Abstract
OBJECTIVE The incidence of melanoma is increasing. Other than limiting UV exposure, few factors prevent or reduce the risk of melanoma. The aim of this study is to evaluate the relationship between vitamin D intake and melanoma risk in the Prostate, Lung, Colorectal, and Ovarian (PLCO) cancer screening trial. METHODS A secondary data analysis was performed on PLCO data. More than 1,300 participants developed melanoma. RESULTS Melanoma risk may be increased among men within the highest quartile of vitamin D intake (HR 1.27, 95% CI 0.99, 1.61). Women in the highest quartile of vitamin D intake had a decreased risk of invasive melanoma (HR 0.63, 95% CI 0.41, 0.96). Higher education and being white corresponded with deeper tumors (P < .001). CONCLUSION High reported vitamin D intake resulted in an increased risk of melanoma among men. Vitamin D intake yielded a protective effect against invasive melanoma in women.

Abstract
Photo-plethysmography (PPG) making use of a monochromic light source and a photoelectric sensor is a non-invasive detection method to record blood volume changes in vessels and can be used to extract cardiac-related heart pulse information. Here, we demonstrated the fabrication of a monolithic photonic chip by integrating light-emitting diodes (LEDs) with photodetectors (PDs) on the same GaN-on-sapphire wafer containing InGaN/GaN multi-quantum wells (MQWs). The MQWs simultaneously act as light emitters in the LEDs and detectors in the PDs, and their mechanism has been studied. The fabricated chip operating in reflection mode is flip-chip bonded on a flexible polydimethylsiloxane (PDMS) strip, enabling the sapphire surface in close contact with the skin. The optical and electrical properties of the LED and PD have been thoroughly characterized, confirming that the PDs using identical MQWs can detect the reflected light from the LEDs. By attaching the chip to the wrist, PPG heart pulse signals from the arterial blood flow can be obtained, thereby verifying the feasibility of the proposed monolithic chip.

Abstract
Ultraviolet radiation (UVR) exposure is a primary risk factor for the development of melanoma. However, adults and adolescents often do not engage in preventive behaviors to reduce UVR exposure. Rural residents may be at higher risk for melanoma due to lower use of sun protection strategies, which increases their overall UVR exposure compared to those who live in urban areas. The purpose of this study was to evaluate differences in UVR exposure between rural and urban residents in a geographic area with high incidence of melanoma. Children (aged 8-17 years) and adults (≥ 18 years) from rural and urban areas of Utah were asked to wear a UVR monitoring device for 14 days. The sample included 97 children and 97 adults. Data was collected from June to October 2018. Non-parametric Mann-Whitney tests and quantile regression were used to compare UVR exposure levels between urban and rural participants, separately for adults and children. For adults, rural residence significantly increased total UVR dose ( β: 24.6; 95% CI 3.75, 42.74) and the UVR dose during peak UVR hours among participants with the highest UVR doses (β: 16.3; 95% CI 17.4, 24.63). Rural children exhibited significantly higher UVR doses for peak UVR hours for the entire study period (β: 4.14; 95% CI 0.83, 7.46) and on weekdays (β: 0.39; 95% CI 0.05, 0.73). The findings from this study indicate that rural residents may receive higher levels of UVR exposure than urban residents, and that prevention efforts could be tailored to address these geographical differences.

Abstract
Melanoma is the deadliest form of skin cancer. Screening can aid in early disease detection, when treatment is more effective. Although there are currently no consensus guidelines regarding skin screening for pediatric populations with elevated familial risk for melanoma, at-risk children with the help of their parents and healthcare providers may implement skin self-exams. Healthcare providers may also recommend screening practices for these children. The goal of the current study was to describe current screening behaviors and provider recommendation for screening among children of melanoma survivors. Parents of children with a family history of melanoma completed a questionnaire that included items on children's screening frequency, thoroughness, and who performed the screening. Seventy-four percent of parents reported that their children (mean age = 9.0 years, SD = 4.8) had engaged in parent-assisted skin self-exams (SSEs) in the past 6 months. Only 12% of parents reported that children received SSEs once per month (the recommended frequency for adult melanoma survivors). In open-ended responses, parents reported that healthcare providers had provided recommendations around how to conduct SSEs, but most parents did not report receiving information on recommended SSE frequency. Twenty-six percent of parents (n = 18) reported that children had received a skin exam by a healthcare provider in the past 6 months. The majority of children with a family history of melanoma are reportedly engaging in skin exams despite the lack of guidelines on screening in this population. Future melanoma preventive interventions should consider providing families guidance about implementing screening with their children.

