Objective:To evaluate the Anaplasma phagocytophilum(A.phagocytophilum),Ehrlichia canis(E.canis,Dirofilaria immitis(D.immitis)(canine heartworm),Borrelia burgdorferi(B.burgdorferi)infections in countryside dogs from Yunnan,Hainan and Anhui provinces.Methods:Serum samples were collected from 26 dogs in Yunnan.Hainan and Anhui provinces.The samples were tested using a commercial ELISA rapid diagnostic assay kit(SNAP^(?)4Dx^(?);IDEXX Laboratories,Inc.U.S.A.).Meaiiwliile,indirect immunofluorescence assay(IFA)recommended by WHO was conducted to delect IgG to A.phagocytophilum.Two methods were analyzed and compared.Results:The number of serologically positive dogs for IgG to A.phagocytophilum was only 2which was from Hainan province and none of the 26 dogs responded positive for E.canu.D.immitis(canine heartworm,and B.burgdorferi by ELISA rapid diagnostic method.The number of serologically positive dogs for IgG to A.phagocytophilum was 13(50%)by IFA method.Data of the two methods were analyzed by statistical software and the difference was statistically significant(P=0.002).Conclusions:It can be concluded that IFA method was more sensitive than ELISA rapid diagnostic method.However,we need conduct further and intensive epidemiology survey on tick-born diseases pathogens including.4.phagocytophilum,E.canis,D.immitis(canine heartworm),and B.burgdorferi which have public health significance.

Further Investigation on the Role of Selenium Deficiency in the Aetiology and Pathogenesis of Keshan Disease

Selenium supplements were not able to restore the ultrastructural changes in the myocardiurn of latent Keshan disease patients taken by using cardiac catheter endomyocardial biopsy. Observations on the changes of seleniurn status and the incidence of Keshan disease showed that new latent and naturally-occurring chronic cases were found in the endemic area even after selenium levels had been elevated in the residents to the levels typical in the non-endemic area. These results indicate that although selenium deficiency might be a primary pathogenetic geogen in the occurrence of Keshan disease, it is rather a conditional predisposing factor than a specific or initiative aetiologic factor for the occurrence of Keshan disease. Selenium supplmentation could apparently alleviate the higher platelet responsiveness of residents in the endemic area, which might contribute to eliminating the basis for the occurrence of the multifocal perivascular necroses in myocardium of acute and subacute Keshan disease

Re-examination of statistical relationships between dietary fats and other risk factors,and cardiovascular disease,based on two crucial datasets

Cardiovascular disease(CVD)is the major cause of death in many regions around the world,and several of its risk factors might be linked to diets.To improve public health and the understanding of this topic,we look at the recent Minnesota Coronary Experiment(MCE)analysis that used t-test and Cox model to evaluate CVD risks.However,these parametric methods might suffer from three problems:small sample size,right-censored bias,and lack of long-term evidence.To overcome the first of these challenges,we utilize a nonparametric permutation test to examine the relationship between dietary fats and serum total cholesterol.To address the second problem,we use a resampling-based rank test to examine whether the serum total cholesterol level affects CVD deaths.For the third issue,we use some extra-Framingham Heart Study(FHS)data with an A/B test to look for meta-relationship between diets,risk factors,and CVD risks.We show that,firstly,the link between low saturated fat diets and reduction in serum total cholesterol is strong.Secondly,reducing serum total cholesterol does not robustly have an impact on CVD hazards in the diet group.Lastly,the A/B test result suggests a more complicated relationship regarding abnormal diastolic blood pressure ranges caused by diets and how these might affect the associative link between the cholesterol level and heart disease risks.This study not only helps us to deeply analyze the MCE data but also,in combination with the long-term FHS data,reveals possible complex relationships behind diets,risk factors,and heart disease.

