Absence of hybridization with the wild-type and mutant rpoB probes in the Genotype MTBDRplus assay detects 'disputed' rifampicin mutations. Clin Microbiol Infect 2017; 24:781.e1-781.e3. [PMID: 29217277 DOI: 10.1016/j.cmi.2017.11.021] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2017] [Revised: 11/28/2017] [Accepted: 11/29/2017] [Indexed: 11/18/2022]
Abstract
OBJECTIVE Mycobacterium tuberculosis isolates that fail to hybridize to at least one rpoB wild-type or any mutation probe on the Genotype MTBDRplus strip are assumed to be rifampicin-resistant. However, the precise mutation(s) are unknown. We sought to identify the mutations in isolates with such hybridization patterns and determine if the mutations are associated with resistance to rifampicin. METHODS In this study, 275 M. tuberculosis isolates were screened with the Genotype MTBDRplus assay to identify isolates with the hybridization pattern. These isolates were sequenced and their minimum inhibitory concentrations (MIC) determined using the Bactec MGIT 960 system. RESULTS Among the 275 isolates tested, 15 (6%) isolates with the hybridization pattern were identified. Sequencing showed that failure to hybridize to rpoB wild-type probes resulted from the presence of 'disputed' rifampicin mutations, which are mutations not always associated with a rifampicin-resistant phenotype. All, except 3/15, isolates had a rifampicin-resistant phenotype (MIC > 1 μg/mL). One of the three isolates with a rifampicin-susceptible phenotype had the same mutation at position 526 (His526Leu) as another isolate that had a rifampicin-resistant phenotype. CONCLUSION The recommendation of the Genotype MTBDRplus assay to assume rifampicin resistance based solely on failure to hybridize to rpoB wild-type probe allows the identification of important RIF-resistant isolates. About 20% (3/15) of such isolates could be missed by relying only on the standard MGIT 960 DST assay for drug susceptibility testing.

Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy and safety of long-term treatment with Cimicifuga foetida extract in menopausal women. METHODS A prospective, randomized, controlled clinical trial was conducted. A total of 96 early postmenopausal women were randomly assigned to three groups: group A received 1 mg estradiol valerate daily plus 4 mg medroxyprogesterone acetate on days 19-30; group B received 1 mg estradiol valerate daily plus 100 mg micronized progesterone on days 19-30; group C received 100 mg C. foetida extract daily. The efficacy was evaluated. Safety parameters were recorded. RESULTS A total of 81 patients completed the treatment and follow-up visit. The modified Kupperman Menopausal Index scores decreased after 3 months in all groups. No significant changes were observed in the liver, renal function and components of metabolic syndrome in group C (p > 0.05). There were no significant differences in the incidences of metabolic syndrome among the three groups (p > 0.05). After 24 months, the endometrial thickness increased significantly in group B (p = 0.014), but not in the C. foetida extract group (p > 0.05). CONCLUSIONS C. foetida extract is safe and effective for the treatment of menopausal symptoms in postmenopausal women.

Abstract
Objective: To understand the probability of premature mortality caused by non-communicable diseases (NCD) in Beijing from 2010 to 2015. Methods: The data of deaths from Beijing vital registration system were used to analyze age-standardized NCD mortality rates, proportion of NCD deaths in age group <70 years and premature NCD mortality. Results: NCD deaths accounted for 90% of the total deaths in Beijing. Age-standardized NCD death rate decreased from 332.43/100 000 in 2010 to 280.02/100 000 in 2015. Meanwhile, the probability of deaths from four NCDs between in age group 30-70 years (premature NCD mortality) decreased from 12.81% to 11.11% in Beijing. The premature mortality of four NCDs in men was 14.63%, and compared with 2015 baseline, it would decrease by 16.4% to reach 2025 goal (12.23%), and the probability of premature mortality four NCDs in women was 7.54%, and compared with 2015 baseline, it would decrease by 6.8% to reach the 2025 goal (7.03%). People living in suburb areas had a higher probability of premature NCD mortality (13.67%) than those living in urban areas (9.72%) in Beijing in 2015. Conclusions: The premature NCD mortality was much higher in men than in women in Beijing. More attention should be paid to the control of risk factors for NCD premature deaths, especially in men and in suburb residents, to reach the 25×25 goal.

