ObjectiveTo elucidate the efficacy connotation of Shudi Qiangjin pills (SQP) against liver and kidney deficiency in steroid-induced osteonecrosis of femoral head (SONFH) from the perspective of the "disease-syndrome-formula" association and to clarify the underlying mechanisms based on in vivo and in vitro experiment validation. MethodsThe chemical components and the corresponding putative targets of SQP were collected from the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0, the Encyclopedia of Traditional Chinese Medicine (ETCM) v2.0, and HERB databases. The SONFH-related genes were identified based on the differential expression profiles of peripheral blood of patients with SONFH compared to the healthy volunteers, and the disease phenotype-related targets were collected from the TCMIP v2.0 database. Then, the interaction network of "SONFH-related genes and candidate targets of SQP" was constructed based on "gene-gene interaction information", and the major network targets were screened by calculating the topological characteristic values of the network followed by the functional mining according to the Kyoto Encyclopedia of Genes and Genomes (KEGG) database and the SoFDA database. After that, the SONFH rat model was prepared by lipopolysaccharide combined with methylprednisolone injection, and 2.5, 5, 7.5 g·kg-1 SQP (once per day, equivalent to 1, 2, and 3 times the clinical equivalent dose, respectively) or 7.3×10-3 g·kg-1 of alendronate sodium (ALS, once per week, equivalent to the clinical equivalent dose) was given for 8 weeks. The effect characteristics of SQP and ALS in the treatment of SONFH were evaluated by micro-computed tomography scanning, hematoxylin and eosin staining, alkaline phosphatase (ALP) staining, immunohistochemical staining, enzyme-linked immunosorbent assay, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)staining, and a comparative efficacy analysis was conducted with ALS. In addition, SONFH cell models were prepared by dexamethasone stimulation of osteoblasts, and the intervention was carried out with the medicated serum of SQP at the aforementioned three doses. Cell counting kit-8, ALP staining, ALP activity assay, alizarin red staining, and flow cytometry were employed to investigate the regulatory effect of SQP on osteoblasts. The expression levels of osteogenesis-related proteins and key factors of the target signaling axis were detected by quantitative real-time polymerase chain reaction and Western blot. ResultsThe network analysis results demonstrated that the candidate targets of SQP primarily exerted their therapeutic effects through key signaling pathways, including phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt), lipid metabolism and atherosclerosis, prolactin, chemokines, and neurotrophic factors pathways. These pathways were significantly involved in critical biological processes such as muscle and bone metabolism and the regulation of the "neuro-endocrine-immune" network, thereby addressing both modern medical symptoms (e.g., delayed skeletal maturation and recurrent fractures) and traditional Chinese medicine (TCM) symptoms (e.g., fatigue, aversion to cold, cold limbs, and pain in the limbs and joints in patients with SONFH characterized by liver and kidney deficiency syndrome. Among these pathways, the PI3K/Akt signaling pathway exhibited the highest degree of enrichment. The in vivo experimental results demonstrated that starting from the 4th week after modeling, the modeling group exhibited a significant reduction in body weight compared to the control group (P<0.05). After six weeks of treatment, all dosage groups of SQP showed significantly higher body weights compared to the model group (P<0.01). Compared with the normal group, the model group exhibited significant decreases in bone mineral density (BMD), bone volume fraction (BV/TV), trabecular number (Tb.N), osteocalcin (OCN), alkaline phosphatase (ALP) levels in femoral head tissue, and serum bone-specific alkaline phosphatase (BALP) (P<0.01), along with significant increases in trabecular separation (Tb.Sp), empty lacunae rate in tissue, and apoptosis rate (P<0.01). In comparison to the model group, the SQP intervention groups showed significant improvements in BMD, BV/TV and Tb.N (P<0.01), significant reductions in Tb.Sp, empty lacunae rate and apoptosis rate (P<0.05), and significant increases in protein levels of OCN and ALP as well as BALP content (P<0.05). The in vitro experimental results revealed that all dosage groups of SQP medicated serum showed no toxic effects on osteoblast. Compared with the normal group, the model group displayed significant suppression of osteoblast proliferation activity, ALP activity, and calcified nodule formation rate (P<0.01), significant decreases in mRNA transcription levels of OCN and Runt-related transcription factor 2 (RUNX2) (P<0.01), significant reductions in protein content of osteopontin (OPN), typeⅠ collagen (ColⅠ)A1, B-cell lymphoma-2 (Bcl-2), PI3K, and phosphorylated (p)-Akt (P<0.01), and a significant increase in apoptosis rate (P<0.01). Compared with the model group, the SQP medicated serum intervention groups exhibited significant increases in proliferation activity, ALP activity, calcified nodule formation rate, mRNA transcription levels of OCN and RUNX2, and protein content of OPN, ColⅠA1, Bcl-2, PI3K, and p-Akt (P<0.05), along with a significant decrease in apoptosis rate (P<0.01). ConclusionSQP can effectively reduce the disease severity of SONFH with liver and kidney deficiency syndrome and improve bone microstructure, with the therapeutic effects exhibiting a dose-dependent manner. The mechanism may be related to its regulation of key processes such as muscle and bone metabolism and the correction of imbalances in the "neuro-endocrine-immune" network, thereby promoting osteoblast differentiation and inhibiting osteoblast apoptosis. The PI3K/Akt signaling axis is likely one of the key pathways through which this formula exerts its effects.

