Abstract
Cell morphology is a fundamental feature used to evaluate patient specimens in pathologic analysis. However, traditional cytopathology analysis of patient effusion samples is limited by low tumor cell abundance coupled with the high background of nonmalignant cells, restricting the ability of downstream molecular and functional analyses to identify actionable therapeutic targets. We applied the Deepcell platform that combines microfluidic sorting, brightfield imaging, and real-time deep learning interpretations based on multidimensional morphology to enrich carcinoma cells from malignant effusions without cell staining or labels. Carcinoma cell enrichment was validated with whole genome sequencing and targeted mutation analysis, which showed a higher sensitivity for detection of tumor fractions and critical somatic variant mutations that were initially at low levels or undetectable in presort patient samples. Our study demonstrates the feasibility and added value of supplementing traditional morphology-based cytology with deep learning, multidimensional morphology analysis, and microfluidic sorting.

Abstract
Objective: To evaluate the efficacy of neoadjuvant chemotherapy (NACT) in the treatment of locally advanced olfactory neuroblastoma (ONB), and to explore the factors related to the efficacy of NACT. Methods: A total of 25 patients with ONB who underwent NACT in Beijing TongRen Hospital from April 2017 to July 2022 were retrospectively analyzed. There were 16 males and 9 females, with an average age of 44.9 years (ranged 26-72 years). There were 22 cases of Kadish stage C and 3 cases of stage D. After multiple disciplinary team(MDT) discussion, all patients were treated sequentially with NACT-surgery-radiotherapy. Among them, 17 cases were treated with taxol, cis-platinum and etoposide (TEP), 4 cases with taxol, nedaplatin and ifosfamide (TPI), 3 cases with TP, while 1 case with EP. SPSS 25.0 software was used for statistical analysis, and survival analyses were calculated based on the Kaplan-Meier method. Results: The overall response rate of NACT was 32% (8/25). Subsequently, 21 patients underwent extended endoscopic surgery and 4 patients underwent combined cranial-nasal approach. Three patients with stage D disease underwent cervical lymph node dissection. All patients received postoperative radiotherapy. The mean follow-up time was 44.2 months (ranged 6-67 months). The 5-year overall survival rate was 100.0%, and the 5-year disease-free survival rates was 94.4%. Before NACT, Ki-67 index was 60% (50%, 90%), while Ki-67 index was 20% (3%, 30%) after chemotherapy [M (Q1, Q3)]. The change of Ki-67 before and after NACT was statistically significant (Z=-24.24, P<0.05). The effects of age, gender, history of surgery, Hyams grade, Ki-67 index and chemotherapy regimen to NACT were analyzed. Ki-67 index≥25% and high Hyams grade were related to the efficacy of NACT (all P<0.05). Conclusions: NACT could reduce Ki-67 index in ONBs. High Ki-67 index and Hyams grade are clinical indicators sensitive to the efficacy of NACT. NACT-surgery-radiotherapy is effective for patients with locally advanced ONB.

Abstract
BACKGROUND Overweight and obesity in children and adolescents has become a worldwide epidemic. There are several studies that have concentrated on the prevalence rate of children and adolescents with intellectual disabilities (ID), whereas data on such a population on the mainland of China remain unclear. The purpose of this study was to investigate the prevalence rate of overweight and obesity among school-aged children and adolescents with ID on China's mainland. METHODS This study employed a cross-sectional design to examine the body weight status of 1873 children and adolescents (ages 6-18 years old) with ID in 35 special education schools. Body mass index was calculated, and the concepts of overweight and obesity were defined according to the standard of the Working Group for Obesity in China. RESULTS Data indicated that 18.2% (95% CI: 16.5%-20.0%) of children and adolescents with ID were overweight and 14.4% (95% CI: 12.8%-16.0%) were obese. Boys with ID were more likely to be overweight than girls with ID (OR = 1.48[95% CI: 1.13-1.94], P < 0.05). Children and adolescents with Down syndrome or autism spectrum disorder had a trend to be classified as overweight (OR = 1.76[95% CI: 1.22-2.54], P < 0.05; OR = 1.57[95% CI: 1.17-2.09], P < 0.05, respectively) or obesity (OR = 1.82[95% CI: 1.23-2.69], P < 0.05; OR = 1.40 [95% CI: 1.02-1.93], P < 0.05, respectively) compared with those with ID without these conditions. Moreover, children and teenagers with ID living in urban areas had a predisposition to be overweight (OR = 2.16[95% CI: 1.14-4.09], P < 0.05) or obese (OR = 3.25[95% CI: 1.41-7.50], P < 0.05) relative to those who lived in rural areas. CONCLUSION Results indicated that in China, the prevalence rate of overweight and obesity among school-aged children and adolescents with ID was remarkably high. Therefore, future research should make every effort to focus on reducing and preventing overweight and obesity of this population in China.

Abstract
OBJECTIVES The oldest old population has become the fastest growing segment with excess need of care and social support, it is crucial to improve the health-related quality of life (HRQoL) of these populations. This study seeks to evaluate the health status and to investigate modifiable factors associated with health-related quality of life for oldest old adults in China. DESIGN A cross-sectional population-based study. SETTING Hainan Province in the south of China. PARTICIPANTS 1,278 adults aged 80 years or older. METHODS HRQoL was assessed by three-level EuroQol-5D scale (EQ-5D-3L) and a visual analogue scale (VAS). Demographic and health-related variables were analysed by estimating mean values and standard deviations for continuous variables, percentages and standard deviations for categorical variables. Tobit regressions, ordinary least Squared (OLS) regressions and ordered probit regressions were adopted to determine the associated factors for overall HRQoL and for each health dimension. RESULTS Anxiety/depression was the least reported problem while mobility was the most frequently reported with problem. Female respondents had lower EQ-5D score (0.76 vs. 0.86) and VAS score (66.55 vs. 69.84) than male respondents. Better health-related quality of life was significantly associated with higher BMI, no drinking habit, more leisure activities, living with family members, good sleeping quality, closer social and family connections, fewer numbers of drugs consumed per day, without having hearing or visual impairment, and fewer chronic conditions, after controlling for potential confounders. CONCLUSION Findings from this study suggested that quality of life was not only associated with age-related diseases, but also correlated with a range of health-related lifestyles, and factors indicating social and family support.

Abstract
Objective: To describe the influence of post-operative anatomical structure changes on nasal airflow characteristics by 3D reconstruction and numerical simulation in real cases after nasalisation with Draf Ⅲ so as to explore the correlation between the changes of anatomical structure and subjective symptoms as well as airflow characteristics. Methods: Ten patients underwent nasalization with Draf Ⅲ in Department of Rhinology in Beijing Tongren Hospital from 2006 to 2018 were selected retrospectively. Postoperative follow-up of all patients was more than 1 year. All patients had no abnormalities in their paranasal sinus CT scans and Lund-Kennedy scores were 0 except scar. VAS scores including nasal obstruction, stimulation in frontal sinus, and headache were collected at the same period. The control model was a normal person. Numerical simulation was used for calculating airflow characteristics in deep inspiratory period of both models. Independent sample Mann-Whitney U test and Spearman correlation test were used by software SPSS 22.0. Results: The airflow pressure in frontal sinus ostium was (7.21±1.39)×10(4) Pa (Mean±SD), which was lower than that in normal subjects (8.99×10(4) Pa) under deep inspiratory simulation. But, the velocities in frontal sinus ostium and frontal sinus were (40.10±2.46) m/s and (28.19±1.73) m/s respectively, which were higher than those in normal one (2.70 m/s, 0.73 m/s). The airflow patterns of the two models were basically similar. There was no significant difference in the opening size and volume of frontal sinus between different groups after grouped by three symptoms respectively. No correlation could be found between the opening size and volume of the frontal sinus with the appearance and severity of three subjective symptoms. Conclusions: The airflow pattern and distribution after nasalisation with Draf Ⅲ are like those of normal person. There is no correlation between the changes of anatomy in frontal recess and frontal sinus and nasal airflow characteristics as well as subjective symptoms.

