Modulation of fried spring roll wrapper quality upon treatment of batter with maltogenic amylase, transglutaminase and bromelain.

BACKGROUND: Fried foods are favored for their unique crispiness, golden color and flavor, but they also face great challenge because of their high oil content, high calories and the existence of compounds such as acrylamide and polycyclic aromatic hydrocarbons. Long-term consumption of fried foods may adversely affect health. Therefore, it is necessary to explore fried foods with lower oil contents and a high quality to meet the demand. RESULTS: A method of enzyme treatment was explored to investigate the effects of maltogenic amylase (MA), transglutaminase (TG) and bromelain (BRO) on the physicochemical properties of the batter and the quality of fried spring roll wrapper (FSRW). The results showed that the MA-, TG- or BRO-treated batters had a significant shear-thinning behavior, especially with an increase in viscosity upon increasing TG contents. FSRW enhanced its fracturability from 419.19 g (Control) to 616.50 g (MA-6 U g-1), 623.49 g (TG-0.75 U g-1) and 644.96 g (BRO-10 U g-1). Meanwhile, in comparison with BRO and MA, TG-0.5 U g-1 endowed batter with the highest density and thermal stability. MA-15 U g-1 and TG-0.5 U g-1 displayed FSRW with uniform and dense pores, and significantly reduced its oil content by 18.05% and 25.02%, respectively. Moreover, compared to MA and TG, BRO-50 U g-1 improved the flavor of FSRW. CONCLUSION: MA, TG or BRO played a key role in affecting the physicochemical properties of the batter and the quality of FSRW. TG-0.5 U g-1 remarkly reduced the oil content of FSRW with a great potential in practical application. © 2024 Society of Chemical Industry.

Graphdiyne nanoplatforms for photothermal-ferroptosis combination therapy against glioblastoma.

Glioblastoma (GBM) is one of the most malignant tumors of the central nervous system and has a poor prognosis. GBM cells are highly sensitive to ferroptosis and heat, suggesting thermotherapy-ferroptosis as a new strategy for GBM treatment. With its biocompatibility and photothermal conversion efficiency, graphdiyne (GDY) has become a high-profile nanomaterial. Here, the ferroptosis inducer FIN56 was employed to construct GDY-FIN56-RAP (GFR) polymer self-assembled nanoplatforms against GBM. GDY could effectively load FIN56 and FIN56 released from GFR in a pH-dependent manner. The GFR nanoplatforms possessed the advantages of penetrating the BBB and acidic environment-induced in situ FIN56 release. Moreover, GFR nanoplatforms induced GBM cell ferroptosis by inhibiting GPX4 expression, and 808 nm irradiation reinforced GFR-mediated ferroptosis by elevating the temperature and promoting FIN56 release from GFR. In addition, the GFR nanoplatforms were inclined to locate in tumor tissue, inhibit GBM growth, and prolong lifespan by inducing GPX4-mediated ferroptosis in an orthotopic xenograft mouse model of GBM; meanwhile, 808 nm irradiation further improved these GFR-mediated effects. Hence, GFR may be a potential nanomedicine for cancer therapy, and GFR combined with photothermal therapy may be a promising strategy against GBM.

Mechanism of the Anti-Influenza Functions of Guizhi Granules Based on Network Pharmacology, Molecular Docking, and in Vitro Experiments.

Guizhi granules mainly treat colds and improve overall health. They are widely used in clinical practice, but their protective effect and anti-inflammatory mechanism against influenza are unclear. In this study, the therapeutic effect of Guizhi granules on influenza was verified in vitro. The active compounds, targets, and cellular pathways of Guizhi granules against influenza were predicted using network pharmacology. The protein-protein interaction and component-target networks identified 5 core targets (JUN, TNF-α, RELA, AKT1, and MAPK1) and components (dihydrocapsaicin, kumatakenin, calycosin, licochalcone A, and berberine). GO and KEGG enrichment analyses revealed the anti-influenza pathways of Guizhi granules as antiviral and anti-inflammatory pathways. Molecular docking further verified that the core targets and components have good or strong binding activity. Therefore, the active ingredients, targets, and molecular mechanisms of Guizhi granules involved in influenza treatment were elucidated.

