ABSTRACT
Objective:To explore the application of microteaching combined with hierarchical training in the teaching of standardized training for nurses in the department of endocrinology.Methods:A total of 80 nurses in the endocrinology department from February 2020 to February 2021 were selected and randomly divided into a control group and a study group, with 40 ones in each group. The control group adopted traditional teaching and the research group adopted microteaching combined with hierarchical training. After the standardized training, the two groups of nurses were subjected to theoretical assessment, practical skills assessment, clinical practice ability improvement, the satisfaction of the assessment team and inpatients with the nurses, and the incidence of adverse events during the standardized training of the two groups of nurses. SPSS 22.0 was performed for t test and chi-square test. Results:After the training, the research group's theoretical and practical skills assessment scores were better than those of the control group, with statistically significant differences ( P<0.001); the improvement of clinical practice ability of the research group was better than that of the control group, with statistical significance ( P<0.001); the satisfaction rate of nurses in the research group (assessment group and patients) was better than that of the control group, and the differences were statistically significant ( P<0.001). During the standardized training of nurses, there were statistically significant differences in the incidence of adverse events between the two groups of nurses ( χ2=5.165, P=0.023). Conclusion:The application of microteaching combined with hierarchical training can help improve the level of theoretical and practical skills of nurses in the endocrinology department, improve nurses' clinical work ability and patient satisfaction rate, effectively reduce the incidence of adverse events, and build a harmonious relationship between doctors, nurses and patients.
ABSTRACT
Objective To compare the clinical efficacy of extra vascular occlusion of low abdominal aorta and low abdominal aorta balloon occlusion in the treatment of placenta previa with placenta previa.Methods From January 2014 to July 2017,68 implantable placenta previa patients were divided into two groups,elective cesarean section of extra vascular occlusion of low abdominal aorta in 34 cases(group A)and cesarean section on the lower abdominal aorta balloon occlusion in 34 cases(group B),and observation of pregnant women was compared between surgery of two groups. Results Operation time,complications of vascular injury and thrombosis,fetal radiation exposure in group A were significantly lower than that of group B(P<0.05);two groups of patients with sensory dysfunction incidence,cesarean operation time,intraoperative blood loss,blood transfusion rate,the uterus resection rate,hospitalization time had no statistically significant difference postoperatively(P > 0.05). Conclusion Two kinds of operation can safely and effectively reduce the bleeding during the treatment of placenta previa. While group A surgery operation time is short,without intraoperative and postoperative bleeding of the puncture site,without pelvic and lower extremity arterial thrombosis,without X-ray exposure,more safety of the womb and can be popularized in clinic.
ABSTRACT
Objective:To investigate the clinical value of emergency cervical cerclage combined mesh patch suture in the treatment of cervical incompetence.Methods:From January 2011 to August 2016 in our hospital 65 cases of pregnant women with inevitable abortion,32 cases of they had carried out emergency cervical cerclage combined mesh patch suture(group A),33 cases of they had carried out cervical cerclage only(group B),The prolongation of gestation time,delivery gestational age,neonatal outcome,delivery mode and postoperative complications were compared between the two groups.Results:The operation time of A group was higher than that of group B,surgical complications of cervical laceration in group A was less than B group,the difference was statistically significant(P ＜ 0.05);there was no significant difference in the incidence of chorioamnionitis between the two groups(P＞0.05);the gestational age of group A was extended to 84.45 ±35.77 days,and the gestational age of B group was extended to 51.86 ±29.93 days,there was statistically significant difference between the two groups(P＜0.05);there was more than 28 weeks delivery in 23 cases(71.88％) in group A,and 17 cases (51.52％) in group B,the difference was statistically significant(P ＜ 0.05);there were no statistically significant differences in the delivery mode between the two groups(P ＞ 0.05);neonatal birth weight,birth Apgar 1 minutes score of group B were significantly lower than those of group A,the difference was statistically significant (P ＜0.05).Conclusions:Emergency cervical cerclage combined mesh patch suture can effectively prolong the gestational age,improve neonatal outcome,no obvious complication and has certain clinical applicative value.
ABSTRACT
Objective To investigate the effect of high mobility group box‐1(HMGB1) on the migration of vascular smooth cells (VSMCs) and the role of TLR4‐dependent PI3K/Akt pathway in the process .Methods Primary VSMCs were isolated from the thoracic aorta of male SD rats and cultured in vitro .Control group ,TLR4 siRNA transfected group ,control siRNA transfected group and PI3k inhibitor (LY294002) intervention group were stimulated by HMGB1 (0 .1-1 000 .0 ng/mL) .Expression of TLR4 mRNA was detected by RT‐PCR ,protein expression of TLR4 ,Akt ,pAkt ,PI3K were detected by Western blot .Activity of the im‐munoprecipitated PI3K enzyme was assessed in a competitive ELISA .The migration and cell viability of every groups were ob‐served .Results HMGB1 (0 .1 -1 000 .0 ng/mL) stimulated VSMCs migration in a dose‐dependent manner and incubation of VSMCs with 100 ng/mL caused a rapid migration (P< 0 .05) .At the concentrations used ,HMGB1 did not cause any cytotoxic effects (P<0 .05) .Migration of VSMCs toward HMGB1 was significantly inhibited by silencing of TLR4 (P<0 .05) .Pretreated cells with TLR4 siRNA or the PI3K inhibitor LY294002 could markedly block PI3K/Akt pathway activation and VSMCs migration mediated by HMGB1 (both P<0 .05) .Conclusion HMGB1 stimulated VSMCs migration in a dose‐dependent manner and TLR4‐dependent PI3K/Akt signaling pathway played an important role in the migration of VSMCs mediated by HMGB1 .This research indicates that TLR4‐dependent TLR4/PI3K/Akt signaling pathway could be the target in the treatment of obstructive cardiovascu‐lar disease .
