RESUMO

Erdheim-Chester disease (ECD) is a rare histiocytosis that tends to co-exist with other myeloid malignancies. Here, we use genetic and transcriptomic sequencing to delineate a case of co-occurring BRAFV600E-mutated ECD and acute myeloid leukemia (AML), followed by AML remission and relapse. The AML relapse involved the extinction of clones with KMT2A-AFDN and FLT3-ITD, and the predominance of PTPN11-mutated subclones with distinct transcriptomic features. This case report has highlighted the screening for other myeloid malignancies at the diagnosis of ECD and the clinical significance of PTPN11-mutated AML subclones that require meticulous monitoring.

RESUMO

The role and mechanisms of integrated stress response inhibitor (ISRIB) on silicosis are still not well defined. In the present study, the effects of ISRIB on cellular senescence and pulmonary fibrosis in silicosis were evaluated by RNA sequencing, micro-computed tomography, pulmonary function assessment, histological examination, and Western blot analysis. The results showed that ISRIB significantly reduced the degree of pulmonary fibrosis in mice with silicosis and reduced the expression of type I collagen, fibronectin, α-smooth muscle actin, and transforming growth factor-ß1. Both in vivo and in vitro results showed that ISRIB reversed the expression of senescence-related factors ß-galactosidase, phosphor-ataxia telangiectasia mutated, phosphor-ataxia telangiectasia and Rad3-related protein, p-p53, p21, p16, and plasminogen activator inhibitor type 1. The aforementioned results were consistent with the sequencing results. These findings implied that ISRIB might reduce the degree of pulmonary fibrosis in mice with silicosis by inhibiting the cellular senescence of alveolar epithelial cell type II.

RESUMO

Langerhans cell histiocytosis (LCH) is an inflammatory myeloid malignancy in the "L-group" histiocytosis. Mitogen-activated protein kinase (MAPK) pathway activating mutations are detectable in nearly all LCH lesions. However, the pathogenic roles of MAPK pathway activation in the development of histiocytosis are still elusive. This review will summarize research concerning the landscape and pathogenic roles of MAPK pathway mutations and related treatment opportunities in Langerhans cell histiocytosis. Video abstract.

RESUMO

Adult Langerhans cell histiocytosis (LCH) remains poorly defined. We retrospectively studied 266 newly diagnosed LCH patients to understand the clinical presentation, treatment, and prognosis of adult LCH. The median age at diagnosis was 32 years (range, 18-79 years). At the time of diagnosis, 40 patients had single lesions within a single system, 18 patients had single pulmonary LCH, 26 patients had multiple lesions within a single system (SS-m), and 182 patients had multisystem disease (MS). The most common organ involved in MS patients was the bone (69.8%), followed by the pituitary (61.5%) and lung (61.0%). BRAFV600E , BRAF deletion, and MAP2K1 mutation were detected in 38.8%, 25.4%, and 19.4% patients, respectively. BRAF deletion was found more common in patients with MS LCH compared to single-system LCH (38.5% vs 7.1%, p = .004), also in patients with liver involvement (69.2% vs 14.3%, p < .001). The estimated 3-year overall survival (OS) and event-free survival (EFS) rates were 94.4% and 54.7%, respectively, in SS-m and MS LCH. Multivariate Cox regression showed that involvement of the liver or spleen at baseline predicted poor EFS and receiving cytarabine-based therapy as a first-line treatment and age older than 30 years at diagnosis predicted favorable EFS. The involvement of risk organs and age older than 50 years predicted poor OS, and receiving cytarabine-based therapy predicted favorable OS. Therefore, BRAF deletion was correlated with MS LCH, particularly those with liver involvement. Liver or spleen involvement at baseline indicates a poor prognosis, and a cytarabine-based regimen could be considered as first-line treatment for adult LCH patients.

