Abstract
Ischemia/reperfusion (I/R) injury is associated with primary percutaneous coronary intervention (PPCI). The current study was performed to compare the effect of tirofiban and recombinant human pro-urokinase (rh-proUK) on the improvement of coronary slow blood after PPCI.Sixty-five ST elevation myocardial infarction (STEMI) patients treated with rh-proUK and an equal number treated with tirofiban after PPCI were employed in the current study. The clinicopathological information regarding the biochemical parameters, thrombolysis in myocardial infarction (TIMI) grade, hemodynamics parameters, thrombus core (TS), sum-STR, left ventricular ejection fraction (LVEF), blood routine parameters, high-sensitivity C-reactive protein (CRP) level, uric acid, hepatorenal function, electrocardiogram (ECG), and echocardiography before and after the interventions were collected. The differences in those parameters between the 2 groups then compared with assess the treatment effect and side effects associated with the both therapies.The results showed that the TIMI level post-intervention (P = .03), the proportion of TIMI myocardial perfusion grade level III (P = .04), the changes in thrombus score (P < .001) in rh-proUK group were significantly higher than those in tirofiban group while the corrected TIMI Frame Count (CTFC) (P = .02), the incidence of slow flow (P = .02), the thrombus score post-intervention (P < .001), the stent length (P = .02), and the number of receiving administration of sodium nitroprusside (P = .01) were significantly lower than those in tirofiban group. Moreover, the levels of CK (P < .001), CK-MB (P = .01), and NT-proBNP 24-hour post-intervention (P < .02) were significantly lower in rh-proUK group than those in tirofiban group and the sum-STR right after the intervention (P < .03) of rh-proUK group was significantly higher than that of tirofiban group. No significant difference was detected between the 2 therapies regarding major adverse cardiac events (MACE).The findings outlined in the current study showed that the improvement effect of rh-proUK on blood flow condition was stronger right after the intervention and the therapy had a similar safety when compared with tirofiban during a 30-day follow-up.

Abstract
Cognitive impairment is a common outcome of ischemic stroke. Our previous work has shown that an experimental stroke in the cortex reduces activity in remote hippocampal layers in rats. This study seeks to uncover the underlying functional connections between these areas by analyzing changes to oscillatory activity, signal power, and communication. We induced an ischemic stroke in the left somatosensory cortex of rats and used linear micro-electrode arrays to simultaneously record from cortex and hippocampus under urethane anesthesia at two weeks and one month after stroke. We found significant increase in signal power, as well as an increase in the number of brain state changes in response to stroke. Our results suggest that the cortex modulates the activity and stability of hippocampal oscillations, which is disrupted following cortical stroke that can lead to cognitive impairment.

Abstract
BACKGROUND Atopic dermatitis (AD) is the most common skin disorder in infancy. However, the diagnosis and definite significance of infantile AD remains a debated issue. OBJECTIVE To analyse the phenotypes of AD in infancy, to establish diagnostic criteria and to estimate the prevalence of this condition in China. METHODS This is a multicentric study, in which 12 locations were chosen from different metropolitan areas of China. Following careful and complete history-taking and skin examination, the definite diagnosis of AD was made and the severity based on the SCORAD index was determined by local experienced dermatologists. Based on the detailed phenotyping, the major and representative clinical features of infantile AD were selected to establish the diagnostic criteria and evaluate their diagnostic efficacy. RESULTS A total of 5967 infants were included in this study. The overall point prevalence of AD was 30.48%. The infantile AD developed as early as at the second month of life, and its incidence peaked in the third month of life at 40.81%. The proportion of mild, moderate and severe AD was 67.40%, 30.57% and 2.03%, respectively. The most commonly seen manifestations in the infantile AD were facial dermatitis (72.07%), xerosis (42.72%) and scalp dermatitis (27.93%). We established the novel diagnostic criteria of infants, which included: (i) onset after 2 weeks of birth; (ii) pruritus and/or irritability and sleeplessness comparable with lesions; and (iii) all two items above with one of the following items can reach a diagnosis of AD: (i) eczematous lesions distributed on cheeks and/or scalp and/or extensor limbs, and (ii) eczematous lesions on any other parts of body accompanied by xerosis. CONCLUSIONS In China, the prevalence of AD in infancy is 30.48% according to clinical diagnosis of dermatologists. The novel Chinese diagnostic criteria for AD in infants show a higher sensitivity and comparable specificity.

