Differential Diagnosis of Pathological Type of Peripheral Lung Cancer with Multimodal Contrast-Enhanced Ultrasound.

OBJECTIVE: The goal of the work described here was to investigate the role of multimodal contrast-enhanced ultrasound in the differential diagnosis of peripheral lung cancer. METHODS: From April 2017 to July 2021, 109 patients with confirmed pulmonary malignant lesions who underwent CEUS examination were involved in our study. Seven patients were excluded because of the short duration of CEUS video or unsatisfactory imaging. Finally,102 patients with peripheral lung cancer were enrolled in this study. The maximum diameter of the lesions ranged from 1.6 to 13.0 cm (mean 6.2 ± 2.3 cm). On the basis of the pathological results, the patients were divided into the small cell lung cancer (SCLC) group and non-small cell lung cancer (NSCLC) group (including adenocarcinoma, lung squamous cell carcinoma and large cell neuroendocrine carcinoma). A Logiq E9 ultrasonic machine equipped with a 3.5 to 5.0 MHz C5-1 probe was used. Patient clinical information, CEUS features, CPI patterns and TIC parameters were analyzed and compared between different groups. Statistical analyses were performed with SPSS software and MedCalc software. The receiver operating characteristic curve was plotted. RESULTS: In the differential diagnosis of SCLC and NSCLC, color parametric imaging indicated great performance. NSCLC exhibited a centripetal enhancement pattern more frequently (72.7%), while SCLC exhibited an eccentric enhancement pattern more frequently (92.9%) (p < 0.001). In the differential diagnosis of adenocarcinoma and squamous cell carcinoma, logistic regression analysis revealed that patient age of onset ≤60 y, difference in arrival time between lung and tumor ≤3.8 s, drop time of the time-intensity curve >23.2 s and absence of internal necrosis on CEUS were independent predictors for adenocarcinoma (area under the curve = 0.861). CONCLUSION: In our study, multimodal contrast-enhanced ultrasound provided useful information in the differential diagnosis between small cell lung cancer and non-small cell lung cancer, especially between adenocarcinoma and squamous cell carcinoma.

Beneficial effects of oxymatrine from Sophora flavescens on alleviating Ulcerative colitis by improving inflammation and ferroptosis.

ETHNOPHARMACOLOGICAL RELEVANCE: Sophora flavescens is often used in traditional Chinese medicine for skin issues, diarrhea, and vaginal itching (Plant names have been checked with http://www.the/plant/list.org on Feb 22nd, 2024). Oxymatrine (OY), a major bioactive compound from Sophora flavescens, is commonly used in China to treat ulcerative colitis, but its mechanisms are still unclear. AIM OF THE STUDY: Recent studies have found that the crosstalk between ferroptosis and inflammation is an important mechanism in the pathogenesis of UC. The aim of this study was to investigate the potential underlying mechanisms of OY treatment on DSS-induced ulcerative colitis, specifically focusing on the processes of ferroptosis and inflammation. MATERIALS AND METHODS: Bioinformatics methods were used to identify key targets of OY for ferroptosis and inflammation in ulcerative colitis, based on GEO data and FerrDb database. Then, 4% DSS solution was used to induce UC model. OY's impact on morphological changes was assessed using colon views, Hematoxylin and eosin (HE) staining, and transmission electron microscopy (TEM). Ferroptosis phenotype index and inflammations factors were detected by ELISA or chem-bio detection kits. The screen out hub related genes about ferroptosis and inflammation were verified by RT-PCR, immunohistochemistry (IHC), and western blotting (WB) respectively. RESULTS: Bioinformatics results show that there are 16 key target genes involved in ferroptosis and inflammation interaction of OY treatment for UC, such as IL6, NOS2, IDO1, SOCS1, and DUOX. The results of animal experiments show that OY could depress inflammatory factors (IL-1ß, IL-6, TNF-α, HMGB1, and NLRP3) and reduce iron deposition (Fe2+, GSH). Additionally, OY suppressed the hub genes or proteins expression involved in ferroptosis and inflammation, including IL-1ß, IL-6, NOS2, HIF1A, IDO1, TIMP1, and DUOX2. CONCLUSION: This present study combines bioinformatics, molecular biology, and animal experimental research evidently demonstrated that OY attenuates UC by improving ferroptosis and inflammation, mainly target to the expression of IL-1ß, IL-6, NOS2, HIF1A, IDO1, TIMP1, and DUOX2.

