Study on the correlation between dietary inflammatory index and reflux esophagitis / 中华消化杂志

Objective:To evaluate the correlation between inflammatory diet and reflux esophagitis (RE) with the dietary inflammatory index (DII), and to provide scientific evidence for the prevention and treatment of RE at the level of dietary guidance.Methods:From December 2021 to September 2022, 145 RE patients (RE group) who visited the First Affiliated Hospital of Xinjiang Medical University were recruited. During the same period, 145 subjects who underwent check-ups at the First Affiliated Hospital of Xinjiang Medical University were selected as the healthy control group, and age and gender were matched according to the ratio of 1 to 1. The baseline data of the 2 groups, including body mass index, the history of smoking and drinking, poor dietary habits, and physical activity intensity were collected. Dietary intake of the patients was assessed by a semi-quantitative food frequency questionnaire, and the overall DII was calculated to evaluate the potential anti-inflammatory or pro-inflammatory effects of diet. According to the tertiles of the DII of the healthy control group (33.3% and 66.7% as the cut-off), dietary inflammatory potential was divided into low (<-0.06), moderate (-0.06 to 1.11) and high pro-inflammatory potential diet (>1.11). Logistic regression model was performed to analyze the correlation between DII and RE risk. Linear trend test was used to compare the overall change trend of RE risk OR value along with the increase of DII. Independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Results:The body mass index of RE group was higher than that of healthy control group( (24.11±2.57) kg/m 2 vs. (23.38 ±2.60) kg/m 2), and the difference was statistically significant ( t=-2.41, P=0.017). The proportions of smoking, drinking, over-eating, and eating within 3 h before bedtime of RE group was higher than those of the healthy control group (42.8%, 62/145 vs. 31.0%, 45/145; 31.0%, 45/145 vs. 16.6%, 24/145; 33.1%, 48/145 vs. 17.9%, 26/145; 52.4%, 76/145 vs. 13.1%, 19/145), and the differences were statistically significant ( χ2=4.28, 8.39, 8.78 and 50.86, P=0.039, 0.004, 0.003 and<0.001). While the proportions of night snacking and moderate to severe physical activity of RE group were lower than those of the healthy control group (14.5%, 21/145 vs. 24.1%, 35/145; 22.8%, 33/145 vs.37.2%, 54/145), and the differences were statistically significant ( χ2=4.34 and 7.24, P=0.037 and 0.007). The DII of RE group was higher than that of the healthy control group (1.05 (0.03, 1.62) vs. 0.34(-0.61, 1.35)), and the difference was statistically significant ( Z=8 661.50, P=0.010). Compared with the low pro-inflammatory potential diet, high pro-inflammatory potential diet had a 1.30-fold increased the risk of RE ( OR=2.30, 95% confidence interval (95% CI) 1.29 to 4.09, P=0.005). After adjusting for total energy intake, age, gender, ethnicity, body mass index, education level, and physical activity intensity, the high pro-inflammatory potential diet was still positively correlated with the risk of RE ( OR=2.58, 95% CI 1.16 to 5.76, P=0.020). In the continuous DII, the risk of RE increased by 36% for each 1 increase in DII ( OR=1.36, 95% CI 1.11 to 1.68, P=0.003). After adjusting for major confounding factors, the continuous DII was still positively correlated with the risk of RE ( OR=1.41, 95% CI 1.08 to 1.85, P=0.012; OR=1.42, 95% CI 1.05 to 1.93, P=0.023). The results of trend test showed that the higher the DII, the greater the risk of RE ( P=0.039). Conclusions:Pro-inflammatory diet is correlated with the increased risk of RE, and there is a certain dose-response relationship. Reasonable reduction of the intake of pro-inflammatory food may be beneficial to reduce the risk of RE.

Clinical features and prognosis of core binding factor acute myeloid leukemia children in South China: a multicenter study / 中华儿科杂志

