Objective To explore the optimal duration of long-term mild hypothermia(MHT)for traumatic brain injury(TBI)in rats,and observe its effect on intracranial pressure(ICP)and neurological function.Methods Forty-eight healthy adult male SD rats were divided into the normal temperature treatment(NT)group,the MHT4 h group,the MHT24 h group and the MHT48 h group by random number table method,with twelve rats in each group.The TBI model of rats was prepared by electronic controllable cortical injury device,and ICP monitoring probe was implanted.After modeling,the NT group was treated with normal temperature(37℃),and the other groups were treated with low temperature(33.0±1.0)℃for 4 h,24 h and 48 h,respectively.ICP was monitored and brain water content(BWC)was calculated after MHT treatment in each group.Blood-brain barrier permeability was determined by Evansland(EB)staining.The expression of 5-bromodeoxyuracil nucleoside(BrdU),neuronal nuclear antigen antibody(NeuN)and leukocyte differentiation antigen 86(CD86)positive cells were detected by immunofluorescence staining.The expressions of B-cell lymphoma-2(Bcl-2),Bcl-2 associated X protein(Bax),inducable nitric oxide synthase(iNOS),interleukin(IL)-10 and arginase 1(Arg-1)were detected by Western blot assay.Results Compared with the NT group,levels of BWC,ICP,EB,and CD86 positive cells,Bax and iNOS expression levels were decreased in the MHT4 h group,the MHT24 h group and the MHT48 h group,and the number of BrdU positive cells and BrdU/NeuN double-labeled positive cells were increased in hippocampus.The expression levels of Bcl-2,IL-10 and Arg-1 were increased(P＜0.01).Compared with the MHT24 h group,levels of BWC,ICP and EB,and CD86 positive cells,Bax and iNOS expression were decreased,and the number of BrdU positive cells and BrdU/NeuN double-labeled positive cells were increased in the MHT48 h group,while levels of Bcl-2,IL-10 and Arg-1 expression were increased(P＜0.01).Conclusion Long-term MHT can promote the proliferation and differentiation of neurons,inhibit apoptosis and reduce inflammation by suppressing ICP rebound,further promoting neuroprotection after TBI.
Résumé
BACKGROUND:Myocardial infarction is one of the most serious cardiovascular diseases at present,and the existing clinical treatment options such as thrombolytic therapy,percutaneous coronary intervention and coronary artery bypass grafting cannot fully restore the myocardial damage caused by ischemia.Stem cell-derived exosomes for the treatment of myocardial infarction have been a hot research topic in recent years,but the low yield of natural-derived exosomes,the difficulty and time consuming nature of obtaining them,and the poor homing effect have limited their clinical application.In this context,the construction of artificial exosomes as an alternative to natural exosomes has become an effective strategy to solve the above problems. OBJECTIVE:To expound the research status of artificial exosomes in the treatment of myocardial infarction,and classify them into two design modes:semi-artificial and full-artificial,and discuss the research progress and problems of the two modes,finally,make the evaluation and prospect of its clinical application in the future. METHODS:PubMed and CNKI were searched for relevant articles with"artificial exosomes,myocardial infarction,engineering"in Chinese,and"artificial exosome,hybrid exosome,myocardial infarction,nanoparticle,drug delivery system"in English.The focus of the search was from January 2017 to December 2022,and some of the classic forward literature was included.A preliminary selection was conducted through reading titles and abstracts.Repetitive studies,low-quality journals and irrelevant articles were excluded.Finally,73 articles were included for review. RESULTS AND CONCLUSION:(1)By semi-artificially modifying exosomes,whether it is the modification of targeting peptides,hybridization of biofilms or the assistance of magnetic substances,traditional exosome therapies with insufficient targeting and low retention rate and easy to be cleared by the reticuloendothelial system have improved the efficiency of traditional exosome therapy for myocardial infarction.However,these strategies have problems such as unclear modification efficiency,medical ethics,and biotoxicity.(2)Fully artificial bionic exosomes have a higher degree of design freedom compared to exosome modification,which can solve the problems of high extraction and storage difficulties of exosomes of natural origin and limitations of large-scale production;however,this artificial exosome strategy still lacks reliable preclinical data support and biosafety testing,and has not yet formed a standardized process required for large-scale production;therefore,before applying to the clinic,the artificial exosome solution as an alternative to natural exosomes still needs continuous in-depth research by researchers.

