Objective:To explore the correlation between the ratio of C-reactive protein (CRP) to albumin (CAR) and the syndrome type of Wei-Qi-Ying-Xue in patients with severe coronavirus disease 2019 (COVID-19).Methods:A case-control study was conducted to select 63 severe patients with COVID-19 admitted to the Dongzhimen Hospital of Beijing University of Chinese Medicine from December 2022 to December 2023, including 50 severe cases and 13 critical cases. The clinical data of the patients were collected. According to the syndrome differentiation of Wei-Qi-Ying-Xue, there were 21 cases of Qi syndrome, 20 cases of Ying syndrome and 22 cases of Xue syndrome. The differences of CRP, ALB and CAR levels in patients with different Wei-Qi-Ying-Xue syndromes were compared. Spearman correlation test was used to test the correlation between CRP, ALB, CAR and the Wei-Qi-Ying-Xue syndrome type, and the receiver operating characteristic (ROC) curve was used to detect the diagnostic efficacy of CRP, ALB and CAR on the Wei-Qi-Ying-Xue syndrome type.Results:There was a statistically significant difference in the clinical classification of Western medicine among the three groups ( P<0.05). The CAR of the Ying group and the Xue group was higher than that of the Qi group ( P<0.05), while there was no statistically significant difference in age and comorbidities (all P>0.05). The CRP of the Xue group was higher than that of the Qi group ( P<0.05), and the ALB of the Ying group and the Xue group was lower than that of the Qi group (all P<0.05). Correlation analysis showed that there was a correlation between the Wei-Qi-Ying-Xue syndrome type and CRP, ALB and CAR ( P<0.05), among which CAR changed most significantly with the change of Wei-Qi-Ying-Xue syndrome type. ROC curve analysis showed that CRP, ALB and CAR had good diagnostic value for Qi syndrome and Xue syndrome ( P<0.05). The critical values of the diagnosis of Qi syndrome were 48.57 mg/L, 34.20 g/L and 2.97. The critical values of the diagnosis of Xue syndrome were 28.30 mg/L, 26.6 g/L and 5.96. Conclusions:CAR ratio is correlated with the Wei-Qi-Ying-Xue syndrome type of severe COVID-19 patients, and its level changes are in line with the evolution law of Wei-Qi-Ying-Xue syndrome. CAR≤2.97 is contributed to the diagnosis of Qi syndrome, and CAR>5.96 is contributed to the diagnosis of Xue syndrome. CAR may be an objective index related to the Wei-Qi-Ying-Xue syndrome type of severe COVID-19 patients.

Objective:To evaluate the value of age-adjusted Charlson comorbidity index (aCCI) in the clinical prognosis of sepsis and septic shock in the elderly, and to further explore the role of aCCI in evaluating the timing of Shenfu injection in elderly patients with septic shock.Methods:Clinical data of elderly patients with sepsis and septic shock in Dongzhimen Hospital of Beijing University of Chinese Medicine from January 1, 2019 to January 1, 2022 were retrospectively analyzed. With the median aCCI score of all samples as the cutoff value, the patients were divided into the low aCCI score group and high aCCI score group. The prognosis of elderly patients with septic shock and the application timing of Shenfu injection with aCCI score and sequential organ failure assessment (SOFA) were compared.Results:A total of 61 patients were included, including 31 patients in the high aCCI score group. The proportion of septic shock in elderly sepsis patients was lower in the low aCCI score group ( P < 0.05). The aCCI score (95% CI: 1.229-2.615; P< 0.01) was more valuable than SOFA score (95% CI: 1.035-1.607; P< 0.05) in predicting septic shock in elderly patients with sepsis. The 28-day survival rate in the low aCCI score group was higher than that in the high aCCI score group ( P < 0.05). Both the SOFA score (95% CI: 1.010-1.364) and the aCCI score (95% CI: 1.072-10.501) were independent factors affecting the 28-day survival rate. The use of Shenfu injection was associated with 28-day survival outcome in elderly patients with septic shock (95% CI: 0.012-0.788; P < 0.05). Conclusions:aCCI score is more effective than SOFA score in assessing the risk of shock in elderly patients with septic shock, and has a certain predictive value for the survival and prognosis of elderly patients with sepsis. Shenfu injection may be beneficial to the survival and prognosis of elderly patients with septic shock, but it needs to be further verified by large-scale prospective studies.

