ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome). MethodsThrough a multi-center randomized controlled methodology design,confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals,such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days,and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale (CARIFS) and the incidence of complications,severe cases, and critical cases. Follow-up observation was conducted on the day of enrollment,48 hours after medication,72 hours after medication, and (6+1) d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group (90 cases) or the control group (90 cases). All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was (5.29±1.25) d,and that in the control group was (5.40±1.68) d,without a statistically significant difference. After five days of intervention,52 cases in the experimental group and 51 cases in the control group converted to negative,without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention,there were statistically significant differences between the experimental group and the control group in three dimensions, including headache,muscle soreness, and the need for extra care (P<0.05). On the (6+1) days after the intervention,the differences in both the experimental group and the control group were statistically significant in 10 dimensions, including sore throat,bad sleep,uncomfortable feeling,poor spirit and fatigue,crying more than usual,the need for extra care,symptom,function,influence on parents,and total score (P<0.05). The comparison results within the group in the dimensional scores of symptom, function, and influence on parents,as well as the CARIFS total score showed that with the delay of follow-up time,scores of both groups decreased significantly,with a statistically significant difference (P<0.01). Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention,the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up,the mean score of the experimental group was lower than that of the control group,with no statistically significant difference. In terms of the incidence of complications,severe cases, and critical cases, there were no complications,severe cases, and critical cases in the two groups,without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome) are not inferior to Oseltamivir Phosphate granules, and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children (heat accumulation in the lung and stomach syndrome).
2.From Cure to Control: Construction and Application of “Green Therapy” System for Tumors in the Elderly
Cancer Research on Prevention and Treatment 2026;53(7):509-515
Elderly patients with tumors face unique challenges due to age-related decline in organ function, multiple comorbidities, and poor tolerance to treatment, often limiting the applicability of the traditional “maximum tolerated therapy” approach in this population. This article aims to explore the “green therapy” system tailored for tumors in elderly patients. Proposed by Professor Hu Kaiwen in 2003, this system replaces “cure” with “control,” integrating modern minimally invasive techniques with holistic regulation from Traditional Chinese Medicine to form a treatment strategy that balances local and systemic approaches. This paper systematically elucidates the construction and application of this system in tumors in elderly patients, highlighting its core value of achieving long-term peaceful coexistence between patients and tumors through low-damage methods, thereby offering a new treatment option aligned with the physiological characteristics of this population.

ObjectiveTo investigate the mechanism of Tangbikang dry paste in the prevention and treatment of type 2 diabetic peripheral neuropathy (DPN) based on the glyoxalase-1 (GLO-1)/advanced glycation end products (AGE)/receptor for advanced glycation end products (RAGE) pathway. MethodsA total of 56 Sprague-Dawley rats were randomly divided, with eight assigned to the normal group. The remaining 48 rats were fed a high-fat diet combined with intraperitoneal injection of streptozotocin (STZ) to induce a type 2 diabetes mellitus (T2DM) model. Based on blood glucose levels, the rats were randomly assigned to the model group, Tanglin group (13.5 mg·kg-1), metformin group (135 mg·kg-1), and Tangbikang dry paste low-, medium-, and high-dose groups (3, 6, 12 g·kg-1). Successful modeling of DPN was confirmed by a decrease in mechanical pain threshold in the model group at week 4. Fasting blood glucose, body weight, and mechanical pain threshold were measured every 4 weeks. After 16 weeks of intervention, the pathological morphology of the sciatic nerve was observed using hematoxylin-eosin (HE) staining. The expression of RAGE, AGE, protein kinase C (PKC), and collagen (COL) in the sciatic nerve was assessed by immunohistochemistry. The mRNA expression of RAGE, PKC, Toll-like receptor (TLR), COL, and GLO-1 was detected using real-time quantitative PCR (Real-time PCR). Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CREA), urea (UREA), interleukin-6 (IL-6), and tumor necrosis factor (TNF)-α were measured by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the normal group, the model group showed significantly increased fasting blood glucose (P<0.01), decreased body weight and mechanical pain threshold (P<0.01), and elevated serum AST, ALT, CREA, UREA, IL-6, and TNF-α levels (P<0.01). The expression of RAGE, AGE, and PKC in the sciatic nerve was significantly increased (P<0.01), while COL expression was decreased (P<0.01). The mRNA expression of TLR, RAGE, and PKC was upregulated (P<0.01), whereas COL and GLO-1 mRNA levels were downregulated (P<0.01). Histological examination showed irregular nerve morphology, axonal alterations, and myelin degeneration. Compared with the model group, fasting blood glucose levels in the Tangbikang dry paste high-dose group at all time points and in the medium-dose group at weeks 4 and 16 were significantly reduced (P<0.05, P<0.01). No significant changes in body weight were observed across all Tangbikang dose groups. The mechanical pain threshold was elevated at different time points after administration in all Tangbikang groups (P<0.05, P<0.01). Serum IL-6 and TNF-α levels were decreased in all dose groups (P<0.05, P<0.01). The expression of RAGE, AGE, and PKC in the sciatic nerve was reduced (P<0.01), while COL expression was increased (P<0.01). The mRNA expression of TLR, RAGE, and PKC was downregulated (P<0.01), whereas GLO-1 mRNA expression was upregulated (P<0.05, P<0.01). Additionally, COL mRNA expression was significantly increased in the low- and high-dose groups (P<0.01). Pathological changes in the sciatic nerve were milder in all Tangbikang groups compared to the model group. ConclusionTangbikang dry paste significantly improves DPN, and its mechanism may be associated with the regulation of the GLO-1/AGE/RAGE signaling pathway.

