Objective To investigate the clinical manifestation and imaging features of diabetic striatopathy(DS).Methods A retrospective analysis was conducted on the clinical,laboratory,and imaging data of 8 patients with DS,which was then summarized in conjunction with relevant literature.Results Random blood glucose(8.39-24.80 mmol/L)and glycated hemoglobin(HbA1c)(9.0%-21.50%)were elevated in 8 patients.One case had positive urine ketone bodies(++),while 7 cases had negative urine ketone bodies(-).Hemichorea was present in 7 cases,while 1 case did not exhibit hemichorea.A total of 7 cases showed unilateral striatum T1WI hyperintensity on MRI,and 8 cases showed iso/hyper-density on CT scans.Following blood glucose control and other related treatments,involuntary movement disappeared in 2 cases,and symptoms improved in 5 cases.Conclusion DS mainly occurs in diabetic patients with poorly controlled blood glucose,presenting with typical clinical manifestation and neuroimaging features.It manifests exclusively in the contralateral striatum of the affected limb.The diagnosis should be based on a combination of clinical,laboratory,and imaging findings to prevent missed or misdiagnoses.

Objective To explore the value of intravoxel incoherent motion(IVIM)parameters in the diagnosis of ipsilateral thalamic diaschisis(ITD)after unilateral supratentorial cerebral infarction via combination of arterial spin labeling(ASL)and IVIM.Methods A total of 111 patients with cerebral infarction were selected,including 61 patients in the acute stage(＞6 h-3 d),50 patients in the subacute stage(＞3 d-11 d).All patients were subjected to MRI examination,and the diffusion weighted imaging(DWI),ASL,and IVIM image data were uploaded to the GE workstation.The regions of interest(ROI)in the bilateral thalamus were selected,and the cerebral blood flow(CBF),D*,D,and f values were measured,and the asymmetry index(AI)was calculated.ITD was diagnosed according to AI＞10％,and all patients were divided into ITD-positive and ITD-negative groups.The differences of each parameter between the two groups and their relationship with AI were analyzed.Results In acute stage and subacute stage cerebral infarction,the CBF,D*and D values of ipsilateral thalamus were lower than those of contralateral thalamus,while the f value was higher than those of contralateral thalamus.There was no statistical significance in D*,D and f values between ITD-positive and ITD-negative groups after acute stage cerebral infarction(P＞0.05).There were significant differences in CBF,apparent diffusion coefficient(ADC),D and f values in ITD-positive group after subacute stage cerebral infarction(P＜0.05),but no significant differences in D*value of ITD-positive group and CBF,D*,D,f values of ITD-negative group(P＞0.05).AI-D*,AI-D and AI-ADC in subacute stage were positively correlated with AI-CBF,while AI-f was negatively correlated with AI-CBF.The area under the curve(AUC)of AI-D and AI-f in subacute stage were 0.749 and 0.699,respectively.Conclusion The combination of ASL and IVIM has confirmed the phenomenon of ITD after unilateral supratentorial cerebral infarction,with high diagnostic efficacy of quantitative parameters D value and f value.It can non-invasively evaluate the thalamic microstructural and perfusion changes in the early stage after cerebral infarction.

Objectives:To verify the reliability and validity of the frailty assessment scale for elderly patients with inguinal hernia and to evaluate the value of its clinical application.Methods:A convenience sampling method was used to collect 129 geriatric patients who underwent inguinal hernia surgery from January 2018 to January 2023 in nine hospitals in Liaoning Province. There were 120 males and 9 females, of whom 89 patients were 60 to <75 years old, 33 patients were 75 to <85 years old and 7 patients were ≥85 years old. The 129 patients included 11 elderly patients with inguinal hernia who had recovered from preoperative infection with COVID-19. Statistical methods such as Cronbach′s coefficient, Kaiser-Meyer-Olkin test, Bartlett′s test, Pearson′s correlation analysis, etc. were calculated to verify the reliability indexes such as feasibility, content validity, structural validity, criterion-related validity, internal consistency reliability, and re-test reliability. Taking the 5-item modified frailty index (5-mFI) as the gold standard, the area under the curve was used to analyze the ability of the two scales to predict the occurrence of postoperative acute urinary retention, postoperative delirium, poor incision healing, operative hematoma seroma, and postoperative complications.Results:The frailty assessment scale for elderly patients with inguinal hernia showed good reliability and validity (valid completion rate of 99.2%; item content validity index of 1.000, and the scale content validity index of 1.000; exploratory factor analysis extracted a total of 1 principal component, and factor loadings of each item of 0.565 to 0.873; the AUC for frailty diagnosis using 5-mFI as the gold standard of 0.795 ( P<0.01) Cronbach′s coefficient of 0.916, retest reliability coefficient of 0.926), it could effectively predict postoperative acute urinary retention, delirium, hematoma seroma in the operative area and total complications (AUC of 0.746, 0.870, 0.806, and 0.738, respectively; all P<0.05), and prediction efficiency was higher than that of 5-mFI (AUC of 0.694, 0.838, 0.626 and 0.641, P<0.05 for delirium only), but both scales were inaccurate in predicting poor incision healing (AUC of 0.519, P=0.913 for the frailty assessment scale and 0.455, P=0.791 for the 5-mFI). Conclusions:The frailty assessment scale for elderly patients with inguinal hernia is reliable and significantly predicts the occurrence of postoperative adverse events in elderly inguinal hernia patients. The scale can also be used for preoperative frailty assessment in elderly patients with inguinal hernia after rehabilitation from COVID-19 infection.

