Objective: To investigate the efficacy of bifidobacterium triple viable capsules combined with quadruple therapy for patients with Helicobacter. pylori (Hp)-pos. chronic superficial gastritis and effects on inflammation-oxidative stress. Methods: From Jan. 2017 to Oct. 2018, 152 patients with Hp-pos. CSG who admitted to our department were enrolled and randomly assigned to the observation group and the control group, with 76 cases in each group. Both groups were treated conventionally. The control group received standard quadruple therapy (rabeprazole sodium enteric coated capsule + colloidal pectin bismuth dry suspension + clarithromycin sustained release tablets + amoxicillin dispersible tablets), the observation group received bifidobacteria triple viable capsules therapy on the basis of the control group, the course of treatment was 2 mo for both groups. At the end of treatment, the clin. efficacy and Hp eradication were compared between the two groups. Serum inflammation indicators [interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α)] and oxidative stress indicators [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH-Px)] were detected before and after treatment. Results: The total effective rate and Hp eradication rate of the observation group were 98.68% and 89.47%, higher than 88.16%, 69.74% of the control group (P<0.05). After treatment, the serum levels of NF-κB, IL-4, IL-6, IL-8, TNF-α and MDA in the observation group were lower than those in the control group, while IL-10, SOD and GSH-Px were higher than the control group (P<0.05). After 6 mo of follow-up, the recurrence rate of the observation group was 10.67%, which was lower than 26.87% of the control group (P<0.05). Conclusion: Bifidobacterium triple viable capsules combined with quadruple therapy for the treatment of Hp-pos. CGS is effective, which can inhibit inflammation and oxidative stress damage and reduce the risk of recurrence.

And the article was included in Fenxi Ceshi Xuebao in 2012.Name: 1,2-Dimethyl-3-propyl-1H-imidazol-3-ium hexafluorophosphate(V) The following contents are mentioned in the article:

A reversed-phase ion-pair chromatog. method using direct conductivity detection was developed for the determination of hexafluorophosphate(PF^–₆) ionic liquid anion. Chromatog. separation was performed on a Diamonsil C₁₈ reversed-phase column using ion-pair reagent-citric acid-acetonitrile as mobile phase. The effects of ion-pair reagent, volume fraction of acetonitrile, pH and column temperature on the retention factor and separation of PF^–₆ were investigated. The mechanism of retention in the separation was discussed. The optimized chromatog. conditions for the determination of PF^–₆ were using 0.05 mmol/L tetrabutylammonium hydroxide(TBAH)-0.038 mmol/L citric acid-35% acetonitrile(pH 5.5) as mobile phase, at a flow rate of 1.0 mL/min and a column temperature of 40°C. Under the optimal conditions, the retention time of PF^–₆ was less than 15 min and the baseline separation of PF^–₆ was achieved without any interference by other common anions(Cl^–, NO^–₃, F^–, Br^–, SO^-2₄ and BF^–₄). The detection limit(S/N=3) for PF^–₆ was 0.25 mg/L. The good linear relationship was obtained between chromatog. peak area and concentration of PF^–₆ in the range of 0.5-100.0 mg/L. The relative standard deviations(RSD, n=5) of chromatog. peak area and retention time were 0.17% and 0.15%, resp. The proposed method was applied in the determination of PF^–₆ in ionic liquids of 1-butyl-3-methylimidazolium hexafluorophosphate and 1-propyl-2, 3-dimethylimidazolium hexafluorophosphate. The spiked recoveries of PF^–₆ were 99% and 104%, resp. The good linearity and repeatability of the method could meet the requirements for the quant. anal. of PF^–₆ in ionic liquids The method is simple, accurate, reliable and practical.

Background: Behcet’s disease (BD) is a chronic immune disease that involves multiple systems. As the pathogenesis of BD is not clear, and new treatments are needed, we used bioinformatics to identify potential drugs and validated them in mouse models. Methods: Behcet’s disease-related target genes and proteins were screened in the PubMed and UVEOGENE databases. The biol. functions and pathways of the target genes were analyzed in detail by Gene Ontol. (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. A protein-protein interaction (PPI) network was constructed by the STRING database, and hub genes were identified by the Cytoscape plug-in CytoHubba. Gene-drug interactions were identified from the DGIdb database. Exptl. autoimmune uveitis (EAU) mice were used as an animal model for drug validation. Results: A total of 249 target genes and proteins with significant differences in BD were screened, and the results of functional enrichment anal. suggested that these genes and proteins were more located on the cell membrane, involved in regulating the production of cytokines and affecting the activity of cytokines. They mainly regulated “Cytokine- Cytokine receptor interaction”, “Inflammatory bowel disease (IBD)” and “IL-17 signaling Pathway”. In addition, 10 hub genes were obtained through PPI network construction and CytoHubba anal., among which the top 3 hub genes were closely related to BD. The DGIdb anal. enriched seven drugs acting together on the top 3 hub genes, four of which were confirmed for the treatment of BD or its complications. There is no evidence in the research to support the results in omeprazole, rabeprazole, and celastrol. However, animal experiments showed that rabeprazole and celastrol reduced anterior chamber inflammation and retinal inflammation in EAU mice. Conclusions: The functional anal. of genes and proteins related to BD, identification of hub genes, and validation of potential drugs provide new insights into the disease mechanism and potential for the treatment of BD.

