Abstract
OBJECTIVES The treatment guidelines for isolated superior mesenteric artery dissection (SMAD) are not well established. The purpose of this study was to report a single-centre series of SMAD and propose treatment guidelines. MATERIALS AND METHODS Between November 2004 and December 2009, 30 patients were diagnosed with SMAD. We retrospectively reviewed their medical records. RESULTS The subjects included 26 men and four women, with a mean age of 55.1 years. The chief complaint was abdominal pain in 17 patients, whereas 13 patients were asymptomatic. The mean follow-up was 38.3 months. The radiographic findings included intimal flap with a false lumen in 20 patients and intramural haematoma in 10 patients. The treatments included observation in 18 patients, anticoagulation in five patients, stenting in six patients and surgery in one patient. During follow-up (mean 15.6 months), there was no change in the computed tomography scans of seven patients, improvement was observed in four patients and complete resolution was observed in four patients. All patients, including the symptomatic patients, remained asymptomatic during follow-up. CONCLUSIONS Most patients with SMAD can be successfully managed with conservative treatment. Surgical treatment or percutaneous intervention can be reserved for patients with severe mesenteric ischaemia and those for whom the initial conservative treatment fails.

Abstract
PURPOSE To evaluate intra-device reproducibility of retinal nerve fibre layer (RNFL) measurements obtained using Stratus and Spectralis optical coherence tomography, and to analyze inter-device correlation and agreement for these measurements. DESIGN Prospective observational study. METHODS A total of 30 normal individuals participated in the study. One eye of each participant was scanned three times during one session by the same operator using Spectralis and Stratus. Intra-class correlation coefficients (ICCs), correlation coefficients (R), and Bland-Altman plots (BAPs) were used to assess reproducibility, correlation, and agreement between the two devices, respectively. RESULTS A significant difference in mean RNFL thickness was seen between Stratus and Spectralis (106.2 ± 6.9 μm vs 100.0 ± 7.3 μm, P = 0.0001). ICCs of RNFL thickness measurements ranged from 0.69 (clock hour 2; 95% confidence interval (95% CI): 0.54, 0.85) to 0.91 (inferior quadrant; 95% CI: 0.86, 0.96) for Stratus and were higher for Spectralis, ranging from 0.87 (temporal-superior sector; 95% CI: 0.79, 0.94) to 0.96 (global and nasal-inferior sector; 95% CI: 0.94, 0.99). Rs of RNFL thickness measurements between the two instruments ranged from 0.61 (temporal quadrant) to 0.87 (superior quadrant). BAPs demonstrated a systematic difference in RNFL values between the two devices, with Spectralis producing thinner RNFL values than Stratus. CONCLUSIONS Spectralis demonstrated higher ICCs and thinner RNFL measurements than Stratus. Although the inter-device correlation was good, differences in RNFL measurements obtained by the two devices indicate that these measurements would not be interchangeable in clinical evaluations.

Abstract
The efficacy of drug-eluting stents (DES) in reducing the rates of in-stent restenosis after percutaneous coronary intervention (PCI) compared to bare metal stents (BMS) in stable coronary artery disease has been well demonstrated. Thus, the Food and Drug Administration has approved the utilization of DES for stable coronary disease. However, there is still much debate surrounding the implantation of DES for patients with ST-segment elevation myocardial infarction (STEMI) given safety concerns about the possibility of increased rates of stent thrombosis with DES. The review of the current body of evidence comparing DES with BMS is consistent with results from previous trials in stable coronary disease and reveals lower rates of revascularization with DES in STEMI patients. The ultimate decision regarding the appropriate stent during PCI needs to be individualized as patients' compliance with dual antiplatelet therapy is critical. The data suggest that PCI with DES in STEMI patients who adhere to long-term dual antiplatelet therapy is safe and effective. Randomized trials with longer-term follow-up are necessary to better elucidate the safety and efficacy of DES versus BMS in patients with STEMI.