ObjectiveTo observe the clinical efficacy of Sanren Runchang formula in treating constipation-predominant irritable bowel syndrome (IBS-C) by regulating the brain-gut axis and the effects of the formula on serum levels of 5-hydroxytryptamine (5-HT), vasoactive intestinal peptide (VIP), and substance P (SP). MethodsA randomized controlled design was adopted, and 72 IBS-C patients meeting Rome Ⅳ criteria were randomized into observation and control groups (36 cases).The observation group received Sanren Runchang formula granules twice daily, and the control group received lactulose oral solution daily for 4 weeks. IBS Symptom Severity Scale (IBS-SSS), IBS Quality of Life Scale (IBS-QOL), and Bristol Stool Form Scale (BSFS) were used to assess clinical symptoms, and bowel movement frequency was recorded. The Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were employed to evaluate psychological status. ELISA was employed to measure the serum levels of 5-HT, VIP, and SP. ResultsThe total response rate in the observation group was 91.67% (33/36), which was higher than that (77.78%, 28/36) in the control group (χ2=4.50, P<0.05). After treatment, both groups showed increased defecation frequency and BSFS scores, decreased IBS-SSS total score, abdominal pain and bloating scores, IBS-QOL health anxiety, anxiety, food avoidance, and behavioral disorders scores, SAS and SDS scores, serum 5-HT and VIP levels, and increased SP levels (P<0.05, P<0.01). Moreover, the observation group showed more significant changes in the indicators above than the control group (P<0.05, P<0.01). The SP level showed no significant difference between the two groups. During the 4-week follow-up, the recurrence rate was 5.88% in the observation group and 31.25% in the control group. No adverse events occurred in observation group, and 2 cases of mild diarrhea occurred in the control group. ConclusionSanren Runchang formula demonstrated definitive efficacy in alleviating gastrointestinal symptoms and improving the psychological status and quality of life in IBS-C patients, with a low recurrence rate. The formula can regulate serum levels of neurotransmitters such as 5-HT and VIP, suggesting its potential regulatory effect on the brain-gut axis through modulating neurotransmitters and neuropeptides. However, its complete mechanism of action requires further investigation through detection of additional brain-gut axis-related biomarkers.

Adipose tissue is a critical energy reservoir in animals and humans, with multifaceted roles in endocrine regulation, immune response, and providing mechanical protection. Based on anatomical location and functional characteristics, adipose tissue can be categorized into distinct types, including white adipose tissue (WAT), brown adipose tissue (BAT), beige adipose tissue, and pink adipose tissue. Traditionally, adipose tissue research has centered on its morphological and functional properties as a whole. However, with the advent of single-cell transcriptomics, a new level of complexity in adipose tissue has been unveiled, showing that even under identical conditions, cells of the same type may exhibit significant variation in morphology, structure, function, and gene expression——phenomena collectively referred to as cellular heterogeneity. Single-cell transcriptomics, including techniques like single-cell RNA sequencing (scRNA-seq) and single-nucleus RNA sequencing (snRNA-seq), enables in-depth analysis of the diversity and heterogeneity of adipocytes at the single-cell level. This high-resolution approach has not only deepened our understanding of adipocyte functionality but also facilitated the discovery of previously unidentified cell types and gene expression patterns that may play key roles in adipose tissue function. This review delves into the latest advances in the application of single-cell transcriptomics in elucidating the heterogeneity and diversity within adipose tissue, highlighting how these findings have redefined the understanding of cell subpopulations within different adipose depots. Moreover, the review explores how single-cell transcriptomic technologies have enabled the study of cellular communication pathways and differentiation trajectories among adipose cell subgroups. By mapping these interactions and differentiation processes, researchers gain insights into how distinct cellular subpopulations coordinate within adipose tissues, which is crucial for maintaining tissue homeostasis and function. Understanding these mechanisms is essential, as dysregulation in adipose cell interactions and differentiation underlies a range of metabolic disorders, including obesity and diabetes mellitus type 2. Furthermore, single-cell transcriptomics holds promising implications for identifying therapeutic targets; by pinpointing specific cell types and gene pathways involved in adipose tissue dysfunction, these technologies pave the way for developing targeted interventions aimed at modulating specific adipose subpopulations. In summary, this review provides a comprehensive analysis of the role of single-cell transcriptomic technologies in uncovering the heterogeneity and functional diversity of adipose tissues.

