This paper is aimed to promote the learning interest and motivation of students and improve the teaching effect, then the interactive courseware of analysis of abnormal gait is done. A courseware should emphasize particularly on optic analysis of abnormal gait, which is closely related to clinical medicine. The interactive courseware was organized with Office 2000, Photo shop 7.0, 3D Studio MAX 3.0 and Hero Super Player 6.5, in which several materials were included, such as the video kinescope of abnormal gaits, clinical features, analysis of mechanics, etiologic analysis and rehabilitation measures of abnormal gaits. There are some pushbuttons in the courseware to achieve controls, such as play, pause, speed, recoil and return end. A majority of students believe that their learning interests of the abnormal gait analysis are improved and have a perceptible idea about abnormal gait that is abstract and vague.

Objective To investigate possible nerological origination of rabbit P3a potential. Method we simultaneously recorded the ERPs at dura and various depths beneath the skull in a point of rabbit skull, similarly did some in different points of rabbit skull. Result In the Brodmann 25 and 32 areas(AcgI), the polarity of P3a to those at dura was markedly reverse and the reverse rate of P3a(81.3%) was significantly higher than other locations, the P3a without polarity reversal showed steep voltage gradient. There was an increasing trend of the P3a reversal and moderate voltage gradient nearby the AcgI, but not other regions. Conclusion Rabbit P3a potential possibly originate from the AcgI acea.

Objective To investigate the generative and regulatory effects of AchMR on P 3a and its mechanism in different subregions of rabbit cingulate gyrus. Methods Event related potentials(ERPs) P 3a potentials in Normal, AcgI, AcgⅡand Pcg regions were recorded after microinfusion of 0.5 mmol/L scopolamine at three different time points(instantly, at the 15th minute and at the 30th minute), 2 mmol/L acetylcholine and 1 mmol/L scopolamine. Results The P 3a amplitude decreased and/or P 3a latency increased with scopolamine in time and dose dependent pattern in AcgⅠ, AcgⅡ and Pcg, and P 3a might disappear only in AcgⅠ and the P 3a again be recorded after microinfusion of acetylcholine in AcgⅠ. Conclusion The action of AchMR in AcgⅠ area markedly affects the generation and/or regulation of P 3a and confirms the AcgⅠ is the source of rabbit P 3a potential. The action of neurons in AcgⅠ might facilitate the P 3a potential.

Objective To discuss the CT features of mediastinal teratoma.Methods 35 patients with mediastinal teratoma confirmed by clinical and pathologic data were retrospectively analyzed.Results Most mediastinal teratomas(97.1%) were localized in the middle or upper area of anterior mediastinum.Mediastinal teratoma included cystic teratoma(60.0%) and solid teratoma(40.0%).All kinds of tissues could be found in the tumors.CT features of cystic teratoma(n=21) were the cystic mass with fluid density,most of them(n=19) had the characteristics of "obviouswalled cysts".CT features of solid teratoma(n=14) were the soft-tissue mass with mixed densities.CT features of malignant teratoma(n=5) were that the layer of fatty tissue between the tumor and the surrounding structures disappeared,and that the wall of neighbour vessels were mostly or all surrounded by the tumor.Mediastinal teratoma could cause pleural offusion(n=6) and pericardial offusion(n=12).Conclusion Mediastinal teratomas have obvious CT imaging features.CT has very important value in the diagnosis and differential diagnosis of mediastinal teratoma.

Objective To assess the clinical value of taken out embryo by hysteroscopy in treatment of caesarean scar pregnancy. Methods 20 cases of caesarean scar pregnancy from May 2014 to April 2015 were treated with hysteroscopy. Results All the 20 cases were treated by hysteroscopy successfully, none of them suffered from conver-sion to laparotomy, perforation of uterus and heavy vaginal bleeding. Conclusions The operation of taken out embryo by hysteroscopy is effective operation in treating caesarean scar pregnancy with mini-trauma, few distress, and less cost.

