[A monogenic lupus family caused by homozygous deletions of DNASE1L3 gene and literature review]

Objective: To report the clinical features and genetic variations of monogenic lupus caused by DNASE1L3 deficiency and to introduce preliminary experience on diagnosis and treatment for this disease. Methods: Clinical data of 3 children from the same pedigree were collected who were diagnosed with DNASE1L3 defect-associated monogenic lupus in August 2020 by Department of Pediatrics, Peking Union Medical College Hospital referred from Department of Pediatrics, Boai Hospital of Zhongshan. DNA was extracted from the peripheral blood of the patients and their parients to perform genetic analysis and confirmation. Six interferon-stimulated genes were relatively quantified to examine the activation of the type I interferon signaling. "DNASE1L3" "systemic lupus erythematosus" and "SLE" were searched in PubMed, Wangfang Data, CNKI databases for related reports from database established date to June 2022. Spectrum of genetic variations and clinical phenotypes were analyzed in combination with this pedigree. Results: Case 1, a 14-year-old girl with edema, hematuria, and heavy proteinuria, presented with membranous nephropathy. Case 2, the 12-year-old younger brother of case 1 with hematologic, cardiac, pulmonary, renal involvement, positive antinuclear antibody, positive anti-double-stranded DNA antibody and low complement C3, manifested with systemic lupus erythematosus. Case 3, the 8-year-old younger sister of case 1 with hematologic, cardiac, pulmonary and renal involvement, positive antinuclear antibody, positive anti-double-stranded DNA antibody, and low complement C3 and C4, manifested with systemic lupus erythematosus. Genetic testing revealed that all 3 patients carried homozygous deletions in exons 3 and 4 on DNASE1L3 gene. Interferon scores were elevated in case 1, 2 and their parents but normal in case 3. All 3 patients were diagnosed with monogenic lupus caused by DNASE1L3 defects. Literature searching identified 10 relevant publications in English and 0 publication in Chinese, involving 42 patients from 18 pedigrees (including the 3 cases from this pedigree). Nine variants were found: c.289_290delAC (p.T97Ifs*2), c.643delT (p.W215Gfs*2), c.320+4delAGTA, c.321-1G>A, Ex5 del, c.433G>A, c.581G>A (p.C194Y), c.537G>A (p.W179X), and Ex3-4 del. The hotspot variants were c.643delT (43% (36/84)) and c.289_290delAC (36% (30/84)). Kidney was affected in 31 cases (74%) of the 42 cases. Among the 25 patients, joints were affected in 16 cases (64%), fever were reported in 13 cases (52%) hematologic system was involved 13 cases (52%), rash was present in 10 cases (40%), intestinal tract was involved in 8 cases (32%), lungs were involved in 6 cases (24%), eyes were involved in 4 cases (16%), and the heart was involved in 4 cases (16%). The 2 cardiopulmonary affected patients from literature showed poor prognosis, with 1 died, and 1 right heart failure. Conclusions: The clinical manifestations of monogenic lupus caused by DNASE1L3 defect are highly heterogenous, primarily with renal, blood, joint, intestinal, and cardiopulmonary involvement. There is no correlation between the genotype and the phenotype. DNASE1L3 defects were predominantly mediated by null varations including nonsense, splicing, frameshift and exon deletions. The hotspot variants are c.643delT and c.289_290delAC. DNASE1L3 defects should be cautioned in early-onset lupus-like patients with renal, joint and hematologic involvement. Cardiopulmonary involved patients require close monitoring for poor prognosis. Copy number variations should be carefully analyzed after negative whole exome sequencing.

Study of the Semileptonic Decay Λ_{c}^{+}→Λe^{+}ν_{e}

The study of the Cabibbo-favored semileptonic decay Λ_{c}^{+}→Λe^{+}ν_{e} is reported using a 4.5  fb^{-1} data sample of e^{+}e^{-} annihilations collected at center-of-mass energies ranging from 4.600 GeV to 4.699 GeV with the BESIII detector at the BEPCII collider. The branching fraction of the decay is measured to be B(Λ_{c}^{+}→Λe^{+}ν_{e})=(3.56±0.11_{stat}±0.07_{syst})%, which is the most precise measurement to date. Furthermore, we perform an investigation of the internal dynamics in Λ_{c}^{+}→Λe^{+}ν_{e}. We provide the first direct comparisons of the differential decay rate and form factors with those predicted from lattice quantum chromodynamics (LQCD) calculations. Combining the measured branching fraction with a q^{2}-integrated rate predicted by LQCD, we determine |V_{cs}|=0.936±0.017_{B}±0.024_{LQCD}±0.007_{τ_{Λ_{c}}}.

