OBJECTIVE To analyze the current situation of drug use in domestic aeromedical rescue， and provide references for the development of aeromedical rescue services and the rational use of drugs on board. METHODS All literature on aeromedical rescue in China were retrieved from the databases of SinoMed， CNKI， VIP， and Wanfang data up to September 1st， 2024. Extracting descriptive analysis were conducted on the literature screened by the inclusion and exclusion criteria. RESULTS A total of 36 literature were included. Aeromedical rescue cases had been reported in China since 1985， with a cumulative total of 5 370 cases reported. Prehospital rescue performed 861 cases， with 96.40% of them involving the use of at least 9 categories， totaling at least 10 different drugs， primarily emergency drugs. Interhospital rescue performed 4 509 cases， and 85.23% of them used over 48 kinds of drugs across 19 categories， mainly emergency drugs supplemented by specialty drugs. From the view of transportation， 5 166 air transfers were made by helicopters， of which 88.00% involved the use of drugs， and 204 cases by fixed-wing aircraft， of which 91.18% involved the use of drugs. CONCLUSIONS Drugs are frequently used in aeromedical rescue involving a wide variety of types in China. It is imperative to strengthen the focus on the equipment and rational use of drugs in aeromedical rescue， thereby facilitating the establishment of a standardized theoretical framework.

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [¹⁵N₂]-cystine and [¹³C₅]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

OBJECTIVE To evaluate the levels of evidence and analyze the rationality for off-label use of tacrolimus in the kidney diseases in adults. METHODS By systematically reviewing the drug instructions, clinical guidelines and medical literature of tacrolimus in the kidney diseases in adults, screening the highest level of evidence, and an evaluation table based on evidence-based medical for off-label use of tacrolimus in the kidney diseases in adults was established. Based on the evaluation table, collect adult patients from the Department of Nephrology in Zhongda Hospital Southeast University who had a medication history of off-label use of tacrolimus from January 1, 2021 to December 31, 2022, and evaluated the rationality of application for tacrolimus. RESULTS A total of 19 indications for off-label use of tacrolimus in the kidney diseases in adults were listed, and their recommended levels were determined based on evidence. Among them, the recommended levels for common types of kidney diseases were higher. In addition, 194 adult patients with off-label use of tacrolimus were selected from the Department of Nephrology in Zhongda Hospital Southeast University, and their application recommended levels with "strongly recommended""moderately strongly recommended""weakly recommended" and "not recommended", were 67.0%, 12.9%, 15.0% and 5.1%, respectively. CONCLUSION Tacrolimus has a wide range of indications for off-label use in the kidney diseases in adults, but the evidence for most common types of kidney diseases are relatively sufficient and their use are reasonable.

In light of the lack of reliable molecular markers for odontogenic myxoma (OM), the detection of copy number variation (CNV) may present a more objective method for assessing ambiguous cases. In this study, we employed multiregional microdissection sequencing to integrate morphological features with genomic profiling. This allowed us to reveal the CNV profiles of OM and compare them with dental papilla (DP), dental follicle (DF), and odontogenic fibroma (OF) tissues. We identified a distinct and robustly consistent CNV pattern in 93.75% (30/32) of OM cases, characterized by CNV gain events in chromosomes 4, 5, 8, 10, 12, 16, 17, 20, and 21. This pattern significantly differed from the CNV patterns observed in DP, DF, and OF. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated potential links between this CNV patterns and the calcium signaling pathway and salivary secretion, while Gene Ontology (GO) term analysis implicated CNV patterns in tumor adhesion, tooth development, and cell proliferation. Comprehensive CNV analysis accurately identified a case that was initially disputable between OF and OM as OM. Our findings provide a reliable diagnostic clue and fresh insights into the molecular biological mechanism underlying OM.

Objective:To investigate the prevalence of pretreatment drug resistance and the genetic polymorphism of CRF08_BC strains among HIV-1 patients in China.Methods:This cross-sectional survey involved the plasma samples of HIV patients in a national pretreatment HIV drug resistance survey conducted in 2018. RNA was extracted from the samples. The fragments containing protease and partial reverse transcriptase (PR/RT) regions were obtained and sequenced. Drug resistance was analyzed using Stanford HIVdb Program. Differences in polymorphic mutations between drug-resistant and non-drug-resistant HIV-1 strains were analyzed by Chi-square test or Fisher′s exact test. The association between drug-resistant and polymorphic mutations was evaluated using CorMut R package. Molecular transmission networks were constructed using HIV-TRACE software. Results:Totally 465 partial pol sequences were obtained from individuals with CRF08_BC infection in 25 provinces and cities. The total pretreatment drug resistance rate was 17.8% (83/465). The pretreatment drug resistance rates to non-nucleoside reverse transcriptase inhibitors (NNRTIs), nucleoside reverse transcriptase inhibitors (NRTIs) and protease inhibitors (PIs) were 16.6% (77/465), 1.1% (5/465) and 0.9% (4/465), respectively. The resistance rate to rilpivirine (RPV) was the highest (15.7%, 73/465). The most common mutation was E138A (11.6%, 54/465). There were six polymorphic mutations (S162C, K102Q, T200A, V179E, I202V, T200M) that co-variated with E138A. The molecular transmission network showed that patients infected with CRF08_BC strains carrying the resistant mutations at position E138 mainly gathered in clusters in Yunnan and Sichuan, and the highest degree of connection was in Lincang, Yunnan. Conclusions:In China, HIV-1 CRF08_BC-infected patients showed a high rate of pretreatment resistance to one of the second-generation NNRTIs, namely RPV. Further researches were warranted to evaluate the impacts of co-mutations of the E138A mutation and polymorphic sites on HIV resistance and replicative capacity.

