ObjectiveTo explore the effects of Bushen Jianpi prescription on the autophagy and phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway in the patients with aplastic anemia （AA）. MethodA total of 30 AA patients admitted to Xiyuan Hospital and 6 healthy donors who were prepared to undergo peripheral blood hematopoietic stem cell transplantation in 304 Hospital from September 2020 to August 2021 were enrolled and assigned into an AA group and a control group. The AA group was treated with Bushen Jianpi prescription combined with cyclosporin A （CsA） and androgen for 3 months. The mononuclear cells from bone marrow in the AA group before and after treatment and the peripheral blood of the control group were collected. Transmission electron microscopy was then employed to detect autophagosomes. Western blotting was employed to determine the protein levels of microtuble-associated protein 1 light chain 3 （LC3）Ⅰ， LC3Ⅱ， mTOR， phosphorylated （p）-mTOR， Akt， p-Akt， PI3K， and p-PI3K， and real-time polymerase chain reaction （PCR） to determine the mRNA levels of LC3， mTOR， Akt， and PI3K. ResultIn the AA group， the treatment was completed in 29 patients， and the total response rate was 51.72% （15/29）. ① The AA group showed lower levels of white blood cell （WBC）， hemoglobin （HGB）， platelet （PLT）， and absolute neutrophil count （ANC） in the peripheral blood （P<0.01） and lower number of intracellular autophagosomes than the control group before treatment. Moreover， the AA group showed lower mRNA level of LC3 （P<0.01） and protein levels of LC3Ⅰ and LC3Ⅱ （P<0.01） and higher mRNA levels of mTOR， Akt， and PI3Kα （P<0.01） and protein levels of Akt， p-Akt， PI3K， p-PI3K， mTOR， and p-mTOR （P<0.01） than the control group. ② In AA group， the levels of HGB and PLT elevated （P<0.05） and the number of intracellular autophagosomes increased after treatment compared with those before treatment. Moreover， the mRNA level of LC3 and the protein levels of LC3Ⅰ and LC3Ⅱ were up-regulated （P<0.01）， the mRNA levels of mTOR， Akt， and PI3Kα （P<0.01） and the protein levels of Akt， p-PI3K （P<0.01）， p-Akt， PI3K， mTOR， p-mTOR （P<0.05） were down-regulated after treatment. ConclusionAA patients show lower autophagy levels， while Bushen Jianpi prescription can effectively improve the autophagy level and down-regulated the expression of PI3K/Akt/mTOR signaling pathway in AA patients.

Comparison of Blood Routine Changes in Treatment of Aplastic Anemia by Kidney-tonifying and Blood-generating Method and Qi-promoting and Blood-nourishing Method and Mode of Treatment by Stages / 中国实验方剂学杂志

