ABSTRACT
Objective lo analyze the difference of peri-coronary tat attenuation index(pr Al)on different grades of hypertension(HT),and to explore the value of pFAI in evaluating the risk of HT patients.Methods Retrospective data on hospitalized patients who underwent coronary computed tomography angiography(CCTA)examination for chest pain were collected.A total of 415 clini-cally confirmed HT patients were selected as observation group(including 132 patients in grade 1 HT group,137 patients in grade 2 HT group,146 patients in grade 3 HT group),and 187 non-hypertension patients during the same period as control group.The differ-ence of fat attenuation index(FAI)in three main coronary arteries[left anterior descending artery(LAD),left circumflex artery(LCX),right coronary artery(RCA)]was compared,and the correlation between pF AI and HT patients was analyzed.Results RCA-FAI(-78.86 HU±7.66 HU)and LAD-FAI(-80.62 HU±7.50 HU)were higher in HT group than those in control group(-84.46 HU± 8.00 HU,-83.43 HU±7.51 HU,P＜0.05).pFAI value was higher in grade 3 HT group than that in grade 1 HT group and grade 2 HT group(P＜0.05),while there were no differences between grade 1 HT group and grade 2 HT group(P＞0.05).After adjusting the influence of traditional risk factors and coronaryartery disease,RCA-FAI had relatively closer relationship with HT grades(r=0.47,P＜0.001).Conclusion LAD-FAI,RCA-FAI in the HT group are higher than those in control group and RCA-FAI has relatively closer relationship with HT grades,suggesting that RCA-FAI may be an imaging indicator to evaluate the pro-gression of HT and predict the risk of HT.
ABSTRACT
【Objective】 To analyze the expression of lncRNA SNHG25 in prostate cancer and its significance, so as to explore the biomarkers and potential therapeutic targets for the diagnosis and prognosis of this disease. 【Methods】 Based on the TCGA database, differential, survival, and clinical correlation analyses of SNHG25 were performed.SNHG25 expression in prostate cancer was analyzed in the UALCAN database to determine its relationship with the clinical and pathological characteristics.The lncRNA-miRNA-mRNA correlation analysis was performed.The relevant ceRNA regulatory network was constructed.Prostate cancer samples were divided into high and low SNHG25 expression groups, and differential SNHG25 related genes were filtered and then enriched. 【Results】 SNHG25 expression was significantly upregulated in prostate cancer specimens compared to normal prostate specimens (P0.05).Regulatory networks of SNHG25/miR-330-3p/DLX1 and RPL22L1 were constructed. 【Conclusion】 SNHG25 is highly expressed in prostate cancer tissues and correlated with poor prognosis.SNHG25 expression does not significantly correlate with age, T-stage, N-stage, and Gleason score.SNHG25/miR-330-3p/DLX1 and RPL22L1 regulatory networks may play an important role in the development of prostate cancer.SNHG25 may become a biomarker and potential therapeutic target for prostate cancer.
ABSTRACT
Background Experimental studies have shown that radiofrequency electromagnetic waves emitted by mobile phones can cause adverse effects on male reproductive health, including decreased semen quality and altered sex hormones. However, the results of epidemiological studies on the relationship between mobile phone use and male semen quality are inconsistent. Furthermore, there are few epidemiological studies on the association of mobile phone use with sex hormones. Objective To explore the associations of mobile phone use with male semen quality and sex hormones. Methods A total of 2045 men visited the reproductive medicine center of a hospital in Wuhan and ordered infertility examination were recruited from December 2018 to January 2020. Information on mobile phone use was obtained using a questionnaire. Among them, 1232 and 1694 men were eligible for semen quality analyses and sex hormone analyses, respectively. Multiple linear and logistic regression models were used to analyze the associations of mobile phone use with male semen quality and sex hormones. Results After adjusting for potential confounders, there was no statistically significant associations of mobile phone use with sperm progressive motility, sperm total motility, sperm concentration, sperm count, or serum luteinizing hormone (P>0.05). However, serum total testosterone showed a declined tendency with increasing daily duration of mobile phone use (Ptrend=0.08). Compared with men with daily mobile phone use of 0-2 h, men with daily mobile phone use of 2.1-5, 5.1-8, and >8 h showed decreased serum total testosterone concentrations by 6.29% (95%CI: 0.40%-11.84%), 6.01% (95%CI: 0.60%-12.19%), and 7.87% (95%CI: 0.40%-14.79%), respectively. Conclusion Mobile phone use is not associated with male semen quality and serum luteinizing hormone, but increasing daily duration of mobile phone use is potentially associated with a tendency to lower male serum total testosterone.

