Objective: To examine the associations between three adipokines (omentin-1, nesfatin-1 and apelin) and diabetic retinopathy (DR) among patients with type 2 diabetes mellitus (T2DM), so as to provide the basis for the prevention and control of DR. Methods: The T2DM patients hospitalized in Lishui TCM Hospital from August 2021 to May 2023 were selected and divided into three groups: no diabetic retinopathy (NDR) group, non-proliferative diabetic retinopathy (NPDR) group, and proliferative diabetic retinopathy (PDR) group based on fundus fluorescein angiography. Data on gender, age, and course of T2DM were collected through questionnaires, and serum omentin-1, nesfatin-1, apelin, and related blood biochemical indicators were measured. The associations of omentin-1, nesfatin-1 and apelin with DR were analyzed using a multinomial logistic regression model. Results: A total of 150 T2DM patients were enrolled, including 58 cases in the NDR group, 60 cases in the NPDR group, and 32 cases in the PDR group, with males accounting for 60.34%, 45.00% and 68.75%, respectively. The mean ages were (54.79±14.40), (57.03±12.20) and (57.72±10.70) years, respectively. The median (interquartile range) courses of T2DM were 7.00 (7.75), 10.00 (8.00) and 10.00 (5.00) years, respectively. Compared with the NDR group, the NPDR group had lower levels of omentin-1 and nesfatin-1 and higher level of apelin, while the PDR group had higher level of omentin-1 and lower level of apelin (all P<0.05). Compared with the NPDR group, the PDR group had higher levels of omentin-1 and nesfatin-1 and lower level of apelin (all P<0.05). Multinomial logistic regression analysis showed that omentin-1 level was statistically associated with NPDR (OR=0.503, 95%CI: 0.291-0.871) and PDR (OR=7.862, 95%CI: 2.956-20.910); nesfatin-1 (OR=0.971, 95%CI: 0.953-0.989) and apelin (OR=3.266, 95%CI: 1.817-5.868) levels were statistically associated with NPDR. Conclusion Serum levels of omentin-1, nesfatin-1 and apelin were associated with different stages of DR among T2DM patients.

Stroke is the main cause of death and disability among adults in China and is characterized by high incidence， disability， mortality， and recurrence rates. The combination of traditional Chinese and Western medicine has great potential in treating stroke and its sequelae. The classic traditional Chinese medicine prescription Da Chengqitang （DCQT） has a long history and proven efficacy in treating stroke. Clinically， DCQT is often used to treat stroke and its sequelae. However， the number and quality of clinical trials of DCQT in treating stroke need to be improved. Because of the insufficient basic research， the active ingredients and multi-target mechanism of action of DCQT remain unclear. Our research group has previously confirmed that DCQT can effectively reverse neurological damage， reduce iron deposition， and downregulate the levels of pro-inflammatory cytokines in the rat model of hemorrhagic stroke. The treatment mechanism is related to the nuclear factor erythroid 2-related factor 2 （Nrf2）-mediated signaling pathway and p38 mitogen-activated protein kinase （MAPK） signaling-mediated microglia activation. To clarify the pharmacodynamic basis and anti-stroke mechanism of DCQT， this article reviews the research progress in the treatment of stroke with DCQT in terms of clinical trials， pharmacodynamic material basis， safety evaluation， and mechanisms of absorbed components. This article summarizes 45 major phytochemical components of DCQT， 11 of which are currently confirmed absorbed components. Among them， emodin， rhein， chrysophanol， aloe-emodin， synephrine， hesperidin， naringin， magnolol， and honokiol can be used as quality markers （Q-markers） of DCQT. The mechanism of DCQT in treating stroke is complex， involving regulation of inflammatory responses， neuronal damage， oxidative stress， blood-brain barrier， brain-derived neurotrophic factor， and anti-platelet aggregation. This article helps to deeply understand the pharmacodynamic basis and mechanism of DCQT in treating stroke and provides a theoretical basis for the clinical application of DCQT in treating stroke and the development of stroke drugs.

Abstract Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

Cell-free DNA (cfDNA) is the DNA fragment existing in human extracellular fluid. In specific physiological process (such as pregnancy) or pathological conditions (such as human malignancies), the contents of cfDNA in extracellular fluid will abnormally change. The contents and molecular characteristics of cfDNA make it have the potential as a kind of biomarker for diseases′ diagnosis. With the development of cfDNA detection technology such as sequencing and mass spectrometry, liquid biopsy based on cfDNA detection has been widely used in clinical tumor diagnosis, tumor treatment, prenatal examination, and research in autoimmune diseases. A systematic summary of the latest research progress in the development of cfDNA detection technology and the clinical application of liquid biopsy, as well as the research progress of cfDNA in the diagnosis and treatment of related diseases is summarized in this review.

