Objective:To assess the methodological and measurement quality of comprehensive assessment tools for evaluating senile dementia, in order to provide evidence-based guidance for clinical selection of the best assessment tool.Methods:Manually searched CNKI, Wanfang Database, VIP Database, SinoMed, PubMed, Embase, Web of Science, Cochrane Library, CINAHL, ProQuest, Ovid and Scopus databases to collect and evaluate comprehensive assessment tool measurements forsenile dementia. For research on academic attributes, the search time limit was from the establishment of the database to January 4th, 2024. Two researchers independently screened the literature and extracted information, used the COSMIN guidelines to evaluate the included assessment tools, and formed final recommendations.Results:A total of 14 articles were included, including 9 comprehensive assessment tools for the elderly with dementia. Among them, the Care Needs Assessment Scale for Alzheimer′s Disease Patients had moderate and above evidence proving that its content validity and internal consistency were "sufficient", so it was a category A strong recommendation. The remaining 8 evaluation tools were all category B recommendations.Conclusions:Among the existing comprehensive assessment tools for the elderly with dementia, the Care Needs Assessment Scale for Alzheimer′s Disease Patients has good reliability and validity. This scale has 4 dimensions and 16 items. However, there are uncertainties and unmentioned measurement properties of the scale in terms of cross-cultural validity/measurement equivalence, stability, measurement error, hypothesis testing, calibration validity, and responsiveness. More evidence is needed in the future to further comprehensively validate and improve it, providing a basis for selecting a more effective, comprehensive and high-quality comprehensive assessment tool for the elderly with dementia.

Objective To investigate the correlation between salivary cystatin D level and salivary gland injury in patients with primary Sj?gren syndrome(pSS).Methods A total of 51 pSS patients admitted in the Department of Rheumatology and Immunology of the First Affiliated Hospital of Xi'an Jiaotong University from September 1,2022 to June 30,2023,and 51 age-and gender-matched healthy individuals who took physical examination in the hospital during same period were enrolled in the study.The level of salivary cystatin D was detected,and the difference in the level between the 2 groups was compared using an independent-samples t test.Pearson correlation analysis was applied to analyze the correlation between salivary cystatin D and clinical parameters in the patients.Results The pSS patients had significantly lower cystatin D level than the healthy controls(206.55±108.11 vs 374.32±172.24 pg/mL,P＜0.01).The cystatin D level in the pSS patients was positively correlated with both static(r=0.433,P=0.002)and dynamic salivary flow rates(r=0.363,P=0.009).The patients with higher score of salivary gland ultrasonography(SGUS)had obviously lower cystatin D than those with lower SGUS score(parotid gland:160.75±85.56 vs 290.53±95.17 pg/mL,P＜0.01;submandibular gland:157.76±87.59 vs 276.25±97.06 pg/mL,P＜0.01).The cystatin D level was also negatively correlated with peripheral blood IL-6 level(r=-0.453,P=0.001)and CD4+T cell count(r=-0.396,P=0.005)in the pSS patients.Conclusion Salivary cystatin D level can be used as an indicator of salivary gland damage for pSS patients.

Objective: To investigate the influencing factors of depressive symptoms among rural elderly patients with chronic diseases in China, so as to provide insights into depression prevention and control among the rural elderly patients with chronic diseases. Methods: The basic demographics, health status, and lifestyle of rural residents at ages of 65 years and older who had at least one chronic disease were retrieved from The Chinese Longitudinal Healthy Longevity Survey (CLHLS) database in 2018, and participants' depressive symptoms were assessed with The Center for Epidemiological Studies Depression-10 (CES-D-10) scale. Factors affecting the depressive symptoms were identified with a multivariable logistic regression model. Results: Totally 5 146 rural elderly patients with chronic diseases were enrolled, including 2 373 men (46.11%) and 2 773 women (53.89%). The prevalence of depressive symptoms was 27.13%. Multivariable logistic regression analysis identified having two and more children (OR=0.614, 95%CI: 0.387-0.975), living alone (OR=1.450, 95%CI: 1.192-1.764), life satisfaction (general, OR=1.933, 95%CI: 1.651-2.264; low, OR=5.366, 95%CI: 3.488-8.254), self-assessed health status (general, OR=2.697, 95%CI: 2.284-3.185; poor, OR=5.338, 95%CI: 4.262-6.685), disability in instrumental activities of daily living (OR=1.592, 95%CI: 1.328-1.908), sleep duration (normal, OR=0.502, 95%CI: 0.429-0.586; too long, OR=0.494, 95%CI: 0.405-0.603), exercise (OR=0.721, 95%CI: 0.607-0.856), watching TV (OR=0.787, 95%CI: 0.664-0.933), and gardening activities (OR=0.781, 95%CI: 0.626-0.975) as factors affecting depressive symptoms among rural elderly patients with chronic diseases. Conclusions The prevalence of depressive symptoms was 27.13% among rural elderly patients with chronic diseases. Number of children, living style, life satisfaction, health status, sleep duration, exercise, watching TV, and gardening activities are associated with the development of depressive symptoms among rural elderly patients with chronic diseases.

