Abstract
OBJECTIVE To investigate the mechanism and clinical value of nicotinamide phosphoribosyltransferase (NAMPT) in multiple myeloma (MM). METHODS RT-qPCR and Western blot were used to detect the expression of NAMPT in MM cells and normal bone marrow mononuclear cells. The biological function of NAMPT was analyzed by cell proliferation and apoptosis assay, small interfering RNA silencing, overexpression assay and chromatin immunoprecipitation assay. RESULTS The mRNA and protein expression levels of NAMPT in MM cell lines (MM1R, MM1S, U266 and RPMI-8226) were significantly higher than those in normal bone marrow mononuclear cells (P < 0.001), and were most obvious in U266 cells. Compared with Si-NC group, the proliferation of U266 cells in Si-NAMPT group was significantly inhibited at 24, 48 and 72 h after transfection (P =0.006, P < 0.001, P =0.001), and the apoptosis rate of U266 cells was significantly increased at 48 h after transfection (P < 0.001). Compared with Flag-NC group, U266 cell proliferation in Flag-NAMPT group was significantly increased (P =0.003, P =0.002, P < 0.001), while the apoptosis rate decreased significantly at 48 h after transfection. The expression of NAMPT in U266 cells was regulated by XBP1 at transcriptional level. The proliferation rate of U266 cells with XBP1 or NAMPT stable knockout or MKC3946 pretreated with bortezomib was significantly decreased, the levels of BCL-2 mRNA and protein were also significantly decreased, while the levels of BAX mRNA and protein were significantly increased, moreover, the cleavage degree of caspase-3 significantly decreased, while caspase-3/7 activity increased dramatically (P < 0.05). CONCLUSIONS The high expression of NAMPT in MM cell line can promote MM cell proliferation and inhibit apoptosis. NAMPT is regulated by IRE1α-XBP1 signaling pathway in U266 cells. Stable knockdown of NAMPT or blocking of IRE1α-XBP1 pathway can significantly increase the sensitivity of U266 cells to bortezomib.

Abstract
Background Although observational studies have found an association between hypothyroidism and alopecia areata, the causality of this relationship remains unclear. Objectives This study aimed to investigate the genetic variants associated with hypothyroidism and their potential impact on the risk of developing alopecia areata. Methods genome-wide association study summary statistics for hypothyroidism (30,155 cases and 379,986 controls) and alopecia areata (289 cases and 211,139 controls) were obtained from the IEU OpenGwas project. The inverse variance-weighted method was used as the primary analysis method to evaluate the causality between hypothyroidism and alopecia areata, supplemented by the weighted median, MR-Egger, simple mode and weighted mode. Furthermore, the function of causal SNPs was evaluated by gene ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and protein-protein interaction networks. Result Utilizing two-sample Mendelian randomization analysis, we found that the single-nucleotide polymorphisms (SNPs) of hypothyroidism (OR = 1.40, 95% CI: 1.12-1.75, p = 3.03×10-3) significantly increased the risk of alopecia areata ( 289 cases and 211,139 controls ). KEGG pathway analysis showed that the candidate genes were mainly enriched in virion-herpesvirus, Th1 and Th2 cell differentiation, Th17 cell differentiation, T-cell receptor signaling pathway, PD-L1/PD-1 checkpoint pathway in cancer and Toll-like receptor signaling pathway. Protein-protein interaction networks results showed that CTLA4, STAT4, IL2RA, TYK2, IRF7, SH2B3, BACH2, TLR3, NOD2, and FLT3. Conclusion This study provided compelling genetic evidence supporting a causative association between hypothyroidism and alopecia areata, which could potentially inform the development of more efficacious treatment strategies for patients afflicted by alopecia areata.

Abstract
Objective: To analyze the efficacy of second-line regimens and prognostic factors in patients with first-relapsed multiple myeloma (MM) treated with bortezomib, cyclophosphamide, and dexamethasone (BCD). Methods: A retrospective cohort study. Clinical data were collected in first-relapsed MM patients after BCD treatment from three tertiary hospitals in north China from July 2009 to October 2022. Patients were classified according to the second-line regimen into the immunotherapy group, single novel agent group [either proteasome inhibitor (PI) or immunomodulatory drug (IMiD)], combination treatment group (both PI+IMiD), and traditional treatment group. Responses to second-line regimens and survival data were analyzed. The Kaplan-Meier method was used for survival analysis and the Cox proportional risk model was used for univariate and multivariate analyses. Results: A total of 217 patients were enrolled including 8.8% (19/217) in the immunotherapy group, 48.4% (105/217) in the PI/IMiD group, 29.9% (65/217) in the PI+IMiD group, and 12.9% (28/217) in the traditional treatment group. The median age was 62 years (range 31-83 years) and 56.2% (122/217) were males. The overall response rates (ORRs) in the four groups were 94.7% (18/19) vs. 56.2% (59/105) vs. 73.8% (48/65) vs. 32.1% (9/28) (χ2=24.55; P<0.001), respectively. The progression-free survival (PFS) of the second-line regimens (2ndPFS) was 17.7 vs. 9.0 vs. 9.2 vs. 4.6 months (χ2=22.74; P<0.001), respectively, among which patients in the PI/IMiD and PI+IMiD groups had comparable 2ndPFS (χ2=1.76; P=0.923). Patients with high-risk cytogenetic abnormalities (HRCAs) achieved the longest 2ndPFS of 22.0 months in the immunotherapy group (χ2=15.03; P=0.002). Multivariate analysis suggested that immunotherapy (HR=0.11, 95%CI 0.05-0.27), achievement of efficacy of partial response or better (HR=0.47, 95%CI 0.34-0.66), and non-aggressive relapse (HR=0.25, 95%CI 0.17-0.37) were independent prognostic factors of 2ndPFS. Conclusion: In this real-world study, immunotherapy was associated with a more favorable efficacy and PFS for first-relapsed MM patients after BCD treatment, with similar outcomes in patients with HRCAs.

Abstract
OBJECTIVE To study the expression level of nicotinamide phosphoribosyltransferase (NAMPT) in multiple myeloma (MM), its relationship with clinical indicators, prognosis and potential role. METHODS Immunohistochemical staining was used to detect the expression of NAMPT in bone marrow biopsies of patients with newly diagnosed multiple myeloma (NDMM) and patients with iron deficiency anemia (IDA) hospitalized during the same period. According to the median expression level of NAMPT, NDMM patients were divided into high expression group and low expression group. The correlation between NAMPT expression level and clinical baseline data was analyzed, and survival analysis was performed to evaluate the relationship between NAMPT expression level and prognosis. The GSE24080 and GSE19784 datasets were used to analyze the effect of NAMPT on the prognosis. Gene set enrichment analysis (GSEA) explored the possible mechanism of NAMPT involved in MM cell function. RESULTS The mean staining intensity of NAMPT in bone marrow tissue of 31 NDMM patients was 0.007±0.002, and that of 10 IDA patients was 0.002±0.002 (P < 0.05). The median expression level of NAMPT was 0.0041 in NDMM patients, and the mean staining intensity of high expression group and low expression group was 0.007±0.005 and 0.002±0.001, respectively (P < 0.001). There were certain differences in lactate dehydrogenase (LDH), C-reactive protein (CRP) and ISS staging between high expression group and low expression group (P < 0.001), while no significant differences in other indicators. The overall response rate (ORR) of high expression group was significantly lower than that of low expression group (P < 0.001). The median survival time of patients in high expression group was significantly shorter than that in low expression group (P =0.024). The results of bioinformatics analysis showed that the event-free survival (EFS) rate and overall survival (OS) rate of low NAMPT group were both higher than high NAMPT group (P =0.037, P =0.009), and NAMPT was an independent prognostic factor for EFS and OS (P =0.006, P =0.020). GSEA suggested that NAMPT might affect MM cell function through mTORC1 signaling pathway. CONCLUSIONS The expression level of NAMPT in bone marrow of NDMM patients is significantly higher than that of IDA patients, and the high expression of NAMPT may be correlated with late ISS stage, and high level of LDH and CRP. Patients with high expression of NAMPT have worse response to bortezomib and survival time may be shorter. NAMPT may be involved in the occurrence and development of MM through mTORC1 signaling pathway.

