Bronchial asthma （asthma） is a heterogeneous disease characterized by airflow limitation， airway remodeling， and recurrent symptoms such as wheezing， shortness of breath， chest tightness， and cough. Its prevalence is gradually increasing， and a portion of patients are still poorly controlled， leading to a serious social and medical burden. Modern studies have proposed the concept of the "lung-gut axis"， which is based on the crosstalk between microorganisms and their metabolites in the lungs and large intestine， and have indicated that microbial dysbiosis in these organs may affect the onset and progression of asthma. Traditional Chinese medicine （TCM） has found the phenomenon of lung-intestinal comorbidity and put forward the importance of "lung-intestinal coordination therapy" in the treatment of lung-related diseases. It has been found that intestinal flora and their metabolites can modulate immune responses through the lung-gut axis， demonstrating great potential for predicting asthma susceptibility， anticipating phenotypes， assessing asthma severity， and guiding treatment. TCM comopunds that embody lung-intestinal coordination therapy， including herbal formulas， single herbs， acupuncture， moxibustion， acupoint application， and spinal pinching therapy， has been shown to regulate intestinal flora， improve metabolism， regulate immunity， alleviate lung inflammation， reduce mucus secretion， inhibit airway remodeling， effectively alleviate symptoms， and delay lung function decline. Based on "lung-intestinal coordination therapy"， this paper used intestinal flora as the entry point to summarize the underlying mechanisms of TCM in asthma treatment and highlighted the pivotal role of intestinal flora in asthma， providing a new idea for its clinical treatment through the intestinal flora .

This study aimed to construct an evidence map and conduct a comprehensive analysis of clinical research literature on the treatment of pulmonary fibrosis with proprietary Chinese medicines published over the past three decades, so as to systematically evaluate the effectiveness and limitations of existing evidence and provide a scientific basis for subsequent clinical practice, research directions, and policy-making. A systematic search was conducted across 7 databases in both Chinese and English from the inception of the databases to June 1, 2024. The clinical research characteristics and methodological quality of the included literature were assessed. A total of 123 pieces of literature were ultimately included, comprising 108 interventional studies, 3 observational studies, 10 secondary study, and 2 expert consensuses. These studies involved 33 kinds of proprietary Chinese medicines, with Danhong Injection being the most widely used. Most studies had a duration of 1-3 months and a sample size ranging from 50 to 100 cases, and they were often used in combination with steroids or conventional western medicine. There was a common phenomenon of off-label use of proprietary Chinese medicines. The main outcome indicators included pulmonary function, blood gas analysis, and total effective rate, with issues such as insufficient safety reporting, lack of distinctive traditional Chinese medicine(TCM) features, absence of long-term outcome indicators, and strong subjective evaluation. In terms of methodological quality assessment, randomized controlled trial(RCT) had biases in randomization and outcome indicator measurement and a risk of selective reporting. Meta-analysis lacked reporting on protocol registration, literature exclusion lists, and disclosure of conflicts of interest. Expert consensuses lacked standards in terms of rigor, scientific basis, and applicability. The quality of clinical research evidence on the treatment of pulmonary fibrosis with proprietary Chinese medicines urgently needs improvement. It is recommended that future research should pay more attention to the scientific and rigorous design to enhance the standardization and reproducibility of the research. At the same time, it should integrate TCM theories to establish an outcome indicator evaluation system suitable for the treatment of pulmonary fibrosis with proprietary Chinese medicines, so as to fully explore the potential of proprietary Chinese medicines in treating pulmonary fibrosis.

The inflammatory status in patients with chronic kidney disease(CKD)is closely associated with cardiovascular events,infections,and other complications,and is a powerful indicator for prognosis assessment.The core view of the"gut-kidney axis"theory reveals the relationship among inflammatory state,microbiota dysbiosis,and deterioration of renal function.The microbiota alters the microenvironment through structural changes and metabolites with different properties,subsequently leading to microbiota translocation,inducing inflammatory lesions,and damaging the kidneys.Recent studies have proposed that targeted microbiota intervention strategies such as probiotics,prebiotics,and synbiotics can modulate the microbiota structure,regulate the microenvironment,relieve renal inflammation,and affect the progression of renal disease,representing a potentially promising research direction in the future.This review discusses the characteristics of how intestinal microbiota influence the inflammatory status in CKD,focusing on the research progress of targeted microbiota intervention,aiming to discuss the effectiveness and scientific basis of these strategies,providing a foundation for the treatment of CKD and the expansion of targeted microbiota research,as well as offering references for the clinical application of probiotics,prebiotics,and synbiotics.

