Risk factors and outcomes of cardiovascular disease readmission within the first year after dialysis in peritoneal dialysis patients

BackgroundIn the first year of dialysis, patients are vulnerable to cardiovascular disease (CVD) hospitalization, but knowledge regarding the risk factors and long-term outcomes of cardiovascular readmission within the first year after dialysis in incident continuous ambulatory peritoneal dialysis (CAPD) patients is limited.MethodsThis retrospective cohort study was conducted in incident CAPD patients. The demographic characteristics, laboratory parameters, and CVD readmission were collected and analyzed. The primary outcome was all-cause mortality, and the secondary outcomes included CVD mortality, infection-related mortality and technique failure. A logistic regression was used to identify the risk factors associated with CVD readmission within the first year after dialysis. Cox proportional hazards models were used to evaluate the association between CVD readmission and the outcomes.ResultsIn total, 1589 peritoneal dialysis (PD) patients were included in this study, of whom 120 (7.6%) patients had at least one episode of CVD readmission within the first year after dialysis initiation. Advanced age, CVD history, and a lower level of serum albumin were independently associated with CVD readmission. CVD readmission within the first year after dialysis was significantly associated with all-cause (HR 2.66, 95%CI 1.91–3.70, p < 0.001) and CVD (HR 3.42, 95%CI 2.20–5.31, p < 0.001) mortality, but not infection-related mortality or technique failure, after adjusting for confounders.ConclusionsOur findings suggest that an advanced age, a history of CVD, and a lower level of serum albumin were independently associated with CVD readmission. Moreover, CVD readmission was associated with all-cause and cardiovascular mortality in incident CAPD patients.     

张海峰基于体用学说治疗慢性非特异性腰痛经验介绍

慢性非特异性腰痛是康复科门诊常见疾病之一,由于其具体病理机制还未完全阐明,目前临床治疗多以对症治疗为主。张海峰主任结合自身临证经验,根据非特异性腰痛的疾病特点,认为其多是以人体体用关系失和所致。人体以一元之气为“体”,脏腑经络的外在功能为“用”。脾肾亏虚,运化失职,气化失常,气血不充,一元之气虚衰,不荣则痛,发为腰痛;气虚血瘀,阻滞经络,又或再受邪气侵犯,寒湿阻滞,不通则痛,而成本虚标实之证。张主任据此提出通补元气、化瘀止痛的治疗法则,并且结合中西医及康复物理治疗等方法,疗效甚佳。

慢性肺源性心脏病人血液触变特性

本文用Low Shear 30流变测定仪,测定了55例肺心病患者全血触变特性的变化,分析了这些变化与肺心病发生和发展的关系。结果表明:肺心病患者血液的触变特性发生了异常改变。HCT、τ_o、η_s、μ、(η_s-μ)、A、ARC均升高,并随病情加重而逐渐明显。其原因主要在于肺心病缺氧所致的继发性红细胞增多及血液氧分压降低,和二氧化碳分压升高所致的红细胞变形性降低。血液触交特性的改变又使血液循环外周阻力增大,右心负荷增加,从而进一步加重了病情的发展。     

刺五加对豚鼠地高辛中毒的影响

豚鼠灌服地高辛复制地高辛中毒模型，研究五加对地高辛中毒的影响。结果发现，服刺五加组豚鼠发生心律失常较未给药组明显推迟，而血中地高辛浓度则显著高于未给药组，提未临床应用地高辛时同时给予刺五加有于减少减轻地高辛的毒性反应。     

Studies an morphological typing of argyrophilic nucleolar organizer regions

Morphological typing of argyrophilic nucleolar organizer regions (AgNOR) in 300 caws of malignant tumors and 140 cams of benign lesions was analyzed and five morphological types of ApNOR were described in detail. In malignant tumors, the diffuse type (78%) was the most frequently seen, and in benign lesions, the nucleolar type (92.85%); the difference was thus highly significant (P < 0.001). The intranucleolar and aggregate types were not observed in benign lesions. There was no obvious difference in the proportion of the mixed type in benign and malignant lesions (P > 0.05). The relationship between grade of malignancy and morphological typing of AgNOR and its clinical significance are discussed.     

小脑和脑干梗塞致突发性耳聋

目的:了解小脑和脑干梗塞引起的突发性耳聋的临床特点.探讨其发病机制.方法:回顾性分析12例小脑和脑干梗塞所致突发性耳聋的临床资料.结果:该组患者主要临床表现为耳聋、眩晕、耳鸣、眼震、同侧颜面麻木感.头颅CT或MRI发现小脑或脑干有小于2 cm的梗塞灶.结论:发病机制主要为小脑前下动脉(AlCA)供血不足使小脑脑桥角或脑干缺血,损伤该区域的耳蜗神经和听神经传导通路,导致耳聋.小脑和脑干梗塞的诊断主要依据临床表现、CT或MRI检查.     

三味中药配伍应用对改善烫伤小鼠受损免疫功能的作用

目的　观察对烫伤小鼠受损免疫功能具有调理作用的单味中草药 ,经过配伍应用后的协同作用。方法　采用 1 .0 3 4× 1 0 5 Pa的蒸气烫伤 1 0s ,烫伤面积 1 6% ,深度为Ⅲ度的致伤模型烫伤动物。通过观察MΦ的吞噬功能、枯否细胞清除能力、MΦ抗原提呈功能、血清TNF量、淋巴细胞增殖反应及IL 2产生能力、小鼠抗体产生能力、PMNH2 O2 释放量及PMN溶菌酶释放量、血清补体的趋化作用和聚集作用等指标 ,籍以了解单味中药与配伍中药对烧 (烫 )伤小鼠受损免疫功能的调理作用。结果　单味中药三七(PP) ,金银花 (LJ)和虎杖 (PC)对小鼠受损免疫功能有一定的改善作用。PC +LJ、PP +PC、PP +LJ等二味配伍的中药 ,除少数指标外 ,均比单味药的作用好。而PP +LJ+PC三味配伍药的调理作用 ,比单味药和二味配伍药的调理作用更佳。结论　单味中药经配伍应用后对烧 (烫 )伤小鼠严重受损的免疫系统功能 ,具有比单味药更好的协同调理作用。
