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.
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.
