[Objective] To validate and optimize the platelet transfusion refractoriness (PTR) prediction model for patients with hematological disorders established by our center. [Methods] The data of patients with hematological diseases who received platelet transfusions from December 2021 to December 2022 were used as the training set, and data from January 2023 to December 2023 as the validation set. The validation set data was used to validate the predictive model constructed on the training set. Relevant risk factors for PTR were collected through literature review and preliminary studies。 The patients were divided into effective and ineffective groups according to the corrected count increment (CCI) of platelet counts. Predictive factors were screened using univariate and multivariate logistic regression. The calibration of the model were assessed via calibration curves, while discrimination, accuracy, sensitivity, and specificity were evaluated using receiver operating characteristic (ROC) curves Clinical utility was further analyzed with decision curve analysis (DCA). [Results] The Hosmer-Lemeshow (H-L) goodness-of-fit test for the validation set yielded S: P=0.000, indicating that the original model needs optimization. Baseline comparisons and logistic regression identified the number of red blood cell units (RBCU) and platelet units (PLT-U) transfused as key predictors for the optimized model. The H-L goodness-of-fit test S: P values for the training and validation sets were 0.930 and 0.056, respectively; the ROC areas were 0.793 5 and 0.809 4, specificities 90.95% and 84.21%, sensitivities 59.26% and 70.04%, and accuracies 78.14% and 74.10%, respectively. DCA demonstrated clinical net benefit within a prediction probability threshold range of 0.2-0.8. [Conclusion] Transfusion volumes of RBC-U and PLT-U were inversely associated with PTR in hematological patients. The resulting PTR prediction model exhibits moderate predictive efficacy and clinical benefit.

Objective To study the evaluation value of lung injury score(LIS)and advanced glycation end products(AGEs)expression levels on the prognosis of elderly patients with sepsis-related acute lung injury/acute respiratory distress syndrome(ALI/ARDS).Methods A total of 98 elderly patients with sepsis-related ALI/ARDS admitted to First Branch of the First Affiliated Hospital of Chongqing Medical University from March 2019 to April 2021 were selected as the research group,and the patients were divided into two sub-groups according to their survival within 30 d after admission:the survival group(55 cases)and the death group(43 cases).Another 51 elderly patients with non-ALI/ARDS sepsis admitted to First Branch of the First Affiliated Hospital of Chongqing Medical University in the same period were selected as the control group.After admission,the clinical data of patients were recorded,and the levels of serum creatinine,troponin I,B-type brain natriuretic peptide(BNP),serum C-reactive protein(CRP)and procalcitonin(PCT)were de-tected.Enzyme-linked immunosorbent assay was used to determine the levels of AGEs in patients'serum.The LIS score was evaluated by LIS scale.With clinical factors as independent variables and prognosis as dependent variables,Logistic regression curve was used to analyze the death factors of elderly sepsis-related ALI/ARDS patients.Results AGEs levels,LIS scores,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)scores decreased sequentially in the death group,survival group,and control group(all P<0.05).The levels of lactic acid,blood glucose,troponin I,PCT,BNP and CRP in arterial blood of patients in the death group were significantly higher than those in the survival group and the control group(P<0.05).The results showed that arterial lactate,blood glucose,troponin I,PCT,BNP,CRP,AGEs,APACHE Ⅱ score,and LIS score were all independent risk factors for mortality in elderly sepsis-related ALI/ARDS patients(P<0.05).The area under the curve(AUC)of LIS score predicting prognosis in elderly sepsis-related ALI/ARDS pa-tients was 0.857(95%CI:0.821-0.911),and AUC of serum AGEs was 0.861(95%CI:0.809-0.908).LIS score and AGEs level had certain predictive value for the prognosis of elderly sepsis-related ALI/ARDS pa-tients.Conclusion The LIS score and AGEs level of the elderly patients with sepsis-related ALI/ARDS are independent risk factors of death,which have important predictive value for prognosis.

