Resumen Antecedentes: El diagnóstico de apendicitis aguda representa un reto en pacientes pediátricos. Objetivo: Establecer la importancia del índice neutrófilos-linfocitos (INL), índice plaquetas-linfocitos (IPL) y otros parámetros hematológicos ajustados por edad y sexo en la predicción de apendicitis aguda, así como describir un nuevo sistema de calificación. Material y métodos: Se analizaron retrospectivamente expedientes clínicos de 946 niños hospitalizados por apendicitis aguda. Se desarrolló un sistema de calificación basado en INL, IPL, ILM y proteína C reactiva (PCR) ajustados por edad y sexo. Resultados: Los pacientes se dividieron en grupo I de exploración negativa y grupo II de apendicitis aguda; las medias de edad correspondientes fueron 12.20 ± 2.31 y 11.56 ± 3.11. El recuento leucocitario, porcentaje de neutrófilos, INL, IPL, ILM y PCR fueron superiores en el grupo II. La calificación osciló entre 0 y 8 puntos; se determinó que 4.5 fue el mejor punto de corte para apendicitis aguda con mayor área bajo la curva (0.96), sensibilidad (94 %), especificidad (86 %), valor predictivo positivo (97.5 %), valor predictivo negativo (65 %), precisión (92.6 %) y tasa de clasificación errónea (7.4 %). Conclusión: El sistema de calificación que se propone, calculado por edad y sexo de los pacientes, se puede utilizar para evitar cirugías innecesarias.

Abstract Background: Acute appendicitis diagnosis can sometimes be a real challenge in pediatric patients. Objective: To establish the importance of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and other hematological parameters adjusted for age and sex in the prediction of acute appendicitis, as well as to describe a new scoring system. Material and methods: Medical records of 946 children hospitalized for acute appendicitis were retrospectively analyzed. A scoring system based on NLR, PLR, lymphocyte/monocyte ratio (LMR), and C-reactive protein (CRP) adjusted for age and sex was developed. Results: Patients were divided into group I, with negative examination, and group II, with acute appendicitis; mean ages were 12.20 ± 2.31 and 11.56 ± 3.11, respectively. Leukocyte count, neutrophil percentage, NLR, PLR, LMR and PCR were higher in group II. The scores ranged from 0 to 8 points; 4.5 was determined to be the best cut-off point for acute appendicitis with the highest area under the curve (0.96), sensitivity (94%), specificity (86%), positive predictive value (97.5%), negative predictive value (65%), accuracy (92.6%) and misclassification rate (7.4%). Conclusion: The proposed scoring system, calculated based on patient age and gender, can be used for unnecessary surgeries to be avoided.

Construction and efficacy evaluation of a scoring system for predicting major adverse cardiovascular and cerebrovascular events within 1 year in elderly patients with acute coronary syndrome / 中华急诊医学杂志

Objective:To establish a prediction model for major adverse cardiovascular and cerebrovascular events (MACCE) in elderly patients with emergency acute coronary syndrome (ACS) within 1 year, and to evaluate its prediction efficiency.Methods:This was a prospective cohort study. Elderly ACS patients who were admitted to the Cardiovascular Care Unit (CCU) or the Emergency Intensive Care Unit (EICU) in Beijing Bo'Ai Hospital through emergency department from January 2019 to December 2021 were successively enrolled. General data of the patients were collected within 24 h after admission, the incidence of malignant arrhythmia, complete revascularization and acute kidney injury (AKI) during hospitalization were recorded. Within 24 h, laboratory indexes such as serum creatinine (Scr), albumin (Alb), hypersensitive C-reactive protein (hs-CRP), creatine kinase isoenzyme MB (CK-MB), D-dimer, cardiac troponin I (cTnI) and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) were measured. In addition, transthoracic echocardiography and the Frailty Screening Questionnaire (FSQ) were performed. Patients were followed up for the occurrence of MACCE within 1 year. The influencing factors of MACCE were screened by univariable and multivariable logistic regression analysis. The cut-off values of continuous variables were determined by receiver operating characteristic (ROC) curve and discretization was carried out with reference to clinical practice. Corresponding scores were set up according to the β regression coefficient of each variable to establish a clinical prediction score scale of MACCE. Finally, ROC curve was used to evaluate its prediction efficiency.Results:The study enrolled 322 elderly ACS patients, and the incidence of MACCE within 1 year was 24.5%. After preliminary screening of independent variables by univariable logistic regression analysis, the influencing factors of MACCE ( P<0.2) were as follows: ① Continuous indicators: age, body mass index (BMI), Alb, hs-CRP, D-dimer, NT-pro-BNP, ejection fraction (EF), Killip grade and FSQ score; ② Discrete indicators: ≥3 comorbidities, incomplete revascularization, and AKI. Multivariable logistic regression analysis after discretization of continuous indicators showed that age ≥84 years old [odds ratio ( OR)=4.351, 95% confidence interval (95% CI): 1.635-11.576, P=0.003], incomplete revascularization ( OR=6.580, 95% CI: 2.397-18.060, P < 0.001), combined with AKI ( OR=2.647, 95% CI: 1.085-6.457, P=0.032), EF ≤50% ( OR=2.742, 95% CI: 1.062-7.084, P=0.037), and FSQ≥3 points ( OR=9.345, 95% CI: 3.156-27.671, P < 0.001) were independent risk factors for MACCE. The total score of the clinical prediction system for MACCE was 8 points, including age ≥84 years old (2 points), incomplete revascularization (2 points), FSQ ≥3 points (2 points), EF ≤50% (1 point), and combined with AKI (1 point). The area under ROC curve (AUC) of the scoring system for predicting MACCE was 0.891, (95% CI: 0.844-0.938, P < 0.001). The optimal cut-off value was >3 points, and the sensitivity and specificity were 0.825 and 0.792, respectively. Conclusions:The prediction score scale of MACCE has a good diagnostic efficacy and has certain guiding value for clinicians to judge the prognosis of elderly ACS patients.