Natural products with potential hypoglycemic activity in T2DM: 2019-2023.

As currently the most common metabolic disease, type 2 diabetes mellitus (T2DM) has shown a continuous increase in the number of patients in recent decades. Most anti-T2DM drugs tend to cause some side effects. Given the pathogenesis of T2DM, natural products have emerged as an important source of anti-T2DM drugs. This article reviews natural products with potential hypoglycemic activity from 2019 to 2023. A total of 200 previously natural products were discovered on SciFinder, PubMed and Web of Science. These products were categorized based on their structural frameworks and their biological activities were summarized. Although the mechanisms of action of most compounds are unclear, these compounds could still serve as candidates for the development of lead compounds. Therefore, further structure and activity research of natural products will significantly contribute to the development of potential anti-T2DM drugs.

The World's consumption of free web-based Otolaryngology-Head and Neck Surgery educational resources: A global assessment of video usage trends.

Objectives: Online educational platforms with open access have seen a growing adoption in the field of medical education. However, the extent of their global usage is still unclear. To fill this knowledge gap, our objective is to examine the usage patterns of two renowned open-access resources in Otolaryngology. This includes identifying the most sought-after topics and understanding the demographics of their users. Methods: Retrospective study of web analytics data between 2016 and 2021 extracted from the Headmirror.com and Mayo Clinic Otolaryngology YouTube channel platforms analyzing demographic and education topic trends via descriptive, geospatial, time-series, t-tests, and ANOVA analyses. Results: Viewership spanned 124 countries in 7 different geographic regions, with 72 countries comprising low- to middle-income countries, mostly represented ages of 25-34 years old, came from high-income countries rather than low-income (p < .001), and used mobile phones followed by computers for device access. Video-educational material comprised of subspecialty topics on Rhinology and Sinus Surgery (25%) at the highest end and Facial Trauma (1%) at the lowest. Controlling for the age of the video content, the most-accessed videos comprised of subspecialty topics on Head and Neck Surgery at the highest end and Laryngology at the lowest with significant differentiation across topics of interest (p < .044). Conclusions: This assessment of web-analytics platforms from two widely used otolaryngology free, online-access materials showed increasing global usage trends with significant differentiating factors along viewership demographics, as well as sought-after subspecialty topics of interest. In turn, our results not only lay the groundwork for characterizing the global otolaryngology audience but also for future development of targeted educational materials and accessibility initiatives aimed at ameliorating global educational disparities in the field.

The associations of food environment with gastrointestinal cancer outcomes in the United States.

BACKGROUND: Social conditions and dietary behaviors have been implicated in the rising burden of gastrointestinal cancers (GIC). The "food environment" reflects influences on a community level relative to food availability, nutritional assistance, and social determinants of health. Using the US Department of Agriculture-Food Environment Atlas (FEA), we sought to characterize the association of food environment on GIC presenting stage and long-term survival. METHODS: Patients diagnosed with GIC between 2013 and 2017 were identified using the SEER database. FEA-scores were based on 282 county-level food security variables, store-restaurant availability, SNAP/WIC enrollment, pricing/taxes, and producer vicinity adjusted-for factors of socioeconomic status, race-ethnicity, transportation access, and comorbidities. Relative FEA rankings across US counties were averaged into a composite score and assigned to patients by county-of-residence. The association of FEA, cancer stage, and survival were analyzed using multiple logistic regression and cox-proportional hazard models relative to White/non-White race/ethnicity. RESULTS: Among 287,148 patients, the most common GIC-sites were colon (n = 97,942, 34%), pancreas (n = 49,785, 17.3%), liver (n = 31,098, 11.0%) and esophagus (n = 16,271, 5.7%). A worse food environment was independently associated with increased odds of late-stage diagnosis (esophageal odds ratio [OR]: 1.03, 95% confidence interval [CI]: 1.01-1.05; hepatic OR: 1.06, 95% CI: 1.03-1.08; pancreatic OR: 1.04, 95% CI: 1.01-1.06) among all patients; in contrast, food environment was associated with colorectal cancer stage among non-White patients only (OR: 1.04, 95% CI: 1.03-1.06). Worse food environment was associated with worse 3-year survival (colon OR: 1.03, 95% CI: 1.01-1.04; hepatic OR: 1.12, 95% CI: 1.08-1.17; gastric OR: 1.07, 95% CI: 1.01-1.13). Similar associations were noted relative to overall survival among the entire cohort (biliary tract hazard ratio [HR]: 1.03, 95% CI: 1.01-1.05; esophageal HR: 1.02, 95% CI: 1.01-1.04; hepatic HR: 1.07, 95% CI: 1.06-1.09; pancreatic HR: 1.04, 95% CI: 1.02-1.05; rectum HR: 1.03, 95% CI: 1.01-1.04; gastric HR: 1.05, 95% CI: 1.03-1.07), as well as among non-White patients (biliary HR: 1.04, 95% CI: 1.01-1.07; colon HR: 1.03, 95% CI: 1.01-1.05; esophageal HR: 1.05, 95% CI: 1.02-1.08; hepatic HR: 1.08, 95% CI: 1.06-1.10) (all p < 0.003). CONCLUSIONS: Food environment was independently associated with late-stage tumor presentation and worse 3-year and overall survival among GIC patients. Interventions to address inequities across communities relative to food environments are needed to alleviate disparities in cancer care.

