RESUMO

Objective To evaluate the value of dual-source CT angiography for evaluating the degree of coronary stenosis. Methods A total of 110 patients with a high likelihood of coronary stenosis identified by dual-source CT angiography or conventional coronary angiography were enrolled. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of dual-source CT angiography for diagnosis of coronary stenosis were evaluated with conventional coronary angiography as a gold standard. The agreement between dual-source CT angiography and conventional coronary angiography for evaluation of coronary stenosis was evaluated using Kappa statistic. Results A total of 1 401 coronary artery segments from 110 patients were displayed on conventional coronary angiography, while 1 382 segments were successfully visualized in dual-source CT angiography (98.64%). The sensitivity, specificity, positive predictive value and negative predictive value of dual-source CT angiography were 97.9%, 97.3%, 90.4% and 99.4% for diagnosis of coronary stenosis, and there was high consistence between dual-source CT angiography and conventional coronary angiography for grading coronary stenosis (Kappa statistic = 0.87, U = 58.36, P < 0.01). In addition, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of dual-source CT angiography were 94.7%, 96.8%, 83.7%, 99.0% and 96.5% for grading stenosis of coronary artery segments. Conclusion Dual-source CT angiography is accurate and reliable for diagnosis of coronary stenosis, which may be a non-invasive tool for assessment of coronary stenosis.

RESUMO

Objective: To identify the expression profile of circular RNA (circRNA) in placenta of pre-eclampsia (PE) pregnant women by high-throughput sequencing, and to construct the circRNA-microRNA (miRNA)-messenger RNA (mRNA) interaction network, so as to reveal the related pathways and regulatory mechanisms of PE. Methods: The clinical data and placentas of 42 women with PE (PE group) and 30 normal pregnant women (control group) who delivered in West China Second University Hospital from November 2019 to June 2021 were collected. (1) High-throughput sequencing was used to establish the differentially expressed circRNA profiles in placental tissues of 5 pairs of PE group and the control group. (2) Real-time quantitative PCR (qRT-PCR) was used to verify the expression levels of 6 differentially expressed circRNAs in placental tissues of PE group and control group. (3) Bioinformatics analysis was used to predict the target miRNA and analyze the co-expressed mRNA to construct a competitive endogenous RNA (ceRNA) network. The differentially expressed circRNAs were analyzed by Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathways. (4) Logistic regression analysis, Pearson correlation and Kendall's tau-b correlation analysis were used to test the correlation between the three differentially expressed circRNAs and the risk of PE and clinical characteristics. (5) circRNA_05393 was selected for subsequent functional study. Small interfering RNA (siRNA) and overexpression plasmid were used to knock down or increase the expression level of circRNA_05393 in trophoblast cell line HTR-8/SVneo cells, respectively. Transwell assay was used to detect the migration and invasion ability of the trophoblasts in vitro. Cell counting kit-8 assay was used to detect the proliferation ability of the trophoblasts. Results: (1) Seventy-two differentially expressed circRNAs were identified by high-throughput sequencing, of which 35 were up-regulated and 37 were down-regulated. (2) qRT-PCR showed that compared with the control group, circRNA_00673 (1.306±0.168 vs 2.059±0.242; t=2.356, P=0.021) and circRNA_07796 (1.275±0.232 vs 1.954±0.230; t=2.018, P=0.047) were significantly increased, while circRNA_05393 (1.846±0.377 vs 0.790±0.094; t=3.138, P=0.002) was significantly decreased. (3) The circRNA-miRNA-mRNA interaction network contained 3 circRNAs, 8 miRNAs and 53 mRNAs. GO functional annotation analysis showed that the biological process was mainly enriched in iron ion homeostasis, membrane depolarization during action potential and neuronal action potential. In terms of cellular components, they were mainly enriched in cytoskeleton and membrane components. In terms of molecular function, they were mainly enriched in the activity of voltage-gated sodium channel and basic amino acid transmembrane transporter. KEGG pathway enrichment analysis showed that mRNAs in the interaction network were mainly enriched in complement and coagulation cascade, glycine, serine and threonine metabolism, p53 signaling pathway and peroxisome proliferators-activated receptors (PPAR) signaling pathway. (4) Logistic regression analysis showed that down-regulation of circRNA_05393 expression was a risk factor for PE (OR=0.044, 95%CI: 0.003-0.596; P=0.019). Correlation analysis showed that circRNA_05393 was significantly correlated with systolic blood pressure and diastolic blood pressure in PE pregnant women (both P<0.05). (5) Knock down or overexpression of circRNA_05393 significantly reduced or increased the migration and invasion abilities of HTR-8/SVneo cells (all P<0.05), but had no significant effect on the ability of tube formation and proliferation (all P>0.05). Conclusions: The construction of circRNA expression profile in placenta and the exploration of circRNA-miRNA-mRNA interaction network provide the possibility to reveal the regulatory mechanism of specific circRNA involved in PE. Inhibition of circRNA_05393 may induce the progression of PE by reducing the migration and invasion of trophoblasts.

