Both hyperlipidemic acute pancreatitis and fatty liver disease are associated with lipid metabolism disorders and are commonly comorbid with each other in clinical practice. The pathogenesis of such comorbidity involves the interaction between multiple factors such as hypertriglyceridemia, metabolic syndrome, obesity, and insulin resistance, and these factors may form a vicious cycle and jointly promote disease progression. In clinical practice, hyperlipidemic acute pancreatitis is characterized by severe disease conditions, a high incidence rate of complications, a high mortality rate, and a tendency for recurrence, and it can easily lead to multi-organ damage and even multiple organ failure without timely treatment, posing a serious threat to the life of patients. Starting from the various signaling pathways associated with hyperlipidemic acute pancreatitis comorbid with fatty liver disease, this article discusses the potential molecular mechanisms of synergistic pathogenesis between hyperlipidemic acute pancreatitis and fatty liver disease, so as to provide a reference for the early prevention and treatment of such comorbidity.

To summarize the distribution characteristics of human papillomavirus(HPV) infection types in patients with cervical squamous intraepithelial lesion(SIL) and cervical cancer(CC), and to explore the impact of HPV vaccination, HPV infection types, and general clinical data on different grades of cervical lesions. Clinical data of women attending the gynecological colposcopy clinic of Shenzhen People's Hospital from January 2020 to December 2023 were retrospectively collected. Patients with HPV genotyping records and histopathologically diagnosed SIL or CC were included and divided into three groups based on pathological results: low-grade squamous intraepithelial lesion(LSIL) group, high-grade squamous intraepithelial lesion(HSIL) group, and CC group. The distribution of high-risk HPV subtypes was analyzed among the three groups, and multivariate Logistic regression was used to identify influencing factors for high-grade cervical lesions. A total of 4162 patients were included, comprising 4057 cervical SIL patients(3317 LSIL and 740 HSIL) and 105 CC patients. The overall mean age was(39.9±11.2) years. The HPV infection rate was 95.1%(3959/4162), and 25.0%(1040/4162) of patients had received HPV vaccination. Among high-risk HPV infections, HPV 52, HPV 16, HPV 58, and HPV 18 were the most common subtypes. HPV 52 had the highest infection rate in the LSIL group(27.6%), while HPV 16 was the most prevalent in the HSIL group(45.3%) and CC group(64.9%). Multivariate Logistic regression analysis showed that HPV vaccination( HPV infection is common in patients with SIL and CC, but the distribution of high-risk HPV subtypes varies among different grades of cervical lesions. It is recommended to strengthen cervical cancer screening and monitoring of key high-risk HPV infections in older and multiparous women in Shenzhen, and to continue promoting HPV vaccination.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Septic shock is the primary cause of mortality in sepsis, with its core pathophysiological mechanism being severe ischemia and hypoxia in critical units—composed of microcirculation and the mitochondria of functional cells—resulting from disruptions in blood flow and oxygen flow following a dysregulated host response. Due to the systemically convergent yet clinically heterogeneous nature of the host response, current understanding and management strategies for hemodynamics remain inconsistent, often leading to inadequate resuscitation or overtreatment. To improve the quality of care, based on a systematic review of the "blood flow-oxygen flow" theory, an expert panel emphasizes reevaluating septic shock from an integrated perspective of blood flow and oxygen flow, and has formulated the

ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and the severity of intrauterine adhesions (IUA). MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions (TCRA) from December 2019 to March 2025. Based on the American Fertility Society (AFS) classification, patients were divided into mild (n=61), moderate (n=225), and severe (n=94) groups. NLR, PLR, and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR, PLR, and SII were significantly higher in the severe IUA group compared to the mild group (P<0.05), with SII showing the strongest predictive ability (OR=1.004, P=0.001). The number of intrauterine procedures was an independent risk factor (OR=1.27/level, P=0.016). The predictive model [Logit(P)=-0.676+0.241×operation times+0.004×SII] effectively identified severe IUA cases. ConclusionInflammatory markers (particularly SII) are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

