[Tetramethylpyrazine regulates angiogenesis of endothelial cells in cerebral ischemic stroke injury via SIRT1/VEGFA signaling pathway].

This study aims to investigate whether tetramethylpyrazine(TMP) can stimulate angiogenesis in cerebral microvascular endothelial cells and alleviate cerebral ischemic stroke(CIS) and to explore the underlying mechanisms. In the animal study, adult Sprague-Dawley rats(n=15) were assigned into sham surgery(sham), middle cerebral artery occlusion/reperfusion(MCAO/R), and MCAO/R+TMP(intraperitoneal injection of 20 mg·kg~(-1)) groups. The neurological function was evaluated by the Z-Longa method. The cerebral infarction volume was detected by TTC staining. Enzyme-linked immunosorbent assay(ELISA) was employed to detect the expression of vascular endothelial growth factor(VEGF), angiopoietin(Ang), and platelet-derived growth factor(PDGF). Immunofluorescence staining was employed to detect Ki67 and the expression of vascular endothelial growth factor A(VEGFA) and slient information regulator 1(SIRT1). Western blot was employed to determine the expression levels of VEGFA, SIRT1, angiopoietin-2(Ang-2), and platelet-derived growth factor B(PDGFB). In the cell study, mouse brain-derived endothelial cells(Bend.3) were cultured, and the optimal concentration of TMP was determined. Then, VEGF, Ang, and PDGF were detected by ELISA after the addition of cabozantinib. Western blot was employed to measure the expression of VEGFA, Ang-2, and PDGFB. Immunofluorescence staining was used to detect CD31, CD34, and Ki67, and the proliferation, migration, and tube formation ability of Bend.3 cells were observed in vitro. Western blot and immunofluorescence staining were performed to measure the expression of SIRT1 and VEGFA after addition of the SIRT1-specific inhibitor selisistat(EX-527). The results showed that compared with the sham group, the MCAO/R group had severe neurological function damage, increased infarction volume, up-regulated expression of VEGF, VEGFA, Ang, Ang-2, PDGF, and PDGFB, and down-regulated expression of Ki67 and SIRT1(P<0.01). Compared with the MCAO/R group, the MCAO/R+TMP group presented alleviated neurological function damage, reduced infarction volume, and activated expression of VEGF, VEGFA, Ang, Ang-2, PDGF, PDGFB, Ki67, and SIRT1(P<0.01). The cell experiments showed that compared with the normal group, Bend.3 cells were activated by oxygen glucose deprivation/reoxygenation(OGD/R) treatment(P<0.05, P<0.01). Compared with the OGD/R group, the OGD/R+TMP group upregulated the expression levels of VEGF, VEGFA, Ang, Ang-2, PDGF, PDGFB, SIRT1, Ki67, CD31, and CD34, enhanced the angiogenic ability of Bend.3 cells without being inhibited by BMS or EX-527(P<0.05, P<0.01, P<0.001). The results suggest that TMP can activate the SIRT1/VEGFA signaling pathway to stimulate angiogenesis and alleviate CIS injury.

Effect and Safety of Herbal Medicine Foot Baths in Patients with Diabetic Peripheral Neuropathy: A Multicenter Double-Blind Randomized Controlled Trial.