Abstract
Objective: To evaluate the cost-effectiveness of seasonal influenza vaccination, compared to no vaccination, for the elderly aged ≥60 years old in China. Methods: A static life-time Markov model is conducted to simulate the Chinese elderly population aged ≥60 years old. Taking the health care system perspective, one-year analytic cycle length is used for each influenza season. The model was assumed to be repeated until the individual reaches 100 years old. Three interventions were evaluated, including no vaccination, annual trivalent influenza vaccination, and annual quadrivalent influenza vaccination. Using the threshold of 3 times GDP per capita per Quality-adjusted life year (QALY) (193 932/QALY), the incremental cost-effectiveness ratio (ICER) was calculated to compare the cost-effectiveness of every two interventions.Model inputs like data for costs and utilities were from studies on Chinese population if they were available. QALY was used to measure health utility. One-way sensitivity analysis and probabilistic sensitivity analysis were adopted to quantify the level of confidence of the model output. Results: The total influenza associated costs of no vaccination would be 603 CNY per person, while the total costs of annual trivalent vaccination would be 1 027 CNY. Using trivalent vaccine would result in 0.007 QALY gained per person compared to no vaccination, with an increased cost of 424 CNY per person. The ICER of trivalent vaccination over no vaccination for all the elderly population in China would be 64 026 CNY per QALY gained, which was less than the threshold of 3 times GDP per capita. The total costs of annual quadrivalent vaccination would be 1 988 CNY. Using quadrivalent vaccine would result in 0.008 additional QALY gained per person compared to no vaccination, with an increased cost of 1 385 CNY per person. The ICER of quadrivalent vaccination over no vaccination would be 174 081 CNY per QALY gained, which was less than the threshold of 3 times GDP per capita. Conclusion: Vaccinating elderly population would improve health utilities at higher health care costs for the elderly. Using the threshold of 3 times GDP per capita per QALY (193 932/QALY), both trivalent and quadrivalent vaccination would be cost-effective compared to no vaccination in elderly Chinese population.

Abstract
Objective: To investigatea cellular/molecular mechanism of the CD40/TRAF1 signalling pathway involved in Rheumatoid arthritis (RA). Methods: 16 patients with active RA and 9 patients with Fractures who underwent total knee or hip replacement in The First Affiliated Hospital of Soochow University were included in the study. Synovial tissues (ST) and serum were obtained from each patient. The CD40, TRAF1, NF-κB p65 were detected by ELISA and Immunohistochemistry in serum and tissue respectively. Real time-PCR (RT-PCR) was applied to measure NF-κB-related gene expression. Results: CD40 and TRAF1 positive area (%) in RA patients were 28.7±5.4, 34.3±4.8 respectively, which were significantly higher (P<0.05) than Fracture controls (21.2±9.5, 21.6±8.7 respectively). The expression of total NF-κB p65, and phospho-NF-κB p65 proteins, as well as NF-κB-related gene expression, including cytokines (TNFα, IL-6), chemokines (MCP-1),and adhesion molecules (ICAM-1) were significantly higher in the ST of RA patients compared to Fracture controls. Conclusion: It is thus possible that the CD40/TRAF1 pathway acted as a positive regulator through NF-κB activation and NF-κB-dependent proinflammatory genes in RA.

Abstract
Preoperative radiation therapy has been regarded as the optional neoadjuvant treatment to decrease local recurrence of rectal cancer in addition to surgery. However, its benefit in survival remained obscure. This study was aimed to measure the efficacy of preoperative radiation therapy for survival in stage II and III rectal cancer patients. Retrospective cohort study used the database of Surveillance, Epidemiology and End Results program of the National Cancer Institute in the United States from 1988 to 2011. A total of 49439 patients diagnosed with primary rectal cancer who underwent surgery were included. Clinicopathological characteristics and rectal cancer-specific survival between surgery alone group and surgery plus preoperative radiation therapy group were compared. Rectal cancer patients in surgery plus preoperative radiation therapy group had significantly better survival than those in surgery alone group (72.70% vs. 66.61%, P < 0.001), as well as stratified by stages (stage II: 77.4% vs. 74.3%, P < 0.001; stage III: 68.3% vs. 58.6%, P < 0.001). However, this beneficial impact was only observed after 2000s (P < 0.001). Multivariate survival analysis revealed that preoperative radiation therapy was an independent predictor for better survival in stage III (hazard ratio, 0.795; 95% CI, 0.753-0.840; P < 0.001), but not in stage II (P = 0.70). Preoperative radiation therapy might bring a better survival in stage II and III rectal cancer patients, but only as an independent predictor for stage III patients. As time progressed, preoperative radiation therapy might yield more profit for stage II and III rectal cancer patients.

Abstract
Objective: To investigate the prevalence of high-risk HPV subtypes in different pathological types of cervical cancer, and analyze the attribution of carcinogenic HPV subtypes in different pathological types. Methods: A total of 1 541 patients with cervical cancer were treated between February 2009 and October 2016 in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. The median age at diagnosis was 49 years (ranged 20-82 years old). The numbers of patients with cervical cancer from North China, Northeast China, East China, Central China and other regions (including Northwest, Southwest and South China) were 961, 244, 175, 87 and 74 cases, respectively. Pathological types: 1 337 cases of squamous cell carcinoma (SCC), 87 usual adenocarcinoma (ADC), 23 adenosquamous carcinoma (ASC), 20 mucinous carcinoma (MC), 19 clear cell carcinoma (CCC), 12 endometrioid carcinoma (EC), 25 neuroendocrine carcinoma (NEC), 9 serous carcinoma (SC), 5 villous adenocarcinoma (VADC) and 4 minimal deviation adenocarcinoma (MDAC). The prevalence of high-risk HPV in different regions, age groups at diagnosis and pathological types in cervical cancer were analyzed. The attribution of 13 high-risk HPV subtypes in different pathological types of cervical cancer based on proportional attribution method, and the attribution of high-risk HPV subtypes prevented by 9-valent HPV vaccine in SCC and ADC were calculated. Results: (1) The prevalence of high-risk HPV in 1 541 patients with cervical cancer was 86.6% (1 335/1 541). The multiple high-risk HPV infection rate in patients with SCC ≥60 years old (23.0%, 37/161) was significantly higher than those in patients aged 45-59 years old and ≤44 years old [11.4% (85/747) vs 11.7% (50/429), P<0.01], and the high-risk HPV infection rates of patients with cervical cancer in North China, Northeast China, East China, Central China and other regions were respectively 86.8% (834/961), 87.7% (214/244), 83.4% (146/175), 83.9% (73/87) and 91.9% (68/74). SCC (86.8%, 1 337/1 541) and ADC (5.6%, 87/1 541) were the most common pathological types in cervical cancer. The high-risk HPV prevalence of SCC, ADC, ASC, MC, NEC and VADC were 90.1% (1 205/1 337), 74.7% (65/87), 87.0% (20/23), 65.0% (13/20), 72.0% (18/25) and 5/5 respectively. The high-risk HPV infection rates of SC, EC, CCC and MDAC were 4/9, 3/12, 2/19 and 0/4 respectively. (2) According to proportional attribution, HPV 16 (69.5%), HPV 18 (5.6%), HPV 58 (2.2%), HPV 31 (1.9%), HPV 52 (1.4%) and HPV 33 (1.3%) were the six common high-risk HPV subtypes in SCC. While, HPV 18 (44.1%), HPV 16 (20.5%), HPV 52 (2.3%), HPV 58 (1.2%) and HPV 51 (1.2%) were the main carcinogenic subtypes in ADC. The main carcinogenic high-risk HPV subtypes of ASC, NEC and MC were HPV 18 and HPV 16. The total attribution of HPV 16, 18, 31, 33, 45, 52 and 58 prevented by 9-valent HPV vaccine in SCC and ADC were 82.6% and 68.1% respectively; the attribution of HPV 45 in SCC and ADC were only 0.8% and 0. Conclusions: SCC and ADC are the main pathological types in cervical cancer. SCC, ADC, ASC, MC, NEC and VADC are closely related to high-risk HPV infection. HPV 16 is the main carcinogenic genotypes of SCC. HPV 18 maybe play an important role in the pathogenesis of ADC.

