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 explore the effect of the treadmill exercise intervention on the behavior function and the concentration of dopamine in the striatum of the rat model of Parkinson's disease (PD).Methods Healthy male Sprague-Dawley rats were randomly divided into a sham operation quiet (Control) group,sham-operation+Exercise (Control + Ex) group,6-hydroxydopamine (6-OHDA) quiet (PD) group,and 6-OHDA+Exercise (PD + Ex) group.PD and PD + Ex groups were injected 6-OH-DA into the right medial forebrain bundle to establish the unilateral PD rat model,while the sham operation groups were injected the same amount of physiological saline at the same site.On the 7th days after modeling,the rats were subcutaneously injected Apo morphine for rotational behavior test to exclude those not meeting the requirements for the PD model.One week after the operation,the exercise group started treadmill training at the speed of 11 m/min,30 min/day and 5 days/week,for a total of four weeks.The locomotor activity of PD rats was evaluated using the open field test.The DA concentration in striatum was detected using micro dialysis high performance liquid chromatography and electrochemistry.The expression of tyrosine hydroxylase positive fiber in the striatum was assessed using the immunohistochemistry.Results Compared with the Control group,significant decrease was observed in the moving distance of PD and PD + Ex groups (P＜0.01),while significant increase was found of PD + Ex group compared with PD group after 3 and 4weeks of training (P＜0.01).Compared with the Control group,DA concentration in the striatal decreased significantly in PD and PD + Ex groups,but that of PD + Ex group increased significantly after 3 and 4weeks' training compared with the PD group (P＜0.01).Conclusion There is a highly positive correlation between the total moving distance and the DA concentration in the striatum of PD rats.The moving distance and the DA concentration both have changed "sequentially" with the prolongation of 6-OHDA and exercise intervention.The exercise intervention can reduce the DA loss of the striatum and improve the locomotor function of PD rats.It is presumed that the mechanism may be related to the neuroprotective effect of exercise,which can reduce the damage of 6-OHDA neurotoxin to DA neurons and promote their survival.

Objective To translate The Pressure Ulcer Risk Primary or Secondary Evaluation Tool (PURPOSE-T) into Chinese,and assess its reliability and validity in Chinese hospitalized patients. Methods The original PURPOSE-T was translated into Chinese and back translated and modified for cultural adaptation according to guidelines.The reliability and validity of the Chinese version of PURPOSE-T were tested in 230 hospitalized patients. Results The Chinese version of PURPOSE-T consists of three parts and contains 25 entries. The inter-rater consistency Kappa coefficient was 0.798, the weighted Kappa coefficient was 0.843. The evaluation results were compared with binary variables with a Kappa coefficient of 0.745. The test-retest reliability Kappa coefficient and the weighted Kappa coefficient were 0.863 and 0.892. Two classified assessment Kappa coefficient was 0.857. The item content validity index ranged from 0.83 to 1.00, and the scale content validity index was 0.98. The phi correlation coefficient of PURPOSE-T and Braden scale was 0.781; the phi correlation coefficient of Waterlow Scale evaluation result was 0.777. The correlation coefficient between Chinese PURPOSE-T items and Braden scale items ranged from 0.605 to 0.877 (P<0.01), and the Waterlow Scale items ranged from 0.599 to 0.887 (P<0.01). Conclusions The Chinese version of PURPOSE-T appears to possess adequate validity, test-retest reliability and internal consistency. The newly translated Chinese version of PURPOSE-T may be used to assess the risk of pressure injury in inpatients in China.

NESCA, a newly discovered signaling adapter protein in the NGF-pathway, contains a RUN domain at its N-terminus. Here we report the crystal structure of the NESCA RUN domain determined at 2.0-Å resolution. The overall fold of the NESCA RUN domain comprises nine helices, resembling the RUN domain of RPIPx and the RUN1 domain of Rab6IP1. However, compared to the other RUN domains, the RUN domain of NESCA has significantly different surface electrostatic distributions at the putative GTPase-interacting interface. We demonstrate that the RUN domain of NESCA can bind H-Ras, a downstream signaling molecule of TrkA, with high affinity. Moreover, NESCA RUN can directly interact with TrkA. These results provide new insights into how NESCA participates in the NGF-TrkA signaling pathway.

In recent years,with the rapid development of the Next Generation Sequencing,the tumor heterogeneity has attracted widespread attention.It has been clear that heterogeneity in the same patient includes inter-tumor heterogeneity and intra-tumor heterogeneity.The former exists between different tumor lesions,such as primary tumor and metastatic tumor,and the latter occurs in different cancer cells.Tumor heterogeneity represents the ongoing challenge in the field of cancer treatment and brings great difficulty for the precision medicine.Therefore,it is possible to achieve accurate diagnosis and therapy for tumor patients by detecting the subclone of tumors and adjusting the treatment plan in time.

Objective·To analyze the differences and classify hypertrophic cardiomyopathy(HCM)patients and healthy controls(HC)using short-axis cine cardiac magnetic resonance(CMR)images-derived radiomics features.Methods·One hundred HCM subjects were included,and fifty HC were randomly selected at 2∶1 ratio during January 2018 to December 2021 in the Department of Cardiology,Renji Hospital,Shanghai Jiao Tong University School of Medicine.The CMR examinations were performed by experienced radiologists on these subjects.CVI 42 post-processing software was used to obtain left ventricular morphology and function measurements,including left ventricular ejection fraction(LVEF),left ventricular end-diastolic volume(LVEDV)and left ventricular end-diastolic mass(LVEDM).The 3D radiomic features of the end-diastolic myocardial region were extracted from short-axis images CMR cine.The distribution of the radiomic features in the two groups was analysed and machine learning models were constructed to classify the two groups.Results·One hundred and seven 3D radiomic features were selected and extracted.After exclusion of highly correlated features,least absolute shrinkage and selection operator(LASSO)was used,and a 5-fold cross-validation was performed.There were still 11 characteristics with non-zero coefficients.The K-best method was used to decide the top 8 features for subsequent analysis.Among them,four features were significantly different between the two groups(all P<0.05).Support vector machine(SVM)and random forest(RF)models were constructed to discriminate the two groups.The results showed that the maximum area under the curve(AUC)for the single-feature model(first order grayscale:entropy)was 0.833(95%CI 0.685?0.968)and the maximum accuracy for the multi-feature model was 83.3%with an AUC of 0.882(95%CI 0.705?0.980).Conclusion·There are significant differences in both left ventricular function and left ventricular morphology between HCM and HC.The 3D myocardial radiomic features of the two groups are also significantly different.Although single feature is able to distinguish the two groups,the combination of multi-features show better classification performance.

Objective:To investigate the safety of minimally invasive liver resection for resectable hepatocellular carcinoma (HCC) complicated with portal hypertension.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 807 patients with resectable HCC who underwent minimally invasive liver resection in 8 medical centers, including Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine et al, from June 2011 to November 2022 were collected. There were 670 males and 137 females, aged 58(50,66)years. Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.

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.