To identify and validate the clinical phenotypes of patients with sepsis in the intensive care unit(ICU). We applied unsupervised machine learning algorithms (K-means clusteringand hierarchical clustering) to identify the phenotypes of sepsis patients in the Medical Information Mart for Intensive Care Ⅳ (MIMIC-Ⅳ) 2.2 database, based on 89 clinical features including demographic characteristics, laboratory indicators and treatment measures on the first day in ICU. Then, supervised machine learning algorithms (lightweight gradient boosting machine) were used for the prediction of the patient's phenotypes, and were further combined with SHAP (Shapely Additive eXplanations) for the identification of important features. Finally, traditional statistical methods were used to validate the differences in clinical characteristics and clinical outcomes among the phenotypes. We identified three phenotypes in 22 517 sepsis patients. The phenotype 1 patients had the highest risk of death (28-day mortality of 46.4%), dominated by abnormal renal function and elevated disease severity scores, while the phenotype 3 patients had the lowest risk of death (28-day mortality of 11.2%), and the best neurological function score. Using interpretable machine learning, we identified six features (all the worst value on the first day) that showed good performance in phenotypic identification(AUC≥0.89) and phenotypic prognostic prediction (AUC≥0.74): anion gap, blood urea nitrogen, creatinine, Glasgow Coma Scale score, prothrombin time, and Sequential Organ Failure Assessment score. The mortality risk of phenotype 3 patients was the lowest at 28 days, 60 days, 90 days, and 1 year after ICU discharge ( Using machine learning methods, we successfully identified three clinical phenotypes of sepsis patients with different clinical characteristics and prognosis and screened out six key clinical features, which are expected to play an important role in the phenotype classification and prognostic assessment of sepsis and are conducive to individualized treatment.

Objective:
To analyze the disease burden of chronic obstructive pulmonary disease (COPD) and changes in its risk factors among residents in Zhejiang Province from 1990 to 2021, so as to identify key priorities for COPD prevention and control.
Methods:
Data on COPD mortality and disability-adjusted life years (DALY) for residents in Zhejiang Province from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. Standardized mortality and standardized DALY rate were calculated using the GBD 2021 world population standard structure. Premature mortality was computed via the life table method. The average annual percent change (AAPC) was applied to analyze trends in COPD mortality, DALY rate, and premature mortality. Changes in deaths of COPD risk factors were evaluated using population attributable fraction (PAF).
Results:
From 1990 to 2021, the standardized COPD mortality in Zhejiang Province decreased from 272.40/100 000 to 70.56/100 000 (AAPC=-4.395%), and the standardized DALY rate declined from 4 167.37/100 000 to 1 071.89/100 000 (AAPC=-4.396%). Similar downward trends were observed in both males (AAPC=-3.933%, -4.173%) and females (AAPC=-4.785%, -4.480%), all P<0.05. Crude mortality and DALY rates increased with age, and the crude mortality and DALY rates of various age groups in Zhejiang Province showed decreasing trends from 1990 to 2021 (all P<0.05). The premature mortality declined from 4.37% to 0.60% from 1990 to 2021 (AAPC=- 6.206%), with consistent trends across males and females (AAPC=- 6.144%, - 6.379%, all P<0.05). From 1990 to 2021, particulate matter pollution showed the largest reduction in PAF (- 56.76%), while ambient ozone pollution had the largest increase (103.07%) in Zhejiang Province. By 2021, smoking became the leading risk factor for deaths of COPD (PAF=43.32%).
Conclusions
The standardized mortality, standardized DALY rate, and premature mortality for COPD show consistent declining trends in Zhejiang Province from 1990 to 2021. However, risk factors such as smoking and ambient ozone pollution require intensified focus to further reduce disease burden of COPD.

