Methods: Eighty patients admitted to our hospital from March 2023 to March 2024 were selected, all of whom were acute abdomen patients admitted to the Department of Obstetrics and Gynecology. In this study, the patients were divided into two groups. One group of 40 patients was given a simple abdominal B-ultrasound diagnosis (control group). The other group of 40 patients was given both abdominal and vaginal B-ultrasound examinations (experimental group). The diagnostic accuracy between the two groups was compared. Results: Patients in the experimental group had higher consistency rates with pathological diagnosis results in ectopic pregnancy rupture, embryonic arrest, acute pelvic inflammation, corpus luteum rupture, and intrauterine adhesions as compared to the control group. At the same time, the inspection accuracy rate of the experimental group (92.50%) was higher than that of the control group (70.00%) (P < 0.05). Conclusion: The combined application of abdominal and vaginal B-ultrasound in the diagnosis of acute abdomen was of great significance in improving the accuracy of clinical diagnosis and guiding doctors to provide effective treatment.展开更多

Methods: 20 pregnant women treated in our hospital in 2020 were selected. They were diagnosed by pathology to have different degrees of ectopic pregnancy. All pregnant women underwent transabdominal B-ultrasound and transvaginal B-ultrasound. The diagnostic accuracy of the two methods was compared. Results: in the diagnosis of ectopic pregnancy, there was a significant difference between the diagnostic accuracy of transabdominal B-ultrasound (80.00%) and transvaginal B-ultrasound (95.00%), which was statistically significant (P < 0.05). Conclusion: the application of transvaginal B-ultrasound in the diagnosis of ectopic pregnancy can significantly improve the diagnostic accuracy of ectopic pregnancy and provide a favorable treatment opportunity for the clinical treatment of this kind of pregnant women, which is worthy of further promotion in the diagnosis in the future.展开更多

PICC catheter insertion was performed using the Seldinger approach and was delivered from the basilic vein to the superior vena cava in a B-ultrasound guided manner. Moreover, the point raised during the PICC process would be treated immediately.Results： All of the PICCs were inserted successfully. The problems encountered are shown in the inserted central catheter（PICC） process, such as failures of venipuncture, the problem of inserting guide wire, the catheter was dif？cult to be delivered etc.Conclusions： The B-ultrasound guided approach enhanced the average success regarding the PICC insertion, particularly for the subset with a poor condition in the elbow super？cial vein. Due to the items that emerged in the PICC process, the effective prevention prior to surgery and treatment during the operation would be necessary.展开更多

The exact identification of the source and malignant degree of hNEN is important.However, there is a lack of information regarding diagnosis of hNEN with imaging. In addition, no studies have compared the imaging between hNEN and hepatocellular carcinoma(HCC) and among different sources and malignant degrees of hNEN.AIM To compare the ultrasound characteristics between hNEN and HCC and among different sources and malignant degrees of hNEN.METHODS A total of 55 patients with hNEN were recruited and defined as the hNEN group.Among them, 35 cases of hNET were defined as the hNET group. Twenty cases of hepatic neuroendocrine carcinoma(hNEC) were defined as the hNEC group.Among the 55 lesions, 29 were transferred from the pancreas, 20 were from the gastrointestinal tract, and six were from other sites. In total, 55 patients with HCC were recruited and defined as the HCC group. The characteristic differences of Bmode ultrasound and contrast-enhanced ultrasound(CEUS) between hNEN and HCC and among different sources and malignant degrees of hNEN were compared.RESULTS In the hNEN group, the proportions of multiple liver lesions, unclear borders,and high echo lesions were higher than those in the HCC group. The proportions of non-uniform echo and peripheral acoustic halo were lower than those in the HCC group(P < 0.05). The washout to iso-enhancement time and washout to hypo-enhancement time were lower than those in the HCC group(P < 0.05). The characteristics of B-ultrasound and CEUS among different sources of hNEN were similar, and the differences were not statistically significant(P > 0.05). B-mode ultrasound characteristics of hNET and hNEC were similar. The proportions of low enhancement at portal venous phase, non-uniform enhancement forms, and combined tumor vasculature in the hNEC group were larger than those in the hNEN group(P < 0.05).CONCLUSION Compared with HCC, hNEN showed multiple intrahepatic lesions, uniform high echo, uniform high enhancement at arterial phase, and rapid washout. Low enhancement at portal venous phase, overall non-uniform enhancement form,and the proportion of combined tumor vasculature in hNEC were larger than those in hNET.展开更多

Radiofrequency ablation (RFA) has become popular because of its advantages including little damage, therapeutic effect and reduced suffering. This report describes the effects and reliability of RFA in the treatment of 29 patients with hepatic cysts. METHODS: B-ultrasound-guided REA was used to treat hepatic mono-cyst or multi-cysts of 29 patients (63 tumors). Ablative efficiency and complications were assessed by imaging and clinical symptoms. RESULTS: The tumors were abated completely in 34 cysts with a diameter <5 cm and no recurrence was seen after 3 months. In 21 cysts with a diameter of 5-10 cm, tumor volume was decreased by over 70%, then reduction and fiberosis were found. In 8 cysts with a diameter greater than 10 cm, tumor volume was decreased by more than 60%, and in 2 cysts it was increased more slightly than that at I month after REA. In subsequent follow-up (6 and 12 months after REA), tumors <10 cm in diameter were fully ablated. No significant discomfort and complications were found in any patient. CONCLUSION: RFA for the treatment of hepatic cysts is safe, and free from complications.展开更多

Methods: The hepatic fibrosis model in rabbits with schistosomiasis was established. The experimental animals (24 rabbits) were randomly divided into four groups (group A, B, C and D, n =6). Group A (control group) was only treated by praziquantel; Group B was treated by mixture of Radix astragali and Salvia miltiorrhiza + praziquantel; Group C was treated by mixture of Radix astragali and Angelica sinensis + praziquantel; Group D was treated by mixture of Radix astragali, Salvia miltiorrhiza and Angelica sinensis + praziquantel. Then B-ultrasonogram was used to evaluate the effects. Results: Each group showed certain curative effect on liver fibrosis in rabbits with schistosomiasis. The efficacy of group B, C and D was better than group A, and that of group D was the best. The differences in long diameter, thickness diameter, transverse diameter and portal vein inner diameter of liver before and after treatment were statistically significant ( P <0.05). The liver function indexes and liver fibrosis indexes were significantly improved after treatment ( P <0.05). Conclusions: The mixture of Radix astragali, Salvia miltiorrhiza and Angelica sinensis combined with Western medicine treatment can obviously improve the efficacy on liver fibrosis of schistosomiasis.展开更多