Measurement of the Absolute Branching Fraction and Decay Asymmetry of Λ→nγ

The radiative hyperon decay Λ→nγ is studied using (10087±44)×10^{6}  J/ψ events collected with the BESIII detector operating at BEPCII. The absolute branching fraction of the decay Λ→nγ is determined to be (0.832±0.038_{stat}±0.054_{syst})×10^{-3}, which is a factor of 2.1 lower and 5.6 standard deviations different than the previous measurement. By analyzing the joint angular distribution of the decay products, the first determination of the decay asymmetry α_{γ} is reported with a value of -0.16±0.10_{stat}±0.05_{syst}.

Observation of an Isoscalar Resonance with Exotic J^{PC}=1^{-+} Quantum Numbers in J/ψ→γηη^{'}

Using a sample of (10.09±0.04)×10^{9}  J/ψ events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/ψ→γηη^{'} is performed. The first observation of an isoscalar state with exotic quantum numbers J^{PC}=1^{-+}, denoted as η_{1}(1855), is reported in the process J/ψ→γη_{1}(1855) with η_{1}(1855)→ηη^{'}. Its mass and width are measured to be (1855±9_{-1}^{+6})  MeV/c^{2} and (188±18_{-8}^{+3})  MeV, respectively, where the first uncertainties are statistical and the second are systematic, and its statistical significance is estimated to be larger than 19σ.

Observation of an a_{0}-like State with Mass of 1.817 GeV in the Study of D_{s}^{+}→K_{S}^{0}K^{+}π^{0} Decays

Using e^{+}e^{-} annihilation data corresponding to an integrated luminosity of 6.32  fb^{-1} collected at center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform the first amplitude analysis of the decay D_{s}^{+}→K_{S}^{0}K^{+}π^{0} and determine the relative branching fractions and phases for intermediate processes. We observe an a_{0}-like state with mass of 1.817 GeV in its decay to K_{S}^{0}K^{+} for the first time. In addition, we measure the ratio {B[D_{s}^{+}→K[over ¯]^{*}(892)^{0}K^{+}]/B[D_{s}^{+}→K[over ¯]^{0}K^{*}(892)^{+}]} to be 2.35_{-0.23stat}^{+0.42}±0.10_{syst}. Finally, we provide a precision measurement of the absolute branching fraction B(D_{s}^{+}→K_{S}^{0}K^{+}π^{0})=(1.46±0.06_{stat}±0.05_{syst})%.

Precise Measurements of Decay Parameters and CP Asymmetry with Entangled Λ-Λ[over ¯] Pairs

Based on 10 billion J/ψ events collected at the BESIII experiment, a search for CP violation in Λ decay is performed in the difference between CP-odd decay parameters α_{-} for Λ→pπ^{-} and α_{+} for Λ[over ¯]→p[over ¯]π^{+} by using the process e^{+}e^{-}→J/ψ→ΛΛ[over ¯]. With a five-dimensional fit to the full angular distributions of the daughter baryon, the most precise values for the decay parameters are determined to be α_{-}=0.7519±0.0036±0.0024 and α_{+}=-0.7559±0.0036±0.0030, respectively. The Λ and Λ[over ¯] averaged value of the decay parameter is extracted to be α_{avg}=0.7542±0.0010±0.0024 with unprecedented accuracy. The CP asymmetry A_{CP}=(α_{-}+α_{+})/(α_{-}-α_{+}) is determined to be -0.0025±0.0046±0.0012, which is one of the most precise measurements in the baryon sector. The reported results for the decay parameter will play an important role in the studies of the polarizations and CP violations for the strange, charmed and beauty baryons.

First Observation of the Direct Production of the χ_{c1} in e^{+}e^{-} Annihilation

We study the direct production of the J^{PC}=1^{++} charmonium state χ_{c1}(1P) in electron-positron annihilation by carrying out an energy scan around the mass of the χ_{c1}(1P). The data were collected with the BESIII detector at the BEPCII collider. An interference pattern between the signal process e^{+}e^{-}→χ_{c1}(1P)→γJ/ψ→γμ^{+}μ^{-} and the background processes e^{+}e^{-}→γ_{ISR}J/ψ→γ_{ISR}μ^{+}μ^{-} and e^{+}e^{-}→γ_{ISR}μ^{+}μ^{-} is observed by combining all the data samples. The χ_{c1}(1P) signal is observed with a significance of 5.1σ. This is the first observation of a C-even state directly produced in e^{+}e^{-} annihilation. The electronic width of the χ_{c1}(1P) resonance is determined to be Γ_{ee}=(0.12_{-0.08}^{+0.13})  eV, which is of the same order of magnitude as theoretical calculations.

