ABSTRACT
Chimeric antigen receptor T cell therapy in the CD19+blood system of malignant tumor has achieved astonishing re-sults.Targeting the CART CD19 cells can increase the remission rate of acute lymphoblastic leukemia.But the curative effect of CART therapy for solid tumors in recent years has been no substantive breakthrough.There are many problems to be solved in tumor immunotherapy of solid tumor.For example,how CART break through into solid tumor microenvironment and keep vitality,how to identify cancer cells accurately and how to surmount immunosuppression playing an effective role.We here discuss that targeting CART cells toward solid tumors faces certain circumstances critical for the therapeutic success.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of electroacupuncture on myoelectric activity of Jejunal limb after Roux-en-Y esophagojejunostomy.</p><p><b>METHODS</b>Fourteen health young pigs were randomly divided into 2 groups, an experimental group (total gastrectomy and Roux-en-Y esophagojejunostomy was carried out) and a control group (the abdominal cavity was closed after the electrode was placed), 7 pigs in each group. Electroacupunture was given at "Zusanli" (ST 36) in the experimental group. The changes of myoelectrogram of the jejunal limb was investigated.</p><p><b>RESULTS</b>Compared with the control group, the amplitude and the frequency of the slow wave, and the amplitude and incidence rate of the spike potential in the experimental group were changed significantly; the duration of migrating motor complex (MMC) phase III was (2.6 +/- 0.7) minutes in the experimental group, which was significantly shorter than (7.1 +/- 1.1) minutes in the control group. Electroacupuncture did not significantly influence the amplitude and the frequency of the slow wave, but could increased significantly the incidence rate and the amplitude of the spike potential; after electroacupuncture, the duration of MMC phase III was (5.7 +/- 0.9) minutes, which was significantly longer than (2.6 +/- 0.7) minutes before electroacupuncture.</p><p><b>CONCLUSION</b>Electroacupuncture at "Zusanli" (ST 36) can relieve the Roux-en-Y stasis syndrome through influencing myoelectric activity of the jejunum.</p>
