Objective To explore the reparative effect of bactericidal/permeability-increasing protein(BPI) on the damaged mucosa of rats with otitis media with effusion (OME),and state the pathogenesis of OME.Methods Wistar rats(40 ears) were randomly divided into six groups:normal control group (n=4),BPI control group(n=4),eustachian tube obstruction (ETO) group (n=8),lipopolysaccharide (LPS) injection group (n=8),ETO+LPS group (n=8),ETO+LPS+BPI group (n=8).The experimental OME model was made through eustachian tube obstruction and LPS injection.The rats were killed after 1,2 and 4 weeks and the changes of mucosa of middle ear were observed under light and scanning electron microscope.Results The rats in normal control group and BPI control group had the normal mucosa in the tympanic orifice of the eustachian tube.It consisted of pseudostratified ciliated cubical or columnar epithelium which contained an abundant number of ciliated cells and a few goblet cells,these were the mucociliary clearance system of the middle ear.The hypotympanum consisted of thin,squamous epithelium with few microvillus.Middle ear mucosa was obviouly thickened in LPS injection,ETO and ETO+LPS groups.An increase in goblet cells and a decrease in ciliated cells were observed in the tympanic orifice of the eustachian tube.The epithelial layer in the hypotympanum had become more pseudostratified ciliated cubical epithelium.In ETO+LPS+BPI group,there was thin squamous epithelium in the hypotympanum near normal,which was not thickened and contained few microvillus. Conclusion LPS and ETO can result in the occurrence and protracted courses of OME by mimosa's inflammatory reaction which can reduce the activity of ciliary cells and weaken the function of mucociliary clearance system.BPI could bind avidly to LPS,reduce inflammatory reaction,and break the inflammatory cycle and reestablish an effective mucocillary clearance system.The results suggest that BPI treatment is a potential effective drug for prevention and therapy of chronic OME.

Mortality of patients with malignant middle cerebral artery infarction (mMCAI) is as high as 41% to 78% with the conservative treatment in the intensive care unit.Malignant edema caused tentorial herniation is the most common cause of resulting in the death of patients.Some evidence supports the hemicraniectomy for the treatment of patients with mMCAI.The patients must receive supportive and adjuvant therapies before surgical decision making.Therefore,the prediction and intensive care of mMCAI have a very important significance.This article reviews the predictive factors and intensive care of mMCAI.

Many studies have shown that chronic inflammation occurs in the brain of patients with Alzheimer's disease (AD). It is well known that long-term administration of non-steroidal anti-inflammatory drugs (NSAIDs) can alleviate the cognitive decline of AD patient and elderly. Several inflammatory cytokines produced in the metabolism of arachidonic acid (AA) are closely related to inflammatory diseases. Lipoxygenases (LOXs) and cyclooxygenases (COXs) play a crucial role in the AA network, the products eicosanoids have an important impact on the progression of AD. Although there are many arguments and conflicting evidence, currently LOXs and COXs are still the hot topics in the research on AD pathogenesis and drug development. Here, we review the progress in research on COXs and LOXs, including their actions on CNS and their association with AD, and explore the feasibility of LOXs and COXs as targets for the drugs to prevent and/or treat AD.

Objective To compare the safety and effectiveness of two methods of perineal dissection in 60 consecutive patients of rectal carcinoma undergoing combined abdominoperineal resection.Methods In this retrospective study from 2007 to 2009, 30 cases underwent Miles' operation using modified method of perineal dissection( MM group) and 30 cases undergoing Miles' operation using classic method of perineal dissection ( CM group). Operative time, accidental tumor ( or rectal) perforation during the procedure, iatrogenic injury to the urethra ( or vagina) and postoperative perineal complications were compared between the two groups. Results The mean perineal operative time was (45±15) min in MM group and ( 70 ± 20) min in CM group respectively ( t = 5. 48, P < 0. 05 ). There were no significant differences in the rate of tumor ( or rectal) perforation and that of urethral (vaginal) injury. There were significant difference in the rate of postoperative perineal complications (χ2=4.01, P<0.05).Conclusions Modified method of perineal dissection is effective and safe, and this method offers a new approach for the perineal dissection during Miles' operation.

BACKGROUND:Previous in vitro studies mainly focused on morphological and nerve marker aspects in the study of bone marrow mesenchymal stem cells (BMSCs)-derived neuron-like cells,but less focused on the olectrophysiological properties of neuron-like cells following differentiation.OBJECTIVE:To study the electrophysiological changes of differentiation from BMSCs into neuron-like cells after induction by brain-derived neurotrophic factor (BDNF)/basic fibroblast growth factor (bFGF)/alltrans-retinolc acid (AT-RA).DESIGN,TIME AND SETTING:The cytological comparative in vitro study was performed at the Department of Neural Cell Laboratory,Tianjin Huanhu Hospital and College of life Science of Nankai University from June 2005 to October 2007.MATERIALS:Totally 3 male Wistar rats (6-week old,weighing about 160 g) were used in this study.METHODS:BMSCs were cultured and purified by their characteristic of plastic adhesion in vitro,and then induced by BDNF,bFGF and AT-RA,and differentiate into neuron-like cells.Whole-cell patch damp technique was used to detect cell membrane current prior to and 3 days following induction.MAIN OUTCOME MEASURES:MSC phenotype was determined by flow cytometry.Cell morphology was observed under the inverted microscope before and after differentiation.Neuron specific enolase expression was assessed by immunocytochemistry.Whole-cell current results were measured.RESULTS:Flow cytometry results demonstrated that CD90 positive rate (99±3)%,CD31 (3.4±0.8)%,and CD34 (0.3±0.1)%.This indicated that these cells were undifferentiated stem cells,with purity of 95%.Undifferentiated MSCs under the optical microscope were mostly fiat cells with processes,similar to fibroblast-like cells.Neuron-like cells appeared 3 days following induction.Immunocytochemistry results showed that MSCs before induction were weakly positive for neuron specific enolase,but strongly positive for neuron specific enolase.At 72 hours,the differentiated rate was (24.01±3.76)%.The peak currents of outward currents in neuron-like cells were significantly higher in the induction group compared with the control group (P < 0.05),but no inward Na~+ current was detected.CONCLUSION:(bFGF & BDNF)/AT-RA could induce the differentiation of MSCs into neuron-like cells.These cells showed the tendency to differentiate into mature neurons,though having no electrophysiological properties of mature neurons.