Objective:To analyze the mechanism of Danpi-Chishao in treatment of sepsis based on network pharmacology.Methods:The corresponding targets of Danpi-Chishao and sepsis were carried out through TCMSP database, OMIM database and Genecards database. Cystoscope 3.8.2 software was used to construct the " Chinese medicine-active components-target-disease" network diagram. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were carried out by DAVID database. Weisheng cloud platform was used to draw bubble map.Results:A total of 36 effective components of Danpi-Chishao was obtained, mainly including quercetin, kaempferol, baicalin, β-sitosterol, stigmasterol, paeoniflorin and so on. There were 96 potential common key targets between Danpi-Chishao and sepsis, such as prostaglandin-endoperoxide synthase 2 (PTGS2), transcription factor p65 (RELA), phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit gamma (PIK3CG), B-cell lymphoma 2 (BCL-2)-associated X (BAX), BCL-2, Caspase-3 (CASP3) with a degree value>4.9. The result of protein-protein interaction (PPI) network analysis showed that there were 10 important target proteins, including alpha serine/threonine-protein kinase (AKT1), interleukin-6 (IL-6), tumor necrosis factor (TNF), interleukin-1β (IL-1β), vascular endothelial growth factor A (VEGFA), cellular tumor antigen p53 (TP53), matrix metalloproteinase-9 (MMP9), CASP3, PTGS2, C-C motif chemokine ligand 2 (CCL2). The pathways obtained by GO and KEGG enrichment analysis included atherosclerosis pathway, advanced glycation end products (AGE)-receptor for advanced glycation end products (RAGE) signal pathway, cancer pathway, tumor necrosis factor signal pathway, hypoxia-inducible factor (HIF) signal pathway, IL-17 signal pathway and other pathway.Conclusions:The mechanism of the intervention effect of Danpi-Chishao on sepsis may be that the active components such as quercetin, kaempferol, paeoniflorin act on target proteins such as PTGS2, RELA, PIK3CG, BAX, BCL2, CASP3, and through TNF-related signal pathway, HIF-1 signal pathway, IL-17 signal pathway, etc. Nonetheless, the conclusion needs further experimental verification.

Objective:Animal models of sepsis are mainly established by cecal ligation and puncture which causes mixed bacterial infections in the abdominal cavity. However in internal clinic, sepsis is more common to be caused by respiratory bacterial infections. Therefore, it is necessary to establish animal models of sepsis caused by lung Infection.Methods:According to the concentration of Staphylococcus aureus (S. aureus) suspension and Pseudomonas aeruginosa (P. aeruginosa) suspension, Sprague Dawley (SD) rats were equally divided into 10 groups, including S-Cont group, S-0.75 group, S-1.5 group, S-3 group, S-6 group and P-Cont group, P-1 group, P-2 group, P-4 group, P-8 group. Rats in the control group were treated with normal saline nasal drip. Rats in each experimental group were infected by nasal dripping bacterial suspension with 0.75×10 8 CFU/ml, 1.5×10 8 CFU/ml, 3×10 8 CFU/ml, 6×10 8 CFU/ml of S. aureus suspension or 1×10 8 CFU/ml, 2×10 8 CFU/ml, 4×10 8 CFU/ml, 8×10 8CFU/ml P. aeruginosa suspension. Our study detected the body temperature (T), blood pressure (BP), heart rate (HR) of rats in each group before and after infection, as well as blood lactic acid (Lac) and procalcitonin (PCT) level after infection. The lung infections of rats in each group were observed by hematoxylin-eosin (HE) staining. Results:The blood pressure(BP) of S-1.5 group, S-3 group, S-6 group and P-8 group was lower than before infection (all P<0.05). The Lac and PCT of each S. aureus experimental group were higher than that of the S-Cont group (all P<0.01); and they showed an increasing trend with the increase of the bacterial suspension concentration ( P<0.05), except for the S-3 and S-6 group ( P>0.05). The Lac and PCT of each P. aeruginosa experimental group were higher than that of the P-Cont group (all P<0.01); and they showed an increasing trend with the increase of the bacterial suspension concentration (all P<0.05), except for the Lac in the P-4 group and P-8 group ( P>0.05). HE staining showed that different degrees of inflammatory infiltration can be seen in the lungs of the experimental rats in each group. Conclusions:Infection of rats by nasal dripping with 3×10 8 CFU/ml of S. aureus suspension or 4×10 8 CFU/ml of P. aeruginosa suspension could establish relatively stable rat sepsis model induced by lung bacterial infection, of which the former could also establish a relatively stable septic shock model.
