Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

Objective:To explore the effectiveness of immersive virtual reality (VR)-guided core stability-assisted training in improving the balance of ischemic stroke survivors.Methods:Sixty-six hemiplegic ischemic stroke survivors were randomly divided into a conventional rehabilitation training group (CON) of 32 and an immersive VR-guided core stability-assisted training group (VR-TOT) of 34. In addition to basic internal medical treatment, the CON group underwent conventional rehabilitation therapy, while the VR-TOT group received VR-guided core stability-assisted training. Before and after 4 weeks of the treatments, the subjects′ balance was evaluated using the Fugl-Meyer balance scale. A three-dimensional force platform was used to collect the sway amplitude, sway speed, peripheral area and total trajectory length of the center of pressure COP of the bilateral plantar in the left-right and anterior-posterior directions while the subjects stood with the eyes open and closed.Results:After the treatments, the average Fugl-Meyer balance scores of both groups had improved significantly. In the eyes-open condition, after the treatment, there was a significant decrease in the average COP sway amplitude in the anteroposterior direction on the hemiplegic side among the CON group, as well as in both the mediolateral and anteroposterior directions on both sides in the VR-TOT group. The sway velocity in the anteroposterior direction on the hemiplegic side had decreased significantly in both groups, and the sway velocity in both the mediolateral and anteroposterior directions on the non-hemiplegic side had also decreased significantly. In the CON group the peripheral area on the non-hemiplegic side had decreased and the total trajectory length had shortened significantly. In the VR-TOT group there were significant decreases in the peripheral area on both sides and in the total trajectory length on both sides. Comparing the two groups after treatment, the peripheral area on the hemiplegic side in the VR-TOT group was significantly smaller. In the eyes-closed condition, the sway amplitude of the COP on the hemiplegic side in the anteroposterior direction and on the non-hemiplegic side in both the mediolateral and anteroposterior directions had decreased significantly in the VR-TOT group after the treatment. The average sway velocity had decreased significantly in the anteroposterior direction on the non-hemiplegic side in the CON group. In the VR-TOT group this was observed in the anteroposterior direction on the hemiplegic side and in both the mediolateral and anteroposterior directions on the healthy side. In the CON group the average peripheral area of the COP on the hemiplegic side had decreased, and the total trajectory length had shortened, both significantly. In the VR-TOT group, the peripheral area on the non-hemiplegic side had decreased significantly as well.Conclusions:Core stability-assisted training based on immersive virtual reality can effectively improve the balance of ischemic stroke survivors. It shows promise for clinical application.

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.
