Patients with alcoholic cirrhosis often experience varying degrees of malnutrition， and the patients with malnutrition are more susceptible to complications such as infections and ascites， which may lead to a poor prognosis. Therefore， it is particularly important to conduct nutritional risk screening for patients in clinical practice， and appropriate nutritional assessment tools should be used to evaluate the nutritional status of patients and develop individualized nutritional supplementation regimens， thereby promoting disease recovery and improving prognosis and quality of life. This article elaborates on the specific methods for nutritional screening， assessment， and management in patients with alcoholic cirrhosis and points out that systematic nutritional screening and assessment can help to identify the patients with malnutrition in the early stage and provide timely intervention. Individualized nutritional supplementation regimens should be adjusted based on the conditions of patients， so as to meet their nutritional needs， promote the recovery of liver function， improve overall health status， and enhance long-term quality of life.

Objective To assess the clinical value of multimodal ultrasound score for assessment of endometrial receptivity among patients with polycystic ovary syndrome (PCOS), and to provide guidance for improving pregnancy outcomes among PCOS patients. Methods A total of 48 PCOS patients admitted to Jiangning Hospital Affiliated to Nanjing Medical University between January and December 2023 were enrolled as the case group, while 50 healthy women of childbearing age received ovulation monitoring at the same hospital during the same period served as the control group. Subjects received two-dimensional grayscale ultrasound during the implantation window (19 to 23 days of the menstrual cycle) for measurement of endometrial thickness, Gonen classification, and endometrial peristalsis. Two-dimensional color Doppler ultrasound was used for assessment of endometrial blood flow and three-dimensional ultrasound was used for assessment of endometrial volume and vascularization flow index (VFI). The endometrium multimodal ultrasound scores were estimated, and various parameters were compared between the two groups. The diagnostic performance of these parameters for PCOS was evaluated with receiver operating characteristic (ROC) curves. Results The age of subjects in the case group ranged from 20 to 38 years, with a mean age of (28.20 ± 2.82) years, and their body mass index (BMI) ranged from 21.23 to 29.11 kg/m², with a mean BMI of (26.25 ± 1.60) kg/m². The age of subjects in the control group ranged from 22 to 38 years, with a mean age of (28.10 ± 1.99) years, and their BMI ranged from 21.33 to 29.03 kg/m², with a mean BMI of (26.10 ± 1.78) kg/m². There were no significant differences between the case and control groups in terms of mean age, BMI, estradiol, and testosterone (t = 0.218, 0.422, 0.010, and 0.221; all P > 0.05). The endometrial thickness, endometrial volume, and VFI were significantly higher in the control group than in the case group (t = 4.838, 4.978, and 7.115; all P < 0.05). There were significant differences between the two groups in terms of endometrial classification, endometrial peristalsis pattern, and endometrial and sub-endometrial blood flow (Z = −4.136, −4.048, and −3.884; all P < 0.05). The scores of endometrial classification, endometrial peristalsis, endometrial and sub-endometrial blood flow, endometrial volume, VFI, and multimodal ultrasound were significantly lower in the case group than in the control group (t = 4.539, 4.449, 4.205, 3.209, 5.206, and 4.495; all P < 0.05). No significant difference was detected in the endometrial thickness score between the two groups (t = -0.149, P = 0.882). The areas under the ROC curves for endometrial thickness, endometrial volume, VFI, and multimodal ultrasound scores in diagnosis of PCOS were 0.753, 0.747, 0.809, and 0.858, respectively. Conclusion Multimodal ultrasound score provides a comprehensive assessment of the endometrium, and is effective in the assessment of endometrial receptivity, which may provide a reference for guiding pregnancy planning in PCOS patients.

OBJECTIVE: To evaluate the efficacy and safety of denosumab in the treatment of prostate cancer with bone metastases. METHODS: Relevant studies were retrieved from PubMed, EMBASE, Cochrane, Web of Science, Sinomed , CNKI and Wanfang databases. The Cochrane risk-of-bias assessment tool was used to evaluate the quality of included studies, and relevant data were extracted. meta-analysis was performed using RevMan 5.4 and RStudio software, and forest plots were generated. RESULTS: Six randomized controlled trials (RCTs) were included. Compared with the control group, denosumab significantly reduced the risk of skeletal-related events (HR=0.78, 95% CI: 0.62-0.93). In terms of safety, denosumab did not increase the risk of total adverse events, severe adverse events and the adverse events higher than CTC grade 3. CONCLUSION Denosumab can delay the time to first skeletal-related event with good safety. However, due to the limitations of this study, further high-quality, large-sample, multicenter RCTs are needed to confirm these findings.

