OBJECTIVE To explore the incidence of the nosocomial infection in patients with mental diseases,(analyze) the correlative factors and then reduce the incidence.(METHODS) By using the retrospective method,the(inpatient) cases in psychiatry department from Jan 2000 to Dec 2004 were surveyed and statistically analyzed.(RESULTS) There were 313 cases of nosocomial infection from 9 089 inpatients with mental diseases.The infection rate was(3.44%.) The total rate had been dropped year by year.The major sites of the infection were the(upper)(respiratory) tract(34.82%),the gastrointestinal tract(20.45%) and the urinary system(18.53%).The(infection) rate in ladies patient area(3.83%) was significantly higher than that of gentlemen patient area(3.07%)(P

MicroRNAs ( miRNAs) are small noncoding RNAs that post transcriptionally regulate the gene expression , involving in the process of growth , development , aging and death of organisms .It has been demonstrated that miRNAs were associated with the structure and function of blood vessels and heart , involving in the aging process of blood vessels and cardiomyocytes .For example , miR-29, miR-34a, miR-217, miR-146a may participate in the regulation of aging blood vessels;miR-21, miR-22, miR-18, miR-19 may emerge as the regulators of aging cardiomyocytes .These miRNAs may function as the novel biomarkers for the cardiovascular ag-ing.This article reviews the current studies on miRNA and cardiovascular aging .

Objective To observe the prevalence of impaired glucose regulation (IGR) in ischemic stroke patients with or without inter-or extra-cranial arteries occlusive disease,and to analyze the relationship of IGR with large arteries occlusive disease.Methods lschemic stroke patients without diabetes history and with FPG

Objective To explore the treatment effect and mechanism of A-NK cells on the subcutaneous trans?planted tumor of oral tongue squamous cell carcinoma in nude mice through observing the external growth and hyperplasia of A-NK cells and to provide theoretical evidence for squamous cell carcinoma treatment. Methods A-NK cells and NA-NK cells were both derived from healthy human peripheral blood and cultured in vitro. Cell growth was observed under micro?scope. The squamous cell carcinoma model in nude mice was established through subcutaneous implanting of Tca8113 cells. Then they were randomly assigned into three groups who were injected with either saline solution, or A-NK cells or NA-NK cells paraneoplastically. All animals were sacrificed after 33 days when tumor were isolated then weight and change in tumor size were assessed. Finally curve of tumor growth was drawn. Results Under the microscope, the proliferation of A-NK cells peak in 15 days and NA-NK cells peak in 12 days. After 3 weeks, the number of A-NK cells increased by 39.33 times while the number of NA-NK cells increased by 16.33 times. The Volume of tongue squamous cell carcinoma in saline solu?tion group was larger than that in A-NK cells and NA-NK cells groups, and volume in the NA-NK cells group was larger than that in A-NK cells group. The volume of tongue neoplasms in different groups, time, and interaction effects are statisti?cally significant (P<0.01). The tongue neoplasms weight in the saline solution group was greater than that in the A-NK cells and NA-NK cells group, and the weight in NA-NK cells group was greater than that in A-NK cells group, and the difference are statistically significant (P<0.05). Conclusion A-NK cells and NA-NK cells can significantly inhibit the subcutane?ous transplanted tumors in nude mice and the anti tumor effect of A-NK group is stronger than NA-NK.

The risk factor of dental fluorosis are mainly related to the cancen tration of fluoride in the drinking water,the supplements of fluoride,nutrition states and regime,the time of fluoride exposure.Other factor such as the period of mother's milk feeding,the altitude of resident,the environmental pollution,the education degree of parents,and the level of health service of the community are also contributed to the development of dental fluorosis.Besides,the knowledge of dentists,the health habits of individual,the condition of economic,and so on is somehow the risk factor of dental fluorosis.The chances of fluoride exposure will become more often as the prosperous of the society.Thus any health policy of the complement of fluoride should be adapted to local conditions.
