Abstract
A 55-year-old male patient presenting with 6 months of bilateral difficulty in eye opening was referred to the ophthalmology department. Upon examination, multiple yellowish tumor-like plaques and nodules were observed on the eyelids and chest of the patient, accompanied by keratitis and iridocyclitis. Histopathological examination of the skin lesions on the chest revealed dermal xanthomatous granulomas with progressive necrosis. Bone marrow biopsy showed mantle cell lymphoma. Based on the medical history, the diagnosis of progressive necrotizing xanthogranuloma with mantle cell lymphoma was confirmed. After 6 months of treatment with bendamustine combined with rituximab, there was partial alleviation of ocular symptoms in the patient.

Abstract
Objective We investigated the clinical characteristics, fall outcomes, and related factors of falls in patients who were hospitalized in the rehabilitation department, and explored strategies to reduce the incidence of falls and prevent falls in patients. Methods Data from 60 patients who fell in the rehabilitation department between 2016 and 2021 were analyzed for clinical characteristics, associated factors, incidence of falls, injuries, and patient demographics. Under the random stratified sampling method, 60 patients who did not fall during the same period were selected as the control group, and relevant data was collected. Measurement data were compared using an independent sample t-test. Enumeration data were compared using chi-squared (χ2) test was employed to compare these data between the two groups. Non-parametric data were analyzed using the Mann-Whitney U-test. Factors potentially influencing falls were scrutinized through both univariate and binary logistic regression analyses. Results The median annual incidence of falls among patients who were hospitalized in the rehabilitation department was 0.04%, while the overall fall injury rate was 60%. Falls were most prevalent within 30 days of hospitalization (71.67%). The most common fall-related condition was craniocerebral disease (83.33%). The incidents of falls location of fall were mainly reported in nearby areas of rehabilitation ward (70%). Most accidents occurred between 7:00 a.m.-12:00 p.m. and 3:01 p.m.-6:00 p.m. (63.33%), and dyskinesia was the most common cause of falls (71.67%). There were 39 patients (65.00%) with Barthel Index (BI) scores ranging between 40-60. Conclusion Patients in the rehabilitation department had a greater incidence of falls and fall injuries. Within 30 days of admission, patients with moderately dependent craniocerebral disorders and dyskinesia frequently experienced falls during typical daytime shifts in areas characterized by endemic conditions.

Abstract
Objective: To investigate the clinical features and prognosis of testicular relapse in pediatric acute lymphoblastic leukemia (ALL). Methods: Clinical data including the age, time from initial diagnosis to recurrence, relapse site, and therapeutic effect of 37 pediatric ALL with testicular relapse and treated in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences between November 2011 and December 2022 were analyzed retrospectively. Patients were grouped according to different clinical data. Kaplan-Meier analysis was used to evaluate the overall survival (OS) rate and event free survival (EFS) rate for univariate analysis, and Cox proportional-hazards regression model was used to evaluate the influencing factors of OS rate and EFS rate for multivariate analysis. Results: The age at initial diagnosis of 37 pediatric testicular relapse patients was (5±3) years and the time from initial diagnosis to testicular recurrence was (37±15) months. The follow-up time was 43 (22, 56) months. Twenty-three patients (62%) were isolated testis relapse. The 5-year OS rate and EFS rate of the 37 relapsed children were (60±9) % and (50±9) % respectively. Univariate analysis showed that the 2-year EFS rate in the group of patients with time from initial diagnosis to testicular recurrence >28 months was significantly higher than those ≤28 months ((69±10)% vs. (11±11)%, P<0.05), 2-year EFS rate of the isolated testicular relapse group was significantly higher than combined relapse group ((66±11)% vs. (20±13) %, P<0.05), 2-year EFS rate of chimeric antigen receptor T (CAR-T) cell treatment after relapse group was significantly higher than without CAR-T cell treatment after relapse group ((78±10)% vs. (15±10)%, P<0.05). ETV6-RUNX1 was the most common genetic aberration in testicular relapsed ALL (38%, 14/37). The 4-year OS and EFS rate of patients with ETV6-RUNX1 positive were (80±13) % and (64±15) %, respectively. Multivariate analysis identified relapse occurred≤28 months after first diagnosis (HR=3.09, 95%CI 1.10-8.72), combined relapse (HR=4.26, 95%CI 1.34-13.52) and CAR-T cell therapy after relapse (HR=0.15,95%CI 0.05-0.51) were independent prognostic factors for 2-year EFS rate (all P<0.05). Conclusions: The outcome of testicular relapse in pediatric ALL was poor. They mainly occurred 3 years after initial diagnosis. ETV6-RUNX1 is the most common abnormal gene.Patients with ETV6-RUNX1 positive often have a favorable outcome. Early relapse and combined relapse indicate unfavorable prognosis, while CAR-T cell therapy could significantly improve the survival rate of children with testicular recurrence.

Abstract
To explore screening tools for children with autism spectrum disorder (ASD), which are convenient for primary hospitals, it can provide basic data for formulating ASD prevention policies. This was a cross-sectional study by cluster sampling. Huyi District and Xincheng District were extracted for investigation in Xi'an City. From July 2021 to September 2022, all children aged from 3 months to 36 months who live in the two districts were subjected to primary screening. The child care physician used the routine screening tool "warning signs checklist for screening psychological, behavioral and developmental problems of children" and cartoon pictures of "early high-risk warning signs of autism", the children who were positive in the initial screening were referred to the district level maternal and child health hospital for re-screening, and those who were positive in the re-screening were referred to Xi 'an Children's Hospital for diagnosis. The results showed that a total of 17 905 children aged from 3 months to 36 months were initially screened in the two districts, including 10 588 children aged from 18 months to 36 months, 50 children who were positive in the initial screening and 50 children who were re-screened. 23 children (18 boys and 5 girls) were diagnosed with ASD. The prevalence rate of ASD in children was 2.17‰ (95% confidence interval:1.29‰-3.06‰). 42 children were positive for "warning signs checklist" at the preliminary screening, and 19 were confirmed as ASD. 27 children were positive for "cartoon pictures" in the preliminary screening, and 23 were confirmed with ASD. The "cartoon pictures" in the preliminary screening and diagnosis of consistent rate was higher than the "warning signs checklist", two kinds of screening methods comparison were statistically significant difference in the odds of consistent (χ2=11.01, P=0.001). In conclusion, relying on the three-level network of maternal and child health care, it is conducive to the whole process management of screening and diagnosis of children with ASD, and to guide the formulation of prevention policies. The cartoon pictures of "early high-risk warning signs of autism" can assist the identification of children with ASD based on the "warning signs checklist", which is simple, effective and suitable for promotion in the community health care.

