Objective Vibration response imaging(VRI) is a new lung sound imaging technology.It provides quantitative lung data（QLD） of vibration in respiratory system.The study is to explore the value of QLD in diagnosis of obstructive lung diseases.Methods The QLD of 61 chronic obstructive pulmonary disease（COPD） patients，58 asthma patients and 64 healthy volunteers were reviewed.The QLD were transferred to abnormity and variation by a formulation and were analyzed.Results The mean QLD of healthy volunteers were 8.4，14.5，22.0，11.1，18.5，25.5 with mean abnormity as 10.0 and mean variation as 2.0.The mean QLD of the COPD patients were 11.6，16.7，21.9，12.6，17.2，20.1 with mean abnormity as 47.1 and mean variation as 10.9.The mean QLD of the asthma patients were 12.8，17.2，19.9，13.3，17.5，19.3 with mean abnormity as 58.1 and mean variation as 12.2.The abnormity and variation of the patients were different from those of volunteers（Plt;0.05）.When abnormity≥20.0 or variation≥5.0 was define as threshold value，the specificity was 87.5%.The diagnosis sensitivity for COPD is 82.0% and sensitivity for asthma is 82.8%.Conclusion COPD and asthma patients can be detected by quantitative lung data from vibration response imaging.
ObjectiveTo investigate the effect of jejunostomy combined with Ivor-Lewis or McKeown operation on the treatment of middle and lower esophageal cancer.MethodsThe clinical data of 127 patients with middle and lower esophageal cancer admitted to our hospital from June 2018 to October 2019 were retrospectively analyzed, including 89 males and 38 females, aged 62.82±8.65 years. The patients were divided into an Ivor-Lewis group (IL group, 72 patients) and a McKeown group (MK group, 55 patients) according to surgical methods. Patients in the IL group received jejunostomy combined with Ivor-Lewis operation, and patients in the MK group received jejunostomy combined with McKeown operation. The operation time, postoperative bedside electrical impedance tomography (EIT) parameters, postoperative inflammatory factor levels, postoperative complications and rehabilitation of the two groups were compared.ResultsThe operation time (262.65±49.78 min vs. 303.04±60.13 min), postoperative eating time (10.54±2.22 d vs. 11.47±2.49 d) and postoperative hospital stay (14.78±2.47 d vs.15.72±2.36 d) in the IL group were significantly shorter than those in the MK group (P<0.05). The blood loss (156.13±52.43 mL vs. 158.87±48.47 mL) and the number of lymph node dissection (29.47±8.88 vs. 30.17±9.80) in the IL group were less than those in the MK group, but the differences were not statistically significant (P>0.05). The repeated measurement analysis of variance showed that the time point could significantly affect tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-8 levels (Ftime point=520.543, 272.379, 147.688, all P<0.05), but the surgical methods and the interactive effect of time point and surgical methods did not affect the levels of TNF-α, IL-6 and IL-8 (P>0.05). Postoperative bedside EIT image parameters were statistically different on the postoperative 1 d, 3 d, 5 d and 7 d between the two groups (P<0.05). Compared with the MK group, the incidences of recurrent laryngeal nerve injury, arrhythmia, pulmonary infection and atelectasis, anastomotic leakage, gastric wall necrosis and stump fistula, secondary thoracotomy and abdominal hemostasis, and intestinal obstruction were lower, but the differences were not statistically different (P>0.05). The recurrence rate of patients in the IL group within 6 months was lower than that in the MK group, but the difference was not statistically significant (8.33% vs. 9.09%, P>0.05).ConclusionJejunostomy combined with Ivor-Lewis or McKeown surgery have equivalent effects on patients with middle and lower esophageal cancer.
目的：探討3D網塞在腹股溝疝修補術中的應用。方法：隨機選取30例腹股溝疝患者用3D網塞行無張力疝修補術。結果：本組平均手術時間35 min，平均術中出血15 mL。術后8~24 h下地活動，均未給鎮痛藥，無手術死亡、無切口感染、陰囊血腫等并發癥，患者局部舒適性好，異物感不明顯，隨訪5~10個月，無一例復發。結論：使用3D網塞作為充填式疝修補材料具有手術創傷小、恢復快，患者局部舒適性好，復發率低等優點。
PURPOSE:To evaluate the B sean ultrasonic examination in diagnosis and prognosis of infectious endophthalmitis in children. METHODS:The hospital records of 44 children with infectious endophthalmitis were retrospectively analysed. The correlation between the initial B scan eehographic findings and the initial vision and the vision at discharge were analysed by t-test. RESULTS :The average visual, acuity was hand moving on admission,and 0.04 at discharge. Both the final vision and the initial vision were associated with the severity of vitreous opacity. The ultrasonic findings including retinal detachment and choroidal detachment were associated with poor vision outcomes. CONCLUSION :The ocular B scan ultrasonic examination was effective to predict the final vision in infectious endophthalmitis in children. （Chin J Ocul Fundus Dis,1997,13: 134-135）
Objective To discuss the clinical effect of cross-finger flap with cutaneous branch of the ulnar digital finger on repairing the palmar soft tissue defect of the finger. Methods From October 1996 to June 2004, crossfinger flaps were used to repair the palmar soft tissue defect of the finger in 25 cases( 32 fingers ) with tendon or bone exposed. There were 18 males and 7 females, and theirages ranged from 13 to 45 years. Among them, 6 cases were incised injury, 8 cases were impact and press injury, 11 cases were crush injury; and 2 cases were thumb, 8 cases were index, 5 cases were middle finger, 3 cases were ring finger, 2 cases were little finger, 2 cases were index and middle finger, 2 cases were middle and ring finger, and 1 cases were index, middle, ring and little finger. Thetime from injury to diagnosis was 30 min to 48 h, and the size of the tissue defect was 1.5 cm×1.0 cm to 4.1 cm×2.0 cm. All cases were treated with emergent operation, and the sense of the flap was recovered by anastomosing the cutaneous branch of the ulnar digital finger and the distal digital nerve of injured finger. The flap pedicle was dissected 3 weeks later. Results Followup was conducted for 6 to 26 months and it showed that the cross-finger flaps all survived with full digital fingertip, satisfactory appearance, good function, and normal sense. The discrimination of two points was 5-8 mm. Conclusion As it is easy to operate and with satisfactory appearance and good function restoration, cross-finger flap with cutaneous branch of the ulnar digital finger is effective in repairing the palmar soft tissue defect of the finger.
