肺表面活性物质联合鼻塞式持续气道正压通气治疗新生儿呼吸窘迫综合征的护理

目的探讨肺表面活性物质(固尔苏)联合鼻塞式持续气道正压通气(NCPAP)对新生儿呼吸窘迫综合征(NRDS)的疗效及其相关护理策略。方法选取本院2012年1月至2013年12月收治的58例NRDS患儿并随机分为两组各29例,对照组行机械通气+固尔苏治疗,观察组行NCPAP+固尔苏治疗,两组患儿治疗期间均给予新生儿儿科常规性护理,观察两组患儿的病情转归及预后情况。结果观察组患儿抢救成功率为89.66%、死亡率为10.34%,对照组分别为75.86%、24.14%,两组比较P<0.05。观察组患儿机械通气时间、住院时间、家属满意度评分显著优于对照组(P<0.05)。结论固尔苏与NCPAP治疗NRDS效果显著,在治疗期间给予患儿科学、全面的护理可提高患儿预后,缩短患儿住院时间,提高患儿家属满意度。     

两种磁共振血管成像序列对脑静脉畸形的比较影像学研究

目的探讨磁共振静脉血氧水平依赖成像（VEN-BOLD）和时间飞跃法血管成像（TOF-MRA）对静脉畸形（CVM）的诊断价值。方法采用1.5T超导磁共振扫描仪对我院收治的13例CVM患者进行TOF-MRA和VEN-BOLD对比成像分析。结果 TOF-MRA原始轴位图像可显示全部13例CVM的引流静脉,并可进行最大密度投影重建（MIP）3D图像观察,但仅6例原始图像可显示稀少的髓静脉;而VEN-BOLD可清晰显示全部13例CVM的引流静脉及更多的髓静脉。结论 TOF-MRA可对CVM的引流静脉进行3D直观显示;而VEN-BOLD可清晰准确地显示CVM的引流静脉及髓静脉,二者结合可作为CVM诊断必要的补充序列。     

超低出生体重儿呼吸支持策略及进展

呼吸支持与超低出生体重儿（extremely low birth weight infant， ELBWI）的生存率有关。由于肺保护通气策略的广泛应用，使ELBWI呼吸衰竭死亡率显著下降；随着肺表面活性物质（PS）时代的到来，常规的机械通气呼吸支持手段显得不如20世纪80年代那么重要，但通气模式对于这些非常微小的ELBWI的治疗成功率关系仍然非常密切。新的呼吸模式如无创机械通气、患者触发呼吸模式（PTV）、高频通气（high-frequency ventilation，HFV）、神经调节的呼吸支持等技术的出现，为ELBWI的呼吸救治提供了新的机会。

目的：探讨彩超对锁骨下动脉综合征（SSS）的检查技巧及临床诊断价值。方法选取我院2010年8月-2013年6月间确诊为锁骨下动脉盗血综合征患者53例，进行颈动脉、椎动脉及锁骨下动脉二维超声及彩色多普勒超声检查，分析血流动力学特点。结果53例患者中动脉粥样硬化38例，多发性大动脉炎15例。根据椎动脉频谱特点划分为隐匿型SSS共17例，患侧椎动脉频谱收缩期出现切迹；部分型SSS共26例，患侧椎动脉收缩期血流反向；完全型SSS共10例，患侧椎动脉血流收缩及舒张期均反向。结论彩超对于早期筛查SSS具有明显优势，并可对大多数SSS进行病因学诊断。     

Evaluation of Adiponectin, Resistin, IL-6, TNF-a in Obese and Non-obese Women with Polycystic Ovary Syndrome

