Objective:To explore the effect of the interaction between plasma aluminum concentration and schooling year on cognitive function, it provides the basis for early identification of its damaging effect.Methods:From October to December, 2014, 1114 on-the-job aluminum exposed workers in a large aluminum factory in Shanxi Province were investigated. The plasma aluminum concentrations were measured by inductively coupled plasma-mass spectrometry (ICP-MS) as an internal exposure indicator. The subjects were divided into low, medium, and high aluminum exposure group based on the blood lead concentration levels. The general information was collected with a self-designed questionnaire, and their cognitive function was evaluated with the mini-mental state examination and the clock drawing test. The interaction between plasma aluminum concentration level and education level was analyzed by using unconditional logistic regression fitting multiplication model and cross analysis fitting addition model.Results:The average level of plasma aluminum of the subjects was 21.68 (10.51, 45.78) μg/L. The detection rate of cognitive impairment was 19.9%. The influencing factors of cognitive function were plasma aluminum concentration, age, education level and marital status, among which high schooling year, and being married were the protective factors (all P<0.05), plasma aluminum concentration, and age were the risk factors (all P<0.05) ; After adjusting the confounding factors, such as age, marital status, schooling year, income level, smoking, and drinking, logistic regression model and the multiple linear regression model showed that there was a dose response relationship between plasma aluminum concentration and cognitive impairment. With the increase of plasma aluminum concentration, the score gradually decreased, and the risk of cognitive impairment increased ( Ptrend<0.05) ; There were multiplicative interaction ( AOR=2.15, 95% CI: 1.10-4.19) and additive interaction ( RERI=5.38, 95% CI: 2.60-8.16; AP=0.65, 95% CI: 0.51-0.80; S=3.88, 95% CI: 2.00-7.56) between plasma aluminum concentration and low schooling year on cognitive function. Conclusion:There was a dose-response relationship between aluminum exposure and cognitive impairment. There was an interaction between aluminum exposure and low schooling year. When both of them worked together, the risk of cognitive impairment increases.

Objective To investigate the genetic causes of auditory neuropathy with optic atrophy in a family.Methods The proband's medical history and family history were inquired in detail,and relevant clinical examina-tions were performed to confirm the diagnosis of auditory neuropathy with optic atrophy,and the genetic pedigree of the family was drawn.Peripheral blood of proband(Ⅲ-7)was collected for whole exome sequencing,and the patho-genicity of the detected mutations were interpreted.Blood samples of proband's wife(Ⅲ-8),eldest daughter(Ⅳ-7),second daughter(Ⅳ-9)and son(Ⅳ-10)were tested for mutation sites by Sanger sequencing.Combined with clinical manifestations and examination results,the family was studied.Results The genetic pattern of this family was autosomal dominant.The proband showed decreased visual acuity at the age of 19,bilateral sensorineural deaf-ness at the age of 30,and decreased speech recognition rate.Among 20 members of the family of 5 generations,10(2 deceased)showed similar symptoms of hearing and visual impairment.Proband(Ⅲ-7),eldest daughter(Ⅳ-7)and son(Ⅳ-10)underwent relevant examination.Pure tone audiometry showed bilateral sensorineural deafness.ABR showed no response bilaterally.The 40 Hz AERP showed no response in both ears.OAE showed responses in some or all of the frequencies.No stapedial reflex was detected.The eye movement of Ⅲ-7 and Ⅳ-10 were reasona-ble in all directions,and color vision was normal.Ocular papilla atrophy was observed in different degrees in fundus examination.OCT showed thinning of optic disc nerve fibers in both eyes,and visual evoked potential showed pro-longed P100 wave peak.They were diagnosed as hereditary auditory neuropathy with optic atrophy.A mutation of the OPA1 gene c.1334G＞A(p.Arg445His,NM_015560.2)at a pathogenic locus on chromosome 3 was detected by whole exon detection in Ⅲ-7.The results of generation sequencing analysis showed that the OPA1 gene c.1334G＞A(p.Arg445His,NM_015560.2)mutation of chromosome 3 was also found in Ⅳ-7 and Ⅳ-10.Meanwhile,the gen-otypes of Ⅲ-8 and Ⅳ-9 were wild homozygous,that is,no mutation occurred.Conclusion The OPA1 c.1334G＞A(p.Arg445His,NM_015560.2)mutation site might be the pathogenic mutation in this family.

