Abstract
The incidence of intestinal diseases increases with age, yet the mechanisms governing gut aging and its link to diseases, such as colorectal cancer (CRC), remain elusive. In this study, while considering age, sex and proximal-distal variations, we used a multi-omics approach in non-human primates (Macaca fascicularis) to shed light on the heterogeneity of intestinal aging and identify potential regulators of gut aging. We explored the roles of several regulators, including those from tryptophan metabolism, in intestinal function and lifespan in Caenorhabditis elegans. Suggesting conservation of region specificity, tryptophan metabolism via the kynurenine and serotonin (5-HT) pathways varied between the proximal and distal colon, and, using a mouse colitis model, we observed that distal colitis was more sensitive to 5-HT treatment. Additionally, using proteomics analysis of human CRC samples, we identified links between gut aging and CRC, with high HPX levels predicting poor prognosis in older patients with CRC. Together, this work provides potential targets for preventing gut aging and associated diseases.

Abstract
Protein posttranslational modifications (PTMs) refer to the breaking or generation of covalent bonds on the backbones or amino acid side chains of proteins and expand the diversity of proteins, which provides the basis for the emergence of organismal complexity. To date, more than 650 types of protein modifications, such as the most well-known phosphorylation, ubiquitination, glycosylation, methylation, SUMOylation, short-chain and long-chain acylation modifications, redox modifications, and irreversible modifications, have been described, and the inventory is still increasing. By changing the protein conformation, localization, activity, stability, charges, and interactions with other biomolecules, PTMs ultimately alter the phenotypes and biological processes of cells. The homeostasis of protein modifications is important to human health. Abnormal PTMs may cause changes in protein properties and loss of protein functions, which are closely related to the occurrence and development of various diseases. In this review, we systematically introduce the characteristics, regulatory mechanisms, and functions of various PTMs in health and diseases. In addition, the therapeutic prospects in various diseases by targeting PTMs and associated regulatory enzymes are also summarized. This work will deepen the understanding of protein modifications in health and diseases and promote the discovery of diagnostic and prognostic markers and drug targets for diseases.

Abstract
Skeletal muscle makes up 30-40% of the total body mass. It is of great significance in maintaining digestion, inhaling and exhaling, sustaining body posture, exercising, protecting joints and many other aspects. Moreover, muscle is also an important metabolic organ that helps to maintain the balance of sugar and fat. Defective skeletal muscle function not only limits the daily activities of the elderly but also increases the risk of disability, hospitalization and death, placing a huge burden on society and the healthcare system. Sarcopenia is a progressive decline in muscle mass, muscle strength and muscle function with age caused by environmental and genetic factors, such as the abnormal regulation of protein post-translational modifications (PTMs). To date, many studies have shown that numerous PTMs, such as phosphorylation, acetylation, ubiquitination, SUMOylation, glycosylation, glycation, methylation, S-nitrosylation, carbonylation and S-glutathionylation, are involved in the regulation of muscle health and diseases. This article systematically summarizes the post-translational regulation of muscle growth and muscle atrophy and helps to understand the pathophysiology of muscle aging and develop effective strategies for diagnosing, preventing and treating sarcopenia.

Abstract
GSK3α and GSK3β are two GSK3 isoforms with 84% overall identity and 98% identity in their catalytic domains. GSK3β plays important roles in the pathogenesis of cancer, while GSK3α has long been considered a functionally redundant protein of GSK3β. Few studies have specifically investigated the functions of GSK3α. In this study, unexpectedly, we found that the expression of GSK3α, but not GSK3β, was significantly correlated with the overall survival of colon cancer patients in 4 independent cohorts. To decipher the roles of GSK3α in colon cancer, we profiled the phosphorylation substrates of GSK3α and uncovered 156 phosphosites from 130 proteins specifically regulated by GSK3α. A number of these GSK3α-mediated phosphosites have never been reported before or have been incorrectly identified as substrates of GSK3β. Among them, the levels of HSF1S303p, CANXS583p, MCM2S41p, POGZS425p, SRRM2T983p, and PRPF4BS431p were significantly correlated with the overall survival of colon cancer patients. Further pull-down assays identified 23 proteins, such as THRAP3, BCLAF1, and STAU1, showing strong binding affinity to GSK3α. The interaction between THRAP3 and GSK3α was verified by biochemical experiments. Notably, among the 18 phosphosites of THRAP3, phosphorylation at S248, S253, and S682 is specifically mediated by GSK3α. Mutation of S248 to D (S248D), which mimics the effect of phosphorylation, obviously increased cancer cell migration and the binding affinity to proteins related to DNA damage repair. Collectively, this work not only discloses the specific function of GSK3α as a kinase but also suggests GSK3α as a promising therapeutic target for colon cancer.

Abstract
Rheumatoid arthritis (RA) is a typical autoimmune disease characterized by synovial inflammation, synovial tissue hyperplasia, and destruction of bone and cartilage. Protein glycosylation plays key roles in the pathogenesis of RA but in-depth glycoproteomics analysis of synovial tissues is still lacking. Here, by using a strategy to quantify intact N-glycopeptides, we identified 1260 intact N-glycopeptides from 481 N-glycosites on 334 glycoproteins in RA synovium. Bioinformatics analysis revealed that the hyper-glycosylated proteins in RA were closely linked to immune responses. By using DNASTAR software, we identified 20 N-glycopeptides whose prototype peptides were highly immunogenic. We next calculated the enrichment scores of nine types of immune cells using specific gene sets from public single-cell transcriptomics data of RA and revealed that the N-glycosylation levels at some sites, such as IGSF10_N2147, MOXD2P_N404, and PTCH2_N812, were significantly correlated with the enrichment scores of certain immune cell types. Furthermore, we showed that aberrant N-glycosylation in the RA synovium was related to increased expression of glycosylation enzymes. Collectively, this work presents, for the first time, the N-glycoproteome of RA synovium and describes immune-associated glycosylation, providing novel insights into RA pathogenesis.

