Acute respiratory distress syndrome (ARDS) is the leading cause of respiratory failure with high morbidity and mortality. Pulmonary surfactant (PS)-based complementary therapies have exhibited potential for ARDS healing and applied as an adjunctive therapy strategy. Coacervate (Coac) has the characteristics of softness, deformability and excellent molecular enrichment properties, and has attracted extensive attention in the biomedical field. Here PS and coacervate were combined for the potential ARDS treatment. The Coac, fabricated from polyallylamine hydrochloride (PAH) and adenosine triphosphate (ATP) by simple mixing, exhibited soft droplet property and high enrichment for dexamethasone sodium phosphate (DSP). To avoid the fusion effect of membraneless coacervate and endow it with biological functions of PS, liposomes with PS-biomimetic lipid components (PS-lipo) were further introduced to construct PS-biomimetic membranized coacervate (DSP@PS-Coac). The DSP@PS-Coac demonstrated high lung targeting effect and significant penetration efficiency after intravenous injection. Furthermore, PS-lipo replenished the endogenous PS pool and facilitated the distribution of DSP in inflammatory cells in the lung. In the ARDS mouse model, PS-Coac and DSP exerted synergetic anti-inflammatory functions, via reducing the recruitment of inflammatory neutrophils and modulating macrophages into anti-inflammatory phenotype. The overall results confirmed that DSP@PS-Coac may provide a promising delivery option for the treatment of ARDS.

Objective:To explore the relationship between life events, anxiety, depression, and behavior problems in adolescents.Methods:From September to October 2022, the cluster sampling method was used to select 5 341 adolescents from 4 middle schools in Xinxiang urban area.The subjects and their parents were investigated by the adolescent self-rating life events check list (ASLEC), generalized anxiety disorder scale (GAD-7), patient health questionnaire (PHQ-9), and child behavior checklist (CBCL). SPSS 27.0 software was used for Spearman correlation analysis, and AMOS 28.0 software was used to construct the structural equation model.Results:The scores of anxiety, depression, and behavioral problems were 1 (0, 4), 1 (0, 4), and 3 (0, 10). The total score of life events was 5 (1, 13), and the dimensions scored as follows: interpersonal conflict 1 (0, 4), academic pressure 2 (0, 5), punishment 0 (0, 2), loss 0 (0, 0), health and adaptation problem 0 (0, 1), and others 0 (0, 2). There were positive correlations between life events and its dimensions, depression, anxiety and behavioral problems ( r=0.28-0.69, all P<0.01). In the overall population, anxiety and depression played parallel mediating roles in the impact of life events on behavior problems. Life events could positively predict anxiety ( β=0.68, P<0.01), and anxiety could positively predict behavior problems ( β=0.04, P=0.02). Life events could positively predict depression ( β=0.77, P<0.01), and depression could positively predict behavior problems ( β=0.18, P<0.01). The standardized total effect size of the impact of life events on behavioral problems was 0.622 (95% CI=0.564-0.675). The standardized direct effect size and indirect effect size were 0.460 (95% CI=0.374-0.539) and 0.162 (95% CI=0.108-0.218), accounting for 74.0% and 26.0%of the total effect, respectively. After stratification by gender, the results for male adolescents were consistent with the overall population, while the mediating effect of anxiety was not significant in the female adolescents. Conclusion:Life events can lead to anxiety and depression in adolescents, thereby increasing the risk of behavior problems.

