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.
5.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.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis (AS). MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group, low drug-containing serum group, medium drug-containing serum group, high drug-containing serum group, and positive drug group. After drug intervention, cell proliferation was measured using the cell counting kit-8 (CCK-8) assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase (ALP) activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin (OCN), osteopontin (OPN), and runt-related transcription factor 2 (Runx2) was detected by Western blot. The mRNA expression levels of Wnt5a, β-catenin, and Dickkopf-1 (DKK-1) were measured by real-time quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with the blank group, each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression (P<0.01). Compared with the blank group, the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression (P<0.05). The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression (P<0.05, P<0.01), with the positive drug group showing the most pronounced effect (P<0.01). The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression (P<0.01). Compared with the blank group, the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins (P<0.05, P<0.01), while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN, OPN, and Runx2 proteins (P<0.05, P<0.01). ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts, thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression, further inhibiting the transcription of downstream target genes.

The pathological changes of myocardial infarction (MI) are mainly characterized by progressive myocardial ischemic necrosis, decline in cardiac diastolic function, thinning of the ventricular wall, and enlargement of the ventricles. The clinical manifestations include myocardial ischemia, heart failure, arrhythmia, shock, and even sudden cardiac death, rendering MI one of the most perilous cardiovascular diseases. Currently, the clinical treatment for MI primarily involves interventional procedures and drug therapy. However, due to their significant side effects and high complication rates associated with these treatments, they fail to ensure a satisfactory quality of life and long-term prognosis for patients. On the other hand, traditional Chinese medicine has demonstrated remarkable potential in improving patient prognosis while reducing side effects. Research has elucidated that various signaling pathways such as nuclear transcription factor-κB (NF-κB), adenosine 5̒-monophosphate-activated protein kinase (AMPK), transforming growth factor-β (TGF-β)/Smads, mitogen-activated protein kinase (MAPK), Wnt/β-catenin (β-catenin), and phosphatidylinositol 3-kinase (PI3K)/protein kinase B(Akt) play crucial roles in regulating the occurrence and development of MI. Effectively modulating these signaling pathways through its therapeutic interventions, traditional Chinese medicine can enhance MI management by inhibiting apoptosis, providing anti-inflammatory properties, alleviating oxidative stress levels, and resisting myocardial ischemia. Due to its notable efficacy and favorable safety, it has become an area of focus in clinical practice.

Chronic obstructive pulmonary disease (COPD) is a common disease with a high incidence and mortality rate in the world. It is characterized by chronic inflammation and structural obstruction and is not completely reversible which will lead to shortness of breath caused by air retention and physical exertion. Traditional Chinese medicine proposes the concept of "lung collaterals", which refers to the collateral vessels scattered throughout the lungs and lung system. The lung collaterals include the pulse collaterals and Qi collaterals. The blood circulation in the pulse collaterals belongs to Yin, distributed internally along the way. The Qi circulation in the Qi collateral belongs to Yang and is distributed externally. In western medicine, the pulse collaterals have an identity with large, medium, and small blood vessels, microvessels, and especially microcirculation. The Qi collateral encompasses systems such as the nervous, endocrine, and immune system. Pulmonary microvascular endothelial cells (HPMECs) are an important component of the pulmonary microvascular endothelium. Recent studies have found that HPMECs are the main damaged cells in the pathogenesis of COPD, mediating the occurrence and development of COPD. Traditional Chinese medicine can regulate HPMECs to treat COPD through multiple components, targets, and pathways, and has the advantage of reducing western medicine resistance and many side effects. Based on the "lung collateral theory", this paper focused on HPMECs, and elaborated on the new connotation of traditional Chinese medicine in protecting HPMECs to treat COPD, aiming to provide new insights for the clinical treatment of COPD by protecting HPMECs.

10.Association of outdoor activity level and myopia among children and adolescents in Shanghai
Chinese Journal of School Health 2025;46(1):18-23
Objective:
To analyze the status of outdoor activities on weekends among children and adolescents of different educational stages in Shanghai and their impact on myopia, so as to provide a basis for formulating more specific prevention and control protocol of myopia.
Methods:
From September to October 2022, a stratified cluster random sampling method was employed to select 84 schools (27 kindergartens, 21 primary schools, 15 junior high schools and 21 high schools) across Shanghai, enrolling a total of 28 654 children and adolescents aged 4 to 18 for the study. Ophthalmic examinations were conducted to ascertain the prevalence of myopia among children and adolescents. Additionally, a questionnaire survey was administered to collect data on outdoor activity duration and associated factors. Multivariate Logistic regression analysis was utilized to investigate the associated factors of outdoor activity levels on weekends.
Results:
The overall myopia detection rate among children and adolescents was 58.4%, with a higher rate observed in girls (59.2%) compared to boys (57.6%). The myopia detection rates for children and adolescents with an average daily outdoor activity duration of ≥2 h and <2 h on weekends were 54.6% and 68.8%, and the differences were statistically significant ( χ 2=8.12,460.89, P <0.01). Multivariable Logistic regression analysis revealed that girls ( OR =0.80), those with a myopic parent ( OR =0.68), schools from urban districts ( OR =0.72), higher education stages (primary school: OR =0.65, junior high school: OR =0.24, high school: OR =0.14) and spending≥2 h/d on homework during weekends ( OR =0.57) among children and adolescents were less likely to engage in outdoor activities for ≥2 h on weekends ( P <0.01). After incorporating gender, parental myopia status, educational stage, school location, average daily duration on weekends for spending on homework, electronic product usage and outdoor activities as dependent variables in a multivariate Logistic regression analysis, the results showed that children and adolescents with an average outdoor activity duration for ≥2 h on weekends had a lower risk of myopia ( OR =0.86, P < 0.01).
Conclusions
The level of outdoor activity among children and adolescents on weekends needs to be improved. Outdoor activities on weekends is an associated factor for myopia among children and adolescents. Particularly, girls, those with myopic parents, schools from urban districts, and spending long hours on homework during weekends among children and adolescents require increased attention.
