ObjectiveTo investigate the mechanisms by which Huanglian Jiedutang (HLJDT) modulates microglial (MG) phenotypes through the sialic acid-binding Ig-like lectin 2 (SIGLEC2/CD22)/Src-homology-2-domain-containing protein tyrosine phosphatase-1 (SHP-1)/phosphorylated protein kinase B (p-Akt) signaling pathway, thereby promoting myelin repair and alleviating agitation-like behaviors in vascular dementia (VAD). MethodsSixty C57BL/6J mice were randomly assigned to a sham (normal) group, model group, HLJDT low-, medium-, and high-dose groups (2.5, 5, and 10 g·kg-1·d-1), and a risperidone group (2 mg·kg-1·d-1), with 10 mice per group. VAD was induced by bilateral common carotid artery stenosis (BCAS). From day 42, mice received drug interventions for 2 weeks. Agitation-like behaviors were assessed using the resident-intruder test. After behavioral testing, ventrolateral part of the ventromedial hypothalamus (VMHvl) tissues were collected. Western blot was used to measure protein levels of myelin oligodendrocyte glycoprotein (MOG), myelin basic protein (MBP), proteolipid protein (PLP), inducible nitric oxide synthase (iNOS), arginase-1 (Arg1), CD86, CD206, and CD22, SHP-1, and p-Akt. Immunofluorescence was used to evaluate myelin-associated glycoprotein (MAG) intensity and the proportion of iNOS+/ionized calcium-binding adapter molecule 1 (Iba1)+ cells. ELISA was used to detect tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-1β. ResultsCompared with the normal group, the model group exhibited markedly increased biting and aggressive behaviors and shortened attack latency (P<0.01). MOG, MBP, and PLP protein levels and MAG fluorescence intensity were significantly reduced (P<0.05, P<0.01). INOS and CD86 expression and TNF-α, IL-6, and IL-1β levels were significantly elevated (P<0.01). CD22 and SHP-1 expression increased significantly (P<0.01), whereas p-Akt expression decreased (P<0.01). Compared with the model group, the medium- and high-dose HLJDT groups and the risperidone group showed markedly reduced biting and aggression (P<0.05, P<0.01) and prolonged attack latency (P<0.01). MOG, MBP, and PLP levels and MAG fluorescence intensity were significantly increased (P<0.05, P<0.01). INOS, CD86, TNF-α, IL-6, and IL-1β levels decreased significantly (P<0.05, P<0.01). CD22 and SHP-1 expression decreased, while p-Akt expression increased significantly (P<0.05, P<0.01). ConclusionHLJDT may modulate CD22/SHP-1/p-Akt signaling in the VMHvl, promote the shift of MG toward an anti-inflammatory and phagocytic phenotype, enhance myelin repair, and improve agitation-like behaviors in VAD mice.

Retinitis pigmentosa (RP) is the most common hereditary blinding eye disease in clinical practice, with the pathogenesis remaining unclear. Patients experience progressive apoptosis of retinal photoreceptor cells, accompanied by degeneration of retinal pigment epithelium (RPE) cells. Current Western medical treatments mainly focus on gene therapy and stem cell transplantation, showing limited efficacy. In contrast, clinical observations have confirmed the therapeutic effects of traditional Chinese medicine (TCM) treatments. Establishing an RP animal model that aligns with the diagnostic features of both TCM and Western medicine could help combine the strengths of both approaches, thereby broadening the treatment options for RP. This study categorizes and summarizes the existing RP animal models in terms of classification, types, inheritance patterns, and alignment with clinical manifestations. It is found that current RP models are primarily derived from natural animal models such as RD mice and RCS rats, transgenic animal models like RPE-65 knockout mice and rhodopsin gene knockout mice, and chemically induced models such as those created by monochromatic light exposure or N-ethyl-N-nitrosourea (ENU) administration. These three categories of models focus more on detecting RP-related histopathological, molecular biological, and cellular immunological indicators, but offer limited observation of the overall characteristics of the disease and lack insight into syndrome differentiation. Although RP is a congenital genetic disease, its progression is influenced by acquired factors such as environment, constitution, emotions, and care. Current models do not fully capture the characteristics of this disease. Therefore, establishing an RP animal model based on the diagnostic features of both TCM and Western medicine will have significant implications for future experimental and clinical research.