Abstract
BACKGROUND This study was designed to assess clinical and functional outcomes associated with switching to duloxetine treatment in patients with major depressive disorder (MDD) experiencing emotional and painful physical symptoms in their current episode. METHODS In this 8-week, multinational, multicentre, single-arm, open-label clinical trial, 242 MDD patients were switched to duloxetine 60 mg/day after selective serotonin reuptake inhibitor (SSRI) or serotonin and norepinephrine reuptake inhibitor (SNRI) treatment. The primary analysis compared mean change from baseline in Brief Pain Inventory-Modified Short Form (BPI-SF) interference score between initial responders [≥ 50% reduction from baseline on the 17-item Hamilton Depression Rating Scale (HAMD(17)) Maier subscale] and initial non-responders after 4 weeks. Initial responders continued with duloxetine 60 mg/day. Initial non-responders received duloxetine 120 mg/day for the remaining 4 weeks. Depression, pain, anxiety and functional outcomes were also compared after 8 weeks. RESULTS BPI-SF interference decreased from baseline in initial responders (n = 108) and initial non-responders (n = 85) after 4 weeks of duloxetine treatment, with greater reductions in initial responders [BPI-SF mean difference in reduction: 1.01 (95% CI 0.42-1.61); p < 0.001]. Reductions in pain interference favouring initial responders were also apparent after 8 weeks [0.68 (95% CI: 0.03-1.33); p = 0.042]. Depression, pain, anxiety and function improved over 8 weeks across patient groups. CONCLUSIONS Elements of core mood and pain are important residual symptoms following poor treatment response in MDD. Early improvement in these symptoms after switching to duloxetine indicated an increased chance of functional recovery.

Abstract
We report a simple and manageable growth method for placing dense three-dimensional Ge quantum dot (QD) arrays in a uniform or a graded size distribution, based on thermally oxidizing stacked poly-SiGe in a layer-cake technique. The QD size and spatial density in each stack can be modulated by conditions of the Ge content in poly-Si(1-x)Ge(x), oxidation, and the underlay buffer layer. Size-dependent internal structure, strain, and photoluminescence properties of Ge QDs are systematically investigated. Optimization of the processing conditions could be carried out for producing dense Ge QD arrays to maximize photovoltaic efficiency.

Abstract
Reflexology is a popular form of complementary and alternative medicine (CAM). The aim of this update is to critically evaluate the evidence for or against the effectiveness of reflexology in patients with any type of medical condition. Six electronic databases were searched to identify all relevant randomised clinical trials (RCTs). Their methodological quality was assessed independently by the two reviewers using the Jadad score. Overall, 23 studies met all inclusion criteria. They related to a wide range of medical conditions. The methodological quality of the RCTs was often poor. Nine high quality RCTs generated negative findings; and five generated positive findings. Eight RCTs suggested that reflexology is effective for the following conditions: diabetes, premenstrual syndrome, cancer patients, multiple sclerosis, symptomatic idiopathic detrusor over-activity and dementia yet important caveats remain. It is concluded that the best clinical evidence does not demonstrate convincingly reflexology to be an effective treatment for any medical condition.

Abstract
Brain-derived neurotrophic factor (BDNF) is a candidate molecule for influencing the clinical response to antidepressant treatment. The aims of this study were to determine the relationship between the Val66Met polymorphism in the BDNF gene and the response to mirtazapine in 243 Korean subjects with major depressive disorder (MDD). The reduction in the Hamilton Depression score over the 8-week treatment period was not influenced by BDNF V66M genotypes. A marginal effect of genotype on somatic anxiety score was observed at baseline (P = 0.047 in the dominant model). However, genotype-time interaction had no effect on somatic anxiety score after the 8-week a treatment period. Plasma BDNF levels tended to increase during mirtazapine treatment, although without statistical significance (P = 0.055). After 8 weeks of mirtazapine treatment, plasma BDNF levels were higher in Met allele homozygotes (1499.7 ± 370.6 ng/mL) than in Val allele carriers (649.7 ± 158.5 ng/mL, P = 0.049). Our results do not support the hypothesis that the Val66Met promoter polymorphism in the BDNF gene influences the therapeutic response to mirtazapine in Korean MDD patients. However, our data indicate that this polymorphism results in increased plasma BDNF after mirtazapine treatment.

