ABSTRACT

OBJECTIVE Compound Kushen injection (CKI) is a bis-herbal formulation extracted from Kushen (Radix Sophorae Flavescentis) and Baituling (Rhizoma Heterosmilacis Japonicae). Clinically, it is used as the adjuvant treat?ment of cancer. However, with the increased application, the cases of immediate hypersensitivity reactions (IHRs) also gradually rise. In this study, we investigated the underlying mechanism(s) and active constituent(s) for CKI-induced IHRs in experimental models. METHODS T helper 2 (Th2) immunity-amplified mice were prepared by aluminum adjuvant. Anaphylactic shock was detected by measuring rectal thermometry in propranolol pretreated mice. For evaluating micro?vascular permeability, Evans blue extravasation assay was used. Platelet-activating factor (PAF), serum total IgE (tIgE) and mouse mast cell protease 1 (MMCP1) were measured by ELISA. RESULTS The obtained results showed that CKI did not elevate serum tIgE and MMCP1 after consecutive immunization for five weeks, but could induce Evans blue extravasation (local) and cause obvious hypothermia (systemic) after a single injection. Further study showed that alka?loids in Kushen, especially matrine, were responsible for CKI-induced IHRs. Mechanism study showed that various PAF receptor antagonists could significantly counter CKI-induced IHRs locally or systemically. In cell system, CKI was able to promote PAF production in a non-cell-selective manner. In cell lysate, the effect of CKI on PAF production became stron?ger and could be abolished by blocking de novo pathway. CONCLUSION In conclusion, our study identifies, for the first time, that CKI is a PAF inducer. It causes non-immunologic IHRs, rather than IgE-dependent IHRs, by promoting PAF production through de novo pathway. Alkaloids in Kushen, especially matrine, are the prime culprits for IHRs. Our find?ings may provide a potential approach for preventing and treating CKI-induced IHRs.

ABSTRACT

OBJECTIVE@#To investigate the regulation of miR-34a on HDAC1 expression and its effect on the apoptosis of acute myeloid leukemia (AML) cells.@*METHODS@#miR-34a mimics, miR-34a inhibitor and miR-34a scramble were transfected into HL-60 cells. The effects of miR-34a expression levels on proliferation and apoptosis of HL-60 cell were detected by CCK8 assay and flow cytometry respectively. The expression of HDAC1 protein was assessed by Western blot after regulating miR-34a expression, the 3'UTR of HDAC1 was cloned and ligated to construct a dual luciferase reporter vector, and then the dual luciferase reporter assay was applied to verify the target of miR-34a, the expression vector pcDNA3.1-HDAC1 was constructed, the interaction of miR-34a and HDAC1 was analyzed by reversion test.@*RESULTS@#miR-34a over-expression could inhibit the proliferation of HL-60 cells and induce their apoptosis. Bioinformatics analysis indicated that the HDAC1 was a target gene of miR-34a. Western blot indicated that miR-34a overexpression down-regulated the expression of HDAC1. Dual luciferase reporter assay and reversion test showed that miR-34a could act at the 3-UTR of HDAC1 gene to regulate its expression.@*CONCLUSION@#miR-34a promotes the apoptosis of HL-60 cells via regulating HDAC1 expression.

ABSTRACT

<p><b>BACKGROUND</b>The diagnosis of myelodysplastic syndrome (MDS), especially hypoplastic MDS, and MDS with low blast counts or normal karyotype may be problematic. This study characterized ID4 gene methylation in patients with MDS and aplastic anemia (AA).</p><p><b>METHODS</b>The methylation status of ID4 was analyzed by bisulfite sequencing polymerase chain reaction (PCR) and quantitative real-time methylation-specific PCR (MethyLight PCR) in 100 patients with MDS and 31 patients with AA.</p><p><b>RESULTS</b>The MDS group had a higher ID4 gene methylation positivity rate (22.22%) and higher methylation levels (0.21 [0-3.79]) than the AA group (P < 0.05). Furthermore, there were significant differences between the hypoplastic MDS and AA groups, the MDS with low blast count and the AA groups, and the MDS with normal karyotype and the AA groups. The combination of genetic and epigenetic markers was used in much more patients with MDS (62.5% [35/56]) than the use of genetic markers only (51.79% [29/56]).</p><p><b>CONCLUSIONS</b>These results showed that the detection of ID4 methylation positivity rates and levels could be a useful biomarker for MDS diagnosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate significance of ID4 gene mehtylation in demethylating myelodysplastic syndrome(MDS) cell Line MUTZ1 and 2 patients with MDS.</p><p><b>METHODS</b>The methylation-specific PCR (MS-PCR) and reverse transcription-PCR (RT-PCR) were applied to identify the methylation status and gene expression of ID4 gene in MDS cell line MUTZ1, a patient with aplastic anemia(AA) and a donor with normal bone marrow (NBM). RT-PCR was applied to detect the ID4 gene expression status in MUTZ1 cell line treated with decitabine at 3 different concentrations. Then bisulfite sequencing PCR (BSP) was applied to detect ID4 gene methylation status in 2 MDS parients treated with decitabine.</p><p><b>RESULTS</b>The MDS cell line MUTZ-1 displayed a complete methylation of ID4 gene promoter with little mRNA expression. Inversely, bone marrow of an AA patient and NBM showed complete unmethylation of this gene with intensity mRNA expression. With the increase of decitabine concentration, ID4 gene mRNA expression was more and more increased. After decitabine treatment, ID4 gene methylation-positive frequencies of both the 2 MDS patients were much more decreased than that of the first treatment. So, ID4 gene mRNA expression inhibited by promoter hypemethylation could be recovered by using demethylation medicine.</p><p><b>CONCLUSION</b>ID4 as a new potential anti-oncogene suggests that its methylation may become a marker for selection and assessment of therapeutic schedules in patients with MDS.</p>