ABSTRACT
Objective:To investigate the immunoregulatory effects of Glycyrrhiza uralensis ethanol extract(GUEE) on the maturation of dendritic cells (DCs) and the adjuvant effect of GUEE on OVA in na?ve BALB/c mice and an ovalbumin (OVA)-induced asthma mouse model. Methods:GUEE was prepared, and the effects of different concentrations of GUEE on the maturation of DCs and the secreted cytokines as well as the effects of GUEE on bacterial lipopolysaccharide (LPS)-induced DC maturation were examined in vitro. The effect of GUEE on the morphology of mouse bone marrow derived DCs was observed using microscopy. Molecular expression levels on the surface of DCs were detected using flow cytometry. The levels of interleukin-1β (IL-1β), IL-6, IL-12, and tumor necrosis factor-α (TNF-α) in the supernatant of DCs cultures were measured by enzyme-linked immunosorbent assay (ELISA). The maturation status of DCs was detected by flow cytometry by injecting different concentrations of GUEE into the paws of mice and isolating the draining lymph nodes 24 h later. The naive BALB/c mice were co-immunized with OVA, and the changes in regulatory T cells (Treg) were detected by flow cytometry. An OVA-protein-induced mouse asthma model was established to investigate whether GUEE as a tolerogenic adjuvant has an antigen-specific therapeutic effect on asthmatic mice. Pulmonary pathological changes were analyzed by hematoxylin-eosin staining (HE) and PAS staining. OVA-specific antibodies in serum and the frequencies of Tregs, CD4 + IFN-γ + and CD4 + IL-4 + T cells in the spleen were detected by ELISA and flow cytometry, respectively. Results:GUEE suppressed DCs maturation induced by LPS both in vitro and in vivo (all P<0.05), and reduced proinflammatory cytokine production, including IL-1β, IL-6, IL-12 and TNF-α in the absence or presence of LPS (all P<0.05). Moreover, co-immunization with OVA and GUEE increased the amount of Tregs in na?ve BALB/c mice ( P<0.05). In OVA-induced asthmatic mice, OVA and GUEE co-immunization and GUEE alone treatment substantially ameliorated the inflammation of lung tissues, decreased the levels of IgG 1 and the amount of CD4 + IL-4 + T cells, and increased the amount of Tregs (all P<0.05). Conclusions:GUEE alone or as the tolerogenic adjuvant can ameliorate allergic diseases through inhibition of DC maturation and type 2 helper T cell responses and induction of Tregs.
ABSTRACT
Objective:Based on the clinical indicators of severe community-acquired pneumonia in emergency department, the early warning indicators of critical condition were constructed.Methods:The general information, vital signs before entering ICU, laboratory indexes and the survival rate in 30 days of 118 patients with community-acquired pneumonia were retrospectively collected in the emergency care unit of Peking Union Medical College Hospital from January to December 2018. The indexes of death patients (24 cases) and alive patients (98 cases) underwent comparative analysis, using ROC curve to predict the clinical outcome and reliable parameters of emergency patients with community-acquired pneumonia. The best cutoff value was determined according to Youden index and then undergoing multiple factors Logistic stepwise regression analysis. Then early warning model of critical degree was finally built.Results:Eleven indicators were used to predict the criticality of patients with acute community-acquired pneumonia, including AVPU (alert, voice, pain, unresponsive) score, Glasgow Coma Scale(GCS), heart rate, pulse oxygen saturation (SpO 2), fraction of inspiration O 2, oxygenation index,potential of hydrogen, blood potassium (K +), bilirubin, urea nitrogen, and C reactive protein, the optimal cutoff values were 2 points, 8 points, 91 times per minute, 0.94, 41%, 81.20%, 7.38, 4.0 mmol/L, 10.90 μmol/L, 2.23 mmol/L, and 41.5 mg/L. Multiple Logistic stepwise regression showed that the independent factors for predicting death were GCS score, SpO 2 and urea nitrogen, and the predictive ability of the early-warning model was 83.7%. Conclusions:GCS score, SpO 2 and urea nitrogen are effective early warning indicators for the severity of severe community-acquired pneumonia in emergency department, which are conducive to the rapid and efficient early identification and treatment of critically ill patients. Therefore, they are worthy of promotion and application in clinical practice.
