Detaljeret beskrivelse
38 patients admitted to ICU and 15 healthy volunteers were successively enrolled in this study.The healthy volunteers were treated with endoscopy and biopsy .The 38 patients were treated with bedside gastroscopy and diagnosed with SRMD due to illness.
The acute physiology and chronic health evaluation（APACHE）II score were evaluated, malondialdehyde (MDA) as an index of oxygen radical-lipid peroxidation was assessed in the serum.
Transforming growth factor(TGF)β1,claudin3, interleukin (IL) 1 and interleukin（IL）10 levels in the gastric mucosa and plasma level of superoxide dismutase(SOD)，Ischemic modified albumin(IMA)and C-reactive protein（CRP）were evaluated.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
malondialdehyde (MDA)（nmol/mL）
Tidsramme: Month 1
|
MDA is an index of oxygen radical-lipid peroxidation was assessed in the serum。Thiobarbituric acid （TBA）method was applied for MDA.
|
Month 1
|
|
superoxide dismutase(SOD)(u/mL)
Tidsramme: Month 1
|
The activity of superoxide dismutase(SOD) reflects the the antioxidant ，capacity.Pyrogallol substrate method was applied for SOD.
|
Month 1
|
|
claudin3
Tidsramme: Month 1
|
Tight junctions (TJs) are the most apical component of the intercellular junctional complexes.
TJs consist of occludin, the claudin family of proteins, and junctional adhesion molecule (JAM).Among these TJ molecules, claudins are major integral membrane proteins of TJ strands.Studies have shown that H2O2 can change the number of claudin-3.Previously in vitro experiments have reported that H2O2 increases the permeability of the epithelial monolayer by splitting the cell-tight junction complex structure.
In our study,the claudin3 in gastric mucosa was measured by western blot method.
|
Month 1
|
|
TGFβ1
Tidsramme: Month 2
|
Measurement of TGFβ1 in gastric mucosa by immunohistochemistry method and microscopic observation.Image-Pro Plus 6.0 software was used to select the same brownish yellow as a uniform standard for determining the positiveness of all photographs.
Each photo was analyzed to determine the cumulative cumulative optical density of each photograph.We may collect serm to test TGFβ1 using ELISA method，or we may omit this step.
|
Month 2
|
|
Acute physiology and chronic health evaluation（APACHE）II score
Tidsramme: Month 3
|
Acute physiology and chronic health evaluation（APACHE）II score was completed within 24h after admitting, including 12 physiological parameters (each item 0-4 points, total score 0-60 points), age (0-6 points) and chronic disease health status (2-5 points).
The total score was 0-71 points.
The higher the score, the more severe the illness will be.
|
Month 3
|
|
interleukin（IL）1β
Tidsramme: month 4
|
Measurement of interleukin（IL）1β in gastric mucosa by immunohistochemistry method.Image-Pro Plus 6.0 software was used to select the same brownish yellow as a uniform standard for determining the positiveness of all photographs.
Each photo was analyzed to determine the cumulative cumulative optical density of each photograph.We may collect serm to test IL1β using ELISA method，or we may omit this step.
|
month 4
|
|
interleukin（IL）10
Tidsramme: Month 5
|
We measure interleukin（IL）10 in gastric mucosa by immunohistochemistry method.Image-Pro Plus 6.0 software was used to select the same brownish yellow as a uniform standard for determining the positiveness of all photographs.
Each photo was analyzed to determine the cumulative cumulative optical density of each photograph.We may collect serm to test IL10 using ELISA method，or we may omit this step.
|
Month 5
|
|
Nitric oxide synthasei（iNOS）
Tidsramme: Month 6
|
Measurement of inducible nitric oxide synthasei（iNOS ）in gastric mucosa by immunohistochemistry method.Image-Pro Plus 6.0 software was used to select the same brownish yellow as a uniform standard for determining the positiveness of all photographs.
Each photo was analyzed to determine the cumulative cumulative optical density of each photograph.
