ABSTRACT A March male Golden, weighing 7.6kg, presented with gradual weight loss, high body temperature, depression, poor appetite and thirst, and vomiting before consultation. The results showed that the erythrocytes, hematocrit, hemoglobin, and platelets were lower than the reference values. The diagnosis of mixed infection with haematocrit and eosinophilic bodies was confirmed by real-time fluorescence PCR of whole blood, which was positive for haematocrit and eosinophilic bodies. The dog was treated with doxycycline and ceftriaxone, and the dog fully recovered after 2 weeks with blood transfusion, symptomatic treatment, and supportive therapy. This indicates that the disease can be treated well by a comprehensive treatment approach.

ABSTRACT BACKGROUND: Computer-aided diagnosis in low-dose (≤ 3 mSv) computed tomography (CT) is a potential screening tool for lung nodules, with quality interpretation and less inter-observer variability among readers. Therefore, we aimed to determine the screening potential of CT using a radiation dose that does not exceed 2 mSv. OBJECTIVE: We aimed to compare the diagnostic parameters of low-dose (< 2 mSv) CT interpretation results using a computer-aided diagnosis system for lung cancer screening with those of a conventional reading system used by radiologists. DESIGN AND SETTING: We conducted a comparative study of chest CT images for lung cancer screening at three private institutions. METHODS: A database of low-dose (< 2 mSv) chest CT images of patients at risk of lung cancer was viewed with the conventional reading system (301 patients and 226 nodules) or computer-aided diagnosis system without any subsequent radiologist review (944 patients and 1,048 nodules). RESULTS: The numbers of detected and solid nodules per patient (both P < 0.0001) were higher using the computer-aided diagnosis system than those using the conventional reading system. The nodule size was reported as the maximum size in any plane in the computer-aided diagnosis system. Higher numbers of patients (102 [11%] versus 20 [7%], P = 0.0345) and nodules (154 [15%] versus 17 [8%], P = 0.0035) were diagnosed with cancer using the computer-aided diagnosis system. CONCLUSIONS: The computer-aided diagnosis system facilitates the diagnosis of cancerous nodules, especially solid nodules, in low-dose (< 2 mSv) CT among patients at risk for lung cancer.

RESUMO Introdução O biatlo é um esporte de neve que combina esqui entre as montanhas e tiro, originário da Escandinávia. Requer que os atletas não só tenham a capacidade de deslizar rapidamente por longas distâncias, mas também que tenham a capacidade de atirar com rapidez e precisão. Existem poucas pesquisas sobre características do biatlo e análises de fatores de influência e estratégias de treinamento na China. Objetivo Este estudo analisa o poder explosivo específico, a resistência e os efeitos do treinamento dos atletas modernos de biatlo nos Jogos Olímpicos de Inverno. Métodos Selecionou-se 20 atletas de biatlo como voluntários de pesquisa. Os indicadores fisiológicos e bioquímicos dos atletas foram testados experimentalmente após o treinamento. Resultados Houve uma correlação entre a velocidade máxima e a altura do teste de duplo suporte (DP) dos atletas (p < 0,05). Os atletas mais pesados esquiam relativamente mais rápido. Porém a taxa excessiva de gordura corporal não é propícia para manter o esqui de alta intensidade a longo prazo. O VO2max dos atletas mostrou-se intimamente relacionado com seu desempenho de esqui e porcentagem de acertos no tiro (p < 0,05). Conclusão A manutenção do treinamento de esqui com armas pode desempenhar um papel positivo na melhoria do nível competitivo dos biatletas de classe mundial.