Abstract
Objective: To describe the gene mutation profile of newly diagnosed pediatric B-acute lymphoblastic leukemia (B-ALL) and analyze its effect on minimal residual disease (MRD). Methods: A total of 506 newly diagnosed B-ALL children treated in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences from September 2018 to July 2021 were enrolled in this retrospective cohort study. The enrolled children were divided into MRD ≥1.00% group and <1.00% group according to MRD results on the 19th day since chemotherapy, and MRD ≥0.01% group and <0.01% group according to MRD results on the 46th day. Clinical characteristics and gene mutations of two groups were compared. Comparisons between groups were performed with chi-square test or Fisher's exact test. Independent risk factors of MRD results on the 19th day and the 46th day were analyzed by Logistic regression model. Results: Among all 506 patients, there were 318 males and 188 females. On the 19th day, there were 114 patients in the MRD ≥1.00% group and 392 patients in the MRD <1.00% group. On the 46th day, there were 76 patients in the MRD ≥0.01% group and 430 patients in the MRD <0.01% group. A total of 187 gene mutations were detected in 487 (96.2%) of 506 children. The most common gene mutations were signal transduction-related KRAS gene mutations in 111 cases (22.8%) and NRAS gene mutations in 99 cases (20.3%). Multivariate analysis showed that PTPN11 (OR=1.92, 95%CI 1.00-3.63), KMT2A (OR=3.51, 95%CI 1.07-11.50) gene mutations and TEL-AML1 (OR=0.48, 95%CI 0.27-0.87), BCR-ABL1 (OR=0.27, 95%CI 0.08-0.92) fusion genes and age >10 years (OR=1.91, 95%CI 1.12-3.24) were independent influencing factors for MRD ≥1.00% on the 19th day. BCORL1 (OR=2.96, 95%CI 1.18-7.44), JAK2 (OR=2.99, 95%CI 1.07-8.42) and JAK3 (OR=4.83, 95%CI 1.50-15.60) gene mutations and TEL-AML1 (OR=0.43, 95%CI 0.21-0.87) fusion gene were independent influencing factors for MRD ≥0.01% on the 46th day. Conclusions: Children with B-ALL are prone to genetic mutations, with abnormalities in the RAS signaling pathway being the most common. Signal transduction related PTPN11, JAK2 and JAK3 gene mutations, epigenetic related KMT2A gene mutation and transcription factor related BCORL1 gene mutation are independent risk factors for MRD.

Abstract
Objective: Based on a cohort and intervention study of the Eastern Chinese Student Surveillance, Cohort and Intervention Study (ES-SCI), this research aims to explore the correlation between monitor of the school environment and longitudinal data on myopia and provide evidence for the government myopia intervention strategy. Methods: This survey adopts the stratified cluster sampling method with the school as the unit. Students from grade 1 to grade 3 were selected according to the whole class to monitor the school environment in the classroom. Students will use the full-automatic computer optometer (TOPCON RM800) to conduct optometry from 2019 to 2021 under the condition of mydriasis to perform refractive eye examinations. Meantime eye axis length monitoring was also conducted. Cox proportional risk regression model was used to explore the relationship between school environmental monitoring and the occurrence and development of students' myopia. Results: From 2019 to 2021, 2 670 students from 77 classrooms participated in the observation study. The students' diopter after right/left eye mydriasis decreased in varying degrees (P<0.001), and the axial length of the right/left eye increased in various degrees (P<0.001). The weighted qualified rate of per capita area of primary school classrooms increased from 18.0% in 2019 to 26.0% in 2021, the weighted average illuminance pass rate of blackboard surface increased from 23.8% in 2019 to 26.4% in 2021, and the weighted average illuminance pass rate of classroom table decreased from 86.7% in 2019 to 77.5% in 2021. The trend chi-square test was significant (P<0.05). Cox proportional risk regression showed that after correcting for the grade, gender, parental myopia, diet, sleep, near work (sitting posture, working time, electronic mobile equipment, eye exercises), and outdoor activities, the per capita area of 1.36- m2 was the protective factor of eye axis length (HR=0.778, 95%CI: 0.659-0.918, P=0.003); The average reflection ratio of blackboard 0.15-0.19 was the protective factor of eye axis length (HR=0.685, 95%CI: 0.592-0.793, P<0.001); The average illumination of the blackboard 150-, 300-, 500- lx was the protective factor of the eye axis length (HR=0.456, 95%CI: 0.534-0.761, P<0.001; HR=0.794, 95%CI: 0.705-0.895, P<0.001; HR=0.690, 95%CI: 0.619-0.768, P<0.001). The blackboard evenness 0.40-0.59 was the risk factor of eye axis length (HR=1.528, 95%CI: 1.018-2.293, P=0.041), and the blackboard evenness 0.80- was the protection factor of eye axis length (HR=0.542, 95%CI: 0.404-0.726, P<0.001). The evenness of the desktop 0.40-0.59 was the protective factor of eye axis length (HR=0.820, 95%CI: 0.698-0.965, P=0.017). The average illuminance of 150-, 300-, 500- lx was the protective factor of a diopter (HR=0.638, 95%CI: 0.534-0.761, P<0.001; HR=0.911, 95%CI: 0.848-0.978, P=0.011; HR=0.750, 95%CI: 0.702-0.801, P<0.001). The average illumination of desktop 500- lx was a protective factor of a diopter (HR=0.855, 95%CI: 0.763-0.958, P=0.007). Conclusion: School environmental monitoring indicators, such as meeting per capita area standards, passing blackboard, and desk top-related indicators, all play protective effects on myopia development in students.

Abstract
Objective: To investigate the clinical features, treatment regime, and outcome of pediatric acute myeloid leukemia (AML) with DEK-NUP214 fusion gene. Methods: The clinical data, genetic and molecular results, treatment process and survival status of 7 cases of DEK-NUP214 fusion gene positive AML children admitted to the Pediatric Blood Diseases Center of Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences from May 2015 to February 2022 were analyzed retrospectively. Results: DEK-NUP214 fusion gene positive AML accounted for 1.02% (7/683) of pediatric AML diagnosed in the same period, with 4 males and 3 females. The age of disease onset was 8.2 (7.5, 9.5) years. The blast percentage in bone marrow was 0.275 (0.225, 0.480), and 6 cases were M5 by FAB classification. Pathological hematopoiesis was observed in all cases except for one whose bone marrow morphology was unknown. Three cases carried FLT3-ITD mutations, 4 cases carried NRAS mutations, and 2 cases carried KRAS mutations. After diagnosis, 4 cases received IAE induction regimen (idarubicin, cytarabine and etoposide), 1 case received MAE induction regimen (mitoxantrone, cytarabine and etoposide), 1 case received DAH induction regimen (daunorubicin, cytarabine and homoharringtonine) and 1 case received DAE induction regimen (daunorubicin, cytarabine and etoposide). Complete remission was achieved in 3 cases after one course of induction. Four cases who did not achieved complete remission received CAG (aclarubicin, cytarabine and granulocyte colony-stimulating factor), IAH (idarubicin, cytarabine and homoharringtonine), CAG combined with cladribine, and HAG (homoharringtonine, cytarabine and granulocyte colony-stimulating factor) combined with cladribine reinduction therapy, respectively, all 4 cases reached complete remission. Six patients received hematopoietic stem cell transplantation (HSCT) after 1-2 sessions of intensive consolidation treatment, except that one case was lost to follow-up after complete remission. The time from diagnosis to HSCT was 143 (121, 174) days. Before HSCT, one case was positive for flow cytometry minimal residual disease and 3 cases were positive for DEK-NUP214 fusion gene. Three cases accepted haploid donors, 2 cases accepted unrelated cord blood donors, and 1 case accepted matched sibling donor. The follow-up time was 20.4 (12.9, 53.1) months, the overall survival and event free survival rates were all 100%. Conclusions: Pediatric AML with DEK-NUP214 fusion gene is a unique and rare subtype, often diagnosed in relatively older children. The disease is characterized with a low blast percentage in bone marrow, significant pathological hematopoiesis and a high mutation rate in FLT3-ITD and RAS genes. Low remission rate by chemotherapy only and very high recurrence rate indicate its high malignancy and poor prognosis. Early HSCT after the first complete remission can improve its prognosis.

