Structural Equation Model of Factors Related to Death Anxiety for Chinese Patients with Cancer.

This study aimed to develop a model that specifies the predictive effects of factors on death anxiety among Chinese patients with cancer using structural equation modeling. Using convenience sampling, data were collected from 353 cancer patients. Self-administered questionnaires included Social Support Rating Scale, Rosenberg Self-Esteem Scale, Connor Davidson Resilience Scale, Templer's Death Anxiety Scale, and socio-demographic factors. The results showed that social support, self-esteem, and resilience significantly impacted death anxiety. The final model fitted the data acceptably (χ2 = 37.319, df =31, p = 0.201). Social support mediated death anxiety through self-esteem and resilience. Resilience mediated the buffer effect of self-esteem on death anxiety as an intermediary factor. Findings suggest the need for further studies to explore effective interventions to provide social support and improve self-esteem and resilience among patients with cancer to alleviate death anxiety.

Development of a droplet digital PCR assay for sensitive detection of porcine circovirus 3.

Porcine circovirus 3 (PCV3), a newly emerged circovirus, is associated with porcine dermatitis and nephropathy syndrome, reproductive failure and multi-systemic inflammation disease, and is widely distributed in pig populations worldwide. Therefore, developing specific diagnostic assays will be important for controlling this emerging pathogen. In this study, we developed a novel droplet digital PCR (ddPCR) assay targeting the PCV3 cap gene to improve the sensitivity of PCV3 detection. The established assay is highly specific to PCV3, and does not cross react with other important swine pathogens. The assay's detection limit was 1.68 ±â€¯0.29 copies of PCV3 DNA per reaction (n = 8), an approximately 10-fold greater sensitivity than that of our previously developed quantitative real-time PCR (qPCR) assay for the same virus. The ddPCR assay results were highly reproducible, with intra- and inter-assay coefficient of variation values of <9.0%. Of the 239 archived pig tissue and serum samples, 42 tested positive for PCV3 by the ddPCR assay. Among the 42 positive samples, 31 tested positive by the qPCR assay. Notably, PCV3 was detected in the serum samples collected from commercially imported healthy boars from the US, France and the UK during 2011-2017. The overall agreement between the two assays was 95.39% (228/239). Furthermore, the linear regression analysis showed that the ddPCR and the qPCR results were significantly correlated with an R2 value of 0.9945. Collectively, these results indicate that the ddPCR assay is a robust diagnostic tool for sensitive detection of PCV3, even in samples with low viral loads.

Downregulation of TRIM27 expression inhibits the proliferation of ovarian cancer cells in vitro and in vivo.

TRIM27 (tripartite motif-containing 27) was originally identified as a fusion partner with the RET (REarranged during transfection) proto-oncogene and is highly expressed in various tumor cells and tissues. However, the level of expression and function of TRIM27 in ovarian cancer remain unclear. Here we have measured the expression of TRIM27 in normal ovarian and fallopian tube epithelial cells and in ovarian serous carcinoma cells and correlated TRIM27 expression with clinical and pathological parameters. In addition, we detected the effect of TRIM27 knockdown on proliferation of ovarian cancer cells in cell culture and xenografts. The results demonstrated that TRIM27 was highly expressed in ovarian serous carcinoma cells, and TRIM27 expression was significantly correlated with metastasis and FIGO stage in ovarian serous carcinoma patients. Downregulation of TRIM27 expression suppressed the proliferation of ovarian cancer cells in cell culture and inhibited the growth of xenografts in nude mice. TRIM27 knockdown induced cell cycle arrest and apoptosis in ovarian cancer cells by upregulating the expression of p-P38 and downregulating the expression of p-AKT. Thus the present study suggests that TRIM27 could have important roles as an oncogene during the development of ovarian cancer and could serve as a diagnostic and therapeutic target.

Coastal ecological security assessment in Laizhou Bay, China: from the perspective of demographic-social-economic-natural complex ecosystem.