ABSTRACT Introduction The biathlon is a snow sport that combines cross-country skiing and shooting, originating in Scandinavia. It requires athletes to not only have the ability to glide quickly over long distances but also to have the ability to shoot quickly and accurately. There is little research on biathlon characteristics and analysis of influencing factors and training strategies in China. Objective This study analyzes modern biathlon athletes’ specific explosive power, endurance and training effects at the Winter Olympics. Methods Twenty biathlon athletes were selected as research volunteers. Physiological and biochemical indicators of the athletes were experimentally tested after training. Results There was a correlation between maximum speed and the height of the athletes’ double stand test (SD) (p < 0.05). The heavier athletes skied relatively faster. However, the excessive body fat rate is not conducive to maintaining high-intensity skiing in the long term. The athletes’ VO2max was closely related to their skiing performance and shot hit percentage (p < 0.05). Conclusion Maintaining gun ski training can positively improve the competitive level of world-class biathletes. The athlete's muscles have a solid ability to generate high mechanical power in a short time. It is beneficial to take advantage of a favorable position after the start of the competition. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Abstract Objective: To analyze the value of serum miRNA-122 expression in the diagnosis, severity, and prognosis of Acute Cerebral Infarction (ACI) and the correlation mechanism of serum miRNA-122 on the proliferation and apoptosis of vascular endothelial cells in ACI. Method: A total of 60 patients with ACI who were admitted to the emergency department of the Taizhou People’s Hospital from January 1, 2019, to December 30, 2019, and 30 healthy controls during the same period were selected. General clinical data of all patients at admission were collected. Including age, sex, medical history, and inflammatory factors (C-Reactive Protein [CRP], Interleukin-6 [IL-6], Procalcitonin [PCT], Neutrophil Gelatinase-Associated Lipid carrier protein [NGAL]). The National Institutes of Health Stroke Scale (NIHSS) score at admission and short-term prognosis (the Modified Rankin Score [mRS]) score at 3 months after onset were recorded. The expression level of miRNA-122 in the serum of patients with ACI and normal controls was detected by reverse-transcription quantitative Real-Time Polymerase Chain Reaction (RT-QPCR), and the correlation between the expression level of miRNA-122 in the serum of patients with ACI and the level of inflammatory factors, NIHSS and mRS scores were analyzed. The expression levels of miRNA-122 in the serum of patients with ACI, normal people, and Human Umbilical cord Endothelial Cells (HUVECs) cultured in a blank control group were detected by RT-QPCR and statistically analyzed. MTT and flow cytometry was used to compare the proliferation and apoptosis of vascular endothelial cells in the miRNA-122 mimics and inhibitors transfection groups and the corresponding negative control group. The mRNA and protein levels of apoptosis-related factors Bax, Bcl-2, Caspase-3, and angiogenesis-related proteins Hes1, Notch1, Vascular Endothelial Growth Factors (VEGF), and CCNG1 were detected by RT-QPCR and Western blot. Bioinformatics methods predicted CCNG1 to be the target of miRNA-122, and the direct targeting relationship between CCNG1 and miRNA-122 was verified by a dual-luciferase reporting assay. Result: Serum miRNA-122 expression in patients with ACI was significantly higher than that in healthy controls, with an area under the receiver operating characteristic curve of 0.929, 95% Confidence Interval of 0.875‒0.983, and an optimal cut-off value of 1.397. The expression levels of CRP, IL-6, and NGAL in patients with ACI were higher than those in healthy control groups, p < 0.05; miRNA-122 was positively correlated with CPR, IL-6, NIHSS score, and mRS score. At 48h and 72h, the proliferation rate of HUVECs cells in the miRNA-122 mimics group decreased and the apoptosis rate increased. Cell proliferation rate increased, and apoptosis rate decreased significantly in the groups transfected with miRNA-122 inhibitors. The mRNA and protein levels of pro-apoptotic factors Bax and caspase-3 were significantly increased in the miRNA-122 mimics transfection group, while those of anti-apoptotic factor Bcl-2 were significantly decreased compared to those of the control group. The expression of Bax and Caspase-3 decreased, and the expression of anti-apoptotic factor Bcl-2 increased in the transfected miRNA-122 inhibitors group. mRNA expression levels of Hes1, Notch1, VEGF, and CCNG1 in the miRNA-122 mimic transfected group were significantly decreased, while mRNA expression levels in the miRNA-122 inhibitors transfected group were significantly increased. Bioinformatics showed that there was a miRNA-122 binding site in the 3′UTR region of CCNG1, and dual luciferase assay confirmed that CCNG1 was the target of miRNA-122.

