RESUMO
Phloretin, a natural component of many fruits, exhibits anti-virulence effects and provides a new alternative to counter bacterial infection. The aim of this study was to determine the effect of subinhibitory concentrations of phloretin on the virulence of Salmonella typhimurium. At concentrations where growth of Salmonella was not inhibited, phloretin significantly inhibited bacteria biofilm formation and motility. Subinhibitory concentrations of phloretin repressed eight genes involved in the Salmonella pathogenicity island 1 and 3 genes involved in flagella production. Furthermore, subinhibitory concentrations of phloretin inhibited the adhesion and invasion of Salmonella in IEC-6 cells and reduced the LDH levels of S. typhimurium-infected IEC-6 cells. Additionally, phloretin significantly decreased the cecum bacterial loads of the mice infected with live S. typhimurium containing subinhibitory concentrations of phloretin by gavage. These results suggested that subinhibitory concentrations of phloretin attenuate the virulence of S. typhimurium and protect against S. typhimurium infection.

A genetic etiology for autism spectrum disorders (ASDs) was first suggested from twin studies reported in the 1970s. The identification of gene mutations in syndromic ASDs provided evidence to support a genetic cause of ASDs. More recently, genome-wide copy number variant and sequence analyses have uncovered a list of rare and highly penetrant copy number variants (CNVs) or single nucleotide variants (SNVs) associated with ASDs, which has strengthened the claim of a genetic etiology for ASDs. Findings from research studies in the genetics of ASD now support an important role for molecular diagnostics in the clinical genetics evaluation of ASDs. Various molecular diagnostic assays including single gene tests, targeted multiple gene panels and copy number analysis should all be considered in the clinical genetics evaluation of ASDs. Whole exome sequencing could also be considered in selected clinical cases. However, the challenge that remains is to determine the causal role of genetic variants identified through molecular testing. Variable expressivity, pleiotropic effects and incomplete penetrance associated with CNVs and SNVs also present significant challenges for genetic counseling and prenatal diagnosis.

Attention-deficit/Hyperactivity disorder(ADHD) is a common neurodevelopmental disorder among children. Traditional assessment methods generally rely on behavioral rating scales (BRS) performed by clinicians, and sometimes parents or teachers. However, BRS assessment is time consuming, and the subjective ratings may lead to bias for the evaluation. Therefore, the major purpose of this study was to develop a Virtual Reality (VR) classroom associated with an intelligent assessment model to assist clinicians for the diagnosis of ADHD. In this study, an immersive VR classroom embedded with sustained and selective attention tasks was developed in which visual, audio, and visual-audio hybrid distractions, were triggered while attention tasks were conducted. A clinical experiment with 37 ADHD and 31 healthy subjects was performed. Data from BRS was compared with VR task performance and analyzed by rank-sum tests and Pearson Correlation. Results showed that 23 features out of total 28 were related to distinguish the ADHD and non-ADHD children. Several features of task performance and neuro-behavioral measurements were also correlated with features of the BRSs. Additionally, the machine learning models incorporating task performance and neuro-behavior were used to classify ADHD and non-ADHD children. The mean accuracy for the repeated cross-validation reached to 83.2%, which demonstrated a great potential for our system to provide more help for clinicians on assessment of ADHD.

