OBJECTIVE: To identify early potential risk factors for hospital-acquired pneumonia (HAP) in patients with mild traumatic brain injury (mTBI), construct a risk prediction model, and evaluate its predictive efficacy. METHODS: A case-control study was conducted using clinical data from mTBI patients admitted to the neurosurgery department of Changzhou Second People's Hospital from September 2021 to September 2023. The patients were divided into two groups based on whether they developed HAP. Clinical data within 48 hours of admission were statistically analyzed to identify factors influencing HAP occurrence through univariate analysis. Least absolute shrinkage and selection operator (LASSO) regression analysis was employed for feature selection to identify the most influential variables. The dataset was divided into training and validation sets in a 7:3 ratio. A multivariate Logistic regression analysis was then performed using the training set to construct the prediction model, exploring the risk factors for HAP in mTBI patients and conducting internal validation in the validation set. Receiver operator characteristic curve (ROC curve), decision curve analysis (DCA), and calibration curve were utilized to assess the sensitivity, specificity, decision value, and predictive accuracy of the prediction model. RESULTS: A total of 677 mTBI patients were included, with 257 in the HAP group and 420 in the non-HAP group. The significant differences were found between the two groups in terms of age, maximum body temperature (MaxT), maximum heart rate (MaxHR), maximum systolic blood pressure (MaxSBP), minimum systolic blood pressure (MinSBP), maximum respiratory rate (MaxRR), cause of injury, and laboratory indicators [C-reactive protein (CRP), procalcitonin (PCT), neutrophil count (NEUT), erythrocyte sedimentation rate (ESR), fibrinogen (FBG), fibrinogen equivalent units (FEU), prothrombin time (PT), activated partial thromboplastin time (APTT), total cholesterol (TC), lactate dehydrogenase (LDH), prealbumin (PAB), albumin (Alb), blood urea nitrogen (BUN), serum creatinine (SCr), hematocrit (HCT), hemoglobin (Hb), platelet count (PLT), glucose (Glu), K⁺, Na⁺], suggesting they could be potential risk factors for HAP in mTBI patients. After LASSO regression analysis, the key risk factors were enrolled in the multivariate Logistic regression analysis. The results revealed that the cause of injury being a traffic accident [odds ratio (OR) = 2.199, 95% confidence interval (95%CI) was 1.124-4.398, P = 0.023], NEUT (OR = 1.330, 95%CI was 1.214-1.469, P < 0.001), ESR (OR = 1.053, 95%CI was 1.019-1.090, P = 0.003), FBG (OR = 0.272, 95%CI was 0.158-0.445, P < 0.001), PT (OR = 0.253, 95%CI was 0.144-0.422, P < 0.001), APTT (OR = 0.689, 95%CI was 0.578-0.811, P < 0.001), Alb (OR = 0.734, 95%CI was 0.654-0.815, P < 0.001), BUN (OR = 0.720, 95%CI was 0.547-0.934, P = 0.016), and Na⁺ (OR = 0.756, 95%CI was 0.670-0.843, P < 0.001) could serve as main risk factors for constructing the prediction model. Calibration curves demonstrated good calibration of the prediction model in both training and validation sets with no evident over fitting. ROC curve analysis showed that the area under the ROC curve (AUC) of the prediction model in the training set was 0.943 (95%CI was 0.921-0.965, P < 0.001), with a sensitivity of 83.6% and a specificity of 91.5%. In the validation set, the AUC was 0.917 (95%CI was 0.878-0.957, P < 0.001), with a sensitivity of 90.1% and a specificity of 85.0%. DCA indicated that the prediction model had a high net benefit, suggesting practical clinical applicability. CONCLUSIONS The cause of injury being a traffic accident, NEUT, ESR, FBG, PT, APTT, Alb, BUN, and Na⁺ are identified as major risk factors influencing the occurrence of HAP in mTBI patients. The prediction model constructed using these parameters effectively assesses the likelihood of HAP in mTBI patients.

