Abstract
UNLABELLED This study was designed to investigate the association of circadian gene single nucleotide polymorphisms (SNPs) with the risk of osteoporosis. We found that the rs3781638 GG genotype was positively associated with osteoporosis prevalence in females, whereas the rs2292910 AC genotype was negatively associated with osteoporosis prevalence in a geriatric cohort. INTRODUCTION Studies have shown that disruption of endogenous circadian rhythms may increase the risk of developing type II diabetes and obesity, which are reportedly associated with osteoporosis (OP). Thus, abnormalities of circadian genes may indirectly induce OP. Here, we investigated the association of OP with 14 SNPs located in seven circadian genes. METHODS The research subjects, geriatric residents of Shanghai Minhang, China, diagnosed with OP (N = 171) or osteopenia (N = 226) or without specific diseases (N = 200), were genotyped for 14 genetic variants of circadian genes by competitive allele-specific polymerase chain reaction. The prevalence of polymorphisms among the subject groups and the association between the SNPs and osteoporosis were investigated. RESULTS Among the 14 genotyped SNPs, we found an association between the CRY2 gene rs2292910 SNP and osteoporosis (r = -0.082, p = 0.045) in the geriatric cohort. We found a decreased risk between cryptochrome 2 rs2292910 and OP (A/C odds ratio = 0.647, p = 0.044) but an increased risk between MTNR1B rs3781638 and OP (G/G odds ratio = 2.058, p = 0.044). CONCLUSION For the first time, we show that Cry 2 rs2292910 and MTNR1B rs3781638 are associated with osteoporosis in a Chinese geriatric cohort. Therefore, targeting the abnormalities of the CRY2 and MTNR1B genes may be a potential strategy to treat and/or to prevent osteoporosis.

Abstract
Activin A (Act A), a member of transforming growth factor-β (TGF-β) superfamily, is an early gene in response to cerebral ischemia. Growing evidences confirm the neuroprotective effect of Act A in ischemic injury through Act A/Smads signal activation. In this process, regulation networks are involved in modulating the outcomes of Smads signaling. Among these regulators, crosstalk between c-Jun N-terminal kinase (JNK) and Smads signaling has been found in the TGF-β induced epithelial-mesenchymal transition. However, in neural ischemia, the speculative regulation between JNK and Act A/Smads signaling pathways has not been clarified. To explore this issue, an Oxygen Glucose Deprivation (OGD) model was introduced to nerve-like PC12 cells. We found that JNK signal activation occurred at the early time of OGD injury (1 h). Act A administration suppressed JNK phosphorylation. In addition, JNK inhibition could elevate the strength of Smads signaling and attenuate neural apoptosis after OGD injury. Our results indicated a negative regulation effect of JNK on Smads signaling in ischemic injury. Taken together, JNK, as a critical site for neural apoptosis and negative regulator for Act A/Smads signaling, was presumed to be a molecular therapeutic target for ischemia.

Abstract
OBJECTIVE To analyze the characteristics and factors affecting the recurrence in esophageal cancer within the first year after esophagectomy. METHODS We reviewed retrospectively the clinical and follow-up data of 320 patients who underwent surgical treatment from April 2009 to April 2013 in Sichuan Provincial Cancer Hospital. RESULTS 72 cases (72/320, 22.5%) had tumor recurrence within the first year after surgery. The average recurrence time was 6.89±3.53 months and the median recurrence time was 6.02 months. Univariate analysis showed that T stage, N stage, G grade, and pathological stage are related to the recurrence (P<0.05 for all). Logistic regression analysis showed that pathological stage is an independent risk factor for recurrence (P=0.002). There were 46 cases (46/72, 63.9%) of local recurrence and 26 cases (26/72, 36.1%) of distant metastasis. Among the 46 cases of local recurrence, 27 cases (27/46, 58.7%) had upper mediastinal lymph node metastasis. Among the 26 cases of distant metastasis, there were 11 cases (11/26, 42.3%) of pulmonary metastasis. Among the 72 cases of recurrence, the average number of dissected lymph nodes and involved nodes were 29.40±11.41 and 4.37±5.65, respectively, in patients with distant metastasis, and 21.18±10.37 and 1.91±2.14, respectively, in patients with local recurrence. Both the number of dissected and involved lymph nodes were significantly higher in the patients with distant metastasis (P<0.05). CONCLUSIONS Lymph node metastasis is the most common pattern of recent relapse after esophagectomy, and pathological stage is an independent risk factor for recurrence within the first year after surgery. Standardized lymph node dissection and rational treatment strategy is the key measures to reduce early recurrence of esophageal cancer.