Objective:The aim of this randomized, double-blind trial was to evaluate the safety and tolerability profile, including cardiac safety, of sugammadex-mediated recovery from neuromuscular block in participants undergoing surgery who met the American Society of Anesthesiologists (ASA) Physical Class 3 or 4 criteria.Specifically, this study assessed the impact of sugammadex on cardiac adverse events (AEs) and other prespecified AEs of clinical interest.Methods:Participants meeting ASA Class 3 and 4 criteria were stratified by ASA Class and NMBA (rocuronium or vecuronium) then randomized to one of the following: 1) Moderate neuromuscular block, sugammadex 2 mg/kg; 2) Moderate neuromuscular block, neostigmine and glycopyrrolate (neostigmine/glycopyrrolate); 3) Deep neuromuscular block, sugammadex 4 mg/kg; 4) Deep neuromuscular block, sugammadex 16 mg/kg (rocuronium only). Primary endpoints included incidences of treatment-emergent (TE) sinus bradycardia, TE sinus tachycardia and other TE cardiac arrhythmias.Results:Of 344 participants randomized, 331 received treatment (61% male, BMI 28.5 ± 5.3 kg/m 2, age 69 ± 11 years). Incidence of TE sinus bradycardia was significantly lower in the sugammadex 2 mg/kg group vs neostigmine/glycopyrrolate.The incidence of TE sinus tachycardia was significantly lower in the sugammadex 2 and 4 mg/kg groups vs neostigmine/glycopyrrolate.No significant differences in other TE cardiac arrythmias were seen between sugammadex groups and neostigmine/glycopyrrolate.There were no cases of adjudicated anaphylaxis or hypersensitivity reactions in this study. Conclusions:Compared with neostigmine/glycopyrrolate, incidence of TE sinus bradycardia was significantly lower with sugammadex 2 mg/kg and incidence of TE sinus tachycardia was significantly lower with sugammadex 2 mg/kg and 4 mg/kg.These results support the safety of sugammadex for reversing rocuronium- or vecuronium-induced moderate and deep neuromuscular block in ASA Class 3 or 4 participants.

Objective:To explore the characteristics and differences of oxygenated hemoglobin responses in different brain regions in adolescent depressive disorder patients and healthy adolescents during speech fluency task based on functional near-infrared spectroscopy imaging.Methods:From March 2021 to June 2021, twenty-nine adolescents with depression(depressed group) and 26 healthy adolescents(normal group) were enrolled. The severity of depression was assessed by Hamilton depression scale, and the speech fluency task was performed by functional near-infrared spectroscopy brain imaging, and the relative concentrations of oxyhemoglobin in the prefrontal and bilateral temporal lobes were measured.SPSS 26.0 statistical software was used for data analysis, chi-square test was used for gender count data. The t-test was used for comparison of two groups. The measurement data that did not conform to normal distribution were compared between the two groups by Mann-Whitney U test. Results:In the speech fluency task, there was no significant difference in the concentration of oxygenated hemoglobin in prefrontal and left temporal between the depressed group and the normal group (both P>0.05); the oxygenated hemoglobin concentration in the right temporal lobe(-9.179(-22.231, 4.789)) of depressed group was significantly lower than that of the normal group (12.754(-9.438, 35.008)), and the difference was statistically significant ( U=538.00, P<0.05). The oxygenated hemoglobin concentration in right temporal lobe of depressed group had no correlation with the score of Hamilton depression rating scale ( r=0.092, P>0.05). Conclusion:The right temporal lobe function of adolescent depression patients is lower than that of healthy controls during speech fluency tasks, which provides a basis for study of the relationship between depression and some cognitive sensitivity impairment and the function of right temporal lobe.

