Colon cancer-related anemia (CCRA) is mainly caused by systemic inflammation, intestinal bleeding, iron deficiency and chemotherapy-induced myelosuppression in colon cancer. However, the best therapeutic schedule and related mechanism on CCRA were still uncertain. Studies on blood enrichment and anti-tumor effects of combined Danggui Buxue Decoction (DBD), Fe and rhEPO based on CCRA and gut microbiota modulation were conducted in this paper. Here, CCRA model was successfully induced by subcutaneous inoculation of CT-26 and i.p. oxaliplatin, rhEPO + DBD high dosage + Fe (EDF) and rhEPO + DBD high dosage (ED) groups had the best blood enrichment effect. Attractively, EDF group also showed antitumor activity. The sequencing results of gut microbiota showed that compared to P group, the relative abundances of Lachnospiraceae and opportunistic pathogen (Odoribacter) in ED and EDF groups were decreased. Interestingly, EDF also decreased the relative abundances of cancer-related bacteria (Helicobacter, Lactococcus, Alloprevotella) and imbalance-inducing bacteria (Escherichia-Shigella and Parabacteroides) and increased the relative abundances of butyrate-producing bacteria (Ruminococcaceae_UCG-014), however, ED showed the opposite effects to EDF, this might be the reason of the smaller tumor volume in EDF group. Our findings proposed the best treatment combination of DBD, rhEPO and Fe in CCRA and provided theoretical basis and literature reference for CCRA-induced intestinal flora disorder and the regulatory mechanism of EDF.

ObjectiveTo investigate the role of host immune system in the pathogenesis of encephalitis induced by Angiostrongylus cantonesis (A.C.) infection. MethodsThe definitive hosts of A.C. are rats and the intermediate hosts are mice. SD rats and BALB/c mice infected with A.C. were used to observe the changes of central immune organ thymus and peripheral immune organ spleen after 21 days of infection. Flow cytometry was used to detect the changes of cell subtypes in the thymus and spleen of rats and mice . ResultsAfter 21 days of infection with A.C. in rats, there was no obvious change in the appearance of spleen and thymus gland, and no obvious change in the thymus cell total count and in the proportion and number of thymocyte subtype cell (CD4+T, CD8+T, CD4+ CD8+T and CD4- CD8-T cells) between control groups and infected groups were found(P>0.05); The proportion and number of CD4+T cells in spleen was increased(P=0.016;P=0.023), while the change of CD8+T cells was not obvious(P>0.05). After 21 days of infection, the spleen and thymus of mice were severely atrophied, the total number of thymus cell was decreased sharply(P<0.000 1);The proportion and number of CD4+CD8+T cells were decreased obviously(P<0.000 1;P<0.000 1); Infection resulted in a decrease in the total number of mononuclear cells in the spleen of mice(P<0.000 1);The number of CD4+T cells and CD8+T cells in spleen was increased(P<0.000 1; P=0.003 8). ConclusionsA.C. infection severely suppressed the immune system of mice, but had little effect on rats. A.C. infection induced immunosuppression in the host, in turn reduced the ability of the host to clear and resist parasites, which may be an important mechanism of immune escape of parasites. This study revealed that the immune system plays an important role in the pathogenesis of encephalitis caused by A.C. infection, which provides a new idea for the prevention and treatment of encephalitis caused by A.C. infection.

Objective: To investigate the efficacy and predictors of autologous hematopoietic stem cell transplantation (auto-HSCT) in the treatment of T lymphoblastic lymphoma (T-LBL) . Methods: 41 patients with T-LBL who underwent auto-HSCT from April 2006 to July 2017 in the Department of Hematology, the First Affiliated Hospital of Soochow University and the Department of Lymphoma, Peking University Cancer Hospital were analyzed retrospectively. Results: ①Among 41 patients, there were 30 males and 11 females with median age of 24 (11-53) years old. According to the Ann Arbor staging, 33 (80.5%) patients were in stage Ⅲ/Ⅳ. 12 (29.3%) patients have mediastinal involvement, and 20 (48.8%) patients have bone marrow (BM) involvement. Before transplantation, there were 26 (63.4%) patients who achieved first complete remission (CR(1)) , the other 15 (36.6%) patients were in the non-CR(1) group, and there were 29 (70.7%) patients in the low-intermediate risk group (IPI<3 scores) , the other 12 (34.1%) patients were in the middle-high risk group (IPI≥3 scores) . ②The median follow-up was 29 (3-98) months. The 3-year overall survival (OS) and progression-free survival (PFS) for 41 patients were (64.3±8.2) % and (66.0±7.8) %, respectively. 3-year cumulative recurrence rate (CIR) was (30.7±7.4) %, and 3-year non-recurring mortality (NRM) was (4.8±4.6) %. ③The 3-year OS of the CR(1) group and the non-CR(1) group were (83.4±7.6) % and (38.9±12.9) % (P=0.010) , and the 3-year PFS of two groups were (83.8±7.4) % and (40.0±12.6) % (P=0.006) , respectively. The 3-year CIR of these two groups were (16.2±7.4) % and (53.3±12.9) % (P=0.015) , and the 3-year NRM were 0 and (14.3±13.2) % (P=0.157) , respectively. ④The 3-year OS of the IPI low-intermediate risk group and the high-intermediate risk group were (76.9±8.4) % and (35.7±15.2) % (P=0.014) and the 3-year PFS were (77.4±8.2) % and (40.0±14.6) (P=0.011) , respectively. The 3-year CIR of these two groups were (18.1±7.3) % and (60.0±14.6) % (P=0.006) , and the 3-year NRM were (5.6±5.4) % and 0 (P=0.683) , respectively. The OS and PFS of patients with low-intermediate risk group were significantly higher than the other group. Conclusion: Auto-HSCT could improve the survival of T-LBL. Pre-transplant status and IPI score are important predictors for survival T-LBL patients with auto-HSCT.

The combination of ginkgo ketoester tablet - donepezil (GD) is a popular combination commonly used in clinic for the treatment of Alzheimer's disease. To evaluate the learning and memory improving ability of different proportions of the two drugs. We optimized the ratio of GD for treatment of dementia using a mouse model. Dementia was induced by multiple neuronal damages in mice. The experimental protocols were approved by the Animal Experimental Ethical Committee of Nanjing University of Chinese Medicine and all the procedures were strictly conducted in accordance with ethical principle of animal use and care. Morris water maze, brain hematosylin-eosin staining and the changes of the neurotransmitters and related enzymes in the plasma or brain tissues were tested to determine the effect of GD on dementia mice. The results showed that the dementia mice were significantly different from the normal group in terms of behavior, pathological sections and related indicators. Compared to the dementia mice, partial administration groups could improve learning and memory ability as well as indexes in the blood and brain tissues. Both the principal component analysis and multi-attribute comprehensive index methods were used to comprehensively evaluate the total effect of GD on anti-dementia. The results showed that the combination of two drugs at the dose of 0.5 to 1 times was in a dose-effect relationship, and the dose of 1 (the clinical equivalent) had the best treatment effect. Then based on the optimal dose, GD 1∶1 had best effect, which was consistent with the clinical use of two drugs. This provides scientific basis for more effective application of the compatibility between ketoester tablet and donepezil for modern clinic medicine.
