Abstract
Background: To explore the application of contrast-enhanced ultrasound and color Doppler ultrasonography in the treatment of primary hepatocellular carcinoma (PHC) after Transhepatic Artery Chemoembolization (TACE). Materials and Methods: 49 patients with primary hepatocellular carcinoma were treated with TACE for 3-5 times. Before and after treatment, digital subtraction angiography, contrast-enhanced ultrasound and color Doppler ultrasound were performed. The lesions before and after contrast-enhanced ultrasonography and color Doppler ultrasonography were compared. The residual or recurrence and swelling of lesions before and after contrast-enhanced ultrasonography and color Doppler ultrasonography were analyzed. Detection of the capsule of the lesion. Results: The detection accuracy of contrast-enhanced ultrasound (95.77%) was significantly higher than that of color Doppler ultrasound (84.51%) (P<0.05). The detection rate of tumor envelope by contrast-enhanced ultrasound (22.54%) was significantly higher than that by color Doppler ultrasound (9.86%) (P < 0.05). The accuracy of detecting residual or recurrent lesions by contrast-enhanced ultrasound (91.67%) was significantly higher than that by color Doppler ultrasound (58.33%) (P<0.05). Conclusion: The rate of bone metabolism of perimenopausal women in Xuzhou is not optimistic. We need to pay close attention to the risk of bone metabolism disorder of perimenopausal women with older age, diabetes mellitus and osteoporosis, so as to provide useful help for improving the quality of life of perimenopausal women in Xuzhou.

Abstract
Background: This paper aimed to assess the clinical effects of abdominal aortic balloon occlusion (AABO) under color Doppler ultrasound guidance in treating pelvic tumors. Materials and Methods: Various databases, which contained China National Knowledge Infrastructure, Wanfang Data, Chinese Biomedical Literature Database, PubMed, Excerpta Medica Database (Embase), and Cochrane Library, were used for searching randomized controlled studies published from 2010 to present. The quality of the literature was assessed using the Newcastle-Ottawa Scale (NOS). Outcome measurements included intraoperative blood loss, transfusion volume, operative time, hospital stay, recurrence, and postoperative complications. Results: Six reference articles were obtained, including 223 patients who underwent AABO and 300 patients who did not. The NOS score was greater than 7 points in both groups. Meta-analysis showed that the intraoperative blood loss, transfusion volume, and surgery duration of patients undergoing pelvic tumor resection with AABO were all reduced (95% confidence interval (CI): -1504.53~-762.10, P<0.00001; 95% CI: -902.22~-575.45, P<0.00001; 95% CI: -80.20~-26.54, P<0.0001). No difference was discovered in the occurrence of postoperative complications, including nerve injury (95% CI: 0.30~1.34, P=0.23) and urethral injury (95% CI: 0.19~1.97, P=0.41) between both groups. The incidence of wound infection was relatively low (95% CI: 0.22~0.81, P=0.010). Additionally, no difference was discovered in hospital stay (95% CI: -6.85~0.79, P=0.12) and recurrence (95% CI: 0.45~1.53, P=0.12) between both groups (P>0.05). Conclusion: AABO under color Doppler ultrasound guidance can reduce intraoperative blood loss, transfusion volume, and operative time during pelvic tumor resection and can also reduce the incidence of some postoperative complications.

Abstract
Background: To investigate the role of pregnant-associatedplasma protein A (PAPP-A) and uterine artery Doppler ultrasound in predicting fetal growth restriction (FGR). Materials and Methods: In total, 120 pregnant women diagnosed with FGR in Shijiazhuang Obstetrics and Gynecology Hospital from January 2021 to December 2023 were selected as the FGR group, and 120 normal pregnant women were selected as the control group during the identical time frame. Maternal serum pregnancy-related protein A combined with uterine artery Doppler ultrasonography was performed during the period from the 11th, to the 13th+6 weeks of pregnancy. The course of pregnancy was observed in both groups of pregnant women. Results: The FGR group exhibited significantly reduced rates of vaginal delivery and fetal survival compared to the control group, while experiencing higher rates of preterm delivery and cesarean section, with statistical significance (P<0.001). The pulsatility index of the uterine artery (UtA-PI) and the resistance index of the uterine artery and the FGR group exhibited a higher proportion of early blood diastolic incisors compared to the normal group, with statistical significance noted at a level of P<0.001. The concentration of PAPP-A was lower than that of normal group (P<0.001). The sensitivity of combining UtA-PI and PAPP-A to predict FGR was 81.6%, and the sensitivity of combining UtA-PI and PAPP-A is 82.9%, which is 1.3% higher, but there was no statistically significant distinction between the two approaches (P>0.05). Conclusion: The implementation the combination between PAPP-A and Doppler ultrasound is an effective method to predict FGR.
