Isospin Amplitudes in Λ_{b}^{0}→J/ψΛ(Σ^{0}) and Ξ_{b}^{0}→J/ψΞ^{0}(Λ) Decays. PHYSICAL REVIEW LETTERS 2020; 124:111802. [PMID: 32242683 DOI: 10.1103/physrevlett.124.111802] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Revised: 01/08/2020] [Accepted: 02/14/2020] [Indexed: 06/11/2023]
Abstract
Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions and allow searches for physics beyond the standard model. We present the first results on isospin amplitudes in b-baryon decays, using data corresponding to an integrated luminosity of 8.5 fb^{-1}, collected with the LHCb detector in pp collisions at center of mass energies of 7, 8, and 13 TeV. The isospin amplitude ratio |A_{1}(Λ_{b}^{0}→J/ψΣ^{0})/A_{0}(Λ_{b}^{0}→J/ψΛ)|, where the subscript on A indicates the final-state isospin, is measured to be less than 1/21.8 at 95% confidence level. The Cabibbo suppressed Ξ_{b}^{0}→J/ψΛ decay is observed for the first time, allowing for the measurement |A_{0}(Ξ_{b}^{0}→J/ψΛ)/A_{1/2}(Ξ_{b}^{0}→J/ψΞ^{0})|=0.37±0.06±0.02, where the uncertainties are statistical and systematic, respectively.

First Observation of Excited Ω_{b}^{-} States. PHYSICAL REVIEW LETTERS 2020; 124:082002.

Abstract
We report four narrow peaks in the Ξ_{b}^{0}K^{-} mass spectrum obtained using pp collisions at center-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb^{-1} recorded by the LHCb experiment. Referring to these states by their mass, the mass values are m[Ω_{b}(6316)^{-}]=6315.64±0.31±0.07±0.50 MeV, m[Ω_{b}(6330)^{-}]=6330.30±0.28±0.07±0.50 MeV, m[Ω_{b}(6340)^{-}]=6339.71±0.26±0.05±0.50 MeV, m[Ω_{b}(6350)^{-}]=6349.88±0.35±0.05±0.50 MeV, where the uncertainties are statistical, systematic, and the last is due to the knowledge of the Ξ_{b}^{0} mass. The natural widths of the three lower mass states are consistent with zero, and the 90% confidence-level upper limits are determined to be Γ[Ω_{b}(6316)^{-}]<2.8 MeV, Γ[Ω_{b}(6330)^{-}]<3.1 MeV and Γ[Ω_{b}(6340)^{-}]<1.5 MeV. The natural width of the Ω_{b}(6350)^{-} peak is 1.4_{-0.8}^{+1.0}±0.1 MeV, which is 2.5σ from zero and corresponds to an upper limit of 2.8 MeV. The peaks have local significances ranging from 3.6σ to 7.2σ. After accounting for the look-elsewhere effect, the significances of the Ω_{b}(6316)^{-} and Ω_{b}(6330)^{-} peaks are reduced to 2.1σ and 2.6σ, respectively, while the two higher mass peaks exceed 5σ. The observed peaks are consistent with expectations for excited Ω_{b}^{-} resonances.

Abstract
Searches are performed for both promptlike and long-lived dark photons, A^{'}, produced in proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for A^{'}→μ^{+}μ^{-} decays using a data sample corresponding to an integrated luminosity of 5.5 fb^{-1} collected with the LHCb detector. Neither search finds evidence for a signal, and 90% confidence-level exclusion limits are placed on the γ-A^{'} kinetic mixing strength. The promptlike A^{'} search explores the mass region from near the dimuon threshold up to 70 GeV and places the most stringent constraints to date on dark photons with 214<m(A^{'})≲740 MeV and 10.6<m(A^{'})≲30 GeV. The search for long-lived A^{'}→μ^{+}μ^{-} decays places world-leading constraints on low-mass dark photons with lifetimes O(1) ps.