Evidence for a Neutral Near-Threshold Structure in the K_{S}^{0} Recoil-Mass Spectra in e^{+}e^{-}→K_{S}^{0}D_{s}^{+}D^{*-} and e^{+}e^{-}→K_{S}^{0}D_{s}^{*+}D^{-}

We study the processes e^{+}e^{-}→K_{S}^{0}D_{s}^{+}D^{*-} and e^{+}e^{-}→K_{S}^{0}D_{s}^{*+}D^{-}, as well as their charge conjugated processes, at five center-of-mass energies between 4.628 and 4.699 GeV, using data samples corresponding to an integrated luminosity of 3.8  fb^{-1} collected by the BESIII detector at the BEPCII storage ring. Based on a partial reconstruction technique, we find evidence of a structure near the thresholds for D_{s}^{+}D^{*-} and D_{s}^{*+}D^{-} production in the K_{S}^{0} recoil-mass spectrum, which we refer to as the Z_{cs}(3985)^{0}. Fitting with a Breit-Wigner line shape, we find the mass of the structure to be (3992.2±1.7±1.6)  MeV/c^{2} and the width to be (7.7_{-3.8}^{+4.1}±4.3)  MeV, where the first uncertainties are statistical and the second are systematic. The significance of the Z_{cs}(3985)^{0} signal is found to be 4.6σ including both the statistical and systematic uncertainty. We report the Born cross section multiplied by the branching fraction at different energy points. The mass of the Z_{cs}(3985)^{0} is close to that of the Z_{cs}(3985)^{+}. Assuming SU(3) symmetry, the cross section of the neutral channel is consistent with that of the charged one. Hence, we conclude that the Z_{cs}(3985)^{0} is the isospin partner of the Z_{cs}(3985)^{+}.

[Epidemiological investigation on allergic diseases related to animal dander of cats, dogs and horses]

Objective: A multicenter Chinese mainland survey was conducted to investigate the sensitization distribution characteristics of cat, dog and horse dander in patients with allergic diseases, so as to provide clinicians with epidemiological data of common animal allergens and useful information for the prevention and treatment of allergies in cats, dogs and horses. Methods: The epidemiological investigation and design was adopted. This study is based on the national epidemiological survey of allergic diseases led by the first affiliated Hospital of Guangzhou Medical University. From January to December in 2021, a total of 2 122 patients diagnosed with allergic diseases were included in the outpatient department of respiratory department/pediatrics/allergy department of 14 units such as the First Affiliated Hospital of Guangzhou Medical University, and 222 healthy subjects were included as controls from the physical examination center of the above units in the same period. All the subjects filled out the allergic disease questionnaire under the guidance of doctors, and the allergen-specific immunoglobulin E (sIgE) of cats, dogs and horses of all subjects were detected by magnetic particle chemiluminescence system. The epidemiological characteristics of three animal allergens in different diseases, ages and regions were analyzed. Chi square test was used to analyze the frequency difference between groups, t test or Mann Whitney U test was used to test the distribution difference between two groups, and one-way ANOVA or Kruskal Wallis H test was used to compare the distribution difference between multiple groups. Bar chart, Venn-plot and radar chart were drawn to show the sensitization distribution characteristics. A small number of missing values caused by subjects' omission have been excluded during the analysis. Results: The 2 122 patients with allergic diseases were 57.35% male (1 217/2 122) and 40.95% female (869/2 122), and 1.70% (36/2 122) patients had loss of gender information. The age of patients with allergic diseases was 9.0 (6.0, 28.0) years, while that of healthy controls was 29.0 (13.0, 39.0) years old, and there were 1.7% (36/2 122) and 0.9% (2/222) subjects with missing age information, respectively. The proportion of caesarean section in allergic patients was significantly higher than that in healthy controls (31.4% vs. 17.6%,χ²=16.582,P<0.001) [2.5% (54/2 122) of the patient group and 5.4% (12/222) of the control group had missing birth mode information], and the proportion of patients with allergic diseases who reported that both parents had allergic diseases was significantly higher than that of the control group (35.7% vs. 9.5%, χ²=65.171,P<0.001). Patients with allergic diseases are mainly school-age (6-12 years old) and adolescents (12-18 years old). 16.4% of patients with allergic diseases were sensitized to cat dander, 10% and 6% to dog and horse dander. The sensitization rate of cat dander in patients with rhinitis, asthma, conjunctivitis, food allergy and atopic dermatitis was the highest (16.4%-21.6%), followed by dog dander (10.2%-15.2%). The prevalence of allergic rhinitis was the highest among different animal sensitized populations. The proportion of cat, dog and horse allergens sensitized at the same time is between 10%-15%, and the proportion of any two or more animal dander sensitized at the same time is about 45%. Animal allergens are associated with respiratory allergic diseases, especially allergic rhinitis with allergic conjunctivitis. There were significant differences in the distribution of positive rates of three animal allergens in different regions, and the highest positive rate of cat dander was found in all provinces of the country. Conclusion: The sensitization rate of animal dander allergens increased significantly, and the highest was in children and adolescents. Cat dander is the most common animal allergen, followed by dog. Different animals show obvious cross or common sensitization due to their high homology.

