This paper introduces the present situation of condition monitoring of medical devices, states main methods of condition monitoring and puts forward the application strategies in hospitals briefly.

Objective To study NF-κB ODN decoy-treated DC on type Ⅱ collagen- induced arthritis(CIA) serum IFN-γ,IL-10 and anti B Ⅱ C antibody and its mechanism.Methods Type Ⅱ collagen induced arthritic rats was established.NF-κB decoy-treated DC loaded with B Ⅱ C from rat spleen were injected to CIA rats via the tail vein at 5 days after the initial immunization.The rats were divided into control group,CIA model group and B Ⅱ C-decoy-DC experimental groups.Forty-two days after the initial immunization,the arthritis scores were determined,the ankle pathology examination were performed and the levels of the serum IFN-γ,IL-10,anti-Ⅱ collagen antibody were determined using ELISA.Results The levels of IFN-γ and anti-B Ⅱ C antibody in serum of CIA model group were increased significantly and IL-10 was decreased significantly (P＜0.05,vs control group).After received with NF-κB ODN decoy inducing DC loaded with B Ⅱ C,the levels of IFN-γ and anti-B Ⅱ C antibody in serum of B Ⅱ C-decoy-DC experimental groups were decreased significantly and IL-10 was increased significantly (P＜0.05,vs CIA model group).Conclusion NF-κB decoy-treated DC loaded with B Ⅱ C had significantly inhibited IFN-γ and anti-B Ⅱ C antibody production and promoted increased levels of IL-10,and had a good curative effect on the treatment of rheumatoid arthritis.

Objective Acrysof IQ Restor multifocal toric intraocular lens ( IOL) is a new product , which allows a single sur-gical procedure for presbyopia correction and corneal astigmatism management .This study was to evaluate the early clinical effects of phacoemulsification cataract surgery with implantation of a diffractive multifocal toric IOL . Methods We retrospectively analyzed 7 cases (9 eyes) of corneal astigmatism ≥1.0 diopter (D) treated by phacoemulsification with implantation of an Acrysof IQ Restor toric IOL.The patients were followed up for 3 months for observation of uncorrected distance visual acuity ( UDVA) , best corrected distance visual acuity ( CDVA) , uncorrected near visual acuity ( UNVA ) , best corrected near visual acuity ( CNVA ) , spherical equivalent (SE) refraction, focal depth, residual astigmatism, rotational stability of the IOL, contrast sensitivity (CS), and spectacle independ-ence preoperatively and at 1 week, 1 month, and 3 months after operation . Results At 3 months after surgery , the UDVA ( log-MAR), CDVA, UNVA, and CNVA were 0.07 ±0.10, 0.02 ±0.11, 0.12 ±0.06, and 0.08 ±0.07, respectively, with an SE re-fraction within ±0.50 D of the attempted spherical correction in 8 eyes (88.9%) and a focal depth of (5.32 ±1.78) D.The residual astigmatism at 3 months was significantly reduced as compared with the baseline ([0.25 ±0.28] vs [1.55 ±0.39] D, P<0.05), but showed no statistically significant differences from the preoperative an-ticipated residual astigmatism (P>0.05).At 3 months, the mean IOL axis rotation was (3.11 ±1.61)°and CS was remarkably im-proved ( P<0 .05 ) , while CS with or without glare was not significantly different from that at 1 month at all spatial frequencies ( P>0.05) except at 18.0 cpd (P<0.05). Conclusion Implantation of the Acrysof IQ Restor multifocal toric IOL provides excellent overall quality of vision, spectacle independence, visual quality, and rotational stability for patients with cataract and corneal astigmatism.

Objective To investigate the correlation between admission hyperglycemia and clinical prognosis in elderly patients with community-acquired pneumonia.Methods Based on the electrical medical record (EMR),information of the patients with pneumonia was retrospectively collected and the necessary data were prepared and arranged.Based on clinical outcomes,demographic characteristics and clinical indicators were compared between groups in order to screen potential variables affecting clinical outcomes.Then,the random blood glucose level 8.6 mmol/L was considered to be the cutoff point for grouping patients,with clinical outcomes as outcome variables,random blood glucose levels as grouping variables,propensity score value analysis method was applied along with the ratio of 1:1 nearest neighbor matching method to generate paired samples in order to assess the impact of blood glucose level on mortality rate;With hospitalization time serving as time variable,survive analysis method was used to analyze COX proportional model.Results Five hundred and fifty-eight patients were enrolled in the analysis,197 patients of which were recorded dead during hospitalization (the dead group).After the correction of demographic characteristics,past medical history and blood test indexes,white blood cells,C reactive protein,random blood glucose at admission and triglyceride levels were regarded as potential factors for the deaths of patients (P<0.05).However,the propensity score analysis method suggested that there was no significant difference between the blood glucose levels and mortality.The survival analysis showed that the mortality in the high blood glucose group was higher than that in the normal blood glucose group (HR=1.68,95%CI(1.22,2.31)).Conclusion Admission hyperglycemia is an important indicator of adverse prognosis in elderly patients with pneumonia.It may be of significance for screening and identifying high-risk patients.

This study delves into the pivotal factors influencing the consensus process within traditional Chinese medicine guideline development, with the objective of augmenting the quality of this process through methodological recommendations aimed at elevating standardization.
