The 90% effective dose (ED90) of remimazolam for inhibiting responses to the insertion of a duodenoscope during ERCP.

BACKGROUND: Compared to midazolam, remimazolam has a faster onset and offset of hypnotic effect, as well as cardiorespiratory stability, this study aims to determine the 90% effective dose (ED90) of remimazolam to inhibit responses to insertion of a duodenoscope during endoscopic retrograde cholangiopancreatography (ERCP). METHODS: A dose-response study was carried out undergoing ERCP who received remimazolam-alfentanil anesthesia using 10 µg/kg of alfentanil between September 2021 and November 2021. The initial dose of remimazolam was 0.2 mg/kg. The dose was then decided based on the responses of earlier patients by exploiting the sequential ascend and descend according to a 9: 1 biased coin design. Upon failure, the dose of remimazolam was increased by 0.025 mg/kg in the next patient. When the insertion was successful, the succeeding patient was randomized to an identical dose or a dose that was lower by 0.025 mg/kg.The ED90 of remimazolam for inhibiting responses to the insertion of a duodenoscope during ERCP was calculated. Adverse events and complications of remimazolam were recorded. RESULTS: A total of 55 elderly patients (age > 65) were included in the study. 45 successfully anesthetized patients, and 10 unsuccessfully. The ED90 of remimazolam was 0.300 mg/kg (95% CI = 0.287-0.320). ED95 was 0.315 (95% CI = 0.312-0.323) and ED99 was 0.323 (95% CI = 0.323-0.325). Among the patients, 9 patients developed hypotension, 2 patients developed bradycardia and 1 patient developed tachycardia, and hypoxia occurred in 2 patients. CONCLUSIONS: A loading dose of 0.300 mg / kg of remimazolam for elderly patients undergoing ERCP can safely, effectively, and quickly induce patients to fall asleep and inhibit responses to the insertion of a duodenoscope. TRIAL REGISTRATION: The study protocol was registered at the website ClinicalTrials.gov on 22/09/2021(NCT05053763).

OBJECTIVES: To investigate the association between auditory processing and problem behaviors in preschool children, as well as the mediating role of executive function. METHODS: A total of 2 342 preschool children were selected from 7 kindergartens in Nanjing, China from June to August 2021. They were evaluated using Preschool Auditory Processing Assessment Scale, Conners Parent Symptom Questionnaire, and Behavior Rating Inventory of Executive Functioning-Preschool version. Children with different demographic features were compared in the scores and the abnormality rates of auditory processing, problem behaviors, and executive function. The influencing factors of the total scores of auditory processing, problem behaviors, and executive function were evaluated using multiple linear regression analysis. Whether executive function was a mediating factor between auditory processing and executive function was examined. RESULTS: Sex and grade were the main influencing factors for the total score of auditory processing (P<0.05), and sex, grade, parental education level, and family economic status were the main influencing factors for the total scores of problem behaviors and executive function (P<0.05). The auditory processing score (rs=0.458, P<0.05) and problem behavior score (rs=0.185, P<0.05) were significantly positively correlated with the executive function score, and the auditory processing score was significantly positively correlated with the problem behavior score (rs=0.423, P<0.05). Executive function played a partial mediating role between auditory processing and problem behaviors, and the mediating effect accounted for 33.44% of the total effect. CONCLUSIONS: Auditory processing can directly affect the problem behaviors of preschool children and indirectly affect problem behaviors through executive function.

OBJECTIVES: To investigate the characteristics of auditory processing (AP) in preschool children with attention deficit hyperactivity disorder (ADHD) using Preschool Auditory Processing Assessment Scale (hereafter referred to as "auditory processing scale"). METHODS: A total of 41 children with ADHD and 41 typically developing (TD) children were assessed using the auditory processing scale, SNAP-IV rating scale, and Conners' Kiddie Continuous Performance Test (K-CPT). The auditory processing scale score was compared between the TD and ADHD groups. The correlations of the score with SNAP-IV and K-CPT scores were assessed. RESULTS: Compared with the TD group, the ADHD group had significantly higher total score of the auditory processing scale and scores of all dimensions except visual attention (P<0.05). In the children with ADHD, the attention deficit dimension score of the SNAP-IV rating scale was positively correlated with the total score of the auditory processing scale (rs30=0.531, P<0.05; rs27=0.627, P<0.05) as well as the scores of its subdimensions, including auditory decoding (rs=0.628, P<0.05), auditory attention (rs=0.492, P<0.05), and communication (rs=0.399, P<0.05). The hyperactivity-impulsivity dimension score of the SNAP-IV rating scale was positively correlated with the hyperactivity-impulsivity dimension score of the auditory processing scale (rs=0.429, P<0.05). In the children with ADHD, the attention deficit dimension score of the K-CPT was positively correlated with the total score (rs30=0.574, P<0.05; rs27=0.485, P<0.05) and the hyperactivity-impulsivity dimension score (rs=0.602, P<0.05) of the auditory processing scale. CONCLUSIONS: Preschool children with ADHD have the risk of AP abnormalities, and the auditory processing scale should be used early for the screening and evaluation of AP abnormalities in children.

