Objective The primary aim of the study was to compare two nutritional status evaluation tools:the Patient-Generated Subjective Global Assessment (PG-SGA) and Nutritional Risk Screening (NRS-2002). Using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30 (EORTC QLQ-C30), the second aim was to provide constructive advice regarding the quality of life of patients with malignancy. Methods This study enrolled 312 oncology patients and assessed their nutritional status and quality of life using the PG-SGA, NRS-2002, and EORTC QLQ-C30. Results The data indicate that 6% of the cancer patients were well nourished. The SGA-A had a higher sensitivity (93.73%) but a poorer specificity (2.30%) than the NRS-2002 (69.30% and 25.00%, respectively) after comparison with albumin. There was a low negative correlation and a high similarity between the PG-SGA and NRS-2002 for evaluating nutritional status, and there was a significant difference in the median PG-SGA scores for each of the SGA classifications (P < 0.001). The SGA-C group showed the highest PG-SGA scores and lowest body mass index. The majority of the target population received 2 points for each item in our 11-item questionnaire from the EORTC QLQ-C30. Conclusion The data indicate that the PG-SGA is more useful and suitable for evaluating nutritional status than the NRS-2002. Additionally, early nutrition monitoring can prevent malnutrition and improve the quality of life of cancer patients.

Objective Asthma and chronic obstructive pulmonary disease (COPD) feature different inflammatory and cellular profiles in the airways, indicating that the cellular metabolic pathways regulating these disorders are distinct. Methods We aimed to compare the serum metabolomic profiles among mild persistent asthmatic patients, individuals with stable COPD, and healthy subjects and to explore the potential metabolic biomarkers and pathways. The serum metabolomic profiles of 17 subjects with mild persistent asthma, 17 subjects with stable COPD, and 15 healthy subjects were determined by an untargeted metabolomic analysis utilizing liquid chromatography-mass spectrometry. A series of multivariate statistical analyses was subsequently used. Results Multivariate analysis indicated a distinct separation between the asthmatic patients and healthy controls in electrospray positive and negative ions modes, respectively. A total of 19 differential metabolites were identified. Similarly, a distinct separation between asthma and COPD subjects was detected in the two ions modes. A total of 16 differential metabolites were identified. Among the identified metabolites, the serum levels of hypoxanthine were markedly higher in asthmatic subjects compared with those in COPD or healthy subjects. Conclusions Patients with asthma present a unique serum metabolome, which can distinguish them from individuals with COPD and healthy subjects. Purine metabolism alteration may be distinct and involved in the pathogenesis of asthma.

  Objective  The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.  Methods  The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.  Results  A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).  Conclusion  An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective To estimate the burden of cirrhosis and other chronic liver diseases caused by specific etiologies in China. Methods Data from the Global Burden of Disease Study 2016 (GBD 2016) were used. We evaluated the burden by analyzing age-sex-province-specific prevalence, mortality, and disability-adjusted life-years (DALYs) of 33 provinces in China. Results From 1990 to 2016, prevalence cases in thousands increased by 73.7% from 6833.3 (95% UI: 6498.0–7180.6) to 11869.6 (95% UI: 11274.6–12504.7). Age-standardized mortality and DALY rates per 100,000 decreased by 51.2% and 53.3%, respectively. Male and elderly people (aged ≥ 60 years) preponderance were found for prevalence, mortality, and DALYs. The number of prevalence cases, deaths, and DALYs due to hepatitis C virus (HCV) increased by 86.6%, 8.7%, and 0.9%, respectively. Also, age-standardized prevalence rates decreased in 31 provinces, but increased in Yunnan and Shandong. The Socio-demographic Index (SDI) values were negatively correlated with age-standardized mortality and DALY rates by provinces in 2016; the correlation coefficients were −0.817 and −0.828, respectively. Conclusion Cirrhosis and other chronic liver diseases remain a huge health burden in China, with the increase of population and the aging of population. Hepatitis B virus (HBV) remains the leading cause of the health burden in China.

