水化疗法预防造影剂肾病的效果研究

目的研究水化疗法预防造影剂肾病的效果。方法随机选取2016年6月～2018年6月我院收治的造影剂肾病高危患者60例,依据预防方法分为两组,即氯化钠水化疗法组和复方氯化钠水化疗法组,每组30例,统计分析两组患者的Cr、pH、GFR、HCO3~-、K~+水平、造影剂肾病、二级终点事件发生情况。结果复方氯化钠水化疗法组患者的Cr水平显著低于氯化钠水化疗法组(P0.05),pH、GFR水平均显著高于氯化钠水化疗法组(P0.05),造影剂肾病、二级终点事件发生率为3.3%(1/30)、0,均显著低于氯化钠水化疗法组的13.3%(4/30)、10.0%(3/30)(P0.05)。结论复方氯化钠水化疗法预防造影剂肾病的效果较氯化钠水化疗法好,值得在临床推广。     

A novel compound heterozygosity in Southern China: IVS-II-5 (G > C) and IVS-II-672 (A > C)

β-Thalassemia (β-thal) is a common hereditary anemia due to decreased or absent synthesis of the β-globin chains. Here, we report a patient found to be a novel compound heterozygote for the rare IVS-II-5 (G?>?C) (NG_000007.3: g.71044G?>?C) and IVS-II-672 (A?>?C) (NG_000007.3: g.71711A?>?C) mutations, which may be silent mutations that are associated with consistent residual output of β chains, normal red blood cell (RBC) indices and normal or borderline Hb A₂ levels.     

Effects of visual-haptic asynchronies and loading-unloading movements on compliance perception

Spring compliance is perceived by combining the sensed force exerted by the spring with the displacement caused by the action (sensed through vision and proprioception). We investigated the effect of delay of visual and force information with respect to proprioception to understand how visual-haptic perception of compliance is achieved. First, we confirm an earlier result that force delay increases perceived compliance. Furthermore, we find that perceived compliance decreases with a delay in the visual information. These effects of delay on perceived compliance would not be present if the perceptual system would utilize all force-displacement information available during the interaction. Both delays generate a bias in compliance which is opposite in the loading and unloading phases of the interaction. To explain these findings, we propose that information during the loading phase of the spring displacement is weighted more than information obtained during unloading. We confirm this hypothesis by showing that sensitivity to compliance during loading movements is much higher than during unloading movements. Moreover, we show that visual and proprioceptive information about the hand position are used for compliance perception depending on the sensitivity to compliance. Finally, by analyzing participants’ movements we show that these two factors (loading/unloading and reliability) account for the change in perceived compliance due to visual and force delays.

腕踝针对腰痛止痛作用的针刺点特异性随机对照临床研究

目的研究腕踝针的"针刺点"与"身体分区"的对应关系是否具有特异性,即腕踝针针刺点作用的特异性。方法采用随机对照临床试验,将90例急性腰痛患者随机分为三组,每组30例。三组受试者均采用腕踝针治疗1次,留针30 min。特异针刺点组根据腕踝针"按身体分区选择针刺点"的理论针刺下6或下5针刺点;非特异针刺点1组和2组分别针刺下2和上5针刺点。治疗前3 min和治疗过程第5、10、15和第30 min,分别用简式Mc Gill疼痛问卷(SF-MPQ)评价受试者活动腰部时疼痛情况,用重复改良的Schober试验(MMS)观察腰椎活动度,用预期和治疗信任度问卷(ETCS)评价三组患者治疗前后预期的变化。结果三组治疗前SFMPQ、MMS和ETCS各项差异均无统计学意义(P0.05)。三组SF-MPQ评分在第5、10、15和30 min与治疗前相比均降低(P0.05)。在第5、10和15 min,特异针刺点组的SF-MPQ多项评分(除PPI外)与治疗前的差值高于非特异针刺点1组和2组(P0.05)。治疗30 min后,特异针刺点组的SF-MPQ所有项目评分与治疗前的差值均高于非特异针刺点1组和2组(P0.05)。三组MMS治疗后均高于治疗前(P0.05),特异针刺点组MMS治疗后与治疗前差值高于非特异针刺点1组和2组(P0.05)。特异针刺点组的ETCS所有项目评分在治疗后与治疗前相比均升高(P0.05)。非特异针刺点1组和2组的ETCS所有项目评分在治疗后与治疗前相比,差异无统计学意义(P0.05)。结论腕踝针针刺点对急性腰痛具有止痛和改善腰椎前屈活动度作用,具有一定的特异性。     

Two-stage maxillary distraction osteogenesis using a modified external device: clinical outcome and complications

Rigid external distraction is currently used to correct severe maxillary hypoplasia. The purpose of this retrospective study was to present the clinical results and complications of a two-stage surgical approach using a modified external distraction system that consists of maxillary distraction and then maxillary fixation. We treated eight patients with cleft lip and palate in this way from 2016 to 2018. Lateral cephalograms taken before the first operation, after distraction, two weeks after the second operation, and one year after treatment were used to examine maxillofacial morphology. Velopharyngeal function was evaluated by a speech therapist. The mean movements of the maxilla forwards and downwards at Point A were 12.0 mm and 8.0 mm at the completion of distraction and those at Point B were 5.0 mm backwards and 9.7 mm downwards. Mouth opening was limited at this time, and was relieved after maxillary fixation. The mean relapse one year postoperatively was 24.3% horizontally and 52.5% vertically. Velopharyngeal function was unchanged by the operation. We conclude that the method has advantages that include the short duration of wearing distractors and increased acceptance by patients. The modified external device advanced the midface sufficiently.     

HBB: c.316-125A>G and HBB: c.316-42delC: Phenotypic Evaluations of Two Rare Changes in the Second Intron of the HBB Gene

We report two very rare changes in the second intron of the HBB gene, a substitution at nucleotide (nt) 726 [IVS-II-726 (A>G) (β⁺), NM_000518, HBB: c.316-125A>G] and a deletion of a cytosine at nt 809 [IVS-II-809 (–C) (β), NM_000518, HBB: c.316-42delC] identified during the screening program for hemoglobinopathies in the resident Sicilian population. The purpose of this study was to evaluate the clinical implication of these rare changes, particularly in coinheritance with known mutations in the globin clusters, in order to conduct an appropriate genetic counseling for at-risk couples. Molecular analysis detected the first rare nt substitution in two cases in simple heterozygosity and in two cases in association with other known mutations on globin genes, while the deletion was identified in a pregnant woman, carrier of β-thal, and in her fetus at prenatal diagnosis (PND) for hemoglobinopathies. The present study emphasizes the importance of sharing the observed changes in the globin gene cluster, especially in the case of new or rare undefined mutations, in order to facilitate the determination of their phenotypic expression and possible interactions with known molecular defects.