RESUMO

POEMS syndrome is a rare plasma cell dyscrasia with distinct lipid metabolism abnormalities at disease onset. However, the serum lipidomic characteristics in patients with POEMS syndrome were not investigated. The study performed an untargeted lipidome screening by liquid chromatography-tandem mass spectrometry (LS-MS/MS) in the pre- and post-treatment serum of 24 patients with POEMS syndrome, together with the serum of 24 paired healthy controls. Patients with POEMS syndrome had a distinct serum lipid composition compared with healthy controls, and a 3-lipid model had a predictive accuracy of 93.5% in distinguishing patients and healthy controls consisting of fatty acyl 17-oxo-20Z-hexacosenoic acid, phosphatidylcholine(16:0/18:1(9Z)) and sterol lipid 5b-pregnanediol. Four lipids including 17-oxo-20Z-hexacosenoic acid (r = 0.423, P = .040) were correlated with risk stratification, and 2 lipids including Cer(d18:0/13:0) were inversely related to serum vascular endothelial growth factor level (r=-0.465, P = .022). Eleven lipids were related to disease activity, including arachidonic acid which was inversely related and lysoPC(20:4) which was positively related. The study indicated a distinct lipid characteristic profile of patients with POEMS syndrome different from healthy controls and identified several lipids that may serve as potential diagnostic markers and monitors of therapeutic efficacy, as well as indicating potential metabolism pathways involved in the pathological process.

RESUMO

POEMS syndrome is a rare plasma cell disorder. Lenalidomide has recently emerged as a therapeutic option for POEMS syndrome. Cereblon has been identified as the direct target of lenalidomide, and high cereblon expression is associated with better response and outcome to lenalidomide therapy in multiple myeloma patients. Here, we analyzed the predictive value of cereblon, IKZF1, and IKZF3 in CD138+ selected plasma cells from forty-one newly diagnosed POEMS syndrome patients treated with lenalidomide in combination with dexamethasone at both gene and protein levels. We found that patients with high cereblon expression tended to achieve better hematologic response compared to those with low expression (p = 0.024 for gene expression; p = 0.01 for protein expression). Multivariate Cox regression analysis revealed high cereblon mRNA expression as an independent prognostic marker for longer progression-free survival (hazard ratio 0.542; 95% CI 0.337-0.871; p = 0.011). In conclusion, our results emphasized the role of cereblon mRNA expression as a unique biomarker for predicting the clinical response and outcome of lenalidomide-based therapy in newly diagnosed POEMS syndrome patients.

RESUMO

POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome is a rare plasma cell dyscrasia without standard front-line treatment. Merely, few studies have reported the responses and outcomes of bortezomib plus dexamethasone (BDex) in POEMS syndrome. In this study, a total of 69 patients (40 males) treated with front-line BDex were included. The median age at diagnosis was 50 years (range, 30-78 years). After a median of 9 cycles BDex (range 1-9), fifty-two (88.1%), thirty-two (46.4%), and forty-seven (71.2%) patients achieved the best neurologic response, hematological complete response, and serum vascular endothelial growth factor (VEGF) response, respectively. The extravascular overload, pulmonary hypertension, and renal impairment also substantially improved. No treatment-related death occurred. Two patients developed grade-1 bortezomib-induced peripheral neuropathy and were reversible after drug withdrawal. After a median follow-up of 22.5 months, the estimated 2-year overall survival and time to next treatment were 95.7% and 65.6%, respectively. In conclusion, the combination of bortezomib and dexamethasone is effective, with a high response rate and safety profile for patients with newly diagnosed POEMS syndrome.

