OBJECTIVE: To explore the relationship between the geriatric nutritional risk index (GNRI) and cognitive function. METHODS: A cross-sectional study method was conducted. People aged ≥ 60 years from the National Health and Nutrition Examination Survey (NHANES) databases from 1999 to 2002 and 2011 to 2014 were included as study subjects. The participants were divided into three groups based on their GNRI scores: a medium-high risk group (82 ≤ GNRI < 92), a low risk group (92 ≤ GNRI < 98), and a no-risk group (GNRI ≥ 98). Demographic characteristics (gender, age, race, education), chronic diseases [chronic bronchitis, emphysema, thyroid problems, coronary heart disease, angina pectoris, stroke, hypertension, diabetes mellitus, and depression score on the patient health questionnaire (PHQ-9)], lifestyle habits (history of smoking, hours of sleep), etc., were collected. Cognitive function was assessed using the consortium to establish a registry for Alzheimer's disease word learning subtest (CERAD-WL), animal fluency test (AFT), and digit symbol substitution test (DSST) for the 2011-2014 data, while only the DSST was used for the 1999-2002 data. Differences in the above information among the GNRI cohorts were compared. Factors affecting cognitive function in the population were analyzed using multifactorial Logistic regression. RESULTS: 2 653 participants from 2011 to 2014 and 2 380 participants from 1999 to 2002 were enrolled, with a total of 5 033 participants in the study. There were statistically significant differences in age, stroke, diabetes mellitus, DSST score, AFT score, CERAD score test 1 recall (Cst1), and CERAD score test 2 recall (Cst2) among the GNRI groups. Multifactorial Logistic regression analysis of data from 2011 to 2014 showed that in model 3 (DSST score, age, gender, race, marriage, education, hours of sleep, history of smoking, emphysema, thyroid problems, chronic bronchitis, coronary heart disease, angina pectoris, hypertension, diabetes mellitus, depression score on the PHQ-9, and stroke) adjusted for all covariates, GNRI was a protective factor for DSST [odds ratio (OR) = 1.03, 95% confidence interval (95%CI) was 1.00 to 1.05, P = 0.03]; Logistic regression analyse for 1999 to 2002 and 2011 to 2014 showed a significant association even after adjustment for covariates (OR = 1.02, 95%CI was 1.00 to 1.03, P = 0.02). Subgroup Logistic regression analyses of the total population from 2011 to 2014 showed a significant association between GNRI and DSST scores (OR = 1.02, 95%CI was 1.01 to 1.03, P < 0.001), with significant associations in the age subgroups of 60 to 64 years old, across gender, non-Hispanic Whites and Blacks, by education, and by marital status associations were significant (all P < 0.05). Subgroup Logistic regression analyse of the total populations from 1999 to 2002 and 2011 to 2014 showed a significant association between the GNRI and DSST score (OR = 1.01, 95%CI was 1.01 to 1.02, P < 0.001), but did not show a significant year difference (interaction P = 0.503), and the newly found in the smoking population the association was also more significant (P < 0.01). CONCLUSION The GNRI correlates with the presence of cognitive functions related to processing speed, sustained attention, and executive function, and may be able to serve as an indicator for the assessment or prediction of related cognitive functions.

Objective:To explore the morphological characteristics of the corpus callosum (CC) in patients with unilateral medial temporal lobe epilepsy (mTLE) with hippocampal sclerosis (HS), and their correlation with hippocampal volume and clinical indicators.Methods:This was a cross-sectional study. Clinical (age of onset, disease duration, seizure frequency, seizure duration, etc.) and imaging data of 44 patients mTLE with unilateral HS confirmed by postoperative pathology and 42 healthy controls (HCs) recruited at West China Hospital of Sichuan University from June 2017 to May 2023 were analyzed retrospectively. Among the 44 patients, 19 had left-sided HS and 25 had right-sided HS. All subjects underwent high-resolution 3D T 1WI. Hippocampal volumes were obtained using FreeSurfer. ART was used to measure the morphological parameters of the CC for each participant, including total CC area, volume, perimeter, length, thickness, circularity, and the area of seven CC subregions defined by Witelson: rostrum, genu, body, anterior midbody, posterior midbody, isthmus and splenium. Differences in these metrics between two or three groups were compared using independent samples t-test or one-way ANOVA. Pearson or Spearman correlation analysis was used to observe the correlation between morphological features of the CC and hippocampal volume and other clinical indicators in patients with mTLE with unilateral HS. Results:Compared with HCs, patients with mTLE with unilateral HS had significantly reduced total CC area, CC circularity, as well as the area and thickness of the genu, anterior midbody, posterior midbody, isthmus, splenium, and the area of the rostrum ( P<0.05). Significant differences were observed in the total area, circularity, and subregional areas (genu, rostrum, anterior midbody, posterior midbody, splenium), as well as thickness (genu, anterior midbody, posterior midbody, isthmus) of the CC among mTLE with left-sided HS, mTLE with right-sided HS, and HCs ( P<0.05). When compared to HCs, the total area of the CC, circularity and the areas of the genu, rostrum, anterior midbody, posterior midbody, and splenium, and the thicknesses of the genu, anterior midbody, posterior midbody, and isthmus of the CC were significantly reduced in patients with mTLE with right-sided HS ( P<0.05), and the thicknesses of the midbody and isthmus of the CC were significantly reduced in patients with mTLE with left-sided HS compared to HCs ( P<0.05), and the two-by-two comparison of the rest of the indicators did not show statistically significant differences ( P>0.05). Correlation analysis showed that some morphological abnormalities in the CC in mTLE with unilateral HS patients were significantly correlated with age of onset, disease duration, seizure frequency, seizure duration, and hippocampal volume. Conclusions:mTLE with unilateral HS patients can exhibit morphological abnormalities in the CC, particularly in those with right-sided lesions. These abnormalities are significantly associated with seizure-related factors and hippocampal atrophy.