Abstract
Objective: To establish automatic liver fibrosis classification models by using traditional machine learning and deep learning methods and preliminaryly evaluate the efficiency. Methods: Gray scale ultrasound images and corresponding elastic images of 354 patients, 247 males and 107 females, mean age (54±12) years undergoing partial hepatectomy in Zhongshan Hospital of Fudan University from November 2014 to January 2016 were enrolled in this study. By using traditional machine learning and deep learning methods, an automatic classification model of liver fibrosis stages (S0 to S4) were established through feature extraction and classification of ultrasound image data sets and the accuracy in different classification categories of each model were calculated, by using liver biopsy as the reference standard. Results: Pathological examination showed 73 cases in pathological stage S0, 40 cases in S1, 49 cases in S2, 41 cases in S3, and 151 cases in S4. The traditional machine classification model based on support vector machine (SVM) classifier and sparse representation classifier and the deep learning classification model based on LeNet-5 neural network, their accuracy rates in the two categories (S0/S1/S2 and S3/S4) were 89.8%, 91.8% and 90.7% respectively; the accuracy rates in the three categories (S0/S1 and S2/S3 and S4) were 75.3%, 79.4% and 82.8% respectively; the accuracy in the three categories (S0 and S1/S2/S3 and S4) were 79.3%, 82.7% and 87.2% respectively. Conclusions: Computer-aided assessment of liver fibrosis progression in patients with chronic hepatitis B has a high accuracy, and can achieve a more detailed classification. This method is expected to be applied in the non-invasive evaluation of liver fibrosis in patients with hepatitis B in clinical work in the future.

Abstract
Stroke is a serious worldwide medical condition that causes neurological function disability. Diffusional kurtosis imaging, which measures the non-Gaussianity of water diffusion, has been demonstrated to be a sensitive biomarker in many neuro-pathologies. This study explores the relationship between neural function recovery and transformation of the ischemic lesion and/or corticospinal tract during the sub-acute phase after stroke by using diffusional kurtosis imaging. We performed a prospective study of function recovery and K metrics of 43 patients with sub-acute ischemic stroke in the middle cerebral artery territory. The effect of rehabilitation treatment was evaluated using both the Fugl-Meyer motor function score and modified Barthel index score at post-treatment compared with admission, and patients were allocated to two groups: good and poor rehabilitation effect (GRE and PRE). Metrics of diffusional kurtosis imaging within ischemic lesion and along the corticospinal tract were acquired, respectively. All three relative axial diffusional kurtoses (rKas) along the corticospinal tract in the GRE group ( n = 21) were significantly larger than those of the PRE group ( n = 22), including rKa in the posterior limb of internal capsule, rKa in the cerebral peduncle, and rKa in the basal part of the pons ( p = 0.014, 0.005, and 0.021, respectively). This multi-parametric magnetic resonance imaging study showed that diffusional kurtosis imaging has the potential to complement existing stroke imaging techniques and revealed its own advantages in elucidating the possible biophysical mechanism of functional restoration underlying ischemic stroke.