ABSTRACT

DNA methylation of ID4 gene promoter occurred frequently in patients with acute leukemia and was found to be highly related to the tumor progression. Due to lack of the appropriate methylation detection methods, the relation between the quantification of ID4 methylation and the states of acute leukemia is still unclear. This study purposed to set up a methylation-specific quantitative PCR system for ID4 and investigate the specificity and sensitivity of this methylation detection. The plasmids combined with target gene as well as with internal reference were constructed, and the standard curves were set up by using above mentioned plasmids. The specificity of this detection system in cell lines was verified through techniques of MSP and quantitative MSP. The sensitivity of this detection system was verified by mixing methylation-positive and negative cell lines in varying proportions and through amplification of qualitative MSP. The results showed that the standard curves were establish successfully. The results of quantitative MS-PCR in cell lines were consistent with those of MS-PCR, and as low as 1: 10(-5) of ID4 methylation positive cells could be detected by the new methylation detection assay. In newly diagnosed acute leukemia patients, the positive rate of quantitative MSP was higher. It is concluded that a complete quantitative MSP system for ID4 methylation detection has been established and this quantitative MSP method has good specificity and high sensitivity.

ABSTRACT

The advances of treatment improved the prognosis of the patients with acute leukemia (AL) in the last decade, but the lack of general biomarker for predicting relapse in AL, which is one of the most important factors influencing the survival and prognosis. DNA methylation of ID4 gene promoter occurred frequently in patients with AL and was found to be highly related to the tumor progression. Based on the previous work of the setup of methylation-specific quantitative PCR system for ID4 gene, this study was designed to investigate the relation between the quantitative indicator of methylation density, percentage of methylation reference(PMR) value, and different disease status of AL. PMR of ID4 was detected by MS-PCR in bone marrow (BM) samples of 17 healthy persons and 54 AL patients in the status of newly diagnosis, complete remission and disease relapse. The results showed that at different disease status, PMR value in newly diagnosed group was significantly lower than that in complete remission group (P = 0.031). Among serial samples, PMR value remained very low at the status of patients with continuous complete remission (<1.5‰), and increased along with the accumulation of tumor cells at relapse. In 1 relapse case, the abnormal rise of PMR value occurred prior to morphological relapse. PMR value seemed to be related to body tumor cell load. It is concluded that the quantitative indicator of methylation density and PMR value may reflect the change of tumor cell load in acute leukemia patients. Dynamic monitoring of PMR maybe predict leukemia relapse.

ABSTRACT

Huge amount of data becomes available from the pharmaceutical manufacturing process with wide application of in- dustrial automatic control technology in traditional Chinese medicine (TCM) industry. The industrial big data thus provides golden op- portunities to better understand the manufacturing process and improve the process performance. Therefore it is important to implement data integration and management systems in TCM plants to easily collect, integrate, store, analyze, communicate and visulize the data with high efficiency. It could break the data island and discover useful information and knowledge to improve the manufacturing process performance. The key supporting technologies for TCM manufacturing and industrial big data management were introduced in this paper, with a specific focus on data mining and visualization technologies. Using historic data collected from a manufacturing plant of Shengmai injection of SZYY group, we illustrated the usefulness and discussed future prospects of data mining and visualization technologies.

