世界核心医学期刊文摘（眼科学分册） 2005年第7期1卷 58-59页

作者： Assink J.J.M. klaver c.c.w. Houwing- Duisterm-aat J. J. P.T.V.M. De Jong 王海燕 Netherlands Ophthal. Res. Institute Meibergdreef47 1105 BA Amsterdam Netherlands

Objective: To assess the extent of heterogeneity of the genetic risk of age- related macular disease (AMD) among families. Design: case- controlled population- based familial aggregation study. Participants: Participants comprised 190 first- degree relatives of 65 case probands and 347 relatives of 100 control probands. All probands had been identified from the baseline phase of the Rotterdam Study in The Netherlands. Methods: A family score was computed for each family based on the presence and type of macular disease, the expected risk of disease, and the number, extent of kinship, and age of all family members. Main Outcome Measures: Presence and stage of AMD as diagnosed on fundus photographs, family score, and logistic regression coefficient. Results: The family score of case families showed a peak of approximately 0 with a skewed tail (14% of families) of higher than expected risks of disease toward a maximum of 2.9. The family score of control families centered on 0, apart from 1 outlier. The risk of AMD increased significantly with higher family scores (β =1.34; Pconclusions: The heterogeneity of genetic risk among AMD families is considerable, and the proportion of high- risk families is relatively small. The family score method is relevant for genetic counseling as well as for implementation in studies of genetic dissection of AMD.

孔源性视网膜脱离的遗传风险:一项家族聚集性研究

世界核心医学期刊文摘(眼科学分册) 2006年第1期 29-29页

作者： Go S.L. Hoyng c.B. klaver c.c.w. 宋虎平 Department of Ophthalmology 813 University Medical Centre Nijmegen PO Box 9101 Nijmegen 6500 HB Netherlands Dr

Objective: To investigate the magnitude of the genetic risk of nonsyndromic rhegmatogenous retinal detachments (RRDs) in a familial aggregation study. Design: Two hundred three consecutive patientswith RRD and 461 controlswithout RRD were ascertained at the Department of Ophthalmology of the University Medical centre Nijmegen in Nijmegen, the Netherlands. Data on family composition, history of RRD, and presence of other risk factors in siblings and offspring were collected by means of a questionnaire. Diagnosis of RRD was confirmed by evaluation of medical records. Results: One hundred eightyone patients (89.2% of those eligible) and 408 controls (88.5% of invited controls) with 1090 and 2345 relatives, respectively, were included in the analysis. Thirteen familial RRDs (1.2% )-were diagnosed in 10 case probands and 9 RRDs (0.4% ) in 8 control probands. Siblings and offspring of cases had a higher incidence of RRD independent of age, sex, and myopia. The cumulative lifetime risk of RRD was 7.7% for relatives of cases and 3.0% for relatives of controls, yielding a risk ratio of 2.6 (95% confidence interval, 1.1-6.2). conclusions: Familial occurrence of RRD is a risk factor for RRD. Genetic factors apart from myopia may explain the increased familial risk.

Background:Tau vaccination and administration of anti-tau antibodies can prevent pathology and cognitive impairment in transgenic mouse models of tauopathy,suggesting that therapies which increase anti-tau antibodies might slow the development and/or progression of Alzheimer’s disease(AD).The extent to which individuals with no cognitive impairment(NcI)possess serum anti-tau antibodies,and whether their concentrations of these antibodies differ from anti-tau antibody levels in persons with mild cognitive impairment(McI)or AD,are *** studies measuring these antibodies did not account for antibody polyvalent binding,which can be extensive,nor that antibody binding to phosphorylated tau peptides could be due to binding to non-phosphorylated epitopes on those ***:An ELISA controlling for these factors was used to measure the specific binding of serum IgG and IgM to phosphorylated(“pTau;”phosphorylated at Serine-199 and Serine-202)and non-phosphorylated(“non-pTau”)tau 196-207 in subjects with NcI,McI,or AD(n=10/group).Between-group differences in these antibody levels were evaluated for statistical significance,and correlations were examined in pooled data from all subjects between these antibody levels and subject age,global cognitive functioning,and NFT ***:Specific IgG binding to pTau and non-pTau was detected in all subjects except for one NcI *** IgM binding was detected to pTau in all subjects except for two AD patients,and to non-pTau in all *** pTau IgG was increased in McI subjects by 53% and 70% *** and NcI subjects respectively(both pwhile no significant differences were found between groups for non-pTau IgG(p=0.052),pTau IgM,or non-pTau ***-pTau IgG was negatively associated with global cognition(Spearman rho=−0.50).conclusions:Specific binding of serum IgG and IgM to phosphorylated and non-phosphorylated tau may be present in older persons regardless of their cognitive *** IgG

The first search for the doubly heavy Ωbc0baryon and a search for the Ξbc0baryon are performed using pp collision data collected via the LHcb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 *** baryons are reconstructed via their decays to ∧c+π-andΞc+π-.No significant excess is found for invariant masses between 6700 and 7300 MeV/c2,in a rapidity range from2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** limits are set on the ratio of the Ωbc0andΞbc0production cross-section times the branching fraction to ∧c+π-（Ξc+π-） relative to that of the ∧b0（Ξb0） baryon,for different lifetime hypotheses,at 95% confidence *** upper limits range from 0.5×10-4to 2.5×10-4for theΩbc0→∧c+π-(Ξbc0→∧c+π-) decay,and from 1.4×10-3to 6.9×10-3for the Ωbc0→Ξc+π-(Ξbc0→Ξc+π-) decay,depending on the considered mass and lifetime of the Ωbc0(Ξbc0) baryon.

A search for the doubly charmed baryon ?cc+with the decay mode ?cc+→Ξc+K-π+is performed using proton-proton collision data at a centre-of-mass energy of 13 TeV collected by the LHcb experiment from 2016 to 2018, corresponding to an integrated luminosity of 5.4 fb-1. No significant signal is observed within the invariant mass range of 3.6 to 4.0 GeV/c2. Upper limits are set on the ratio R of the production cross-section times the total branching fraction of the ?cc+→Ξc+K-π+decay with respect to the Ξcc++→Λc+K-π+π+decay. Upper limits at 95% credibility level for R in the range 0.005 to 0.11 are obtained for diferent hypotheses on the ?cc+mass and lifetime in the rapidity range from 2.0 to 4.5 and transverse momentum range from 4 to 15 GeV/c.

The production of ■baryons in proton-proton collisions at a centre-of-mass energy of √s = 13 TeV is measured in the transverse-momentum range 4c and the rapidity range2.0correspond to an integrated luminosity of 1.7fb^-1,recorded by the LHcb experiment during *** ratio of the ■ production cross-section times the branching fraction of the■→∧^+cK^-π^+ π^+decay relative to the prompt ∧^+c production cross-section is found to be(2.22±0.27±0.29)×10^-4,assuming the central value of the measured lifetime,where the first uncertainty is statistical and the second systematic.