Observation of Resonance Structures in e^{+}e^{-}→π^{+}π^{-}ψ_{2}(3823) and Mass Measurement of ψ_{2}(3823)

Using a data sample corresponding to an integrated luminosity of 11.3  fb^{-1} collected at center-of-mass energies from 4.23 to 4.70 GeV with the BESIII detector, we measure the product of the e^{+}e^{-}→π^{+}π^{-}ψ_{2}(3823) cross section and the branching fraction B[ψ_{2}(3823)→γχ_{c1}]. For the first time, resonance structure is observed in the cross section line shape of e^{+}e^{-}→π^{+}π^{-}ψ_{2}(3823) with significances exceeding 5σ. A fit to data with two coherent Breit-Wigner resonances modeling the sqrt[s]-dependent cross section yields M(R_{1})=4406.9±17.2±4.5  MeV/c^{2}, Γ(R_{1})=128.1±37.2±2.3  MeV, and M(R_{2})=4647.9±8.6±0.8  MeV/c^{2}, Γ(R_{2})=33.1±18.6±4.1  MeV. Though weakly disfavored by the data, a single resonance with M(R)=4417.5±26.2±3.5  MeV/c^{2}, Γ(R)=245±48±13  MeV is also possible to interpret data. This observation deepens our understanding of the nature of the vector charmoniumlike states. The mass of the ψ_{2}(3823) state is measured as (3823.12±0.43±0.13)  MeV/c^{2}, which is the most precise measurement to date.

Observation of a State X(2600) in the π^{+}π^{-}η' System in the Process J/ψ→γπ^{+}π^{-}η'

Based on (10087±44)×10^{6}  J/ψ events collected with the BESIII detector, the process J/ψ→γπ^{+}π^{-}η^{'} is studied using two largest decay channels of the η^{'} meson, η^{'}→γπ^{+}π^{-} and η^{'}→ηπ^{+}π^{-}, η→γγ. A new resonance, which we denote as the X(2600), is observed with a statistical significance larger than 20σ in the π^{+}π^{-}η^{'} invariant mass spectrum, and it has a connection to a structure around 1.5  GeV/c^{2} in the π^{+}π^{-} invariant mass spectrum. A simultaneous fit on the π^{+}π^{-}η^{'} and π^{+}π^{-} invariant mass spectra with the two η^{'} decay modes indicates that the mass and width of the X(2600) state are 2618.3±2.0_{-1.4}^{+16.3}  MeV/c^{2} and 195±5_{-17}^{+26}  MeV, where the first uncertainties are statistical, and the second systematic.

Observation of J/ψ Electromagnetic Dalitz Decays to X(1835), X(2120), and X(2370)

Using a sample of about 10^{10}  J/ψ events collected at a center-of-mass energy sqrt[s]=3.097  GeV with the BESIII detector, the electromagnetic Dalitz decays J/ψ→e^{+}e^{-}π^{+}π^{-}η^{'}, with η^{'}→γπ^{+}π^{-} and η^{'}→π^{+}π^{-}η, have been studied. The decay J/ψ→e^{+}e^{-}X(1835) is observed with a significance of 15σ, and also an e^{+}e^{-} invariant-mass dependent transition form factor of J/ψ→e^{+}e^{-}X(1835) is presented for the first time. The intermediate states X(2120) and X(2370) are also observed in the π^{+}π^{-}η^{'} invariant-mass spectrum with significances of 5.3σ and 7.3σ. The corresponding product branching fractions for J/ψ→e^{+}e^{-}X, X→π^{+}π^{-}η^{'} [X=X(1835), X(2120), and X(2370)] are reported.

