Extraction Optimization, Characterization and Biological Activities of Polysaccharide Extracts from Nymphaea hybrid.

In this study, polysaccharide-rich Nymphaea hybrid extracts (NHE) were obtained using the ultrasound-assisted cellulase extraction (UCE) method optimized by response surface methodology (RSM). The structural properties and thermal stability of NHE were characterized by Fourier-transform infrared (FT-IR), high-performance liquid chromatography (HPLC) and thermogravimetry-derivative thermogravimetry (TG-DTG) analysis, respectively. Moreover, the bioactivities of NHE, including the antioxidant, anti-inflammatory, whitening and scratch healing activities were evaluated by different in vitro assays. NHE conveyed a good ability to scavenge against the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals and inhibit the hyaluronidase activity. NHE can effectively protect the HaCaT cells against oxidative damage by inhibiting the intracellular reactive oxygen species (ROS) production in the H2O2 stimulation assays and promoting the proliferation and migration in the scratch assays. In addition, NHE was proven to inhibit melanin production in B16 cells. Collectively, the above results seem to be the evidence needed to promote the potential of NHE to be regarded as a new functional raw material in the cosmetics or food industries.

Quality assessment of rose tea with different drying methods based on physicochemical properties, HS-SPME-GC-MS, and GC-IMS.

The purpose of this study is to compare the physicochemical properties and volatile flavor compounds of rose tea obtained by the methods of normal temperature drying, hot-air drying (HAD), and vacuum freeze-drying (VFD) and to evaluate the quality of rose tea. The physicochemical results showed that the content of ascorbic acid (VC) and the pH value was the highest in rose tea obtained by HAD. The contents of anthocyanin, proanthocyanidins, and total phenols were highest in rose tea obtained by VFD. However, there was no significant difference in total flavonoids between drying methods. The volatile organic compounds (VOCs) in rose tea with different drying methods were analyzed by headspace solid-phase microextraction-gas chromatography-mass spectroscopy (HS-SPME-GC-MS) and HS GC-ion mobility spectroscopy (HS-GC-IMS), and the flavor fingerprint of rose tea was established by principal component analysis (PCA). The concentration of VOCs in rose tea varied greatly with different drying methods. The main flavor compounds of rose tea were alcohols, esters, aldehydes, and terpenoids. HS-GC-IMS was used for the identification of volatile flavor compounds of rose tea, thereby helping to assess the quality of rose tea. In addition, the rose tea samples with different drying methods were well distinguished by PCA. This study deepens the understanding of the physicochemical properties and volatile flavor compounds of rose tea with different drying methods and provides a reference for the identification of rose tea with different drying methods. PRACTICAL APPLICATION: This study deepens the understanding of the physicochemical properties and volatile flavor compounds of rose tea with different drying methods and provides a reference for the identification of rose tea with different drying methods. It also provides an effective theoretical basis for consumers to buy rose tea.

Optimization of Fermentation Process of Pomegranate Peel and Schisandra Chinensis and the Biological Activities of Fermentation Broth: Antioxidant Activity and Protective Effect Against H2O2-induced Oxidative Damage in HaCaT Cells.

In this study, the lactobacillus fermentation process of pomegranate (Punica granatum L.) peel and Schisandra chinensis (Turcz.) Baill (PP&SC) was optimized by using the response surface method (RSM) coupled with a Box-Behnken design. The optimum fermentation condition with the maximal yield of ellagic acid (99.49 ± 0.47 mg/g) was as follows: 1:1 (w:w) ratio of pomegranate peel to Schisandra chinensis, 1% (v:v) of strains with a 1:1 (v:v) ratio of Lactobacillus Plantarum to Streptococcus Thermophilus, a 37 °C fermentation temperature, 33 h of fermentation time, 1:20 (g:mL) of a solid-liquid ratio and 3 g/100 mL of a glucose dosage. Under these conditions, the achieved fermentation broth (FB) showed stronger free radical scavenging abilities than the water extract (WE) against the ABTS+, DPPH, OH- and O2- radicals. The cytotoxicity and the protective effect of FB on the intracellular ROS level in HaCaT cells were further detected by the Cell Counting Kit-8 (CCK-8) assay. The results showed that FB had no significant cytotoxicity toward HaCaT cells when its content was no more than 8 mg/mL. The FB with a concentration of 8 mg/mL had a good protective effect against oxidative damage, which can effectively reduce the ROS level to 125.94% ± 13.46% (p < 0.001) compared with 294.49% ± 11.54% of the control group in H2O2-damaged HaCaT cells. The outstanding antioxidant ability and protective effect against H2O2-induced oxidative damage in HaCaT cells promote the potential for the FB of PP&SC as a functional raw material of cosmetics.

