Gynura root induces hepatic veno-occlusive disease:A case report and review of the literature

Gynura root has been used extensively in Chinese folk medicine and plays a role in promoting microcirculation and relieving pain.However,its hepatic toxicity should not be neglected.Recently,we admitted a 62-year old female who developed hepatic veno-occlusive disease(HVOD)after ingestion of Gynura root.Only a few articles on HVOD induced by Gynura root have been reported in the literature.It is suspected that pyrrolizidine alkaloids in Gynura root might be responsible for HVOD.In this paper,we report a case of HVOD and review the literature.

Hypoglycemic and anti-hyperglycemic study of Gynura procumbens leaf extracts

Objective:To study the antidiabetic activity of Gynura procumbens(G.procumbens)used in the traditional management of diabetes in Southern Asia.Methods:G.procumbens leaves were extracted sequentially with graded percentage of ethanol in water(95%,75%,50%,25%and 0%),and the extracts were tested for antidiabetic activity using acute(7 h),subcutaneous glucose tolerance test and sub-chronic(14 d)test in non-diabetic and streptozotocin-induced diabetic rats.The extracts were further subjected to phytochemical studies.Results:In acute dose(1 g/kg),the extracts significantly lowered fasting blood glucose(FBG)in streptozotocin-induced diabetic rats(P<0.05).However,the FBG-lowering effect of the 25%extract compared to the other extracts,was rapid(47%after 2 h)and the highest:53%,53%and 60%in the 3rd,5th,and 7th h,respectively(P<0.05),comparable only to the effect of metformin.Furthermore,the extracts suppressed peak FBG in subcutaneous glucose tolerance test,but only the 0%and 25%extracts,and metformin sustained the decrease until the 90th min(P<0.05).Moreover,in the 14 days study,the 25%extract exerted the highest FBG-lowering effect,namely 49.38%and 65.43%on days 7 and 14,respectively(P<0.05),similar to the effect of metformin(46.26%and 65.42%).Total flavanoid and phenolic contents in the extracts were found to decrease with increase in polarity of extraction solvents.The composition of reference compounds(chlorogenic acid,rutin,astragalin and kaempferol-3-O-nrtinoside)followed a similar trend.Conclusions:G.procumbens contains antidiabetic principles,most extracted in 25%ethanol.Interaction among active components appears to determine the antidiabetic efficacy,achieved likely by a metformin-like mechanism.

[Objectives]To study the antioxidant activity of different solvent extracts of Gynura segetum in vitro,so as to provide experimental basis for further study and utilization of medicinal resources of G.segetum.[Methods]The antioxidant activity of different solvent extracts of G.segetum was determined by UV-vis spectrophotometer using DPPH free radical scavenging method and ABTS^+free radical scavenging method.[Results]The scavenging rates of DPPH and ABTS^+by acetone extract were high,reaching 98.9%and 98.3%,respectively;the scavenging rate of DPPH and ABTS^+by water extract was the lowest,and the scavenging rates were 76.7%and 77.5%,respectively.The order of ABTS^+radical scavenging rate of samples extracted with different extractants was as follows:S 5(acetone extract)>S 1(ethyl acetate extract)>S 6(ethanol extract)>S 4(n-butanol extract)>S 3(methanol extract)>S 2(distilled water extract);the order of DPPH radical scavenging rate of samples extracted with different extractants was as follows:S 5(acetone extract)>S 1(ethyl acetate extract)>S 4(n-butanol extract)>S 6(ethanol extract)>S 3(methanol extract)>S 2(distilled water extract).[Conclusions]The extracts of acetone,ethyl acetate,n-butanol,anhydrous ethanol,methanol and distilled water from the roots of G.segetum had obvious scavenging effects on DPPH and ABTS^+,all had antioxidant components,and acetone had the highest antioxidant effect as an extractant.