Abstract
Background During autophagy defense against invading microbes, certain lipid types are indispensable for generating specialized membrane-bound organelles. The lipid composition of autophagosomes remains obscure, as does the issue of how specific lipids and lipid-associated enzymes participate in autophagosome formation and maturation. Helicobacter pylori is auxotrophic for cholesterol and converts cholesterol to cholesteryl glucoside derivatives, including cholesteryl 6ʹ-O-acyl-α-d-glucoside (CAG). We investigated how CAG and its biosynthetic acyltransferase assist H. pylori to escape host-cell autophagy. Methods We applied a metabolite-tagging method to obtain fluorophore-containing cholesteryl glucosides that were utilized to understand their intracellular locations. H. pylori 26695 and a cholesteryl glucosyltransferase (CGT)-deletion mutant (ΔCGT) were used as the standard strain and the negative control that contains no cholesterol-derived metabolites, respectively. Bacterial internalization and several autophagy-related assays were conducted to unravel the possible mechanism that H. pylori develops to hijack the host-cell autophagy response. Subcellular fractions of H. pylori-infected AGS cells were obtained and measured for the acyltransferase activity. Results The imaging studies of fluorophore-labeled cholesteryl glucosides pinpointed their intracellular localization in AGS cells. The result indicated that CAG enhances the internalization of H. pylori in AGS cells. Particularly, CAG, instead of CG and CPG, is able to augment the autophagy response induced by H. pylori. How CAG participates in the autophagy process is multifaceted. CAG was found to intervene in the degradation of autophagosomes and reduce lysosomal biogenesis, supporting the idea that intracellular H. pylori is harbored by autophago-lysosomes in favor of the bacterial survival. Furthermore, we performed the enzyme activity assay of subcellular fractions of H. pylori-infected AGS cells. The analysis showed that the acyltransferase is mainly distributed in autophago-lysosomal compartments. Conclusions Our results support the idea that the acyltransferase is mainly distributed in the subcellular compartment consisting of autophagosomes, late endosomes, and lysosomes, in which the acidic environment is beneficial for the maximal acyltransferase activity. The resulting elevated level of CAG can facilitate bacterial internalization, interfere with the autophagy flux, and causes reduced lysosomal biogenesis.

Abstract
目的 探讨异基因造血干细胞移植(allo-HSCT)患儿造血重建后人类细小病毒B19(HPV-B19)感染的血液学表现。 方法 对9例allo-HSCT后合并HPV-B19感染的患儿进行回顾性分析。 结果 9例患儿占同期接受allo-HSCT患儿的8.04%(9/112),男8例,女1例,中位年龄9(3~13)岁,均采取清髓性预处理方案。HPV-B19感染中位时间为移植后61(36~114)d。allo-HSCT并发HPV-B19感染患儿血液学表现具有异质性,9例患儿以血红蛋白伴网织红细胞下降为主要特点,7 d内网织红细胞比例、绝对值下降幅度中位数分别为90.4%(24.7%~98.7%)、90.7%(18.6%~99.0%)。除常见红系造血停滞表现外,allo-HSCT后合并HPV-B19感染的患儿还具有非红系的血象及骨髓变化:5例患儿外周血出现中性粒细胞下降,但骨髓涂片未见粒系增生受抑;6例患儿骨髓涂片查见巨核系增生减低,其中5例患儿外周血血小板下降。同时,allo-HSCT造血重建后合并HPV-B19感染的患儿骨髓红系受抑并非必要表现,9例患儿虽然均出现血红蛋白下降,但仅5例患儿骨髓红系增生减低。 结论 血液病患儿allo-HSCT造血重建后合并HPV-B19感染的血液学表现具有异质性,血红蛋白伴网织红细胞下降对HPV-B19感染早期诊断可能具有重要意义。

Abstract
Objective: To explore the clinical features of bloodstream infections (BSI) in children with acute myeloid leukemia (AML) during the first induction chemotherapy. Methods: The clinical data, pathogen of BSI, antibiotic susceptibility in vitro, complications and prognosis of 204 newly diagnosed AML children admitted to Blood Diseases Hospital, Chinese Academy of Medical Sciences from August 2009 to December 2015 were analyzed retrospectively. χ2 test was used for the comparison between groups and Logistic regression was used for BSI risk factor analysis. Results: Among 204 patients, 116 were males and 88 were females. The age was 8 (ranged from 1 to 14) years. Among them, 170 patients received MAE chemotherapies (etoposide, mitoxantrone and cytarabine) and 25 received IAE chemotherapies (etoposide, idarubicin and cytarabine). The other 9 patients used granulocyte colony stimulating factor (G-CSF)-priming regimen (aclacinomycin or homoharringtonine, cytarabine and G-CSF) for induction treatments. A total of 28 patients experienced BSI and the incidence rate was 13.7% (28/204), 26 of them developed BSI once and 2 patients developed twice. Gram-positive bacteria were predominant pathogens accounting for 53.3% (16/30) while gram-negative bacteria accounting for 40.0% (12/30) and fungal accounted for 6.7% (2/30). The most common detected pathogens were Coagulase negative Staphylococcus (CoNS, 26.7% (8/30)), followed by Streptococcus spp. (13.3% (4/30)) and Escherichia coli (13.3% (4/30)). Among Gram-negative bacteria (GNB), 3 cases showed carbapenem resistance and 2 cases were Stenotrophomonas maltophilia. BSI-related mortality was 28.6% (8/28). Infections caused by drug-resistant GNB or fungi resulted in 6 fatal cases. The incidence rate of BSI in group with severe neutropenia was higher than in group without it (16.6% (25/151) vs. 5.7% (3/53), χ²=3.933, P=0.047). Multivariable analysis showed severe neutropenia at the onset of fever was independent risk factor of BSI (OR=4.258,95%CI 1.097-16.524,P=0.036). Conclusions: During the first induction chemotherapy courses, Gram-positive bacteria cause most of the BSI. Drug-resistant bacteria related infection often result in fatal outcomes. Severe neutropenia is a significant risk factor.

Abstract
Objective: To compare the efficacy and safety of Changsulin® with Lantus® in treating patients with type 2 diabetes mellitus (T2DM). Methods: This was a phase Ⅲ, multicenter, randomized, open-label, parallel-group, active-controlled clinical trial. A total of 578 participants with T2DM inadequately controlled on oral hypoglycemic agents were randomized 3∶1 to Changsulin® or Lantus® treatment for 24 weeks. The efficacy measures included changes in glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2h postprandial plasma glucose (2hPG), 8-point self-monitoring of blood glucose (SMBG) profiles from baseline, and proportions of subjects achieving targets of HbA1c and FPG. The safety outcomes included rates of hypoglycemia, adverse events (AEs) and anti-insulin glargine antibody. Results: After 24 weeks of treatment, mean HbAlc decreased 1.16% and 1.25%, FPG decreased 3.05 mmol/L and 2.90 mmol/L, 2hPG decreased 2.49 mmol/L and 2.38 mmol/L in Changsulin® and in Lantus®, respectively. No significant differences could be viewed in above parameters between the two groups (all P>0.05). There were also no significant differences between Changsulin® and Lantus® in 8-point SMBG profiles from baseline and proportions of subjects achieving the targets of HbA1c and FPG (all P>0.05). The rates of total hypoglycemia (38.00% and 39.01% for Changsulin® and Lantus®, respectively) and nocturnal hypoglycemia (17.25% and 16.31% for Changsulin® and Lantus®, respectively) were similar between the two groups (all P>0.05). Most of the hypoglycemia events were asymptomatic, and no severe hypoglycemia were found in both groups. No differences were observed in rates of AEs (61.77% vs.52.48%) and anti-insulin glargine antibody (after 24 weeks of treatment, 6.91% vs.3.65%) between the two groups (all P>0.05). Conclusions: Changsulin® shows similar efficacy and safety profiles compared with Lantus® and Changsulin® treatment was well tolerated in patients with T2DM.

