Abstract
BACKGROUND Necroptosis is a novel type of programmed cell death distinct from apoptosis. However, the role of necroptosis in ovarian cancer (OC) remains unclear. The present study investigated the prognostic value of necroptosis-related genes (NRGs) and the immune landscape in OC. METHODS The gene expression profiling and clinical information were downloaded from the TCGA and GTEx databases. Differentially expressed NRGs (DE-NRGs) between OC and normal tissueswere identified. The regression analyses were conducted to screen the prognostic NRGs and construct the predictive risk model. Patients were then divided into high- and low-risk groups, and the GO and KEGG analyses were performed to explore bioinformatics functions between the two groups. Subsequently, the risk level and immune status correlations were assessed through the ESTIMATE and CIBERSORT algorithms. The tumor mutation burden (TMB) and the drug sensitivity were also analyzed based on the two-NRG signature in OC. RESULTS Totally 42 DE-NRGs were identified in OC. The regression analyses screened out two NRGs (MAPK10 and STAT4) with prognostic values for overall survival. The ROC curve showed a better predictive ability in five-year OS using the risk score. Immune-related functions were significantly enriched in the high- and low-risk group. Macrophages M1, T cells CD4 memory activated, T cells CD8, and T cells regulatory infiltration immune cells were associated with the low-risk score. The lower tumor microenvironment score was demonstrated in the high-risk group. Patients with lower TMB in the low-risk group showed a better prognosis, and a lower TIDE score suggested a better immune checkpoint inhibitor response in the high-risk group. Besides, cisplatin and paclitaxel were found to be more sensitive in the low-risk group. CONCLUSIONS MAPK10 and STAT4 can be important prognosis factors in OC, and the two-gene signature performs well in predicting survival outcomes. Our study provided novel ways of OC prognosis estimation and potential treatment strategy.

Abstract
In this paper, we investigate a challenging but interesting task in the research of speech emotion recognition (SER), i.e., cross-corpus SER. Unlike the conventional SER, the training (source) and testing (target) samples in cross-corpus SER come from different speech corpora, which results in a feature distribution mismatch between them. Hence, the performance of most existing SER methods may sharply decrease. To cope with this problem, we propose a simple yet effective deep transfer learning method called progressive distribution adapted neural networks (PDAN). PDAN employs convolutional neural networks (CNN) as the backbone and the speech spectrum as the inputs to achieve an end-to-end learning framework. More importantly, its basic idea for solving cross-corpus SER is very straightforward, i.e., enhancing the backbone's corpus invariant feature learning ability by incorporating a progressive distribution adapted regularization term into the original loss function to guide the network training. To evaluate the proposed PDAN, extensive cross-corpus SER experiments on speech emotion corpora including EmoDB, eNTERFACE, and CASIA are conducted. Experimental results showed that the proposed PDAN outperforms most well-performing deep and subspace transfer learning methods in dealing with the cross-corpus SER tasks.

Abstract
Cysteine proteinases (Cyps) play vital roles in many biological processes, including physiological and pathological reactions. In the present study, we cloned a full cDNA of SlCyp, encoding a 344-amino-acid protein from Spodoptera litura. The putative amino acid sequence shared >75% identity with Cyps from other insects. A phylogenetic analysis revealed that SlCyp is closely related to other known lepidopteran Cyps. Real-time PCR and Western blotting analyses showed that SlCyp is induced by Nomuraea rileyi infection in all the tissues tested. The strongest SlCyp mRNA and protein expression was found in haemocytes, followed by the fat bodies, of unchallenged and N. rileyi-challenged S. litura. A time-course analysis showed that SlCyp mRNA and protein expression levels were upregulated in the haemocytes and fat bodies by N. rileyi infection. Upon N. rileyi infection, the proteolytic activities of SlCyp were also significantly higher in the haemolymph than in normal or phosphate-buffered-saline-challenged controls. These results suggest that SlCyp plays an important role in the innate immunity of S. litura in response to N. rileyi. SlCyp mRNA and protein expression and activities were also elevated during sixth-instar moulting and metamorphosis. Knocking down SlCyp transcripts with double-stranded RNA interference caused prepupal, pupal, and adult phenotypic changes, and SlCyp-silenced mutant larvae displayed a significantly lower survival rate after N. rileyi infection. These facts suggest that SlCyp plays a significant role in resisting N. rileyi infection and an essential role in larval development. Our data should facilitate the development of techniques for S. litura control.

