Abstract
The vertex potential is the largest response that can be recorded in the electroencephalogram of an awake, healthy human. It is elicited by sudden and intense stimuli, and is composed by a negative–positive deflection. The stimulus properties that determine the vertex potential amplitude have been well characterized. Nonetheless, its functional significance remains elusive. The dominant interpretation is that it reflects neural activities related to the detection of salient stimuli. However, given that threatening stimuli elicit both vertex potentials and defensive movements, we hypothesized that the vertex potential is related to the execution of defensive actions. Here, we directly compared the salience and motoric interpretations by investigating the relationship between the amplitude of laser-evoked potentials (LEPs) and the response time of movements with different defensive values. First, we show that a larger LEP negative wave (N2 wave) predicts faster motor response times. Second, this prediction is significantly stronger when the motor response is defensive in nature. Third, the relation between the N2 wave and motor response time depends not only on the kinematic form of the movement, but also on whether that kinematic form serves as a functional defense of the body. Therefore, the N2 wave of the LEP encodes key defensive reactions to threats.

Abstract
OBJECTIVE To evaluate the efficacy of aspiration in an opposite position to deal with pneumothorax after CT-guided lung biopsy. METHODS A retrospective study was developed involving 210 patients with pneumothorax who had undergone CT-guided percutaneous core biopsies from January 2012 to March 2014 for various pulmonary lesions. Asymptomatic patients with minimal pneumothorax were treated conservatively. Simple manual aspiration was performed for symptomatic patients with minimal pneumothorax and for all patients with moderate to large pneumothorax. An opposite position aspiration was performed when simple manual aspiration failed. The efficacy of simple manual aspiration and the opposite position aspiration was observed. RESULTS Among 210 patients with pneumothorax, 128 (61.0%) asymptomatic patients with minimal pneumothorax were treated conservatively. The remaining 82 were treated with attempted simple manual aspiration. Out of these 82 patients, simple manual aspiration was successful in 58 (70.7%, 58/82) cases. The complete and partial regression rates were 17.2% (10/58) and 82.8% (48/58), respectively. In the other 24 patients (29.3%, 24/82), simple aspiration technique was ineffective. An opposite position (from prone to supine or vice versa) was applied, and a new biopsy puncture site was chosen for reaspiration. This procedure was successful in 22 patients but not in 2 patients who had to have a chest tube insertion. The complete and partial regression rates were 25.0% (6/24) and 66.7% (16/24), respectively. Applying the new method, the total effective rate of aspiration improved significantly from 70.7% (58/82) to 97.6% (80/82). CONCLUSION The opposite position aspiration can be safe, effective and minimally invasive treatment for CT-guided lung biopsy-induced pneumothorax thus reducing the use of chest tube significantly. ADVANCES IN KNOWLEDGE (1) Opposite position aspiration can elevate the success rate of aspiration significantly (from 70.7% to 97.6% in our study); (2) this procedure is a safe, effective and minimally invasive treatment for pneumothorax caused by biopsy; and (3) opposite position aspiration is a useful technique to reduce the use of chest tube, which has clinical significance.

Abstract
Insulin-like growth factor binding protein 2 (IGFBP2) is a pleiotropic oncogenic protein that has both extracellular and intracellular functions. Despite a clear causal role in cancer development, the tumor-promoting mechanisms of IGFBP2 are poorly understood. The contributions of intracellular IGFBP2 to tumor development and progression are also unclear. Here we present evidence that both exogenous IGFBP2 treatment and cellular IGFBP2 overexpression lead to aberrant activation of EGFR, which subsequently activates STAT3 signaling. Furthermore, we demonstrate that IGFBP2 augments the nuclear accumulation of EGFR to potentiate STAT3 transactivation activities, via activation of the nuclear EGFR signaling pathway. Nuclear IGFBP2 directly influences the invasive and migratory capacities of human glioblastoma cells, providing a direct link between intracellular (and particularly nuclear) IGFBP2 and cancer hallmarks. These activities are also consistent with the strong association between IGFBP2 and STAT3-activated genes derived from the TCGA database for human glioma. A high level of all 3 proteins (IGFBP2, EGFR and STAT3) was strongly correlated with poorer survival in an independent patient dataset. These results identify a novel tumor-promoting function for IGFBP2 of activating EGFR/STAT3 signaling and facilitating EGFR accumulation in the nucleus, thereby deregulating EGFR signaling by 2 distinct mechanisms. As targeting EGFR in glioma has been relatively unsuccessful, this study suggests that IGFBP2 may be a novel therapeutic target.

