OBJECTIVE:
To explore the synergistic effect of flumatinib (FLU) combined with histone deacetylase inhibitor chidamide (CHI) and underlying mechanism on Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) SUP-B15 cells.
METHODS:
CCK-8 method was used to examine the effects of FLU, CHI alone and combination therapy on the proliferation of SUP-B15 cells. Flow cytometry was utilized to analyze the cell cycle and apoptosis. RT-qPCR and Western blot methods were performed to detect target gene expression.
RESULTS:
FLU combined with CHI significantly inhibited the proliferation, induced G0/G1 phase arrest, and increased the apoptosis rate in SUP-B15 cells compared with FLU and CHI alone. The 50 genes were identified by overlapping the two drugs' targets of action with Ph+ ALL oncogenic genes in the public databases, and p53 and c-Myc transcription factors and PI3K/AKT signaling pathways were enriched in the overlapped genes. The combination of FLU and CHI significantly reduced the mRNA level of BCR::ABL fusion gene, up-regulated the protein and mRNA levels of p53, BAX, and Caspase-3, and down-regulated the protein and mRNA levels of c-Myc, PIK3CA, PIK3CB, and AKT2 compared with single-drug therapy. The analysis of GEO database and our center cohort showed that c-Myc, PIK3CA, PIK3CB, and AKT2 were significantly up-regulated while p53 was down-regulated in Ph+ ALL patients compared to healthy controls.
CONCLUSION
FLU combined with CHI synergistically inhibits cell proliferation, promotes apoptosis, and induces cycle arrest by targeting the PI3K/AKT signaling pathway through the p53/c-Myc axis in Ph+ ALL.

OBJECTIVES:
To analyze the differences in the prognosis of gastric signet ring cell carcinoma (SRCC) among different races using the US Surveillance Epidemiology and End Results (SEER) database and The Cancer Genome Atlas (TCGA) database.
METHODS:
We analyzed the data of patients with gastric SRCC from the SEER database from 2000 to 2020, and divided the patients into cohorts of whites, blacks, Asians or Pacific Islanders, American Indians/Alaska Natives according to their race. The prognosis and treatment of the cohorts were evaluated using baseline demographic analysis, Kamplan-Meier survival curve, and nomogram analysis.
RESULTS:
We analyzed the data of a total of 2058 patients, including 8.6% blacks, 72.4% whites, 16.6% Asians or Pacific Islanders, 1.0% American Indians/Alaska Natives, and 1.4% other races. The tumor grade varied among different races, and the prevalence and survival rates of patients differed significantly across races. The differences in the white cohort were the most prominent, and all the differences were statistically significant (P<0.05). Racial differences were also noted in patient management and prognosis.
CONCLUSIONS
There are racial differences in tumor grades and prognosis of gastric SRCC, and these differences provide evidence for optimizing clinical diagnosis and treatment strategies for this malignancy.

BACKGROUND:
Tracheal, bronchus, and lung cancer (TBL) is a major cause of mortality and top contributor to productivity loss in large emerging economies such as the BRICS (Brazil, Russia, India, China, and South Africa). We examined the time trends of TBL mortality across the BRICS to better understand the disease burden in these countries and inform public health and healthcare resource allocation.
METHODS:
TBL mortality-related data between 1990 and 2019 were obtained from the Global Burden of Disease Study 2019 and analyzed using age-period-cohort models. Net drift (local drift) was used to describe the expected age-adjusted TBL mortality rate over time overall (each age group); the longitudinal age curve was used to reflect the age effect; the period rate ratios (RRs) were used to reflect the period effect; and the cohort RR was used to reflect the cohort effect.
RESULTS:
In 2019, there were 958.3 thousand TBL deaths across the BRICS, representing 46.9% of the global TBL deaths. From 1990 to 2019, the age-standardized mortality rate (ASMR) of TBL decreased in Russia, Brazil, and South Africa while increased in China and India, with the largest reduction reported in Russia (-29.6%) and the largest increase in China (+22.4%). India showed an overall increase (+15.7%) in TBL mortality but the mortality risk decreased among individuals born after 1990 (men) and 1995 (women). Although South Africa and Brazil experienced an overall decline in TBL mortality, their recent birth cohorts, such as Brazilian individuals born after 1985 (men) and 1980 (women), and South African men born after 1995, had an increasing TBL mortality risk. China has experienced an overall increase in TBL mortality, with the mortality risk rising among individuals born after 1995 for both men and women. Russia, which had the highest TBL mortality among the BRICS countries in 1990, has demonstrated significant improvement over the past three decades.
CONCLUSIONS
Over the past 30 years, the BRICS accounted for an increasing proportion of global TBL mortality. TBL mortality increased in older women in all the BRICS countries except Russia. Among the recent birth cohort, the risk of TBL mortality increased in Brazil, China, and South Africa. More effective efforts are needed in the BRICS to reduce the burden of TBL and help achieve the United Nation's Sustainable Development Goals.