ObjectiveTo explore the clinical effect of kidney-tonifying and blood-generating method and qi-promoting and blood-nourishing method combined with western medicine on the treatment of aplastic anemia and the characteristics of blood routine recovery， and to explore a new phased treatment model for aplastic anemia. MethodThis study was based on a prospective， multicenter， double-blind， and randomized controlled clinical trial. Patients with aplastic anemia from 19 centers were analyzed and divided into a kidney-tonifying and blood-generating group and a Qi-promoting and blood-nourishing group， which were treated with traditional Chinese medicine （TCM） combined with western medicine. The clinical effect and the changes in blood routine in each group during treatment were evaluated. ResultDuring the observation period， 375 cases of aplastic anemia were included in two groups， and TCM syndrome differentiation conformed these cases as Qi-deficiency type and both Qi and blood-deficiency type. These cases were randomly divided into two groups， including 184 in the kidney-tonifying and blood-generating group and 191 in the Qi-promoting and blood-nourishing group， being treated by kidney-tonifying and blood-generating granules and Qi-promoting and blood-nourishing granules， respectively， and combined oral androgen and ciclosporin soft capsules. The treatment lasted for six months and was divided into three stages. Visits were conducted from the beginning of the treatment to the end of the first， fourth， and sixth months. The curative effect was evaluated six months later. The total effective rate of the kidney-tonifying and blood-generating group was 86.4% （159/184）， which was significantly better than that of the Qi-promoting and blood-nourishing group ［68.6% （131/191）， P<0.01）］. The results of the percentage quartile of blood cell growth in each stage of the 2 groups were analyzed. The hemoglobin concentration and platelet count of the patients in the kidney-invigorating blood group continued to increase after treatment, and significantly increased in the second and third stages compared with the first stage (P<0.05). The increase of reticulocyte count was most significant in the first stage of treatment (P<0.05). The reticulocyte count in supplementing Qi and nourishing blood group increased significantly in the first and second stages of treatment (P<0.05). The other observation indicators increased at each stage, but there was no statistical difference in the growth rate. The effects of the two groups were compared by stages. In the second stage of treatment, the increase of hemoglobin concentration in the kidney-invigorating blood group was better than that in the supplementing Qi-nourishing blood group (P<0.05). The increase of platelet count and red blood cell count in supplementing Qi and nourishing blood group was greater (P<0.05). In the third stage of treatment, the increase of hemoglobin concentration in the bushen Shengxue group was more significant (P<0.05). ConclusionThe overall effective rate of the kidney-tonifying and blood-generating method in the treatment of aplastic anemia is better than that of the Qi-promoting and blood-nourishing method， with significant effects and safety. This study has proposed a three-stage early treatment mode for aplastic anemia. The first and third stages (0-1, 5-6 months) were mainly treated by invigorating kidney and generating blood. In the second stage of treatment (2-4 months), invigorating kidney and generating blood combined with invigorating Qi and nourishing blood were adopted. It may be closer to the actual clinical treatment response and objective rule changes of aplastic anemia.

ObjectiveTo investigate the predictive indicators of early efficacy of Bushen Shengxue prescription combined with western medicine in the treatment of aplastic anemia， and provide prognosis indicators for the treatment of aplastic anemia （AA） with kidney-tonifying therapy in traditional Chinese medicine （TCM） combined with western medicine. MethodA total of 126 patients treated by Bushen Shengxue prescription combined with western medicine in 19 hospitals including Xiyuan Hospital of the China Academy of Chinese Medical Sciences from September 2018 to March 2021 were selected for a retrospective study. The therapy was proven to be effective after six months of treatment. According to the efficacy after 4 months of treatment， the patients were assigned into a 4-month effective group and a 4-month ineffective group. The age， sex， disease severity （including severe aplastic anemia and non-severe aplastic anemia）， course of disease， degree of bone marrow nucleated cell proliferation， baseline hemogram levels ［including white blood cell count （WBC）， absolute neutrophil count （ANC）， hemoglobin （HGB）， platelets （PLT）， and reticulocytes （RET）］， T lymphocytes subsets， and the expression levels of T-box transcription factor （T-bet） and GATA-binding protein-3 （GATA-3） were compared between the two groups before treatment. ResultThe proportions of patients within the age ranges of ［20， 40） and ［60， 80） were higher in the 4-month effective group （P<0.05）. The sex， disease severity， course of disease， and comorbidities had no significant differences between the two groups. The 4-month effective group had higher baseline levels of HGB， WBC， ANC， and PLT than the 4-month ineffective group （P<0.05）， and there was no significant difference in the RET level between the two groups before treatment. Binary Logistic regression analysis showed that the PLT level before treatment was an independent factor affecting the onset time， while other indicators did not affect the onset time. The receiver operating characteristic （ROC） curve was established to analyze the value of PLT level before treatment for predicting the onset time， and the area under the curve was 0.691. With the critical value of 40.5×109/L， the sensitivity and specificity of the prediction that the therapy will take effect within 4 months were 0.569 and 0.893， respectively. The two groups of patients were graded according to age ｛（14， 20）， ［20， 40）， ［40， 60）， and ［60， 80）｝ and PLT level before treatment （PLT<40×109/L， PLT≥40×109/L）. The proportion of the patients with PLT≥40×109/L before treatment in the 4-month effective group was significantly higher than that in the 4-month ineffective group （P<0.05）. The degree of bone marrow nucleated cell proliferation before treatment had no significant difference between the two groups. The level of total T lymphocytes in the 4-month effective patients was lower than that in the 4-month ineffective patients before treatment （P<0.05）. The levels of Th1 cells， Th2 cells， CD4+ T cells， and CD8+ T cells showed no significant differences between the two groups before treatment. The T-bet expression level in the 4-month effective group was higher than that in the 4-month ineffective group before treatment （P<0.05）， while the expression level of GATA-3 showed no significant difference between the two groups before treatment. ConclusionBushen Shengxue prescription combined with western medicine will achieve faster effect for the patients within the age ranges of ［20， 40） or ［40， 60）， with higher levels of HGB， WBC， ANC， and PLT （especially those with PLT≥40×109/L）， lower level of total T lymphocytes， or higher T-bet expression level before treatment.