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

Abstract
Baseline holder (BLH) circuits are used widely to stabilize the analog output of application-specific integrated circuits (ASICs) for high-count-rate applications. The careful design of BLH circuits is vital to the overall stability of the analog-signal-processing chain in ASICs. Recently, we observed self-triggered fluctuations in an ASIC in which the shaping circuits have a BLH circuit in the feedback loop. In fact, further investigations showed that methods of enhancing small-signal stabilities cause an even worse situation. To resolve this problem, we used large-signal analyses to study the circuit's stability. We found that a relatively small gain for the error amplifier and a small current in the non-linear stage of the BLH are required to enhance stability in large-signal analysis, which will compromise the properties of the BLH. These findings were verified by SPICE simulations. In this paper, we present our detailed analysis of the BLH circuits, and propose an improved version of them that have only minimal self-triggered fluctuations. We summarize the design considerations both for the stability and the properties of the BLH circuits.

Abstract
A 58-year-old male was scheduled to undergo radical gastrectomy for cancer under general anesthesia. The patient developed agitation and irregular breathing after receiving a single dose of atropine (0.5 mg) to treat bradycardia immediately prior to induction of anesthesia. Within 5 min after the atropine injection, the patient became unresponsive with facial flushing and diaphoresis. When a drop in oxygen saturation was observed, a laryngeal mask airway was inserted after administering a small bolus dose of propofol (80 mg) and the patient was ventilated with 100% oxygen. Physostigmine was not administered because of the relatively low dose of atropine and the fact that his symptoms were not totally consistent with central anticholinergic syndrome (CAS). The differential diagnosis at the time also included an acute cardiovascular event and an idiosyncratic reaction to atropine. The patient fully recovered within 80 min from this highly unusual reaction to a single 0.5 mg IV dose of atropine.

Abstract
OBJECTIVES To evaluate the clinical efficacy of systemic chemotherapy combined with intraperitoneal hyperthermic perfusion in advanced gastric cancer patients with malignant ascites. PATIENTS AND METHODS Forty-eight gastric cancer patients with malignant ascites who were admitted to our hospital were selected and randomly divided into the hyperthermic perfusion and control groups. The control group only received systemic chemotherapy, and the hyperthermic perfusion group received systemic chemotherapy combined with intraperitoneal hyperthermic chemoperfusion. The therapeutic efficacy, the survival time and the associated toxicity were determined for the two groups. RESULTS The efficacy was significantly higher in the hyperthermic perfusion group (85.7%) than in the control group (30.0%) (P 0.05). The median progression-free survival (PFS) was significantly longer in the hyperthermic perfusion group (12 months) compared with the control group (6 months) (P < 0.05). The median overall survival (OS) was significantly longer in the hyperthermic perfusion group (21 months) compared with the control group (9 months) (P < 0.05). There was a significantly higher 1-year survival rate in the hyperthermic perfusion group (89.3%) than in the control group (36.4%) (P < 0.05); however, there was no significant difference in the 3-year survival rate (10.7% vs. 10.0%). The Karnofsky Performance Status (KPS) score in the hyperthermic perfusion group increased significantly from 62.8 ± 1.84 to 74.3 ± 5.0 after hyperthermic chemoperfusion (P < 0.05). CONCLUSION Systemic chemotherapy combined with intraperitoneal hyperthermic perfusion exhibited significant clinical efficacy in advanced gastric cancer patients with malignant ascites, helped control ascites, improved the quality of life and extended PFS and OS. This treatment regimen is worth promoting.

Abstract
The defect of esophagus after surgical excision in patients is usually replaced by autologous stomach, jejunum, or colon. The operation brings severe trauma and complications. Using artificial esophagus to replace the defect in situ can reduce the operative trauma, simplify the operative procedures, and decrease the influence to digestive function. A variety of experiments have been designed for developing a practical artificial esophagus. Nevertheless, a safe and reliable artificial esophagus is not yet available. The objective is to evaluate the possibility of the artificial esophagus made of non-degradable polyurethane materials being used in reconstruction of the segmental defect of cervical esophagus in beagles, observe the regeneration of esophageal tissue, and gather experience for future study. The cervical esophageal defects in 13 beagles were designed to 2-cm long and were constructed by the artificial esophagus made of non-degradable polyurethane materials. Nutrition supports were given after the operation. The operative mortality, anastomotic leakage, migration of artificial esophagus, and dysphagia were followed up. The regeneration of the esophageal tissues was evaluated by histopathology and immunohistochemical labeled streptavidin-biotin method. The surgical procedures were successfully completed in all beagles, and 12-month follow-ups were done. Only one beagle died of severe infection, and all others survived until being killed. The anastomotic leakage occurred in nine beagles, most of them (8/9) were cured after supportive therapy. The migration of artificial esophagus occurred in all 12 surviving beagles, and one artificial esophagus stayed in situ after migration. All 12 surviving beagles showed dysphagia with taking only fluid or soft food. No beagle died of malnutrition. The neo-esophagus was composed of granulation tissue, and the inner surface was covered by epithelium in 2-3 months completely. But the inner surface of neo-esophagus with artificial esophagus staying in situ after migration was not covered by epithelium, and the granulation tissue was infiltrated by a great deal of inflammatory cells. Antibodies against cytokeratin were positively expressed in epithelium of neo-esophagus. Up to 12 months after operation, antibodies against smooth muscle actin and desmin were both negatively expressed in neo-esophagus. The artificial esophagus made of non-degradable polyurethane reconstructing cervical esophageal defect is practicable. Although there are some problems, including anastomotic leakage, migration, and dysphagia, they are not lethal following good supportive therapy. The esophageal epithelium can regenerate with the supporting role of artificial esophagus. In the future, deformable artificial esophagus should be improved, and a much longer follow-up will be performed to evaluate whether the esophageal gland and skeletal muscle can regenerate.

