Abstract
INTRODUCTION Minimal invasive plate osteosynthesis (MIPO) is one of the most important techniques in the treatment for humeral shaft fractures. This study was performed to evaluate the efficacy of MIPO technique for the treatment for humeral shaft fractures. MATERIALS AND METHODS We retrospectively evaluated 128 cases with humeral shaft fractures that were treated with MIPO technique from March 2005 to August 2008. All the patients were followed up by routine radiological imaging and clinical examinations. Constant-Murley score and HSS elbow joint score were used to evaluate the treatment outcome. RESULTS The average duration of the surgery was 60 min (range 40-95 min) without blood transfusion. All fractures healed without infection. All cases recovered carrying angle except four cases with 10°-15° cubitus varus. After the average follow-up of 23 (13-38) months, satisfactory function was achieved according to Constant-Murley score and HSS elbow joint score. Constant-Murley score was 80 on average (range 68-91). According to HSS elbow joint score, there were 123 cases of excellent clinical outcome and five cases of effective outcome. CONCLUSION It seems to be a safe and effective method for managing humeral shaft fractures with MIPO technique.

Abstract
The aim of this meta-analysis was to evaluate the correlations between the estrogen receptor 1 (ESR1) gene polymorphisms PvuII (rs2234693T>C) and XbaI (rs9340799A>G) and the risk of cardiovascular disease (CVD). Case-control studies were screened and selected from a larger group of studies that were retrieved through a comprehensive search of scientific literature databases, which was complemented by manual searches. Data from studies selected were analyzed using the Comprehensive Meta-analysis 2.0 software. A total of 240 studies were initially retrieved and 10 studies were eventually included in the meta-analysis. These 10 case-control studies involved 7029 CVD patients (5001 myocardial infarction patients, 1223 coronary artery disease patients, 805 acute coronary syndromes patients) and 6901 healthy controls. We found no significant association between the PvuII (rs2234693T>C) and XbaI (rs9340799A>G) polymorphisms and CVD risk. We detected no significant associations under all genetic inheritance models tested, including the allele, dominant, homozygous, heterozygous, and recessive models, or for comparisons between the case group and control group (all P > 0.05). Our meta-analysis results strongly suggest that the ESR1 gene polymorphisms PvuII (rs2234693T>C) and XbaI (rs9340799A>G) are not associated with CVD risk.

Abstract
Cystic echinococcosis (CE) is an important worldwide zoonotic disease that causes large economic losses and human suffering. Echinococcus granulosus, the causative agent of CE, exhibits different genotypes in different locations. In order to identify its genotypes and analyze its genetic structure on the Tibetan Plateau, we collected 72 hydatid cysts from different intermediate hosts and amplified and sequenced their mitochondrial cytochrome c oxidase subunit 2 (cox2) genes. Seventy isolates were identified as the E. granulosus G1 genotype, while two isolates belonged to the G6 genotype. There were 18 haplotypes among the 70 E. granulosus isolates, which exhibited a star-like network pattern and shared a common haplotype (H1). There was little difference between geographical sub-populations. Our results suggest that a recent E. granulosus population expansion occurred on the Tibetan Plateau, suggesting that E. granulosus was introduced into China. This study increases the basic molecular data needed for the molecular diagnosis, epidemiology, prevention, and control of Echinococcus diseases.

Abstract
Celiac disease (CD) is a common autoimmune disorder characterized by heightened immunological response to ingested gluten. Certain gene polymorphisms of IL2/IL21 (rs6822844 and rs6840978) and SH2B3 (rs3184504) may influence susceptibility to CD, although the effects remain unclear. We performed a meta-analysis of the associations between rs6822844, rs6840978, and rs3184504 polymorphisms and CD risk. PubMed, EMBASE, and the China National Knowledge Infrastructure were searched. ORs and 95%CIs of each single nucleotide polymorphism (SNP) were estimated using the fixed-effect model if I(2) < 50% in the test of heterogeneity; otherwise, the random-effect model was used. Our meta-analysis included 12,986 CD cases and 28,733 controls from 16 independent samples, and the analysis of each SNP contained a subset of the total. We found that the minor allele T of both rs6822844 (T vs G, OR = 0.72, 95%CI = 0.67-0.78, P < 0.001) and rs6840978 (T vs C, OR = 0.76, 95%CI = 0.71-0.83, P < 0.001) in IL2/IL21 significantly decreased the risk of CD. However, the minor allele A of rs3184504 (A vs G, OR = 1.18, 95%CI = 1.12-1.24, P < 0.001) in SH2B3 significantly increased CD susceptibility. The estimated lambda values were 0.49, 0.50, and 0.53 for rs6822844, rs6840978, and rs3184504, respectively, suggesting that a co-dominant model of genotype effect was most appropriate for the three SNPs. Our results support associations between the three SNPs and CD and provide a strong argument for further research.

