OBJECTIVE:To prepare rapid-disintegrating oral tablets of indometacin and establish a method for its quality control.METHODS:The formula of the oral tablets was optimized by orthogonal test with the formula quality of CMS-Na(A),L-HPC(B),MCC(C),manniton(D) as factors,and the disintegrating time as index.The content of indometacin was determined by ultraviolet spectrophotometry.RESULTS:The optimal formula of the tablets was the following,A∶B∶C∶D=5∶5∶50∶5.The preparation was white in color and its quality was up to the related standard specified in Chinese Pharmacopeia (2005 edition) in identification.The linear range of indometacin was 2.08～41.6 ?g?mL-1 (r=0.999 9).The average recovery was 99.3%.The intra-day RSD=0.53% and inter-day RSD=0.74%.CONCLUSION:The preparation is simple and feasible in preparation process,and controllable in quality.

OBJECTIVE:To investigate the inhibitory effect of ligustrazine on the formation of macrophage-derived foam cells and its possible mechanism. METHODS:Human acute mononuclear cells (THP-1) were incubated with 160 nmol/L phorbol ester (PMA) for 24 h to differentiate into macrophages;and the macrophages were incubated with oxidized low-density lipoprotein (ox-LDL)culture solution containing 80 mg/L for 24 h to differentiate into macrophage-derived foam cells. And then the cells were randomly divided into blank control group(ox-LDL),model(AngⅡ)group,positive control(valsartan)group,and ligustrazine low,medium and high concentration groups(the mass concentration were 0.025,0.05 and 0.1 g/L). After all cells were respective-ly incubated with 80 mg/L ox-LDL culture solution for 48 h,oil red O staining was adopted to observe the transformation rate of foam cells,enzyme chemical method was used to determine the content of cholesterol,and real-time quantitative polymerase chain (RT-PCR)and Western blot were conducted to detect expression levels of Acyl-coenzyme A cholesterol acyltransferase-1(ACAT-1) mRNA and its protein. RESULTS:Compared with blank control group,the transformation rate of foam cells and content of choles-terol in model group were increased,and the expression levels of ACAT-1 mRNA and its protein were obviously strengthened,with significant differences(P<0.01 or P<0.05). Compared with model group,the transformation rate of foam cells and content of cho-lesterol in positive control group(valsartan)and ligustrazine low,medium and high concentration groups were decreased,and the expression levels of ACAT-1 mRNA and its protein were obviously weakened,with significant differences (P<0.01 or P<0.05). CONCLUSIONS:Ligustrazine can inhibit the macrophages differentiating into foam cells,by a mechanism that may be related to inhibiting expression of ACAT-1,and reducing content of cholesterol to reduce formation of foam cells.

ABSTRACT:Objective To investigate the effects of poly ADP-ribose polymerase (PARP ) inhibitor 3-aminobenzene (3-AB)on the delayed development cerebral vasospasm (DCVS)after subarachnoid hemorrhage (SAH)and on the inflammatory factors,namely monocyte chemotactic protein 1 (MCP-1 )and hypersensitive c-reactive protein (hsCRP),and to explore the relationship between these and the signaling pathway of NF-kappa B (NF-κB).Methods Eighty male Sprague-Dawley rats were randomly divided into four groups:normal group (n =8),sham-operation group (n =8),SAH model group (n =32)and 3-AB group (n =32).We established 64 SAH model animals by double injection of blood into the cisterna magna.Half of the SAH model animals were treated with 3-AB by intraperitoneal injection (30 mg/kg).These rats were killed to obtain specimens respectively at days 3, 5,7 and 14 after the second blood injection.The morphological changes of basilar arteries were observed under the light microscope.The contents of PARP,MCP-1 and hsCRP in brain tissues were detected with enzyme-linked immunosorbent assay (ELISA).The expression of NF-κB in basilar arteries was determined by immunohistochemistry.
Results Compared with those in the sham-operation group,the degree of basilar artery spasm reached the peak [(30.47±3.89)%]at day 5 after established SAH model;the thickness and diameter of basilar artery were (1 6.44 ±1.32)μm and (1 78.21 ± 1 1.13)μm,respectively.Cerebral blood flow was reduced by nearly 60% (P <0.01 ). The expression of NF-κB in the cytoplasm and nucleus and PARP content in brain tissue were both increased significantly (P < 0.01 ).MCP-1 [(365.29 ± 28.08 )pg/mL ] and hsCRP [(402.1 6 ± 48.99 )ng/mL ] were significantly enhanced (P <0.01).Compared with the SAH group,after 5 days’intervention with 3-AB,there was obvious alleviation in the spasm degree of basilar artery [(22.65±3.21)%],the thickness [(14.89±1.27)μm]and diameter [(1 98.56±10.91)μm],respectively (P <0.01).Cerebral blood flow was significantly enhanced,but the expression of NF-κB in the cytoplasm and nucleus was decreased and PARP in brain tissue was significantly decreased (P < 0.01 ).MCP-1 [(126.5 1 ± 18.67 )pg/mL]and hsCRP [(285.39 ± 39.07 )ng/mL]in brain tissue were significantly declined,respectively (P <0.01).Conclusion PARP inhibitor 3-AB can alleviate DCVS and inhibit the inflammatory response in brain tissue after SAH.The mechanism may be related to NF-κB signaling pathway.

Purpose To assess the potentia1 of DNA image cytometry and urinary cyto1ogy in screening for urothe1ia1 carcinomas,and to find the idea1 method of ear1y diagnosis of urothe1ia1 cancer. Methods Voided urine specimens from 121 patients with urothe1ia1 carcinoma were random1y co11ected as test group and 95 patients with symptomatic uro1ogic disease but not urothe1ia1 carcinoma as con-tro1 group,a11 of the specimens were ana1yzed by both urinary cyto1ogy and DNA image cytometry. Results Urinary cyto1ogy had a higher sensitivity but 1ower specificity in diagnosis of urothe1ia1 carcinoma than that of DNA cytometry. Urinary cyto1ogy yie1ded an o-vera11 sensitivity of 85. 10%,specificity of 76. 80%. DNA cytometry revea1ed a sensitivity of 81. 80%,specificity of 81. 10%. Among the 121 urothe1ia1 carcinoma,there were 103 b1adder cancers,18 patients with upper urothe1ia1 carcinoma. For different types of urothe1ia1 carcinoma,both of the two methods demonstrated good sensitivity in the high 1eve1 tumor. And DNA cytometry had exce11ent sensitivity in the diagnosis of urothe1ia1 carcinoma in invasive b1adder cancer and upper urinary tract cancer,and both were more than 94%. Conclusions In 1ight of its high1y good sensitivity and specificity in urothe1ia1 carcinoma,especia11y in invasive b1adder cancer and upper urinary tract cancer,DNA cytometry shou1d be used to eva1uate suspect urothe1ia1 ce11s in urinary cyto1ogy specimens. Com-bined with the conventiona1 urinary cyto1ogy,the detection for urothe1ia1 carcinoma wou1d be significant1y improved.
