RESUMO
The growth environment of medicinal plants plays an important role in the formation of their medicinal quality. However, there is a lack of combined analysis studying the close relationship between the growth environment, chemical components, and related biological activities of medicinal plants. Therefore, this study investigated the effect of different soil moisture treatments on the efficacy to eliminate dampness and relieve jaundice and the flavonoid content of Sedum sarmentosum, and explored their correlation. The flavonoid content in the decoction of S. sarmentosum growing under field conditions with soil moisture levels of 35%-40%(T1), 55%-60%(T2), 75%-80%(T3), and 95%-100%(T4) was compared. The effects of these treatments on liver function parameters, liver inflammation, and oxidative damage in mice with dampness-heat jaundice were evaluated, and the correlation between pharmacological indicators and flavonoid content was analyzed. The results showed that the total flavonoid and total phenolic acid content in the decoction of S. sarmentosum were highest in the T1 treatment, followed by the T3 treatment. The content of quercetin, kaempferol, and isorhamnetin was highest in the T2, T1, and T3 treatments, respectively. Among the different moisture treatments, the T3 group of S. sarmentosum effectively reduced the levels of serum ALT, AKP, TBIL, DBIL, TBA, as well as hepatic TNF-α and IL-6 in mice with jaundice, followed by T2 treatment, especially in reducing AST level. The T4 treatment had the poorest effect. Correlation analysis showed a significant negative correlation between AST, ALT, AKP levels in mice and the total content of quercetin and the three flavonoids. MDA showed a significant negative correlation with the total flavonoid content and kaempferol. TNF-α exhibited a significant negative correlation with the content of isorhamnetin. In conclusion, S. sarmentosum growing under field conditions with a soil moisture level of 75%-80% exhibited the best efficacy to eliminate dampness and relieve jaundice. This study provides insights for optimizing the cultivation mode of medicinal plants guided by pharmacological experiments.

To explore the effect of light intensity in cultivating environment on the hepetoprotective activity of Sedum sarmentosum, S. sarmentosum were planted under five water treatments for 60 days, namely 100% full sunlight(G1), 77% full sunlight(G2), 60% full sunlight(G3), 38% full sunlight(G4), and 16% full sunlight(G5) and CCl_4 drug-induced liver injury model in vitro was used. Cell viability, cell cycle, and cell apoptosis were individually detected by MTT, PI single staining, and Annexin-V FITC/PI double staining assays. Additionally, ALT, AST and antioxidant index in supernatant were determined by colorimetry. And the relationship among the protective effects, chemical composition and antioxidant activity were also analyzed. The results showed that S. sarmentosum aqueous extract could significantly improve the HepG2 cell viability. Among the five S. sarmentosum groups, the cell viability of G1(100% full sunlight) treatment was the highest, and the cell apoptosis was the least. Meanwhile, the level of ALT, AST, and MDA in G1 was the lowest, but it achieved the highest level of SOD and GSH. Moderate light shading(60% full light) also improved the effect of protecting liver and reducing the enzyme. It was found that cell viability was positively correlated with ferricion reducing capacity. ALT activity was positively correlated with isorhamnetin content. Taken together, different light intensity had great influence on hepatoprotective effect of S. sarmentosum, which may be related to its antioxidant capacity. From the perspective of hepetoprotective activity, S. sarmentosum should be planted under full light.

Abstract Purpose: To evaluate the healing potential of the electrospinning membranes of Poly (Lactic Acid) (PLA) associated with Sedum dendroideum extract in burn injuries in rats. Methods: Seventy-five rats were submitted to burn injury on their back skin: (C) untreated; (F) with daily topical application of S. dendroideum extract; (M) with electrospinning membranes of PLA; (MF10) with electrospinning membranes of PLA with 10% S. dendroideum extract; (MF25) with electrospinning membranes of PLA with 25% S. dendroideum extract. Tissue samples were taken after 2, 6 and 14 days of the burn injury and were subjected to histomorfometric analysis of quantification of fibroblasts, collagen fibers, blood vessels, and inflammatory infiltrate Results: The histomorphometric analysis showed an increase in the number of fibroblasts, collagen fibers and blood vessels in the burns treated with membranes of PLA, associated or not with the 10% and 25% extract. The extract of S. dendroideum promoted the increase of collagen fibers. Conclusion: The electrospinning PLA membrane, isolated or associated with the S. dendrodeum extract, favored the healing of burn injuries in this experimental model, with an increase of fibroblasts, collagen fibers, and blood vessels. S. dendroideum isolated only stimulated the collagenesis.