The expression of citrullinated histone H3 （CitH3） in ankle joint as well as the expressions of cytochrome P450 24A1 （CYP24A1）， cytochrome P450 27B1 （CYP27B1），vitamin D receptor （VDR） and peptidyl arginine deiminase 4 疾病。E-mail：zhongyao626@126.com （PAD4） in synovium were all determined. RESULTS Compared with the model group， the toe swelling degree and AI score in the middle-dose and high-dose groups of petroleum ether extract of S. divaricata decreased significantly from day 14 to day 28 after administration （P＜0.05 or P＜0.01）. The serum levels of IL-1β， IL-17， TNF-α， MPO， NE and NETs decreased significantly， while the levels of IL-10 and 25（OH）D3 increased significantly （P＜0.05 or P＜0.01）. The widened ankle joint space and the improved structure were found； the expression of CitH3 in ankle joint， and the expressions of CYP24A1 and PAD4 in synovium were down-regulated significantly， while the expressions of CYP27B1 and VDR were up-regulated significantly in synovium （P＜0.05 or P＜0.01）. CONCLUSIONS The petroleum ether extract of S. divaricata may inhibit the production of NETs and improve the symptoms of RA by regulating the vitamin D system.

Objective To explore the characteristics of blood lipid metabolism indicators and risk factors of prognosis in children with systemic lupus erythematosus (SLE). Methods A total of 54 children who were diagnosed with SLE and hospitalized in Chengdu Women and Children’ s Central Hospital from January 2013 to August 2022 were selected. Clinical data of all children were collected and blood lipid metabolism indicators and biochemical indicators were detected , and binary logistic regression was used to analyze the prognosis risk factors in children with SLE. Results Among the 47 cases (87.04%) had abnormal blood lipid metabolism at admission, and is mainly manifested as elevated levels of LDL-C, TG and TC and decreased level of HDL-C. The proportion of cardiovascular system damage, hematological system damage, urinary protein positivity, and SLEDAI-2000 score in the group with good prognosis were lower than those in the group with poor prognosis, while the proportion of dsDNA positivity was higher in the group with poor prognosis. Binary Logistic regression analysis showed that the cardiovascular system damage and positive urinary protein were risk factors for poor prognosis, with statistically significant differences (P<0.05). Conclusion Abnormal blood lipid metabolism is common in children with SLE, and cardiovascular system damage and positive urinary protein may increase the risk of poor prognosis in young children.

BACKGROUND:The application of miniscrew in adolescents is increasing day by day,but at present,there are few studies on bone mass in the external oblique line of the mandible in adolescents at home and abroad,and there is no systematic study on bone mass in the external oblique line of the mandible in adolescents in different growth and development periods. OBJECTIVE:To measure the bone mass in the external oblique line of the mandible in adolescents with different cervical vertebral bone ages using a cone-beam CT and to investigate the difference of bone mass in the external oblique line of the mandible in adolescents with different cervical vertebral bone ages and the correlation between bone mass in this area and the cervical vertebral bone age. METHODS:The cone-beam CT data of 105 adolescent patients before orthodontic treatment were collected and divided into CS3 group(n=24),CS4 group(n=26),CS5 group(n=29)and CS6 group(n=26)using the cervical vertebral maturation method.The adolescent mandibular buccal shelf was reconstructed by Mimics Medical 21.0 software.The width of buccal bone at 6 and 11 mm under the cemento-enamel junction and the bone height at 4 and 5 mm buccal to the cemento-enamel junction of right mandibular first and second molars were measured.The measured data were statistically analyzed.The measurement was made on four planes:plane 1 is the plane where the proximal mesial root of the mandibular right first molar is located;plane 2 is the plane where the distal mesial root of the mandibular right first molar is located;plane 3 is the plane where the proximal mesial root of the mandibular right second molar is located;and plane 4 is the plane where the distal mesial root of the mandibular right second molar is located. RESULTS AND CONCLUSION:In each group,the bone width on the buccal side of the external oblique line increased gradually from the first molar proximally to the second molar distally in adolescents,and the width of buccal bone at 6 and 11 mm under the cemento-enamel junction showed significant difference among different layers(P<0.05).The bone width of buccal bone at 11 mm under the cemento-enamel junction was greater than that at 6 mm.The bone height on the buccal side of the external oblique line increased gradually from the first molar proximally to the second molar distally in all four groups,and the bone height at 4 and 5 mm buccal to the cemento-enamel junction showed significant differences at different layers(P<0.05).The bone height at 4 mm buccal to the cemento-enamel junction was greater than that at 5 mm.On the fourth plane,the bone width at 11 mm buccal to the cemento-enamel junction was smaller in the CS3,CS4,and CS5 groups than in the CS6 group(P<0.05).On the third plane,the bone heights at 4 mm and 5 mm buccal to the cemento-enamel junction were smaller in the CS3 and CS4 groups than in the CS6 group(P<0.05).On the fourth plane,the bone height at 5 mm buccal to the cemento-enamel junction was smaller in the CS3 and CS4 groups than in the CS6 group(P<0.05).On the fourth plane,the bone height at 4 mm buccal to the cemento-enamel junction was smaller in the CS3 group than in the CS6 group(P<0.05).Spearman correlation analysis showed that there was no correlation between bone mass and the cervical vertebral bone age,except that there was a weak correlation between bone mass at some measurement sites and cervical vertebral bone age.To conclude,the bone mass in the external oblique area of the mandible in adolescents does not change significantly with the increase of cervical vertebral bone age.The buccal side of the mesial root and distal root of the mandibular second molar in the external oblique area of CS3-CS6 adolescents meets the requirement of bone mass for miniscrew implantation,which is a site available for miniscrew implantation.

