Background Ongoing debates question the harm of internet use with the evolving technology,as many individuals transition from regular to problematic internet use(PIU).The habenula(Hb),located between the thalamus and the third ventricle,is implicated in various psychiatric disorders.In addition,personality features have been suggested to play a role in the pathophysiology of PIU.Aims This study aimed to investigate Hb volumetry in individuals with subclinical PIU and the mediating effect of personality traits on this relationship.Methods 110 healthy adults in this cross-sectional study underwent structural magnetic resonance imaging.Hb segmentation was performed using a deep learning technique.The Internet Addiction Test(IAT)and the NEO Five-Factor Inventory were used to assess the PIU level and personality,respectively.Partial Spearman's correlation analyses were performed to explore the reiationships between Hb volumetry,IAT and NEO.Multiple regression analysis was applied to identify personality traits that predict IAT scores.The significant trait was then treated as a mediator between Hb volume and IAT correlation in mediation analysis with a bootstrap value of 5000.Results Relative Hb volume was negatively correlated with IAT scores(partial rho=-0.142,p=0.009).The IAT score was positively correlated with neuroticism(partial rho=0.430,p<0.001)and negatively correlated with extraversion,agreeableness and conscientiousness(partial rho=-0.213,p<0.001;partial rho=-0.279,p<0.001;and partial rho=-0.327,p<0.001).There was a significant indirect effect of Hb volume on this model(β=-0.061,p=0.048,boot 95%confidence interval:-0.149 to-0.001).Conclusions This study uncovered a crucial link between reduced Hb volume and heightened PIU.Our findings highlight neuroticism as a key risk factor for developing PIU.Moreover,neuroticism was shown to mediate the relationship between Hb volume and PIU tendency,offering valuable insight into the complexities of this interaction. 展开更多

Background Subclinical mastitis,caused by many pathogens including Staphylococcus aureus(S.aureus)and Staphylococcus chromogenes(S.chromogenes),presents a major challenge to the dairy industry due to its associated economic losses and poor milk quality.The molecular regulatory mechanisms,including the role of small nucleolar RNAs(snoRNAs),of the host response to mastitis pathogens remain unclear.Therefore,this study investigated snoRNA expression and potential roles during subclinical mastitis.Milk somatic cells from cows with naturally occurring S.aureus(n=14)and S.chromogenes(n=3)subclinical mastitis,and healthy cows(n=4)were subjected to transcriptome sequencing and bioinformatics analyses.Results We identified 255 expressed snoRNAs including 21 differentially expressed(DE)in S.aureus-positive cows and 20 DE in S.chromogenes-positive cows.Prediction of ribosomal RNA(rRNA)modification sites found several 18S rRNA and 28S rRNA modification(pseudouridylation and 2′-O-methylation)target sites essential for ribosome function for DE snoRNAs,such as SNORA79(18S-1319,28S-3001),SNORA1(18S-1496,28S-1747),suggesting their roles in translation and immune modulation during subclinical mastitis.Correlation analysis identified DE snoRNAs-mRNAs(from the same samples)pairs with majority of the correlated mRNAs(e.g.,CXCL8,IL6R,IL2,IL1R,IL18R1,STAT3,NFKB2,MYD88,VEGFA,and CD40)having immune related functions.Functional enrichment of correlated genes of snoRNAs for S.aureus-positive group(regulation of defense/immune response,leukocyte differentiation,response to cytokine,NF-κB signaling pathway,JAK-STAT signaling pathway etc.)and S.chromogenes-positive group(e.g.,regulation of defense response,response to cytokine,regulation of immune response,NF-κB signaling pathway,TNF signaling pathway,and JAK-STAT signaling pathway)revealed involvement in immune and inflammatory processes.Some functional terms were common to both pathogens(e.g.,NF-κB,JAK-STAT signaling,immune system processes)and suggest common regulatory mechanisms used by both pathogens to contain infection.Furthermore,snoRNA-mRNA network construction identified 7 key(hub)snoRNAs each for S.aureus-positive group(SNORA66,novelsnoRNA_26_14905(also denoted as novelSnoRNA_86),SNORD107,SNORA1,SNORA63,SNORA79,SNORA76)and S.chromogenes-positive group(SNORD18,SNORA79,SNORA46,U2-19,SNORA66,SNORD37,SNORD49)that correlated with the most protein coding genes(|r|>0.9;≥30 mRNAs).Functional enrichment of correlated genes of hub snoRNAs reveals their involvement in immune related functions(75%of enriched terms)and metabolic processes(20%of enriched terms).Conclusion These data suggest potential regulatory roles for the DE snoRNAs and in particular,the 14 hub snoRNAs during subclinical mastitis.This study presents the first evidence linking snoRNAs to bovine subclinical mastitis and offers new insights into the molecular mechanisms underlying subclinical mastitis caused by S.aureus and S.chromogenes. 展开更多

