Objective:To explore the effects of Yishen Tonglong Granules (YSTLG) on cell proliferation and apoptosis in a nude mouse model of androgen independent prostate cancer subcutaneous transplantation based on non classical Wnt signaling pathway.Methods:The tumor-bearing nude mouse model was established using the human prostate cancer bone metastatic cell line PC-3. After successful modeling, the mice were equally divided into six groups using the random number table method: model group, Western medicine group, Chinese materia medica low-, medium-, and high-dosage groups, and Chinese materia medica-Western medicine combination group. Corresponding drug interventions were administered to each group. Following 28 consecutive days of drug administration, the nude mice were euthanized. Tumor tissues were harvested for pathological observation via HE staining. Cell proliferation was assessed by immunohistochemistry; apoptosis was detected using TUNEL assay; the expressions of non-canonical Wnt signaling pathway-related proteins (Wnt5a, Rac1, RhoA, NFATc1) were analyzed through Western blot and immunohistochemical methods.Results:THE staining results demonstrated that YSTLG could effectively ameliorate pathological alterations in tumor tissues. Compared with the model group, the Chinese materia medica low-, medium-, and high-dosage groups, as well as the Chinese materia medica-Western medicine combination group, exhibited reduced proliferation indices ( P<0.01), elevated apoptosis indices ( P<0.01), down-regulated protein expressions of Wnt5a, Rac1, RhoA, and NFATc1 ( P<0.01), and decreased optical density values of Wnt5a, Rac1, RhoA, and NFATc1 ( P<0.01). These effects displayed a dosage-dependent trend. The Chinese materia medica-Western medicine combination group achieved the most pronounced therapeutic outcomes. Conclusions:YSTLG may exert inhibitory effects on the proliferation of androgen-independent prostate cancer cells and promote apoptosis, possibly through suppression of the non-canonical Wnt signaling pathway. Furthermore, its combination with Wnt signaling inhibitors may exhibit synergistic therapeutic effects.

The pathogenesis of urolithiasis is not yet clear， and there are obvious limitations in the prevention and treatment of urolithiasis by either Chinese or western medicine. The microscopic pathological changes of the kidney from anatomical perspective have a certain internal connection with viewpoint of “kidney storing insufficiency， and kidney deficiency as the root” in the traditional Chinese medicine （TCM） zang-fu （脏腑） theory. Accordingly， the prevention and treatment of urolithiasis by integrated traditional Chinese and western medicine based on “shen-kidney” theory has been proposed. It is believed that the prevention and treatment of urolithiasis can be divided into two stages， that is expelling stones and preventing stones. In terms of preventing stones from kideny， it is recommended to focus on the early pathological changes of the kidney； for preventing stones from shen， it is advised to prevent and treat urolithiasis from kidney deficiency. The treatment should be time-based and stage by stage. Adhering to the principle of “prevention before disease occurs， prevention is more important than treatment” aims to advance the intervention targets for the prevention and treatment of urolithiasis. Emphasizing on the simultaneous treatment of kidney disease and urolithiasis， it is critical to put focus on the development of calcium-containing crystalline nephropathy in the early stage of stone formation， as well as the fundamental pathogenesis of kidney deficiency in TCM. Shen-kidney theory aims to further promote the integration of traditional Chinese and western medicine in the prevention and treatment of urolithiasis， which may provide certain reference for solving the current dilemma of urolithiasis prevention and treatment.

OBJECTIVE: To investigate the protective effect of arctiin with anti-inflammatory bioactivity against triptolide-induced nephrotoxicity in rats and explore the underlying mechanism. METHODS: Forty SD rats were divided into 4 groups for gastric lavage of normal saline, arctiin (500 mg/kg), triptolide (500 μg/kg), or both arctiin (500 mg/kg) and triptolide (500 μg/kg). Blood samples were collected for analysis of biochemical renal parameters, and the renal tissues were harvested for determining the kidney index and for pathological evaluation with HE staining. In the RESULTS: In SD rats, arctiin significantly antagonized triptolide-induced elevation of BUN, Scr and kidney index ( CONCLUSIONS Arctiin can protect the kidney from triptolide-induced damages in rats possibly through the anti-inflammatory pathway.

