Objective To evaluate which is better method zymogen or low temperature frozen in removing vascular endothelial cell so as to lay a foundation for creating a kind of brace which is not to be rejected and the same as own blood vessel. Methods Fresh and not damaged umbilical blood vessel was collected from natural labour women, human umbilical blood vessel was remove carefully from normal foetus, then was put into disinfectant at 37℃ for 24 hours. They were divided into 3 groups:normal group(NG),zymogen group(ZG) and low temperature frozen group(LG). ZG: 0.1% collagenⅡ enzyme was addedin umbilical blood vessel and closed the both sides and the vascular endothelialcell was removed in 37℃ water. LG:Umbilical blood vessel was put into liquidnitrogen for 24 hours after frozened step by step, and then it was put into 37℃ water for 30-60 s and the vascular endothelial cells were washed away by normal saline. NG:Umbilical blood vessel was kept into 4℃ Kerb’s liquid. The bacteria were culturedin each group. The samples were stained by HE,elastic fiber and collagen fiberwere observed by light and scanning electron microscope. The difference of compliance was compared. Human leukocyte antigen ABC(HLA-ABC) and HLA-DR were observed by immunohistochemical method and the expression of antigen of umbilical blood vessel was analysed. Results In LG, umbilical vascular endothelial cells were removed completely; artery showed vertical smooth muscle and vein showed elastic membrane. InZG, umbilical vascular endothelial cells were removed completely after 20 minutes;artery showed vertical smooth muscle cells and vein showed lower endothelial layer. The vascular compliance in LG was higher than that in NG, and the latter was also higher than that in ZG,but showing no significant differences (Pgt;0.05). The compliance of umbilical vein was 2-3 times as much asthat of umbilical artery.The expression of HLA-ABC and HLA-DR in LG andZG were lower than that in NG, showing significant differences (Plt;0.01). Conclusion Low temperature frozen methodand zymogen method(0.1% collagen Ⅱ enzyme for 20 min) can remove vascular endothelial cells of human umbilical blood vessel completely.Low temperature frozenmethod was better than zymogen method.
OBJECTIVE: To explore the relationship between the properties of compliance and the change of structure of components in anastomosed arteries. METHODS: The arterial pressure and diameter of femoral arteries of dogs were measured in vivo before and after arterial anastomosis in different time intervals to deduce the arterial compliance. The anastomosed arteries were removed and evaluated through light microscopic examination and various staining methods, the relative contents of elastin, collagen and smooth muscles were measured through image analysis system. RESULTS: The compliance of arteries was gradually decreased after anastomosis with peak-time on the 14th day. The content of elastin at different time had no significant difference, while the content of collagen increased gradually, the ratio of them was increased. CONCLUSION: The property of compliance of anastomosed arteries is closely related to the contents of the structural components.
Objective To study the special traits of primiparae’s compliance with labor analgesia, so as to offer individualized analgesia solutions during spontaneous labor. Methods The uniparous primiparae with cephalic presentation between gestational weeks 38 and 40 were divided into two groups based on their educational background (college education or above, and high school education or below), each group with 20 cases. The demographical statistics of the two groups including their State-Trait Anxiety Inventory (STAI) grading, PCA results, and delivery situation were recorded and analyzed. Results Differences in age, height, and weight were not statisticallysignificant (Pgt;0.05); differences in T-AI were not statistically significant (Pgt;0.05); differences in S-AI were statistically significant (Plt;0.05); differences in anxiety and numbers of adding anesthetics were not statistically significant (Pgt;0.05); differences in failure to tolerate labor pains and requiring caesarean section were statistically significant (Plt;0.05). Conclusion Primiparae with higher educational degree tend to have higher S-AI grading and perform poorly in compliance with labor analgesia.
ObjectiveTo explore the effect of programmed family nursing intervention on medication compliance in hypertensive patients. MethodsA total of 160 patients with hypertension treated between August 2012 and July 2013 in our hospital were chosen to be our study subjects. They were randomly divided into two groups:control group (n=80) and trial group (n=80). Patients in the control group were given routine nursing intervention for six months, while those in the trial group received six-month programmed family nursing intervention. Then, we compared the effect of blood pressure control and medication compliance between the two groups. ResultsThe effect of blood pressure control and medication compliance in the trial group after the intervention was better than that in the control group, and the difference was statistically significant (P<0.05). ConclusionThe programmed family nursing intervention is better than the routine nursing intervention in terms of effect of blood pressure control and patients' medication compliance, and it is an effective nursing method for hypertensive patients.
