Objective To investigate the effects of LINC01355 on the proliferation,apoptosis,and invasion of oral squamous cell car-cinoma(OSCC)cells via the miR-545-5p/forkhead box D1(FOXD1)signaling pathway.Methods Cal-27 cells were cultured in vitro and randomly separated into the control group,si-LINC01355(transfected with LINC01355 siRNA)group,pc-LINC01355(transfected with LINC01355 overexpression plasmid)group,si-NC+miR-545-5p-NC+pc-NC(transfected with LINC01355 siRNA negative control,miR-545-5p negative control and empty plasmid)group,and si-LINC01355+miR-545-5p inhibitor(transfected with LINC01355 siRNA and miR-545-5p inhibitor)group.After transfection,quantitative real-time PCR was applied to detect the expression of LINC01355,miR-545-5p,and FOXD1 in cells.The Cal-27 cells transfected into groups were then subcutaneously inoculated to construct nude mouse models of transplanted tumors in each group,and the growth of the transplanted tumors was measured.The CCK-8 method,flow cytom-etry,and Transwell assay were applied in order to detect cell proliferation,apoptosis,and invasion,respectively.Immunohistochemical staining was applied to detect the expression of epithelial-mesenchymal transition(EMT)related proteins Vimentin and E-cadherin in cells.Western blotting was applied to detect the expression of cell proliferation related proteins(proliferating cell nuclear antigen[PCNA],C-myc),apoptosis related proteins(cleaved cysteinyl aspartate-specific proteases-3[cleaved caspase-3],BCL-2-associated X protein[Bax]),and FOXD1 protein.A dual-luciferase reporter assay was used to identify the relationship between LINC01355 and the miR-545-5p/FOXD1 signaling pathway.Results Compared with the control group,the expression of LINC01355 and FOXD1 mRN A,proliferation activity,number of invasions,positive expression of Vimentin protein,expression of PCNA,C-myc and FOXD1 protein,and transplanted tumor volume reduced(All P＜0.05);the expression of miR-545-5p,apoptosis rate,cleaved caspase-3 and Bax protein expression,and positive expression of E-cadherin protein increased(All P＜0.05)in the si-LINC01355 group.The trend of changes in the various indica-tors of the pc-LINC01355 group was opposite to that of the si-LINC01355 group.Compared with the si-LINC01355 group,the expression of LINC01355 and FOXD1 mRNA,prolife ration activity,number of invasions,positive expression of Vimentin protein,expression of PCNA,C-myc and FOXD1 proteins,and the transplanted tumor volume in the si-LINC01355+miR-545-5p inhibitor group increased(All P＜0.05),whereas the expression of miR-545-5p,apoptosis rate,cleaved caspase-3 and Bax protein expression,and positive expression of E-cadherin protein decreased(All P＜0.05).LINC01355 was able to downregulate miR-545-5p expression in Cal-27 cells and miR-545-5p was able to downregulate FOXD1 expression.Conclusion LINC01355 promotes OSCC cell proliferation and invasion,and inhibits apoptosis by targeting the miR-545-5p/FOXD1 signaling pathway.

Aimed to find a safe and effective drug to replace nitroimidazole drugs in aquaculture pro-duction for the prevention and treatment of Trichomoniasis in pigeons,which can improve the eco-nomic benefits of meat pigeon breeding and ensure food safety.Firstly,Trichomonas was isolated and cultured from the crop of diseased pigeons and identified.After stable passage,a quantitative method for in vitro detection of Trichomonas was established by combining an automated cell counter and quantitative real-time PCR technology.To prepared the drug,powders of Sophora fla-vescent and Philodendron were made into herbal water extracts(SFPA)and mixed with copper sulfate(CS)solution.Then added the drug to the culture medium of Trichomonas to determine the effective concentration of it.A total of 135 pairs each of Silver King and Mimas breeding pigeons in the same laying period were selected and randomly divided into three groups,with 6 replicates in each group and 15 pairs of breeding pigeons in each replicate.Four days before brooding,the three groups were fed with 200 mL of pure water,0.5 g/L metronidazole(MDZ)solution,and a mixed solution of 30 g/L SFPA and 0.5 g/L CS,respectively.The feeding experiment lasted for 26 d.Results showed that the mixed solution of SFPA and CS had a significant killing effect on Trichomonas in vitro(P＜0.05).Feeding the drug to breeding pigeons significantly reduced the in-fection rate of breeding pigeons by Trichomonas(P＜0.05).The drug had no significant effect on the serum biochemical indexes,antioxidant properties,immunoglobulin levels of breeding pigeons,the average cage weight,immune organ indexes,meat quality and slaughter performance of squabs(P＞0.05).The results suggested that adding SFPA and CS to pigeons can effectively prevent and treat Trichomoniasis and improve production performance.It can replace nitroimidazole drugs without affecting the immune level of breeding pigeons and the weight,immune level,slaughter performance and meat quality of squabs,thereby reduce drug residues in poultry products and en-hance the food safety.

