Abstract
BACKGROUND Excessive epithelial-to-mesenchymal transition (EMT) of nasal epithelial cells (NECs) play a prominent role in chronic rhinosinusitis with nasal polyps (CRSwNP) pathogenesis. Long intergenic non-coding RNA 01094 (LINC01094) was previously reported to be overexpressed in CRSwNP, while the regulatory mechanism by which LINC01094 regulates CRSwNP progression remains unclear. Our study aimed to investigate the role of LINC01094 in CRSwNP development. METHODS hNEC were isolated from tissues of controls and CRSwNP patients and stimulated with interleukin (IL)-13. 3-(4, 5-Dimethylthiazolyl2)-2, 5-diphenyltetrazolium bromide (MTT) assay was employed to analyze hNEC viability. Flow cytometry was employed to analyze pyroptosis. Immunofluorescence was employed to analyze Snail nuclear translocation. The interactions between LINC01094, fused in sarcoma (FUS) and high mobility group box-1 (HMGB1) were analyzed by RNA immunoprecipitation (RIP) and RNA pull-down assays. RESULTS LINC01094 and EMT-related proteins were markedly upregulated in nasal polyp tissues of CRSwNP. LINC01094 knockdown inhibited IL-13-induced hNEC EMT and pyroptosis. LINC01094 promoted HMGB1 expression in CRSwNP by binding with FUS. HMGB1 promoted Snail nuclear import in GSK-B phosphorylation-dependent manner. CONCLUSION LINC01094 facilitated hNEC EMT and pyroptosis in CRSwNP by activating the HMGB1/GSK-B Snail axis, which suggested that LINC01094 might serve as a biomarker and therapeutic target in CRSwNP.

Abstract
Type 2 diabetes (T2D) is characterized by increased levels of blood glucose but is increasingly recognized as a heterogeneous disease, especially its multiple discrete cardiovascular phenotypes. Genetic variations play key roles in the heterogeneity of diabetic cardiovascular phenotypes. This study investigates possible associations of ATP-sensitive potassium channel (KATP) variants with cardiovascular phenotypes among the Chinese patients with T2D. Six hundred thirty-six patients with T2D and 634 non-diabetic individuals were analyzed in the study. Nine KATP variants were determined by MassARRAY. The KATP rs2285676 (AA + GA, OR = 1.43, 95% CI: 1.13–1.81, P = 0.003), rs1799858 (CC, OR = 1.42, 95% CI: 1.12–1.78, P = 0.004), and rs141294036 (CC, OR = 1.45, 95% CI: 1.15–1.83, P = 0.002) are associated with increased T2D risk. A follow-up of at least 45.8-months (median) indicates further association between the 3 variants and risks of diabetic-related cardiovascular conditions. The associations are categorized as follows: new-onset/recurrent acute coronary syndrome (ACS) (rs2285676/AA + GA, HR = 1.37, 95% CI: 1.10–1.70, P = 0.005; rs141294036/TT + CT, HR = 1.59, 95% CI: 1.28–1.99, P < 0.001), new-onset stroke (rs1799858/CC, HR = 2.58, 95% CI: 1.22–5.43, P = 0.013; rs141294036/CC, HR = 2.30, 95% CI: 1.16–4.55, P = 0.017), new-onset of heart failure (HF) (rs1799858/TT + CT, HR = 2.78, 95% CI: 2.07–3.74, P < 0.001; rs141294036/TT + CT, HR = 1.45, 95% CI: 1.07–1.96, P = 0.015), and new-onset atrial fibrillation (AF) (rs1799858/TT + CT, HR = 2.05, 95% CI: 1.25–3.37, P = 0.004; rs141294036/CC, HR = 2.31, 95% CI: 1.40–3.82, P = 0.001). In particular, the CC genotype of rs1799858 (OR = 2.38, 95% CI: 1.11–5.10, P = 0.025) and rs141294036 (OR = 1.95, 95% CI: 1.04–3.66, P = 0.037) are only associated with the risk of ischemic stroke while its counterpart genotype (TT + CT) is associated with the risks of HF with preserved ejection fraction (HFpEF) (rs1799858, OR = 3.46, 95% CI: 2.31–5.18, P < 0.001) and HF with mildly reduced ejection fraction (HFmrEF) (rs141294036, OR = 2.74, 95% CI: 1.05–7.15, P = 0.039). Furthermore, the 3 variants are associated with increased risks of abnormal serum levels of triglyceride (TIRG) (≥ 1.70 mmol/L), low-density lipoprotein cholesterol (LDL-C) (≥ 1.40 mmol/L), apolipoprotein B (ApoB) (≥ 80 mg/dL), apolipoprotein A-I (ApoA-I) level (< 120 mg/dL), lipoprotein(a) Lp(a) (≥ 300 mg/dL) and high-sensitivity C-reactive protein (HsCRP) (≥ 3.0 mg/L) but exhibited heterogeneity (all P < 0.05). The KATP rs2285676, rs1799858, and rs141294036 are associated with increased risks of T2D and its related cardiovascular phenotypes (ACS, stroke, HF, and AF), but show heterogeneity. The 3 KATP variants may be promising markers for diabetic cardiovascular events favoring “genotype-phenotype” oriented prevention and treatment strategies.

