Objectives: To evaluate the effects of steatotic donor livers on the safety of donors and the prognosis of donors and recipients in pediatric living donor liver transplantation. Methods: A total of 814 pediatric living donor liver transplantations were performed between January 2013 and December 2020 at Department of Pediatric Organ Transplantation,Tianjin First Central Hospital.The clinical data were collected and a retrospective study was conducted.The recipients and the donors were divided into non-steatotic donor liver group(n=733) and steatotic donor liver group(n=81) according to whether the donor graft had steatosis. The recipients and the donors in the steatotic donor liver group were further divided into mild and moderate steatosis groups based on the degree of liver steatosis.Among the donors of non-steatosis donor group,there were 307 males and 426 females,with a median age of 30 years(range:18 to 57 years);the recipients included 351 males and 382 females,with a median age of 7 months(range:4 month to 14 years).Among the donors of steatosis donor group,there were 41 males and 40 females,with a median age of 31 years(range:22 to 51 years);the recipients included 34 males and 47 females,with a median age of 8 months(range:5 months to 11 years).The donors and the recipients were followed up regularly by means of outpatient reexamination and questionnaire survey after operation.Statistical analysis of data between groups was performed using t-test,Wilcoxon rank-sum test,repeated measures ANOVA,χ² test,or Fisher's exact test,respectively.The survival curves of recipients and grafts in different groups were created by Kaplan-Meier method,and the survival rates of the steatotic donor liver group and the non-steatotic donor liver group were compared by Log-rank method. Results: There was no significant difference in the gender of donors in both groups (P=0.132).There were significant differences in the age and blood type distribution as well as body weight and body mass index(all P<0.05) between the two groups.No significant difference was seen in the recovery of liver function markers ALT and AST at 1,2,5 days and 1 month after operation (all P>0.05) between the two groups.The steatotic donor liver group showed longer operation time ((294±75) minutes vs. (264±81) minutes; t=3.149,P=0.002),increased incidence of postoperative biliary leakage (3.7%(3/81) vs. 0.5% (4/733); P=0.025) and delayed incision healing (7.4%(6/81) vs. 2.0%(15/733); P=0.013).There were no significant differences in gender,age,blood type distribution,height,weight and pediatric end-stage liver disease score of recipients between the two groups (all P>0.05).As compared to the non-steatotic donor liver group,the steatotic donor liver group showed similar levels of ALT, AST and total bilirubin within 2 weeks after operation(all P>0.05). The cumulative recipient survival rates in both groups were both 96.3%,the cumulative graft survival rates were 96.3% and 95.5%,respectively,without significant difference(both P>0.05). No statistical difference was observed in the incidence of major complications between the two groups (all P>0.05). There was no significant difference in the recovery of liver function markers of donors and recipients between mild and moderate steatosis groups(all P>0.05).The cumulative recipient survival rates were both 95.9% and the cumulative graft survival rates were both 100% in mild and moderate steatosis groups,without significant difference(P=0.592). Conclusions: The application of mild to moderate steatotic donor livers in pediatric living donor liver transplantation may prolong the operation time of donors,increase the incidence of complications such as biliary leakage and delayed incision healing. But there is no significant impact of mild to moderate steatotic donor livers on the overall postoperative recovery of donors and recipients,and the prognosis is ideal.

Blastocystis hominis is a parasite that parasitizes in the intestines of humans and animals, and is closely related to a variety of gastrointestinal diseases such as abdominal pain and diarrhea. B. hominis is distributed worldwide, and the prevalence of B. hominis infections and dominant subgenotypes vary in countries and in regions from the same country. This paper reviews the global prevalence of B. hominis human infections, its subtypes and geographical distribution, so as to provide insights into the understanding of the global epidemiology of B. hominis and the management of B. hominis infections.

Blastocystis hominis is a common parasitic protozoa in human and animal intestines; however, its pathogenicity remains controversial. Construction of animal models is of great significance to investigate the pathogenicity, pathogenic mechanisms and drug screening of B. hominis. Experimental animals, mode of infections, parasite strains and host immune status are important factors affecting the successful modeling of B. hominis infections in animals. Hereby, we review the progress of researches on animal models of B. hominis infections, and summarize the influencing factors and application of animal models of B. hominis infections, in order to provides insights into the selection of animals models of B. hominis infections.