ABSTRACT
Background@#Bovine group A rotavirus (BoRVA) is a major cause of severe gastroenteritis in newborn dairy calves. Only one study has investigated the G and P genotypes among dairy calves in a few regions of China, which were G6 and P[5]. Therefore, data on the prevalence and molecular characteristics of BoRVA in dairy calves in China remains limited. @*Objectives@#The purpose of this study was to investigate the prevalence and molecular characteristics of BoRVA in dairy calves in China. @*Methods@#269 dairy calves diarrheic samples from 23 farms in six provinces in China were collected to detect BoRVA using reverse transcription polymerase chain reaction. @*Results@#71% of samples were determined to be BoRVA-positive. Two G genotypes (G6, G10) and two P genotypes (P[1], P[5]) were identified, and G6P[1] BoRVA was the predominant strain. Moreover, the VP7 and VP4 gene sequences of these dairy calf BoRVA strains revealed abundant genetic diversity. Interestingly, eight out of 17 complete G6 VP7 sequences were clustered into G6 lineage VI and analysis showed the strains were closely related to Chinese yak BoRVA strains. @*Conclusions@#The results of this study show that BoRVA circulates widely among dairy calves in China, and the dominant genotype in circulation is G6P[1], first report on molecular characteristics of complete P[5] VP4 genes in chinese dairy calves. These results will help us to further understand the prevalence and genetic evolution of BoRVA among dairy calves in China and, thus, prevent the disease more effectively.

ABSTRACT
Objective:To compare the efficacy of HES 130/0.4 and acetate Ringer′s solution (A-HES) and HES 130/0.4 and normal saline (NS-HES) for volume therapy in the patients undergoing non-cardiac surgery with general anesthesia.Methods:Two hundred and fifty American Society of Anesthesiologist physical status Ⅰ or Ⅱ patients of both sexes, aged 18-64 yr, with body mass index of 18-32 kg/m 2, undergoing noncardiac surgery with general anesthesia, were divided into group A-HES and group NS-HES using the stratified block randomization technique.A-HES and NS-HES 15 ml/kg were intravenously infused over 1 h immediately after induction of anesthesia in A-HES and NS-HES groups, respectively.Mean arterial pressure (MAP), heart rate (HR) and central venous pressure (CVP) were recorded before and after infusion, and the maximum changing rate of MAP and HR and the maximum change in CVP were calculated.The pH value, BE and HCO 3- were recorded before infusion and at 15 min after the end of infusion, and Hb, Hct, electrolytes, blood glucose, blood biochemical parameters and parameters of coagulation function were measured.The occurrence of abnormal blood biochemical parameters, blood glucose, and parameters of coagulation function, intraoperative requirement for vasoactive drugs, occurrence of HES-related adverse events, and intraoperative fluid intake and output were recorded. Results:A total of 251 cases were actually enrolled in this study, with 125 cases in group A-HES, and 126 cases in group NS-HES.Compared with group NS-HES, no significant change was found in the maximum changing rate of MAP and HR and the maximum change in CVP ( P>0.05) in group A-HES, and non-inferiority analysis showed that group A-HES was not inferior to group NS-HES.Compared with group NS-HES, the concentrations of BE and HCO 3-, K + , Ca 2+ and Mg 2+ were significantly increased, the concentrations of Na + and Cl - were decreased, the PT was shortened, the incidence of abnormal PT was decreased at 15 min after the end of infusion ( P< 0.05), and no significant change was found in the other parameters mentioned above in group A-HES ( P>0.05). Conclusion:The volume expanding effect of A-HES and its effect on liver and kidney function are not significantly different from those of NS-HES, however, A-HES has certain advantages in maintaining acid-base balance, electrolyte stability and coagulation function.
