Abstract
OBJECTIVE To investigate the long-term therapeutic effect of autologous hematopoietic stem cell transplantation in patients with End-stage Liver Disease (ESLD). PATIENTS AND METHODS Forty-eight ESLD patients underwent autologous CD34+ stem cell transplantation were retrospectively reviewed. Changes in clinical and biochemical data, complications, and quality of life were monitored at 3, 6, 12, 36, and 60 months following the stem cell transplantation. Liver biopsies were obtained for histopathological analysis using Ishak system. RESULTS Marked improvement in clinical and biochemical data was observed during the long-term follow-up. Serum albumin was significantly increased (p<0.001), while total serum bilirubin, prothrombin time (PT), and international normalized ratio (INR) were all significantly decreased (p<0.001). Ishak inflammation and fibrosis scores were significantly decreased with the increased time (p<0.001). The number of patients with ascites, model of end-stage liver disease (MELD) score, Child-Pugh class, and indocyanine green (ICG) score were all markedly reduced with increased time. Meanwhile, the quality of life score of the patients was significantly increased (p<0.001). Six patients died during the 5-years follow-up, and complications occurred in 17 patients. The incidence of complications was significantly associated with mortality of the patients (p<0.05). CONCLUSIONS The study provided the evidence that autologous CD34+ stem cell transplantation could offer a long-term therapeutic benefit to patients with ESLD. The complications occurred during the process was significantly associated with survival of the patients. Future studies on a large cohort of patients are needed to confirm the long-term effect of stem cell therapy on ESLD.

Abstract
The association of intracranial aneurysm and hemangioblastoma is extremely rare. This report regards a patient affected by Von Hippel-Lindau syndrome with multiple hemangioblastoma and two intracranial aneurysms, of which one was on a hemangioblastoma feeder vessel and the other on an unrelated vessel. Review of the literature revealed 13 other previously reported cases. Possible mechanisms to explain the association are discussed.

Abstract
We experimentally report the observation of dispersive shock waves from a short pulse superimposed onto a small continuous wave background in optical fibers. We show that the background allows us to strongly enhance the extension and contrast of the oscillatory wave train inherent to the dispersive shock. More than seven periods of oscillations with high contrast are observed experimentally and confirmed with numerical simulations. The dynamics of the process are simply explained from spectro-temporal representations.

Abstract
BACKGROUND Recessive dystrophic epidermolysis bullosa (RDEB) is a rare heritable blistering skin condition caused by loss-of-function mutations in the COL7A1 gene. Incongruent gene transmission is occasionally reported in recessive diseases, and its underlying mechanism is often uniparental disomy (UPD). AIM To understand the genetic basis of incongruent gene transmission in a Chinese family with RDEB, in which a discrepancy of COL7A1 genotyping was encountered during our mutation analysis. METHODS We used a pCAS2 minigene-based in vitro splicing assay to confirm the pathogenicity of the splicing variant we identified in the proband. Next, a combination of genetic tools, including whole-genome SNP array analysis and multiplex ligation-dependent probe amplification copy number analysis, was used to unravel the cause of the discrepancy in the COL7A1 genotyping. RESULTS Sanger sequencing identified a novel, single-peak mutation, c.4980+5G>C, in COL7A1 in the proband, which was heterozygous in his father and wild type in his mother. In vitro splicing assay showed that c.4980+5G>C was pathogenic and led to skipping of COL7A1 exon 53. SNP array analysis and multiplex ligation-dependent probe amplification of the proband's DNA revealed a maternally derived, de novo, interstitial deletion on chromosome 3p21.31, which removed COL7A1 and 15 flanking genes, excluding the possibility of UPD. CONCLUSION Our findings favour an exceptionally rare event, namely a de novo COL7A1 microdeletion in concurrence with an inherited mutation in trans. This study should aid molecular diagnosis and genetic counselling of RDEB and possibly other recessive diseases in which genotyping discrepancy is encountered.

