Abstract
Objective: To analyze the risk factors of stillbirth in third trimester. Methods: Clinical data of 649 cases of stillbirth in third trimester were analyzed retrospectively in 22 hospitals of Haidian district from October 2011 to September 2016, including the incidence, the maternal profile, the perinatal care during pregnancy and the causes of stillbirth. Results: (1) The incidence of stillbirth in third trimester in Haidian district from October 2011 to September 2016 was 0.293%(649/221 845). While the incidence in floating pregnant women (0.349%, 342/97 939) was higher than that in the residence (0.248%, 307/123 906), with statistically significant difference (χ(2)=19.178, P<0.01). The incidence of stillbirth in multiple pregnancy(0.201%, 89/4 264) was higher than that in singleton pregnancy (0.257%, 560/217 581), with statistically significant difference(χ(2)=4.690, P<0.01). There was no statistically significant difference in the incidence of stillbirth between male (0.300%, 347/115 632) and female fetuses (0.284%, 302/106 205; χ(2)=0.467, P>0.05).(2)Among the 649 cases, the floating population accounted for the majority of those who never had prenatal visit (84.0%, 21/25), or less than 5 visits (80.7%, 125/155), or the first visit was beyond 13 gestational weeks(66.0%, 165/649). The causes of stillbirth in order were fetal factors (30.7%, 199/649), maternal factors(28.0%, 182/649), umbilical cord factors (20.0%, 130/649), unexplained factors (17.6%, 114/649) and placental factors (3.7%, 24/649). Birth defects, pregnancy hypertensive disorders, umbilical cord entanglement or torsion were the most important factors, accounting for 22.8%(148/649), 17.4%(113/649), 17.3%(112/649), respectively. Conclusions: The floating pregnant women are key population of stillbirth in third trimester. Maternal care and education should be strengthened in this population. The prevention of birth defect, better prenatal care in women with complications, and close monitor during labor are the key measures to reduce the incidence of stillbirth in third trimester.

Abstract
Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion: In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.

Intracellular mature IL-37 suppresses tumor metastasis via inhibiting Rac1 activation. Oncogene 2017; 37:1095-1106.

Abstract
IL-37, a newly found anti-inflammatory cytokine of the IL-1 family, has both extracellular and intracellular functions. Accumulating evidences indicate that it is also involved in tumor progression. However, the mechanism and its intracellular target are unclear. In this study, clinical data from 84 patients showed that loss or reduced expression of IL-37 in lung adenocarcinoma tissues was significantly associated with tumor metastasis. We further provided evidence that IL-37 inhibited effectively tumor metastasis in vitro and in vivo. Moreover, we uncovered a novel mechanism by which IL-37 suppressed tumor cell migration via its intracellular mature form (amino acids 46-218). Intracellular mature form of IL-37, but not its extracellular form, markedly inhibited migration of multiple kinds of tumor cells through inhibiting Rac1 activation. Mechanistically, intracellular mature IL-37 directly bound to the CAAX motif in the C-terminal hypervariable region of Rac1, and then inhibited Rac1 membrane translocation and subsequent downstream signaling. Our research identifies intracellular mature IL-37 as a novel endogenous inhibitor of Rac1. Given the crucial roles of Rac1 in tumor angiogenesis and metastasis, intracellular mature IL-37 might serve as a potential strategy for the control of Rac1 activity and tumor progression.

Abstract
Merging neutron stars offer an excellent laboratory for simultaneously studying strong-field gravity and matter in extreme environments. We establish the physical association of an electromagnetic counterpart (EM170817) with gravitational waves (GW170817) detected from merging neutron stars. By synthesizing a panchromatic data set, we demonstrate that merging neutron stars are a long-sought production site forging heavy elements by r-process nucleosynthesis. The weak gamma rays seen in EM170817 are dissimilar to classical short gamma-ray bursts with ultrarelativistic jets. Instead, we suggest that breakout of a wide-angle, mildly relativistic cocoon engulfing the jet explains the low-luminosity gamma rays, the high-luminosity ultraviolet-optical-infrared, and the delayed radio and x-ray emission. We posit that all neutron star mergers may lead to a wide-angle cocoon breakout, sometimes accompanied by a successful jet and sometimes by a choked jet.

