ABSTRACT

The purpose of this study was to analyze the value of transrectal shear-wave elastography (SWE) in combination with multivariable tools for predicting adverse pathological features before radical prostatectomy (RP). Preoperative clinicopathological variables, multiparametric magnetic resonance imaging (mp-MRI) manifestations, and the maximum elastic value of the prostate (Emax) on SWE were retrospectively collected. The accuracy of SWE for predicting adverse pathological features was evaluated based on postoperative pathology, and parameters with statistical significance were selected. The diagnostic performance of various models, including preoperative clinicopathological variables (model 1), preoperative clinicopathological variables + mp-MRI (model 2), and preoperative clinicopathological variables + mp-MRI + SWE (model 3), was evaluated with area under the receiver operator characteristic curve (AUC) analysis. Emax was significantly higher in prostate cancer with extracapsular extension (ECE) or seminal vesicle invasion (SVI) with both P < 0.001. The optimal cutoff Emax values for ECE and SVI were 60.45 kPa and 81.55 kPa, respectively. Inclusion of mp-MRI and SWE improved discrimination by clinical models for ECE (model 2 vs model 1, P = 0.031; model 3 vs model 1, P = 0.002; model 3 vs model 2, P = 0.018) and SVI (model 2 vs model 1, P = 0.147; model 3 vs model 1, P = 0.037; model 3 vs model 2, P = 0.134). SWE is valuable for identifying patients at high risk of adverse pathology.

ABSTRACT

Objective To investigate the current status of hepatitis B virus (HBV) infection among hospitalized patients aged 1-18 years, as well as the status of immunity after hepatitis B vaccination. Methods Related data were collected from the patients aged 1-18 years who were hospitalized in Henan Provincial People's Hospital from July 2020 to July 2021, including serological markers for hepatitis B (HBsAg, anti-HBs, HBeAg, anti-HBe, and anti-HBc) and hepatitis B vaccination. The epidemiological situation of HBV infection was analyzed, as well as the immune effect after vaccination. The trend chi-square test was used for trend analysis. Results A total of 10 658 hospitalized patients were collected, among whom there were 6 372 male patients (59.79%) and 4 286 female patients (40.21%). In this population, the patients with positive HBsAg accounted for 0.28% (30/10 658), with a relatively high proportion of 0.68% and 0.62%, respectively, in the 17-and 18-year age groups; the patients with positive anti-HBs accounted for 51.82% (5 523/10 658), with a relatively high proportion of > 63% in the 1-4 years age groups, and there was a reduction in the proportion of patients with positive anti-HBs (fluctuating around 40%) in the 5-18 years age groups. With the increase in age, the positive rate of anti-HBs tended to decrease in both male and female patients (male: χ 2 =8.217, P =0.004; female: χ 2 =10.048, P =0.002). Conclusion Based on the data of hospitalized patients, HBV infection in the population aged 1-18 years in Henan Province has the characteristics of low prevalence rate and high immunity, and the reduction in the proportion of patients with positive anti-HBs at more than five years after vaccination should be taken seriously in this region.

ABSTRACT

The purpose of this study was to explore transrectal ultrasound (TRUS) findings of prostate cancer (PCa) guided by multiparametric magnetic resonance imaging (mpMRI) and to improve the Prostate Imaging Reporting and Data System (PI-RADS) system for avoiding unnecessary mpMRI-guided targeted biopsy (TB). From January 2018 to October 2019, fusion mpMRI and TRUS-guided biopsies were performed in 162 consecutive patients. The study included 188 suspicious lesions on mpMRI in 156 patients, all of whom underwent mpMRI-TRUS fusion imaging-guided TB and 12-core transperineal systematic biopsy (SB). Univariate analyses were performed to investigate the relationship between TRUS features and PCa. Then, logistic regression analysis with generalized estimating equations was performed to determine the independent predictors of PCa and obtain the fitted probability of PCa. The detection rates of PCa based on TB alone, SB alone, and combined SB and TB were 55.9% (105 of 188), 52.6% (82 of 156), and 62.8% (98 of 156), respectively. The significant predictors of PCa on TRUS were hypoechogenicity (odds ratio [OR]: 9.595, P = 0.002), taller-than-wide shape (OR: 3.539, P = 0.022), asymmetric vascular structures (OR: 3.728, P = 0.031), close proximity to capsule (OR: 3.473, P = 0.040), and irregular margins (OR: 3.843, P = 0.041). We propose subgrouping PI-RADS score 3 into categories 3a, 3b, 3c, and 3d based on different numbers of TRUS predictors, as the creation of PI-RADS 3a (no suspicious ultrasound features) could avoid 16.7% of mpMRI-guided TBs. Risk stratification of PCa with mpMRI-TRUS fusion imaging-directed ultrasound features could avoid unnecessary mpMRI-TBs.