Objective:To investigate the association between hyperuricemia and the risk for stroke occurrence, as well as the mediating effect of hypertension on this association.Methods:In this study, the China Chronic Diseases and Nutrition Surveillance system in 2015 was used as baseline data. We identified hospital admissions for stroke using the electronic homepage of inpatient medical records from 2013-2020, and death data were obtained from the 2015-2020 National Mortality Surveillance System. A retrospective cohort was established after matching and linking the database. The Cox proportional hazard regression model was used to analyze the relationship between hyperuricemia and the risk of stroke and its subtypes. Restricted cubic spline analysis was conducted to examine the dose-response relationship between serum uric acid levels and the risk for stroke. Mediation analysis was performed to investigate the mediating effect of hypertension on the association between hyperuricemia and the risk for stroke and its subtypes. Subgroup analyses were conducted based on gender and age groups.Results:A total of 124 352 study subjects were included, with an accumulative follow-up time of 612 911.36 person-years. During the follow-up period, 4 638 cases of stroke were found, including 3 919 cases of ischemic stroke and 689 cases of hemorrhagic stroke. The incidence density of stroke was 756.72 per 100 000 person-years, 641.37 per 100 000 person-years for ischemic stroke, and 114.60 per 100 000 person-years for hemorrhagic stroke. Multivariable Cox proportional hazards regression models showed that after adjusting for covariates, compared to those without hyperuricemia, individuals with hyperuricemia had a 16% higher risk for stroke [hazard ratio ( HR)=1.16, 95% CI: 1.06-1.27], a 12% higher risk of ischemic stroke ( HR=1.12, 95% CI: 1.01-1.24), and a 39% higher risk of hemorrhagic stroke ( HR=1.39, 95% CI: 1.11-1.75). Mediation analysis showed that hypertension partially mediated the associations between hyperuricemia and the risk for stroke, ischemic stroke, and hemorrhagic stroke, with mediation proportions of 36.07%, 39.98%, and 25.34%, respectively. The mediating effect is pronounced in the male population and individuals below 65. Conclusion:Hyperuricemia is a risk factor for stroke, and hypertension partially mediates the effect of hyperuricemia on stroke.

Objective The characteristics of supramolecular"imprinting template"of volatile oil of Curcuma kwangsiensis and Curcuma phaeocaulis were analyzed and studied based on the supramolecular"qixi"theory of Chinese materia medica combined with chemometrics.Methods The volatile oil of C.kwangsiensis and C.phaeocaulis were extracted by steam distillation,and the fingerprint and composition information of each batch were obtained by GC-MS.Total statistical moment method was used to compare the imprinting characteristics of the"imprinting template"of C.kwangsiensis and C.phaeocaulis.The core index(CI)of each batch of essential oil of C.kwangsiensis and C.phaeocaulis was calculated,and the topological characteristics of types of"imprinting template"of C.kwangsiensis and C.phaeocaulis were compared by chemometrics.Results There was no significant difference in the extraction rate of volatile oil between C.kwangsiensis and C.phaeocaulis.The average values of total zero order moment(AUCT)were(1.907±0.177)×108,(1.979±0.413)×108 μV·s,respectively,showing that there was no significant difference in the total content of volatile oil between the two groups.The mean values of the total first order moment(MCRTT)were(30.969±0.962)and(33.198±0.409)min.The average value of total second order moment(VCRTT)was(56.176±11.368)and(43.891±4.113)min2,respectively,indicating that there were significant differences in the content ratio and species of volatile oils between the two groups.The similarity of total statistical moments of C.kwangsiensis and C.phaeocaulis was mostly lower than the defined value,indicating that the chemical composition and composition ratio of the volatile oil were different.Principal component analysis and orthogonal partial least squares discriminant analysis could obviously divide C.kwangsiensis and C.phaeocaulis into two categories.Through the analysis of P value and VIP value,the CI values of Xvp 4th order,Xvpc 5th order,Xvpc 6th order,Xvpc 7th order,Xvc 3rd order,Xvpc 4th order were the main difference values of C.kwangsiensis and C.phaeocaulis.Conclusion Through the characterization of"imprinting property"and"topological characteristics"of the supramolecular"imprinting template"and combining with chemometric analysis,it is possible to successfully distinguish C.kwangsiensis and C.phaeocaulis,and find the different CI values between two"imprinting templates".