Background Sustained lipolysis exacerbates subclinical ketosis(SCK)in dairy cows and is associated with inflammation and adipose tissue macrophage(ATM)infiltration.While ATM involvement in adipose homeostasis and inflammation in early lactation is recognized,a comprehensive exploration of ATM polarization phenotypes in SCK cows is lacking.This study aimed to characterize ATM polarization and its link to lipolysis and inflammation in SCK cows.Results Subcutaneous adipose tissue samples were obtained from dairy cows to analyze protein expression and gene profiles.Compared with healthy cows,SCK cows had higher serum BHBA and NEFA,smaller adipocytes,and increased expression of lipolytic enzymes(LIPE,ATGL),indicating enhanced lipolysis.Decreased levels of FASN,PPARγ,p-SMAD3,and TGFβsuggested impaired adipogenesis.Inflammatory markers(TNF-α,IFN-γ,TLR4,Caspase1)and NFκB signaling activity were elevated.ATM infiltration was supported by increased CD9,CD68,TREM2,and CXCL1 expression.Protein abundance of M1 polarization markers(iNOS,CD86 and CCL2)in ATMs were associated with greater levels of NOS2,IL1B,CD86 and CCL2 mRNA expression in SCK cows;fluorescence intensity of NOS2 and CD86 also was elevated,alongside a higher proportion of CD68+/CD86+immunopositive cells within adipose tissue.ELISA further quantified increased concentrations of IL-1β and CCL2.Conversely,the abundance of ATM M2 polarization markers,including CD206,IL-10,KLF4,and Arg1,at both the protein and mRNA levels demonstrated a decline.Meanwhile,the proportion of CD68+/CD206+immune response cells was relatively low in SCK cows.Conclusions Overall,the present study indicated an augmented macrophage presence within adipose tissue during subclinical ketosis,with a predominance of pro-inflammatory macrophages(M1 ATM).This observation suggested a vicious cycle wherein macrophage infiltration and pro-inflammatory polarization coincide with enhanced lipolysis and an amplified inflammatory cascade. 展开更多

Objective To assess the relationships between iodine biological exposure and subclinical thyroid dysfunctions. Methods The cross-sectional survey was performed to obtain the epidemiologic data of population in three communities with different iodine biological exposure: mild iodine deficiency [median urinary iodine concentration (MUI) of 50-99 μg/L], more than adequate iodine intake (MUI of 200-299 μg/L), and excessive iodine intake (MUI over 300 μg/L). Univariate and multivariate analysis (logistic regression analysis) were used to analyze the risk factors of subclinical hypothyroidism and subclinical hyperthyroidism. Logistic regression analysis with sex and age controlled suggested that more than adequate iodine intake (OR = 3.172, P = 0.0004) and excessive iodine intake (OR = 6.391, P = 0.0001) increased the risk of subclinical hypothyroidism, while excessive iodine intake decreased the risk of subclinical hyperthyroidism (OR = 0.218, P= 0.0001). Logistic regression analysis including interaction of iodine intake and antibodies [tryroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb)] suggested that excessive iodine intake was an independent risk factor of subclinical hypothyroidism (OR = 6.360, P= 0.0001), but independent protect factor of subclinical hyperthyroidism (OR = 0.193, P= 0.0001). More than adequate iodine intake and it's interaction with TgAb increased the risk of subclinical hypothyroidism independently, in addition, it decreased the risk of subclinical hyperthyroidism at the present of TPOAb. Conclusion Both excessive iodine intake and more than adequate iodine intake could increase risk of subclinical hypothyroidism, supplement of iodine should be controlled to ensure MUI within the safe range. 展开更多