Assessing social vulnerabilities of salivary gland cancer care, prognosis, and treatment in the United States.

BACKGROUND: Salivary gland cancers (SGC)-social determinants of health (SDoH) investigations are limited by narrow scopes of SGC-types and SDoH. This Social Vulnerability Index (SVI)-study hypothesized that socioeconomic status (SES) most contributed to SDoH-associated SGC-disparities. METHODS: Retrospective cohort of 24 775 SGCs assessed SES, minority-language status (ML), household composition (HH), housing-transportation (HT), and composite-SDoH measured by the SVI via regressions with surveillance and survival length, late-staging presentation, and treatment (surgery, radio-, chemotherapy) receipt. RESULTS: Increasing social vulnerability showed decreases in surveillance/survival; increased odds of advanced-presenting-stage (OR: 1.12, 95% CI: 1.07, 1.17), chemotherapy receipt (OR: 1.13, 95% CI: 1.03, 1.23); decreased odds of primary surgery (0.89, 0.84, 0.94), radiotherapy (0.91, 0.85, 0.97, p = 0.003) for SGCs. Trends were differentially correlated with SES, ML, HH, and HT-vulnerabilities. CONCLUSIONS: Through quantifying SDoH-derived SGC-disparities, the SVI can guide targeted initiatives against SDoH that elicit the most detrimental associations for specific sociodemographics.

Influence of Social Vulnerability in Treatment and Prognosis of Squamous Cell Carcinoma of the Tongue.

OBJECTIVE: To investigate the association of social determinants of health (SDoH) in squamous cell carcinoma of the tongue in the United States and to evaluate the real-world contribution of specific disparities. STUDY DESIGN: Retrospective cohort study. SETTING: United States. METHODS: The Centers for Disease Control and Prevention-Social Vulnerability Index (SVI) and National Cancer Institute-Surveillance, Epidemiology, and End Results Program database were used to study 62,103 adult tongue squamous cell carcinoma patients from 1975 to 2017. Regression analysis assessed trends in months of follow-up and survival across social vulnerability and 4 subcategories of social vulnerability. RESULTS: As overall SVI score increases (increased social vulnerability), there is a significant decrease in the average length of follow-up (22.95% decrease from 63.99 to 49.31 months; P < .001) across patients from the lowest and highest social vulnerability groups. As overall SVI score increases, there is a significant decrease in the average months of survival (28.00% decrease from 49.20 to 35.43 months; P < .001). There is also a significantly greater odds ratio (OR = 1.05; P < .001) of advanced cancer staging upon presentation at higher SVI scores. Patients with higher SVI scores have a lower OR (0.93; P < .001) of receiving surgery as their primary treatment when compared to patients with lower SVI scores. Patients with higher SVI scores also have a significantly greater OR (OR = 1.05; P < .001) of receiving chemotherapy as their primary treatment when compared to patients with lower SVI scores. CONCLUSION: Increased social vulnerability is shown to have a detrimental impact on the treatment and prognosis of patients with squamous cell carcinoma of the tongue.

