RESUMEN
ObjectiveTo clarify the therapeutic effect of Huashi Baidu prescription on pneumonia in mice caused by influenza A (H1N1) virus and explore its mechanism based on the transcriptome. MethodA mouse influenza viral pneumonia model was built by intranasal infection with influenza A virus, and mice were continuously administered the drug for five days, so as to investigate the general condition, lung index, viral load, pathological morphology of lung tissue, survival time, and prolongation rate of survival time of mice and clarify the therapeutic effect of Huashi Baidu prescription on influenza viral pneumonia. Transcriptome technology was used to detect the differentially expressed genes in the lung tissue of mice in the model group and the normal group, as well as the Huashi Baidu prescription group and the model group, and the potential core target of the Huashi Baidu prescription for the treatment of influenza viral pneumonia was screened. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to verify the effect of Huashi Baidu prescription on the mRNA expression level of core target genes. ResultCompared with the normal group, the lung index and viral load in the lung tissue of the model group were significantly increased (P<0.05, P<0.01). Compared with the model group, the high-dose group of Huashi Baidu prescription significantly prolonged the survival time of mice infected with influenza A virus (P<0.05) and significantly reduced the lung index value of mice (P<0.05) and the viral load of lung tissue. The high-dose, medium-dose, and low-dose groups of Huashi Baidu prescription could significantly reduce lung tissue inflammation, blood stasis, swelling, and other pathological changes in mice (P<0.05, P<0.01). Transcriptome analysis of lung tissue showed that core genes were mainly enriched in the nuclear transcription factor-κB (NF-κB) signaling pathway, interleukin-17 (IL-17) signaling pathway, cytokine-cytokine receptor interaction, and other pathways after the intervention of Huashi Baidu prescription. TRAF6, NFKBIA, CCL2, CCL7, and CXCL2 were the top five node genes with combined score values. Real-time PCR validation showed that Huashi Baidu prescription significantly downregulated the mRNA expression of key genes TRAF6 and NFKBIA in the NF-κB signaling pathway, as well as chemokines CCL2, CCL7, and CXCL2 (P<0.05, P<0.01). ConclusionHuashi Baidu prescription has a therapeutic effect on influenza viral pneumonia, possibly by inhibiting the expression of key nodes TRAF6 and NFKBIA in the NF-κB signaling pathway and that of chemokines CCL2, CCL7, and CXCL2, reducing the recruitment of inflammatory cells and viral load, and exerting anti-influenza viral pneumonia effects.
RESUMEN
Objective:To investigate the effects of bevacizumab injection on immune function and drug safety in patients with non-small-cell lung cancer (NSCLC).Methods:A total of 80 NSCLC patients admitted to Liaocheng Second People′s Hospital from August 2018 to August 2020 were selected as study subjects. They were divided into the observation group and the control group by random number table method, each group with 40 cases. The control group received routine chemotherapy and the observation group received bevacizumab injection as adjuvant therapy on the bases of control group. Short-term efficacy, serum T lymphocyte subsets, vascular endothelial growth factor (VEGF), basic fibroblast growth factor (b-FGF) levels and the incidence of adverse reactions were compared between the two groups.Results:The total effective rate and disease control rate in the observation group were significantly higher than those in the control group: 77.5%(31/40) vs. 55.0%(22/40), 92.5%(37/40) vs. 75.0%(30/40), χ2 = 4.53, 4.50, P<0.05. After the treatment, the levels of CD 3+, CD 4+, CD 8+ and CD 4+/CD 8+ in the observation group were increased ( P<0.05), while those in the control group were decreased ( P<0.05), the levels of CD 3+, CD 4+, CD 8+ and CD 4+/CD 8+ in the observation group after treatment were higher than those in the control group ( P<0.05). After the treatment, the levels of serum VEGF and b-FGF in both groups were decreased ( P<0.05), and the above indicators in the observation group were significantly lower than those in the control group ( P<0.05). The rate of adverse reactions in two groups had no significant differences ( P>0.05). Conclusions:Bevacizumab injection is safe and effective in the treatment of NSCLC, which can significantly improve the immune function of patients and reduce their serum VEGF and b-FGF levels.
RESUMEN
Heme Oxygenase-1 (HO-1) is a ubiquitously expressed enzyme which plays important functions in antioxidant, anti-inflammatory and anti-apoptosis. Recent studies have demonstrated that HO-1 also has significant antiviral properties, inhibiting the replication of some kinds of viruses such as human immunodeficiency virus (HIV), hepatitis C virus (HCV), and dengue fever virus (DFV). In this study, we evaluated the role of HO-1 in Duck Tembusu virus (DTMUV) replication in vitro. The results showed that, the mRNA expression level of HO-1 was transient up-regulated and then significantly decreased in duck embryo fibroblast (DEF) infected with DTMUV. HO-1 induction by transfection of HO-1 over-expression plasmid or treatment with cobalt protoporphyrin (CoPP), a potent HO-1 inducer, could inhibit DTMUV replication effectively. In contrast, HO-1 siRNA knockdown in DEF increased DTMUV replication, implied that HO-1 was an important cellular factor against DTMUV replication. Furthermore, we found that ferric ion (Fe3+) but not biliverdin and carbon monoxide, products of heme degradation by HO-1, mediated the HO-1-induced anti-DTMUV effect. Overall, these finding revealed that a drug induced the HO-1 signal pathway was a promising strategy for treating DTMUV infection.

Awareness of Health-Preservation management of traditional Chinese medicine (TCM) in public was investigated from June to early July in 2017 by the web of question nairein vestigation"Wenjuanxing". The result showed that 324 of 369 questionnaires were received and checked, accounting for 87.8%. In conclusion, the awareness of Health-Preservation management of TCM in public was poor, and it's important to raise the publicity of Health-Preservation management of TCM firstly in the community hospital in order to increase the awareness of people's acception.
RESUMEN
Objective To explore the effect of single-hole thoracoscopic lobectomy on patients with early non-small cell lung cancer. Methods A total of 100 patients with early non-small cell lung cancer received surgeries in our hospital from Jan 2014 to Jan 2015. They were divided into observation group(single-hole thoracoscopic lobectomy, 50 cases) and control group (three thoracoscopic lobectomy, 50 cases) according to operation modes. The operation data, postoperative recovery situations and complication rate were compared between two groups. Results All patients completed operations successfully and there were no serious complications during operations. There were no significant differences in operation time, numbers of lymph node dissection, tumor recurrence rate and survival rate in one year after operations between the two groups(P>0.05). The blood loss, length of incision, thoracic drainage, tube time, postoperative hospital stay and VAS scores at the first day after surgery in observation group were lower than those in control group(P< 0.05). The complication rate of observation group [ 20.0% (10/50) ] was lower than that of control group [40.0% (20/50) ](P<0.05). Conclusion As for patients suffered from early non-small cell lung cancer, single-hole thoracoscopic lobectomy has advantages of less bleeding, fast recovery and low complication rate.
