Prediction of risk factors of occurrence and development of degenerative lumbar spondylolisthesis with sagittal parameters of the spine and pelvis / 临床外科杂志

Objective To explore the risk factors related to the development and progression of lumbar degenerative spondylolisthesis (LDS).Methods A total of 71 patients with LDS or degenerative spinal stenosis (DSS) were retrospectively.Thirty-six patients with LDS (group LDS) and 35 patients with DSS (group DSS) were enrolled.Spinopelvic parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), regional lumbopelvic lordosis angles (PR-LI, PR-L2, PR-L3, PR-L4, PR-L5), pelvic morphology (PR-S1), lumbar 4 slope (L4 S) and lumbar 5 slope (L5 S) were assessed on whole spine lateral radiographs in a standing position.All the parameters from LDS will compared with those of DSS and normal population respectively, Student's t-test was used to compare each parameter among the LDS, DSS and normal population.Results PI [ (57.67±11.78) °], SS [ (37.83±9.17) °] and LL [ (54.65±11.45) °] in group LDS were significantly greater than those of group DSS [ (44.47±8.75) °, (28.18±9.02) °, (38.97±15.59) °] and normal reference value [ (44.75±9.01) °, (33.57±7.64) °, (48.75±10.03) °] (P＜0.05).L4 S [ (8.18±9.98) °] and L5 S [ (19.96±8.33) °] in group LDS were greater than the group DSS[ (3.32±7.95) °, (10.87±8.02) °] (P＜0.05).The PR-L4 [ (57.63±13.44) °], PR-L5 [ (45.76±10.92) °] and PR-S1 [ (27.91±10.41) °] in group LDS were significantly smaller than those of group DSS [ (65.48±10.70) °, (56.33±9.15) °, (38.63±7.29) °] (P＜0.05).Conclusion Greater PI may lead to the development and progression of lumbar degenerative spondylolisthesis.L5 S is a parameter that can be used to predict the risk of LDS.The lower regional lumbopelvic lordosis angles in LDS were smaller than those of DSS.

Investigation and collection development pattern for genuineness of Aconitum carmichali / 中国中药杂志

<p><b>OBJECTIVE</b>To study the collection the development pattern for genuineness of Aconitum carmichalii, which lays a good basis for the sustainable utilization of A. carmichalii resources.</p><p><b>METHOD</b>We adopted the combined methods of investigation of herbal literatures, researching of origins in A. carmichalii and consultation with the experts, identified the development pattern of A. carmichalii. From genuine producing areas and its genuineness.</p><p><b>RESULT</b>The genuine producing area of A. carmichali is Jiangyou district of Sichuan province, genuine medicinal materials of A. carmichalii is mainly oriented by production techniques. It has cultivation techniques, unique and exquisite processing, which have trim root delicately and remove top complexly.</p><p><b>CONCLUSION</b>A. carmichalii from Jiangyou is famous genuine medicinal materials in Sichuan Province.

CT-guided percutaneous lung biopsy diagnosis of diffuse lung diseases / 中国医学影像技术

Objective To assess the diagnostic value of the CT-guided percutaneous lung biopsy in diffuse lung diseases. Methods CT-guided percutaneous lung biopsy was performed using 18G or 20G biopsy needle in 68 patients with diffuse lung diseases. The main imaging changes of these patients included network of diffuse nodular or nodular, diffuse reticular lines shadow and diffuse ground-glass density in the lungs. Results Punctures were successful in all 68 patients, and the diseases were clearly diagnosed, including 19 patients with malignant (9 bronchioloalveolar carcinoma and 10 metastatic carcinoma) and 49 with benign (27 disseminated pulmonary tuberculosis, 8 sarcoidosis, 7 silicosis and coal worker's lung, 2 interstitial pneumonia, 4 pulmonary alveolar proteinosis allergic and 1 pneumonia) lesions. The major complications of puncture were pneumothorax and bleeding, and the incident rate of complications was 17.65%. Conclusion CT-guided percutaneous lung biopsy is a useful, safe technique with low complications, high accuracy rate for the diagnosis of diffuse lung diseases.
