ObjectiveTo assess revascularization and vessel anastomosis in digital replantations with DSA.MethodsTwelve cases of digital replantations underwent digital subtract angiography during 2 to 4 days after fingers reattachment. The vessel anastomosis,hemodynamics,stenosis and discontinuation were investigated.The unobstructed and smooth anastomosis was suggested as early stage survival of the reattached fingers,the spasm and stenosis of the reattached vessels were considered as mild vascular crisis,and the discontinuation of hemodynamics were indicated as severe vascular crisis.ResultsThe total 27 vessels were clearly displayed on DSA.Of these vessels,23 vessels were unobstructed and smooth,all digits were survived.Diagnosis coincidence of early stage survival was 100%(23/23). Two vessels were obstructed,which were testified having thrombus by operation research.The other 2 vessels were spasm,the digits were also survived ultimately by expectant treatment.All 4 abnormal vessel anatomosis were found by DSA.Conclusion DSA is important modality in assessing revascularization and blood circulation for digital replantations,guiding in dealing with the vascular crisis,and in predicting early stage survival of the reattached digits.

Sine oculis homeobox 1 (Six1) is an important factor for embryonic development and carcinoma malignancy. However, the localization of Six1 varies due to protein size and cell types in different organs. In this study, we focus on the expression and localization of Six1 in male reproductive organ via bioinformatics analysis and immunofluorescent detection. The potential interacted proteins with Six1 were also predicted by protein-protein interactions (PPIs) and Enrichr analysis. Bioinformatic data from The Cancer Genome Atlas and Genotype-Tissue Expression project databases showed that SIX1 was highly expressed in normal human testis, but low expressed in the testicular germ cell tumor sample. Human Protein Atlas examination verified that SIX1 level was higher in normal than that in cancer samples.The sub-localization of SIX1 in different reproductive tissues varies but specifically in the cytoplasm and membrane in testicular cells. In mouse cells, single cell RNA-sequencing data analysis indicated that Six1 expression level was higher in mouse spermatogonial stem cells (mSSCs) and differentiating spermatogonial than in other somatic cells.Immunofluorescence staining showed the cytoplasmic localization of Six1 in mouse testis and mSSCs. Further PPIs and Enrichr examination showed the potential interaction of Six1 with bone morphogenetic protein 4 (Bmp4) and catenin Beta-1 (CtnnB1) and stem cell signal pathways. Cytoplasmic localization of Six1 in male testis and mSSCs was probably associated with stem cell related proteins Bmp4 and CtnnB1 for stem cell development.

ObjectiveTo analyze the reliability and validity of Chinese version of Dysarthria Impact Profile (DIP) in assessment of the psychosocial impact of dysarthria in Parkinson's disease (PD). MethodsFrom May, 2021 to March, 2022, 43 PD patients from Department of Rehabilitation Medicine, the First Affiliated Hospital of Sun Yat-sen University were selected, and 43 age matched healthy controls were enrolled. The process of translation and adaptation was used to develop the Chinese version of DIP, and two groups were evaluated. The internal consistency reliability and intra-rater reliability were analyzed as well as the correlation between each item and its subscale, DIP scores to the Voice Handicap Index (VHI) and 36-item Short Form Health Survey (SF-36). DIP scores of two groups were compared. ResultsThe Cronbach's α was 0.732 to 0.942. The intra-rater correlation coefficient of subsection four was the highest (r = 0.670, P < 0.001). The correlation coefficients were 0.315 to 0.871, which were correlated (P < 0.05), except items 1, 6, 11 of subsection three and item 11 of subsection four. The correlation coefficient between DIP and VHI was -0.821 (P < 0.01), and it was 0.684 (P < 0.01) between DIP and SF-36. DIP scores were significant different between PD patients and the control group (P < 0.01). ConclusionThe Chinese version of DIP shows good reliability and validity, and can be used as a tool to measure the psychosocial impact of dysarthria in PD patients.

Two cases of hypoglossal canal dural arteriovenous fistulas (HCDAVF) were reported. The clinical manifestation, radiological features, treatment and prognosis were reviewed. Both cases presented chemosis and pulsatile tinnitus. 3D-time-of-flight (TOF) magnetic resonance angiography (MRA) demonstrated abnormal high signal in hypoglossal canal. Cerebral digital subtraction angiography (DSA) showed that these HCDAVFs were supplied by multiple intracranial and extracranial arteries, and fistulas were located in hypoglossal canal. Fistulas were blocked by coils and Onyx-18 through transvenous approach, and the angiography after the embolism showed complete occlusion of fistula. No adverse events after treatment and no recurrence during the follow up were observed.