Osteoarthritis (OA), the most prevalent joint disease of late life, is closely linked to cellular senescence. Previously, we found that the senescence of fibroblast-like synoviocytes (FLS) played an essential role in the degradation of cartilage. In this work, single-cell sequencing data further demonstrated that cartilage acidic protein 1 (CRTAC1) is a critical secreted factor of senescent FLS, which suppresses mitophagy and induces mitochondrial dysfunction by regulating SIRT3 expression. In vivo, deletion of SIRT3 in chondrocytes accelerated cartilage degradation and aggravated the progression of OA. Oppositely, intra-articular injection of adeno-associated virus expressing SIRT3 effectively alleviated OA progression in mice. Mechanistically, we demonstrated that elevated CRTAC1 could bind with NRF2 in chondrocytes, which subsequently suppresses the transcription of SIRT3 in vitro. In addition, SIRT3 reduction could promote the acetylation of FOXO3a and result in mitochondrial dysfunction, which finally contributes to the degradation of chondrocytes. To conclude, this work revealed the critical role and underlying mechanism of senescent FLSs-derived CRTAC1 in OA progression, which provided a potential strategy for the OA therapy.

Pelvic organ prolapse (POP), whose etiology is influenced by genetic and clinical risk factors, considerably impacts women's quality of life. However, the genetic underpinnings in non-European populations and comprehensive risk models integrating genetic and clinical factors remain underexplored. This study constructed the first polygenic risk score (PRS) for POP in the Chinese population by utilizing 20 disease-associated variants from the largest existing genome-wide association study. We analyzed a discovery cohort of 576 cases and 623 controls and a validation cohort of 264 cases and 200 controls. Results showed that the case group exhibited a significantly higher PRS than the control group. Moreover, the odds ratio of the top 10% risk group was 2.6 times higher than that of the bottom 10%. A high PRS was significantly correlated with POP occurrence in women older than 50 years old and in those with one or no childbirths. As far as we know, the integrated prediction model, which combined PRS and clinical risk factors, demonstrated better predictive accuracy than other existing PRS models. This combined risk assessment model serves as a robust tool for POP risk prediction and stratification, thereby offering insights into individualized preventive measures and treatment strategies in future clinical practice.

ObjectiveTo reveal the influence of Jianchangbang characteristic processing method on the change process of volatile components and the processing mechanism of reducing toxicity and increasing efficiency of Magnoliae Officinalis Cortex(MOC) by studying the changes in the composition and content of volatile components during the processing of ginger processed Xingpo pieces. MethodSamples of raw products, ginger juice moisturized products and stir-fried and heap moisturized products of MOC were taken according to the set time points, and headspace gas chromatography-mass spectrometry(HS-GC-MS) was used to determine the contents of volatile components in the samples, and the relative content of each component was obtained by peak area normalization. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were performed on the sample data using SIMCA 14.1 software, and the differential components during the processing were screened with variable importance in the projection(VIP) value>1 as the indicator. ResultA total of 68 volatile components were identified in the samples, among which some of the chemical components with similar structures showed similar trends of changes, and there was also the phenomenon of interconversion between compounds. Compared with the raw products, the contents of 42 components in ginger juice moisturized products increased, while the contents of 25 components decreased, 19 components were unique, and 4 components were unique to the raw products. Compared with ginger juice moisturized products, MOC in the early stage of piling had three unique components, and the contents of 11 components such as cyclosativene and (+)-α-pinene increased, and the contents of 5 components such as tricyclic terpene and α-curcumene decreased, and ginger juice moisturized products had four unique components. Compared with the early stage of piling, in the later stage, the contents of 8 components such as (+)-α-pinene and camphene significantly increased, while the contents of 6 components such as linalool and α-selinene significantly decreased. During the processing of MOC, there were significant changes in the chemical composition of the samples before and after 20 days. The differences between ginger juice moistening and the early stage of piling, the early stage and the later stage of piling could be clearly distinguished. ConclusionDuring the preparation process of ginger processed Xingpo pieces, the addition of ginger juice can reduce the contents of stimulating components, and the contents of active components continue to increase in several stages, such as the addition of ginger juice, frying and heap moisturizing, the quality of the decoction pieces may change significantly at about 20 d of processing. This study can provide a research basis for exploring the processing mechanism of ginger processed Xingpo pieces.

