RESUMEN
Objective:To investigate the correlation between cytokeratin 19 fragment(CYFRA21-1), modified ultrasound B-line and connective tissue disease associated with interstitial lung disease (CTD-ILD).Methods:The data of 112 patients with CTD hospitalized in the Department of Rheumatology and Immunology of the Second Hospital of Fujian Medical University from September 2019 to December 2021 were retrospectively collected. Sixty patients in the CTD-ILD group and 52 patients in the connective tissue disease without interstitial lung disease (CTD-noILD) group were included. The t-test and χ2 test were used to compare the demographic characteristics and tumor-associated antigens of the two groups of patients. Modified ultrasound score and HRCT Warrick score were evaluated by Pearson correlation analysis. In addition, the relationship between CYFRA21-1, modified ultrasound score and Warrick score were evaluated, and the diagnostic efficacy of CYFRA21-1 and modified ultrasound of CTD-ILD was evaluated and analyzed by binary logistic regression analysis. Results:Patients in the CTD-ILD group had higher CYFRA21-1 concentrations than the CTD-no-ILD group[5.74(4.25, 9.79) ng/ml vs. 2.79(2.21, 3.23) ng/ml, Z=45.94, P<0.001], patients in the CTD-ILD group had higher modified ultrasound scores than the CTD-no-ILD group [44.5(36.5, 60.0) vs. 5.0 (3.2, 6.8), P<0.001]. Modified ultrasound score was positively correlated with Warrick score ( r=0.93, P<0.001) and CYRFA21-1 was positively correlated with modified ultrasound score ( r=0.39, P=0.042). The sensitivity of CYFRA21-1 in determining CTD-ILD was 81.7% and the specificity was 92.3% [ AUC (95% CI)=0.88(0.81, 0.95), P<0.001], the sensitivity of modified ultrasound B-line to determine CTD-ILD was 96.4% and the specificity was 92.9% [ AUC (95% CI)=0.99 (0.97, 1.00), P<0.001]. History of smoking[ OR(95% CI)=9.26(1.11, 77.12), P=0.040] and elevated CYFRA21-1 concentration[ OR(95% CI)=19.40(4.89, 76.95), P<0.001] were risk factors for CTD-ILD. Conclusion:CYFRA21-1 is expected to be a serum marker indicating concomitant ILD in patients with CTD. Modified ultrasound B-line to determine concomitant ILD in CTD patients has good diagnostic utility and can reflect the severity of pulmonary fibrosis in CTD-ILD patients.
RESUMEN
Coronary heart disease （CHD） with atherosclerosis is a common chronic disease worldwide， and anxiety and depression are potential and crucial risk factors for adverse prognosis in CHD. Chaihu Longgu Mulitang （CLMT）， first mentioned in the Shang Han Lun （《伤寒论》）， is a classic prescription for treating Shaoyang diseases combined with disturbance of the mind and spirit， with the effects of harmonizing Shaoyang and calming the mind. Current research on mechanisms has shown that CLMT can play a role in CHD complicated with anxiety and depression through multiple pathways， including regulating related signaling pathways， inhibiting the expression of inflammatory factors， improving oxidative stress damage， modulating neurotransmitter levels， suppressing the hypothalamic-pituitary-adrenal axis， promoting mobilization of mesenchymal stem cells from the bone marrow， and inhibiting platelet activation. Clinical studies have demonstrated that CLMT significantly improves symptoms such as angina and insomnia caused by CHD complicated with anxiety and depression， effectively reduces negative emotions， improves traditional Chinese medicine （TCM） syndrome scores， and decreases levels of inflammatory factors. Furthermore， it has fewer adverse reactions and higher safety than conventional western medicine treatments. This article provides a review of the mechanisms and clinical studies of CLMT in the treatment of CHD complicated with anxiety and depression based on a comprehensive analysis of literature from the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， PubMed， and other databases in the past 15 years， in order to provide references for further research on the use of CLMT in the management of CHD complicated with anxiety and depression.
