Objective To evaluate the value of clinical findings and different diagnostic criteria for the diagnosis of adult onset Still's disease (AOSD). Methods The AOSD patients admitted to Zhongshan Hospital affiliated to Fudan University from 2003 to 2009 were enrolled. Non-AOSD patients with fever were selected. Different diagnostic criteria of AOSD were applied to all patients. Two indenpendent samples t test and wilco-xon test were used for statistical analysis. Results The clinical features such as rash, arthralgia, arthroncus, sore throat, myalgia, lymph node enlargement, hepatomegaly, splenomegaly, leuko-cytosis, neutrophil ≥80% and serum level of ferrin≥ 2000 ng/ml hadhigher specificity (65.87%~98.41%) with 2.00～5.00 of the positive likelihood ratio.High fever ( ≥39.0℃), negative of ANA and RF had higher sensi-tivity (85.25%~93.65%). Combinations of three parameters such as high fever, rash, sore throat, leukocy-tosis, arthralgia had higher positive likelihood ratio. The specificity of ARA criteria was the highest. The sensitivity and accuracy of Yamaguchi criteria were the highest. Conclusion There is no single parameter that could be specific to the identification of AOSD. Combing with several parameters can improve the diagnostic efficiency. The results of this study have shown that the commonly used diagnostic criteria has high specificity.

Adjuvant and neoadjuvant therapy are the important therapeutic methods for rectal cancer.Neoadjuvant concurrent chemoradiotherapy and postoperative adjuvant chemotherapy play a crutial role in rectal cancer treatment.New chemotherapy drugs and targeted therapy drugs could further improve the therapeutic effect of rectal cancer.

OBJECTIVE:To study the preventive and therapeutic effects of Xinmaitong tablets on model rats with atherosclero-sis (AS) and corresponding mechanism. METHODS:48 rats were randomized into normal group,model group,positive group (simvastatin tablets,2 mg/kg)and the groups of high,medium and low-dose(500,250,125 mg/kg)Xingmaitong tablets,with 8 rats in each group. The rats in all groups except for the normal group were fed high fat diets and given vitamin D3 ip for the estab-lishment of AS model. Meanwhile,the rats in the drug administration groups were given corresponding drugs ig,while those in the normal group and the model group were given normal saline ig,once a day,for 10 consecutive weeks. The levels of cholesterol (TC),triacylglycerol(TG),nitric oxide(NO)and endothelin 1(ET-1)in serum were determined. The pathological change of the aorta tissue was observed under the light microscope,and the size of the aortic atherosclerotic plaque and intima thickness were measured. RESULTS:Compared to the normal group,the rats in the model group had significantly higher levels of TC,TG and ET-1 in serum,a markedly larger aortic atherosclerotic plaque,remarkably thicker intima and much lower level of NO(P<0.01);and obvious aortic atherosclerotic plaque formation was found. Compared to the model group,the above-mentioned indexes of the rats in all drug groups all improved obviously (P<0.05 or P<0.01),except that the decrease in TC in serum of the rats in the group of low-dose Xinmaitong tablets was not significant,which were positively correlated with dose;and the aortic lesion in drug groups was found to be improved. CONCLUSIONS:Xinmaitong tablets have certain preventive and therapeutic effect on the model rats with AS by a mechanism which may be related to the reduction in lipid deposition and the size of an atherosclerotic plaque,the improvement in NO/ET balance and the alleviation of an endothelial injury.

Programmed cell death 5(PDCD5)is a new kind of programmed cell death regulation and control gene. PDCD5′s expression is widespread,and evolution is conservative. PDCD5 has the effect of promo-ting a wide variety of tumor cells to apoptosis and inhibiting proliferation,such as lung cancer,liver cancer et al. Several laboratories′ discoveries show that PDCD5′s expression is significantly decreased when in some dis-ease cases,especially in tumor cases. PDCD5,which is related to the clinical relevance of the tumor,has a great clinical value of discovering,diagnosis and treatment of the tumor.

Objective To explore the expression and significance of galectin-3 in COPD and lung cancer.Methods Sixty female SD rats were randomly divided into three groups:COPD group,lung cancer group and the control group with 20 rats in each group.COPD group was given tracheal injection of lipopolysaccharide and exposed to daily cigarette to establish the model.Lung cancer group was injected with 3,4-benzopyrene-corn mixture.The control group was fed normally.After 20 weeks,plasma galectin-3 concentration was assessed in each group using ELISA method.Results The galectin-3 average concentrations of COPD group,lung cancer group and the control group were (8.63 ± 0.46) ng/mL,(9.15 ± 0.69) ng/mL and (4.47 ± 0.51) ng/mL.The average concentrations in COPD and lung cancer groups were higher than that of the control group with a statistically significant difference (P＜0.05).Conclusion As expressed in COPD and lung cancer,galectin-3 may own a great significance to the occurrence,development and prognosis of COPD and lung cancer.

Objective To prepare cetuximab-β-glucosidase conjugates and to identify its enzymatic activity and an?tibody activity. Methods Cetuximab andβ-glucosidase were crosslinked by Sulfosuccinimidyl-4-(N-maleimidomethyl) cyclohexane-1-carboxylate (Sulfo-SMCC). Cetuximab-β-glucosidase conjugates and its enzymatic and antibody activity were examined by non-reduced SDS-PAGE, colorimetry and indirect immunofluorescence assay. Results We can see clear bands ofβ-glucosidase, cetuximab, cetuximab-β-glucosidase conjugates through electropherogram. Although the en?zymatic activity of cetuximab-β-glucosidase conjugates was lower than that ofβ-glucosidase (U/L:672.97±46.19 vs 869.50± 57.28,t=5.972,P<0.05) shown by colorimetry assay, it still maintain good enzymatic activity. Under fluorescence micro?scope, we can see the conjugates interacted with human bladder cancer EJ cells are in a red fluorescence. Conclusion Ce?tuximab,β-glucosidase were crosslinked successfully by Sulfo-SMCC without altered its enzymatic and antibody activity.

Objective To study the pre-existing intimal hyperplasia and the expression of nuclear factor-κB (NF-κB) and vascular cell adhesion molecule 1 (VCAM-1) in great saphenous vein(GSV) among the patients with diabetes mellitus undergoing coronary artery bypass grafting(CABG).Methods Segments of GSV were collected from 20 patients with diabetes mellitus and 22 patients without diabetes mellitus undergoing CABG.Morphometric analysis was performed after hematoxylin-eosin (HE) staining and Masson staining by microscopic computer analysis.Immunohistochemistry staining was used to examine the expression of NF-κB and VCAM-1 in intima.Results Pre-existing intimal hyperplasia was more common and server in GSV of the patients with diabetes mellitus.The expression of NF-κB and VCAM-1 were significantly higher in intima of GSV in patients with diabetes mellitus than patients without diabetes mellitus.The expression of VCAM-1 was positively related to NFκB in intima of GSV.Conclusion The pre-existing intimal hyperplasia and the expression of NF-κB and VCAM-1 were more common and server in GSV of the patients with diabetes mellitus than patients without diabetes mellitus.This can partially explain the poor prognosis of patients with diabetes mellitus after CABG.

Collateral disease theory has been applied to investigate the pathogenesis of chronic dermal ulcer in traditional Chinese medicine. It is suggested that deficiency of vital qi is the pathological basis of chronic dermal ulcer with collaterals stagnation as the major pathological factor, and collaterals impairment by toxin evil is the main pathological change. The important principle in treatment of chronic dermal ulcer is established as strengthening the body resistance, dredging collaterals and removing toxins, and this enriched the theory of wound healing in traditional Chinese medicine, and has practical value.