Objective:To compare the effects of leukocyte-poor platelet-rich plasma (Lp-PRP) and leukocyte-rich platelet-rich plasma (Lr-PRP) on dorsal wound healing in rats.Methods:Thirty-six male Sprague-Dawley rats were randomly divided into Lp-PRP group, Lr-PRP group and control group, each containing twelve rats. Venous blood was drawn and the Lp-PRP and Lr-PRP were prepared separately using a centrifugal method. Circular full-thickness skin defect wounds (15 mm in diameter) were created on the backs of the rats in the three groups. The wounds were then treated with 100 μl Lp-PRP, Lr-PRP and saline, respectively. At 7 and 14 days post-operation, the wounds were photographed, and Image J software was used to calculate the wound area rate (postoperative wound area/wound area at modeling time × 100%). At 14 days post-operation, the total neo-epithelium length and collagen deposition rate of the wounds were evaluated using HE and Masson staining, respectively. At 7 days post-operation, the relative expression of vascular endothelial growth factor (VEGF) in the wounds was detected by Western blotting, and the number of CD31 positive microvessels in the wounds was examined by immunohistochemistry. Statistical analysis was performed using SPSS 28.0. One-way analysis of variance (ANOVA) was used to compare the three groups, and Tukey’s test was used for pairwise comparisons. A significance level of P<0.05 was considered statistically significant. Results:Blood analysis revealed that the platelet concentrations in the prepared Lp-PRP and Lr-PRP were 4.1 times and 4.5 times that of whole blood, respectively ( P<0.01), with no significant difference between the two PRPs ( P>0.05). The leukocyte concentration in Lp-PRP was undetectable, while in Lr-PRP, it was 3.5 times that of whole blood ( P<0.01). The wound area rate at 7 and 14 days post-operation, the total neo-epithelium length and collagen deposition rate at 14 days post-operation, as well as the relative expression of VEGF and the number of CD31-positive microvessels at 7 days post-operation in the Lp-PRP and Lr-PRP groups were superior to those in the control group (all P<0.01). However, there was no significant difference between the two PRP groups (all P>0.05). Conclusion:Both Lp-PRP and Lr-PRP promote dorsal wound healing in rats by enhancing re-epithelialization, collagen deposition, and angiogenesis. The impacts of Lp-PRP and Lr-PRP on promoting wound healing are comparable and not influenced by the presence of leukocytes in PRPs.

Based on the"You Gu Wu Yun"theory in traditional Chinese medicine(TCM),this paper believes that"Gu"in"You Gu Wu Yun"is extended to"state"from the perspective of"TCM state".In order to avoid the adverse reactions of TCM,the macro,meso,and micro three views should be used together,and macro,meso,and micro parameters should be integrated.We should also carefully identify the physiological characteristics,pathological characteristics,constitution,syndrome,and disease of human body by combining qualitative and quantitative method,highlighting the relationship between the prescription and the"state".The correspondence between prescription and the"state"will reduce the risk of adverse reactions of TCM.In this paper,we hope to focus on the guiding role of the"You Gu Wu Yun"theory in TCM research,to give full play to the characteristics and advantages of TCM,and to dialectically treat the role of TCM.

The correspondence between prescription and syndrome is the advantage and characteristic of traditional Chinese medicine(TCM)treatment.However,the pathogenesis of clinical diseases is complex and the condition is changeable,and the clinical application is difficult to achieve the maximum effect under the existing cognition of the correspondence between prescription and syndrome.In this paper,the five categories of physiological characteristics,pathological characteristics,constitution,syndrome,and disease of the longitudinal classification of"TCM state"are introduced into the correspondence of prescription and syndrome.Under the vertical perspective of"TCM state",the theoretical connotation of the correspondence between prescription and syndrome is interpreted as"correspondence between prescription and state",namely correspondence of"prescription-physiological characteristics",correspondence of"prescription-pathological characteristics",correspondence of"prescription-constitution",correspondence of"prescription-syndrome",and correspondence of"prescription-disease".It is hoped to accurately grasp the corresponding connotation of the correspondence between prescription and syndrome,in order to deepen the clinical thinking mode of TCM.
