Objective To explore the correlation between different syndromes of sepsis and laboratory parameters,SOFA score,and APACHE Ⅱ score,providing reference for improving the objectivity of traditional Chinese medicine syndrome differentiation.Methods Based on the cross-sectional survey,information of the four diagnostic methods of traditional Chinese medicine,laboratory parameters,and disease assessment scales were collected from sepsis patients admitted to ICUs in 8 hospitals across the country.ANOVA,non-parametric tests,and Logistic regression analysis were used to screen for sepsis syndrome related factors.Results A total of 905 sepsis patients were included,and the distributions of traditional Chinese medicine syndromes were as follows:163(18.01%)of phlegm heat obstructing the lungs syndrome,141(15.58%)of blood stasis and toxin obstruction(damage)syndrome,130(14.36%)of intense exuberant heat toxin syndrome,129(14.25%)of Yin exhaustion and Yang deficiency syndrome,124(13.70%)of Yangming fu-organ excess syndrome,96(10.61%)of lung Qi deficiency syndrome,68(7.51%)of Yin deficiency and internal heat syndrome,and 54(5.97%)of Qi and blood deficiency syndrome.The results of ANOVA and non-parametric tests showed that there were differences in 14 indicators,including body temperature,heart rate,WBC,NE%,PCT,CRP,PLT,D-D,APTT,Lac,HCT,Hb,SOFA score,APACHE Ⅱ score among 8 common syndromes(P<0.05);Using the 14 indicators mentioned above as independent variables,and syndrome as the dependent variable,Logistic regression analysis was conducted.The results showed that in the excess syndrome category:①Phlegm heat obstructing lung syndrome was positively correlated with heart rate and WBC,and negatively correlated with Lac and APACHE Ⅱ scores;②Intense exuberant heat toxin syndrome was positively correlated with body temperature,WBC,NE%,PCT,CRP,and negatively correlated with PLT and SOFA scores;③Yangming fu-organ excess syndrome was positively correlated with body temperature and negatively correlated with PCT;④Blood stasis and toxin obstruction(damage)syndrome was positively correlated with body temperature,NE%,PLT,CRP,and D-D,and negatively correlated with heart rate,WBC,PCT,and APTT.Deficiency syndrome category:①Lung Qi deficiency syndrome was positively correlated with Hb,and negatively correlated with body temperature,WBC,and HCT;②Yin deficiency and internal heat syndrome were negatively correlated with NE%and CRP;③Qi and blood deficiency syndrome was positively correlated with APACHE Ⅱ score,and negatively correlated with body temperature,Hb,PLT,D-D;④Yin exhaustion and Yang deficiency syndrome was positively correlated with heart rate,PCT,Lac,SOFA score,and APACHE Ⅱ score,and negatively correlated with body temperature.Conclusion Patients with sepsis with excess syndrome category have higher WBC,NE%,PCT,CRP scores,which suggests a drastic inflammatory response.Among them,Blood stasis and toxin obstruction(damage)syndrome have highest PLT,D-D,and lowest APTT,suggesting a more severe disorder of coagulation function.Deficiency syndrome category,especially patients with Yin exhaustion and Yang prostration syndrome has higher Lac and SOFA score and APACHE Ⅱ score than other patients with sepsis of other syndromes,suggesting a worse condition and poor prognosis.

Due to the difficulty of overcoming the abnormal epidermal barriers and addressing S. aureus infections without disrupting indigenous skin microbiota, effective treatment of bacterial infection atopic dermatitis (AD) remains a significant clinical challenge. Skin microbiota-derived extracellular vesicles (EVs) shows protentional for skin disease treatment, but the lack of antimicrobial activity and limited skin penetration hamper their application in bacterial infection AD treatment. Here, we developed novel nanoantibiotics by loading Lev into S. epidermidis-derived EVs (Lev@SE-EVs), with supreme antimicrobial activity, regulating epidermal immune responses and enhanced epidermal barrier functionality. The nanoantibiotics were further integrated into hyaluronic acid-based microneedle (MN) for efficient transdermal delivery of therapeutic agents and effectively treating bacterial infection in AD. Upon insertion into the skin, the rapidly released Lev@SE-EVs from MN are uptake by S. aureus in a selective manner, fibroblasts, and surrounding immune cells to exert therapeutic effects in the infected dermal layer, resulting in mitigated skin inflammation, reduced S. aureus burden and increased dermis repair. Notably, Lev@SE-EVs induce IL-17A⁺ CD8⁺ T-cell accumulation in the skin in an unrelated inflammation manner, which may represent heterologous protection. This EVs-integrated MN assisted Lev@SE-EVs to alleviate skin inflammation, repair skin, and provide an effective and safe therapeutic approach for bacterial infection AD treatment.

Objective:To investigate the promoting effect of individualized instruction combined with a blended learning model (IIBLM) in continuing training of neurology.Methods:A total of 93 trainees who received continuing training in Department of Neurology, The First Affiliated Hospital of Sun Yat-sen University, from August 2022 to December 2024 were enrolled as subjects. The 50 trainees registered since January 2024 were enrolled as observation group and received IIBLM teaching, including sub-specialty modular training, a cycle-adaptive cultivation system, a "mutual-selection" mentorship program, an on/off-line dual-track curriculum system, a dynamic course allocation mechanism based on "mutual selection", and a competency growth evaluation system, while the 43 trainees registered before January 2024 were enrolled as control group and received traditional teaching. A questionnaire survey and comprehensive competency assessments were performed to evaluate the effect of teaching, and the t-test, the chi-square test, and the qualitative analysis were used for statistical analysis. Results:Compared with the control group, the experimental group showed systematic improvements in clinical contents, theoretical curriculum, faculty competency, and workflow arrangement during continuing training, with a significant difference in the score of workflow arrangement between the two groups [(9.58±0.67) vs. (9.07±1.44), t=-2.13, P=0.037]. The observation group had a score of (97.70±1.30) for dynamic course allocation, an overall satisfaction rate of 97.15%, and a course benefit rate of 97.55%. The qualitative analysis showed that the trainees in the control group mainly complained of course monotony, while those in the observation group expected to enhance interdisciplinary integration and the cultivation of scientific research abilities. In addition, the results of competency assessment showed a continuous improvement in teaching effect after reform, with no significant difference. Conclusions:IIBLM teaching effectively enhances professional qualities, clinical competency, and the degree of satisfaction with courses among the trainees receiving continuing training, and it also revealed the necessity of interdisciplinary collaborative teaching and the integration of research and clinical practice.