Abstract
Observations are reported of different sources of CP violation from an amplitude analysis of B^{+}→π^{+}π^{+}π^{-} decays, based on a data sample corresponding to an integrated luminosity of 3 fb^{-1} of pp collisions recorded with the LHCb detector. A large CP asymmetry is observed in the decay amplitude involving the tensor f_{2}(1270) resonance, and in addition significant CP violation is found in the π^{+}π^{-}S wave at low invariant mass. The presence of CP violation related to interference between the π^{+}π^{-}S wave and the P wave B^{+}→ρ(770)^{0}π^{+} amplitude is also established; this causes large local asymmetries but cancels when integrated over the phase space of the decay. The results provide both qualitative and quantitative new insights into CP -violation effects in hadronic B decays.

Abstract
OBJECTIVES To assess the association between malnutrition and physical frailty among nursing home older adults in China. DESIGN AND SETTING A cross-sectional study in 15 nursing homes in Changsha, China. PARTICIPANTS A total of 705 nursing home residents who were aged 60 and older. MEASUREMENTS Physical frailty was identified based on the following five components: slow gait speed, low physical activity, weight loss, exhaustion, and low grip strength. Nutritional status was assessed using the Mini Nutritional Assessment. Multinomial logistic regression models were used to analyze the association between nutritional status and physical frailty. RESULTS The mean (SD) age of the participants was 82.5 (8.1) years old (range, 60-106 years), and 226 (32%) was men. Of those participants, 5.1% and 55.6% were malnourished and at risk of malnutrition, respectively; 60.3% and 36.2% were identified as being frail and prefrail, respectively. Compared with participants who were well-nourished, those who were at risk of malnutrition or malnourished were two times more likely to be physically frail (adjusted odds ratio 2.66, 95% confidence interval 1.01 to 7.00), after adjustment for age, education level, cognitive status, depressive symptoms, and disability in activities of daily living. No significant association was observed between malnutrition and physical prefrailty. CONCLUSION Our findings suggest that poor nutritional status and physical frailty are highly prevalent in nursing home older adults in China, and that poor nutritional status is associated with increased odds of physical frailty.

Abstract
A search for the lepton-flavor violating decays B^{+}→K^{+}μ^{±}e^{∓} is performed using a sample of proton-proton collision data, collected with the LHCb experiment at center-of-mass energies of 7 and 8 TeV and corresponding to an integrated luminosity of 3 fb^{-1}. No significant signal is observed, and upper limits on the branching fractions are set as B(B^{+}→K^{+}μ^{-}e^{+})<7.0(9.5)×10^{-9} and B(B^{+}→K^{+}μ^{+}e^{-})<6.4(8.8)×10^{-9} at 90% (95)% confidence level. The results improve the current best limits on these decays by more than one order of magnitude.

Measurement of Charged Hadron Production in Z-Tagged Jets in Proton-Proton Collisions at sqrt[s]=8 TeV. PHYSICAL REVIEW LETTERS 2019; 123:232001. [PMID: 31868452 DOI: 10.1103/physrevlett.123.232001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2019] [Revised: 06/13/2019] [Indexed: 06/10/2023]
Abstract
The production of charged hadrons within jets recoiling against a Z boson is measured in proton-proton collision data at sqrt[s]=8 TeV recorded by the LHCb experiment. The charged-hadron structure of the jet is studied longitudinally and transverse to the jet axis for jets with transverse momentum p_{T}>20 GeV and in the pseudorapidity range 2.5<η<4. These are the first measurements of jet hadronization at these forward rapidities and also the first where the jet is produced in association with a Z boson. In contrast to previous hadronization measurements at the Large Hadron Collider, which are dominated by gluon jets, these measurements probe predominantly light-quark jets which are found to be more longitudinally and transversely collimated with respect to the jet axis when compared to the previous gluon dominated measurements. Therefore, these results provide valuable information on differences between quarks and gluons regarding nonperturbative hadronization dynamics.