Abstract
Trisomy 8 in myelodysplastic syndrome (MDS) plays an important role in concurrent intestinal Behçet's disease (BD) pathogenesis. Here, we reported a case of intestinal BD combined with MDS involving trisomy 8. A 48-year-old woman who has had a 20-year history of recurrent oral ulcer, perineal ulcer and iris, was diagnosed as MDS with trisomy 8 four years ago. She developed high fever and acute abdominal pain. Multiple ulcerative perforations in ileum and colon were found by endoscopy, meeting the criteria for intestinal BD. The patient was successfully treated with immunomodulatory drugs.

Abstract
Objective: To estimate the prevalence of anxiety and depression symptoms during pregnancy among women from six districts of China and to explore the determinants of anxiety and depression during pregnancy. Methods: A cross-sectional study of maternal health status was conducted using the probability proportionate to size sampling method among pregnant women from six counties/districts in six provinces of China (Hebei, Liaoning, Fujian, Hunan, Sichuan and Yunnan). A questionnaire was completed by each of the women included in the study from August to December 2014. Women were recruited from three medical and health institutions with the most obstetrics patients in each district. A total of 4 210 pregnant women were included in the investigation. The hospital anxiety and depression (HAD) scale was applied to measure the symptoms of anxiety and depression in the pregnant women. Trend chi square test was used to assess the differences of anxiety and depression symptom among three trimesters. The multivariate logistic regression model was used to investigate potential contributory factors. Results: The detection rates for anxiety symptoms and depression symptoms during pregnancy were 8.5% (357/4 210) and 12.5% (525/4 210), respectively. The prevalence of anxiety symptoms during the first, second and third trimesters were 7.9% (110/1 392), 8.8% (124/1 413) and 8.8% (123/1 405), respectively (χ2trend=0.89, P= 0.419). The prevalence of depression symptoms during the first, second and third trimesters were 14.0% (195/1 392), 12.6% (178/1 413) and 10.8% (152/1 405), respectively (χ2trend=6.52, P=0.011). Multivariate logistic regression analysis showed an increased risk of anxiety and depression in women with an educational background of middle school rather than a college degree (OR=1.94, 95% CI: 1.44-2.63; OR=3.80, 95% CI: 2.45- 5.91). Furthermore, compared with planned pregnancies, women with unplanned pregnancies had a higher risk of anxiety and depression (OR=1.33, 95% CI: 1.06- 1.66; OR=1.35, 95% CI: 1.07- 1.71). Pregnant women who felt they lived in crowded residential conditions were at an increased risk of anxiety compared with those living in spacious residential environments (OR=1.82, 95% CI: 1.15- 2.87). Pregnant women with a household income of less than 10 000 yuan were at a higher risk of depression than living in a household with an income of ≥100 000 yuan (OR=1.91, 95% CI: 1.05-3.49). Similarly, multiparous women (≥2) were at higher risk of depression compared with nulliparous women (OR=1.88, 95% CI: 1.04- 3.41). Conclusion: The prevalence of anxiety and depression symptoms during pregnancy appears to be associated with several demographic factors, along with a women's obstetrical history. Lower educational background, unplanned pregnancy, the feeling of living under crowded residential conditions were all found to be risk factors for anxiety during pregnancy. Similarly, lower educational background, unplanned pregnancy, a lower household income (<10 000) and a greater number of previous deliveries were all risk factors for depression during pregnancy.

