BACKGROUND: Facial tie-over is a conventional method for skin graft fixation, but it needs further improvements due to the unsatisfactory fixation, survival quality, postoperational contraction and appearance. OBJECTIVE: To improve the survival quality of facial skin grafts using the modified wire frame tie-over for the fixation. DESIGN, TIME AND SETTING: An observation trial was carried out at the Department of Burns in Beijing Jishuitan Hospital from January 2003 to December 2007. PARTICIPANTS AND MATERIALS: A total of 23 patients suffered from facial burns and post-burn scar were enrolled from the Department of Burns in Beijing Jishuitan Hospital, 16 males and 7 females, with a mean age of (37?18) years. The wire frame tie-over skin grafts were used in 32 facial wounds, including 8 cheek wounds, 20 eyelid wounds and 4 perioral wounds. The 1.0-1.5 Kirschner wire frame, made of stainless steel, was shaped as the wound outline; the rubber bands and clip were sterilized with ethylene oxide. METHODS: All the patients were grafted by means of wire frame tie-over, and the maximal area of skin graft was 18 cm?10 cm. After the routine skin grafting, the Kirschner wire frame was sutured to the edge of wound, then tie-over was performed using the sutures or the sterilized rubber bands fixed on the wire frame. The wire frame was removed three to four weeks after operation. MAIN OUTCOME MEASURES: The survival of skin grafts was recorded at the removal of tie-over, including survival rate of skin grafts and appearance of crater phenomenon that was prominent at edges and depressed in center; The skin grafts were pictured to observe the early contraction at the removal of wire frames 3-4 weeks later. The patients who were potential for the long-term follow-ups were used to observe the long-term contraction. RESULTS: Among 32 wounds in 23 patients, 31 skin grafts had an excellent skin grafting, except a partial graft necrosis occurred in one case due to insufficient debridement. The skin grafts were flat and intact, no crater phenomenon was found. Three or four weeks after operation, the area of skin grafts maintained in original style, no early contraction was found. One year later, the patients appeared mild contraction of skin graft, and the skin appearance was satisfactory. CONCLUSION: Improved wire frame tie-over method can increase the survival quality of facial grafts and alleviate the graft contraction.

Objective To investigate the changes of brain volumes in neuromyelitis optica (NMO)patients using voxel-based morphometry (VBM) method, and preliminarily explore the pattern of cerebral anatomical impairment. Methods Twenty-three clinically defined NMO patients and 15 gender and age matched healthy volunteers underwent 3-dimensional (3D) fast spoiled gradient echo (FSPGR) sequence scanning on 3.0 Tesla MR systen. Raw data was processed and analyzed using statistical parametric mapping (SPM) 5. Whole brain volumes included grey matter volume (GMV), white matter volume (WMV), total intracranial volume (TIV), grey matter fraction (GMF), white matter fraction (WMF),brain tissue fraction (BTF) and regional brain volumes between the two groups were compared by independent samples t-test and an Pearson were performed to compare the regional brain volumes and the ages. Results GMV of NMO group[(610. 2 ± 55.0) ml] was significantly decreased comparing to healthy control group[(657. 2 ± 36. 3) ml] (t = - 2. 915, P ＜ 0. 05). The age of NMO patients [(40 ± 9) years old] showed negative correlation with GMF [(42. 5 ± 2. 6) %] (r = - 0. 673, P ＜ 0. 05). Regional brain volume analysis showed decreased GMV in left insula and bilateral posterior cingutates in NMO patients,while decreased WMV was found in left frontal and left parietal white matter. Conclusion VBM could detect brain volume changes sensitively. Total grey matter volume in NMO patients was decreased comparing to HC group. Regional grey matter atrophy in NMO patients occurred in left insular and bilateral posterior cingutates, regional white matter atrophy occurred in left frontal and left parietal lobe.

Homeopathy is a relatively independent therapeutic system that is very popular in Europe and the United States. Although homeopathic medicine and Chinese medicine belongs to two different medical systems stemmed from two distinct cultural backgrounds, they do share similar philosophies, holistic treatment principles, and more importantly diagnostic approaches. This study focuses on homeopathic diagnosis and discusses its diagnostic strategies, laws and clinic practice characteristics through the comparison of homeopathic and Chinese medicine diagnosis.

OBJECTIVE To investigate the clinical distribution and resistance of Acinetobacter baumannii.METHODS The bacteria were identified by BioMerieux VITEK32.Susceptibility was tested by Kirby-Bauer method.RESULTS Among specimens from which A.baumannii was examined,sputum accounted for 78.64%,secretion(9.62%)and urine(6.81%).A.baumannii was mainly distributed at ICU ward(29.58%)and then was respiratory ward(21.36%).The resistance of A.baumannii was serious.The antibiotic drugs which had the low resistance were ?-lactam/?-lactamase inhibitor combinations such as sulperazone(22.14%)and carbapenems such as meropenem(32.95%),imipenem(33.04%),and so on.CONCLUSIONS The infecton of multi-drug resistant A.baumannii has increasing tendency.Therefore monitoring A.baumannii constantly and regularly,finding out resistant strains timely and adjusting the treatment methods are very important for the prevention of nosocomial infection.

OBJECTIVE:To observe the effect of different concentration of borneol nasal drops on the vasopermeability of nasal mucosa and the cerebral vessels.METHODS:Guinea pigs were divided into5groups,i.e.borneol group in3different concentrations(0.5%,1.0%and2.0%),histamine group and liquid paraffin group.Guinea pigs were injected i.v with2%evans blue(EB)after administration with nasal drops,which were then put to death10min later;the nasal mucosa and brain tissue of which were obtained and the EB contents in which were determined.RESULTS:Compared with the liquid paraffin group,the EB contents in the nasal mucosa and brain tissue in the borneol groups were higher(P