Assessment of ecological security is essential for understanding the status of bay ecosystem and developing appropriate management strategy. Based on the driving force-pressure-state-impact-response (DPSIR) model, the demographic, economic, social, and ecological data of Laizhou Bay and its three neighboring counties were selected for the period from 2015 to 2021. An ecological security evaluation index system of Laizhou Bay containing 26 indicators was established, and the weights of each indicator were determined by the methods of AHP and EWM, and a comprehensive evaluation of the ecological security of Laizhou Bay was carried out by ESI. Correlations between indicators were analyzed by the Spearman's rank coefficient of correlation. The results showed that there were significant correlations between marine conditions and indicators such as population size in the surrounding area, mariculture area, industrial and domestic wastewater discharge, and treatment rate. Overall, from 2015 to 2021, the ecological security of Laizhou Bay showed a favorable trend, from a relatively unsafe level to a generally safe level, and then to a relatively safe level. Through the comprehensive evaluation of the ecological security of Laizhou Bay, we can recognize the utilization of marine resources and ecological carrying capacity, guide the rational development and utilization of marine resources, and promote the sustainable development of the marine economy.

Design and Implementation of a Four-Unit Array Piezoelectric Bionic MEMS Vector Hydrophone.

High-performance vector hydrophones have been gaining attention for underwater target-monitoring applications. Nevertheless, there exists the mutual constraint between sensitivity and bandwidth of a single hydrophone. To solve this problem, a four-unit array piezoelectric bionic MEMS vector hydrophone (FPVH) was developed in this paper, which has a cross-beam and a bionic fish-lateral-line-nerve-cell-cilia unit array structure. Simulation analysis and optimization in the design of the bionic microstructure have been performed by COMSOL 6.1 software to determine the structure dimensions and the lead zirconate titanate (PZT) thin film distribution. The FPVH was manufactured using MEMS technology and tested in a standing wave bucket. The results indicate that the FPVH has a sensitivity of up to -167.93 dB@1000 Hz (0 dB = 1 V/µPa), which is 12 dB higher than that of the one-unit piezoelectric MEMS vector hydrophone (OPVH). Additionally, the working bandwidth of the FPVH reaches 20 Hz~1200 Hz, exhibiting a good cosine curve with an 8-shape. This work paves a new way for the development of multi-unit piezoelectric vector hydrophones for underwater acoustic detectors.

A retrospective study of the detection of sepsis pathogens comparing blood culture and culture-independent digital PCR.

Fast and precise identification of microorganisms in the early diagnosis of sepsis is crucial for enhancing patient outcomes. Digital PCR (dPCR) is a highly sensitive approach for absolute quantification that can be utilized as a culture-independent molecular technique for diagnosing sepsis pathogens. We performed a retrospective investigation on 69 ICU patients suspected of sepsis. Our findings showed that a multiplex dPCR diagnostic kit outperformed blood culture in detecting the 15 most frequent bacteria that cause sepsis. Ninety-two bacterial strains were identified using dPCR at concentrations varying from 34 copies/mL to 105,800 copies/mL. The detection rate of dPCR was much greater than that of BC, with 27.53% (19/69) versus 73.91% (51/69). The sensitivity of dPCR was 63.2%. Our research indicated that dPCR outperforms blood culture in the early detection of sepsis-causing microorganisms. The diagnostic kit can detect a greater variety of pathogens with quantitative data, including polymicrobial infections, and has a quicker processing time. DPCR is a valuable technique that could aid in the proper management of sepsis.

The influences of the Big Five personality traits on academic achievements: Chain mediating effect based on major identity and self-efficacy.