Abstract
Objective: To analyze the efficacy and safety of the sodium channel blockers (SCB) antiseizure medication in the treatment of focal epilepsy in infants under 6 months of age. Methods: This was a case series study. Infants with focal epilepsy with onset within 6 months of age and treated with SCB attending the Department of Neurology of Beijing Children's Hospital from June 2016 to April 2022 were collected. The clinical data, auxiliary examinations, SCB application, efficacy, adverse reactions, and prognosis were analyzed retrospectively. Patients were grouped according to type of seizure and epileptic syndrome, age of onset and etiology. Chi square test and Fisher exact test were used to analyze the differences between groups statistically. Results: A total of 118 infants were enrolled, 65 males and 53 females, with an age of epilepsy onset of 56 (4, 114) days. Developmental and epileptic encephalopathy was diagnosed in 60 infants, 39 had self-limited neonatal and (or) infantile epilepsy, and 19 had non-syndromic focal epilepsy. Application of SCB: 106 used oxcarbazepine, 2 used lacosamide, 9 switched from oxcarbazepine to lacosamide or a combination of 2 SCB, and 1 used oxcarbazepine, lacosamide, and lamotrigine successively; oxcarbazepine was the first choice in 46 cases. The age at which SCB was applied was 103 (53, 144) days. The children were followed up for 6 months to 6 years. SCB was effective in 89 cases (75.4%), including 70 cases (59.3%) who achieved seizure freedom. The seizure-free rate was higher in the focal epilepsy only group than in the group with other seizure types (64.4% (65/101) vs. 4/17, χ²=9.99, P<0.05). The responder and seizure-free rates were all higher in the group with the onset age of >3-6 months than the group >1-3 months (84.4% (38/45) vs. 62.5% (20/32), 73.3% (33/45) vs. 46.9% (15/32), χ²=4.85 and 5.58, both P<0.05). With the exception of variants in the PRRT2 gene, those with variants in sodium or potassium channels had higher responder and seizure-free rates than those with variants in other genes(86.2% (25/29) vs. 45.5% (10/22), 62.1% (18/29) vs. 22.7% (5/22), χ²=9.65 and 7.82,both P<0.05). The most common adverse event was transient hyponatremia, which happened in 66 cases (55.9%). There were 9 cases of rash, which subsided in 6 cases after discontinuing oxcarbazepine and switching to lacosamide, and 7 cases of electrocardiogram abnormalities, which improved after withdrawing oxcarbazepine and changing to lacosamide in 1 case. Conclusion: SCB are effective and tolerable in the treatment of focal epilepsy in infants under 6 months of age, with better efficacy in patients with genetic variants of the sodium or potassium channel, focal seizures only, and seizure onset >3-6 months of age.

Abstract
Multiple myeloma (MM) is a common plasma cell malignancy, accounting for the second largest hematological malignancy. Proteasome inhibitors represented by bortezomib (BTZ) have been the main treatment for patients with newly diagnosed and relapsed or refractory myeloma in nearly two decades. Although BTZ has improved the prognosis of MM patients, MM remains incurable in most patients, mainly because MM cells become resistant to BTZ. This review is to better understand the mechanism of MM resistance to BTZ and explore possible new therapeutic strategies.

Abstract
OBJECTIVE To investigate the clinical characteristics, therapeutic response and prognosis of patients with plasma cell leukemia (PCL) and improve the understanding of this disease. METHODS The clinical manifestations, laboratory tests and treatment response of 27 patients with plasma cell leukemia treated in The Second Hospital of Shanxi Medical University from December 2010 to August 2019 were analyzed retrospectively, and their clinical characteristics were summarized. Kaplan-Meier method was used for survival analysis. RESULTS There were 18 cases of primary plasma cell leukemia (pPCL) and 9 cases of secondary plasma cell leukemia (sPCL). The male to female ratio was 1.7∶1. The median age was 62 years old. The first manifestations were bone pain, fatigue, fever, splenomegaly and bleeding, and a large number of plasma cell infiltration was observed in the morphological examination of peripheral blood and bone marrow cells. 13 cases were detected by immunotyping and all of them expressed CD38/CD138. 8 cases underwent karyotype analysis, and 3 cases were normal, clonal abnormalities occurred in 5 cases. FISH detection was performed in 12 cases, of which 8 cases were abnormal. In 17 cases of bortezomib based chemotherapy, the ovevall response rate was 52.9%, which was higher than that in the non-bortezomib group, but there was no significant difference between the two groups (P =0.242). The overall median survival time of 27 patients was 6.4 months, the median progression-free survival time was 3.5 months, and the median survival time of patients with pPCL and sPCL was 8.2 months and 2.4 months, respectively, the difference between the two groups was statistically significant (P =0.031). CONCLUSION PCL is highly invasive and has diverse clinical manifestations, and is not sensitive to traditional chemotherapy. The median survival time of patients with pPCL is relatively longer than that of patients with sPCL. The chemotherapy regimen based on bortezomib improves the treatment effectiveness and prolongs the survival time of PCL patients.

Abstract
OBJECTIVE To analyze the expression level of nicotinamide phosphoribosyltransferase (NAMPT ) in bone marrow of multiple myeloma (MM) patients and its correlation with clinicopathological features, clinical efficacy and prognosis. METHODS RT-qPCR and Western blot were used to detect the expression of NAMPT mRNA and protein in bone marrow mononuclear cells from 85 newly diagnosed MM patients (including 17 relapsed MM patients) and 15 healthy donors, and explore the correlation of the expression of NAMPT gene with clinicopathological features and efficacy. Kaplan-Meier method was used to analyze the effects of NAMPT on progression-free survival (PFS) and overall survival (OS), and univariate and multivariate survival analysis were performed. RESULTS The median expression level of NAMPT mRNA in bone marrow of newly diagnosed and relapsed MM patients was significantly higher than that of healthy donors (P <0.001). The expression of NAMPT mRNA in relapsed MM patients was significantly higher than that in newly diagnosed MM patients (P <0.001), which was consistent with the expression of NAMPT protein. ISS staging, lactate dehydrogenase and C-reactive protein levels, p53 deletion and the proportion of myeloma cells were increased in high NAMPT expression group compared with low NAMPT expression group (P <0.001). Compared with complete remission group, NAMPT mRNA expression was significantly up-regulated in partial remission group, progression group and relapsed group (P <0.001). The median OS and PFS of patients in high NAMPT expression group was 27.3 and 14.9 months, respectively, which was significantly shorter than 39.1 and 27 months in low NAMPT expression group (P =0.048, P <0.001). Both univariate and multivariate analysis showed that NAMPT expression was correlated with PFS and OS. CONCLUSION The expression level of NAMPT in newly diagnosed and relapsed MM patients is significantly higher than that in normal controls, and its up-regulation is related to the adverse clinical characteristics, efficacy and prognosis of MM patients. NAMPT is an independent prognostic risk factor of MM.