Effect of combination of Gynura procumbens aqueous extract and Trigona spp. honey on fertility and libido of streptozotocin-induced hyperglycaemic male rats

Objective: To study the effects of co-administration of Gynura procumbens (GP) and kelulut honey (KH) on male fertility and libido in diabetes-induced rats. Methods: A total 42 males Sprague Dawley rats aged 8 weeks were randomly and equally divided into six different groups. All groups except a normal control group were induced with 50 mg/kg of streptozotocin (STZ) intravenously to induce diabetes. A positive control group was treated with an antidiabetic drug, metformin (500 mg/kg) whereas a negative control group remained untreated throughout the experiment. Meanwhile, another three treatments on diabetic rat groups were performed and categorised as Group 1 (450 mg/kg GP+ 300 mg/kg KH), Group 2 (450 mg/kg GP + 600 mg/kg KH) and Group 3 (450 mg/kg GP+ 1200 mg/kg KH). Treatments were given for seven consecutive days through oral gavage and all rats were euthanized on day 8th for fasting blood glucose analysis, sperm quality, spermatogenesis, sexual behaviour and implantation sites analysis. Results: Fasting blood glucose levels were significantly reduced after treatment of GP and KH, compared to negative and positive controls. The treated groups showed significant increment in sperm quality compared to all control groups. Testes histology illustrated significant damages on leydig and sertoli cells for both negative and positive controls. On the contrary, co-administration of GP and KH displayed regeneration of leydig and sertoli cells in the testes. Additionally, the number of implantation sites significantly increased in females copulated with treated groups, compared to controls. Besides, the libido analysis displayed improvement of libido in treated groups, compared to all controls. Throughout the study, insignificant variances were recorded between the treated groups, indicating that treatment in Group 1 was sufficient to trigger significant improvement on fasting blood glucose level, fertility, and libido in diabetic male rats. Conclusions: Co-administration of GP and KH has great potential to serve as a pro-fertility agent amongst diabetic patients.

Expression of MMP-9 in hepatic sinusoidal obstruction syndrome induced by Gynura segetum

Background and objective： Hepatic sinusoidal obstruction syndrome （HSOS） is characterized by painful hepatomegaly, ascites, increased body weight, and jaundice. Gynura segetum （Compositae）, a plant widely used in Chinese traditional medicine, often leads to the development of HSOS. However, the mechanism is unclear. The aim was to study the role of matrix metalloproteinase-9 （MMP-9） in the onset of HSOS induced by Gynura segetum. Methods： Twenty-five male Sprague-Dawley rats were randomly divided into two groups. Twenty were exposed to 600 mg/kg daily Gynura segetum extract solution for three weeks; five control rats were exposed to tap water alone. Liver sections were evaluated by light microscopy with a modified scoring system. Routine transmission electron microscopy （TEM） methods were used to evaluate the ultrastructual features of fixed liver tissue, and blood samples were collected to determine liver enzyme concentrations. MMP-9 expression was assessed by both immunohisto- chemical staining and enzyme-linked immunosorbent assay （ELISA） methods. Results： A stable and reproducible rat model of HSOS was achieved by long-term exposure to Gynura segetum extract. The treated rats presented clinical symptoms and the histopathological manifestation of HSOS, including abnormal liver enzyme concentrations （alanine aminotransferase （ALT）： （84.8＋13.62） vs. （167.0±72.63） U/L, P〈0.05; aspartate aminotransferase （AST）： （27.6±6.31） vs. （232.8±108.58） U/L, P〈0.05）. Hematoxylin and eosin （H＆E） staining and TEM together revealed deposition of red blood cells, the damage and destruction of hepatic sinusoidal endothelial cells, collapse of hepatic sinusoids, hem- orrhage of subendothelial cells, atrophy and destruction of hepatocytes, etc. Compared with controls, the expression of MMP-9 in the blood sample, the lung and liver tissues of HSOS rats was increased. Conclusions： MMP-9 may have an important role in early patholoclical chanqes of HSOS, and thus the onset of the disease.

Clinical characteristics and outcomes of patients with hepatic veno-occlusive disease induced by Gynura segetum: A retrospective study