Background: Subclinical necrotic enteritis(SNE), a common intestinal disease of broiler caused by Clostridium perfringens, could reduce production performance of broilers by chronic intestinal damage and poor absorption of nutrients. Ellagic acid(EA) has been reported to present antioxidant and anti-inflammatory properties on human and animals in many aspects. This study was conducted to evaluate the effect and mechanism of EA in relieving SNE in broilers induced by C. perfringens.Results: C. perfringens challenge decreased body weight(BW), average daily gain(ADG), jejunal villi height/crypt depth(V/C) ratio, the activity of catalase(CAT) and the mRNA expression of zonula occludens 1(ZO-1) in jejunal mucosa of broilers. While feed conversion ratios(FCR), jejunal crypt depth(CD), the activities of myeloperoxidase(MPO) and diamine oxidase(DAO), as well as the concentrations of interleukin 6(IL-6), C-reactive protein(CRP) and procalcitonin(PCT) in serum, the activities of inducible nitric oxide synthase(iNOS) and lysozyme(LZM), the concentration of malondialdehyde(MDA), and the mRNA expressions of claudin-2, TNF-α, IL-1β, TLR-4, TLR-2, NF-κB,JAK3, STAT6 and iNOS in jejunal mucosa of broilers were increased by C. perfringens challenge. Dietary EA supplement relieved these adverse effects, and heightened jejunal villi height(VH), the concentration of D-xylose in plasma, activity of superoxide dismutase(SOD), and the mRNA expression of occludin in jejunal mucosa of broilers.The alpha diversity of cecal microbiota indicated that dietary EA supplement increased observed species and Shannon index. C. perfringens challenge increased the relative abundance of Firmicutes and decreased the relative abundance of Desulfobacterota in cecal microbiota. EA increased the relative abundance of Firmicutes in cecal microbiota. LEfSe analysis showed that C. perfringens challenge triggered the imbalance of cecal microbiota in broilers, dietary EA supplementation led to a small beneficial effect on microbiota, while the simultaneous effect of them seemed to stimulate the immune function of broilers by improving the microbiota balance.Conclusions: Dietary EA ameliorated C. perfringens-induced SNE in broilers via regulating jejunal inflammation signaling pathways TLR/NF-κB and JAK3/STAT6, relieving jejunal oxidative stress and balancing cecal microbiota to inhibit intestinal barrier damage, prevent systemic inflammatory response and improve nutrient absorption capacity,finally protect and enhance growth performance of broilers. 展开更多

This study determined the prevalence of diabetic peripheral neuropathy(DPN) and subclinical DPN(s DPN) in patients with type 2 diabetes mellitus(T2DM) using nerve conduction study(NCS) as a diagnostic tool. We also investigated the factors associated with the development of s DPN and compared factors between the sD PN and confirmed DPN(cDPN). This cross-sectional study involved 240 T2DM patients who were successively admitted to the endocrinology wards of Wuhan Union Hospital over the period of January to December 2014. Data on the medical history, physical and laboratory examinations were collected. DPN was diagnosed using NCS. One-way ANOVA with least significant difference(LSD) analysis or chi-square tests was used to compare parameters among DNP-free, s DPN and c DPN patients. Independent factors associated with s DPN were determined using logistic regression. The results showed that 50.8% of the participants had DPN, and among them, 17.1% had sDPN. sDPN showed significant independent associations with age, height, HbA1c, presence of atherosclerosis and diabetic retinopathy. Patients with DPN differed significantly from those without DPN with respect to age, duration of disease(DOD), HbA1c, presence of atherosclerosis, diabetic retinopathy, nephropathy and hypertension. Patients with cDPN, relative to those with sDPN, had significantly longer DOD and higher prevalence of peripheral artery disease(PAD) and coronary artery disease(CAD). Our study suggests that a significant number of T2DM patients are affected by s DPN, and the development of this condition is associated with advanced age, tall stature, poor glycaemic control, presence of diabetic retinopathy and atherosclerosis. On the other hand, patients with cDPN tend to have a longer DOD and are more likely to suffer from PAD and CAD. 展开更多

