Diabetes mellitus, characterized by glucose metabolism disorders and marked by insulin deficiency or insulin resistance, has seen a continuous rise in prevalence. In recent years, islet transplantation has matured as a therapeutic approach for diabetes, becoming an important method for glycemic control and the reduction of diabetes-related complications. Donor selection directly influences transplant outcomes, and various research institutions worldwide have proposed multiple scoring systems to optimize donor assessment, such as the University of Alberta scoring system and the North American Islet Donor Score. This article explores the impact of key factors such as donor age, body mass index and ischemia time on islet transplantation. Combining practical experience in pancreatic donor selection from Shanghai Changzheng Hospital, it proposes screening criteria for pancreatic donors suitable for China, aiming to provide new evidence for improving the success rate of islet transplantation.

With the aging of the global population， osteoporosis （OP） is becoming a major public health concern worldwide. Currently， the commonly used anti-osteoporosis drugs in clinical practice have limited application due to many side effects. Therefore， developing more effective and safer strategies for the prevention and treatment of OP has become a research focus in this field. In recent years， the clinical efficacy and advantages of traditional Chinese medicine （TCM） in treating OP have been gradually recognized. With the deepening pharmacological research on TCM for OP prevention and treatment， it is found that the active ingredients of Scutellaria baicalensis can promote bone formation or inhibit bone resorption by regulating signaling pathways， including Wnt/β-catenin， osteoprotegerin （OB）/receptor activator of nuclear factor-κB ligand （RANKL）/RANK （OPG/RANKL/RANK）， and bone morphogenetic protein 2 （BMP-2）/Smad， mitogen-activated protein kinase （MAPK）， and mammalian target of rapamycin （mTOR）. However， existing research on active ingredients of S. baicalensis for OP treatment is scattered， making it difficult for scholars to gain a systematic understanding of its research and application. This review summarized the literature on the active ingredients of S. baicalensis in OP treatment worldwide， clarified their mechanisms of action， and explored some issues， providing references for the integration of TCM in OP prevention and treatment.

This study systematically summarizes the achievements of viral hepatitis prevention and control in China， analyzes existing problems and challenges， and proposes comprehensive prevention and control strategies and measures to eliminate viral hepatitis as a public health threat based on the national conditions of China， in order to provide a reference for related departments in China on how to achieve the action targets for eliminating viral hepatitis as a public health threat by 2030.

ObjectiveTo study the pharmacological substances and mechanisms through which sesquiterpene ZH-13 from Aquilariae Lignum Resinatum improves neuroinflammation. MethodsBV-2 microglial cells were stimulated with lipopolysaccharide （LPS） to induce neuroinflammation. The cells were divided into the normal group， the model group， and the ZH-13 low- and high-dose treatment groups （10， 20 μmol·L^-1）. The model group was treated with 1 μmol·L^-1 LPS. Cell viability was assessed using the cell proliferation and activity assay （CCK-8 kit）. Nitric oxide （NO） release in the cell supernatant was measured using a nitric oxide kit （Griess method）. The mRNA expression levels of interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， inducible nitric oxide synthase （iNOS）， and interleukin-6 （IL-6） were detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The phosphorylation of mitogen-activated protein kinase （MAPK） pathway proteins was assessed by Western blot. ResultsCompared with the model group， ZH-13 dose-dependently reduced NO release from BV-2 cells under LPS stimulation （P<0.05， P<0.01）. In the 20 μmol·L^-1 ZH-13 treatment group， the mRNA expression levels of IL-1β， TNF-α， iNOS， and IL-6 were significantly reduced compared to the model group （P<0.05， P<0.01）. In both the low- and high-dose ZH-13 groups， the expression of the inflammatory factor TNF-α and the phosphorylation of c-Jun N-terminal kinase （JNK） in the upstream MAPK pathway were significantly reduced （P<0.05）. After stimulation with the JNK agonist anisomycin （Ani）， both low- and high-dose ZH-13 treatment groups showed reduced phosphorylation of JNK proteins compared to the Ani-treated group （P<0.01）. ConclusionThe sesquiterpene compound ZH-13 from Aquilariae Lignum Resinatum significantly ameliorates LPS-induced neuroinflammatory responses in BV-2 cells by inhibiting excessive JNK phosphorylation and reducing TNF-α expression. These findings elucidate the pharmacological substances and mechanisms underlying the sedative and calming effects of Aquilariae Lignum Resinatum.