[Lipoprotein apheresis in patients with familial hypercholesterolemia: a single center research]

Objective: We evaluated the safety and efficacy of lipoprotein apheresis (LA) in patients with familial hypercholesterolemia (FH) who can't reach low-density lipoprotein cholesterol(LDL-C) target goals with the maximal tolerated dose of lipid-lowering agents. Methods: This was a retrospective cross-sectional study. Between February 2015 and November 2019, patients with FH who were admitted in Fuwai hospital and treated with LA were consecutively enrolled. Based on intensive lipid-lowering agents, these patients received LA by double filtration plasma pheresis (DFPP) method. The changes of lipid levels such as LDL-C and lipoprotein(a)[Lp(a)] were compared before and after LA treatment, and the changes of immunoglobulin (Ig) concentration and LA-related adverse effects were also discussed. Results: A total of 115 patients with FH were enrolled in this study, of which 8 cases were homozygous FH and 107 cases were heterozygous FH. The age was (43.9±12.2) years and there were 75 (65.2%) males, and 108 (93.8%) with coronary artery disease. For pre-and immediately after LA treatment, the LDL-C was (5.20±2.94) mmol/L vs. (1.83±1.08) mmol/L, Lp(a) concentration was 428.70(177.00, 829.50)mg/L vs. 148.90(75.90, 317.00) mg/L (P<0.001), with a decrease of 64.2% and 59.8% respectively. The levels of IgG and IgA measured 1 day after LA treatment were both in the normal range and IgM concentration was below the reference value, the reductions of which were 15.1%, 25.0% and 58.7% respectively (P<0.001). Six patients had mild symptoms of nausea, hypotension dyspnea and palpitation, the symptoms were relieved by symptomatic treatment. Conclusion: For patients with FH who do not achieve LDL-C target goal with the maximal tolerated lipid-lowering agents, especially those with elevated Lp(a) levels, LA, which can significantly further reduce LDL-C and Lp(a) levels, is an effective and safe option.

Hypertriton Production in p-Pb Collisions at sqrt[s_{NN}]=5.02 TeV

The study of nuclei and antinuclei production has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic collisions. The first measurement of the production of _{Λ}^{3}H in p-Pb collisions at sqrt[s_{NN}]=5.02  TeV is presented in this Letter. Its production yield measured in the rapidity interval -1<y<0 for the 40% highest-multiplicity p-Pb collisions is dN/dy=[6.3±1.8(stat)±1.2(syst)]×10^{-7}. The measurement is compared with the expectations of statistical hadronization and coalescence models, which describe the nucleosynthesis in hadronic collisions. These two models predict very different yields of the hypertriton in charged particle multiplicity environments relevant to small collision systems such as p-Pb, and therefore the measurement of dN/dy is crucial to distinguish between them. The precision of this measurement leads to the exclusion with a significance larger than 6.9σ of some configurations of the statistical hadronization model, thus constraining the theory behind the production of loosely bound states at hadron colliders.

Effect of dietary protein and energy intake on embryonic survival and gene expression in the uterine endometrium of early pregnant gilts

Porcine embryonic loss during early gestation is a serious problem in swine production. Improving embryonic survival can be achieved by maternal manipulation. Protein and energy are two major components of the diet, which play decisive roles in embryonic survival. This study was performed to evaluate the effects of enhancing maternal protein or energy intake on embryonic survival during early gestation in gilts and to explore the underlying mechanism. From day (d) 0 to 30 of gestation, 40 gilts (Landrace × York) were randomly allocated to 5 diets according to daily intake of low (L, National Research Council (NRC) recommendation for gestation gilts), medium (M, 20% higher than NRC) or high (H, 40% higher than NRC) CP or metabolisable energy (ME) (L_CPL_ME, M_CPL_ME, H_CPL_ME, L_CPH_ME, H_CPH_ME). Gilts were sacrificed on d 30 of gestation, and number of foetuses and corpora lutea, embryonic survival rate, uterine weight, and total volume of allantoic fluid were recorded or calculated. Gene expression was determined by Quantitative Real-time PCR (qPCR), western blot or immunohistochemistry. Results showed that increasing protein or ME intake significantly increased embryonic survival rate. Compared with diet L_CPL_ME, plasma progesterone (P4) concentration in diet L_CPH_ME increased at d 14 and d 30 of gestation. Progesterone receptor (PGR) was found not to be expressed in the epithelia but was strongly expressed in the stroma of the endometrium. Increasing protein or ME intake did not alter PGR expression in the endometrium. There was also no change in the amount of P4, hepatocyte growth factor, and fibroblast growth factor-7 in the endometrium. The mRNA abundance of cationic amino acid transporter 1 in the endometrium in diet L_CPH_ME and H_CPH_ME was significantly lower than in diet L_CPL_ME. Diet H_CPL_ME showed a tendency to increase neutral amino acid transporter 1 mRNA expression in the endometrium compared to diet L_CPL_ME (P = 0.087). In conclusion, increasing maternal protein or ME intake had a positive effect on the embryonic survival. Increased protein intake by 20 or 40% did not alter plasma P4 level, but increasing ME intake by 40% improved plasma P4 concentration at d 14 and 30 of gestation. Increasing maternal protein or ME intake did not induce PGR expression in the endometrium. Maternal protein and energy intake likely mediate transportation of cationic and neutral amino acids from mother to foetus to affect embryonic survival and development.