Abstract
Pez functions as an upstream negative regulator of Yorkie (Yki) to regulate intestinal stem cell (ISC) proliferation and is essential for the activity of the Hippo pathway specifically in the Drosophila midgut epithelium. Here we report that Suppressor of Deltex (Su(dx)) acts as a negative regulator of Pez. We show that Su(dx) targets Pez for degradation both in vitro and in vivo. Overexpression of Su(dx) induces proliferation in the fly midgut epithelium, which can be rescued by overexpressed Pez. We also demonstrate that the interaction between Su(dx) and Pez, bridged by WW domains and PY/PPxY motifs, is required for Su(dx)-mediated Pez degradation. Furthermore, we find that Kibra, a binding partner of Pez, stabilizes Pez via WW-PY/PPxY interaction. Moreover, PTPN14, a Pez mammalian homolog, is degraded by overexpressed Su(dx) or Su(dx) homologue WWP1 in mammalian cells. These results reveal a previously unrecognized mechanism of Pez degradation in maintaining the homeostasis of Drosophila midgut.

Abstract
OBJECTIVE To analyze the trends of multiple births rates and their perinatal outcomes in Zhejiang province from 2008 to 2013. METHODS Data were obtained from hospital-based perinatal mortality surveillance system in Zhejiang, including all the hospitals in 30 monitoring counties (districts). All births (28 or more weeks of gestation) born in the monitoring hospitals were included in our study within 7 days after delivery from 2008 to 2013. Chi-square test was performed for statistical analyses for comparisons between regions. Trends in the incidence of multiple births and causes of perinatal death were analyzed using chi-square test for trend. RESULTS From 2008 to 2013, the multiple births rate in Zhejiang province was increased and the rates were 2.32% (5 551/239 636), 2.49% (6 053/243 452), 2.61% (6 549/250 594), 2.82% (7 758/275 105), 2.91% (8 803/302 447) and 3.06% (9 051/295 709), respectively. And the perinatal mortality rates for multiple births were 4.32% (240/5 551), 3.45% (209/6 053), 3.76% (246/6 549), 2.86% (222/7 758), 2.77% (244/8 803) and 2.11% (191/9 051), respectively. A significant drop in the perinatal mortality rates for multiple births was observed between 2008 and 2013 (χ(2) trend = 66.52, P < 0.001). There was a significantly greater risk for perinatal death to multiple births when compared with single birth (OR = 3.62, 95% CI: 3.42-3.83). The three leading causes of perinatal death for multiple births were birth defect, premature and/or low birth weight, and twin-twin transfusion syndrome. CONCLUSION The multiple births rates in Zhejiang province showed an increasing trend. The perinatal mortality rates for multiple births were decreased annually, however, it was still higher than those in developed countries.

