Changes of cytokines after cardiopulmonary bypass in children with congenital heart disease / 中国小儿急救医学

Objective:To study the changes of cytokines after cardiopulmonary bypass(CPB)in children with congenital heart disease.Methods:A total of 124 children with congenital heart disease underwent CPB surgery at Shanghai Children′s Medical Center from June 2020 to October 2021 with cytokine detection were enrolled.Twelve kinds of cytokines, white blood cell count(WBC)and neutrophil-to-lymphocyte ratio(NLR), C-reactive protein(CRP)and procalcitonin were detected before and 24 hours after operation.All patients were divided into CPB<120 min group ( n=102)and CPB≥120 min group ( n=22)acoording to CPB time, and were divided into systemic inflammatory response syndrome (SIRS) group, compensatory anti-inflammatory response syndrome (CARS) group and control group according to the changes of cytokines.The changes of cytokines, anti-inflammatory factors and pro-inflammatory factors before and after CPB and the correlation with CPB time were analyzed. Results:There were 65 boys and 59 girls with a body weight of(10.69±8.18)kg and a median age of 317(141, 975)d.After CPB, WBC(×10 9/L)(13.47 vs.8.6), NLR(4.93 vs.0.55), and CRP(mg/L)(81.35 vs.0.8) were significantly higher than those before operation( P<0.001). IL-6(pg/mL)(135.69 vs.6.86), IL-8(pg/mL)(33.33 vs.14.95), and IL-10(pg/mL)(6.05 vs.2.44)were significantly higher than those before operation( P<0.001). Compared with CPB<120 min group, IL-6(pg/mL)(211.88 vs.119.47), IL-8(pg/mL)(71.67 vs. 25.39), and IL-10(pg/mL)(7.69 vs. 4.92)in CPB≥120 min group significantly increased( P<0.001). CRP was negatively correlated with CPB time( r=-0.204, P=0.025), while IL-6( r=0.254, P=0.005), IL-8( r=0.358, P=0.001), IL-10( r=0.198, P=0.03) were positively correlated with CPB time.Twelve children(9.7%)had obvious SIRS, and four cases(3.2%)had early CARS.The mortality of CARS group was significantly higher than that of SIRS group and the control group( P=0.011). Conclusion:Il-6 , IL-8, and IL-10 are significantly increased after CPB in children with congenital heart disease.With the increase of CPB time, IL-6 and IL-8 increase significantly, and the correlation between IL-8 and CPB time is the strongest.Although the proportion of children with early postoperative CARS is small, the mortality is high, which indicates clinical surveillance and treatment need to be strengthened for anti-inflammatory response.

Clinical observation of diaphragm plication after pediatric congenital heart disease surgery / 中国小儿急救医学

Objective:To analyze the risk factors of performing diaphragm plication(DPL) after congenital heart disease(CHD) surgery as well as the timing and clinical efficacy.Methods:Data regarding children underwent open heart surgery at Shanghai Children′s Medical Center from January 2017 to December 2019 were reviewed.According to whether DPL was performed after CHD operation or not, the children were divided into DPL group and non-diaphragm plication(NDPL)group.Clinical data including age, surgery, cardiopulmonary bypass(CPB)temperature and time of two groups were compared, meanwhile the risk factors of DPL surgery were analyzed.Based on the median of 8 days between open heart surgery and DPL, children in DPL group were divided into early surgery group(less than 8 days), and delayed operation group(no less than 8 days). The parameters of comparison included ventilator using time, hospital stay time, hospitalization expenditure, postoperative infection to evaluate the timing of DPL and effect.Results:There were 10 309 children after CHD, including 95 in DPL group and 10 214 in NDPL group.In DPL group, there were 52 males(54.7%) and 43 females(45.3%), with age 147(52, 318) d, weight(5.5±4.1) kg, height(56.8±25.6) cm, CPB time(136.8±93.4) min and aortic occlusion time(62.5±50.2) min.Compared with NDPL group, DPL group had younger age, shorter height, lighter weight, higher incidence of preoperative special treatment, higher proportion of reoperation, lower CPB temperature, longer CPB time and longer aortic occlusion time.There were significant differences between two groups( P<0.05). Multivariate Logistic regression analysis showed that younger operative age( OR=0.998, 95% CI 0.998~0.999, P<0.001), staging operation( OR=72.977, 95% CI 39.096~136.211, P<0.001), long CPB time( OR=1.006, 95% CI 1.002~1.011, P=0.008), and pulmonary venoplasty( OR=4.219, 95% CI 2.132~8.350, P<0.001) were independent risk factors for DPL after CHD.Early surgery group had lower postoperative infection rate(43.59% vs. 88.38%, P=0.007), shorter ventilator duration[168.0(99.5, 280.5) h vs.309.9(166.2, 644.5) h, P=0.029], shorter hospital stay duration[27.00(20.75, 35.00)d vs.37.00(28.00, 53.00)d, P<0.001], and lower hospitalization cost[158.36(128.99, 203.11) thousand yuan vs.232.95(174.54, 316.47) thousand yuan, P<0.001] than delayed operation group. Conclusion:Younger age, staging operation, long CPB time, and pulmonary venoplasty are independent risk factors for DPL due to diaphragmatic paralysis after pediatric CHD surgery.Early surgical intervention is beneficial for the recovery of children.