Objective: To investigate the impact of tumor necrosis factor ligand superfamily member 13(TNFSF13) derived from M2 macrophages on temozolomide(TMZ) resistanceviaregulating interferon regulatory factor 8(IRF8) in glioblastoma(GBM) cells. Methods: Immunohistochemistry(IHC) was used to detect the expression of TNFSF13 in normal brain tissues and GBM tissues. ELISA was used to measure the expression of TNFSF13 in the conditioned media(CM) of M0-type macrophages and M2-type macrophages. M0-CM and M2-CM were used to culture U251 sensitive(U251/S) and resistant(U251/R) cells. The TMZ treatment group was also treated with 800 μmol/L TMZ. The U251/R cells were divided into the following groups: con group, M2vector-CM group, M2vector-CM+TMZ group, M2TNFSF13-CM group, M2TNFSF13-CM+TMZ group, si-IRF8 group, and si-IRF8+M2TNFSF13-CM group. CCK-8 assay was used to detect cell viability and calculate the IC50value. Transwell assay was used to detect cell invasion. Flow cytometry was used to detect apoptosis. Western blot was used to detect the expression of IRF8. Nude mouse xenograft models were constructed and the nude mice were divided into the following groups: U251+M2si-NCgroup, U251+M2si-TNFSF13group, U251+M2si-NC+TMZ group, U251+M2si-TNFSF13+TMZ group. The tumor volume and mass of each group were measured, and IHC was used to detect the expression of TNFSF13 and CD206 in tumor tissues of each group. Results: Compared with adjacent tissues and M0-CM, the expression of TNFSF13 was up-regulated in cancer tissues and M2-CM. Compared with the M0-CM group, the IC50value of TMZ and the number of cell invasions in U251/S and U251/R cells in the M2-CM group significantly increased(allP<0.05). Overexpression of TNFSF13 in M2 macrophages could promote the IC50value of TMZ in U251/R cells, promote cell invasion, and inhibit cell apoptosis(allP<0.05). Overexpression of TNFSF13 promoted the expression of IRF8, and knocking down IRF8 could attenuate the TMZ resistance of U251/R mediated by overexpression of TNFSF13.In vivostudies showed that knocking down TNFSF13 alone or combined with TMZ treatment significantly inhibited tumor growth and reduced the expression of TNFSF13 and CD206. Conclusion TNFSF13 derived from M2 macrophages promotes TMZ resistance in GBM cells by activating IRF8.

Objective:To investigate the necessity of internal fixation of the fibular fracture in the treatment of degree Ⅱ ankle supination-external rotation injury by the Dias-Tachdjian classification in children.Methods:A retrospective study was conducted to analyze the data of 69 children with ankle fracture (degree Ⅱ ankle supination-external rotation injury by the Dias-Tachdjian classification) who had been treated at Department of Orthopedic Trauma, The People's Hospital of Weifang and Department of Pediatric Orthopedics, Tianjin Hospital from January 2015 to October 2021. There were 41 males and 28 females with an age of (10.1±1.4) years, and 37 left and 32 right sides affected. The patients were divided into 2 groups according to whether internal fixation of the fibular fracture was performed. Group A consisted of 21 cases with fibular internal fixation and group B of 48 cases without fibular internal fixation. The preoperative data, operation time and operation expenses were recorded and compared between the 2 groups. At the last follow-up, the anteroposterior and lateral radiographs of bilateral full length lower limbs and ankle joints were taken; the lateral distal tibial angle (LDTA) and the anterior distal tibial angle (ADTA) on the affected side, and the disparity between bilateral ankle tibiotalar angles were measured; ankle function was assessed according to the ankle-hindfoot score of American Association of Foot and Ankle Surgery (AOFAS); the occurrence of premature physeal closure (PPC) was recorded.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (19.5±4.1) months. At the last follow-up, the LDTA on the affected side was 89.6° (87.9°, 90.5°) in group A and 88.6°±1.9° in group B; the ADTA on the affected side was 80.9° (79.0°, 81.4°) in group A and 80.0° (78.6°, 81.2°) in group B; the disparity between bilateral ankle tibiotalar angles was 1.1°±0.5° in group A and 1.2°±0.5° in group B; the AOFAS ankle-hindfoot score was (89.5±5.2) points in group A and 89.0 (87.0, 92.0) points in group B. There was no statistically significant difference between the 2 groups in the above items ( P>0.05). The incidence of PPC was, respectively, 14.3% (3/21) and 14.6% (7/48) in groups A and B, showing no statistically significant difference ( P>0.05). Conclusions:In the treatment of degree Ⅱ ankle supination-external rotation injury in children, internal fixation of the fibular fracture has no significant effect on the imaging angles or the function of the ankle joint. After anatomic reduction of the distal tibia, the fibular fracture can be treated without internal fixation to reduce operational trauma, shorten operation time and reduce operation expenses.

