Objective: To explore antitumor responses induced by recombinant vaccinia viruses expressing a p53 antigenic peptide (rVV-p53M) and enhanced effect of recombinant vaccinia viruses expressing costimulatory molecule B7 (rVVB7). Methods: A 135 Cys to Tyr point mutation p53-transduced P815 mastocytoma (P815-mp53) was used as an experimental tumor and the p53 protein as the model of tumor associated antigen. rVV-p53M and rVV-B7 were used as vaccine to test their induction of CTL and antitumor immunity. Results: Immunization of BABL/c mice with rVV-p53M could elicit specific CTLs, which could specifically lyse P815-mp53 cells. Immunization of mice with rVV-p53M could survive a part of mice challenged with 1×106 P815-mp53. Treatment with rVV-p53M could significantly prolong the survival oftumor-bearing mice. Admixture at 1:1 ratio of rVV-p53 M and rVV-B7 could enhance antitumor responses induced by rVV-p53M. Conclusion: Immunization with recombinant vaceinia virus expressing antigenic peptide is a useful alternative to peptide-based vaccine. Costimulatory molecule B7 can enhance antigenic peptide to induce antitumor responses.

In this paper, through a systematic review of literatures on pectoral qi theory, we summarized the defini-tion of pectoral qi, physiological function, deficiency-excess changes, clinical manifestations of pectoral qi deficiency and modern research progress of pectoral qi theory, in order to deepen the understanding of pectoral qi connotation. The connotations of pectoral qi have four major kinds of views. The pectoral qi is a combination of the natural fresh air inhaled by the lungs and the foodstuff essence-qi transformed by the spleen-stomach accumulated in the thorax. The substance of pectoral qi is heart-lung yang qi. Pectoral qi is the special title of acquired essences in the thorax. Pectoral qi accumulated in the thorax is the beating-qi beneath the left breast. Its physiological function includes flowing through the respiratory tract to promote the respiration movement of the lungs, permeating the heart and ves-sels to promote circulation of qi and blood, comprehensively regulating of the heart and lungs, controlling all qi and zang-fu, accumulating body fluids, resisting external evils, controlling mental activities, maintaining mental state healthy and vigorousness, controlling vision, hearing, sound, color, smell and movement, converging primordial qi to maintain the vigor and vitality. Disorders of pectoral qi are mainly manifested as deficiency or excess. Deficiency is mainly manifested in pectoral qi insufficiency, or pectoral qi sinking. Excess is mainly manifested in pectoral qi ob-struction, or pectoral qi counterflow. The common clinical manifestations of pectoral qi insufficiency include short-ness of breath and panting on exertion. The concomitant symptoms are pale or dim complexion, lassitude, lack of strength, shortage of breath and disinclination to talk, insomnia, dizziness, spontaneous sweating, emaciation, darkish tongue with thin and white fur, sunken thin or weak pulse. And it commonly superimposed with failing to circulation qi-blood of heart and lungs as chest distress, chest pain, palpitations, cyanosis, cough, expectoration, and hard stool. Spleen transportation and transformation dysfunction were manifested as poor appetite, loose stool, and abdominal dis-tension. Impairment of qi transformation due to yang deficiency is manifested as cold limbs, aversion to cold, edema, urination difficulty, and dry mouth. In addition, diseases which are treated with pectoral qi are give priority to the heart-lung diseases, and then gradually extend to diseases of other systems. At the same time, there are many reports on using pectoral qi theory in disease treatment. The essence of pectoral qi is also discussed from the perspective of modern medicine. Generally speaking, pectoral qi theory has been put forward early; however, the systematic study is difficult to meet the needs of clinical diagnosis and treatment. There are many problems which remain to be further studied and solved.

Pulmonary fibrosis is a common respiratory disease in the clinic. Until now, the pathogenesis is still un-clear. Using clotting mechanism as the starting point, this article mainly explored abnormal changes of the coagula-tion - fibrinolysis system in the development of pulmonary fibrosis. The effective treatment through the activation of blood circulation to remove stasis in traditional Chinese medicine (TCM) point of view was also observed on the man-agement of interstitial pulmonary fibrosis. It considered that to carry out the anticoagulant therapy for abnormal coag-ulation, which may become a new target for clinical treatment of interstitial lung diseases. It provided new ideas and theoretical support for clinical treatment of pulmonary interstitial fibrosis.

Objective:
To explore the relationship between aggression and category perception of angry expression in reform school students under social exclusion, so as to provide reference for the reform school students mental health promotion.
Methods:
In May 2023, 144 students were randomly selected from a reform school in Guizhou Province, and were divided into high and low aggression groups(77 and 67 students) by Aggression Questionnaire. Cyberball game was used to induce social exclusion and acceptance, subjects were divided into high aggressive exclusion group ( n =42), high aggressive acceptance group ( n =35), low aggressive exclusion group ( n =37) and low aggressive acceptance group ( n =30). All the participants completed the discrimination and identification tasks of category perception paradigm, and the relationship between aggression and category perception of angry expression of reform school students under social exclusion was analyzed by using category turning point, identification curve and analysis of variance.
Results:
The total score of aggression(97.34±8.00) and four dimensions (physical aggression: 29.75± 4.61, verbal aggression:17.19±2.58, anger:22.29±3.66, hostility:28.10±3.54) in the high aggression group were higher than those in the low aggression group(74.10±9.02,21.09±4.98,14.30±2.66,17.16±3.83,21.55±3.88), and the differences were statistically significant ( t =16.38, 10.85, 6.62, 8.20, 10.59, P <0.01). For identifying the turning point of the fear anger continuum, the social exclusion group(2.58±0.07)was significantly smaller than the social acceptance group(2.79±0.07)( F =4.85, η 2=0.07, P < 0.05 ), and the social exclusion group had a tendency to shift the category boundary to the fear side. For identifying the slope at the angry happiness continuum category boundary curve, the high aggression group (0.63±0.03) was significantly higher than the low aggression group (0.53±0.03)( F =5.38, η 2=0.08, P <0.05). In the fear anger continuum,the high aggression group[(694.86± 78.29 )ms] reacted more quickly than the low aggression group[(660.70±79.86)ms]( F =5.08, η 2=0.05, P <0.05) In the angry happiness continuum, there was no statistical significance of social exclusion and aggression( P >0.05).
Conclusions
The suggests that social exclusion can lead to hostility attribution bias in individuals, while aggression can make individuals more sensitive to angry expression. The mechanisms by which social exclusion and aggression affect expression category perception are independent rather than interactive. The society should give tolerance and acceptance to reform school students, reduce exclusion and discrimination, and the reform education department should correct the aggressive behavior of reform school students and promote their mental health.