Abstract
The first amplitude analysis of the B^{±}→π^{±}K^{+}K^{-} decay is reported based on a data sample corresponding to an integrated luminosity of 3.0 fb^{-1} of pp collisions recorded in 2011 and 2012 with the LHCb detector. The data are found to be best described by a coherent sum of five resonant structures plus a nonresonant component and a contribution from ππ↔KK S-wave rescattering. The dominant contributions in the π^{±} K^{∓} and K^{+} K^{-} systems are the nonresonant and the B^{±}→ρ(1450)^{0}π^{±} amplitudes, respectively, with fit fractions around 30%. For the rescattering contribution, a sizable fit fraction is observed. This component has the largest CP asymmetry reported to date for a single amplitude of (-66±4±2)%, where the first uncertainty is statistical and the second systematic. No significant CP violation is observed in the other contributions.

Abstract
Results are reported from a search for the rare decays B_{s}^{0}→τ^{±}μ^{∓} and B^{0}→τ^{±}μ^{∓}, where the τ lepton is reconstructed in the channel τ^{-}→π^{-}π^{+}π^{-}ν_{τ}. These processes are effectively forbidden in the standard model, but they can potentially occur at detectable rates in models of new physics that can induce lepton-flavor-violating decays. The search is based on a data sample corresponding to 3 fb^{-1} of proton-proton collisions recorded by the LHCb experiment in 2011 and 2012. The event yields observed in the signal regions for both processes are consistent with the expected standard model backgrounds. Because of the limited mass resolution arising from the undetected τ neutrino, the B_{s}^{0} and B^{0} signal regions are highly overlapping. Assuming no contribution from B^{0}→τ^{±}μ^{∓}, the upper limit B(B_{s}^{0}→τ^{±}μ^{∓})<4.2×10^{-5} is obtained at 95% confidence level. If no contribution from B_{s}^{0}→τ^{±}μ^{∓} is assumed, a limit of B(B^{0}→τ^{±}μ^{∓})<1.4×10^{-5} is obtained at 95% confidence level. These results represent the first limit on B(B_{s}^{0}→τ^{±}μ^{∓}) and the most stringent limit on B(B^{0}→τ^{±}μ^{∓}).

Abstract
OBJECTIVE To investigate the prevalence and vertical transmission rate of Toxoplasma gondii infections among in parturient women in Wuhu City, so as to provide reference for the prevention and control of toxoplasmosis among pregnant women in the city. METHODS Parturient women's venous blood samples and neonatal heel blood samples were collected in Wuhu City and prepared into filter-paper blood samples. The prevalence and vertical transmission rate of T. gondii infections were detected using the loop -mediated isothermal amplification (LAMP) assay among the parturient women. RESULTS There were three positive samples detected in the 475 filter-paper blood samples from the parturient women, with a mean positive rate of 0.63%. The prevalence of T. gondii infection was 0 in pregnant women at ages of < 20 years (0/5) and at an advanced maternal age (0/24), while the prevalence was 0.67% (3/446) in pregnant women at an appropriate maternal age. T. gondii infection was detected in 2 filter-paper blood samples from newborns, with a vertical transmission rate of 66.67%. CONCLUSIONS There is T. gondii infection in the parturient women and a high vertical transmission rate of T. gondii infection is detected in Wuhu City. The awareness of the potential risk factors of toxoplasmosis should be improved among pregnant women to prevent the damages of toxoplasmosis to humans.