Objective: To analyze the clinical features, efficacy and prognosis factors of core binding factor (CBF) acute myeloid leukemia (AML) children in South China. Methods: This was a retrospective cohort study. Clinical data of 584 AML patients from 9 hospitals between January 2015 to December 2020 was collected. According to fusion gene results, all patients were divided into two groups: CBF-AML group (189 cases) and non-CBF-AML group (395 cases). CBF-AML group were divided into AML1-ETO subgroup (154 cases) and CBFβ-MYH11 subgroup (35 cases). Patients in CBF-AML group chosen different induction scheme were divided into group A (fludarabine, cytarabine, granulocyte colony stimulating factor and idarubicin (FLAG-IDA) scheme, 134 cases) and group B (daunorubicin, cytarabine and etoposide (DAE) scheme, 55 cases). Age, gender, response rate, recurrence rate, mortality, molecular genetic characteristics and other clinical data were compared between groups. Kaplan-Meier method was used for survival analysis and survival curve was drawn. Cox regression model was used to analyze prognostic factors. Results: A total of 584 AML children were diagnosed, including 346 males and 238 females. And a total of 189 children with CBF-AML were included, including 117 males and 72 females. The age of diagnosis was 7.3 (4.5,10.0)years, and the white blood cell count at initial diagnosis was 21.4 (9.7, 47.7)×109/L.The complete remission rate of the first course (CR1) of induction therapy, relapse rate, and mortality of children with CBF-AML were significantly different from those in the non-CBF-AML group (91.0% (172/189) vs. 78.0% (308/395); 10.1% (19/189) vs. 18.7% (74/395); 13.2% (25/189) vs. 25.6% (101/395), all P<0.05). In children with CBF-AML, the CBFβ-MYH11 subgroup had higher initial white blood cells and lower proportion of extramedullary invasion than the AML1-ETO subgroup, with statistical significance (65.7% (23/35) vs. 14.9% (23/154), 2.9% (1/35) vs. 16.9% (26/154), both P<0.05). AML1-ETO subgroup had more additional chromosome abnormalities (75/154), especially sex chromosome loss (53/154). Compared with group B, group A had more additional chromosome abnormalities and a higher proportion of tumor reduction regimen, with statistical significance (50.0% (67/134) vs. 29.1% (16/55), 34.3% (46/134) vs. 18.2% (10/55), both P<0.05). Significant differences were found in 5-years event free survival (EFS) rate and 5-year overall survival (OS) rate between CBF-AML group and non-CBF-AML group ((77.0±6.4)%vs. (61.9±6.7)%,(83.7±9.0)%vs. (67.3±7.2)%, both P<0.05).EFS and OS rates of AML1-ETO subgroup and CBFβ-MYH11 subgroup in children with CBF-AML were not significantly different (both P>0.05). Multivariate analysis showed in the AML1-ETO subgroup, CR1 rate and high white blood cell count (≥50×109/L) were independent risk factors for EFS (HR=0.24, 95%CI 0.07-0.85,HR=1.01, 95%CI 1.00-1.02, both P<0.05) and OS (HR=0.24, 95%CI 0.06-0.87; HR=1.01, 95%CI 1.00-1.02; both P<0.05). Conclusions: In CBF-AML, AML1-ETO is more common which has a higher extramedullary involvement and additional chromosome abnormalities, especially sex chromosome loss. The prognosis of AML1-ETO was similar to that of CBFβ-MYH11. The selection of induction regimen group FLAG-IDA for high white blood cell count and additional chromosome abnormality can improve the prognosis.

Clinical characteristics and drug efficacy evaluation of voltage-gated potassium channel-related genetic epilepsy / 中国药理学通报

Aim To analyze the genotype-phenotype characteristics of voltage-gated potassium channels (Kv) associated genetic epilepsy and evaluate the efficacy of anti-seizure medications(ASMs). Methods PubMed database was searched and patients meeting the inclusion criteria were included for analysis. We divided the patients into “benign”, “encephalopathic” and other phenotypes according to the clinical characteristics. We performed descriptive statistical analysis of patients' mutated genes, clinical phenotype and drug efficacy, and used logistic regression to explore the influencing factors of treatment outcome. Results Data of 474 children were included for analysis. There were significant differences among different phenotypes in mutated genes, source of mutations and so on. In terms of clinical characteristics, there were also significant differences between patients with different phenotypes in age of onset, combined developmental delay and so on. In terms of monotherapy, phenobarbital was the most common treatment choice for children with “benign” phenotype, and sodium channel blockers (SCBs) were the most common treatment choice for children with “encephalopathy” phenotype, and the efficacy of SCBs monotherapy was superior to that of other ASMs. Multivariate Logistic analysis of the children receiving monotherapy showed that whether the children were combined with developmental delay and whether SCBs were used were significant factors influencing the efficacy of drug therapy. Conclusions Patients with the “benign” and “encephalopathic” phenotypes differ in several aspects of genetic variation, clinical characteristics, and drug selection. These results suggest that SCBs may be one of the recommended options for monotherapy.

