Ziyin Huatan Recipe, a Chinese herbal compound, inhibits migration and invasion of gastric cancer by upregulating RUNX3 expression.

OBJECTIVES: Ziyin Huatan Recipe (ZYHT), a traditional Chinese medicine comprised of Lilii Bulbus, Pinelliae Rhizoma, and Hedyotis Diffusa, has shown promise in treating gastric cancer (GC). However, its potential mechanism has not yet been clearly addressed. This study aimed to predict targets and molecular mechanisms of ZYHT in treating GC by network pharmacology analysis and to explore the role of ZYHT in GC both in vitro and in vivo. METHODS: Targets and molecular mechanisms of ZYHT were predicted via network pharmacology analysis. The effects of ZYHT on the expression of metastasis-associated targets were further validated by Western blot and quantitative real-time polymerase chain reaction. To explore the specific molecular mechanisms of the effects of ZYHT on migration and invasion, the runt-related transcription factor 3 (RUNX3) gene was knocked out by clustered regularly interspaced short palindromic repeats/Cas9, and lentiviral vectors were transfected into SGC-7901 cells. Then lung metastasis model of GC in nude mice was established to explore the anti-metastasis effect of ZYHT. Western blot and immunohistochemistry were used to explore the impact of ZYHT on the expression of metastasis-related proteins with or without RUNX3 gene. RESULTS: The network pharmacology analysis showed that ZYHT might inhibit focal adhesion, migration, invasion and metastasis of GC. ZYHT inhibited the proliferation, migration and invasion of GC cells in vitro via regulating the expression of metastasis-associated targets. Knocking out RUNX3 almost completely reversed the cell phenotypes (migration and invasion) and protein expression levels elicited by ZYHT. In vivo studies showed that ZYHT inhibited the metastasis of GC cells to the lung and prolonged the survival time of the nude mice. Knocking out RUNX3 partly reversed the metastasis of GC cells to the lung and the protein expression levels elicited by ZYHT. CONCLUSION: ZYHT can effectively inhibit the invasion and migration of GC in vitro and in vivo, and its molecular mechanism may relate to the upregulation of RUNX3 expression.

DL-3-n-butylphthalide ameliorates diabetes-associated cognitive decline by enhancing PI3K/Akt signaling and suppressing oxidative stress.

DL-3-n-Butylphthalide (DL-NBP), a small molecular compound extracted from the seeds of Apium graveolens Linn (Chinese celery), has been shown to exert neuroprotective effects due to its anti-inflammatory, anti-oxidative and anti-apoptotic activities. DL-NBP not only protects against ischemic cerebral injury, but also ameliorates vascular cognitive impairment in dementia patients including AD and PD. In the current study, we investigated whether and how DL-NBP exerted a neuroprotective effect against diabetes-associated cognitive decline (DACD) in db/db mice, a model of type-2 diabetes. db/db mice were orally administered DL-NBP (20, 60, 120 mg· kg-1· d-1) for 8 weeks. Then the mice were subjected to behavioral test, their brain tissue was collected for morphological and biochemical analyses. We showed that oral administration of DL-NBP significantly ameliorated the cognitive decline with improved learning and memory function in Morris water maze testing. Furthermore, DL-NBP administration attenuated diabetes-induced morphological alterations and increased neuronal survival and restored the levels of synaptic protein PSD95, synaptophysin and synapsin-1 as well as dendritic density in the hippocampus, especially at a dose of 60 mg/kg. Moreover, we revealed that DL-NBP administration suppressed oxidative stress by upregulating Nrf2/HO-1 signaling, and increased brain-derived neurotrophic factor (BDNF) expression by activating PI3K/Akt/CREB signaling in the hippocampus. These beneficial effects of DL-NBP were observed in high glucose-treated PC12 cells. Our results suggest that DL-NBP may be a potential pharmacologic agent for the treatment of DACD.

Traditional Chinese medicine integrated with chemotherapy for stage IV non-surgical gastric cancer: a retrospective clinical analysis.

OBJECTIVE: Traditional Chinese medicine (TCM) is regarded as an important treatment for gastric cancer patients, especially for those in advanced stage. To evaluate the effects of TCM treatment on gastric cancer patients, the authors performed a retrospective study to report the result of the integrated treatment of TCM with chemotherapy for stage IV non-surgical gastric cancer. METHODS: In this study, 182 patients with stage IV and non-surgical gastric cancer were retrospectively analyzed to evaluate the effects of TCM integrated with chemotherapy. Among the 182 cases, 88 cases received integrated therapy consisting of TCM and chemotherapy, while 94 cases received chemotherapy alone. The overall survival and Karnofsky performance status (KPS) score were measured as the main outcome. RESULTS: The median overall survival of the integrated therapy group and chemotherapy group were 16.9 and 10.5 months, respectively. The 1-, 3- and 5-year survival rates of integrated therapy group vs. chemotherapy group were 70% vs. 32%, 18% vs. 4%, and 11% vs. 0%, respectively. There was a significant difference between the two groups (χ2 = 42.244, P > 0.001). After six-month treatment, KPS scores of the integrated therapy group and the chemotherapy group were 75.00 ± 14.78 and 60.64 ± 21.39, respectively (P > 0.001). The Cox regression analysis showed that TCM treatment is a protective factor for patients' overall survival. CONCLUSION: This study demonstrated that TCM integrated with chemotherapy may prolong overall survival and improve survival rate and life quality of patients with stage IV non-surgical gastric cancer.

