Abstract
Bighead carp (Aristichthys nobilis) is an important aquaculture fish worldwide. Genetic linkage maps for the species were previously reported, but map resolution remained to be improved. In this study, a second-generation genetic linkage map was constructed for bighead carp through a pseudo-testcross strategy using interspecific hybrids between bighead carp and silver carp. Of the 754 microsatellites genotyped in two interspecific mapping families (with 77 progenies for each family), 659 markers were assigned to 24 linkage groups, which were equal to the chromosome numbers of the haploid genome. The consensus map spanned 1917.3 cM covering 92.8% of the estimated bighead carp genome with an average marker interval of 2.9 cM. The length of linkage groups ranged from 52.2 to 133.5 cM with an average of 79.9 cM. The number of markers per linkage group varied from 11 to 55 with an average of 27.5 per linkage group. Normality tests on interval distances of the map showed a non-normal marker distribution; however, significant correlation was found between the length of linkage group and the number of markers below the 0.01 significance level (two-tailed). The length of the female map was 1.12 times that of the male map, and the average recombination ratio of female to male was 1.10:1. Visual inspection showed that distorted markers gathered in some linkage groups and in certain regions of the male and female maps. This well-defined genetic linkage map will provide a basic framework for further genome mapping of quantitative traits, comparative mapping and marker-assisted breeding in bighead carp.

Abstract
This paper presents a microfluidic device enabling culture of vascular smooth muscle cells (VSMCs) where extracellular matrix coating, VSMC seeding, culture, and immunostaining are demonstrated in a tubing-free manner. By optimizing droplet volume differences between inlets and outlets of micro channels, VSMCs were evenly seeded into microfluidic devices. Furthermore, the effects of extracellular matrix (e.g., collagen, poly-l-Lysine (PLL), and fibronectin) on VSMC proliferation and phenotype expression were explored. As a platform technology, this microfluidic device may function as a new VSMC culture model enabling VSMC studies.

Abstract
BACKGROUND The aim of this study is to determine whether PAQR3, a protein specifically localized in the Golgi apparatus, is associated with tumor progression, metastasis and survival of human patients with gastric cancer. PATIENTS AND METHODS PAQR3 expression status was investigated in a large panel of gastric cancer (n = 300) and their corresponding para-cancerous histological normal tissues (PCHNT) at both mRNA and protein levels. The correlation of PAQR3 expression levels with clinical features such as metastasis and prognosis was analyzed. The effect of PAQR3 on the growth and migration of gastric cancer cells was also determined. RESULTS PAQR3 was frequently down-regulated in gastric cancer samples compared with PCHNT at both mRNA and protein levels (both P < 0.0001). The expression level of PAQR3 was negatively correlated with Helicobacter pylori infection (P < 0.0001), tumor size (P < 0.0001), tumor stage (P < 0.0001), venous and lymphatic invasion (P < 0.0001), distant and nodal metastasis (P < 0.0001), and patient survival (P < 0.0001). Down-regulation of PAQR3 was highly correlated with increased epithelial-mesenchymal transition (EMT) in gastric cancer samples. In addition, PAQR3 overexpression was able to negatively modulate cell proliferation, migration and EMT of gastric cancer cells. CONCLUSION PAQR3 is markedly down-regulated in human gastric cancers. PAQR3 expression level is closely associated with the progression and metastasis of gastric cancers. PAQR3 is also a new genetic signature that can predict the prognosis of the patients with gastric cancer.