OBJECTIVE: To evaluate the effect and safety of foot baths with Tangbi Waixi Decoction (TW) in treating patients with diabetic peripheral neuropathy (DPN). METHODS: It is a multicenter double-blinded randomized controlled trial. Participants with DPN were recruited between November 18, 2016 and May 30, 2018 from 8 hospitals in China. All patients received basic treatments for glycemic management. Patients received foot baths with TW herbal granules either 66.9 g (intervention group) or 6.69 g (control group) for 30 min once a day for 2 weeks and followed by a 2-week rest, as a therapeutic course. If the Toronto Clinical Scoring System total score (TCSS-TS) ⩾6 points, the patients received a total of 3 therapeutic courses (for 12 weeks) and were followed up for 12 weeks. The primary outcome was change in TCSS-TS score at 12 and 24 weeks. Secondary outcomes included changes in bilateral motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of the median and common peroneal nerve. Safety was also assessed. RESULTS: Totally 632 patients were enrolled, and 317 and 315 were randomized to the intervention and control groups, respectively. After the 12-week intervention, patients in both groups showed significant declines in TCSSTS scores, and significant increases in MNCV and SNCV of the median and common peroneal nerves compared with pre-treatment (P<0.05). The reduction of TCSS-TS score at 12 weeks and the increase of SNCV of median nerve at 24 weeks in the control group were greater than those in the intervention group (P<0.05). The number of adverse events did not differ significantly between groups (P>0.05), and no serious adverse event was related with treatment. CONCLUSION: Treatment of TW foot baths was safe and significantly benefitted patients with DPN. A low dose of TW appeared to be more effective than a high dose. (Registry No. ChiCTR-IOR-16009331).

Efficacy of Warm Acupuncture Therapy Combined with Kegel Exercise on Postpartum Pelvic Floor Dysfunction in Women.

INTRODUCTION AND HYPOTHESIS: The objective was to observe the clinical efficacy of warm acupuncture combined with Kegel exercise in treating postpartum pelvic floor dysfunction in women. METHODS: A total of 70 primiparous women with postpartum pelvic floor muscle (PFM) injury were randomly divided into a combination group (n = 35, receiving warm acupuncture at Zhibian (BL54) acupoint and Kegel exercise) and a sham control group (n = 35, receiving sham warm acupuncture and Kegel exercise). Both groups were treated three times a week for 4 consecutive weeks. The recovery of PFM strength and changes in Urethral Rotation Angle (URA), Bladder Neck Descent (BND), and Retrovesical Angle (RVA) in pelvic floor ultrasound reports, the scores of pelvic floor dysfunction-related questionnaires, and the efficacy of urinary incontinence treatment of the two groups were compared before and after treatment. RESULTS: After treatment, the recovery rates of type I and II PFM strength, pelvic floor ultrasound parameters, pelvic floor dysfunction-related scale scores, and urinary incontinence treatment efficacy in the combination group were significantly better than those in the sham control group (p < 0.05). CONCLUSION: Warm acupuncture combined with Kegel exercise can significantly improve PFM strength and promote the recovery of postpartum pelvic floor function in women.

Analysis of the Mechanism of Action of Kushen in the Treatment of Tuberculosis Based on Network Pharmacology.

Context: Drug-resistant tuberculosis (TB), especially multidrug-resistant TB, has continued to increase and pan-drug-resistant TB and even fully drug-resistant TB have emerged, bringing great challenges to the treatment of TB. Development of new, safe, and effective antituberculosis drugs is an urgent need. Objective: The study intended to evaluate the use of the network pharmacology method to comprehensively and systematically analyze the network relationship of Kushen's main components, targets, and signaling pathways, aiming to provide new ideas and clues for an in-depth study of the mechanism of Kushen's main components in the treatment of pulmonary TB. Design: The research team performed a Network pharmacology analysis. Setting: The study took place in the Department of Respiratory and Critical Care Medicine at the Third People's Hospital of Yichang City in Yichang, Hubei, China. Outcome Measures: The research team: (1) screened Kushen's active ingredients and related targets using the Traditional Chinese Medicine System Pharmacology (TCMSP) database and analysis platform; (2) used the GeneCards database and the Online Mendelian Inheritance in Man (OMIM) database to search for disease targets, (3) connected the active ingredient's targets to the disease targets to obtain predictive targets for Kushen to act against TB, (4) used the STRING database to construct a protein-protein interaction (PPI) network map, (5) used the Database for Annotation, Visualization and Integrated Discovery (DAVID) to subject the intersecting genes to gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, and (6) used the TCMSP and Protein Data Bank (PDB) databases to dock the active ingredients with target-protein molecules. Results: The research team found 45 active ingredients for Kushen and 177 target-protein genes related to active ingredients. The PPI network map of the Kushen-TB targets and found that the top 10 targets of Kushen were: (1) mitogen-activated protein kinase 8 (MAPK8); (2) protein kinase B (AKT1); (3) MAPK1, (4) estrogen receptor 1 (ESR1), (5) rel avian reticuloendotheliosis viral oncogene homolog A (RELA), (6) interleukin-6 (IL6), (7) MYC proto-oncogene, basic helix-loop-helix (bHLH) transcription factor MYC), (8) retinoid X receptor alpha (RXRA), (9) FOS proto-oncogene activator protein 1 (AP-1) transcription factor subunit (FOS), and (10) JUN proto-oncogene AP-1 transcription factor subunit (JUN). The KEGG analysis suggested that Kushen can intervene in TB through the hypoxia-inducible factor 1 (HIF-1) signaling pathway. Conclusions: The network pharmacology analysis showed that Kushen's active ingredients can play a role in the treatment of TB through the HIF-1 signaling pathway.