ObjectiveTo explore the influence factors of therapeutic compliance and emotional expression of first-degree relatives in acute schizophrenic patients with psychotic symptoms. MethodsThe Brief Psychiatric Rating Scale (BPRS) was used to measure the severity of psychotic symptoms in sixty schizophrenic patients from June to September 2014 in West China Hospital and the Toronto Alexithymia Scale (TAS) was used to survey the emotional expression in their family members. The homemade treatment adherence scale was used to survey the treatment adherence in patients for one week. ResultsThere was a poor therapeutic compliance in nineteen patients with acute schizophrenia (32%) and the other 41(68%) had good therapeutic compliance; the relatives of schizophrenic patients had high TAS scores (male: 67.61±10.03; female: 69.68±11.46) than the normal models did (P ＜ 0.05) . The differences between the patients with different therapeutic compliance in BPRS total score, reactivator, hostile and suspicion factor (P ＜ 0.05) . The therapeutic compliance was related to the severity of the psychotic symptoms (P ＜ 0.05) . Conclusions There is a bad emotional expression in the relatives of acute schizophrenic patients. The psychotic symptoms can influence the therapeutic compliance. The milder the psychotic symptoms, the better the therapeutic dependence.
Objective To investigate the effect of a real-time compliance dashboard to help reduce ventilator-associated pneumonia ( VAP) with ventilator bundle. Methods 240 patients who were admitted into the intensive care unit ( ICU) of Shougang Hospital of Peking University and had received mechanical ventilation ( MV) for over 48 hours, between January 2010 and November 2011, were studied prospectively. The patients were divided into two groups by random number table, ie. a dashboard group ( n = 120) with implementation of a real-time compliance dashboard to help reduce VAP with ventilator bundle, and a control group ( n=120) with implementation of usually routine order to help reduce VAP with ventilator bundle. The success rate of ventilator bundle implementation, incidence of VAP, duration of MV, duration within ICU, mortality within 28 days, cost within ICU were compared between two groups. Results Compared with the control group, the success rate of ventilator bundle implementation obviously increased ( 81.6% vs. 52.5%) , incidence of VAP ( 14. 5/1000 days of MV vs. 36.2 /1000 days of MV) , duration of MV [ 5( 4,7) days vs. 8( 6,11) days] , duration within ICU [ 8( 6,12) days vs. 13( 8,16) days] , mortality of 28 days ( 12.6% vs. 28.6% ) , and cost within ICU ( 36,437 vs. 58,942) in the dashboard group obviously reduced ( Plt;0.05) . Conclusions Implementation of a real time compliance dashboard to help reduce VAP with ventilator bundle can obviously improve medical personnel compliance and reduce incidence of VAP, duration of MV, duration within ICU, mortality and cost in ICU than those of routine medical order to help reduce VAP with ventilator bundle.
【Abstract】 Objective To investigate the effects of respiratory syncytial virus ( RSV) infection on the dynamic changes of airway hyperresponsiveness ( AHR) in ovalbumin ( OVA) -induced asthma in mice.Methods 60 BALB/c female mice were randomly divided into PBS control group ( A group, n = 6) , OVA group, OVA/RSV group, dexamethasone group ( D group, n =6) . Kinetics of AHR of OVA group mice was carried out on day 21, 25, 29 and 33 ( B1, B2, B3, B4 groups, n =6) , and the same with the OVA /RSV group( C1, C2, C3, C4 groups, n = 6 ) . The mouse asthma model was established by OVA-sensitization of intraperitoneal injection and repeated inhalation of OVA while the mice in OVA/RSV group were treated with combined intranasal inoculation with RSV ( 1. 0 ×106 pfu/mL in 50 μL) . Airway resistance of expiringphase ( RL ) and compliance of throax and lung ( CTL ) with different doses of acetylcholine ( Ach) were measured. Lung tissue sections were stained with hematoxylin and eosin ( HE) and periodic acid-Schiff ( PAS) for general morphology. Results Compared with B1 group, RL increased and CTL decreased in C1 group when Ach dose is above 5 g/L ( P lt; 0. 05, respectively) , and the effects prolonged ( 6 d, 10 d after challenge with OVA, respectively) much more than B1 group ( 2 d after challenge with OVA) . Compared with C1 group, RL decreased and CTL increased in D group and the infiltration of inflammatory cells was obviously alleviated in C1 group after treatment with dexamethasone. Conclusions Airway hyperresponsiveness increases obviously in OVA-sensitized and RSV-infected mice. The prolonged increase inRL and decrease in CTL ( 6 d, 10 d, respectively) may imply that RSV infection aggravates airway inflammation. The small airway inflammation may play a critical role in the persistence of airway hyperresponsiveness.
