Objective:To evaluate the performance of an artificial intelligence-based endoscopic virtual ruler (EVR) for non-invasive measurement of esophageal varices (EV) diameter.Methods:Patients with liver cirrhosis and EV hospitalized at the First Affiliated Hospital of Anhui Medical University between October 2022 and May 2023 were prospectively enrolled. EV diameter was measured using visual estimation, esophageal varix manometer (EVM), and EVR, with procedure times recorded. The intraclass correlation coefficient (ICC) was used to assess the consistency of EV diameter measurement obtained from the three methods, and repeated-measures ANOVA was used to compare differences in time measurements across three methods.Results:The study included 41 patients with liver cirrhosis and EV. Inter-observer ICC for visual estimation was 0.594, versus 0.840 for EVM and 0.884 for EVR. The ICC value between the EV diameters measured by EVR and EVM was higher than that of the visual assessment. The ICC value between EV diameter measurement by EVM and EVR was 0.991. Measurement times differed significantly across methods ( P<0.001): visual estimation 18.6±2.2 s (14.7-23.3 s), EVR 41.5±4.1 s (31.7-50.3 s), and EVM 170.8±26.4 s (129.3-229.3 s). Repeated measures analysis of variance (corrected using Greenhouse-Geisser) revealed significant differences in time across the three measurement methods [ F(1.033, 41.313)=1 233.800, P<0.001]. Subsequent Bonferroni post-hoc tests revealed significant differences in time between all method pairs ( P<0.001). Conclusion:EVR provides rapid, non-invasive EV diameter measurements with excellent agreement to EVM assessment, offering an efficient alternative to conventional techniques.

ObjectiveTo explore the association between daily executive function and core symptoms， the symptoms of attention deficit hyperactivity disorder （ADHD） in children with autism spectrum disorder （ASD）， and the moderating effect of theory of mind and other cognitive abilities on this association. MethodsChildren aged 6-12 years with ASD were recruited， and 86 children were identified according to the inclusion and exclusion criteria. Wechsler Intelligence Test for Children， Fourth Edition （WISC-Ⅳ）， Strange Story Test （SST） and Behavior Rating Inventory of Executive Function （BRIEF） were used to evaluate children's cognitive ability. Swanson Nolan and Pelham-Version Ⅳ Scale （SNAP-Ⅳ）， Social Responsiveness Scale （SRS）， and Repetitive Behavior Scale-Revise （RBS-R） were used to assess the severity of ADHD symptoms， social impairment， and repetitive stereotyped behavior. Multiple linear regression was used to explore the association between daily executive function and ADHD symptoms， social impairment， repetitive stereotyped behaviors. ResultsAfter controlling for the score of strange stories， verbal comprehension index （VCI） and other factors， the full scale score and each index of BRIEF were positively correlated with full scale score of SNAP （b = 0.619-0.741， b’ = 0.637-0.755）， SRS （b = 0.928-1.200， b’ = 0.417-0.513） and RBS-R （b = 0.326-0.525， b’ = 0.339-0.520） in children with ASD （P< 0.05）， and the SNAP total score was more strongly correlated with the full scale BRIEF score and each index score （b’ = 0.637-0.755，P< 0.01）. In addition to daily executive function， strange stories score （b = -2.218- -1.839） and age （b = 3.181-4.037） were also the important factors affecting the social function of children with ASD （P< 0.01）. There were no moderating effects of strange stories score and age on the association between BRIEF score and full scale score of SNAP， SRS， and RBS-R（P> 0.05）. ConclusionThe deficits of daily executive function in school-aged ASD children are significantly associated with core symptoms and ADHD symptoms， and the association is independent of other cognitive domains， such as theory of mind and verbal comprehension intelligence quotient.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

