Qingzao Jiufeitang is a famous classical formula for treating lung injury caused by warm and dryness， included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. By systematically organizing ancient and modern literature on this formula， this study analyzed and verified the origin， medicinal composition， original plants and processing， dosage and decoction method， efficacy and application of this formula. According to the research， Qingzao Jiufeitang was first recorded in Yimen Falyu in the Qing dynasty， and its creation was mainly inspired by the Ming dynasty physician MIAO Xiyong's idea of the moisturizing drugs with sweet flavour and cold nature. Based on the 2020 edition of the Pharmacopoeia of the People's Republic of China（hereinafter referred to as the Chinese Pharmacopoeia） and the textual research results of modern scholars on traditional Chinese herbal medicines， the botanical sources and processing methods of the herbs in this formula are basically clarified. Among them， Mori Folium， Gypsum Fibrosum， Ginseng Radix et Rhizoma， Sesami Semen Nigrum， Asini Corii Colla， Ophiopogonis Radix and Eriobotryae Folium are consistent with the 2020 edition of the Chinese Pharmacopoeia. The primary source of Glycyrrhizae Radix et Rhizoma is the dried roots and rhizomes of Glycyrrhiza uralensis， family Leguminosae， while the primary source of Armeniacae Semen Amarum is the dried mature seeds of Prunus armeniaca， family Rosaceae. It is recommended to use Gypsum Ustum， stir-fried Sesami Semen Nigrum， stir-fried Armeniacae Semen Amarum， Asini Corii Colla bead， and honey-fried Eriobotryae Folium， and the rest of the raw products. According to the conversion of ancient and modern doses， the recommended dosages are 11.19 g for Mori Folium， 9.33 g for Gypsum Fibrosum， 3.73 g for Glycyrrhizae Radix et Rhizoma， 2.61 g for Ginseng Radix et Rhizoma， 3.73 g for Sesami Semen Nigrum， 4.48 g for Ophiopogonis Radix， 2.61 g for Armeniacae Semen Amarum， 3.73 g for Eriobotryae Folium. The decoction method is to add 300 mL of water， decoct it down to 180 mL， remove the residue， and then add 2.98 g of Asini Corii Colla into the decoction. Take it warm after meals， two to three times a day. Qingzao Jiufeitang has the effects of clearing dryness and moistening the lungs， nourishing Yin and invigorating Qi. In ancient times， it was mainly used to treat stagnation and depression of various Qi， as well as paralysis， asthma and vomiting. In modern clinical practice， it is mostly used to treat diseases in respiratory system， otolaryngology， skin system and digestive system caused by warm-dry impairing lung， deficiency of both Qi and Yin. The above research results can provide a reference for the later development of Qingzao Jiufeitang.

Cancer ranks as the second leading cause of death globally and has surpassed cardiovascular diseases to become the primary cause of mortality in developed countries. Cancer stem cells (CSCs), which play crucial roles in cancer recurrence, metastasis, and drug resistance, have attracted significant attention in targeted therapeutic strategies. Aptamers, with unique three-dimensional structures capable of specifically recognizing the surface markers of CSCs, show promising potential in targeted drug delivery systems. Compared with conventional antibodies, aptamers are praised for small molecular weights, low production costs, and easy chemical modification. This review systematically summarizes recent advances in aptamer research targeting the surface markers of CSCs, with particular emphasis on aptamer-drug conjugate systems targeting the markers including EpCAM, CD133, CD44, and ABCG2. Both in vitro cellular studies and in vivo animal models have demonstrated the definite anti-cancer efficacy of aptamer-based drug delivery systems, which are of great significance to develop novel therapeutic strategies and improving the therapeutic effects of CSC-targeted treatment. Thus, aptamer-based drug delivery system has broad application prospects in the field of precise cancer treatment.