This study mainly verified the influences of personality traits on students' academic achievements and assessed the mediating effects of major identity and self-efficacy, under the classical model of chain mediating effects, with the data of business major students. The results show that both extraversion and conscientiousness have positive total effect on students' academic achievements, and they are mainly realized through the chain mediating effects of self-efficacy and major identity to self-efficacy, and are mainly based on self-efficacy mediating effect, which is more obvious in the dimension of behavioral efficacy. Openness also affects academic achievement through a self-efficacy mediating effect and major identity to self-efficacy chain mediating effect, but the degree of influence is weak, and the total effect is not significant; the overall effect of agreeableness personality on academic achievement is negative, and it is mainly reflected through direct effect. This finding suggests that academic achievement does not reflect students' team ability and performance.

Efficacy of neurointerventional therapy in patients with ischemic stroke and risk factors affecting cognitive function recovery.

OBJECTIVE: To investigate the efficacy of neurointervention combined with intravenous thrombolysis in ischemic stroke patients and the risk factors affecting cognitive function recovery. METHODS: A total of 114 patients with acute ischemic stroke (AIS) treated in Baoji People's Hospital from January 2017 to December 2020 were retrospectively selected and divided into an observation group and a control group according to different treatment methods. The observation group was treated with neurointervention + intravenous thrombolysis (n = 64), and the control group underwent intravenous thrombolysis (n = 50). The efficacy, recanalization rate, incidence of adverse events, National Institutes of Health Stroke Scale (NIHSS) score, Mini-Mental State Examination (MMSE) score and modified Rankin Scale (mRS) score were evaluated and compared between the two groups. Patients were further divided into a cognitive dysfunction group and a non-disorder group according the MMSE score after treatment, and logistics regression was used to analyze the risk factors of cognitive dysfunction. RESULTS: The overall response rate and the total recanalization rate of the observation group were significantly higher than those of the control group (both P < 0.05). Compared with those before operation, the NIHSS score at 7 d after operation and the mRS score 3 months after operation decreased, while the MMSE score increased in both groups (P < 0.05). The postoperative NIHSS score and mRS score were lower and MMSE score was higher in the observation group than those in the control group (P < 0.05). No significant difference was identified in the incidence of adverse events between the two groups (P > 0.05). Logistics regression analysis revealed that age, diabetes mellitus, hyperlipidemia and lesions at critical sites were independent risk factors for cognitive impairment in patients with AIS. CONCLUSION: Interventional thrombectomy combined with intravenous thrombolysis is effective in the treatment of cerebral infarction. This regimen can reduce neurological deficits and improve the recanalization rate. In addition, age, diabetes, hyperlipidemia and lesions at critical sites are independent risk factors for the development of cognitive impairment in AIS patients.

High-Sensitivity Piezoelectric MEMS Accelerometer for Vector Hydrophones.

In response to the growing demand for high-sensitivity accelerometers in vector hydrophones, a piezoelectric MEMS accelerometer (PMA) was proposed, which has a four-cantilever beam integrated inertial mass unit structure, with the advantages of being lightweight and highly sensitive. A theoretical energy harvesting model was established for the piezoelectric cantilever beam, and the geometric dimensions and structure of the microdevice were optimized to meet the vibration pickup conditions. The sol-gel and annealing technology was employed to prepare high-quality PZT thin films on silicon substrate, and accelerometer microdevices were manufactured by using MEMS technology. Furthermore, the MEMS accelerometer was packaged for testing on a vibration measuring platform. Test results show that the PMA has a resonant frequency of 2300 Hz. In addition, there is a good linear relationship between the input acceleration and the output voltage, with V = 8.412a - 0.212. The PMA not only has high sensitivity, but also has outstanding anti-interference ability. The accelerometer structure was integrated into a vector hydrophone for testing in a calibration system. The results show that the piezoelectric vector hydrophone (PVH) has a sensitivity of -178.99 dB@1000 Hz (0 dB = 1 V/µPa) and a bandwidth of 20~1100 Hz. Meanwhile, it exhibits a good "8" shape directivity and consistency of each channel. These results demonstrate that the piezoelectric MEMS accelerometer has excellent capabilities suitable for use in vector hydrophones.

