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.

Objective To observe the effects of White Mange Mixture on the content of VEGF and the genetic and protein expressions of VEGFR-2 of HaCaT cells;To explore its mechanism. Methods HaCaT cells were cultured in vitro to establish psoriasis experimental model. SD rats were randomly divided into the blank serum group, white mange mixture of low-, medium- and high- dose groups and acitretin group, meanwhile to set up blank control group. Cultured HaCaT cells model were intervened with different medicine serum. ELISA was applied to detect the content of VEGF. RT-PCR and Western blot were used to detect the genetic and protein expressions of VEGFR-2.Results Compared with the blank control group, White Mange Mixture of low-, medium- and high-dose groups interventing HaCaT cells could obviously inhibit the secretion of VEGF and decrease the genetic and protein expression of VEGFR-2 in a dose-dependent manner. Conclusion White Mange Mixture plays a role in the treatment of psoriasis possibly through inhibiting the content of VEGF and decreasing the genetic and protein expressions of VEGFR-2.

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.

Objective To investigate the effects and mechanism of Xiaomin granules on type Ⅰ hypersensitivity.Methods The experimental animal model was made for type Ⅰ hypersensitivity.The mice were divided into five groups named vacant control group,Xiaomin granules(low-,middle-and high-dose) group,chlorpheniramine group randomly and were given homologous medication respectively.Results Xiaomin granules can inhibit capillary penetrance caused by histamine and 5-HT in mice(P 0.05).Xiaomin granules could inhibit the mice hind paw edema degree caused by histamine.The further study found that Xiaomin granules could decrease anaphylactic shock of the mice and decrease the death rate.Conclusions Xiaomin granules could restrain type Ⅰ hypersensitivity by inhibiting inflammatory mediators.

Objective To study the expression of HOXA10 gene in the endometrium of normal fertile women and patients with unexplained infertility during different phases of menstrual cycle. Methods Endometrium samples were obtained by curettage in 52 normal fertile women and 38 patients with unexplained infertility during different phases of menstrual cycle, HOXA10 mRNA expression were detected by in situ hybridization and reverse polymerase chain reaction (RT-PCR). Results (1) HOXA10 mRNA were detected in the glandular and stromal cells of endometrium of fertile women during the menstrual cycle. By in situ hybridization (positive unite, PU), HOXA10 mRNA levels were significantly higher in the mid-secretory phase [glandular cells (G) 5.69?0.57,stromal cells (S) 7.48?0.67] and late-secretory phase(G 5.99?0.40,S 7.98?1.08) than those in late proliferative phase (G 3.35?0.20,S 3.20?0.37) and early secretory phase (G 3.07?0.26,S 3.18?0.27)(P

Bone marrow transplantation was considered effective treatment for leukemias and other haematological diseases. Acute graft v-host disease (GVHD) is a major complication of allogeneic bone marrow transplantation. The T lymphocytes were specially depleted by anti-CD5, CD2, CD8, CD27 monoclonal antibody-ricin immunotoxins. Inhibition of the protein synthesis and T-cell functions in the target cells was observed in vitro. At 10 9mol / L of the immunotoxin, 3 logs (99.9%) of target cells were killed, but no cytotoxicity on nontarget cells. At the same concentration, the anti T cell immunotoxin had no any influence on the proliferating rate of CFU-GM and BFU E. None of the ten patients who received T cell depleted bone marrow developed grade III or IV acute GVHD.
