Liguzinediol对阿霉素诱导的慢性心衰大鼠心功能的影响

目的 通过阿霉素（Dox）复制大鼠慢性心力衰竭（CHF）模型，观察Liguzinediol对CHF大鼠心功能的影响。方法 通过血流动力学观察Liguzinediol对Dox（腹腔注射，2 mg/kg）诱导的CHF大鼠左心室内压最大上升/下降速率(±dp/dt_max)、左心室内压(LVSP)、动脉收缩压(ASP)、动脉舒张压(ADP)和心率(HR)的变化；观察Liguzinediol对血清一氧化氮（NO）、一氧化氮合成酶（NOS）、超氧化物歧化酶（SOD）、肿瘤坏死因子-α（TNF-α）和白细胞介素-6（IL-6）以及血浆中丙二醛（MDA）的影响。结果 Liguzinediol能增加LVSP、+dp/dt_max、ASP、ADP、AP、HR，降低-dp/dt_max(P<0.05~0.01)；降低NO、iNOS以及MDA的浓度，同时增强了SOD的活性(P<0.05~0.01)；抑制IL-6和TNF-α的生成(P<0.05~0.01)。结论 Liguzinediol可明显改善Dox诱导的CHF大鼠血流动力学指标，减少模型大鼠炎症因子的释放以及抑制氧自由基的生成。

Effectiveness of virtual reality in the treatment of hand function in children with cerebral palsy: A systematic review

Study DesignSystematic review.IntroductionChildren with cerebral palsy (CP) may have limited use of their hands for functional activities and for fine motor skills. Virtual reality (VR) is a relatively new and innovative approach to facilitate hand function in children with CP.Purpose of the StudyThe primary purpose of this study was to determine the effectiveness of VR as an intervention to improve hand function in children with CP compared to either conventional physiotherapy or other therapeutic interventions. The secondary purpose was to classify the outcomes evaluated according to the International Classification of Functioning, Disability and Health (ICF) dimensions.MethodsA International prospective register of systematic reviews (PROSPERO)-registered literature search was carried out in August 2015 in MEDLINE, CINAHL, ERIC, HealthSTAR, AMED, BNI, Embase, PsycINFO, PEDro, Cochrane Central Register, DARE, OTSeeker, REHABDATA, HaPI, CIRRIE, and Scopus. PRISMA guidelines were followed. Only randomized controlled trials (RCTs) were included, and their methodological qualities were examined using the Cochrane collaboration's risk of bias (RoB) tool. A narrative synthesis was performed.ResultsThe 6 RCTs published on this topic provide conflicting results. Four studies reported improved hand function (2 low RoB, 1 high RoB, and 1 unclear RoB), whereas 2 studies reported no improvement. All of the RCTs reported the activity element of ICF, but no study explicitly described the effect of VR intervention based on the ICF model.ConclusionThe role of VR ti imrpove hand fucntion in children with CP is unclear due to limited evidence; use as an adjunct has some support.     

Peritoneal dialysis improves lung function in rats with lung injury induced by shock wave

Objective To prove the efficacy of peritoneal dialysis on shock wave-induced acute lung injury of rats, and analyze its mechanisms. Methods Forty-five adult Sprague-Dawley rats were randomly divided into three groups: control group, sham operation (Sham) group and peritoneal dialysis (PD) group. Sham group and PD group did abdominal catheterization before blast injury. The 55 kg shock wave (bst-I) was used to induce lung blast injury. After one hour of blast injury, PD group was given 2.5% peritoneal dialysate 20 ml to stay abdomen, which was released 30 min posted, repeated 12 cycles. After 6 hours of peritoneal dialysis, all of the rats were sacrificed. Partial damaged tissues in lung were used to evaluate the pathomorphologic changes by HE staining, and the remnants were used to measure the lung water content. Lung function was detected by blood gas analyzer and small animal detector from the arterial blood gas. The levels of serum inflammatory factors, such as tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6 and monocyte chemoattractant protein-1 (MCP-1) were tested by ELISA. Results The relative integrity of alveolar structure, interstitial edema and inflammatory cell infiltration in PD group were significantly improved than those in control group. The lung water content of PD group was significantly lower than that of control group (P＜0.05). The levels of TNF-α, IL-1β, IL-6 and MCP-1 in serum of PD group were significantly lower than those in control group (all P＜0.05). The blood oxygen saturation, oxygen partial pressure, oxygenation index, vital capacity, functional residual volume and maximum mid-expiratory flow rate in PD group were significantly higher than those in control group (all P＜0.05). Conclusions Through reducing pulmonary edema and inflammatory factors, peritoneal dialysis can improve lung function in shock wave -induced acute lung injury of rats.     

The impact of stenosis and translation on spinal cord injuries in traumatic cervical facet dislocations

BACKGROUND CONTEXT

Although facet dislocations account for only 6% of cervical trauma, the consequences are often devastating. Cervical facet dislocations are associated with a disproportionate amount of spinal cord injuries; however, neurologic examination of patients is often difficult, as patients commonly present with reduced levels of consciousness. There are limited studies that have investigated the impact of spinal canal diameter and translation on neurologic injury following facet dislocations.