Abstract
Transient sensory, motor or cognitive event elicit not only phase-locked event-related potentials (ERPs) in the ongoing electroencephalogram (EEG), but also induce non-phase-locked modulations of ongoing EEG oscillations. These modulations can be detected when single-trial waveforms are analysed in the time-frequency domain, and consist in stimulus-induced decreases (event-related desynchronization, ERD) or increases (event-related synchronization, ERS) of synchrony in the activity of the underlying neuronal populations. ERD and ERS reflect changes in the parameters that control oscillations in neuronal networks and, depending on the frequency at which they occur, represent neuronal mechanisms involved in cortical activation, inhibition and binding. ERD and ERS are commonly estimated by averaging the time-frequency decomposition of single trials. However, their trial-to-trial variability that can reflect physiologically-important information is lost by across-trial averaging. Here, we aim to (1) develop novel approaches to explore single-trial parameters (including latency, frequency and magnitude) of ERP/ERD/ERS; (2) disclose the relationship between estimated single-trial parameters and other experimental factors (e.g., perceived intensity). We found that (1) stimulus-elicited ERP/ERD/ERS can be correctly separated using principal component analysis (PCA) decomposition with Varimax rotation on the single-trial time-frequency distributions; (2) time-frequency multiple linear regression with dispersion term (TF-MLRd) enhances the signal-to-noise ratio of ERP/ERD/ERS in single trials, and provides an unbiased estimation of their latency, frequency, and magnitude at single-trial level; (3) these estimates can be meaningfully correlated with each other and with other experimental factors at single-trial level (e.g., perceived stimulus intensity and ERP magnitude). The methods described in this article allow exploring fully non-phase-locked stimulus-induced cortical oscillations, obtaining single-trial estimate of response latency, frequency, and magnitude. This permits within-subject statistical comparisons, correlation with pre-stimulus features, and integration of simultaneously-recorded EEG and fMRI. ERP/ERD/ERS are reliably isolated using PCA + Varimax rotation on single-trial TFDs. TF-MLRd enhances the SNR of ERP/ERD/ERS in single trials. TF-MLRd provides an unbiased estimation of single-trial parameters of ERP/ERD/ERS. Availability of single-trial estimates permits within-subject statistical comparison.

Abstract
OBJECTIVE To investigate the effects of a hormone replacement preparation containing 1 mg estradiol plus 2 mg drospirenone on menopausal symptoms, blood lipids, and bone turnover markers in postmenopausal women. METHODS A prospective, self-controlled trial was conducted in 64 Chinese postmenopausal women aged 45-60 (mean 52.5 ± 3.37) years who were treated with estradiol-drospirenone for at least 6 months. The Kupperman index, blood lipid concentrations, bone mineral density, and bone turnover markers were measured before (baseline) and at 1, 3, and 6 months after treatment. RESULTS In comparison with baseline, the Kupperman index score was significantly improved at 1, 3, and 6 months after estradiol-drospirenone treatment (20.57 ± 6.52 vs. 16.37 ± 5.19, 13.34 ± 4.52, and 12.70 ± 4.42, respectively; all p < 0.01). After 6 months of treatment, concentrations of low density lipoprotein cholesterol, triglycerides, and total cholesterol were significantly decreased, high density lipoprotein cholesterol concentrations were significantly increased (all p < 0.05), and bone mineral densities of the lumbar spine and hip were significantly improved (both p < 0.001 compared with baseline). At both 3 and 6 months after treatment, bone alkaline phosphatase concentrations were significantly decreased compared with baseline (61.14 ± 12.38 IU/l and 58.77 ± 11.35 IU/l, respectively, vs. 65.81 ± 14.75 IU/l; p < 0.05), as were tartrate-resistant acid phosphatase concentrations (5.99 ± 2.98 IU/l and 4.90 ± 2.90 IU/l, respectively, vs. 6.15 ± 3.02 IU/l; p < 0.05). CONCLUSION Estradiol-drospirenone effectively alleviates menopausal symptoms and also has beneficial effects on blood lipids and bone metabolism.

Abstract
To investigate the fast ion behavior, a fast ion D-alpha (FIDA) diagnostic system has been planned and is presently under development on Experimental Advanced Superconducting Tokamak. The greatest challenges for the design of a FIDA diagnostic are its extremely low intensity levels, which are usually significantly below the continuum radiation level and several orders of magnitude below the bulk-ion thermal charge-exchange feature. Moreover, an overlaying Motional Stark Effect (MSE) feature in exactly the same wavelength range can interfere. The simulation of spectra code is used here to guide the design and evaluate the diagnostic performance. The details for the parameters of design and hardware are presented.