[Effect of mild moxibustion at 45 ℃ with different durations at "Zusanli" （ST36） on the inflammatory factors in the abdominal aorta of hyperlipidemia rats].

OBJECTIVE: To investigate the effects of mild moxibustion at 45°C on the chronic inflammatory response of the abdominal aorta in rats with hyperlipidemia and the effects of different moxibustion durations. METHODS: Thirty-six SD rats were randomly divided into the following groups： blank control group (2 weeks), model group (2 weeks), moxibustion group (2 weeks), blank group (4 weeks), model group (4 weeks), and moxibustion group (4 weeks). A model of hyperlipidemia with chronic inflammation was established through high-fat diet feeding for 8 weeks. Rats in the moxibustion groups received mild moxibustion treatment at bilateral "Zusanli"(ST36) at 45 °C, 10 min every time, once a day, for consecutive 2 or 4 weeks. The morphology of the abdominal aorta in each group was observed by using HE staining. Contents of serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), oxidized low-density lipoprotein (ox-LDL), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), endothelin-1 (ET-1) and the contents of nitric oxide (NO), ox-LDL, and ET-1 in the abdominal aorta were measured by using ELISA. Protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta of rats in each group were detected by using Western blot and real-time fluorescence quantitative PCR respectively. The positive expression of IL-6 in the abdominal aorta of rats was detected by Immunofluorescence. RESULTS: Compared to the blank control group, rats in the model group had increased contents of LDL, TC, TG, ox-LDL, VCAM-1, ICAM-1, IL-6, TNF-α, and ET-1 in the serum, increased contents of ox-LDL and ET-1 in the abdominal aorta, increased protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta(P<0.01, P<0.05, P<0.001), with decreased HDL content in the serum, decreased NO content in the abdominal aorta (P<0.01, P<0.05), as well as dark pink abdominal aorta, rough textures in the adventitia, media, and intima, and rough endothelial layer. Compared to the model group(2 weeks), LDL, ICAM-1, ET-1 contents in the serum, ox-LDL content in the abdominal aorta were decreased(P<0.05), while serum IL-6 and TNF-α contents, and NO content in the abdominal aorta were significantly increased(P<0.01, P<0.05), with smoother vascular walls, and relatively clear nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(2 weeks). Compared to the model group(4 weeks), contents of LDL, TC, TG, VCAM-1, ICAM-1, IL-6, TNF-α, ox-LDL, and ET-1 in the serum, ox-LDL and ET-1 contents in abdominal aorta, protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta were significantly decreased(P<0.05, P<0.01), while HDL content in the serum and NO content in the abdominal aorta were significantly increased(P<0.05, P<0.01), with smoother vascular walls, and relatively clear nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(4 weeks). In addition, content of HDL in the serum were significantly increased(P<0.05), while TNF-α content in the serum, protein expression of IL-6 in the abdominal aorta were significantly decreased (P<0.001, P<0.05), with smoother vascular walls, and clearer nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(4 weeks), in comparison with the moxibustion group(2 weeks). CONCLUSION: Mild moxibustion of 45 °C at ST36 can improve vascular endothelial damage and inflammatory response induced by high-fat diet by regulating serum lipids, vascular tone, adhesion molecules, and inflammatory factors, of which the effect of moxibustion intervention for 4 weeks is more significant.

[Moxibustion of 45 ℃ at "Zusanli" (ST36) improves vascular endothelial oxidative stress in hyperlipidemia rats].

OBJECTIVE: To explore the antioxidant effect of moxibustion on vascular endothelial function and the under-lying mechanism. METHODS: Forty male SD rats were randomly divided into blank, model, moxibustion and endothelial nitric oxide synthase (eNOS) inhibitor groups, with 10 rats in each group. Hyperlipidemia rat model was established by high fat diet for 8 weeks. Rats in the moxibustion group received 45 ℃ moxibustion at "Zusanli" (ST36) for 10 min once daily for consecutive 4 weeks. Rats in the eNOS inhibitor group received intraperitoneal injection of eNOS inhibitor L-NAME (1 mg/100 g) at the same time of moxibustion intervention.

