OBJECTIVE To evaluate the efficacy and safety of total glucosides of paeonia （TGP） in the treatment of systemic lupus erythematosus （SLE）. METHODS Randomized controlled trial （RCT） about TGP combined with western medicine versus western medicine alone for SLE treatment were retrieved from PubMed， Embase， Cochrane Library， Web of Science， CNKI， VIP， Wanfang Data， and CBM. The search period spanned from the inception of each database to June 1， 2025. After literature screening， data extraction， and quality assessment of the included studies， Meta-analysis was performed using RevMan 5.4 software. RESULTS Fifteen RCTs， involving 1 318 patients， were included. Meta-analysis results showed that compared with western medicine alone， TGP combined with western medicine significantly improved clinical efficacy [OR＝4.96， 95%CI（3.41， 7.23）， P＜0.000 01]， complement 3 [MD＝0.18， 95%CI （0.13， 0.23）， P＜0.000 01] and complement 4[MD＝0.08， 般021） 95%CI （0.04， 0.11）， P＜0.000 01]， and reduced the levels of immunoglobulin G （IgG） [MD＝－3.10， 95%CI （－3.59，－2.62）， P＜0.000 01]， IgA [MD＝－0.68， 95%CI （－0.78， －0.58）， P＜0.000 01]， IgM [MD＝－0.43， 95%CI （－0.53，－0.34）， P＜0.000 01]， systemic lupus erythematosus disease activity index （SLEDAI） [MD＝－1.59， 95%CI （－2.20， －0.99）， P＜0.000 01]， recurrence rate [OR＝0.23， 95%CI （0.13， 0.42）， P＜0.000 01] and the incidence of adverse drug reactions [OR＝ 0.54， 95%CI （0.36， 0.82）， P＝0.004]. CONCLUSIONS TGP therapy can improve clinical efficacy of SLE patients， promote the restoration of immunoglobulins and complements， reduce SLEDAI and recurrence rate and has good safety.

Neurocritical care involves complex pathophysiological mechanisms, and its incidence is higher, injuries are more severe, and treatment is more challenging in high-altitude environments. This consensus, based on the latest domestic and international evidence-based medical data, establishes a standardized, goal-oriented framework for neurocritical care management applicable in high-altitude regions and nationwide. The consensus was developed following international standards for evidence quality assessment and underwent two rounds of Delphi expert consultation, resulting in 32 recommendation statements covering three parts: management systems, monitoring and assessment, and core strategies. Key updates include: advocating for the establishment of independent neurocritical care units and implementing precise tiered diagnosis and treatment based on the "Five Differences in Critical Care" concept; constructing a "trinity" multimodal brain monitoring system centered on cerebral blood flow, cerebral oxygenation, and brain function, emphasizing routine bedside transcranial Doppler ultrasound, cerebral oximetry, and continuous electroencephalography monitoring; shifting management strategies from mild hypothermia therapy to targeted temperature management, and defining the "446" target management pathway for the supercritical stage; emphasizing the assessment of static and dynamic cerebrovascular autoregulation functions through multimodal methods to achieve individualized optimal mean arterial pressure management; elevating cerebrospinal fluid management goals to the level of "glymphatic system" function maintenance; implementing a multidisciplinary collaborative, whole-process management model focusing on patients' long-term neurological functional outcomes; de-escalation criteria include multidimensional indicators such as recovery of brain structure, restoration of cerebrovascular autoregulation, improvement in cerebrospinal fluid dynamics, and reduction in biomarker levels; and integrating cutting-edge technologies like artificial intelligence into post-critical care management and rehabilitation planning. This consensus systematically integrates the entire process of neurocritical care management, reflecting the modern connotation of goal-oriented, dynamic, and multimodal integration in neurocritical care medicine. It aims to adapt to new trends such as deepening understanding of pathophysiological mechanisms, the integration of medicine and engineering, and the empowerment of artificial intelligence, thereby further advancing the discipline of critical care medicine.