Abstract
Abstract
Purpose: To report the patterns of use of hypofractionated radiotherapy (HFRT) (≤16 fractions)in breast cancer and ductal carcinoma in situ (DCIS) patients in Ontario, Canada from 2009 to 2015 and identify factors related to HFRT use.
Methods: A retrospective cohort study of Ontario women diagnosed with breast cancer or DCIS followed by adjuvant breast or chest wall radiation (RT) from 2009 to 2015 was conducted using data from the Institute for Clinical Evaluative Sciences (ICES). Logistic regression models were used to identify factors associated with HFRT use. Physician was included as a random effect. To calculate the potential amount of time that could be saved if all patients were to receive 16 fractions of HFRT, the number of extra RT treatments after the 16th visit was multiplied by the median amount of time spent to treat one patient at our cancer centre (8.76 minutes). This time was found with Sunnybrook Health Sciences Centre data collected from October 2017 to March 2018 (n=523) and represents the amount of time from when a patient enters the RT unit for treatment setup, until the RT beam is turned off.
Results: A total of 42,072 patients were included. Most patients were aged between 50 and 69 years old (56.7%) with stage I or II breast cancer (74.6%) and had breast conserving surgery (BCS) (76.9%). Half previously received chemotherapy and 7.9% were DCIS patients. Use of sequential boost, simultaneous boost, and regional nodal RT was 17.2%, 3.1%, and 31.7% respectively. Institutional variation in HFRT use ranged from 27.5% to 71.6%. HFRT use has increased in all patient populations over the study period. HFRT use was more common in breast cancer and DCIS patients with BCS than in chest wall and nodal RT. Simultaneous boost (OR=0.09), nodal RT (OR=0.08), previous chemotherapy (OR=0.7), stage 0, II, and III breast cancer (OR=0.06 relative to stage I), were correlated with less HFRT use. Older age, later year of diagnosis, sequential boost (OR=0.09), BCS and no surgery (OR=1.2, 1.5 relative to mastectomy) were correlated with higher HFRT use. Institution was significantly correlated to HFRT use. The variance estimate for the physician random effect was 0.33 (p<0.0001). For breast cancer patients with BCS and breast RT specifically, 62,396 extra visits occurred from 2009 to 2015, corresponding to ˜9100 hours of treatment if all patients received HFRT. For the entire patient population, a total of 190,726 extra visits occurred or ˜27,900 hours.
Trends in the use of HFRT (%) from 2009 to 2015 for DCIS and breast cancer patients in Ontario.YearStage I-IV + BCS + Breast RTStage I-IV + BCS + Breast + Nodal RTStage I-IV + Mastectomy + Breast RTStage I-IV + Mastectomy + Breast + Nodal RTDCIS + BCS200962.610.329.09.545.2201062.06.323.76.951.2201162.24.121.34.752.7201263.79.621.711.452.0201365.112.629.315.057.3201469.37.835.415.164.5201573.711.839.217.573.4BCS: breast conserving surgery, RT: radiation treatment
Conclusions: HFRT use in Ontario has increased over time for all patient populations, and reflects the current evidence supporting HFRT in different patient populations, with lower HFRT use seen in chest wall and nodal RT and higher HFRT use in early-stage breast cancer patients with BCS.

Abstract
The aim of the present study was to analyze the effects of Atractylodesin III (codonopsis pilosula) extract that maintains mitochondrial function, up-regulates Bcl-2, inhibits Caspase-3 activity, and ultimately leads to cardiomyocyte apoptosis in a rat model of acute myocardial infarction (AMI). 30 male Sprague-Dawley rats aged 6 months, weighed 150-200 g were randomly divided into sham operation group (SOG), model group (MG) and intervention group (IG). The IG was intragastrically administered with atractylodesin III (30 mg/kg/d) for 7 days. The model group was treated with (30 mg/kg/d) of sterile saline. After 4.5 h, the heart samples from each group were taken, the myocardial infarct size was detected by 2, 3, 5-triphenyltetrazolium chloride (TTC) staining.After ematoxylin & Eosin (HE) staining apoptosis indices were determined by Terminal deoxynucleotidyl transferase TdT-mediated dUTP Nick-End Labeling (TUNEL) method. Apoptosis-related genes and protein including Bcl-2, Bax, and Caspase-3 expression were determined by quantitative real time polymerase chain reaction (qRT-PCR) and western blot respectively. The infarct size and apoptotic index of the MG were significantly higher than SOG. However, infarct size and apoptotic index were reduced in IGcompared to MG (P < 0.05). The levels of Bax and Caspase-3 in the MG were significantly higher, while Bcl-2 and Bcl-2/Bax were lower than those in the SOG. The IG has lower levels of Bax and Caspase-3, higher levels of Bcl-2 and Bcl-2/Bax (P < 0.05) compared to MG. Atractylodesin III decreased apoptosis of myocardial cells in AMI, up-regulated Bcl-2 expression, and inhibited Bax and Caspase-3 activity.

