ABSTRACT

Purpose@#To compare the results of computed tomography angiography (CTA), transesophageal echocardiography (TEE), and digital subtraction angiography (DSA) measurements and analyze their accuracy, correlation, and consistency in patients who have successfully undergone left atrial appendage closure (LAAC). @*Materials and Methods@#A total of 157 non-valvular atrial fibrillation (AF) patients who underwent LAAC with Watchman devices were included in the study. The maximum diameter and depth of LAA were recorded using CTA, TEE, and DSA. Correlations and agreements were compared. @*Results@#The LAAC procedure was performed successfully in all patients using the Watchman device. There was no significant difference between DSA and TEE measurements of the diameter of the LAA ostium. LAA ostium diameter obtained by CTA, however, was greater than that from DSA and TEE. Correlations were good between LAA ostium diameter measured by TEE, CTA, and DSA and Watchman device size. DSA measurements and actual device size showed the widest limits of agreement, followed by TEE; CTA measurements showed the narrowest limits of agreement. For LAA depth measurements, mean CTA measurements were higher than those of TEE and DSA. There was no significant difference in depth measurements among the three imaging modalities. @*Conclusion@#CTA, TEE, and DSA measurements exhibited good correlations with Watchman device size. The ostium diameter and depth of the LAA measured by CTA were greater than those measured by TEE and DSA. The relevance and concordance of CTA measurements were the strongest.

ABSTRACT

OBJECTIVE@#To investigate the clinical effect and safety of Chinese Children's Leukemia Group (CCLG)-ALL 2008 (high risk group) protocol in the treatment with childhood Mixed phenotype acute leukemia (MPAL).@*METHODS@#The clinical data of 15 new diagnosed patients with MPAL treated in our hospital from January 2013 to December 2017 were retrospectively analyzed, and received CCLG-ALL 2008 (high risk group) protocol chemotherapy.@*RESULTS@#One patient gave up treatment after diagnosed, and 14 children with MPAL after induction remission chemotherapy, 3 patients gave up, and 5 patients received consolidation chemotherapy, and 6 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT). The complete remission (CR) rate was 85.7% at d33 of induction remission chemotherapy. The serious adverse event and treatment-related mortality (TRM) rate was 71.4% and 14.3%, respectively. The recurrence rate was 21.4% and the median time of relapse was 12(9.7-18.4) months. Except for 4 patients who gave up treatment, the 5-year event-free survival (EFS) rate in the other 11 patients was (54.5±15.0)%. The 5 years EFS of 4 patients who received consolidation chemotherapy was significantly lower than the 6 patients who received allo-HSCT after CR (25.0%±21.7% vs 83.3%±15.2%, P=0.033).@*CONCLUSION@#The CCLG-ALL2008 (for high-risk group) protocol in treatment of children with MPAL can get a high CR rate, but also with a high incidence of SAE. The patients received allo-HSCT after CR may have a good prognosis.

ABSTRACT

In the treatment of hypertensive crisis, the novel Rho kinase inhibitor DL0805-2 can rapidly lower systematic blood pressure, reduce pulmonary artery pressure, and has a significant protective effect on lung injury. This experiment intends to evaluate the efficacy of DL0805-2 against pulmonary arterial hypertension (PAH) and preliminarily reveals its underlying mechanism. Animal welfare and experimental procedures are in accordance with the provision of the Animal Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences. Sprague Dawley (SD) rats were randomly divided into DL0805-2 low, medium, and high dose groups (1, 3, and 10 mg·kg-1), bosentan positive control group, model group, and blank control group. The drug was administered daily on the 7th day after model establishment by monocrotaline injection. On the 25th day of the experiment, relevant indicators were examined to observe the therapeutic effect of DL0805-2 on pulmonary hypertension. DL0805-2 significantly relieved the abnormal changes in the physiological parameters related to PAH induced by monocrotaline, including reducing right ventricular systolic pressure, alleviating cardiac damage caused by pressure overload, and reducing the levels of endothelin-1 and inflammatory factors in lung tissues. DL0805-2 also attenuated pulmonary arteries remodeling. It was preliminarily discovered that DL0805-2 exerts preventive and therapeutic effect on PAH through Rho-kinase pathway. Our results suggested that DL0805-2 had good therapeutic effects on monocrotaline-induced PAH rat model. It intervened early in the disease process, effectively prevented the development of the disease, and reduced the mortality of the diseased animals. The mechanism is related to Rho-kinase pathway.

