An advanced treatment process for 3-high wastewater discharged from crude oil storage tanks.

The wastewater discharged from crude oil storage tanks (WCOST) contains high concentrations of salt and metal iron ions, and high chemical oxygen demand (COD). It belongs to "3-high" wastewater, which is difficult for purification. In this study, WCOST treatments were comparatively investigated via an advanced pretreatment and the traditional coagulation-microfiltration (CMF) processes. After WCOST was purified through the conventional CMF process, fouling occurred in the microfiltration (MF) membrane, which is rather harmful to the following reverse osmosis (RO) membrane unit, and the effluent featured high COD and UV254 values. The analysis confirmed that the MF fouling was due to the oxidation of ferrous ions, and the high COD and UV254 values were mainly attributable to the organic compounds with small molecular sizes, including aromatic-like and fulvic-like compounds. After the pretreatment of the advanced process consisting of aeration, manganese sand filtration, and activated carbon adsorption in combination with CMF process, the removal efficiencies of organic matter and total iron ions reached 97.3% and 99.8%, respectively. All the water indexes of the effluent, after treatment by the advanced multi-unit process, meet well the corresponding standard. The advanced pretreatment process reported herein displayed a great potential for alleviating the MF membrane fouling and enhanced the lifetime of the RO membrane system in the 3-high WCOST treatment.

Study on low-temperature plasma γ-Al2O3 catalytic viscosity reduction of polyacrylamide solution.

The wide use of polyacrylamide (PAM) in enhanced oil recovery generates a large amount of polymer-bearing wastewater featuring high viscosity and difficult viscosity reduction, making the treatment of wastewater increasingly difficult. In this paper, the experimental study on reducing the viscosity of wastewater containing polyacrylamide by using the plasma generated by dielectric barrier discharge (DBD) and the synergistic effect of catalyst γ-Al2O3 is carried out. The law of plasma reducing the viscosity of wastewater containing polyacrylamide is studied under the different conditions of amounts of γ-Al2O3 catalyst, discharge voltages, and initial concentrations of polyacrylamide-containing wastewater. The mechanism of viscosity reduction of polyacrylamide is studied through environmental scanning electron microscope (ESEM), Fourier transform infrared (FTIR) spectrometer, and X-ray photoelectron spectroscopy (XPS). The results show that the catalytic viscosity reduction is the best when the discharge voltage is 18 kV and the discharge time is 15 min. With the increase in the input of the γ-Al2O3 catalyst, the viscosity of the PAM solution decreases gradually. When the amount of γ-Al2O3 is 375 mg, the shear rate changes from 0.5 1/sec to 28 1/sec, and the viscosity of the solution containing polyacrylamide changes from 434.5 mPa·s to 40.2 mPa·s. The viscosity reduction rate of the PAM solution is 90.7%. After the catalytic viscosity reduction, the functional groups of polyacrylamide do not change much. The elemental composition of the catalyst has not changed, which is still Al, C, and O.

Chlorinated bisabolene sesquiterpenoids from the whole plant of Parasenecio rubescens.

Four new chlorinated bisabolene-type sesquiterpenoids (1-4) were isolated during the phytochemical investigation of an acetone extract of the whole plant of Parasenecio rubescens. The structures of 1-4 were determined by analysis of their HRESIMS and NMR spectroscopic data, and the absolute configuration of 1 was established through single-crystal X-ray diffraction. All isolates were evaluated for their cytotoxicity against three cancer cell lines (B16 mouse melanoma, HepG2 human hepatocellular carcinoma, and MCF7 human breast adenocarcinoma), as well as their antimicrobial effects against Staphylococcus aureus, Escherichia coli, and Monilia albicans. As a result, compounds 1-4 displayed a certain degree of antimicrobial activities.

Porous Biphasic Calcium Phosphate Granules from Oyster Shell Promote the Differentiation of Induced Pluripotent Stem Cells.

