ABSTRACT

Objective:To investigate the clinicopathological features and pathological diagnosis methods of calcifying fibrous tumor (CFT) of the stomach.Methods:The clinicopathological data of 9 patients with gastric CFT in the Second Hospital of Hebei Medical University from August 2015 to May 2020 were retrospectively analyzed, immunohistochemistry was used to detect the immunophenotypic characteristics of gastric CFT, and the relevant literature was reviewed.Results:Among 9 patients with gastric CFT, 1 case was male and 8 cases were female, with a median age of 53 years old (18-63 years old). There were 7 cases occurred in the body of the stomach, while 2 cases in the fundus. All cases were single solid nodule with the cut surface gray-white or gray-red in colour and hard and tough in texture. Maximum diameter of tumor ranged from 0.6 cm to 1.5 cm. Observation under the microscope showed the spindle-shaped tumor cells were sparsely distributed in a large amount of collagenized stroma with scattered lymphocytes and plasma cells infiltration. Calcification or gravel formation was detected in all cases. The tumor cells in 9 cases expressed Vimentin, 3 cases expressed CD34, none of them expressed PDGFRA, SMA, SMMS-1, Desmin, ALK, DOG-1, CD117, S-100, β-catenin, CKpan and calponin; Ki-67 positive index was 1%-3%.Conclusions:Gastric CFT is more common in middle-aged and elderly people, which is characterized by gastric body with smaller volume. The diagnosis of gastric CFT mainly depends on pathological morphology and immunohistochemical examination. It needs to be differentiated from a variety of spindle cell tumors more commonly found in the stomach.

ABSTRACT

Objective@#To explore the intrinsic mechanism of emotional intelligence and trait anger in the association between childhood psychological abuse and aggressive behavior among middle school students,and to provide a theoretical basis for intervention of aggressive behaviors.@*Methods@#By using the multi-stage stratified random sampling method, 2 458 middle school students in Guizhou Province were selected, and group tests were carried out using psychological abuse scale, attack behavior scale,emotional intelligence scale and characteristic anger scale.@*Results@#Agressive behavior, trait anger and emotional intelligence differed significantly by gender(t=2.19,5.12,-2.34,P<0.05), and there were significant differences in aggressive behavior, psychological abuse, emotional intelligence and trait anger among middle school students of different student origins by residence(t=-18.77,-6.04,9.10,-9.94,P<0.05). Childhood psychological abuse (r=0.41), temperamental trait anger (r=0.52) and reactive trait anger (r=0.49) were significantly positively correlated with aggressive behavior(P<0.05). Emotional intelligence was significantly negatively correlated with aggressive behavior (r=-0.33, P<0.05). The test of multiple mediation effects showed that emotional intelligence, temperamental trait anger and reactive trait anger played multiple mediation roles between psychological abuse and aggressive behavior in childhood.@*Conclusion@#Childhood psychological abuse could not only directly affect the aggressive behavior of middle school students, but also further affect the aggressive behavior through emotional intelligence and trait anger. Emotional intelligence and idiosyncratic anger are important internal mechanisms by which childhood psychological abuse affects aggressive behavior.