Assessment of social vulnerability impact in care and prognosis of sinonasal cancers in the United States.

KEY POINT: Social determinants of health interactively influence sinonasal cancer care and prognosis. Housing-transportation and socioeconomic status showed the largest associations with disparities. The social vulnerability index can reveal the social determinants of sinonasal cancers.

Assessment of Social Vulnerabilities of Care and Prognosis in Adult Ocular Melanomas in the US.

BACKGROUND: Prior works have studied the impact of social determinants on various cancers but there is limited analysis on eye-orbit cancers. Current literature tends to focus on socioeconomic status and race, with sparse analysis of interdisciplinary contributions. We examined social determinants as measured by the Centers for Disease Control and Prevention (CDC) Social Vulnerability Index (SVI), quantifying eye and orbit melanoma disparities across the United States. METHODS: A retrospective review of 15,157 patients diagnosed with eye-orbit cancers in the Surveillance, Epidemiology, and End Results (SEER) database from 1975 to 2017 was performed, extracting 6139 ocular melanomas. SVI scores were abstracted and matched to SEER patient data, with scores generated by weighted averages per population density of county's census tracts. Primary outcome was months survived, while secondary outcomes were advanced staging, high grading, and primary surgery receipt. RESULTS: With increased total SVI score, indicating more vulnerability, we observed significant decreases of 23.1% in months survival for melanoma histology (p < 0.001) and 19.6-39.7% by primary site. Increasing total SVI showed increased odds of higher grading (odds ratio [OR] 1.20, 95% confidence interval [CI] 1.02-1.43) and decreased odds of surgical intervention (OR 0.94, 95% CI 0.92-0.96). Of the four themes, higher magnitude contributions were observed with socioeconomic status (26.0%) and housing transportation (14.4%), while lesser magnitude contributions were observed with minority language status (13.5%) and household composition (9.0%). CONCLUSIONS: Increasing social vulnerability, as measured by the CDC SVI and its subscores, displayed significant detrimental trends in prognostic and treatment factors for adult eye-orbit melanoma. Subscores quantified which social determinants contributed most to disparities. This lays groundwork for providers to target the highest-impact social determinant for non-clinical factors in patient care.

Analyzing County-level Social Vulnerabilities of Head and Neck Melanomas in the United States.

OBJECTIVES: Studies addressing social determinants of health (SDH) in head-neck melanomas (HNM) have only assessed incidence with increasing socioeconomic status. None have investigated a wider scope of SDH or their summed influence on affecting HNM prognosis and follow-up care. METHODS: This retrospective cohort study analyzed 374,138 HNM in adults from 1975 to 2017 from the NCI-Surveillance, Epidemiology, and End Results Program (NCI-SEER) database. Utilizing the NCI-SEER database, Social Vulnerability Index (SVI) scores were matched to county of residence upon diagnosis. Univariate linear regressions were performed on length of care (months of follow-up/surveyed) and prognosis (months survival) across various SDH/SVI scores of socioeconomic status, minority and language status, household composition, housing and transportation, and their total composite. RESULTS: With increasing overall SVI score, which indicates increasing social vulnerability, months of follow-up showed significant decreases ranging from 0.04% to 27.63% compared with the lowest vulnerability groups, with the highest differences in nodular melanomas and the lowest with malignant melanomas in giant pigmented nevi. Similarly, months survival significant decreases ranged from 0.19% to 39.84% compared with the lowest SVI scores, with the highest difference in epithelioid cell melanomas and the lowest in amelanotic melanoma. Comprising this overall score trend, decreases with socioeconomic status, minority-language status, household composition, and housing-transportation contributed differentially per histology subtype. CONCLUSIONS: Our data highlight significant negative trends in HNM prognosis and care with higher total social vulnerability while showing which SDH-themes quantifiably contribute more to these differences. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:185-190, 2024.

Reduction in NGAL at 48 h predicts the progression to CKD in patients with septic associated AKI: a single-center clinical study.

