Objective:To investigate the features of peripheral blood lymphocyte subsets in children with sepsis and evaluate the value of these cells in combination with multiple indicators in the diagnosis of pediatric sepsis.Methods:A retrospective study was conducted on 86 sepsis children and 83 children with local infection admitted to Hebei Children′s Hospital from October 2022 to October 2024. Baseline clinical data, peripheral blood lymphocyte subsets, and other laboratory indicators were compared between the two groups. The least absolute shrinkage and selection operator (LASSO) regression and multivariate logistic regression were used to evaluate the independent risk factors correlated with the initiation of sepsis. The receiver operating characteristic (ROC) curve was plotted to evaluate the value of each independent risk factor for diagnosing sepsis.Results:The thrombin time, the absolute counts of NK, CD3 + T, CD4 + T, and CD8 + T cells, the levels of IgG and IgM, and the counts of lymphocytes and platelets were lower in the sepsis children than in the children with local infection. However, the prothrombin time (PT), activated partial thromboplastin time, the levels of fibrinogen, direct bilirubin, and C-reactive protein (CRP) were higher in the sepsis group (all P<0.05). The variables screened by LASSO regression were analyzed by the multivariate logistic regression, and the results showed that PT, absolute CD4 + T cell count, and the levels of IgM and CRP were independent risk factors for sepsis. The ROC analysis indicated that the area under the ROC curve (AUC) for PT, absolute CD4 + T cell count, and IgM and CRP levels when used individually in diagnosing sepsis was 0.729, 0.593, 0.605, and 0.795, respectively. The AUC for the four indexes when used in combination for diagnosing sepsis reached 0.822, showing greater superiority over that of the single index. Conclusions:The combined measurement of PT, absolute CD4 + T cell count, and the levels of IgM and CRP can improve the diagnostic efficacy for sepsis in children. Early monitoring of these indexes facilitates the assessment of the condition in children suffering from sepsis.

This paper summarized the clinical experience of Prof. LI Diangui in treating gastroesophageal reflux disease （GERD） based on the theory of turbidity-toxin in liver. It is believed that internal accumulation of turbidity-toxin and liver depression with stomach counterflow are the main pathogenesis of GERD， and thus the therapeutic methods of resolving turbidity and resolving toxins， regulating the liver and harmonizing the stomach are proposed. In clinical practice， GERD is divided into the early stage， middle stage and late stage. For the early stage， the modified Huazhuo Shugan Hewei Formula （化浊疏肝和胃方） is used to regulate qi and remove turbidity， soothe the liver and harmonize the stomach； for the middle stage， the modified Huazhuo Qingre Zhisuan Formula （化浊清热制酸方） is applied to clear heat， direct the turbid downward， and resolve toxins； for the late stage， the modified Yiwei Decoction （益胃汤） is adopted to replenish qi， nourish yin and simultaneously resolve turbidity-toxin. Throughout the treatment process， attention should be paid to protecting the spleen and stomach， and the medication could be modified according to changes of individual condition.

Objective:To develop a Knowledge-Attitude-Practice (KAP) Scale for Dietary Management During Hemodialysis and to test its reliability and validity.Methods:Based on the KAP theoretical framework, an initial version of the scale was developed through a literature review and expert consultations. A convenience sampling method was used to recruit hemodialysis patients from four hospitals in Suzhou in March 2024. Questionnaire item analysis and reliability and validity tests were conducted.Results:A total of 460 questionnaires were distributed and 438 valid responses were collected, with an effective response rate of 95.22%. The final scale included three dimensions (knowledge, attitude, and practice) with 34 items. Content validity at the scale level was 0.910, and the item level ranged from 0.800 to 1.000. Exploratory factor analysis extracted three common factors, with a cumulative variance contribution rate of 74.520%. Confirmatory factor analysis showed a good model fit. The total Cronbach's α coefficient of the scale was 0.971, and the Cronbach's αcoefficients for the three dimensions were 0.963, 0.933, and 0.934, respectively. The test-retest reliability coefficient was 0.839.Conclusions:The Knowledge-Attitude-Practice Scale for Dietary Management During Hemodialysis demonstrates good reliability and validity, making it a valuable tool for assessing the KAP level of dietary management in hemodialysis patients.

As people age, older adults experience problems such as aging and degeneration of systemic organs and skin barrier function, leading to a high incidence of dry skin and pressure injuries. Dry skin and pressure injuries interact with each other to exacerbate the failure of skin function, which not only increases suffering, mortality risk, and medical costs for the elderly but also places a heavy burden on society and families. This paper summarizes the epidemiological characteristics of dry skin in the elderly and its influencing factors, the impact of dry skin in the elderly on pressure injuries, and puts forward the prevention and control strategies of "external treatment" and "internal nourishment" to provide a reference for the development of prevention and control strategies for dry skin and pressure injuries in the elderly in China.