ObjectiveTo systematically review the evidences of impact of exercise rehabilitation and adapted physical activity on psychomotor skills, motor abilities, and motor development in children with spastic cerebral palsy (CP). MethodsRelevant literature was retrieved from PubMed, Embase, Web of Science and CNKI, from January, 2010 to June, 2023. The contents were coded using International Classification of Diseases, Eleventh Revision, and International Classification of Functioning, Disability and Health; and evidences were analyzed with theoretical framework and code of ICD-11 and ICF. ResultsA total of nine articles were included, from Denmark, South Korea, Australia, Saudi Arabia, Ghana, India and Japan, published from 2015 to 2022. The intervention programs primarily involved exercise rehabilitation (including physical therapy) and adapted physical activity. Exercise rehabilitation included upper limb strength training, lower limb strength training, balance and coordination training, gait training, functional aerobic exercise, stretching and flexibility exercises, flexibility training, muscle relaxation techniques; ten to 50 minutes a time, two to six times a week,with the intensity of low to high, for six to 20 weeks. Adapted physical activities mainly involved adapted running training, virtual games; 60 minutes a time, two to four times a week, with the intensity of medium to high, for six to twelve weeks. Interventions primarily took place in medical and rehabilitation institutions, schools, and home-based communities, with professionals including occupational physical therapists, university researchers, community health personnel and teachers. The outcomes were mainly reflected in four aspects: psychomotor skills, motor abilities, motor development, and quality of life and well-being. In terms of psychomotor skills, adolescents with CP mastered running techniques and knowledge, and enhanced their response to balance threats. In terms of motor abilities, adolescents with CP showed an increase in muscle strength, enhanced muscle endurance, and an expansion of muscle tone; improvements in gait functionality, walking ability, and gait symmetry; increases in walking endurance; improvements in standing function; and improvements in dynamic balance; as well as enhanced control over balance posture. In terms of motor development, there was a significant improvement in activities of daily living, participation levels in school and leisure activities during free time, and an expanded range of motion. In terms of quality of life and well-being, adolescents with CP showed significant enhancements in self-confidence and self-esteem, significant relief from (spastic) pain, and improvements in social well-being and acceptance. ConclusionThis systematic review has synthesized the evidences of benefits of exercise rehabilitation and adapted physical activity on the psychomotor skills, motor abilities and motor development of children and adolescents with spastic CP. In terms of psychomotor skills, exercise rehabilitation and adapted physical activity help to improve the cognitive and motor skills of adolescents with spastic CP. In terms of motor abilities, exercise rehabilitation and adapted physical activity can improve muscle-related functions, gait and walking abilities, as well as balance and coordination. In terms of motor development, exercise rehabilitation and adapted physical activity significantly enhance activities of daily living and the level of participation in leisure physical activities. Finally, exercise rehabilitation and adapted physical activity can increase energy and motivation, alleviate pain, and enhance social well-being and acceptance.
RESUMO
BACKGROUND: The 2014-2016 Ebola virus epidemic in West Africa was the largest outbreak of Ebola virus disease (EVD) in history. Clarifying the influence of other prevalent diseases such as human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) will help improve treatment and supportive care of patients with EVD. CASE PRESENTATION: We examined HIV and hepatitis C virus (HCV) antibody prevalence among suspected EVD cases from the Sierra Leone-China Friendship Biological Safety Laboratory during the epidemic in Sierra Leone. HIV and HCV antibodies were tested in 678 EVD-negative samples by enzyme-linked immunosorbent assay. A high HIV prevalence (17.6%) and low HCV prevalence (0.22%) were observed among the suspected cases. Notably, we found decreased HIV positive rates among the suspected cases over the course of the epidemic. This suggests a potentially beneficial effect of an improved public health system after assistance from the World Health Organization and other international aid organizations. CONCLUSIONS: This EVD epidemic had a considerable impact on the public health system and influenced the prevalence of HIV found among suspected cases in Sierra Leone, but also provided an opportunity to establish a better surveillance network for infectious diseases.

