RÉSUMÉ

Soybean and derived products are among the most important food for both humans and animals. China is the world's largest importer of soybeans, with more than 100 million tons of annual imports, mainly from the United States of America (US), Brazil, and Argentina. However, there have been limited studies on the microbiota associated with imported soybean grains. Here, we reveal the soybean microbiota using amplicon sequencing based on samples from four countries on three continents of North America (US), South America (Argentina, Brazil), and Asia (China). Our results showed that the soybean-associated microbiota from different continents significantly separated, presenting strong geographic variations. The core microbial taxa and geographically specified taxa were defined, with Alternaria, Enterobacter, Plectosphaerella, Stenotrophomanas, and Xeromyces defined as the core microbiota for soybean from Asia; Amanita, Aspergillus, Fusarium, Nigrospora, Herbiconiux, Pseudomonas, Saccharopolyspora, and Schumannella from North America; and Bradyrhizobium, Colletotrichum, Filobasidium, Phialosimplex, Mycosphaerella, Septoria, Sphingomonas, and Weissalla, from South America. In addition, we build the Random Forest (RF) model to predict the source of imported soybean grains. We could accurately predict the original countries of imported soybean grains within the RF prediction models, with accuracies greater than 95 %. We constructed a database of soybean-related quarantine pathogens using full-length sequences of fungal ITS region and bacterial 16S rDNA region. Two phytopathogenic fungi, Diaporthe caulivora and Cladosporium cucumerinum, listed in the Chinese quarantine catalog, were intercepted through metabarcoding sequencing. The former was further confirmed using an available national standard protocol of qPCR diagnosis. In summary, our NGS-based approach revealed the microbiota associated with soybeans. It could provide comprehensive information and valuable method on the trace the origin of soybean and detection of quarantine pathogens at Customs and departments of inspection and quarantine.

RÉSUMÉ

Disturbance of commensal intestinal microbiota is related to chronic inflammatory dermatosis. We analyzed the diversity of the gut microbiota to characterize the biological variation of psoriasis (Ps). Significant differences of gut microbiome profiles were revealed in murine model with psoriasis by sequencing 16S rRNA V3-V4 variable region. Group comparisons included the imiquimod cream (IMQ group, n=8), the imiquimod cream and antibiotics (ATB) (PC+IMQ group, n=8) and the healthy control (CTRL group, n=8). The gut microbiota existed in Ps groups including IMQ group and PC+IMQ group encompassed less diversity than controls, which were attributed to decreased presence of several taxa. The two Ps groups were characterized by significant reduction in firmicutes. In this study, microbiota of psoriasis was defined by an increase presence of Bacteroides. After treated with ATB, we found substantial increase of Lactobacillales but significant decrease of Clostridiales and Coriobacteriales. Relative lower abundance of multiple intestinal bacteria was observed in Ps groups. Although part of genera were concomitantly reduced in both IMQ and PC+IMQ conditions, we discovered the specialty of PC+IMQ group samples was that contained lower abundance of beneficial taxa. Characteristics of gut microbiota profiles in Ps mice were comparable to profiles in patients with Ps, which were related to alteration of specific inflammatory proteins in disease groups but were significantly different from control group. Thus, this study emphasizes the role of intestinal microbiota in the pathogenesis of Ps and provides new insight for investigating association between intestinal microbes and immune inflammation.


A perturbação da microbiota intestinal comensal está relacionada à dermatose inflamatória crônica. Analisamos a diversidade da microbiota intestinal para caracterizar a variação biológica da psoríase (Ps). Diferenças significativas do perfil microbiológico intestinal foram reveladas no modelo murino com psoríase pelo sequenciamento da região variável 16S rRNA V3-V4. As comparações de grupo incluíram o creme imiquimod (grupo IMQ, n=8), o creme imiquimod e antibióticos (ATB) (grupo PC+IMQ, n=8) e o controle saudável (grupo CTRL, n=8). A microbiota intestinal existia nos grupos Ps, incluindo o grupo IMQ e o grupo PC+IMQ englobava menos diversidade do que os controles, que foram atribuídos à diminuição da presença de vários taxa. Os dois grupos de Ps caracterizavam-se por uma redução significativa nos firicutes. Neste estudo, a microbiota da psoríase foi definida por um aumento da presença de bacteroides. Após o tratamento com ATB, encontramos um aumento substancial de Lactobacillales mas uma diminuição significativa de Clostridiales e Coriobacteriales. Uma menor abundância relativa de bactérias intestinais múltiplas foi observada nos grupos de Ps. Embora parte dos gêneros tenha sido concomitantemente reduzida tanto em condições IMQ como PC+IMQ, descobrimos que a especialidade das amostras do grupo PC+IMQ era que continham menor abundância de taxas benéficas. As características dos perfis de microbiota intestinal em ratos de Ps eram comparáveis aos perfis em pacientes com Ps, que estavam relacionados à alteração de proteínas inflamatórias específicas em grupos de doenças, mas eram significativamente diferentes do grupo controle. Assim, este estudo enfatiza o papel da microbiota intestinal na patogênese do Ps e fornece novos conhecimentos para investigar a associação entre micróbios intestinais e inflamação imunológica.

