The problem of the way to observe the motor imagery and executing task of motor imagery effectively are emphasized. Finally we provide an addressing on motor imagery questionnaires.

Acetaminophen(APAP)is the most wideIy-used anaIgesic drug cIinicaIIy. It is aIso the most risky agent for hepatotoxicity. It has been wideIy used as a modeI drug to study mechanisms of chemicaI-induced Iiver injury and to test the hepatoprotective potentiaI of chemicaIs. This review summa-rized the intraceIIuIar events of acetaminophen-induced hepatotoxicity,incIuding metaboIic activation, ceIIuIar damage,c-Hun N-terminaI kinase pathway,and modified metaboIism function,and additionaIIy focused on the roIe of infIammatory factors and ceIIs in APAP hepatotoxicity,as weII as protection strate-gies of chemicaIs and naturaI products.

Objective To investigate the changes of bone mineral density (BMD) and bone mass and the influencing factors in patients with hemiplegia.Methods The total BMD, bone mass, lean mass and fat mass of 366 patients (313 stroke cases and 53 TBI cases) with hemiplegia were tested by dual-energy X-ray absorptiometry, as well as the clinical features of all patients, were studied.Results The bone masses in the paretic side (upper limb, lower limb and trunk) decreased significantly compared with nonparetic side ( P<0.01); the differences of bone masses (%) in upper limb, lower limb and trunk between paretic and nonparetic side decreased with duration of disease or trauma ( P<0.01). The multivariable stepwise regression analyses showed that the total bone mass and total BMD were negatively correlated with age and duration of disease significantly (all P<0.01), and positively correlated with body mass index (BMI) significantly ( P<0.01), the total BMD was also positively correlated with lean mass ( P<0.01) and ADL level ( P<0.05).Conclusion The bone mass deceases in the paretic side significantly, and gets worse with the duration of disease. Age, duration of disease or trauma and BMI influence total BMD and bone mass; in addition, total BMD is correlated with total lean mass and ADL level.

Objective To identify the risk factors for osteoporosis in patients with hemiplegia. Methods The total body bone mineral density (BMD) of 366 patients with hemiplegia in the stage of rehabilitation was measured with dual-energy X-ray absorptiometry. The data of the patients were analyzed with multiple logistic regressions. Results The incidence of osteoporosis was 15.3 % (56/366) in the cohort. ≥60 years old (OR=5.434, 95% CI:2.734～10.801), duration of disease (OR=1.046, 95% CI:1.013～1.080), body mass index (BMI) (OR=0.746,95% CI:0.622～0.840),ADL level (OR=0.618, 95% CI: 0.444～0.858) were independently correlated with osteoporosis in patients with hemiplegia. Conclusion Patients with hemiplegia in the stage of rehabilitation were at a high risk of osteoporosis. Aged over 60 years old, lower BMI, longer duration of disease and ADL level were independent risk factors for osteoporosis, which called for supervision and prophylaxis on osteoporosis.

Objective To investigate any effects of rubbing acupoints on the right leg on activation and deactivation responses in the human cerebellum. Methods Ten male, healthy, right-handed subjects were examined using functional magnetic resonance imaging (fMRI) while their Zusanli (ST36) , Yanglingquan (GB34),Fenglong (ST40) and Sanyinjiao (SP6) acupoints on the right lower extremity were stimulated. A block-designed method was applied. A piece of sponge was used to rub all the above-mentioned acupoints for stimulation. The mean values of the activation and deactivation signals in different cerebellar zones induced by stimulating each acupoint were calculated.Results Each acupoint could modulate cerebellum function in its specific way, but all acupoints induced the largest mean values in the Vermis Crus I area. The largest deactivation effects for all acupoints except Sanyinjiao were located in the Vermis VI area. For each acupoint, left and right side activation effects of the 20 zones of the cerebellum were basically consistent, though the mean values of most zones were higher on the right side. Conclusions The four acupoints studied not only shared common modulating effects, but also showed point-specific influence on cerebellum function. The effects exerted by each acupoint on the Vermis were greater than that on the cerebellar hemispheres. The phenomena observed in this study could contribute to acupoint selection during rehabilitation.

Lysophosphatidylcholines belong to a group of lipid components which have a variety of physiological functions. LPCs are known to be linked to metabolic disorders and cardio-vascular diseases,including diabetes,atherosclerosis and dyslip-idemia.LPCs are actively metabolized in liver,which is closely related with liver diseases and hepatotoxicity.The role of LPCs in liver diseases and hepatotoxicities has been extensively investi-gated recently.This review focuses on lysophosphatidylcholines as a biomarker for liver diseases,such as hepatic carcinoma, cholestasis,cirrhosis,hepatitis,and chemical hepatotoxicities, trying to lay a basis for investigation and therapeutics of liver dis-eases.

Objective To investigate the feasibility and therapeutic effect of stenting therapy by using modified Y-shaped self-expandable metal stent for the stenosis of gastroenteric stoma. Methods According to the particular anatomic structures and the pathological features of the narrowed gastroenteric stoma,the authors designed a modified Y-shaped self-expandable metal stent. Under the fluoroscopic guidance,implantation of modified Y-shaped self-expandable metal stent was performed in 5 patients with narrowed gastroenteric stoma. The technical safety and the clinical results were evaluated. Results The modified Y-shaped self-expandable metal stent was successfully implanted with one procedure in all five patients. After the implantation the symptoms such as nausea,vomiting,abdominal distension were promptly relieved,and the patients' living quality was markedly improved. Conclusion The stenting therapy with modified Y-shaped self-expandable metal stent can rapidly relieve the stenosis of gastroenteric stoma once for all. The technique is feasible and the short-term effect is reliable,therefore,it is worth popularizing this therapy in clinical practice.