Abstract
Objective: To analyze clinical feature and treatment outcome of young patients with high-risk diffuse large B cell lymphoma. Methods: A total of 122 young patients with high-risk diffuse large B cell lymphoma who were treated in Third Hospital of Peking University during the period from January 2000 to April 2015 were retrospectively analyzed, and the clinical features, laboratory data were included in Kaplan-Meier and prognostic analysis. Results: In our center, the incidence of young high-risk DLBCL was 27.1% in all DLBCL patients, median age was 44.0 years, 99.2% patients belong to Ⅲ and Ⅳstage, 50% patients had more than two extranodal organs involvement, and the higher proliferation index(Ki-67≥80%) was present in 63.1% of patients, Immunohistochemistry showed that 36.7% patients in 30 cases were double-expressed DLBCL. The overall response rate(ORR) for the whole group was 79.4%, the complete response rate was 39.7% , the 3, 5-year progression free survival rate was 59.8% and 57.0%, the 3, 5-year overall survival rate was 63.5% and 57.8%, respectively. 44.3% patients were refractory-relapsed DLBCL. Rituximab can improve the survival of patients and 3-year overall survival rate was 75.2% vs 46.1%(P=0.001). High-dose chemotherapy was superior to CHOP regimen which 3-year overall survival rate was 84.6% vs 54.1%(P=0.006). Compared with chemotherapy group , auto-hematopoietic stem cell transplantation can improve prognosis of patients and 3-year overall survival rate was 93.4% vs 48.3%(P<0.001). The level of Ki-67, B symptom, ECOG score, the level of LDH, WBC and albumin, ESR level, anemia, rituximab therapy, initial regimens, ASCT, initial treatment outcome and refractory-relapsed were predictive of overall survival. Multivariate analysis indicated that albumin level(RR=5.462, P=0.019), initial treatment outcome(RR=34.863, P<0.001) and refractory-relapsed (RR=24.374, P<0.001)were independent prognostic risk factors. Conclusions: Young patients with high-risk DLBCL were highly aggressive in clinical and pathological features . Rituximab and high-dose regimens can improve the survival of patients.

Abstract
The characteristics of the surface inactive layer of a 1-kg-mass p-type point-contact germanium detector were studied. The thickness of the inactive layer and its uniformity on the top and lateral surfaces were measured. A charge collection efficiency function was developed according to the Monte Carlo simulation to describe the charge collection capacity along the depth within this inactive layer. In the energy range below 18keV, the surface, bulk, and total spectra of 57Co, 133Ba, 137Cs, and 60Co from simulations based on the charge collection efficiency function were well consistent with those from experiments.

Abstract
Telbivudine, an FDA pregnancy category B drug, has been found to reduce hepatitis B virus (HBV) perinatal transmission with no safety concerns in infants aged up to 1 year. This study evaluated the long-term efficacy and safety of telbivudine in 214 infants born to 210 pregnant women with chronic hepatitis B infection who were treated with telbivudine during pregnancy (weeks 20-32 of gestation). The infants were followed for up to 5 years after birth. The efficacy endpoint was the rate of perinatal transmission, which was established by HBsAg and HBV DNA levels at 7 and 12 months. Safety endpoints included head circumference, weight, height, congenital abnormality and hospitalization rates. In addition, the Denver Developmental Screening Test was performed in 92 randomly selected infants. None of the 214 infants born to these women were infected with HBV, and all had effective serum hepatitis B surface antibody (HBsAb) levels. Compared with Chinese standard values, there were few differences in the infants' mean head circumference, weight, and height values. No birth defects were diagnosed, and the congenital abnormality rate was 0.934%. Serious adverse events requiring hospitalization occurred in 20 infants (9.35%). The qualified Denver Developmental Screening Test rate in 92 infants was 97.82%, which was comparable to a rate of 92% in normal Chinese children. Thus, treatment with telbivudine during the second or third trimesters of pregnancy safely blocked perinatal transmission of HBV. Infants born to telbivudine-treated mothers showed normal growth and development during long-term follow-up of up to 5 years.

