ABSTRACT

Objective:To assess the safety and efficiency of left atrial appendage closure (LAAC) combined delayed anticoagulant therapy in atrial fibrillation (AF) patients combined with cardiogenic stroke during anticoagulant therapy.Methods:Using prospective research methods, 35 AF patients combined with cardiogenic stroke during anticoagulant therapy from September 2020 to June 2022 in Xuanwu Hospital, Capital Medical University were selected. All patients were treated with LAAC and delayed anticoagulant therapy. The endpoints were the safety and efficacy of LAAC combined with delayed anticoagulant therapy. The primary endpoint of efficacy was the composite endpoint of postoperative death, myocardial infarction, hemorrhagic stroke and systemic embolism. The safety endpoint was major bleeding as defined by the International Society for Thrombosis and Hemostasis and clinically relevant non-major bleeding.Results:Among 35 patients, 21 were males and 14 were females; the age was (68.5 ± 9.3) years old; the CHA 2DS 2-VASc score was 5 (4, 6) scores; the time to the last stroke was 95 (42, 98) d; the National Institutes of Health stroke scale score at the time of stroke was 3 (1, 6) scores. All patients successfully completed LAAC without perioperative instrument-surface thrombosis, death, new stroke or bleeding events. Thirty-two patients continued oral anticoagulant therapy 45 d after LAAC. The patients were followed up for (12.6 ± 4.3) months, 1 patient experienced recurrent ischemic stroke, 2 patients endured mucosal bleeding, there were no adverse events such as all-cause death, cardiovascular death, systemic embolism and hemorrhagic stroke. Conclusions:The LAAC combined delayed anticoagulant therapy is efficient and safe in patients with AF. For AF patients combined with cardiogenic stroke during anticoagulant therapy, LAAC combined with delayed anticoagulation therapy may be considered to further prevent ischemic stroke events.

ABSTRACT

Objective:To explore the protective effect of zonisamide (ZNS) on oxygen-glucose deprivation (OGD) cell model of traumatic brain injury (TBI), and its underlying mechanism.Methods:Human neuroblastoma cells (SH-SY5Y) were cultured in vitro and divided into the control group, OGD group, and drug administration group (OGD+ZNS group) according to the random number table method. The OGD method was used to establish a TBI cell model. After modeling, the cell activity, the release of lactate dehydrogenase (LDH), and β-galactosidase staining were detected to evaluate cell function and senescence. Additionally, mitochondrial morphology and potential membrane changes were observed using Mito Tracker Red and JC-1 mitochondrial membrane potential staining. ATP concentration was measured, and protein was extracted from SH-SY5Y cells and then subjected to Western blot analysis to detect endoplasmic reticulum stress-related markers, including glucose-regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), protein disulfide isomerase (PDI), and β-actin.Results:The OGD group had a significantly lower cell survival rate compared to the control group ( P<0.01), while the OGD+ZNS group had a significant higher cell survival rate than the OGD group ( P<0.01). The LDH release rate was significantly higher in the OGD group than in the control group ( P<0.01), while the OGD+ZNS group had a significant lower LDH release rate compared to the OGD group ( P<0.01). Moreover, the cell staining results indicated that compared to the control and OGD+ZNS groups, the cells in the OGD group exhibited significant damage and senescence with darker staining while the mitochondrial staining results demonstrated a significant reduction in mitochondrial linear junctions and decreased mitochondrial activity in the OGD group compared to the control and OGD+ZNS groups. Compared to the control and OGD+ZNS groups, the OGD group exhibited a significant reduction in mitochondrial staining red fluorescence, a significant increase in green fluorescence, and a significant decrease in mitochondrial membrane potential. The OGD group demonstrated a significant decrease in ATP concentration compared to the control group ( P<0.01), whereas the OGD+ZNS group exhibited a significant higher ATP concentration compared to the OGD group ( P<0.01). Western blot analysis revealed significant upregulation of GRP78, CHOP, and PDI in the OGD group compared to the control group (all P<0.05), while in the OGD+ZNS group, the expression levels of these proteins were significantly downregulated compared to the OGD group (all P<0.05). Conclusions:Zonisamide can protect OGD TBI cell model by preserving mitochondrial activity and inhibiting endoplasmic reticulum stress.