Effect of processing with vinegar on efficacy of Curcuma longa in treatment of dysmenorrhea in rats with syndrome of liver depression and Qi stagnation / 中国中药杂志

This study compared the effects of Curcuma longa before and after processing with vinegar on the rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation to reveal the mechanism of vinegar processing in improving the role of C. longa in soothing liver and relieving pain. The rat model of dysmenorrhea with the syndrome of liver depression and Qi stagnation was established according to the Preparation of the Animal Model of Dysmenorrhea(Draft) and the chronic unpredictable stress me-thod. The changes in the body weight, organ indexes, writhing latency, writhing score, and serum levels of six liver function indicators, sex hormones, pain factors, and blood rheological indicators were measured to evaluate the efficacy of C. longa processed with vinegar or not in treating dysmenorrhea in the rats with syndrome of liver depression and qi stagnation. Compared with the model group, the C. longa group(processed with vinegar or not) showed slow weight loss, increase in writhing latency, and decrease in writhing response(P<0.05). The inhibition rates on writhing in raw C. longa, vinegar-processed C. longa, and positive groups were 33.780%, 64.611%, and 62.466%, respectively. The significantly higher inhibition rate of the vinegar processing group indicated that vinegar-processed C. longa demonstrated more significant therapeutic effect. The vinegar-processed C. longa group showed lower levels of alanine aminotransferase(ALT), alkaline phosphatase(ALP), aspartate aminotransferase(AST), direct bilirubin(DBIL), and total bilirubin(TBIL) and higher level of albumin(ALB)(P<0.05), which indicated that vinegar processing enhanced the therapeutic effect of C. longa on liver injury. The serum levels of estradiol(E_2) and oxytocin(OT) were lower in the vinegar-processed C. longa group(P<0.05), indicating that the vinegar-processed C. longa could regulate the sex hormone levels, reduce the activity of uterine smooth muscle and contraction of uterus, and alleviate the symptoms of dysmenorrhea in rats. Moreover, the vinegar-processed C. longa group showed lower interleukin-6(IL-6) and arginine vasopressin(AVP) levels and higher beta-endorphin(β-EP) level(P<0.05), which indicated that vinegar-processed C. longa regulated the levels of pain factors to exert the pain-relieving effect. Drug intervention decreased the whole blood viscosity low-cut, medium-cut and high-cut values, plasma viscosity, whole blood reduction viscosity low-cut and high-cut values, erythrocyte cumulative pressure, and equation K value of erythrocyte sedimentation rate(P<0.05), and the vinegar-processed C. longa group outperformed other groups. This result indicated that vinegar processing enhanced the function of C. longa in improving the local blood rheology. C. longa processed with vinegar can enter the liver to relieve the da-mage to the heart, liver, kidney, and uterus, repair the liver function, and recover the sex hormone levels and immune function by regulating the levels of sex hormones and pain factors and improving the blood rheology. It activates the pain-relieving mechanism to relieve the pain, protect the liver, and fight inflammation, which is consistent with the theory that vinegar processing facilitates C. longa entering the liver to sooth liver and relieve pain.

