The noise data is divided into fiveminute segments to calculate the power spectra. The high reference line and low reference line of station are then identified by drawing a probability density function graph( PDF)using the power spectral probability density function. Moreover, according to the anomalies of PDF graphs in 85 seismic stations,the abnormal noise is divided into four categories: dropped packet, low noise, high noise, and median noise anomalies.Afterwards,four selection methods are found by the high or low noise reference line of the stations,and the system of real-time monitoring of seismic noise is formed by combining the four selection methods. Noise records of 85 seismic stations in Fujian Province in July2013 are selected for verification,and the results show that the anomalous noise-recognition system could reach a 90% success rate at most stations and the effect of selection are very good. Therefore,it could be applied to the seismic noise real-time monitoring in stations.展开更多

Affected by environmental factors and many bad living habits such as staying up late, high-fat and high-sugar diet, sedentary behavior and excessive drinking, the function of the body's normal immune system has been destroyed and certain obstacles have emerged, which have led to abnormal proliferation of plasma cells in the bone marrow, serious consequences of canceration, and increasing probability of multiple myeloma. Its occurrence will not only cause bone pain, osteoporosis and other complications, but also cause certain damage to the kidney and pleura, causing patients with low back pain, poor sleep quality, pleurisy lesions, and accompanied by mood irritability, unable to concentrate. Early detection and early treatment are of great significance to the overall therapeutic effect of these patients. This case of multiple myeloma with acute renal failure and multiple pleural nodules as the initial manifestation is reported. The literature is reviewed and discussed in order to improve the clinical understanding of multiple myeloma with extramedullary infiltration and prolong the life cycle of gastric cancer patients to the greatest extent.展开更多

This study aims to investigate brain cognitive alterations and functional plasticity in patients with front lobe tumor at resting-state by conducting functional connectivity density(FCD) mapping and granger causality analysis(GCA). Firstly, FCD mapping was used to extract abnormal functional connectivity(FC) of patients with frontal lobe tumor, and analyzed altered brain FC in both short-and long-range FCD. Then, the voxel-wise GCA method was used to analyze the causal relationship between altered FC regions and other regions in order to detect the time correlation between regions of interest(ROI) and reveal the direction of information flow between brain ROIs. It was found that patients had increased short-range FCD in motor and space attention function areas, had increased short-and long-range FCDs both in Temporal and Insula, and the causal coefficients were changed obviously in Temporal and Frontal. The results show that there is a functional plasticity in space attention function areas. Temporal and Insula are affected by tumor in frontal lobe, and functional reorganization appears inside Temporal.展开更多

文摘The noise data in vertical component records of 85 seismic stations in Fujian Province during 2012 is used as the research object in this paper. The noise data is divided into fiveminute segments to calculate the power spectra. The high reference line and low reference line of station are then identified by drawing a probability density function graph( PDF)using the power spectral probability density function. Moreover, according to the anomalies of PDF graphs in 85 seismic stations,the abnormal noise is divided into four categories: dropped packet, low noise, high noise, and median noise anomalies.Afterwards,four selection methods are found by the high or low noise reference line of the stations,and the system of real-time monitoring of seismic noise is formed by combining the four selection methods. Noise records of 85 seismic stations in Fujian Province in July2013 are selected for verification,and the results show that the anomalous noise-recognition system could reach a 90% success rate at most stations and the effect of selection are very good. Therefore,it could be applied to the seismic noise real-time monitoring in stations.