Clinical Predominance Disease of Traditional Chinese Medicine： Gastroesophageal Reflux Disease / 中国实验方剂学杂志

Gastroesophageal reflux disease （GERD） is a frequently and commonly occurring disease in clinic. In recent decades， with the development in pathophysiology and drug researches， modern medicine has achieved remarkable progress and results in diagnosis and treatment. However， the treatments for non-erosive reflux disease， refractory gastroesophageal reflux disease， proton pump inhibitor resistance， overlap of disease symptoms， and extraesophageal symptoms are limited and ineffective. Traditional Chinese medicine （TCM） was widely used in clinical practice， which has been proved effective in relieving symptoms and improving the quality of life. Sponsored by China Association of Chinese Medicine （CACM） and undertaken by the Spleen and Stomach Disease Branch of CACM， "the 12th Youth Salon of Clinical Predominance Disease Series （GERD）" invited 18 authoritative digestive experts of TCM and western medicine to discuss "the difficulties of clinical diagnosis and treatment of GERD and TCM advantages". The focus issues such as modern medical diagnosis and treatment achievements and contributions， improvement and maintenance of symptoms， response to overlapping disease symptoms， reduction and withdrawal of acid suppressors， and treatment of extra-esophageal symptoms were discussed in depth. TCM and western medicine exchanged and complemented each other's strengths， combing the difficulties of modern medical diagnosis and treatment， which clarified the positioning and advantages of TCM and provided guidance for clinical and scientific research.

Analysis of Predictive Factors for Efficacy of Yiqi Yangxue Prescription Combined with Western Medicine in Treatment of Aplastic Anemia in Non-elderly Adults / 中国实验方剂学杂志