BACKGROUND:Gait is one of the optimal indicators of functional status in older adults.Gait parameters are associated with adverse health outcomes in older adults. OBJECTIVE:To summarize and compare the practical value of gait parameters,and to review the progress of research on spatio-temporal parameters and the risk of adverse health outcomes in older adults. METHODS:PubMed,Web of Science,and CNKI were searched for relevant literature published from January 2010 to June 2023 using the search terms of"gait speed,walking speed,step length,cadence,step frequency,step time,walking base,aged and elderly"in English and Chinese,respectively.A total of 52 papers were finally included for the systematic review. RESULTS AND CONCLUSION:Currently,researchers have focused on three basic temporal-spatial parameters,namely,step speed,step length and step frequency,to explore their association with adverse health outcomes in older adults.Reduced gait speed in older adults may increase the risk of falls,all-cause mortality,and may be an independent predictor of all-cause mortality.Older adults with slow gait speed are at higher risk of cognitive decline,and may be the preferred gait parameter in assessing cognitive impairment in older adults.Older adults with slow gait speed are more likely to have debilitating or common chronic illnesses,and are at higher risk of hospitalization and public care.Step length is positively correlated with individual height and lower limb length,but age-induced shortening of step length is not related to height or lower limb length,and shortening of step length reflects reduced physical function in older adults,and shortening of step length is a risk factor for falls and cognitive decline in older adults.Stride frequency is often used as a measure of exercise intensity,and a stride frequency of≥100 steps/minute is predictive of all-cause mortality,and slowing of step frequency may lead to a higher risk of falls,hospitalization and all-cause mortality in older adults.Changes in gait parameters are closely related to the level of physical fitness in older adults,and there may be a bidirectional relationship between the two.The results of the study will provide a theoretical basis for further improving risk screening in clinical populations,refining health risk assessment in the elderly,improving health protection and promoting active health in the elderly.

Objective:To study the distribution and changes of dopamine transporter (DAT) in guinea pig eyes under different light patterns.Methods:Thirty-six 3-week-old white ordinary-grade guinea pigs were randomly selected and divided into groups of 10 000 lx, 5 000 lx, and 500 lx, with 12 guinea pigs in each group exposed to strong light, medium strong light, and normal light, respectively.Each group was randomly divided into 3 subgroups, with 4 guinea pigs in each subgroup.The 3 subgroups of 500 lx group received light exposure for 5, 20, and 40 minutes, respectively.The 3 subgroups of 5 000 lx group received light exposure for 2, 4, and 40 minutes, respectively.The 3 subgroups of 10 000 lx group received light exposure for 2, 5, and 20 minutes, respectively.After light treatment, each group of guinea pigs was injected with 99mTc-TRODAT-1 for SPECT DAT imaging, and image data were collected by Micro-SPECT.The region of interest (ROI) of guinea pig retinas was analyzed using Micro-CT software.The counts of ROI were expressed as Sum, which reflected the relative distribution or density of DAT.The DAT density between experimental and control eyes of guinea pigs after light exposure, the differences in DAT density between guinea pig eyes under different light intensities, the differences in DAT density between guinea pig eyes after different light durations, and the cumulative and interactive effects of light intensity and light duration on DAT aggregation in guinea pigs were compared.Another 3 guinea pigs were selected, and after light exposure, the 3 guinea pigs' eyes underwent continuous image acquisition for 6 hours at 20-minute intervals, and 18 images per guinea pig were acquired to analyze the trend of DAT density in guinea pig eyes over time.This study was approved by the Ethics Committee of Shanghai General Hospital (No.2020SQ196). Results:The DAT density (Sum value) of experimental eyes at 500, 5 000, and 10 000 lx were 5 598.97±3 159.38, 8 636.78±2 503.16, and 7 407.39±2 053.41, respectively, significantly higher than 4 388.89±2 902.90, 5 981.92±3 057.44, and 5 091.32±2 039.36 of control eyes ( t=5.31, 4.69, 11.80; all at P<0.001). At 500 lx, there was a statistically significant difference in DAT density between the experimental and control eyes of guinea pigs at different light exposure durations ( F=14.01, P<0.01), while no significant difference was found at other light intensities at different light exposure durations (both at P>0.05). When the light exposure time was 5 minutes, the difference in DAT density between the experimental and control eyes of guinea pigs was significantly greater in the 10 000 lx group than in the 500 lx group ( t=-13.22, P<0.001). There was no statistically significant difference between different groups at other light exposure durations (all at P>0.05). No cumulative or interactive effects of light intensity and light duration were found on the differences in DAT density (all at P>0.05). Continuous scanning after illumination showed that DAT density in guinea pig retinas first increased to a peak over time and then gradually returned to normal values. Conclusions:Light, even under moderate or normal light levels, can cause an increase in the secretion of DAT in the retina and stimulate the production of DAT.Light intensity and duration have no cumulative or interactive effects on the distribution and density of retinal DAT.

