Objective To examine the precise function of influenza A virus target genes(IATGs)in malignancy. Methods Using multi-omics data from the TCGA and TCPA datasets,33 tumor types were evaluated for IATGs.IATG expression in cancer cells was analyzed using transcriptome analysis.Copy number variation(CNV)was assessed using GISTICS 2.0.Spearman's analysis was used to correlate mRNA expression with methylation levels.GSEA was used for the enrichment analysis.Pearson's correlation analysis was used to examine the association between IATG mRNA expression and IC50.The ImmuCellAI algorithm was used to calculate the infiltration scores of 24 immune cell types. Results In 13 solid tumors,IATG mRNA levels were atypically expressed.Except for UCS,UVM,KICH,PCPG,THCA,CHOL,LAMI,and MESO,most cancers contained somatic IATG mutations.The main types of CNVs in IATGs are heterozygous amplifications and deletions.In most tumors,IATG mRNA expression is adversely associated with methylation.RT-PCR demonstrated that EGFR,ANXA5,CACNA1C,CD209,UVRAG were upregulated and CLEC4M was downregulated in KIRC cell lines,consistent with the TCGA and GTEx data. Conclusion Genomic changes and clinical characteristics of IATGs were identified,which may offer fresh perspectives linking the influenza A virus to cancer.

Dioscoreae Rhizoma formula granules are made from decoction pieces by decocting, extracting, separating, concentrating, drying and granulating, which have the advantages of simple dispensing, convenient use and easy to take without decoction. However, because Dioscoreae Rhizoma is rich in starch and mucus components, its extract powder and formula granules are poorly soluble and difficult to dissolve or disperse completely within 5 min, and the insoluble material is difficult to dissolve completely even after 24 h in water, which affects the quality evaluation of the formula granules and medication psychology of patients. Therefore, by studying the dissolution process and mechanism of Dioscoreae Rhizoma extract and its formula granules, it was found that the special chemical composition of Dioscoreae Rhizoma, the denaturation of starch and its compounding with protein and other substances during the high temperature extraction process, and the contraction of coating membrane during the spray drying process were combined to form the special microstructure of coating membrane covering starch granules, and it is the root cause of poor solubility of Dioscoreae Rhizoma formula granules. Based on the research on the structure, property and function of the powder, this paper proposed a technical strategy to improve the solubility of Dioscoreae Rhizoma formula granules by powder modification process, and experimentally demonstrated that the modified Dioscoreae Rhizoma formula granules could completely dissolve within 2 min, which solved the technical problem and could provide reference for the improvement of solubility of other similar varieties, and promote the high-quality development of traditional Chinese medicine formula granule industry.

Objective:To observe any effect of a half palm ankle-foot orthosis and a hollow-heel ankle-foot orthosis on the gait of stroke survivors.Methods:The walking of twenty-five stroke survivors was quantified using a gait analysis system. They walked barefoot, wearing a half palm ankle-foot orthosis and wearing a hollow-heel ankle-foot orthosis. Walking speed, step frequency, duration of the swing phase on the healthy and affected sides, risk of falling and Timed Up and Go (TUG) test times were recorded and analyzed.Results:The average gait frequency when wearing the hollow-heel ankle-foot orthosis was significantly faster than that in the other two conditions. The gait asymmetry coefficient was significantly different when the subjects wore the hollow-heel ankle-foot orthosis compared with walking barefoot. Compared with being barefoot, the average TUG time was significantly shorter when wearing either orthosis and the risk of falling was significantly less. The fall risk was significantly lower when wearing the hollow-heel orthosis compared to the half palm orthosis.Conclusion:Wearing either ankle-foot orthosis can significantly correct the gait of stroke survivors and lower their risk of falling, with better effect when wearing the hollow-heel ankle-foot orthosis.

In order to reveal the mechanism of silicon (Si) fertilizer in improving nitrogen (N) and phosphorus (P) nutrient availability in paddy soil, we designed a series of soil culture experiments by combining application of varying Si fertilizer concentrations with fixed N and P fertilizer concentrations. Following the recommendations of fertilizer manufacturers and local farmers, we applied Si in concentrations of 0, 5.2, 10.4, 15.6, and 20.8 μg/kg. At each concentration of added Si, the availability of soil N and P nutrients, soil microbial activity, numbers of ammonia-oxidizing bacteria and P-decomposing bacteria which means that the organic P is decomposed into inorganic nutrients which can be absorbed and utilized by plants, and urease and phosphatase activity first increased, and then decreased, as Si was added to the soil. These indicators reached their highest levels with a Si application rate of 15.6 μg/kg, showing values respectively 19.78%, 105.09%, 8.34%, 73.12%, 130.36%, 28.12%, and 20.15% higher than those of the controls. Appropriate Si application (10.4 to 15.6 µg/kg) could significantly increase the richness of the soil microbial community involved in cycling of N and P nutrients in the soil. When the Si application rate was 15.6 μg/kg, parameters for characterizing microbial abundance such as sequence numbers, operational taxonomic unit (OTU) number, and correlation indices of microbial community richness such as Chao1 index, the adaptive coherence estimator (ACE) index, Shannon index, and Simpson index all reached maximum values, with amounts increased by 14.46%, 10.01%, 23.80%, 30.54%, 0.18%, and 2.64%, respectively, compared with the control group. There is also a good correlation between N and P mineralization and addition of Si fertilizer. The correlation coefficients between the ratio of available P/total P (AP/TP) and the number of ammonia-oxidizing bacteria, AP/TP and acid phosphatase activity (AcPA), AP/TP and the Shannon index, the ratio of available N/total amount of N (AN/TN) and the number of ammoniated bacteria, and AN/TN and AcPA were 0.9290, 0.9508, 0.9202, 0.9140, and 0.9366, respectively. In summary, these results revealed that enhancement of soil microbial community structure diversity and soil microbial activity by appropriate application of Si is the key ecological mechanism by which application of Si fertilizer improves N and P nutrient availability.

Objective:To investigate the availability, prices and affordability of essential medicines in pediatric population across China, in the hope of improving rational use of medicines.Methods:A multicenter cross-sectional survey of medicine prices, availability and affordability was conducted in 17 provinces, municipalities and autonomous region across east, south-central part, west and north of China. Data on 42 medicines used in pediatric population, both original and generic, were collected in 55 public hospitals from May 26 to June 2, 2017. Availability was expressed as the percentage of hospitals with stock of the target medicine on the day of data collection,and median price ratio (MPR) was the ratio of price upon investigation to international reference. Based on national minimum daily wage, affordability represents the number of working days needed to earn the expense which covers a standard course using the target medicine. Statistical software SPSS 13.0 was applied for descriptive analysis of availability, MPR and affordability.Results:Mean Availability of original and generic medicine was 33% and 32%, with median MPR being 5.43 and 1.55. Among the 19 medicines with price information for both original and generic product, the median MPR was 7.73 and 2.04 respectively. Regarding the five medicines used to treat four common pediatric diseases (pneumonia,peptic ulcer, congenital hypothyroidism, refractory nephrotic syndrome), the affordability was 0.63 (0.16-6.17) d for generic medicine, and 1.03 (0.16-11.53) d for its original counterpart.Conclusions:The availability to both original and generic products of the 42 medicines used in pediatric population was low in China. The prices of generic medicines seem to be lower and affordability higher than those of original medicines. There is an urgent need to improve the availability and affordability of pediatric medicines.