ObjectiveTo observe the effect of gastrodin on the steroid regulatory element-binding protein 1c （SREBP1c） signaling pathway in high-fat high-cholesterol diet （HFHC）-induced mice and explore the mechanism of gastrodin in the treatment of non-alcoholic fatty liver disease （NAFLD）. MethodEight-week-old male C57BL/6J mice were used in vivo and divided into the following four groups， with six mice in each group： normal group， gastrodin group （50 mg·kg^-1）， model group， and model + gastrodin group （50 mg·kg^-1）. NAFLD model was established by feeding mice with HFHC for four weeks， and the mice were euthanized and the liver tissues were collected after four weeks. In vitro experiments were performed using Huh7 cells which were divided into five groups， and induced with free fatty acids （FFA， 200 μmol·L^-1， oleic acid-palmitic acid 2∶1） to establish an NAFLD cell model. After 24 h， different concentrations of gastrodin （0， 5， 10， 20， and 40 μmol·L^-1） were added to each group and cultured for another 24 h. Oil red O staining was used to detect lipid accumulation in mouse liver and Huh7 cells. Hematoxylin-eosin （HE） staining was used to observe pathological changes in liver tissue. Levels of serum total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C）， and triglycerides （TG） were measured using an automatic biochemical analyzer. Relevant assay kits were used to detect liver TC， TG， and FFA levels. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the expression of lipid synthesis-related proteins fatty acid synthase （FASN）， acetyl-CoA carboxylase 1 （ACC1）， and stearoyl-CoA desaturase 1 （SCD1）. ResultCompared with the normal group， the model group showed significantly increased serum TC， LDL-C， and TG levels （P<0.01）， liver TC， TG， and FFA levels （P<0.01）， increased lipid accumulation in Huh7 cells （P<0.01）， and significantly increased expression levels of lipid synthesis-related genes SREBP1c， FASN， ACC1， and SCD1 in mice and Huh7 cells （P<0.01）. Compared with the model group， after gastrodin treatment， the serum TC， LDL-C， and TG levels in mice significantly decreased （P<0.05， P<0.01）， the severity of fatty liver disease improved significantly， liver TC， TG， and FFA levels decreased significantly （P<0.05， P<0.01）， lipid accumulation in Huh7 cells decreased significantly （P<0.05， P<0.01）， the expression levels of lipid synthesis-related genes SREBP1c， FASN， ACC1， and SCD1 in mice and Huh7 cells decreased significantly （P<0.05， P<0.01）. ConclusionGastrodin can reduce hepatic lipid accumulation and blood lipid levels， improve HFHC-induced NAFLD， and its mechanism of action may be related to the regulation of the SREBP1c lipid synthesis-related signaling pathway.

