Severe acute pancreatitis (SAP) can induce acute respiratory distress syndrome (ARDS) and abdominal compartment syndrome (ACS). Although prone position ventilation (PPV) can improve outcomes in patients with ARDS, there is significant controversy regarding its concurrent use with ACS owing to concerns of increased risk of intra-abdominal pressure (IAP).[1] We present a case of successful PPV application without adverse effects.

Objective To analyze the application effect of anterolateral femoral free flap transplantation based on three-dimensional reconstruction in CT angiography in the treatment of chronic osteomyelitis of the foot and ankle complicated with soft tissues defect.Methods A retrospective analysis was conducted on the clinical data of 105 patients with chronic osteomyelitis of the foot and ankle complicated with soft tissues defect who were admitted to Suining Central Hospital in Sichuan Province from January 2020 to January 2023.Patients enrolled were divided into the control group(n=52)and the observation group(n=53)according to different perforating blood vessel examination methods before surgery.The control group underwent anterolateral femoral free flap transplantation based on handheld Doppler ultrasound,while the observation group underwent anterolateral femoral free flap transplantation based on CTA three-dimensional reconstruction technology.Comparison between the groups was made on inflammatory factors(CRP,TNF-α and IL-6),skin flap repair effect,foot and ankle function(AOFAS)score,flap sensation,survival rate of skin flaps,and the incidence of adverse events.Results On day 14 after operation,serum CRP,TNF-α and IL-6 levels in the observation group were lower than those in the control group(P＜0.05).Six months after operation,the effect of flap repair in observation group was better than that in control group,and the survival rate of flap was higher than that in control group(100.00％vs 92.31％)(P＜0.05).Twelve months after operation,AOFAS score and flap sensation score of the observation group were higher(P＜0.05).The incidence of adverse events was lower in the observation group than in the control group(3.77％ vs.15.38％)(P＜0.05).Conclusion Anterolateral femoral free flap transplantation based on CTA 3D reconstruction technique can repair soft tissue defect and reduce the risk of adverse events while can cure chronic osteomyelitis.

Objective Hypobaric chamber and simulated weightless bed are essential methods for aerospace medical research,and conducting state assessment of volunteers before and after hypobaric chamber and simulated weightless bed tests is an essential guideline for aerospace implementation medicine.To further improve the efficiency of human condition assessment,in addition to the conventional biochemical and physiological indicators,the human oral exhaled gas can be used for condition assessment,and the olfactometry acquisition equipment and analysis software can collect and detect most volatile gases to complete the human oral exhaled gas data acquisition.Conducting comparative analysis of olfactory mapping data from different populations may be a means to assess the status of the body.Methods The olfactometry acquisition equipment was used to collect the oral exhaled breath olfactometry profiles of the general population,hypobaric cabin volunteers,and ambulatory volunteers.The olfactometry analysis software was used to calculate the 12 eigenvalues of the olfactometry profiles and the t-SNE downscaling,and the radar plots were used to analyze the olfactometry profiles of the general population,low-pressure cabin volunteers,and ambulatory volunteers respectively.A comparative analysis of different populations was conducted.Results(1)The t-SNE mapping data of the general population and the ambulatory volunteers were almost indistinguishable;(2)the t-SNE mapping data of the hypobaric cabin volunteers and the general population had a slight overlap,but the distinguishability of the vast majority of the t-SNE mapping data was obvious;(3)the t-SNE mapping data of the hypobaric cabin volunteers and the ambulatory volunteers were distinguishable with no overlap,and the ambulatory t SNE data are highly aggregated,and the distribution of t-SNE data in low-pressure cabin is more discrete;(4)there are 2-3 sensors with large eigenvalues and a large range of variation for both low-pressure cabin volunteers and recumbent volunteers after training activities,and the common sensor with a large range of variation is S6.Conclusion Olfactory diagnostic analysis mapping may be a means to assess the health status of the body and may be useful for spaceflight health status assessment in the future.The analysis and application of flight health state assessment can be a reference in the future.

Occlusal plane (OP) is one of the essential factors affecting craniofacial morphology and function. The OP not only assists in diagnosing malocclusion but also serves as an important reference for making treatment plans. Patients with different types of malocclusions have different forms of OP. Compared with patients with standard skeletal facial type, the occlusal plane of patients with skeletal class Ⅱ and high angle is steeper, while that of patients with skeletal class Ⅲ and low angle is more even. In orthodontic treatment, adjusting and controlling the OP can promote the normal growth and development of the mandible in most patients with malocclusion during the early stage of growth, while causing favorable rotation of the mandible in some adults with mild-to-moderate malocclusion. For moderate-to-severe malocclusion, the OP rotation by orthodontic-orthognathic treatment can achieve better long-term stability. This article reviews the evolution of the definition of OP and its implications for diagnosing and the guiding treatment of malocclusion.
