We sought to compare the early radial injury after TRI between first-TRI and repeat-TRI by ultrasound biomicroscopy （UBM）. Methods A total of 1116 patients who underwent the transradial coronary procedures were enrolled. The patients depending on whether for the first time to accept transradial coronary procedure were divided into first-TRI group and repeat-TRI group. The RA was examined by UBM before and one day after the procedure. Results Compared with first-TRI group, the mean RA diameter of repeat-TRI one day after the procedure decreased significantly （P 〈0.05）. In first-TRI group, the mean RA diameter was （2.32±0.53） and （1.93±0.57） mm before procedure and one day after the procedure respectively （P 〈0.05）. In repeat-TRI group, the mean RA diameter was （2.37±0.51） and （1.79±0.54） mm before procedure and one day after the procedure, respectively （P 〈0.01）. Compared with first-TRI group, the mean RA diameter was reduced significantly in repeat-TRI group one day after the procedure （P〈0.05）. The early radial injuries and intimal thickening were compared between first-TRI and repeat-TRl. The mean intima-media thickness of RA was （,0.24±0.13） mm and （0.59±0.28） mm before procedure and one day after the procedure in first-TRI group. The mean intima-media thickness of RA was （0.29±0.16） mm and （0.68±0.32） mm before procedure and one day after the procedure in repeat-TRI group. Compared with first-TRI group, the mean intimal thickening was increased significantly in repeat-TRI group one day after the procedure （P〈0.05）. Intimal dissection, stenosis and occlusion were all significantly greater in repeat-TRI RAs （P 〈0.05）. Linear regression analysis revealed that diameter, repeated TRI procedure and PCI procedure were the independent predictors of intimal thickening. Conclusions RA early injuries were greater in repeat-TRI patients than in first-TRI patients. We first use high-resolution UBM imaging to demonstrate the rate of radial injury and revealed that diameter, repeated TRI procedure and PCI procedure were the independent predictors of intimal thickening.展开更多

Methods： Acupuncture at the unilateral points of Hegu （LI4）, Waiguan （TB5）, Shousanli （LI10）, Quchi （LI11） and the bilateral points of Zusanli （ST36）, accompanied by method of electro-acupuncture. Results： After three courses of acupuncture treatment （30 minutes each time, 6 times each course）, the patient presented the symptoms of making a fist strongly, disappearance of wrist drop, and positive sign of lifting wrist assay in turn. Simutaneously, the grip strength of hand increased and the strength of muscle reach over level 4. Conclusion： With the help of electro-acupuncture, acupuncture therapy can relieve pain, improve the local blood supply of nerve injury and then repair the damage of the nerve.展开更多

There were 9 spiral fractures (type A1), 1 oblique fracture (type A2), 3 transverses fractures (type A3) and 20 comminuted fractures (11 type B1, 9 type B2) according to AO classification. Fifteen cases were treated with open reduction and limited internal fixation and fixation with external fixators, 10 cases treated with open reduction and fixation with external fixators, and 8 cases treated with closed reduction and fixation with external fixators. Nerve exploration was undertaken in 9 cases with preoperative radial nerve injury. External fixators were removed after bone healing. The average follow-up was 18 months with a range from 8 to 24 months. Results: The time of bone healing ranged 11-22 weeks (average 14 weeks). The latest follow-up showed the functions of 9 cases of preoperative radial nerve injury and of 2 cases postoperative radial nerve injury and the function of elbow were recovered to normal. There were only 7 cases of superficial infection at pin hole, which was subsided by using oral antibiotics and pin-hole care with mild disinfectants.Conclusions: Fixation with unilateral external fixators combined with open reduction and limited internal fixation has a good effect in the treatment of lower third humeral shaft fractures.展开更多