Abstract
The fore- and hindlimb of yak have been studied by the gross anatomical methods and standard histological techniques. The artery of ungula was also determined by X-ray and acrylonitrile-butadiene-styrene casting. Anatomical features of the forelimb of yak resemble those of hindlimb, including hoof periphery, hoof coronal, hoof wall, hoof sole, and hoof sphere. The forelimb and hindlimb are almost the same in histological structure. The epidermis comprised all 5 strata: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum and stratum basale. The papillary layers and dermal lamellae contained a variable amount of capillary as well as collagen and elastic fibres. Many venules and arteriovenous anastomosis were distributed among the reticular layer. Subcutaneous tissue was composed of rich adipose and connective tissue in hoof periphery, hoof coronal, and, especially, hoof sphere. Major arteria in forelimb of yak include arteria digitalis palmaris communis III and arteriae digitales palmares propriae III and IV axialis. Those in hindlimb include arteria digitalis plantaris communis III and arteria digitalis plantaris propria III and IV axialis. Our findings highlight the main morphological features of yak and provide a morphological basis useful to researchers using yak hoof.

Abstract
This study reports the cloning of a sucrose transporter gene, PsSUT1, from the leaf of tree peony (Paeonia suffruticosa Lind. cv 'Huhong'). Expression patterns were examined in different organs and at different developmental stages. The full-length cDNA of PsSUT1 consisted of a 2001-bp sequence containing a 1557-bp open reading frame, encoding 519 amino acids with a conserved domain typical of the glycoside-pentoside-hexuronide superfamily. The amino acid sequence of PsSUT1 in tree peony shared high homology with that of other plants. At different developmental stages, PsSUT1 was expressed in roots, stems, leaves, and petals. Its expression level in stems was 10.9-fold higher than in petals at the flowering stage. Expression of PsSUT1 at the flowering stage was highest during flower development. The significant differences in PsSUT1 expression observed among developmental stages and organs were closely related to changes in sucrose content during flower opening. These results form the basis for further research on the molecular mechanisms of carbohydrate metabolism and transport during flower development in tree peony.

Abstract
INTRODUCTION The esophageal squamous cell carcinoma (ESCC) is the predominant pathological type and accounts for more than 80 % of esophageal cancer in China. The successful use of anti-epidermal growth factor receptor (EGFR) treatment in head and neck squamous cell carcinoma provides the rationale for introducing anti-EGFR targeting treatment in ESCC. One of our prospective phase II clinical trials analyzed the efficacy of nimotuzumab, an anti-EGFR agent, combined with chemotherapy (paclitaxel and cisplatin) to treat unresectable ESCC. MATERIALS AND METHODS We analyzed the correlation of the clinical response with EGFR expression by immunohistochemical staining (IHC). RESULTS Totally 55 tumor samples were analyzed. 18/55 (32.7 %) cases were with high EGFR expression while the other 37/55 (67.3 %) cases were with low to moderate EGFR expression. The expression of EGFR was not related to gender, age, tumor location, tumor differentiation and clinical stage of disease. The objective response rate (ORR) in high EGFR expression group was 55.6 % (10/18) while that in low to moderate EGFR expression group was 54.1 % (20/37) (P = 0.57). Both the progression-free survival (PFS) and overall survival (OS) in high EGFR expression group were much shorter than those in low to moderate EGFR expression group (PFS: 5.8 ± 0.5 vs. 11.0 ± 2.8 months, P = 0.007; OS: 9.7 ± 0.5 vs. 21.5 ± 1.5 months, P = 0.03). CONCLUSIONS The results showed that over-expression of EGFR was related to poor survival of ESCC. The over-expression of EGFR by IHC might not be an ideal predictive biomarker of nimotuzumab treatment. Other EGFR pathway-associated molecules should be analyzed in further studies.

