A 42-year-old male with chest tightness and dyspnea was admitted to the hospital. Chest CT indicated diffuse interstitial lung infiltration. Despite receiving anti-infective therapy, glucocorticoid therapy, and immunosuppressive agents, the patient developed refractory hypoxaemia. Endotracheal intubation and invasive mechanical ventilation failed to improve oxygenation. Therefore the patient was diagnosed with rapidly progressive interstitial lung disease (RP-ILD) accompanied by type Ⅰ respiratory failure. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) was initiated, and oxygenation improved in this patient. The patient subsequently underwent bilateral lung transplantation with veno-arterio-venous (VAV) ECMO support. ECMO machine was withdrawn on day 1, and extubation was achieved on day 9 after surgery. Histopathology revealed fibrotic nonspecific interstitial pneumonia (NSIP) with hyaline membrane formation. The patient developed ICU-acquired myasthenia and received early rehabilitation, with gradual recovery of muscle strength. During follow-up, graft lung function remained stable. This case demonstrates that ECMO can serve as a bridge to lung transplantation in RP-ILD patients.

ObjectiveTo compare the mosquito capture efficacy of the BG-trap method and the light trap method, and to explore the precisely applicable scenarios for the two monitoring approaches. MethodsFrom May to October 2024, one BG-trap and one light trap were placed at eight monitoring sites, with a distance of over 10 meters between the two traps at each site. Surveillance was performed twice monthly to compare the two surveillance methods in terms of mosquito species composition, the proportional distribution of female mosquitoes across different habitats, and seasonal fluctuations in mosquito density. ResultsThere were statistically significant differences in mosquito species composition (χ²=60.61, P<0.001) and female mosquito species composition (χ²=37.12, P<0.001) between the BG-trap method and the light trap method, with the BG-trap method capturing a higher proportion of Aedes albopictus than the light trap method. The average density of mosquitoes monitored by the BG-trap method [13.36 mosquitoes·(trap·night)^-1] was higher than that monitored by the light trap method[4.70 mosquitoes·(trap·night)^-1]. There was statistically significant difference (t=6.70, P<0.001) for the mosquito density between the two methods, and there was a significant positive correlation (r=0.909, P<0.001) for the mosquito density indices between the two methods. The average density of female mosquitoes monitored by the BG-trap method [8.18 mosquitoes·(trap·night)^-1] was higher than that monitored by light trap method [3.36 mosquitoes·(trap·night)^-1]. There was statistically significant difference (t=6.00, P<0.001) for the female mosquito density between the two methods, and there was a significant positive correlation (r=0.929, P<0.001) for the female mosquito density indices between the two methods. In the four different habitats, the constituent ratio of mosquitoes and female mosquitoes monitored by the BG-trap method in descending order were urban residential area (43.80% and 40.25%), rural farm households (35.55% and 38.60%), hospital (12.70% and 12.87%), and park (7.95% and 8.28%), while the constituent ratio of mosquitoes and female mosquitoes monitored by the light trap method in descending order were rural farm households (34.37% and 43.34%), hospital (33.26% and 30.03%), park (17.96% and 15.17%), and urban residential area (14.41% and 11.46%). In different habitats, there were statistically significant differences for mosquito composition ratios (χ²=189.64, P<0.001) and female mosquito composition ratios (χ²=109.15, P<0.001) between the two monitoring methods. ConclusionThe BG-trap method offers advantages such as simple operation, compact equipment, and high efficiency, with a higher trapping rate for Aedes albopictus compared to the light trap method. In routine monitoring, the BG-trap method can serve as a supplement to the light trap method, while for emergency monitoring of Aedes albopictus in dengue fever outbreak areas and mosquito collection efforts, the BG-trap method is more effective than the light trap method.