This paper was aimed to observe the interventional effect of Sedum sarmentosum total flavanones on hepatic fibrosis and its possible mechanism through the subcutaneous injection of CCl_4 in rats. Sixty male SD rats were randomly divided into normal control group, model group, low-dose, medium-dose, high-dose S. sarmentosum total flavanones groups(100, 200, 400 mg·kg~(-1)) and silymarin group(200 mg·kg~(-1)). The model of liver fibrosis was established by subcutaneous injection of rats with 40% CCl_4. After the modeling, the drug groups were intragastrically administered with corresponding drugs once a day for consecutively five weeks, while the normal group and the model group were given 0.9% sodium chloride solution during the same period. After the experiment, the general conditions of rats and the pathological changes of liver tissues were observed, and the contents of serum ALT, AST, HA and LN were measured. Besides, the expressions of the protein and relevant mRNA of Smad2/3, Smad4 and α-SMA in rats were detected. Compared with model group, S. sarmentosum total flavanones could significantly increase the rats' body weight, inhibit the increase of liver and spleen index in rats of liver fibrosis, reduce the levels of ALT, AST, HA and LN, and alleviate pathological changes. Meanwhile, compared with the model group, the protein expressions of Smad2/3, Smad4 and α-SMA as well as relevant mRNA expressions in S. sarmentosum total flavanones group were obviously decreased, while Smad7 expression was markedly increased. As a result, S. sarmentosum total flavanones could significantly alleviate CCl_4-induced liver fibrosis, and its anti-hepatic fibrosis mechanism may be related to intervention with Smads pathway, so as to inhibit the activation of HSC.

The present study was conducted to explore the effect of light intensity on growth, bioactivity compounds accumulation and anti-oxidative activity of Sedum sarmentosum. The growth, yield, contents of total flavonoids, total phenolic, quercetin, kaempferol and isorhamnetin, and antioxidant activities were assessed in S. sarmentosum under five light intensities, namely 100% full sunlight (G1), 77% full sunlight (G2), 60% full sunlight (G3), 38% full sunlight (G4), and 16% full sunlight (G5). The results showed that light intensity significantly affected the growth and the chemical compounds accumulation. With the decrease of light intensity, the maximum branch length and the average internode distance increased. G2 treatment greatly promoted the numbers of leaf layers and branches, and G3 treatment remarkably improved the yield. The highest total flavonoids and phenolic contents were obtained in G3 treatment. Meanwhile, the highest quercetin and isorhamnetin contents were obtained in G1 treatment. The difference of kaempferol content was not significant. In addition, based on DPPH, FTC and FRAP methods, the antioxidant activities of the aqueous extracts under G1 treatment were superior to the others. The results indicated that more than 60% full sunlight was the optimum light intensity condition to achieve high yield and quality of S. sarmentosum.

At present, there were few studies about the effects of cultivation measures on the quality and pharmacological activity of medicinal plants. To explore the hepetoprotective activity of Sedum sarmentosum aqueous extracts after different water treatments, S. sarmentosum were planted under five water treatments for 60 days, namely 15%-20% FC (field capacity, S1), 35%-40% FC (S2), 55%-60% FC (S3), 75%-80% FC(S4), and 95%-100% FC (S5) and CCl₄ drug-induced liver injury model in vitro was used. Cell viability, cell cycle, and cell apoptosis were individually detected by MTT, PI single staining, and Annexin-V FITC/PI double staining assays. Additionally, ALT, AST and antioxidant index in supernatant were determined by colorimetry. The results showed that, compared with the model group, S. sarmentosum aqueous extract could significantly improve the HepG2 cell viability. Among the five S. sarmentosum groups, the cell viability of S4 (75%-80% FC) treatment was the highest, and the cell apoptosis was the least. Meanwhile, the level of ALT, AST, and MDA in S4 was the lowest, but it achieved the highest level of SOD and GSH. Taken together, different water treatments had great influence on hepatoprotective effect of S. sarmentosum, and the soil moisture of the 75%-80% FC is beneficial to the hepetoprotective activity of S. sarmentosum.

