Objective To investigate the related factors of early liver cancer recurrence associated with elevated fasting glucose levels after radical resection of liver cancer.Methods The retrospective cohort study was adopted.The clinical data of 145 patients with liver cancer who were admitted to the Nanfang Hospital of Southern Medical University from October 2009 to June 2013 werc collected.After radical resection of liver cancer, 111 patients with average level of fasting blood glucose (FBG) ＜ 6.1 mmol/L and 34 patients with level of FBG ≥ 6.1 mmol/L were divided into the normal group and the hyperglycemic group, respectively.The blood glucose levels of patients during the period of hospital stay and follow-up were observed.The status of early recurrence and risk factors affecting recurrence in the 2 groups were analyzed.Follow-up of outpatient examination was applied to patients up to July 1, 2015 with the first recurrence as the end point.Patients had reexaminations once every month within postoperative month 6 and once every 3 months after 6 months.The general information [gender, age, FBG, underlying hepatopathy, preoperative AFP, alanine transaminase (ALT), aspartate aminotransferase (AST), Child-Pugh stage, Barcelona Clinic Liver Cancer (BCLC) stage, history of alcohol drinking], surgical data (surgical method, operation time, number of blood transfusion, volume of intraoperative blood loss), pathological data (histopathological differentiation, number of tumor nodules, diameter of maximal tumor, liver cirrhosis) and follow-up data (postoperative AFP, imaging findings, recurrence time, preventive chemotherapy) were collected.Measurement data with normal distribution were presented as-x ± s and analyzed by the t test.Measurement data with skewed distribution were presented as M (range) and analyzed by the non-parametric test.Count data were analyzed using the chi-square test.With the first recurrence as the end point, the tumor-free survival rate was drawn using the Kaplan-Meier method, and the comparison was analyzed by the logrank test.The risk factors affecting recurrence were analyzed using the Kaplan-Meier method for proportional hazards assumption test firstly, and then eligible factors were done using Log-rank test in the univariate analysis.The multivariate analysis was done using the COX model.Results The postoperative 1-, 2-year overall recurrence rates of liver cancer were 28.3％ (41/145) and 45.5％ (66/145).And 1-, 2-year recurrence rates of liver cancer were 21.6％ (24/111) and 36.9％ (41/111) in the normal group and 50.0％ (17/34) and 73.5％ (25/34) in the hyperglycemic group, respectively, showing significant differences between the 2 groups (x2=10.335, 14.053, P ＜ 0.05).The univariate analysis showed that FBG, Child-Pugh stage, volume of intraoperative blood transfusion and postoperative AFP were risk factors affecting tumor-free survival rate after radical resection of liver cancer (x2 =17.591,6.492, 10.690,12.820, P ＜ 0.05).The tumor-free survival rates at postoperative month 24 in the normal group and hyperglycemic group were 63.1％ and 26.5％ respectively, showing significant difference between the 2 groups (x2=17.591, P ＜ 0.05).The results of multivariate analysis showed that level of FBG ≥6.1 mmol/L, volume of intraoperative blood transfusion ＞ 200 mL and postoperative level of AFP ＞ 8.1 pg/L were independent risk factors affecting tumor-free survival rate after radical resection of liver cancer (RR =2.542, 2.028, 2.724, 95 ％ condifence interval : 1.529-4.225,1.183-3.479,1.635-4.538, P ＜ 0.05).Conclusions Elevated FBG level has a stimulative effect on early recurrence of tumor after radical resection of liver cancer.As a result, monitoring and controlling of blood glucose after operation is helpful in decreasing the early recurrence rate of patients with liver cancer.

Objective To validate the efficiency of 27-plex single nucleotide polymorphism (SNP) multiplex system for ancestry inference. Methods The 27-plex SNP system was validated for its sensitivity and species specificity. A total of 533 samples were collected from African, Southern Chinese Han, China's ethic minorities (Yi, Hui, Miao, Tibet, and Uygur), European, Central Asian, Western Asian, Southern Asian, Southeast Asian and South American populations for clustering analysis of the genotypes by citing 3 representative continental ancestral groups [East Asia (CHB), Europe (CEU), and Africa (YRI)] from HapMap database. Results The system sensitivity is 0.125 ng. Twenty and six genotypes were detected in chimpanzee and monkeys, respectively. Except in rs10496971, no more products were found in other animals. The system was capable of differentiating intercontinental populations but not of distinguishing between East Asian and Southeast Asian population or between Southern Chinese Han population and Chinese Ethnic populations (Hui, Miao, Yi and Tibet). This system achieved a 100%accuracy for intercontinental population source inference for 46 blind test samples. Conclusion 27-plex SNPs multiplex system has a high sensitivity and species specificity and can correctly differentiate the ancestry origins of individuals from African, European and East Asian for criminal case investigation. But this system is not capable of distinguishing subpopulation groups and more specific ancestry-informative markers are needed to improve its recognition of Southeast Asian and Chinese ethnic populations.

