Pointing to the contradiction features existent in teaching of clinical practice in the beginning stage of establishing affiliated hospital of university,it primarily discusses the management method in teaching of clinical practice,which gets first achievements after 3-year trial.

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.

Objective To approach the protective actions of Red Rose Capsule for Releasing the Dysmenorrhea(RRC) on the mice of primary dysmenorrhea.Method Sixty four health rats with the similar menstrual cycle were divided into four groups-NS group,RRC low dose group,RRC high dose group and Yueyueshu group.The indexes of TXB2 and 6-Keto-PGF1? in plasma were observed.Result RRC had significant effect on increasing 6-Keto-PGF1 ? and decreasing TXB2 in plasma of primary dysmenorrhea mice.Conclusion RRC has protective action against primary dysmenorrhea by influencing the content of TXB2 and 6-Keto-PGF1?.

Objective To approach the medicine-Schisandraceae-protective actions to the mice of experimental Kidney Yin deficiency from different angles. Method To observe the level of SOD and OFR in the female rats ovary tissue in order to prove the medicine’s curative effect. Result Schisandraceae can obviously increase the SOD and decrease the OFR to experimental Kidney Yin deficiency mice. Conclusion Schisandraceae has very obviously protective action to experimental Kidney Yin deficiency by influencing content of SOD and OFR of female mice ovary tissue.

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.

Objective To evaluate the clinical features,therapies and prognosis in patients with mucosa-assoeiated lymphoid tissue (MALT) lymphoma in ocular adnexal marginal zone (OAML).Methods A retrospective analysis was made upon clinical data from 21 patients with OAML admitted into Beijing Tongren Hospital from June,2008 to December,2011.Results There were 12 (57.1 ％) men and 9(42.9％) women,with a median age of 57 (23-79) years old.Majority of patients had localized pathological changes.Among them,16 patients (76.2％) were in stage Ⅰ E,and 5 (23.8％) in stage Ⅳ E.Surgical resection as the sole treatment was performed in 13 patients (61.9％),and positron emission tomography CT(PET-CT) imaging demonstrated normal fluorine 18-fluorodeoxyglucose (FDG) uptake after surgical resection,who were managed with no further therapy.All the 13 patients were followed up for median 14 (5-38) months,and all in complete remission.Combination chemotherapy was given to 8(38.1％) patients.Three patients in stage Ⅰ E treated with COP (cyclophosphamide,vineristine and prednisone) or CHOP (cyclophosphamide,adriamycin,vincristine and prednisone) were all in partial remission.Five patients in stage ⅣE were treated with COP/CHOP in combination with rituximab,and all in complete remission.The 3-year overall survival rate and disease-free survival rate in the total patients were 100.0％ and 74.9％ respectively.Conclusions The patients with OAML generally have localized disease,show indolent clinical course,and present low lymphoma-related mortality.Surgical resection is a very important treatment in the patients with local disease.Systemic chemotherapy should be considered in patients at advanced stages.Rituximab in combination with chemotherapy can improve the remission rate.

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.
