As one of the common negative emotions in diabetic patients, diabetes distress not only directly weakens patients' self-efficacy and treatment compliance, but also increases the risk of complications. With the help of mobile applications, chatbots, virtual reality technology and other means, digital health interventions can effectively alleviate the negative emotions of diabetic patients, improve their self-management ability and confidence, and are increasingly widely used in diabetes distress. The purpose of this review is to introduce the specific forms, application effects and future development directions of digital health intervention in diabetes distress, and to promote further research and clinical practice of digital health intervention in diabetes distress.

Chimeric antigen receptor gene-modified T lymphocytes(CAR-T cells)have made significant progress in the treatment of hematologic malignancies.However,the uncertainties and lack of controllability associated with their in vivo behavior remain major limitations to their clinical application.Uncontrolled or inappropriate activation of CAR-T cells at unintended locations can lead to reduced antitumor efficacy or unpredictable adverse reactions.Enabling CAR-T cells to exhibit predictable and controllable behavior in vivo,with activation occurring at the right location and at the appropriate intensity,holds the potential to significantly enhance their antitumor effectiveness and minimize adverse effects.This article systematically reviews recent strategies for"remotely controlling"CAR-T cell activity in vivo through innovative designs that allow precise regulation of CAR-T cell activity and behavior.Achieving safe,targeted,and efficient antitumor responses represents one of the key directions for the future development of CAR-T cell therapies.

Objective To investigate the effect of ethanolic extract of Cichorium glandulosum Boiss.et Huet.on fecal bile acid profiles in high-fat-diet-induced obese mice.Methods Twenty-four 6-week-old C57 BL/6 male mice were divided randomly into normal,model,drug-administration,and metformin groups.Mice in the normal group were fed a regular diet and mice in the other three groups were given high-fat diets.The drug-administration group was gavaged with 10 mL/kg ethanol extract of Cichorium glandulosum Boiss.et Huet.daily,and the metformin group was gavaged with 10 mL/kg metformin daily.After 10 weeks,livers were collected to measure hepatic total triglycerides(TG),total cholesterol(TC),low-density lipoprotein-cholesterol(LDL-C),and high-density lipoprotein(HDL)-C.Feces were collected and analyzed.Results Body weight(P＜0.0001),liver TG(P＜0.05),and TC(P＞0.05)were all significantly higher in model mice compared with normal mice,while LDL-C(P＞0.05)and HDL-C(P＜0.001)were significantly lower,indicating abnormal weight gain and lipid metabolism.Alcoholic extract of Cichorium glandulosum Boiss.et Huet.significantly reduced body weight(P＜0.0001),liver TG(P＜0.0001),serum TG(P＜0.05),TC(P＜0.01),and LDL-C(P＜0.05)in mice.Methodsological validation showed that the current method could accurately quantify 52 bile acids in feces.Analysis of the concentration of each type of bile acid revealed that alcoholic extract of Cichorium glandulosum Boiss.et Huet.significantly increased the secondary/primary bile acid ratio(P＜0.05).Multivariate analysis showed that the bile acid metabolic pattern was significantly altered in all groups.Eight differential bile acids were screened in the drug-administration group relative to the model group using variable importance of projection＞1 and P＜0.05.A search of the Kyoto Encyclopedia of Genes and Genomes database revealed that the differential bile acids were mainly involved in the secondary bile acid biosynthesis pathway.Correlation analysis showed that four differential bile acids,deoxycholic acid(r,=0.6445,P＜0.001),isolithocholic acid(r,=0.5879,P＜0.01),3β-deoxycholic acid(r,=0.6649,P＜0.001),and ω-rhamnoglutaric acid(rs=0.5387,P＜0.01),in feces were strongly positively correlated with body weight.Conclusions Cichorium glandulosum Boiss.et Huet.alcoholic extract may play a role in weight reduction and amelioration of dyslipidemia by modulating secondary bile acid biosynthesis and altering fecal bile acid metabolic profiles.

Objective To study the splenic injuries caused by high-altitude falling and underwater explosion and the 2-dimensional ultrasound and contrast-enhanced ultrasound(CEUS)characteristics.Methods Twenty-three healthy Beagle dogs were divided into high-altitude falling group(n=13)and underwater explosion group(n=10).Free-fall high-platform device and gram-grade trinitrotoluene were used to simulate high-altitude falling injury and underwater explosion injury in Beagle dogs,respectively.Ultrasound examination of the spleen was performed immediately after injury,with follow-up examinations every hour.CEUS examination was performed in surviving dogs.Spleen specimens were taken from deceased dogs after injury to observe gross injuries.Pathological changes in tissue morphology and cell apoptosis were observed by hematoxylin-eosin(H-E)staining.Results In the high-altitude falling model,6,2,1,and 1 dogs died in the 6 m,7 m,8 m,and 9 m groups,respectively;in the underwater explosion model,1 and 4 dogs died in the buoyancy and frogman groups,respectively.Two-dimensional ultrasound examination of the high-altitude falling model showed spleen rupture(disruption of splenic parenchymal structure),perisplenic fluid accumulation,subcapsular hematoma,intrasplenic hematoma,increased splenic vein echo,and uneven splenic parenchymal echo.Two-dimensional ultrasound examination of the underwater explosion model showed increased splenic vein echo and uneven splenic parenchymal echo,which were less serious compared with the high-altitude falling model.CEUS results indicated 4 major contrast patterns in both models.The Beagle dogs with type Ⅰ(large focal contrast defect),type Ⅱ(diffuse contrast defect),or type Ⅲ(no contrast agent entry into the splenic vein)contrast patterns all had splenic rupture after injury.H-E staining results showed true splenic rupture,diffuse intrasplenic hemorrhage,splenic hematoma/ecchymosis,subcapsular hematoma/ecchymosis,and venous congestion after spleen injury,which were consistent with the 2-dimensional ultrasound findings.Conclusion High-altitude falling causes more serious spleen injuries in Beagle dogs compared with underwater explosions.Routine ultrasound performs well in diagnosing typical splenic injuries,while CEUS has advantages in evaluating atypical splenic injuries and has good predictive ability for delayed splenic rupture.