AIM:To analyze the association between mobile phone addiction and high myopia among college students.METHODS:We conducted a cross-sectional questionnaire survey in December 2022 on all students of a university in Shaanxi Province, and the questionnaire included socio-demographic characteristics, mobile phone addiction, high myopia, and lifestyle. Binary Logistic regression model was used to analyze the association between mobile phone addiction and high myopia among college students.RESULTS:A total of 19 952 college students were included. The prevalence of high myopia was 7.31%. The rate of mobile phone addiction was 25.68%, and the mobile phone addiction score was 37.59±13.38. The incidence of high myopia among college students with mobile phone addiction was higher than non-mobile phone addiction(P<0.001). After adjusting for socio-demographic characteristics and lifestyle, the risk of high myopia among college students with mobile phone addiction was 1.274 times(95%CI:1.131-1.434)higher than non-mobile phone addiction. For each point increase of total mobile phone addiction score, withdrawal symptoms score, salience score, social comfort score, and mood changes score, the risk of high myopia among college students increased by 0.9%(95%CI:1.005-1.013), 2.0%(95%CI:1.010-1.030), 2.6%(95%CI:1.010-1.043), 4.8%(95%CI:1.030-1.066), and 3.3%(95%CI:1.014-1.052), respectively.CONCLUSION:Mobile phone addiction is significantly associated with the increased risk of high myopia among college students, and early intervention of mobile phone use may reduce the risk of high myopia among college students.

Background Air pollution exposure has a significant impact on maternal and child health. However, the research on the association between ambient ozone (O₃) exposure during pregnancy and the risk of premature birth in newborns is limited, and the conclusions are inconsistent. Objective To investigate the association of ambient O₃ exposure during pregnancy with the risk of preterm birth in Guangdong Province. Methods Data of pregnant women in Guangzhou from 2013 to 2019 and Foshan from 2018 to 2023 were collected, and O₃ concentrations during different trimesters were assessed according to maternal residential addresses. Bilinear interpolation was used to evaluate the concentrations of air pollution. A cohort study design was adopted in our study. Restricted cubic spline curves were used to evaluate the exposure-response relationship between O₃ exposure and preterm birth risk and explore potential exposure threshold of O₃. Logistic regression models were used to evaluate the association of O₃ exposure with preterm birth. Results A total of 702 924 pregnant women were included in this study, of whom 43 051 (6.12%) were preterm. The average O₃ exposure concentrations of pregnant women during the first, second, third, and whole trimesters were 95.51, 97.51, 100.60, and 97.87 μg·m⁻³, respectively. We observed J-shaped associations between O₃ exposure and preterm birth risk during the second, third, and whole trimesters of pregnancy using restricted cubic spline curves. This study found that there were threshold concentrations between O₃ exposure and preterm birth risk during different gestational periods, and the threshold concentrations in the first, second, third, and whole trimesters were 112.32, 99.83, 111.74, and 112.46 μg·m⁻³, respectively. During the second, third, and whole trimesters of pregnancy, after adjusting for maternal age, baby sex, pre-pregnancy body mass index, mode of delivery, baby birth weight, gestational diabetes, and gestational hypertension, the odds ratios (OR) of preterm birth were 1.02 (95%CI: 1.01, 1.04), 1.02 (95%CI: 1.00, 1.03), and 1.17 (95%CI: 1.13, 1.21) for each 10 μg·m⁻³ increase in O₃ concentration above the O₃ threshold. No significant association was found between O₃ exposure and the risk of preterm birth during the first trimester. Conclusion There is a nonlinear association between the risk of preterm birth and O₃ exposure during pregnancy, and higher concentrations of O₃ exposure during pregnancy are associated with the risk of preterm birth. Above the O₃ threshold concentration during pregnancy, especially during the second, third, and whole trimesters, the risk of preterm birth elevates with the increase of O₃ exposure concentrations.

BACKGROUND:Micro-abrasion,at-home whitening combined with infiltration resin have a good effect on dental fluorosis,but the effect of this method on micro-cracks in dental fluorosis is still unclear. OBJECTIVE:To explore the effect of micro-abrasion,at-home whitening combined with infiltration resin on micro-cracked dental fluorosis. METHODS:(1)Clinical research:A total of 23 patients with micro-cracked dental fluorosis,including 255 micro-cracked dental fluorosis,were selected from July 2020 to March 2021 in the Department of Prosthodontics,Stomatology Hospital,Tianjin Medical University.All of them received combined treatment of tooth micro-abrasion,at-home whitening and infiltration resin.The tooth color,tooth sensitivity,and tooth pain threshold were compared before treatment and 1 week and 1 month after treatment.(2)In vitro experiment:60 teeth with fluorosis with at least one crack on the tooth surface were collected and randomly divided into three groups for treatment.The control group was treated without any treatment.The whitening group was treated with micro-abrasion and at-home whitening,and the combined group was treated with micro-abrasion,at-home whitening,and infiltration resin,with 20 teeth in each group.The microhardness of the three groups of teeth samples after treatment was measured. RESULTS AND CONCLUSION:(1)Clinical study:6 months after treatment,among 255 teeth with micro-cracked dental fluorosis,whitening treatment for 207 teeth was significantly effective and whitening treatment for 48 teeth was effective,and the overall treatment efficiency was 100%.With the extension of treatment time,the proportion of moderate and severe dental sensitivity showed a decreasing trend.At 6 months after treatment,255 teeth with dental fluorosis had no severe sensitivity,15 with moderate sensitivity,125 with mild sensitivity,and 115 with no sensitivity,and the difference was significant compared with the sensitivity before treatment(P<0.05).There was no significant difference in the threshold of tooth pain before treatment and 1 week and 6 months after treatment(P>0.05).(2)In vitro experiment:The tooth microhardness of the whitening group was lower than that of the control group and the combined group(P<0.05),but there was no significant difference between the control group and the combined group(P>0.05).(3)The results show that the methods of micro-abrasion,at-home whitening combined with infiltration resin have good clinical efficacy in the treatment of micro-cracked dental fluorosis.

