The accidents such as explosion, leakage, poisoning and fire happened constantly in dangerous goods' transportation. The consequences of the accidents are serious. This article has statistically analyzed 485 transportation accidents of dangerous goods. It shows that the main reason causing dangerous goods accidents is road traffic accidents. The key to ensure the seasonable rescue is effective visual monitor using GPS, modern communication technology, GIS to dangerous goods transport vehicles. So we construct the transportation monitoring system. When the accident inevitably occurs, we propose the rescue mission and response program. Only effective monitoring and timely rescue, can we reduce the rate of accidents and ensure our safety.
Abstract Background Growing demand for facial rejuvenation drives advancements in these therapies, including laser, radiofrequency, and focused ultrasound, alongside thermal stimulation adjuncts. These methods, known for stimulating collagen regeneration, skin tightening, and lifting, have gained popularity due to their minimal side effects, low trauma, and high safety, demonstrating favorable outcomes in clinical practice. Objective We sought to assess the efficacy of ultrasound skin tightening for brow lift within the scope of a procedure addressing facial sagging across the entire face. Our aim was to explore a noninvasive method capable of effectively enhancing mild to moderate brow ptosis by tightening and lifting the skin in the upper facial region. Methods This was a rater‐blinded, prospective cohort study. The upper facial region of the participants was treated with the new device, micro‐focused ultrasound (MFU), in model D3.0/D2.0/M3.0. Outcomes of brow lift were measured in comparison of pretreatment and posttreatment photographs and three‐dimensional (3D) vector analysis. Results A total of 42 participants (37 females) were enrolled, with 2 participants withdrawing from the trial, resulting in 40 subjects who completed 180‐day‐follow‐up and evaluation. 35 (87.5%) were deemed to have clinically significant brow elevation by two blinded assessors (experienced clinicians) at 180‐day posttreatment ( p < 0.01). The mean change in brow height after 90‐day was 2.16 ± 0.63 mm at the frontal position (straight‐ahead gaze) ( p < 0.01). The 3D vector analysis reveals varying magnitudes of vector displacement in the upward and outward directions of the skin on the frontal region above the eyebrows. Conclusion Focused ultrasound appears to be a safe and effective method for upper facial skin rejuvenation. A single focused ultrasound treatment on the forehead and temple areas resulted in an average brow elevation of 2.1 mm.
Abstract Background Endoscopic retrograde cholangiopancreatography (ERCP) has found extensive use in pediatric patients; however, challenges persist in the application of therapeutic ERCP in infants. Case presentation This case report details the presentation of a 5.9-kilogram infant with obstructive jaundice and suspected hemolytic anemia who underwent ERCP to alleviate biliary obstruction. The infant was admitted due to clay-colored stools, jaundice, and liver injury. Ultrasound and magnetic resonance cholangiopancreatography (MRCP) revealed dilation of the common bile duct (CBD) accompanied by the presence of stones. ERCP was conducted using a JF-260V duodenoscope under general anesthesia. Successful stone extraction and biliary drainage were achieved. Conclusions In centers with considerable expertise in ERCP and pediatric anesthesia, the use of a conventional adult duodenoscope for therapeutic ERCP in infants can be considered safe and feasible, provided careful and stringent patient selection criteria are applied. In the future, clear guidelines and standardized protocols for the indications and procedures of pediatric ERCP should be established.

ObjectiveCirculating tumor DNA (ctDNA) and alpha-fetoprotein (AFP) plus ultrasound (US) have been considered to have high diagnostic accuracy for cancer detection, however, the efficacy of ctDNA methylation combined with the traditional detection modality of liver cancer has not been tested in a Chinese independent cohort.MethodsThe high-risk individuals aged between 35 and 70 years who were diagnosed with liver cirrhosis or had moderate and severe fatty liver were eligible for inclusion. All participants were invited to receive a traditional examination [referring to AFP plus US], and ctDNA methylation, respectively. The sensitivity and specificity of different diagnostic tools were calculated. The logistic regression model was applied to estimate the area under the curve (AUC), which was further validated by 10-fold internal cross-validation.ResultsA total of 1,205 individuals were recruited in our study, and 39 participants were diagnosed with liver cancer. The sensitivity of AFP, US, US plus AFP, and the combination of US, AFP, and ctDNA methylation was 33.33%, 56.41%, 66.67%, and 87.18%, respectively. The corresponding specificity of AFP, US, US plus AFP, and the combination of all modalities was 98.20%, 99.31%, 97.68%, and 97.68%, respectively. The AUCs of AFP, US, US plus AFP, and the combination of AFP, US, and ctDNA methylation were 65.77%, 77.86%, 82.18%, and 92.43%, respectively. The internally validated AUCs of AFP, US, US plus AFP, and the combination of AFP, US, and ctDNA methylation were 67.57%, 83.26%, 86.54%, and 93.35%, respectively.ConclusionsThe ctDNA methylation is a good complementary to AFP and US for the detection of liver cancer.
