Objective:To investigate whether repeated tirofiban injections can continuously inhibit platelet aggregation in the arterial duct and affect its closure in neonatal canines.Methods:Four 24-month-old pregnant beagles underwent cesarean sections in two batches (two dogs per batch) 1-2 days before the expected delivery date at the Xuzhou Medical University Animal Experiment Center. The first litter of 21 neonates served as the control group (receiving 10 ml/kg normal saline) and were randomly divided into 1-h ( n=7, injected immediately after birth), 4-h ( n=7, injected at 0 h and 2 h after birth), and 12-h subgroups ( n=7, injected at 0 h, 2 h, 4 h, 6 h, 8 h, and 10 h after birth). The second litter of 18 neonates served as the experimental group (receiving 10 ml/kg tirofiban) with identical subgroup assignments ( n=6 per subgroup). Echocardiography was performed at 1 h, 4 h, and 12 h after birth to measure arterial duct inner diameter, maximum shunt velocity, and left atrial diameter/aortic root diameter (LA/Ao) ratio. Plasma platelet-derived growth factor (PDGF) was detected by enzyme-linked immunosorbent assay, while platelet membrane glycoprotein Ⅱb-Ⅲa in the arterial duct was assessed by Western blot and immunohistochemistry. Data were analyzed using t-tests, one-way ANOVA, Chi square tests, or Fisher's exact test. Results:No significant bleeding tendency occurred in either group. Two control neonates (one each in the 4-h and 12-h subgroups) died. In both control and experimental 1-h subgroups, all arterial ducts remained open, with no significant differences in ductal diameter, shunt velocity, or LA/Ao between groups (all P>0.05). In the 4-h subgroups, all experimental neonates had patent ducts arteriosus, while two controls exhibited closure; the experimental group had larger ductal diameters [(1.05±0.05) vs. (0.55±0.44) mm, t=－2.75, P<0.05)] and higher LA/Ao ratios (1.31±0.09 vs. 1.14±0.03, t=－4.90, P<0.05), but lower maximum shunt velocities [(107.06±17.47) vs. (153.74±12.78) cm/s, t=4.54, P=0.002). In the 12-h subgroups, all the controls had closed arterial ducts, while four of six experimental neonates exhibited closure, though the difference in closure rate was not statistically significant (6/6 vs. 4/6, Fisher's exact test, P=0.455). Plasma PDGF and glycoprotein Ⅱb-Ⅲa levels did not differ between two 1-h subgroups (all P>0.05). However, the 4-h and 12-h experimental subgroups showed lower PDGF levels [(373.5±13.1) vs. (880.3±80.2) pg/ml, t=10.81; (356.7±35.0) vs. (1 111.2±125.3) pg/ml, t=9.74; both P<0.05] and reduced glycoprotein Ⅱb-Ⅲa expression (0.32±0.07 vs. 0.80±0.23, t=3.29; 0.42±0.07 vs. 0.92±0.26, t=3.24; both P<0.05) compared to controls. Conclusion:Repeated tirofiban injections sustainably inhibit platelet aggregation in the arterial duct of neonatal canines and delay ductal closure, suggesting that intraductal platelet aggregation may be one factor influencing this process.

Spinal surgical site infection (SSI), especially deep SSI after internal fixation is difficult in treatment, with long course of disease and poor prognosis. At present, there are many controversies in the diagnosis and treatment of spinal SSI, with unsatisfactory overall efficacy of its diagnosis and treatment. Besides, no diagnosis and treatment guideline based on evidence-based medicine has been in existence. To this end, the Spinal Infection Group of the Orthopedic Branch of the Chinese Medical Doctor Association and the Spinal Infection Group of the Spinal Surgery Branch of the Chinese Rehabilitation Medicine Association jointly organized relevant experts to formulate Evidence-based clinical guideline for the diagnosis and treatment of surgical site infection in spinal trauma ( version 2024) based on an evidence-based approach. A total of 10 recommendations were proposed on the diagnosis and treatment of spinal SSI, so as to provide a clinical reference for the diagnosis and treatment of spinal SSI.

