RESUMO

Important forensic diagnostic indicators of sudden death in coronary atherosclerotic heart dis-ease,such as acute or chronic myocardial ischemic changes,sometimes make it difficult to locate the ischemic site due to the short death process,the lack of tissue reaction time.In some cases,the de-ceased died of sudden death on the first-episode,resulting in difficulty for medical examiners to make an accurate diagnosis.However,clinical studies on coronary instability plaque revealed the key role of coronary spasm and thrombosis caused by their lesions in sudden coronary death process.This paper mainly summarizes the pathological characteristics of unstable coronary plaque based on clinical medi-cal research,including plaque rupture,plaque erosion and calcified nodules,as well as the influencing factors leading to plaque instability,and briefly describes the research progress and technique of the atherosclerotic plaques,in order to improve the study on the mechanism of sudden coronary death and improve the accuracy of the forensic diagnosis of sudden coronary death by diagnosing different patho-logic states of coronary atherosclerotic plaques.

RESUMO

ObjectiveTo analyze the clinical characteristics and the use of traditional Chinese medicine (TCM) therapy in cancer patients with COVID-19, and to provide reference for making TCM prevention and treatment strategies and determining diagnosis and treatment priorities for patients with malignant tumors in the COVID-19 epidemic. MethodsThe medical records of 225 malignant tumor cases with COVID-19 who were admitted to 7 national research centers from January 1st to 20th, 2023 were retrospectively collected, and the main symptoms and duration after infection, nucleic acid negative conversion time, use of TCM therapy, and changes in adverse reactions after resuming anti-tumor treatment were analyzed. ResultsA total of 222 malignant tumor patients with COVID-19 were included in the analysis, involving 205 mild cases and 17 moderate cases. The top four most frequently reported clinical symptoms were fever (165 cases), expectoration or dry cough (99 cases), decreased appetite (95 cases) and fatigue (85 cases), of which 40 expectoration or dry cough cases , 37 fatigue cases and 29 decreased appetite cases lasted for more than 14 days. One hundred and five patients with nucleic acid detection report had a median negative conversion time of 14 days. The nucleic acid negative conversion time was significantly longer in patients with lung cancer compared to those with digestive system malignant tumors, and in those with myelosuppression than those without (P<0.01). During the infection period, 47.30% (105/222) of the patients used Chinese patent medicine, and 21.17% (47/222) were treated with herbal decoctions. The use of TCM in patients during the prevention and rehabilitation period, was 1.80%(4/222) and 7.21%(16/222), respectively. Fifty-five patients resumed anti-tumor treatment after nucleic acid negative conversion, and received TCM simultaneously. Observed adverse reactions, including gastrointestinal reactions, bone marrow suppression, and neurotoxicity, were all grade 1 to 2, and no new adverse events occurred during follow-up. ConclusionCertain malignant tumor patients with COVID-19 had prolonged symptoms and nucleic acid negative conversion time Rational use of TCM can help to promote the rehabilitation of the patients and ensure the smooth process of anti-tumor treatment after infection.

RESUMO

AIM: To construct column-line plots to predict survival in elderly patients with early-stage HER2-positive breast cancer using the Surveillance, Epidemiology and End Results (SEER) database. METHODS: 5 220 (based on the era of single-targeted therapy) and 1 176 (based on the era of dual-targeted therapy) patients screened in the SEER database were randomized into a training group and an internal validation group. COX proportional risk regression was used to screen survival-related predictors and build a column-line graphical model, and the accuracy and utility of the model were tested using the consistency index (C-index), calibration curves, and time-dependent ROC curves. Patients receiving chemotherapy and non-chemotherapy were statistically paired using two-group propensity score matching, and subgroup analyses were performed on the screened variables. RESULTS: The single-targeted therapy era line graph was constructed from seven variables: age, marital status, T-stage, N-stage, surgery, chemotherapy, and radiotherapy. The dual-targeted therapy era line graph was constructed from five variables: age, AJCC staging, surgery, chemotherapy, and radiotherapy. The results of the subgroup analysis showed that older HER2-positive breast cancer patients who received chemotherapy had better OS. CONCLUSION: Based on the SEER database, an accurate column-line graph predicting survival in elderly patients with early-stage HER2-positive breast cancer was established and validated. This study suggests that chemotherapy increases survival benefit in elderly patients.