Abstract
Objective: To investigate the protective effect of liraglutide on kidney of diabetic mice induced by high-fat diet and its possible mechanisms. Methods: C57BL/6J male mice were randomly divided into normal chow diet (NC) group and high-fat diet (HFD) group, which were fed with normal chow diet and HFD for 12 weeks respectively. After diet challenge, the mice were randomly divided into normal control group, normal chow diet with liraglutide treatment (NC+Lira) group, HFD group and high-fat diet with liraglutide treatment (HFD+Lira) group. The mice in NC+Lira and HFD+Lira groups were given intraperitoneal injection of liraglutide (400 μg·kg(-1)·d(-1)) for 8 weeks, while mice in NC and HFD groups were given intraperitoneal injection of same amount of normal saline. Urinary albumin and creatinine levels were measured by enzyme-linked immunosorbent assay (ELISA). Renal morphology was observed by HE staining. The expression levels of silent mating type information regulation 2 homolog 1 (SIRT1) and thioredoxin-interacting protein (TXNIP) were determined by Western blot. Results: Compared with HFD group, liraglutide significantly lowered the body weight [(30.98±1.29) g vs (39.43±2.58) g], fasting blood glucose (FBG) [(7.21±0.15) mmol/L vs (9.55±0.29) mmol/L] and urinary albumin/creatinine ratio (ACR) [(205.48±17.14) μg/mg vs (319.86±34.14) μg/mg] in HFD+Lira group (all P<0.05). HE staining showed that glomerular hypertrophy of HFD group alleviated after liraglutide treatment. The expression level of TXNIP in the kidney of HFD mice significantly decreased after liraglutide treatment (0.41±0.10 vs 3.50±0.70), while expression level of SIRT1 significantly increased (0.75±0.15 vs 0.32±0.04) (both P<0.05). Conclusion: Liraglutide could improve diabetic nephropathy by up-regulation of SIRT1 expression and down-regulation of TXNIP expression in diabetic mice induced by HFD.

Abstract
Objectives: To discuss the clinical and radiological features of IgG4-related rhinosinusitis. Methods: In this retrospective research, the clinical data of 16 patients diagnosed with IgG4 related rhinosinusitis, who were enrolled in Beijing Tongren Hospital from November 2013 to September 2017, were collected. The clinical features, laboratory findings, radiological findings, histological features, treatment and prognosis were all summarized. Results: There were 12 males and 4 females among 16 patients, and male-to-female ratio was 3︰1. The age was between 30 to 70 years old, with median age of 52 years old. The chief nasal complaints were nasal obstruction and hyposmia, complicated with proptosis and eyelid swelling in 11 patients (11/16). Serum IgG4 levels were elevated in all patients and the value was over 1.44 g/L, and one patient serum IgG4 level was up to 49.70 g/L. Computed tomography (CT) showed the mainly affected sinuses were bilateral ethmoid sinus and olfactory cleft. The classic feature of CT scans was thickening of the involved bilateral ethmoid sinus mucous membrane with ethmoid bone absorption, which was mainly at midline. Histological features were severe inflammation of the mucosal tissue with mass of neutrophils and plasma cell infiltration. All patients were treated by methylprednisolone combined with cyclophosphamide or methotrexate. Remission of symptoms was detected in all patients. Conclusion: The clinical features of IgG4-related rhinosinusitis are often accompanied by orbital tissue involvement, elevated IgG4 serum concentration, associated sinus imaging changes, and sensitive glucocorticoid and immunosuppressive therapy.

Abstract
To analyze the correlation between transcutaneous oxygen pressure (P(tc)O(2)) and blood lactate in patients with septic shock. Fifty-sixpatients with septic shock were prospectively investigated. P(tc)O(2) was monitored continuously for 6 hours, and arterial blood gas was measured at baseline (T0) and 6 hours(T6). Records of P(tc)O(2),were analyzed for the correlation with lactate level and lactate clearance rate. P(tc)O(2) valuesin the high lactate clearance group and the low one were compared.The lowest value of P(tc)O(2) at T6 and duration of P(tc)O(2)<40 mmHg (1 mmHg=0.133 kPa) were both correlated with lactate level and lactate clearance rateat T6.The low predictive value of P(tc)O(2) was 29 mmHg of lactate clearance under 20% with a sensitivity 85.2% and a specificity 65.5%. The low predictive value of P(tc)O(2) in high lactate clearance group was significantly higher than that in low lactate clearance group, while the duration of P(tc)O(2)<40 mmHg was shorter than the latter. During 6 h continuous monitoring, patients with a significant low P(tc)O(2) or prolonged duration of low P(tc)O(2) have relatively high lactate or low lactate clearance after resuscitation.

