In a fusion of BABL/C murine spleen cells immunizated with human fetal thymocytes and P_3X_(3)Ag_(,3), myeloma cells, six monoclonal antibodies(McAb) were produced. They were termed HIT_1. HIT_2. HIT_3. HIT_4.HIT_(6-1) and HIT_(6-2), respectively. The specificity of these McAbs were analysed by indirect immunofluorescence technique and FACS.Results showed that they reacted with 80~90%thymocytes,but hardly with peripheral blood mononuclear cells and spleen cells in adults,and nonreactive with red blood cells, granulocytes and platelets, According to their reaction with the tonsil cells, we can divide these six McAbs into three groups: Groupl including HIT_1, HIT_2, and HIT_(?) McAbs reacted approximately with 1/3 tonsil cells; basically GroupⅡ including HIT_(6-1) and HIT_(6-2) McAbs gave negative reaction with tonsil cells; GroupⅢ McAb HIT_4 reacted with 15% tonsil cells, which suggested these were a heterogeneous group McAbs with different specificities. In comparision with OKT series of McAbs in thymus, peripheral blood and tonsil, HIT_(1-3) are similar to OKT_(10) and,HTT6-l and HIT_(6-2) are just like OKT_6,but HIT_4 seems to be a new McAb different frOm HIT_(1-3) and HIT_(6-1) HII_(6-2). The competitive binding assay showed that HIT_(6-1) and HIT_(6-2) labeled with FITC can be inhibited by unlabeled HIT_(6-1) and HIT_(6-2) each other and can also be blocked by OKT_6, suggesting further these antibodies recognized a same epitope on thymocytes. Cross reaction were also demonstrated on HIT_1, and HIT_2 but not on HIT_3, suggesting HIT_1 and HIT_2 recognized the same determinant and HIT_3 recognized another. So six antibodies are McAbs against T cell differentiation antigens.They are useful for research the differentiation of T cells and the classification of malignant lymphadenosis diseases.

Objective:To analyze the satisfaction of elderly outpatient experience, based on a satisfaction questionnaire survey of outpatients in public hospitals, for references to improve the medical experience of elderly patients.Methods:This study extracted the satisfaction survey questionnaires for outpatients in second level and above public hospitals nationwide from the National Health Commission′s satisfaction survey platform from 2019 to 2022. The questionnaire content included six dimensions: registration experience, doctor-patient communication, nurse-patient communication, environment and labeling, privacy protection, and medical staff response, as well as overall satisfaction. The satisfaction, relative satisfaction, and dissatisfaction rates of elderly outpatients were analyzed using standardized assignment of question options, etc; T-test was used for inter group comparison.Results:A total of 10.095 7 million outpatient satisfaction questionnaires were included in this study, including 0.576 3 million questionnaires for elderly outpatients. From 2019 to 2022, the overall satisfaction of outpatients had been increasing year by year, and the overall satisfaction scores of elderly patients were significantly higher than that of non-elderly patients( P<0.01). The satisfaction scores of elderly patients in the nurse communication dimension(86.55 to 91.03 points) and relative satisfaction(1.000) were the higher in each year, while the satisfaction scores in the environment and identification dimension(81.05 to 86.03 points) and relative satisfaction(0.935 to 0.955) were lower. In 2019 and 2022, elderly patients had higher dissatisfaction rates in the two dimensions of registration experience(2.26%, 1.91%) and doctor communication(0.80%, 0.53%). Conclusions:From 2019 to 2022, the overall satisfaction of elderly patients in secondary and above public hospitals in China was relatively higher with a steady increasing tendency. However, there was still room for further improvement in the environment and labeling, cultural construction, and registration experience for elderly patients.