RESUMO

Objective To quantitatively evaluate the association of short-term exposure to ambient submicron particulate matter (PM1) with hospital admissions for angina in older adults. Methods A case-crossover study was conducted among 46 687 older adults hospitalized for angina from 2016 to 2019 in Guangzhou medical institutions. Grid data on ambient PM1 concentrations in Guangzhou were obtained from the ChinaHighAirPollutants (CHAP) dataset. Exposure to PM1 was assessed according to each subject's residential addresses. Conditional logistic regression model was used to analyze the the exposure-response association between PM1 and hospital admissions for angina. Results From 2016 to 2019, the average exposure level of PM1 on the same day of hospital admissions (lag 0) for angina was 21.0 ± 11.5 μg/m3. The results of main model analysis showed that lag 0 day exposure to ambient PM1 was significantly associated with a higher odds of hospital admissions for angina in older adults. Each 10 μg/m3 increase of PM1 exposure level was significantly associated with a 1.31% (95% CI: 0.05%, 2.59%) increased odds of angina admissions. Results from a two-pollutant model adjusting for O3 showed that the association between short-term exposure to PM1 and odds of hospitalization for angina remained stable. According to the results of the above model, it was estimated that the excess hospitalization attributable to ambient PM1 exposure accounted for 2.46% (95% CI: 0.09%, 4.76%) of the total admissions in Guangzhou during 2016-2019, corresponding to 1539 (95% CI: 54, 2976) admissions. No significant effect modification on the associations was observed by sex, age, or season. Conclusion Short-term exposure to ambient PM1 was significantly associated with an increased odds of hospital admissions for angina in older adults.

RESUMO

Objective@#: Blood-blister aneurysms (BBAs) of the internal carotid artery (ICA) are challenging lesions with high morbidity and mortality rates. Although research on BBAs is well documented in different populations, the study of BBAs in the Tibetan population is extremely rare. This study aimed to evaluate the characteristics of BBAs and analyze the treatment modalities and long-term outcomes in the Tibetan population in comparison with the Han population. @*Methods@#: The characteristics of patients with BBAs of the ICA from January 2009 to January 2021 at our institution were reviewed. The features of aneurysms, treatment modalities, complications, and follow-up outcomes were retrospectively analyzed. @*Results@#: A total of 130 patients (41 Tibetan and 89 Han patients) with BBAs of the ICA who underwent treatment were enrolled. Compared with the Han group, the Tibetan group significantly demonstrated a high ratio of BBAs among ICAs (8.6%, 41/477 vs. 1.6%, 89/5563; p<0.05), a high ratio of vasospasm (34.1%, 14/41 vs. 6.7%, 6/89; p=0.001), a high risk of ischemic events (43.9%, 18/41 vs. 22.5%, 20/89; p<0.05), and a low ratio of good outcomes (modified Rankin scale, 0–2) at the 1-year follow-up (51.2%, 21/41 vs. 74.2%, 66/89; p<0.05). The multivariate regression model showed that ischemic events significantly contributed to the prediction of outcomes at 1 year. Further analysis revealed that microsurgery and vasospasm were associated with ischemic events. @*Conclusion@#: In comparison with Han patients, the Tibetan population had a high ratio of BBA occurrence, a high incidence of ischemic events, and a high ratio of poor outcomes. The endovascular approach showed more benefits in BBA patients.