RESUMO

To explore the clinical characteristics and outcomes in Chinese patients with type I cryoglobulinemia (CG), we retrospectively analyzed the clinical data, management, and outcomes of 45 patients diagnosed with type I CG in our hospital from January 2015 to March 2019. In our study, all type I CGs were secondary to hematologic diseases, and monoclonal gammopathy of unknown significance was the most common primary disease, accounting for 48.9% (n = 22). Additionally, B cell non-Hodgkin lymphoma, Waldenström's macroglobulinemia, and multiple myeloma accounted for 24.4% (n = 11), 20.0% (n = 9), and 6.7% (n = 3), respectively. In patients with type I CG, skin damage was the most common symptom, presenting in 57.8% of the patients, followed by peripheral neuropathy (22.2%) and renal involvement (15.6%). Treatment was initiated in 29 patients (64.4%), and the most common choice was a rituximab-based regimen in 13 patients (44.8%), followed by bortezomib-based regimen in 11 patients (37.9%). Clinical symptoms were significantly improved after treatment, and the clinical remission rate was 86.2%, including 34.5% of complete clinical remission, while the laboratory response rate was 88.9%, including 33.3% of complete response and 55.6% of partial response. The expected 1-year overall survival was 97.8%. In conclusion, for patients with multisystemic involvement, such as skin damage, kidney damage, or peripheral neuropathy, the diagnosis of type I CG should be considered, and the underlying disease needs to be explored. Symptoms and primary diseases should be taken into consideration before choosing initial management.

RESUMO

Noni is a dry and mature fruit of Morinda citrifolia, which is widely distributed in the islands in the southern Pacific Ocean and the Indochina Peninsula in Asia. It is edible and has been used as a natural medicine for thousands of years. At present, Noni has been legally introduced into China, but there is no clear standard of traditional Chinese medicine properties and clinical application of traditional Chinese medicine, which greatly limits the application of compatibility with traditional Chinese medicine in China. This article appllied our pioneering modern research technology of new herbal medicine outside of China, theoretically studied the traditional Chinese medicine properties of Noni, and scientifically guided the reasonable compatibility and application of Noni with traditional Chinese medicine. The Web of Science and PubMed databases were selected to access the literatures on Noni. The retrieval time was August 1, 2018, with Noni or Morinda citrifolia as the search term. A total of 862 articles were retrieved. By reading the titles and abstracts of the articles, in addition to repetitive and irrelevant literature, 251 scientific research literatures with reasonable design and high credibility were selected, including 25 clinical trials, 94 pharmacological experiments, and 51 chemical composition literatures. Through analysis of scientific research literatures, led by clinical experiments, supported by pharmacological experiments, combined with the research progress of chemical components, the medicinal properties were studied under the guidance of traditional Chinese medicine theory. The Chinese medicine property of Noni is flat, with acid and sweet flavor.The channel tropisms of Noni included kidney, liver and spleen. The function of Noni included tonifying kindey and liver, strengthening tendon and bone, yiqi yangyin. The clinical application of Noni is used for liver and kidney deficiency, waist and knee weakness, weak muscles and bones; Qi and Yin deficiency, tiredness and thirst. Taken as fruit pulp or dry powder, the equivalent of dried product is 1-4 g. Noni is also distributed in Taiwan, Hainan in China. Hainan, Yunnan have been cultivated and introduced. Give Noni a clear Chinese medicine property, and lay a theoretical foundation for the compatibility of Noni with traditional Chinese medicine, which can enrich the Chinese medicine resources and promote the development of Chinese medicine.

