Ferulic Acid Induces Autophagy and Apoptosis in Colon Cancer CT26 Cells via the MAPK Pathway.

Ferulic acid (FA) is a bioactive compound found in traditional Chinese herbal medicine; for example, it is present in Xinjiang Ferula, but also in strong-flavor Chinese baijiu. FA has been shown to play a crucial role in treating oxidative stress, skin whitening, and eye diseases. In this study, the potential role of FA as a means of inducing apoptosis and inhibiting colon cancer induced by the transplantation of CT26 cells was investigated. The results show that FA adjuvant treatment caused an upregulation in the expression of genes related to autophagy while simultaneously suppressing the expression of inflammatory response elements and improving the bodyweight, glutamic pyruvic transaminase (ALT), and glutamic oxaloacetic transaminase (AST) in vivo. Furthermore, FA inhibited the proliferation of CT26 cells and induced apoptosis, specifically by activating the phosphorylation of ERK and JNK to enhance the essential proteins BCL-2 and BAX in the apoptosis pathway. These results suggest that FA could be a promising auxiliary therapeutic agent for the treatment of colon cancer. Further research is needed to better understand the mechanisms underlying the beneficial effects of FA and its synergistic effects with other compounds.

Integrated lipidomics and RNA sequencing analysis reveal novel changes during 3T3-L1 cell adipogenesis.

After adipogenic differentiation, key regulators of adipogenesis are stimulated and cells begin to accumulate lipids. To identify specific changes in lipid composition and gene expression patterns during 3T3-L1 cell adipogenesis, we carried out lipidomics and RNA sequencing analysis of undifferentiated and differentiated 3T3-L1 cells. The analysis revealed significant changes in lipid content and gene expression patterns during adipogenesis. Slc2a4 was up-regulated, which may enhance glucose transport; Gpat3, Agpat2, Lipin1 and Dgat were also up-regulated, potentially to enrich intracellular triacylglycerol (TG). Increased expression levels of Pnpla2, Lipe, Acsl1 and Lpl likely increase intracellular free fatty acids, which can then be used for subsequent synthesis of other lipids, such as sphingomyelin (SM) and ceramide (Cer). Enriched intracellular diacylglycerol (DG) can also provide more raw materials for the synthesis of phosphatidylinositol (PI), phosphatidylcholine (PC), phosphatidylethanolamine (PE), ether-PE, and ether-PC, whereas high expression of Pla3 may enhance the formation of lysophophatidylcholine (LPC) and lysophosphatidylethanolamine (LPE). Therefore, in the process of adipogenesis of 3T3-L1 cells, a series of genes are activated, resulting in large changes in the contents of various lipid metabolites in the cells, especially TG, DG, SM, Cer, PI, PC, PE, etherPE, etherPC, LPC and LPE. These findings provide a theoretical basis for our understanding the pathophysiology of obesity.

Comparable prognosis in different neonatal histidine-tryptophan-ketoglutarate dosage management.

BACKGROUND: Histidine-tryptophan-ketoglutarate (HTK) is a solution commonly used for organ transplantation. However, there is no certified fixed regimen for on-pump heart surgery in neonates. We aimed to retrospectively evaluate the outcomes related to different HTK dosages and to analyze the safety of high-dosage perfusion. METHODS: A total of 146 neonates who underwent on-pump heart surgery with single-shot HTK perfusion were divided into two groups according to HTK dosages: a standard-dose (SD) group (n = 63, 40 mL/kg < HTK ≤ 60 mL/kg) and a high-dose (HD) group (n = 83, HTK >60 mL/kg). Propensity score matching (PSM) was performed to control confounding bias. RESULTS: The SD group had a higher weight (3.7 ±â€Š0.4 vs. 3.4 ±â€Š0.4 kg, P < 0.0001), a lower proportion of complete transposition of the great artery (69.8% vs. 85.5%, P = 0.022), a lower cardiopulmonary bypass (CPB) time (123.5 [108.0, 136.0] vs. 132.5 [114.8, 152.5] min, P = 0.034), and a lower aortic x-clamp time (82.9 ±â€Š27.1 vs. 95.5 ±â€Š26.0 min, P = 0.005). After PSM, 44 patients were assigned to each group; baseline characteristics and CPB parameters between the two groups were comparable. There were no significant differences in peri-CPB blood product consumption after PSM (P > 0.05). The incidences of post-operative complications were not significantly different between the two groups. There were no significant differences in ventilation time, intensive care unit stay, and post-operative hospital stay (P > 0.05). Follow-up echocardiography outcomes at 1 month, 3 to 6 months, and 1 year showed that left ventricular ejection fraction and end-diastolic dimension were comparable between the two groups. CONCLUSIONS: In neonatal on-pump cardiac surgery patients, single-shot HD (>60 mL/kg) HTK perfusion had a comparable heart protection effect and short-term post-operative prognosis as standard dosage perfusion of 40 to 60 mL/kg. Thus, this study provides supporting evidence of the safety of HD HTK perfusion.