Chimeric antigen receptor T cell (CAR-T) therapy has emerged as highly effective in relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL), but only about 40% patients have achieved sustained responses. Here, we conducted a phase II clin. trial testing efficacy and toxicities of CAR-T therapy in R/R non-Hodgkin’s lymphoma patients (NCT03196830). Among enrolled patients, 33 R/R DLBCL patients pretreated with DFC (decitabine, fludarabine plus cyclophosphamide) lymphodepletion chemotherapy and infused with tandem CD19-CD22 based CAR-T cells were drawn out for efficacy and toxicities of CAR-T therapy evaluation. With a median follow-up of 10.9(0.6-29.0) months, the best overall response and complete remission (CR) rates were 90.9% and 63.6%, resp. The median progression-free survival (PFS) was 10.2 mo and overall survival (OS) was undefined. The 2- year OS and PFS rates were 54.3% and 47.2%, resp. No severe grade 4 cytokine release syndrome (CRS) was observed and grade 3 CRS was observed in only 7 patients; 3 patients developed mild immune effect or cell-associated neurotoxic syndrome. All toxicities were transient and reversible and no CART-related mortality. Further subgroup anal. showed that achieving CR was an independent prognostic factor associated with favorable PFS and OS. The 2- year OS and PFS for patients who achieved CR within 3 mo (undefined vs. undefined P = 0.021 and undefined vs. undefined P = 0.036) or during the follow-up period were significantly longer than those who did not (undefined vs. 4.6 mo P < 0.0001 and undefined vs. 2.0months P<0.001). While severe CRS was also an independent prognostic factor but associated with inferior PFS and OS. The 2-yr OS and PFS for patients with grade 3 CRS were significantly shorter than those with grade 0-2 CRS (4.1 mo vs. undefined P<0.0001 and 1.7 mo vs. undefined P = 0.0002). This study indicated that CD19/CD22 dual-targeted CAR-T therapy under a decitabine-containing lymphodepletion regimen may be a safe, potent effective approach to R/R DLBCL patients.

Under the direction of large conjugated organic species, a series of novel iodobismuthates(III), [Me₃BIP][BiI₆] (1, Me₃BIP = N,N’,N”-trimethyl-3,5-bis(imidazole-1-yl)pyridine), [Me₃BIP][Bi₂I₉] (2), [Me₃TIP][Bi₂I₉] (3, Me₃TIP = N,N’,N”-trimethyl-tris[4-(1H-imidazole-1-yl)-phenyl]amine), and [Me₃TIB][Bi₂I₉] (4, Me₃TIB = N,N’,N”-trimethyl-1,3,5-tris(1-imidazolyl)benzene), were synthesized via the solvothermal method. These iodobismuthates display two types of structures: 1 contains a [BiI₆]^3- monometallic unit, and 2–4 possess binuclear [Bi₂I₉]^3- clusters, which are formed by two BiI₆ octahedra via face-sharing. The reactants BIP, TIP, and TIB were in situ transformed into [Me₃BIP]³⁺ in 1 and 2, [Me₃TIP]³⁺ in 3, and [Me₃TIB]³⁺ in 4 through the direct N-methylation reaction. UV-visible spectra analyses imply that all compounds possess potential semiconductor properties with narrow band gaps of 2.14, 2.02, 2.09, and 2.07 eV for 1–4, resp. Compound 3 has high visible-light-driven photocatalytic degradation activity and good recyclability to organic pollutants. Radical trapping experiments combined with theor. calculations show that the conjugated organic cations contribute to the narrow band gaps of the semiconductors, which can efficiently restrain the recombination of photogenerated electron-hole pairs, resulting in a good photocatalytic efficiency and stability under visible-light irradiation It is expected that the work will shed useful insights in exploitation of novel halometallates with narrow energy gaps by employing large conjugated organic templates.