Abstract
Objective: To evaluate the predictive role of ETV6-RUNX1 fusion gene in protocol CCLG-ALL-2008 as well as identify the prognostic factors that influence the outcome of ALL with ETV6-RUNX1 fusion gene. Methods: One hundred and seventy-eight patients newly diagnosed with pediatric acute lymphoblastic leukemia with ETV6-RUNX1 rearrangement from April 2008 to April 2015 were enrolled in CCLG-ALL-2008. The follow up period ended in July 2018; we performed retrospective analyses of their data to determine the efficacy of the regimen and the prognostic factors. Results: The median age of the study population (178 pediatric patients) , including 100 boys and 78 girls was 4 (1-13) y, and the median white blood cell count at diagnosis was 9.46 (1.25-239.83) ×10(9)/L. Three patients died, and 1 was lost to follow up by the end of the first induction chemotherapy, resulting in an induced remission rate of 97.8% (174/178) . The cumulative incidence of relapse was 15.9% with a median follow up of 73.5 mon. Total 83.3% of the relapse cases were those of isolated bone marrow relapse, while 79.2% of the cases were those of late relapse. The median interval time between relapse and first complete remission was 35.5 mon (range, 1-62 months) . One of the 5 patients with early recurrence and 7 of the 19 with late recurrence cases survived. The 5-year-OS and 5-year-EFS of ETV6-RUNX1 positive children was (89.4±2.4) % and (82.1±6.9) %, respectively. The estimated 10-year-OS and 10-year-EFS of ETV6-RUNX1 positive children was (88.6±2.5) % and (77.3±4.0) %, respectively. The Kaplan-Meier method and Log-rank test were used to estimate and compare the survival. Univariate statistical analysis showed that poor prognostic factors that influenced survival included central nervous system state 2 at diagnosis, poor prednisone response, high risk, gene positivity after induction chemotherapy, as well as MRD positivity and gene positivity at the 12(th) week. In the multivariate analysis, only the central nervous system state 2 at diagnosis and MRD positivity at the 12(th) week were associated with the outcome. Conclusion: ETV6-RUNX1-positive ALL is a subgroup with a favorable prognosis as per the CCLG-ALL-2008 protocol. Patients with ETV6-RUNX1 should be given more intensive therapy, including hematopoietic stem cell transplantation when they are CNS2 at diagnosis or have high level of MRD at the 12(th) week after treatment.

Abstract
Objective: To evaluate the efficacy of the Chinese Children's Leukemia Group (CCLG) acute lymphoblastic leukemia (ALL) 2008 protocol (CCLG-ALL 2008) in the treatment of children's T-cell acute lymphoblastic leukemia (T-ALL). Methods: Clinical characteristics and outcomes of 84 newly diagnosed T-ALL children (63 males and 21 females) treated with CCLG-ALL 2008 protocol from April 2008 to April 2015 in the Department of Pediatric Hematology, Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences were analyzed retrospectively. Kaplan-Meier analysis was used to evaluate the overall survival (OS) and event free survival (EFS), and COX regression was used to evaluate the influencing factors of OS and EFS. Results: (1) Baseline data: 84 children were included, 56 cases (67%) of children were younger than 10 years old. Patients whose white blood cell count≥50×10(9)/L ranked 70% (59/84). Karyotype: 58% (49/84) with normal karyotype, 10% (8/84) with abnormality of chromosome 11, 8%(7/84) with abnormality of chromosome 9, 2%(2/84) with abnormality in both chromosome 11 and chromosome 9, 8% (7/84) with other complex karyotypes. Fusion gene: 33%(28/84) were SIL-TAL1 positive. The patients were grouped by CCLG-ALL 2008 risk score, 40% (34/84) were in the intermediate risk group and 60% (50/84) in the high risk group. (2) Treatment efficacy: 84 cases were followed up until May 30, 2018. The follow-up time was 42.0 (0.3-120.0) months. The sensitivity rate of prednisone treatment was 56% (47/84); the complete response (CR) rate after the induction therapy of vincristine+daunoblastina+L-asparaginase+dexamethasone (VDLD)(d 33) was 88% (74/84); the total CR rate after VDLD induction combined with cyclophosphamide+cytarabine+6-mercaptopurine (CAM) treatment (d80) was 94% (79/84); the recurrence rate was 24% (20/84). Among the 20 recurrent cases, there were 13 cases (65%) with ultra-early recurrence (within 18 months after diagnosis), 6 cases (30%) with early recurrence (18 to 36 months after diagnosis); 1 patient (5%) with late recurrence (over 36 months after diagnosis). During the follow-up period, twenty-eight children (33%) died (22 cases with recurrence or suspending treatment without remission, 2 cases with infection, 1 case of sudden death in chemotherapy, 1 patient failed in transplantation, 1 patient with severe cirrhosis, and 1 patient with unknown cause). (3) Kaplan-Meier analysis: the 5-year OS and EFS of the 84 children were (63±6)% and (60±6)% respectively. (4) Efficacy in different risk groups: prednisone sensitivity rates in the two different risk groups were 100% (34/34) and 26% (13/50), respectively (χ(2)=3.237, P<0.05). The CR rates at the end of VDLD induction therapy (d 33) were 100% (34/34) and 80% (40/50), respectively (χ(2)=2.767, P<0.05). The recurrence rate of children in the two groups was 12% (4/34) and 32% (16/50), respectively (χ(2)=4.245, P<0.05).The mortality rates of the two groups were 21% (7/34) and 42% (21/50), respectively (χ(2)=3.198, P<0.05). Kaplan-Meier analysis showed that the 5-year OS of the two groups were (77±7)% and (53±8)%; and the 5-year EFS of the two groups were (75±8)% and (49±8)% (χ(2)=4.235, 3.875, both P<0.05) . (5) COX multivariate regression analysis showed that the classification of risk according to CCLG-ALL 2008 was an important factor influencing the prognosis of children with T-ALL (OR=3.313, 95% CI 1.165-9.422, P=0.025). Conclusions: The results of the risk group treatment according to the CCLG-ALL 2008 protocol showed that the long-term survival of children with middle risk was significantly better than that of children at high risk.

Abstract
Abstract
Rationale
Tools reflecting molecular processes predicting death after discharge from intensive care unit (ICU) are currently unavailable.
Objectives
To construct a urinary proteomic biomarker predicting 1-year post-ICU mortality.
Methods
In 1081 patients, enrolled in the French and European Outcome Registry in Intensive Care Unit (NCT01367093), the urinary proteome was measured at ICU discharge using capillary electrophoresis couple with mass spectrometry along with clinical variables; circulating biomarkers (NT-proBNP, hsTnT, biologically active adrenomedullin, soluble ST2, and NGAL) and urinary albumin were available in 886 patients.
Measurements and main results
In the discovery sample (60/256 deaths/survivors), support vector machine modelling identified ACM150, mainly consisting of collagen fragments, yielding an AUC of 0.676 (95% CI, 0.615–0.737). In the replication sample (151/608 deaths/survivors), AUC was 0.704 (0.659–0.750). While accounting for center and clinical risk factors, the hazard ratios in all available patients were 1.27 (1.18–1.37) for ACM150 (+1 SD), 1.20 (1.16–1.33) for the Charlson score (+1 point), and ≥1.30 (P≤0.0071) for the other biomarkers (+ 1 SD). Model performance assessed by adding ACM150 to a basic model including the aforementioned covariables, the Charlson score or any other biomarker confirmed the prognostic accuracy of ACM15 with significant increases (P≤0.0038) in integrated discrimination (≥ +0.50) and net reclassification improvement (≥ +53.7) and AUC (≥ +0.037). Interactome mapping (STRING) based on 72 sequenced peptides and 25 parental proteins gravitated around collagen nodes.
Conclusions
ACM150 is a urinary proteomic classifier predicting 1-year post-ICU mortality over and beyond other biomarkers and reflects dysregulation of collagen turnover as underlying pathophysiological process.

