Sepsis associated encephalopathy (SAE) features are the diffuse cerebral dysfunction induced by the systemic response to the infection,without clinical or laboratory evidence of direct brain infection or other types of encephalopathy.The core feature of SAE is a diffuse disturbance in cerebral function free of any lateralizing signs.The primary clinical feature of SAE is a change in mental status,especially that of consciousness and cognition.The key prerequisite for the diagnosis of SAE is presence of extracranial infection.There is no precise criteria for the diagnosis of SAE or exclusion of it,and no well-established clinical or biological markers are available.But,neural electrophysiological examination,cranial imaging and biomarkers have been found with implications for the diagnosis of SAE.At present,treatment options for SAE are limited.Things of significant importance are early identification of change in mental status,searching for pathogens and lesions,as well as prompt anti-infectious treatment,maintaining hemodynamic stability and supporting therapy.

0.5).The above results show that feeding regime has significant influence on Zn nutriture but not on Cu nutriture. The Zn nutriture of breast-fed infants is superior to that of bottle-fed infants due to better bioavaila-bility of Zn in human milk.The Cu nutriture in early infancy may depend mainly on the fetal storage of Cu in tissues and its mobilization afterbirth.

Objective To evaluate the effect of pressure load of avascular necrosis of the femoral head(ANFH) by percutaneous injection of polymethylmethacrylate(PMMA).Methods Models of ANFH were established in 20 adult white rabbits with 40 femoral heads which were induced by injection of hydrochloride(HCL) and hormone.DR was performed to observe the bony density of femoral head in all rabbits,the cystic degeneration and collapse of femoral head were detected in 21 femoral heads,then DSA was done to observe the blood supply and they were divided into three groups at random,group A in 5 was examined by pathology,group B in 8 was injected with PMMA and group C was as control.The test of pressure loading was performed in group B and C.Results Of 21 femoral heads with cystic degeneration and collaps,8 were in the HCL-induced group and 13 were in the hormone-induced group.DSA showed that the blood supply was decreased,and the arteria were decreased in diameter.After the percutaneous injection of PMMA,all of 8 rabbits in experimental group were successful.The distinction between the means of two samples was significant in loading test(P

The pathogenesis of diabetes is complicated by several factors including autoimmunity, environment, heredi?ty, and etc. Autophagy is a kind of intracellular biodegradation processes, which plays an important role in intracellular ho?meostasis of islet cells. In diabetes, autophagy is involved in the endoplasmic reticulum stress, mitochondrial dysfunction and inflammatory, and it affects the development of the disease. In this paper, we reviewed the interactions of autophagy with endoplasmic reticulum stress and mitochondrial dysfunction with inflammation in diabetes in order to investigate the patho?genesis of diabetes, to find new strategies for prevention or treatment of diabetes.

Objective The purpose of this paper was to use a new biphasic poroelastic tibia model to develop a two-dimensional numerical method for simulating impact responses of human tibia in car-pedestrian accidents. Methods The geometry of tibia model was reconstructed from CT scans of the left tibia of a living human volunteer. A poroelastic approach was utilized to establish the governing equations of the model and the finite element method was applied to solve these governing equations. Both cortical and cancellous components of tibia were represented using a poroelastic material model consisting of solid phase (matrix) and fluid phase (marrow). A lateral-medial impact direction was selected in the simulation analysis and the impact responses of the pedestrian tibia during 0-200 ms were analyzed. Results The bending deformation of the tibia predicted by the computer simulation was primarily concentrated on the impact zones. The displacement response of Node 107 in the impact zone indicated a peak displacement of -6 mm at around 75 ms, and the significant time delay between the impact force and the displacement response of the skeleton. The axial stress response at the center of element E77 in the impact zone indicated a peak stress of 140 MPa at around 30 ms,and the significant time delay was observed between the impact force and the axial stress response of the skeleton, too. Conclusion This research developed a two-dimensional numerical method for simulating impact responses of human tibia in car-pedestrian accidents. It was able to approximately simulate the bending deformation, lateral displacement response and axial stress response of pedestrian tibia in the impact zones,and the effects of the fluid phase on the solid phase. More in-depth investigation is helpful to further the biofidelity of tibia dynamics model.

