Hepatocellular carcinoma (HCC) is one of the most common malignancies.Current radiological examination is quite limited in diagnosing early HCC.Various treatments for HCC have definite indications,and there is still no effective treatment and prevention for recurrence and metastasis.Based on the recent development of molecular targeting nanotechnology for specific molecules in liver cancer cells,early diagnosis and the monitoring of recurrence and metastasis for HCC can be improved,and the specificity of drug in targeting cancer cells and the therapeutic effect on HCC can be significantly enhanced.The article reviewed the application and significance of molecular targeting nanotechnology in HCC diagnosis and treatment.

Objective To study the effects of electromyography-triggered neuromuscular stimulation on upper extremity functional recovery of acute stroke patients. Methods 60 stroke patients who lost wrist extension even in the electromyography (EMG) within 4 weeks were randomly assigned to experimental group and control group. The experimental group received electromyography-triggered neuromuscular stimulation, and the control group received neuromuscular stimulation. They were assessed with EMG, Fugl-Meyer assessment (FMA), Barthel index (BI) before and 4 weeks after treatment. Results The EMG, scores of FMA and BI improved in all the patients after treatment (P=0.000), and improved more in the experimental group (P<0.05). Conclusion Electromyography-triggered neuromuscular stimulation can improve the motor function of hemiplegia, even in the patients without change of EMG.

Age-related macular degeneration(AMD)is a kind of degenerative diseases with complex pathogenesis and stimulation of multiple factors.It has become one of the major diseases causing-blindness in the elderly population in China.Recently,some epidemiological findings demonstrated that diabetes mellitus possibly is one of risk factors for AMD,and this will offers a new approach for the prevention and treatment of AMD.Thus,it is very important for US to strengthen the research of mechanism of AMD impacted by diabetes mellitus,pay more attention to the progress of AMD,search for a scientific and rational therapeutic way of improving the prognosis and elevate the quality of life in the patients with diabetes mellitus.

Aim This was to study the effects of hydroxysafflor yellow A(HYSA)on iNOS expression in rats following focal cerebral ischemia. Methods Rat cerebral ischemia-reperfusion injury was induced by middle cerebral artery occlusion. The expression levels of iNOS were examined using immunohistochemical method. The neurological outcome and the cerebral infarct area were evaluated. Results The expression levels of iNOS in HYSA groups were significantly lower than those in ischemic model group. Treatment with HYSA also decreased the cerebral infarct area and the neurological deficit score. Conclusion HYSA induced down regulation of iNOS expression, which may mediate the protective effect of HYSA on cerebral ischemia.

Objective: To study the pharmacological effects of Zhong Feng Kang on model mice with cerebral ischemia and after restoration of blood flow. Methods: To make the model of cerebral ischemia and after restoration of blood flow with thread embolism, and measure the area of cerebral infarction and observe cerebral pathologic change. Results: Zhong Feng Kang could reduce the area of cerebral infarction, improve cerebral pathologic change on model mice. Conclusion: The results confirmed that the clinical data of Zhongfengkang would provide a basis of pharmaceutical application

The toxicity of Chinese materia medica (CMM) is one of cores of the property theory of CMM. From the perspective of history, the literature source of the understanding on CMM toxicity was traced; The traditional and contemporary understanding about the meaning and classification of CMM toxicity was compared and analyzed; The ideas on CMM toxicity with the feature of tradition, experience, objectivity, the integrity of the concept, and some of the controllability were proposed; The theory and practice of traditional Chinese medicines should be combined in order to effectively integrate and apply various modern scientific and technical methods, and create new ideas about toxicity studies of CMM, which has the important significance on the comprehensive understanding about CMM toxicity, strengthening the research on CMM toxicity, and promoting the safety of CMM in clinical use.

Objective To investigate the change of P300 of the attention - deficit/hyperactivity disorder children before and after they took litalin, according to this objective subject to guide the clinical treatment of ADHD children. Methods Using the looking se-ducible electricity stimulates 22 ADHD children, and check the change of latency and the rate of the wave before and after they took litalin. Results After ADHD children took litalin, their latency of P300 has decreased clearly, and the amplitude had no change. Conclusion The changes of P300 latency in ADHD children after they took litalin can be adopted as the guidelines of clinical treatment for the ADHD children.