Abstract
When plants are exposed to a heterogeneous environment, photosynthesis of leaves is not only determined by their local condition, but also by certain signals from other parts of the same plant, termed systemic regulation. Our present study was conducted to investigate the effects of light-dependent systemic regulation on the photosynthetic performance of soybean (Glycine max L. Merr.) under heterogeneous light conditions. Soybean plants were treated with heterogeneous light. Then gas exchange characteristics were measured to evaluate the photosynthetic performance of leaves. Parameters related to photosynthetic pigments, chlorophyll fluorescence, Rubisco and photosynthates were examined to study the mechanisms of light-dependent systemic regulation on photosynthesis. Light-induced systemic signalling by illuminated leaves reduced the Pn of both upper and lower non-illuminated leaves on the same soybean plant. The decrease in gs and increase in Ci in these non-illuminated leaves indicated restriction of carbon assimilation, which was further verified by the decline in content and activity of Rubisco. However, the activation state of Rubisco decreased only in upper non-illuminated leaves. Quantum efficiency of PSII (ΦPSII) and ETR also decreased only in upper non-illuminated leaves. Moreover, the effects of light-induced systemic signalling on carbohydrate content were also detectable only in upper non-illuminated leaves. Light-induced systemic signalling by illuminated leaves restricts carbon assimilation and down-regulates photosynthetic performance of non-illuminated leaves within a soybean plant. However, effects of such systemic regulation differed when regulated in upward or downward direction.

Abstract
Objective: To clarify the prevalence, clinical features and molecular characteristics of germline GATA2 mutations in pediatric primary myelodysplastic syndromes (MDS) . Methods: Next-generation sequencing technology was used to detect mutations in GATA2 and other myeloid malignancy genes in 129 children with primary MDS from Jan. 2007 to Jan. 2018. The relationship between genotypes and phenotypes was analyzed. Results: Germline GATA2 mutations accounted for 8.5% (11/129) of all primary MDS cases, and 14.0% (11/50) of MDS with excess blasts (MDS-EB) and acute myeloid leukaemia with myelodysplasia-related changes (AML-MRC) . Compared with GATA2 wild-type patients, GATA2 mutated patients were older at diagnosis[8 (1-16) years old vs 6 years old (range: 1 month old-18 years old) , P=0.035]and higher risk of monosomy 7 (72.7%vs 5.2%, P<0.001) and classified into MDS-EB and AML-MRC compared with refractory cytopenia of childhood (RCC) (63.6%vs 36.4%, P=0.111) . The multivariate analysis showed SETBP1 mutation (P=0.041, OR=9.003, 95%CI 1.098-73.787) and isolated monosomy 7 (P=0.002, OR=24.835, 95%CI 3.305-186.620) were significantly associated with germline mutated GATA2. Overall survival (OS) and outcomes of hematopoietic stem cell transplantation (HSCT) were not influenced by GATA2 mutational status. Conclusions: Our data identify germline GATA2 mutations have a high prevalence in older pediatric patients with monosomy 7, and high risk of progression into advanced MDS subtypes. GATA2 mutation status does not affect OS in pediatric primary MDS.

Abstract
Objective: Curcumin was used as photosensitizers in photodynamic therapy on cervical cancer xenografts in nude mice.Analysis the expression changes of Notch and downstream gene as NF-κB and VEGF before and after DAPT inhibition of Notch signaling pathway in vivo experiments.Our aim was to investigate the possible mechanism of Notch signaling pathway in the treatment of cervical cancer with PDT. Methods: A cervical cancer model of nude mice was established by subcutaneous inoculation of human cervical cancer Me180 cells 200 μl.After the success of the model, the experimental animals were divided into 4 groups (model group, curcumin PDT group, simple DAPT group, curcumin-PDT+ DAPT group), each group was 12.Tumor volume changes were analyzed and HE staining was observed in each group.MRNA and protein expression of Notch1 and its downstream NF-κB, VEGF were detected by RT-PCR, immunohistochemistry and Western blot before and after inhibition of Notch signaling pathway by DAPT. Results: Except the control group, the tumor volume of the other three groups remained unchanged or slightly reduced after 1-7 days of treatment.The difference was significant (P<0.05). HE staining showed the most obvious necrosis of curcumin-PDT group with DAPT.Both DAPT and curcumin-PDT could reduce the expression level of Notch1 in mRNA.The inhibition rates were 42.17% and 40.54%, respectively.And the inhibitory effect of curcumin-PDT with DAPT on Notch-1 was the strongest (79.22%) (P<0.01), and two of them had synergistic effect after combination with curcumin-PDT.But the expression of Notch-2 has no obvious inhibitory effect (P>0.05). Both DAPT and curcumin-PDT can inhibit the protein expression of Notch1, NF-κB and VEGF, and two of them have synergistic effect after combined use. Conclusions: DAPT can effectively block the Notch signaling pathway and inhibit the proliferation of cervical cancer cell line Me180.The application of DAPT to inhibit Notch signaling pathway after photodynamic therapy can achieve synergistic effect, which is mainly related to the down-regulation of the expression of Notch1 and NF-κB.Notch signaling pathway may be one of the targets of curcumin-PDT photodynamic therapy.

Abstract
Lysophagy belongs to one of the many pathways cells activate in response to lysosomal damage. Damaged lysosomes attract glycan-binding galectins, become ubiquitinated, and are later on targeted for engulfment and degradation through lysophagy. Many triggers that are known to cause lysosomal membrane permeabilization have all been shown to induce lysophagy and can therefore be used to construct platforms for further molecular-level characterization of this process. In this chapter, we describe experimental parameters for triggering lysophagy through combined use of lysosome-specific dyes and light illumination. Within single cells, this optogenetic scheme allows easy manipulation on the amount of lysosomes to be impaired, the degree of damage desired, as well as when and where this should happen. On the other hand it can also be used to target all lysosomes within the entire cell population of a culture, allowing screening or bulk biochemical analyses to be carried out. The methodology will find use not only in monitoring lysophagy but also in probing lysosome damage responses in general.

Abstract
Objective: To analyze the clinical characteristics and prognosis of non-severe aplastic anemia (NSAA) with chromosomal abnormalities in children. Method: A retrospective analysis of 304 cases with NSAA with successful karyotyping from 2001 to 2014 in the Institute of Hematology & Blood Disease Hospital was carried out. The treatment response, condition of blood transfusion were analyzed using χ2 test, the cumulative survival was estimated by the Kaplan-Meier method. Result: Out of 304 patients, 28 patients had chromosomal abnormalities with trisomy 8 (7 cases, 25.0%), abnormalities in chromosome 7 (5 cases, 17.9%), and other types (16 cases, 57.1%). There were no significant differences in the treatment response(40.9% (9/22)vs. 58.6%(119/203), χ2=2.539, P=0.111), the rate of getting rid of blood transfusion(54.5%(6/11) vs. 65.0%(39/60), χ2=6.455, P=0.086), five-year progression-free survival (49.2% vs.70.8%, χ2=0.849, P=0.357), and five-year cumulative survival (79.1% vs. 92.8%, χ2=0.330, P=0.556) between the patients with or without chromosomal abnormalities. There were significant differences in the rate of disease progression(41.7%(10/24) vs. 22.3%(48/215), χ2=4.394, P=0.045), the incidence of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) (20.8%(5/24)vs. 0.9%(2/215), χ2=30.082, P=0.000)and the five-year cumulative incidence of MDS or AML(33.4% vs. 0.8%, χ2=17.798, P=0.000)between children with and without chromosomal abnormalities. Conclusion: The incidence of chromosomal abnormalities in children with NSAA is 9.2%. The clinical features and treatment response are similar, but children with chromosomal abnormalities have a poorer prognosis, and have higher risk of progressing to MDS or AML.