Abstract
BACKGROUND Use of TIPSS is associated with increases in ammonia concentration and hepatic encephalopathy (HE) risk. L-ornithine-L-aspartate (LOLA) is effective in reducing ammonia concentration. AIM To evaluate the effects of LOLA on venous ammonia concentration after TIPSS. METHODS The included patients were randomised to receive LOLA or no-LOLA treatment for 7 days. Fasting and post-prandial venous ammonia levels were the primary outcomes. Psychometric performance, post-TIPSS HE, and liver and renal function were assessed as secondary outcomes. RESULTS Of 133 cirrhotic patients who received successful TIPSS between November 2011 and June 2012, 40 met the inclusion criteria and were randomised to the LOLA (n = 21) or control (n = 19) groups. Change in fasting ammonia significantly favoured the LOLA group at days 4 (P = 0.001) and 7 (P = 0.003). Changes in post-prandial ammonia concentration significantly favoured the LOLA group at days 1, 4 and 7 as well. During the study period, patients in the LOLA group had better improvement in psychometric tests than those in the control group. Overt HE during treatment was observed in one patient in the LOLA group and three patients in the control group (P = 0.331). There were no differences in complications, adverse events or mortality between the two groups. CONCLUSIONS Prophylactic use of LOLA infusion after TIPSS is safe and effective in significantly reducing the increase of venous ammonia concentration, and can benefit the patient's mental status as well.

Abstract
We retrospectively reviewed the outcomes of 33 consecutive patients who had undergone an extra-articular, total or partial scapulectomy for a malignant tumour of the shoulder girdle between 1 July 2001 and 30 September 2013. Of these, 26 had tumours which originated in the scapula or the adjacent soft tissue and underwent a classic Tikhoff-Linberg procedure, while seven with tumours arising from the proximal humerus were treated with a modified Tikhoff-Linberg operation. We used a Ligament Advanced Reinforcement System for soft-tissue reconstruction in nine patients, but not in the other 24. The mean Musculoskeletal Tumor Society score (MSTS) was 17.6 (95% confidence interval (CI) 15.9 to 19.4); 17.6 (95% CI 15.5 to 19.6) after the classic Tikhoff-Linberg procedure and 18.1 (95% CI 13.8 to 22.3) after the modified Tikhoff-Linberg procedure. Patients who had undergone a LARS soft-tissue reconstruction had a mean score of 18.6 (95% (CI) 13.9 to 22.4) compared with 17.2 (95% CI 15.5 to 19.0) for those who did not. The Tikhoff-Linberg procedure is a useful method for wide resection of a malignant tumour of the shoulder girdle which helps to preserve hand and elbow function. The method of soft-tissue reconstruction has no effect on functional outcome.

Abstract
AIM Studies have shown that the incidence and development of pathological changes in the walls of the great saphenous vein and splenic vein are closely related to high venous pressure. Such changes are referred to as "vascular adaptive remodeling responses under high venous pressure". The proposition of the concept of vascular remodeling contributes to our knowledge of pathological changes in the venous wall (dilation of the venous lumen and thickening of the venous wall). In the present study, we compared the histomorphology and cytomorphology of the walls of varicose great saphenous veins (GSVs) and diseased splenic veins (SVs) to investigate the remodeling of the venous wall under high hemodynamic pressure. METHODS We collected 34 samples of varicose great saphenous veins and diseased splenic veins. Thirty-four samples of normal great saphenous veins and splenic veins were also collected (control group). Samples were made into slices and observed under light microscopy and electron microscopy. The thickness of the tunica intima and tunica media as well as the inner diameter of the venous lumen were measured. RESULTS Under light microscopy, the walls of varicose veins stained with H&E were unevenly thickened, and those of diseased splenic veins were evenly thickened; mucoid degeneration of the tunica intima of varicose veins was not obvious by Masson staining (2/20 cases). The boundary between the tunica intima and tunica media was clearly defined. Uneven hyperplasia of muscular connective tissues was observed. For the diseased splenic-vein group, mucoid degeneration of the tunica intima was obvious (8/14 cases), with an unclearly defined boundary between the tunica intima and tunica extima. Uneven hyperplasia of muscular connective tissues was also observed. Differences in the thickness and inner diameter of the tunica intima and tunica media between the great saphenous vein and the splenic vein were significantly different. Under electron microscopy, mitochondrial degeneration in endothelial cells was observed in both groups. Increased numbers of rough endoplasmic reticula in the cytoplasm of smooth muscle cells, ribosomes and mitochondria and decreased numbers of myofilaments were also observed. CONCLUSION High hemodynamics affected the remodeling of varicose great saphenous veins and diseased splenic veins. The histomorphology of visceral veins showed more significant pathological changes than that of peripheral veins. Similar cytomorphological changes were observed in both groups.