Advances in predictive scoring system for intravenous immunoglobulin non-responsive Kawasaki disease / 国际儿科学杂志

Intravenous immunoglobulin(IVIG)is internationally recognized as the main treatment for Kawasaki disease(KD)in the acute phase, and its application can effectively reduce the incidence of coronary artery disease(CAL).However, in clinical practice, up to 26.8% of KD children do not respond to IVIG treatment, and their risk of CAL is higher and the degree of CAL is more severe.Early adjustment of treatment, such as early combined use of glucocorticoids, may play an important role in improving the prognosis and shortening the course of IVIG non-responsive KD.Therefore, early identification of IVIG non-response KD is of great significance to clinicians.In the past 20 years, domestic and foreign scholars have successively established predictive scoring system to predict the possibility of IVIG non-response in children with KD and optimize the early treatment.This article reviews the domestic and foreign research on the score system for predicting IVIG non-response in KD, in order to provide reference for clinical diagnosis and treatment.

Study on the ideal sagittal position of the lower third of the face in high-angle patients with different forehead forms / 口腔疾病防治

Objective@#To explore the ideal sagittal position of the lower third of the face in high-angle patients with different forehead forms and to provide a reference for clinical treatment. @*Methods@#Informed consent and portrait authorization were obtained from all patients, and the study passed the ethical review of the unit. We categorized forehead forms into four types: straight, rounded, type I angular (angled at the middle third of the forehead) and type II angular (angled at the upper third of the forehead). Profiles of high-angle patients with different forehead forms were collected. The initial position was when the facial axis point (FA point) was positioned at the goal anterior-limit line (GALL). After being silhouetted, the lower third of the face was moved forward and backward by 1 mm, 2 mm, 3 mm, and 4 mm each, plus the initial silhouetted picture, to obtain 9 images for each patient. A survey was created with these lateral profile silhouettes, and the silhouette images were ranked by 30 orthodontists and 30 laypersons. @*Results@# There were significant differences in profile scores at different movement distances of the lower third of the face among high-angle patients with different forehead shapes (P<0.05). Overall, high-angle patients with straight or type II angular foreheads had higher scores when the lower third of the face did not move. For high-angle patients with a rounded forehead, orthodontists and laypersons gave the highest scores when the lower third of the face was moved backward by 2 mm and 4 mm, respectively. For high-angle patients with a type I angular forehead, orthodontists thought the scores of backward movement of 4 mm were the highest, and laypersons thought the scores of backward movement of 3 mm were the highest. No significant difference was found in scores between orthodontists and laypersons (P>0.05). @*Conclusion @#The forehead forms and the sagittal position of the lower third of the face will affect the face’s profile aesthetics. Patients with straight and type Ⅱ angular foreheads has the best profile when the FA point is located on the GALL line. For patients with rounded and type Ⅰ angular foreheads, a posterior location of the lower third of the face is more desirable than the initial position.

