Bamboo charcoal affects soil properties and bacterial community in tea plantations.

Bamboo charcoal, a type of manufactured biochar, is produced by pyrolyzing bamboo residue under anoxic conditions. Its beneficial properties in absorption, catalyst support, and agricultural function have attracted significant attention; however, relatively few studies have examined its effects on the soil microbiota. In this study, we analyzed the effects of bamboo charcoal on soil physicochemical properties, enzymes, and microbial community structure in tea plantations and investigated the optimal amount of bamboo charcoal to be added to organic fertilizer.

[Technology and principle of improving solubility of Dioscoreae Rhizoma formula granules based on powder modification].

The powder modification technology was used to improve the powder properties and microstructure of Dioscoreae Rhizoma extract powder, thereby solving the problem of poor solubility of Dioscoreae Rhizoma formula granules. The influence of modifier dosage and grinding time on the solubility of Dioscoreae Rhizoma extract powder was investigated with the solubility as the evaluation index, and the optimal modification process was selected. The particle size, fluidity, specific surface area, and other powder properties of Dioscoreae Rhizoma extract powder before and after modification were compared.

Objective: To investigate the effect of other gene mutations outside the fusion gene on the first complete remission (CR) induced by one course of induction chemotherapy in patients with core binding factor-associated acute myeloid leukemia (CBF-AML).

Methods: DNA was extracted from bone marrow or peripheral blood samples of newly diagnosed CBF-AML patients admitted to the Hematology Department of the Second Hospital of Shanxi Medical University from January 2015 to January 2019. Next-generation sequencing was used for detection of 34 kinds of hematologic malignancy-related gene mutations in patients with CBF-AML, the effect of related gene mutations on the first complete remission (CR) rate in one course of induction chemotherapy was analyzed by combineation with clinical characteristics.

Molecular characterization of a MOSPD2 homolog in the barbel steed (Hemibarbus labeo) and its involvement in monocyte/macrophage and neutrophil migration.

Motile sperm domain containing 2 (MOSPD2) is a single-pass membrane protein to which until recently little function had been ascribed. Although its mammalian homologs have been identified, the status of the mospd2 gene in lower vertebrates is still unknown. In the present study, cDNA of the mospd2 gene of barbel steed (Hemibarbus labeo) was cloned and sequenced to characterize its potential involvement in the innate immune system of this fish.

Molecular characterization and expression analysis of IL-1β and two types of IL-1 receptor in barbel steed (Hemibarbus labeo).

Interleukin-1β (IL-1β) is a pivotal proinflammatory cytokine that plays important roles in regulating immune responses and in inducing a series of inflammatory reactions in response to infection. Recently, increasing attention has focused on the regulatory mechanisms of IL-1β activity in teleosts. In this regard, IL-1 receptor type 1 plays a crucial role in immune responses, whereas IL-1 receptor type 2 is a decoy receptor that functions as an IL-1β signaling inhibitor.

Hypolipidemic and antioxidant activities of volatile oils from fresh leaves of Michelia martini Levl.

.This study aimed to investigate the hypolipidemic and antioxidant activities of volatile oils from Michelia martini Levl. The antioxidant property of volatile oils from Michelia martini in vitro was investigated by establishment of various systems.

The impact of oral arsenic and all-trans-retinoic acid on coagulopathy in acute promyelocytic leukemia.

The aim of our study was to evaluate the impact of oral arsenic (the realgar-indigo naturalis formula, RIF) and all-trans retinoic acid (ATRA) on coagulopathy in acute promyelocytic leukemia (APL) compared with intravenous arsenic trioxide (ATO) and ATRA during induction. Mitoxantrone was added to all the patients at a dose of 1.4mg/m per day for 5-7 days.

Factors affecting the CD34 cell yields from the second donations of healthy donors: The steady-state lymphocyte count is a good predictive factor.

Background: A second allogeneic hematopoietic stem-cell transplantation and donor lymphocyte infusion using cells from the same donor is a therapeutic option in the case of stem-cell graft failure or disease relapse, but little is known about the factors associated with the CD34 cell yields from second donations.

Methods: One-hundred healthy donors who underwent a second mobilization treatment and peripheral blood stem-cell (PBSC) collection were studied. For both mobilization processes, 5 µg of granulocyte colony-stimulating factor per kg per day was administered.

Response to corticosteroids and cytotoxic drugs in a case of idiopathic hypereosinophilic syndrome with predominantly elevated eosinophils and multiple clinical manifestations.

In the present case study, a 42-year-old Chinese woman fulfilling the WHO criteria for idiopathic hypereosinophilic syndrome (IHES) who exhibited clinical manifestations of eosinophilic infiltration of multiple tissues including the lungs, heart, central and peripheral nervous system, gastrointestinal tract, spleen, liver and unexplained clinical findings is described.

[FVIII intron 22 homologous region mediated recombinations and genotyping methods of hemophilia A].

The intron 22 inversion is caused by intrachromosomal homologous recombination of the Int22h (intron 22 homologous region) repeats in opposite orientation, accounting for almost 45%-50% of all cases of severe hemophilia A. By contrast, recombinations between similarly oriented int22h repeats in the same chromosome, homologous chromosomes or chromatids may cause deletion or duplication of the intermediate region between the two int22h copies, resulting in false-positive or false-negative possibility that obscure the characterization of intron 22 inversion. The modified long distance PCR(LD-PCR) and inverse shifting PCR(IS-PCR) would distinguish all the possible int22h-mediated rearrangements.

[Powder modification technology used for the preparation of the hydrophilic decoction pieces of indigo naturalis and the modification principle].

The hydrophilicity of the normal decoction pieces (NDP) of Indigo Naturalis is not good, therefore, it is not suit for decoctions. In this paper, powder modification technology is used and some NDP and alcohol are ground together in the vibromill to prepare the hydrophilic decoction pieces (HDP) of Indigo Naturalis. Initially, the properties of NDP, ultrafine decoction pieces (UDP) and HDP are compared, the hydrophilicity of UDP was promoted slightly, that of HDP is promoted dramatically.