ABSTRACT

Objective@#This study aims to investigate the epidemiological distribution of HFMD and quantify the association of temperature with the incidence of children’s HFMD in Nanjing, China.@*Methods@#Daily counts of HFMD in children under 5 years and daily meteorological variables during 2011-2016 were obtained. Descriptive statistics were used to describe the epidemiological characteristics and distributed lag non linear model (DLNM) was used to assess the associations of temperature on HFMD cases.@*Results@#A total of 104 977 HFMD cases aged 0-5 years were reported in Nanjing during the study period and the male to female sex ratio was 1.49∶1. The average annual incidence was 213.5 per 100 000. A bimodal seasonal pattern was observed and the south and west were found to be the high incidence areas in the city. Of these laboratory confirmed enteroviruses positive cases, 32.5% cases were positive for EV-A71 infections, 29.1% cases were positive for CV-A16 infections and 38.4% cases were positive of other enteroviruses infections. The temperature HFMD relationships were non linear and showed obvious lag effects. The cumulative relative risk presented as an approximately inverted U shape over 14 days and peaked at 25.7 ℃ with value of 2.71(95%CI=1.93-3.81). Subgroup analyses revealed that males and children aged <1 year were more vulnerable to temperature variations.@*Conclusion@#Epidemiological characteristics of HFMD among children aged 0-5 years old in Nanjing presented temporal and regional distribution. The temperature has significant impact on children’s HFMD occurrence.

ABSTRACT

BACKGROUND@#Ankylosing spondylitis (AS) is a common chronic progressive rheumatic disease. The aim of this study was to explore factors influencing abnormal bone mineral density (BMD) in young and middle-aged patients with AS.@*METHODS@#From July 2014 to August 2018, hospitalized patients with AS and health examinees in the health examination center of our clinics, ranging in age from 20 to 50 years, were monitored. The BMD of the lumbar spine and femoral neck of AS patients and those of a healthy control group were measured using dual-energy X-ray absorption. The BMDs of AS patients were compared with respect to age, course of disease, iritis, smoking habits, sex, height, weight, body mass index (BMI), medication use, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), platelet volume, platelet count, uric acid (UA), alkaline phosphatase (AKP), and calcium ion levels. Single-nucleotide polymorphisms (SNPs) related to BMD were screened using genome-wide association analysis.@*RESULTS@#There was no statistical difference in the proportion of abnormal bone masses between the different body parts. The BMD of all bones in AS patients was lower than that in healthy controls (P < 0.05). Additionally, BMD was correlated with serum calcium and CRP in AS patients (P < 0.05), but not with age, platelet volume, platelet count, ESR, UA, AKP, height, weight, and BMI. The incidence of abnormal bone mass in AS patients was correlated with sex (P < 0.05), but not with medication use, iritis, or smoking. BMD of the lumbar spine in AS patients did not correlate linearly with the course of the disease, but BMD of the femoral neck correlated linearly with the course of the disease (P < 0.05). BMD was correlated with multiple SNPs in patients with AS. Lumbar BMD was correlated with rs7025373 and rs7848078. Femoral head BMD was correlated with 3:102157365, 3:102157417, rs1252202, rs1681355, rs3891857, rs7842614, and rs9870734, suggesting that genetic factors play a role in BMD in patients with AS.@*CONCLUSIONS@#The proportion of abnormal bone mass in AS patients was higher than that in healthy individuals of the same age. The factors related to BMD in patients with AS are gender, CRP, and blood calcium. The BMD of the femoral neck of AS patients decreases with the course of the disease, but BMD of the lumbar spine is not related to the course of the disease. BMD in AS patients is associated with multiple SNPs.

