ObjectiveTo identify the pathogen species responsible for the wilt disease of Tetradium ruticarpum in Chongqing, investigate there biological characteristics, and screen effective fungicides, so as to provide a theoretical basis for disease control in production. MethodsThe pathogen was isolated via the tissue culture method. Pathogenicity was verified according to Koch's postulates. The pathogen was identified based on morphological characteristics and multi-gene phylogenetic analysis. The mycelial growth rate method was used for biological characterization of the pathogen and fungicide screening. ResultsThe pathogen colonies were nearly circular with irregular edges, white, short, velvety aerial hyphae, and pale purple undersides. Macroconidia were colorless, sickle-shaped, with 3-5 septa, while microconidia were transparent, elliptical, aseptate or with 1-2 septa. Multi-gene phylogenetic analysis showed that the pathogen clustered in the same clade as Fusarium fujikuroi with 100% support, which, combined with morphological characteristics, identified the pathogen causing wilt of T. ruticarpum in Chongqing as F. fujikuroi. The optimal conditions for the mycelial growth of F. fujikuroi were mung bean agar (MBA) with glucose as the carbon source, beef extract and yeast powder as nitrogen sources, 28 ℃, pH 7.0, and alternating light/dark conditions. The optimal conditions for sporulation were potato dextrose agar (PDA) with glucose as the carbon source, beef extract as the nitrogen source, 28 ℃, pH 7.0, and complete darkness. Among chemical fungicides, phenazine-1-carboxylic acid exhibited the strongest inhibitory effect on F. fujikuroi. Shenqinmycin and tetramycin were the most effective bio-fungicides. ConclusionThis study is the first to report F. fujikuroi as the causal agent of wilt disease in T. rutaecarpa. The chemical fungicide phenazine-1-carboxylic acid and the bio-fungicides shenqinmycin and tetramycin showed strong inhibitory effects against F. fujikuroi.

Diabetic cardiomyopathy (DCM) is one of the most common complications of diabetes mellitus and is a major threat to global health. As a key mechanism in the occurrence and progression of DCM, the inflammatory response persists throughout the entire course of the DCM. The Gaozhuo theory suggests that the basic pathogenesis of inflammatory injury in DCM is the Qi deficiency of spleen and kidney and Gaozhuo invasion, and divides the pathological process into three phases: Gaozhuo invasion, turbid heat damage to the channels, and turbid blood stasis and heat junction. Among them, the Qi deficiency of spleen and kidney and the endogenous formation of Gaozhuo represent the process of inflammatory factor formation induced by glucose metabolism disorders. Turbid heat damage to the channels refers to the process of myocardial inflammatory injury mediated by inflammatory factors, and turbid blood stasis and heat junction are the process of myocardial injury developing toward myocardial fibrosis and ventricular remodeling. As the disease continues to progress, it eventually develops into a depletion of the heart Yang, leading to the ultimate regression of heart failure. According to the theory of Gaozhuo, traditional Chinese medicine (TCM) should regulate inflammatory injury in DCM by strengthening the spleen and tonifying the kidney to address the root cause, and resolving dampness and lowering turbidity to treat the symptoms. If the turbidity has been stored for a long time and turns into heat, strengthening the spleen and tonifying the kidney, and clearing heat and resolving turbidity should be the therapy. If the turbidity, stasis, and heat are knotted in the heart and collaterals, strengthening the spleen and tonifying the kidney, and resolving stasis and lowering turbidity should be the therapy. TCM compounds and monomers can regulate the inflammatory response in DCM. TCM compounds can be divided into the categories for benefiting Qi to resolve turbidity, benefiting Qi and clearing heat to resolve turbidity, and benefiting Qi and activating blood to reduce turbidity. The compounds can inhibit upstream signals of inflammation and expression of inflammatory factors, improve the inflammatory damage to myocardium and blood vessels, myocardial fibrosis, and cardiac systole and diastole, and thus slow down the onset and progression of DCM.