Abstract
Drosophila Hippo signaling regulates Wts activity to phosphorylate and inhibit Yki in order to control tissue growth. CK2 is widely expressed and involved in a variety of signaling pathways. In this study we report that Drosophila CK2 promotes Wts activity to phosphorylate and inhibit Yki activity, which is independent of Hpo-induced Wts promotion. In vivo, CK2 overexpression suppresses hpo mutant-induced expanded (Ex) up-regulation and overgrowth phenotype, whereas it cannot affect wts mutant. Consistent with this, knockdown of CK2 up-regulates Hpo pathway target expression. We also found that Drosophila CK2 is essential for tissue growth as a cell death inhibitor as knockdown of CK2 in the developing disc induces severe growth defects as well as caspase3 signals. Taken together, our results uncover a dual role of CK2; although its major role is promoting cell survive, it may potentially be a growth inhibitor as well.

Abstract
OBJECTIVE The aim of this study was to evaluate the postoperative changes in hemodynamics and biochemical indices in pediatric recipients of live-donor liver transplants (LDLT). METHODS Hemodynamics and biochemical indices (coagulation function, electrolytes, kidney function, liver function, and blood analysis) were monitored on the day before and the 1st, 3rd, 5th, and 7th days after the procedure in 20 children who underwent LDLT from June 2006 to January 2009. RESULTS Compared with preoperative measurements, systolic and diastolic blood pressure and mean arterial pressure increased and prothrombin time was prolonged significantly during the first 7 days after LDLT (P < .05). Fibrinogen, platelet count, total protein, globulin, and blood magnesium decreased significantly (P < .05). Liver enzymes (aspartate transaminase [AST], alanine transaminase [ALT]) and blood sodium increased significantly; serum potassium and calcium declined on the first postoperative day (P < .05). On the 7th day, AST returned to nearly normal (P < .05) and ALT returned to the preoperative levels. Blood urea nitrogen fluctuated within the normal range (P < .05). Total and direct bilirubin decreased on the 1st day but returned to near normal levels on the 7th day (P <.001). CONCLUSIONS Our data demonstrated postoperative changes in hemodynamics, electrolytes, and biochemical indices in pediatric LDLT recipients. The changes in clotting factors and platelet count did not result in severe coagulation function disorder; kidney function was normal. Changes in liver enzymes and bilirubin compared with the preoperation indices were within the regulatory scope of liver and did not result in severe complications. These preliminary postoperative trends suggest that further prospective evaluation is needed.

The nested polymerase chain reaction (PCR) method was used for the amplification of the influenza A H1N1 virus hemagglutinin monoclonal antibody light-chain and heavy-chain genes. Sequence analysis of the obtained genes was then used to identify common cloning methods of the mouse immunoglobulin-kappa (Igκ) light-chain and heavy-chain variable gene regions. Twenty-two pairs of amplification primers for the mouse Igκ light-chain and heavy-chain variable gene regions were designed, and 6 mouse anti-human H1N1 influenza virus hemagglutinin monoclonal antibody light-chain and heavy-chain variable gene regions were cloned and sequenced. Comparative analysis was conducted between our results and the mouse Ig sequences published in the National Center of Biotechnology Information (NCBI). The nested PCR method effectively avoided cloning the pseudogenes of the monoclonal antibody, and the amino acid sequence obtained was consistent with the characteristics of the mouse Ig variable region. A general method of cloning the mouse Ig light-chain and heavy-chain variable gene regions was established, which provides a basis for further cloning of mouse monoclonal antibody variable gene regions. This study also provides data for further studies of H1N1 influenza virus hemagglutinin antibody binding sites.

Abstract
OBJECTIVE The aim of this study was to observe clinical curative effects of combination application of dimethylbiguanide and pioglitazone and single application of pioglitazone in patients with polycystic ovarian syndrome (PCOS) complicated with insulin resistance (IR). MATERIALS AND METHODS Forty cases of patients with PCOS complicated with IR were investigated, and 20 cases of infertile women without PCOS were taken as the control group. PCOS group was divided into group A and group B according to body mass index (BMI) to detect glucose and lipids metabolism indicators, C reactive protein (CRP), etc. There were 20 cases in group A (Pioglitazone) and 20 cases in group B (dimethylbiguanide and pioglitazone). After treatment for 12 weeks, changes of the above various indicators were compared. RESULTS After treatment, insulin resistance index and serum testosterone (T) of two groups patients with PCOS significantly reduced (p < 0.05). Compared to before treatment, BMI of group B significantly reduced (p < 0.05). For INS at two hours after treatment, group B reduced more significantly (p < 0.05). CONCLUSION The combination of dimethylbiguanide and pioglitazone was more effective for the treatment of PCOS complicated with IR than simple pioglitazone; chronic inflammation occurrence was possibly one of reasons for insulin sensitivity reduction of patients with PCOS.