Abstract
The DNA methylation of imprinted genes is an important way to regulate epigenetic reprogramming of donor cells in somatic cell nuclear transfer (SCNT). However, the effects of sexual distinction on the DNA methylation of imprinted genes in cloned animals have seldom been reported. In this study, we analysed the DNA methylation status of three imprinted genes (Xist, IGF2 and H19) from liveborn cloned buffaloes (L group, three female and three male), stillborn cloned buffaloes (S group, three female and three male) and natural reproduction buffaloes (N group, three female and three male), using bisulphite sequencing polymerase chain reaction (BS-PCR). The expression levels of these imprinted genes were also investigated by quantitative real-time PCR (QRT-PCR). The DNA methylation levels of H19 were not significantly different among the groups. However, the Xist in female and IGF2 in male of the S group were found to be significantly hypomethylated in comparison with the same sexual buffaloes in L group and N group (p < .05). Furthermore, the expression levels of Xist, IGF2 and H19 in the stillborn female cloned buffaloes of S group were significantly higher than that of the female buffaloes in the L group and N group (p < .05). The expression levels of IGF2 and H19 in the stillborn male cloned buffaloes in the S group were significantly higher than that of the male buffaloes in the L group and N group (p < .05). These results indicate that Xist may be associated with the viability of female cloned buffaloes, and IGF2 may also be related to the viability of male cloned buffaloes.

Abstract
The objective of this study was to evaluate the effect of residual feed intake (RFI) on rumen function in finishing lambs. A total of 60 male Hu lambs (average initial BW = 25.2 ± 2.5kg) were used and were offered a pelleted high-concentrate diet, of which the forage to concentrate ratio was 25:75. Individual feed intake was recorded over a period of 42 d, then 10 lambs with the lowest RFI and the highest RFI were selected, respectively. The rumen fluid used for fermentation variables and relative abundance of bacteria measurement was obtained on d 10 and 20 after RFI measurement. At the end of this experiment, the selected lambs were slaughtered and rumen epithelium and liver tissues were collected for RNA extraction. Low-RFI lambs had lower ( < 0.01) DMI and greater ( < 0.05) G:F than the high-RFI ones, while the RFI groups did not differ in ADG and BW ( > 0.05). Additionally, RFI was positively ( = 0.57; < 0.01) correlated with DMI and negatively ( = -0.53; < 0.05) correlated with G:F. Total VFA and individual VFA decreased ( < 0.05) over time. The concentrations of total VFA, acetate, valerate, isobutyrate, isovalerate, and rumen pH ( > 0.05) were not affected by RFI classification. Nonetheless, low-RFI group lambs had a greater ( < 0.05) concentration of propionate, a lower ( < 0.05) concentration of butyrate, and a lower ( < 0.05) acetate to propionate ratio compared with the high-RFI group. There was a significant ( < 0.05) effect of RFI on the relative abundance of and . The relative abundance of , , and decreased ( < 0.05) over time in high-RFI group. And the relative abundance of in high-RFI group was greater ( < 0.05) than its low-RFI counterpart. Furthermore, RFI had no effect ( > 0.05) on gene expression associated with intracellular pH regulation (, , , , , , , and ) in rumen epithelium and β-hydroxybutyrate metabolism () in both rumen epithelium and liver tissues. In conclusion, even though low-RFI lambs had lower DMI, however, the number of was lower. Additionally, there was no difference in gene expressions level associated with intracellular pH regulation in rumen epithelium between RFI groups.

Abstract
Heterochromatin protein 1γ (HP1γ) has been implicated in carcinogenesis of various cancer types. However, the role of HP1γ in prostate cancer (PCa) progression and the underlying molecular mechanisms remain largely unknown. We found that HP1γ is upregulated in PCa and elevated levels of HP1γ in PCa predict poor outcome. In addition, depletion of HP1γ in PCa cells not only repressed proliferation and induced apoptosis but also impaired tumorigenicity. We also found that c-Myc was capable of upregulating HP1γ by directly binding to the E-box element in the first intron of HP1γ gene, and the upregulated HP1γ, in turn, repressed the expression of miR-451a by enhancing H3K9 methylation at the promoter region of miR-451a. Furthermore, reduction of miR-451a significantly reversed HP1γ loss-induced PCa cell apoptosis, whereas miR-451a overexpression repressed cell survival by targeting and downregulating c-Myc. The association among c-Myc, HP1γ and miR-451a was further confirmed in human clinical samples. Therefore, we propose that an HP1γ/miR-451a/c-Myc regulatory circuitry exists in PCa cells and this circuit has a crucial role in PCa progression.