Abstract
Objective: To explore the effects of N-(4-hydroxyphenyl) retinamide (4HPR), 4HPR liposome (4HPR-L), and 4HPR lipid microbubble (4HPR-LM) combined with ultrasound on proliferation, apoptosis, and cell cycle of human keloid fibroblasts (Fbs). Methods: (1) 4HPR-L and 4HPR-LM were prepared by hydration ultrasonic method. The appearance morphology, particle size distribution, Zeta potential, loading drug concentration, encapsulation efficiency, and drug loading rate of 4HPR-L were investigated by high performance liquid chromatography, dynamic light scattering, and transmission electron microscope. (2) Human keloid Fbs were cultured and divided into 13 groups by random number table (the same grouping method below), with 6 wells in each group. Cells in control group were given no treatment, while cells in 12 ultrasound groups including 0.5 W 30 s group, 0.5 W 60 s group, 0.5 W 120 s group, 0.7 W 30 s group, 0.7 W 60 s group, 0.7 W 120 s group, 1.0 W 30 s group, 1.0 W 60 s group, 1.0 W 120 s group, 1.5 W 30 s group, 1.5 W 60 s group, and 1.5 W 120 s group were treated by ultrasound with corresponding parameters. The cells viability was measured by a microplate reader after 24 hours of routine culture. Another batch of human keloid Fbs were divided into 5 groups, with 6 wells in each group. Cells in control group were given no treatment, while cells in 1, 10, 20, and 50 μg/mL blank lipid microbubble groups were treated with blank lipid microbubbles in corresponding mass concentration. The cells viability was measured as before after 24 hours of routine culture. Another batch of human keloid Fbs were divided into 6 groups, with 12 wells in each group. Cells in control group were given no treatment, while cells in 1, 10, 20, 50, and 100 μg/mL 4HPR-L groups were added with 4HPR-L carrying corresponding mass concentration of 4HPR. The cells viability in 6 wells of each group was detected after 24 and 48 hours of routine culture, respectively. Another batch of human keloid Fbs were divided into 4 groups, with 6 wells in each group. Cells in control group were given no treatment, while cells in 4HPR, 4HPR-L, and 4HPR-LM+ ultrasound groups were treated with 4HPR, 4HPR-L, and 4HPR-LM (all the mass concentration of 4HPR was 20 μg/mL), respectively, and cells in 4HPR-LM+ ultrasound group were given 0.5 W 60 s ultrasound treatment immediately after drug administration. The cells viability was measured as before after 24 hours of routine culture. (3) Another batch of human keloid Fbs were divided into control group, 4HPR group, 4HPR-L group and 4HPR-LM+ ultrasound group, with 3 wells in each group, and the cells in each group were treated as before. Apoptosis of the cells was detected by flow cytometer after 24 hours of routine culture. (4) Another batch of human keloid Fbs were grouped and treated as in (3), and then the cell cycle distribution was detected by flow cytometer after 24 hours of routine culture. Data were processed with one-way analysis of variance and t test. Results: (1) 4HPR-L particles had a spherical or spheroidal structure and were uniform in size, with particle size of (100.1±1.3) nm and Zeta potential of (-34.3±2.3) mV. The mass concentration of 4HPR in 4HPR-L solution was about 1 400 μg/mL, with the encapsulation efficiency of (95.8±1.2)% and drug loading rate of (8.3±0.4)%. (2) The viability of cells in the 12 ultrasound groups was higher than 93.0%, and the viability of cells in 1, 10, 20, and 50 μg/mL blank lipid microbubble groups was higher than 95.0%. The viability of cells in 1 μg/mL 4HPR-L group at administration hour 24 was similar to that at 48 (t=0.393, P>0.05). The viability of cells in 10, 20, 50, and 100 μg/mL 4HPR-L groups at administration hour 24 was significantly higher than that at administration hour 48 (t=44.593, 22.961, 32.224, 35.337, P<0.01). The viability of cells in 4HPR group, 4HPR-L group, and 4HPR-LM+ ultrasound group was (47.3±0.7)%, (42.3±1.7)%, and (38.6±0.8)%, respectively. The viability of cells in 4HPR group was significantly higher than that in 4HPR-L group and 4HPR-LM+ ultrasound group (t=4.551, 15.895, P<0.05 or P<0.01). The viability of cells in 4HPR-L group was significantly higher than that in 4HPR-LM+ ultrasound group (t=-3.360, P<0.05). (3) The percentages of total apoptotic cells in 4HPR group, 4HPR-L group, and 4HPR-LM+ ultrasound group were (32.8±2.4)%, (42.5±2.4)%, and (58.5±6.3)%, respectively, which were significantly higher than the percentage of control group [(14.9±1.6)%, t=8.748, 13.637, 9.500, P<0.01]. The percentages of total apoptotic cells in 4HPR-L group and 4HPR-LM+ ultrasound group were significantly higher than the percentage in 4HPR group (t=4.049, 5.393, P<0.05 or P<0.01), and the percentage of total apoptotic cells in 4HPR-LM+ ultrasound group was significantly higher than that in 4HPR-L group (t=3.371, P<0.01). (4) The percentage of G2/M phase cells in 4HPR group was higher than that in control group, but there was no statistically significant difference (t=2.107, P>0.05). The percentage of G2/M phase cells in 4HPR-L group was significantly higher than that in 4HPR group or control group (t=18.169, 30.026, P<0.01). The percentage of G2/M phase cells in 4HPR-LM+ ultrasound group was significantly higher than that in 4HPR-L group, 4HPR group, and control group (t=4.932, 25.854, 66.231, P<0.01). Conclusions: 4HPR can inhibit proliferation, induce apoptosis, and arrest G2/M phase of human keloid Fbs, and the effects of 4HPR-LM combined with ultrasound are better than those of 4HPR-L and free 4HPR.

Abstract
Objective:To study the surgical outcomes of functional endoscopic sinus surgery and radical sinus surgery for refractory rhinosinusitis.Method:A retrospective analysis of 56 cases with refractory rhinosinusitis was performed, who were enrolled in Beijing Tongren hospital from January 2011 to April 2013. According to different surgical methods, all patients were classified into functional endoscopic surgery group (FESS group) and radical sinus surgery group (RSS group). All patients were followed up for more than one year after surgery. Symptom visual analog scale (VAS), peripheral blood eosinophil percentage, serum total IgE, skin prick test (SPT), olfactory function, Lund-Kennedy score and Lund-Mackay score were all examined and analyzed in two groups before and after surgery. SPSS 17.0 was used to do data statistic analysis.Result:There was no significant difference between two groups in age, gender, complicated with allergic rhinitis and asthma (P> 0.05). However, there was significant difference between two groups in the number of patients with previous surgery (P< 0.05). Pre-operative VAS symptom score, Lund-Kennedy score and Lund-Mackay score were higher in RSS group than in FESS group. All patients were followed up for at least one year. VAS symptom score, Lund-Kennedy score and Lund-Mackay score in two groups were compared before and after surgery respectively. VAS symptom score (P< 0.01; P< 0.01), Lund-Kennedy score (P< 0.01; P< 0.01), Lund-Mackay score (P< 0.01; P< 0.01) were significantly lower after surgery. There was no significant difference in VAS symptom scores between two groups postoperatively (P> 0.05). However, Lund-Kennedy score (P< 0.01) and Lund-Mackay score (P< 0.01) were lower in RSS group postoperatively. Among patients with surgery history, Lund-Kennedy score (P< 0.01) and Lund-Mackay score (P< 0.01) were also lower in RSS group at one year follow-up. Conclusion:Radical sinus surgery was more effective in relieving symptoms and reducing inflammation of sinus, compared with functional sinus surgery, especially in refractory sinusitis patients with previous surgery.

Abstract
Objective: To investigate the therapeutic effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with FLAG sequential busulfan/cyclophosphamide(Bu/Cy) conditioning regimen for refractory/relapsed acute myeloid leukemia. Methods: From February 2012 to June 2017, 21 patients with refractory/relapsed acute myeloid leukemia underwent allo-HSCT with FLAG sequential Bu/Cy conditioning regimen. Transplantation-related complications and clinical outcome were retrospectively analyzed. Results: After conditioning, no hepatic veno-occlusive disease (VOD) and grade Ⅲ hemorrhagic cystitis occurred. 76.2% (16/21) patients had fever with 4 septicemia. One patient died of septic shock before engraftment. Twenty patients achieved neutrophil engraftment with a median time of 13 days (range, 10 to 21 days). Seventeen patients achieved platelet engraftment with a median time of 18 days (range, 9 to 25 days). The cumulative incidence of acute graft-versus-host disease (aGVHD) was 39.5%, and 3 patients developed grade Ⅲ-Ⅳ aGVHD. Of 19 patients who survived more than 100 days after transplantation, 4 had local chronic graft-versus-host disease (cGVHD). Of 21 patients, the median survival time was 15 months (range, 0.5 to 67 months) post-transplantation. Transplantation-related mortality rate was 28.7%. Leukemia relapse occurred in 4 patients with a median time of 4 months (range, 3 to 8 months) after transplantation. The cumulative relapse rate at 1 year was 21.4%. The 1-year and 3-year overall survival (OS) rates were 60.7% and 54.9% respectively. Log-rank analysis revealed that bone marrow blasts ≥ 20% or extramedullary leukemia before transplantation, poor platelet engraftment and grade Ⅲ-Ⅳ aGVHD were significantly related to shortened OS (P<0.05). Conclusions: Allo-HSCT with FLAG sequential Bu/Cy conditioning regimen in patients with refractory/relapsed myeloid leukemia has acceptable transplantation-related risk and relapse rate. The 1-year and 3-year OS rates are comparable with those in remission patients.

