乳酸以往被视为不具备生物学功能的代谢废物。随着人们对乳酸的深入研究,发现乳酸有多种作用。乳酸化修饰是近期发现一种与乳酸有关的蛋白质翻译后修饰过程。乳酸化修饰主要有两种,一种是与乳酸相关的直接修饰,另外一种是与丙酮酸相关的间接修饰。这两种乳酸化修饰均可能受到糖酵解、乳酸转运与堆积、蛋白质串扰以及神经系统等多方面的调控。乳酸化修饰可以通过直接或间接修饰组蛋白或非组蛋白,从而在肿瘤组织的代谢重编程、增殖、迁移及免疫逃逸中发挥着重要作用。乳酸化修饰的深入研究,有望为肿瘤的诊断和治疗开辟新的路径。因此,为了明确乳酸化修饰在肿瘤方面的研究进展,本文就蛋白乳酸化修饰的分子机制及其在肿瘤中作用的研究进展作一综述。

       Lactic acid was previously regarded as a metabolic waste product with no biological function. As lactic acid has been intensively studied, it has been found to have multiple roles. Lactation modification is a recently discovered protein post-translational modification process related to lactic acid. There are two main types of lactation modification：one is direct modification related to lactic acid and the other is indirect modification related to pyruvate. Both types of lactation modification may be regulated by various aspects such as glycolysis, lactate transport and accumulation, protein crosstalk, and the nervous system. Lactation modification can play an important role in metabolic reprogramming, proliferation, migration, and immune escape of tumor tissues by directly or indirectly modifying histones or non-histone proteins. The in-depth study of lactation modification is expected to find new pathways for tumor diagnosis and treatment. Therefore, in order to clarify the research progress of lactation modification in tumors, this paper presents a review on the molecular mechanism of protein lactation modification and the research progress of its role in tumors. 

炎症性肠病（IBD）作为一种慢性、易复发的炎症性疾病,被世界卫生组织归类为现代医疗领域的难治性疾病之一。其确切发病机制尚不清晰,目前主要认为与肠菌失衡触发宿主过度的肠黏膜免疫反应,进而在遗传易感性的个体中引发肠黏膜的损伤有关。目前,尚无特效的靶点能治愈IBD。过氧化物酶体增殖物激活受体（PPARs）作为核受体超家族的一员,在机体的生长发育、炎症调控以及代谢过程中扮演着重要角色,且被视为治疗包括IBD在内的多种疾病的重要潜在靶点,并被认为与肠道菌群关系密切。文章旨在探讨PPARs与肠道菌群的关系在IBD中的作用,从而挖掘IBD新的潜在诊疗靶点,开发新的治疗策略,为临床上IBD的诊断和治疗提供新的思路和方法。

Inflammatory bowel disease（IBD）,characterized as a chronic and recurrent inflammatory condition,is classified by the World Health Organization as one of the intractable diseases in modern medicine．The precise pathogenesis of IBD remains unclear,but current research widely believes that it is closely related to dysbiosis of the gut microbiota．Imbalance in the gut flora triggers an excessive immune response in the host’s intestinal mucosa,leading to mucosal damage in genetically susceptible individuals．To date,no specific targets have been identified that can cure IBD．Peroxisome proliferator-activated receptors（PPARs）,as members of the nuclear receptor superfamily,play significant roles in growth and development,inflammation regulation,and metabolic processes．They are regarded as potential effective targets for treating various diseases,including IBD,and are closely related to the gut microbiota．This review aims to discuss the progress in understanding the role of the relationship between PPARs and gut microbiota in IBD,so as to find new potential targets for the diagnosis and treatment of IBD,develop new treatment strategies,provide new ideas and methods for the diagnosis and treatment of IBD in clinical practice．

慢性萎缩性胃炎是常见的胃癌前病变,不仅治疗过程漫长,治疗难度大,而且患者依从性欠佳。不仅会对患者的生理、心理健康和生活质量造成严重不良的影响,还会给患者家属造成负担,成为临床上不可忽视的难题。但是本病发病机制目前尚未完全明确,临床治疗还未达成共识。文章综述了近10年基于Hedgehog信号通路的中医药干预慢性萎缩性胃炎的研究概况。中医药调控Hedgehog信号通路辨证论治是治疗慢性萎缩性胃炎的一种独具特色的疗法,近年来有关基于Hedgehog信号通路的中医药干预治疗慢性萎缩性胃炎的报道越来越多。文章主要通过遵循疾病本虚标实的病性,以脾胃虚弱为本,瘀血、气滞、湿热、痰浊等为标,探讨选方治疗对慢性萎缩性胃炎的影响,认为中医药联合Hedgehog信号通路实行现代化发展能够有效干预治疗慢性萎缩性胃炎,以期为进一步临床研究与应用提供参考。