Abstract
Mental disorders are associated with dysregulated metabolism, but comprehensive investigations of their metabolic similarities and differences and their clinical relevance are few. Here, based on the plasma metabolome and lipidome of subcohort1, comprising 100 healthy participants, 55 cases with anxiety, 52 persons with depression, and 41 individuals with comorbidity, which are from WCHAT, a perspective cohort study of community‐dwelling older adults aged over 50, multiple metabolites as potential risk factors of mental disorders were identified. Furthermore, participants with mental illnesses were classified into three subtypes (S1, S2, and S3) by unsupervised classification with lipidomic data. Among them, S1 showed higher triacylglycerol and lower sphingomyelin, while S2 displayed opposite features. The metabolic profile of S3 was like that of the normal group. Compared with S3, individuals in S1 and S2 had worse quality of life, and suffered more from sleep and cognitive disorders. Notably, an assessment of 6,467 individuals from the WCHAT showed an age‐related increase in the incidence of depression. Seventeen depression‐related metabolites were significantly correlated with age, which were validated in an independent subcohort2. Collectively, this work highlights the clinical relevance of metabolic perturbation in mental disorders, and age‐related metabolic disturbances may be a bridge‐linking aging and depressive.

Abstract
Background The optimal criteria for sarcopenia in the older Chinese population have not been defined. Consequently, this study aims to determine the optimal cutoffs of grip strength, appendicular skeletal muscle index (ASMI) using bioelectrical impedance analysis (BIA), and gait speed, comprising the best definition of sarcopenia for older Chinese populations. Methods A total of 2,821 (1,398 men and 1,423 women) community-dwelling older people (≥60 years) and 409 (205 men and 204 women) young healthy adults (25–34 years) were recruited from three big cities in China. Besides gait speed and grip strength, we examined ASMI by BIA and dual-energy X-ray absorptiometry (DXA), comprising the three components of sarcopenia. DXA classification for low ASMI, 20th percentile among older adults in the study sample, was found to be best compared with the other existing classification, 1 SD and 2 SD below the mean for the young population, and was used as the gold standard to determine the optimal cutoffs of BIA using receiver operating characteristic curves (ROC). The cutoffs of handgrip strength and gait speed were determined following the same rule. Results Using gender-specific 20th percentiles of DXA (6.53 kg/m2 for men and 5.40 kg/m2 for women), the cutoffs 7.05 kg/m2 for men and 5.85 kg/m2 for women were determined as optimal cutoffs of BIA by achieving the largest sensitivity (0.81, 95% CI: 0.63–0.93 for men and 0.90, 95% CI: 0.73–0.98 for women) and specificity greater than 0.80 (0.80, 95% CI: 0.72–0.87 for men and 0.81, 95% CI: 0.72–0.87 for women) in the ROC analysis. The 28.5 kg and 1.05 m/s for men and 18.6 kg and 1.01 m/s for women were determined as the cutoffs for handgrip strength and gait speed, respectively. Based on the derived cutoffs, 14.2% of men and 15.7% of women in the older Chinese study population were classified as sarcopenia. Conclusion Notably, 7.05 kg/m2, 28.5 kg, and 1.05 m/s for men and 5.85 kg/m2, 18.6 kg, and 1.01 m/s for women were selected as the optimal cutoffs for low ASMI by BIA, handgrip strength, and gait speed, respectively. These optimal cutoffs will enhance practicability for screening sarcopenia in primary care and clinical settings.

Abstract
Purpose Malnutrition and population ageing are doubly global healthcare challenges. It is widely recognized that disability is a major contributor to malnutrition among older people, but the importance of reducing malnutrition risk (MR) for disability prevention is given little attention. We investigated the association between MR and risk of incident disability and functional decline among community-dwelling older persons. Materials and Methods Prospective cohort study of community-dwelling older adults aged 55 and above (Singapore Longitudinal Ageing Study) with 3–5 years follow-up. MR was measured at baseline using an appropriate and validated index (ENIGMA); physical and functional measures at baseline and follow-up included instrumental and basic activity of daily living (ADL), knee extension (KES), gait velocity (GV), timed up-and-go (TUG). Results Compared to low MR, mild-moderate MR (OR = 1.43, 95% CI = 1.02–2.01) and severe MR (OR=1.74, 95% CI=1.10–2.74) were associated with higher risks of incident disability. Severe MR was associated with functional decline (OR = 1.69, 95% CI = 1.11–2.57). Estimates were adjusted for demographic, social, lifestyle behaviour and health variables. In particular, eating difficulty was associated with incident disability and functional decline, and low lymphocyte with functional decline. Severe MR and low albumin were associated with 37% worse GV and 126% worse TUG declines; consuming few vegetables or fruits with 34% worse KES decline; polypharmacy with 56% worse TUG decline. Conclusion Malnutrition risk increased the risk of incident disability and functional decline in non-disabled persons, it worsened physical performance declines. Further studies should investigate the effectiveness of nutritional interventions in reducing the risk of disability among older people.

