The diagnosis of myocardial damage in systemic lupus erythematosus(SLE) is mainly based on clinical symptoms,physical examinations and electrocardiographic abnormality,echocardiographic changes,and myocardial enzymologic diversity in general.In recent years,it has been suggested that cardiac troponin I possesses high sensitivity and specificity in the diagnosis of myocardial damage.Lupus myocardial damage is diagnosed definitively depending on endomyocardial biopsy.Its treatment has been empirical,and hormone combined with immunodepressive is routine treatment.According to pathogenetic condition,there are still several therapies such as intravenous immunoglobulin therapy,blood purification and autologous hematopoietic stem cell transplantation,extracorporeal membrane oxygenation,and so on.Most often,myocardial dysfunction in SLE is of subclinical progression,and that early diagnosis and prompt treatment may play an important role in relieving patients' condition,raising quality of life and improving prognosis.

Chronic cerebral hypoperfusion is a common pathological state. Cognitive impairment is its main manifestation in early stage, and it will eventually result in persistent or progressive cognitive impairment and neurological deficits. Chronic cerebral hypoperfusion caused neuronal damage, synapse abnormity, energy impairment and the function defects of central cholinergic system and monoaminergic system are its pathophysiological mechanisms resulting in cognitive impairment.

AIM: To study the clinical characteristics of corneal perforation ( CP) .
METHODS:A retrospective analysis in July 1995 to July 2010 the First Affiliated Hospital of Fujian Medical University diagnosed CP 72 patients ( 72 eyes ) , clinical characteristics of all the patients were analyzed.
RESULTS: The incidence of corneal ulcer perforation rised year by year, the morbidity of male and female was 17:7, the onset age focused on 48 years old. Of 23 industrial workers ( 32%) with clear history of trauma, pathogeny identification results:top two:fungal infection and Acanthamoeba keratitis. A using history of glucocorticoid was found in 10 cases.
CONCLUSION:There are plenty of primary causes of CP such as traumas, fungal infection, Acanthamoeba keratitis, eroded keratitis, etc. CP happens in middle-aged males in Fujian province, most traumas are the causes, the main pathogenic bacteria is fungal infection.

BACKGROUND:It has been recently indicated that nervous factors are able to adjust and dominate bone fracture healing. Type Ⅰ collagen is a major factor to promote the differentiation of osteoblasts and enhance the adhesion of osteoblasts; while, it is also a matrix protein for composing bone framework. Type Ⅱ collagen is derived from chondrocytes. OBJECTIVE: To study changing law of type Ⅰ and Ⅱ collagen expression during denervated bone fracture healing. DESIGN, TIME AND SETTING: Randomized controlled anima study was performed at the Animal Laboratory and Cell Biology Laboratory, the Second Military Medical University of Chinese PLA between May and December 2005. MATERIALS: Forty 3-month-year healthy male SD rats were randomly divided into fracture group (tibial fracture alone) and combination group (spinal cord injury combined with tibial fracture), with 20 rats at each group. METHODS: A φ 0.8 mm Kirschner wire was inserted into anterior border of left tibial plateau to establish tibial fracture models in the fracture group. A 0.3-cm spinal cord transection was cut at T10 segment to establish tibial fracture models with entire spinal cord injury. MAIN OUTCOME MEASRUES: Type Ⅰ and Ⅱ collagen protein expressions of callus were detected using Western blot technique in week 1, 2, 4, and 5 post-injury. RESULTS: One week after injury, type Ⅰ and Ⅱ collagen was represented in callus in the two groups, while the expressions in the combination group were significantly higher than fracture group (P<0.05); two weeks after injury, type Ⅱ collagen expression reached at the peak in the combination group, and the expression was significantly higher than the fracture group (P<0.05); four weeks after injury, type Ⅰ collagen expression reached at the peak in the fracture group, and the expression was significantly higher than the combination group (P<0.05), while type Ⅱ collagen still highly expressed in the combination group; five weeks after injury, type Ⅰ and Ⅱ collagen expressions were decreased in the two groups. CONCLUSION: Secretory law of type Ⅰ and Ⅱ collagen during denervated bone fracture healing is similar to normal bone fracture healing; however, the differences at time points, in particular expression at peak, are remarkable between them.

Objective To study the inhibitory effect of panax notoginseng saponins (PNS) on 3-nitrotyrosine (3-NT) formation in brain induced by heme/NO2 -/H2O2 or ONOO - pathways in vitro. Methods According to the two major pathways of 3-NT formation in vivo, the models of protein nitration induced by heme/NaNO2/H2O2 or ONOO-system were established, respectively, in vitro. Bovine serum albumin (BSA)/rat plasma protein or rat brain homogenate protein were utilized as reactive substrates in both systems. Samples were divided into blank-control group, 3-NT group and PNS group (including low-, medium-and high-concentration subgroups). In 3-NT group, samples were exposed to heme/NaNO2/H2O2 or ONOO-system, respectively, at 37℃for 30 min, whereas in PNS group, samples were pre-incubated with PNS (at final concentrations of 50 mg/L, 100 mg/L, and 200 mg/L) at 37℃for 5 min before the nitrating system exposure. The 3-NT level in each group was detected by Western blot assy. Results Compared with the blank-control group, both heme/NaNO2/H2O2 and ONOO-system can induce significant 3-NT generation in BSA/rat plasma protein or rat brain homogenate protein (P<0.05). Compared with model group, PNS pre-treatment markedly inhibited 3-NT expression in BSA/rat plasma protein in a dose-dependent manner (P<0.05), the inhibitory effect of low intervention on the level of 3-NT in rat brain homogenate protein was not significant (P>0.05). Medium- and high-concentrations of PNS pre-treatment markedly inhibited 3-NT accumulation, with maximum effect at the concentration of 200 mg/L (P<0.05). Conclusion Medium- and high-concentrations of PNS can inhibit 3-NT formation in brain tissue mediated by either heme/NO2-/H2O2 or ONOO-pathways, implying that potential neuroprotective action against 3-NT involves pathological conditions, like trauma, stroke, and neurodegenerative diseases.

Objective To investigate the effect of Yiqi Huoxue Huatan Decoction(YHHD) on gene expression of vascular endothelial growth factor(VEGF), intercellular adhesion molecule 1(ICAM-1) in the colonic mucosa of ulcerative colitis rats. Methods Sixty rats were divided into six groups, namely normal control group, model control group, low-, middle- and high-dose Y HHD group(gastric gavage of YHHD in the dosage of 13, 26, 52 g·kg-1·d-1 respectively) , and Mesalazine(0.5 g·kg-1·d-1 ) group. T he rat model of ulcerative colitis was established by enema with 2, 4, 6-trinitrobenzene sulfonic acid(TNBS)mixture(2.5%TNBS and 50% ethanol). The changes in rat body weight were monitored. After treatment, pathological features of the colonic mucosa were observed under light microscope, and VEGF and ICAM-1 gene expression levels in the colonic mucosa were measured by reverse t ranscripti on polymerase chai n reaction(RT-PCR). Results Body weight was lighter, and relative gene expression levels of VEGF and ICAM-1 in the model group were significantly higher than those in the normal control group, and pathological features of the colonic mucosa was obvious, the differences being significant between the two groups(P<0.01). Compared with the model group, body weight was increased , pathological features of the colonic mucosa were relieved, and relative gene expression levels of VEGF and ICAM-1 were significantly decreased in YHHD groups(P<0.01), and high-dose YHHD showed the strongest effect. Conclusion YHHD can down-regulate the gene expression of VEGF and ICAM-1, which may be one of its therapeutic mechanisms for ulcerative colitis.
