Starting from a reading of Jonathan Edwards' famous sermon "Sinners in the Hands of an Angry God", this paper first analyzes the powerful image of "sinner" in the sermon, then goes on to give a definition of a Christian conception of sin. It is found that while sin is a central conception in the religious system of Christianity, Emptiness is a central idea in Buddhist's doctrine. Understanding this conception is a key step on one's road to the enlightenment. Buddha's emphasis on emptiness is to warn people not to hold everything tight in this world, to stop their craving and grasping, finally to end people's suffering in life. Human beings get salvation through the redemption of their sin in a Christian doctrine, while in a Buddhist doctrine, people can only get enlightened and salvation when they are aware of the empty nature of this world, the universe, and themselves 展开更多

Self-assembly is deemed to be an effective and inspiring strategy to construct programmable and innovative super-ordered structures.Here,we have,for the first time,achieved the large-area super-ordered two-dimensional(2D)emptiness arrays in graphene by silicon dioxide self-assembly pre-occupancy.The prominent uniform periodicity of 2D emptiness arrays in graphene can be flexibly adjusted.The synergistic interaction between the pre-occupancy structural unit and graphene contributes to the successful acquisition of 2D emptiness arrays.The realization of 2D emptiness arrays by self-assembly pre-occupancy strategy would shed light on the rational redaction,fabrication and research of complex 2D super-ordered structure systems and facilitate their applications for various fields,such as highly integrated functional devices,precise location acquisition systems,sensing,separation,and so on. 展开更多

In this article, I will examine the concept of xujing 虚静 (emptiness and stillness) in Daoism and its relationship with the aesthetic appreciation of nature and environmental ethics. Firstly, I will examine the Chinese philosophical understanding of nature through the concept of qi. I point out that qi is characterized by four interrelated features, which are emptiness, creativity, vitality, and stillness. Xujing are also aesthetically appreciated as the objective features of qi. Secondly, ! will discuss why, as the objective features of qi, xujing are considered to be features that have aesthetic value. I argue that empathy is the reason why emptiness as the objective feature of qi is regarded as having aesthetic value. Thirdly, I will discuss how the aesthetic concept of emptiness helps contribute to the construction of place-based environmental ethics. 展开更多

Background: Delayed gastric emptying(DGE) is one of the most common complications after pancreaticoduodenectomy(PD). DGE represents impaired gastric motility without significant mechanical obstruction and is associated with an increased length of hospital stay, increased healthcare costs, and a high readmission rate. We reviewed published studies on various technical modifications to reduce the incidence of DGE. Data sources: Studies were identified by searching Pub Med for relevant articles published up to December 2022. The following search terms were used: “pancreaticoduodenectomy”, “pancreaticojejunostomy”, “pancreaticogastrostomy”, “gastric emptying”, “gastroparesis” and “postoperative complications”. The search was limited to English publications. Additional articles were identified by a manual search of references from key articles. Results: In recent years, various surgical procedures and techniques have been explored to reduce the incidence of DGE. Pyloric resection, Billroth II reconstruction, Braun's enteroenterostomy, and antecolic reconstruction may be associated with a decreased incidence of DGE, but more high-powered studies are needed in the future. Neither laparoscopic nor robotic surgery has demonstrated superiority in preventing DGE, and the use of staplers is controversial regarding whether they can reduce the incidence of DGE. Conclusions: Despite many innovations in surgical techniques, there is no surgical procedure that is superior to others to reduce DGE. Further larger prospective randomized studies are needed. 展开更多

