Abstract
Objective: To observe the clinical features and effects of extracorporeal membrane oxygenation (ECMO) in critically ill children with acute fulminant myocarditis (AFM). Methods: A retrospective analysis was performed in pediatric patients with AFM requiring ECMO, from December 2015 to December 2018, who were admitted to the Pediatric Intensive Care Unit (PICU) in Shanghai Children's Hospital. According to whether patient was alive at least 48 hours after weaning, the children were divided into successful weaning group (9 cases) and unsucessful weaning group (3 cases). The factors related to successful ECMO weaning were explored. The changes of clinical and biochemical parameters before and after ECMO treatment in successful weaning group were analyzed. Continuous variables were presented as median (inter quartile range) for abnormal distribution data, and Mann-Whitney U test was used to compare the data. Results: A total of 12 pediatric patients including 4 males and 8 females were enrolled in this study. The median body weight was 20 (17, 36) kg, and the median age was 66 (48, 103) months. Nine cases were successfully weaned from ECMO, and 8 cases survived to discharge, and 4 cases died in the hospital. The median interval between symptoms onset and ECMO establishment was 3.0 (2.2, 4.0) days, the median duration of ECMO support was 120 (68, 152) hours. In the unsuccessful weaning group, patients displayed higher levels of initiallactic acid (LA), higher vasoactive-inotropic score (VIS), and longer QRS duration before ECMO establishment when compared with those in the successful weaning group (all P<0.05). After ECMO establishment, mean arterial pressure (MAP), systemic central venous oxygen saturation, LA, myocardial injury markers and left ventricular ejection fraction were all significantly improved in the successful weaning group (all P<0.05). Conclusion: In pediatric AFM patients, serum LA level, VIS and QRS duration before ECMO establishment are associated with successful ECMO weaning.

Abstract
The development of new materials for separating ethylene (C2H4) from ethane (C2H6) by adsorption is of great importance in the petrochemical industry, but remains very challenging owing to their close molecular sizes and physical properties. Using isoreticular chemistry in metal-organic frameworks (MOFs) enables the precise design and construction of target materials with suitable aperture sizes and functional sites for gas separations. Herein, it is described that fine-tuning of pore size and π-complexation simultaneously in microporous copper(I)-chelated MOFs can remarkably boost the C2H4/C2H6 adsorption selectivity. The judicious choice of organic linkers with a different number of carboxyl groups in the UiO-66 framework not only allows the fine tuning of the pore size but also immobilizes copper(I) ions onto the framework. The tailor-made adsorbent, CuI@UiO-66-(COOH)2, thus possesses the optimal pore window size and chelated Cu(I) ions to form π-complexation with C2H4 molecules. It can rapidly adsorb C2H4 driven by the strong π-complexation interactions, while effectively reducing C2H6 uptake due to the selective size-sieving. Therefore, this material exhibits an ultrahigh C2H4/C2H6 selectivity (80.8), outperforming most previously described benchmark materials. The exceptional separation performance of CuI@UiO-66-(COOH)2 is validated by breakthrough experiments for 50/50 v/v C2H4/C2H6 mixtures under ambient conditions.

Abstract
Objective: To report the clinical features and surgical treatment of orbitotemporal neurofibromatosis. Methods: It was a retrospective case series study. The clinical records of 24 patients who were treated for orbitotemporal neurofibromatosis between April 2007 and July 2017 at Beijing Tongren Hospital, Capital Medical University were analyzed. Data collected included sex, age, laterality, periorbital deformities, surgical treatment, follow-up time, complication and recurrence. Results: Sixteen males and 8 females were included. Age at surgery was (15±7) years (4-30 years). All patients were unilaterally involved. Twenty-three patients (96%) had upper lid involvement and ptosis. Nine patients (38%) had lower lid involvement. Fourteen patients (58%) had lateral canthal disinsertion. Three patients (13%) had brow involvement, 10 patients (42%) had conjunctival involvement and 2 patients (8%) had lacrimal gland infiltration. All patients had tumor debulking procedure. Twenty-two patients (92%) had correction of ptosis. Fourteen patients (58%) required lid reconstruction and lateral canthus reattachment surgery. Three patients (13%) had correction of brow ptosis.One patient (4%) had skull and orbit reconstruction. The median follow-up time was 3.5 (1.0-10.0) years. All patients had improved appearance. Ptosis recurred in 6 patients, but were corrected with surgery. On the last follow-up, 7 patients were free of ptosis. In 14 patients, mild ptosis was noted, but the upper lid did not cover the pupil. In 2 patients the pupil was half covered. Only in 1 patient who had not received ptosis correction surgery the pupil was covered completely. Conclusions: The periorbital deformities of orbitotemporal neurofibromatosis include upper eyelid infiltration with ptosis, lateral canthal disinsertion and infiltration of lower eyelid, brow, conjunctiva and lacrimal gland. The appearance of patients with orbitotemporal neurofibromatosis can be significantly improved through oculoplastic surgery. (Chin J Ophthalmol, 2019, 55: 828-833).