Multivariate logistic regression was used to analyze the independent risk factors of UC with TE. Independent sample t test, Mann-Whitney U test, Chi-square test or Fisher′s exact probability method were used for statistical analysis. Results:Among the 46 cases of UC with TE, 14 cases (30.4%) had single site venous TE, mainly venous thrombosis of lower limbs; 20 cases (43.5%) had single site arterial TE, mainly myocardial infarction and cerebral infarction; 12 cases (26.1%) had multi-site TE. The proportion of patients with hypertension history and with severe active period of UC, and the levels of D-dimer, FDP, ESR and CRP in patients with UC with TE were all higher than those in patients without comorbidities(52.2%, 24/46 vs.33.7%, 31/92, 45.7%, 21/46 vs.19.6%, 18/92, (822.03±654.33) μg/L vs.(230.28±225.62) μg/L, 5.77 mg/L(6.87 mg/L) vs. 2.10 mg/L(1.55 mg/L), (46.32±28.27) mm/1 h vs.(33.08±24.30) mm/1 h, 22.05 mg/L(46.42 mg/L) vs. 5.58 mg/L(11.58 mg/L)); the hospital stay and PT were longer than those in patients without comorbidities ((12.76±10.18) d vs.(8.66±4.89) d, (14.13±6.06) s vs.(11.86±1.42) s); the Hb and MPV were lower than those in patients without comorbidities ((110.91±31.38) g/L vs.(123.83±27.67) g/L, (9.60±0.94) fL vs.(10.04±1.16) fL; and the differences were statistically significant( χ2=4.37 and 10.29, t=-5.96, Z=-5.78, t=-2.85, Z=-3.87, t=-2.58, -2.50, 2.47 and 2.47; all P<0.05). The results of multivariate logistic regression analysis showed that severe activity period of UC ( OR=3.079, 95% confidence interval (95% CI) 1.100 to 8.615), hypertension history ( OR=4.454, 95% CI 1.467 to 13.519), and D-dimer level( OR=1.003, 95% CI 1.001 to 1.005) were all independent risk factors of UC with TE(all P<0.05). Conclusions:Lower extremity venous, myocardial infarction and cerebral infarction are common in UC with TE. Severe activity period of UC, history of hypertension and D-dimer level are independent risk factors of UC with TE. These above factors should be paid attention to and corresponding prevention should be taken.

Oral sulfate solution versus polyethylene glycol for colonoscopy bowel preparation: a randomized controlled study in phase Ⅲ / 中华消化内镜杂志

Objective:To compare the efficacy of oral sulfate solution (OSS) and polyethylene glycol (PEG) electrolyte powder for colonoscopy bowel preparation.Methods:A total of 283 randomized patients from 9 centers in China taking OSS ( n=143) or PEG ( n=140) using two-day split bowel preparation regimen received colonoscopy and assessment. The primary index was the bowel preparation success rate [global Boston bowel preparation scale (BBPS)≥ 6 by independent assessment center]. Secondary indices included BBPS global and segmental scores, investigator satisfaction (5-point Likert scale) with the quality of bowel preparation, patient satisfaction assessed by questionnaires, and patient tolerance assessed by Sharma scale. Compliance and safety were compared between the two groups. Results:The bowel preparation success rates were 100.0% for OSS and 99.3% for PEG [adjusted difference 0.7% (95% CI: -5.3% - 6.7%), P<0.001 for non-inferiority]. The BBPS global score in OSS group was significantly higher than that in PEG group (8.1 VS 7.7, P<0.001). The segment BBPS scores were also higher in OSS group than those in PEG group for all 3 segments (right colon: 2.4 VS 2.3, P=0.002; transverse colon: 2.8 VS 2.7, P=0.018; left colon: 2.8 VS 2.7, P=0.007). Investigator Likert score in the OSS group was significantly higher than that in the PEG group (2.6 VS 2.3, P<0.001). There was no significant difference in compliance between OSS and PEG, except for the second dose (90.9% VS 82.6%, P=0.039). There was no significant difference in patient satisfaction, Sharma score or proportion of patients with tolerance-related symptoms between the two groups. Safety was comparable between the two groups, and all adverse events were mild to moderate. Conclusion:OSS has comparable efficacy with PEG, with higher BBPS scores in all segments, better investigator satisfaction, better compliance in split dose, and comparable patient tolerance and safety.