Abstract
OBJECTIVE To investigate the clinical characteristics, prognostic factors and efficacy of hypomethylating agent (HMA) in patients with chronic myelomonocytic leukemia (CMML). METHODS The clinical data of 37 newly diagnosed patients with CMML was analyzed retrospectively, and their clinical characteristics and the efficacy of HMA were summarized. Kaplan-Meier and Log-rank test were used for univariate survival analysis, and Cox proportional hazards regression model was used for multivariate analysis. RESULTS The median age at diagnosis was 67 years old. Their common manifestations included fatigue, bleeding, abnormal blood routine and fever. Most patients had splenomegaly. According to FAB classification, there were 6 cases of myelodysplastic CMML and 31 cases of myeloproliferative CMML, while according to WHO classification, 8 patients belonged to CMML-0, 9 patients to CMML-1 and 20 patients to CMML-2. At the time of diagnosis, the median white blood cell count was 32.84×109/L, median hemoglobin (Hb) was 101 g/L, median platelet count was 65×109/L, median absolute monocyte count was 9.53×109//L, median absolute neutrophil count (ANC) was 11.29×109//L and median lactate dehydrogenase (LDH) was 374 U/L. Cytogenetic abnormalities were found in 4 cases among the 31 patients who underwent karyotype analysis or fluorescence in situ hybridization detection. There were 12 patients who had analyzable results and gene mutations were identified in 11 cases, including ASXL1, NRAS, TET2, SRSF2 and RUNX1. Among the 6 patients who were treated with HMA and could be evaluated for efficacy, 2 patients achieved complete remission, 1 patient achieved partial remission and 2 patients achieved clinical benefit. Compared with the non-HMA treatment group, overall survival (OS) time was not significantly prolonged in the HMA treatment group. Univariate analysis showed that Hb<100 g/L, ANC≥12×109/L, LDH≥250 U/L and peripheral blood (PB) blasts ≥5% were significantly associated with poor OS, while WHO classification CMML-2, Hb<100 g/L, ANC≥12×109/L, LDH≥250 U/L and PB blasts≥5% were significantly associated with poor leukemia-free survival (LFS) (P<0.05). Multivariate analysis showed that ANC≥12×109/L and PB blasts≥5% were significantly associated with poor OS and LFS (P<0.05). CONCLUSION CMML has high heterogeneity in clinical characteristics, genetic changes, prognosis and treatment response. HMA can not significantly improve the survival of CMML patients. ANC≥12×109/L and PB blasts≥5% are independent prognostic factors of OS and LFS in patients with CMML.

Abstract
OBJECTIVE To explore the clinical characteristics, treatment and prognosis of therapy-related hematological neoplasms patients secondary to malignant solid tumors. METHODS The clinical features, treatment and prognosis of 36 hematological neoplasms patients secondary to malignant solid tumors with radiotherapy and chemotherapy in the Second Hospital of Shanxi Medical University were retrospectively analyzed. RESULTS The 36 patients with therapy-related hematological neoplasms had a median age of 60 (47-81) years, 14 were male and 22 were female. Among them, 22 cases were acute myeloid leukemia, 5 cases were acute lymphoblastic leukemia, 4 cases were multiple myeloma, 3 cases were myelodysplastic syndrome, and 2 cases were non-hodgkin's lymphoma. The median latency of malignant tumor to hematological neoplasm was 42.5 (12-120) months. The median survival time of therapy-related hematological neoplasms was 10.5 (1-83) months, and the 3-year overall survival (OS) rate was 24.3%. The therapy-related acute myeloid leukemia patients had a very poor prognosis, with a median survival of 7 (1-83) months and a 3-year OS rate of 21.4%. CONCLUSION The prognosis of therapy-related hematological neoplasms secondary to malignant solid tumors with radiotherapy and chemotherapy is poor, and individualized treatment should be implemented according to the clinical situation of patients.

Abstract
BACKGROUND Hydrodissection is a widely used technique during radiofrequency ablation (RFA) for benign thyroid nodules. Although it could effectively avoid thermal injury to the surrounding critical structures and achieve complete treatment, routine operation of the remaining needle could cause perithyroidal hemorrhage. In this report, we present 2 cases of perithyroidal hemorrhage during RFA caused by a hydrodissection needle, which have not been reported before.
CASE SUMMARY A 21-year-old female and a 45-year-old male were admitted for RFA for benign thyroid nodules. Considering that their nodules were adjacent to the recurrent laryngeal nerve, the needle used for hydrodissection was placed and remained between the dorsal capsule of the lateral lobe and the recurrent laryngeal nerve. During the procedure, active bleeding near the needle appeared on ultrasonography (US). Although moderate pressure was quickly applied to the neck for several minutes, contrast-enhanced US (CEUS) still showed an active hemorrhage. A radiofrequency electrode was placed at the bleeding point under the guidance of CEUS to stop the bleeding, and the procedure was finally confirmed to be successful by CEUS, without other complications.
CONCLUSION Hydrodissection during RFA of benign thyroid nodules was associated with a risk of perithyroidal hemorrhage. The timely recognition of this acute hemorrhage could help in the timely control of the bleeding, and CEUS-guided ablation of the bleeding point could be useful.

Abstract
OBJECTIVE To investigate the prognostic value of hemopoietic scoring system composed of hemoglobin (HB), platelet count (PLT) and mean corpuscular volume (MCV) in MM patients and its correlation with curative effect. METHODS The clinical data of 172 newly diagnosed MM patients treated by bortezomib as the first-line regimen in our hospital from May 2014 to December 2019 were collected, three variables (HB≤100 g/L, PLT≤150×109/L, MCV≥96 fl) were introduced, each variable was distributed 1 score, the patients were divided into four groups (0, 1, 2 and 3 points in group 1, 2, 3 and 4, respectively), and the clinical characteristics and prognosis of the patients in the four groups were analyzed. The initial efficacy evaluation after 3-4 courses of treatment was carried out, and the curative effect of the patients in the different hematopoiesis score groups were compared. RESULTS The median OS time of the patients in group 1, 2, 3 and 4 was 27.0, 22.5, 20.7 and 18.1 months, while the median PFS time were 23.0, 19.0, 18.0 and 14.0 months, respectively. The OS and PFS of the patients in low score group were significantly better than those in high score group (P=0.045, P=0.048). There was no significant difference in the curative effect of the patients treated by bortezomib after 3-4 courses (P>0.05). CONCLUSION Hematopoiesis score can preliminarily predict the overall survival of newly diagnosed MM patients, but there is no significant difference between different scoring groups in the initial curative effect.

Abstract
OBJECTIVE To investigate the clinical characteristics and prognosis of multiple myeloma patients with myelofibrosis. METHODS The clinical data of 263 patients with multiple myeloma (including 92 patients with myelofibrosis) treated in the department of hematology of our hospital from January 1, 2016 to June 31, 2020 were collected and retrospectively analyzed, the patients were divided into combined group and uncombined group. The MM stage, MM type, genetic characteristics and therapeutic effect of the patients in combined group and uncombined group were observed, and the relationship between the curative effect and the degree of myelofibrosis change of the patients in combined group was analyzed. RESULTS There was no statistically difference in the MM staging and classification between multiple myeloma patients with or without myelofibrosis (P>0.05). The positive rate of FISH results of the patients in combined group was significantly higher than those in uncombined group, and was significantly correlated to 1q21 amplification, D13S319 deletion, and IgH breakage (P<0.05). After treatment, the effective rate of the patients in uncombined group was significantly higher than those in combined group, and the degree of fibrosis in the effective patients in combined group was significantly reduced. CONCLUSION The survival rate of the patients with multiple myeloma complicated with myelofibrosis is shorter than that of the patients without myelofibrosis, and the overall prognosis is poor.