ABSTRACT

A new risk analysis method based upon reliability theory was introduced in this paper for the quality risk management of Chinese medicine injection manufacturing plants. The risk events including both cause and effect ones were derived in the framework as nodes with a Bayesian network analysis approach. It thus transforms the risk analysis results from failure mode and effect analysis (FMEA) into a Bayesian network platform. With its structure and parameters determined, the network can be used to evaluate the system reliability quantitatively with probabilistic analytical appraoches. Using network analysis tools such as GeNie and AgenaRisk, we are able to find the nodes that are most critical to influence the system reliability. The importance of each node to the system can be quantitatively evaluated by calculating the effect of the node on the overall risk, and minimization plan can be determined accordingly to reduce their influences and improve the system reliability. Using the Shengmai injection manufacturing plant of SZYY Ltd as a user case, we analyzed the quality risk with both static FMEA analysis and dynamic Bayesian Network analysis. The potential risk factors for the quality of Shengmai injection manufacturing were identified with the network analysis platform. Quality assurance actions were further defined to reduce the risk and improve the product quality.

ABSTRACT

A set of central composite design experiments were designed by using four factors which were ethanol amount, ethanol concentration, refrigeration temperature and refrigeration time. The relation between these factors with the target variables of the retention rate of schizandrol A, the soluble solids content, the removal rate of fructose and the removal rate of glucose were analyzed with Bayesian networks, and ethanol amount and ethanol concentration were found as the critical process parameters. Then a network model was built with 2 inputs and 4 outputs using back propagation artificial neural networks which was optimized by genetic algorithms. The R2 and MSE from the training set were 0.983 8 and 0.001 1. The R2 and MSE from the test set were 0.975 9 and 0.001 8. The results showed that network analysis method could be used for modeling of Schisandrae Chinensis Fructus ethanol precipitation process and identify critical operating parameters.

ABSTRACT

It is the objective of this study to develop dynamic predictive model for the extraction process of red Ginseng using NIR spectroscopy. NIR spectroscopy was collected online and PLSR models were developed for total quantity of ginsenosides. The performance of NIR prediction model achieved R, RMSEC, RMSEP of 0.996 09, 0.018 9, 0.016 8, respectively. A first order dynamic mass transfer model was combined with NIR prediction of the quality indicator to predict the trajectory of the extraction process based upon the initial 3 or 4 data points. The results showed good agreement with actual measurements indicating reasonable accuracy of the predictive model. It could potentially be used for advanced predictive control of the extraction process.

ABSTRACT

It is the objective of this study to optimize the extraction process of red ginseng to minimize the unit cost of extracting effective ingredients. The relation between the target variables of total quantity of ginsenosides and first extraction time, first extraction solution amount, second extraction time, second extract solution amount were studied with Box-Behnken experimental design method. At the same we also considered the cost of extraction solution and energy usage. The objective function was set as unit cost of target (total quantity of ginsenosides or its purity) for the multi-objective optimization of extraction process. As a result, the optimal process parameters were found as first extraction time (108.7 min), first extraction solution amount folds (12), second extraction time (30 min), second extraction solution amount folds (8) to minimize the unit cost. It indicated that this approach could potentially be used to optimize industrial extraction process for manufacturing Chinese medicine.

ABSTRACT

<p><b>BACKGROUND</b>The perioperative aortic dissection (AD) rupture is a severe event after endovascular stent graft placement for treatment of type B AD. However, this life-threatening complication has not undergone systematic investigation. The aim of the study is to discuss the reasons of AD rupture after the procedure.</p><p><b>METHODS</b>The medical record data of 563 Stanford type B AD patients who received thoracic endovascular repair from 2004 to December 2011 at our institution were collected and analyzed. Double entry and consistency checking were performed with Epidata software.</p><p><b>RESULTS</b>Twelve patients died during the perioperation after thoracic endovascular repair, with an incidence of 2.1%, 66.6% were caused by aortic rupture and half of the aortic rupture deaths were caused by retrograde type A AD. In our study, 74% of the non-rupture surviving patients had the free-flow bare spring proximal stent implanted, compared with 100% of the aortic rupture patients (74% vs. 100%, P = 0.213). The aortic rupture patients are more likely to have ascending aortic diameters = 4 cm (62.5% vs. 9.0%, P = 0.032), involvement the aortic arch concavity (62% vs. 27%, P = 0.041) and have had multiple stents placed (P = 0.039).</p><p><b>CONCLUSIONS</b>Thoracic AD endovascular repair is a safe and effective treatment option for AD with relative low in-hospital mortality. AD rupture may be more common in arch stent-graft patients with an ascending aortic diameter = 4 cm and with severe dissection that needs multi-stent placement. Attention should be paid to a proximal bare spring stent that has a higher probability of inducing an AD rupture. Post balloon dilation should be performed with serious caution, particularly for the migration during dilation.</p>
