Background::Whether functional gastrointestinal disorders (FGIDs) are associated with the long-term risk of chronic kidney disease (CKD) remains unclear. We aimed to investigate the prospective association of FGIDs with CKD and examine whether mental health mediated the association.Methods::About 416,258 participants without a prior CKD diagnosis enrolled in the UK Biobank between 2006 and 2010 were included. Participants with FGIDs (including irritable bowel syndrome [IBS], dyspepsia, and other functional intestinal disorders [FIDs; mainly composed of constipation]) were the exposure group, and non-FGID participants were the non-exposure group. The primary outcome was incident CKD, ascertained from hospital admission and death registry records. A Cox proportional hazard regression model was used to investigate the association between FGIDs and CKD, and the mediation analysis was performed to investigate the mediation proportions of mental health.Results::At baseline, 33,156 (8.0%) participants were diagnosed with FGIDs, including 21,060 (5.1%), 8262 (2.0%), and 6437 (1.6%) cases of IBS, dyspepsia, and other FIDs, respectively. During a mean follow-up period of 12.1 years, 11,001 (2.6%) participants developed CKD. FGIDs were significantly associated with a higher risk of incident CKD compared to the absence of FGIDs (hazard ratio [HR], 1.36; 95% confidence interval [CI], 1.28–1.44). Similar results were observed for IBS (HR, 1.27; 95% CI, 1.17–1.38), dyspepsia (HR, 1.30; 95% CI, 1.17–1.44), and other FIDs (HR, 1.60; 95% CI, 1.43–1.79). Mediation analyses suggested that the mental health score significantly mediated 9.05% of the association of FGIDs with incident CKD and 5.63–13.97% of the associations of FGID subtypes with CKD. Specifically, the positive associations of FGIDs and FGID subtypes with CKD were more pronounced in participants with a high genetic risk of CKD.Conclusion::Participants with FGIDs had a higher risk of incident CKD, which was partly explained by mental health scores and was more pronounced in those with high genetic susceptibility to CKD.

OBJECTIVES: This study aims to explore the therapeutic targets of curcumin in periodontitis through network pharmacology and molecular docking technology. METHODS: Targets of curcumin and periodontitis were predicted by different databases, and the protein-protein interaction (PPI) network constructed by String revealed the interaction between curcumin and periodontitis. The key target genes were screened for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. Molecular docking was performed to analyze the binding potential of curcumin to periodontitis. RESULTS: A total of 672 periodontitis-related disease targets and 107 curcumin-acting targets were obtained from the databases, and 20 key targets were screened. The GO and KEGG analyses of the 20 targets showed that curcumin might play a therapeutic role through the hypoxia-inducible factor (HIF)-1 and parathyroid hormone (PTH) signaling pathways. Molecular docking analysis showed that curcumin had good binding potential with multiple targets. CONCLUSIONS The potential key targets and molecular mechanisms of curcumin in treating periodontitis provide a theoretical basis for new drug development and clinical applications.

We aimed to investigate the relationship of dietary zinc intake with new-onset hypertension among Chinese adults. A total of 12,177 participants who were free of hypertension at baseline from the China Health and Nutrition Survey were included. Dietary intake was assessed by three consecutive 24-h dietary recalls combined with a household food inventory. Participants with systolic blood pressure ≽ 140 mmHg or diastolic blood pressure ≽ 90 mmHg or diagnosed by a physician or under antihypertensive treatment during the follow-up were defined as having new-onset hypertension. During a median follow-up duration of 6.1 years, 4269 participants developed new-onset hypertension. Overall, the association between dietary zinc intake and new-onset hypertension followed a J-shape (P for non-linearity < 0.001). The risk of new-onset hypertension significantly decreased with the increment of dietary zinc intake (per mg/day: hazard ratio (HR) 0.93; 95% confidence interval (CI) 0.88-0.98) in participants with zinc intake < 10.9 mg/day, and increased with the increment of zinc intake (per mg/day: HR 1.14; 95% CI 1.11-1.16) in participants with zinc intake ≽ 10.9 mg/day. In conclusion, there was a J-shaped association between dietary zinc intake and new-onset hypertension in general Chinese adults, with an inflection point at about 10.9 mg/day.

