ABSTRACT
ObjectiveHair is an essential skin appendage, primarily composed of keratins and keratin-associated proteins. The protein composition and proportion of hair samples vary among different races and sexes. Currently, there is a lack of efficient methods to extract hair proteins. This study aims to explore the application of quantitative hair proteomics in distinguishing individual hair characteristics. MethodsBased on the exploration of sample processing and lysis buffer using three hair samples, we developed a stable and efficient hair protein extraction method, named PLEE (PTM lab for protein extraction from hair with high efficiency). We used the PLEE method to extract seven human hair samples and performed proteomic experiments on them using in-gel digestion method to produce data for analyzing hair protein composition and proportion among individuals. ResultsA total of 274 proteins were identified, among which 107 proteins were commonly present, and the number of non-common proteins ranged from 57-119, with some samples having unique identification proteins. Using the 107 commonly identified proteins for quantitative protein fractionation analysis, various samples were distinguished by clustering and principal component analysis, and technical repeated samples were merged, indicating the stability of the process. In addition, 10 key proteins (KRT33A, KRTAP9-6, KRT83, KRTAP7-1, KRT32, BLMH, KRT38, KRTAP11-1, NPAS1, KRTAP4-3) with large differences between individuals and stable protein identification within the same individual were screened. ConclusionThe protein composition of hair varies among different individuals, and the 10 selected proteins are expected to be key proteins for distinguishing individual hair characteristics and have significant potential applications in individual identification and criminal investigation.
ABSTRACT
To explore the changes and the reaction mechanisms between soil microecological environment and the content of secon-dary metabolites of plants under water deficit, this study carried out a pot experiment on the 3-leaf stage seedlings of Rheum officinale to analyze their response mechanism under different drought gradients(normal water supply, mild, moderate, and severe drought). The results indicated that the content of flavonoids, phenols, terpenoids, and alkaloids in the root of R. officinale varied greatly under drought stresses. Under mild drought stress, the content of substances mentioned above was comparatively high, and the content of rutin, emodin, gallic acid, and(+)-catechin hydrate in the root significantly increased. The content of rutin, emodin, and gallic acid under severe drought stress was significantly lower than that under normal water supply. The number of species, Shannon diversity index, richness index, and Simpson index of bacteria in the rhizosphere soil were significantly higher than those in blank soil, and the number of microbial species and richness index decreased significantly with the aggravation of drought stresses. In the context of water deficit, Cyanophyta, Firmicutes, Actinobacteria, Chloroflexi, Gemmatimonadetes, Streptomyces, and Actinomyces were the dominant bacteria in the rhizosphere of R. officinale. The relative content of rutin and emodin in the root of R. officinale was positively correlated with the relative abundance of Cyanophyta and Firmicutes, and the relative content of(+)-catechin hydrate and(-)-epicatechin gallate was positively correlated with the relative abundance of Bacteroidetes and Firmicutes. In conclusion, appropriate drought stress can increase the content of secondary metabolites of R. officinale from physiological induction and the increase in the association with beneficial microbe.

ABSTRACT
Objective::To establish differential metabolites between different varieties of Angelica sinensis, and provide reference for breeding, introduction, regional cultivation and ecological cultivation of new varieties of A. sinensis. Method::Comprehensive non-target metabonomics analysis was conducted for five new varieties of A. sinensis collected at the same time from the same origin: Mingui No. 1 (MG1), Mingui No. 2 (MG2), Mingui No. 4 (MG4), Mingui No. 5 (MG5), and Mingui No. 6 (MG6). The 50% methanol extract of each variety was taken, and then the differential metabolites among varieties were found by using ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS), software Progenesis QI, principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), and non-targeted metabonomics analysis. Differential metabolites were identified based on precise molecular weight, secondary fragments, KEGG database, HMDE database and related literature information. Result::The results of UPLC-Q-TOF-MS and multivariate statistical analysis showed that there were significant differences in the metabolites of five Angelica varieties. As compared with MG1, the contents of chlorogenic acid, ferulic acid, tryptophan and ferulic aldehyde were significantly lower in MG2, MG4, MG5 and MG6, while the contents of ligustilide, coumarin, bovine keratin, palmitin, protocatechualdehyde and linolenic acid were significantly higher (P<0.05). The results of multivariate statistical analysis showed that the metabolites of MG2 and MG5 were similar with those of MG6, but were significantly different from those of MG4.In addition, 38 distinct metabolites were identified, involving 7 potential targeted metabolic pathways. Different varieties of A. sinensis could regulate the synthesis of their metabolites through phenylpropanoid biosynthesis and sesquiterpene-like compounds metabolism, lipid metabolism, amino acid metabolism, carbohydrate metabolism, nucleotide metabolism, carotenoids, linolenic acid, linoleic acid and some other metabolic pathways. Conclusion::UPLC-Q-TOF-MS and Progenesis QI metabonomics techniques were used to compare the chemical constituents of different varieties of A. sinensis from the overall level. The differences and their regularities were found, which could provide reference for quality control, variety sorting, identification, breeding and ecological planting of A. sinensis.
