Objective To observe the influence of different altitudes on the basic vital signs of cardiopulmonary resuscitation (CPR) rescuers before and after CPR.Methods The experiment was completed in the Simulated Cabin for Special Environment of Northwest of China. Ninety healthy adult medical staff in General Hospital of Xinjiang Command were randomly and equally divided into 3 groups: plain (normal oxygen), 3700-meter high altitude and 4300-meter high altitude. According to the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, the values of heart rate (HR), mean arterial pressure (MAP), respiration rate (RR), arterial oxygen saturation (SpO2), before and after 1 CPR cycle were recorded for statistical analysis and their changes were compared.Results The HR and RR significantly increased (P<0.05), but MAP and SpO2 did not change significantly (P>0.05) in the three groups. The HR and RR was faster in 4300 meter high-altitude than in 3700 meter high-altitude (P<0.05), and was faster in 3700 meter high-altitude than in the plain (P<0.05). But there was no significant difference between the three groups in MAP and SpO2 (P>0.05).Conclusions With the elevation of the altitude, HR and RR may significantly increase in CPR rescuers, but there is no significant influence on MAP and SpO2.

Objective To investigate the risk factors and prognosis on the post-resuscitation multiple organ dysfunction syndrome(MODS) after successful cardiopulmonary resuscitation(CPR).Methods Clinical data of 53 patients who were suffered with cardiac arrest(CA) and undergone successful CPR with return of spontaneous circulation(ROSC) were analyzed. Results There were 48 patients accompanied with MODS(90.6%),and among them,35 patients died in hospital(66.0%).All the 10 patients with CPR interval ≥6min were accompanied with MODS and they died in hospital.There were 43 patients who underwent CA immediately and of them,38 patients were accompanied with MODS.The incidence and mortality of MODS in the patients with CA-ROSC interval 0.05).Conclusion The risk factors such as ROSC interval ≥6 min,AC-ROSC interval ≥10min and the SIRS after ROSC are significantly associated with the incidence of MODS.The organic function of the patients should be evaluated promptly.

Objective To investigate the predictive values of serum complement C3, C4 and cholesterol levels in the prognosis of patients with sepsis. Methods The clinical data of all the patients with sepsis admitted to the Department of Critical Care Medicine of the General Hospital of Xinjiang Military Command from January 2015 to January 2017 were retrospectively analyzed. The levels of serum complement C3, C4, cholesterol, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure score (SOFA), etc. were recorded within 24 hours after admission, the patients were divided into survival group and death group according to the 28-day prognosis, and the differences in various indexes between the two groups were compared respectively;the predictive efficacies of C3, C4 and cholesterol levels in the prognosis of sepsis patients were evaluated by plotting receiver operating characteristic curves (ROC). Results Finally, 120 patients with sepsis were enrolled, including 57 patients in the survival group and 63 patients in the death group. Compared with the survival group, the APACHE Ⅱscore and the SOFA score of the death group were increased significantly (APACHE Ⅱ score: 20.29±5.90 vs. 15.32±5.98, SOFA score: 7.62±3.11 vs. 5.16±2.50, both P < 0.01), however, serum C3, C4 and cholesterol levels were obviously decreased [C3 (g/L): 0.67±0.22 vs. 0.82±0.24, C4 (g/L): 0.17±0.05 vs. 0.20±0.06, cholesterol (mmol/L): 2.77±1.23 vs. 3.46±1.02, all P < 0.01]. ROC curve analyses showed: each of the following items, complement C3, C4, and cholesterol, alone predicting the prognosis of sepsis patients, the area under ROC curve (AUC) and 95% confidence interval (95%CI) were as follows: AUC = 0.680 (95%CI = 0.583-0.777, P = 0.001), AUC =0.657 (95%CI = 0.560-0.754, P = 0.003), and AUC = 0.711 (95%CI = 0.619-0.804, P < 0.001) respectively; when complement C3, C4 and cholesterol combination to predict the prognosis of patients with sepsis, the resulting predictive value was better than the predictive value results obtained by each one of the items or each combination of any two of them (the AUC of C3+C4+cholesterol was 0.725, 95%CI = 0.633-0.817, P < 0.001; the AUC of C3+C4 was 0.697,95%CI = 0.603-0.791, P < 0.001; the AUC of C3 + cholesterol was 0.718, 95%CI = 0.626-0.811, P < 0.001; the AUC of C4+cholesterol was 0.722, 95%CI = 0.629-0.815, P < 0.001). Conclusion Using combination of serum complement C3, C4 and cholesterol levels to predict the prognosis of patients with sepsis may obtain important predicting value, that can provide a reference to clinical doctors.

