ABSTRACT
Objective:To analyze the relationship and clinical value between serum matrix metalloproteinases-3 (MMP-3) and rheumatoid arthritis (RA).Methods:By using retrospective study to collect 123 patients with RA diagnosed in our hospital from January 2019 to January 2020 as the RA group. Among the patients, there are 25 males and 98 females, the median age is 60 years old. During the same term, 53 healthy people were selected as the control group, with 12 males and 41 females, the median age is 55 years old. MMP-3, erythrocyte sedimentation rate (ESR), high sensitivity C-reactive protein (hs-CRP), rheumatoid facotrs (RF), anti-cyclocitrulline factor (ACCP) in peripheral blood of all subjects were detected. Disease activity score of 28 joints (DAS28) were collected. This research used T test, Spearman correlation analysis and receiver operating characteristic curve (ROC curve) to analyze the relationship between MMP-3 and other clinical biochemical indices, and the efficacy of MMP-3 in the diagnosis of RA.Results:Compared with the control group (26.30±14.83)ng/ml, the levels of serum MMP-3 in the RA group (79.71±123.54) ng/ml had significantly increased ( t=-4.95, P<0.001). The serum concentration of MMP-3 in RA patients was significantly correlated with ESR, hs-CRP and DAS28 ( r value were 0.521, 0.372, 0.405 respectively, P<0.001). The area under the curve (AUC) of MMP-3 to diagnose RA was 0.765, and the sensitivity was 64.44%, and the specificity was 75.76%, cut-off of MMP-3 were 32.50 ng/ml. Conclusions:The levels of serum MMP-3 in the RA group had significantly increased. MMP-3 and the disease activity were highly correlated. MMP-3 can be used as an indicator of RA disease activity, also can significantly improve the diagnostic efficacy, treatment and warning of early RA.
ABSTRACT
Intellectual property in medical institutions has been getting more attention in research activity.Large general hospitals have made significant achievements in intellectual property,and the management of intellectual property right has also gradually become the norm.This article discussed the possibility to carry out the intellectual property management in the primary health care sector,based on their current status and characteristics,proposed an evaluation system which suitable for the primary health care sector.We described the structure and method of this system,explored a standardized intellectual property management process used in primary health care institutions.
ABSTRACT
Objective To investigate the present situation and to analyze related factors of nursing practice environment among 22 public hospitals in Shanghai area.Methods We investigated 1 600 nurses from the 22 hospitals with general information questionnaire and the Chinese version of Practice Environment Scale,and also analyzed related factors by single and multiple factor analysis.Results 1 582questionnaires were taken back.49％ were dissatisfied with their working environment,and 28.1％ were evaluated to have nice practice conditions.Nurse concerned with workforce management and adequate resources were widespread.Logistic analysis indicated that hospital's level,the nurse's age,educational background and seniority were main factors influencing nurses' satisfaction.Nurse work in tertiary hospitals reported lower satisfaction.Conclusions More attention should be paid on improving nursing practice environment.
ABSTRACT
Objective To investigate the influence of irbesartan taken before bedtime on morning blood pressure surge and urine microalbuminuria in elderly patients with essential hypertension. Methods Ninety-two patients with uncontrolled hypertension were recruited in this study and their 24-hour ambulatory blood pressure monitoring profiles were collected for analysis. After irbesartan taken before bedtime, its influence on general blood pressure, morning blood pressure surge and urine microalbuminuria was observed. Results Before irbesartan treatment,the average 24-hour ambulatory blood pressure was(140.1 ± 12. 7)mm Hg, the morning blood pressure surge was (45.6 ± 10.8) mm Hg, urine microalbuminuria level was (58.6 ± 3.7) mg/L. After irbesartan treatment,the average 24-hour ambulatory blood pressure decreased to (129. 5 t 11.8) mm Hg (t = 3.18, P ＜ 0.05), the morning blood pressure surge decreased to(14. 2 ±4. 1)mm Hg(t =5.74,P ＜0.01) ,urine microalbuminuria level decreased to(31.7±3.1)mg/L(t =5.24,P＜0.01).Conclusions Irbesartan can effectively reduce the peak morning blood pressure,improve achievement ratio of blood pressure control, decrease urine microalbuminuria level in elderly patients essential hypertension.