Removal of hERG potassium channel affinity through introduction of an oxygen atom: Molecular insights from structure-activity relationships of strychnine and its analogs.

Nux vomica has been effectively used in Traditional Chinese Medicine. The processing of Nux vomica is necessary to reduce toxicity before it can be used in clinical practice. However, the mechanism for processing detoxification is unclear. hERG channels have been subjected to a routine test for compound cardiac toxicity in the drug development process. Therefore, we examined the effects and mechanisms of strychnine and brucine, two main ingredients of Nux vomica, and their N-oxides on hERG channels. Strychnine and brucine exhibited concentration-dependent inhibition of hERG channels with IC50 values of 25.9 µM and 44.18 µM, respectively. However, their nitrogen oxidative derivatives produced by processing of Nux vomica, strychnine N-oxide and brucine N-oxide, lost their activity on hERG channels. Compared to their parent compounds, only an oxygen atom was introduced in the nitrogen oxidative isoforms to compensate for the N+ - charge, suggesting that the protonated nitrogen is the key group for strychnine and brucine binding to hERG channel. Alanine-mutagenesis identified Y652 is the most important residue for strychnine and brucine binding to hERG channel. Y652A mutation increased the IC50 for strychnine and brucine by 21.64-fold and 29.78-fold that of WT IhERG, respectively. Docking simulations suggested that the protonated nitrogen of strychnine and brucine formed a cation-π interaction with the aromatic ring of Y652. This study suggests that introduction of an oxygen to compensate for the N+ - charge could be a useful strategy for reducing hERG potency and increasing the safety margin of alkaloid-type compounds in drug development.

Rapid Screening of Active Components with an Osteoclastic Inhibitory Effect in Herba epimedii Using Quantitative Pattern-Activity Relationships Based on Joint-Action Models.

Screening of bioactive components is important for modernization and quality control of herbal medicines, while the traditional bioassay-guided phytochemical approach is time-consuming and laborious. The presented study proposes a strategy for rapid screening of active components from herbal medicines. As a case study, the quantitative pattern-activity relationship (QPAR) between compounds and the osteoclastic inhibitory effect of Herba epimedii, a widely used herbal medicine in China, were investigated based on joint models. For model construction, standard mixtures data showed that the joint-action models are better than the partial least-squares (PLS) model. Then, the Good2bad value, which could reflect components' importance based on Monte Carlo sampling, was coupled with the joint-action models for screening of active components. A compound (baohuoside I) and a component composed of compounds with retention times in the 6.9-7.9 min range were selected by our method. Their inhibition rates were higher than icariin, the key bioactive compound in Herba epimedii, which could inhibit osteoclast differentiation and bone resorption in a previous study. Meanwhile, the half-maximal effective concentration, namely, EC50 value of the selected component was 7.54 µg/mL, much smaller than that of baohuoside I-77 µg/mL-which indicated that there is synergistic action between compounds in the selected component. The results clearly show our proposed method is simple and effective in screening the most-bioactive components and compounds, as well as drug-lead components, from herbal medicines.

[Total flavonoids in Scutellaria barbata prevents NLRP3 inflammasome expression in tumor cells by affecting autologous pathway].

