Psychiatric disorders and heart abnormality are closely interconnected.Previous knowledge has been well-established that psychiatric disorders can lead to increased cardiovascular morbidity and even sudden cardiac death.Conversely,whether heart abnormality contributes to psychiatric disorders remains rarely studied.The work by Zhang et al pointed out that chronic heart failure had effects on the anxiety and depression(AD)severity,and indices including left ventricular ejection fraction,N-terminal pro-brain natriuretic peptide and interleukin-6 were independent risk factors for AD severity.In addition to the aforementioned AD,we herein find that heart failure might additionally impact the development of autism spectrum disorder and post-traumatic stress disorder(albeit P>0.05),and significantly protects against the presence of attention deficit hyperactivity disorder(ADHD),[odds ratio(OR)=0.61,P=0.0071]by using a Mendelian randomization analysis.Bradycardia is also a protective factor for ADHD(OR=0.61,P=0.0095),whereas hypertrophic cardiomyopathy is a mild risk factor for schizophrenia(OR=1.02,P=0.032).These data suggest a wide spectrum of psychiatric disorders secondary to heart abnormality,and we highlight more psychiatric care that should be paid to patients with heart abnormality. 展开更多

BACKGROUND Few studies have reported an association between an increased risk of acquiring cancers and survival in patients with 4q deletion syndrome.This study presents a rare association between chromosome 4q abnormalities and fallopian tube highgrade serous carcinoma(HGSC)in a young woman.CASE SUMMARY A 35-year-old woman presented with acute dull abdominal pain and a known chromosomal abnormality involving 4q13.3 duplication and 4q23q24 deletion.Upon arrival at the emergency room,her abdomen appeared ovoid and distended with palpable shifting dullness.Ascites were identified through abdominal ultrasound,and computed tomography revealed an omentum cake and an enlarged bilateral adnexa.Blood tests showed elevated CA-125 levels.Paracentesis was conducted,and immunohistochemistry indicated that the cancer cells favored an ovarian origin,making us suspect ovarian cancer.The patient underwent debulking surgery,which led to a diagnosis of stage IIIC HGSC of the fallopian tube.Subsequently,the patient received adjuvant chemotherapy with carboplatin and paclitaxel,resulting in stable current condition.CONCLUSION This study demonstrates a rare correlation between a chromosome 4q abnormality and HGSC.UBE2D3 may affect crucial cancer-related pathways,including P53,BRCA,cyclin D,and tyrosine kinase receptors,thereby possibly contributing to cancer development.In addition,ADH1 and DDIT4 may be potential influencers of both carcinogenic and therapeutic responses. 展开更多

BACKGROUND Liver function of chronic hepatitis B(CHB)patients is essentially normal after treatment with antiviral drugs.In rare cases,persistently abnormally elevatedα-fetoprotein(AFP)is seen in CHB patients following long-term antiviral treatment.However,in the absence of imaging evidence of liver cancer,a reasonable expla-nation for this phenomenon is still lacking.AIM To explore the causes of abnormal AFP in patients with CHB who were not diag-nosed with liver cancer.METHODS From November 2019 to May 2023,15 patients with CHB after antiviral treatment and elevated AFP were selected.Clinical data and quality indicators related to laboratory testing,imaging data,and pathological data were obtained through inpatient medical records.RESULTS All patients had increased AFP and significantly elevated IgG.Cancer was excluded by imaging examination.Only four patients had elevated alanine ami-notransferase,10 had elevated aspartate aminotransferase,nine had elevated total bilirubin,and two had antinuclear antibodies.The liver biopsy and histopatho-logical examination indicated that 14 patients had rosette,moderate,or higher interfacial inflammation,lymphocyte infiltration,and severe hepatic fibers(11 cases),which was consistent with the pathological features of autoimmune hepa-titis(AIH).After 8-12 week of hormone therapy,the levels of AFP and IgG,and liver function returned to normal(P<0.05).CONCLUSION For patients with CHB and elevated AFP after antiviral treatment,autoimmune hepatitis should be considered.CHB with AIH is clinically insidious and difficult to detect,and prone to progression to cirrhosis.Liver puncture pathological examination should be performed when necessary to confirm diagnosis. 展开更多

