After three years of practice, ICU nursing management mode has achieved the goal of participating in shared governance, enhancing nurses′ perception of patient safety culture and improving the level of work engagement.

Objective:To analyze characteristics and trend of publications in digestive endoscopy quality control from 2010 to 2021.Methods:The literature on digestive endoscopy quality control from 2010 to 2021 were searched through the Web of Science core collection with the method of bibliometrics. The year of publication, journal name, country, main researchers, institutions and citations were analyzed by Web of Science. Then, the downloaded data were imported into VOSviewer for co-occurrence network analysis of the country, keywords and citations.Results:A total of 3 283 English papers on digestive endoscopy quality control were included. The number of papers from China and other countries showed an upward trend, and citations as well from 2010 to 2021. The publications were mainly from the United States (1 209, 36.8%), the United Kingdom (325, 9.9%), and China (324, 9.9%). The journal with the largest number of publications in this category was Gastrointest Endosc (241, 7.3%). The U.S. Department of Veterans Affairs had 175 publications, ranking the first among all institutions. Research topics were focused on colonoscopy, adenoma detection rate, and artificial intelligence. Conclusion:The research in digestive endoscopy quality control is booming, and the research activity is gradually increasing. Chinese academic influence in this field still needs to be further improved.

Objective:To investigate the factors affecting postoperative short-term improvement of consciousness level in patients with prolonged disorders of consciousness after severe traumatic brain injury (sTBI).Methods:A case-control study was conducted to analyze the clinical data of 55 patients with prolonged disorders of consciousness after sTBI admitted to Beijing Tiantan Hospital Affiliated to Capital Medical University and Seventh Medical Center of PLA General Hospital from September 2021 to September 2022. There were 33 males and 22 females, with the age range of 13-68 years [(43.0±15.5)years]. All patients were assessed for the consciousness level using the coma recovery scale-revision (CRS-R) preoperatively and within 48 hours postoperatively. A total of 33 patients were observed in vegetative state and 22 in minimally conscious state preoperatively. The consciousness level was found to be improved in 26 patients (consciousness- improved group), but not improved in the remaining 29 patients (consciousness-unimproved group). Indicators were documented including gender, age, cause of injury, Glasgow coma score (GCS) on admission, course of injury, preoperative consciousness level, operation mode, operation time, intraoperative fluid replenishment, intraoperative urine volume, intraoperative bleeding volume, American Society of Anesthesiologists grade, analgesic regimen and sedation maintenance drugs. A univariate analysis was conducted first to assess those indicators′ correlation with postoperative short-term improvement of consciousness level in patients with prolonged disorders of consciousness after sTBI. Multivariate Logistic regression analysis was then used to determine the independent risk factors for their postoperative short-term improvement of consciousness level.Results:Univariate analysis showed that GCS on admission, course of injury, preoperative consciousness level and analgesic regimen were correlated with short-term improvement of postoperative consciousness level in patients with prolonged disorders of consciousness after sTBI (all P<0.05), whereas gender, age, cause of injury, operation mode, operation time, intraoperative fluid replenishment, intraoperative urine volume, intraoperative bleeding volume, American Society of Anesthesiologists grade and sedation maintenance drugs showed no relation to the improvement of postoperative consciousness level (all P>0.05). Multivariate Logistic regression analysis showed that the GCS ≥7 points on admission ( OR=0.06, 95% CI 0.01, 0.36, P<0.01), preoperative minimally conscious state ( OR=0.09, 95% CI 0.02, 0.40, P<0.01) and intraoperative use of Sufentanil combined with Remifentanil ( OR=0.07, 95% CI 0.01, 0.43, P<0.01) were significantly correlated with postoperative improvement of consciousness level. Conclusion:The GCS on admission (≥7 points), preoperative minimally conscious state and intraoperative use of Sufentanil combined with Remifentanil are independent risk factors affecting short-term postoperative improvement of consciousness level in patients with prolonged disorders of consciousness after sTBI.