ABSTRACT

Objective:To explore the risk factors of intensive care unit-acquired weakness (ICU-AW) and the characteristics of Medical Research Council (MRC) score and electromyogram.Methods:A case control study was conducted. Patients with mechanical ventilation ≥ 7 days and MRC score admitted to department of respiratory and critical care medicine of China-Japan Friendship Hospital from September 2018 to January 2020 were enrolled, and they were divided into ICU-AW group (MRC score < 48) and non-ICU-AW group (MRC score ≥ 48) according to MRC score. The general situation, past medical history, related risk factors, MRC score, respiratory support mode, laboratory examination results, electromyogram examination results, ICU-AW related treatment, outcome and length of ICU stay were collected, and the differences between the two groups were compared. The risk factors of ICU-AW were analyzed by binary multivariate Logistic regression, and the characteristics of MRC score and electromyogram were analyzed.Results:A total of 60 patients were enrolled in the analysis, including 17 patients in ICU-AW group and 43 patients in non-ICU-AW group. Univariate analysis showed that there were significant differences in acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, brain natriuretic peptide (BNP), blood urea nitrogen (BUN) on the first day of ICU admission and the ratio of invasive mechanical ventilation between ICU-AW group and non-ICU-AW group [APACHEⅡ score: 21 (18, 25) vs. 18 (15, 22), SOFA score: 7 (5, 12) vs. 5 (3, 8), BNP (ng/L): 364.3 (210.1, 551.2) vs. 160.1 (66.8, 357.8), BUN (mmol/L): 9.9 (6.2, 17.0) vs. 6.0 (4.8, 9.8), invasive mechanical ventilation ratio: 88.2% vs. 46.5%, all P < 0.05]. Binary multivariate Logistic regression analysis showed no independent risk factor for ICU-AW. The average MRC score of 17 ICU-AW patients was 33±11. The limb weakness was symmetrical, and the proximal limb weakness was the main manifestation. Electromyography examination showed that the results of nerve conduction examination in ICU-AW patients mainly revealed that the amplitude of compound muscle action potential (CMAP) and sensory nerve action potentials (SNAP) were decreased, and the conduction velocity was slowed down; needle electromyography showed increased area of motor unit potential (MUP), prolonged time limit and a large number of spontaneous potentials. Prognosis evaluation showed that compared with non-ICU-AW group, patients in ICU-AW group underwent more tracheotomy (70.6% vs. 11.6%), longer length of ICU stay (days: 57±52 vs. 16±8), and more rehabilitation treatment (58.8% vs. 14.0%), and the differences were statistically significant (all P < 0.01). Conclusions:The occurrence of ICU-AW may be related to high APACHEⅡ score and SOFA score, high levels of BNP and BUN on the first day of ICU admission and the proportion of invasive mechanical ventilation, but the above factors are not independent risk factors for ICU-AW. The MRC score of ICU-AW patients was characterized by symmetrical limb weakness, mainly proximal limb weakness; in electromyography examination, the nerve conduction examination results mainly showed that CMAP and SNAP amplitude were decreased, and conduction velocity was slowed down; needle electromyography examination showed increased MUP area, prolonged duration and a large number of spontaneous potentials.

ABSTRACT

OBJECTIVE@#To explore the renal pathology and cytogenetic features in the multiple myeloma (MM) patients with renal impairment.@*METHODS@#The clinical data of newly diagnosed MM patients with renal impairment in our hospital from January 2009 to January 2019 were analyzed retrospectively, and the relationship between FISH results and results of renal pathological exanimation was analyzed statistically by using SPSS 20.0.@*RESULTS@#A total of 20 patients underwent renal biopsy, included 12 males and 8 females. FISH result showed that out of 20 patients, 7 cases presented interstitial nephritis, among which 3 cases were negative for FISH, and in the remaining cases the rate of IgH rearrangement, 1q21 amplification, RB1 deletion, D13S319 deletion, and P53 deletion detection was 42.86%, 28.57%, 28.57%, 28.57% and 14.29% respectively, the detection positive rate was statistically significantly lower as compared with total probe positive rate (P<0.01). There were 6 cases of cast nephropathy, among which IgH rearrangement, the rate of 1q21 amplification, RB1 deletion, D13S319 deletion, and P53 deletion detection was 66.67%, 50%, 66.67%, 50% and 0% respectively. Compared with the total probe positive rate, there was no statistical significance (P>0.05). There were 4 cases of acute tubular necrosis, among which the detection rates of IgH rearrangement, 1q21 amplification, RB1 deletion, D13S319 deletion, and P53 deletion was 100%, 50%, 50%, 25% and 25%, respectively. Compared with the total probe positive rate, there was no statistical significance (P>0.05). There were one case of amyloidosis, and one case of tubular nephropathy with amyloidosis, the detection with 5 probes were all positive. One case of light chain deposition disease was positive for RB1 gene deletion + D13S319 gene deletion.@*CONCLUSION@#FISH in the MM patients with different renal pathological changes is characterized by heterogeneity, which can be used to predict the risk of renal damage and speculate possible renal pathological types to guide prognosis.