Abstract
Short-term risk assessment instrument owns great importance for psychiatric nurses in China; however, the lack of a standardized violence risk assessment instrument has disadvantaged them in clinical practice. The Brøset Violence Checklist (BVC), a behavioural observation tool, is the most frequently cited instrument available for evaluating violence risk in psychiatric inpatients, then worth to be tested in Chinese culture. This study, conducted in two closed wards in a psychiatric hospital in Beijing, revealed that the instrument has favourable reliability, validity and predictive accuracy in Chinese population. BVC provides nurses with a quick and easily administered method to screening out patients with violence potential, thus allowing for early intervention. Feedback from the nurses was quite encouraging and the further use of BVC seems promising. The lack of standardized violence risk assessment instrument has disadvantaged nurses in clinical practice in China, where violent behaviour is an increasing problem. This study conducted a validation of the Brøset Violence Checklist that has proven effective in violence risk prediction in other countries. A sample of 296 patients consecutively admitted to two wards of a psychiatric hospital in Beijing was recruited. These patients were assessed on day shift and evening shift for the first seven days of hospitalization. Violence data and preventive measures were concurrently collected from nursing records and case reports. A total of 3707 assessments for 281 patients were collected revealing 93 episodes of violence among 55 patients. Receiver operating characteristics yielded an area under the curve of 0.85. At the cut-off point of one, its sensitivity/specificity was 78.5%/88.2% and the corresponding positive/negative predictive value was 14.6%/99.4%. In some false positive cases, intense preventive measures had been implemented. Positive feedback from the nurses was gained. The Brøset Violence Checklist was proved as an easy-to-use and time-saving instrument, therefore, regarded as a promising tool to determine if the psychiatric users are potentially violent in the short term.

Abstract
We present the case of a term neonate who underwent a diagnostic eye examination on day one for possible genetic disorders. Five minutes after Cyclomydril (0.2% clyclopentolate and 1% phenylephrine) eye drops were instilled, a focal seizure lasting for approximately one hour occurred. The electroencephalograph (EEG) was normal but the magnetic resonance imaging (MRI) revealed calcifications in the bilateral periventricular regions. Urine CMV-DNA and maternal serum CMV-IgM were both positive. Auditory brainstem testing suggested severe sensoneural hearing loss. The baby was treated for congenital CMV infection and did not have further seizures. In this case the congenital CMV infection may have been the predisposing factor to central nervous system (CNS) toxicity induced by cyclopentolate. The exact mechanism is unknown but severe neurological impairment may be considered a contraindication for cyclopentolate eye drops in the neonate. To our knowledge, this is the first report of seizures occurring within the first week of life secondary to cyclomydril eye drops in a term neonate.

Abstract
Whether primary sensory cortices are essentially multisensory or whether they respond to only one sense is an emerging debate in neuroscience. Here we use a multivariate pattern analysis of functional magnetic resonance imaging data in humans to demonstrate that simple and isolated stimuli of one sense elicit distinguishable spatial patterns of neuronal responses, not only in their corresponding primary sensory cortex, but in other primary sensory cortices. These results indicate that primary sensory cortices, traditionally regarded as unisensory, contain unique signatures of other senses and, thereby, prompt a reconsideration of how sensory information is coded in the human brain. Human primary sensory cortices are traditionally regarded as being able to process only one sensory modality. Liang and colleagues use brain imaging to show that, as well as being processed in typically corresponding cortical areas, different sensory modalities are also processed in atypical cortical areas.
