Metabolomics is one of the branches of systems biology,which employs nuclear magnetic resonance and mass spectrometry technologies to detect the abnormal metabolites from a variety of body fluids. Study of various molecules and their functions may help to find the disease-related early metabolic marker clusters,understand the molecular mechanism of pathogenesis,which provides broad prospects for the early diagnosis and individualized treatment of malignant tumors.

Objective To explore effective nursing intervention through clinical analysis of middle ear function of children with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods Tympanogram was obtained from both pre-operation and post-operation in 413 OSAHS cases(the OSAHS group).Audiogram was conducted if the tympanogram was abnormal.There were 279 cases of normal children in the control group.The incidence of middle ear function loss of two groups were compared.Results 288 cases(328 ears) had some degree of middle ear dysfunction,accounting for 69.73％.69 cases had some degree of hearing loss,accounting for 16.71％.The incidences of middle ear dysfunction and degree of hearing loss in the OSAHS group were higher than 7.53％ and 1.43％ of the control group.The hearing ability was gained after operation in both groups.Conclusions The incidence of middle ear dysfunction is higher in children with obstructive sleep apnea hypopnea syndrome.But the bad influence alleviated with age.Therefore,early detection,timely treatment and effective nursing can achieve good effect.

Objective To explore the impact of executive function intervention on the executive functioning of elderly patients with cerebral infarction,and to seek the best way to improve executive function in such patients.Methods Eighty elderly patients with cerebral infarction were randomly divided into an intervention group and a control group.A series of executive function interventions were administered to those in the intervention group with no intervention in the control group.The two groups were given the same conventional medication.The Behavioral Assessment of the Dysexecutive Syndrome (BADS) was taken before the intervention,then 3 months and 6 months after recruitment.Results In the intervention group the average score and the total standard score had increased significantly after 3 months except for the action program test and the modified six elements test.Both indicators were still significantly increased from the baseline afar 6 months except for the modified six elements test.The average score and the total standard score had increased significantly between 3 months and 6 months except on the key search test.Both the time determination test and the total standard score had statistically significant average differences.The control group showed no significant differences.After 3 months,the average scores and the total test standard scores in the intervention group were signifieantiy higher than those in control group except on the action program test.The rules conversion card test,the time determination test and the total standard score difference all showed statistically significant differences between the groups.After 6 months the intervention group's scores remained significantly higher than those of the control group except on the action program test.Conclusions Executive function interventions are effective in delaying the progress and improving the prognosis of executive dysfunction in elderly patients with cerebral infarction,and the therapy has persistent effects.

Hoxa gene plays an essential role in the generation and development of the human female reproductive system. This gene is expressed in the Mullerian duct and the adult female reproductive system. Expression of Hoxa10 dramatically increased during the midsecretory phase of the menstrual cycle, corresponding to the time of implantation. Female mice lacking Hoxa10 have a uterine factor defect that results in death of the preimplantation embryo and failure of implantation. These results suggest Hoxa10 may have an important function in implantation. Hoxa10 - deficient males exhibit cryptorchidism that lead to male infertility.

OBJECTIVE: To seek the bionic material myocardial extracellular matrix in the myocardial tissue engineering for the cultured myocardial cells and to provide a reliable scaffold.METHODS: A computer-based online search of CNKI and PubMed database to search articles published between January 1996 and August 2007 on scaffold material of tissue engineering.RESULTS: Natural biological scaffold materials with good biocompatibility and mechanical properties are ideal choice in the cardiac tissue engineering rapid prototyping technology. Natural biological materials such as collagen, chitosan have poor mechanical properties and plasticity, but good biocompatibility, which can be used for rapid prototyping of cardiac stents. The scaffolds which are prepared by the technology such as three-dimensional printing, laser sintering, three-dimensional pressing,selective laser sintering rapid prototyping technology on have the advantages such as high porosity, high surface area volume ratio,completely transparent among the holes, controllable macro-shape, porosity, and independent control of aperture.CONCLUSION: Through the use of dispersion/accumulation forming principle, surface modification of traditional biological materials in cardiac tissue engineering using computers and other high-tech nano-polymer technology is expected to provide ideal myocardial scaffolds.

Objective To observe the clinical effects of anterior plates with titanium mesh and bone graft (auto and allo) in treatment of cervical spine fractures. Methods 42 cases of fractures of cervical spine treated with anterior plates with titanium mesh. Results The bone graft (auto and allo) were followed up for 4 to 28 months (mean 17 months). The preoperative and postoperative nerve functions were evaluated according to JOA criteria. The cervical curvatures, sink or shift of the mesh and bone fusion were evaluated by X rays. There were no significant complications during perioperative periods. The functions of spinal cord were improved, the cervical curvatures were restored, and no sinking or shifting of the mesh was observed. There was also no loosening of plate or screw. The fusion began 3.5 months postoperatively, and a good fusion could be observed 1 year postoperatively. Conclusion By application of anterior plates with titanium mesh and bone graft (auto and allo) in treatment of cervical spine fractures, the cervical curvature and stability can be restored, the iliac lesion and long operation duration caused by the harvest from ilium can be avoided, better fusion and quicker recovery can be obtained.

Cerebral small vessel disease is a common cerebrovascular disease in clinical practice.It is mainly characterized by insidious onset and slow development.Some may have acute attack.The imaging features of cerebral small vessel disease mainly include cerebral white matter lesions,lacunar infarction,cerebral microbleed and cerebral perivascular space expansion.It is closely associated with cognitive impairment.All imaging findings can occur simultaneously and interact,further aggravate cognitive impairment,and ultimately lead to dementia.Therefore,the influence of cerebral small vessel disease on the quality of life and social function of the patients cannot be ignored.