RESUMO
BackgroundSleep disorder can adversely affect human physical and mental health, with important implications for socioeconomic development. And higher vocational college students are subject to various pressures and stimuli exerted by academic studies, job seeking and family socioeconomic status, which may contribute to the onset insomnia symptom or sleep disorder. ObjectiveTo discuss the sleep status and influencing factors among higher vocational college students, and to provide references for improving their sleep status. MethodsIn January and February, 2022, a stratified random sampling method was utilized to enroll 3 300 students from five higher vocational colleges in Wenjiang district of Chengdu city. All the participants were assessed using Insomnia Severity Index (ISI), Patient Health Questionnaire Depression Scale-9 item (PHQ-9) and Generalized Anxiety Disorder Scale-7 (GAD-7). Pearson correlation analysis was conducted to test the correlation of ISI with PHQ-9 and GAD-7 scores, and the Logistic regression analysis was performed to identify the influencing factors of insomnia symptom in higher vocational college students. ResultInsomnia symptom was detected in 81.90% (2 497 / 3 300) of higher vocational college students. The detection rate of insomnia symptom among vocational college students yielded statistical difference in terms of gender, family socioeconomic status, being an only child or having siblings, degree of psychological pressure exerted by academic studies or job seeking, amount of hours spent on Internet per day, frequency of physical exercise, and the presence or absence of anxiety symptom and depression symptom (χ2=21.032, 22.172, 8.983, 75.939, 36.781, 32.350, 54.512, 86.561, P<0.01 or 0.05). Among higher vocational college students, ISI score was positively correlated with GAD-7 and PHQ-9 scores (r=0.620, 0.714, P<0.01), and GAD-7 score was positively correlated with PHQ-9 score (r=0.824, P<0.01). Gender, family socioeconomic status, degree of psychological pressure exerted by academic studies or job seeking, amount of hours spent on Internet per day, frequency of physical exercise, and the presence or absence of anxiety symptom and depression symptom were effective factors in predicting the insomnia symptom in higher vocational college students (P<0.01 or 0.05). ConclusionFemale gender, average and below average family socioeconomic status, moderate-to-severe degree of psychological pressure exerted by academic studies or job seeking, spending 2~5 h, 5~7 h or >7 h on Internet per day, inadequate physical exercise and presence of depressive symptom are the risk factors for insomnia symptom in higher vocational college students.[Funded by Sichuan Provincial Primary Health Development Research Center in 2022, North Sichuan Medical College (number, SWFZ22-C-89)]
RESUMO
OBJECTIVES: To assess functional integrity of the auditory brainstem in neonates with transient low Apgar scores. METHODS: Forty-two term infants were studied with brainstem auditory evoked response (BAER) using the maximum length sequence during the first month of life. All had transient low Apgar scores but no clinical signs of hypoxic-ischaemic encephalopathy (HIE). RESULTS: The latencies of BAER waves I and III in these infants were similar to those of age-matched normal controls at all click rates (91/s, 227/s, 455/s and 910/s) during the period studied. Wave V latency was increased at 910/s on day 1 (P<0.01), but did not differ from that in the controls on any other days. I-V interval was increased significantly at 455/s and 910/s on day 1 (P<0.01 and 0.001) and day 3 (P<0.05 and 0.01). On days 5 and 7, BAER wave latencies and intervals were similar to those in the controls. On day 30, all latencies and intervals reached the values in the controls. No abnormalities were seen in BAER wave amplitude variables on any days. CONCLUSIONS: Neonates with transient low Apgar scores but without HIE had a significant increase in I-V interval at very high click rates on the first three days of life. SIGNIFICANCE: Brainstem auditory function is sub-optimal during the first few days in neonates with transient low Apgar scores.

Prostate cancer is one of the common diseases affecting men′s health. Early diagnosis and treatment can make a difference in greatly improving the prognosis of patients. At present, prostate specific antigen (PSA), the most widely used serum indicator in prostate cancer screening, plays an important role in improving the early diagnosis rate and reducing mortality, but the high sensitivity of PSA makes many non-prostate cancer patients receive unnecessary puncture biopsies or overtreatment. Compared with PSA, prostate health index (PHI) has higher diagnostic value. PHI can reduce unnecessary puncture biopsies, and evaluate the prognosis of patients after prostatectomy (RP), which can motivate patients to actively monitor and provide important information for clinicians to formulate the following treatment plan. This article reviews the diagnostic value of PHI in prostate cancer, the relationship with tumor volume, the combined diagnosis with other imaging tests, and the prognostic value for patients undergoing RP.