Objective To systematically evaluate and integrate qualitative research related to the psychological experiences and perceptions of body image in bum patients.The goal is to provide a reference basis for developing targeted intervention measures in clinical practice.Methods The databases of CNKI,Wanfang,VIP Chinese Science and Technology Periodical Database,China Biomedical Literature Service System,PubMed,Web of Science,Embase,Medline,Cochrane Library,PsycINFO,and Scopus were applied in our study.Relevant qualitative studies on the body image experience of burn patients from the establishment of the databases until December 2022 were collected.The quality of the included literature was assessed using the 2016 edition of the Joanna Briggs Institute(JBI)Centre for Evidence-based Health Care in Australia,and the results of the literature were integrated using aggregative integration.Results A total of 12 pieces of literature were included,from which 40 research findings were extracted.These findings were ultimately summarized into 4 integrated results:diverse traumatic perceptions of body image changes faced by burn patients,active exploration and negative coping strategies towards body image changes faced by burn patients,emotional information needs and post-traumatic growth.Conclusion Burn patients experience various body image issues that hinder their return to normal life.It is crucial for healthcare professionals to timely attend to the physical and mental well-being of the patients,identify body image disorders,assist families in meeting emotional needs,support patients in self-adjustment,and promote positive outcomes.

Objective:To construct an evaluation indicator system for the effectiveness of health education in patients with implanted ports, and to provide a theoretical basis for assessing the outcomes of health education in this patient population.Methods:Based on the Knowledge-Attitude-Practice (KAP) theory, a preliminary framework for the health education indicator system was constructed through literature review and semi-structured interviews. The Delphi method was employed to revise and refine the indices, and the Analytic Hierarchy Process (AHP) was used to calculate the weight of each indicator.Results:The effective response rates for the two rounds of Delphi consultation questionnaires were 100.00% (22/22) and 90.91% (20/22), respectively. The expert authority coefficients were 0.925 and 0.918, respectively. The coordination coefficients of expert opinions for the first and second-level indicators in the second round of expert consultation were 0.194 and 0.333, respectively. The final evaluation indicator system for health education effectiveness in patients with implanted ports included 3 first-level indicators and 36 second-level indicators.Conclusions:The constructed evaluation indicator system for health education effectiveness in patients with implanted ports is scientific and reliable and facilitates the accurate assessment of health education outcomes in this patient population.

Objective To characterize the distribution and assess the exposure to phthalic acid esters （PAEs） in the indoor dust of Shanghai City. Methods Samples were collected from 33 sampling sites， including homes， hotels， offices and public places， in Shanghai in 2018， 2019， and 2020. The samples were pretreated by 100 sieves， extracted and concentrated， and then analyzed by gas chromatography-mass spectrometry in selected ion mode （SIM）. Results Results on the characteristics of PAEs in indoor dust in different places showed that concentrations of PAEs were in a range of <0.01-2 464 mg·kg^-1.The average concentration of 16 PAEs was 613 mg·kg^-1. Bis（2-ethylhexyl） phthalate （DEHP）， di-iso-butyl phthalate （DiBP）， di-n-butyl phthalate （DBP） and di-n-octyl phthalate （DnOP） were the main components of PAEs in indoor dust， accounting for approximately 99.5% of 16 PAEs. The intake of DEHP， DBP， DEP and BBP was lower than the tolerable daily intake （TDI） and reference doses （RfD） set by EU CSTEE and U.S. EPA. Conclusion Average daily dose （ADD） via indoor dust is estimated， and the order of intake through different pathways is hand-oral intake>skin contact>respiratory inhalation. Exposure risk of PAEs in children is greater than that in adults.