Abstract
OBJECTIVE To investigate the clinical application of scalp skin grafts in reconstruction of external auditory meatus in congenital aural atresia. METHODS We conducted a retrospective study on 85 patients of congenital aural atresia, all of whom were unilateral, operated from March of 2008 to December of 2010 in ENT department of the Sun Yat-Sen Memorial Hospital. The patients enrolled in the study were between 6 to 37 years old (median age 12 years), 55 male and 30 female. Scalp surface graft in ipsilateral temporal region was harvested to cover the bony external auditory meatus. RESULTS All of these scalp split-thickness skin grafts survived without necrosis, no restenosis was found in these external auditory meatus. Neither scar nor alopecia was found in the skin-harvesting region, and hairs grew well. Granulations occurred in 27 cases in the first to sixth month posteroperatively, 20 cases recovered after local treatment. In the first year, 30 cases obtained hearing improvement more than 15 dB, 36 cases gained more than 25 dB and 19 cases gained more than 35 dB. Totally 8 patients were lost in the 4 to 5 years of follow-up, 70 cases (70/77, 90.9%) developed new external auditory meatus, 7 cases (7/77, 9.1%) suffered from stenosis in different degrees, but no atresia was found in these patients. CONCLUSION Scalp split-thickness skin grafts has significant clinical advantage in meatoplasty of congenital aural atresia.

Abstract
We present evidence that high temperature CVD growth of SWNTs under conditions of continuous spinning of macroscopic fibers leads to an inherent predominance of high chiral angle CNTs, peaking at the armchair end. Raman, UV-vis-NIR absorption, and photoluminescence spectroscopy measurements show the prevalence of metallic SWNTs. The complete chiral angle distribution is obtained by electron diffraction of over 390 CNTs. It is biased towards high chiral angles and peaks at the armchair end (30°), in good agreement with the established atomistic models for SWNT growth from a liquid catalyst. Based on the Fe-C-S constituent binary and ternary phase diagrams, thermodynamic calculations of phase compositions from fast cooling and experimental evidence of a post-synthesis catalyst, the proposed thermodynamic path of the catalyst is to form a solid FCC Fe core and a liquid Fe-S shell. S in the outer liquid shell first stabilizes the edge of the nascent CNT, but once a graphitic wall forms it is rejected due to the high interfacial energy of the Fe-C-S alloy.

Abstract
Cucurbitacin-I (Cu-I, also known as Elatericin B or JSI-124) is developed to inhibit constitutive and abnormal activation of STAT3 in many cancers, demonstrating a potent anticancer activity by targeting disruption of STAT3 function. Here, we for the first time systematically studied the underlying molecular mechanisms of Cu-I-induced gastric cancer cell death both in vitro and in vivo. In our study, we show that Cu-I markedly inhibits gastric cancer cell growth by inducing G2/M phase cell cycle arrest and apoptosis at low nanomolar concentrations via a STAT3-independent mechanism. Notably, Cu-I significantly decreases intracellular GSH/GSSG ratio by inhibiting NRF2 pathway to break cellular redox homeostasis, and subsequently induces the expression of GADD45α in a p53-independent manner, and activates JNK/p38 MAPK signaling. Interestingly, Cu-I-induced GADD45α and JNK/p38 MAPK signaling form a positive feedback loop and can be reciprocally regulated by each other. Therefore, the present study provides new insights into the mechanisms of antitumor effects of Cu-I, supporting Cu-I as an attractive therapeutic drug in gastric cancer by modulating the redox balance.