Objective To investigate the changes in the density of Aedes albopictus across different regions and different breeding habitats in Baoshan District, Shanghai Municipality from 2018 to 2024, so as to inform evidence-based control strategies for mosquito-borne infectious diseases in Shanghai Municipality. Methods Ae. albopictus surveillance sites were deployed in 12 subdistricts (towns) of Baoshan District, Shanghai Municipality from 2018 to 2024, and the surveillance on the density of Ae. albopictus was performed in each surveillance site once weekly during the peak activity period of Aedes mosquitoes from May to October each year from 2018 to 2024. Mosquito ovitraps were deployed in various breeding habitats in each surveillance site according to geographical locations, including residential areas, schools, government institutions, hospitals, recycling stations, and construction sites, and regularly collected, and the mosquito ovitrap index (MOI) was calculated. The changes in the Ae. albopictus density were analyzed based on MOI across years, regions, and breeding habitats. Additionally, from May to October each year between 2018 and 2024, monthly risk assessments of Aedes albopictus density were conducted in every subdistrict (town) of Baoshan District, Shanghai. Results The annual mean MOI values of Ae. albopictus were 5.88 ± 2.29, 8.19 ± 4.46, 7.43 ± 3.40, 5.44 ± 2.52, 3.97 ± 2.72, 3.82 ± 1.57, and 2.56 ± 1.11 in Baoshan District from 2018 to 2024, respectively (F = 75.886, P < 0.05), and the MOI appeared a rise followed by a reduction each year and peaked during the period between June and August. There was a significant difference in the 7-year mean MOI of Ae. albopictus across the 12 subdistricts/towns (F = 26.558, P < 0.05), and there were 6 subdistricts/towns with a 7-year mean MOI of over 5, including Songnan Town (8.44 ± 4.68), Dachang Town (7.71 ± 5.28), Gucun Town (7.13 ± 3.57), Yuepu Town (5.74 ± 1.69), Gaojing Town (5.51 ± 3.44), and Wusong Subdistrict (5.41 ± 2.04). There was a significant difference in the MOI of Ae. albopictus across breeding habitats (F = 3.843, P < 0.05), with the highest MOI seen in recycling stations (9.86 ± 4.61), which was significantly higher than in other habitats (P < 0.05), and the lowest seen in construction sites (4.90 ± 2.95), which was significantly lower than in other habitats (P < 0.05). The proportion of frequency with Ae. albopictus density transmission risk decreased from 54.17% in 2018 to 11.11% in 2024 in all subdistricts (towns) of Baoshan District, and the frequency of outbreak risks peaked in 2019 (18 instances) and declined substantially in 2021 (6 instances), with no records of outbreak or transmission risk documented across the district in 2024. Conclusions There were substantial seasonal variations in the Ae. albopictus density in Baoshan District, Shanghai Municipality from 2018 to 2024. The Ae. albopictus density peaked during the period between June and August in Baoshan District each year from 2018 to 2024, with a relatively higher density in Songnan Town and Dachang Town, and in recycling stations. Precision control measures and intensified seasonal interventions are recommended in high-risk settings in Baoshan District to reduce the transmission risk of Aedes-borne infectious diseases.

China emerges as a major country in nuclear energy development and the application of nuclear and radiologic technology. The diagnosis and treatment of acute radiation syndrom (ARS) caused by external irradiation represent a core function in the country′s medical rescue of nuclear and radiological emergencies. Clinically, ARS manifests hematopoietic, gastrointestinal, cutaneous, and central nervous system syndromes, with specific clinical manifestations, signs, severity, and prognosis strongly correlated with radiation dose. China has established a number of national and provincial centers for treating radiation-induced damage. Nevertheless, most medical staff have limited experience in ARS treatment. This consensus presents a summary of recent experience in treating ARS of China. In combination with recommendations from international organizations such as the World Health Organization (WHO), this consensus proposes key evidence of critical clinical issues of ARS, covering all links in the rescue of external irradiation-induced ARS. Initially, clinical diagnosis, syndromes, and severe degrees should be determined based on clinical symptoms and dose estimates. It is necessary to normalize clinical treatment measures for hematopoietic recovery, gastrointestinal injury treatment, infection control, symptomatic treatment, and multi-organ function preservation. To this end, this consensus offers cautions. This consensus provides principles of treatment with traditional Chinese medicine, psychological intervention, and follow-up. Additionally, it highlights multidisciplinary collaboration. It is recommended that this consensus be applied in relevant treatment centers.

