Abstract
The programmed self-assembly of patchy nanoparticles (NPs) through a bottom-up approach is an efficient strategy for producing highly organized materials with a predetermined architecture. Herein, we report the preparation of di- and trivalent silica NPs with polystyrene (PS)/poly(4-vinylbenzyl azide) (PVBA) patches and assemble them in a THF mixture by lowering the solvent quality. Silica-PS/PVBA colloidal hybrid clusters were synthesized through the seeded growth emulsion copolymerization of styrene and 4-vinylbenzyl azide (VBA) in varying ratios. Subsequently, macromolecules on silica NPs originating from the copolymerization of growing PS or PVBA chains with the surface-grafted MMS compatibilizer are engineered by fine-tuning of polymer compositions or adjustment of solvent qualities. Moreover, multistage silica regrowth of tripod and tetrapod allowed a fine control of the patch-to-particle size ratio ranging from 0.69 to 1.54. Intriguingly, patchy silica NPs (1-, 2-, 3-PSNs) rather than hybrid clusters are successfully used as templates for multistep regrowth experiments, leading to the formation of silica NPs with a new morphology and size controllable PVBA/PS patches. Last but not least, combined with mesoscale dynamics simulations, the self-assembly kinetics of 2-PSN and 3-PSN into linear colloidal polymers and honeycomb-like lattices are studied. This work paves a new avenue for constructing colloidal polymers with a well-defined sequence and colloidal crystals with a predetermined architecture.

Abstract
Background The objective of this study is to analyze the characteristics of pediatric echocardiography clinical trials registered in ClinicalTrials.gov. Methods A data set including pediatric echocardiography clinical trials was downloaded from ClinicalTrials.gov until May 13, 2022. We searched the PubMed, Medline, Google Scholar, and Embase databases to extract publication data. Pediatric echocardiography trial characteristics, application areas, and publication status were described. The secondary objectives were to evaluate factors associated with trial publication. Results We identified 410 pediatric echocardiography reporting definite age, of which 246 were interventional and 146 were observational. Drug interventions were the most commonly studied (32.9%). The most applied area of pediatric echocardiography was congenital heart disease, followed by hemodynamics of preterm or neonatal infants, cardiomyopathy, inflammatory heart disease, pulmonary hypertension, and cardio-oncology. According to the primary completion data, 54.9% of the trials were completed before August 2020. 34.2% of the trials had been published within 24 months. Union countries and quadruple masking were more likely to be published. Conclusion Echocardiography is rapidly evolving in pediatric clinical applications, including anatomic imaging and functional imaging. Novel speckle tracking techniques have also been pivotal in the assessment of cancer therapeutics-related cardiac dysfunction. A small number of clinical trials in pediatric echocardiography are published in a timely fashion. Concerted efforts are needed to promote trial transparency.

Abstract
STUDY BACKGROUND OBJECTIVES Cancer poses a significant health concern as it is incurable. Every year, research on how to treat and eradicate this chronic condition is done. This systematic review will unmask the recent developments concerning highly active 1C metabolism with regard to cancer diagnosis, treatment, and drug resistance. The significance of this study is rolling out evidence-based evidence on the importance of one-carbon metabolism in cancer diagnosis and treatment. METHODS Eight randomized controlled trials (RCTs) were reviewed from five electronic databases - EMBASE, Scopus Review, Google Scholar, Web of Science, and PubMed. Outcomes from the eight studies were analyzed to paint a picture of the topic in question. While the Preferred Reporting Items for Systematic Reviews and Meta-Analysis' (PRISMA) protocol guided the initial literature search, The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach informed quality assessments of the eligible studies. CONCLUSION Since its emergence in the 1980s, 1C metabolism has been investigated and broadened to capture essential aspects of cancer treatment, diagnosis, and drug resistance. The review found that metabolites like folic acid could be used to detect different types of cancer. The metabolic pathways could induce tumorigenesis and DNA methylation, hence drug resistance.