ObjectiveTo evaluate the clinical efficacy and safety of Jingmaiyan granules (composed of Lonicerae Japonicae Flos, Sedi Herba, Paeoniae Radix Rubra, Moutan Cortex, Rhei Radix et Rhizoma Praeparata, and Glycyrrhizae Radix et Rhizoma) combined with external application of Jinhuang Ointment in treating acute-stage blood heat stasis type superficial thrombophlebitis (ST) of lower extremities, and to explore their effects on hemorheology and serum inflammatory factors. MethodsA randomized, double-blind, placebo-controlled clinical trial was conducted. A total of 124 patients with lower extremity ST were randomized into two groups(62 cases in each group). The control group received external application of Jinhuang ointment and oral placebo treatment, while the observation group received external application of Jinhuang ointment and oral Jingmaiyan granules. Both groups were treated for 2 weeks. The clinical symptom scores, therapeutic efficacy of traditional Chinese medicine (TCM) syndrome, pain visual analog scale (VAS) scores, hemorheological indices [including whole blood high-shear, medium-shear, and low-shear viscosity, as well as plasma viscosity (PV)], and inflammatory factors [C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)] were compared before and after treatment. ResultsAfter 2 weeks of treatment, the total effective rate in the observation group (98.3%, 60/62) was significantly higher than that in the control group (83.8%, 52/62), with a statistically significant difference (Z=3.512 1, P<0.05). Compared with pre-treatment scores, the scores for skin color, skin temperature, swelling, pain, and cord or nodules were significantly reduced in both groups (P<0.05), with more pronounced improvement in the observation group (P<0.05). Additionally, compared with pre-treatment levels, the whole blood viscosity (low-, medium-, and high-shear) significantly improved in both groups after treatment (P<0.05), with more marked improvement in the observation group (P<0.05). Furthermore, the plasma viscosity, CRP, IL-6, and TNF-α levels were significantly reduced in both groups after treatment (P<0.05), with more pronounced improvement observed in the observation group (P<0.05). ConclusionThe combination of external application of Jinhuang ointment and oral Jingmaiyan granules effectively improves clinical symptoms, hemorheological abnormalities, and inflammatory responses in patients with acute stage blood heat stasis type ST of lower extremities. The treatment is safe and holds clinical promotion value.
5.Rehmanniae Radix Preparata in Common Central Nervous System Diseases: A Review
Chinese Journal of Experimental Traditional Medical Formulae 2026;32(6):286-296
Central nervous system diseases refer to complex disorders that affect the structure and function of the central nervous system (brain and spinal cord). Due to their complex pathogenesis and the lack of effective therapies, the diseases have become one of the leading causes of human death and have imposed a heavy economic burden on families and society. Rehmanniae Radix Preparata, a representative traditional Chinese medicine for "nourishing essence and enriching marrow", has multi-target and multi-pathway advantages in the treatment of central nervous system diseases. It contains various active components such as catapol, verbascoside, and echinacoside and has multiple pharmacological effects including anti-depression, neuroprotection, antioxidation, anti-inflammation, and immunomodulation. In Alzheimer's disease, Rehmanniae Radix Preparata can regulate the processing of beta-amyloid precursor protein to reduce its production, and its antioxidative and neuroprotective effects can alleviate related pathological damage. In Parkinson's disease, it can protect dopaminergic neurons by regulating intracellular signal transduction pathways. In ischemic stroke, its antioxidative, anti-inflammatory, and neuroprotective effects can alleviate pathological reactions. Multiple sclerosis is an autoimmune demyelinating disease, and its pathogenesis is related to the autoimmune response attacking the myelin sheath of the central nervous system. The anti-inflammatory effect of Rehmanniae Radix Preparata can help inhibit this autoimmune response, reduce the damage of inflammation to the myelin sheath, and protect damaged neurons while promoting myelin sheath repair. In depression, Rehmanniae Radix Preparata can improve neural plasticity, and its anti-inflammatory effect can regulate neuroendocrine function and influence the metabolism of neurotransmitters. This paper explored the action mechanism of Rehmanniae Radix Preparata in central nervous system diseases and summarized the relevant basic research and research progress on its active components and traditional Chinese medicine formulas for treating central nervous system diseases, providing a theoretical basis for the development of traditional Chinese medicine products for the prevention and treatment of central nervous system diseases with Radix Rehmanniae Preparata.

