ABSTRACT
Objective To investigate the effects of 654-2 acupoint injection at Zusanli combined with shiatsu at Neiguan acupoint for colonoscopy analgesia. Methods Totally 140 patients underwent colonoscopy were divided into observation group and control group according to the random number table method, with 70 cases in each group. The observation group were given 654-2 acupoint injection at Zusanli (5 mg each side) combined with shiatsu at Neiguan acupoint (the patient to feel the acid, swelling, hemp began to check, until colonoscopy to return to the ileocecum, stop pressing), and the control group were given 654-2 muscle injection (10 mg) 10 min before colonoscopy. The pain scores, checking time and patients'' satisfaction degree of the two groups were compared, and serum beta-endorphin (β-EP) and substance P (SP) level of the two groups before and after examination were compared. Results The pain degrees during colonlscope inserting and passing the sigmoid, splenic flexure of colon of the observation group were significantly lower than those of the control group (P<0.001); testing time was less than that of the control group (P<0.001); patient satisfaction scores were higher than those of the control group (P<0.001); serum β-EP level after examination was higher than that of the control group (P<0.001); SP level was lower than that of the control group (P<0.001). Conclusion 654-2 acupoint injection at Zusanli combined with shiatsu at Neiguan acupoint for colonoscopy analgesia can adjust the serum levels of β-EP and SP, with obvious analgesic effect, which can shorten the testing time.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the feasibility and clinical effects of titanium elastic nail (TEN) for treatment of proximal radius epiphyseal injuries of O'Brien type III.</p><p><b>METHODS</b>From October 2008 to November 2009,19 patients with proximal radius epiphyseal injuries of O'Brien type III were treated with internal fixation, including 13 males and 5 females with an average age of 8.3 years old ranging from 6 to 12 years. The average time from injury to surgery was 3.5 days (2 to 7 days). The reduction situation after operation was assessed by Métaizeau criteria, and the elbow function after operation were evaluated by Broberg-Morrey elbow score.</p><p><b>RESULTS</b>All patients were followed-up for 8.7 months in average (ranged 6 to 12 months). No infection, TEN brokage, skin bursting and other complications occurrenced. According to Métaizeau criteria, the results were excellent in 7 cases, good in 10 cases and fair in 2 cases. The Broberg-Morrey score rose from preoperative (47.3 +/- 5.1) to (86.6 +/- 6.3) at 3 months followed-up (t=139.17, P=0.0002); the outcome was excellent in 7 cases, good in 9 cases, and fair in 3 cases.</p><p><b>CONCLUSION</b>Internal fixation with TEN in treatment of proximal radius epiphyseal injuries of O'Brien type III has a limited invasion, cosmetic beauty, safety and reliability advantages. This technique provides a reliable alternative in proximal radius epiphyseal injuries of O'Brien type III.</p>

Objective The goal of this study was to investigate the biomechanical compatibility effects of cancellous bone granule(CBG) augmentation of Optimesh and polymethylmethacrylate (PMMA) augmentation of Kyphoplasty on treated andadjacent non-treated vertebral bodies. Methods Three-dimensional, anatomically detailed finite element (FE) models of the L1–L2functional spinal unit (FSU) were developed on the basis of cadaver computed tomography (CT) scans. The material properties and plug forms of the L2 centrum were adapted to simulate osteoporosis, CBG and PMMA augmentation. The models assumed a three-column loading configuration as the following types: compression, flexion and extension. Results Compared with the osteoporotic model, changes in stress and strain at adjacent levels both of CBG and PMMA augmentation models were minimal, but stresses/strains within the two reinforcement material plugs were modified distinctly and differently. In addition, osteoporosis, CBG and PMMA augmentation had little effect on either the axial compressive displacement of the three columns or the average disc internal pressure in all models. Conclusion Both morcelized cancellous bone and PMMA augmentation restore the total strength and stiffness level of treated vertebral bodies and benefit the reconstruction of vertebral function. Regarding the biomechanical compatibility and the biocompatibility of the treated vertebral body and reinforcement material, however, the morcelized cancellous bone is better than PMMA augmentation.