OBJECTIVE To observe the clinical therapeutic effect of levofloxacin combined with cefoperazone-sulbactam on pulmonary infection caused by multidrug-resistant(MDR) bacillus infection.METHODS Eighty five patients with pulmonary infection caused by MDR bacillus infection were randomly divided into treatment group and control group,combined levofloxacin and cefoperazone-sulbactam were used in 45 patients of treatment group,ceftriaxone sodium was used in 40 patients of control group,their therapeutic effect was observed 7 days later.RESULTS Thirty four patients of treatment group were cured,7 patients with excellence,3 patients with improvement and only 1 patient was invalid.The total effective rate was 91%.Clinical manifestation such as cough,expectoration,and dyspnea had obviously improved.Sputum culture darkening rate was high.CONCLUSIONS Combined therapy of levofloxacin and cefoperazone-sulbactam has definite therapeutic effect on pulmonary infection caused by MDR bacillus infection.

Great progress has been made on vaccine research for schistosomiasis,including those on immune mec-hanism and Schistosoma genome which have made active effect to vaccine development.This paper reviews the progress on the candidate vaccine antigens including protein vaccine,DNA vaccine and multivalent vaccine against Schistosoma japonicum.

0.05). Conclusion Both CD54 and LRP expression have negative correlation with the effective rate of short-term therapeutic effects, therefore can be taken as indexes for prognostic evaluation for patients with non-small cell lung cancer.

Objective To analyze the relationship between renal function impairement and obesity in patients with primary hypertension.Methods One hundred and twenty-eight primary hypertension patients with renal function impairement admitted to our hospital from January 2012 to December 2015 were divided into obesity group (n=68) and control group (n=60) according to the Asian obesity diagnosis criteria established by the International Diabetes Federation.Relationship of serum urea nitrogen (BUN),creatinine,cystatin C (Cys-C),urinary N-acetyl beta-D glucosaminidase (NAG),urinary micro albumin levels and BMI with renal function impairment in primary hypertension patients was analyzed by multivariate linear stepwise regression analysis.Results The BMI,serum levels of urinary NAG,Cys-C,BUN,and creatinine were significantly higher in obesity group than in control group (31.70±1.80 kg/m2 vs 23.95±2.00 kg/m2,19.34±1.40 U/L vs 14.92±1.31 U/L,0.69±0.06 mg/L vs 0.47±0.05 mg/L,11.50±2.90 mmol/L vs 8.60±1.90 mmol/L,159.50±10.40 μmol/L vs 148.90±10.70 μmol/L,P＜0.05).The incidence of urinary micro albumin was significantly higher in obesity group than in control group (79.4％ vs 46.7 ％,P＜ 0.01).Blood pressure,pulse pressure difference,BMI,fasting blood glucose,serum levels of ereatinine,urinary NAG,Cys-C,BUN and urinary micro albumin were the risk factors for renal function impairement in primary hypertension patients (P＜0.05,P＜0.01).Conclusion Renal function impairement is related with obesity in primary hypertension patients.

Objective To study the curative efficacy of mometasone furoate aqueous nasal spray combined with loratadine in the treatment of pediatric allergic rhinitis, and its effects on IL-10, IL-17 in serum.Methods 126 patients of pediatric allergic rhinitis who were admitted in our hospital from May 2011 to September 2013 were selected as research objects and randomly divided into treatment group and control group, 63 patients in each group.The control group were treated with loratadine, while the treatment group were treated with mometasone furoate aqueous nasal spray in combination with loratadine.The curative efficacy, scores of clinical symptoms and nasal examination, curing time, medication time and serum IL-10, IL-17 levels were compared between the two groups.Results The total therapeutic efficacy ratio in the treatment group was 98.41%, which was statistically higher than that of 80.95% in the control group (P<0.05).5 weeks after the treatment, scores of sneezing, runny nose, nasal congestion, nasal itching, eye itching and nasal examination in the treatment group were statistically lower than those in the control group (P<0.05).The curing time and medication time in the observation group were statistically shorter than those in the control group ( P <0.05 ) .The inflammatory factors, in comparison with the control group after treatment, the treatment group had statistically higher level of serum IL-10 and lower level of serum IL-17 ( P <0.05 ) . Conclusion Mometasone furoate aqueous nasal spray in combination with loratadine is effective for pediatric allergic rhinitis with a high therapeutic efficacy ratio.And it could significantly improve clinical symptoms, shorten treatment time, increase level of IL-10 and reduce level of IL-17.