ObjectiveTo explore the predictive factors for the efficacy of Yiqi Yangxue prescription combined with western medicine in treating aplastic anemia （AA） in non-elderly adults， so as to provide a reference for predicting the prognosis of this therapy. MethodA retrospective study was conducted with the clinical data of non-elderly adult AA patients who visited 19 hospitals including Xiyuan Hospital of the China Academy of Chinese Medical Sciences from September 2018 to March 2021 and were treated with Yiqi Yangxue Prescription combined with western medicine. According to the efficacy evaluation results at the 6th month of treatment， the patients were assigned into effective and ineffective groups. The two groups were compared in terms of the gender， age， disease classification ［non-severe aplastic anemia （NSAA）/severe aplastic anemia （SAA）］， course of disease， family history， complications， history of drug allergy， baseline blood routine examination ［hemoglobin （HGB）， white blood cell （WBC）， neutrophil （ANC）， platelet （PLT）， and reticulocyte （Ret）］， T lymphocyte subsets， degree of proliferation of nucleated cells in bone marrow， and expression of T-bet and GATA-3. ResultA total of 101 non-elderly adult AA patients were enrolled in this study， including 81 in the effective group and 20 in the ineffective group. The effective group had a higher proportion of the patients without a history of drug allergy than the ineffective group （P<0.05）. The body height， body weight， gender， age， disease classification， course of disease， family history， and complications showed no significant differences between two groups. The effective group had higher levels of ANC and PLT before treatment （P<0.05） and higher proportion of patients with ANC≥1.6×109/L and PLT≥25×109/L （P<0.05， P<0.01） than the ineffective group. The baseline levels of WBC， HGB， and Ret showed no significant statistical differences between two groups. The levels of CD3+HLA-DR+T cells in the effective group before treatment was higher than that in the ineffective group （P<0.05）. The levels of CD3+CD19-T cells， CD4+T cells， CD8+T cells， Th1 cells， Th2 cells， and CD3+CD25+T cells showed no significant statistical differences between two groups before treatment. The proportion of patients with active bone marrow nucleated cells proliferation in the effective group before treatment were significantly higher than that in the ineffective group, while the proportion of patients with reduced or extremely reduced proliferation were significantly lower than that in the ineffective group （P<0.05）. The expression levels of T-bet and GATA-3 genes had no significant differences between two groups before treatment. The multivariate binary logistic regression analysis showed that the ANC level before treatment and history of drug allergy were independent influencing factors for efficacy （P<0.05， P<0.01）， while other indicators were not influencing factors for efficacy. The receiver operating characteristic （ROC） curve was applied to analyze the predictive value of the ANC level before treatment in the treatment of AA in non-elderly adults with Yiqi Yangxue prescription combined with western medicine. The area under the curve was 0.679 （P<0.05）， with the critical value of 1.595×109/L， the sensitivity of 0.42， and the specificity of 0.95. ConclusionThe history of drug allergy， pre-treatment ANC， PLT， CD3+HLA-DR+ T cell levels， and proliferation of nucleated cells in bone marrow before treatment are predictive factors for the efficacy of Yiqi Yangxue prescription combined with western medicine in treating AA in non-elderly adults. This therapy tends to be more effective for the patients with no history of drug allergy， higher ANC and PLT levels before treatment， especially those with ANC≥1.6×109/L， PLT≥25×109/L， and higher CD3+ HLA-DR+T cell levels and the more active proliferation of nucleated cells in bone marrow before treatment.

Resting-state electroencephalogram relevance state recognition of Parkinson's disease based on dynamic weighted symbolic mutual information and k-means clustering / 生物医学工程学杂志

At present, the incidence of Parkinson's disease (PD) is gradually increasing. This seriously affects the quality of life of patients, and the burden of diagnosis and treatment is increasing. However, the disease is difficult to intervene in early stage as early monitoring means are limited. Aiming to find an effective biomarker of PD, this work extracted correlation between each pair of electroencephalogram (EEG) channels for each frequency band using weighted symbolic mutual information and k-means clustering. The results showed that State1 of Beta frequency band ( P = 0.034) and State5 of Gamma frequency band ( P = 0.010) could be used to differentiate health controls and off-medication Parkinson's disease patients. These findings indicated that there were significant differences in the resting channel-wise correlation states between PD patients and healthy subjects. However, no significant differences were found between PD-on and PD-off patients, and between PD-on patients and healthy controls. This may provide a clinical diagnosis reference for Parkinson's disease.

Clinical Effect of Bushen Shengxue Prescription on Chronic Aplastic Anemia and Its Effect on T Cell Subsets and Expression of T-bet and GATA3 / 中国实验方剂学杂志