Early and accurate diagnosis of acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation is crucial for the prognosis of patients. This study identified a potential biomarker for the severity of aGVHD after human leukocyte antigen (HLA)-haploidentical peripheral blood hematopoietic stem cell transplantation (haplo-PBSCT). We included 20 healthy subjects and 57 patients who underwent haplo-PBSCT. Of these patients, 22 developed aGVHD after haplo-PBSCT. The results showed that patients with aGVHD had significantly increased levels of Tim-3+/Perforin+/Granzyme B+CD8+ T cells, but significantly decreased Galectin-9. The differences in Galectin-9 and Tim-3+/Granzyme B+CD8+ T cells between grade I-II aGVHD and III-IV aGVHD were also significant. In vitro, the apoptosis of CD8+ T cells from aGVHD patients was significantly increased after Tim-3/Galectin-9 pathway activation, which decreased Granzyme B secretion. As revealed by univariate analysis, the level of Tim-3+CD8+ T cells was a risk factor for severe aGVHD. ROC analysis demonstrated that high levels of Tim-3+CD8+ T cells had a significant diagnostic value for severe aGVHD, with an area under the curve of 0.854 and cut-off value of 14.155%. In conclusion, the binding of Tim-3 with exogenous Galectin-9 can promote apoptosis of CD8+ T cells and affect the secretion of Granzyme B. Tim-3+CD8+ T cells have the potential to serve as immunological markers for assessing the severity of aGVHD after haplo-PBSCT and identifying patients at a higher risk for severe aGVHD.

ABSTRACT Cereal cyst nematode is a major pest of small grain cereals, which causes huge yield losses to crops in China and other parts of the world. In this study, the effects of five inorganic ion concentrations on egg hatching of Heterodera avenae were studied. Results revealed that ZnCl2 and FeCl3 promoted hatching of induced and natural diapausing eggs. The cumulative hatching rates of eggs were 49 % and 13 % at 30 mM ZnCl2 and 10 mM FeCl3, respectively, which were higher than those of other treatments. The hatching ability promoted by ZnCl2 is greater than by FeCl3. Diapause induced eggs in ZnCl2 continued to hatch after 10 days; however, those in FeCl3 mainly hatched in the first two weeks. ZnCl2 had obvious stimulating effects on the hatching of natural diapause and non–diapause free eggs at 15 and 30 mM concentrations. FeCl3 promoted the hatching of natural diapause eggs; howevr, it inhibited hatching of non–diapause free eggs. Conversely, different concentrations of inorganic ions did not have any stimulatory effect on white female eggs. In the nematode life cycle, hatching is the critical stage because juveniles may be infected. The results of this study provide useful information the use of new fertilizers (including promoted hatching inorganic ions) applied before planting for controlling nematode diseases caused by H. avenae.

Resumo: Governança significa a política e a estratégia adotadas no processo de gestão de um país. Na longa história de mais de dois mil anos, o confucionismo tornou-se o núcleo cultural e a doutrina política da autocracia imperial, e a teoria da “governança de todo o país” contida nele tornou-se uma categoria importante na cultura tradicional chinesa. Deve-se aprofundar na rica conotação do pensamento de governança confucionista e construir um sistema de governança nacional que se adapte à sociedade, à situação geral e ao futuro, por meio de desenvolvimento inovador e transformação criativa, de modo a permitir que a excelente cultura tradicional chinesa retorne à base, para abrir um novo caminho e fazer o passado servir ao presente, fornecendo, assim, importante orientação teórica e referência histórica para o grande rejuvenescimento da nação chinesa.

Abstract: Governance means the policy and strategy adopted in the process of running a country. In the long history of more than two thousand years, Confucianism had become the cultural core and political doctrine of the imperial autocracy, and the theory of “governance of the whole country” contained in it had become an important category in traditional Chinese culture. We should dig deep into the rich connotation of Confucian governance thought, and build a national governance system that suits society, the overall situation and future through innovative development and creative transformation, so as to let excellent traditional Chinese culture return to open a new road and make the past serve the present, thus providing important theoretical guidance and historical reference for the great rejuvenation of the Chinese nation.