ABSTRACT

ABSTRACT Objectives: Our study aimed to investigate the associations of glucose tolerance status with insulin-like growth factor-I (IGF-I) and other clinical laboratory parameters of acromegalic patients before and after the patients underwent transsphenoidal adenomectomy (TSA) by conducting a single-center, retrospective study. Subjects and methods: A total of 218 patients with acromegaly who had undergone TSA as the first treatment were retrospectively analyzed. Serum IGF-I, growth hormone (GH) and glucose levels were measured before and after surgery. Results: The follow-up levels for random GH, GH nadir, and the percentage of the upper limit of normal IGF-I (%ULN IGF-I) were decreased significantly. The percentages of normal (39.0%), early carbohydrate metabolism disorders (33.0%) and diabetes mellitus (28.0%) changed to 70.2%, 16.5% and 13.3%, respectively, after TSA. %ULN IGF-I at baseline was higher in the diabetes mellitus (DM) group than in the normal glucose tolerance group and impaired glucose tolerance (IGT) /impaired fasting glucose (IFG) groups before TSA, and the DM group exhibited a greater reduction in %ULN IGF-I value after surgery. The follow-up %ULN IGF-I value after surgery was significantly lower in the improved group, and Pearson's correlation analysis revealed that the reductions in %ULN IGF-I corresponded with the reductions in glucose level. Conclusion: This study examined the largest reported sample with complete preoperative and follow-up data. The results suggest that the age- and sex-adjusted IGF-I level, which reflects altered glucose metabolism, and the change of it are associated with improved glucose tolerance in acromegalic patients both before and after TSA.

ABSTRACT

Bacterial biofilm refers to a tunicate-like biological group composed of polysaccharide, protein and nucleic acid secreted by bacteria on the surface of the mucous membrane or biological material. The biofilm formation is a major cause of chronic infections. Bacteria could produce some secondary metabolites during the growth and reproduction. Some of them act as signaling molecules allowing bacteria to communicate and regulate many important physiological behaviors at multiple-cell level, such as bioluminescence, biofilm formation, motility and lifestyles. Usually, these signal molecules play an important role in the formation of bacterial biofilm. We review here the effects of related signal molecules of Quorum Sensing, cyclic diguanylate, Two-Component Systems and sRNA on the biofilm formation. Focusing on these regulation mechanism of signal molecules in the process of biofilm formation is necessary for the prevention and treatment of some chronic diseases.

ABSTRACT

To systemically evaluate the benefits and side effects of Shensong Yangxin Capsules( SYC) in the adjuvant treatment of stable angina pectoris( SAP). Chinese and English databases( PubMed,EMbase,the Cochrane Library,CBM,CNKI,VIP,Wan Fang database) were retrieved to collect the randomized controlled trials( RCTs) about therapeutic efficacy of SYC combined with routine drug( trial group) vs routine drug( control group) in the treatment of SAP. The methodological quality of the RCTs was evaluated based on the cochrane risk of bias assessment tool. The data were extracted and Meta-analyzed by Reviewer Manager 5. 3. TSA 0. 9 software was used for trial sequential analysis( TSA) of the total effective rate of symptoms improvement. A total of 15 RCTs with 1 316 participants were included. RESULTS:: of Meta-analysis showed that the total effective rate of angina symptoms improvement( RR = 1. 15,95% CI[1. 09,1. 21],P<0. 001) of trial group were significantly higher than those of control group,with statistical significance,the total effective rate of electrocardiograms( ECG) improvement( RR = 1. 10,95% CI[0. 94,1. 29],P = 0. 25) of trial group were significantly higher than those of control group,but the difference was not statistically significant. After treatment,the improvement of the total time of 24 h general ischemia( SMD =-1. 21,95%CI[-1. 97,-0. 45],P = 0. 002),the ST-segment depression amplitude( SMD =-1. 30,95%CI [-1. 52,-1. 09],P<0. 001),the duration of angina pectoris attack( SMD =-1. 16,95% CI[-1. 36,-0. 95],P< 0. 001),the angina pectoris attack every week( SMD =-0. 80,95%CI[-1. 10,-0. 50],P<0. 001),the onsumption of nitroglycerin every week( SMD=-0. 72,95%CI[-1. 05,-0. 39],P<0. 001) in the trial group were better than that of the control group,and the difference was statistically significant. Besides,the improvement of the blood lipid and high sensitivity C reactive protein( hs-CRP) in the trial group were better than those of the control group after treatment,and the difference was statistically significant( P< 0. 001). Funnel plots and Egger's linear regression showed that there was no publication bias. By sensitivity analysis,it showed that the results of this study were stable and reliable. No obvious adverse drug reactions were observed in all studies. TSA analysis showed that the evidence of Meta-analysis was reliable. SYC combined with routine Western medicine treatment for SAP can improve the total effective rate of angina pectoris,reduce 24 h total ischemia time,ST segment depression amplitude,duration of angina pectoris attack,frequency of angina pectoris attack and nitroglycerin dosage,and also can improve blood lipid and hs-CRP levels.

