辛伐他汀治疗无症状性颈动脉粥样硬化的疗效观察

目的采用颈动脉超声观察辛伐他汀治疗无症状性颈动脉粥样硬化的疗效。方法对参加我院健康体检时经彩超检查发现有颈动脉斑块的观察病例68例，每晚服用辛伐他汀，连续4月，观察颈动脉斑块的面积变化以及血脂的动态改变。结果68例观察者共发现斑块112个，服药4月后发现低回声斑块面积消退幅度达32％，混合性斑块达25％，高回声斑块只有9％，平均消退幅度22％，除高回声斑块外，其他均有明显统计学意义（P〈0．05）。患者的TC下降与治疗前比较有显著差异（P〈0．01），TG、LDL的下降与治疗前比较有明显差异（P〈0．05），HDL有所升高，但无统计学意义。结论通过观察服用辛伐他汀4月后斑块的面积变化以及血脂的改变结果表明，坚持服用他汀类药物，可以达到稳定与消退斑块的作用。     

Treatment of Intervertebral Disc Degeneration

Intervertebral disc degeneration (IDD) causes a variety of signs and symptoms, such as low back pain (LBP), intervertebral disc herniation, and spinal stenosis, which contribute to high social and economic costs. IDD results from many factors, including genetic factors, aging, mechanical injury, malnutrition, and so on. The pathological changes of IDD are mainly composed of the senescence and apoptosis of nucleus pulposus cells (NPCs), the progressive degeneration of extracellular matrix (ECM), the fibrosis of annulus fibrosus (AF), and the inflammatory response. At present, IDD can be treated by conservative treatment and surgical treatment based on patients'' symptoms. However, all of these can only release the pain but cannot reverse IDD and reconstruct the mechanical function of the spine. The latest research is moving towards the field of biotherapy. Mesenchymal stem cells (MSCs) are regard as the potential therapy of IDD because of their ability to self‐renew and differentiate into a variety of tissues. Moreover, the non‐coding RNAs (ncRNAs) are found to regulate many vital processes in IDD. There have been many successes in the in vitro and animal studies of using biotherapy to treat IDD, but how to transform the experimental data to real therapy which can apply to humans is still a challenge. This article mainly reviews the treatment strategies and research progress of IDD and indicates that there are many problems that need to be solved if the new biotherapy is to be applied to clinical treatment of IDD. This will provide reference and guidance for clinical treatment and research direction of IDD.     

A Damage Model of Concrete including Hysteretic Effect under Cyclic Loading

A novel damage model for concrete has been developed, which can reflect the complex hysteresis phenomena of concrete under cyclic loading, as well as other nonlinear behaviors such as stress softening, stiffness degradation, and irreversible deformation. The model cleverly transforms the complex multiaxial stress state into a uniaxial state by equivalent strain, with few computational parameters and simple mathematical expression. The uniaxial tensile and compressive stress–strain curves matching the actual characteristics are used to accommodate the high asymmetry of concrete in tension and compression, respectively. Meanwhile, an unloading path and a reloading path that can reflect the hysteresis effect under cyclic loading of concrete are established, in which the adopted expressions for the loading and unloading characteristic points do not depend on the shape of the curve. The proposed model has a concise form that can be easily implemented and also shows strong generality and flexibility. Finally, the reliability and correctness of the model are verified by comparing the numerical results with the three-point bending beam test, cyclic loading test, and a seismic damage simulation of the Koyna gravity dam.     

家庭干预在精神分裂症患者社会功能障碍康复中的效果分析

目的分析精神分裂症患者社会功能障碍的现状并探讨家庭干预对其康复效果的影响。方法分析我院门诊收治的128例精神分裂症患者入院治疗前的社会功能状况;患者出院后,将患者随机分为家庭干预组和对照组各64例;对照组给予常规精神病药物维持治疗,干预组在此基础上给予家庭干预治疗1年,并采用社会功能缺陷量表（SDSS）及康复状态量表（MRSS）评估患者的治疗效果;并观察患者的服药依从性及病情复发情况。结果 120（93.7%）例的患者存在明显的社会功能障碍,集中表现在职业及工作、计划性及责任心、对外界的关心及兴趣方面;家庭干预前两组间SDSS、MRSS评分并无显著差异（P〉0.05）,干预后干预组此两项得分均低于对照组（P〈0.05）;同时干预组的服药依从性、复发率情况均优于对照组（P〈0.05）。结论精神分裂症患者大都存在较为严重的社会功能障碍,家庭干预可以显著提高患者生活质量,改善社会功能,降低复发率。