Methods: The median sagittal diameter and transverse diameter of the spinal canal from C2 to C7 were measured on CT images. The ratio of the median sagittal diameter to the transverse diameter was calculated. Accordingly, the spinal canal shape of each segment was classified into four, and the specific criteria of lunar phase classification were determined through linear discriminant analysis based on the ratio of the median sagittal diameter to the transverse diameter. The inter-rater reliability of the classification was explored using Kappa coefficients. Finally, the morphology of the different segments of the cervical spinal canal in healthy volunteers was revised and compared. Results: According to the ratio of the median sagittal diameter and the transverse diameter of the cervical spinal canal, the lunar phase classification of the cervical bony spinal canal was determined as follows: full-moon >0.65, 0.55< convex-moon ≤0.65, 0.46≤ quarter-moon ≤0.55, and residual-moon <0.46. The Kappa values of C2–C7 were 0.851, 0.958, 0.823, 0.927, 0.793, and 0.946, and the Kappa value of all C2–C7 segments was 0.854 that mainly presented two forms of full-moon (76.5%) and convex-moon (23.0%). A quarter-moon spinal canal was mainly distributed in C3, C4, C5, and C6; a residual-moon spinal canal was mainly distributed in C4 and C5; and the morphological distribution of C4 and C5 were similar (p>0.05). The frequency of the spinal canal of the residual-moon type was the highest, and the full-moon (6.5%) and residual-moon (7.5%) types of C7 were rare. Conclusions The morphological classification of the cervical spinal canal was established to present anatomical variations. The classification showed good inter-rater reliability.

Objective:To explore the mechanisms and clinical manifestations of disseminated intravascular coagulation (DIC) caused by exertional heat stroke.Methods:Analyze the clinical data of a patient with exertional heat stroke in Yichang Central People's Hospital and review relevant literature to evaluate the association between heat stroke and DIC, summarizing clinical presentations and laboratory findings.Results:The patient exhibited symptoms such as high fever and altered consciousness after engaging in intense labor in a high-temperature environment. Laboratory tests showed a platelet count of 43×10 9/L, D-dimer level of 5.3 mg/L, and prothrombin time of 21.8 s, which are consistent with a diagnosis of DIC. Following prompt cooling, fluid resuscitation, appropriate anticoagulant, goal-directed replacement therapy and supportive therapy, the patient’s condition gradually improved. Conclusion:Exertional heat stroke can lead to DIC, and clinical attention should be paid to its early recognition and intervention. Effective coagulation management and timely anticoagulant and supportive therapy are crucial for improving prognosis.

Objective:To analyze the clinical diagnosis, treatment ，and surgical timing of otogenic intracranial complications. Methods:The clinical data of 11 patients with intracranial complications with ear symptoms as the first manifestation in Department of Otorhinolaryngology Head and Neck Surgery, Qilu Hospital of Shandong University（Qingdao） from December 2014 to June 2022 were collected, including 8 males and 3 females, aged from 4 to 69 years. All patients had complete otoendoscopy, audiology, imaging and etiology examination, and the diagnosis and treatment plan was jointly developed through multidisciplinary consultation according to the critical degree of clinical symptoms and imaging changes. Among the 11 patients, 5 cases were treated with intracranial lesions first in neurosurgery department and middle ear lesions later in otolaryngology, 3 cases of meningitis, were treated with middle ear surgery after intracranial infection control, 1 case was treated with middle ear lesions and intracranial infection simultaneously, and 2 cases were treated with sigmoid sinus and transverse sinus thrombosis conservatively. They were followed up for 1-6 years. Descriptive statistical methods were used for analysis. Results:All the 11 patients had ear varying symptoms, including ear pain, pus discharge and hearing loss, etc, and then fever appeared, headache, disturbance of consciousness, facial paralysis and other intracranial complication. Otoendoscopy showed perforation of the relaxation of the tympanic membrane in 5 cases, major perforation of the tension in 3 cases, neoplasia in the ear canal in 1 case, bulging of the tympanic membrane in 1 case, and turbidity of the tympanic membrane in 1 case. There were 4 cases of conductive hearing loss, 4 cases of mixed hearing loss and 3 cases of total deafness. Imaging examination showed cholesteatoma of the middle ear complicated with temporal lobe brain abscess in 4 cases, cerebellar abscess in 2 cases, cholesteatoma of the middle ear complicated with intracranial infection in 3 cases, and sigmoid sinus thrombophlebitis in 2 cases. In the etiological examination, 2 cases of Streptococcus pneumoniae were cultured in the pus of brain abscess and cerebrospinal fluid, and 1 case was cultured in streptococcus vestibularis, Bacteroides uniformis and Proteus mirabilis respectively. During the follow-up, 1 patient died of cardiovascular disease 3 years after discharge, and the remaining 10 patients survived. There was no recurrence of intracranial and middle ear lesions. Sigmoid sinus and transverse sinus thrombosis were significantly improved. Conclusion:Brain abscess, intracranial infection and thrombophlebitis are the most common otogenic intracranial complications, and cholesteatoma of middle ear is the most common primary disease. Timely diagnosis, multidisciplinary collaboration, accurate grasp of the timing in the treatment of primary focal and complications have improved the cure rate of the disease.