ABSTRACT

Objective:To investigate the molecular mechanism for regulation of trophoblast invasion by piR-3127964, which is differentially expressed in placental tissues of preeclamptic and healthy pregnant women.Methods:Placenta samples of healthy (control group, n=12) and preeclamptic pregnant (PE group, n=10) women who delivered by caesarean section and chorionic villi specimens of patients undergoing artificial abortion were collected in the Department of Obstetrics of the First Affiliated Hospital of Chongqing Medical University during November 2020 to August 2021. Total RNA was extracted from placenta samples and sequenced and the expression of piR-3127964 in different tissues was determined by real-time quantitative-polymerase chain reaction (qRT-PCR). The expressions of PIWI proteins including PIWIL-1, PIWIL-2 and PIWIL-3 in different tissues were detected by Western blot. The expressions of two candidate targets, guanine nucleotide-binding protein-like 3-like (GNL3L) mRNA and sialophorin (SPN) mRNA were evaluated by qRT-PCR after exogenous treating HTR-8/SVneo cells with mimics, inhibitor or negative control of piR-3127964, respectively. qRT-PCR was also used to detect the relative expression of GNL3L and SPN at mRNA level in placentas of all women. The interactions between GNL3L/SPN and piR-3127964 were analyzed by double luciferase reporter gene detection. The localization of piR-3127964 and SPN in chorionic villi was detected by fluorescence in situ hybridization and immunofluorescence. Transwell assay was performed to analyze the influence of piR-3127964 on the invasion of HTR-8/SVneo cells and the possible mechanism. Independent sample t-test, analysis of variance, and LSD post test were used for analysis Results:(1) Enrichment pathways of candidate targets predicted by differentially expressed piR-3127964 were associated with cell motility. There were statistically significant differences in piR-3127964 expression in villi, healthy and preeclamptic placentas (2.950±0.853 vs 1.036±0.303 vs 0.254±0.155, F=27.35, P<0.05), and piR-3127964 was predominantly expressed in extravillous cytotrophoblasts (EVTs). (2) The expression of PIWIL-3 protein in placentas of preeclamptic patients was significantly lower than that in healthy placentas and villi (0.810±0.400 vs 3.175±0.429 and 6.843±1.379, F=49.36, P<0.05). (3) Compared with the control group, exogenous piR-3127964 mimics (piR-mimics) and inhibitors (piR-inhibitor) significantly affected the expression of SPN mRNA (0.971±0.045 vs 0.732±0.010, F=6.50; 1.076±0.073 vs 1.293±0.092, F=7.58; both P<0.05), while the expression of GNL3L mRNA had no significant correlation with piR-3127964 level. (4) The luciferase activity of wild-type SPN (SPN-WT) plasmids was significantly affected by piR-mimics (1.010±0.049 vs 0.645±0.047, t=9.34, P<0.05) and piR-inhibitor (1.035±0.058 vs 1.397±0.015, t=-10.60, P<0.05). (5) SPN mRNA was significantly upregulated in placentas of preeclamptic patients than in healthy placentas (2.097±0.239 vs 1.305±0.290, t=-4.22, P<0.05), but no significant difference in the expression of GNL3L mRNA was observed. Immunofluorescence experiment showed that SPN was expressed in EVTs. (6) The invasive potential of HTR8/SVneo cells treated with piR-inhibitor was significantly inhibited, but this effect could be reversed by SPN knockdown (160.714±53.860 vs 371.667±103.061 and 344.333±120.267, F=9.76, both P<0.05). Conclusions:piR-3127964 expression is abnormally downregulated in placentas of preeclamptic patients, resulting in inhibition of trophoblasts invasion through upregulation of SPN expression, which may be related to the pathogenesis of preeclampsia.