Correlation analysis between hospice care attitude and death depression in undergraduate nursing students / 中国实用护理杂志

Objective:To explore the association between attitudes toward care of the dying and death depression in undergraduate nursing students.Methods:With stratified sampling, 380 undergraduate nursing students in Guangdong Medical University from June to September 2020 were investigated by using a self-designed questionnaire, Frommelt Attitudes Toward Care of the Dying Scale Form B (FATCOD-B-C) and Chinese version of Death Depression Scale-Revised (CCDS-R). Pearson correlation analysis was used to analyze the correlation between hospice care attitude and death depression of nursing undergraduates.Results:The score of FATCOD-B-C of 380 nursing undergraduates was (104.92 ± 7.92) points. The highest average score of dimensions of attitude toward the necessity of family support was (4.02 ± 0.38) points, and the lowest average score of dimensions of attitude toward communication with the dying person was (2.95 ± 0.42) points. The score of CCDS-R was (54.58 ± 12.52) points. The highest average score of dimensions of other death was (3.48 ± 0.80) points, and the lowest average score of dimensions of existential vacuum was (1.78 ± 0.69) points. Pearson analysis revealed that attitudes toward care of the dying had a negative association with death depression ( r=-0.34, P<0.05). Conclusions:Attitudes toward care of the dying of undergraduate nursing students is in a higher level and it has close association with death depression. It is recommended to reduce the death depression level of undergraduate nursing students through hospice care training and carrying out death education, so as to improve the positive attitudes of caring for dying patients.

Risk factors for cryptogenic stroke in patients with patent foramen ovale / 国际脑血管病杂志

Objective:To investigate the potential risk factors for cryptogenic stroke (CS) in patients with patent foramen ovale (PFO).Methods:Patients underwent PFO closure in the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from June 2018 to December 2021 were enrolled retrospectively. Transesophageal echocardiography was used to evaluate the morphological characteristics of foramen ovale and right-to-left shunt (RLS). Multivariate logistic regression analysis was used to determine the independent risk factors for CS in patients with PFO. Results:A total of 203 patients with PFO were enrolled. Their age was 41.9±14.3, and 116 patients (57.1%) were male. There were 102 patients in CS group and 101 patients in non-stroke group. The age, body mass index, systolic blood pressure and diastolic blood pressure, and the constituent ratios of male, hypertension, diabetes, hyperlipidemia and smoking of the CS group were significant higher than those of the non-stroke group (all P<0.05). The PFO channel of the CS group was longer, wider and more combined with resting RLS (all P<0.05). Multivariate logistic regression analysis showed that systolic blood pressure (odds ratio [ OR] 1.065, 95% confidence interval [ CI] 1.022-1.111; P=0.003), PFO length ( OR 1.124, 95% CI 1.004-1.258; P=0.043) and resting RLS ( OR 5.449, 95% CI 2.283-13.004; P<0.001) were the independent risk factors for CS in patients with PFO. Conclusion:Systolic blood pressure, PFO length and the presence of resting RLS are the independent risk factors for CS in patients with PFO.