A randomized, controlled clinical trial comparing remimazolam to propofol when combined with alfentanil for sedation during ERCP procedures.

STUDY OBJECTIVE: In many countries, the combination of propofol and opioid is used as the preferred sedative regime during ERCP. However, the most serious risks of propofol sedation are oxygen deficiency and hypotension. Compared to midazolam, remimazolam has a faster onset and offset of hypnotic effect, as well as cardiorespiratory stability, and to achieve widespread acceptance for procedural sedation, remimazolam must replace propofol which is the most commonly used for procedural sedation. The objective of this study was to compare the safety and efficacy profiles of the remimazolam and propofol when combined with alfentanil for sedation during ERCP procedures. DESIGN: A randomized, controlled, single-center trial. SETTING: The Endoscopic Centre of Tianjin Nankai Hospital, China. PATIENTS: 518 patients undergoing elective ERCP under deep sedation. INTERVENTIONS: Patients scheduled for ERCP were randomly assigned to be sedated with either a combination of remimazolam-alfentanil or propofol-alfentanil. MEASUREMENTS: The primary outcome was the prevalence of hypoxia, which was defined as SpO2 < 90% for >10 s. Other outcomes were the need for airway maneuver, procedure, and sedation-related outcomes and side effects (e.g., nausea, vomiting, and cardiovascular adverse events). MAIN RESULTS: A total of 518 patients underwent randomization. Of these, 250 were assigned to the remimazolam group and 255 to the propofol group. During ERCP, 9.6% of patients in the remimazolam group showed hypoxia, while in the propofol group, 15.7% showed hypoxia (p = 0.04). The need for airway maneuvering due to hypoxia was significantly greater in the propofol group (p = 0.04). Furthermore, patients sedated with remimazolam had a lower percentage of hypotension than patients sedated with propofol (p < 0.001). Patients receiving remimazolam sedation expressed higher satisfaction scores and were recommended the same sedation for the next ERCP. The procedure time in the remimazolam group was much longer than in the propofol group due to the complexity of the patient's disease, which resulted in a longer sedation time. CONCLUSION: During elective ERCP, patients administered with remimazolam showed fewer respiratory depression events under deep sedation with hemodynamic advantages over propofol when administered in combination with alfentanil.

Notes on the Genus Aceratoneuromyia Girault (Hymenoptera: Eulophidae).

Fruit flies in the family Tephritidae are well known as economically important pests of edible fruits and can often cause serious damage and losses to both agriculture and the economy. One of the common parasitoids of fruit flies, Aceratoneuromyia indica (Silvestri), has been used in biological programs. However, the biocontrol utilities of parasitoids are impeded by the difficulties of proper identification. Species of the genus Aceratoneuromyia Girault (Hymenoptera: Eulophidae), usually developed as parasitoids of fruit flies, are studied here. Trjapitzinichus Kostjukov and Kosheleva is proposed as a new synonym under Aceratoneuromyia. Three new species of Aceratoneuromyia, A. bilinis Huangfu and Cao sp. nov., A. carinata Cao and Zhu sp. nov., and A. trilinus Cao and Zhu sp. nov., are described and illustrated from China. Aceratoneuromyia indica is also treated here with diagnosis and illustrations. DNA barcodes of A. bilinis and A. indica and a key to the world species of Aceratoneuromyia are provided. This study provided important identification information of parasitoids with morphology and molecular evidence, which is useful for imperative needs regarding the identity of parasitoids attacking fruit flies.

Development and validation of a nomogram for early assessment the severity of acute pancreatitis.

BACKGROUND: Acute pancreatitis is an acute inflammatory disorder of the pancreas, and severe acute pancreatitis is associated with high mortality. Early assessment the severity of AP has an important significance for improving clinical outcomes. Our object aimed to develop a nomogram with high simplicity and rapidity for predicting the severity of acute pancreatitis. METHODS: Patients admitted to the Hunan Provincial People's Hospital within 72 h from onset of AP from January 2010 and December 2020 were enrolled to establish a nomogram. Independent predictors were determined using univariate and multivariate analysis and then assembled to construct a predicting nomogram. The performance of proposed nomogram was evaluated by Brier score and Harrell's concordance index (C-index). Meanwhile, clinical data of AP patients from January 2021 to January 2022 were collected for external validation. RESULTS: Album (OR 0.891, 95%CI 0.867-0.917), calcium (OR 0.151, 95%CI 0.084-0.273), neutrophil to lymphocyte ratio (OR 1.055, 95%CI 1.023-1.088) and systemic inflammatory response syndrome (OR 6.292, 95%CI 4.459-8.879) were identified as independent factors of SAP after univariate and multivariate analysis (p < .05). A predictive nomogram was accordingly established using these four independent variables. The internally verified C-index was 0.796 (95% CI 0.773-0.818), Brier score was 0.138. The externally verified C index was 0.820 (95% CI 0.754-0.887). CONCLUSION: A nomogram for predicting the severity of AP was well developed, it may be of great significance for clinicians to quickly assess the progress of AP and choose more-targeted strategies.