Abstract
OBJECTIVE To compare the efficacy and safety of different chemotherapy regimens in elderly multiple myeloma (MM) patients with different Frailty scores. METHODS The clinical data of elderly patients with MM were retrospectively analyzed, including age, treatment regimen, efficacy, adverse reactions, and the Frailty score included in the activity of daily living score, the instrumental activity of daily living scale and the Charlson comorbidity index. The patients were divided into fit group, mediate fit group and frail group according to the scoring standard. The treatment efficiency and adverse reaction rates of elderly MM with different physical conditions treated by different chemotherapy regimens were analyzed. RESULTS Among the 70 patients, the effective rates of the patients in fit group, the mediate fit group, and the frail group were 79.5%, 81%, and 40%, and the effective rates of the fit patients in double and triple groups were 54.5% and 89.3%, 70% and 90.9% for mediate fit patients, 42.9% and 33.3% for frail patients, the triple regimen in fit patients showed obvious advantages, and the difference showed statistically significant (P<0.05), while the efficacy for mediate patients and frail patients showed no significant difference. During the induction of bortezomib, the incidence of adverse reactions for the patients in the triple group (78.6%) was higher than 67.9% in the double group, and the difference showed no statistically significant (P>0.05).There was no significant difference in the 1-year overall survival rate of the patients and with molecular genetic abnormalities among each groups. CONCLUSION The therapeutic effect is related to the patient's physical condition. For patients with healthy physique, the triple regimen should be used first. For patients with weak physical constitution, the chemotherapy regimen with low drug toxicity should be selected for safety.

Abstract
Objective: To investigate the pathogen distribution and antimicrobial resistance among lower respiratory tract infections in patients with hematological malignancies. Methods: Sputum samples were collected from 967 patients with hematological malignancies and lower respiratory tract infections in Department of Hematology,the Second Hospital of Shanxi Medical University from January 2017 to July 2020. The pathogens and drug sensitivity reports were carried out by automatic bacterial identification instruments. WHONET 5.6 and SPSS 20.0 softwares were used for statistical analysis. Results: A total of 961 strains of pathogens were isolated, 516 (53.7%) pathogens were Gram-negative bacteria, mainly 118 strains of Klebsiella pneumonia (12.3%), 68 strains of Pseudomonas aeruginosa (7.1%), 67 strains of Acinetobacter baumannii (7.0%),52 strains of Stenotrophomonas maltophilia (5.4%), 43 strains of Escherichia coli (4.5%), and 42 strains of Enterbacter cloacae (4.4%). There were 171 (17.8%) strains of Gram-positive bacteria and 274 (28.5%) fungi. The drug resistance rates of Pseudomonas aeruginosa and Acinetobacter baumannii to carbapenem were 22.1%-31.3%. Stenotrophomonas maltophilia was sensitive to levofloxacin, compound sulfamethoxazole and minocycline. The antimicrobial resistance rates of these three enterobacteria to carbapenems, cefoperazone/sulbactam, piperacillin/tazobactam were low (<10%). The resistant Gram-positive bacteria to ticoplanin, vancomycin and linazolamide were not detected. Conclusion: The major pathogens related to lower respiratory tract infections in patients with hematological malignancies are gram-negative bacteria in our centre. Different pathogens appear different characteristics of antimicrobial resistance.

Abstract
Leonurine, an active natural alkaloid compound isolated from Herba leonuri, has been reported to exhibit promising anticancer activity in solid tumors. The aim of this study was to explore whether leonurine is able to inhibit chronic myeloid leukemia (CML) malignancy. Here, we found that leonurine dose dependently inhibited the proliferation, migration, colony formation and promoted apoptosis of CML cells. Furthermore, leonurine markedly reduced CML xenograft growth in vivo. Mechanically, leonurine upregulated SOCS5 expression, thus leading JAK2/STAT3 signaling suppression. Silencing of SOCS5 by its siRNA abrogated the effect of leonurine on CML cells, demonstrating that SOCS5 mediates the anti-leukemia effect of leonurine. Notably, we observed that miR-18a-5p was remarkably increased in CML cells. Treating CML cells with leonurine significantly decreased miR-18a-5p expression. Moreover, we found miR-18a-5p repressed SOCS5 by directly targeting its 3′-UTR. miR-18a-5p downregulation induced by leonurine reduced the biological activity of CML cells by relieving miR-18a-5p repression of SOCS5 expression. Taken together, leonurine exerts significant anti-leukemia efficacy in CML by regulating miR-18a-5p/SOCS5/JAK2/STAT3 axis.

Abstract
In this study, desert grassland, grassland edge, shrubland edge, shrubland were selec-ted as four transition sites in a nearly 30 years typical desert grassland-shrubland mosaic formed by anthropogenic shrub introduction. Soil properties and soil microbial characteristics under vegetation patches and bare interspace in each site were investigated to examine the responses of soil nitrogen to the desert grassland-shrubland state transition. It was shown that the aboveground biomass increased with transition from desert grassland to shrubland. Annual herbs increased largely with the introduction of shrubs. Soil moisture, microbial biomass and total nitrogen and carbon decreased with the transition. The abundance of microogranisms was lower in grassland edge and shrubland edge, and then increased in shrubland, which was slightly higher than that of desert grassland. With respect to nitrogen, nitrate content reached the highest level of 28.45 mg N·kg-1 and ammonium reached the lowest level of 4.81 mg N·kg-1 in shrubland, which were significantly increased by 52.3% and decreased by 10.4% compared with desert grassland. In addition, soil moisture and microbial biomass nitrogen was positively correlated across all sites. The relationship between mine-ralized nitrogen and soil moisture was non-linear, as they were positively correlated in desert grassland and grassland edge, but negatively correlated in shrubland edge and shrubland. During the 30-year transition from desert grassland to shrubland, our results showed that soil total nitrogen and microbial biomass nitrogen were significantly decreased, but mineralized nitrogen, especially for nitrate, significantly increased over time, indicating that soil nitrification was inhibited in desert grassland but accelerated in shrubland.

Abstract
To understand the responses of soil extracellular enzyme activities to the desert grassland-shrubland anthropogenic transition, we examined soil properties and six extracellular enzyme activities, in soil under vegetation patches and bare interspaces in desert grassland, grassland edge, shrubland edge, shrubland in a typical anthropogenic desert grassland-shrubland mosaic in desert steppe of eastern Ningxia, China. The six measured enzymes included cellobiohydrolase, β-1,4-xylosidase, β-1,4-glucosidase, β-1,4-N-acetylglucosaminidase, leucine aminopeptidase and alkaline phosphatase. We found that soil moisture, soil organic carbon, total nitrogen, total phosphorus, microbial biomass carbon and microbial biomass nitrogen decreased significantly by 26.0%-88.5% with the process of the desert grassland-shrubland anthropogenic transition. All soil properties, except soil organic carbon and soil moisture in grassland edge site, were 3.9%-82.3% higher under vegetation patches than those in bare interspaces in each site. The six extracellular enzyme activities also decreased by 22.1%-82.4% in the transition process, especially for leucine aminopeptidase and alkaline phosphatase, showing significant decrease by 82.4% and 75.5%, respectively. All extracellular enzyme activities but β-1,4-N-acetylglucosaminidase in shrubland were significantly higher by 10.7%-42.7% under vegetation patches than those in bare interspaces in each site. The activities of six extracellular enzymes were all positively correlated with each other. All of them were positively correlated with soil properties. Moreover, activities of these soil extracellular enzymes responded more positively to the changes of microbial biomass carbon, microbial biomass nitrogen, and total nitrogen in the process of anthropogenic transition.