OBJECTIVE: To explore the effect of the composition ratio on substitution of sulfate group in sulfated exopolysaccharide (EPS) from and how sulfate modification affects the anti-tumor activity of EPS. METHODS: We used a chlorosulfonic acid-pyridine method to modify EPS and analyzed the effect of esterification ratio on the degree of sulfate substitution using barium chloride turbidimetry. The sulfate groups binding with EPS were analyzed with infrared spectrum analysis. CCK-8 assay was used to evaluate the inhibitory effect of EPS sulfate (SEPS) on the proliferation of human colon cancer HCT 116 cells, and annexin V-FITC/PI double staining was used to assess the pro-apoptotic effect of SEPS in the cells. RESULTS: The esterifying agent and EPS at the composition ratios of 1:1 and 2:1 resulted in sulfate substitution of 0.98% (SEPS-1) and 1.18% (SEPS-2), respectively, and the substitution was improved by increasing the ratio of the esterifying agent ( < 0.05). Infrared spectrum analysis showed that the S=O stretching vibration absorption peak of -OSO appeared near 1249 cm, indicating that the sulfate group combined with EPS to form sulfate. CCK-8 assay showed that SEPS-1 produced stronger inhibitory effects on the proliferation of HCT 116 cells than EPS within the concentration range of 0.02-0.10 mg/L ( < 0.05). At the concentrations of 0.04-0.08 mg/L, SEPS-2 showed a lower anti-tumor activity than SEPS-1 ( < 0.05). SEPS-1 also showed stronger pro-apoptotic effect than EPS, and as its concentration increased, SEPS-1 dose-dependently increased the ratio of early apoptotic cells and necrotic cells; the cells treated with 0.06, 0.08 and 0.10 mg/mL SEPS-1 showed early apoptotic rates of 6.38%, 11.8% and 12.5%, and late apoptotic and necrotic rates of 5.26%, 8.04% and 6.80%, respectively. CONCLUSIONS The composition ratio of the esterifying agent has a direct impact on the degree of substitution of EPS, which can be improved by increasing the ratio of the esterifying agent. Sulfate modification of EPS can enhance its antitumor activity, which, however, is not directly related with the degree of substitution.

OBJECTIVETo investigate the protective effect of monoside against triptolide-induced liver injury and explore its molecular mechanism.

METHODSBALB/C mice treated with gastric lavage with triptolide and monoside, either alone or in combination, were examined for changes of hepatic biochemical parameters using the serological method. The growth inhibition rate of HepG2 cells treated with triptolide or monoside or both was assessed with MTT assay, and the cell morphological changes were observed using laser confocal microscopy; the expressions of the target proteins in the antioxidative stress pathway were detected using flow cytometry and Western blotting.

RESULTSIn BALB/C mice, gastric lavage of triptolide induced obvious hepatic damage. In HepG2 cells, treatment with triptolide significantly inhibited the cell growth, resulting in a cell viability as low as 72.83% at 24 h; triptolide also induced obvious cell apoptosis and cell nucleus deformation, causing an apoptosis rate of 43.1% in the cells at 24 h. Triptolide significantly reduced the expressions of Nrf2 and HO-1 proteins related with the oxidative stress pathway. Combined treatment with morroniside obviously reversed these changes, resulting in significantly decreased hepatic biochemical parameters and the liver index in BALB/C mice and in significantly lowered cell apoptosis rate, improved cell morphology, and increased Nrf2 and HO-1 protein expressions in HepG2 cells.

CONCLUSIONSMonoside protects against triptolide-induced liver injury possibly by relieving oxidative stress.

OBJECTIVETo evaluate the effect of aging on the endothelial function of the penile corpus cavernosum in rats.

METHODSThe intracavernosal pressure (ICP) was compared in response to acetylcholine (Ach, endothelium-dependent vasodilator), sodium nitroprusside (SNP, an NO donor) and A23187 (a calcium ionophore)in the young (5 months old) and aged (20 months old) rats. In addition, the activity of nitric oxide synthase (NOS)in penile cavernosal tissues was examined.

RESULTSAch-mediated ICP was significantly attenuated from the maximum of (54.8 +/- 4.2) in the young rats to (40.3 +/- 2.8) mm Hg in the aged ones (Ach = 0.1 mmol/L), P < 0.01. The ICP to SNP (0.1 mmol/L) was (58.9 +/- 4.7) mm Hg in the young rats and (51.7 +/- 5.3) mm Hg in the aged. No statistically significant difference was noted between the two groups, P > 0.05. The Ach-mediated ICP in the young rats was not significantly augmented from the maximum of (54.8 +/- 4.2) to (55.8 +/- 4.7) mm Hg in the presence of the calcium ionophore A23187 (10 micromol/L), P > 0.05. However, A23187 significantly augmented Ach-mediated ICP in the aged from the maximum of (40.3 +/- 2.8) to (56.2 +/- 4.1) mm Hg, P < 0.01. Finally the activity of nitric oxide synthase was not significantly attenuated in either the aged or the young, P > 0.05.

CONCLUSIONThe endothelial function of the penile cavernosum declines with the advance of age. And endothelial dysfunction may play some role in the mechanisms of age-related erectile dysfunction.
