Objective To evaluate the feasibility of multi spiral computed tomography(MSCT)for etiological analysis of patients with pelvic venous congestion syndrome(PVCS).Methods The clinical and imaging data of 134 patients diagnosed with PVCS were analyzed retrospectively.The anatomical etiology of PVCS was analyzed,and the clinical and imaging differences between the two groups with and without vascular variation were compared.Results Among the 134 patients,69 had vascular variation,which included 37 distal hypoplasia of left renal vein(LRV),22 nutcracker phenomenon,6 ovarian vein(OV)variation,2 LRV variation,2 portal hyper-tension,2 pelvic arteriovenous fistula,1 left iliac vein compression syndrome,1 left renal malrotation and 1 left renal arteriovenous fistula.The remaining 65 cases showed no vascular variation.There were statistically significant differences in the left ovarian vein(LOV)diameter and reflux degree between the two groups(t=2.544,P=0.012;χ2=21.797,P<0.001).Patients with vascular varia-tion had wider diameter of LOV and higher degree of reflux.There were no statistically significant differences between the two groups regarding age,symptom,times of pregnancy and delivery and body mass index(BMI)values(P>0.05).Conclusion MSCT can provide important reference value for etiological analysis of PVCS,which is helpful for precise treatment.

In this comprehensive review, we delve into the evolution of drug delivery systems in reproductive medicine with a focus on the emerging role of exosomes, a class of extracellular vesicles. Exosomes offer unique advantages in overcoming these challenges due to their inherent biocompatibility, stability, and ability to facilitate targeted delivery. This review provides a detailed examination of exosome biogenesis and their function in cellular communication, setting the stage for understanding their potential as drug delivery vehicles. We explore the mechanisms through which exosomes can be loaded with small molecule drugs and the benefits they offer over synthetic nanoparticles. The review highlights groundbreaking case studies that illustrate the successful application of exosome-mediated drug delivery in reproductive health, including enhancing fertility treatments, supporting gamete and embryo development, and facilitating maternal-fetal communication. This study aims to provide a precise understanding of how exosomal drug delivery can revolutionize treatments for reproductive health disorders, paving the way for future therapeutic applications. Lastly, we touch upon the promising therapeutic implications of exosomal delivery for proteins and genes, offering a window into future treatments for reproductive health disorders.

Objective: To evaluate the effect of exercise prescription intervention among patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for guiding appropriate physical activity and glycemic control in this population. Methods: In July 2023, T2DM patients managed by two community health service centers in Qingjiangpu District, Huai'an City, Jiangsu Province, were selected as the study participants and randomly assigned divided into a control group and an intervention group. The control group received routine chronic disease management under the basic public health services, while the intervention group, in addition to receiving the same routine chronic disease management, was provided with exercise prescription to guide their physical activity at baseline (T0), after 3 months of intervention (T1), and after 6 months of intervention (T2). Data on weight-related indicators, glycated hemoglobin (HbA1c), and blood lipid were collected through physical examinations and laboratory tests at T0 and after 12 months of intervention (T3). The differences in indicators between the two groups before and after the intervention were analyzed using generalized estimating equations. Results: The intervention group consisted of 197 patients, including 99 males, accounting for 50.25%. The median disease duration was 7.10 (interquartile range, 7.80) years, and 113 patients had suboptimal HbA1c levels, accounting for 57.36%. The control group included 196 patients, including 99 females, accounting for 50.51%. The median disease duration was 6.10 (interquartile range, 7.00) years, and 100 patients had suboptimal HbA1c levels, accounting for 51.02%. Before the intervention, no statistically significant differences were observed between the two groups in gender, educational level, disease duration, pharmacological treatment, smoking, alcohol consumption, and HbA1c levels (all P>0.05). In the intervention group, the proportion of participants engaging in aerobic exercise and strength training increased from 78.17% and 8.12% at T0 to 85.79% and 16.24% at T3, respectively (both P<0.05). The results of the generalized estimating equations revealed significant interactions between group and time for waist-to-hip ratio, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) following the intervention (all P<0.05). A statistically significant difference in waist-to-hip ratio was found between the two groups (P<0.05), with a greater reduction observed in the intervention group compared to the control group. Significant differences in TC and LDL-C levels were noted across different intervention time points (both P<0.05). Specifically, the intervention group demonstrated reductions of 0.35 mmol/L in TC and 0.42 mmol/L in LDL-C from baseline to follow-up (both P<0.05). Conclusion The 12-month exercise prescription intervention can effectively enhance exercise participation and reduce waist-to-hip ratio, TC, and LDL-C levels among patients with T2DM.

Objective To explore the anesthesia management experience in the interventional treatment of pediatric congenital heart diseases (CHD) percutaneously guided by transthoracic echocardiography (TTE) on a mobile operating platform. Methods From March to July 2023, a total of 13 patients from remote areas underwent interventional treatment for CHD on the mobile operating platform of Fuwai Yunnan Cardiovascular Hospital. Patients who received non-tracheal intubation general anesthesia were retrospectively included. Results Eight children who had difficulty cooperating with the surgery (due to young age, emotional tension, crying) received monitored anesthesia care with local anesthesia supplemented by sedative and analgesic drugs while maintaining spontaneous breathing under the monitoring and management of an anesthesiologist (i.e., non-tracheal intubation general anesthesia). Among them, there were 5 males and 3 females, with an age of (6.95±3.29) years and a body weight of (19.50±6.04) kg. Through transthoracic echocardiography, they were diagnosed with atrial septal defect (6 patients), residual shunt after patent ductus arteriosus ligation (1 patient), and severe pulmonary valve stenosis (1 patient). The surgery proceeded smoothly, with satisfactory anesthesia and surgical effects, complete analgesia, and satisfactory postoperative recovery. There was 1 patient of body movement and 1 patient of respiratory depression during the operation, and both patients completed the surgery successfully after treatment. All children had no serious surgery- and anesthesia-related complications. The anesthesia time was 40.5 (34.5, 47.5) min, the surgery time was 39.0 (33.0, 45.5) min, and the recovery time was 43.0 (28.0, 52.5) min Conclusion Interventional surgery for CHD guided by TTE at a mobile platform is a minimally invasive approach without radiation damage. Non-tracheal intubation general anesthesia with spontaneous breathing can be safely and effectively implemented in children who cannot cooperate.

Ankylosing spondylitis is a chronic immunoinflammatory disease that mainly affects the spine and the sacroiliac joint,the mechanism of which is closely related to signaling pathways,such as osteoprotegerin(OPG)/receptor activator of nuclear factor-κB(RANK)/RANK ligand,mitogen-activated protein kinase(MAPK),Wnt/β-catenin(β-catenin),phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR).Traditional Chinese medicine has the characteristics of multiple components and targets,and is widely used for the treatment of autoimmune diseases due to its low toxicity,strong specificity,and high efficacy.This review found that monomers and compounds of traditional Chinese medicine can exert anti ankylosing spondylitis effects by intervening in the aforementioned signaling pathways,regulating immune inflammatory responses,and inhibiting biological processes such as bone destruction,ectopic osteogenic differentiation,cell apoptosis,and autophagy.