ABSTRACT
OBJECTIVE@#To study the correlation of plasma vitamin A (VitA) levels between neonates and pregnant women in third trimester.@*METHODS@#A total of 688 pregnant women were recruited in Yuanshi and Laoting counties of Hebei Province, from May to June 2009. Venous blood samples of women before delivery and cord blood samples of newborns were collected and measured for retinol (retinol concentration was used to reflect VitA level) using high performance liquid chromatography assay. According to venous blood plasma retinol concentration, maternal VitA nutritional status was divided into deficiency (<0.70 μmol/L), marginal deficiency (0.70-<1.05 μmol/L), and sufficiency (≥1.05 μmol/L). According to cord blood plasma retinol concentration, neonatal VitA nutritional status was divided into deficiency (<0.35 μmol/L), marginal deficiency (0.35-<0.70 μmol/L), and sufficiency (≥0.70 μmol/L); neonatal VitA relative deficiency was further defined as cord blood plasma retinol concentration lower than the 10th percentile. VitA placental transport ratio was defined as retinol concentration in the neonates divided by that in pregnant women. Multivariable fractional polynomials (MFP) model and Pearson correlation were used to study the dose-response relationship between maternal and neonatal plasma VitA levels, Logistic regression model to estimate the effect of maternal VitA nutritional status on neonatal VitA deficiency, and MFP model and Spearman correlation to describe the relationship between maternal VitA level and VitA placental transport ratio.@*RESULTS@#The average retinol concentration of the pregnant women was (1.15±0.30) μmol/L, and the prevalence of VitA deficiency and marginal deficiency were 4.5% and 37.8%, respectively. Average retinol concentration of the neonates was (0.78±0.13) μmol/L, and no neonates were VitA deficiency, 28.2% of the neonates were marginal deficiency. After multivariable adjustment, the VitA level of the neonates was positively and linearly related to maternal VitA level (pm=1, P<0.05), with the corresponding Pearson correlation coefficient of 0.13 (P<0.01). As compared with the women with sufficient VitA, those with VitA deficiency (crude OR=2.20, 95%CI:1.04-4.66) and marginal deficiency (crude OR=1.43, 95%CI:1.01-2.02) had higher risks to deliver neonates with VitA marginal deficiency; while the risks turned to be non-significant after multivariable adjustment. The pregnant women with VitA deficiency had higher risk to deliver neonates with relative VitA deficiency before and after multivariable adjustment (crude OR=3.02, 95%CI:1.21-7.50; adjusted OR=2.76, 95%CI:1.05-7.22). The maternal VitA level was negatively and non-linearly correlated with placental transport ratio (pm= -0.5, P<0.05), with corresponding adjusted Spearman correlation coefficient of -0.82 (P<0.001).@*CONCLUSION@#There was a positive linear dose-response relationship between VitA levels of newborns and pregnant women in third trimester, indicating that neonatal VitA storing levels at birth was affected by maternal VitA nutritional status.

ABSTRACT
Objective This study aimed to analyze the differences in the molecular characteristics of transcriptome between esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC). Methods We obtained transcriptomic data on ESCC and EAC from the TCGA database, screened differentially expressed mRNAs, lncRNAs and miRNAs in cancer and the adjacent tissues, and constructed a network of ESCC- and EAC-related competitive endogenous RNA (ceRNA). We predicted the target genes and performed gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses on important miRNAs, and compared the molecular features of the transcriptomes between ESCC and EAC. Results The ceRNA network analysis showed that PVT1, LINC00524, miR-204, miR-383, HOXC8 and NTRK2 played important regulatory roles in both ESCC and EAC. Totally, 13 227 regulatory target genes were predicted with miR-204-5p via miRWalk and 232 target genes screened from the miRDB database. GO analysis revealed 38 enrichments, mainly involved in the regulation of cell-matrix adhesion, morphogenesis of cell membrane projection, and β-catenin combination, KEGG analysis showed 4 relevant pathways: the hedgehog, life-regulating, estrogen and relaxin signaling pathways, and survival analysis manifested LINC00261, MLIP-IT1 and LINC00504 as survival-related differentially expressed lncRNAs, hsa-mir-338 as differentially expressed miRNA, but no mRNA in ESCC. Survival-related differentially expressed lncRNAs in EAC included CYP1B1-AS1 and HOTAIR, and differentially expressed mRNAs included IL11, NTRK2, ANGPT2 and PBK. Of the differentially expressed lncRNAs in both ESCC and EAC, 150 (15.4%) were up-regulated and 158 (26.8%) down-regulated; of the miRNAs, 22 (24.2%) up-regulated and 8 (27.6%) down-regulated; and of the mRNAs, 234 (20.5%) up-regulated and 418 (23.7%) down-regulated. Conclusion There are significant molecular differences between ESCC and EAC, and the differentially expressed lncRNA, miRNA and mRNA may provide some new targets and molecular markers for the treatment and prognosis of esophageal carcinoma.