Gene Ontology(GO)has been widely used to annotate functions of genes and gene prod-ucts.Here,we proposed a new method,TripletGO,to deduce GO terms of protein-coding and non-coding genes,through the integration of four complementary pipelines built on transcript expression profile,genetic sequence alignment,protein sequence alignment,and naive probability.TripletGO was tested on a large set of 5754 genes from 8 species(human,mouse,Arabidopsis,rat,fly,budding yeast,fission yeast,and nematoda)and 2433 proteins with available expression data from the third Critical Assessment of Protein Function Annotation challenge(CAFA3).Experimental results show that TripletGO achieves function annotation accuracy significantly beyond the current state-of-the-art approaches.Detailed analyses show that the major advantage of TripletGO lies in the coupling of a new triplet network-based profiling method with the feature space mapping technique,which can accurately recognize function patterns from transcript expression profiles.Meanwhile,the combination of multiple complementary models,especially those from transcript expression and protein-level alignments,improves the coverage and accuracy of the final GO anno-tation results.The standalone package and an online server of TripletGO are freely available at https://zhanggroup.org/TripletGO/.

Objective:To explore the application values of arterial transit artifact (ATA) showed by 3D arterial spin labeling (3D-ASL) combined with hyperintense vessel sign (HVS) showed by T2-magnetic resonance fluid attenuation inversion recovery (T2-FLAIR) in evaluating collateral circulation and clinical prognoses in patients with acute ischemic stroke (AIS).Methods:One hundred and one AIS patients admitted to our hospital from September 2017 to November 2019 were included in the study. According to the degrees of vascular stenosis, these patients were divided into middle cerebral artery (MCA) positive group (stenosis degree≥50%, n=60) and MCA negative group (stenosis degree<50%, n=41); according to whether there was ATA, the MCA-positive patients were divided into ATA(+) group ( n=33) and ATA(-) group ( n=27). The cerebral blood flow (CBF) of the ischemic penumbra (IP) and National Institute of Health stroke scale (NIHSS) scores at admission and at discharge in patients from different groups were recorded; the relative CBF (rCBF) and drop degrees of NIHSS scores at discharge were calculated; a comparative analysis of the relations of ATA and HVS with clinical prognoses was performed. Results:There were significant differences in HVS grading, rCBF, NIHSS scores at admission and at discharge and drop degrees of NIHSS scores at discharge between MCA positive group and MCA negative group ( P<0.05). Among the 60 patients from MCA-positive group, 16 were classified as HVS grading 0, 14 as HVS grading I, 17 as HVS grading II, and 13 as HVS grading III; there were statistical differences in rCBF and drop degrees of NIHSS scores at discharge among patients with different HVS grading ( P<0.05); the higher the HVS grading was, the greater the decrease of rCBF and drop degrees of NIHSS scores were. Spearman correlation analysis showed that there was a high positive correlation between HVS grading and rCBF ( r s=0.808, P=0.000), and a moderate positive correlation between HVS grading and drop degrees of NIHSS scores at discharge ( r s=0.737, P=0.000). Patients in the ATA(+) group had significantly greater decrease of rCBF and drop degrees of NIHSS scores, and significantly lower NIHSS scores at discharge as compared with patients from the ATA(-) group ( P<0.05). Spearman correlation analysis showed that ATA had moderate positive correlations with rCBF and drop degrees of NIHSS scores ( r s=0.403, P=0.001; r s=0.550, P=0.000); there was a highly positive correlation between rCBF and drop degrees of NIHSS scores ( r s=0.827, P=0.000). Receiver operating characteristic curve showed that the sensitivities of ATA and HVS to assess cerebral blood perfusion changes were 83.3% and 66.7%, and the specificities were 52.1% and 89.6%, respectively; the combined sensitivity of the two was 83.3% and the specificity was 64.6%. Conclusion:HVS combined with ATA can effectively evaluate the perfusion in IP region and prognoses of AIS patients.

Objective To explore the application value of 3.0T MR diffusion tensor imaging (DTI)in 3D reconstruction of the knee peripheral nerve.Methods DTI with 25 motion probing gradients (MPGs)was performed on the left knee in 22 healthy young volunteers;By choosing the original images scaned in the vertical direction,three post-processing methods including maximum intensity proj ection (MIP),volume rendering (VR)and diffusion tensor tractography (DTT)were used.Two radiologists evaluated these images visually.For the same nerve,MIP,VR and DTT were compared using Friedman test.Intraclass correlation coefficient (ICC )analysis was used to compare the correlation among the three imaging methods.Score consistency between two observers was calculated by using the Kappa statistic.Results For the same nerve,there was no significant statistical difference for the MIP,VR and DTT imaging quality scores(P>0.05).The I CC value and the k value were 0.718-0.856,0.668-0.705,respectively.Conclusion Stereoscopic and clear displaying the tibial nerve/the common peroneal nerve in the knee can be achieved by using MIP,VR and DTT post-processing methods based on DTI original images.The reconstruction of MIP,VR is simple and efficient,in which the objectivity is better than DTT.The reconstruction of MIP,VR can be used as effective preview methods before the DTT reconstruction with complexity and strong subjective dependence.
