0.05). Conclusion The results suggest that there is autoimmunological mechani sm in the pathogenesis of psoriasis.

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.

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.

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.

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.

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.

●METHODS: Totally 60 patients with cataract in our hospital from November 2011 to September 2013 were included as the observation group, and 60 patients with eye traumas were as the control group. The serum, aqueous humor and tear lL - 2, slL - 2, NO, TAC, and SOD of two groups were detected and compared, and the detection levels of patients with different stages were compared.
●RESULTS: The serum, aqueous humor and tear lL-2, TAC, and SOD of observation group were all lower than those of control group, the slL-2 and NO were all higher than those of control group. The serum, aqueous humor and tear detection levels of patients at different stages had obvious differences, and the aqueous humor lL - 2 were lower than those of serum and tear, the slL-2 were higher than those of serum and tear, with statistically significant differences.
●CONCLUSlON: The change of serum, aqueous humor and tear lL-2, slL-2, NO, TAC, and SOD of patients are all great, and the influence of the stages for those indexes are great too, the inflammatory response state of aqueous humor are more obvious.

Objective To develop a method for the determination of the dynamic parameters of interaction between methotrexate(MTX)enantiomer and dihydrofolate reductase(DHFR).Methods An affinity capillary electrophoresis(ACE)method was adopted.Using bare fused-silica capillary,the electrophoresis buffer was 50 mmoL/L sodium tetraborate with 0.2%Brij-35,pH 9.50.The temperature of separation was controlled at 25℃ and a voltage of 25 kV was applied.The separation of the reaction mixture was performed at a wavelength of 254 nm.The difference of peak areas about the product was used to calculate the inhibitory rate and IC50 values.Results We establish the detection method for the dynamic parameters of interaction between MTX enantioner and DHFR.The separation of the reaction mixture could be achieved within 30 min.The IC50 value of D-(-)-MTX and L-(+)-MTX were 3.17×10-7 and 2.48×10-8mol/L,respective.The IC50 value of the D-(-)-MTX was 31.67×10-8mol/L,the L-(+)-MTX was2.48×10-8mol/L.The IC50 value of the D-(-)-MTX was about 13 times higher than that of the L-(+)-MTX.Conclusions ACE is a rapid.simple and accurate method that can be used to monitor DHFRdynamic reaction.The IC50 values of MTX enantiomer were quite different.The result first indicated that reaction between MTX enantiomer and DHFR had three-dimensional selection.