Objective:To investigate the association between serum thyroid level and prognosis of critically ill children with euthyroid sick syndrome(ESS).Methods:The clinical data and serum thyroid hormone levels of 176 children with ESS who were admitted to the Department of Pediatric Intensive Care Medicine at West China Second Hospital of Sichuan University from January 2015 to April 2021 were retrospectively collected.According to the prognosis, the children were divided into improved group and invalid group, as well as basic disease group and non basic disease group, and the differences of thyroid hormone between two groups were compared.The pediatric risk of mortality Ⅲ(PRISMⅢ) scores within 24 hours of admission were assessed, and the correlation between thyroid hormone level and PRISMⅢ score was analyzed.Results:Among 176 critically ill children with ESS, the most common diseases were sepsis(31.8%), severe pneumonia (23.8%) and heart failure(10.7%), respectively.The levels of free T3(FT3), T3, free T4(FT4) and T4 in invalid group were significantly lower than those in improved group ( P<0.05), but there was no statistical difference in thyroid-stimulating hormone(TSH) level between two groups( P>0.05). The levels of FT3, T3, FT4 and T4 were negatively correlated with PRISMⅢ score( r=-0.419, -0.459, -0.341, -0.383, respectively, P<0.05), and there was no correlation between TSH level and PRISMⅢ score ( P>0.05). The common underlying diseases of severe children with ESS were malnutrition(31/98), heart disease(30/98), hematologic neoplasms(15/98), and bronchopulmonary dysplasia(10/98). The median age of children in basic disease group was younger than that in non-basic disease group(0.7 years old vs. 2.0 years old, P<0.05); The proportion of children with underlying diseases in invalid group was 24.5%, which was significantly higher than that of children without underlying diseases (6.4%), and the difference was statistically significant ( P<0.05); There were no significant differences in the levels of FT3, T3, FT4, T4 and TSH between two groups ( P>0.05). Conclusion:In critically ill children, a variety of diseases can lead to ESS, and sepsis is the most common disease.Young children with underlying diseases should be more alert to ESS.The more severe the disease, the greater the decline of FT3, T3, FT4 and T4 levels.When low T3, T4 and TSH occur simultaneously, the prognosis of the children may be worse.Thyroid hormone level could be used as an indicator to evaluate the prognosis of critically ill children, which is needed further studies to explore.

Objective To explore the correlation between serum vitamin D levels,vitamin D receptor gene polymorphism,and the incidence of chronic urticaria in children,and to provide clinical evidence for screening the genetic susceptibility of chronic urticaria in children.Methods Clinical data and peripheral blood samples were collected from 100 children with chronic urticaria in the test group and 100 healthy children in the control group who were admitted to the Dermatological Department of Pingshan Distinct Maternal and Child Health Hospital from December 2021 to January 2023.Chemiluminescent assays were used to measure the levels of 25(OH)D,IgE and IgG.PCR amplification was performed to amplify the VDR gene polymorphic sites ApaI,BsmI,TaqI,FokI,and Tru9I,followed by sequencing to assess the VDR gene polymorphism and the expression levels of the associated genetic polymorphic sites rs7975232,rs1544410,rs731236,rs2228570,and rs757343.Results The levels of 25(OH)D in the test group were lower than that in the control group,while IgE and IgG levels were higher than those in the control group,and the differences were statistically sig-nificant.Multivariate logistic regression analysis showed that the T allele of rs757343 was a risk factor for the incidence of chronic urticaria in children(OR=1.45 8,95％CI:1.015-2.153,P=0.047),while the CC geno-type of rs757343 and 25(OH)D were protective factors(OR=0.250,95％CI:0.056-0.786,P=0.031;OR=0.553,95％CI:0.373-0.713,P＜0.001).ROC curve analysis showed that the area under the curve for 25(OH)D,white blood cell count,neutrophil percentage,lymphocyte percentage,and basophil percentage were 0.928,0.701,0.808,0.797 and 0.753,all＞0.7.Conclusion Vitamin D can assist in the diagnosis of uricaria in children and evaluate the progression of the disease.25(OH)D is a protective factor for the onset of chronic urticaria in children,the T allele of the VDR gene polymorphism rs757343 is a risk factor for chronic urticaria in children,while the CC genotype is a protective factor.