Abstract
AIM To evaluate the correlations between renal cortical volume (RCV), renal parenchymal volume (RPV), and renal function in patients with renal tumours before and after laparoscopic partial nephrectomy (LPN). MATERIALS AND METHODS Thirty-five patients with a single unilateral renal tumour who had undergone contrast-enhanced computed tomography (CT) and renal nuclear scintigraphy before and after LPN were retrospectively studied. RCV and RPV were calculated as renal volume, excluding tumours or cysts, using a semi-automatic segmentation program. The correlations between RCV, RPV, and glomerular filtration rate (GFR) were undertaken preoperatively and postoperatively using the Pearson correlation coefficient. RESULTS Preoperatively, the correlations between RCV and GFR, and RPV and GFR for the operated kidneys was r=0.502 (p=0.002) and 0.527 (p=0.001), respectively, whereas the correlations for the contralateral side were r=0.384 (p=0.023) and r=0.412 (p=0.014). The mean RCV and RPV of the operated kidneys decreased by 27.4% and 24.8%. The mean split GFR of the operated kidneys decreased by 36.4%. Postoperatively, residual RCV (r=0.619, p<0.001) and RPV (r=0.593, p<0.001) correlated moderately with the GFR of the operated kidneys. CONCLUSIONS Renal volume, both RCV and RPV, had a moderate relationship with renal function before and after operation. CT-based renal volume measurements could serve as a simple and effective method for estimation of postoperative renal function.

Abstract
The anti-CD38 monoclonal antibody SAR650984 (SAR) is showing promising clinical activity in treatment of relapsed and refractory multiple myeloma (MM). Besides effector-mediated antibody-dependent cellular cytotoxicity and complement-mediated cytotoxicity, we here define molecular mechanisms of SAR-directed MM cell death and enhanced anti-MM activity triggered by SAR with Pomalidomide (Pom). Without Fc-cross-linking agents or effector cells, SAR specifically induces homotypic aggregation (HA)-associated cell death in MM cells dependent on the level of cell surface CD38 expression, actin cytoskeleton and membrane lipid raft. SAR and its F(ab)'2 fragments trigger caspase 3/7-dependent apoptosis in MM cells highly expressing CD38, even with p53 mutation. Importantly, SAR specifically induces lysosome-dependent cell death (LCD) by enlarging lysosomes and increasing lysosomal membrane permeabilization associated with leakage of cathepsin B and LAMP-1, regardless of the presence of interleukin-6 or bone marrow stromal cells. Conversely, the lysosomal vacuolar H+-ATPase inhibitor blocks SAR-induced LCD. SAR further upregulates reactive oxygen species. Pom enhances SAR-induced direct and indirect killing even in MM cells resistant to Pom/Len. Taken together, SAR is the first therapeutic monoclonal antibody mediating direct cytotoxicity against MM cells via multiple mechanisms of action. Our data show that Pom augments both direct and effector cell-mediated MM cytotoxicity of SAR, providing the framework for combination clinical trials.

Abstract
Molecular clockworks knit together diverse biological networks and compelling evidence from model systems infers their importance in metabolism, immunological and cardiovascular function. Despite this and the diurnal variation in many aspects of human physiology and the phenotypic expression of disease, our understanding of the role and importance of clock function and dysfunction in humans is modest. There are tantalizing hints of connection across the translational divide and some correlative evidence of gene variation and human disease but most of what we know derives from forced desynchrony protocols in controlled environments. We now have the ability to monitor quantitatively ex vivo or in vivo the genome, metabolome, proteome and microbiome of humans in the wild. Combining this capability, with the power of mobile telephony and the evolution of remote sensing, affords a new opportunity for deep phenotyping, including the characterization of diurnal behaviour and the assessment of the impact of the clock on approved drug function.

Abstract
BACKGROUND Duloxetine has been approved in the United States, European Union and some Asian countries for the treatment of diabetic peripheral neuropathic pain (DPNP). We assessed the efficacy and safety of duloxetine (60 mg once daily) compared with placebo in Chinese patients suffering from DPNP. METHODS This was a phase 3, multicenter, randomised, double-blind, parallel, placebo-controlled, 12-week trial of the treatment of DPNP with duloxetine. Subjects were male and female outpatients ≥ 18 years of age with DPNP, as assessed by the Michigan Neuropathy Screening Instrument, and had a rating of ≥ 4 on the Brief Pain Inventory-Modified Short Form-Severity weekly average pain item. The primary efficacy measure was the reduction in pain severity from baseline to 12 weeks, as measured by the weekly mean of 24-h average pain ratings recorded in the patient's diary. Mean changes from baseline in efficacy measures were analysed by a restricted maximum likelihood-based, mixed-effects model repeated measures approach and by analysis of covariance. RESULTS Of the 405 patients randomised, 203 patients were assigned to duloxetine 60 mg once daily and 202 patients were assigned to placebo. Duloxetine-treated patients showed significantly greater pain relief on 24-h average pain ratings compared with placebo-treated patients each week of the 12-week study period [week 12: least squares (LS) mean change duloxetine: -2.40, placebo: -1.97; LS mean change difference (95% confidence interval) = -0.43 (-0.82, -0.04), p = 0.030]. Compared with placebo, patients treated with duloxetine experienced higher rates of nausea (p = 0.010), somnolence (p < 0.001) and asthenia (p = 0.002). CONCLUSIONS Duloxetine-treated patients showed significantly greater pain relief compared with placebo-treated patients over the 12-week study period. Duloxetine was shown in Chinese patients to have a safety profile similar to that found in previous duloxetine trials.