Abstract
Hydrogen (H) enhanced cracking was studied in Fe-3wt%Si by means of in situ electrochemical microcantilever bending test. It was clearly shown that the presence of H causes hydrogen embrittlement (HE) by triggering crack initiation and propagation at the notch where stress concentration is existing. Additionally, the effect of carbon content and the presence of a grain boundary (GB) in the cantilever were studied. It was shown that in the presence of H the effect of carbon atom on pinning the dislocations is reduced. On the other hand, the presence of a GB, while the chemical composition of material kept constant, will promote the HE. Crack initiation and propagation occur in the presence of H, while the notch blunting was observed for both single and bi-crystalline beams bent in air. Post-mortem analysis of the crack propagation path showed that a transition from transgranular fracture to intragranular fracture mechanism is highly dependent on the position of the stress concentration relative to the GB.This article is part of the themed issue 'The challenges of hydrogen and metals'.

Abstract
Objective: To explore the risk factors of pancreatic fistula after pancreatoduodenectomy and its relationship with pancreatic fibrosis. Methods: Retrospective analysis was made including 408 patients who underwent pancreaticoduodenectomy from January 2013 to December 2015 in Department of Hepatobiliary Surgery of the First Affiliated Hospital of Third Military Medical University. There were 274 males and females, aging from 14 to 82 years with an average age of 54.6 years. Postoperative pathological diagnosis: 285 cases with pancreatic ductal adenocarcinoma, 81 cases with gastrointestinal tumors, 13 cases with neuroendocrine tumors, 16 cases with inflammatory changes, 8 cases with pancreatic papillary tumors, 4 cases with serous cystadenoma, 1 case with retroperitoneal liposarcoma.Univariate analysis using pearson's χ(2) test, multivariate analysis using binary Logistic regression analysis, correlation analysis using Spearman rank correlation analysis and the predictive value of pancreatic fibrosis in pancreatic fistula after pancreaticoduodenectomy was assessed using the area under the receiver operating characteristic(ROC) curve. Results: There were 123 cases (30.1%) with postoperative pancreatic fistula among 408 patients. Univariate analysis showed that body mass index(BMI)(P=0.005), preoperative gamma-glutamyltranspeptidase content(P=0.046), pancreatic duct diameter(P=0.001), CT value of pancreatic tissue(P=0.049), operation time(P=0.037), pancreatic stiffness (intraoperative judgment)(P=0.001) and percentage of pancreatic fibrosis(P=0.034) were the prognostic factors of pancreatic fistula. Multivariate analysis showed that BMI≥25 kg/m(2), pancreatic duct diameter ≤3 mm, pancreatic tissue CT value <40 Hu, pancreatic hardness (intraoperative judgments) for the soft and pancreatic lobular fibrosis percentage ≤25% of postoperative pancreatic fistula occurrence of high-risk factor(P<0.05). Pancreatic fistula's CT value and percentage of pancreatic fibrosis were significantly lower than non-pancreatic fistula group, the difference was statistically significant(P<0.05). There were significant differences in CT value and pancreatic lobular fibrosis among different grades of pancreatic fistulae(P<0.05). Pancreatic fistula severity was negatively correlated with the CT value of pancreatic body and the percentage of fibrosis of the pancreas(P=0.005, 0.019), and there was a significant correlation between CT value of pancreatic body and the percentage of fibrosis of the pancreas(r=0.699, P=0.028). The areas under the ROC curve of percentage of pancreatic fibrosis and CT value of the pancreatic body were 0.745 and 0.714, respectively. Both of them were moderate predictive value for pancreatic fistula after pancreaticoduodenectomy. Conclusions: The degree of pancreatic fibrosis is a prognostic factor for pancreatic texture and pancreatic fistula after pancreaticoduodenectomy. CT value of pancreatic body can be used as a quantitative index of pancreatic fibrosis, and predict the prognostic of pancreatic fistula after pancreaticoduodenectomy.