Abstract
BACKGROUND AND AIMS The American Heart Association has outlined seven cardiovascular health (CVH) metrics, including smoking, body mass index, physical activity, dietary pattern, total cholesterol, and fasting plasma glucose, to define and monitor CVH status. Our study was to evaluate the global CVH in adults. METHODS AND RESULTS We searched PubMed, Embase, Cochrane Central Register of Controlled Trials, and reference lists of relevant articles for studies published between 1 January 2010 and 30 June 2018. Included studies should report the proportions of ideal status for the seven CVH metrics and/or provide the prevalence of overall poor (having 0-2 ideal metrics) or ideal (having 5-7 ideal metrics) CVH status in adults. 88 articles were identified: 75 for the prevalence of ideal CVH metrics, 58 for the proportion of overall poor CVH status, and 55 for the proportion of overall ideal CVH status. Smoking had the highest prevalence of ideal status (69.1%) while dietary pattern has the lowest (12.1%). 32.2% and 19.6% of participants had overall poor and ideal CVH, respectively. Females and young adults had better CVH status when compared to males and older adults. There existed regional variations in ideal CVH metrics and overall CVH status. The overall CVH status had improved over study time. CONCLUSION The prevalence of ideal status was low for some metrics, such as dietary pattern, and the overall CVH status was still unsatisfactory. We should continue to measure the CVH status and carry out lifestyle interventions to improve the CVH status in the whole population.

Abstract
Objective: To detect the expression level of YES-associated protein 1 (YAP) in hepatocellular carcinoma (HCC) cell lines and investigate its effects on the proliferation activity and the sensitivity to sorafenib in HCC cells. Methods: Western blot was used to detect the protein expression levels of YAP in SMMC-7721, SK-Hep-1, HepG-2, Huh7 and the normal liver cell line L-O2. YAP specific small interfering RNA (si-YAP) or YAP expression plasmid were transfected in SK-Hep-1 or Huh7 cells, respectively. Cell counting kit-8 (CCK-8) test was used to detect the cell proliferation activity and the cell cycle test was conducted by flow cytometry. SK-Hep-1 and SK-Hep-1 si-YAP cells were subcutaneously injected into the nude mice which were sequentially treated by intragastric administration of sorafenib, and the tumor growth in vivo were observed and compared. Results: The expression of YAP was upregulated in HCC cell lines. Deletion of YAP expression significantly decreased the survival rate of SK-Hep-1 cells [(78.5±0.3)% vs (92.3±0.2)%, P=0.025]. Knockdown of YAP significantly increased the percentage of G(0)/G(1)-phase cells [ (65.4±3.3) % vs (55.7±3.4) %, P=0.039]. On the contrary, upregulation of the YAP expression in Huh7 cells significantly increased the cell survival rate [(81.2±1.3)% vs (62.5±1.1)%, P=0.013] and reduced the percentage of G(0)/G(1)-phase cells [(38.2±3.8)% vs (48.8±2.9)%, P=0.019]. The survival rate of SK-Hep-1 cells treated by si-YAP combined with sorafenib was (31.13±1.79)%, significantly lower than (48.87±0.58) % of SK-Hep-1 cells treated by sorafenib alone (P=0.001), while overexpression of YAP attenuated the inhibitory effect of sorafenib on the survival of Huh7 cells [(69.98±2.94) % vs (53.53±1.93)%, P=0.001]. The tumor weights of SK-Hep-1 group, sorafenib alone group, SK-Hep-1 si-YAP group and SK-Hep-1 si-YAP combined with sorafenib group were (0.96±0.08) g, (0.62±0.08) g, (0.70±0.06) g and (0.27±0.02) g, respectively. The tumor weights of sorafenib alone group and SK-Hep-1 si-YAP group were significantly lower than that of SK-Hep-1 group (P=0.012 and P=0.031, respectively). The tumor weight of SK-Hep-1 si-YAP combined with sorafenib group was significantly lower than that of SK-Hep-1 si-YAP group (P=0.001). Conclusions: The expression of YAP is upregulated in HCC cell lines, which regulates the proliferation, cell cycle, and sensitivity to sorafenib of HCC cells. YAP is a potential molecular target for HCC treatment.

