ObjectiveTo analyze the diversity and structural characteristics of microbial communities in the rhizosphere soil of healthy and diseased Andrographis paniculata and to explore the interactions of soil, plants, and microorganisms during the occurrence of diseases. MethodsThe physicochemical properties of the rhizosphere soil of healthy and diseased A.paniculata were determined, and the composition and diversity of bacterial and fungal communities in the rhizosphere soil were analyzed by Illumina high-throughput sequencing. Furthermore, the correlations between physicochemical properties and microorganisms of the rhizosphere soil were explored. ResultsThe content of total nitrogen, total potassium, and available potassium in the rhizosphere soil of diseased A. paniculata was significantly higher than that of healthy A. paniculata. The alpha diversity and richness (operational taxonomic units) of bacterial and fungal communities in the rhizosphere soil of diseased plants decreased compared with those of healthy plants. The microbial communities in the rhizosphere soil of healthy and diseased A. paniculata showed similar composition but different relative abundance. At the phylum level, the relative abundance of Proteobacteria and Chytridiomycota significantly increased, while that of Bacteroidota significantly decreased in the rhizosphere soil of diseased plants. At the genus level, the relative abundance of Sphingomonas, Pseudomonas, and Bryobacter significantly increased, while that of RB41 showed a significant decrease in the rhizosphere soil of diseased plants. The correlation analysis showed different correlations of microbial phyla with physicochemical properties of the rhizosphere soil between healthy and diseased plants. Organic matter, alkaline nitrogen, available phosphorus, and total potassium were correlated with the relative abundance of some dominant bacterial and fungal phyla in the rhizosphere soil of healthy plants, while available nitrogen and total phosphorus were correlated with the relative abundance of some dominant bacterial and fungal phyla in the rhizosphere soil of diseased plants. ConclusionThere are differences in the diversity and richness of microbial communities in the rhizosphere soil of healthy and diseased A. paniculata. The physicochemical properties of soil may have an impact on the rhizosphere microorganisms of A. paniculata, leading to the development of diseases. The results provide a scientific basis for the prevention and ecological management of A. paniculata diseases.

ObjectiveTo observe the clinical efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia. MethodsIn this study, hyperlipidemia patients treated in the Hospital of Chengdu University of Traditional Chinese Medicine (TCM) from September 2022 to December 2023 were randomly assigned into a control group and an observation group. Finally, 162 valid cases were included, encompassing 74 cases in the control group and 88 cases in the observation group. The control group was treated with atorvastatin calcium tablets, and the observation group with atorvastatin calcium tablets + Zhuyuwan extract granules. Both groups were treated for 8 weeks. The efficacy in terms of blood lipid level recovery, blood lipid levels, TCM syndrome distribution, efficacy in terms of TCM syndrome, and TCM symptom scores were compared between the two groups as well as between before and after treatment. Liver and kidney functions were monitored for safety assessment. ResultsIn terms of blood lipid level recovery, the total response rate in the observation group was 86.36% (76/88) and that in the control group was 86.49% (64/74), with no statistically significant difference between the two groups. After treatment, both groups showed declines in levels of triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) (P<0.05) and elevations in the level of high-density lipoprotein cholesterol (HDL-C) (P<0.05). Moreover, the observation group outperformed the control group in recovering the levels of TG, LDL-C, and HDL-C (P<0.05, P<0.01). In terms of TCM syndrome, hyperlipidemia was mostly caused by phlegm turbidity and obstruction. The total response rate in terms of TCM syndrome in the observation group was 87.30% (55/63), which was higher than that (63.46%, 33/52) in the control group (χ2=9.102, P<0.01). After treatment, the scores of total TCM symptoms, primary symptoms, and secondary symptoms decreased in both groups (P<0.05), and the observation group had lower scores than the control group (P<0.01). The observation group was superior to the control group in alleviating obesity, chest tightness, and low food intake (P<0.05). In terms of safety, the level of aminotransferase was slightly elevated in the control group, and no obvious adverse reaction was observed in the observation group, with no statistical significance in the incidence of adverse reactions. ConclusionZhuyuwan combined with atorvastatin can not only recover blood lipid levels and alleviate TCM symptoms but also reduce the occurrence of adverse reactions.

