Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Achondroplasia (ACH) is a common inherited skeletal dysplasia (inherited dwarfism) that compromises quality of life across the lifespan. In 2021, vosoritide became the first approved precision therapy for ACH and is now available in more than 40 countries. Compared with prior symptomatic measures, vosoritide has demonstrated favorable efficacy and a reassuring safety profile. Nevertheless, existing international ACH guidelines largely emphasize complication management and symptomatic care, and there is no unified consensus on pharmacologic therapy. To address this gap, an international expert group developed the International Consensus Guidelines for the Implementation and Monitoring of Vosoritide Therapy in Patients with Achondroplasia providing systematic recommendations that span the continuum of care - from initial patient contact and pre-treatment assessment to medication counseling, injection training, and long-term outcome monitoring. These recommendations complement and refine current management and nursing protocols for individuals with ACH and offer practical guidance for clinicians across diverse regions. This article highlights key elements of the guideline to provide evidence-based support and clinical direction for healthcare professionals in China treating children with ACH using vosoritide.

OBJECTIVE To establish the UPLC fingerprint and the method for multi-component content determination in Jingangteng capsules， and to evaluate its quality by combining chemical pattern recognition analysis. METHODS An UPLC method was established. Separation was performed on a Zorbax SB-C 18 Rapid Resolution HD column， with acetonitrile-0.1% formic acid as the mobile phase for gradient elution.Using the Similarity Evaluation System for Chromatographic Fingerprints of Traditional Chinese Medicines （2012 edition）， UPLC fi ngerprints were established for 10 batches of Jingangteng capsules， and similarity was evaluated. SPSS 22.0 and SIMCA 14.1 software were used to perform hierarchial-cluster analysis and orthogonal partial least squares discriminant analysis （OPLS-DA）， respectively. The same UPLC method was employed to determine the contents of chlorogenic acid， 3，5-dihydroxy-2-methylbenzoic acid-3- O -glucoside （M1）， caffeic acid， astilbin， oxyresveratrol， quercitrin and resveratrol in the 10 batches of samples. RESULTS A total of 17 common peaks were identified in UPLC fingerprints of the 10 batches of samples， of which 7 were identified as chlorogenic acid， M1， caffeic acid， astilbin， oxyresveratrol， quercitrin， and resveratrol. The similarities of 10 batches of samples ranged from 0.820 to 0.985. The results of hierarchial-cluster analysis showed that 10 batches of samples were grouped into four categories： S1-S4 formed one group， S5 and S6 formed another， S7， S8 and S10 formed a third， and S9 formed a fourth， consistent with the OPLS-DA results； the variable importance projection values for peaks 7， 10， 2， 16 （resveratrol）， 13 （oxyresveratrol）， 11， 6 （caffeic acid）， 5 （M1） and 15 （quercitrin） were ＞1. Quantitative analysis results showed that the contents of chlorogenic acid， M1， caffeic acid， astilbin， oxyresveratrol， quercitrin， and resveratrol were 1.650 8-4.213 7， 0.636 2-2.161 7， 0.031 0-0.086 5， 0.239 1-1.069 3， 0.211 9-1.104 0， 0.488 8-2.399 2， and 0.164 0-0.699 8 mg/g， respectively. CONCLUSIONS UPLC fingerprint and content determination methods established in this study are simple to operate， accurate， reliable and reproducible； when combined with chemical pattern recognition analysis， they can be used to evaluate the quality of Jingangteng capsules. Nine components， such as resveratrol， oxyresveratrol， caffeic acid， M1 and quercitrin， may serve as markers of quality variation.