Objective:To evaluate the clinical efficacy of the V-shaped bone tunnel technique at the base of the distal phalanx for treating tendinous mallet finger.Methods:A retrospective analysis was conducted on clinical data from patients with tendinous mallet finger treated in the Department of Hand and Foot Surgery at Linyi People’s Hospital between August 2022 and November 2023. Two oblique bone tunnels were created in a V-shaped configuration at the dorsal base of the distal phalanx, adjacent to the extensor tendon insertion, using a 0.8 mm Kirschner wire. A 4-0 double-needle monofilament tendon suture was passed through the tunnels to secure the ruptured extensor tendon to the base of the distal phalanx, followed by fixation of the distal interphalangeal (DIP) joint with a 1.0 mm Kirschner wire. The Kirschner wire was removed at 4 weeks postoperatively to initiate functional exercises. Regular follow-up was conducted to monitor wound healing and functional recovery of the DIP joint. At the final follow-up, the range of flexion and extension of the DIP joint was measured, and treatment outcomes were evaluated using Crawford’s mallet finger evaluation criteria, which classified results into four grades: excellent, good, fair, and poor.Results:Fifteen patients (16 fingers) were included, comprising 11 males and 4 females, with a mean age of 44.5 years (range: 17-65 years). The injured fingers included 2 index, 4 middle, 5 ring, and 5 little fingers, all presenting with DIP joint flexion deformity and limited active extension. Postoperative follow-up ranged from 6 to 28 months (mean: 17 months). All wounds healed primarily without complications such as infection or skin necrosis, and no cases of tendon re-rupture occurred. At the final follow-up, the measurement results of flexion and extension range of motion of the affected fingers at the DIP joint were as follows: the maximum flexion angle of all 16 fingers was 45°, among which 7 fingers had an extension angle of 0°, 8 fingers had limited extension ranging from 1° to 10°, and 1 finger had limited extension of 15°. Among the 16 fingers, 7 fingers were rated as excellent, 8 fingers as good and 1 finger as fair.Conclusion:The V-shaped bone tunnel technique for tendon-to-bone reattachment of the extensor tendon insertion is a simple and effective method for treating tendinous mallet finger. It provides satisfactory functional recovery, improves finger appearance, and is associated with minimal complications.

Objective:To explore the reliability of intraoperative fluoroscopy at lateral 10° and 30° Brodén views in addition to the standard lateral and axial calcaneal views in the lateral decubitus position to assess the quality of articular reduction in calcaneal fractures of Sanders types Ⅱ and Ⅲ.Methods:A retrospective study was conducted to analyze the clinical data of the 74 patients who had been treated at Department of Foot and Ankle Surgery, The People’s Hospital of Linyi for unilateral closed calcaneal fractures of Sanders type Ⅱ or Ⅲ from January 2024, to August 2024. According to the different methods of intraoperative fluoroscopy, the patients were divided into a precision group and a conventional group. In the precision group of 39 cases, intraoperative fluoroscopy was conducted at lateral 10° and 30° Brodén views in the surgery for calcaneal fractures in addition to the standard lateral and axial calcaneal views in the lateral decubitus position; in the conventional group of 35 cases, intraoperative fluoroscopy was conducted only in the standard lateral and axial calcaneal views in the surgery for calcaneal fractures. All patients were treated by traction assisted by external fixation, minimally invasive prying reduction through the tarsal sinus incision, and three-dimensional framework internal fixation. The 2 groups were compared in terms of frequency of intraoperative fluoroscopy; preoperative and postoperative B?hler angles, Gissane angles, and calcaneal varus angles; screw protrusions (more than 2 mm beyond the medial cortex) of the posterior articular surface screw, sustentaculum tali screw, and anterior tuberosity screw; skin irritation symptoms due to the main nail tail (protruding cortex > 1 mm); step-off of the posterior articular surface (more than 2 mm) and wide gap of the posterior articular surface (more than 2 mm).Results:There were no statistically significant differences in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). Both groups showed significant postoperative improvements in X-ray B?hler angle, Gissane angle, and calcaneal varus angle compared with the preoperative values ( P<0.05). There were no statistically significant differences in postoperative X-ray B?hler angle, Gissane angle, or calcaneal varus angle between the 2 groups ( P>0.05). There was no statistically significant difference in the frequency of intraoperative fluoroscopy between the 2 groups either ( P>0.05). The precision group had significantly fewer cases of screw protrusion (more than 2 mm beyond the medial cortex) of the posterior articular surface screw, sustentaculum tali screw, and anterior tuberosity screw, skin irritation symptoms due to the main screw tail (protruding cortex>1 mm), step-off of the posterior articular surface (more than 2 mm), and wide gap of the posterior articular surface (more than 2 mm) on the postoperative CT three-dimensional reconstruction compared with the conventional group ( P<0.05). Conclusion:In surgery for calcaneal fractures of Sanders types Ⅱ and Ⅲ, intraoperative fluoroscopy at lateral 10° and 30° Brodén views in addition to the standard lateral and axial calcaneal views in the lateral decubitus position provides stable and reliable intraoperative monitoring of B?hler angle, Gissane angle, calcaneal varus angle, reduction of the posterior articular surface of the calcaneus and the positions and lengths of implants.