Exfoliation of two-dimensional phosphorene from bulk black phosphorous through chemical means is demonstrated where the solvent system of choice (choline chloride urea diluted with ethanol) has the ability to successfully exfoliate large-area multi-layer phosphorene sheets and further protect the flakes from ambient degradation. The intercalant solvent molecules, aided by low-powered sonication, diffuse between the layers of the bulk black phosphorus, allowing for the exfoliation of the multi-layer phosphorene through breaking of the interlayer van der Waals bonds. Through viscosity tuning, the optimal parameters (1:1 ratio between the intercalant and the diluting solvent) at which the exfoliation takes place is determined. Our exfoliation technique is shown to produce multi-layer phosphorene flakes with surface areas greater than 3 μm2 (a factor of three larger than what has previously been reported for a similar exfoliation method) while limiting exposure to the ambient environment, thereby protecting the flakes from degradation. Characterization techniques such as optical microscopy, Raman spectroscopy, ultraviolet-visible spectroscopy, and (scanning) transmission electron microscopy are used to investigate the quality, quantity, and thickness of the exfoliated flakes.

Abstract
Objective: To investigate the variation of electroencephalograph(EEG) power density during different sleep stages in OSA for understanding of the mechanisms underlying the brain dysfunction in OSA as well as its earlier diagnosis and treatment. Methods: Sixteen-channel EEGs from OSA patients and normal controls in stage wake, sleep stage 1, sleep stage 2, sleep stage 3 and rapid eye movement stage were analyzed by time-frequency analysis method. The EEG power density in different frequency bands (including δ, θ, α, σ, β and γ) was respectively compared between the 2 groups. The correlation between the variation in the EEG power and primary indices of polysomnography was further analyzed. Results: The EEG power density in δ band in stage wake [OSA: (0.82±0.13) μV(2)/Hz, Control: (0.66±0.02) μV(2)/Hz, t=4.309, P<0.05], stage 1 [OSA: (1.28±0.07) μV(2)/Hz, Control: (0.92±0.04) μV(2)/Hz, t=-3.369, P<0.05] and stage 3 [OSA: (2.74±0.22) μV(2)/Hz, Control: (2.04±0.07) μV(2)/Hz, t=-2.669, P<0.05] was significantly higher in OSA, compared with that in the control. Statistical analysis showed that the EEG power density was significantly higher in frontal and central regions in stage wake [frontal: OSA: (0.90±0.02) μV(2)/Hz, Control: (0.66±0.02) μV(2)/Hz, t=8.539, P<0.01; central: OSA: (1.15±0.06) μV(2)/Hz, Control: (0.72±0.02) μV(2)/Hz, t=6.669, P<0.01] and stage 1 [frontal: OSA: (1.23±0.03) μV(2)/Hz, Control: (0.99±0.03) μV(2)/Hz, t=5.983, P<0.01; central: OSA: (1.52±0.05) μV(2)/Hz, Control: (1.14±0.04) μV(2)/Hz, t=5.714, P<0.01], as well as central region in stage 3 [OSA: (3.24±0.17) μV(2)/Hz, Control: (2.71±0.08) μV(2)/Hz, t=2.707, P<0.05]. The correlation analysis showed that the power density in central region in stage 1 and stage 3 was positively correlated with arousal index (r=0.877 in stage 1, 0.656 in stage 3), implying that sleep fragmentation was closely related to the variation of EEG power density during nocturnal sleep in OSA. Conclusions: The feature stages for OSA are stage wake, stage 1 and stage 3. The EEG power density in OSA (δ band) was significantly higher than that in the control. The EEG power density in OSA and the control shows differences in frontal and central regions in stage wake and stage 1, as well as in central region in stage 3. The results indicate that low-frequency EEG power density giving priority to frontal area and central area has improved in severe OSA, which may be related to the neurologic deficits in corresponding brain areas.

Abstract
In this study, anti-hepatitis B virus (HBV) immunity was evaluated in mice using several regimens of the HBV recombinant protein vaccine HBSS1 that expressed in CHO cells containing S (1-223 aa) and preS1 (21-47 aa) and recombinant adenovirus rAdSS1 vaccine. Further, the protective efficacy of these vaccine regimens was studied in a mouse model. High titres of antigen-specific antibodies and neutralizing activity were elicited in mice after vaccination. However, robust multi-antigen (preS1 and S)-specific cell-mediated immunity (CMI) was only detected in mice primed with HBSS1 and boosted with rAdSS1. Moreover, functional T-cell responses with high levels of cytokines and antigen-specific cytotoxic T-cell responses (CD107a+ CD8+ ) were also detected in the mice. Rapid clearance of hepatitis B surface antigen and HBV DNA in blood and significantly decreased hepatitis B envelope antigen levels were observed in mice immunized with the heterogeneous prime-boost vaccine after hepatitis B virus challenge by hydrodynamic injection (HI) of pCS-HBV1.3. The clearance of HBV correlated well with antigen-specific CMI (Th1 and CTL responses) and cytokine profiles (IFN-γ, TNF-α, IL-2) elicited by vaccination. Taken together, our results might contribute to the development of new human HBV vaccines and a better understanding of the mechanisms underlying immune protection and clearance of hepatitis B virus infection.