Abstract
Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound, the examiner and interpreter of the image are critical care medicine physicians. The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes. With the idea of critical care medicine as the soul, it can integrate the above information and clinical information, bedside real-time diagnosis and titration treatment, and evaluate the therapeutic effect so as to improve the outcome. CUS is a traditional technique which is applied as a new application method. The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept, implementation and application of CUS. It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure. At the same time, the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications, and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS. Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group, based on the rich experience of clinical practice in critical care and research, combined with the essence of CUS, to learn the traditional ultrasonic essence, established the clinical application technical specifications of CUS, including in five parts: basic view and relevant indicators to obtain in CUS; basic norms for viscera organ assessment and special assessment; standardized processes and systematic inspection programs; examples of CUS applications; CUS training and the application of qualification certification. The establishment of applied technology standard is helpful for standardized training and clinical correct implementation. It is helpful for clinical evaluation and correct guidance treatment, and is also helpful for quality control and continuous improvement of CUS application.

Abstract
Objective:The aim of this study is to investigate the clinical features of different subtypes of fungal ball sinusitis. Method:Four hundred and forty-nine cases with fungal ball rhinosinusitis (FBS) were involved in this retrospective analysis. The clinical features including symptoms, signs, and imaging scans, pathological results were all collected for each patient and the patients were classified into different subtypes according to these clinical features and the follow-up treatment. Result:In this retrospective study, 449 patients who diagnosed with fungal ball sinusitis were involved. According to clinical features, these patients were divided into 5 subtypes respectively: ①Subtype 1 simple FBS: there were 299 patients in this subtype. Main symptoms were one side headache, purulent rhinorrhea, nasal obstruction. CT scans showed the classical features of FBS. ②Subtype 2 FBS with nasal polyps: there were 78 patients in this subtype. Main symptoms were bilateral or unilateral nasal obstruction, purulent rhinorrhea. Histopathologic results showed nasal polyps with acute or chronic inflammation by inflammatory cell infiltration. Eosinophils infiltration was the most common phenomenon. Postoperative therapy was as same as the treatment to chronic rhinosinusitis. ③Subtype 3 FBS with allergic rhinitis:there were 51 patients in this subtype. During the operation, infected nasal sinus mucosa with serious edema could be found, often with asubmucosa cyst. Postoperative medical therapy with antihistamines during follow-up. ④Subtype 4 FBS with purulent cyst: there were 6 cases. Main symptoms were nasal obstruction, purulent rhinorrhea and facial pain. Sinus CT scans showed that the typical features of both fungal ball sinusitis and mucous cyst. Antibiotic saline nasal irrigation should be used intraoperatively and postoperatively, other than systemic antibiotic treatment. ⑤Subtype 5 mixed type: there were 15 cases. All of these patients were diagnosed with fungal ball sinusitis with nasal polyps combined with allergic rhinitis. The clinical features of diagnosis and treatment were combination of the two types. Conclusion:According to the different clinical features, fungal ball sinusitis could be classified with five different clinical features. This classification would help to standardize the treatment, reduce the postoperative recurrence rate, and improve the prognosis.

Abstract
OBJECTIVE To investigate the prognostic significance of venous-to-arterial carbon dioxide difference to arteriovenous oxygen content difference ratio (Pv-aCO2/Ca-vO2 ratio) combined with lactate in patients with septic shock during the early phases of resuscitation. METHODS A retrospective study was conducted for 104 septic shock patients. All patients received an initial fluid resuscitation according to the Surviving Sepsis Campaign: International Guidelines for Management of Severe Sepsis and Septic Shock, 2012(SSC2012). Patients were classified into four groups according to lactate levels and Pv-aCO2/Ca-vO2 ratio at 6 h of resuscitation: group A, lactate≥2.0 mmol/L and Pv-aCO2/Ca-vO2>1.0; group B, lactate≥2.0 mmol/L and Pv-aCO2/Ca-vO2≤1.0; group C, lactate<2.0 mmol/L and Pv-aCO2/Ca-vO2>1.0; group D, lactate<2.0 mmol/L and Pv-aCO2/Ca-vO2≤1.0. The hemodynamic parameters and oxygen metabolism parameters were recorded at baseline and 6 h after fluid resuscitation. Sequential organ failure assessment (SOFA) score at day 1, day 3 were calculated. The 28-day mortality rate was recorded. RESULTS (1) Group A had the highest SOFA score at day 3 and group D the lowest, which were respectively 10.8±3.3, 6.7±3.6, 5.6±3.1, 4.1±2.2 in four groups. Accordingly, the 28-day mortality rate of group A was the highest and group D the lowest, which were respectively 83.3%, 59.1%, 60.0%, 14.3% in four groups. The differences were statistically significant (P<0.05). (2) The Cox regression analysis of 28 d mortality revealed that lactate levels (RR=4.306, 95%CI 1.979-9.369) and Pv-aCO2/Ca-vO2 ratio (RR=2.888, 95%CI 1.676-4.976) at T6 were independent predictors to 28-day mortality. (3) The AUCROC of Pv-aCO2/Ca-vO2 ratio combined with lactate [0.910(95%CI 0.857-0.963)] was significantly greater than the AUCROC of wither lactate [0.762(95%CI 0.673-0.852), Z=2.775; P=0.006) or Pv-aCO2/Ca-vO2 ratio [0.781(95%CI 0.693-0.868), Z=2.458; P=0.014) alone. CONCLUSION Combination of Pv-aCO2/Ca-vO2 ratio and lactate level at early stage of resuscitation in patients with septic shock is better than single parameter to predict the prognosis.

Abstract
OBJECTIVES To investigate the clinical predictors and the aetiologies for surgery in patients with Naja atra (Taiwan or Chinese cobra) envenomation. METHODS This case series was conducted in the only tertiary care centre in eastern Taiwan. Patients who presented to the emergency department with Naja atra bite between January 2008 and September 2014 were included. Clinical information was collected and compared between surgical and non-surgical patients. RESULTS A total of 28 patients with Naja atra envenomation presented to the emergency department during the study period. Of these, 60.7% (n=17) required surgery. Necrotising fasciitis (76.5%) was the main finding in surgery. Comparisons between surgical and non-surgical patients showed skin ecchymosis (odds ratio=34.36; 95% confidence interval, 2.20-536.08; P=0.012) and a high total dose of antivenin (≥6 vials; odds ratio=14.59; 95% confidence interval, 1.10-192.72; P=0.042) to be the most significant predictors of surgery. The rate of bacterial isolation from the surgical wound was 88.2%. Morganella morganii (76.5%), Enterococcus faecalis (58.8%), and Bacteroides fragilis (29.4%) were the most common pathogens involved. Bacterial susceptibility testing indicated that combined broad-spectrum antibiotics were needed to cover mixed aerobic and anaerobic bacterial infection. CONCLUSIONS Patients with Naja atra envenomation who present with skin ecchymosis or the need for a high dose of antivenin may require early surgical assessment. Combined broad-spectrum antibiotics are mandatory.

Abstract
The aim of this study was to examine the association between polymorphisms in the interleukin-3 and -13 (IL-3 and IL-13) genes and rheumatoid arthritis (RA). In this hospital-based case-control study, we analyzed the IL-3 rs2073506 G/A, IL-3 rs40401 C/T, and IL-13 rs1800925 C/T polymorphisms in 615 RA patients and 839 controls from a Chinese Han population. Genotyping was performed using a custom-by-design 48-Plex single nucleotide polymorphism scanTM kit. Our results indicated that the IL-3 rs2073506 G/A, IL-3 rs40401 C/T, and IL-13 rs1800925 C/T polymorphisms were not associated with RA. However, stratification analyses suggested that the IL-13 rs1800925 CT and CT/CC genotypes increased the risk of RA in patients with erythrocyte sedimentation rate (ESR) <25.00. To sum up, these findings suggest that the IL-13 rs1800925 C/T polymorphism may be associated with increased risk of RA in ESR <25.00 patients. Future studies with larger sample sizes and inclusion of other ethnic populations must be conducted to confirm the findings of this study.