Abstract
Objective: To analyze the clinical characteristics of patients with ankylosing spondylitis (AS) with inflammation bowel disease (IBD). Methods: AS patients fulfilling the 1984 modified New York diagnostic criteria were recruited in Chinese AS Prospective Imaging Cohort (CASPIC) consecutively from April 2016 to June 2017 in Chinese People's Liberation Army General Hospital by using smart management system for spondyloarthritis (SpAMS). The diagnosis of IBD was confirmed by tissue pathology via ileocolonoscopy. Demographic, clinical and biochemical data were collected. Results: In total, 893 patients with AS were recruited with the mean age 30.8 years. The majority were men (739, 82.8%). There were 64 (7.2%) patients concomitant with IBD. The mean age [(34.5±7.5) years vs. (30.5±8.8) years, P<0.001] was older and the disease duration [(10.8±6.9) years vs. (8.1±5.9) years, P=0.001] was longer in patients with IBD than patients without. Compared with patients without IBD, patients with IBD had more frequent involvement of the cervical spine [(21.9% (14/64) vs. 10.5% (87/829), P=0.006) and thoracic spine [29.7% (19/64) vs. 12.3% (102/829), P<0.001]. Uveitis [28.1% (18/64) vs. 16.4% (136/829), P=0.017] and psoriasis [7.8% (5/64) vs. 2.3% (19/829), P=0.009] were also more common in patients concomitant with IBD. In addition, patients with IBD had significantly higher scores in BASDAI (3.3±2.1 vs. 2.4±1.8, P<0.001), BASFI [2.2 (1.0,3.3) vs. 1.1(0.2,2.4), P<0.001)] and ASAS HI (7.1±4.3 vs. 5.3±3.7, P= 0.001) than patients without IBD. Conclusions: Compared with patients without IBD, AS patients concomitant with IBD have more severe disease activity and organ dysfunction. Furthermore, the uveitis and psoriasis are more frequently accompanied in AS patients with IBD.

Abstract
BACKGROUND The aim of this study was to detect the expression of long noncoding RNA small nucleolar RNA host gene 18 (SNHG18) andsemaphorin 5A (SEMA5A) genes in multiple myeloma (MM) patients and to explore the correlation of the expression of these genes with the clinical characteristics and prognosis of MM patients. METHODS Forty-seven newly diagnosed MM, 18 complete remission MM, 13 refractory/relapse MM, and 22 iron deficiency anemia (serving as control) samples were extracted at the Department of Hematology, Second Affiliated Hospital of Xian Jiaotong University between January 2015 and December 2016. The clinical features of the MM patients are summarized. Real-time quantitative PCR was performed to analyze the relative expression levels of the SNHG18 and SEMA5Agenes. The clinical characteristics and overall survival (OS) of the MM patients were statistically analyzed while measuring different levels of SNHG18 and SEMA5Agene expression. At the same time, the correlation between the expression of SNHG18 and SEMA5A was also analyzed. RESULTS The analysis confirmed that SNHG18 and its possible target gene SEMA5A were both highly expressed in newly diagnosed MM patients. After analyzing the clinical significance of SNHG18 and SEMA5A in MM patients, we found that the expression of SNHG18 and SEMA5A was related to the Durie-Salmon (DS), International Staging System (ISS), and Revised International Staging System (R-ISS) classification systems, and the Mayo Clinic Risk Stratification for Multiple Myeloma (mSMART; p < 0.05). Moreover, we observed a significant difference in OS between the SNHG18/SEMA5A high expression group and the low expression group. We found a positive correlation between SNHG18 and SEMA5A expression (r = 0.709, p < 0.01). Surprisingly, the expected median OS times of both the SNHG18 and SEMA5Ahigh expression groups were significantly decreased, which was in contrast to those of both the SNHG18 and SEMA5Alow expression groups and the single-gene high expression group (p < 0.05). CONCLUSION High expression of both SNHG18 and SEMA5A is associated with poor prognosis in patients with MM.

Abstract
BACKGROUND Pioneering effort has been made to facilitate the recognition of pathology in malignancies based on whole-slide images (WSIs) through deep learning approaches. It remains unclear whether we can accurately detect and locate basal cell carcinoma (BCC) using smartphone-captured images. OBJECTIVES To develop deep neural network frameworks for accurate BCC recognition and segmentation based on smartphone-captured microscopic ocular images (MOIs). METHODS We collected a total of 8046 MOIs, 6610 of which had binary classification labels and the other 1436 had pixelwise annotations. Meanwhile, 128 WSIs were collected for comparison. Two deep learning frameworks were created. The 'cascade' framework had a classification model for identifying hard cases (images with low prediction confidence) and a segmentation model for further in-depth analysis of the hard cases. The 'segmentation' framework directly segmented and classified all images. Sensitivity, specificity and area under the curve (AUC) were used to evaluate the overall performance of BCC recognition. RESULTS The MOI- and WSI-based models achieved comparable AUCs around 0·95. The 'cascade' framework achieved 0·93 sensitivity and 0·91 specificity. The 'segmentation' framework was more accurate but required more computational resources, achieving 0·97 sensitivity, 0·94 specificity and 0·987 AUC. The runtime of the 'segmentation' framework was 15·3 ± 3·9 s per image, whereas the 'cascade' framework took 4·1 ± 1·4 s. Additionally, the 'segmentation' framework achieved 0·863 mean intersection over union. CONCLUSIONS Based on the accessible MOIs via smartphone photography, we developed two deep learning frameworks for recognizing BCC pathology with high sensitivity and specificity. This work opens a new avenue for automatic BCC diagnosis in different clinical scenarios. What's already known about this topic? The diagnosis of basal cell carcinoma (BCC) is labour intensive due to the large number of images to be examined, especially when consecutive slide reading is needed in Mohs surgery. Deep learning approaches have demonstrated promising results on pathological image-related diagnostic tasks. Previous studies have focused on whole-slide images (WSIs) and leveraged classification on image patches for detecting and localizing breast cancer metastases. What does this study add? Instead of WSIs, microscopic ocular images (MOIs) photographed from microscope eyepieces using smartphone cameras were used to develop neural network models for recognizing BCC automatically. The MOI- and WSI-based models achieved comparable areas under the curve around 0·95. Two deep learning frameworks for recognizing BCC pathology were developed with high sensitivity and specificity. Recognizing BCC through a smartphone could be considered a future clinical choice.

Abstract
OBJECTIVE To investigate the proliferation- inhibitory and apoptosis inducing effect of ganglioside GM3 on human multiple myeloma cell line U266 cells and its possible mechanisms. METHODS MTT assay and flow cytometry were used to observe the effects of GM3 ganglioside on proliferation and apoptosis of human myeloma cell line U266. Effects of different concentration of ganglioside GM3 on the mRNA expression level of BCL-2 and BAX were detected by Real-time PCR. RESULTS MTT assay and Flow Cytometry showed that ganglioside GM3 could induce the apoptosis and inhibit the proliferation of multiple myeloma U266 cell line, and both the effects were enhanced with the increase of GM3 ganglioside concentration. Compared with the control group, the relative expression of BAX mRNA with the increase of GM3 concentration in experimental group was enhanced gradually(r=0.968), while the relative mRNA expression of anti-apoptotic gene BCL-2 was decreased gradually(r=-0.727). CONCLUSION GM3 ganglioside can induce apoptosis and inhibit the proliferation of U266 cell line in a concentration dependent manner. The mechanism may be related with up- regulation of BAX expression and down-regulation of BCL-2.