ObjectiveTo explore the effectiveness and potential mechanism of Shugan Jianpi Granules （疏肝健脾颗粒） combined with Chushi Zhiyang Ointment （除湿止痒软膏） in the treatment of atopic dermatitis with sleep disturbance of liver constraint and spleen deficiency syndrome. MethodsSixty-six patients with atopic dermatitis combined with sleep disturbance of liver constraint and spleen deficiency syndrome were randomly divided into 33 cases each in the treatment group and the control group. Both groups were treated with Chushi Zhiyang Ointment for external use. The treatment group additionally received Shugan Jianpi Granules orally， one dose per day； and the control group received cetirizine hydrochloride tablets orally， 10mg per day， taken before bedtime. Both groups were under the treatment for 4 weeks. Clinical effectiveness was evaluated after treatment， and the SCORing Atopic Dermatitis （SCORAD） index， pruritus visual analog scale （VAS） score， Insomnia Severity Index （ISI） score， and Pittsburgh Sleep Quality Index （PSQI） score were recorded before and after treatment， and serum levels of melatonin （MLT）， interleukin-4 （IL-4）， interleukin-6 （IL-6）， interleukin-13 （IL-13）， and tumor necrosis factor-α （TNF-α） were measured. The patients were also tested for blood routine， liver function and kidney function before and after treatment， and the occurrence of adverse events was also observed. ResultsThe total effective rate in the treatment group （90.63%， 29/32） was significantly higher than that in the control group （66.67%， 20/30， P＜0.05）. After the interventions， the scores for SCORAD， VAS， ISI， and PSQI， as well as the levels of IL-4， IL-6， IL-13， and TNF-α， were significantly reduced in both groups. In contrast， the MLT levels in treatment group significantly elevated compared to that before treatment （P＜0.05）. Comparing between the two groups after treatment， the scores of SCORAD， ISI， PSQI， and VAS， as well as the levels of serum IL-4 and IL-13 in the treatment group were significantly lower than those in the control group， while the MLT levels were markedly higher than that in the control group （P＜0.05 or P＜0.01）. There was no obvious abnormality in blood routine， liver function and kidney function in both groups when compared before and after treatment. The incidence rate of adverse reactions was 9.38% （3/32） in the treatment group and 13.33% （4/30） in the control group， and the difference between groups showed no statistical difference （P＞0.05）. ConclusionOn the basis of topical application of Chushi Zhiyang Ointment， the combined application of Shugan Jianpi Granules can significantly alleviate the degree of skin lesions and itching， and improve the quality of sleep in atopic dermatitis patients with sleep disturbance of liver constraint and spleen deficiency syndrome， and its mechanism may be related to regulating the immune balance， reducing the secretion of inflammatory factors， and elevating the level of MLT.

With the younger age of electronic device use and changes in lifestyle, the incidence of dry eye in children has significantly increased, becoming a research hotspot in clinical and scientific fields. Due to the dissociation of symptoms and signs, hidden manifestations, and complex etiology, children with dry eye form a special diagnostic and treatment group. Traditional dry eye detection methods have defects such as low cooperation from children, poor accuracy, and invasiveness, and the lack of a unified diagnostic guideline makes it difficult to accurately assess relevant indicators, urgently requiring scientific diagnostic technologies and standards. In recent years, new detection technologies have brought breakthroughs. The Keratograph 5M can objectively evaluate tear film stability and meibomian gland function; questionnaires such as DEQ-5 enhance the feasibility of subjective symptom feedback in young children; SM Tube test strips, with their rapid and non-invasive advantages, have become efficient tear screening tools; and the application of artificial intelligence(AI)has further revolutionized the diagnostic model, significantly improving diagnostic efficiency and children's compliance. However, existing technologies still face challenges such as difficulty in grassroots popularization, lack of child-specific reference values, and insufficient interdisciplinary data integration. Future efforts should focus on establishing age-stratified diagnostic criteria through multi-center collaboration, integrating AI with multimodal detection technologies, and constructing a diversified evaluation system to support early intervention and precision treatment for childhood dry eye. This paper systematically reviews the progress in detection technologies for childhood dry eye, focuses on the uniqueness of children as a special diagnostic and treatment group, discusses clinical difficulties and challenges, and integrates multimodal and intelligent methods to provide innovative solutions and practical pathways for precise diagnosis, reduction of misdiagnosis rates, and improvement of the diagnostic and treatment system for childhood dry eye.
