Objective:To investigate the risk factors for lower extremity deep vein thrombosis (DVT) in patients with bone trauma and their diagnostic efficacy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 108 patients with bone trauma who were admitted to Affiliated Changzhou Second People′s Hospital of Nanjing Medical University from October 2023 to February 2024, including 61 males and 47 females, aged 17-96 years [(55.2±19.5)years]. Based on the results of color Doppler ultrasonography of lower extremities within 96 hours on admission, the patients were divided into DVT group ( n=58) and non-DVT group ( n=50). In DVT group, 42 patients developed lower extremity DVT within 7 days after trauma and the other 16 patients developed lower extremity DVT after 7 days. Basic clinical data including gender, age, body mass index (BMI), underlying diseases, cause of injury, site of fracture, surgery and admission Caprini score, and admission laboratory test indicators including routine coagulation indicators [prothrombin time (PT), international normalized ratio (INR), thrombin time (TT), activated partial thromboplastin time (APTT), fibrinogen (FBG) and D-dimer (D-D)] and four thrombosis indicators [plasma thrombin-antithrombin III complex (TAT), thrombomodulin (TM), tissue-type plasminogen activator-inhibitor 1 complex (tPAIC) and plasmin-alpha2-plasmin inhibitor complex (PIC)] were collected in the two groups. Univariate analysis and multivariate binary Logistic regression analysis were conducted to investigate the correlation between these indicators and incidence of lower extremity DVT in patients with bone trauma and determine the independent risk factors. Receiver operating characteristic (ROC) curve and area under the curve (AUC) of the relevant risk factors were analyzed to evaluate and compare the diagnostic efficacy of the factors for lower extremity DVT in patients with bone trauma and further assess the diagnostic efficacy of the factors for lower extremity DVT within 7 days after bone trauma. Results:Univariate analysis revealed significant correlations of gender, age, Caprini score, D-D, TAT, TM and PIC with incidence of lower extremity DVT in patients with bone trauma ( P<0.01). The results of multivariate binary Logistic regression analysis demonstrated that Caprini score ( OR=1.36, 95% CI 1.12, 1.65, P<0.01), TAT ( OR=1.05, 95% CI 1.00, 1.10, P<0.05), and TM ( OR=1.34, 95% CI 1.02, 1.77, P<0.05) were significantly correlated to incidence of lower extremity DVT in patients with bone trauma. ROC curve analysis indicated that TAT (AUC=0.76, 95% CI 0.67, 0.86) had the highest diagnostic efficiency, followed by TM (AUC=0.72, 95% CI 0.62, 0.81) and Caprini score (AUC=0.72, 95% CI 0.62, 0.82). The combined analysis of all the factors effectively enhanced the diagnostic efficiency for DVT (AUC=0.84, 95% CI 0.77, 0.92). Additionally, TAT (AUC=0.81, 95% CI 0.71, 0.91) demonstrated better diagnostic efficacy for lower extremity DVT within 7 days after bone trauma compared with the Caprini score (AUC=0.72, 95% CI 0.61, 0.83) and TM (AUC=0.71, 95% CI 0.60, 0.83). Similarly, the combined analysis of all the factors also effectively enhanced the overall diagnostic efficacy for lower extremity DVT within 7 days after bone trauma (AUC=0.85, 95% CI 0.77, 0.93). Conclusions:Caprini score, TAT and TM are identified as independent risk factors for lower extremity DVT in patients with bone trauma, and all the three factors demonstrate good diagnostic efficacy. Their combination is found to have statistically significant higher diagnostic efficiency than each individual factor. Furthermore, TAT is proved to be the best in diagnosing lower extremity DVT within 7 days after bone trauma, while the combined analysis of all the risk factors can further improve the diagnostic efficacy.