This paper was aimed to investigate the relationship between autophagy and NLRP3 inflammasome activation by studying the effect oftotal flavonoids in Scutellaria barbata (TF-SB) on autophagy in tumor cells and NLRP3 inflammasome, and to provide experimental evidence for further study of the anti-tumor mechanism of TF-SB. Mielanoma models were established by inoculating B16-F1 cell line to mice, and then were randomly divided into 5 groups (n=10 in each group): model control, positive control control(Rap, 1.5 mg•kg⁻¹), and TF-SB low, middle and high groups (50, 100 and 200 mg•kg⁻¹). Meanwhile, healthy C57BL/6J mice were used as normal control group (n=10). The drugs were given once daily for 2 weeks consecutively. Thirty minutes after last treatment, the determinations at endpoint were performed; pathological changes of tumor tissue were evaluated by using HE staining; protein expressions of LC3-II/LC3-I or NLRP3inflammasome/caspase-1/IL-1ß and IL-18 in tumor tissues were detected by using Western-blot; and serum levels of IL-1ß and IL-18 were detected by using Elisa kit. The results showed that the tumor cells in model group showed obvious atypia and malignant proliferation; the invasion of tumor tissue was significantly reduced, the tumor necrosis area was significantly increased, and the inflammatory reaction was significantly alleviated in positive control group and various TF-SB groups. As compared with model control group, LC3-II/LC3-I was significantly increased, while NLRP3/caspase-1/IL-1ßand IL-18 protein expressions were significantly decreased in positive control group and TF-SB groups. Serum IL-1ß and IL-18 levels in model control group were found higher than those in control group (P<0.001), but they were significantly lowered in positive control group and TF-SB groups (P<0.05, P<0.01 or P<0.001). Taken together, total flavonoids in S. barbata could effectively alter the tumor growth micro-environment by inhibiting the expression of NLRP3 inflammasome, and its anti-tumor effect may be associated with the induction of tumor cell autophagy.

Ginsenoside Rg3 induces DNA damage in human osteosarcoma cells and reduces MNNG-induced DNA damage and apoptosis in normal human cells.

Panax ginseng is a Chinese medicinal herb. Ginsenosides are the main bioactive components of P. ginseng, and ginsenoside Rg3 is the primary ginsenoside. Ginsenosides can potently kill various types of cancer cells. The present study was designed to evaluate the potential genotoxicity of ginsenoside Rg3 in human osteosarcoma cells and the protective effect of ginsenoside Rg3 with respect to N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced DNA damage and apoptosis in a normal human cell line (human fibroblasts). Four human osteosarcoma cell lines (MG-63, OS732, U-2OS and HOS cells) and a normal human cell line (human fibroblasts) were employed to investigate the cytotoxicity of ginsenosides Rg3 by MTT assay. Alkaline comet assay and γH2AX focus staining were used to detect the DNA damage in MG-63 and U-2OS cells. The extent of cell apoptosis was determined by flow cytometry and a DNA ladder assay. Our results demonstrated that the cytotoxicity of ginsenoside Rg3 was dose-dependent in the human osteosarcoma cell lines, and MG-63 and U-2OS cells were the most sensitive to ginsenoside Rg3. As expected, compared to the negative control, ginsenoside Rg3 significantly increased DNA damage in a concentration-dependent manner. In agreement with the comet assay data, the percentage of γH2AX-positive MG-63 and U-2OS cells indicated that ginsenoside Rg3 induced DNA double-strand breaks in a concentration-dependent manner. The results also suggest that ginsenoside Rg3 reduces the extent of MNNG-induced DNA damage and apoptosis in human fibroblasts.

[Clinical observation on ankylosing spondylitis treated with acupoint catgut embedding combined vessel pricking therapy].

OBJECTIVE: To explore the efficacy and safety of acupoint catgut embedding combined with vessel pricking therapy for ankylosing spondylitis (AS). METHODS: Eighty-six cases of AS were randomly divided into an acupoint catgut embedding combined vessel pricking group (group A) and a medication group(group B), 43 cases in each group. In the group A, acupoint catgut embedding combined with vessel pricking therapy were applied at Shenshu(BL 23), Dazhu (BL 11) and Jiaji (EX-B 2) etc. The group B was treated with oral administration of Sulfasalazine (SASP). The treatment lasted for 8 weeks. Symptom score, Visual Analogue Scale(VAS), the indices of morning stiff duration, Schober test, occiput to wall distance, chest expansion, erythrocyte sedimentation rate (ESR) and C-response protein (CRP) were compared before and after treatment between two groups. RESULTS: After treatment, the total effective rate was 83.7% (36/43) in the group A, which was superior to that of 70.0% (28/40) in the group B (P < 0.05). The improvements of all indices in two groups were more significant than those before treatment (all P < 0.01), and symptom score, Schober test score and VAS score in group A were superior to those in the group B (P < 0.01, P < 0.05). No adverse reaction occurred in the group A. CONCLUSION: The therapeutic effect of acupoint catgut embedding combined with vessel pricking therapy for AS is preferable without any adverse effects, which is superior to that of oral administration of SASP.