Circadian Regulator-Mediated Molecular Subtypes Depict the Features of Tumor Microenvironment and Indicate Prognosis in Head and Neck Squamous Cell Carcinoma.

Introduction: Circadian rhythm is involved in multiple biological activities and implicated in cancer development. However, the role of circadian rhythm in head and neck squamous cell carcinoma (HNSCC) has not been fully interpreted yet. Herein, the present study set out to explore the significance of circadian regulator genes (CRGs) in HNSCC. Materials and Methods: The molecular landscape and clinical significance of 13 CRGs in HNSCC were explored based on The Cancer Genome Atlas (TCGA). The biological functions of PER3, a key CRG, were validated by cellular experiments. The correlation of CRGs with microenvironment, pathway activities, and prognosis was determined by bioinformatic algorithms. A novel circadian score was introduced to evaluate the circadian modification pattern of each patient and further validated in an independent cohort from the Gene Expression Omnibus (GEO) dataset. Results: CRGs presented high heterogeneity in HNSCC at both genomic and transcriptomic levels. Specifically, PER3 indicated a better prognosis and inhibited HNSCC cell proliferation. Moreover, HNSCC tissues displayed three circadian regulator patterns with distinct clinical outcomes, transcriptomic characteristics, and microenvironment features. Circadian score was an independent risk factor and exhibited excellent predictive efficiency in both the training cohort from the TCGA database and the validation cohort from the GEO database. Conclusions: CRGs played an indispensable role in HNSCC development. An in-depth exploration of circadian rhythm would improve the understanding of HNSCC carcinogenesis and confer novel insights for future clinical practices.

Characterization of Agronomic and Seed Oil Features for Different Cultivars of Tree Peony.

Tree peony is a unique oil plant resource in China, and tree peony seed oil is one of the healthy edible oils with a very promising future. However, the main oil tree peony cultivars promoted in China are Paeonia ostii 'Fengdan' and Paeonia rockii. In order to explore new oil tree peony cultivars, 68 tree peony cultivars were investigated and cultivars with oil potential were selected by cluster analysis and grey relational analysis (GRA) in this study. The results demonstrated that the 68 cultivars varied significantly in terms of agronomic characteristics (p < 0.05), with the coefficient of variation in seed yield per plant reaching a high of 75.36%. The oil content of 46 cultivars was higher than 'Fengdan' (20.87 ± 0.26%) and 'Zibanbai' (21.24 ± 1.01%), while the alpha-linolenic acids and total unsaturated fatty acid contents of 26 cultivars were higher than 'Fengdan' (39.79 ± 1.13% and 88.99 ± 0.47%) and 'Zibanbai' (40.51 ± 0.09% and 93.59 ± 0.09%). Finally, three cultivars with better integrated traits were selected by cluster analysis and grey relational analysis (GRA), comprising of 'Changshoule', 'Xianchizhenghui', and 'Yupantuojin'. The contents of alpha-linolenic acids and total unsaturated fatty acids in 'Changshoule' (47.98 ± 0.17% and 93.60 ± 0.08%), 'Xianchizhenghui' (49.44 ± 0.63% and 93.80 ± 0.06%), and 'Yupantuojin' (40.46 ± 0.26% and 93.58 ± 0.06%) were higher than that of 'Fengdan' (39.79 ± 1.13% and 88.99 ± 0.47%). In general, these cultivars can be used as hybrid parental materials for breeding new excellent oil tree peony cultivars.

Genome-wide association study of 23 flowering phenology traits and 4 floral agronomic traits in tree peony (Paeonia section Moutan DC.) reveals five genes known to regulate flowering time.