Enzyme-instructed and mitochondria-targeting peptide self-assembly to efficiently induce immunogenic cell death

Immunogenic cell death (ICD) plays a major role in cancer immunotherapy by stimulating specific T cell responses and restoring the antitumor immune system. However, effective type II ICD inducers without biotoxicity are still very limited. Herein, a tentative drug- or photosensitizer-free strategy was developed by employing enzymatic self-assembly of the peptide F-pY-T to induce mitochondrial oxidative stress in cancer cells. Upon dephosphorylation catalyzed by alkaline phosphatase overexpressed on cancer cells, the peptide F-pY-T self-assembled to form nanoparticles, which were subsequently internalized. These affected the morphology of mitochondria and induced serious reactive oxygen species production, causing the ICD characterized by the release of danger-associated molecular patterns (DAMPs). DAMPs enhanced specific immune responses by promoting the maturation of DCs and the intratumoral infiltration of tumor-specific T cells to eradicate tumor cells. The dramatic immunotherapeutic capacity could be enhanced further by combination therapy of F-pY-T and anti-PD-L1 agents without visible biotoxicity in the main organs. Thus, our results revealed an alternative strategy to induce efficient ICD by physically promoting mitochondrial oxidative stress.

Effect of Curcumin on Biological Behavior of Gastric Cancer Cells Through miR-539 / 胃肠病学

Background: Studies have shown that curcumin can regulate the expressions of a variety of miRNAs and affect tumor cell biological behavior. However, whether curcumin affects the biological behavior of gastric cancer cells by regulating expression of miR-539 has not been clarified. Aims: To investigate the effect and mechanism of curcumin on proliferation, migration, invasion, apoptosis of gastric cancer cells by regulating the expression of miR-539. Methods: A total of 49 gastric cancer tissue specimens were collected. Gastric cancer AGS, SGC7901 cells were divided into blank group, curcumin group, negative control group, miR-539 mimics group, miR-539 inhibitor group, inhibitor control group, miR-539 inhibitor +curcumin group. qRT-PCR was used to detect the mRNA expression of miR-539 in gastric cancer tissue and cells. Cell proliferation was detected by MTT. Scratch test, Transwell test were used to detected cell migration and invasion. Cell apoptosis was determined by flow cytometry. Western blotting was used to detect protein expressions of APOBEC3B, c-Myc, cyclin D1, claudin-1 and N-cadherin. Results: Expressions of miR-539 mRNA in gastric cancer tissue and gastric cancer cells were significantly decreased than those in corresponding controls (P<0.05), and was related to tumor stage in gastric cancer patients (P<0.05). Curcumin up-regulated the expression of miR-539 mRNA in a dose-dependent manner (P<0.05). Compared with corresponding control group, cell proliferation, migration and invasion were significantly decreased in miR-539 mimics group and curcumin group (P<0.05), cell apoptosis rate was significantly increased (P<0.05), and protein expressions of APOBEC3B, c-Myc, cyclin D1, claudin-1 and N-cadherin were significantly decreased (P<0.05). Conclusions: Expression of miR-539 is decreased in gastric cancer, and curcumin can inhibit proliferation, migration and invasion of gastric cancer cells and induce cell apoptosis by up-regulating the expression of miR-539.

Effects of sarcopenia on the risks of osteoporosis and fragility fractures among community-dwelling middle and old age people: a systematic review and meta-analysis / 中华临床营养杂志