RÉSUMÉ

Two series of novel 4-phenoxypyridine derivatives containing imidazole-4-carboxamide and 4-methyl-5-oxo-4,5-dihydro-1,2,4-triazole-3-carboxamide moieties were synthesized and evaluated for their in vitro inhibitory activities against c-Met kinase and antiproliferative activities against MKN-45, A549 and H460 cancer cell lines. The results indicated that most of the compounds showed moderate to good antitumor activities. The most promising compound T14 (with c-Met IC50 value of 0.012 µM) showed remarkable antiproliferative activities against MKN-45, A549 and H460 cell lines with IC50 values of 0.64 µM, 1.92 µM and 2.68 µM, respectively. Their preliminary structure-activity relationships (SARs) studies indicate that imidazole-4-carboxamide was more preferred as linker part, and electron-withdrawing groups (especially halogen groups) on the terminal phenyl rings were beneficial for improving the antitumor activities.

RÉSUMÉ

Influenza viruses exacerbate chronic obstructive pulmonary disease (COPD) with considerable morbidity and mortality. Zanamivir and oseltamivir are effective in treating influenza. However, their efficacy in relieving influenza symptoms in COPD patients remains unknown, with the lack of controlled trials in this subject. Therefore, we conducted this randomized controlled trial to investigate the clinical efficacy of both interventions in this population. Patients were allocated to two groups (80 patients each): oseltamivir (OSELTA) and zanamivir (ZANA) groups. Oseltamivir (75 mg) was orally administered twice daily for 5 days, while zanamivir (10 mg) was inhaled twice daily for 5 days. Clinical parameters including body temperature, influenza symptoms (i.e., sore throat, cough, etc.), and serial blood tests were recorded on days 1, 3, and 7. We analyzed primary (changes in body temperature) and secondary outcomes (changes in non-specific symptoms) using the pre-protocol and intention-to-treat analyses. Differences between groups were assessed using t-test. Oseltamivir and zanamivir significantly reduced body temperature on the 3rd day after treatment; however, the number of patients who reported clinical improvement in influenza-like symptoms was significantly higher in the OSELTA group compared to the ZANA group on days 3 (85 vs 68.8%, P=0.015) and 7 (97.5 vs 83.8%, P=0.003). However, no significant changes in hematological (white blood cells and its subtypes) and inflammatory (C-reactive protein) parameters were noted (P>0.05). Our results suggested that oseltamivir and zanamivir are effective in reducing body temperature, while oseltamivir led to better clinical improvement regarding influenza-like symptoms in patients with COPD.

RÉSUMÉ

Despite extensive studies on the gastric microbiota, including Helicobacter pylori and non-H. pylori, the bacterial composition in children remains unknown. In this study, we analyzed the culturable gastric bacteria in stomach biopsies from 346 children aged 1-15 years affected by gastric diseases. H. pylori and non-H. pylori were identified by specific PCR and 16S rDNA sequencing, respectively. Antibiotic susceptibilities of H. pylori and non-H. pylori were tested by the E-test and disk diffusion methods, respectively. Rapid diagnosis was also performed by H. pylori-specific PCR. Twenty-two H. pylori strains were obtained from culture, and 92 biopsies were positive by H. pylori-specific PCR. The positive rate was higher in boys (40.3%) than in girls (23.3%) (P = 0.001). Resistance rates of 22 H. pylori strains were as follows: metronidazole, 86.4%; tetracycline, 22.7%; amoxicillin, 22.7%; levofloxacin, 31.8%; clarithromycin, 36.4%. Ten isolates were multidrug-resistant. Additionally, among 366 non-H. pylori strains, 204 exhibited urease activity. Non-H. pylori resistance rates were as follows: metronidazole, 94.8%; tetracycline, 26.2%; amoxicillin, 42.6%; levofloxacin, 15.3%; clarithromycin, 46.7%. Our results showed that children with gastric disorders harbor stomach bacteria with urease activity or nitrate reductase activity. Further studies will determine the effects of non-H. pylori bacteria in gastric diseases.