Abstract
BACKGROUND Aberrant activation of β-catenin signaling by both WNT-dependent and WNT-independent pathways has been demonstrated in asthmatic airways, which is thought to contribute critically in remodeling of the airways. Yet, the exact role of β-catenin in asthma is very poorly defined. As we have previously reported abnormal expression of β-catenin in a toluene diisocyanate (TDI)-induced asthma model, in this study, we evaluated the therapeutic efficacy of two small molecules XAV-939 and ICG-001 in TDI-asthmatic male BALB/c mice, which selectively block β-catenin-mediated transcription. METHODS Male BALB/c mice were sensitized and challenged with TDI to generate a chemically induced asthma model. Inhibitors of β-catenin, XAV-939, and ICG-001 were respectively given to the mice through intraperitoneally injection. RESULTS TDI exposure led to a significantly increased activity of β-catenin, which was then confirmed by a luciferase assay in 16HBE transfected with the TOPFlash reporter plasmid. Treatment with either XAV-939 or ICG-001 effectively inhibited activation of β-catenin and downregulated mRNA expression of β-catenin-targeted genes in TDI-asthmatic mice, paralleled by dramatically attenuated TDI-induced hyperresponsiveness and inflammation of the airway, alleviated airway goblet cell metaplasia and collagen deposition, decreased Th2 inflammation, as well as lower levels of TGFβ1, VEGF, HMGB1, and IL-1β. CONCLUSION The results showed that β-catenin is a principal mediator of TDI-induced asthma, proposing β-catenin as a promising therapeutic target in asthma.

Abstract
Objective: To investigate the effect of optical zone diameter on corneal biomechanical properties after small incision lenticule extraction (SMILE). Methods: In this prospective case-control study, 62 eyes of 42 patients with myopia and myopic astigmatism that had undergone SMILE procedure were divided into 2 groups according to the optical zone (OZ) diameter: group A, 31 eyes of 19 patients, OZ= 6.5 mm; group B, 31eyes of 23 patients, OZ=6.0 mm. These patients were examined for corneal hysteresis (CH) and corneal resistance factor (CRF) with the Ocular Response Analyzer (ORA) preoperatively and at 1 week, 1 month and 3 months postoperatively; at the same time, the central corneal thickness-corrected indices of DifCH and DifCRF were calculated. Pearson correlation was applied to analyze the correlation between CH and CRF and central corneal thickness. Independent-samples t test was utilized to compare CH and CRF between the two groups. Repeated ANOVA was used to compare the difference of corneal biomechanical properties at different follow-up timepoints. Results: The preoperative mean CRF and CH values were (10.13±1.19) mmHg and (9.65±1.12) mmHg in group A and (10.34±0.89) mmHg and (10.04± 1.05) mmHg in group B, respectively, and no significant differences were found in CRF and CH between the two groups (CRF: t=-0.807, P=0.423. CH: t=-1.405, P=0.165). The mean CRF values in group A at postoperative 1 week and 3 months were (6.62 ± 1.09) mmHg and (6.83 ± 1.07) mmHg, respectively, which were significantly lower than the relevant mean CRF values in group B (t=-2.703, P=0.009. t=-3.733, P= 0.001). Meanwhile, the mean CH values at 1 week, 1 month and 3 months postoperatively in group A were (7.31±1.06) mmHg, (7.37±0.96) mmHg and (7.82±0.97) mmHg, respectively, which were significantly lower than those in group B (t=-2.415, P=0.019. t=-2.113, P=0.039. t=-2.67, P=0.01). Moreover, the DifCRF and DifCH values in group A were significantly lower than those in group B at 3 months postoperatively (t=-3.409, P=0.001. t=-2.064, P=0.044). The CRF and CH values in both groups showed a significant reduction at 1 week, 1 month and 3 months postoperatively (P<0.05). Conclusions: The size of optical zone has some effects on corneal biomechanical properties after SMILE. The smaller optical zone diameter has a relatively smaller effect.