OBJECTIVE:
To explore the genetic basis for a rare case of acute B-lymphocytic leukemia (B-ALL) with double Philadelphia chromosomes (Ph) and double derivative chromosome 9s [der(9)].
METHODS:
A patient with double Ph and double der(9) B-ALL who presented at Shanghai Zhaxin Intergrated Traditional Chinese and Western Medicine Hospital in June 2020 was selected as the subject. Bone marrow morphology, flow cytometry, G-banding karyotyping, fluorescence in situ hybridization (FISH), genetic testing and chromosomal microarray analysis (CMA) were used to analyze bone marrow samples from the patient at various stages.
RESULTS:
At initial diagnosis, the patient's bone marrow morphology and flow immunotyping have both supported the diagnosis of B-ALL. G-banded karyotyping of the patient indicated double Ph, in addition with hyperdiploid chromosomes involving translocations between chromosomes 9 and 22. BCR-ABL1 fusion gene was positive. Genetic testing at the time of recurrence revealed presence of a heterozyous c.944C>T variant in the kinase region of the ABL1 gene. FISH showed a signal for ABL1-BCR fusion on both chromosome 9s. CMA showed that the mosaicism homozygosity ratio of chromosome 9 was about 40%, and the mosaicism duplication ratio of chromosome 22 was about 43%.
CONCLUSION
Since both der(9) homologs were seen in 40% of cells, the possible mechanism for the double der(9) in this patient may be similar to that of double Ph, which might have resulted from non-disjunction during mitosis in the Ph chromosome-positive cell clone.

Objective: To summarize the clinical data and prognosis of children with Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) common genes. Methods: This was a retrospective cohort study.Clinical data of 56 children with Ph-like ALL common gene cases (Ph-like ALL positive group) treated from January 2017 to January 2022 in the First Affiliated Hospital of Zhengzhou University, Henan Children's Hospital, Henan Cancer's Hospital and Henan Provincial People's Hospital were collected, 69 children with other high-risk B cell acute lymphoblastic leukemia (B-ALL) at the same time and the same age were selected as the negative group. The clinical characteristics and prognosis of two groups were analyzed retrospectively. Comparisons between groups were performed using Mann-Whitney U test and χ2 test. Kaplan-Meier method was used for survival curve, Log-Rank test was used for univariate analysis, and the Cox regression model was used for multivariate prognosis analysis. Results: Among 56 Ph-like ALL positive patients, there were 30 males and 26 females, and 15 cases were over 10 years old. There were 69 patients in Ph-like ALL negative group. Compared with the negative group, the children in positive group were older (6.4 (4.2, 11.2) vs. 4.7 (2.8, 8.4) years), and hyperleukocytosis (≥50×109/L) was more common (25% (14/56) vs. 9% (6/69)), the differences were statistically significant (both P<0.05). In the Ph-like ALL positive group, 32 cases were positive for IK6 (1 case was co-expressed with IK6 and EBF1-PDGFRB), 24 cases were IK6-negative, of which 9 cases were CRLF2 positive (including 2 cases with P2RY8-CRLF2, 7 cases with CRLF2 high expression), 5 cases were PDGFRB rearrangement, 4 cases were ABL1 rearrangement, 4 cases were JAK2 rearrangement, 1 case was ABL2 rearrangement and 1 case was EPOR rearrangement. The follow-up time of Ph-like ALL positive group was 22 (12, 40) months, and 32 (20, 45) months for negative group. The 3-year overall survival (OS) rate of positive group was significantly lower than the negative group ((72±7) % vs. (86±5) %, χ2=4.59, P<0.05). Compared with the 24 IK6-negative patients, the 3-year event free survival (EFS) rate of 32 IK6 positive patients was higher, the difference was statistically significant ((88±9) % vs. (65±14) %, χ2=5.37, P<0.05). Multivariate Cox regression analysis showed that the bone marrow minimal residual disease (MRD) not turning negative at the end of first induction (HR=4.12, 95%CI 1.13-15.03) independent prognostic risk factor for patient with Ph-like ALL common genes. Conclusions: Children with Ph-like ALL common genes were older than other high-risk B-ALL patients at diagnosis, with high white blood cells and lower survival rate. The bone marrow MRD not turning negative at the end of first induction were independent prognostic risk factor for children with Ph-like ALL common gene.