BACKGROUND: This study aimed to develop a comprehensive instrument for evaluating and ranking clinical practice guidelines, named Scientific, Transparent and Applicable Rankings tool (STAR), and test its reliability, validity, and usability. METHODS: This study set up a multidisciplinary working group including guideline methodologists, statisticians, journal editors, clinicians, and other experts. Scoping review, Delphi methods, and hierarchical analysis were used to develop the STAR tool. We evaluated the instrument's intrinsic and interrater reliability, content and criterion validity, and usability. RESULTS: STAR contained 39 items grouped into 11 domains. The mean intrinsic reliability of the domains, indicated by Cronbach's α coefficient, was 0.588 (95% confidence interval [CI]: 0.414, 0.762). Interrater reliability as assessed with Cohen's kappa coefficient was 0.774 (95% CI: 0.740, 0.807) for methodological evaluators and 0.618 (95% CI: 0.587, 0.648) for clinical evaluators. The overall content validity index was 0.905. Pearson's r correlation for criterion validity was 0.885 (95% CI: 0.804, 0.932). The mean usability score of the items was 4.6 and the median time spent to evaluate each guideline was 20 min. CONCLUSION The instrument performed well in terms of reliability, validity, and efficiency, and can be used for comprehensively evaluating and ranking guidelines.

Despite the achievements obtained worldwide in the control of tuberculosis in recent years, many countries and regions including China still face challenges such as low diagnosis rate, high missed diagnosis rate, and delayed diagnosis of the disease. The discovery strategy of tuberculosis in China has changed from "active discovery by X-ray examination" to "passive discovery by self-referral due to symptoms", and currently the approach is integrated involving self-referral due to symptoms, active screening, and physical examination. Active screening could help to identify early asymptomatic and untreated cases. With the development of molecular biology and artificial intelligence-assisted diagnosis technology, there are more options for active screening among the large-scale populations. Although the implementation cost of a population-based active screening strategy is high, it has great value in social benefits, and active screening in special populations can obtain better benefits. Active screening of tuberculosis is an important component of the disease control. It is suggested that active screening strategies should be optimized according to the specific conditions of the regions to ultimately ensure the benefit of the tuberculosis control.