RESUMO

Epimedii Folium,a commonly used traditional Chinese medicine,has the effect of tonifying kidney Yang,strengthening bones and treating rheumatism. However,in recent years,the number of reports on adverse reactions of Epimedii Folium and its Chinese patent medicines such as Xianling Gubao Capsules and Zhuanggu Guanjie Pills has been gradually increased,and the toxicity of Epimedii Folium has attracted more and more attention. In this article,the ancient and modern literature on Epimedii Folium was traced through a comprehensive and systematic literature analysis method. According to the 2015 edition of the Chinese Pharmacopoeia,Epimedii Folium refers to the dried leaves of Epimedii Folium brevicomu,E. sugittutum,E. pubescens or E. koreuuum. The Chinese Pharmacopoeia also includes E. wushanense of Wushan Epimedium,which is the same plant variety as Epimedium. The study showed that there were differences in the geographical distribution,composition and toxicity among five species of Epimedium. This paper also explained the toxicity mechanism as well as efficacy enhancing and toxicity reducing effects of Epimedii Folium,and reported its related adverse reaction cases. Through a retrospective comparative study on the toxicity of the modern Chinese patent medicines Xianling Gubao Capsules and Zhuanggu Guanjie Pills containing Epimedii Folium,it was believed that Epimedii Folium had cardiovascular system toxicity,neurotoxicity,hepatotoxicity,long-term toxicity,acute toxicity,genotoxicity and special toxicity; its safe medication factors included patient syndrome,doctor factors,drug factors,processing and compatibility factors. Meanwhile,strategies were proposed to improve patient safety medication awareness,standardize Epimedii Folium varieties and quality supervision,and the toxicity of Epimedii Folium was studied,hoping to draw attention from scholars to the safety of Epimedii Folium,improve the safe use of Epimedii Folium,and prevent adverse reactions.

RESUMO

Menopausal women appear lipid metabolism disorder with the ovarian function decline and the estrogen levels decreased. Modern clinical usually use estrogen replacement therapy and with long time application with lots of side effect appear. Traditional Chinese medicine has more secure and effective methords,using warming Yang drugs and methods. And the previous study proves the Chinese medicine Astragali Complanati Semen water extraction has a good role in regulation of blood lipids. Because of the liver is the most important organ on regulating metabolism, therefore this study aimed to evaluate the effects of total flavonoids in Astragali Complanati Semen(TFS)on liverlipid level and ERα expressionon liver in hyperlipidemia rats with kidney-Yang deficiency pattern to explore the substance basis and mechanism of Astragali Complanati Semen in regulate lipid effect and clarify traditional Chinese medicine advantages and features. This experiment uses hyperlipidemia rats with kidney-Yang deficiency pattern with bilateral ovariectomized and fed with high fat diet for 6 weeks. And rats of sham operation group and model group rats were intragastrilly(ig) with saline, estrogen group were intragastrilly with estrogen(0.2 mg·kg⁻¹). And three TFS group were intragastrilly with TFS at dose 28.5, 57, 114 mg·kg⁻¹ for 8 weeks. At the same time, TC, TG, LDL-C,HDL-C liver weight, liver index, uterine weight, uterine index, serum estrogen level, FSH levels and liver pathology, liver estrogen receptor expression were detected, weighting and calculating their organ index. The experimental results compared with the model group, TFS 114 mg·kg⁻¹ decreased the level of liver TG (P<0.05), TC (P<0.001) and LDL-C (P<0.001) and increased the level of HDL-C (P<0.05). Compared with the model group, estrogen group increased the level of blood serum (P<0.001) and decreased the level of FSH (P<0.001). In addition, compared with sham operation group,model group decreased the protein expression of ERα(P<0.01). Compared with the model group, estrogen group increased the protein expression of ERα significantly(P<0.001).TFS mid-dose group and TFS high-dose group is increased the protein expression of ERα(P<0.01, P<0.001).In a conclusion,Flavonoids is the main active ingredient of Astragali Complanati Semen. The mechanism of it maybe is enhancing the estrogen receptor sensitivity or the number of estrogen receptors, amplifying the signal after the receptor conduction, which could result in lipid-lowering effect.