ObjectiveTo investigate the mechanism by which Notoginsenoside R1 （NGR1） ameliorates hypoxia/reoxygenation （H/R）-induced injury in AC16 human cardiomyocyte cell lines through the regulation of mitophagy. MethodsCommon genes linked to hypoxia/reoxygenation injury and mitophagy were identified by intersecting data from GeneCards and MitoCarta databases. AC16 cell viability was assessed via CCK-8 assay under varying NGR1 concentrations （0， 6.25， 12.5， 25， 50， 100， 200， 300， 400， 500 μmol/L）. AC16 cells were divided into the following groups： control group （Control）， model group （H/R）， and treatment groups （H/R + NGR1 at 100， 200 and 300 μmol/L）. Mitochondrial membrane potential （ΔΨm） was measured using 5，5'，6，6'-tetrachloro-1，1'，3，3'-tetraethylbenzimidazolylcarbocyanine iodide （JC-1） staining. Transcriptional levels of mitophagy-related genes （Parkin， Pink1， P62） were quantified by reverse transcription-quantitative PCR （RT-qPCR）. Protein expression of mitophagy-related markers （Parkin， Pink1， P62， and LC3BⅡ） was evaluated via Western blot analysis. Mitochondrial ultrastructure was visualized by transmission electron microscopy （TEM）. ResultsCompared to the control group， cell viability in the H/R group significantly decreased （P<0.01）. Treatment with NGR1 at concentrations above 100 μmol/L significantly enhanced the cell viability of AC16 cells compared to the H/R group （P<0.01）. H/R induced a significant decrease in mitochondrial membrane potential （P<0.01）， which was restored by NGR1 treatment （P<0.01）. The mRNA levels of Parkin， Pink1， and P62 in the H/R group were upregulated compared to the control group （P<0.05）， while NGR1 intervention downregulated their expression （P<0.05）. Protein expression levels of Parkin， Pink1， and LC3BⅡ in the H/R group significantly increased， while P62 expression decreased compared to the control group （P<0.01）. In contrast， different doses of NGR1 treatment significantly reduced the expression of Parkin， Pink1， and LC3BⅡ while increasing P62 expression （P<0.05）. TEM revealed that the mitochondrial structure in the H/R group was severely disrupted， with fragmented and disorganized cristae， which was alleviated by NGR1. ConclusionNGR1 ameliorates H/R-induced AC16 cell injury， and its mechanism may be associated with modulating the Pink1/Parkin pathway to suppress excessive mitophagy.

: To analyze the prevalence of anemia and iron deficiency among primary and secondary school students in Rural Nutrition Improvement Program areas of Guizhou Province in 2023, and to explore the related factors, so as to provide evidence for Rural Nutrition Improvement Program optimization. Methods: In September 2023, a stratified random cluster sampling strategy was used to select 40 rural compulsory education schools with rural nutrition improvement program in five counties of Guizhou Province. School level questionnaire was employed to collect information of basic characteristics and school meal implementation. A total of 7 826 primary and secondary school students aged 6-16 underwent anthropometry and hemoglobin (Hb) determination; serum ferritin (SF) was additionally measured in a random subsample of 1 795 pupils. Students in Grade 3 and above also completed a questionnaire covering demographic characteristics, dietary behaviours and nutrition knowledge. Group comparisons were conducted by Chi square test or Fisher s exact test, and multivariable Logistic regression models were constructed to identify factors associated with anemia and iron deficiency. Results: The overall Hb level was (133.21±12.95)g/L, with an anemia prevalence of 7.17%. The overall SF level was (69.58±59.01)μg/L, with an iron deficiency prevalence of 2.73%. Multivariable analysis showed that stunting ( OR =1.88), school menus without nutrient calculation ( OR =1.61) and absence of menu planning software in the current semester ( OR =2.34) independently increased anemia risk, whereas obesity reduced it ( OR =0.54) (all P <0.05). Girls ( OR =4.16) and Grades 7-9 ( OR =5.93) increased iron deficiency risk (both P <0.05). Compared with rarely eating fresh vegetables, students with consuming <3 kinds per day ( OR =0.08) or exactly 3 kinds per day ( OR =0.06) had lower iron deficiency risks (both P <0.05). Conclusions Anemia and iron deficiency are prevalent among primary and secondary school students in Guizhou. Targeted intervention measures should be implemented for key populations to enhance the effectiveness of nutrition improvement program.

OBJECTIVE To establish the high-performance liquid chromatography （HPLC） fingerprint of Sagina japonica ， and to establish a quantitative analysis of multi-components by single-marker （QAMS） method for simultaneous determination of six componen ts in S. japonica ， aiming to provide references for the quality control of this medicinal herb. METHODS HPLC method was used to establish the fingerprints of 12 batches （No. S1-S12） of S . japonica according to Similarity Evaluation System of Chromatographic Fingerprint of Traditional Chinese Medicine . The similarity evaluation and identification of common peaks were conducted， followed by cluster analysis （CA） and principal component analysis （PCA） for 12 batches of samples. Using vicenin-2 as internal reference， the contents of p-hydroxy cinnamic acid， apigenin-6-C-arabinoside-8-C-glucoside， isoorientin， vitexin and 20-hydroxyecdysone were determined by QAMS method. The results were then compared with those obtained by the external standard method. RESULTS The similarities of HPLC fingerprints for 12 batches of S . japonica ranged from 0.828-0.998. A total of 17 common peaks were calibrated， and 6 common peaks were identified. Specifically， peak 5 was identified as vicenin-2， peak 7 as p-hydroxycinnamic acid， peak 10 as apigenin-6-C-arabinoside-8-C-glucoside， peak 11 as isoorientin， peak 13 as vitexin， and peak 15 as 20-hydroxyecdysone. The results of CA showed that S1-S5， S7 and S9-S11 were clustered into one category， S6 was clustered into one category， and S8 and S12 were clustered into one category. The results of PCA revealed that the accumulative contribution rate of the four main components was 89.430%. The content ranges measured by QAMS method for p-hydroxy cinnamic acid， apigenin-6-C-arabinoside-8-C-glucoside， isoorientin， vitexin and 20-hydroxyecdysone were 0.017 4-0.269 4， 0.568 8-4.240 3， 0.503 2-5.040 3， 0.024 0-0.132 0 and 2.551 3-4.881 1 mg/g， respectively. There was no significant difference in the contents of components measured between QAMS method and the external standard method （ P ＞0.05）. CONCLUSIONS The established HPLC fingerprint and QAMS method can be used for quality evaluation and quality control of S . japonica.