ABSTRACT

Purpose@#This study investigated the value of synchronous tele-ultrasonography (TUS) for naive operators in thyroid ultrasonography (US) examinations. @*Methods@#Ninety-seven patients were included in this prospective, parallel-controlled trial. Thyroid scanning and diagnosis were completed by resident A independently, resident B with guidance from a US expert through synchronous TUS, and an on-site US expert. The on-site expert’s findings constituted the reference standard. Two other off-site US experts analyzed all data in a blind manner. Inter-operator consistency between the two residents and the on-site US expert for thyroid size measurements, nodule measurements, nodule features, American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) categories, and image quality was compared. Two questionnaires were completed to evaluate the clinical benefit. @*Results@#Resident B detected more nodules consistent with the on-site expert than resident A did (89.4% vs. 56.5%, P0.75), while resident A achieved lower consistency in ACR TI-RADS categories, composition, echogenicity, margin, echogenic foci, and vascularity (all ICCs 0.40-0.75). Residents A and B had excellent consistency in target nodule measurements (all ICCs >0.75). Resident B achieved better performance than resident A for gray values, time gain compensation, depth, color Doppler adjustment, and the visibility of key information (all P<0.05). Furthermore, 61.9% (60/97) of patients accepted synchronous TUS, and 59.8% (58/97) patients were willing to pay for it. @*Conclusion@#Synchronous TUS can help inexperienced residents achieve comparable thyroid diagnostic capability to a US expert.

ABSTRACT

Knee joint distraction is a new technology for the treatment of knee osteoarthritis in recent years. It could reduce knee pain and improve knee function, which is inseparable from the role of cartilage repair. The mechanism and influencing factors of knee joint distraction in repairing cartilage are the focus of current research. In this paper, the author reviewed literature and found that knee joint distraction could reduce knee joint load and provide a appropriate mechanical environment for cartilage repair, and it is resulting hydrostatic pressure fluctuation in the knee joint not only helps cartilage to absorb nutrients, but also promotes cartilage formation genes and inhibits cartilage matrix degrading enzyme gene expression. In addition, knee joint distraction creates conditions for synovial mesenchymal stem cells to be collected to cartilage injury, and improves ability of synovial mesenchymal stem cells to proliferate and differentiate into a chondrogenic lineage. Knee joint distraction could reduce inflammatory reaction and cartilage injury of knee joint by reducing content of inflammatory factors and inhibiting expression of inflammatory genes. At present, it is known that the factors affect repair of cartilage by knee joint distraction include, increasing weight-bearing activity and height and time of distraction is helpful for cartilage repair, male patients and patients with higher severity of knee osteoarthritis have better cartilage repair effect after knee joint distraction.The better efficacy of cartilage repair on the first year after knee joint distraction predicts a higher long-term survival rate of knee joint distraction with knee preservation. However, the research on the above hot spots is only at the initial stage and further exploration is still needed, in order to better guide clinical application of knee joint distraction.

ABSTRACT

Objective:To investigate the clinical characteristics of patients with aspergillus spondylitis, and to provide reference for timely diagnosis and treatment.Methods:The clinical manifestations, imaging performance, laboratory examination results, diagnosis and treatment outcomes of six patients with confirmed aspergillus spondylitis in Department of Infectious Diseases, Henan Provincial People′s Hospital during April 30, 2015 and May 1, 2020 were retrospectively analyzed.Results:The main manifestations of six patients were fever and neck pain or low back pain. The time from the onset of clinical manifestations to diagnosis was more than two months to 14 months. Spine magnetic resonance imaging (MRI) showed long T1 and T2 signals on vertebral body, high pressure lipid signal, obvious enhanced scan enhancement, and paravertebral abscess formation might be presented. Among the six patients, C-reactive protein increased in four patients, erythrocyte sedimentation rate increased in five patients, β-D-glucan test (G test) increased in three patients, galactomannan antigen test (GM test) increased in four patients. Six patients with aspergillus spondylitis were all confirmed by biopsy of diseased tissue for fungal smear, tissue culture or metagenomics next generation sequencing. After treatment with voriconazole or itraconazole, five patients recovered and one patient was still under treatment.Conclusions:The clinical manifestations and imaging examination of patients with aspergillus spondylitis are nonspecific. Peripheral blood G test and GM test need to be combined for diagnosis. The diagnosis depends on tissue puncture pathology examination, and the metagenomics next generation sequencing is needed if necessary.