RESUMEN
【Objective】 To investigate the effect of exosomes produced by hepatitis B virus (HBV)-infected cells on the phenotype and function of macrophages. 【Methods】 The exosomes secreted by HepAD38 cells, which were capable of producing HBV and HepG2 cells, were collected by ultracentrifugation combined with immunosorbent method.The quality and purity of the extracted exosomes were verified by nanoparticle tracking analysis (NTA), scanning electron microscope and Western blot.The M0 THP-1 macrophages differentiated by PMA were stimulated by HepAD38 derived- or HepG2 derived exosomes.Total RNA and protein samples were collected at different time points after stimulation.Real-time fluorescence quantitative PCR (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA) were used to detect cytokine mRNA and protein expressions, respectively.Meanwhile, neutral red assay was performed to analyze macrophage pinocytosis activity, and a commercial kit was used to measure reactive oxygen species (ROS) in THP-1 macrophages.Human reverse transcription chip detection was performed to obtain the microRNAs profile of the exosomes.And the effect of selected miRNA on macrophages was further confirmed by qRT-PCR. 【Results】 Compared with HepG2-derived exosomes, HepAD38-derived exosomes increased the mRNA and protein expressions of IL-1β, MCP-1 and TNFα significantly.However, no difference of pinocytosis capacity or ROS production was found between the HepAD38-derived exosomes group and HepG2-derived exosomes group.Human reverse transcription chip detection results were verified by KEGG analysis and qRT-PCR, and it was found that miR-6824-3p could also significantly increase the expression levels of IL-1β, MCP-1 and TNFα after high expression. 【Conclusion】 This study found that exosomes produced by HepAD38 cells may stimulate macrophages to produce inflammatory factors such as IL-1β, MCP-1 and TNFα through miR-6824-3p, thereby playing a role in HBV infection.
RESUMEN
【Objective】 To investigate the effect of transfusion-transmitted Zika virus (ZIKV) on the expression of non-coding circular RNA (hsa_circ_0001613) and the role of hsa_circ_0001613 in Zika virus replication. 【Methods】 Human adenocarcinomic alveolar basal epithelial cells (A549) were seeded on a 12-well plate at 1.8×105/ well and infected with ZIKV at 0.05 MOI. The Total RNAs were isolated every day for 5 days after infection, and the relative expression level of hsa_circ_0001613 was detected by qRT-PCR. In addition, 10nM siRNA-hsa_circ_0001613 was transfected into 2×105/ well A549 cells to specifically knock down the expression level of hsa_circ_0001613. 24h later, the cells were infected with ZIKV (MOI=0.05). Total RNAs were isolated at day 1-5 post-infection, proteins were extracted 96h post-infection. ZIKV replication, relative host antiviral gene expression, and interferon stimulated response element (ISRE) activity were tested using qRT-PCR, western blot and dual luciferase assay, respectively. 【Results】 The relative expression of hsa_circ_0001613 decreased significantly after 1-5 days of ZIKV infection. Knockdown of hsa_circ_0001613 inhibited ZIKV replication. Meanwhile, hsa_circ_0001613 knockdown significantly upregulated IFN-α/β and its downstream interferon-stimulated genes (ISGs) expression, also increased ISRE activity. 【Conclusion】 ZIKV infection significantly suppressed hsa_circ_0001613 expression in A4549 cells. Preliminary study indicated that hsa_circ_0001613 knockdown inhibited ZIKV replication possibly through activating type-Ⅰ IFN signaling pathway as showed by increased ISGs expression and ISRE activity.

RESUMEN
The transfusion-transmission risk associated with the major transfusion-relevant pathogens, such as hepatitis B virus, hepatitis C virus and human immunodeficiency virus, has been gradually reduced and maintained at a low level. There has been a growing awareness of the threat to blood safety from emerging andre-emerging infectious diseases, a number of which are known to be, such as plasmodium, human parvovirusB19, hepatitis E virus, dengue virus, human T-lymphocytic leukemia virus and West Nile virus, or are potentially transfusion transmissible, such as novel coronavirus. Among them, dengue virus was regional epidemic in China, and may outbreak again unpredictably in the future. Its threat to blood safety cannot be underestimated. At present, there are only four pathogen screening items for routine blood screening in China. Duetoan increasing number of emergingand re-emerging pathogens and the absence of screening strategies for new pathogens in blood centers, it would be a great challenge to blood safety in China. In this review, we documented the prevalence of several pathogens emerged in China, and discussed the impact on blood safety and the viability of personalized screening strategies foremerginginfectiouspathogens in blood centers.
