Objective:To compare the test methods for aluminum content determination in vaccines by inductively coupled plasma-mass spectrometry(ICP-MS),inductively coupled plasma optical emission spectrometry(ICP-OES)and titration of the Chinese Pharmacopoeia 2020.Methods:The pre-treatment procedures,linearity,repeatability,accuracy,quantification limit,detection limit and sample determination results of the three methods were compared and analyzed by methodological verification and sample testing.Results:There was a good linear relationship of ICP-OES in the concentration range of 1-20μg·mL-1 aluminum content,r=0.9999.Aluminum content in 6 types of vaccines was in the range of 99％-104.6％,and RSDs were lower than 3％(n=9).There was a good linear relationship of ICP-MS in the concentration range of 2.5-80ng·mL-1(r=0.999).Aluminum content in 6 types of vaccines were in the range of 99.4％-108.9％,and RSDs were lower than 8％(n=9).There was no significant difference between the three methods in the determination of aluminum content in vaccines,and RSDs were lower than 10％.Conclusion:Both ICP-MS and ICP-OES methods can be used for the determination of alu-minum content in aluminum adjuvant vaccine.Both detection methods are simple,fast and accurate.ICP-OES has lower instrument costs and is easier to promote in the laboratory.

Population aging in China has led to an increase in the incidence of abdominal aortic aneurysm(AAA).AAA rupture is one of the most severe life-threatening diseases,with high mortality.The main histopathological features of AAA include elastin degradation,smooth muscle cell depletion,extracellular matrix digestion,and mural leukocyte accumulation.Clinically,drug therapy is still lacking,and open/endovascular repair remains the most effective treatment strategy for AAA management.Notably however,the detailed molecular mechanism of AAA remains unclear,representing an important bottleneck affecting the development of potential drug targets.Animal models are the most powerful tools for clarifying the pathogenesis of AAA,and although some medium-to-large laboratory animal models(e.g.,rabbits,guinea pigs,dogs,pigs)have been established for AAA studies,rodent models(mice and rats)are still the main models used in this field.Current method of inducing AAA include intra-infrarenal aortic infusion of elastase,subcutaneous infusion of angiotensin Ⅱ,periaortic calcium chloride painting,and decellularized aortic xenografting;however,AAA tends to stabilize in most models after ceasing pre-induced stimulation(medical or surgical),and there remains a need for ideal animal models that maintain continuous aortic dilation and even rupture.AAA animal models are helpful for elucidating the pathogenesis of AAA,screening new drug targets,and promoting clinical translation.This review aims to discuss the application of current AAA modeling method and their translational relevance.

Objective:To observe the clinical efficacy of back-Shu and front-Mu points combination needling on balance and walking function in patients after stroke and its mechanism. Methods:A total of 79 patients with post-stroke balance and walking dysfunction were randomly divided into a control group and an observation group.Both groups received conventional treatments such as dietary guidance and oral medications as well as rehabilitation training.On this basis,the control group was treated with additional conventional acupuncture,and the observation group was treated with additional back-Shu and front-Mu points combination needling.Both groups were treated for 4 consecutive weeks.The thickness of abdominal muscle group(transverse abdominal muscle,rectus abdominis,obliquus internus abdominis,and obliquus externus abdominis),the scores of Berg balance scale(BBS),Fugl-Meyer assessment(FMA),and functional ambulation categories(FAC),and walking velocity and stride were compared between the two groups. Results:During the trial,there was 1 dropout case in the control group and 4 dropout cases in the observation group.Before treatment,there were no statistical differences in the abdominal muscle group thickness,scores of BBS,FMA,and FAC,and walking velocity and stride between the two groups(P>0.05).After 4 weeks of treatment,the thickness of abdominal muscle groups,scores of BBS,FMA,and FAC,and walking velocity and stride in both groups were improved(P<0.01),and the observation group was superior to the control group(P<0.05). Conclusion:Both conventional acupuncture and back-Shu and front-Mu points combination needling are conducive to the improvement of balance and walking function in patients after stroke.The back-Shu and front-Mu points combination needling method has better curative efficacy.Strengthening the core muscle group strength may be one of the mechanisms of back-Shu and front-Mu points combination needling treatment.