Polarization of Λ and Λ[over ¯] Hyperons along the Beam Direction in Pb-Pb Collisions at sqrt[s]_{NN}=5.02 TeV

The polarization of the Λ and Λ[over ¯] hyperons along the beam (z) direction, P_{z}, has been measured in Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV recorded with ALICE at the Large Hadron Collider (LHC). The main contribution to P_{z} comes from elliptic flow-induced vorticity and can be characterized by the second Fourier sine coefficient P_{z,s2}=⟨P_{z}sin(2φ-2Ψ_{2})⟩, where φ is the hyperon azimuthal emission angle and Ψ_{2} is the elliptic flow plane angle. We report the measurement of P_{z,s2} for different collision centralities and in the 30%-50% centrality interval as a function of the hyperon transverse momentum and rapidity. The P_{z,s2} is positive similarly as measured by the STAR Collaboration in Au-Au collisions at sqrt[s_{NN}]=200  GeV, with somewhat smaller amplitude in the semicentral collisions. This is the first experimental evidence of a nonzero hyperon P_{z} in Pb-Pb collisions at the LHC. The comparison of the measured P_{z,s2} with the hydrodynamic model calculations shows sensitivity to the competing contributions from thermal and the recently found shear-induced vorticity, as well as to whether the polarization is acquired at the quark-gluon plasma or the hadronic phase.

Observation of the Singly Cabibbo Suppressed Decay Λ_{c}^{+}→nπ^{+}

The singly Cabibbo-suppressed decay Λ_{c}^{+}→nπ^{+} is observed for the first time with a statistical significance of 7.3σ by using 3.9  fb^{-1} of e^{+}e^{-} collision data collected at center-of-mass energies between 4.612 and 4.699 GeV with the BESIII detector at BEPCII. The branching fraction of Λ_{c}^{+}→nπ^{+} is measured to be (6.6±1.2_{stat}±0.4_{syst})×10^{-4}. By taking the upper limit of branching fractions of Λ_{c}^{+}→pπ^{0} from the Belle experiment, the ratio of branching fractions between Λ_{c}^{+}→nπ^{+} and Λ_{c}^{+}→pπ^{0} is calculated to be larger than 7.2 at the 90% confidence level, which disagrees with most predictions of the available phenomenological models. In addition, the branching fractions of the Cabibbo-favored decays Λ_{c}^{+}→Λπ^{+} and Λ_{c}^{+}→Σ^{0}π^{+} are measured to be (1.31±0.08_{stat}±0.05_{syst})×10^{-2} and (1.22±0.08_{stat}±0.07_{syst})×10^{-2}, respectively, which are consistent with previous results.

Measurement of the Groomed Jet Radius and Momentum Splitting Fraction in pp and Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV

This article presents groomed jet substructure measurements in pp and Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV with the ALICE detector. The soft drop grooming algorithm provides access to the hard parton splittings inside a jet by removing soft wide-angle radiation. We report the groomed jet momentum splitting fraction, z_{g}, and the (scaled) groomed jet radius, θ_{g}. Charged-particle jets are reconstructed at midrapidity using the anti-k_{T} algorithm with resolution parameters R=0.2 and R=0.4. In heavy-ion collisions, the large underlying event poses a challenge for the reconstruction of groomed jet observables, since fluctuations in the background can cause groomed parton splittings to be misidentified. By using strong grooming conditions to reduce this background, we report these observables fully corrected for detector effects and background fluctuations for the first time. A narrowing of the θ_{g} distribution in Pb-Pb collisions compared to pp collisions is seen, which provides direct evidence of the modification of the angular structure of jets in the quark-gluon plasma. No significant modification of the z_{g} distribution in Pb-Pb collisions compared to pp collisions is observed. These results are compared with a variety of theoretical models of jet quenching, and provide constraints on jet energy-loss mechanisms and coherence effects in the quark-gluon plasma.

Measurement of the Cross Section for e^{+}e^{-}→Hadrons at Energies from 2.2324 to 3.6710 GeV

Based on electron-positron collision data collected with the BESIII detector operating at the Beijing Electron-Positron Collider II storage rings, the value of R≡σ(e^{+}e^{-}→hadrons)/σ(e^{+}e^{-}→μ^{+}μ^{-}) is measured at 14 center-of-mass energies from 2.2324 to 3.6710 GeV. The resulting uncertainties are less than 3.0% and are dominated by systematic uncertainties.