RESUMO

Through the comprehensive and systematic research of domestic and overseas literature and information, we studied ancient original records on Aconiti Kusnezoffii Radix and its toxicity, analyzed related adverse cases and the animal toxicity experiments in recent years, then systematically analyzed the safety of Aconitum and its preparations, and finally we summarized the clinical characteristics and potential risk factors related to the safety of Aconitum. A report on adverse events of Aconitum in 76 patients with myocardial damage and renal damage accounting for 53.9% and 42.1% respectively, indicated that the safety problems of Aconitum may be related to heart toxicity and liver-kidney toxicity. Aconitum had complex compositions, and based on the animal experiments, Aconitum decoction had the highest toxicity at 2 h, and it reduced significantly at 4 h, which showed that the toxic components mainly depend on the hydrolysis or the decomposition degree of diester diterpenoid alkaloids. According to the toxicity study, Aconitum toxicity might occur in cardiovascular system, nervous system, kidney, embryo, reproductive system, and it was contraindicated in pregnant women. So far, specific antidote for aconitine poisoning is still a blank. The key for treatment is to correct arrhythmia timely and effectively, maintain stable vital signs, and meanwhile, give gastric lavage, intravenous fluid infusion and other therapies. So we suggest that the basic study for Aconitum toxicology should be strengthened, and the pharmacology and mechanism of toxicity, as well as the mechanism of processing for raising efficiency and reducing toxicity, should be further clarified to determine the quantity-effect relationship and eliminate safety hazards in using Aconitum.

RESUMO

To evaluate the effectiveness and safety of Xinling Wan on patients with stable angina pectoris, a randomized, double-blinded, placebo parallel-controlled, multicenter clinical trial was conducted. A total of 232 subjects were enrolled and randomly divided into experiment group and placebo group. The experiment group was treated with Xinling Wan (two pills each time, three times daily) for 4 weeks, and the placebo group was treated with placebo. The effectiveness evaluation showed that Xinling Wan could significantly increase the total duration of treadmill exercise among patients with stable angina pectoris. FAS analysis showed that the difference value of the total exercise duration was between experiment group (72.11±139.32) s and placebo group (31.25±108.32) s. Xinling Wan could remarkably increase the total effective rate of angina pectoris symptom score, and the analysis showed that the total effective rate was 78.95% in experiment group and 42.61% in placebo group. The reduction of nitroglycerin dose was (2.45±2.41) tablets in experiment group and (0.50±2.24) tablets in placebo group on the basis of FAS analysis. The decrease of symptom integral was (4.68±3.49) in experiment group and (3.19±3.31) in placebo group based on FAS analysis. Besides, Xinling Wan could decrease the weekly attack time and the duration of angina pectoris. PPS analysis results were similar to those of FAS analysis. In conclusion, Xinling Wan has an obvious therapeutic effect in treating stable angina pectoris, with a good safety and a low incidence of adverse event and adverse reaction in experiment group.

RESUMO

In this study, the authors reviewed domestic and foreign literatures, conducted the textual research on origin and development of Cassia Semen, studied records in ancient books and ancient and modern literatures, clinical adverse reactions and relevant experimental studies in recent years, and summarized the clinical features and influencing factors related to the safety of Cassiae Semen. According to the findings,Cassia Semen's safety risks are mainly liver and kidney system damages, with the main clinical features of fatigue, anorexia, disgusting of oil, yellow urine and gray stool; digestive system injury, with the main clinical features of diarrhea, abdominal distension, nausea and loose stool; reproductive system damage, with the main clinical features of vaginal bleeding. Allergic reactions and clinical adverse events, with the main clinical features for numb mouth, itching skin, nausea and vomiting, diarrhea, wheezing and lip cyanosis were also reported. The toxicological studies on toxic components of Cassiae Semen obtusifolia were carried out through acute toxicity test, subacute toxicity test, subchronic toxicity test and chronic toxicity test. Risk factors might include patients, compatibility and physicians. Physicians should strictly abide by the medication requirements in the Pharmacopoeia, pay attention to rational compatibility, appropriate dosage,correct usage and appropriate processing, control the dosage below 15 g to avoid excessive intake, strictly control the course of treatment to avoid accumulated poisoning caused by long-term administration. At the same time, clinicians should pay attention to the latest research progress, update the knowledge structure, quickly find the latest and useful materials from clinical practice, scientific research and drug information and other literatures, make evaluation and judgment for the materials, establish a traditional Chinese medicine intelligence information library, and strengthen the control over adverse effects with a pre-warning consciousness. The authors suggested standardizing clinical medication of Cassiae Semen, and avoiding misuse or excessive use; clinicians should prescribe it in strict accordance with there commended usage and dosage in the Pharmacopoeia, and focus on the safety signal accumulation in clinic, while strengthening studies for toxic substance basis and toxicity mechanism, in order to give full play to Cassiae Semen's clinical efficacy and reduce its adverse reactions.