ABSTRACT

Objective: To investigate the effects and mechanism of osthole on proliferation and apoptosis in a hepatocellular carcinoma cell ( HCC) line Hep G2. Methods: Treated cells with osthole at different concentrations. Cell viability was measured by CCK8 assay and apoptosis was detected by flow cytometry. Western blot was performed for calculating the expression levels of proliferation-related, apoptosis-related proteins and PTEN. After pretreatment with bp V ( HOpic), cell proliferation and apoptosis were measured again. Results: Treatment with osthole ( 100 μmol/L) for 4 and 5 days inhibited cell viability of HCC markedly ( P<0. 05, P<0. 01). Osthole ( 150 μmol/L) decreased cell viability of HCC with a time-dependently manner and also decreased the expressions of Ki67 and PCNA ( P<0. 05, P<0. 01). Meanwhile, treatment with osthole ( 100 μmol/L, 150 μmol/L) induced apoptosis of HCC significantly coupled with increasing Bax and decreasing Bcl-2 ( P<0. 05, P<0. 01). In addition, osthole ( 100 μmol/L, 150 μmol/L) up-regulated the protein level of PTEN ( P<0. 05, P< 0. 01). Furthermore, pretreatment with bp V ( HOpic) ( 1 μmol/L) notably reversed the inhibitory effect on proliferation and promotive effect on apoptosis of osthole ( P<0. 05). Conclusion: Osthole inhibits cell proliferation and induces apoptosis of HCC by up-regulating the protein level of PTEN.

ABSTRACT

To systemically evaluate the efficacy and safety of salvianolate intravenous drip in combination with hydration against contrast-induced nephropathy( CIN),and guide clinical medication. Chinese and English databases( PubMed,EMbase,the Cochrane Library,CBM,VIP,Wan Fang database,CNKI) were retrieved to collect the randomized controlled trials( RCTs) about the efficacy of salvianolate intravenous drip in combination with hydration( trial group) vs routine hydration( control group) in the prevention of contrastinduced nephropathy. The methodological quality of the RCTs was evaluated by using the Cochrane 5. 1. 0 Bias Risks Assessment Tool.The data were extracted and Meta-analysis was conducted by Reviewer Manager 5. 3. Egger's test and non-parametric clipping method were used to evaluate publication bias. A total of 9 RCTs with 2 186 participants were included. RESULTS:: of Meta-analysis showed that the incidence of contrast-induced nephropathy of trial group was significantly higher than that of control group( RR = 0. 46,95% CI[0. 35,0. 59],P<0. 001). Subgroup analysis showed that the incidences of CIN in patients with acute coronary syndrome( ACS) undergoing PCI,in patients with the average age≥65 years,in patients who received mean contrast volume ≥200 m L,in patients with serum creatinine( Scr) ≥ 80 μmol,or in patients who received intraoperative administration of salvianolate or PCI were higher than those in control group,with statistically significant differences( P<0. 05). The experimental group was superior to the control group in improving the indexes of renal function after operation,and the difference was statistically significant( P<0. 05). No study reported the incidence of adverse reactions( ADRs). The funnel plots of the incidence of CIN showed potential publication bias. The results of Egger's linear regression showed that there was certain publication bias. Sensitivity analysis,funnel plot,and " trim and fill" showed that the results of this study were stable and reliable. Salvianolate combined with routine hydration showed definite clinical efficacy in the prevention of contrast-induced nephropathy. However,exact conclusion should be further verified by additional high-quality,multi-centre,and large-scale RCT studies.