Abstract
OBJECTIVE To investigate the clinical significance of mild hypothermia therapy in patients with resuscitation of cardiac arrest and analyze the possible molecular mechanism. PATIENTS AND METHODS Ninety-six patients with successful resuscitation of cardiac arrest in ICU were hospitalized from June 2009 to July 2014. They were divided into a control group (n=37 cases) and an observation group (n=59 cases). All patients received high-grade life support treatment immediately after resuscitation. The treatment for the control group was combined with normal temperature treatment while the treatment for the observation group was combined with mild hypothermia therapy. RESULTS 1. Glasgow coma scale (GCS) scores of the patients in the two groups increased gradually after treatment as the APACHE II scores decreased. Comparisons within the group showed significant differences (p < 0.05). The GCS scores of the observation group were significantly increased compared to those in the control group, and the APACHE score decreased significantly. The differences between the groups were statistically significant (p < 0.05). 2. The serum lactic acid, sCD14, S100 β protein and TNF-a level of patients in two groups all decreased after treatment. The difference was statistically significant (p < 0.05 =. 3. The 24h and 7d survival rates of patients in the observation group are higher than that in the control group (p < 0.05). CONCLUSIONS The early treatment of hypothermia, can improve the outcome of patients with cardiac arrest.

Abstract
AIMS The prevalence of subclinical hypothyroidism (SCH) is high among patients with diabetes, although the relationship between SCH and diabetic vascular complications is unknown. This study aimed to determine the relationship between SCH and vascular complications in patients with Type 2 diabetes. METHODS In this cross sectional study, 991 patients with Type 2 diabetes were screened for thyroid function at their admission to the Second Affiliated Hospital of Chongqing Medical University. We compared the prevalence of coronary heart disease (CHD), ischaemic stroke and chronic kidney disease (CKD) with the prevalence of euthyroidism and SCH. RESULTS Among the 991 patients, 126 (12.7%) patients had SCH. The prevalence of CHD was significantly higher in the SCH group than in the euthyroid group (22.2% and 15.0%, respectively; P = 0.039). In the logistic regression analyses, SCH was associated with CHD [odds ratio (OR): 1.993; 95% confidence interval (CI): 1.135-3.497; P = 0.016]. This association was stronger in patients aged ≥ 65 years than in younger patients [2.474 (1.173-5.220); P = 0.017]. No significant association was found between SCH and ischaemic stroke. Patients with severe SCH had a high risk of CKD [1.842 (1.120-3.029); P = 0.016]. CONCLUSIONS This study provides evidence that SCH in patients with Type 2 diabetes is associated with a high prevalence of CHD (and CKD in severe SCH), although not with ischaemic stroke.

Abstract
Toll-like receptors (TLRs), the triggers of the innate and adaptive immune responses, are involved in the pathogenesis of type 2 diabetes mellitus (T2DM). Several studies have investigated the effects of genetic polymorphisms in TLR4 and TLR2, but they have yielded limited results. We investigated whether non-missense genetic polymorphisms in the regulatory regions of TLR4 and TLR2 were related to T2DM in a southern Chinese population. Single nucleotide polymorphisms (SNPs) in TLR4 (rs1927911, rs11536889, rs1927907, rs1927906, rs1927914, rs7873784, and rs2149356) and TLR2 (rs1898830, rs3804099, rs4696480, and rs3804100) were genotyped in 552 T2DM and 552 unrelated age- and gender-matched controls by SNaPShot Multiplex assay. Genotypes GG (OR = 0.09, 95%CI = 0.01- 0.83, P = 0.03) and CG (OR = 0.08, 95%CI = 0.01-0.74, P = 0.03) of the 3'-untranslated region (UTR) SNP rs7873784 in TLR4, and genotype AG (OR = 0.67, 95%CI = 0.46-0.97, P = 0.04) and allele G (OR = 0.88, 95%CI = 0.79-0.97, P = 0.01) of the intron SNP rs1898830 in TLR2 were identified as protective against the development of T2DM in southern Chinese people. In contrast, a meta-analysis of rs1927911 and rs1927914 showed no association. Haplotypes AGTT (OR = 0.34, 95%CI = 0.15-0.77, P = 0.01) and AATT (OR = 1.20, 95%CI = 1.01- 1.44, P = 0.05) in TLR2 were significantly associated with susceptibility to T2DM. Our results suggest that the effects of non-missense polymorphisms located in the regulatory regions of TLR4 and TLR2 should not be neglected in T2DM association analysis.