Abstract
UNLABELLED We previously found that population-based postfracture notification, which informed primary care physicians of their patient's recent fracture and suggested assessment for osteoporosis, led to an improvement in postfracture care in the context of a randomized controlled trial ( ClinicalTrials.gov identifier NCT00594789, fractures from late 2007 to mid-2010). Since June 2010, a province-wide postfracture notification program was implemented. This study was to (1) determine whether this program has resulted in sustained improvement in postfracture care and (2) test factors associated with receiving osteoporosis care. METHODS A retrospective matched cohort study was performed using population-based health administrative data in Manitoba, Canada. We selected individuals aged 50+ years with an incident major osteoporosis fracture (MOF; N = 18,541) in fiscal years 2000/2001 to 2013/2014 and controls without a MOF (N = 92,705) matched (5:1) on age, sex, and residential area. The Cochran-Armitage test tested for a linear trend in osteoporosis care outcomes for cases and controls. Logistic regressions were used to test characteristics associated with the likelihood of receiving osteoporosis care. RESULTS The percentage of individuals receiving DXA testing and/or osteoporosis medication increased in fracture cases (p < 0.001), but decreased in controls (p < 0.001). Odds ratios for osteoporosis care in years following the postfracture notification program were approximately double of those prior to the clinical trial. In addition to prior MOF (OR 9.03, 95% CI 8.60-9.48), factors associated with osteoporosis care included lower income (OR 0.72, 95% CI 0.67-0.78), glucocorticoid use (OR 4.37, 95% CI 3.72-5.14), diabetes diagnosis (OR = 0.74, 95% CI 0.68-0.80), and Charlson Comorbidity Index (indexes 1-2: OR 1.27, 95% CI 1.20-1.34; indexes 3-5: OR 1.26, 95% CI 1.13-1.40). CONCLUSIONS Adopting a population-based postfracture notification program led to sustained improvements in postfracture care.

Abstract
OBJECTIVE This study aimed to investigate the role of NEDD9 (neural precursor cell expressed developmentally down-regulated 9), BCAR1/P130CAS (BCAR1/P130 Crk-associated substrate) and paxillin in predicting the prognosis of endometrioid adenocarcinoma (EA), so as to guild the nursing of EA. PATIENTS AND METHODS A total of 65 patients who visited Affiliated Hongqi Hospital of Mudanjiang Medical University between June 2015 and June 2017 were enrolled. They underwent gynecological surgery and had their EA confirmed by pathology, and they were assigned to the EA group. All EA tissues were sampled and archived in paraffin blocks. In addition, 40 specimens of atypical endometrial hyperplasia (EAH) (the EAH group) and 40 specimens of normal proliferative endometria with benign uterine fibroids (the EN group) were selected as controls. The protein levels of NEDD9, BCAR1/P130CAS, and paxillin in each group were then detected by immunohistochemical staining. RESULTS The expression of the three proteins in the EA group and EAH group was significantly higher than that in the EN group, and their expression was significantly correlated with the clinical stage, histological grade and lymph node metastasis of EA. In addition, the expression of NEDD9, BCAR1/P130CAS, and paxillin in the EA group was positively correlated with each other. CONCLUSIONS BCAR1/P130CAS and paxillin interact with NEDD9 to participate in the growth and migration of EA cells. Therefore, their proteins can be used as biomarkers for the diagnosis, treatment, and prognosis of EA.

Abstract
Sonic hedgehog (Shh) in dental epithelium regulates tooth morphogenesis by epithelial-mesenchymal signaling transduction. However, the action of Shh signaling regulation in this process is not well understood. Here we find that mesenchymal Suppressor of Fused (Sufu), a major negative regulator of Shh signaling, plays an important role in modulating the tooth germ morphogenesis during the bud-to-cap stage transition. Deletion of Sufu in dental mesenchyme by Dermo1-Cre mice leads to delayed development of mandibular molar into cap stage with defect of primary enamel knot (EK) formation. We show the disruption of cell proliferation and programmed cell death in dental epithelium and mesenchyme in Sufu mutants. Epithelial-specific adhesion molecule E-cadherin is evidently reduced in the bilateral basal cells of tooth germ at E14.5. The cells in the presumptive EK, predominantly expressing P-cadherin, appear stratified but fail to condense. Moreover, the transcripts of primary EK marker genes, including Shh, Fgf4, and p21, are significantly decreased compared to controls. In contrast, we find that deficiency of Sufu results in elevation of Shh signaling in mesenchyme, indicated by the significant upregulation of Gli1 and Ptch1. Meanwhile, the expression of Bmp4 and Fgf3, the critical factors of mesenchymal-epithelial induction, is significantly inhibited in dental mesenchyme. Furthermore, the expression of Runx2 experiences a transient decrease at the bud stage. Taken together, these data suggest that mesenchymal Sufu is necessary for tuning the Shh signaling, which may act as an upstream modulator of Bmp4 and Fgf3 to coordinate the interplay between the dental mesenchyme and epithelium of tooth germ.

