ABSTRACT
Objective@#In this research, the influence of breviscapine on anxiety, fear elimination, and aggression and the potential mechanism was investigated. @*Methods@#Anxiety and locomotion were analyzed by elevated plus maze and open field test in mice. Bussey-Saksida Mouse Touch Screen Chambers were used to perform fear conditioning. Territorial aggression was assessed by resident intruder test. Protein levels were evaluated by Western blot. Breviscapine improved fear-extinction learning in BALB/cJ mice. @*Results@#Breviscapine at 20–100 mg/kg increased center cross number, total distance traveled, and velocity in a dose-dependent manner. On the other hand, breviscapine at 20–100 mg/kg decreased the immobility time in open field test. In addition, breviscapine at 20–100 mg/kg increased the ratio of time on the open arm, time on the distal parts of the open arm, and total distance traveled in elevated plus maze. Breviscapine at 100 mg/kg increased the average attack latency and decreased the number of attacks over the last 3 days of resident intruder test. In hippocampus, protein levels of postsynaptic density protein-95 and synaptophysin were elevated by breviscapine at these three doses. @*Conclusion@#The administration of breviscapine alleviates fear extinction, anxiety, and aggression, while increases locomotor in a dose-dependent manner, which might be associated with its influence on synaptic function.
ABSTRACT
@#Objective To evaluate the effects of various polysorbates(PS)on the stability of different types of monoclonal antibody(mAb)drugs.Methods Three types of monoclonal antibodies mAbA(IgG1 proantibody drug),mAbB(IgG1 mAb)and mAbC(IgG1 mAb with Fc N297A mutation)were used as model proteins,and different kinds or contents of PS were added into the mAb formulations respectively to investigate the influencing factors.The effects of PS on the stability of mAb drugs were evaluated comprehensively by detecting the changes of quality attributes,such as protein aggregates and insoluble particles.Results PS20 and PS80 showed no significant difference in inhibiting the formation of aggregates and charge variants in the three mAbs(P>0.05),while the addition of PS80 in mAbB and PS20 in mAbC significantly inhibited the increase of insoluble particles respectively(P<0.05);The content of PS20 showed a significant effect on the detection indexes of charge variants and insoluble particles in mAbC(P<0.05).Conclusion Different types of mAbs have different sensitivities to various kinds and contents of PS.Therefore,when designing the formulation of mAbs,it is necessary to select appropriate kinds and contents of PS to further improve the stability of mAb drugs.
ABSTRACT
ObjectiveThe purpose of this study was to evaluate the functional outcomes and satisfaction in periprosthetic knee infection patients after above-the-knee amputation （AKA）. MethodsA review was performed in 13 patients who underwent AKA due to periprosthetic knee infection from October 2010 to August 2022， there were 7 females and 6 males with the median age of 69 （45~ 73） years. The mean number of surgical procedures between primary total knee arthroplasty and AKA was 2.9 times （range： 1 ~ 6）. Patients were segregated into non-elderly group （including patients <65 years old） and elderly group （involving patients ≥65 years old）. Functional outcomes were evaluated by SF-12 and Barthel activities daily living index （Barthel ADL index）. Patient satisfaction was accomplished through a questionnaire. ResultsFour patients died within 6 months after the amputation. Three patients received surgical procedures for recurrent infections after AKA. In the remaining 9 patients，the median time from AKA to the final follow-up was 4.2 （1.9~8.2） years， three patients received surgical procedures for recurrent infections after AKA. Patients in non-elderly group showed better functional outcomes than elderly patients after AKA （both P<0.05）. All patients in non-elderly group were fitted with a prosthesis. Whereas， elderly patients reported a better satisfaction after AKA than young patients. ConclusionYoung PJI patients seemed to have better function and ambulatory ability with high expectation and demand， which made them feel less satisfied about AKA. Meanwhile，despite poor function outcomes due to the less healthy physical condition， the alleviation of financial and psychological burdens resulting from reinfections and multiple surgeries and the less demand in function and daily activities made elderly patients have a good satisfaction after AKA.