Objective:To investigate the level and clinical significance of peripheral blood CD4 +T cell subpopulations in late-onset systemic lupus erythematosus (SLE) patients. Methods:This study included 260 SLE patients hospitalized in the Rheumatology and Immunology Department of the Second Hospital of Shanxi Medical University from January 2016 to December 2021: of whom 58 and 202 were late- (≥50 years) and adult-(18~49 years) onset patients. This study also included 160 subjeces as healthy controls(HCs), of whom 35 and 125 were Control Group 1 (≥50 years) and Control Group 2 (18~49 years). Peripheral blood CD4 +T lymphocyte subsets of these participants were assessed by flow cytometry. The clinical data of all patients and healthy controls (HCs)were recorded. The differences between the groups were analyzed by Mann-Whitney U test or χ2 test. Results:(1)The time of diagnosis of late-onset SLE was longer than that of adult-onset SLE [Median time: 5.0 (2.0, 24.0)months vs 3.0 (1.0, 7.3)months, Z=-3.13, P=0.002]. Compared with adult-onset SLE, the SLEDAI score of late-onset SLE was lower [12.0 (8.0, 15.2) vs 14.0 (10.0, 18.0), Z=-2.12, P=0.034]. Some manifestations occurred more frequently in late-onset SLE, such as weight loss, nausea, abdominal pain, cerebral infarction, interstitial pneumonitis, Sj?gren′s syndrome and infection. The manifestations of skin and mucos a occurred less frequently in late-onset SLE. (2)CD4 +T cell subpopulations: ①The absolute counts of Treg, Th17, Th1 and Th2 cells in the peripheral blood of patients with late-onset SLE were significantly lower than those of HCs [Treg: 10.94 (6.14, 19.23) vs 32.65 (28.07, 41.65), Z=-6.79, P<0.001; Th17: 3.43 (0.94, 5.64) vs 6.13 (3.77, 7.82), Z=-3.24, P=0.001; Th1: 36.02 (10.80, 76.38) vs 128.70(89.82, 159.89), Z=-5.29, P<0.001; Th2:3.56 (1.56, 6.06) vs 8.25 (4.69, 12.98), Z=-4.57, P<0.001]. The ratio of Th17/Treg cells was higher than that of HCs[0.28(0.13, 0.59) vs 0.17 (0.12, 0.28), Z=-2.38, P=0.017].②The absolute counts of Treg, Th17, Th1 and Th2 cells in peripheral blood of patients with adult-onset SLE were significantly lower than those of HCs [Treg: 10.28 (5.37, 17.04) vs.30.19 (21.20, 39.75), Z=-11.28, P<0.001; Th17: 3.44 (1.84, 6.14) vs 6.48 (4.23, 10.66), Z=-6.53, P<0.001; Th1: 29.59(15.14, 56.81) vs 90.75(42.67, 162.00), Z=-7.01, P<0.001; Th2: 2.74 (1.62, 4.77) vs 8.25 (4.75, 11.99), Z=-9.91, P<0.001]. The ratio of Th17/Treg was higher than that of HCs[0.35 (0.17, 0.65) vs 0.23(0.14, 0.37), Z=-3.89, P<0.001].③The ratios of Th17/Treg in patients with late-and adult-onset SLE were higher than those of HCs. The ratio of Th17/Treg was the highest in adult-onset SLE patients. Conclusion:Patients with late-onset SLE have reduced numbers of Treg cells and the immune imbalanced of Th17/Treg. However, the immune imbalance of Th17/Treg in late-onset SLE patients is milder than that in adult-onset SLE patients, which may be related to lower disease activity.