To evaluate the month-wise prevalence of subclinical mastitis (SM) and its relations with climatic temperature and humidity, and to provide references for control and prevention of mastitis in dairy cows in Guangdong, China, California mastitis test method was used to determine the monthly prevalence of SM (MPSM, %) of lactating Holstein cows from 11 dairy farms in Guangdong Province, China, including about 516 cows per monthly examination. The average MPSM on a cow and a quarter basis were 30 and 13% respectively, and there was a positive linear correlation between monthly mean air temperature (MT, °C) and MPSM on a cow basis (r=0.763, P=0.004) or a quarter basis (r=0.577, P=0.049), but there were no correlations between MT and MPSM on a cow or a quarter basis (P〉0.05). There was a shift in MPSM trend that the highest MPSM (38.4%) was not for the hottest July with MT at 30.8°C, but for the later September at 27.9°C. The farms need to develop new housing conditions to control cowshed temperatures in the hot season to reduce the mastitis prevalences in the post-hot months. 展开更多

Background Subclinical hypothyroidism (SCH) has recently been acknowledged as an unconventional risk factor for coronary artery disease (CAD) and characterized by poor prognosis, which may be due to atherosclerotic plaque characteristics. We conducted this study to observe coronary plaque characteristics in coronary artery disease patients with concomitant SCH. Methods Patients with coronary artery disease were enrolled in the study and divided into an SCH group (patients, n = 26; plaques, n = 35) and a non-SCH group (patients, n = 52; plaques, n = 66). They were divided 1:2 according to propensity-matched analysis including age, diabetes mellitus, gender, CAD severity and culprit vessel. Optical coherence tomography (OCT) imaging was performed on all patients, and images were analyzed by two inde- pendent investigators. Lipid-rich plaques (LRP), the precursor of vulnerable plaques, were defined as having more than one quadrant occu- pied with lipid pool. Maximum lipid arcs were simultaneously recorded. Fibrotic plaques and calcific plaques were also identified. The pres- ence of coronary dissection, plaque erosion, thrombus, macrophage, calcific nodule, thin-cap fibroatheroma and micro channel were all noted. Results The ratio of LRP in SCH group was significantly higher than that in non-SCH group (54% vs. 30.3%, P = 0.037). That was the case as well for the maximum lipid arcs value (181.5°± 61.6° vs. 142.1° 4± 35.9°, p = 0.046). While thin-cap fibroatheroma (TCFA) was detected, no difference was identified between the two groups in either TCFA ratio (20% vs. 16.7%, P = 0.579) or fibrous cap thickness (57.5 4± 14.0 vs. 63.5 4±10.7 gin, P = 0.319). Other OCT characteristics such as dissection, plaque erosion, thrombus, macrophage shadow and calcific nodule were also similar. ConcLusion Higher ratio of LRP with greater lipid arc in SCH patients may be related to the plaque instability and poor prognosis in CAD patients with SCH. 展开更多

AIM:To evaluate the diagnostic ability of topographic and tomographic indices with Pentacam and Sirius as well as biomechanical parameters with Corvis ST for the detection of clinical and subclinical forms of keratoconus(KCN).METHODS:In this prospective diagnostic test study,70 patients with clinical KCN,79 patients with abnormal findings in topography and tomography maps with no evidence on clinical examination(subclinical KCN),and 68 normal control subjects were enrolled.The accuracy of topographic,tomographic,and biomechanical parameters was evaluated using the area under the receiver operating characteristic curve(AUC)and cross-validation analysis.The Delong method was used for comparing AUCs.RESULTS:In distinguishing KCN from normal,all parameters showed statistically significant differences between the two groups(P<0.001).Indices with the perfect diagnostic ability(AUC≥0.999)were Sirius KCN vertex of back(KVb),Pentacam random forest index(PRFI),Pentacam index of height decentration(IHD),and Corvis integrated tomographic/biomechanical index(TBI).In distinguishing subclinical KCN from normal,Sirius symmetry index of back(SIb;AUC=0.908),Pentacam inferior-superior difference(IS)value(AUC=0.862),PRFI(AUC=0.847),and Corvis TBI(AUC=0.820)performed best.There were no significant differences between the highest AUCs within keratoconic groups(De Long,P>0.05).CONCLUSION:In clinical KCN,all topographic,tomographic,and biomechanical indices have acceptable outcomes in terms of sensitivity and specificity.However,in differentiating subclinical forms of KCN from normal corneas,curvature-based parameters(SIb and IS value)followed by integrated indices(PRFI and TBI)are the most powerful tools for early detection of KCN. 展开更多