ABSTRACT
Objective@# To investigate the clinical manifestations, pathological features, and treatment of oral and maxillofacial pyogenic granulomas induced by camrelizumab. @*Methods@# A case of pyogenic granuloma of the gums and lips caused by camrelizumab was reported along with a literature review. @*Results@# After 4 months of treatment with camrelizumab for liver cancer, the patient developed systemic reactive capillary hyperplasia (RCH), followed by multiple masses on the lower lip and gingiva. After periodontal therapy, the masses on the lower lip and the gingiva were removed, and camrelizumab administration was stopped. The pathological result was gingival pyogenic granuloma/granulomatous hemangioma. No new masses were found in the oral cavity during postoperative follow-up. A review of the literature showed that RCH is the most common adverse drug reaction to camrelizumab but it occurs infrequently in the oral cavity. At present, the etiology of RCH has not been clarified, but the research has shown that camrelizumab may trigger tissue proliferation into hemangiomas by activating vascular endothelial cells, and the combined use of camrelizumab is safer than single use. RCH is self-limiting and most cases resolve spontaneously after discontinuation of the drug. If the mass causes dysfunction, surgical excision is feasible.@*Conclusion @#Camrelizumab can cause oral and maxillofacial reactive capillary hyperplasia complicated by pyogenic granuloma.
ABSTRACT
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.
ABSTRACT
SUMMARY: This study aimed to compare the clinical value of carotid ultrasound and digital subtraction angiography (DSA) for carotid artery stenosis in patients with cerebral infarction. Sixty patients with cerebral infarction underwent carotid ultrasound and DSA. Carotid artery stenosis, degree of stenosis (mild, moderate, severe, and occlusion), and carotid artery plaques were recorded and compared. Carotid stenosis rate was 96.67 % (58/60) and 91.67 % (55/60) on DSA and carotid ultrasound, respectively, and the difference was not statistically significant. Mild, moderate, and severe carotid artery stenosis and occlusion were diagnosed in 35, 28, 20, and 17 arteries, respectively, with DSA, and in 39, 25, 10, and 9 arteries, respectively, with carotid ultrasound. There was a statistically significant difference in the degree of carotid stenosis between the two methods (p<0.05). The kappa value of carotid plaques detected by carotid ultrasound and DSA was 0.776, indicating good consistency. Both carotid ultrasound and DSA are effective for screening carotid artery stenosis and carotid atherosclerotic plaques. While carotid ultrasound is faster and more convenient, DSA can more accurately detect the degree of stenosis and presence of occlusion. Thus, our recommendation is a combination of carotid ultrasound and DSA in clinical settings to improve the convenience and accuracy of diagnosis.
Este estudio tuvo como objetivo comparar el valor clínico de la ecografía carotídea y la angiografía por sustracción digital (DSA) para la estenosis de la arteria carótida en pacientes con infarto cerebral. Sesenta pacientes con infarto cerebral fueron sometidos a ecografía carotídea y DSA. Se registraron y compararon la estenosis de la arteria carótida, el grado de estenosis (leve, moderada, grave y oclusión) y las placas de la arteria carótida. La tasa de estenosis carotídea fue del 96,67 % (58/60) y del 91,67 % (55/60) en DSA y ecografía carotídea, respectivamente, y la diferencia no fue estadísticamente significativa. Se diagnosticaron estenosis y oclusión de la arteria carótida leve, moderada y grave en 35, 28, 20 y 17 arterias, respectivamente, con DSA, y en 39, 25, 10 y 9 arterias, respectivamente, con ecografía carotídea. Hubo una diferencia estadísticamente significativa en el grado de estenosis carotídea entre los dos métodos (p<0,05). El valor kappa de las placas carotídeas detectadas por ecografía carotídea y DSA fue de 0,776, lo que indica una buena consistencia. Tanto la ecografía carotídea como la DSA son eficaces para detectar la estenosis de la arteria carótida y las placas ateroscleróticas carotídeas. Si bien la ecografía carotídea es más rápida y conveniente, la DSA puede detectar con mayor precisión el grado de estenosis y la presencia de oclusión. Por lo tanto, nuestra recomendación es una combinación de ecografía carotídea y DSA en entornos clínicos para mejorar la conveniencia y precisión del diagnóstico.