BACKGROUND@#There has been minimal research on the role of benevolent childhood experiences (BCEs) and how such events may offer protection from the insidious effects of adverse childhood experiences (ACEs) or later in life.@*OBJECTIVES@#This research aims to learn how BCEs and ACEs interact to affect adolescents' psychological distress.@*METHODS@#Cross-sectional survey was conducted in three cities (Xuzhou, Nanjing, and Wuhan) in China from March 2021 to May 2021. Latent class analysis (LCA) was used to classify the patterns of ACEs and BCEs. We adopted hierarchical multivariable regression to examine the influences of ACEs and BCEs on depression and suicidal ideation.@*RESULTS@#To explore the relationship between childhood experience and suicidal ideation and depression, LCA revealed three patterns of ACEs: (1) emotional abuse (10.57%); (2) high ACEs (0.55%); and (3) low ACEs classes (88.88%). Adolescents with emotional abuse (depression: OR = 3.82, 95%CI = 2.80-5.22, P < 0.001; suicidal ideation: OR = 5.766, 95%CI = 3.97-8.38, P < 0.001) and high ACEs class (suicidal ideation: OR = 5.93, 95%CI = 1.19-29.66, P < 0.05) had an increased risk of psychological distress (reference: low ACEs). LCA revealed four patterns of BCEs: (1) relationship support (14.54%); (2) low BCEs (4.85%); (3) high BCEs (55.34%); and (4) high quality of life classes (25.28%). Adolescents with a high quality of life (depression: OR = 0.09, 95%CI = 0.05-0.16, P < 0.001; suicidal ideation: OR = 0.22, 95%CI = 0.12-0.40, P < 0.001) and high BCEs (depression: OR = 0.05, 95%CI = 0.03-0.09, P < 0.001; suicidal ideation: OR = 0.15, 95%CI = 0.09-0.26, P < 0.001) protected the mental health of adolescents (reference: low BCEs).@*CONCLUSIONS@#High ACEs and emotional abuse classes were significantly associated with poorer mental health symptoms, including suicidal ideation and depression. In contrast, high BCEs and high quality of life classes were associated with better mental health. These findings point out that it is more necessary to identify and support victims of ACEs, and it is urgent to increase BCEs in early childhood.