Research progress on the histological scoring system for nonalcoholic fatty liver disease / 中华肝脏病杂志

Non-alcoholic fatty liver disease (NAFLD) has replaced chronic hepatitis B as the most common chronic liver disease in China and has now been renamed metabolic dysfunction-associated fatty liver disease (MAFLD). The Brunt, the American NASH Clinical Research Network (NASH-CRN), the European Steatosis, Activity, and Fibrosis/Fatty Liver Inhibition of Progression (SAF/FLIP), and the Pediatric NAFLD are currently the four semi-quantitative grading systems for histological evaluation. This paper reviews these four scoring systems for the clinical selection of appropriate systems for diagnosis and prognosis assessment. This article is a review, and in order to coordinate the evaluation criteria of various scoring systems, the old name "NAFLD" is used.

Clinical characteristics of dry eye in patients with type 2 diabetic peripheral neuropathy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To investigate the clinical features of dry eye in patients with type 2 diabetes mellitus complicated with peripheral neuropathy.METHOD: Prospective cohort study. A total of 192 patients with type 2 diabetes were enrolled in the Department of Endocrinology, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from July 2021 to March 2022. The right eyes of all patients were selected as the observation eye, among which 122 patients were diagnosed with diabetic peripheral neuropathy(DPN)and 70 patients were diagnosed with non-diabetic peripheral neuropathy(NDPN). The score of ocular surface disease index(OSDI), tear meniscus height, tear meniscus width, corneal epithelial thickness, corneal endothelial cell density, tear secretion test(Schirmer Ⅰ test, SⅠt), corneal sensitivity, meibomian gland function status score, tear film breakup time(BUT), corneal fluorescein sodium staining score and Toronto clinical scoring system(TCSS)score were compared between two groups. The correlation between OSDI score and TCSS score in type 2 diabetes patients was analyzed as well.RESULTS: The morbidity of dry eye in the DPN group(55 eyes, 45.1%)was significantly higher than that of NDPN group(20 eyes, 28.6%; χ2=5.094, P=0.024), BUT and corneal sensitivity score of DPN were lower than NDPN group(P&#x003C;0.001), meanwhile, corneal staining score and meibomian gland function score were higher than NDPN group(P&#x003C;0.001). OSDI scores of all subjects were negatively correlated with TCSS scores(rs=-0.233, P=0.002), and OSDI scores of DPN group were negatively correlated with TCSS scores(rs=-0.511, P&#x003C;0.001), but there was no significant correlation between the two scores of NDPN patients(rs=0.007, P=0.957).CONCLUSIONS: DPN patients are more likely to develop dry eye than NDPN patients. OSDI score is not an accurate evaluation index for type 2 diabetes patients, especially for DPN patients.

Advances in research on vascular assessment of lower extremity chronic total occlusion for interventional therapy / 西安交通大学学报(医学版)

Lower extremity chronic total occlusion (CTO) is the most severe manifestation of peripheral artery disease (PAD), with high amputation and mortality rates. As a minimal invasive reconstruction therapy, endovascular therapy (EVT) plays an important role in limb salvage for CTO in current clinical practice. The complexity of CTO lesions leads to a high risk for complications and a low success rate of EVT. Therefore, establishing a grading or scoring system to predict the success rate of revascularization strategy will be helpful in developing appropriate treatment strategies and assessing benefits and risks. This paper summarizes the most popular CTO scoring systems, such as PACSS grading, PARC grading, TAC grading, CTOP classification, Infrapop-CTO scoring, and J-BTK CTO scoring. PACSS grading and PARC grading are suitable for evaluating the severity of vascular calcification including iliofemoral segment, femoral-popliteal segment, and below-the-knee artery segment. TAC grading is suitable for grading calcification below the knee lesions; with low intervention success rate in a high calcification grading. CTOP classification was developed by analyzing the effect of morphological characteristics of proximal and distal fibrous caps of lower extremity CTO lesions on the outcome of EVT. The success rate of antegrade intervention is lower in type IV. The Infrapop-CTO score and J-BTK CTO score can predict successful anterograde crossing of infrapopliteal CTO lesions, with low intervention success rate in high score. Both scoring systems use three variables, namely, shape of proximal stump, calcification, and occlusion length.