Abstract
UNLABELLED WHAT IS KNOWN ON THE SUBJECT?: Studies show that psychological capital (PsyCap) is a protective factor against psychological distress, such as depressive symptoms. However, few have attempted to address the role of coping styles in the relationship between PsyCap and psychological distress. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: Our study found moderate levels of PsyCap among nurses in China. Among the subcategories of PsyCap, optimism and hope were most highly correlated with psychological distress. Psychological distress was positively associated with negative coping and negatively associated with positive coping. This study confirmed the partial mediating effect of coping styles in PsyCap and psychological distress among Chinese nurses. In other words, this study found direct and indirect effects of PsyCap on psychological distress mediated via coping styles. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The significant mediating effect of negative and positive coping styles between PsyCap and psychological distress has implications for hospital administrators, especially nurse leaders. Effective strategies should be implemented to improve PsyCap and coping styles among Chinese nurses, and alleviate psychological distress. Optimism and hope should be emphasized in PsyCap investment. Different styles of coping are influenced and modified by teaching and experience. Therefore, it is essential that nurse managers organize educational and training programmes to provide nurses with relative coping knowledge and techniques, and improve their coping ability. Several studies suggest that coping styles are affected by social support. Thus, nurse managers should assist nurses with social support and enhance coping strategies to reduce psychological distress. ABSTRACT Introduction PsyCap includes four categories namely self-efficacy, hope, optimism and resilience. Research has demonstrated that PsyCap and coping styles affect current psychological distress. Nevertheless, few studies have explored the role of coping styles in PsyCap and psychological distress. Aim This study investigated the role of coping styles as a mediator in PsyCap and psychological distress among Chinese nurses. Methods Participants included 538 nurses who completed self-report questionnaires assessing PsyCap, coping styles and psychological distress. Linear regression analyses were used to explore the role of coping styles. Results PsyCap, coping styles and psychological distress were significantly correlated. Among the subcategories of PsyCap, optimism and hope were most highly correlated with psychological distress. Coping styles is a partial mediator of PsyCap and psychological distress. Implications for mental health nursing The significant role of negative and positive coping styles in PsyCap and psychological distress has implications for hospital administrators, especially nurse leaders. Effective strategies should be implemented to improve PsyCap and coping styles among Chinese nurses, to alleviate psychological distress. Optimism and hope should be the focus of the improvement. Different styles of coping are developed from education and experience. Therefore, it is necessary for nurse managers to organize educational and training programmes to improve coping skills among nurses. Studies suggest that coping styles are affected by social support. Thus, nurse managers should also assist nurses with social support and enhance coping strategies to reduce psychological distress.

Abstract
OBJECTIVE To investigate the effects of early rehabilitation training after total knee arthroplasty surgery by continuous femoral nerve block (CFNB) with or without periarticular local infiltration analgesia (PLIA). METHODS In this randomized, double-blind, controlled study, 100 patients under-going primary unilateral total knee arthroplasty in patients with knee osteoarthritis were enrolled. All the patients received CFNB for postoperative analgesia before combined spinal epidural anesthesia. They were randomly divided into 2 groups (n=50 each): CFNB group, CFNB combined with PLIA group (PLIA group). Group PLIA received periarticular local infiltration analgesia with 20 mL ropivacaine (5 g/L), while the equal volume of normal saline was used instead of ropivacaine in group CFNB. Postoperative pain during rest and passive exercises including front and rear portions of knees, the time of ability to perform an active straight leg raise, the time of ability to reach 90° knee flexion, and preoperative and postoperative hospital for special surgery knee score (HSS) were evaluated. RESULTS Compared with group CFNB, the visual analogue scores (VAS) of front of knees at rest time in group PLIA had no significant difference (P>0.05); there were significant differences at 4, 8, 12, 24 h postoperation in portions of knees at rest time (P<0.05); the VAS had significant differences at 24 h in passive exercises of knees (P<0.05); the VAS had significant differences at 12, 24 h in portions of knees at passive exercises of the knees (P<0.05); the time of ability to perform an active straight leg raise had significant differences in the two groups (P<0.05). CONCLUSION Compared with CFNB postoperative analgesia alone, CFNB with PLIA could relieve rest pain and pain during passive movement after total knee arthroplasty. CFNB with PLIA could shorten the time to perform an active straight leg raise and the time of ability to reach 90° knee flexion. And so some patients could improve postoperative rehabilitation training.

