Abstract
Objective: To summarize and analyze of the clinical and genetic characteristics of children with nonmuscle myosin heavy chain 9 (MYH9)-related disease (MYH9-RD). Methods: To screen the patients who were first diagnosed as "chronic/refractory immune thrombocytopenia (ITP) " from April 2016 to May 2019 in Beijing Children's Hospital by genetic and clinical examinations, then the clinical manifestation, laboratory examination and genetics results of 7 children diagnosed with MYH9-RD were collected and summarized retrospectively. Results: Among 7 children diagnosed with MYH9-RD, 3 were males and 4 females. The age of onset was 1.25 (0.41-6.16) years. The course of disease was 2.16 (0.41-8.59) years. The automatic platelet count was (9 (5-30))×109/L. All the cases were found with giant platelets under microscope,and the manual platelet count was (70 (30-100))×109/L. Four cases had skin hemorrhage or epistaxis and 3 cases had no bleeding. All 7 patients had received first-or second-line therapy of ITP, of whom 1 case received splenic embolization, and all the treatments mentioned above were ineffective. Finally, it was confirmed that all 7 patients had heterozygous missense mutations of MYH9 gene by next generation sequencing (NGS), including 2 pedigrees and 5 sporadic cases. Four sporadic mutations occurred in N-terminal globular head domain (HD), and 1 sporadic case with p.D1424N mutations occurred in the C-terminal tail domain (TD). One of the pedigrees also had p.D1424N mutation. The other familial case had a novel variant with one missense variant p.A44D caused by the c.131C>A transition. One of the two p.R702 mutations had kidney damage, and several relatives of the new p.A44D mutations had deafness. Conclusions: In this study, the spontaneous mutations of seven MYH9-RD were common, and all patients were misdiagnosed as ITP, whereas the bleeding was mild and immunotherapy was ineffective. The suspected disease can be identified earlier by manual visual platelet volume and count, which can be confirmed by genetic testing. It is more important to monitor the development of other organs damage instead of thrombocytopenia. For cases with p.R702 mutations the doctor should be aware of kidney damage, and for the cases with novel mutations p.A44D the doctor should be aware of hearing loss.

Abstract
Accurate and stable x-ray beam position monitors (XBPMs) are key elements in obtaining the desired user beam stability in the Advanced Photon Source Upgrade. In the next-generation XBPMs for the canted-undulator front ends, where two undulator beams are separated by 1.0 mrad, the lower beam power (<10 kW) per undulator allows us to explore lower-cost solutions based on Compton scattering from a diamond placed edge-on to the x-ray beam. Because of the high peak power density of the x-ray beams, this diamond experiences high temperatures and has to be clamped to a water-cooled heat spreader using thermal interface materials (TIMs), which play a key role in reducing the temperature of the diamond. To evaluate temperature changes through the interface via thermal simulations, the thermal contact resistance (TCR) of TIMs at an interface between two solid materials under even contact pressure must be known. This paper addresses the TCR measurements of several TIMs, including gold, silver, pyrolytic graphite sheet, and 3D graphene foam. In addition, a prototype of a Compton-scattering XBPM with diamond blades was installed at APS Beamline 24-ID-A in May 2015 and has been tested. This paper presents the design of the Compton-scattering XBPM, and compares thermal simulation results obtained for the diamond blade of this XBPM by the finite element method with in situ empirical measurements obtained by using reliable infrared technology.

Abstract
Alterations of TWIST-1 expression are often seen in solid tumors and contribute to tumorigenesis and cancer progression. However, studies concerning its pathogenic role in leukemia are scarce. Our study shows that TWIST-1 is overexpressed in bone marrow mononuclear cells of patients with acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). Gain-of-function and loss-of-function analyses demonstrate that TWIST-1 promotes cell growth, colony formation and drug resistance of AML and CML cell lines. Furthermore, TWIST-1 is aberrantly highly expressed in CD34+CD38− leukemia stem cell candidates and its expression declines with differentiation. Down-modulation of TWIST-1 in myeloid leukemia CD34+ cells impairs their colony-forming capacity. Mechanistically, c-MPL, which is highly expressed in myeloid leukemia cells and associated with poor prognosis, is identified as a TWIST-1 coexpressed gene in myeloid leukemia patients and partially contributes to TWIST-1-mediated leukemogenic effects. Moreover, patients with higher TWIST-1 expression have shorter overall and event-free survival (OS and EFS) in AML. Multivariate analysis further demonstrates that TWIST-1 overexpression is a novel independent unfavourable predictor for both OS and EFS in AML. These data highlight TWIST-1 as a new candidate gene contributing to leukemogenesis of myeloid leukemia, and propose possible new avenues for improving risk and treatment stratification in AML.

