Abstract
Objective: To investigate the prenatal diagnosis, integrated management and prognosis of fetal complete transposition of the great arteries (D-TGA) detected by ultrasonography. Methods: The prenatal diagnosis, integrated management and prognosis of 19 D-TGA fetuses found by ultrasound during pregnancy in Peking University People's Hospital from January 2014 to June 2019 were analyzed retrospectively. Results: The incidence of D-TGA was 0.12% (19/16 028) among fetuses diagnosed by ultrasound during 5 years. Among the 19 cases, there were 7 cases (7/19) of D-TGA alone, 7 cases (7/19) of D-TGA combined with ventricular septal defect (VSD), 5 cases (5/19) of D-TGA combined with other cardiac malformations; 2 cases (2/19) of D-TGA combined with extra cardiac malformations, and 1 case (1/19) of fetal growth restriction. Nuchal translucency (NT) thickening was found in 3 cases (3/19) at the first trimester of pregnancy. Among the 19 D-TGA fetuses found by ultrasound examination, 18 (18/19) had chromosome karyotype analysis of fetuses or newborns, and chromosomal abnormalities were found in 2 cases, all of which were terminated in the second trimester of pregnancy. The integrated management and multidisciplinary diagnosis and treatment of D-TGA fetuses during pregnancy and perinatal period were carried out. Nine cases (9/19) had induction in the second trimester of pregnancy, 10 cases (10/19) were delivered at term, and the gestational week of delivery was (38.3±0.7) weeks, among which 6 cases (6/10) were delivered by caesarean section due to obstetric factors, and 4 cases (4/10) were delivered by vaginal birth. The oxygen saturation was (69.2±11.3)% at birth and (77.8±6.7)% when transferred to the department of pediatrics. Except for one case lost to follow-up, the other 9 newborns received operation. The average operation time was (21.8±22.1) days after birth, 8 cases (8/9) completed one operation and 1 case (1/9) performed two operations. All of the 9 cases treated by surgery were followed up well. Conclusions: Prenatal diagnosis, individualized evaluation and integrated management during pregnancy and perinatal period should be carried out for the patients with fetal D-TGA detected by ultrasound. Fetal D-TGA is not an indication of cesarean section. The open of ductus arteriosus can be maintained with drugs when necessary after birth, and a good prognosis could be obtained through surgery.

Abstract
Mining data in depth of genome-wide sequencing data generated from pathological target tissues under disease conditions is necessary for seeking novel functional genes, and developing more biological study directions for the field. Based on our previous published RNA-seq data generated from acute myocardial ischemia and ischemia-reperfusion in rat heart, we re-analysed these two data sets using bioinformatics tools. All these raw fastq files were extracted from Illumina BCL using the Illumina CASAVA program. Four groups were obtained: UD (genes up-regulated in MI but down-regulated in I/R injury), DU (genes down-regulated in MI but up-regulated in I/R injury), UU (genes both up-regulated in MI and I/R injury), and DD (genes both down-regulated in MI and I/R injury) groups. The results showed that 304 common genes in the UD group, 236 common genes in the DU group, 318 common genes in the UU group, and 159 common genes in the DD group detected by comparing data sets of the MI and the I/R injury. We then listed the top 30 DEGs for each group, and carried out GO and KEGG analyses for enrichment and pathway studies for those top expressed genes. Further analysis of INTERPRO Protein Domains and Features enriched by DEGs showed that 20% of the Domains enriched were related to c-type lectin, and 17% of these domains are related to neurotransmitter-gated ion-channel. 15% of PFAM Protein Domains were about Neurotransmitter-gated ion-channel. There were only 8 SMART Protein Domains DEGs enriched and 37.5% of which were concerned about leucine-rich. Collagen involvement in Reactome Pathways accounted for 22.7%. We found that only a few DEGs in these two disease conditions have been reported in the literatures, suggesting that there are many new genes would be considered in the future studies. These analyses would provide some information for seeking more novel targets of these two clinic diseases, acute myocardial ischemia and myocardial ischemia/reperfusion.