Abstract
PURPOSE Survivorship care plans (SCPs) are used to facilitate communication between oncology and primary care providers (PCPs) after cancer treatment and to assist cancer survivors with healthcare decisions. We evaluated pediatric oncology providers' experiences creating and delivering SCPs. We also evaluated PCPs' opinions of SCPs. METHODS Together, oncology nurses and oncologists created individualized SCPs for leukemia patients treated at a children's hospital in Utah, with nurses in charge of inputting the majority of SCP content. We surveyed providers after each SCP was completed. We also mailed SCPs to PCPs with a survey on SCP content and their knowledge and comfort level caring for cancer survivors. Descriptive statistics were used to summarize survey content. RESULTS A total of 6 nurses and 8 oncologists created 21 SCPs. On average, nurses assisted with 3.5 SCPs and spent 209 min (range 100-600 min) on completing their sections of each SCP, whereas oncologists assisted with 2.6 SCPs and spent 47.4 min (range 15-120). For most SCPs, there was agreement that they should be shared with PCPs (nurse surveys 71.4%, oncologist surveys 100%). Of the 15 participating PCPs, only 28% felt prepared to manage long-term effects in pediatric cancer survivors. They agreed that the SCP would improve communication with their patient's oncologist (80%) and their knowledge for future care (100%). CONCLUSIONS SCPs require substantial clinician time to create, but are seen as useful by PCPs. PCPs require specific guidelines and resources concerning ongoing care for pediatric cancer survivors.

Abstract
BACKGROUND In the United States, melanoma is the 5th most common cancer. Reducing ultraviolet radiation (UVR) exposure is essential for the prevention of melanoma. Objectively assessing individual-level UVR exposure with the use of wearable technology offers a promising tool for reducing UVR exposure. However, the feasibility and acceptability of using UVR monitoring wearable devices have not been assessed. OBJECTIVE The aim of this study was to assess the feasibility and acceptability of a commercially available UVR monitoring wearable device among adults and children. METHODS The study recruited families (one parent and one child) to test a new, commercially-available UVR monitoring device (Shade). Participants wore the Shade device for two weeks and completed questionnaires assessing the feasibility and acceptability of wearing the device. Qualitative analyses were conducted to summarize participants' open-ended responses regarding device feasibility. RESULTS A total of 194 individuals (97 adults and 97 children) participated. Participating children were on average 12.7 years old. Overall, adults and children reported moderate satisfaction with wearing the Shade device. Feasibility of use of the Shade device was adequate with 73% of adults and 61% of children reporting that they wore the device "all of the time they were outside." Through open-ended responses, participants reported appreciating the device's ease of use, compact size, and that it increased their awareness about their UVR exposure. CONCLUSIONS A new, wearable UVR monitoring device can be feasibly used by adults and children and use of the device was acceptable to participants. The device could be integrated into melanoma preventive interventions to increase individual's and families' awareness of their UVR exposure and to facilitate the use of recommended melanoma preventive strategies.