Establishment and verification a nomogram for predicting portal vein thrombosis presence among admitted cirrhotic patients.

Background: Portal vein thrombosis (PVT) is an increasingly recognized complication of cirrhosis and possibly associated with mortality. This study aims to evaluate provoking factors for PVT, then establish a concise and efficient nomogram for predicting PVT presence among admitted cirrhotic patients. Materials and methods: All cirrhotic patients admitted in Hunan Provincial People's Hospital between January 2010 and September 2020 were retrospectively reviewed, the clinical and laboratory data were collected. Multivariate logistic regression analysis and the least absolute shrinkage and selection operator regression method were used for screening the independent predictors and constructing the nomogram. The calibration curve was plotted to evaluate the consistent degree between observed outcomes and predicted probabilities. The area under the receiver operating characteristics curve was used to assess the discriminant performance. The decision curve analysis (DCA) was carried out to evaluate the benefits of nomogram. Results: A total of 4,479 patients with cirrhosis were enrolled and 281 patients were identified with PVT. Smoking history, splenomegaly, esophagogastric varices, surgical history, red blood cell transfusion, and D-dimer were independent risk factors for PVT in cirrhosis. A nomogram was established with a good discrimination capacity and predictive efficiency with an the area under the curve (AUC) of 0.704 (95% CI: 0.664-0.745) in the training set and 0.685 (95% CI: 0.615-0.754) in the validation set. DCA suggested the net benefit of nomogram had a superior risk threshold probability. Conclusion: A concise and efficient nomogram was established with good performance, which may aid clinical decision making and guide best treatment measures.

[Research advances in prevention and treatment of intervertebral disc degeneration by targeting mitochondrial quality control].

Intervertebral disc degeneration(IDD) is a common clinical degenerative disease of the musculoskeletal system, which increases the risk of lower back pain, severely reduces patients' quality of life and work efficiency, and imposes a large economic burden on society. Mitochondria, as the "power stations" of eukaryotic cells, are involved in many key biological processes, and their abnormal function can induce cellular dysfunction and lead to the development of a series of degenerative diseases. Recent studies have revealed that mitochondrial quality control(MQC) imbalance, characterized by abnormalities in mitochondrial oxidative stress, kinetics, mitophagy and biogenesis, plays an important role in IDD. The research reviewed the progress of the role of MQC in IDD and summarized traditional Chinese medicine monomers and small molecule compounds targeting MQC for the treatment of IDD, with the aim of providing reference and new ideas for studying novel therapeutic strategies for IDD.

Preoperative ocular biometric parameters were collected, including spherical equivalent(SE), intraocular pressure, axial length, anterior chamber depth(ACD), lens thickness(LT), central corneal thickness, anterior chamber angle(ACA), anterior chamber volume(ACV), white to white corneal diameter(WTW), mean keratometry K1 and K2, and intraoperative implantation size of ICL. The vault was measured by anterior segment optical coherence tomography(AS-OCT)at 1, 3d, 1wk and 1mo after surgery. The patients were divided into insufficient vault group(&#x003C;250μm, 12 eyes), normal vault group(250-750μm, 62 eyes)and excessive vault group(&#x003E;750μm, 24 eyes)according to the vault at 1mo after surgery. The factors affecting the postoperative vault were analyzed.RESULTS:The mean vault values at 1 and 3d, 1wk and 1mo after surgery were 591.05±293.44, 599.62±309.78, 592.22±301.49 and 586.69±285.63μm, respectively. There were significant differences in WTW, ACA, ACV, ACD, ICL size and LT at 1mo after surgery(all P&#x003C;0.05). The regression equation of vault at 1mo after surgery was as follows: vault(μm)=-3142.19+388.25×WTW+10.40×ACA-301.63×LT(R=0.674, R2=0.454, adjusted R2=0.436). WTW had the greatest influence on vault at 1mo after surgery(β=0.47, P&#x003C;0.001), followed by LT(β=-0.34, P&#x003C;0.001)and ACA(β=0.17, P=0.047).CONCLUSION:WTW, ACA and LT were the main factors that affected and predicted the vault at 1mo after ICL/TICL V4c implantation.
