Objective To determine the value of contrast-enhanced ultrasound (CEUS) in the differentiation of primary liver cancer (PLC) and hepatic alveolar echinococcosis (HAE). Methods The data of 56 patients with PLC or HAE were collected between January 2010 and May 2015. Grayscale and CEUS features of the patients were analyzed retrospectively. The frequency of each imaging finding, including calcification, arterial enhancement, and internal enhancement were evaluated and compared. Results Statistically significant difference of the proportion of gender and age were detected between the two groups (P=0.013, 0.002). Thirty-eight PLC lesions were detected in 32 patients. The diameters of PLC lesions were 3-10 cm with an average of (5.6±2.1) cm. Thirty-two HAE lesions were found in 24 patients. The diameters of HAE lesions were 4-12 cm with an average of (9.1±4.4) cm. Statistically significant difference of lesion size and the incidence rate of calcification (5.3% vs. 75.0%) were seen between PLC and HAE (P<0.001). Peripheral enhancement were seen in 100.0% (38/38) PLC lesions, including 84.2% (32/38) hyperenhancement and 15.8% (6/38) dendritic hyperenhancement. All PLC lesions demonstrated hypoenhancement in late phase. Irregular peripherally hyperenhancement both in arterial and late phase were detected in 43.8% (14/32) HAE lesions. The other 56.2% (18/32) HAE lesions showed no peripheral enhancement both in arterial and late phase. No internal enhancement were seen in HAE lesions. The presence of arterial enhancement (100.0% vs. 43.8%) and absence of internal enhancement (0 vs. 100.0%) were significantly different between PLC and HAE (P<0.001). Conclusions PLC is predicted by arterial phase hyperenhancement and late phase hypoenhancement on CEUS. HAE is predicted with calcification on baseline sonography and internal non-enhancement on CEUS. Arterial phase enhancement is less common and less intensive in HAE than in PLC which also contributes to the differentiation of these lesions.
ObjectiveTo evaluate the clinical value of ultrasound-guided percutaneous co-axial technique in liver tumor biopsy.MethodsThe clinical data of patients who received ultrasound-guided percutaneous co-axial liver tumor biopsy from March 2015 to December 2016 in West China Hospital of Sichuan University were collected to retrospectively analyze the outcomes of biopsy success rate, sampling number, pathology diagnostic rate and incidence of complications.ResultsA total of 150 patients involving 99 males and 51 females were included, with a mean age of 54.9±4.5 years.

Objective To approach the enhancing patterns of hepatic focal nodular hyperplasia (FNH) under contrast-enhanced ultrasound, and improve the recognition on diagnosis for FNH by contrast-enhanced ultrasound. Methods The clinical data of 12 patients with histologically proved FNHs having accepted contrast-enhanced ultrasound examination from May 2007 to February 2009 in West China Hospital of Sichuan University were retroptectively analyzed, and related literatures were reviewed. Results All FNHs were rapidly enhanced in arterial phase and spoke-wheel-like sign was detected in 9/12 lesions. Slightly hyper-enhancement or iso-enhancement were showed in 11/12 lesions, while 1/12 lesions showed hypo-enhancement in late phase. Conclusion Contrast-enhanced ultrasound can display the dynamic blood perfusion of FNH, especially spoke-wheel-like arterial flow in early arterial phase, which is of great value for the diagnosis of FNH.
Portal hypertension (PHT) is a common complication of liver cirrhosis, which could be measured by the means of portal vein pressure (PVP). However, there is no report about an effective and reliable way to achieve noninvasive assessment of PVP so far. In this study, firstly, we collected ultrasound images and echo signals of different ultrasound contrast agent (UCA) concentrations and different pressure ranges in a low-pressure environment based on an in vitro simulation device. Then, the amplitudes of the subharmonics in the echo signal were obtained by ultrasound grayscale image construction and fast Fourier transform (FFT). Finally, we analyzed the relationship between subharmonic amplitude (SA) and bionic portal vein pressure (BPVP) through linear regression. As a result, in the pressure range of 7.5–45 mm Hg and 8–20 mm Hg, the linear correlation coefficients (LCC) between SA and BPVP were 0.927 and 0.913 respectively when the UCA concentration was 1∶3 000, and LCC were 0.737 and 0.568 respectively when the UCA concentration was 1∶6 000. Particularly, LCC was increased to 0.968 and 0.916 respectively while the SAs of two UCA concentrations were used as the features of BPVP. Therefore, the results show a good performance on the linear relationship between SA and BPVP, and the LCC will be improved by using SAs obtained at different UCA concentrations as the features of BPVP. The proposed method provides reliable experimental verification for noninvasive evaluation of PVP through SA in clinical practice, which could be a guidance for improving the accuracy of PVP assessment.