Abstract
OBJECTIVE To investigate the expression of insulin-like growth factor binding protein 7 (IGFBP7 ) gene in multiple myeloma cell line U266, and study the effect of 5-aza-2'-deoxycytidine (5-aza-dc) on proliferation of U266 cells. METHODS multiple myeloma cell line U266 was cultured in vitro. The bone marrow mononuclear cells from healthy persons(N-BMMNC) were collected and used as normal controls. The IGFBP7 mRNA expression of U266 cells and N-BMMNC were detected by real-time fluorescence quantitative PCR, the DNA methylation status of the IGFBP7 CpG island was measured by using methylation-specific PCR(MSP). The different concentrations of 5-aza-dc (5 µmol/L, 10 µmol/L, 20 µmol/L) were used to treat U266 cells for 48 hours, the RT-PCR and Western blot were used to detect the effect of IGFBP7 mRNA and protein expressions, the cell growth curve and Annexin V/PI were analyzed by flow cytometry. RESULTS As compared with normal BMMNC, the lower expression of IGFBP7 gene was found in U266 cells, the obvious hypermethylation of the CpG island in the IGFBP7 promoter was observed. After treatment of U266 treating with different concentrations of 5-aza-dc, the IGFBP7 mRNA expression was up-regulated dose-dependently(P<0.05), the U266 cells grew slowly and apoptosis rates were enhanced dose-dependently. CONCLUSION As the hypermethylalion of CpG island in IGFBP7 promoter is a frequent event in lower expression of IGFBP7 gene in U226 cells, the 5-aza-dc can up-regulate the expression of IGFBP7 , and can inhibit cell proliferation through induction of cell apoptosis and arrest of cell cycle.

Abstract
Objective: The aim of this study was to set up a large, longitudinal and prospective database to compare the clinical manifestations in human leucocyte antigen (HLA)-B(27) positive and negative patients with ankylosing spondylitis(AS) based on real-world evidence in Chinese population. Methods: A total of 897 outpatients with confirmed AS were recruited consecutively by smart management system for spondyloarthritis (SMSP) from April 13, 2016 to June 6, 2017 in Chinese PLA General Hospital from 30 provinces and autonomous regions. 801 patients with HLA-B(27) data were included in the analysis. Demographic and clinical parameters including Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), ankylosing spondylitis disease activity score (ASDAS), arthritis, enthesitis, Bath ankylosing spondylitis metrology index (BASMI), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were compared between HLA-B(27) positive and negative groups. Results: A total of 801 patients were included in the analysis with an average age of (30.7±8.8) years. There were 659 males and 142 females and HLA-B(27) was present in 88.0%(705/801). Males were significantly more in HLA-B(27) positive patients [83.3%(587/705) vs. 75.0%(72/96); P=0.047].The average age at disease onset was (22.3±7.6)years in HLA-B(27) positive patients and (24.4±8.7) years in HLA-B(2)7 negative ones (P=0.028).There was significant difference in diagnose delay between two groups [14.3(2.5,43.6)months in HLA-B(27) positive patients vs. 20.3(5.0,67.4) months in HLA-B(27) negative ones, P=0.041]. Anterior uveitis was found to be significantly more common in HLA-B(27) positive patients [18.9% (133/705)vs.7.3%(7/96),P=0.005], and knee involvement less common in HLA-B(27) positive patients [4.0%(27/682) vs.10.0%(9/90), P=0.010], conversely. CRP[6.5(3.0, 16.4)mg/L vs. 3.5(1.6, 12.3)mg/L] and ESR[11.0(4.0, 24.0)mm/1h vs. 7.0(3.0, 16.0)mm/1h] were significantly higher in HLA-B(27) positive patients(P=0.005,0.013, respectively).But no differences in BASDAI,ASDAS,BASFI and BASMI were obtained between two groups. Conclusions: HLA-B(27) positive patients had a higher proportion of males, a younger age of onset and a greater risk for occurrence of anterior uveitis, suggesting a poorer prognosis.

Abstract
The worldwide infection rate of herpesvirus is high, but the detailed prevalence in China, especially the central area, remains unclear. In the present study, the prevalence of herpes simplex virus (HSV), Epstein-Barr virus (EBV), and human cytomegalovirus (HCMV) was investigated in 303 healthy adults in Wuhan, a representative city in Central China. Viral-specific IgG and IgM titers were examined in the serum by chemiluminescent immunoassay, and the existence of viral genomic DNA in blood cells was determined by nested PCR. The overall IgG seroprevalences were 81.5%, 95.4%, and 93.7% for HSV, EBV, and HCMV, while the corresponding IgM seroprevalences were only 6.3%, 2.3%, and 0. The viral genomic DNA of HSV, EBV, and HCMV was identified in the blood samples of 5.9%, 14.2%, and 22.8% of the tested donors, respectively. Significantly, less HSV IgM-positive samples were found in the population over 20 years old than below 20 group; female displayed higher chances for HSV IgG and genome positivity; and occupations such as waiters and medical staffs were shown to be with higher risk for HCMV genome positivity. This study provided useful reference data for the HSV, EBV, and HCMV prevalence in central China, and suggested the potential importance of detecting viral genome to complement serum test data.

Abstract
Streptococcus agalactiae (S. agalactiae) is an important fish pathogen, which has received more attention in the past decade due to the increasing economic losses in the tilapia industry worldwide. As existing effective vaccines of S. agalactiae in fish have obvious disadvantage, to select immunoprotective antigens and package materials would undoubtedly contribute to the development of novel oral vaccines. In the present study, surface immunogenic protein (sip) was selected from the S. agalactiae serovar I a genomes as immunogenic protein in DNA vaccine form with cationic chitosan and biodegradable and biocompatible PLGA. The pcSip plasmid in cationic-PLGA was successfully expressed in tissues of immunized tilapia and the immunogenicity was assessed in tilapia challenge model. A significant increase was observed in the cytokine levels of IL-1β, TNF-α, CC1, CC2 in spleen and kidney tissues. Furthermore, immunized tilapia conferred different levels of protection against challenge with a lethal dose of highly virulent serovar I a S. agalactiae. Our results indicated that the pcSip plasmid in cationic-PLGA induced high level of antibodies and protection against S. agalactiae infection, could be effective oral DNA vaccine candidates.

Abstract
BACKGROUND Previous studies examining associations between subclinical hypothyroidism (SCH) with in vitro fertilization (IVF) outcome indicate some benefits of levothyroxine (LT4) treatment. But IVF outcomes in treated SCH women whose serum Thyroid Stimulating Hormone (TSH) concentration did and did not exceed 2.5 mIU/L before the IVF cycle has not been studied thoroughly. METHODS In this study, we performed a prospective cohort study with 270 treated subclinical hypothyroidism patients undergoing their first IVF retrieval cycle at a single cite. RESULTS SCH in women receiving LT4 replacement with a basal TSH level between 0.2-2.5mIU/L displayed a similar rate of clinical pregnancy (47.4% vs 38.7%, P = .436), miscarriage (7.4% vs 16.7%, P = .379) and live birth (43.9% vs 32.3%, P = .288) compared to women with a basal TSH level between 2.5-4.2 mIU/L. CONCLUSION Strictly controlled TSH (less than 2.5 mIU/L) before IVF may have no effect on the pregnancy rate in LT4 treated SCH women.