Abstract
OBJECTIVES Data regarding the occurrence of risk factors that promote the loss of muscle mass, strength and function in sarcopenia patients in elderly Chinese patients are sparse. Here, we investigated the alterations in muscle mass, function and strength in those with sarcopenia over a 4-year period. We further evaluated the risk factors leading to a loss of grip strength, gait speed and skeletal muscle mass index in sarcopenia patients. DESIGN A face-to-face cross-sectional survey. SETTING AND PARTICIPANTS The study population consisted of 560 Chinese aged over 59 years. MEASUREMENTS Study recordings took places over a four-year period from 2014. Muscle mass was assessed through bioelectrical impedance analysis (BIA) performed on an Inbody720, Biospace. Hand-grip strength and 6 m walking speed were used as measurements of muscle strength and function. Sarcopenia was diagnosed using the Asian Working Group for Sarcopenia criteria (AWGS). RESULTS In total, 474 of the elderly residents completed the follow-up. The rates of decreased ASMI, grip strength, and gait speed in the sarcopenia patients increased over the 4-year period. Following multivariate analysis, age was identified as the main risk factor for all the observed decrease, gender was specifically related to the loss of ASMI, stroke was a risk factor for gait speed and sarcopenia. A high BMI was a risk factor for a low gait speed but was protective for a loss of skeletal muscle mass and sarcopenia. CONCLUSIONS Age leads to a decline in muscle strength and function. In elderly Chinese patients with sarcopenia, the rates of reduced grip strength, gait-speed and sarcopenia increased. A high BMI was protective against the decline in muscle mass and sarcopenia, but represented a risk factor for low gait speed. Stoke was identified to cause a loss of gait speed in sarcopenia patients.

Abstract
BACKGROUND AND OBJECTIVES The increasing prevalence of malnutrition in old people is related to the risk of illness and death. A number of screening tools to detect malnutrition have been used in the elderly to assess nutritional status and predict prognosis. The aim of the present study was to investigate the ability of the Geriatric Nutritional Risk Index (GNRI) to assess nutritional status and predict mortality in very old home-care people by using a cross-sectional study of Chinese older people aged 90-105 years. METHODS AND STUDY DESIGN The present study was based on a 4-year follow-up of mortality data from a previous cross-sectional study. The study was conducted with a very elderly population with a mean age of 93.5±3.2 years (n=716; 230 men and 486 women). In 2005, trained researchers performed face-to-face interviews and physical and geriatric assessments to obtain information on sociodemographic factors, self-reported medical diseases, geriatric-specific conditions, anthropometric factors, biochemical data, and the GNRI score. In 2009, vital status were requested from the local government. RESULTS After 4 years of follow-up, 371 participants died (125 men and 246 women, 51.8%). The median follow-up time was significantly worse in the nutritional risk group (GNRI <=98) (30.26±15.80 vs 42.27±11.82 months, p<0.001). Activities of daily living (ADL) impairment (hazard ratio [HR]=1.414, 95% CI=1.121-1.783), and GNRI score (HR=0.92, 95% CI=0.908-0.932) were associated with all-cause mortality according to a Cox regression analysis. CONCLUSIONS The GNRI, a nutrition-related risk index, can predict mortality in very old Chinese home-care people.

Abstract
Background Frailty is common and associated with poorer outcomes in the elderly, but its prognostic value in acute coronary syndromes (ACS) requires clarification. We thus undertook a systematic review and meta-analysis to evaluate the relationship between frailty and poor prognosis in patients with ACS. Methods We systematically searched PubMed, Embase to find literatures which studied the prognostic value of frailty in elderly patients with ACS. Our main endpoints were the all-cause mortality, cardiovascular disease (CVD), major bleeding and readmissions. We pooled studies using random-effect generic inverse variance method, and conducted three pre-specified subgroup analyses. Results Of 1216 identified studies, 15 studies were included in our analysis. Compared with the normal group, frailty (HR = 2.65; 95%CI: 1.81–3.89, I2 = 60.2%) and pre-frailty (HR = 1.41; 95%CI: 1.19–1.66, I2 = 0%) were characterized by a higher risk of mortality after adjustment. Frailty also was associated with increased risk of any-type CVD, major bleeding and hospital readmissions in elderly patients with ACS. The pooled effect sizes in frail patients were 1.54 (95%CI: 1.32–1.79), 1.51 (95%CI: 1.14–1.99) and 1.51 (95%CI: 1.09–2.10). Conclusions Frailty provides quantifiable and significant prognostic value for mortality and adverse events in elderly ACS patients, helping doctors to appraise the comprehensive prognosis risk and to applicate appropriate management strategies.

Abstract
OBJECTIVE To determine the prevalence of sarcopenia in community-dwelling elderly populations in Chengdu and its associated risk factors. METHODS A total of 947 community dwelling residents aged ≥60 yr. in Chengdu participated in this study. Their appendicular skeletal muscle mass was measured through bioelectrical impedance analyses. Sarcopenia was defined using the diagnostic algorithm recommended by the Asia Working Group (AWGS) for Sarcopenia. Data in relation to the demographic characteristics, chronic diseases and life style of the participants were obtained through a questionnaire survey, which included the 15-item geriatric depression scale (GDS-15) and the mini nutritional assessment (MNA). RESULTS Overall, 10.5% of the elderly participants were identified with sarcopenia: 8.4% in men and 12.5% in women. The prevalence of sarcopenia increased with age: 2.3% in the 60-64 yr., 5.6% in the 65-74 yr., 19.7% in the ≥75 yr.. Age [odds ratio (OR)=1.109, 95% confldence interval (CI):1.054-1.168], smoking (OR=3.482, 95%CI:1.356-8.938) and Malnorishment (OR=5.598, 95%CI:2.677-11.709) are significant predictors of sarcopenia after adjustment for potential confounders. CONCLUSION Approximately 10% community-dwelling elderly in Chengdu have sarcopenis. Age, smoking, malnutrition are risk factors of sarcopenia.

