Recall of emotional and neutral words and paragraphs in traumatic brain injury

Background: Traumatic brain injury (TBI) results in verbal recall deficits and impaired processing of emotion encoded in facial appearance, prosody and the linguistic content of messages. Emotion facilitates memory (emotional memory advantage) for non-brain injured (NBI) individuals but the impact of emotion on verbal recall for linguistically encoded stimuli in TBI has not been explored.

Aims: The purpose of this study was to determine the effects of stimulus emotional content on verbal recall of words and paragraphs in TBI compared to NBI individuals.

Methods and procedures: Six 10-item lists, each with five emotional and five neutral words, and six paragraphs (three emotional, three neutral) were counterbalanced and presented in random order to 20 individuals with TBI and 44 NBI. The number of words from lists and the number of content units from paragraphs were compared for the two groups.

Outcomes and results: The NBI participants recalled more words from the lists and content units from the paragraphs than the individuals with TBI. Both groups recalled significantly more emotional than neutral words. NBI but not TBI participants had significantly greater recall for information in paragraphs with emotional content.

Conclusions: Participants with TBI showed impaired recall of words and paragraph content. Emotion facilitated word and paragraph content recall for neurotypical individuals but emotional memory advantage was limited to words for the TBI participants.     

脑卒中患者急性应激障碍及影响因素研究

目的探讨脑卒中患者急性应激障碍发生现状及影响因素。方法采用斯坦福急性应激反应问卷对349例脑卒中住院患者进行调查。结果共163例(46.70%)患者发生急性应激障碍;Logistic回归分析结果显示,患者性格、是否存在偏瘫及是否吞咽功能障碍是脑卒中患者发生急性应激障碍的主要影响因素(P0.05,P0.01)。结论脑卒中患者急性应激障碍发生率较高,内向性格及存在偏瘫和吞咽功能障碍的患者更容易发生急性应激障碍。医护人员应及时为高危患者提供个体化治疗及预见性护理,防止脑卒中患者发生急性应激障碍。     

同轴微切口与传统小切口超声乳化术的临床疗效及术后并发症对比分析

目的　比较1.8 mm同轴微切口超声乳化术与传统同轴3.0 mm小切口超声乳化术的临床疗效及术后并发症。方法　收集2015年5月至10月北京同仁医院北京同仁眼科中心收治的老年性白内障患者48例（48眼），将患者分为微切口组和小切口组。微切口组主切口长1.8 mm，前房内注入透明质酸钠，行直径约为5.0 mm的中央连续环形撕囊，水分离后用劈核钩劈核，扭动模式超声乳化吸出术，自动灌注系统吸出残留皮质。小切口组角膜主切口大小为3.0 mm，术中植入常规折叠式人工晶状体。术后行裂隙灯、眼底镜以及角膜地形图检查，电脑验光检查患者最佳矫正视力。结果　术后1周、1个月、3个月两组患者最佳矫正视力比较，差异均无统计学意义（均为P>0.05）。术后1个月和3个月两组间手术源性散光比较，微切口组均明显低于小切口组，差异均有统计学意义（均为P<0.01）。在微切口组组内术后1个月和3个月手术源性散光无明显差异（P>0.05），微切口组手术源性散光在术后1个月保持稳定。在小切口组组内术后3个月手术源性散光明显低于术后1个月 （P<0.01）。微切口组术前角膜厚度为（567±27）μm，小切口组为（564±25）μm，两组差异无统计学意义（P>0.05）；术后1个月与3个月两组间角膜厚度变化差异亦均无统计学意义（均为P>0.05）。在随访期间两组患者均未发生后发性白内障。结论　1.8 mm同轴微切口白内障超声乳化吸出术安全可靠，术后散光恢复快，可有效减少术后角膜手术源性散光。     

疼痛管理在创伤骨科护理管理中的应用价值

目的探究创伤骨科护理管理中疼痛管理的应用价值。方法 82例患者选取于2017年6月-2018年6月,所有患者均来源于本院骨科收治的住院患者,数字表为患者分组原则,常规组41例,疼痛组41例,分别予以常规护理、常规护理+疼痛管理,比较满意度、疼痛评分及平均住院时间。结果疼痛组满意度92.68%比常规组73.17%高,差异具有统计学意义(χ^2=5.513,P <0.05),患者干预后的疼痛评分低于常规组,平均住院时间短于常规组,差异存在统计学意义(P<0.05)。结论疼痛管理用于创伤骨科护理管理中,患者疼痛明显减轻,患者满意度高,缩短了患者的平均住院时间。     

Cataract Surgery in HIV Seropositive Patients: Long-Term Follow-Up

Purpose: To study epidemiology and clinical findings of cataract in HIV+ patients.

Methods: A total of 32 HIV+ patients, 11 with uveitis/retinitis before surgery and 21 without, mean follow-up 44.9 ± 36.6 months, and 114 HIV- patients, 57 with uveitis/retinitis before surgery and 57 without, were retrospectively compared.

Results: Visual acuity improved in all HIV+ patients (p < 0.001), who were younger (p = 0.01) and more frequently males (p = 0.027). HIV+ patients with uveitis prior surgery improved less (p = 0.046) than HIV- (p < 0.001); their anterior chamber inflammation was similar to baseline. Male sex (p = 0.005), younger age (p < 0.001), dyslipidaemia (p = 0.058), HBV+ (p = 0.037), and unilateral cataract (p = 0.001) were more frequent in HIV+ patients with senile cataract, but they showed the same postoperative course as HIV- patients.

Conclusion: Cataract surgery in HIV+ patients is safe and effective. Uveitis prior to surgery did not significantly affect the postoperative course. Systemic comorbidities are more frequent in HIV+ patients with senile cataract than in HIV- subjects.     

白内障围手术期结膜囊菌群分布及药敏试验

目的 分析白内障围手术期结膜囊菌群的分布及药敏试验结果。方法 选取264例白内障患者,分别在患者入院后、手术消毒前、手术消毒后、手术结束后四个时间点取样,进行细菌培养及药敏试验,比较不同时期的细菌培养结果和药敏结果。结果 入院后结膜囊细菌培养阳性率明显高于手术消毒前、手术消毒后及手术结束后;入院后结膜囊细菌培养以表皮葡萄球菌为主;革兰氏阳性球菌对头孢西丁、加替沙星、左氧氟沙星等敏感性较高。结论 表皮葡萄球菌是结膜囊最常见的细菌,术前应常规应用抗生素点眼,聚维酮碘冲洗结膜囊等来预防术后感染性眼内炎。
