ObjectiveTo study the effect of Taikong Yangxin Pills on the metabolism of simulated weightless rats based on metabolomics and discuss the metabolism mechanism. MethodsIn the simulated space capsule environment on the ground， the rat model of simulated weightlessness was established by the tail suspension method. Rats were randomly grouped as follows： out-of-capsule control， in-capsule control， model， and high （3.0 g·kg^-1） and low （1.5 g·kg^-1） doses of Taikong Yangxin Pills， and they were administrated with corresponding drugs by gavage for 28 days. The serum levels of endogenous metabolites in rats were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF/MS）. The obtained data were processed by principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） to screen for differential metabolites and potential biomarkers. MetaboAnalyst 5.0 was used for pathway enrichment analysis to explain the metabolic regulation mechanism of the drug. ResultsCompared with the out-of-capsule control group， the in-capsule control group showed elevated levels of thirteen metabolites， including 14-hydroxyhexadecanoic acid， linoleic acid， and α-linolenic acid （P<0.05）， which suggested that the space capsule environment mainly affected the metabolism of α-linolenic acid and linoleic acid in the rats. Compared with the in-capsule control group， the model group showed lowered levels of fourteen metabolites， including 4-imidazolone-5-propionic acid， isocitric acid/citric acid， and L-tyrosine （P<0.05）， which were recovered after the treatment with Taikong Yangxin pills （P<0.05）. The pathway enrichment analysis revealed that weightlessness induced by tail suspension and drug intervention mainly involved the phenylalanine， tyrosine， and tryptophan biosynthesis， tyrosine metabolism， histidine metabolism， and citric acid cycle. ConclusionThe simulated space capsule environment and simulated weightlessness induced by tail suspension can both affect the metabolism level of rats. Taikong Yangxin pills can ameliorate the metabolic abnormality in the rat model of weightlessness by regulating various amino acids and energy metabolism-related pathways.

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.

Objective To study the effect of practicing traditional Chinese medicine(TCM)guidance on the health in weightless conditions based on the examination results of the TCM diagnostic instrument.Methods 6 subjects in weightless conditions practiced TCM guidance for 14 consecutive days,once a day for 8 minutes each time.The Digital TCM Diagnostic Instrument and TCM Syndrome Diagnosis Scale were used to collect information before and after their practice of TCM guidance through diagnostic methods of observation,palpation and inquiry according to TCM theory.The data such as the degree of virtual-reality,pulse rate,and characteristic parameters of pulse diagrams h3/h1,h4/h1,t1,h1/t1 were processed and analyzed,and the changes before and after the practice were compared.Results Compared with before the practice,the degree of deficiency syndrome was significantly reduced after practicing TCM guidance(P<0.05),the pulse rate was significantly decreased(P<0.01),and the pulse diagnosis parameters h3/h1 and t1 were significantly decreased(P<0.05),while h4/h1 and h1/t1 showed no significant changes.Conclusion Practicing TCM guidance in weightless conditions is helpful for enhance cardiovascular regulatory function,correcting symptom bias,adjusting the body's balance state,and has a positive effect on health.

Objective:To investigate the surgical strategy for giant neurofibromas in the trunk with the goal of precise treatment of superficial tumors.Methods:We retrospectively analyzed the patients with giant neurofibroma of the trunk who admitted to the Department of Plastic Surgery, Southwest Hospital of Army Medical University from January 2021 to March 2023. All patients were treated with "AISS" strategy: (1) autologous blood storage; (2) interventional embolization of the key blood supply artery of the tumor; (3) surgical resection of the tumor; (4) skin graft was harvested from the tumor to repair the secondary defect. Patient demographics, autologous blood storage volume, specific blood vessels and methods of interventional embolization, intraoperative blood loss, intraoperative blood transfusion, complications, and tumor recurrence at follow-ups were documented.Results:A total of 5 patients were enrolled, including 4 males and 1 female, aged 22-32 years. The tumors size ranged from 21 cm×20 cm to 76 cm×66 cm, which were located in the trunk (neck, chest, waist, sacrococcygeal region). The volume of autologous blood storage ranged from 800 to 1 600 ml before the operation. The main blood supply vessels of the tumor were embolized before the operation, including: internal thoracic artery, intercostal artery, external thoracic artery, lumbar artery, inferior epigastric artery, iliolumbar artery and internal iliac artery. All patients underwent radical resection. The intraoperative blood loss was 150-3 000 ml. Patients were transfused with their autologous blood during the operation. There were no severe intraoperative hemorrhage, adverse effects of blood transfusion or infection were not noted. A small skin graft necrosis was noticed in the bilateral iliac fossa in one patient, which was subsequently resolved through dressing change and blade-thickness skin graft transplantation. No tumor recurrence was found during the follow-up period (6-24 months).Conclusion:"AISS" strategy not only safely and accurately treat giant neurofibroma of trunk, but also effectively reduce the intraoperative blood loss and complications, repair of huge wounds in one stage, preventing the recurrence rate of tumors and improving patient satisfaction.

In December 2021, a male patient with a large-scale tissue defect in the lower abdomen and multiple abdominal wall hernias caused by a serious traffic accident was admitted to the Department of Plastic Surgery, the First Affiliated Hospital of Army Medical University. The tensor fascia lata myocutaneous flap combined with anterolateral thigh flap was used to repair abdominal wall sunken deformity and abdominal wall hernia successfully. Five months of follow-up showed satisfactory appearance with no recurrence of abdominal wall hernia.

Cryoablation (CRA) and microwave ablation (MWA) are two main local treatments for hepatocellular carcinoma (HCC). However, which one is more curative and suitable for combining with immunotherapy is still controversial. Herein, CRA induced higher tumoral PD-L1 expression and more T cells infiltration, but less PD-L1^highCD11b⁺ myeloid cells infiltration than MWA in HCC. Furthermore, CRA had better curative effect than MWA for anti-PD-L1 combination therapy in mouse models. Mechanistically, anti-PD-L1 antibody facilitated infiltration of CD8⁺ T cells by enhancing the secretion of CXCL9 from cDC1 cells after CRA therapy. On the other hand, anti-PD-L1 antibody promoted the infiltration of NK cells to eliminate PD-L1^highCD11b⁺ myeloid cells by antibody-dependent cell-mediated cytotoxicity (ADCC) effect after CRA therapy. Both aspects relieved the immunosuppressive microenvironment after CRA therapy. Notably, the wild-type PD-L1 Avelumab (Bavencio), compared to the mutant PD-L1 atezolizumab (Tecentriq), was better at inducing the ADCC effect to target PD-L1^highCD11b⁺ myeloid cells. Collectively, our study uncovered the novel insights that CRA showed superior curative effect than MWA in combining with anti-PD-L1 antibody by strengthening CTL/NK cell immune responses, which provided a strong rationale for combining CRA and PD-L1 blockade in the clinical treatment for HCC.