Objective To investigate the protective effect of mitochondrial fission inhibitor 1(Mdivi-1),on organ function in rats with explosive blast injury combined with hemorrhagic shock.Methods A total of 192 SD rats(half male and half female,12 weeks old,weighing about 220 g)were randomly divided into 6 groups:Sham group(only surgical incision along the midline of the abdomen),model group(ESH group,thermal radiation and shock wave injury followed by femoral artery hemorrhage),lactated Ringer's solution resuscitation group(ESH+LR group,LR solution infusion in the femoral vein for resuscitation),and low-,middle-and high-dose Mdivi-1 groups(0.1,0.5 and 1.0 mg/kg Mdivi-1 intervention after infusion of LR solution).Fluorescent protein tracing was used to determine the leakage amount of fluorescent protein in the lung and kidney tissues to evaluate the vascular permeability.Evans blue dye staining was employed to observe the intestinal permeability and pulmonary vascular permeability.Laser Doppler flowmetry was applied to monitor the tissue blood perfusion in the liver,kidneys,and intestine.Serum levels of cardiac injury marker troponin I(TNI),liver function markers aspartate aminotransferase(AST)and alanine aminotransferase(ALT),and renal function markers serum creatinine(Scr)and blood urea nitrogen(BUN)were detected to evaluate the functions of corresponding organs.The water contents of the lungs and brain were calculated by measuring wet weight and dry weight of the lung and brain tissues.Blood pressure,heart rate,and respiratory rate were monitored.The survival time and 72-hour survival rate were recorded and calculated.Results Compared with the Sham group,the ESH group exhibited significantly increased vascular permeability in the lungs and kidneys as well as intestinal tissue(P<0.05),along with obviously elevated water contents in the lungs and brain(P<0.05),and decreased blood perfusion in the liver,kidneys,and intestine by 57.1%,39.2%,and 43.2%of the Sham group,respectively(P<0.05),elevated levels of TNI,AST,ALT,Scr and BUN(P<0.05),mean survival time of 3.8±1.1 h,and a 72-hour survival rate of 0(P<0.05).Although LR solution resuscitation reduced vascular permeability and alleviated organ injury in rats with explosive injury combined with hemorrhagic shock,there were no significant differences compared to the ESH group(P>0.05).Mdivi-1 treatment notably decreased vascular permeability in the lungs and kidneys and intestine,and water contents in the lungs and brain when compared with the LR group(P<0.05),with the dose of 0.5 mg/kg demonstrating the most significant effect.Additionally,Mdivi-1 treatment also significantly enhanced organ perfusion,improved organ functions,prolonged survival time,and increased survival rate.The 0.5 mg/kg treatment resulted in a 72-hour average survival time 55.64 h and a survival rate of 62.5%.Conclusion Mitochondrial fission inhibitor Mdivi-1 can reduce the permeabilities in the lungs,kidneys and intestine,improve tissue blood perfusion,protect the organ functions of the heart,liver and kidneys,and finally prolong survival time and increase survival rate in rats with concomitant explosive blast injury and hemorrhagic shock.

Cytokeratin 19 fragment antigen 21-1(CYFRA21-1)is a new biomarker which has received much attention in recent years for cancer screening,and has shown great potentials for screening and diagnosis of various cancers,especially non-small cell lung cancer.CYFRA21-1 level in human serum has important clinical significance in the diagnosis,prognosis and treatment of lung cancer.Recently,a variety of detection techniques have been established to effectively enrich the detection technology system of CYFRA21-1,such as enzyme-linked immunosorbent assay,chemiluminescence,fluorescence,immunochromatography,electrochemical method,and surface enhanced Raman spectroscopy,etc.These techniques provide technical support for early diagnosis of lung cancer.However,the research progress of CYFRA21-1 detection methods is rarely reported.In this paper,CYFRA21-1 and its clinical significance were briefly introduced,and the progress of detection technology in recent ten years was reviewed,which was expected to provide reference for developing more sensitive,accurate,fast and convenient detection methods.

