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.

Berberine is a taste of traditional Chinese medicine.With the progress of research on pharmacology and mechanism of drug action of extensive research,the new mechanism of berberine was revealed through a series of clinical trials,the clinical indications continue to expand,and berberine has a therapeutic effect in digestive and endocrine system disease.The current study confirmed that berberine not only has the broad-spectrum antibacterial activity,but also plays a strong anti-inflammatory and immune regulatory role,which makes more and more research began to concern its application value in the diseases of respiratory system.The strong anti-inflammatory effect of berberine cau effectively relieve the airway inflammation of patients who are suffering from chronic obstructive pulmonary,and the broad-spectrum antibacterial effect brought hope for the treatment of tuberculosis and pneumonia.The subsequent animal and clinical studies have confirmed that berberine can effectively improve the symptoms of respiratory system diseases,and play a role in the treatment.

Antigen challenge of sensitized isolated guinea-pig mesentery perfused under constant pressure resulted in a significant flow reduction which was induced by the release of leukotrienes bioassayed on guinea-pig ileum. 3 min after challenge, the mescnteric perfusion rate dropped to a minimum of 32?12% ( P

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 study the CT features and the diagnostic value of ovarian tumors in adolescent.Methods CT findings of ovarian tumors in adolescent proved by operation and pathology in 29 cases were retrospectively analyzed and compared with surgical and pathological results.Results Of 29 case , there were 18 cases benign tumors and 11 cases malignant tumors . Among them,there were ovary germ cell tumors 19 cases ( 65.5% ) , epithelial tumors 5 cases ( 17.2% ) , nonneoplastic cystic 3 cases(10.3%) and sex cord stromal tumors 2 cases (7%). CT manifestations included 17 cystic mass ,6 cystic-solid mass and 10 solid mass,in which benign tumors more seen cystic mass and solid in malignant. Torsion of ovarian tumors was found in 5 cases, haemorrhage in cystic mass was detected in 6 cases.Conclusion CT is a valuable imaging modality in the diagnosis of ovarian tumors in adolescent.

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 investigate the clinical effect of ginger-partitioned moxibustion at Zigong (EX-CA 1) for primary dysmenorrhea. Methods: A total of 112 patients with primary dysmenorrhea were randomized into an observation group and a control group according to their visiting sequence, 56 cases in each group. Patients in the observation group received ginger-partitioned moxibustion at Zigong (EX-CA 1), while patients in the control group received oral intake of analgesic. For both groups, treatment started 1 week before menstruation and lasted for 3 menstrual cycles, continued by a 3-month follow-up visit, then the clinical efficacy was evaluated. Results: By the end of treatment, symptom score in the observation group was lower than that in the control group, showing a statistical significance (P<0.05). After 3 months of treatment, the value of prostaglandin F2a (PGF2α), systolic-to-diastolic peak velocity ratio (S/D), resistance index (RI) and pulsatility index (PI) in the observation group were significantly higher than those in the control group, showing statistical significances (all P<0.01).The recovery rate in the observation group was higher than that in the control group, showing a statistical significance (P<0.05). Conclusion: Ginger-partitioned moxibustion at Zigong (EX-CA 1) for primary dysmenorrhea is a combination of the merits of warming function of moxibustion, dissipating function of ginger and stimulation of acupoint, and is better than oral intake of analgesic.

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.