Abstract
The quantum criticality of an Ising-like screw chain antiferromagnet SrCo_{2}V_{2}O_{8}, with a transverse magnetic field applied along the crystalline a axis, is investigated by ultralow temperature NMR measurements. The Néel temperature is rapidly and continuously suppressed by the field, giving rise to a quantum critical point (QCP) at H_{C_{1}}≈7.03 T. Surprisingly, a second QCP at H_{C_{2}}≈7.7 T featured with gapless excitations is resolved from both the double-peak structure of the field-dependent spin-lattice relaxation rate 1/^{51}T_{1} at low temperatures and the weakly temperature-dependent 1/^{51}T_{1} at this field. Our data, combined with numerical calculations, suggest that the induced effective staggered transverse field significantly lowers the critical fields, and leads to an exposed QCP at H_{C_{2}}, which belongs to the one-dimensional transverse-field Ising universality.

Abstract
The purpose of this study was to explore the effect of Allograft Inflammatory Factor 1 (AIF-1) on the regulation of proliferation of breast cancer cells. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), cell culture and counting, and mass spectrometry were performed. The biologically active high-purity recombinant protein rhAIF-1 was obtained by optimizing the rhAIF-1 protein purification system, and MDA-MB-231 and MDA-MB-361 breast cancer cell lines were used. After adding to the culture medium, rhAIF-1 was found to promote cell proliferation in dose-dependent and time-dependent manners. The purified protein rhAIF-1 was marked with rhodamine and incubated with the cells. Confocal imaging analysis revealed that the foreign protein was localized in the cytoplasm, and rhAIF-1 was unevenly distributed in the cytoplasm. Although AIF-1 accumulates around the nucleus, it can not enter the nucleus, suggesting that other factors might be involved in the regulation of cell proliferation. In order to find the possible interacting protein of rhAIF-1, protein immunoprecipitation technique and mass spectrometry were employed, and it was indicated that ADAM28m was the possible interacting protein of rhAIF-1. The interaction between rhAIF-1 and ADAM28m was validated by immunoprecipitation along with Western blotting. It was found that rhAIF-1 could precipitate ADAM28m protein by immunoprecipitation. The results indicated that IF-1 participates in the development of breast cancer by interacting with ADAM28m and activating downstream signaling pathways. It was concluded that AIF-1 provides a new idea for the molecular mechanism of breast cancer cell proliferation and acts as a new target for the prevention and treatment of breast cancer in the future.

Abstract
The growing evidence shows that LIM and SH3 Domain Protein 1 (LASP1) is a multi-functional protein that plays important role in forming cytoskeleton and prognostic marker in different cancers. LASP1 expression is correlated with the grade, size, and the metastasis of tumor in clinical samples. And the upregulation of LASP1 facilitates tumor cells proliferation, migration, and invasion perhaps through the interaction with cytoskeleton and increased nuclear translocation. The underlying mechanism of LASP1 on tumor is still in the initial stage; therefore, the signaling pathways in various tumors are specifically summarized to deepen the biological understanding of LASP1. This article systematically summarizes the current status of knowledge regarding the contribution of LASP1 in physiological and pathological processes, especially the progress in tumor. This article also gives an emphasized overview of LASP1 on the correlation with tumor microenvironment.

Abstract
Summary
Since the introduction of fiducial inference by Fisher in the 1930s, its application has been largely confined to relatively simple, parametric problems. In this paper, we present what might be the first time fiducial inference is systematically applied to estimation of a nonparametric survival function under right censoring. We find that the resulting fiducial distribution gives rise to surprisingly good statistical procedures applicable to both one-sample and two-sample problems. In particular, we use the fiducial distribution of a survival function to construct pointwise and curvewise confidence intervals for the survival function, and propose tests based on the curvewise confidence interval. We establish a functional Bernstein–von Mises theorem, and perform thorough simulation studies in scenarios with different levels of censoring. The proposed fiducial-based confidence intervals maintain coverage in situations where asymptotic methods often have substantial coverage problems. Furthermore, the average length of the proposed confidence intervals is often shorter than the length of confidence intervals for competing methods that maintain coverage. Finally, the proposed fiducial test is more powerful than various types of log-rank tests and sup log-rank tests in some scenarios. We illustrate the proposed fiducial test by comparing chemotherapy against chemotherapy combined with radiotherapy, using data from the treatment of locally unresectable gastric cancer.

