Objective To prevent and manage spinal ischemia caused by cross-clamping the thoracoabdominal aorta often undertaken in clinical surgical practice. Methods Forty-five rabbits were divided for 3 experiments. A variety of vasoactive agents were used to manage spinal ischemia; The effect of cerebrospinal fluid drainage was evaluated; Hypothermia was used to alleviate the spinal ischemia injury. Results Among the above three experiments neuron degeneration was the mildest in hypothermia group though prostaglandin and cerebrospinal fluid drainage do have some positive effects. Conclusion It was suggested that administration of hypothermia and prostaglandin are the most effective for the prevention of spinal ischemic injury during major thoracoabdominal aorta surgery.

Objective To explore the complication s and management of the placement of vena caval filter in patients suffering from deep venous thrombosis (DVT). Methods From 1998 to 2005, 80 DVT patients were treated by vena caval filte r placement. Before the placement 46 cases received CTA, 27 cases did radionucli de imaging(LPS), 16 cases did color Doppler ultrasonography, 5 cases underwen t venography. Result The p rocedure was successful in all 80 cases. New DVT developed in contralateral fem oral vein in 2 patients and vena caval obliteration developed in 3 patients afte r one year. Conclusion The complications of vena caval filter placement could be prevented by correctly de fine indication and good expertise.

Objective To make a clinical and mycological analysis of tinea capitis in Guangzhou region. Methods A retrospective analysis was performed on 241 cases of tinea capitis collected from Feb, 1997 to Aug, 2010 in the Department of Dermatology, Sun Yet-sen Memorial Hospital. Results Among the 241 cases, 179 (74.27%) were tinea alba, 34 (14.11%) tinea kerion, 28 (11.62%) black dot ringworm, and no favus was observed. The dominant pathogenic fungi in decreasing order were Microsporum canis (182,80.89%), Trichophyton violaceum (25, 11.11%), Trichophyton mentagrophytes (10, 4.44%), Trichophyton tonsurans (3, 1.33%), Trichophyton rubrum (2, 0.89%), Microsporum gypseum (2, 0.89%) and Trichophyton verrucosum (1, 0.44%). Children were the main population (39.00%) suffering from tinea capitis. Conclusions In Guangzhou region, tinea alba is the most common type of tinea capitis, Microsporum canis is the main causative pathogen, and children are the predominate population affected by tinea capitis.

Objective To summarize experience in treating patients with native value endocarditis ( NVE) , and discuss the effect of timing of surgery on the infection control , cardiac function recovery and long-term mortality among patients . Methods Eighty NVE cases with antibiotic treatment were recruited between January 2006 and May 2013 .According to the timing of surgery, the subjects were divided into the early surgery group (38 cases) and the late surgery group (42 ca-ses) .The infection-related markers and cardiac function indexes before and after surgery , and 1-year, 3-year and 5-year mortality after surgery were analyzed .Results The infection control and recovery of cardiac function in the early surgery group were better than in the late surgery group (P<0.05).The difference in 3-year and 5-year mortalities between the two groups was significant .Conclusions For NVE patients with routine antibiotics treatment , the surgical effect and long-term survival rate are much better in the early surgery group than in the late surgery group .

A method was developed for the determination of four kinds of bisphenolic and halogenated bisphenolic compounds including bisphenol F, bisphenol A, tetrachlorobisphenol A, tetrabromobisphenol A in human urine using high performance liquid chromatography-tandem mass spectrometry. The analytes was extracted by solid phase extraction. The separation of the analytes was achieved on an Atlantis T3 column (3. 0×150 mm, 3 μm) gradient eluted with the mobile phase of acetonitrile and water at the rate of 250 μL/min, and detected by an electrospray ionization tandem mass spectrometry in the multiple-reaction-monitoring negative mode. The quantification was carried out by matrix-matched calibration curve. The average recoveries at 3 spiked levels were 86%-118%, with intra-day precision of 2 . 6%-17 . 0% and inter-day precision of 3. 2%-18. 0%. The limits of detection of four analytes (S/N=3) were 0. 01-0. 25 μg/L. The method was applied to the analysis of 200 human urines samples and the results showed that the method was simple, sensitive and reliable.

Objective To evaluate the role of complement receptor 3 (CR3) on murine macrophages in the recognition of Penicillium marneffei.Methods RAW264.7 murine macrophage cells were cultured in vitro,and divided into four groups to be cocultured with inactivated and live Penicillium mameffei yeast cells as well as inactivated and live Penicillium marneffei conidia respectively at 37 ℃ in 5％ CO2 for one hour.The RAW264.7 cells incubated with phosphate-buffered saline (PBS) served as the blank control group.Then,reverse transcription-PCR was conducted to detect CR3 mRNA expression,Western blot to measure CR3 protein expression,flow cytometry to determine phagocytosis rate,enzyme-linked immunosorbent assay (ELISA) to quantify cytokine levels in culture supernatant.Some RAW264.7 macrophages were transfected with a specific siRNA targeting CR3 gene and cocultured with inactivated Penicillium marneffei conidia,subsequently,phagocytosis rate and supematant cytokine levels were determined.Data were processed by the SPSS 16.0 software,and one-way analysis of variance (ANOVA) was conducted for inter-group comparisons of these parameters.Results No significant differences were observed in the mRNA or protein expressions of CR3 among the four groups of RAW264.7 cells cocuhured with different forms of Penicillium marneffei (both P ＞ 0.05).The phagocytosis rate was 95.14％,89.56％,91.03％ and 90.78％ in RAW264.7 cells cocultured with inactivated conidia and yeast cells,as well as live conidia and yeast cells of Penicillium marneffei,respectively (P ＞ 0.05).The levels of interleukin (IL)-2,interferon (IFN)-γ,IL-4 and IL-10 in culture supernatant were increased at different degrees after one-hour coculture in the four coculture groups compared with the blank control group,but no statistical difference was noted among the four coculture groups in the supernatant levels of these cytokines (all P ＞ 0.05).After coculture with inactivated Penicillium marneffei conidia,the siRNA-transfected RAW264.7 cells showed a statistical decrease in phagocytosis rate (10.89％ vs.92.78％,P ＜ 0.05) and supernatant levels of IL-2,IFN-γ IL-4 and IL-10 compared with untransfected RAW264.7 cells.Conclusions In early stage of innate immunity,CR3 on macrophages may be one of the pattern recognition receptors participating in the recognition and mediation of phagocytosis of Penicillium marneffei.It's possible that both Thl-and Th2-type cytokines,such as IL-2,IFN-γ,IL-4 and IL-10,are involved in the immune response of macrophages against Penicillium marneffei.
