Cancer has become the leading cause of mortality in the urban area of China. Whole body diffusion weighted imaging (WB-DWI), also known as virtual positron emission tomography, has gradually become accepted as an image tool in tumor localization, characterization, staging and monitoring response to therapy or tumor recurrence. Our article aimed to summarize the limited initial clinical use of WB-DWI in the referred area, and to analyze the most potential advantage of WB-DWI in therapeutic monitoring and tumor staging. WB-DWI as a highly sensitive, completely non-invasive, well-tolerated and low price technique has a promising furture in tumor assessment. Profound clinical study is necessary for its further application improvement.

Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.

The aim of this study is to investigate the protective effect of N-[2-(4-hydroxyphenyl)ethyl]-2-(2, 5-dimethoxyphenyl)-3-(3-methoxy-4-hydroxyphenyl)acrylamide (FLZ), a novel synthetic squamosamide cyclic derivative, against Parkinson's disease (PD) model mice induced by the inflammatory bacterial endotoxin, lipopolysaccharides (LPS) and the neurotoxin 1-methy-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP). C57/BL mice were ip injected LPS (5 mg x kg(-1)) once. One week following the LPS injection, mice received a subcutaneous injection of MPTP (25 mg x kg(-1)) once daily for 2 days. Eight weeks later, FLZ (25, 50 and 75 mg x kg(-1)) was orally administered to mice once daily for 60 days. The motor ability of the mice was evaluated by rod climbing test and footprint test. The dopamine (DA) levels in mouse striatum were determined by high performance liquid chromatography system. The tyrosine hydroxylase (TH)-positive cells were showed by immunohistochemical analysis. FLZ treatment significantly improved motor dysfunction of mice challenged by LPS plus MPTP. The increase of TH-positive cell numbers and elevation of DA levels may be contributed to the beneficial effects of FLZ on motor behavior. This study showed FLZ has significant therapeutic effect on LPS plus MPTP induced chronic PD model, which indicates its potential as a new candidate drug to treat PD.

Objective To investigate the effect of Mepilex on pressure sores in patients at lateral position after craniocerebral surgery.Methods Toally 60 patients lying at lateral position after craniocerebral surgery were randomized into two groups in equal number with random digit table:the control group and experiment group.In the control group,Gel pad was used to prevent and treat the pressure sores and in the experiment group Mepilex was used between the compressed skin and operation table before setting the position.The skin conditions of the two groups were observed after operation.Result The prophylactic effect of pressure sore in the experiment group was significantly better than that in the control group (P＜0.05).Conclusion Mepilex can prevent the skin pressure sores in the patients at lateral position after cerebral surgery.

Objective To investigate the effect of electromyographic biofeedback with electric stimulation (Est-EMGBFT) training on dorsiflexion of foot of cerebral palsy children with spastic diplegia type.Methods 66 cerebral palsy children with spastic diplegia type were randomly divided into the treatment group and control group with 33 cases in each group. The treatment group was treated with rehabilitation training plus Est-EMGBFT, while the control group with rehabilitation training only. The manual muscle test (MMT) of tibial muscle and the ankle joint initiative range of motion (I-ROM) were performed before and after 4 courses of treatment, and the treatment group was assessed by electromyographic (EMG) apparatus additionally.Results After treatment, the muscular force of children in the treatment group was higher than those in the control group significantly ( P<0.01) and the level of integrated electromyography (iEMG) and root mean square (RMS) assessed by sEMG increased significantly ( P<0.05), the I-ROM of the treatment group was higher than the control group significantly ( P<0.05).Conclusion Est-EMGBFT training can provide a satisfactory rehabilitation effect for the dorsiflexion of foot of cerebral palsy children with spastic diplegia type.
