Objective:To investigate the clinical application of noninvasive high frequency oscillatory ventilation(nHFOV)and heated humidified high flow nasal cannula(HHHFNC)in sequential ventilator evacuation of preterm infants with very low birth weight with respiratory distress syndrome(RDS).Methods:A total of 88 preterm infants of very low birth weight with RDS were enrolled in the study, who had received endotracheal intubation invasive ventilation and were ready to be replaced by non-invasive ventilation at neonatal intensive care unit(NICU)of Xuzhou Central Hospital from May 2017 to January 2020.All premature infants were routinely treated with caffeine citrate.They were divided into two groups through random number table: nHFOV/HHHFNC group(45 cases)and continuous positive airway pressure(nCPAP)/oxygen hood group(43 cases). nHFOV was given after invasive ventilator removal and HHHFNC transition was followed after nHFOV withdrawal in the nHFOV/HHHFNC group, while nCPAP was given after invasive ventilator removal and oxygen hood was followed after nCPAP withdrawal in the nCPAP/oxygen hood group.The main observation consequences were compared with arterial blood gas indexes after invasive ventilator evacuation, weaning effect and the incidence of related complications.Results:(1)There were no statistically differences between the two groups in terms of gender, gestational age, birth weight, Apgar score at 1 min and 5 min after birth, the number of glucocorticoid usage in 24 h before delivery, the number of pulmonary surfactant usage, invasive ventilation time and RDS grading( P>0.05). (2)The PaO 2, PaCO 2and oxygenation index(OI=100×MAP×FiO 2/PaO 2)of the nHFOV/HHHFNC group at 1 h and 24 h after invasive ventilator removal showed significant difference compared with the nCPAP/oxygen hood group( P<0.05). The differences as the following listed were statistically significant( P<0.05)between the two groups, including the failure rate of invasive ventilation weaning during 72 h [9%(4/45)vs.26%(11/43)], the incidence of frequent apnea [7%(3/45)vs.23%(10/43)], the failure rate of nHFOV and nCPAP noninvasive ventilation weaning [4%(2/45)vs.21%(9/43)], the oxygen-used time [12.02(9.08~12.31)d vs.14.44(11.32~13.26)d] and the incidence of nasal injury [4%(2/45)vs.26%(11/43)]. (3)The time of the first noninvasive ventilation of nHFOV and nCPAP, the incidences of lung air leakage, neonatal necrotizing enterocolitis, grade Ⅲ to Ⅳ intraventricular hemorrhage, above stageⅡretinopathy, bronchopulmonary dysplasia and the mortality rate between the two groups showed no statistical significance( P>0.05). Conclusion:nHFOV and HHHFNC used in the sequential ventilator evacuation of RDS in preterm infants with very low birth weight could improve oxygenation, reduce CO 2retention, improve the success rate of machine weaning and reduce the occurrence of apnea and nasal injury.

Small scale restricted online course (SPOCs)+flipped classroomteaching is expected to become an important complement to the traditional teaching of dermatology. In this teaching mode, first of all knowledge nodes are divided separately according to the syllabus and for each node, 7 to 10 minutes of micro video or micro-lecture is made, which enables students to make best use of fragmented time through the network to master relevant knowledge independently before the trainee. In the flipped classroom, based on the difficulties and misunderstandings of learning reflected from the network monitor data, teacher can make full use of time on demonstrating typical cases, organizing discussion, grouping students to take diag-nostic and therapeutic exercise, answering targeted questions, teaching clinical thinking, experience and doctor-patient communication skills. Through this teaching mode, the new teaching idea can be imple-mented that students are in dominant position while teachers are in leading position, which contributes to deepening the understanding , absorption and application of knowledge and improving students' ability of communication, cooperation, diagnosis and treatment.

Objective To investigate influence of exogenous insulin in all-in-one parenteral nutrition on blood glucose in infants with very low birth weight (VLBW). Methods Forty-two infants with VLBWI admitted to the department of pediatrics of Xuzhou Hospital affiliated to Southeast University during September 2005 to March 2009 were randomly assigned to Group Ⅰ ( n = 13 ) with exogenous insulin added to all-in-one parenteral nutrition at infusion rate of 0.4 U·kg-1·h-1,GroupⅡ(n = 13) with exogenous insulin at infusion rate of 0.1U·kg-1·h-1 and Group Ⅲ (n = 16) with no exogenous insulin added.Their blood glucose was monitored every two hours. Chi-square test was used for comparing difference in blood glucose abnormality between the three groups and association between blood glucose levels at admission and during hospitalization was analyzed with Spearman correlation. Results Incidence of hyperglycemia and hypoglycemia was 10. 9 percent (29/265) and 18. 1 percent (48/265) in Group Ⅰ, 20. 8 percent (59/284) and 14. 1 percent (40/284) in Group Ⅱ , and 20. 5 percent (61/298) and 11.7 percent (35/298) in Group Ⅲ, respectively. There was significant difference in incidence of hyperglycemia between Groups Ⅰ and Ⅱ ( x2 = 9. 844, P = 0. 002 ) and between Groups Ⅰ and Ⅲ ( x2 = 9. 478, P = 0. 002 ), but no significant difference in it between Groups Ⅱ and Ⅲ ( x2 = 0. 008, P = 0. 928 ). There was significant difference in incidence of hypoglycemia between Groups Ⅰ and Ⅲ ( x2 = 4. 526, P =0. 033 ), but no significant difference in it between Groups Ⅰ and Ⅱ (x2 =1.653, P=0. 199) or between Groups Ⅱ and Ⅲ (x2 =0.709, P =0.400).No significant correlation between endogenous blood insulin level at admission and during hospitalization( r = 0. 082, P = 0. 661 ) was found. Conclusions Blood glucose in infants with VLBW can not be regulated timely by their endogenous insulin itseff. Exogenous insulin added to all-in-one parenteral nutrition at infusion rate of 0. 1 U · kg-1 · h-1 may not significantly reduce incidence of hyperglycemia,while incidence of hypoglycemia can be reduced by exogenous insulin at infusion rate of 0. 4 U · kg- 1 · h -1 that can increase incidence of hypoglycemia Therefore, exogenous insulin is not recommended to be prophylactically added to all-in-one parenteral nutrition for infants with VLBW.