Chronic obstructive pulmonary disease（COPD）， characterized primarily by persistent airflow limitation and chronic airway inflammation， is a major chronic respiratory disease with persistently high morbidity and mortality. In recent years， macrophage pyroptosis， as an inflammatory form of programmed cell death， has been recognized as playing a key role in amplifying inflammatory responses and promoting tissue damage. According to traditional Chinese medicine（TCM） theory， spleen failing to disperse essence constitutes an important pathological basis for various chronic diseases， clinically manifesting as impaired transportation and transformation， internal generation of phlegm-dampness， and accumulation of turbid toxins. Based on a review of classical TCM pathogenesis and modern molecular biological research， this study proposes that there may be a correlation between spleen failing to disperse essence and macrophage pyroptosis in the pathogenesis of COPD. Specifically， metabolic and immune disturbances such as glucotoxicity， lipotoxicity， and enterotoxicity may trigger macrophage pyroptosis through the advanced glycation end products（AGEs）/AGEs receptor（RAGE）/reactive oxygen species（ROS）， fatty acids/Toll-like receptor 4（TLR4）， and lipopolysaccharide（LPS）/nuclear transcription factor-κB（NF-κB）/NOD-like receptor protein 3（NLRP3） signaling pathways. Excessive pyroptosis， in turn， exacerbates metabolic dysregulation and inflammatory responses， forming a vicious cycle. Furthermore， TCM interventions such as strengthening the spleen and tonifying Qi， as well as resolving dampness and detoxifying， have demonstrated potential in modulating pyroptosis-related signaling pathways， including NF-κB， the NLRP3 inflammasome， and autophagy. In summary， this article explores the role of spleen failing to disperse essence-macrophage pyroptosis mechanism in COPD and highlights possible therapeutic strategies of TCM， providing new insights for integrated Chinese and western medical research and clinical practice.

ObjectiveTo investigate the effect of laminin subunit α3 （LAMA3） on the epithelial-mesenchymal transition （EMT）， invasion， and metastasis abilities of pancreatic cancer （PC）. MethodsA comprehensive analysis was performed for tumor- and EMT-related databases to identify the EMT genes associated with PC， especially LAMA3. The methods of qRT-PCR and Western blot were used to measure the expression level of LAMA3 in PC tissue and cell lines； immunofluorescence assay was used to determine the localization of LAMA3 in PANC-1 cells； Transwell assay was used to investigate the effect of LAMA3 on the invasion and migration abilities of PC cells. The t-test was used for comparison of continuous data between groups. ResultsThe analysis of the TCGA database identified 3 EMT-related oncogenes for PC， i.e.， LAMA3， AREG， and SDC1. The LASSO-Cox regression model showed that LAMA3 had the most significant impact on the prognosis of PC （risk score=0.256 1×LAMA3+0.043 1×SDC1+0.071 4×AREG）. The Cox model and nomogram showed that the high expression of LAMA3 was an independent risk factor for the poor prognosis of PC （hazard ratio=1.32， 95% confidence interval： 1.07‍ ‍—‍ 1.62， P<0.01）. Experimental results showed that there was a significant increase in the expression of LAMA3 in pancreatic cancer tissue compared with the normal pancreatic tissue. Compared with the HPDE cell line， there were varying degrees of increase in the expression of LAMA3 in pancreatic cancer AsPC-1， BxPC-3， PANC-1， MIA PaCa-2， and SW1990 cell lines， with the highest expression level in PANC-1 cells. The enrichment analysis showed that LAMA3 was associated with the biological processes and signaling pathways such as EMT， collagen metabolism， extracellular matrix degradation， the TGF-β pathway， and the PI3K pathway. After the knockdown of LAMA3， there were significant reductions in the expression levels of N-Cadherin， Vimentin， and Snail， while there was a significant increase in the expression level of E-Cadherin. Transwell assay showed that there were significant reductions in the invasion and migration abilities of PANC-1 cells after the knockdown of LAMA3. ConclusionLAMA3 is highly expressed in PC and can promote the EMT， invasion， and migration of PC cells， and therefore， LAMA3 may be used as a novel diagnostic marker and a new therapeutic target for PC.