Microstructural damage pattern of vascular cognitive impairment: a comparison between moyamoya disease and cerebrovascular atherosclerotic disease

Moyamoya disease and cerebrovascular atherosclerotic disease are both chronic ischemic diseases with similar presentations of vascular cognitive impairment. The aim of the present study was to investigate the patterns of microstructural damage associated with vascular cognitive impairment in the two diseases. The study recruited 34 patients with moyamoya disease(age 43.9 ± 9.2 years; 20 men and 14 women, 27 patients with cerebrovascular atherosclerotic disease(age: 44.6 ± 7.6 years; 17 men and 10 women), and 31 normal controls(age 43.6 ± 7.3 years; 18 men and 13 women) from Huashan Hospital of Fudan University in China. Cognitive function was assessed using the Mini-Mental State Examination, long-term delayed recall of Auditory Verbal Learning Test, Trail Making Test Part B, and the Symbol Digit Modalities Test. Single-photon emission-computed tomography was used to examine cerebral perfusion. Voxel-based morphometry and tract-based spatial statistics were performed to identify regions of gray matter atrophy and white matter deterioration in patients and normal controls. The results demonstrated that the severity of cognitive impairment was similar between the two diseases in all tested domains. Patients with moyamoya disease and those with cerebrovascular atherosclerotic disease suffered from disturbed supratentorial hemodynamics. Gray matter atrophy in bilateral middle cingulate cortex and parts of the frontal gyrus was prominent in both diseases, but in general, was more severe and more diffuse in those with moyamoya disease. White matter deterioration was significant for both diseases in the genu and body of corpus callosum, in the anterior and superior corona radiation, and in the posterior thalamic radiation, but in moyamoya disease, it was more diffuse and more severe. Vascular cognitive impairment was associated with regional microstructural damage, with a potential link between, gray and white matter damage. Overall, these results provide insight into the pathophysiological nature of vascular cognitive impairment. This study was approved by the Institutional Review Board in Huashan Hospital, China(approval No. 2014-278). This study was registered with ClinicalTrials.gov on December 2, 2014 with the identifier NCT02305407.

A novel method for evaluating brain function and microstructural changes in Parkinson's disease

In this study,microstructural brain damage in Parkinson＇s disease patients was examined using diffusion tensor imaging and tract-based spatial statistics.The analyses revealed the presence of neuronal damage in the substantia nigra and putamen in the Parkinson＇s disease patients.Moreover,disease symptoms worsened with increasing damage to the substantia nigra,confirming that the substantia nigra and basal ganglia are the main structures affected in Parkinson＇s disease.We also found that microstructural damage to the putamen,caudate nucleus and frontal lobe positively correlated with depression.Based on the tract-based spatial statistics,various white matter tracts appeared to have microstructural damage,and this correlated with cognitive disorder and depression.Taken together,our results suggest that diffusion tensor imaging and tract-based spatial statistics can be used to effectively study brain function and microstructural changes in patients with Parkinson＇s disease.Our novel findings should contribute to our understanding of the histopathological basis of cognitive dysfunction and depression in Parkinson＇s disease.

Diagnosis and treatment of an elderly patient with 2019-nCoV pneumonia and acute exacerbation of chronic obstructive pulmonary disease in Gansu Province:A case report

BACKGROUND In December 2019,the first patient with 2019-novel coronavirus(2019-nCoV)was reported in Wuhan,China,and the disease spread rapidly across the country and surrounding countries within 2 mo.As of February 29,2020,a total of 91 confirmed cases had been reported in Gansu Province.This case report of the diagnosis and treatment of an elderly patient with 2019-nCoV pneumonia complicated by acute exacerbation of chronic obstructive pulmonary disease in Gansu Province aims to provide a better reference for the treatment of patients in the future.CASE SUMMARY The patient,a 94-year-old female,lived in Maiji District of Tianshui,Gansu Province,China.On January 30,2020,she was admitted to the Fourth People’s Hospital of Tianshui after 9 d of close contact with a patient with 2019-nCoV pneumonia.She was subsequently admitted to Gansu Provincial Hospital of Traditional Chinese Medicine for isolation and transferred to Tianshui Gansu Provincial Hospital of Infectious Diseases on February 3,2020 for treatment.Upon initial examination,her body temperature was 36.7°C,pulse was 80,breathing was 20,and blood pressure was 130/80 mmHg.She was conscious with normal development and normal nutrition.The pharynx was not red,and bilateral tonsils were not red and swollen.The lungs sounded slightly coarse with no dry or wet rales.The first symptoms were cough and fatigue on 2 February.The patient was hospitalized for 12 d.After active treatment,she was discharged on February 14 with a good prognosis.CONCLUSION A history of exposure to the affected area or patient is a major cause of 2019-nCoV infection,and population clustering is a high risk factor for transmission.Patients may not necessarily have respiratory system symptoms as the only clinical manifestation but may also have concomitant or first onset digestive symptoms.Attention should be paid to the prevention and treatment of multiple organ dysfunction syndrome.Nucleic acid testing is extremely important and needs to be repeated several times.Laboratory and auxiliary examination indicators during the first week of admission are extremely important.It is feasible to carry out dynamic and continuous index monitoring,which can predict and guide the prevention and treatment of multiple organ dysfunction and the prognosis of the disease.