Abstract
PURPOSE To identify the optimal acquisition time to best discriminate between benign and malignant breast lesions on contrast-enhanced cone beam CT (CE-CBCT) and evaluate the potential of CE-CBCT to differentiate between breast cancer subtypes. MATERIAL AND METHOD A total of 98 women with a mean age of 49±10 (SD) years (range: 29-77 years) with 100 BI-RADS 4 or 5 breast lesions were prospectively included. CE-CBCT images were obtained at 1- and 2-min after intravenous administration of iodinated contrast material. Contrast enhancement of breast lesions on CE-CBCT were evaluated and compared between different subtypes. Cut-off values for best discriminating between benign and malignant breast lesions with CE-CBCT were obtained from receiver operating characteristic curves. RESULTS Malignant breast lesions showed greater enhancement than benign ones at 1-min (67.28±39.79 [SD] HU vs. 42.27±40.31 [SD] HU, respectively; P=0.007) and 2-min (70.93±38.05 [SD] HU vs. 48.94±41.83 [SD] HU, respectively; P=0.016) after intravenous administration of contrast material. At 1-min after intravenous administration of contrast material, an optimal cut-off value of 54.43 HU was found to best discriminate between malignant and benign breast lesions (AUC=0.681; 95%CI: 0.558-0.805; P=0.006) yielding 69.0% sensitivity (95%CI: 56.9-79.5%) and 69.2% specificity (95% CI: 48.2-85.7%). At 2-min, an optimal cut-off value of 72.65 HU was found to best discriminate between malignant and benign breast lesions (AUC=0.654; 95%CI: 0.535-0.774; P=0.020) yielding 50.7% sensitivity (95%CI: 38.6-62.8%) and 80.8% specificity (95%CI: 60.6-93.4%). CE-CBCT helped differentiate between immunohistochemical subtypes of breast lesions with lowest enhancement for triple negative lesions. No differences in enhancement were found among histopathological subtypes lesions at 1-min (P=0.478) and 2-min (P=0.625). CONCLUSION CE-CBCT helps discriminate between malignant and benign breast lesions, with best capabilities obtained at 1-min after intravenous administration of contrast material. For malignant lesions, quantitative analysis of enhancement on CE-CBCT helps differentiate between immunohistochemical subtypes.

Abstract
Preventing melanoma, the most serious form of skin cancer, is an important cancer control priority. This is especially true among children living in families previously affected by the disease because the risks for melanoma typically begin early in life. These risks accrue into adulthood but may be mitigated by parental intervention. Melanoma prevention behaviors that could be associated between adults and their children include use of sunscreen, protective clothing, seeking shade, or limiting sun exposure. This study sought to investigate how parent perceptions and behaviors influence sun protection and avoidance behaviors in their children, among relatives of melanoma survivors. In this cross-sectional study, parents (N = 313), all relatives of people diagnosed with melanoma, were surveyed about their melanoma risk-reduction behaviors and efforts to protect their children from sun exposure. Linear multiple regressions examined associations among parental behaviors, beliefs, and their reports of risk reduction for their children. Parents who practiced high sun protection themselves (i.e., wearing protective clothing, avoiding the sun, using sunscreen) were significantly more likely to report their child also wore protective clothing (B = 0.04, p < .004). Findings suggest that parents' use of risk-reducing behavioral measures extended to protective measures among their children. These findings have implications for the clinical care of melanoma survivors' families, including the design of targeted interventions that alter parental beliefs and behaviors surrounding both their own and their children's cancer prevention strategies.

Abstract
Multicomponent skin cancer preventive interventions for adolescents that aim to decrease ultraviolet radiation (UVR) exposure and sunburns are particularly needed given their intentional tanning and infrequent use of sun protection. The purpose of this study was to conduct an early-phase study within the Multiphase Optimization Strategy framework that experimentally tested four unique intervention components targeting high school students' skin cancer prevention behaviors. Schools (11 total, N = 1,573 students) were assigned to receive one of four interventions: skin cancer education (control), education plus a sunscreen activity (to illustrate sunscreen's UVR-blocking properties), or behavior change worksheet (sun protection goal setting and planning) or receipt of a personalized UV damage photograph (photograph of facial damage). Sun protection, sunburn, and tanning outcomes were assessed before intervention and at 1-month follow-up. Within- and between-intervention changes in outcomes were examined using generalized estimating equation modeling. All interventions were associated with significant improvements in sun protection. The photograph was superior in controlling intentional tanning and sunburn when compared to the behavior change worksheet (ps < .05). In contrast, the worksheet was associated with greater increases in sun protection use when compared with the photograph (ps < .05). In this experiment testing four skin cancer preventive intervention components that varied in approach, content, and interactivity, the behavior change worksheet was superior in improving sun protection use whereas the UV photograph was superior in controlling intentional tanning and sunburn. Future randomized trials to test combinations of these intervention components are needed, and could identify mechanisms underlying improved effects and demographic or behavioral moderators of intervention effects.

