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.
【摘要】 目的 探討納米羥基磷灰石/聚酰胺66（nano-hydroxyapatite polyamide66，n-HA/PA66）頸椎融合器在頸椎間盤突出癥前路手術重建中的臨床療效。 方法 2008年12月-2010年6月，對14例頸椎間盤突出癥患者行前路椎間盤切除、椎管減壓，以n-HA/PA66椎間融合器支撐植骨、鋼板螺釘內固定治療。隨訪時間3～12個月，平均6.3個月；隨訪時以日本矯形外科學會（Japan Orthopaedic Assoctiation， JOA）評分改善率評價患者神經功能恢復情況，復查X線片評估椎間融合器植骨融合情況，包括椎間高度及椎間融合器下沉情況。 結果 14例患者均成功完成頸椎前路減壓手術以及椎間融合器的安放固定。所有患者術前癥狀均得到不同程度的改善，術后3、6、12個月的JOA改善率分別為87.0%、94.0%、97.0%。影像學檢查顯示所有患者植骨融合，椎間高度及椎間融合器的位置維持良好，無下沉、移位。 結論 n-HA/PA66頸椎間融合器具有早期支撐穩定功能，可有效維持頸椎椎間高度；術后植骨融合率高且便于X線片觀察，是頸椎間盤突出癥患者前路手術植骨的理想支撐材料，但長期效果需進一步隨訪觀察。【Abstract】 Objective To evaluate the clinical effect of artificial cervical vertebra fusion apparatus of n-HA/PA66 in anterior reconstruction of cervical intervertebral disc herniation. Methods From December 2008 to June 2010, 14 patients with cervical intervertebral disc herniation underwent anterior cervical discectomy,spinal canal decompression,spinal canal decompression and reconstruction by n-HA/PA66 composite artificial vertebral body combined with plate instrumentation. The patients were followed up for 3 to 12 months with an average of 6.3 months. Neurological function was evaluated by improvement rate of JOA score and situations of the supporting body was observed by X-ray in 3,6,and 12 months after the surgery.The intervertebral height,the 1ocations, and the fusion rate of the supporting body were assessed in order to evaluate the stability of the cervical spine and alignment improvements. Results All the patients had undergone the operation successfully.The preoperative symptoms improved to varying degrees.JOA improvement rate were 87.0%, 94.0%, and 97.0% 3,6,and 12 months after the operation,respectively.Imaging studies showed that in all cases graft fusion were achieved,and cervical alignments,intervertebral height,cervical spine stability and the locations of the artificial vertebral body were well maintained.No displacement and subsidence of the artificial vertebral body occurred. Conclusion n-HA/PA66 artificial vertebral body can provide early cervical spine support and stability and cervical intervertebral height.It has a high rate of graft fusion and is convenient to observe by X-ray.Therefore,n-HA/PA66 can be taken as an ideal graft for anterior degenerative cervical spine operation,but further follow-up study is still needed to evaluate the long-term effects.
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.

Methods From May 2009 to April 2010, 42 patients with vertebral body lesions underwent CT guided transpedicular biopsy. The clinical data including the puncture method, pahtological resutls, final diagnosis, and the pucture complications were retrospectively analyzed. Results The total accuracy rate of the puncture was 95.2%(40/42). The accuracy rate of the puncture was 94.3% (33/35) for malignant lesions and 100.0% (7/7) for benign lesions. No complication occurred. Conclusion CT guided transpedicular biopsy is very helpful in diagnosing vertebral body lesions with high accuracy and fewer complications.