ABSTRACT

Objective:To evaluate the short-term prognostic value of model for end-stage liver disease (MELD) combined with high density lipoprotein-cholesterol (HDL-C) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:From December 2015 to December 2018, 182 patients with HBV-ACLF who were treated in Henan Provincial People′s Hospital were included. Prognosis and clinical data including HDL-C, total bilirubin, international standardized ratio (INR), creatinine of patients within 24 hours after admission were collected and analyzed retrospectively.The values of MELD were calculated. The binary logistic regression analysis was used to analyze the independent risk factors affecting 90-day mortality in HBV-ACLF patients.The receiver operator characteristic curve (ROC) and MedCalc 15.2 software were used to assess the predictive value of MELD, HDL-C and MELD-HDL-C model for prognosis. Kaplan-Meier survival curve was performed to analyze the prognosis of patients in different groups.Results:Sixty patients were divided into the death group and 122 patients were divided into the survival group according to the prognosis during hospitalization and 90 days after discharge. The MELD score of patients in the survival group was 21(19, 24), which was significantly lower than that in the death group (29(25, 34)), and the HDL-C value of patients in the survival group was significantly higher than that in the death group (0.3 (0.1, 0.6) mmol/L vs 0.2(0.1, 0.5) mmol/L). The differences were both statistically significant ( Z=-6.290 and -4.087, respectively, both P<0.01). Multivariate logistic regression analysis showed that MELD score and HDL-C value were the independent risk factors for 90-day mortality in patients with HBV-ACLF(odds ratio ( OR)=1.432, 95% confidence interval ( CI)1.271-1.613; OR=0.584, 95% CI 0.487-0.700, respectively; both P<0.01). Areas under the ROC of MELD, HDL-C and MELD-HDL-C scoring models were 0.775, 0.782 and 0.878, respectively. MELD-HDL-C scoring model was superior to both MELD and HDL-C , and the differences were both statistically significant ( Z=3.944 and 3.104, respectively, both P<0.01). When the MELD-HDL-C Youden′s index was set at 0.72, the optimal threshold was 24.69. Patients with MELD-HDL-C score≥24.69 had lower survival rate than patients with MELD-HDL-C score<24.69, and the difference was statistically significant ( χ2=142.900, P<0.01). Conclusion:MELD, HDL-C and MELD-HDL-C scoring systems could predict the short-term prognosis in patients with HBV-ACLF, and the predictive value of MELD-HDL-C has the superiority.

ABSTRACT

PURPOSE@#This meta-analysis compared the clinical outcome of three-dimensional (3D) printing combined with open reduction and internal fixation (ORIF) to traditional ORIF in the treatment of acetabular fractures.@*METHODS@#We searched the Cochrane Library, PubMed, Embase, VIP database, CNKI, and Wanfang database with keywords "acetabular fracture", "3D printing", "three-dimensional printing", "open reduction and internal fixation", "Acetabulum", "Acetabula" from January 2000 to March 2020. Two reviewers independently selected articles, extracted data, assessed the quality evidence and risk bias of included trials using the Cochrane Collaboration' s tools and/or Newcastle-Ottawa scale. When the two analysts had different opinions, they would ask the third analyst for opinion. Randomized controlled trials or retrospective comparative studies of 3D printing combined with ORIF (3D printing group) versus traditional ORIF (conventional group) in the treatment of acetabular fractures were selected. The data of operation time, intraoperative blood loss, intraoperative fluoroscopy times, incidence of complications, excellent and good rate of Matta score for reduction, and excellent and good rate of hip function score were extracted. Stata14.0 statistical software was used for data analysis.@*RESULTS@#Altogether 9 articles were selected, including 5 randomized controlled trials and 4 retrospective studies. A total of 467 patients were analyzed, 250 in the conventional group, and 217 in the 3D printing group. The operation time in the 3D printing group was less than that in the conventional group and the difference was statistically significant (standardized mean difference (SMD) = -1.19, 95% CI: -1.55 to -0.82, p  0.05). There was no significant difference in the excellent and good rate of hip function score at the end of postoperative follow-up between the two groups (OR = 0.84, 95% CI: 0.46-1.56, p > 0.05), but the follow-up time varies from 6 months to 40 months.@*CONCLUSION@#Compared with traditional ORIF, 3D printing combined with ORIF has certain advantages in terms that 3D printing not only helps surgeons to understand acetabular fractures more intuitively, but also effectively reduces operation time, intraoperative blood loss, intraoperative fluoroscopy times, and postoperative complications. However, there were no significant differences in the excellent and good rate of Matta score for reduction and the excellent and good rate of hip function score at the end of follow-up.