ABSTRACT
Objective:To study the locational distribution characteristics of the heterotopic ossification (HO) following traumatic elbow stiffness and the risk factors for HO development at different locations.Methods:Consecutively included according to our inclusion criteria in the present study were the patients who had been admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from January 2018 to December 2018 for elbow release due to traumatic elbow stiffness but developed postoperative HO. Their baseline data and CT data were collected and processed using Mimics 20.0. The HO distribution for each patient was characterized at the anteromedial, anterolateral, posteromedial, posterolateral, posterior, medial, lateral, and proximal radioulnar locations. The patient's original injury was categorized into 5 types: distal humerus fracture, olecranon fracture, radial head fracture, coronoid fracture, and elbow dislocation. After the univariate analysis with the HO occurrence at a specific location as the dependent variable and the original injury and baseline data as the independent variables, the factors with P value less than 0.1 were included in the logistic regression analysis to determine the risk factors for HO at each location.Results:A total of 91 patients were included in this study. Of them, 88 had posteromedial HO (96.7%, 88/91), 62 posterior HO (68.1%, 62/91), 60 posterolateral HO (65.9%, 60/91), 41 anteromedial HO (45.1%, 41/91), 26 anterolateral HO (28.6%, 26/91), 13 proximal radioulnar HO (14.3%, 13/91), 8 lateral HO (8.8%, 8/91), and 7 medial HO (7.7%, 7/91). Logistic regression analysis showed that presence of ulnar nerve symptoms ( OR=4.354, P=0.017) and presence of original elbow dislocation ( OR=2.927, P=0.042) were the independent risk factors for the anteromedial HO development and that presence of original olecranon fracture ( OR=0.277, P=0.023) was the protective factor for the anteromedial HO development. Presence of original radial head fracture was the independent risk factor for the anterolateral HO development ( OR=2.891, P=0.033) and the posterolateral HO development ( OR=3.123, P=0.043). Conclusions:HO development in patients with post-traumatic elbow stiffness is closely related to their original injury. Posteromedial HO may develop in almost all the patients. Patients with ulnar nerve symptoms and original elbow dislocation are more prone to anteromedial HO development, but patients with original olecranon fracture are less likely to develop anteromedial HO. Patients with original radial head fracture are more likely to develop anterolateral and posterolateral HO.
ABSTRACT
Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
ABSTRACT
Objective:To explore the diagnosis, treatment and prevention of biliary hemorrhage after percutaneous transhepatic choledochoscopic lithotomy(PTCSL).Methods:Retrospective summary and analysis were made on 48 cases of PTCSL completed by the hepatobiliary surgery department of Hunan Provincial People′s Hospital (the First Affiliated Hospital of Hunan Normal University) from January 2016 to December 2020.Results:Biliary hemorrhage occurred in 3 cases after operation, of which 1 case was considered to have a small amount of biliary mucosa bleeding, and the bleeding was stopped after blood transfusion, hemostatic agents and appropriate fluid rehydration. In the other case, a small amount of blood oozing around the T-tube sinus canal was accompanied by a small amount of bloody fluid in the T-tube, which was considered to cause arterioles or venules accompanied by bile duct bleeding during sinus expansion during operation, and the bleeding stopped after compression. Another patient underwent a short time drainage of hemorrhagic fluid ≥100 ml in T tube 15 days after operation, and was prepared for interventional therapy while receiving blood transfusion products and conservative treatment. Celiac arteriography was performed, and pseudoaneurysm was found in the right anterior lobe of the liver. Embolization was performed later and the patient discharged 10 days after embolization.Conclusions:Biliary hemorrhage is one of the more common complications after PTCSL. Increasing the understanding of this complication provides a guarantee for the safety of surgery and has clinical significance for patients with accelerated postoperative recovery.