Abstract
Polyimide (PI) aerogels have attracted great attention owing to their low density and excellent thermal stability. However, hydrophobic surface modification is required for PI aerogels to improve their ability in oil/water separation due to their amphiphilic characteristic. Two-dimensional MXenes (transition metal carbides/nitrides) can be utilized as nanofillers to enhance the properties of polymers because of their unique layered structure and versatile interface chemistry. Herein, the robust, lightweight, and hydrophobic PI/MXene three-dimensional architectures were fabricated via freeze-drying of polyamide acid/MXene suspensions and thermal imidization. Polyamide acid was synthesized using N-N-dimethylacetamide and 4,4'-oxydianiline. MXene (Ti3C2Tx) dispersion was obtained via the etching of Ti3AlC2 and ultrasonic exfoliation. Taking advantage of the strong interaction between PI chains and MXene nanosheets, the interconnected, highly porous, and hydrophobic PI/MXene aerogels with low density were fabricated, resulting in the improved compressive performance, remarkable oil absorption capacity, and efficient separation of oil and water. For the PI/MXene-3 aerogel (weight ratio, 5.2:1) without any surface modification, the water contact angle was 119° with a density of 23 mg/cm3. This aerogel can completely recover to its original height after 50 compression-release cycles, exhibiting superelasticity and exceptional fatigue-resistant ability. It also showed high absorption capacities to various organic liquids ranging from approximately 18 to 58 times of their own weight. This hybrid aerogel can rapidly separate the chloroform, soybean oil, and liquid paraffin from the water-oil system. The thermally stable hybrid aerogel also exhibited excellent fire safety properties and outstanding reusability under an extreme environment.

Abstract
Objective: To explore the clinical characteristics of interrupted of the inferior vena cava with azygous continuation and the prognosis. Methods: Retrospective analysis of 21 fetuses diagnosed with interrupted inferior vena cava with azygous continuation among 28 567 pregnant women who underwent routine ultrasound scan. The clinical data, ultrasonographic features, genetic information and prognosis were collected. Results: Interrupted of the inferior vena cava with azygous continuation occurred in 21(0.07%, 21/28 567) of 28 567 patients. Three fetuses (14%, 3/21) complicated with heart and extracardiac malformations, including endocardiac cushion defect, single atrium and single ventricle, double superior vena cava, dextrocardia, asplenia syndrome, visceral heterotaxy, duodenal atresia; six fetuses (29%, 6/21) were associated with cardiac anomalies, such as hypoplastic left heart syndrome, double outlet right ventricle, pulmonary stenosis, ventricular septal defect, persistent left superior vena cava, endocardiac cushion defect and transposition of the great arteries; six cases (29%, 6/21) were only combined with extracardiac malformations, includingasplenia syndrome, visceral heterotaxy, duodenal atresia. Three fetuses (14%, 3/21) were nonorganic abnormalities included thickening of the right ventricle wall, fetal bradycardia, pericardial effusion, hydrops abdominis, increased peak systolic velocity/end diastolic velocity and single umbilical artery. Three fetuses (14%, 3/21) were isolated interrupted inferior vena cava with azygous continuation, but without other anomalies and 2 of them had normal fetal karyotype. Five cases (24%, 5/21) were successfully vaginal delivery, 1 case (5%, 1/21) had cesarean section. After 12-40 months follow-up, we didn't obeserve obviously abnormality, nor any chromosomal abnormality. Ten patients (48%, 10/21) opted for termination of the pregnancy and the autopsies were not done. Five cases (24%, 5/21) were lost to follow up. Conclusions: Interrupted inferior vena cava with azygous continuation are associated with cardiovascular and extracardiac anomalies, cardiac malformation and visceral heterotaxy are the most common anomalies. Visceral heterotaxy should be considered and fetal karyotype should be suggested. In the cases of isolated interrupted inferior vena cava with azygous continuation and normal karyotype, the outcome is favorable.

Abstract
Objective. To assess the effect of 7 d -6 degrees HDT on electromyogram of the weightbearing muscles. Method. Eight healthy males, aged 33-42, were exposed to -6 degrees HDT bed-rest for 7 d, electromyogram from the gastrocnemius and anterior tibialis muscles were recorded before and after HDT, and day 4 of recovery. Result. The latency of SLR (short latency response) recorded from lower leg muscles after HDT was not different from that pre-HDT. But the latency of MLR (middle latency response) and LLR (long latency response) after HDT were significantly increased as compared with that pre-HDT, and recovered to pre-HDT level on day 4 of recovery. The durations of SLR recorded from right leg muscles after HDT were significantly longer as compared with that pre-HDT, and did not recover. The integrated amplitude of SLR and MLR after HDT were significantly increased as compared with that pre-HDT, and only the integrated amplitude of SLR recovered, but that of MLR did not. Conclusion. Seven day -6 degrees HDT bed-rest had significant effects on electromyogram of the weightbearing muscles.