The roles of the sympathetic nervous system in osteoporotic diseases: A review of experimental and clinical studies.

With the rapid aging of the world population, the issue of skeletal health is becoming more prominent and urgent. The bone remodeling mechanism has sparked great interest among bone research societies. At the same time, increasing clinical and experimental evidence has driven attention towards the pivotal role of the sympathetic nervous system (SNS) in bone remodeling. Bone remodeling is thought to be partially controlled by the hypothalamus, a process which is mediated by the adrenergic nerves and neurotransmitters. Currently, new knowledge about the role of the SNS in the development and pathophysiology of osteoporosis is being generated. The aim of this review is to summarize the evidence that proves the involvement of the SNS in bone metabolism and to outline some common osteoporotic diseases that occur under different circumstances. The adrenergic signaling pathway and its neurotransmitters are involved to various degrees of importance in the development of osteoporosis in postmenopause, as well as in spinal cord injury, depression, unloading and the complex regional pain syndrome. In addition, clinical and pharmacological studies have helped to increase the comprehension of the adrenergic signaling pathway. We try to individually examine the contributions of the SNS in osteoporotic diseases from a different perspective. It is our hope that a further understanding of the adrenergic signaling by the SNS will pave the way for conceptualizing optimal treatment regimens for osteoporosis in the near future.

OBJECTIVE: To observe therapeutic effect of using medicinal moxa stick moxibustion for treatment of tinea pedis. METHODS: One hundred and forty-four cases were randomly divided into a medicinal moxa stick group (MMS), a moxa stick group (MS) and a Nitramisole cream group (NC) (n = 48 in each group). The moxibustion method was applied in both MMS group and MS group. The Nitramisole cream was applied in NC group. The treatment course was lasted for 21 days. The symptoms of patients with tinea pedis were recorded and scored before and after the treatment course, the effectiveness was assessed. RESULTS: The total effective rates were 89.59% and 81.25% in the MMS group and the MS group, respectively, with no significant difference between the two groups (P > 0.05). However, the total effective rate in these two groups were better than that of NC group (70.84%, P < 0.05). CONCLUSION: The therapeutic effect of medicinal moxa stick moxibustion is better than that of moxa stick moxibustion or Nitramisole cream.

Osteogenic potential and responsiveness to leptin of mesenchymal stem cells between postmenopausal women with osteoarthritis and osteoporosis.

The aim of this study was to compare the osteogenic potential and responsiveness to leptin of mesenchymal stem cells (MSCs) from bone marrow between postmenopausal women with osteoarthritis (OA) and osteoporosis (OP). MSCs of the proximal femur from OA and OP donors were cultured under control and different experimental mediums. After verifying the availability of primary cells, their osteogenic potential and responsiveness to leptin were compared between two groups. Similar patterns of cell growth were shown in both OA and OP groups. However, after the sixth passage, the viability of undifferentiated cells decreased more in OP than in OA donors. Under the same osteogenic supplements condition, the mRNA expression of osteogenesis-specific genes, osteocalcin (OC) and alkaline phosphatase (ALP) were higher in OA group. Comparison of bone matrix mineralization was parallel to that of mRNA expression. The level of bone-specific ALP (BAP) was higher in cells from donors with OA, whereas osteoprotegerin (OPG) was higher in OP group. This difference in BAP expression proved to be insignificant after the administration of leptin. Although leptin upregulated the expression of OPG, a significant difference still existed between OA and OP. In conclusion, differential osteogenic potential and responsiveness to leptin of MSCs were noted between postmenopausal women with OA and OP. Differential biological behavior of MSCs seems to be partly related to the different distribution of bone mass between OA and OP populations.