Photothermal Responsive Singlet Oxygen Nanocarriers for Hypoxic Cancer Cell Ablation.

Hypoxia in aggressively proliferating tumor cells has been demonstrated to restrict the efficiency of photodynamic therapy owing to its oxygen (O2 )-dependent generation of singlet oxygen (1 O2 ) from photosensitizers under light irradiation. To address this problem, we propose a small-molecule dye-based 1 O2 capturing agent, B1. B1 not only bears a near-infrared absorbing azo-boron dipyrromethene backbone, but also has 1,4-dimethylnaphthalene, which facilitates the capture of 1 O2 to form endoperoxide (B1-SO). B1-SO undergoes a reversible reaction via near-infrared photothermal stimulation, thus allowing 1 O2 release. Based on this mechanism, stable B1-SO containing micelles (B1-SO NPs) were prepared and employed as 1 O2 nanocarriers to ablate cancer cells in vitro. Taking advantage of this O2 -independent 1 O2 releasing ability, B1-SO NPs were demonstrated to have efficient cytotoxicity under near-infrared irradiation, especially in a hypoxic environment. The unique O2 -independent 1 O2 generation process of B1-SO NPs suggests they can be used as novel cancer phototherapy agents.

Collagen derived species-specific peptides for distinguishing donkey-hide gelatin (Asini Corii Colla) / 中草药·英文版

Objective: As an important food therapy product with traditional Chinese medicine (TCM) applications, donkey-hide gelatin (Asini Corii Colla, ACC) has been used for thousands of years. However, till now few effective strategy had been proposed to distinguish ACC from other animal hide gelatins, especially closely related horse- and mule-hide gelatins, which was an embarrassment of ACC quality control. Methods: Combined mass spectrometry and bioinformatic methods have been applied to identify and verify two ACC-specific peptides (Pep-1 and Pep-2) capable of distinguishing ACC from other closely related animal gelatins with high selectivity. Results: It confirmed that these two peptides could be not only used for distinguishing ACC from highly homologous horse-hide and mule-hide gelatins as well as other animal hide gelatins. Conclusion: The present study provides a simple method for species-specific peptides discovery, which can be used for assessing the quality of animal gelatin products, and ensure they are authenticable and traceable.

Tripterygium and its extracts for diabetic nephropathy: Efficacy and pharmacological mechanisms.

Diabetic nephropathy (DN) is a common but intractable diabetic microvascular complication. Tripterygium, a Chinses herb, has been proven to be effective for DN treatment. In this review, the efficacy and pharmacological mechanism of tripterygium and its extracts on DN is elucidated. Tripterygium and its extracts could effectively reduce urine protein and protect renal function. Its pharmacological mechanism involves anti-inflammation, anti-oxidation, anti-glomerulosclerosis and anti-fibrosis, which is achieved by balancing the Th1/Th2 cells, regulating macrophage infiltration, and regulating the following pathways: p38 MAPK, NF-κB, TGF-ß, Wnt/ß-catenin, Akt and Notch1. Although tripterygium and its extracts may result in some adverse effects, including liver-function damage, gastrointestinal reaction, menstrual disorders, and reproductive problems, they are considered good alternative medicines for DN if used with caution and in the proper manner.