Objective To study clinical characteristics of type 2 diabetic(T2D)patients with metabolic syndrome(MS)and its components in Beijing urban communities.Methods Totally,3295 T2D patients involved in a combined prospective diabetic management study from 15 urban communities in Beijing were classified as four groups, according to 2004 Chinese Diabetes Society's definition of MS, i. e, isolated T2D, T2D with one component of MS, T2D with two components of MS and T2D with three components of MS. Their clinical characteristics were analyzed. Results ( 1 ) Among 3295 T2D patients, 155 (4. 7% )were isolated T2D, 107 (32.6%) T2D with one component of MS, 1386 (42.1%) T2D with two components of MS and 679 (20.6%) T2D with three components of MS, with an overall 62.7% (2065/3295) of T2D patients complicated with MS. (2) In these T2D patients, the more components of MS they had, the higher body mass index (BMI), waist circumference, waist to hip circumference ratio (WHR),systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting serum levels of insulin and triglyceride (TG) and the lower level of high-density lipoprotein-cholesterol (HDL) were presented (P <0. 01 ). (3) Percentage of isolated T2D in women increased from 49. 0% (76/155) to 61.9% (420/679)of those with three components of MS ( P < 0 01 ), with increasing of components of MS. (4) Multiple logistic regression analysis showed that BMI, history of hypertension, decreased HDL, increased TG,increased blood pressure, all were risk factors for T2D patients complicated with MS. Conclusions Among T2D patients in urban communities of Beijing, 95.3% (3140/3295) of them complicated with one or more components of MS, and 61.9% (420/679) of them complicated with MS. So, community diabetic management must be implemented in an all-round way, including control of blood pressure, blood lipids,body weight and so on, in addition to control of blood sugar.

Objective To investigate the prevalence of dyslipidemia in subjects with type 2 diabetes mellitus in Beijing urban communities.Methods Total 3316 subjects with type 2 diabetes (age 20-80 years) were recruited from 15 urban community health centers in Beijing using a multi-stage random sampling approach.Dyslipidemia was diagnosed according to Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults:2007 version.Results Among 3316 diabetic subjects (1329 malesand 1987 females),75.6％ (2506/3316) had dyslipidemia,the prevalence was 72.5％ (964/1329)in men and 77.6％ (1542/1987) in women.The prevalence of hypertriglyceridemia and hypercholesterolemia was 41.9％ (1388/3316) and 48.1％ (1595/3316),respectively.31.5％ (1043/3316) subjects had high levels of low-density lipoprotein cholesterol (LDL-C) and 21.2％ (703/3316) had low high-density lipoprotein cholesterol (HDL-C).Among all subjects with dyslipidemia only 22.9％ (575/2506) took hypolipid agents.The overall blood lipid control rates of triglyceride (TG),total cholesterol (TC),LDL-C and HDL-C in 1393 subjects with dyslipidemia history were 48.0％ (669/1393),17.4％ (242/1393),30.9％ (430/1393) and 75.8％ (1056/1393),respectively.Diabetics with dyslipidemia had higher body mass index,waist circumference,blood pressure,plasma glucose and hemoglobin A1c.The prevalence of dyslipidemia in the overweight and uncontrolled-glucose group were 79.0％ (1678/2125),78.9％ (1756/2227),respectively.Logistic regression analysis showed that gender,age,body mass index and hemoglobin A1c were associated with dyslipidemia.Conclusions The prevalence of dyslipidemia in diabetic subjects in Beijing urban communities is high and less than one quarter patients take hypolipid agents.Age,body mass index and hemoglobin A1c are the risk factors of dyslipidemia in type 2 diabetic patients.
