Although their effectiveness, these drugs may be accompanied by intolerance reactions. When these occur, no codified alternative therapeutic seems to be used to our knowledge. Authors aimed to evaluate the induction of tolerance to NSAIDs as an effective alternative therapeutic. Methods: 22 patients (15 men and 7 women aged from 12 to 39 years with mean age: 22.41 ± 7.88) suffering from vaso-occlusive painful crisis were enrolled. They were known to have a history of sickle cell disease and at least one episode of adverse reactions following the Ibuprofen or Diclofenac intake. A rapid protocol of oral challenge was used in patients to induce tolerance to NSAIDs. The first day, initial doses (8.82 mg for Ibuprofen and 2.20 mg for Diclofenac) were given and gradually increased at intervals of 1 hour over a total period of 6 hours. On the second and third days, the therapeutic dose has been orally administrated with an interval of 6 hours over a period of 12 hours. Results: Despite of some cases of failure that might be related to the severity of symptoms or possible patho-physiological mechanism, more than 80% of patients have successfully tolerated Diclofenac and Ibuprofen. Conclusion: This experience appears to be the first in our context. It might be used as a solution in the lack of alternative therapeutic in the management of vaso-occlusive painful crisis of sickle cell disease as well as in other diseases such as HIV infection where patients often develop intolerance to none alternative antibiotics.展开更多

METHODS： Seventy-one consecutive patients on chronic therapy with NSAIDs were enrolled in the study and divided into groups A and 13 （group A receiving 40 mg pantoprazole daily, group B only receiving NSAIDs）. Sucrose test was performed at baseline and after 2, 4 and 12 wk, respectively. The symptoms in the upper gastrointestinal tract were recorded. RESULTS： The patients treated with pantoprazole had sucrose excretion under the limit during the entire follow-up period. The patients without gastroprotection had sucrose excretion above the limit after 2 wk, with an increasing trend in the following weeks （P = 0.000）. A number of patients in this group revealed a significantly altered gastric permeability although they were asymptomatic during the follow-up period. CONCLUSION： Sucrose test can be proposed as a valid tool for the clinical evaluation of NSAIDs-induced gastric damage in both acute and chronic therapy. This tecnique helps to identify patients with clinically silent gastric damages. Pantoprazole （40 mg daily） is effective and well tolerated in chronic NSAID users .展开更多

To assess tumor angiogenesis, MVD was determined by immunohitochemical staining of endothelial protein factor Ⅷ-related antigen. The relationship among COX-2 and VEGF expression, MVD, and clinicopathologic parameters was analyzed. RESULTS: Among the 67 samples, high MVD was significantly associated with lymph node metastasis and poor survival. Multivariate survival analysis showed that MVD value and lymph node metastasis were independent prognostic factors. The expression rate of COX-2 and VEGF was significantly higher than that of the adjacent tissues. COX-2 and VEGF expression in gastric cancer was significantly correlated with tumor differentiation and depth of invasion, but not with survival. The mean MVD value of COX-2 or VEGF positive tumors was higher than that of COX-2 or VEGF negative tumors. A significant correlation was found between the expressions of COX-2and VEGF. CONCLUSION: MVD may be one of the important prognostic factors for gastric cancer patients. COX-2 and VEGF may play an important role in tumor progression by stimulating angiogenesis. VEGF might play a main role in the COX-2 angiogenic pathway. The inhibition of angiogenesis or COX-2, VEGF activity may have an important therapeutic benefit in the control of gastric cancer.展开更多

文摘Background and Aims: In Ivoirian’s school, the management of vaso-occlusive painful crisis in sickle cell disease requires non steroidal anti inflammatory drugs (NSAIDs). Although their effectiveness, these drugs may be accompanied by intolerance reactions. When these occur, no codified alternative therapeutic seems to be used to our knowledge. Authors aimed to evaluate the induction of tolerance to NSAIDs as an effective alternative therapeutic. Methods: 22 patients (15 men and 7 women aged from 12 to 39 years with mean age: 22.41 ± 7.88) suffering from vaso-occlusive painful crisis were enrolled. They were known to have a history of sickle cell disease and at least one episode of adverse reactions following the Ibuprofen or Diclofenac intake. A rapid protocol of oral challenge was used in patients to induce tolerance to NSAIDs. The first day, initial doses (8.82 mg for Ibuprofen and 2.20 mg for Diclofenac) were given and gradually increased at intervals of 1 hour over a total period of 6 hours.