Objective:To evaluate the relationship between the mechanism of propofol inhibiting carotid sinus baroreflex (CSR) and GluR2 subunit-containing AMPA receptors in the nucleus ambiguus of rats with type 2 diabetes mellitus (T2DM).Methods:SPF healthy male Sprague-Dawley rats, aged 3 weeks, were selected and fed a high glucose and high fat diet for 6 weeks, and then streptozotocin 30 mg/kg was intraperitoneally injected to prepare a T2DM model of rats. Twenty-four T2DM rats were divided into 4 groups ( n=6 each) using a random number table method: diabetes mellitus-normal saline group (DN group), diabetes mellitus-propofol group (DP group), AMPA receptor agonist-normal saline group (AN group), and AMPA receptor agonist-propofol group (AP group). Another 12 normal rats were selected and divided into 2 groups ( n=6 each) using a random number table method: normal-normal saline group (NN group) and normal-propofol group (NP group). AMPA receptor agonist mibamitor 1 nmol/L (50 nl) was injected into the nucleus ambiguus using a micropipette at 30 min before perfusion of isolated carotid sinus in AN and AP groups. Propofol 45 mg·kg -11·h -1 was infused for 2 h via the femoral vein in NP group, DP group and AP group, and the equal volume of normal saline was given instead in the other groups. A model for perfusing isolated carotid sinus was developed at 20 min after infusion of propofol or normal saline, the intracarotid sinus pressure (ISP)-mean arterial blood pressure (MAP) curve was drawn, and CSR parameters such as maximum slope (PS), threshold pressure (TP), saturation pressure (SP), equilibrium pressure (EP), maximum decrease in MAP reflexivity (RD), and carotid sinus baroreceptor operating range (OR) were recorded. Brain tissues were taken at the end of perfusion, and the expression of GluR2 subunit in the nucleus ambiguus was detected by Western blot and immunofluorescence. Results:Compared with the corresponding normal saline groups (NN group, DN group, AN group), PS and RD were significantly decreased, TP, SP and OR were increased ( P<0.05), and the ISP-MAP curve was shifted upward in propofol groups (NP group, DP group, AP group), the expression of GluR2 subunit in the nucleus ambiguus was down-regulated in NP and DP groups ( P<0.05), and no significant change was found in the expression of GluR2 subunit in the nucleus ambiguus in AP group ( P>0.05). Compared with NP group, PS and RD were significantly decreased, TP, SP and OR were increased ( P<0.05), the ISP-MAP curve was shifted upward, and the expression of GluR2 subunit in the nucleus ambiguus was down-regulated in DP group ( P<0.05). Compared with DP group, PS and RD were significantly increased, TP, SP and OR were decreased ( P<0.05), the ISP-MAP curve was shifted downward, and the expression of GluR2 subunit in the nucleus ambiguus was up-regulated in AP group ( P<0.05). Conclusions:The mechanism by which propofol inhibits CSR may be related to down-regulation of the expression of GluR2 subunits-containing AMPA receptors in the nucleus ambiguus of rats with T2DM.

Objective:To translate the Nurse Delirium Care Competency Scale (NDCCS) into Chinese and test the validity and reliability of Chinese version of NDCCS among ICU nurses.Methods:According to Brislin translation model, the Chinese version of NDCCS was developed by forward translation, back translation, cross-cultural adaptation and pre-survey. From October to December of 2023, 338 ICU nurses from Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were selected by cross-sectional survey to test the reliability and validity of Chinese version of NDCCS.Results:A total of 329 valid questionnaires were collected. There were 50 males and 279 females, aged 20-53 years old. The Chinese version of NDCCS included 6 dimensions and 27 items. The scale-level content validity value was 0.985, and the item-level content validity value was 0.800-1.000. Exploratory factor analysis showed a six-factor structure, the cumulative variance contribution rate was 75.700%, the Cronbach′s α coefficients of the scale amount table were 0.952, and the Cronbach′s α coefficients of the dimensions were 0.811- 0.936,and the retest reliability was 0.932.Conclusions:The Chinese version of the NDCCS has good reliability and validity, and it is suitable for assessing the delirium care competence of ICU nurses in China.

This corrects the article “Analysis of Tau Protein Expression in Predicting Pathological Complete Response to Neoadjuvant Chemotherapy in Different Molecular Subtypes of Breast Cancer” in volume 23 on page 47.This article was initially published on the Journal of Breast Cancer with a misspelled the abbreviation in figure 3. The abbreviation ‘HP’ should be corrected as ‘HR’.

PURPOSE: Tau is a microtubule-associated protein that can be found in both normal and abnormal breast cells. Whether the expression of Tau protein can predict the response to neoadjuvant chemotherapy (NACT) is still unclear. In this study, we assessed the role of Tau protein expression in predicting a pathological complete response (pCR) to NACT for different subtypes of breast cancer. METHODS: Four hundred and sixty-eight eligible patients were retrospectively recruited in our study. The relationship between clinicopathologic factors, including Tau protein expression, and pCR in different subtypes was evaluated using logistic regression analysis. Correlation between Tau and disease-free survival (DFS) and overall survival (OS) was performed using Kaplan–Meier analysis. RESULTS: The expression of Tau protein was negatively correlated with pCR, especially in triple-negative breast cancer (TNBC). No significant difference was observed in the luminal human epidermal growth factor receptor-2 (HER2)-negative subtype and HER2-positive subtype. Patients with pCR were associated with better DFS and OS (p < 0.05). However, Tau protein expression had no association with either DFS or OS (p > 0.05). CONCLUSION Tau protein expression can predict pCR before NACT in TNBC, but there was no correlation between Tau expression and DFS or OS.