OBJECTIVE To explore the efficacy of Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction on adult chronic insomnia and its effect on hypnotic withdrawal.METHODS 187 patients with chronic insomnia were included for anal-ysis,including 102 in the traditional Chinese medicine(TCM)group and 85 in the western medicine group.The TCM group was trea-ted with Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction,while the western medicine group was treated with benzodiazepine under the consideration of doctor.The intervention period was 1 month,with assessments using the Pittsburgh Sleep Quality Index(PSQI)conducted before and after the intervention.Follow-up evaluations were performed at 3 months and 6 months re-spectively after the intervention.RESULTS There was no significant difference between the two groups at baseline.After the inter-vention,the PSQI scores of patients in both groups were significantly improved(P<0.01).Among them,the TCM group was better than the western medicine group in the improvement of sleep quality and sleeping pills,total PSQI score reduction(P<0.01).The re-sults of linear regression analysis showed that after controlling for confounding factors,the regression coefficients of the TCM group in two different models were1.821 and 1.922 respectively,and the former was statistically significant(P<0.05).By screening patients who took hypnotics at baseline in the TCM group and comparing them with those in the western medicine group,the influencing factors of hypnotic withdrawal were analyzed.During the 3-month follow-up,25 out of 39 patients in the TCM group and 17 out of 80 patients in the western medicine group had hypnotic withdrawal(χ2= 19.25,P<0.001);during the 6-month follow-up,23 of the 39 patients in the TCM group and 18 of the 79 patients in the western medicine group had hypnotic withdrawal(χ2= 13.53,P<0.001),the with-drawal rate of patients in the TCM group was significantly higher than that in the western medicine group.Further regression analysis showed that after adjusting for confounding factors,the results showed that the western medicine group had a significantly higher rate of not withdrawal than the TCM group at 3 months(OR=5.50,95%CI:2.30～13.72)and 6 months(OR=6.43,95%CI:2.54～17.77),and the results were statistically different(P<0.05).CONCLUSION Sour Jujube Seed Decoction combined with Huangli-an Wendan Decoction is effective in treating adult chronic insomnia and assisting in hypnotic withdrawal.

OBJECTIVE: To compare the clinical efficacy between Wei's triple nine needling combined with esculin and digitalis glycosides eye drops and esculin and digitalis glycosides eye drops alone for presbyopia complicated with visual fatigue of liver depression and spleen deficiency. METHODS: Forty-six cases (92 eyes) with presbyopia complicated with visual fatigue of liver depression and spleen deficiency were randomly divided into an observation group (23 cases) and a control group (23 cases, 2 cases dropped off). The cases in the observation group were treated with Wei's triple nine needling and esculin and digitalis glycosides eye drops. The acupoints included Shangming (Extra), Chengqi (ST 1), Cuanzhu (BL 2) to Jingming (BL 1), Sizhukong (TE 23) to Taiyang (EX-HN 5), etc; the needling was given once every other day, three times a week, and the eye drops were given one drop each time, three times a day. The cases in the control group were only treated with the eye drops. Both groups were treated for 7 days as one course of treatment, and 2 courses of treatment were given. The visual fatigue core symptoms score, adjustment amplitude, adjustment lag and best average corrected visual acuity were observed in the two groups before treatment, 1 week and 2 weeks into treatment, respectively. RESULTS: Compared before treatment, the visual fatigue core symptoms scores in the two groups were decreased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment amplitude was increased after 2-week treatment (P<0.05), while in the control group, the adjustment amplitude was increased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment lag was decreased after 1-week and 2-week treatment (P<0.05). After 2-week treatment, the visual fatigue core symptoms score in the observation group was lower than that in the control group, and the adjustment amplitude was higher than that in the control group (P<0.05). There were no significant differences in adjustment lag and best average corrected visual acuity between the two groups after 1-week and 2-week treatment (P>0.05). CONCLUSION Wei's triple nine needling combined with esculin and digitalis glycosides eye drops could improve the visual fatigue and eye regulation ability in patients with presbyopia complicated with visual fatigue of liver depression and spleen deficiency, and the effect is better than esculin and digitalis glycosides eye drops alone.

This study aimed to observe the intervention effect of Jianpi Huogu Formula(JPHGF) on the functional damage of vascular endothelial cells caused by glucocorticoid, and explore its action mechanism from the PI3 K/Akt and mitogen activated protein kinase(MAPK) signaling pathways. The extracted thoracic aorta ring of normal SD rats were intervened first with vascularendothelial growth factor(VEGF, 20 μg·L-1) and/or sodium succinate(MPS, 0. 04 g·L-1) in vitro and then with JPHGF(8, 16, and 32 μg·L-1) for five mcontinuous ethylpdays, rednisolofollowed nebythe statistics of the number, length, and area of microvessels budding fromvascular rings. In addition, the human umbilical vein endothelial cells(HUVECs) induced by VEGF(20 μg·L-1) were added with MPS(0. 04 g·L-1) and then with JPHGF(8, 16, and 32 μg·L-1) for observing the migration, invasion, and luminal formation abilities of HUVECs in the migration, invasion and luminal formation experiments. The protein expression levels of PI3 K, p-Akt, p-JN K, and p-ERK in HUVECs were assayed by Western blot. The results showed that JPHGF dose-dependently improved the num-ber,length, and area of microvessels in MPS-induced rat thoracic aortic ring, reversed the migration, invasion and lumen formation abiliti es of HUVECs reduced by MPS, and up-regulated the protein expression levels of PI3 K, p-Akt, and p-JNK in HUVECs. All thesehave suggested that JPHGF exerts the protective effect against hormone-induced damage to the angiogenesis of vascular endothelial cells by activating the PI3 K/Akt and MAPK signaling pathways, which has provided reference for exploring the mechanism of JPHGF in treating s teroid-induced avascular necrosis of femoral head(SANFH) and also the experimental evidence for enriching the scientific connotationof spleen-invigorating and blood-activating therapy.

