BACKGROUND: Uncoupling of major histocompatibility complex (MHC) is the main cause for transplantation rejection, and it is the best way to prevent transplantation rejection by induce immunological tolerance of the recipient to the donor organ. Self-tolerant T cells can be obtained by negative selection in thymus, whether the intrathymic injection of allogenic antigen can get the immunological tolerance to the antigen?OBJECTIVE: To observe the effects of intrathymic injection of allogenic antigen on inducing immunological tolerance in nerve transplantation.DESIGN: A comparative observation.SETTINGS: Department of Immunology, Harbin Medical University; Department of Orthopaedics, Fourth Clinical Hospital of Harbin Medical University.MATERIALS: Thirty donor C57BL/6 mice (H-2b), male, aged from 6-8 weeks, weighing 18-22 g, were purchased from the Veterinarian Institute of Heilongjiang Province; While 60 recipient Balb/c mice (H-2b) female, aged from 6-8 weeks, weighing 18-22 g, from Beijing Experimental Animal Center. MHC (H-2b) antigen was prepared by the Department of Immunology, Harbin Medical University, and the concentration of protein was 4.4 g/L.METHODS: The experiments were carried out in the Department of Immunology, Harbin Medical University from June to November 2002. The recipient Balb/c mice were randomly divided into four groups: intrathymic injection group, syngenic transplantation group, allogenic transplantation group and immunosuppressant drug group. MHC (H-2b) antigen was extracted from splenic cells of donor C57BL/6 mice and injected intrathymically into recipient Balb/c mice (H-2d). Two weeks later, the sciatic nerve was transplanted to the recipient mice. Mixed lymphocyte reaction and delayed-type hypersensitivity (DTH) were detected at 3 weeks after transplantation.MAIN OUTCOME MEASURES:The differences of mixed lymphocyte reaction and DTH were compared among the groups.RESULTS: All the 30 donor C25BL/6 mice (H-2b) and 60 recipient Balb/c mice (H-2d) were involved in the analysis of results.①Results of mixed lymphocyte reaction: The cell proliferations in the syngenic transplantation group and intrathymic injection group were obviously lower than that in the allogenic transplantation group [(546.1±75.1), (2 668.3±533.8), (3 101.3±429.1), (4 312.3±534.1) minutes-1, P<0.05].②Results of DTH: The thicknesses difference between two pads in the syngenic transplantation group and intrathymic injection group were obviously lower than that in the allogenic transplantation group [(41.1±3.7), (72.1±5.1), (57.6±11.3), (86.2±13.2)μm, P<0.05].CONCLUSION:The intrathymic injection of donor H-2b antigen could induce immunological tolerance of nerve transplantation.

Case-based reasoning is a method of reasoning from experience to solve current problems in the field of cognitive science, which has the advantages of easy acquisition of knowledge, simple operation steps, and the ability to improve the efficiency of reasoning with the growth of experience. Formula-syndrome differentiation is a method of differentiation and treatment based on the scope of the adapted disease, disease mechanism, therapeutic methods, and contraindications of the formula. Analysed from the perspectives of concept, applicable field, and implementation steps, it is believed that the concept of formula-syndrome differentiation belongs to the scope of case-based reasoning, the clinical diagnosis and treatment of traditional Chinese medicine belongs to the applicable field of case-based reasoning, and the steps of formula-syndrome differentiation are consistent with the process of case-based reasoning. Based on the characteristics of case-based reasoning, we analyse the advantages, limitations and problems to be noted in the process of formula-syndrome differentiation, and put forward four strategies to improve the ability of formula-syndrome differentiation, including accumulating experience on formulas and syndromes, cultivating the ability to grasp the main symptoms, accumulating a rule base to improve the ability to modify formulas according to the symptoms, and improving the ability to assess the effect of treatment plans and obtain corresponding feedback, with a view to promoting the clinical application of formula-syndrome differentiation.

Objective:To compare the clinical effects of platelet-rich plasma (PRP) and sodium hyaluronate on rotator cuff injury.Methods:From February 2022 to December 2022, 226 patients with rotator cuff injury caused by military training were treated at Department of Orthopaedics, Jinling Hospital, School of Medicine, Nanjing University. They were all male, aged (24.5±3.7) years, and their time from injury to treatment was (4.6±2.2) months. They were divided into 2 even groups according to different treatments: an observation group of 113 cases into whose subacromial space PRP was injected, and a control group of 113 cases into whose subacromial space sodium hyaluronate was injected. In both groups, the injection was performed once a week for consecutive 3 weeks. The 2 groups were compared in terms of visual analogue scale (VAS) and Constant-Murley shoulder function scale (CMS) before treatment and 4 and 8 weeks after treatment, and the levels of TNF- α and IL-6 in the shoulder synovial fluid before treatment and 8 weeks after treatment. Results:There was no statistical difference between the 2 groups in general clinical data before treatment, indicating comparability ( P>0.05). At 4 and 8 weeks after treatment, compared with the pre-treatment values, the VAS scores were significantly decreased and the Constant-Murley scores significantly increased in both groups ( P<0.001). At 4 and 8 weeks after treatment, the VAS scores in the observation group (3.1±0.9 and 1.5±0.5) were significantly lower than those in the control group (3.7±0.8 and 2.3±0.6) while the Constant-Murley scores in the observation group (58.6±4.5 and 72.2±4.1) significantly higher than those in the control group (55.2±5.3 and 67.8±5.0) ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the 2 groups were significantly lower than the levels before treatment ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the observation group [(2.9±0.9) μg/L and (0.8±0.2) μg/L] were significantly lower than those in the control group [(4.0±0.4) μg/L and (1.1±0.4) μg/L] ( P<0.001). Conclusion:Injection of PRP or sodium hyaluronate can relieve pain and improve shoulder function obviously in patients with rotator cuff injury, but PRP is superior to sodium hyaluronate in the treatment of rotator cuff injury.