文摘Cognitive dysfunction stands as a prevalent and consequential non-motor manifestation in Parkinson's disease(PD).Although dysfunction of the olfactory system has been recognized as an important predictor of cognitive decline,the exact mechanism by which aberrant olfactory circuits contribute to cognitive dysfunction in PD is unclear.Here,we provide the first evidence for abnormal functional connectivity across olfactory bulb(OB)and piriform cortex(PC)or entorhinal cortex(EC)by clinical fMRl,and dysfunction of neural coherence in the olfactory system in PD mice.Moreover,we discovered that 2 subpopulations of mitral/tufted(M/T)cells in OB projecting to anterior PC(aPC)and EC precisely mediated the process of cognitive memory respectively by neural coherence at specific frequencies in mice.In addition,the transcriptomic profiling analysis and functional genetic regulation analysis further revealed that biorientation defective 1(Bodl)may play a pivotal role in encoding OB^(M/T)-mediated cognitive function.We also verified that a new deep brain stimulation protocol in OB ameliorated the cognitive function of Bodl-deficient mice and PD mice.Together,aberrant coherent activity in the olfactory system can serve as a biomarker for assessing cognitive function and provide a candidate therapeutic target for the treatment of PD.
文摘Potential causes of abnormal liver function tests include viral hepatitis,alcohol intake,nonalcoholic fatty liver disease,autoimmune liver diseases,hereditary diseases,hepatobiliary malignancies or infection,gallstones and drug-induced liver injury.Moreover,the liver may be involved in systemic diseases that mainly affect other organs.Therefore,in patients without etiology of liver injury by screening serology and diagnostic imaging,but who have systemic diseases,the abnormal liver function test results might be caused by the systemic disease.In most of these patients,the systemic disease should be treated primarily.However,some patients with systemic disease and severe liver injury or fulminant hepatic failure require intensive treatments of the liver.

文摘Background and Aims:Anti-tuberculosis(anti-TB)druginduced liver injury(AT-DILI)is the most common side effect in patients who received anti-TB therapy.AT-DILI management includes monitoring liver function until symptoms arise in patients without high-risk factors for liver damage.The present study aimed to investigate the effect of liver function test(LFT)abnormal identification on the risk of DILI,including liver failure and anti-TB drug resistance in patients without high-risk factors.Methods:A total of 399 patients without high-risk factors for liver damage at baseline and who experienced LFT abnormal during the 6 months of first-line anti-TB treatment were enrolled.The Roussel Uclaf Causal Relationship Assessment Method(RUCAM,2016)was applied in suspected DILI.The correlations between the time of LFT abnormal identification and DILI,liver failure,and anti-TB drug resistance were analyzed by smooth curve fitting and multivariable logistic regression models.Results:Among all study patients,131 met the criteria for DILI with a mean RUCAM causality score of 8.86±0.63.26/131 and 105/131 were in the probable grading and highly probable grading,respectively.The time of abnormal LFT identification was an independent predictor of DILI,liver failure,and anti-TB drug resistance in the crude model and after adjusting for other risk patient factors.The time of abnormal LFT identification was positively correlated with DILI,liver failure,and anti-TB drug resistance.The late identification group(>8 weeks)had the highest risk of DILI,followed by liver failure compared with the other two groups.Conclusions:The time to identification of LFT was positively correlated with DILI,liver failure,and anti-TB drug resistance.The risk of DILI and liver failure was significantly increased in the late identification group with abnormal LFT identified after 8 weeks compared with 4 and 8 weeks.Early monitoring of LFT is recommended for patients without the high-risk factor of DILI after anti-TB treatment is initiated.

文摘Today, China's economy is developing faster and faster, and people's living standard and quality are also gradually improving. Affected by environmental factors and many bad living habits such as staying up late, high-fat and high-sugar diet, sedentary behavior and excessive drinking, the function of the body's normal immune system has been destroyed and certain obstacles have emerged, which have led to abnormal proliferation of plasma cells in the bone marrow, serious consequences of canceration, and increasing probability of multiple myeloma. Its occurrence will not only cause bone pain, osteoporosis and other complications, but also cause certain damage to the kidney and pleura, causing patients with low back pain, poor sleep quality, pleurisy lesions, and accompanied by mood irritability, unable to concentrate. Early detection and early treatment are of great significance to the overall therapeutic effect of these patients. This case of multiple myeloma with acute renal failure and multiple pleural nodules as the initial manifestation is reported. The literature is reviewed and discussed in order to improve the clinical understanding of multiple myeloma with extramedullary infiltration and prolong the life cycle of gastric cancer patients to the greatest extent.