Abstract
Emerging evidence has linked the exosomes to many immunological disorders, including infectious diseases. However, knowledge regarding the role of exosomes in Helicobacter pylori infection is limited. Here, we show that serum exosomes from chronic gastritis patients with H. pylori infection (Hp exosomes) stimulate the expression of the soluble interleukin (IL)-6 receptor (sIL-6R), which is involved in IL-6 trans-signalling in gastric epithelial cells. Interestingly, sIL-6R up-regulates expression of the proinflammatory cytokine IL-1α, and the neutralization of sIL-6R suppresses IL-1α secretion. Thus, Hp exosomes regulate IL-1α expression via sIL-6R-mediated IL-6 trans-signaling. Altogether, this study reveals a novel perspective in which exosomes play a vital role in immunological mechanisms during H. pylori infection.

[PMID: 29432646 DOI: 10.1111/lam.12865] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2017] [Revised: 01/30/2018] [Accepted: 02/04/2018] [Indexed: 11/27/2022]
Abstract
A novel κ-carrageenase gene (CgkB) has been cloned from Pedobacter hainanensis NJ-02 and expressed heterologously in Escherichia coli BL21 (DE3). It consisted of 1935 bp and encoded 644 amino acid residues with a molecular weight of 71·61 kDa. The recombinant enzyme showed maximal activity of 2458 U mg-1 at 40°C and pH 8·0. Additionally, it could retain more than 70% of its maximal activity after being incubated at pH of 5·5-10·0 below 40°C. K+ and a broad range of NaCl can activate the enzyme. The Km and Vmax of CgkB was 2·4 mg ml-1 and 126 mmol mg-1 min-1 . The ESI-MS analysis of hydrolysates indicated that the enzyme can endolytically depolymerize the carrageenan into tetrasaccharides and hexasaccharides. The results indicated that the enzyme with high activity could be a valuable enzyme tool to produce carrageenan oligosaccharides with various activities. SIGNIFICANCE AND IMPACT OF THE STUDY Enzymatic preparation of carrageenan oligosaccharides has drawn increased attention due to their various physiological activities. It is urgent to explore enzyme tools with higher activity and better stability. In this work, a novel κ-carrageenase was identified and characterized from marine bacterium Pedobacter hainanensis NJ-02. The enzyme with high activity could be a valuable tool to produce carrageenan oligosaccharides with various activities.

Abstract
Keratosis follicularis spinulosa decalvans (KFSD) is an X-linked condition characterized by keratotic follicular papules and progressive alopecia, which is caused by mutations in the MBTPS2 gene. We carried out a genetic study on a child who was suspected clinically to have KFSD. Sanger sequencing was performed to detect mutations in the entire coding region of MBTPS2. A novel missense mutation (c.599C>T) was identified in the patient, confirming a diagnosis of KFSD. We reviewed related cases with MBTPS2 mutations for evidence of genotype-phenotype correlations.

Abstract
Warfarin is used as anticoagulant and Compound Danshen prescription (CDP) is able to promote blood circulation. The combination might produce a synergic effect for patients of coronary heart diseases (CHDs) with atrial fibrillation (AF). Whether the combination increases the bleeding risk of warfarin is unclear, so the effects of Compound Danshen dripping pill (CDDP) on the pharmacokinetics (PK) and pharmacodynamics (PD) profiles of warfarin was investigated in patients. The dose and blood concentrations of warfarin, the four indicators of blood coagulation, prothrombin time, activated partial thromboplatin time, thrombin time, fibrinogen, and international normalized ratio value were compared when with and without CDDP treatment. The population PK (PPK) and PPK-PD models were established to assess patient demographics, genetic polymorphisms and CDDP as covariates. And the Seattle Angina Questionnaire was used to evaluate clinical efficacy, and the bleeding risk of combination was analyzed. The results indicated that CDDP had little influence on PK and PD profiles of warfarin in most patients and the combination of CCDP and warfarin would be a promising alternative regime for CHD with AF patients. The study was registered on China Clinical Trial Registry with number ChiCTR-ONRC-13003523.