RÉSUMÉ

OBJECTIVE: To investigate the prevalence of congenital heart disease (CHD) in China based on a large prospective multicenter screening study. STUDY DESIGN: A total of 122 765 consecutive infants born at 18 hospitals throughout China between August 1, 2011, and November 30, 2012, were included. Cases of CHD were identified by echocardiography, clinical assessment, and telephone follow-up. RESULTS: The overall prevalence of CHD was 8.98 per 1000 live births (critical, 1.46; serious, 1.47; significant, 5.00; nonsignificant, 1.07), including 7.15 in male infants and 11.11 in female infants. The most common CHD was ventricular septal defect (3.3), followed by atrial septal defect (1.7), patent ductus arteriosus (0.78), pulmonary stenosis (0.73), tetralogy of Fallot (0.47), and transposition of the great arteries (0.35). Female predominance was observed for all CHD and mild CHD (significant and nonsignificant), and male predominance was observed for the critical CHDs. The proportion of preterm newborns was substantially higher among the major CHD cases (critical and serious) compared with normal newborns. There were appreciably more low birth weight infants among the critical CHD cases compared with normal newborns. Significantly higher rates of ventricular septal defect and atrioventricular septal defect were found in infants born to mothers aged ≥35 years. Extracardiac anomalies were found in 9.3% of CHD cases. The risk of CHD was increased by approximately 3-fold when a first-degree relative had CHD. CONCLUSIONS: Our estimates are concordant with data from Western studies. This screening study may provide more accurate and complete information on the overall prevalence of CHD in China.

RÉSUMÉ

Background: Although the functional redundancy of catechol 1,2-dioxygenase (C12O) genes has been reported in several microorganisms, limited enzymes were characterised, let alone the advantage of the coexistence of the multiple copies of C12O genes. Results: In this study, four novel C12O genes, designated catA, catAI, catAII and catAIII, in the naphthalene-degrading strain Pseudomonas putida ND6, were cloned and characterised. Phylogenetic analysis of their deduced amino acid sequences revealed that the four C12O isozymes each formed independent subtrees, together with homologues from other organisms. All four enzymes exhibited maximum activity at pH 7.4 and higher activity in alkaline than in acidic conditions. Furthermore, CatA, CatAI and CatAIII were maximally active at a temperature of 45°C, whereas a higher optimum temperature was observed for CatAII at a temperature of 50°C. CatAI exhibited superior temperature stability compared with the other three C12O isozymes, and kinetic analysis indicated similar enzyme activities for CatA, CatAI and CatAII, whereas that of CatAIII was lower. Significantly, among metal ions tested, only Cu2+ substantially inhibited the activity of these C12O isozymes, thus indicating that they have potential to facilitate bioremediation in environments polluted with aromatics in the presence of metals. Moreover, gene expression analysis at the mRNA level and determination of enzyme activity clearly indicated that the redundancy of the catA genes has increased the levels of C12O. Conclusion: The results clearly imply that the redundancy of catA genes increases the available amount of C12O in P. putida ND6, which would be beneficial for survival in challenging environments.

RÉSUMÉ

We report a 12-year-old girl who presented with recurrent angioedema on the face, trunk, and extremities, and concomitant marked weight gain for 5 years. During the episode, her white blood cell count increased to 47.7×109/L with 89.9% eosinophils, followed by elevated serum level of IL-5, IgE, IgM, and LDH. Histopathology showed perivascular eosinophilic infiltration and diffuse eosinophilic infiltration throughout the dermis. Possible causes of hypereosinophilia and eosinophilic infiltration of vital organs were ruled out. We also tested the FIP1L1/PDGFRa and ETV6/PDGFRb fusion gene to exclude the possibility of myeloid and lymphatic vessel neoplasms. The patient was treated with methylprednisolone and discharged with an oral prednisolone taper, which resulted in complete remission of the edema and normalization of peripheral blood eosinophil count, serum IL-5 level, IgE, IgM, and LDH.