文摘At present, the neuropathological mechanisms and the plastic changes of brain cognitive function in patents with front lobe tumor remain unclear, most studies just focused on global measures of brain functional connectivity without considering the time correlation in the different regions of the brain. This study aims to investigate brain cognitive alterations and functional plasticity in patients with front lobe tumor at resting-state by conducting functional connectivity density(FCD) mapping and granger causality analysis(GCA). Firstly, FCD mapping was used to extract abnormal functional connectivity(FC) of patients with frontal lobe tumor, and analyzed altered brain FC in both short-and long-range FCD. Then, the voxel-wise GCA method was used to analyze the causal relationship between altered FC regions and other regions in order to detect the time correlation between regions of interest(ROI) and reveal the direction of information flow between brain ROIs. It was found that patients had increased short-range FCD in motor and space attention function areas, had increased short-and long-range FCDs both in Temporal and Insula, and the causal coefficients were changed obviously in Temporal and Frontal. The results show that there is a functional plasticity in space attention function areas. Temporal and Insula are affected by tumor in frontal lobe, and functional reorganization appears inside Temporal.

文摘Clinical cases have reported pulmonary arterial structural and functional abnormalities in patients with Kawasaki disease(KD);however,the underlying mechanisms are unclear.In this study,a KD rat model was established via the intraperitoneal injection of Lactobacillus casei cell wall extract(LCWE).The results showed that pulmonary arterial functional and structural abnormalities were observed in KD rats.Furthermore,proliferative endoplasmic reticulum stress(ER stress)was observed in the pulmonary arteries of KD rats.Notably,the level of lipocalin-2(Lcn 2),a trigger factor of inflammation,was remarkably elevated in the plasma and lung tissues of KD rats;increased Lcn 2 levels following LCWE stimulation may result from polymorphonuclear neutrophils(PMNs).Correspondingly,in cultured pulmonary artery smooth muscle cells(PASMCs),Lcn 2 markedly augmented the cleavage and nuclear localization of activating transcription factor-6(ATF6),upregulated the transcription of glucose regulated protein 78(GRP78)and neurite outgrowth inhibitor(NOGO),and promoted PASMCs proliferation.However,proapoptotic C/EBP homologous protein(CHOP)and caspase 12 levels were not elevated.Treatment with 4-phenyl butyric acid(4-PBA,a specific inhibitor of ER stress)inhibited PASMCs proliferation induced by Lcn 2 and attenuated pulmonary arterial abnormalities and right ventricular hypertrophy and reduced right ventricular systolic pressure in KD rats.In conclusion,Lcn 2 remarkably facilitates proliferative ER stress in PASMCs,which probably accounts for KD-related pulmonary arterial abnormalities.

文摘To date,it remains unclear if severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)co-infection exacerbates liver injury in patients with chronic hepatitis B virus(HBV)infection.In this study,we present a retrospective study of 133 hospitalized confirmed mild coronavirus disease 2019(COVID-19)cases,including 116 patients with COVID-19 with negative serum hepatitis B antigen and 17 HBV inactive carriers with COVID-19.We found that there were no significant differences for the discharge rate or duration of hospitalization be-tween the two groups.However,inactive HBV carriers with SARS-CoV-2 co-infection are at a higher risk of abnormal liver function tests.The enhanced liver injury induced by SARS-CoV-2 and HBV co-infection was identified as the hepatocyte type rather than the cholangiocyte type.Moreover,the inflammatory response,including abnormal lactate dehydrogenase,D-dimer and interleukin-6 production,may contribute to this injury following SARS-CoV-2 co-infection.Collectively,SARS-CoV-2 and HBV co-infection exacerbates liver function of the pa-tients with COVID-19.

文摘Pregnancy with solid pseudopapillary tumor of the pancreas(SPTP)is rare.Because pregnancy hormones may cause tumor progression,the management and treatment of SPTP need to balance the safety of pregnant women and fetuses with surgical treatment.We reported a case of a giant pancreatic tumor diagnosed during pregnancy that was considered to be SPTP.Examinations also showed hepatitis B virus infection and severe decompensation of liver cirrhosis.Medical termination of pregnancy was performed.The patient has lived with the tumor until now without surgery.We retrieved the published case reports,summarized the clinical characteristics of pregnancy with SPTP,and explored its management during the perinatal period.Most patients with SPTP have a good prognosis with good maternal and fetal outcomes,and it is important to choose an appropriate treatment method and timing.However,pregnancy combined with decompensated liver cirrhosis needs to be terminated in a timely manner because of its high-risk status.