Abstract
Bruton's tyrosine kinase (BTK) kinase is a member of the TEC kinase family and is a key regulator of the B-cell receptor (BCR)-mediated signaling pathway. It is important for B-cell maturation, proliferation, survival and metastasis. Pharmacological inhibition of BTK is clinically effective against a variety of B-cell malignances, such as mantle cell lymphoma, chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML) and activated B-cell-diffuse large B-cell lymphoma. MNK kinase is one of the key downstream regulators in the RAF-MEK-ERK signaling pathway and controls protein synthesis via regulating the activity of eIF4E. Inhibition of MNK activity has been observed to moderately inhibit the proliferation of AML cells. Through a structure-based drug-design approach, we have discovered a selective and potent BTK/MNK dual kinase inhibitor (QL-X-138), which exhibits covalent binding to BTK and noncovalent binding to MNK. Compared with the BTK kinase inhibitor (PCI-32765) and the MNK kinase inhibitor (cercosporamide), QL-X-138 enhanced the antiproliferative efficacies in vitro against a variety of B-cell cancer cell lines, as well as AML and CLL primary patient cells, which respond moderately to BTK inhibitor in vitro. The agent can effectively arrest the growth of lymphoma and leukemia cells at the G0-G1 stage and can induce strong apoptotic cell death. These primary results demonstrate that simultaneous inhibition of BTK and MNK kinase activity might be a new therapeutic strategy for B-cell malignances.

Abstract
We developed a robust and low-cost array of virtual Frisch-grid CdZnTe detectors coupled to a front-end readout application-specific integrated circuit (ASIC) for spectroscopy and imaging of gamma rays. The array operates as a self-reliant detector module. It is comprised of 36 close-packed 6 × 6 × 15 mm(3) detectors grouped into 3 × 3 sub-arrays of 2 × 2 detectors with the common cathodes. The front-end analog ASIC accommodates up to 36 anode and 9 cathode inputs. Several detector modules can be integrated into a single- or multi-layer unit operating as a Compton or a coded-aperture camera. We present the results from testing two fully assembled modules and readout electronics. The further enhancement of the arrays' performance and reduction of their cost are possible by using position-sensitive virtual Frisch-grid detectors, which allow for accurate corrections of the response of material non-uniformities caused by crystal defects.

Abstract
The activation of cancer-associated fibroblasts (CAFs) is a key event in tumor progression, and alternative extracellular matrix (ECM) proteins derived from CAFs induce ECM remodeling and cancer cell invasion. Here we found that miR-200 s, which are generally downregulated in activated CAFs in breast cancer tissues and in normal fibroblasts (NFs) activated by breast cancer cells, are direct mediators of NF reprogramming into CAFs and of ECM remodeling. NFs with downregulated miR-200 s displayed the traits of activated CAFs, including accelerated migration and invasion. Ectopic expression of miR-200 s in CAFs at least partially restored the phenotypes of NFs. CAF activation may be governed by the targets of miR-200 s, Fli-1 and TCF12, which are responsible for cell development and differentiation; Fli-1 and TCF12 were obviously elevated in CAFs. Furthermore, miR-200 s and their targets influenced collagen contraction by CAFs. The upregulation of fibronectin and lysyl oxidase directly by miR-200 or indirectly through Fli-1 or TCF12 contributed to ECM remodeling, triggering the invasion and metastasis of breast cancer cells both in vitro and vivo. Thus, these data provide important and novel insights into breast CAF activation and ECM remodeling, which trigger tumor cell invasion.

Abstract
Recent studies have suggested that contactin-1 has a key role in cancer cell proliferation and migration, however the detailed mechanism of this process is still unclear. Here, human gastric cancer cell line MKN45 was employed. It was found that under hypoxia conditions contactin-1 mRNA and protein levels were both up-regulated by HIF-1alpha expression. Furthermore, although hypoxia increased the migration rate of MKN45 cells, contactin-1 (CNTN1) shRNA reversed this process. Meanwhile, RhoA V14 and RhoA V14N19 mutation constructs were employed, and it was found that constitutively active form of RhoA reversed the cell migration suppression induced by contactin-1 knockdown, while dominant-negative form of RhoA blocked hypoxia induced hypermigration. Apart from this, contactin-1 displayed the ability to phosphorylate the RhoA activator p115 RhoGEF. Thus, under hypoxia conditions, elevated HIF-1alpha seems to up-regulate contactin-1 expression and by this activate RhoA and facilitate migration of cancer cells.

Abstract
DNA fingerprinting is both a popular and important technique with several advantages in plant cultivar identification. However, this technique has not been used widely and efficiently in practical plant identification because the analysis and recording of data generated from fingerprinting and genotyping are tedious and difficult. We developed a novel approach known as a cultivar identification diagram (CID) strategy that uses DNA markers to separate plant individuals in a more efficient, practical, and referable manner. A CID was manually constructed and a polymorphic marker was generated from each polymerase chain reaction for sample separation. In this study, 67 important sea buckthorn cultivars cultivated in China were successfully separated with random amplified polymorphic DNA markers using the CID analysis strategy, with only seven 11-nucleotide primers employed. The utilization of the CID of these 67 sea buckthorn cultivars was verified by identifying 2 randomly chosen groups of cultivars among the 67 cultivars. The main advantages of this identification strategy include fewer primers used and separation of all cultivars using the corresponding primers. This sea buckthorn CID was able to separate any sea buckthorn cultivars among the 67 studied, which is useful for sea buckthorn cultivar identification, cultivar-right-protection, and for the sea buckthorn nursery industry in China.

