The covered stents has been increasingly used in the prevention and treatment of the restenosis of the transjugular intrahepatic portosystemic shunt (TIPS), outcoming with obvious achievement, Viatorr stent-graft has been proved to be more efficient for the improvement of shunt patency. The purpose of the article is to review the formation, the character, the application and efficacy of the covered stents used in TIPS. With the improvement of covered stents, TIPS will regain its lost popularity in the treatment of portal hypertension.

Objective:The characteristics and prognosis of ear fullness feeling in patients with all-frequency sudden deafness were explored.Method:104 patients (104 ears) with unilateral all-frequency sudden deafness were collected in study from June 2015 to March 2019, including 50 males and 54 females, the mean age ranged from 23-65 years, and the disease duration ranged from 1-9 days. Of those, 56 patients accompanied with the feeling of ear fullness (FEF) were enrolled into'the ear fullness group′, and 48 patients without FEF were included in'the without ear fullness group′. Patients′ treatment strategy followed the Chinese Medical Association Guidelines for the diagnosis and treatment of sudden deafness (2015). Moreover, VAS scale scores and subjective grading of FEF were acquired in patients with FEF. We analyzed the clinical characteristics and prognosis of FEF with SPSS 23.0 software.Results:There were no differences between the two groups in terms of age, gender, duration of disease, the side of deaf ear, degree of hearing loss, and auditory brainstem evoked potential results (age, t=1.566; gender,χ 2=0.001; duration, t=0.057; side,χ 2=0.033; degree of hearing loss Z=-0.180; ABR,χ 2=0.001;all P>0.05) . There was a positive correlation between the subjective grading of FEF and the degree of hearing loss in patients with FEF ( r=0.599, P<0.001) . The total rate of hearing improvement following one month of treatments in patients with FEF vs with no FEF was 35/56(62.5%) vs 28/48(58.3%) ( Z=-0.641, P=0.521). After one month of treatment, the total effective rate of FEF was 94.6%(53/56), and the improvement of FEF had nothing to improvement of hearing ( r=0.040, P=0.769) . Conclusions:The degree of hearing loss is positively correlated with the degree of FEF in patients with all-frequency sudden deafness. Hearing recovery is not related to FEF. The recovery effect of FEF is good, and has no correlation with hearing recovery.

Objective The purpose of writing the"Expert consensus on the prevention and control of intracranial hypertension in adult critical illness"(here in after referred to as the"Consensus")aimed to standardize the nursing work related to the prevention and control of elevated intracranial pressure in adult critical illness,and prevent the occurrence of complications such as cerebral herniation.Methods Guided by evidence-based practice,domestic and foreign databases were searched for guidelines,expert consensuses,systematic evaluation,evidence summaries,and original research related to increased intracranial pressure.The search period is from database establishment to March 2024.The high-quality evidence and suggestions in the field was evaluated,extracted,and summarized to form a preliminary consensus.27 experts were invited to conduct 2 rounds of expert inquiry and 8 experts were invited to conduct 2 expert discussion meetings,to revise and improve the content of the initial draft,and to ultimately form a final consensus.Results The effective response rates for both rounds of inquiry questionnaires were 100％,with expert authority coefficients of 0.884,judgment coefficients of 0.964,and familiarity levels of 0.804.The Kendall harmony coefficients for 2 rounds of inquiry were 0.107 and 0.083(P＜0.01),respectively.The consensus includes 4 aspects,including identification,monitoring,prevention and control strategies,emergency treatment and care for increased intracranial pressure.Conclusion This"Consensus"has strong scientific validity and can provide reference basis for nurses to carry out prevention and control of intracranial pressure increase.