RÉSUMÉ

The introduction of allosteric receptor-receptor interactions in G protein-coupled receptor (GPCR) heteroreceptor complexes of the central nervous system (CNS) gave a new dimension to brain integration and neuropsychopharmacology. The molecular basis of learning and memory was proposed to be based on the reorganization of the homo- and heteroreceptor complexes in the postjunctional membrane of synapses. Long-term memory may be created by the transformation of parts of the heteroreceptor complexes into unique transcription factors which can lead to the formation of specific adapter proteins. The observation of the GPCR heterodimer network (GPCR-HetNet) indicated that the allosteric receptor-receptor interactions dramatically increase GPCR diversity and biased recognition and signaling leading to enhanced specificity in signaling. Dysfunction of the GPCR heteroreceptor complexes can lead to brain disease. The findings of serotonin (5-HT) hetero and isoreceptor complexes in the brain over the last decade give new targets for drug development in major depression. Neuromodulation of neuronal networks in depression via 5-HT, galanin peptides and zinc involve a number of GPCR heteroreceptor complexes in the raphe-hippocampal system: GalR1-5-HT1A, GalR1-5-HT1A-GPR39, GalR1-GalR2, and putative GalR1-GalR2-5-HT1A heteroreceptor complexes. The 5-HT1A receptor protomer remains a receptor enhancing antidepressant actions through its participation in hetero- and homoreceptor complexes listed above in balance with each other. In depression, neuromodulation of neuronal networks in the raphe-hippocampal system and the cortical regions via 5-HT and fibroblast growth factor 2 involves either FGFR1-5-HT1A heteroreceptor complexes or the 5-HT isoreceptor complexes such as 5-HT1A-5-HT7 and 5-HT1A-5-HT2A. Neuromodulation of neuronal networks in cocaine use disorder via dopamine (DA) and adenosine signals involve A2AR-D2R and A2AR-D2R-Sigma1R heteroreceptor complexes in the dorsal and ventral striatum. The excitatory modulation by A2AR agonists of the ventral striato-pallidal GABA anti-reward system via targeting the A2AR-D2R and A2AR-D2R-Sigma1R heteroreceptor complex holds high promise as a new way to treat cocaine use disorders. Neuromodulation of neuronal networks in schizophrenia via DA, adenosine, glutamate, 5-HT and neurotensin peptides and oxytocin, involving A2AR-D2R, D2R-NMDAR, A2AR-D2R-mGluR5, D2R-5-HT2A and D2R-oxytocinR heteroreceptor complexes opens up a new world of D2R protomer targets in the listed heterocomplexes for treatment of positive, negative and cognitive symptoms of schizophrenia.

RÉSUMÉ

We report an imported case of cutaneous leishmaniasis in a 37-year-old man from Saudi Arabia caused by Leishmania major. He presented with non-healing nodulo-ulcerative lesions with a "volcanic crater" on the lower limbs. It was clearly cutaneous leishmaniasis - a rare disease in China - as reflected by the patient's clinical history, the lesions' morphology, histopathological examination, culture and PCR analysis of the lesions. The patient was completely cured after two cycles of sodium stibogluconate treatment. This case report demonstrates that dermatologists should be aware of sporadic cutaneous leishmaniasis cases in non-endemic areas.

RÉSUMÉ

ABSTRACTThe aim of this work was to study the co-production of nattokinase and poly (γ-glutamic acid) by Bacillus subtilis natto with soybean and rice husk under solid-state fermentation (SSF). The results showed that the size of soybean particle and rice husk significantly improved the co-production of nattokinase and poly (γ-glutamic acid), yielding 2503.4 IU/gs and 320 mg/gs, respectively in the improved culture medium composed of 16.7% soybean flour and 13.3% rice husk with 70% water content. The yields increased by approximate 7- and 2-fold factor relative to their original ones. Thus, the co-production of nattokinase and poly (γ-glutamic acid) under SSF could be considered as an efficient method to exploit agro-residues for economical production of some higher-value products.