Tree peony is a unique traditional flower in China, with large, fragrant, and colorful flowers. However, a relatively short and concentrated flowering period limits the applications and production of tree peony. A genome-wide association study (GWAS) was conducted to accelerate molecular breeding for the improvement of flowering phenology traits and ornamental phenotypes in tree peony. A diverse panel of 451 tree peony accessions was phenotyped for 23 flowering phenology traits and 4 floral agronomic traits over 3 years. Genotyping by sequencing (GBS) was used to obtain a large number of genome-wide single-nucleotide polymorphisms (SNPs) (107 050) for the panel genotypes, and 1047 candidate genes were identified by association mapping. Eighty-two related genes were observed during at least 2 years for flowering, and seven SNPs repeatedly identified for multiple flowering phenology traits over multiple years were highly significantly associated with five genes known to regulate flowering time. We validated the temporal expression profiles of these candidate genes and highlighted their possible roles in the regulation of flower bud differentiation and flowering time in tree peony. This study shows that GWAS based on GBS can be used to identify the genetic determinants of complex traits in tree peony. The results expand our understanding of flowering time control in perennial woody plants. Identification of markers closely related to these flowering phenology traits can be used in tree peony breeding programs for important agronomic traits.

Comparative investigation on heterotrophic denitrification driven by different biodegradable polymers for nitrate removal in mariculture wastewater: Organic carbon release, denitrification performance, and microbial community.

Heterotrophic denitrification is widely studied to purify freshwater wastewater, but its application to seawater wastewater is rarely reported. In this study, two types of agricultural wastes and two types of synthetic polymers were selected as solid carbon sources in denitrification process to explore their effects on the purification capacity of low-C/N marine recirculating aquaculture wastewater (NO3 --N 30 mg/L, salinity 32‰). The surface properties of reed straw (RS), corn cob (CC), polycaprolactone (PCL) and poly3-hydroxybutyrate-hydroxypropionate (PHBV) were evaluated by Brunauer-Emmett-Teller, Scanning electron microscope and Fourier-transform infrared spectroscopy. Short-chain fatty acids, dissolved organic carbon (DOC), and chemical oxygen demand (COD) equivalents were used to analyze the carbon release capacity. Results showed that agricultural waste had higher carbon release capacity than PCL and PHBV. The cumulative DOC and COD of agricultural waste were 0.56-12.65 and 1.15-18.75 mg/g, respectively, while those for synthetic polymers were 0.07-1.473 and 0.045-1.425 mg/g, respectively. The removal efficiency of nitrate nitrogen (NO3 --N) was CC 70.80%, PCL 53.64%, RS 42.51%, and PHBV 41.35%. Microbial community analysis showed that Proteobacteria and Firmicutes were the most abundant phyla in agricultural wastes and biodegradable natural or synthetic polymers. Quantitative real-time PCR indicated the conversion from nitrate to nitrogen was achieved in all four carbon source systems, and all six genes had the highest copy number in CC. The contents of medium nitrate reductase, nitrite reductase and nitrous oxide reductase genes in agricultural wastes were higher than those in synthetic polymers. In summary, CC is an ideal carbon source for denitrification technology to purify low C/N recirculating mariculture wastewater.

Combined genome-wide association studies and expression quantitative trait locus analysis uncovers a genetic regulatory network of floral organ number in a tree peony (Paeonia suffruticosa Andrews) breeding population.

Great progress has been made in our understanding of floral organ identity determination and its regulatory network in many species; however, the quantitative genetic basis of floral organ number variation is far less well understood for species-specific traits from the perspective of population variation. Here, using a tree peony (Paeonia suffruticosa Andrews, Paeoniaceae) cultivar population as a model, the phenotypic polymorphism and genetic variation based on genome-wide association studies (GWAS) and expression quantitative trait locus (eQTL) analysis were analyzed. Based on 24 phenotypic traits of 271 representative cultivars, the transcript profiles of 119 cultivars were obtained, which indicated abundant genetic variation in tree peony. In total, 86 GWAS-related cis-eQTLs and 3188 trans-eQTL gene pairs were found to be associated with the numbers of petals, stamens, and carpels. In addition, 19 floral organ number-related hub genes with 121 cis-eQTLs were obtained by weighted gene co-expression network analysis, among which five hub genes belonging to the ABCE genes of the MADS-box family and their spatial-temporal co-expression and regulatory network were constructed. These results not only help our understanding of the genetic basis of floral organ number variation during domestication, but also pave the way to studying the quantitative genetics and evolution of flower organ number and their regulatory network within populations.

