Objective To investigate the relationship between plasma concentration of osteopontin (OPN) and disease activity in systemic lupus erythematosus (SLE).Methods The plasma concentration of OPN in 28 healthy controls and 38 SLE patients was measured by enzyme-linked immunosorbent assay. Results The plasma concentration of OPN was significantly higher in SLE patients compared to that in the healthy controls (420?203 ng/mL vs 73?14 ng/mL,P＜0.001),in the patients with proteinuria com- pared to that in the patients without proteinuria (623?88 ng/mL vs 288?135 ng/mL,P＜0.001),in the patients with active disease compared to that in those with inactive disease (529?143 ng/mL vs 185?66ng/mL,P＜0.001),in the patients before treatment compared to that in the patients after treatment (556?130 ng/mL vs 142?22 ng/mL,P＜0.001).The plasma concentration of OPN in patients with arthritis was not different from those without arthritis (489?153 ng/mL vs 375?222 ng/mL,P＞0.05).Plasma concentration of OPN showed a significant positive correlation with systemic lupus erythematosus disease ac- tivity index (SLEDAI) (r=0.93,P＜0.001),but a significant negative correlation with serum C3 level (r=-0.49,P＜0.05).There was no correlation between plasma concentration of OPN and antinuclear an- tibody titre,erythrocyte sedimentation rate,or serum level of C4.Conclusions These data show that plas- ma OPN level has some correlation with the SLE activity,renal damage and progression or amelioration of SLE.OPN could be involved in the pathogenesis of SLE.

Objective To reveal the effects of cold-dryness and modified Zhisou Power on epidermal growth factor receptor (EGFR) and neutrophil elastase (NE) in rats with COPD. Methods COPD model was established with an elastase dose into the trachea combined with exposure to smoking for 90 d; cold-dryness COPD group was further developed by exposure to a cold, dry environment for 90 d. After 90 days, cold-dryness COPD rats was divided into cold-dryness group and Zhisou Power intervention group (treated with modified Zhisou Power for 7 days). On the 97th day, all rats were killed. Pathological changes in lungs were observed. mRNA and protein expression of EGFR were measured by RT-qPCR and Western blot, and the amount of NE in serum and BALF were examined by ELISA. Results EGFR mRNA and protein expression were significantly higher in COPD group, cold-dryness group and Zhisou Power intervention group than in control group. EGFR was significantly lower in Zhisou Power intervention group than in COPD group and cold-dryness group. NE was significantly higher in serum and BALF in COPD group, cold-dryness group and Zhisou Power intervention group than in control group. NE in BALF was significantly higher in cold-dryness group than in COPD group. NE in BALF was significantly lower in Zhisou Power intervention group than in cold-dryness group. Conclusion Modified Zhisou Power can down-regulate the expression of EGFR and the mount of NE in cold-dryness COPD rats to treat COPD.

Objective To study the effect of glucagon-like peptide-1 agonist(exendin-4)on insulin signaling pathway in skeletal muscle of mice with insulin resistance(IR). Methods Thirty male KM mice were divided into normal control group(NC group, n=10)and IR group(n=20). The mice in NC group and IR group were fed with routine diet and high-fat diet for 16 weeks, respectively. After IR models were successfully established, 10 mice in IR group were treated with exendin-4(Ex group, 3μg·kg-1·d-1)for 4 weeks. NC group and IR group were given the same dose of normal saline. Body weight, fasting blood glucose(FBG), and fasting insulin(FINS)were measured before and after the intervention, and homeostasis model assessment for insulin resistance ( HOMA-IR ) was calculated . The muscle glycogen content were measured by Periodic Acid-Schiff Stain ( PAS ) . The expressions of insulinreceptor(IRC), insulin receptor substrate-1(IRS-1), and phosphatidylinositol 3-kinase(PI3K)in the skeletal muscle were measured by Western blot and immunohistochemistry. Results Before intervention, the body weight, FBG, and HOMA-IR of IR group and Ex group were higher compared with NC group(all P<0. 05), but FINS did not rise significantly(P>0. 05). Compared with before intervention, the body weight of three groups after intervention were all increased, but increased more significantly in the IR group. After intervention, the FBG and HOMA-IR in Ex group decreased, compared with IR group and Ex group of non-intervention (all P<0. 05), but FINS did not decrease significantly(P>0. 05). The skeletal muscle cells in NC control were colored extensively and more colored granules, while IR group were less colored, and Ex group were between NC group and IR group. Compared with NC group, the expressions of IRC, IRS-1, and PI3K in the skeletal muscle of IR group were significantly decreased(P<0. 05), not in Ex group(P>0. 05). Compared with IR group, the expressions of IRC, IRS-1 and PI3K in Ex group were higher(P<0. 05). Conclusions Exendin-4 improves insulin resistance by up-regulating the expressions of IRC, IRS-1, and PI3K in the skeletal muscle and promoting the synthesis of muscle glycogen.

Objective To search for the methods of inducing the high stability rat middle cerebral artery occlusion (MCAO) model and to noninvasively assess the method of model effect. Methods Six kinds of filaments with different diameters were used to induce rat MCAO models and their success rate, incidence of subarachnoid hemorrhage, and infarct volume were compared. The model scores were performed to assess the model effect after the operation and at 24 hours after reperfusion. Results Higher model success rate and lower incidence of subarachnoid hemorrhage were achieved when the 0. 28 mm in diameter and 0.32-0.34 mm in tip diameter filaments were used. 1he sensibility and specificity were higher when the model scores were performed at 24 hours after reperfusion. Conclusions Using the filaments of 0.28 mm in diameter and 0. 32-0. 34 mm in tip diameter for intraluminal thread could improved the stability of the models. The model scores at 24 hours after reperfusion could noninvasively assess the model effect.

0.05).Conclusion Both PTX plus DDP and NVB plus DDP are effective to advanced breast cancer.There are no significant difference between the two groups.The two regimens can be applied to the first line chemotherapy.

The probable mechanism of the reduction of rat cerebral ischemic-reperfusion injury by propyl gallate was studied. Intraluminal suture middle cerebral artery occlusion model of rat was employed. Propyl gallate was injected immediately after the ischemia was happened. The activity of NF-kappaB, and the expression of COX-2 and HSP70 on the peripheral ischemia were determined by Western blotting. The expression of TNF-alpha was determined by ELISA assay. RT-PCR and immunofluorescence staining were employed to detect the transcription and expression of TLR-4. Results showed that propyl gallate could inhibit the activity of NF-kappaB in the peripheral ischemia, and reduce the expression of COX-2 and TNF-alpha. As the upstream of NF-kappaB, the transcription and expression of TLR-4 decreased, as well as HSP70, the endogenic ligand of TLR-4. As an antioxidant, propyl gallate could reduce the cerebral ischemic-reperfusion injury through inhibiting the activity of NF-kappaB and decreasing the COX-2 and TNF-alpha in the peripheral ischemia. It also could influence HSP70 and TLR-4.

A series of noscapine analogues have been synthesized via 13-step reaction starting from 2-hydroxy-3-methoxybenzaldehyde. Anti-tumor activities of these compounds were evaluated against HL-60 cell lines in vitro by the standard MTT assay. It was found that most of these derivatives showed appreciable inhibitory activity against HL-60 and tubulin polymerization. The results also indicated that the potency of compound 31 is about three times more than that ofnoscapine against HL-60 cell line and tubulin polymerization. Moreover, it induced a massive accumulation of cells in G2/M phase. These results showed noscapine and its derivatives were worth to be intensively studied further.
