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.

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.
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）
【摘要】 目的 探讨纳米羟基磷灰石/聚酰胺66（nano-hydroxyapatite polyamide66，n-HA/PA66）颈椎融合器在颈椎间盘突出症前路手术重建中的临床疗效。 方法 2008年12月-2010年6月，对14例颈椎间盘突出症患者行前路椎间盘切除、椎管减压，以n-HA/PA66椎间融合器支撑植骨、钢板螺钉内固定治疗。随访时间3～12个月，平均6.3个月；随访时以日本矫形外科学会（Japan Orthopaedic Assoctiation， JOA）评分改善率评价患者神经功能恢复情况，复查X线片评估椎间融合器植骨融合情况，包括椎间高度及椎间融合器下沉情况。 结果 14例患者均成功完成颈椎前路减压手术以及椎间融合器的安放固定。所有患者术前症状均得到不同程度的改善，术后3、6、12个月的JOA改善率分别为87.0%、94.0%、97.0%。影像学检查显示所有患者植骨融合，椎间高度及椎间融合器的位置维持良好，无下沉、移位。 结论 n-HA/PA66颈椎间融合器具有早期支撑稳定功能，可有效维持颈椎椎间高度；术后植骨融合率高且便于X线片观察，是颈椎间盘突出症患者前路手术植骨的理想支撑材料，但长期效果需进一步随访观察。【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.