Abstract
Abstract
Cancer cell lines (CCLs) serve as models to study the functional consequences of the genomic lesions in patients and as screening platforms for prediction of drug response. While genomic and transcriptomic data have proven to be useful predictors, the ability of these omics platforms to predict protein level and function is limited. Furthermore, since proteins are the targets of the majority of the targeted therapies, protein levels and importantly protein function would be expected to provide more powerful predictions than DNA or RNA data. While large scale genomic and transcriptomic data linked to drug sensitivity are available for over a thousand CCLs, proteomic data is available for only a small subset of lines. Here we performed proteomic profiling of 736 cell lines using reverse-phase protein arrays (RPPAs) with approximately 300 antibodies providing an unbiased sparse representation of the majority of signaling pathways.
The functional proteomic analysis revealed 10 protein-based clusters across all cell lines. Similar to human tumors, the breast cell lines fell into three major clusters representing basal-like, luminal/Her2-amplified and claudin-low breast cancer subtypes. The basal-like and claudin-low clusters contained all of the representative breast cancer cell lines as well as a much larger number of other CCLs. For example, the 6 claudin-low breast cancers analyzed reside in an EMT cluster, in which only 8/126 are breast cell lines. However, the complete cluster including multiple non-breast cancer cell lines recapitulated mRNA and protein features of claudin-low breast tumors, including a high EMT signature and low level of hormone receptor pathway activity. We thus explored whether we could gain power for linking the limited number of basal and claudin-low breast cancer cell lines to therapeutic sensitivity by assessing patterns of drug sensitivity in each cluster for both the breast and non-breast cancer cell lines in the cluster. We explored drug sensitivity of 481 therapeutic compounds from the Cancer Therapeutic Response Portal (CTRP v2) and demonstrated that the non- breast cancer and breast cancer cell lines in each cluster provided similar patterns of drug sensitivity. For example, Claudin-low/EMT cell lines of both breast cancer and non-breast cancer origin showed decreased sensitivity to PI3K/mTOR inhibitors compared to luminal breast cancers (p<0.05 for 4 mTOR inhibitors) and drugs targeting EGFR family compared to basal cell lines (p<0.05 for 7 EGFR/ERBB2 inhibitors). Thus it is possible to gain information by characterizing cell lines with similar patterns of protein expression and provide important information related to drug sensitivity of uncommon breast cancer lineages. The functional proteomic analysis provides a wealth of information that complements the genomic and transciptomic studies of cancer cell lines, and demonstrates the opportunity to leverage cell line 'pan-cancer' proteomic patterns to improve characterization of specific breast cancer subtypes. To facilitate broad access to these data, we developed a user-friendly data portal, the MD Anderson Cell Lines Project (MCLP), that provides both data analysis and download (http://ibl.mdanderson.org/mclp/).

Abstract
Abstract
BACKGROUND: Patients with HER2 negative primary tumors of ≥25 mm were treated with neoadjuvant chemotherapy (4 x FEC100 + 12 weeks of taxane-based therapy) and randomized (1:1) to receive bevacizumab or not. Mammography, ultrasound and MR imaging were used for response evaluation, in addition to the final pathology assessment after surgery.
HYPOTHESIS: RPPA proteomic analyses support identification of molecular mechanisms associated with clinical response to bevacizumab treatment.
METHODS: Tumor responses were evaluable in 132 patients; of which 66 received bevacizumab. Ratio of the tumor size at final pathology assessment, and at inclusion was calculated to obtain a continuous scale of response reflecting the percentage of tumor shrinkage in response to therapy. Tumor material was obtained at screening, 12 weeks into treatment and at surgical removal of tumors at 25 weeks. Lysates from each sample was analyzed on reverse phase protein arrays (RPPA) for expression levels of 210 proteins of which 54 were phospho-specific.
RESULTS: Several proteins were found for which expression prior to treatment reflected a better response on tumor shrinkage in the combination treatment arm (chemotherapy+bevacizumab). The proteomic response from week 0 to 12 in both treatment arms had an overall similar profile regarding up- and down-regulated proteins; however, the combination treatment (FEC100 + bevacizumab) induced a more pronounced effect on regulation of each protein. This might reflect the capability of bevacizumab therapy to potentiate the effects of the anthracyclin based chemotherapy from week 0 to 12. Conversely, from week 12-25 (taxane-based therapy + bevacizumab) this effect was lost or even reversed, except for certain phosphoproteins where potentiation imposed by bevacizumab was sustained throughout the whole treatment period. We are in the process of analyzing the impact of phosphorylation and thus protein activation states on treatment response. Furthermore, tumors with low hormone receptor pathway score demonstrated a better response in the combination treatment (chemotherapy+bevacizumab). Additionally, in these good responders the hormone signaling pathway was significantly upregulated during treatment. Further investigations are conducted to determine if this was due to selective ablation of hormone receptor negative tumor cells, or a re-programming of the molecular phenotype of cells present prior to treatment. The above mentioned results have potentially important clinical relevance and will be further investigated with respect to subtypes and the biological pathways affected by antiangiogenic therapy.

