International Eye Science 2016;16(7):1386-1388
AIM: To investigate the application value of contrast -enhanced ultrasound ( CEUS) and analysis software for intra-ocular tumor diagnosis.
METHODS:Retrospective analysis for 90 cases (90 eyes) with intra- ocular tumor with CEUS examination, and all cases were confirmed by pathology after surgery or clinical comprehensive diagnosis and follow-up.
RESULTS: Choroidal hemangioma, choroidal melanoma, choroidal metastatic carcinoma had obvious different CEUS enhancement pattern, quantitative analysis indexes of those tumors by imaging analysis software were significantly different (P<0. 05).
CONCLUSION: The CEUS can provide quantitative analysis for intra - ocular tumor with preferable clinical application value.

This research is to investigate study the flavonoids from stems of Nelumbo nucifera and the cytotoxic activities of iso- lated compounds. The constituents were separated by column chromatography,and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for cytoxic activities by MTT method. Twelve compounds were isolated and identified as rhamnazin-3-O-beta-D-glucopyranoside (1), luteolin-3', 4'-dimethylether-7-O-beta-D-glucoside (2), kaempferol-3-O-beta-D-xylopyranosyl-(1-->2)-O-beta-D-glucopyranoside (3), quercetin-3,3'-di-O-beta-D-glucopyranoside (4), 1, 8-dihydroxy-3,7-dimethoxyxanthone (5), isorhamnetin-3-O-beta-D-glucopyranoside(6) , kaempferol(7), isorhamnetin (8), quercetin(9), astragalin(10), hyperoside (11) and 1-hy- droxy-3,7,8-trimethoxyxanthone(12). All compounds were isolated from stems of this plant for the first time, and compounds 1-5 were firstly isolated from the family nelumbonaceae. Compounds 24 and 6 showed significant cytotoxic activities against BEL-7402 carcinoma cell lines at a concentration of 1 x 10(-5) mol x L(-1) with the inhibitory rate of 67.36%, 53.25%, 57.78%, 60.13% and 52.11%, respectively.

9. Effect of physical techniques on in vitro transdermal permeability of sinapine thiocyanate
Journal of International Pharmaceutical Research 2017;44(5):432-436
Objective To compare the improvement effect of three physical techniques on the transdermal absorption of sinapine thiocyanate(ST)in vitro, including microneedles, sonophoresis and iontophoresis, and to evaluate the mechanism and rules of physcial techniques on the transdermal absorption of poorly transdermal absorbed drugs. Methods In vitro transdermal experiment was carried out under the circumstances of microneedles, sonophoresis or iontophoresis, using the modified Franz diffusion pool. The 2 mg/ml ST solution was adopted as the donor solution, and the SD rats′ abdomen skin was used as the model skin. Sampling was carried out at the predetermined time points and each sample was analyzed by HPLC. Cumulative transdermal amount and steady transdermal absorption rate were calculated. Pathological slides were made after the skins were treated with microneedles, sonophoresis and iontophoresis for 12 h. The structure changes were observed to evaluate the transdermal improvement mechanism of different technologies. Results Accumulated transdermal amount of ST was little without any techniques. The transdermal improvement effect of different technologies was as follows: Microneedles>sonophoresis>iontophoresis. A substantial hole formed on the skin by microneedles to promote ST transdermal absorption obviously. Sonophoresis disrupted the tight structure of skin and improved the transdermal absorption of drugs easily. The effect of iontophresis on skin structure was little. Conclusion This study provides experimental evidence for choice of different techniques to improve transdermal absorption.

Objective To study the effects of mitochondrial permeability transition (MPT) on hepatocyte apoptosis and mitochondrial damage,and investigate the effects of curcumin on MPT and the related mechanisms in septic rat.Methods Fifteen healthy male Sprague-Dawley (SD) rats were randomly divided into three groups:sham group,sepsis group and curcumin group,with 5 rats in each group.Septic rat model was reproduced by cecal ligation and puncture (CLP).The rats in sham group were flipped the cecum without perforation and ligation.The rats in the curcumin group were treated with curcumin 100 mg·kg-1·d-1 (dissolved in saline to 10 mL/kg) by oral gavage for 7 days,while the other groups were treated with normal saline.Tissue samples were harvested in each group at 12 hours after operation.Pathological changes in hepatic mitochondria were observed under electron microscopy,concentration of free calcium was examined with confocal laser scanning microscope.After Fluo-3/AM staining,protein and mRNA expression of active caspase-3,Bcl-2 and Bax were examined by Western Blot and reverse transcription-polymerase chain reaction (RT-PCR).Results Under the transmission electron microscope,intact cell membrane,adqulis cytoplasm,and normal and clear mitochondrion was found in the sham group.Mitochondria in sepsis group swelled obviously with mitochondrial cristae broken or disappearance,unclear bilateral membrane structure,while the curcumin group showed much less pathological changes,with few mitochondria swell,and smear bilateral membrane structure.The fluorescence intensity index of sham group,sepsis group and curcumin group was raised successively (417.33 ± 15.88,772.95 ± 42.37,1 560.84 ± 160.78,respectively,F=184.149,P=0.000).The protein and mRNA expression of active caspase-3 and Bax had the highest level in sepsis group,followed by the curcumin group,and that in the sham group was the lowest [active caspase-3 protein (gray scale):1.698 ± 0.061,0.694 ± 0.045,0.246 ± 0.027,F=1 289.667,P=0.000; active caspase-3 mRNA (2-Δ△Ct):1.031 ±0.135,0.578 ± 0.144,0.183 ±0.036,F=66.958,P=0.000; Bax protein (gray scale):1.826 ±0.126,1.254 ±0.140,0.623 ±0.901,F=94.536,P=0.000; Bax mRNA (2-ΔΔCt):2.774 ±0.338,1.661 ±0.226,0.656 ±0.114,F=124.710,P=0.000],all of these values had statistical significance among the three groups (all P<0.01).While Bcl-2 protein and mRNA had the highest level in curcumin group and lowest level in the sham group [Bcl-2 protein (gray scale):0.716 ±0.091,1.328 ±0.147,1.656 ±0.104,F=84.918,P=0.000; Bcl-2 mRNA (2-△ΔCt):0.617 ±0.118,1.393 ±0.096,1.650 ±0.167,F=83.846,P=0.000].The protein and mRNA expressions of Bcl-2/Bax ratio were lowest in sepsis group,then sham group,and highest in curcumin group [Bcl-2/Bax protein (gray scale):0.726 ± 0.055,1.150 ± 0.043,1.333 ± 0.163,F=46.265,P=0.000; Bcl-2/Bax mRNA (2-Δ△Ct):0.505 ±0.041,0.944±0.097,1.006 ±0.168,F=12.211,P=0.001].Conclusions MPT can lead to mitochondrial dysfunction and further cause hepatocyte apoptosis.Mechanism of effect of curcumin on MPT may be related to reduction of intracellular calcium concentration,promotion of anti-apoptotic Bcl-2 gene expression,inhibition of caspase-3 activation and Bax gene.
