Objective: To investigate the current status and influencing factors of quality of life among HIV/AIDS cases, so as to provide the basis for improving HIV/AIDS cases quality of life. Methods: From March to July 2024, HIV/AIDS cases under follow-up management at various community health service centers in Jinshan District, Shanghai Municipality, were selected as the survey subjects using a convenience sampling method. Demographic information and receiving antiretroviral therapy (ART) were collected through questionnaire surveys. Quality of life was assessed using the Chinese version of the World Health Organization Quality of Life Questionnaire for HIV brief version. A multiple linear regression model was employed to analyze the factors affecting quality of life. Results: A total of 179 HIV/AIDS cases were investigated, including 150 males (83.80%) and 29 females (16.20%), with a mean age of (47.00±12.90) years. The subjective self-evaluation score for the quality of life among HIV/AIDS cases was (13.87±2.84) points. The scores in the domains of physical, psychological, independence, social relationship, environment, and spiritual support/religion/personal beliefs were (14.77±2.64) (13.57±2.04) (13.86±2.04) (12.99±2.26) (13.58±1.98) (14.59±3.05) points, respectively. Multiple linear regression analysis revealed statistically significant associations (all P<0.05) between the following factors and quality of life domain scores: educational level (college degree or above, β' =0.162) and receiving ART (β' =-0.197) were associated with the subjective self-evaluation domain score; educational level (college degree or above, β' =0.186) and receiving ART (β' =-0.299) were associated with physical domain score; receiving ART (β' =-0.263) and symptoms related to sexually transmitted diseases (β' =-0.243) were associated with psychological domain score; occupation (retirees, β' =-0.191) and symptoms related to sexually transmitted diseases (β' =-0.220) were correlated with the independence domain score; annual household income per capita (≥30 000 yuan, β' =0.281) and receiving ART (β' =-0.299) were correlated with the social relationship domain score; educational level (college degree or above, β' =0.206) and receiving ART (β' =-0.285) were correlated with the environment domain score; and receiving ART (β' =-0.492) and duration since HIV confirmation (3 to <6 years, β' =0.233; ≥6 years, β' =0.161) were correlated with the spiritual support/religion/personal beliefs domain score. Conclusions The overall quality of life among HIV/AIDS cases in Jinshan District is relatively good, but the domains of psychological, independence, and social relationship were still room for improvement. It is mainly influenced by factors such as occupation, educational level, annual household income per capita, receiving ART, symptoms related to sexually transmitted diseases, and duration since HIV confirmation.

To summarize the nursing care of a patient with acute myocardial infarction complicated with cardiogenic shock before operation.The main nursing points are as follows:in the acute stage,the integrated rescue was implemented with rapid on-machine coordination of external cardiopulmonary resuscitation,multidisciplinary collaboration to ensure safe patient transport;during the bridging period,the combined operation care of extracorporeal membrane oxygenation,intra-aortic balloon counter pulsation and continuous kidney replacement therapy was carried out with goal-oriented anticoagulation care,prevention of catheter-related infection with the assistance of mechanical circulation,and neurological function monitoring.The patient successfully passed the waiting period for heart transplantation and underwent heart transplantation 21 days after admission.With the follow-up for 1 year,the patient recovered well.

Under the background of high-intensity fattening,probiotics have gradually become wide-ly used feed additives.It can inhibit the proliferation of pathogenic bacteria,maintain the microeco-logical balance in the digestive tract,and improve the host immune function.In order to screen lac-tic acid bacteria strains with potential probiotic effects,23 acid-producing strains were isolated from rumen fluid of healthy Duolang sheep by CaCO3-MRS solid medium.Safe strains were re-screened through primary screening and hemolysis tests.Acid tolerance tests and bile salt tests were used to screen the strains that were relatively adapted to the rumen environment.The survival rate of the strain M2 was 93.80％under pH3.0 and 59.72％under bile salt concentration of 0.30％and the survival rate is higher than other strains under high temperature conditions.Subsequently,morphological observation,molecular biological identification,testing of pathogen antagonism,antibiotic tolerance analysis,growth characteristics detection and other methods were used to fur-ther explore the characteristics of the strain.The results showed that the strain to be tested was Gram-positive bacillus.After 16S rRNA gene sequence comparison,the strain was identified as Lactobac illus salivus,which could be used as a candidate strain to develop probiotics.The research results laid a foundation for its application in Duolang sheep breeding.