Abstract
Objective: To analyze the treatment effect of patients with glioblastoma (GBM) and explore prognostic factors. Methods: The clinical data of 635 patients diagnosed as GBM at Neurosurgical Oncology Department Ⅳ of Beijing Tiantan Hospital, Capital Medical University from January 2007 to March 2018 were retrospectively reviewed. There were 386 males and 249 females with an age of (48.7±11.8) years (range: 18-75 years). Patients were divided into three groups according to the time of admission: 2007-2010 group(n=174), 2011-2014 group (n=237) and 2015-2018 group (n=224). Kaplan-Meier plot was used to analyze the effects of different treatment periods, treatment schemes and clinical factors on the survival of patients with GBM. Cox proportion hazard regression analysis was used to identify independent prognostic factors. Results: The median progression-free survival (PFS) and overall survival (OS) of patients in 2007-2010 group, 2011-2014 group, 2015-2018 group was 9.0 months (95% CI: 7.5-10.5), 10.0 months (95% CI: 8.8-11.2), 12.0 months (95% CI: 10.7-13.3) and 17.0 months (95% CI: 13.2-20.8), 20.0 months (95% CI: 16.9-23.1), 23.0 months(95% CI: 17.5-28.5), respectively. The PFS and OS of patients improved significantly over the years (χ(2)=9.693, P=0.008 and χ(2)=8.616, P=0.013). Multivariate survival analysis showed that age, extent of resection, radiotherapy and tumor distant dissemination were independent prognostic factors (all P<0.05). Conclusions: With the continuous development of clinical treatment regimen, the therapeutic effect of Chinese GBM patients has improved remarkably. Age, extent of resection, radiotherapy and tumor distant dissemination are independent prognostic factors associated with survival time.

Abstract
The study aimed to explore the underlying molecular mechanisms of CDK2 inhibition in neuroblastoma by bioinformatics analysis. Gene expression profile GSE16480 was downloaded from the Gene Expression Omnibus. The differentially expressed genes (DEGs) were identified from IMR32 between each time point and average expression of all time points. Gene significance was calculated using dSVDsig algorithm of dnet package. Protein-protein interaction (PPI) network was built. Then, integrated with gene significance, a core PPI network was detected by dNetPipeline algorithm in dnet package. Finally, pathway enrichment analysis was performed for genes in network. Totally, 1524 DEGs were identified. CCNA2 (cyclin A2), EXO1 (exonuclease 1), RAD51AP1 (RAD51 associated protein 1), TOP2A (topoisomerase (DNA) II alpha) and CDK1 (cyclin-dependent kinase 1) were selected as DEGs with higher connectivity after PPI network analysis. In the network, CCNA2, CDK1, BUB1B (BUB1 mitotic checkpoint serine/threonine kinase B) and CCNB1 (cyclin B1) were involved in cell cycle pathway. Additionally, CCNB1, CDK1, CCNE2 (Cyclin E2), and RRM2B (ribonucleotide reductase subunit M2B) were involved in p53 signaling pathway. Cell cycle and p53 signaling pathway were closely associated with neuroblastoma after CDK2 inhibition. The DEGs, such as CCNA2, CCNB1, CDK1 and RRM2B may be the potential targets for neuroblastoma.

Abstract
To investigate the effects of EH domain containing protein 2 (EHD2) on clear cell renal cell carcinoma (ccRCC) and provide new insights for the clinical treatment of rental cancer. Forty patients (26 males and 14 females, 62.4 ± 5.7 years old) with ccRCC were selected from January 2015 to December 2016 to serve as research subjects in this study. The EHD2 protein expression in the tumor tissues and adjacent healthy tissues of ccRCC patients were detected by Western Blot assay. The cells of ccRCC cell lines RLC-310 and 786-O were divided into normal control group (control), no-load control group (pLV), EHD2 overexpression group (pLV-EHD2), and EHD2 interference group (pLV-siEHD2). The expression levels of EHD2 protein in each group of cells were detected by western blot. The cell proliferation was detected by Cell Counting Kit-8 (CCK-8) assay. Wound healing assay was performed to check the cell migration ability. Transwell invasion assay was used to detect the cell invasion ability. Cell apoptosis was detected by flow cytometry. The expression level of EHD2 was significantly increased in pLV-EHD2 group and decreased in pLV-siEHD2 group compared with control group and pLV-siEHD2 group, indicating the successfully established EHD2 overexpression cell line and EHD2 RNA interference cell line. EHD2 overexpression enhanced the proliferation, invasion, and migration but inhibited the apoptosis of ccRCC cells, while EHD2 interference showed opposite functions. EHD2 interference can inhibit the development of ccRCC by inhibiting the proliferation, invasion, and migration, and EHD2 can potentially serve as a molecular target for the clinical treatment of ccRCC.