Abstract
We investigated the antibiotic concentration in fresh-frozen femoral head allografts harvested from two groups of living donors. Ten samples were collected from patients with osteoarthritis of the hip and ten from those with a fracture of the neck of the femur scheduled for primary arthroplasty. Cefazolin (1 g) was administered as a pre-operative prophylactic antibiotic. After storage at -80 degrees C for two weeks the pattern of release of cefazolin from morsellised femoral heads was evaluated by an in vitro broth elution assay using high-performance liquid chromatography. The bioactivity of the bone was further determined with an agar disc diffusion and standardised tube dilution bioassay. The results indicated that the fresh-frozen femoral heads contained cefazolin. The morsellised bone released cefazolin for up to four days. The concentration of cefazolin was significantly higher in the heads from patients with osteoarthritis of the hip than in those with a fracture.Also, in bioassays the bone showed inhibitory effects against bacteria.We concluded that allografts of morsellised bone from the femoral head harvested from patients undergoing arthroplasty of the hip contained cefazolin, which had been administered pre-operatively and they exhibited inhibitory effects against bacteria in vitro.

Abstract
Avian influenza virus (AIV) monitoring in migratory birds has been performed in Taiwan since 1998. From 1998 to 2007, 29,287 samples were collected from wild ducks, shorebirds, and other wild birds in the four wetlands around Taiwan and at two outside islets, Penghu and Kinmen. Virus isolation was performed for all collected samples by inoculating chicken embryos. The AIV in the allantoic fluid was identified using hemagglutination and reverse transcription PCR. The AIV prevalence from those samples was 0.81% (237/29,287). The peak prevalence reached 1.06% (186/17,493) from September to December, during which time migrating ducks came from the North. The prevalence from January to April was 0.51%. However, no virus was isolated from May to August. The partial HA genes of 28 H4 AIVs were sequenced and analyzed. The phylogenetic tree showed that a correlation existed between the isolation years and the evolutional distances. The pathogenicity of the isolated H5 and H7 AIVs was determined by intravenous pathogenicity index (IVPI) testing in specific-pathogen-free chickens and by HA cleavage sequencing. Using the IVPI test and the HA cleavage sequences, all of the H5 or H7 AIVs isolated were determined to be low pathogenicity AIVs.

Abstract
Dermal exposure to organophosphate pesticide is important because of its popular use. This study planned to compare the changes in serum acetylcholinesterase, paraoxonase and neuronal density of hippocampus and iso-cortex between two age groups of Swiss albino mice (18-day-old and 150-day-old) after dermal application of (1/2) LD50 of chlorpyrifos for 14 days. Statistically significant reduction was observed in serum acetylcholinesterase (Mann-Whitney test, p<0.05) and neuronal density (Independent samples t-test, p<0.05) in exposed groups compared to the control. The reduction in serum AChE and neuronal density was more pronounced in exposed adult mice than in exposed neonatal mice. The paraoxonase level was insignificant in control neonatal mice, whereas it was 890-fold more in exposed neonatal mice. Upregulated paraoxonase levels may be extrapolated to produce relatively lower reduction of cholinesterase and neuronal density in neonatal mice.

Abstract
Successful islet transplantation (ITx) is not only dependent on the number of islets, but also their quality, including viability, metabolic activity, and function. Islet quality decreases during cultivation after the isolation procedure. To overcome this obstacle, we established the practice of islet and mesenchymal stem cells (MSCs) coculture. This coculture condition improved the ATP (adenosine-5'-triphosphate)/ADP (adenosine-5'-diphosphate) ratio and insulin secretory function in vitro. It is believed that the enhancement of islet quality in islet-MSCs cocultures may be caused by the secretion of active agents by MSCs. Herein we have shown that interleukin-6 (IL-6), vascular endothelial growth factor-A (VEGF-A), hepatocyte growth factor (HGF), and transforming growth factor-beta (TGF-beta) were significantly increased as measured by enzyme-linked immunosorbent assay (ELISA) in MSCs-cultured medium, factors that have been shown to improve the survival, function, and angiogenesis/revascularization of islets. These results indicated that the quality of human islets was enhanced by trophic molecules secreted by MSCs, which influence the intracellular islet ATP content and insulin secretory function.