Abstract
Purpose: To prepare and evaluate colon specific drug delivery system of diclofenac sodium for highly localized delivery to the colon.Methods: The colon specific drug delivery system was prepared as matrix-type microspheres using Ethyl Cellulose (EC), Cellulose Acetate Phthalate (CAP), and Eudragit L 100-55 by the Solvent Evaporation Method. Microspheres were evaluated for physical properties like drug content, particle size, bulk density and angle of repose.Results: The size range of the microcapsules was 228 to 608 μm while drug content was between 74.49 and 91.50 % depending on the polymer used and the polymer ratio. Mean bulk density was < 1.2 g/ml which indicates the good flow properties, while angle of repose was < 40 o, indicating free-flowing properties. The microspheres were spherical in shape with smooth and nonporous surface, except that the microspheres containing EC and CAP exhibited a rough and porous surface. The microspheres containing Eudragit L 100-55 in combination with other polymers gave better sustained release (78.9 and 76.6 % at the end of 8 h for formulation F4 and F5, respectively) than the others.Conclusion: Microspheres prepared with drug: EC: CAP ratio of 1:2:1 show the highest drug content, possess good flow properties and surface morphology, as well as promising drug release for colon specific drug delivery of diclofenac sodium for possible treatment of colorectal cancer.Keywords: Diclofenac, Colorectal cancer, Microspheres, Ethyl cellulose, Cellulose acetate phthalate, Eudragit L 100-55

Abstract
The aim of this in vivo study was to determine the existence of muscle-derived stem cells (MDSCs) in rat corpus cavernosum. Immunohistochemical and RT-PCR analyses were performed to determine the expression of the stem cell markers (Sca-1, Oct4, and desmin) in Sprague-Dawley (SD) rats in different age groups (10 rats in each group). Sca-1 was mainly expressed in blood vessels and cavernous sinus and demonstrated primarily cytoplasmic staining. Desmin was expressed mainly in muscle tissues and staining occurred mainly in the cytoplasm but also partially in the nucleus. An extremely small amount of double-positive stained cells (Sca-1/desmin) were detected near the cavernous sinus. Expression of the markers was significantly and negatively correlated with the age of the rats (P < 0.05). The RT-PCR results showed that the expression levels of Sca-1 and desmin significantly decreased with age (P < 0.05). Correlation analysis indicated that the expression of Sca-1 and desmin were significantly and negatively correlated with the age of rats (r = -0.929, P < 0.05). The present study provides evidence for the existence of MDSCs in rat corpus cavernosum. MDSCs may have therapeutic potential in the treatment of organic erectile dysfunction.

Abstract
BACKGROUND This study introduces a novel self-report instrument to measure children's time-use in physical and sedentary activities and examines the relationships between children's time-use and physical fitness and risks of obesity and diabetes. METHODS The new instrument utilizes a series of timelines, each representing an activity type. 188 children (53% girls) aged 10 to 14 year-old participated in the study. Their time-use data for two weekdays and one weekend day were collected. Anthropometrics and cardiovascular fitness were measured and children's BMI z-score and PACER z-score were computed. One-time blood draw for fasting glucose and insulin were used to calculate insulin resistance using homeostasis model assessment for insulin resistance (HOMAIR). RESULTS The reliability assessment of this instrument indicated a moderately reproducible procedure (ICC > 0.6) for six activity types. The validity correlation for motorized travel time was high (r = 0.226, P < 0.05) between self-report instrument and GPS tracks. PACER z-score was positively correlated with time-uses of play (r = 0.159, P < 0.05), and organized sports (r = 0.198, P < 0.05); and was highly inversely correlated with BMI z-score (r = -0.441, P < 0.0001) and HOMAIR (r = -0.472, P < 0.0001). Overall, only 14% of the children had physical activity for more than 60 minutes daily over three observation days. CONCLUSIONS This instrument is particularly useful in assessing children's activity patterns, especially for specific physical activities. The new instrument provides a reproducible measure of children's perception of their activities. Our results emphasize the temporal context which is critical to formulating effective interventions targeting physical activity increase in children. Further efforts are needed to understand the differences between activity time obtained by the new self-report instrument and GPS tracks.

Abstract
Clinically useful predictors of weight gain could be used to reduce the epidemic of post-kidney transplant obesity and resulting co-morbidities. The purpose of this study was to identify predictors of weight gain at 12 months following kidney transplant in a cohort of 96 recipients. Demographic, clinical, and environmental data were obtained at transplant and 12 months. Descriptive, correlational, and Bayesian network analysis were used to identify predictors. For the 52 (55.9%) recipients who gained weight, the average amount gained was 9.18 ± 6.59 kg. From the 15 baseline factors that met inclusion criteria, Bayesian network modeling identified four baseline predictors for weight gain: younger age, higher carbohydrate consumption, higher trunk fat percentage, and higher perception of mental health quality of life. Three are modifiable through either pre- or immediate post-transplant clinical intervention programs.