With the aging of the global population, osteoporosis (OP) is becoming a major public health concern worldwide. Currently, the commonly used anti-osteoporosis drugs in clinical practice have limited application due to many side effects. Therefore, developing more effective and safer strategies for the prevention and treatment of OP has become a research focus in this field. In recent years, the clinical efficacy and advantages of traditional Chinese medicine (TCM) in treating OP have been gradually recognized. With the deepening pharmacological research on TCM for OP prevention and treatment, it is found that the active ingredients of Scutellaria baicalensis can promote bone formation or inhibit bone resorption by regulating signaling pathways, including Wnt/β-catenin, osteoprotegerin (OB)/receptor activator of nuclear factor-κB ligand (RANKL)/RANK (OPG/RANKL/RANK), and bone morphogenetic protein 2 (BMP-2)/Smad, mitogen-activated protein kinase (MAPK), and mammalian target of rapamycin (mTOR). However, existing research on active ingredients of S. baicalensis for OP treatment is scattered, making it difficult for scholars to gain a systematic understanding of its research and application. This review summarized the literature on the active ingredients of S. baicalensis in OP treatment worldwide, clarified their mechanisms of action, and explored some issues, providing references for the integration of TCM in OP prevention and treatment.

ObjectiveTo explore the mechanism by which the ethanol extract of Epimedium brevicornu (EEBM) intervenes in mesenchymal adipose-derived stem cells (ADSCs) to delay aging in castrated rats. MethodsForty-five 3-month-old SPF female SD rats were ovariectomized and randomly divided into model group, ADSCs treatment group, and ADSCs groups treated with low, medium, and high concentrations of EEBM (1, 50, 100 μg·L-1), referred to as the AE low, medium, and high concentration groups, with 9 rats in each group. After tail vein injection of 200 μL of the corresponding stem cell suspension, aging-related indicators including cyclin-dependent kinase inhibitor (p21), tumor suppressor gene (p53), interleukin-6 (IL-6), interleukin-8 (IL-8), superoxide dismutase (SOD), malondialdehyde (MDA), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cysteine-aspartic acid protease-3 (Caspase-3), and lipofuscin were measured using enzyme-linked immunosorbent assay (ELISA) and Western blot. ResultsCompared with the model group, the IL-6 content in the AE low, medium, and high concentration groups was significantly decreased (P<0.05). Lipofuscin, MDA, and IL-8 levels in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.01), while SOD content was significantly increased (P<0.05, P<0.01). Compared with the ADSCs treatment group, lipofuscin and IL-8 levels in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01). The MDA content was significantly decreased in the AE medium concentration group (P<0.01). Compared with the model group, protein levels of p21, p53, Bax, and Caspase-3 in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), while the Bcl-2 protein level was significantly increased (P<0.01). Compared with the ADSCs treatment group, protein levels of p21, p53, Bax, and Caspase-3 in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), and the Bcl-2 protein level in the AE low concentration group was significantly increased (P<0.01). ConclusionThe results of this experiment show that EEBM-treated ADSCs or ADSCs may delay aging in castrated rats by inhibiting cell apoptosis, reducing cell cycle inhibitors and pro-inflammatory factors, enhancing antioxidant capacity, and reducing oxidative reactions. Moreover, EEBM-treated ADSCs demonstrate stronger anti-aging effects than ADSCs alone. This study provides experimental evidence supporting the clinical use of EEBM to intervene in ADSCs and delay aging.