INTRODUCTION: Overt hypothyroidism in pregnancy is associated with adverse outcomes, but the effects of subclinical hypothyroidism and isolated hypothyroxinemia on pregnancy outcomes are still controversial. Subclinical hypothyroidism might be associated with preterm delivery, low Apgar score, fetal death and miscarriages and isolated hypothyroxinemia with preterm labor, high birth weight and neurocognitive deficits in children. Other studies show no association with any complications at all. In the present study we tried to estimate whether maternal subclinical hypothyroidism and isolated hypothyroxinemia are associated with complications during pregnancy in our population which represents the pregnant population of Western Greece. METHODS: In a total of 469 pregnant women, third trimester serum was assayed for thyroid-stimulating hormone (TSH) and free thyroxine (free T4). Thyroid hypofunction was defined as 1) subclinical hypothyroidism with TSH levels above 3 mIU/L for the 3rd trimester and normal free T4 and 2) isolated hypothyroxinemia with TSH levels below 3 mIU/L for the 3rd trimester and free T4 below the 5th percentile. The results were associated with birth weight, week of labor, history of miscarriages and demographic characteristics. Patients with thyroid hypofunction were compared with euthyroid patients (TSH and free T4 between normal limits). The results were analyzed with one-way ANOVA and χ2 test. RESULTS: Subclinical hypothyroidism was documented in 10.9% and isolated hypothyroxinemia in 21.7% of pregnant women. Subclinical hypothyroidism was not associated with birth weight, week of labor, or history of miscarriages. On the contrary, hypothyroxinemia was associated with high birth weight (P < 0.05). CONCLUSION: In our study, we did not find a link between subclinical hypothyroidism and adverse pregnancy outcomes. Similarly, hypothyroxinemia was not associated with pregnancy complications. However, it was associated with higher birth weight. Our studies contribute to our understanding, whether or not subclinical hypothyroidism and isolated hypothyroxinemia are associated with pregnancy adverse outcomes and whether treatment and test for hypothyroidism should become routine during pregnancy. 展开更多

Background:Mastitis caused by different pathogens including Streptococcus uberis(S.uberis)is responsible for huge economic losses to the dairy industry.In order to investigate the potential genetic and epigenetic regulatory mecha‑nisms of subclinical mastitis due to S.uberis,the DNA methylome(whole genome DNA methylation sequencing)and transcriptome(RNA sequencing)of milk somatic cells from cows with naturally occurring S.uberis subclinical mastitis and healthy control cows(n=3/group)were studied.Results:Globally,the DNA methylation levels of CpG sites were low in the promoters and first exons but high in inner exons and introns.The DNA methylation levels at the promoter,first exon and first intron regions were nega‑tively correlated with the expression level of genes at a whole‑genome‑wide scale.In general,DNA methylation level was lower in S.uberis‑positive group(SUG)than in the control group(CTG).A total of 174,342 differentially methylated cytosines(DMCs)(FDR<0.05)were identified between SUG and CTG,including 132,237,7412 and 34,693 DMCs in the context of CpG,CHG and CHH(H=A or T or C),respectively.Besides,101,612 methylation haplotype blocks(MHBs)were identified,including 451 MHBs that were significantly different(dMHB)between the two groups.A total of 2130 differentially expressed(DE)genes(1378 with up‑regulated and 752 with down‑regulated expression)were found in SUG.Integration of methylome and transcriptome data with MethGET program revealed 1623 genes with signifi‑cant changes in their methylation levels and/or gene expression changes(MetGDE genes,MethGET P‑value<0.001).Functional enrichment of genes harboring≥15 DMCs,DE genes and MetGDE genes suggest significant involvement of DNA methylation changes in the regulation of the host immune response to S.uberis infection,especially cytokine activities.Furthermore,discriminant correlation analysis with DIABLO method identified 26 candidate biomarkers,including 6 DE genes,15 CpG‑DMCs and 5 dMHBs that discriminated between SUG and CTG.Conclusion:The integration of methylome and transcriptome of milk somatic cells suggests the possible involve‑ment of DNA methylation changes in the regulation of the host immune response to subclinical mastitis due to S.uberis.The presented genetic and epigenetic biomarkers could contribute to the design of management strategies of subclinical mastitis and breeding for mastitis resistance. 展开更多