Abstract
Objective: To investigate the feasibility of detecting circulating tumor cells based on capture of heteroploid chromosome cells in peripheral blood of glioma patients. Methods: A total of 88 patients who were considered to suffer from gliomas and 10 healthy volunteers were enrolled in this study during January 2016 to December 2016 at Beijing Tiantan Hospital, from whom 6 ml preoperative blood was collected. Subtraction enrichment (SE)-immunostaining FISH (iFISH) was applied to capture the heteroploid chromosome 8 cells in those samples. Meanwhile, centromere probe 8(CEP-8)-FISH was used to identify aneuploid cells in 10 tumors and 10 brain tissues. Results: Numerous heteroploid chromosome 8 cells were observed in tumors whereas negative result was present in brain tissues (P<0.01). CTC was successfully detected in 90.9% glioma patients, in contrast, only one healthy volunteer was shown with a heteroploid chromosome 8 cell (P<0.01). Glial fibrillary acidic protein was not exhibited in the overwhelming majority of CTC (96.1%). High grade glioma (HGG) without IDH mutation possessed much more CTC than low grade (12.0 vs 2.2), P<0.01. Furthermore, multiploidy (≥5 copies) CTC accounted for a much significant percentage in HGG, either in tumors originating from oligodendrocyte or astrocyte (75.9% vs 56.0%), P<0.01; 62.7% vs 51.7%, P=0.016, respectively). Conclusion: CTC could be identified and enumerated in glioma by detecting aneuploidy cells in blood. The number and multiploidy proportion of CTC may be correlative with tumor grade and molecular characteristics.

Abstract
Objective: To explore the effectiveness and safety of continuous renal replacement therapy (CRRT) combined with extracorporeal membrane oxygenation (ECMO) on rescuing pediatric patients with cardiopulmonary failure. Methods: The medical records of patients treated with ECMO admitted to pediatric intensive care unit (PICU) in Shanghai Children's Hospital from December 2015 to November 2017 were retrospectively extracted. There were 14 patients treated with ECMO combined with CRRT (ECMO+ CRRT group) due to acute kidney injury (AKI) or fluid overload, while 11 cases treated with ECMO only. The demographics and clinical characteristics of patients, the indications, details and complications of ECMO and CRRT support, and the survival rates were analyzed. Results: A total of 25 cases including 15 boys and 10 girls with cardiopulmonary failure treated with ECMO were enrolled in this study, whose median age and body weight were 9 (1-117) months and 10 (2-42) kg. The median duration of ECMO support was 199.2 h, and the median duration of CRRT was 78.6 h. Among the 14 cases in ECMO + CRRT group, 12 cases were treated with CRRT connected to ECMO pipeline, and 2 other cases were treated with independently operated CRRT. The serum level of creatinine was significantly higher in ECMO+ CRRT group than that in ECMO group (53 (22- 126) vs. 29 (12- 92) μmol/L, Z=-2.208, P=0.043). There was no significant difference in running time between ECMO+CRRT group and ECMO group ((257±203) vs. (122± 83) h, t=-2.062, P=0.051). And the incidence of thrombocytopenia was higher in ECMO+CRRT group than that in ECMO group (10/14 vs. 3/11 , χ(2)=4.812, P=0.028). There were no differences in the successful weaning rate and discharge survival rate between ECMO + CRRT and ECMO group (9 vs. 8, χ(2)= 0.203, P= 0.652 and 8 vs. 8, χ(2)= 0.659, P= 0.417, respectively). Conclusion: The combination of CRRT and ECMO is an effective and safe treatment to alleviate fluid overload and improve kidney function in pediatric patients with cardiopulmonary failure.

Abstract
Metal-organic frameworks (MOFs) are organic-inorganic hybrid solids constructed from the coordination interaction of metal ions/clusters with organic linkers, which currently represent one of the most rapidly expanding platforms for new functional materials. Based on well-established approaches, involving tuning the pore sizes, incorporation of functional sites and post-synthetic modification, the pore structures of MOFs can be readily controlled for multifunctional applications. In this brief review, we summarize and highlight our research progresses during our journey on developing functional MOFs for various applications including gas storage, gas separations, luminescent sensing, proton conduction, and molecular recognitions.