Plant extracts in prevention of obesity.

Obesity has become a worldwide issue and is accompanied by serious complications. Western high energy diet has been identified to be a major factor contributing to the current obesity pandemic. Thus, it is important to optimize dietary composition, bioactive substances, and agents to prevent and treat obesity. To date, extracts from plants, such as vegetables, tea, fruits, and Chinese herbal medicine, have been showed to have the abilities of regulating adipogenesis and attenuating obesity. These plant extracts mainly contain polyphenols, alkaloids, and terpenoids, which could play a significant role in anti-obesity through various signaling pathways and gut microbiota. Those reported anti-obesity mechanisms mainly include inhibiting white adipose tissue growth and lipogenesis, promoting lipolysis, brown/beige adipose tissue development, and muscle thermogenesis. In this review, we summarize the plant extracts and their possible mechanisms responsible for their anti-obesity effects. Based on the current findings, dietary plant extracts and foods containing these bioactive compounds can be potential preventive or therapeutic agents for obesity and its related metabolic diseases.

Governor vessel acupuncture for acute ischemic stroke: a systematic review and meta-analysis.

BACKGROUND: Acute ischemic stroke (AIS) is the major type of stroke, which highly risks human health and life quality. Governor vessel acupuncture (GV Ac) is one specific acupoint selection treatment. This study aimed to systematically evaluate the clinical value of GV Ac in AIS patients. METHODS: Seven electronic databases were searched for all related randomized controlled trials before December 2020. The included studies should meet the following criteria: all target patients were diagnosed as AIS; the experimental group used GV Ac as the only intervention or combined with routine neurology therapy as conventional treatment; the control group received ordinary acupuncture, or the same conventional treatment as the experimental group, or both. Evaluated the quality of all included trials and performed a meta-analysis of the extracted data. RESULTS: A total of 18 trials were included, involving 1,543 AIS patients. The results showed compared to the conventional treatment, GV Ac combining with conventional therapy resulted in Barthel Index (BI) (MD =14.16, 95% CI: 7.34, 20.79) improvement, mRS (MD =-0.63, 95% CI: -0.95, -0.32, P<0.0001) decrease, better National Institute of Health Stroke Scale (NIHSS) scores (MD =-1.18, 95% CI: -1.52, -0.83), and lower China Stroke Score (CSS)/Modified Edinburgh-Scandinavia Stroke Scale (MESSS) scores (MD =-3.77, 95% CI: -4.98, -2.57). Furthermore, GV Ac could better improve activities of daily living (ADL) (MD =8.27, 95% CI: 4.29, 12.26) and neurological deficit scores (NIHSS: MD =-1.32, 95% CI: -2.18, -0.47; CSS/MESSS: MD =-4.63, 95% CI: -5.91, -3.35), when compared to the ordinary acupuncture. DISCUSSION: According to the current evidence, GV Ac for AIS's efficacy appears to be better than that of ordinary acupuncture. When combined with conventional treatment, GV Ac may increase the benefit. But limited by the methodological quality of the included studies, more strictly designed large-scale randomized controlled trials are needed. TRIAL REGISTRATION NUMBER: CRD42020203480.

Efficacy of Integrated Traditional Chinese and Western Medicine for Treating COVID-19: A Systematic Review and Meta-Analysis of RCTs.