Abstract
Hypertension is the most significant modifiable risk factor for vascular cognitive impairment. However, influence of hypertension on the development of ischemic white matter injury and cognitive dysfunction is not fully understood. We compared cognitive functions and neuropathological outcomes of chronic cerebral hypoperfusion induced by bilateral common carotid artery occlusion (BCCAO) between normotensive rats (NRs) and spontaneously hypertensive rats (SHRs). SHRs developed earlier and more severe deficits in spatial memory performance than NRs following BCCAO. Although no significant changes in the gross structure of myelinated white matter or oligodendrocyte number were noted, BCCAO resulted in subtle myelin degeneration and paranodal structural alterations at the nodes of Ranvier, regardless of hypertension. Disruption of the blood-brain barrier (BBB) was predominantly observed in the white matter of SHRs following BCCAO, implying a role of hypertension in BBB dysfunction in chronic cerebral hypoperfusion. In chronic cerebral ischemia, long-standing hypertension may aggravate impairment of BBB integrity, and the leaky BBB may in turn exacerbate dysfunction in the white matter leading to worsening of spatial cognitive performance.

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
Quantitative trait locus (QTL) mapping is often conducted in line-crossing experiments where a sample of individuals is randomly selected from a pool of all potential progeny. QTLs detected from such an experiment are important for us to understand the genetic mechanisms governing a complex trait, but may not be directly relevant to plant breeding if they are not detected from the breeding population where selection is targeting for. QTLs segregating in one population may not necessarily segregate in another population. To facilitate marker-assisted selection, QTLs must be detected from the very population which the selection is targeting. However, selected breeding populations often have depleted genetic variation with small population sizes, resulting in low power in detecting useful QTLs. On the other hand, if selection is effective, loci controlling the selected trait will deviate from the expected Mendelian segregation ratio. In this study, we proposed to detect QTLs in selected breeding populations via the detection of marker segregation distortion in either a single population or multiple populations using the same selection scheme. Simulation studies showed that QTL can be detected in strong selected populations with selected population sizes as small as 25 plants. We applied the new method to detect QTLs in two breeding populations of rice selected for high grain yield. Seven QTLs were identified, four of which have been validated in advanced generations in a follow-up study. Cloned genes in the vicinity of the four QTLs were also reported in the literatures. This mapping-by-selection approach provides a new avenue for breeders to improve breeding progress. The new method can be applied to breeding programs not only in rice but also in other agricultural species including crops, trees and animals.

Abstract
BACKGROUND Liver metastasis is associated with poor prognosis in gastric cancer. Surgical resection and systemic chemotherapy have been reported to be effective in gastric cancer with liver metastasis (GCLM). However, the best strategy for GCLM has not been established. METHODS From May 2009 to July 2014, a consecutive series of GCLM patients in Zhongshan Hospital of Fudan University were studied. Treatment strategies were evaluated with regard to different extents of metastases. RESULTS A total of 163 patients were included. The overall survival was 10.1 months. Active treatment significantly prolongs the survival of GCLM patients. The overall survival time for patients with liver-limited metastases and extra-hepatic liver metastases was 11.6 mo and 8.7 mo, respectively (P = 0.012). The median survival time for liver-limited disease of H1, H2 and H3 was 14.2, 15.8, and 8.5 months, respectively (H3 vs H2, P = 0.001; H3 vs H1, P = 0.000; H1 vs H2, P = 0.900). Systemic chemotherapy was chosen as the main strategy for the 'extensive' patients with extra-hepatic metastases and H3 type liver-limited metastases. Patients' survival was benefited by multi-line chemotherapy. No differences were shown between systemic chemotherapy and curative resection or palliative resection in H1 and H2 liver-limited metastases (16.0 mo vs 12.0 mo, P = 0.711; 16.0 vs 18.8 months, P = 0.654). CONCLUSION Systemic chemotherapy was the main treatment for gastric cancer patients with liver metastases. Curative resection could be considered for highly selected patients.

Abstract
Several intraoperative ventilation strategies are available for obese patients. However, the same ventilation interventions have exhibited different effects on PaO2 /FIO2 concerning obese patients in different trials, and the issue remains controversial. Therefore, we conducted a network meta-analysis to identify the optimal mechanical ventilation strategy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, Embase, MEDLINE, CINAHL and Web of Science for studies published up to June 2014, and the PaO2 /FIO2 in obese patients given different mechanical ventilation strategies was assessed. We assessed the studies for eligibility and extracted data and then pooled the data and used a Bayesian fixed-effect model to combine direct comparisons with indirect evidence. Eligible studies evaluated different ventilation strategies for obese patients and reported the intraoperative PaO2 /FIO2 ratio, atelectasis and pulmonary compliance. Thirteen randomized controlled trials were included for network meta-analysis, including 476 patients who received 1 of 12 ventilation strategies. Volume-controlled ventilation with higher PEEP plus single recruitment manoeuvres (VCV + higher PEEP + single RM) was associated with the highest PaO2 /FiO2 ratio, improving intraoperative pulmonary compliance and reducing the incidence of intraoperative atelectasis.