Programmed cell death protein ligand-1(PD-L1)is an important immune checkpoint molecule that plays an important role in regulating the body's immune response.Several clinical studies have shown that the expression level of PD-L1 in tumors is closely related to the efficacy of immune checkpoint inhibitors.Due to the spatial and temporal heterogeneity of tumors,immunohistochemical methods commonly used in clinical practice cannot accurately and comprehensively reflect the ex-pression level of PD-L1 in patients.Given that nuclear-medicine molecular imaging technology can noninvasively,real-time,dy-namically and visually monitor the expression level of PD-L1 in vivo at the molecular level,this article mainly focuses on the re-search of peptide-based radiolabeled molecular probes targeting PD-L1,with the aim of providing guidance for the search of no-vel peptide molecular probes for immunoimaging as well as for the screening of immunotherapy-suitable patients and evaluation of therapeutic efficacy,and other clinical applications.

Osteosarcoma is a common primary malignant bone tumor in adolescents and children,characterized by a high recurrence rate and metastasis,making its treatment extremely challenging.Traditional treatment modalities,including surgery,radiation therapy,and chemotherapy,can alleviate symptoms to some extent,but improving long-term survival rates remains a pressing issue.With the continuous development of immunotherapy,breakthroughs have been made in the research of tumor immune microenvironment and the application of immunotherapy in recent years,providing new perspectives and strategies for osteosarcoma treatment.Currently,immunotherapy strategies include tumor vaccines,targeted cytokines,immune checkpoint inhibition,adoptive cell therapy,combination therapy,etc.,significantly enhancing patient immune responses from the aspects of boosting immunity,overcoming immune tolerance,and preventing immune evasion,thereby effectively improving the patients'survival rates and prognosis.This review aims to systematically introduce the immune microenvironment of osteosarcoma and discuss the latest advances in immunotherapy in clinical translational research of osteosarcoma.By deeply understanding the immune characteristics of osteosarcoma and corresponding treatment methods,it is hopeful to provide more effective strategies for personalized treatment,contributing to the improvement of the patients' survival rates and prognosis.

Objective:To explore the optimization of the standardized assessment tool for clinical diagnosis of Chinese developmental dyslexia (DD).Methods:A cross-sectional study was conducted from May to December 2023, in which 130 primary school children in grades 1 to 3 with clinical signs of literacy lag and positive screening results on the screening scales were recruited from the outpatient clinic of Child Health Care Medical Division, Shanghai Children′s Hospital, Shanghai Jiao Tong University School of Medicine. Chinese dyslexia screening behavior checklist for primary students (CDSBC) was used as the screening scales, and supplemented by dyslexia checklist for Chinese children. Referring to the standard procedure of the"expert advice on diagnosis and intervention of Chinese developmental dyslexia", the developmental dyslexia scale for standard mandarin (DDSSM) was used to evaluate the children′s literacy-related cognitive abilities and conduct the diagnostic assessment, and divided the children into learning backward group and the DD group. The t-test and χ2 test were used to compare the differences in the distribution of intelligence, literacy and attention deficit hyperactivity disorder between the two groups. Spearman′s correlation was used to analyze the correlation between the scores for each cognitive ability in the DDSSM and the CDSBC. Results:Of the 130 children, 90 were male, aged (8.3±1.0) years; 40 were female, aged (8.1±0.9) years. A final diagnosis of DD was made in 59 cases, of which 41 were males. There was no statistically significant difference in operational intelligence quotient (101±15 vs.100±15, t=0.53, P>0.05) and statistically significant difference in literacy of DDSSM (32±5 vs.21±4, t=11.56, P<0.001) between the learning backward group and the DD group. Eighteen cases (25.4%) of the learning backward group were children with attention deficit subtype attention deficit hyperactivity disorder (ADHD-I), and 16 cases (27.1%) in DD group, the difference in incidence between the two groups was not statistically significant ( χ2=0.05, P>0.05). There were correlations between the DDSSM (for oral vocabulary, morphological awareness and orthographic awareness) and the CDSBC total score ( r=-0.42, -0.32, -0.35, all P<0.01), but the correlations for visuospatial perception and rapid automatized naming with CDSBC total score were not statistically significant ( r=-0.09 and -0.20,both P>0.05). Conclusion:For literacy-related cognitive abilities, screening scales CDSBC are not sufficiently useful for assessment, so the introduction of standardized assessment tools DDSSM is an optimization of the clinical diagnosis of Chinese DD, which is crucial for achieving accurate diagnosis and intervention.

