Objective:To investigate the clinical value of a fully autonomous ultrasound robot in splenic ultrasound imaging.Methods:A retrospective study was conducted by enrolling 56 adult volunteers from the Third Medical Center of the Chinese PLA General Hospital between February 1-8，2024 as research subjects.A senior physician sequentially performed splenic ultrasound examinations using both the fully autonomous ultrasound robot and a matched portable ultrasound device. The acquired images were randomly coded and scored via a double-blind method by 3 physicians. The differences of the image quality scores and high-quality image proportions between the two groups were compared. Examination durations were recorded and compared between the two groups.Results:Both modalities successfully acquired splenic images in all 56 volunteers. No statistically significant differences were observed in image quality scores among the 3 physicians：（3.52 ± 1.31）points vs.（3.83 ± 1.23）points，（2.77 ± 1.23）points vs.（3.17 ± 1.17）points，and（3.48 ± 0.97）points vs.（3.79 ± 0.94）points（all P>0.05）. The numbers of images scoring ≥ 3 points showed no significant differences：45（80.36%） vs. 50（89.29%），30（53.57%） vs. 38（67.86%），and 48（85.71%） vs. 52（92.86%）（all P>0.05）. The fully autonomous ultrasound robot required significantly longer examination time［（60.86 ± 50.55）s vs.（7.95 ± 4.35）s， t=6.88， P＜0.01］. Conclusions:The fully autonomous ultrasound robot demonstrates comparable image quality and clinically acceptable image proportions to conventional portable ultrasound in splenic examinations. These findings suggest its potential equivalence to operator-dependent ultrasound for splenic imaging，supporting its feasibility as an alternative ultrasound modality despite longer procedural duration.

Objective:To explore the value of conventional ultrasonography combined with cervical compression in the diagnosis of orbital venous malformation (OVM).Methods:A total of 43 patients with suspected OVM were admitted in sequentially from January 2019 to July 2022 in the Third Medical Center of PLA General Hospital. All patients were examined by ultrasonography combined with cervical compression and demonstrated by operation or digital subtraction angiography (DSA). The conventional ultrasound features of OVM were summarized, and the value of conventional ultrasonography combined with cervical compression in the diagnosis of OVM was discussed.Results:The features of the conventional ultrasound combined with cervical compression for diagnosis of OVM were as follows: the interior of lesion was mainly tubular structure, and the compression test was positive. After cervical compression, the lesion enlarged and the inner diameter of the internal tubular structure widened. Doppler flow imaging showed that the interior of lesion was mainly venous blood flow. Compared with the results of postoperative pathology or DSA, the sensitivity, specificity, accuracy and positive predictive value of ultrasonography combined with cervical compression were 0.952, 1.000, 95.3% and 100%, respectively. The results of Fisher exact diagnosis showed that there was no significant difference between ultrasonography and operation or DSA of OVM( P>0.05). Conclusions:Conventional ultrasound combined with cervical compression can be used as an effective method for the diagnosis of OVM.

Objective:To explore the value of 5G robotic remote ultrasound in the diagnosis of plateau pulmonary edema(HAPE).Methods:A total of 27 patients who quickly entered Nagqu, Tibet at an altitude of 4 600 m-5 600 m from March to December 2021 and developed one of the clinical symptoms of HAPE were collected. All patients were examined by 5G remote robotic ultrasound and lung CT respectively. Kappa test was used to analyze the consistency of the two diagnostic results, and McNemar test was used to compare the difference in diagnostic results. The ROC curve was used to analyze the sensitivity and specificity of remote lung ultrasound scores in the diagnosis of HAPE.Results:Among the 27 patients, 16 showed thickening of pleural line, increasing of B line, lung consolidation, pleural effusion, etc. Meanwhile, 11 showed no abnormality. Additionally, 8 cases had diffuse pulmonary fluid in both lungs, and 8 cases had localized pulmonary fluid. ROC curve showed that the area under the curve of lung ultrasound score for the diagnosis of HAPE was 0.947 (95% CI=0.78-0.99, P<0.001). The sensitivity and specificity were 0.933 and 0.917, respectively. Lung CT diagnosis was positive in 15 cases. Lung CT showed thickening of lung texture, ground glass, small nodular shadow, fine reticulate shadow, etc. The diagnostic results of the two techniques were in good agreement (Kappa=0.924, P<0.001), and there was no significant difference between the two methods ( P>0.05). Conclusions:5G remote robotic ultrasound has high consistency with CT in the diagnosis of HAPE and is an alternative early diagnosis method for HAPE. It may have clinical application value in scattered medical resources and remote plateau areas.

Objective: To compare the therapeutic effects of two different moxibustion methods both with tai-yi moxa stick in treating primary dysmenorrhea. ＜br> Methods: Forty-three patients were randomized into two groups by the random number table according to their treatment orders. The causalgic group was intervened by causalgic stimulation with tai-yi moxa stick while the tepid group was treated by mild thermal stimulation with tai-yi moxa stick. Shiqizhui (EX-B 8) was selected for both groups. Visual analogue scale (VAS) was used for observation before and during the treatment by every 10 min to compare the clinical efficacies between the two groups. ＜br> Results: Before treatment, there was no statistically significant difference in pain intensity between the two groups (P>0.05). After treatment, both groups achieved significant improvements in pain intensity (P＜0.05), but the inter-group difference in pain intensity was still statistically insignificant (P>0.05), but the difference was enlarged comparing with that before treatment. The pain relief during the first 10 min of treatment was slower in the causalgic group than that in the tepid group. However, during the later 20 min, the pain relief in the calsalgia group gradually outpaced that in the tepid group. ＜br> Conclusion: The two moxibustion methods with tai-yi moxa stick both have a good instant analgesic effect in treating primary dysmenorrhea. For patients with primary dysmenorrhea, if 30 min is regarded as the treatment time, mild stimulation was suggested to be used for the first 10 min, and causalgic stimulation for the later 20 min to achieve a better curative effect.

Objective To assess the value and safety of SonoVue in ultrasonic diagnosis of abdominal diseases. Methods A total of 204 patients (149 male, 55 female) with abdominal examination of contrast-enhanced ultrasonography (CEUS) with SonoVue from August 2007 to February 2009 were reviewed. Results Definitive diagnosis were obtained 215 times in 204 patients (233 times) with abdominal CEUS. The diagnostic accuracy of CEUS was 92.27%, significant higher than that of conventional ultrasonography (62.23%). Anaphylactic shock happened 1 time (0.43%) in 1 patient. Conclusion CEUS with SonoVue can provide a high diagnostic accuracy with relatively safety of the possibility of serious adverse event.

Objective To evaluate the diagnostic advantages of contrast-enhanced ultrasonography in experimental abdominal blunt trauma in comparison of routine ultrasonogrphy. Methods Liver, spleen and kidney blunt trauma models were established in 10 canines and 12 rabbits. Both routine ultrasonography and contrast-enhanced ultrasonography were performed to identify the possible injury. Accuracy of the two ultrasonic technologies was compared in diagnosing each kind of organ and various injury degrees. Results Fifty-six trauma models including 22 livers, 14 spleens and 20 kidneys were established. There was significant difference between two ultrasonic methods in diagnosing liver, spleen and kidney injury (P<0.01);and contrast-enhanced ultrasonogarphy had particular advantage in detecting minor injuries of Ⅰ-Ⅱ scale (P<0.01). Conclusion Contrast-enhanced ultrasonography greatly enhances diagnostic accuracy of blunt abdominal solid organ trauma, especially in minor injuries.
