ObjectiveTo investigate the therapeutic effect of Astragali Radix-mediated changes in gut microbiota on treating type 2 diabetes (T2DM). MethodsA 12-week randomized, placebo-controlled clinical trial enrolled eighty patients with newly diagnosed type 2 diabetes and poor glycemic control in the Qi deficiency type. All patients received insulin therapy. The observation group (40 cases) was administered with Astragali Radix Granules, while the control group (40 cases) received a placebo. Both treamtents were taken orally twice daily. Changes in gut microbiota were assessed by 16s rDNA sequencing. Serum glucagon-like peptide-1 (GLP-1) levels were measured using enzyme-linked immunosorbent assay (ELISA). Glucose metabolism indicators including fasting blood glucose (FPG), 2-hour postprandial blood glucose (2 h PG),glycated albumin(GA), and glycated hemoglobin (HbA1c) were evaluated. Pancreatic function was evaluated using fasting C-peptide (FCP), 2-hour postprandial C-peptide (2 h CP), and C-peptide area under the curve (AUCcp). Traditional Chinese medicine (TCM) syndrome scores, clinical efficacy, and safety indicators were also observed. ResultsIn terms of glucose metabolism indicators, compared with the baseline, both groups exhibited significantly lower FPG, 2 h PG, GA and HbA1C (P<0.01),while FCP, 2 h CP and AUCcp were significantly higher (P<0.01). Compared with the control group after the treatment, the observation group showed significantly lower FPG, 2 h PG, GA and HbA1C(P<0.05, P<0.01),and significantly higher FCP, 2 h CP and AUCcp (P<0.05, P<0.01), indicating that Astragali Radix can improve glucose metabolism. In terms of the diversity of gut microbiota, no significant differences were detected in the Chao1, Shannon and Simpson indexes of the two groups compared with their respective baselines. However, compared with the post-treatment control group, the observation group demonstrated significant increases in the Chao1, Shannon and Simpson indexes (P<0.05, P<0.01). The β-diversity analysis showed significant separation in gut microbiota composition before and after treatment in both groups, indicating that Astragali Radix can significantly alter the structure and improve the diversity of gut microbiota. At the phylum level, compared with the baseline, both groups showed a significant increase in the relative abundance of Bacteroidota(P<0.01). The relative abundance of the potentially harmful phylum Proteobacteria was significantly lower in the observation Group after treatment (P<0.01). Compared with the post-treatment control group, the observation group had a significantly higher relative abundance of Bacteroidota(P<0.01). No significant difference was found in Firmicutes/Bacteroidota (F/B) ratio between the two groups after treatment, and other phyla showed no significant differences. At the genus level, compared with the baseline, the observation group exhibited a significant increase in Bacteroides (P<0.01) and a significant decrease in Escherichia-Shigella (P<0.01), whereas no significant difference was seen in the control group . Compared with the control group after treatment, the observation group after treatment had a significantly higher relative abundance of Bacteroides (P<0.01). No significant differences were seen in other genera. Linear discriminant analysis (LDA) identified potential characteristics taxa: in the observation group, Bacteroidota at the phylum level and Bacteroides and Dubosiella at the genus level, in the control group, Proteobacteria at the phylum level as well as Barnesiella and Staphylococcus at the genus level. Correlation analysis based on a heatmap revealed that GLP-1 levels were positively correlated with Firmicutes, F/B ratio and Fusobacterium, and negatively correlated with Bacteroidota, Proteobacteria, Bacteroides and Escherichia-Shigella. In terms of clinical efficacy, compared with the control group, the total effective rate of the observation group was significantly higher (P<0.05). Compared with the baseline, the scores for shortness of breath, fatigue, weakness, spontaneous sweating and reluctance to speak significantly decreased in both groups (P<0.01). Compared with the control group after treatment, the score for weakness was significantly lower in the observation group (P<0.01),indicating that Astragali Radix could improve clinical symptoms and alleviate weakness symptoms. In terms of safety, compared with the baseline, alanine aminotransferase (ALT) levels significantly decreased in both groups (P<0.05,P<0.01),indicating that Astragali Radix did not induce any significant abnormalities in liver and kidney functions. ConclusionAstragali Radix demonstrates the potential to significantly improve the gut microbiota environment in patients of newly diagnosed type 2 diabetes with Qi deficiency. The therapeutic effect may contribute to glycemic control, possibly mediated by an elevation in GLP-1 level. These findings may support its further clinical investigations and potential applications.