RESUMEN
Objective:To explore the therapeutic effect of intra-articular injection of triptolide nanomaterials on rabbit antigen-induced knee arthritis.Methods:Twenty-seven New Zealand white rabbits were randomly divided into 4 groups. After antigen-induced arthritis (AIA) model were induced, the knee joints of triptolide nanomaterials (TPNA) group, triptolide (TP) group and betamethasone (BS) group were injected intra-articularly under ultrasound guidance with triptolide nanomaterials, triptolide and betamethasone respectively, 7 rabbits in each group. And the other 6 rabbits were punctured but not injected with any drugs as the control group. The pathological changes of joint swelling, synovitis and bone erosion were examined. Student's test, repeated measure data of analysis of variance (ANOVA), Mann-Whitney U test and Kruskal- Wallis test were used for statistical analysis. Results:① Before treatment, the knee joint diameters of the TPNA group, TP group, BS group and control group were (2.02±0.08) cm, (2.08±0.06) cm, (2.10±0.06) cm and (2.18±0.07) cm, respectively. After one week of administration, the knee joint diameters of the above groups were (1.85±0.06) cm, (1.89±0.07) cm, (1.93±0.08) cm and (2.15±0.08) cm, respectively. Knee joint swelling was significantly reduced in each treated group after a week of intra-articular injection. With the extension of treatment, the diameter of rabbit knee joints in each experimental group gradually decreased gradually ( F=58.83, P<0.01; F=53.78, P<0.01; F=68.24, P<0.01), and the diameter of rabbit knee joints in the TP group, TPNA group and BS group was significantly smaller than that of the control group ( F=63.83, P<0.01; F=71.94, P<0.01; F=140.79, P<0.01). ② The synovitis score of TP group was lower than that of the control group ( Z=-2.082, P<0.05), which was mainly mild synovitis. While the synovitis scores of TPNA group and BS group were lower than that of TP group ( Z=-2.082, P<0.05; Z=-2.687, P<0.05), most of which were free from synovitis. There was no statistical significant difference between BS group and TPNA group ( Z=-1.000, P>0.05). ③ The pathological scores of bone destruction in the TPNA group, TP group and BS group were all reduced compared with the control group ( Z=-2.505, P<0.05; Z=-2.216, P<0.05; Z=-2.505, P<0.05). There was no statistical significant difference between the TPNA group, TP group and BS group ( χ2=0.588, P>0.05). Conclusion:Intra-articular injection of triptolide nanomaterials can relieve joint swelling, reduce synovitis, and delay bone erosion. Its effect is similiar to glucocorticoid, better than simple triptolide. Triptolide nanomaterials have the potential to be an effective drug for arthritis by intra-articular injection.

After four weeks and eight weeks of treatment, one jalf of the rats of each group were selected respectively and tested for erectile function and then sacrificed for the detection of nNOS-containing nerve fibers by streptaridin-peroxidase immunohistochemistry techniques(SP method).</p><p><b>RESULTS</b>After four weeks, the erection frequency and the number of nNOS-containing never fibers in the sham operation group significantly increased compared with the other two groups, which showed no significant difference(P > 0.05). There was no significant difference in erection rate among the three groups. After eight weeks, the number of nNOS-containing never fibers in corpus carvosum in the internal iliac arterial ligation group decreased compared with the other two groups, between which there was no significant difference. And there was no significant difference in erection frequency and erection rate among the three groups.</p><p><b>CONCLUSION</b>Growth hormone can improve erectile function of internal iliac arterial ligation rats, which can be explained by the increase in the number of nNOS-containing never fibers in corpus carvosum of rats.</p>

The incidence of erectile dysfunction (ED) significantly increases in aging men, which may be associated with the decrease of the serum growth hormone (GH) level. GH may play an important role in the maintenance of penile erectile function, perhaps by promotion of the NO-cGMP pathway, stimulation of the regeneration of NOS-containing nerve fibers and the augmentation of androgenic action.