ObjectiveTo evaluate the clinical efficacy and safety of Qidan Tangshen Granules (芪丹糖肾颗粒, QTG) in the treatment of early diabetic kidney disease (DKD) with qi deficiency, blood stasis, and kidney deficiency syndrome, and to explore its mechanism. MethodsA double-blind, double-simulated method was used to enroll 200 patients with early DKD and qi deficiency, blood stasis, and kidney deficiency syndrome. Patients were randomly assigned in a 1∶1 ratio to the treatment group (100 cases) and the control group (100 cases). The treatment group received QTG plus a valsartan capsule simulant, while the control group received valsartan capsules plus a QTG simulant, both for 12 weeks. The primary outcome was the urinary albumin-to-creatinine ratio (UACR). Secondary outcomes included estimated glomerular filtration rate (eGFR), fasting blood glucose (FBG), 2-hour postprandial blood glucose (PBG), glycated hemoglobin (HbA1c), and traditional Chinese medicine (TCM) syndrome scores (including individual symptom scores for fatigue, dull complexion, soreness and weakness of the waist and knees, headache and chest pain, irritability, spontaneous sweating, thirst and polydipsia, polyphagia, polyuria, numbness of the limbs, and the total TCM syndrome score). Oxidative stress markers including serum 8-hydroxy-2'-deoxyguanosine (8-OHDG), 3-nitrotyrosine (3-NT), and superoxide dismutase (SOD) were also assessed. Clinical efficacy and TCM syndrome efficacy were evaluated after treatment, and routine blood tests, urinalysis, and liver function tests were conducted and adverse reaction during the tria was recorded to assess safety. ResultsA total of 191 patients completed the study (95 in the treatment group and 96 in the control group). The treatment group showed significant reductions in UACR, FBG, PBG, and HbA1c levels after treatment (P<0.05 or P<0.01). The single TCM symptom scores except for polyphagia and total TCM syndrome scores significantly decreased (P<0.05 or P<0.01). Compared to the control group, the treatment group had signi-ficantly lower UACR, FBG, PBG levels, and total TCM syndrome scores, sinlge symptoms scores except for polyphagia and limb numbness (P<0.05 or P<0.01). Among 40 randomly selected patients (21 cases in the treatment group and 19 cases in the control group) for oxidative stress analysis, there were no significant differences in SOD, 3-NT, and 8-OHDG levels before and after treatment within or between groups (P>0.05). The overall effective rate in the treatment group was 64.2% (61/95) and 39.6% (38/96) in the control group, while the TCM syndrome efficacy rates were 80.0% (76/95) and 24.0% (23/96), respectively, with the treatment group showing superior efficacy (P<0.01). No significant differences were observed in routine blood tests, urinalysis, or liver function indices before and after treatment in either group (P>0.05). The incidence of adverse reactions was 8.4% (8/95) in the treatment group and 9.4% (9/96) in the control group, with no statistically significant difference (P>0.05). ConclusionQTG can effectively reduce UACR and blood glucose levels, alleviate clinical symptoms, and improve clinical efficacy in patients with early DKD with qi deficiency, blood stasis, and kidney deficiency syndrome. The treatment is well-tolerated and safe, with no significant impact on oxidative stress markers.

ObjectiveTo investigate the optimal ratio of goat horn replacing antelope horn in Fufang Lingjiao Jiangya pills and the blood pressure-lowering mechanism of this medicine. MethodsThe blood pressure-lowering efficacy of Fufang Lingjiao Jiangya pills with varying proportions of goat horn replacing antelope horn was evaluated on spontaneous hypertensive rats (SHR). In this experiment, 50 SHR rats were randomly grouped as follows: model (n=8), captopril (0.01 g·kg-1) (n=6), low-dose blank Fufang Lingjiao Jiangya pills (0.342 g·kg-1) (n=6), high-dose blank Fufang Lingjiao Jiangya pills (0.684 g·kg-1) (n=6), low-dose antelope horn-containing Fufang Lingjiao Jiangya pills (0.378 g·kg-1) (n=6), high-dose antelope horn-containing Fufang Lingjiao Jiangya pills (0.756 g·kg-1) (n=6), low-dose goat horn-containing Fufang Lingjiao Jiangya pills (0.378 g·kg-1) (n=6), and high-dose goat horn-containing Fufang Lingjiao Jiangya pills (0.756 g·kg-1) (n=6). Additionally, 8 WKY rats were used as the normal group. Drugs were administered by gavage for 4 weeks while an equal volume of distilled water was administered for the normal and model groups. Blood pressure was measured before administration, 3 h post administration, and biweekly thereafter. In the experiment for Fufang Lingjiao Jiangya pills with goat horn replacing antelope horn in different proportions, 48 