RESUMO
Considering the existing shortages in evaluation criteria, training systems and management modes, administrators from graduate schools of Shanghai Jiao Tong University School of Medicine (SJTUSM) performed reforms and practice for the establishment of tutor teams which should meet the requirements for culturing talented medical graduates in recent years. We have established a multidimensional evaluation criteria system oriented by both representative academic achievements and the quality of graduate students. We have strengthened horizontal cooperation with relevant administrative departments in SJTUSM. We also emphasize the concepts of "training the trainees" coordinated with administrators in the training units to implement reform measures. Herein we have summarized the main reform measures in SJTUSM to constantly improve the quality of postgraduate tutor team and guarantee high-level postgraduate education.
RESUMO
Objective:To understand the relationship between the living environment and respiratory diseases in primary school students in Taizhou City of Zhejiang Province, and to explore the related factors. Methods:From 2018 to 2019, a total of 1 044 students from grade 2 to grade 5 of a primary school in Taizhou were selected by cluster random sampling method for two consecutive years to conduct a questionnaire survey during November 15 to December 31. Correlation between living environment and respiratory diseases in primary school students was analyzed. Results:Among the 1 044 students completed valid questionnaires, 224 students had suffered from respiratory diseases in the past year, accounting for 21.5% from 2018 to 2019. Logistic regression analysis showed that existence of waste collection site within 100 m of household (OR=2.522, 95%CI:1.105-5.752), family passive smoking exposure (OR=1.781, 95%CI: 1.234-2.571), and household use of air pollution chemicals (OR=1.915, 95%CI:1.396-2.627) were independent risk factors for respiratory diseases in primary school students. Conclusion:There are some risk factors of respiratory diseases in the living environment of primary school students in Taizhou, and prevention should be carried out in daily life to reduce the prevalence of respiratory diseases among primary school students.
RESUMO
Sepsis, a common critical disease in the intensive care unit(ICU), features high morbidity and mortality. At present, it is mainly tackled with western medicine, which may trigger a series of problems like antibiotic resistance, adverse hormonal reactions, and high cost after a long-term use. Therefore, exploring new efficient, safe, and cheap drugs and treatment modes has become the focus of our research at this stage. By virtue of unique advantages including "the concept of holism and individualized treatment based on syndrome differentiation", Chinese medicine has accumulated quite rich experience in the prevention and treatment of sepsis. In recent years, research on the regulation of Chinese medicine on nuclear transcription factor-κB(NF-κB) signaling pathway in sepsis has kept emerging. On this basis, this paper reviewed the etiology and pathogenesis of sepsis, syndrome differentiation and treatment, NF-κB signaling pathway, and its intervention with Chinese medicine. It has been found that some single Chinese herbs and their extracts, Chinese herbal compounds, and Chinese herbal injections effectively inhibit the expression of such inflammatory factors as NF-κB-mediated tumor necrosis factor-α(TNF-α), interleukin-1(IL-1), and IL-6 as well as the related proteins, reduce the systemic inflammatory response and organ injury, and improve the prognosis by regulating the activation of NF-κB signaling pathway and the immune function of macrophages. However, due to the limitations of objective conditions, some studies also have the problems of fuzzy pro-inflammatory anti-inflammatory balance mechanism, unclear pharmacokinetics and low drug safety evaluation, which need to be further studied and explored in order to provide a new theoretical basis and diagnosis and treatment thinking for the treatment of sepsis with traditional Chinese medicine.