Textual Research on Origin of Alismatis Rhizoma in China Pharmacopoeia / 中国实验方剂学杂志

This paper origin studies the origin of Alismatis Rhizoma in Chinese pharmacopoeia， and puts forward some suggestions for modification. Through the changes in the records of the source of Alismatis Rhizoma in the various versions of the Chinese Pharmacopoeia and the records of Flora of China and Materia Medica of China，it is found that the source of Alismatis Rhizoma in the Chinese Pharmacopoeia is confused. Specifically， the Chinese name of Alismatis Rhizoma does not correspond to the Latin name. As a common Chinese herbal medicine，Alismatis Rhizoma has a large market circulation. Many classic Chinese medicine prescriptions released by China Food and Drug Administration contain Alismatis Rhizoma. The development of the classic Chinese medicine prescriptions will further increase the market circulation of Alismatis Rhizoma. As a major national move to promote the development of traditional Chinese medicine， the study for classic Chinese medicine prescriptions requires defining the origin of the medicinal materials used，and the confused origin of Alismatis Rhizoma recorded in the Chinese Pharmacopoeia seriously hinder the development of the classics. Therefore，in order to regulate the origin of Alismatis Rhizoma， ensure the clinical efficacy and promote the development of classic Chinese medicine prescriptions，the confused origin of Alismatis Rhizoma in the Chinese Pharmacopoeia has to be resolved as soon as possible. Based on the analysis of the changes of Alismatis Rhizoma's producing areas in the past dynasties， it is found that the producing areas of Alismatis Rhizoma have continuous changed from Wei and Jin dynasties to present， and finally formed the current situation of Sichuan as the main producing area. In comparison of chemical composition，origin and market circulation of Alismatis Rhizoma in Sichuan Province that is the most productive， and Fujian Province that is the best quality， it is found that the two species are different in every aspects. Nowadays，Alisma plantago-aquatica occupies the majority of the market， which doesn't conform to Alisma orientale as specified in the 2015 edition of the Chinese Pharmacopoeia. Therefore， through textual research and analysis， it is suggested that both A. plantago-aquatica and A. orientale. Shall be used as the origin of Alismatis Rhizoma. In the 2015 edition of Chinese Pharmacopoeia，Cassiae Semen，Schizonepetae Herba，Aisaematis Rhizoma，Fibraureae Caulis and Ajugae Herba have the same problem. This paper provides ideas for the revision of sources of traditional Chinese medicine.

Comparative study of water characteristic components of Glycyrrhiza uralensis from three geographical regions by chemical pattern recognition combined with muti-component qualitative and quantitative analysis / 中国中药杂志

Thirty-two batches of cultivated and wild Glycyrrhiza uralensis were obtained from three geographical regions. Comparative study of water characteristic components of G. uralensis from three geographical origins was conducted by PCA,OPLS-DA chemical pattern recognition combined with LC-TOF/MS and muti-component analysis. The similarity of fingerprints of 32 batches of medicinal materials ranged from 0. 903 to 0. 999. Patterns recognition could be used to distinguish cultivated G. uralensis in Gansu and Xinjiang areas from cultivated and wild plants in Inner Mongolia. Then a total of thirty-one common constituents were identified by LC-TOF/MS analysis coupled with standard compounds information. The contents of four flavonoid glycosides and five saponins were determinated by HPLC and compared using One-way ANOVA. The results showed that there was no significant difference in the contents of 5 triterpenoid saponins among the three regions,but the contents of 4 flavonoid saponins showed the trend of Inner Mongolia >Gansu≈Xinjiang( P<0. 05). In the same Inner Mongolia region,the contents of 4 flavonoid glycosides and 5 triterpenoid saponins in wild plant was significantly higher than that in cultivated plants( P<0. 01). In addition,the contents of liquiritin,isoliquiritin,licorice-saponin A_3,22β-acetoxyl-glycyrrhizic acid and uralsaponin B in Gansu and Xinjiang were obviously lower than those in Inner Mongolia,but the contents of glycyrrhizic acid,the main component of G. uralensis,were not different in the three geographical regions. In Inner Mongolia,the contents of liquiritin,isoliquiritin,licorice-saponin A_3,licorice-saponin G_2 and glycyrrhizic acid in wild plants were significantly higher than those in cultivated plants. In conclusion,qualitative/quantitative analysis of multi-index components combined with pattern recognition could effectively evaluate the quality of cultivated and wild licorice in different regions. It was helpful for us to understand the reality of licorice in different regions,and provided scientific basis for the development and comprehensive utilization of licorice resources.