Background:Jianqu has been used to alleviate symptoms in patients with functional dyspepsia,but its specific anti-functional dyspepsia effect is still unclear.Therefore,our study aimed to investigate the impact of Jianqu on functional dyspepsia in mice.Methods:The phytochemical profile of Jianqu was analyzed by UPLC-Q-TOF-MS.Subsequently,Kunming mice were fed a high-calorie or high-protein diet(HCHP)for 7 days,and then orally treated with vehicle or Jianqu(1.62 g/kg body weight(b.w.)and 3.25 g/kg b.w.)for 10 days.A carbon powder solution was used to detect the gastric emptying and intestinal transit rate.The pathological changes in stomach and duodenum were evaluated by hematoxylin-eosin staining.The occludin,claudin-1,ZO-1 and CD45 expression was measured by immunocytochemical staining.Importantly,the serum gastrointestinal hormones were detected by ELISA.In addition,the gut microbiota composition was determined using 16S rRNA gene sequencing.The cecal short chain fatty acids were assessed by gas chromatography.Results:In general,17 phytochemical compounds were identified from Jianqu,which significantly improved the gastric emptying rate and intestinal transit rate(p<0.01),increased the body weight and food intake(p<0.0001)in HCHP mice as well.Though HCHP did not cause significant pathological lesions in the gastrointestinal tract,increased the expression of CD45 in the duodenum(p<0.05)was observed.Notably,Jianqu attenuated this abnormal expression of CD45(p<0.05).The levels of serum gastrointestinal hormones were significantly normalized by Jianqu intervention(p<0.05).Moreover,Jianqu increased the relative abundance of Roseburia as well as short chain fatty acids levels in cecum(p<0.05).Conclusion:The present results showed that Jianqu alleviated dyspeptic symptoms in HCHP mice possibly through reducing the duodenal leukocyte infiltration,and regulating the expression of gastrointestinal hormones.These effects may be partly related to the increasing cecal short chain fatty acids levels probably via gut microbial modulation. 展开更多

Gestational diabetes mellitus(GDM)represents one of the most common medical complications of pregnancy and is important to the well-being of both mothers and offspring in the short and long term.Lifestyle intervention remains the mainstay for the management of GDM.The efficacy of nutritional approaches(e.g.calorie restriction and small frequent meals)to improving the maternal-neonatal outcomes of GDM was attested to by Chinese population data,discussed in two articles in recent issues of this journal.However,a specific focus on the relevance of postprandial glycaemic control was lacking.Postprandial rather than fasting hyperglycaemia often represents the predominant manifestation of disordered glucose homeostasis in Chinese women with GDM.There is now increasing appreciation that the rate of gastric emptying,which controls the delivery of nutrients for digestion and absorption in the small intestine,is a key determinant of postprandial glycaemia in both health,type 1 and 2 diabetes.It remains to be established whether gastric emptying is abnormally rapid in GDM,particularly among Chinese women,thus contributing to a predisposition to postprandial hyperglycaemia,and if so,how this influences the therapeutic response to nutritional interventions.It is essential that we understand the role of gastric emptying in the regulation of postprandial glycaemia during pregnancy and the potential for its modulation by nutritional strategies in order to improve postprandial glycaemic control in GDM. 展开更多

This editorial is stimulated by the article by Alqifari et al published in the World Journal of Diabetes(2024).Alqifari et al focus on practical advice for the clinical use of glucagon-like-peptide-1(GLP-1)receptor agonists(GLP-1RAs)in the management of type 2 diabetes and this editorial provides complementary information.We initially give a brief historical perspective of the development of GLP-1RAs stimulated by recognition of the‘incretin effect’,the substantially greater insulin increase to enteral when compared to euglycaemic intravenous glucose,and the identification of the incretin hormones,GIP and GLP-1.In addition to stimulating insulin,GLP-1 reduces postprandial glucose levels by slowing gastric emptying.GLP-1RAs were developed because native GLP-1 has a very short plasma half-life.The majority of current GLP-1RAs are administered by subcutaneous injection once a week.They are potent in glucose lowering without leading to hypoglycaemia,stimulate weight loss in obese individuals and lead to cardiovascular and renal protection.The landscape in relation to GLP-1RAs is broadening rapidly,with different formulations and their combination with other peptides to facilitate both glucose lowering and weight loss.There is a need for more information relating to the effects of GLP-1RAs to induce gastrointestinal symptoms and slow gastric emptying which is likely to allow their use to become more effective and personalised. 展开更多