ABSTRACT
Objective:The aims of the study were to investigate the relationship among atherogenic index of plasma (AIP) and inflammatory adipocytokines with the severity of coronary artery calcification (CAC) score in coronary artery disease (CAD). And then we analyzed the diagnostic value of the new markers on CAC.Methods:A total of 241 patients with CAD diagnosed by coronary CT angiography (CTA) and coronary angiography in Baoding First Central Hospital from June 2019 to June 2020 were retrospectively enrolled. According to the presence of calcification in coronary CTA, they were divided into CAC group ( n=63) and non-CAC group ( n=178). The clinical data of the patients were collected, and the levels of serum inflammatory factors were measured by enzyme-linked immunosorbent assay (ELISA). The correlation between CAC score and AIP and inflammatory cytokines was analyzed. The diagnostic value of AIP and inflammatory factors in the formation of CAC in patients with CAD. Results:The levels of AIP, serum osteoprotegerin (OPG) and oligomeric matrix protein (COMP) in CAC group were higher than those in non-CAC group, while the levels of serum fibroblast growth factor 21 (FGF21) were lower than those in non-CAC group, with statistically significant difference (all P<0.01). Correlation analysis showed that CAC score of CAD patients was positively correlated with AIP, OPG and COMP ( r=0.581, 0.451, 0.326, P<0.05), and negatively correlated with FGF21 ( r=-0.294, P<0.05). Receiver operating characteristic (ROC) curve analysis showed that AIP, OPG, COMP and FGF21 had diagnostic value for CAC in CAD patients (all P<0.05). AIP>0.387, OPG>5.150 ng/ml, FGF21>136.35 pg/ml, COMP>733.16 ng/ml were independent factors affecting the formation of CAC (all P<0.05). Conclusions:The increase of AIP and the change of inflammatory factors can be used as markers for the diagnosis of CAC formation in CAD patients.
ABSTRACT
Objective:To investigate the establishment and application value of a radio-mics prediction model for lymph node metastasis of gallbladder carcinoma based on dual-phase enhanced computed tomography (CT).Methods:The retrospective cohort study was conducted. The clinicopathological data of 194 patients with gallbladder carcinoma who were admitted to the First Affiliated Hospital of Xi'an Jiaotong University from January 2012 to December 2020 were collected. There were 70 males and 124 females, aged (64±10)years. All patients underwent curative-intent resection of gallbladder carcinoma. A total of 194 patients were randomly divided into 156 cases in training set and 38 cases in test set according to the ratio of 8:2 based on random number method in R software. The training set was used to establish a diagnostic model, and the test set was used to validate the diagnostic model. After the patients undergoing CT examination, image analysis was performed, radiomics features were extracted, and a radiomics model was established. Based on clinicopathological data, a nomogram prediction model was established. Observation indicators: (1) lymph node dissection and histopathological examination results; (2) establishment and characteristic analysis of a radiomics prediction model; (3) analysis of influencing factors for lymph node metastasis of gallbladder carcinoma; (4) establishment of a nomogram prediction model for lymph node metastasis; (5) comparison of the predictive ability between the radiomics prediction model and nomogram prediction model for lymph node metastasis. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers, and comparison between groups was performed by the chi-square test. Univariate analysis was conducted by the chi-square test, and multivariate analysis was performed by the Logistic regression model forward method. The receiver operating characteristic curve was drawn, and the area under curve, decision curve, confusion matrix were used to evaluate the predictive ability of prediction models. Results:(1) Lymph node dissection and histopathological examination results. Of the 194 patients, 182 cases underwent lymph node dissection, with the number of lymph node dissected as 8(range, 1?34) per person and the number of positive lymph node as 0(range, 0?11) per person. Postoperative histopathological examination results of 194 patients: 122 patients were in stage N0, with the number of lymph node dissected as 7(range, 0?27) per person, 48 patients were in stage N1, with the number of lymph node dissected as 8(range, 2?34) per person and the number of positive lymph node as 1(range, 1?3) per person, 24 patients were in stage N2, with the number of lymph node dissected as 11(range, 2?20) per person and the number of positive lymph node as 5(range, 4?11) per person. (2) Establishment and characteristic analysis of a radiomics prediction model. There were 107 radiomics features extracted from 194 patients, including 18 first-order features, 14 shape features and 75 texture features. According to the intra-group correlation coefficient and absolute median difference of each radiomics feature, mutual information, Select K-Best, least absolute shrinkage and selection operator regression were conducted to further reduce dimensionality. By further combining 5 different machine learning algorithms including random forest, gradient boosting secession tree, support vector machine (SVM), K-Nearest Neighbors and Logistic regression, the result showed that the Select K-Best_SVM model had the best predictive performance after analysis, with the area under receiver operating characteristic curve as 0.76 in the test set. (3) Analysis of influencing factors for lymph node metastasis of gallbladder carcinoma. Results of univariate analysis showed that systemic inflammation response index, carcinoembryonic antigen (CEA), CA19-9, CA125, radiological T staging and radiological lymph node status were related factors for lymph node metastasis of patients with gallbladder cancer ( χ2=4.20, 11.39, 5.68, 11.79, 10.83, 18.58, P<0.05). Results of multivariate analysis showed that carcinoembryonic antigen, CA125, radiological T staging (stage T3 versus stage T1?2, stage T4 versus stage T1?2), radiological lymph node status were independent influencing factors for lymph node metastasis of patients with gallbladder carcinoma [ hazard ratio=2.79, 4.41, 5.62, 5.84, 3.99, 95% confidence interval ( CI) as 1.20?6.47, 1.81?10.74, 1.50?21.01, 1.02?33.31, 1.87?8.55, P<0.05]. (4) Establishment of a nomogram prediction model for lymph node metastasis. A nomogram prediction model was established based on the 4 independent influencing factors for lymph node metastasis of gallbladder carcinoma, including CEA, CA125, radiological T staging and radiological lymph node status. The concordance index of the nomogram model was 0.77 (95% CI as 0.75?0.79) in the training set and 0.73 (95% CI as 0.68?0.72) in the test set, respectively. (5) Comparison of the predictive ability between the radiomics predic-tion model and nomogram prediction model for lymph node metastasis. The receiver operating characteristic curve showed that the areas under the curve of Select K-Best_SVM radiomics model were 0.75 (95% CI as 0.74?0.76) in the training set and 0.76 (95% CI as 0.75?0.78) in the test set, respectively. The areas under the curve of nomogram prediction model were 0.77 (95% CI as 0.76?0.78) in the training set and 0.70 (95% CI as 0.68?0.72) in the test set, respectively. The decision curve analysis showed that Select K-Best_SVM radiomics model and nomogram prediction model had a similar ability to predict lymph node metastasis. The confusion matrix showed that Select K-Best_SVM radiomics model had the sensitivity as 64.29% and 75.00%, the specificity as 73.00% and 59.09% in the training set and test set, respectively. The nomogram had the sensitivity as 51.79% and 50.00%, the specificity as 80.00% and 72.27% in the training set and test set, respectively. Conclusion:A dual-phase enhanced CT imaging radiomics prediction model for lymph node metastasis of gallbladder carcinoma is successfully established, and its predictive ability is good and consistent with that of nomogram.