Abstract
AIM Clematis terniflora DC. has been widely used as a traditional Chinese medicine for the treatment of tonsillitis, rheumatoid arthritis, and prostatitis. Despite its widespread use in China, there are currently no studies systematically examined its therapeutic effects and mechanism of action. As such, the present study was conducted to evaluate the anti-inflammatory, antinociceptive, and immunomodulatory effects of C. terniflora DC. using rodent and cellular models. METHODS The anti-inflammatory properties of the 70% ethanol eluted fraction of the 70% ethanol extract of C. terniflora DC. (EECTD) were evaluated using the xylene-induced ear swelling test, the carrageenan-induced edema model, and the cotton pellet granuloma method. Its antinociceptive activities were determined using both the acetic acid-induced writhing test and the hot plate assay. In parallel, we conducted an in vitro assay in LPS-induced RAW264.7 cells to examine the anti-inflammatory effects of EECTD and its purified form, aurantiamide acetate (AA) on inhibition of nitric oxide (NO) and prostaglandin E2 (PGE2) release. RESULTS EECTD (300mg/kg) significantly reduced the number of writhing, extended the pain response latency, and suppressed xylene-induced ear swelling. Each EECTD treatment group also had significant inhibition of cotton granulation formation in addition to reduced carrageenan-induced paw edema. EECTD was also shown to alleviate signs of inflammation in histopathological paw sections. However, it had a less noticeable effect on mouse ear swelling in the delayed type hypersensitivity test. A purified compound was isolated from EECTD and its structure was identified as AA. In vitro experimental results showed that both EECTD and AA were able to significantly inhibit the release of pro-inflammatory cytokines NO and PGE2 on LPS-induced RAW264.7 cells. CONCLUSION These results suggest that EECTD has significant anti-inflammatory and antinociceptive activities, partially related to one of the active substances identified as AA. We hypothesize that these effects are related to its ability to inhibit the production of cytokines NO and PGE2. However, further work will be needed to determine its exact mechanism of action.

Abstract
BACKGROUND The mechanisms underlying cyclin-dependent kinase 5 (Cdk5)-mediated thermal hyperalgesia induced by inflammation remain poorly understood. In the present study, we examined thermal hyperalgesia provoked by peripheral injection of complete Freund׳s adjuvant (CFA) to test for Cdk5 signaling in the spinal dorsal horns of rats through the p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway, which is known to function in mediating inflammatory pain. METHODS We induced the inflammatory pain model by plantar injection of CFA and compared the inhibitory effects of roscovitine and SB203580 on thermal hyperalgesia. We measured localization of Cdk5, p35, OX-42, and glial fibrillary acidic protein (GFAP) in the dorsal horn at 1 and 3 days after CFA injection using immunohistochemistry, and we measured protein levels of OX-42 and phosphorylated-p38 (p-p38) using Western blot analysis. Tumor necrosis factor-a (TNF-a) was measured by ELISA. RESULTS The maximum thermal hyperalgesia induced by CFA occurred at 1d following injection and decreased until 5 d. We found colocalization of the Cdk5 activator p35, the microglial marker OX-42 and p-p38 in the same microglial cells and neurons of the spinal cord at day 1 after CFA injection; however, we saw no colocalization of p35 and GFAP, a marker of activated astrocytes. The thermal hyperalgesia induced by CFA was inhibited by intrathecal administration of the Cdk5 inhibitor roscovitine and by the p38 inhibitor SB203580. Furthermore, the expression of OX-42, p-p38, and TNF-a was remarkably increased from days 1 to 5 post-CFA injection and were significantly reversed by roscovitine between 1 and 3 days. CONCLUSIONS Cdk5, an upstream regulator of p38 and TNF-a, mediates CFA-induced thermal hyperalgesia. As such, pharmacological blocking of the generation of p-p38 mediated by Cdk5 may present a novel approach for diminishing inflammatory pain.

