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.

Pancreatic cancer is a commonly malignant gastrointestinal tumor with an obviously increasing incidence all over the world.Those patients without specific symptoms at early stage had mostly lost the opportunity of surgical therapy when pancreatic cancer was detected at advanced stage,and their prognosis is poor.Therefore,it is rather crucial to improve the early diagnosis of pancreatic cancer.Tumor marker is a considerable tool for early tumor detection and screening.It will help to improve the diagnostic rate of early pancreatic cancer and promote the prognosis of pancreatic cancer if we could find out tumor markers and screen one or a group of pancreatic cancer tumor markers.

Objective To explore the role of Th17/IL-17 in the pathogenesis of asthma in children.Methods Thirty asthma children (asthma group) and 20 healthy volunteers (control group) were selected as our subjects.Percentage of Th17 cell in peripheral blood mononuclear cell (PBMC) of asthma children was detected by flow cytometry,the level of IL-17 and IgE in plasma were examined by enzyme linked immunosorbent assay.Results Proportion of Th17 cells in PBMC of children in asthma group was (1.83 ± 1.01) ％,significantly higher than that in control group ((1.02 ± 0.49) ％ ; t =3.896 ; P ＜ 0.01).The IL-17 level in control group was (19.11 ± 3.23) ng/L,significant lower than that in asthma group ((34.23 ± 4.88) ng/L;t =6.261 ;P ＜ 0.01)).The Ig E level in asthma group was (399.4 ± 45.1) ng/L,significantly higher than in control group((58.2 ± 19.7) ng/L;t =7.244,P ＜0.01).The level of IL-17 in plasma had a postive relationship with the proportion of Th17 cells(r =0.882,P ＜0.01),but not relationship was seen with the level of IgE (r =0.375,P ＜ 0.05).Conclusion Th1 7 cell is associated with asthma development of children,and the reason may due to probably aggravating asthma condition through increasing inflammation secreting IL-17.

Objective To explore the viral etiology of acute respiratory tract infections in Nanping area .Methods A total of 3 572 patients ,suffered from acute respiratory tract infections from December 2012 to December 2014 were enrolled in the study .Sev‐en common respiratory viruses were detected by direct immunofluorescence assay ,including influenza A virus(IA) ,influenza B virus (IB) ,adenovirus (ADV) ,respiratory syncytial virus (RSV) ,arainfluenza type Ⅰ (P1) ,arainfluenza type Ⅱ (P2) ,arainfluenza typeⅢ (P3) .Results In total 3 572 samples ,509 samples were virus positive (14 .25% ) .Among them ,507 positive samples were single virus infections and 7 positive samples were double virus infections .RSV infection(9 .38% ) ,P3 infection(2 .32% ) and IA infection (1 .09% ) rates were the top three .Conclusion RSV was the main viral pathogen among 7 common respiratory viruses with obvious seasonal periodicity .Children′s immunity is low and need to prevent respiratory viral infections .

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.

In this article, monoclonal antibody to mouse uterine cervical carcinoma (U_(14)), AU_(14-1), was used for immunohistochemical analysis of premalignant and malignant lesions of the cervix to investigate the incidence and significance of the expression of the antigen detected by AU_(14-1) in human cervical lesions. Peroxidase-antiperoxidase (PAP) staining was performed on formalin-fixed, paraffin-embedded biopsy specimens. It was reported that positive staining with AU_(14-1) was detected in 20 of the 20 squamous cell carcinomas, 13 of the 13 adenocarcinomas, 15 of the 21 carcinomas in situ, 2 of the 24 anaplasia, and 2 of the 20 chronic cervicitis. It is suggested that the expression of the U_(14) antigen may be related to malignant transformation in the cervix.

The TD。 of mouse uterine cervical carcinoma (U_(14)) were inoculated subcutaneously in syngenic mice. After that experimental mice were administered diverse doses of monoclonal anti-U_(14) antibody (AU_(14-1)). It was found that within a 267 day interval after the tumor cell inoculations, all control animals were tumor free with tumor free survival, but 86% (6/7)and 88% (7/8)of experimental mice that had been treated with high dose AU_(14-1) showed progressive tumor growth at the inoculation site and died of systemic tumor disease. These results indicate immune enhancement of AU_(14-1) on U_(14) cells. AU_(14-1) was used to study the response of U_(14) cells to specific anti (?)dy in vitro. The results demonstrate that AU_(14-1) induces antigenic modulation of U_(14) cells, which is shown to be a loss of AU_(14-1) antibody and U_(14) antigen from the surface membrane of these cells as determined by indirect membrane immunofluorescence assay. This suggested that antigenic modulation may be proposed as a mechanism by which cervical cancer cells escape monoclonal antibody therapy.

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
