Purpose:
This study aimed to evaluate the long-term efficacy of the ligation of the intersphincteric fistula tract (LIFT) procedure in treating high transsphincteric fistulas.
Methods:
We conducted a retrospective study to evaluate the success rate of LIFT treatment in 82 patients with high transsphincteric fistulas involving at least one-third of the external sphincter. This study was carried out across 2 centers from November 2009 to February 2023.
Results:
All patients underwent successful surgery with a median operative time of 48.9 minutes (range, 20–80 minutes), and no intraoperative or postoperative complications were reported. The median follow-up duration was 85.5 months (range, 4–120 months), with 5 patients (6.1%) lost to follow-up. Treatment was successful in 62 patients, whose symptoms disappeared and both the external opening and the intersphincteric incision completely healed, yielding an overall efficiency rate of 80.5%. There were 15 cases (19.5%) of treatment failure, including 6 (7.8%) that converted to intersphincteric anal fistula and 9 (11.7%) that experienced persistent or recurrent fistulas. Only 1 patient reported minor overflow during the postoperative follow-up, but no other patients reported any significant discomfort. There were no statistically significant differences between patients with surgical success and those with treatment failure in terms of fistula length, history of previous abscess or anal fistula surgery, number of external orifices or fistulas, and location of fistulas (all P>0.05).
Conclusion
LIFT is a safe and effective sphincter-preserving procedure that yields satisfactory healing outcomes and has minimal impact on anal function.

In recent years, the field of genetics has witnessed a burgeoning interest in the non-coding region, an area previously dubbed the"dark matter"of the genome. This once enigmatic domain is now progressively revealing its secrets, emerging as a rich terrain for genetic diagnosis and treatment. This editorial centers on diverse diagnostic analyses and intervention techniques associated with the non-coding region, delving into its significance in the etiology, diagnosis, and treatment of both monogenic and polygenic disorders within the nervous system. In doing so, it offers a comprehensive perspective for the exploration of genetic disorders in the nervous system.

Objective:To explore the RH genotype for a female with RhD(-) blood type and its molecular basis. Methods:A 26-year-old female who had attended the outpatient clinic of the First Affiliated Hospital of Zhengzhou University in August 2019 was selected as the study subject. Peripheral blood samples were collected from the proband and her parents for Rh phenotyping with gel card method. PCR-sequence-based typing (PCR-SBT) and DNA sequencing were used to determine the RHD zygosity and RH genotype of the proband and her parents. Homology modeling of Rh proteins was performed with bioinformatic software, and protein structural alterations caused by the variant was simulated by molecular dynamics. This study was approved by the Medical Ethics Committee of the First Affiliated Hospital of Zhengzhou University (Ethics No. 2023-KY-0870-003). Results:Serological tests showed that the proband and her father both had weakened e antigen of the Rh phenotype. PCR-SBT and DNA sequencing showed that the genotypes of the proband and her parents were dce/ dCE, dce/ DcE and dCE/ DcE, respectively. And the genotypes of the RHD and RHCE of the proband were RHD*01N.01/ RHD*01N.16, RHCE*01.01/RHCE*04, respectively. Protein simulation and molecular dynamics analysis revealed that the ce_16C variant resulted from RHCE* ce (c.48G>C) may alter the structure of intracellular and extracellular loops, mainly affecting the mobility of extracellular loops 2, 6 and intracellular loops 3, 4. Conclusion:Variant of the RHCE* ce allele c. 48G>C probably underlay the weakened e antigen in this proband.

Objective To investigate the potential active ingredients and the mechanism of Coreopsis tinctoria Nutt. in the prevention and treatment of hyperlipidemia. Methods Ultra-high performance liquid chromatography-Quadrupole-Exactive Orbitrap mass spectrometry (UPLC-Q-Exactive Orbitrap MS) was used to qualitatively analyze the fractions and blood components of flavones in Coreopsis tinctoria Nutt. The intersection targets of flavones in Coreopsis tinctoria Nutt. and hyperlipidemia were screened,and the protein-protein interaction network was constructed and analyzed by the STRING 12.0 database. Finally,the gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used for enrichment analysis. Results A total of 25 compounds were detected from the flavones in Coreopsis tinctoria Nutt.,and their structures were identified,including ten chalcones,nine flavanones,four flavonols,one aurone,and one biflavone. The analysis of blood components showed that marein,flavanomarein,okanin,isookanin and 5,7,3',5'-tetrahydroxyflavanone-7-O-β-D-glucopyranoside were the main components of the flavones in Coreopsis tinctoria Nutt. in blood. Network pharmacological GO and KEGG enrichment analysis showed that the flavones in Coreopsis tinctoria Nutt. may regulate phosphatidylinositol 3-kinase/protein kinase B,tumor necrosis factor,hypoxia-inducible factor-1 signaling pathway and other signaling pathways in the regulation and prevention of hyperlipidemia. Conclusion Coreopsis tinctoria Nutt. can prevent and treat hyperlipidemia,and the mechanism may be related to the five blood components of the flavones in Coreopsis tinctoria Nutt.,including marein,flavanomarein,okanin,isookanin and 5,7,3',5'-tetrahydroxyflavanone-7-O-β-D-glucopyranoside.

This article describes the surgical treatment of fecal incontinence. There are many surgical methods for fecal incontinence, and each treatment has its own advantages and disadvantages and indications. The appropriate surgical procedure should be selected according to the patient's history, anatomical structure and severity of incontinence. Injectable bulking agents is suitable for passive fecal incontinence. Sphincteroplasty is suitable for patients with sphincter injury caused by vaginal delivery or surgical trauma. Sacral nerve stimulation and posterior tibial nerve stimulation are relatively conservative methods. Gracilomyoplasty, artificial anal sphincter or magnetic anal sphincter can be used in the treatment of refractory fecal incontinence, but with many complications. Colostomy is the ideal choice for patients who have failed to respond to conservative treatment and cannot undergo these procedures.