ObjectiveTo investigate the efficacy and underlying mechanisms of Gynostemma pentaphyllum alcohol extract in improving glucose and lipid metabolism disorders in db/db mice through transcriptomics and gut microbiota analysis. MethodsEighteen db/db mice were randomly assigned to the model(DM) group, metformin(MET) group, and G. pentaphyllum alcohol extract(GP) group, with six mice in each group, based on stratification of fasting blood glucose and body weight. An additional six db/m mice were selected as the normal control(NC) group. Mice in the NC and DM groups were administered deionized water (10 mL·kg-1) daily. The MET group received metformin (0.195 g·kg-1) by gavage. The GP group was treated with G. pentaphyllum alcohol extract (3.9 g·kg-1) by gavage for six weeks. Fasting blood glucose was measured every two weeks. After six weeks of intervention, serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CREA), and blood urea nitrogen (BUN) were assessed. Enzyme-linked immunosorbent assay (ELISA) was used to measure insulin (FINS), adiponectin (ADP), and tumor necrosis factor-α (TNF-α). Hematoxylin-eosin (HE) staining was used to observe liver histomorphology, periodic acid-Schiff (PAS) staining was employed to assess hepatic glycogen synthesis, and Oil Red O staining was used to detect hepatic lipid deposition. Liver transcriptomic data were used to identify differentially expressed genes in the liver and conduct enrichment analysis. Real-time PCR was employed to verify the expression levels of adiponectin gene (Adipoq), peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor α (PPARα), glucokinase (GCK), forkhead box (Fox)O1, FoxO3, phosphoenolpyruvate carboxykinase (PEPCK), and glucose-6-phosphatase (G6PC). Metagenomic sequencing was conducted to analyze changes in gut microbiota composition. ResultsCompared with the NC group, the DM group exhibited significantly elevated fasting blood glucose (P<0.01), serum AST, ALT, TC, TG, LDL-C, and HDL-C (P<0.01). FINS, homeostatic model assessment for insulin resistance (HOMA-IR), and the inflammatory cytokine TNF-α were significantly increased (P<0.01), while ADP was significantly decreased (P<0.05). Histological analysis confirmed severe hepatic steatosis and excessive lipid accumulation in the DM group, along with markedly reduced glycogen synthesis. Compared with the DM group, the GP group showed significantly decreased fasting blood glucose (P<0.01), reduced serum TC, LDL-C, and HDL-C levels (P<0.05), significantly decreased serum TG and AST levels (P<0.01), significantly reduced FINS, HOMA-IR, and TNF-α levels (P<0.01), and significantly increased ADP (P<0.01). Hepatic steatosis and lipid deposition were significantly alleviated, while glycogen synthesis was markedly enhanced. Transcriptomic differential and enrichment analyses suggested that the mechanisms by which G. pentaphyllum alcohol extract improved hepatic glucose and lipid metabolism in db/db mice may involve regulation of the AMPK and FoxO signaling pathways. Real-time PCR results confirmed that expression of PGC-1α, PEPCK, G6PC, FoxO1, and FoxO3 was significantly downregulated following treatment with G. pentaphyllum alcohol extract (P<0.05, P<0.01), whereas mRNA expression of Adipoq, PPARα, GCK, and AMPK was significantly upregulated (P<0.05, P<0.01). Metagenomic analysis showed that the relative abundance of Lactobacillus, Alistipes, and Akkermansia species was higher in the GP group than in the DM group. ConclusionG. pentaphyllum alcohol extract may improve glucose and lipid metabolism disorders in db/db mice by regulating the hepatic AMPK/PPARα pathway to suppress lipid deposition and alleviate hepatic steatosis, by inhibiting gluconeogenesis through the AMPK/PGC-1α and FoxO pathways to lower fasting blood glucose, and by increasing the abundance of beneficial gut bacteria such as Lactobacillus, Alistipes, and Akkermansia to restore gut microbiota balance.

