The liquid-chromatography-mass technology was used in the metabolomic analysis of mouse's blood 1 hour after exhaustive exercise,in order to explore the potential mechanism of Rhodiola in fatigue elimination of exhaustive exercise mouse.The exhaustive mouse model was made by loaded-swimming.A total of 24 mice were randomly divided into theRhodiola + exercise group,exercise group andno-exercise group.The dose of Rhodiola was 0.4375 g·kg-1·d-1.The loaded-swimming was conducted after two successive weeks of medication.Blood was collected 1 h after swimming for the sample preparation.The enzyme assay and anthrone colorimetry were used to test blood lactate acid and glucose,respectively.UFLC-Q-TOF was used to detect metabolic profiles of each group.The principal component analysis (PCA),orthogonal partial least squares discriminant analysis (OPLS-DA) and heat map analysis were used to compare differences among groups with score chart and to obtain the characteristics biomarkers by load chart.The results showed that the blood lactate acid level of theRhodiola+ exercise group was significantly lower than that of theexercise group.And the glucose level of theRhodiola+ exercise group was significantly higher than that of theexercise group.The metabolomic analysis showed that there were no obvious changes on 1,25-(OH)2D3,diacylglycerol (DG) and inositol triphosphate (IP3).All three materials in theRhodiola + exercise group were significantly lower than those of theexercise group.They were much closer to theno-exercise group.And all three materials were related to the increasing of muscle tension.It was concluded that Rhodiola had the function of promoting fatigue eliminating.This effect may be related to cell membrane protection,regulation of 1,25-(OH)2-D3→IP3,DG pathway,and relieving of muscle tension after exercises.

Background Phlyctenular ophthalmia is a delayed hypersensitivity reaction to some microprotein and affected mainly by adolescent in high incidence.Objective This study was to investigate the microscopy findings of phlyctenular ophthalmia and evaluate the histological changes by laser scanning confocal microscope.Methods Twenty-nine eyes suffered from phlyctenular ophthalmia and twenty normal eyes were examined using laser scanning confocal microscope.The pictures were taken by a CCD camera.All the cases had initially chest X-ray,tuberculin test,bacterial and mycobacteria culture.Results Dendritic and inflammatory cells were increased and concentrated in conjunctiva,and epithelial cells were deformed and squamatizated.The capillaries engorged and the goblet cells were injured.The corneoscleral Vogt meshing of the phlyctenular keratitis was obscured and dendritic cells were intruded into the corneas.The corneal epithelium of phlyctenular keratitis was absent and the subepithelial nerve plexus were bended and fractured,and the dendritic and inflammatory cells were intruded.Scarring of corneal stroma was seen under the laser scanning confocal microscope.Conclusions Laser scanning confocal microscopy is valuable for basic research and clinical diagnosis of phlyctenular ophthalmia.

Objective To explore the recuperative effect of immunological function and nutritional status on the patients treated by immune enteral nutrition in early stage after severe multiple injury (SMI). Method The patients with SMI,in department of Trauma Surgery,Tongji Hospital,Tongji Medical College, Huazhong University of Science and Technology,between January 2006 to May 2007 were randomly divided into 2 groups: immune enteral nutrition group (IEN group, 20 cases), enteral nutrition group (EN group, 20 cases). The health persons served as the control group(15 cases) .Since 1st postinjury day, all patients were treated with nutritional support. The T-cell subgroup in periphera blood were detected by FCM and the level of PA, RBP, IL-2 and IL-4 in blood serum were detected by ELASA on the 1st, 3rd,5th, 8th postinjury day. Results After the treatment of IEN and EN,the serum levels of PA, RBP and the proportion of T-cell subgroup were significantly increased on the 8th postinjury day compared with on 1st postinjury day (P ＜ 0.01), but there were no differences between IEN group and EN group. The level of IL-4 were significantly decreased and the level of IL-2 were significantly increased in each group on 8th postinjury day, at same time, the level of IL-2 were significantly increased in IEN group compared with EN group (P ＜ 0.05), and the level of IL-4 were significantly decreased in IEN group compared with EN group (P ＜ 0.05). The duration of SIRS was transient and the infected complication was low on the patients treatment by IEN than EN. Conclusions On the patients with severe multiple injury, IEN was most ascendant than EN to improve the immunosuppression and clinical prognosis.

This paper is to explore changes of intestinal mucosal barrier, intestinal flora, and bacterial translocation in rats with severe acute pancreatitis (SAP). Twenty four male SD rats were randomly divided into the control group (n = 10) and the experimental group (n = 14). The model of severe acute pancreatitis of rats was induced by the method of injecting adversely 5% sodium taurocholate into the common biliary-pancreatic duct. All of the rats were killed after 24 hours and the level of the serum amylase and the plasma endotoxin was determined after that. The pathological changes of pancreas and small intestine were observed through hematoxylin-eosin staining (HE staining) and the abdominal viscera bacterial translocation rates were tested. With the method of real-time polymerase chain reaction (RT-PCR) the quantity of the intestinal flora was analyzed. In the control group, the level of Escherichia coli, Lactobacillus and Bifidobacterium were 2.08 ± 1.29, 11.04 ± 7.55 and 12.21 ± 4.95, respectively. On the contrast, the level of Escherichia coli in the cecum contents was much higher (9.72 ± 3.58, P < 0.01), while the Lactobacillus number was decreased significantly (0.67 ± 0.34, P < 0.01), and the Bifidobacterium number was also decreased (4.59 ± 3.42, P < 0.05) in the experimental group, so the ratio of Bifidobacterium/Escherichia coli was reversed. Besides, in the experimental group, the plasma endotoxin positive rates and the bacterial translocation rates were much higher (P < 0.01 or P < 0.05) and the pathology scores of pancreas and small intestines were also significantly higher (P < 0.01) than those in the control group. These results indicated that in severe acute pancreatitis rats, the intestinal mucosal barrier was severely damaged and the dysbacteriosis occurs in the intestinal canal. And these might relate to the occurrence and development of multiple organ infection.

Pathology is a subject that studies the etiology,pathogenesis,pathological changes,progression and outcome of diseases.Pathology links the basic research and clinical practice and is an important part of translational medicine.In order to cultivate qualified pathological graduates with solid pathological theories and the abilities of proposing and addressing scientific hypotheses from pathological morphology changes,we employ modularized special training to divide the pathology training courses into morphology learning module,article searching and reading module,project design module,experiment operation module and scientific presentation module.The training contents among these modules are relatively independent but closely connected,and compose a strategy that aims to improve the scientific innovation ability of pathological graduates.