ObjectiveTaking Aurantii Fructus Immaturus juice(AFI)-processed Atractylodis Macrocephalae Rhizoma(AMR) as an example, this study aims to systematically compare the volatile and non-volatile components of AMR and its processed products, investigate the key differential components, evaluate their anti-inflammatory activities, and elucidate the synergistic mechanism of processing. MethodsThe chemical compositions of volatile and non-volatile components in AMR and AFI-processed AMR were systematically characterized using gas chromatography-mass spectrometry(GC-MS) and ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS), with relative mass fractions and response values determined separately. Volatile components were identified through searches in the National Institute of Standards and Technology(NIST)17 database, comparison with retention index(RI) and fragmentation pattern matching. Non-volatile components were identified by searching Waters Traditional Chinese Medicine (TCM) spectral library, in conjunction with PubChem and MassBank, characteristic fragmentation patterns and response values were also used to support identification. Differential components were screened using principal component analysis(PCA), orthogonal partial least squares-discriminant analysis(OPLS-DA), with variable importance in the projection(VIP) value >1. Components with high log2fold change(FC) among major differential groups were selected as those exhibiting significant changes before and after processing. The anti-inflammatory activity of the differential compounds was evaluated by assessing their effects on nitric oxide(NO) production in a lipopolysaccharide(LPS)-induced RAW264.7 macrophage model. Enzyme-linked immunosorbent assay(ELISA) was used to detect the effects of the differential components on tumor necrosis factor(TNF)-α, interleukin(IL)-1β, IL-6, and monocyte chemotactic protein(MCP)-1 levels, and immunofluorescence(IF) was employed to assess their effects on nuclear transcription factor(NF)-κB p65 translocation, thereby elucidating the underlying molecular mechanisms. ResultsA total of 36 compounds were identified in the volatile components of AMR and AFI-processed AMR, among which, sesquiterpenes and monoterpenes were significantly increased after processing. In the non-volatile components, 36 compounds were identified, and the main differential components were flavonoids, sesquiterpenoids, and triterpenoids. Flavonoids were the primary differential components distinguishing AMR from its processed products, representing compounds directly introduced during processing. Five compounds, including atractylenolide Ⅲ, tangeritin, nobiletin, hesperidin and narirutin, were selected as representatives of three classes based on their most prominent differential expression among different compound types for subsequent anti-inflammatory activity studies. The results showed that 100 μmol·L-1 tangerine and narirutin could significantly inhibit LPS-induced NO production(P<0.01) in a concentration-dependent manner. Tangeritin was able to significantly inhibit the levels of TNF-α and MCP-1 secreted by RAW264.7(P<0.05), while narirutin significantly inhibited the levels of TNF-α, IL-1β, MCP-1 and IL-6(P<0.01). IF revealed that both tangeritin and narirutin significantly blocked the translocation of NF-κB p65 from the cytoplasm to the nucleus. ConclusionAFI-processed AMR significantly alters the chemical composition profile of AMR, and the newly introduced flavonoid components during processing may be key to its enhanced anti-inflammatory effects.
6.Good patients: the logical direction of patients’ moral responsibilities
Chinese Medical Ethics 2026;39(1):94-99
The construction of a harmonious doctor-patient relationship requires both doctors and patients to bear the corresponding moral responsibilities. Patients’ moral responsibilities refer to the duties that patients should take action and bear the corresponding good and bad consequences to restore their physical or mental health, as well as the good qualities that help patients adapt to and integrate into their patient roles and pursue excellence. The logical direction of patients’ moral responsibilities represents the practical vision and value orientation of patients’ moral responsibility research. Healthy bodies are the direct goal of patients’ moral responsibilities, harmonious interpersonal relationships serve as the basic goal, and good lives represent the core goal. The logical direction of patients’ moral responsibilities returns to the human being, focusing on profound care for real patients and ideal construction. Healthy bodies, harmonious interpersonal relationships, and good lives collectively achieve “good patients”, who are the logical direction of patients’ moral responsibilities.

To compare gait parameters during single-task and dual-task walking in older adults, and to examine differences in dual-task costs between individuals with high versus low balance abilities under different task conditions. From November to December 2024, community-dwelling older adults were recruited through Hebei Province's national physical fitness monitoring network across multiple communities in Shijiazhuang and Xiong'an New Area. An inertial sensor-based gait analysis system was used to collect spatiotemporal gait parameters during three conditions: single-task walking, motor dual-task walking (simultaneous carrying task), and cognitive dual-task walking (serial subtraction task). Participants were stratified into high-balance and low-balance groups based on median eyes-closed single-leg stance duration (cut-off: 18.40 seconds). Dual-task costs (DTC) were calculated and compared between groups. The study included 133 eligible participants[30 male, 103 female; mean age (66.95±4.75) years]. The low-balance group 66 participants, and the high-balance group 67 participants. Compared to single-task walking, motor dual-task conditions significantly increased stride time and double support phase duration (all While dual-task conditions generally impair gait parameters in older adults, individuals with higher balance abilities maintain more stable gait patterns during motor dual-tasks, demonstrating greater resilience to interference. These findings highlight the importance of balance capacity in preserving functional mobility during daily multitasking activities.

