Objective To investigate the therapeatic effects of chemical thoracic sympathectomy (CTS) for Raynaud disease. Methods A niddle was injected into the first or second thoraic vertebra from back. A X-ray examination was performed to definite the position of the niddle tip. One millilitre of urographine was injected to determine if it was infused into thoracic cavity. If not, 2 ml of 5% phenol was injected and the niddle was removed. Results Within 10 minutes both pairs of the hands of the two patients with Raynaud's disease turned into flushing and warm from pallor and cool after CTS. Ice-water test changed to negative. Conclusions CTS is of simple, microinvasive and low cost procedure for Raynaud's disease.

Objective To construct early phase Ⅰ cardiopulmonary rehabilitation program for patients with Type A aortic dissection and to evaluate its clinical effects.Methods From January 2021 to October 2022,type A aortic dissection patients of a tertiary hospital in Beijing was selected by the destination sampling.They were divided into a control group and an intervention group.The intervention group was given early phase Ⅰcardiopulmonary rehabilitation program for patients with type A aortic dissection and the control group was given routine care.The 6-minute walking experiment(6MWT),Borg subjective fatigue score,the first time out of bed,the incidence of hypoxemia and related complications,and the incidence of adverse events related to rehabilitation nursing were compared between the 2 groups.Results A total of 130 cases were selected,among which 20 cases were excluded because of surgical complications and self-withdrawal.A total of 110 cases were finally included,with 57 cases in the intervention group and 53 cases in the control group.The results of walking distance of 6MWT,Borg subjective fatigue score and incidence of hypoxemia had statistical significance between the 2 groups(P＜0.05).The results of the time of the first time out of bed and the incidence of complications and the incidence of adverse events related to rehabilitation nursing had no statistical significance between the 2 groups(P＞0.05).Conclusion Early phase Ⅰ cardiopulmonary rehabilitation program for patients with type A aortic dissection benefits the improvement of the motor function,the reduction of incidence of hypoxemia.

The generation of T cells with maximal anti-tumor activities will significantly impact the field of T-cell-based adoptive immunotherapy. In this report, we found that OKT3/IL-2-stimulated T cells were phenotypically more heterogeneous, with enhanced anti-tumor activity in vitro and when locally administered in a solid tumor mouse model. To further improve the OKT3/IL-2-based T cell manufacturing procedure, we developed a novel T cell stimulation and expansion method in which peripheral blood mononuclear cells were electroporated with mRNA encoding a chimeric membrane protein consisting of a single-chain variable fragment against CD3 and the intracellular domains of CD28 and 4-1BB (OKT3-28BB). The expanded T cells were phenotypically and functionally similar to T cells expanded by OKT3/IL-2. Moreover, co-electroporation of CD86 and 4-1BBL could further change the phenotype and enhance the in vivo anti-tumor activity. Although T cells expanded by the co-electroporation of OKT3-28BB with CD86 and 4-1BBL showed an increased central memory phenotype, the T cells still maintained tumor lytic activities as potent as those of OKT3/IL-2 or OKT3-28BB-stimulated T cells. In different tumor mouse models, T cells expanded by OKT3-28BB RNA electroporation showed anti-tumor activities superior to those of OKT3/IL-2 T cells. Hence, T cells with both a less differentiated phenotype and potent tumor killing ability can be generated by RNA electroporation, and this T cell manufacturing procedure can be further optimized by simply co-delivering other splices of RNA, thus providing a simple and cost-effective method for generating high-quality T cells for adoptive immunotherapy.