Abstract
The inhibitor of apoptosis (IAP) proteins have pivotal roles in cell proliferation and differentiation, and antagonizing IAPs in certain cancer cell lines results in induction of cell death. A variety of IAP antagonist compounds targeting the baculovirus IAP protein repeat 3 (BIR3) domain of cIAP1have advanced into clinical trials. Here we sought to compare and contrast the biochemical activities of selected monovalent and bivalent IAP antagonists with the intent of identifying functional differences between these two classes of IAP antagonist drug candidates. The anti-cellular IAP1 (cIAP1) and pro-apoptotic activities of monovalent IAP antagonists were increased by using a single covalent bond to combine the monovalent moieties at the P4 position. In addition, regardless of drug concentration, treatment with monovalent compounds resulted in consistently higher levels of residual cIAP1 compared with that seen following bivalent compound treatment. We found that the remaining residual cIAP1 following monovalent compound treatment was predominantly tumor necrosis factor (TNF) receptor-associated factor 2 (TRAF2)-associated cIAP1. As a consequence, bivalent compounds were more effective at inhibiting TNF-induced activation of p65/NF-κB compared with monovalent compounds. Moreover, extension of the linker chain at the P4 position of bivalent compounds resulted in a decreased ability to degrade TRAF2-associated cIAP1 in a manner similar to monovalent compounds. This result implied that specific bivalent IAP antagonists but not monovalent compounds were capable of inducing formation of a cIAP1 E3 ubiquitin ligase complex with the capacity to effectively degrade TRAF2-associated cIAP1. These results further suggested that only certain bivalent IAP antagonists are preferred for the targeting of TNF-dependent signaling for the treatment of cancer or infectious diseases.

Abstract
Previous studies have reported the adverse cognitive effects of high folate status in older individuals with vitamin B12 (VB12) deficiency. Thus, the aim of this study was to investigate how high serum folate and VB12 deficiency could collaboratively aggravate neuronal degeneration. In total, 146 older non-demented diabetic individuals with an average age of 75 ± 3.9 were recruited. VB12 deficiency and high folate status were based on high serum methylmalonic acid (MMA) concentrations (> 0.3 μmol/L) and the serum folate concentration being in the top tertile (> 31.4 nmol/L) respectively. Among these subjects, there were 20 with elevated MMA and high folate. The structural magnetic resonance imaging data of these subjects were analyzed by performing flexible factorial analysis with the "folate level" and "MMA level" added as main effects, and the interaction effect of folate and VB12 on brain volume was evaluated. The results showed significant gray matter atrophy of the right middle occipital gyrus and the opercular part of the inferior frontal gyrus in subjects with a simultaneous high folate status and VB12 deficiency. Together with previous observational studies on cognitive function, this study lends support to the notion that high serum folate concentrations in older people with VB12 deficiency may be associated with increased neurodegeneration.