Abstract
OBJECTIVE Rheumatoid Arthritis (RA) is a chronic systemic autoimmune disease, whereas its cause still remains elusive. Typical pathological manifestations of RA include persistent synovitis and bone degeneration in the surrounding joints. Although the incidence of RA is high in population, currently there have been no effective cures for it. The purpose of this study is to investigate the therapeutic effects and main mechanism of IKKε (inhibitor of nuclear factor kappa-B kinase ε) in collagen II induced- Rheumatoid Arthritis (CIA) mice model. MATERIALS AND METHODS IKKε-/- and wild-type (WT) littermate control mice were intraperitoneally injected with 5 mg/kg collagen II monoclonal antibody cocktail (Cab) for 5 days. After that, the nociception threshold and clinical rheumatoid arthritis articular damage score of mice were evaluated. After 5 days-CAb treatment, serum levels of a series of inflammatory cytokines including interleukin-6 (IL-6), IL-1β, tumor necrosis factor-α (TNF-α) and interferon (IFN) were detected with enzyme-linked immunosorbent assay (ELISA) in both groups. Besides, Real-time reverse transcription polymerase chain reaction (Real-time RT-PCR) was used to evaluate the expression of these inflammatory cytokines in plantar tissues. In addition, Western blot was performed to investigate the protein levels of NF-κB (nuclear factor kappa-light-chain-enhancer of activated B) signaling pathway. Moreover, WT mice receiving CAb were further applied with or without IKK inhibitor amlexanox (25 mg/kg) to investigate the expression of the above-mentioned inflammatory cytokines. RESULTS Our work showed that IKKε-/- mice with CIA displayed less nociception and suppressed inflammatory response than WT mice. Meanwhile, the clinical rheumatoid arthritis articular damage scores were significantly decreased in IKKε-/- mice. The levels of TNF-α, IL-1β, IL-6 in serum and plantar tissues in IKKε-/- mice were significantly lower than those in WT mice. Besides, NF-κB expression in IKKε-/- mice was significantly decreased. Similarly, the same phenotype was observed in WT mice administrated with IKKε inhibitor amlexanox as that of IKKε-/- mice, indicating that inflammatory and nociception responses were remarkably decreased than those of the negative controls. CONCLUSIONS IKKε plays an important role in promoting nociception and inflammatory response in CIA. Our research demonstrated that knockout of IKKε may serve as a new direction for clinical prevention and treatment of rheumatoid arthritis. IKKε inhibitor amlexanox may become a new drug for the treatment of rheumatoid arthritis.

Abstract
Objective:Imaging findings and treatment of sharp foreign bodies penetrating the esophagus to migrate in the neck were collected. Method:All of 9 cases were determined by CT imaging. The foreign bodies were removed in 8 cases through the lateral cervical approach. The last case was taken out by bronchoscope. Eight cases successfully removed the foreign bodies. No definite foreign body was found in 1 case. Result:There were no postoperative complications in 8 patients that successful removed of foreign bodies. All patients begin to eat normally after operation and were discharged from hospital in 7 days. Tracheoesophageal fistula occurred that happened to the patient that no foreign body was found in operation. So gastric tube was retained for 7 days. Conclusion:CT imaging should be performed to determine whether there is the possibility of foreign body penetrating out of the esophagus, for the patients who had explicit history but the foreignbodies could not be found by barium meal examination. If necessary, three-dimensional CT reconstruction of the neck should be performed to locate the foreign body. Surgical exploration should be done as soon as possible to avoid aimless migration of foreign bodies, and it is difficult to find it during operation.

Effects of three different first-aid training methods on knowledge retention of caregivers and teachers: a randomized and longitudinal cohort study in China. Public Health 2019; 178:97-104. [PMID: 31648067 DOI: 10.1016/j.puhe.2019.08.021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 07/27/2019] [Accepted: 08/23/2019] [Indexed: 12/09/2022]
Abstract
OBJECTIVES The purpose of this study was to assess the effects of pediatric first-aid training methods on caregivers' and teachers' knowledge retention. STUDY DESIGN This was a randomized longitudinal cohort study. METHODS A stratified random sampling method was used to select 1282 caregivers and teachers with the help of local education authorities in 18 districts and 1 county of Shanghai, China. The selected caregivers and teachers were randomly allocated into groups that were exposed to 3 models of training, including an interactive training model (group A), lecture-based training model (group B), and video instruction training model (group C), for pediatric first-aid training for caregivers and teachers (PedFACTs). Before and after the training, a descriptive questionnaire composed of demographic information and 37 simple-choice questions about first aid was administered. During the follow-up, 120 caregivers and teachers from each of the three methods were randomized and retested 9 months after their training and 120 caregivers and teachers were randomly reselected in each of the three methods and retested 4 years after their training. RESULTS Immediately after training, there was a significant difference in the postassessment results between groups A and B (P = 0.002) as well as between groups A and C (P < 0.001). The average interactive training model score was the highest, followed by the instruction training model and video instruction training model. There was no significant difference among the three groups in the reassessment scores at 9 months and 4 years after training (P = 0.744, P = 0.595). The difference in passing the assessment among the three groups at 9 months or 4 years after training was not maintained at a significant level. CONCLUSION The three training methods did not affect knowledge retention of the caregivers and teachers at nine months or four years after training completion. Video instruction may be an effective, convenient, and feasible method to train caregivers and teachers.