ObjectiveTo explore the therapeutic effects and mechanisms of modified Danggui Shaoyaosan on acne based on the c-Jun N-terminal kinase （JNK）/p38 mitogen-activated protein kinase （p38 MAPK） pathway. MethodsA rat ear acne model was established in SD rats， and the rats were divided into a blank group， a model group， and low-， medium-， and high-dose groups of modified Danggui Shaoyaosan （7.15， 14.30， 28.60 g·kg·d^-1）， with six rats in each group. After the administration for 14 consecutive days， morphological changes in the rats' auricles were observed， and hematoxylin-eosin （HE） staining was used to examine the pathological changes in the acne-affected ear tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in the ear tissue. Quantitative reverse transcription polymerase chain reaction （Real-time PCR） was performed to detect the mRNA expression levels of Caspase-3， B cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， JNK， and p38 MAPK in the ear tissue. Additionally， Western blot analysis was conducted to assess the protein levels of Caspase-3， Bcl-2， Bax， JNK， and p38 MAPK in the ear tissue. The active components and key targets of modified Danggui Shaoyaosan in the treatment of acne were identified through network pharmacology analysis. Molecular docking was then employed to evaluate the interactions between the main active components and the key targets. ResultsThe results of the animal experiment demonstrated that compared with those in the blank group， rats in the model group exhibited redness， swelling， thickening， hardening， dryness， and roughness of the auricle. The surface showed sebaceous scales and desquamation， accompanied by acne-like lesions such as papule-like elevations or cysts. Histopathological changes included keratinization， epidermal thickening， dermal collagen fiber degeneration and necrosis， subcutaneous muscle degeneration and necrosis， inflammatory cell infiltration， and fibrous tissue proliferation. The mRNA and protein expression levels of IL-1β， TNF-α， Caspase-3， Bax， JNK， and p38 MAPK were significantly increased （P<0.01）， while those of Bcl-2 were significantly decreased （P<0.01）. In comparison to the model group， the modified Danggui Shaoyaosan groups showed marked improvement in acne-like lesions of the auricle， with varying degrees of histopathological damage reduction. Additionally， the mRNA and protein expression levels of IL-1β， TNF-α， Caspase-3， Bax， JNK， and p38 MAPK in the tissue were significantly decreased （P<0.05， P<0.01）， while those of Bcl-2 were significantly increased （P<0.05， P<0.01）. Network pharmacology analysis indicated that the key compounds in modified Danggui Shaoyaosan responsible for its effects in treating acne may include acacetin， kaempferol， luteolin， quercetin， wogonin， and baicalein. These compounds exerted their effects by modulating core targets such as TNF， IL-1β， Caspase-3， and Bcl-2， thereby alleviating inflammation and apoptosis and ultimately improving acne symptoms. ConclusionModified Danggui Shaoyaosan may exert its therapeutic effects on acne by inhibiting the activation of the JNK/p38 MAPK pathway， thereby alleviating inflammation and apoptosis.

Erectile dysfunction （ED） is one of the most common manifestations of male reproductive system damage， and it is also a common complication of diabetes mellitus （DM）. ED is closely related to the patient’s quality of life， sexual partner relationship， and family stability. In addition， it is an early warning signal for many physical diseases. As the incidence of DM keeps growing， the incidence of diabetes mellitus-induced erectile dysfunction （DMED） increases accordingly. Currently， drug treatment for ED presents limited effects， and the treatment of DMED is more difficult. Therefore， developing effective and safe drugs is a clinical problem that needs to be solved urgently. Recent studies have proved that traditional Chinese medicine （TCM） can alleviate oxidative stress， reduce inflammation， and modulate autophagy by regulating multiple signaling pathways， thus ameliorating DMED， showing definite therapeutic effects via multiple pathways， targets， and links. Multiple signaling pathways such as phosphatidylinositol-3-kinase/protein kinase B （PI3K/Akt）， nitric oxide （NO）-cyclic guanosine monophosphate （cGMP）， Ras homolog family member A （RhoA）/Rho， nuclear factor erythroid 2-related factor 2 （NRF2）， mitogen-activated protein kinase （MAPK）， adenosine monophosphate-activated protein kinase （AMPK）， and protein kinase C （PKC） mediate the occurrence and development of DMED， while there is still a lack of conclusive records. By reviewing relevant articles published in recent years， this paper summarizes the role of the above-mentioned signaling pathways in the occurrence and development of DMED and the research progress in TCM treatment of DMED via regulation of related signaling pathways. This review is expected to provide new ideas and references for further clinical diagnosis and treatment， basic research， and drug development.