Abstract
This study aimed to evaluate the association between skeletal muscle mass and long-term all-cause mortality among nonagenarians and centenarians in China. We used data from the Project of Longevity and Aging in Dujiangyan (PLAD). A total of 738 community-dwelling people aged ≥ 90 years (mean age of 93.5 ± 3.2 years) were analyzed in this study. The appendicular skeletal muscle mass (ASM) was estimated using a previously validated anthropometric equation. The information on the survival status was requested from the local government registries during the 4 year follow-up period following the baseline investigation. The mean muscle mass index (SMI) was 6.11 ± 0.53 kg/m2 in men and 4.00 ± 0.63 kg/m2 in women, respectively. Low muscle mass was associated with a higher risk of death (hazard ratio [HR] 1.54; (95% confidence interval [CI]:1.10–2.16) in women; however, no significant association was found in men. Disability in activities of daily living (ADL) (HR = 1.73; 95% CI: 1.13–2.63) in men and women and cognitive impairment (HR = 1.49; 95% CI: 1.05–2.13) in men were also associated with increased all-cause mortality. In conclusion, low muscle mass were predictors of long-term mortality in nonagenarian and centenarian women.

Abstract
INTRODUCTION This study aimed to estimate the prevalence of sarcopenic obesity (SO) and the association between cognitive impairment and SO in a cohort of elderly Chinese community-dwelling individuals. METHODS A total of 948 elderly Chinese community-dwelling individuals aged 60-92 years were recruited. The participants were categorized into the following four groups according to their sarcopenia and obesity status: sarcopenic obese, sarcopenic, obese and non-sarcopenic, and non-obese group. Sarcopenia was defined as appendicular skeletal muscle index of <7.0 kg/m2 in men and <5.7 kg/m2 in women; obesity was defined as values greater than the upper two quintiles for body fat percentage stratified by gender of the study population; cognitive impairment was measured using the Mini-Mental State Examination and defined as a score of <24. RESULTS A total of 945 participants were included in the statistical analyses with a mean age of 68.76 ± 6.50 years. The prevalence of SO was 6.0% (7.3% in men and 4.8% in women). The sarcopenic obese (odds ratio [OR]: 2.550, 95% confidence interval [CI], 1.196-5.435) and obese (ORs: 2.141, 95% CI, 1.230-3.728) groups had significantly increased risk for cognitive impairment in fully adjusted model, respectively. CONCLUSION The SO prevalence in elderly Chinese community-dwelling individuals was relatively low (6.0%). The present study suggested SO was independently associated with cognitive impairment.

Purpose The aim of this study was to assess the prevalence of sarcopenia and depressive symptoms and estimate the association between them in elderly Chinese community-dwelling individuals. Patients and methods A total of 948 elderly Chinese community-dwelling individuals were recruited through leaflets and posters from three communities in Chengdu, and 865 participants were analyzed in this cross-sectional study. Muscle mass was measured using the bioimpedance analysis, handgrip strength was measured with a handheld dynamometer, and physical performance was assessed via usual gait speed on a 6 m course. Sarcopenia was defined according to the recommended diagnostic algorithm of the Asia Working Group for Sarcopenia (AWGS). Depressive symptoms were assessed using the Chinese version of 15-item Geriatric Depression Scale (GDS-15) with a score of ≥5 indicative of the presence of depressive symptoms. Results A total of 865 participants were included in the analysis. The participants had a mean age of 68.68±6.46 years. Sixty-one (7.1%) participants and 71 (8.2%) participants were identified as having sarcopenia and depressive symptoms, respectively. After adjusting for age, sex, and other potential confounders, sarcopenia was found to be significantly associated with depressive symptoms (odds ratio [OR]: 2.23, 95% CI 1.06–4.92). Conclusion The prevalence rates of sarcopenia and depressive symptoms were 7.1 and 8.2%, respectively, in elderly Chinese community-dwelling individuals, and sarcopenia was significantly associated with depressive symptoms.

Abstract
Background Sarcopenia is defined as the age-related decline in skeletal muscle mass and function. The risk factors and causes of sarcopenia must be identified to develop prevention and treatment strategies for this syndrome. Our aim was to examine the association between sarcopenia with lifestyle and family function among community-dwelling Chinese people aged 60 years and older. Methods We conducted this study to evaluate sarcopenia among 834 community-dwelling Chinese individuals aged ≥60 years using the Asian Working Group for Sarcopenia (AWGS) criteria. The sociodemographic characteristics, food consumption patterns, habits of smoking, and alcohol consumption of the participants were collected using a general questionnaire, whereas physical activity was assessed using the International Physical Activity Questionnaire (IPAQ; long-form version). Family function was assessed using the Family APGAR scale. In addition, the association of sarcopenia with lifestyle and family function was examined using univariate and multivariate analyses. Results The total prevalence rate of sarcopenia was 10.6%. Female participants with sarcopenia had a lower frequency per week of nut consumption than those without sarcopenia (p < 0.05), whereas, for male participants, the differences in food consumption patterns of those with sarcopenia versus those without sarcopenia were not significant. Among the participants, the mean Family APGAR score was 8 (standard deviation [SD] = 0.92). For both sexes, participants with sarcopenia had lower family function scores than those without sarcopenia. In the multivariate model, after adjustment for all covariates, frequency per week of nut consumption (adjusted OR 0.724, 95% CI 0.532–0.985, P < 0.05) and Family APGAR score (adjusted OR 0.683, 95% CI 0.496–0.940, P = 0.019) were statistically significantly associated with sarcopenia. The relationship between other lifestyle habits and sarcopenia was not significant. Conclusion There was significant association between sarcopenia with intake of nuts and family function. Further studies should evaluate if adequate intake of nuts and a well-functioning family may be effective in lowering the risk of sarcopenia.