[Objective] To establish a new scoring system to predict the perioperative outcomes (operation time, intraoperative blood loss, and trifecta achievement) in patients undergoing robot-assisted partial nephrectomy (RAPN) by integrating the RENAL and Mayo adhesive probability (MAP) scores. [Methods] Clinical data of 178 patients with renal cell carcinoma who underwent RAPN performed by the same surgeon in our hospital during Jan.2015 and Jan.2022 were retrospectively analyzed.The RENAL and MAP scores of all patients were calculated.Linear regression and logistic regression were used to evaluate the associations between the components of the RENAL and MAP scores (a total of 6 variables) and perioperative outcomes.The factors with significant associations were then included into logistic regression analysis to identify independent predictors for constructing an assessment system for perioperative outcomes, and the receiver operating characteristic (ROC) curve was plotted to calculate the area under the curve (AUC) to predict its efficacy. [Results] Multivariate linear regression analysis showed that tumor size (β=6.14, 95%CI: 1.93—10.34, P=0.004), exophytic rate (β=10.60, 95%CI: 3.44—17.76, P=0.004), and perinephric fat thickness (β=16.48, 95%CI: 8.52—24.45, P<0.001) were significantly associated with operation time.Tumor size (β=10.55 95%CI: 5.60—15.49, P<0.001) was associated with both intraoperative blood loss and trifecta achievement (OR=1.73, 95%CI: 1.26—2.36, P=0.001). Multivariate logistic regression analysis of these 3 factors identified tumor size (OR=9.07, 95% CI: 1.18—69.45, P=0.03) and perinephric fat thickness (OR=2.28, 95%CI: 1.86—6.04, P=0.01) as independent predictors of perioperative outcomes.Based on these findings, the tumor size and perinephric fat thickness (RP) scoring was constructed, which demonstrated better predictive ability than RENAL score or MAP score alone (RP vs.RENAL vs.MAP: 0.766 vs.0.548 vs.0.684). [Conclusion] The RP score includes fewer variables than the RENAL and MAP scores but outperforms them.

Xiaoji Yinzi is one of the classic prescriptions for treating urinary diseases, originated from the Yan's Prescriptions to Aid the Living (Yan Shi Ji Sheng Fang) written by YAN Yonghe in the Song dynasty. Xiaoji Yinzi is composed of Rehmanniae Radix, Cirsii Herba, Talcum, Akebiae Caulis, Typhae Pollen, Nelumbinis Rhizomatis Nodus, Lophatheri Herba, Angelicae Sinensis Radix, Gardeniae Fructus, and Glycyrrhizae Radix et Rhizoma and has the effects of cooling blood and stopping bleeding, draining water and relieving stranguria. The medical experts of later generations have inherited the original prescription recorded in the Yan's Prescriptions to Aid the Living, while dispute has emerged during the inheritance of this prescription. In this study, the method of bibliometrics was employed to review and analyze the ancient documents and modern clinical studies involving Xiaoji Yinzi. The results showed that Xiaoji Yinzi has two dosage forms: powder and decoction. According to the measurement system in the Song Dynasty, the modern doses of hers in Xiaoji Yinzi were transformed. In the prepration of Xiaoji Yinzi powder, 149.2 g of Rehmanniae Radix and 20.65 g each of Cirsii Herba, Talcum, Akebiae Caulis, stir-fried Typhae Pollen, Nelumbinis Rhizomatis Nodus, Lophatheri Herba, wine-processed Angelicae Sinensis Radix, stir-fried Gardeniae Fructus, and stir-fried Glycyrrhizae Radix et Rhizoma are grounded into fine powder with the particle size of 4-10 meshes and a decocted with 450 mL water to reach a volume of 240 mL. After removal of the residue, the decoction was taken warm before meals, 3 times a day (i.e., 7.77 g Rehmanniae Radix and 0.97 g each of the other herbs each time). In the preparation of Xiaoji Yinzi decoction, 20.65 g each of the above 10 herbs are used, with stir-fried Typhae Pollen, wine-processed Angelica Sinensis Radix, stir-fired Gardeniae Fructus, stir-fired Glycyrrhizae Radix et Rhizoma, and raw materials of other herbs. Xiaoji Yinzi is specialized in treating hematuresis and blood stranguria due to heat accumulation in lower energizer, which causes injury of the blood collaterals of gallbladder and dysfunction of Qi transformation. In modern clinical practice, Xiaoji Yinzi is specifically used for treating urinary diseases and can be expanded to treat diseases of the cardiovascular system and other systems according to pathogenesis. The comprehensive research on the key information could provide a scientific reference for the future development of Xiaoji Yinzi.