Objective To evaluate the accuracy and reliability of tear film rupture time(TBUT)measurement in the diagnosis of dry eye in adolescents.Methods A total of 185 adolescents with dry eye treated in our hospital from September 2021 to September 2023 were selected as the observation group,and 20 healthy adolescents were selected as the control group.The accuracy and reliability evaluation of TBUT measurement in the diagnosis of dry eye in adolescents were analyzed.Results Among 185 patients,invasive TBUT detection detected 132 cases,the total detection rate was 71.35% ,non-invasive TBUT detection detected 160 cases,the total detection rate was 84.49% ,there was a statistical difference between groups(P＜0.05).Among the 185 patients,there were 128 cases of non-meibomian gland dysfunction and 57 cases of meibomian gland dysfunction.The detection rate of non-meibomian gland dysfunction by invasive TBUT detection was 41.62% ,and the detection rate of meibomian gland dysfunction was 29.73% ,and the detection rate of non-invasive TBUT detection was 63.24% ,and the detection rate of meibomian gland dysfunction was 23.24% .There was statistical difference between groups(P＜0.05).Compared with control group,TBUT,initial TBUT and average TBUT in observation group were significantly decreased(P＜0.05).Compared with group A,TBUT,first time TBUT and average TBUT in group B were significantly decreased,with statistical difference between groups(P＜0.05).The sensitivity,specificity and AUC of invasive TBUT detection were 72.49% ,75.88% and 0.762,and the sensitivity,specificity and area under the curve(AUC)of non-invasive TBUT detection were 87.24% ,90.05% and 0.926.Conclusion TBUT has diagnostic value in the diagnosis of juvenile dry eye,and compared with invasive TBUT,non-invasive TBUT is more accurate and reliable.

Objective To investigate and evaluate the nutrition status in serum 25-hydroxy vitamin D[25(OH)D]levels of 0～12 years old children in Xi'an.Methods A total of 2 670 patients aged 0～12 years old who underwent routine physical examinations in Children's Health Department of the Second Hospital of Air Force Medical University were selected from March 2020 to July 2023,and the 25(OH)D data of these patients were conducted in retrospective analysis.The nutritional status of vitamin D in these children of different genders,ages and seasons were also analyzed.Results ①This study included 2 670 children aged 0～12 years old in Xi'an,with the average level of serum 25(OH)D was 40.80±18.00 ng/ml.Among them,38 cases(1.42%)had serum 25(OH)D deficiency,333 cases(12.47%)had serum 25(OH)D insufficience,and 2 299 cases(86.11%)had sufficient serum 25(OH)D.②There was a statistically significant difference in serum 25(OH)D levels among different age groups(H=1 524.23,P=0.000).The group aged 1～<4 has the highest value of 52.51±13.57 ng/ml,while the group aged 8～12 has the lowest value of 21.65±6.75 ng/ml.③The levels of serum 25(OH)D in summer(39.44±17.46 ng/ml)were lower than those in spring(41.96±17.76 ng/ml)and autumn(42.71±18.15 ng/ml),with statistical significant differences(Z=101.57,-134.06,all P<0.01).However,the deficiency and inadequate rate of serum 25(OH)D in winter(18.95%)was higher than those in spring,summer and autumn(13.52%,12.75%,12.36%),with statistical significant differences(χ2=14.32,P=0.026).④There was no statistically significant difference in serum 25(OH)D levels between genders(H=0.933,P=0.351).However,the deficiency and inadequate rate of serum 25(OH)D in boys(12.51%)was lower than that in girls(15.46%),and the difference was statistically significant(χ2=9.257,P=0.010).Conclusion The nutritional status of serum 25(OH)D in children aged 0～12 years in Xi'an area is comparatively fine,and it is necessary to strengthen the intake and supplementation of vitamin D in over 3 years old children.