SHR rats were randomly grouped as follows: model, blank Fufang Lingjiao Jiangya pills (0.684 g·kg-1), antelope horn-containing Fufang Lingjiao Jiangya pills (0.756 g·kg-1), 2× goat horn-containing Fufang Lingjiao Jiangya pills (0.824 g·kg-1), 4× goat horn Fufang Lingjiao Jiangya pills (0.969 g·kg-1), and 6× goat horn Fufang Lingjiao Jiangya pills (1.112 g·kg-1). The normal group included 8 WKY rats, and the normal group and model group received an equal volume of distilled water. The treatment lasted for 2 weeks, and blood pressure was recorded at various time points (pre-administration, 3 h post administration, and on days 4, 7, 10, and 14 of administration). Serum levels of angiotensin-converting enzyme (ACE), angiotensin Ⅱ(Ang Ⅱ), renin, and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay. Histopathological changes in the heart, kidney, and thoracic aorta were observed by hematoxylin-eosin staining. The protein levels of ACE2, angiotensin Ⅱ type 1 receptor (AT1R), and angiotensinogen (AGT) in the kidney tissue were determined by Western blot, while the expression of nuclear factor (NF)-κB p65 and Toll-like receptor 4 (TLR4) in the thoracic aorta tissue was assessed by immunohistochemistry. ResultsCompared with the model group, all treatment groups showed lowered blood pressure (P<0.05, P<0.01), and the 6× goat horn-containing Fufang Lingjiao Jiangya pills group showed consistent blood pressure-lowering effect with the antelope horn-containing Fufang Lingjiao Jiangya pills group. Compared with the normal group, the model group showed elevated serum levels of ACE, Ang Ⅱ, renin, and IL-6, while the elevations were declined in the Fufang Lingjiao Jiangya pills groups (P<0.05, P<0.01). Pathological changes in the heart, kidney, and thoracic aorta were alleviated in all the treatment groups, with the 6× goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups exhibited the best effect. Western blot and immunohistochemistry results showed that all the treatment groups exhibited down-regulated protein levels of AT1R, AGT, NF-κB p65, and TLR4 and up-regulated protein levels of ACE2 (P<0.05, P<0.01) compared with model group, with the 6×goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups showcasing the best effect. ConclusionReplacing antelope horn with 6×goat horn in Fufang Lingjiao Jiangya pills can achieve consistent blood pressure-lowering effect with the original prescription. The prescription may exert the effect by inhibiting the renin-angiotensin-aldosterone system (RAAS) and TLR4/NF-κB signaling pathways.

OBJECTIVE To establish management index system for rational drug use of key monitoring drugs, and provide reference for the management of key monitoring drugs in the hospitals. METHODS First, the management index system for rational drug use of key monitoring drugs was drafted by collecting the evidence from related medical literature. Next, using a modified Delphi method, twenty experienced experts from the fields of pharmacy, medical practice, healthcare insurance, and finance were selected to participate in two rounds of questionnaire consultations. Based on the expert enthusiasm coefficient, authority coefficient, degree of opinion concentration, and degree of coordination, the final indicators were determined to establish a management index system for rational drug use of key monitored drugs in medical institutions. RESULTS The expert enthusiasm coefficients reached 100% in both rounds of consultation. In first-level, second-level and third-level indicators, the authority coefficients of experts were 0.89, 0.86 and 0.87, and coordination coefficients of the experts in importance score were 0.300 (P< 0.05), 0.125 (P<0.05) and 0.139 (P<0.05), respectively. The average score for the importance of all indicators reached over 3.5, in which the full score ratio ranged from 35% to 100%. Except that the variation coefficient of a third-level indicator “number of specifications purchased for key monitored drugs” was 0.26, the variation coefficients of rest indicators were less than or equal to 0.25. Based on the results of expert consultation, final version of the management index system established in this study, including two first-level indicators (drug procurement and use, and rational drug use), five second-level indicators (such as the accessibility, cost-effectiveness) and twenty third-level indicators (such as the number of specifications purchased for key monitored drugs, the increase in the cost of key monitored drugs). CONCLUSIONS The management index system established in this study possesses high reliability and strong operability, and may provide a reference for the management of key monitoring drugs in the hospitals.
