1.Study on interactive courseware of abnormal gait analysis
Chinese Journal of Tissue Engineering Research 2007;0(05):-
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 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.
3.Study on space distribution of rabbit P3a potential
Chinese Journal of Tissue Engineering Research 2001;5(10):47-48
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.
4.Research progress of pancreatic protein tumor markers
International Journal of Surgery 2012;39(8):546-549
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.
5.Research progress and mechanism of berberine in respiratory diseases
Journal of Chinese Physician 2016;18(12):1911-1913
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.
6.Expression of the antigen detected by the monoclonal antibody AU_(14-1) in human cervical lesions
Chinese Journal of Pathophysiology 1986;0(03):-
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.
7.Preliminary studies on antigenic modulation induced by monoclonal antibody
Chinese Journal of Pathophysiology 1986;0(03):-
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.
