Objective To understand the cognition of ICU syndrome by ICU nurses in Guangdong province. Methods Through questionnaire filling in, this investigation was made on the first hatch of ICU nurses dispatched to Hung Kong for ICU specialized training by Guangdong province. Information collected included the nurses' personal information and their knowledge about ICU syndrome. Results The sub-jects' knowledge about ICU syndrome was scanty, and was not related to their years of work, professional ti-tles, academic degrees or administrative duties. The overwhelming majority of the subjects had not paid at-tention to the disease in clinical work. Most departments had not formulated guidelines whatsoever on nurs-ing for ICU syndrome. In assessing the ICU syndrome, the vast majority of nurses relied on their clinical experience, with none of them relying on the confusion assessment method for the intensive care unit (CAM-ICU). Only very few of the subjects acquired some knowledge about the syndrome during their study at colleges. Conclusions The ICU nurses in Guangdong province should attach importance to ICU syn-drome and strengthen the study of related knowledge in their work and study. And it is essential to popular-ize CAM- ICU and to build a standard assessment system and work out the intervention measures for ICU syndrome.

Objective To investigate the effects of repetitive transcranial magnetic acupoint stimulation on hemiplegic patients.Methods60 hemiplegic patients were assigned to treatment group and control group(30 cases for each group). Both groups received rehabilitation therapy. Meanwhile, the treatment group received repetitive transcranial magnetic acupoint stimulation. Fugl-Meyer Assessment (FMA), The Mini-Mental State Examination (MMSE), Barthel Index(BI) were used to measure the outcome.ResultsThe scores of FMA and BI increased significantly in both groups after treatment. However, these scores in treatment group improved more compared with those of control group(P<0.05).ConclusionRepetitive transcranial magnetic acupoint stimulation is helpful to improve the motor function, and ability of daily living of hemiplegic patients.

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by memory loss and cognitive decline. The pathological eatures of Alzheimer's disease are abnormal deposition of amyloid beta-peptides (Aβ), neurofibrillary tangles, cholinergic deficits, and loss of synaptic processes and dendritic spines. Senescence accelerated mouse prone 8 exhibits age-related deficits of learning and memory from an early age, tau protein phosphorylation, neurotransmitter changes, synaptic structure and function disorders, circadian rhythm disorders,as well as gene expression and many other characteristic changes, which are consistent with Alzheimer's disease pathological changes，and can be used as an ideal animal model for Alzheimer's disease prevention drugs development.

Objective To study the effects of Traditional Chinese Medicine(TCM)therapy on shoulder hand syndrome(SHS).Methods 50 patients with SHS were divided into rehabilitation group and control group.The patients in rehabilitation group accepted physiotherapy and TCM therapy,which include marinate in traditional herb,pulsed electromagnetic therapy,massage and stimulate point.The patients in control group accepted physiotherapy only.They were evaluated after 1 month.Results The cured rate and the improved rate in rehabilitation group were higher than those in control group(P<0.05).Conclusion The TCM therapy is effective on SHS.

Background It is well known that tissue factor (TF) is expressed in tumor cells and neovascular endothelial cells of tumor.It plays an important role in the formation of new blood vessels as well as the growth and metastasis of tumor.However,whether TF is expressed or not in choroidal melanoma(CM)is unclear.Objective This study is to investigate the expression of TF in a choroidal melanoma cell line and human choroidal melanoma.Methods The expression of TF was studied in the optimal choroidal melanoma-1 (OCM-1) cell line and ten specimens from CM patients using immunhistochemistry.Ten normal eye specimens from donators were used as controls.Results The TF protein was mainly expressed in the cytoplasm.It is over-expressed in OCM-1 cells with positive rate of 85.33±5.47%.Hyper-expression of TF also was found in human choroidal melanoma with a positive rate of 41.60±14.17%.The integrated optical density (IOD) of positive cells in CM was 33853.67±16445.30,and only 5.65±4.26% of positive cells was found in normal human choroidal tissue.The IOD of TF expression in normal human choroidal tissue was 426.43±316.62.Conclusion The overexpression of TF in CM cells may be a new immunotherapy target for CM treatment.

Liver cirrhosis is a common chronic progressive liver disease,and at present the most effective treatment for advanced liver cirrhosis is liver transplantation.However,main reasons of limiting the wide application of liver cirrhosis are liver source deficiency,expensive cost,graft rejection reaction,the complications caused by long-term application of immunosuppressant and so on.Stem cell transplantation has become a new method for the treatment of liver diseases due to its beneficial to the damaged liver tissue repair,and it can compensate part of liver function.The basis and clinical research progress,the existing problems and prospects of the bone mesenchymal stem cell transplantation for the treatment of liver cirrhosis are summarized,aiming to provide theoretical basis for the further research.

Tetrahydrobiopterin (BH4) is an essential cofactor for all three nitric oxide synthase (NOS isoforms), which plays an important role in vascular diseases. GTP cyclohydrolase 1 (GCH 1) is the first-step and rate-limiting enzyme for BH4 biosynthesis in its de novo pathway. Common GCH1 gene variant C+243T in the 3'-untranslated region predicts NO excretion. The present study examined the predictive role of GCH 1 gene 3'-UTR C+243T variant in the long-term outcome of ischemic stroke. A total of 142 patients with first-onset ischemic stroke were recruited and detected for genotype of GCH1 3'-UTR C+243T by a TaqMan SNP Genotyping assay. Subsequent vascular events and death were determined over a 5-year follow-up period. The frequency of GCH1 3'-UTR +243 C/T or T/T genotype was significantly increased in patients with endpoint events as compared with those without events (74% vs 57.8%, P=0.06). Cox regression survival analysis indicated that an increased probability of death or new vascular events was found in patients with GCH1 3'-UTR +243 C/T or T/T genotype compared with those with GCH1 3'-UTR C/C genotype (40.6% vs 25.5%), GCH1 3'-UTR +243 C/T or T/T genotype relative to GCH1 3'-UTR C/C genotype was associated with the increased risk of death or vascular events even after adjustment for other risk factors (OR=2.171, 95% CI: 1.066-4.424, P=0.033). It was concluded that GCH1 3'-UTR C+243T variant was an independent predictor of worsening long-term outcomes in patients with first-onset ischemic stroke.