康复医学是以恢复患者功能为中心的医学分支。因此，功能评定无论是在客观地评定患者的功能方面，还是在最终评定治疗结果和康复效率方面都是极为重要的。全面的功能评定包括躯体、精神、言语和社会四个方面。其中，言语、社会功能和认知功能中的思维方式，都具有强烈的民族文化色彩。因此，每个国家都应该有切合自己国情的功能评定方法。但由于我国康复医学发展较晚，至今尚无一套既切合国情，又全面、实用和可靠的功能评定方法。有鉴于此，我们在“中心”顾问室、神经康复科、脊髓损伤康复科、言语治疗科、心理科和老年病科的通力合作下，经过近2年的研究，在吸收国际先进经验的基础上，密切结合国情，设计了本文所述的综合功能评定法。其优点有：1．在饮食、起居等生活方式方面以及在言语、社会、思维等方面，均切合我国国情。2．评定结果采用群众熟悉的100分制，使医务人员、患者和患者家属均易于理解，便于交流和沟通。3．在言语、认知等功能的评定方面，直接由言语和心理学家选择一些简易的言语和心理学测试项目，提高了量表的准确性、全面性和可靠性。4．各项评定指标的量化程度高，在言语、认知和社会方面尤其如此，克服了一些量表中对此类项目的评定指标不够具体和不易掌握的不足。5.简便实用，一次检查对正常人仅需20分钟左右，对患者则无负担。6.本法已在128名正常人中应用，并求出了正常值，据此拟定了功能障碍严重程度的等级，可供参考和应用。7.信度经过检验，证明可靠。 综合功能评定法的正常值、功能障碍严重程度分级及信度研究结果，将陆续报道。

: Rehabilitation medicine is a medical branch which focused on functional recovery. Function Evaluation is very important in assessing the function of patients, the effect of treatment and the efficiency of rehabilitation. Comprehensive Function Evaluation includes evaluation of physical, psychological, speech and society. Vocal, mental and social evaluation have deep cultural and national background. Therefore every country must have its own Function Evaluation Method. Now we present our design for Comprehensive Evaluation. Based on the cooperation of Department of Rehabilitation, Department of Neurology, Department of Spinal Cord Injury, Department of Speech Therapy and Department of Psychology. The advantages of this method are as follows: 1. The style of ADL, speech and thinking are suitable for the condition of our country. 2. The evaluation result adopts hundred work system, it is easy for medical staff, patients and their family to understand and communicate the result. 3. We make it more accurate, comprehensive and reliable by some simple tests on speech pathology and psychology. 4. We overcome some disadvantages of evaluation indexes because it is not correct and is difficult to be understood before. Now every evaluation index has quantity standard. 5. It is simple and practical. Each subtest takes 20 minutes or more. 6. It has been tested by normal people. The norm and severity grade had been developed. 7. The reliability is tested and is proved to be dependable.

Objective To evaluate the effectiveness of Lingshao-Zaoren granule in the treatment of female overactive bladder. Methods A total of 60 female OAB patients who met the inclusion criteria were randomly divided into 2 groups, 30 cases in each group. The control group recieved the Tolterodine Tartrate Sustained Release Tablets and the Lingshao-Zaoren granule placebo, and the treatment group used the Tolterodine Tartrate Sustained Release Tablets and the true Lingshao-Zaoren granule treatment. Both groups were treated for 4 weeks. Overactive bladder symptom scale (OABSS) was used to determine the severity of OAB.Results After treatment 14,28 d,OABSS scores of the treatment group(5.3 ± 2.3,1.4 ± 1.2 vs.8.4 ± 2.4,F=137.209),and control group(7.8 ± 1.9,6.8 ± 1.4 vs.8.6 ± 2.6,F=8.927),were significantly lower than the baseline of each group respectively (P<0.01). Besides, OABSS scores of the treatment group after 14 and 28 d were significantly lower than the control group (t=4.668, 15.678, P<0.01). The pain scores (5.9 ± 1.9, 2.7 ± 1.1 vs.9.5 ±2.3,F=108.819)of treatment group at 14 and 28 d were significantly lower than the baseline(P<0.01);and the pain scores of treatment group at 14 and 28 d were significantly lower than the control group (t=6.342, 14.812,P<0.01).The lower abdomen discomfort scores at 14,28 d in treatment group(1.9 ± 1.4,1.1 ± 1.0 vs. 3.3 ±1.1,F=28.762),and control group(2.7 ±1.0,2.4 ±0.8 vs.3.4 ±1.2,F=12.103)were significantly lower than the baseline of each group (P<0.01); and the abdominal discomfort scores of treatment group at 14, 28 d were significantly lower than the control group (t=2.521, 5.041, P<0.05 or P<0.01). Conclusions The Lingshao-Zaoren granule could decrease OABSS score,pain score,abdominal discomfort symptoms,improve clinical symptoms of the female patients with OAB.