Objective:To investigate the clinical efficacy of lumbar lateral interbody fusion (LLIF) versus posterior lumbar interbody fusion (PLIF) in the treatment of severe lumbar spinal stenosis.Methods:The data of patients with severe lumbar spinal stenosis who underwent LLIF or PLIF from February 2019 to December 2023 were retrospectively analyzed. There were 30 patients in the LLIF group, 10 males and 20 females, aged 62.7±5.6 years (range, 53-74 years), including 21 cases of single segment and 9 cases of double segment. There were 46 patients in the PLIF group, including 20 males and 26 females, aged 63.2±8.4 years (range, 43-75 years), 40 cases of single segment and 6 cases of double segment. The visual analogue scale (VAS), Oswestry disability index (ODI), intervertebral space height, intervertebral foramen height and postoperative complications were compared between the two groups.Results:All patients were followed up for an average of 21.3±6.4 months (range, 12-32 months). The intraoperative blood loss in the LLIF group was 112.2±76.9 ml, which was significantly lower than 193.9±88.2 ml in the PLIF group ( P<0.05). The VAS scores of back pain and leg pain after operation were significantly lower than those before operation in the two groups ( P<0.05). There was no statistically significant difference between groups in back pain VAS scores at preoperative, 6 months postoperative, and final follow-up ( P>0.05); the back pain VAS score at 1 month postoperatively in the LLIF group was 1.6±1.2, which was less than 2.8±0.7 in the PLIF group ( P<0.05). There was no statistically significant difference between groups in leg pain VAS scores at preoperative, 1 month postoperative, and 6 months postoperative ( P>0.05); the leg pain VAS score at the final follow-up in the LLIF group was 1.2±1.5, which was smaller than 1.8±1.0 in the PLIF group ( P<0.05). The postoperative ODI was smaller than the preoperative one in both groups, and the difference was statistically significant ( P<0.05); the preoperative, 1-month postoperative, 6-month postoperative, and final follow-up ODIs in the LLIF group were 45.7%±16.0%, 17.9%±12.0%, 16.2%±11.6%, and 15.7%±11.7%, and those in the PLIF group were 47.9%±15.4%, 20.1%±9.3%, 16.9%±10.6%, and 14.6%±11.0% in the PLIF group, and the difference between the groups was not statistically significant ( P>0.05). The preoperative intervertebral space height in the LLIF group was 10.6±2.0 mm, which was smaller than that in the PLIF group 11.8±2.2 mm ( P<0.05). The intervertebral space heights in the immediate postoperative period and at the final follow-up were 13.3±2.3 mm and 12.3±2.2 mm in the LLIF group and 13.7±1.7 mm and 13.0±1.9 mm in the PLIF group ( P>0.05). The preoperative intervertebral foraminal height in the LLIF group was 18.0±3.2 mm, which was smaller than that of 19.7±2.4 mm in the PLIF group ( P<0.05); the intervertebral foraminal heights in the immediate postoperative period and at the final follow-up were 21.4±2.5 mm and 20.2±2.4 mm in the LLIF group, and in the PLIF group were 20.7±2.4 mm and 19.7±2.6 mm in the PLIF group ( P>0.05). In the LLIF group, 2 cases had femoral nerve injury and 2 cases had transient back pain after operation. There were 2 cases of cerebrospinal fluid leakage, 1 case of screw loosening, and 2 cases of deep vein thrombosis in the PLIF group. In the PLIF group, 2 patients underwent revision, including 1 case due to cage displacement and 1 case due to screw malposition. The fusion settling rate was 21% (8/39) in the LLIF group and 12% (6/52) in the PLIF group ( P>0.05). Conclusion:Both LLIF and PLIF can effectively restore the intervertebral height, improve the lumbar function and the symptoms of back and leg pain in the treatment of severe lumbar spinal stenosis.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

ObjectiveTo evaluate the field mosquito surveillance efficacy between the black box method and the light trap method. MethodsEight light traps and eight black boxes were placed in each of the eight field sites in Baoshan District of Shanghai， with a minimum distance of 10 meters between each traps. Surveillance was conducted twice a month from May to September 2023. ResultsThe total number of mosquitoes （273） and female mosquitoes （228） captured by the black box method were 0.795 and 0.774 times higher than those caught by the light trap method， respectively. There was no statistically significant difference （P>0.05） between the mosquito density （t=1.723 5， P=0.100 2） and the female mosquito density （t=1.805 9， P=0.101 1）， and there was a correlation （P<0.001） between the mosquito density （r=0.942 7） and the female mosquito density （r=0.896 5）. There were no significant differences in the composition ratio of mosquito species（χ²=0.100 1， P>0.05） and female mosquitoes（χ²=0.394 4， P>0.05） captured by black box and light trap methods. In four different habitats， the composition ratios of mosquito species captured by the black box and light trap methods were： hospitals （38.10% and 38.77%） > rural housing areas （36.26% and 37.61%） > parks （14.65% and 12.54%）> urban housing areas （10.99% and 11.08%）， and the composition ratios of female mosquitoes captured by the black box and light trap methods were： rural housing areas （40.35% and 42.52%） > hospitals （37.72% and 36.05%） > parks （13.16% and 13.27%） > urban housing areas （8.77% and 8.16%）. In different habitats， there was no significant difference in the composition ratio of mosquitoes captured by two monitoring methods（χ²=0.5987， P>0.05）， and there was no significant difference in the composition ratio of female mosquitoes（χ²=0.2993， P>0.05）. ConclusionWith widen application and fewer requirements for equipment， operation skills， and use cost the black box method can be interchanged with the light trap method for monitoring mosquito density， especially in disaster areas or remote areas with difficult in having access to electricity.