RESUMO
This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder (ASD) in Chinese children. We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling. The Modified Chinese Autism Spectrum Rating Scale was used for the screening process. Of the target population of 142,086 children, 88.5% (n = 125,806) participated in the study. A total of 363 children were confirmed as having ASD. The observed ASD prevalence rate was 0.29% (95% CI: 0.26%-0.32%) for the overall population. After adjustment for response rates, the estimated number of ASD cases was 867 in the target population sample, thereby achieving an estimated prevalence of 0.70% (95% CI: 0.64%-0.74%). The prevalence was significantly higher in boys than in girls (0.95%; 95% CI: 0.87%-1.02% versus 0.30%; 95% CI: 0.26%-0.34%; P < 0.001). Of the 363 confirmed ASD cases, 43.3% were newly diagnosed, and most of those (90.4%) were attending regular schools, and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity. Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children.

RESUMO
AIM: Our previous studies showed increased sensitivity to 5-FU in colon cancer cell lines with microsatellite instability, and considered that mutations of TGFbeta-R II, IGF IIR, RIZ gene might enhance the potentials of cell growth and proliferation, which increased the sensitivity to 5-FU. Here we compared the distribution of cell cycle and P53 status between two human colon cancer cell lines with different sensitivity to 5-FU. Because mechanistic differences exist between 5-FU and CDDP, we also analyzed the efficacy of CDDP and combination therapy on two human colon cancer cell lines. METHODS: We compared the sensitivity to CDDP of these two cell lines by MTT assay. Distribution of cell cycle under treatment of 5-FU, CDDP alone or both was analyzed by Flow Cytometry, and expression of P53 was detected by immunocytochemical staining. RESULTS: SW480 cells were more sensitive to CDDP than LoVo cells at the concentrations above 16 micromol/l (Ratio of absorption is 0.64 and 0.79 at 16 micromol/l, respectively; P<0.01). Efficacy of combination therapy was conversely lower than that of single-therapy of 5-FU (Ratio of absorption in LoVo+5-FU, SW480+5-FU, LoVo+5-FU+CDDP and SW480+5-FU+CDDP is 0.53, 0.54, 0.72, 0.78, respectively; P<0.01). LoVo cells were negative whereas SW480 cells positive in P53 expression. 5-FU induced G1-phase arrest in both cell lines, but LoVo cells peaked 24 hours earlier than SW480 cells, and 48 hours earlier for an apparent hypodiploid DNA. However, CDDP showed the contrary, inducing S-phase arrest, and SW480 cells peaking 36 hours earlier. Both cell lines showed hypodipliod nuclei 48 hours after CDDP treatment. Percentage of cells in G1-phase and S-phase dominated alternatively under combination therapy in both cell lines. CONCLUSION: These results suggest that colon cancer cells with microsatellite instability are more sensitive to 5-FU, whereas more resistant to CDDP. Combination therapy of 5-FU and CDDP shows fewer efficacies than 5-FU single-therapy, although it can render a cell cycle arrest. P53 may be involved in the shift of G1-phase to S-phase, but inessentially.

OBJECTIVE@#To analyze the correlation of EBV infection with expression of TNF-α-inducing protein 3 gene and A20 protein in Hodgkin lmphoma.@*METHODS@#The clinical data and pathological specimens of 65 cases of Hodgkin's lymphoma in our hospital were analyzed retrospectively, and the tissue chips were made for the rich area of the tumor cells. The latent membrane protein 1 encoded by EBV was measured by immunohistochemical staining, and the RNA encoded by EBV was measured by in situ hybridization to analyze the infection state. The gene expression of tumor necrosis factor.α-induced protein 3 was detected by fluorescence in situ hybridization, and the expression of A20 protein encoded by EBV was detected by immunohistochemical staining. The obtained data were processed by SPSS 23.0 version statistical software.@*RESULTS@#The positive rate of latent membrane protein 1 was 26.15% (17/65), the positive rate of EBV encoded RNA was 26.15% (17/65), and the coincidence rate was 100.00%. In 65 patients, A20 protein expression was lost in 18 cases (27.69%), and 14 cases (21.54%) showed homozygous or heterozygous deletion of tumor necrosis factorα protein 3 gene. Only 1 case showed A20 loss combined with homozygous deletion of TNFα inducible protein 3. Correlation analysis showed that EBV infection did not significantly relate with expression loss of A20 protein and the gene deletion of TNF-α inducing protein 3 (P>0.05).@*CONCLUSION@#The expression loss of A20 protein and gene detection of TNFα inducing protein 3 are found in both EBV negative and positive patients with Hodgkin's lymphoma, however the results of immunohistochemical staining and fluorescence in situ hybridization are not complete consistant, the reason may closely relate with the technical factors.