RESUMO

Through a systematic and comprehensive study of domestic and foreign literatures and information, this study aims to trace the herbal origin and the toxicity recorded in ancient and current documents, analyze the safety case reports of Psoralea corylifolia and experimental studies on toxicity in recent years, and make a preliminary summary about the clinical characteristics and potential risk factors of cases related to the safety of P. corylifolia and its preparations. The study involved 84 patients in the safety case reports of P. corylifolia. The adverse events were mainly liver damage (55.95%) and light toxic contact dermatitis (38.10%), sugguesting that P. corylifolia may lead to liver damage and photo toxicity. However, reproductive toxicity and renal damage were only reported in animal studies, but not in clinical reports. Because of its complicated ingredients, the toxic components and mechanisms of P. corylifolia have not been clear at present. Therefore, the authors proposed to strictly apply P. corylifolia in clinic, use it rationally and combine it with other medications. Besides, efforts shall be made to strength the guidance for doctors, the safety monitoring of P. corylifolia and relevant preparations, and actively carry out safety-related basic and clinical studies, so as to give a better guidance to safe medication, full exert the efficacy and avoid the medication risk.

RESUMO

By retrieving domestic and foreign literatures, the authors provided a systematic review for effects of Xanthii Fructus, toxicity recorded in ancient/current literatures and relevant toxicological experience, and summarized clinical characteristics of clinical cases related to Xanthii Fructus and influencing factors. In addition to liver and kidney injuries as the major side effects of Xanthii Fructus, neurotoxicity and cardio-toxicity of Xanthii Fructus were also common clinical adverse events. However, there have been a few animal experimental studies so far. Oral administration and external application with Xanthii Fructus have often caused skin reactions, even such severe cases as exfoliative dermatitis. The authors suggested standardizing the clinical medication, avoiding to use untreated prescriptions and unprocessed herbs, ensuring the effective and safety use of Xanthii Fructus in strict accordance with the recommended dosage and usage in pharmacopeia, paying attention to the accumulation of safety signals, strengthening studies on toxic substance, toxicity mechanism, and synergy and attenuation effects.

RESUMO

Health food containing Chinese materia medica (CMM) conforms to the development demands of the age of big health and the theory of preventive treatment. In the view of health care and improvement of resisting diseases, it plays an important role in the market. It is very necessary to have further study and discussion on health food containing CMM. First of all, by comparing, analyzing and summarizing, the health food containing CMM could be defined as the health food which is qualified in security and functionality evaluation, with the traditional Chinese medicines(TCM) within TCM standards as the main raw materials, and the formulation-composition is based on the theory of TCM. It is characterized by higher safety than medicines, stronger biological activities than common food, multiple forms, abundant raw materials and integrated supervision and management. Secondly, we discussed the research and development (R&D) strategies and rules of health food containing CMM, pointing out that the core tasks of R&D include the investigation of formula, technology and the standards of quality. The fundamental principles of declaration and production include scientificity, rationality, reality and uniformity. Three key requirements (security, functionality and controllability) in the review as well as the process management of R&D and the key-points of risks control were summarized in this paper. Finally, the dynamic trends of policies and regulations related to health food containing CMM were analyzed in the view of registration, recording, raw materials and functions, and then related suggestions were proposed. Therefore, this article will be helpful in overall understanding the health food containing CMM and play a guiding role for its research and development.