Abstract
OBJECTIVE Melanoma preventive interventions for children with familial risk are critically needed because ultraviolet radiation (UVR) exposure and sunburn occurrence early in life are the primary modifiable risk factors for melanoma. The current study examined the feasibility and acceptability of a new, family-focused telehealth intervention for children with familial risk for melanoma and their parents. The study also explored changes in child sun protection and risk behaviors, sunburn occurrence, and objectively measured UVR exposure. METHODS This was a prospective study with a single-group design (n = 21 parent-child dyads, children ages 8-17). Dyads were asked to participate in three in-person assessments and three live video teleconference intervention sessions. RESULTS The intervention was feasibly delivered, and the intervention content was acceptable to parents and children. The intervention was associated with improvements in child use of certain sun protection strategies over time and declines in child UVR exposure. CONCLUSIONS A telehealth-delivered,family-focused melanoma preventive intervention was feasibly delivered and was acceptable to parent-child dyads. Future melanoma preventive interventions for this at-risk population could incorporate eHealth technologies to facilitate improvements in use of sun protection and monitoring of UVR exposure. This trial was registered with Clinicaltrials.gov, number NCT02846714.

Abstract
Individuals residing in U.S. frontier counties have limited access to dermatology care and higher melanoma mortality rates. Given these limitations, frontier residents rely disproportionately on skin self-examinations (SSE) for early detection of melanoma, though little is known about their SSE behaviors and barriers to conducting SSEs. The goal of the present study was to identify obstacles to SSE performance via a survey of adults (N = 107) living in a U.S. frontier county. Approximately 43% of participants were classified as inclined abstainers - individuals who intended to perform SSE, but failed to follow through. Compared to those who did follow through, inclined abstainers were more likely to be hindered by twelve barriers, including forgetting, letting other tasks get in the way of SSE, and struggling to identify a good time or routine for SSE performance. The barriers to action for these inclined abstainers are modifiable - for example, not remembering to do it - and well positioned for a behavioral intervention.

Abstract
PURPOSE The purpose of the current study was to evaluate differences in reported use of sun protection, tanning behaviors, skin cancer-related knowledge, and perceived risk between rural and urban high school students in a geographic area with high rates of melanoma. METHODS A total of 1,570 high school students (56.8% female) from urban (6 schools) and rural (7 schools) geographic areas in Utah completed questionnaires assessing sun protection and tanning behaviors, skin cancer-related knowledge, and perceived risk for skin cancer. Analyses examined potential differences in these outcomes between rural and urban students and by gender. RESULTS Compared to students in urban areas, those in rural areas had lower odds of wearing sunscreen (OR 0.71; 95% CI 0.53, 0.95; p = 0.022), re-applying sunscreen (OR 0.61; 95% CI 0.74, 1.02; p = 0.002), wearing long-sleeved shirts (OR 0.63 95% CI 0.46, 0.86; p = 0.004), and seeking shade (OR 0.67; 95% CI 0.50, 0.88; p = 0.005). CONCLUSIONS Rural students reported less adequate use of sun protection than urban students. Rural male students reported lower knowledge scores compared to urban males. Future skin cancer prevention efforts targeting rural high schoolers are warranted.