Objective:To investigate the differences of white matter diffusion properties between vulnerable and resistant individuals to continuous attention after sleep deprivation.Methods:According to the psychomotor vigilance test performance before and after sleep deprivation, the participants were divided into the vulnerable group( n=24) and resistant group( n=25). All participants underwent diffusion tensor imaging (DTI) scans.Tract based spatial statistics(TBSS) was used to compare fractional anisotropy(FA), mean diffusivity(MD), axial diffusivity(AD), radial diffusivity(RD) maps between the two groups.Spearman correlation analysis was conducted by SPSS 24.0 to investigate the relationships between the altered DTI metrics and PVT task performance. Results:(1) Compared with resistant group, FA value of vulnerable group decreased in the body of corpus callosum(x, y, z=-8, 9, 25, t=-7.855), right superior longitudinal fasciculus(x, y, z=-39, -7, 26, t=-6.252), bilateral anterior limb of internal capsule(x, y, z=-13, 8, 13, t=-5.235; x, y, z=12, 8, 3, t=-5.024) and right posterior thalamic radiation(x, y, z=-26, -56, 17, t=-5.469)(TFCE corrected, P<0.05, cluster size≥50 voxel). (2) Compared with resistant group, MD value of vulnerable group increased in the body of corpus callosum(x, y, z=-3, -6, 26, t=7.613), right superior longitudinal fasciculus(x, y, z=-31, -19, 38, t=5.314), bilateral anterior limb of internal capsule(x, y, z=-16, 7, 8, t=6.898; x, y, z=15, 5, 7, t=6.652), splenium of corpus callosum(x, y, z=27, -53, 17, t=6.541), and AD value increased in the right superior longitudinal fasciculus(x, y, z=-33, -19, 39, t=4.892), splenium of corpus callosum(x, y, z=-22, -49, 21, t=5.450), genu of corpus callosum(x, y, z=4, 26, 0, t=4.332), as well as RD value increased in the right superior corona radiata(x, y, z=-17, 1, 33, t=7.558), body of corpus callosum(x, y, z=4, -8, 26, t=6.699), right anterior limb of internal capsule(x, y, z=-12, 7, 3, t=5.212) (TFCE corrected, P<0.05, cluster size≥50 voxel). (3) Correlational analysis revealed that the negative correlations were found between PVT task performance and the FA value in the right superior longitudinal fasciculus( r=-0.492, P<0.001), right anterior limb of internal capsule( r=-0.510, P<0.001), right posterior thalamic radiation( r=-0.502, P<0.001) and body of corpus callosum( r=-0.464, P<0.001). The positive correlations were found between PVT task performance and the MD value in the body of corpus callosum( r=0.500, P<0.001), right superior longitudinal fasciculus( r=0.499, P<0.001), splenium of corpus callosum( r=0.462, P<0.001), right anterior limb of internal capsule( r=0.471, P<0.001), and AD value in right superior longitudinal fasciculus( r=0.643, P<0.001), as well as RD value in right superior corona radiate( r=0.498, P<0.001) (Bonferroni corrected, P<0.003). Conclusion:Differences in the microstructural characteristics of white matter fiber tracts in specific brain regions may constitute the potential neuropathological basis for the phenotypes of vulnerable and resistant individuals to continuous attention after sleep deprivation.

Objective:To investigate the effect of thrombus burden on the clinical outcome of endovascular recanalization in large vessel occlusive stroke.Methods:Patients with acute anterior circulation occlusion who underwent endovascular treatment within 24 hours after onset in Zhengzhou University People′s Hospital from January 2018 to December 2019 were retrospectively collected. According to the clot burden score (CBS) of DSA, total objectives were divided into CBS≥6 group (24 cases) and CBS<6 group (38 cases). Clinical data of the two groups were collected and the modified Rankin scale (mRS) was used to evaluate the clinical outcome at 90 days after surgery. Independent sample t-test, Wilcoxon rank sum test and χ 2 test were used to compare the clinical data between the two groups. Independent risk factors affecting the clinical outcome were analyzed by binary logistic regression. Results:There were no statistically significant differences in basic demographic data, stroke risk factors and other factors between the CBS≥6 group and CBS<6 group ( P>0.05).The proportion of using tirofiban after surgery in the CBS≥6 group (63.2%, 24/38) was lower than that in the CBS<6 group (87.5%, 21/24) (χ2=4.380, P=0.044). The discharge NIHSS score of the CBS≥6 group was [5.0 (3.3, 7.8) points] lower than CBS<6 group [8.5 (1.8, 14.5) points] ( Z=5.221, P=0.022). The proportion of postoperative mRS 0-2 was (91.7%, 22/24) in the CBS≥6 group higher than CBS<6 group(39.5%, 15/38) (χ2=20.486, P=0.001), there were no statistically significant differences between the two groups ( P<0.05). The results of binary logistics regression analysis showed the CBS groups (OR=0.042, 95%CI 0.007-0.244 , P=0.001) was an independent risk factor affecting good outcome. Subgroup analysis of whether tirofiban was used or not showed there was no statistically significant difference in clinical prognosis between the two groups ( P>0.05). Conclusions:The clinical outcome of CBS≥6 group is significantly better than that of CBS<6 group, and patients with small thrombus burden are more likely to get a good clinical outcome of 90 days.

