In accordance with the theory of'treating the skin diseases with the skin',skin-related Chinese medicinals are usually used for the treatment of skin diseases,which reflects the thinking mode of holistic syndrome differentiation and classification according to the manifestations in traditional Chinese medicine.With ying-yang theory as the principle of differentiation and treatment of diseases and based on the core pathogenesis of'yin-yang imbalance causing the manifestations of the skin'for the skin diseases,Chinese medical master XU AN Guo-Wei has used skin-related Chinese medicinals in the treatment of skin diseases and has given full play to their unique advantage by following the theory of'treating the skin diseases with the skin'and'balanced regulation of yin and yang'.In the clinical practice,allergic skin diseases were usually treated with Cicadae Periostracum plus Dictamni Cortex for dispelling wind and relieving itching,hypopigmentation related skin diseases were usually treated with Sojae Semen Nigrum skin plus Dictamni Cortex for dispelling wind and tonifying kidney,autoimmune skin diseases were usually treated with Moutan Cortex plus Lycii Cortex for nourishing yin,clearing heat and activating blood,and skin diseases associated with abnormal sebum secretion were usually treated with Mori Cortex plus Lycii Cortex for purging lung and nourishing kidney.Skin-related Chinese medicinals have the actions of expelling wind and promoting eruption of papules,tonifying kidney and nourishing yin.The medication method of'treating the skin diseases with the skin'will provide reference for the treatment of skin diseases.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the central mechanism of moxibustion in treating chronic inflammatory visceral pain(CIVP)and its analgesic effect from the perspective of the p38 mitogen-activated protein kinase(MAPK)/Ets-like transcription factor 1(ELK1)signaling pathway in the spinal cord. Methods:Clean-grade male Sprague-Dawley rats were randomly divided into a normal group,a model group,a herb-partitioned moxibustion(HPM)group,a sham-HPM group,a p38 MAPK inhibitor group,and a dimethyl sulfoxide(DMSO)group.CIVP rat models were prepared using an enema mixture of 2,4,6-trinitrobenzene sulfonic acid solution and 50%ethanol.The HPM group was treated with HPM;the sham-HPM group was treated the same as the HPM group,but the moxa cones were not ignited;rats in the p38 MAPK inhibitor group received L5-L6 intrathecal injection of p38 MAPK inhibitor(SB203580);rats in the DMSO group received L5-L6 intrathecal injection of 2%DMSO.Abdominal withdrawal reflex(AWR),mechanical withdrawal threshold(MWT),and thermal withdrawal latency(TWL)were used to observe pain-related behaviors in each group.Hematoxylin-eosin staining was used to observe the morphological changes in rat colon tissue.Western blotting and real-time quantitative reverse-transcription polymerase chain reaction were used to detect the phosphorylated protein and mRNA expression of apoptosis signal-regulating kinase 1(ASK1),MAPK kinase(MKK)3/6,p38 MAPK,ELK1,and mitogen and stress-activated protein kinase 1(MSK1)in the spinal cord. Results:Compared with the normal group,CIVP rats had severe colonic inflammatory injuries,and the pathological injury scores increased significantly,along with increased AWR scores under different colorectal distension(CRD)stimulation pressures and decreased MWT and TWL;the mRNA and phosphorylated protein expression of p38 MAPK,ELK1,MSK1,ASK1,MKK3,and MKK6 all increased in the spinal cord(P<0.01).After HPM treatment,the colon injuries were repaired,and the pathological injury scores decreased;under different CRD stimulation pressures,the AWR scores decreased,and the MWT and TWL increased;the mRNA and phosphorylated protein expression of p38 MAPK,ELK1,ASK1,and MKK3 in the spinal cord also decreased,with statistically significant differences compared with the model group and the sham-HPM group(P<0.01).There were no significant differences in the above indicators between the HPM group and the p38 MAPK inhibitor group(P>0.05),and the same was true regarding the comparisons between the model group and the DMSO group. Conclusion:HPM exerted analgesic effects via downregulating the mRNA and phosphorylated protein expression of ASK1,MKK3,p38 MAPK,and ELK1 in the spinal cord of CIVP rats.The inhibition of spinal p38 MAPK/ELK1 signaling pathway activation may be one of the mechanisms by which HPM relieves pain in CIVP.