Abstract
The epithelial-mesenchymal transition (EMT) is a critical process in the pulmonary fibrosis. It has been reported that bone morphogenetic protein 7 (BMP-7) was able to reverse EMT in proximal tubular cells. Therefore, we test the hypothesis that EMT contributes to silica-induced pulmonary fibrosis and BMP-7 inhibits EMT in silica-induced pulmonary fibrosis. Progressive silica-induced pulmonary fibrosis in the rat was used as a model of silicosis. Epithelial and mesenchymal markers were measured from rat fibrotic lungs. Then the effects of BMP-7 on the EMT were further confirmed in A549 cells. There are increases of vimentin as a mesenchymal marker and decreases of E-cadherin as an epithelial marker in the silica-exposed rat lungs, which is in agreement with the A549 cells data. However, BMP-7 treatment significantly reduced expression of vimentin in the rat pulmonary fibrosis model and in A549 cells. In conclusion, EMT contributes to silica-induced pulmonary fibrosis. Meanwhile, the treatment of BMP-7 can inhibit silica-induced EMT in vitro and in vivo.

Abstract
This pilot study assesses the safety and efficacy of once-daily, oral levofloxacin monotherapy in Chinese patients with low-risk febrile neutropenia. In this prospective, single-arm, open-label, multicenter clinical trial, 46 adult Chinese patients with solid tumors and low-risk febrile neutropenia were included. Patients received oral levofloxacin monotherapy (500 mg orally/day) until day 12, followed by 7 days of follow-up (day 19). Body temperature was measured three times per day. On days 2, 3, 5-7, 9, 12, and 19, disease symptoms and vital signs were recorded, adverse drug reactions were assessed, and blood samples were collected to determine the whole-blood cell count and the absolute neutrophil count. Blood cultures and chest radiographs were performed simultaneously until negative results were found. Oral levofloxacin was effective and well tolerated in 97.6% of patients irrespective of the cancer type and cause of fever. Body temperature began to decline in 24.4, 68.3, and 90.2% of patients, respectively, at 12, 24, and 48 h after initiating levofloxacin therapy. On days 5 and 7, 95.1 and 97.6% of the patients had complete defervescence, respectively. The median time for absolute neutrophil count recovery to at least 1500/mm after initiation of treatment was 3 days. Only one patient reported mild diarrhea. This pilot study showed that oral levofloxacin quickly and effectively reduced fever, initiated neutrophil recovery, and was well tolerated in Chinese low-risk febrile neutropenic patients with solid tumors. Further study is needed to compare patient data of levofloxacin with the standard amoxicillin/ciprofloxacin protocol in this population for both safety and efficacy.

Abstract
AIMS To evaluate the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in Asian patients with type 2 diabetes mellitus (T2DM) inadequately controlled by metformin or metformin in combination with sulphonylurea. METHODS In this 18-week, randomized, double-blind, placebo-controlled phase III study, patients (N = 676) received canagliflozin 100 or 300 mg or placebo once daily. The primary efficacy endpoint was change in glycated haemoglobin (HbA1c) level from baseline at week 18. Additional endpoints included change in fasting plasma glucose (FPG) and percent change in body weight. Adverse events (AEs) were recorded throughout the study. Efficacy and safety were assessed in the overall population and in two strata based on background therapy. RESULTS At week 18, canagliflozin 100 and 300 mg provided significant reductions from baseline in HbA1c compared with placebo (-0.97, -1.06 and -0.47%, respectively; p < 0.001). Relative to placebo, canagliflozin 100 and 300 mg also significantly reduced FPG (-1.0 and -1.4 mmol/l) and body weight [-2.2% (-1.5 kg) and -2.3% (-1.6 kg)]. Both canagliflozin doses lowered systolic blood pressure (BP) compared with placebo. The overall incidence of AEs was 38.6, 43.2 and 42.0% with canagliflozin 100 and 300 mg and placebo, respectively. The incidence of genital mycotic infections and urinary tract infections was low and similar across groups. Efficacy and safety findings in the two strata were generally consistent with the overall population. CONCLUSIONS Canagliflozin provided glycaemic improvements and reductions in body weight and systolic BP, and was generally well tolerated in Asian patients with T2DM on metformin or metformin in combination with sulphonylurea.