Abstract
The aim of this systematic review and meta-analysis was to examine the association between sarcopenia and all-cause mortality among community-dwelling older people. A systematic review was performed using three electronic databases (EMBASE, MEDLINE and the Cochrane Library) to identify prospective cohort studies from January 2009 to February 2017 examining sarcopenia as a predictor of all-cause mortality among community-dwelling older people. We conducted a pooled analysis of mortality associated with sarcopenia, and subgroup analyses based on measurements of muscle mass and length of follow-up by employing a random-effects model. Sensitivity analyses were performed evaluate the cause of high heterogeneity. In addition, methodological quality, heterogeneity and publication bias were evaluated. Of 1703 studies identified, 6 studies incorporating 7367 individuals were included in the meta-analysis for all-cause mortality. The pooled hazard ratios (HRs) of all-cause mortality from the combination of included studies suggested participants with sarcopenia had a significantly higher rate of mortality (pooled HR 1.60, 95%CI 1.24-2.06, I2=27.8%, p=0.216) than participants without sarcopenia. The subgroup analysis for length of follow-up suggested studies with a follow-up period of less than 5 years found a higher risk of all-cause mortality (pooled HR 2.09, 95%CI 1.21-3.60) than studies with a follow-up period of 5 years or more (pooled HR 1.52, 95%CI 1.14-2.01). A subgroup of anthropometric measures was found to identify higher mortality risks (pooled HR 2.26, 95%CI 1.30-3.92) than a subgroup of dual-energy x-ray (DXA) absorptiometry (pooled HR 1.82, 95%CI 1.04-3.18) factors or a subgroup of bioelectrical impedance analysis (BIA) factors (pooled HR 1.31, 95%CI 1.15-1.49). Sarcopenia is a predictor of all-cause mortality among community-dwelling older people. Therefore, it is important to diagnose sarcopenia and to intervene, in order to reduce mortality rates in the elderly.

Abstract
BACKGROUND The aim of the present study was to validate the usefulness of the new octapolar multifrequency bioelectrical impedance analysis (BIA) for assessment of appendicular skeletal muscle mass (ASM) by comparing it with that of dual-energy X-ray absorptiometry (DXA) and to investigate the prevalence of sarcopenia in Chinese community-dwelling elderly according to Asian Working Group for Sarcopenia (AWGS) definition. METHODS A cross-sectional study was conducted in communities of Chengdu, China. A total of 944 community-dwelling elderly adults aged ≥60 years were included. ASM was measured by using DXA as a criterion method to validate a standing eight-electrode multifrequency BIA (InBody 720), followed by a further estimation of the prevalence of sarcopenia according the AWGS definition. RESULTS In the Bland-Altman analysis, no significant difference was found between DXA and BIA based on the ASM measurements. The prevalence of AWGS-defined sarcopenia was 12.5% in the elderly women and 8.2% in the elderly men. CONCLUSIONS BIA is suitable for body composition monitoring (ASM) in elderly Chinese as a fast, noninvasive, and convenient method; therefore, it may be a better choice in large epidemiological studies in the Chinese population. The prevalence of AWGS-defined sarcopenia was approximately 10.4% and increased with age in the Chinese community-dwelling elderly in this study.

Abstract
Little is known about the relationship between falls and various physical activities in the oldest old people. This study was conducted to observe the association of fall with various exercise habits and farm work in very old people. In this cross-sectional study of a Chinese cohort of men and women aged 90-108 years, we observed the association of fall with habitual (current and former) farm work and exercise in very old people. The population included 805 unrelated Chinese nonagenarians and centenarians (68.94% of the subjects were women, with a mean age of 93.70 years). In the women, the subjects with a continuing exercise habit had a significantly lower prevalence of fall than those without an exercise habit; the subjects who had never exercised had a significantly higher prevalence of fall than those who exercised. In men, there was no significant difference in the prevalence of these habits between the subjects with and without fall. After adjusting for age, gender, body mass index, educational levels, life styles, vision levels and temperament, we found that current habitual farm work (OR=1.755 95% CI (1.107, 2.780)) and exercise OR=0.666 95% CI (0.445, 0.997) had a significant odds ratio for fall; among the females, continuing exercise (vs. having never exercised) had a significant odds ratio for fall (OR=0.620 95% CI (0.395, 0.973)). Habitual farm work might be positively associated with fall; however, habitual exercise might be negatively associated with fall in Chinese long-lived old people.