Abstract
TPD52L2 (tumor protein D52-like 2) is a member of TPD52 family which has been implicated in multiple human cancers. Recently, TPD52 protein was shown to be associated with several malignancies, but very little is known about the function of TPD52L2 in cancers, especially in glioma to date, and its roles in glioma occurrence and progression remain to be elucidated. In the present study, we employed lentivirus-mediated RNA interference (RNAi) to knock down TPD52L2 expression in human glioma cell line U251. We found that knockdown of TPD52L2 significantly not only inhibited cell proliferation and colony formation, but also induced G0/G1 cell cycle arrest in vitro. Taken together, these findings suggest that TPD52L2 might play an important role in glioma tumorigenesis.

Abstract
We report our early experience with the use of a new prosthesis, the Modular Hemipelvic Prosthesis II, for reconstruction of the hemipelvis after resection of a primary malignant peri-acetabular tumour involving the sacroiliac joint. We retrospectively reviewed the outcome of 17 patients who had undergone resection of a pelvic tumour and reconstruction with this prosthesis between July 2002 and July 2010. One patient had a type I+II+III+IV resection (ilium + peri-acetabulum + pubis/ischium + sacrum) and 16 had a type I+II+IV resection (ilium + acetabulum + sacrum). The outcome was assessed at a mean follow-up of 33 months (15 to 59). One patient was alive with disease, 11 were alive without disease and five had died of disease. The overall five-year survival rate was 62.4%. Six patients had a local recurrence. The mean Musculoskeletal Tumour Society score was 58% (33 to 77). Deep infection occurred in two patients, problems with wound healing in five and dislocation in one. For patients with a primary malignant peri-acetabular sarcoma involving the sacroiliac joint, we believe that this new prosthesis is a viable option for reconstruction of the bony defect left following resection of the tumour. It results in a satisfactory functional outcome with an acceptable rate of complications. Cite this article: Bone Joint J 2014;96-B:399–405.

Abstract
Background: Preoperative alpha-L-fucosidase (AFU) has been used as a diagnostic biomarker for hepatocellular carcinoma (HCC), but its role as a prognostic predictor after partial hepatectomy has not been well defined. The study aimed to investigate the prognostic significance of preoperative serum AFU for HCC patients after hepatic resection. Methods: A retrospective training data set and a prospective validation data set were used to evaluate the prognosis of HCC after partial hepatectomy. A total of 669 patients with histopathologically confirmed HCC were enrolled. Univariate and multivariate analyses were used to identify the prognostic significance of preoperative serum AFU. Results: The retrospective training data set showed a preoperative AFU>35 u l−1 should be used. The prospective validation data set showed preoperative AFU was an independent prognostic factor of overall survival (OS) (P=0.008; hazard ratio: 2.333; 95% confidence interval: 1.249–4.369). Patients with a preoperative AFU>35 u l−1 had a lower recurrence-free survival rate and an OS rate than those with AFU⩽35 u l−1, and they have a higher tendency to form macrovascular invasion. Furthermore, the prognostic significance of AFU>35 u l−1 could also be applied to patients with alpha-fetoprotein levels of ⩽400 ng ml−1. Conclusions: Preoperative serum AFU is a prognostic predictor of HCC.