Abstract
UNLABELLED Fibroblast growth factor 23(FGF23) is a bone-derived hormone which regulates mineral homeostasis but may also have a role in cardiovascular disease. Here, we found that higher plasma FGF23 was independently associated with decreased heart rate variability in stage 5 CKD patients and parathyroidectomy may reverse these abnormal indicators. INTRODUCTION Lower heart rate variability (HRV) in patients with chronic kidney disease (CKD) compared with healthy controls is associated with increased risk of cardiovascular disease (CVD). Higher levels of plasma FGF23 also predict higher risk of CVD. Here, we aimed to evaluate the relationship between plasma FGF23 levels and HRV in patients with stage 5 CKD and to investigate longitudinal changes of them together with the correlation between their changes in two severe secondary hyperparathyroidism (SHPT) subgroups with successful parathyroidectomy (PTX) and persistent SHPT. METHODS This cross-sectional study included 100 stage 5 CKD patients, 78 controls, and a prospective study in two PTX subgroups classified as successful PTX (n = 24) and persistent SHPT (n = 4) follow-up. Blood examination and 24-h Holter monitoring for HRV were measured. RESULTS Most HRV indices were lower in stage 5 CKD patients than in healthy controls, and plasma FGF23 levels were higher. In multivariate stepwise regression models, levels of plasma FGF23 and serum parathyroid hormone (PTH) were correlated with HRV. The successful PTX subgroup had significant improvements over baseline in HRV indices. Persistent SHPT subgroup had numerically similar changes in HRV indices. However, plasma FGF23 levels decreased in both subgroups. CONCLUSIONS Plasma FGF23 levels were higher in CKD patients than in controls, much higher in patients with severe SHPT. FGF23 was independently associated with decreased HRV in stage 5 CKD. Successful PTX may reverse these abnormal indicators and contribute to decreases in the risk of cardiovascular disease.

Abstract
RNA-mediated virus resistance based on natural antiviral RNA silencing has been exploited as a powerful tool for engineering virus resistance in plants. In this study, a conserved 3'-region (positions 9839-10117, 279 nt) of the capsid protein (CP) gene of papaya ringspot virus (PRSV), designated CP279, was used to generate an intron-containing hairpin RNA (ihpRNA) construct by one-step, zero-background ligation-independent cloning (OZ-LIC). The RNaseIII-deficient Escherichia coli strain M-JM109lacY was identified as the best choice for producing large quantities of specific ihpRNA-CP279. Resistance analyses and ELISA data verified that most papaya plants mechanically co-inoculated with TRIzol-extracted ihpRNA-CP279 and PRSV were resistant to PRSV, and resistance was maintained throughout the test period (>2 months post-inoculation). In contrast, a 1-2 day interval between sequential inoculation of PRSV and ihpRNA-CP279 did not result in complete protection against PRSV infection, but delayed the appearance of viral symptoms by 3 to 4 days. These findings indicate that direct mechanical inoculation of papaya plants with bacterially-expressed ihpRNA-CP279 targeting the PRSV CP gene can interfere with virus infection. This work lays a foundation for developing a non-transgenic approach to control PRSV by directly spraying plants with ihpRNA or crude bacterial extract preparations.

Abstract
BACKGROUND AND AIMS Stroke is often accompanied by hyperglycaemia, and this has an important impact on prognosis. The aim of this study was to investigate the relationship between early hyperglycaemia and the outcome of spontaneous intracerebral haemorrhage (sICH). METHODS A systematic literature search on PubMed, Embase, Cochran, WANFANG DATA, VIP and CNKI databases was conducted, and eight eligible studies were retrieved. Relative risks and 95% confidence interval (CI) in the hyperglycaemia group compared with the non-hyperglycaemia group were calculated and meta-analysed when possible. RESULTS Eight controlled trials and cohort studies totalling 3756 patients addressing early hyperglycaemia and the outcome of sICH were compiled for this meta-analysis. Cut-off points for defining hyperglycaemia was 6.1-8.3 mmol/L, and the median cut-off value was 7.5 mmol/L. Studies were assigned to one of the two subgroups: the group A (for studies with the values of glucose concentrations above the median cut-off) and the group B (for studies with the values of glucose concentrations below the median cut-off). The RR for short-term death associated with hyperglycaemia was 3.65 (95% confidence interval (CI) (3.08, 4.33); P < 0.0001). In the subgroup analysis, the relative risk values were 3.46 (95% CI (1.66, 7.20); P = 0.0009) and 3.53 (95% CI (2.92, 4.26); P < 0.00001) for the groups A and B respectively. The publication bias showed that Egger's test (P > 0.1), Begg's test (P > 0.05) and Nfs0.05 exceeded included studies. CONCLUSIONS Early hyperglycaemia can significantly increase the rate of early-term death in patients with sICH, independent of the cut-off points for hyperglycaemia.

