Abstract
Hepatocellular carcinoma(HCC) is serious condition associated with a high morbidity and mortality. Therefore is an urgent need to develop novel noninvasive techniques for early diagnosis, particularly for patients with AFP-negative [AFP(-)] HCC. In this study, iTRAQ-MALDI-MS/MS was used to identify differentially expressed proteins in AFP(-) HBV-related HCC compared with non-cancerous hepatitis B virus (HBV) and healthy controls subjects.Serum was obtained from 18 patients with AFP(-) HBV-related HCC, 18 matched patients with HBV without HCC and 18 healthy control subjects. High abundance proteins were removed from serum and the differentially expressed proteins from the three groups were screened out using iTRAQ-MALDI-MS/MS. The Gene Ontology (GO) function and the interaction networks of differentially expressed proteins were then analyzed. A total of 24 expressed differential proteins associated with AFP(-) HBV-related HCC were screened out, 15 proteins were up-regulated and 9 down-regulated. The most common molecular function of the 24 differentially expressed proteins was enzyme inhibition. Interaction network of the 24 differentially expressed proteins showed that 14 proteins (C5, KNG1, FN1, LRG1, HRG, SERPINC1, CRP, APOB, SAA1, APCS, C4BPA, CFI, CFB and GSN) were central to the functional network. The expression levels of the GSN protein were down-regulated in AFP(-) HBV-related HCC subjects compared with healthy controls and the HBV group (p<0.01), consistent with the iTRAQ results.The 14 proteins from the serum of AFP(-) HBV-related HCC appeared at the fulcrum of the functional network and were differentially expressed compare to HBV and healthy controls suggesting a possible association with HCC progression.

Abstract
The G-protein-coupled estrogen receptor 1 (GPER) has recently been reported to mediate the non-genomic action of estrogen in different types of cells and tissues. G-1 (1-[4-(6-bromobenzo[1,3] dioxol-5yl)-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinolin-8-yl]-ethanone) was developed as a potent and selective agonist for GPER. G-1 has been shown to induce the expression of genes and activate pathways that facilitate cancer cell proliferation by activating GPER. Here we demonstrate that G-1 has an anticancer potential with a mechanism similar to vinca alkaloids, the commonly used chemotherapy drugs. We found that G-1 blocks tubulin polymerization and thereby interrupts microtubule assembly in ovarian cancer cells leading to the arrest of cell cycle in the prophase of mitosis and the suppression of ovarian cancer cell proliferation. G-1 treatment also induces apoptosis of ovarian cancer cells. The ability of G-1 to target microtubules to suppress ovarian cancer cell proliferation makes it a promising candidate drug for treatment of ovarian cancer.

Abstract
OBJECTIVE The aim of this study was to examine the effect of ursolic acid (UA) and oleanolic acid (OA), triterpenoid compounds that are isolated from many edible and medicinal plants, on cariogenic microorganisms and biofilms. METHODS A microtitre plate dilution assay was used to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of UA and OA against two Actinomyces spp. and four Streptococcus spp. The antibacterial activity of UA and OA was assessed by crystal violet staining, scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM). RESULTS UA and OA displayed differential antibacterial activities against the six tested bacteria, with UA showing greater antibacterial activity than OA. Furthermore, the two drugs had greater antibacterial activity against Actinomyces spp. than Streptococcus spp. UA and OA at 1/4 MIC can reduce bacterial biofilm formation, whereas higher UA concentrations displayed antibacterial activity against Actinomyces viscosus and Streptococcus mutans in mature biofilms. For instance, 2.0 mg ml(-1) UA was sufficient to kill an A. viscosus biofilm. CONCLUSIONS UA and OA inhibit the growth of cariogenic microorganisms, which suggests that UA and OA have considerable potential as antibacterial agents for dental caries prevention.

Abstract
We analysed the association between influenza A(H7N9) confirmed cases and exposure to poultry in Huzhou city, China. All cases (n=12) had a history of direct exposure to poultry or live poultry markets. We detected A(H7N9)-positive poultry samples from each site that was epidemiologically associated with cases. None of the cases’ close contacts tested positive. After closure of the markets, no new cases were identified, suggesting an epidemiological link between poultry exposure and A(H7N9) virus infection.