ABSTRACT

Objective:To investigate the significance of plasma pentraxin 3 (PTX3) in patients with secondary hemophagocytic lymphohistiocytosis (sHLH).Methods:Plasma PTX3 levels were tested by ELISA in 48 newly diagnosed sHLH patients, 18 healthy volunteers and 9 lymphoma controls in the First Affiliated Hospital of Nanjing Medical University from January 2017 to July 2019. Clinical parameters were collected, and the correlations with PTX3 levels were analyzed.Results:PTX3 level in newly diagnosed group was significantly higher than that of healthy control group [16.29(1.17-66.00) vs. 0.76(0.01-7.86) μg/L, P<0.01]. Patients with lymphoma-associated HLH(LHLH) had higher plasma level of PTX3 than Fhose with infection-associated HLH (IHLH) [24.29(3.36-66.00) vs. 9.56(1.17-36.50)μg/L, P<0.05]. Plasma PTX3 levels in 48 sHLH patients were positively correlated with serum ferritin ( P<0.05). Receiver operating characteristic (ROC) curve for plasma PTX3 levels of sHLH and healthy controls produced a cutoff value at 3.9 μg/L, with its 86.7% sensitivity and 94.4% specificity. And ROC analysis showed that PTX3 17.5 μg/L was the critical value for diagnosis of LHLH from non-LHLH group, that the sensitivity and specificity were 63.0% and 76.2% respectively. The 1-year overall survival (OS) rate in patients with PTX3≥17.5 μg/L was significantly lower in those with PTX3<17.5 μg/L (18.5% vs. 75.8%, P<0.01). Conclusion:These results indicate the potential of PTX3 as a biomarker for diagnosis and prognosis in patients with sHLH.

ABSTRACT

Purpose@#miR-205 is a tumor suppressor and plays an important role in tumor invasiveness. However, the role of miR-205 in human gastric cancer (GC) epithelial-mesenchymal transition (EMT) remains unclear. The aim of this study was to investigate the molecular mechanism of miR-205 in the regulation of EMT in GC invasion. @*Materials and Methods@#Quantitative polymerase chain reaction (qPCR) was used to detect the expression of miR-205 in GC. Further, the correlation between the pathological parameters and prognosis of GC was statistically analyzed. A transwell model was used to evaluate the effect of miR-205-3p on the invasion and migration of GC cells. qPCR, western blotting, and luciferase assay were performed to analyze the relationship and target effects between miR-205-3p and the expression of zinc finger electron box binding homologous box 1 (ZEB1) and 2 (ZEB2). @*Results@#We found that the levels of miR-205-3p were significantly lower (P<0.05) in GC tissues than in matched normal tissues. Additionally, the expression of miR-205-3p was related to the tumor invasion depth, lymph node metastasis, lymph node invasion, and tumor, node, metastasis stage. Patients with lower miR-205-3p expression levels in the tumors had a poorer prognosis. The in vitro assays indicated that miR-205-3p could affect the invasion ability and EMT of GC cells by targeting the expression of both ZEB1 and ZEB2. @*Conclusions@#miR-205-3p promotes GC progression and affects the prognosis of patients by targeting both ZEB1 and ZEB2 to directly influence EMT.

ABSTRACT

OBJECTIVE@#To investigate the expression and clinical significance of soluble B7-H3 (sB7-H3) in patients with secondary hemophagocytic lymphohistiocytosis (sHLH).@*METHODS@#The plasma samples of 85 newly diagnosed sHLH patients from December 2012 to April 2018 were collected. The patients were divided into lymphoma-related HLH(LHLH)group and infection-related HLH(IHLH)group. The expression of sB7-H3 in plasma was detected by ELISA, and the clinical data were collected for analysis. Fifteen healthy people were chosen as control group.@*RESULTS@#The expression level of sB7-H3 in lymphoma-related HLH and infection-related HLH group significant increased as compared with the control group, (P<0.05), and the expression level of sB7-H3 in lymphoma-related HLH group was significant higher than that in infection-related HLH group [(35.75± 9.90) vs (28.70±8.95) ng/ml)] (P<0.001). There were no significant statistical difference in the expression of some clinical factors (including age, fever, splenomegaly, ANC, Plt, FIB, calcium ion, serum albumin, LDH, serum ferritin, sCD25) in lymphoma-related HLH and infection-related HLH group (P>0.05). The evaluation of expression and significance of sB7-H3 in sHLH by using ROC curve, showed that the area under ROC curve comparison of patients in lymphoma-related HLH group and infection-related HLH group was 0.718 (95% CI 0.610-0.810) (P=0.0002), and predicting the sensitivity and specificity of the lymphoma-related HLH patients were 77.36% and 59.38%, respectively. The best cut-off value of patients in sB7-H3 was 29.81 ng/ml, the overall survival time of sB7-H3 high-expression group (≥29.81 ng/ml) was significant shorter than that in low-expression group (<29.81 ng/ml) (24 vs 440 d) (P<0.001). The clinical factors affecting the survival status of sHLH patients were neutrophils, albumin, serum ferritin, serum calcium ions and sB7-H3 levels.@*CONCLUSION@#sB7-H3 associates with poor prognosis of sHLH patients, and may be involved in disease progression.