Abstract
Objective: To analyze the clinical and gene mutation characteristics of dynamin-1 (DNM1)-related infantile spasms. Method: Clinical, laboratory and genetic data of one case of DNM1-related infantile spasms diagnosed by Xiangya Hospital in September 2015 were analyzed.Through taking "Dynamin-1" "DNM1" as key words to search at CNKI, Wanfang, PubMed and OMIM to date (April 2016), the clinical characteristics of 9 reported cases of DNM1-related epileptic encephalopathy in international literature with our case were reviewed. Result: The boy is the second child of healthy and nonconsanguineous parents.At 7 months, he started to have seizures with head dropping, and he was brought for the first time to our hospital at the age of 17 months.The patient presented with severe psychomotor retardation, epilepsy, muscular hypotonia, and electroencephalography showed hypsarhythmia.He received 28 days of adrenocorticotropic hormone (ACTH) therapy.After that, his seizures were improved with valproic acid and levetiracetam, and disappeared between 3 years and 5 months to 5 years and 5 months of age on treatment with valproic acid only.Exome-sequencing study (trios) identified novel heterozygous mutation c. 443A>G (p.Glu148Arg) in DNM1. Up to now, 9 cases of epileptic encephalopathy (infantile spasms or Lennox-Gastaut syndrome) associated with de novo DNM1 gene mutations have been reported. Conclusion: The main clinical features of DNM1 mutations include intractable seizures, intellectual disability, developmental delay, hypotonia, and developmental delay before the onset of seizures.

Abstract
Human cytomegalovirus (HCMV) is the leading infectious cause of birth defects, and may lead to severe or lethal diseases in immunocompromised individuals. Several HCMV strains have been identified and widely applied in research, but no isolate from China has been characterized. In the present study, we isolated, characterized and sequenced the first Chinese HCMV clinical strain Han, and constructed the novel and functional HCMV infectious clone Han-BAC-2311. HCMV Han was isolated from the urine sample of a Chinese infant with multiple developmental disorders. It expresses HCMV specific proteins and contains a representative HCMV genome with minor differences compared to other strains. By homologous recombination using mini-F derived BAC vector pUS-F6, the infectious clone Han-BAC-2311 was constructed containing representative viral genes across the HCMV genome. The insertion site and orientation of BAC sequence were confirmed by restriction enzyme digestion and Southern blotting. The reconstituted recombinant virus HanBAC-2311 expresses typical viral proteins with the same pattern as that of wild-type Han, and also displayed a similar growth kinetics to wild-type Han. The identification of the first clinical HCMV strain in China and the construction of its infectious clone will greatly facilitate the pathogenesis studies and vaccine development in China.

Abstract
The codon usage patterns of open reading frames (ORFs) in cyprinid herpesvirus 3 (CyHV-3) have been investigated in this study. The high correlation between GC12 % and GC3 % suggests that mutational pressure rather than natural selection is the main factor that determines the codon usage and base component in the CyHV-3, while mutational pressure effect results from the high correlation between GC3 % and the first principal axis of principle component analysis (Axis 1) on the relative synonymous codon usage (RSCU) value of the viral functional genes. However, the interaction between the absolute codon usage bias and GC3 % suggests that other selections take part in the formation of codon usage, except for the mutational pressure. It is noted that the similarity degree of codon usage between the CyHV-3 and goldfish, Carassius auratus (L.), is higher than that between the virus and common carp, Cyprinus carpio L., suggesting that the goldfish plays a more important role than the common carp in codon usage pattern of the CyHV-3. The study of codon usage in CyHV-3 can provide some evidence about the molecular evolution of the virus. It can also enrich our understanding about the relationship between the CyHV-3 and its hosts by analysing their codon usage patterns.

Abstract
It is well known that exercise training exhibits renal protective effects in animal models of hypertension and chronic renal failure. However, the mechanisms regulating these effects of exercise training remain unclear. This study aimed to investigate the role of mitochondrial function in exercise-induced attenuation of renal injury in spontaneously hypertensive rats (SHR). The adult male SHR and age-matched normotensive Wistar-Kyoto rats (WKY) were given moderate-intensity exercise for 12 weeks or treated with MitoQ10 for 8 weeks. In this work, exercise training in SHR reduced blood pressure, and effectively attenuated renal dysfunction, marked by reduced creatinine excretion, albuminuria, blood urea nitrogen, and glomerular sclerosis. Exercise training in SHR reduced MDA levels in plasma and kidneys and suppressed formation of 3-nitrotyrosine in kidneys. Exercise training suppressed mitochondrial ROS and [Formula: see text] formation, enhanced ATP formation, reduced mitochondrial swelling, and restored electron transport chain enzyme activity in kidneys of SHR. Furthermore, exercise training upregulated protein expression of uncoupling protein 2 and manganese superoxide dismutase in kidneys of SHR. In addition, treatment with mitochondria-targeted antioxidant MitoQ10 exhibited similar renal protective effects in SHR. In conclusion, chronic aerobic exercise training preserved mitochondrial function and abated oxidative stress in the kidneys of SHR, which may in part explain the protective effect of exercise on renal function and structure in hypertensive individuals.

Abstract
The objective of this study was to investigate the effect of the new generation of tyrosine kinase inhibitor flumatinib mesylate on C-MYC, HIF-1α and VEGF in multiple myeloma (MM) cell line U266. Different concentrations (1, 5, 10 µmol/L) of flumatinib mesylate were used to act on U266 cell line for 8, 16 and 24 h, and the expression of C-MYC, and HIF-1α genes was detected by real-time fluorescence-quantitative PCR, the expression of C-MYC, HIF-1α and VEGF was measured by Western blot. The results showed that the gene expression of C-MYC and HIF-1 genes decreased gradually with the increasing of flumatinib mesylate concentration (P < 0.05). At the same concentration of flumatinib mesylate, the expression of C-MYC and HIF-1α gene decreased gradually with prolonging of treatment time with the flumatinib mesylate (P < 0.05). When the flumatinib mesylate acted the U266 cell line for 16 h, the expression of C-MYC, HIF-1α and VEGF decreased gradually with the increasing of flumatinib mesylate concentration (P < 0.05). It is concluded that the flumatinib mesylate can reduce the expression of C-MYC, HIF-1 α and VEGF in U266 cell line in a time- and dose-dependent manners, so flumatinib mesylate may become a new drug for MM therapy.

Abstract
This study was purposed to explore the relationship between the mRNA expression of telomere protection protein TIN2 and POT1 and the pathogenesis of myelodysplastic syndrome (MDS). The expression of TIN2 and POT1 genes at the mRNA levels were detected by real-time fluorescence quantitative PCR in 51 patients with MDS and 10 normal controls. The results showed that the mRNA expressions of TIN2 in RA/RARS/RCMD/MDS-U, RAEB-1 and RAEB-2 groups according to the World Health Organization criteria were significantly higher than that in the controls (P < 0.05); the mRNA expressions of POT1 in RA/RARS/RCMD/MDS-U, RAEB-1 and RAEB-2 groups were significantly lower than that in the controls (P < 0.05). The mRNA expressions of TIN2 in high-risk group, inter risk-2 group and inter risk-1 group according to the international prognostic scoring system criteria were significantly higher than that in controls (P < 0.05). There was no significant difference between low risk group and the control group. The mRNA expressions of POT1 in high risk group, inter-risk-2 group and inter-risk-1 group were significantly lower than the controls (P < 0.05). There was no significant difference between low risk group and the control group. The mRNA expression of TIN2 in normal chromosome group was significantly lower than that in abnormal chromosome group (P < 0.05). There was no significant difference between normal chromosome group and the control group. The mRNA expression of POT1 in normal chromosome group was significantly higher than that in abnormal chromosome group (P < 0.05). There was no significant difference between normal chromosome group and the control group. It is concluded that the abnormal mRNA expression of TIN2 and POT1 may be involved in the regulation of telomere dynamics of MDS patients, the regulatory mechanism may be related to the telomere length and the pathogenesis of MDS.