Assessment of Severity of Pancreatitis by Computerized Tomography Using Revised Atlanta Classifica?on and Comparison with BISAP Clinical Scoring System

Background: Untreated acute pancrea??s can have high morbidity and mortality. It is a serious gastrointes?nal emergency. Its incidence is approximately 51.0 % and it can cause both local and systemic problems. The diagnosis usually involves laboratory tests like amylase and lipase as well as an ultrasound exam. The ideal imaging test is a contrast-enhanced CT scan. This study used scoring systems based on laboratory and radiological inves?ga?ons to determine the clinical progression and outcome. Methods : Pa?ents who were diagnosed with acute pancrea??s and in whom computed tomography was done were included. From the imaging findings, the category and subcategory of acute pancrea??s and types of fluid collec?ons were described in these pa?ents using the revised Atlanta classifica?on. BISAP score was calculated in all these pa?ents. The clinical outcome assessed in these pa?ents is the dura?on of stay in the hospital, mortality, presence of persistent organ failure, the occurrence of infec?on and need for interven?on. Finally, the correla?on between the Revised Atlanta classifica?on and BISAP score was analyzed and compared with clinical outcomes. Results: The analysis of the correla?on between Revised Atlanta classifica?on severity grade and BISAP score, among the n=57 pa?ents with mild acute pancrea??s n=56, had BISAP score less than 3 and only one had BISAP score greater or equal to three. Among the n=25 pa?ents graded as moderately severe acute pancrea??s, n=20 cases had a BISAP score of less than 3 and n=5 had BISAP score greater than or equal to three. Among the n=08 pa?ents graded as severe acute pancrea??s, n=3 had a BISAP score of less than 3 and n=5 had BISAP score greater than or equal to three. Conclusion: Standardizing nomenclature and facilita?ng proper documenta?on of a variety of imaging abnormali?es in acute pancrea??s is made possible by incorpora?ng the new Atlanta categoriza?on system into daily prac?ce. We can triage, predict, and treat pa?ents with acute pancrea??s with greater precision by integra?ng the new Atlanta classifica?on with BISAP clinical grading, significantly improving medical care.

Drug rash with eosinophilia and systemic symptoms syndrome in an elderly man on carbamazepine � A jeopardising clinical entity

Drug rash with eosinophilia and systemic symptoms syndrome (DRESS) is a rare but serious hypersensitivity drug reaction most frequently associated with antiepileptics. We report a case of carbamazepine-induced DRESS syndrome in a 61-year-old man who was recently initiated on carbamazepine (6 weeks back) and presented with a history of acute febrile illness of 10 days duration. General examination showed multiple erythematous coalescent papules and rash over the body with relative sparing of the face with lymphadenopathy. Laboratory results revealed eosinophilia, atypical lymphocytosis, transaminitis, and negative serology for hepatitis. Registry of severe cutaneous adverse reactions (RegiSCAR) scoring system case is categorized as a definite case with a score of 7. Carbamazepine was discontinued and with the initiation of intravenous steroids; the transaminitis improved, fever and rashes resolved.

Clinical differentiation of Pythium keratitis from fungal keratitis and development of a scoring system

Purpose: To differentiate Pythium keratitis from fungal keratitis using clinical signs, to explore usefulness of various signs as diagnostic prognosticators, and develop a clinical scoring system. Methods: A retrospective review of medical records and archived clinical photographs of patients with culture?positive Pythium keratitis and hyaline filamentous fungal keratitis was conducted at a tertiary eye institute to explore characteristics of ulcers that may aid diagnosis. Results: Full?thickness corneal stromal keratitis (P = 0.055), a dry ulcer surface (P = 0.010), tentacles (P < 0.0001), intrastromal dots (P < 0.0001), ring infiltrates (P = 0.024), reticular patterns (P < 0.0001), and peripheral furrows (P < 0.0001) were clinical signs associated with Pythium keratitis. Multiple regression analysis identified tentacles (odds ratio: 24.1, 95% confidence interval (CI): 3.8–158.1, P = 0.001) and peripheral furrows (odds ratio: 60.6, 95% CI: 5.1–712.3, P = 0.001) as independent diagnostic prognosticators for Pythium keratitis. The positive and negative likelihood ratios of a dry ulcer surface, tentacles, intrastromal dots, ring infiltrates, reticular patterns, and peripheral furrows predicting Pythium keratitis were 1.6, 13.6, 17.9, 4.3, 30.7, 15.3 and 0.4, 0.4, 0.7, 0.9, 0.6 and 0.8, respectively. The presence of two or more of these clinical signs (excluding a dry ulcer surface) had a sensitivity of 55.6% and a false positive rate of 1.4%. Conclusion: Tentacles, intrastromal dots, ring infiltrates, reticular patterns, and peripheral furrows are clinical signs to be considered for the diagnosis of Pythium keratitis and the presence of two or more signs has a very low false positive rate

Research status and prospect of cardiac arrest early warning scoring system / 中华危重病急救医学