Abstract
OBJECTIVE To quantitatively assess the effects of 7 d -6 degrees head-down bed-rest (HDBR) on postural equilibrium and to investigate the contributions of vestibular, somatosensory and visual informations to postural equilibrium. METHOD Eight healthy males, aged 33 - 42 years, were exposed to -6 degrees head-down tilt bed rest for 7 d. Sensory Organization Test (SOT) and Motor Coordination Test (MCT) were measured before and after HDBR, and day 4 of recovery. RESULT Equilibrium scores of SOT in condition 1 (eyes opened, platform and visual scence environment fixed), 5 (eyes closed visual scence environment fixed, platform movable) were significantly lower as compared with pre-HDBR value, and recovered to pre-HDBR level on day 4 of recovery. Postural strategy scores of SOT in condition 1, 2 (eyes closed, platform and visual scence environment fixed) and 3 (eyes opened, platform fixed, visual scence environment movable) were significantly lower as compared with pre-HDBR value, and recovered to pre-HDBR level on day 4 of recovery. The dependence of somatosensory and visual information (ratio pair codition 2/condition 1, condition 3/condition 1 in sensory analysis) was significantly higher as compared with pre-HDBR value, and recovered on day 4 of recovery. Mean SOT alignment scores in conditions 1, 4 (eyes opened, visual scence environment fixed, platform movable) and 6 (eyes opened, platform and visual scence environment movable) were significantly higher as compared with pre-HDBR value, and only the scores of conditions 1, 6 were recovered on day 4 of recovery, but that of condition 4 did not. Mean postural-evoked response latencies of MCT were not significantly different as compared with pre-HDBR value. CONCLUSION 7 d -6 degrees head-down tilt bed-rest has significant effects on postural equilibrium. The contributions of somatosensory and visual informations to postural equilibrium are increased.

Abstract
Objective. To study the characteristics of pilots' electrocardiogram during parabolic flight. Method. Dynamic electrocardiogram (DCG, CM1 and CM5 bipolar leads) were recorded in 13 pilots before, during and after parabolic flights. Result. Preflight and postflight values of heart rate (HR) and cardiac rhythm were essentially the same in all cases, but HR increased to a higher level of 86.0 +/- 7.3 bpm with maximum of 137.0 +/- 12.2 bpm, and minimum of 57.7 +/- 6.6 bpm during parabolic flights. During flights, one pilot's cardiac rhythm changed slightly and in another pilot T wave became inverted. In other two pilots, ST segments shifted downward more than 0.1 mV transiently. All these pilots showed negative result in maximal exercise on the ground. Conclusion. DCG could be used to evaluate the changes of cardiac electric activity during the whole parabolic flight.

Abstract
OBJECTIVE To try to find a new method for countermeasuring the effect of simulated weightlessness. METHODS The study was carried out in fifteen male healthy subjects, 19-22 years, -6 degrees head-down bed rest (-6 degrees HDBR) for 21 d was used as a weightlessness simulation model. The subjects were divided into three groups: control group (-6 degrees HDBR), hypoxia group (-6 degrees HDBR + inhalation of hypoxic gas mixture two times a day, 20 min each time) and Qigong group (-6 degrees HDBR + Qigong, three times per day, 45 min each time). Orthostatic test (+75 degrees 20 min) was conducted on each subject pre- and post-HDBR. RESULTS Cardiac rhythm during the orthostatic test was normal pre-HDBR but sinus cardiac arrhythmias were observed in two subjects of the control group and nodal cardiac arrhythmias were observed in two subjects in Qigong group after HDBR. No cardiac arrhythmia was found in hypoxia group. CONCLUSION Hypoxia is more effective in countermeasuring orthostatic intolerance after weightlessness than Qigong.

Abstract
Twenty-nine patients underwent closure of patent ductus arteriosus (PDA) via pulmonary arteriotomy under low-flow extracorporeal circulation combined with profound hypothermia. No complications from air embolism or hemorrhage were encountered during the operation. The early and late results were satisfactory. This technique was used as a safe method for PDA complicated by severe pulmonary hypertension, infective endocarditis, recurrence of ductal patency and for PDA in adults or coexistence of intracardiac anomaly.
