BACKGROUND Intervention to improve outcomes in cirrhotic patients (CP) after hospital discharge often focus on 30 d readmission rate (RR). However, recent studies suggest dissociation between RR and survival. At our center, CP are now offered outpatient telephonic transitional care (OTTC) by a care coordinator for 30 d after hospital discharge. AIM To determine the effect of OTTC on survival in CP. METHODS In this cohort study from a tertiary center, CP who received OTTC formed the intervention group. They were compared with a control group discharged during the same period. Mortality and RR were compared between the groups. RESULTS After OTTC introduction, 194 CP were discharged. After applying exclusion criteria, 169 CP (51% male, mean age 58 years ± 12 years) were included. OTTC group comprised 76 patients and was compared with 93 controls. Baseline disease and index admission related characteristics were not significantly different between the groups. The intervention group showed significantly higher 6 mo survival compared to controls (84.2% vs 68.8%;P = 0.03), while RR at 1, 3, and 6 mo were comparable. On multivariable analysis, the intervention group showed lower odds for mortality compared to the controls (hazard ratio: 0.4;95% confidence interval: 0.2-0.82;P = 0.012), while higher model for endstage liver disease scores were associated with higher mortality (hazard ratio: 1.05;95% confidence interval: 1.01-1.1;P = 0.024).CONCLUSION CP provided OTTC had higher 6 mo survival compared to controls without a difference in RR. Use of RR to gauge quality of care provided during hospitalization or subsequent transitional care programs should be revisited.

AIM: To assess the safety and efficacy of self-expandable metal stents(SEMSs) for malignant colorectal obstruction. METHODS: Data regarding technical success, clinical success, and procedure related complications were collected from included studies. Der Simonian-Laird random effects model was used to generate the overall outcome. Thirty international studies with a total of 2058 patients with malignant colorectal obstruction were included. RESULTS: The technical and clinical success rates for SEMS placement were 94%(95%CI: 92-96) and 91%(95%CI: 88-93), respectively. Overall complication rate for SEMS was 23%(95%CI: 18-29). Stent migration8%(95%CI: 6-10) and stent obstruction 8%(95%CI: 6-11) were the most common complications, followed by perforation 5%(95%CI: 4%-7%). Surgical or endoscopic re-interventions were needed in 14%(95%CI: 10-18) of patients. Endoscopic repeat stent placement was required in 8%(95%CI: 6-10), while surgical intervention was needed in 6%(95%CI: 4-8).CONCLUSION: SEMS are effective when used as palliation or bridge to surgery for malignant colorectal obstruction with high technical and clinical success. About 14% of patients require repeat endoscopic or surgical intervention for stent failure or to manage stent related complications.

AIM： To determine the diagnostic yield of the “third eye retroscope”, on adenoma detection rate during screening ***： The “third eye retroscope” when used with standard colonoscopy provides an additional retro-grade view to visualize lesions on the proximal aspects of folds and fexures. We searched MEDLINE （PubMed and Ovid）, SCOPUS （including MEDLINE and EMBASE databases）, Cochrane Database of Systemic Reviews, Google Scholar, and CINAHL Plus databases to identify studies that evaluated diagnostic yield of “third eye retroscope” during screening colonoscopy. DerSimonian Laird random effects model was used to generate the overall effect for each outcome. We evaluated statistical heterogeneity among the studies by using the Cochran Q statistic and quantifed by I2 ***： Four distinct studies with a total of 920 pa-tients, mean age 59.83 （95%CI： 56.77-62.83） years, were included in the review. The additional adenoma detection rate （AADR） defined as the number of ad-ditional adenomas identified due to “third eye retro-scope” device in comparison to standard colonoscopy alone was 19.9% （95%CI： 7.3-43.9）. AADR for right and left colon were 13.9% （95%CI： 9.4-20） and 10.7 （95%CI： 1.9-42）, respectively. AADR for polyps ≥ 6 mm and ≥ 10 mm were 24.6% （95%CI： 16.6-34.9） and 24.2% （95%CI： 12.9-40.8）, respectively. The ad-ditional polyp detection rate defined as the number of additional polyps identifed due to “third eye retro-scope” device in comparison to standard colonoscopyalone was 19.8% （95%CI： 7.9-41.8）. There were no complications reported with use of “third eye retro-scope” ***： The “third eye retroscope” device when used with standard colonoscopy is safe and de-tects 19.9% additional adenomas, compared to stan-dard colonoscopy alone.

Neural Regeneration Research 2025年第3期20卷 779-793页

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

Region-dependent micro damage of enamel under indentation

Acta Mechanica Sinica 2012年第6期28卷 1651-1658页

作者： Bing-Bing An rao-rao Wang .Dong-Sheng Zhang rao-rao Wang Dong-Sheng Zhang Shanghai Institute of Applied Mathematics and Mechanics 200072 Shanghai China The Tenth People's Hospital of Tongji University 200072 Shanghai China Department of Mechanics Shanghai University200444 Shanghai China Shanghai Key Laboratory of Mechanics in Energy Engineering 200072 Shanghai China

The objective of this investigation is to explore the region-dependent damage behavior of enamel, as well as to develop a good understanding of the deformation mech- anisms of enamel with numerical modeling. Nanoinden- tation experiments have been performed to investigate the load-penetration depth responses for outer and inner enamel. Results show that the unloading curve does not follow the loading curve, and degradation of stiffness in the unloading curve is observed. Based on the experimental data, a physi- cal quantity, the chain density in protein, has been introduced to the Drucker-Prager plastic model. Numerical simulations show that the simulated load-penetration depth curves agree with the experiments, and the stiffness degradation behav- iors of outer and inner enamel are captured by the numerical model. The region-dependent damage behavior of enamel could be revealed by the numerical model. The micro dam- age affected area at inner enamel is larger than that at outer enamel, indicating that the inner enamel experiences more micro damage than the outer one. Compared with its outer counterpart, the inner enamel which is rich in organic protein could break more internal protein chains to dissipate energy and to enhance its resistance to fracture accordingly.

鉴于当前政策、理论和实践领域对农村集体经济本质缺乏共识,本研究采用胡塞尔现象学的方法论,特别是一般现象学还原、本质还原和先验还原等技术,系统地审视了“农村集体经济应该是什么”这一核心议题。通过全面梳理当前对农村集体经济的多维认知,从而为其本质探索提供更为宽广的视角。在搁置既有认识的基础上,采用更加开放的态度识别出土地集体所有制是农村集体经济的共相,这一发现为理解其本质提供了关键线索。进一步从源初意向性与结构性剖析农村集体经济,揭示其本质在于注重公正,并凸显了其深厚的社会性和伦理性。这种本体论式反思既验证了马克思主义理论关于集体所有制经济的科学性及其生命力,更展示了中国农村集体经济独有的文化烙印。同时,跨学科的研究方法或为理解农村集体经济提供了新的视角,为推动其持续健康发展提供有益的思考。

Particuology 2010年第6期8卷 549-555页

作者： Yuanqiao rao Corporate R&D The Dow Chemical Company Freeport 7X 77541 USA

There is no doubt about the potential technological significance of nanofluids. The promising application areas have been identified as effective heat transfer fluids, contrast agents in magnetic resonance imaging, magnetohyperthermia treatment, precursors to high performance nanocomposites and ordered nanostructures. However, commercial applications are rare, in part due to the limited understanding of the nanofluid fundamentals such as colloid stability, phase diagrams and rheology. This paper intends to provide a brief overview of the scientific disciplines that are important to nanofluids, and the interconnection among different disciplines in order to gain a perspective on the future development of this intriguing area.