Abstract
HSPB8 has been shown to be involved in regulation of cell proliferation and apoptosis, and it has also been found to have divergent properties in solid tumors. The purpose of this study was to investigate the expression and function of HSPB8 in hematopoietic malignancies. Expression and induced expression of HSPB8 was evaluated in hematopoietic tumor cell lines and bone marrow samples from patients with leukemia. Methylation status was investigated by methylation-specific polymerase chain reaction. The role of HSPB8 in hematopoietic malignancies was addressed by reintroducing HSPB8 expression into the K562 (leukemia) and Namalwa (lymphoma) cell lines. Expression of HSPB8 was absent in hematopoietic tumor cell lines and primary patient and normal volunteer samples. Promoter DNA methylation of HSPB8 was observed in these cells. HSPB8 expression could be restored after demethylation treatment with 5-aza-2'-deoxycytidine. Overexpression of HSPB8 reduced colony formation of both K562 and Namalwa cell lines, inhibited the cell growth of Namalwa in vitro, and suppressed tumor formation of K562 cells in vivo. The present study demonstrates that HSPB8 is silenced by DNA methylation in hematopoietic malignant and normal cells and its expression can be induced by treatment with 5-aza-2'-deoxycytidine. Overexpression of HSPB8 may have an antitumor activity in chronic myelogenous leukemia and lymphoma.

Abstract
OBJECTIVE Melanoma differentiation-associated gene-7/interleukin-24 (mda-7/IL-24) has been consistently shown to exert growth inhibitory effects on various tumor types. However, the majority of these reports were limited to solid tumors. The purpose of this study was to investigate the antitumor activity of mda-7/IL-24 and the underlying mechanism in hematopoietic malignancies. MATERIALS AND METHODS We determined the expression of mda-7/IL24 and its heterodimeric receptors in hematopoietic tumor cell lines and then stably transfected mda-7/IL-24 into K562 (leukemia) and Namalwa (lymphoma) cell lines to assess the effects of mda-7/IL-24 on cell proliferation, cell cycle, apoptosis, colony-forming ability, and tumor growth in vivo. Microarray analysis was performed to determine the genes that were differentially regulated by mda-7/IL-24 in K562 cells. RESULTS Expression of mda-7/IL-24 or its intact receptor pairs was not detected in the 11 cell lines tested. Ectopic expression of mda-7/IL-24 induced significant (p < 0.05) inhibition of cell growth and colony formation in both K562 and Namalwa cells, and the growth inhibition in K562 cells was associated with G(0)/G(1) cell-cycle arrest. Results of in vivo studies showed good correlation with in vitro inhibition of tumor cell proliferation in both the cell lines. We also showed that the increase in p21(WAF-1) and BCCIP and decrease in cdk6, smurf2, and phosphorylated pRb, which are regulators of cell-cycle progression, might account for G(0)/G(1) cell-cycle arrest in K562 cells. CONCLUSIONS The present study demonstrated for the first time the potential antitumor activity of mda-7/IL-24 in chronic myelogenous leukemia and lymphoma.

Abstract
We report the first measurements of z-dependent coherent optical transition radiation (COTR) due to electron-beam microbunching at high gains ( >10(4)) including saturation of a self-amplified spontaneous emission free-electron laser (FEL). In these experiments the fundamental wavelength was near 530 nm, and the COTR spectra exhibit the transition from simple spectra to complex spectra ( 5% spectral width) after saturation. The COTR intensity growth and angular distribution data are reported as well as the evidence for transverse spectral dependencies and an "effective" core of the beam being involved in microbunching.

Abstract
Self-amplified spontaneous emission in a free-electron laser has been proposed for the generation of very high brightness coherent x-rays. This process involves passing a high-energy, high-charge, short-pulse, low-energy-spread, and low-emittance electron beam through the periodic magnetic field of a long series of high-quality undulator magnets. The radiation produced grows exponentially in intensity until it reaches a saturation point. We report on the demonstration of self-amplified spontaneous emission gain, exponential growth, and saturation at visible (530 nanometers) and ultraviolet (385 nanometers) wavelengths. Good agreement between theory and simulation indicates that scaling to much shorter wavelengths may be possible. These results confirm the physics behind the self-amplified spontaneous emission process and forward the development of an operational x-ray free-electron laser.