ABSTRACT

@#Objective    To investigate the correlation between lung ultrasonography and pulmonary complications after cardiac surgery. Methods    Fifty-two patients after cardiac surgery in our hospital from January to May 2017 were recruited. There were 27 males and 25 females, aged 60.50±10.43 years. Lung ultrasonography was performed by specially trained observers, video data were saved, and lung ultrasound score (LUS) were recorded. The correlation between the LUS and the patients' pulmonary function was evaluated. Results    LUS was 17.80±3.87, which was negatively correlated to the ratio of arterial PO2 to the inspired oxygen fraction (PaO2/FiO2) during examination, without significant difference (r=–0.363, P=0.095), but significantly negatively correlated to PaO2/FiO2 changes 24 hours postoperatively (r=–0.464, P=0.034). Conclusion    The changes of lung ventilation area may occur earlier than the changes of lung function. Bedside LUS is an effective method for clinical monitoring of pulmonary complications.

ABSTRACT

Aim To investigate the effect of pyropheophorbide-a methyl ester-mediated photodynamic therapy (MPPa-PDT) on migration in human breast cancer MCF-7 cells as well as its possible molecular mechanism. Methods MCF-7 cells were randomly divided into control group, MPPa group, light group and MP- Pa-PDT group. Cells were co-cultured with MPPa at different concenlrations(0, 0. 5, 1,2,4 jimol • L"1) and exposed to light of different energy intensities, 0. 9, 1. 8, 2. 7, 3. 6 J/cm2). Cell viability was measured by CCK-8; production of ROS was detected by DCFH-DA staining; cell migration was mesured by Tr- answell migration assay and wound healing assay; the expressions of E-cadherin, PTEN, Akt, p-Akt were measured by Western blot. Results Compared with control group, MPPa group and light group, MPPa- PDT could significantly inhibit cell viability of MCF-7 cells in an energy-dependent manner. DCFH-DA staining suggested ROS in MPPa-PDT group was higher than that in the other three control groups; Transwell assay and wound healing assay showed cell migration in MPPa-PDT group was significantly inhibited; Western blot analysis indicated that the expression of E-eadhcr- in, PIXN in MPPa-PDT group increased, while p-Akt decreased. Conclusions MPPa-PDT inhibits MCF-7 cells' migration, and PTEN/AKT signal pathway may be involved in the process.

ABSTRACT

Objective To assess the value of MRI combined with serum ferritin analysis in measurement of hepatic iron deposition among patients with hepatic alveolar echinococcosis. Methods A total of 96 patients with definitive diagnosis of hepatic alveolar echinococcosis and 30 healthy volunteers were enrolled and underwent routine 1.5T MR scanning, and all laboratory examination data were captured. The liver-to-muscle signal intensity ratio, serum ferritin level and liver functions were analyzed. Results The liver-to-muscle signal intensity ratio was (1.95 ± 0.57) in patients with hepatic alveolar echinococcosis and (2.22 ± 0.28) in healthy volunteers (t = 2.022, P < 0.05), and the liver-to-muscle signal intensity ratio was negatively associated the serum ferritin level in patients with hepatic alveolar echinococcosis (rs = –0.446, P < 0.01). Conclusions Abnormal iron deposition is detected in the liver of patients with hepatic alveolar echinococcosis, and serum ferritin level may be helpful for the identification of abnormal iron deposition in the liver of patients with hepatic alveolar echinococcosis. The liver-to-muscle signal intensity ratio measured by MRI may be a non-invasive approached used to assess the hepatic iron deposition in patients with hepatic alveolar echinococcosis.

