OBJECTIVETo introduce an operation for fingertip reconstruction.

METHODSThe vascularity of the reverse dorsal island flap is augmented by performing an arteriovenous anastomosis between the dorsal vein in the flap and a digital artery at the fingertip. The flap was used in ten patients for reconstruction of their fingertip defects.

RESULTSAll the ten flaps survived and the appearance was good.

CONCLUSIONThe method is easy except for the necessity of performing standard microvascular surgery. The flap is a good option for repairing fingertip defects.

Objective To investigate the correlation and predictive effect of serum CD4+/CD8+T lympho-cyte ratio combined with magnetic resonance angiography(MRA)on recurrence of cerebral infarction.Meth-ods A total of 153 patients with acute cerebral infarction admitted to the Zhenjiang First People's Hospital from January 2021 to February 2022 were selected.CD4+/CD8+T lymphocyte ratio of patients was deter-mined,vascular stenosis score and collateral circulation filling score were evaluated by MRA.The patients were followed up for 1 year,including 34 patients with recurrent cerebral infarction as recurrent cerebral in-farction group,107 patients without recurrent cerebral infarction as the non-recurrent cerebral infarction group,12 patients were excluded due to other causes of loss of follow-up,and the receiver operating character-istic(ROC)curve for using the indicators to predict the recurrent cerebral infarction was drawn.Results The CD4+/CD8+T lymphocyte ratio in recurrent cerebral infarction group was significantly higher than that in non-recurrent cerebral infarction group(P<0.05).Vascular stenosis score and collateral circulation filling score in recurrent cerebral infarction group were lower than those in non-recurrent cerebral infarction group(P<0.05).The recurrence of cerebral infarction was correlated with CD4+/CD8+T lymphocyte ratio,vascu-lar stenosis score and collateral circulation filling score(P<0.05).ROC curve analysis showed that the area under the curve(AUC)of CD4+/CD8+T lymphocyte ratio,vascular stenosis score,and collateral circulation filling score to predict recurrent cerebral infarction was 0.975,0.889,and 0.935,respectively,and the AUC of recurrent cerebral infarction was 0.994 when combined with the three factors.The AUC of cerebral infarction recurrence was significantly higher than that of each index alone.Conclusion Serum CD4+/CD8+T lympho-cyte ratio combined with MRA vascular stenosis score and collateral circulation filling score have high efficacy in the diagnosis of recurrent cerebral infarction,which have predictive value for recurrent cerebral infarction.