Incidence, clinical correlates and associated outcomes of dementia in heart failure: a population-based cohort study

Funding Acknowledgements

Type of funding sources: None.

Background

Dementia, in the setting of heart failure (HF), portends poorer outcomes and poses great challenges in its clinical management.

Purpose

We investigated the incidence, types, clinical correlates, and the prognostic impact of dementia in a population-based cohort of patients with HF. Further, we examined the interactions of age and sex, and education status with dementia incidence.

Methods

The previously validated Hong Kong Clinical Data Analysis Reporting System (CDARS), a territory-wide database was interrogated to identify patients with HF (N= 202,121) from 1995 to 2018. Associations of clinical correlates with incident dementia and its risk with all-cause mortality were assessed using competing risk/multivariable Cox regression models where appropriate.

Results

Among a total cohort aged ≥18 years with HF (mean age: 75.3 ± 13.0 years, 51.3% women), new-onset dementia occurred in 22,145 (11.0%) over a median follow-up of 5.5 years. Alzheimer’s disease occurred in 27.0%; vascular dementia (18.1%) and unspecified dementia (in 55.1%). Age-standardized rate of dementia incidence in women was 1297 (95%CI, 1276-1318) (vs. 744, 95%CI, 723-765) per 10000 population in men. Other independent predictors of dementia include: Increasing age (HR 1.08), Female sex (HR 1.19), Nil/&lt; primary (vs tertiary) education (HR 1.29), Parkinson’s disease (HR 1.73), head injury (HR 1.37), peripheral vascular disease (HR 1.31), stroke (HR 1.29), depression (HR 1.18), alcohol intake (HR1.17), anaemia (HR 1.14), hypertension (HR 1.08), among other common comorbidities in HF (Figure 1A).

Notably, a significant interaction (p &lt; 0.001) between age and sex on dementia incidence was observed, such that women in all age groups were observed to have higher sHR compared to men (Figure 1B). After accounting for competing risk, dementia was not associated with adjusted hazard of all-cause mortality.

Conclusions

Female sex, lower socioeconomic status, increasing age and common comorbidities were associated with higher hazards of incident dementia. Abstract Figure 1A and Figure 1B

[A brief introduction of Ayurvedic medical classics]

Ayurveda can be traced back to 3000BC. It is the principal part of traditional medicine in India and other South Asian countries. It was divided into four historical periods according to the academic circle in India, ie. the Vedic period, the Samhita period, the Sangraha period and the modern period. The literature in the Vedic period mainly included Vedic Samhitas Brahmanas, Ramayana, Mahabharata. In the Samhita period, the "BrihatTrayee", namely, Caraka Samhita, Susruta Samhita and Astanga Hrdaya Samhita were published, indicating that Ayurveda had developed into a full-fledged medical system. In the Sangraha period, the "Laghu Trayee", namely, Madhava Nidana, Sarangadhara Samhita and Bhava Prakasa were published. At this time, a large number of annotated texts for these medical books emerged, which kept driving Ayurveda improvements. Since the modern period, Ayurvedic classical works were rearranged, edited and translated into different languages as cultural heritage, drawing attention worldwide. While the research to these works has been conducted widely in China, they are still short of systematic and professional translation and in-depth studies. This paper attempts to introduce the literature related to Ayurveda systematically, to pave the way for further research of Ayurvedic literature in the field of traditional Chinese medicine.

[Effects of continuous goal-directed analgesia on fluid resuscitation of massive burn patients during shock]