Abstract
We report the observation of a new structure in the Λ_{b}^{0}π^{+}π^{-} spectrum using the full LHCb data set of pp collisions, corresponding to an integrated luminosity of 9 fb^{-1}, collected at sqrt[s]=7, 8, and 13 TeV. A study of the structure suggests its interpretation as a superposition of two almost degenerate narrow states. The masses and widths of these states are measured to be m_{Λ_{b}(6146)^{0}}=6146.17±0.33±0.22±0.16 MeV,m_{Λ_{b}(6152)^{0}}=6152.51±0.26±0.22±0.16 MeV,Γ_{Λ_{b}(6146)^{0}}=2.9±1.3±0.3 MeV,Γ_{Λ_{b}(6152)^{0}}=2.1±0.8±0.3 MeV,with a mass splitting of Δm=6.34±0.32±0.02 MeV, where the first uncertainty is statistical, the second systematic. The third uncertainty for the mass measurements derives from the knowledge of the mass of the Λ_{b}^{0} baryon. The measured masses and widths of these new excited states suggest their possible interpretation as a doublet of Λ_{b}(1D)^{0} states.

Abstract
OBJECTIVE To investigate the role of microRNA-155 (miR-155) in the potential invasion of colon cancer cell and the underlying mechanism. PATIENTS AND METHODS The expression level of miR-155 in colon cancer and adjacent normal tissues was detected by Real-time quantitative polymerase chain reaction (RT-PCR). miR-155 mimics (miR-155), or siRNA against β-catenin (β-catenin siRNA), was transfected into human colon cancer cell line SW-480 using Lipofectamine 2000, respectively. RT-PCR was used to measure the expression levels of miR-155 and β-catenin mRNA, and β-catenin protein expression level was detected by Western blot. The in-vitro cell invasion abilities were determined by transwell invasion assays after up-regulating miR-155 or knocking down of β-catenin. RESULTS MiR-155 directly regulates β-catenin at the transcriptional level, and promotes the invasion potential of colon cancer cell, at least partly through the upregulation of β-catenin. CONCLUSIONS The findings of this study suggest that miR-155 and β-catenin may have a unique potential as a novel biomarker candidate for diagnosis and treatment of tumor metastasis.