[Effect of Jinlongshe Granule Drug-containing Serum on Tube Formation, Migration and Apoptosis of Human Lymphatic Endothelial Cells in vitro].

Objective To observe the inhibitory effect of Jinlongshe Granule drug-containing serum (JG-DS) on tube formation, migration, and apoptosis of human lymphatic endothelial cells ( HLECs) in vitro. Methods JG-DS was prepared. The 3rd-passage HLECs were divided into the control group (cultured with normal saline containing serum) and the experimental group (cultured with JG-DS). After cultured for 12 h, the tube formation ability was detected by Matrigel assay, and the migration ability was determined by Transwell assay in the two groups. Cell apoptosis rate was detected by flow cytometry and Annexin-V-FITC/Pl staining method. Results The total length of tube was (3 084. 49 ?326. 27) p.m after acted by 10% JG-DS for 12 h, significantly shorter than that of the control group (7 058.93 ?4 567. 39) pm (P <0.01). The migration number of HLECs was (99 ?26), obviously lower than that of the control group (160 ?32; P <0.05). The apoptosis rate of the two groups was not statistically significant (P >0.05). Conclusion JG could inhibit the tube formation and migration of HLECs in vitro, which might be one of mechanisms for inhibiting tumor micro-lymphatics.

[Effects of Enhanced Ultraviolet B Irradiation on Photosynthetic and Antioxidant System of Sorghum Seedlings].

The UV-B radiation on the surface of our planet has been enhanced due to gradual thinning of ozone layer. The change of solar spectrum UV-B radiation will cause damage to all kinds of terrestrial plants at certain degree. In this paper, taking breeding sorghum (Sorghum bicolor (L.Moench))variety Longza No.5 as sample, 40 µW·cm-2 UV-B radiation treatment was conducted on sorghum seedlings at two-leaf and one-heart stage and different time courses; then after a 2 d recovering, photosynthetic parameters were measured with a photosynthetic apparatus; the activities of antioxidant enzymes were detected as well. Our results revealed that, as the dosages of UV-B increasing, leaf browning injury was aggravated, plants dwarfing and significantly were reduced fresh weight and dry weight were observed; anthocyanin content was significantly increased; chlorophyll and carotenoid content significantly were reduced and net photosynthetic rate and chlorophyll fluorescence parameters were decreased. Meanwhile, with the increase in UV-B dosages, stomatal conductance, intercellular CO2 concentration and transpiration rate showed "down - up - down" trend; the activities of SOD and GR presented "down - up" changes; activities of POD and CAT demonstrated "down - up - down", and APX, GPX showed an "up - down - up" pattern. It is worth to note that, under the four-dose treatment, a sharp decline in net photosynthesis in sorghum seedlings was observed at 6 h UV-B treatment (equals to 2.4 J·m-2), and an obvious turning point was also found for other photosynthetic parameters and activities of antioxidant enzymes at the same time point. In summary, the results indicated that the enhanced UV-B radiation directly accounted for the damages in photosynthesis system including photosynthetic pigment content, net photosynthetic rate and chlorophyll fluorescence parameters of sorghum; the antioxidant system showed different responses to UV-B radiation below or above 6 h treatment: ASA-GSH cycle was more sensitive to low-dose UV-B radiation, while high-dose UV-B radiation not only undermined the photosynthesis system, but also triggered plant enzymatic and non-enzymatic antioxidant systems, resulting in leaf browning and necrosis,biomass accumulation reduction, plant dwarfing and even death.

Therapeutic effect of Jinlongshe Granule () on quality of life of stage IV gastric cancer patients using EORTC QLQ-C30: A double-blind placebo-controlled clinical trial.

