OBJECTIVE: To prepare fumeisong cream and establish its quality control method. METHODS: Ingredients including carbamide, triamcinolone acetonide acetate, camphor, and laurocapram were mixed in an oil-in-water matrix for preparation of fumeisong cream. HPLC was adopted to determine the content of triamcinolone acetonide in the cream. RESULTS: The prepared cream was white in color, with test items all in line with specifications stipulated in 2005 version of China Pharmacopoeia. The linearity concentration range of triamcinolone acetonide was 2.06～20.6 ?g?mL-1(r=0.999 6) and the average recovery rate was 99.6% (RSD=1.0%,n=9). CONCLUSION: The cream is simple and feasible in preparation techniques, and its quality is stable and controllable.

Objective To detect 5′CpG island methylation of APC(adenomatous polyposis coli) gene promoter region in cervical carcinoma cell lines (HeLa,CaSki,SiHa), and to investigate the possibility of Hydralazine in restoring the expression of APC gene through demethylation. Methods The CpG island methylation status of APC gene promoter region of the cervical carcinoma cell lines were analyzed using methylated specific polymerase chain reaction (MSP). The mRNA expression profile of APC gene was analyzed by using RT-PCR after Hydralazine treatment. Results The CpG island of APC gene was methylated in HeLa and hemimethylated in CaSki but not in SiHa. The mRNA expression of APC gene can be detected after hydralazine treatment. Conclusion The APC gene non-expression in cervical carcinoma is associated with CpG island methylation in APC gene promoter region. Hydralazine, served as a demethylating agent, enables to restore the expression of APC gene.

BACKGROUND:It has been shown to exhibit the increase of free radical has relationship with exercise-induced skeletal muscle injury.As a kind of antioxidant,vitamin E has the ability of removing radicals,which can relieve antioxidase damage,and delay fatigue,eventually,improve the motor ability.OBJECTIVE:From the angle of free radical metabolism,to explore the effect of vitamin E on malondialdehyde(MDA)and superoxide dismutase(SOD)of mitochondria in skeletal muscular cell after eccentric exercise,additionally,to clarify the mechanism of vitamin E on reducing the skeletal muscle damage.DESIGN,TIME AND SETTING:The randomized grouping experiment of animal was carried out in the Key Laboratory of General Administration of Sport of China in Shenyang Sport University and the Key Laboratory of China Medical University from May to October in 2007.MATERIALS:A total of 48 male,Sprague Dawley rats,weighing(304?12)g were randomly divided into the of control,sport,physiological saline,and vitamin E groups,with 12 animals in each group.METHODS:Rats in the vitamin E group was administered(i.p.)1-1.2 mg/kg vitamin E capsules once per eight hours,four times one day before experiment,and the amount of injecting volume was 4 mL/kg.The rats in physiological saline were injected by physiological saline,with the same injection methods of the vitamin E group.The models of injury were established by a bout of exhaustive eccentric exercise on a treadmill.After exercise,triceps brachiies were moved from the right side of rats.MAIN OUTCOME MEASURES:The content of MDA and activity of SOD were measured with the reagent-boxes and 6010 UV-seen spectrophotometer.RESULTS:The values of MDA,SOD of mitochondria in triceps brachiies cells in each group were greatly increased after 24 hour eccentric exercise(P 0.05),the value of MDA in the vitamin E group was greatly decreased(P

BACKGROUND: Magnitude and action ways of flow shear stress are important for the endothelialization of small diameter tissue-engineered vessels (TEV), and the TEV resistance ability to blood flow even decides the destiny of implantation. There are many studies on how to construct the TEV and improve anticoagulant ability of TEV after host cell implantation, but the effects of different flow shear stresses on the TEV endothelialization is rarely reported, which may be helpful for increasing the success rate of TEV implantation. OBJECTIVE: To compare the effects of flow shear stresses in single level or stepwise increased on the endothelialization of small diameter TEV and to optimize the TEV in the aspects of shear stress magnitude and loading method. METHODS: The number, morphology and adhesion ability of endothelial cells on the inner wall of TEV were observed through silver nitrate and F-actin staining. RESULTS AND CONCLUSION: Single-level shear stress at 2.5, 3.0 N/m2 for 2 hours removed almost all the endothelial cells seeded on the inner wall of TEV. In contrast, stepwise increased shear stress from 0.5 N/m2 to 3.0 N/m2 at an increase of 0.2 N/m2/2 hours maintained the integrity and oriented along the flow direction, and could induce stress fibers productionin endothelial cells. These results suggest that the stepwise increased flow shear stress can improve the endothelialization of TEV.

Microvesicles (MVs) is small membrane vesicles released from different cell types under different conditions.Studies have shown that MVs may mediate vascular inflammation,angiogenesis,and other pathological processes.MVs may play an important role in the pathogenesis of diabetic retinopathy (DR) by mediating endothelial cell injury,thrombosis and neovascularization.The plasma MV level may be an effective parameter to monitor the development of DR.This article will summarize the research progress of the relationship between MVs and DR in recent years.

Purpose To study the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI),diffusion tensor imaging (DTI) and the combination of these two techniques in benign and malignant nodules of central prostate gland.Materials and Methods Forty-nine patients with nodular abnormal signal in central prostate gland who had accepted prostate MRI scan in Shihezi University Medical College First Affiliated Hospital from September 2015 to December 2016 were retrospectively analyzed,and all the subjects had accepted MRI T2WI,DTI and DCE scan.The pathological results confirmed that there were 21 prostate cancer (PCa) and 36 benign prostatic hyperplasia (BPH) among 57 central gland nodule samples.The fractional anisotropy value,apparent diffusion coefficient value,time to peak,SImax,the curve slope and timesignal intensity curve of nodules were respectively detected,the differences of the parameters between PCa group and BPH group were compared,and receiver operating characteristic (ROC) curve analysis was carried out.Results The difference of fractional anisotropy value,apparent diffusion coefficient value,time to peak and R between PCa group and BPH group was statistically significant (P＜0.05),and there was no significant difference in SImax (P＞0.05);the time-signal intensity curve type of PCa group was mainly in the form of fast-increasing and then decreasing,while the curve type of BPH group was mainly in the form of platform.The area under the ROC curve of DCE,DTI and the combination of DEC and DTI were 0.87 (95％ CI:0.751-0.942),0.85 (95％ CI:0.734-0.933) and 0.94 (95％ CI:0.837-0.983),respectively.Conclusion In the cases of diagnosing benign and malignant nodules of central prostate gland,the accuracy of DTI and DCE was lower than that of the combination of these two techniques,and the diagnostic effect of DTI combined with DCE was better.