ABSTRACT

As a common disease in nervous system, epilepsy is possessed of characteristics of high incidence, suddenness and recurrent seizures. Timely prediction with corresponding rescues and treatments can be regarded as effective countermeasure to epilepsy emergencies, while most accidental injuries can thus be avoided. Currently, how to use electroencephalogram (EEG) signals to predict seizure is becoming a highlight topic in epilepsy researches. In spite of significant progress that made, more efforts are still to be made before clinical applications. This paper reviews past epilepsy studies, including research records and critical technologies. Contributions of machine learning (ML) and deep learning (DL) on seizure predictions have been emphasized. Since feature selection and model generalization limit prediction ratings of conventional ML measures, DL based seizure predictions predominate future epilepsy studies. Consequently, more exploration may be vitally important for promoting clinical applications of epileptic seizure prediction.

ABSTRACT

Estrogen receptor (esr) mediates the effects of estrogen on the expression of related genes, thereby regulating the growth and reproduction of mammals. To investigate the effect of retrotransposon insertion polymorphism (RIP) of the porcine esr gene on porcine growth performance, retrotransposon insertion polymorphism of the esr gene were predicted by comparative genomics and bioinformatics, and PCR was used to verify the insertion polymorphisms in different porcine breeds. Finally, the correlation analysis between the genotypes and performance of Large White pigs was conducted. The results showed that four retrotransposon polymorphic sites were identified in the esr1 and esr2 genes, which are esr1-SINE- RIP1 located in intron 2 of the esr1 gene, esr1-LINE-RIP2 and RIP3-esr1- SINE located in intron 5 of the gene, and esr2-LINE-RIP located in intron 1 of the esr2 gene, respectively. Among them, insertion of a 287 bp of SINE into intron 2 of the esr1 gene significantly affected (P<0.05) the live back fat thickness and 100 kg body weight back fat thickness of Large White pigs. Moreover, the live back fat thickness and back fat thickness at 100 kg body weight of homozygous with insertion (SINE+/+) was significantly greater than that of heterozygous with insertion (SINE+/-) and homozygous without insertion (SINE-/-). Therefore, esr1-SINE-RIP1 could be used as a molecular marker to assist the selection of deposition traits in Large White pigs.

ABSTRACT

ObjectiveTo evaluate the effects of intranasal dexmedetomidine premedication on Sedation anxiety score, circulation index, drug dosage (atropine, sufentanil), and adverse reactions in patients undergoing strabismus surgery with local anesthesia. MethodsNinety patients undergoing strabismus surgery were enrolled and randomly divided into the dexmedetomidine group (n=45) and control group (n=45). 30min before the local anesthesia, dexmedetomidine was given intranasally with a dose of 2 μg/kg in the dexmedetomidine group, while the control group treated equal volume saline. The MAP and HR values before pre-dose (T0), 10 min (T1), 20 min (T2), and 30 min (T3) were recorded. The Ramsay score was calculated 30 minutes after administration. SAS scores were made 1 day before surgery and 1 day after surgery. Meanwhile, we measured the dosage of atropine, sufentanil, and the incidence of adverse reactions during surgery. ResultsThe HR and MAP of patients in the dexmedetomidine group were significantly lower than those in the control group at T2 and T3 (P<0.05). The SAS score of the dexmedetomidine group was significantly lower than that of the control group 1 day after the operation. There was no significant difference between the dexmedetomidine group and the control group in the dosage of atropine, the incidence of oculocardiac reflex (OCR), and respiratory depression. The dose of sufentanil in the dexmedetomidine group was lower than that of the control group. The incidence of nausea and vomiting in the control group was significantly higher than that of the dexmedetomidine group.Conclusion Dexmedetomidine (2 μg/kg) preoperative nasal drip has a good sedative effect without obvious adverse reactions and could be safely assisted in clinical anesthesia for patients undergoing local anesthesia correction surgery.