Objective To explore the relationship between atherosclerotic index of plasma(AIP)and cognitive function in older adults.Methods A cross-sectional study method was used to include the National Health and Nutrition Examination Survey(NHANES)2011 to 2014 population aged>60 years as study subjects,and the population was divided into>-2.158 to≤-0.624 AIP group,>-0.624 to≤-0.123 AIP group,>-0.123 to≤0.309 AIP group,>0.309 AIP group 4 groups.Demographic data(including gender,age,race,education,marriage,height,and body mass),chronic disease-related data(including angina pectoris,emphysema,depression score,chronic bronchitis,coronary heart disease,history of stroke,hypertension,and diabetes mellitus),lifestyle-related data(including smoking and sleep duration),and cognitive function assessment[including the United Registry for consortium to establish a registry for Alzheimer's disease word list(CERAD W-L)score,animal fluency test(AFT)score and digit symbol substitution test(DSST)score],and to compare the differences in the above information between groups with different levels of AIP;and to analyze the factors affecting the cognitive function of the population by using multifactorial Logistic regression.Results A total of 1 335 participants were included in the analysis,and the results of the multivariate linear regression suggested that in model 3 after adjusting for all covariates,no linear relationship existed between AIP and CERAD W-L score for the>-0.624-≤-0.123 AIP group,the>-0.123-≤-0.309 AIP group,and the>-0.309 AIP group,compared with the>-2.158-≤-0.624 AIP group have a linear relationship(P=0.500 for the>-0.624-≤-0.123 AIP group,P=0.110 for the>-0.123-≤0.309 AIP group,and P=0.200 for the>0.309 AIP group).Weighted multifactor Logistic regression analyses after adjusting for covariates showed that AIP was a risk correlate for decline in representing immediate and delayed recall CERAD W-L score[odds ratio(OR)=0.970,95％confidence interval(95％CI)of 0.950-1.000,P=0.050].Restricted Cubic Splines of AIP versus CERAD W-L score restricted cubic spline(RCS)curves suggested a significant overall effect of CERAD W-L score on AIP(overall P=0.005),but not a significant nonlinear relationship(nonlinear P=0.278);and subgroup analyses showed that among 65-70 years old who were college-educated or better,married,and free of hypertension,AIP was the most prevalent among CERAD W-L scores.AIP is an associated risk factor for the development of CERAD W-L decline in people(OR<1,P<0.05).Conclusion AIP is a risk factor for cognitive decline associated with delayed and immediate memory,suggesting that AIP can be used as a predictor or assessment of cognitive function.

OBJECTIVE To establish the quality standard of Clinopodium gracile. METHODS Ten batches of C. gracile were collected to perform appearance and property identification， microscopic identification and thin layer chromatography （TLC） identification. Moisture， total ash， acid-insoluble ash and dilute ethanol extract were detected， and the content of rosmarinic acid was determined by HPLC. RESULTS The stem of C. gracile was slender， square columnar， covered by white fluff， the surface was grayish green or greenish brown； epidermal cells， non-glandular hairs， cortical cells and so on were seen in the cross section of the stem. Non-glandular hairs， ducts， wood fibers， mesophyll cells and so on could be seen in the powder. Results of TLC identification showed that there were spots of the same color in the chromatographic position corresponding to the chromatographic position of buddlejasaponin Ⅳb control. The contents of water， total ash， acid-insoluble ash， dilute ethanol extract and rosmarinic acid in 10 batches of samples were 8.69%-12.33%， 5.96%-13.33%， 0.14%-3.29%， 18.57%-32.61%， 0.35%-0.82%， respectively. The average values were 10.10%， 9.73%， 1.06%， 23.54% and 0.56%， respectively. CONCLUSIONS The established method can be used for quality control of C. gracile. It is preliminarily proposed that the ash content in the herb should not exceed 12.0%， the total ash content should not exceed 12.0%， the acid-insoluble ash content should not exceed 1.5%， the dilute ethanol extract should not be less than 18.0%， and the rosmarinic acid content should not be less than 0.45%.

Objective: To investigate the prevalence and influencing factors of depressive symptoms among grassroots healthcare workers in Zhejiang Province, so as to provide insights into improving their mental health. Methods: Grassroots healthcare workers of community health service centers and township health centers were sampled from one county (city, district) in each of 11 cities in Zhejiang Province using a convenience sampling method from December 2022 to January 2023. Participants' gender, age, educational level and average daily sleep duration in the past week were collected through questionnaires, and depression symptoms was investigated according to Self-rating Depression Scale. Factors affecting the depressive symptoms were identified using a multivariable logistic regression model. Results: A total of 1 946 questionnaires were distributed, and 1 945 valid questionnaires were recovered, with an effective response rate of 99.95%. There were 444 boys, accounting for 22.83%, and 1 501 girls, accounting for 77.17%. The median age was was 36 (interquartile range, 44) years. There were 786 healthcare workers detected with depressive symptoms, with a prevalence rate of 40.41%, and the prevalence rates of mild, moderate and severe depressive symptoms were 26.94%, 10.49% and 2.98%, respectively. Multivariable logistic regression analysis identified age (50 years and older, OR=0.572, 95%CI: 0.386-0.846), annual income (100 000 to 149 999 Yuan, OR=0.780, 95%CI: 0.635-0.958; 150 000 to 199 999 Yuan, OR=0.463, 95%CI: 0.282-0.760; 200 000 Yuan and above, OR=0.303, 95%CI: 0.098-0.937), vocation (nurse, OR=1.593, 95%CI: 1.252-2.027) and sleep duration (less than 7 hours, OR=2.164, 95%CI: 1.768-2.648) as factors affecting depressive symptoms among grassroots healthcare workers in Zhejiang Province. Conclusions The prevalence of depressive symptoms among grassroots healthcare workers in Zhejiang Province is 40.41%. Age, annual income, job and sleep duration may affect the development of depressive symptoms among grassroots healthcare workers.