By measuring M-T curves, ρ-T curves and MR-T curves of the samples under different temperatures, the influence of Dy doping (0.00 ≤ x ≤0.30) on the magnetic and electric properties of La0.7-xDyxSr0.3MnO3 has been studied. The experimental results show that, with the increase of the Dy content, the system undergoes a transition from long range ferromagnetic order to the cluster-spin glass state and further to antiferromagnetic order. For the samples with x=0.20 and 0.30, their magnetic behaviors are abnormal at low temperature, and their resistivities at low temperature have a minimum value. These peculiar phenomena not only come from the lattice effect induced by doping, but also from extra magnetic coupling induced by doping. 展开更多

Tooth number abnormality is one of the most common dental developmental diseases,which includes both tooth agenesis and supernumerary teeth.Tooth development is regulated by numerous developmental signals,such as the well-known Wnt,BMP,FGF,Shh and Eda pathways,which mediate the ongoing complex interactions between epithelium and mesenchyme.Abnormal expression of these crutial signalling during this process may eventually lead to the development of anomalies in tooth number;however,the underlying mechanisms remain elusive.In this review,we summarized the major process of tooth development,the latest progress of mechanism studies and newly reported clinical investigations of tooth number abnormality.In addition,potential treatment approaches for tooth number abnormality based on developmental biology are also discussed.This review not only provides a reference for the diagnosis and treatment of tooth number abnormality in clinical practice but also facilitates the translation of basic research to the clinical application. 展开更多

By use of the filter analysis technique, the Complex Empirical Othogonal Function (CEOF) method and the ECMWF/WMO 2.5°×2.5°grid data of the geopotential heights during the summer months in 1988, an interseasonal process that the western Pacific subtropical high (WPSH) was anomalously far to the north in the first and second ten days of July is studied. It has been found that in the western Pacific subtropical region in the first and second ten days of July,it is the continuous assembly of low frequency geopotential waves (LFGWs) that leads to the abnormality of WPSH. This abnormality emerges with the enhancement of wave assembling and ceases while the wave assembling situation disappears. The structure of the low frequency assembling waves corresponds to the structure of subtropical high in its abnormal period. The effect of the assembling waves on the abnormality of subtropical high can be considered as the accumulation of disturbance energy carried by the low frequency waves from different directions in the western Pacific region. 展开更多

Objective This study aimed to investigate the expression pattern and function of Nuclear receptor subfamily 2 group E member 1 (Nr2e1) in retinoic acid (RA)-induced brain abnormality. Methods The mouse model of brain abnormality was established by administering 28 mg/kg RA, and neural stem cells (NSCs) were isolated from the mouse embryo and cultured in vitro. Nr2e1 expression was detected by whole mount in situ hybridization, RT-PCR, and Western blotting. Nr2e1 function was determined by transducing Nr2e1 sh RNA into NSCs, and the effect on the sonic hedgehog (Shh) signaling pathway was assessed in the cells. In addition, the regulation of Nr2e1 expression by RA was also determined in vitro. Results Nr2e1 expression was significantly downregulated in the brain and NSCs of RA-treated mouse embryos, and knockdown of Nr2e1 affected the proliferation of NSCs in vitro. In addition, a similar expression pattern of Nr2e1 and RA receptor (RAR) α was observed after treatment of NSCs with different concentrations of RA. Conclusion Our study demonstrated that Nr2e1 could be regulated by RA, which would aid a better understanding of the mechanism underlying RA-induced brain abnormality. 展开更多

By using ECMWF (2. 5°×2. 5°) grid data, analyzing correlation for the summer (June-August) of 1980 (the West Pacific Subtropical High (WPSH) anomalously more to the south), 1988 (the WPSH anomalously more to the north), 1981 (normal) in the west Pacific area, distribution characteristics of the low frequency waves are discussed. The relationship between distribution of the low frequency waves and intraseasonal abnormality of the west subtropical high is also analyzed. There is some discussions:(1)If the WPSH acts anomalously in summer, there is a distinct zonal wave series in the subtropical zone of the north Pacific.(2) One of the important characteristics of the WPSH abnormality is that there are low frequency geopotential high centres from east Pacific and northeast Asia, being combined in the west Pacific area.For different circulation, the combination areas are different, which define the WSPH anomalously more to the north or south. 展开更多