Abstract
Objective: The perspective of real-world study is especially relevant to newborns, enabling dosage regimen optimization and regulatory approval of medications for use in newborns. The aim of the present study was to conduct a pharmacokinetic analysis of cefotaxime and evaluate the dosage used in newborns with early-onset sepsis (EOS) using real-world data in order to support the rational use in the clinical practice. Methods: This prospective, open-label study was performed in newborns with EOS. A developmental pharmacokinetic-pharmacodynamic model of cefotaxime in EOS patients was established based on an opportunistic sampling method. Then, clinical evaluation of cefotaxime was conducted in newborns with EOS using real-world data. Results: A one-compartment model with first-order elimination was developed, using 101 cefotaxime concentrations derived from 51 neonates (30.1–41.3°C weeks postmenstrual age), combining current weight and postnatal age. The pharmacokinetic-pharmacodynamic target was defined as the free cefotaxime concentration above MIC during 70% of the dosing interval (70% fT > MIC), and 100% of neonates receiving the dose of 50 mg/kg, BID attained the target evaluated using the model. Additionally, only two newborns had adverse reactions possibly related to cefotaxime treatment, including diarrhea and feeding intolerance. Conclusion: This prospective real-world study demonstrated that cefotaxime (50 mg/kg, BID) had a favorable efficacy and an accepted safety profile for neonates with EOS.

Abstract
The objective of this study was to investigate whether MTNR1B gene variants influence repaglinide response in Chinese patients with newly diagnosed type 2 diabetes mellitus (T2DM). A total of 300 patients with T2DM and 200 control subjects were enrolled to identify MTNR1B rs10830963 and rs1387153 genotypes by real-time polymerase chain reaction (PCR), with subsequent high-resolution melting (HRM) analysis. Ninety-five patients with newly diagnosed T2DM were randomly selected to undergo 8 weeks of repaglinide treatment (3 mg/day). After 8-week repaglinide monotherapy, patients with at least one G allele of MTNR1B rs10830963 showed a smaller decrease in fasting plasma glucose (FPG) (P = 0.031) and a smaller increase in homeostasis model assessment for beta cell function (HOMA-B) (P = 0.002) levels than those with the CC genotype did. The T allele carriers at rs1387153 exhibited a smaller decrease in FPG (P = 0.007) and smaller increases in postprandial serum insulin (PINS) (P = 0.016) and HOMA-B (P < 0.001) levels compared to individuals with the CC genotype. These data suggest that the MTNR1B rs10830963 and rs1387153 polymorphisms are associated with repaglinide monotherapy efficacy in Chinese patients with T2DM.

Abstract
The aim of this study was to probe the influence of continuous nursing intervention on recovery of diabetic patients. From October 2016 to June 2017, 80 diabetic patients who received treatment in our hospital were selected and randomly divided into an intervention group and a control group. The intervention group received continuous nursing care including indirect follow-up, health education and home visit. The self-care ability and blood sugar of the two groups were compared three months later. The score of self-care ability in the intervention group was 89.64±1.64 and that in control group was 72.68±2.47, and a significant difference was observed (P less than 0.001). The fasting blood glucose level in the intervention group was 6.62±0.86 MMOL/L, and the 2-hour post-meal blood glucose level was 8.47±1.32 MMOL/L, which were both lower than those in the control group. Continuous nursing can help monitor the recovery of patients after discharge. It is helpful to improve the self-care ability of patients, control blood sugar level, and promote recovery. It is worth wide promotion.

Abstract
Several additives, including inorganic (NaCl) and organic salts (derivatives of benzoate), were added into aqueous solutions of a gemini cationic surfactant, 2-hydroxypropyl-1,3-bis (myristyldimethylammonium chloride) (abbreviated as 14-3(OH)-14(2Cl)). The mixed systems were investigated using rheological measurement, cryo-TEM and 1H NMR analysis. The results showed that addition of salts induced rich aggregate morphologies in the 14-3(OH)-14(2Cl)/salt systems. The influence of an inorganic salt on the viscoelasticity of 14-3(OH)-14(2Cl) solutions is much weaker than that of organic salts. Furthermore, the ability of three organic salts in enhancing the viscoelasticity of 14-3(OH)-14(2Cl) solutions is in the order sodium m-hydroxybenzoate > sodium o-hydroxybenzoate > sodium p-hydroxybenzoate. The different roles of these organic salt isomers arise from the different types of hydrogen bonding formed between 14-3(OH)-14(2Cl) and the organic counter ions.

Abstract
Quality of life (QOL) throughout menopause has become an outcome variable requiring measurement in clinical care. Staff nurses can provide earlier nursing during the menopausal transition (MT) stage. The purpose of this study was to describe the changes of QOL in different stages of the MT according to The Stages of Reproductive Aging Workshop (STRAW) in Chinese women in community settings. Prospective longitudinal study design was used to analyze QOL of 327 community women age 30-65years old. They were followed up at 1-year. An instrument including the Chinese version of the Menopause-Specific Quality of Life Questionnaire was used to obtain data. A gradual decline in QOL was seen from premenopausal to menopausal transition (MT) and in postmenopausal women. Significant differences were observed in vasomotor, physical and sexual scores at baseline and follow-up (P<0.05). Significant differences in vasomotor scores were observed between baseline and follow-up for women in the premenopausal and Late MT stages (P<0.05). There were significant differences in psychosocial and physical scores between baseline and follow-up in the Late MT stage (P<0.05). Menopause might have a negative impact on QOL independent of age in community-based women in China. There seemed to be a potential model of the relationship of menopause status to change in QOL, but this needs supporting evidence from longer longitudinal studies.