RESUMO

This study aimed to explore the potentiating effect and mechanism of the extract of Jingfang Granules(JFG) on the activation of macrophages. The RAW264.7 cells were treated with JFG extract and then stimulated by multiple agents. Subsequently, mRNA was extracted, and reverse transcription-polymerase chain reaction(RT-PCR) was used to measure the mRNA transcription of multiple cytokines in RAW264.7 cells. The levels of cytokines in the cell supernatant were detected by enzyme-linked immunosorbent assay(ELISA). In addition, the intracellular proteins were extracted and the activation of signaling pathways was determined by Western blot. The results showed that JFG extract alone could not promote or slightly promote the mRNA transcription of TNF-α, IL-6, IL-1β, MIP-1α, MCP-1, CCL5, IP-10, and IFN-β, and significantly enhance the mRNA transcription of these cytokines in RAW264.7 cells induced by R848 and CpG in a dose-dependent manner. Furthermore, JFG extract also potentiated the secretion of TNF-α, IL-6, MCP-1, and IFN-β by RAW264.7 cells stimulated with R848 and CpG. As revealed by mechanism analysis, JFG extract enhanced the phosphorylation of p38, ERK1/2, IRF3, STAT1, and STAT3 in RAW264.7 cells induced by CpG. The findings of this study indicate that JFG extract can selectively potentiate the activation of macrophages induced by R848 and CpG, which may be attributed to the promotion of the activation of MAPKs, IRF3, and STAT1/3 signaling pathways.

RESUMO

This study identified the anti-depression targets of Kaixin San(KXS) in the brain tissue with "target fishing" strategy, and explored the target-associated pharmacological signaling pathways to reveal the anti-depression molecular mechanism of KXS. The Balb/c mouse model of depression was established by chronic unpredictable mild stress(CUMS) and the anti-depression effect of KXS was evaluated by forced swimming test and sucrose preference test. KXS active components were bonded to the benzophenone-modified magnetic nanoparticles by photocrosslinking reaction for capturing target proteins from cortex, thalamus and hippocampus of depressive mice. The target proteins were identified by liquid chromatography-mass spectrometry/mass spectrometry(LC-MS/MS). The enrichment analysis on signaling pathways was performed by Cytoscape. The potential biological functions of targets were verified by immunohistochemistry and Western blot assay. The results showed that KXS significantly improved the behavioral indexes. There were 64, 91, and 44 potential targets of KXS identified in cortex, thalamus, and hippocampus, respectively, according to the target identification experiment. The functions of these targets were mainly associated with vasopressin-regulated water reabsorption, salmonella infection, thyroid hormone synthesis, and other signaling pathways. Besides, the results of immunohistochemistry and Western blot showed that KXS up-regulated the expressions of argipressine(AVP) in the cortex, heat shock protein 60(HSP60), cytochrome C oxidase 4(COX4), and thyrotropin-releasing hormone(TRH) in the thalamus, and down-regulated the expressions of tumor necrosis factor-α(TNF-α) and nuclear factor kappa B(NF-κB) p65 in the thalamus. Therefore, KXS may exert anti-depression effect through regulating vasopressin signaling pathway in the cortex and inflammation, energy metabolism, and thyroid hormone signaling pathways in the thalamus, and the effect of KXS on hippocampus is not significant.

RESUMO

This study aimed to identify the direct pharmacological targets of Jingfang Granules in treating infectious pneumonia via "target fishing" strategy. Moreover, the molecular mechanism of Jingfang Granules in treating infectious pneumonia was also investigated based on target-related pharmacological signaling pathways. First, the Jingfang Granules extract-bound magnetic nanoparticles were prepared, which were incubated with lipopolysaccharide(LPS)-induced mouse pneumonia tissue lysates. The captured proteins were analyzed by high-resolution mass spectrometry(HRMS), and the target groups with specific binding to the Jingfang Granules extract were screened out. Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis was used to identify the target protein-associated signaling pathways. On this basis, the LPS-induced mouse model of infectious pneumonia was established. The possible biological functions of target proteins were verified by hematoxylin-eosin(HE) staining and immunohistochemical assay. A total of 186 Jingfang Granules-specific binding proteins were identified from lung tissues. KEGG pathway enrichment analysis showed that the target protein-associated signaling pathways mainly included Salmonella infection, vascular and pulmonary epithelial adherens junction, ribosomal viral replication, viral endocytosis, and fatty acid degradation. The target functions of Jingfang Granules were related to pulmonary inflammation and immunity, pulmonary energy metabolism, pulmonary microcirculation, and viral infection. Based on the in vivo inflammation model, Jingfang Granules significantly improved the alveolar structure of the LPS-induced mouse model of infectious pneumonia and down-regulated the expressions of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6). Meanwhile, Jingfang Gra-nules significantly up-regulated the expressions of key proteins of mitochondrial function COX Ⅳ and ATP, microcirculation-related proteins CD31 and Occludin, and proteins associated with viral infection DDX21 and DDX3. These results suggest that Jingfang Gra-nules can inhibit lung inflammation, improve lung energy metabolism and pulmonary microcirculation, resist virus infection, thus playing a protective role in the lung. This study systematically explains the molecular mechanism of Jingfang Granules in the treatment of respiratory inflammation from the perspective of target-signaling pathway-pharmacological efficacy, thereby providing key information for clinical rational use of Jingfang Granules and expanding potential pharmacological application.

