ABSTRACT
Objective:To investigate the clinical values of progastrin-releasing peptide (Pro-GRP), neuron-specific enolase (NSE), cytokeratin 19 fragment antigen 21-1 (CYFRA21-1), squamous cell carcinoma antigen (SCCA) and human human epididymis protein 4 (HE4) detections in the diagnosis of lung cancer patients.Methods:The clinical data of 200 lung cancer patients who were admitted to the Second Affiliated Hospital of Xuzhou Medical University from January 2020 to December 2021 were retrospectively analyzed. According to the pathological type, the patients were divided into lung adenocarcinoma group (80 cases), lung squamous cell carcinoma group (75 cases) and small cell lung cancer group (45 cases). Fifty patients with benign lung diseases and 50 healthy physical examiners who were admitted to the hospital during the same period were selected. All the subjects were tested for the levels of Pro-GRP, NSE, CYFRA21-1, SCCA and HE4, and the differences of each index level in the subjects of different subgroups were compared. The receiver operating characteristic (ROC) curve was drawn, and using pathological diagnosis result as the gold standard, the diagnostic efficacy of each index alone and in combination for lung cancer was compared.Results:The serum levels of Pro-GRP, NSE, CYFRA21-1, SCCA and HE4 in lung cancer group were higher than those in the benign lung diseases group and the healthy control group (all P < 0.001). There were no statistical differences in the levels of serum Pro-GRP, NSE, CYFRA21-1, SCCA and HE4 between the benign lung diseases group and the healthy control group (all P > 0.05). The levels of Pro-GRP, NSE and HE4 in the small cell lung cancer group were higher than those in the lung adenocarcinoma group and the lung squamous cell carcinoma group (all P < 0.05). NSE and HE4 levels in the lung adenocarcinoma group were higher than those in the lung squamous carcinoma group (both P < 0.05), while CYFRA21-1 and SCCA levels were lower than those in the lung squamous carcinoma group (both P < 0.05). The AUC of lung cancer diagnosed by HE4 was the largest (0.813), the AUC of lung adenocarcinoma diagnosed by HE4 was the largest (0.824), the AUC of lung squamous carcinoma diagnosed by CYFRA21-1 was the largest (0.884), and the AUC of small cell lung cancer diagnosed by NSE was the largest (0.959). The AUC of lung cancer diagnosed by combined detection of 5 indicators was 0.951, the AUC of lung adenocarcinoma and small cell lung cancer diagnosed by combined detection of 5 indicators was 0.975 and 0.996, and the AUC of lung squamous cell carcinoma diagnosed by combined detection of CYFRA21-1, SCCA and HE4 was 0.967. Conclusions:The levels of Pro-GRP, NSE, CYFRA21-1, SCCA, HE4 and other indicators have certain clinical values in the diagnosis of lung cancer and its pathological types, and the combined detection of each index is more valuable than a single index.
ABSTRACT
ObjectivesThe coronavirus disease 2019 (COVID-19) pandemic has led to millions of deaths. Effectively cutting the transmission of COVID-19 is essential to reduce the impact. Previous studies have observed the potential relationship between the built environment and COVID-19 transmission; however, to date, stringent studies investigating these relationships at the individual level are still insufficient. Here, we aim to examine the relationship between household types and COVID-19 infection (or mental health) during the early stages of the pandemic by using the All of Us Research Program COVID-19 Participant Experience (COPE) survey data. DesignBased on 62,664 participants responses to COPE from May to July 2020, we matched the cases of self-reported COVID-19 status, anxiety, or stress, with controls of the same race, sex, age group, and survey version. We conducted multiple logistic regressions between one of the outcomes and household type under the adjustment of other related covariates, such as ethnicity, age, social distancing behavior, and house occupancy. ResultsHousehold type with a shared component was significantly associated with COVID-19 infection (OR=1.19, 95% CI 1.1 to 1.3; p=2x10-4), anxiety (OR=1.26, 95% CI 1.1 to 1.4; p=1.1x10-6), and stress (OR=1.29, 95% CI 1.2 to 1.4, p=4.3x10-10) as compared to free-standing houses after adjusting for the abovementioned confounding factors. Further, frequent nonessential shopping or outings, another indicator of the built environment, was also associated with COVID-19 infection (OR=1.36, 95% CI 1.1 to 1.8; p=0.02), but not associated with elevated mental health conditions. ConclusionOur study demonstrated that the built environment of houses with a shared component tends to increase the risk of COVID-19 transmission, which consequently led to more anxiety and stress for their dwellers. It also suggested the necessity to improve the quality of the built environment through planning, design, and management toward a more resilient society in coping with future pandemics.
