Methods 100 normal adults’ chest posterior-anterior digital medical images in recent 10 days in our hospital were randomly chosen. Five specialists of our department were invited to see these images by soft-copy reading and the best WW/WL values of different parts of the chest they selected were recorded. All the data were analyzed in statistics and the best WW/WL was got. Results The best WW/WL values of soft tissues of chest wall were 2 083/4 840,ribs 2 667/4 908,lung fiber 2 067/4 960,hilum of lung 1 848/5 130,heart and large vessels 2 206/5 438,mediastinum and diaphragm 2 180/5 530,thoracic vertebrae 1 471/5 801,ribs that covered by heart and diaphragm1 428/5 975. Conclusion Different parts in chest poster -anterior digital medical images need special WW/WL in soft-copy reading for better diagnosis of images.

Mobile phase was acetonitrle-water (55∶45) and detection wavelength was 298 nm. The flow rate of mobile phase was 1 mL/min, and temperature was 30 ℃. Results The contents of MOA in Radix Ophiopogonis cropped in Sichuan and Zhejiang Provinces were 0.004 0%-0.009 6%, 0.006 7%-0.013 4%, and the contents of MOB were 0.002 1%-0.006 2%, 0.015 9%-0.028 2%, respectively. The contents of MOA in the extract of Radix Ophiopogonis cropped in Sichuan and Zhejiang Provinces were 0.007 5%-0.008 8%, 0.011 2%-0.012 6%, and the contents of MOB were 0.003 8%-0.005 1%, 0.020 7%-0.023 8%, respectively. Conclusion The contents of MOA and MOB in Radix Ophiopogonis cropped in Zhejiang Province and its extracts are more than those in Sichuan Province and its extrouts. The method can be used for the purpose of the quality control of Radix Ophiopogonis and its extracts.

Objective To determinate the toxic elements in Radix Astragali by ICP-MS. Methods The elements of Cu, As, Cd, Hg, Pb, Al, Cr, Sn, Ba in Radix Astragali were analyzed by ICP-MS. Results There were toxic elements in Radix Astragali. The concentration of Cu, As, Cd, Hg and Pb were not over the limits of Chinese Pharmacopoeia, but the concentration of Al, Cr and Ba were over the levels of other elements obviously. Conclusions There are difference of residues of the 9 kinds of toxic elements. It’s necessary to establish the determination methods of toxic elements (especially Al, Sn, Cr and Ba) in Chinese herbal medicines and the limits of the related toxic elements.

Objective To detected the motor cortex reorganization and compared the influence on reorganization process as regard to different transfer modes of contralateral seventh cervical nerve root (C7)in young rats model of total brachial plexus root avulsion. Methods The young Sprague-Dawley rats model of total brachial plexus root avulsion was established. The left radix dorsalis and radix ventralis from the fifth cervical nerve root (C5) to the first thoracic nerve root (T1)were exposed and the roots from C5 to T1 were avulsed from the spinal cord. Then, the contralateral C7 transfer operation was performed. Three different operative modes were applied randomly which included contralateral C7 transference to anterior division of the upper trunk (group A, n=30), to both musculocutaneous and median nerves (group B, n=30), or to median nerve (group C, n=30). The movement evocation of motor cortex was measured by intracortical microstimula-tion in both hemispheres, and functional reorganization was assessed dynamically in 1.5, 3, 6, 9 and 12 months after operation. Results After contralateral C7 transference, the ipsilateral motor cortex initially acti- vated the injured limb at 1.5 month, and subsequently the motor cortex of both hemispheres activated the in-jured limb at the 3rd and 6th month. The injured limb was activated mainly by the contralateral motor cortex in group A at the 9th month. The contralateral motor cortex exclusively controlled the injured limb in all three groups at the 12th month after the operation. Meanwhile, the extent of functional reorganization was better in group B than that of group C. Conclusion After contralateral C7 transfer operation, motor cortex in charging injured limb developed a transhemispheric functional reorganization in young rats with total brachial plexus root avulsion. Different operative modes contributed to the functional reorganization of motor cortex. Transferring contralateral C7 to anterior division of the upper trunk or to both musculocutaneous and median nerves provided better functional reorganization than to median nerve.

Objective To explore the impact of systematic retroperitoneal lymphadenectomy (SL) in patients with advanced ovarian cancer. Methods The data on 188 patients with FIGO stageⅢC epithelial ovarian cancer were retrospectively analyzed. All the patients underwent primary debulking surgery and then received platinum-based chemotherapy. The patients were divided into SL group and non-systematic lymphadenectomy (USL) group. Progression free survival (PFS) and overall survival (OS) times were analyzed. Results PFS and OS were higher in SL group than in USL group (36 versus 17 months and P = 0.022; 58 versus 52 months and P = 0.041). Univariate analysis showed that both SL and optimal debulking surgery were the independent prognostic factors , but multivariate analysis indicated that optimal debulking surgery was the only independent prognostic factor. However , for 143 patients without enlarged retroperitoneal lymph nodes , multivariate analysis showed that either SL or optimal debulking surgery were the independent prognostic factor (P = 0.040 and P = 0.014). Conclusions Optimal debulking surgery is helpful in improvement of the survival in patients with advanced ovarian cancer. For patients without enlarged retroperitoneal lymph nodes, SL still has a positive effect on the prognosis.

Objective To investigate the characteristic of surgical treatment of burns in pediatrics patients. Methods From January 2006 to March 2012,47 pediatrics patients and 244 adult patients were received the surgical treatment in our hospital. The clinical data of two groups were analyzed retrospectively and compared. Results The female ratio in pediatric patients was higher than adult group,and almost patients received operation,especially plastic surgery and skin repair,with less surgeries of wound repair and infected surgeries. The preopera-tive physiological index between two groups was no significantly different. Conclusion On the premise of effective preoperative preparation, we could carry out surgical treatment of burns for pediatrics patients positively.