Objective To investigate the effects of Zhoufei Pingchuan Capsules on the balance of peripheral blood helper T lymphocyte 17 cell/regulatory T lymphocyte cell(Th17/Treg)and related inflammatory factors in peripheral blood of patients with stable chronic obstructive pulmonary disease(COPD)with lung-kidney qi deficiency syndrome.Methods Totally 40 COPD patients were randomly divided into the study group and the control group,with 20 cases in each group.Another 20 cases were in the healthy group.The control group was given tiotropium bromide powder inhalation,18 μg/time,1 time/d,inhalation;on the basis of the control group,the study group was given Zhoufei Pingchuan Capsules,3 pills/time,3 times/d,orally.All patients were treated for 8 weeks.The healthy group was not given any intervention.Forced expiratory volume in one second(FEV1),FEV1/forced vital capacity(FEV1/FVC),maximum mid-expiratory flow(MMEF),carbon monoxide diffusing capacity/alveolar ventilation(DLCO/VA),arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2),COPD assessment test(CAT)score,Th17/Treg ratio,cytokines interleukin(IL)-17,IL-22,IL-10,and transforming growth factor-β1(TGF-β1)were compared before and after treatment.Results Compared with before treatment,the lung function indexes(FEV1,FEV1/FVC,MMEF,DLCO/VA),blood gas indexes(PaO2,PaCO2)and CAT score in the study group after treatment were significantly improved(P<0.05).After treatment,the mean values of MMEF,DLCO/VA,PaCO2 and CAT score in the study group were better than those in the control group(P<0.05).Compared with before treatment,the levels of Th17,IL-17 and IL-22 in the study group were significantly lower,and the levels of Treg,IL-10 and TGF-β1 were significantly higher(P<0.05).After treatment,there were significant differences in Th17,Treg,IL-17,IL-22,IL-10 and TGF-β1 among the three groups(P<0.01).Further pairwise comparison showed that Th17 ranked in the order of high and low was control group>study group>healthy group,Treg in the order of high and low was healthy group>study group>control group,the levels of IL-17 and IL-22 in the order of high and low were control group>study group>healthy group,and the levels of IL-10 and TGF-β1 in the order of high and low were healthy group>study group>control group,with statistical significance(P<0.05).Conclusion Zhoufei Pingchuan Capsules can improve the lung function,arterial blood gas and symptom score of patients with lung-kidney qi deficiency syndrome in stable stage of COPD.Its mechanism may be related to regulating the balance of Th17/Treg,down-regulating the levels of Th17,IL-17 and IL-22,and up-regulating the levels of Treg,IL-10 and TGF-β1,in order to reduce airway inflammation and regulate immune homeostasis.

Acute ST-segment elevation myocardial infarction(STEMI)is one of the main causes of death and disa-bility in the East and the West.Though medical technology develops rapidly,its morbidity and mortality are still high.High mobility group box 1(HMGB1)is a kind of damage associated molecule patterns(DAMPs)that is re-leased from inflammatory cells and necrotic cells,causing inflammatory activation,releasing inflammatory factors,triggering the coagulation cascade,regulating cell migration,chemotaxis,apoptosis and autophagy.This review aims to describe the advances in the mechanism of HMGB1 involved in acute STEMI,and hope to provide new ideas for the prevention,treatment and prognosis improvement of STEMI.

This study was aimed at understanding the pollution distribution pattern of avian influenza virus in the environ-ment in poultry related places in Shandong Province,to provide a scientific basis for the prevention,control,prediction,and early warning regarding human infection with avian influenza.From 2020 to 2023,6 523 environmental samples were collected in 16 cities in Shandong Province from four types of poultry-related places.Fluorescence quantitative PCR was used for nucleic acid testing of influenza A virus.Positive samples were further identified for the H5,H7,and H9 subtypes of avian influenza virus.The epidemiological characteristics of avian influenza viruses in the poultry related environment of Shandong Province were described,and inter-rate comparisons were performed with the x2 test.During 2020-2023,6 523 environmental samples were collected,and 1 007 cases positive for avian influenza virus were detected,with a positivity rate of 15.44％.H5,H7,and H9 subtypesand mixed infections were detected.H9 was the main subtype(88.48％)in positive specimens.A significant difference in positivity rates was observed among regions(x2=431.956,P＜0.001),and the highest positivity rate was 28.93％.Significant differences in positivity rates were observed among monitoring sites(x2=304.604,P＜0.001),sample types(x2=109.678,P＜0.001),and quarters(x2=64.963,P＜0.001).The positive detection rate was highest at monitoring sites in urban and rural live poultry markets(20.12％),and the positive detection rate of samples collected by wiping meat cut-ting board surfaces was higher than that of other samples(22.56％).The peak positive detection rate occurred in spring(20.31％).Widespread contamination with avian influenza virus was observed in poultry environments in Shandong Prov-ince.The H9 subtype,the main pathogen,coexisted with H5 and H7 subtypes,thus posing a risk of human infection with avian influenza.Therefore,prevention and control of avian influenza must be strengthened in key seasons,areas,places,and links.