Abstract
Aging is one of the greatest risk factors in vascular diseases (VDs). During aging, there are structural and functional changes in the vasculature, including dilated lumen, altered intimal-medial thickness (IMT), vascular stiffness, endothelial dysfunction, increased endothelial apoptosis, matrix metalloproteinase (MMP) dysregulation, increased expression of inflammatory molecules, aggravated oxidative stress and shortened telomere length. These changes leave the body more susceptible to primary hypertension, stroke and coronary artery disease. Molecules that suppress these age-related changes would provide an excellent medical intervention for VDs. Mammalian Sir2 (SIRT1, a NAD+-dependent deacetylase), previously shown to extend the lifespan of lower organisms, is a promising target molecule to influence some aspects of vascular aging. In this review, we summarized roles of SIRT1 in various pathophysiological processes of vascular aging and proposed that SIRT1 and its activators can become novel therapeutic targets for age-related VDs.

Abstract
The aim of this study was to explore the effects of subacute exposure to 1,2-dichloroethane (1,2-DCE) on mouse behavior and the related mechanisms focusing on alteration of oxidative stress and amino acid neurotransmitters in the brain. Mouse behavior was examined by open field test. Levels of nitric oxide (NO), malondialdehyde (MDA) and nonprotein sulfhydryl (NPSH) and activity of inducible nitric oxide synthase (iNOS) and superoxide dismutase (SOD) were determined by colorimetric method. Contents of glutamate (Glu), aspartate (Asp) and gamma-aminobutyric acid (GABA) were evaluated by high-performance liquid chromatography. Reduced locomotor and exploratory activities and increased anxiety were found in 0.45 and 0.9 g/m3 1,2-DCE-treated mice. In contrast, increased excitability was found in 0.225 g/m3 1,2-DCE-treated mice. Compensatory antioxidant status and increased NOS activity and NO level in the brain were found in 1,2-DCE-treated mice. Moreover, Glu contents in 1,2-DCE-treated mice and GABA contents in 0.9 g/m3 1,2-DCE-treated mice increased, whereas GABA contents in 0.225 g/m3 1,2-DCE-treated mice decreased significantly compared with control. Taken together, our results suggested that mouse behavior could be disturbed by subacute exposure to 1,2-DCE, and the changes of amino acid neurotransmitter in the brain might be related to the behavioral effects.

Abstract
We evaluate and report our clinical and angiographic outcomes associated with stent-assisted coil embolization of wide-necked intracranial aneurysms using the Enterprise stent. One hundred sixty-nine patients diagnosed with 182 wide-necked intracranial aneurysms underwent placement of the Enterprise stent between April 2009 and October 2011. Demographic information, procedural data, procedure-related complications, angiographic results, and clinical outcomes were reviewed and evaluated. Stent deployment was successful in 166 out of 169 procedures (98.2%). Four patients had acute procedure-related complications, including th romboembolism in three patients and aneurysm perforation resulting in the death of one patient. Immediate angiographic results showed complete occlusion in 101 aneurysms (56.4%) and near-complete occlusion in 55 aneurysms (30.7%). Follow-up angiography was performed in 108 patients with 119 aneurysms at a mean of 8.1 months: complete occlusion was observed in 95 aneurysms (79.8%) and near-complete occlusion was found in 12 aneurysms (10.1%). Delayed intra-stent thromboses were observed in two patients, and asymptomatic in-stent stenosis was observed in one patient. Ten aneurysms (8.4%, 10/119) demonstrated recanalization, all of which were subsequently recoiled successfully. Clinical follow-up was obtained for 132 patients at a mean of 11.4 months, out of which 118 (89.4%) had favorable clinical outcomes as determined using a modified Rankin Scale (mRS) ≤ 1. The rates of procedure-related mortality and permanent morbidity were 0.6% (1/169) and 2.3%( 3/132), respectively. This study adds to the current body of evidence supporting the Enterprise stent as an effective and safe tool for the treatment of wide-necked intracranial aneurysms because it results in more complete occlusion and lower complication rates.