Abstract
Objective: To explore the effects of continuous veno-venous hemodiafiltration (CVVHDF) as a rescue therapy in children with Kawasaki disease (KD) complicated with multiple organ dysfunction syndrome (MODS). Methods: The medical records of 5 patients diagnosed as KD with MODS treated with CVVHDF, who were admitted to pediatric intensive care unit (PICU) of Shanghai Children's Hospital from November 2015 to October 2017 were retrospectively collected. The inflammatory factors and parameters of organ function before and after CVVHDF treatment were analyzed. Wilcoxon test was used to compare the changes of parameters before and after CVVHDF treatment. Results: The pediatric critical illness score (PCIS) and the pediatric risk of score mortality score Ⅲ (PRISMⅢ) were 74.0 (70.0, 81.0) and 14.5 (12.5, 17.0), respectively. The duration of CVVHDF treatment was 46.0 (24.5, 48.0) h. The levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), blood lactic acid were significantly decreased after the CVVHDF treatment (0.4 (0.1, 28.8) vs. 142.0 (123.1, 1 454.6) ng/L, Z=-2.023, P=0.043; 0.1 (0.1, 9.3) vs. 1.7(1.1, 30.0) ng/L, Z=-2.023, P=0.043; 1.2(1.1,1.4) vs. 2.5(2.4, 2.7) mmol/L, Z=-2.041, P=0.041 respectively). Moreover, the lung, liver and kidney function were significantly improved as indicated by the ratio of PaO(2) to FiO(2) (380.0 (182.5, 397.5) vs. 160.0 (52.5, 185.0)mmHg (1 mmHg=0.133 kPa), Z=2.041, P=0.041), the level of total bilirubin ((14.9±1.3) vs. (86.4±9.9) μmol/L), and the levels of creatinine (2 cases: 24.0vs. 103.0 μmol/L, 38.0 vs. 142.0 μmol/L). Conclusion: CVVHDF as an adjuvant therapy can rapidly reduce the levels of IL-6 and TNF-α,and improve the organ functions in children with KD complicated with MODS.

Abstract
Background and Materials and methods: In order to clarify and reveal the morphological characteristics of yak placentomes, placentomes obtained from 151 to 180 days of pregnant yaks were observed using light microscopy and scanning and transmission electron microscopy. Results: The results indicated that sessile, dome-shaped yak placentomes seemed to have a relatively complex villous-crypt architecture pattern. There was a straight maternal plate beneath the placentome. Plentiful uterine glands and a dense cellular layer were present in the endometrium lamina propria close to the maternal plate. Trophoblast giant cells appeared to have similar ultrastructure features to these in other ruminants, including abundant mitochondria, an extensive array of rough endoplasmic reticulum, advanced Golgi complex and many specific secretory granules. Trophoblast giant cells could also secrete neutral and acid glycoconjugates. Furthermore, numerous glycoconjugates were distributed in the connective zones between mononuclear trophoblast cells and crypt epithelial cells as well as in maternal connective tissues. Mononucleate trophoblast cells, which had abundant microvilli that interdigitated with the corresponding microvilli arising from the crypt epithelial cells, had numerous mitochondria and vesicles, but there were no glycoconjugates. Conclusions: The morphological structures of yak placentomes were similar to those of other bovid genera; however, certain differences were observed. These findings might provide morphological evidence for evolutionary relationships between different bovid genera.

Abstract
AIMS Because the effect of Cd2+ -immobilized microbe on Cd uptake of plants in Cd-contaminated soil remains underexplored, this study focuses on the effect of Cd2+ -immobilized rhizobia on Cd uptake of soybean. METHODS AND RESULTS Strain KG2 from soybean nodule was identified as Rhizobium pusense KG2 by phylogenetic analysis. Rhizobium pusense KG2 showed the 120 mg l-1 of minimal lethal concentration for Cd2+ . In 50 and 100 mg l-1 of Cd2+ liquid, approximately 2 × 1010 cells removed 56·71 and 22·11% of Cd2+ , respectively. In pot soil containing 50 and 100 mg kg-1 of Cd2+ , strain KG2 caused a 45·9 and 35·3% decrease in soybean root Cd content, respectively. Meanwhile, KG2 improved the root and shoot length, nitrogen content and biomass of soybean plants and superoxide dismutase activity. CONCLUSIONS The Cd2+ -immobilized rhizobia could inhibit soybean plants to absorb Cd2+ from soil, promote plant growth and improve plant's tolerance against Cd. This study is the first time to report that R. pusense is an effective nodulating rhizobium of legume. SIGNIFICANCE AND IMPACT OF THE STUDY Some Cd2+ -immobilized microbe lowering Cd uptake of plant and promoting plant growth should be considered as an effective strategy for producing safety crops in the Cd-contaminated agricultural soil.