ABSTRACT

Objective: To investigate the effects of femoral approach versus radial approach on the incidence of contrast-induced acute kidney injury (CI-AKI) in patients with coronary heart disease, who received twice contrast agents within a short interval. Methods: A total of 322 patients with coronary heart disease, who admitted to the General Hospital of Northern Theater Command from January 2010 to January 2015, were included in this retrospective analysis. All patients exposed to contrast agents twice within 30 days. The patients were divided into two groups according to the approach of interventional operation: radial artery group (n=235) and femoral artery group (n=87). Serum creatinine (SCr) values were detected at 48 and 72 hours post procedure. Endpoint events were CI-AKI, which was defined as SCr increased>0.5 mg/dl (44.2 μmol/L) or relative ratio ((postoperative SCr-preoperative SCr)/preoperative SCr×100%>25%) within 72 hours after contrast agent use after excluding other causes. Clinical characteristics and the incidence of CI-AKI were compared between the two groups, multivariate logistic regression analysis was used to detect the risk factors of postoperative CI-AKI in these patients. Results: The proportion of smoking, PCI history, STEMI patients and levels of fibrinogen, fasting blood glucose, troponin T was significantly higher in femoral artery group than in radial artery group (all P<0.05). The interval between two procedure sessions was significantly longer in the femoral artery group than in the radial artery group (P=0.001). The incidence of CI-AKI tended to be higher in femoral artery group than in radial artery group after the first operation (18.6% (16/87) vs. 11.9% (28/235), P=0.133). CI-AKI incidence after the second operation was similar between the two groups (P>0.05). Multivariate logistic regression analysis showed that interventional approach was not an independent risk factor for postoperative CI-AKI in patients with coronary heart disease undergoing interventional procedures twice within 30 days (P>0.05);STEMI (OR=2.854, 95%CI 1.100-7.404, P=0.031) and diuretics use (OR=4.002, 95%CI 1.470-10.893, P=0.007) were independent risk factors for CI-AKI after the first operation. Conclusion: There is no correlation between the risk of CI-AKI and interventional approaches in patients with coronary heart disease who undergo interventional surgery twice within 30 days.

ABSTRACT

OBJECTIVES: This study investigates the current state of consuming breakfast among elementary school students residing in Malang, East Java, Indonesia, and to identify factors that influence breakfast behavior.METHODS: The research model was set up as per the health belief model, and slightly modified by adding the subjective normative factors of the theory of planned behavior. The survey was conducted from July 17 to August 15, 2017 using a questionnaire, after receiving the permission PNU IRB (2017_60_HR).RESULTS: The subjects were 77 boys (49.4%) and 79 girls (50.6%) suffering from malnutrition with anemia (21.2%) and stunting ratio of Height for Age Z Score (HAZ) (11.5%). Furthermore, moderate weakness (14.8%) and overweight and obesity (12.3%) by Body Mass Index for Age Z Score (BMIZ) were coexistent. According to the results obtained for breakfast, 21.8% did not eat breakfast before school, with 18.8% of the reasons for skipping breakfast being attributed to lack of food. Even for subjects partaking breakfast, only about 10% had a good balanced diet. The average score of behavioral intention on eating breakfast was 2.60 ± 0.58. The perceived sensitivity, perceived severity, perceived benefits, and self-efficacy of the health belief model correlated with breakfast behavior. Of these, self-efficacy (β=0.447, R²=0.200) and perceived sensitivity (β=0.373, R²=0.139) had the greatest effect on breakfast behavior. Mother was the largest impact person among children.CONCLUSIONS: In order to increase the level of breakfast behavior intention among children surveyed in Indonesia, we determined the effectiveness by focus on education which helps the children recognize to be more likely to get sick when they don't have breakfast, and increase their confidence in ability to have breakfast on their own. We believe there is a necessity to seek ways to provide indirect intervention through mothers, as well as impart direct nutrition education to children.