[Objectives]To explore the effects of Polygona fallax Hemsl water extract on gastrointestinal motility in normal mice and gastric motility disorder model mice and approximate mechanism.[Methods]Using normal mice and mice with gastric motility disorders(modeled with atropine),the effects of different mass concentration groups of P.fallax Hemsl water extract(0.125,0.250,0.500 g/mL)and domperidone groups on gastric residual rate,small intestine propulsion rate,serum motilin(MLT),vasoactive intestinal peptide(VIP),and tissue morphology were studied.[Results]There was a highly significant difference(P<0.01)in the small intestine propulsion rate of liquid in normal mice among the different concentration groups of P.fallax Hemsl water extract compared to the blank group.The small intestine propulsion rate and gastric residue rate of semi-solid paste were statistically significant compared to the blank group(P<0.05).Among them,there was a highly significant difference between the high concentration group(67.75%±7.65%,46.5%±10.62%)and the medium concentration group(60.90%±5.87%,59.27%±7.82%)(P<0.01).There was statistical significance in normal mouse serum MLT content in the high concentration group(P<0.05).There was no effect on serum VIP levels in normal mice;no effect on the morphology of stomach and intestinal tissues of normal mice.The small intestine propulsion rate and gastric residue rate of liquid and semi-solid paste in mice with gastric motility disorders were statistically significant compared to the atropine group,with extremely significant differences(P<0.01).[Conclusions]P.fallax Hemsl water extract has a promoting effect on gastrointestinal motility.One of the specific mechanisms by which P.fallax Hemsl promotes gastrointestinal motility in normal mice may be related to the content of MLT in mouse serum.The mechanism of action in atropine induced gastric paresis mice may be related to the reactivation of M receptors,and the action mechanism of P.fallax Hemsl does not change the original histological basis.It can be inferred that P.fallax Hemsl water extract has a synergistic effect on promoting gastrointestinal motility through other mechanisms,but it is not fully understood and further in-depth research is needed. 展开更多

This paper first proposes that a physical entity such as an electron and a cosmological entity such as a photon belong to two different levels of the Universe. When declaring that space is a vacuum, we are referring to the physical vacuum, and not the cosmological vacuum. The paper propounds that the space we observe is a fabric of cosmological substances. We cannot presume that something fills the emptiness of space. This paper posits that the fab-ric of cosmological substances creates this emptiness to facilitate physical activities such as electromagnetic waves and gravitational pull. Second, the space fabric is a spatial cosmo-logical phenomenon, whereas time is a physical phenomenon operated by a physical entity. The spacetime continuum is created by physical time acquiring the cosmological space fab-ric. The third part of this paper explains the structure and ingredients of the space fabric. The structure itself explains several cosmological phenomena, including electromagnetic waves, gravitation, light, magnetism, dark matter, and dark energy. The philosophical cor-rectness of the paper is validated through the unification of multidisciplinary aspects, and its scientific correctness is validated by its logical consistency with the results of well-known experiments. 展开更多