ObjectiveThe theory of homotherapy for heteropathy is one of the classical rules in traditional Chinese medicine. Taking this theory as a breakthrough point, this study employed gas chromatography-mass spectrometry (GC-MS) to elucidate the mechanism underlying the therapeutic effects of Zhuyuwan on both intrahepatic cholestasis (IC) and ulcerative colitis (UC) from the viewpoint of serum metabolic homeostasis. MethodsThe rat models of α-naphthylisothiocyanate (ANIT)-induced cholestasis and 2,4,6-trinitro-benzenesulfonic acid (TNBS)-induced UC were treated with low (0.6 g·kg-1) and high (1.2 g·kg-1) doses of Zhuyuwan by gavage. In the experiment regarding IC, 24 Sprague-Dawley (SD) rats were randomly assigned into four groups: normal, ANIT model, low-dose Zhuyuwan, and high-dose Zhuyuwan. In the experiment regarding UC, 24 SD rats were randomly allocated into four groups: normal, TNBS model, low-dose Zhuyuwan, and high-dose Zhuyuwan. Firstly, the two disease models and the intervention effects of Zhuyuwan on the two diseases were evaluated based on serum levels of biochemical indicators [alanine aminotransferase (ALT), aspartate transaminase (AST), γ-glutamyltranspeptidase (γ-GT), and total bile acid (TBA)], colon damage score, colon weight index, disease activity index, and histopathological changes in rats. Secondly, the rat serum samples were analyzed by gas chromatography-mass spectrometry (GC-MS) to screen the common core pathways of the two disease models, and the expression of core genes in the pathways was determined by Real-time PCR, on the basis of which the biological mechanism of the treatment of the two disease models by Zhuyuwan was ultimately elucidated. ResultsThe results of the experiment regarding IC showed that the ANIT model group had higher ALT, AST, γ-GT, and TBA levels than the normal group (P<0.01). Compared with the ANIT model group, the low-dose Zhuyuwan group showed declined ALT and TBA levels (P<0.01) and the high-dose Zhuyuwan group showed lowered ALT, TBA, AST, and γ-GT levels (P<0.01). The results of the experiment regarding UC showed that compared with the normal group, the TNBS model group presented increases in the colonic damage score, colon weight index, and disease activity index (P<0.01). Compared with the TNBS model group, the low-dose Zhuyuwan group showcased declines in colon weight index (P<0.01) and disease activity index (P<0.05), and the high-dose Zhuyuwan group showed reductions in the colon damage score, colon weight index, and disease activity index (P<0.01). GC-MS metabolomics analysis combined with qRT-PCR demonstrated that Zhuyuwan had a similar inverse regulatory effect on arginine metabolism disruption in the above two disease models. ConclusionZhuyuwan exhibited definite therapeutic effects on both IC and UC, and the regulation of arginine biosynthesis pathway is the core mechanism for the treatment of both diseases by Zhuyuwan.

ObjectiveTo investigate pulmonary function levels and associated influencing factors among rural elderly in Guangzhou, to identify high-risk populations for poor pulmonary function, and to reveal the relationship between the influencing factors of pulmonary function. MethodsWe recruited 1 500 residents aged 60 to 94 years from rural area of Conghua District, Guangzhou City using convenience sampling in 2023. Data on demographics, body measurements, medical history and lifestyle were collected via face-to-face questionnaires and physical examination. Meanwhile, expiratory function parameters including forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC, and the prevalence of airflow obstruction (AFO) were assessed using a portable spirometer. Age and sex distribution of pulmonary function in older adults at 5-year intervals was reported, and risk factors of AFO using multifactorial logistic regression models were analyzed. Furthermore, path analysis was further employed to explore the role of lifestyle in the association between other influencing factors and lung function. ResultsAmong the 1 500 participants, the median age was 71 years (67-75), and 44.2% were male. Subjects identified as AFOs were generally older, more likely male, less educated, and had lower rates of moderate to vigorous physical activity (<1 time/week) and lower lean body mass. Mean FEV1/FVC ratio was (82.0±16.4) %. FEV1/FVC was (79.80±17.58) % in men and (83.66±15.22) % in women. Older age, lower education, male sex and leanness were negatively associated with all pulmonary function outcomes (all P values<0.05). Path analysis identified that age, gender, marital status, occupation and income may influence pulmonary function indirectly through lifestyle. ConclusionRural elderly in Guangzhou exhibited lower pulmonary function levels, and male sex, non-married status, advanced age, lower education, smoking habits, insufficient engagement in moderate to vigorous physical activity, and lean body type were all associated with worse pulmonary function.

