Abstract
Objective: To understand the auditory cortex resting-state fMRI features for adult post-lingual deafness.Method: The author performed functional connectivity analysis on the study subjects with resting-state fMRI,the region of interest(ROI) of which were based separately on the left and right sides of primary auditory cortex. The data were collected from 8 cases with severe or above sensorineurally post-lingual deafness,compared to a control group of 8 cases with normal hearing. Result: When ROI were based on the left A1 areas of all subjects, the main activating area in the control group was bilateral superior temporal gyrus(STG), while the post-lingual deafness group included the bilateral STG, pre-central gyri, left Transverse temporal gyrus(TTG), post-central gyri and right TTG (P<0.01); when ROI were based on the right A1 areas of all subjects, the main activating area in the control group was the bilateral STG, while the post-lingual deafness group included the bilateral STG, right precentral gyri and post-central gyr i(P<0.01). The data showed statistical significance(P<0.05). Conclusion: After hearing loss functional reorganization takes place in the brains of adults with post-lingual deafness, resulting in possible enhancement of visual sense, tactile sense and other sensory systems in order to compensate information acquisition in daily life. .

Abstract
Objective: To investigate the relationship between gastroesophageal reflux disease (GERD) and obstructive sleep apnea syndrome(OSAS). Methods: Patients diagnosed as GERD and healthy controls without GERD related symptoms or endoscopic esophagitis were enrolled from October 2017 and December 2017. All subjects completed Berlin Questionaire to assess the risk of OSAS. Univariate and multivariate logistic regression models were applied to identify risk factors of OSAS. Results: A total of 177 subjects (97 GERD, 80 controls) were finally selected. Significantly more patients in GERD group had high risk OSAS than those in controls [36.1%(35/97) vs. 17.5%(14/80), P=0.005]. In GERD group, patients with erosive reflux diseases (ERD) had especially higher proportion of high risk OSAS compared with the non-ERD group and the healthy controls [53.3% (24/45) vs. 20.8% (10/48) and 17.5% (14/80), P=0.001]. On univariate analysis, male, aging and reflux esophagitis were identified as risk factors of OSAS (all P<0.01). On multivariate analysis, male (OR=12.156, 95%CI 1.382-106.905, P=0.024), aging (OR=1.132, 95%CI 1.051-1.220, P=0.001), acid regurgitation with reflux esophagitis (OR=5.157, 95%CI 1.327-20.034, P=0.018) were significant risk factors. Conclusions: More GERD patients are combined with high risk OSAS than controls, especially subjects with reflux esophagitis. Male and aging GERD patients with acid regurgitation and reflux esophagitis need further evaluation on OSAS screening.

Abstract
Growing evidence suggests the existence of new antibiotic resistance mechanisms. Recent studies have revealed that quorum-quenching enzymes, such as MacQ, are involved in both antibiotic resistance and cell-cell communication. Furthermore, some small bacterial regulatory RNAs, classified into RNA attenuators and small RNAs, modulate the expression of resistance genes. For example, small RNA sprX, can shape bacterial resistance to glycopeptide antibiotics via specific downregulation of protein SpoVG. Moreover, some bacterial lipocalins capture antibiotics in the extracellular space, contributing to severe multidrug resistance. But this defense mechanism may be influenced by Agr-regulated toxins and liposoluble vitamins. Outer membrane porin proteins and efflux pumps can influence intracellular concentrations of antibiotics. Alterations in target enzymes or antibiotics prevent binding to targets, which act to confer high levels of resistance in respiratory/oral bacteria. As described recently, horizontal gene transfer, including conjugation, transduction and transformation, is common in respiratory/oral microflora. Many conjugative transposons and plasmids discovered to date encode antibiotic resistance proteins and can be transferred from donor bacteria to transient recipient bacteria. New classes of mobile genetic elements are also being identified. For example, nucleic acids that circulate in the bloodstream (circulating nucleic acids) can integrate into the host cell genome by up-regulation of DNA damage and repair pathways. With multidrug resistant bacteria on the rise, new drugs have been developed to combate bacterial antibiotic resistance, such as innate defense regulators, reactive oxygen species and microbial volatile compounds. This review summaries various aspects and mechanisms of antibiotic resistance in the respiratory/oral microbiota. A better understanding of these mechanisms will facilitate minimization of the emergence of antibiotic resistance.