By using the historical data during 1953-2009,the yearly most wind direction change in Yumen and the meteorological disasters of 4 times yearly most wind direction abnormality in recent 57 years were analyzed. The results showed that there were 51 years which the yearly most wind direction was the easterlies in Yumen,and the westerly had 4 years. There were 2 years which the occurrence frequencies of westerly and easterlies were same. 4 years which the yearly wind direction abnormality was the most were in 1961,1979,1987 and 1998. When the yearly wind direction abnormality was the most,the meteorological disaster was serious. The total output of grain in Gansu Province in 1961 was the least in the history in recent 60 years. The serious drought disaster in 1961 caused that half agricultural population in Gansu seriously lacked of the grain,and the dead population sharply increased. In the end of 1961,the population in Gansu decreased nearly million than in 1958. The annual precipitation in 1979 was the most in recent 57 years. The daily precipitation on June 11,1987 was the most in June of recent 57 years in Yumen. The annual average temperature in 1998 was the highest in Yumen in recent 57 years. 展开更多

Our previous study used regional homogeneity analysis and found that activity in some brain areas of patients with ischemic stroke changed significantly. In the current study, we examined structural changes in these brain regions by taking structural magnetic resonance imaging scans of 11 ischemic stroke patients and 15 healthy participants, and analyzing the data using voxel-based morphometry. Compared with healthy participants, patients exhibited higher gray matter density in the left inferior occipital gyrus and right anterior white matter tract. In contrast, gray matter density in the right cerebellum, left precentral gyrus, right middle frontal gyrus, and left middle temporal gyrus was less in ischemic stroke patients. The changes of gray matter density in the middle frontal gyrus were negatively associated with the clin- ical rating scales of the Fugl-Meyer Motor Assessment (r = -0.609, P = 0.047) and the left middle temporal gyrus was negatively correlated with the clinical rating scales of the nervous functional deficiency scale (r = -0.737, P = 0.010). Our findings call objectively identify the functional abnormality in some brain regions of ischemic stroke patients. 展开更多

Online monitoring methods have been widely used in many major devices, however the normal and abnormal states of equipment are estimated mainly based on the monitoring results whether monitored parameters exceed the setting thresholds. Using these monitoring methods may cause serious false positive or false negative results. In order to precisely monitor the state of equipment, the problem of abnormality degree detection without fault sample is studied with a new detection method called negative potential field group detectors(NPFG-detectors). This method achieves the quantitative expression of abnormality degree and provides the better detection results compared with other methods. In the process of Iris data set simulation, the new algorithm obtains the successful results in abnormal detection. The detection rates for 3 types of Iris data set respectively reach 100%, 91.6%, and 95.24% with 50% training samples. The problem of Bearing abnormality degree detection via an abnormality degree curve is successfully solved. 展开更多

Depression and cardiovascular disease (CVD) are both highly prevalent disorders, and some evidence shows that there is a 'vicious cy- cle' linking major depression and CVD. There is also growing evidence that immune abnormalities underpin the common pathophysiology of both CVD and major depression. The abnormalities include the following: abnormal levels of inflammatory markers, such as interleukin-6 (IL-6), interleukin-1β (IL-1β), minor necrosis factor α (TNF-α) and interleukin-12 (IL-12); increased acute phase proteins, such as C-reactive protein, fibrinogen and haptoglobin; and abnormal complement factors. The findings show that major depression and CVD patients have greater immune abnormalities, which may increase depressive symptoms and cardiovascular pathological changes, and that there may be a bidirectional relationship, therefore more prospective studies are needed to draw conclusions. 展开更多