ObjectiveTo investigate the effect of modified Baduanjin exercise, as an rehabilitation exercise, on cardiopulmonary function, motor function and activities of daily living in patients with stroke. MethodsFrom January to September, 2023, 42 stroke patients in the Nanjing Qixia District Hospital were randomly divided into control group (n = 21) and experimental group (n = 21). The control group received routine rehabilitation, and the experimental group received modified Baduanjin exercise in addition, for four weeks. They were assessed with peak oxygen uptake (VO_2peak), anaerobic threshold (AT), peak oxygen pulse (VO_2peak/HR), forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁), peak expiratory flow (PEF), Fugl-Meyer Assessment-upper extremities (FMA-UE), Berg Balance Scale (BBS) and modified Barthel Index (MBI) before and after intervention. ResultsVO_2peak, AT, and the scores of FMA-UE, BBS and MBI improved in the control group after intervention (|t| > 2.256, |Z| > 2.936, P < 0.05); while VO_2peak, AT, VO_2peak/HR, FVC, FEV₁, PEF, and the scores of FMA-UE, BBS and MBI improved in the experimental group (|t| > 4.390, |Z| > 3.451, P < 0.001); and all the indexes were better in the experimental group than in the control group (|t| > 4.136，|Z| > 2.751，P < 0.01), except the scores of BBS and MBI. ConclusionModified Baduanjin exercise can improve the cardiopulmonary function and upper limb motor function for stroke patients.

Objective To rapidly visualize and detect the extracellular vesicles of glial cells in a simulated space environment.Methods By using 2,5 Gy irradiation and 12,24 h microgravity treatment,a damage model of glial cells was established in a simulated space environment.Exosomes extracted from conditioned media with reagent kits were transferred to neurons to elucidate the impact of glial cells on neurons.By performing live-cell fluorescence labeling of exosomes,a visualization monitoring scheme based on fluorescence intensity analysis was developed to characterize the release patterns of extracellular vesicles.The release patterns of exosomes were represented by the fluorescence intensity of the conditioned media.The effects of different storage conditions and duration on the quantity and size of exosomes were investigated.Results The exosomes released from damaged glial cells in the simulated space environment could to some extent protect neurons,with exosomes playing a decisive role in this process,and the neurosystem exosome visualization detection scheme was consistent with the traditional exosome validation scheme.An empirical curve for exosome quantity and size was established for semi-quantitative analysis,providing a new approach for rapid detection of exosomes in cell culture media.Furthermore,the optimal storage conditions for culture medium samples were clarified,laying the foundation for ground/space-based online analysis of culture medium samples after spaceflight.Conclusion Exosome rapid detection and analysis can be achieved through fluorescence labeling and utilized to investigate glial cell injury in a simulated space environment.

Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.

As an emerging discipline that combines traditional diagnostic methods with modern scientific technology,micro syndrome differentiation has good prospects for development,but there are some controversies in the research process.Based on ancient and modern literature,this article reviewed the origin and flow of research on micro syndrome differentiation,and summarized the problems to be improved in the process of research on micro syndrome differentiation from three aspects:application of disease type,guiding ideology and micro indicators.Based on this,the article further expounded the new thinking on"near-micro"syndrome differentiation from three aspects:connotation,scope of application,and links to traditional identification and micro-identification,and pointed out that the modern medical detection basis should be incorporated into the field of TCM syndrome differentiation,and at the same time,it should be based on the overall thinking mode of TCM,which would provide a new idea for the development of modern TCM diagnosis technology.

ObjectiveTo investigate the inhibitory effect of Mahuang Xixin Fuzitang on the migration of dendritic cells （DCs） in mice and its underlying mechanism. MethodMouse bone marrow-derived DCs were isolated and cultured. The morphological changes of the cells at different stages were observed under a microscope， and the CD11c⁺ proportion was detected by flow cytometry to identify DC purity. Cells were treated with Mahuang Xixin Fuzitang （1， 2， 5， 10， 20， 40， 50， 100 g·L^-1） for 24 hours， and the effect of Mahuang Xixin Fuzitang on cell proliferation was assessed using the cell counting kit-8 （CCK-8） assay to determine the appropriate concentrations for treatment. After modeling by lipopolysaccharide （LPS） induction， DCs were divided into a blank group， a model group， and Mahuang Xixin Fuzitang groups （2， 4， 8 g·L^-1）. The expression of surface molecules CD80， CD86， and major histocompatibility complex-Ⅱ （MHC-Ⅱ） were detected by flow cytometry. Transwell chamber assay was used to observe cell migration. The levels of chemokine C-C-primitive receptor 7 （CCR7） and chemokine C-X-C-primitive receptor 4 （CXCR4） on the cell surface were detected by enzyme-linked immunosorbent assay （ELISA）. The expression of filamentous actin （F-actin） in the cell microfilament cytoskeleton was detected by immunofluorescence （IF） staining. Real-time quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA expression levels of Ras homolog family member A （RhoA） and Rho-associated coiled-coil containing protein kinase 1 （ROCK1）. Western blot analysis was performed to detect the protein expression of RhoA and ROCK1. ResultCompared with the blank group， the model group exhibited significantly higher expression levels of CD80， CD86， and MHC-Ⅱ （P<0.01）， a significantly increased number of cells migrating to the lower chamber （P<0.01）， and significantly elevated levels of CCR7 and CXCR4 （P<0.05， P<0.01）. Additionally， F-actin expression was significantly increased （P<0.01）， and both RhoA and ROCK1 mRNA and protein expression levels were significantly higher （P<0.05， P<0.01）. Compared with the model group， treatment with Mahuang Xixin Fuzitang （2， 4， 8 g·L^-1） for 24 hours resulted in significantly lower expression levels of CD80， CD86， and MHC-Ⅱ （P<0.01）， a significantly reduced number of cells migrating to the lower chamber （P<0.05）， and significantly decreased levels of CCR7 and CXCR4 （P<0.05， P<0.01）. Furthermore， F-actin expression was significantly reduced （P<0.01）， and both RhoA and ROCK1 mRNA and protein expression levels were significantly decreased （P<0.05， P<0.01）. ConclusionMahuang Xixin Fuzitang can inhibit the migration of DCs in mice， and its mechanism of action may be related to reducing the activity of the Rho/ROCK signaling pathway， thereby affecting changes in the cell cytoskeleton.

