Objective To compare multiple models and analyze SHAP feature contributions to construct a machine learning risk prediction model for post-reperfusion syndrome (PRS) during adult living donor liver transplantation (LDLT). Methods Clinical data of 390 patients who underwent LDLT due to end-stage liver disease at the First Affiliated Hospital of Anhui Medical University from May 2023 to April 2025 were collected. Five machine learning models, including random forest, logistic regression, XGBoost, decision tree, and AdaBoost, were compared. Feature selection was performed using Lasso regression, and the training set was divided into five folds for stratified cross-validation. The generalization ability of the model was evaluated on the independent test set. The models were comprehensively compared based on key evaluation indicators such as recall rate, accuracy rate, precision rate, area under the curve (AUC) and F1 value, to determine the optimal model. Results Eight potential factors for predicting PRS were selected. The random forest model demonstrated the best prediction performance in both the training set and the test set. Its accuracy rate was as high as 84.2% (AUC = 0.894, 95% confidence interval 0.808-0.964) in the test set. The importance ranking of PRS predictors was determined through SHAP value analysis. Cold ischemia time, K⁺ during the anhepatic period and the model for end-stage liver disease (MELD) score were all identified as the most significant predictors. Conclusions Based on eight key indicators including cold ischemia time, portal vein occlusion time, pre-reperfusion body temperature, alkaline reserve during the anhepatic period, K⁺ during the anhepatic period, MELD score, left ventricular end-diastolic diameter and graft volume to standard liver volume ratio, the PRS prediction model constructed using the random forest algorithm demonstrates the best prediction performance in the test set, providing certain assistance for subsequent clinical predictions.

The classical latent structure method does not consider the influence of primary and secondary symptoms,syndromes and symptoms in the analysis and modeling of syndromes.In this paper,based on the data of damp-heat in intestine and stomach syndrome involving 1087 diabetic patients,the classical latent structure analysis was used to obtain the quantitative syndrome diagnostic rules.Then,using Constrained Latent Tree Analysis(CLTA),the quantitative syndrome diagnostic rules containing primary and secondary symptoms were obtained as follows,primary symptoms include halitosis(2.3),yellow tongue coating(2),abdominal distension(2.3),greasy tongue coating(2.1),loose stool or loose stool(1.5),red tongue(1.3),smooth pulse(1.4).Secondary symptoms include epigastric distension(1.1).Compared with the traditional latent structure analysis method,the rules established by CLTA are more compatible with the concept of differentiating primary and secondary symptoms and the common practice of TCM.The quantitative syndrome diagnostic rules of damp-heat in intestine and stomach syndrome constructed by the CLTA method have considerable objectivity in the modeling process.The diagnostic rules established were also compatible with the qualitative concept of TCM theory in stratifying primary and secondary symptoms.Finally,the diagnostic rules are obtained by logistic regression analysis,and the accuracy of the three rules is compared.The results show that the rule recognition accuracy obtained by CLTA is the highest.Therefore,the syndrome diagnostic rules of damp-heat in intestine and stomach obtained from the analysis of CLTA are in line with the constraint semantics of primary and secondary diseases and the theory of traditional Chinese medicine.

Objective To investigate the infection status and clinical parameters of human metapneumovirus(HMPV)in children with acute respiratory tract infections in Jianyang area.Methods A total of 2 669 hospitalized children with acute respiratory tract infec-tions at Jianyang People's Hospital from March 2023 to February 2024 were enrolled.Thirteen kinds of respiratory pathogens were de-tected using multiplex PCR and capillary electrophoresis.The clinical data of HMPV-infected children were collected and analyzed.Re-sults Out of 2 669 children with acute respiratory tract infections,209 were detected with HMPV,with a positive rate of 7.83%.HMPV-positive children were mainly concentrated in under 5 years old(73.21%),with cough,fever,wheezing,and shortness of breath as main clinical manifestations.The rate of single HMPV infection was 58.85%,and those of mixed bacterial infection and mixed viral infection were 26.69% and 13.88%,respectively.The levels of white blood cells(WBC),lymphocytes(LYM),platelets(PLT),C-reactive protein(CRP),alanine aminotransferase(ALT),aspartate aminotransferase(AST),lactate dehydrogenase(LDH),troponin I(cTn I),and procalcitonin(PCT)in the mixed infection group were significantly higher than those in the single HMPV infection group(P＜0.05),while the levels of hemoglobin(Hb),total protein(TP),and creatinine(Cr)were significantly lower than those in the single HMPV infection group(P＜0.05).Compared with the non-severe pneumonia group,the levels of WBC,Hb,PLT,and CRP in the severe pneumonia group were significantly increased(P＜0.05).Multivariate Logistic regression analysis showed that age＜3 years,co-infection,and CRP≥20 mg/L were risk factors for severe HMPV pneumonia(P＜0.05).Conclusion HMPV is one of the important pathogens causing acute respiratory tract infections in children in Jianyang area.The elevated levels of some laboratory indicators are associated with the severity of infection.Early and comprehensive bacteriological testing and detection of inflammatory markers are beneficial for guiding clinical treatment.

Starting from the intrinsic relationship between the glymphatic system and the core pathogenesis of vascular cognitive impairment （VCI）， including internal dampness， phlegm turbidity， and blood stasis， this paper explores clinical approaches to the diagnosis and treatment of VCI. Dysfunction of the kidney's role in governing water leads to the accumulation of dampness， phlegm turbidity， and blood stasis， which are key pathological mechanisms underlying the onset and progression of VCI. The glymphatic system participates in the circulation of cerebrospinal fluid within the central nervous system， and its impairment can result in reduced clearance of soluble metabolic waste products in the brain， a crucial factor contributing to VCI. It is proposed that the "kidney governing water" function is related to the glymphatic system， and that the cerebral collaterals correspond structurally to the glymphatic pathways. Clinically， therapies aimed at tonifying the kidney， resolving phlegm， activating blood circulation， and unblocking collaterals， such as modified Kaixin Powder （开心散）， which eliminates dampness and turbidity， transforms phlegm， restores consciousness， enhances cognition， and strengthens the brain， are commonly employed. These treatments may improve VCI prognosis by regulating glymphatic system function， providing a theoretical basis for the prevention and treatment of VCI with traditional Chinese medicine.