ABSTRACT
Objective:To analyze the association between the perioperative amplitude-integrated electroencephalogram(aEEG)of neonates with congenital heart disease(CHD) and their neurodevelopmental outcome at 2 years of age.Methods:Neonates with CHD ( n=32) who were admitted to the neonatal intensive care unit at our hospital were included.All patients had undergone cardiac surgery during the neonatal period and preoperative and postoperative aEEG monitoring.The background pattern, sleep-wake cycle(SWC) pattern and seizure activity (including electrographic seizure activity) were used to quantify cerebral activity related to brain function.Infants with CHD were enrolled prospectively to follow up at 2 years old.Participants were assessed at 2 years old via the Bayley Scale of Infant Development. Results:A total of 32 neonates were enrolled in the study.Compared with average of normal population, psychomotor development index(PDI) of participants decreased significantly ( P<0.05). The mental development index(MDI) of patients with abnormal behavior was significantly lower.The longer length of ICU, longer time of ventilation, and the older age of father were risk factors of lower PDI.The MDI (76.29±23.38) of cases with mild abnormal preoperative background pattern were significantly lower than that with normal background pattern (97.37±22.65)( P=0.039). The PDI (74.00±20.09) of cases with abnormal preoperative background pattern was significantly lower than that (92.12±20.42) with normal preoperative background pattern ( P=0.046). The PDI (85.04±20.384) of cases with immature preoperative SWC were significantly lower than that with the normal preoperative SWC(110.00±16.55) ( P=0.027). Conclusion:Abnormal perioperative background pattern and SWC are markers for neurodevelopment disorder.The perioperative aEEG is a useful bedside tool that helps predict outcomes in infants underwent heart surgery.
ABSTRACT
Objective:To investigate the academic burnout level of nursing interns, and to analyze the influence path of nursing professional self-concept and professional values on the academic burnout of nursing interns.Methods:From September to December 2021, 204 nursing students who practiced for 6 months in the First Affiliated Hospital of Anhui Medical University were surveyed using the College Student Learning Burnout Scale, the Nursing Professional Self-Concept Scale and the Nursing Professional Values Scale. Structural equation modeling using AMOS 23.0.Results:The total score of academic burnout was (52.37 ± 11.60), which was in the middle level. The results of correlation analysis showed that the nurses' professional values were negatively correlated with depression, misbehavior, and low sense of achievement ( r=-0.253, -0.256, -0.406), and the differences were statistically significant ( P<0.01). Nursing professional self-concept was negatively correlated with depression, misbehavior, and low sense of achievement ( r=-0.466, -0.414, -0.525), and the differences were statistically significant ( P<0.01). Intern nursing students' nursing occupational self-concept had a partial mediating effect on their professional values and academic burnout, and the mediating effect accounted for 48.57% of the total effect. Conclusions:Professional values of nursing students can directly affect academic burnout, and also indirectly affect them through nursing professional self-concept.
ABSTRACT
Objective: To compare the long-term prognosis of fulminant myocarditis (FM) and non-fulminant myocarditis (NFM) patients who survived and discharged from hospital, and to explore the factors associated with the long-term prognosis and impaired cardiac function. Methods: This study was a retrospective study. Consecutive patients with acute myocarditis hospitalized in Tongji Hospital from January 2017 to December 2020 were enrolled and divided into FM group and NFM group according to the type of myocarditis. Then, patients in the FM group were further divided into normal cardiac function group and impaired cardiac function group according the left ventricular ejection fraction (LVEF). All patients with acute myocarditis were treated with antiviral, immunomodulatory, immunosuppressive medications and symptomatic and supportive treatment, while FM patients were treated with comprehensive treatment plan. Clinical data at admission of enrolled patients were collected through the electronic medical record system. Patients