UNLABELLED:
AbstractObjective: To explore the effect of Philadelphia chromosome karyotype (Ph) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) on the treatment of acute lymphoblastic leukemia (ALL).
METHODS:
The data of 429 patients with all from January 2012 to December 2020 were retrospectively analyzed. According to the results of cytogenetic karyotype analysis, they were divided into Ph+ group (n=64), Ph- monomeric karyotype (MK) group (n=53) and Ph- NMK group (n=312). According to the treatment plan, they were divided into allo-HSCT group (n=236) and non-allo-HSCT group (n=193). The effects of karyotype and allo-HSCT on the short-term and long-term outcomes of all patients were analyzed.
RESULTS:
Among the 429 patients, 6 (1.40%) died during induction therapy, 60 (13.99%) had no response, 363 (84.62%) achieved complete remission (CR) and 287 (66.90%) achieved minimal residual disease negative (MRD-). There was no significant difference in short-term efficacy (CR%, CR1%, MRD-%) among Ph+ group, Ph- MK group and Ph- non-MK group (P>0.05). The median OS was 6.9 months (95% CI: 4.6-8.2 months) for 60 unresponsive patients and 39.8 months (95% CI: 28.6-45.9 months) for 363 CR patients. There was no significant difference in the long-term efficacy [5-year cumulative recurrence rate (CIR%), disease-free survival rate (DFS%) and overall survival rate (OS%) among Ph- group, Ph- MK group and Ph- non-MK group (P>0.05). Among 429 patients, 55.01% (236/429) underwent allo-HSCT. The short-term efficacy (CR%, MRD-%) and long-term efficacy (CIR%, DFS%, OS%)] of patients with allo-HSCT after more than 2 consolidation cycles were better than those of patients with non-allo-HSCT (P<0.05). For the three subgroups of Ph+ group, Ph- MK group and Ph- non-MK group, the short-term and long-term efficacy of allo-HSCT patients was better than that of non-allo-HSCT patients. Multivariate logistic regression analysis showed that liver/spleen/lymph node enlargement was a risk factor for CIR, DFS and OS, with adjusted or of 1.23 (95% CI: 1.08-2.78, P=0.032), 1.21 (95% CI: 1.03-2.34, P=0.038) and 1.25 (95% CI: 1.08-2.97, P=0.028), respectively. No transplantation was a risk fator for CIR, DFS, OS. The adjusted or were 2.34 (95% CI: 1.18-5.39, P<0.001), 2.15 (95% CI: 1.10-4.34, P<0.001) and 2.28 (95% CI: 1.09-4.11, P<0.001), respectively.
CONCLUSION
Karyotype (Ph+/- and MK/non-MK) seems to have no effect on the short-term and long-term efficacy of all patients; allo-HSCT can affect the short-term and long-term efficacy of all patients and improve their prognosis; liver/spleen/lymph node enlargement and non-implementation of allo-HSCT treatment strategy are the risk factors for poor prognosis of all patients.

