RESUMEN
At present, immunotherapy is in full swing in the treatment of non-small cell lung cancer, melanoma, bladder cancer and other tumor species, and its treatment methods are also diverse, including tumor vaccine treatment, adoptive T cell therapy, immune checkpoint inhibitor treatment, etc, but current immunotherapy for colorectal cancer mainly focuses on immune checkpoint inhibitors (PD-1/PD-L1 and CTLA-4 inhibitors). Since PD-1/PD-L1 inhibitors have shown amazing efficacy in patients with dMMR/MSI-H advanced colorectal cancer, immune checkpoint inhibitors have gained more and more attention in the field of colorectal cancer, and the treatment options have gradually shifted from late line treatment to first-line treatment or neoadjuvant therapy, and have achieved success. This paper summarizes the research progress of immune checkpoint therapy on colorectal cancer.
RESUMEN
Objective To analyze the efficacy of umbilical one trocar laparoscopic appendectomy (UOTLA) in treatment of complicated appendicitis in children. Methods Clinical data of 78 cases of children patients with complicated appendicitis from January 2012 to October 2015 was summarized, including 44 cases as UOTLA group received umbilical one trocar laparoscopic appendectomy, 34 cases as OA group received open appendectomy. Then statistically analyzed all the patients' operation time, postoperative hospital stay, postoperative abdominal abscess, incision infection, early inflammatory intestinal obstruction and pain level. Results The laboratory test results of C reaction protein (CRP) had no significant difference between the two groups, while peripheral white blood cell count decreased more significantly in UOTLA group than that in OA group; the operation time of UOTLA group was shorter than that in OA group with no statistical difference [(66.59 ± 33.24) vs (72.86 ± 30.36) min, P > 0.05], but postoperative hospital stay was shorter [(8.21 ± 1.67) vs (9.21 ± 2.01) d, P 0.05); incision infection: 6 cases in UOTLA group, 9 cases in OA group (P > 0.05); early inflammatory intestinal obstruction: 1 cases in UOTLA group, 5 cases in OA group (P > 0.05); the pain level, postoperative recovery time was significantly shorter in UOTLA group compared with OA group (P 0.05]. Conclusion UOTLA is safe and effective for complicated appendicitis in children due to minimally invasive, less pain and faster recovery without significant increase in the cost and postoperative complications. It can be applied in children with purulent, perforated appendicitis and gangrene, perforated appendicitis and other complicated appendicitis.
RESUMEN
Objective To investigate the effect of gastric capsule combined with psychological intervention on immune function and quality of life in patients with advanced gastric cancer.Methods A total of 130 patients with advanced gastric cancer were enrolled in this studyfrom July 2014 to August 2016 in our hospital,andrandomly divided into two groups.Twogroups were treated with chemotherapy,andobservation group was treated anotherwithWeinaian capsule.The immune indexes, quality of life and side effects of the 2 groups before and after chemotherapy were compared and analyzed.Results After chemotherapy,CD4+、CD8+、CD4+/CD8+、CD3+ and NKlevel of observation group were better than that of control group(all P<0.05).After chemotherapy,SF-36 score of physical function, health status, vitality, emotional and mental health scores of observation group werebetter than that of control group(all P<0.05).During chemotherapy,proportion of gastrointestinal reaction and liver and kidney injury of observation group were 35.38% and 21.54%,lower than that of control group 63.08% and 40.00%(all P<0.05).Conclusion Weinaian capsule can improve immunologic function of advanced gastric cancer patients undergoing chemotherapy and reduce adverse reactions,so as to improve the quality of life of patients.
RESUMEN
Chickens were infected with chicken anemia virus (CAV) at one-day-old and vaccinated with La Sota vaccine 8 days later. Meanwhile, uninfected chickens were vaccinated as controls. At 7, 14 and 28 days post vaccination, the content of IgG,IgM,IgA and HI titer in serum, the number of T cells, IgG, IgM and IgA antibody producing cells in thymus, bursa and spleen, the proliferative response of T、B cells, the inductive activity of interleukin 2 (IL-2) and interferon (IFN) in thymus and spleen were tested. The results showed that the content of IgG, IgM, IgA and hemoagglutination inhibition (HI) titer in serum, the number of T cells, IgG, IgM and IgA antibody producing cells in thymus, bursa and spleen, the proliferative response of T cells and B cells as well as the inductive activity of IL-2 and IFN in thymus and spleen of infected-vaccinated chickens significantly decreased compared with the control. These results indicated that the immunofunction and immunoregulation were dropped post ND vaccination of CAV-infected chickens.