PURPOSE: Plasma cells and immunoglobulins (Igs) play a pivotal role in the induction and maintenance of chronic inflammation in nasal polyps. During secondary immune responses, plasma cell survival and Ig production are regulated by the local environment. The purpose of the present study was to investigate the presence of long-lived plasma cells (LLPCs) and specific survival niches for LLPCs in human nasal polyps.METHODS: Nasal mucosal samples were cultured with an air-liquid interface system and the Ig levels in culture supernatants were analyzed by enzyme-linked immunosorbent assay. The characteristics of LLPCs in nasal polyps were determined by immunohistochemistry and immunofluorescence. The expression of neurotrophins as well as their receptors was detected by quantitative real-time polymerase chain reaction, immunohistochemistry, immunofluorescence, and Western blotting.RESULTS: The numbers of CD138⁺ total plasma cells and BCL2⁺ plasma cells were increased in both eosinophilic and non-eosinophilic nasal polyps compared with those in normal tissues. The production of IgG, IgA, and IgE was detected in culture supernatants even after a 32-day culture of nasal polyps. Although the total numbers of plasma cells were decreased in nasal polyps after culture, the numbers of BCL2⁺ plasma cells remained stable. The expression of nerve growth factor (NGF) as well as tropomyosin receptor kinase (Trk) A, a high-affinity receptor for NGF, was upregulated in both eosinophilic and non-eosinophilic nasal polyps. In addition, BCL2⁺ plasma cell numbers were positively correlated with NGF and TrkA mRNA expression in nasal mucosal tissues. Polyp plasma cells had the expression of TrkA.CONCLUSIONS: Human nasal polyps harbor a population of LLPCs and NGF may be involved in their prolonged survival. LLPCs may be a novel therapeutic target for suppressing the local Ig production in nasal polyps.

Objective To investigate the inhibitory effect of metformin on high glucose-induced lipolysis and further elucidate the underlying mechanisms,for better understanding of metformin.Methods Adipocytes were isolated from epididymal fat pads of Sprague-Dawley rats.After isolation and digestion,packed adipocytes were divided into four groups according to the glucose and metformin in the media,control A group containing 5 mmol · L-1 glucose,control B group containing 25 mmol · L-1 glucose,test A group containing 500 μmol · L-1 metformin with 5 mmol · L-1 glucose and test B group containing 25 mmol · L-1 glucose with 500 μmol · L-1 metformin or at the concentrations as planned.After incubation,glycerol accumulated or released into the media in 30 minutes was determined by the use of a colorimetric assay and served as an index of lipolysis.The expressions of phosphorylated and total perilipin as well as adipose triglyceride lipase (ATGL) were examined by Western Blot.Adipose lipases activity was assayed by using an enzymatic method.Results The glycerol release in the control B and test B groups were (1.61 ± 0.08) and (0.50 ± 0.06) μmol · mL-1 packed cell volume,respectively,suggesting that metformin significantly inhibited the lipolytic action of high glucose (P ＜0.001).Such an inhibitory effect lasted from 16 h to 24 h after incubation.The adipose lipases activity in the control B and test B groups were (344.28 ± 65.98) and (200.44 ± 64.25)μmol glycerol · mg protein-1 · h-1,respectively,and thus metformin caused a 41.78％ (P ＜0.05) reduction of adipose lipases activity elevated by high glucose.Compared with control B group,metformin in test B group significantly attenuated the phosphorylation of perilipin induced by high glucose (P ＜ 0.01).However,the protein amount of total ATGL was not changed in control B group by high glucose or in test group (A and B) by metformin compared with that of control A group (all P ＞ 0.05).Conclusion Metformin inhibits high glucose-induced lipolysis through eliminating perilipin phosphorylation and suppressing lipolytic lipases activity.We suggest that such antilipolytic effect of metformin in hyperglycemia could be a molecular basis by which metformin reduces the release of free fatty acids from adipose tissue to bloodstream and thus ameliorates insulin resistance in diabetes.