BACKGROUND: In this study, our objective was to investigate the predictive value of serum and urine fluctuations of neutrophil gelatinase-associated lipid transporters (NGAL) in relation to the progression of chronic kidney disease (CKD) among patients with septic associated AKI (SA-AKI). METHODS: A total of 425 SA-AKI patients were enrolled in this study and divided into the recovery group (n = 320) and the AKI-to-CKD group (n = 105) based on 3-month follow-up data. The serum and urine NGAL levels on the day of AKI diagnosis (T0) and 48 h after anti-AKI treatment (T1) were recorded and calculated. RESULTS: The levels of NGAL in serum and urine were found to be higher in the AKI-to-CKD group compared to the recovery group at T1 point (P < 0.05). The reductions of NGAL at 48 h in serum and urine were lower in the AKI-to-CKD group than those observed in the recovery group (P < 0.05). In comparison to T0, a significant decrease was noted for both serum and urine NGAL levels on T1 among patients who recovered from AKI (P < 0.05), whereas no such trend was observed among those with AKI-to-CKD transition (P > 0.05). After adjusting age, sex, and BMI through partial correlation analysis, the reduction of serum NGAL was found to be most strongly associated with the transition from AKI to CKD. ROC analysis showed an AUC of 0.832 for serum NGAL reduction, with a cut-off value of - 111.24 ng/ml and sensitivity and rates of 76.2% and 81.2%, respectively. Logistic regression analysis indicated that a reduction of serum NGAL ≥ - 111.24 ng/ml was the early warning indicator for the progression of CKD in SA-AKI patients. CONCLUSION: The reduction of serum NGAL following 48 h of anti-AKI therapy represents a distinct hazard factor for the advancement of CKD in patients with SA-AKI, independent of other variables.

Influence of Medicaid Expansion on Head and Neck Squamous Cell Carcinoma Presentation and Survival.

OBJECTIVE: To compare head and neck squamous cell carcinoma stage at presentation and survival in Medicaid-expanded states versus nonexpanded states. STUDY DESIGN: Retrospective cohort. SETTING: Northwestern University Feinberg School of Medicine. METHODS: The Head and Neck with human papillomavirus Status Database within the Surveillance, Epidemiology, and End Results (SEER) Program was queried for cases of head and neck squamous cell carcinoma (HNSCC) diagnosed in the years 2010 to 2016. Cases were grouped according to their respective state Medicaid expansion status. Multivariable logistic regressions and multivariable Cox proportional hazards models were used to evaluate associations with stage IV disease and survival. RESULTS: Compared to nonexpanded states, Medicaid-expanded states had a significantly larger proportion of Medicaid patients (20.3% vs 16.7%, P = .0009) and a significantly smaller proportion of uninsured patients (1.7% vs 10.1%, P < .0001). The case selection process resulted in 2215 patients meeting inclusion criteria. In multivariable analysis, cases under Medicaid expansion were 31% less likely to present with stage IV disease compared to cases in nonexpanded states (odds ratio: 0.69, 95% confidence interval [CI]: 0.51-0.93). In the multivariable Cox proportional hazards model, cases under Medicaid expansion had significantly better mortality outcomes and were 32% less likely to die compared to cases in nonexpanded states (hazard ratio: 0.68, 95% CI: 0.55-0.84). CONCLUSION: Medicaid expansion is associated with fewer stage IV cases and improved survival of HNSCC cases. These findings support continued efforts to expand Medicaid coverage.

Social Vulnerability Association with Thyroid Cancer Disparities in the United States.

