BACKGROUND: Amniotic membrane has a unique structure that can block the penetration of certain substances, to ensure normal nutrition supply for the surrounded tissues, and is also characterized by anti-adhesion, good tissue compatibility, mild inflammatory reaction, few fibers and biodegradability. OBJECTIVE: To compare the effects of fresh amniotic membrane and acellular amniotic membrane to prevent adhesion and promote tendon healing during the repair of tendon sheath defects. METHODS: Sixty healthy male leghorn chickens were selected, and the model of tendon injury and tendon sheath defects was established at the third toes. The animal models were then randomly divided into three groups and underwent repair with fresh amniotic membrane (group A), acellular amniotic membrane (group B), and no treatment in control group (group C), respectively. Histological observation and biomechanical analysis of the third toes were performed after repair. RESULTS AND CONCLUSION: (1) Histological observation. Congestive edema and inflammatory response were found in all animals at 2 weeks after repair, but mildest in the group A and severest in the group C. These inflammatory responses gradually alleviated over time in the three groups. At 12 weeks after repair, the new tendon sheath formed in all the animals, which was more mature than that at 4 weeks after repair. The synovial cells on the surface of the tendon sheath were arrayed tidily with dense structure in the groups A and B, but in the group C, the synovial cells were distributed disorderly with loose structure and prominent fibrous tissues. (2) Biomechanical analysis. Tendon sliding distance in the groups A and B was significantly larger than that in the group C at 4, 8, 12 weeks after repair (P < 0.05), but there were no significant difference in the distance between the groups A and B (P > 0.05). At 4 and 8 weeks after repair, the maximum tensile strength was largest in the group A, sequentially followed by group B and group C (P < 0.05), but there were no significant difference among the three groups at 12 weeks after repair (P > 0.05). To conclude, both fresh amniotic membrane and acellular amniotic membrane can promote tendon healing and prevent the adhesion of tendon through tendon sheath reconstruction, but the fresh amniotic membrane is preferred to promote early tendon healing compared with acellular amniotic membrane.

Kangfu Xiaoyan Suppository is widely used in the treatment of gynecological inflammatory diseases. Long-term clinical application and a certain amount of research evidences show that Kangfu Xiaoyan Suppository can alleviate the clinical symptoms of pelvic inflammatory diseases,reduce the recurrence rate,and relieve sequelae,with a better safety and economic characteristics. As a type of nationally protected traditional Chinese medicine and type B medicine included in medical insurance,it has been selected as a Chinese patent medicine for rectal administration. It was included in the Guidelines for diagnosis and treatment of common gynecological diseases of traditional Chinese medicine published by the Chinese Academy of Traditional Chinese Medicine in 2012,the Pelvic inflammatory diseases diagnosis and treatment guidelines issued by the Infectious Diseases Collaborative Group of the Obstetrics and Gynecology Branch of the Chinese Medical Association in 2014,and the group standard of Single use of traditional Chinese medicine/combined antibiot guidelines for clinical practice-pelvic inflammatory diseases of the Chinese Academy of Traditional Chinese Medicine in 2017. To further enhance clinicians' understanding of the drug and better guide its rational clinical use,experts from the field of gynecology of traditional Chinese and Western medicine were invited to develop and compile this expert consensus. This consensus takes full account of clinical evidences and expert clinical experience,and form recommendations for clinical problems based on evidences and consensus recommendations for clinical problems without evidence by nominal grouping method. The expert consensus is mainly formed in the consideration of six factors: quality of evidence,economy,efficacy,adverse reactions,patient acceptability and others. Based on clinical research evidences and expert experience,this consensus provides a preliminary reference for the clinical use of the drug in a concise and clear format. However,evidence-based support is still required in a large number of high-quality studies,and this consensus will be revised in the future according to new clinical problems and the update of evidence-based evidence in practical application.

BACKGROUND: Catheter-based pulmonary vein isolation (PVI) is an effective and well-established intervention for symptomatic paroxysmal atrial fibrillation (PAF). Nevertheless, late recurrences of atrial fibrillation (LRAF) occurring during 3 to 12 months are common, and the underlying mechanisms remain elusive. Circular RNAs (circRNAs) in atrial tissue have been linked to the pathophysiological mechanisms and progression of PAF in a few studies. However, their expression patterns in peripheral blood and regulatory function in LRAF are not clear. METHODS: In the present study, the expression profile of circulating circRNAs in three paired nonvalvular PAF patients with or without LRAF was investigated by high-throughput sequencing and validated by quantitative real-time polymerase chain reaction (qRT-PCR). Bioinformatics analyses, including Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and circRNA/miRNA regulatory network, were performed to predict the functions and potential regulatory roles of differentially expressed (DE) circRNAs. RESULTS: A total of 12,834 circRNAs, comprising 5,491 down-regulated and 7,343 up-regulated circRNAs, were found to be DE in blood smaples from the two groups in peripheral blood between LRAF and non-recurrence control individuals. The most enriched GO categories in terms of molecular function, biological process, and cellular component features were catalytic activity, cellular metabolic process, and intracellular part, respectively. The KEGG enrichment study revealed that the most important metabolic process controlled by DE circRNAs is endocytosis. In the circRNA/microRNAs interaction network, four up-regulated circRNAs (hsa_circ_0002665, hsa_circ_0001953, hsa_circ_0003831, and hsa_circ_0040533) and one down-regulated circRNA (hsa_circ_0041103) were predicted to play potential regulatory roles in the pathogenesis of LRAF. CONCLUSIONS This investigation discovered the expression pattern of circulating circRNAs that is indicative of PAF late recurrence, which may serve as risk markers or therapeutic targets for LRAF after PVI.