ObjectiveTo investigate the efficacy of Bushen Shengxue prescription and Yiqi Yangxue prescription in the treatment of chronic aplastic anemia and the effect on T cell subsets and the expression of T-box expressed in T cells （T-bet） and GATA binding protein 3 （GATA3）. MethodA total of 585 patients with chronic aplastic anemia who were treated in 19 hospitals in China from May 2018 to June 2021 were enrolled. With the prospective， double-blind and randomized control methods， the patients were randomized into three groups： kidney deficiency group， Qi and blood deficiency group， and control group. The three groups were respectively treated with Bushen Shengxue prescription granule， Yiqi Yangxue prescription granule， and Placebo （half the dose of Bushen Shengxue formula granules）. In addition， all of them were given oral cyclosporin and androgen. The treatment lasted 6 months， with 3 months as a course. The blood routine indexes， T cell subsets， and fusion genes T-bet and GATA3 before and after treatment were analyzed， and the safety indexes were monitored. ResultDuring the observation， a total of 75 cases dropped out and 18 were rejected. Finally， 161 cases in the kidney deficiency group， 164 in the Qi and blood deficiency group， and 167 in the control group were included. After 6 months of treatment， the total effective rate was 98.8% （159/161） in the kidney deficiency group， which was higher than the 79.9% （131/164） in the Qi and blood deficiency group （χ2=30.135， P<0.01） and the 61.7% （103/167） in the control group （χ2=70.126， P<0.01）. The total effective rate was higher in the Qi and blood deficiency group than in the control group （χ2=13.232， P<0.01）. After treatment， the hemoglobin （HGB） content increased significantly in three groups （P<0.05） as compared with that before treatment， particularly the kidney deficiency group （P<0.01）. After treatment， the white blood cell （WBC） count and platelet （PLT） count in the kidney deficiency group and the control group increased compared with those in the Qi and blood deficiency group （P<0.01）. There was no specific difference in neutrophils （ANC） after treatment among the three groups. At the same time point， the level of T helper type 1 （Th1） cells， Th1/Th2 ratio （P<0.05）， level of CD4+， and CD4+/CD8+ ratio （P<0.05） were significantly low in the kidney deficiency group among three groups. There was no significant difference in CD19-， HLA/DR+， and CD25+ between the kidney deficiency group and the other two groups， but the T-bet of the kidney deficiency group and the control group was lower than that of the Qi and blood deficiency group （P<0.05）. ConclusionBushen Shengxue prescription exerts therapeutic effect on the aplastic anemia by improving the immunoregulatory mechanism， inhibiting the activity of immune system， modulating T cell subsets， suppressing Th1 and CD4+， and promoting bone marrow hematopoiesis. Moreover， it is safe with little side effects， which is worthy of further promotion.

Four Oral Chinese Patent Medicines for Treatment of Functional Dyspepsia： A Rapid Health Technology Assessment / 中国实验方剂学杂志

ObjectiveTo evaluate the safety， efficacy， and economy of the four Chinese patent medicines （CPMs）， including Simotang oral liquid， Liuwei Anxiao capsule， Baohe pill， and Jianwei Xiaoshi oral liquid in the treatment of functional dyspepsia （FD） by a rapid health technology assessment （RHTA）， thus providing evidence support for clinical decision making. MethodChina National Knowledge Infrastructure （CNKI）， WanFang Database， VIP Chinese Technology Periodical Database （VIP）， China Biology Medicine disc （CBMdisc）， PubMed， EMBASE， Cochrane Library， and Web of Science were searched by computer from inception to March 2022. After literature screening， data extraction， and quality evaluation， the descriptive analysis of the results combined with visual charts was performed. Nineteen studies were included， involving 18 randomized controlled trials （RCTs） and 1 Meta-analysis. Neither economic studies nor health technology assessment （HTA） reports were retrieved. ResultThe four CPMs were safe and effective in the treatment of FD， but economic research was lacking. Among them， Simotang oral liquid could be used for children with FD and FD caused by qi and food stagnation， liver and spleen disharmony， and liver and spleen stagnation. Liuwei Anxiao capsule could be used for adult patients with FD caused by food stagnation. Baohe pill could be used for the elderly with FD. Jianwei Xiaoshi oral liquid could be used for children with FD caused by spleen and stomach weakness. ConclusionThe four CPMs have their advantages in the treatment of FD. Among them， the clinical universality of Simotang oral liquid is higher. However， the quality of clinical evidence is generally low， and comparative analysis among drug dosage forms is lacking. In the future， it is necessary to improve， apply， and promote RHTA for rapid evidence production while carrying out a more standardized and scientific evidence-based demonstration of the comprehensive clinical efficacy of CPMs.

