Total-and lipid-associated sialic acid in serum and thrombocytes in patients with chronic heart failure

ObjectivesTo investigate and discuss the total-, lipid-associated, and thrombocyte-sialic acid levels in chronic heart failure (CHF) patients.Design and methodsThirty-one chronic heart failure patients and 38 healthy controls were included in the study. Serum total sialic acid (TSA), lipid associated sialic acid (LASA), thrombocyte sialic acid (TrSA) were determined together with the traditional inflammation and prognostic markers.ResultsSerum TSA levels were significantly higher in patient group (3.08 ± 0.33 mmol/L) than control group (2.60 ± 0.17 mmol/L). Serum LASA, homocysteine, high-sensitivity CRP, brain natriuretic peptide and erythrocyte sedimentation rate were also significantly higher in patient group. TrSA levels were not significant between the groups.ConclusionTSA and LASA levels increase in CHF, independent from coronary artery disease. TrSA levels were not found to be a prognostic or valuable marker for CHF patients. Acute phase response and lipid associated portions of SA are thought to be responsible for SA rise in CHF.     

舌侧自锁托槽矫治技术的研究进展

舌侧自锁托槽矫治技术是将自锁托槽应用于舌侧正畸的一种全新的矫治方法.该技术兼容了自锁托槽和舌侧矫治2项技术,既拥有自锁托槽固有的低摩擦力、短矫治疗程和节省门诊椅旁操作时间等优势又同时具备舌侧矫治"隐形矫正"的美观性.因此,舌侧自锁托槽矫治技术具有其他矫治技术所不具备的优点,其先进性不言而喻,必定会在将来的正畸界占有一席之地.本文就舌侧自锁托槽矫治技术的研究进展作一综述.     

腹腔镜胆囊切除术并胆管损伤的诊断治疗

目的 探讨腹腔镜胆囊切除术(laparoscopic cholecystectomy,LC)胆管损伤的原因、诊断和治疗.方法 回顾性分析近7年来行腹腔镜胆囊切除术1656例患者的临床资料.结果 胆囊息肉274例,胆囊结石伴急性胆囊炎168例,胆囊结石伴慢性胆囊炎1214例.共发生胆管损伤15例(0.91%),术中发现8例,术后早期发现7例.术中诊断主要依据手术野胆汁渗出或发现有2个胆管残端;术后诊断主要依靠临床症状、体征及影像学检查.1例患者行胆管壁缝合修补+T管支撑引流,4例患者行胆管端端吻合术,其中1例行胆管端端吻合加内支架支撑术后发生胆瘘而行再次开腹胆肠Roux-en-Y吻合术,其余10例患者均行胆肠Roux-en-Y吻合术,均痊愈出院,愈后良好.结论 腹腔镜胆囊切除术胆管损伤与病因无关,术中及术后早期发现及恰当的处理,愈合良好.胆肠Roux-en-Y吻合术是胆管损伤最主要的修复术式.     

院外综合管理对支气管肺发育不良极早产儿近期预后的影响

目的 通过与非支气管肺发育不良(BPD)极早产儿进行对比,探讨院外综合管理对BPD极早产儿近期预后的影响。方法 选取2013年1月-2014年10月于中山大学附属第一医院出生并收住新生儿重症监护室(NICU)、存活时间≥28 d的极早产儿为研究对象,按有无合并BPD分为BPD组及非BPD组。对患儿出院后均进行规范随访及早期干预,比较两组患儿体格和神经系统发育情况、呼吸道症状发生率和再住院次数。结果 符合入选标准有76例极早产儿,其中BPD患儿39例,BPD发生率51.3%。两组均无死亡、失明及脑瘫患儿。BPD组纠正3、6月龄及12月龄时体重、身长完成追赶性生长比例与非BPD组相仿(P≥0.05),但头围的追赶性生长较非BPD组差(P<0.05)。BPD组合并肺炎次数、哮喘发作次数、再入院次数明显高于非BPD组(P<0.05)。结论 院外综合管理可改善BPD极早产儿预后,有助于促进其追赶性生长及减少神经系统不良预后,达到非BPD极早产儿水平,但未能降低其呼吸道症状发生率。     

小城镇及农村残疾人抑郁水平及相关因素的调查

目的:了解小城镇及农村残疾人的抑郁水平及其相关因素,为其居家照顾者减轻残疾人抑郁提供理论依据。方法:采用抑郁自评量表(SDS)、Barthel氏ADL指数量表、Procidana与Heller家庭支持量表及自行设计的一般资料问卷,对居住在小城镇及农村的63例残疾人进行问卷调查。结果:残疾人有抑郁症状的比例高达69.8%,残疾人抑郁水平与日常生活活动能力(ADL)及残疾人对其家庭照顾者照顾满意度呈负相关,有非常显著的统计学意义(P=0.000)。结论小城镇及农村残疾人的抑郁症状普遍较严重,社会应给予更多的关注,应大力发展社区护理,为有需要的残疾人上门服务,并加强对残疾人家庭照顾者的培训指导,以提高残疾人生活质量与心理健康水平。     

Vascular air embolism during percutaneous nephrolithotomy without pneumopyelogram: a case report of successful rescue

Vascular air embolism (VAE) is a rare complication of percutaneous nephrolithotomy. Paradoxical air embolization resulting from VAE may be more likely to occur in patients with an atrial-septal defect, such as patent foramen ovale. Here, the case of a female patient with VAE that occurred during percutaneous nephrolithotomy is presented. Although the patient was diagnosed with patent foramen ovale, she recovered well without any severe paradoxical air embolization symptoms. To our knowledge, this is the first report of VAE with paradoxical air embolization that occurred in a patient with patent foramen ovale during percutaneous nephrolithotomy that was conducted without pneumopyelography.     

蒙脱石散治疗口腔溃疡临床观察