Background: Integrated Chinese and Western medicine (integrated medicine) is routinely used in the treatment of coronavirus disease 2019 (COVID-19) in China. In this study, we undertook a systematic review and meta-analysis of published randomized controlled trials (RCTs) to evaluate the efficacy of integrated medicine therapy for patients with COVID-19. Methods: In this meta-analysis, we searched PubMed, Embase, Web of Science, SinoMed, China National Knowledge Infrastructure (CNKI), Chongqing VIP (CQVIP), and Wanfang databases from inception to April 12, 2021, to identify RCTs of integrated medicine in the treatment of COVID-19. The quality of RCTs was assessed by the Cochrane risk of bias tool. RevMan v5.3 and Stata software packages were used for statistical analysis. Results: Nineteen RCTs involving 1,853 patients met our inclusion criteria. Compared with patients treated by conventional Western medicine (CWM), patients treated by integrated medicine have a higher overall effective rate [RR = 1.17, 95% CI: (1.10, 1.26), p < 0.00001], fever disappearance rate [RR = 1.25, 95% CI: (1.04, 1.50), p = 0.02], fatigue disappearance rate [RR = 1.28, 95% CI: (1.00, 1.63), p = 0.05], and chest CT improvement rate [RR = 1.24, 95% CI: (1.14, 1.34), p < 00001]. Beneficial effects of the integrated medicine therapy were also seen in C-reactive protein (CRP) level [WMD = -4.14, 95% CI: (-6.38, -1.91), p = 0.0003] and white blood cell (WBC) count [WMD = 0.35, 95% CI: (0.11, 0.58), p = 0.004]. Subgroup analyses showed that, when the treatment time is <2 weeks, the effect of integrated medicine treatment is more obvious in improving the overall effective rate, clinical symptoms (fever, fatigue, and cough), the CRP level, and WBC count compared with that of the CWM treatment. For patients with severe and non-severe COVID-19, integrated medicine is more effective in improving fever and cough symptoms and WBC count than using CWM alone. Conclusion: The results of the current meta-analysis suggested that the integrated medicine can improve the clinical symptoms, chest CT and infection indicators of COVID-19 patients. Even if the treatment time is <2 weeks, the effect of integrated medicine in improving symptoms is more obvious compared with the treatment of CWM. However, the results should be interpreted cautiously due to the heterogeneity among the studies.

[Effect of electroacupuncture on expression of p-ERK1/2 and c-fos in spinal dorsal horn in rats with interstitial cystitis].

OBJECTIVE: To observe the effect of electroacupuncture (EA) at "Ciliao" (BL32) and "Huiyang" (BL35) on the expression of extracellular signal-regulated kinase 1/2 (p-ERK1/2) and cellular oncogene fos (c-fos) phosphorylated of spinal dorsal horn in rats with interstitial cystitis (IC). METHODS: Eighteen female Wistar rats were randomly divided into control, model and EA groups, with 6 rats in each group. The IC model was established by intraperitoneal injection of cyclophosphamide (150 mg/kg). EA (30 Hz, 1 mA) was applied to bilateral BL32 and BL35 for 20 min, once daily for 3 consecutive days. The bladder pain was measured by using a Von Frey at 48 h after modeling and 24 h after EA. The expression levels of p-ERK1/2 and c-fos protein in L6-S1 segment of spinal cord were detected by Western blot, and the expression of p-ERK1/2 and c-fos in the right spinal dorsal horn were displayed by immunofluorescence staining. RESULTS: After modeling, the bladder mechanical pain threshold (PT) was significantly decreased (P<0.05), the protein expression of p-ERK1/2 and c-fos in the spinal cord was increased (P<0.05) and the immunofluorescence surface density of p-ERK1/2 and c-fos in the right dorsal horn of spinal cord was increased (P<0.05) in the model group relevant to the control group. After EA intervention, IC-induced reduction of PT, and increases of the expression of p-ERK1/2 and c-fos as well as immunofluorescence surface density of p-ERK1/2 and c-fos were reversed in the EA group relevant to the model group (P<0.05). CONCLUSION: EA at BL 32 and BL 35 has an analgesic effect in IC rats, which may be related to its effect in down-regulating the expression of p-ERK1/2 and c-fos in spinal dorsal horn.

Targeting adenosinergic pathway enhances the anti-tumor efficacy of sorafenib in hepatocellular carcinoma.

