Objective To analyze and summarize the clinical characteristics of foreign body incarceration in upper digestive tract, and to explore the risk factors of its complications. Methods The clinical data of patients with foreign bodies in the upper digestive tract treated in the Affiliated Hospital of Zunyi Medical University between January 1, 2012 and December 31, 2021 were retrospectively analyzed, including demographic data, foreign body type, incarceration site, incarceration time, causes, symptoms, treatment methods and complications of foreign body incarceration. Logistic regression analysis was used to explore the risk factors of complications. Results A total of 721 patients were finally included, ranging in age from 3 months to 90 years old, with an average age of 26.76 years. The proportion of foreign bodies in the upper digestive tract in patients ≤14 years old was the highest (51.18%), and the duration of foreign body incarceration<12 hours was the highest (55.34%). The most common sharp foreign bodies in the upper digestive tract were animal bones (228 cases), and the most common round shaped foreign bodies were coins (223 cases). The most common impaction site was the upper esophageal segment (85.02%). 105 patients (14.56%) had complications, and perforation was the most common (5.55%). Logistic regression analysis showed that age [odds ratio (OR)=0.523, 95% confidence interval (CI) (0.312, 0.875), P=0.014], foreign body type [OR=0.520, 95%CI (0.330, 0.820), P=0.005], incarceration site [OR=2.347, 95%CI (1.396, 3.947), P=0.001], incarceration time [OR=0.464, 95%CI (0.293, 0.736), P=0.001] were the influencing factors of complications. Conclusions The majority of foreign bodies in the upper digestive tract are animal bones. The incidence of complications increase in patients with age ≥ 60 years, sharp foreign body edges, incarceration in the upper segment of the esophagus, and long incarceration time. It is recommended to remove the sharp foreign bodies incarcerated in the upper segment of the esophagus from the elderly as soon as possible.
Objective To investigate the risk factors for lymph node metastasis in cT1N0M0 stage squamous cell lung cancer and develop a logistic regression model to predict lymph node metastasis. Methods A retrospective study was conducted on patients with cT1N0M0 stage lung squamous cell carcinoma in our department from August 2017 to October 2022. The correlation between basic clinical data, imaging data, and pathological data and lymph node metastasis was analyzed. Univariate and multivariate logistic regression analyses were employed for risk factor analysis. Receiver operating characteristic curves and the Hosmer-Lemeshow test were utilized to evaluate the model’s discrimination and calibration. The Bootstrap method with 1 000 resamples was employed for internal validation of the model. Results Tumor location of central-type, tumor differentiation, cytokeratin 19 fragment (CYFRA21-1) levels, and tumor size were independent risk factors for lymph node metastasis in cT1N0M0 stage squamous cell lung cancer. The optimal cutoff values for tumor size and CYFRA21-1 levels were determined to be 2.05 cm and 4.20 ng/mL, respectively. The combination of tumor location, CYFRA21-1 levels, and tumor size demonstrates superior predictive capability compared to any individual factor. Conclusion Tumor location of central-type, poorly differentiated tumors, CYFRA21-1 levels, and tumor size are risk factors for lymph node metastasis in cT1N0M0 stage lung squamous cell carcinoma. The combined predictive model has certain guiding significance for intraoperative lymph node resection strategies in cT1N0M0 stage lung squamous cell carcinoma.
ObjectiveThe risk factors of relapse in 133 epileptic children after withdrawal were analyzed retrospectively and provide reference for clinical withdrawal.MethodsFrom January 2017 to March 2019, 133 children with withdrawal epilepsy were selected as the study object. According to whether there was recurrence during the follow-up period, the children with epilepsy were divided into recurrence group (42 cases) and non recurrence group (91 cases). The gender, age of onset, history of trauma, frequency of seizure before treatment, EEG before drug reduction, imaging, type of medication, family history, time of reaching control, course of disease before treatment, comorbidity, multiple attack types, withdrawal speed and EEG before treatment were observed and compared between the two groups. ResultsThere were significant differences in EEG (χ2 =7.621), medication type (χ2=8.760), time to control (χ2=6.618), course before treatment (χ2=6.435), multiple seizure types (χ2=5.443) and epilepsy comorbidity (χ2=42.795) between the two groups (P < 0.05). The results of Logistic multiple regression analysis showed that the recurrence of epileptic children after drug reduction / withdrawal was correlated with abnormal EEG before drug reduction [OR=9.268, 95%CI (2.255, 38.092)], combined drug treatment [OR=3.205, 95%CI (1.159, 8.866)] and course of disease > 1 year before treatment [OR=5.363, 95%CI (1.781, 16.150)] (P < 0.05).ConclusionsIn order to reduce the possibility of recurrence of epileptic children, the treatment time of epileptic children with abnormal EEG, combined medication and long course before treatment should be prolonged properly.