RESUMO

Objective:To analyze the characteristics of immune cross-reaction between herpes simplex virus type 1 (HSV-1) and HSV-2 in terms of serology and clinical protection aiming to provide data for the control and prevention of diseases caused by the two viruses.Methods:An attenuated HSV-1 strain M3 was used to immunize BALB/c mice. Specific immune responses indicated by the production of neutralizing antibodies were detected. Wild-type HSV-1 and HSV-2 strains were respectively used to infect the mice through different ways 28 d after the immunization to observe the protective immunity in the M3-immunized mice against HSV-1/2 infection.Results:M3 strain could not induce specific neutralizing antibodies against HSV-2. Therefore, viral loads in tissues of the immunized mice increased significantly following different modes of HSV-2 exposure. However, no obvious abnormal clinical manifestations were found and the histopathological damage was only slight inflammatory reaction. In contrast, HSV-1-specific neutralizing antibodies were elicited in the M3-immunizaed mice with significant protective effects against HSV-1 infection.Conclusions:The immune response induced by attenuated HSV-1 strain M3 in mice exhibited immune-protective effects characterized by production of neutralizing antibodies and inhibition of virus proliferation in vivo against wild-type HSV-1 infection. For HSV-2, instead of neutralizing virus in form of antibodies, it featured by more of clinical cross-immunoprotective abilities to control virus growth.

RESUMO

BACKGROUNDIn-depth investigations of the safety and immunogenicity of inactivated SARS-CoV-2 vaccines are needed. METHODIn a phase I randomized, double-blinded, and placebo-controlled trial involving 192 healthy adults 18-59 years of age, two injections of three different doses (50 EU, 100 EU and 150 EU) of an inactivated SARS-CoV-2 vaccine or the placebo were administered intramuscularly with a 2- or 4-week interval between the injections. The safety and immunogenicity of the vaccine were evaluated within 28 days. FINDINGIn this study, 191 subjects assigned to three doses groups or the placebo group completed the 28-day trial. There were 44 adverse reactions within the 28 days, most commonly mild pain and redness at the injection site or slight fatigue, and no abnormal variations were observed in 48 cytokines in the serum samples of immunized subjects. The serum samples diluted from 1:32 to 1:4096 and incubated with the virus did not show antibody-dependent enhancement effects (ADEs) with regard to human natural killer cells, macrophages or dendritic cells. At day 14, the seroconversion rates had reached 92%, 100% and 96% with geometric mean titers (GMTs) of 18.0, 54.5 and 37.1, and at day 28, the seroconversion rates had reached 80%, 96% and 92% with GMTs of 10.6, 15.4 and 19.6in 0, 14 and 0, 28 procedures, respectively. Seroconversion was associated with the synchronous upregulation of ELISA antibodies against the S protein, N protein and virion and a cytotoxic T lymphocyte (CTL) response. Transcriptome analysis shaped the genetic diversity of immune response induced by the vaccine. INTERPRETATIONIn a population aged 18-59 years, this inactivated SARS-CoV-2 vaccine was safe and immunogenic. Trial registrationNCT04412538 FUNDINGThe National Key R&D Program of China (2020YFC0849700), the Program of Chinese Academy of Medicine Science and the Major Science and Technology Special Projects of Yunnan Province.

RESUMO

With the relatively serious global epidemic outbreak of SARS-CoV-2 infection, public concerns focus on not only clinical therapeutic measures and public quarantine for this disease but also the development of vaccines. The technical design of our SARS-CoV-2 inactivated vaccine provides a viral antigen that enables the exposure of more than one structural protein based upon the antibody composition of COVID-19 patients convalescent serum. This design led to valid immunity with increasing neutralizing antibody titers and a CTL response detected post-immunization of this vaccine by two injections in rhesus macaques. Further, this elicited immunoprotection in macaques enables not only to restrain completely viral replication in tissues of immunized animals, compared to the adjuvant control and those immunized by an RBD peptide vaccine, but also to significantly alleviate inflammatory lesion in lung tissues in histo-pathologic detection, compared to the adjuvant control with developed interstitial pneumonia. The data obtained from these macaques immunized with the inactivated vaccine or RBD peptide vaccine suggest that immunity with a clinically protective effect against SARS-CoV-2 infection should include not only specific neutralizing antibodies but also specific CTL responses against at least the S and N antigens.

