RESUMO
Objective To investigate the application effect of electromagnetic navigation bedside nasoenteral intubation technology in elderly bedridden patients.Methods A total of 92 elderly patients with tube feeding in bed in a tertiary A hospital in Beijing from June 2021 to December 2022 were selected by convenience sampling method,and they were divided into an experimental group and a control group with 46 patients in each group by random number table method.The experimental group adopted the electromagnetic navigation bedside nasoenteral catheterization technique and the control group adopted the blind catheterization method.The total success rate of catheterization,the success rate of the first catheterization,the time taken for catheterization,the proportion of catheter tip reaching jejunum,and the incidence of catheter-related complications were compared between the 2 groups.Results There were no shedding cases in both groups.The success rate of total catheterization was 95.7％in the experimental group and 80.4％in the control group.The success rate of first catheterization was 95.7％in the experimental group and 71.7％in the control group.The time taken for catheterization was(12.37±4.19)min in the experimental group and(19.22±5.48)min in the control group.The proportion of catheter tip reaching the jejunum was 60.9％in the experimental group and 28.3％in the control group.The above data were compared between the 2 groups,and the differences were statistically significant(P＜0.05).In terms of the incidence of catheter-related complications,the incidence of epistaxis in the experimental group was 6.5％and it was 21.7％in the control group,and the difference was statistically significant(P=0.036).The positive rate of fecal occult blood test was 2.2％in the experimental group and 17.4％in the control group,and the difference was statistically significant(P=0.030).There was no significant difference in the incidence of nausea,vomiting and abdominal distension between the 2 groups(P＞0.05).No serious complications such as catheter ectopic placement,pneumothorax and perforation occurred in the 2 groups.Conclusion The application of electromagnetic navigation bedside nasoenteral intubation technology for elderly bedridden patients has a high success rate and takes a short time,which can improve the proportion of catheter tip reaching the jejunum and reduce the incidence of epistaxis and fecal occult blood test.
RESUMO
Objective:To study on the levels of CXCL8 and its receptors (CXCR1 and CXCR2) in peripheral blood neutrophils of the patients with chronic hepatitis B.Methods:The neutrophils were isolated and purified by neutrophil isolation medium,and the loads of HBV-DNA in neutrophils were detected by PCR,and the levels of HBeAg in serum were measured by ELISA.The patients were divided into different groups according to the detective results so that the expressions of CXCL8 and its receptors ( CXCR1,CXCR2) in neutrophils were detected by the methods of streptavidin-biotin complex ( SABC ) immunocytochemistry stain.Results:The data of SABC immunocytochemical stain showed that the positive color of CXCL8 was mainly located in the cytoplasm of PMNs.However,the most positive color of CXCR1and CXCR2 was mainly expressed in the cytoplasm and cell membrane.Interestingly,the deeper immune coloring of CXCL8 and CXCR1, and relatively shallow immune coloring of CXCR2 were explored in the group with positive of HBeAg.The similar detective results also had been found in the cases with positive of HBV DNA in neutrophils.Compared with the normal control group,the levels of CXCL8 and CXCR1 in the patients were significantly increased ( P0.05).Conclusion:After neutrophils occult infected by HBV,not only the secretion of CXCL8 can be promoted, but also the expression of CXCR1 will be further increased.The data of immunohistochemical staining have been shown that the color degree of CXCL8 and its receptors ( CXCR1, CXCR2 ) are positive correlation to the level of HBeAg and the loads of HBV DNA.More PMNs can be chemotactic attraction to lesion so as to participate in the local inflammatory injury and tissue repair via the interactive pathway of the high expression of CXCR1 on surface of neutrophils with CXCL8.

RESUMO
The therapeutic effect and laboratory findings in 137 case of acute cerebral infarction treated with Propylene Glycol Mannurate Sulfate (PGMS) were analysed. The positive therapeutic response to PGMS in the treated group was obtained to 95. 6% and 70. 1%,and was better than that of the controls ( P
RESUMO
We analysed the therapeutic effect and laboratory findings in the patients of a-cute cerebral infarction treated with PGMS and PSS. The results show that the efficient rate of PGMS group was obtained to 95. 6% and 70. l%,and was better than that of PSS group, but there was no statistic significance. The laboratory findings show the i both of them had the effect of anticogau ant and decreasing blood viscosity and serum co tents of lipids. But PGMS had a slight anticoagulant effect and could obviously decrease olood viscosity and serum contents of lipids. here was no side effects in the PGMS group. So PGMS is considered to be a prospective drug for treating acute cerebral infarction.