Abstract
OBJECTIVE The aim of this study was to observe the effects of stellate ganglion block (SGB) on hemodynamic changes and intrapulmonary shunt during one-lung ventilation (OLV). PATIENTS AND METHODS Thirty ASA class I-II patients undergoing elective esophageal surgery were randomly divided into two groups: general anesthesia group (group N, n=15) and general anesthesia combined SGB group (group S, n=15), patients in group S were received left SGB before induction. Radial artery was cannulated for arterial blood pressure (ABP) monitoring and blood sampling and Swan-Ganz catheter was position in the pulmonary artery via right internal jugular vein under local anesthesia. ECG, MAP, HR, CVP, continuous cardiac output (CCO) index and BIS were continuously monitored during anesthesia. General anesthesia was induced with propofol 1.5-2.0 mg/kg, sufentanil 0.4 μg/kg, and Rocuronium 0.6-0.9 mg/kg. Endobronchial occluder was placed blindly after tracheal indubation and the correct position was verified by auscultation and fiberoptic bronchoscopy. The patients were mechanically ventilated. The ventilation conditions were Fio2=100%, VT = 8-10 ml/kg, I: E = 1:2 and respiratory rate was adjusted to maintained PETCO2 at 35-45 mmHg during both two-lung ventilation (TLV) and OLV. Anesthesia was maintained with continuous infusion of propofol 4-10 mg/kg·h, sufentanil 0.2 μg/kg·h, vecuronium o.1 mg/kg·h, BIS was maintained at 45-55. Blood samples were taken from radial artery and S-G catheter for blood gas analysis at following intervals: during spontaneous breathing when the patient was awake (T0), 1 min after tracheal indubation (T1), 1 min after patient was placed in lateral position (T2) and 15 min after it (T3), 1 min after ribs was braced (T4), 30, 60, 120 min during the course of OLV (T5, T6, T7), the two lungs were ventilated again for 30 min (T8) and Qs/Qt was calculated. RESULTS SVRI, MAP, HR in group N increased significantly at T1, T2, T4 compared with group S (p < 0.05). Qs/Qt was significantly increased after patient was placed in lateral position and increased further during OLV; the calculated Qs/Qt values were highest at T5· PaO2 was significantly lower after OLV was started and reached the lowest level at T6 then was gradually increasing. There was no significant difference in Qs/Qt and PaO2 at all time points between two groups. CONCLUSIONS SGB before induction effectively suppress the stress response work as stable blood dynamics and does not affect Qs/Qt and arterial oxygenation during OLV, SGB is a safe technique of anesthesia for general thoracic surgery.

Abstract
AIM The purpose of this study was to investigate the proliferation of vasa vasorum (VV) in the walls of thrombophlebitic saphenous vein (TSV), and to evaluate the influence of high venous pressure and lack of oxygen on the VV. METHODS The specimens of the great saphenous vein were collected: 11 primary varicose vein (PVV), 11 TSV and, as a control, eight normal great saphenous vein. Masson staining and immunohistochemistry for CD34 were used to observe the status of VV, and the number of VV were counted under light microscopy. RESULTS VV of the thrombophlebitic saphenous vein group (TSVG) were clustered together in adventitia, increased linearly in media, and scattered appearance in intima, were increased partially in intima of thrombus rupturing. In TSVG, the number of VV observed in adventitia, media and intima was 16.738±7.685, 4.845±2.537, 2.448±3.030, respectively. In the primary varicose vein group (PVVG), the corresponding values were 14.280±4.440, 2.965±1.125, 0.500±0.548. And the number was 8.911±2.629, 0.150±0.424, 0±0 in the control group (CG). Significantly higher numbers of VV were observed in the TSVG as compared to the PVVG or CG (P<0.05). No significant difference was observed between intima and media (P>0.05). CONCLUSION Thrombi in varicose veins can induce proliferation of VV, which may be involved in high venous pressure and hypoxia.

Abstract
Central nervous system neurons fail to regenerate after birth, which greatly hampers the effective treatment of many neurodegenerative diseases. Neurons differentiated from induced pluripotent stem cells have been considered a possible option for cell-based therapies. Recent discoveries have revealed that fibroblasts can be directly converted into neurons without a transition through a pluripotent state. This approach might serve as a more efficient and convenient method for the cellular therapy of neurodegenerative diseases. Currently, several types of neurons have been directly generated from fibroblasts, including dopamine neurons, motor neurons and neural progenitor cells. In our study, by screening a series of candidate genes, we found that the adenovirus-mediated transduction of Ascl1, Brn3b and Ngn2 can directly convert mouse fibroblasts to retinal ganglion-like cells. The induced retinal ganglion-like cells co-express multiple retinal ganglion cell markers, and exhibit membrane properties of functional neurons. The reprogramming mediated by adenoviruses occurs much sooner than that mediated by lentiviruses. Furthermore, the induced retinal ganglion-like cells that are produced via adenoviral gene delivery are free of exogenous gene integration. Retinal ganglion-like cells that are induced by adenoviruses demonstrate great potential applicability in clinical therapy and provide a novel platform for the research of retinal degenerative diseases.

