Objective: To investigate the posttraumatic growth and emotional regulation strategies of patients with moderate and severe burns at different time points in the rehabilitation period, and to explore the correlation between posttraumatic growth and emotional regulation strategies, so as to provide a basis for targeted nursing intervention. Methods: By convenience sampling method, 115 convalescent patients with moderate and severe burns in Linyi People′s Hospital burn plastic surgery center were investigated by General Information Questionnaire, Chinese Posttraumatic Growth Inventory (C-PTGI), Emotion Regulation Scale (ERQ) respectively on the day of discharge (T1), 3 months and 6 months after hospital discharge (T2, T3) from December 2017 to January 2019. Results: The post-traumatic growth scores of patients T1, T2 and T3 were 58.18±9.51, 48.65±9.31 and 47.43±8.76, respectively. The post-traumatic growth scores showed a downward trend at three time points, and the difference was statistically significant (F=339.732,P<0.01). The scores of T1, T2 and T3 in the cognitive reassessment dimensions of patients′emotion regulation strategies were respectively 27.10±4.13, 26.95±3.76, 26.11±3.60. The scores are going down and the differences were statistically significant (F=27.798, P<0.01). The expression inhibition scores were 14.42±4.39, 15.20±3.30, 15.21±3.56 respectively. The scores are the rise and the differences were statistically significant (F=13.675, P < 0.01). There were positive correlations between cognitive reassessment scores and posttraumatic growth scores、scores of all dimensions (r=0.230-0.555, P<0.05). The expression inhibition scores were negatively correlated with the total post-traumatic growth scores, personal strength, and scores of new possibility dimensions (r=-0.230--0.420, P<0.05). Conclusion Posttraumatic growth of patients with moderate to severe burns is not optimistic in the rehabilitation period. Therefore, it is necessary to pay attention to the guidance of emotional regulation strategies for patients with moderate to severe burns in the rehabilitation period, and carry out targeted interventions to promote the posttraumatic growth of patients.

Objective: To explore growth and intelligence development of low birth weight infants (LBWI) at 24 and 36 months of age, so as to provide reference for early monitoring and intervention of the development of LBWI. Methods: A total of 100 LBWI born and managed in Hefei Maternal and Child Health Care Institution were selected from 2012 October 1 to 2015 December 30, and 99 normal birth weight infants (NBWI) under child health management in the same sitinstitution were selected as controls. According a prospective cohort study method, and based on the establishment of a cohort and monitoring of childhood growth and development, a unified method was used to longitudinally follow up and observe the physical fitness of two groups of infants at the determined time points. The development of LBWI and NBWI at 24 and 36 months of age was surveyed using the Gesell Development Scale. Results: Weight, length and head circumference of LBWI children at the age of 15-36 months were significantly lower than those of NBWI children ( P <0.05). In addition, 117 children (43.98%) completed the full assessment of intelligent development scale, including 62 LBWI and 55 NBWI. The scores of Gesell in NBWI group was higher than that in LBWI group at 24 and 36 months of age, including adaptability, gross motor, fine metor skills, language and personal social functions ( t =-4.17, -3.82, -3.21 , -3.03, -2.61; -4.23, -3.16, -3.07, -3.13, -3.99, P <0.05). Multivariate linear regression analysis found that birth weight was positively correlated with adaptability, gross motor, fine motor skills, language functions at 24 and 36 months of age and personal social function at 36 months of age ( β =0.004, 0.010; 0.003, 0.008; 0.003, 0.007; 0.004, 0.009; 0.011, P ＜0.05). Conclusion The growth and development of LBWI children are significantly delayed compared to NBWI children. The scores of LBWI children are lower than those of NBWI children in all functional areas. Weight is the main factor affecting children s intellectual development. Early monitoring and intervention of low birth weight infants should be carried out to avoid or mitigate adverse consequences.

