Aim To investigate the anti-inflammatory molecular mechanism of chlorogenic acid extracted from Lonicera confusa DC in vitro.Methods PM? of a rat was segregated.MTT assay was used to detect the effects of the chlorogenic acid on PM? cells growth activities. PM? was stimulated with LPS for a prolonged period,ELISA was used to detect the level of TNF-?,IL-6 and PGE2 in the supernatant;COX-2 activity was determined by the level of PGE2 in the supernatant.After stimulating PM? with A23187 for a short time,the 6-keto-PGF1? level in the supernatant was measured by radioimmunoassay to express COX-1 activity.Results Chlorogenic acid had no inhibitive effects between 31.25 mg?L-1 and 1000 mg?L-1.The level of TNF-?,IL-6 and PGE2 in drug groups was lower than that of LPS-induced group,and the difference was significant,in a dose-dependent manner.The concentration of 50 mg?L-1 group was ineffective in the expression of TNF-?.Low concentration chlorogenic acid inhibited the expression of 6-keto-PGF1?,while high-concentration induced it.Conclusions The anti-inflammatory effect of chlorogenic acid may be related to inhibiting TNF-?,IL-6 activity and affecting exogenous AA metabolism.

Cytometric bead array (CBA) is a new analytical technique, which can achieve real-time and rapid detection of targeted components in a small amount of sample. With many advantages of high throughput screening, high specificity and sensitivity, low cost, easy operation and good repeatability, this CBA technique has been widely used for the detection of various components in foods, agricultural products and environmental samples. Recently, it has got significant development in rapid detection of small molecules. This review briefly introduced the theory of CBA technique, summarized the application in the analysis of small molecules, such as mycotoxins, pesticide residues, shellfish toxins, and then prospected the application of trace small molecules detection in the complex matrices of traditional Chinese medicine and the development trend of it.

Objective To prospectively explore the techniques and correction results of the method of vertebral coplanar alignment (VCA) in posterior correction for thoracic scoliosis. Methods Between June 2008 to March 2009, 27 patients with idiopathic thoracic scoliosis were selected to undergo posterior pedicle screw fixation with assistance of Coplanar system. There were 26 females and 1 male with the average age of 15.9 years(ranged 11-23 years). There were type 1 in 25 cases and type 2 in two cases. The levels of fusion were established according to the Lenke criteria. The average preoperative coronal Cobb angle was 49°(ranged 40°-70° ). During the procedure, the pedicle screws were inserted in each involved levels on the convex side, an extended Coplanar tube was screwed in line with screw axis to each screws. Then two rigid bars were inserted through the uppermost part of the slotted tube sequentially. As the bar was gently driven down toward the bottom end, the pedicle screws axis started to converge in the straight line, correcting translation and rotation. Spacers were inserted into the slots of the tubes to achieve the ideal physiologic thoracic kyphosis. Once the rod was fixated in the concave side of the main curve, the Coplanar system could be removed. Results The mean postoperative Cobb angle was 14° (ranged 6°-25°), representing the correction rate of 70.7%. The average duration of surgery was 245 min (ranged 210-300 min) and a mean estimated blood loss was 1500 ml (ranged 600-2100 ml). The duration of follow-up averaged 15 (12-18) months. The loss of correction at last follow-up was 3° with the loss of correction rate of 6.1%. In the sagittal plane, the thoracic kyphosis was restored from 18° to 25°. No coronal or sagittal plane decompensation occurred. No thoraeoplasties were necessary to correct the residual rib hump. There was no death, infection and neurological complications. Conclusion The Coplanar is a new technique for the correction of scoliosis, its advantage lies in excellent and modulatable three-dimensional correction with a single and standardized maneuver.

Objective To analyze the influence of the Risser sign on the sagittal compensatory mode of the spine in idiopathic thoracic scoliosis after anterior spinal fusion.Methods Between June 2002 and November 2006,43 adolescent idiopathic scoliosis(AIS)patients(Lenke 1)undergone anterior correction with a minimum 2 years follow-up were included in this study.The patients were divided into three groups according to the Risser sign:group A(Risser 0),group B(Risser 1-3),and group C(Risser 4-5).The preoperative,postoperative and follow-up sagittal profile were evaluated by the following radiological parameters measured on the lateral radiograph,including the thoracic kyphosis,the lumbar lordosis,the thoracolumbar junction kyphosis,the distal junctional kyphosis,and the sagittal vertical axis.Results In group A,the thoracolumbar junction kyphosis significantly changed from-1.7° preoperative to 6.6° at the final follow-up,with an average increase of 8.3°.Similarly,in group B,the thoracolumbar junction kyphosis changed from -7.3° before surgery to 0.6° at the final follow-up,with an average variation of 7.9°.No obvious change of the thoracolumbar junction kyphosis was observed in group C.At the final follow-up,the average thoracic kyphosis in three groups was 21.2°,18.4° and 14.7°,respectively.No significance of the variation of the thoracic kyphosis was observed in the three groups,however,in group A and B,the thoracic kyphosis showed an ascending trend during the follow-up without significant statistical difference,in addition; the ratio of the thoracic kyphosis increased in group A was higher compared with group B and C.Conclusion For AIS patients with low Risser sign,the increased thoracic kyphosis,and the thoracolumbar junction kyphosis may be ascribed to the decompensation of thoracolumbar region caused by the reconstruction of sagittal alignment due to the continued growth of posterior elements of the thoracic spine.
