OBJECTIVETo investigate the mid-term outcome of operation for thoracolumbar tuberculosis. METHODS : Twenty-eight patiens with thoracolumbar tuberculosis underwent one stage anterior debridement,interbody fusion with bone graft and posterior pedicle screw internal fixation treatment from July 2006 to July 2011. There were 17 males and 11 females. Total 17 patients had nerve injuries ,including 6 cases of grade B, 5 cases of grade C, 6 cases of grade D according to Frankel classification. The poisoning symptoms of tuberculosis and recovery of spinal function were observed. The bone fusion and recovery of [umbar function were evaluated.

RESULTSAll the patients were followed up ,and the duration ranged from 39 to 85 months (mean 57 months). The clinical symptoms were controlled gradually, and the thoracolumbar back pain was alleviated after operation. Among the 17 patients with complications of nerve injuries, 3 patients were improved from preoperative grade B to postoperative grade D, 3 patients were improved from preoperative grade B to postopertive E, 5 patients with preoperative grade C and 6 patients with preoperative D were almostly recovered to normal after operation. According to JOA scoring system for curative effect evaluation, the excellent and good rate at the 3rd month, the 1st year, the 3rd year and the 5th year after operation were 67.86% ,82.14% ,85.71% ,89.29% and 91.30% respectively. The results at the 6th month and the 1st year had no statistical differences compared to the results at the 3rd month (P > 0.05); but the results at the 3rd year and the 5th year were better than that at 3 months after operation (P < 0.05); and the results between 3 yesrs and 5 years after operation had no statistical differences (P < O.05). The degeneration of adjacent segments were evaluated according to the California University (Universith of California at Los Angeles , UCLA) score. The degeneration rate was 53.57% (15/28) at the 3rd year after surgery, which was better than that before surgery. Twenty-three patients were followed up for 5 years ,and the degeneration rate was 86.96% (20/23) ,which was better than those of before surgery and 3 years after surgery.

CONCLUSIONThe surgical treatment for thoracolumbar spinal tuberculosis can achieve the thorough debridement, reconstruction of spinal stability, recovery of lumbar function and promote the functional recovery of the spinal cord, which is an effective method of treatment. However, the mid term follow-up showed that more severe degenerative changes were found in the postoperative adjacent segment.

Chinese medicinal authentication is fundamental for the standardization and globalization of Chinese medicine. The discipline of authentication addresses difficult issues that have remained unresolved for thousands of years, and is essential for preserving safety. Chinese medicinal authentication has both scientific and traditional cultural connotations; the use of scientific methods to elucidate traditional experience-based differentiation carries the legacy of Chinese medicine forward, and offers immediate practical significance and long-term scientific value. In this paper, a path of inheritance and innovation is explored through the scientific exposition of Chinese medicinal authentication, featuring a review of specialized publications, the establishment of a Chinese medicine specimen center and Chinese medicinal image databases, the expansion of authentication technologies, and the formation of a cultural project dedicated to the Compedium of Materia Medica.

OBJECTIVETo summarize the clinical application results of the repair soft tissue defect in contralateral leg with a cross-leg soleus muscle flap pedicle transplantation.

METHODSFrom January 2008 to January 2013, 8 patients with soft-tissue defect in lower leg underwent reconstruction with a cross-leg soleus muscle flap pedicle transplantation (without microvascular anastomoses). There were 7 males and 1 female, aged from 20 to 49 years old with an average of 31.8 years. The operative time after injury was from 2 to 8 weeks with the mean of 46 days. The soleus muscle flap was transposed across to the contralateral leg defect area, then immediate to perform the coverage of the muscle flaps by a meshed split-thickness skin graft. The donor site was closed directly.

RESULTSAll the muscle flaps had survived completely. In one case, recipient area edge had a less exudate from drainage hole everyday, the incision spontaneously was healed after 2 week's changing dressing. Follow-up period ranged form 1.5 to 4 years with an average of 2.5 years postoperatively. The tibia and fibula fractures were healed well. A good contour was achieved at the recipient area. According to LEM standard, 2 cases got excellent results, 5 good and 1 fair.

CONCLUSIONSoleus flap pedicle transplantation is very suitable to repair the soft tissue defect of the injuried leg only one main blood vessel, and can reduce the damage of donor area.

OBJECTIVETo summarize the clinical application result of the selective nerve root blocks in limited operation of the lumbar spine.

METHODSFrom January 2008 to October 2012,68 patients with lumbar spinal canal stenosis with multiple levels were underwent the selective nerve root blocks in limited operation of the lumbar spine,including 47 males and 21 females with an average age of 56 years old ranging from 45 to 80. After never roots blocks,64 cases were positive for limited operation of the lumbar spine; the other 4 cases were negative and abort the operation.

RESULTSThe nerve roots block operation smoothly and no complications related to the nerve roots block occurred. There was no neurologic injury complication in this study. Follow-up period ranged from 16 to 45 months postoperatively (means, 32 months). The recovery effect was calculated with Macnab scores, the result was excellent in 44 cases, good in 18 cases, poor in 1.

CONCLUSIONOperative treatment for lumbar spinal canal stenosis with multiple levels is focused on the areas causing symptomate neural compression rather than prophylactic decompression at areas of nonsymptomatic disease. Application of selective nerve root blocks can accurately judge the responsible vertebral body and pain source and improve the curative effect of limited operation of the lumbar spine

OBJECTIVETo study the antioxidation activity and protective effect of ginger oil on DNA damage.

METHODChemical light assay was used to detect the oxygen radicals scavenging capacity of ginger oil. The erythrocyte oxidation damage was induced by H2O2. The effect of ginger oil on oxidative erythrocyte was observed by the colorimetric analysis assay, and the content of malondialdehyde (MDA) in rabit hepatocyte was measured. The anaylsis of DNA damage was made with single cell gel electrophoresis(SCGE) technique.

RESULTGinger oil might decrease light value compared with control group and inhibited erythrocyte oxidation damage. Compared with that in control group, the degress of DNA damage reduced significantly in the protected groups. Ginger oil might decrease the content of MDA remarkably and inhitibition rate was 48.16%.

CONCLUSIONGinger oil has dominantive protective effect on DNA damage induced by H2O2. Ginger oil might act as a scavenger of oxygen radical and might be used as an antioxidant.

OBJECTIVETo study the effects of strontium ranelate on osteoporosis induced by simulated weightlessness in male rats.

METHODSTwenty-seven male SD rats were randomly divided into 3 groups, namely the normal control group (group A) and two groups of weightlessness simulated by tail suspension (groups B and C). The rats in group C were treated with strontium ranelate, and those in the other two groups were given the same dose of normal saline for 28 consecutive days.

RESULTSThe rats in group B showed significantly lower levels of alkaline phosphatase (ALP), bone mineral density (BMD) and bone mineral content (BMC) than those in group A (P<0.05), but serum calcium and phosphonium concentrations underwent no significant changes in the 3 groups (P>0.05). In the rats of group B, the trabeculae of the femur became thinner, fragile, and discontinuous with reduced quantity as compared with those in group A. The rats in group C had greater number of the trabeculae than those in group B with decreased resorption surface and more regular arrangement of the collagen fibers.

CONCLUSIONStrontium ranelate may produce beneficial effect on the bone microstructure, reduce bone loss and stimulate bone formation in male rats subjected to simulated weightlessness.