Happiness, as much a poetic as a philosophical, sociological, and psychological concept, has been, through the ages, at the heart of the needs each individual seeks to fulfil. But today, in a world dominated by technology, driven by productivity and dictated by efficiency, what about Happiness? Does it feature in works of fiction in any significant way? May it not have adopted different guises? ls that "duty of happiness" that Pascal Bruckner was talking about present in the French novel of the 20th-21th centuries? And if it is, has its force strengthened or weakened? This article will discuss the French Novels (of the 20th-21th centuries) that are devoted to or associated with Happiness in a direct or indirect manner. It will contextualize and analyze the transformation of Happiness, within the context of the historical and social events that influenced that period: the Holocaust, consumerism, postmodernism, structural social changes, the various as yet unarticulated new modes of life they created, and so on. To that end, this article will explore the discursive philosophical concept of happiness and its influence on the formation of the French novel. In so doing it will focus on the explicit discourse behind the motifs, the choices made in the process of writing, and the attitudes taken, considering the theme of happiness. Doing so, a significant discussion will be included regarding the paths of happiness, its agents, and the nature of the motifs and metaphors linked to the theme of happiness. The author will also address the dialectical role of the happiness theme in the constitution of an emerging literary discourse reflected in the French novel. By exploring the manifestation of the dogmas, ideas of the intellectual leaders of the 20th century (e.g., Jean-Paul Sartre, Simone De Beauvoir, Albert Camus) as well as the ones of the 21th century (e.g., Pascal Bruckner, Andr6 Comte-Sponville, Gilles Lipovetsky) new insights concerning the hybrid nature of the supposedly "authentic happiness" will be revealed. The author intend to inspect the theme of Happiness around four dialectical axes as a relevant ethical basis for delimiting the various fields of research: (1) Love, passion, and conjugality; (2) Ageing; (3) "The experience of everydayness"; and (4) "The era of emptiness". Focusing on the narratives, the article takes into account their specificity in the four distinct fields, all connected to existential and ethical issues, Finally, this article will attempt to analyse the assumed role of literature as a conduit of cultural awareness. 展开更多

Loop quantum gravity is considered to be one of the two major candidates for a theory of quantum gravity. The most appealing aspect about this theory is it predicts that spacetime is not continuous;both space and time have a discrete nature. Simply, space is not infinitely divisible, but it has a granular structure, and time does not flow continuously like a smooth river. This paper demonstrates a review for two missed (unnoted) observations that support the discreteness of the spacetime. The content of this paper does not validate the specific model of quantized geometry of the spacetime which is predicted by the theory itself. Instead, it proves that time does not flow continuously. But it flows in certain, discrete steps, like a ticking of a clock, due to a simple observation which is absence of any possible value of time that can exist between the present and the future. Regarding space, it validates the spatial discreteness, and the existence of spatial granules (space quanta) due to a simple observation which is the existence of the origin position in a coordinates system. All of this is achieved by reviewing the concept of discreteness itself, and applied directly to the observations. 展开更多

The new view denies the existence of fundamental particles in matter, and instead states that any particle and matter is a dynamic superposition of three natural elements, motion, force, and emptiness. This paper proposes a new theory of the structure of matter and the unification of the four forces. A correct understanding of the logic of material structure will enable atomic energy and nuclear physics to generate new manufacturing ideas. The dissertation expounds the natural distribution of dynamics and forces in space and the new deterministic theory of dynamic relationship. This theory solves problems such as the unity of the four forces and the dynamic laws of the material structure. In practical applications, it can provide new theoretical guidance for industrial manufacturing such as nuclear energy, fusion engineering, new energy, new materials, battery energy storage, new-generation reactors, etc., and then adopt effective means in line with the laws of natural power to make the substances needed by human beings. The supply of resources and energy is perfectly satisfied. Applying this theoretical model of material structure to all aspects of the manufacturing industry will surely open up a new era of material civilization for human beings. 展开更多

He then developed integral equations for the probabilities of emptiness and overflow. These equations are difficult to solve numerically;thus, approximations have been proposed that discretize the input.

