Objective:To investigate the clinical experience about the transconjunctival lower eyelid blepharoplasty with correction of the eyelid orbital sulcus deformity.Methods:This group received 67 cases from June 2016 to July 2018, including 3 males and 64 females. The average age was 22 years. All the cases were diagnosed as lower eyelid bag with different degrees of fat herniation after orbital septum, with no or slight lower eyelid skin relaxation. Orbital sulcus of different degree appeared with outline of bony orbital margin, or accompanied by underdevelopment of the suborbital region. Through a transconjunctival incision or with short external canthal incision, the adipose mass was fully exposed behind the anterior wall of lower eyelid, the arcuate edge was released, and the pedicled orbital fat was transferred to the gap between the orbital eyelid sulcus and fixed in the lower orbital margin. If there was insufficient fat behind the orbital septum, a retroauricular fascia graft was used to make up.Results:No postoperative complications occured in all cases. After followed up for more than 3-month, 3 of 67 cases showed mild fat bulging pouch deformity in bilateral eyelids and 1 case was in unilateral eyelid. In other cases, deformity of the pouch and the eyelid orbital sulcus were improved significantly, and dynamic expression (orbicularis muscle contraction) showed no local uplift in lower eyelid morphology.Conclusion:The transconjunctival lower eyelid blepharoplasty with correction of the eyelid orbital sulcus deformity can obtain good clinical results in lower eyelid area.

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 discuss the feasibility of using online and offline combined multidisciplinary team (MDT) diagnosis-treatment mode in cancers diagnosis and treatment by comparing the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode.Methods:A total of 168 esophageal cancer patients collected from March 17, 2020 to May 17, 2020 were took as the research objects in Shandong Cancer Hospital and Institute, through whom the consistency of the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode was evaluated. The clinical characteristics of patients with changed comprehensive diagnosis and treatment plans, such as age, Karnofsky performance status (KPS) score, whether combined with basic diseases, whether received anti-tumor treatment before and tumor location were analyzed, so as to explore the mechanism to improve the efficiency on the basis of quality assurance.Results:The results showed that 86.3% (145/168) of the comprehensive diagnosis and treatment plans obtained by offline MDT diagnosis-treatment mode were consistent with online diagnosis-treatment MDT mode. Cases with inconsistent comprehensive diagnosis and treatment plans were characterized by elderly (> 69 years) ( χ2=4.250, P=0.039), KPS score≥80 ( χ2=15.520, P<0.001) and combined with underlying disease ( χ2=7.135, P=0.008). Through further analysis, the changed cases were also characterized as with inadequate auxiliary examination or complex in imaging. Conclusion:The online and offline combined MDT diagnosis-treatment mode is feasible. For the patients characterized of elderly (> 69 years old), KPS score ≥80, combined with underlying diseases, with incomplete auxiliary examination or complex in imaging, the offline MDT diagnosis-treatment mode should be adopted or supplemented.

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.