Although low testosterone levels in men have been associated with high risk for cardiovascular disease, little is known about the association between male sex hormones and subclinical coronary disease in men with apparently low cardiometabolic risk. This study was performed to investigate the association between male sex hormones and subclinical coronary artery calcification measured as coronary calcium score in non-obese Korean men. We examined the relationship of total testosterone, sex hormone-binding globulin, bioavai lable testosterone and free testosterone with coronary calcium score in 291 non-obese Korean men (mean age: 52.8--- 9.3 years) not having a history of cardiovascular disease. Using multiple linear regression, we evaluated associations between log (sex hormone) levels and log (coronary calcium score) after adjusting for confounding variables in 105 men with some degree of coronary calcification defined as coronary calcium score ~〉 1. In multiple linear regression analysis, bioavailable testosterone was inversely associated with coronary calcium score (P=0.046) after adjusting for age, body mass index, smoking status, alcohol consumption, regular exercise, mean blood pressure, resting heart rate, C-reactive protein, fasting plasma glucose, total cholesterol, triglyceride, high-density lipoprotein (HDL) cholesterol, hypertension medication and hyperlipidernia medication, whereas total testosterone, sex hormone-binding globulin and free testosterone were not (P=0.674, P=O. 121 and P=O. 102, respectively). Our findings indicate that bioavailable testosterone is inversely associated with the degree of subclinical coronary artery calcification in non-obese men. 展开更多

Objective Ideal cardiovascular health(CVH) could predict a lower risk of developing cardiovascular diseases. This study was conducted to investigate the association between ideal CVH and subclinical atherosclerosis in a population cohort of Chinese adults aged ≥ 40 years. Methods This study was designed as a cross-sectional analysis of 8,395 participants who had complete data at baseline and a prospective analysis of 4,879 participants who had complete data at 4.3 years of follow-up. Ideal CVH metrics were defined according to the American Heart Association. Subclinical atherosclerosis was evaluated by plaques in carotid arteries, carotid intima-media thickness(CIMT), brachial-ankle pulse wave velocity(baPWV), and urinary albumin-to-creatinine ratio(UACR). Results Both the prevalence and incidence of atherosclerosis measures were found to be decreased with increasing numbers of ideal CVH metrics at baseline(all P values for trend < 0.01). The levels of CIMT and UACR at follow-up showed an inverse and significant association with the numbers of ideal CVH metrics at baseline(both P values for trend < 0.05) but a borderline significant association with baPWV(P for trend = 0.0505). Taking participants with 0-1 ideal metric as reference, we found that participants with 5-6 ideal metrics had significantly lower risks of developing carotid plaques(odds ratio, OR = 0.46; 95% confidence interval, CI 0.27-0.79), increased CIMT(OR = 0.60; 95% CI 0.42-0.84), and increased baPWV(OR = 0.57; 95% CI 0.34-0.97) after full adjustments. A significant interactive effect of age and CVH was detected on CIMT and baPWV progression(both P values for interaction < 0.05). Conclusion The numbers of ideal CVH metrics showed a significant and inverse association with the risk of developing subclinical atherosclerosis in middle-aged and elderly Chinese adults, whereas its dose-response effect was attenuated in individuals aged ≥ 60 years and partially weakened in male participants. 展开更多