Design and implementation of Xinshenghua granule traceability system based on data authenticity / 中国中药杂志

The quality of traditional Chinese medicine affects the clinical efficacy and the market research at home or abroad, which is closely related to the standardization of production. At present, Chinese market still exist in drug quality and nonstandard production phenomenon. In addition to the existing GMP production standards, it is still necessary to ensure the authenticity and reliability of traditional Chinese medicine by means of retrospect. Based on the Xinshenghua granule, starting from the authenticity of the whole process of production, this study designs and constructs the traditional Chinese medicine traceability system which is equipped with the Internet platform by using two-dimensional code as a trace tool. By making authentic record of the production process and quality transfer, it is convenient for consumers to know the drug information. The production traceability system provides guarantee for the standardization of traditional Chinese medicine development, in order to obtain the production source，the testing quality, whereabouts and responsibility.

Expression of hypothalamic-pituitary-gonadal axis-related hormone receptors in low-grade serous ovarian cancer (LGSC).

BACKGROUND: The aim of our study was to investigate the clinical features and expression levels of hypothalamic-pituitary-gonadal axis-related hormone receptors in low-grade serous ovarian cancer (LGSC). METHODS: We retrospectively investigated the clinical features of 26 consecutive patients with LGSC who underwent primary staging or debulking surgery between April 2005 and June 2013 in our center; concomitant primary high-grade serous ovarian cancer (HGSC) patients were randomly selected at a 2:1 ratio for comparison. Tissue microarrays were constructed from the LGSC and HGSC specimens, and the expression levels of six hormone receptors in the hypothalamic pituitary-gonadal axis were analyzed by immunohistochemistry. RESULTS: The median (range) age of patients with LGSC was 54 (27-77) years. According to the FIGO staging system, the cases were distributed as follows: stage I, 6 (23.1%); stage II, 0 (0%); stage III, 19 (73.1%); and stage IV, 1 (3.8%). The 2-year and 5-year overall survival rates for LGSC were 91.8% and 67.5%, respectively. The expression levels of the hormone receptors were as follows: ER, 80.8%; PR, 34.6%; AR, 53.8%; FSHR, 84.0%; LHR, 65.4%; and GnRHR, 100%. Hormone receptor-positive patients had a better prognosis compared with hormone receptor-negative patients, but the difference was not significant. CONCLUSIONS: Our study presented a higher overall survival rate and distinctive hormone receptor expression levels of LGSC patients compared with the HGSC cohort. Patients with positive hormone receptor expression tended to have a better prognosis than the corresponding hormone receptor negative patients.

Effects of electroacupuncture at GB points on markers of osteoporosis and bodyweight in ovariectomised rats.

BACKGROUND: Based on a description of acupuncture to treat a bone disease resembling osteoporosis in the ancient text of Huangdi Neijing, we aimed to assess the effects of electroacupuncture (EA) at GB points in ovariectomised (OVX) rats. METHODS: 40 female Wistar rats were randomly divided into four groups (n=10 each): ovariectomised model group (OVX); ovariectomised group treated with EA at GB points (OVX+GB); ovariectomised group treated with EA at non-GB points (OVX+N) in the hindlimb; and a sham surgery group (Sham). Three months after ovariectomy, rats in the OVX+GB and OVX+N groups received EA treatment for 3 months. Urine, blood and femur samples were collected from each animal for analysis. RESULTS: Bodyweight (BW) in the OVX+GB group decreased after EA treatment, reaching a minimum of ∼12% below the OVX and OVX+N groups at 1 month. Concentrations of urine deoxypyridinoline, a bone resorption marker, were significantly elevated in the OVX and OVX+N groups but not the OVX+GB group. Concentrations of serum bone specific alkaline phosphatase, a bone formation marker, were significantly higher in the OVX+GB group versus the Sham and OVX groups. Bone mineral density (BMD) did not differ between the OVX, OVX+GB and OVX+N groups, but was ∼10% lower than the Sham group. However, BMD/BW in the OVX+GB group was significantly higher than in the OVX and OVX+N groups and similar to the Sham group. Histological assessment of the femur showed that EA at GB points improved the bone architecture. CONCLUSIONS: EA treatment at GB points had anti-osteoporotic effects in a rat model of osteoporosis.