RESUMO

Objective To observe and analyze the pathological changes in BALB/c mice infected with herpes simplex virus typeⅡ (HSV-2) through nasal and genital inoculation. Methods Six-week old female BALB/c mice were divided into two groups, experimental and control groups. In the experimental group, the mice were infected with HSV-2 (104 CCID50/20μl per mouse) through nasal and genital tract in-oculation. Accordingly, the mice in the control group were injected with equal volume of PBS. Tissue speci-mens were collected from lung, nervous system and reproductive system for pathological analysis and viral load detection at different time points after infection. Lat gene expression in mouse trigeminal and sacral gan-glia was detected through in situ hybridization. In addition, the proliferation of viruses isolated form trigemi-nal and sacral ganglia of the infected mice was observed in vitro. Results Weight loss and histopathological lesions were observed in the mice of the experimental group 6 d after infection. Major pathological changes in the HSV-2-infected mice through nasal tract inoculation involved the lung and central nervous system( CNS) , including alveolar wall congestion, cerebrovascular cuff response and lymphocyte infiltration. How-ever, the major lesions in the infected mice through genital tract inoculation were found in the reproductive ducts, such as sacral ganglion necrosis, eosinophilia in the vagina and uterus, and ovarian congestion. Re-sults of the viral load detection in tissues and organs of the infected mice were consistent with the pathological changes. The mice infected through nasal tract inoculation had significantly higher viral loads in the nerves and lungs than those by genital tract inoculation, but lower viral loads in the genital tracts and sacral ganglia. Positive expression of lat gene at mRNA level was detected in the trigeminal and sacral ganglia of mice with HSV-2 latency 28 d after infection. In addition, both of the tissue fragments from trigeminal and sacral ganglia had cytopathic effects ( CPEs) on Vero cells. Enhanced expression of lat gene at mRNA level and much severer CPEs were induced by genital tract inoculation than by nasal tract inoculation. Conclu-sions HSV-2 could infect and cause histopathological damages in BALB/c mice through both nasal and genital tracts. In addition, the locations of the pathological lesions were closely related to the mode of infection.

RESUMO

Objective To investigate the influences of herpes simplex virus 1 and 2 ( HSV1 and HSV2) infection on the expression of signaling molecules associated with innate immune response in respira-tory and vaginal epithelial cells for bettering understanding of HSV infection and pathological characteristics in the primary infection site, namely mucosal epithelial tissues. Methods KMB17 and VK2 cells were in-fected with HSV. Changes in cell morphology and inner structure after HSV infection were observed under optical microscope and scanning electron microscope, respectively. Viral proliferation in KMB17 and VK2 cells was detected by plaque assay, microcytopathic assay and real-time quantitative PCR. Expression of sig-naling molecules associated with innate immune response in virus-infected KMB17 and VK2 cells were ana-lyzed by real-time quantitative PCR. Results Both HSV1 and HSV2 could infect KMB17 and VK2 cells, and cause damage to cell morphology and inner structure after 12 hours. Both of the two viruses formed simi-lar plaque on the single layer of KMB17 and VK2 cells, although HSV2 proliferated slower than HSV1. There were differences in the expression of signaling molecules associated with innate immune response in-duced by the two viruses in KMB17 and VK2 cells. Conclusion Both HSV1 and HSV2 could infect and proliferate in epithelial cells ( KMB17 and VK2 cells) . Although there were slight differences in viral prolif-eration between them, significant differences in the expression of signaling molecules associated with innate immune response induced by the two viruses were observed.

RESUMO

Objective To study the cyfluthrin resistance and potential mechanisms of Anopheles sinensis in Nanchang Chang-bei International Airport,Nanchang City,Jiangxi Province. Methods The resistance levels of the local An. sinensis were de-tected by WHO drug resistance bioassay. During the bioassay,the dying mosquitos were classed as sensitive mosquitos,and the survival ones were classed as resistant mosquitos. The P450 monooxygenase activity and glutathione S-transferase activity were detected and compared between the two groups. At the same time,the death time of each sensitive mosquito was recorded,and the correlations between the death time and the P450 monooxygenase activity and glutathione S-transferase activity were ana-lyzed,respectively. Results The bioassay mortality of the local An. sinensis was 59.5%. The differences of the P450 monooxy-genase activities among the resistant mosquitos,sensitive mosquitos and laboratory sensitive mosquitos had statistical signifi-cances(F=151.89,Psensitive mosquitos>laboratory sensitive mosquitos. The differences of glutathione s-transferase activities among the three groups had no statistical significance(F=0.72,P=0.49). There existed positive correlation between the mosquito death time and the P450 monooxygenase activity,and the regression equation was y=79.479+1.512x with the correlation coefficient of 0.88,while there was no correlation between the mosquito death time and the glutathione S-transferaseactivity. Conclusion The An. sinensis in Nanchang Changbei International Airport has been resistant to cyfluthrin,and the promotion of P450 monooxygenase activity maybe one of the reasons for the resistance.

RESULTS: The bioassay mortality of the local An. sinensis was 59.5%. The differences of the P450 monooxygenase activities among the resistant mosquitos, sensitive mosquitos and laboratory sensitive mosquitos had statistical significances (F =151.89, P < 0.01), the resistant mosquitos > sensitive mosquitos > laboratory sensitive mosquitos. The differences of glutathione s-transferase activities among the three groups had no statistical significance (F = 0.72, P = 0.49). There existed positive correlation between the mosquito death time and the P450 monooxygenase activity, and the regression equation was y = 79.479 +1.512x with the correlation coefficient of 0.88, while there was no correlation between the mosquito death time and the glutathione S-transferaseactivity. CONCLUSIONS: The An. sinensis in Nanchang Changbei International Airport has been resistant to cyfluthrin, and the promotion of P450 monooxygenase activity maybe one of the reasons for the resistance.