Abstract
Objective: To investigate the effect and related mechanism of salvianolate on myocardial ischemia-reperfusion (I/R) injury in rats. Methods: Thirty-six adult Sprague-Dawley rats were divided into three groups (n=12 each) using random number table method: control group (coronary artery was not ligated) , I/R group (myocardial I/R model was established by ligation and opening of left anterior descending coronary artery) , and salvianolate+I/R group (5 mg/kg of salvianolate was injected through the tail vein at the time of reperfusion) .Triphenyltetrazolium chloride (TTC) stain was utilized to measure the myocardial infarct size. The ELISA method was used to detect myocardial necrotic markers, including cardiac troponin T (TnT) , creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) . Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was used to analyses the levels of apoptosis. The levels of cleaved Caspase-3 protein were analyzed with Western blot.Cold luminescence method was used to detect the ATP level of myocardial tissue. The levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in myocardial tissue were detected by immunofluorescence. Results: (1) The infarct size in control group, I/R group and salvianolate+I/R group were 0, (23.90±5.66) %, and (12.06±5.97) %, respectively (P<0.01 or 0.05) . (2) The TnT level was (0.04±0.03) , (16.96±2.80) , and (6.95±2.31) ng/ml, the CK-MB level was (43.6±23.5) , (1 135.8±180.6) ,and (390.3±121.5) U/L, the LDH level was (119.0±58.6) , (1 838.6±543.8) , and (631.6±228.3) U/L in control group, I/R group and salvianolate+I/R group, all significantly lower in salvianolate+I/R group than in I/R group (all P<0.01) . (3) The rate of TUNEL positive myocardial cells were (1.07±1.16) %, (21.36±4.11) %,and (13.30±3.67) % in control group, I/R group,and salvianolate+I/R group (all P<0.01) . (4) The cleaved Caspase-3 expression was 0.11±0.05, 0.84±0.20,and 0.43±0.09 in control group, I/R group, and salvianolate+I/R group (all P<0.01) . (5) The ATP level of myocardial tissue was (100.0±0.0) %, (34.2±9.2) %,and (62.1±18.0) % respectively in control group, I/R group, and salvianolate+I/R group (all P<0.01) . (6) There was almost no 8-OHdG expression in the myocardial tissue of control group. The expression of 8-OHdG in the myocardial tissue of I/R group was greater than that of the control group. The expression of 8-OHdG in the myocardial tissue of salvianolate+I/R group was less than that of the I/R group. Conclusion: Salvianolate may alleviate myocardial I/R injury of rat through reducing the mitochondrial DNA oxidative damage, protecting mitochondrial function and inhibiting the apoptosis of myocardial cells.

Abstract
The enteric nervous system (ENS) is recognized as a second brain because of its complexity and its largely autonomic control of bowel function. Recent progress in studying the interactions between the ENS and the central nervous system (CNS) has implicated alterations of the gut/brain axis as a possible mechanism in the pathophysiology of autism spectrum disorders (ASDs), Parkinson's disease (PD) and other human CNS disorders, whereas the underlying mechanisms are largely unknown because of the lack of good model systems. Human induced pluripotent stem cells (hiPSCs) have the ability to proliferate indefinitely and differentiate into cells of all three germ layers, thus making iPSCs an ideal source of cells for disease modelling and cell therapy. Here, hiPSCs were induced to differentiate into neural crest stem cells (NCSCs) efficiently. When co-cultured with smooth muscle layers of ganglionic gut tissue, the NCSCs differentiated into different subtypes of mature enteric-like neurons expressing nitric oxide synthase (nNOS), vasoactive intestinal polypeptide (VIP), choline acetyltransferase (ChAT) or calretinin with typical electrophysiological characteristics of functional neurons. Furthermore, when they were transplanted into aneural or aganglionic chick, mouse or human gut tissues in ovo, in vitro or in vivo, hiPSC-derived NCSCs showed extensive migration and neural differentiation capacity, generating neurons and glial cells that expressed phenotypic markers characteristic of the enteric nervous system. Our results indicate that enteric NCSCs derived from hiPSCs supply a powerful tool for studying the pathogenesis of gastrointestinal disorders and brain/gut dysfunction and represent a potentially ideal cell source for enteric neural transplantation treatments.