Cardiac arrest is the fourth stage of sudden cardiac death, which is characterized by the cessation of electrical activity in the heart, rapid circulatory and respiratory failure, and the prognosis is often poor. How to effectively predict cardiac arrest is the key and difficult point in the diagnosis and treatment process. In recent years, the research on the application of early warning scoring system in cardiac arrest has made continuous breakthroughs, from initially formulating a traditional scoring system containing only basic vital signs indicators according to a certain number of samples to continuously increasing and changing indicators, increasing the sample size, and formulating an improved scoring system with better sensitivity and specificity. Nowadays, with the continuous development of electronic information technology, machine learning technology is introduced into the formulation of scoring system, which breaks through the limitations of previous scoring system and has achieved good results in clinic. This article analyzes and compares the relevant research and cutting-edge progress of different early warning scoring systems at home and abroad, and summarizes the research results, gaps and shortcomings. Finally, combined with the relevant policies of graded diagnosis and treatment in China, this paper discusses the development and application direction of cardiac arrest early warning scoring system in the future.

Effect of intelligent early warning scoring system in condition monitoring of hospitalized non-critically ill patients / 中华急诊医学杂志

Objective:To establish and apply the electronic further modified early warning score system (e-fMEWS), and explore its role in the condition evaluation and early warning of inpatients in non-critical units, so as to provide clinical nurses with an early and dynamic method to identify the potential deterioration risk of patients' condition.Methods:A retrospective analysis of 262 805 inpatients in multiple non-critical units of the Second Affiliated Hospital of Zhejiang University School of Medicine from January to December 2018 and January to December 2020 was performed. The patients who were hospitalized from January to December 2018 were used as the control group, and the responsible nurse used the traditional single evaluation index to start the emergency response system; the patients from January to December 2020 were used as the research group, and the emergency response system was started using e-fMEWS. The inclusion criteria were as follows: (1) hospitalization time ≥24 h; (2) patient ≥14 years old. Exclusion criteria were as follows: (1) patients had cardiopulmonary resuscitation before admission; (2) patients discontinued treatment or were transferred to another hospital during treatment; (3) patients received palliative care; (4) patients were admitted to non-critical wards in grade I of emergency pre-examination and triage. The activation of the rapid response team (RRT), the activation of the cardiorespiratory arrest team, the incidence of cardiac and respiratory arrest, the number of cases of invasive mechanical ventilation, the number of cases admitted to the intensive care unit, the length of hospital stay and the prognosis were compared. Statistical software SPSS 22.0 was used for data analysis.Results:Under the e-fMEWS assessment, compared with the control group, the rate of initiation of the research group decreased by 0.03%. For patients who initiated RRT, the average length of hospital stay was shortened, and the number of in-hospital respiratory cardiac arrest decreased (12.2% vs. 13.2%) and the number of cases transferred to the intensive care unit was less (42.8% vs. 50.6%), the rate of improvement and recovary increased (58.4% vs. 56.1%).Conclusions:The application of e-fMEWS can help clinical nurses to quickly and accurately identify the potential risk of deterioration of the patient's condition. Through early identification of potentially critically ill patients in non-critical units, early intervention and timely treatment can avoid adverse events and improve the patient prognosis.

Progress in the application of critically ill neonatal transport score / 国际儿科学杂志

Emergency transport of critically ill neonates is an important means to reduce neonatal mortality and improve prognosis.Neonatal transport score is used to evaluate the safety of transport, mainly including transport risk index of physiologic stability, mortality index for neonatal transportation, transport related mortality score and intrauterine transport score.Evaluating the severity of disease of critically ill newborns before, during and after transport can reduce the occurrence of transport complications, reduce neonatal mortality, improve prognosis and increase the success rate of treatment.This paper reviews the research progress of critical neonatal transport scoring at home and abroad to help clinicians choose appropriate scoring methods according to specific conditions, in order to provide a basis for continuous quality improvement in this field.

Constructing a trauma scoring system from databases of road crash patients in Philippine Hospitals (2009–2019)