Abstract
BACKGROUND Childhood obesity is becoming more common as Malaysia experiences rapid nutrition transition. Current evidence related to parental influences on child dietary intake and body weight status is limited. The present study aimed to report, among Malay families, the prevalence of energy mis-reporting and dietary relationships within family dyads. METHODS The cross-sectional Family Diet Study (n = 236) was conducted at five primary schools in central of Peninsular Malaysia. Each family consisted of a Malay child, aged 8-12 years, and their main caregiver(s). Information on socio-demographics, dietary intake and anthropometry were collected. Correlations and regression analyses were used to assess dietary relationships within family dyads. RESULTS Approximately 29.6% of the children and 75.0% parents were categorised as being overweight or obese. Intakes of nutrients and food groups were below the national recommended targets for majority of children and adults. A large proportion of energy intake mis-reporters were identified: mothers (55.5%), fathers (40.2%) and children (40.2%). Children's body mass index (BMI) was positively associated with parental BMI (fathers, r = 0.37; mothers, r = 0.34; P < 0.01). For dietary intakes, moderate-to-strong (0.35-0.72) and weak-to-moderate (0.16-0.35) correlations were found between mother-father and child-parent dyads, respectively. Multiple regression revealed that maternal percentage energy from fat (β = 0.09, P < 0.01) explained 81% of the variation in children's fat intake. CONCLUSIONS Clear parental dietary relationships, especially child-mother dyads, were found. Despite a significant proportion of families with members who were overweight or obese, the majority reported dietary intakes below recommended levels, distorted by energy mis-reporting. The findings of the present study can inform interventions targeting parent-child relationships to improve family dietary patterns in Malaysia.

Abstract
Our study aimed to investigate the association between multidrug resistance (MDR1) gene polymorphisms and the response to imatinib (IM) in chronic myeloid leukemia (CML). An electronic databases in PubMed, Cochrane Library, Wanfang, China National Knowledge Infrastructure, and VIP were searched using combinations of keywords relating to MDR1 polymorphisms and the response to IM in CML. Studies retrieved from database searches were screened using stringent inclusion and exclusion criteria. The Comprehensive Meta-analysis 2.0 software was utilized for all statistical analyses. In total, 186 studies were initially retrieved, and 10 studies, involving 987 CML patients, were eventually included in this meta-analysis. Results of our study revealed no significant associations between MDR1 rs1045642, rs1128503, and rs2032582 polymorphisms and major molecular response and complete molecular response in CML patients. Significant differences were observed in the genotype frequencies of MDR1 rs1128503 under homozygous, heterozygous, and recessive models, between CML patients sensitive and resistant to IM. A significant difference in genotype frequencies of MDR1 rs2032582 was also observed under allele, homozygous, heterozygous, and recessive models between CML patients sensitive and resistant to IM. In conclusion, based on our meta-analysis, the MDR1 polymorphisms, rs1045642, rs1128503, and rs2032582, are not directly correlated with the curative effect of IM treatment of CML patients.

Abstract
Whether seeds germinate or maintain dormancy is decided upon through very intricate physiological processes. Correct timing of these processes is most important for the plants life cycle. If moist conditions are encountered, a low dormancy level causes pre-harvest sprouting in various crop species, such as wheat, corn and rice, this decreases crop yield and negatively impacts downstream industrial processing. In contrast, a deep level of seed dormancy prevents normal germination even under favourable conditions, resulting in a low emergence rate during agricultural production. Therefore, an optimal seed dormancy level is valuable for modern mechanised agricultural systems. Over the past several years, numerous studies have demonstrated that diverse endogenous and environmental factors regulate the balance between dormancy and germination, such as light, temperature, water status and bacteria in soil, and phytohormones such as ABA (abscisic acid) and GA (gibberellic acid). In this updated review, we highlight recent advances regarding the molecular mechanisms underlying regulation of seed dormancy and germination processes, including the external environmental and internal hormonal cues, and primarily focusing on the staple crop species. Furthermore, future challenges and research directions for developing a full understanding of crop seed dormancy and germination are also discussed.

Abstract
This work develops and demonstrates a double sideband with optical carrier suppression (DSBCS) modulation scheme for a hybrid wireless and cable television system based on a phase modulator (PM) and a polarization beam splitter (PBS). A carrier suppression ratio greater than 20 dB is achieved between two sidebands. In addition, the values of carrier-to-noise ratio, composite second-order and composite triple beat in various channels after 25 km of transmission are higher than the threshold value, and the power penalty of microwave signal in back-to-back and 25 km transmission perform well. Additionally, the constellation diagram of upstream signal is successfully recovered. Above results demonstrate that the proposed scheme is highly promising for practical applications.

Abstract
Anti-neuroexcitation peptide III of Buthus martensii Karsch (BmK ANEP III) has better anti-epileptic and anticonvulsive effects in the test animal models. The present study is aimed at developing transgenic tomato and tobacco lines overproducing the ANEP III protein. Using the molecular cloning technique, the plant expression vector pBI-ANEP III was constructed successfully. The ANEP III expression cassette included a double CaMV 35S promoter with omega enhancers, the ANEP III gene with the Kozak sequence, the ER retention signal and the NOS terminator. Recombinant plasmids were transferred into Agrobacterium tumefaciens EHA105 by freeze-thaw transformation methods. By the Agrobacterium-mediated leaf disc transformation method, tobacco (Nicotiana tabacum) and tomato (Lycopersicum esculentum) lines were transformed. Transformants were screened and confirmed by PCR, RT-PCR and western blotting analysis. It was demonstrated that the ANEP III gene was successfully expressed in the genomic DNA of transgenic plants. The ANEP III protein was detected by immunofluorescence analysis, and the results confirmed the high amount of ANEP III protein, being 0.81 and 1.08% of total soluble proteins in transgenic tobacco and tomato. The study of plants with high expression levels of ANEP III has an important theoretical and practical significance and provides valuable information for establishing a new, economical and effective system for industrial protein production.

Abstract
Acquired nostril stenosis usually develops from scar contracture due to trauma or infection. The purpose of surgical repair is to emulate the lobule-columella-ala complex, anatomically reconstruct adequate nostrils and maintain long-term patency. A linear scar contracture may be released by a Y-to-V advancement technique, as part of a running Y-V plasty procedure. Nostril stenosis with a circular, linear contracture involving the columella, ala and nostril sill is difficult to correct satisfactorily by W-plasty or Z-plasty alone. We used running Y-V plasty with six triangular flaps of the Y on each external and internal surface in two cases of bilateral nostril stenosis after smallpox, a method that provides one largest external flap for the nostril sill, two external flaps for the ala and the columella each and one external flap for the soft triangle. This technique was easily designed and achieved adequate release and coverage without the use of additional local flaps, and yielded reconstructed nostrils of sufficient size. The running Y-V plasty technique is feasible for correction of nostril stenosis with linear contracture involving the entire nostril rim.