Objective: To investigate the effects of continuous goal-directed analgesia on fluid resuscitation during shock stage in patients with massive burns, providing a basis for rational optimization of analgesia protocols in patients with burn shock. Methods: A retrospective case series study was conducted. One hundred and thirty-six patients with massive burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital from January 2015 to December 2020, and the patients were divided into continuous analgesia (CA) group (68 cases,with average age of 44 years old) and intermittent analgesia (IA) group (68 cases,with average age of 45 years old) according to whether sufentanil injection was continuously used for intravenous analgesia during the shock stage. The patients in the 2 groups were predominantly male. Before and at 72 h of treatment, the severity of disease and trauma pain of patients in the 2 groups were scored by the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and the visual analogue scale (VAS). Hematocrit, heart rate, mean arterial pressure (MAP), central venous pressure (CVP), oxygen saturation in central venous blood (ScvO2), rehydration coefficient, blood lactate value, hourly urine output, and the adverse reactions such as hypotension, nausea, vomiting, dizziness, skeletal muscle tonicity, respiratory depression, bradycardia, pruritus, and drug addiction of patients in the 2 groups during the treatment were recorded at the 1st, 2nd, and 3rd 24 h post-injury. Data were statistically analyzed with analysis of variance for repeated measurement, paired or independent sample t test, Bonferroni correction,chi-square test and Mann-Whitney U test. Results: Before treatment, APACHE Ⅱ and VAS scores of patients in the 2 groups were close (with t values of -0.67 and 0.32, respectively, P>0.05); At 72 h of treatment, APACHE Ⅱ and VAS scores of patients in CA group were 8.5±2.2 and 2.5±1.6, both of which were significantly lower than (15.2±3.0) and (7.9±2.0) of patients in IA group, respectively (with t values of -14.94 and -17.46, respectively, P<0.01). Compared with the pre-treatment period, the APACHE Ⅱ and VAS scores of patients in IA group decreased significantly at 72 h of treatment (with t values of 11.35 and 30.59, respectively, P<0.01); the changes in APACHE Ⅱ and VAS scores of patients at 72 h of treatment in comparison with those of patients before treatment in CA group were all similar to those of patients in IA group (with t values of 4.00 and 4.82, respectively, P<0.01). Compared with those of patients in IA group, there were no significant changes in CVP, hematocrit, heart rate, ScvO2, and MAP of patients in CA group at all three 24 h post-injury (with t values of <0.01, 0.12, 2.10, 1.55, 0.03; 0.13, 0.22, <0.01, 0.17, 0.49; 0.63, 0.06, 0.04, 2.79, and 2.33, respectively, P>0.05). Compared with those of patients in IA group at the 1st 24 h post-injury, CVP, ScvO2 and MAP of patients were significantly higher at the 2nd and 3rd 24 h post-injury (with t values of -10.10, -9.31, -8.89; -10.81, -4.65, and -9.43, respectively, P<0.01), and the heart rate of patients was significantly lower at the 2nd and 3rd 24 h post-injury (with t values of 7.53 and 7.78, respectively, P<0.01), and the hematocrit of patients decreased significantly only at the 3rd 24 h post-injury (t=15.55, P<0.01); the changes of CVP, ScvO2, MAP and heart rate of patients at the 2nd and the 3rd 24 h post-injury, and HCT of patients at the 3rd 24 h post-injury, in comparison with those of patients at the 1st 24 h post-injury in CA group were similar to those of patients in IA group (with t values of -12.25, -10.24, -8.99, 9.42, -8.83, -7.53, -11.57, 10.44, and 12.91, respectively, P<0.01). Compared with those of patients in IA group, the rehydration coefficient of patients in CA group was significantly higher only at the 3rd 24 h post-injury (t=5.60, P<0.05), blood lactate value of patients in CA group was significantly lower at the 1st and 2nd 24 h post-injury (with t values of 4.32 and 14.52, respectively, P<0.05 or P<0.01), the hourly urine output of patients in CA group increased significantly at the 1st, 2nd, and 3rd 24 h post-injury (with t values of 24.65, 13.12, and 5.63, respectively, P<0.05 or P<0.01). Compared with the those of patients at the 1st 24 h post-injury, the rehydration coefficient of patients in IA group decreased significantly at the 2nd and the 3rd 24 h post-injury (with t values of 33.98 and 36.91, respectively, P<0.01), the blood lactate values of patients in IA group decreased significantly at the 2nd and the 3rd 24 h post-injury (with t values of 8.20 and 11.68, respectively, P<0.01), and the hourly urine output of patients in IA group was significantly increased at the 2nd and the 3rd 24 h post-injury (with t values of -3.52 and -5.92, respectively, P<0.01); the changes of rehydration coefficients and blood lactate values of patients at the 2nd and the 3rd 24 h post-injury in comparison with those of patients at the 1st 24 h post-injury in CA group were similar to those of patients in IA group (with t values of 35.64, 33.64, 9.86, and 12.56, respectively, P<0.01), but hourly urine output of patients in CA group increased significantly only at the 3rd 24 h compared with that of patients at the 1st 24 h post-injury (t=-3.07, P<0.01). Adverse reactions such as hypotension, nausea, vomiting, dizziness, bradycardia, and pruritus occurred rarely in patients of the 2 groups, and none of the patients had skeletal muscle tonicity, respiratory depression, or drug addiction. The incidence of adverse reactions of patients in CA group was similar to that in IA group (χ2=0.08, P>0.05). Conclusions: Continuous goal-directed analgesia can effectively relieve pain and improve vital signs of patients with large burns. Meanwhile it has little impact on volume load, which can assist in correcting ischemia and hypoxia during the shock period and help patients get through the shock period smoothly.