Abstract
BACKGROUND Interactions between the thalamus and the cortex play an important role in consciousness. The thalamus as a homogenous structure is less strongly connected with the default mode network (DMN) in patients with disorders of consciousness (DOC), but the roles of specific thalamic nuclei are not clear. The purpose of this study was to investigate the functional connectivity between individual thalamic nuclei and the DMN in DOC patients. METHODS Nine DOC patients and nine age-matched healthy controls were scanned with functional magnetic resonance imaging (fMRI) at resting state. Data-driven independent component analysis and hypothesis-driven region of interest-based correlation analysis were performed. RESULTS In comparison with healthy controls, DOC patients had significantly decreased functional connectivity between the mediodorsal thalamus and brain areas within the DMN, including the medial prefrontal cortex and posterior cingulate cortex/precuneus. Patients and controls did not show significant differences in functional connectivity in other thalamic nuclei. CONCLUSION Our results suggest that functional connections between the mediodorsal thalamus and the DMN may play important roles in the pathogenesis of DOC.

Abstract
An annihilation signal of dark matter is searched for from the central region of the Milky Way. Data acquired in dedicated on-off observations of the Galactic center region with H.E.S.S. are analyzed for this purpose. No significant signal is found in a total of ∼9 h of on-off observations. Upper limits on the velocity averaged cross section, ⟨σv⟩, for the annihilation of dark matter particles with masses in the range of ∼300 GeV to ∼10 TeV are derived. In contrast to previous constraints derived from observations of the Galactic center region, the constraints that are derived here apply also under the assumption of a central core of constant dark matter density around the center of the Galaxy. Values of ⟨σv⟩ that are larger than 3×10^{-24} cm^{3}/s are excluded for dark matter particles with masses between ∼1 and ∼4 TeV at 95% C.L. if the radius of the central dark matter density core does not exceed 500 pc. This is the strongest constraint that is derived on ⟨σv⟩ for annihilating TeV mass dark matter without the assumption of a centrally cusped dark matter density distribution in the search region.

Abstract
We carried out a systematic review and meta-analysis to assess the efficacy and safety of phosphodiesterase type 5 (PDE5) inhibitors for treating erectile dysfunction (ED) after bilateral nerve-sparing radical prostatectomy (BNSRP). A literature review was performed to identify all published randomised double-blind, placebo-controlled trials of PDE5 inhibitors for the treatment of ED after BNSRP. The search included the following databases: MEDLINE, EMBASE and the Cochrane Controlled Trials Register. The reference lists of the retrieved studies were also investigated. Six publications involving a total of 1678 patients were used in the analysis, including six RCTs that compared PDE5 inhibitors (tadalafil, sildenafil, avanafil and vardenafil) with placebo. Co-primary efficacy end points: International Index of Erectile Function-Erectile Function (IIEF-EF) domain score [the standardised mean difference (SMD) = 4.04, 95% confidence interval (CI) = 2.87-5.22, P < 0.00001]; successful vaginal penetration (SEP2) [the odds ratio (OR) = 14.87, 95%CI = 4.57-48.37, P < 0.00001]; and successful intercourse (SEP3) (OR = 47, 95%CI = 3-13.98, P < 0.00001) indicated that PDE5 inhibitors was more effective than the placebo. Specific adverse events with PDE5 inhibitors included headache (12.08%), dyspepsia (6.76%) and flushing (6.52%), which were significantly less likely to occur with placebo. This meta-analysis indicates that PDE5 inhibitors to be an effective and well-tolerated treatment for ED after BNSRP.

Abstract
Group B Streptococcus (GBS) is one of the major pathogens of severe newborn sepsis and meningitis. Understanding its regional molecular epidemiology is helpful for regulating efficient prevention practice. A total of 160 GBS strains were collected from colonized pregnant women in six hospital settings in Beijing, China. Polymerase chain reaction (PCR) assays were used to identify the pilus island (PI), alp genes profiling of the alpha-like protein family, and capsular polysaccharide (cps) serotyping. The clonal relationships between strains were investigated using multilocus sequence typing (MLST). All isolates carried at least one pilus island. The most frequently detected pilus island was PI-2a alone (70 isolates, 43.8 %). The most prevalent alp gene was rib (60 isolates, 37.5 %). Moreover, a strong association was noted between alp genes, serotyping, and pilus island profiles. The GBS isolates under study hinted similar molecular epidemical characteristics in Beijing to those reported worldwide, but having their regional distributional features.