Objective To explore the relationship between sarcopenia and the risks of osteoporosis and fragility fractures among community-dwelling middle and old people (≥50 years) . Methods OVID/Medline, Pubmed, EMBASE, Cochrane Library, Web of Science ( SCI ) , China National Knowledge Infrastructure ( CNKI) , and Chinese WanFang Database were searched systematically for literatures related to the relationship between sarcopenia and osteoporosis and fragility fractures from January 1987 to July 2018. The searched litera-tures were screened based on the inclusion and exclusion criteria. The quality of the literatures were evaluated by using the risk assessment tool NOS ( Newcastle-Ottawa Scale) and AHRQ ( Agency for Healthcare Research and Quality) . Meta-regression analysis was used to explore the cause of heterogeneity between studies. The sub-group analysis was used to assess the differences in the risk of osteoporosis based on the important characteristic variables, such as gender, ethnicity, age, diagnostic criteria of sarcopenia, and outcome type. Sensitivity anal-ysis and trim and fill method were conducted to test the stability of the results of this Meta-analysis. Data col-lected and summarized by Stata 12. 2 software. Results A total of 23 studies in line with quality requirements were included eventually, including 56, 544 subjects. The results of this Meta-analysis were relatively robust. Compared with non-sarcopenia, the relative risk ( RR ) for osteoporosis among subjects with sarcopenia was 1. 61 (95％ CI: 1. 42～1. 82, P<0. 00001). Especially, compared with postmenopausal women RR=1. 37 (95％ CI: 1. 23-1. 53, P<0. 0001) and yellow race RR=1. 53 (95％ CI: 1. 34-1. 75, P<0. 0001), sar-copenia had a higher impact trend on the risk of osteoporosis in older men RR=2. 26 ( 95％ CI: 1. 71-2. 98, P<0. 0001 ) and Caucasian RR = 2. 03 ( 95％ CI: 1. 46-2. 81, P<0. 0001 ) . Conclusion Among community-dwelling middle and old aged people (≥50 year) , sarcopenia increases the risk of osteoporosis and fragility fracture by 61％ and 59％ -61％ significantly, respectively. Middle and old aged people should be pre-vented and screened early for sarcopenia, which attributes to identify high risk groups of fragile fractures and re-duce the risk of adverse outcomes.

Clinical and genetic analyses of juvenile myelomonocytic leukemia / 中国当代儿科杂志

OBJECTIVE@#To study the clinical and genetic features of juvenile myelomonocytic leukemia (JMML) and the association between genotype and prognosis. Methods The clinical data of 15 children who were diagnosed with JMML were collected. Next-generation sequencing was used to detect common gene mutations of JMML.@*RESULTS@#The male/female ratio was 6.5:1, and the age of onset was 19 months (range 2-67 months). Of the 15 children, 11 (73%) experienced disease onset before the age of 4 years, with abdominal distension and pyrexia as initial symptoms. All children had hepatosplenomegaly and superficial lymphadenectasis, with a number of peripheral blood mononuclear cells of >1.0×10/L and a percentage of juvenile cells of 1%-7% in peripheral blood smear. The percentage of bone marrow blasts + juvenile cells was <20%, and the percentage of monoblasts + promonocytes was 1%-10%. Of the 15 children, 10 (67%) had a higher level of hemoglobin F than the normal level at the corresponding age, with the highest level of 62.5%. All 15 children had the absence of Philadelphia chromosome, and one child had chromosome 7 deletion. All 15 children had a negative result of BCR/ABL fusion gene detection. PTPN11 gene mutation was found in 5 children (33%), NF1 mutation in 4 children (27%), CBL mutation in 3 children (20%), and RAS mutation in 3 children (20%). No children received regular chemotherapy, and one child underwent hematopoietic stem cell transplantation. The median follow-up time of 15 children was 18 months (range 1-48 months). Among the 15 children, 8 died (among whom 4 had PTPN11 gene mutation, 3 had NF1 mutation, and 1 had RAS mutation) and 7 survived. The children with PTPN11 mutation had the worst prognosis and the highest mortality rate, and those with CBL or NRAS mutation had a relatively good prognosis. The level of hemoglobin F was negatively correlated with survival time (r=-7.21, P=0.002).@*CONCLUSIONS@#In children with JMML, the type of gene mutation is associated with prognosis. The children with PTPN11 mutation often have a poor prognosis, and those with CBL or NRAS mutation have a relatively good prognosis.

Clinical Significance of CRLF2 High Expression in Bone Marrow Mononuclear Cells from Children with Acute Lymphoblastic Leukemia / 中国实验血液学杂志