Objective:To explore the distribution characteristics of memory B cells and its relationship with bone erosion in patients with rheumatoid arthritis (RA), and to further understand the mechanism of B cells in the pathogenesis of RA.Methods:B cell subsets in peripheral blood of 200 RA patients and 50 healthy individuals were detected by flow cytometry. According to the surface markers CD19, CD27 and lgD, B cells were divided into CD19 +CD27 +lgD - switched memory B cells, CD19 +CD27 +lgD + non-switched memory B cells, CD19 +CD27 -lgD - double-negative memory B cells and CD19 +CD27 -lgD + naive B cells. B cells in RA patients with various disease activity score, course of disease and treatment were analyzed. Patients were divided into four groups according to the results of joint ultrasonography, including patients without bone erosion, patients with hand bone erosion, patients with knee bone erosion and patients with hand and knee bone erosion. The relationship between the distribution of B cell subsets, autoantibodies and RA bone erosion were analyzed. Differences between the groups were analyzed by independent-samples t test, Mann-Whitney U test and χ2 test. The analysis of variance, Kruskal-Wallis analysis were used for multi-group comparison, Spearman correlation analysis was also used for correlation analysis. Results:①RA patients showed significantly decreased non-switched memory B cells [(9.5±6.7)% vs (12.1±4.7)%, t=2.46, P=0.015] and increased double negative memory B cells [(3.8±2.5)% vs(2.7±1.3)%, t=-4.74, P<0.001] in comparison to healthy individuals. The percentage of non-switched memory B cells were decreased in RA patients with moderate disease activity [(8.4±4.7 )% vs (12.4±7.5)%, t=3.13, P=0.001] and high disease activity [(7.8±7.6)% vs (12.4±7.5)%, t=3.00, P=0.003] in comparison to those in RA patients who achieved remission. Meanwhile, the na?ve B cells [(70.3±15.0)% vs (63.9±14.6)%, t=-2.15, P=0.034] were increased in RA patients with moderate disease activity. No difference was found in RA patients with different disease courses. Total B cells [(4.8±2.9)% vs (7.2±4.1)%, t=-3.24, P=0.001], non-switched memory B cells (7.6±4.3)% vs (10.0±7.1)%, t=-2.63, P=0.010) in RA patients who received prednisone treatment were decreased, while double-negative memory B cells (4.9±3.0)% vs (3.6±2.3)%, t=-2.79, P=0.006] were increased compared with those in RA patients without prednisone treatment. Non-switched memory B cells was decreased in RA patients with hand and knee erosion compared with RA patients without erosion [6.8%(2.5%, 9.5%) vs 9.7%(5.5%, 17.5%), Z=-2.12, P=0.034]. Double negative memory B cells in subgroup with keen erosion [3.3%(2.7%, 5.0%) vs 2.6%(1.9%, 3.8%), Z=-2.09, P=0.036]as well as with hand and knee erosion [3.9%(2.3%, 5.6%) vs 2.6%(1.9%, 3.8%), Z=-2.41, P=0.016] were higher than those in patients without erosion. In addition, higher serum RF level was found in subgroup RA patients with hand and knee erosion compared with subgroup of RA patients without erosion [141.0 (38.0, 874.0) U/ml vs 53.5 (10.0, 106.0)U/ml, Z=-2.07, P=0.039]. Meanwhile, the positive rate of ACPA in RA patients with bone erosion of hand was significantly higher than that of RA patients without bone erosion [81%(52/64) vs 64%(38/59), χ2=4.44, P=0.043). Conclusions:The results suggest that the increase of double negative memory B cells, the decrease of non-switched memory B cells and higher level of autoantibodies may closely relate to bone erosion of RA, which may be one of the pathogenesis of disability in RA.

Objective:To study the cytotoxicity and malignant transformation ability of chrysotile on MeT-5A cells.Methods:In June 2016, lactate dehydrogenase (LDH) method was used to detect the cytotoxicity of chrysotile to MeT-5A cells. MeT-5A cells were treated with 5 μg/cm 2 chrysotile intermittently for 24 h a time, once a week and a total of 28 times. After the cells showed anchorage independent growth, the cell features of malignant transformation were identified by colony forming frequency in soft agar, and the soft agar colony formation rates were calculated. The activities of key speed limiting enzymes of glycolysis metabolism including hexokinase (HK) , phosphofructokinase (PFK) and pyruvate kinase (PK) were determined by UV colorimetry. Results:Chrysotile was cytotoxic to MeT-5A cells in a concentration-dependent decline. Compared with the control group, the relative survival rates of MeT-5A cells were significantly decreased after exposed to chrysotile at 10, 20, 40 and 80 μg/cm 2 ( P<0.05) . After 28 times of exposure, the growth rate of the cells in chrysotile transformed MeT-5A cells was accelerated, the arrangement was disordered, the contact inhibition was lost, and the double layer growth appeared, which could grow on soft agar. The colony forming rate of the chrysotile transformed MeT-5A cells was 18.33‰±2.49‰. Compared with the control group (0) , the difference was statistically significant ( P<0.01) . The activities of glycolysis related kinase including PK [ (19.51±1.52) U/L], PFK[ (0.12±0.02) U/10 4 cell] and HK[ (0.26±0.01) U/10 4 cell] were increased in the chrysotile transformed MeT-5A cells compared with control group [ (25.00±1.04) U/L、(0.15±0.01) U/10 4 cell and (0.33±0.01) U/10 4 cell] ( P<0.01) . Conclusion:Chrysotile can induce malignant transformation of MeT-5A cells and increase the activities of glycolysis related kinases including PK, PFK and HK.
