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.
2.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.

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.
4.An analysis of clinical characteristics of autoimmune pancreatitis
Chinese Journal of Internal Medicine 2010;49(11):943-946
Objective To increase the appreciation of manifestations in autoimmune pancreatitis (AIP) and to decrease misdiagnosis rate by investigating the clinical characteristics of AIP. Methods Clinical data were collected and laboratory ,imaging and histopathology were analyzed from the Chinese PLA General Hospital from 1995 to 2009. Patients with AIP were included in the study. Results Eight patients (male 6, female 2) aged 35-69 (52.4 ±9.4) years were diagnosed as AIP from 2006 to 2009. The main clinical manifestations include intermittent jaundice in 6 cases (6/8), abdominal pain in 5 cases (5/8),weight loss in 4 cases (4/8), and accompanied with other diseases of immune system in 4 cases (4/8).The imaging showed head of pancreas enlargement in 3 cases (3/8) and whole pancreas enlargement in 5 cases (5/8). There is a "banana-peel like" ring around the pancreas and irregular stenosis of pancreatic duct. Massive lymphocytes and plasma cells infiltration and parenchymal fibrosis were shown in pancreatic tissues, bile duct,salivary gland and liver in pathology. Clinical manifestations, laboratory examinations and images in 7 cases (7/8) were improved after treatment with prednisone. Twenty-two of them were misdiagnosed as pancreatic or biliary carcinoma and 21 were performed laparotomy in the period of 1995-2005 ( 23 cases). After 2006, however, the misdiagnosis rate significantly decreased from 95.7% ( 22/23 ) to 0. Conclusions AIP seems to be a systemic autoimmune disease rather than an isolated disorder,markedly overlapping with other autoimmune diseases. Definitive diagnosis can be improved by the detection of immune parameters and pathological examination.
5.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.
6. Self-designed adjustable titanium screw in treatment of unilateral vocal cord paralysis: An observation of curative effects
Academic Journal of Second Military Medical University 2010;30(10):1145-1149
Objective: To observe the curative effects of self-designed adjustable titanium screw in treatment of unilateral vocal cord paralysis in dogs. Methods: We designed and prepared an adjustable titanium screw. The beagle dogs were divided into an experimental group and a control group (n = 3) at random. Animals in the experimental group had their left recurrent laryngeal nerve resected and received implantation of adjustable titanium screw. The left arytenoid cartilage was adjusted to allow the left vocal cord in the middle, so as to achieve glottis closure when making a sound. The dogs in the control group only received recurrent laryngeal nerve resection. Observation with electron fibrolaryngoscope and CT was done immediately, 1, 2, and 4 months after operation: electron fibrolaryngoscope was also used before operation. The curative effects and the prognoses of dogs were observed. Results: Four months after operation electron fibrolaryngoscope found that the adjustable screw in the experimental group could make the left arytenoid cartilage move inwardly, benefiting glottis closure and improving the voice quality. Animals in the control group had their left vocal cord located in the paramedina position, and there was cleft during glottis closure. CT image indicated that the adjustable screw was in a good position, and there was no breaking off. Local slight inflammation was seen in both groups 1, 2, and 4 moths after operation. Tntrinsic laryngeal muscle atrophy aggravated as time passing by. There was no severe inflammation around the implants or implants excretion. Conclusion: Our adjustable screw is easy to perform in surgical treatment of unilateral vocal cord paralysis; it can be adjusted during operation and the outcome can be observed in time. The short-time effect is confirmed and the method is worth popularizing.