Effect of Flavonoid and Triterpenoid Compounds on the Function of Organic Anion Transporting Polypeptide 1B3 / 中国药学杂志

OBJECTIVEP: To investigate the effect of flavonoids and triterpenoids on the function of organic anion transporting polypeptide 1B3. METHODS: Natural products such as flavonoids and triterpenoids are widely present in traditional Chinese medicine and daily diets. In the present study, CHO cells stably expressing OATP1B3 and its fluorescent substrate fluorescein methotrexate were employed to investigate the effect of 21 natural products on the function of OATP1B3. RESULTS: Mulberrin, glycyrrhetinic acid, glycyrrhizic acid, quercitrin, quercetin, and chrysanthemum stem-leaf flavonoids showed significant inhibitory effects on OATP1B3-mediated uptake of fluorescein methotrexate, with IC50 values being of 3.6, 3.8, 7.5, 9.0, 10.1 μmol•L-1, and 4.1 μg•mL-1, respectively. The IC50 value of glycyrrhetinic acid on OATP1B3 was comparable to its blood concentration in clinics, indicating an OATP1B3-mediated drug-drug interaction could occur. CONCLUSION: Some flavonoids and triterpenoids are OATP1B3 inhibitors. When patients take medications of OATP1B3 substrates, care should be taken to avoid coadmistration of drugs or food containing these inhibitors to circumvent the occurrence of adverse drug interactions.

Effects of Tannase and Ultrasound Treatment on the Bioactive Compounds and Antioxidant Activity of Green Tea Extract.

The present study investigated the effects of tannase and ultrasound treatment on the bioactive compounds and antioxidant activity of green tea extract. The single-factor experiments and the response surface methodology were conducted to study the effects of parameters on antioxidant activity of green tea extract. The highest antioxidant activity was found under the optimal condition with the buffer solution pH value of 4.62, ultrasonic temperature of 44.12 °C, ultrasonic time of 12.17 min, tannase concentration of 1 mg/mL, and ultrasonic power of 360 W. Furthermore, phenolic profiles of the extracts were identified and quantified by high-performance liquid chromatography. Overall, it was found that tannase led to an increase in gallic acid and a decrease in epigallocatechin gallate, and ultrasounds could also enhance the efficiency of enzymatic reaction.

Tumor Size Improves the Accuracy of the Prognostic Prediction of Lymph Node-Negative Gastric Cancer.

BACKGROUND: Tumor size has been regarded as the "T" stage of many solid tumors because of its effect on prognosis. However, the prognostic impact of tumor size in gastric cancer (GC) is still controversial. MATERIALS AND METHODS: A total of 436 patients with curatively resected GC and those without lymph node metastasis in our center were retrospectively enrolled. The appropriate cutoff points for tumor size were determined. Potential prognostic factors were analyzed. In addition, a pathological tumor-size (pTS) classification system was proposed to evaluate the superiority of its prognostic prediction of node-negative GC patients compared with that of the pT staging system. RESULTS: The ideal cutoff points for tumor size were 4 and 8 cm. In the multivariate analysis, tumor size was identified as an independent prognostic factor for node-negative GC patients after surgery, as was pT stage. The pTS classification was found to be more appropriate for predicting the overall survival of node-negative GC patients after curative surgery than pT stage, and the -2 log-likelihood of the pTS classification (1680.782) was smaller than the value of pT (1695.239). CONCLUSIONS: As an independent prognostic factor, tumor size should be incorporated into the pT staging system to enhance the accuracy of the prognostic prediction of node-negative GC patients.

[Electroacupuncture Treatment Conduced Before and After Surgery Is Better in Promoting Reco-very of Gastrointestinal Function in Colorectal Cancer Patients Undergoing Radical Resection].