Abstract
The reliability of comprehensive intra-oral quantitative sensory testing (QST) protocol has not been examined systematically in patients with chronic oro-facial pain. The aim of the present multicentre study was to examine test-retest and interexaminer reliability of intra-oral QST measures in terms of absolute values and z-scores as well as within-session coefficients of variation (CV) values in patients with atypical odontalgia (AO) and healthy pain-free controls. Forty-five patients with AO and 68 healthy controls were subjected to bilateral intra-oral gingival QST and unilateral extratrigeminal QST (thenar) on three occasions (twice on 1 day by two different examiners and once approximately 1 week later by one of the examiners). Intra-class correlation coefficients and kappa values for interexaminer and test-retest reliability were computed. Most of the standardised intra-oral QST measures showed fair to excellent interexaminer (9-12 of 13 measures) and test-retest (7-11 of 13 measures) reliability. Furthermore, no robust differences in reliability measures or within-session variability (CV) were detected between patients with AO and the healthy reference group. These reliability results in chronic orofacial pain patients support earlier suggestions based on data from healthy subjects that intra-oral QST is sufficiently reliable for use as a part of a comprehensive evaluation of patients with somatosensory disturbances or neuropathic pain in the trigeminal region.

Abstract
The uncoupling protein 1 (UCP1) plays an important role in the regulation of lipolysis and thermogenesis in adipose tissues. Genetic variation within three regions (the promoter, intron 2 and exon 5) of the ovine UCP1 gene (UCP1) was investigated using polymerase chain reaction-single-strand conformational polymorphism (PCR-SSCP) analyses. These revealed three promoter variants (designated A, B and C) and two intron 2 variants (a and b). The association of this genetic variation with variation in lamb carcass traits and postweaning growth was investigated in New Zealand (NZ) Romney and Suffolk sheep. The presence of B in a lamb's genotype was associated with decreased subcutaneous carcass fat depth (V-GR) (p = 0.004) and proportion of total lean meat yield of loin meat (p = 0.005), and an increased proportion of total lean meat yield of hind-leg meat (p = 0.018). In contrast, having two copies of C was associated with increased V-GR (p < 0.001) and proportion of total lean meat yield of shoulder meat (p = 0.009), and a decreased hind-leg yield (p = 0.032). No associations were found with postweaning growth. These results suggest that ovine UCP1 is a potential gene marker for carcass traits.

Abstract
INTRODUCTION The diagnosis of lymphoid malignancies is often challenging in paucicellular specimens. PCR may also be limited by insufficient cells for DNA isolation and incomplete coverage of gene rearrangements. This study aims to evaluate a PCR method for IgH clonality using direct cell lysates. METHODS PCR amplification used cell lysate from detergent-based lysis and BIOMED-2 primers. CSF specimens were tested for 20 patients with primary CNS lymphoma or systemic lymphoma suspected for CNS involvement. Cytology and flow cytometry analysis was performed in parallel with PCR. RESULTS Direct lysis produced a better yield than the column-based method for DNA isolation. PCR using lysate showed an efficiency of clonality detection from a minimum of 20 tumor cells. PCR clonality was found in nine of the 20 CSFs, and positive PCR was concordant with both cytology and flow cytometry in seven cases. There were two cases positive for PCR, but indeterminate for flow cytometry because of insufficient cell events. Of the eleven PCR-negative cases, two were considered as false negative, as flow cytometry showed positive for malignant cells. The PCR was also performed successfully with a specimen from the anterior chamber of the eye. CONCLUSION PCR clonality with direct cell lysis of CSF is feasible, and it may overcome the limitation of DNA isolation. This PCR method may be particularly useful for small volume and low cell CSF when flow cytometry is inconclusive.

Abstract
OBJECTIVES Genome-wide association studies (GWAS) have shown that Zbed3 is associated with T2DM. To date, no report has demonstrated a relationship between Zbed3 and insulin resistance in humans, however. The purpose of this study was to determine whether the Zbed3 protein is secreted and identify any associations between Zbed3 and insulin resistance in cross-sectional and interventional studies. METHODS We found that Zbed3 protein was secreted in an in vitro secretion study. Plasma Zbed3 levels were determined in an ELISA and were compared with various parameters related to insulin resistance in subjects with NGT, IGT and nT2DM. EHC was performed in healthy subjects. Real-time PCR and Western blotting were used to assess the mRNA and protein expression of Zbed3. RESULTS Zbed3 was detected in an analysis of in vitro secretion in both conditioned medium and lysates of HEK-293T cells transfected with an overexpressed vector. In a clinical study, there were significantly higher levels of circulating Zbed3 in IGT and nT2DM relative to NGT. Zbed3 levels were positively correlated with BMI, WHR, FAT%, blood pressure, FBG, TG, HbA1c, FIns and HOMA-IR and inversely correlated with HDL-C. Increasing levels of Zbed3 were independently associated with IGT and T2DM. Zbed3 mRNA and protein in muscle and fat were significantly elevated in both db/db mice and T2DM patients. Moreover, there was a concentration-dependent effect of glucose on Zbed3 release, whereas insulin exhibited an inhibitory effect on Zbed3 levels. Zbed3 suppressed insulin-induced IR and Akt phosphorylation. CONCLUSIONS These results suggest that the Zbed3 protein may be a cytokine associated with insulin resistance in humans that is influenced by glucose and insulin levels.