ABSTRACT

@#Objective    To compare the efficacy of percutaneous closure guided by transthoracic echocardiography or angiography in the treatment of patent ductus arteriosus (PDA). Methods    Literature databases such as CNKI, VIP, Wanfang Database, PubMed, Cochrane Library were searched for collecting published literatures on percutaneous closure for PDA guided by transthoracic echocardiography and angiography, retrieval time limit was up to April 2019. Two evaluators independently screened the literature, extracted the data and evaluated the quality according to inclusion and exclusion criteria. The collected data were analyzed by RevMan 5.3 software. Results    Eight studies were included finally, with a total sample size of 681 cases. Meta-analysis showed that there was no statistical difference in the operative success rate between the echocardiography group and the angiography group (RR=0.99, 95%CI 0.97- 1.01, P=0.40). Postoperative complications were less in the echocardiography group than those in the angiography group (RR=0.26, 95%CI 0.11-0.59, P=0.001).The operation time (P<0.000 01), amount of intraoperative radiation (P< 0.000 01), exposure time (P<0.000 01), hospitalization days (P<0.000 01) and hospitalization costs (P<0.000 01) in the echocardiography group were less or shorter than those in the angiography group, and the difference was statistically different. Conclusion    Compared with angiography-guided, transthoracic echocardiography-guided percutaneous closure for PDA is a safe and effective method with less trauma, lower cost, and can replace angiography as one of the guiding methods for PDA.

ABSTRACT

Purpose@#The purpose of this study was to examine the awareness of alcohol use during pregnancy and factors influencing the intention to abstain from alcohol during pregnancy by drinking levels. @*Methods@#Utilizing a comparative descriptive design, a total of 359 female college students were recruited. Measurements were Theory of Planned Behavior (TPB) variables related awareness of alcohol use during pregnancy, Korean Version of the Alcohol Use Disorders Identification Test, knowledge about alcohol use during pregnancy, and socio-demographic factors. Main variables were compared by drinking levels. The factors influencing the intention to abstain from alcohol during pregnancy were identified using hierarchical regression analysis. @*Results@#Non-problematic alcohol behavior group (n=185) had higher the intention to abstain from alcohol during pregnancy than problematic alcohol behavior group (n=174) (t=3.13, p=.002). The significant TPB variables influencing the intention to abstain from alcohol during pregnancy were that attitudes (β =−.44, p<.001), subjective norms (β =.14, p=.026), and perceived behavior control (β =.19, p=.002) in non-problematic alcohol behavior group, whereas the corresponding variables in the problematic alcohol behavior group were attitudes (β =−.51, p<.001) and subjective norms (β =.21, p=.006). @*Conclusion@#It is necessary to increase the intention to abstain from alcohol during pregnancy for the female college students having problematic alcohol behavior. The following strategies are recommended for them; decreasing acceptable attitudes toward alcohol use during pregnancy and reinforcing the influence of social pressure toward to abstain from alcohol during pregnancy.

ABSTRACT

Objective:To observe the clinical efficacy and safety of transcranial direct current stimulation (tDCS) on post-stroke depression (PSD) with Broca's aphasia. Methods:From January to December, 2018, 60 patients with PSD and Broca's aphasia were randomly divided into control group (n = 30) and trial group (n = 30). Both groups accepted routine medicine and rehabilitation. The trial group accepted tDCS, anode over left dorsal lateral prefrontal cortex, while the control group accepted sham stimulation. They were assessed with Stroke Aphasic Depression Questionnaire Hospital Version (SADQ-H) and Aphasic Depression Rating Scale (ADRS) before treatment and one, two and three weeks after treatment. They were also assessed with modified Barthel Index (MBI) before and three weeks after treatment. The adverse effects were investigated with questionnaire as the patients finished treatment or withdrew. Results:There were three patients withdrawing in the control group, and two in the trial group. The scores of SADQ-H and ADRS decreased with time in both groups (Ftime > 100.643, P < 0.001), and the score of SADQ-H was lower in the trial group than in the control group (Fgroup = 6.891, P = 0.011), but no significant difference was found between two groups in the scores of ADRS (Fgroup = 2.925, P = 0.093). There was significance of interaction between group and time (F > 13.642, P < 0.001). The difference of MBI was more in the trial group than in the control group (t = 7.016, P < 0.001). There was no significant difference in the incidence of adverse effects between the two groups (P = 0.5). Conclusion:tDCS is effective on PSD in patients with Broca's aphasia, without obvious adverse effects.