Objective To explore the molecular mechanism of Yixin Tongbi Mixture in the intervention of atherosclerosis(AS).Methods Thirty-six SD rats were divided into the normal control group,model con-trol group,low dose Yixin Tongbi Mixture group,medium dose Yixin Tongbi Mixture group,high dose Yixin Tongbi Mixture group and atorvastatin group,6 cases in each group.Except the normal control group,the oth-er groups adopted the high fat vitamin D3 mixed feed gavage for constructing the rat AS model.The low dose,medium dose and high doses Yixin Tongbi Mixture groups were gavaged by 10,20,40 g/kg Yixin Tongbi Mixture.The atorvastatin group was gavaged by 5 mg/kg atorvastatin;and the normal control group and mod-el control group were gavaged by placebo once a day for consecutive 14 d.The pathological changes of aortic tissues were observed by HE staining.The levels of serum TC,TG,HDL and LDL were detected by automatic biochemical analyzer.The expression levels of IL-6,TNF-α and ICAM-1 in aortic tissue were detected by ELISA.The expression levels of MMP-2 and MMP-9 in aortic tissue and Bax and Bcl-2 protein expression lev-els in cardiac tissue were detected by Western blot.Results Compared with the normal control group,the aor-tic wall of the model control group rats was significantly thickened,and the levels of serum TC,TG,HDL and LDL were increased.The expression levels of MMP-2,MMP-9,IL-6,TNF-α and ICAM-1 in the aortic tissues were also increased.The expression level of Bax in the myocardial tissues was increased,while the expression level of Bcl-2 was decreased,and the differences were statistically significant(P＜0.05).Compared with the model control group,the above indicators in the medium dose and high doses Yixin Tongbi Mixture groups and atorvastatin group were significantly improved(P＜0.05).Except Bax,IL-6 and ICAM-1 expression lev-els,the other indicators in the low dose Yixin Tongbi Mixture group had no statistically significant differences(P＞0.05).Conclusion Yixin Tongbi Mixture could inhibit the AS occurrence and development by inhibiting inflammation and cellular apoptosis,and its mechanism is related to the abnormal expression of IL-6/TNF-αand MMP-2/MMP-9.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Myeloid-derived suppressor cells (MDSCs) are a group of immature and heterogeneous cells that can inhibit T cell function. In pathological conditions such as tumors, infections, and chronic inflammation, the large expansion of MDSCs is involved in processes of immune escape, immune tolerance and inflammatory reactions. MDSCs are also crucial in the pathophysiology of hepatitis B virus (HBV) infection, however, their activation, differentiation, and function during HBV infection are still unclear. This article reviews the general characteristics and roles of MDSCs in HBV infection, as well as related drug therapies, in order to provide information for further research on the related mechanism and potential targeted treatment.

Dry eye is a multifactorial disease, which seriously affect the work and life of patients. Since the pathogenesis of dry eye has not been clarified so far, there is no standard animal model available now. Non-Sjögren syndrome dry eye is one of the main types of dry eye, which requires further research. Studies on dry eye mechanisms have led to the development and improvement of animal models. In this paper, the methods of animal models of non-Sjögren syndrome dry eye, including drug treatments, surgery, exogenous injury, behavioral patterns, changes in diet, are reviewed. In addition,different models are described, the problems are analyzed and perspectives and reflections on future research are offered.

【Objective】 To understand the memory phenotype and function of SARS-CoV-2 reactive CD4+ T cells in healthy individuals. 【Methods】 In this study, SARS-CoV-2-derived peptides were used to stimulate PBMC from participants.SARS-CoV-2 reactive memory T cells were detected by intracellular staining and flow cytometry, and memory phenotype analysis was performed.CBA was used to detect cytokine secretion after SARS-CoV-2-derived peptides stimulation to evaluate the function of SARS-CoV-2 reactive memory T cells. 【Results】 We found that SARS-CoV-2 reactive CD4+ memory T cells could be detected in 40% (6/15) healthy donors.Phenotypic analysis of memory showed that these T cells were mainly composed of central memory T cells(82.2%), and other memory cells accounted for 17.8%.Compared with negative control, IL-10 was significantly decreased after stimulation of SARS-CoV-2-derived peptides (P<0.05), while the secretion of IFNγ, TNFα, IL-2 and IL-4 showed no significant difference. 【Conclusions】 SARS-CoV-2 reactive CD4+ memory T cells are present in healthy individuals from China.

Work-related musculoskeletal disorders (WMSDs) refer to musculoskeletal disorders caused by work or work as the main cause, which are characterized by high prevalence and heavy burden of disease as a global problem. The classification and catalog of occupational diseases is of great significance for guiding the prevention and control of occupational diseases and safeguarding the rights and interests of workers. The types of WMSDs included in the list of occupational diseases vary greatly from country to country, and the regulations on specific pathogenic factors are also inconsistent. By sorting out and analyzing the lists and characteristics of WMSDs at home and abroad, and using the International Statistical Classification of Diseases and Related Health Problems (ICD-10) in occupational health to standardize of WMSDs in various countries, which would lay the foundation for future multi-country WMSDs occupational health registration and disease burden research, and provide a reference for China to revise the WMSDs list.