Abstract
We describe the complications of endovascular embolization for cerebral arteriovenous malformations (AVMs). 164 consecutive patients with AVMs treated by endovascular embolization between 1998 and 2003 were retrospectively reviewed. Over a five-year period, 292 embolization procedures were performed in 164 patients with embolization as the primary treatment modality (n=126) or as an adjunct to surgery (n =14) or radiosurgery (n=24). There were a total of 15 (9.1% per patient, 5.1% per procedure) complications in this series, of which 14 were clinically significant (8.5% of patients, 4.8% per procedure), and one was a technical complication (0.6% of patients, 0.3% per procedure). Excellent or good outcomes (Glasgow Outcome Scale ≥ 4) were observed in 136 (82.9%) patients at discharge. Neurological deficits (Glasgow Outcome Scale 1-4) as a direct result of embolization were 7.3% at discharge. In a single-center, retrospective, nonrandomized study, 82.9% of patients had excellent or good outcomes at discharge after AVM embolization, with a complication rate of 5.1%.

Abstract
AIM To investigate the efficacy and tolerability of vildagliptin as add-on therapy to metformin in Chinese patients with type 2 diabetes mellitus (T2DM) inadequately controlled with metformin. METHODS This was a 24-week, randomized, double-blind, placebo-controlled study. Patients with T2DM (N = 438) with haemoglobin A1c (HbA1c) of 7.0-10.0% and fasting plasma glucose (FPG) <15 mmol/l (<270 mg/dl) were randomized (1 : 1 : 1) to vildagliptin 50 mg bid, vildagliptin 50 mg qd or placebo in addition to metformin. RESULTS The treatment groups were well balanced at baseline [mean HbA1c, 8.0%, FPG, 8.8 mmol/l (158 mg/dl); body mass index, 25.5 kg/m(2) ]. The adjusted mean change (AMΔ) in HbA1c at endpoint was -1.05 ± 0.08%, -0.92 ± 0.08% and -0.54 ± 0.08% in patients receiving vildagliptin 50 mg bid, 50 mg qd and placebo, respectively. The between-treatment difference (vildagliptin 50 mg bid-placebo) was -0.51 ± 0.11%, p < 0.001. A greater proportion of vildagliptin-treated patients met at least one responder criterion (82.1 and 70.7%) compared to placebo-treated patients (60.4%). The AMΔ at endpoint for FPG with vildagliptin 50 mg bid, -0.95 mmol/l (-17.1 mg/dl); 50 mg qd, -0.84 mmol/l (-15.1 mg/dl) was significantly different compared with the placebo -0.26 mmol/l (-4.68 mg/dl) (p ≤ 0.001). Adverse events (AEs) were reported as 34.2, 36.5 and 37.5% for patients receiving vildagliptin 50 mg bid, 50 mg qd or placebo, respectively. Two patients in the vildagliptin 50 mg qd and one in the placebo group reported serious AEs, which were not considered to be related to the study drug; one incidence of hypoglycaemic event was reported in the vildagliptin 50 mg bid group. CONCLUSION Vildagliptin as add-on therapy to metformin improved glycaemic control and was well tolerated in Chinese patients who were inadequately controlled by metformin only.

Abstract
To evaluate the single-centre experience with endovascular management of direct carotid-cavernous sinus fistulas (DCCF). Between November 2008 and November 2010, a total of 14 patients (11 males) with direct carotid-cavernous sinus fistula underwent 16 transarterial treatment sessions. The patient files and angiograms were analysed retrospectively. Clinical signs and symptoms included exophthalmos [n=12, (85.7%)], pulsatile tinnitus [n=9, (64.3%)], cranial nerve III or VI palsy [n=2, (14.3%)], and impaired vision [n=1, (7.1%)]. Angiography revealed in addition cortical drainage in five patients (35.7%). Transarterial embolization was performed using detachable balloon in nine sessions (56.2%), detachable coils in three sessions (18.8%) and a combination with Onyx in four sessions (25%). Complete interruption of the arteriovenous shunt was achieved in all patients. There was a tendency for ocular pressure-related symptoms to resolve rapidly, while cranial nerve palsy and diplopia improved slowly (7.1%) or did not change (7.1%). The patient with visual impairment recovered within the first two weeks after endovascular treatment. After complete interruption of the arteriovenous shunt, two (12.5%) recurrences were observed in balloon treatment and retreatment was given. Transarterial management is a highly efficient and safe treatment in DCCFs. In the majority of patients a significant and permanent improvement in clinical signs and symptoms can be achieved.

