Precise Resection of Macrodactyly Under Assistance of Three-Dimensional Reconstruction Technology: A Case Report.

Macrodactyly of the foot is an extremely rare congenital malformation characterized by an increase in the size of all the elements or structures of a digit or digits. Most sources indicate that macrodactyly affects the hand more often than the foot. This rare medical condition usually requires surgical intervention with a precise preoperative plan and postoperative rehabilitation.

Application of custom anatomy-based nerve conduits on rabbit sciatic nerve defects: and evaluations.

The intermingling of regenerated nerve fibers inside nerve grafts is the main reason for mismatched nerve fibers. This is one of the key factors affecting limb function recovery after nerve injury. Previous research has shown that the accuracy of axon regeneration can be improved by a bionic structural implant.

A special case of Wellens' syndrome.

Wellens' syndrome is a pattern of electrocardiographic T-wave changes associated with critical stenosis of proximal left anterior descending artery (LAD). T-waves abnormalities were found in precordial leads, especially in V2-V3 during pain-free periods, and ECG obtained during episodes of pain demonstrates upright T-waves with possible elevated or isoelectric ST segments. Early recognition and appropriate intervention carries significant diagnostic and prognostic value.

Influence of fastigial nucleus stimulation on heart rate variability of surgically induced myocardial infarction rats: fastigial nucleus stimulation and autonomous nerve activity.

Electrical stimulation of the rostal cerebellar fastigial nucleus (FNS) has been proved to have neuroprotective effects, but it is not known whether FNS also has a cardioprotective effect. One hundred Sprague-Dawley rats were randomly allocated into four groups, including a sham-operation group (Sham group), rats whose coronary arteries were ligated but the FNs were sham stimulated (AMI group), rats in which both coronary arteries were ligated and FNs were stimulated (FNS group), and rats whose fastigial nuclei were lesioned 5 days before ligation, then their coronary arteries were ligated and FNs were stimulated (FNL group). Heart rate variability parameters were monitored 6 h, 24 h, 7 days and 21 days after ligation, and mortality rates, hemodynamic parameters and infarction sizes were compared after 21 days.