Abstract
Human cytomegalovirus (HCMV) is a herpesvirus that causes congenital diseases and opportunistic infections in immunocompromised individuals. Its functional proteins and microRNAs (miRNAs) facilitate efficient viral propagation by altering host cell behavior. The identification of functional target genes of miRNAs is an important step in the study of HCMV pathogenesis. HCMV encodes at least 14 miRNAs, including hcmv-mir-UL148D, which resides in the HCMV UL/b' region. hcmv-mir-UL148D is the only miRNA encoded by the HCMV UL/b' region; however, its targets and functional effects have not yet been eludidated. In this study, hybrid-PCR screening was used to identify target genes and dual luciferase reporter assay was used to evaluate the binding effect of hcmv-miR-UL148D to the 3' untranslated region (3'UTR) of IEX-1. In addition, western blot analysis was used to detect the expression kinetics of IEX-1 protein and apoptosis assay was used to identify the effects of hcmv-miR-UL148D on cell apoptosis. The hybrid-PCR results showed that only one binding site in the 3'UTR of the cellular gene, human immediate early gene X-1 (IEX-1), was completely complementary to an 11 nucleotide (nt) sequence in the 5' terminus of hcmv-mir-UL148D, including the entire seed region. The binding site was demonstrated to be functional by dual luciferase reporter assay with a 47% repression of the relative luciferase activity. In an in vitro system of human embryonic kidney 293 (HEK293) cells, the ectopically expressed hcmv-mir-UL148D exhibited a downregulatory effect on IEX-1 expression, and decreased the cell apoptosis induced by transfected IEX-1. Our data demonstrate that hcmv-mir-UL148D targets the cellular gene, IEX-1, downregulating its expression and thus results in anti-apoptotic effects.

Abstract
It is well known that exercise training attenuates aortic remodeling and improves endothelial function in spontaneously hypertensive rats (SHR). However, the underlying molecular mechanism remains unclear. Hydrogen sulfide (H(2)S) and nitric oxide (NO), as two established physiologic messenger molecules, have important roles in the development of aortic remodeling and endothelial dysfunction in hypertensive animals and patients. In this work, it was found that exercise training had no significant effect on blood pressure, but effectively attenuated baroreflex dysfunction in SHR. Exercise training in SHR attenuated aortic remodeling and improved endothelium-mediated vascular relaxations of aortas in response to acetylcholine. Interestingly, exercise training in SHR restored plasma H(2)S levels and aortic H(2)S formation and enhanced levels of mRNA for cystathionine γ-lyase in aortas. Furthermore, exercise training in SHR resulted in augmentation of nitrite and nitrate (NOx) contents and reduction of asymmetric dimethylarginine contents of aortas, upregulation of dimethylarginine dimethylaminohydrolase 2, and phosphorylation of nitric oxide synthase 3, but had no significant effect on protein levels of NOS3. In addition, exercise training could effectively reduce malondialdehyde production and suppressed formation of O(2) (-), and OONO(-) in aortas of SHR through enhancing activities of superoxide dismutase and catalase, and suppressing NADPH oxidase activity. In conclusion, exercise training ameliorates aortic hypertrophy and endothelial dysfunction, possibly via restoring bioavailabilities of hydrogen sulfide and nitric oxide in SHR.

Abstract
This study was purposed to explore the effect of a new generation of histone deacetylase inhibitor LBH589 alone or combined with bortezomib (Bor) on multiple myeloma cells (MM1R) in vitro. The effect of LBH589 (10, 20, 50 nmol/L) alone or combined with Bor (10, 20 nmol/L) on MM1R proliferation was detected by MTT method; the effect of LBH589 on cell cycle and apoptosis of MM1R cells were determined by flow cytometry; the histone H4 acetylation level of MM1R cells treated with LBH589 (10, 20, 50 nmol/L) for 24 h was analyzed by Western blot. The results showed that the LBH589 alone or combined with Bor all could inhibit the proliferation of MM1R cells in a concentration- and time-dependent manner. After MM1R cells were treated with drugs for 48 h, the cells in G(0)/G(1) phase increased, the cells in G(2)/M and S phase decreased, suggesting the arrest of cells in G(0)/G(1) phase, at the same time, the apoptosis rate of MM1R cells treated with drugs increased in a concentration-dependent manner, while the effect of LBH589 combined with Bor was more obvious than that of LBH589 alone (P < 0.001). Western blot analysis showed that the histone H4 acetylation level was enhanced in concentration-dependent manner after MM1R cells were treated with different concentrations of LBH589 for 24 h. It is concluded that the LBH589 can inhibit the proliferation of MM1R cells, block the cell cycle, induce cell apoptosis, moreover LBH589 combined with Bor has synergistic effect on MM1R cells.

Abstract
The objective of this study was to investigate expression of interferon regulatory factors (ICSBP/IRF8) and the potential role of DNA methylation in silencing ICSBP/IRF8 gene in multiple myeloma (MM) cell line U266 and bone marrow mononuclear cells from 10 MM patients (MM-BMMNC). The bone marrow mononuclear cells from 10 healthy persons (N-BMMNC) were collected and used as normal controls. Expression of ICSBP/IRF8 gene was detected by real-time fluorescence quantitative PCR (using 2(-ΔΔCT) to calculate); DNA methylation level of the ICSBP/IRF8 gene was measured using methylation-specific PCR (using the ratio of interest gene ICSBP/IRF8 and internal reference β-actin expression as results). The results showed that as compared with N-BMMNC the lower expression of ICSBP/IRF8 gene was found in U266 cells and MM-BMMNC, the hypermethylation of the CpG island in the ICSBP/IRF8 promoter was observed, there were significant differences between N-BMMNC and MM-BMMNC or U266 cells (P < 0.05). It is concluded that the expression of ICSBP/IRF8 gene can be silenced in the MM-BMMNC and U226 cells. As the hypermethylation of CpG island in ICSBP/IRF8 promoter is a frequent event in MM cells, the ICSBP/IRF8 gene silencing caused by DNA methylation may take part in the pathogenesis and development of MM.

Abstract
AIM: To investigate the sequence polymorphisms in the open reading frame (ORF) of the UL147 gene in clinical strains of cytomegalovirus and to identify the relationship between UL147 sequence polymorphism and cytomegalovirus hepatitis.
METHODS: The ORF of the UL147 gene in 19 cytomegalovirus strains isolated from infants with cytomegalovirus hepatitis was amplified by PCR and sequenced.
RESULTS: In comparison with the sequence of the Toledo strain, strain-specific polymorphisms were present in the 5' end of the UL147 ORF, and the polymorphisms were located in the 5' end of sequence. The UL147 ORF varied from 477-480 kb. No sequence differences were found between strains isolated from infants with cytomegalovirus hepatitis and asymptomatic patients.
CONCLUSION: The ORF of the UL147 gene is hypervariable in different cytomegalovirus strains. The conservation of predicted UL147 product in clinical strains suggests that UL147 gene polymorphisms have no relationship with the severity of cytomegalovirus hepatitis.

Abstract
Here we describe a simple physical vapor deposition (PVD) method to prepare large quantity of highly monodispersed perylene nanotablets with a deposition-temperature controlled approach. The nanotablets produced are 1 microm octagon with 100-200 nm thickness. Confocal microscopic images of the nanotablets excited with a UV light show not only yellow color emission which is quite different from perylene monomers but also the obvious light-wave guiding properties. The formation of beta form nanocrystals shows that our method is highly selective for only one kind of perylene nanocrystals, which makes sure the uniform optical and electronic properties of the whole thin film. The morphology of the unique perylene nanotablets is significantly decided by the strictly required temperature of the depositing substrates. This approach is simple and template free and the as-prepared nanotablets possess smooth surface. The coating of the nanotablets can change the superhydrophilic surface to a superhydrophobic one which is an important application property for fabricating stable nanodevices.
