Objective To explore the clinical significance of the color Doppler ultrasound in diagnosis and treatment of artery injury of extremities. Methods Color Doppler ultrasound was used in 69 patients with limb trauma. Results Ultrasonography showed completely or partially vascular rupture in 13 cases (surgery confirmed 11 cases), artery injury and thrombosis in 18 cases (surgery confirmed 14 cases), highly suspicious vascular injuries in 19 cases (surgery confirmed 12 cases), vascular pressure, cramps or bone room fascia caused by high blood pressure obstacles in 19 cases (all confirmed afterclinical treatment). Conclusion Color Doppler ultrasound is the best approach for diagnosis and outcome evaluation of of artery injury of extremities.

Objective To assess the clinical value of high frequency ultrasound diagnosis for little bone fracture of ankle. Methods Thirty-seven ankle wound patients with negative X-ray examination underwent high frequency ultrasound. The second X-ray examination was performed on patients with hinted little bone fracture of ankle, and then CT/MR examination was performed on patients whose second X-ray examination was negative. The consequence of the second X-ray examination was counted and the sonographic features were analyzed. Results ①Little fracture of fibula (lateral malleolus) was in 16, of tibia (medial malleolus) in 12, of talus in 2, of scaphoid bone in 4, of metatarsale in 2 and of calcaneus in one patients. ②The second X-ray examination was positive in 26 patients (26/37, 70.27%), indicating that the detection rate of the second X-ray is higher than that of the first X-ray. ③Sonographic features of little bone fracture of ankle included incomplete bone surface of bone was rough and soft tissue swelling and thickening. No malposition of bone fracture was found. Conclusion High frequency ultrasound is supplementary for X-ray examination, being able to possess important clinical priority in the diagnosis of little bone fracture.

Objective To explore the value of high frequency ultrasonography for the early diagnosis of hyperuricemia in patients with joint disease.Methods Ninety-eight patients with hyperuricemia and 100 healthy persons,according to with or without history of acute gout attack,were divided into symptomatic group,asymptomatic group and control group,whose first metatarsophalangeal joint,ankle and knee were examined by high frequency ultrasonography.Chi-square test was used for statistical analysis.Results ① The joint lesions detection rate in the symptomatic group,asymptomatic group and the control group was 57％ (13/23),16％ (12/75),0 (0/100) respectively.There was statistical significant difference between the symptomatic group and the asymptomatic group (x2=9.69,P＜0.05).② The symptomatic group had 29 joint involvement (29/138),including 25 at the first metatarsophalangeal joint,3 at the ankle and one at the knee joint.The asymptomatic group had 14 joints involved (14/450),which were all located at the first metatarsophalangeal joint.③ The sonographic appearance of the two groups of arthropathy were synovial thickening,effusion,crystal deposition andbone erosion.The symptoms group presented as tophi,and increased synovial blood flow.Conclusion Patients with asymptomatic hyperuricemia may have joint diseases.The joint disease detection rate of the symptomatic group is higher than that of the asymptomatic group.High frequency ultrasonography can be used a conventional imaging method for the screening of patients with hyperuricemia joint disease.The focus of the screening of asymptomatic patients is the first metatarsophalangeal joint.The focus of the screening of symptomatic patients is the first metatarsophalangeal joint and the joints that were attacked in the past history.

Objeetive To investigate the changes of kidney cortex hemoperfusion before and after extracorporeal shock wave lithotripsy (ESWL) with contrast-enhanced ultrasonography (CEUS) and time-intensity curve.Methods Thirty patients of renal calculi were treated with ESWL and examined with CEUS before and after ESWL.Renal cortex blood perfusion parameters of the lithotriptic areas,including the contrast agent arrival time (AT) ,time to peak (TTP) .peak intensity (PI) and velocity parameters (β) were quantitatively measured with ACQ software.Results The value of AT,TTP and β were not significantly different before and after ESWL (P＞0.05) .PI value after ESWL was lower than that before ESWL (P＜0.05) . Conclusion CEUS can quantitatively evaluate the changes of kidney cortex hemoperfusion after ESWL,and reflect the minor renal damage resulted from ESWL.CEUS can be used as a new method of observing and evaluating the renal damage caused by ESWL.

Objective To assess the application value of color Doppler ultrasound (CDU) in the diagnosis of osteofascial copmarttnent syndrome (OCS) of forearm.Methods A total of 19 patients highly suspected of or diagnosed as acute OCS of forearm underwent CDU in comparison with clinical diagnosis and therapy.The echoes of muscles,the diameter and change of flow Doppler spectra of radial artery and ulnar artery were observed.Results In 16 patients of OCS,most of the forearm muscle swelled (enlarged more than 1/2-2/3 area) with the muscle echo enhanced unevenly:the textures were unclear or disappeared;and fluid or hematom appeared in muscles;and the diameter of radial artery and ulnar artery diminished.The flow Doppler spectra of radial artery and ulnar artery appeared as bid-diastolic whole inverse wave,bip-,unid-,uniph-wave,unip-,unid-uniph-wave and venous like Doppler wave.Resistance index increased.Conclusion The acute OCS of forearm has some sonographic characteristics.CDU can be used to diagnose the acute OCS of forearm.

Objective To investigate the damaging traits of cognitive function in first episode depression patients with the assessment of neuropsychological status ( RBANS) and Stroop Color-word Test. Methods Two hundred and thirty first-episode depression patients as experimental group and one hundred and seventy-eight health person as control were evaluated separately by repeatable battery for the RBANS and Stroop Color-word Test. Results In Stroop Color-word Test,the time required for completing the words,color,double-word,two-color in depression patients ( (14.37 ±6.65)s,(21. 58 ±8. 70) s,( 16. 56 ±8. 23)s, (37. 88 ± 13. 67) s) were longer than the control group ((12.38 ±3.34)s, (18.01 ±5.51) s, (14. 17 ±4. 37) s, (32. 87 ± 10.28) s). The difference between the two groups was found in cognitive function in first episode depression patients (P ＜ 0.05). The scores of color interference and meaning interference were no difference between the two groups (P＞0.05) . The patients'scores of the RBANS test in all items( (72.19 ± 17.22), (80.89 ± 15.29), (82.00 ± 16.37) , (98.74 ± 17.01) ,(82.09 ± 14.62) )were significantly poorer than those in healthy controls. Compared with control group, scores of the scales were significant difference between two groups. Pearson correlation analysis showed that RBANS total score and five factors had no correlation with HAMD total score and factors. It positively correlated with education level (P＜0.05) ,but not with sex (P＞0.05). Immediate memory,verbal function,delayed memory in five factors and RBANS total score negatively correlated with age and course of disease respectively, but breadth of vision,attention were not did(P＜0.05). Conclusion First-episode depression patients suffer from more serious and comprehensive damage of cognitive function such as memory,attention,executive function.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.