ABSTRACT

OBJECTIVE@#To investigate the clinical features and prognostic factors of childhood Burkitt Lymphoma/leukemia.@*METHODS@#The clinical data of 35 patients with newly-diagnosed childhood Burkitt lymphoma/leukemia from March 2011 to September 2017 in Fujian Medical University Union Hospital were retrospectively analyzed and summarized. Among 35 patients, 5 gave up treatment and one patient died of multiple organ failure before treatment, and 29 patients received CCCG-BNHL-2010 protocol chemotherapy.@*RESULTS@#The 35 cases of BL/L includsd 31 males and 4 females (M∶F=7.75∶1) with the median age of 5(2.0-11) years. Clinically, the common infiltration sites were as follows: abdominal organs (especially ileocecus, 21/35, 60%), bone marrow (21/35, 60%), faciomaxillary (10/35, 28.57%), and central nervous system (8/35, 22.85%). According to St. Jude staging system, 6 patients were grouped into stage Ⅱ, and 8 into stage Ⅲ and 21 into stage Ⅳ, among which the bone marrow blasts of 17 patients were more than 25%. The analysis of therapeutic efficacy and prognosis showed that in median follow up of 23.4 (5.3-86.4) months, 5 patients relapsed (5/29, 17.24%), the median relapsed time was 5.7 (3.9-7.2) months; tow-year overall survival (OS) rate and progression-free survival (PFS) rate was 79.2%±7.6% and 78.3%±7.9%, respectively. Univariate analysis showed that the 2-year OS and PFS in patients with LDH>2N, stage Ⅳ (bone marrow infiltration), central nervous system infiltration and no-CR after 2 courses of treatnent all were significantly lower than those in patients with LDH≤2N, stageⅡ-Ⅲ, without central nervous system infiltration as well as CR after 2 course of treatment (P values were 0.015, 0.015, 0.019 and 0.000, respectively). Cox regression analysis showed that no-CR after 2 course was an independent unfavorable prognostic factor (HR 0.34, 95%CI: 0.03-0.407).@*CONCLUSION@#The childhood Buruitts lymphoma/leukemia is more freguently seen in males and school-age children, Advanced stage, bone marrow and contral nervous system infitration are common at the first visit to doctor, moreover the Burkitt's lymphoma/leykemia present repid progression and dangerous feature. The current intensive chemotherapy (high dose of drugs and short course) possess the significant therapeutic efficacy for this disease, but the patients should have very poor prognosis if they can not achieve CR after 2 course of chemotherapy.

ABSTRACT

In this study, the mobilomes of nine teleost species were annotated by bioinformatics methods. Both of the mobilome size and constitute displayed a significant difference in 9 species of teleost fishes. The species of mobilome content ranking from high to low were zebrafish, medaka, tilapia, coelacanth, platyfish, cod, stickleback, tetradon and fugu. Mobilome content and genome size were positively correlated. The DNA transposons displayed higher diversity and larger variation in teleost (0.50% to 38.37%), was a major determinant of differences in teleost mobilomes, and hAT and Tc/Mariner superfamily were the major DNA transposons in teleost. RNA transposons also exhibited high diversity in teleost, LINE transposons accounted for 0.53% to 5.75% teleost genomic sequences, and 14 superfamilies were detected. L1, L2, RTE and Rex retrotransposons obtained significant amplification. While LTR displayed low amplification in most teleost with less than 2% of genome coverages, except in zebrafish and stickleback, where LTR reachs 5.58% and 2.51% of genome coverages respectively. And 6 LTR superfamilies (Copia, DIRS, ERV, Gypsy, Ngaro and Pao) were detected in the teleost, and Gypsy exhibits obvious amplication among them. While the SINE represents the weakest ampification types in teleost, only within zebrafish and coelacanth, it represents 3.28% and 5.64% of genome coverages, in the other 7 teleost, it occupies less than 1% of genomes, and tRNA, 5S and MIR families of SINE have a certain degree of amplification in some teleosts. This study shows that the teleost display high diversity and large variation of mobilome, there is a strong correlation with the size variations of genomes and mobilome contents in teleost, mobilome is an important factor in determining the teleost genome size.