Abstract
The present study investigated the effects of chronic social defeat stress on several behavioral parameters, and the expression of dopaminergic markers, i.e., dopamine D1 receptors (D1Rs), dopamine D2 receptors (D2Rs), and dopamine and cyclic adenosine 3',5'-monophosphate-regulated phosphoprotein-32 (DARPP-32), in the prefrontal cortex (PFC), amygdala (AMY), and hippocampus (HIP) of mouse brains. After 10days of social defeat stress, the defeated mice were divided into two groups: one group underwent a series of behavioral tests. The other group was sacrificed on the 11th day and tissue samples were collected for Western blotting. The behavioral tests comprised tests of locomotion, light/dark preference, social interaction, as well as the novel object recognition test (NORT), Morris water maze, and forced swimming test (FST). We measured the expression of D1Rs, D2Rs, total DARPP-32, phospho-Thr34 or Thr75-DARPP-32 using Western blotting. The defeated mice showed increased anxiety- and depression-like behaviors, and impaired cognition. No significant differences in D1Rs and D2Rs expression were shown between defeated and control mice in any area studied. A significantly increased expression in total DARPP-32, and phospho-DARPP-32 was observed in the PFC or AMY of defeated mice. These data suggest that alterations in dopaminergic markers may be involved in anxiety- and depression-like behaviors, and cognitive impairment induced by social defeat stress.

Abstract
BACKGROUND Adequate nutrition is needed to ensure optimum growth and development of infants and young children. Although the national economy has developed rapidly during recent decades in China, malnutrition continues to be a major public health problem. The aim of the present study was undertaken to assess the prevalence and risk factors associated with stunting and severe stunting under 3 years old in mid-western rural areas in China. METHODS A community-based cross-sectional survey was carried out in 84 villages in mid-western provinces of China in 2010. A total of 1260 children were selected for nutritional assessment in terms of stunting and severe stunting using the new World Health Organization growth standards. Hierarchical logistic regression was used to examine the risk factors for adverse nutritional status. RESULTS The prevalence of stunting and severe stunting was 27.0% and 13.2% respectively. Hierarchical logistic regression analysis showed that the risk factors for stunted children were province of residence, caregiver's education, child's gender, low birthweight and duration of exclusive breastfeeding (<6 months). The risk factors for severe stunting in children aged 0-36 months were province of residence, caregiver's education and child's gender. CONCLUSIONS These results indicate that malnutrition is still a major public health problem among children under 3 years old. The government should implement appropriate nutritional intervention strategies to help reduce the prevalence of malnutrition in children.

Abstract
Caspase-8 (CASP8), member of the caspase cysteine protease family, plays an important role in cancer development. CASP8 D302H (rs1045485) (D, Aspartate; H, Histidine) and CASP8 -652 6N del (rs3834129) polymorphisms have been reported to be associated with Cancer susceptibility. However, there are many controversies on this issue. Therefore we performed this meta-analysis with 32 publications, which include 25800 case and 31964 control subjects for CASP8 -652 6N del polymorphism, and 36883 cases and 41089 controls for D302H polymorphism. The results demonstrated that the -652 6N del frequency showed significant difference between case and control group (del versus ins: OR=0.92; 95% CI: 0.90-0.95, p<0.00001). Homozygous, dominant and recessive genotypes were significantly associated with cancer risks. For D302H polymorphism, data indicated the association of allele C with decreased cancer risk (Overall, C versus G: OR=0.93; 95% CI: 0.86-0.99, p=0.03). All genetic models also indicated the significant association with cancer risk especially in Asian population. Further subgroup analysis indicated that CASP8 -652 6N del polymorphism was associated with breast cancer, lung and gastrointestinal cancer susceptibility. CASP8 D302H was found to be only associated with breast cancer risk. Therefore, these two CASP8 variations could be regarded as potential biomarkers for cancer risk.

Abstract
BACKGROUND Thymosin β4 (Tβ4) is a 5K actin binding peptide. Tβ4 improves neurological outcome in a rat model of embolic stroke and research is now focused on optimizing its dose for clinical trials. The purpose of this study was to perform a dose-response study of Tβ4 to determine the optimal dose of neurological improvement in a rat model of embolic stroke. METHODS Male Wistar rats were subjected to embolic middle cerebral artery occlusion (MCAo). Rats were divided into 4 groups of 10 animals/group: control, 2, 12 and 18 mg/kg. Tβ4 was administered intraperitoneally 24h after MCAo and then every 3 days for 4 additional doses in a randomized controlled fashion. Neurological tests were performed after MCAo and before treatment and up to 8 weeks after treatment. The rats were sacrificed 56 days after MCAo and lesion volumes measured. Generalized estimating equation was used to compare the treatment effect on long term functional recovery at day 56. A quartic regression model was used for an optimal dose determination. RESULTS Tβ4 significantly improved neurological outcome at dose of 2 and 12 mg/kg at day 14 and extended to day 56 (p-values <0.05). The higher dose of 18 mg/kg did not show significant improvement. The estimated optimal dose of 3.75 mg/kg would provide optimal neurological improvement. CONCLUSIONS This study shown that Tβ4 significantly improved the long term neurological functional recovery at day 56 after MCAo with an optimal dose of 3.75 mg/kg. These results provide preclinical data for human clinical trials.