Abstract
Objective: Characterization and evaluation of the uncertainty of the reference materials of cholesterol in aqueous solution. Methods: The certified reference material GBW09203b was weighed accurately and dissolved into methyl cyclodextrin aqueous solution to prepare six kinds of candidate reference materials of cholesterol according to the concentration. The materials were tested for homogeneity and stability using routine methods and were evaluated the uncertainty derived from the inhomogeneity and instability. The uncertainty due to measurement was derived from the purity of the raw material, the weighing and the density measurement. The certified values and expanded uncertainties were calculated according to the ISO Guide. The expanded uncertainty of the certified value was the combination of standard uncertainty of measurement, inhomogeneity and instability. The coverage factor, k, was determined from the Student's t-distribution corresponding to the calculated effective degrees of freedom and 95% level of confidence. Results: It showed that the six candidate reference materials were homogeneous and were tested to be stable for at least 1 year at -70 ℃ and -20 ℃ using the isochronous stability study. The relative uncertainties due to the inhomogeneity were 0.14%, 0.11%, 0.13%, 0.47%, 0.39% and 0.11%. The relative uncertainty due to the instability was 0.25% at -70 ℃. The uncertainties of measurement were 0.06%, 0.05%, 0.05%, 0.05%, 0.05% and 0.05%.The certified values (reference value ± expanded uncertainty, mmol/L) were as follows: (0.651±0.004), (1.310 ±0.007), (2.574±0.015), (5.210±0.055), (7.710±0.072), (10.242±0.056) mmol/L. Conclusions: Six kinds of certified reference materials for cholesterol in aqueous solution have been prepared, which were homogeneity, stable and reliable. It showed that the uncertainty of measurement was very small compared with the uncertainty due to inhomogeneity and instability.

Abstract
Objective: To analyze the prevalence and control status of diabetes in elderly community residents and related risk factors. Methods: A population-based cross-sectional study was conducted in elderly community residents aged 60-95 years in an urban district of Beijing from September 2009 to June 2010 to collect the general health status of the elderly in the community, the prevalence of diabetes, medication treatment, and laboratory tests were conducted. Results: A sample of 2 102, including 848 males and 1 254 females, were selected through randomized clustering sampling for this study. Most participants had higher educational levels, and the smoking and drinking rates were low among them. The prevalence of diabetes, impaired fasting glucose and impaired glucose tolerance were 24.8%, 2.5% and 30.6%, respectively. The awareness, treatment and control rates of diabetes were 78.5%, 69.3% and 15.9%, respectively. Multivariate logistic regression analysis showed that ORs of obesity, family diabetes history for diabetes were 1.42 (95%CI: 1.14-1.76) and 3.42 (95% CI: 2.70-4.35), respectively compared with control group. Also, obesity and family diabetes history were related risk factors for control status of diabetes. Conclusions: The prevalence of diabetes was relatively high, but the control rate was low in elderly community residents. Obesity, unhealthy lifestyles and family diabetes history were related risk factors.

Abstract
Objective: To investigate the efficiency of FibroScan(FS)and FibroTouch(FT)in liver stiffness measurement(LSM)and fat quantification through a comparative analysis. Methods: The outpatients or hospitalized patients who underwent LSM and fat quantification using FS and FT were enrolled. The differences in success rate and detecting parameters between FS and FT were analyzed, as well as the correlation between FS and FT values. The t-test was used for comparison of normally distributed continuous data between groups, and a one-way analysis of variance or the Kruskal-Wallis test was used for comparison between multiple groups. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. Results: A total of 1621 patients were enrolled. The success rates of FT and FS were 100% and 94.96%, respectively, and the success rate of FS was influenced by sex, age, body mass index, and biochemical markers of liver function. FT has a significantly shorter duration of single detection and a significantly lower number of times of single detection than FS(duration of single detection: 190.21±38.78 s vs 220.89±68.36 s, P < 0.01; number of single detection times: 10.31±1.32 vs 11.81±3.76, P < 0.01), as well as a significantly lower ratio of interquartile range to median of fat quantification in the same patient(5.39%±4.81% vs 17.18%±14.07%, P < 0.01). The LSM and fat quantification of FS were significantly correlated with those of FT(r = 0.645 and 0.620, both Based on the duration and number of times of single detection, success rate, and stability of fat quantification, FT seems to have a better detection efficiency than FS. The detection values of FT and FS can be calculated with regression equations < 0.01). The equations of linear regression were LSM(FT)= 4.435+0.477×LSM(FS); CAP(FT)= 134.71+0.456×CAP(FS). Conclusion: Based on the duration and number of times of single detection, success rate, and stability of fat quantification, FT seems to have a better detection efficiency than FS. The detection values of FT and FS can be calculated with regression equations.