Introduction@#Trauma scoring standardizes the severity of injuries of patients brought to trauma centers and is predictive of the outcome or prognosis among trauma victims. Hence, creating a trauma score allows for proper prioritization as well as proper management of patients in the emergency departments. @*Objectives@#The objective of the study is to come up with a trauma scoring system that correlates to the probability of survival of a patient using the patient databases in major hospitals in the Philippines representing the three major island groups, Luzon, Visayas, and Mindanao. The study will also compare this proposed trauma scoring system with the gold standard (Revised Trauma Score) developed by Champion in 1989. @*Methods@#The proposed Philippine Trauma Scoring System (PTSS) was based on data from the eight largest tertiary hospitals catering to trauma patients. A total of 40,286 patient charts were reviewed. The proposed trauma scoring system integrates concepts used in the Revised Trauma Score (RTS), with addition of age (from Kampala Trauma Scoring), as well as the Injury Score (based on the number of body parts injured). This proposed scoring system was weighted, using logistic regression to come up with coefficients for the components of the PTSS for a more accurate prediction of patient survival. The Receiver Operating Characteristic (ROC) was used to plot Sensitivity vs. 1-Specificity. In this analysis, ROC was used to evaluate and compare how good the models are in predicting patient recovery.@*Results@#The components of GCS, RR, SBP, age, and body parts injured were significant predictors of patient outcomes for patients with trauma, specifically the road crash patients in this Philippine study. This study showed that both the PTSS and RTS have a significantly greater area under the curve than the diagonal reference line, which means that both the scoring system have a significant predictive value. The best predictive value, however, comes from the proposed scoring system that is developed from this study in the Philippines. Compared to the gold standard, PTSS Model 1 is a better predictor of outcomes than the gold standard RTS (ROC-AUC = 0.659 vs. 0.633) using only 22,214 valid subject population that contained all the variables needed for the PTSS analysis. @*Conclusion@#In a developing country like the Philippines, there are limited resources especially in the healthcare setting. Therefore, it is important to lessen errors in triaging which may result in resource waste and a higher risk of adverse outcomes for the patients. Thus, the PTSS developed in this study can be used by Philippine hospitals as it is uniquely based on Filipino patients using a large database representative of the eight largest tertiary hospitals in the Philippines. The proposed PTSS is shown in this study as the best classifier for patient outcome compared to the gold standard – RTS of Champion.

Study on the effectiveness of the proportion of inflammatory cells in the lamina propria of intestinal mucosa in predicting mucosal histological healing in patients with ulcerative colitis / 中华消化杂志

Objective:To determine a simpler and more practical scoring standard for predicting mucosal histological healing in ulcerative colitis (UC).Methods:From April 11, 2017 to February 8, 2021, 68 UC patients diagnosed with mucosal healing under endoscopy and hospitalized at Department of Gastroenterology, the Tenth People′s Hospital of Tongji University and during the same period 60 healthy individuals who underwent endoscopy for health checkup were retrospectively analyzed. Modified Mayo score and ulcerative colitis endoscopic index of severity (UCEIS), the modified Nancy index and Robarts histopathology index were determined based on the collected clinical data, endoscopic reports and histopathological evaluation. The proportions of neutrophils, eosinophils, and plasma cells in the colonic mucosal lamina propria were calculated. The proportions of activated neutrophils and T cells in the colonic mucosal lamina were calculated according to CD177 and CD40L, respectively. The new clinical and laboratory diagnostic formulas were determined by multivariate logistic regression analysis, the effectiveness of the equations was evaluated by receiver operating characteristic curve (ROC).Results:Among the 68 patients with UC, the modified Mayo score was 0.7 (0.4, 1.1), the UCEIS was 0.5 (0.3, 0.8), the Nancy index was 5.9±3.2, and the Robarts histopathology index was 2.6±1.7. According to multivariate logistic regression analysis, the formula for clinical diagnosis of histological healing was Y1=-21.09+ 355.9 X1+ 305.8 X2+ 44.91 X3 ( X1, X2 and X3 were the proportions of neutrophils, eosinophils, and plasma cells, respectively). The results of ROC analysis indicated that Y1<-0.747 was the cut-off value of diagnosis of histological healing, and the area under the curve (AUC) was 0.986 and 95% confidence interval ( CI) was 0.922 to 1.000 ( P<0.001), the sensitivity was 97.10% and the specificity was 91.20%. The formula of laboratory diagnosis of histological healing was Y2=-10.57+ 469.1 X1 + 132.7 X2 + 101.2 X3 + 18.56 X4 ( X1, X2, X3, and X4 were the proportions of CD177 + neutrophils, eosinophils, CD40L + T cells and plasma cells, respectively). The results of ROC analysis indicated that Y2<1.960 was the cut-off value of diagnosis of histological healing, and the AUC was 0.980, 95% CI was 0.913 to 0.999 ( P<0.001), the sensitivity was 84.78%, and the specificity was 100.00%. The new clinical and laboratory diagnostic criteria were positively correlated with the Nancy histological index ( r=0.411 and 0.308, P=0.001 and 0.011), and Robarts histopathology index ( r=0.311, 0.273, P=0.010 and 0.024). Conclusions:Compared with the Nancy index, the new clinical and laboratory diagnostic criteria are simpler and more practical. The new clinical diagnostic formula Y1<-0.747 and the new laboratory diagnosis formula Y2<1.960 are the independent factors for predicting histological healing in UC patients.