The integrated medical and elderly care model provides comprehensive medical and elderly care services by establishing medical facilities in elderly care institutions or forming close cooperative relationships with surrounding medical institutions. Currently, there are 87,000 paired partnerships established nationwide between medical and health institutions and elderly care service institutions, and more than 7,800 integrated medical and elderly care institutions have obtained the qualifications of medical and health institutions and completed elderly care service registration. This model not only meets the elderly’s healthcare needs but also provides life care, psychological support, and social activities, thereby improving their quality of life. However, the integrated medical and elderly care model also faces numerous ethical dilemmas in practice. This paper aimed to explore in depth the ethical dilemmas and countermeasures optimization in the work of elderly care institutions under this model, to promote the improvement of service quality, comprehensively guarantee the rights and interests of the elderly, and promote the healthy development of this model in practice. Under this model, the elderly care institutions not only bear the responsibility of providing long-term care and life services but also need to cooperate with medical institutions to provide healthcare and health management services for the elderly. By exploring the practical paths for elderly care institutions to address the ethical dilemmas faced with this model, feasible solutions were proposed to enhance the welfare of the elderly and promote the harmonious development of society.

ObjectiveTo explore the clinical features and causative genes of short stature children with unknown etiology, providing evidence for precise clinical diagnosis and treatment. MethodsThe study recruited children with suspected but undiagnosed short stature from the pediatric endocrinology department in our hospital between January 2018 and August 2022. A retrospective analysis was performed on the clinical manifestations, laboratory test and whole exome sequencing (WES) results. Causative genes were classified and analyzed according to different pathogenic mechanisms. ResultsA total of 48 children (30 boys and 18 girls) were enrolled, aged 7.73 ± 3.97 years, with a height standard deviation score ( HtSDS) of -3.63 ± 1.67. Of the patients, 33 (68.8%) suffered from facial anomalies, 31 (64.6%) from skeletal abnormalities, 26 [54.2%, 61.5% of whom born small for gestational age (SGA)] from perinatal abnormalities, 24 [50.0%, 87.5% of whom with growth hormone (GH) peak concentration below normal] from endocrine disorders and 21(43.8%) had a family history of short stature. Laboratory tests showed that GH peak concentration following stimulation test was (9.72 ± 7.25) ng/mL, IGF-1 standard deviation score was -0.82 ± 1.42, the difference between bone age and chronological age was -0.93 ± 1.39 years. Of the 25 cases with mutant genes found by WES, 14 (56.0%) had pathogenic mutation, 6 (24.0%) likely pathogenic mutation, and 5 (20.0%) mutation of uncertain significance. Pathogenic and likely pathogenic variants were identified in 14 genes, including 10 affecting intracellular signaling pathways (PTPN11, RAF1, RIT1, ARID1B, ANKRD11, CSNK2A1, SRCAP, CUL7, SMAD4 and FAM111A) and 4 affecting extracellular matrix (ECM) components or functions (ACAN, FBN1, COL10A1 and COMP). ConclusionsA rare monogenic disease should be considered as the possible etiology for children with severe short stature accompanied by facial anomalies, disproportionate body types, skeletal abnormalities, SGA, GH peak concentration below normal and a family history of short stature. WES played an important role in identifying the monogenic causes of short stature. This study indicated that affecting growth plate cartilage formation through intracellular signaling pathways and ECM components or functions was the main mechanism of causative genes leading to severe short stature in children. Further research may help discover and study new pathogenic variants and gene functions.

Chemotherapy-induced complications, particularly lethal cardiovascular diseases, pose significant challenges for cancer survivors. The intertwined adverse effects, brought by cancer and its complication, further complicate anticancer therapy and lead to diminished clinical outcomes. Simple supplementation of cardioprotective agents falls short in addressing these challenges. Developing bi-functional co-therapy agents provided another potential solution to consolidate the chemotherapy and reduce cardiac events simultaneously. Drug repurposing was naturally endowed with co-therapeutic potential of two indications, implying a unique chance in the development of bi-functional agents. Herein, we further proposed a novel "trilogy of drug repurposing" strategy that comprises function-based, target-focused, and scaffold-driven repurposing approaches, aiming to systematically elucidate the advantages of repurposed drugs in rationally developing bi-functional agent. Through function-based repurposing, a cardioprotective agent, carvedilol (CAR), was identified as a potential neddylation inhibitor to suppress lung cancer growth. Employing target-focused SAR studies and scaffold-driven drug design, we synthesized 44 CAR derivatives to achieve a balance between anticancer and cardioprotection. Remarkably, optimal derivative 43 displayed promising bi-functional effects, especially in various self-established heart failure mice models with and without tumor-bearing. Collectively, the present study validated the practicability of the "trilogy of drug repurposing" strategy in the development of bi-functional co-therapy agents.