Objective To investigate the application value of point-of-care lung ultrasound (POC-LUS) scoring in selecting respiratory support treatment modalities for neonatal infectious pneumonia (NIP). Methods A total of 89 NIP patients were selected as the study subjects and divided into control group (no assisted ventilation) with 46 cases, noninvasive group (noninvasive assisted ventilation) with 28 cases, and invasive group (invasive mechanical ventilation) with 15 cases based on the degree of dyspnea and blood gas analysis results. The POC-LUS scores of the three groups were compared, and the correlations of POC-LUS scores with arterial oxygen partial pressure [p_a(O₂)] and arterial carbon dioxide partial pressure [p_a(CO₂)] were analyzed. Receiver operating characteristic (ROC) curves were plotted to assess the predictive efficacy of POC-LUS scores for the need for noninvasive assisted ventilation or invasive mechanical ventilation in NIP patients. Results The POC-LUS scores of the noninvasive group and the invasive group were (31.7±7.3) and (42.1±8.0), respectively, which were higher than (21.5±7.3) of the control group. Additionally, the score of the invasive group was higher than that of the noninvasive group (P < 0.05). Correlation analysis revealed a significant negative correlation between POC-LUS scores and p_a(O₂) (r=-0.802, P < 0.05), and a significant positive correlation with p_a(CO₂) (r=0.807, P < 0.05). ROC curve analysis showed that the area under the curve (AUC) of POC-LUS scores for predicting the need for noninvasive assisted ventilation and invasive mechanical ventilation were 0.918 (95%CI, 0.862 to 0.973) and 0.938 (95%CI, 0.889 to 0.987), respectively. The sensitivity was 0.767 and 0.933, and the specificity was 0.935 and 0.824, with optimal cutoff values of 29.5 and 31.5, respectively. Conclusion POC-LUS scoring can quantitatively assess the severity of lung lesions in NIP patients and serves as a guiding tool for clinicians in selecting assisted ventilation treatment modalities.

Purpose To investigate the expression and po-tential clinical value of heat shock protein 90α(Hsp90α)in co-lon adenocarcinoma.Methods The expression level of Hsp90αin colon adenocarcinoma and its relationship with clinicopatho-logical features,prognosis and immune cell infiltration were ana-lyzed by bioinformatics and immunohistochemistry.The prolifer-ation ability of colon cancer cells before and after Hsp90AA1 knockout was detected by CCK-8 cell proliferation assay and plate cloning assay.Results The bioinformatics tools showed that Hsp90AA1 was abnormally higher in colon cancer tissues than adjacent tissues,and the higher the expression level,the worse the prognosis of patients.The expression of Hsp90AA1 was positively correlated with the infiltration levels of CD4+T cells(Th2),CD8+T cells,myeloid inhibitory cells,Tregs cells,neutrophils,macrophages,M1 macrophages and M2 macropha-ges.Immunohistochemical results showed that the expression of Hsp90α in colon cancer tissues was significantly higher than in its adjacent tissues.The expression of Hsp90α was related to age(P＜0.05),not related to gender,tumor size,location,clini-cal classification,differentiation degree,tumor node metastasis,lympho-vascular invasion,perineural invasion(P＞0.05).The high expression of Hsp90α was an independent risk factor for the prognosis of colon cancer patients.The results of cell experi-ments showed that Hsp90AA1 knockout inhibited the growth and proliferation of colon cancer cells.Conclusion Hsp90α is highly expressed in colon adenocarcinoma,which may be a po-tential molecular marker for poor prognosis of colon adenocarci-noma.

Objective    To systematically evaluate the risk factors for postoperative pulmonary infection in patients with esophageal cancer. Methods    CNKI, Wangfang Data, VIP, CBM, PubMed, EMbase, The Cochrane Library were searched from inception to January 2021 to collect case-control studies, cohort studies and cross-sectional studies about risk factors for postoperative pulmonary infection in patients with esophageal cancer. Two researchers independently conducted literature screening, data extraction and quality assessment. RevMan 5.3 software and Stata 15.0 software were used for meta-analysis. Results    A total of 20 articles were included, covering 5 409 patients of esophageal cancer. The quality score of included studies was 6-8 points. Meta-analysis results showed that age (MD=1.99, 95%CI 0.10 to 3.88, P=0.04), age≥60 years (OR=2.68, 95%CI 1.46 to 4.91, P=0.001), smoking history (OR=2.41, 95%CI 1.77 to 3.28, P<0.001), diabetes (OR=2.30, 95%CI 1.90 to 2.77, P<0.001), chronic obstructive pulmonary disease (OR=3.69, 95%CI 2.09 to 6.52, P<0.001), pulmonary disease (OR=2.22, 95%CI 1.16 to 4.26, P=0.02), thoracotomy (OR=1.77, 95%CI 1.32 to 2.37, P<0.001), operation time (MD=14.08, 95%CI 9.64 to 18.52, P<0.001), operation time>4 h (OR=3.09, 95%CI 1.46 to 6.55, P=0.003), single lung ventilation (OR=3.46, 95%CI 1.61 to 7.44, P=0.001), recurrent laryngeal nerve injury (OR=5.66, 95%CI 1.63 to 19.71, P=0.006), and no use of patient-controlled epidural analgesia (PCEA) (OR=2.81, 95%CI 1.71 to 4.61, P<0.001) were risk factors for postoperative pulmonary infection in patients with esophageal cancer. Conclusion    The existing evidence shows that age, age≥60 years, smoking history, diabetes, chronic obstructive pulmonary disease, pulmonary disease, thoracotomy, operation time, operation time>4 h, single lung ventilation, recurrent laryngeal nerve injury, and no use of PCEA are risk factors for postoperative pulmonary infection in patients with esophageal cancer. Due to the limitation of the quantity and quality of included literature, the conclusion of this study still needs to be confirmed by more high-quality studies.

Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.
