Abstract
Concussions sustained while playing sports are a prominent cause of mild traumatic brain injury (mTBI), which is prevalent among teenagers. The early and intermediate stages of mild traumatic brain injury (mTBI) can be characterized by inflammation, neurodegeneration, and brain tissue edema, which can lead to permanent brain damage. The present study investigated the therapeutic effects of triptolide in mTBI and brain damage recovery. After building mTBI model in male rat, triptolide administrated daily for 1 week in the treated group. On day 3 and day 7 of administration, hippocampus tissues were collected to evaluate inflammation and autophagy in the brain. The expressions of inflammatory factors interleukin (IL)-1β and tumor necrosis factor-alpha in serum were downregulated, while IL-10 expression was upregulated when compared with the mTBI group on day 3 and day 7. The expression of IL-10 on day 7 was higher than on day 3. Quantitative polymerase chain reaction (qPCR) analysis of inflammatory-related factors (i.e., Il-1β and nuclear factor-κB (Nf-κb), and western blot as well as immunofluorescence staining of autophagy-related proteins (i.e., LC3B) and aquaporin (AQP 4) showed lower expression on day 3 and day 7 in the triptolide-treated group. Moreover, NeuN immunostaining, and hematoxylin and eosin (HE) staining for hippocampus region revealed that the triptolide-treated group showed a decrease in damaged cells. Our findings emphasize the effectiveness of triptolide therapy after mild traumatic brain injury via modulating autophagy, attenuating inflammation and reduces edema by decreasing AQP 4 expression.

The Efficacy of Tripterygium Glycosides Combined with LMWH in Treatment of HSPN in Children. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:7223613. [PMID: 34721642 PMCID: PMC8553442 DOI: 10.1155/2021/7223613] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 10/12/2021] [Indexed: 11/18/2022]
Abstract
Objective This study aimed to explore the clinical efficacy and relevant mechanism of Tripterygium glycosides combined with low molecular weight heparin calcium (LMWH) in the treatment of Henoch–Schönlein purpura nephritis (HSPN) in children. Methods 64 cases of children patients with HSPN treated at Qilu Hospital (Qingdao) from January 2015 to May 2020 were selected and randomly divided into the control group and the observation group and 32 cases in each group. Conventional medical treatment was applied in the two groups, besides which the control group was given LMWH while the observation group was given Tripterygium glycosides based on the control group. The clinical efficacy and the indexes of clinical symptoms of the two groups were compared. Immune globulin level, fibrinogen content (FIB), prothrombin time (PT), platelet level (PLT), and activated partial thromboplastin time (APTT) level of the two groups were compared before and after the treatment. Results The total effective rate in the observation group was significantly higher than that of the control group, and the recurrence rate in the observation group was lower than that in the control group. After treatment, urine red blood cell count and 24 h urine protein were obviously better than those of the control group. There was no statistically significant difference in PT between the two groups of children before and after treatment. The levels of PLT and FIB in the two groups of patients after treatment were significantly lower than before treatment, and the PLT levels in the observation group were lower than those in the control group. Conclusion The combination of Tripterygium glycosides and LMWH had good clinical effects in the treatment of children with HSPN, and it could improve the clinical symptoms, the mechanism of which might be related to the increase of PT, a decrease of PLT, and the improvement of coagulation function.