RÉSUMÉ

Malignant atrophic papulosisis is a rare, multisystem obliterative vasculopathy of unknown etiology, occasionally involving the cranial nerve. We describe the first case of malignant atrophic papulosisis with cranial nerve and peripheral nerve involvement in China. A 47-year-old woman presented to our hospital with atrophic porcelain white papules over the trunk and extremities, numbness in the right calf, vision decrease and impaired movement of the right eye. She was diagnosed with malignant atrophic papulosisis, based on characteristic symptoms and histopathologic examination. The patient was treated with dipyridamole and aspirin for 9 months, but later died of gastrointestinal hemorrhage. We reviewed currently available case reports on cranial nerve involvement in malignant atrophic papulosisis and emphasized the importance of skin biopsy in diagnosing this disease.

RÉSUMÉ

Methotrexate has been widely used for many years in the treatment of a variety of diseases. Acute pneumonitis and bone marrow suppression are very serious side effects in methotrexate treatment. A 48-year-old man with end-stage renal disease undergoing chronic hemodialysis developed combined acute pneumonitis and pancytopenia after a cumulative dose of 20 mg methotrexate for bullous pemphigoid. Continuous renal replacement therapy (CRRT) can efficiently decrease serum methotrexate concentration. A rapid improvement of clinical symptoms and resolution of pulmonary opacification were found after CRRT. Blood cell counts returned to normal after component blood transfusion and cytokine supportive therapy. Patients with impaired renal function are at high risk of methotrexate toxicity, and low-dose methotrexate should be prescribed with great caution.

RÉSUMÉ

We report the case of a 38-year-old man, who developed cutaneous metastases in the left inguinal groove 15 years after curative gastrectomy for advanced gastric adenocarcinoma. Histopathologic examination revealed poorly differentiated adenocarcinoma cells. They were stained positive for villin, CDX-2, CKpan (AE1/ AE3), CEA, CK8/18, CK19, CK7, EMA, Ki-67 (50%), and negative for S-100, CK20, CD34, GCDFP-15 and TTF-1. The patient underwent local excision, after the presence of other metastases was excluded. Nevertheless, local recurrence developed at the surgical bed one year later and PET/CT revealed metastases to lymph nodes, bone and skin. He died 2 years after the appearance of cutaneous metastases.

RÉSUMÉ

Abstract

Methotrexate has been widely used for many years in the treatment of a variety of diseases. Acute pneumonitis and bone marrow suppression are very serious side effects in methotrexate treatment. A 48-year-old man with end-stage renal disease undergoing chronic hemodialysis developed combined acute pneumonitis and pancytopenia after a cumulative dose of 20 mg methotrexate for bullous pemphigoid. Continuous renal replacement therapy (CRRT) can effi ciently decrease serum methotrexate concentration. A rapid improvement of clinical symptoms and resolution of pulmonary opacifi cation were found after CRRT. Blood cell counts returned to normal after component blood transfusion and cytokine supportive therapy. Patients with impaired renal function are at high risk of methotrexate toxicity, and low-dose methotrexate should be prescribed with great caution.

RÉSUMÉ

Abstract

Malignant atrophic papulosisis is a rare, multisystem obliterative vasculopathy of unknown etiology, occasionally involving the cranial nerve. We describe the first case of malignant atrophic papulosisis with cranial nerve and peripheral nerve involvement in China. A 47-year-old woman presented to our hospital with atrophic porcelain white papules over the trunk and extremities, numbness in the right calf, vision decrease and impaired movement of the right eye. She was diagnosed with malignant atrophic papulosisis, based on characteristic symptoms and histopathologic examination. The patient was treated with dipyridamole and aspirin for 9 months, but later died of gastrointestinal hemorrhage. We reviewed currently available case reports on cranial nerve involvement in malignant atrophic papulosisis and emphasized the importance of skin biopsy in diagnosing this disease.

RÉSUMÉ

Abstract

We report the case of a 38-year-old man, who developed cutaneous metastases in the left inguinal groove 15 years after curative gastrectomy for advanced gastric adenocarcinoma. Histopathologic examination revealed poorly differentiated adenocarcinoma cells. They were stained positive for villin, CDX-2, CKpan (AE1/ AE3), CEA, CK8/18, CK19, CK7, EMA, Ki-67 (50%), and negative for S-100, CK20, CD34, GCDFP-15 and TTF-1. The patient underwent local excision, after the presence of other metastases was excluded. Nevertheless, local recurrence developed at the surgical bed one year later and PET/CT revealed metastases to lymph nodes, bone and skin. He died 2 years after the appearance of cutaneous metastases. We have reviewed the literature and described the immunohistochemical characteristics of cutaneous metastases from gastric adenocarcinoma.