Abstract
BACKGROUND Functional bowel disorders (FBDs) such as irritable bowel syndrome (IBS) impact on quality of life and health care resources. It is uncertain whether patients with functional digestive symptoms have similar characteristics in different populations. This population-based study assessed the prevalence and identified risk factors for these disorders in South-East China. METHODS Five communities were selected at random and invitations distributed to a representative sample (block randomization). Questionnaires were completely supervised by investigators. Demographic and medical data with FBD symptoms (Rome III criteria), psychological condition, life event stress, and quality of life were collected. KEY RESULTS Functional bowel disorder prevalence was 41.6% in 1999/2115 (94.5%) completed questionnaires: 9.9% functional constipation (FC), 6.8% bloating (FB), 6.5% diarrhea (FD), 5.9% IBS (IBS-D 47.1%, IBS-M 23.9%, IBS-C 12.8%, IBS-U 16.2%), and 12.6% unspecified. Similar numbers of men and women had FBDs or IBS (overall; 51.3% male vs 48.7% female, P=.796); however, there was female predominance in FC (62.1%, P<.001) and FB (58.5%, P=.038). FBDs were associated with greater anxiety, depression, life event stress, and a lower quality of life compared with those without symptoms (all, P<.0001). Logistic regression identified medical co-morbidity, anxiety/depression, and life event stress as independent risk factors for these disorders. CONCLUSIONS & INFERENCES Functional bowel disorders are as common in South China as in western populations. A similar number of men and women report FBDs and IBS. Only FC and FB are more prevalent in females. Independent risk factors associated with FBDs included physical and psychosocial stressors.

Abstract
Objective: To investigate the feasibility of the remote control endovascular robotic system in interventional angiography. Method: The endovascular robotic system Heifetz™ and the matched steerable catheter Mirage™ were used to cannulate all the target vessels in the vascular model and cerebral arteries originated from the aorta of Bama mini-pigs under fluoroscopic guidance. The technical success rate, cannulation time and exposure dose were all collected and compared with the result of using conventional techniques. Result: All the target vessels were successfully cannulated.The average cannulation time for the steerable catheter into left subclavian artery, left common carotid artery, brachiocephalic artery, right common carotid artery and right subclavian artery in the vascular model was (21.3±2.8)s, (28.8±5.2)s, (17.7±2.6)s, (31.5±5.1)s and (24.2±3.7) s, respectively, while the average exposure dose was (9.3±1.2)mGy, (12.4±2.2)mGy, (7.4±1.2)mGy, (14.2±2.5)mGy and( 10.4±1.9)mGy, respectively. The endovascular robotic system completed the cerebral angiography in Bama mini-pigs successfully. The average cannulation time for left innominate artery, right innominate artery, right subclavian artery, common internal carotid trunk, left internal carotid artery and right internal carotid artery was (41.5±6.8)s, (29.1±3.7)s, (40.7±5.5)s, (40.1±5.8)s, (59.6±9.0)s and( 60.3±10.1)s, respectively, while the average exposure dose was (40.6±6.5)mGy, (36.0±5.2)mGy, (39.8±6.1)mGy, (43.9±6.7)mGy, (51.0±7.4)mGy and( 50.1±7.8)mGy, respectively. There was no significant difference between robotic and conventional group in success rate, cannulation time and exposure dose. Conclusion: The remote digital control endovascular robotic system could cannulate the target vessel in both vascular model and complete the cerebral angiography in Bama mini-pigs, which shows the feasibility of using this robotic system in endovascular intervention procedures under remote control.

Abstract
Kyoho grapes ( Vitis vinifera X V. labrusca) were stored under three different treatments at 0°C in 95% relative humidity for 60 days. Grapes in the first treatment were stored in to air (control), in the second treatment the grapes were stored in 80% O2 for 15 days and then transferred into air for 45 days, and in the third treatment the grapes were sprayed with 100ppm of gibberellic acid (GA)3 containing 100ppm of Tween 20 and then kept in air. Compared with the air control, high oxygen pretreatment (HOP) and GA3 maintained higher fruit detachment force and membrane integrity, markedly reduced berry drop, rachis browning and decay and delayed the decrease of soluble solids content (SSC) and vitamin C. In addition, HOP and GA3 retarded the conversion of protopectin to water-soluble pectin and improved berry firmness. HOP resulted in a significantly firmer berry, less berry drop, and more soluble solids content, total acidity and protopectin than those treated with GA3, but did not markedly reduce rachis browning and membrane integrity loss. There were no significant differences in fruit detachment force and water-soluble pectin levels between HOP and GA3. In conclusion, high O2 pretreatment and GA3application retained effectively the quality of harvested grapes.

