Traditional Chinese medicine （TCM） therapy has unique clinical advantages in the treatment of atrial fibrillation， mainly reflected in five aspects， improving quality of life， enabling early diagnosis and treatment， promoting cardiac rehabilitation， making up for the limitations of Western medicine， and improving the success rate of catheter ablation. However， there is insufficient evidence in current clinical research. Based on the current status of TCM research in the treatment of atrial fibrillation， it is suggested that future studies should focus on standardized research on syndrome differentiation and classification. This can be achieved through clinical epidemiological surveys， expert consensus， and other methods to establish a unified syndrome differentiation and classification standard for atrial fibrillation. Clinical efficacy evaluation indicators should be standardized， and core outcome measures for clinical research on TCM treatment of atrial fibrillation should be developed through systematic reviews， patient interviews， and other methods. Additionally， clinical research design， implementation， and data management should be improved. By leveraging modern information technologies such as artificial intelligence， the scientific and standardized nature of TCM intervention research on atrial fibrillation can be enhanced， ultimately improving the quality of research.

Objective Studies on the expression and location of zinc finger protein A20 (A20) and connective tissue growth factor (CTGF) in liver tissues of patients with chronic hepatitis B were conducted, and the relationship between them and liver fibrosis was determined by FibroScan. Methods Studies on A20 and CTGF in liver tissues of 160 patients with chronic hepatitis B were conducted in accordance with the stage of pathological fibrosis and inflammation of the liver, and quantitative immunohistochemistry test was conducted, and statistical analysis was conducted by FibroScan. Results The expressions of A20 and CTGF in liver tissues increased with the aggravation of liver pathological fibrosis and inflammation, and there were significant differences between each stage and the control group (P<0.05), and there were significant differences between adjacent groups (P<0.05). Studies have shown that FibroScan increases along with pathological fibrosis and inflammation in the liver. There are significant differences between the stage and the control group (P<0.05), and no significant differences between the adjacent groups (P>0.05). There was positive correlation between liver A20 and CTGF, r=0.796 (P<0.05). Conclusions In patients with chronic hepatitis B, A20, CTGF and FibroScan are positively correlated with the degree of liver fibrosis, and A20 and CTGF are also positively correlated with the degree of liver inflammation, which can be used as indicators to evaluate the degree of liver inflammation and fibrosis, and further guide the anti-inflammatory and anti-fibrosis treatment of patients.

Severe asthma stands as a formidable contributor to both mortality and morbidity of patients suffering asthma, casting substantial social and economic shadows on communities. As our understanding of asthma's pathophysiology deepens, a beacon of hope emerges in the form of biological targeted therapies, offering a promising avenue for the management of this challenging condition. These therapies, by precisely inhibiting or modulating pivotal molecules in the inflammatory cascade, offer potential benefits in symptom alleviation, lung function enhancement, and risk reduction of acute exacerbations. They signify a paradigm shift in severe asthma treatment. Within the confines of this article, we embark on a systematic exploration of the immunological underpinnings that define severe asthma. By delving into the intricacies of the immune system's role in exacerbating this condition, we aim to offer a comprehensive assessment of both the current landscape and the future prospects of biological therapies. Our objective is to provide a scientifically robust and valuable reference that can guide the individualized treatment of patients grappling with severe asthma.

Diabetic nephropathy(DN)is one of the most important complications of diabetes.Its pathogenesis is com-plex and has not been fully elucidated.Epithelial-mesenchymal transition(EMT)plays an important role in the development of DN.Relevant data show that glycogen synthesis kinase-3β(GSK-3β)participates in the process of EMT through multiple sig-naling pathways and affects the occurrence and progression of DN.This article reviews the research progress of GSK-3β in-volved in EMT in DN.

【Objective】 To evaluate the differential miRNA expression of breast milk exosome in premature and full-term groups, and to analyze the regulatory pathways by bioinformatics, so as to provide guidance and scientific basis for the growth and development of premature infants and the prevention and treatment of related diseases. 【Methods】 From August 2020 to June 2021, breast milk samples from 13 premature (premate group) and 9 full-term infants(full-term group) in the Department of Child Health Care of the Second Affiliated Hospital of Nanjing Medical University were collected to extract exosomes. The miRNAs of two groups of breast milk exosomes were sequenced by high-throughput sequencing. According to the sequencing results, miRNA expression profiles of milk exosome were analyzed. Biological function software was used to carry out GO and KEGG pathway analysis of differential miRNA. 【Results】 The expression of miRNA in human milk exosomes was rich, especially hsa-miR-148a-3p,hsa-let-7b-5p, hsa-let-7g-5p, hsa-miR-22-3p, hsa-miR-99a-5p, hsa-miR-200, hsa-miR-146b-5p and hsa-miR-26a-5p were relatively high expressed in preterm group and full-term group. Differential expression analysis showed that compared with full-term infant breast milk, 7 miRNAs were up-regulated(log2|fold change|=2.803, 2.714, 1.632, 2.360, 1.350, 3.387, 2.137, respectively), and 5 miRNAs were down-regulated(log2|fold change|=-2.553, -2.197, -2.771, -1.395, -1.136, respectively)(|fold change>2|, P<0.05) in breast milk for preterm infants. In these differential expressed miRNAs, down-regulated miR-29b(P=0.001) and up-regulated miR-133a-3p(P=0.004) were associated with inflammation, and up-regulated miR-126-5p(P=0.021) and miR-126-3p(P=0.041) were associated with lipid metabolism. The fatty acid biosynthesis pathway was obviously enriched in preterm group. MiR-7-5p, miR-29b-3p and miR-100-5p played a role in the fatty acid synthesis pathway. 【Conclusions】 Exosomal miRNAs are rich in breast milk, and have significant differences between preterm and full-term infants′ mothers. The differentially expressed miRNA in preterm infants treast milk may be related to inflammation and promote the growth and development of preterm infants through the fatty acid biosynthesis pathway.

Objective To explore the levels of plasma complement factor H(CFH)in peritoneal dialysis(PD)patients and its judging value for prognosis.Methods Eighty-two PD patients followed up by the Department of Nephrology,The Second Affiliated Hospital of Naval Medical University were included in the study.Patients were divided by the CFH levels based on immunoassay turbidimetric detection into low H factor group(＜320 μg/mL,n=41)and high H factor group(＞320 μg/mL,n=41),while 82 healthy individuals matched by gender and age were selected as the healthy control group.The correlation between plasma CFH and laboratory results,complications,and prognosis in PD patients was analyzed over a 3-year follow-up.Results There were no differences between the two groups in terms of gender,age,dialysis duration,urine output,and dialysis adequacy,whereas the plasma albumin,total protein and cholesterol were significantly lower in the low CFH group compared with the patients in the high CFH group(P＜0.05).During the 3-year follow-up,the incidence of peritonitis was significantly higher in the low CFH group than in the high CFH group(P＜0.05).Multivariate regression analysis further confirmed that low CFH level was an independent risk factor for the development of PD associated peritonitis(OR=4.24,95%CI 1.18-15.33).Conclusions Reduced levels of plasma CFH in PD patients might suggest the increased risk of hypoalbuminemia and PD-associated peritonitis.