Abstract
This study aimed to explore the diagnostic and prognostic values of contrast-enhanced ultrasound (CEUS) in breast cancer. Between September 2009 and October 2011, a total of 143 breast cancer patients and 161 healthy people were selected as case group and control group, respectively. After the identification of lesions by conventional ultrasound, all patients underwent CEUS. The CEUS images were analyzed, and time–intensity curves (TICs) were obtained. Hematoxylin–eosin and immunohistochemistry staining was performed on tissue specimens, according to which the expressions of estrogen receptor (ER), c-erb-B2, p53, and Ki-67 were measured. Multivariate logistic regression analysis was used to compare CEUS and TIC parameters between the two groups. Compared with the control group, cancer patients showed high enhancement, heterogeneous enhancement or defects in the central region, expansion of lesion diameter after enhancement and crab-like blur lesion edges. The peak intensity (PI), relative start time of enhancement, relative PI, and relative area under the curve in the case group were significantly higher than those in the control group. Logistic analysis showed that the uniformity of enhancement, expansion of lesion diameter, and relative PI were significant diagnostic parameters of breast cancer, with area under the curve being 0.798, 0.776, and 0.919, respectively. There were strong associations between CEUS characteristics and expressions of prognostic factors in breast cancer: the heterogeneous enhancement was common in c-erb-B2-positive tumors; the centripetal enhancement occurred more in ER-negative tumors; perforator vessels were often seen in tumors at high histological grade; perfusion defects were common in ER-negative, c-erb-B2-positive, and Ki-67-positive tumors. CEUS is a useful tool for the early diagnosis and prognosis of breast cancer.

Abstract
Next-generation sequencing provides large-scale sequencing data with relative ease and at a reasonable cost, making it possible to identify a large amount of SSR markers in a timely and cost-effective manner. On the basis of the transcriptome database of Sinonovacula constricta obtained by Illumina/Solexa pyrosequencing, 60 polymorphic SSR markers were developed and characterized in 30 individuals. The number of alleles per polymorphic locus ranged from 2 to 7 with an average of 3.75 alleles. The observed and expected heterozygosities varied from 0.050 to 1.000 and from 0.050 to 0.836, respectively. Nineteen loci significantly deviated from Hardy-Weinberg equilibrium (P < 0.01) after Bonferroni's correction for multiple tests. In addition, interspecific transferability revealed that 20 polymorphic loci in Solen linearis were first characterized in this study. To the best of our knowledge, this is the highest number of SSRs in S. constricta and the first report of cross-species amplification. These novel polymorphic SSR markers will be particularly useful for conservation genetics, evolutionary studies, genetic trait mapping, and marker assisted selection in the species.

Abstract
STUDY OBJECTIVE To investigate the associations of NOS1AP rs12742393 polymorphism with the risk of type 2 diabetes mellitus (T2DM) and repaglinide therapeutic efficacy in Chinese patients with T2DM. DESIGN Prospective case-control study. SETTING Academic medical center. PATIENTS A total of 300 patients with T2DM and 200 healthy volunteers were enrolled to identify NOS1AP rs12742393 genotypes using the polymerase chain reaction-restriction fragment length polymorphism assay. Eighty-four patients with various genotypes were randomly selected to receive oral repaglinide as a single-agent therapy (3 mg/day) for 8 weeks. MEASUREMENTS AND MAIN RESULTS Anthropometric measurements and fasting plasma glucose (FPG), postprandial plasma glucose, hemoglobin A1c , fasting serum insulin (FINS), postprandial serum insulin, homeostasis model assessment for insulin resistance (HOMA-IR), triglyceride, total cholesterol, low-density lipoprotein-cholesterol, and high-density lipoprotein-cholesterol tests were obtained before and after repaglinide treatment. The risk C allelic frequency of NOS1AP rs12742393 was higher in patients with T2DM than in healthy volunteers (p<0.001). Patients with T2DM and genotypes AA and AC at NOS1AP rs12742393 had a significant reduction in FPG (mmol/l) compared with those with genotype CC (p<0.01). Patients with CC homozygotes and AC heterozygotes had a greater increase in FINS (mU/l) than those with wild-type AA (p<0.05). In addition, the carriers of genotype CC at NOS1AP rs12742393 had higher differential values of HOMA-IR compared with genotypes AC and AA carriers (p<0.001). The effects of repaglinide treatment on FPG (p<0.01), FINS (p<0.05) and HOMA-IR (p<0.001) were reduced in patients with T2DM carrying the NOS1AP rs12742393 risk C allele compared with the AA genotype carriers. CONCLUSION The NOS1AP rs12742393 polymorphism is associated with therapeutic efficacy of repaglinide in Chinese T2DM patients.