ABSTRACT

Objective@#To investigate the role of lectin-like Ox-LDL receptor-1( LOX-1) in the activation and oxidative stress of cultured human umbilical vein endothelial cell(HUVEC) after human cytomegalovirus(HCMV) infection.@*Methods@#HUVEC were divided into four groups: HCMV, Control, Carrageenan, and HCMV+ Carrageenan. After HCMV AD169 infection, the supernatant of the culture was extracted, and cells were lysed. The levels of LOX-1 mRNA, intercellular adhesion molecule-1(ICAM-1) mRNA and vascular cellular adhesion molecule-1(VCAM-1) in HUVEC were measured by real-time PCR. And the content of nitrogen monoxidum(NO) of the supernatant was detected by nitrate reductase method accordingly.@*Results@#24 h after infection, the mRNA expression of LOX-1, ICAM-1 and VCAM-1 in HUVEC of HCMV infected group increased obviously compared to control, and NO quantity increased accordingly. The mRNA expression of LOX-1, ICAM-1 and VCAM-1 and the quantity of NO decreased after adding the LOX-1 inhibitor carrageenan. There was significant difference between groups(P<0.05).@*Conclusions@#HCMV may increase the mRNA expression of ICAM-1 and VCAM-1 and quantity of NO by upregulating the mRNA expresion of LOX-1, which may contribute to the formation of a therosclerosis(AS).

ABSTRACT

Objective@#To understand rural school toilet sanitation conditions in Chongqing during the year of 2015 to 2017.@*Methods@#One primary school and one secondary school from each village were selected from five villages of each district. A total of 265 rural schools from 10 districts of Chongqing including 144 primary and 121 secondary schools were selected. Data was collected through access to information, field observations and onsite interview.@*Results@#The sanitation coverage rate was 78.45%, 92.99%, 100% from 2015 to 2017, respectively. The coverage rate in teaching building was the lowest(43.02%, 51.65% and 57.95% from 2015 to 2017, respectively). Male toilets in secondary schools showed high quality(92.38%, 92.86%, 100.00% for the year of 2015, 2016 and 2017, respectively). However, the quality of female toilets in middle schools was poor(33.33%, 53.06% and 68.00% for the year of 2015, 2016 and 2017, respectively). Daily sanitation management enhanced by year(29.07%, 40.66% and 69.32% during 2015 to 2017). Soap provision in school toilets decreased with year (53.49%, 40.66% and 1.14% for the year of 2015 to 2017, respectively).@*Conclusion@#In the past three years, sanitation condition of rural school toilets in Chongqing has significantly improved. However, toilets in the teaching buildings and dormitories are relatively insufficient. More femalefriendly toilet seats and daily sanitation management require further investment.

ABSTRACT

Objective@#To investigate the epidemiology of iron-deficiency anemia among children aged 0-6 years in plateau area,and to provide a basis for the formulation of prevention and treatment measures for anemia.@*Methods@#A total of 1 512 children aged 0-6 years were randomly selected from 4 counties in plateau area by stratified and cluster sampling. Blood hemoglobin level was tested. Child dietary behaviors were collected from their parents.@*Results@#There were significant differences in the prevalence of children with different age, family location, education level of main dependants, occupation of main dependants and per capita income of family(χ2=12.83,39.48,27.05,44.26,32.45, P<0.05).No significant difference for anemia prevalence in gender and nationality was found. The prevalence of anemia among children aged 0-6 years was 67.0%, and the prevalence was highest among children aged 1 years while decreased with age.Univariate analysis of variance showed that the prevalence anemia was 74.0% in rural children, which was significantly higher than children in urban area 58.6%(χ2=39.48,P<0.05). Low education and income level of caregiver, husbandry in the family, no exclusive breastfeeding under 6 months, and picky eaters positively associated with high prevalence of anemia. The prevalence rate of anemia in 0-6 months old infants fed with mixed feeding and artificial feeding (73.1%, 75.0%) was higher than that of breast feeding (48.9%) (χ2=6.78, P<0.05). Picky eating can lead to a high incidence of anemia in children.@*Conclusion@#Promoting healthy diets and correcting unhealthy dietary pattern through nutrition education to parents might be effective ways to lower the prevalence of anemia among children in plateau areas.