Objective To explore the clinical and inflammatory characteristics and risk factors of severe asthma to improve clinicians' awareness of the disease. Methods The general information of patients with asthma who visited the Department of Respiratory Medicine, the First Hospital of Shanxi Medical University from May 2018 to May 2021, as well as the diagnosis and treatment of asthma, personal history, comorbidities, auxiliary examination, asthma control test (ACT) score were collected. A total of 127 patients were included, including 40 in the severe asthma group and 87 in the mild-to-moderate asthma group. Chi-square test, independent sample t test and logistic regression were used to analyze the clinical characteristics, inflammatory markers and risk factors of severe asthma. Results Compared with the patients with mild to moderate asthma, the patients with severe asthma were more older (51.0±12.0 years vs 40.7±12.8 years, P<0.05), had more smokers (32.5% vs. 14.9%, P<0.05), and more males (67.5% vs. 40.2%, P<0.05). The patients with severe asthma got poor FEV1%pred [(56.1±23.8)% vs. (93.2±18.0)%, P<0.05] and FEV1/FVC [(56.7±13.2)% vs. (75.8±9.0)%, P<0.05)], and more exacerbations in the previous year (2.7±3.1 vs. 0.1±0.4, P<0.05), lower ACT score (14.4±3.7 vs. 18.0±5.0, P<0.05), and higher blood and induced sputum eosinophil counts [(0.54±0.44)×109/L vs. (0.27±0.32)×109/L, P<0.05; (25.9±24.2)% vs. (9.8±17.5)%, P<0.05]. There was no significant difference in the proportion of neutrophils in the induced sputum or FeNO between the two groups (P>0.05). Analysis of related risk factors showed that smoking (OR=2.740, 95%CI 1.053 - 7.130), combined with allergic rhinitis (OR=14.388, 95%CI 1.486 - 139.296) and gastroesophageal reflux (OR=2.514, 95%CI 1.105 - 5.724) were risk factors for severe asthma. Conclusions Compared with patients with mild to moderate asthma, patients with severe asthma are characterized by poor lung function, more exacerbations, and a dominant eosinophil inflammatory phenotype, which is still poorly controlled even with higher level of treatment. Risk factors include smoking, allergic rhinitis, and gastroesophageal reflux, etc.
ObjectiveTo explore the morbidity rate and risk factors of proliferative diabetic retinopathy (PDR) in type 2 diabetes.MethodsThe clinical data of patients, with PDR in 2739 consecutive cases of type 2 diabetes diagnosed in this hospital from 1994 to 2001 were analyed retospectively. The diagnosis of diabetic retinopathy (DR) was confirmed by ophthalmoscopy and fundus fluorescein angiography (FFA). Blood pressure, fasting and postprandial blood sugar, glycosylated haemoglobin（HbA1c）, total serum cholesterol, triglyceride, creatinine, and albumin excretion rate were measured.ResultsThe morbidity rate of type 2 DR was 27.8%（761/2739）, and the morbidity rate of PDR was 4.2%（114/2 739） occupying 15% of the patients with DR. The duration, fasting blood sugar, glycosylated haemoglobin, blood pressure and albumin excretion rate were much higher than those in the control（P＜0.01, glycosylated haemoglobin P＜0.05）. The independent risk factors of PDR were duration of the disease （r=0.15, P＜0.01） and albumin excretion rate （r=0.08, P＜0.05）. The risk factors of PDR were albumin excretion rate and fasting blood sugar (r=0.13, P＜0.05) in patients with longer duration(≥5 years). The morbidity rate of PDR was 2.3%, 5.9% and 12.4% in patients with duration less than 5 years, 5 to 10 years and over 10 years groups, respectively. The morbidity of PDR of the patients in normal albuminuria, microalbuminuria and overt albuminuria group was 2.1%、5.3% and 18.8% respectively.ConclusionsType 2 diabetes accompanied with PDR is relative to the duration of the diabetes, albumin excretion rate, fasting blood sugar, blood pressure, and glycosylated haemoglobin, in which the duration of the disease, albuminuria and fasting blood sugar are the risk factors of occurance of PDR.

