Millettia dielsiana is a traditional herb medicine to treat rheumatic arthritis and gynecological diseases. In this study, a novel polysaccharide (MDP1) with a molecular weight of 139.54 kDa was isolated from Millettia dielsiana by DEAE-52 cellulose chromatography. Its sulfated derivative (S-MDP1) was prepared by the chlorosulfonic acid-pyridine method. Structural analysis indicated that MDP1 was a pectic polysaccharide and did not exhibit a triple helical conformation. In vitro, MDP1 and S-MDP1 had protective effect on H2 O2 -induced PC12 cells death...

Matrine is a natural compound extracted from the herb Sophora flavescens Ait which is widely used in traditional Chinese medicine for treating various diseases. Recently, matrine was reported to have antitumor effects against a variety of cancers without any obvious side effects; however, the molecular mechanisms of its antiproliferative effects on cancer are unclear. Here, we report that matrine inhibits autophagy-mediated energy metabolism, which is necessary for pancreatic cancer growth. We found that matrine significantly reduces pancreatic cancer growth in vitro and in vivo by insufficiently maintaining mitochondrial metabolic function and energy level...

Triptolide, the predominant biologically active component of the Chinese herb Tripterygium wilfordii Hook f., possesses numerous pharmacological activities, including anti-inflammatory, anti-fertility, anti-neoplastic, and immunosuppressive effects. However, toxicity and severe adverse effects, particularly hepatotoxicity, limit the clinical application of triptolide. Licorice root extract contains various bioactive compounds and is potent hepatoprotective. Magnesium isoglycyrrhizinate, a magnesium salt of the 18α-glycyrrhizic acid stereoisomer of glycyrrhizic acid, is used clinically in China to treat chronic viral hepatitis and acute drug-induced liver injury...

Our group began performing erbium-YAG 2940 wavelength fractional resurfacing of burn scar in our burn center's dedicated burn operating room (OR) in January 2016. The impact of these procedures on the performance of a mature, dedicated burn OR is unknown. All burn OR cases performed between January 1, 2015 and December 31, 2015 served as a pre-laser (PRE-LSR) historical control. A postintervention cohort of laser-only cases (LSR) performed between January 1, 2016 and August 17, 2016 was then identified. PRE-LSR and LSR cases were retrospectively reviewed for OR component times, and work relative value units (wRVU) billed...

Pollinators tend to be preferentially attracted to large floral displays that may comprise more than one plant in a patch. Attracting pollinators thus not only benefits individuals investing in advertising, but also other plants in a patch through a 'magnet' effect. Accordingly, there could be an indirect fitness advantage to greater investment in costly floral displays by plants in kin-structured groups than when in groups of unrelated individuals. Here, we seek evidence for this strategy by manipulating relatedness in groups of the plant Moricandia moricandioides, an insect-pollinated herb that typically grows in patches...

Misuse of synthetic antibiotics in livestock leads to the transfer of antibiotic resistant pathogens into humans and deposits toxic residues in meat and milk. There is therefore an urgent need for safe and viable alternative approaches to improve the nutrition and wellbeing of farm animals. An alternative source that has been widely exploited is traditional Chinese herbal medicine (TCHM). These herbal medicines are an important part of the healthcare system in many Asian countries. Such herbs contain several but less toxic bioactive compounds which are generally regarded biodegradable...

Tetramethylpyrazine (TMPZ) is one of the active compounds extracted from the traditional Chinese herb Chuanxiong. Several studies have shown its anti-cancer properties. However, its functions in lung cancer and the underlying cellular mechanisms are relatively unknown. Our present study aimed to investigate the effects of TMPZ on A549 and 95D cells. The MTT assay showed that TMPZ decreased cell viability in a dose- and time-dependent manner. The results of the colony formation assay indicated that TMPZ strongly suppressed colony formation ability in A549 and 95D cells...

Echinococcosis is a worldwide anthropozoonosis which is highly endemic over large animal husbandry areas in northwestern China. The current clinical therapeutic medicine against echinococcosis is albendazole, although it caused serious side effects in patients. The component in traditional Chinese herb medicine, Sophora moorcroftiana alkaloids (SA), is thought to be a potential drug to treat echinococcosis. In order to explore the effect and mechanism of SA treatment against echinococcosis, we established animal echinococcosis model and treated rats with albendazole alone, alkaloids alone, and combined therapy...

Novel and alternative options are being adopted to combat the initiation and progression of human cancers. One of the approaches is the use of molecules isolated from traditional medicinal herbs, edible dietary plants and seeds that play a pivotal role in the prevention/treatment of cancer, either alone or in combination with existing chemotherapeutic agents. Compounds that modulate these oncogenic processes are potential candidates for cancer therapy and may eventually make it to clinical applications. Diosgenin is a naturally occurring steroidal sapogenin and is one of the major bioactive compounds found in dietary fenugreek ( Trigonella foenum-graecum ) seeds...

Lipopolysaccharide (LPS) is one of the many reasons that can cause myocardial injury. Our previous works have demonstrated that 14-3-3γ could protect myocardium against LPS-induced injury. Tetramethylpyrazine (TMP), an alkaloid found in Chinese herbs, exerts myocardial protection in many ways with multiple targets. We hypothesized that the cardioprotection of TMP against LPS-induced injury is attributed to upregulation of 14-3-3γ and improvement of mitochondrial function. To test the hypothesis, we investigated the effects of TMP on LPS-induced injury to cardiomyocytes by determining cell viability, LDH and caspase-3 activities, reactive oxygen species and MMP levels, mPTP openness, and apoptosis rate...

Abdominal aortic aneurysms (AAAs) are a chronic vascular disease characterized by pathological luminal dilation. Aortic rupture is the fatal consequence of AAAs. Ginkgo biloba extracts (GBEs), a natural herb extract widely used as food supplements, drugs, and cosmetics, has been reported to suppress development of calcium chloride-induced AAAs in mice. Calcium chloride-induced AAAs do not rupture, while angiotensin II (AngII)-induced AAAs in mice have high rate of aortic rupture, implicating potentially different mechanisms from calcium chloride-induced AAAs...