ABSTRACT

BACKGROUND: Non-canonical Wnt pathways play important roles in liver fibrosis. Notum is a newly discovered inhibitor to Wnt proteins. This study was to investigate anti-fibrotic effects of Notum. METHODS: 53 patients with hepatitis B virus (HBV) infection as well as a cell co-culture system of LX-2 and Hep AD38 cells were engaged in this study. Clinical, biological and virological data of each patient were analyzed. Cell viability was detected at different time points. mRNA and protein levels of NFATc1 (Nuclear factor of activated T-cells), Jnk, α-SMA, Col1A1 and TIMP-1 were detected both in LX-2 and liver tissue. Protein levels of NFATc1 and Jnk in liver tissue and their correlations with fibrosis score were analyzed. RESULTS: Hepatitis B virus replication up-regulated Wnt5a induced NFATc1 and Jnk activity in Hep AD38. Notum suppressed NFATc1, Jnk and fibrosis genes expression, reduced cell viability in co-cultured LX-2 cells induced by HBV. Interestingly, Patients with HBV DNA > 5log copies/ml had higher mRNA levels of NFATc1 and fibrosis genes than patients with HBV DNA < 5log copies/ml. Most importantly, protein expressions of NFATc1 and pJnk have positive correlations with liver fibrosis scores in HBV-infected patients. CONCLUSIONS: Our data showed that Notum inhibited HBV-induced liver fibrosis through down-regulating Wnt 5a mediated non-canonical pathways. This study shed light on anti-fibrotic treatment.

ABSTRACT

Purpose To investigate the association of preexisting hypertension at admission with the mortality in patients with systolic heart failure (HF). Method We prospectively investigated the association of preexisting hypertension with the mortality among 1351 patients with HF in Taiwan during an average 12 months (range: 8 months–18 months) follow-up period. A multivariate cox regression analysis for the overall cohort and a subgroup analysis by age were performed. Results After adjustment for all potential risk factors, the associations of preexisting hypertension with cardiovascular mortality were significantly reduced in the overall cohort and those aged less than 65 years (hazard ratios (HR): 0.53, 95% confidence intervals (CI): 0.33–0.84, and 0.28, 95% CI: 0.11–0.67, respectively). However, the associations with all-cause mortality were not significantly different in these two groups (HR: 0.77, 95% CI: 0.54–1.09, and 0.59, 95% CI: 0.32–1.07, respectively). Furthermore, the associations were all nonsignificant in the patients aged older than 65 years. Conclusion Preexisting hypertension have an inverse association with cardiovascular mortality in the Asian patients with systolic HF, particularly for those with younger ages.

ABSTRACT

Abstract Detection of Salmonella is very important to minimize the food safety risk. In this study, the recombinant PagC protein and PagC antibody were prepared and coupled with immunomagnetic beads (IMBs) to capture Salmonella cells from pork and milk samples. And then the SYBR Green qualitative PCR was developed to detect the pathogenic Salmonella. The results showed that the PagC polyclonal antiserum is of good specificity and the capture rate of 0.1 mg IMBs for Salmonella tended to be stable at the range of 70-74% corresponding to the concentrations between 101 and 104 CFU/mL. The method developed demonstrated high specificity for the positive Salmonella samples when compared to non-specific DNA samples, such as Escherichia coli, Staphylococcus aureus, Yersinia enterocolitica, and Yersinia pseudotuberculosis. The limit of detection of this assay was 18 CFU/mL. Detection and quantitative enumeration of Salmonella in samples of pork or milk shows good recoveries of 54.34% and 52.07%. In conclusion, the polyclonal antibody of recombinant PagC protein is effective to capture Salmonella from detected samples. The developed pagC antibody IMBs-qPCR method showed efficiency, sensitivity and specificity for 30 Salmonella detection, enabling detection within 10 h, which is a promising rapid method to detect Salmonella in emergency.
