Objective To analyze 137 cases of clinical invasive fungal infection (IFI), and to sum up clinical experiences in the treatment of early anti-fungal. Methods 137 patients with 91 males and 46 females, who suffered from invasive fungal infection in ICU from January 1, 2000 to June 30, 2006, were enrolled in this study. The age ranged from 17 to 82 years. Among 137 patients with IFI, the respective incidence of infection of Candida albicans, Candida glabirate, Candida tropicalis and Candida parapsilosis was 47.4%, 26.3%, 20.4% and 3.6%. The sputum, urine, blood and other excreta were collected for examination three days after admission and then every three days. Results Out of the 137 patients, 42 patients were complicated with hemorrhage (30.7%), 53 patients developed candida rash in the chest, abdomen and extremity (38.7%), and 49 patients developed organ dysfunction (35.8%). The chest films revealed that infiltration caused by IFI mainly occurred in the apex of lung in some patients. 137 patients were treated with fluconazole at first, and among them, 64 patients were cured. The cure rate was 46.7%. 39 patients out of 61 patients treated with Amphotericin B(AmB) or lipid AmB were cured. The cure rate was 63.9%. 11 patients were treated with voriconazole and 6 patients were cured. The cure rate was 54.5%. 28 patients failed to respond to the above therapy and died.The mortality was 20.4%. Conclusion The clinical symptons of IFI included hemorrhage, candida rash, organ dysfunction, and infiltration in apex of lung. Fluconazole and amphotericin B(AmB) or lipid AmB still have a good curative effect on invasive fungal infection.

OBJECTIVE An understanding of the complex anatomy of the anterior skull base is crucial for the surgeon doing endoscopic surgery. The anatomic data of the olfactory sulcus and adjacent structures in Chinese patients were defined using 3-dimensional reconstruction images. The surgeon is encouraged to develop a detailed pre-operative surgical plan by utilizing these dynamic anatomical observations to avoid intracranial injury. METHODS The paranasal sinus CT scanning images of 100 adults were reconstructed for observation using EBW2.0 software and multiplanar reformation. All data obtained were in the coronal plane from the anterior point of the olfactory sulcus. The cribriform plate depth as compared to the ethmoid roof and adjacent structures, was measured bilaterally. Data obtained on adjacent structures include the vertical height of the lateral lamella of olfactory sulcus, the horizontal distance between the cribriform plate and the orbital lamella, the length of the middle turbinate, the height of the orbit, and the vertical distance between the cribriform plate and the nasal floor. RESULTS The olfactory sulcus was classified into three types: platform type (60 %), sloping type (17 %) and mixed type(23 %), as distinguished from Keros classification. In this study the vertical height of the lateral lamella of olfactory sulcus was (5.03 ± 0.17) mm (R) and (5.39 ± 0.19) mm (L) in platform type, and (2.79 ± 0.49) mm (R) and (4.72 ± 0.49) mm (L) in the mixed type. There were statistically significant differences between the right side and the left side in these two types (P＜0.01). The horizontal distance between the cribriform plate and the orbital lamella on the same side was significantly different between the platform type and the mixed type of olfactory sulcus. A similar result was observed for the vertical distance between the cribriform plate and the nasal floor. Gender differences exist in the horizontal distance between the cribriform plate and orbital lamella on the same side and the vertical distance between the cribriform plate and the nasal floor. CONCLUSION Different types of olfactory sulcus have distinct characteristics, hence care which must be taken into account when doing endoscopic surgery.