Objective: Embryonic chromosomal abnormality is one of the main reasons for in vitro fertilization (IVF) failure. This study aimed at evaluating the value of Fluorescence in-situ Hybridization (FISH)-based Preimplantation Genetic Diagnosis (PGD) in screening for embryonic chromosomal abnormality to increase the successful rate of IVF. Method: Ten couples, four with high risk of chromosomal abnormality and six infertile couples, underwent FISH-based PGD during IVF procedure. At day 3, one or two blastomeres were aspirated from each embryo. Biopsied blastomeres were examined using FISH analysis to screen out embryos with chromosomal abnormalities. At day 4, embryos without detectable chromosomal abnormality were transferred to the mother bodies as in regular IVF. Results: Among 54 embryos screened using FISH-based PGD, 30 embryos were detected to have chromosomal abnormalities. The 24 healthy embryos were implanted, resulting in four clinical pregnancies, two of which led to successful normal birth of two healthy babies; one to ongoing pregnancy during the writing of this article; and one to ectopic pregnancy. Conclusion: FISH-based PGD is an effective method for detecting embryonic chromosomal abnormality, which is one of the common causes of spontaneous miscarriages and chromosomally unbalanced offsprings. 展开更多

Fluorescence in situ Hybridization (FISH) was used to investigate whether the chromosome of the fetus prenatally diagnosed as pyelectasis was normal or not. Amniotic fluid was taken from the pregnant woman whose fetus was detected with pyelectasia by prenatal examination. The chromosome of the amniotic fluid cell without culture was examined with FISH. The result shows that compared with the traditional amniotic fluid cell culture, FISH has the advantages of more rapid, higher sensitivity and specificity, and was 10-12 days earlier to complete the diagnosing than the traditional method. The fetuses detected chromosomal abnormality in each groups were induced during the middle and late trimester, while those fetuses with normal chromosome continued pregnancy, the rate of spontaneous disappearance of pyelectasia decreased as the severity of pyelectasia increased. FISH can satisfy the urgent need in the clinical prenatal diagnosis due to its rapidity to determine whether fetus with pyelectasia was accompanied with chromosomal. 展开更多

To study the technique of D-FISH and its application in the diagnosis of a 49, XXXXY chromosomal abnormality. Methods: Biotin-labeled alpha satellite X chromosome DNA (pBamX7) probe and digoxi-genin-labeled Y chromosome long arm terminal repetitive sequence (pY3.4) probe in situ hybridized with pre-treated slides of peripheral blood chromosome and interphase nucleus. After washing, the slides were treated with avidin-FITC, rhodamine-FITC and anti-avidin, amplified with an additional layer and counter-stained with DAPI in an antifade solution. The hy bridization signals and chromosomal or interphase nucleus settings were observed respectively with WIB, WIG and WU filters under fluorescent microscope (Olympus AX-70) and the number of metaphase chromosome and interphase nucleus in the peripheral blood was counted. Results: The biotin-labeled pBamX7 probe showed 4 green hybridization signal and the digoxigenin-labeled pY3.4 probe showed 1 red hybridization signal. The chromosome or cytoplasm counter-stained with DAPI showed blue. The positive rate of X chromosome hybridization signal for the 350 metaphase chromosomes and interphase nucleus was 91.43 % and 92. 57 %, respectively, while that of the Y chromosome hybridization signal was 99.5 % and 99.8 %, respectively. Conclusion: D-FISH is a valuable technique in diagnosing 49, XXXXY chromosomal abnormality and other sex chromosomal abnormalities. [Reprod Contracep (in Chinese) 2002; 22: 287] 展开更多

Residual stresses in ferromagnetic material affect the direction and structure of domains and generate magnetic field abnormality on the surface. In the formation of stress induced magnetic field, the influence of geomagnetic field is unclear. Residual stress specimen was produced by tight matching of a round ring and a peg. The magnetic fields of contrast specimens, which were produced in geomagnetic field or in shielding geomagnetic field, were inspected with 8 mm lift-off. The results show that mean amplitude of magnetic field of the specimen produced in geomagnetic field is 0.85% larger than that of specimen produced in shielding geomagnetic field. So the formation of stress induced magnetic field abnormality above the surface of inspected ferromagnetic material geomagnetic field gives little contribution. 展开更多