Abstract
Laser lithotripsy is an effective and safe method for difficult common bile duct (CBD) stones. However, radiolucent laser fibers make accurate fragmentation difficult and require continuous visual control or an accessory for effective targeting. The newly developed double-lumen basket may promote effective laser lithotripsy after stone capture. We performed laser lithotripsy using a double-lumen basket in 14 patients with CBD stones refractive to conventional endoscopic treatment, and evaluated the feasibility and efficacy of this procedure. Stones were successfully fragmented in 13 of 14 patients, and 13 patients eventually became stone-free. Mechanical lithotripsy was applied in two patients with biliary strictures. Minor complications were noted in three patients, including transient hemobilia in one patient. For a selected group of patients with difficult CBD stones, laser lithotripsy using a double-lumen basket appears to be an effective and safe method. However, continuous development of basket protocols to increase the success rate of lithotripsy is needed.

Abstract
Patients with systemic lupus erythematosus (SLE) frequently received corticosteroid therapy, resulting in osteonecrosis of the femoral head (ONFH). Prior studies demonstrated the effectiveness of extracorporeal shockwave treatment (ESWT) for ONFH.. This study evaluated the effectiveness of ESWT for ONFH in patients with SLE. We studied 39 patients, including 15 patients with SLE (26 hips) and 24 controls (29 hips). To each affected hip we applied ESWT (6000 impulses at 28 kV in a single session). Patients were ambulated with partial weight bearing for 4-6 weeks. The primary endpoint was the need for hip replacement. The secondary endpoints were improvement in hip pain and function and image changes on X-ray and MRI. Patients received total hip replacement in 12% of patients with SLE and in 14% of controls (P = 0.802). There was no statistically significant difference in pain scores (0.86 vs. 0.89; P = 0.467) and function scores (89% vs. 91%; P = 0.194) between patients with SLE and controls. SLE response to ESWT for ONFH is comparable with ONFH in patients without SLE.

Abstract
BACKGROUND Acupuncture is one of the most popular types of complementary/alternative medicine. It is sometimes used as a treatment for schizophrenia. AIMS The objective of this review is to assess systematically the clinical evidence for or against acupuncture as a treatment for schizophrenia. METHODS We searched 20 databases from their inception to May 2009 without language restrictions. All randomised clinical trials (RCTs) of acupuncture, with or without electrical stimulation or moxibustion for patients with schizophrenia were considered for inclusion. RESULTS Thirteen RCTs, all originating from China, met the inclusion criteria. One RCT reported significant effects of electroacupuncture (EA) plus drug therapy for improving auditory hallucunations and positive symptom compared with sham EA plus drug therapy. Four RCTs showed significant effects of acupuncture for response rate compared with antipsychotic drugs [n = 360, relative risk (RR): 1.18, 95% confidence interval (CI): 1.03-1.34, p = 0.01; heterogeneity: tau(2) = 0.00, chi(2) = 2.98, p = 0.39, I(2) = 0%]. Seven RCTs showed significant effects of acupuncture plus antipsychotic drug therapy for response rate compared with antipsychotic drug therapy (n = 457, RR: 1.15, 95% CI: 1.04-1.28, p = 0.008, heterogeneity: tau(2) = 0.00, chi(2) = 6.56, p = 0.36, I(2) = 9%). Two RCTs tested laser acupuncture against sham laser acupuncture. One RCT found beneficial effects of laser acupuncture on hallucination and the other RCT showed significant effects of laser acupuncture on response rate, Brief Psychiatric Rating Scale and clinical global index compared with sham laser. The methodological quality was generally poor and there was not a single high quality trial. CONCLUSION These results provide limited evidence for the effectiveness of acupuncture in treating the symptoms of schizophrenia. However, the total number of RCTs, the total sample size and the methodological quality were too low to draw firm conclusions. As all studies originated from China, international studies are needed to test whether there is any effect.