Abstract
This narrative review describes the evidence regarding digital health interventions targeting adolescent and young adult (AYA) cancer survivors. We reviewed the published literature for studies involving Internet, mHealth, social media, telehealth, and other digital interventions for AYA survivors. We highlight selected studies to illustrate the state of the research in this unique patient population. Interventions have used various digital modalities to improve health behaviors (eg, physical activity, nutrition, tobacco cessation), enhance emotional well-being, track and intervene on cancer-related symptoms, and improve survivorship care delivery. The majority of studies have demonstrated feasibility and acceptability of digital health interventions for AYA survivors, but few efficacy studies have been conducted. Digital health interventions are promising to address unmet psychosocial and health information needs of AYA survivors. Researchers should use rigorous development and evaluation methods to demonstrate the efficacy of these approaches to improve health outcomes for AYA survivors.

Abstract
Background Endometrial cancer is the second most common cancer among female cancer survivors in the United States. Cardiovascular disease is the leading cause of death among endometrial cancer survivors. Studies that examine long-term cardiovascular outcomes among endometrial cancer survivors are critical. Methods Cohorts of 2648 endometrial cancer survivors diagnosed between 1997 and 2012 and 10 503 age-matched women from the general population were identified. Cardiovascular disease diagnoses were identified from electronic medical records and statewide ambulatory surgery and statewide inpatient data. Cox regression models were used to estimate hazard ratios (HRs) at one to five years, more than five to 10 years, and more than 10 years after cancer diagnosis. Results Between one and five years after diagnosis, increased cardiovascular risks among endometrial cancer survivors were observed for phlebitis, thrombophlebitis, and thromboembolism (HR = 2.07, 99% confidence interval [CI] = 1.57 to 2.72), pulmonary heart disease (HR = 1.74, 99% CI = 1.26 to 2.40), and atrial fibrillation (HR = 1.50, 99% CI = 1.07 to 2.11). At more than five to 10 years, some elevated risk persisted for cardiovascular diseases. Compared with patients who had surgery, patients who additionally had radiation therapy and/or chemotherapy were at increased risk for heart and circulatory system disorders between one and five years after cancer diagnosis. Older age and obesity were also risk factors for hypertension and heart disease among endometrial cancer survivors. Conclusions Endometrial cancer survivors are at higher risk for various adverse long-term cardiovascular outcomes compared with women from the general population. This study suggests that increased monitoring for cardiovascular diseases may be necessary for endometrial cancer patients for 10 years after cancer diagnosis.

Abstract
Melanoma prevention is essential for children who are at elevated risk for the disease due to family history. However, children who carry a familial risk for the disease do not optimally adhere to recommended melanoma preventive behaviors. The current study sought to identify perceived barriers to and facilitators of children's engagement in melanoma preventive behaviors among children at elevated risk for melanoma due to family history of the disease (i.e., having a parent with a history of melanoma) from both parents' and childrens' perspectives. Qualitative methods were employed and consisted of separate focus group discussions with children (ages 8-17 years, n = 37) and their parents (n = 39). Focus group transcripts were coded using content analysis. Parents and children reported a number of barriers and facilitators, including on the individual (e.g., knowledge and awareness, preferences), social (e.g., peer influences, family modeling and communication), and contextual (e.g., healthcare provider communication) levels. The identified categories of barriers and facilitators both confirm and extend the literature documenting the reasons children who are at elevated risk for melanoma do not engage in melanoma prevention and control behaviors. Programs aiming to decrease melanoma risk among children of melanoma survivors could help families address their barriers to preventive behavior implementation and build on facilitators. Melanoma survivors and their children could benefit from support on their interactions with healthcare providers, schools, peers, and other caregivers about melanoma prevention.

Abstract
OBJECTIVE To provide a primer on conducting and analyzing mixed methods research studies, and to provide guidance on the write-up of mixed methods research. METHODS A question and answer format is used to provide an overview of mixed methods research study designs, tasks and considerations related to conducting and analyzing mixed methods studies, and recommendations for the write-up of results for mixed methods studies. RESULTS Individuals who conduct mixed methods research are encouraged to delineate the quantitative, qualitative, and mixed methods features of the research and how these features fit with the overall study questions. Research teams will benefit from including individuals with expertise in qualitative, quantitative, and mixed methods research. Data integration should be a central component to the analysis and write-up of mixed methods research. CONCLUSIONS Increasing the use of mixed methods research in the field of pediatric psychology will contribute to advances in observational studies with children and families, intervention development and evaluation, and creation of new tools and assessments that aim to optimize child and family health outcomes.

