Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder in women of childbearing age, which can cause metabolic disorders, cardiovascular disease, ovarian cancer, uterine cancer and other complications, seriously endangering the health of the body. China has become one of the countries with the fastest increasing prevalence of PCOS, but its complex pathogenesis leads to highly heterogeneous clinical manifestations, making it difficult to completely cure. Therefore, clarifying the potential pathogenesis of PCOS is of great significance for early clinical screening, diagnosis, treatment, and prognosis. Recent studies have shown that long noncoding RNA (lncRNA) plays a dual role in the pathogenesis of PCOS and is a potential novel biomarker and intervention target. The characteristics of multi-component, multi-target, and multi-pathway action in Traditional Chinese Medicine (TCM) are consistent with the biological properties of lncRNA, which have diverse types, dual roles, and diverse locations. However, research on lncRNA mediated PCOS and how TCM can improve PCOS by regulating lncRNA is relatively scattered, which is not conducive to the recognition of its clinical value. Therefore, this article provides a systematic review of the dual regulatory mechanism, clinical value, and TCM intervention research of lncRNA in the occurrence and development of PCOS, aiming to clarify how lncRNA affects the occurrence and development of PCOS and potential treatment strategies, in order to provide new ideas for the clinical prevention and treatment of PCOS.

Objective:To investigate the safety and efficacy of a modified radiofrequency ablation（RFA）treatment method for primary great saphenous vein varicose.Methods:Clinical data of 90 patients with primary great saphenous vein varicose treated with ultrasound-guided RFA from January 2021 to April 2024 in the Ultrasound Department of the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. Among them，45 patients were treated with traditional RFA treatment method（traditional group）and 45 patients were treated with improved RFA treatment method（improved group）. Number of punctures，operation time，foam hardener dosage，intraoperative and postoperative complications were recorded in the two groups. The preoperative and postoperative venous clinical severity score（VCSS）and chronic venous insufficiency questionnaire（CIVIQ-14）were compared. The closure rate and recurrence rate of great saphenous vein varicose were followed up and the efficacy of the two methods were analyzed.Results:The success rate of the improved group and the traditional group was 100%.The number of punctures in the improved group was less than those of the traditional group［1（1，1） vs. 2（2，3）， Z = -7.431， P<0.001］，and the operation time of the modified group was shorter than that of the traditional group［（15.89 ± 3.63）min vs.（30.91 ± 5.58）min， t=-15.145， P<0.001］，the average volume of lauryl foam was lower than that of the traditional RFA group［（7.96 ± 2.36）ml vs.（15.69 ± 2.89）ml， t=-13.892， P<0.001］. The incidence of complications was similar between the two groups，with no statistical significance（all P>0.05）. Postoperative VCSS and CIVIQ-14 scores were significantly improved compared with before（all P<0.001），with no statistical significance between the two groups（all P>0.05）. At 12 months after the operation，there was no significant difference in the closure rate of the saphenous vein between the improved group and the traditional group（ P>0.05），and the recurrence rate of varicose veins in both groups was 0. Conclusions:This modified RFA treatment method for the treatment of lower extremity varicose veins is minimally invasive，safe，and has the same efficacy as the traditional RFA treatment method. Compared with the traditional RFA treatment method，the modified RFA treatment method has the advantages of convenient operation，less puncture times and shorter operation time，and is worthy of clinical promotion.

Objective To explore the feasibility and safety of ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer.Methods Totally 84 patients who underwent ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer were enrolled,and the technical success rate,complete ablation rate,complication rate,pain relief rate and survival time,etc.were observed.Results The median age of 84 cases was 61.5 years.Totally 86 tumors,including 44.19％(38/86)at the head/neck and 55.81％(48/86)at the body/tail of pancreas were detected,and a total of 85 ablation sessions were performed with the median ablation energy applied per tumor of 9.90(1.08,21.60)kJ and the complete ablation rate of 42.86％(36/84).The technical success rate was 100％(85/85).Thirty-nine complication events occurred in 25 cases,no ablation-related death.Among 34 patients underwent ablation mainly for pain symptoms,the pain score decreased from(6.22±1.12)points before treatment to(1.94±1.64)points after treatment(P＜0.001).During 6.8(3.3,12.9)months' follow-up,the mean survival time was(8.5±6.7)months,and all 47 patients died due to tumor progression.Conclusion Ultrasound-guided percutaneous microwave ablation was safe and feasible for unresectable pancreatic cancer.