Objective To investigate the correlation between the manual compression on injection point and the incidence of subcutaneous bleeding after subcutaneous injection of low molecular weight heparin(LMWH)in elderly patients with coronary artery disease.Methods A total of 131 elderly patients with coronary artery disease,who received subcutaneous injection of LMWH after percutaneous coronary intervention(PCI)at the Affiliated Nanjing Hospital of Nanjing Medical University of China between January 2019 and December 2021,were enrolled in this study.According to whether the manual compression on the injection point was employed or not after the injection of LMWH,the patients were divided into the study group(n=67)and the control group(n=64).The operation process of subcutaneous injection of LMWH was carried out in accordance with the"Supervision Standard for Nursing Quality of Hypodermic Injection of Low Molecular Weight Heparin"which was included in the norms formulated by authors'hospital.For the patients of the study group,the injection point was manually pressed for 3-5 min after the injection of LMWH,the manually-used force was to press the skin down for 1cm deep.The incidence of subcutaneous bleeding was compared between the two groups.Results In the study group and the control group,the incidence of subcutaneous ecchymosis was 9.0%and 7.8%respectively,the incidence of subcutaneous hard tubercle was 4.5%and 1.6%respectively,the differences between the two groups were not statistically significant(both P＞0.05).The patient's age,gender,abdominal circumference and body mass index(BMI)carried no obvious correlation with the subcutaneous bleeding after LMWH injection(P＞0.05),while a statistically significant correlation existed between the abdominal wall fat thickness and the subcutaneous bleeding(P＜0.05),which could be used as an independent predictor for the occurrence of subcutaneous bleeding after LMWH injection.Conclusion No obvious correlation exists between the manual compression on injection point and the incidence of subcutaneous bleeding in elderly patients with coronary artery disease after subcutaneous injection of LMWH,therefore,no compression manipulation,used as a hemostatic measure,is required after subcutaneous injection of LMWH.The abdominal wall fat thickness is an independent predictor for subcutaneous bleeding after injection of LMWH.Standard operation procedures should be strictly followed so as to avoid the occurrence of subcutaneous bleeding after injection of LMWH.(J Intervent Radiol,2024,32:77-81)

Objective:To evaluate the interaction between remimazolam and propofol for sedation during hysteroscopy.Methods:American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 20-45 yr, with body mass index of 18-28 kg/m 2, scheduled for elective hysteroscopy, were included. The test was conducted in two steps. Up-and-down sequential allocation was used to determine the median effective dose (ED 50) of remimazolam (group A) and propofol (group B). The ED 50 obtained in A and B groups were then used as the standard to determine the combination regimen in group C (0.25×ED 50 of remimazolam+ 0.75×ED 50 of propofol as the initial dose), in group D (0.5×ED 50 of remimazolam+ 0.5×ED 50 of propofol as the initial dose), and in group E (0.75×ED 50 of remimazolam+ 0.25×ED 50 of propofol as the initial dose). Up-and-down sequential allocation was used to determine the ED 50 of propofol when propofol and remimazolam were combined in C, D and E groups. The interaction between the sedative effects of two drugs was analyzed using the isobolographic analysis method, and the interaction coefficient and synergistic dose ratio of two drugs were calculated. Results:The ED 50 of remimazolam was 0.180 mg/kg in group A, and the ED 50 of propofol was 1.167 mg/kg in group B. The results of isobolographic analysis showed that remimazolam and propofol had a synergistic effect. When remimazolam 0.045, 0.090 and 0.135 mg/kg were combined with propofol 0.546, 0.288 and 0.160 mg/kg, the interaction coefficients were 1.393, 1.339 and 1.127 respectively. The synergistic dosage ratio of remimazolam and propofol was 1.0∶(3.2 to 12.0). Conclusions:Remimazolam and propofol have a synergistic effect on sedation when used for hysteroscopy, and the dose ratio is 1.0∶(3.2-12.0).