ABSTRACT
OBJECTIVE@#To describe the birth characteristics for Chinese newborns, to assess the feasibility of collecting basic data on maternal and child health, and to conduct relevant epidemiological studies by using mobile terminals.@*METHODS@#From June 2016 to January 2017, pregnant women who delivered in hospitals were recruited in 166 hospitals scattered across 23 provinces of China. The data on their maternal and child health including delivery mode, gestational age and birth weight, were collected by self-administered questionnaires embedded in a mobile application. The incidences or means of cesarean section, preterm birth, birth weight, length and head circumference were calculated and compared with recognized national data, including 2005 Growth Standards for Chinese Children Under 7 Years of Age, 2006 World Health Organization Child Growth Standards and 2014 Chinese Neonatal Birth Weight Standards by Gestational Age.@*RESULTS@#A total of 9 986 women were investigated, among whom those aged ≥35 years accounted for 11.7% and those received well education (college and above) accounted for 70.2%. The rate of cesarean section, preterm delivery, low birth weight and macrosomia were 38.1%, 4.5%, 2.2%, and 7.8%, respectively. The means were (3.33±0.44) kg [male (3.36±0.44) kg, female (3.29±0.43) kg] for birth weight, (50.97±2.32) cm [male (51.04±2.32) cm, female (50.89±2.32) cm] for birth length, and (33.99±1.56) cm [male (34.01±1.57) cm, female (33.97±1.55) cm] for head circumference, respectively. As compared with the national data, the cesarean section rate and birth weights by gestational age for term-born neonates were similar to the latest national data in 2014, while the means of birth weight and length were obviously higher than those of the 2005 Growth Standards for Chinese Children Under 7 Years of Age and 2006 World Health Organization Child Growth Standards.@*CONCLUSION@#As compared with the national data 10 years ago, the mean birth weights for male and female newborns were increased by 40 g and 80 g respectively and mean lengths by 0.6 cm and 1.3 cm, but changes for mean head circumferences were negligible, indicating that the physical health condition for Chinese newborns improved significantly over past 10 years and emerging information technology likely provided a new approach for epidemiological research.

ABSTRACT
Objective The aim is to understand the underestimation of body weight status and its associated factors among overweight and obese adults in China. Methods Nationally representative data were collected in 2013 by the China Chronic Disease and Risk Factor Surveillance which used a multistage stratified cluster sampling method. A total of 87 552 overweight and obese adults aged ≥18 years old were included. Demographic characteristics, weight perception and disease status were obtained from in-person interviews. Height, weight and blood pressure were measured through physical examination. Venous blood samples were obtained and assayed for fasting plasma glucose, 2-hour oral glucose tolerance test, total cholesterol, triglycerides, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Complex sampling was weighted and multiple logistic regression models were used for analyzing. Results Among overweight and obese adults, 74.7% (95% CI: 73.3%-76.1%) underestimated their weight status. The mild underestimation rate was 60.7% (59.6%-61.7%) while the severe was 14.0% (13.1%-14.9%). The aged, low education level, low annual income, rural area and obesity were risk factors for both weight status underestimation and severe underestimation (all P<0.05). Awareness of having hypertension and dyslipidemia were protective factors (all P<0.05). Conclusions Most overweight and obese adults in China underestimated their own weight status, which was affected by age, education and income level, awareness of having chronic diseases and other factors. Targeted interventions should be carried out for different characteristic groups.