ABSTRACT

OBJECTIVE Salvianolic acid A (SAA) is one of the most bioactive compounds from a traditional Chinese medicine called Dan Shen(Salvia Miltiorrhiza Bunge)and exhibits many pharmaco-logical activities.Previous studies have indicated that SAA may inhibit endothelial dysfunction and vascular remodeling in spontaneously hypertensive rats. However, whether SAA improves vascular remodeling induced by pulmonary arterial hypertension (PAH) remains unknown. In this study we examined whether SAA attenuated vascular remodeling in a PAH rat induced by monocrotaline(MCT),and elucidated the underlying mechanisms.METHODS PAH was induced in rats by injecting a single dose of monocrotaline (MCT 60 mg·kg-1).The rats were orally treated with either SAA(0.3,1,3 mg·kg-1·d-1)or a positive con-trol Bosentan(30 mg·kg-1·d-1)for 4 weeks.Echocardiography and hemodynamic measurements were performed on d 28.Then the hearts and lungs were harvested,the organ indices and pulmonary artery wall thickness were calculated,and biochemical and histochemical analysis were conducted.The levels of apoptotic and signaling proteins in the lungs were measured using immunoblotting.RESULTS Treatment with SAA effectively ameliorated MCT-induced pulmonary artery remodeling,pulmonary hemodynamic ab-normalities and the subsequent increases of right ventricular systolic pressure (RVSP). Furthermore, the treatments significantly attenuated MCT-induced hypertrophic damage of myocardium,parenchymal in-jury and collagen deposition in the lungs.Moreover,the treatments attenuated MCT-induced apoptosis and fibrosis in the lungs.The treatments partially restored MCT-induced reductions of bone morphoge-netic protein typeⅡ receptor (BMPRⅡ) and phosphorylated Smad1/5 in the lungs. CONCLUSION SAA ameliorates the pulmonary arterial remodeling in MCT-induced PAH rats most likely via activating the BMPRII-Smad pathway and inhibiting apoptosis.Thus,SAA may have therapeutic potential for the pa-tients at high risk of PAH.

ABSTRACT

OBJECTIVE To investigate the pharmacological effect and mechanism of Salvianolic acid A (SAA) on pulmonary vascular remodeling. METHODS In current study, we conducted a series of experiments to clarify the effect of SAA,a kind of polyphenol compound,in the process of EndMT in human pulmonary arterial endothelial cells and in vivo therapeutic efficacy on vascular remodeling in monocrotaline (MCT)-induced EndMT. EndMT was also induced by TGF-β1in human pulmonary arterial endothelial cells(HPAECs) in vitro.RESULTS SAA significantly attenuated EndMT,simul-taneously inhibited cell migration and reactive oxygen species(ROS)formation.In MCT-induced pulmonary arterial hypertension(PAH)model,SAA improved vascular function,decreased TGF-β1level and inhib-ited inflammation. Mechanistically, SAA stimulated Nrf2 translocation and subsequent heme oxygen-ase-1(HO-1)up-regulation.The effect of SAA on EndMT in vitro was abolished by ZnPP,a HO-1 inhibitor. CONCLUSION This study indicates a deleterious impact of oxidative stress on EndMT. Polyphenol antioxidant treatment may provide an adjunctive action to alleviate pulmonary vascular remodeling via inhibiting EndMT.

ABSTRACT

Objective To summarize the long-term outcomes and safety of childhood Hodgkin lymphoma (HL) with protocol ABVD. Methods The clinical data of 20 children with HL admitted to the Union Hospital of Fujian Medical University from July 2010 to June 2017 were retrospectively analyzed. Among the 20 children with HL, 15 were male and 5 were female. The median age of initial diagnosis was 6.5 years old (3-12 years old). The pathological types were as follow: 1 case was nodular lymphocyte-predominant HL (NLPHL) and 19 cases were classical HL (cHL), including 9 cases of mixed cell type, 9 cases of nodular sclerosis type and 1 case of lymphocyte rich type. Basing on Ann Arbor staging system, 1 patient was evaluated as stage Ⅰ, 4 patients were stage Ⅱ, 10 patients were stage Ⅲ, and 5 patients were stage Ⅳ. There were 3 patients in the low-risk group, 7 patients in the intermediate-risk group, and 10 patients in the high-risk group. There were 9 patients with B symptoms. All patients were treated with the ABVD regimen. Results All the 20 patients completed all chemotherapy courses. After 2 courses, the effective rate was 100%(20/20), including 12 cases of complete remission (CR) and 8 cases of partial remission (PR). After the treatment, 19 cases achieved CR, and at the end of the 6 courses, the evaluation showed that 1 case had residual lesions. Follow-up to February 2018, clinical symptoms of 18 cases achieved CR, 2 cases relapsed (all high-risk group); the median follow-up time was 42 months (10.1-87.9 months), the overall survival rate was 100 % (20/20), the estimated 5-year rate of freedom from treatment failure (FFTF) was (89.1 ±7.3) %.Conclusions According to the risk stratification, ABVD regimen has good safety and long-term efficacy for children with cHL. Even the patients in low-risk or intermediate-risk group do not achieve CR after 2 courses and do not receive radiotherapy, the prognosis of them is still good.