Objective:To investigate the efficacy of staged treatment of infectious femoral defects of Cierny-Mader type Ⅳ using bone transport combined with locking plating after En-Bloc resection debridement.Methods:A retrospective analysis was conducted of the 10 patients with distal femoral traumatic bone infection who had been treated at Department of Orthopedics, The People's Hospital of Weifang from January 2020 to January 2023. There were 8 males and 2 females with an age of (48.5±11.4) years. All cases were classified as Cierny-Mader type Ⅳ. At the first stage, En-Bloc resection debridement was performed in all cases to remove previous internal fixation devices and fill the defects with antibiotic bone cement. After infection control, the second stage involved removal of bone cement, re-fixation with internal devices, and external fixation support for bone transport. After the bone segments met, freshening of the bone ends, minor bone grafting, and screw locking of the transported bone segments were performed. Outcomes observed included bone defect length, frame carrying time and index, bone healing time, limb function, and complications.Results:After the first stage of debridement, a bone defect of (9.1±2.1) cm was created in 10 patients. All patients were followed up for (19.8±6.6) months. The duration for carrying external fixation frame was (107.2±25.1) days, and the frame index (11.8±0.5) d/cm. No recurrence was observed postoperatively. Bone union was achieved in 9 patients within 8 months, but in 1 patient only after secondary bone grafting due to poor healing at the meeting ends. All patients returned to their previous life or physical labor with no complications like pain or re-fracture. Three patients experienced varying degrees of knee joint stiffness, but were able to meet needs of daily life; one requested joint release surgery which resulted in satisfactory therapeutic efficacy.Conclusion:Staged treatment of infectious femoral defects of Cierny-Mader type Ⅳ using bone transport combined with locking plating after En-Bloc resection debridement is simple and effective.

Objective To study the impact of a Western diet-type feed on biological indicators and histopathology in APOE-/-mice.Methods Forty-eight female and 48 male APOE--mice,and 48 female and 48 male C57BL/6J mice were divided into eight breeding groups:APOE-/-breeding feed group,APOE-/-Western dietary feed group,C57BL/6J breeding feed group,and C57BL/6J Western dietary feed group(24 male and 24 female mice per group).Mice were fed the respective diets from 3 weeks until the end of the experiment at 20 weeks.After the experiment,serum was collected for measurement of biochemical indicators.Aortas were removed for oil red O staining and gross examination and the aorta root was paraffin sectioned and stained with hematoxylin and eosin.Results A Western diet did not significantly increase body weight in APOE-/-mice,but did significantly improve the blood lipid index and total cholesterol,low-density lipoprotein,and high-density lipoprotein levels,and promoted the formation of atherosclerotic plaques.Male mice were suitable for modeling gross aortic plaques while female mice were suitable for modeling aortic arch root plaques.Conclusions A Western diet can promote atherosclerosis in APOE-/-mice,increase the aortic plaque area ratio,shorten modeling time,and improve modeling uniformity.

Objective:To identify early potential risk factors for sepsis-associated liver injury and to provide a reference for early clinical identification and intervention.Methods:The clinical data of septic patients admitted to the intensive care unit (ICU) in the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University from March 2020 to April 2023 were retrospectively analyzed. Patients with sepsis were categorized into the liver injury group and the non-liver injury group according to whether liver injury occurred or not, univariate and multivariate logistic regression analyses were used to explore the risk factors for SALI, receiver operating characteristic (ROC) curve analysis was used to assess its predictive effect for SALI, and performed subgroup analyses basing on the cut-off point.Results:Among 530 eligible patients, 403 patients were included. The incidence of liver injury was 39.45% in 159 cases with liver injury and 244 cases without liver injury. Multivariate logistic regression analysis showed that serum prealbumin, lactate and lactate dehydrogenase were independent risk factors for SALI. ROC curve analysis showed that all single indicators had some predictive value for SALI, the area under the curve was prealbumin (AUC: 0.752, 95% CI: 0.703-0.801), lactate (AUC: 0.679, 95% CI: 0.627-0.732), lactate dehydrogenase (AUC: 0.664, 95% CI: 0.611-0.718), respectively, The AUC for predicting SALI by lactate/prealbumin ratio (L/P) and lactate dehydrogenase/prealbumin ratio were 0.808 (95% CI: 0.766-0.850) and 0.795 (95% CI: 0.750-0.840), respectively, with the best efficacy of L/P in predicting SALI. Subgroup analyses showed that the incidence of liver injury was significantly higher in septic patients with L/P ≥0.23 than that in septic patients with L/P <0.23, at the same time, the acute physiology and chronic health evaluation II score, shock probability, and hospital mortality rate also increased accordingly, the differences were all statistically significant (all P < 0.001). Conclusions:L/P is early independent risk factor of SALI, for sepsis patients with L/P≥0.23 should be alerted to the development of liver injuryis.