Abstract
OBJECTIVE Epidural fibrosis, one of the common complications after spinal surgery, seriously affects the surgical decompression effect. Effectively inhibiting the fibrous tissue hyperplasia is pivotal to reduce the scar adhesion. Previous studies showed that early growth response 1 (EGR1) is associated with the fibroblast reactivity induced by transforming growth factor-beta (TGF-β) and plays a vital regulatory role in scar formation; however, the upstream targets and mechanisms still remain unclear. In this work, it was found that the level of long non-coding ribonucleic acid (lncRNA)-cyclooxygenase-2 (COX2) was significantly negatively correlated with EGR1 expression and the severity of the scar. Therefore, it was conjectured that lncRNA-COX2 may decrease fibroplasia and scar formation by negatively regulating EGR1. MATERIALS AND METHODS TGF-β was used to activate the embryonic and adult rat fibroblasts. Rats underwent laminectomy to establish the epidural fibrosis model. The changes in the levels of fibroplasia-related genes were measured and analyzed through messenger RNA (mRNA), lncRNA, and micro RNA expression profile chips. Quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) was applied to determine the levels of EGR1 and lncRNA-COX2, and Western blotting was adopted to detect the content of EGR1, collagen I (Col-1), Col-3, and alpha-smooth muscle actin (α-SMA). The scar formation was reflected by hematoxylin and eosin (HE) staining and Masson staining, and the expression level of α-SMA in the scar tissues was measured via immunohistochemistry. Finally, micro-magnetic resonance imaging (MRI) was utilized to examine the different degrees of epidural fibroplasia. RESULTS It was found that the reactivity of embryonic rat fibroblasts to the TGF-β stimulation was different from that of adult rat fibroblasts. LncRNA-COX2 was highly expressed in the embryonic rat fibroblasts, but lowly expressed in the adult rat fibroblasts, which had negative correlations with the EGR1 level in embryonic and adult rat fibroblasts. In addition, it was revealed that the expression of EGR1 in the adult rat fibroblasts was remarkably higher than that in the embryonic rat fibroblasts after the activation with TGF-β. Meanwhile, the level of lncRNA-COX2 was lowered after the activation, especially in the adult rat fibroblasts. It was discovered in the in-vivo model that the degree of fibroplasia was positively associated with EGR1 level and negatively correlated with lncRNA-COX2 level. CONCLUSIONS The results of this research elucidated that the down-regulation of lncRNA-COX2 is involved in the epidural scar formation and related to the elevated EGR1 level which regulates the activation of fibroblasts and secretion of massive extracellular matrixes, suggesting that lncRNA-COX2 may modulate the role of fibroblasts in scar formation as an upstream action target of EGR1.

Measurement of CP-Violating and Mixing-Induced Observables in B_{s}^{0}→ϕγ Decays. PHYSICAL REVIEW LETTERS 2019; 123:081802.

Abstract
A time-dependent analysis of the B_{s}^{0}→ϕγ decay rate is performed to determine the CP -violating observables S_{ϕγ} and C_{ϕγ} and the mixing-induced observable A_{ϕγ}^{Δ}. The measurement is based on a sample of pp collision data recorded with the LHCb detector, corresponding to an integrated luminosity of 3 fb^{-1} at center-of-mass energies of 7 and 8 TeV. The measured values are S_{ϕγ}=0.43±0.30±0.11, C_{ϕγ}=0.11±0.29±0.11, and A_{ϕγ}^{Δ}=-0.67_{-0.41}^{+0.37}±0.17, where the first uncertainty is statistical and the second systematic. This is the first measurement of the observables S and C in radiative B_{s}^{0} decays. The results are consistent with the standard model predictions.

Abstract
Structural rejuvenation of glasses not only provides fundamental insights into their complicated dynamics but also extends their practical applications. However, it is formidably challenging to rejuvenate a glass on very short time scales. Here, we present the first experimental evidence that a specially designed shock compression technique can rapidly rejuvenate metallic glasses to extremely high-enthalpy states within a very short time scale of about 365 ± 8 ns. By controlling the shock stress amplitude, the shock-induced rejuvenation is successfully frozen at different degrees. The underlying structural disordering is quantitatively characterized by the anomalous boson heat capacity peak of glasses. A Deborah number, defined as a competition of time scales between the net structural disordering and the applied loading, is introduced to explain the observed ultrafast rejuvenation phenomena of metallic glasses.