ObjectiveTo explorer the risk factors for acute exacerbation in patients with bronchiectasis within one year.MethodsFour hundred and twenty-two patients with non-cystic fibrosis bronchiectasis hospitalized were enrolled in The East Region of the People’s hospital of Sichuan between October 2014 and October 2016. The patients’ clinical data were collected, and follow-up began at the time of discharged. The study endpoint was the first acute exacerbation, all patients were followed-up for one year after discharged. The patients were classified into two groups by the occurrence of acute exacerbation or no occurrence. Logistic regression analysis was used to explore the risk factors for acute exacerbation with bronchiectasis.ResultsThe age, sick time, body mass index (BMI) less than 18.5 kg/m2, smoking index, expectoration, hemoptysis, dyspnea, moist sounds, wheezing sounds, types of imaging, CT scores, lung lesion site, sputum culture, whether infected Pseudomonas aeruginosa, level of serum C-reactive protein (CRP), level of serum PCT, serum albumin, arterial carbon dioxide partial pressure, types of respiratory failure, combined with chronic cor pulmonale differed significantly between the two groups (P<0.05), while gender, history of Infection, smoking, cough, chest pain, fever, clubbed-finger, white blood cell counts, neutrophil counts, erythrocyte sedimentation rate, serum globulins, arterial oxygen partial pressure did not significantly differ (P>0.05). Multivariate Logistic regression analysis found that infection with Pseudomonas aeruginosa, BMI<18.5 kg/m2, high level of serum CRP, high level of arterial carbon dioxide partial pressure (PaCO2), high CT score with bronchiectasis, combination with chronic cor pulmonale were risk factors for acute exacerbation in patients with bronchiectasis (P<0.05).ConclusionsInfection with pseudomonas aeruginosa, BMI < 18.5 kg/m2, high serum CRP level, high arterial blood PaCO2 level, high CT score with bronchiectasis and combination of chronic cor pulmonale are risk factors for acute aggravation within 1 year for patients with bronchiectasis. Doctors can identify these risk factors and intervene early, so as to reduce the acute exacerbation of bronchiectasis.
Objective To assess the prevalence of malnutrition in patients with advanced non-small cell lung cancer (NSCLC) using the Global Leadership Initiative on Malnutrition (GLIM) criteria, analyze its associated factors, and explore the adverse effects of malnutrition on advanced NSCLC patients in multiple aspects. Methods Patients with NSCLC who were hospitalized for the first time in the Department of Oncology, Shangjin Hospital, West China Hospital, Sichuan University between January and December 2021 were retrospectively selected as the study objects. Malnutrition assessment was carried out in all patients according to GLIM criteria, and the current situation and related factors of malnutrition were analyzed. The Barthel index scale was used to compare the daily activity ability between the malnourished group and the non-malnourished group, the Quality-of-Life Questionnaire-Core 30 scale was used to compare the quality of life between the two groups, and the adverse reactions of the two groups were compared by the hospital information system course records. Results According to GLIM diagnostic criteria, 134 of 285 patients (47.0%) were diagnosed with malnutrition. The results of binary multiple logistic regression analysis showed that age [60-69 vs. <60 years old: odds ratio (OR)=2.323, 95% confidence interval (CI) (1.277, 4.397); ≥70 vs. <60 years old: OR=10.816, 95%CI (4.185, 27.959)], previous medical history [OR=2.740, 95%CI (1.313, 5.717)], and albumin level [OR=0.905, 95%CI (0.848, 0.965)] were associated with malnutrition in patients with advanced NSCLC (P<0.05). The daily activity ability and quality of life in the malnourished group were significantly worse than those in the non-malnourished group (87.57±12.48 vs. 91.82±6.77, P<0.05; 76.22±11.52 vs. 83.96±9.75, P<0.05), and the incidence of adverse reactions in the malnourished group was higher than that of the non-malnourished group (50.7% vs. 31.8%, P<0.05). Conclusions The prevalence of malnutrition in patients with advanced NSCLC is high, and advanced age, previous medical history and albumin are related factors of malnutrition in patients with advanced NSCLC. Combined malnutrition may have adverse effects on mobility, quality of life and adverse effects of anti-tumor therapy in advanced NSCLC patients.