Trihelix transcription factors play important roles in plant light responses, growth and development, and stress responses. However, Trihelix has not yet been reported in Eucommia ulmoides. In this study, bioinformatics methods were used to comprehensively identify and analyze the expression patterns of the Trihelix gene family in E. ulmoides, aiming to provide a basis for further functional studies of EuGTs genes. A total of 9 Trihelix gene family members were identified in E. ulmoides, encoding proteins with 339 to 883 amino acids, with isoelectric points ranging from 5.13 to 9.39 and relative molecular weights between 36 992.06 and 97 871.61. Subcellular localization results showed that only EuGT-2 was localized in chloroplasts, while the others were located in the nucleus. The Trihelix gene family was categorized into six subfamilies: GT-1, GT-2, SH4, SIP1, GTγ, and GTδ. EuGTs were distributed among three subfamilies: SH4, GT-1, and GT-2, containing 1, 6, and 2 Trihelix proteins, respectively, with 2 to 17 exons. The promoters of EuGTs contained various cis-acting elements related to hormones, stress, photoperiod, and growth and development. Collinearity analysis revealed 5 collinear gene pairs between E. ulmoides and Arabidopsis thaliana, and 14 collinear gene pairs between E. ulmoides and Populus. Expression pattern analysis showed that EuGTs exhibited tissue-specific expression: EuGT-1, EuGT-2 had the highest expression levels in leaves, EuGT-4, EuGT-6, EuGT-9 had the highest transcriptional levels in marginal peel, and EuGT-5、EuGT-8 were predominantly expressed in the xylem. As leaves developed, EuGTs showed a trend of asynchronous changes. No significant differences in EuGTs expression were observed between male and female flowers, with high expression levels mainly during the induction stage of flowering. The qRT-PCR analysis indicated that most EuGTs genes were most highly expressed in the leaves of E. ulmoides, while EuGT-5 was highly expressed in the stems. Under 200 mmol·L~(-1) NaCl treatment, most EuGTs genes exhibited an initial increase followed by a decrease in expression, significantly responding to salt stress. This study provides important genetic resources for further exploration of EuGTs gene functions and germplasm innovation in E. ulmoides.

Objective:To investigate the clinical significance of vertebral body partition in the unipedicular percutaneous vertebroplasty (PVP) for osteoporotic vertebral fractures.Methods:From July 2019 to October 2021, 89 patients with osteoporotic vertebral fracture were treated by unipedicular PVP at Department of Spinal Surgery, Zhengzhou Orthopaedic Hospital. They were 37 males and 52 females, with a mean age of (70.5±4.8) years (from 60 to 80 years). According to the vertebral body partition, the patients were divided into group a (32 cases), group b (20 cases), group c (21 cases), group d (11 cases), group e (0 case) and group f (5 cases). The therapeutic effects were evaluated by comparing the improvement rates of visual analogue scale (VAS) and Oswestry disability index (ODI) between preoperation and postoperative 1-day among all partition groups. The imaging efficacy was evaluated by comparing the proportions of bone cement diffusion area in the posteroanterior and lateral DR films and the leakage of bone cement among all partition groups.Results:The improvement rates of VAS score between preoperation and postoperation: group a [77.8 (75.0, 82.5) %] > group b [71.4 (71.4, 71.4) %] > group c [66.7 (66.7, 66.7) %] > group d [60.0 (60.0, 62.5) %] > group f [57.1 (50.0, 57.1)%], showing a statistically significant difference between any 2 groups ( P<0.001). The improvement rates of ODI score: group a (58.0%±4.2%) > group b (47.5%±2.5%) > group c (42.9%±2.9%) > group d (39.6%±3.2%) > group f (34.2%±8.4%), showing a statistically significant difference between any 2 groups ( P<0.001). The proportions of bone cement diffusion area: group a (76.9%±3.5%) > group b (71.3%±3.1%) > group c (66.1%±3.6%) > group d (60.2%±2.6%) > group f (54.0%±4.2%), showing a statistically significant difference between any 2 groups ( P<0.001). Bone cement leakage occurred in 7 cases, including 3 ones of anterior vertebral leakage (1 case in group a and 2 cases in group b), and 4 ones of leakage into the paravertebral venous plexus (2 cases in group c and 2 cases in group d). There was no intraspinal leakage, or symptoms of nerve compression or lesion. Conclusion:In the unipedicular PVP for osteoporotic vertebral fractures, our vertebral body partition can guide puncturing for bone cement injection because it indicates the optimal and the risky partitions.

