Objective To evaluate the regulatory effect of OX40 co-stimulatory signal on the expression of Foxp3 in inductive regulatory T cells (iTreg) in vitro.Method CD4+ CD25+ naive T cells were isolated from C57BL/6 mouse lymphocyte suspension by MASC CD4+ CD25+ regulatory T cell isolation kit.Inductive Tregs were generated by stimulation of naive T cells in the presence of transforming growth factor beta (TGFβ1),anti-CD3,anti-CD28 and IL-2.The regulatory effect on iTregs was shown by use of OX40 stimulation monoclonal antibody (OX86) or control antibody.Using flow cytometric analysis (FACS),we examined the antibody-based identification of Tregs surface markers CD4 and CD25,along with the intracellular activation marker FoxP3.Results The ratio of CD4+ CD25+ nTregs isolated from mouse lymphatic node was (5.0 ± 0.4)% vs.(71.8 ± 13.4)% of TGFβ1-driven iTregs.The ratio of CD4+ CD25+ Tregs was (80.0 ± 1.6) % in OX40 stimulation McAb group vs.(86.0 ± 1.4)% in control antibody group.Furthermore,the expression of Foxp3 was (59.2 ± 0.7) % in OX40 stimulation McAb group vs.(70.0 ± 0.8) % in control antibody group (P<0.05).Conclusion TGFβ1-dependent protocol may induce the conversion of naive CD4+ T cells into CD25+ Foxp3+ iTregs.OX40 stimulation can down-regulate the expression of Foxp3 in CD4+ CD25 + iTreg significantly.Thus OX40 molecular may become an attractive target in Tregs-induced transplant tolerance.Further study should be performed to increase the suppressive activity of iTregs through blockade of OX40 signal.

Objective To carry out a taxonomic identification of a strain of claviform bacteria iso-lated from prostatic fluid of a patient who suffered from chronic prostatitis, and to approach its phylogenic and biologic position. Methods We undertaked an initial identification by phenotypic characters such as morphologecal, physiological and biochemical characteristics to ascertain its phylogeny by chemical composi-tion analysis of cell wall and 16S rRNA gene sequencing and alignment. Results A club-shaped gram posi-tive rod bacillus was isolated in pure culture state. Its biochemical reactions were not active. The diamino-acid of cell wall was meso-diaminopimelic acid (meso-DAP) and it had wall chemotype Ⅳ ( contained arabi-nose, galactose and maltose ). Sequence searches of the GenBank database revealed that this strain had a highest level of 16S rDNA sequence similarity (99.4%) to C. tuberculostearicurn strain ATCC35692 with only 8 nucleotides difference. Conclusion On the basis of phenotypic and phylngenetie analysis, it is rea-sonable to assign this strain to the species C. tuberculostearicum, and this is the first isolation of C. tubercu-lostearicum from prostatic fluid home and abroad.

Objective:To investigate the effect of afatinib, a tyrosine kinase inhibitor, on the proliferation, cell cycle, and apoptosis of human breast cell lines, and compare its effects with those of gefitinib. Methods:Three human breast cell lines, MCF-7, T47D, and MDA-MB-231, were cultured as cell models. A methyl thiazolyl tetrazolium assay was utilized to measure cell viability. Flow cytometer was used to analyze the cell cycle arrest (PI staining) and apoptosis rates (Annexin-V/PI staining). The protein expression was detected by Western blot analysis. Results:The proliferation of three human breast cell lines was significantly inhibited by afatinib, and the IC50 levels of MCF-7, T47D, and MDA-MB-231 were 0.101, 0.141, and 0.887μmol/L, respectively. The G0/G1 phase cell ratio increased con-siderably 24 h after afatinib was added to T47D or MDA-MB-231. The cell apoptosis rate also increased in the two cell lines (88.9%and 58.1%). The cleavage of apoptosis pathway proteins PARP and caspase-3 was also promoted by afatinib. Phosphorylation of EGFR was significantly inhibited by afatinib in the MDA-MB-231 cell line. Finally, the inhibition effect of afatinib was stronger than that of gefi-tinib. Conclusion: Afatinib could significantly inhibit the proliferation of breast cancer cells and promote apoptosis. The effect was dose-dependent. Afatinib was a more effective tyrosine kinase inhibitor as compared with gefitinib.

OBJECTIVE:
Mitochondrial deoxyribonucleic acid (mtDNA) 8344 A>G (m.8344A>G) mutation is the common mutation associated with mitochondrial myoclonus epilepsy with ragged-red fibers (MERRF) syndrome. Herein we report a rare case with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes/MERRF/Leigh (MELAS/MERRF/Leigh) overlap syndrome caused by m.8344A>G mutation.
METHODS:
The clinical and imaging data of the patient were collected and an open muscle biopsy was carried out. We further employed molecular genetic analyses to detect mtDNA mutation in the proband and his mother. And then a clinical and neuroimaging follow-up was performed.
RESULTS:
This patient was a 25-year-old male, who developed exercise intolerance since the age of 6. At age 10, he suffered from acute episodes of hemianopia, and cranial magnetic resonance imaging (MRI) showed occipital stroke-like lesions and cranial magnetic resonance spectroscopy (MRS) revealed a lactate peak corresponding to the lesion. After that the patient presented slowly progressive psychomotor decline. He had myoclonic seizures and cerebellar ataxia since the age of 12. At age 21, he was admitted to our hospital because of confusion and cranial MRI revealed symmetrical lesions in bilateral posterior putamen, thalami and midbrain. Then repeated MRI showed progression of original lesions and new frontal multiple stroke-like lesions. Symptomatic and rehabilitation treatment relieved his condition. Follow-up cranial MRI at age 24 showed the lesions in basal ganglia and thalami diminished, and the midbrain lesions even completely vanished. Muscle pathology indicated the presence of numerous scattered ragged-red fibers (RRF), suggestive of a mitochondrial disorder. Polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) detected the m.8344A>G mutation of the MT-TK gene encoding mitochondrial transfer RNA for lysine in the patient's blood. Next generation sequencing (NGS) of the whole mitochondrial genome identified that the proportion of m.8344A>G was 90%, and no other mtDNA mutation was detected. Sanger sequencing further identified this mutation both in the proband and his mother's blood, although the mutation load was much lower in his mother's blood with approximately 10% heteroplasmy.
CONCLUSION
The present study is the first to describe a patient with m.8344A>G mutation in association with the MELAS/MERRF/Leigh overlap syndrome, which expands the phenotypic spectrum of the m.8344A>G mutation.

The temperature was set as 40 degrees C and injection volume was 5 microL. The monitoring of all analytes was achieved under the negative ionization mode with TOF-MS and TOF-MS/MS method. The twelve analytes showed good linearity (R2 > 0.9990) within the test ranges, the average recoveries were 98.0%-102%, respectively, and the RSD were less than 3.9%, respectively. The established method is simple, rapid, and sensitive, and can be used for quality control of Qili Qiangxin capsules.