Abstract
BACKGROUND Lung cancer is the most common cause of cancer-related death worldwide. Recently, deep transcriptional sequencing has been used as an effective genomic assay to get an insight into this disease. AIM This study is carried out to identify specific regulatory elements (SREs) in lung cancer. MATERIALS AND METHODS The RNA-sequencing data on lung cancer sample and normal sample were downloaded from NCBI. TopHat and Cufflinks were used to analyze differential alternative splicing in lung cancer by using RNA-sequencing data. Further, we searched specific SREs in lung cancer through finding over-represented hexamers around high expression exons. RESULTS According to the Jensen-Shannon divergence between two samples and the p-value of t-test, we found 53 genes with differential alternative splicing in lung cancer. In the analysis of SREs, we found 763 specific SREs between lung cancer sample and normal sample. CONCLUSIONS These results may give an insight into how alternative splicing causes differential expression in lung cancer.

Abstract
To evaluate the bioequivalence of a new formulation of atomoxetine hydrochloride (CAS 82248-59-7) capsules (test) and an available branded capsules (reference) after administration of a single 40 mg dose, randomized, open-label, 2-period crossover study was conducted in 22 healthy male Chinese subjects with a 1-week wash-out period. This study was designed for/the Honglin Pharmaceutical Co. Ltd and contracted to be done by the Beijing Anding Hospital in order to satisfy Chinese regulatory requirements to allow marketing of this generic product and performed according to the criteria of SFDA. Blood samples were collected before and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 12, 16 and 24 h after drug administration. Plasma concentrations were determined by high-performance liquid chromatography (HPLC) with UV detection. A non-compartmental method was used to calculate the pharmacokinetic parameters and evaluate bioequivalence of the 2 formulations. The 90% confidence interval (CI) of the ratios (test/reference) of atomoxetine for AUC0-24, AUC0-∞ and Cmax were 100.9% (93.6-108.8%), 103.1% (95.1-111.7%) and 105.2% (92.8-119.4%), respectively, which fell within the interval of 80-125% and 75-133%. No clinically significant changes or abnormalities were noted in laboratory data and vital signs. From these results it can be concluded that the test formulation of atomoxetine capsules met the regulatory criterion for bioequivalence to the reference formulation.

Abstract
The efficacy of entomopathogenic nematodes (EPNs) against the white grub Holotrichia parallela Motschulsky (Coleoptera: Scarabaeidae) in the peanut (Arachis hypogaea L.) fields was evaluated. In the first experiment with a high initial white grub population (24.65 +/- 2.44 larvae per m2) in the field, Steinernema longicaudum X-7 and Heterorhabditis bacteriophora H06 at 10,000 and 5,000 infective juveniles (IJs) per plant contributed to significantly higher percentage reduction of the white grub larvae, lower percentage of the injured legume, and higher peanut yield compared with chlorpyrifos and other treatments. The peanut yields harvested from the plots treated with EPNs at 5,000 IJs per plant were at least 70% higher than that from the untreated control (water) and at least 30% higher than that from chlorpyrifos-treated plots. In the second experiment with a low initial white grub population (8.07 +/- 1.29 larvae per m2) in the field, EPN treatment did not increase peanut yield compared with the other treatments. But both S. longicaudum X-7 and H. bacteriophora H06 gained higher percentage reduction of the white grub larvae and lower percentage of the injured legume than Steinernema carpocapsae (Weiser) All and the control. The cost-benefit of using EPNs for white grub control was estimated to be comparable with that of using chemicals. S. longicaudum X-7 and H. bacteriophora H06 showed promise for white grub control in peanut fields.
