Objective Using cockroach surveillance data in Nanjing from 2017 to 2024, we have descriptively analyzed population characteristics and changes in insecticide resistance among Blattella germanica, and have established a seasonal Autoregressive Integrated Moving Average (ARIMA) model to predict monthly population densities in Nanjing spanning the year 2025. Methods B. germanica density and infestation rate were monitored using the sticky trap method, and insecticide resistance was assessed using the residual contact method. Our ARIMA model was applied to fit and estimate cockroach density fluctuations over time. Results From 2017 to 2024, B. germanica accounted for 94.90% of all cockroach specimens captured in Nanjing, with an average density of 0.37 cockroaches per trap and an average infestation rate of 5.56%. Significant differences in density and infestation rate were observed among different habitats (P＜0.001). Significant downward annual trends in both density and infestation rate were found (P＜0.05). ARIMA was found to be the optimal model for fitting the density data from 2017 to 2024 (0, 1, 1) × (0, 1, 1)1 2. Conclusions From 2017 to 2024, B. germanica was overwhelmingly the dominant cockroach species in Nanjing, with both its density and infestation rate declining annually. A positive correlation was observed between the amount and proportion of insecticide use and the development of insecticide resistance (P＜0.05). The established model demonstrated good performance in predicting monthly B. germanica densities in Nanjing throughout 2025, providing a valuable reference for future surveillance and control efforts.

Chronic post-dissection aortic aneurysms (PDAAs) are severe long-term complications following surgical or medical conservative management of aortic dissection, primarily caused by persistent perfusion of the residual false lumen. The persistent patency of the residual false lumen is the key pathological mechanism leading to adverse distal aortic remodeling, which can result in progressive aortic dilation, increased risk of rupture, and elevated reintervention requirements, significantly affecting patients' long-term prognosis. This article reviews the latest research progress on assessment methods, influencing factors, and intervention strategies for distal aortic remodeling in PDAAs, aiming to provide reference for clinical decision-making.

Objective:To investigate the relationship among iron content, volume and drainage venous oxygen saturation (SvO 2) in deep gray matter nuclei of healthy people using quantitative susceptibility mapping (QSM). Methods:The study was a cross-sectional study. A total of 126 healthy volunteers were prospectively enrolled in the community in Tianjin from June 2019 to December 2023, and 57 males and 69 females, aged 48±15 years. All healthy volunteers underwent MRI examinations to get STrategically Acquired Gradient Echo images, then it was post-processed to obtain T 1 weighted enhanced images, QSM maps and the maximum intensity projection images. In QSM maps, caudate nucleus (CN), putamen (PUT), globus pallidus (GP), thalamus (THU), subthalamic nucleus (STN), substantia nigra (SN) and red nucleus (RN) were semi-automatically segmented to calculate the iron content and volume using SPIN software. Four bilateral deep cerebral veins regions of interest, including septum pellucidum veins, thalamostriate veins, internal cerebral veins and basilar veins, were manually delineated on the maximum intensity projection images of QSM to obtain venous magnetic sensitivity. The venous magnetic sensitivity was calculated as SvO 2. To observe the age-related trend of SvO 2, iron content and volume, the partial correlation analysis was conducted. The relationships between iron content, volume and SvO 2 were explored using the partial correlation analysis. To explore the potential effects of SvO 2 between iron content and volume in deep gray matter, the mediation analysis was utilized. Results:The relationships between the SvO 2 of thalamostriate veins ( r=0.23, P=0.018), basilar veins ( r=0.27, P=0.004) and age were positive. The relationships between the SvO 2 of internal cerebral veins and the iron contents of CN ( r=?0.25, P=0.042) and PUT ( r=?0.33, P<0.001) were negative. The relationships between the SvO 2 of basilar veins and the iron contents of STN ( r=?0.25, P=0.042) and SN ( r=?0.24, P=0.045) were negative. The relationships between iron content and volume including CN ( r=0.46, P<0.001), PUT ( r=0.20, P=0.027), GP ( r=0.76, P<0.001), STN ( r=0.87, P<0.001), SN ( r=0.90, P<0.001), RN ( r=0.79, P<0.001) were positive. The mediation analysis showed that the SvO 2 of internal cerebral veins indirectly mediated the relationship between iron content and volume of CN, PUT, GP and THU. Conclusions:The process of iron deposition required the participation of oxygen in deep gray matter nuclei. Volume shows positive correlation with iron content in deep gray matter nuclei, with individual variations. The SvO 2 of internal cerebral veins mediate the relationship between iron content and volume of deep gray matter nuclei.