Inhibition of Cytochrome P450 Enzyme and Drug-Drug Interaction Potential of Acid Reducing Agents Used in Management of CDK Inhibitors for Breast Cancer Chemotherapy. was written by Patil, Prajakta Harish;Jagadish, Puralae Channabasavaiah;Fatima, Fajeelath;Birangal, Sumit;Shenoy, Gurupur Gautham;Rao, Mahadev;Farooqui, Junaid;Rastogi, Himanshu;Sharma, Tarun;Pinjari, Jakir. And the article was included in Current drug metabolism in 2022.Product Details of 117976-90-6 The following contents are mentioned in the article:

BACKGROUND AND OBJECTIVE: Concurrent usage of proton pump inhibitors and their effect on survival and medication termination has been found in individuals receiving protein kinase inhibitor chemotherapy. To investigate the drug-drug interaction mechanism between CDK inhibitors and proton pump inhibitors, the in-silico docking approach was designed by applying computer simulation modules to predict the binding and inhibitory potential. METHODS: The interaction potential of proton pump inhibitors and CDK inhibitors was predicted utilising molecular docking techniques that employed Schrödinger algorithms to capture the dynamics of the CYP450 enzyme-inhibitor interaction between proton pump inhibitors and CDK inhibitors. Additionally, the human liver microsomes assay was used to determine the in vitro half-maximal inhibitory concentration (IC₅₀) of proton pump inhibitors and the inactivation of CDK inhibitors via CYP3A4. RESULTS: Proton pump inhibitors alter the conformation of the CYP3A4 and CYP2C19 enzymes and interact with the heme prosthetic group, as determined by docking studies. It may result in the suppression of CDK inhibitors’ metabolism via competitive inhibition at the binding site of an enzyme. Omeprazole and rabeprazole both significantly block midazolam’s 1′-hydroxylation by CYP3A4 in vitro, with IC₅₀ values of 9.86μM and 9.71μM, respectively. When omeprazole and rabeprazole are co-incubated in human liver microsomes at a 30μM concentration equivalent to the C_max of omeprazole and rabeprazole, rabeprazole significantly prolongs the metabolic clearance of palbociclib, whereas omeprazole affects the ribociclib CYP3A4-mediated metabolism. CONCLUSION: Using dynamic models, we determined that proton pump inhibitors such as rabeprazole and omeprazole indeed have the potential to cause clinically significant drug-drug interactions with CDK inhibitors in the treatment of estrogen receptor (ER) positive and HER2-positive breast cancer. As a result, it is suggested to use caution when prescribing proton pump inhibitors to these individuals.

Resistance to obinutuzumab-induced antibody-dependent cellular cytotoxicity caused by abnormal Fas signaling is overcome by combination therapies was written by Kawasaki, Natsumi;Yamashita-Kashima, Yoriko;Fujimura, Takaaki;Yoshiura, Shigeki;Harada, Naoki;Kondoh, Osamu;Yoshimura, Yasushi. And the article was included in Molecular Biology Reports in 2022.Formula: C16H21Cl2N3O2 The following contents are mentioned in the article:

Obinutuzumab, a Type II anti-CD20 antibody, is used to treat follicular lymphoma. A major mode of action of obinutuzumab is antibody-dependent cellular cytotoxicity (ADCC). Knowledge of the mechanisms of resistance to obinutuzumab is important for the development of next-line strategies to follow obinutuzumab-containing therapy, including obinutuzumab retreatment. Unfortunately, the mechanisms by which tumor cells acquire resistance to ADCC are still poorly understood. To address this, we examined the mechanisms of resistance to obinutuzumab-induced ADCC and the combination efficacy of obinutuzumab and clin. available agents in the established resistant cells. Methods and results: We established cells resistant to obinutuzumab-induced ADCC using the non-Hodgkin lymphoma cell line RL and examined their mechanisms of resistance and the combination efficacy of obinutuzumab and clin. available agents. Comprehensive anal. by RNA sequencing of resistance mechanisms revealed that abnormal Fas signaling decreased sensitivity to ADCC in resistant clones. Combination treatment with prednisolone, a component of CHOP and CVP, was found to enhance ADCC sensitivity of RL cells and resistant clones and to significantly suppress tumor growth in xenograft models. Treatment with prednisolone upregulated expression of CD20 and an apoptosis-inducing protein BIM, which might augment perforin/granzyme B-mediated cell death. Furthermore, pretreatment of the effector cells with bendamustine enhanced ADCC activity, and treatment with obinutuzumab plus bendamustine showed significant antitumor efficacy in xenograft models. It was speculated that bendamustine upregulates ADCC activity by potentiating granules-mediated cell killing. Our study revealed a novel mechanism underlying obinutuzumab-induced ADCC resistance and indicated that ADCC resistance could be overcome by combining obinutuzumab with prednisolone or bendamustine. This study provides a scientific rationale for obinutuzumab-retreatment in combination with clin. available chemotherapeutic agents for obinutuzumab resistant follicular lymphoma.