BACKGROUND:Traditional lateral cephalometric radiographs always suffer from some problems,such as magnification distortion,left and right overlap inconsistency and so on,while the cone-beam CT can truly display the three-dimensional structure of the craniofacial region.Performing three-dimensional reconstruction of cone-beam CT and then transforming the cone-beam CT in the selected area into the two-dimensional image can make the overlap between the left and right sides consistent and reduce the influence of surrounding tissue structures. OBJECTIVE:To explore the consistency of quantitative analysis of cervical vertebral bone age between two kinds of cone-beam CT transformed two-dimensional images with different integrated thicknesses and traditional lateral cephalometric radiographs. METHODS:The cone-beam CT and lateral cephalometric radiograph data of 118 adolescent orthodontic patients were collected.Firstly,the cone-beam CT image was reconstructed in 3D imaging software.After reconstruction,two types of cone-beam CT images with different integrated thicknesses were selected in the sagittal interface and transformed into two-dimensional images,which were named ICB-1 and ICB-2,respectively.The Zhibeiyun system was used to measure and calculate the angle between the concave base of the second cervical vertebra and the lower edge of the vertebral body(@2),the ratio of the third cervical spine to the posterior height(AH3/PH3),the ratio of height to width of the fourth cervical spine(H4/W4)in lateral cephalometric radiograph,ICB-1,ICB-2 and the cervical vertebral bone age.After an interval of two weeks,20 adolescents were randomly selected to repeat the above measurements.The intraclass correlation coefficient(ICC)method was used to evaluate the repeatability of the three images in measuring cervical bone age.Paired t-test was used to analyze the consistency of cervical bone age measurements between the three images.The Kappa test was used to analyze the consistency of cervical vertebral bone age staging assessment between the three images. RESULTS AND CONCLUSION:(1)ICC of AH3/PH3 in the lateral cephalometric radiograph group was<0.9,and the ICC of other measurement items in each group was>0.9.(2)Paired t-test results showed that there were statistical differences in AH3/PH3 and H4/W4 between the ICB-1 group and lateral cephalometric radiograph group and between the ICB-1 group and ICB-2 group(P<0.05),and there were no statistically significant differences in the other items between the three groups(P>0.05).(3)The Kappa test results showed that the Kappa coefficients of the two groups were all more than 0.8 according to the staging of cervical vertebral bone age in three groups(P<0.001).(4)It is indicated that the repeatability of ICB-1 and ICB-2 in the measurement of cervical vertebral bone age is better than that of lateral cephalometric radiographs.Lateral cephalometric radiographs,ICB-1 and ICB-2 have good consistency in the measurement of cervical vertebral bone age,but considering the integrity of cervical vertebra structure,ICB-2 is more suitable for quantitative analysis of cervical vertebral bone age than ICB-1.