OBJECTIVE: To explore the potential effects and mechanisms of Liang-Ge-San (LGS) for the treatment of acute respiratory distress syndrome (ARDS) through network pharmacology analysis and to verify LGS activity through biological experiments. METHODS: The key ingredients of LGS and related targets were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform. ARDS-related targets were selected from GeneCards and DisGeNET databases. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed using the Metascape Database. Molecular docking analysis was used to confirm the binding affinity of the core compounds with key therapeutic targets. Finally, the effects of LGS on key signaling pathways and biological processes were determined by in vitro and in vivo experiments. RESULTS: A total of LGS-related targets and 496 ARDS-related targets were obtained from the databases. Network pharmacological analysis suggested that LGS could treat ARDS based on the following information: LGS ingredients luteolin, wogonin, and baicalein may be potential candidate agents. Mitogen-activated protein kinase 14 (MAPK14), recombinant V-Rel reticuloendotheliosis viral oncogene homolog A (RELA), and tumor necrosis factor alpha (TNF-α) may be potential therapeutic targets. Reactive oxygen species metabolic process and the apoptotic signaling pathway were the main biological processes. The p38MAPK/NF-κ B signaling pathway might be the key signaling pathway activated by LGS against ARDS. Moreover, molecular docking demonstrated that luteolin, wogonin, and baicalein had a good binding affinity with MAPK14, RELA, and TNF α. In vitro experiments, LGS inhibited the expression and entry of p38 and p65 into the nucleation in human bronchial epithelial cells (HBE) cells induced by LPS, inhibited the inflammatory response and oxidative stress response, and inhibited HBE cell apoptosis (P<0.05 or P<0.01). In vivo experiments, LGS improved lung injury caused by ligation and puncture, reduced inflammatory responses, and inhibited the activation of p38MAPK and p65 (P<0.05 or P<0.01). CONCLUSION LGS could reduce reactive oxygen species and inflammatory cytokine production by inhibiting p38MAPK/NF-κ B signaling pathway, thus reducing apoptosis and attenuating ARDS.

Acute respiratory distress syndrome (ARDS) is a common respiratory emergency, but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures. Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS, but the application of hydrogen has flammable and explosive safety concerns. Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance, thus improving ARDS in patients and animal models. Coral calcium hydrogenation (CCH) is a new solid molecular hydrogen carrier prepared from coral calcium (CC). Whether and how CCH affects acute lung injury in ARDS remains unstudied. In this study, we observed the therapeutic effect of CCH on lipopolysaccharide (LPS) induced acute lung injury in ARDS mice. The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable, demonstrating a significant improvement compared to the untreated ARDS model group. CCH treatment significantly reduced pulmonary hemorrhage and edema, and improved pulmonary function and local microcirculation in ARDS mice. CCH promoted mitochondrial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2 (Trx2), improved lung mitochondrial dysfunction induced by LPS, and reduced oxidative stress damage. The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

Objective To observe the changes in the subfoveal choroidal thickness(SFCT)of children and adoles-cents with different refractive states using optical coherence tomography angiography.Methods A total of 171 children and adolescents were followed.They were divided into the lower primary school group(6-8 years old),upper primary school group(9-11 years old),and junior high school group(12-14 years old)according to their age at the time of en-rollment.Dioptric examinations(including best corrected visual acuity,diopter,intraocular pressure,corneal curvature,axial length and SFCT)were performed,data collection was conducted twice in half a year(initial examination and review after half a year),and the eyeball parameters and changes in eyeball parameters after half a year among all groups were compared.Results The axial length and SFCT of subjects had significant differences among all groups(both P＜0.05).In children and adolescents,the axial length gradually lengthened and SFCT gradually thickened with age,while intraocular pressure and corneal curvature were not associated with age(both P＞0.05).In the initial examination and review after half a year,there was no significant difference in intraocular pressure,corneal curvature and SFCT of subjects with differ-ent refractive states in all groups(all P＞0.05),while the axial length of myopic subjects was greater than that of non-my-opic subjects in all groups(all P＜0.05).In the review after half a year,the SFCT of non-myopic subjects in the lower pri-mary school group and upper primary school group was significantly thickened(P＜0.001,P=0.003),while there was no significant difference in SFCT of myopic subjects in all groups compared with the value half a year ago(all P＞0.05).The axial length of all subjects showed a positive correlation with the SFCT in the initial examination and review after half a year(r=0.354,0.228,P＜0.05).Conclusion Myopia affects the increase in SFCT in children and adolescents.