Objective: To explore the efficacies of regimens of three-drug induction therapy (ATRA+ATO+anthracyclines) versus two-drug induction therapy (ATRA+ATO) in patients with acute promyelocytic leukemia (APL). Methods: Of 184 patients diagnosed with APL from January 2009 to March 2016, 58 patients underwent three-drug induction therapy, while the rest were treated with two-drug induction therapy. Three-drug induction therapy was of ATRA (20 mg·m^-2·d^-1, d_1-28) + ATO (0.16 mg·kg^-1·d^-1, d_1-28) + Idarubicin (8 mg·m^-2·d^-1, d_3-5) /daunorubicin (40 mg·m^-2·d^-1, d_3-5) , while two-drug induction therapy ATRA+ATO with the same doses and methods as above. Of 184 cases, 69 cases accompanied with WBC counts>10×10⁹/L, 115 cases with WBC counts≤10×10⁹/L at onset. Results: ①Short-term efficacy: After one cycle induction therapy, the rates of hematologic remission, genetic remission, molecular remission and induced differentiation syndrome (DS) in three-drug regimen group were 98.3%, 87.9%, 72.4% and 0 respectively, while those in two-drug regimen group were 87.3%, 65.9%, 51.6% and 12.7% respectively. In patients with WBC >10×10⁹/L, DS rate and early mortality in three-drug regimen group were lower than in two-drug regimen group (0 vs 15.6%, 4.2% vs 15.6%, respectively). In patients with WBC≤10×10⁹/L, DS rate in three-drug regimen group was also lower than in two-drug regimen group (0 vs 12.3%) , but there were no statistical differences in terms of relapse and early mortality. ② Long-term efficacy: The relapse rate, overall survival (OS) and disease free survival (DFS) in three-drug regimen group were 0, 98.5%, 96.6% respectively, while those in two-drug regimen group were 8.6%, 86.5% and 84.1% respectively; the advantages of three-drug over two-drug regimen, especially in cases of WBC >10×10⁹/L were observed. ③ Side effects: the incidences of gastrointestinal reaction, liver dysfunction, myocardial damage and headache in three-drug regimen group hardly increased. Conclusion The efficacies of three-drug induction therapy were superior to two-drug one.

Hepatitis E virus(HEV)is one of the most common pathogens in acute viral hepatitis.There are at least eight distinct genotypes of HEV.Only humans can contract HEV genotypes 1 and 2,but zoonotic viruses like genotypes 3 and 4 are mostly spread by eating undercooked or in-fected pork in some affluent nations.As a result,boars,both domestic and wild,are typically regar-ded as primary hosts of HEV.Nevertheless,during the past few years,a growing body of research has demonstrated that a number of other wild ruminant animals,such as wild deer and goats,are also susceptible to HEV infection.Determining their participation in the epidemiological cycle of hepatitis E thus requires an understanding of the risk variables that influence the transmission be-tween wild ruminants and humans.With an emphasis on published serological and molecular re-search,this review offers a broad summary of the body of knowledge currently available on the epi-demiology of HEV in wild ruminants.It addresses potential risk factors that could impact the spread of HEV among animals as well as their potential to serve as a source of infectious zoonotic illnesses.It presents an overview of the most recent developments in the epidemiology of HEV in wild ruminants and offers a framework for HEV prevention and management based on science.

To identify the intestinal roundworms of Eclectus roratus and Psittacula alexandri from the Guangdong region by morphological analysis and molecular biology techniques,and to amplify the mitochondrial genome of parrot roundworms using PCR,as well as to carry out phylogenetic analyses based on the sequences of their mitochondrial genes.The results showed that the parrot roundworms identified in this identification belongs to Ascaridia.nymphii and its mitochondrial genome consists of 12 protein coding genes,22 tRNA genes,2 ribosomal RNA genes and two non-coding regions.Phylogenetic analyses showed that A.nymphii identified in this study is located in the same evolutionary branch as the previously reported Ascaridia sp.,is closely related and con-stitutes a separate clade of avian ascarids with pigeon roundworms and chicken roundworms.This study provides important data for the classification,molecular epidemiology and population genetic evolution of parrot roundworms.