Abstract
BACKGROUND Rarer dementias include Huntington's disease (HD), cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), frontotemporal dementia (FTD), dementia in multiple sclerosis (MS) and progressive supranuclear palsy (PSP). Cholinesterase inhibitors, including donepezil, galantamine and rivastigmine, are considered to be the first-line medicines for Alzheimer's disease and some other dementias, such as dementia in Parkinson's disease. Cholinesterase inhibitors are hypothesised to work by inhibiting the enzyme acetylcholinesterase (AChE) which breaks down the neurotransmitter acetylcholine. Cholinesterase inhibitors may also lead to clinical improvement for rarer dementias associated with neurological conditions. OBJECTIVES To assess the efficacy and safety of cholinesterase inhibitors for cognitive impairment or dementia associated with neurological conditions. SEARCH METHODS We searched the Cochrane Dementia and Cognitive Improvement Group's Specialised Register, CENTRAL, MEDLINE, EMBASE, PsycINFO, CINAHL, LILACS, several trial registries and grey literature sources in August 2013. SELECTION CRITERIA We included randomised, double-blind, controlled trials assessing the efficacy of treatment of rarer dementias associated with neurological conditions with currently marketed cholinesterase inhibitors. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility and quality of trials, and extracted data. We used the standard methodological procedures of the Cochrane Collaboration. MAIN RESULTS We included eight RCTs involving 567 participants. Six studies used a simple parallel-group design; the other two consisted of an open-label treatment period followed by a randomised phase. All trials were well concealed for allocation and double-blind, however the sample sizes of most trials were small. All trials used placebo as control. We performed meta-analyses for some outcomes in patients with MS. For all other conditions, results are presented narratively.Two trials included patients with HD; one found that cholinesterase inhibitor use in the short-term had no statistically significant impact on the cognitive portion of the Alzheimer Disease Assessment Scale (ADAS-Cog; 1 study, WMD 1.00, 95% CI -1.66 to 3.66, P = 0.46; low quality evidence), Unified Huntington's Disease Rating Scale (UHDRS) Verbal Fluency Test (1 study, WMD -1.20, 95% CI -7.97 to 5.57, P = 0.73; low quality evidence), UHDRS Symbol Digit Modalities Test (SDMT; 1 study, WMD 2.70, 95% CI -0.95 to 6.35, P = 0.15; low quality evidence) and other psychometric tests. The other study found that cholinesterase inhibitor use in the medium-term improved the results of the verbal fluency test (1 study, WMD 6.43, 95% CI 0.66 to 12.20, P = 0.03; moderate quality evidence) and California Verbal Learning Test - Second Edition (CVLT-II) Recognition Task (1 study, WMD 2.42, 95% CI 0.17 to 4.67, P = 0.04; moderate quality evidence). There was no statistically significant difference between groups on the SDMT (1 study, WMD -0.31, 95% CI -7.77 to 7.15, P = 0.94; moderate quality evidence), CVLT-II trials 1-5 (1 study, WMD -2.09, 95% CI -11.65 to 7.47, P = 0.67; moderate quality evidence), short-delay recall (1 study, WMD 0.35, 95% CI -2.87 to 3.57, P = 0.83; moderate quality evidence), or long-delay recall (1 study, WMD -0.14, 95% CI -3.08 to 2.80, P = 0.93; moderate quality evidence), and other psychometric tests.Four trials included patients with MS; one found no differences between the cholinesterase inhibitors (short-term) and placebo groups on the Wechsler Memory Scales general memory score (1 study, WMD 0.90, 95% CI -0.52 to 2.32, P = 0.22; low quality evidence). The three other trials found that, in the medium-term - cholinesterase inhibitors improved the clinician's impression of cognitive change (2 studies, OR 1.96, 95% CI 1.06 to 3.62, P = 0.03; high quality evidence). However, the treatment effect on other aspects of cognitive change were unclear, measured by the Selective Reminding Test (3 studies, WMD 1.47, 95% CI -0.39 to 3.32, P = 0.12; high quality evidence), patient's self-reported impression of memory change (2 studies, OR 1.67, 95% CI 0.93 to 3.00, P = 0.08; high quality evidence) and cognitive change (1 study, OR 0.95, 95% CI 0.45 to 1.98, P = 0.89; high quality evidence), clinician's impression of memory change (1 study, OR 1.50, 95% CI 0.59 to 3.84, P = 0.39; moderate quality evidence), other psychometric tests, and activities of daily living - patient reported impact of multiple sclerosis activities (1 study, WMD -1.18, 95% CI -3.02 to 0.66, P = 0.21; low quality evidence).One study on patients with CADASIL found a beneficial effect of cholinesterase inhibitors on the Executive interview, and Trail Making Test parts A and B. The impact of cholinesterase inhibitors on the Vascular ADAS-Cog score (1 study, WMD 0.04, 95% CI -1.57 to 1.65, P = 0.96; high quality evidence), the Clinical Dementia Rating Scale Sum of Boxes (1 study, WMD -0.09, 95% CI -0.48 to 0.03, P = 0.65; high quality evidence) Disability Assessment for Dementia scale (1 study, WMD 0.58, 95% CI -2.72 to 3.88, P = 0.73; moderate quality evidence), and other measures was unclearOne study included patients with FTD. This trial consisted of an open-label treatment period followed by a randomised, double-blind, placebo-controlled phase. No data of primary outcomes were reported in this study.In the included studies, the most common side effect was gastrointestinal symptoms. For all conditions, compared to the treatment group, the placebo group experienced significantly less nausea (6 studies, 44/257 vs. 22/246, OR 2.10, 95% CI 1.22 to 3.62, P = 0.007; high quality evidence), diarrhoea (6 studies, 40/257 vs. 13/246, OR 3.26, 95% CI 1.72 to 6.19, P = 0.0003; moderate quality evidence) and vomiting (3 studies, 17/192 vs. 3/182, OR 5.76, 95% CI 1.67 to 19.87, P = 0.006; moderate quality evidence). AUTHORS' CONCLUSIONS The sample sizes of most included trials were small, and some of the results were extracted from only one study. There were no poolable data for HD, CADASIL and FTD patients and there were no results for patients with PSP. Current evidence shows that the efficacy on cognitive function and activities of daily living of cholinesterase inhibitors in people with HD, CADASIL, MS, PSP or FTD is unclear, although cholinesterase inhibitors are associated with more gastrointestinal side effects compared with placebo.