Abstract
AIMS The present study was conducted to evaluate the psychometric properties of a newly adapted Chinese version of an instrument designed to measure structural empowerment among staff nurses. BACKGROUND Structural empowerment has been shown to be important to nurses in Western cultures, but its importance in China is unknown. METHODS A convenience sample of 650 staff nurses was selected from six hospitals in Harbin, China. After linguistic adaptation using the forward-backward translation method, the 19-item Conditions of Work Effectiveness Questionnaire-II (CWEQ-II-CV) was answered by participants. Content validity, Cronbach's alpha, item-to-total correlation and exploratory factor analysis were used to assess the reliability and validity of the translated instrument. RESULTS In the factor analysis, a six-factor solution was found to be reasonable with the sub-dimensions of structural empowerment that included support (three items), resources (three items), information (three items), opportunity (three items), formal power (three items) and informal power (four items). Cronbach's alpha coefficient for the total instrument was 0.92 and ranged from 0.68 to 0.86 in the six subscales. The item-to-total correlation coefficients ranged from 0.48 to 0.80. The findings also gave support for content validity. CONCLUSIONS Evidence was found to support the reliability and validity of the CWEQ-II-CV scale that measures the quality of the work environment for nurses from a structural empowerment perspective. IMPLICATIONS FOR NURSING MANAGEMENT The translated version of CWEQ-II-CV can provide an effective evaluation tool for structural empowerment in the Chinese nursing workplace.

Abstract
AIMS This study was conducted to adapt the Problem Areas in Psychological Empowerment Scale for use among staff nurses and to evaluate the psychometric properties. BACKGROUND Considering the importance of psychological aspects in the administration of nursing, there is a need for validated measurements in this area. Such tools make it possible to understand staff nurses as well as they serve as reliable measures when evaluating medical, psychological and educational interventions. DESIGN Instrument development. METHODS A convenience sample of 750 staff nurses was systematically selected from six hospitals in Harbin, China. Following the linguistic adaptation using the forward-backward translation method, the 12-item Psychological Empowerment Scale was answered by the selected staff nurses. Statistics covered exploratory factor analysis, content validity, Cronbach's alpha and item-to-total correlation. RESULTS In the factor analysis, a four-factor solution was found to be reasonable with the subdimensions psychological empowerment-related meaning problems (three items), competence problems (three items), self-determination (three items) and impact problems (three items). Cronbach's alpha coefficient for the total score was 0.85 and varied between 0.82-0.89 in the four subscales. The item-to-total correlation coefficient was 0.40, and items were excluded with item-to-total correlation coefficient of lower than 0.40. The findings also gave support for the content validity. CONCLUSIONS The Chinese version of the Problem Areas in Psychological Empowerment Scale seems to be reliable and valid outcome for measuring empowerment-related psychological response in staff nurses. RELEVANCE TO CLINICAL PRACTICE The Psychological Empowerment Scale can be used to evaluate staff nurses' empowerment-related psychological response in clinical.

Abstract
OBJECTIVE To study the habitat characteristics for the growth of Atractylodes lancea. METHOD The leading factors for the growth of A. lancea are determined after stepwise regression, and the limiting factor are determined by field study, literature search,and weather records. The mean values of leading factors and the limiting factors of A. lancea for 30 years were applied to do spatial interpolation using IDIRIEIW softwares. An overlay was prerformed using data obtained in Mt. Maoshan and the general habitat of A. Iancea. RESULT It was found that precipitation is one of the dominant climate factors that affects the quality of A. lancea. High temperature was one of the limiting factor which influences the living of A. lancea. The best habitat was determined to be: annual mean temperature more than 15 degrees C, monthly mean minimum temperature between - 2- -1 degrees C, monthly mean maximum temperature about 32 degrees C, lowest tolerable temperature - 17- -15 degrees C, drought season 1 - 2 months, annual mean precipitation between 1000 - 1160 mm. CONCLUSION Mt. Maoshan was characterized by having high temperature, short drought season and adequate precipitation. The growth of A. Lancea is a result of environmental stress.