Abstract
Objective: To understand the prevalence of HIV infection, syphilis and hepatitis C and related behavioral factors in female sex workers (FSWs) and other 6 risk populations in Tibet Autonomous Region. Methods: A cross-sectional survey was conducted among 2 000 FSWs, 200 men who have sex with men (MSM), 200 drug users, 1 200 male migrants, 5 600 young students, as well as hospital patients and pregnant women in Lhasa, Qamdo, Nyingchi, Xigaze Shannan, Ali and Nagqum from June to December 2015. Face to face interviews were conducted to collect their demographic and behavioral information, and blood samples were collected for the tests of HIV, syphilis and hepatitis C virus (HCV) antibodies. The enumeration data were described by using rate and constituent. Results: A total of 20 597 participants were involved in cross-sectional survey. The positive rates of HIV and syphilis antibodies were 5.81%(124/2 133) and 0.05% (1/2 133) respectively among FSWs. The positive rates of HIV and syphilis antibodies were the same (9.80%,10/102) among MSM. There were no HIV infection detected in among drug users, male migrants and young students, but the positive rates of syphilis antibody were 4.00%(4/100), 0.33%(4/1 297) and 0.08%(4/5 095) respectively. The positive rates of HIV and syphilis antibodies were 0.04%(2/5 565) and 1.64%(91/5 565) among hospital patients. The positive rates of HIV and syphilis antibodies were 0.11%(7/6 305) and 1.19%(75/6 305)among pregnant women. The positive rates of HCV antibody were 1.00% (1/100) among drug users and less than 0.50% in other risk populations. The overall consistent condom use rate was low. Conclusions: In Tibet, HIV infection mainly occurred in the MSM, syphilis mainly occurred in FSWs and MSM, HCV infection mainly occurred in drug users. The AIDS related knowledge awareness rate was low in these risk populations, and less of them received intervention service.

Abstract
The electronic structure of BiFeO3 has been investigated by using electron energy loss spectrum and first-principle calculations. Assignments of the individual interband transitions have been accomplished by comparing the interband transition energy with the calculated PDOS. The DOS is mainly divided into two regions, the hybridized region of O 2p with Fe 3p in the valence band and that of O 2p hybridized with Bi 6p in the conduction band. From the simulation of high energy-loss near-edge structure, the core-hole effect is believed to be more significant. The feature groups for the experimental spectra of O K-edge and Fe L2,3-edge are consistent with simulation results.

Abstract
Because of its ideal band gap, high density and high electron mobility-lifetime product, cadmium zinc telluride (CdZnTe or CZT) is currently the best room-temperature compound-semiconductor X- and gamma-ray detector material. However, because of its innate poor thermo-physical properties and above unity segregation coefficient for Zn, the wide spread deployment of this material in large-volume CZT detectors is still limited by the high production cost. The underlying reason for the low yield of high-quality material is that CZT suffers from three major detrimental defects: compositional inhomogeneity, high concentrations of dislocation walls/sub-grain boundary networks and high concentrations of Te inclusions/precipitates. To mitigate all these disadvantages, we report for the first time the effects of the addition of selenium to the CZT matrix. The addition of Se was found to be very effective in arresting the formation of sub-grain boundaries and its networks, significantly reducing Zn segregation, improving compositional homogeneity and resulting in much lower concentrations of Te inclusions/precipitates. Growth of the new quaternary crystal Cd1−xZnxTe1−ySey (CZTS) by the Traveling Heater Method (THM) is reported in this paper. We have demonstrated the production of much higher yield according to its compositional homogeneity, with substantially lower sub-grain boundaries and their network, and a lower concentration of Te inclusions/precipitates.

Abstract
The development of the photostable higher-order multiphoton-excited (MPE) upconversion single microcrystalline material is fundamentally and technologically important, but very challenging. Here, up to five-photon excited luminescence in a host-guest metal-organic framework (MOF) and perovskite quantum dot (QD) hybrid single crystal ZJU-28⊃MAPbBr3 is shown via an in situ growth approach. Such a MOF strategy not only results in a high QD loading concentration, but also significantly diminishes the aggregation-caused quenching (ACQ) effect, provides effective surface passivation, and greatly reduces the contact of the QDs with the external bad atmosphere due to the confinement effect and protection of the framework. These advantages make the resulting ZJU-28⊃MAPbBr3 single crystals possess high PLQY of ≈51.1%, a high multiphoton action cross-sections that can rival the current highest record (measured in toluene solution), and excellent photostability. These findings liberate the excellent luminescence and nonlinear optical properties of perovskite QDs from the solution system to the solid single-crystal system, which provide a new avenue for the exploitation of high-performance multiphoton excited hybrid single microcrystal for future optoelectronic and micro-nano photonic integration applications.

Abstract
A diaphragm-free fiber gas pressure sensor based on the extrinsic Fabry-Perot interferometer (EFPI) is proposed and experimentally demonstrated. The sensor is fabricated by fusion splicing a sandwich structure of a single mode fiber, a hollow core fiber (HCF), and a coreless fiber. A femtosecond (fs) laser is employed to drill a micro-channel on the side wall of the HCF to allow gas entering/exiting the HCF. The refractive index of the gas has a linear relationship with the gas pressure. Thus, the gas pressure can be detected by investigating the optical path difference of the EFPI. The experimental results show that the proposed sensor exhibits a high gas pressure sensitivity of ∼1.80 µm/MPa from vacuum to 10 MPa at room temperature. Pressure responses under high temperatures are also investigated. The proposed sensor has properties of robust structure, miniature size, large measuring range, and high sensitivity.