Background: As thyroid cancer incidence rises, it is increasingly valuable to recognize disparities in treatment and diagnosis. Prior investigations into social determinants of health (SDoH) are limited to pediatric populations or studies looking at single factors such as race or environmental influences. Utilizing the CDC-social vulnerability index and SEER-patient database to assess the amalgamated, real-world influence of varied SDoH and their quantifiable impact on thyroid cancer disparities across the United States. Methods: In a retrospective cohort study, 199,340 adult thyroid cancer patients from 1975 to 2017 were assessed for significant regression trends in months of follow-up/surveillance, survival, late staging, and treatment receipt across thyroid cancer-subtypes with increasing overall social vulnerability, as well as in 15 SDoH variables regarding socioeconomic status, minority-language status, household composition, and housing-transportation across all the U.S. counties while accounting for sociodemographic regional differences. Results: With increasing overall social vulnerability, decreases in months of follow-up were observed with patients with papillary, follicular, medullary, oncocytic, and anaplastic thyroid cancer (p = 0.001). Comparing lowest with highest vulnerability cohorts, relative decreases in months of surveillance ranged from 55.6% (14.5-6.5 months) with anaplastic to 17% (108.6-90.2) with oncocytic. Socioeconomic status vulnerabilities, followed by vulnerabilities in household composition and housing-transportation type, contributed to these overall trends. Similar survival decreases occurred across all thyroid cancer patients, ranging from 55.9% (9.6-4.2) with anaplastic to 28.3% (97-69.5) with oncocytic. Minority-language status vulnerabilities and housing-transportation types largely contributed to these trends. Increasing overall vulnerability was associated with increased odds of advanced staging for papillary (odds ratio [OR] = 1.07 [confidence interval, CI 1.03-1.12]) and decreased odds of indicated treatment via surgery (lowest, medullary: 0.91 [CI 0.84-0.99]), radiation therapy (lowest, anaplastic: 0.88 [CI 0.82-0.93]), and chemotherapy (lowest, oncocytic: 0.81 [CI 0.67-0.98]) were observed. Vulnerabilities in minority-language status and housing-transportation, followed by socioeconomic status vulnerabilities, were differential contributors to these overall vulnerability trends. Conclusions: Our results show significant detriments in thyroid cancer care and prognosis in the United States with increasing overall social vulnerability while identifying which SDoH quantifiably contribute more to disparities in inter-relational, real-world-like contexts.

Associations of social vulnerability with truncal and extremity melanomas in the United States.

BACKGROUND: Prior studies in social determinants (SDoH) of truncal-extremity melanomas (TEM) have analyzed race, income, and environmental factors relative to their effect on health disparities. However, they are limited by the narrow scopes of SDoH and study population, while lacking analyses of interrelational contribution of SDoH on TEM disparities. METHODS: This retrospective cohort study of adult TEM patients (1975-2017) assessed linear regression trends in months of survival, as well as logistic regression trends in advanced presenting stage, surgery, and chemotherapy receipt across TEM subtypes with increasing overall social vulnerability and vulnerability in 15 SDoH variables grouped into socioeconomic status (SES), minority-language status (ML), household composition (HH), and housing-transportation (HT) themes measured by the SVI. SVI measures are ranked/compared across all US counties for relative vulnerability in a specific SDH and their total composite while accounting for sociodemographic-regional differences. RESULTS: Across 325 760 TEM patients, increasing overall social vulnerability demonstrated significant decreases in the survival period for 7/13 TEM histology types (p < 0.001), with relative decreases in the survival period as high as 44.0% (67.0-37.5 months) for epithelioid cell. SES and HH were the highest-magnitude contributors to these overall trends. For many patients with TEM, increased odds of advanced presenting stage (highest with acral-lentiginous: odds ratio [OR], -1.18; 95% confidence interval [CI], 1.02-1.36), decreased odds of indicated surgery receipt (lowest with amelanotic, 0.79; 0.71-0.87), and increased odds of indicated chemotherapy (highest with melanoma in giant nevi: 1.50; 1.01-2.44) were observed; SES and ML followed by HH and HT contributed to these trends. CONCLUSIONS: There were detriments in TEM care & prognosis in the United States with increasing social vulnerability. Identifying which SDH quantifiably are associated more with disparities in interrelational, real-world contexts is important to provide nuance to inform future research and initiatives to address TEM disparity.

