ObjectiveTo investigate predictive value of matrix metalloproteinase-9 (MMP-9) and Interleukin-6 (IL-6) combined with cervical length in premature delivery.MethodsPlasma samples of 62 pregnant women were detected in this study.Samples were divided into three groups based on pregnancy outcomes.MMP-9 and IL-6 values were determined by ELISA.Cervical length was measured by transvagihal sonography.ResultsThe level of MMP-9 of the pregnant women in the premature delivery group was significantly higher than that of continuous pregnant group and that of normal pregnant women [(47.24 ±6.41) ng/ml,(523.24 ± 62.35) pg/ml vs (20.39 ±7.23 )ng/ml,(219.29 ± 80.23)pg/ml,(32.18 ±5.16)ng/ml,(406.18 ±71.52) pg/ml,P ＜0.01].The level of MMP-9 and IL-6 of the pregnant women in the continuous pregnant group was significantly higher than that of normal pregnant women [(32.18 ±5.16)ng/ml,(406.18 ±71.52) pg/ml vs (20.39 ±7.32) ng/ml,(219.29 ± 80.23) pg/ml,P ＜0.01].Cervical length of the pregnant women in the premature delivery group was significantly shorter than that of normal pregnant women and that of continuous pregnant group [( 15.62 ± 2.31 )mm vs ( 31.05 ± 1.48 )mm,(26.14 ±3.12)mm,P ＜0.01].ConclusionsDetection of level of MMP-9 and IL-6 combined with measurement of cervical length can be used as predicting index of premature delivery.

Objective To explore the clinical effect of health education and psychological nursing intervention on the prognosis of patients with postpartum depression. Methods Ninety cases of postpartum depression in our hospital from March 2012 to March 2014, were randomly divided into the control group and the observation group, 45 cases in each group. The patients in the control group were given routine nursing, the patients in the observation group received health education and psychological intervention on the basis of the control group. The anxiety and depression scores change, medication adherence and quality of life in the two groups were observed and compared. Results The scores of SDS and SAS in the observation group were significantly lower than those in the control group (P<0.05) . The medication adherence and quality of life score 3 months and 6 months after discharge in the observation group were significantly higher than those of control group (P<0.05) . Conclusion Health education and psychological intervention has positive effect on the prognosis of postpartum depression patients, and can effectively improve the patient's medication compliance and quality of life, it's one of the effective measures for the prevention and treatment of postpartum depression.

Objective To explore targeted time management to shorten the time from arriving hospital to thrombolysis ( DNT ) . Methods A total of 42 suspected acute ischemic stroke ( AIS ) patients were underwent the targeted time management from pre-hospital until emergency thrombolysis while other 24 cases from 120 to hospital started from the time arriving Emergency Department. The complete rate of targeted time management and DNT compared with before management. Results In the control group, the hospital received 42 pre-hospital patients suspected with AIS in 3 hrs, and completed all targets 31 cases with pass rate of 73. 8%; the experimental group acquired 38 cases and achieved targets 35 cases with pass rate of 92. 1% (χ2 =4. 625,P<0. 05). In the experimental group, the pass rate of pre-hospital Emergency Department, CT detection, thrombolysis preparation were 100% (38/38), 94. 7% (18/19), 94. 7%(18/19) higher than 61. 9% (26/42), 55. 6% (10/18), 58. 8% (10/17) (χ2 =18. 095,5. 727,4. 779;P <0. 05). A total of 17 cases underwent thrombolysis with DNT of ( 68. 65 ± 23. 75 ) min while 19 cases in the experimental group with DNT of (35.50±2.98)min(Z=5.106,P<0.01),and4casescomingfrom120withDNTof(46.40±5.68) min (Z= -4. 092,P <0. 05). Conclusions To utilize pre-hospital time reasonable, we make the thrombolysis process early, regulate the process, manage each segment time targeted, find out and improve the reasons for overdue segment, make clear individual responsibility, which can shorten the DNT and be benefit patients.

Objective:To provide evidence-based recommendations for the prevention and management of lower limb ischemia in veno-arterial extracorporeal membrane oxygenation (VA-ECMO) patients during treatment according to search, evaluate, and summarize the best evidence on the prevention and management of lower limb ischemia in patients with VA-ECMO.Methods:Based on the PIPOST framework (population, intervention, professional, outcome, setting, and type of evidence), an evidence-based question was formulated. A systematic search was conducted according to the "6S" evidence pyramid model in both domestic and international databases, as well as professional association websites, for all evidence related to the prevention and management of lower limb ischemia in VA-ECMO patients (aged ≥18 years). The types of evidence included clinical decisions, guidelines, expert consensus, systematic reviews, evidence summaries, and original studies. The search was conducted from the construction of the databases to February 2024. Two researchers independently conducted a literature quality evaluation, extracted and summarized evidence from the studies that met the quality criteria.Results:A total of 13 articles were included, consisting of 3 clinical decisions, 3 guidelines, 3 expert consensus, 3 systematic reviews, and 1 randomized controlled trial. A total of 18 pieces of evidence in 7 dimensions were summarized, including risk factors of VA-ECMO lower limb ischemia, evaluation before catheterization, evaluation and monitoring during treatment, prevention of lower limb ischemia, treatment of lower limb ischemia, management of distal perfusion catheter (DPC), and monitoring after VA-ECMO weaning.Conclusion:This evidence summary provides evidence-based recommendations for the prevention and management of lower limb ischemia in VA-ECMO patients, aiming to assist clinical healthcare professionals in developing tailored strategies for the prevention and management of lower limb ischemia based on during VA-ECMO support.