Abstract
OBJECTIVE To investigate the occurrence and risk factors of mild cognitive impairment (MCI) and the conversion rates to dementia in Chinese people over 80 years of age. METHODS Two hundred and two participants (>80 years old) without dementia were assessed clinically using neuropsychological tests; they were re-assessed at 1, 2, and 3 years. RESULTS The results revealed that 30.2% of the study population was classified as having MCI at baseline. Multivariate linear regression analysis showed that coronary heart disease, hypertension, and stroke were risk factors of MCI. During the 3 years follow-up, the occurrence of MCI increased, and 21.8% of the participants with MCI progressed to dementia. CONCLUSIONS These results suggest that in the older elderly, prevention and early treatment of cardiovascular and cerebrovascular diseases may be effective in lowering the risk of MCI. MCI is a high risk factor for dementia.

Abstract
INTRODUCTION The Saint Louis University Mental Status (SLUMS) examination is a popular screening scale for cognitive impairment in North America but has not been studied in Chinese populations. The aim of this study is to compare consistency of the SLUMS with the Chinese version of Mini-Mental Status Examination (CMMSE) and the Beijing version of Montreal Cognitive Assessment (MoCA-B) in Chinese elderly. METHODS Two hundred seventy-eight Chinese elderly with chronic diseases and geriatric syndromes from the geriatrics department were screened for cognitive impairment, including dementia and mild cognitive impairment, using SLUMS, CMMSE, and MoCA-B. The modified education level cutoff in the diagnostic criteria of SLUMS (mSLUMS) was explored. Scores of the scales and classifications for cognitive status by them were compared using Spearman and κ statistics, respectively. RESULTS Spearman correlation coefficient between scores of the scales were 0.747 (SLUMS vs CMMSE, P < .001), 0.839 (SLUMS vs MoCA-B, P < .001), and 0.773 (CMMSE vs MoCA-B, P < .001). For detection of dementia, κ values were 0.462 (SLUMS vs CMMSE, P < .000) and 0.484 (mSLUMS vs CMMSE, P < .000). For mild cognitive impairment, κ values were 0.123 (SLUMS vs CMMSE plus MoCA-B in parallel, P = .089) and 0.148 (mSLUMS vs CMMSE plus MoCA-B in parallel, P = .031). For all cognitive impairment, κ values were 0.562 (SLUMS vs MoCA-B, P < .000) and 0.650 (SLUMS vs MoCA-B, P < .000). CONCLUSION Findings from our study indicate that the scores of SLUMS are fairly consistent with MoCA-B and CMMSE in Chinese elderly. Discrepancies of classifications for cognitive status by SLUMS and the other 2 scales implies that further work is needed to explore optimal cutoffs of SLUMS for screening mild cognitive impairment and dementia in elderly Chinese.

Abstract
OBJECTIVE To investigate the reversal of multidrug resistance in the cell line HepG2/ADM induced by TNF-alpha. METHODS HepG2/ADM cells were incubated with different concentrations of TNF-alpha (100, 500 and 2500 U/ml) for 72 h. Real-time PCR was performed to compare the mRNA levels of MDR1 with PPAR-alpha in the different concentrations of TNF-alpha treated cells. The Annexin V assay was used to check cell apoptosis induced by 0.5 mg/L adriamycin. Rhodamine 123 efflux assay and MTT assay were used to study P-gp activity and drug resistance in each group, respectively. RESULTS TNF-alpha could induce down-regulation of MDR1 and up-regulation of PPAR-alpha. Meanwhile, it could enhance cell cytotoxicity and cell apoptosis induced by 0.5 mg/L adriamycin. CONCLUSIONS TNF-alpha could partially reverse the multidrug resistance of HepG2/ADM cells by down-regulating the expression of MDR1 and up-regulating the expression of PPAR-alpha.

Abstract
Ischemia-reperfusion injury is responsible for the morbidity associated with liver surgery under total vascular exclusion or after liver transplantation. Recently, it has been reported that mitochondrial K(ATP) channel openers have an effect on myocardial protection via a pharmacological preconditioning action. However, it remains unclear as to whether K(ATP) channel openers can reduce ischemia-reperfusion injury in the liver. The aim of this study was to determine the effects of the mitochondrial K(ATP) channel opener, nicorandil, on ischemia-reperfusion injury in the rat liver. Male Wistar rats were subjected to 73% ischemia for 45 minutes followed by 120 minutes of reperfusion. Nicorandil (3 mg/kg) was orally administered 60 minutes before hepatic ischemia. Nicorandil significantly decreased plasma levels of alanine aminotransferase and lactate dehydrogenase by about 50% and inhibited the remarkably increased TUNEL-positive hepatocytes after reperfusion. Some mediators associated with apoptosis were analyzed by Western blotting. Cytochrome-c and caspase-3 levels in the cytosol increased after reperfusion; nicorandil inhibited the release of cytochrome-c and activation of caspase-3. The expression of Bax and Bcl-2 was significantly increased after reperfusion, being slightly inhibited by the administration of nicorandil. These results suggest that the protective effects of nicorandil against hepatic ischemia-reperfusion injury correlate with the inhibition of mitochondrial cytochrome-c release and caspase-3 activation. These findings demonstrate that nicorandil may become a therapeutic drug for ischemia reperfusion-related liver injury.

Abstract
As experience with laparoscopic cholecystectomy (LC) has increased, so have the number and variety of complications. We report a case of choledocholithiasis caused by migration of a surgical clip applied during LC. A 57-year-old Japanese man who had undergone LC 6 years previously was referred to our hospital with pruritus and jaundice. Magnetic resonance cholangiopancreatography and ultrasonography revealed a solid mass in the common hepatic duct and dilatation of the intrahepatic bile ducts. Abdominal arteriography demonstrated interruption of the right hepatic artery by surgical clips. Five days after a biopsy of the mass was performed through a percutaneous transhepatic biliary drainage tube, the mass moved to the terminus of the common bile duct along with one of the surgical clips. A basket catheter was used to remove the mass via endoscopy. Despite the fact that other clips in the common hepatic duct were partially exposed, the patient has been well for 2 years with no additional interventions.