Abstract
AIMS The underlying mechanisms of vitamin D receptor (VDR) and osteoprotegerin (OPG) genetic variation associated with bone mineral density and osteoporosis remain uncertain. This study aimed to investigate the association of VDR and OPG gene polymorphism as well as gene-gene interaction and their haplotype combination with the risk of osteoporosis. METHODS Polymerase chain reaction restriction fragment length polymorphism was carried out for single nucleotide polymorphism (SNP) detection. Generalized multifactor dimension reduction (GMDR) is used to identify the interaction. SHEsis software evaluated the haplotype and logistic regression was performed to assess the association between the SNPs within the VDR and OPG genes and osteoporosis. RESULTS The risk of osteoporosis in the VDR-rs2228570 polymorphism T-allele carriers was significantly higher than that in CC (CT/TT versus CC) individuals (adjusted odds ratio [OR] [95% confidence interval (CI)] = 1.76 [1.33-2.22]). The risk of osteoporosis was also higher in the G-allele carrier of the OPG-rs3102735 polymorphism than in individuals with the AA genotype (AG/GG vs. AA) (adjusted OR [95% CI] = 1.65 [1.27-2.14]). However, after adjusting for sex, age, and waist circumference covariates, no significant association of VDR-rs17879735 and OPG-rs2073618 with the osteoporosis risk was revealed. The GMDR method identified that gene-gene interactions were significant, but not for gene/AO interaction. Haplotypes were analyzed with SHEsis software. We did not detect a high-risk haplotype combination associated with osteoporosis. CONCLUSIONS Both VDR-rs2228570-T and OPG-rs3102735-G and their interactions are related to the increased risk of osteoporosis.

Abstract
A biocompatible metal-organic framework Zn-GA comprising zinc ions and the bio-friendly molecule l-glutamic acid (GA) is synthesized as a drug delivery system, and controlled drug release triggered by pH and thermal stimuli without premature delivery is realized. The anticancer drug methotrexate (MTX) is selected to be encapsulated into the crystal which possesses one-dimensional channels along the a axis. The on-command drug carrier shows superior biocompatibility, extremely low toxicity, satisfactory loading capabilities and excellent dual-responsiveness, indicating its practical application as an efficient drug carrier with controlled release.

Abstract
Objective: To understand the characteristics of new-type drug consumption, sexual behaviors and the prevalence of HIV infection among male new-type drug users in Qingdao, Shandong province. Methods: A cross sectional survey was conducted from 2015 to 2016. Participants were recruited from MSM community-based organizations (CBO) and general community through snowball method, relying on volunteers and male peer educators who were on new-type drugs themselves. Face-to-face interview was carried to collect information on drug use and sexual behaviors. Blood samples were collected to test HIV, syphilis and HCV antibodies. Urine samples were collected to test the evidence of new-type drugs. Qualitative variables and quantitative variables were analyzed using Chi-square test/Fisher's exact test and Student's t-test respectively. Multivariate logistic regression was used to analyze related factors of binary variables. Results: A total of 1 034 newtype drug users were recruited, including 431 (41.7%) MSM population and 603 (58.3%) who were not MSM. Compared with the the group of people who were not MSM, people in the the MSM group were younger, unmarried and with higher level of education. The proportion of methamphetamine users were 49.7% (214/431) and 100.0% (603/603) among the groups of MSM or not MSM, respectively. People in the MSM group, 66.8% (288/431) used 5-Methoxy-N, N-diisopropyltryptamine (5-MeODIPT, "foxy" ) in the last six months. However, none from the not-MSM group ever used 5-MeO-DIPT. In the last six months, proportions of sharing new-type drugs with more than two people in the MSM or not groups were 87.9% (379/431) and 97.7% (588/602), respectively (χ(2)=39.84, P<0.01). Proportions of unprotected sexual behavior among the MSM or not groups were 47.5% (285/600) and 7.4% (32/430) respectively (χ(2)=190.10, P<0.01). The proportions of 'group sex' after using drugs among the two groups were 78.1% (335/429) and 5.5% (33/600) respectively (χ(2)=573.73, P<0.01). The prevalence rates of HIV, syphilis and HCV antibody positive among the MSM or not groups were 2.1% and 0.2%, 3.3% and 6.3%, 0.0% and 0.3%, respectively. Conclusion: The prevalence of sharing new-type drugs with more than two people was high among male new-type drug users in Qingdao city. Male new-type-drug-users who were MSM, presented both high prevalence of group sex and HIV infection, and with less condom use. Intervention measures towards this sub-population should be strengthened.