Subclinical varicocele represents an abnormality of veins of the pampiniform plexus on scrotal ultrasound(US)without a clinically palpable varicocele.Its significance remains unclear.While guidelines do not recommend surgical intervention,clinical management is variable.As there is limited information on long-term outcome of subclinical varicoceles due to challenges in diagnosis and management,we performed a single-institution,retrospective review of patients from October 1999 to October 2014 with subclinical varicocele and with available US studies reviewed by a single radiologist.Subclinical varicocele was defined as dilation of the pampiniform venous plexus on US involving≥2 vessels with diameter>2.5 mm,without clinical varicocele on physical examination or prior inguinal surgery.Thirty-six of 98 patients identified were confirmed as having a subclinical varicocele and analyzed.The mean age at initial visit was 15.5 years,with a mean follow-up of 26.5 months.The majority were right-sided(69.4%,n=25),usually with a contralateral clinical varicocele.Testicular asymmetry(>20%volume difference of the affected side by testicular atrophy index formula)was assessed in 9 patients with unilateral subclinical varicocele without contralateral clinical or subclinical varicocele and observed in 1 patient.Of 17 patients with follow-up,3(17.6%)progressed to clinical varicocele without asymmetric testicular volume,as most remained subclinical or resolved without surgery.In our experience,subclinical varicoceles appeared unlikely to progress to clinical varicoceles,to affect testicular volume,or to lead to surgery.Although our study is limited in numbers and follow-up,this information may aid clinical management strategies and guide future prospective studies. 展开更多

Background:Atherosclerosis forms the pathological basis for the development of cardiovascular disease.Since pathological processes initially develop without clinically relevant symptoms,the identification of early markers in the subclinical stage plays an important role for initiating early interventions.There is evidence that regulatory T cells(Tregs)are involved in the development of atherosclerosis.Therefore,the present study aimed to identify and investigate associations with Tregs and their subsets in a cohort of healthy elderly individuals with and without subclinical atherosclerotic plaques(SAP).In addition,various lifestyle and risk factors,such as cardiorespiratory fitness,were investigated as associated signatures.Methods:A cross-sectional study was performed in 79 participants(male:n=50;age=63.6±3.7 years;body mass index=24.9±3.1 kg/m2;mean±SD)who had no previous diagnosis of chronic disease and were not taking medication.Ultrasound of the carotids to identify SAP,cardiovascular function measurement for vascular assessment and a cardiorespiratory fitness test to determine peak oxygen uptake were performed.Additionally,tests were conducted to assess blood lipids and determine glucose levels.Immunophenotyping of Tregs and their subtypes(resting(rTregs)and effector/memory(mTregs))was performed by 8-chanel flow cytometry.Participants were categorized according to atherosclerotic plaque status.Linear and logistic regression models were used to analyze associations between parameters.Results:SAP was detected in a total of 29 participants.The participants with plaque were older(64.8±3.6 years vs.62.9±3.5 years)and had higher peripheral systolic blood pressure(133.8±14.7 mmHg vs.125.8±10.9 mmHg).The participants with SAP were characterized by a lower percentage of rTregs(28.8%±10.7%vs.34.6%±10.7%)and a higher percentage of mTregs(40.3%±14.7%vs.30.0%±11.9%).Multiple logistic regression identified age(odds ratio(OR)=1.20(95%confidence interval(95%CI):1.011.42))and mTregs(OR=1.05(95%CI:1.021.10))as independent risk factors for SAP.Stepwise linear regression could reveal an association of peak oxygen uptake(β=0.441),low-density lipoprotein(LDL)(β=0.096),and SAP(β=6.733)with mTregs and LDL(β=0.104)with rTregs.Conclusion:While at an early stage of SAP,the total proportion of Tregs gives no indication of vascular changes,this is indicated by a shift in the Treg subgroups.Factors such as serum LDL or cardiopulmonary fitness may be associated with this shift and may also be additional diagnostic indicators.This could be used to initiate lifestyle-based preventive measures at an early stage,which may have a protective effect against disease progression. 展开更多

