Objective To understand the status of body image disturbance and its influencing factors in patients with ankylosing spondylitis (AS), so as to provide a scientific basis for the clinical management of AS. Methods A total of 353 AS patients admitted from January 2022 to December 2024 were selected as research subjects. Chinese version of Body Image Disturbance Questionnaire (BIDQ) was used to investigate the body image disturbance in AS patients. Single factor analysis was performed by t test and analysis of variance, and multiple factors were analyzed by multivariate linear regression. Results The total score of BIDQ in 342 AS patients was (25.01±4.22). Multivariate linear regression analysis results showed that self-paid medical expense, nighttime VAS score and negative emotion PANAS score could positively predict body image disturbance in AS patients (standardized regression coefficient=0.413, 0.413, 0.460, P<0.05), and PSSS score, positive emotion PANAS score and exercise management CDSSM score could negatively predict body image disturbance (standardized regression coefficient=-0.245, -0.134, -0.247, P<0.05). Conclusion The body image disturbance in AS patients is worthy of clinical attention. Nighttime pain, negative emotion and self-paid medical treatment can increase the risk of body image disturbance. Positive emotion, social support and high self-management level of exercise behavior can reduce the formation of body image disturbance, which can provide new ideas for clinical management of AS patients.

Cardiotoxicity induced by antineoplastic agents is an important factor affecting the prognosis of cancer patients. This article systematically summarizes the clinical manifestations of cardiotoxicity caused by chemotherapeutic drugs, molecular targeted cancer therapies, and immunotherapeutic drugs, and identifies the core injury mechanisms, including cardiomyocyte apoptosis, oxidative stress, and mitochondrial dysfunction. In Traditional Chinese Medicine (TCM) theory, anticancer drug-induced cardiotoxicity falls under the category of “heat toxins” characterized by dual deficiency of qi and blood, upward flaming of heart heat, stagnation of the heart vessels, and meridian obstruction induced by phlegm-dampness. Therefore, by reviewing the preventive and therapeutic effects and the underlying mechanisms of tonic medicines, interior heat-clearing medicines, blood-circulating and stasis-resolving medicines, phlegm-transforming, cough-suppressing and panting-relieving medicines, and interior-warming medicines, this paper concludes that TCM prevention and treatment of this condition adheres to the formulation principle of “reinforcing healthy qi, removing toxins, and resolving blood stasis”. Its mechanisms of action—including antioxidation effects, regulation of autophagic balance, antagonism of inflammatory responses, and improvement of microcirculation—are highly consistent with modern medical treatment strategies (e.g., dexrazoxane for inhibiting iron-dependent oxidative stress, statins for anti-inflammatory effects). This study provides theoretical support and practical guidance for the collaborative and precise prevention and treatment of anticancer drug-induced cardiotoxicity through the integration of traditional Chinese and Western medicine.

Objective To establish the method of thin layer chromatography （TLC） for identification and content quantitative determination of Shugantongluo capsules, and provide methodological reference for the quality control of Shugantongluo capsules. Methods Bupleuriradix, polygala tenuifolia yuanzhi, and acorus tatarinowii rhizoma were identified by TLC qualitatively. The content of Saikosaponin-a was determined by HPLC method. The chromatography was performed on Venusil XBP C₁₈（L） （4.6 mm×150 mm, 5 μm） with a stable temperature of 30℃. The mobile phase in isocratic elution consisted of acetonitrile-water （40∶60, V/V） at the flow rate of 1.0 ml/min with an injection volume of 20 μl. The detection wavelength was set at 210 nm. Results Clear spots were obtained with good separation in TLC identification which was highly specific. The Saikosaponin-a at the range of 25.00-500.0 μg/ml was linear with peak area （r=0.999 9）, the average recovery rate was 97.00%, and RSD was 2.60%. Conclusion These methods was easy to operate with accurate results, with good specificity and reproducibility, which could be uesd for the quality control for Shugantongluo capsules.