ABSTRACT

Objective@#To observe ascitic interleukin-7 expression level in cirrhotic patients complicated with spontaneous bacterial peritonitis, and to detect the effect of recombinant human IL-7 on CD4+ and CD8+T lymphocyte function.@*Methods@#A total of 84 patients with liver cirrhosis who were hospitalized from August 2017 to April 2018 were selected. Among them, 51 cases were complicated with cirrhosis and untainted ascites, and 33 cases were cirrhosis complicated with spontaneous bacterial peritonitis. Peripheral blood and ascites were collected routinely. The levels of IL-7 in peripheral blood and ascites were measured by enzyme-linked immunosorbent assay. CD4+T cells and CD8+T cells were purified from ascites, and were stimulated with recombinant IL-7. Cellular proliferation, key transcription factors for mRNA, and cytokines production by CD4+T cells in response to IL-7 stimulation was measured. mRNA expression corresponding to perforin, granzyme B, and granulysin as well as cytokines production by CD8+T cells was also measured in response to IL-7 stimulation. Cytolytic and non-cytolytic activity of CD8+T cells in response to IL-7 stimulation was also investigated in both direct and indirect contact co-culture system. Measurement data of the normal distribution were compared between the two groups by Student’s t-test and the data before and after stimulation were compared by paired t-test. Measurements that did not conform to normal distribution were compared between the two groups using Mann-Whitney U test, and data before and after stimulation were compared using Wilcoxon paired test.@*Results@#There was no significant statistical difference in serum IL-7 levels between the two groups [(5 001 ± 1 458) pg/ml vs. (4 768 ± 1 128) pg/ml, P = 0.41]. The level of ascitic IL-7 in cirrhotic patients complicated with SBP was significantly lower than cirrhosis patients with untainted ascites [(966.4 + 155.8) pg/ml vs. (792.1 + 126.4) pg/ml, P < 0.01]. Recombinant IL-7 stimulation promoted the proliferation of CD4+ and CD8+T cells from ascites in patients with liver cirrhosis complicated by SBP. T-bet mRNA relative expression and IFN-γ secretion in CD4+T cells was also elevated in response to IL-7 stimulation in vitro. Moreover, IL-7 stimulation also increased the mRNA expressions of perforin, granzyme B, and granulysin as well as productions of IFN-γ and TNF-α by CD8+T cells. Recombinant IL-7 stimulation elevated cytolytic and non-cytolytic activity of CD8+T cells from ascites in patients with liver cirrohosis complicated by SBP, which manifested as increased target cell death and IFN-γ production in both direct and indirect contact co-culture system.@*Conclusion@#Ascitic IL-7 promotes T lymphocyte function in patients with liver cirrhosis complicated with SBP.

ABSTRACT

ObjectiveTo investigate the clinical effect and safety of sofosbuvir (SOF)-ledipasvir (LDV) in the treatment of patients with HCV genotype 6a chronic hepatitis C (CHC). MethodsA total of 63 patients with HCV genotype 6a CHC who visited Department of Infectious Diseases, Henan Provincial People’s Hospital and Nanfang Hospital, from October 2014 to December 2016 were enrolled in this prospective observational study. They were divided into SOF-LDV group (treated with SOF-LDV for 12 weeks) and PR group (treated with pegylated interferon combined with ribavirin for 24 weeks). HCV RNA was measured during treatment and follow-up, and virologic response was evaluated. The chi-square test was used for comparison of categorical data between two groups, and the Mann-Whitney U test was used for comparison of continuous data between two groups. ResultsThere were no significant differences between the PR group and the SOF-LDV group in rapid virologic response rate (85.3% vs 100%, P>0.05) and virologic response rate at the end of treatment (94.1% vs 100%, P>005). The SOF-LDV group had a significantly higher sustained virologic response rate than the PR group (96.4% vs 73.5%, χ2=438, P=0.036). The PR group had a significantly higher incidence rate of adverse events than the SOF-LDV group(χ2=754,P=0006). During follow-up, one patient with liver cirrhosis in the SOF-LDV group developed small hepatocellular carcinoma, while no patient in the PR group developed liver cancer at the end of follow-up. ConclusionSOF-LDV for 12 weeks is safe and effective in the treatment of HCV genotype 6a CHC, but liver cancer should be closely monitored in patients with liver cirrhosis.

