Method: 94 patients with NAFLD were randomly divided into two groups: 48 cases of patients received oral sea buckthorn 1.5 g (3 times a day) for three months as the treated group, and 46 cases received only the vehicle for three months as the control group. Serum lipids, transaminase and serum liver fibrosis indices were assessed at baseline and after SBT treatment. All patients underwent liver CT and Fibroscan examination at baseline and after treatment. Results: SBT treatment resulted in a significant decrease in the serum levels of alanine aminotransferase (ALT), LDL-C, hyaluronic acid and collagen type IV. The liver stiffness measurement (LSM) of the treated patients was significantly lower than that in the control or baseline. The CT liver/spleen ratio of the treated patients was also significantly increased. Conclusion: The results of our study demonstrated the beneficial effects of SBT on serum lipids, transaminase, and liver/spleen ratio and liver stiffness in patients with NAFLD, which may be further developed as a promising therapy for the treatment of NAFLD.展开更多

Method: The rats (SPF level) were randomly divided into high-dose (20 mL/kg BW), middle-dose (10 mL/kg BW), low-dose (5 mL/kg BW) groups and negative control group (20 mL/kg BW of purified water) with 30 rats in each group. Each group was orally given mulberry sea-buckthorn beverage concentrate for 3 months and recovered by stop feeding samples for 2 weeks for a recovery observation. The rats’ general condition, the organ coefficient, the indexes of hematology and blood biochemistry and the histological changes of the main organs were determined. Result: The appearance and behavior of activity in rats showed no anomalies in all these groups and all the rats put on weight during this period. Comparing to the negative control group, no obvious differences were observed in the weekly weight and organ coefficient of each dose group. After 3 months of administration, HGB in both mulberry sea-buckthorn beverage concentrate low-dose group and high-dose group were increased. No significant differences were observed in the indexes of hematology after 2 weeks of recovery. CREA in low-dose, middle-dose and high-dose groups were significantly increased after 3 months of administration and it remained in the high level in middle-dose and high-dose group even after 2 weeks of recovery. No drug-related lesions were observed in the histological changes of major organs. Conclusion: The results show that long term use of mulberry concentrated sea-buckthorn beverage can lead to increased CREA, which suggested kidney toxicity. Although no obvious pathological change was found in kidney, we should pay attention to chronic kidney damage in the further research.展开更多

The primary ...Skin diseases such as psoriasis, atopic dermatitis, burns, and other barrier insults pose ongoing therapeutic challenges, often requiring treatments that address both inflammation and skin barrier repair. The primary aim of this review is to provide a comprehensive overview of the potential benefits of sea buckthorn oil, derived from Hippophae rhamnoides, as a treatment for various skin diseases, detailing its anti-inflammatory properties, reporting benefits across several skin conditions, and highlighting challenges in formulation as well as preservation of the oil’s nutritional benefits. Drawing from a wide array of existing literature, this review investigates sea buckthorn oil’s rich composition of omega fatty acids, vitamins, and antioxidants, which may contribute to its therapeutic effects by modulating inflammatory pathways and enhancing skin barrier function. Clinical trials and patient case studies indicate that sea buckthorn oil shows promise in reducing erythema, inflammation, and improving skin sensitivity. However, challenges such as formulation stability, sourcing of quality oil, and variability in response to treatment across conditions need to be addressed. Future research should focus on optimizing formulations and conducting large-scale clinical trials to validate the therapeutic efficacy of sea buckthorn oil in the management of skin diseases. Additionally, further exploration of the regulatory mechanisms underlying its ability to modulate inflammation and repair the skin barrier is needed to fully elucidate its clinical potential. Sea buckthorn oil offers a novel and promising adjunctive treatment for psoriasis, atopic dermatitis, and wound-healing with significant potential to enhance therapeutic options for additional skin diseases.展开更多

文摘Sea buckthorn market floated uncertainly within a narrow range. The market situation provided upward pressure on prices, and producer and consumer interest were poor, coupled with weak prices in the regional markets. The objectives of the study are: 1) to estimate the relationship between wild Sea buckthorn (SB) price and Supply, Demand, while some other factors of crude oil price and exchange rate by using simultaneous Supply-Demand and Price system equation and Vector Error Correction Method (VECM);2) to forecast the short-term and long-term SB price;3) to compare and evaluate the price forecasting models. Firstly, the data was analyzed by Ferris and Engle-Granger’s procedure;secondly, both price forecasting methodologies were tested by Pindyck-Rubinfeld and Makridakis’s procedure. The result shows that the VECM model is more efficient using yearly data;a short-term price forecast decreases, and a long-term price forecast is predicted to increase the Mongolian Sea buckthorn market.
文摘Objective: This study is designed to observe the chronic toxicity after the administration of mulberry sea-buckthorn beverage concentrate for 3 months on rats and to predict the possible adverse effect and the potential toxicity target organs. Method: The rats (SPF level) were randomly divided into high-dose (20 mL/kg BW), middle-dose (10 mL/kg BW), low-dose (5 mL/kg BW) groups and negative control group (20 mL/kg BW of purified water) with 30 rats in each group. Each group was orally given mulberry sea-buckthorn beverage concentrate for 3 months and recovered by stop feeding samples for 2 weeks for a recovery observation. The rats’ general condition, the organ coefficient, the indexes of hematology and blood biochemistry and the histological changes of the main organs were determined. Result: The appearance and behavior of activity in rats showed no anomalies in all these groups and all the rats put on weight during this period. Comparing to the negative control group, no obvious differences were observed in the weekly weight and organ coefficient of each dose group. After 3 months of administration, HGB in both mulberry sea-buckthorn beverage concentrate low-dose group and high-dose group were increased. No significant differences were observed in the indexes of hematology after 2 weeks of recovery. CREA in low-dose, middle-dose and high-dose groups were significantly increased after 3 months of administration and it remained in the high level in middle-dose and high-dose group even after 2 weeks of recovery. No drug-related lesions were observed in the histological changes of major organs. Conclusion: The results show that long term use of mulberry concentrated sea-buckthorn beverage can lead to increased CREA, which suggested kidney toxicity. Although no obvious pathological change was found in kidney, we should pay attention to chronic kidney damage in the further research.
文摘Skin diseases such as psoriasis, atopic dermatitis, burns, and other barrier insults pose ongoing therapeutic challenges, often requiring treatments that address both inflammation and skin barrier repair. The primary aim of this review is to provide a comprehensive overview of the potential benefits of sea buckthorn oil, derived from Hippophae rhamnoides, as a treatment for various skin diseases, detailing its anti-inflammatory properties, reporting benefits across several skin conditions, and highlighting challenges in formulation as well as preservation of the oil’s nutritional benefits. Drawing from a wide array of existing literature, this review investigates sea buckthorn oil’s rich composition of omega fatty acids, vitamins, and antioxidants, which may contribute to its therapeutic effects by modulating inflammatory pathways and enhancing skin barrier function. Clinical trials and patient case studies indicate that sea buckthorn oil shows promise in reducing erythema, inflammation, and improving skin sensitivity. However, challenges such as formulation stability, sourcing of quality oil, and variability in response to treatment across conditions need to be addressed. Future research should focus on optimizing formulations and conducting large-scale clinical trials to validate the therapeutic efficacy of sea buckthorn oil in the management of skin diseases. Additionally, further exploration of the regulatory mechanisms underlying its ability to modulate inflammation and repair the skin barrier is needed to fully elucidate its clinical potential. Sea buckthorn oil offers a novel and promising adjunctive treatment for psoriasis, atopic dermatitis, and wound-healing with significant potential to enhance therapeutic options for additional skin diseases.