With 12 representative states such as Ohio and Illinois as examples, the disciplinary system for acupuncturists in the United States is introduced. The disciplinary system mainly covers several aspects such as the subject of the implementation, the types of illegal acts, the form of disciplinary responsibility, and the hearing procedure. The acupuncture industry association has the responsibility of disciplinary action in most states. Corresponding disciplinary measures will be taken depending on the illegal activities of acupuncturists according to the types of illegal practice specified by each state. The hearing procedure provides procedural guarantee for the subsequent rights protection activities of acupuncturists.

BACKGROUND:
Given the important repercussions that sociodemographic factors can have on physical activity, especially in the field of leisure, and cardiometabolic risk, it seems relevant to analyze the implications of these variables on the relationship between physical activity in leisure time (LTPA) and cardiometabolic risk. In this sense, the present study aims to verify the moderating role of biologic and socioeconomic factors in the relationship between LTPA and cardiometabolic risk in adolescents in southern Brazil.
METHODS:
Cross-sectional study that included 1596 adolescents selected at random (58.2% girls), aged between 10 and 17 years. LTPA, biological and socioeconomic factors were assessed using a self-reported questionnaire and the cardiometabolic risk score (total cholesterol/HDL-c ratio, triglycerides, fasting glucose, systolic blood pressure, and waist circumference, considering the participant's age and sex) was included as an outcome. Associations and moderations were tested by multiple linear regression models.
RESULTS:
It was observed a positive interaction of LTPA and sex (p = 0.048) and LTPA and school system (p = 0.037), and negative interaction of LTPA and skin color (p = 0.040), indicating that these factors were moderators in the relationship between LTPA and clustered cardiometabolic risk score (cMetS) in adolescents. A reduction in cardiometabolic risk was observed according to the increase in weekly minutes of LTPA among boys, non-white adolescents, and students from municipal schools.
CONCLUSIONS
The association between LTPA and cardiometabolic risk was moderated by sex, skin color, and school system in adolescents from southern Brazil.

Journal of Experimental Hematology 2021;29(6):1869-1874
OBJECTIVE:
To investigate the overview of thrombosis in myeloproliferative neoplasms(MPN) patients, and to explore the risk factors of thrombosis at diagnosis and during follow-up.
METHODS:
The clinical data of 388 MPN patients treated in our hospital were collected. The patients were followed up by outpatient and phone. The risk factors of thrombosis were analyzed by statistical methods.
RESULTS:
Among 388 MPN patients, 161 patients (41.49%) showed thromboses at diagnosis or during follow-up. Among them, 92.55% were arterial thromboses, 146 cases (96.27%) were complicated with thromboses at diagnosis, and 36 cases (11.46%) showed newly thromboses or progression of previous thromboses among the 314 received full follow-up patients. Age (P<0.001, HR:1.033, 95%CI:1.016-1.051), JAK2V617F mutation (P=0.037, HR:1.72, 95%CI: 1.033-2.862), hypertension (P<0.001, HR:2.639, 95%CI:1.659-4.197) and hyperlipidemia (P<0.001, HR:2.659, 95%CI:1.626-4.347) were the independent risk factors affecting thrombosis at diagnosis of the patients. During the follow-up, age (P=0.016, HR:1.032, 95%CI: 1.006-1.059) and previous thrombosis history (P=0.019, HR:2.194, 95%CI: 1.135-4.242) were the independent risk factors affecting the progression of thrombosis at different sites or on the basis of the previous thrombosis in the patients.
CONCLUSION
Patients with advanced age, JAK2V617F mutation or complicated with hypertension and hyperlipidemia shows a higher risk of thrombosis at diagnosis, while the patients with advanced age or previous thrombosis history shows a higher risk of progression of thrombosis during the follow-up.