Objective MicroRNAs (miRs) are attractive molecules to be considered as one of the blood-based biomarkers for neurodegenerative disorders such as Alzheimer's disease (AD). The goal of this study was to explore their potential value as biomarkers for the diagnosis of AD. Methods The expression levels of exosomal miR-135a, -193b, and-384 in the serum from mild cognitive impairment (MCI), dementia of Alzheimer type (DAT), Parkinson's disease with dementia (PDD), and vascular dementia (VaD) patients were measured with a real-time quantitative reverse transcriptase PCR (qRT-PCR) method. Results Both serum exosome miR-135a and miR-384 were up-regulated while miR-193b was down-regulated in serum of AD patients compared with that of normal controls. Exosome miR-384 was the best among the three miRs to discriminate AD, VaD, and PDD. Using the cut-off value could better interpret these laboratory test results than reference intervals in the AD diagnosis. ROC curve showed that the combination of miR-135a, -193b, and-384 was proved to be better than a particular one for early AD diagnosis. Conclusion Our results indicated that the exosomal miRs in the serum were not only potential biomarker of AD early diagnosis, but might also provide novel insights into the screen and prevention of the disease.

Pneumoconiosis, an interstitial lung disease that occurs from breathing in certain kinds of damaging dust particles, is a major occupational disease in China. Patients diagnosed with occupational pneumoconiosis can avail of free medical treatment, whereas patients without a diagnosis of occupational diseases cannot not claim free medical treatment in most provinces from the government before 2019. This study aimed to analyze the priority of medical facility selection and its influencing factors among patients with pneumoconiosis. A total of 1,037 patients with pneumoconiosis from nine provinces in China were investigated. The health service institutions most frequently selected by the patients were county-level hospitals (37.5%). The main reason for the choice was these hospitals’ close distance to the patients’ homes (47.3%). The factors for the choice of health care institutions were living in the eastern region (OR = 2.91), living in rural areas (OR = 2.10), silicosis diagnosis (OR = 2.44), employment in private enterprises (OR = 2.91), smoking (OR = 2.69), and quit smoking (OR = 3.98). The diagnosis, treatment, and rehabilitation therapy of pneumoconiosis should be enhanced in primary medical institutions.

Objective To assess the prevalence of malnutrition among children and adolescents in Xizang (Tibet).
Methods We analyzed data from the Chinese National Survey on Students’ Constitution and Health for the years 1995, 2000, 2005, and 2010 pertaining to Tibetan children and adolescents in Lase (Lhasa), aged 7-18 years old. Numbers of survey subjects for these years were:2 393, 2 754, 2 397, and 2 643, respectively.
Results Our results indicated that the rate of occurrence of stunting in Tibet has evidenced a gradual decline:for boys, from 26.8%in 2000 to 9.3%in 2010;and for girls, from 25.8%in 2000 to 10.8%in 2010. In general, the wasting rate for both boys and girls in Tibet has gradually decreased over time:for boys, from 17.7%in 1995 to 4.6%in 2005;and for girls from 12.5%in 1995 to 2.3%in 2005. The stunting rates of boys aged 7-13 years old and of girls aged 7-11 years old were 67.5%and 53.1%, respectively, while these rates for boys aged 14-18 years old and girls aged 12-18 years old were 32.5%and 46.9%, respectively.
Conclusion Stunting and wasting rates of Tibetan children and adolescents indicate a gradual declining trend over time. The stunting rates of both boys and girls during early puberty were significantly higher than those during late puberty.

  Objective   This study aimed to evaluate the genetic diversity, virulence, and antimicrobial resistance of Aeromonas isolates from clinical patients, tap water systems, and food.   Methods   Ninety Aeromonas isolates were obtained from Ma’anshan, Anhui province, China, and subjected to multi-locus sequence typing (MLST) with six housekeeping genes. Their taxonomy was investigated using concatenated gyrB-cpn60 sequences, while their resistance to 12 antibiotics was evaluated. Ten putative virulence factors and several resistance genes were identified by PCR and sequencing.   Results   The 90 Aeromonas isolates were divided into 84 sequence types, 80 of which were novel, indicating high genetic diversity. The Aeromonas isolates were classified into eight different species. PCR assays identified virulence genes in the isolates, with the enterotoxin and hemolysin genes act, aerA, alt, and ast found in 47 (52.2%), 13 (14.4%), 22 (24.4%), and 12 (13.3%) of the isolates, respectively. The majority of the isolates (≥ 90%) were susceptible to aztreonam, imipenem, cefepime, chloramphenicol, gentamicin, tetracycline, and ciprofloxacin. However, several resistance genes were detected in the isolates, as well as a new mcr-3 variant.   Conclusions   Sequence type, virulence properties, and antibiotic resistance vary in Aeromonas isolates from clinical patients, tap water systems, and food.

