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 investigate the compliance of ketogenic diet in children with refractory epilepsy and its correlation with the curative effect, and to provide support and basis for the implementation and improvement of the long-term management of ketogenic diet in this patient population. MethodsA total of 106 children and their families who were followed up on ketogenic diet in the Department of Pediatrics of Fudan University from March 2019 to January 2022 in the Department of Ketogenic Multidisciplinary Treatment (MDT) were selected by convenience sampling method. General data questionnaire and ketogenic compliance questionnaire were used for investigation and follow-up. ResultsThe mean compliance of ketogenic diet in refractory epilepsy children was (13.27±3.68). The compliance scores of ketogenic children with different therapeutic effects and cognitive functions were significantly different. The compliance score was significantly correlated with the therapeutic effect and cognitive level, that is, the higher the therapeutic effect of ketogenic diet in children with higher compliance score, the better the cognitive improvement. ConclusionThe compliance of ketogenic diet in children with refractory epilepsy needs to be further improved. Improving the compliance of ketogenic diet is of great significance for the efficacy of ketogenic diet. Medical staff should actively develop the corresponding intervention program and follow-up management mode to further improve the treatment compliance of children's families, improve the treatment effect and improve the quality of life of children's families.
Objective To collect and analyze the qualitative studies on patients’ compliance with hypertension management in the community, and to summarize the factors influencing the compliance from the view of patients. Methods Eleven electronic databases and search strategies and words were determined through discussion by experts and the review group. After the selection and critical appraisal of the retrieved studies were performed by two reviewers independently, meta-summary was employed for the results of qualitative studies. Results Five studies were included. The results showed some factors had great impact on the compliance of patients, including patients’ knowledge of hypertension and its treatment, doctor-patient relationship, patients’ financial status, social support, designing of treatment plans, and patients’ individual conditions. Conclusion To improve doctors’ technical competence, building good doctor-patient relationship, strengthening patients’ individualized health education, formulating the proper treatment plan, and making good use of the social support system would promote the compliance with hypertension management in the community.
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.
ObjectiveTo investigate the effect of medical counseling games on ketogenic diet therapy for drug-resistant epilepsy children. MethodsA total of 98 children with drug-resistant epilepsy admitted to the neurology ward of Shenzhen Children's Hospital from January 2023 to June 2024 who were treated with ketogenic diet for the first time were selected as the study objects by random number table method, and were divided into observation group (n=49) and control group (n=49). The control group received the traditional multidisciplinary team health education mode, while the observation group received the ketogenic diet treatment based on the multidisciplinary team health education mode and participated in the customized medical counseling games intervention. The time of children reaching ketosis, the knowledge level of ketogenic diet caregivers and the retention rate of children on ketogenic diet were compared between the two groups. ResultsThe time of ketosis in observation group was earlier than that in control group (P<0.05). The knowledge level of the main caregivers of ketogenic diet and the retention rate of children with ketogenic diet at 3 months and 6 months in observation group were higher than those in control group (P<0.05). ConclusionThe use of medical counseling games in the ketogenic diet for medically refractory epilepsy is an effective therapeutic strategy that facilitates the early attainment of ketosis in children with medically refractory epilepsy, improves the knowledge of caregivers on the ketogenic diet, improves retention of children on the ketogenic diet, and serves to optimize the effectiveness of clinical outcomes, which may contribute to the quality of life of children with medically refractory epilepsy.