Abstract
目的 探究MYC/BCL-2蛋白双表达对弥漫大B细胞淋巴瘤(DLBCL)患者预后的影响,观察纳入DA-EPOCH-R(利妥昔单抗+依托泊苷+泼尼松+长春新碱+环磷酰胺+表阿霉素)、中枢神经系统预防治疗、移植等治疗因素后,双表达是否仍是DLBCL的独立预后不良因素。 方法 回顾性收集2015−2018年在北京协和医院血液科治疗且具有可用病理结果的223例初治DLBCL患者,75例MYC/BCL-2高表达的患者归为双表达组,从148例非双表达的患者中,应用倾向性评分(PSM),根据年龄、国际预后指数(IPI)评分、治疗选择等因素进行1∶1匹配,筛选出75例作为对照组,比较两组患者总生存(OS)及无进展生存(PFS)等方面的差异。 结果 PSM后双表达组和非双表达组的3年OS率分别为(69.8±5.5)%及(77.0±4.9)%(P=0.225),3年PFS率分别为(60.7±5.8)%及(65.3±5.5)%(P=0.390),差异均无统计学意义。R-CHOP方案(利妥昔单抗+环磷酰胺+阿霉素+长春新碱+泼尼松)治疗的亚组分析显示,双表达和非双表达患者的3年OS率分别为(61.3±7.5)%及(77.2±5.6)%(P=0.027),3年PFS率分别为(52.1±7.5)%及(70.6 ± 6.0)%(P=0.040),差异均具有统计学意义。多因素Cox回归分析显示年龄、Ann Arbor分期、细胞起源(COO)分型、是否进行中枢神经系统预防、是否进行移植是DLBCL患者预后的独立影响因素(P值均<0.05),而MYC/BCL-2蛋白双表达不是预后的影响因素。 结论 MYC/BCL-2蛋白双表达在R-CHOP方案治疗下与不良预后显著相关,但在DA-EPOCH-R、移植等治疗方案下,双表达对DLBCL的不良预后影响在一定程度上得到消除。

Abstract
CONTEXT Lower serum concentration of apolipoprotein A-I (ApoA-I) is causally associated with heart failure (HF) risk. Adenosine triphosphate-sensitive potassium channels (KATP), as gating channels coupling vascular reactivity and metabolism with ischemic protection, become a new potential target of management for HF. The KATP gene sequence is highly polymorphic and has a high degree of genetic heterogeneity. OBJECTIVE This work aimed to determine whether KATP variants predict the risks of decreased ApoA-I concentration and its related HF. METHODS A total of 634 individuals, including 317 patients with decreased ApoA-I concentration (< 120 mg/dL) and 317 counterpart participants (≥ 120 mg/dL), were retrospectively selected. Five KATP variants were genotyped through the MassARRAY platform. Exosome-derived microRNAs (exo-miRs) expression profiles were identified by next-generation sequencing, and the top 10 differentially expressed (DE) exo-miRs were verified using quantitative polymerase chain reaction in a validation cohort of 240 individuals with decreased ApoA-I concentration. RESULTS KATP rs141294036 was related to an increased risk of lower ApoA-I levels (adjusted odds ratio [OR] = 1.95, P = .002) and HF incidence (adjusted OR = 2.38, P = .009), especially heart failure with preserved ejection fraction (HFpEF; adjusted OR = 2.13, P = .015). After a median 48.6-month follow-up, participants carrying the CC genotype of rs141294036 were associated with an elevated HF rehospitalization risk (adjusted hazard ratio = 1.91, P = .005). Thirty-six exo-miRs were significantly DE between different genotypes of rs141294036 in participants with lower ApoA-I levels, but only 5 exo-miRs (miR-31-5p, miR-126-5p, miR-106a-5p, miR-378i, and miR-181c-5p) were further confirmed. CONCLUSION KATP rs141294036 was associated with increased risks of lower ApoA-I levels, HF incidence (especially HFpEF), and HF rehospitalization in those with the 5 confirmed exo-miRs and its related metabolic pathways.