Summary: To investigate the changes in neurological symptoms and signs, as well as serum copper, serum ceruloplasmin after hepatic transplantation in patients with Wilson’s disease, neurological symptoms and signs, serum copper, serum ceruloplasmin before and after hepatic transplantation in 18 patients with Wilson’s disease were observed, and those changes were followed up in 20 non-operative controls treated with penicillamine. Our results showed that the neurological symptoms and signs, serum copper and serum ceruloplasmin were improved in the operative group but deteriorated in the non-operative control group. Our study showed that hepatic transplantation is better than penicillamine in the treatment of Wilson’s disease.

Swarming Computational Techniques for the Influenza Disease System

The current study relates to designing a swarming computational paradigm to solve the influenza disease system(IDS).The nonlinear system’s mathematical form depends upon four classes:susceptible individuals,infected people,recovered individuals and cross-immune people.The solutions of the IDS are provided by using the artificial neural networks(ANNs)together with the swarming computational paradigm-based particle swarmoptimization(PSO)and interior-point scheme(IPA)that are the global and local search approaches.The ANNs-PSO-IPA has never been applied to solve the IDS.Instead a merit function in the sense of mean square error is constructed using the differential form of each class of the IDS and then optimized by the PSOIPA.The correctness and accuracy of the scheme are observed to perform the comparative analysis of the obtained IDS results with the Adams solutions(reference solutions).An absolute error in suitable measures shows the precision of the proposed ANNs procedures and the optimization efficiency of the PSOIPA.Furthermore,the reliability and competence of the proposed computing method are enhanced through the statistical performances.

Application of a biochemical and clinical model to predict individual survival in patients with end-stage liver disease

AIM:To investigate the capability of a biochemical and clinical model,BioCliM,in predicting the survival of cirrhotic patients.METHODS:We prospectively evaluated the survival of 172 cirrhotic patients.The model was constructed using clinical(ascites,encephalopathy and variceal bleeding) and biochemical(serum creatinine and serum total bilirubin) variables that were selected from a Cox proportional hazards model.It was applied to estimate 12-,52-and 104-wk survival.The model's calibration using the Hosmer-Lemeshow statistic was computed at 104 wk in a validation dataset.Finally,the model's validity was tested among an independent set of 85 patients who were stratified into 2 risk groups(low risk≤8 and high risk>8).RESULTS:In the validation cohort,all measures of fi t,discrimination and calibration were improved when the biochemical and clinical model was used.The proposed model had better predictive values(c-statistic:0.90,0.91,0.91) than the Model for End-stage Liver Disease(MELD) and Child-Pugh(CP) scores for 12-,52-and 104-wk mortality,respectively.In addition,the Hosmer-Lemeshow(H-L) statistic revealed that the biochemical and clinical model(H-L,4.69) is better calibrated than MELD(H-L,17.06) and CP(H-L,14.23).There were no significant differences between the observed and expected survival curves in the stratified risk groups(low risk,P=0.61;high risk,P=0.77).CONCLUSION:Our data suggest that the proposed model is able to accurately predict survival in cirrhotic patients.

Preliminary Study on the Occurrence of Maize Diseases in Anhui Province

The occurrence of maize diseases was systematically studied at different growth stages of maize in different areas of Anhui Province. It was found that maize has a long optimal growth period in Anhui Province, and the maize planting structure is complex. The northern region is mainly planted with summer maize in large scale, while the southern region is mainly planted with spring maize in scattered pattern. In terms of diseases, the south spring maize suffered from more diverse diseases than the north summer maize. The main maize disease in Suzhou, Bozhou, Fuyang and Bengbu areas was southern rust, which was common with the highest diseased plant rate of 76%. The main maize diseases in Lu'an, Anqing, Chizhou, Tongling and Xuancheng were rust, maize rough dwarf virus(MRDV), southern leaf blight and sheath blight. Other diseases such as northern leaf blight, stalk rot and maize smut occurred commonly. The diseased plant rate of maize rust was in the range of 25%-47%.