were clinically followed-up at 1, 3, 6 and 12 months, then once a year after discharge by clinical visit. The primary endpoints included major cardiovascular events, impaired cardiac function was defined by LVEF<55%. Kaplan-Meier survival curve was used to analyze the occurrence of LVEF<55% and left ventricular enlargement during the follow-up of patients in FM group and NFM group, and Log-rank test was used for comparison between groups. Cox regression model was used to analyze the risk factors of impaired cardiac function in patients with FM during follow-up. Results: A total of 125 patients with acute myocarditis were enrolled (66 in FM group and 59 in NFM group). Compared with NFM group, the proportion of FM patients with the lowest LVEF<55% during hospitalization was higher (P<0.01), and the recovery time of normal LVEF during hospitalization was longer (P<0.01). The proportion of LVEF<55% at discharge was similar between the two groups (P=0.071). During the follow-up of 12 (6, 24) months, 1 patient (1.5%) died due to cardiac reasons in FM group after discharge, 16 patients (24.2%) had sustained LVEF<55% after discharge, and 8 patients (12.1%) had left ventricular enlargement. In NFM group, 3 patients (5.1%) had sustained LVEF<55%, and 1 patient (1.7%) had left ventricular enlargement. Kaplan-Meier survival curve analysis showed that the incidence of sustained LVEF<55% in FM group was higher than that in NFM group (P=0.003), and the incidence of left ventricular enlargement was also higher than that in NFM group (P=0.024). Subgroup analysis of patients in the FM group showed that, compared with the normal cardiac function group, the time from onset to admission was shorter (P=0.011), the proportion of LVEF<55% at discharge was higher (P=0.039), the proportion of coronary angiography was higher (P=0.014), and the LVEF recovery time during hospitalization was longer (P=0.036) in FM patients with impaired cardiac function. Multivariate Cox regression analysis showed that longer LVEF recovery time during hospitalization was an independent risk factor for cardiac function impairment after discharge of FM patients (HR=1.199, 95%CI 1.023-1.406, P=0.025). Conclusions: The incidence of reduced LVEF is significantly higher in FM patients than that in NFM patients. Longer LVEF recovery time during hospitalization is an independent risk factor for cardiac function impairment in FM patients after discharge.

AIM: The clinical outcomes of unilateral single-focal intraocular len(SIOL), contralateral implanted multifocal IOL(MIOL)and the SIOL was implanted in binoculus were compared.METHODS: There were 60 cases with 120 eyes age-related cataract patients in January 2019 to January 2021 underwent phacoemulsification and IOL implantation in Chengdu Aier Eye Hospital. The SIOL has been implanted in the dominant eyes, all patients were divided into three groups according to the types of IOL implanted in the contralateral non-dominant eyes, among them, there were 36 eyes of 18 cases in group A with non-dominant eyes implanted MIOL(SBL-3); 38 eyes of 19 cases in group B were implanted MIOL(SN6AD1)in non-dominant eyes. SIOL was implanted in all 46 eyes of 23 cases of control group. After operation at 3mo,the results of binocular vision and visual quality of the three groups were evaluated and compared.RESULTS: After operationat 3mo, there was no difference in the uncorrected distance vision and corrected distance vision, uncorrected medium vision and corrected near vision among the three groups(P<0.05).The uncorrected near visual acuity and corrected intermediate visual acuity of both eyes in groups A and B were significantly improved in both groups compared with the control group(P<0.05). The scores of Catquest 9SF-CN scale showed that the quality of life of patients in group A and group B(11.11±1.323, 11.89±1.883 scores)was better than that in the control group(14.65±1.722 scores, both P<0.05). The rate of lens removal in group A, B and control group were 88.9%, 84.2% and 39.1%, respectively, and the rate of lens removal in group A was significantly higher than that in the control group(P<0.0167).CONCLUSION: Dominant eye implantation of SIOL in patients with cataract and contralateral non-dominant eye implantation of MIOL(SBL-3/SN6AD1)can obtain better full-range visual acuity than binoculus, less postoperative adverse visual symptoms, and higher patient disengagement rate and satisfaction.