Evaluation of eCura scoring system for treatment strategy selection after non-curative endoscopic resection of early gastric cancer / 中华消化内镜杂志

Objective:To evaluate the adjuvant role of the eCura scoring system in selecting appropriate treatment strategies after non-curative endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) patients.Methods:The clinicopathological data of 110 EGC patients who underwent non-curative ESD at Fujian Provincial Hospital from January 2015 to June 2019 were retrospectively analyzed. According to the eCura score, patients were divided into three lymph node metastasis (LNM) risk groups: low-risk group (79 cases), middle-risk group (22 cases), and high-risk group (9 cases). The receiver operator characteristic (ROC) curve analysis was used to test the diagnostic efficacy of eCura scoring system in predicting LNM. Logistic regression analysis was used to explore the influence of risk stratification of eCura scoring system on LNM. Kaplan-Meier method was used to evaluate cancer survival rate, which was then compared with log-rank test.Results:Thirty-five patients underwent additional standard surgery after ESD, including 22 in the low-risk group, 8 in the middle-risk group, and 5 in the high-risk group. Among them, 5 cases had LNM, including 1 case in the low-risk group and the middle-risk group respectively and 3 cases in the high-risk group. The area under the ROC curve was 0.857 (95% CI: 0.697-0.952, P=0.001), and when the cut-off value of the eCura score was set at 3, the Yuden index reached the maximum value of 0.7, with the corresponding sensitivity and specificity of 80% and 90%, respectively. Logistic regression analysis showed that the probability of LNM in the middle-risk group was about 3.00 times (95% CI: 0.17-54.57, P=0.458) as high as that in the low-risk group, and the probability of LNM in the high-risk group was about 31.50 times (95% CI: 2.14-463.14, P=0.012) of that in the low-risk group. The follow-up time was 12 to 58 months, and the median follow-up time was 40 months. There were 10 cases of recurrence, including 4 cases in the low-risk group, 3 cases in the middle-risk group and 3 cases in the high-risk group, of which 2 cases in the low-risk group were from those of additional standard surgery after ESD, and the remaining 8 cases were from those who did not receive additional standard surgery after ESD. Kaplan-Meier survival curve analysis showed that the survival rate of patients with additional surgery in the low-risk group was similar to that of patients without ( P=0.319), and the survival rate of patients with additional surgery in the middle-risk group was also similar to that of patients without ( P=0.296). The survival rate of patients with additional surgery in the high-risk group was significantly higher than that of those without ( P=0.013). Conclusion:The eCura scoring system can assist the selection of treatment strategies after non-curative resection of EGC, and can accurately predict the risk of subsequent LNM and recurrence. Close follow-up may be an acceptable option for patients with low risk of LNM, and additional standard surgical treatment may be more conducive to improving the prognosis in patients with high risk of LNM.

Objective:To explore the predictive value of HEART score combined with N-terminal pro-B-type natriuretic peptides (NT-proBNP) for 3-month major adverse cardiovascular events (MACE) in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS).Methods:This was a retrospective cohort study. Adult patients with acute chest pain who met the diagnostic criteria for NSTE-ACS in the 5th Affiliated Hospital of Sun Yat-Sen University from January 2018 to March 2018 were enrolled. Patients with cardiac chest pain caused by diseases other than NSTE-ACS, non-cardiac chest pain, renal insufficiency, acute cerebral infarction, end-stage disease, pregnant, and incomplete data were excluded. Data of all patients’ general clinical information, first electrocardiogram (ECG), cardiac troponin I (cTnI), and NT-proBNP were collected. The correlation between NT-proBNP level and the occurrence of MACE within 3 months was analyzed. The receiver operating characteristic (ROC) curves was drawn, and the predictive value of NT-proBNP, HEART score, and their combination for 3- month MACE in patients with NSTE-ACS were evaluated.Results:A total of 151 patients were enrolled. Patients with NSTE-ACS were divided into the MACE group ( n=95) and non-MACE group ( n=56) according to whether MACE occurred within 3 months of onset. The level of NT-proBNP, the HEART score, and the cTnI level in the MACE group were significantly higher than those in the non-MACE group (all P<0.001). After risk stratification assessed by HEART score in all patients with NSTE-ACS, it was found that the level of NT-proBNP and the incidence of MACE increased as the risk score increased (all P<0.05). The area under the ROC curve of HEART score, NT-proBNP and their combination were 0.819 (95% CI:0.751-0.887), 0.821 (95% CI:0.752-0.889) and 0.858 (95% CI:0.796-0.919), respectively. Conclusions:The combination of HEART score and NT-proBNP level can improve the predictive value for 3-month MACE in patients within NSTE-ACS, and provide important information for treatment decision and improving prognosis.

