目的 分析经病理证实的颈部无痛性肿大淋巴结的声像图特点，比较良、恶性疾病中异常淋巴结的声像图特征，为临床医师的鉴别提供可靠的诊断依据。 方法 将2007年7月－2009年12月以颈部无痛性肿大淋巴结就医、并经病理证实的良、恶性疾病的97例患者作为研究对象，其中男56例，女41例；共检出淋巴结365个，依据病理诊断结果将研究对象分为良性组（98个）和恶性组（267个）。 结果 ① 大多数良性淋巴结：L/S＞2，形态接近椭圆形、门部回声规则无移位、皮质较薄、髓质形态规则，居中； 大多数恶性淋巴结短径相对增大，L/S≤2，形态趋于类圆形，包膜不完整，门部大多数偏离中心，皮质不均匀增厚，髓质变形移位或消失。② 良性淋巴结多表现为无血流型或门部规则血流型；恶性淋巴结多表现为周边血流或混合血流型。③ 大多数良性淋巴结血流阻力指数偏低，RI＜0.60；大多数恶性淋巴结血流阻力指数偏高，RI＞0.70。 结论 高频超声在颈部无痛性淋巴结肿大的良恶性鉴别中能够提供重要的诊断信息。
ObjectiveTo analyze the feasibility and effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound.MethodsThe clinical data of 30 patients with the fifth metacarpal neck fractures who were treated with elastic intramedullary nails fixation under the guidance of high frequency ultrasound and met the selection criteria between May 2013 and September 2017 were retrospectively analysed. There were 24 males and 6 females, the age ranged from 18 to 58 years, with an average of 31.4 years. The head-shaft angle of the fifth metacarpal was (55.6±11.3)°. The time from injury to operation was 12 hours to 8 days, with an average of 2.4 days. The operation time, number of intraoperative fluoroscopy, fracture reduction, complications, and fracture healing time were recorded. The head-shaft angle of the fifth metacarpal on the affected side after fracture healing were measured and compared with the healthy side. At last follow-up, the active range of motion of the fifth metacarpophalangeal joint of both sides were measured, and the function was evaluated by using the total active movement (TAM) evaluation standard of the Hand Surgery Association of Chinese Medical Association.ResultsThe operation time was 22-40 minutes, with an average of 32.4 minutes; the intraoperative fluoroscopy was performed once; ultrasound images and X-ray fluoroscopy showed that the fracture was well reduced and no adjustment was required. The incisions healed well after operation, without tendon adhesion or local numbness. All 30 patients were followed up 8-16 months, with an average of 11.7 months. The fracture healing time was 4-8 weeks, with an average of 5.6 weeks. The head-shaft angle of the fifth metacarpal was (13.2±1.4)°, which was significantly improved when compared with preoperative value (t=−20.02, P=0.00); and there was no significant difference (t=1.94, P=0.06) when compared with the healthy side [(12.6±1.0)°]. At last follow-up, the active range of motion of the fifth metacarpophalangeal joint on the affected side was (89.4±2.4)°, showing no significant difference (t=−1.58, P=0.13) when compared with the healthy side [(90.3±2.0)°]. According to the TAM evaluation standard of the Hand Surgery Association of Chinese Medical Association, all patients were considered to be excellent.ConclusionThe effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound is definite. It can dynamically observe the fracture reduction from different angles, reduce ionizing radiation and postoperative complications.

Methods From January 2006 to December 2009, 7 532 healthy women underwent breast sonography. The results of sonography in the individuals with different ages were statistically analyzed. Results Breast lesions were found in 2 861 cases (37.98%) and the other 4 671 were healthy. Among all of the individuals, 1 904 cases (25.28%) had cystic lesions, 944 (12.53%) had solid lesions and 13 (0.17%) had mixed lesions. There were 692 cases of accessory mammary tissue. Unilateral cystic nodules and solid nodules were more common than bilateral ones, whereas mixed nodules were usually sunilaterally. Cystic nodules were more common than solid nodules. Most common onset of breast lesions is in the individuals with the age of 20-30 and 31-40 years. Conclusion High-frequency sonography, as an examination for normal clinical breast screening provides more accurate diagnosis and early detection of breast lesions, which can provide scientific evidence for early detection, diagnosis and treatment for breast cancer.