ObjectiveTo observe the expression of connective tissue growth factor (CTGF) in injured model of retinal pigment epithelial (RPE) cells and the promoting effect of CTGF on migration of RPE cells.MethodsCultured monolayer-confluent human RPE cells were scraped with a trephine and a cotton stick, and set up the injured model of RPE cells with round scraped area. Immunohistochemistry and in situ hybridization(ISH) were used to detect the expression of CTGF protein and mRNA in injured RPE cells at distinct time points after injury. The number of RPE cells migrated to injured area was measured and the effect of CTGF on migration of RPE cells and the effect of dexamethasone (DEX) on the promoting process of CTGF were observed.ResultsThe results of immunohstochemistry and ISH indicated the weak positive expression of CTGF in RPE cells at the edge of scrape 6 hours after injury, and the positive expression increased gradually as time goes by after the injury. Strong positive expression of CTGF in RPE cells at the edge of scrape was found 24 and 48 hours after injury. Rebuilt human CTGF stimulated migration of RPE cells in a dose-depended manner, and DEX significantly inhabited the migration.ConclusionCTGF involves in the procedure of repair of injury of RPE cells, which may play an important role in the pathogenesis of intraocular proliferative diseases such as proliferative vitreoretinaopathy.(Chin J Ocul Fundus Dis, 2005,21:306-309)
ObjectiveTo systematically review the predictive factors of new-onset conduction abnormalities(NOCAs) after transcatheter aortic valve replacement (TAVR) in bicuspid aortic valve (BAV) patients. MethodsThe CNKI, VIP, WanFang Data, PubMed, Cochrane Library and EMbase databases were electronically searched to collect the relevant studies on NOCAs after TAVR in patients with BAV from inception to December 5, 2022. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 software. ResultsSix studies involving 758 patients with BAV were included. The results of the meta-analysis showed that age (MD=−1.48, 95%CI −2.73 to −0.23, P=0.02), chronic kidney disease (OR=0.14, 95%CI 0.06 to 0.34, P<0.01), preoperative left bundle branch block (LBBB) (OR=2.84, 95%CI 1.11 to 7.23, P=0.03), membranous septum length (MSL) (MD=0.93, 95%CI 0.05 to 1.80, P=0.04), implantation depth (ID) (MD=−2.06, 95%CI −2.96 to −1.16, P<0.01), the difference between MSL and ID (MD=3.05, 95%CI 1.92 to 4.18, P<0.01), and ID>MSL (OR=0.27, 95%CI 0.15 to 0.49, P<0.01) could be used as predictors of NOCAs. ConclusionCurrent evidence shows that age, chronic kidney disease, LBBB, MS, ID, the difference between MSL and ID, and ID>MSL could be used as predictors of NOCAs. Due to the limited quantity and quality of included studies, more high-quality studies are required to verify the above conclusion.
ObjectiveTo investigate the health literacy level and its influencing factors among follow-up patients with chronic kidney disease (CKD).MethodsFrom March to August 2018, 248 patients from the CKD Follow-up Management Center, West China Hospital, Sichuan University were included. Basic information questionnaire and chronic diseases health literacy scale were used. Analysis of variance and t test were used in univariate analysis, and multiple linear stepwise regression was used in multivariate analysis, to explore the influencing factors of health literacy score.ResultsThe average health literacy score of the 248 CKD patients (97.24±12.22) were in medium to low level. Listed from high to low, the score of each dimension was: ability to obtain information (4.24±0.50), willingness to improve health (4.17±0.66), competence to communicate and interact with others (3.95±0.59), and willingness to support financially (3.41±1.10). The result of multiple linear stepwise regression showed that whether followed up on time, families’ monthly income per capita, and the patients’ age were independent influencing factors of health literacy score (P<0.05).ConclusionsThe health literacy level of follow-up patients with CKD remains to be improved. Medical personnel should pay attention to whether patients with CKD are followed up on time, make targeted intervention, and improve the self-management of patients so as to delay the disease progress of CKD.
