Background: According to the statistics of WHO/IARC, cervical cancer (CC) has become the fourth malignant cancer of female worldwide and it is one of the main causes of death of women in developing countries. Purpose: Potential plasma and metabolic biomarkers for CC precancerous lesions and cervicitis were indicated by LC-MS techniques, and their underlying mechanisms and functions were analyzed. Methods: Plasma samples were selected from healthy people (control), low-grade squamous intraepithelial lesions (LSIL), high-grade squamous intraepithelial lesions (HSIL), CC, and post-treatment patients. All polypeptide types and sequences were detected by LC-MS/MS and the results were normalized by using Pareto-scaling. Potential metabolic biomarkers were screened by applying MetaboAnalyst 4.0 software and XCMS software, and analysis of variance and enrichment analysis were performed. Metabolic pathway analysis and functional enrichment analysis were used to further investigate the significance and pathological mechanisms of potential biomarkers. Results: Compared with healthy people, 9 differentially expressed metabolites were screened, 4 of which were up-regulated and 5 were down-regulated. LSIL group screened 7 differentially expressed metabolites, 5 of which were up-regulated and 2 were down-regulated; CC group screened 12 differentially expressed metabolites were screened, of which 9 were up-regulated and 3 were down-regulated. Eight differentially expressed metabolites were screened in the IF group, of which 5 showed up-regulation and 3 showed down-regulation. In functional enrichment analysis, differential metabolism was found to be associated with addition and coagulation cascades. Among all potential biomarkers, 2-amino-3-methyl-1-butanol, L-carnitine, Asn Asn Gln Arg, Ala Cys Ser Trp, Soladulcidine, Ala Ile Gln Arg, 2-amino-3 -Methyl-1-butanol, L-carnitine, Asn Asn Gln Arg, Ala Cys Ser Trp, Soladulcidine, Ala Ile Gln Arg can be used as predictors of precancerous lesions at different stages of CC. Among all biomarkers, 6α-fluoro-11β1,17-dihydroxypren-4-ene-3,20-dione has higher expression in the CC and HSIL groups and lower expression in the treatment group. Conclusion: By applying molecular markers to assess the progression of the disease, the accuracy and specificity of the diagnosis can be improved, which has certain prospects in clinical applications.

Background: Sleep disorder is a commonly reported complication in patients who have undergone a hysterectomy, which increases perioperative complications and delays patient recovery. Several pharmacological and non-pharmacological approaches have been employed to improve the quality of sleep of patients during the postoperative period, but these strategies have certain limitations. Intradermal needle therapy is now among the most common treatments for insomnia in traditional Chinese medicine (TCM).The present study was developed to explore the effects of intradermal needle therapy (as an adjunct to physiotherapy-based treatments for postoperative sleep impairment) on the postoperative sleep quality of patients who have undergone a laparoscopic hysterectomy.Methods: This is a prospective, single-center, single-blind, randomized controlled trial. In total, 80 eligible patients will be randomly allocated to the control and experimental groups at a 1:1 ratio. Random numbers and grouping schemes will be generated using the SPSS 25.0 software package. Following the completion of the laparoscopic hysterectomy procedure, the patients will be returned to the medical ward and undergo authentic or sham intradermal needle therapy as appropriate. For patients in the experimental group, following sterilization, intradermal needles will be inserted into the bilaterally "Shenmen" (HT36) and "Sanyinjiao" (SP6) acupoints; the needles will be replaced after 24 h. False intradermal needles that exhibit similar surface characteristics but lack needles will be employed in the control group. Patients will undergo a single 3-day treatment course. The primary outcome is the Pittsburgh Sleep Quality Index. The secondary outcomes are the 10-Item Short-Form Identity-Consequence Fatigue Scale, the Hospital Anxiety and Depression Scale-Anxiety, and postoperative pain scores, which will be rated using a visual analog scale. Time to postoperative defecation and the duration of hospitalization will also be recorded.Discussion: The present study seeks to examine the efficacy of the intradermal needle as a therapeutic tool for improving the sleep quality of patients after surgery who have undergone a laparoscopic hysterectomy to provide a foundation for future large-scale clinical studies.