Methods A total of 121 patients with B-PLG diagnosed by CDU combined with HFU between January 2008 and November 2011 were randomly selected. All of the patients underwent the surgery and had the record of surgical pathological examination results, which were compared with the results of the ultrasonography in order to evaluate the diagnostic accuracy of CDU combined with HFU for B-PLG. Results In 121 patients with B-PLG diagnosed by CDU combined with HFU before the surgery, cholesterol polyp was found in 62 (51.24%), infective polyp was found in 27 (22.31%), adenoma was found in 6 (4.96%), adenocarcinoma was found in 3 (2.48%), gallstones was found in 14 (11.57%), adenomyosis was found in 3 (2.48%), the wall structure gland disorder was found in 3 (2.48%), and submucosal soft nodules was found in 3 (2.48%) after the surgical pathological examination. Coincidence rate between CDU combined with HFU diagnosis and surgical pathological diagnosiswas 78.51% (95/121), and the misdiagnosis rate of CDU combined with HFU was 21.49% (26/121). Conclusion The accuracy of CDU combined with HFU diagnosing B-PLG is high, which can help to prevent precancerous lesion of gallbladder cancer.
Objective To explore the effect of self-designed early rehabilitation procedure of frozen shoulder incorporating high-frequency ultrasound technology in the outpatient treatment of patients with early frozen shoulder. Methods One hundred and eighty-two consecutive patients who attended the outpatient clinic of the Department of Rehabilitation Medicine of the First Affiliated Hospital of Xinjiang Medical University and were diagnosed with frozen shoulder between January 2018 and May 2021 were selected and randomly divided into the trial group and the control group, with 91 patients in each group. Patients in the trial group received early rehabilitation procedures for frozen shoulder, and patients in the control group received conventional physiotherapy. The Visual Analogue Scale (VAS) (including VAS score for resting pain and VAS score for active motion), active range of motion of the shoulder joint (external rotation, forward flexion, and abduction), Shoulder Pain and Dysfunction Index (SPADI) (including pain subscale score, dysfunction subscale score, and total score) were compared between the two groups before treatment (Week 0) and 4 and 8 weeks after the start of treatment (Week 4 and 8). Results A total of 143 patients (74 in the trial group and 69 in the control group) completed the study. There was no significant difference in any assessment index between the two groups in Week 0 (P>0.05). The results of the within-group comparison after treatment showed that the VAS score for resting pain (F=44.359, P<0.001), VAS score for active motion (F=158.458, P<0.001), anterior shoulder flexion (F=123.334, P<0.001), abduction mobility (F=117.539, P<0.001), total SPADI score (F=133.814, P<0.001), SPADI pain subscale score (F=74.093, P<0.001), and SPADI dysfunction subscale score (F=145.336, P<0.001) in Week 4 and 8 were better than those in Week 0, and the assessments in Week 8 were better than those in Week 4 in each group (P<0.05); in the control group, there was no statistically significant difference in the external rotation mobility of the shoulder in Week 4 compared with that in Week 0 (P=0.599), and the external rotation in Week 8 improved significantly compared with that in Week 0 (P<0.001), whereas the external rotation of the shoulder in Week 4 and 8 in the trial group improved significantly compared with that in Week 0 (P<0.001). The results of the between-group comparison after treatment showed that the two groups had statistically significant differences in resting shoulder pain VAS score (F=93.712, P<0.001), active motion VAS score (F=103.565, P<0.001), external shoulder rotation (F=13.388, P<0.001), anterior shoulder flexion (F=66.375, P<0.001), abduction mobility (F=110.253, P<0.001), total SPADI score (F=7.917, P=0.006), and SPADI pain subscale score (F=39.091, P<0.001); the SPADI dysfunction subscale score was lower in the trial group than that in the control group in Week 4 (P=0.002), but by Week 8 there was no statistically significant difference between the two groups (P=0.352). Conclusion The early rehabilitation program for frozen shoulder incorporating high-frequency ultrasound technology is more effective than conventional physiotherapy in the intervention of patients with early frozen shoulder, and may provide a referenceable example for the combined application of high-frequency ultrasound technology and physiotherapy.