Abstract
Ultraviolet (UV) photos reveal the world in a different light spectrum, including damage that is caused by UV light. In the context of skin cancer control, UV photos have the potential to communicate fear because they reveal underlying skin damage. U.S. adults (N = 2219) were assigned to a 5 (visual: UV skin damage, sun exposure, sunburn, photoaging, and mole removal) × 3 (replication: three examples of each visual condition) × 4 (efficacy: no efficacy, text only, visual, visual + text) randomized controlled trial. Compared to all other visual conditions combined, UV skin damage visuals generated greater fear which triggered increased sun safe behavior expectations. Compared with other visual conditions separately, only mole removal visuals produced equivalent fear as UV skin damage visuals. Visual efficacy conditions appeared to nullify rather than magnify the indirect path through fear. The results suggest one way UV images impact sun safe behavioral expectations is via fear and that researchers should continue to examine the position of fear in fear appeal theories.

Abstract
Plasma-based accelerators have made impressive progress in recent years. However, the beam energy spread obtained in these accelerators is still at the ∼1% level, nearly one order of magnitude larger than what is needed for challenging applications like coherent light sources or colliders. In plasma accelerators, the beam energy spread is mainly dominated by its energy chirp (longitudinally correlated energy spread). Here we demonstrate that when an initially chirped electron beam from a linac with a proper current profile is sent through a low-density plasma structure, the self-wake of the beam can significantly reduce its energy chirp and the overall energy spread. The resolution-limited energy spectrum measurements show at least a threefold reduction of the beam energy spread from 1.28% to 0.41% FWHM with a dechirping strength of ∼1 (MV/m)/(mm pC). Refined time-resolved phase space measurements, combined with high-fidelity three-dimensional particle-in-cell simulations, further indicate the real energy spread after the dechirper is only about 0.13% (FWHM), a factor of 10 reduction of the initial energy spread.

Abstract
Health promotion during early life and childhood can reduce the prevalence and impact of acute and chronic health conditions later in life. Research regarding factors that influence child and family health, prevention, and intervention programs that address them, and policies that promote implementation of best practices are needed to efficiently and effectively address the multi-faceted, biopsychosocial influences on child health, especially among youth from underserved backgrounds. The current special issue dedicated to child and family health offers a series of articles that illustrate how explanatory studies and targeted intervention programs for children, families, health care providers, and communities can be used to improve child health. Articles in this special issue are organized into three areas related to child and family health: (i) diet and nutrition, (ii) cancer prevention and control, and (iii) social determinants of health and health care. The articles included in this special issue underscore that behavioral medicine practitioners, researchers, and policy makers are well poised to lead innovative efforts to promote child health across clinical, community, health care, and population settings.

Abstract
BACKGROUND/OBJECTIVES Children with an elevated familial risk for melanoma inconsistently implement sun protection behaviors that could mitigate their melanoma risk. Little is known about perceived barriers to child sun protection among this at-risk group and their parents, and the extent to which perceived barriers are associated with child sun protection. The goal of this study was to examine, among children with a family history of melanoma, the frequency with which children and their parents reported barriers to child sun protection and the extent to which barriers were associated with reported use of sun protection among children. METHODS Children with a family history of melanoma and their parents completed questionnaires assessing perceived barriers and reported child use of sun protection. RESULTS Common barriers to child sun protection included being bothered by implementing the behavior or forgetting. A greater number of perceived barriers were associated with less frequent child use of sunscreen, long-sleeved shirts, long pants, and shade. CONCLUSIONS Children at elevated risk for melanoma due to a family history of the disease and their parents perceive multiple barriers to sun protection that are associated with children's use of these melanoma preventive behaviors. Sun protection interventions for this at-risk population could provide families with specific strategies to address common barriers to implementing child sun protection.