ABSTRACT
Objective: To investigate the serum expression and influencing factors of hepcidinin patients with classical paroxysmal nocturnal hemoglobinuria (PNH) . Methods: Retrospective analysis of 36 classical PNH patients from 2016.3 to 2017.3. Serum hepcidin concentration was measured by ELISA method. The relationship between serum hepcidin concentration and erythropoiesis and iron homeostasis parameters was evaluated. Results: The median serum hepcidin level of 36 classical PNH patients was 32.03 (23.11, 118.48) μg/L, it was significantly lower than of 181.42 (106.80, 250.53) μg/L in 292 normal control subjects (z=-5.107, P<0.001) . The median serum hepcidin of 56.41 (44.60, 95.06) μg/L in PNH patients with normal ferritin was significantly lower than that in normal controls. The median serum hepcidin concentration 23.75 (21.77, 30.35) μg/L in iron deficiency PNH patients was lower than that in the normal ferritin PNH patients. However, the median serum hepcidin level of classical PNH with elevated ferritin patients 336.19 (304.19, 375.08) μg/L was significantly higher not only than that of normal ferritin and iron deficiency PNH ones, but also than that of normal control subjects. Regression analysis showed that serum ferritin, transferrin saturation and serum albumin level were independent influencing factors of serum hepcidin level in patients with classical PNH. Conclusion: The decreased serum hepcidin level in patients with classical PNH was mainly influenced by iron metabolism factors.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the value of neutrophil-monocyte product (NMP) combined with serum creatinine (Scr) in the assessment of the severity of acute pancreatitis (AP).</p><p><b>METHODS</b>The clinical data of 120 Uighur patients with AP were retrospectively analyzed, including 104 with non-severe AP (non-SAP group) and 16 with severe AP (SAP group). The correlation of NMP combined with Scr with ICU admission and in-hospital death were analyzed. The receiver operating characteristic (ROC) curves were plotted to compare the efficiency of acute physiology and chronic health evaluation (APACHE-II), neutrophil-lymphocyte ratio (NLR) and NMP combined with Scr in determining the severity of AP.</p><p><b>RESULTS</b>The levels of NMP and Scr were significantly higher in SAP group than in non-SAP group within 24 h after admission (P=0.012; P<0.001). NMP combined with Scr was positively correlated with ICU admission (r=0.489, P<0.001) and in-hospital death (r=0.383, P<0.001). No significant difference was found in the area under curve (AUC) between APACHE-II and NMP combined with Scr for determining AP severity (Z=0.38, P=0.704), but they both were superior to NLR (Z=3.10, P=0.002; Z=2.43, P=0.016).</p><p><b>CONCLUSION</b>NMP combined with Scr can be a simple and effective indicator for determining the severity of AP.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To compare the risk factors associated with serrated polyps (SPs) and conventional adenoma (CA).</p><p><b>METHODS</b>One hundred and three healthy control subjects, 100 patients with pathologically confirmed SPs and 115 with CA were randomly selected from individuals undergoing colonoscopy in Nanfang Hospital from 2012 to 2015. The demographic and clinical data were collected from the subjects, including age, gender, height, weight, hypertension, diabetes, smoking status, alcohol use, family history of colorectal cancer (CRC) and blood lipids.</p><p><b>RESULTS</b>Among the enrolled subjects, the mean onset age of SPs was 48.87 years (95%CI: 47.22-50.52 years), significantly younger than that of CA (P%0.038). The risk factors both for SPs and CA include an advanced age, a male gender (OR%2.75 [95%CI: 1.50-5.07] for SPs, and OR%2.19 [95%CI: 1.22-3.95] for CA), and a high body mass index (OR%1.18 [95%CI: 1.06-1.30] for SPs and OR%1.20 [95%CI: 1.09-1.32] for CA. Relative to the young individuals (below 45 years of age), the middle-aged individuals (45-60 years of age) had increased risks for SPs and CA by 2.31 [95% CI: 1.46-3.65] folds and 4.10 [95%CI: 2.50-6.72] folds, respectively, and in the elderly (beyond 60 years of age), the risks further increased by 2.77 [95%CI: 1.52-5.04] folds for SPs and by 6.00 [95%CI: 3.26-11.05] folds for CA. Age was more strongly associated with CA than with SPs (OR%2.14 [95%CI: 1.21-3.78], the elderly vs the young, P%0.009).</p><p><b>CONCLUSION</b>SPs and CA have common risk factors, thus the screening strategy for CA may also be applicable to SPs. As the mean onset age of SPs is earlier than 50 years and SPs may rapidly progress to a carcinogenic state, an earlier screening age needs to be considered.</p>