Objective To explore the compliance improvement of rehabilitation exercise for patients after spine surgery. Methods Forty-nine in-patients who underwent spinal surgery between June 1st and July 14th 2016 were selected as the control group and 50 in-patients who underwent spinal surgery between July 15th and August 30th 2016 were selected as the trial group. The control group received conventional nursing for rehabilitation exercise, and the tiral group adopted a series of quality improvement measures for rehabilitation exercise. The compliance of functional exercise, the accuracy of patients’ exercise and the satisfaction with health education of the patients were compared between the two groups. Results The functional exercise compliance in the trial group (complete compliance in 45 cases, partial compliance in 4 cases, non-compliance in 1 case) was higher than that in the control group (complete compliance in 9 cases, partial compliance in 34 cases, non-compliance in 6 cases) with a statistical difference (Z=–6.910, P<0.001). The functional exercise accuracy rate of patients was higher in the trial group [84.00%(168/200)] than that in the control group [53.06% (104/196)] with a statistical difference (χ2=44.060, P<0.001). The patients’ satisfaction with health education in the trial group (4.64±0.49) was higher than that in the control group (4.20±0.89) with a statistical difference (t=3.084, P=0.003). Conclusion The implementation of nursing quality improvement intervention can improve the compliance and accuracy rate of rehabilitation functional exercise of patients undergoing spinal surgery, and improve the satisfaction of patients, which is worth promoting.
This study was performed on canine femoral veins which were interpositionally implanted into the femoral arteries and the investigation was in terms of zero-stress state, compliance and hemodynamic assessment. The results revealed that the vein grafts had the similar characteristics of compliance with the normal veins. Using Doppler ultrasonography to monitor the blood flow velocity through the vein grafts, the hemodynamic parameters such as pulsatility index (PI) and blood flow volume were evaluated consecutively within one month after the operations .No significant differences were found between these parameters at different time points. It was suggested that autogenous vein graft had an adaptive course when operating in an arterial hemodynamic circumstances and It’s mechanical changes did not bear upon the hemodynamics through the vein graft.
ObjectiveTo analyze the status quo, problems and weak points of cleaning compliance in the Intensive Care Unit (ICU), and assess the intervention effects by evaluating the object surface cleaning quality in the ICU. MethodsBetween September 1st and December 1st, 2014, fluorescence marker was used to mark the surfaces of medical instruments and objects in the ward which were supposed to be cleaned by the nursing and cleaning staff. The assessment of cleaning compliance was performed through observing the residual fluorescence. Then, targeted intervention was carried out for situations with a low cleaning compliance. ResultsBefore the intervention, the thorough cleaning rates of medical instruments in the Comprehensive ICU, Neurological ICU (NICU), and Chest ICU were respectively 43.3%, 31.4%, and 23.8%, and the thorough surface cleaning rates for those units in order were 67.1%, 60.5%, and 48.4%, respectively. After the first intervention, the cleaning rate of medical instruments in the Comprehensive ICU was 47.1%, which had no significant change (P=0.345), but the rate in the NICU and Chest ICU reached respectively 65.3% and 35.1%, which was significantly improved (P<0.05). The object surface cleaning rates were 73.3% and 58.1% in the Comprehensive ICU and Chest ICU after the first intervention, and there was no significant difference compared with those before the intervention (P>0.05), but the object surface cleaning rate in the NICU was significantly improved to 85.5% (P<0.05). After the second intervention, the medical equipment cleaning rates were 66.9%, 83.3%, and 57.4%, respectively for those three units, and compared with those before intervention, all the three were significantly improved (P<0.05). The object surface cleaning rates for NICU and Chest ICU were significantly raised to 85.6% and 84.2% (P<0.05), while it was 65.7% in the Comprehensive ICU and was not significantly improved (P=0.767). ConclusionObservation and supervision through a feedback system can raise the cleaning compliance, which is helpful in controlling and preventing nosocomial infection.