ObjectiveTo summarize our experience in the treatment of esophageal foreign bodies.MethodsA retrospective analysis of 149 patients of esophageal foreign bodies in the Second Affiliated Hospital of Air Force Military Medical University from December 2011 to May 2019 was carried out, including 75 (50.3%) females and 74 (49.7%) males with an average age of 57 (2-85) years.ResultsThere were 146 patients confirmed by endoscopy, and 3 patients were not found foreign body. Among the confirmed patients, 127 patients were removed by gastroscope and 19 patients were treated by operation. Esophageal foreign bodies are mainly related to the types of food. Jujube seed is the most common food foreign body in the northwest China. The injury rate of mucosal was 47.54% within 48 hours. The complication rate of taking out the foreign body after 48 hours was 100.0%. The success rate by endoscopy decreased (P=0.005), if the foreign body combined perforation. There was no statistical difference between the neck and other parts when using ultra-fine gastroscope (P=0.157).ConclusionThe sharper the foreign body is, the easier the perforation is. The earlier the foreign body is removed, the less complications are. The size of the foreign body determines the difficulty of endoscopic removal. Gastroscopy is the first choice for diagnosis and treatment, especially ultra-fine gastroscopy, and the foreign bodies that cannot be removed by endoscopy need surgical treatment.
Objective To systematically review the prevalence of depression in rural Chinese population aged 60 and above from 2010 to 2023. MethodsThe CNKI、WanFang Data、VIP、CBM、PubMed、Embase and Cochrane Library databases were electronically searched to collect cross-sectional studies on the prevalence of depression of elderly populations in rural China from January 2010 to March 2023. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using Stata 17.0 software. ResultsA total of 23 cross-sectional studies with a total sample of 34 916 cases and 11 308 depression patients were included. The meta-analysis results showed that the prevalence of depression in rural Chinese population was 31.02% (95%CI 26.10% to 36.16%). Subgroup analysis showed that the prevalence was higher among females than males; the GDS-30 scale had the highest detection rate, followed by the CES-D-10 and GDS-15 scales; the prevalence was higher in the Midwest than in the East; and the prevalence was higher in surveys conducted after 2015 than in 2015 and before. In addition, the prevalence of depression was higher in the rural elderly population aged 70 and above, non-married, illiterate or semi-literate, with poor self-rated health status, living alone, in poor economic status, with chronic diseases, and with low social activity. ConclusionThe prevalence of depression is high among the rural elderly population in China, and there are significant disparities in the prevalence of different characteristics of the elderly. These differences should be given more attention to improve the mental health of the rural elderly population. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo explore the safety and feasibility of contrast enhanced intraoperative ultrasonographyguided percutaneous radiofrequency ablation with artificial hydrothorax to hepatocellular carcinoma in the hepatic dome. MethodsThe clinical data of nine patients with hepatocellular carcinoma in the hepatic dome underwent ultrasonographyguided percutaneous radiofrequnecy ablation with artificial hydrothorax from January 2008 to June 2009 at Department of Hepatobiliopancreatic Surgery of West China Hospital were retrospectively analyzed. The perioperative results and recurrence of tumor were also analyzed. ResultsAll of nine patients with twelve tumors received successfully radiofrequency ablation with artificial hydrothorax of (2 444±464) ml (2 000-3 000 ml). The ablation time was 12-24 min (median 12 min), with an average of (15±5) min for each tumor. No hemothorax, pneumothorax, and death occurred during operation. One patient had ascites of 2 000 ml after ablation due to hypoalbuminenia, and ascites disappeared by infusion of abumin on 4 d after operation. The total volume of pleural drainage was 250-1 420 ml, with an average of (717±372) ml for each patient, and the drainage tube was withdrawn on 3-5 d after operation. The followup time was 7-23 months (mean 15 months). Tumor recurrence was found in three patients on 5, 6, and 7 months after operation, respectively. Of them, two patients were in stable disease stage after interventional and conservative therapy, respectively, and one case recurred at six months after operation and died of hypertensive heart disease and hepatic function deterioration at sixteen months after operation. The rest patients survived and no recurrence and metastasis was observed during the follow-up period.ConclusionThe technique of percutaneous radiofrequency ablation with artificial hydrothorax increases the feasibility of the minimal invasive treatment for hepatoma, which can be applied to hepatocellular carcinoma in the hepatic dome with high safety and clinical application value.