[Objective]To identify the relationship between tumor tissue interleukins(ILs)and non-small cell lung cancer(NSCLC)patients with poor response to immune checkpoint blockade(ICB)therapy,and to investigate the differ-ential expression of ILs in tumor of NSCLC patients as well as its effect on ICB response and prognosis.[Methods]A total of 61 patients diagnosed with NSCLC and treated with ICB were retrospectively collected from the data of a previous study.We obtained transcriptome sequencing data from tumor tissues and survival data of the patients before ICB treatment.Us-ing bioinformatics methods,we screened for ILs that significantly affected the efficacy and prognosis of ICB treatment.We evaluated the efficacy of ICB treatment using progressive-free survival(PFS)and assessed the prognosis using overall sur-vival(OS).The Kaplan-Meier survival curve and ROC curve were used to analyze the predictive effect and efficacy of ILs on the efficacy and prognosis of ICB in NSCLC patients.[Results]The results of the univariate Cox regression analysis in our study showed that nine ILs were found to be associated with OS of NSCLC patients treated with ICB at a significance level of P<0.1.Further multivariate analysis revealed that high expression of IL-11,IL-17D,and IL-36A was significant-ly associated with poor prognosis in these patients(P<0.05).The results from the Kaplan-Meier survival curve analysis revealed a significant negative correlation between the high expression of IL-17D and both PFS and OS in NSCLC patients.Specifically,patients with IL-17D high expression had a median PFS of 3.1 months compared with 6.5 months in low ex-pression patients[95%confidence interval(CI)(1.178,3.655),P=0.009].Similarly,the median OS was 9.8 months in the high expression group versus 21.8 months in the low expression group[95%CI(1.116,4.392),P=0.018].ROC curve showed that the prediction performance was favorable[AUCPFS=0.702,95%CI(0.562,0.842),P=0.027;AU-COS=0.684,95%CI(0.550,0.818),P=0.014].Although IL-11 and IL-36A alone were not significant predictors of PFS and OS in NSCLC patients,the median PFS and OS were notably shortened to 2.2 months(P=0.003)and 3.0 months(P<0.001),respectively,when high expression of IL-11 and IL-36A was combined with high expression of IL-17D.The ROC curve analysis demonstrated an improvement in prediction efficiency for both PFS and OS in NSCLC patients[AUCPFS=0.748,95%CI(0.615,0.880),P=0.007;AUCOS=0.703,95%CI(0.573,0.833),P=0.007].[Conclu-sion]The results suggest that high expression of IL-11,IL-17D,and IL-36A is associated with a higher risk of disease progression which correlates to poor PFS and OS in NSCLC patients.