  Objective  Epidemiological studies reveal that exposure to fine particulate matter (aerodynamic diameter ≤ 2.5 μm, PM2.5) increases the morbidity and mortality of respiratory diseases. Emerging evidence suggests that human circulating extracellular vesicles (EVs) may offer protective effects against injury caused by particulate matter. Currently, however, whether EVs attenuate PM2.5-induced A549 cell apoptosis is unknown.  Methods  EVs were isolated from the serum of healthy subjects, quantified via nanoparticle tracking analysis, and qualified by the marker protein CD63. PM2.5-exposed (50 μg/mL) A549 cells were pre-treated with 10 μg/mL EVs for 24 h. Cell viability, cell apoptosis, and AKT activation were assessed via Cell Counting Kit-8, flow cytometry, and Western blot, respectively. A rescue experiment was also performed using MK2206, an AKT inhibitor.  Results  PM2.5 exposure caused a 100% increase in cell apoptosis. EVs treatment reduced cell apoptosis by 10%, promoted cell survival, and inhibited the PM2.5-induced upregulation of Bax/Bcl2 and cleaved caspase 3/caspase 3 in PM2.5-exposed A549 cells. Moreover, EVs treatment reversed PM2.5-induced reductions in p-AKTThr308 and p-AKTSer473. AKT inhibition attenuated the anti-apoptotic effect of EVs treatment on PM2.5-exposed A549 cells.  Conclusions  EVs treatment promotes cell survival and attenuates PM2.5-induced cell apoptosis via AKT phosphorylation. Human serum-derived EVs may be an efficacious novel therapeutic strategy in PM2.5-induced lung injury.

  Objective  To investigate the association between blood pressure and all-cause mortality in Shanxi, China.  Methods  The ‘2002 China Nutrition and Health Survey’ baseline data in Shanxi province was used. A retrospective investigation was performed in 2015. The effects of SBP and DBP on the all-cause mortality were analyzed using the Cox regression model. The hazard ratio (HR) and 95% confidence interval (CI) were estimated by the sex and age groups.  Results  The follow-up rate was 76.52% over 13 years, while the cumulative mortality rate for all participants was 917.12/100,000 person-years. The mortality rose with an increasing SBP (χ2trend = 270.537, P < 0.001) or DBP level (χ2trend = 57.240, P < 0.001). After adjustment for the confounding factors, a significant association between mortality and high SBP (≥ 160 mmHg) and high DBP (≥ 100 mmHg), with adjusted HR ranging from 1.405- to 2.179-fold for SBP and 1.550- to 2.854-fold for DBP, was noted. Significant HRs for most DBP subgroups were found in > 60-year-old participants. Males with DBP ≥ 100 mmHg had a significantly higher mortality, with an HR (95% CI) of 2.715 (1.377–5.351).  Conclusion  Adults with SBP > 160 mmHg and DBP > 100 mmHg had a higher mortality risk. Sex and age difference was noted in both DBP and mortality risk.

  Objective  Antimony (Sb) has recently been identified as a novel nerve poison, although the cellular and molecular mechanisms underlying its neurotoxicity remain unclear. This study aimed to assess the effects of the nuclear factor kappa B (NF-κB) signaling pathway on antimony-induced astrocyte activation.  Methods  Protein expression levels were detected by Western blotting. Immunofluorescence, cytoplasmic and nuclear fractions separation were used to assess the distribution of p65. The expression of protein in brain tissue sections was detected by immunohistochemistry. The levels of mRNAs were detected by Quantitative real-time polymerase chain reaction (qRT-PCR) and reverse transcription-polymerase chain reaction (RT-PCR).  Results  Antimony exposure triggered astrocyte proliferation and increased the expression of two critical protein markers of reactive astrogliosis, inducible nitric oxide synthase (iNOS) and glial fibrillary acidic protein (GFAP), indicating that antimony induced astrocyte activation in vivo and in vitro. Antimony exposure consistently upregulated the expression of inflammatory factors. Moreover, it induced the NF-κB signaling, indicated by increased p65 phosphorylation and translocation to the nucleus. NF-κB inhibition effectively attenuated antimony-induced astrocyte activation. Furthermore, antimony phosphorylated TGF-β-activated kinase 1 (TAK1), while TAK1 inhibition alleviated antimony-induced p65 phosphorylation and subsequent astrocyte activation.  Conclusion  Antimony activated astrocytes by activating the NF-κB signaling pathway.