Abstract
People who suffer from traumatic brain injury (TBI) often experience cognitive
deficits in spatial reference and working memory. The possible roles of
cyclooxygenase-1 (COX-1) in learning and memory impairment in mice with TBI are far
from well known. Adult mice subjected to TBI were treated with the COX-1 selective
inhibitor SC560. Performance in the open field and on the beam walk was then used to
assess motor and behavioral function 1, 3, 7, 14, and 21 days following injury.
Acquisition of spatial learning and memory retention was assessed using the Morris
water maze on day 15 post-TBI. The expressions of COX-1, prostaglandin E2 (PGE2),
interleukin (IL)-6, brain-derived neurotrophic factor (BDNF), platelet-derived growth
factor BB (PDGF-BB), synapsin-I, and synaptophysin were detected in TBI mice.
Administration of SC560 improved performance of beam walk tasks as well as spatial
learning and memory after TBI. SC560 also reduced expressions of inflammatory markers
IL-6 and PGE2, and reversed the expressions of COX-1, BDNF, PDGF-BB, synapsin-I, and
synaptophysin in TBI mice. The present findings demonstrated that COX-1 might play an
important role in cognitive deficits after TBI and that selective COX-1 inhibition
should be further investigated as a potential therapeutic approach for TBI.

Abstract
Peroral endoscopic myotomy (POEM) has been developed as a minimally invasive endoscopic treatment for achalasia for years. However, the optimal length of submucosal tunnel and myotomy of muscle bundles during procedure of POEM has not yet been determined, so we aim to assess safety and efficacy of modified POEM with shorter myotomy of muscle bundles in achalasia patients. Consecutive achalasia patients had been performed modified POEM with shorter myotomy, and assessed by symptoms, high-resolution manometry, and barium swallow examinations before and 3 months after POEM for safety and efficacy evaluation. Modified POEM with shorter submucosal tunnel (mean length 6.8 cm) and endoscopic myotomy of muscle bundles (total mean length 5.4 cm) were completed in 46 consecutive achalasia patients. During the 3-month follow up in all cases, significant improvement of symptoms (a significant drop in the Eckardt score 8.4 ± 3.2 vs. 2.7 ± 1.9; P < 0.001), decreased lower esophageal sphincter pressure (39.4 ± 10.1 vs. 24.4 ± 9.1 mmHg; P < 0.001) and integrated relaxation pressure (38.6 ± 10.4 vs. 25.7 ± 9.6 mmHg; P < 0.01), and a drop in height of esophagus barium-contrast column (5.4 ± 3.1 vs. 2.6 ± 1.8 cm; P < 0.001) were observed. The frequencies of adverse events were lower in those under endotracheal anesthesia and CO2 insufflations compared with intravenous anesthesia and air insufflations. Only three patients were found to have gastroesophageal reflux disease on follow up. Modified POEM with shorter myotomy under endotracheal anesthesia and CO2 insufflations shows its good safety and excellent short-term efficacy in the treatment of achalasia. But further studies are warranted to assess the long-term efficacy.

Abstract
Hyperandrogenemia is associated with insulin resistance and type 2 diabetes in women with polycystic ovary syndrome raising the possibility that androgen receptor signaling pathway plays an important role in the development and progression of β-cell dysfunction. Testosterone is the major circulating androgen in women. In this study, we investigated the effect of testosterone on INS-1 cells to find whether excess androgen could produce endoplasmic reticulum (ER) stress thereby contributing to β-cell dysfunction. The role of testosterone in INS-1 cell apoptosis was detected by flow cytometry and electron microscopy. Expression of BIP, ATF4, and CHOP were assessed by RT-PCR and Western blot. Testosterone/AR could not only initiate cell apoptosis but also induce the activation of eukaryotic initiation factor 2 alpha (eIF2α) cascades in INS-1 cells. Treatment of ER stress inhibitor or flutamide (AR inhibitor) could inhibit testosterone-induced cell apoptosis and CHOP expression. These results suggest that testosterone/AR pathway caused INS-1 cell apoptosis was at least in part through eIF2α/CHOP cascades.