Network pharmacology and bioinformatics technology were used to predict the mechanism of action of Fuzi-Lizhong pill (FLP) in the treatment of ulcerative colitis (UC). 26 components (23 prototype compounds and 3 metabolites) in the blood of FLP were selected as the research objects. PharmMapper database, SwissTargetPrediction platform, GeneCards and OMIM database were used to screen and predict potential targets of FLP in blood. The protein-protein interaction network model was constructed by using String database and Cytoscape software. DAVID platform, KEGG and Reactome databases were used for GO analysis and pathway analysis of potential targets. Network of drug ingredients-targets-pathways was constructed by Cytoscape software. AutoDock vina software was used to dock the molecules of the absorbed ingredients of FLP in blood with the key targets. 82 potential targets of FLP for treatment of UC were obtained. Potential targets mainly involve biological processes such as response to organic substance, regulation of apoptosis, regulation of programmed cell death, which played roles in the treatment of UC by adjusting pathways in cancer, Colorectal cancer, Vascular endothelial growth factor signaling pathway, Mitogen-activated protein kinase signaling pathway, arachidonic acid metabolism and the other signal pathways. From the perspective of network pharmacology, this study predicted the mechanisms of action of FLP in treating UC, indicating that FLP in treating UC had the characteristics of multiple ingredients, multiple targets and multiple pathways, which laid a foundation for further research.

Objective:To investigate the correlation between antiplatelet agents and the risk of ruptured intracranial aneurysm.Methods:Patients with intracranial aneurysm admitted to the Department of Neurology, East Hospital Area of Qingdao Municipal Hospital from June to December 2018 were selected retrospectively. The baseline data of patients and the characteristics of intracranial aneurysms were collected. The independent correlation between antiplatelet agents and the risk of ruptured intracranial aneurysm was identified by the univariable analysis and multivariate logistic regression analysis. Results:A total of 90 patients with intracranial aneurysm were included in the study. There were 31 males (34.44%) and 59 females (65.56%). The median diameter of the aneurysm was 4 mm. Forty-six patients taking antiplatelet agents before being diagnosed with intracranial aneurysm, of which 36 taking aspirin, 3 taking clopidogrel, and 7 taking aspirin+ clopidogrel. There were 31 patients (34.44%) with ruptured aneurysm and 59 (65.56%) with unruptured aneurysm. There were statistical differences in the proportion of patients with age <60 years ( P<0.05), diabetes ( P<0.1), ischemic heart disease ( P<0.05), history of previous stroke or transient ischemic attack ( P<0.01), internal carotid artery aneurysm ( P<0.01), anterior communicating artery aneurysm ( P<0.05), posterior communicating artery aneurysm ( P<0.01) and taking antiplatelet agents before diagnosis ( P<0.1) between the ruptured group and the unruptured group. Multivariate logistic regression analysis showed that age <60 years (odds ratio[ OR] 4.116, 95% confidence interval [ CI] 1.337-12.673; P=0.014), anterior communicating artery aneurysm ( OR 5.015, 95% CI 1.155-22.559; P=0.032) and posterior communicating artery aneurysm ( OR 68.796, 95% CI 6.762-699.951; P<0.001) were the independent risk factors for ruptured intracranial aneurysm, and taking antiplatelet agents was an independent protective factor for ruptured intracranial aneurysm ( OR 0.320, 95% CI 0.104-0.992; P=0.048). Conclusions:Taking antiplatelet agents, especially aspirin, does not increase the risk of ruptured intracranial aneurysm, but may be a protective factor of ruptured intracranial aneurysm. Unruptured aneurysms are not contraindications for antiplatelet therapy in patients with clear indications.

Objective:Based on the previous studies, to investigate the dissolution behavior of Fuzi Lizhongwan by simultaneously determining the dissolution of benzoylmesaconine, benzoylaconine and benzoylhypaconine in Aconiti Lateralis Radix Praeparata. Method:The simultaneous determination of benzoylmesaconine, benzoylaconine and benzoylhypaconine in Fuzi Lizhongwan was established by HPLC-QQQ-MS. The dissolution amounts of three compositions in 15 batches of Fuzi Lizhongwan from 5 manufacturers at different time points, the cumulative dissolution was calculated and the dissolution curve was drawn. The f₂ similarity factor method was adopted to evaluate similarity of dissolution curves of index components in different batches of samples from the same manufacturer, and to evaluate similarity of dissolution curves of samples from different manufacturers based on the same index component. The dissolution model of Fuzi Lizhongwan was concluded by fitting with the dissolution data. Result:When hydrochloric acid solution with pH of 1.2 was used as the dissolution medium, the three alkaloids had the best dissolution effect. The dissolution behavior of three monoester alkaloids in Fuzi Lizhongwan was basically synchronous and the dissolution lasted for 24 h. Three batches of samples from the same manufacturer (manufacturer 1, 3, 4 and 5) appeared to be similar on dissolution behavior, indicating that the dissolution behavior of the majority of samples from different manufacturers was similar. The dissolution behavior of batch 1 sample was different from batch 2 and 3 samples in manufacturer 2, suggesting that the quality of different batches of samples in manufacturer 2 might be different. The fitting results of dissolution data of index components in samples from different manufacturers were consistent, and the Weibull model was the best. Conclusion:Index components in fifteen batches of samples from 5 manufacturers are continuously dissolved within 24 h, indicating that the samples have the characteristics of slow dissolution. The dissolution curves of samples from the same manufacturer are similar to each other, indicating that the quality of different batches of products from most manufacturers is stable. The dissolution behavior of benzoylmesaconine, benzoylaconine and benzoylhypaconine in samples form different manufacturers has some differences, which may be caused by the source of medicinal materials and preparation technology parameters.