Postoperative radiotherapy increase the overall survival rate offor breast cancer improves overall survivalpatients, but. Nevertheless, the heart is at risk of radioactive heart damageradiation-induced cardiac injury due to its anatomical location, which is inevitably exposed to radiation during radiotherapy. The heart is considered a "high-risk organ" sensitive to radiation, and its radiation dose should be as low as possible. Previous studies have evaluated the effect of overall heart radiation dose on long-term cardiovascular events, but the. However, new study has found that the average heart dose does not accurately reflect the degree of heart radiation exposure. In recent years, more and morewidespread attention has been paid to subclinical cardiac injury after radiotherapy, aiming at early identification of latent cardiac injury. In addition, the relationship between specific cardiac substructural doses and arrhythmias is unclear. This paper focuses onIn this article, the limitations of average cardiac dose in predicting radioactive heart injuryradiation- induced cardiac injury, the indicators of early identification of the indicators for cardiac injury and the influencing factors of radiation-induced cardiac injury in breast cancer radioactive heart injurywere illustrated, and focuses on the relationship between radiation damage of different cardiac substructures and arrhythmia was evaluated, so asaiming to achieve fine cardiac risk management in breast cancer patients and reduce the non-cancer mortality in breast cancer patients.

The CRISPR/Cas9 gene editing technology directs Cas9 protein to recognize, bind and cleave the target site specifically by using artificial single-guide RNA (sgRNA), through non-homologous end joining or homologous end-recombinant repair mechanisms of cells, which can be engineered to knockout or knock-in of genomes. RIG-I is a pattern recognition receptor that recognizes the 5'-triphosphate-containing RNA in the cytoplasm and activates IRF3/7 and NF-κB by interacting with the downstream signaling molecule MAVS, thus initiating the expression of type I interferons and inflammatory factors. Previous studies found that influenza B virus (IBV) can up-regulate the expression of RIG-I. In the present study, to explore whether RIG-I is the major receptor for IBV to active the antiviral innate immune response and its effect on IBV replication, RIG-I gene in 293T cells was knocked out by CRISPR-Cas9 system, and a stable RIG-I knockout 293T (RIG-I(-/-) 293T) cell line was screened by puromycin pressure. The results of Western blotting showed that RIG-I was not expressed in this cell line after IBV or Sendai virus (SeV) infection, indicating that the RIG-I(-/-) 293T cell line was successfully constructed. The transcription levels of interferons, inflammatory factors and interferon-stimulated genes in RIG-I(-/-) 293T cells which were infected by IBV decreased significantly compared with those in wild-type 293T cells. Moreover, the phosphorylation of p65 and IRF3 were not detected in IBV or SeV infected RIG-I(-/-) 293T cells. It is indicated that the expression of cytokines mainly depends on the RIG-I-mediated signaling pathway at the early stage of IBV infection. Furthermore, the multi-step growth curves of IBV in the wild type and RIG-I(-/-) 293T cells showed that RIG-I inhibited the replication of IBV. Collectively, the RIG-I knockout 293T cell line was successfully constructed. We found that RIG-I is the main receptor for IBV to active the antiviral innate immune response and is critical for inhibiting IBV replication, which lays the foundation for further study of IBV infection mechanism.

Objective To analyze the epidemiological characteristics of hepatitis B in Guangzhou from 2006 to 2018. Methods The data were retrieved from the National Infectious Disease Surveillance Information Report Management System. Descriptive methods were used to analyze and summarize the results. Chi-square test was used for statistical analysis of classification data, and Joinpoint software was used to analyze the annual change percentage and trend. Results A total of 292 674 cases of hepatitis B were reported in Guangzhou from 2006 to 2018, and the annual average reported incidence was 182.2 per 100,000. Chronic hepatitis B was the main type, accounting for 89.9%. The incidence rate of males (241.6 / 105) was higher than that of females (117.9 / 105), with a ratio of 2.0:1. During the period from 2006-2018, the reported incidence of hepatitis B in Guangzhou first increased, reached the highest in 2008, and then decreased year by year. There was no significant difference in the number of HBV cases among different months. The average onset age of hepatitis B reported in Guangzhou was 39.3 years old, and the average onset age increased year by year from 2006 to 2018. Conclusion The incidence rate of hepatitis B in Guangzhou has decreased since 2008, but it was still higher than the national average incidence rate. The hepatitis B infection in Guangzhou remains a big issue. It is suggested to further strengthen the prevention and control of hepatitis B in adults by maintaining a national immunization program for children, thereby reducing the epidemiological level of hepatitis B in Guangzhou.
