Allulose mitigates chronic enteritis by reducing mitochondria dysfunction via regulating cathepsin B production.

Metabolic changes have been linked to the development of inflammatory bowel disease (IBD), which includes colitis. Allulose, an endogenous bioactive monosaccharide, is vital to the synthesis of numerous compounds and metabolic processes within living organisms. Nevertheless, the precise biochemical mechanism by which allulose inhibits colitis remains unknown. Allulose is an essential and intrinsic protector of the intestinal mucosal barrier, as it maintains the integrity of tight junctions in the intestines, according to the current research. It is also important to know that there is a link between the severity of inflammatory bowel disease (IBD) and colorectal cancer (CRC), chemically-induced colitis in rodents, and lower levels of allulose in the blood. Mice with colitis, either caused by dextran sodium sulphate (DSS) or naturally occurring colitis in IL-10-/- mice, had less damage to their intestinal mucosa after being given allulose. Giving allulose to a colitis model starts a chain of reactions because it stops cathepsin B from ejecting and helps lysosomes stick together. This system effectively stops the activity of myosin light chain kinase (MLCK) when intestinal epithelial damage happens. This stops the breakdown of tight junction integrity and the start of mitochondrial dysfunction. To summarise, the study's findings have presented data that supports the advantageous impact of allulose in reducing the advancement of colitis. Its ability to stop the disruption of the intestinal barrier enables this. Therefore, allulose has potential as a medicinal supplement for treating colitis.

The Clinical Research of Serum VEGF, TGF-ß1, and Endostatin in Non-small Cell Lung Cancer.

The aim of the study was to analyze the expressions of vascular endothelial growth factor (VEGF), transforming growth factor ß1 (TGF-ß1) and endostatin in non-small cell lung caner (NSCLC), and to explore their correlations with NSCLC. 80 NSCLC patients during January 2013 to June 2014 were selected. The expression levels of VEGF, TGF-ß1, and endostatin before surgeries were detected, and compared with 40 healthy individuals and 40 patients with benign pulmonary diseases. Serum VEGF, TGF-ß1, and endostatin levels were (573.6 ± 25.4) pg/mL, (36.2 ± 10.5) ng/mL, and (20.3 ± 7.8) ng/mL, respectively, in NSCLC group, which were obviously higher than those in healthy individuals and patients with benign pulmonary diseases, and the difference was statistically significant (p < 0.05); there was no statistical difference of the VEGF, TGF-ß1, and endostatin levels between the healthy individuals and patients with benign pulmonary diseases (p > 0.05), or among patients with different physiological characteristics such as gender, age, and smoking history in NSCLC group (p > 0.05). Serum VEGF, TGF-ß1, and endostatin levels also showed no statistical difference among patients with different pathological characteristics such as histological types, with or without lymphatic metastasis (p > 0.05). However, the three indicators were significantly different among patients with different TNM stages, with or without distant metastasis and different cell differentiation degrees (p < 0.05). Serum VEGF and TGF-ß1 were positively related (r = 0.479, p < 0.05), endostatin was negatively related to both VEGF and TGF-ß1 (r = -0.392, -0.354, p < 0.05 in both comparisons). The expression levels of VEGF, TGF-ß1, and endostatin significantly contributed to the poor cell differentiation in NSCLC. They had important effects on the occurrence, development, and metastasis of NSCLC, which could be applied as the indicators to predict the malignancy of NSCLC.

Primary bone lymphoma: A case report and review of the literature.