Abstract Serrapeptase, a proteolytic enzyme, has been used for the adjuvant treatment of many diseases. However, its fibrinolytic activity is still uncertain. Herein, the fibrinolytic activity of serrapeptase and its in vitro thrombolytic effects were investigated. The results showed that the fibrinolytic activity of serrapeptase was 1295 U/mg, and the specific activity was 3867 U/mg of protein when its proteolytic activity toward casein was 2800 U/mg. The optimum temperature and pH for serrapeptase activity were 37-40°C and 9.0, respectively. At 1 mmol/L, Zn2+, Mn2+ and Fe2+ could activate the fibrinolytic activity of serrapeptase, while K+, Cu2+, sodium dodecyl sulfate (SDS) and ethylene diamine tetraacetic acid (EDTA) inhibited it. In vitro tests showed that serrapeptase could completely prevent blood coagulation at 150 U/mL, and the percentage of blood clot lysis reached 96.6% at 37°C after 4 h at 300 U/mL. These results indicate that serrapeptase has excellent fibrinolytic activity, and can be used as a health food or candidate drug for the prevention or treatment of thrombotic diseases.

CONCLUSIONS: The computer-aided diagnosis system facilitates the diagnosis of cancerous nodules, especially solid nodules, in low-dose (< 2 mSv) CT among patients at risk for lung cancer.

Abstract Introduction Allergic rhinitis is a form of IgE mediated inflammation of the nasal mucosa in response to specific allergens, resulting in typical symptoms. Objectives This study was designed with the primary goal of comparing the clinical efficacy of posterior nasal neurectomy with or without pharyngeal neurectomy for the treatment of moderate-to-severe perennial allergic rhinitis. Secondary study aims included a comparison of the severity of comorbidities, including chronic cough and asthma, between patients in these two surgical treatment groups. Methods A total of 52 patients were enrolled in this randomized controlled trial and were assigned to either the control group (posterior nasal neurectomy) or the experimental group (posterior nasal neurectomy + pharyngeal neurectomy). The visual analog scale and rhinoconjunctivitis quality of life questionnaire were used to compare the differences in patient symptoms between baseline and 6-, 12-, and 24-months post-treatment. In addition, patient cough and asthma symptoms were monitored during follow-up via visual analog scale and asthma control test respectively. Results No significant differences in preoperative scores were evident between groups (p> 0.05). At 6-months post-treatment, there were significant differences in visual analog scale, rhinoconjunctivitis quality of life questionnaire, and asthma control test scores relative to baseline values in experimental group and control group patients (p< 0.05), and this remained true upon 12- and 24-month follow-up. No significant differences in visual analog scale, rhinoconjunctivitis quality of life questionnaire, or asthma control test scores were observed between the two treatment groups at any postoperative follow-up time point (p> 0.05), while coughing severity was found to be significantly reduced in the experimental group relative to the control group (p< 0.05). Conclusion posterior nasal neurectomy can be safely implemented with or without pharyngeal neurectomy in order to effectively treat allergic rhinitis. Combined posterior nasal neurectomy and pharyngeal neurectomy treatment may offer greater value than posterior nasal neurectomy alone for the treatment of allergic rhinitis patients with chronic cough.