This article systematically analyzed the historical evolution of the origin, scientific name, producing area, quality evaluation, harvesting and processing, and other aspects of Quisqualis Fructus by consulting the ancient materia medica, medical books, prescription books, local literature and combining with the modern literature and standards, summarized and explored the development rules of its medicinal properties and efficacy along with their underlying causes, in order to provide support for the development and utilization of famous classical formulas containing this herb. According to the textual research, Shijunzi was first recorded as Liuqiuzi in Nanfang Caomuzhuang of the Jin dynasty, and the name of Shijunzi was first used in Kaibao Bencao of the Song dynasty, which has been consistently used throughout subsequent dynasties, and there were also aliases such as Junziren, Sijunzi, and Dujilizi. The mainstream source of Quisqualis Fructus used in the past dynasties has been the dried mature fruits of Quisqualis indica, a plant belonging to the family Combretaceae. In modern times, its variety Q. indica var. villosa has also been recorded as the medicinal material of Quisqualis Fructus. In 2007, the Flora of China(English edition) designated Q. indica var. villosa as a synonym of Q. indica. Today, the accepted name of Shijunzi is updated to Combretum indicum. According to ancient herbal records, the producing areas of Quisqualis Fructus were Guangdong, Hong Kong, Macao, Guangxi, Hainan, Sichuan and Fujian, and then gradually expanded to Yunnan, Taiwan, Jiangxi and Guizhou. Since the Song dynasty, two major production regions have gradually emerged in Sichuan, Chongqing and Fujian. Currently, it is primarily cultivated in Chongqing, Guangxi and other areas, with Chongqing yielding the highest output. Since modern times, superior quality has been defined by large size, a purple-black surface, plump grains, and a yellowish-white kernel. According to ancient herbal records, the harvesting period of Quisqualis Fructus was the July and August of the lunar calendar, mostly used raw after shelling or with the shell intact, it underwent processing methods such as cleaning, slicing, mixing, steaming, roasting, stewing, and frying. Currently, the harvesting period is autumn, followed by sun-drying or low-heat drying, with processing methods including cleaning, stir-frying, and stewing. In ancient and modern literature, the records of the properties, functions and indications of Quisqualis Fructus are basically the same, that is, sweet in taste, warm in nature, predominantly non-toxic, belonging to the spleen and stomach meridians. It possesses effects of insecticide, decontamination and invigorating spleen for ascariasis, enterobiasis, abdominal pain due to worm accumulation and infantile malnutrition.The contraindications for use primarily include avoiding consumption by individuals without parasitic infestations, limiting use for those with spleen-stomach deficiency-cold, refraining from drinking hot tea during medication, and avoiding excessive intake. Based on the textual research, it is suggested that the dried mature fruits of Q. indica should be used as the medicinal material for the development of famous classical formulas containing Quisqualis Fructus. Processing methods may be chosen according to prescription requirements, and the raw products is recommended for medicinal use if not specified.