To describe the clinical presentation and treatment strategies for UC in inpatients from Shanghai, China and to improve the therapeutic outcomes for patients with UC.</p><p><b>METHODS</b>Medical records from 247 patients with UC who were admitted to Longhua Hospital Affifiliated to Shanghai University of Traditional Chinese Medicine between January 2008 and June 2013 were analyzed for gender, age, course of the disease, clinical type, extent and severity of the disease, treatment strategies, and therapeutic outcomes.</p><p><b>RESULTS</b>Gender ratios and disease onset of inpatients with UC in the Shanghai area were consistent with other reports in the literature. In contrast to previous studies, most patients exhibited disease of the left colon, over half of the patients had problems of the rectum or sigmoid colon, and most patients had either mild or moderate UC. Comparison of Sutherland Disease Actirity Index scores for patients treated with Chinese medicine (CM) and those treated with integrated CM and Western medicine revealed signifificant reductions in scores for both groups after treatment (P<0.01), with no signifificant difference in therapeutic effects between groups (P=0.938).</p><p><b>CONCLUSIONS</b>Herbal medicine has been widely used in patients with mild to moderate disease and as adjunct therapy in patients with moderate to severe disease. Therefore, the strategy was proposed for the treatment of UC with CM therapy based on 2 steps according to the stage of the disease, even in the clinical setting.</p>

<p><b>OBJECTIVE</b>To detect the expressions of IL-17, IL-23, IL-22 and IL-11 in the intestinal mucosa of patients with ulcerative colitis (UC) and analyze their prognostic values.</p><p><b>METHODS</b>Forty patients with active UC, 15 with UC in remission and 15 healthy subjects were examined for the expressions and distribution of IL-17, IL-23, IL-22, and IL-11 in the colorectal mucosausing immunohistochemistry. We further collected the data from 40 patients with routine therapy and regular follow-up and compared the expressions of those cytokines according to the condition of mucosal healing.</p><p><b>RESULTS</b>The expressions of cytokines in patients with active UC were significantly higher than those in patients with remittent UC and healthy control subjects (IL-17: 0.0727∓0.0037 vs 0.0354∓0.0243 vs 0.0330∓0.0045; IL-23: 0.1407∓0.0068 vs 0.0865∓0.0051 vs 0.0442∓0.0137; IL-22: 0.0522∓0.0045 vs 0.0259∓0.0063 vs 0.0115∓0.0061; IL-11: 0.0479∓0.0022 vs 0.0365∓0.0024 vs 0.0232∓0.0009, P<0.05). The expression levels of IL-17, IL-23, and IL-22 increased significantly with the increase of the disease activity (IL-17: 0.0545∓0.0072 vs 0.0786∓ 0.0051 vs 0.0847∓0.0197; IL-23: 0.1112∓0.0046 vs 0.1480∓0.0089 vs 0.1644∓0.0190; IL-22: 0.0307∓0.0063 vs 0.0548∓ 0.0071 vs 0.0719∓0.0056, P<0.05). In patients with active UC, the expression levels of the 4 cytokines in the intestinal mucosa were positively correlated with the endoscopic activity grade (P<0.05), and IL-17 and IL-22 expression levels were also positively correlated with the histological grade (P<0.05). All the 4 cytokines were positively intercorrelated. The patients with low IL-17 expression (25.00%) showed a significantly lower rate of poor mucosal healing than those with high IL-17 expressions (25% vs 67%, P<0.05).</p><p><b>CONCLUSION</b>The cytokines IL-17, IL-23, IL-22, and IL-11 all participate in the pathogenesis of UC and may serve as indicators for evaluating the inflammatory activity. The expression level of IL-17 can be a valuable indicator for predicting mucosal healing in UC patients after a short-term treatment.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of arsenic trioxide (AsO) on K562 cell proliferation by regulating cell cycle protein D1 and cyclin-dependent kinase inhibitor p27kip1.</p><p><b>METHODS</b>MTT was used to detect the effect of AsOon K562 cell proliferation, so as to screen out the appropriate drug concentration. Furthermore, the K562 cell apoptosis was observed by microscopy. The expression of CyclinD1 and p27kip1 in K562 cells treated with AsOwas analyzed by reverse transcription-polymerase chain reaction(RT-PCR), immunohistochemistry and Western blot.</p><p><b>RESULTS</b>AsOcould inhibit the proliferation of K562 cells in a dose- and time- dependent manner (r= 0.967). And the apoptosis cell number in AsOgroup was significantly higher than that in the control group(P<0.05). AsOcould markedly inhibit the expression of CyclinD1 in K562 cells(P<0.05), but the expression of P27kip1 was not significantly changed after AsOtreatment.</p><p><b>CONCLUSIONS</b>AsOcan induce K562 cell apoptosis and inhibit K562 cell proliferation by regulating the expression of CyclinD1.</p>