Abstract
AIM To investigate machine learning based models combining clinical, radiomic, and molecular information to distinguish between early true progression (tPD) and pseudoprogression (psPD) in patients with glioblastoma. MATERIALS AND METHODS A retrospective analysis was undertaken of 76 patients (46 tPD, 30 psPD) with early enhancing disease following chemoradiotherapy for glioblastoma. Outcome was determined on follow-up until 6 months post-chemoradiotherapy. Models comprised clinical characteristics, O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status, and 307 quantitative imaging features extracted from enhancing disease and perilesional oedema masks on early post-chemoradiotherapy contrast-enhanced T1-weighted imaging, T2-weighted imaging (T2WI), and apparent diffusion coefficient (ADC) maps. Feature selection was performed within bootstrapped cross-validated recursive feature elimination with a random forest algorithm. Naive Bayes five-fold cross-validation was used to validate the final model. RESULTS Top selected features included age, MGMT promoter methylation status, two shape-based features from the enhancing disease mask, three radiomic features from the enhancing disease mask on ADC, and one radiomic feature from the perilesional oedema mask on T2WI. The final model had an area under the receiver operating characteristics curve (AUC) of 0.80, sensitivity 78.2%, specificity 66.7%, and accuracy of 73.7%. CONCLUSION Incorporating a machine learning-based approach using quantitative radiomic features from standard-of-care magnetic resonance imaging (MRI), in combination with clinical characteristics and MGMT promoter methylation status has a complementary effect and improves model performance for early prediction of glioblastoma treatment response.

Abstract
Serum concentration of apolipoprotein B (Apo B) is causally associated with arteriosclerosis cardiovascular disease (ASCVD) risk. Whether ATP-sensitive potassium channels (KATP) variants predict the risk of increased Apo B concentration (≥ 80 mg/dL) and related ASCVD remain less clear. We recruited 522 subjects with elevated Apo B concentration (≥ 80 mg/dL) and 522 counterpart subjects (< 80 mg/dL) from South China to assess the associations of KATP variants (rs11046182, rs78148713, rs145456027 and rs147265929) with the risks of increased Apo B serum concentration (≥ 80 mg/dL), carotid artery stenosis (CAS) ≥ 50% and new-onset ischemic stroke (IS). Our results showed that only KATP SNP rs11046182 (GG genotype) was associated with increased risk of Apo B ≥ 80 mg/dL (adjusted OR=2.17, P<0.001) and CAS ≥ 50% (adjusted OR=2.63, P=0.011). After median 50.6-months follow-up, subjects carrying GG genotype of rs11046182 were associated with higher risk of new-onset IS (adjusted HR=2.24, P=0.024). Further, the exosome-derived microRNAs (exo-miRs) expression profile was identified by next-generation sequencing. 41 exo-miRs were significantly differentially expressed under cross-talk status between high Apo B level (≥ 80 mg/dL) and KATP rs11046182. Our study demonstrated that KATP variant rs11046182 was associated with higher risks of elevated serum Apo B levels and its related ASCVD, and the possible mechanism was related to specific exo-miRs expression profile of KATP rs11046182.

Abstract
Background Exosome-derived microRNAs (exo-miRs) as messengers play important roles, in the cross-talk between genetic [ATP-sensitive potassium channels (KATP) genetic variant rs1799858] and environmental [elevated serum low-density lipoprotein cholesterol (LDL-C) level] factors, but the plasma exo-miRs expression profile and its role in biological processes from genotype to phenotype remain unclear. Methods A total of 14 subjects with increased LDL-C serum levels (≥ 1.8 mmol/L) were enrolled in the study. The KATP rs1799858 was genotyped by the Sequenom MassARRAY system. The plasma exo-miRs expression profile was identified by next-generation sequencing. Results 64 exo-miRs were significantly differentially expressed (DE), among which 44 exo-miRs were up-regulated and 20 exo-miRs were down-regulated in those subjects carrying T-allele (TT + CT) of rs1799858 compared to those carrying CC genotype. The top 20 up-regulated DE-exo-miRs were miR-378 family, miR-320 family, miR-208 family, miR-483-5p, miR-22-3p, miR-490-3p, miR-6515-5p, miR-31-5p, miR-210-3p, miR-17-3p, miR-6807-5p, miR-497-5p, miR-33a-5p, miR-3611 and miR-126-5p. The top 20 down-regulated DE-exo-miRs were let-7 family, miR-221/222 family, miR-619-5p, miR-6780a-5p, miR-641, miR-200a-5p, miR-581, miR-605-3p, miR-548ar-3p, miR-135a-3p, miR-451b, miR-509-3-5p, miR-4664-3p and miR-224-5p. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were subsequently implemented to identify the top 10 DE-exo-miRs related specific target genes and signaling pathways. Only 5 DE-exo-miRs were validated by qRT-PCR as follows: miR-31-5p, miR-378d, miR-619-5p, miR-320a-3p and let-7a-5p (all P < 0.05). Conclusion These results firstly indicated the plasma exo-miRs expression profile bridging the link between genotype (KATP rs1799858) and phenotype (higher LDL-C serum level), these 5 DE-exo-miRs may be potential target intermediates for molecular intervention points.