OBJECTIVE: To investigate the effect of electroacupuncture (EA) at different time-points on postoperative gastrointestinal function in patients undergoing colorectal cancer surgery. METHODS: Eighty patients with colorectal cancer undergoing laparotomy were randomly assigned to intravenous anesthesia, EA A, EA B, and EA C groups (n＝20 cases in each group). All the patients in the four groups received intravenous anesthesia with midazolam, sufentanil, cisatracurium besylate and Propofol, postoperative gastrointestinal decompression and drug analgesia. EA (2－3 mA, 2 Hz) was applied to Zhongwan (CV 12) and Tianshu (ST 25), Neiguan (PC 6), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39) on the right side for 30 min, once (one day before surgery) in the EA A group, twice (one day and 30 min before surgery) in the EA B group, and 3 times (one day, 30 min before and one day after surgery) in the EA C group. The acupoints used after surgery were PC 6, ST 36, ST 37 and ST 39. The time of postoperative ventilation, defecation, food-intake and water drinking, stomach tube removal and abdominal drainage tube removal, the volumes of stomach tube drainage and abdominal drainage, and postoperative adverse reactions were recorded. RESULTS: The first ventilation time, after surgery in the EA C group was significantly earlier than those in the intravenous anesthesia, EA A and EA B groups (P<0.05); and the water intake and abdomicnal drainage tube removal time after surgery in the EA C group were significantly earlier than those in the intravenous anesthesia group (P<0.05). No significant differences were found among the 4 groups in the time of defecation, food intake, stomach tube removal, stomach tube drainage and abdominal drainage volumes, and numbers of patients with nausea, vomiting, fever and other adverse reactions (P>0.05)．. CONCLUSION: EA treatment combined with intravenous anesthesia conducted before and after surgery is effective in promoting the recovery of gastrointestinal function in patients undergoing colorectal cancer laparotomy, and is obviously better than simple pre-operative EA.

Local generation of hydrogen for enhanced photothermal therapy.

By delivering the concept of clean hydrogen energy and green catalysis to the biomedical field, engineering of hydrogen-generating nanomaterials for treatment of major diseases holds great promise. Leveraging virtue of versatile abilities of Pd hydride nanomaterials in high/stable hydrogen storage, self-catalytic hydrogenation, near-infrared (NIR) light absorption and photothermal conversion, here we utilize the cubic PdH0.2 nanocrystals for tumour-targeted and photoacoustic imaging (PAI)-guided hydrogenothermal therapy of cancer. The synthesized PdH0.2 nanocrystals have exhibited high intratumoural accumulation capability, clear NIR-controlled hydrogen release behaviours, NIR-enhanced self-catalysis bio-reductivity, high NIR-photothermal effect and PAI performance. With these unique properties of PdH0.2 nanocrystals, synergetic hydrogenothermal therapy with limited systematic toxicity has been achieved by tumour-targeted delivery and PAI-guided NIR-controlled release of bio-reductive hydrogen as well as generation of heat. This hydrogenothermal approach has presented a cancer-selective strategy for synergistic cancer treatment.

Noninvasive Swansea criteria are valuable alternatives for diagnosing acute fatty liver of pregnancy in a Chinese population.

BACKGROUND: This study aims to assess the diagnostic and prognostic value of Swansea criteria in diagnosing acute fatty liver of pregnancy (AFLP) in a Chinese population. METHODS: A retrospective study was conducted on 52 Chinese women diagnosed with AFLP. All selected cases were reassessed using the Swansea criteria with special focus on the noninvasive criteria, since performing a liver biopsy for this indication is rare in a Chinese population. RESULTS: Ninety point four percent of patients fulfilled five or more of the Swansea criteria. Thirty-one cases were positive for six or more Swansea criteria, but there were no significance differences between patients when using a cutoff criteria <6 or >6. When patients were positive for less than seven criteria, frequency of stillbirth, continuous blood purification (CBP) treatment, hysterectomy, and postpartum hemorrhage were not increased. However, patients who were positive for seven or more criteria had a significantly higher risk of stillbirth and a higher rate of CBP treatment (p < 0.05). Areas under the receiver operating characteristic (ROC) curve of postpartum hemorrhage was 0.670, which reached a statistical significance (p = 0.040). We observed a significantly elevated postpartum hemorrhage along with positivity of the Swansea criteria (p = 0.040). CONCLUSIONS: Swansea criteria without liver biopsy are good screening tools for AFLP diagnosis, and may be useful for assessing disease severity.