Objective To investigate the effects of rhubarb on the expression of glucocorticoids receptor (GR)and peripheral blood lymphocytes in burning-induced septic rats. Methods Sixty-six male healthy Sprague-Dawley(SD)rats were randomly divided into sham operated control group(n=18),sepsis model group(n=24) and rhubarb treatment group(n=24),each group was further randomly divided into 12,24 and 72 hours subgroups according to different time points. The model of scald sepsis was replicated by scald injury induced by boiling water at the rat back accounting for 30% total body surface area(Ⅲ grade of scald),and administration of endotoxin (5 mg/kg)into the peritoneal cavity 12 hours after scald injury. After the successful establishment of septic models, the rats in the rhubarb treatment group were immediately infused with 50 mg/kg rhubarb powder dissolved in 1 mL saline through a gastric tube,while the rats in sham operated control group and sepsis model group received saline by the same way as a substitute for rhubarb. The the binding capacity of GR of peripheral blood leucocyte and binding activity of GR of hepatocyte were analyzed by radiation ligands binding assay. The CD4+,CD8+as well as CD4+/CD8+ ratio in peripheral blood lymphocytes were detected by flow cytometer. Results The binding capacity of GR of peripheral blood leucocyte and binding activity of GR of hepatocyte were significantly decreased in a time-dependent manner in sepsis model group compared to those of the sham operated control group,while in the rhubarb treatment group they were increased in a time-dependent manner after interference of rhubarb, and they were higher than those in the model group at the same time points〔leukocyte GR binding capacity (locus/cell)at 12,24,72 hours :1 515.38±300.44,1 859.63±258.26,1 890.50±307.88 vs. 1 122.63±225.39, 1 008.88±150.41,724.38±91.19;hepatocyte GR binding capacity(fmol/mg):210.19±26.26,258.01±20.98, 283.38±38.21 vs. 153.11±30.07, 129.83±26.89, 94.08±14.30, all P<0.01〕. Compared with the sham operated control group,the CD4+ and CD8+ were decreased in various degrees at 12 hours and 24 hours in the septic group, at 24 hours the differences being statistically significant (P<0.01 and P<0.05). CD4+/CD8+ratios were decreased significantly at all time points,the differences were statistically significant at 24 hours and 72 hours(both P<0.01). The CD4+ T cell and CD4+/CD8+ ratio at all the time points were increased at various degrees in the rhubarb treatment group,and the differences from those in the sepsis model group at 24 hours and 72 hours were statistically significant (1.58±0.69, 1.56±0.49 vs. 1.02±0.41, 1.01±1.68, both P<0.01). Conclusion Rhubarb can modulate the binding capacity of GR of peripheral blood leucocyte and the binding activity of GR of hepatocyte,and via its influence on the number of peripheral leucocytes,the immune dysfunction in the sepsis processes is improved.

BACKGROUND:Autologous bone-skin flap transplantation is the best method for the repair of composite tissue defect, but the repair ability is limited, with big trauma, new tissue defect and a certain dysfunction. Al ogeneic bone has the osteoinductive capacity, which can be used to prepare the bone-skin flap. OBJECTIVE:To research the pathological change of the al ogenic bone during the prefabrication of bone-skin flap with al ogeneic bone implant. METHODS:The experimental animals were Bama miniature pigs. Deep-frozen al ogenic bone was implanted in iliac artery-supported tissue flap compartment of miniature pigs. After operation, the local reactions were observed, the al ogenic bone were studied by general observation and histological analysis at 4, 8, 12 and 16 weeks after implantation respectively. RESULTS AND CONCLUSION:Obvious inflammation reaction was not observed in the surgical zone. The al ogeneic bone was vascularized at 4 weeks after implanted into the flap tissue without obvious osteoblast-like cells. The vascularization, bone resorption and uneven distributed osteoblast-like cells and osteoclast-like cells were observed at 8 weeks after implantation, and new bone formation was observed. At 12 weeks after implantation, new bone formation and bone absorption was strengthened, and the morphology of the bone graft was changed. At 16 weeks after implantation, al ogenic bone turned into fragments and absorbed, and no new bone formation was observed. The results indicated that during the prefabrication of bone-skin flap with al ogeneic bone implantation, the pathological changes of the al ogeneic bone was observed with time prolonging, and the bone-skin flap should be transplanted in time.

ObjectiveTo study the effects of small-dose glucocorticoid (GC) on glucocorticoid receptor (GR) and cellular immune function in critical patients.MethodsForty ICU critical patients admitted in Shanghai Changzheng Hospital from March 2007 to March 2009 were enrolled in the study and were divided into GC group and non-GC group according to the use or absence of GC.Blood samples were collected at days 1,7 and 10 after GC treatment to detect GR binding affinity of mononuclear leukocytes (MNLs) and polymorphonuclear leukocytes (PMLs) in the peripheral blood and the CD4/CD8 ratio in the T lymphocytes.The method of GC use was that the hydrocortisone was given intravenously at a dose of 100 mg every eight hours.ResultsGR binding capacity of MNLs at day 1 and 7 showed no statistical difference between the GC and non-GC groups.GR binding capacity of MNLs in the GC group was lower at day 1 and was much lower at day 7 (P ＜ 0.05 ).However,in the non-GC group,it was lower at day 1,but showed significant improvement at day 7 ( P ＜ 0.05 ).The change of GR binding capacity of PMLs was similar to that of MNLs.There was no significant difference of CD4/CD8 ratio between the GC and non-GC group at day 1.The ratio of CD4/CD8 in the non-GC group was significantly higher than that in the GC group at day 10 (P ＜0.05).CD4/CD8 ratio in the GC group showed a slight reduction at day 10,with no significant difference from that at day 1.While,the non-GC group showed a significant increase of CD4/CD8 ratio at day 10 as compared with that at day 1 (P ＜ 0.05 ).ConclusionLow-dose GC plays some role in the negative feedback regulation of GR binding capacity of peripheral blood leukocytes and in the inhibition of cellular immune function.