Abstract
BACKGROUND As survivorship care plan (SCP) use among childhood cancer survivors and their families has not been extensively researched, we report on their experiences with receiving an SCP after the completion of therapy. METHODS Eligible patients had acute lymphoblastic leukemia, completed therapy, and had no evidence of disease at enrollment. Patients aged 7 or older (N = 13) and at least one parent (N = 23 for 20 total patients) were surveyed and completed assessments at enrollment (Time 1, T1), SCP delivery (Time 2, T2), and follow-up (Time 3, T3) (retention 90.9%). Surveys assessed the delivery process and SCP format. McNemar tests were used to assess change from T2-T3. RESULTS Satisfaction with the SCP was generally high among parents. At T1 the majority of parents (69.6%) thought the SCP should be delivered after treatment but by T3 most preferred the plan to be delivered before the end of treatment (60.9%). While 95.7% of parents intended to share their child's SCP with another provider, family, or school at T2, only 60.9% had done so by T3 (P < 0.01). At both T2 and T3, 100% of parents agreed that the SCP would help make decisions about their child's future health care. Most patients at T3 (83.3%) felt they had learned something new from their SCP. CONCLUSIONS Pediatric oncology patients and families feel SCPs are useful and will help them make decisions about health care in the future.

Abstract
In order to investigate the diagnostic value of serum levels of tartrate-resistant acid phosphatase 5b (TRACP5b) in patients with bone tumors, enzyme linked immunosorbent assay (ELISA) was used to com¬pare serum levels of TRACP5b and alkaline phosphatase (ALP) in bone tumor patients (experimental group, 80 cases) and healthy controls (control group, 36 cases). It was found that the serum level of TRACP5b in the experimental group was significantly higher than that in the control group. In addition, the sensitivity and specificity of serum TRACP5b were higher than those of serum ALP in the diagnosis of bone tumors. Fur¬thermore, the serum level of TRACP5b was positively correlated with that of ALP. Therefore, it was conclud¬ed that the serum level of TRACP5b may be used as a sensitive indicator of bone tumors, and the sensitivity and specificity of TRACP5b are even higher than those of ALP in the diagnosis of bone tumors.

Abstract
Objective: To explore the effects of various forms of prostatic apex on positive apical margin rate (PAM) and biochemical recurrence (BCR) after laparoscopic radical prostatectomy. Methods: A retrospective analysis of 309 patients (aging (65±6) years) who were experienced laparoscopic radical prostatectomy from January 2010 to December 2016 at the Department of Urology, First Affiliated Hospital of Fujian Medical University. According to the relationship between prostate apex and membrane urethra at the mid-sagittal plane of preoperative MRI, all patients were classified into 4 categories. There were 31 patients for type 1, apex covering both anterior and posterior aspects of membranous urethra, 139 patients for type 2, apex covering anterior side of membranous urethra, 63 patients for type 3, apex covering posterior aspect of membranous urethra, 76 patients for type 4, apex not covering membranous urethra. PAM and BCR after operation were compared between this four groups respectively. The χ(2) test was used to compare PAM among the 4 types. Logistic regression analysis were undertaken to analyze the factors affecting PAM. Cox's proportional hazards regression model was undertaken to identify the variables influencing BCR. Results: There was no significant difference in the 4 groups concerning age, body mass index, prostate volume, preoperative prostate-specific antigen (PSA) value, postoperative Gleason score and pathological stage (P>0.05).The median follow-up time was 32 months (ranged from 12 to 60 months).The data showed that the apical type 3 patients has the highest PAM. There was statistical difference among the 4 groups in PAM (χ(2)=15.592, P=0.001). Preoperative level of PSA (OR=20.356, 95% CI: 2.440 to 169.810, P=0.005), postoperative Gleason score (OR=4.113, 95% CI: 1.911 to 8.849, P=0.001), pathological stage (OR=3.422, 95% CI: 1.600 to 7.319, P=0.002) and apical type 3 (OR=6.134, 95% CI: 2.196 to 17.132, P=0.001) were independent relactive factors of PAM. Preoperative level of PSA (HR=1.362, 95% CI: 1.006 to 1.843, P=0.045), postoperative Gleason score (HR=1.920, 95% CI: 1.384 to 2.665, P=0.001), pathological stage (HR=1.476, 95% CI: 1.098 to 1.983, P=0.010), PAM (HR=3.497, 95% CI: 2.407 to 5.081, P=0.001)and apical type 3 (HR=1.828, 95% CI: 1.266 to 2.639, P=0.001) were independent prognosis factors of BCR. Conclusion: Prostate apical type 3 could be a significant independent predictor of PAM, and an independent prognosis factor for BCR.