Abstract
In this paper, we introduce a new definition for nilpotent fuzzy Lie ideal, which is a well-defined extension of nilpotent Lie ideal in Lie algebras, and we name it a good nilpotent fuzzy Lie ideal. Then we prove that a Lie algebra is nilpotent if and only if any fuzzy Lie ideal of it, is a good nilpotent fuzzy Lie ideal. In particular, we construct a nilpotent Lie algebra via a good nilpotent fuzzy Lie ideal. Also, we prove that with some conditions, every good nilpotent fuzzy Lie ideal is finite. Finally, we define an Engel fuzzy Lie ideal, and we show that every Engel fuzzy Lie ideal of a finite Lie algebra is a good nilpotent fuzzy Lie ideal. We think that these notions could be useful to solve some problems of Lie algebras with nilpotent fuzzy Lie ideals.

Abstract
In recent years, bariatric surgery has emerged as a promising treatment for type 2 diabetes. Bariatric surgery is known to cause alterations in the relative abundance and composition of gut microbiota, which may lead to alterations in the levels of Short-Chain Fatty Acids (SCFAs) that are produced during fermentation by gut microbes. However, little is known about the mechanism of improved glucose metabolism mediated by gut microbiota following bariatric surgery. The aim of our study was to explore whether changes in gut microbiota and in fecal SCFA could be detected following single-anastomosis duodenal jejunal bypass (DJB-sa) surgery, a type of bariatric surgery, and whether these alterations might be related to the improvement of glucose metabolism. To this end, we performed DJB-sa or SHAM surgery on Goto-Kakisaki (GK) rats. We then compared the glucose metabolism as well as changes in gut microbiota and SCFAs levels between both groups. Our results showed that DJB-sa surgery was associated with a significant decrease in fasting blood glucose (FBG), intraperitoneal glucose tolerance test (IPGTT), and fasting serum insulin (FSI). And, DJB-sa led to a change in the composition of gut microbiota including an increase in the relative abundance of SCFA-producing bacteria (Bifidobacterium and Subdoligranulum). Moreover, the levels of six SCFAs in feces, as well as the intestinal expression of SCFA receptors including G-protein-coupled receptor 41 (GPR41), G-protein-coupled receptor 43 (GPR43), and G-protein-coupled receptor 109A (GPR109A), and the expression of Glucagon-like peptide-1 (GLP-1) displayed a significant increase following DJB-sa compared with the Sham group. Thus, the gut microbiota may contribute to the improvement of glucose metabolism in type 2 diabetes following DJB-sa. In conclusion, our study shows that DJB-sa improves glucose metabolism by modulating gut microbiota and by increasing short-chain fatty acid production.

Abstract
Objective: To analyze the infection status and recombination of Norovirus in patients with acute gastroenteritis in Ningxia. Methods: The specimens of 10 sentinel hospitals in Ningxia were collected from 2016 to 2017. Real-time quantitative PCR was used for nucleic acid detection. GⅡ-positive samples were amplified by RT-PCR for the RdRp and Capsid regions, then sequenced and genotyped. Evolution analysis was performed using software such as MEGA-X, and recombination analysis was performed using Simplot 3.5.1 and RDP4. Results: The age of the 2 334 cases was 1.42 (0.68, 7.69) years old, 1 133 cases in 2016 and 1 201 cases in 2017, 1 343 and 991 cases for males and females respectively. The positive rate of Norovirus GⅠ genogroup was 0.86% (20/2 334), and GⅡ genogroup was 14.82% (346/2 334). A total of 78 recombinant strains were sequenced and 12 recombinant types were found. GⅡ.Pe/GⅡ.4Sydney_2012 and GⅡ.P12/GⅡ.3 were the main epidemic strains, accounting for 35.90% (28 strains) and 32.05% (25 strain) respectively, followed by GⅡ.P16/GⅡ.2 accounting for 12.82% (10 strains). Among them,GⅡ.P7/GⅡ.6 (2 strains), GⅡ.P12/GⅡ.3 (6 strains), GⅡ.P16/GⅡ.1 (2 strains), GⅡ.P16/GⅡ.2 (5 strains), GⅡ.Pe/GⅡ.4 (7 strains) were detected for the first time in Ningxia. Recombinant strains were all intergenotype recombination, and the recombination breakpionts were all located within ORF1. Conclusion: Norovirus infection in Ningxia area was mainly in GⅡ genogroup from 2016 to 2017, and most of them were recombinant strains. GⅡ.Pe/GⅡ.4Sydney_2012 and GⅡ.P12/GⅡ.3 were the main epidemic strains, followed by GⅡ.P16/GⅡ. 2.