ABSTRACT
Pediatric cough is a heterogeneous condition in terms of symptoms and the underlying disease mechanisms. Symptom phenotypes hold complicated interactions between each other to form an intricate network structure. This study aims to investigate whether the network structure of pediatric cough symptoms is associated with the prognosis and outcome of patients. A total of 384 cases were derived from the electronic medical records of a highly experienced traditional Chinese medicine (TCM) physician. The data were divided into two groups according to the therapeutic effect, namely, an invalid group (group A with 40 cases of poor efficacy) and a valid group (group B with 344 cases of good efficacy). Several well-established analysis methods, namely, statistical test, correlation analysis, and complex network analysis, were used to analyze the data. This study reports that symptom networks of patients with pediatric cough are related to the effectiveness of treatment: a dense network of symptoms is associated with great difficulty in treatment. Interventions with the most different symptoms in the symptom network may have improved therapeutic effects.

ABSTRACT
Objective To explore the risk stratification of pulse oxygen saturation (SpO2) in patients with emergency hypoxemia patients, and to provide evidence for the identification of critical illness. Methods Self-designed clinical data registration form for patients with emergency hypoxemia , and prospective collection of 344 hypoxemia patients in the emergency department of Peking Union Medical College Hospital from March to April in 2018, including baseline data (name, gender, age, ID number, date, registration time), hospitalization method, past history, patient complaint and diagnosis, triage level, SpO2, whether to enter the rescue room, etc. Results All of 344 emergency hypoxemia patients, there were 163 cases (21.2% ) of ambulances, and 107 cases (31.1% ) of patients requiring immediate rescue. There were 54 cases (25.7%) and 53 cases (39.6%) in need of immediate rescue in day shift (8:00-20:00) and night shift (20:00-8:00 next day), with 9:00-10:00, 14:00-15:00, 20:00-24:00 in the majority. There was a statistical difference in the way of hospitalization, triage, and SpO(2 25.780, t=4.722, all P<0.05). SpO2 risk stratification was 0.905 in patients without pulmonary disease, and SpO2 risk stratification in patients with lung disease was 0.765. Conclusions Patients with hypoxemia account for a certain proportion in the emergency department and are in critical condition. The degree of critical condition of patients can be evaluated based on whether they have lung diseases, and the risk stratification of patients can be accurately determined with the help of SpO2, so as to further guide the hierarchical treatment measures for patients with emergency hypoxemia and rationally optimize the χ2=29.537, allocation of emergency resources.

ABSTRACT
Objective: To evaluate the effect of butyphthalide in the treatment of massive cerebral infarction
Methods: One hundred and twenty patients with massive cerebral infarction who were admitted to the hospital between January 2017 and December 2017 were selected and divided into a treatment group [n = 60] and a control group [n = 60] using random number table, 80 each group. Patients in the control group were given conventional cerebral infarction therapy, while patients in the treatment group were given butyphthalide injection besides the conventional treatment. The National Institutes of Health Stroke Scale [NIHSS] score, score of activity of daily living [ADL], lipoprotein-associated phospholipase A2 [LP-PLA2] and prognosis were recorded and compared between the two groups. The response rates of the two groups were recorded
Results: The total response rates of the control group and treatment group were 73.85% and 93.85% respectively at the postoperative 21st day, and the difference had statistical significance [P<0.05]. The NIHSS score of the two groups obviously decreased, and the ADL score significantly increased after treatment; the differences of NIHSS score and ADL score before and after treatment in the same group had statistical significance [P<0.05]. The improvement of the indexes of the treatment group was obviously superior to that of the control group, and the differences between the two groups had statistical significance [P<0.05]. The level of LP-PLA2 of both groups significantly decreased at the postoperative 21st day, and the difference before and after treatment in the same group was statistically significant [P<0.05]; the treatment group had a significantly lower level of LP-PLA2 than the control group, and the difference had statistical significance [P<0.05]. The treatment group had significantly higher positive outcome rate and lower mortality rate than the control group at the postoperative 90th day, and the differences had statistical significance [P<0.05]. The incidence of adverse events of the treatment group and control group was 8.3% [5/60] and 5.0% [3/60] respectively, suggesting no significant difference [P>0.05]
Conclusion: Butyphthalide has a favourable effect in treating massive cerebral infarction. It can repair neurologic impairment, improve activity of daily living, and adjust the level of LP-PLA2, suggesting favourable application values