Clinical Efficacy of Qiangli Pipa Syrup in Treating Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease and Its Influence on Pulmonary Function and Levels of Interleukin 6,C-reactive Protein and Procalcitonin / 广州中医药大学学报

Objective To investigate the clinical efficacy of Qiangli Pipa Syrup for the treatment of patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD),and to observe its effects on pulmonary function and interleukin 6(IL-6),C-reactive protein(CRP)and procalcitonin(PCT)levels in the patients.Methods Eighty patients with AECOPD of phlegm-heat obstructing the lung syndrome were randomly divided into the observation group and the control group,with 40 patients in each group.Patients in the control group were treated with conventional western medicine,and patients in the observation group were treated with Qiangli Pipa Syrup on the basis of treatment for the control group.Both groups were treated for 5 days.The two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome scores(including cough,expectoration,shortness of breath,and wheezing),pulmonary function parameters[the forced expiratory volume in one second(FEV1)and the ratio of FEV1 to the forced vital capacity(FVC)(FEV1/FVC)],blood gas indicators[arterial partial pressure of oxygen(PaO2),blood oxygen saturation(SaO2)and arterial partial pressure of carbon dioxide(PaCO2)]and the levels of the inflammatory factors of IL-6,CRP,and PCT before and after treatment.Moreover,the clinical efficacy and safety of the patients in the two groups were evaluated.Results(1)After 5 days of treatment,the total effective rate of the observation group was 95.00%(38/40),and that of the control group was 77.50%(31/40).The intergroup comparison(tested by chi-square test)showed that the therapeutic effect of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the TCM syndrome scores of cough,expectoration,shortness of breath,and wheezing in the two groups were reduced compared with those before treatment(P＜0.05),and the reduction in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the pulmonary function parameters of FEV1/FVC and FEV1 in the two groups were improved compared with those before treatment(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the blood gas indicators of PaO2 and SaO2 levels in the two groups were increased compared with those before treatment(P＜0.05),and the PaCO2 level was decreased compared with that before treatment(P＜0.05).The increase of PaO2 and SaO2 levels and the decrease of PaCO2 level in the observation group were significantly superior to those in the control group(P＜0.05).(5)After treatment,the serum levels of inflammatory factors of IL-6,CRP,and PCT in the two groups were lower than those before treatment(P＜0.05),and the reduction in the observation group was significantly superior to that in the control group(P＜0.05).(6)The incidence of adverse reactions in the observation group was 10.00%(4/40),while that in the control group was 7.50%(3/40).There was no significant difference between the two groups(P＞0.05).Conclusion Qiangli Pipa Syrup exerts certain effect in treating patients with AECOPD of phlegm-heat obstructing the lung syndrome,which can effectively relieve the clinical symptoms,improve the pulmonary function and blood gas indicators,and inhibit inflammatory response of the patients,with high safety profile.

The mechanism of emodin inhibiting YAP1 and FOXD1 in gastric cancer AGS cells and its related study / 实用医学杂志

Objective To explore the possible mechanism of emodin in inhibiting proliferation,migration,and invasion of AGS cells and in suppressing the expressions of YAP1 and FOXD1.Methods Normal gastric cell GES-1 and gastric cancer cell AGS were cultured with different concentrations of emodin.CCK8 test,scratch test and Transwell assay were used to verify changes in the biological phenotype of AGS cells.TCGA database was applied to analyze expressions of HK2,YAP1 and FOXD1 in gastric cancer tissues and normal gastric tissues.Western blotting method was used to detect the impacts of emodin on HK2,YAP1 and FOXD1 proteins in AGS cells.Exogenous pyruvic acid was added to verify the changes in YAP1 and FOXD1.Results The IC50 of emodin was significantly higher in GES-1 cells than in AGS cells(P<0.05).CCK8 proliferation test,scratch test,and Transwell assay showed that emodin significantly inhibited the biological abilities of AGS(P<0.05 for comparisons).Analysis on the TCGA bioinformatics database found that the expression of key enzymes HK2 in the glycolysis pathway and oncogenes YAP1 and FOXD1 was significantly higher in gastric cancer tissues than in normal gastric tissues(P<0.05 for comparisons).Emodin significantly inhibited the protein expressions of key glycolytic enzymes HK2 and oncogenes YAP1 and FOXD1(P<0.05 for comparisons).With supplement of exogenous glycolytic metabolite pyruvate,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased(P<0.05 for comparisons).Conclusions Emodin has a significant pharmacological inhibitory effect on gastric cancer AGS cells,markedly suppressing their biological phenotype.Emodin not only significantly inhibits the key enzyme HK2 in glycolysis metabolism,but also the protein expressions of oncogenes YAP1 and FOXD1.With the addition of exogenous pyruvate to enhance the glycolytic metabolic pathway,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased.The above results suggest a close association of YAP1 and FOXD1 with glycolytic metabolism.Emodin may inhibit oncogenes YAP1 and FOXD1 through the glycolytic metabolism of gastric cancer AGS cells.

