Background: Thyrosin kinase inhibitors (TKIs) is approved for the first line treatment of non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutation. This study performed to assess clinical effectiveness and safety of Erlova (generic form of Erlotinib). Methods: Somatic mutations of EGFR gene were studied in tumor tissue by polymerase chain reaction (PCR) and bi-directional sequencing in 513 chemonaive and histologically verified lung adenocarcinoma Iranian patients. Patients with EGFR mutation received Erlova at 150 mg/day as first line treatment. Primary endpoint was progression free survival (PFS). Results: About 21% (n=109) cases had EGFR mutation. Most EGFR mutations were occurred at exon 19. Among them, sixty nine patients treated with Erlova. Median PFS was 11.4 months and objective response rate (ORR) was about 88%. Most frequent treatment related adverse events was skin rash. Conclusion: Our findings showed Erlova had remarkable effectiveness. In mutation-positive patients with EGFR, Erlova can be used safely instead of other tyrosine-kinase inhibitors. 相似文献

Helicobacter pylori has grown to colonize inside the stomach of nearly half of the world’s population, turning into the most prevalent infections in the universe. Medical care failures noticeably confirm the need for a vaccine to hinder or deal with H. pylori. This review is planned to discuss the most known factors as a vaccine candidate, including single (AhpC, BG, CagA, KatA, Fla, Hsp, HWC, Lpp, LPS, NAP, OMP, OMV, SOD, Tpx, Urease, VacA) and multi-component vaccines. Many promising results in the field of single and multivalent vaccine can be seen, but there is no satisfactory outcome and neither a prophylactic nor a therapeutic vaccine to treat or eradicate the infection in human has been acquired. Hence, selecting suitable antigen is an important factor as an appropriate adjuvant. Taken all together, the development of efficient anti-H. pylori vaccines relies on the fully understanding of the interactions between H. pylori and its host immune system. Therefore, more work should be done on epitope mapping, analysis of molecular structure, and determination of the antigen determinant region as well due to design a vaccine, preferably a multi-component vaccine to elicit specific CD4 T-cell responses that are required for H. pylori vaccine efficacy. 相似文献

Objectives:
Sympathetic skin response (SSR) is a test for evaluation of the sympathetic sweat gland pathways, and it has been used to study the central sympathetic pathways in spinal cord injury (SCI). This study aimed to assess the autonomic pathways according to normal or abnormal SSR in urinary incontinence patients due to incomplete spinal cord injury.Materials and Methods:
Suprapubic, palmar, and plantar SSR to the peripheral nerve electrical stimulation were recorded in 16 urinary incontinence patients with incomplete spinal cord injury at various neurological levels and in 30 healthy control subjects.Results:
All the recordings of SSR from the incomplete SCI patients with urinary incontinence as compared with their counterparts in the control group showed significantly reduced amplitudes with more prominent reduction in the suprapubic area recording site (P value < 0.0004). SSR with significantly prolonged latencies were recorded from palm and plantar areas in response to suprapubic area and tibial N stimuli, respectively (P value < 0.02). In this study, a significantly higher stimulus intensity (P value < 0.01) was needed to elicit SSR in the cases compared with the control group.Conclusion:
This study showed abnormal SSR in urinary incontinence patients due to incomplete SCI. In addition, for the first time we have described recording of abnormal SSR from the suprapubic area as another way to show bladder sympathetic system involvement. 相似文献4.

Myeloproliferation, myelofibrosis, and neoangiogenesis are the 3 major intrinsic pathophysiologic features of myeloid metaplasia with myelofibrosis (MMM). The myeloproliferation is characterized by an increased number of circulating CD34+ progenitors with the prominent amplification of dystrophic megakaryocytic (MK) cells and myeloid metaplasia in the spleen and liver. The various biologic activities of interleukin 8 (IL-8) in hematopoietic progenitor proliferation and mobilization as well as in neoangiogenesis prompted us to analyze its potential role in MMM. We showed that the level of IL-8 chemokine is significantly increased in the serum of patients and that various hematopoietic cells, including platelets, participate in its production. In vitro inhibition of autocrine IL-8 expressed by CD34+ cells with either a neutralizing or an antisense anti-IL-8 treatment increases the proliferation of MMM CD34(+)-derived cells and stimulates their MK differentiation. Moreover, addition of neutralizing anti-IL-8 receptor (CXC chemokine receptor 1 [CXCR1] or 2 [CXCR2]) antibodies to MMM CD34+ cells cultured under MK liquid culture conditions increases the proliferation and differentiation of MMM CD41+ MK cells and restores their polyploidization. Our results suggest that IL-8 and its receptors participate in the altered MK growth that features MMM and open new therapeutic prospects for this still incurable disease. 相似文献