Oyster shells are rich in calcium, and thus, the potential use of waste shells is in the production of calcium phosphate (CaP) minerals for osteopathic biomedical applications, such as scaffolds for bone regeneration. Implanted scaffolds should stimulate the differentiation of induced pluripotent stem cells (iPSCs) into osteoblasts. In this study, oyster shells were used to produce nano-grade hydroxyapatite (HA) powder by the liquid-phase precipitation. Then, biphasic CaP (BCP) bioceramics with two different phase ratios were obtained by the foaming of HA nanopowders and sintering by two different two-stage heat treatment processes. The different sintering conditions yielded differences in structure and morphology of the BCPs, as determined by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET) surface area analysis. We then set out to determine which of these materials were most biocompatible, by co-culturing with iPSCs and examining the gene expression in molecular pathways involved in self-renewal and differentiation of iPSCs. We found that sintering for a shorter time at higher temperatures gave higher expression levels of markers for proliferation and (early) differentiation of the osteoblast. The differences in biocompatibility may be related to a more hierarchical pore structure (micropores within macropores) obtained with briefer, high-temperature sintering.

Efficacy of vitamin D supplementation on glycemic control in type 2 diabetes patients: A meta-analysis of interventional studies.

BACKGROUND: Conflicting evidence exists on the effect of vitamin D supplementation on glucose metabolism in subjects with type 2 diabetes (T2D). Therefore, this meta-analysis focuses on the relationship between vitamin D intervention and glycaemic control in subjects with T2D. METHODS: We reviewed available randomized controlled trials (RCTs) studies from the establishment time of each database to March 31, 2018. Stata 13.0 software was used to evaluate the included literature. RESULTS: Finally, a total of 19 RCT studies involving 747 intervention subjects and 627 placebo controls were included in this meta-analysis. Meta-analysis results showed that compared with the control group, the short-term vitamin D supplementation group had a decline in hemoglobin A1c (HbA1c), insulin resistance, and insulin. The Standard Mean Difference (SMD) (95% CI [95% confidence interval]) of HbA1c, insulin resistance, and insulin were -0.17 (-0.29, -0.05), -0.75 (-0.97, -0.53), -0.57 (-0.78, -0.35), respectively with all P value <.05. But there were no significant differences in long-term follow-up vitamin D intervention. CONCLUSION: Vitamin D supplementation in T2D patients can improve HbA1c, insulin resistance, and insulin in short-term intervention, suggesting that vitamin D can be considered as a therapeutic agent along with the other treatments for T2D.

[Research on protection mode of Dao-di herbs-taking the protection mode of geographical indications as an example].

Dao-di herbs have been synonymous with quality medicinal herbs in our mind hearts since ancient times and are the essence of Chinese medicine culture. The development of genuine regional herbs faces problems such as insufficient supply of local resources and lack of competitive advantages. It is necessary to seek a suitable model to protect and develop authentic medicinal materials. The protection mode of geographical indication products has become more mature. Geographical indication(GI) products and authentic medicinal materials are all related to the origin. There is certain commonality between them. However, there are also differences between authentic Chinese herbal medicines and geographical indications, and it is unsuitable to simply equate the authentic Chinese medicinal materials with GI products. This article comprehensively combs and compares the development of the authentic Chinese herbal medicines and geographical indication products, and believes that it is necessary to fully learn from the experience of GI products and combine the characteristics of authentic medicinal materials to establish a set of protection systems that meet the characteristics of authentic medicinal materials. Through this research, it has positive significance to promote the protection and management of authentic medicinal materials.

The pathogenesis of thyroid autoimmune diseases: New T lymphocytes - Cytokines circuits beyond the Th1-Th2 paradigm.

Autoimmune thyroid disease (AITD) is one of the most common organ-specific autoimmune disorders. It mainly manifests as Hashimoto's thyroiditis (HT) and Graves' disease (GD). HT is characteristic of hypothyroidism resulting from the destruction of the thyroid while GD is characteristic of hyperthyroidism due to excessive production of thyroid hormone induced by thyrotropin receptor-specific stimulatory autoantibodies. T lymphocytes and their secretory cytokines play indispensable roles in modulating immune responses, but their roles are often complex and full of interactions among distinct components of the immune system. Dysfunction of these T cells or aberrant expressions of these cytokines can cause the breakdown of immune tolerance and result in aberrant immune responses during the development of AITDs. This review summarizes recently identified T subsets and related cytokines and their roles in the pathogenesis of AITDs with the hope to provide a better understanding of the precise roles of notably identified T subsets in AITDs and facilitate the discovery of functional molecules or novel immune therapeutic targets for AITDs.

[Species diversity of ex-situ cultivated Chinese medicinal plants].