ObjectiveTo describe the characteristics of cardiorespiratory fitness levels in the baseline population of the South China Cohort， and to identify the potential contributing factors. MethodsFace-to-face surveys and physical examinations were conducted to collect information on demographic characteristics， medical histories， medications， lifestyles， and physical activity conditions. After excluding individuals with missing cardiorespiratory fitness-related data and covariates including physical activity and dietary information， a total of 77 024 participants aged 25 to 85 were included. Cardiorespiratory fitness levels were evaluated using a non-exercise algorithm， and low cardiorespiratory fitness level was defined as below the lower tertile of the population distribution. Logistic regression analysis was used to examine the distribution of low cardiorespiratory fitness level， and log-binomial regression and ordered logistic regression analyses were used to analyze the associations of cardiorespiratory fitness with demographic characteristics， socioeconomic factors， lifestyle factors （including alcohol consumption and dietary diversity）， and chronic diseases conditions （including diabetes， hypertension， pulmonary diseases， and cardiovascular diseases）. ResultsCardiorespiratory fitness levels showed a sufficiently normal distribution in both male and female group. We found that the proportion of low cardiorespiratory fitness level was higher among Han ethnicity， those with an educational level below 9th grade， households with an annual income of more than 100 000 Yuan， as well as those who drank alcohol at least one time per week and who exhibited low dietary diversity （all P＜0.001）. Ethnicity， socioeconomic status， lifestyle factors， and chronic diseases were found to be statistically associated with cardiorespiratory fitness levels in the South China population （all P＜0.001）. ConclusionCardiorespiratory fitness levels varied across different population groups in South China， with ethnicity， socioeconomic status， lifestyle factors， and chronic diseases serving as key determinants. Therefore， it is recommended that the public pay attention to cardiorespiratory fitness， as strengthening population-level monitoring and interventions for cardiorespiratory fitness carries significant public health implications.

ObjectiveTo investigate the temporal trend of weight-adjusted-waist index （WWI） and its association with the risk of incident cardiovascular diseases （CVD） among middle-aged and older Chinese adults. MethodsBased on the China Health and Retirement Longitudinal Study （CHARLS）， this research enrolled participants aged 45 and above with complete physical measurement data from the 2011， 2013， and 2015 waves. Complex sampling weights were applied to calculate the mean WWI， and the Mann-Kendall test was used to analyze its trend. From the 2011 baseline survey， individuals with a history of cardiovascular disease or missing key covariates were further excluded. New-onset cardiovascular outcome events were collected during follow-up until 2020. Participants were categorized into Q1–Q4 groups based on baseline WWI quartiles. Multivariable log-binomial regression models were constructed to assess the association between WWI and CVD， while restricted cubic splines were employed to evaluate potential nonlinear relationships. Sensitivity analyses were conducted to verify the robustness of the findings. ResultsFrom 2011 to 2015， the weighted mean WWI among Chinese middle-aged and older adults remained generally stable （2011： 11.17±1.68； 2013： 11.28±1.35； 2015： 11.24±1.59； P for trend <0.05）. During the longitudinal follow-up， 1 784 incident CVD cases were documented. After multivariable adjustment， each unit increase in WWI was associated with a 17% increased risk of CVD （RR： 1.17， 95%CI： 1.10-1.24）. Compared with the Q1 group， the risk of CVD in the Q2， Q3， and Q4 groups increased by 23% （RR： 1.23， 95% CI： 1.07-1.40）， 27% （RR： 1.27， 95% CI： 1.11-1.44）， and 40% （RR： 1.40， 95% CI： 1.22-1.60）， respectively. A significant linear trend was observed between the increasing WWI and elevated CVD risk （P for trend <0.001）. Subgroup analysis revealed a stronger association in participants aged 45-60 years （P for interaction <0.05）. The results of sensitivity analysis were consistent with the main research results. ConclusionsThe overall trend of WWI level in the middle-aged and elderly population in China is stable from 2011 to 2015. The higher level of WWI is associated with an increased risk of CVD， suggesting that WWI may be used as a simple and effective indicator to evaluate the risk of cardiovascular metabolism in middle-aged and elderly people.

