[Efficacy of Activated Autologous Hematopoietic Stem Cell Transplantation in the Treatment of Acute Myeloid Leukemia].

Objective: To compare the efficacy of activated autologous bone marrow and peripheral blood hematopoietic stem cell transplantation (Auto-HSCT) and matched sibling donor allogeneic hematopoietic stem cell transplantation (MSD-HSCT) for the first complete remission of adult acute myeloid leukemia (AML-CR1).

Methods: For 86 adult patients with first complete remission of AML who underwent auto-HSCT (41 cases) and MSD-HSCT (45 cases) in our hospital from June 2012 to June 2020, the patients were treated with modified MAC ［Malflane 160 mg/(m·d), -3 days, Ara-C 2 g/(m·2), -3 days 21∶00, -2 days 9∶00, CTX 60 mg/(kg·d),-3 d, -2 d］, the stem cells were activated by IL-2 (1 000 U/ mL), IFN-α (100 U/ mL) and IFN-γ (100 U/ml). The overall survival (OS), leukemia free survival (LFS), cumulative incidence of recurrence (CIR) and non-recurrence mortality (NRM) of patients with different types of transplantation were compared.

Penicilindoles A-C, Cytotoxic Indole Diterpenes from the Mangrove-Derived Fungus Eupenicillium sp. HJ002.

Three new indole diterpenes, penicilindoles A-C (1-3), were isolated from the mangrove-derived fungus Eupenicillium sp. HJ002. Their planar structures and absolute configurations were determined by interpretation of NMR spectroscopic data, HR-ESIMS, and X-ray diffraction analysis using Cu Kα radiation.

One new cytochalasin metabolite isolated from a mangrove-derived fungus Daldinia eschscholtzii HJ001.

One new cytochalasin metabolite [11]-cytochalasa-5(6),13-diene-1,21-dione-7,18-dihydroxy-16,18-dimethyl-10-phenyl-(7S*,13E,16S*,18R*) (1), together with three known compounds (2-4) were obtained from the EtOAc extract of the endophytic fungus Daldinia eschscholtzii HJ001 isolated from the mangrove Brguiera sexangula var. rhynchopetala collected in the South China Sea. Their structures were elucidated by the detailed analysis of comprehensive spectroscopic data.

Wuzi Yanzong pill, a Chinese polyherbal formula, alleviates testicular damage in mice induced by ionizing radiation.

Background: Chinese medicine Wuzi Yanzong pill (WZYZP) was firstly documented in ancient Chinese medical works "She Sheng Zhong Miao Fang" by Shi-Che Zhang in 1550 AD. The traditional herbal formula is widely used in treating nephrasthenia lumbago, prospermia, erectile dysfunction and male sterility. The present study was to explore the effects of WZYZP on ionizing irradiation-induced testicular damage in mice.

Dihydroisocoumarins from the Mangrove-Derived Fungus Penicillium citrinum.

Three new dihydroisocoumarin penicimarins G-I (-), together with one known dihydroisocoumarin () and three known meroterpenoids (-), were obtained from a fungus isolated from the mangrove var. collected in the South China Sea. Their structures were elucidated by the detailed analysis of spectroscopic data.

[Effect of Scalp Penetration Acupuncture on the Expression of NGF in Brain Tissue around Hematoma of Intracerebral Hemorrhage Rats].

Objective To observe the effects of scalp penetration acupuncture on the expression of nerve growth factor (NGF) in brain tissue around hematoma of intracerebral hemorrhage rats. Methods To- tally 120 healthy male Wistar rats were divided into the sham-operation group, the model group, the acupunc- ture group by random digit table, 40 in each group. Rats in each group were further randomly divided into 4 time points, i.

[Prophylactic effect of TLR5 agonist flagellin on acute graft versus host disease after allogeneic hematopoietic stem cell transplantation and its mechanism].

This study was aimed to investigate the prophylactic effect of Toll like receptor (TLR)5 agonist flagellin on acute graft versus host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and its possible mechanism. The animal model with allo-HSCT aGVHD was established by using purebred mice (male mouse C57BL/6 as donor, female mouse BALB/c as recipient) with complete-unidentical major histocompatibility antigen. The recipient mice were randomly divided into 3 groups: group 1 in which mice were injected with high purity (95%) flagellin before and after allo-HSCT respectively, group 2 in which mice received allo-HSCT without injection of flagellin, group 3 in which mice were radiated alone.

The short- and medium-term results of transcatheter closure of atrial septal defect with severe pulmonary arterial hypertension.

We investigated the short-term and medium-term results in patients with pulmonary arterial hypertension (PAH) associated with atrial septal defect (ASD) undergoing transcatheter closure. Fifteen patients with severe PAH associated with ASD who underwent successful occluder implantation from 2007 to 2010 were included. Clinical, echocardiographic, and hemodynamic data were reviewed.

[Effect of bortezomib on the drug sensitivity of imatinib resistant K562/G01 cells].

Objective: To explore the effect of bortezomib (BOR) on the drug sensitivity of imatinib-resistant chronic myeloid leukemia cell line K562/G01 cell and its mechanism.

Methods: MTT assay was used to detect the inhibition effect of cell growth, flow cytometry to cell cycle, and real time-PCR to the expression of COX-2 and mdr1 mRNA.

Results: Combination of 10 and 20 nmol/L BOR with imatinib could significantly enhance the sensitivity of K562/G01 to imatinib, the reverse factor was 1.

[Diagnosis and treatment of laryngeal neuroendocrine carcinoma].

Objective: To summarize the clinical features of laryngeal neuroendocrine carcinoma (LNEC).

Methods: The clinical data of all LNEC patients hospitalized during the period of June 1988 - December 2010 were analyzed retrospectively.

Results: Among all LNEC 12 patients as confirmed by pathological examination, there were typical carcinoid (n = 1), atypical carcinoid (n = 4) (2 with cervical metastasis, 1 with paraneoplastic syndrome), small cell neuroendocrine carcinoma (n = 7) (1 with adenocarcinoma).

[Relationship between CD4(+)CD25(+) regulatory T cells, IL-2, TGF-beta and acute graft-versus host disease after allogeneic hematopoietic stem cell transplantation].

This study was aimed to investigate the relationship between CD4(+)CD25(+) regulatory T cells, IL-2, TGF-beta and acute graft-versus host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The percentage of peripheral blood CD4(+)CD25(+) Treg cells in CD4(+) T cells of 13 patients with hematological malignancies after allo-HSCT were detected by flow cytometry; serum levels IL-2 and TGF-beta in these patients were measured by ELISA. The results indicated that all the patients achieved engraftment.
