Early-middle stage effect of percutaneous spinal endoscopic BEIS technique for lumbar spinal stenosis / 中国骨伤

OBJECTIVE@#To explore the clinical early-middle stage clinical effect of percutaneous spinal endoscopic with the technique of Broad Easy Immediate Surgery(BEIS) for lumbar spinal stenosis.@*METHODS@#The clinical data of 57 patients with lumbar spinal stenosis treated by surgery from June 2015 to June 2016 were retrospectively analyzed, including 32 cases treated by percutaneous spinal endoscopic with the technique of BEIS (minimally invasive group) and 25 cases by posterior approach of lumbar pedicle screws internal fixation and intervertebral disc excision with bone graft fusion surgery (open surgery group). The pre-operative general data such as age, Body Mass Index (BMI) and etc. were analysed and compared. The operation time, intraoperative blood loss, hospitalization time of the two groups were analyzed. Visual analogue score(VAS), Oswestry Disability Index(ODI), Japanese Orthopedic Association Score(JOA) of preoperative and at 1 week, 1 month, 3 months, 6 months after surgery were used to evaluate the clinical outcome of the two group.@*RESULTS@#All the operations were successful and all the patients recovered smoothly without severe complications, all the wounds got good healing. The pain of the lumbar and lower limb had been improved after surgery. All the patients were followed up more than 6 months with an average of(10.65±3.38) months. There was no significant difference in general data such as age, BMI, and etc. between two groups(>0.05). There were significant differences in VAS, ODI between two groups at 1 week, 1, 3, 6 months after surgery(0.05). Intraoperative blood loss and hospitalization time of minimally invasive group was less than that of open surgery group.@*CONCLUSIONS@#BEIS technique has the advantage of less trauma, less bleeding for lumbar stenosis when compared to open surgery. It can better alleviate the postoperative local lumbar pain, and early-middle clinical effect is equivalent to open surgery, so it can be used as a safe and effective surgical treatment for lumbar spinal stenosis.

Comparative analysis on seedling growth dynamics and physiological indices of Bupleurum smithii var. parvifolium and B. scorzonerifolium / 中国中药杂志

With Bupleurum smithii var. parvifolium and B. scorzonerifolium as test objects, in order to provide a theoretical basis for the introduction and domestication of B. smithii var. parvifolium, the growth and development dynamics of seedlings, biomass accumulation, the content of malonaldehyde(MDA), the activity of antioxidase such as SOD, POD, CAT and APX between them were comparatively analyzed by direct sowing culture in the open field. The results indicated that the morphological index and the biomass accumulation of B. smithii var. parvifolium such as root diameter, root length, plant height and leaf number were inferior to B. scorzonerifolium, the antioxidase SOD and POD activity of B. smithii var. parvifolium was significantly inferior to B. scorzonerifolium (<0.05), the antioxidase CAT and APX activity of B. smithii var. parvifolium was inferior to B. scorzonerifolium but the difference wasn't significant, while MDA content was superior to B. scorzonerifolium(<0.05). Thus, compared with cultivated B. scorzoneri folium, the plant growth velocity of wild B. smithii var. parvifolium was relatively slower and its resistance was relatively weaker after introduction and domestication.

Radial artery recurrent branch of styloid process bone flap transfer for treatment of scaphoid nonunion / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the clinical efficacy of radial artery recurrent branch of the styloid process bone flap transfer for treatment of scaphoid nonunion.</p><p><b>METHODS</b>From 2002 to 2007, 18 patients with scaphoid nonunion included 12 males and 16 females with an average age of 31.2 years old ranging from l8 to 51 years. Time from injury to operation was 8 to 26 months (averaged 12.5 months). Radial bone flap blood supply by radial artery recurrent branch of styloid process was embedded in retrograde scaphoid shift distance at both ends, Kirschner wire fixed on the bone flap and bone fractures, and the radial styloid process was resected. Cast gypsum immobilization in a neutral place of wrist were performed for 6 to 8 weeks, the rehabilitation of physical therapy and functional exercise were performed after removal. Kirschner wire were removed after X-ray showed fracture healing.</p><p><b>RESULTS</b>Among them, 15 cases were followed-up for from 8 to 25 months (means 13 months). All fractures healed. The healing time was 8 to 12 weeks. According to adult forearm fracture evaluation of Anderson the results were excellent in 14 cases, good in 1.</p><p><b>CONCLUSION</b>The radial artery recurrent branch of styloid process bone flap has a wealth of blood circulation, can make free grafting of the creeping substitution process directly into the healing process.</p>