Effect of mindfulness-based therapy on postoperative cognitive function and sleep quality in elderly patients after surgery under local anesthesia / 四川精神卫生

BackgroundPostoperative cognitive dysfunction （POCD） is a common complication in elderly patients after surgery， and has a great impact on postoperative rehabilitation of patients. ObjectiveTo explore the effect of mindfulness-based therapy on cognitive function and sleep quality in elderly patients after surgery under local anesthesia， so as to provide references for reducing their incidence risk of POCD and improving sleep quality. MethodsThe simple random sampling method was utilized to select 78 elderly patients who underwent surgery under local anesthesia in The Third Hospital of Mianyang from March 2022 to March 2023. Participants were assigned into study group and control group， each with 39 cases. All patients were subjected to conventional treatment and nursing interventions， and study group added mindfulness-based therapy on this basis. Mini-Mental State Examination （MMSE） was administered to patients on 1 day before surgery， and on the 1st， 3rd and 5th day after surgery. Pittsburgh Sleep Quality Index （PSQI） was employed on 1 day before surgery and on the 3rd day after surgery. ResultsMMSE scores revealed a significant time effect， group effect and time×group interaction effect （F=78.251， 197.071， 371.915， P<0.05）. Analysis of simple effect denoted that study group scored higher on MMSE on the 1st， 3rd and 5th day after surgery compared with control group， with statistical significance （t=-3.579， -1.764， -0.253， P<0.05）. Study group reported lower incidence rates of POCD on the 1st， 3rd and 5th day after surgery compared with control group， with statistical significance （χ2=2.631， 3.471， 5.135， P<0.05）. On the 3rd day after surgery，study group scored lower on PSQI than control group（P<0.05）， and PSQI total score， sleep latency， subjective sleep quality， daytime dysfunction and hypnotic drug use factor scores of study group were lower than baseline， with statistical significance（F=43.175， 12.594， 11.092， 4.579， 3.514， P<0.01）. ConclusionMindfulness-based therapy may have certain value in reducing incidence of POCD and improving sleep quality in elderly patients who underwent surgery under local anesthesia.

Clinical safety and validity analysis of retrograde new endo-scopic visual field in miniature pigs / 中国现代普通外科进展

Objective:To study the clinical safety and validity of retrograde new endoscopic field of vision in miniature pigs.Methods:6 live miniature pigs were selected as study subjects,En-doscopic Retrograde New View(ERNV)was selected.The performance,image quality and intraoper-ative and postoperative complications were evaluated.To evaluate whether all the experimental ani-mals could complete the relevant endoscopy.Verify ERNV's operating performance,including whether the duodenoscope can enter the biliary tract smoothly,and made sure whether the injection,suction,and instrument channels were unobstructed.Choledochoscope image clarity,color resolu-tion,image deformation and distortion,accurate evaluation of lumen conditions and clear observation of mucosal surface conditions were analyzed.Whether there were operant injuries such as bleeding and perforation,as well as adverse events such as respiratory depression and cardiac arrest.The sur-vival status and adverse reactions of all pigs were observed.Results:The choledochoscope was successfully inserted into the bile duct of 6 miniature pigs.The product had good operation perfor-mance and could enter the bile duct through the duodenoscope smoothly.The injection,suction and instrument channels were relatively smooth.In addition,the endoscopic images are clear,with better color resolution,and without image deformation and distortion,which can realize accurate evaluation of the conditions in the lumen and observe the mucosal surface conditions more clearly.No bile duct stenosis or dilatation occurred in all miniature pigs,and the bile duct mucosa was smooth,without hyperemia and edema,and no abnormal thickening or bending of mucous vessels.During the exami-nation,there were no operational injuries such as bleeding and perforation,and no adverse events such as respiratory depression and cardiac arrest occurred.The vital signs of all miniature pigs tended to be stable after operation,and the survival state was good,and there were no complications such as cholangitis,bleeding and perforation.Conclusion:ERNV has good clinical safety and efficacy,ex-cellent operation performance and excellent image quality,and is worthy of clinical application.