ABSTRACT

The International Pediatric Multiple Sclerosis Study Group (IPMSSG) put forward the 2007 version of the diagnostic criteria for multiple sclerosis and other immune-mediated demyelinating diseases of the central nervous system in children in 2007 ("2007 version" for short). In 2012, IPMSSG proposed the new diagnostic criteria with reference to the latest research achievements of 150 members ("2012 version" for short). The 2012 version of the consensus statements covers the diagnostic criteria for acute disseminated encephalomyelitis, clinically isolated syndrome, neuromyelitis optica, and multiple sclerosis in children. As the two IPMSSG members in China, the authors give an interpretation of the 2012 version of the consensus statements with reference to related literature and clinical and scientific experience. The authors focus on how the 2012 version comprehensively and thoroughly elaborates on the clinical features, diagnostic criteria, influencing factors, and new ideas of acute demyelinating diseases of the central nervous system in children. These become more operable in clinical diagnosis and treatment of multiple sclerosis and other immune-mediated demyelinating diseases of the central nervous system in children.

<p><b>OBJECTIVE</b>To explore the effect of total flavonoids of Herba Epimedium (FHE) on BMP-2/RunX2/OSX signaling pathway in promoting osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs).</p><p><b>METHODS</b>Passage 3 BMSCs were randomly divided into the control group, the experimental group, and the inhibitor group. BMSCs in the control group were cultured in 0.2% dimethyl sulfoxide + Osteogenuxic Supplement (OS) fluid + DMEM/F12 culture media. BMSCs in the experimental group were intervened by 20 microg/mL FHE. BMSCs in the inhibitor group were intervened by 20 microg/mL FHE and 1 microg/mL NOGGIN recombinant protein. At day 9 alkaline phosphatase (ALP) activity was measured. Calcium nodules were stained by alizarin red staining and the density was observed. The transcription expression of osteogenic differentiation-related proteins (type I collagen, osteocalcin, and osteopontin) and related factors of BMP-2/RunX2/OSX signaling pathway was assayed by RT-PCR.</p><p><b>RESULTS</b>Compared with the control group, ALP activities were enhanced and the density of calcium nodules significantly increased; type I collagen, osteocalcin, and osteopontin expression levels were increased in the experimental group. The expression of osteogenesis-related transcription factor was also increased in the experimental group. Noggin recombinant protein inhibited FHE promoting BMSCs osteogenesis in the inhibitor group. Compared with the experimental group, ALP activity decreased (P < 0.05), the density of calcium nodules was lowered, expression levels of type I collagen, osteocalcin, osteopontin significantly decreased (P < 0.05) in the inhibitor group.</p><p><b>CONCLUSION</b>20 microg/mL FHE promoted osteogenic differentiation process of BMSCs by BMP-2/RunX2/OSX signaling pathway.</p>

ABSTRACT

<p><b>OBJECTIVE</b>This study explored the correlation of longitudinal changes in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels with the incidence of metabolic syndrome (Mets) based on a dynamic health examination cohort.</p><p><b>METHODS</b>A Mets-free dynamic cohort involving 4541 participants who underwent at least three health examinations from 2006 to 2011 was included in the study. Mets was defined according to the Chinese Medical Association Diabetes Branch definition that included hypertension, obesity, hyperlipidemia, and hyperglycemia. Generalized estimating equation (GEE) model was used to analyze multivariate relative risk (RR) of repeated observations of ALT and AST in quartiles for Mets or its components according to gender.</p><p><b>RESULTS</b>In all, 826 Mets cases were reported. Adjustment of relevant parameters indicated that time-varying changes in ALT and AST levels were positively associated with the incidence of Mets in a dose-response manner. Positive association between high ALT levels and fatty liver was much stronger than that between high AST levels and fatty liver, particularly in male participants. These associations were consistently observed in the following subgroups: participants with ALT and AST levels of <40 U/L, participants with of <25 kg/m2, and participants with non-fatty liver. Furthermore, participants with 2 Mets components at baseline showed lower multivariate adjusted RRs of ALT and AST for Mets than participants with 0-1 Mets component.</p><p><b>CONCLUSION</b>These results suggested that elevated serum ALT and AST levels were early biomarkers of Mets or its components.</p>