ABSTRACT

Angiotensin (Ang)-(1-7) is an important biologically-active peptide of the renin-angiotensin system. This study was designed to determine whether inhibition of Ang-(1-7) in the hypothalamic paraventricular nucleus (PVN) attenuates sympathetic activity and elevates blood pressure by modulating pro-inflammatory cytokines (PICs) and oxidative stress in the PVN in salt-induced hypertension. Rats were fed either a high-salt (8% NaCl) or a normal salt diet (0.3% NaCl) for 10 weeks, followed by bilateral microinjections of the Ang-(1-7) antagonist A-779 or vehicle into the PVN. We found that the mean arterial pressure (MAP), renal sympathetic nerve activity (RSNA), and plasma norepinephrine (NE) were significantly increased in salt-induced hypertensive rats. The high-salt diet also resulted in higher levels of the PICs interleukin-6, interleukin-1beta, tumor necrosis factor alpha, and monocyte chemotactic protein-1, as well as higher gp91 expression and superoxide production in the PVN. Microinjection of A-779 (3 nmol/50 nL) into the bilateral PVN of hypertensive rats not only attenuated MAP, RSNA, and NE, but also decreased the PICs and oxidative stress in the PVN. These results suggest that the increased MAP and sympathetic activity in salt-induced hypertension can be suppressed by blockade of endogenous Ang-(1-7) in the PVN, through modulation of PICs and oxidative stress.

ABSTRACT

Metformin (MET), an antidiabetic agent, also has antioxidative effects in metabolic-related hypertension. This study was designed to determine whether MET has anti-hypertensive effects in salt-sensitive hypertensive rats by inhibiting oxidative stress in the hypothalamic paraventricular nucleus (PVN). Salt-sensitive rats received a high-salt (HS) diet to induce hypertension, or a normal-salt (NS) diet as control. At the same time, they received intracerebroventricular (ICV) infusion of MET or vehicle for 6 weeks. We found that HS rats had higher oxidative stress levels and mean arterial pressure (MAP) than NS rats. ICV infusion of MET attenuated MAP and reduced plasma norepinephrine levels in HS rats. It also decreased reactive oxygen species and the expression of subunits of NAD(P)H oxidase, improved the superoxide dismutase activity, reduced components of the renin-angiotensin system, and altered neurotransmitters in the PVN. Our findings suggest that central MET administration lowers MAP in salt-sensitive hypertension via attenuating oxidative stress, inhibiting the renin-angiotensin system, and restoring the balance between excitatory and inhibitory neurotransmitters in the PVN.

ABSTRACT

@#Objective    To systematically evaluate the clinical value of miRNA-1 in the diagnosis of acute myocardial infarction (AMI) patients. Methods    We searched PubMed, EMbase, Cochrane Library, CNKI, Wangfang, VIP, etc databases to identify literature about miRNA-1 in the diagnosis of AMI. Quality of the included literature was assessed by (quality assessment for diagnostic accuracy studies-2, QUADAS-2). The indices of pooled sensitivity (Sen), specificity (Spe), positivity likelihood ratio (PLR), negative likelihood ratio (NLR), diagnosis odds ratio (DOR), and the area under the summary receiver operating characteristic (SROC) curve were pooled using MetaDisc 1.4 software. Results    A total of 12 articles were included. According to the different populations of miRNA-1 to be tested, subgroup analysis of healthy people (7 articles) and non-AMI disease groups (5 articles) was conducted. The results showed that AMI compared with healthy people, the pooled Sen was 0.78 with 95%CI 0.73 to 0.82, Spe was 0.88 with 95%CI 0.83 to 0.91 of miRNA-1 in the diagnosis of AMI. AUC of SROC curve was 0.911 2. Comparison of AMI and non-AMI patients, the pooled Sen was 0.59 with 95%CI 0.54 to 0.64, Spe was 0.74 with 95%CI 0.68 to 0.79 of miRNA-1 in the diagnosis of AMI. AUC of SROC curve was 0.743 2. Conclusion    MiRNA-1 has a certain value in the diagnosis of AMI. It has an advantage in identifying AMI and patients with other systemic diseases, and can be combined with other biomarkers to  diagnose AMI.