Abstract
Multi-functional nanomaterials possess unique properties, facilitating both therapeutic and diagnostic applications among others. Herein, we developed dual-functional lipid-like nanoparticles for simultaneous delivery of mRNA and magnetic resonance imaging (MRI) contrast agents in order to express functional proteins and provide real-time visualization. TT3-Gd18 LLNs were identified as a lead formulation, which was able to encapsulate 91% of mRNA and 74% of Gd. This formulation showed a comparable or a slightly higher delivery efficiency of mRNA compared to the initial TT3 LLNs. Moreover, a strong MRI signal was observed in the cell pellets treated with TT3-Gd18 LLNs. More importantly, TT3-Gd18 LLNs demonstrated an efficient delivery of mRNA and Gd contrast agents in vivo.

Abstract
BACKGROUND Acting as a proto-oncogene, long noncoding RNAs (lncRNAs) urothelial carcinoembryonic antigen 1 (UCA1) plays a key role in the occurrence and development of several human tumors. However, the expression and biological functions of UCA1 in glioma are less known. This study discussed the expression of UCA1 in glioma and its effect on the proliferation and cell cycle of glioma cells. METHOD LncRNA UCA1 expressions in 64 glioma samples (Grade I-II in 22 cases and Grade III-IV in 42 cases, according to WHO criteria) and 10 normal brain samples were detected using real-time fluorescence quantitative PCR. On this basis, the correlations of UCA1 to clinicopathological characteristics and prognosis of glioma were assessed. Then, using qPCR, the lncRNA UCA1 expressions in glioma cell lines and astrocytes were detected. UCA1-overexpressing glioma cell lines U87 and U251 were further detected after siRNA transfection of these two cell lines, and the impact on cell proliferation and cell cycle was assessed with CCK-8 (cell counting kit-8) assay and flow cytometry method (FCM), respectively. The expression of cyclin D1, a cell cycle-related protein, was detected using Western Blot. RESULT LncRNA UCA1 expression in the glioma samples was obviously higher as compared with the normal brain samples (P < 0.001), and the expression was correlated significantly with grading of the tumors (P < 0.05). However, lncRNA UCA1 expression was not correlated with age, gender, tumor size and KPS score (P > 0.05). After interference of UCA1 expression by siRNA transfection, the proliferation of both U251 and SHG-44 cells was inhibited (P < 0.05), with more cells arrested in G0/G1 (P < 0.05). Moreover, cyclin D1 expression was also downregulated considerably. CONCLUSION LncRNA UCA1 can promote the proliferation and cell cycle progression of glioma cells by upregulating cyclin D1 transcription. So UCA1 may serve as an independent prognostic indicator and a novel therapeutic target for glioma.

Abstract
In this study, a facile two-phase solvothermal method was used to synthesize Co3O4 nanocubes with high crystallinity and narrow size distribution (∼49 nm) for use in lithium-ion batteries. Here, oleylamine (OAm) was chosen as the solvent, surfactant, and reducing agent. After washing with the appropriate organic solvent, the Co3O4 nanocubes self-assembled into hexagonal plates with a diameter and thickness of approximately 2.5 μm and 550 nm, respectively. Moreover, with the assistance of dipole-dipole and van der Waals interactions, the Co3O4 nanocubes stacked along the [111] direction with their exposed facets attached, leading to their final exposed cross-sectional facet being (111). A possible assembling mechanism is proposed and explained in detail. Furthermore, the self-assembled (111) faceted Co3O4 plates exhibited superior electrochemical capacity and stability to those original (001) faceted Co3O4 nanocubes for Li+ ion storage. Therefore, the solvent engineered self-assembly into secondary structures has proven to be a potential strategy for energy applications.

