Objective To study the effects of one finger massage on sciatic nerve injury rats. Methods The sciatic nerves were exposed, and the sciatic nerve was held by micro needles to make the sciatic nerve injury model. SD rats were randomly divided into sham-operation group, model group and massage group. In the sham-operation group, the sciatic nerves were exposed but not held. 7 d after the establishment of modeling, rats in massage group received one finger massage for 30 d. After 30 d, SFI and BBB of sciatic nerves were detected. HE staining, transmission electron microscope and immunochemistry assay were used to measure the changes of sciatic nerves. Results Compared with model group, massage group could speed up the recovery of SFI and increase BBB, promote the recovery of sciatic nerve morphology, increased protein level of S-100β, and enhance ultrastructure of newborn nerve growth and recovery. Conclusion One finger massage can effectively promote neurological and functional recovery after sciatic nerve injury in rats.

On March 18, 2016, one 53 years old man with burns on perineal region and complicated by secondary multiple organ injuries by exposing to paraquat fluid was admitted to our department. Comprehensive treatment measures including protective mechanical ventilation, intensive care, vacuum sealing drainage, anti-infection, and organ protection were conducted sequentially. Through 33 days of comprehensive treatment and nursing, the patient′s condition substantially improved and he left hospital. This case presents that paraquat fluid absorption through skin and mucosa can also lead to severe systemic poisoning, and multiple organ protection is the key to improve the prognosis of this patient.