RESUMO

Kawasaki disease (KD), also known as mucocutaneous lymph node syndrome, is a systemic acute vasculitis belonging to autoimmune disease. Up to now, the specific pathogenesis of this disease remains unclear, and it may involve various factors such as immune response, inflammatory response, and vascular endothelial injury caused by the activation of the nuclear factor-kappa B (NF-κB) signaling pathway. In particular, children with KD and cardiac injury tend to have a poor prognosis, and researchers hope to explore the specific pathogenesis of cardiac injury in KD to provide new options for clinical diagnosis and treatment and reduce the incidence rate of this disorder. This article reviews the recent research on the role of the NF-κB signaling pathway in cardiac injury in children with KD, so as to provide a basis for future studies.

RESUMO

Objective: For patients with atrial fibrillation (AF) complicated with acute coronary syndrome (ACS), both anticoagulant and antiplatelet therapy should be applied, but the use of anticoagulation therapy is still poor in these patients in China. The purpose of this study was to explore the status and adherence of antithrombotic therapy in AF patients with ACS and the impact on 1 year clinical outcomes. Methods: Patients with AF hospitalized for ACS were retrospectively included from 6 tertiary hospitals in China between July 2015 and December 2020. According to the use of anticoagulant drugs at discharge, patients were divided into two groups: anticoagulant treatment group and non-anticoagulant treatment group. Logistic regression model was used to analyze the main factors influencing the use of anticoagulant drugs in patients with atrial fibrillation complicated with ACS. Major adverse cardiac events (MACEs) were defined as all-cause death, non-fatal myocardial infarction or coronary revascularization, and ischemic stroke and Bleeding Academic Research Consortium (BARC) 3 bleeding events were also collected at 1 year after discharge. After propensity score matching, Cox proportional hazards models and Kaplan-Meier analysis were used to evaluate the effect of anticoagulant treatment and non-anticoagulant treatment on 1-year prognosis. The patients were divided into different groups according to whether anticoagulation was performed at discharge and follow-up, and the sensitivity of the results was analyzed. Results: A total of 664 patients were enrolled, and 273 (41.1%) were treated with anticoagulant therapy, of whom 84 (30.8%) received triple antithrombotic therapy, 91 (33.3%) received double antithrombotic therapy (single antiplatelet combined with anticoagulant), and 98 (35.9%) received single anticoagulant therapy. Three hundred and ninety-one (58.9%) patients were treated with antiplatelet therapy, including 253 (64.7%) with dual antiplatelet therapy and 138 (35.3%) with single antiplatelet therapy. After 1∶1 propensity score matching between the anticoagulant group and the non-anticoagulant group, a total of 218 pairs were matched. Multivariate logistic regression analysis showed that history of diabetes, HAS-BLED score≥3, and percutaneous coronary intervention were predictors of the absence of anticoagulant therapy, while history of ischemic stroke and persistent atrial fibrillation were predictors of anticoagulant therapy. At 1-year follow-up, 218 patients (79.9%) in the anticoagulant group continued to receive anticoagulant therapy, and 333 patients (85.2%) in the antiplatelet group continued to receive antiplatelet therapy. At 1-year follow-up, 36 MACEs events (13.2%) occurred in the anticoagulant group, and 81 MACEs events (20.7%) in the non-anticoagulant group. HR values and confidence intervals were calculated by Cox proportional risk model. Patients in the non-anticoagulant group faced a higher risk of MACEs (HR=1.802, 95%CI 1.112-2.921, P=0.017), and the risk of bleeding events was similar between the two group (HR=0.825,95%CI 0.397-1.715, P=0.607). Conclusions: History of diabetes, HAS-BLED score≥3, and percutaneous coronary intervention are independent factors for the absence of anticoagulant therapy in patients with AF complicated with ACS. The incidence of MACEs, death and myocardial infarction is lower in the anticoagulant group, and the incidence of bleeding events is similar between the two groups. The risk of bleeding and ischemia/thrombosis should be dynamically assessed during follow-up and antithrombotic regiments should be adjusted accordingly.