Abstract
AIMS To establish the biotechnology platforms for production of bio-based chemicals in various micro-organisms is considered as a promising target to improve renewable production of isoprene. METHODS AND RESULTS In this study, we heterologously expressed the mevalonate (MVA) isoprene biosynthesis pathway, and explored three strategies of increasing isoprene production in Escherichia coli. We first manipulated the expression levels of the MVA pathway genes through changing the gene cassettes and promoters. To introduce cofactor engineering, we then overexpressed NADP-dependent glyceraldehyde-3-phosphate dehydrogenase gene from Clostridium acetobutylicum to supply available NADPH. To reduce the inhibitory by-product accumulation, we finally knocked out acetate-producing genes, phosphate acetyl transferase and pyruvate oxidase B in E. coliJM109 (DE3), decreasing acetate accumulation 89% and increasing isoprene production 39%. The strategies described here finally increased the isoprene titre to 92 mg l-1 in two-gene deletion strain JMAB-4T7P1Trc, increasing 2·6-fold comparing to strain JM7T7. CONCLUSION The multimodularly engineering approaches including promoter engineering, cofactor engineering and by-product reducing could be used to improve isoprene production in E. coli. SIGNIFICANCE AND IMPACT OF THE STUDY The metabolic strategies in this study show us directions for further studies to promote transformation of renewable sources to isoprene.

Abstract
BACKGROUND Current studies indicate that inflammation of white adipose tissue (WAT) is a pathogenic characteristic of insulin resistance. However, the significance of visceral WAT inflammation after bariatric surgery remains unclear. METHODS Duodenojejunal bypass plus sleeve gastrectomy (DJB-SG) was performed on Goto-Kakisaki rats. Weight, fasting blood glucose (FBG), and homeostatic model assessment of insulin resistance (HOMA-IR) in the DJB-SG group were compared to those in a sham surgery (SHAM) group every 2 weeks. The results of an oral glucose tolerance test (OGTT) and the volume of visceral adipose tissue (Visc.Fat) were compared before and 8 weeks postsurgery. Eight weeks after surgery, the rats were sacrificed and visceral WAT collected from the greater omentum. Tumor necrosis factor-α (TNF-α) and cluster of differentiation 68 (CD68) expression in the WAT were evaluated in paraffin-embedded sections by immunohistochemistry. RESULTS Compared with the SHAM group, the DJB-SG group demonstrated a significant reduction in weight, FBG, and HOMA-IR (P < 0.05), with elevation of insulin levels (P < 0.05) from 4 weeks after surgery. OGTT and the quantity of Visc.Fat were significantly reduced (P < 0.05) 8 weeks after surgery. Moreover, the expression of TNF-α and CD68 in the visceral white adipose tissue was significantly lower 8 weeks after surgery (P < 0.05). CONCLUSIONS The DJB-SG model established in Goto-Kakisaki rats achieved anticipated efficacy. Reduced TNF-α-related inflammation in visceral WAT may result in improved insulin resistance.

Abstract
Bariatric surgery is currently the most effective strategy in treating severe obesity and its comorbidities, such as type 2 diabetes (T2D). However, the mechanism through which bariatric surgery mediates its benefits is not completely understood. Since obesity and T2D represent yet another inflammatory disease, and follicular helper T (Tfh) cells play important roles in inflammatory disorders, we investigated whether the Tfh activity was altered after Roux-en-Y gastric bypass (RYGB), one of the most common bariatric surgery procedures. We found that the Tfh cells after RYGB were not significantly changed in number, but presented altered cytokine secretion profile, including lower interferon (IFN)-γ, interleukin (IL)-2, IL-4, and IL-17 secretion. Tfh cells after RYGB also downregulated inducible co-stimulator and programmed death-1. Interestingly, after Tfh cell-naive B cell coculture, Tfh cells after RYGB secreted more IL-10 than autologous Tfh cells before RYGB. The frequencies of IL-10-expressing and transforming growth factor (TGF)-β-expressing regulatory B cells after Tfh cell-naive B cell coculture were directly correlated with the frequency of IL-10-expressing Tfh cells. Depletion of IL-10 in the coculture, however, resulted in fewer regulatory B cells. Finally, patients with greater increase in IL-10-expressing Tfh cells presented further reductions in body mass index, glycaemia, and body fat percentage. Together, these data demonstrated that the Tfh cells after RYGB presented lower inflammatory status and secreted higher IL-10, through which these Tfh cells promoted the development of regulatory B cells. Higher IL-10-expressing Tfh cell level also predicted better patient response to RYGB.