Sexual Dimorphism of Inputs to the Lateral Habenula in Mice / 神经科学通报·英文版

The lateral habenula (LHb), which is a critical neuroanatomical hub and a regulator of midbrain monoaminergic centers, is activated by events resulting in negative valence and contributes to the expression of both appetitive and aversive behaviors. However, whole-brain cell-type-specific monosynaptic inputs to the LHb in both sexes remain incompletely elucidated. In this study, we used viral tracing combined with in situ hybridization targeting vesicular glutamate transporter 2 (vGlut2) and glutamic acid decarboxylase 2 (Gad2) to generate a comprehensive whole-brain atlas of inputs to glutamatergic and γ-aminobutyric acid (GABA)ergic neurons in the LHb. We found >30 ipsilateral and contralateral brain regions that projected to the LHb. Of these, there were significantly more monosynaptic LHb-projecting neurons from the lateral septum, anterior hypothalamus, dorsomedial hypothalamus, and ventromedial hypothalamus in females than in males. More interestingly, we found a stronger GABAergic projection from the medial septum to the LHb in males than in females. Our results reveal a comprehensive connectivity atlas of glutamatergic and GABAergic inputs to the LHb in both sexes, which may facilitate a better understanding of sexual dimorphism in physiological and pathological brain functions.

The Superior Colliculus: Cell Types, Connectivity, and Behavior / 神经科学通报·英文版

The superior colliculus (SC), one of the most well-characterized midbrain sensorimotor structures where visual, auditory, and somatosensory information are integrated to initiate motor commands, is highly conserved across vertebrate evolution. Moreover, cell-type-specific SC neurons integrate afferent signals within local networks to generate defined output related to innate and cognitive behaviors. This review focuses on the recent progress in understanding of phenotypic diversity amongst SC neurons and their intrinsic circuits and long-projection targets. We further describe relevant neural circuits and specific cell types in relation to behavioral outputs and cognitive functions. The systematic delineation of SC organization, cell types, and neural connections is further put into context across species as these depend upon laminar architecture. Moreover, we focus on SC neural circuitry involving saccadic eye movement, and cognitive and innate behaviors. Overall, the review provides insight into SC functioning and represents a basis for further understanding of the pathology associated with SC dysfunction.

Formation of the Looming-evoked Innate Defensive Response during Postnatal Development in Mice / 神经科学通报·英文版

Environmental threats often trigger innate defensive responses in mammals. However, the gradual development of functional properties of these responses during the postnatal development stage remains unclear. Here, we report that looming stimulation in mice evoked flight behavior commencing at P14-16 and had fully developed by P20-24. The visual-evoked innate defensive response was not significantly altered by sensory deprivation at an early postnatal stage. Furthermore, the percentages of wide-field and horizontal cells in the superior colliculus were notably elevated at P20-24. Our findings define a developmental time window for the formation of the visual innate defense response during the early postnatal period and provide important insight into the underlying mechanism.

Diagnostic values of integrated evidence chain, Roussel Uclaf Causality Assessment Method, and Structured Expert Opinion Process method for drug-induced liver injury / 临床肝胆病杂志