Efficacy of tripterygium glycosides combined with ARB on diabetic nephropathy: a meta-analysis. Biosci Rep 2021; 40:226682. [PMID: 33057690 PMCID: PMC7670565 DOI: 10.1042/bsr20202391] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 09/28/2020] [Accepted: 10/05/2020] [Indexed: 12/14/2022] Open
Abstract
The purpose of this meta-analysis was to evaluate the beneficial and adverse effects of tripterygium glycosides (TGs) combined with angiotensin II receptor blocker (ARB) on diabetic nephropathy (DN). We searched for randomized controlled trials (RCTs) in PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Biomedical Literature Database, China Science and Technology Journal Database up to June 2017. Weighted mean difference (WMD) and standardized mean difference (SMD) were used for continuous variables and all variables were expressed by 95% confidence interval (CI). Twenty-three studies with 1810 DN patients were included in this meta-analysis. TG combined with ARB statistically significantly improved 24-h urinary total protein (24-h UTP) (SMD = −1.46; 95% CI = −1.84 to −1.09; P<0.00001), urinary albumin excretion rate (UAER) (SMD = −6.9; 95% CI = −9.65 to −4.14, P<0.00001), serum creatinine (SCr) (WMD = −7.65.14; 95% CI = −12.99 to −2.31; P=0.005) and albumin (Alb) (WMD = 5.7; 95% CI = 4.44 to 6.96; P<0.00001) more than did ARB alone. TG combined with ARB statistically significantly affected the level of serum glutamic pyruvic transaminase (SGPT) (WMD = 1.08; 95% CI = 0.04 to 2.12, P=0.04) more than did ARB alone. Compared with ARB alone, TG combined with ARB showed no significant difference in improving blood urea nitrogen (BUN) and hemoglobin A1c (HbA1c). Minor side effects from the combined treatment were observed and mainly focused on the abnormal liver function. TG combined with ARB offers a novel concept in treating DN, more high-quality RCTs are needed for better understanding and applying the combined treatment in DN.

Triptolidenol, isolated from Tripterygium wilfordii, disrupted NF-κB/COX-2 pathway by targeting ATP-binding sites of IKKβ in clear cell renal cell carcinoma. Fitoterapia 2020; 148:104779. [PMID: 33242535 DOI: 10.1016/j.fitote.2020.104779] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 11/19/2020] [Accepted: 11/21/2020] [Indexed: 10/22/2022]
Abstract
Triptolidenol (TPD) is an epoxy diterpene lactone from Tripterygium wilfordii, which has been used for chronic nephritis in China,and possessed various pharmacological properties, such as anti-inflammatory and anti-cancer activities. However, the precise molecular antitumor mechanism of TPD remains to be elucidated. In this study, we investigated the effects of TPD on human clear cell renal cell carcinoma (ccRCC) and investigated its precise anti-tumor mechanisms. It was showed that TPD significantly suppressed ccRCC cell proliferation, cell migration, and induced cell cycle arrest at S phase. Furthermore, TPD also induced apoptosis by activating the cytochrome c (cyt c)/caspase cascade signaling pathway. Moreover, using confocal immunofluorescence, a dual-luciferase reporter assay and molecular docking study, the results showed that TPD obviously reduced the expression of COX-2 by inhibiting the kinase activity of IKKβ via targeting its ATP-binding domain, and then attenuating the transactivation of NF-κB. Collectively, our study demonstrated that TPD suppressed renal cell carcinoma growth through disrupting NF-κB/COX-2 pathway by targeting ATP-binding sites of IKKβ, and provided pharmacological evidence that TPD exhibits potential use in the treatment of COX-2-mediated diseases such as ccRCC.

J Microencapsul 2019; 36:523-534. [PMID: 31190589 DOI: 10.1080/02652048.2019.1631402] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/27/2022]
Abstract
Aim: To reduce the toxic effects and achieve efficiency of Tripterygium glycosides, an oral microemulsion was designed. Method: After estimating its stability and characterisation, an animal experiment was held to evaluate its toxicity in vivo, using male and female Sprague Dawley rats. Result: The maximum loading amount of microemulsion to Tripterygium glycosides was 18.87 mg/ml. And comparing to control, the Tripterygium glycoside microemulsion can maintain a normal level of the number of sperms, the weight of testicle, testosterone (∼2.5 ng/mL) and BUN (∼5 mmol/L) to male rats. For female rats, it can prevent the ovary to be atrophy and keep FSH to be stable (>2100 ng/L). The weaker injury induced by drug-loaded microemulsion to rats also could be observed in histological sections to kidney and reproductive organs. Conclusions: Although the blank microemulsion had slight toxicity, it mitigated the toxicity of Tripterygium glycosides to kidney and reproductive system.