Abstract
BACKGROUND Workplace noise exposure gains growing attention in high tech industry. OBJECTIVE This study investigated the noise effect on physiological and subjective responses in semiconductor manufacturing clean room environment. METHODS Twenty subjects including 10 males and 10 females completed all phases of the experiment. Each subject was asked to participate in four treatment combinations of two noise intensities [65 dB(A) and 80 dB(A)] × two frequency levels [high and low]. For each treatment condition, the subject was exposed to the specified noise condition in a sound proof cabin for one hour. The physiological measures included blood pressure and heart rate. The subjective measures included noise sensitivity, fatigue and annoyance. RESULTS The ANOVA results indicate that long-time noise exposure caused significant increase in blood pressure (p< 0.001). Furthermore, the noise intensity by time interaction effect was found to be significant on annoyance and fatigue. CONCLUSIONS The findings suggest that prolonged exposure to noise intensity at 80 dB(A) would result in a significant increase in physiological cost and subjective discomfort feeling. Thus, some countermeasures should be taken to reduce noise exposure and to promote health, and quality of working life.

Abstract
OBJECTIVE To evaluate the radiographic outcomes of short-segment posterior instrumentation plus vertebroplasty using injectable calcium sulfate cement (CSC) for thoracolumbar compression fractures. MATERIALS AND METHODS Twenty-eight patients with a single-level thoracolumbar compression fracture, who underwent short-segment pedicle screw fixation and CSC vertebroplasty, were included in the study. The anterior vertebral body height ratio, local kyphosis angle, and the height of the intervertebral disc adjacent to the fractured vertebra were used to evaluate the radiographic results. Complications including bone nonunion, instrument failure, cement leakage, and disc vacuum formation were also assessed. RESULTS The patients were followed up for an average of 24.20±5.40 months. The relative preoperative anterior body height was 55.71±15.29%, which improved to 94.93±5.39% immediately after surgery (P<0.001), and at final follow-up showed a 6.50±3.89% loss of height correction (P<0.001). The mean preoperative local kyphosis angle was 22.23±5.65°, which corrected to 2.67±4.43° immediately after surgery (P<0.001), but reverted to 6.71±4.95° at final follow-up, showing a 4.04±1.91° loss of correction (P<0.001). The mean height of the intervertebral disc proximal to the fractured vertebra was 9.87±0.91 mm before surgery, 12.53±0.98 mm after operation (P<0.001), and the loss of correction at final follow-up was 2.35±1.15 mm with a significant difference compared to immediate postoperative values (P<0.001). Bone nonunion occurred in 7 patients, 2 patients had hardware failure, 9 patients had cement leakage, and 10 patients had disc vacuum phenomenon adjacent to the fractured vertebra. CONCLUSIONS The patients who underwent this procedure had a loss of correction of vertebral height and local kyphosis. Complications such as bone nonunion, instrument failure, cement leakage, and disc vacuum may occur. Rapid CSC resorption accounts for these radiographic outcomes and complications. LEVEL OF EVIDENCE Level IV, retrospective study.

Abstract
We have constructed a scanning probe microscope for magnetic imaging, which can function as a scanning Hall probe microscope (SHPM) and as a scanning SQUID microscope (SSM). The scanning scheme, applicable to SHPM and SSM, consists of a mechanical positioning (sub) micron-XY stage and a flexible direct contact to the sample without a feedback control system for the Z-axis. With the interchangeable capability of operating two distinct scanning modes, our microscope can incorporate the advantageous functionalities of the SHPM and SSM with large scan range up to millimeter, high spatial resolution (⩽4 μm), and high field sensitivity in a wide range of temperature (4.2 K-300 K) and magnetic field (10(-7) T-1 T). To demonstrate the capabilities of the system, we present magnetic images scanned with SHPM and SSM, including a RbFeB magnet and a nickel grid pattern at room temperature, surface magnetic domain structures of a La(2/3)Ca(1/3)MnO3 thin film at 77 K, and superconducting vortices in a striped niobium film at 4.2 K.

Abstract
This study examined different methodologies to modify activated carbon (AC) for the removal of quaternary amine, tetramethylammonium hydroxide (TMAH), from water. Commercial carbon (WAC) was treated by nitric acid oxidation (NA-WAC), silica impregnation (SM-WAC0.5), and oxygen plasma (P10-WAC), and their characteristics and adsorption capacity were compared. The Langmuir model fitted the equilibrium adsorption data well under different pH. The maximum adsorption capacity of WAC was 27.77 mg/g, while those of NA-WAC, SM-WAC 0.5, and P10-WAC were 37.46, 32.83 and 29.03 mg/g, respectively. Nitric acid oxidation was the most effective method for enhancing the adsorption capacity of TMAH. Higher pH was favorable for TMAH adsorption. Desorption study revealed that NA-WAC had no considerable reduction in performance even after five cycles of regeneration by 0.1 N hydrochloric acid. It was proposed that electrostatic interaction was the main mechanism of TMAH adsorption on activated carbon.

Abstract
Wheat-Dasypyrum villosum translocated chromosomes T6V#2S•6AL and T6V#4S•6DL are known to confer excellent resistance to wheat powdery mildew (PM). However, it is difficult to distinguish the two sources of PM resistance genes through multi-pathotype testing because to date no virulence for them has been found. To reveal the relationship between the PM resistance genes from the two translocations, the sequence of the Stpk-V gene, a key member of powdery mildew resistance locus Pm21, was used as a reference to isolate homologous genes from a D. villosum accession No.1026 and its derivatives 6V#4(6D) disomic substitution (DS) line RW15 and T6V#4S•6DL translocation line Pm97033. Two genes Stpk-V2 and Stpk-V3 were cloned from No.1026. Sequence alignment showed that Stpk-V2 and Stpk-V3 shared 98.2 % and 96.2 % of their DNA and 99.3 % and 100 % of their amino acids in identity with Stpk-V. Compared with Stpk-V, a 22-bp direct sequence repeat and a miniature inverted-repeat transposable element (MITE) were found in the intron 4 of Stpk-V2 and Stpk-V3, respectively. However, Stpk-V2 was not present in DS line RW15 and translocation line Pm97033 based on the PCR result, indicating that Stpk-V2 did not contribute to the PM resistance of RW15 and Pm97033. In the promoter region, a 78-bp insertion was found not only in Stpk-V2 and Stpk-V3, but also in its orthologous gene Stpk-A of wheat. In addition, there was a 17 bp/8 bp deletion/insertion in the putative promoter of Stpk-V3 in comparison with that of Stpk-V/Stpk-V2. Real-time quantitative RT-PCR analysis indicated that the expression levels of Stpk-V and Stpk-V3 genes in the translocation lines were induced by the pathogen, but Stpk-V had a higher expression level than Stpk-V3 at 12 h after inoculation with Bgt. The diversity of Stpk-V gene will help to explore new resistance genes to PM in D. villosum for wheat breeding.