ObjectiveTo investigate the mechanism of Si Junzitang in treating liver injury in rats with spleen Qi deficiency syndrome based on transcriptomics and to experimentally verify its effects. MethodsSixty male SD rats were randomly divided into blank group， model group， low-dose Si Junzitang （6 g·kg^-1·d^-1）， medium-dose Si Junzitang group （12 g·kg^-1·d^-1）， high-dose Si Junzitang group （24 g·kg^-1·d^-1）， and natural recovery group， with 10 rats in each group. A composite multifactorial modeling method （forced swimming + intragastric administration of Xiao Chengqitang + irregular diet） was used to establish a spleen Qi deficiency model. After 30 days of continuous intervention， body weight and 3-hour food intake were measured， and macroscopic symptom scores for spleen Qi deficiency syndrome were evaluated. Serum levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT） in each group were detected， and hematoxylin and eosin （HE） staining was used to observe histopathological changes in liver tissue. Transcriptome sequencing （RNA-Seq） was used to identify differentially expressed genes （DEGs） among the blank， model， and high-dose Si Junzitang groups. Gene ontology（GO） and Kyoto encyclopedia of genes and genome（KEGG） enrichment analyses were performed on the DEGs. Immunofluorescence （IF） and Western blot were used to detect NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein （ASC）， Caspase-1， and the N-terminal domain of gasdermin D （GSDMD-N）. Immunohistochemistry （IHC） was used to detect the expression of downstream inflammatory cytokines interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and interleukin-18 （IL-18）. ResultsCompared with the blank group， the model group showed significantly reduced body weight and 3-hour food intake， significantly increased macroscopic symptom scores， and elevated serum AST and ALT levels （P<0.01）， with mild inflammatory liver injury observed histologically. Compared with the model group， Si Junzitang at all doses significantly improved these parameters and alleviated liver injury in a dose-dependent manner （P<0.05，P<0.01）. RNA-Seq analysis revealed 1 254 DEGs between the blank and model groups， and 842 DEGs between the model and high-dose Si Junzitang groups. GO and KEGG enrichment analyses indicated that the NOD-like receptor signaling pathway was activated in liver injury associated with spleen Qi deficiency， suggesting that the NLRP3 inflammasome may be a key target. Results from IF， IHC， and Westernblot showed that compared with the blank group， the expression of NLRP3， ASC， Caspase-1， GSDMD-N， and the downstream inflammatory cytokines IL-1β， IL-6， and IL-18 were significantly increased in the model group （P<0.01）， while these levels were markedly decreased in the high-dose Si Junzitang group （P<0.01）. ConclusionSi Junzitang effectively improves mild inflammatory liver injury in rats with spleen Qi deficiency syndrome in a dose-dependent manner. Its mechanism may be associated with inhibition of the NLRP3/ASC/Caspase-1 signaling pathway， downregulation of the pyroptosis executioner protein GSDMD-N， and reduction of pyroptosis-related inflammatory cytokine release.

OBJECTIVE: To investigate the effect of moxibustion on central insulin resistance related proteins of the rats suffering from diabetic cognitive decline, and analyze the underlying mechanism of moxibustion for cognition improvement. METHODS: Using the intraperitoneal injection of STZ combined with a high-fat diet, the rat model of diabetic cognitive decline were prepared. Twenty successfully-modeled rats were assigned randomly into a model group and a moxibustion group, 10 rats in each one. Besides, a blank group was set up with 10 rats collected. In the moxibustion group, suspending moxibustion was applied to "Baihui" (GV20), "Shenting" (GV24) and "Dazhui" (GV14) at the same time, 20 min in each intervention, once a day, and 6 interventions were delivered weekly and the duration of treatment was consecutive 4 weeks. The random blood glucose was measured using glucometer, and the learning-memory ability was detected by water maze test. HE staining was used to observe the morphology of neurons in the hippocampal tissue, real-time PCR assay was to detect mRNA expression of insulin receptor substrate 1 (IRS1), phosphatidylinositol 3-kinase (PI3K) and protein kinase B (AKT) in the hippocampal tissue. The Western blot method was employed to detect the protein expression of IRS1, PI3K, AKT, phosphorylated IRS1 (p-IRS1), phosphorylated PI3K (p-PI3K) and phosphorylated AKT (p-AKT) in the hippocampal tissue, and the ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT was calculated separately. The immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT was measured using immunofluorescence. RESULTS: Compared with the blank group, the rats of the model group exhibited higher random blood glucose (P<0.001), longer escape latency (P<0.001), severe pathological damage in the hippocampus, lower mRNA expression of IRS1, PI3K, and AKT (P<0.001), reduced ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT (P<0.001), and declined immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT in the hippocampal tissue (P<0.001). In comparison with the model group, for the rats of the moxibustion group, the random blood glucose decreased (P<0.05), the escape latency was shortened (P<0.01), the hippocampal pathological damage was attenuated, the mRNA expression of IRS1, PI3K and AKT increased (P<0.01), the ratio of p-IRS1/IRS1, p-PI3K/PI3K and p-AKT/AKT was elevated (P<0.01, P<0.05), and the immunofluorescence intensity of p-IRS1, p-PI3K, and p-AKT in the hippocampal tissue was strengthened (P<0.01, P<0.05). CONCLUSION In diabetic rats experiencing cognitive decline, moxibustion can enhance the learning-memory ability, which may be attributed to modulating the protein expression of IRS1, PI3K, and AKT, and their phosphorylation, activating insulin signal transduction, and reducing central insulin resistance.