Abstract
BACKGROUND Twelve genetic types of autosomal dominant hereditary ataxia have been recently identified and the genes responsible for most of them cloned. Molecular identification of the type of ataxia is important to determine the disease prevalence and its natural history in various populations. OBJECTIVES To perform molecular analysis of 75 Chinese families affected with spinocerebellar ataxia (SCA) and to evaluate the spectrum of mutations in these genes and the correlation between genotypes and phenotypes in Chinese patients. SETTING Neurogenetics Unit, China-Japan Friendship Hospital, Beijing, China. METHODS One hundred nine patients from 75 kindreds diagnosed as having autosomal dominant SCA, 16 patients with sporadic SCA or spastic paraplegia, 280 control chromosomes of the Chinese population, and 120 control chromosomes of the Sakha population were selected for this study. We conducted detailed mutational analysis by direct sequencing of polymerase chain reaction products amplified from genomic DNA. RESULTS Spinocerebellar ataxia type 1 (SCA1) was identified in 5 families with 12 studied patients. All affected family members were heterozygous for a CAG repeat expansion in the SCA1 gene containing 51 to 64 trinucleotide repeats. Normal alleles had 26 to 35 repeats. Spinocerebellar ataxia type 1 accounted for 7% of the studied Chinese families with ataxia. In addition, we determined the frequency of a single vs double CAT interruption in 120 control chromosomes of the Siberian Sakha population, which has the highest known prevalence of SCA1, and compared this with 280 control chromosomes from the Chinese populations. The results show that 64.7% of the Siberian normal alleles contain a single CAT interruption, whereas 92% of the Chinese had more than 1 interruption. CONCLUSIONS Spinocerebellar ataxia type 1 is responsible for 7% of affected families in the Chinese population. A correlation between the prevalence of SCA1 and the number of CAT interruptions in the trinucleotide chain suggests that a CAT-to-CAG substitution may have been the initial event contributing to the generation of expanded alleles and influencing relative prevalence of SCA1.

Abstract
We report the first measurements of the electron-beam microbunching z dependence in a self-amplified spontaneous-emission (SASE) free-electron laser (FEL) experiment by the observation of visible wavelength coherent transition radiation (CTR). In this case the fundamental SASE wavelength was at 537 nm, and the CTR exhibited an exponential intensity growth similar to the SASE radiation. In addition, we observed for the first time structure in the CTR angular distribution patterns that may be useful for optimizing SASE FEL performance.

Abstract
Sixteen patients from nine Chinese families with spinocerebellar ataxia type 2 (SCA2) were heterozygous for a CAG repeat expansion in the SCA2 gene containing 37 to 56 repeats, whereas the normal alleles carried 14 to 28 repeats. One or two CAA triplets within the CAG tract were seen in normal, but not in the expanded alleles. A strong inverse correlation was established between the number of CAG repeats and the age of disease onset. SCA2 accounted for 12% of the known Chinese families with spinocerebellar ataxia.

Abstract
Machado-Joseph disease (MJD) is an autosomal dominant neurodegenerative disorder associated with the expansion of a (CAG)n array in the MJD1 gene. We analyzed the sizes of the (CAG)n array using DNA samples from 61 members of four Chinese MJD families and 18 Chinese normal control subjects and confirmed that the (CAG)n array in 15 MJD chromosomes was expanded to 72-86 repeat units. There were no subjects with (CAG)n array sizes intermediate between those of normal and MJD affected groups. Meanwhile, we found a significant negative correlation between the age of onset of symptoms and (CAG)n array size. The largest (CAG)n array of 86 repeat units was in the youngest patient, whose age of onset was 5 years. The intergenerational increase in number of CAG repeat units was associated with the clinical phenomenon of anticipation.

Abstract
Methyl methanesulfonate (MMS 75 mg.kg-1)-induced unscheduled DNA synthesis (UDS) was inhibited significantly in the spermatozoa of mice injected with Poly I-C (0.05, 0.50, and 5.00 mg.kg-1) at 4 h prior to ip MMS. Radioactivity was reduced from 53 +/- 3 to 50, 45 +/- 5, and 34 +/- 6 dpm/million sperms respectively. The effects of Poly I-C were dose-dependent (r = 0.9498, P less than 0.05) in inhibition of MMS-induced UDS. The effect of serum collected from the mice injected with Poly I-C (0.50 mg.kg-1) had similar effects as that of Poly I-C. Our findings suggest that both Poly I-C alone and mouse serum induced with Poly I-C may prevent the DNA damage produced by MMS.

Abstract
The x-ray absorption cross section of argon was measured in the 1.3-3.8-nm wavelength region. To correct for the presence of higher orders in the monochromator output, a variable pressure technique is used. The results are in good agreement with semiempirical calculations and earlier measurements.