Abstract
An in vitro fermentation was conducted to determine the effects of hainanmycin on protein degradation and populations of ammonia-producing bacteria. The substrates (DM basis) for in vitro fermentation consisted of alfalfa hay (31.7%), Chinese wild rye grass hay (28.3%), ground corn grain (24.5%), soybean meal (15.5%) with a forage: concentrate of 60:40. Treatments were the control (no additive) and hainanmycin supplemented at 0.1 (H0.1), 1 (H1), 10 (H10), and 100 mg/kg (H100) of the substrates. After 24 h of fermentation, the highest addition level of hainanmycin decreased total VFA concentration and increased the final pH. The high addition level of hainanmycin (H1, H10, and H100) reduced (p<0.05) branched-chain VFA concentration, the molar proportion of acetate and butyrate, and ratio of acetate to propionate; and increased the molar proportion of propionate, except that for H1 the in molar proportion of acetate and isobutyrate was not changed (p>0.05). After 24 h of fermentation, H10 and H100 increased (p<0.05) concentrations of peptide nitrogen and AA nitrogen and proteinase activity, and decreased (p<0.05) NH3-N concentration and deaminase activity compared with control. Peptidase activitives were not affected by hainanmycin. Hainanmycin supplementation only inhibited the growth of Butyrivibrio fibrisolvens, which is one of the species of low deaminative activity. Hainanmycin supplementation also decreased (p<0.05) relative population sizes of hyper-ammonia-producing species, except for H0.1 on Clostridium aminophilum. It was concluded that dietary supplementation with hainanmycin could improve ruminal fermentation and modify protein degradation by changing population size of ammonia-producing bacteria in vitro; and the addition level of 10 mg/kg appeared to achieve the best results.

Abstract
BACKGROUND Congenital hypothyroidism (CH) is a neonatal endocrine disease with an incidence of 1:2000 to 1:4000 worldwide. In about 85% of patients CH is secondary to thyroid dysgenesis, but its pathogenesis remains unclear. Thyroid transcription factors, such as paired box transcription factor 8 (PAX8), play an important role in thyroid organogenesis and development. AIM To screen PAX8 mutations in Chinese CH patients and characterize the features of PAX8 mutations in China. MATERIALS AND METHODS Blood samples were collected from 300 CH patients in Shandong Province, China, and genomic DNA was extracted from peripheral blood leukocytes. Using PCR and direct sequencing, exon 3 and exon 4 of PAX8 were analyzed. RESULTS Analysis of PAX8 in 300 CH patients revealed heterozygous missense mutations or variations in two unrelated patients; one was a known missense mutation G92A, resulting in an arginine to histidine substitution at codon 31, the other was a missense variation G122T, resulting in the substitution of a glycine at position 41 by a valine residue. The patient with the R31H mutation had CH with thyroid hypoplasia, while the patient with the G41V variation had CH with a eutopic and normal-sized thyroid gland. CONCLUSION We report a heterozygous missense mutation and a variation in PAX8 in two out of 300 unrelated Chinese CH patients, showing that the PAX8 mutation rate is very low in CH patients in China.

Abstract
We developed EST-PCR markers specific to barley chromosome 2H, for the purpose of effectively tracing alien chromosomes or chromosome parts in the wheat genetic background. The target alien chromosome 2H confers high resistance to pre-harvest sprouting, which is a worldwide natural disaster in wheat. A total of 120 primer pairs were selected by combining the wheat group 2 chromosomes of the EST database and the genome sequences of the new model plant Brachypodium distachyon. Seventy-seven of 120 primer pairs were polymorphic and 31 of 120 primer pairs were monomorphic between a set of wheat-barley chromosome 2H disomic addition/substitution lines and their parents by agarose gel electrophoresis and polyacrylamide gel electrophoresis. Thirty of 77 polymorphic primer pairs including primer pair P120 derived from the basi gene were chromosome 2H-specific. These markers are expected to be valuable in screening of wheat-barley chromosome 2H recombination lines and pre-harvest sprouting resistant varieties.

Abstract
OBJECTIVES To investigate the key factors in and gap between perception and performance of daily blood glucose monitoring, regular exercise and diet control in individuals with type 2 diabetes, and to help develop patient-centric healthcare management strategies. STUDY DESIGN Cross-sectional study. METHODS A focus group interview was conducted and questionnaires were collected from outpatients with type 2 diabetes. Paired sample t-tests, importance-performance gap analysis and regression analysis were performed. RESULTS Perseverance was the key factor affecting blood glucose monitoring and regular exercise; the association was stronger in men than women. The critical factor in diet control was the desire to eat. Patients' perceived severity of diabetes and limited daily activities due to diabetes correlated with regular exercise, patients' compliance correlated with glucose monitoring, and perceived health status correlated with diet control. CONCLUSIONS The cultivation of perseverance and strengthening psychological coping is critical. Health professionals should design tailored services, avoid didactic intervention education programmes, and develop a 'meaning-centred' rather than a 'message-centred' philosophy of exercise. Such a campaign may help to improve self-management and promote health behaviours for people with type 2 diabetes.

Abstract
Scaffolds for tissue engineering require the correct biochemical cues if the seeded cells are to migrate into the scaffold and proliferate. For complex tissues this would require precise patterning of the scaffold structure with the particular biochemical cue required at each location on the scaffold. Electrospray enables the deposition of a wide number of biomolecules onto surfaces and can be used for precise patterning. We assessed the functionality of a key cell-adhesion molecule, fibronectin, after depositing it onto a surface using the electrospray technique. The addition of polypropylene glycol allowed a stable spray to be obtained from solutions with a range of fibronectin concentrations. Immunoassay tests showed that the amount of fibronectin retained on the surface was proportional to that sprayed from the solution. Increasing the surface density of fibronectin deposited onto silicon surfaces enhanced fibroblast attachment. The fibronectin thus appears to have retained its cell attachment functionality after undergoing the electrospray process. Since recent advances allow electrospray to pattern material from solution with micrometre accuracy this may allow materials to be biologically functionalized on a similar scale.

Abstract
A series of expressed sequence tags-derived polymerase chain reaction (EST-PCR) markers specific to chromosome 2Ai#2 from Thinopyrum intermedium were developed in this study using a new integrative approach. The target alien chromosome confers high resistance to barley yellow dwarf virus (BYDV), which is a severe virus disease in wheat. To generate markers evenly distributed on 2Ai#2, a total of 105 primer pairs were designed based on mapped ESTs from 8 bins of wheat chromosome 2B with intron-prediction by aligning ESTs with genomic sequences of the new model plant Brachypodium distachyon. Eight and seven polymorphic markers on the short arm and the long arm of chromosome 2Ai#2, respectively, were obtained with a polymorphism rate of 14.3%. These chromosome 2Ai#2-specific EST-PCR markers were then used in tracing and exploring the structural variation of the alien chromosome in the population derived from the immature embryo culture of the cross between N452, a 2Ai#2(2D) substitution line, and common wheat CB037. Two centric fusion of translocations involving 2Ai#2 short or long arm with wheat chromosome 2D and some new genetic stocks including telosomes with the alien chromosome short or long arm were identified in the SC(3) generations, which provided basic materials to further study the mechanism of the BYDV resistance. BYDV tests in two field seasons suggest that the BYDV resistance was mainly conferred by the short arm, gene interaction on both arms of the alien chromosome was discussed.

Abstract
Superconductivity was recently found in the tetragonal phase FeSe. A structural transformation from tetragonal to orthorhombic (or monoclinic, depending on point of view) was observed at low temperature, but was not accompanied by a magnetic ordering as commonly occurs in the parent compounds of FeAs-based superconductors. Here, we report the correlation between structural distortion and superconductivity in FeSe(1-x) thin films with different preferred growth orientations. The films with preferred growth along the c axis show a strong thickness dependent suppression of superconductivity and low temperature structural distortion. In contrast, both properties are less affected in the films with (101) preferred orientation. These results suggest that the low temperature structural distortion is closely associated with the superconductivity of this material.

Abstract
We present a measurement of the tt production cross section in pp collisions at square root s = 1.96 TeV which uses events with an inclusive signature of significant missing transverse energy and jets. This is the first measurement which makes no explicit lepton identification requirements, so that sensitivity to W --> tau nu decays is maintained. Heavy flavor jets from top quark decay are identified with a secondary vertex tagging algorithm. From 311 pb(-1) of data collected by the Collider Detector at Fermilab, we measure a production cross section of 5.8 +/- 1.2(stat)(-0.7)(+0.9)(syst) pb for a top quark mass of 178 GeV/c2, in agreement with previous determinations and standard model predictions.