Abstract
BACKGROUND There is compelling evidence showing that achieving good glycaemic control reduces the risk of microvascular complications in people with type 1 and type 2 diabetes. Likewise, there is clear evidence to show that achieving good glycaemic control reduces the risk of macrovascular complications in type 1 diabetes. The UKPDS 10-year follow up suggests that good glycaemic control also reduces the risk of macrovascular complications in type 2 diabetes. Despite this, recent results from ACCORD, ADVANCE and VADT present conflicting results and data from the ACCORD trial appear to suggest that very low HbA(1c) targets (<6.0%) may, in fact, be dangerous in certain patient populations. AIM To review recent results from ACCORD, ADVANCE and VADT and provide clear guidance on the clinical significance of the new data and their implications for the practising physician treating patients with type 2 diabetes. METHODS A Pubmed search was used to identify major randomised clinical trials examining the association between glycaemic control and diabetes-associated complications. The data was reviewed and discussed by the GTF through a consensus meeting. The recommendations for clinical practice in this statement are the conclusions of these analyses and discussions. RESULTS Evidence from ACCORD, ADVANCE, VADT and UKPDS suggests that certain patient populations, such as those with moderate diabetes duration and/or no pre-existing CVD, may benefit from intensive blood glucose control. These trials highlight the benefit of a multifactorial treatment approach to diabetes. However, ACCORD results indicate that aggressive HbA(1c) targets (<6.0%) may not be beneficial in patients with existing CVD and a longer duration of diabetes. CONCLUSIONS Glycaemic control remains a very important component of treatment for type 2 diabetes and contrasting results from the ACCORD, ADVANCE and VADT should not discourage physicians from controlling blood glucose levels.

Abstract
Germination in sesame seeds (Sesamum indicum L.) in water and in indole-3-acetic acid (IAA) solution is investigated with magic-angle-spinning (MAS) solid state nuclear magnetic resonance (NMR) spectroscopy, supplemented by liquid state NMR spectroscopy. The spectra show good resolution and can be assigned with sufficient confidence. The characteristic spectral peaks and relaxation rates were monitored during the entire course of germination for better understanding of the biophysical and biochemical mechanisms involved in the triphasic water uptake of the seed. A highly positive correlation is found between water uptake and lipid consumption during germination. No significant variation is observed in the relaxation times for the lipid protons during the first two stages of triphasic water uptake, while evident differences are observed for water proton relaxation rates in all stages. Although the total amount of water uptake is largely not changed as a result of IAA, the addition of IAA in seed-germination medium has shown some prominent effects on the germination process, e.g, it suppresses lipid consumption and water mobility, and it reduces the longitudinal and transverse relaxation times of lipid protons and causes a more scattered range for these parameters.

Abstract
We report here the clinical, genetic, and molecular characteristics of a large Chinese family exhibiting non-syndromic, late-onset autosomal dominant sensorineural hearing loss. Clinical evaluation revealed variable phenotypes of hearing loss in terms of severity and age-at-onset of disease in these subjects. Genome-wide linkage analysis mapped the disease gene to the DFNA5 locus with a maximum two-point log odds score of 5.39 at [theta] = 0 for marker D7S2457. DNA sequencing of DFNA5 revealed a novel heterozygous IVS8+4 A>G substitution in the splice donor site of intron 8. Reverse transcriptase-polymerase chain reaction (RT-PCR) showed skipping of exon 8 in the mutant transcript. This mutation faithfully cosegregated with hearing loss in the family. In addition, the mutation was absent in 100 unrelated control DNA samples of Chinese origin. The IVS8+4 A>G mutation is predicted to create a shift in the reading frame and introduce a stop codon at position 372, thereby resulting in a prematurely truncated DFNA5 protein. Up to date, a total of four mutations in DFNA5 have been reported to lead to hearing impairment, all of them result in skipping of exon 8 at the mRNA level. Our findings provide further support for the hypothesis that DFNA5-associated hearing loss is caused by a very specific gain-of-function mutation.

Abstract
BACKGROUND We report here the genetic characterisation of a large five generation Chinese family with the phenotypic features of auditory neuropathy and progressive peripheral sensory neuropathy, and the genetic feature of X linked recessive inheritance. Disease onset was at adolescence (at an average age of 13 years for six affected subjects). The degree of hearing impairment varied from mild to severe, with decreased otoacoustic emissions; auditory brainstem responses were lacking from onset. METHODS Two-point and multipoint model based linkage analysis using the MILNK and LINKMAP programs of the FASTLINK software package produced maximum two-point and multipoint LOD scores of 2.41 and 2.41, respectively. RESULTS These findings define a novel X linked auditory neuropathy locus/region (AUNX1, Xq23-q27.3). This region is 42.09 cM long and contains a 28.07 Mb region with flanking markers DXS1220 and DXS8084, according to the Rutgers Combined Linkage-Physical Map, build 35. However, mutation screen of the candidate gene SLC6A14 within the region did not identify the causative genetic determinant for this large Chinese family.

Abstract
Stripe rust, caused by Puccinia striiformis f. sp. tritici (PST), is one of the most devastating diseases in common wheat (Triticum aestivum L.) worldwide. The objectives of this study were to map a stripe rust resistance gene in Chinese wheat cultivar Chuanmai 42 using molecular markers and to investigate its allelism with Yr24 and Yr26. A total of 787 F2 plants and 186 F3 lines derived from a cross between resistant cultivar Chuanmai 42 and susceptible line Taichung 29 were used for resistance gene tagging. Also 197 F2 plants from the cross Chuanmai 42xYr24/3*Avocet S and 726 F2 plants from Chuanmai 42xYr26/3*Avocet S were employed for allelic test of the resistance genes. In all, 819 pairs of wheat SSR primers were used to test the two parents, as well as resistant and susceptible bulks. Subsequently, nine polymorphic markers were employed for genotyping the F2 and F3 populations. Results indicated that the stripe rust resistance in Chuanmai 42 was conferred by a single dominant gene, temporarily designated YrCH42, located close to the centromere of chromosome 1B and flanked by nine SSR markers Xwmc626, Xgwm273, Xgwm11, Xgwm18, Xbarc137, Xbarc187, Xgwm498, Xbarc240 and Xwmc216. The resistance gene was closely linked to Xgwm498 and Xbarc187 with genetic distances of 1.6 and 2.3 cM, respectively. The seedling tests with 26 PST isolates and allelic tests indicated that YrCH42, Yr24 and Yr26 are likely to be the same gene.

Abstract
A novel flocculant based on hybrid Al(OH)(3)-polyacrylamide (HAPAM) has been synthesized using a redox initiation system ((NH(4))(2)S(2)O(8)-NaHSO(3)) at 40 degrees C in aqueous medium. The HAPAM was characterized by viscometry, IR spectroscopy, TEM, conductivity, and TGA. The flocculation behavior for 0.25 wt% kaolin suspension was evaluated by spectrophotometry and phase contrast microscopy. It was found that an ionic bond exists between Al(OH)(3) colloid and polyacrylamide (PAM) chains in the HAPAM and the flocculation efficiency of HAPAM is much better than that of commercial polyacrylamide (PAM) and PAM/AlCl(3) blend.

Abstract
A previous study has examined the performance of a fluidized activated carbon adsorber for removal of organics and particulate emissions from an incinerator under various fluidized operating conditions. The results show that it is an effective control device to treat the organics and coarse particles. However toxic heavy metal compounds cannot be completely destroyed during the incineration process and will volatilize at high temperature and then condense to form metallic particulates during the cooling of the flue gas. Therefore, continuing the previous study, the removal of metals generated from incineration by a fluidized bed adsorber at relatively low temperature was performed in the current study. Activated carbons with different additives (limestone, aluminum oxide and silica sand) were added in the adsorber to remove single metal (Pb, Cr and Cd) or mixed metals in the flue gas. Furthermore, an impulse bag house integrated after the adsorber and serving as an air pollution control device to control the metals and organics simultaneously was also identified. The results indicate that different additives can increase the removal efficiency of metals from 4% to 24% when the feedstock contains single metal. The integration of the fluidized bed adsorber and a bag house was effective to remove the heavy metals, organics and particulates in the flue gas.