Objective:To construct an information management system based on the back-end framework of React componentization and front-end framework of Uni scalable enterprise,so as to explore its application effect in management for operation room.Methods:React was used as the backend framework to construct JavaScript program code library of user interface,and all front-end applications that adopted Uni as the development system of frontend framework were used to construct informatization management system based on React and Uni framework,so as to manage operation room of hospital.A total of 100 surgical equipment that were used in the operation room of Guizhou Provincial People's Hospital from January 2023 to December 2023 were selected.According to different management methods,the conventional management method was adopted to manage equipment during January and June 2023,while the management method of informatization management system(informatization management)based on React and Uni frameworks was adopted to manage these equipment during July and December 2023.The frequency of leaving operation room of nursing personnel due to non-nursing events,the timeliness rate of transporting surgical patients and incidence of adverse events of nursing,as well as implementation rates of"five confirmations"included confirmed equipment,confirmed staff,confirmed time,confirmed quality and confirmed quantity,between two kinds of management methods were compared.Results:In the 200 surgeries of adopting informatization management method,the frequency of leaving operation room of nursing personnel due to non-nursing events was 2.5%,which was lower than 7.5%of conventional management method,and the difference was statistically significant(x2=5.213,P<0.05).The implementation rate of the"five confirmations"for equipment was 100%,which was higher than that of conventional management methods,and the difference was statistically significant(x2=15.232,P<0.05).The timeliness rate of transporting surgical patients was 100%in 100 surgeries,which was higher than 85%of conventional management method,and the difference was significant(x2=15.136,P<0.05).The incidence of various kinds of adverse events of nursing in the operating room was 0 in 100 surgeries,which was lower than that of conventional management method,and the difference was statistically significant(x2=0.226,P<0.05).Conclusion:The informatization management system based on React and Uni framework can significantly reduce the frequency of leaving operation room of nursing personnel due to non-nursing events in operation room,and improve the work efficiency in operation room,and reduce the incidences of work errors and adverse events in management for surgery.

Objective:To investigate the short-term clinical efficacy of implantation with a 3D-printed microporous titanium prosthesis in the treatment of large segmental infectious tibial defects.Methods:A retrospective analysis was conducted of the electronic medical records of the 47 patients with large segmental tibial defects who had been treated with 3D-printed microporous titanium prostheses at Department of Orthopaedics, 920th Hospital of Joint Logistics Support Force from January 2019 to February 2024. The cohort included 36 males and 11 females, with an age of (46.2±11.8) years and a mean bone defect length of 12.3 (8.0, 16.8) cm. In the 19 patients complicated with soft tissue defects, the area of soft tissue defects ranged from 10.0 cm × 6.0 cm to 33.0 cm × 10.0 cm. For the 28 patients without soft tissue defects at the lower leg, the bone defects were filled with vancomycin-loaded calcium sulfate bone cement at the first stage; for the 19 patients complicated with soft tissue defects, the soft tissue defects at the lower limb were repaired using an anterolateral thigh flap with vascular anastomosis at the same time when bone defects were filled with vancomycin-loaded calcium sulfate bone cement at the first stage. After infection control at 2 to 8 months after surgery, individualized 3D-printed microporous titanium prostheses were implanted at the second stage to reconstruct the bone defects. Postoperative observations included the patients' first standing time, crutch walking time, full weight-bearing time, osseointegration of the tibial fracture and the prosthesis, and complications during follow-up.Results:The follow-up period for the 47 patients was (34.7±14.3) months. The first standing time was (2.2±0.6) months, crutch walking time (3.8±1.1) months, and full weight-bearing time (5.3±1.2) for this cohort. The evaluation by the Paley's bone healing score resulted in 25 excellent cases, 18 good cases, 1 medium case, and 3 poor cases, giving an excellent and good rate of 91.5% (43/47). One year after operation, the X-ray films showed that the tibial fractures and prostheses were well integrated in the 43 patients. Two patients developed recurrent tibial infection which was responded to replacement of the vancomycin-loaded calcium sulfate spacer. The fixation screws for tibial prosthesis were broken in one patient, but no recurrence of infection was observed after revision. The overall incidence of complications was 6.4% (3/47).Conclusion:In the treatment of large segmental infectious tibial defects, by facilitating rapid functional recovery and ensuring a low incidence of complications, implantation with a 3D-printed microporous titanium prosthesis demonstrates fine short-term clinical efficacy.