Abstract
We search for pair-produced Dirac magnetic monopoles in 35.7 pb(-1) of proton-antiproton collisions at square root s = 1.96 TeV with the Collider Detector at Fermilab (CDF). We find no monopole candidates corresponding to a 95% confidence-level cross-section limit sigma < 0.2 pb for a monopole with mass between 200 and 700 GeV/c2. Assuming a Drell-Yan pair-production mechanism, we set a mass limit m > 360 GeV/c2.

Abstract
We measure the masses of b hadrons in exclusively reconstructed final states containing a J/psi --> mu-mu+ decay using 220 pb(-1) of data collected by the CDF II experiment. We find: m(B+) = 5279.10 +/- 0.41(stat.) +/- 0.36(sys.) MeV/c2, m(B0) = 5279.63 +/- 0.53(stat.) +/- 0.33(sys.) MeV/c2, m(B(s)0) = 5366.01 +/- 0.73(stat.) +/- 0.33(sys.) MeV/c2, m(lambda(b)0) = 5619.7 +/- 1.2(stat.) +/- 1.2(sys.) MeV/c2. m(B+) - m(B0) = -0.53 +/- 0.67(stat.) +/- 0.14(sys.) MeV/c2, m(B(s)0) - m(B0) = 86.38 +/- 0.90(stat.) +/- 0.06(sys.) MeV/c2, m(lambda(b)0) - m(B0) = 339.2 +/- 1.4(stat.) +/- 0.1(sys.) MeV/c2. The measurements of the B(s)0, lambda(b)0 mass, m(B(s)0) - m(B0) and m(lambda(b)0) - m(B0) mass difference are of better precision than the current world averages.

Abstract
We report an observation of the decay B(O)(S) --> D(-)(s)pi(+) in pp collisions at radical S = 1.96 TeV using 115 pb(-1) of data collected by the CDF II detector at the Fermilab Tevatron. We observe 83 +/- 11(stat) B(O)(s) --> D(-)(s)pi(+) candidates, representing a large increase in statistics over previous measurements and the first observation of this decay at a pp collider. We present the first measurement of the relative branching fraction Beta(B(O)(s) --> D(-)(s)pi(+))/Beta(B(0) --> D(-)(pi)(+)) = 1.32 +/- 0.18(stat) +/- 0.38(syst). We also measure Beta(B(+) --> D(0)pi(+))/Beta(B(0) -->D(-)pi(+)) = 1.97 +/- 0.10(stat) +/- 0.21(syst), which is consistent with previous measurements.

Abstract
We searched for scalar bottom quarks 156 pb(-1) of pp collisions at radicalS = 1.96 recorded by the Collider Detector at Fermilab II experiment at the Tevatron. Scalar bottom quarks can be produced from gluino decays in -parity conserving models of supersymmetry when the mass of the gluino exceeds that of the scalar bottom quark. Then, a scalar bottom quark can decay into a bottom quark and a neutralino. To search for this scenario, we investigated events with large missing transverse energy and at least three jets, two or more of which were identified as containing a secondary vertex from the hadronization of quarks. We found four candidate events, where 2.6 +/- 0.7 are expected from standard model processes, and placed 95% confidence level lower limits on gluino and scalar bottom quark masses of up to 280 and 240 GeV/c(2), respectively.

Abstract
We report a measurement of the top-quark mass using events collected by the CDF II detector from pp collisions at square root of s = 1.96 TeV at the Fermilab Tevatron. We calculate a likelihood function for the top-quark mass in events that are consistent with tt --> bl(-)nu(l)bl'+ nu'(l) decays. The likelihood is formed as the convolution of the leading-order matrix element and detector resolution functions. The joint likelihood is the product of likelihoods for each of 33 events collected in 340 pb(-1) of integrated luminosity, yielding a top-quark mass M(t) = 165.2 +/- 6.1(stat) +/- 3.4(syst) GeV/c2. This first application of a matrix-element technique to tt --> bl+ nu(l)bl'- nu(l') decays gives the most precise single measurement of M(t) in dilepton events. Combined with other CDF run II measurements using dilepton events, we measure M(t) = 167.9 +/- 5.2(stat) +/- 3.7(syst) GeV/c2.

Abstract
We report on a measurement of the inclusive jet production cross section as a function of the jet transverse momentum in pp collisions at (square root s)=1.96 TeV using data collected with the upgraded Collider Detector at Fermilab in run II, corresponding to an integrated luminosity of 385 pb-1. The measurement is carried out for jets with rapidity 0.1</yjet/<0.7 and transverse momentum in the range 54<pjetT<700 GeV/c. Next-to-leading order perturbative QCD predictions are in good agreement with the measured cross section after the necessary nonperturbative parton-to-hadron corrections are included.

Abstract
We measure the dipion mass spectrum in X(3872)--> J/psipi(+) pi(-) decays using 360 pb(-1) of pp collisions at square root s= 1.96 TeV collected with the CDF II detector. The spectrum is fit with predictions for odd C-parity ((3)S(1), (1)P(1), and (3)D(J)) charmonia decaying to J/psipi(+) pi(-), as well as even C-parity states in which the pions are from rho(0) decay. The latter case also encompasses exotic interpretations, such as a D(0)D(*0) molecule. Only the (3)S(1) and J/psirho hypotheses are compatible with our data. Since (3)S(1) is untenable on other grounds, decay via J/psirho is favored, which implies C= +1 for the X(3872). Models for J/psi - rho different angular momenta L are considered. Flexibility in the models, especially the introduction of rho - omega interference, enables good descriptions of our data for both L = 0 and 1.

Abstract
We present a search for Higgs bosons decaying into bb and produced in association with W bosons in pp collisions at square root of s = 1.96 TeV. This search uses 320 pb(-1) of the data set accumulated by the upgraded Collider Detector at Fermilab. Events are selected that have a high-transverse momentum electron or muon, missing transverse energy, and two jets, at least one of which is consistent with the hadronization of a b quark. Both the number of events and the dijet mass distribution are consistent with standard model background expectations, and we set 95% confidence level upper limits on the production cross section times branching ratio for the Higgs boson or any new particle with similar decay kinematics. These upper limits range from 10 pb for mH = 110 GeV/c2 to 3 pb for mH = 150 GeV/c2.

Abstract
We report the first evidence for a fully reconstructed decay mode of the B(c)+- meson in the channel B(c)+- --> J/psi pi+-, with J/psi --> mu+ mu-. The analysis is based on an integrated luminosity of 360 pb(-1) in pp collisions at 1.96 TeV center of mass energy collected by the Collider Detector at Fermilab. We observe 14.6 +/- 4.6 signal events with a background of 7.1 +/- 0.9 events, and a fit to the J/psi pi+-mass spectrum yields a B(c)+- mass of 6285.7 +/- 5.3(stat) +/- 1.2(syst) MeV/c2. The probability of a peak of this magnitude occurring by random fluctuation in the search region is estimated as 0.012%.

Abstract
We report the results of a search for a charged Higgs boson in the decays of top quarks produced in pp collisions at a center-of-mass energy of 1.96 TeV. We use a data sample corresponding to an integrated luminosity of 193 pb-1 collected by the upgraded Collider Detector at Fermilab. No evidence for charged Higgs production is found, allowing 95% C.L. upper limits to be placed on BR(t-->H+b) for different charged Higgs decay scenarios. In addition, we present in the minimal supersymmetric standard model (mH+/-, tanbeta) plane the first exclusion regions with radiative and Yukawa coupling corrections.
