ABSTRACT
Objective:To analyze the risk factors associated with hemorrhagic complications at the puncture site after femoral artery access cerebrovascular interventions and construct a bleeding risk scale.Methods:Two hundred and fifteen patients who underwent femoral artery puncture interventions in the neurointerventional department ward of the First Affiliated Hospital of Zhengzhou University from April to October 2020 were selected for the study, including 60 cases in the complication group and 155 cases in the control group. The patients′ general data, interventional procedure-related data and laboratory tests were analyzed univariately and then incorporated into a binary multi-factor logistic regression analysis to determine independent risk factors, and a bleeding risk scale was constructed according to the regression model.Results:Compared with the control group, there was a statistically significant increase in the incidence of women, diabetes mellitus, use of glucose-lowering drugs, proportion of (anticoagulant/antiplatelet drugs) use and irritability in the complication group ( χ2 values were 4.94-15.81, all P<0.05); age, BMI, HbA1c, prothrombin time activity, and sheath size and operative time were higher than those of the control group, and prothrombin time and creatinine values were lower than those of the control group, with statistically significant differences ( t values of -6.25 to 2.80, respectively, all P<0.05). Multifactorial logistic regression analysis showed that gender ( OR=0.09, 95% CI 0.025-0.302), BMI ( OR=1.736, 95% CI 1.462-2.115), HbA1c ( OR=1.775, 95% CI 1.107-2.845), and use of anticoagulant/antiplatelet drugs ( OR= 0.082, 95% CI 0.015- 0.448) and time to surgery ( OR=1.031, 95% CI 1.012-1.052) were independent risk factors for bleeding complications. In the risk scale: the total score was -3 to 13, and risk existed for a score ≥5. The sensitivity of this scale was 83.3%, the specificity was 92.3%, and the area under the ROC curve was 0.878 ( P<0.001, 95% CI 0.818 to 0.938). Conclusions:Female, high BMI, high HbA1c, anticoagulant/antiplatelet drug use, and long procedure time can increase the risk of bleeding complications at the femoral artery puncture. The predictive model has good predictive performance and can be extended for use.
ABSTRACT
Objective:To explore the effect of WeChat mini program in immunotherapy management of pediatric patients with combined allergic rhinitis and asthma syndrome (CARAS).Methods:Using the convenient sampling method, 101 children with CARAS who received sublingual immunotherapy in the First Affiliated Hospital of Zhengzhou University from January 2019 to January 2020 were selected as the research objects. The standardized management team of immunotherapy clinic was established. The newly developed specific immunotherapy Wechat applet was used to establish a new model of nurse-patient interaction and communication. The disease knowledge was regularly pushed, medication reminder, nurse telephone intervention and other standardized management were delivered through the Wechat applet to implement continuous nursing for children. The effects of this management model on medication compliance, rhinitis symptoms and asthma control were analyzed.Results:A total of 101 children were included in this study, 3 cases were lost to follow-up, and a total of 98 cases completed the study. After 12 months of intervention, the drug possession score of dust mite drops increased from (83.43±3.68) to (91.78±3.71), the symptom score of allergic rhinitis decreased from (5.83±1.32) to (1.94±0.98), and the score of asthma test questionnaire increased from (18.12±3.99) to (24.97±3.09), the proportion of children with complete control of asthma increased from 48.0% to 90.8%, and the proportion of children without control of asthma decreased from 10.2% to 1.0% (all P<0.05). Conclusion:The immunotherapy management of pediatric patients with combined allergic rhinitis and asthma syndrome based on WeChat mini program can effectively improve the compliance of children and their family, improve the control level of allergic rhinitis and asthma.
ABSTRACT
Objective@#To evaluate the residual radioactivity after 131I treatment in postoperative inpatients with differentiated thyroid carcinoma (DTC) using service robot in nuclear medicine ward, and assess the time for patients to be released from isolation.@*Methods@#From September 2017 to June 2018, 297 patients (94 males, 203 females, age: 19-80 years) with DTC who underwent 131I treatment after surgery were included. According to the purpose of treatment and the prescription dosage of 131I, patients were divided into 8 groups: 4 groups accepted 131I remnant ablation therapy (RAT) with different dosages, which were 3 700 MBq (RAT1, n=34), 4 440 MBq (RAT2, n=122), 5 550 MBq (RAT3, n=81) and 7 400 MBq (RAT4, n=27), respectively; 4 groups had 131I treatment for recurrent/metastatic lesions (RMLT), and the dosages were 3 700 MBq (n=1), 4 440 MBq (n=2), 5 550 MBq (n=14) and 7 400 MBq (n=16). At 4, 24, 48 and 72 h after 131I administration, the dose equivalent rates at 2 cm away from the patient′s neck and at 1 m away from the body were measured by the robot designed for nuclear medicine ward. Kruskal-Wallis rank sum test and Mann-Whitney U test were used to analyze the data.@*Results@#Neck dose equivalent rates for patients with RAT at different time points (4, 24, 48 and 72 h) after 131I administration were significantly different among 4 groups (H values: 20.889-46.410, all P<0.05), as well as the body dose equivalent rates (H values: 27.181-35.497, all P<0.05). The neck dose equivalent rates at 24, 48 and 72 h after 131I administration were statistically different between group 3 and 4 for patients with RMLT (z values: 2.328-3.076, all P<0.05; data in group 1 and 2 were too limited to be compared), while there was no statistical difference for the body dose equivalent rates (z values: 0.333-1.621, all P>0.05). The radioactivity retention in patients decreased rapidly within 24 h, then slowed down gradually and became extremely low at 72 h. At 72 h after 131I administration, 96.6%(255/264) patients with RAT and 100%(33/33) patients with RMLT were lower than 23.3 μSv/h, which meant the patients could be discharged from hospitalization.@*Conclusions@#Nuclear medicine ward service robots may dynamically measure residual radioactivity in DTC patients who take 131I treatment, providing individualized isolation solutions.

ABSTRACT
OBJECTIVE@#To investigate the influences of staphylococcus aureus in planktonic and biofilm forms on the expression of lysozyme, SLPI and gp340 in the human sinonasal explant model.@*METHOD@#Mucosa samples from ethmoid sinus were collected from ten patients of cerebrospinal fluid leak and were cultured with and without S. aureus biofilms and planktonic cells. After the infection, the explant model was confirmed by CLSM, and the secretion of lysozyme, SLPI and gp340 was detected by enzyme-linked immunosorbent assay (ELISA) at 8, 16, and 24 h after S. aureus challenge. Expressions of lysozyme, SLPI and gp340 in mRNA and protein levels after 24 h S. aureus challenge were detected using RT-PCR, immunohistochemistry and Western bolt assay respectively.@*RESULT@#The secretion of lysozyme, SLPI and gp340 in the explant model was observed with a trend to increase in a time-dependent manner. At 8 and 16 h after S. aureus challenge, the secretion of lysozyme, SLPI and gp340 in biofilms group was significantly higher than these in planktonic cells group and control group (P 0.05), the biofilms enhanced the expressions of lysozyme, SLPI and gp340 significantly compared with planktonic cells and controls (P < 0.05).@*CONCLUSION@#S. aureus biofilm induced the expressions of lysozyme, SLPI and gp340 to a higher level than planktonic cells, indicating that S. aureus biofilm was an influencing factor on the innate immune system.
