ABSTRACT
Objective:To study the application value of flexible endoscopic examination of swallowing(FEES) for the aspiration screening, the diagnosis of dysphagia and evaluation of the therapeutic effectin acute stroke patients with dysphagia.Methods:Three hundred and seventy-three patients with acute stroke who hospitalized from October 2015 to January 2020 in Dalian Municipal Central Hospital Affiliated of Dalian Medical University and underwent FEES for analyzing the characteristic performance were enrolled, and 11 cases of them were examined by video fluoroscopic swallowing study (VFSS). The results of the reliability of diagnosis dysphagia of the two methods were compared. The results of FEES for assessing the recovery effect after treatment were evaluated.Results:In 373 patients, the FEES revealed 268 cases(71.85%) of aspiration (99 cases) were recessive aspiration, which was better than that in water swallow test (50.94%, 190/373). Patients with potential cricopharyngeus achalasia got the same results through both of VFSS and FEES. FEES could provide more positive indicators and guide clinical rehabilitation treatment and objective assessment of rehabilitation effectiveness.Conclusions:Acute stroke patients with dysphagia have characteristic laryngeal performance. FEES is simple to operate and has high application value.
ABSTRACT
Objective@#To understand the current situation of intimate partner violence (IPV) among young students in Chengdu and its relationship with emotion regulation self-efficacy,and to provide a reference for conducting the education on close relationship.@*Methods@#Totally 1 041 young students with love experience in Chengdu were selected by by stratified cluster random sampling to explore potentional factors related to IPV.@*Results@#The incidence of IPV perpetration among young students with love experience was as high as 69.6% and the incidence of IPV victimization was 62.2%. Young students had committed(65.4%) or been subjected(64.0%) to more than three intimate partner violence. 59.92% young students were both perpetrators and victims of IPV. Multiple Logistic regression analysis showed that compared with young female students, young male students were not prone to commit violence in intimate relationships(OR=0.59), but may become victims of IPV(OR=1.91). More than half a year in love(OR=1.70), cohabitation(OR=2.47), bullying by peers (OR=1.54) and interference by parents (OR=1.63) were risk factors for IPV perpetration. Among them, more than half a year in love (OR=1.51) and cohabitants (OR=2.52) were positively associated with IPV victimization. The efficacy of managing negative emotions was a negatively associated with IPV perpetration (OR=0.96) and victimization(OR=0.97)(P<0.05).@*Conclusion@#The phenomenon of intimate partner violence among young students is more common, which is closely related to the rearing style of young students, peer relationship, love relationship and the ability to manage negative emotions, which should be paid attention to.

OBJECTIVE@#To investigate the therapeutic efficacy of coblation-assisting uvulopalatopharyngoplasty (CAUPPP) combining with coblation-channeling of the tongue (CCT) for patients with severe obstructive sleep apnea-hypopnea syndrome (OSAHS).@*METHOD@#A retrospective analysis was made on patients with severe OSAHS treated by CAUPPP combining with CCT. The adult with severe OSAHS were involved in the study and the apnea-hypopnea index (AHI) were beyond 40/h and lowest arterial oxygen saturation (LSaO2) were under or equal to 80%. Surgical approach: The UPPP was performed to decrease the size of soft palate with coblation and coblation-channeling in the soft palate and decrease the size of tongue by CCT. All patients were followed up for 6 to 12 months and underwent polysomnography (PSG).@*RESULT@#Subjective symptoms of patients improved more significantly than that of preoperation. The function of soft palate is normal without significant nasopharyngeal regurgitation. Compared with the preoperative data, AHI values were significantly decreased (P<0.01) and the lowest oxygen saturations increased significantly (P<0.01) and the effective rate was 91.7%.@*CONCLUSION@#There are usually multiple obstruction levels in patients with severe OSAHS and the traditional surgical treatment is not ideal. This study demonstrated that with the assistance of coblation, combining CAUPPP with CCT for patients with severe OSAHS is an effective surgical method. It has less blood loss, minimally invasive, retained the normal function of the soft palate, etc., should be widely applied.