Objective:To predict and evaluate the antibacterial efficacy of linezolid, teicoplanin and daptomycin against Staphylococci bloodstream infections with Monte Carlo simulation, and to optimize the clinical administration program. Methods:A total of 1 847 Staphylococci strains isolated from blood samples between January 2018 to December 2019 were collected with the help of the Blood Bacterial Resistant Investigation Collaborative System (BRICS). Minimum inhibitory concentrations (MIC) of linezolid and daptomycin were detected by broth dilution method, while MIC of teicoplanin were detected by agar dilution method. The dosage regimens of linezolid were 800 mg once daily, 500 mg once every 12 hours, 600 mg once every 12 hours and 600 mg once every eight hours. The dosage regimens of teicoplanin were 400 mg once every 12 hours, 600 mg once every 12 hours, 800 mg once every 12 hours, and 1 000 mg once every 12 hours. The dosage regimens of daptomycin were 4 mg·kg -1·d -1, 6 mg·kg -1·d -1, 8 mg·kg -1·d -1, 10 mg·kg -1·d -1and 12 mg·kg -1·d -1. The probability of target attainment (PTA) and cumulative fraction of response (CFR) of three different dosage regimens were calculated by Monte Carlo simulation. A dosage regimen with CFR≥90.0% was a reasonable choice for empirical antimicrobial therapy. Results:PTA of linezolid against Staphylococci when MIC≤0.500 mg/L at four dosage regimens (800 mg once daily, 500 mg once every 12 hours, 600 mg once every 12 hours and 600 mg once every eight hours) were all over 90.0%. When MIC was 1.000 mg/L, the PTA of linezolid against Staphylococci under the dosages of 500 mg once every 12 hours, 600 mg once every 12 hours and 600 mg once every eight hours were 92.2%, 96.6% and 97.6%, respectively. The CFR of the four dosage regimens of linezolid were 73.9%, 83.7%, 90.8% and 95.3%, respectively. When MIC≤1.000 mg/L, PTA of teicoplanin against Staphylococci were all 100.0% at four dosage regimens (400 mg once every 12 hours, 600 mg once every 12 hours, 800 mg once every 12 hours and 1 000 mg once every 12 hours). When MIC was 2.000 mg/L, the PTA of teicoplanin (800 mg once every 12 hours and 1 000 mg once every 12 hours) against Staphylococci were both 100.0%. The CFR of the four dosage regimens of teicoplanin were 90.8%, 92.8%, 93.5% and 94.6%, respectively. When MIC≤0.500 mg/L, PTA of daptomycin against Staphylococci under the five dosages of 4 mg·kg -1·d -1, 6 mg·kg -1·d -1, 8 mg·kg -1·d -1, 10 mg·kg -1·d -1 and 12 mg·kg -1·d -1 were all over 90.0%. When MIC was 1.000 mg/L, the PTA of daptomycin against Staphylococci under the three dosages of 8 mg·kg -1·d -1, 10 mg·kg -1·d -1 and 12 mg·kg -1·d -1were 96.9%, 100.0% and 100.0%, respectively. The CFR of the five dosage regimens of daptomycin against Staphylococci were 97.4%, 99.2%, 99.9%, 100.0% and 100.0%, respectively. Conclusions:Linezolid (600 mg once every 12 hours), teicoplanin (400 mg once every 12 hours) and daptomycin (4 mg·kg -1·d -1) can achieve satisfactory antibacterial activity for Staphylococci bloodstream infections.

Objective:To compare the effects of different test meals on postprandial triglycerides and to optimize the standard meal composition and the blood sampling protocol for the oral fat tolerance test.Methods:This study is a prospective, open-label, randomized, cross-over trial. In March 2023, 36 volunteers were recruited in Hebei General Hospital. They underwent a health examination and oral glucose tolerance test. Twenty-six healthy volunteers(11 males and 15 females) were included in this study, with an average age of(39.08±4.56) years. Each volunteer received 75 g protein meal, 75 g fat meal, 700 kcal fixed-calorie high-fat mixed meal, and a high-fat mixed meal with energy adjusted based on 10 kcal/kg body weight. A one-week washout period of regular diet was applied before each trial. Blood was collected at fasting status and 1, 2, 3, 4, 5, and 6 hours after a meal to detect serum triglycerides, total cholesterol, low density lipoprotein-cholesterol(LDL-C), high density lipoprotein-cholesterol(HDL-C), glucose, and insulin. The variations of postprandial metabolic indicators over time following the consumption of different test meals were analyzed. The disparities in postprandial metabolic responses between the two types of mixed meals were compared.Results:The protein meal, fat meal, fixed-calorie high-fat mixed meal, and adjusted-calorie high-fat mixed meal resulted in postprandial triglyceride increases of 22.45%, 115.40%, 77.14%, and 63.63%, and insulin increase of 560.43%, 85.69%, 554.18%, and 598.97%, respectively, and with reductions in total cholesterol, LDL-C, and HDL-C ranging from 5.64%-21.81%, respectively. The blood glucose changed slightly. Changes in metabolic indicators mainly occured within 4 hours. The comparison of the characteristics of postprandial triglycerides between the two high-fat mixed meals showed no statistically significant differences( P>0.05). Conclusion:A standardize protocol with a 700 kcal fixed-calorie high-fat mixed meal as test meal, and blood lipid levels measured at fasting and at 1, 2, 3, and 4 hours after consumption, can serve as an optimized approach for oral fat tolerance test.
