Gastric cancer is one of the most com-mon malignant tumors in the digestive system,which often occurs in middle-aged and elderly peo-ple.Traditional Chinese medicine recognizes gastric cancer as a kind of tumor characterized by fluid de-ficiency,heat accumulation and the growing bind-ing of toxins in the stomach.It is commonly treated with heat-clearing and detoxifying drugs in clinical practice.Hedyotis diffusa-Scutellaria barbata herb pair(HS)has the effects of clearing heat and detoxi-fying,promoting blood circulation,resolving car-buncle and expulsing boil,anti-inflammatory and analgesic,which are consistent with the etiology and pathogenesis of gastric cancer,therefore,it can be used for the treatment of gastric cancer.Modern pharmacological researches have con-firmed that HS can play an anti-gastric cancer role by inducing cell apoptosis,inhibiting cell prolifera-tion,inhibiting angiogenesis,improving immune mi-croenvironment and down-regulating telomerase activity.Herein,this review summarizes the active ingredients and related mechanism responsible for the anti-gastric cancer effect of HS,which will pro-vide the theoretical basis for its clinical use and the development of new drugs against gastric cancers.

Objective:To compare the efficacy of haplotype hematopoietic stem cell transplantation (HIDT) and sibling matched hematopoietic stem cell transplantation (MSDT) in the treatment of complete remission (CR) acute T-lymphoblastic leukemia (T-ALL) .Methods:We retrospectively analyzed the clinical characteristics and outcomes of 98 patients who underwent HSCT in Hebei Yanda Ludaopei hospital with HID ( n=81) or ISD ( n=17) between May 2012 and May 2016. Results:The incidence of grades 2-4 and 3-4 acute-versus-host disease 100 days after HSCT were 51.9% (95% Confidence interval [ CI] 42.0%-64.0%) vs 29.4% (95% CI 14.1%-61.4%) ( P=0.072) and 9.8% (95% CI 5.1%-19.1%) vs 11.8% (95% CI 3.2%-43.3%) ( P=1.000) for HIDT and MSDT. The 100-day cumulative incidences of CMV and EBV viremia were 53.1% (95% CI 43.3%-65.2%) vs 29.4% (95% CI 14.1%-61.4%) ( P=0.115) and 35.8% (95% CI 26.8%-47.9%) vs11.8% (95% CI 3.2%-43.3%) ( P=0.048) . The 5-year overall survival, leukemia-free survival, cumulative incidences of relapse, and no-relapse mortality were 60.5% (95% CI 5.4%-49.0%) vs 68.8% (95% CI 11.8%-40.0%) ( P=0.315) , 58.0% (95% CI 5.5%-46.5%) vs 68.8% (95% CI 11.8%-40.0%) ( P=0.258) , 16.1% (95% CI 9.8%-26.4%) vs 11.8% (95% CI 3.2%-43.3%) ( P=0.643) , 25.9% (95% CI 17.9%-37.5%) vs 19.4% (95% CI 6.9%-54.4%) ( P=0.386) for HIDT and MSDT, respectively. Conclusion:HID could be a valid alternative donor for patients with T-ALL in CR lacking an identical donor.

Objective:To study the clinical results and prognostic factors for allo-HSCT of Philadelphia chromosome-positive (Ph +) acute lymphoblastic leukemia (ALL) in complete remission (CR) in the era of tyrosine kinase inhibitors (TKI) . Methods:We performed a retrospective analysis of the clinical characteristics of 116 patients with Ph +ALL who underwent allo-HSCT while in CR. Results:The study population included 72 men and 44 women. The median patient age was 20 years (4-64 years) . The patients received sibling-identical donor ( n=21) , haplo ( n=77) , and unrelated donor ( n=18) HSCT. The overall survival (OS) rate at 5 years was 73.2% (95% CI 63.8% -80.5% ) . In particular, the 5-year OS can reach 87.5% when the time from diagnosis to transplant is <180 days. The 5-years DFS was 61.4% (95% CI 51.8% -69.7% ) , the 5-year molecular and morphology cumulative relapse incidence was 18.5% (95% CI 12.6% -27.3% ) , and the 5-year TRM was 19.9% (95% CI 13.8% -28.7% ) . A multivariate analysis showed that an age range of 15-39 years ( HR=2.730, P=0.044) , time from diagnosis to HSCT ≥ 180 days ( HR=4.534, P=0.010) , and Ⅲ-Ⅳgrade aGVHD ( HR=7.558, P=0.000) were significantly associated with an inferior overall survival. Limited cGVHD subgroup had better OS ( HR=0.300, P=0.034) . Sex, WBC count at diagnosis, type of BCR-ABL fusion genes, somatic gene mutations, CR 1 or >CR 1, MRD negative or positive, conditioning regimen based on TBI or Bu, conditioning intensity, donor source, GVHD prophylactic proposal using cyclosporine or tacrolimus, presence/absence of CMV viremia, and presence/absence of EBV viremia were not significantly different in terms of the OS and DFS. Conclusion:Factors influencing the overall survival of Ph + ALL patients who underwent allo-HSCT in CR in the TKI era include age, time form diagnosis to HSCT, and aGVHD severity.

Objective:To evaluate the association of TP53 mutations with the clinical outcomes of Ph-negative B-ALL following allogeneic hematopoietic stem cell transplantation (allo-HSCT) .Methods:Total 300 patients with Ph-negative B-ALL who underwent allo-HSCT at the Hebei Yanda Ludaopei Hospital from May 2012 to May 2017 were retrospectively analyzed; their clinical characteristics, TP53 gene mutation type, and association between TP53 mutations and transplantation outcomes, including leukemia-free survival (LFS) , overall survival (OS) , non-relapse mortality (NRM) , relapse, and GVHD, were evaluated.Results:Total 23 patients had TP53 mutations; all the TP53 mutations affected P53’DNA-binding domain. The 5-year-LFS, OS, and RI were 34.8% and 62.3% ( P=0.001) , 41.9% and 65.1% ( P=0.020) , and 47.8% and 14.8% ( P=0.000) , respectively, for TP53 mutations and wild-type TP53 patients. However, there were no significant differences in NRM and GVHD. Multivariate analysis showed that TP53 mutations remained adverse prognostic factors for LFS, OS, and RI after allo-HSCT. Conclusion:Some patients with TP53 mutations can achieve long-term survival with allo-HSCT. TP53 mutations are adverse prognostic factors for Ph-negative B-ALL patients who undergo allo-HSCT.