The aim of the present study was to establish a cell model of volume-regulated anion channel subunit LRRC8A and investigate the physiological characteristics of LRRC8A. The eukaryotic expression vectors of LRRC8A and YFP-H148Q/I152L were constructed and transfected into Fischer rat thyroid (FRT) cells by Lipofectamine 2000. The FRT cell lines co-expressing LRRC8A and YFP-H148Q/I152L were obtained by antibiotic screening. The expression of LRRC8A and YFP-H148Q/I152L in FRT cells was detected by the inverted fluorescence microscope. The fluorescence quenching kinetic experiment was done to verify the function and effectiveness of the cell model. Then the cell model was utilized to study the physiological characteristics of LRRC8A, such as the characteristics of anion transport, the opening of LRRC8A by osmotic pressure, the effect of anion transport velocity, and the effect of chloride channel inhibitors on LRRC8A anion channel. The results of the inverted fluorescence microscope showed that LRRC8A was expressed on the cell membrane and YFP-H148Q/I152L was expressed in the cytoplasm. The results of fluorescence quenching kinetic test showed that under the condition of low osmotic state, LRRC8A could transport some kinds of anions, such as iodine and chloride ions. Osmotic pressure played a key role in the regulation of LRRC8A volume-regulated anion channel opening. Chloride channel inhibitors inhibited ion transport of LRRC8A channel in a dose-dependent manner. It is suggested that LRRC8A has the characteristics of classic volume-regulated anion channels by using the cell model of FRT cells co-expressing LRRC8A and YFP-H148Q/I152L.

This paper introduces the technical features of hydrosurgery system and evaluates it from three aspects:safety and effectiveness, economy and technology maturity. The evaluation results show that the safety and effectiveness are high, and the safety mainly involves the misuse of the system, which cause the adverse events. A large number of literatures have proved that the system is more suitable for the debridement of fine parts. It is estimated that hydrosurgery system has better economic performance, but the cost and patients' cost is also increased correspondingly. In the aspect of technology maturity assessment, this technology is a patented technology, and the number of published papers both at home and abroad is on the rise, indicating that the initial application of the technology is better and the technology is in infancy stage. Therefore, hydrosurgery system has certain advantages in all aspects. Hospitals need to allocate the equipment according to their own needs and clinical application, while a wider range of clinical trials is needed to provide evidence-based evidence for clinical applications and promotion.

The Autism Spectrum Rating Scale (ASRS) and the Social Responsiveness Scale (SRS) have been widely used for screening autism spectrum disorder (ASD) in the general population during epidemiological studies, but studies of individuals with intellectual disability (ID) are quite limited. Therefore, we recruited the parents/caregivers of 204 ASD cases, 71 ID cases aged 6-18 years from special education schools, and 402 typically developing (TD) children in the same age span from a community-based population to complete the ASRS and SRS. The results showed that the ID group scored significantly lower on total and subscale scores than the ASD group on both scales (P < 0.05) but higher than TD children (P < 0.05). Receiver operating characteristic analyses demonstrated a similar fair performance in discriminating ASD from ID with the ASRS (area under the curve (AUC) = 0.709, sensitivity = 77.0%, specificity = 52.1%, positive predictive value (PPV) = 82.2%) and the SRS (AUC = 0.742, sensitivity = 59.8%, specificity = 77.5%, PPV = 88.4%). The results showed that individuals with ID had clear autistic traits and discriminating ASD from ID cases was quite challenging, while assessment tools such as ASRS and SRS, help to some degree.