ObjectiveTo explore the effect of serum containing Zhenwutang on myocardial mast cell apoptosis induced by angiotensin Ⅱ (AngⅡ) and the mechanism of the correlation between apoptosis and mitochondrial autophagy. MethodsIn this experiment, AngⅡ and serum containing Zhenwutang with different concentrations were used to interfere with H9C2 cardiomyocytes for 24 h, and the survival rate of H9C2 cardiomyocytes was detected by cell counting kit-8 (CCK-8) to screen the optimal concentration for the experiment. Enzyme-linked immunosorbent assay (ELISA) was used to detect the content of B-type natriuretic peptide (BNP) in cell culture supernatant, and immunofluorescence was used to detect the cell surface area to verify the construction of the myocardial mast cell model. Subsequently, the experiment was divided into a blank group (20% blank serum), a model group (20% blank serum + 5×10-5 mol·L-1 AngⅡ), low-, medium-, and high-dose (5%, 10% and 20%) serum containing Zhenwutang groups, an autophagy inhibitor group (1×10-4 mol·L-1 3-MA), and autophagy inducer group (1×10-7 mol·L-1 rapamycin). The apoptosis level of H9C2 cells and the changes of mitochondrial membrane potential were detected by flow cytometry. The lysosomal probe (Lyso Tracker) and mitochondrial probe (Mito Tracker) co-localization was employed to detect autophagy. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect Caspase-3, Caspase-9, B-cell lymphoma 2 (Bcl-2), Bcl-2-related X protein (Bax), and cytochrome C (Cyt C) in apoptosis-related pathways and the relative mRNA expression of ubiquitin ligase (Parkin), phosphatase and tensin homolog (PTEN)-induced kinase 1 (PINK1), and p62 protein in mitochondrial autophagy-related pathways. Western blot was used to detect cleaved Caspase-3, cleaved Caspase-9, Bax, Bcl-2, and Cyt C in apoptosis-related pathways, phosphorylated ubiquitin ligase (p-Parkin), phosphorylated PTEN-induced kinase 1 (p-PINK1), p62, and Bcl-2 homology domain protein Beclin1 in mitochondrial autophagy-related pathways, and the change of microtubule-associated protein 1 light chain 3 (LC3) Ⅱ/Ⅰ ratio. ResultsCCK-8 showed that when the concentration of AngⅡ was 5×10-5 mol·L-1, the cell activity was the lowest, and there was no cytotoxicity. At this concentration, the surface area of cardiomyocytes was significantly increased (P<0.01), and the content of BNP in the supernatant of culture medium was significantly increased (P<0.05). Therefore, AngⅡ with a concentration of 5×10-5 mol·L-1 was selected for the subsequent modeling of myocardial mast cells. Compared with the blank group, the model group and the autophagy inhibitor 3-MA group had a significantly increased apoptosis rate (P<0.01) and significantly decreased mitochondrial membrane potential (P<0.01). The results of immunofluorescence co-localization showed that compared with the blank group, the model group had a significantly decreased number of red and green fluorescence spots. The results of Real-time PCR showed that compared with that in the blank group, the relative mRNA expression of Bax, Caspase-3, Caspase-9, Cyt C, and p62 in the model group was significantly up-regulated (P<0.01), while the relative mRNA expression of Bcl-2, Parkin, and PINK1 was significantly down-regulated (P<0.01). In addition, the relative protein expression of Bax, cleaved Caspase-3, cleaved Caspase-9, Cyt C, and p62 was significantly up-regulated (P<0.01). The LC3Ⅱ/Ⅰ was significantly decreased, and the relative protein expression of Bcl-2, p-Parkin, p-PINK1, and Beclin1 was significantly down-regulated (P<0.01). Compared with the model group, the serum containing Zhenwutang groups and the autophagy inducer group had significantly decreased apoptosis rate (P<0.01), and the decrease ratio of mitochondrial membrane potential is significantly lowered (P<0.01) in a dose-dependent manner. Additionally, both red and green fluorescence spots became more in these groups. In the 3-MA group, the number of red and green fluorescence spots decreased significantly. The relative mRNA expression of Bax, Caspase-3, Caspase-9, Cyt C, and p62 was significantly down-regulated (P<0.05, P<0.01), while that of Bcl-2, Parkin, and PINK1 was significantly up-regulated (P<0.01). In the serum containing Zhenwutang groups, the relative protein expression levels of Bax, cleaved Caspase-3, cleaved Caspase-9, Cyt C, and p62 were significantly down-regulated (P<0.05,P<0.01). The LC3Ⅱ/Ⅰ was significantly increased, and the relative protein expression levels of Bcl-2, p-Parkin, p-PINK1, and Beclin1 were significantly up-regulated (P<0.01). ConclusionThe serum containing Zhenwutang can reduce the apoptosis of myocardial mast cells and increase mitochondrial autophagy. This is related to the inhibition of intracellular Bax/Bcl-2/Caspase-3 apoptosis pathway and regulation of Parkin/PINK1 mitochondrial autophagy pathway.