OBJECTIVENon-invasive positive pressure ventilation has increasingly been chosen as the primary ventilation mode in respiratory distress syndrome (RDS) in preterm infants. In order to further understand the application of various non-invasive positive pressure ventilation modes, we compared the advantages and disadvantages of three modes as a primary mode of ventilation in premature infants with RDS.
METHODFrom December 2011 to March 2013, 107 preterm infants with RDS who received intubation-pulmonary surfactant (PS) -extubation in our NICU were randomly divided (by means of random number table) into three groups based on the primary mode of ventilation: nasal continuous positive airway pressure [NCPAP, n = 39, male/female ratio was 27/12, mean gestational age (GA) was (32.0 ± 2.1)weeks, mean birth weight (BW) was (1752 ± 457)g], bi-level positive airway pressure [BiPAP, n = 35, male/female ratio was 25/10, GA was (31.4 ± 2.0) weeks, BW was (1530 ± 318) g], and synchronized bi-level positive airway pressure [SBiPAP, n = 33, male/female rate was 25/8, GA was (31.5 ± 2.2) weeks, BW was (1622 ± 447) g]. Ventilation settings including FiO(2) were adjusted according to transcutaneous SPO(2) monitoring or blood gas analysis. Various settings and adverse events were recorded as well. The main parameter was the FiO(2) at 24 h post-positive-pressure ventilation. Statistical analyses were performed using χ(2) test, rank sum test, one-way analysis of variance for least-significant difference value, paired-sample t-test, two related sample Wilcoxon signed rank sum test and Logistic regression.
RESULTThe PaCO(2) (mmHg, 1 mmHg = 0.133 kPa), oxygen index (OI) at 12-24 h, and FiO(2) at 24 h post-ventilation in BiPAP and SBiPAP groups were lower than that in NCPAP groups with significant difference (44 ± 9 and 45 ± 9 vs. 50 ± 9, 2.76 ± 0.96 and 2.79 ± 0.60 vs. 3.24 ± 0.72, 0.34 ± 0.10 and 0.35 ± 0.07 vs. 0.39 ± 0.07; F = 4.456, 5.146 and 4.123; P = 0.014, 0.007 and 0.019, respectively). There was no significant difference between BiPAP and SBiPAP groups. There was no significant difference among three groups (all P > 0.05) in the following events: respiratory index (RI) at 12-24 h post-ventilation, abdominal distension, period of non-invasive ventilation, ratio of intubation for invasive ventilation if failed noninvasive ventilation, air-leak syndrome, neonatal necrotizing enterocolitis, periventricular-intraventricular haemorrhage, bronchopulmonary dysplasia, retinopathy of prematurity, mortality rate after 36 h of age or rate of abandon for discharge. The independent risk factors for failure of non-invasive positive pressure ventilation were gender, gestational age, antepartum steroid at 24 h before birth to 7 d, and birth weight, with the OR (95% confidence interval) being 14.120 (1.135, 175.662), 2.862 (1.479, 5.535), 61.084 (3.115, 1 198.031), and 8.306 (1.488, 46.383), respectively.
CONCLUSIONAs the primary mode of ventilation in premature infants with RDS, both BiPAP and SBiPAP are more beneficial than NCPAP in improving oxygenation and reducing CO(2) retention without increasing the incidence of adverse events.

Objective To compare the effectiveness of snail control between immersion of molluscicides through tide diversion and mollusciciding by spraying in marshland areas. Methods Immersion of 26% suspension concentrate of metaldehyde and niclosamide through tide diversion and spraying 26% suspension concentrate of metaldehyde and niclosamide alone were employed for snail control in two neighboring snail-breeding marshlands, and snails were surveyed before and after mollusciciding. The mortality of snails and the density of living snails were estimated. Results The density of living snails reduced by 72.19% and 100.00% 1 and 2 years after immersion of 26% suspension concentrate of metaldehyde and niclosamide through tide diversion, and 5.93% and 18.15% 1 and 2 years after spraying 26% suspension concentrate of metaldehyde and niclosamide alone. Conclusion Immersion of 26% suspension concentrate of metaldehyde and niclosamide through tide diversion is significantly superior to spraying 26% suspension concentrate of metaldehyde and niclosamide along for snail control, and implementation of immersion of 26% suspension concentrate of metaldehyde and niclosamide through tide diversion for more than 2 successive years may achieve a higher snail control efficiency.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.
