Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2006;0(03):-
Objective: To investigate the relationship between circulating endothelial cell(CEC)(numbers),blood lipid levels and multiple organ dysfunction syndrome(MODS) and their clinical(significance).Methods: CECs were separated by isopyknic centrifugation method and blood lipid was(determined) in(35 MODS) patients and 20 healthy controls.CEC numbers and blood lipid were compared in both groups.(Acute) physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score was recorded to evaluate the severity of the MODS patients.The relationships were analyzed between APACHEⅡ score and CEC numbers,(between) APACHEⅡ and blood lipid levels and between CEC numbers and blood lipid levels.Results: CEC numbers in MODS patients were significantly higher than those in healthy controls(P

Objective To investigate the effects of rosiglitazone,an agonist of proliferators activated receptor?(PPAR?),on expression of nuclear factor-kappa B(NF-?B)in peripheral blood mononuclear cells(PBMC)of multiple organ dysfunction syndrome(MODS) rats.Methods Forty male SD rats were randomly divided into four groups(n = 6 per group): vehicle control group,endotoxin(LPS) group,rosiglitazone(ROSI) pretreatment group,and PPAR-?antagonist GW9662 pretreatment group.Blood was taken 4 hours after operation,and mononuclear cells were separated.The expression of NF-?B p65in PBMC was detected by immunocytochemical method and image analysis was carried out.Results The expression of NF-?B p65 was low in vehicle control group.In LPS group,the expression of NF-?B p65 was significantly higher than that in vehicle control group(P0.05).Conclusion Rosiglitazone protected the MODS rats by inhibiting NF-?B activation.

Objective To investigate the clinical value of color Doppler flow imaging(CDFI) in the diagnosis and clinical follow-up of retinopathy of prematurity(ROP).Methods From March 2008 to February 2009,98 eyes of 49 premature infants(gestational age≤37 weeks,or birth weight≤2 000 g) underwent ROP screening by RetCam digital retinal camera and indirect ophthalmoscopy in the fourth to sixth postnatal week.At the same time,they were also examined by 8-14 MHz CDFI.Results Determined by RetCam digital retinal camera and indirect ophthalmoscopy,ROP was found in 41 eyes,including 8 eyes at stage Ⅰ,19 eyes at stage Ⅱ,6 eyes at stage Ⅲ,8 eyes at scarring stage and no eye at stage Ⅳ andⅤ.Compared with ophthalmologic examination,the specificity of CDFI for ROP diagnosis was 85.5%,and the sensitivity was 76.7%.Detected by CDFI,typical changes were not found in the infants with ROP at stage Ⅰ.In the infants with ROP at stage Ⅱ and Ⅲ,abundant blood flow signals were found in the central retinal artery(CRA).Increased amounts of the small vessels and irregular circuitousness were also observed.There was no obvious change in the systolic velocity(VS) of CRA.The diastolic velocity(Vd) was decreased and the resistance index(RI) was increased.A strong zonal echo protruded into the vitreum.Small blood flow signals which came from CRA by tracing toward their distal end were found in the same position using CDFI.Conclusions Detected by CDFI,the sonographic features of infants with ROP at stage Ⅰ are not typical,but those of infants with ROP at stage Ⅱ and Ⅲ are specific.CDFI is valuable in clinical ROP screening of high risk group.

BACKGROUND: The expression and significance of transforming growth factor-alpha (TGF-α) and epidermal growth factor receptor (EGF-R) in different diseases are different.OBJ ECTTVE: To investigate the expression of TGF-α and EGF-R in human liver cirrhosis tissues.DESIGN : Non-randomized controlled trial.SETTING: Department of General Surgery, Tangdu Hospital, Fourth Military Medical University of Chinese PLA.MATERIALS: This trial was carried out in the Department of Pathology, Xijing Hospital, Fourth Military Medical University of Chinese PLA during March 2003 to May 2004. Sixty-three samples of human liver cirrhosis tissue were obtained from Department of General Surgery, Xijing Hospital, Fourth Military Medical University of Chinese PLA (Informed consents were obtained). Five human normal liver tissues were obtained form autopsy in Department of Pathology, Fourth Military Medical University of Chinese PLA (patients with liver diseases were excluded).METHODS: Sixty-three samples of human liver cirrhosis specimens and five human normal liver tissues were studied with immunohistochemical method and in situ hybridization technique. The positive rates of TGF-α and EGF-R were calculated and managed statistically.MAIN OUTCOME MEASURE: Detection of the expressions of TGF-α and EGF-R in liver cirrhosis tissues were detected with immunohistochemical method and in situ hybridization technique.RESULTS: The expression rate of TGF-α and EGF-R in 63 samples of human liver cirrhosis tissues was 84% (53/63)and 52% (33/63) respectively. These positive granules were brown and most of them were in cytoplasm of hepatocytes.There was significantly positive correlation between TGF-α and EGF-R (r =0.32,P < 0.05). In five normal liver tissues,TGF-α and EGF-R were not detectable in hepatocytes and bile ducts. In situ hybridization showed the levels of TGF-αmRNA and EGF-R mRNA were higher (86%, 54%) than those of immunohistochemistry. There was no significant difference between two detective methods (P>0.05).CONCLUSrON: Liver cirrhosis might be under the autocrine regulation of TGF-α/EGF-R. Increasing expression of TGF-αand EGF-R might be one of important factors in liver cirrhosis pathogenesis.