BACKGROUND: Sorafenib is the most widely used first-line treatment for patients with advanced hepatocellular carcinoma (HCC), but such treatment provides only limited survival benefits that might be related to the immune status of distinct tumor microenvironments. A fundamental understanding of the distribution and phenotypes of T lymphocytes in tumors will undoubtedly lead to the development of novel immunotherapeutic strategies that could possibly enhance the efficacy of sorafenib treatments. METHODS: Flow cytometry, immunohistochemistry and immunofluorescence analyses were performed to detect the infiltration and distribution of various leukocyte populations, and the expression of different immune checkpoint molecules in fresh HCC tumor tissues. Correlations among indicating genes were calculated in 365 patients with HCC from The Cancer Genome Atlas (TCGA) data set, and the cumulative overall survival time was calculated using the Kaplan-Meier method. Moreover, role of adenosinergic pathway on sorafenib anti-tumor efficacy was investigated using both subcutaneous and orthotopic transplantation tumor model in immune competent C57BL/6 mice. RESULTS: We revealed that levels of CD3+ and CD8+ T cells were significantly downregulated in HCC tumor tissue, so were the infiltration of CD169+ cells (a Mφ subpopulation with T cell activation capacities) and their contact with CD8+ cells in tumor milieus. Moreover, levels of PD-1 and CD39 expression were significantly upregulated in human HCC-infiltrating CD4+ and CD8+ T cells, and CD39+CD8+ T cells exhibited a CD69+PD-1+perforinlowIFNγlow "exhausted" phenotype. Levels of both CD39+ T cells infiltration and adenosine receptor ADORA2B expression in tumor tissues were negatively correlated with overall survival of patients with HCC. Accordingly, mice treated with sorafenib in combination with adenosine A2B receptor blockage reagents exhibited significantly reduced tumor progression compared with control groups. CONCLUSIONS: These results suggest that adenosinergic pathway might represent an applicable target for sorafenib-combined-therapies in human HCC.

Consideration about chemistry, manufacture and control (CMC) key problems in simplified registration of classical traditional Chinese medicine excellent prescriptions / 中国中药杂志

As an outstanding representative of traditional Chinese medicine(TCM) prescriptions accumulated from famous TCM doctors' clinical experiences in past dynasties, classical TCM excellent prescriptions (cTCMeP) are the most valuable part of TCM system. To support the research and development of cTCMeP, a series of regulations and measures were issued to encourage its simplified registration. There is still a long-way to go because many key problems and puzzles about technology, registration and administration in cTCMeP R&D process are not resolved. Based on the analysis of registration and management regulations of botanical drug products in FDA of USA and Japan, and EMA of Europe, the possible key problems and countermeasures in chemistry, manufacture and control (CMC) of simplified registration of cTCMeP were analyzed on the consideration of its actual situation. The method of "reference decoction extract by traditional prescription" (RDETP) was firstly proposed as standard to evaluate the quality and preparation uniformity between the new developing product under simplified registration and traditional original usages of cTCMeP, instead of Standard Decoction method in Japan. "Totality of the evidence" approach, mass balance and bioassay/biological assay of cTCMeP were emphatically suggested to introduce to the quality uniformity evaluation system in the raw drug material, drug substance and final product between the modern product and traditional decoction.

Plasmakinetic resection technology for the treatment of benign prostatic hyperplasia: evidence from a systematic review and meta-analysis.

The aim of this study was to compare plasmakinetic resection of the prostate (PKRP) with transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH) in terms of efficacy and safety. Published RCTs were searched from PubMed, Embase, Science Citation Index, and Cochrane Library up to April 10, 2014. After methodological quality assessment and data extraction, meta-analysis was performed using the STATA 12.0 software. 18 reports of 16 RCTs were included in this analysis. Meta-analyses showed that PKRP significantly improved Qmax at 12 months, but no significant difference was found for other efficacy outcomes. In terms of safety, treatment of PKRP was associated with reduced drop in serum sodium, lower TUR syndrome, reduced need of blood transfusion, clot retention, and shorter catheterization time and hospital stay; in contrast, there were no significant differences in the analysis of operative time, postoperative fever, and long-term postoperative complications. In summary, current evidence suggests that, although PKRP and TURP are both effective for BPH, PKRP is associated with additional potential benefits in efficacy and more favorable safety profile. It may be possible that PKRP may replace the TURP in the future and become a new standard surgical procedure.