ABSTRACT

Objective To understand the condition of tick carrying CRT(Candidatus rickettsia tarasevichiae) and compound infection with SFTSV(Sever fever thrombocytopenia syndrome virus) in Yanbian area of Jilin province. Methods Free ticks were collected from 6 counties including Yanji, Wangqing, Hunchun, Dunhua, Antu and Helong in the Korean Autonomous Prefecture of Jilin Province(Yanbian Prefecture) by using the flagging, and they were classified morphologically. The CRT and SFTSV in ticks were detected by Nest PCR(Nested polymerase chain reaction) and Real Time RT-PCR(Real-time Quantitative polymerase chain reaction) methods. Target DNA sequencing was performed for CRT positive products, and the homology of gene sequence and phylogenetic relationship were analyzed. Results A total of 1032 ticks were collected in this study, including ixodes persulcatus (35.56%) and dermacenter silvarum (20.64%). haemaphysalis japonica (20.45%), haemaphysalis longicornis (10.47%), haemaphysalis concinna (8.33%),others( 4.55%). The CRT was detected from the Ixodes persulcatus, Haemaphysalis longicornis, Haemaphysalis japonica Dermacentor silvarum. The MIR(Minimum infection rate per 100 ticks) of CRT was 10.47%.The SFTSV was detected from the Haemaphysalis-concinna, Haemaphysalis-japonica,Ixodes-persulcatus,Haemaphysalis-longicornis,Dermacentor-silvarum. The MIR of SFTSV was 2.52 %. Three species of ticks, including Ixodes persulcatus(2.45%), Haemaphysalis japonica(1.42%), and dermacentor silvarum(0.47%), had CRT and SFTSV compound infections, and the MIR of two pathogens compound infections was 1.26 %. In this study, the gene sequence of CRT positive PCR products ompA and 17kDa with nucleotide sequence of Xinyang plant of HeNan XinYang strain (KX365196.1),had homology of 100%. Phylogenetic analysis showed that CRT ompA and the HeNan XinYang strain (KX365196.1) gene sequences formed a cluster in Yanbian, while the 17 kDa gene formed an independent branch. Conclusions For the first time, CRT was detected from free ticks in Yanbian area of Jilin Province, and it was found that Ixodes persulcatus may be the main medium of transmission of the pathogen. At the same time, it was found that CRT and SFTSV have compound infection in ticks of Yanbian area. Therefore, it can be clearly identified that Yanbian area in Jilin Province is the natural source of CRT, and there are two pathogenic compound infections in the local ticks.

Objective To mastered the distribution characteristics of Haemaphysalis longicornis in the Tumen River basin along the border between Russia, Korea and Northeast China, and understand the status of Haemaphysalis longicornis carrying the virus of fever with thrombocytopenia syndrome (SFTS), then, isolate the virus and analyze its genetic characteristics. Method Ticks were collected from Hunchun, Tumen, Helong and Longjing cities in the Tumen River basin of Jilin Province from April to September, 2017. Haemaphysalis longicornis was selected and grouped. SFTS virus was detected by real-time quantitative polymerase chain reaction (RT-qPCR). Virus isolation was carried out in Vero cells, besides, S,M,L gene segments were amplified . The homology of S, M and L gene segments was compared, phylogenetic tree was established, and their gene characteristics were analyzed. Result Haemaphysalis longicornis mainly distributed in Hunchun and Tumen City in the lower reaches of Tumen River. It was the dominant species in the two counties, reaching 71.85% and 87.62% respectively. A virus named YBHC-TICK2-2017/CHINA was isolated from Haemaphysalis longicornis collected in Hunchun. The sequences of S segment (1 746 bp), M segment (3 336 bp) and L segment (6 376 bp) of the virus were 98.00%-99.00%, homologous to those of SFTS virus isolates from China and Korea recorded in National Center for Biotechnology Information (NCBI) Gen Bank. Phylogenetic tree analysis showed that the S segment gene sequence of the virus strain was divided into a cluster with Jilin strain (KT890282) in China, and M segment and L segment gene sequence with Jiangsu strain (KR230781) in China. Conclusions Haemaphysalis longicornis are widely distributed in the lower reaches of the Tumen river. It was the first time that SFTS virus was isolated from Haemaphysalis longicornis in this area, suggesting that this area is important for SFTS prevention.