Abstract
Bariatric surgeries, including Roux-en-Y gastric bypass (RYGB) are currently the best treatment for obesity and obesity-related comorbidities, such as type 2 diabetes. However, the underlying mechanism of bariatric surgeries is not entirely understood. Further investigations are needed to improve the success rate and achieve sustained health benefits. Given that B cell dysregulation is a critical component of etiology in inflammatory diseases, whereas obesity and type 2 diabetes represent two major inflammatory disorders, we investigated the effect of RYGB on B cell inflammation. We found that B cells after RYGB presented significantly elevated frequency of interleukin (IL)-10-producing cells and reduced frequency of IL-6-producing cells compared to those before RYGB. When grouping B cell subsets into regulatory (secreting IL-10 and transforming growth factor beta [TGF-β]) and effector (secreting IL-2, IL-4, IL-6, IL-12, interferon gamma [IFN-γ] and tumor necrosis factor alpha [TNF-α]) types, we found that after RYGB, the regulatory to effector B cell ratio was significantly increased. Function analyses showed that B cells before RYGB supported IL-17 secretion from T cells whereas these cells after RYGB lost such capacity. B cells after RYGB also gained the capacity to suppress T cell IFN-γ production through TGF-β-mediated effects, a feature not present in B cells before RYGB. Interestingly, the regulatory to effector B cell ratio was directly associated with the reductions in obesity markers following RYGB, such as BMI and fat mass percentage. Together, these results demonstrated a potential mechanism through which RYGB promoted amelioration of obesity and type 2 diabetes.

Abstract
BACKGROUND Adaptive behaviour is closely related to quality of life in children with intellectual disability (ID), but little is known about the adaptive behaviour of children with fragile X syndrome (FXS) in China. METHOD In boys with FXS, the adaptive behaviours in six domains, including self-dependence, locomotion, work skills, communication, socialisation and self-management, were assessed by the Infants-Junior Middle School Students Social-life Abilities Scale. In addition, we compared the adaptive skills of boys with FXS to those of three control groups of boys, including boys with Down syndrome (DS) and typically developing (TD) boys matched by chronological age (CA) or mental age (MA). The profile of the adaptive behaviour of boys with FXS is discussed in detail. RESULTS Compared to boys with DS, boys with FXS obtained lower scores in three domains in adaptive behaviour, including work skills, socialisation and self-management skills; boys with FXS had better scores in self-dependence and locomotion skills than boys matched for MA; as expected, boys with FXS had significantly poorer adaptive skills in all six domains assessed compared to CA boys. CONCLUSION The development of adaptive skills in boys with FXS was worse than that of boys with DS. The profile of the adaptive behaviour of boys with FXS establishes a basis for the development of targeted interventions to promote social development in this population.

Abstract
Type 2 diabetes (T2D) is a chronic metabolic disorder, which was also found to involve a series of inflammatory disorders, including accumulation of macrophages and T cells in the adipose tissue, increased proinflammatory cytokine production, shifting of macrophage composition toward M1-type, and skewing of peripheral blood T cells toward IL-17 productions. However, these studies were primarily conducted in obese mouse models and/or human subjects with higher BMI, and may not reflect the role of the immune system in non-obese T2D pathogenesis. Here, we examined T cell and monocyte cytokine expression and function in both non-obese and obese T2D patients. We found that IFN-g production by circulating T cells were increased in both non-obese and obese T2D subjects, while IL-17 is only upregulated in obese T2D subjects. Also, circulating monocytes from obese T2D subjects had significantly higher IL-6 production than their counterparts in non-obese T2D subjects. Moreover, monocytes from non-obese T2D subjects could support IFN-g but not IL-17 production in vitro, while that from obese T2D subjects supported both IFN-g and IL-17 production. Together, our results revealed that the role immune system plays in T2D pathogenesis is more complicated than previously thought, and is affected by the person's BMI.

Abstract
Mechanisms of type 2 diabetes mellitus (T2DM) remain elusive, in which obesity (OB) is considered as one of the major risk factors for the disease. A microRNA (miRNA) is a small non-coding RNA molecule functioning in RNA silencing and post-transcriptional regulation of gene expression. It has been demonstrated that some miRNAs can exist in serum stably and is closely related to various diseases. The goal of our study was to identify whether the deregulation of serum miRNAs was associated with T2DM and obesity. Twenty-five subjects with T2DM2, 25 healthy controls, 25 subjects with obesity, and 25 subjects with T2DM combined with obesity were included in the study. A total of 536 miRNA serum samples from these four groups were studied by miRNA polymerase chain reaction (PCR) panels. Data showed that miR-152 and miR-17 were significantly elevated in the OB group, whereas miR-138 was significantly decreased in OB group when compared to controls, T2DM, or T2DM+obesity group. In addition, level of MiR-593 was significantly lower in T2DM group and T2DM+obesity group when compared with controls. Further analysis revealed that the four miRNAs can be used as potential biomarkers to distinguish obesity from T2DM, OB+T2DM, and healthy subjects. Our study is one of the pioneer studies showing the differences in peripheral miRNA level in obesity, T2DM and T2DM combined with obesity. The study results suggest the potential utility of miRNAs in the prediction for obesity and T2DM.