AIM:To investigate the effect and mechanism of velvet antler polypeptide(VAP)on premature ovarian failure induced by cisplatin(DDP)in rats.METHODS:Female rats with normal estrous cycle were randomly di-vided into the control,model,and VAP groups,with 10 rats in each group.Premature ovarian failure was induced in the model and VAP groups by intraperitoneal injection of DDP(4 mg·kg-1·d-1)for 20 consecutive days,and the VAP group was treated with VAP(400 mg·kg-1·d-1)for 20 consecutive days.Hematoxylin and eosin(HE)staining was used to ob-serve the morphological manifestations of the ovary,and the number of developing follicles at all levels was counted.En-zyme-linked immunosorbent assay(ELISA)was performed to detect serum estradiol(E2),follicle-stimulating hormone(FSH),and anti-Mullerian hormone(AMH)levels.The levels of glutathione(GSH)and malondialdehyde(MDA)in ovarian tissues were detected by biochemical methods.The level of reactive oxygen species(ROS)in ovarian tissue was detected by the probe labeling method.Prussian blue staining was performed to observe the iron accumulation in ovarian tissue,as well as the ferrous ion(Fe2+)level was detected by Fe2+content analysis kit.Immunohistochemistry and West-ern blot analysis were performed to detect the expressions of solute carrier family 7 member 11(SCL7A11),glutathione peroxidase 4(GPX4),and acyl-CoA synthetase long-chain family member 4(ACSL4)in the ovarian tissue.The fertility of rats was monitored in each group.RESULTS:Compared with control group,the model group showed ovarian atrophy,iron accumulation(P<0.01),reduced development of follicles at all levels and total follicles(P<0.05),increased atretic follicles(P<0.01),reduced litter size(P<0.01),decreased serum E2 and AMH levels(P<0.01),increased FSH levels(P<0.01),decreased GSH level and SCL7A11 and GPX4 protein expression levels in the ovarian tissue(P<0.01),and increased levels of Fe2+,MDA,and ROS and expression levels of ACSL4(P<0.01).Compared with model group,the VAP group had improvement in these aforementioned changes caused by DDP(P<0.01).CONCLUSION:Treatment with VAP can improve ovarian function,maintain normal follicle development,and improve fertility in cisplatin-induced premature ovarian failure rats,and the mechanism may be related to the inhibition of lipid peroxidation and ferroptosis.

Objective To explore the effectiveness of FOCUS-PDCA(find,organise,clarify,understand,select,plan,do,check and act)mode in prevention and treatment of incontinence-associated dermatitis(IAD)in emergency intensive care unit(EICU),and to reduce the incidence of IAD.Methods A pre-post control study design was employed in this study.Inpatients admitted to the EICU of the hospital between 1st January and 31st December 2022 were enrolled as study subjects.A total of 169 patients in EICU between January and June 2022 were assigned as a control group,while 197 patients in EICU between July and December 2022 as an trial group.Patients in the control group received conventional quality management,while those in the trial group were treated with the FOCUS-PDCA mode.The two groups were compared in terms of incidence of IAD,the knowledge,trust and behaviour scores of the nurses,and satisfaction from the communications with nurses before and after implementation of the FOCUS-PDCA mode.Results All patients in the two groups had completed the study.Following the implementation of FOCUS-PDCA mode,patients in the trial group exhibited a significantly decrease in incidence of IAD from 10.06%(trial group)to 1.52%(control group),significant increase of scores on the IAD knowledge,behaviour and satisfaction from communications with the nurses,from(36.07±3.98),(16.56±2.15)and(25.15±5.21),to(38.59±3.72),(18.07±1.66),and(30.67±5.84),respectively(all P<0.05).Conclusion FOCUS-PDCA mode can effectively decrease the incidence of IAD,enhance the IAD knowledge and behaviour of nurses and gain satisfactions from communication with nursing staff and clinical quality,thereby improving therapeutic outcomes.

The gut microbiota of infants is crucial for the establishment and development of immune system tolerance and responsiveness, as well as long-term health.Breast milk, as the only recommended source of nutrition for infants under 6 months old, possesses all the necessary nutrients and functional components for their growth, development, and health promotion.Human milk oligosaccharides (HMOs), as distinctive functional components that distinguish human milk from other mammalian milk, possess natural targeting properties to reach the colorectum in its intact form and are essential for the maturation of the gut microbiota, development of the digestive system and maintenance of the immune system function in infants, providing natural protection for the digestive and immune systems of newborns.This article reviews the latest research on how HMOs affect the development of the immune system and homeostasis in infants, and focuses on the mechanism by which HMOs control the gut microbiota and influence the immune system′s response through the gut microbiota-immune axis.

Ischemic stroke （CIS） refers to ischemic necrosis or softening of localized brain tissue caused by cerebral blood circulation disorders， ischemia and hypoxia. The incidence of CIS is the highest among cerebrovascular diseases. Reduced supply of oxygen and nutrients leads to severe loss of neurons and deficits in brain function in stroke patients. Developing treatments for ischemic stroke remains an important challenge in clinical medicine. The antioxidant N-acetylcysteine （NAC） is a precursor of glutathione， and evidence from animal models of ischemic stroke and some clinical studies suggest that NAC can effectively protect the brain from ischemic damage. In this paper， the mechanism of NAC in CIS is described from various aspects， such as anti-oxidation， inhibition of inflammation， protection of cerebral nerve and mitochondrial function， stabilization of arterial plaque and thrombolytic function， aiming to explore the relationship between NAC and CIS in depth from the basic level， and to provide a theoretical basis for the further application of NAC in the prevention and treatment of patients with ischemic stroke.