RESUMO

Objective To explore the spatial epidemiological characteristics of mortality and probability of premature death caused by chronic obstructive pulmonary disease (COPD) among residents in Pudong New Area of Shanghai from 2010 to 2020, and to provide reference for the formulation of chronic obstructive pulmonary disease prevention and control strategies according to local conditions. Methods The death data of chronic obstructive pulmonary disease were obtained from the local death surveillance system of Pudong New Area. Crude mortality, age-standardized mortality, and probability of premature death caused by COPD in each subdistricts and towns of Pudong New Area were calculated. The geographical information system (GIS) was used to plot the spatial distribution maps of chronic obstructive pulmonary disease death. The trend surface analysis and the spatial autocorrelation analysis were performed to analyze the spatial distribution of chronic obstructive pulmonary disease death. Results The crude mortality, age-standardized mortality and probability of premature death caused by COPD among residents in Pudong New Area between 2010 and 2020 were 58.40/100,000, 22.35/100,000, and 0.26%, respectively. The results of trend surface analysis showed that the crude mortality, age-standardized mortality and probability of premature death caused by COPD gradually increased from north to south. In the east-west direction, the crude mortality, age-standardized mortality, and probability of premature death showed an upward trend from west to east. The global autocorrelation analysis suggested that there existed a positive spatial autocorrelation for the crude mortality, age-standardized mortality, and probability of premature death. The local spatial autocorrelation analysis showed that the high-high clustering areas of COPD crude mortality, standardized mortality and premature mortality were all located in the rural areas of the southeast of Pudong New Area. Conclusion There are urban and rural differences in the mortality of chronic obstructive pulmonary disease among residents in Pudong New Area from 2010 to 2020. The residents living in rural southeast coast of Pudong New Area are more seriously affected by chronic obstructive pulmonary disease and should be paid more attention.

RESUMO

Objective:To explore the diagnostic value of the toxicant and drug detection in clinical poisoning diseases and analyze the clinical characteristics of patients with positive poison test.Methods:This study was a multicenter retrospective cohort study. Sampling and clinical information data were collected between October 1, 2020 and September 30, 2022 from 41 tertiary hospitals in and around Jiangsu province. The clinical characteristics of patients with positive toxicology tests were analyzed, and the correlation between the drug sampling situation and the test results was analyzed..Results:A total of 895 patients with clinical diagnosis or suspected poisoning were enrolled in this study. Among them, 652 patients had positive results, accounting for 72.85%. Among all positive patients, 506 patients were exposed to a single poison and 147 patients were exposed to multiple poisons. The top three poisons were pesticide herbicides (202 cases, 30.98%), sedative and psychotropic drugs (151 cases, 23.16%), and pesticide insecticides (97 cases, 14.88%). Among 541 patients with clear exposure history, the positive rate was 78.19%, and among 354 patients with unclear exposure history, the positive rate was 64.69%. The top three poisons (drugs) of patients with unclear exposure history were sedative and psychotropic (82, 12.58%), herbicide (26, 3.99%), and rodenticide (22, 3.37%). Patients who admitted to hospital for unexplained consciousness disorder, abnormal blood coagulation function and multiple organ dysfunction were more likely to obtain positive poison test results.Conclusions:There is uncertainty in the exposure history of poisoning diseases, so it is necessary to improve the detection of toxic substances as soon as possible. Toxicant testing should be considered when patients have impaired consciousness, abnormal coagulation function and multiple organ dysfunction.