Abstract
Objective: To analyze the clinicopathological features and prognosis of patients in endometrial cancer with bone metastases. Methods: A retrospective review of medical records was performed to analyze patients with endometrial cancer who developed bone metastases at Peking Union Medical College Hospital (PUMCH) from January 2004 to December 2017, including patients with bone metastases at the diagnosis of endometrial cancer and at recurrence of endometrial cancer. The patient's clinicopathological features, bone metastasis characteristics, treatment process and prognoses were also analyzed. Results: The incidence of bone metastasis of endometrial cancer in PUMCH from 2004 to 2017 was 0.57% (14/2 458). (1) General clinical pathological features: the median age of the 7 patients with bone metastases diagnosed at the time of initial diagnosis was 50 years old, and the main pathological type was endometrioid carcinoma (n=5). The median age of the other 7 patients was 57 years old, with no significant difference comparing to the former groups (P=0.559). (2) The majority site of bone metastasis in endometrial cancer were discovered in pelvic bones, followed by the tibia. (3) Treatment: according to the staging of endometrial cancer, a comprehensive treatment based on surgery was performed, and one patient with isolated bone metastases underwent resection of bone metastasis. (4) Prognosis: nine out of the 14 patients died during the follow-up period. The median over all survival time was 25.5 months (range: 7.7-258.0 months). The median survival of population after diagnosis of bone metastases was 15.0 months (range: 3.0-51.0 months). The survival rate of endometrial cancer at 1-year after diagnosis of bone metastasis was 71.4%. The 2-year survival rate was 40.8%. (5) No independent prognostic factors affecting survival was found (P>0.05). Conclusions: The incidence of bone metastasis in endometrial cancer is less than 1%. Bone metastasis could occur at the diagnosis of endometrial cancer or recurrence of endometrial cancer. Bone metastasis suggests a poor prognosis. There is no standard follow-up and treatment protocols so that individualized treatment is needed.

Abstract
The radiative decay Λ_{b}^{0}→Λγ is observed for the first time using a data sample of proton-proton collisions corresponding to an integrated luminosity of 1.7 fb^{-1} collected by the LHCb experiment at a center-of-mass energy of 13 TeV. Its branching fraction is measured exploiting the B^{0}→K^{*0}γ decay as a normalization mode and is found to be B(Λ_{b}^{0}→Λγ)=(7.1±1.5±0.6±0.7)×10^{-6}, where the quoted uncertainties are statistical, systematic, and systematic from external inputs, respectively. This is the first observation of a radiative decay of a beauty baryon.

Abstract
Gastric cancer (GC) is a malignant tumor that affects individuals worldwide, and miRNA and mRNA are closely connected to this disease. However, it is still unclear how these molecules affect GC and whether their effects are associated with circRNA in GC patients. Therefore, we obtained the miRNA, mRNA and circRNA expression profiles of GC patients from the GEO database. For comparison, shared miRNAs and mRNAs from the results of microarrays were annotated by gene ontology (GO) and pathway analysis. We also identified mRNAs that were targeted by miRNA through TargetScan 7.2 and circRNAs that were targeted by miRNA through CircInteractome. A comprehensive analysis of the microarray results revealed 72 shared miRNAs, and the expression profiles of 6 miRNAs were significantly different between the tumor and control groups (the absolute value of fold change>2, P<0.05). Hsa-miR-1, hsa-miR-142-3p, hsa-miR-95, hsa-miR-133a and hsa-miR-181d were upregulated in GC, whereas hsa-miR-375 was downregulated. The analysis results also revealed 1201 shared mRNAs and 27 mRNAs, respectively, by microarray and TargetScan. Pathway analysis demonstrated that the Glypican pathway, Proteoglycan syndecan-mediated signalling events, Glypican 1 network and PAR1-mediated thrombin signalling events play important roles. GO analysis revealed significant enrichment in the three terms cellular component, molecular function and biological process, suggesting that organelles, enzyme binding, RNA-binding and nitrogen metabolism may have a strong relationship in GC. The increase in PAX6 in GC may be related to hsa-miR-375. Three circRNAs, hsa_circ_0001658, hsa_circ_0004928 and hsa_circ_0000376, were then found to be significantly differentially expressed between GC and normal tissues (the absolute value of fold change>2, P<0.05). In conclusion, the circ0001658/circ0004928/circ0000376-miR-375-PAX6 axis may represent a new regulatory network that should be further investigated, and the results of this study provide a better understanding of GC.
