The aim of this study focused consequently on the GC fingerprint of its volatile oil. Method: Gas chromatographic experiment was carried out, and the GC fingerprint was generated. Results: The GC fingerprints of the authentic samples and the commercial samples collected from various sources expressed very close similarity and its congeners can be easily distinguished each other.

[Objective]To discuss the diagnosis and surgical treatment of spinal myeloma.[Method]To make a retrospective analysis of cliniacal history and operation results of 13 patients with spinal myeloma from 1999 to 2004.There were 5 males and 8 females with average age of 47.67 years.They were diagnosed by X-ray,CT,MRI,ECT and biopsy.Resection of tumor was performed in all cases,of which 7 cases was through anterior approach,4 cases through posterior approach,2 cases through combined approach.[Result]The pain was decreased and neurological function was improved in all cases after the surgery.Three death and one recurrence was found during the follow-up time.[Conclusion]X-ray,CT and MRI are essential for diagnosis,ECT may help found multiple lesions,biopsy is reliable diagnosable method.Surgery can relived the symptoms obviously,but should be associated with adjuvant treatments.

[Objective]To approach the clinical characteristic,diagnosis and method of treatment of malignant fibrous histiocytoma of bone.[Method]The clinical data of 52 patients of malignant fibrous histiocytoma of bone were analyzed retrospectively,including sites of tumor,preoperative imageology,puncturing biopsy,surgical staging of tumor,methods of treatment,results of follow-up,and so on.[Result]In all 52 cases of malignant fibrous bistiocytoma of bone,32 cases were in periphery of knee joint,14 cases in periphery of shoulder joint,3 cases in the proximal femur,1 case in calcaneus,1 case in lumbar and 1 case in ilium.The preoperative imageelogy and puncturing biopsy were made as usual.There were 20 cases in staging of ⅡA and 32 cases in in staging of ⅡB according to Ennekings surgical staging of tumor.All cases were performed operation except of 1 case.The operation were made salvage limb mosfly and the ratio of limb salvage was 74.5 %(38/51).The preoperative and postoperative chemotherapy and radiotherapy were performed at the same time.Thirty-six of all cases were in long-time follow-up and the ratio of follow-up was 69.2%(36/52).Nine cases were recurred in the region,6 cases had distant metastasis and survival rate of 5 years was 61.1%(22/36).[Conclusion]Preoperative puncturing biopsy and imageology can help the diagnosis of malignant fibrous histiocytoma of bone.Surgery is the primary method and radiotherapy and chemotherapy can prevent the recurrence of the tumor.The resection of the tumor thorough is the key point of healing of malignant fibrous histiocytoma of bone.

Accurate placement of pedicle screws is a key factor of spinal surgery. Investigation of a new real-time intra-operative monitoring method is an important area of clinical application research which makes a contribution to planting pedicle screw accurately. Porcine spines were chosen as experimental objects. The changes of reduced scattering coefficient (μ'(s)) along normal puncture path, medial perforation path and lateral perforation path were measured and studied. A conclusion is drawn that there are two distinct peaks throughout the puncture process, appearing at the junction of cancellous bone and cortical bone, at the beginning and at the end, respectively. The reduced scattering coefficient is proved to be a good monitoring factor which can identify whether the screw is about to reach the critical position of the spine puncture. Moreover, the variation provides an important reference for spinal surgical navigation process.

We used near-infrared spectroscopy technology to monitor and assess the treatment effect of dehydrating agent in injured rat brain in real time style. We employed the brain edema model in rats resulting from Feeney' s freefall damage, then treated with different doses of mannitol, and collected reduced scattering coefficient (p',) and intracranial pressure (ICP) values after the injury and during the treatment. The results showed that brain edema happened 1 h after the injury in rats' brain tissue, peaked around 72 h after injury, and then began to decrease gradually. The reduced scattering coefficient and ICP values of the treatment group injected with mannitol all decreased after administration. Compared with the effect of low-dose mannitol treatment, that of high-dose mannitol treatment was much better. The duration of the plateau was longer and most experiments results declined significantly. From this we conclude that the reduced scattering coefficient and ICP are consistent with the trend changes, and the reduced scattering coefficient could be used as an indicator for monitoring cerebral edema.

Objective To detect the change of CD47 on T-lymphocyte subsets marked by CD3 + CD4+ and CD3+ CD8+ in the acute graft versus host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to explore its clinical significance.Methods The peripheral blood of 30 patients was collected before and every two weeks from hematopoietic reconstitution after allo-HSCT.The expression of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ was detected by flow cytometry,and the relationship between their expression and the occurrence of aGVHD was analyzed.Results The percentage of CD3+ CD4+-and CD3+ CD8+-marked T-lymphocyte subsets showed no statistically significant difference between aGVHD group and non-aGVHDgroup [(38.95 ± 6.18)％ vs.(37.38 ± 4.6)％,and (22.35 ± 3.32)％ vs.(20.34 ±4.56) ％,respectively] (P＞0.05).The expression levels of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ was obviously increased in aGVHD group when compared to before transplantation and non-aGVHD group after transplantation,and that had no changes in non-aGVHD group when compared to before conditioning regimen after transplantation.Mean fluorescence intensity of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ [(93.70 ± 14.88) and (70.09 ± 12.51)] in aGVHD group significantly increased as compared with non-aGVHD group [(71.27-± 11.32) and (53.93 ± 8.35)] (P＜0.05).There was no significant difference in the expression of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ and CD3+ CD8+ before and after transplantation in non-aGVHD group (P＞0.05).Moreover the expression of CD47 on T-lymphocyte subsets marked by CD3 + CD4 + and CD3 + CD8 + changed correspondingly with the outcome of aGVHD in aGVHD group.Conclusion The change of CD47 on T-lymphocyte subsets marked by CD3+ CD4+ andCD3+ CD8+ is valuable to monitor the aGVHD after allo-HSCT,which may provide a new means for the early detection of aGVHD.