Resumo Introdução A rinite alérgica é uma forma de inflamação da mucosa nasal mediada por IgE em resposta a alérgenos específicos, resulta em sintomas típicos. Objetivos Comparar a eficácia clínica da neurectomia nasal posterior com ou sem neurectomia faríngea para o tratamento da rinite alérgica perene de moderada a grave. Além disso, comparar a gravidade das comorbidades, inclusive tosse crônica e asma, entre os pacientes nesses dois grupos de tratamento cirúrgico. Método Foram incluidos neste ensaio clínico randomizado e designados para o grupo controle (neurectomia nasal posterior) ou para o grupo experimental (neurectomia nasal posterior + neurectomia faríngea) 52 pacientes. A escala visual analógica e o questionário de qualidade de vida na rinoconjuntivite (rhinoconjunctivitis quality of life questionnaire) foram usados para comparar as diferenças nos sintomas dos pacientes entre o período inicial e 6, 12 e 24 meses após o tratamento. Além disso, a tosse e os sintomas de asma dos pacientes foram monitorados durante o acompanhamento por meio da escala visual analógica e do teste de controle da asma (asthma control test ), respectivamente. Resultados Nenhuma diferença significante nos escores pré‐operatórios foi evidenciada entre os grupos (p > 0,05). Aos seis meses pós‐tratamento, houve diferenças significantes nos escores da escala visual analógica, no questionário de qualidade de vida na rinoconjuntivite e no teste de controle de asma em relação aos valores basais dos pacientes no grupo experimental e no grupo controle (p < 0,05), o que permaneceu verdadeiro após 12 e 24 meses de acompanhamento. Não foram observadas diferenças significantes nos escores da escala visual analógica e nem no questionário de qualidade de vida para conjuntivite ou no teste de controle da asma entre os dois grupos de tratamento em qualquer momento do acompanhamento pós‐operatório (p > 0,05), enquanto a gravidade da tosse foi significantemente reduzida no grupo experimental em relação ao grupo controle (p < 0,05). Conclusão A neurectomia nasal posterior pôde ser feita com segurança com ou sem neurectomia faríngea para o tratamento eficaz da rinite alérgica. O tratamento combinado com neurectomia nasal posterior e neurectomia faríngea pode oferecer mais benefício do que a neurectomia nasal posterior isolada para o tratamento de pacientes com rinite alérgica e tosse crônica.

Abstract To the mechanism and therapeutic effect of Antelope horn treatment on cerebral ischemia reperfusion injuries under different levels of concentration. The process is as follows: (1) establish MCAO mouse model, test the modelling using traction and open field experiments, use TTC staining to detect the protective effect of Antelope horn treatment on cerebral ischemia reperfusion injury; (2) after 48 h of MCAO, use Nissl staining to measure the extent of hippocampal neuron damage in each group. The hippocampus corner 1 sector and dentate gyrus corner zone of hippocampal neurons of ischemia reperfusion group mouse suffered severe damages under Nissl staining detection. However, the hippocampal neurons of the medicated mouse show obvious alleviation. Western Blot results showed that, compared to the ischemic control group, the Bcl-2, Hsp 27, Hsp 27 expressions of the medicated group were significantly increased, while the Bax expression was dramatically reduced. Immunofluorescence outcome showed obvious reduction of TUNEL and FJB positive cells in the medicated group. That Antelope horn can reduce focal cerebral ischemia reperfusion injury. The reduction of degeneration and apoptosis suggests the correlation between the therapeutic effect of Antelope horn on ischemia reperfusion injury and its anti-apoptotic protective effect.

Abstract Introduction: Diffuse coronary artery disease (CAD) has a poor prognosis and many patients are ineligible for conventional coronary artery bypass grafting (CABG). This study evaluated the 12-month outcomes of coronary artery reconstruction and surgical patch angioplasty of the coronary artery for diffuse CAD. Methods: A retrospective cohort study of patients who underwent CABG with surgical patch angioplasty of the coronary artery (reconstruction group) or standard CABG alone (standard group) at the Cardiovascular Surgery Department of the local Hospital between January 2014 and January 2016. Follow-up was censored at 12 months after surgery. Results: Cardiopulmonary bypass and aortic cross-clamping durations were longer in the reconstruction group (n=32) than in the standard group (n=125) (P<0.05). There were no differences in graft blood flow and postoperative levels of cardiac markers between the two groups (P>0.05). In the reconstruction group, one patient died; a vein graft showed occlusion. In the standard group, two patients died; one left internal mammary artery graft and three vein grafts showed occlusion. There were no significant differences in mortality, major adverse cardiovascular and cerebrovascular events, and patency between the two groups (P>0.05). Conclusion: Coronary artery reconstruction and surgical patch angioplasty of the coronary artery can be performed for diffuse CAD. Patient outcomes were not significantly different from those of patients who underwent standard CABG.