Gastrodin: an ancient Chinese herbal medicine as a source for anti-osteoporosis agents via reducing reactive oxygen species.

Increased levels of reactive oxygen species (ROS) are a crucial pathogenic factor of osteoporosis. Gastrodin, isolated from the traditional Chinese herbal agent Gastrodia elata, is a potent antioxidant. We hypothesized that gastrodin demonstrates protective effects against osteoporosis by partially reducing reactive oxygen species in human bone marrow mesenchymal stem cells (hBMMSCs) and a macrophage cell line (RAW264.7 cells). We investigated gastrodin on osteogenic and adipogenic differentiation under oxidative stress in hBMMSCs. We also tested gastrodin on osteoclastic differentiation in RAW264.7 cells. Hydrogen peroxide (H2O2) was used to establish an oxidative cell injury model. Our results showed that gastrodin significantly promoted the proliferation of hBMMSCs, improved some osteogenic markers, reduced lipid generation and inhibited the mRNA expression of several adipogenic genes in hBMMSCs. Moreover, gastrodin reduced the number of osteoclasts, TRAP activity and the expression of osteoclast-specific genes in RAW264.7 cells. Gastrodin suppressed the production of reactive oxygen species in both hBMMSCs and RAW264.7 cells. In vivo, we established a murine ovariectomized (OVX) osteoporosis model. Our data revealed that gastrodin treatment reduced the activity of serum bone degradation markers, such as CTX-1 and TRAP. Importantly, it ameliorated the micro-architecture of trabecular bones. Gastrodin decreased osteoclast numbers in vivo by TRAP staining. To conclude, these results indicated that gastrodin shows protective effects against osteoporosis linking to a reduction in reactive oxygen species, suggesting that gastrodin may be useful in the prevention and treatment of osteoporosis.

Identification of insecticidal constituents of the essential oils of Dahlia pinnata Cav. against Sitophilus zeamais and Sitophilus oryzae.

The aim of this research was to determine the chemical composition of the essential oils of Dahlia pinnata, their insecticidal activity against Sitophilus zeamais and Sitophilusoryzae and to isolate insecticidal constituents. Based on bioactivity-guided fractionation, active constituents were isolated and identified as D-limonene, 4-terpineol and α-terpineol. Essential oils and active compounds tested exhibited contact toxicity, with LD50 values ranging from 132.48 to 828.79 µg/cm(2) against S. zeamais and S. oryzae. Essential oils possessed fumigant toxicity against S. zeamais and S. oryzae with LC50 from 14.10 to 73.46 mg/L. d-Limonene (LC50 = 4.55 and 7.92 mg/L) showed stronger fumigant toxicity against target insects. 4-Terpineol (88 ± 8%) and d-limonene (87 ± 5%) showed the strongest repellency against S. zeamais and S. oryzae, respectively. The results indicate that essential oils and insecticidal constituents have potential for development into natural fumigants, insecticides or repellents for control of the stored-product insect pests.

Shell-crosslinked hybrid nanoparticles for direct cytosolic delivery for tumor therapy.

To obtain efficient therapeutics, drug release into the cytosol is required because drug targets are often located in the cytosol or have active sites that require intracellular machinery in the cytosolic compartment. However, typical nanocarriers gain cellular entry by endocytic mechanisms, confining the internalized nanocarriers to the endosomal-lysosomal system, thus resulting in the rapid destruction of active drugs without release into the cytosol. Herein, hybrid nanoparticles (HNs) with a core-shell structure, which was based on nanoemulsion-templates stabilized by both ß-lactoglobulin (ß-LG) and lecithin, were developed. Additionally, its formation mechanism and structure were also studied. Importantly, the HNs could directly penetrate the cell membrane and enter the cytosol, without entrapment within the endosomal-lysosomal system via the lipid raft-like pathway, thus enhancing its antitumor activities. We therefore concluded that HNs are promising targeting delivery systems for drugs, especially for pharmaceutical proteins and gene-targeting drugs.