Objective:To predict the risk of major adverse cardiovascular events (MACE) in acute coronary syndrome (ACS) patients with Subclinical thyroid function decline through exploration of free triiodothyronine (FT3), cardiac troponin I (cTnI), and N-terminal pro B-type natriuretic peptide (NT-proBNP) .Methods:A retrospective analysis was conducted on medical records of 125 ACS patients with Subclinical thyroid function decline to the Second People’s Hospital of Hefei City from Jan. 2020 to Mar. 2022. On the second day of hospitalization, fasting blood samples were collected from the patients. The levels of cTnI and NT-proBNP were measured using an electrochemiluminescence assay, while the level of FT3 was measured using a radioimmunoassay. The patients were followed up for 3 months to observe and record the occurrence of MACE. Based on the outcomes of MACE, the patients were divided into two groups: the adverse prognosis group and the good prognosis group. Logistic multivariate regression analysis was performed to identify the factors influencing the occurrence of MACE in ACS patients, and the predictive value of serum cTnI, NT-proBNP, and FT3 for MACE occurrence in ACS patients was evaluated.Results:Among the 125 ACS patients with Subclinical thyroid function decline, the incidence of MACE was 36 cases, with an incidence rate of 28.80%. Age ( OR=4.067, 95% CI: 1.856-10.231), hypertension ( OR=4.651, 95% CI: 1.942-9.779), diabetes ( OR=4.358, 95% CI: 1.887-10.051), coronary artery disease involving ≥3 vessels ( OR=4.047, 95% CI: 1.900-9.994), total cholesterol (TC) ( OR=4.100, 95% CI: 1.776-9.462), triglycerides (TG) ( OR=4.162, 95% CI: 1.558 - 11.114), low-density lipoprotein cholesterol (LDL-C) ( OR=3.428, 95% CI:1.642-8.743), serum cTnI ( OR=4.545, 95% CI: 1.987-10.394), and NT-proBNP ( OR=4.660, 95% CI: 2.045-10.617) were identified as risk factors for MACE occurrence ( P<0.05), while serum FT3 ( OR=0.275, 95% CI: 0.119-0.631) was considered a protective factor against MACE occurrence ( P<0.05). The individual and combined predictive values (area under the curve) of serum cTnI, NT-proBNP, and FT3 for MACE occurrence in ACS patients were 0.754, 0.738, 0.741, and 0.829, respectively. Conclusion:Serum cTnI, NT-proBNP, FT3 are closely related to the risk of MACE in patients with acute coronary syndrome with Subclinical thyroid function decline, and have high predic-tive power for the risk of mace.

Objective·To explore the association between high myopia and life quality among children.Methods·Cross-sectional study method was adopted in this study.Highly myopic children aged 4-10 from 16 districts in Shanghai were enrolled through Shanghai Child and Adolescent Large-scale Eye Study-High Myopia Registration Study.Baseline data for spherical equivalent after cycloplegia and questionnaire data in 2020 were collected.Emmetropic children aged 4-10 from 16 kindergartens and elementary schools in Jing'an District and Pudong New Area were enrolled.The uncorrected visual acuity,corrected visual acuity and spherical equivalent without cycloplegia were measured through myopia screening in schools,and the questionnaire on quality of life was filled out.Quality of life was measured by the Strengths and Difficulties Questionnaire(SDQ)and EuroQol Five Dimensions Questionnaire Visual Analogue Scale(EQ-VAS).After describing and testing the differences in variable distributions between the highly myopic children group and the emmetropic children group,the differences in life quality between the two groups,and the association between spherical equivalent and life quality scores of the highly myopic children were examined by a linear regression model.Results·A total of 193 children with high myopia and 209 children with emmetropia were enrolled.There were statistically significant differences in age[(9.58±0.94)years vs(7.63±1.50)years,P＜0.001]and gender distribution(46.6％males vs 62.7％males,P=0.00l)between the highly myopic children and emmetropic children.After adjusting for age and gender,it was found that there was no statistically significant difference in SDQ score between the highly myopic children and emmetropic children(β=0.313,95％CI-0.723-1.349,P=0.553),but the EQ-VAS score in the highly myopic children was lower than that in the emmetropic children(β=-3.805,95％CI-6.593--1.017,P=0.008).There was no significant relationship between spherical equivalent and SDQ score(β=0.297,95％CI-0.035-0.628,P=0.079)and EQ-VAS score(β=0.579,95％CI-0.330-1.489,P=0.21 1)in the highly myopic children.Conclusion·In children with high myopia,self-evaluated overall health status reflected by EQ-VAS score is poorer compared with that in children with emmetropia.However,the EQ-VAS score is not associated with the degree of high myopia.
Résumé
Systemic lupus erythematosus (SLE) is a serious autoimmune disease that affects multiple systems and organs throughout the body. Thrombotic microangiopathy (TMA) is a rare clinical syndrome that can lead to multiple organ dysfunction and even threaten life. Clinically, SLE patients with TMA are relatively rare, especially in children, but the mortality of SLE patients with TMA is significantly increased. The article reports 2 cases of successful remission of SLE complicated with TMA after treatment with eculizumab, and discusses the diagnosis, clinical manifestations and treatment of SLE complicated with TMA in children, so as to provide clinical basis for the diagnosis and treatment of SLE complicated with TMA in children.