ABSTRACT

Background@#Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This study assessed the efficacy and safety of tofacitinib in Chinese patients with RA enrolled in Phase 3 and long-term extension (LTE) studies.@*Methods@#ORAL Sync was a 1-year, randomized, placebo-controlled, Phase 3 trial. Patients received tofacitinib 5 or 10 mg twice daily (BID) or placebo advanced to tofacitinib 5 or 10 mg BID at 3 or 6 months. All patients remained on ≥1 background conventional synthetic disease-modifying antirheumatic drug. ORAL Sequel is an open-label LTE study (data-cut: March 2015; data collection and analyses were ongoing, and study database was not locked at the time of analysis; study was closed in 2017). Efficacy outcomes: American College of Rheumatology (ACR) 20/50/70 response rates and Disease Activity Score in 28 joints using erythrocyte sedimentation rate (DAS28-4 [ESR]). Patient- and physician-reported outcomes: Health Assessment Questionnaire-Disability Index (HAQ-DI), Patient and Physician Global Assessment of Arthritis, and pain (visual analog scale). Safety was assessed throughout.@*Results@#ORAL Sync included 218 patients; 192 were subsequently enrolled into ORAL Sequel. In ORAL Sync, more patients achieved ACR20 (tofacitinib 5 mg BID, 67.4%; 10 mg BID, 70.6%; placebo, 34.1%) and DAS28-4 (ESR) <2.6 (tofacitinib 5 mg BID, 7.1%; 10 mg BID, 13.1%; placebo, 2.3%) with tofacitinib versus placebo at Month 6. Mean changes from baseline in HAQ-DI were greater with tofacitinib versus placebo at Month 6. In ORAL Sequel, efficacy was consistent to Month 48. Incidence rates for adverse events of special interest in tofacitinib-treated patients were similar to the global population.@*Conclusions@#Tofacitinib significantly reduced signs/symptoms and improved physical function and quality of life in Chinese patients with moderate-to-severely active RA up to Month 48. The safety profile was consistent with the global population.@*Clinical Trial Identifier@#NCT00856544 and NCT00413699.

ABSTRACT

Hyperpolarization activated cyclic nucleotide-gated cation (HCN) channels are involved in neuronal rhythm regulation, synaptic activity, membrane resistance and dendritic integration due to their voltage-gated physiological properties. Recent studies have shown that HCN channels play an important role in central nervous system diseases, such as temporal lobe epilepsy, neuropathic pain, learning and memory disorder, substance abuse addiction and other related diseases. In this paper, we summarize the research progress of HCN channels in central nervous system diseases in recent years.

ABSTRACT

Objective To explore the relationship between the radiological characteristics and clinical and pathological manifestations of intracranial juvenile xanthogranuloma. Methods The radiological and clinical characteristics of two intracranial juvenile xanthogranuloma cases were analyzed respectively. In combination with reviewing literatures, the radiological characteristics and discipline of intracranial juvenile xanthogranuloma disease were also analyzed. Results Intracranial juvenile xanthogranuloma disease was accidently detected in one case. The other case was detected with headache and numbness in face. No abnormal sign was found in skin. On plain CT isodensity signals appeared and on contrast-enhanced CT homogeneous enhancement was found.On MR imaging,masses showed isointense signals on T1WI and iso-or hypo-intensity signals on T2WI, and enhanced homogeneously. Lesions were solitary or multiple in the external of brain. After operation intracranial juvenile xanthogranuloma was confirmed by pathology, and no recurrence occurred. Conclusion Intracranial juvenile xanthogranuloma is a kind of rarely encountered disease with typically radiological characteristics, which is difficult to detect before surgery and can be confirmed by post-operative pathological and immunohistochemical examinations.[Chinese Medical Equipment Journal,2018,39(5):71-74]