Aphicidal Activity of an Ageraphorone Extract From Eupatorium adenophorum Against Pseudoregma bambucicola (Homoptera: Aphididae, Takahashi).

The bamboo aphid, Pseudoregma bambucicola, is an important insect pest of bamboo that affects normal bamboo growth and induces sooty molds. The control of P. bambucicola involves the application of chemicals, such as imidacloprid, to which many species are resistant. In this study, we isolate a novel botanical pesticide (9-oxo-10,11-dehydro-ageraphorone) from an Eupatorium adenophorum(Asteraceae: Compositae) petroleum ether extract and test the aphicidal activity of this compound against P. bambucicola in laboratory bioassay and field-based experiments. This ageraphorone compound at a concentration of 2 mg/ml caused 73.33% mortality (corrected mortality [Subtracted the mortality of the negative control]: 70%) of P. bambucicola by laboratory bioassay within 6 h. Even at lower concentrations, this compound caused greater 33% mortality (corrected mortality: 30%) of aphids. Field experiments with naturally infested bamboo plants showed that two applications of 2 mg/ml ageraphorone to infested plants completely cleared infestations within 30 d. These effects were similar to those of the positive control (imidacloprid). These results reveal that 9-oxo-10,11-dehydro-ageraphorone exhibits significant aphicidal activity against bamboo aphids. We suggest that future research be directed at developing this ageraphorone compound from E. adenophorum as an aphicidal agent for biocontrol.

Comparison of periodontal ligament anesthesia and submucosal infiltration anesthesia in healthy volunteers.

OBJECTIVE: To compare periodontal ligament anesthesia using a computer-controlled local anesthetic delivery system (C-CLADS) and submucosal infiltration anesthesia using a manually operated syringe in terms of the injection pain, anesthetic effect, anesthetic dose, and complications in healthy volunteers. METHODS: Fifty healthy volunteers, aged 18 to 56 years, were recruited from September 2012 to May 2013 in the Department of Stomatology of Peking Union Medical College Hospital. A randomized self-controlled trial was conducted by applying a periodontal ligament anesthesia on one side and conventional manual submucosal infiltration anesthesia to the other (control) side. The differences in the onset time of anesthesia, drug dosage, anesthetic effect, and the degree of injection pain were compared. The complications associated with the two anesthesia methods were also recorded. RESULTS: When using C-CLADS to perform a periodontal ligament anesthesia, the drug dosage and the severity of injection pain were significantly less than those of conventional manual infiltration anesthesia [drug dosage: (0.34±0.09)ml vs.(0.55±0.13)ml, P<0.01; VRS: 0.42±0.73 vs. 1.38±0.92, P<0.01; VAS: 1.34±1.21 vs. 3.10±1.70, P<0.01]. The anesthesia success rate was approximately 90.0%, showing no significant difference relative to conventional submucosal infiltration anesthesia. Approximately 24% of the volunteers experienced postoperative pain after periodontal ligament anesthesia. CONCLUSION: Compared with conventional submucosal infiltration anesthesia using manual syringes, periodontal ligament anesthesia performed using C-CLADS can reduce the injection pain and drug dosage while achieving a satisfactory anesthetic effect; however, a considerable proportion of cases may experience postoperative pain.

Isolation and identification of acaricidal compounds in Eupatorium adenophorum petroleum ether extract and determination of their acaricidal activity against Psoroptes cuniculi.