Objective:To explore the application of sound thinking combined with Sandwich teaching in oncology nursing practice teaching.Methods:A total of 68 nursing students who were interns in the Department of Oncology, The First Affiliated Hospital of Air Force Medical University from 2020 to 2021 were included in the study, and they were divided into a control group ( n=34) and an observation group ( n=34). The control group took routine teaching for interns, while the observation group took sound thinking combined with Sandwich teaching. The examination results, critical thinking abilities, and the evaluation of nursing teaching effectiveness of the two groups of nursing interns were evaluated. SPSS 22.0 was used for Chi-square test and t-test. Results:The examination scores of nursing students in the observation group were higher than those in the control group ( t=3.44, 2.87, 3.45, P<0.05). Compared with those before training, the scores of critical thinking ability of nursing interns in both groups increased after the training, and the observation group was better than the control group ( t=0.180, 3.64, 0.61, 2.92, 0.31, 2.74, 0.45, 2.65, 0.25, 3.58, 1.16, 2.85, 0.36, 3.20, 0.33, 2.38, P<0.05). The scores of autonomous learning ability, communication and collaboration ability, independent thinking ability, clinical reasoning ability, and problem-analyzing and -solving ability in the observation group were higher than those in the control group ( t=2.82, 3.46, 2.68, 3.29, 2.44, P<0.05). Conclusion:Combining sound thinking with Sandwich teaching in nursing clinical practice teaching in department of oncology can improve the examination scores of nursing students, improve their critical thinking abilities, and enable them to give a high evaluation of nursing teaching effectiveness.
Résumé
Objective:To explore the prognosis of umbilical cord cysts in fetuses with structural abnormalities diagnosed by prenatal ultrasonography.Methods:This retrospective study involved 109 cases of umbilical cord cysts diagnosed by ultrasound at Beijing Obstetrics and Gynecology Hospital from January 2016 to December 2020. According to the ultrasound findings, these cases were divided into the isolated umbilical cord cyst, umbilical cord cyst with soft ultrasound markers, and umbilical cord cyst with fetal malformation groups. Chi-square was performed for statistical analysis to compare the prognosis. Results:(1) Among 109 cases of umbilical cord cysts, 55 cases (50.5%) were isolated, 20 (18.3%) were complicated by soft ultrasound markers, and 34 (31.2%) cases were complicated by fetal malformation. After excluding two cases of multiple cysts at different locations, the incidence of umbilical cord cysts at the placental end, free segment, and fetal terminal with other ultrasound abnormalities in the remaining 107 cases increased sequentially [27.5% (14/51), 10/17, and 76.9% (30/39), χ2=22.20, P<0.001]. The incidence of umbilical cord cysts with other ultrasound abnormalities at the fetal end was higher than at the placental end ( χ2=21.65, P<0.001). (2) A total of 60 fetal malformations were detected, dominated by fetal ventricular septal defect, omphalocele, giant bladder, fetal edema, and nuchal cystic hygroma, et al., mainly involving the cardiovascular system, urogenital system, anterior abdominal wall, and skeletal system. (3) Eighty-nine cases were followed up to the end of the pregnancy, and 21 (23.6%) of them had adverse outcomes. The prognoses of isolated umbilical cord cyst cases were all good. Two pregnancies (2/18) were terminated in the umbilical cord cyst with ultrasound soft markers group. In the group of umbilical cord cyst with fetal malformation, 19 pregnancies (19/26, 73.1%) had adverse outcomes, including pregnancy termination, intrauterine fetal demise, and perinatal death. Conclusions:The prognosis of isolated umbilical cord cysts is generally good. The umbilical cord cyst complicated by soft ultrasound marker and fetal malformation can have adverse outcomes, while conditions might be worse in those with fetal malformation. When an umbilical cord cyst is revealed, a systematical examination is recommended to identify whether it is combined with other ultrasound abnormalities.