Objective To investigate the clinical applicability and different characteristics of three commonly used diagnostic methods for drug-induced liver injury from the two aspects of liver injury induced by Western medicine and liver injury induced by traditional Chinese medicine. Methods A prospective cohort study was performed for 289 hospitalized patients with acute drug-induced liver injury who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from January 2015 to December 2020 and did not receive integrated traditional Chinese and Western medicine therapy, among whom 187 patients had herb-induced liver injury and 102 had Western medicine-induced liver injury. The 289 patients were diagnosed by the integrated evidence chain (IEC), Roussel Uclaf Causality Assessment Method (RUCAM), and the Structured Expert Opinion Process (SEOP) method, and related data at acute onset were collected, including general information, latency period, detailed medication, and laboratory markers such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase, alkaline phosphatase, and total bilirubin. A statistical analysis was performed to investigate the consistency between IEC, RUCAM, and SEOP in the diagnosis of Western medicine-induced liver injury and herb-induced liver injury and their own applicability. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data; the chi-square was used for comparison of categorical data. Results The hepatocellular type was the main type of clinical liver injury in both Western medicine-induced liver injury and herb-induced liver injury, accounting for 81.4% and 74.3%, respectively, and laboratory examination showed higher levels of ALT and AST. Western medicine-induced liver injury cases were diagnosed by IEC, RUCAM, and SEOP, with a clinical diagnosis rate of 65.7%, 100%, and 63.7%, respectively, and the constituent ratio of Western medicine-induced liver injury was 23.2%, 35.3%, and 22.5%, respectively. Herb-induced liver injury cases were diagnosed by these three methods, with a clinical diagnosis rate of 47.6%, 100%, and 29.9%, respectively, and the constituent ratio of herb-induced liver injury was 30.8%, 64.7%, and 19.4%, respectively. The consistency test of the three diagnostic methods showed that in the diagnosis of Western medicine-induced liver injury cases, there was good consistency between IEC and SEOP (Kappa=0.785, P 0.05) and between RUCAM and SEOP (Kappa=0.117, P > 0.05); in the diagnosis of herb-induced liver injury cases, there was poor consistency between RUCAM and SEOP (Kappa=0.066, P > 0.05), while there was good consistency between RUCAM and IEC (Kappa=0.026, P < 0.05) and between IEC and SEOP (Kappa=0.437, P < 0.05). Conclusion The IEC method shows good applicability for both Western medicine-induced liver injury and herb-induced liver injury, and there is good consistency between IEC and SEOP in the diagnosis of Western medicine-induced liver injury cases, while there is a relatively low level of consistency between IEC and SEOP in the diagnosis of herb-induced liver injury. There is poor consistency between RUCAM and the other two methods. In the clinical diagnosis of Western medicine-induced liver injury, IEC, RUCAM, and SEOP should be used in combination to accurately judge the causal relationship between drugs and liver injury.

An Easily Compatible Eye-tracking System for Freely-moving Small Animals / 神经科学通报·英文版

Measuring eye movement is a fundamental approach in cognitive science as it provides a variety of insightful parameters that reflect brain states such as visual attention and emotions. Combining eye-tracking with multimodal neural recordings or manipulation techniques is beneficial for understanding the neural substrates of cognitive function. Many commercially-available and custom-built systems have been widely applied to awake, head-fixed small animals. However, the existing eye-tracking systems used in freely-moving animals are still limited in terms of their compatibility with other devices and of the algorithm used to detect eye movements. Here, we report a novel system that integrates a general-purpose, easily compatible eye-tracking hardware with a robust eye feature-detection algorithm. With ultra-light hardware and a detachable design, the system allows for more implants to be added to the animal's exposed head and has a precise synchronization module to coordinate with other neural implants. Moreover, we systematically compared the performance of existing commonly-used pupil-detection approaches, and demonstrated that the proposed adaptive pupil feature-detection algorithm allows the analysis of more complex and dynamic eye-tracking data in free-moving animals. Synchronized eye-tracking and electroencephalogram recordings, as well as algorithm validation under five noise conditions, suggested that our system is flexibly adaptable and can be combined with a wide range of neural manipulation and recording technologies.

MouseVenue3D: A Markerless Three-Dimension Behavioral Tracking System for Matching Two-Photon Brain Imaging in Free-Moving Mice / 神经科学通报·英文版

Understanding the connection between brain and behavior in animals requires precise monitoring of their behaviors in three-dimensional (3-D) space. However, there is no available three-dimensional behavior capture system that focuses on rodents. Here, we present MouseVenue3D, an automated and low-cost system for the efficient capture of 3-D skeleton trajectories in markerless rodents. We improved the most time-consuming step in 3-D behavior capturing by developing an automatic calibration module. Then, we validated this process in behavior recognition tasks, and showed that 3-D behavioral data achieved higher accuracy than 2-D data. Subsequently, MouseVenue3D was combined with fast high-resolution miniature two-photon microscopy for synchronous neural recording and behavioral tracking in the freely-moving mouse. Finally, we successfully decoded spontaneous neuronal activity from the 3-D behavior of mice. Our findings reveal that subtle, spontaneous behavior modules are strongly correlated with spontaneous neuronal activity patterns.