Objective To construct a glioma microfluidic chip model to simulate tumor microenvironment for evaluating the medicinal efficacy of anti-glioma traditional Chinese medicines. Methods Glioblastoma cells U251 were seeded into microfluidic chips with different culture modes, and the cell viability and tumour microenvironment within the constructed model were characterized. Fluorescence staining was used to evaluate the effects of the positive drugs temozolomide (TMZ) and docetaxel (DOC) on the cell activity and apoptosis within the model, which was applied to evaluate the medicinal efficacy of the extracts of the herb Scutellaria barbata on gliomas. Results The cells in the constructed U251 microfluidic chip model displayed high viability and were able to mimic the hypoxic microenvironment of tumor to a certain extent. The viability of the U251 cells in the microfluidic chips decreased with the increasing of the concentration of the positive drug, and the viability of the 3D cultured U251 cells was higher than that in the 2D condition (P<0.05). The intracellular mitochondrial membrane potential decreased with the increasing of the concentration of the positive drug. And the 2 mg/ml Scutellaria barbata extract killed U251 cells to a certain extent and reduced the mitochondrial membrane potential of the cells in the model. Conclusion This study successfully constructed a microfluidic chip model of glioma that could effectively simulate the tumor microenvironment and rapidly evaluate the anti-tumor medicinal efficacy, which provided a new strategy for the medicinal efficacy evaluation and active components screening of anti-glioma traditional Chinese medicines.

OBJECTIVE To study the effects of Sanchong tongluo sanjie formula on the proliferation and apoptosis of Lewis lung cancer cells. METHODS The rats were given Sanchong tongluo sanjie formula powder [0.946 g/(kg·d)], Sanchong tongluo sanjie formula decoction [2.730 g/(kg·d)], and normal saline intragastrically, and injected with Cisplatin injection (4.2 mg/kg) intra-peritoneally to prepare powder-containing serum, decoction-containing serum, positive control serum and negative control serum. Lewis lung cancer cells were divided into negative control serum group, positive control serum group, and 5%, 10%, 20% drug-containing serum groups. The cell proliferation inhibition rates at 24, 48, and 72 hours post- intervention were measured to screen the optimal intervention concentrations of powder-containing serum and decoction-containing serum. The cell invasion ability, metastasis ability and apoptotic rate were detected in the negative control serum group, positive control serum group, 20% powder-containing serum group, and 20% decoction-containing serum group. Protein expressions of vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1α (HIF-1α), prolyl hydroxylase-2 (PHD2), matrix metalloproteinase-2 (MMP-2), extracellular regulated protein kinases (ERK),c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (p38 MAPK) were detected. RESULTS The cell proliferation inhibition rates for both the 20% powder-containing serum group and the 20% decoction-containing serum group, when intervened for 48 hours, were not less than 50%. Compared with negative control serum group, the number of invasive Lewis lung cancer cells and migration distance were decreased significantly, while the apoptotic rate was increased significantly (P<0.05); the apoptotic rate in the 20% powder- containing serum group was significantly higher than 20% decoction-containing serum group (P<0.05). The protein expressions of PHD2 and p38 MAPK were increased significantly in the 20% powder-containing serum group (P<0.05), while the protein expression of HIF-1α was decreased significantly in the 20% decoction-containing serum group (P<0.05). CONCLUSIONS Sanchong tongluo sanjie formula can inhibit the proliferation, invasion and metastasis of Lewis lung cancer cells while promoting their apoptosis. The mechanism of action may be related to regulating the PHD2/HIF-1α signaling pathway. Furthermore, the powder demonstrates superior efficacy compared to the decoction, suggesting that they may possess different mechanisms of action.