ABSTRACT
IntroductionPrior research has reported an increased risk of fatality for cancer patients, but most studies investigated the risk by comparing cancer patients to non-cancer patients among COVID-19 infections. Only a few studies have compared the impact of a COVID-19 infection to non-infection with matched cancer patients and types. Methods & MaterialsWe conducted survival analyses of 4,606 cancer patients with COVID-19 test results from March 16 to October 11, 2020 in UK Biobank and estimated the overall hazard ratio of fatality with and without COVID-19 infection. We also examined the hazard ratios of thirteen specific cancer types with at least 100 patients. ResultsCOVID-19 resulted in an overall hazard ratio of 7.76 (95% CI: [5.78, 10.40], p<10-10) by studying the survival rate of 4,606 cancer patients for 21-days after the tests. The hazard ratio was shown to vary among cancer type, with over a 10-fold increase in fatality rate (false discovery rate[≤]0.02) for melanoma, hematologic malignancies, uterine cancer, and kidney cancer using a stratified analysis on each of the cancer types. Although COVID-19 imposed a higher risk for localized cancers compared to distant metastasis ones, those of distant metastasis yielded higher fatality rates due to their multiplicative effects. ConclusionThe results highlight the importance of timely care for localized and hematological cancer patients and the necessity to vaccinate uninfected patients as soon as possible, particularly for the cancer types influenced most by COVID-19.
ABSTRACT
ObjectiveTo determine the effect of multi-criteria decision analysis (MCDA) on the effect of bundle treatment for severe pneumonia.Methods A prospective historical control observation was conducted. Seventy-five patients with severe pneumonia having received MCDA (from January 2013 to August 2014) were assigned as intervention group. MCDA group was set up by the medical staff. Bundled treatment plan was composed of the MCDA evaluation results, anti-infection, phlegm and other conventional treatment measures which was adjust on time until the patient was transferred out of the respiratory intensive care unit (RICU) or died. Seventy patients with severe pneumonia before receiving MCDA (from August 2010 to December 2012) were set as historical control group. Comparison of general condition before treatment and the incidence of hospital infection, average hospitalization cost, duration of RICU stay and mortality between these two groups were performed.Results There were no statistically significant differences in gender, age, past history, and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score at admission between two groups. Compared with control group, the incidence of hospital infection [1.33% (1/75) vs. 11.43% (8/70),χ2 = 4.723,P = 0.030], mean hospitalization cost in RICU (10 thousand Yuan: 3.44±0.79 vs. 3.76±0.91,t = 2.265, P = 0.025), length of RICU stay (days: 15.01±4.22 vs. 16.92±4.79,t = 2.552,P = 0.012) and mortality in RICU [8.0% (6/75) vs. 21.4% (15/70),χ2 = 5.272,P = 0.032] in intervention group was significantly decreased. Conclusions Application of MCDA in the bundle treatment of severe pneumonia could elevate the scientificalness of decision, and reduce the medical cost. Additionally, MCDA is worth to be generalized because the implementation of guidelines can improve the clinical outcome and prognosis of the patients.
ABSTRACT
Objective To prove the remarkable inhibitive effect of multiple siRNAs targeting a proliferation-inducing ligand (APRIL) on the human colorectal cancer cell.Methods We constructed a multiple short hairpin RNA(shRNA) expression vector containing four shRNAs (pG4) as well as four single one (pGsh644,pGsh1451,pGsh1938,pGsh2231) against APRIL gene in SW480 cell,and then transfected them into the human colorectal cancer cell line by cationic liposome.Ultimately,SW480 were screened by EGFP to obtain expression cell lines.APRIL expression levels including mRNA and APRIL protein were detected after transfected with all different kinds of vectors.Results A multiple shRNA expression vector containing four shRNAs (pG4) and four single ones were successfully constructed.Four single vectors (pGsh644,pGsh1451,pGsh1938,pGsh2231) and the multiple siRNAs expression vector (pG4) all decreased the APRIL mRNA by 56.2％,49.5％ ;50.9％,49.2％ and 79.3％.And APRIL protein expression was also remarkably reduced,especially by multiple siRNAs expression vector(87.5％).Conclusion Multiple siRNAs expression vector produced a more significant knockdown effect of APRIL than the vectors containing only one APRIL shRNA.What we found suggested us using the vector containing multiple shRNA to silence the expression of APRIL might be exploited as a novel therapeutic strategy for tumors.
ABSTRACT
Objective To investigate the effects of a proliferation-inducing ligand(APRIL) on migration and invasion of colorectal cancer (CRC) and matrix metalloproteinases (MMPs) expression in order to observe the role of APRIL in CRC metastasis.Methods The siRNA plasmid vector targeting APRIL gene (siRNA-APRIL) was transfected into SW480 cells and recombinant human APRIL(rhAPRIL) was used to stimulate HCT-116 cells.Tumor cell migration and invasion were measured by Transwell chambers.RT-PCR and ELISA were applied to examine the expression level of MMPs.Results Metastatic and invasive capacities of siRNA-APRIL transfected SW480 were significantly inhibited,and these capacities of APRIL stimulated HCT-116 cells were significantly enhanced compared with their respective controls( all P＜0.05 ),accompanied with the alterations of MMPs mRNA and secreted protein expression( P＜0.05).The number of invading cells of SW480 control and rhAPRIL stimulated HCT-116 was significantly decreased by a MMP inhibitor GM6001 ( P＜0.05 ).Conclusion APRIL facilitates migration and invasion of CRC via regulation of MMPs,which suggests that APRIL might be used as a new target for the intervention and treatment of CRC metastasis.