Objective: Hepatic veno-occlusive disease(HVOD) has attracted increasing attention in recent years due to its relationship with ingestion of Gynura segetum. The mortality of severe HVOD remains high due to the lack of specific therapies. The aim of the study was to delineate the clinical characteristics and outcomes and explore the potential prognostic factors of HVOD.Methods: This was a single-center retrospective study. Eighty-nine HVOD patients were screened from the First Affiliated Hospital of Zhejiang University with an ingestion history of G. segetum before developing symptoms from January 2009 to May 2018. The enrolled patients were divided into the survivor and death groups according to the clinical follow-up that ended on September 1, 2019. The demographic variables and clinical data of the patients were recorded. A binary logistic regression analysis and receiver operating characteristic curve were conducted to identify the prognostic factors and assess the prognostic value for predicting death, and a survival analysis was performed to evaluate the clinical outcomes.Results: Sixty-four patients were eligible for further analysis. Most patients showed abdominal distension and were positive for migrating dullness in the abdomen(P = 0.740 and P = 0.732, respectively). The patients who died had higher levels of model for end-stage liver disease score, and higher prothrombin time than those who survived(both P < 0.001). All HVOD patients in both the survival and death groups showed ascites with abnormal imaging presentations of the liver parenchyma and hepatic blood vessels.Unexpectedly, we found that hydrothorax was detected in 21(65.63%) patients in the death group and 19(59.38%) patients in the survivor group during hospitalization, which was rarely mentioned in previous studies. Furthermore, international normalized ratio(INR) and creatinine are found to be potential independent prognostic factors for predicting death. Six severe patients achieved clinical improvements and survived after liver transplantation.Conclusion: HVOD can be induced by the ingestion of G. segetum, and INR combined with creatinine has prognostic value for predicting death. Liver transplantation may be an effective treatment option for severe HVOD patients.

Synergistic Effects of CO_2 and LED Lighting on Accumulation of Terpenes in Roots of Gynura bicolor

Objective To investigate the essential oil profile and terpenes accumulation in the roots of Gynura bicolor （Asteracese） treated by CO2 and LED lighting. Methods G. bicolor herbs were treated by CO2 at the levels of 450 （control） and 1200 （elevated） μmol/mol and LED lighting with white light, RB20 （red/blue=8/2） and RB40 （red/blue=6/4）. Headspace solid-phase micro-extraction-GC MS was employed to analyze terpenes from the essential oil of the roots. Results In all treated-roots, the major components of terpenes were （E）-β-farnesene, α-, β-caryophyllene, α-, β-, γ-elemene, and α-pinene. Increasing CO2 significantly decreased mono- and sesqui-terpenes in the roots under all light conditions, leading to the decreasing yields of the essential oils. Terpenes were at a higher level in RB20-treated roots than that in RB40-treated ones under both control and elevated CO2. Conclusion CO2 （450 μmol/mol） and 20 % blue LED lights are more conducive to the accumulation of terpenes in the roots than 1200 μmol/mol CO2 and 40% blue LED lights.

Gynura procumbens aqueous extract alleviates nonalcoholic steatohepatitis through CFLAR-JNK pathway in vivo and in vitro

Objective:The present work was to investigate the protective effects of the aqueous extract of Gynura procumbens(GPAE)against nonalcoholic steatohepatitis(NASH)in mice and NCTC-1469 cells.Methods:C57 BL/6 J mice were fed with methionine and choline-deficient(MCD)diet and administered simultaneously with GPAE(500 and 1000 mg/kg/d,respectively)by gavage for six weeks.The biomarkers of NASH in serum and liver were determined.NCTC-1469 cells were pretreated with 0.25 mmol/L palmitic acid(PA)plus 0.5 mmol/L oleic acid(OA)for 24 h or treated with adenovirus expressing short-hairpin RNA against CFLAR(Ad-sh CFLAR)for 24 h and then treated with GPAE(80 and 160μg/m L,respectively)for 24 h,and the content of cellular biomarkers of NASH was detected.Results:In mice treated with MCD,GPAE could decrease the levels of serum ALT,AST,the content of hepatic TG,TC and MDA,repress the activities and protein expression of CYP2 E1 and CYP4 A and the phosphorylation of JNK,increase the activities of HO-1,CAT and GSH-Px,up-regulate the m RNA expression of PPARα,FABP5,CPT1α,ACOX,SCD-1,mGPAT,MTTP and the protein expression of CFLAR and NRF2.In NCTC-1469 cells treated with PA and OA,GPAE could decrease the content of cellular TG and ROS,promote the uptake of 2-NBDG,up-regulate the protein expression of CFLAR and NRF2.In NCTC-1469 cells treated with Ad-sh CFLAR,GPAE up-regulated the mRNA and protein expression of CFLAR,down-regulated the phosphorylation of JNK,and increased the protein expression of NRF2 and p IRS1.Conclusion:These results indicated that the activation on CFLAR-JNK pathway might be the main antiNASH mechanism of GPAE,which on the one hand promote theβ-oxidation and efflux of fatty acids in liver,and finally reduce hepatic lipid accumulation,on the other hand increase the activities of antioxidant enzymes and inhibit the activities of ROS generation enzymes by activating NRF2,and therefore attenuates hepatic oxidative stress damage.