An Infrared Touch System for Automatic Behavior Monitoring / 神经科学通报·英文版

Key requirements of successful animal behavior research in the laboratory are robustness, objectivity, and high throughput, which apply to both the recording and analysis of behavior. Many automatic methods of monitoring animal behavior meet these requirements. However, they usually depend on high-performing hardware and sophisticated software, which may be expensive. Here, we describe an automatic infrared behavior-monitor (AIBM) system based on an infrared touchscreen frame. Using this, animal positions can be recorded and used for further behavioral analysis by any PC supporting touch events. This system detects animal behavior in real time and gives closed-loop feedback using relatively low computing resources and simple algorithms. The AIBM system automatically records and analyzes multiple types of animal behavior in a highly efficient, unbiased, and low-cost manner.

Reduced Firing of Nucleus Accumbens Parvalbumin Interneurons Impairs Risk Avoidance in DISC1 Transgenic Mice / 神经科学通报·英文版

A strong animal survival instinct is to approach objects and situations that are of benefit and to avoid risk. In humans, a large proportion of mental disorders are accompanied by impairments in risk avoidance. One of the most important genes involved in mental disorders is disrupted-in-schizophrenia-1 (DISC1), and animal models in which this gene has some level of dysfunction show emotion-related impairments. However, it is not known whether DISC1 mouse models have an impairment in avoiding potential risks. In the present study, we used DISC1-N terminal truncation (DISC1-N

Antiviral effect of entecavir in chronic hepatitis B patients with rtA181V/T mutation / 临床肝胆病杂志

ObjectiveTo investigate the clinical effect of entecavir (ETV) rescue treatment in chronic hepatitis B (CHB) patients at the onset of rtA181V/T mutation. MethodsA total of 174 CHB patients who were treated in the outpatient and inpatient departments of The Affiliated Hospital of Xuzhou Medical University from January 2012 to January 2017 and underwent the detection of drug-resistance mutations of the genes in the reverse transcription (RT) polymerase region were enrolled, among whom there were 72 previously untreated patients and 102 treatment-experienced patients with virological breakthrough or poor response. The association between the previous medication history of nucleos(t)ide analogues and the mutation pattern (including rtA181V/T) was evaluated in the treatment-experienced CHB patients. A total of 155 patients were enrolled, among whom 72 patients had no drug-resistance mutations, 45 had rtA181V/T mutation, and 38 had rtA181V/T+rtN236T mutation. The three groups were compared in terms of virologic response and biochemical parameters at baseline and at weeks 24 and 48 of ETV rescue treatment. The t-test was used for comparison of normally distributed continuous data between two groups, and a one-way analysis of variance was used for comparison between multiple groups; the Kruskal-Wallis H test was used for comparison between multiple groups. The chi-square test was used for comparison of categorical data between two groups. A logistic regression analysis was used to screen out the influencing factors for poor prognosis. ResultsA analysis of the previous medication history of NAs and the mutation patterns for all patients suggested that the patients with the medication history of multiple NAs tended to have multisite mutations and multi-drug resistance (χ2=4295, P＜0.05). The level of HBV DNA at the time of virological breakthrough was lower than that at the time of initial administration of NAs in the rtA181V/T mutation group ［(6.22±1.48) log10 IU/ml vs (7.08±1.59) log10 IU/ml, t=3.098, P=0.002］ and the rtA181V/T+rtN236T mutation group ［(5.94±1.45) log10 IU/ml vs (6.94±1.61) log10 IU/ml，t=2.850, P=0.004］. At week 48 of ETV rescue treatment, there were no significant differences between the three groups in HBV DNA negative conversion rate (83.3% vs 82.2% vs 81.6%, P＞0.05) and HBeAg negative conversion rate (22.2% vs 17.8% vs 21.1%, P＞0.05), and there were also no significant differences in alanine aminotransferase normalization rate (77.1% vs 85.2% vs 83.3%, P＞0.05), aspartate aminotransferase normalization rate (80.4% vs 75.9% vs 76.0%, P＞0.05), and total bilirubin normalization rate (80.8% vs 79.3% vs 78.1%, P＞0.05). HBV DNA level at the beginning of ETV treatment was the risk factor for the treatment outcome of 48-week antiviral therapy (odds ratio = 1.655, 95% confidence interval: 1.128-2.428, P=0.01). ConclusionETV has a good antiviral effect in treatment-experienced CHB patients with rtA181 drug-resistance mutation, and HBV DNA level at the initiation of ETV treatment can predict the outcome of 48-week ETV rescue treatment.