Objective To study a method for monitoring multichannel electrode-scalp contact impedances in electrical impedance tomography (EIT), and to provide support for exploring the impact of contact impedances on imaging and the suppression method.Methods A reference electrode was introduced for the system,placed on the back of the neck or the top of the head. In the spare time of boundary voltage signal acquisition phase, the method of two electrodes was adopted to measure the electrical impedance between each imaging electrode and reference electrode, which was used to analyze the characteristics of multichannel contact impedances.Based on the existing EIT hardware system,the module for monitoring multichannel contact impedance was implemented.Results The calibration board test showed that the measurement error of this method was less than 1‰,and the maximum relative fluctuation of the measurement result within 10 hours was less than 1‰. Preliminary human test indicated that this method had the ability to obtain two kinds of information about spatial consistency and temporal stability of 16-channel contact impedances. Conclusion This method has high accuracy and stability,so it meets the requirements of monitoring multichannel contact impedances in brain EIT.

Objective To evaluate the effect of damped least-square algorithm on the identification of focal bidirectional electrical impedance perturbation in the intracranial area, and to analyze the influence of this kind of perturbation on the reconstruction quality of electrical impedance tomography. Methods Focal bidirectional electrical impedance perturbation was built based on the three-dimensional model and damped least-square algorithm was introduced into imaging. The position error and resolution were used to evaluate the imaging performance.Results When the focal electrical impedance perturbation existed,the target whose conductivity varied greatly or volume was large was more likely to be identified in the images while the target with smaller volume or variable conductivity presented in the reconstruction image was not obvious. It's pointed out that it may cause reconstruction images in some cases could not truly reflect the location and change information of the object of primary cerebral hemorrhage.At the same time,it affected the reconstruction precision,causing the position error and resolution with large fluctuation. Conclusion In reconstruction algorithm linearity correct matrix introduced for bidirectional electrical impedance perturbation contributes to enhancing the recognition of bidirectional perturbation, so that the characterization of the electrical impedance imaging can be augmented for clinical intracerebral hemorrhage.

Objective To explore the association of nocturnal serum cortisol levels with diabetic microvascular complications in overweight or obese patients with type 2 diabetes mellitus. Methods Serum cortisol levels of 316 overweight or obese type 2 diabetic patients were tested at midnight by the method of chemiluminescence. Diabetic microvascular complications were compared among various groups according to nocturnal serum cortisol levels. All the patients with nocturnal serum cortisol level > 50 nmol/L were asked to undergo overnight low-dose dexamethasone suppression test to rule out the possibility of subclincal Cushing's syndrome. The incidences of diabetic nephropathy ( DN ) , diabetic retinopathy ( DR ) , and diabetic peripheral neuropathy ( DPN ) were examined in all the patients. Results (1)The incidence of DN was gradually increased from 13.3％to 27.7％and 44.2％in patients with low, medium, and high cortisol level groups, showing a statistical difference among 3 groups ( P<0.05) . The incidences of DR in medium and high cortisol level groups were higher than that in low cortisol level group (40.6％and 47.7％vs 22.7％, both P<0.01). The incidence of DPN in high cortisol level group was higher as compared with low cortisol level group (60.5％ vs 38.7％, P<0.01). (2) Nocturnal serum cortisol level in patients with diabetic microvascular complications was higher than that in patients without complications [ (136.87 ± 105.78 vs 97.55 ± 93.48) nmol/L, P<0.01]. Nocturnal serum cortisol level in patients with multiple diabetic microvascular complications was higher than that in patients with single diabetic microvascular complication [ (151.66±114.54vs117.69±90.26)nmol/L,P<0.05].(3)Singlefactorlogisticregressionanalysisshowedthat higher nocturnal serum cortisol level was a risk factor for diabetic microvascular complications in addition to female, age, longer diabetic duration, higher fasting plasma glucose ( FPG ) . Multivariate logistic regression analysis showed that higher nocturnal serum cortisol level was still a risk factor for diabetic microvascular complications after adjusted by diabetic duration, FPG, HbA1C, and the use of insulin (P=0.013). Conclusion Nocturnal serum cortisol level seems to be a risk factor for diabetic microvascular complications in overweight or obese patients with type 2 diabetes mellitus.
