3.Mathematical model and applicable prescription of ankle-foot orthosis and its early application in analysis of hemiplegic gait of stroke patients
Chinese Journal of Tissue Engineering Research 2008;12(22):4389-4392
With the development of the Multi-Rigid-Body system dynamics theory and computer technology, computer aided design and manufacturing of orthosis have already matured, mathematical mechanical model of human body and orthosis can be established using this new technology, and simulation calculation can be used to determine the orthosis prescription, predict the efficacy and effectiveness of rehabilitation. Early application of ankle-foot orthosis plays an important role in restoration of brain function in stroke patients, resumption of hemiplegic gait and abnormal gait correction. In clinical orthosis prescription, establishment of corresponding mathematical model and speculation of ankle-foot function changes, as well as the effect and mechanism of resumption of brain function in post-stroke patients, have a positive impact on the analysts of hemiplegic gait, orthosis design and gait resumption.
4.Preliminary Study on Anticyclophilin A Auto-Antibodies in Sera of Patients with Psoriasis
Chinese Journal of Dermatology 2001;34(2):93-94
Objective To determine the level of anticyclophilin A auto-antibodies (ACA) in sera of patients with psoriasis. Methods Cyclophilin A (CyPA) was extracted and purified from bovine thymus. The level of anticyclophilin A auto-antibodies (ACA) was detected by enzyme-linked immunosorbent assay (ELISA) and immunoblotting test (IBT) in sera of patients with psoriasis. Results It was shown that the level of ACA was significantly higher in the sera of patients with psoriasis than those in control group (IBT:P<0.01,ELISA:P< 0.01). ACA was found to be positive in 41.3% of the patients by ELISA. In psoriatic group, the serum level of ACA was higher during the progressive stage than that in the stationary stage, however, no significant difference was observed (IBT:P>0.05,ELISA:P >0.05). Conclusion The results suggest that there is autoimmunological mechanism in the pathogenesis of psoriasis.
5.Clinical Experience of Professor Shen Hong for Treating Chronic Atrophic Gastritis
Journal of Zhejiang Chinese Medical University 2015;(5):345-347
Objective] To summarize professor Shen Hong's clinical experience in treating chronic atrophic gastritis. [Method] By following the teacher clinic and sorting out the related medical materials, the author summarizes professor Shen Hong's academic experience of treatment of chronic atrophic gastritis, and for proven cases. [Result] Professor Shen Hong thinks that the essence of pathogenesis is the weakness of the spleen and stomach. Qi stagnation, damp stagnation and blood stasis are common pathological factors. The characteristic of the disease is deficiency in origin and excess in superficiality. The location of disease is in stomach, relating to liver and spleen. The principle of treatment should be strengthening the spleen and stomach. It is also very important to treat accompanying symptoms and balance property of Chinese medicines. Prof. Shen emphasizes the combination of disease and syndrome differentiation and the integration of TCM and western medicine. He attaches much weight to diet and psychotherapy. The medication is concise and the prescription changes flexibly with the permitted addition and subtraction. The clinical curative effect is satisfactory. [Conclusion] Professor Shen Hong 's experience is effective and worthy of inheritance and promotion.
6.Analysis of the Use of Narcotic Analgetics in Our Hospital During 2005~2007
China Pharmacy 2005;0(20):-
OBJECTIVE: To evaluate the utilization and its trend of narcotic analgetics in this hospital.METHODS: The use of narcotic analgetics during the period 2005-2007 in our hospital was analyzed retrospectively.RESULTS: The consumption quantity of narcotic analgetics in our hospital increased year-on-year,much as in the consumption of morphine preparations,with oral morphine preparations dominating the 3 first places over the 3 years,however,the increase of pethidine was slowed down in consumption quantity.CONCLUSION: The use of narcotic analgetics in our hospital is rational on the whole,but measures should be taken to tighten the control on the use of narcotic analgetics.

8. Expression of plasminogen activator and plasminogen activator inhibitor in ovarian of patients with polycystic ovary syndrome
Academic Journal of Second Military Medical University 2010;31(12):1309-1313
Objective: To investigate the association of polycystic ovary syndrome (PCOS) with plasminogen activator (tissue-type plasminogen activator [t-PA], urokinase-type plasminogen activator [u-PA]) and plasminogen activator inhibitor-1 (PAI-1). Methods: The ovary tissues of 30 PCOS patients who were treated in our hospital from Dec. 2007 to Oct. 2008 and 20 healthy controls were collected. The expression of t-PA, u-PA, and PAI-1 was examined by immunohistochemistry method. Results: In PCOS group, the positive rates of u-PA, t-PA in the granulosa cells were 20.00% and 26.67%, and in the theca cells were 33.33% and 20.00%, respectively; in the control group, the positive rates of u-PA, t-PA in the granulosa cells were 65.00% and 75.00%, in the theca cells were 75.00% and 50.00%, respectively; and there were significant differences between the two groups (P<0.05). In PCOS group, the positive rate of PAI-1 was 56.67% in the theca cells and 63.33% in interstitial cells; in the control group, the positive rates of PAI-1 were 10.00% both in the theca cells and the interstitial cells; and there were significant differences between the two groups (P<0.05). Conclusion: The disruption of plasminogen activator system may be involved in ovulation disorder of PCOS.