ObjectiveTo compare the investigation results of compliance and accuracy of hand hygiene in medical staff achieved by Hospital Infection Management Department and Department Infection Management Teams, and analyze the reasons for differences of the results and take measures to improve the investigation ability of hand hygiene in hospitals. MethodsWe statistically analyzed the results of compliance and accuracy of hand hygiene from January to December 2013 investigated by the infection management department and 25 infection management teams. Both the hospital and departments used "WHO Standard Observation Form". Single-blind method was used to observe the implementation of hand hygiene in medical staff. ResultsThe hospital infection management department investigation showed that hand hygiene compliance and accuracy were 64.97% and 87.78%, respectively, while the investigation by infection management teams showed that hand hygiene compliance and accuracy were 90.54% and 93.37%, respectively. The differences between the investigation results of two-level organizations were statistically significant (χ2=286.2, P<0.001; χ2=532.6, P<0.001). ConclusionWe should take measures to enforce the training of hand hygiene implementation and the observation method, and improve the guidance and assessment, promote investigators' working responsibility and observation ability, so that the survey data can accurately reflect the actual situation to urge medical staff to form good hand hygiene habits.
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 investigate the efficacy of follow-up continuous nursing intervention on the self-management ability and medication compliance of patients undergoing maintenance hemodialysis. MethodsBetween June and December 2013, 157 maintenance hemodialysis patients were randomly divided into control group (n=76) and study group (n=81). The control group was given conventional nursing, while the study group received continuous nursing intervention program as well as conventional nursing. Six months later, the self-management ability and medication compliance of the patients were assessed by using self-made Patient Self-management Scale and Morisky Medication Compliance Scale. ResultsSix months later, self-management ability in patients of the study group was significantly better than that in the control group (P<0.05). Medication compliance rate in the study group reached a highest of 45.7%, while it was only 18.4% in the control group, and the difference between the two groups was significant (χ2=13.283, P<0.001). ConclusionFollow-up continuous nursing intervention can obviously improve maintenance hemodialysis patients' ability of self management and compliance behavior, so as to improve the quality of life of these patients.
ObjectiveTo discuss the impact of health education for the patients with decompensated cirrhosis and their family members on patients' family life quality, psychological conditions, medication compliance, and re-admission rates. MethodsWe selected 100 decompensated cirrhosis patients between December 2012 and December 2013, and randomized them into two groups with 50 patients in each. One week prior to discharge, we conducted a comprehensive nursing assessment for the patients and developed hospital care regimen. Patients were followed up after discharge for six months. The control group underwent routine health education and extended care, while the experimental group had an addition of health education and extended care intervention on their family members. ResultsAnxiety and depression were alleviated in both the two groups. The psychological conditions of patients in the experimental group were significantly better than the control group (P<0.01). The total scores of quality of life was significantly different compared with the scores before intervention (P<0.01). Medication compliance improved more significantly in the experimental group after intervention (P<0.05). Re-admission rates decreased more significantly in the experimental group than the control group (P<0.01). ConclusionHealth education and extended care intervention for patients and their family members can improve patients' psychological conditions, promote medication compliance, reduce readmission rates, and improve patients' quality of family life.
ObjectiveTo explore the effect of respiratory support in Community Respiratory Support Center on patients with chronic obstructive pulmonary disease (COPD) in stable phase. MethodsSixty-four GOLD gradeⅢpatients with stable COPD over age of 55 years were randomly divided into two groups.A respiratory support group received respiratory support in Community Respiratory Support Center, including health education, long-term oxygen therapy (LTOT), long-term ambroxol for atomization, long-term budesonide and formoterol for inhalation.A control group were prescribed budesonide and formoterol for inhalation when recruited, informed LTOT and long-term ambroxol for atomization at home, and follow-up visits to clinic every month. ResultsAfter 24 months of treatment in the respiratory support group, SpO2, PaO2, FEV1%pred, 6MWD, BMI, and ALB increased, mMRC, CAT, Hb, PaCO2 decreased (P < 0.05).While in the control group, FEV1%pred decreased, mMRC and CAT increased (P < 0.05), other indexes did not change significantly (P > 0.05).The times of acute exacerbation and hospitalization of the respiratory support group was less than that in the control group(P < 0.05). ConclusionsEstablishing Community Respiratory Support Center will benefit patients with stable COPD correct hypoxemia, slow the deterioration of lung function, improve the nutritional status of patients, and can also increase patients compliance to treatment.
