, explores the basis of acupoint selection and clinical application characteristics, and analyzes the clinical cases, so as to provide the approaches to acupoint selection for the clinical application of bloodletting therapy.

Sepsis is a syndrome of systemic inflammatory response in which the body′s response to infection is dysregulated, and is characterized by persistent infection, excessive inflammation and immunosuppression, etc. It often leads to organ dysfunction and can be life threatening, and also a common complication after trauma. The pathogenesis of post-traumatic sepsis is still unclear at present due to the complexity of its etiology, progression and prognosis. Multi-omics technology is a method to combine two or more single omics for comprehensive analysis, which can reveal the interaction network among the disease-associated molecules from multiple perspectives and aspects and is of great significance for the analysis of the pathogenesis of post-traumatic sepsis. To this end, the authors reviewed the research progress on the role of multi-omics technology in elucidating the pathogenesis of post-traumatic sepsis from the perspectives of genomics, transcriptomics, proteomics, metabolomics, single-cell transcriptomics and combination of multi-omics technologies, etc so as to provide a reference for the researches on post-traumatic sepsis.

In recent years, the research on the anti-tumor effect of traditional Chinese medicine has been increasing year by year. Both the effective extracted ingredients of Chinese medicine and its compound preparations have significant efficacy and advantages in tumor treatment. Costunolide, the active ingredient of Aucklandia lappa (a traditional Chinese medicine), is a natural sesquiterpene lactone, which has a variety of pharmacological effects, such as anti-oxidation, anti-inflammation, hypoglycemic effect, anti-microbial effect etc. In recent years, more and more experimental studies in vivo and in vitro have shown that this component has anti-tumor activity, which can inhibit the growth of breast cancer, gastric cancer, melanoma cancer, prostate cancer, leukemia, liver cancer, lung cancer, ovarian cancer, esophageal cancer, colorectal cancer, osteosarcoma and other tumors. Its antitumor mechanism mainly lies in the regulation of PI3K/AKT/mTOR, AKT-MDM 2-p53, ROS-AKT/GSK-3β, Bcr / Abl, Stat5 and other signaling pathways, which affects reactive oxygen species, apoptosis-related proteins, autophagy-related proteins, and cyclin, and thus induces apoptosis, causes autophagy and arrests cell cycle in G2 / M phase, G1 phase, and S phase. In addition, the combination of costunolide with imatinib and doxorubicin can attenuate toxicity and enhance anti-tumor effect, and also reverse tumor drug resistance. By consulting and sorting out the relevant research literature at home and abroad, the author summarized the research progress of costunolide on the antitumor effect and mechanism, the combined drug use and the reversal of tumor drug resistance in order to provide theoretical basis for the development and utilization of new drugs of this ingredient.

Influenza viruses are a serious threat to human health and have a major impact on social development, making them a public health and safety hazard worldwide. Therefore, understanding the life cycle of influenza viruses can provide strategies for fighting viral infections. After influenza virus infection, host cells will defend themselves against the virus by activating the innate immune system. There is a close relationship between the virus and host factors, as host factors are required at each stage of the influenza virus life cycle and have different effects on virral proliferation. Polymerase basic protein 1 (PB1), an RNA polymerase subunit, is a key viral protein in influenza virus replication and transcription. This review summarized how different host factors interact with PB1 to regulate the replication, transmission and pathogenicity of influenza viruses, providing new ideas for the development of antiviral drugs.

Glucose-6-phosphate dehydrogenase (G6PDH) catalyzes the first and rate-limiting step of the oxidative pentose phosphate pathway, existing in both cytosolic and plastidic compartments of higher plants. Its main function is to provide reducing power (NADPH) and pentose phosphates for reductive biosynthesis and maintenance of the redox state of the cell. In addition, the expression of this enzyme is related to different biotic and abiotic stresses. In this review, we analyzed the isoenzyme, regulation and biological function of G6PDH. Meanwhile, we summarized the progress work of G6PDH involved in stress resistance, gene cloning, enzyme-deficiency and cluster analysis. Problems should be solved were also discussed.

Objective: To investigate the prospect of applying technology of ultra fine powder (UFP) to TCM powders for external use. Methods: The morphocytology between UFP of Cortex cinnamomi , compared with its common powder, was observed; physical parameters of the UFP particles and the penetrating amount of cinnamaldehyde, through rat skin in vitro was determined with an improved Franz diffuse cell. Results: The diameter of the UFP particles detected was small (D 50 =12.72?m). and a typical microscopic characters of Cortex cinnamomi powder was not observed. The Cortex cinnamomi UFP have good transdermal effects. There existed the linear relationship between penetrating amount of cinnamaldehyde and penetrating time. The highest penetrating rate (0.25mg/cm 2/h) was within the first hour in the beginning, and then the rate became lower and sustained. The accumulating transdermal amount of the UFP was 1.0mg/cm 2 totally in 8 hours. Conclusion: It indicated that UFP might have a fine respect, applied in cosmetic or drug preparations for external use.
