ABSTRACT
OBJECTIVE@#To evaluate the efficacy and safety of Pai-Neng-Da Capsule (, panaxadiol saponins component, PNDC) in combination with the cyclosporine and androgen for patients with chronic aplastic anemia (CAA).@*METHODS@#A total of 79 CAA patients was randomly divided into 2 groups by a random number table, including PCA group [43 cases, orally PNDC 320 mg/d plus cyclosporine 5 mg/(kg·d) plus andriol 80 mg/d] and CA group [36 cases, orally cyclosporine 5 mg/(kg·d) plus andriol 160 mg/d]. All patients were treated and followed-up for 6 treatment courses over 24 weeks. The complete blood counts, score of Chinese medical (CM) symptoms were assessed and urine routine, electrocardiogram, hepatic and renal function were observed for safety evaluation. Female masculinization rating scale was established according to the actual clinical manifestations to evaluate the accurate degree of masculinization in female CAA patients treated by andriol.@*RESULTS@#The effective rates were 88.1% (37/42) in the PCA group and 77.8% (28/36) in the CA group based on the standard for the therapeutic efficacy evaluation of hematopathy. There was no significant difference in the white blood cell (WBC) counts, platelet counts and hemoglobin concentration of peripheral blood between two groups after 6 months treatment. The masculinization score of female patient in the PCA group was significantly lower than the CA group (P<0.05). The mild abdominal distention was observed in 1 cases in the PCA group. In CA group, the abnormalities in the hepatic function developed in 2 cases and the renal disfunction was found in 1 case.@*CONCLUSION@#The PNDC possesses certain curative effects in the treatment of CAA without obvious side-effects and can partially replace andriol thereby to reduce the degree of masculinization [Registried at Chinese Clinical Trial Registry (ChicTR1900028153)].

Aberrant regulation of DNA methylation plays a crucial causative role in haematological malignancies (HMs). Targeted therapy, aiming for DNA methylation, is an effective mainstay of modern medicine; however, many issues remain to be addressed. The progress of epigenetic studies and the proposed theory of "state-target medicine" have provided conditions to form a new treatment paradigm that combines the "body state adjustment" of CM with targeted therapy. We discussed the correlation between Chinese medicine (CM) syndromes/states and DNA methylation in this paper. Additionally, the latest research findings on the intervention and regulation of DNA methylation in HMs, including the core targets, therapy status, CM compounds and active components of the Chinese materia medica were concisely summarized to establish a theoretical foundation of "state-target synchronous conditioning" pattern of integrative medicine for HMs, simultaneously leading a new perspective in clinical diagnosis and therapy.

Objective:To explore the effects of anti-microbial compound （T1） from<italic> Bacillus </italic>（Phylum Firmicutes） and anti-microbial compound （T2） from <italic>Pseudomonas</italic> and <italic>Rhizobium</italic>， two growth-promoting agents， on the physiological characteristics and growth of <italic>Fritillaria przewalskii</italic>， in order to lay a foundation for the development of functional microbial agents and the promotion of ecological planting. Method:The endophytic bacteria of <italic>F. przewalskii</italic> were isolated and identified using conventional methods. The leaves of three-year-old <italic>F. przewalskii</italic> were sprayed with T1 and T2， followed by yield determination. The enzyme activities and physiological and biochemical indexes in the plant and microorganisms were measured using the corresponding assay kits， and the contents of related hormones by liquid chromatography-mass spectrometry （LC-MS）. Result:The isolated endophytic bacteria were classified into Firmicutes，Proteobacteria， and Actinomycetes. The activities of superoxide dismutase（SOD） and peroxidase（POD） and auxin content after T2 treatment were significantly higher than those after T1 treatment， while the contents of siderophore，salicylic acid， and gibberellin were lower. Compared with the blank （CK） group， T1 and T2 increased the contents of endogenous gibberellin，cytokinin， and auxin in <italic>F. przewalskii</italic> leaves，but did not significantly change jasmonic acid and abscisic acid. T1 promoted the accumulation of endogenous salicylic acid in <italic>F. przewalskii</italic> leaves， but there was no significant change after T2 treatment. Compared with CK，T1 and T2 enhanced the activities of SOD， POD， and catalase （CAT） and decreased the content of malondialdehyde. T2 promoted the accumulation of hydrogen peroxide in <italic>F. przewalskii</italic> leaves， but no significant difference was observed after T1 treatment. Compared with CK，both T1 and T2 increased chlorophyll，average iron content in rhizosphere soil， and 100-plant weight. Conclusion:T1 and T2 treatments help to increase the yield，and their specific mechanisms differ from each other. T1 exhibits better effect than T2.
ABSTRACT
Graft-versus-host disease (GVHD) is the most common complication after allogeneic hematopoietic stem cell transplantation, and also an important factor affecting the survival and quality of life in patients after transplantation. Currently, immunosuppressive therapy is commonly used for GVHD, but the curative effect is not ideal. How to effectively prevent and treat GVHD is one of the difficulties to be solved urgently in the field of transplantation. In this paper, we summarize the latest progress in pathogenesis, prevention and treatment of GVHD with Chinese medicine (CM). We hope it will provide ideas and methods for exploring the mechanism and establishing a new comprehensive therapy for GVHD with CM.

Hepatocellular carcinoma (HCC) is a malignant tumor with high morbidity and mortality globally. It accounts for the majority of primary liver cancer cases. Amyloid precursor protein (APP), a cell membrane protein, plays a vital role in the pathogenesis of Alzheimer’s disease, and has been found to be implicated in tumor growth and metastasis. Therefore, to understand the relationship between APP and 5-fluorouracil (5-FU) resistance in liver cancer, Cell Counting Kit-8, apoptosis and cell cycle assays, western blotting, and reverse transcription-quantitative polymerase chain reaction (qPCR) analysis were performed. The results demonstrated that APP expression in Bel7402-5-FU cells was significantly up-regulated, as compared with that in Bel7402 cells. Through successful construction of APP-silenced (siAPP) and overexpressed (OE) Bel7402 cell lines, data revealed that the Bel7402-APP751-OE cell line was insensitive, while the Bel7402-siAPP cell line was sensitive to 5-FU in comparison to the matched control group. Furthermore, APP overexpression decreased, while APP silencing increased 5-FU-induced apoptosis in Bel7402 cells. Mechanistically, APP overexpression and silencing can regulate the mitochondrial apoptotic pathway and the expression of apoptotic suppressor genes (B-cell lymphoma-2 (Bcl-2) and B-cell lymphoma-extra large (Bcl-xl)). Taken together, these results preliminarily revealed that APP overexpression contributes to the resistance of liver cancer cells to 5-FU, providing a new perspective for drug resistance.