OBJECTIVES: Primary trigeminal neuralgia (PTN) is a common cranial nerve disease in neurosurgery, which seriously endangers the physical and mental health of patients. Percutaneous balloon compression (PBC) has become an effective procedure for the treatment of PTN by blocking pain conduction through minimally invasive puncture. However, the recurrence of facial pain after PBC is still a major problem for PTN patients. Intraoperative balloon shape, pressure and compression time can affect the prognosis of patients with PBC after surgery. The foramen ovale size has an effect on the balloon pressure in Meckel's lumen. This study aims to analyse the predictive value of foramen ovale size for postoperative pain recurrence of PBC by exploring the relationship between foramen ovale size and postoperative pain recurrence of PBC. METHODS: A retrospectively analysis was conducted on the clinical data of 60 patients with PTN who were treated with PBC in Department of Neurosurgery, Affiliated Hospital of Chengde Medical College from November 2018 to December 2021. We followed-up and recorded the Barrow Neurological Institute (BNI) pain score at 1, 3, 6 and 12 months after operation. According to the BNI pain score at 12 months after surgery, the patients were divided into a cure group (BNI pain score I to Ⅱ) and a recurrence group (BNI pain score Ⅲ to Ⅴ). The long diameter, transverse diameter and area of foramen ovale on the affected side and the healthy side of the 2 groups were measured. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used for analysis the relationship between the recurrence of pain and the long diameter, transverse diameter, area of foramen ovale on the affected side, and aspect ratio, transverse diameter ratio, area ratio of foramen ovale on the affected side to healthy side in the 2 groups. RESULTS: At the end of 12 months of follow-up, 50 (83.3%) patients had pain relief (the cured group), 10 (16.7%) patients had different degrees of pain recurrence (the recurrence group), and the total effective rate was 83.3%. There were no significant differences in preoperative baseline data between the 2 groups (all P>0.05). The long diameter of foramen ovale on the affected side, the long diameter ratio and area ratio of foramen ovale on the affected/healthy side in the cured group were significantly higher than those in the recurrence group (all P<0.05), and there were no significant differences in the transverse diameter and area of foramen ovale on the affected side and the transverse diameter ratio of foramen ovale on the affected/healthy side between the 2 groups (all P>0.05). The ROC curve analysis showed that the AUC of the long diameter of foramen ovale on the affected side was 0.290 (95% CI 0.131 to 0.449, P=0.073), and the AUC of aspect ratio of foramen ovale on the affected side to healthy side was 0.792 (95% CI 0.628 to 0.956, P=0.004). The AUC of area ratio of foramen ovale on the affected side to healthy side was 0.766 (95% CI 0.591 to 0.941, P=0.008), indicating that aspect ratio and area ratio of foramen ovale on the affected side to healthy side had a good predictive effect on postoperative pain recurrence of PBC. When aspect ratio of foramen ovale on the affected side to healthy side was less than 0.886 3 or area ratio of foramen ovale on the affected side to healthy side was less than 0.869 4, postoperative pain recurrence was common. CONCLUSIONS Accurate evaluation of the foramen ovale size of skull base before operation is of great significance in predicting pain recurrence after PBC.