In this study,a sensitive lateral flow immunoassay(LFIA)platform based on carbon dots-mesoporous silica nanocomposite(CD-MSNs)fluorescent probes was constructed for high-performance detection of inflammatory marker interleukin-6(IL-6).Green fluorescent carbon dots(CDs)were prepared by hydrothermal method with 3,9-perylenic acid and 3-aminopropyltriethoxysilane(APTES)as raw materials,and highly fluorescent CD-MSNs composites were then constructed by encapsulating the prepared CDs in mesoporous silica nanoparticles(MSNs).Fluorescent probes were prepared by covalent coupling of CD-MSNs with IL-6 antibody.Fluorescent immunochromatographic test strips were constructed by spraying IL-6 capture antibody and goat anti-mouse IgG on nitrocellulose membrane as detection line(T-line)and quality control line(C-line),respectively.The fluorescence immunoassay analyzer was used to quantitatively detect the fluorescence intensity of T-line,and the experimental results showed that the LFIA platform based on this probe had a good linear relationship in IL-6 concentration range of 102-106 pg/mL,and the detection limit was 64 pg/mL,which was two orders of magnitude more sensitive than that of the traditional colloidal gold test strips.This method effectively solved the issue of insufficient sensitivity of traditional LFIA technique,and provided a rapid and highly sensitive detection method for early diagnosis of inflammatory diseases.

Objective:To explore the diagnostic value of the macrophage activation syndrome/systemic juvenile idiopathic arthritis（MS）score in macrophage activation syndrome（MAS）associated with systemic juvenile idiopathic arthritis（sJIA），and to provide a reference for clinical work.Methods:This study was a retrospective case-control analysis，conducted on the patients initially diagnosed as sJIA-associated with MAS and admitted into the Department of Rheumatology and Immunology of Children's Hospital Affiliated to Xi 'an Jiaotong University from July 1st，2016 to June 30th，2023. All of the patients met the diagnostic criteria for patients with MAS associated with sJIA according to the 2016 European Alliance of Associations for Rheumatology（EULAR）/American College of Rheumatology（ACR）/Pediatric Rheumatology International Trials Organization（PRINTO）standards. The basic information at baseline，clinical manifestations，and auxiliary examination results were collected. The MS score was applied to re-evaluate the children diagnosed as sJIA-associated with MAS. When the MS score ≥-2.1，the possibility of sJIA with MAS was high. Thirty cases of sJIA without MAS were randomly selected as the control group.Results:There were 28 cases in the MAS group，including 13 males（46.43%）and 15 females（53.57%），with an average age of（7.51±4.01）years. Compared with the control group，the MAS group were significantly more likely to have high fever（ χ2=8.539， P=0.003），hepatomegaly（ χ2=11.621， P<0.001），splenomegaly（ χ2=11.710， P<0.001）and neurological involvement（ χ2=27.619， P<0.001），with the differences being statistically significant. Meanwhile，there were statistically significant differences between the two groups in terms of white blood cell count（ Z=-4.001， P<0.001），neutrophil count（ Z=-3.659， P<0.001），platelet count（ Z=-4.687， P<0.001），albumin level（ Z=-4.018， P<0.001），alanine aminotransferase（ Z=-3.846， P<0.001），aspartate aminotransferase（ Z=-5.932， P<0.001），lactate dehydrogenase（ Z=-6.150， P<0.001），triglycerides（ Z=-5.874， P<0.001），fibrinogen（ Z=-5.808， P<0.001），ferritin（ Z=-5.280， P<0.001），erythrocyte sedimentation rate（ Z=-3.971， P<0.001），ferritin/erythrocyte sedimentation rate（ Z=-5.433， P<0.001），reduction of two-line cells in blood（ χ2=11.408， P<0.001）and the presence of hemophagocytosis in bone marrow smears（ χ2=28.260， P<0.001）. Moreover，there was a statistically significant difference in MS scores between the two groups（ Z=-6.148， P<0.001），with higher MS scores in the MAS group. Nevertheless，this study showed the median MS scores of both groups ≥-2.1. Conclusion:The MS score was significant to a certain degree as reference for the diagnosis of MAS，and this study showed that the MS score in the MAS group was significantly higher than the control group. However，the median MS scores in both groups were no less than -2.1. This might be related to the influence of factors during the assessment，which made it necessary to optimize the cutoff values of the MS score. Therefore，prospective studies should be carried out on the role of MS score in early identification of MAS.