Abstract
This meta‐analysis was conducted to estimate the association between matrix metalloproteinase‐1 (MMP‐1) expression and pelvic organ prolapse (POP) in women. Relevant studies published before 6 December 2015 were identified by searching PubMed, Ovid, EBSCO, and EMBASE. A total number of five case–control studies, including 182 POP cases and 192 controls, were identified. The results indicated that women without POP had a lower MMP‐1 level of expression compared with women with POP (odds ratio = 0.54, 95% confidence interval: 0.43–0.67, P = 0.000). After stratification by biopsy site, ethnicity, or menopausal status, this finding was also confirmed in the subgroup analysis with no significant changes. Egger's linear regression test revealed a potential publication bias (P = 0.028). The findings of our study indicate that women who suffer from POP have a higher expression level of MMP‐1 than women without POP.

Epicardial adipose tissue volume a diagnostic study for independent predicting disorder of circadian rhythm of blood pressure in patients with essential hypertension. Cell Mol Biol (Noisy-le-grand) 2016; 62:1-7.

Abstract
The aim of the study was to determine whether epicardial adipose tissue volume (EATV), a new cardiometabolic risk factor, is associated with circadian changes of blood pressure (BP) in patients with newly diagnosed essential hypertension. Ninety patients with newly diagnosed essential hypertension underwent ambulatory blood pressure monitoring for 24 h. EATV was measured using cardiac computed tomography. These patients were categorized into three groups according to their BP patterns (group 1, n=46, dipper hypertension, also called normal pattern; group 2, n=24, non-dipper hypertension; group 3, n=20, anti-dipper hypertension; group 2 and 3 are also called abnormal pattern). Data were collected retrospectively and compared between hypertensive patients with normal pattern and abnormal pattern. The normal pattern hypertensive patient had significant lower mean EATV and BP ((EATV, 91.3±29.4 cm3) than those of abnormal pattern patients including group 2 (EATV, 116.2±31.06cm3, <0.01) and group 3 (EATV, 124.8±28.5cm3, P<0.01). Mean systolic BP over 24 h (BPs24) and mean diastolic BP over 24 h (BPd24) of group 1 (BPs24, 135.7 ± 12.6 mmHg; BPd24, 83.6 ± 10.6 mmHg) were significantly lower than those of group 2 (BPs24, 150.1± 17.6 mmHg, P<0.01; BPd24, 93.2 ± 16.5 mmHg, P<0.01) and group 3 (BPs24, 154.1 ± 16.6mmHg, P<0.01; BPd24, 93.8 ± 17.5 mmHg; P<0.01). Bivariate correlation analysis showed that correlation coefficient of EATV with abnormal blood pressure mode was 0.500 (p<0.001), partial correlation coefficient after adjustment for waist circumference and body mass index was 0.469 (p<0.001). When multivariate backward logistic regression analysis was performed to assess the correlation of BP pattern with EAT volume, it showed that the prevalence of abnormal BP pattern (non-dipper and anti-dipper BP pattern) increased by 1.54 times after adjusting for age and gender per additional 10 cm3 of EAT volume. Receiver operating characteristic curve for EAT alone indicated that the cutoff value of 95.17cm3 had the best performance in predicting abnormal BP pattern with a sensitivity of 75.0% and a specificity of 72.7%. EATV was elevated in newly diagnosed and untreated patients with non-dipper hypertension and anti-dipper hypertension. EATV measured by cardiac computed tomography can be used to indicate the increased risk of circadian rhythm of blood pressure.

Cardiac Specific Overexpression of hHole Attenuates Isoproterenol-Induced Hypertrophic Remodeling through Inhibition of Extracellular Signal-Regulated Kinases (ERKs) Signalling. Curr Mol Med 2016; 16:515-23.

Abstract
The human Hole gene (hHole) encodes a six-transmembrane protein with 319- amino acids. Our previous study showed that hHole was strongly expressed in adult heart and may act as a suppressor of extracellular signal-regulated kinases (ERKs), overactivation of which contributed to pathological cardiac hypertrophy. In this study, it was observed that Hole expression was up-regulated in murine hypertrophic hearts. In a cardiac specific transgenic mouse model, it was observed that overexpression of hHole specifically in heart attenuated cardiac hypertrophy and fibrosis induced by isoproterenol (ISO), with blunted transcriptions of ERK1/2, total ERK1/2 proteins and phosphorylated ERK1/2 (p-ERK1/2) levels. Furthermore, overexpression of hHole in mice by hydrodynamic tail-vein injection with hHole plamids also inhibited cardiac hypertrophy induced by ISO. Our work identified hHole as a novel repressor of cardiac hypertrophy, and provided new insights into the possible target for the prevention or treatment of cardiac diseases.