Characterization of PsmiR319 during flower development in early- and late-flowering tree peonies cultivars.

The flowering period is the most important ornamental trait of tree peony, while industrial development of tree peony has been limited by short flowering period. miR319 plays an important regulatory role in plant flowering. In the current study, the expression characteristics and evolution of PsmiR319 in tree peony flowering was explored using 'Feng Dan' and 'Lian He', which are early-flowering and late-flowering varieties of tree peony, respectively. The structure, evolution, and target(s) of PsmiR319 were analyzed by bioinformatics. Evolution analysis showed that pre-PsmiR319 was distributed in 41 plant species, among which the length of the precursor sequence exhibited marked differences (between 52 and 308 bp). Pre-PsmiR319 of tree peony was located close to the corresponding sequences of Linum usitatissimum and Picea abies in the phylogenetic tree, and in addition, could form a typical hairpin structure including a mature body with a length of 20 bp located on the 3p arm and part of the loop sequence. The mature sequence of miR319 was highly conserved among different species. Target genes of PsmiR319 include MYB-related transcription factor in tree peony. Expression of PsmiR319, assayed by qRT-PCR, differed between 'Feng Dan' and 'Lian He' during different flower development periods. PsmiR319 and its target gene showed a negative expression regulation relationship during the periods of CE (color exposure), BS (blooming stage), IF (initial flowering), and HO (half opening) in the early-flowering 'Feng Dan', and the same in FB (Full blooming) periods of late-flowering 'Lian He'. Findings from this study provide a reference for further investigation into the mechanism of miR319 in the development of different varieties of tree peony.

Fatigue Fracture Analysis on 2524 Aluminum Alloy with the Influence of Creep-Aging Forming Processes.

The different creep-aging forming processes of 2524 aluminum alloy were taken as the research object, and the effects of creep-aging temperature and creep stress on the fatigue-crack propagation properties of the alloy were studied. The research results showed the following under the same sintering time of 9 h, at creep-aging temperatures of 100 °C, 130 °C, 160 °C, and 180 °C, respectively, with an increase in creep-aging temperature: the fatigue-crack propagation rate was promoted, the spacing of fatigue striations increased, and the sizes of dimples decreased while the number was enlarged; this proves that the fatigue property of the alloy was weakened. Compared with the specimens with creep deformation radii of 1000 mm and 1500 mm, the creep deformation stress was the smallest when the forming radius was 1800 mm, with a higher threshold value of fatigue-crack growth in the near-threshold region of fatigue-crack propagation (ΔK ≤ 8 MPa·m1/2). Under the same fatigue cycle, the specimens under the action of larger creep stress endured a longer fatigue stable-propagation time and a faster fracture speed. Comparing the effect of creep-aging temperature and creep stress, the creep-aging temperature plays a dominant role in the fatigue-crack propagation of creep-aged 2524 aluminum alloy.

Integrated analysis of miRNAome transcriptome and degradome reveals miRNA-target modules governing floral florescence development and senescence across early- and late-flowering genotypes in tree peony.