AIM:To explore the influence factors of the treatment zone diameter(TZD)and its correlation with axial length growth(ALG)after Paragon CRT orthokeratology.METHODS: Retrospective clinical study. The data of 226 myopic patients(226 eyes)wearing Paragon CRT orthokeratology from April 2020 to September 2022 were collect. The correlated factors of TZD after wearing lens for 1mo, and the relationship between the overlapping treatment zone/ pupil area ratio and the ALG after wearing lens for 1a were analyzed.RESULTS: After wearing lens for 1mo, the TZD was negatively correlated with central corneal thickness(CCT)and positively correlated with the flat corneal eccentricity. After wearing lens for 1a, the ALG of the small TZD group(0.25±0.18mm)was significantly smaller than that of the large TZD group(0.34±0.24mm, P=0.002), and the ALG of the small area ratio group(0.24±0.19mm)was significantly smaller than that of the large area ratio group(0.35±0.23mm,P<0.001). Age and overlapping treatment zone area/pupil area ratio were significantly associated with the ALG in multivariate linear regression(all P<0.05).CONCLUSION: The wearers with thicker CCT and smaller flat corneal eccentricity usually had smaller TZD, and both the TZD and the overlapping treatment zone area/pupil area ratio were correlated with the ALG.

Objective To observe the potential mechanism of electroacupuncture regulating the erythropoietin-producing hepatocellular receptor B2/erythropoietin-producing hepatocellular receptor-interacting B2/big mitogen-activated protein kinase 1(EphB2/EphrinB2/BMK1) signaling pathway to improve neural damage in vascular dementia rats. Methods Eighty SD male adult rats were randomly divided into a sham surgery group, a model group, a non acupoint electroacupuncture group, a nimodipine group, and an electroacupuncture three needle group. The vascular dementia rat model was made by the modified Pulsinelli four vessel occlusion method. After grouping, the rats in each group were subjected to water maze test, HE staining, Nissl staining, and transmission electron microscopy(TEM) to observe the pathological changes in the hippocampal CA1 area, and the expression of EphB2 and BMK1 in the hippocampal CA1 area was detected by immunohistochemistry; Detection of EphB2 and BMK1 protein expression in rat hippocampal CA1 region was detected by Western blotting. Results Compared with the model group, the escape latency of vascular dementia rats treated with electroacupuncture and nimodipine decreased (P<0.05), while the number of crossing platforms significantly increased (P<0.05); The result of HE staining, Nissl staining and TEM showed that compared with the model group, the neurons in hippocampal CA1 area of rats in the EA Zhisanzhen group and nimodipine group were arranged orderly, and the morphology and structure of cells and organelle were complete; Immunohistochemical method and Western blotting showed that the expression of EphB2 and BMK1 in the CA1 region of hippocampus in the model group was significantly lower than that in the sham surgery group (P<0.05); Compared with the model group, the expression of EphB2 and BMK1 in the hippocampal CA1 region of rats in the electroacupuncture Zhisanzhen group significantly increased (P<0.05), while the expression of EphB2 and BMK1 in the hippocampal CA1 region of rats in the non acupoint electroacupuncture group was not statistically significant (P>0.05). Compared with the nimodipine group, the expression of EphB2 and BMK1 in the hippocampal CA1 region of rats in the electroacupuncture Zhisanzhen group significantly increased (P<0.05). Conclusion Electroacupuncture may improve the damage of hippocampal neurons in vascular dementia rats by increasing the expression of EphB2 and BMK1 in the CA1 region of the hippocampus, thereby improving the learning and memory of vascular dementia rats.