In silico cloning, expression and bioinformatics analysis of NtODB from common tobacco / 生物工程学报

It has been reported that ODB genes play an important role in homologous recombination-directed DNA repair, suggesting their potential applications in plant breeding. To analyze the expression characteristics of tobacco NtODB gene, the cDNA sequence of NtODB was obtained using in silico cloning technique. The physicochemical properties, signal peptide, and advanced structures of the predicted protein were analyzed using bioinformatics tools. The results showed that the NtODB gene has a 579-bp open reading frame which encodes a protein with 192 amino acid residues. The protein NtODB is predicted to be alkaline and hydrophilic. Real-time quantitative PCR showed that NtODB was constitutively expressed in different tissues. Subcellular localization showed that NtODB was mainly expressed in cell membrane and chloroplast. These results may help us to better understand and elucidate the roles of ODB genes in the homologous recombination-directed DNA repair.

Working memory span training improves working memory capacity / 中华行为医学与脑科学杂志

Objective:To explore whether working memory span training can expand working memory capacity.Methods:A randomized controlled trial design was adopted and a total of 60 healthy college students were recruited and randomly divided into training group ( n=30, receiving adaptive training of spatial breadth task) and control group ( n=30, receiving non-adaptive training of low difficulty spatial breadth task). The cognitive behavior and event-related potential (ERP) data of all subjects when completing the change awareness task were collected before and after training.The SPSS 22.0 statistical software was used for data analysis. The differences between the training group and the control group before and after training were compared by repeated measurement analysis of variance. Results:Repeated measurement ANOVA showed that there were significant time and group interactions at the levels of cognitive behavior(K score, F=5.352, P=0.025) and ERP (CDA, F=4.644, P=0.037) levels. Further post test found that compared with pre-training (pre-test), the K-score ((0.51±0.93), (1.61±1.07), F=26.81, P<0.001) and CDA ((-1.49±1.07)μV, (-2.03±0.94)μV, F=4.731, P=0.041) of the training group increased significantly after training (post-test), and there was no significant difference in K-score and CDA of the control group before and after training (boh P>0.05). Conclusion:Working memory span task can be used as an effective training paradigm to improve working memory capacity.

Outcome of extracorporeal membrane pulmonary oxygenation after congenital heart diseases in pediatric: experience from single center / 中国小儿急救医学

Objective:To review the clinical prognosis and causes of death in children with extracorporeal membrane pulmonary(ECMO) assistance after congenital heart disease(CHD) operation in our center, so as to improve the survival rate of ECMO.Methods:All clinical data of 105 children with VA-ECMO assisted after CHD operation who were admitted to the Department of Cardiothoracic Surgery at Shanghai Children′s Medical Center from January 2017 to December 2019 were collected, and the clinical characteristics and causes of death were retrospectively analyzed.Results:The age of 105 children with ECMO was 110(38, 341)days, the weight was 5.30(3.75, 8.45)kg, and the risk adjustment for congenital heart surgery score was 3(2-3)points.There were no statistically significant differences in gender, age, weight, height, risk adjustment for congenital heart surgery score, the number of ECMO installed in the operating room, the number of ECMO installed after cardiopulmonary resuscitation and ECMO duration between the surviving group ( n=51) and the death group ( n=54)( P>0.05). While there was a significant difference in utilization of continuous renal replacement therapy[7.8% (4/51) vs.38.9% (21/54), P<0.001]. The death mainly occurred within one week after evacuating ECMO(83.3%, 45/54). ECMO installation was most in children aged 1 month to 1 year old(52.4%, 55/105), and the survival rate showed a rise over three years(2017 to 2019), increased from 31.6% (6/19) to 65.0% (13/20). Children with 3 to 5 kg were the most affected (39.0%, 41/105) when ECMO was installed, and the survival rate from 2017 to 2019 increased from 28.6%(4/14) to 75.0%(9/12). The main cause of death was heart failure(48.1%, 26/54), followed by bleeding(18.5%, 10/54)and pulmonary hypertension(13.0%, 7/54). Conclusion:With the progress of surgical technology and cardiopulmonary bypass, and the improvement of postoperative management, the mortality of children with CHD in our hospital after ECMO has decreased year by year during the last three years.However, the mortality of children requiring continuous renal replacement therapy assistance during ECMO is higher.Therefore, it is still necessary to strengthen the maintenance of each organ function during ECMO.