Abstract
Giant cell reparative granuloma (GCRG) is an uncommon non-neoplastic lesion that typically occurs in the mandible and maxilla: however, its involvement with the temporal bone is rare. It is usually misdiagnosed as a giant cell tumor. Although regarded as a benign process, GCRG may be locally aggressive. In this paper, we describe two cases of GCRG of the temporal bone and review the pertinent literature published in English. The clinical course, histological evaluation, diagnosis, differential diagnosis, treatment and prognosis of GCRG of the temporal bone were investigated.

Abstract
Previous studies have shown that pollutants from incineration include heavy metals, organic compounds, particulate and acid gas. However, most studies on a single pollutant, it is rare for a study to concentrate on all possible pollutants and the relations between these pollutants under various incineration conditions. The objective of this work was to experimentally study the effect of different operating conditions on the pollutants emitted during incineration and the relations between these pollutants. The operating conditions of the experiments included the temperature of the combustion chamber and the species of organics. The findings indicated that the concentration of hydrogen chloride (HCl) in the presence of polyvinyl chloride (PVC) was higher than that of sodium chloride (NaCl). Regardless of what Cl-containing feedstock was added, the concentration of chromium (Cr) was constant. When organic chloride was added, Cr was the main metallic element which influenced the formation of polycyclic aromatic hydrocarbons (PAHs). On the other hand, when inorganic chloride (NaCl) was added, lead (Pb) was the major element.

Abstract
Modification of artemisinin structure led us to the discovery of a novel class of antitumor compounds. These artemisinin derivatives containing cyano and aryl groups showed potent antiproliferative effect in vitro against P388 and A549 cells. This activity was reflected in P388 murine leukemia by an accumulation of cells in G1 phase, and induction of apoptosis.

Abstract
Translational control by specific eIF2alpha phosphorylation on serine 51 has been characterized in all eukaryotes with the significant exception of plants. In order to evaluate the capability of plant eIF2alpha to functionally control translation, the wild type (51S) and a nonphosphorylatable mutant (51A) of wheat eIF2alpha were expressed in a yeast genetic system. Expression of either wheat protein did not handicap growth under conditions that repress the eIF2alpha phosphorylation pathway. However, under conditions that induce specific eIF2alpha phosphorylation only strains expressing wheat 51S were able to grow between 2 and 4 days. Growth was dependent upon activity of yeast eIF2alpha kinase GCN2 and resulted in the increased translation of GCN4. The association between plant eIF2alpha and yeast eIF2B is supported by their specific coimmunoprecipitation from transgenic yeast cells. These data support the similarity among eukaryotic translational initiation processes and strengthen the concept that plants may contain an eIF2alpha phosphorylation pathway.

Abstract
Phosphorylation of the alpha subunit of eukaryotic initiation factor 2 (eIF2alpha) is known to be an important translational control mechanism in all eukaryotes with the major exception of plants. Regulation of mammalian and yeast eIF2alpha activity is directly governed by specific phosphorylation on Ser-51. We now demonstrate that recombinant wheat wild-type (51S) but not mutant 51-Ala (51A) protein is phosphorylated by human PKR and yeast GCN2, which are defined eIF2alpha kinases. Further, only wheat wild-type eIF2alpha is a substrate for plant-encoded, double-stranded RNA-dependent kinase (pPKR) activity. Plant PKR and GCN2 phosphorylate recombinant yeast eIF2alpha 51S but not the 51A mutant demonstrating that pPKR has recognition site capability similar to established eIF2alpha kinases. A truncated version of wild-type wheat eIF2alpha containing 51S but not the KGYID motif is not phosphorylated by either hPKR or pPKR suggesting that this putative eIF2alpha kinase docking domain is essential for phosphorylation. Taken together, these results demonstrate the homology among eukaryotic eIF2alpha species and eIF2alpha kinases and support the presence of a plant eIF2alpha phosphorylation pathway.

Abstract
A DNA fragment containing the gene for D-hydantoinase was cloned from Pseudomonas putida CCRC 12857 into Escherichia coli. The cloned gene contained an open reading frame (ORF) of 1485 nucleotides encoding a protein of 53.4 kDa in which the carboxyl terminal end is longer than that previously deduced from strain DSM 84. This ORF was verified by amino acid sequencing of amino and carboxyl termini, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and amino acid sequence comparison. Deletion analysis revealed that 32 amino acids from the carboxyl terminal end were essential for D-hydantoinase activity. Tagging of six consecutive histidyl residues to the amino terminus or to the carboxyl terminus of the enzyme did not significantly affect D-hydantoinase activity. Under the control of T5lac promoter and lactose induction, the D-hydantoinase activity of transformed E. coli reached 200 U l-1 which is about 20-fold higher than that of gene donor strain.

Abstract
OBJECTIVE To determine the prevalence of diabetes and impaired glucose tolerance (IGT) and its risk factors in the Chinese population. RESEARCH DESIGN AND METHODS This study was a population-based cross-sectional study of 224,251 residents aged 25-64 years in 19 provinces and areas, including cities and rural areas of the north, south, east, and middle part of China. RESULTS Using the 1985 World Health Organization criteria, the prevalence of diabetes and IGT was 2.5 and 3.2%, respectively, in 213,515 subjects aged 25-64 years. Two thirds (70.3%) of the cases had newly recognized diabetes. The prevalence of diabetes in China is about three times higher than it was 10 years ago. On average, subjects with diabetes are older, have higher personal annual incomes, and more often have a family history of diabetes. They also have higher mean BMI, waist-to-hip ratio (WHR), systolic blood pressure, diastolic blood pressure, and a greater prevalence of hypertension. They perform less physical activity and have less education than people with normal oral glucose tolerance test results. Multiple logistic stepwise regression analysis shows that age, BMI (or WHR), family history of diabetes, hypertension, less physical activity, and higher annual income are independent risk factors of NIDDM, and that low education is also an independent risk factor of NIDDM in people with higher personal annual income. CONCLUSIONS The prevalence of diabetes in China is increasing with economic development and changes from traditional to modernized lifestyle, especially where people had lower level of education and socioeconomic development. Therefore, Chinese people should attempt to retain certain features of their traditional lifestyle (physical activity, healthy food, moderate body weight). Increased knowledge of risk factors for diabetes may help to prevent a further rapid increase in the prevalence of diabetes in China.

Abstract
The kinetics of drug release from fibrin adhesive agent (consisting of fibrinogen, factor 8, thrombin, aportinin and calcium chloride)-antibiotic compound and efficacy on rat experimental osteomyelitis were studied. To enhance the slow release activities of antibiotic, a mixture of fibrin clots was freeze-dried. Effects of freeze-drying were to make a fibrin clot an interlinked pore and to increase crosslinking rate containing an antibiotic. A diffusion test from aminoglycoside (Arbekacin Sulfate: 200 mg) compound was carried out. In vitro study freeze-dried antibiotic compound (FFAC: 1 cm3) was placed in saline (3 ml). The saline was replaced every 48 h and the previous solution was stored at -45 degrees C until assay. The result was that a concentration of 0.4 mg/l, sufficiently high to control Staphylococcus aureus strain IM2-42, was maintained within nine exchanges of saline after 18 days. In vivo animal experiments, FFAC (2 x 2 x 3 mm) were tested in rats with established Staphylococcus aureus osteomyelitis in the proximal tibia. The animals were observed for radiographic signs of infection and tissue was examined histopathologically. Bacterial counts by bone cultures were statistically lower in rats implanted with FFAC than in those only given a drug-free FFC and curettage. Radiographical and histological observations also showed beneficial effects of the FFAC. The results suggest that the FFAC provide a simple drug delivery system, and may be a promising alternative treatment for osteomyelitis.