Abstract
OBJECTIVES To explore associations of dietary diversity with cognitive function among Chinese elderly. DESIGN This cross-sectional study was conducted in 2011-2012, data were analyzed using multiple linear regression and logistic regression models. SETTING community-based setting in the 23 provinces in China. SUBJECTS 8,571 elderly participants, including 2984 younger elderly aged 65-79 and 5587 oldest old aged 80+ participated in this study. MEASUREMENT Intake frequencies of food groups was collected and dietary diversity (DD) was assessed based on the mean of DD score. Cognitive function was assessed using the Chinese version of Mini-Mental State Examination (MMSE), and cognitive impairment was defined using education-based cutoffs. Information about socio-demographics, lifestyles, resilience and health status was also collected. RESULTS Poor dietary diversity was significantly associated with cognitive function, with β (95% CI) of -0.11(-0.14, -0.08) for -log (31-MMSE score) and odds ratio (95% CI) of 1.29 (1.14, 1.47) for cognitive impairment. Interaction effect of age with DD was observed on cognitive impairment (P interaction=0.018), but not on -log (31-MMSE score) (P interaction=0.08). Further separate analysis showed that poor DD was significantly associated with increased risk of cognitive impairment in the oldest old (p<0.01), with odds ratio (95% CI) of 1.34 (1.17, 1.54), while not in the younger elderly (p>0.05), with OR (95% CI) being 1.09 (0.80, 1.47) in the fully adjusted model. Similar results were obtained when DD was categorized into four groups. CONCLUSIONS Poor dietary diversity was associated with worse global cognitive function among Chinese elderly, and particularly for the oldest old. This finding would be very meaningful for prevention of cognitive impairment.

Abstract
Distant metastasis is the major cause of breast cancer-related mortality, commonly emerging clinically after 5 or more years of seeming 'cure' of the primary tumor, indicating a quiescent dormancy. The lack of relevant accessible model systems for metastasis that recreate this latent stage has hindered our understanding of the molecular basis and the development of therapies against these lethal outgrowths. We previously reported on the development of an all-human 3D ex vivo hepatic microphysiological system that reproduces several features of liver physiology and enables spontaneous dormancy in a subpopulation of breast cancer cells. However, we observed that the dormant cells were localized primarily within the 3D tissue, while the proliferative cells were in contact with the polystyrene scaffold. As matrix stiffness is known to drive inflammatory and malignant behaviors, we explored the occurrence of spontaneous tumor dormancy and inflammatory phenotype. The microphysiological system was retrofitted with PEGDa-SynKRGD hydrogel scaffolding, which is softer and differs in the interface with the tissue. The microphysiological system incorporated donor-matched primary human hepatocytes and non-parenchymal cells (NPCs), with MDA-MB-231 breast cancer cells. Hepatic tissue in hydrogel scaffolds secreted lower levels of pro-inflammatory analytes, and was more responsive to inflammatory stimuli. The proportion of tumor cells entering dormancy was markedly increased in the hydrogel-supported tissue compared to polystyrene. Interestingly, an unexpected differential response of dormant cells to varying chemotherapeutic doses was identified, which if reflective of patient pathophysiology, has important implications for patient dosing regimens. These findings highlight the metastatic microphysiological system fitted with hydrogel scaffolds as a critical tool in the assessment and development of therapeutic strategies to target dormant metastatic breast cancer.

