A first search for the Ξ_(bc)^(+)J/ψΞ_(c)^(+) decay is performed by the LHCb experiment with a data sample of proton-proton collisions, corresponding to an integrated luminosity of 9 fb−1 recorded at centre-of-mass energies of 7, 8, and 13 teV. two peaking structures are seen with a local (global) significance of 4.3(2.8) and 4.1(2.4) standard deviations at masses of 6571 and 6694 MeV/c2, respectively. Upper limits are set on the Ξ+bc baryon production cross-section times the branching fraction relative to that of the B+c→J/ψD+s decay at centre-of-mass energies of 8 and 13 teV, in the Ξ+bc and in the B+c rapidity and transverse-momentum ranges from 2.0 to 4.5 and 0 to 20GeV/c, respectively. Upper limits are presented as a function of the Ξ+bc mass and lifetime.

目的:观察尿酸对大鼠脊髓损伤后损伤段半胱氨酸蛋白酶3的表达及神经细胞凋亡的影响。方法:实验于2005-07/12在同济医院矫形外科实验室完成。选用雌性SD大鼠55只,按随机数字表法分为3组,空白对照组5只,脊髓损伤组和尿酸处理组各25只。脊髓损伤组和尿酸处理组大鼠用改良的allen’s打击法造脊髓损伤模型。空白对照组大鼠单纯切除椎板,不打击脊髓。脊髓损伤组和尿酸处理组大鼠分别于术后8h,24h,72h,7d,14d取材,每时点处死5只大鼠;空白对照组大鼠于术后8h处死取材。对损伤部位脊髓进行病理形态学观察;采用原位末端标记法标记凋亡细胞,计算凋亡细胞指数=凋亡细胞核数/总细胞核数;用免疫组化染色检测半胱氨酸天冬氨酸蛋白酶3阳性细胞。结果:纳入55只大鼠,全部进入结果分析,无脱失。①各组大鼠脊髓组织学检查结果比较:空白对照组大鼠脊髓未见出血、组织变性坏死等表现。与脊髓损伤组相比,尿酸处理组大鼠损伤脊髓出血坏死减少,炎性细胞浸润减轻。②各组大鼠脊髓组织半胱氨酸天冬氨酸蛋白酶3阳性细胞数及神经细胞凋亡指数比较:相同时点尿酸处理组大鼠的神经细胞凋亡指数和半胱氨酸天冬氨酸蛋白酶3阳性细胞数均显著低于脊髓损伤组(t=3.057～6.965,P<0.05)。结论:尿酸可以抑制脊髓神经细胞凋亡及半胱氨酸天冬氨酸蛋白酶3表达,对损伤脊髓组织具有保护作用。

PSORS1 on chromosome 6p21.3, which contains the MHC, is a major susceptibility locus for psoriasis vulgaris. this region is characterized by strong linkage disequilibrium and contains the corneodesmosin (CSDN) gene, an attractive candidate for psoriasis susceptibility based on its putative biological function in keratinocyte adhesion, and HLA-Cw6, an established marker for psoriasis susceptibility. We compared two genetically in-dependent populations in order to define the major psoriasis susceptibility gene, a British Caucasian population comprising parent-offspring trios analysed by the transmission disequilibrium test (tDt) and a Japanese case-control population. All individuals were investigated for CDSN polymorphism (+619, +1236, +1240 and +1243) and HLA-C association. Our data confirms strong association with HLA-Cw6 and CDSN allele 5 (+619t, +1240G, +1243C) in the Caucasian cohort (tDt, P=5.4×10-6) and in addition defines this region further by identifying a high-risk CDSN haplotype (allele 5 and +1236t, P=8.5×10-8). In contrast no association was observed in the Japanese cohort for any HLA-C or CDSN alleles. this data supports a role for the CDSN gene in Caucasian populations with psoriasis. However the lack of association with HLACw6 and CDSN alleles in Japanese psoriasis patients may be because Japanese patients exhibit a form of psoriasis similar to late onset or type II psoriasis vulgaris in contrast to early onset or type I disease characterizing our Caucasian population.

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.

Etablierung eines tierexperimentellen Modells des hepatozellularen Karzinoms (HCC) bei ACI-Ratten durch den Einsatz von allogenischer Implantationstechnik und Beobachtung durch die MR-Untersuchung. Bei einer mannlichen ACI-Ratte wurde die tumorzellen von Morris Hepatoma 3924A in die Flanke subkutan injiziert. 13 tage danach erfolgte die Implantation eines soliden tumorfragments (1 mm 3 ) aus dem gewachsenen tumor subkapsular in den linkem Leberlappen bei anderen mannlichen ACI-Ratten (n=12). 14 tage nach Implantation wurden die tumorvolumina kernspintomographisch bestimmt. 14 tage nach Implantation wurde der isolierte und solide Lebertumor bei allen ACI-Ratten kernspintomographisch beobachtet. Das durchschnittliche tumorvolumen betrug hierbei 0,090±0,008 cm 3 . Die Angehrate der tumorimplantation war 100 %. Eine auffallende Hypointensitat der Lasion im Vergleich zum umgebenden Lebergewebe im t1w-Bild und eine massig vermehrte Signalintensitat im t2w-Bild mit inhomogener Struktur waren bei allen implantierten Ratten erkennbar. Mit einer guten Angehrate des Implantations und geeignetem tumorwachstumsverhalten steht dieses Verfahren zur Etablierung eines tiermodells des HCCs zur Verfugung. Es ist einfach zu kontrollieren und leicht reproduzierbar.

to assess the visual outcomes of patients with stage 4A retinal detachments (RDs) from retinopathy of prematurity (ROP). Retrospective review of a consecutive case series of children referred to the pediatric retina service of Associated Retinal Consultants, Royal Oak, Michigan. Forty- five eyes of 39 children. the stage of RD for each patient was determined during an examination under anesthesia. All patients underwent a lens- sparing pars plana vitrectomy (PPV) with membrane peeling. Postoperative anatomic status was determined by ophthalmoscopy either during an office examination or during an examination under anesthesia. Visual outcomes were ascertained by consulting pediatric ophthalmologists using either teller or allen acuities. Anatomic and visual outcomes. Formalized visual acuity (VA) measurement was performed in 23 eyes of 20 children, and was not performed in 22 eyes of 19 children. All 23 eyes that were formally tested had successful retinal reattachment. the macula appeared to be normal and without distortion in 19 of 23 eyes (83% ) during the follow- up period. Average logarithm of the minimum angle of resolution VA was 20/58. three eyes had acuities of 20/200, and 4 had acuities of 20/100. All other eyes were 20/80 or better. Average age at time of VA was 3.51 years. Patients with ROP and stage 4A RDs can be treated successfully with respect to anatomic and visual outcome utilizing lens- sparing PPV.