Auditory neuropathy spectrum disorder (ANSD) represents a variety of sensorineural deafness conditions characterized by abnormal inner hair cells and/or auditory nerve function, but with the preservation of outer hair cell function. ANSD represents up to 15％ of individuals with hearing impairments. Through mutation screening, bioinformatic analysis and expression studies, we have previously identified several apoptosis-inducing factor (AIF) mitochondria-associated 1 (AIFM1) variants in ANSD families and in some other sporadic cases. Here, to elucidate the pathogenic mechanisms underlying each AIFM1 variant, we generated AIF-null cells using the clustered regularly interspersed short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) system and constructed AIF-wild type (WT) and AIF-mutant (mut) (p.T260A, p.R422W, and p.R451Q) stable transfection cell lines. We then analyzed AIF structure, coenzyme-binding affinity, apoptosis, and other aspects. Results revealed that these variants resulted in impaired dimerization, compromising AIF function. The reduction reaction of AIF variants had proceeded slower than that of AIF-WT. The average levels of AIF dimerization in AIF variant cells were only 34.5％?49.7％ of that of AIF-WT cells, resulting in caspase-independent apoptosis. The average percentage of apoptotic cells in the variants was 12.3％?17.9％, which was significantly higher than that (6.9％?7.4％) in controls. However, nicotinamide adenine dinucleotide (NADH) treatment promoted the reduction of apoptosis by rescuing AIF dimerization in AIF variant cells. Our findings show that the impairment of AIF dimerization by AIFM1 variants causes apoptosis contributing to ANSD, and introduce NADH as a potential drug for ANSD treatment. Our results help elucidate the mechanisms of ANSD and may lead to the provision of novel therapies.

Objective:To evaluate the efficacy and safety of endoscopic ultrasound-guided selective varices devascularization (EUS-SVD) for the treatment of esophagogastric varices.Methods:A total of 43 cases of liver cirrhosis with esophageal and gastric varices at the First Affiliated Hospital of Anhui Medical University from February to December 2021 were included in a retrospective cohort study. The cases were divided into two treatment groups based on endoscopic treatment: EUS-SVD group ( n=22) and conventional endoscopic sclerosant injection group (conventional gastroscopy group, n=21). The doses of sclerosants and tissue glue, effective rate of esophageal varice treatment within 2 months after surgery, rebleeding rate within 3 months after surgery, and adverse reactions were compared. Results:The differences in terms of mean patient age, gender composition, etiology of liver cirrhosis, Child-Pugh classification of liver function, classification of esophageal varices, composition of endoscopic treatment indications, and mean maximum diameter of gastric varices were not statistically significant between the two groups ( P>0.05), indicating the comparability of baseline data. Perforating veins outside the gastric wall of gastric varices could be detected during the procedure in the EUS-SVD group, and disappearance of gastric varices after injection treatment could be determined, while these two indicators could not be detected in the conventional gastroscopy group. The amounts of sclerosing agents and tissue adhesives used in the EUS-SVD group were 7.54±3.10 mL and 1.30±0.57 mL, respectively, while the corresponding amounts in the conventional gastroscopy group were 7.57±3.50 mL ( t=0.026, P=0.980) and 1.38±0.67 mL ( t=-0.452, P=0.654), respectively. The effective treatment rate for esophageal varice within 2 months after surgery was 63.6% (14/22) in the EUS-SVD group and 52.4% (11/21) in the conventional gastroscopy group, but the difference was not statistically significant ( χ2=0.559, P=0.455). The rebleeding rate within 3 months after surgery was 4.5% (1/22) in the EUS-SVD group, significantly lower than the rate of 33.3% (7/21) in the conventional gastroscopy group ( P=0.021). Neither group experienced events of ectopic embolism or death. There was no statistically significant difference between the two groups in terms of postoperative pain, fever, nausea and vomiting, or rebleeding rate within 72 hours after surgery ( P>0.05). The incidence of gastric fundus ulcers was 9.1% (2/22) in the EUS-SVD group, significantly lower than the rate of 42.9% (9/21) in the conventional gastroscopy group ( χ2=6.435, P=0.011). Conclusion:EUS-SVD treatment for esophagogastric varices is safe and effective. It can clearly display the deep-seated intramural vessels of the gastric wall, measure the diameter of the blood vessels, accurately inject tissue glue, occlude the varicose veins and perforating vessels, and reduce the occurrence of postoperative ulcers and rebleeding.