Abstract
OBJECTIVES There is an urgent need to develop interventions and policies to mitigate the health effects of obesity by targeting its metabolic mediators. Adrenomedullin 2 (AM2)/intermedin (IMD) is a secreted peptide that has an important role in protecting the cardiovascular system. However, the role of AM2 in type 2 diabetes is unknown. METHODS Wild-type (WT) and aP2/AM2 transgenic (aAM2-tg) mice were fed a high-fat diet (HFD) for 8 weeks, and WT mice were treated with AM2 through mini-osmotic pumps. Indirect calorimetry, ambulatory activity and food intake, hyperinsulinemic-euglycemic clamp test, glucose and insulin tolerance tests were used for assessing insulin resistance. Rat primary adipocytes and pre-adipocyte-derived adipocytes were used for in vitro experiments. Real-time PCR and western blot were used for analyses of gene expression and protein level. RESULTS AM2 and receptor activity-modifying proteins expressions were significantly decreased in the adipose tissue of obese mice. AM2 treatment significantly reduced blood glucose, fasting serum insulin and free fatty acid levels, improved glucose tolerance and insulin sensitivity, and increased the glucose infusion rate during a hyperinsulinemic-euglycemic clamp test, indicating ameliorated HFD-induced insulin resistance. These effects were consistently observed in aAM2-tg mice under HFD conditions, whereas the aAM2-tg mice showed less weight gain and improved glucose tolerance and insulin sensitivity. More importantly, the aAM2-tg mice had increased oxygen consumption and CO2 production, reflecting more energy expenditure. These effects may be due to increased AMP-activated protein kinase phosphorylation and reduced peroxisome proliferator-activated receptor gamma co-activator 1α (PGC1α) acetylation, which result in interactions between PGC1α and PR domain containing 16 and then promote uncoupling protein 1 (UCP1) expression in adipocytes. CONCLUSIONS These results indicate that endogenous AM2 might be involved in energy metabolism in adipocytes through the upregulation of UCP1 expression.

Abstract
BACKGROUND The impact of potentially pathogenic micro-organisms (PPMs) on Chinese patients with steady-state bronchiectasis is unknown. METHODS Peripheral blood and sputum were sampled to determine inflammatory markers and sputum bacterial density. Spirometry and diffusing capacity were measured. Quality of life was assessed using the St George's Respiratory Questionnaire. RESULTS Of 144 patients with steady-state bronchiectasis, Pseudomonas aeruginosa was isolated in 44 cases (30.6%). Compared with other PPMs, P. aeruginosa had a more pronounced influence on airway inflammation and spirometry, but not on systemic inflammation or quality of life. The impact of PPMs other than P. aeruginosa on clinical indices was similar. Bacterial density was not correlated with most clinical parameters. Factors associated with PPM isolation included bronchiectasis symptoms for ⩾ 10 years (OR 2.13) and ⩾ 4 bronchiectatic lobes (OR 2.82). Having ⩾ 4 exacerbations within 2 years (OR 2.18) and cystic bronchiectasis (OR 2.23) was associated with the colonisation of PPMs, i.e., isolating an identical PPM on at least two occasions within 1 year. CONCLUSION In patients with steady-state bronchiectasis in Guangzhou, P. aeruginosa is the most common organism causing heightened airway inflammation and poor lung function. PPM isolation or colonisation should be suspected in case of longer duration of symptoms, multilobar bronchiectasis, frequent exacerbation and cystic bronchiectasis.

Abstract
OBJECTIVE The aim of this study was to estimate MS prevalence according to three criteria and its risk factors among men in rural China. DESIGN Cross-sectional study. SETTING The Nantong Metabolic Syndrome Study (NMSS) was conducted during 2007-2008 in Nantong, China. PARTICIPANTS 6997 male participants aged 18-74 years. MEASUREMENTS In person interviews, blood glucose and lipid measurements were accomplished. RESULTS The prevalence of MS was 12.86%, 8.55% and 15.28% according to IDF, ATPIII and ATPIII-modified criteria, respectively. The IDF and ATP III-modified criteria agreed only moderately with ATP III criteria (κ= 0.56 and 0.68), whereas ATP III-modified and the IDF criteria agreed perfectly (κ= 0.90). Vigorous occupational physical activity was associated with a low prevalence of MS with Odds ratio (OR) of 0.58 (95% confidence interval (CI): 0.45-0.74). Beer drinkers (alcohol ≤ 6.2 g/day) and rice wine drinkers (alcohol ≤ 9.0 g/day) had about 34% and 33% low risks of developing MS respectively, compared with non-drinkers. OR of MS was 1.95 (95% CI: 1.39-2.73) in men who had familial history of at least two diseases, including hypertension and diabetes, compared with men without familial history of those diseases. CONCLUSIONS Our data suggested that MS is highly prevalent among men in rural China. Family history of diabetes and hypertension is a risk factor in MS development. Physical activity, rice wine and beer consumption are associated with a significantly lower risk.