To investigate the prevalence and associated factors of fall risk among Chinese older adults, and to examine the roles of urban-rural differences, regional disparities, physical health status, and psychosocial factors in falls among this population, thereby providing evidence for tailored fall prevention strategies. Using data from the 2024 National Routine Physical Fitness Surveillance, a multi-stage stratified sampling method was employed to recruit community-dwelling older adults aged 60-79 years across China. High fall-risk individuals were identified using the Chinese version of the self-rated fall risk questionnaire, while demographic, physical health, and psychological indicators were collected via questionnaires and objective measurements. A generalized linear mixed model (GLMM) with province as a random effect was used to analyze fall risk factors. Among 7000 eligible participants (male: 44.2%, female: 55.8%), the sample comprised 2124 (60-64 years), 2014 (65-69 years), 1660 (70-74 years), and 1202 (75-79 years) individuals, with 58.4% from rural and 41.6% from urban areas. A total of 733(10.5%) were identified as high fall-risk, with higher prevalence among females (10.9%), urban residents (11.5%), and the oldest age group (75-79 years: 12.4%). GLMM random-intercept logistic regression revealed that advanced age ( The prevalence of high fall risk among Chinese community-dwelling older adults aged 60-79 years is 10.5%. Fall risk demonstrates significant associations with multiple factors including muscle strength, movement patterns, sleep quality, and social support. Strategies enhancing grip strength, promoting regular exercise and high-intensity leisure activities, improving sleep quality, fostering spousal support, and boosting life satisfaction may substantially reduce fall risk in this population.

Based on the data from the 5th National Physical Fitness Surveillance in China, this study aimed to explore the relationship between abnormal body weight and physical fitness levels in older adults. The study included adults aged 60-79 years from the 5th National Physical Fitness Surveillance database. Body weight was categorized into four groups—underweight, normal weight, overweight, and obesity—based on body mass index (BMI), with underweight, overweight, and obesity classified as abnormal weight. Physical fitness indicators such as cardiorespiratory endurance (number of 2-minute high-knee steps), lower limb muscle strength (number of 30-second chair stands), flexibility (sit-and-reach test), balance ability (eyes-closed single-leg stance time), and reaction ability (choice reaction time) were collected. Each physical fitness indicator was divided into four levels (excellent, good, pass, and fail) based on quartile cutoffs. After adjusting for demographic factors (including age, sex, urban/rural residence, education level, pre-retirement occupation, marital status, exercise habits, smoking, sleep quality, and self-rated fitness), binary Logistic regression was used to analyze the association between physical fitness indicators and abnormal weight. A total of 39 927 older adults aged 60-79 years were included, comprising 19 777 men (49.5%) and 20 150 women (50.5%), with a mean age of 69.2±5.6 years. The prevalence rates of underweight, overweight, and obesity were 2.3%, 41.8%, and 16.7%, respectively, with underweight prevalence significantly increasing with age ( Chinese older adults aged 60-79 years face a dual burden of underweight and overweight/obesity. Poor cardiorespiratory endurance and muscle strength (in women) are significantly associated with abnormal weight. Maintaining good cardiorespiratory endurance and muscle strength may help improve abnormal weight status in older adults.

To explore the dose-response correlation between appendicular skeletal muscle index (ASMI) and muscle strength in older adults. This study included adults aged 60-79 years from the 2024 National Routine Physical Fitness Surveillance database. ASMI was used to assess muscle mass, while handgrip strength and 30-second chair stand test (30-s CST) repetitions were employed to evaluate muscle strength. Linear regression analyses, adjusted for age and body mass index (BMI), were performed to examine the associations between ASMI and handgrip strength/30-s CST. Additionally, restricted cubic spline (RCS) models were applied for dose-response analysis. A total of 68 038 older adults (56.3% female, mean age 68.0±5.4 years) were included. Males exhibited significantly higher handgrip strength(33.6± 7.8 kg s Muscle mass and strength are significantly positively correlated in older adults. Personalized muscle health interventions should be considered to reduce the rate of decline in muscle strength, when ASMI falls below 13.55 kg/m2 in men or 11.25 kg/m2 in women.