ABSTRACT
Objective:To investigate the association between body mass index (BMI) trajectories in children and adolescents and subclinical renal damage (SRD) in adulthood.Methods:4 623 participants aged 6-18 years old were recruited from the ongoing cohort of Hanzhong adolescent hypertension study in 1987, and the subjects were followed up in 1989, 1992, 1995, 2005, 2013 and 2017, respectively. Group-based trajectory modeling was used to identify distinct BMI trajectories in longitudinal analysis. Generalized linear model was applied to examine the association between different BMI trajectories and SRD incidence in adulthood.Results:A total of 2 678 subjects from childhood to adulthood were enrolled in this study. All subjects were divided into three groups according to three distinct BMI trajectories: low-increasing BMI group ( n=1 017), moderate-increasing BMI group ( n=1 353), and high-increasing BMI group ( n=308). Over follow up for 30 years, a total of 248 participants (9.3%) developed SRD. Urinary albumin-to-creatinine ratio (uACR) in low to high-increasing BMI group was 0.9(0.6, 1.4), 1.0(0.7, 1.7), 1.6(0.8, 3.2), respectively ( P trend<0.001), and estimated glomerular filtration rate was 98.5(87.6, 111.6) , 96.2(86.4, 109.7), 95.3 (87.5, 125.0) ml·min -1·(1.73 m 2) -1, respectively ( P trend=0.025). The generalized linear model analysis showed that uACR was increased linearly from low to high-increasing BMI group [ β=3.16(95% CI 1.02-5.31), Ptrend=0.004]. There was no correlation or linear trend between BMI trajectory and estimated glomerular filtration rate [ β=-2.30(95% CI-5.18-0.57), Ptrend=0.117]. Compared with the low-increasing BMI group, the high-increasing BMI group had greater odds of experiencing SRD in adulthood after adjusting for multiple confounders such as age, gender, medical history and lifestyle ( OR=2.83, 95% CI 1.84-4.36, Ptrend<0.001). Conclusions:Higher BMI trajectorie is correlated with higher level of uACR and risk of SRD in middle age. Identifying long-term BMI trajectorie from early age may assist in predicting individuals′ renal function in later life.
ABSTRACT
Objective:To investigate the incidence and risk factors of hepatic artery injury during percutaneous transhepatic biliary drainage (PTBD).Methods:From Apr 2002 to Dec 2020, the clinical data of 1 446 patients undergoing PTBD were retrospectively analyzed.Results:Hepatic artery injury occurred in 7 cases, with an incidence of 0.48%. Fluoroscopy guided puncture was used in all cases. In those 7 cases (0.48%) a drainage catheter was failed to put in place after multiple attempts, hepatic artery injury occurred in 1 case; One drainage catheter was inserted in 1 314 cases (90.87%), hepatic artery injury occurred in 5 cases; One hundred and twenty-five cases (8.65%) were implanted with two drainage catheter, and 1 case had hepatic artery injury. Failure to successfully insert the drainage catheter increase the incidence of hepatic artery injury ( OR=0.06,95% CI 0.01-0.71, P=0.026) .There were 1 430 cases (98.89%) with oblique needle tip and 5 cases had hepatic artery injury; There were 16 cases (1.11%) with triangular needle tip and 2 cases had hepatic artery injury. Triangular needle tip increased the incidence of hepatic artery injury( OR=55.57, 95% CI 6.84-451.38, P<0.001). Conclusion:Hepatic artery injury is a rare complication of PTBD.The use of triangular needle and the failure of drainage were the risk factors of hepatic artery injury.
ABSTRACT
Diabetic peripheral neuropathy is a common complication of diabetes， and its pathogenesis is complex. Its high morbidity can result in disability， teratogenesis， and death in diabetic patients. At present， the pathogenesis of diabetic peripheral neuropathy has not been clearly elucidated， which may be related to oxidative stress， inflammatory response， microcirculation dysfunction， metabolic abnormalities， etc. Recent studies have found that apoptosis plays an important role in the pathogenesis of diabetic peripheral neuropathy. The three pathways， i.e.， mitochondrial pathway， death receptor pathway， and endoplasmic reticulum pathway， jointly regulate the cell apoptosis in the body. Traditional Chinese medicine， with definite efficacies in the treatment of diabetic peripheral neuropathy， is advantageous in overall regulation and multi-target and multi-pathway treatment. As reported， the active ingredients in Chinese medicine and Chinese medicinal compounds can alleviate diabetic peripheral neuropathy by regulating apoptosis signaling pathways. Furthermore， apoptosis pathways are expected to be potential targets for new drugs against diabetic peripheral neuropathy following oxidative stress. Therefore， this paper， taking apoptosis as the entry point， reviewed the research progress on TCM intervention in diabetic peripheral neuropathy in recent years to provide references for the clinical prevention and treatment of diabetic peripheral neuropathy and the development of new drugs.