Abstract
WHAT IS KNOWN AND OBJECTIVE The use of extemporaneously prepared admixtures of drugs must be supported by documentation of their chemical stability. The objective was to assess the physical compatibility and the chemical stability of doxofylline with phentolamine mesilate in 0.9% sodium chloride or 5% dextrose injection for intravenous infusion. METHODS Total volumes of 20 and 1 mL of doxofylline solution and phentolamine mesilate solution, respectively, were added to 250 mL polyolefin bags containing 5% dextrose injection or 0.9% sodium chloride injection. Bags were stored for 24 h at 20-25 °C. Chemical compatibility was measures with high-performance liquid chromatography, and physical compatibility was determined visually. RESULTS The samples were clear and colourless when viewed in normal fluorescent room light. The pH value and particulate content of the admixtures exhibited little change. The retentions of the initial concentration of doxofylline and phentolamine mesilate in the admixtures were within 97-105%. Doxofylline and phentolamine mesilate were stable in 5% dextrose injection or in 0.9% sodium chloride for up to 24 h at 20-25 °C. WHAT IS NEW AND CONCLUSION Doxofylline and phentolamine mesilate mixed in both 5% dextrose injection and 0.9% sodium chloride injection in 250 mL multilayer polyolefin bags at concentrations of 0.74 mg/mL and 36.9 μg/mL, respectively, were stable for up to 24 h at 20-25 °C.

Abstract
OBJECTIVES Acute lung injury and inflammation can occur after hepatic ischemia/reperfusion (I/R). Little is known regarding the possible role of nitric oxide synthase expression in this complex type of lung injury. METHODS Real-time polymerase chain reactions and immunohistochemistry were used to assess the mRNA and protein expression of eNOS and iNOS in lung tissue after I/R challenge to the liver. Ischemia was induced by clamping the hepatic artery and portal vein for 40 minutes. After flow was restored, the liver was reperfused for 300 minutes. Blood samples were collected to assay three inflammatory parameters: tumor necrosis factor (TNF)-alpha, hydroxyl radicals, and NO. Lung lavage samples were assayed for protein and myeloperoxidase. The expression of eNOS and iNOS in lung tissues (n = 3) was also evaluated after I/R challenge to the liver. The iNOS inhibitor aminoguanidine was also tested in this I/R model. RESULTS Reperfusion of the liver produced increased blood concentrations of TNF, hydroxyl radicals, and NO (P < .001; n = 8). Bronchial lavage fluids showed higher levels of protein and myeloperoxidase in the I/R than in the sham-treated group (P < .01). eNOS expression was down-regulated and iNOS expression up-regulated in I/R lung tissues (n = 3). The iNOS inhibitor aminoguanidine (10 mg/kg) significantly attenuated the lung injury. CONCLUSIONS I/R injury to the liver induced lung injury involving systemic inflammatory responses and iNOS expression. Administration of aminoguanidine significantly attenuated the injury, suggesting that iNOS expression may play a critical role in lung injury induced by I/R of the liver.

Abstract
OBJECTIVE To determine the benefit of inhaled high dose budesonide combined with terbutaline in patients with severe asthma at high altitude. METHODS 42 patients with severe asthma at high altitude were assigned in a randomized, double-blind fashion to receive either budesonide combined with terbutaline (budesonide group, 21 cases) or terbutaline with placebo (control group, 21 cases). Both groups received terbutaline delivered by a metered-dose inhaler in a dose of 2.5 mg. Budesonide delivered by a metered-dose inhaler in 1.2 mg in budesonide group and placebo managed by a specially prepared metered-dose inhaler in control group were administered after terbutaline treatment above procedures. Repeated once after 10 min. Before and after therapy, the scores of the activity of accessory respiratory muscles, dyspnea, wheezing (clinical index) and lung function were documented. RESULTS At 1, 2, 4, 6 h after therapy, FEV1% [(43 +/- +/- 5)%, (50 +/- 5)%, (57 +/- 5)%, (67 +/- 6)%], PEF% [(47 +/- 5)%, (55 +/- 6)%, (62 +/- 7)%, (69 +/- 7)%], clinical index (5.1 +/- 0.8, 4.3 +/- 0.6, 3.5 +/- 0.6, 2.5 +/- 0.4) in budesonide group and FEV1% [(42 +/- 5)%, (44 +/- 5)%, (45 +/- 5)%, (45 +/- 5)%], PFE% [(46 +/- 5)%, (47 +/- 5)%, (49 +/- 6)%, (49 +/- 6)%], clinical index (5.3 +/- 0.7, 5.0 +/- 0.5, 4.9 +/- 0.7, 4.8 +/- 0.7) in control group were difference markedly compared with before therapy [budesonide group was (35 +/- 5)%, (38 +/- 5)%, 8.3 +/- 1.0, and control group was (33 +/- 5)%, (38 +/- 5)%, 8.3 +/- 1.1, respectively], all (P < 0.01). CONCLUSIONS High dose of inhaled budesonide combined with terbutaline should be an effective therapy for patients with severe asthma at high altitude. Budesonide inhaled in high dose produces therapeutic effects as soon as 2 h after therapy.

Abstract
This paper shows the measurement of high-resolution fluorescence excitation spectrum of uncooled NO2 in the range of 589.3-594 nm. The 11 vibronic bands approximately 120 lines in this region were rotationally assigned. The analysis shows that these lines are mainly arise from the parallel transition of 2B2(K' = 0)-->2A2(K" = 0). The spectroscopic parameters describing these bands are obtained. The discussion is given to the complexity of spectrum structure.