Abstract
This paper reports that decompression of the facial nerve by transarterial Onyx embolization may relieve hemifacial spasm (HFS) caused by dilated veins due to a right petrosal dural arteriovenous fistula (DAVF). A 56-year-old man suffered severe chronic right HFS associated with a dilated right petrosal vein lying in the vicinity of the facial nerve. The right petrosal DAVF was reached through the middle meningeal artery using a transfemoral arterial approach and was occluded with Onyx 18 (M.T.I.- ev3, Irvine, CA, USA). There was complete remission of HFS without recurrence after two months of follow-up. This case supports vascular compression in the pathogenesis of HFS and suggests that facial nerve injury caused by a DAVF could be treated with transarterial Onyx embolization.

Abstract
We report on the predictors of seizure presention in unruptured brain arteriovenous malformations (AVMs). Between 1999 and 2008, 302 consecutive patients with AVMs were referred to our institution for endovascular treatment. Seventy-four patients (24.5%) experienced seizures without hemorrhage before treatment. We tested for statistical associations between angioarchitectural characteristics and seizure presentation. When we compared the 74 patients with seizures without hemorrhage with the 228 patients who did not experience seizures initially (total of 302 patients), male sex, cortical AVM location, AVM size of more than 3 cm, superficial venous drainage and presence of varices in the venous drainage were statistically associated with seizures (P=0.016, P=0.002, P=0.022, P=0.005, and P=0.022, respectively). Posterior fossa and deep locations and coexisting aneurysms were statistically associated with no seizures. The angioarchitectural characteristics of AVM associated with seizure presentation include male sex, cortical AVM location, AVM size of more than 3 cm, superficial venous drainage and presence of varices in the venous drainage.

Sixty-three patients with 65 vertebral (both acute dissection and chronic larger aneurysms are included) treated at our hospital form the basis of the analysis. Clinical outcome was evaluated using the modified Rankin Scale. Angiographic follow-up data was obtained for 44 patients (69.8%) for periods ranging from three to 16 months (mean, eight months). Based on the Hunt and Hess grading scale, the patient population included 34 patients (54.0%) with unruptured aneurysms, 28 (44.4%) with Grade 1 aneurysms, one (1.6%) with Grade 2 aneurysms. The locations of the aneurysms included 25 (38.5%) at the distal to posterior inferior cerebellar artery (PICA), 22 (33.8%) at the proximal to PICA and 18 (27.7%) at the vertebral artery-posterior inferior cerebellar artery (VA-PICA). Of the 63 patients, 12 (19%) were women and 51 (81%) were men. The mean age at treatment was 41.7 years (range, six-77 yrs). Follow-up angiograms were obtained in 44 (69.8%) out of 63 patients. Complete or virtually complete thrombosis was confirmed on early posttreatment angiography in 39 (88.6%) out of 44 patients. A slight reduction in the size of the lesion was noted in three patients and there was a significant residual lesion in two (4.5%) patients. Clinical follow-up revealed 90.5% patients in the mRS 0-2 category, 4.8% patients in the mRS>2 category, and 4.8% patients had died (mRS 6). Three patients died of rebleeding (n=1) or progressive mass effect/brainstem ischemia (n=2). Ruptured and unruptured aneurysms of the vertebral artery can be well treated using endovascular techniques, overall long-term results were good in 90.5% of patients.

Abstract
Posterior cerebral aneurysms are rare vascular lesions and usually present as non-saccular or dissecting in nature. We present a retrospective review of our experience in the deliberate parent artery occlusion of posterior cerebral artery (PCA) aneurysms.From June 2006 to June 2010, 12 patients (seven men, five women) with posterior cerebral artery non-saccular aneurysms presented to our department and were treated by parent artery occlusion. There were eight (66.7%) aneurysms located at the P2 segment, two (16.7%) at the P2-3 junction, one (8.3%) at the P1-2 junction and one (8.3%) at the P3 segment. Ten of the 12 patients were treated by aneurysm together with parent artery occlusion and two were treated by proximal occlusion.The procedure was technically successful in all cases. Angiography was performed immediately after the procedure in all patients and showed occlusion of the parent vessel with no filling of the aneurysm. Only one patient (8.3%) developed procedure-related transient hemianopsia and recovered within one month. The other 11 patients showed no additional neurological symptoms after procedure. Deliberate parent artery occlusion by detachable coils appears to be well tolerated for P2 or distal segment of PCA in our limited case series. We propose that this technique could be a good treatment option in treating non-saccular aneurysms in this location.
