Trypanosoma cruzi relies on the enzyme trypanothione reductase, among others, to defend itself against oxidative stress. With the aim of contributing to the elucidation of the mechanism of action of quinoxaline 1,4-di-N-oxide derivatives on Trypanosoma cruzi, this study was carried out to evaluate the effect of methyl 2-amide-3-methylquinoxaline-7-carboxylate 1,4-di-N-oxide (compound M-8) on the expression of the trypanothione reductase gene in an in vitro model on Trypanosoma cruzi epimastigotes of the CL-Brener strain. The results show that compound M-8 does not cause a significant effect on the trypanothione reductase gene, suggesting a mechanism of action not related to oxidative stress. 2019-05-27T00:00:00Z http://localhost:80/xmlui/handle/123456789/14720 Title: Effect of peripherally inserted central catheter (PICC) parenteral nutrition on immune function and nutritional support after radical gastrectomy for gastric cancer Authors: Zhang, Jixun; Si, Xianke; Li, Wei; Yang, Jiahua; Cao, Yijun Abstract: Objective of the present study was to investigate the effects of peripherally inserted central catheter (PICC) parenteral nutrition support on immune function and nutritional support in patients undergoing radical gastrectomy for gastric cancer. 140 patients who underwent radical gastrectomy for gastric cancer were selected as participants and were divided into study group and the control group by random number table, with 70 cases in each group. Patients in the two groups underwent standard gastrectomy under general anesthesia by the same group of doctors. The study group received postoperative PICC catheter parenteral nutrition, and the control group received central venous catheter (CVC) nutrition support. Comparative study was done using t test and Chi-square test. The serum levels of ALB, TFN, PA, Hb, CD4+ , CD8+ , CD4+ /CD8+ , IgA, IgG, IgM and CD3+ in the two groups were observed before and after treatment, and the postoperative complications of the two groups were compared. After treatment, the levels of ALB, TFN, PA and Hb in the two groups were significantly increased (P<0.05). Levels of CD3+ , CD4+ , CD4+ /CD8+ , IgA, IgG and IgM also amplified significantly after treatment in both the groups, while CD8+ decreased significantly (P<0.05). What’s more, the improvement degree of the study group was significantly greater than that of the control group (P<0.05). The time of drawing drainage tube, recovering intestinal function, getting off bed and the length of hospital stay in the study group were significantly shorter than those in the control group (P<0.05). The incidence of postoperative complications in the study group and control group were 8.6% (6/70 cases) and 11.4% (8/70 cases) respectively, and there was no significant difference (P>0.05). PICC catheter parenteral nutrition support and improve the nutritional status of patients, it was proved a safe and effective nutritional support which improve the cellular immune function and accelerated the recovery of gastrointestinal function. 2019-05-26T00:00:00Z http://localhost:80/xmlui/handle/123456789/14718 Title: Effects of dexamethasone combined with ambroxol hydrochloride on T-Cell subsets and hearing in patients with secretory otitis media Authors: Xiaorong, Dong; Li, Ma; Xuefeng, Liu; Jian, He Abstract: The aim of the study was to investigate the effect of dexamethasone combined with ambroxol hydrochloride on T cell subsets and hearing in patients with secretory otitis media. Eighty-six cases of patients with secretory otitis media admitted to “Gansu Provincal Hospital, Lanzhou, China” from September 2016 to September 2018 were regarded as subjects of the study. The patients were divided in two groups according to the digital table method. Among them, the control group was treated with ambroxol hydrochloride, while the study group was treated with dexamethasone combined with ambroxol hydrochloride. The clinical efficacy, T cytokines before and after treatment, auditory threshold and middle ear resonance frequency were observed and compared between the two groups of the patients. SPSS 18.0 software was used to statistically analyze the data. The therapeutic efficacy of the study group was better than that of the control group and the levels of CD4+ , CD4+ /CD8+ after treatment of the study group were higher than that of the control group (P<0.05), while the content of CD8+ in the study group was lower than that in the control group (P<0.05). In addition, the auditory threshold of the study group was lower than that of the control group (P<0.05), whereas the middle ear resonance frequency was higher than that of the control group (P<0.05). The application of dexamethasone combined with ambroxol hydrochloride improved the clinical symptoms and restored hearing in the clinical treatment of patients with secretory otitis media and the therapeutic efficacy was ideal. 2019-05-25T00:00:00Z http://localhost:80/xmlui/handle/123456789/14716 Title: Clinical study of external application of liuhe dan in the treatment of anal edge edema after mixed hemorrhoid operation Authors: Wu, Jing; Lu, Wenzhu; Yu, Keqiang; Liu, Hong Abstract: To observe the therapeutic efficacy of external application of Liuhe Dan in the treatment of anal edge edema after mixed hemorrhoid operation. A total of 160 patients who had been treated for lotion anal edge edema from January 2016 to August 2018 were enrolled research ojbects. They were divided into control group accepting routine nursing methods (80 cases) and research group accepting external application of Liuhe Dan (80 cases). The therapeutic efficacies of two groups were compared. The anal edge edema score and wound pain score of the research group were significantly lower than those of the control group (p<0.05). Meanwhile, the length of hospital stay and wound healing time of the research group were significantly shorter than those of the control group (p<0.05). External application of Liuhe Dan in the treatment of anal edge edema after mixed hemorrhoid operation could significantly improve the therapeutic efficacy and alleviate the patient’s pain, which is of great application value. 2019-05-24T00:00:00Z