Abstract
Objective: To explore the related factors of anemia during pregnancy and provide scientific evidence for the primary prevention of anemia during pregnancy. Methods: The pregnant women (≤12 pregnant weeks) who received the first pregnancy care in a local medical institution in Hunan province from June 2013 to November 2014 were included in this cohort study, and for them anemia had been excluded by physical examination. Baseline survey and follow up till childbirth were conducted for them. A queue-based nested case-control study (1 ∶ 2) was conducted (380 pregnant women with anemia detected in this study as case group, 760 pregnant women without anemia randomly selected and matched by age, habitual residence during pregnancy as control group. And t test, χ(2) test and logistic regression analysis were conducted to identify related factors of anemia during pregnancy. Results: Multivariate logistic regression analysis indicated that low family annual income level (net income) (OR=2.08, 95%CI: 1.22-3.59), low educational level (OR=2.09, 95%CI: 1.22-3.59), pre-pregnancy perm/hair dye (OR=2.23, 95%CI: 1.63-3.05), early pregnancy vomiting (OR=2.51, 95%CI: 1.56-4.03) were the risk factors for anemia during pregnancy. Intake of vitamin and trace element supplements (OR=0.69, 95%CI: 0.50-0.94), frequent meat, fish, shrimp, egg intakes (OR=0.68, 95%CI: 0.49-0.92), frequent soy milk, milk intakes (OR=0.51, 95%CI: 0.27-0.95) were the protective factors for anemia during pregnancy. Conclusion: A number of factors, such as family annual income level, education level, poisonous and harmful material contact, pregnancy reaction, nutrition, are related to the incidence of anemia during pregnancy, it is necessary to take preventive measures to reduce the incidence of anemia during pregnancy.

Abstract
Objective: To investigate the possible mechanism related to the protective effects of salvianolate in H9c2 cells underwent hypoxia/reoxygenation (H/R)-injury. Methods: H9c2 cells were divided into four groups: control group, salvianolate group (S group), H/R group, and salvianolate+ H/R group(S+ H/R group), in which the H9c2 cells were pretreated with salvianolate before H/R-treatment.Apoptotic cells were detected by Tunel assays and AnnexinⅤ-FITC apoptosis detection kit.The intracellular ATP level, the change of mitochondrial membrane potential and the mitochondrial DNA oxidative damage were also determined in these groups. Results: (1) The apoptosis rate of H/R group(26.36±5.14)% was significantly higher compared to control group(2.71±1.66)%(P=0.000 4), which could be significantly reduced in S+ H/R group(17.28±4.75)%(P=0.012 8 vs. H/R group , P=0.003 9 vs. control group). The ratio of AnnexinⅤ and PI double positive cells in H/R group(28.23±6.73)% was significantly higher compared to control group(3.53±2.83)%(P=0.001 1), which was significantly reduced in S+ H/R group(18.10±4.56)%(P=0.037 2 vs. H/R group, P=0.038 3 vs. control group). (2)The ATP level of H9c2 cells in H/R group(49.05±10.12)% was significantly lower than in control group 100%(P=0.000 5), which was significantly increased in S+ H/R group(68.67±13.32)%(P=0.019 9 vs. H/R group). Confocal microscope showed that red fluorescence was dominant in the control group, red fluorescence was significantly reduced, while green fluorescence was significantly increased in H9c2 cells of H/R group and the fluorescence ratio of red to green in H/R group((37.13±8.47)%) was significantly decreased compared to control group (100%, P=0.000 1), fluorescence ratio of red to green was significantly increased in S+ H/R group((63.77±12.32)% vs. H/R group, P=0.007 3). (3)The mitochondrial DNA oxidative damage in different groups: there was only few 8-hydroxyguanine (8-OHdG) expression, which marked as green, in control group, and 8-OHdG expression was significantly upregulated in H/R group, moreover, the 8-OHdG was co-localized with mitochondria.The expression of 8-OHdG was significantly lower in S+ H/R group compared to H/R group. Conclusion: Salvianolate can reduce mitochondrial DNA oxidative damage, and protect mitochondrial function, thus inhibit myocardial cell apoptosis and eventually reduce the myocardial H/R-injury in H9c2 cells.