Ex-situ conservation is an important means to protect biological genetic resources. Resource protection has received more and more attention with the continuous improvement of the comprehensive utilization of traditional Chinese medicine resources. In this paper, the research and compilation of the species list of ex-situ cultivated medicinal plants in 12 Chinese Academy of Sciences botanic gardens and 19 specialized medicinal botanic gardens in China were carried out. Based on the Species 2000(2017) and other classification databases, species diversity of medicinal plants ex-situ cultivated in these botanical gardens were analyzed. The study found that there were 16 351 higher plant species in our country, belonging to 276 families and 1 936 genera. Of these, 6 949 specieswere medicinal plants, accounting for 50.4% of the total medicinal plants. There were 1 280 medicinal plants were in threatened status, accounting for 19.6% of all threatened species in the Chinese Biodiversity Red List, with ex-situ cultivated proportion of 59.5%. And 3 988 medicinal plants were Chinese endemic species, accounting for 22.5% of all Chinese endemic species, with ex-situ cultivated proportion of 53.3%. This article has reference significance for the management and protection of medicinal plant resources.

Synchronous colorectal cancer and multiple myeloma with chest wall involvement: Is this a coincidence?

Multiple primary malignant neoplasms (MPMNs) are rare malignant neoplasms that simultaneously or successively occur in the same patient as 2 or more primary malignancies. Currently, an increasing number of cases are being reported. In general, MPMNs more commonly occur as 2 solid tumors or 2 hematological malignancies. Cases of MPMN that involve a solid tumor and a hematological malignancy are rare. Here, we report a case of synchronous colorectal cancer (CRC) and multiple myeloma (MM) with chest wall involvement. After reviewing the literature, we believe that there may be a distinct syndrome involving CRC and MM. The patient in our case study suffered refractory anemia following surgery and 2 cycles of chemotherapy. Initially, the anemia was considered to be a common manifestation of CRC in this patient. Interestingly, although he received a blood transfusion, his hemoglobin levels remained low. He later developed hematuria, proteinuria, multiple osteoporosis in the costal bones, and thrombocytopenia. These new symptoms drew our attention, and we considered a diagnosis of synchronous primary CRC and MM, with the anemia as a symptom of MM. Based on the results of a bone marrow aspirate, MM was confirmed. Therefore, when CRC is associated with refractory anemia, we should not only assume that anemia is a classical symptom of CRC, a result of chronic blood loss, nutritional deficiencies, or myelosuppression due to chemotherapy, but we should also consider that it may reflect the possibility of a coexisting hematologic malignancy. As the treatment of these 2 malignancies is different, early diagnosis and treatment based on definitive diagnosis as early as possible will be beneficial to overall prognosis.

Ischemic or toxic injury: A challenging diagnosis and treatment of drug-induced stenosis of the sigmoid colon.

A 48-year-old woman was admitted with 15-mo history of abdominal pain, diarrhea and hematochezia, and 5-mo history of defecation difficulty. She had been successively admitted to nine hospitals, with an initial diagnosis of inflammatory bowel disease with stenotic sigmoid colon. Findings from computed tomography virtual colonoscopy, radiography with meglumine diatrizoate, endoscopic balloon dilatation, metallic stent implantation and later overall colonoscopy, coupled with the newfound knowledge of compound Qingdai pill-taking, led to a subsequent diagnosis of ischemic or toxic bowel disease with sigmoid colon stenosis. The patient was successfully treated by laparoscopic sigmoid colectomy, and postoperative pathological examination revealed ischemic or toxic injury of the sigmoid colon, providing a final diagnosis of drug-induced sigmoid colon stenosis. This case highlights that adequate awareness of drug-induced colon stenosis has a decisive role in avoiding misdiagnosis and mistreatment. The diagnostic and therapeutic experiences learnt from this case suggest that endoscopic balloon expansion and colonic metallic stent implantation as bridge treatments were demonstrated as crucial for the differential diagnosis of benign colonic stenosis. Skillful surgical technique and appropriate perioperative management helped to ensure the safety of our patient in subsequent surgery after long-term use of glucocorticoids.

Increasing the miR-126 expression in the peripheral blood of patients with diabetic foot ulcers treated with maggot debridement therapy.

