OBJECTIVETo analyze the relationship between the primary mutation at np11778 and the secondary mutations at np9804, np13708, np13730, np15257 in three Chinese pedigrees with Leber's hereditary optic neuropathy (LHON) and to detect the effects of the mutations on LHON.
METHODSThirty-seven maternal individuals from three LHON pedigrees and forty-seven normal controls were involved in this study. Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and DNA sequencing were used to detect the mutations in mitochondrial DNA (mtDNA).
RESULTSAll patients and their maternal relatives had the np11778 mtDNA primary mutation. None had the secondary mutations at np9804, np13708 and np13730 and np15257. DNA sequencing of the PCR fragment revealed six new point mutations at np13759, np13928, np13942, np15301, np15323 and np15326.
CONCLUSIONAll three Chinese pedigrees with LHON had the mtDNA11778 primary mutation. The frequency of mutation at np13759 in Chinese patients with LHON is higher than that in normal Chinese controls. These findings indicate that np13759 is a new secondary mutation of LHON in Chinese.

OBJECTIVETo explore the isolation, in vitro culture and chondrogenic differentiation of goat bone marrow mesenchymal stem cells (BMSCs).
METHODSBone marrow was harvested from a 10-month-old Chinese goat for adherent culture of the BMSCs in vitro. Flow cytometry was performed to detect the cell surface markers of the BMSCs of the fourth generation. The induction medium (containing 10% fetal bovine serum, high-glucose DMEM, 6.25 microg/ml insulin, 6.25 microg/ml transferrin, 50 microg/ml vitamin C, 100 nmol/L DXM and 10 ng/ml transforming growth factor-beta1) was then applied for chondrogenic differentiation. Cytochemical staining, RT-PCR and Western blotting were performed to detect the expressions of type II collagen and aggrecan in the cells at the time points of 0, 1, 2 and 4 weeks.
RESULTSThe goat BMSCs grow well in vitro with a high purity in the fourth generation. The expression of chondrocyte phenotypes were observed at 1, 2 and 4 weeks, which became more obvious as the culture prolonged. The mRNA and protein expression of type II collagen and aggrecan in the BMSCs increased obvious after the induction and had reached a satisfactory level by 2 weeks.
CONCLUSIONGoat BMSCs have the potential to differentiate into chondrocytes in vitro, and the results of this study provide the experimental basis for application of goat BMSCs in bone and cartilage tissue engineering in vivo.

OBJECTIVETo study the clinical outcome, adverse effect and treatment cost of homoharringtonine (HHT) in combination with all-trans retinoic acid (ATRA) and arsenic trioxide (AS2O3) for newly diagnosed with patients acute promyelocytic leukemia (APL).
METHODSClinical data of treatment of newly diagnosed patients with APL in experimental group (HHT + ATRA + AS2O3, n = 14) and control group \[Idarubicin (IDA) + ATRA + AS2O3, n = 21\] were analyzed retrospectively. The therapeutic effects, side effects and costs during induction therapy were compared between the two groups.
RESULTS(1) The complete remission (CR) rate were 92.9% (13/14) and 95.2% (20/21) in experimental group and control group, respectively. The time to achieve CR were (28.1 ± 3.8) and (31.7 ± 4.2) days, respectively (P > 0.05). The negative rate of PML-RARα fusion gene at the time of CR were 76.9% (10/13) and 75.0% (15/20), respectively, and that in CR patient at the end of the first cycle treatment were 100.0% (13/13) and 95.0% (19/20), respectively (P > 0.05). (2) 5-year overall survival (OS) rate were (92.6 ± 0.6)% and (89.9 ± 0.5)%, respectively (P > 0.05), 5-year disease free survival (DFS) rate were 100.0% and (86.8 ± 0.6)%, respectively (P > 0.05). (3) During induction therapy, the incidence of infection in experimental and control group were 23.1% (3/13), 60.0% (12/20), respectively (P < 0.05). The amount of platelet transfusion were (54.7 ± 29.6) and (76.5 ± 25.6) units, respectively (P > 0.05), and that of fresh frozen plasma were (1157.1 ± 238.4) and (1423.5 ± 324.6) ml, respectively (P > 0.05). The total medical costs (excluding HHT and IDA) in experimental and control group were (36074.9 ± 1245.6) and (50564.5 ± 3658.4)CNY, respectively (P < 0.05).
CONCLUSIONHHT in combination with ATRA and AS2O3 regimen for newly diagnosed APL has a better efficacy, a higher long-term survival rate, and a lower costs, which is one of the reasonable choice.

Objective To analyze the relationship between the brain functional alterations of patients with Cushing's disease (CD) and patients' mental symptom by applying the Evaluating Emotional Scales and task functional magnetic resonance imaging (Task fMRI).Methods Task fMRI was performed on 8 patients with diagnosed CD admitted in the Department of Endocrinology of Chinese PLA General Hospital from Nov. 2015 to Nov. 2016 and 21 healthy people with matched age, gender and education level as control. Meanwhile, Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), Positive and Negative Affective Scale (PANAS) and Cushing Quality of Life Scale (Cushing QOL) were obtained to assess the brain functions.Results Significant depression and anxiety were observed in patients with CD, and their positive affective score was substantially lower while the negative affective score was relatively higher compared with that in the controls. Task fMRI revealed that, when watching the positive pictures, the activation degree of left cerebellum and right postcentral gyrus weakened in CD patients than in the controls, and the positive correlations existed between the activation degree of left cerebellum and the 16 o'clock adrenocorticotrophic hormone (ACTH) level, and between the activation degree of right postcentral gyrus and the urinary free cortisol (UFC) level in CD patients. In contrast, when watching the negative pictures, the activation degree of left cerebellum, bilateral parahippocampal gyrus and left inferior frontal gyrus was weakened in CD patients than in the controls, and the activation degree of left cerebellum was negatively correlated to the 0 o'clock cortisol level and SAS score, but is positively correlated to the UFC level. When watching the neutral pictures, the activation degree of left cerebellum and left parahippocampal gyrus was weakened in CD patients than in the controls.Conclusions CD patients may have impaired brain function with depression and anxiety mental symptoms. By Task fMRI, it can be found that the weakened activation degree of left inferior frontal gyrus, right postcentral gyrus, bilateral parahippocampal gyrus and left cerebellum may be related to CD patients' mental symptoms.

The purpose of this study was to investigate the effects of chloroquine diphosphate on the proliferation and apoptosis of human leukemic K562 cells, and to elucidate its possible mechanism of activity. The inhibitory effect of chloroquine diphosphate with different concentrations on K562 cell proliferation was detected by MTT method. Apoptosis was measured by flow cytometry (FCM); morphological analysis of apoptosis was performed after staining with propidium iodide (PI) under fluorescence microscope; cell apoptosis was assessed by the DNA ladder shown agarose gel electrophoresis. After treatment with chloroquine diphosphate, K562 cells were stained by Rhodamine 123 to detect changes in mitochondrial transmembrane potential (DeltaPsim) by FCM. The results showed that the cell viability decreased in dose-dependent manner, following chloroquine diphosphate treatment at different concentrations (1.5625, 3.125, 6.25, 12.5, 25, 50 and 100 micromol/L) for 24, 48 and 72 hours. By FCM analysis, the significant increases of sub-G(1) were observed. DNA ladder was detected and apoptotic nuclei were observed. DeltaPsim decreased in K562 cells after chloroquine diphosphate treatment. It is concluded that the chloroquine diphosphate can inhibit the proliferation of K562 cells and induce cell apoptosis, which may relate to down-regulation of mitochondrial transmembrane potential (DeltaPsim).