Abstract
UNLABELLED This population-based cross-sectional study in an older Chinese population shows a link between sleep duration, sleep timing, and osteoporosis risk, suggesting that sleep may have a role in osteoporosis development. These findings may help to identify contributing mechanisms and provide new opportunities for sleep-focused interventions to prevent osteoporosis. INTRODUCTION Accumulated evidence suggests that sleep pattern disruption may lead to alterations in physiology, potentially triggering the development of osteoporosis. The present study sought to examine whether sleep duration or sleep timing is associated with osteoporosis. METHODS A total of 31,769 participants (aged 45-86 years) were recruited from the Dongfeng-Tongji cohort study. All participants completed questionnaires and medical examinations and provided blood samples. The presence of osteoporosis was determined using calcaneal quantitative ultrasonography. Logistic regression models were used to evaluate the association of sleep duration and timing with osteoporosis, after adjusting for potential confounders. RESULTS The prevalence of osteoporosis was 14.2 % in men and 23.9 % in women. After controlling for potential confounders, the adjusted odds ratio (OR) [95 % confidence interval (CI)] for osteoporosis comparing sleep duration of 9 h or longer with the reference (7-8 h) was 1.40 (1.22-1.62) in men and 1.20 (1.07-1.33) in women. Men with early sleep timing (going to sleep before 21:00 h) were more likely to have osteoporosis (OR, 1.43; 95 % CI, 1.16-1.78) than those with normal sleep timing (going to sleep between 21:00 and 23:00 h). In the interaction analysis, participants with long sleep duration and early sleep timing had the highest risk of osteoporosis both in men (OR, 1.79; 95 % CI, 1.48-2.16) and women (OR, 1.41; 95 % CI, 1.19-1.66). CONCLUSIONS Long sleep duration (≥9 h) and early sleep timing were independently and interactively associated with an increased risk of osteoporosis in this older Chinese population.

Abstract
BACKGROUND The Leicester Cough Questionnaire (LCQ) has been validated for assessing cough-specific health status in bronchiectasis. We translated the LCQ into Mandarin Chinese and investigated its validity, reliability and responsiveness. METHODS The LCQ was translated into Mandarin Chinese using the forward-backward translation procedure. A total of 144 out-patients completed the Mandarin Chinese version of the LCQ (LCQ-MC), the Hospital Anxiety and Depression Scale (HADS) and the St George's Respiratory Questionnaire. Reassessments were performed during exacerbations and at 6 months. Concurrent validation, internal consistency, repeatability and responsiveness were determined. RESULTS Minor cultural adaptations were made to the wording of LCQ-MC. No other difficulties were found during the translation process, with all items easily adapted to acceptable Mandarin Chinese. The questionnaire was not changed in terms of content layout and the order of the questions. In cognitive debriefing interviews, participants reported that the questionnaire was acceptable, relevant, comprehensive and easy to complete. The LCQ-MC showed good concurrent validity, internal consistency and test-retest reliability. Responsiveness was shown by significant changes in LCQ-MC scores between steady state, the first exacerbation and following 2-week antibiotic treatment (both interval changes, P < 0.01) CONCLUSION: The LCQ-MC is a valid, reliable and responsive instrument for determining cough-specific health status in Chinese bronchiectasis patients.

Abstract
Marie Unna hereditary hypotrichosis (MUHH) is a rare autosomal dominant genodermatosis characterized by coarse, wiry, twisted hair developing during early childhood, with subsequent progressive hair loss. Recently, mutations in U2HR, an inhibitory upstream open reading frame in the 5' untranslated region of the human hairless gene (HR), were identified as the underlying cause of MUHH. We investigated two unrelated Chinese multigenerational families with MUHH. By sequencing U2HR in the two families, we identified two previously reported mutations, c.1A >T (p.Met1?) and c.104A>G (p*35Wext1263*). Both these mutations cosegregated with the disease phenotype in the two families.