BACKGROUND: miR-126 may increase angiogenesis in patients with diabetic foot ulcers (DFUs) treated with maggot debridement therapy (MDT). METHODS: Real-time quantitative PCR was used to detect expression of miR-126 mRNA in the peripheral blood among the non-diabetic population, type 2 diabetes mellitus patients without DFU, and patients with DFUs of type 2 diabetes mellitus. The expression of miR-126 mRNA in the peripheral blood of patients with DFUs was observed before and after MDT. Finally, human umbilical vein endothelial cells (HUVEC) were utilized to explore miR-126 mRNA expression with maggot excretions/secretions (ES). RESULTS: In the patients with DFUs, the miR-126 mRNA expression level in the peripheral blood was less than that type 2 diabetes mellitus patients without DFU, and much lower than that in the non-diabetic population (P<0.001). The miR-126 expression level was significantly increased in those DFU patients treated with MDT (P<0.05). Finally, using HUVEC co-cultured with ES, we showed the ES increased miR-126 expression in vitro (P<0.001). CONCLUSION: MDT upregulates the miR-126 expression in the peripheral blood of patients with DFUs.

Hangover relieving effect of Sanghwang mushroom mycelium cultured in germinated buckwheat

The present study was performed to evaluate the hangover relieving effect of germinated buckwheat (GB) and Sanghwang mushroom mycelium cultured in GB (SGB). Both GB and SGB showed 1,1-diphenyl-2-picrylhydrazyl radical scavenging activities and significantly increased (p < 0.001) aldehyde dehydrogenase (ALDH) activities; up to 140% increase at concentrations of 16 µL/mL. Locomotor activity test results from alcohol-SGB and alcohol-GB groups showed improved motor activities over that of the alcohol-water group at 90 min post-administration. Both alcohol-GB and alcohol-SGB groups had significantly reduced (p < 0.001) alcohol (40.02 ± 33.38 µg/mL, 66.01 ± 22.04 µg/mL, respectively) and aldehyde (5.72 ± 0.47 µg/mL, 6.72 ± 1.70 µg/mL, respectively) concentrations in blood compared to those in the alcohol-water group (199.75 ± 33.83 µg/mL, 50.43 ± 13.88 µg/mL, respectively) at 90 min post-administration. Based on cDNA microarray analysis, expressions of ALDH genes ALDH1a7 and ALDH18a1 and cytochrome P450 (CY450) gene CYP4a30b were upregulated in the alcohol-GB and alcohol-SGB groups compared to levels in the control group. Overall, the results suggest that both GB and SGB have hangover relieving effects by reducing blood acetaldehyde levels. The molecular mechanisms may involve ALDH activation and upregulated expression of alcohol metabolism-related genes such as ALDH and CYP450.

[Inhibitory effect of jianpi-jiedu prescription-contained serum on colorectal cancer SW48 cell proliferation by mTOR-P53-P21 signalling pathway].

OBJECTIVE: To investigate the effect of jianpi-jiedu (JPJD) prescription-contained serum on colorectal cancer SW48 cell proliferation and the underlying mechanisms.
 Methods: Crude extract from JPJD was made by water extract method and the main components of crude extract from JPJD were analyzed by ultra-performance liquid phase high resolution time of flight mass spectrometry (UPLC-Q-TOF/MS). The low, medium, and high-concentration of JPJD-contained serum were prepared by the serum pharmacological method. The effect of serum containing JPJD on SW48 cell proliferation was determined by MTT assay. The cell cycle was detected by flow cytometric method. The protein levels of mammalian target of rapamycin (mTOR), phospho-mTOR, P-P53, and -P21, and the mRNA level of mTOR were examined by Western blot and RT-PCR, respectively.
 Results: Seven compounds including calycosin-7-glucoside, astragaloside, ginsenoside-Re, ginsenoside-Rb1, glycyrrhizinic acid, apigenin, atractylenolide-II were identified. MTT assays demonstrated that the SW48 cell proliferation was inhibited by medium and high concentration of JPJD-contained serum and the percentages of cells at G1 phase in SW48 cell cultured in the medium and high concentration of JPJD serum group were significantly higher than those in the control group (P<0.05). Meanwhile, the levels of mTOR mRNA and phospho-mTOR protein in the medium and high concentration of JPJD serum groups were substantially lower than those in the control group (P<0.05). Conversely, the expressions of phospho-P53 and P21 protein were significantly increased in the medium and high concentration of JPJD serum group compared with those in the control group.
 Conclusion: JPJD prescription-contained serum can inhibit SW48 cell proliferation, which may be related to mTOR-P53-P21 signaling pathways.

Anti-proliferation effects of Cistanches salsa on the progression of benign prostatic hyperplasia.