Abstract
β-arrestins are expressed proteins that were first described, and are well-known, as negative regulators of G protein-coupled receptor signaling. Penehyclidine hydrochloride (PHC) is a new anti-cholinergic drug that can inhibit biomembrane lipid peroxidation, and decrease cytokines and oxyradicals. However, to date, no reports on the effects of PHC on β-arrestin-1 in cells have been published. The aim of this study was to investigate the effect of PHC on β-arrestin-1 expression in lipopolysaccharide (LPS)-induced human pulmonary microvascular endothelial cells (HPMEC). Cultured HPMEC were pretreated with PHC, followed by LPS treatment. Muscarinic receptor mRNAs were assayed by real-time quantitative PCR. Cell viability was assayed by the methyl thiazolyl tetrazolium (MTT) conversion test. The dose and time effects of PHC on β-arrestin-1 expression in LPS-induced HPMEC were determined by Western blot analysis. Cell malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were measured. It was found that the M3 receptor was the one most highly expressed, and was activated 5 min after LPS challenge. Furthermore, 2 μg/mL PHC significantly upregulated expression of β-arrestin-1 within 10 to 15 min. Compared with the control group, MDA levels in cells were remarkably increased and SOD activities were significantly decreased in LPS pretreated cells, while PHC markedly decreased MDA levels and increased SOD activities. We conclude that PHC attenuated ROS injury by upregulating β-arrestin-1 expression, thereby implicating a mechanism by which PHC may exert its protective effects against LPS-induced pulmonary microvascular endothelial cell injury.

Abstract
CONTEXT Although transumbilical single incision laparoscopic cholecystectomy (SILC) has been demonstrated to be superior cosmetic, it is only limited to simple cases at present. In complex cases, the standard four- or three-port LC is still the treatment of choice. AIM To summarize the clinical effect of a modified technique in two-port LC. SETTINGS AND DESIGN A consecutive series of patients with benign gallbladder diseases admitted to the provincial teaching hospital who underwent LC in the past 4 years were included. A modified two-port LC was the first choice except for those requiring laparoscopic common bile duct exploration (LCBDE). MATERIALS AND METHODS The operation was done with suture retraction of the fundus by a needle-like retractor. The patients' data, including the operative time, time consumed by gallbladder retraction, operative bleeding, conversion rate, rate of adding trocars, and postoperative complications were recorded. STATISTICAL ANALYSIS Data were expressed as percentage and mean with standard deviation. RESULTS Total 107 patients with chronic calculous cholecystitis (N = 61), acute calculous cholecystitis (N = 43), and cholecystic polyps (N = 3) received two-port LC. The procedure was successful in 99 out of 107 cases (success rate, 92.5%), and a third trocar was added in the remaining 8 cases (7.5%) due to severe pathological changes. The operative time was 47.2 (±13.21) min. There was no conversion to open surgery. CONCLUSION Two-port LC using a needle-like retractor for suture retraction of the gallbladder fundus is a practical approach when considering the safety, convenience, and indications as well as relatively minimal invasion.

Abstract
Ischemia/reperfusion injury (IRI) is the most common cause of early mortality following lung transplantation (LTx). We hypothesized that nitrite, an endogenous source of nitric oxide (NO), may protect lung grafts from IRI. Rat lung grafts were stored in preservation solution at 4°C for 6 hours. Both grafts and recipients were treated with nitrite. Nitrite treatment was associated with significantly higher levels of tissue oxygenation, lower levels of cytokines and neutrophil/macrophage infiltration, lower myeloperoxidase activity, reduced oxidative injury and increased cGMP levels in grafts than in the controls. Treatment with either a nitric oxide scavenger or a soluble guanylyl cyclase (sGC) inhibitor diminished the beneficial effects of nitrite and decreased cGMP concentrations. These results suggest that nitric oxide, generated from nitrite, is the molecule responsible for the effects of nitrite via the nitric oxide/sGC/cGMP pathway. Allopurinol, a xanthine oxidoreductase (XOR) inhibitor, abrogated the protective effects of nitrite, suggesting that XOR is a key enzyme in the conversion of nitrite to nitric oxide. In vitro experiments demonstrated that nitrite prevented apoptosis in pulmonary endothelial cells. Nitrite also exhibits longer survival rate in recipients than control. In conclusion, nitrite inhibits lung IRI following cold preservation and had higher survival rate in LTx model.