Clinical Evidence of Treatment of Constipation with Oral Chinese Patent Medicine： A Scoping Review / 中国实验方剂学杂志

This study systematically and comprehensively sorted out the application status of Chinese patent medicines for the treatment of constipation in the clinic， to provide scientific evidence for future research directions and clinical drug use in this field. Based on the method of scoping review， the Chinese patent medicines for the treatment of constipation were retrieved from three drug lists to obtain the medicines that needed to be evaluated. A comprehensive and systematic search was carried out on the included studies on the treatment of constipation by Chinese patent medicines through eight Chinese and English databases， and the included studies were integrated and analyzed. The results were displayed in combination with charts. Thirty-four Chinese patent medicines and 118 studies were included in this study. According to the efficacies， Chinese patent medicines were divided into 4 categories， namely eliminating accumulation， purging fire， promoting Qi， and moistening bowels， involving 125 Chinese medicines. The overall attention of constipation research is on the rise. Marenwan （granules or soft capsules） gained the highest attention， with 42 studies， followed by Qirong Runchang oral liquid， with 21 studies， and Biantong tablets （capsules）， with 19 studies. There are 10 studies on Congrong Tongbian oral liquid. Seventeen Chinese patent medicines had no corresponding clinical research. There were 8 study design types， and all drugs were mainly randomized controlled trials except Danggui Longhui pill. Among the intervention types， the comparison between Chinese patent medicines and western medicines was the most. The highest outcome indicators were efficacy， safety evaluation， and main symptoms or scores， and there was a lack of a unified core outcome indicator set. There were few studies on adverse reactions and the economy. Only 11.86% of the studies were funded. Clinically， Chinese patent medicines are widely used in the treatment of constipation， and the amount of related research shows an increasing trend. However， some Chinese patent medicines lack corresponding clinical evidence， and the published research has problems such as unrigorous design， ununified criteria for efficacy evaluation， lack of comprehensive evidence studies， and insufficient funds. It is hoped that more investment will be made in this field in the future， and more attention will be paid to drugs with relatively blank research and constipation syndromes with few treatments. Comprehensive evidence studies such as systematic reviews should be carried out actively. And the study design should be standardized to provide reliable evidence for the treatment of constipation with Chinese patent medicines.

Receptor-mediated targeted drug delivery systems for treatment of inflammatory bowel disease: Opportunities and emerging strategies

Inflammatory bowel disease (IBD) is a chronic intestinal disease with painful clinical manifestations and high risks of cancerization. With no curative therapy for IBD at present, the development of effective therapeutics is highly advocated. Drug delivery systems have been extensively studied to transmit therapeutics to inflamed colon sites through the enhanced permeability and retention (EPR) effect caused by the inflammation. However, the drug still could not achieve effective concentration value that merely utilized on EPR effect and display better therapeutic efficacy in the inflamed region because of nontargeted drug release. Substantial researches have shown that some specific receptors and cell adhesion molecules highly expresses on the surface of colonic endothelial and/or immune cells when IBD occurs, ligand-modified drug delivery systems targeting such receptors and cell adhesion molecules can specifically deliver drug into inflamed sites and obtain great curative effects. This review introduces the overexpressed receptors and cell adhesion molecules in inflamed colon sites and retrospects the drug delivery systems functionalized by related ligands. Finally, challenges and future directions in this field are presented to advance the development of the receptor-mediated targeted drug delivery systems for the therapy of IBD.