Objective To evaluate possible clinical effects of adiponectin, resistin, IL-6, and TNF-α in obese and non-obese patients with polycystic ovary syndrome (PCOS). Methods Seventy selected PCOS patients were recruited for this study, and were divided into two groups based on their body mass index (BMI): 35 obese (BMI ≥ 25kg/m2 , group A), 35 non-obese (BMI<25kg/m2 , group B). In addition, 35 healthy non-obese women (BMI<25kg/m2 ) were enrolled as the control (group C). Serum levels of FSH, LH, T, glucose, insulin, adiponectin, resistin, IL-6, TNF-α were detected, and compared the differences of them among three groups. Results Blood glucose levels among three groups had no difference (P>0.05). Blood insulin level was significantly greater in group A than in group B or group C (P<0.05), and a significant difference existed between group B and group C (P<0.05). The ratio of glucose/insulin was significantly higher in group A than in group B or group C (P<0.05), and the ratio in group B was significantly higher than that in group C (P<0.05). Adiponectin level was significantly lower and resistin level was significantly higher in group A than in group B or group C (P<0.05). IL-6 level in group C was significantly lower than that in group A or group B (P<0.05), and significant difference was found between group A and group B (P<0.05). TNF-α level was a slight high in group B, whereas there was no statistical difference among three groups (P>0.05). Conclusion Disturbances of some metabolic and inflammatory adipokines could involve the pathogenesis of PCOS in both obese and non-obese women. Low-grade chronic inflammation might have negative effects on the development of PCOS in non-obese women.

目的观察走动式管理应用于小儿急诊分诊护理质量管理后的实际效果。方法将采用了走动式管理模式下的护理方法所护理的小儿急诊患者,设置为试验组;对照组则为仅接受常规护理的同等例数小儿急诊患者,对比两组患儿的临床护理质量,并比较两组患方的满意度。结果走动式管理组患者的护理质量评分和满意度均优于对照组患者。结论走动式管理模式下的护理方式,能够更方便、快捷地缓解小儿病患的临床症状,更大程度上减轻家属的紧张情绪,较常规护理措施质量更佳,具有较高的应用和推广价值。     

慢性淋巴细胞性白血病患者miR-9-3甲基化异常及其意义

目的本研究旨在探讨microRNA-9-3(miR-9-3)在慢性淋巴细胞性白血病骨髓细胞中的甲基化异常及其意义。方法采用甲基化特异性聚合酶链反应(MSP)技术检测8例正常骨髓组织、78例新确诊的慢性淋巴细胞性白血病患者和7种白血病细胞株甲基化水平。结果正常对照组miR-9-3呈未甲基化状态;7种白血病细胞株中有5种呈未甲基化状态(71.4%);78例慢性淋巴细胞性白血病患者中65例呈miR-9-3甲基化,MSP阳性率为83%。5-氮杂-2'-脱氧胞苷(5-Aza Dc)处理白血病细胞株后I83-E95和WAC3CD5+细胞株miR-9-3呈未甲基化状态。结论慢性淋巴细胞性白血病患者存在miR-9-3表达受抑,可能与其基因甲基化异常有关。而miR-9-3甲基化在激活慢性淋巴细胞性白血病患者NF-κB1信号通路的作用值得进一步研究。     

Evaluation on Antisperm Antibody in Infertile Women with Chronic Salpingitis

Objective To evaluate the level of antisperm antibody （ASA） in infertile women with chronic salpingtis. Methods Forty-eight infertile women with chronic salpingtis were enrolled into this study. Serum samples were screened by the direct immunobead test for ASA type IgG and IgA according to the WHO laboratory manual. About 50% or more of the motile sperm attaching to one or more immunobeads were regarded as clinical positivity according to the WHO criteria. About 20% 50% motile sperm that had adherent particles were deemed to be sub-positive. Results Of the 48 patients with chronic salpingtis assessed for ASA-IgG, 4 had immunobead bindings ranged from 50% to 60%, and the positive rate was 8.3%. In addition, 5 cases had 20%-40% of immunobead bindings, and the sub-positive rate was 10.4%. For ASA-IgA detecting, 2 cases with ASA-IgG positivity also had ASA-IgA immunobead bindings, and the positive rates were 22%, and 28%, respectively. Conclusion The incidence of ASA could be found in infertile women with chronic salpingtis, which suggests that an increased risk for the production of ASA would exist in the inflammatory status o f fallopian tube.