BACKGROUND:Post and core restoration is a common choice for tooth defects,but the repair effects of various post and core materials are different. OBJECTIVE:To evaluate the stress distribution at the post and core,tooth root,and bonding agent site of post and core models made of different elastic modulus post and core materials using finite element method. METHODS:A three-dimensional root canal treated maxillary central incisor model was built using three-dimensional modeling software,which was restored with a full ceramic crown.The post and core materials in the restoration used nanoceramic resin(elastic modulus=12.8 GPa),composite resin(elastic modulus=16 GPa),hybrid ceramic(elastic modulus=34.7 GPa),glass ceramic(elastic modulus=95 GPa),titanium alloy(elastic modulus=112 GPa),and zirconia(elastic modulus=209.3 GPa).The model was fixed in cortical bone.A 100 N concentrated force of 45° from the long axis of the tooth was applied to 1/3 of the crown and tongue side of the central incisor.The stress distribution of the post and core,dentin,and tooth-root bonding agent in the model was repaired by the maximum principal stress criterion. RESULTS AND CONCLUSION:(1)When the post and core materials with higher elastic modulus was used,the post-core stress in the repair model was more concentrated.When the elastic modulus of the post and core materials(nanoceramic resin and composite resin)was close to dentin,the stress distribution of the post and core was more uniform.The stress distribution of dentin in all restoration models was similar regardless of post and core materials.When the post and core with higher elastic modulus was used,more stress concentration was shown at the post and root bonding agent in the repair model.(2)The maximum stress values at the post and core,tooth root,and the bonding agent site of post and tooth root in the nanoceramic resin model were 31.00,33.21,and 0.51 MPa,respectively.The maximum stress values at the post and core,tooth root,and the bonding agent between the post and tooth root in the composite resin model were 36.84,33.14,and 0.59 MPa,respectively.In the mixed ceramic model,the maximum stress values at the post and core,tooth root,and the bonding agent between the post and tooth root were 64.05,32.83,and 1.00 MPa,respectively.In the glass ceramic model,the maximum stress values at the post and core,tooth root,and the bonding agent between the post and tooth root were 112.30,32.69,and 1.73 MPa,respectively.In the titanium alloy model,the maximum stress values of the post and core,tooth root,and the bonding agent between the post and tooth root were 120.00,32.17,and 1.86 MPa,respectively.In the zirconia model,the maximum stress values of the post and core,tooth root,and the bonding agent between the post and tooth root were 148.80,31.85,and 2.28 MPa,respectively.(3)The higher the elastic modulus of the post and core material,the higher the maximum stress at the post and core during restoration.The elastic modulus of the post and core material had no significant effect on the maximum stress of the dental bonding agent and dentin.

Objective To provide technical support for the formulation of scientific and reasonable supervision measures for enterprises engaged in the exploitation and utilization of ores with associated radionuclides in Guangxi Province, China. Methods A radionuclide analysis was performed on solid materials generated during production processes such as zirconium-titanium ore dressing and processing in multiple enterprises in Guangxi Province. The radiation levels of effluents was measured. Measurement and analysis were performed on the environmental air radon concentration levels and environmental γ-radiation dose rates at the factory boundaries of these enterprises and the surrounding environmental protection targets. Results The air absorption dose rate of γ radiation, the concentrations of radon and its daughters, and the radiation levels of surface water and aerosols at the factory boundaries and in the surrounding environment were all at normal levels. The specific activities of nuclides 238U, 232Th, and 226Ra in the raw ore, zirconium products, rutile products, and monazite products within the factory area were relatively high. The γ radiation air absorption dose rates in the corresponding workshops were also relatively high, with the zirconium-rutile workshop being the area with the highest values. Materials such as zirconium products, rutile, and monazite all showed a certain amount of radon exhalation. Conclusion The radiation level of tailings met the criteria of monitoring exemption, and the enterprises did not generate radioactive solid waste. Attention should be paid to the personal dose of the staff in areas with high radiation dose rates.

OBJECTIVE To provide reference for optimizing or formulating unified evaluation methods for evidence and recommendation in expert consensus on off-label use of drugs. METHODS Retrieved from CNKI, Wanfang data, VIP, CBM, PubMed and Web of Science, Chinese expert consensuses on off-label use of drugs involving evaluation methods for evidence and recommendations were collected from the inception to August 1, 2024. After screening the literature and extracting relevant data, descriptive statistical analysis was conducted. RESULTS & CONCLUSIONS Among the 32 articles included, 14 articles (43.8%) used Micromedex’s Thomson grading system, only 7 articles (21.9%) considered economic factors when forming recommendations, 10 articles (31.3%) reported the conflicts of interest; only 2 articles (6.3%) involved experts in the field of evidence-based medicine methodology. There were differences in the sources of evidence, factors considered in forming recommendations, and the grading standards for evidence and recommendations among different expert consensus evidence evaluation methods. There were also differences in evidence levels and recommendation strength of the same drug off-label use in different expert consensus. It is recommended that in future consensus-building processes, greater attention should be paid to potential conflicts of interest among participants, collaboration with methodological experts should be enhanced, and efforts should be expedited to establish unified standards for evaluating evidence and recommendation methodologies.