We used multiple silica gel column chromatography and thin-layer chromatography coupled with (1)H nuclear magnetic resonance (NMR) and (13)C NMR to separate and identify the active acaricidal ingredients in Eupatorium adenophorum petroleum ether extract. The acaricidal activity of each compound was tested against Psoroptes cuniculi in vitro. Three compounds had strong acaricidal activity against P. cuniculi in vitro. The insecticidal effect of 0.5% compound 9ß-hydroxy-ageraphorone was better than the insecticidal effect of fenvalerate, and compounds 9-oxo-ageraphorone and 9-oxo-10,11-dehydro-ageraphorone exhibited higher insecticidal effects than 9ß-hydroxy-ageraphorone. Thus, the E. adenophorum petroleum ether extract contains an effective composition of acaricides that could potentially be developed as a promising plant-origin acaricide.

Acaricidal activity of petroleum ether extracts from Eupatorium adenophorum against the ectoparasitic cattle mite, Chorioptes texanus.

In this study, we evaluated the acaricidal efficacy of extracts obtained from the plant Eupatorium adenophorum against the common cattle mite Chorioptes texanus. The results showed that 95% ethanol extracts at concentrations of 1.0, 0.5, and 0.25 g/mL (w/v) were highly toxic to C. texanus in vitro, killing 100% of mites in 4 h. Similarly, petroleum ether extracts of E. adenophorum resulted in between 80 and 100% mortality of mites in vitro at concentrations of 0.1, 0.05, and 0.025 mL/mL (v/v) within 4 h. In clinical trials, all infected individuals completely recovered after two treatments administered at 7-day intervals and remained disease-free at 60 days posttreatment. The clinical effect of treatment with E. adenophorum petroleum ether extracts was similar to that of treatment with the acaricide fenvalerate. These results indicated that E. adenophorum contains novel potential acaricidal compounds that can effectively control mites in livestock.

A system review of randomized controlled trials on treating chronic stable angina by rhodiola / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To systematically assess the efficacy and safety of Rhodiola in treating chronic stable angina pectoris.</p><p><b>METHODS</b>Our group searched the Cochrane library, PubMed, Embase, Chinese biomedical literature database (CBM), VIP database (VIP), Chinese Journal Full-text Database (CNKI) for the literature published in English and Chinese till April 2013. Randomized controlled trials (RCTs) were included on the therapeutic effect of Rhodiola or Rhodiola plus conventional Western medicine in comparison with the conventional Western medicine treatment on stable angina. Data were extracted according the data extraction form. The literature methodological quality was assessed by using the Cochrane handbook, and data analyzed by Rev-Man 5.2 Software for Meta-analysis. The effect indicators of outcomes was expressed by odds ratio (OR) and 95% CI.</p><p><b>RESULTS</b>A total of 7 randomized controlled trials, 662 cases of stable angina pectoris patients met the inclusion criteria and all published in Chinese, without one scientific design and high quality literature. Compared with the conventional Western medicine treatment, combined with oral administration of Rhodiola could improve the efficiency of anti-angina (OR = 2.49, 95% CI: 1.02 - 6.09). Combined with intravenous infusion of Rhodiola could also improve the efficacy of angina pectoris (OR = 4.86, 95% CI: 2.4 - 9.82). Oral administration of Rhodiola couldn't improve ECG efficacy (OR = 1.25, 95% CI: 0.67 - 2.34). Intravenous infusion of Rhodiola could improve the clinical efficacy (OR = 2.94, 95% CI: 1.61 - 5.35). Combined with the conventional treatment, intravenous infusion of Rhodiola could improve the whole blood viscosity (low and high shear rates) and inverse variance (IV) (-1.36 and -0.99, 95% CI: -1.65 - 1.07 and -1.26 - 0.71), but could not reduce serum fibrinogen and D-dimer level. The incidence rate of adverse reactions was higher than that of the conventional treatment combined with Rhodiola (OR = 0.1, 95% CI: 0.02 - 0.51).</p><p><b>CONCLUSIONS</b>On the basis of routine treatment, Rhodiola could further improve patients' symptoms. Combined with intravenous medication, Rhodiola could increase the ECG improvement rate, and reduce adverse reactions.