Paris Saponin VII Inhibits the Migration and Invasion in Human A549 Lung Cancer Cells.

Metastasis is the main cause of death in lung cancer. Targeting the process of metastasis is a strategy to lung cancer treatment. Trillium tschonoskii Maxim., a traditional Chinese medicine, has been used for treatment of many diseases, including cancer. This study aims to determine the anti-metastatic effect of paris saponin VII (PS VII) which was extracted from T. tschonoskii Maxim. by using human lung cancer cell line A549 cells. Our results showed that PS VII could significantly suppress the viability as well as cell migration and invasion abilities of A549 cells in a concentration-dependent manner. PS VII reduced the activity of matrix metalloproteinase-2 (MMP-2) and MMP-9 by elevating the expression of TIMP1/2. These data indicated that PS VII could reduce the metastatic capability of A549 cells, probably through up-regulating the expression of TIMP1/2. These findings demonstrated a new therapeutic potential for PS VII in anti-metastatic therapy of lung cancer. Copyright © 2015 John Wiley & Sons, Ltd.

Trillium tschonoskii steroidal saponins suppress the growth of colorectal Cancer cells in vitro and in vivo.

ETHNOPHARMACOLOGICAL RELEVANCE: Saponins of many herbs are known to possess anti-cancer effect. AIM OF THE STUDY: The present study aimed to investigate the growth inhibitory effect of Trillium tschonoskii steroidal saponins in a mouse model of colitis-associated colorectal cancer and a human colorectal cancer cell line HT-29, and isolate some major constituents and evaluate their anti-tumor activity. MATERIALS AND METHODS: Forty male ICR mice were administered with 1, 2-dimethyl-hydrazine (DMH) and dextran sodium sulfate (DSS). Ten mice were given no further treatment, the rest were administered with different doses of TTS (5, 10, 20mg/kg) orally, every three days from the 9th week to the 20th week. RESULTS: TTS effectively protected ICR mice against DMH/DSS-induced tumorigenesis. The incidence of tumor development was 90% (9/10) in the mice treated with DMH/DSS, but that was reduced to 50% (5/10), 40% (4/10), and 20% (2/10), respectively, in the mice treated with 5%, 10%, and 20% of TTS. Results of Ki-67 staining, TUNEL assay and caspase-3 activity assay revealed that TTS moderately decreased abnormal proliferation and increased apoptosis of colonic epithelial cells. It inhibited the growth and triggered the apoptosis of HT-29 cells, partly through suppressing mitogen-actived protein kinases (MAPKs) and triggering mitochondrial-mediated apoptotic pathway. Three compounds, namely, Paris saponin VII, polyphylloside III and Paris saponin VI, were important active compounds in TTS. CONCLUSION: These data suggest that TTS has a potential role in clinical prevention and treatment for colorectal cancer.

Effectiveness of dry needling for myofascial trigger points associated with neck and shoulder pain: a systematic review and meta-analysis.