Primary lymphoma of the bone (PLB) primarily arising from the medullary cavity is an extremely rare entity, with only retrospective studies and sporadic cases reported in the literature. The current study presents one case of PLB treated with chemotherapy and radiotherapy, and a review of the literature to elucidate the optimal treatment of PLB. A 73-year-old female presented with pain in the left hip that had persisted for two months. Plain X-ray and magnetic resonance imaging of the left hip showed lytic areas involving the left innominatum. Technetium-99m radionuclide imaging showed increased tracer uptake in the ilium, acetabulum and ischium. An 18F-fluorodeoxyglucose-positron emission tomography-computed tomography (FDG-PET-CT) scan showed high FDG uptake. A fine-needle aspiration biopsy of the lesion was performed, and histopathological and immunohistochemical examination confirmed a diagnosis of B-cell lymphoma. The patient received radiation therapy followed by six cycles of CHOP regimen (1,000 mg cyclophosphamide, 80 mg epirubicine and 2 mg vincristine on day one, and 100 mg prednisone on days one to five, every three weeks) and achieved a complete response, as confirmed by FDG-PET-CT. At present, the patient is in a good condition. This case is noteworthy, as it is a well-documented case in which the patient received successful treatment. This case demonstrates that PLB has an improved prognosis compared with primary lymphoma of other sites; however, combined therapy may further improve the patient outcome.

The programmed cell death 6 interacting protein insertion/deletion polymorphism is associated with non-small cell lung cancer risk in a Chinese Han population.

It has been proposed that genetic factors contribute to the susceptibility of non-small cell lung cancer (NSCLC). The programmed cell death 6 interacting protein (PDCD6IP) encodes for a protein that has been known to bind to the products of the PDCD6 gene, a required protein in apoptosis. The aim of this study is to investigate the relationship between PDCD6IP insertion/deletion (I/D) polymorphism (rs28381975) and NSCLC risk in a Chinese population. A population-based case-control study was conducted in 449 NSCLC patients and 512 cancer-free controls. The genotype of the PDCD6IP gene was determined by using a polymerase chain reaction assay. The promoter activity was analyzed by luciferase reporter assay in A549 and H1299 cells. Statistically significant difference was observed when the patients and controls were compared according to ID + II versus DD (OR = 1.72, 95 % CI 1.29-2.31, P < 0.01). The I allele was significantly associated with NSCLC risk (OR = 1.41, 95 % CI 1.18-1.69, P < 0.01). Compared to TNM stage I + II, PDCD6IP I/D polymorphism significantly increased advanced NSCLC risk (OR = 2.06, 95 % CI 1.30-3.26, P < 0.01). Promoter reporter structures carrying the I allele displayed significantly higher promoter activity than the D allele in A549 and H1299 cells (P = 0.001). The results from this study suggested that PDCD6IP I/D polymorphism was potentially related to NSCLC susceptibility in Chinese Han population.

Association of chemotherapy-induced leucopenia with treatment outcomes in advanced non-small-cell lung cancer cases receiving the NP regimen.

BACKGROUND: Chemotherapy induced leutropenia has been shown to be associated with improved treatment outcomes in selected solid tumors. We studied the association of chemotherapy induced leutropenia with treatment related outcomes in advanced non-small-cell lung cancer. METHODS: This is a prospective analysis of patients receiving chemotherapy for advanced NSCLC at the Shandong Cancer Hospital from 2005-07.The chemotherapy included cisplatin 35 mg/m2, IV on d1,2 and vinorelbine 25 mg/m2 IV on d1,8 every 21 days. Patients were stratified into three groups (A) those experiencing grades 0 leucopenia, group (B) grades 1-2 and group (C) grades 3-4. The outcomes studied were response rate (RR), disease control rate (DCR), and time to progression (TTP). RESULTS: 128 patients were studied. The RRs in groups A, B and C were 30.8%, 56.8% and 71.4%, respectively, p=0.010. The DCRs were 61.5%, 83.8% and 92.9%, respectively, p=0.009 and the median TTPs were 150 days (95%CI: 91-209), 189 days (95%CI: 181-197) and 207 days (95%CI: 172-242), p=0.009. The differences in RR and TTP were significant. In patients whose CIL kept on 10 days at least, the TTP was significantly prolonged, p=0.0213, and the same was the case for those experiencing grades 1-2 leucopenia and ECOG 0, p=0.0412. CONCLUSIONS: Occurrence of CIL correlated with RR and TTP in patients with advanced NSCLC receiving cisplatin and vinorelbine chemotherapy, especially in patients experiencing grades 1-2 leucopenia and ECOG 0, and the same for those with CIL persisting for 10 days at least. CIL could be a biological measure of drug activity and a marker of efficacy.
