Objective To understand the effect of environment variables on anxiety in the soldiers at high altitude.Methods A total of 267 soldiers at high altitude were investigated with the self-rating anxiety scale,the environmental scale and Eysenck personality questionnaire.Results Compared with norm(29.78±0.46),the soldiers at high altitude had higher sore of anxiety(37.22±6.64;t=17.92,P＜0.01).One-way ANOVA and independent.samples t test showed that the anxiety(38.37±5.93,36.65±6.951,36.75±6.88)of military people at high altitude had not evidently difference in different altitude(≥3587.5m,3587.5～2767.9m,≤2767.9m).Parental culture.length of military service(F=3.25,P＜0.05)and neuroticism(R=0.52,P＜0.01)had evidently effect on the depression of soldiers.Conclusion The occurrence of anxiety in the soldiers at high altitude has a higher level.Parental culture.1ength of military service and neuroticism had predictive value for depression.

Patients who have received coronary artery interventional therapy exhibit visible anxiety and depression, which is closely related to prognosis and life quality. Therefore, for coronary artery stent patients,exception of anticoagulation and antihyperlipedemic drugs, psychological support, cognition therapy and distorted behavior rectification should be applied. The medication of anti-anxiety or depression is of great importance in ameliorate mental state, relieve mental load, as well as enhance prognosis of patients.

A large number of epidemiological studies have indicated that periodontal disease and ischemic stroke have a certain correlation, which may be its independent risk factor, but the exact mechanism is not fully understood. This article reviews the epidemiological studies of periodontal disease and ischemic stroke as well as its possible mechanism of action.

Objective:To design a new rehabilitation system for cerebral apoplexy patients, and help patients complete rehabilitation treatment on the bed.Methods: Design the basic structure of the system through mechanical technology, make the realization of the function by using circuit and wireless control system, global-eye system was embedded in it by using the principle of the 3G to 4G intelligent technology for improving the humanized design of the system. Results:Through application in physical therapy, nursing, clinical rehabilitation, and clinical therapy in hospitals, it achieved good economic and social benefits, got the recognition of patients, clinicians and rehabilitation therapists. Conclusion: It can be used for the treatment of cerebral apoplexy, reduce medical expenditure, save amount of social resource and improve the work efficiency of medical staff.

Objective To investigate the immunoregulatory effects of immunonutrient ?-3 polyunsaturated fatty acid (PUFA) and its applications in organ transplantation. Methods Relevant literatures of recent years were reviewed. Results The immunoregulatory effects of ?-3 PUFA can inhibit proliferation and activation of the immunocompetent cells including T cell and B cell, reduce cytokine production, modulate immunologic response, improve graft function, pro-long survival, reduce episodes of rejection, and lessen adverse reactions of immunosuppressor.Conclusion ?-3 PUFA should have wide applications in organ transplantation due to its immunoregulatory effects. However, this research should be further studied.

BACKGROUND: Construction of lentivirus vector has the advantages of simplicity,it is regard as the most effective and successful method in transgene therapy. OBJECTIVE: To clone the metastasis suppressor gene KiSS-1 from human normal placenta tissue and construct its lentivirus vector. DESIGN,TIME AND SETTING: The open experiment was performed at the Laboratory of Fujian Normal University from September 2006 to December 2007. MATERIAL: The pNL-IRES2-EGFP vector was conservated by the Laboratory of Fujian Normal University. METHODS: Total RNA was extracted from human placenta tissue. The opening reading frame cDNA of KiSS-1 was isolated by using RT-PCR,and cloned into its lentiviral vector pNL-IRES2-EGFP to construct expression plasmid pNL-IRES2-EGFP-KiSS-1. MAIN OUTCOME MEASURES: Clone objective gene fragment of KiSS-1,restriction enzyme digestion and gene sequencing of the recombinant plasmid pNL-IRES2-EGFP-KiSS-1 were observed in the study. RESULTS: The nucleotide sequence isolated from the recombinant plasmid pNL-IRES2-EGFP-KiSS-1 was confirmed the same as expected by restriction enzyme digestion and gene sequencing. CONCLUSION: The recombinant plasmid pNL-IRES2-EGFP-KiSS-1 has been constructed successfully.

Objective To research the tissue structure changes of vessels wall in the patients with liver cirrhotic portal hypertension and to investigate the role of inducible nitric oxide synthase (iNOS) in development process of liver cirrhosis.Methods The left portal vein,left hepatic artery and left hepatic vein (n=27) were collected from the patients with liver transplantation as the case group and the corresponding vessels of traumatic hepatectomy were collected as control group (n=15).HE staining and Masson staining were performed respectively.The hepatic arteries were stained with elastic fibers and immunized with anti-human iNOS polyclonal antibody.Results Compared with the control group,the portal vein intima and tunica media in the case group were thickened,the smooth muscle cells of tunica media were hyperplasia and hypertrophy,partial smooth muscle cells protruded into the intima;the irregular proliferation of hepatic arterial intima,arterial luminal stenosis,internal elastic membrane flatten,and even fracture,the tunica media smooth muscle hyperplasia to the intima were also observed;no obvious structural changes were observed in the hepatic vein wall.The higher expression of iNOS was found in the cytoplasm of hepatic artery smooth muscle cells (P<0.01).Conclusion The walls of liver artery and portal vein in the patients with liver cirrhosis would secondarily develop the tissue structure reconstruction,which is the results of human body′s own compensatory mechanism,the higher expression of iNOS accelerats the occurrence and development of the tissue structure reconstruction.

The acurate diagnosis of invasive fungal infection(IFI)is the key point for the treatment and proginosis for IFI patients.Pathological diagnosis is still considered as the gold standard for the IFI diagnosis although difficult.The regular procedures for IFI diagnosis including culture and direct examintion are often low yeilding,the discrimination for contamination and infection is hard.Imaging manifestations are nonspecific but have important suggestive values.The detection for molds antigen content is useful,but its sensitivity and specifity need to be improved.The proper diagnosis for IFI relys on the combination of clinical characteristic,imaging manifestion and serial observation.
