Objective To study the effect of survivin anfisense oligonucleotides (ASODN)combined with quercetin on proliferation, apoptosis and cell cycle of a hepatocellular carcinoma cell line SSMC-7721 cells. Methods Human hepatocellular carcinoma cell line SSMC-7721 was cultured in vitro,and cells on logarithmic growth phase were used for this experiment. Cell proliferation was measured by MTT assay. The apoptotic rate and cell cycle were examined by flow cytometer (FCM). Morphological change of apoptotic cells were observed by fluorescent microscope. The expression of survivin gene was detected by the method of immunohistochemistry staining and RT-PCR on the mRNA and protein level. Results After sealing survivin gene with ASODN, the proliferation of SSMC-7721 cells was inhibited markedly. FCM analysis showed that there appeared an obvious apoptosis peak after transfection. The inhibitory effect of combined administration of survivin ASODN and quercetin on cell proliferation was much stronger than that of the single way. The result of immunohistochemical and RT-PCR assays showed that survivin ASODN and quercetin inhibited the expression of survivin gene. Conclusion Combined survivin ASODN with quercetin significantly inhibit cell proliferation, down-regulate survivin gene expression and induce the apoptosis of SSMC-7721 cells.

OBJECTIVETo study the influence of different drying methods on the quality of Schisandrae Chinensis Fructus and thus provide useful reference for its proper drying methods.

METHODSchisandrae Chinensis Fructus was processed by eight drying methods including vacuum freeze drying, natural drying in the shade, drying in the sun, oven drying and vacuum drying under different temperature. The contents of the functional ingredients includes chisandrin, gomisin D, gomisin J, schisandrol B, angeloylgomisin H, angeloylgomisin Q, gomisin G, schisantherin A, deoxyschisandrin, schisandrin B, schisandrin C, 5-HMF, total aids and total sugars. The main components change after drying were analyzed by HPLC, ultraviolet spectrophotometry and potentiometric titration. Principal component analysis (PCA) was carried out by SPSS software to evaluate the quality of different processed products from Schisandrae Chinensis Fructus.

RESULTAll these results are in accordance with the requirements of Chinese Pharmacopoeia published in 2010, the contents of schisandrin and total eleven lignans were the highest using vacuum drying, and 5-HMF were the lower, oven drying made little difference but with lower schisandrin and higher 5-HMF as the heat increased.

CONCLUSIONDifferent drying methods have significant influence on the quality of Schisandrae Chinensis Fructus. Oven drying under 5°C should be adopted to substitute drying in the sun according to the China Pharmacopoeia published in 2010 for Schisandrae Chinensis Fructus by comprehensive analysis of the cost, content and practicality.

BACKGROUNDIntravascular ultrasound (IVUS) examination can provide useful information during endovascular stent graft repair. However, its actual clinical utility in thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (type B-AD) remains unclear, especially in complicated aortic dissection. We evaluated the effect of IVUS as a complementary tool during TEVAR.

METHODSFrom September 2011 to April 2012, we conducted a prospective cohort study of 47 consecutive patients with "complicated" type B-AD diagnosed. We divided the patients into two groups: IVUS-assisted TEVAR group and TEVAR using angiography alone group. The general procedure of TEVAR was performed. We evaluated the perioperative and follow-up events. Patient demographics, comorbidities, preoperative images, dissection morphology, details of operative strategy, intraoperative events, and postoperative course were recorded.

RESULTSA total of 47 patients receiving TEVAR were enrolled. Among them (females, 8.51%; mean age, 57.38 ± 13.02 years), 13 cases (27.66%) were selected in the IVUS-assisted TEVAR group, and 34 were selected in the TEVAR group. All patients were symptomatic. The average diameter values of IVUS measurements in the landing zone were greater than those estimated by computed tomography angiography (31.82 ± 4.21 mm vs. 30.64 ± 4.13 mm, P < 0.001). The technique success rate was 100%. Among the postoperative outcomes, statistical differences were only observed between the IVUS-assisted TEVAR group and TEVAR group for total operative time and the amount of contrast used (P = 0.013 and P < 0.001, respectively). The follow-up ranged from 15 to 36 months for the IVUS-assisted TEVAR group and from 10 to 35 months for the TEVAR group (P = 0.646). The primary endpoints were no statistical difference in the two groups.

CONCLUSIONSIntraoperative IVUS-assisted TEVAR is clinically feasible and safe. For the endovascular repair of "complicated" type B-AD, IVUS may be helpful for understanding dissection morphology and decrease the operative time and the amount of contrast used.

We reported a case of multiple type II endoleaks detected by duplex ultrasound after endovascular abdominal aneurysm repair. The patient was undergoing warfarin therapy. Duplex ultrasound was applied as the sole surveillance method during follow-up and provided the concerned information for reintervention. The endoleaks were successfully repaired by coil embolization of the collaterals from the internal iliac artery feeding the fourth lumbar artery.

OBJECTIVETo evaluate the open surgery as well as the endovascular treatment of abdominal aortic aneurysms (AAA) in octogenarians.

METHODSTwenty AAA cases aging from 80 to 90 in the past six years were reviewed. Open surgery on 12 patients and endovascular repair on the other 8 ones were performed.

RESULTSDuring peri-operation, there were 2 mortality from the surgical group among all 20 cases. The endovascular group underwent significantly better operational procedure and complication situation than the surgical one. Eighteen cases were followed up for 3-69 months (average months) except for 2 patients of surgical group. Both group suffered 2 late mortality. The accumulated survival rate were 6/10 in the surgical group and 6/8 in the endovascular group, respectively.

CONCLUSIONSurgical treatment in applicable for octogenarians with AAA. The endovascular repair was preferable to suitable cases.