Cistanche salsa has been used in traditional medicine for the treatment of kidney deficiency, neurasthenia, sexual dysfunction diseases, and benign prostatic hyperplasia (BPH). The aim of this study was to investigate the mechanism by which C. salsa extract (CSE) elicits an anti-proliferative effect on the prostate tissue of BPH-induced rats. The effects of CSE on BPH were evaluated in terms of prostate weight, production of serum dihydrotestosterone (DHT), and the mRNA expression of 5α-reductase type 1 and type 2 in the prostate tissue of BPH-induced rats. In addition, hematoxylin and eosin (H&E) staining was performed for histological examination of prostate gland morphology, and protein expression levels in prostate tissue were investigated by western blot analysis. CSE treatment decreased prostate weight, serum DHT concentration, and the mRNA expression of 5α-reductase type 1 and type 2 in prostate tissue of BPH-induced rats. In addition, CSE treatment suppressed cell proliferation by regulating the expression levels of inflammatory-related proteins (inducible nitric oxide synthase and cyclooxygenase 2) and apoptosis-associated proteins (caspase-3 and Bcl-2 family proteins). CSE may be a potential therapeutic candidate for BPH owing to its ability to regulate the expression of inflammatory and apoptosis-related proteins.

Diterpenoids from the branch and leaf of Abies fargesii.

Five new abietane diterpenoids, named abifadines A-E (1-5), and nine known ones (6-14), together with two known podocarpenes (15 and 16), were isolated from the branch and leaf of Abies fargesii. Their structures including the relative configurations were established on the basis of extensive spectroscopic analyses. The absolute configuration of 1 was determined through single-crystal X-ray diffraction analysis with Cu Kα irradiation. All the isolates were evaluated for their in vitro cytotoxicities. Only compounds 5 and 12 exhibited weak anti-proliferative effects against three cancer cell lines (B16, MCF7, and HepG2) with IC50 values range from 14.8 to 42.8 µM. The antimicrobial activities against Staphylococcus aureus, Escherichia coli and Monilia albicans of all compounds were also tested, but none of them showed significant activities.

[Effect of jianpi-jiedu formula on tumor angiogenesis-relevant genes expression in colorectal cancer].

OBJECTIVE: To investigate the effect of the jianpi-jiedu formula (JPJD) on the expression of angiogenesis-relevant genes in colon cancer.
 Methods: Crude extract was obtained from JPJD by water extract method. The effect of JPJD crude extract on colon cancer cell proliferation capacity was determined by MTT assays. The IC50 value was calculated by GraphPad Prism5 software. Affymetrix gene expression profiling chip was used to detect significant differences in expressions of genes after JPJD intervention, and pathway enrichment analysis was performed to analyze the differentially expressed genes. Ingenuity Pathway Analysis software was applied to analyze differentially expressed genes relevant to tumor angiogenesis based on mammalian target of rapamycin (mTOR) signaling pathway and then the network diagram was built. Western blot was used to verify the protein levels of key genes related to tumor angiogenesis.
 Results: JPJD crud extract inhibited the proliferation capacity in colon cancer cells. The IC50 values in 24, 48, and 72 hours after treatment were 13.060, 9.646 and 8.448 mg/mL, respectively. The results of chip showed that 218 genes significantly upgraded, and 252 genes significantly downgraded after JPJD treatment. Most of the genes were related to the function of biosynthesis, metabolism, cell apoptosis, antigen extraction, angiogenesis and so on. There were 12 differentially expressed angiogenesis genes. IPA software analysis showed that the JPJD downregulated expression of sphingomyelin phosphodiesterase 3 (SMPD3), VEGF, vascular endothelial growth factor A (VEGFA), integrin subunit alpha 1 (ITGA1), cathepsin B (CTSB), and cathepsin S (CTSS) genes, while upregulated expressions of GAB2 and plasminogen activator, urokinase receptor (PLAUR) genes in the colorectal cancer cell. Western blot results demonstrated that JPJD obviously downregulated expressions of phospho-mTOR (P-mTOR), signal transducer and activator of transcription 3 (STAT3), hypoxia inducible factor-1α (HIF-1α), and VEGF proteins, while obviously upregulated the level of phospho-P53 (P-P53) protein.
 Conclusion: JPJD may inhibit colorectal tumor angiogenesis through regulation of the mTOR-HIF-1α-VEGF signal pathway.