BACKGROUND Adrenal incidentaloma(AI)has been frequently encountered in the clinical setting.It has been shown that primary aldosteronism(PA)or subclinical Cushing’s syndrome(SCS)are the representative causative diseases of AI.However,the coexistence of PA and SCS has been reportedly observed.Recently,we encountered a case of AI,in which PA and SCS coexisted,confirmed by histopathological examinations after a laparoscopic adrenalectomy.We believe that there were some clinical implications in the diagnosis of the present case.CASE SUMMARY A 58-year-old man presented with lower right abdominal pain with a blood pressure of 170/100 mmHg.A subsequent computed tomography scan revealed right ureterolithiasis,which was the cause of right abdominal pain,and right AI measuring 22 mm×25 mm.After the disappearance of right abdominal pain,subsequent endocrinological examinations were performed.Aldosterone-related evaluations,including adrenal venous sampling,revealed the presence of bilateral PA.In addition,several cortisol-related evaluations showed the presence of SCS on the right adrenal adenoma.A laparoscopic right adrenalectomy was then performed.The histopathological examination of the resected right adrenal revealed the presence of a cortisol-producing adenoma,while CYP11B2 immunoreactivity was absent in this adenoma.However,in the adjacent nonneoplastic adrenal,multiple CYP11B2-positive adrenocortical micronodules were detected,showing the presence of aldosterone-producing adrenocortical micronodules.CONCLUSION Careful clinical and pathological examination should be performed when a patient harboring AI presents with concomitant SCS and PA. 展开更多

During the Yushu Earthquake on April 14,2010,a high incidence of acute high altitude illness was observed in the mountain rescuers,and 0.73 % of these patients suffered from high altitude pulmonary edema,of which 12 patients developed subclinical pulmonary edema and concomitantly contracted acute mountain sickness. Symptoms and signs were atypically high heart rate with high respiratory rate,striking cyanosis,and significantly low oxygen saturation,whereas no moist rates were heard on auscultation,and Chest X-ray showed peripheral with a patchy distribution of mottled infiltrations in one or both lung fields. We believe that subclinical high altitude pulmonary edema is an earliest stage of pulmonary edema at high altitude. The possible pathogenesis and the diagnosis were discussed. 展开更多

In order to study the correlation of different degrees of subclinical mastitis and cytokines,the changes of interleukin-1β(IL-1β),interleukin-6(IL-6),interleukin-8(IL-8)and tumor necrosis factor-α(TNF-α)in blood and milk and whether the changes of these indexes were caused by mastitis were analyzed.The 40 Holstein cows in lactation period were tested and grouped by somatic cell count(SCC)method in milk:Group C(SCC<5×10~5 cells·mL^(-1)),Group I(5×10~5 cells·mL^(-1)5×10~6 cells·mL^(-1)).The contents of IL-1β,IL-6,IL-8 and TNF-αwere analyzed by radioimmunoassay.The results showed that the contents of IL-6,IL-8 and TNF-αin the blood and milk of different degrees of subclinical mastitis increased with the severity of mastitis,and were higher than those in normal group.The contents of IL-6,IL-8 and TNF-αin serum and whey of dairy cows affected by different degrees of subclinical mastitis were higher than those in normal group(Group C).The content of IL-1βincreased and decreased with the increase of inflammation,and it did not have the value of evaluating mastitis.In conclusion,the severities of cow subclinical mastitis and the contents of cytokines were positive correlations.These indexes could be used as the basis for judging mammary gland injury. 展开更多

BACKGROUND Lithium carbonate is used to manage various mood disorders,but it can cause thyroid abnormalities,including goiter,hypothyroidism,and hyperthyroidism.In rare cases,it can lead to giant goiter and subclinical hyperthyroidism,which may require surgical intervention in severe cases.CASE SUMMARY This case represents a rare development of giant goiter and subclinical hyperthyroidism in a schizophrenia patient who was subjected to prolonged lithium carbonate treatment.The enlarged thyroid gland caused pressure on the airway and recurrent laryngeal nerve,which led to respiratory distress,hoarseness,and dysphagia.The immediate danger of suffocation required urgent surgical intervention.In this report,we describe the case of a 41-year-old Chinese woman.This sheds light on the etiology and challenges associated with managing a giant goiter.The patient underwent a subtotal thyroidectomy to relieve airway compression and facilitate airway expansion.Prior to the procedure,the patient was given iodine to prepare.Concurrently,changes were made to the psychiatric medication regimen.Following surgery,the patient's respiratory function and vocal cord functionality improved significantly,and her mental state remained stable.CONCLUSION It is essential to monitor thyroid function,test thyroid antibody levels,and perform thyroid ultrasounds consistently in all patients undergoing long-term lithium carbonate treatment.This vigilance helps prevent severe and potentially life-threatening thyroid enlargement. 展开更多
