Objective To explore whether dexmedetomidine(Dex)could mitigate acute lung in-jury induced by hind limb ischemia reperfusion(I/R).Methods One hundred and twenty SD rat weigh-ting 250-300 g were allocated to receive hind limb I/R,I/R plus Dex (25 μg/kg Dex was intraperitoneal in-jection 30 min before ischemia)and norm control group,and each group was further divided into five sub-groups:before operation and 4 h ischemia followed by 0,1,3 and 6 h reperfusion.After euthanization,lung W/D weight ratio,PaO2 ,SOD,MDA and TNF-α were determined.Results Compared with group C, hind limb I/R injury significantly increased serum TNF-α concentration and W/D ratio,with significantly decreasing PaO2 level at any time of reperfusion in the group I/R,the concentration of MDA increased and the SOD activity decresed at 1,3,6 h of reperfusion.Conversely,W/D ratio as well as the concentration of TNF-αin the serum of the I/R plus group Dex were significantly lower than those of the I/R at 6 h of reperfusion,PaO2 level increased respectively;the concentration of MDA decresed at 1,3,6 h of reperfusion and the SOD activity increased at 3,6 h of reperfusion in I/R plus group Dex.Conclusion Dex mitigates a-cute lung injury induced by unilateral hind limb I/R in rats.The mechanisms may involve attenuating oxida-tive stress and inhibiting inflammatory response.

Objective To observe the effectiveness of Chinese herbal medicine plus movement therapy in treating upper limb spasticity in hemiplegic patients. Methods Sixty-six patients were divided randomly into two groups. Thirty-five patients in the therapy group were treated with Chinese herbal medicine and movement therapy, and 31 patients in the control group were treated with movement therapy alone. The modified Ashworth scale and sur- face electromyography were applied to evaluate spasticity. Results The total effectiveness rates were 94.3% in the therapy group and 64.5% in the control group. After treatment, the average integrated electromyogram (IEMG) val- ue in the therapy group was lower than that in the control group. The difference in IEMG values before and after treat- ment in the therapy group was significantly larger than in the control group. Conclusion Chinese herbal medicine plus movement therapy is more effective than movement therapy alone in relieving spasticity.

Budd-Chiari syndrome (BCS) is a rare disease. Because of lack of clear characteristic symptoms in the early stage, many patients are misdiagnosed or never diagnosed. Early diagnosis and prompt treatment play a key role in improving survival rates and quality of life for BCS patients. With the progress in imaging techniques, the radiological examination is playing more and more important role in the diagnosis and assessment of BCS. Ultrasound, computed tomography, magnetic resonance imaging and digital subtraction angiography are all helpful in evaluating the obstruction of hepatic vein and inferior vena cava. Thus, these imaging tests should be used rationally according to their features. On the other hand, the interventional therapy is the preferred method for the treatment of BCS. This paper intends to get a deeper understanding of BCS for clinicians, which is essential for patients to be diagnosed in time.

ObjectiveTo explore relations between self-control and aggressive behavior in college students.Methods 310 students were surveyed with Buss-Perry aggression questionnaire and self-control questionnaire(SCQ).Results①High score group in SCQ was higher with physical aggression,verbal aggression,anger,hostility and aggression scores ( respectively ( 25.86 ± 5.04 ),( 15.27 ± 2.76 ),( 20.12 ± 4.26 ),( 23.87 ±4.45 ),( 85.11 ± 11.75 ) ) than the low group ( respectively (20.26 ± 5.04 ),( 14.04 ± 3.35 ),( 13.76 ± 4.68 ),( 19.37 ±5.31 ),(67.43 ± 13.56) ),the difference was statistically significant (P＜ 0.01 ).②Self-control scores had significant positive correlations with aggressive behavior scores( r=0.60,P＜ 0.01 ).③Self-control dimension (self-emotional,simplistic tendency,impulsive risk-taking) were significant predictors of aggressive behavior(P ＜0.01 ).ConclusionSelf-control is closely related with aggressive behavior,and it is a significant predictor of aggressive behavior.

Small intestinal neuroendocrine carcinoma is poorly differentiated,highly malignant,and originated from the diffuse neuroendocrine system.It diffusely expresses the general neuroendocrine differentiation markers.The disease can be manifested as carcinoid syndrome,but most of the patients were with occult onset and absence of specific clinical symptoms,which led to difficult diagnosis before operation.On June 18,2012,a patient with manifestation of recurrent vague abdominal pain received capsule endoscopy at the Northern Jiangsu People's Hospital.The capsule endoscope was retained in the distal small intestine,and malignant ileum lesion was revealed during the surgical exploration.Finally,poorly differentiated neuroendocrine carcinoma with abdominal wall metastases was identified by pathological examination.

This paper analyzed the characteristics of pathophysiology teaching for Mongolian students.Exploration was made in aspects of designing,implementing and evaluating multilingual pathophysiology teaching mode for Mongolian students.The problems of the mode were summarized and optimization measures were proposed.

The clinical course of mycosis fungoides is indolent except when large cell transformation occurs. Large cell transformation of MF is rare and easy to misdiagnose. A case of large cell transformation of mycosis fungoides is reported. A 40-year-old man presented with a 10-year history of pruritic erythema and papules in the trunk and extremities as well as a 5-month history of nodules on the nape of the neck.Histopathologically, the erythematous patch showed typical changes of mycosis fungoides, while the tumor cells were small and expressed CD3 and CD4, and only a small number of tumor cells expressed CD30. Pathological examination of nodular lesions revealed the infiltration of large pleomorphic lymphoid cells expressing CD3 and CD4 throughout the entire dermis. There was an epidermotropism of large cells, and about 40% of these cells expressed CD30. Based on the medical history and histological findings, the patient was diagnosed with large cell transformation of mycosis fungoides. The lesions improved markedly after 3-week treatment with oral acitretin (30 mg once daily), subcutaneous interferon-alpha (2 × 106 IU thrice a week) and local superficial X-ray irradiation for nodular lesions. Up to the time of this writing, the patient had been followed.

A piece of news was introduced into pharmacology course examination.Students were asked to make comments on the news based on pharmacology knowledge or principles.All points of view were summarized and given back to the students after the examination. The right way to answer the question was discussed and a consensus on the answer was reached.lt was indicated that the teaching method in the trial is helpful for improvement of students' overall analytical skills.

Objective To study the protective effect on CCl4-injured L-02 hepatocytes of polysaccharides from Hyriopsis cumingii(HCP) and try to explain the mechanism.Methods The L-02 hepatocytes were incubated and then injured by CCl4.The levels of AST,ALT,MDA and SOD in cultural supernatant were detected by general methods.Cell viability was assayed by MTT method.Results The polysaccharides(25,250 and 1000?g?L-1)could reduce the levels of AST,ALT,MDA in cultural supernatant which increased by CCl4.It also could boost the hepatocytes viability and elevate the level of SOD which reduced by CCl4.Conclusion The results suggest that polysaccharides from Hyriopsis cumingii have direct protective activity on hepatocytes injured in vitro.It might be associated with the anti-oxidative activity of polysaccharides from Hyriopsis cumingii.