Research progress of anxiety and depression in adult patients undergoing cardiac surgery / 中国胸心血管外科临床杂志

@#Anxiety is a strong behavioral and psychological reaction with fear components, while depression is a mental disorder dominated by high or low mood, both of which are accompanied by cognitive and behavioral changes, and are common comorbidities in patients with heart disease. Cardiac surgery is one of the important factors which trigger specific emotional and physiological reactions of patients. Persistent or initial depression and anxiety after surgery will not only increase surgical complications, short- or long-term mortality and medical costs, but also seriously affect patients' social function and quality of life. With the transformation of bio-psycho-social medical model, it is necessary to evaluate the perioperative psychological state and biological risk of patients undergoing cardiac surgery. This article reviews the characteristics, related mechanisms and therapeutic interventions of anxiety and depression in patients undergoing cardiac surgery.

Clinical features of Caroli disease: An analysis of 41 cases / 临床肝胆病杂志

ObjectiveTo investigate the clinical features of patients with Caroli disease. MethodsThe clinical data were collected from 41 patients who were diagnosed with Caroli disease in The Fifth Medical Center of Chinese PLA General Hospital from April 2015 to January 2020, and the patients were divided into type I group with 16 patients and type Ⅱ group with 25 patients. A retrospective analysis was performed for general information, laboratory markers, and clinical features. The independent samples t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data; a Spearman correlation analysis was also performed. ResultsThe type Ⅰ group had a significantly higher level of albumin (Alb) than the type Ⅱ group (t=0.976, P=0.048), and the type Ⅱ group had a significantly higher prothrombin time (PT) than the type I group (Z=3.115, P=0.001). Compared with the type I group, the type Ⅱ group had significantly higher incidence rates of esophageal and gastric varices, upper gastrointestinal bleeding and/or tarry stool, and portal hypertension (χ2=6.077, 5.468, and 2.403, P=0.002, 0.019, and 0.028). In the patients with type Ⅱ Caroli disease, the level of cholinesterase was negatively correlated with the incidence rates of esophageal and gastric varices and portal hypertension (r=-0.468 and -0.436, P=0.018 and 0.029); Alb level was negatively correlated with the incidence rate of esophageal and gastric varices (r=-0.561, P=0.004); red blood cell count was negatively correlated with the incidence rates of esophageal and gastric varices, upper gastrointestinal bleeding and/or tarry stool, and portal hypertension (r=-0.662, -0.566, and -0.436, P＜0.001, P=0.003, and P=0.029); hemoglobin count was negatively correlated with the incidence rates of esophageal and gastric varices, upper gastrointestinal bleeding and/or tarry stool, and portal hypertension (r=-0.605, -0.590, and -0.510, P=0.001, 0.002, and 0.009); PT was positively correlated with the incidence rates of esophageal varices and portal hypertension (r=0.488 and 0.520, P=0.013 and 0.008). ConclusionCompared with the patients with type I Caroli disease, the patients with type Ⅱ Caroli disease have a higher incidence rates of esophageal and gastric varices, upper gastrointestinal bleeding and/or tarry stool, and portal hypertension, with the changes in clinical indicators such as the decrease of Alb level and the increase of PT level, and they tend to have poor prognosis.