ObjectiveSodium hyaluronate (HA) was used as the research object to modify it with phenolic acid in order to obtain the molecular structure with better antioxidant activity or even new activity. MethodsIn this study, 5 kinds of phenolic acid-sodium hyaluronate was prepared by free radical-mediated grafting method, and the grafts with the highest grafting degree were selected to optimize the synthesis conditions. Then, grafts structure and physicochemical properties were analyzed. The grafts were characterized by IR, UV, 1H NMR, FESEM and TGA spectra. The in vitro antioxidant capacity of grafts was determined by the scavenging ability of DPPH·, ABTS+· and O2-·. ResultsAmong 5 kinds of phenolic acid-sodium hyaluronate, the grafting rate of ferulic acid-sodium hyaluronate copolymer (FA-HA) was highest , which was chosen as experimental sample in the following tests. Firstly, the reaction conditions were investigated and the highest grafting rate was (16.59±0.31) mg/g at the optimal preparation conditions. Then, FA-HA structure and physicochemical properties were analyzed. Data from UV, IR, 1H NMR analyses, TGA showed that FA were successfully grafted to HA. Compared with HA, the results of gel permeation chrematography (GPC) showed that the molecular mass distribution ofFA-HA copolymer decreased from 34.4 to 31.5 ku, but the uniformity of molecular distribution was improved. FESEM results showed that the structure of copolymer exhibited a closely connected lamellar structure with a relatively smooth surface. TGA results showed that thermal stability of FA-HA had a little decline. The antioxidant performance in vitro results showed that, during 0.25-10 g/L, FA-HA can eliminate (83.76±4.86)% DPPH·, (76.95±5.06)% ABTS+· and (83.08±2.51)% O2-· respectively at 10 g/L. which were higher than that of native HA and FA. ConclusionFA and HA were successfully grafted together by free radical grafting, and the grafted FA-HA had better antioxidant activity in vitro, which provided a theoretical basis for further research and development of phenolic acid-HA grafts.

Objective To investigate the spatiotemporal distribution characteristics and potential influencing factors of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, so as to provide insights into the formulation of the echinococcosis control strategy in Qinghai Province. Methods The number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases, number of registered dogs and number of stray dogs were captured from the annual reports of echinococcosis control program in Qinghai Province from 2016 to 2022, and the detection of newly diagnosed echinococcosis cases was calculated. The number of populations, precipitation, temperature, wind speed, sunshine hours, average altitude, number of year-end cattle stock, number of year-end sheep stock, gross domestic product (GDP) per capita, and number of village health centers in each county (district) of Qinghai Province were captured from the Qinghai Provincial Statistical Yearbook, and county-level electronic maps in Qinghai Province were downloaded from the National Platform for Common Geospatial Information Services. The software ArcGIS 10.8 was used to map the distribution of newly diagnosed echinococcosis cases in Qinghai Province, and the spatial autocorrelation analysis of newly diagnosed echinococcosis cases was performed. In addition, the spacetime scan analyses of number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases and geographical coordinates in Qinghai Province were performed with the software SaTScan 10.1.2, and the spatial stratified heterogeneity of the detection of newly diagnosed echinococcosis cases was investigated with the software GeoDetector. Results A total of 6 569 426 residents were screened for echinococcosis in Qinghai Province from 2016 to 2022, and 5 924 newly diagnosed echinococcosis cases were found. The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline over years from 2016 to 2022 (χ2 = 11.107, P < 0.01), with the highest detection in Guoluo Tibetan Autonomous Prefecture in 2017 (82.12/105). There were spatial clusters in the detection of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2018 (Moran’s I = 0.34 to 0.65, all Z values > 1.96, all P values < 0.05), and the distribution of newly diagnosed echinococcosis cases appeared random distribution from 2019 to 2022 (Moran’s I = −0.09 to 0.04, all Z values < 1.96, all P values > 0.05). Local spatial autocorrelation analysis showed high-high clusters and low-low clusters in the detection of new diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, and space-time scan analysis showed that the first most likely cluster areas of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022 were mainly distributed in Yushu Tibetan Autonomous Prefecture and Guoluo Tibetan Autonomous Prefecture. GeoDetector-based analysis of the driving factors for the spatial stratified heterogeneity of detection of newly diagnosed echinococcosis cases in Qinghai Province showed that average altitude, number of village health centers, number of cattle and sheep stock, GDP per capita, annual average sunshine hours, and annual average temperature had a strong explanatory power for the spatial distribution of newly diagnosed echinococcosis cases, with q values of 0.630, 0.610, 0.600, 0.590, 0.588, 0.537 and 0.526, respectively. Conclusions The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline in Qinghai Province over years from 2016 to 2022, showing spatial clustering. Targeted control measures are required in cluster areas of newly diagnosed echinococcosis cases for further control of the disease.