Objective To analyze the relationship of the volume of 87 brain regions with postnatal age and neurobehavior in full-term neonates.Methods A total of 75 full-term newborns[gestational age(39.38±1.22)weeks;male/female(51/24);postnatal age(11.11±6.67)days]without abnormalities on brain MRI(three-dimensional T1-weighted imaging,3D T1WI)at our hospital between November 2010 and September 2017 were retrospectively included.Based on the template of 87 brain regions,the neonatal brains were divided into 87 brain regions and their volumes were calculated by using V-shape Bottleneck network(VB-Net)deep learning segmentation technique,Pearson partial correlation and regression analysis were used to explore the relationship of the volume of each brain region with postnatal age and neurobehavioral scores.Results After adjusting for gestational age,birth weight,head circumference,body length and sex,66.7％of the regional brain volumes(58/87 brain regions)significantly increased with the postnatal age(correlation coefficient r:0.2-0.7,P＜0.05).The volumes of gray matter in bilateral lentiform nucleus,left caudate nucleus,right occipital lobe,right inferior temporal lobe,and bilateral anterior temporal lobe strongly correlated with the postnatal age(r＞0.50,P＜0.05).The gray matter volume of the right occipital lobe linearly increased with age(slope:100.67),and was positively correlated with behavioral scores(r=0.324,P＜0.01).Conclusion Most of regional brain volumes increase with the postnatal age during the neonatal period,and the fastest growth occurs in primary sensorimotor-related brain regions,presenting the spatial heterogeneity.Partial brain region grows with the development of behavioral ability.

Objective To explore the effect of exposure to noise of 3.0T magnetic resonance imaging(MRI)on children's cochlear function.Methods We prospectively recruited 72 children who underwent cranial MRI examination at our hospital from May to November 2018;3M earplugs and sponge mats were used for hearing protection during MRI scanning.Noise level(dBA)of each MRI sequence was detected with a nonmagnetic microphone and a sound level meter.Distortion product otoacoustic emissions(DPOAE)test at 2-7 kHz was performed 24 hours before and 30 minutes after the MRI examination.Paired t-test or Wilcoxon signed-rank test was used to analyze differences in DPOAE amplitude before and after the MRI examination.Results The average noise level of MRI measured in the study was(107.7±3.92)dBA.Compared with that before the MRI examination,the DPOAE amplitude(dB)changed little after the MRI examination;the range of amplitude differences in each age group was as follows:left ear(-0.24-1.10)and right ear(-0.24-0.74)in the 0-1 year-old group;left ear(-0.07-0.59)and right ear(-0.57-0.75)in the 2-5 year-old group;left ear(-0.36-0.44)and right ear(-0.30-0.57)in the 6-12 year-old group.No statistically significant difference was found(correction P＞0.05).Conclusion No potential impact of 3.0T MRI noise on children's cochlear function was observed under routine hearing protection.

AIM:To assess the evolving burden of cataracts in China from 1990 to 2019.METHODS: Data on disease burden related to cataracts in China were retrieved from the Global Burden of Disease(GBD)2019 study based on large public databases. Utilizing data from the GBD 2019 study, we extracted information on cataract-related disease burden in China from extensive public databases. Analysis of prevalence and disability-adjusted life years(DALYs)associated with cataracts in China was conducted based on GBD 2019 findings. The variable characteristics of age-standardized prevalence rates(ASPR)and age-standardized DALYs rates(ASDR)in China and its neighboring countries were also explored.RESULTS: Between 1990 and 2019, the number of prevalent cases of blindness and vision loss caused by cataracts in China increased by 223.54%, and the corresponding DALYs raised by 142.14%. Over the past 30 years, females exhibited higher age-standardized prevalence and DALYs rates compared to males. Meanwhile, individuals aged 65 to 84 years were found to be more susceptible to cataracts than other age groups. Compared with neighboring countries, China ranked from the 9th position in 1990(867.09, 95%UI: 761.36 to 975.42, per 100 000 population)to the 11th in 2019(991.56, 95%UI: 861.52 to 1131.04, per 100 000 population)in ASPR, while from the 9th in 1990(65.85, 95%UI: 46.39 to 89.41, per 100 000 population)to the 10th position in 2019(59.16, 95%UI: 41.70 to 80.15, per 100 000 population)in ASDR. However, on a global scale, China maintained relatively low ASDR and ASPR for cataracts in 2019.CONCLUSION: The study highlights a substantial rise in the prevalence and DALYs associated with blindness and vision loss due to cataracts from 1990 to 2019 in China, and underscores the urgent need for increased early screening of cataracts, particularly among the elderly and females.