ObjectiveTo unveil the mechanism of Jianpi Huogu prescription (JPHGP) in ameliorating the dyslipidemia of steroid-induced osteonecrosis of the femur head (SONFH) by oxylipidomics combined with transcriptomics. MethodsSixty SD rats were assigned into normal, model, low-, medium-, and high-dose (2.5, 5, 10 g·kg-1, respectively) JPHGP, and Jiangushengwan (1.53 g·kg-1) groups. Lipopolysaccharide was injected into the tail vein at a dose of 20 μg·kg-1 on days 1 and 2, and methylprednisolone sodium succinate was injected at a dose of 40 mg·kg-1 into the buttock muscle on days 3 to 5. The normal group received an equal volume of normal saline. Drug administration by gavage began 4 weeks after the last injection, and samples were taken after administration for 8 weeks. Hematoxylin-eosin staining was conducted to reveal the histopathological changes of the femoral head, and the number of adipocytes, the rate of empty bone lacunae, and the trabecular area were calculated. Micro-computed tomography was used for revealing the histological and histomorphometrical changes of the femoral head. Enzyme-linked immunosorbent assay was employed to measure the serum levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), apolipoprotein A1 (ApoA1), and apolipoprotein B (ApoB). At the same time, the femoral head was collected for oxylipidomic and transcriptomic detection. The differential metabolites and differential genes were enriched and analyzed, and the target genes regulating lipid metabolism were predicted. The predicted target proteins were further verified by molecular docking, immunohistochemistry, and Western blot. ResultsCompared with the normal group, the model group showcased thinning of the femoral head, trabecular fracture, karyopyknosis, subchondral cystic degeneration, increases in the number of adipocytes and the rate of empty bone lacunae (P<0.01), a reduction in the trabecular area (P<0.01), decreases in BMD, Tb.Th, Tb.N, and BV/TV, and increases in Tb.Sp and BS/BV (P<0.01). Compared with the model group, the JPHGP groups showed no obvious thinning of the femoral head or subchondroidal cystic degeneration. The high- and medium-dose JPHGP groups presented declines in the number of adipocytes and the rate of empty bone lacunae, an increase in the trabecular area (P<0.05, P<0.01), rises in BMD, Tb.Th, Tb.N, and BV/TV, and decreases in Tb.Sp and BS/BV (P<0.05, P<0.01). Compared with the normal group, the model group showcased raised serum levels of TG, TC, LDL, and ApoB and lowered serum levels of HDL and ApoA1 (P<0.01). Compared with the model group, the JPHGP groups had lowered serum levels of TG, TC, LDL, and ApoB (P<0.05, P<0.01) and a risen serum level of ApoA1 (P<0.05, P<0.01). Moreover, the serum level of HDL in the high-dose JPHGP group increased (P<0.01). A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head, and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation, lipids, apoptosis, and osteoclast differentiation. Molecular docking, immunohistochemistry, and Western blot results showed that compared with the normal group, the model group displayed increased content of 5-lipoxygenase (5-LO) and peroxisome proliferator-activated receptor γ (PPARγ) in the femoral head (P<0.01). Compared with the model group, medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ (P<0.05, P<0.01). ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.

A total of 19 different metabolites of disease set and drug set were screened out by oxylipidomics of the femoral head, and 119 core genes with restored expression were detected by transcriptomics. The enriched pathways were mainly concentrated in inflammation, lipids, apoptosis, and osteoclast differentiation. Molecular docking, immunohistochemistry, and Western blot results showed that compared with the normal group, the model group displayed increased content of 5-lipoxygenase (5-LO) and peroxisome proliferator-activated receptor γ (PPARγ) in the femoral head (P<0.01). Compared with the model group, medium- and high-dose JPHGP reduced the content of 5-LO and PPARγ (P<0.05, P<0.01). ConclusionJPHGP can restore the levels of oxidized lipid metabolites by regulating the 5-LO-PPARγ axis to treat SONFH in rats. Relevant studies provide experimental evidence for the efficacy mechanism of JPHGP in the treatment of SONFH.