This study investigated the value of computed tomography (CT) in the diagnosis and treatment of hepatic veno-occlusive disease (HVOD) caused by Sedum aizoon (SA). The clinical manifestations, treatment results, imaging findings, and histological findings of the liver were analyzed in 39 patients with HVOD caused by SA. Hepatomegaly, liver dysfunction, abdominal effusion, and geographic density changes on liver CT scans were found in all 39 patients. The pathological findings of histological liver examination included swelling and point-like necrosis of liver cells, significant expansion and congestion of the sinuses, endothelial swelling, and wall thickening with incomplete lumen occlusion of small liver vessels. CT geographic density changes were confirmed by histological examination of the liver in 18 patients. Sixteen patients with small amounts of ascites that started within 4 weeks of treatment recovered completely or significantly improved after symptomatic and supportive treatment. However, only 43.75% of the patients with larger amounts of ascites improved following symptomatic and supportive treatment. In conclusion, liver CT examination is a valuable, safe, and noninvasive tool for the diagnosis of HVOD caused by SA. In selected cases, liver CT examination may replace liver biopsy and histological analysis.

<p><b>OBJECTIVE</b>To explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.</p><p><b>METHODS</b>Forty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.</p><p><b>RESULTS</b>Ascites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.</p><p><b>CONCLUSION</b>SSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.</p>

Physiographic factors along with edaphic conditions play a crucial role in establishment of plant species throughout a region. Identification of the most effective factors is of high importance in sustainable management of a forest ecosystem. This study aims to investigate the relationships between understory vegetation and some environmental factors in natural forest ecosystems. This study has been carried out among the Fagetum orientalis communities of Ramsar Region, located in the north of Iran. For this purpose, 105 releves were sampled by a randomized- systematic method throughout the study area, using the Braun-Blanquet scale. Physiographic parameters such as elevation, as well as slope and orientation were measured. By identification of the herb-layer vegetation contained in each sampling, vegetation composition and cover abundance of species were separately identified. Then, the aforementioned properties of soil were entirely measured in the taken samples. Cluster analysis and detrended correspondence analysis have been applied to classify the site. Moreover, in order to determine the relation between species composition and environmental factors, canonical correspondence analysis was used. Results showed a significant relation between distribution of plant types and environmental factors. Eventually, environmental factors including slope, orientation, silt percent, pH, organic matter and soluble phosphorous were among the most effective factors in establishment of Hedera pastuchowii, Solanum kieseritzkii, Oplismenus undulatifolius, Sedum stoloniferum, Rubus hyrcanus and Saxifraga cymbalaria species

Sedum alfredii Hance has been identified as zinc (Zn) and cadmium (Cd) co-hyperaccumulator. In this paper the relationships of Zn or Cd hyperaccumulation to the generation and the role of H2O2 in Sedum alfredii H. were examined. The results show that Zn and Cd contents in the shoots of Sedum alfredii H. treated with 1000 micromol/L Zn2+ and/or 200 micromol/L Cd2+ increased linearly within 15 d. Contents of total S, glutathione (GSH) and H2O2 in shoots also increased within 15 d, and then decreased. Total S and GSH contents in shoots were higher under Cd2+ treatment than under Zn2+ treatment. However, reverse trends of H2O2 content in shoots were obtained, in which much higher H2O2 content was observed in Zn2+-treated shoots than in Cd2+-treated shoots. Similarly, the microscopic imaging of H2O2 accumulation in leaves using H2O2 probe technique showed that much higher H2O2 accumulation was observed in the Zn2+-treated leaf than in the Cd2+-treated one. These results suggest that there are different responses in the generation of H2O2 upon exposure to Zn2+ and Cd2+ for the hyperaccumulator Sedum alfredii H. And this is the first report that the generation of H2O2 may play an important role in Zn hyperaccumulation in the leaves. Our results also imply that GSH may play an important role in the detoxification of dissociated Zn/Cd and the generation of H2O2.

Radiotracer techniques were employed to characterize (65)Zn adsorption and desorption in root-cell-wall of hyperaccumulating ecotype (HE) and non-hyperaccumulating ecotype (NHE) species of Sedum alfredii Hance. The results indicated that at the end of a 30 min short time radioisotope loading period, comparable amounts of (65)Zn were accumulated in the roots of the two ecotypes Sedum alfredii, whereas 2.1-fold more (65)Zn remains in NHE root after 45-min desorption. At the end of 60 min uptake period, no difference of (65)Zn accumulation was observed in undesorbed root-cell-wall of Sedum alfredii. However, 3.0-fold more (65)Zn accumulated in desorbed root-cell-wall of NHE. Zn(2+) binding in root-cell-wall preparations of NHE was greater than that in HE under high Zn(2+) concentration. All these results suggested that root-cell-wall of the two ecotypes Sedum alfredii had the same ability to adsorb Zn(2+), whereas the desorption characteristics were different, and with most of (65)Zn binding on root of HE being available for loading into the xylem, as a result, more (65)Zn was translocated to the shoot.