Objective:This study compares the magnetic resonance imaging (MRI) appearance of two types of breast tissue markers to investigate the appropriate clinical application of the markers.Methods:Breast MRI of 69 patients (78 masses) with breast tissue markers had been placed were analyzed retrospectively from November 2015 to August 2018 in our hospital. The sizes and shapes of breast tissue markers were assessed in axial fat-suppressed T2-weighted images, T1-weighted images and contrast-enhanced T1-weighed images.Results:The length of the coil nickel-free stainless steel markers were greater than ribbon titanium markers, with statistical difference in fat-suppressed T2-weighted images ( P=0.039). In contrast-enhanced T1-weighted images, all coil nickel-free stainless steel markers showed >6 mm diameter and round shape, and ribbon titanium markers showed >6 mm diameter ( n=20) or ≤6 mm diameter ( n=8), and round ( n=20), dot ( n=7) or band ( n=1) shapes. The categories of sizes and shapes in two types of breast tissue markers both had statistical significance ( P<0.001, P<0.001). Conclusions:Small breast lesions with breast tissue markers are not suitable for MRI evaluation. The artifact of ribbon titanium markers is smaller than coil nickel-free stainless steel markers, so they have less impact for lesions. The choice of the breast tissue markers and image evaluation methods should depend on the different clinical conditions.

Objective:To investigate the safety and efficacy of endovascular treatment in acute anterior circulation massive cerebral infarction and its prognostic factors.Methods:A retrospective analysis was performed on clinical data of 34 patients with acute anterior circulatory massive cerebral infarction who received intravascular treatment in our hospital from February 2018 to December 2019. The perioperative hemorrhage rate and mortality rate were analyzed in these patients. Modified Rankin scale (mRS) scores were taken as the evaluation standard in the prognoses of these patients during the 90 d of follow up, and the influencing factors affecting the prognoses of patients with massive cerebral infarction were analyzed.Results:The operation was successful in 30 patients (88.2%); the operation time was (97.41±54.58) min, and the number of thrombolysis was (1.91±0.75) times. Distal embolization occurred in 4 patients (11.8%); there were 3 patients with non-symptomatic hemorrhage (8.8%) and 3 patients with symptomatic hemorrhage (8.8%). Cerebral hernia occurred in 7 patients (20.6%); there were 5 deaths (14.4%). During the 90 d of follow up, 13 patients (38.2%) had good prognosis, and 21 (61.8%) had poor prognosis; there were statistically significant differences in NIHSS scores at admission, infarction locations in diffusion weighted imaging, vascular occlusion locations in DSA, pecentages of patients accepted preoperative intravenous thrombolysis and patients with cerebral hernia between the two groups ( P<0.05). NIHSS scores at admission ( OR=0.817, 95% CI: 0.682-0.980, P=0.029), thrombus load scale scores ( OR=5.981, 95%CI: 1.827-19.575, P=0.003), vascular occlusion locations in DSA ( OR=0.031, 95% CI: 0.003-0.311, P=0.003) and pecentage of patients accepted preoperative intravenous thrombolysis ( OR=0.092, 95% CI: 0.010-0.838, P=0.034) were independent factors influencing the prognoses of emergency intravascular treatment. Conclusions:Endovascular recanalization can achieve a relatively good prognosis in patients with massive cerebral infarction. Patients with low NIHSS scores, high thrombotic load scale scores, and middle cerebral artery occlusion, and patients accepted direct intravascular treatment have relatively good prognosis.

OBJECTIVETo explore the value of detecting podocalyxin (PCX) level in urinary extracellular vesicles for the diagnosis of diabetic nephropathy.

METHODSThis study was conducted among 57 diabetic patients admitted during the period from March to September, 2017, including 34 with uncomplicated diabetics and 23 with diabetic nephropathy; 21 patients with other types of nephropathy and 11 healthy individuals were also included to serve as the controls. Transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA) were used to verify the separation of urinary extracellular vesicles. The molecular markers of extracellular vesicles (TSG101 and podocalyxin [PCX]) were detected using Western blotting. PCX levels in extracellular vesicles were also detected using ELISA.

RESULTSTEM reveal the presence of numerous extracellular vesicles in the urine with intact morphology and different sizes, and most of them were below 300 nm in diameter as shown by NTA. TSG101 expression was detected in the samples from all the 4 groups. Positive expression of PCX was detected in the samples from patients with diabetic nephropathy but not in the other groups. In patients with diabetic nephropathy, the mean PCX levels (3.27±2.30 ng/μmol)was significantly higher than those in the healthy control group (1.22±0.36 ng/μmol), uncomplicated diabetes group (2.22±1.29 ng/μmol) and nephropathy group (1.24±0.45 ng/μmol).

CONCLUSIONSPCX level in urinary extracellular vesicles is significantly increased in patients with diabetic nephropathy, suggesting the value of PCX as a potential marker for clinical diagnosis of diabetic nephropathy.

Objective To investigate the safety of endovascular thrombectomy in acute ischemic stroke patients with pre-existing intracranial aneurysms. Methods Seven patients with acute ischemic stroke combined with intracranial aneurysms, admitted to and received endovascular treatment in our hospital from January 2014 to December 2016, were chosen. The clinical data and safety were analyzed retrospectively.