As a candidate national flower of China, tree peony has extremely high ornamental, medicinal and oil value. However, the short florescence and rarity of early-flowering and late-flowering varieties restrict further improvement of the economic value of tree peony. Specific miRNAs and their target genes engaged in tree peony floral florescence, development and senescence remain unknown. This report presents the integrated analysis of the miRNAome, transcriptome and degradome of tree peony petals collected from blooming, initial flowering, full blooming and decay stages in early-flowering variety Paeonia ostii 'Fengdan', an early-flowering mutant line of Paeonia ostii 'Fengdan' and late-flowering variety Paeonia suffruticosa 'Lianhe'. Transcriptome analysis revealed a transcript ('psu.G.00014095') which was annotated as a xyloglucan endotransglycosylase/hydrolase precursor XTH-25 and found to be differentially expressed across flower developmental stages in Paeonia ostii 'Fengdan' and Paeonia suffruticosa 'Lianhe'. The miRNA-mRNA modules were presented significant enrichment in various pathways such as plant hormone signal transduction, indole alkaloid biosynthesis, arachidonic acid metabolism, folate biosynthesis, fatty acid elongation, and the MAPK signaling pathway. Multiple miRNA-mRNA-TF modules demonstrated the potential functions of MYB-related, bHLH, Trihelix, NAC, GRAS and HD-ZIP TF families in floral florescence, development, and senescence of tree peony. Comparative spatio-temporal expression investigation of eight floral-favored miRNA-target modules suggested that transcript 'psu.T.00024044' and microRNA mtr-miR166g-5p are involved in the floral florescence, development and senescence associated agronomic traits of tree peony. The results might accelerate the understanding of the potential regulation mechanism in regards to floral florescence, development and abscission, and supply guidance for tree peony breeding of varieties with later and longer florescence characteristics.

Evaluation of a whole process management model based on an information system for cancer patients with pain: A prospective nonrandomized controlled study.

Objective: The aim of this study was to evaluate the effects of whole process management model interventions based on information system benefits reported by patients with cancer pain. Methods: We performed a quantitative, prospective nonrandomized controlled design from June to October 2020. A total of 124 cancer patients with pain were enrolled. Patients in the experimental group received a whole process management model intervention based on an information system compared to the control group who received routine cancer pain management. Data were collected at baseline and after a four-week follow-up, acting as a test-retest control. The primary outcome was pain management quality, which was measured using the American Pain Society Patient Outcome Questionnaire-Chinese version (APS-POQ-C). Secondary outcomes were patient-related attitudinal barriers and analgesic adherence. The Barrier Questionnaire (BQ) and a single-item questionnaire were used. Chi-square tests were used to compare the pain intensity and analgesic adherence, independent sample t-test and Mann-Whitney U test were performed to test the differences in the pain management quality and patient-related attitudinal barriers between control and experimental groups. Results: Baseline characteristics and outcomes of the participants did not differ significantly (P â€‹> â€‹0.05). Primary outcomes were changes in four aspect of the quality of pain management (APS-POQ-C) between the two groups (P â€‹< â€‹0.05). Patients in the whole process management group reported significantly better pain control and perception of care than the control group. With respect to secondary endpoints, a significant difference in favor of the experimental group was found for barriers (P â€‹< â€‹0.05) and medication adherence (60.0% vs. 40.0%; P â€‹< â€‹0.05) after the interventions. Conclusions: The whole process management of patients with cancer pain effectively improves patient-reported quality of pain management, reduces patient-perceived barriers, enhances patient adherence to analgesic drugs and is worthy of clinical application.

Draft genome of the famous ornamental plant Paeonia suffruticosa.

Tree peony (Paeonia Sect. Moutan) is a famous ornamental plant, with huge historical, cultural, and economic significance worldwide. In this study, we reported the ~13.79 Gb draft genome of a wide-grown Paeonia suffruticosa cultivar "Luo shen xiao chun," representing the largest sequenced genome in dicots to date. Phylogenetic analyses based on genome sequences demonstrated that P. suffruticosa was placed as sister to Vitales, and they together formed a clade that was sister to Rosids, weakly supporting a relationship of ((Saxifragales and Vitales) and Rosids). The identification and expression analysis of MADS-box genes based on the genome assembly and de novo transcriptome assembly of P. suffruticosa revealed that the function of C class genes was restricted in flower development, which might be responsible for the stamen petalody in tree peony cultivars. Overall, the first sequenced genome in the family Paeoniaceae provides an important resource for the origin, domestication, and evolutionary study as well as cultivar breeding in tree peony.