Abstract
Objective: To explore the regulatory mechanism of E2F1 transcription factor on M2 macrophages in full-thickness skin defect wounds of mice. Methods: E2F1 gene knockout heterozygotes C57BL/6 mice and wild-type C57BL/6 mice were introduced and self-reproduced. Two weeks after birth, E2F1 gene knockout homozygotes mice and wild-type mice were identified by polymerase chain reaction (PCR). Twelve identified 6-8 weeks old male E2F1 gene knockout homozygotes C57BL/6 mice and wild-type C57BL/6 mice were selected respectively according to the random number table and set as E2F1 gene knockout group and wild-type group. A full-thickness skin defect wound was made on the back of each mouse. On post injury day (PID) 2 and 7, 6 mice in each group were selected according to the random number table and sacrificed, and the wound tissue was excised. The expression of CD68 and CD206 double positive M2 macrophages was observed by immunofluorescence method, and the percentage of CD206 positive cells was calculated. The protein expression of CD206 was detected by Western blotting. The mRNA expression of arginase 1 was detected by real-time fluorescent quantitative reverse transcription PCR (RT-PCR). Wound tissue specimens of the two groups on PID 7 were obtained, and the protein and mRNA expressions of peroxisome proliferator-activated receptor gamma (PPAR-γ) were detected by Western blotting and real-time fluorescent quantitative RT-PCR respectively. The above-mentioned experiments were repeated four times. Three specimens of wound tissue of mice in wild-type group on PID 7 were obtained to detect the relationship between E2F1 and PPAR-γ by co-immunoprecipitation and Western blotting, and this experiment was repeated two times. Data were processed with unpaired t test. Results: The size of PCR products of E2F1 gene knockout homozygotes C57BL/6 mice and wild-type C57BL/6 mice were 227 and 172 bp respectively, which were the same as those of the designed DNA fragments. On PID 2 and 7, the number of CD68 and CD206 double positive M2 macrophages in the wound tissue of mice in E2F1 gene knockout group was more than that of wild-type group, and the percentages of CD206 positive cells in the wound tissue of mice in E2F1 gene knockout group were (0.234±0.032)% and (0.584±0.023)% respectively, which were significantly higher than (0.129±0.017)% and (0.282±0.071)% of wild-type group (t=3.29, 3.54, P<0.05). On PID 2 and 7, the protein expression of CD206 in the wound tissue of mice in E2F1 gene knockout group were 1.00±0.23 and 1.63±0.26 respectively, which were significantly higher than 0.43±0.06 and 0.97±0.08 of wild-type group (t=2.41, 2.45, P<0.05). On PID 2 and 7, the mRNA expressions of arginase 1 in the wound tissue of mice in E2F1 gene knockout group were 0.482±0.105 and 0.195±0.031 respectively, which were significantly higher than 0.163±0.026 and 0.108±0.017 of wild-type group (t=3.04, 2.86, P<0.05). On PID 7, the protein and mRNA expressions of PPAR-γ in the wound tissue of mice in E2F1 gene knockout group were 0.61±0.12 and 0.51±0.13 respectively, which were significantly higher than 0.20±0.04 and 0.20±0.04 of wild-type group (t=3.36, 2.86, P<0.05). On PID 7, detection of the wound tissue of mice in wild-type group showed that PPAR-γ had unidirectional effect on E2F1. Conclusions: E2F1 transcription factor affects the polarization of M2 macrophages by inhibiting the expression of PPAR-γ, thereby inhibiting the healing process of full-thickness skin defect wounds in mice.