Application of contrast-enhanced ultrasound in evaluation of donor kidney quality / 器官移植

In recent years, although the quantity of organ donation after citizen's death has been constantly increased, a large number of patients with end-stage renal diseases are waiting for kidney transplantation every year. The imbalance between donor and recipient is still one of the main problems affecting kidney transplantation in clinical practice. Therefore, it is of clinical significance to accurately evaluate the quality of donor kidney and fully utilize the expanded criteria donor kidney. Contrast-enhanced ultrasound has been gradually applied in the detection of multiple solid organs due to its safety, portability, real-time detection, quantification and other characteristics, and it also has promising application prospect in the evaluation of donor kidney quality. In this article, the advantages and limitations of current evaluation methods for donor kidney and current status and advantages of contrast-enhanced ultrasound in donor kidney evaluation were reviewed, and the application prospect of contrast-enhanced ultrasound in the evaluation of donor kidney quality was discussed, aiming to increase the methods and enhance the accuracy for donor kidney evaluation, and provide reference for rational use of expanded criteria donor kidney.

Analysis of correlation between serum homocysteine level and severity of coronary heart disease / 公共卫生与预防医学

Objective To observe the correlation and clinical significance between serum homocysteine (HCY) level and the severity of coronary heart disease (CHD). Methods A total of 497 hospital-based patients with newly diagnosed coronary heart disease from June 2018 to June 2021 in our hospital were selected as the study subjects. The patients' sociodemographic information, coronary heart disease condition information and HCY level information at diagnosis were collected. The correlation between serum HCY level and the severity of coronary heart disease was analyzed from multiple perspectives. Data were collected and analyzed using SPSS 19.0 statistical software package. Results The average level of HCY in all patients was (20.23±2.18) μmol/L, among which 330 cases exceeded the standard level of HCY and 167 cases did not exceed the standard level. There were statistically significant differences in serum HCY levels among patients with different genders, different ages, different altitudes, and different types of coronary heart disease (P<0.05). The correlation coefficients between HCY level and the severity of CHD in different genders were r1=0.356, and r2 =0.198, P<0.05. The correlation coefficients between HCY level and the severity of CHD in patients of different ages were r1=0.304, r2=0.50, r3=0.217, and r4=0.185, P<0.05. The correlation coefficients between HCY level and the severity of CHD in patients living at different altitudes were r1=0.129, r2=0.369, and r3 =0.473, P<0.05. The correlation coefficients between HCY level and the severity of CHD in patients with different types of CHD was r1=0.137, r2=0.200, and r3=0.205, P<0.05. Logistic multivariate regression analysis showed that serum HCY, altitude, gender and age were independent risk factors for coronary heart disease (P<0.05). Conclusion The correlation between serum HCY level and the severity of CHD is stronger in male patients than in female patients. The correlation between HCY level and the severity of CHD was strongest in patients aged 40-50. Serum HCY level is more strongly correlated with the severity of CHD in patients with high altitude. Serum HCY test can be used to diagnose CHD and evaluate the severity of coronary artery disease.

Effects of Leukapheresis on Hemostatic Function in Patients with Hyperleukocytic Leukemia / 中国实验血液学杂志

OBJECTIVE@#To analyze and compare the effects of leukapheresis on hemostatic function in patients with hyperleukocytic leukemia.@*METHODS@#A total of 139 patients with AML, ALL and CML who underwent leukapheresis from June 2009 to February 2020 and did coagulation test before and after operation were included in this study. The clearance efficiency of each group and the difference among three groups were evaluated, as well as hemostatic function including platelet counts, coagulation indicators, CDSS score and incidence of adverse events. The difference of hemostatic function caused by leukapheresis in different leukemia patients were compared.@*RESULTS@#After leukapheresis, the WBC counts were decreased significantly in the three groups of patients (P<0.001), and the clearance efficiency was highest in ALL patients. However, the platelet counts also were decreased significantly (AML:P＜0.001, ALL: P＜0.001, CML: P＜0.01) in the three groups of patients, particularly for acute leukemia patients with a positive correlation with WBC clearance efficiency(r=0.284). After leukapheresis, fibrinogen decreased, PT and APTT prolonged. For acute leukemia patients, higher CDSS score was related to an elevated incidence of bleeding events (P<0.05).@*CONCLUSION@#Leukapheresis is an effective method to decrease the leukemic burden, but it is necessary to monitor the impact on hemostatic function. It is recommended to assess the CDSS socre for acute leukemia patients, in order to identify the predictive value for bleedings.