RESUMO

Objective:To explore the relationship between self-perceptions of aging and cognitive function, and the mediating and moderating effect of loneliness among them.Methods:A multi-stage stratified sampling was conducted in Jinzhou from September to November 2021, and 318 community-based elderly were included.General data questionnaire, the brief ageing perceptions questionnaire (BAPQ), UCLA loneliness scale(UCLA-LS) and mini-mental state examination (MMSE) were applied to all subjects.IBM SPSS 25.0 software was used to conduct independent sample t-test, analysis of variance and Pearson correlation analysis, and Bootstrap program of AMOS 22.0 was used to analyze the mediation effect.The model in SPSSAU on-line analysis program was used to test the moderating effect. Results:The average scores of self-perceptions of aging, loneliness and cognitive function were (44.85±12.48), (41.70±8.73) and (24.87±3.40) respectively.And 65 of 318 subjects had cognitive impairment, and the detection rate was 20.44%(65/318). Self-perceptions of aging, loneliness and cognitive function scores were significantly correlated between each other(all P<0.05). Self-perceptions of aging had a negative effect on cognitive function ( β=-0.467, P<0.01). Self-perceptions of aging had a positive effect on loneliness ( β=0.585, P<0.01). Loneliness had a negative effect on cognitive function ( β=-0.234, P<0.01). The indirect standardization effect of loneliness between self-perceptions of aging and cognitive function was -0.137, and the mediating effect accounted for 22.68% of the total effect.Loneliness played a moderating role between self-perceptions of aging and cognitive function ( β=-0.114, t=-2.26, P=0.025). Conclusion:Self-perceptions of aging and loneliness can predict the cognitive function in the elderly, and loneliness plays a mediating role between self-perceptions of aging and cognitive function.Early detection of negative senility emotion and loneliness of the elderly will play a positive role in preventing the occurrence of cognitive impairment.

Objective:To investigate the correlation between the degree of hepatic fibrosis and early neurological deterioration (END) after intravenous thrombolysis in patients with acute ischemic stroke (AIS) and its predictive value.Methods:Patients with AIS received intravenous thrombolysis at Nanjing Jiangbei Hospital from January 2018 to March 2023 were retrospectively included. Hepatic fibrosis-4 index (FIB-4) was used to evaluate the degree of hepatic fibrosis in patients. FIB-4 ≥ 2.67 was defined as severe hepatic fibrosis. END was defined as an increase of ≥4 from baseline on the National Institutes of Health Stroke Scale (NIHSS) score within 24 h after intravenous thrombolysis. The relevant factors of END were analyzed through univariate analysis and multivariate logistic regression model. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of FIB-4 for END. Results:A total of 313 patients were included, of which 184 (58.8%) were male, aged 64.8±11.8 years old. The median baseline NIHSS score was 6 (interquartile range, 4-9), and the median FIB-4 was 1.76 (interquartile range, 1.28-2.56). Forty-five patients (14.4%) experienced END. Multivariate logistic regression analysis showed that after adjusting for other confounding factors, higher FIB-4 was significantly independently correlated with END (odds ratio 2.121, 95% confidence interval 1.422-3.162; P=0.001). ROC curve analysis shows that FIB-4 has a good predictive value for END (the area under the curve 0.689, 95% confidence interval 0.595-0.784; P=0.001). The optimal cutoff value of FIB-4 was 1.82, and its sensitivity and specificity in predicting END were 71.1% and 54.9%, respectively. Conclusion:FIB-4 has good predictive value for END in patients with AIS after intravenous thrombolysis.

RESUMO

Objective To study the proteomic profiling of lung and colon during lung injury induced by lipopolysaccharide(LPS).Methods Mice were divided into four groups:the control,LPS,LPS+ Platycodonis Radix(PR)and LPS+ Rhei Radix et Rhizoma(RRR).LPS was injected into the lungs through trachea,and the drugs were given by intragastric injection.The mice were weighed,the faeces of each mouse were determined,and the lungs and colon were isolated for analysis of pathophysiological changes and proteomics.Results ①After 7 days of LPS,the weight of mice decreased,the lung showed inflammatory changes,and the faeces increased.Both PR and RRR can improve the inflammation.②There are lot of proteins was increased in lung mainly involved in gene transcription and in colon mainly involved in mitochondrial,endoplasmic reticulum and metabolism,etc.The up-regulated proteins shared by both lung and colon were involved in myoprotein contraction.PR can inhibit the up-regulated protein more than RRR in lung.③There are large number of proteins were down-regulated in lung involved in cell membrane and in colon involved in nucleic acid binding and ATP binding.The down-regulated proteins shared by both lung and colon were involved in endoplasmic reticulum,nucleic acid binding and cell membrane,etc.The down-regulated proteins in lung by PR are more than those by RRR,which is involved in endoplasmic reticulum,cell membrane,etc.Conclusion LPS-induced lung injury can cause changes in the expression of protein in lung and colon proteins,and the increase in the expression of myoprotein contraction genes may be one of the molecular mechanisms related to lung and colon.

