Objective: Intelligent monitoring system of medical equipment can realize the intelligent dynamic management to equipment in the hospital wireless or wired network environment. Methods: Use of communication network, intelligent call, system monitoring and other means of science and technology to design the intelligent micro device state sensor. Results:System is mainly for hospital equipment, which can capture and management of medical equipment data. When the elderly have abnormal condition, it can send information through intelligent system, through identification and location, to realize the construction of equipment state information. Conclusion: Intelligent sensor in the system application can achieve the sharing of resources; realize the whole hand or full coverage of the intelligent health network system, providing an effective guarantee for the health of the masses.

This paper introduces such two methods for the software to detect and download its new version automatically as applying the mapped network drive in LAN and download through FTP in Internet. The implementation of auto running of the new version after update is also discussed.

Objective: To investigate the morphological changes of cerebral blood vessels by digital subtraction angiography (DSA) in patients with central vertigo, so as to provide references for diagnosis and treatment of patients with central vertigo. Methods: Ninety-two patients suffering from central vertigo were subjected to cerebral angiography through femoral artery. The types, proportion, and distribution (site predilection and number of involved vessels) of the cerebrovascular abnormalities were observed and analyzed. Results: Of the 92 patients with central vertigo, cerebrovascular lesions were found in 137 sides, including 15 (10. 95%) anterior circulation lesions and 122 (89.05%) posterior circulation lesions. Thirty-one (33.7%) patients had 2 or more lesions. The most common lesion was vertibroarterial lesion accompanied with other cerebrovascular stenosis. The lesions included 39 (28.47%) sides with vertibro-basilar stenosis or occlusion, 13 (9.49%) sides with posterior cerebral artery stenosis or occlusion, and 59 (43.06%) sides with posterior circulation abnormalities. Conclusion: The posterior circulation stenoses or abnormalities might be the major reasons for central vertigo in middle- and old-age patients.

Because of the long acquisition time and spin-echo planar imaging sequence, diffusion weight magnetic resonance image (DWI) should be denoised effectively to ensure the follow-up applications. The commonly used denoising methods which induced from gray level image lack the use of the specific information from multiple magnitude directions. This paper, therefore, proposes a modified linear minimum mean square error (LMMSE) denosing method used for DWI. The proposed method uses the local information to estimate the parameter of the Rician noise and modifies the LMMSE using the information of multiple magnitude directions synthetically. The simulation and experiment of the synthetic DWI and real human brain DWI dataset demonstrate that the proposed method can more effectively remove the Rician noise compared to the commonly used denoising method and improve the robustness and validity of the diffusion tensor magnetic resonance image (DTI).

OBJECTIVE To investigate the effect of norepinephrine (NE) on expression of interleu?kin-6 (IL-6) in human macrophages and explore its pro-inflammatory and pro-atherosclerotic mecha?nisms. METHODS Murine U937 macrophages were cultured and stimulated with 0.01-10μmol·L-1 of NE for 6, 9, 12, 24 and 48 h. The IL-6 mRNA level of 24 h was analyzed by RT-PCR, and IL-6 protein expression in the supernatant at 0, 6, 9, 12, 24 and 48 h was detected by ELISA. After 24 h, intracellular reactive oxygen species (ROS) generation was observed by DCF fluorescence. The cells were pretreated with antioxidant N-acetylcysteine (NAC), complexⅡinhibitor thenoyltrifluoroacetone (TIFA) and NADPH oxidase inhibitor diphenyleneiodonium (DPI) for 1 h, and stimulated with different concentrations of NE for 24 h, before the level of IL-6 protein was detected by ELISA. RESULTS The expression of IL-6 mRNA and protein increased with the concentration NE 0.01-10 μmol · L-1 and incubation time. IL-6 mRNA and protein levels in macrophages were 2.62 and 4.47-fold those in cell control group when treated with NE 1.0μmol·L-1 for 24 h. Meanwhile, as the concentration of NE increased, the generation of ROS was 1.87, 2.56, 2.91 and 5.36-fold that of cell control group (P<0.01). NAC 10 mmol · L-1 and DPI 10 μmol · L-1 significantly antagonized the effect of NE on IL-6 expression, but TIFA had no effect. CONCLUSION NE upregulates IL-6 expression, which may contribute to the formation and develop?ment of atherosclerosis via ROS mediated by NADPH oxidase in macrophages.

Objective In order to study the relationship between the platelet activation sign:P-selectin(GMP 140 ) expression and human IgA nephropathy.Methods Expression of platelet membrane glucoprotein Ⅱb/Ⅲa(GP Ⅱb ,GP Ⅲa ) in blood for IgA nephropathy patients(n=46) was investigated by flow cytometry methods.Results In IgA nephropathy the up-regulated GMP 140 expression in blood was significantly higher than that in normal humans.Conclusions GMP 140 might play an important role in pathogenesis of IgA nephropahty,and the level of GMP 140 in blood might predict renal outcome in IgA nephropathy.