Chronic atrophic gastritis,a common precancerous lesion of gastric cancer,requires a long-term treatment and is difficult to cure．Therefore,it usually leads to decreased patient compliance．It will not only have a serious adverse impact on the patient’s physical and mental health and quality of life,but also cause a burden to the patient’s family,which has become a difficult problem that can not be ignored clinically．However,the pathogenesis has not yet been totally clarified,not to mention a consensus on the clinical treatment．This paper reviews the research revolving around Chinese medicine intervention in chronic atrophic gastritis based on the Hedgehog signaling pathway in the last decade．It’s creative therapy of chronic atrophic gastritis that utilizing Traditional Chinese Medicine to regulate and control Hedgehog signaling pathway,which has been increasingly reported in recent years．This paper is based on “deficiency in origin” and “excess in superficiality” principle．Concretely,spleen-stomach vacuity is characterized by deficiency in origin,and excess in superficiality manifests blood stasis,qi stagnation,dampness-heat and phlegm turbidity as excess in superficiality．By this way,the paper explores the effect of prescription selection on chronic atrophic gastritis．It is believed that the modern therapy that combines traditional Chinese medicine with Hedgehog signaling pathway can tackle chronic atrophic gastritis,thus providing a reference for further clinical trials and practices．

Objective To explore the application analysis of failure mode and effect analysis（FMEA）risk management model in digestive endoscopy diagnosis treatment and nursing．Methods A total of 368 patients who underwent painless endoscopic diagnosis and treatment at Henan Provincial People’s Hospital from July 2021 to December 2022 were selected．According to the order of enrollment,patients enrolled in March 2022 and before were selected as the control group（n=171）,and routine nursing management was implemented．The patients enrolled after March 2022 were in the observation group（n=197）．In addition to the control group,a nursing risk management model based on FMEA was added to compare the nursing quality of the two groups of patients．Results The risk priority number（RPN）values of each link in the observation group showed a significant improvement compared to that before intervention．The total RPN score decreased from 1 044 points to 336 points,and the incidence of adverse events in the observation group was lower than that in the control group（17.3% vs 33.3%,P<0.05）．The satisfaction of the observation group with medical staff was higher than that in the control group（92.9% vs 85.4%,P<0.05）．The waiting time required by the observation group was lower than that in the control group[（35.68±7.29）min vs（44.27±8.65）min,P<0.05]．Conclusion sThe FMEA risk management model can effectively improve the nursing quality in painless endoscopic diagnosis and treatment．

目的 探讨责任制助产护理模式配合体位管理对高龄产妇分娩方式及产程的影响。方法 选择2023年6月—12月医院接收的高龄产妇68例进行研究，按照护理方式分为两组各34例，对照组为常规助产护理，观察组为责任制助产护理模式配合体位管理，比较两组分娩方式、产程、疼痛程度及护理满意度。结果 观察组阴道分娩率为76.47%（26例），高于对照组52.94%（18例），剖宫产率为8.82%（3例），低于对照组29.41%（10例）（χ2分别为4.121、4.660，均P＜0.05）。观察组第一产程（6.25±0.50）h、第二产程（0.79±0.21）h、总产程（7.15±0.63）h、宫口开大3 cm、10 cm时的疼痛程度（4.12±1.08）分、（6.29±1.25）分明显低于对照组（7.01±0.62）h、（0.96±0.30）h、（8.11±1.07）h、（7.84±1.45）分、（9.09±0.74）分（t分别为5.563、2.706、4.508、11.997、11.239，均P＜0.05）。观察组的护理满意度为97.06%（33例），比对照组的76.47%（26例）高（χ2=4.610，P=0.031）。结论 高龄产妇展开责任制助产护理模式配合体位管理可促进自然分娩，并缩短产程，减轻产时疼痛程度，降低剖宫产率，提高护理满意度。

Objective To explore the effect of responsibility midwifery nursing model combined with position management on delivery mode and labor process of elderly parturient．Methods A total of 68 cases of elderly pregnant women admitted to the hospital from June to December 2023 were selected,and they were divided into two groups according to the nursing mode,34 cases in each group．The control group was given routine midwifery nursing,and the observation group was given responsible midwifery nursing mode combined with position management．The methods of delivery,labor process,pain degree and nursing satisfaction of the two groups were compared．Results The vaginal delivery rate was 76.47%（26 cases）in the observation group,which was higher than 52.94%（18 cases）in the control group,and the cesarean section rate was 8.82%（3 cases）in the observation group,which was lower than 29.41%（10 cases）in the control group（χ²=4.121 and 4.660,P=0.042 and 0.030）．The pain degree of the first stage of labor（6.25±0.50）h,the second stage of labor（0.79±0.21）h,the total stage of labor（7.15±0.63）h,the pain degree of the cervical dilation 3 cm,10 cm in the observation group were significantly lower than those in the control group[（7.01±0.62）h,（4.12±1.08）points,（6.29±1.25）points vs （0.96±0.30）h,（8.11±1.07）h,（7.84±1.45）score,（9.09±0.74）score（t=5.563,2.706,4.508,11.997,11.239,P<0.05）．The nursing satisfaction of the observation group was 97.06%（33 cases）,which was higher than 76.47%（26 cases）of the control group（χ²=4.610,P=0.031）．Conclusion sResponsibility midwifery nursing mode combined with position management can promote natural childbirth,shorten the labor process,reduce the pain during labor,reduce the rate of cesarean section,and improve nursing satisfaction in elderly women,which is worthy of promotion．