Abstract
The articular disc plays an important role as a stress absorber in joint movement, resulting in stress reduction and redistribution in the temporomandibular joint (TMJ). The flow of synovial fluid in the TMJ may follow a regular pattern during movement of the jaw. We hypothesised that the regular pattern is disrupted when the TMJ disc is perforated. By computed tomography arthrography, we studied the upper TMJ compartment in patients with small disc perforation during jaw opening-closing at positions from 0 to 3 cm. Finite element fluid dynamic modelling was accomplished to analyse the pattern of fluid flow and pressure distribution during the movements. The results showed that the fluid flow in the upper compartment generally formed an anticlockwise circulation but with local vortexes with the jaw opening up to 2 cm. However, when the jaw opening-closing reached 3 cm, an abnormal flow field and the fluid pressure change associated with the perforation may increase the risk of perforation expansion or rupture and is unfavourable for self-repair of the perforated disc.

Abstract
Mammosphere culture of cancer cell lines is an important approach used for enrichment of stem-like cancer cells (SLCs), but over-subcultured cell lines have been experimentally shown to change properties over time. It remains unclear if mammosphere cells (MSs) derived from high-passage cancer cell lines retain the tumorigenicity and radioresistance seen in MSs from primary or low-passage cell lines. In this study, we report that mammospheres derived from MCF-7 sublines after different passage numbers were consistently enriched for CD44+/CD24(-/low) cells but were not consistently enriched for tumorigenic and radioresistant cells. The tumorigenicity and radioresistance of MSs were associated with their sphere-forming ability, proliferation ability in vitro, and intracellular reactive oxygen species (ROS) levels. The radioresistant MSs showed significant cell cycle arrest in G2/M phase after X-ray irradiation and expressed higher ataxia telangiectasia mutated (ATM) mRNA levels. These results suggest that MSs from high-passage cancer cell lines were not consistently enriched for stem-like cancer cells with higher tumorigenicity and enhanced radioresistance.

Abstract
e14624 Background: Thrombopoietin (TPO) interacts with its receptor (mpl) to initiate signal transduction and increase platelet production. Other mpl agonists have been developed for clinical use: MDGF (a recombinant protein) and romiplostim (a peptibody) are protein-based mpl agonists; eltrombopag (a small molecule) is a nonpeptide mpl agonist. Methods: Mpl agonists were compared for their ability to induce cellular responses and activate relevant signaling pathways in mpl-expressing cells. Proliferation was assessed by ATP bioluminescence in Baf3/mpl cells treated with mpl agonists for 2 days. Differentiation was assessed by flow cytometric-detection of CD41 and CD61 expression on human CD34+ cells cultured with mpl agonists for 7 days. Activation of signaling pathways was determined by Western blot analysis of proteins from serum-starved Baf3/mpl cells treated with mpl agonists for 20 minutes. Experiments were repeated 3 or more times. Results: The TPO concentration that produced a half-maximal (EC50) proliferative response of Baf3/mpl cells was comparable with that of romiplostim (Table). In contrast, a 30-fold greater concentration of MGDF and a 2,000-fold greater concentration of small molecule were required to produce the same degree of proliferation. In addition, a 1,000,000-fold greater concentration of small molecule compared with romiplostim was required to produce an EC50 for differentiation of CD34+ cells. Mpl agonists activated identical signaling pathways in Baf3/mpl cells: a similar dose-response for phosphorylation of JAK2, Stat3, Stat5, Erk1/2, and AKT was observed at their respective EC10, EC50, and EC100 concentrations. Conclusions: In Baf3/mpl cells, the small molecule was between 1,000- and 1,000,000-fold less potent than protein-based mpl agonists when corrected for molecular mass differences. Small molecule and protein-based mpl agonists were indistinguishable when mpl intracellular signaling was compared at similarly effective concentrations. [Table: see text] [Table: see text]

Abstract
The aim of the study was to investigate the effects of two anaesthetic techniques (total intravenous technique vs. inhalational technique) on changes in pro- and anti-inflammatory cytokine levels during open cholecystectomy. Forty ASA PS I-II patients undergoing open cholecystectomy were randomly assigned to two groups. Group R received total intravenous anaesthesia with propofol and remifentanil and group F received balanced inhalational anaesthesia with isoflurane. The plasma levels of tumour necrosis factor-alpha (TNF-alpha), interleukin IL-6 and interleukin IL-10 were measured during and after surgery. The pro-inflammatory cytokine levels (TNF-alpha and IL-6) and the anti-inflammatory cytokine (IL-10) showed a significant increase in their concentrations compared with pre-induction levels in both groups (P < 0.05). By the end of anaesthesia and surgery, TNF-alpha and IL-6 were significantly lower in group R than in group F (P < 0.05). At the end of anaesthesia and 12 hours postoperatively, IL-10 levels in group R were higher than in group F (P < 0.05). These findings suggest that total intravenous anaesthesia using propofol and remifentanil suppresses the inflammatory response caused by surgery to a greater extent than a balanced inhalation technique using isoflurane.