RESUMO

AIM: To investigate the efficacy of epithelial-off accelerated corneal cross-linking(CXL)in the treatment of advanced keratoconus.METHODS: A retrospective study was performed on data collected from 32 patients(43 eyes)with advanced keratoconus who underwent epithelial-off accelerated CXL at Ningxia Eye Hospital from April 2020 to December 2021. Slit-lamp, intraocular pressure, uncorrected visual acuity(UCVA), corrected visual acuity, specular microscope, Pentacam and Corvis ST were tested before and at 1, 3 and 6mo after surgery. Preoperative and postoperative corneal condition, UCVA, best corrected visual acuity(BCVA)and the values of corneal endothelial, maximum keratometry(Kmax), thinnest corneal thickness(TCT), anterior and posterior surfaces of the cornea K1, K2, biomechanically corrected intraocular pressure(bIOP), applanation time 1(A1T), applanation length 1(A1L), applanation velocity 1(A1V), applanation time 2(A2T), applanation length 2(A2L), applanation velocity 2(A2V), highest concavity deformation amplitude(HCDA), radius at highest curvature(HCR), highest concavity peak distance(HCPD)and stiffness parameter at first applanation(SP-A1)were recorded.RESULTS: There were differences between UCVA(LogMAR; 1.06±0.49, 0.78±0.39)and BCVA(LogMAR; 0.48±0.34, 0.38±0.29)before and at 6mo after surgery(P&#x003C;0.05), but there were no differences in corneal endothelial cells(2917.39±288.38 vs. 2959.19±336.27 cells/mm2, P=0.477). There were differences among Kmax, TCT, anterior surface K1 and K2 and posterior surface K1 before and after surgery(P&#x003C;0.05), and all increased at 1mo after surgery then returned to preoperative level at 3mo after surgery, while there was no difference in the posterior K2. Furthermore, there were statistical significance in A1T, HCPD and SP-A1 before and after surgery(P&#x003C;0.05), while there were no statistical significance in A1L, A1V,A2T, A2L, A2V, HCDA, HCR and bIOP(P&#x003E;0.05).CONCLUSION: Epithelial-off accelerated CXL can prevent the progression of keratoconus within half year after surgery, and it has certain safety.

RESUMO

Background/Aims@#The impact of coronavirus disease 2019 (COVID-19) on the management of colorectal cancer (CRC) may worse in elderly population, as almost all COVID-19 deaths occurred in the elderly patients. This study aimed to evaluate the impact of COVID-19 on CRC management in the elderly population. @*Methods@#The numbers of patients who underwent colonoscopy, who visited hospitals or operated for CRC in 2020 and 2021 (COVID-19 era) were compared with those in 2019, according to 3 age groups (≥70 years, 50–69 years, and ≤49 years), based on the nationwide, population-based database (2019–2021) in South Korea. @*Results@#The annual volumes of colonoscopy and hospital visits for CRC in 2020 were more significantly declined in the old age group than in the young age group (both P<0.001). In addition, the annual volume of patients operated for CRC numerically more declined in old age group than in young age group. During the first surge of COVID-19 (March and April 2020), old age patients showed statistically significant declines for the monthly number of colonoscopies (–46.5% vs. –39.3%, P<0.001), hospital visits (–15.4% vs. –7.9%, P<0.001), CRC operations (–33.8% vs. –0.7%, P<0.05), and colonoscopic polypectomies (–41.8% vs. –38.0%, P<0.001) than young age patients, compared with those of same months in 2019. @*Conclusions@#Elderly population are more vulnerable for the management of CRC during the COVID-19 pandemic. Therefore, the elderly population are more carefully cared for in the management of CRC during the next pandemic.