OBJECTIVE To analyze the current status， hotspots and development trends of research on the treatment of non-alcoholic fatty liver disease （NAFLD）， providing reference for subsequent research. METHODS Searching the Web of Science database， the literature related to the treatment of NAFLD from the establishment of the database to December 31， 2022 were collected. CiteSpace 6.1.R6 was used to construct a visual atlas， perform collaborative network analysis on authors， countries and institutions， and conduct keyword co-occurrence， clustering and emergence analysis to explore its research status and hotspots. RESULTS A total of 3 882 articles were included， and the number of publications had been increasing year by year. The top three countries in terms of publication volume were China， the United States， and Japan. The author with the highest volume of publications was Sanyal from the United States （37 articles）， while the institution with the highest volume of publications was the University of California， San Diego （75 articles）. A closely connected research team abroad mainly conducted large-scale randomized controlled trials （RCT） to evaluate the effectiveness and safety of various interventions， including medication and lifestyle， in treating NAFLD. However， domestic researches mainly focused on basic researches about the treatment of NAFLD with effective medicinal ingredients， and were characterized by traditional Chinese medicine. There were relatively few high-quality large-scale RCT studies related to it. Keyword analysis showed that researches in various countries mainly focused on regulating liver oxidative stress and inflammation， improving the overall balance of glucose and lipid metabolism. Except for hypoglycemic drugs， drugs that act on various comprehensive metabolic homeostasis targets in the body had entered clinical research， and had enormous therapeutic potential. CONCLUSIONS The research on NAFLD treatment continues to grow in popularity and tends to research targets and drugs for regulating systemic metabolic homeostasis. As the main force of research， China should strengthen communication with the international community， grasp the trends and directions of basic research， attach importance to clinical research， and continuously tap the therapeutic potential of traditional Chinese medicine.

Objective To explore the application of the TST-IGRA two-step method in the screening of close contacts of active tuberculosis patients among three high schools in Jinshan District in 2020-2021，and to provide evidence for improving the prevention and control of tuberculosis in schools. Methods Three school tuberculosis outbreaks in Jingshan District from 2020 to 2021 were included in the present study. After excluding active tuberculosis, tuberculin skin test and γ-interferon release assay (IGRA) were conducted to screen latent infection of Mycobacterium tuberculosis in close contacts, and the necessity of the two-step method was analyzed. Results A total of 362 close contacts were screened in the three outbreaks, and 350 people were tested by TST. Comparing the results of TST and IGRA among different types of close contacts, it was found that the positive rate of TST in teachers was higher than that in students（54.84% vs 20.38%，P<0.05）. The positive rate of TST among students from high-burden areas of pulmonary tuberculosis in Shanghai was higher than that of local students（24.71% vs 18.80%，P<0.05). IGRA detection was performed on those with moderate and strong positive TST results, and the results showed that the positive rate of IGRA in those with strong positive TST results was only 17.7%, with Kappa value of 0.3. Conclusion The prevention and control of tuberculosis in school should strengthen the annual health examination of teachers and staff, promote timely medical treatment for suspected tuberculosis symptoms, reasonably increase the screening frequency of students in high-burden areas of tuberculosis in Shanghai, and collect students’ previous history of tuberculosis exposure. When screening close contacts, after excluding active tuberculosis, it is recommended that TST and IGRA should be combined to determine latent Mycobacterium tuberculosis infection and achieve accurate intervention.