Abstract
Drug-eluting stents (DES) have been approved by the Food and Drug Administration for percutaneous coronary intervention (PCI) in the treatment of stable coronary disease but not in the treatment of acute myocardial infarction. In the past, treatment of acute myocardial infarction was mainly done via thrombolysis and balloon angioplasty. Although the rates of stroke, reocclusion, and revascularization were improved with the advent of bare-metal stents, rates of restenosis remained high. Primary PCI for ST-elevation myocardial infarction has also evolved to include the use of DES in this setting. However, this "off-label" use has not been without concerns regarding safety. Stent thrombosis contributes to major morbidity and mortality after PCI. Suggestions of higher rates of stent thrombosis with the use of DES as compared to bare-metal stents have raised questions about DES safety and efficacy. The aim of the authors was to provide an in-depth review of the safety of DES in acute myocardial infarction. They have therefore reviewed the most up-to-date data, including observational studies, randomized trials, and meta-analyses on the use of DES in ST-elevation myocardial infarction. Overall, DES appear to have a similar safety profile as compared to bare-metal stents in primary PCI in the treatment of ST-elevation myocardial infarction. Nevertheless, large-scale randomized studies are needed to further evaluate the safety profile of drug-eluting stents as compared to bare-metal stents in this setting.

Abstract
BACKGROUND Acupuncture is often used as a treatment for dementia and is claimed to be effective in improving intelligence. AIMS The objective of this review is to assess the clinical evidence for or against acupuncture as a treatment for Alzheimer's disease (AD). METHODS We searched the literature using 17 databases from their inception to August 2008, without language restrictions. We included all randomised clinical trials (RCTs) of needle acupuncture to treat human patients suffering from AD. Methodological quality was assessed using the Jadad score. RESULTS Three RCTs met all inclusion criteria. Two RCTs assessed the effectiveness of acupuncture on cognitive function compared with drug therapy. Their results suggested no significant effect in favour of acupuncture [n = 72, weight mean difference (WMDs), -0.55; 95% confidence intervals (CIs) -1.31 to 0.21, p = 0.15, heterogeneity: tau(2) = 0, chi(2) = 0.048, p = 0.49, I(2) = 0%]. Two RCTs tested acupuncture for activities of daily living (ADL). One RCT reported favourable effects of drug therapy compared with acupuncture for ADL, while the other failed to so. The meta-analysis of these data showed significant effects of drug therapy compared with acupuncture (n = 72, WMD, -1.29; 95% CIs: -1.77 to -0.80, p < 0.001, heterogeneity: tau(2) = 0, chi(2) = 0.17, p = 0.68, I(2) = 0%). CONCLUSION Even though the number of studies is small, the existing evidence does not demonstrate the effectiveness of acupuncture for AD.

Abstract
BACKGROUND AND STUDY AIMS The aim of this study in canines was to investigate the effectiveness and safety of self-expandable metal stents, which were coated with paclitaxel to minimize the tissue response. MATERIALS AND METHODS 14 dogs (5-10 kg) were randomly allocated to two groups. Drug-eluting stents (DES, n = 7) or nondrug-eluting stents (non-DES, n = 7) were endoscopically inserted and fixed in the esophagus of healthy dogs. Every 2 weeks, for a maximum period of 8 weeks, an endoscopic examination was performed to evaluate the status of stent insertion, the grade of tissue hyperplasia, and mucosal change at both ends of the stent. RESULTS One case of stent migration was observed after 4 weeks in the non-DES group. In this group, tissue reaction and hyperplasia remained for more than 4 weeks after stent insertion. By contrast, an endoscopic examination of the surrounding esophageal mucosa in the DES group showed very little tissue reaction, and the stent was easily separated from the esophageal tissue. CONCLUSION Although further studies are required to confirm our results, we suggest that these newly designed DES may provide an alternative tool to manage refractory benign esophageal stricture.

Abstract
Since outbreaks of highly pathogenic avian influenza (HPAI) in both human and poultry from 2003, it is critical to have effective vaccines. A cDNA fragment coding the entire hemagglutinin (HA) gene derived from an H5N1 strain (A/duck/China/E319-2/03) was cloned and expressed using the baculovirus system. Two weeks after receiving two doses of recombinant HA (rHA) vaccines, chickens develop high antibody response for hemagglutination inhibition (HI) at titer 7.2 log(2). Challenge studies revealed that vaccinated chickens with HI titers greater than 3 log(2) could have immunoprotection against the same HPAI H5N1 strain virus challenge through intranasal route. Additionally, HI titer of 5 log(2) determined whether the live viruses could not be detected from oropharyngeal, cloacal discharge or in tissues. This result suggests that the rHA expressed from baculovirus system could be a candidate for the development of a safe and efficient subunit vaccine for HPAI (H5N1).