ObjectiveTo analyze the characteristics of kidney Yang deficiency syndrome in different stages and time evolution of chronic kidney disease （CKD） to explore the evolution patterns of kidney Yang deficiency syndrome in CKD. MethodThe evidence information of 256 patients with CKD was collected from October 2020 to September 2022 according to relevant standards， and the "Kidney Yang Deficiency Syndrome Evaluation Scale for Chronic Kidney Disease" was developed. With SPSS Statistics 20.0， SPSS Modeler 18.0， Gephi 0.9.2， and R 4.2.1， the syndrome information of CKD patients at various stages and the syndrome changes after one year were statistically analyzed using complex network analysis， association rule analysis， probability transition matrix analysis， and chi-square test， and the kidney Yang deficiency syndrome of patients at various stages was comprehensively evaluated. ResultIn the CKD population， the proportion of females with kidney Yang deficiency syndrome was higher than that of males （P<0.01）， and the proportion of people over 65 years old was higher than in people under 65 years old. The proportion of people with kidney Yang deficiency syndrome increased with the progression of kidney disease， and the proportion of Ⅳ-Ⅴ CKD patients with kidney Yang deficiency syndrome was higher than that of Ⅰ-Ⅱ CKD patients （P<0.01）. From Ⅰ CKD to Ⅴ CKD， the frequency of dull tongue continued to increase， and the frequency of enlarged tongue and tooth-marked tongue continued to increase after Ⅲ CKD. The frequency of thick coating and greasy coating ranked in the top 3 of frequency distribution in Ⅴ CKD. After Ⅲ CKD， the top 3 tongue characteristics were weak pulse， deep pulse， and thready pulse， all of which were characteristics of kidney Yang deficiency syndrome. Complex network analysis of the tongue and pulse showed that the core tongue and pulse characteristics of patients with end-stage CKD were tooth-marked tongue with white coating and deep and thready pulse. The results of symptom frequency analysis and complex network analysis showed that aversion to cold and preference for warmth， weakness of the knees， and cold extremities were the top 3 symptoms in Ⅰ-Ⅲ CKD patients with kidney Yang deficiency syndrome， and in Ⅳ-Ⅴ CKD， the manifestations of the syndrome of Yang deficiency and water diffusion， such as drowsiness and fatigue， edema， and frequent urination at night became characteristic symptoms. The scores of edema， pale complexion， soreness and weakness of the waist and knees， loose stools， and mental depression symptoms， as well as the total score of kidney Yang deficiency syndrome gradually increased with disease progression， with statistical differences between different stages of CKD （P<0.05， P<0.01）. The frequency analysis of disease-related syndrome elements showed that the frequencies of Yang deficiency syndrome， phlegm-dampness syndrome， blood stasis syndrome， and turbidity-toxin syndrome gradually increased with disease progression， and there were statistically significant differences in the distribution between different stages of CKD （P<0.05， P<0.01）. The results of complex network analysis showed that Yang deficiency syndrome was the core syndrome element throughout all stages of CKD and was the main syndrome element type of CKD， while phlegm-dampness syndrome， blood stasis syndrome， and turbidity-toxin syndrome were gradually revealed in the middle and late stages of CKD. In the CKD population with kidney-Yang deficiency syndrome， the distribution of phlegm-dampness syndrome， blood stasis syndrome， and turbidity-toxin syndrome as concurrent syndromes in different CKD stages had statistically significant differences （P<0.05， P<0.01）. The association rule analysis showed that as the disease progressed， associations between the concurrent syndromes， such as phlegm-dampness syndrome， blood stasis syndrome， turbidity-toxin syndrome， and fluid retention syndrome， and kidney-Yang deficiency syndrome were gradually enhanced. The comparison of the changes in CKD with kidney Yang deficiency syndrome within one year showed that the disease location was centered on the kidney and transmitted between the spleen， stomach， heart， and liver. There is a 23.81% probability of kidney-Yang deficiency syndrome transforming into Qi deficiency syndromes （Qi deficiency in the spleen and kidney， Qi deficiency in the liver， and Qi deficiency in the heart）， 23.79% into Yin deficiency syndromes （Yin deficiency in the liver and kidney， Qi and Yin deficiency， and Yin deficiency in the liver and stomach）， and 9.52% into dampness syndromes （phlegm-dampness internal obstruction and wind-dampness obstruction）. In contrast， 20% of spleen and kidney Qi deficiency syndrome transformed into kidney Yang deficiency syndrome， and 33.33% of Qi deficiency and blood stasis syndrome transformed into kidney Yang deficiency syndrome. ConclusionAs Ⅰ CKD progresses to Ⅴ CKD， the severity of kidney Yang deficiency syndrome gradually increases， and the syndrome characteristics of kidney Yang deficiency become pronounced. Furthermore， the pathogenic factors， such as phlegm-dampness， blood stasis， and turbidity-toxin， gradually increase. With the change of time， kidney Yang deficiency syndrome in CKD tends to evolve into syndromes related to Qi deficiency， Yin deficiency， and dampness. The discovery of these rules provides a theoretical basis and reference guidance for the treatment of CKD based on syndrome differentiation.
