With the great stride forward of socialist progress, various medical treatment measures have also made a leap forward in development, providing a deeper guarantee for people's life safety. At the same time, the research field of nanotechnology has gradually developed in the medical field, which plays an important role in the development of medicine, and massage exercise rehabilitation training also provides convenience for patients' recuperation. The purpose of this study is to study the application of composite NanoBone transplantation in patients with limb replantation and the application of massage exercise rehabilitation training in patients with limb replantation. The methods used in this paper are: consulting the literature to understand the composite NanoBone transplantation technology and massage exercise rehabilitation training methods, interviewing the patients and attending doctors, and asking about the selection method of experiment and questionnaire used in the paper, so as to carry out the questionnaire survey. The treatment group and the control group were set up to analyze the results. The results showed that there were no significant differences in T lymphocyte subsets, serum complement, and circulating immune complex in the replantation of amputated limbs. Combined with the clinical manifestations and pathological results, early rejection occurred, and the body temperature of the patients increased after clinical treatment; The characteristics of massage are not practical, the course of treatment is short, the effect is fast, the clinical operation is simple, easy to grasp, and has high clinical application and promotion value. The final test results showed that: comparing the two groups of patients before treatment, the VAS scores were 23% and 21%, respectively, and the treatment group scores were 23% and 21%, respectively. After treatment, the VAS scores of the test group and the control group were 29 % and 27%, respectively. The treatment group scored 2% higher than the control group. From this, it can be concluded that massage is better than traditional massage, and massage exercise has great application prospects in clinical practice. [ABSTRACT FROM AUTHOR]

Immunohistochemical staining is a common technique to study tissue morphology and in situ protein expression. With the rise of immunotherapy, more and more markers in the tumor microenvironment have been discovered. In this paper, the multiplex immunofluorescence staining method was used to stain paraffin sections of 35 cases of gastric adenocarcinoma tissue and 35 cases of colorectal adenocarcinoma tissue and its adjacent tissue. The infiltration of CD8+ T cells and CD103+CD8+ T cells in the slices was detected by using the slice scanner to form the map and CaseViewer2.0 software analysis. The experimental results in this paper showed that compared with adjacent tissues, the infiltration degree of CD8+ T cells in gastric adenocarcinoma tissue was significantly lower (Z = 2.244 , P = 0.025 , P < 0.05), and the infiltration degree of cells was significantly lower (Z = 2.785 , P = 0.005 , P < 0.05). In gastric adenocarcinoma tissue, the infiltration of CD8+ T cells was correlated with the tumor diameter of gastric adenocarcinoma (P = 0.002). There was a statistically significant difference. The degree of CD103+CD8+ T cell infiltration was related to the survival of patients with gastric adenocarcinoma (P = 0.002) and the degree of tumor differentiation (P = 0.004). The infiltration of CD103+CD8+ T cells in gastric cancer tissue and colorectal cancer tissue is related to the survival of patients. CD103+CD8+ T cells are thought to play a role in the prognosis of gastric adenocarcinoma and colorectal adenocarcinoma. Experiments have shown that the more the CD103+CD8+ T cells, the better the prognosis of gastric adenocarcinoma and colorectal adenocarcinoma, so the prognosis of gastric adenocarcinoma and colorectal adenocarcinoma can be improved by increasing CD103+CD8+ T cells.

Umbilical cord blood (UCB) transplants (UCBTs) are becoming increasingly common in the treatment of a variety of hematologic and nonhematologic conditions. The T cells from UCB are naïve T cells, which have not yet been exposed to antigens and therefore do not contain T cells with specific immune functions against viruses. Cytomegalovirus (CMV) infections occur in more than 80% of patients after UCBT compared to other types of transplantation. Anti-CMV medications are currently restricted, with ganciclovir, foscarnet, and valganciclovir being the most common in China; however, with limited efficacy and considerable side effects, all these drugs are susceptible to viral resistance. In recent years, cytomegalovirus-specific T cells (CMVST) have advanced the treatment of viral infections in immunodeficient patients. CMVST usually uses the same donor as hematopoietic stem cell transplantation. CMVST should be administered to UCBT patients because of the absence of donors after UCBT. In China, there is no report on the use of CMVST to treat CMV infection after UCBT, and foreign reports are also limited. This paper reported a 20-year-old male patient with acute myeloid leukemia who developed cytomegalovirus retinitis (CMVR) after umbilical cord blood transplantation. After ineffective viral treatment, he was treated with a third-party donor CMVST and was successfully transformed into CMV nucleic acid negative. [ABSTRACT FROM AUTHOR]

Exercise training is not only a necessary means to improve the level of exercise, but also an important means to improve the body's immunity. Different time, intensity, items, and forms of exercise training have different effects on the body's immune function. As a double-edged sword to improve the body's immune function, exercise training is a different reaction mechanism of different immune cells after exercise training. This paper combined with foreign scholars' studies on the immune function of the body of literature from different exercise intensity, different time, different sports, different movement forms, and different external environment such as angle of view for athletes body's immune cells and humoral immunity summarized the various indexes such as combing, in order to help academia, medicine, and sports. It provides enlightenment to the contemporary public on how to participate in sports training more healthily. [ABSTRACT FROM AUTHOR]