OBJECTIVE: To evaluate the impact of Jinlongshe Granule (, JLSG) on quality of life (QOL) of stage IV gastric cancer patients. METHODS: This randomized, double-blind and placebo-controlled clinical trial included 50 patients with advanced gastric cancer. They were equally randomized into a JLSG group and a placebo group. Patients in both groups received routine Chinese herbal decoctions according to Chinese medicine (CM) treatment based on syndrome differentiation. Patients in JLSG group received additional JLSG, and those in the placebo group received an additional placebo. In the JLSG group, 19 patients who completed the study were used for analysis. In the placebo group, finally the data of 20 patients who completed the study were used for analysis. The treatment course was at least 3 months, and the follow-up duration was at least 6 months in 5 interviews. Repeated measurements of the subscale items and individual items in European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire C30 (EORTC QLQ-C30) obtained at the 5 interviews were compared using different patient groups, changes over time and changes within one group over time independently to observe the tendency of changes in the scores. RESULTS: Using time as the variant, there was signifificant difference in 4 functional scales (physical, role, emotional and social, P<0.05), 3 symptom scales (fatigue, nausea and vomiting and pain,P<0.05) and a global health status/QOL scale (P<0.05) and 6 single symptoms dyspnoea (P>0.05), insomnia (P<0.05), appetite loss (P<0.05), constipation (P<0.05), diarrhea (P>0.05) and financial difficulties (P<0.05). There was also signifificant difference in these items between the two groups when the placebo group and group over time were used as variants (P<0.05 or P<0.01). CONCLUSION: Additional use of JLSG on the basis of routine CM treatment could improve the somatic function, role function, emotional function, social function, cognitive function and general QOL of patients with advanced gastric cancer, and relieve the symptoms of fatigue, nausea and vomiting, pain, loss of appetite and constipation.

[Effects of weile powder on bicarbonate transporters CFTR SLC26A3 and SLC26A6 in gastric ulcers of rats].

OBJECTIVE: To investigate the effects of Weile Powder (WLP) on bicarbonate transporters in rats with gastric ulcers, and to probe its functional mechanisms. METHODS: The 48 SD rats were randomly divided into the normal control group, the model group, the low dose WLP group (at the daily dose of 0.075 g/mL), the middle dose WLP group (at the daily dose of 0.150 g/mL), the high dose WLP group (at the daily dose of 0.030 g/mL), and the ranitidine group (at the daily dose of 0.030 g/mL), 8 in each group. The gastric ulcer rat model was prepared by the glacial acetic acid cauterization method. Rats in each medication group were administered from the 2nd day of modeling. Rats were sacrificed after 14-day successive medication. The protein was extracted from the ulcer tissue. The protein expressions of solute carrier26A3 (SLC26A3)and solute carrier26A6 (SLC26A6) were detected using Western blot. The gastric ulcer and its peripheral tissue were sectioned. The changes of cystic fibrosis transmembrane conductance regulator (CFTR) were measured by immunofluorescence. RESULTS: Compared with the model control group, the expression levels of SLC26A3 increased in the high dose WLP group and the ranitidine group with statistical difference (P < 0.05). The expression levels of SLC26A6 increased in the high and middle dose WLP groups and the ranitidine group with statistical difference (P < 0.05). The expression level of CFTR also obviously increased in the high and middle dose WLP groups (P < 0.01). CONCLUSION: WLP could elevate the expression levels of SLC26A6, SLC26A3, and CFTR, increase the secretion of bicarbonate, thus protecting the gastric mucosa.

Tumor interstitial fluid and gastric cancer metastasis: an experimental study to verify the hypothesis of "tumor-phlegm microenvironment".

OBJECTIVE: To extract tumor interstitial fluid (TIF) from MKN-45 gastric cancer which is similar to "muddy phlegm" in Chinese medicine and observe influences of MKN-45 tumor interstitial fluid (MKN-45 TIF) intervention on metastasis of gastric cancer and on the expressions of vascular endothelial growth factor (VEGF), kinase insert domain containing receptor (KDR), epithelial-cadherin (E-cad), cyclooxygenase-2 (COX-2), intercellular adhesion molecule-1 (ICAM-1) and telomerase genes and proteins in primary tumor tissue. METHODS: An MKN-45 tumor-bearing model was established in 50 nude mice. The modeled animals were equally randomized to 5 groups: the simple tumor-bearing group (model group), the normal saline (NS) via tail vein injection (i.v.) group (NS i.v. group), MKN-45 TIF i.v. group (TIF i.v. group), NS intraperitoneal injection (i.p.) group (NS i.p. group), and MKN-45 TIF i.p. group (TIF i.p. group). The TIF and NS intervention groups received injection (i.p. or i.v.) of MKN-45 TIF or NS twice a week, 0.2 mL at a time. After 8 weeks, the primary tumors were removed, weighed and HE stained to observe tumor metastasis. The primary tumor tissues were analyzed by immunohistochemistry and real-time quantitative PCR to detect expressions of VEGF, KDR, E-cad, COX-2, ICAM-1, and telomerase genes and proteins in different groups. RESULTS: There were significant differences in tumor weight between TIF intervention groups and the model and NS intervention groups. Tumor metastasis was observed in all 5 groups, but the tumor metastasis rate in TIF intervention groups was significantly higher than those in the model and NS intervention groups. The gene and protein expressions of gastric cancer-related factors VEGF, KDR, COX-2, ICAM-1 and telomerase were unregulated while the gene and protein expressions of E-cad were downregulated in TIF intervention groups. CONCLUSIONS: TIF promotes tumor growth, invasion and metastasis of gastric cancer. These findings provide preliminary experimental clues for verifying the hypothesis of "tumor-phlegm microenvironment".