Objective:To explore the effects of individualized psychological nursing in Operating Room in patients undergoing combined spinal and epidural anesthesia for hip replacement.Methods:Total of 95 patients undergoing combined spinal and epidural anesthesia for hip replacement at Henan Provincial People's Hospital from July 2019 to September 2020 were selected by convenient sampling. 47 patients treated from July 2019 to February 2020 were included into the control group which received routine Operating Room nursing, while 48 patients treated between February and September 2020 were included into the observation group which received individualized psychological nursing in operating rooms based on the care provided to the control group. The bad mental state, degree of fear, and degree of surgical cooperation were compared between the two groups of patients before and after operation.Results:After operation, the Depression Anxiety Stress Scale-21 scores and the degree of fear were lower in the observation group than in the control group, and the differences were statistically significant ( P<0.05) ; the observation group had higher cooperation in the operation than the control group, and there was statistically significant difference ( P<0.05) . Conclusions:The use of individualized psychological nursing in Operating Room in patients undergoing combined spinal and epidural anesthesia for hip replacement can effectively reduce the surgical pressure of the patient, relieve their anxiety, depression, fear, and improve their surgical cooperation.

Objective:To explore the effects of Williams life skills training on the coping style of parents of systemic lupus erythematosus (SLE) children.Methods:From March to December 2017, we selected 73 parents of 73 SLE children hospitalized in the Pediatric Ward of a Class Ⅲ Grade A hospital in Beijing as the research object by convenience sampling. All parents were randomly divided into intervention group ( n=37) and control group ( n=36) . During the hospitalization of the child, control group provided the SLE general knowledge, medication knowledge, daily care, attentions and other health education for the child's parents and answered questions raised by the child's parents at any time. On this basis, intervention group received the Williams life skills training (WLST) for 4 times, and the follow-up was carried out by WeChat or phone every week after discharge of children. The coping styles of two groups were evaluated with the Simple Ways of Coping Questionnaires before intervention, before discharge, one month and three months after intervention. Results:There were no statistical differences in the scores of positive coping subscale and negative coping subscale of the child's parents between two groups before intervention ( P>0.05) . At each time point after intervention, the score of positive coping subscale of intervention group was higher than that of control group, and the score of negative coping subscale was lower than that of control group with statistical differences ( P<0.01) . Conclusions:WLST can enhance the positive coping of parents of children with SLE, weaken their negative coping and effectively improve their coping styles.

Objective To examine the prevalence of obstructive sleep apnea (OSA) in patients with acute coronary syndrome (ACS),and to evaluate the relationship of OSA with inflammatory biomarkers in ACS patients.Methods Patients with ACS treated at Beijing Anzhen Hopital from June 2015 to May 2017 were enrolled.Subjects were evaluated for OSA by sleep study,and were divided into a normal-mild OSA group (Apnea Hypopnea Index,AHI ＜ 15 times/h) and a moderate-severe OSA group (AHI ≥ 15 times/h).Laboratory examination and sleep study were monitored to analyze the effects of OSA on biomarkers by LSD-t test,Mann-whitney U test,or Chi-square test.Correlation analysis was performed to analyze the association of OSA with high sensitivity C-reactive protein (hs-CRP) by Spearman correlation anaylsis.Results A cohort of 836 patients with ACS were enrolled including 408 patients in the normal-mild OSA group and 428 patients in the moderate-severe OSA group.The levels of leukocyte(x 109L) [7.78 (6.33,9.86) vs 7.29 (6.01,9.16),P=0.006],neutrophils(× 109L) [5.05 (3.84,7.23)vs 4.80 (3.74,6.66),P=0.044],monocytes(x 109L) [0.42 (0.33,0.54) vs 0.39 (0.31,0.51),P=0.033],hsCRP(mg/L) [3.18 (1.10,11.52) vs 1.78 (0.65,6.46),P＜0.01],fibrinogen(g/L) [3.17 (2.87,3.74) vs 2.97 (2.59,3.50),P=0.002],and uric acid(μmol/L) [360 (302,422) vs 341(283,407),P=0.006] in the moderatesevere OSA group were significant higher than those in the normal-mild OSA group.AHI (correlation coefficient=0.171,R2=0.020,P＜0.01),ODI (correlation coefficient =0.201,R2=0.027,P＜0.01),and TSaO2 ＜ 90％ (correlation coefficient =0.105,R2=0.005,P＜0.01) were positively correlated with hs-CRP;minimal SaO2 (correlation coefficient=-0.100,R2=0.001,P=0.008) and mean SaO2 (correlation coefficient =-0.127,R2=0.006,P＜0.01) were negatively correlated with hs-CRP.Conclusions For patients with ACS,the level of inflammatory markers in the moderate-severe OSA group is significantly higher than that in the normal-mild OSA group.Hs-CRP is significantly associated with the severity of OSA.Diagnosis and monitoring of OSA should be considered in ACS management in the future.