Abstract
UNLABELLED Bone loss after spinal cord injury (SCI) is rapid, severe, and refractory to interventions studied to date. Mice with sclerostin gene deletion are resistant to the severe sublesional bone loss induced by SCI, further indicating pharmacological inhibition of sclerostin may represent a promising novel approach to this challenging medical problem. INTRODUCTION The bone loss secondary to spinal cord injury (SCI) is associated with several unique pathological features, including the permanent immobilization, neurological dysfunction, and systemic hormonal alternations. It remains unclear how these complex pathophysiological changes are linked to molecular alterations that influence bone metabolism in SCI. Sclerostin is a key negative regulator of bone formation and bone mass. We hypothesized that sclerostin could function as a major mediator of bone loss following SCI. METHODS To test this hypothesis, 10-week-old female sclerostin knockout (SOST KO) and wild type (WT) mice underwent complete spinal cord transection or laminectomy (Sham). RESULTS At 8 weeks after SCI, substantial loss of bone mineral density was observed at the distal femur and proximal tibia in WT mice but not in SOST KO mice. By μCT, trabecular bone volume of the distal femur was markedly decreased by 64 % in WT mice after SCI. In striking contrast, there was no significant reduction of bone volume in SOST KO/SCI mice compared with SOST KO/sham. Histomorphometric analysis of trabecular bone revealed that the significant reduction in bone formation rate following SCI was observed in WT mice but not in SOST KO mice. Moreover, SCI did not alter osteoblastogenesis of marrow stromal cells in SOST KO mice. CONCLUSION Our findings demonstrate that SOST KO mice were protected from the major sublesional bone loss that invariably follows SCI. The evidence indicates that sclerostin is an important mediator of the marked sublesional bone loss after SCI, and that pharmacological inhibition of sclerostin may represent a promising novel approach to this challenging clinical problem.

Abstract
The etiology of achalasia remains largely unknown. Considerable evidence reveals that the lower esophageal sphincter dysfunction is due to the lack of inhibitory neurotransmitter, secondary to esophageal neuronal inflammation or loss. Recent studies suggest hydrogen sulfide may act as an inhibitory transmitter in gastrointestinal tract, but study about hydrogen sulfide in human esophagus still lack. The aim of the study was to investigate if hydrogen sulfide synthesis enzymes could be detected in human esophagus and if the synthesis of the endogenous hydrogen sulfide could be affected in achalasia patients. Tissue samples in cardia, lower esophageal sphincter, 2 cm and 4 cm above lower esophageal sphincter were obtained from achalasia patients undergoing peroral endoscopic myotomy. Control tissues in lower esophageal sphincter were obtained from esophageal carcinoma patients. Expression of cystathionine-β-synthase and cystathionine-γ-lyase in lower esophageal sphincter of achalasia patients and control were detected by immunohistochemical staining. In addition, expression of cystathionine-β-synthase and cystathionine-γ-lyase were compared among different parts of esophagus in achalasia patients. Compared with control, the expression of cystathionine-β-synthase and cystathionine-γ-lyase in lower esophageal sphincter of achalasia patients was significantly reduced (χ2 = 11.429, P = 0.010). The expression of cystathionine-β-synthase and cystathionine-γ-lyase were lower in lower esophageal sphincter than that in 2 cm and 4 cm above lower esophageal sphincter, respectively (all P < 0.05). In conclusion, the expression of hydrogen sulfide synthesis enzymes, cystathionine-β-synthase and cystathionine-γ-lyase, can be detected in human esophagus and is reduced in patients with achalasia, which implicates the involvement of the two hydrogen sulfide synthesis enzymes in the pathophysiology of achalasia.

Abstract
Controversy exists on the relationship between serum thyrotropin (TSH) and blood pressure, and only a few prospective studies are available up to now. The study aimed to investigate the association between serum TSH within the reference range and blood pressure through a 5-year follow-up study. A total of 623 subjects with normal TSH were followed up for 5 years, including the measurement of demographic data, blood pressure, height, weight and serum TSH. Finally, 531 subjects were included in this prospective study. Body mass index (BMI), prevalence of hypertension, and systolic and diastolic blood pressure were all higher at follow-up than at baseline. Adjusted for age, gender, smoking status, BMI and homoeostasis model assessment of insulin resistance (HOMA-IR) at baseline, multiple linear regression analyses found no relationship between serum TSH at baseline and levels of blood pressure at follow-up, but the changes in serum TSH levels during follow-up was positively associated with the changes in systolic blood pressure (B=2.134, P<0.05), which became more significant in women but not significant in men. The change of systolic blood pressure in group of TSH increase >0.5 mIU l-1 was significantly higher than in group of TSH decrease >0.5 mIU l-1 within reference, after adjusting for age, gender, smoking status, BMI and HOMA-IR at baseline. This result became more significant in women, but no statistical significance was observed in men. Co-variation with serum TSH levels and blood pressure was observed during 5-year follow-up among people with normal TSH.