BACKGROUND: Neuropeptide Y is a sympathetic neurotransmitter, a potent endothelium‐derived angiogenic factor and a vascular mitogen. We have studied the role of the functional leucine7 to proline7 polymorphism of the signal peptide region of preproneuropeptide Y (prepro‐NPY) as a genetic susceptibility factor for diabetic retinopathy. In addition, we investigated the role of the NPY Y2‐receptor as a putative mediator of angiogenic NPY signaling in the retina. METHODS: Frequencies of proline7 (Pro7) carriers in the prepro‐NPY were determined in type 1 and type 2 diabetes patients having retinopathy, in type 2 diabetes patients without retinopathy and in healthy control subjects. The role of Y2‐receptor in hyperoxemia‐induced retinal neovascularization was investigated in Y2‐receptor knockout mice (Y2 ?/? ) and in rats administered Y2‐receptor mRNA antisense oligonucleotide. RESULTS: The carriers having Pro7 in the preproNPY are markedly over‐represented among type 2 diabetes patients with retinopathy compared to type 2 diabetes patients without retinopathy and to the population control. Neonatal exposure to hyperoxia resulted in development of retinal neovascularization that was prevented in Y2 ?/? ‐mice, and significantly inhibited in rats treated with the Y2‐receptor antisense oligonucleotide. CONCLUSIONS: NPY and Y2‐receptor play important roles in diabetic retinopathy and retinal neovascularization and are thus potential new targets for drug molecules for treatment of retinopathy. 相似文献

Temporal lobe epilepsy (TLE) is a rather common and difficult-to-treat variant of epilepsy. Nearly one third of people with epilepsy do not respond effectively to currently available anticonvulsants. In this study, we evaluated the protective effect of thymoquinone (TQ), the main constituent of black seed with antioxidant and anti-inflammatory effects, in the intrahippocampal kainate model of TLE in rat. Following kainate injection, seizure activity was observed that was significantly diminished by TQ pretreatment at a dose of 10 mg/kg, p.o. Intrahippocampal kainate also increased malondialdehyde (MDA), nitrite, and nitrate levels and decreased activity of superoxide dismutase and TQ only significantly attenuated MDA. In addition, intrahippocampal kainate caused a significant reduction of neurons in CA1, CA3 and the hilar regions, and TQ significantly attenuated these changes. Timm histochemistry showed a marked mossy fiber sprouting (MFS) in the dentate gyrus of kainate-lesioned rats, and TQ significantly lowered MFS intensity. Meanwhile, a number of reactive astrocytes (astrogliosis) increased significantly in the kainate group, and TQ pretreatment significantly decreased it. These data suggest that TQ pretreatment could attenuate seizure activity and lipid peroxidation, lower hippocampal neuronal loss and MFS, and mitigate astrogliosis in kainate model of TLE. 相似文献

PurposeOxidative damage has been implicated in carcinogenesis. We hypothesized that elevated systemic oxidative status would be associated with later occurrence of colorectal adenomatous polyps, a precursor of colorectal cancer.MethodsWe examined the prospective association between four systemic markers of oxidative status and colorectal adenomatous polyps within a nondiabetic subcohort of the Insulin Resistance Atherosclerosis Study (n = 425). Urine samples were collected from 1992 to 1994 and colorectal adenomas prevalence were assessed in 2002 to 2004. Oxidative status markers were assessed, which included four F2-isoprostanes (F2-IsoPs) from the classes III and IV: iPF2α-III, 2,3-dinor-iPF2α-III (a metabolite of iPF2α-III), iPF2α-VI, and 8,12-iso-iPF2α-VI. All biomarkers were quantified using liquid chromatography–tandem mass spectrometry. Prospective associations were assessed using multivariate logistic regression analysis.ResultsThe adjusted odds ratio (OR) (95% confidence interval [CI]) for occurrence of colorectal adenomatous polyps and scaled to 1 SD of F2-IsoP distribution were 1.16 (95% CI, 0.88–1.50), 0.88 (95% CI, 0.63–1.17), 1.04 (95% CI, 0.80–1.34), and 1.16 (95% CI, 0.90–1.48) for iPF2α-III, iPF2α-VI, 8,12-iso-iPF2α-VI, and 2,3-dinor-iPF2α-III, respectively.ConclusionsThe lack of association between F2-IsoPs and adenomatous polyps does not support the hypothesis that elevated oxidative status is associated with colorectal adenomatous polyp occurrence during a 10-year period of follow-up. 相似文献

In this study our aim was to explore the experiences of doula support among foreign-born women in Sweden in the context of a "Community-Based Doula" (CBD) intervention project. We conducted interviews with 10 women and analyzed the data using content analysis. Participating women reported that, in addition to support during labor, doulas provided important information and continuity of care, which apparently increased their satisfaction with and trust in maternity health care. Training of CBDs, therefore, has implications for the delivery of equitable maternity care, which applies not only to Sweden and other European countries but wherever there are increasingly diverse populations. 相似文献
