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.

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.

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.

BACKGROUND: Simple nanotube surface modification of titanium implant has been shown to promote adhesion, proliferation and differentiation of osteoblasts. Collagen coating can promote osteoblast adhesion and osseointegration in vivo. OBJECTⅠVE: To observe the effects of type collagen combined titanium dioxide nanotube composite coating modified titanium surface on osteoblast adhesion in vitro and osseointegration in vivo. METHODS: The titanium dioxide nanotube was fabricated on the pure titanium surface, then type Ⅰ collagen was combined with the nanotube structure to form composite coating. Scanning electron microscope observation was used to characterize the surface topography of the pure titanium, titanium dioxide nanotube and type Ⅰ collagen combined titanium dioxide nanotube surfaces. Contact angle test was employed to evaluate the hydrophilicity of different samples. MC3 T3-E1 murine preosteoblasts were seeded on the three kinds of materials for 4 hours. Cell adhesion morphology was examined by scanning electron microscope. Adherent cell counting was detected under inverted fluorescence microscope. Expression of actin cytoskeleton and vinculin was observed under laser scanning confocal microscope. The gene expression of vinculin and osteoprotegerin mRNA was detected by real-time quantitative PCR. The three kinds of samples were implanted into the tibia of Sprague-Dawley rats (provided by Laboratory Animal Center, Ⅰnstitute of Radiation Medicine, Chinese Academy of Medical Sciences) , and tibia samples were removed after 4 weeks of implantation for biological push-out test and histological observation. RESULTS AND CONCLUSⅠON: (1) Scanning electron microscope: There was mechanical scratch on the pure titanium surface. There was controllable, and uniform vertical arrangement of nanotubular structures with a diameter of approximately 70 nm on the titanium dioxide nanotube surface, and collagen adhered surrounding the nanotubular structures on the type Ⅰ collagen combined titanium dioxide nanotube substrate, and partial tubule orifices were closed. (2) The hydrophicility of type Ⅰ collagen combined titanium dioxide nanotube was significantly larger than those of the other two materials (P < 0.05) . (3) Compared with the pure titanium and titanium dioxide nanotube surfaces, the type Ⅰ collagen combined titanium dioxide nanotube substrate displayed increased adherent cell number, much well-organized cytoskeleton, enhanced immunofluorescence intensity of vinculin protein staining, and increased expression levels of vinculin and osteoprotegerin mRNA levels (all P < 0.05) . (4) Ⅰn vivo test revealed that the maximum push-out force in the type Ⅰ collagen combined titanium dioxide nanotube group was significantly higher than that in the pure titanium and titanium dioxide nanotube groups (P < 0.05) . Hematoxylin-eosin staining results showed that there were few bones, but many fibrous connective tissue surrounding the implant in the pure titanium group; there were more newly-born bones, and less fibrous connective tissue surrounding the implant in the titanium dioxide nanotube group; there were dense newly-born bones, and few thin fibrous connective tissue surrounding the implant in the type Ⅰ collagen combined titanium dioxide nanotube group. (5) These results indicate that type Ⅰ collagen combined titanium dioxide nanotube surface can facilitate osteoblast cell adhesion and promote osseointegration in vivo.

Objective? To explore the effect of the mobile-app-based case management on functional rehabilitation among breast cancer patients after operation. Methods? A total of 120 breast cancer patients who had undergone axillary lymph node dissection in a ClassⅢ Grade A hospital in Zhengzhou city from January to December in 2017 were selected by convenient sampling. According to their admission time, 60 in-patients who were admitted between January and June in 2017 were assigned into the control group, and the other 60 in-patients who were admitted between July and December in 2017 were put into the observation group. In the control group, the patients were given by regular functional rehabilitation guidance for the affected limb while in the observation group, the patients were managed by mobile-app-based system besides the regular guidance. For both groups, the follow-up visit lasted for 6 months after surgery. The patients' incidence of edema, upper limbs and shoulder joints' function as well as their quality of life were compared and studied. Results? The incidence of lymphedema at one month and six months after surgery in the observation group were lower than the control group with statistical significance (P＜ 0.05). Six months after surgery, the patients in the observation group were better than the control group in terms of the joint function, quality of life except the emotional condition with statistically significant difference(P＜0.05). Conclusions? The implementation of the mobile-app-based case management for postoperative breast cancer patients can effectively promote the postoperative functional rehabilitation of affected limbs, reduce the occurrence of postoperative lymphedema, and improve their quality of life.