OBJECTIVE: To investigate the effects of Huayu Tongluo (transforming stasis and unblocking collaterals) moxibustion on cognitive function and insulin resistance in patients with type 2 diabetes mellitus (T2DM) and cognitive decline. METHODS: Ninety patients with T2DM and cognitive decline were randomly divided into a moxibustion group (n=45, 3 cases dropped out, 2 cases were eliminated) and a waiting moxibustion group (n=45, 2 cases dropped out). Both groups received routine hypoglycemic treatment for 12 weeks. The moxibustion group additionally received Huayu Tongluo moxibustion at Baihui (GV20), Shenting (GV24), and Dazhui (GV14). Pressing moxibustion was applied to Baihui (GV20) for 20 min, while suspended moxibustion was applied to Shenting (GV24) and Dazhui (GV14) for 20 min each. Treatments of moxibustion were administered every other day (three times per week) for 12 weeks. All patients were followed up for 12 weeks, during which their original hypoglycemic medication regimen was maintained. Before treatment, after 12 weeks of treatment, and at the 12-week follow-up, the scores of Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE), Addenbrooke's cognitive examination Ⅲ (ACE-Ⅲ), symbol digit modalities test (SDMT), and Athens insomnia scale (AIS) and the insulin resistance index (HOMA-IR) were observed in the two groups. RESULTS: Compared with before treatment, the MoCA scores, MMSE scores, ACE-Ⅲ subscale scores (attention, memory, language fluency, language, visuospatial ability) and total scores, and SDMT scores were increased (P<0.01), while the AIS scores were decreased (P<0.05) in the moxibustion group after treatment and at follow-up. Compared with before treatment, the MMSE score, ACE-Ⅲ subscale scores (memory, attention) and total score after treatment, as well as the ACE-Ⅲ subscale scores (language, memory, attention) and total score, and SDMT score at follow-up were increased (P<0.05, P<0.01) in the waiting moxibustion group. Compared with before treatment, HOMA-IR was decreased in both groups after treatment and at follow-up (P<0.01). At follow-up, ACE-Ⅲ subscale scores (attention, memory), and the total score in the moxibustion group were lower than those after treatment (P<0.05, P<0.01), and the ACE-Ⅲ language subscale score, total ACE-Ⅲ score, and SDMT score in the waiting moxibustion group were higher than those after treatment (P<0.01, P<0.05). After treatment and at follow-up, compared with the waiting moxibustion group, the moxibustion group had higher MoCA scores, MMSE scores, SDMT scores, ACE-Ⅲ subscale scores (attention, memory, language fluency) and total scores (P<0.05, P<0.01), and lower HOMA-IR (P<0.05). CONCLUSION Huayu Tongluo moxibustion can effectively improve cognitive function in patients with T2DM and cognitive decline. This improvement may be associated with the reduction in insulin resistance.

The inhibition of cyclin-dependent kinases (CDKs) is considered a promising strategy for cancer treatment due to their role in cell cycle regulation. However, CDK inhibitors with no selectivity among CDK families have not been approved. A CDK inhibitor with high selectivity for CDK4/6 exhibited significant treatment effects on breast cancer and has become a heavy bomb on the market. Subsequently, resistance gradually decreased the efficacy of selective CDK4/6 inhibitors in breast cancer treatment. In this review, we first introduce the development of selective CDK4/6 inhibitors and then explain the role of CDK2 activation in inducing resistance to CDK4/6 inhibitors. Moreover, we focused on the development of CDK2/4/6 inhibitors and selective CDK2 inhibitors, which will aid in the discovery of novel CDK inhibitors targeting the cell cycle in the future.
