Interleukin 33 (IL 33),one member of the IL-1 family,is expressed in many types' tissue and regulation of multiple target cells via its suppression of tumorigenicity 2 (ST2) receptor.Therefore,the crucial roles of the novel cytokine IL-33 in allergic,endocrine diseases,infectious diseases and cancer are becoming characterized.The function of IL-33 in different parasite infection is distinctive in parasitic infections,due to the difference in pathogenic mechanism and in the time course of IL-33 expression.

AIM To study the dynamic changes of color and five constituents during processing of Gardeniae Fructus.METHODS Camera and Adobe Photoshop software were applied to collecting images and obtaining chromatic values (L,a,b) of processed products,respectively.HPLC was adopted in the content determination of genipin-1-β-D-gentiobioside,geniposide,crocin-Ⅰ,crocin-Ⅱ,crocin-Ⅲ.Then the correlation between color and constituent contents was investigated by linear regression and partial least squares method.RESULTS With the process of processing,the chromatic values of epicarp and seed pellets expelled showed decreasing trends,especially for that of the former.On the whole,the contents of geniposide,crocin-Ⅰ and crocin-Ⅱ were decreased,while those of genipin-1-β-D-gentiobioside and crocin-Ⅲ were first increased and then decreased.The chromatic values of epicarp and seed pellets expelled showed significant correlations with crocin-Ⅰ content.CONCLUSION Color and crocin-Ⅰ can be considered as control index and monitoring index during processing of Gardeniae Fructus,respectively.

ObjectiveTo Compare the clinical results between microscope and loupes which used in microsurgical discectomy.MethodsA prospective randomized controlled trial of 93 patients who had undergone microsurgical discectomy from January 2007 to December 2010 was performed.Clinical results were assessed by comparing the following parameters between patients who had undergone the surgery by microscope and loupes:length of stay,hospitalization cost,operative time,estimated blood loss,Japanese Orthopaedic Association (JOA) score and JOA recovery rate,Odom's standard.ResultsForty-nine patients underwent surgery by microscope,and forty-four patients underwent surgery by loupes.Eighty patients received outpatient or telephone follow-up.The follow-up period was 6.17 to 52.90 months with an average of (29.64±13.05) months,and the follow-up rate was 86.02%.According preoperative data,the two groups didn't differ with respect to age,gender,level of radiculopathy,or preoperative JOA score and JOA recovery rate.No statistically significant differences were identified in postoperative JOA score and JOA recovery rate,length of stay,hospitalization cost,length of follow-up,or relapse rate.Statistically significant differences were identified in operative time,estimated blood loss,and follow-up JOA score and JOA recovery rate.Conclusion Microscope can provide relatively more clear and comfortable vision for the surgery.It can short the operative time,decrease blood loss,reduce the potential risk of nerve injury,and retain more normal tissue,which can ensure better clinical results.

Objective: To study the effects of glycosaminoglycan from scallop skirt (SS-GAG) on the expression of vascular endothelial growth factor (VEGF) and the mechanism of anti-atherosclerosis action of SS-GAG. Methods: U937 cells were incubated with 80mg/L oxidized low density lipoprotein (ox-LDL) for 48h to establish a macrophage-derived foam cell model. In addition, U937 cells were divided into 6 groups: ①control group; ②ox-LDL group; ③ox-LDL+200mg/L SS-GAG group; ④ox-LDL+400 mg/L SS-GAG group; ⑤ox-LDL+800 mg/L SS-GAG group; ⑥ox-LDL +Heparin 100 mg/L group.After 48h's incubation, the concentration of VEGF in the medium was determined by ELISA. Results: The expression of VEGF in U937 foam cells was obviously higher than that of the control group. After treatment with heparin (100 mg/L) and SS-GAG of different concentrations (200mg/L, 400 mg/L, 800 mg/L), the expression of VEGF decreased obviously, especially in the ox-LDL+800 mg/L SS-GAG group (P<0.01). Conclusion: The antiatherogenic effect of SS-GAG is probably due to its ability to inhibit VEGF expression.

OBJECTIVETo investigate the protective effect of neferine against damages of endothelial cells induced by lysophos-phatidylcholine (LPC) and the relationship with asymmetric dimethylarginine (ADMA).
METHODThe human umbilical vein endothelial cells (HUVEC-12) were treated with LPC (10 mg x L(-1)) for 24 h to establish the model of endothelial cells damages; HUVECs were prior exposed to neferine (0.1, 1.0 or 10.0 micromol x L(-1) ) for 1 h, and then exposed to LPC in the presence of the neferine for 24 h. At the end of the experiment, the cultured medium was collected for measuring the concentration of nitric oxide (NO), aleic dialdehyde (MDA) as well as ADMA and the cells were collected for measuring the level of intracellular reactive oxygen species (ROS).
RESULTCompared with control group, exposure of endothelial cells to LPC (10 mg x L(-1)) for 24 h significantly increased the concentration of MDA and ADMA in the medium and the level of intracellular ROS and coinstantaneously significantly decreased the concentration of NO in the medium. Neferine (0.1, 1.0 or 10.0 micromol x L(-1)) significantly inhibited the elevated concentration of MDA, ADMA as well as the level of intracellular ROS and coinstantaneously significantly attenuated the decreased level of NO induced by LPC.
CONCLUSIONNeferine can protect the endothelial cells against damages induced by LPC and the protective effect is related to the decrease of the concentration of ADMA.

OBJECTIVE:
To determine the diagnostic value of the integrated backscatter (IBS) technique for carotid artery atherosclerosis (AS), to investigate the correlation between IBS of carotid artery and the serum level of matrix metalloprotease-9(MMP-9), and to explore the effect of simvastatin on the IBS value of the carotid artery and serum MMP-9 level in hyperlipemia patients.
METHODS:
Fifty-eight patients with hyperlipemia and 26 normal controls were enrolled in this study. Patients with hyperlipemia were randomly divided into 2 groups: a simvastatin treatment group (20 mg/d) and a control group (without simvastatin treatment). Twenty-six healthy people were served as normal control group(n=26).The corrected IBS values(C-IBS) in carotid arteries,the intima-media thickness (IMT), and the serum MMP-9 levels were measured in the normal control group and the patients with hyperlipemia before and 8 weeks after the simvastatin therapy.
RESULTS:
The C-IBS of the simvastatin treatment group and the control group was significantly lower than that in the normal control group (all P<0.05). The IMT and MMP-9 in the simvastatin treatment group and the control group were significantly higher than those in the normal control group (all P<0.05). There was a negative correlation between the C-IBS of carotid arteries and the serum MMP-9 levels in the patients with hyperlipemia (r=-0.76,P<0.05). Eight weeks after the simvastatin treatment, the serum MMP-9 levels decreased significantly(P<0.05).
CONCLUSION
There is a negative correlation between the decreased C-IBS of carotid arteries and the increased serum MMP-9 levels in patients with hyperlipemia.The decreased C-IBS of carotid arteries and the increased serum MMP-9 levels may be the early indicators of atherosclerosis in hyperlipemia patients. The anti-atherosclerosis effect of simvastatin may partly attribute to its ability to lower the serum MMP-9.