Abstract
SUMMARY We described six uremic leontiasis ossea (ULO) patients who underwent total parathyroidectomy with autotransplantation. ULO demonstrated more a systemic disease than a simple craniofacial deformation. The surgery seemed an effective treatment to alleviate secondary hyperparathyroidism and to improve patients' quality of life. ULO may have a high postoperative recurrence tendency. INTRODUCTION ULO is a rare disease derived from uremic secondary hyperparathyroidism (SHPT). Previous studies mostly focused on the craniofacial deformations. This study aims to investigate the systemic features of the disease and the surgical outcomes. METHODS The present study retrospectively assessed six ULO patients who underwent total parathyroidectomy (TPTX) with autotransplantation (AT). Follow-up data were recorded. The follow-up status was considered as "effectiveness" if serum intact parathyroid hormone (iPTH) levels were <150 pg/mL in the first 3 days after surgery, or as "recurrence" if serum iPTH gradually increased >300 pg/mL during follow-up in patients whose status was initially considered as "effectiveness". RESULTS Craniofacial deformations, short stature, thoracocyllosis, spine malformations, osteodynia, and muscle weakness were observed in all patients. Abnormal pulmonary functions were observed in five patients. After surgery, one patient died from respiratory failure. Surgery was effective in the remaining five patients with relieved osteodynia and stopped craniofacial deformation. A mean follow-up of 7.6 (4 to 12) months was available. Three patients suffered from recurrence of hyperparathyroidism originating from autografts. CONCLUSIONS Our data suggests that ULO is not only a simple disease with craniofacial malformations but is a severe systemic disease leading to increased surgical risks. TPTX with AT seems an effective treatment to relieve SHPT and to improve quality of life. ULO may have a high postoperative recurrence tendency.

Abstract
OBJECTIVE China is experiencing a rapid increase in cancer incidence in elderly patients. In order to better understand this group, a large study of patients from multiple tertiary centers in the Beijing area was designed. This study was designed to provide insight into their unique treatment preferences, including the use of traditional Chinese medicine (TCM). MATERIALS AND METHODS 803 patients from nine hospitals in the Beijing area were enrolled into this study. The inclusion criteria were patients who were 65 years or older and had a diagnosis of cancer at any stage. The CGA questionnaire used with these patients included the Chinese translation of the Gero-Oncology Health and Quality of Life Assessment tool. The questionnaire was provided to patients by a research nurse and was administered in Mandarin. RESULTS The mean age of the patients was 72 years (range 65-94). The patients were mainly male (59.8%) and of Han ethnicity (95.4%). About 45% of these patients also had concurrent TCM in addition to their other cancer treatments. About 70% were able to manage their activities of daily living without assistance. Patients on TCM were more likely to have higher number of co-morbidities compared to their counterparts. CONCLUSION This is the largest prospective study of CGA assessments done on elderly patients with cancer in Asia. The study demonstrates that CGA provides insights into understanding the needs of elderly Chinese patients with cancer. TCM is used frequently in China, and its impact on quality of life needs further investigation.

Abstract
BACKGROUND The aim of our study was to identify potential risk factors for anal fistula in order to improve prevention and treatment of anal fistula. METHODS A retrospective case-control study for anal fistula was conducted at our unit. Logistic regression analyses were carried out to identify associated risk factors for anal fistula. RESULTS The final model obtained by the stepwise forward logistic regression analysis method identified the following items as independent risk factors: body mass index of >25.0 kg/m(2), high daily salt intake, history of diabetes, hyperlipidemia, dermatosis, anorectal surgery, history of smoking and alcohol intake, sedentary lifestyle, excessive intake of spicy/greasy food, very infrequent participation in sports and prolonged sitting on the toilet for defecation. CONCLUSIONS Our results indicate that lifestyle factors and certain medical conditions increase an individual's risk of developing anal fistula.

Abstract
OBJECTIVES Infantile spasms (IS) are severe epileptic encephalopathy during infancy. The SCN1A encodes the α1 subunit of the neuronal voltage-gated sodium channels, and mutations in SCN1A have been frequently detected in idiopathic epilepsy and encephalopathy, which had similar symptoms as IS. Therefore, we investigated the association of SCN1A polymorphism with the IS and the responsiveness to adrenocorticotropic hormone (ACTH) treatment in the present study. PATIENTS AND METHODS We totally collected 113 IS patients and and 122 age-matched healthy controls. All of the subjects were Han Chinese descent, and the 113 cases were further divided into subgroups of cryptogenic and symptomatic patients. Nine tag SNPs within the SCN1A gene were selected and genotyped by the direct sequencing of PCR-amplified products. The ACTH was then applied to all of the cases. RESULTS Two SNPs in high linkage disequilibrium, rs13397210 and rs760543, were significantly associated with IS under genotype model (p = 0.015). In addition, we also found that a 4-SNP haplotype (CAGC) which contains the aforementioned 2 SNPs, was associated with increased responsiveness to ACTH therapy in IS (p = 0.018, OR = 4.8) under recessive model. Of the 2 subgroups of cases, more cryptogenic patients responded to the ACTH treatment than the symptomatic patients. CONCLUSIONS The results suggested that genetic variants of the SCN1A gene were associated with IS and ACTH responsiveness.