Objective: To investigate the role of long non-coding RNA double homeobox A pseudogene 9 (DUXAP9) in head and neck squamous cell carcinoma (HNSCC) and to evaluate the expression level, molecular function and mechanism of DUXAP9 in HNSCC cells. Methods: Differential expression of lncRNAs between normal and tumor tissues in HNSCC tissues were screened using lncRNA microarray, the expression level of DUXAP9 in HNSCC tissues and its relationship with prognosis were analyzed in the TCGA database. The expression levels of DUXAP9 in HNSCC tissues and cell lines were detected using qRT-PCR. The function in HNSCC cells after DUXAP9 silencing was evaluated using the CCK-8 assay, wound healing assay, Transwell migration assay and subcutaneous xenograft assay in nude mice. Changes in the transcription and translation of epithelial-mesenchymal transition (EMT)-related proteins in head and neck squamous cell carcinoma cells after DUXAP9 silencing were detected using qRT-PCR and Western blot. Results: lncRNA microarray results showed that, compared to adjacent normal tissues, DUXAP9 was abnormally upregulated in HNSCC tissues. Analysis from TCGA database showed that, compared to HNSCC patients with low DUXAP9 expression, HNSCC patients with high DUXAP9 expression had poorer survival. The relative expression of DUXAP9 in HNSCC tissues and 4 HNSCC cell lines increased compared to paired adjacent normal tissues as detected using qRT-PCR. Silencing DUXAP9 significantly inhibited the proliferation, migration and expression of EMT-related genes in HNSCC cells. The silencing of DUXAP9 significantly inhibited subcutaneous tumorigenesis of the HNSCC cell line CAL27 in nude mice. Conclusion Silencing DUXAP9 significantly inhibited the proliferation of HNSCC cells and subcutaneous xenografts in nude mice. DUXAP9 may mediate the migration of head and neck squamous cell carcinoma cells via the EMT pathway.

Tumor progression is closely related to tumor tissue metabolism and reshaping of the microenvironment. Oral squamous cell carcinoma (OSCC), a representative hypoxic tumor, has a heterogeneous internal metabolic environment. To clarify the relationship between different metabolic regions and the tumor immune microenvironment (TME) in OSCC, Single cell (SC) and spatial transcriptomics (ST) sequencing of OSCC tissues were performed. The proportion of TME in the ST data was obtained through SPOTlight deconvolution using SC and GSE103322 data. The metabolic activity of each spot was calculated using scMetabolism, and k-means clustering was used to classify all spots into hyper-, normal-, or hypometabolic regions. CD4T cell infiltration and TGF-β expression is higher in the hypermetabolic regions than in the others. Through CellPhoneDB and NicheNet cell-cell communication analysis, it was found that in the hypermetabolic region, fibroblasts can utilize the lactate produced by glycolysis of epithelial cells to transform into inflammatory cancer-associated fibroblasts (iCAFs), and the increased expression of HIF1A in iCAFs promotes the transcriptional expression of CXCL12. The secretion of CXCL12 recruits regulatory T cells (Tregs), leading to Treg infiltration and increased TGF-β secretion in the microenvironment and promotes the formation of a tumor immunosuppressive microenvironment. This study delineates the coordinate work axis of epithelial cells-iCAFs-Tregs in OSCC using SC, ST and TCGA bulk data, and highlights potential targets for therapy.
