OBJECTIVETo study the effect of nadroparin in the migration of breast cancer cells MDA-MB-231 and its action mechanism.

METHODThe MTT test was adopted to observe the effect of different concentrations of naringenin on the growth capacity of breast cancer cells MDA-MB-231. Wound healing and transwell experiment analysis were conducted to detect the effect of naringenin on the migration of breast cancer cells MDA-MB-231. Western blotting was adopted to investigate the effect of naringenin on protein expressions of MDA-MB-231 cell Integrin β3, β1 and matrix metalloproteinase MMP-2 and MMP-9. The computer virtual docking technique was used to evaluate the combining capacity of naringenin and Integrin β3 in vitro.

RESULTNaringenin inhibited the migration of MDA-MB-231 cells in a dose-dependent manner. In wound healing and transwell experiments, with the increase in the concentration of naringenin, the number of migrant MDA-MB-231 cells and the invasion capacity of breast cancer cells decreased. Naringenin could inhibit the protein expression of Integrin β3 in a dose-dependent manner, but with unobvious effect on expression of Integrin β1. Besides, naringenin could significantly inhibit the protein expressions of MMP-2 and MMP-9. The results of the computer virtual docking showed a negative value in the combining capacity between naringenin and Integrin β3, indicating the high affinity between them.

CONCLUSIONNaringenin can inhibit the growth capacity of breast cancer cells MDA-MB-231 and block the migration and invasion of breast cancer cells MDA-MB-231. Its mechanism is to down-regulate MMP-2 and MMP-9 expressions after combining with Integrin β3.

Objective To explore the diagnostic value of indirect magnetic resonance(MR) arthrography in detecting meniscus tears of the knees.Methods Routine plain MR of the knees followed by indirect MR arthrography was performed in 56 knees with suspected meniscal tears clinically.All cases had subsequently arthroscopic examination or operation.The sensitivity and diagnostic accordance of routine plain MR and indirect MR arthrography were compared based on the result of arthroscopic examination or operation. Results The signal intensity in the area of meniscal tears on image of indirect MR arthrography was obviously higher than that of routine plain MR.The diagnostic accordance rate of indirect MR arthrography was 78.67% while the routine plain MR was 52.20%,and the difference was statistically significant(?~2=21.066,P

AIM: To study the correlation between the drug effects and serum HPLC fingerprint from active compositions of Radix paeoniae alba and Radix et Rhizowa Glycyrrhizae. METHODS: Orthogonal design of L_9(3~4) of the different combinations of three active compositions of paeoniflorin,glycyrrhiza flavoues and Glycyrrhizic acid were prepared,antalgic pharmacological experiments of mice were carried out.The fingerprints of the serum were tested by HPLC method and different chromatographic peaks were obtained.Correlation analysis was applied to interelationship between the area of each peaks and the pharmacologic data. RESULTS: Correlation coefficients were different between pear areas and analgetic coffec. CONCLUSION: This study provides a significant try of investigating the compatibility of composite herbal medicines.

Surgical resection has been accepted as a radical therapy for patients with colorectal cancer, but most of them will develop regional recurrence or distant metastasis. With the development and improvement of novel drugs and methods, they will bring survival hope to patients. In this article, we review the developments in chemotherapy for patients with advanced colorectal cancer.

Objective To observe the clinical effects of endoscopic great saphenous vein harvesting(ESVH) in coronary artery bypass grafting. Methods Endoscopic great saphenous vein harvesting was performed in 89 patients undergoing coronary artery bypass grafting(CABG) from April 2004 to May 2005.An incision 2 cm in length was made on the knee joint and the great saphenous vein was harvested using the VasoView-5 system.Clinical data of the 89 patients(Endoscopic Group) were compared with another 38 patients undergoing conventional great saphenous vein harvesting for CABG from April 2003 to March 2005(Conventional Group) in respect of complications of the leg, the recovery time to walking,and the patency rate at 6 postoperative months.Results The number of harvested vein grafts in the Endoscopic Group was 2~3(mean,2.6).Complications of the leg were significantly less in the Endoscopic Group(6/89) than in the Conventional Group(8/38)(?~2=4.197,P=0.040).The occurrence of pain and numbness of the leg was 7/89 in the Endoscopic Group and 36/38 in the Conventional Group(?~2=89.740,P=0.000).The occurrence of swelling of the leg was 9/89 in the Endoscopic Group and 30/38 in the Conventional Group(?~2=59.299,P=0.000).The recovery time to walking was significantly shorter in the Endoscopic Group(2.3?0.9 d) than in the Conventional Group(3.4?1.6 d)(t=-4.952,P=0.000).There was no significant difference in the patency rate at 6 postoperative months between the Endoscopic Group(96.0%,48/50) and the Conventional Group(95.3%,19/20)(?~2=0.000,P=1.000).Conclusions Use of endoscopic vein harvesting in coronary artery bypass grafting decreases the incidence of postoperative leg-wound infections,post-operative pain,and length of hospital stay.

AIM: To study the change of blood lipid and difference of expressed gene in chest aorta cells of atherosclerosis model rats with or without the treatment of Taishan Ganoderma Lucidum amylose.METHODS: The concentrations of triglyceride (TG), total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C) in serum were measured by automatic serum biochemical assay. Differential-display reverse transcription-PCR (DDRT-PCR) was used to analyze the differential expressed gene in chest aorta cells of atherosclerosis model rat with or without the treatment of Taishan Ganoderma Lucidum amylose. The differential expressed cDNA was confirmed by reverse Northern blotting.RESULTS: Up-regulated and down-regulated cDNA were isolated in chest aorta cells of atherosclerosis model rats with or without Taishan Ganoderma Lucidum amylose treatment. The known up-regulated genes included cytB561, ERP72, nitric oxide synthase 2 and Gpx1. The known down-regulated genes included thymosin β4, FGFRI oncogene, ICAM-1, FK506 binding protein, c-myc and TNF-α. CONCLUSION: Taishan Ganoderma Lucidum amylose decreases the level of blood lipid.

Objective To investigate the red blood cell in urine after kidney puncture and know the best detection method.Methods Collected three urines of 31 patients after kidney puncture and detected the red blood cell by UF-100 and the hemoglobin by urine dipstick test.At the same time,detect the conductivity of the urine by UF-100.Results Both the UF-100 and urine dipstick test could reflect the decrease of red blood cell after kidney puncture.But both of them had some limits.Sometimes the results of the two method were not relative(κ=0.148).The agreement of two methods was 0.538.Neither of them could reflect the bleeding of the kidney accuracy.Conclusion By the best,we should use both the UF-100 and the urine dipstick test to detect the red blood cell in urine after kidney puncture,at the same time we should consider the conductivity of the UF-100.
