脑梗塞患者血清肺炎衣原体特异性抗体的检测

目的探讨肺炎衣原体(CPn)感染与动脉血栓性脑梗塞的关系.方法用酶联免疫吸附试验(ELISA)法测定了112例脑梗塞患者和50例其他疾病患者的血清肺炎衣原体特异性IgG抗体及IgM抗体.结果肺炎衣原体慢性感染率分别为脑梗塞组的85.71%(96/112)和对照组48.00%(24/50),脑梗塞患者肺炎衣原体慢性感染率均明显高于对照组,肺炎衣原体IgG阳性病例血清TG浓度明显高于肺炎衣原体IgG阴性的病例(P＜0.05);HDL-C则明显低于阴性组.结论脑梗塞患者肺炎衣原体感染率明显增高,提示肺炎衣原体感染可能与脑梗塞有关.其可能的机制是肺炎衣原体感染后形成免疫复合物沉积在血管壁,引起血管局部损伤;并改变了血脂浓度,增加了脑血管病发生的危险性.     

Factors associated with successful rehabilitation in older adults: A systematic review and best evidence synthesis

Purpose; Returning to community living is an indicator for successful rehabilitation in older adults admitted to geriatric rehabilitation. Predicting successful rehabilitation could contribute to the deployment of early discharge planning, and leads to a more custom-made rehabilitation trajectory. This review aims to present an overview of factors associated with successful rehabilitation following inpatient geriatric rehabilitation.Method; A systematic literature review was conducted in PubMed, CINAHL and Embase. Extracted factors were analysed via Bakker's five levels of evidence.Results; Nine studies with methodological quality of good to moderate were included. For 13 of the 18 extracted factors, limited (n=3), moderate (n=5) and conflicting (n=5) evidence found a significant association.Conclusions; Caregiver, comorbidities, motor-function, nutritional status, time from onset are significantly related to successful rehabilitation. These factors could support healthcare professionals to indicate successful rehabilitation at admission and contributes to deployment of early discharge planning and development of more custom-made rehabilitation trajectories.     

The effect of resistance training on sleep in Chinese older adults: A randomized controlled trial

Sleep disturbances affect approximately half of the older adult population and add additional risks of developing Alzheimer's disease. This study is to test the effects of a 12-week resistance training (RT) program on sleep in older adults residing in an assisted living facility in China. A total of 62 eligible participants were randomly assigned to RT (n = 31) or control group (n = 31). Participants in RT group participated in three 1-hour moderate intensity RT sessions per week for 12 weeks (at least 48 h between sessions). In the overall sample, sleep efficiency increased (P < 0.01), wake after sleep onset (P < 0.01) decreased in participants in RT group at post-intervention, compared to control group. Similar results were found in participants with mild cognitive impairment (MCI). The findings support that RT improves sleep efficiency and decreases sleep fragmentation in older adults in general and in those with MCI.

目的了解急性脑出血后全身炎症反应综合征(SIRS)的发生率及其发生可能有关的因素,探讨SIRS在判断急性脑出血的病情和预后方面的临床价值.方法回顾性分析163例急性脑出血病人的临床资料,且以目前外科、危重病领域公认的SIRS、多器官功能障碍综合征(MODS)的诊断标准为依据,了解急性脑出血后SIRS和MODS的发生情况及相关问题.结果急性脑出血后SIRS的发生率为52%;出血量≤30 mL、出血破入脑室、随机血糖≥11.1 mmol/L的病人,SIRS的发生率分别较出血量＜30 mL、出血未破入脑室、随机血糖＜11.1 mmol/L的病人显著增高.脑出血后发生SIRS的病人,其MODS发生率、病死率均明显高于未发生SIRS的病人.结论急性脑出血后SIRS的发生率高,SIRS的发生提示病情危重,预后较差.     

Coping and adaptation to dementia family caregiving: A pilot study

Family caregivers of Black older adults with dementia are at risk for cognitive decline and premature death. Reducing this risk and filling the void of culturally responsive interventions for caregivers requires the development of participant informed models of care that promote group strengths such as effective coping. In this pilot study, Black family caregivers (n=30) completed a survey comprised of a demographic questionnaire, various measures of function, self-efficacy, social support, and coping. Study findings point to a well-educated population with underlying health concerns such as obesity, hypertension, and diabetes that may be complicated by caregiving stress. Common coping strategies used by participants included spiritual coping (80%), use of past experiences (80%), and information gathering (75%). Clinicians can support dementia family caregivers by promoting spiritual coping and self-care, as well as providing reference resources about respite and managing challenging behaviors. Power analysis suggests a future sample size of 385.     

重组人生长激素对兔角膜损伤早期修复的研究

目的：探讨重组人生长激素(rHGH)对兔角膜上皮损伤早期的修复作用。

方法：选取32只健康雄性新西兰兔制作双眼角膜上皮损伤模型,随机选取1眼滴无菌生理盐水作为对照组,另1眼滴20nmol/L重组人生长激素作为rHGH组,分别于造模前、造模后24、48、72h采用荧光素钠染色法观察角膜上皮愈合情况,采用Cochet-Bonnet角膜知觉测量仪测量检查中央角膜敏感度,同时收集各时间点泪液检测炎症因子的表达。

结果：造模后48h对照组和rHGH组角膜上皮愈合率分别为62.52%±6.73%和79.62%±10.62%(P<0.05),造模后72h分别为90.56%±9.57%和98.43%±3.65%(P<0.05)。造模后48h,对照组和rHGH组中央角膜敏感度分别为3.22±0.42、4.22±0.26cm(P<0.05)。造模后各时间点两组泪液TNF-α和IL-1α表达均较造模前增加,且对照组均高于rHGH组。造模后24、48h,两组泪液MMP-9表达均较造模前增加,且造模后48h对照组高于rHGH组(均P<0.05)。造模后24、48h两组泪液IL-21表达均较造模前增加(P<0.05)。造模后各时间点两组泪液IL-17α、Leptin表达与造模前相比及两组之间比较均无差异(P>0.05)。

结论：重组人生长激素有利于兔角膜上皮损伤早期修复。     

白细胞抗原G在结肠癌中的表达及意义

【摘要】 目的 研究结肠癌切除标本中远癌组织、癌旁组织及癌组织白细胞抗原G(HLA-G)蛋白表达情况,探讨HLA-G在结肠癌发生、发展中的作用。方法 应用免疫组化SP法,检测HLA-G 蛋白在结肠癌远癌组织、癌旁组织及癌组织的表达情况。结果 癌组织与癌旁组织、远癌组织比较具有统计学意义(P<0.01),癌旁组织与远癌组织比较具有统计学意义(P<0.01)。 HLA-G 与结肠癌血管侵犯、淋巴结转移及临床病理分期有关(P<0.01),而与性别、年龄、肿块大小、肿块部位、癌胚抗原(CEA)水平及组织学分级无关。结论 HLA-G 在结肠癌中高表达。HLA-G 在血管侵犯组、淋巴结转移组及临床分期较晚组表达显著升高,这些因素可能与结肠癌的侵袭和转移有关。