The development of synthesis methods to produce efficient anodes for wastewater treatment systems is an important industrial issue. Here, we describe the synthesis and the phys. and electrochem. characterization of Ti/(RuO₂)_0.8-(Sb₂O₄)_0.2 anodes prepared by thermal decomposition The electrodes were prepared using three calcination temperatures (500, 550 and 600 °C) and using 2-hydroxyethylammonium acetate (2HEAA) and methyl-imidazolium hydrogensulfate ((HMIM)HSO₄) ionic liquids (IL) as solvents for the precursors solutions Both ionic liquids used were characterized in terms of water content and viscosity. The 2HEAA IL is almost 10 times more viscous than the (HMIM)HSO₄ IL. The anodes developed were electrochem. characterized by cyclic voltammetry, morphol. factor, electrochem. impedance spectroscopy and accelerated service lifetime tests. The electrodes synthesized using the 2HEAA IL have superior electrocatalytic properties and electrochem. stability than those made using the (HMIM)HSO₄ IL. In addition, the anodes made using the 2HEAA IL as solvent have more homogenous surfaces and higher crystallinity degree than those made using the (HMIM)HSO₄ IL. Among the studied calcination temperatures, combining 550 °C and the 2HEAA IL results in more compact and rough electrode surfaces with the highest electroactive areas and electrochem. stability. Thus, the temperature of 550 °C is suitable for the synthesis of mixed metal oxide (MMO) anodes. The electrodes synthesized using the 2HEAA IL are more efficient in the electrochem. oxidation of the Reactive Yellow 186 dye than those made using the (HMIM)HSO₄ IL. Consequently, the viscosity of the IL used has great influence on the performance of the synthesized anodes. In addition, the high viscosity of the 2HEAA IL results in a lower number of calcinations steps to produce the anodes and, hence, lower production cost. Viscous ionic liquids are therefore promising for the production of MMO anodes via thermal decomposition methods.

Chronic lymphoblastic leukemia (CLL) is the most common adult leukemia and mainly affects the elderly. Chemoimmunotherapy still has a role in the standard frontline therapy for specific population. However, the clin. activity of bendamustine has not been investigated in unfit Chinese patients with CLL. To compare the efficacy and safety of bendamustine vs. chlorambucil for untreated Chinese patients with Binet stage B/C CLL. Methods. In this multi-center, randomized, open-label, parallel-controlled, phase III trial, patients with previously untreated CLL were enrolled and randomly assigned (1:1) to receive bendamustine or chlorambucil. The primary endpoint was the objective response rate. Secondary endpoints included progression-free survival, the duration of response, and overall survival. Adverse events were recorded to evaluate safety. Of 158 screened patients, 147 were enrolled and randomly allocated to receive bendamustine (n = 72) or chlorambucil (n = 75). After a median follow-up of 25.6 mo (IQR 12.5-27.7), 69.0% (95% CI, 56.9-79.5) of bendamustine-treated patients achieved objective response and 37.0% (95% CI, 26.0-49.1) of chlorambucil with a difference of 32.0% (95%CI: 16.6-47.5), demonstrating the superiority of bendamustine to chlorambucil (p < 0.001). The median progression-free survival was longer for bendamustine (16.5 mo; 95% CI, 11.3-24.7) vs. chlorambucil (9.6 mo; 95% CI, 8.7-11.8; p < 0.001). A longer median duration of response was seen in those receiving bendamustine (19.2 mo; 95% CI, 11.8-29.1) than chlorambucil (10.7 mo; 95% CI, 5.6-13.6; p = 0.0018). Median overall survival was not reached in either group. Overall survival at 18 mo was 88% for bendamustine vs. 85% for chlorambucil. Most common adverse events in both groups were neutropenia and thrombocytopenia. In untreated Chinese patients with Binet stage B/C CLL, bendamustine induced the better objective response and resulted in longer progression-free survival than chlorambucil. Overall, these results validate the role of bendamustine as an effective and safe first-line therapy in this population. This study involved multiple reactions and reactants, such as 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7Recommanded Product: 16506-27-7).