Abstract
We describe the usefulness of a real-time polymerase chain reaction (PCR) assay for detection of the t(11;14)(q13;q32), most commonly present in mantle cell lymphoma (MCL). This assay is based on the 5'-->3' exonuclease activity of Taq polymerase, which cleaves an internal probe labeled with a reporter dye at its 5' end and a quencher dye at its 3' end during PCR. The real-time t(11;14) PCR assay was established using DNA from a case of MCL with the t(11;14), amplifiable using conventional PCR and primers specific for the major translocation cluster (MTC) region of the bcl-1 locus and the immunoglobulin heavy chain joining region gene (JH). The specificity was determined by analyzing DNA from 82 cases: 50 MCL, 27 other types of non-Hodgkin lymphoma (NHL), and 5 reactive lymphoid proliferations. The real-time t(11;14) PCR results were correlated with data obtained by a conventional PCR assay. By using the real-time assay, bcl-1 MTC/JH DNA fusion sequences were detected in 25 of 50 MCLs but not in other NHLs or reactive lymphoid proliferations. Concordance between real-time and conventional PCR methods for MCL was 96% and for all samples was 98%. The results demonstrate that this real-time PCR method to detect bcl-1 MTC/JH DNA fusion sequences is specific and reliable. In addition, the results are available immediately following amplification, without standard post-PCR manipulations.

Abstract
This study evaluates the utility of fluorescence-based polymerase chain reaction (PCR) and PCR-SSCP methodologies to monitor the clonal relatedness of cells with bcl-2 major break point region (mbr)/JR fusion sequences in sequential samples from patients with follicular lymphoma (FL). Fluorescence-tagged PCR products from 2-4 sequential samples from seven FL patients were resolved in acrylamide gels and analyzed on an Applied Biosystems' automated DNA sequencer equipped with Genescan software. The amplicons were sequenced directly using automated DNA sequencing to obtain the precise amplicon size and base sequence. Fluorescence-based PCR-single-strand conformation polymorphism (SSCP) analysis performed to distinguish amplicons of similar size but of different base sequence. Amplification products differing by as few as 5 bp resolved clearly under fluorescent PCR assay conditions making possible by visual inspection alone the distinction of two products that otherwise appeared to be of similar size by conventional gel electrophoretic methods. The size of the amplicons as determined by Genescan software correlated exactly with the sizes generated by sequence analysis confirming the precision and accuracy of the fluorescent PCR assay. Under nondenaturing conditions, the mobility profiles of the amplicons from sequential samples with identical base sequence remained indistinguishable, whereas amplicons of similar size but of dissimilar base sequence from different patients exhibited distinct migration patterns. Thus, this study demonstrates that a combination of fluorescent PCR and PCR-SSCP assays for the detection of the t(14;18) provides an accurate measure of clonal relationship based on molecular size and sequence similarities without involving radiolabeling and sequencing strategies. Furthermore, the demonstrated preservation of junctional sequences across sequential biopsy specimens validates the use of PCR in the monitoring of minimal residual disease and eliminates concern about the detection of secondary, non-tumor-related translocations.

Abstract
The utility of polymerase-mediated assays in the detection of the t(11;14) involving the bcl-1 major translocation cluster (bcl-1 MTC) was evaluated by analyzing DNA from 33 patients with mantle cell lymphoma, 14 patients with other non-Hodgkin's lymphomas, and five patients with reactive lymphoid hyperplasia. The polymerase chain reaction (PCR) assay was performed using a consensus immunoglobin heavy-chain joining region primer in conjunction with a chromosome 11 specific oligonucleotide primer flanking the translocation site. The sensitivity and specificity of the assay were confirmed by correlation of the (PCR) assay data with restriction analysis. Rearrangements at the bcl-1 MTC were detected in 13 (39%) of 33 cases of mantle cell lymphoma by PCR and in 13 (48%) of 27 cases by restriction analysis. Amplicons were detectable by PCR in 85% (11 of 13) of the cases shown to be bcl-1 rearranged by restriction analysis. Failure to detect amplification products in DNA samples from non-mantle cell lymphomas and reactive follicular hyperplasia further confirmed the specificity of the assay. Sequential hybridization of the PCR products with oligonucleotide probes 3' to the bcl-1 MTC primer revealed that the breakpoints in the bcl-1 MTC were clustered around an Sst I restriction site over a range of 170 base pairs. The study demonstrates that PCR-mediated assay for the detection of the t(11;14) at the bcl-1 MTC is specific and sensitive and can be used as an adjunct to restriction analysis in routine diagnostics.

Abstract
We examined 57 cultured mycobacteria using a method based on polymerase chain reaction (PCR), slot blot hybridization and dideoxy sequencing of nucleotides for detection of M. tuberculosis. Using standard microbiological tests, 34 of 57 specimens were identified as M. tuberculosis and the rest as atypical mycobacteria. Two of 34 specimens that contained M. tuberculosis were not hybridized with a probe specific for M. tuberculosis. These two specimens were identified as atypical mycobacterium by nucleotide sequencing. An atypical mycobacterium specimen that was hybridized with a prove specific for M. tuberculosis was identified as M. tuberculosis using nucleotide sequencing. These results suggest that the approach using PCR and slot blot hybridization for detection of mycobacterium may be more accurate than standard microbiological tests in the rapid and definitive diagnosis of mycobacterial infection.