OBJECTIVE@#To detect the expression of CRLF2 in bone marrow mononuclear cells from children with newly diagnosed acute lymphoblastic leukemia(ALL) and to explore its clinical significance in pediatric ALL.@*METHODS@#A total of 218 children with newly diagnosed ALL who achieveal the complete remission and had the complete follow-up information were selected, and the expression level of CRLF2 in bone marrow mononuclear cells of these children was detected by real-time fluorescent quantitative PCR, and the significance of CRLF2 expression level in clinical prognosis of ALL children was analyzed by using statistical method.@*RESULTS@#28 cases in 218 children with complete data showed high expression of CRLF2. The cumulative recurrence rate in the CRLF2 high expression group was significantly higher than that in the low expression group (53.6% vs 12.6%) (P＜0.01). The predicted 5-year recurrence-free survival rate (RFS) of ALL children with CRLF2 high expression was significantly higher than that of low expression group (P＜0.01). There was no significant difference in the predicted 5-year RFS between ALL children with CRLF2 low and high expression in the standard-risk(SR) group (P＞0.05). The predicted 5-year RFS of ALL children with CRLF2 low expression was higher than that of ALL children with CRLF2 high expression in the intermediate-risk (IR) and high-risk (HR) groups. (P＜0.05). Cox analysis showed that CRLF2 high expression is an independent risk factor for the relapse of children with ALL.@*CONCLUSION@#The recurrence rate of pediatric ALL with CRLF2 high expression is high, and CRLF2 high expression is an important prognostic factor for high risk of relapse in ALL children with IR and HR. It is necessary to use CRLF2 expression as an indicator of risk stratification in pediatric ALL.

Influence of genetic polymorphisms in drug metabolism enzymes and transporters on pharmacokinetics of different fluvastatin formulations / 中国药理学与毒理学杂志

OBJECTIVE The purpose of the present study was to investigate the impact of fluvas-tatin formulation on the pharmacokinetics-genetic polymorphis relationship. METHODS We compared the difference between the pharmacokinetics of fluvastatin as an extended-release (ER) 80 mg tablet and an immediate-release(IR)40 mg capsule in terms of drug metabolism enzyme and transporter ge-netic polymorphisms. In this open-label, randomized, two-period, two-treatment, crossover study, ef-fects of BCRP, SLCO1B1, MDR1, CYP2C9, and CYP3A5 polymorphisms on the pharmacokinetics of fluvastatin were analyzed in 24 healthy individuals.Each treatment duration was 7 days with a washout period of 7 days between the crossover.Serum concentration of fluvastatin was evaluated using high-performance liquid chromatography-tandem mass spectrometry. RESULTS The SLCO1B1 T521C genotype had no statistically significant effect on IR 40 mg capsule of fluvastatinafter single or repeated doses.However,for the ER 80 mg tablet,the SLCO1B1 T521C genotype correlated with the AUC0-24of repeat doses (P=0.01). The CYP2C9*3 genotype correlated with the AUC0- 24after the first dose IR 40 mg capsule (P<0.05); however, the difference between CYP2C9*1/*1 and CYP2C9*1/*3 was not statistically significant after repeated doses. CONCLUSION The effect of SLCO1B1 T521C on fluvas-tatin exposure was observed and was more profound in ER and repeated dose administration than in IR and single dose administration.We recommend that formulation should be incorporated into future pharmacogenomics studies and clinical implication guidelines.

Impact of sarcopenia on the risk of falls, osteoporosis, fractures, and all causes of death among elderly people: A Meta-analysis of prospective cohort studies / 中华临床营养杂志

Objective To explore the relationship between sarcopenia and the risks of falls, osteoporo-sis, fractures and all-cause mortality among elderly people. Methods This was a meta-analysis of prospective cohort studies. Databases of OVID/Medline, PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure ( CNKI) and Chinese WanFang Database were searched systematically according to the inclusion and exclusion criteria. The literatures related to the relationship between sarcopenia and falls, os-teoporosis, fractures and all-cause mortality among elderly people from January 1987 to June 2017 were identi-fied. The quality of the literature was evaluated by the risk assessment tool Newcastle-Ottawa Scale recommen-ded by the Cochrane. Meta-analysis was conducted by RevMan 5. 3 and Stata 12. 1 software. Results Totally 13 prospective cohort studies including 19 376 subjects and 3 190 outcome events were entered in meta-analysis. The relative risk ( RR) for comprehensive adverse outcome events among subjects with sarcopenia was 1. 64 times of non-sarcopenia subjects (95% CI=1. 51-1. 78, P<0. 000 01), and the RRs for fall, osteoporosis, fractures and all-cause mortality were 1. 60 (95% CI=1. 42-1. 81, P<0. 000 01), 4. 85 (95% CI=2. 18- 10. 79, P=0. 000 1), 1. 59 (95% CI=1. 40-1. 80, P<0. 000 01), 2. 08 (95% CI=1. 18-3. 69, P=0. 01) times of non-sarcopenia subjects respectively. Conclusion Sarcopenia increases the risk of falls, fractures, all-cause mortality and comprehensive adverse outcome significantly, suggesting that sarcopenia might be a pre-dictor for adverse outcomes among elderly people.