ObjectiveTo evaluate the therapeutic effects of modified Buwangsan on cognitive dysfunction in the rat model of type 2 diabetes mellitus with mild cognitive impairment (T2DM-MCI) and explore the underlying mechanism. MethodsThirty-six 5-week-old SPF-grade SD rats were randomly assigned into 6 groups: Normal (Con, fed with a normal diet), model (DM, fed with a high-sugar and high-fat diet), low-dose modified Buwangsan (L-BWS, 1.86 g·kg-1), medium-dose modified Buwangsan (M-BWS, 3.72 g·kg-1), high-dose modified Buwangsan (H-BWS,7.44 g·kg-1), and huperzine A (SSJJ, 0.018 mg·kg-1). The rats were treated by gavage once a day for 12 weeks. The body weight and blood glucose level were monitored dynamically. Morris water maze was employed to test the cognitive function of rats. Hematoxylin-eosin and Nissl staining were employed to observe the pathological changes of the hippocampus. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the serum and hippocampus were assessed by enzyme-linked immunosorbent assay. Western blotting was employed to determine the expression levels of key autophagy-related proteins including microtubule-associated protein 1 light chain 3 (LC3), type Ⅲ phosphatidylinositol 3-kinase complex regulatory subunit (Beclin1), and phosphorylated UNC-51-like kinase (p-ULK) 1/2 in the hippocampus. Immunofluorescence staining was employed to observe the regulation of p-PI3K/PI3K, p-mTOR/mTOR, and p-Akt/Akt ratios. ResultsCompared with the DM group, the L-BWS, M-BWS, H-BWS, and SSJJ groups showed increases in body weight at the end of the experiment (P<0.05), and the M-BWS, H-BWS and SSJJ groups showed declines in fasting blood glucose level (P<0.05). In the water maze test, compared with the DM group, the M-BWS, H-BWS, and SSJJ groups presented shortened escape latency (P<0.001). The L-BWS, M-BWS, H-BWS, and SSJJ group showcased regularly arranged cells in the hippocampus and cortex, markedly increased number of neurons, and significantly recovered Nissl bodies. Compared with the DM group, the L-BWS, M-BWS, H-BWS, and SSJJ groups had reductions in the levels of IL-1β and IL-6 in the serum and hippocampus (P<0.05), increases in the LC3-II/LC3-I ratio and expression level of beclin1 in the hippocampus (P<0.05) and the p-ULK level (P<0.05). The p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR ratios in the hippocampus decreased in the M-BWS, H-BWS, and SSJJ groups (P<0.01). ConclusionModified Buwangsan significantly ameliorates cognitive dysfunction and neurological damage in the rat model of T2DM through multiple mechanisms. It regulates metabolic disorders, lowers the blood glucose level, improves lipid metabolism, and alleviates oxidative stress. It promotes the protection and repair of neurons by inhibiting inflammatory responses and activating the autophagy pathway in the hippocampus. At the same time, modified Buwangsan relieves autophagy inhibition by regulating the PI3K/Akt/mTOR signaling pathway to alleviate the brain tissue injury.

Acupuncture is an ancient treatment method used in traditional Chinese medicine and has been popularized worldwide. Over the past decade, there has been an increase in the amount of acupuncture research, mostly comprised of randomized controlled trials (RCTs) that aimed to answer the question on the efficacy of acupuncture. However, poor methodology and low replicability in these acupuncture RCTs have resulted in uncertainty about the efficacy of acupuncture. In this review, current advancements and challenges in acupuncture RCTs, regarding the methodological aspects of randomization, blinding, sham acupuncture and quality of reporting, were discussed. While there have been advancements in various aspects, current acupuncture RCTs still face pressing issues such as inadequate randomization and blinding, unviable sham acupuncture controls, and poor reporting quality. Given these limitations, this review seeks to identify the methodological problems that are responsible for these problems and to suggest solutions that could help to overcome them so as to improve the quality of future studies evaluating the efficacy of acupuncture.

Objective:
To evaluate the therapeutic potential and underlying mechanisms of action of propolis in db/db mice.
Methods:
The chemical composition of propolis was analyzed using UHPLC-MS/MS. Thirty mice, including six wt/wt and 24 db/db mice, were randomly assigned to four groups (n = 6 per group): control, model, metformin (250 mg/kg), low dose propolis (100 mg/kg), and high dose propolis (HDP; 400 mg/kg). Treatments were administered orally for four weeks. Body weight and FBG levels were recorded weekly, and an oral glucose tolerance test was conducted on the 25th day. Serum levels of FIN, GSP, connecting peptide, AST, ALT, HDL, LDL, TG, and TC were quantified using ELISA. Liver histopathology was assessed using H&E and PAS staining. Western blotting was performed to examine the expression levels of NF-κB, phosphorylated NF-κB, IκBα, pIκBα, and AKT in liver tissues.
Results:
The top 10 metabolites of propolis were identified in positive and negative ion modes. The HDP group exhibited a significant reduction in FBG levels, body weight, connecting peptide levels, homeostatic model assessment of β-cell function scores, and homeostasis model assessment of insulin resistance scores (all P < .05). GSP levels were significantly reduced in both treatment groups (all P < .001). The HDP group also exhibited a reduction in TC and LDL levels (both P < .05), whereas HDL levels increased in both treatment groups (all P < .05). Liver weight, AST levels, and ALT levels were reduced in both treatment groups (all P < .05). Histological analysis revealed improved liver morphology. Protein analysis demonstrated downregulation of phosphorylated NF-κB and phosphorylated IκB, alongside upregulation of AKT.
Conclusion
Propolis exhibited significant antihyperglycemic effects in db/db mice, potentially by modulating the AKT and NF-κB signaling pathways, highlighting its potential as a therapeutic agent for diabetes management.