OBJECTIVE: To evaluate current evidence of the effectiveness of dry needling of myofascial trigger points (MTrPs) associated with neck and shoulder pain. DATA SOURCES: PubMed, EBSCO, Physiotherapy Evidence Database, ScienceDirect, The Cochrane Library, ClinicalKey, Wanfang Data Chinese database, China Knowledge Resource Integrated Database, Chinese Chongqing VIP Information, and SpringerLink databases were searched from database inception to January 2014. STUDY SELECTION: Randomized controlled trials were performed to determine whether dry needling was used as the main treatment and whether pain intensity was included as an outcome. Participants were diagnosed with MTrPs associated with neck and shoulder pain. DATA EXTRACTION: Two reviewers independently screened the articles, scored methodological quality, and extracted data. The results of the study of pain intensity were extracted in the form of mean and SD data. Twenty randomized controlled trials involving 839 patients were identified for meta-analysis. DATA SYNTHESIS: Meta-analyses were performed using RevMan version 5.2 and Stata version 12.0. The results suggested that compared with control/sham, dry needling of MTrPs was effective in the short term (immediately to 3 days) (standardized mean difference [SMD]=-1.91; 95% confidence interval [CI], -3.10 to -.73; P=.002) and medium term (SMD=-1.07; 95% CI, -1.87 to -.27; P=.009); however, wet needling (including lidocaine) was superior to dry needling in relieving MTrP pain in the medium term (SMD=1.69; 95% CI, .40-2.98; P=.01). Other therapies (including physiotherapy) were more effective than dry needling in treating MTrP pain in the medium term (9-28d) (SMD=.62; 95% CI, .02-1.21; P=.04). CONCLUSIONS: Dry needling can be recommended for relieving MTrP pain in neck and shoulders in the short and medium term, but wet needling is found to be more effective than dry needling in relieving MTrP pain in neck and shoulders in the medium term.

Apple polysaccharide reduces NF-Kb mediated colitis-associated colon carcinogenesis.

Nuclear factor-kappa B (NF-κB) is an important molecule in mediating inflammatory colitis, which can lead to colorectal cancer (CRC). The aim of this study was to evaluate the chemopreventive efficacy of apple polysaccharide extract (AP) in inhibiting NF-κB-mediated inflammation pathways in CRC. We evaluated AP in vitro in HT-29 and SW620 human CRC cells. We also used the azoxymethane and dextran sodium sulphate (AOM/DSS) model to induce colon carcinogenesis in vivo. The chemoprotective effects of AP were assessed using Western blot, immunofluorescence assay, real-time PCR, electrophoretic mobility shift assay, and flow cytometry. AP reduced AOM/DSS-associated toxicities, prevented carcinogenesis, and decreased the expression of TLR4, MD2, MyD88, TRAM, TRIF-related adapter molecule, interferon-ß, tumor necrosis factor-α, and interleukin-6. The protective effects of AP may be related to the inhibition of TLR4/MD2-mediated signaling, including MyD88 and TRIF, as well as the inhibition of NF-κB-mediated inflammatory signaling pathways. Therefore, AP could be used in combination therapy for the prevention of colitis-associated colon cancer.

Paris saponin VII inhibits metastasis by modulating matrix metalloproteinases in colorectal cancer cells.

Metastasis is the main cause of mortality of patients with cancer-related disease. Targeting the process of metastasis has been proposed as a potential strategy in cancer treatment. Trillium tschonoskii Maxim., a traditional Chinese medicine, is used for the treatment of numerous diseases, including cancer. The current study aimed to determine the anti-metastatic effect of Paris saponin VII (PS VII), which was extracted from T. tschonoskii Maxim., using SW620 and LoVo cells, two human metastatic colorectal cancer (CRC) cell lines. The present study conducted cell attachment, wound healing and migration assays to detect the anti-metastatic effects of PS VII on colorectal cells. In addition, gelatin zymography assay and western blot analysis were used to detect the possible mechanisms involved. The results of this study demonstrated that PS VII significantly suppresses the viability, attachment, migration and invasive abilities of CRC cells in a concentration-dependent manner. In addition, PS Ⅶ reduced the expression levels and activity of matrix metalloproteinase (MMP)-2 and MMP-9. These data indicate that PS VII reduces the metastatic capability of CRC cells, possibly via the downregulation of the expression and activity of MMP-2 and MMP-9. These results demonstrate a novel therapeutic potential for PS VII in anti-metastatic therapy.