Objective To investigate the clinical effects of Qinghuang powder, low-intensity chemotherapy and Qinghuang powder alternated with low-intensity chemotherapy in the treatment of elderly acute myeloid leukemia patients progressed from myelodysplastic syndromes (MDS-AML). Methods A total of 32 elderly patients with MDS-AML treated in Xiyuan Hospital, China Academy of Chinese Medical Sciences from January 2014 to December 2017 were retrospectively analyzed. Of them, 12 patients received Qinghuang powder (Qinghuang powder group), 6 patients received Qinghuang powder alternated with low-intensity chemotherapy (alternating group), and 14 patients received low-intensity chemotherapy (low-intensity chemotherapy group), based on the real world of patient's voluntary choice of treatment. The efficacy and adverse reactions in the 3 groups were observed. Results The overall response number of Qinghuang powder, alternating, and low-intensity chemotherapy groups were 2, 2 and 4 cases, respectively, there was no significant difference among the 3 groups (P＞ 0.05). The median overall survival time of 3 groups were 14, 12 and 8 months, respectively, there was no significant difference among the 3 groups (P＞ 0.05). Two cases in Qinghuang powder group presented with gastrointestinal reactions; 3 cases in alternating group with myelosuppression, 2 cases with liver function damage, and 2 cases with gastrointestinal reaction; 11 cases in low-intensity chemotherapy group presented with bone marrow suppression, 3 cases with liver function damage, 7 cases with gastrointestinal reactions, and 2 cases with myocardial enzyme changes. The incidences of myelosuppression, liver function damage and myocardial enzyme changes in Qinghuang powder group were lower than those in the alternating group and low-intensity chemotherapy group. Conclusion The efficacy of Qinghuang powder or Qinghuang powder alternated with low-intensity chemotherapy for the treatment of elderly MDS-AML is not worse than the low-intensity chemotherapy, furthermore Qinghuang powder or Qinghuang powder alternated with low-intensity chemotherapy has fewer adverse reactions and better tolerance.

Progress of clonal hematopoiesis of indeterminate potential / 白血病·淋巴瘤

Clonal hematopoiesis is a common aging_associated biological state. The incidence of malignant neoplasms for the patients with clonal hematopoiesis of indeterminate potential (CHIP) is 0.5%-1% every year. Potential factors of clonal progression in hematopoietic cells have been summarized, including disordered endogenous immunity caused by the augmentation of proliferative pressure, chromosomal instability caused by telomeres short; the amplification of clonal stem cells, acquisition of new mutations, and aging_associated changes in hematopoietic stem cells, including altered DNA damage response, an altered transcriptional program and epigenetic alterations while failing to support healthy hematopoiesis. CHIP is a vascular risk factor driven by interactions between clonal monocytes_macrophages and the endothelium, as well as a neoplastic progression risk factor driven by the acquisition of additional somatic mutations in the context of many other influences on hematopoiesis and clonal balance. Strategies to reduce the clonal burden associated with CHIP and to inhibit the key inflammatory pathways leading to atherosclerosis could improve the prognosis of the patients.

Progress of gene mutations and prognostic models in myelodysplastic syndromes / 白血病·淋巴瘤

Myelodysplastic syndromes (MDS) are clonal disorders characterized by the accumulation of complex genomic abnormalities that defined disease phenotype,prognosis,and the risk of transformation to acute myeloid leukemia.The clinical manifestations and prognosis of patients with different phenotypes arevary different,and the overall survival varies from several months to several years.Prognostic scoring systems are important staging tools that aided physicians in their treatment recommendations and decision-making and could help patients understand their disease trajectory and expectations.These models and others use mainly clinical variables that are obtained from bone marrow biopsy and peripheral blood measurements.Adding gene mutation data into current models might improve the total predictive power.The search for an optimal way to merge the clinical and genomic data in a sophisticated and highly accurate model remains a work in progress.A comprehensive geno-clinical model that could translate the use of genomic data into clinical practice would finally be established.This paper mainly introduces the progress of the gene mutations and prognosis models of MDS in the 60th American Society of Hematology (ASH) Annual Meetings were reviewed.

Progress of gene mutation patterns and targeted therapy in myelodysplastic syndromes / 白血病·淋巴瘤

The myelodysplastic syndromes (MDS) are collectively the most common myeloid neoplasms,and the clonal hematopoiesis presented in MDS results in bone marrow failure.An understanding of the MDS gene mutation profile can help to understand the biological significance of MDS and can be used for early diagnosis of disease,precise risk stratification,interpretation of pathogenesis,and improvement of treatment options.As the pathological features of MDS are gradually elucidated,individualized and effective treatment options are improved,and the targeted drug therapy may improve the prognosis of MDS patients.This article introduces the progress of MDS gene mutations and targeted therapy in the 60th American Society of Hematology (ASH) Annual Meeting.