Objective To investigate the changes and clinical significance of serum caveolin-1(Cav-1)and myeloid cell leukemia-1(Mcl-1)levels in patients with sepsis-induced acute lung injury(S-ALI).Methods A total of 198 patients with S-ALI admitted to the hospital from January 2021 to September 2024 were selected as the S-ALI group.They were divided into mild S-ALI group(52 cases),moderate S-ALI group(72 cases),and severe S-ALI group(74 cases)based on disease severity(oxygenation index).According to the 28 day prognosis after admission,they were divided into death group(65 cases)and survival group(133 cases).Addi-tionally,70 healthy individuals during the same period were selected as the control group.Serum Cav-1 and Mcl-1 levels were measured using enzyme-linked immunosorbent assay.The correlation between serum Cav-1 and Mcl-1 levels and the oxygenation index in S-ALI patients was analyzed using Spearman's correlation.Mul-tivariate Logistic regression and receiver operating characteristic(ROC)curve analysis were performed to e-valuate the relationship between serum Cav-1 and Mcl-1 levels and the prognosis of S-ALI patients,as well as their predictive value.Results Serum Cav-1 level in the S-ALI group was lower than that in the control group(P＜0.05),while Mcl-1 level was higher than that in the control group(P＜0.05).In S-ALI patients,the oxy-genation index was negatively correlated with serum Cav-1 level(P＜0.05)and positively correlated with Mcl-1 level(P＜0.05).Serum Cav-1 level progressively decreased(P＜0.05),and Mcl-1 level progressively increased across the mild,moderate,and severe S-ALI groups(P＜0.05).The 28 day mortality rate among the 198 S-ALI patients was 32.83％(65/198).Cav-1 was identified as an independent protective factor(P＜0.05),while Mcl-1 was an independent risk factor for mortality in S-ALI patients(P＜0.05).The area under the curve of the combined prediction of serum Cav-1 and Mcl-1 levels for the mortality in S-ALI patients was 0.881,which was larger than 0.798 and 0.779 of Cav-1 and Mcl-1 alone(P＜0.05).Conclusion Decreased serum Cav-1 level and increased Mcl-1 level are closely associated with increased disease severity and mortality in S-ALI patients.The combined detection of serum Cav-1 and Mcl-1 levels has high prognostic value for S-ALI patients.

Objective: To evaluate the feasibility of dynamic contrast-enhanced MRI (DCE-MRI) in differentiating tumor deposits (TDs) from metastatic lymph nodes (MLNs) in rectal cancer. Materials and Methods: A retrospective analysis was conducted on 70 patients with rectal cancer, including 168 lesions (70 TDs and 98 MLNs confirmed by histopathology), who underwent pretreatment MRI and subsequent surgery between March 2019 and December 2022. The morphological characteristics of TDs and MLNs, along with quantitative parameters derived from DCE-MRI (K trans , kep, and v e) and DWI (ADCmin, ADCmax, and ADCmean), were analyzed and compared between the two groups.Multivariable binary logistic regression and receiver operating characteristic (ROC) curve analyses were performed to assess the diagnostic performance of significant individual quantitative parameters and combined parameters in distinguishing TDs from MLNs. Results: All morphological features, including size, shape, border, and signal intensity, as well as all DCE-MRI parameters showed significant differences between TDs and MLNs (all P < 0.05). However, ADC values did not demonstrate significant differences (all P > 0.05). Among the single quantitative parameters, v e had the highest diagnostic accuracy, with an area under the ROC curve (AUC) of 0.772 for distinguishing TDs from MLNs. A multivariable logistic regression model incorporating short axis, border, v e, and ADC mean improved diagnostic performance, achieving an AUC of 0.833 (P = 0.027). Conclusion The combination of morphological features, DCE-MRI parameters, and ADC values can effectively aid in the preoperative differentiation of TDs from MLNs in rectal cancer.