AIM: To study the effects of low-dose amitriptyline (AMT) on gastrointestinal function and brain-gut peptides in healthy Chinese volunteers. METHODS: This was a double-blind, randomised, placebo-controlled, two-period cross-over trial. Twentyeight healthy volunteers were randomised and administered 1-wk treatments of AMT (12.5 mg tid) or placebo. Before and during the final two days of treatment, gastric emptying, proximal gastric accommodation and visceral sensitivity were measured by drinkingultrasonography test; the orocecal transit time (OCTT) was measured by lactulose hydrogen breath test, and fasting blood was collected. Plasma levels of ghrelin, motilin and neuropeptide Y (NPY) were measured by enzyme-linked immunosorbent assay kits.RESULTS: AMT slowed the OCTT (109.2 ± 29.68 min vs 96.61 ± 23.9 min, P = 0.004) but did not affect liquid gastric emptying and had no effect on proximal gastric accommodation. AMT resulted in decreases in the visual analogue scale (VAS) for difficulty in drinking 600 and 800 mL of water (3.57 ± 0.94 vs 2.98 ± 0.85, 5.57 ± 0.82 vs 4.57 ± 0.98, P < 0.01 for both), although it had no significant effect on the VAS for difficulty in drinking 200 mL and 400 mL of water. AMT significantly increased the plasma ghrelin level (442.87 ± 176.79 pg/mL vs 526.87 ± 158.44 pg/mL, P = 0.04) and the neuropeptide-Y level (890.15 ± 131.46 pg/mL vs 965.64 ± 165.63 pg/mL, P = 0.03), whereas it had no effect on the MTL level. CONCLUSION: Low-dose AMT could slow OCTT, make the stomach less sensitive and increase the plasma levels of ghrelin and NPY. Thus, we recommend the use of low-dose AMT for functional gastrointestinal disorders. 展开更多

AIM: To investigate the relationship between gastric dysmotility,gastrointestinal hormone abnormalities, and neuroendocrine cells in gastrointestinal mucosa in patients with functional dyspepsia (FD).METHODS: Gastric emptying was assessed with solid radiopaque markers in 54 FD patients, and the patients were divided into two groups according to the results, one with delayed gastric emptying and the other with normal gastric emptying. Seventeen healthy volunteers acted as normal controls. Fasting and postprandial plasma levels and gastroduodenal mucosal levels of gastrointestinal hormones gastrin, somatostatin (SS) and neurotensin (NT)were measured by radioimmunoassay in all the subjects.G cells (gastrin-producing cells) and D cells (SS-producing cells) in gastric antral mucosa were immunostained with rabbit anti-gastrin polyclonal antibody and rabbit anti-SS polyclonal antibody, respectively, and analyzed quantitatively by computerized image analysis.RESULTS: The postprandial plasma gastrin levels, the fasting and postprandial plasma levels and the gastric and duodenal mucosal levels of NT were significantly higher in the FD patients with delayed gastric emptying than in those with normal gastric emptying and normal controls. The number and gray value of G and D cells and the G cell/D cell number ratio did not differ significantly between normal controls and the FD patients with or without delayed gastric emptying.CONCLUSION: Our findings suggest that the abnormalities of gastrin and NT may play a role in the pathophysiology of gastric dysmotility in FD patients, and the abnormality of postprandial plasma gastrin levels in FD patients with delayed gastric emptying is not related to the changes both in the number and gray value of G cells and in the G cell/D cell number ratio in gastric antral mucosa. 展开更多

AIM To establish a modified B-ultrasound method of measuring the antral section only to assess gastric motility in healthy people,and evaluate its application in guiding enteral nutrition(EN) in critically ill patients. METHODS First,30 healthy volunteers were selected. The modified B-ultrasound method and the traditional B-ultrasound method were applied to assess gastric function. The correlation of indices of gastric function between the two groups was analyzed statistically. In addition,64 critically ill patients were selected,and the modified B-ultrasound method and the gastric juice withdrawal method were applied to guide the implementation of EN. Daily caloric value,the time required to achieve complete EN,ICU stay,hospitalization time,and serum prealbumin and albumin levels were recorded and compared between the two groups. Kaplan-Meier survival curve was used to compare the complications of EN between the two groups. RESULTS In healthy subjects,there was a good correlation among gastric emptying time,antral contraction frequency andantral motility index between the two groups(r = 0.57,0.61 and 0.54,respectively). The study on critically ill patients also revealed that a better effect of EN was achieved in the modified B-ultrasound method group,in which patients had shorter ICU stay and hospitalization time and higher levels of serum prealbumin and albumin. The Kaplan-Meier survival analysis revealed that the improved B-ultrasound method was associated with significantly fewer EN complications(P = 0.031).CONCLUSION The modified B-ultrasound method can provide a good real-time assessment of gastric function and has a better effect than the traditional method in guiding EN in critically ill patients. 展开更多