文摘AIM: To investigate whether microvessel density (MVD) is related with prognosis in gastric cancer patients, and the expression of cyclooxygenase-2 (COX-2) and vessel endothelial growth factor (VEGF) so as to determine the possible role of COX-2 and VEGF in gastric cancer angiogenesis.METHODS: Forty-seven formalin-fixed paraffin-embedded tissue samples of gastric cancer were evaluated for COX-2, VEGF by immunohitochemical staining. To assess tumor angiogenesis, MVD was determined by immunohitochemical staining of endothelial protein factor Ⅷ-related antigen. The relationship among COX-2 and VEGF expression, MVD, and clinicopathologic parameters was analyzed. RESULTS: Among the 67 samples, high MVD was significantly associated with lymph node metastasis and poor survival. Multivariate survival analysis showed that MVD value and lymph node metastasis were independent prognostic factors. The expression rate of COX-2 and VEGF was significantly higher than that of the adjacent tissues. COX-2 and VEGF expression in gastric cancer was significantly correlated with tumor differentiation and depth of invasion, but not with survival. The mean MVD value of COX-2 or VEGF positive tumors was higher than that of COX-2 or VEGF negative tumors. A significant correlation was found between the expressions of COX-2and VEGF. CONCLUSION: MVD may be one of the important prognostic factors for gastric cancer patients. COX-2 and VEGF may play an important role in tumor progression by stimulating angiogenesis. VEGF might play a main role in the COX-2 angiogenic pathway. The inhibition of angiogenesis or COX-2, VEGF activity may have an important therapeutic benefit in the control of gastric cancer.

文摘OBJECTIVE To isolate and characterize bioactive compound from traditionally important medicinal plant Mikania cordata,and to investigate muti-faced pharmacological activities of the isolated compound.METHODS A triterpeenoid,16-hydroxy betulinic acid(16 HBA) was isolated from Mikania cordata leaf and the structure of the compound was determined by NMR spectroscopic means.Antimicrobial activity of 16 HBA was tested by disc diffusion method and minimum inhibitory concentration(MIC) against the tested microorganisms was determined.The analgesic property of 16 HBA was tested using acetic acid-induced writhes in mice and hot plate thermal stimulation in rats.The anti-inflammatory activity was studied using carrageenin-induced paw edema method.The antipyretic potential of 16 HBA was evaluated by using yeast-induced hyperthermia in rats.RESULTS The triterpenoid 16 HBA showed potent antibacterial activity with inhibition zone of diameter ranging from 12.0~17.5 mm and antifungal activity with mycelial growth inhibition ranges from 37.6%~54.5%.The MIC values for antibacterial and antifungal activities ranged from 31.5~125 and 250~1000 μg·mL-1 respectively.The compound(50 and100 mg·kg^(-1) body weight) showed potent peripheral and central analgesic activity having 55.19% and41% of writhing inhibition at 90 min after administration of the compound and the highest 55.98%,79.18% elongation of reaction time,respectively.In anti-inflammatory activity screening,the compound(100 mg·kg^(-1)) revealed the highest 77.08% edema inhibition at 4 h after administration of carrageenan.In antipyretic assay,16 HBA exhibited a strong antipyretic effect in yeast-induced rats.CONCLUSION The present study confirmed that 16-hydroxy betulinic acid isolated from Mikania cordata has potent antimicrobial,analgesic,anti-inflammatory and antipyretic properties.Our results can be seen as scientific support for the traditional and folklore usage of Mikania cordata in Bangladesh for the treatment of different ailments and provide opportunities to explore this plant as a source bioactive compounds for biochemical and pharmaceutical industries.
文摘Two new complexes (Cp) 2Ti(Cin) 2 and (Cp) 2Ti(Tzea) 2 (Cp= Cyclopentadienyl η 5 C 5H 5) have been synthesized in THF by the reaction of HCin (Cincofen, 2 phenylquinoline 4 carboxylic acid) or HTzea (5 phenyltetrazolyl 2 ethanoic acid) with (Cp) 2TiCl 2, and characterized by elemental analyses, IR, 1H NMR and 13 C NMR, UV spectra, molar conductivity, TG DTA. In the complexes the carboxyl groups are coordinated to Ti(IV) in a monodentate manner. The inhibitory actions of the complexes on mice ear tumefaction caused by croton oil and the rat foot granulation growth produced by cotton wool are higher than those of the corresponding ligands HCin, HTzea and [(Cp) 2TiCl 2], while their toxicities are lower than those of the free ligands.
文摘Aim:This study was conducted to determine the preferred analgesic and anti-inflammatory drugs prescribed by oral implantologists in India.Methods:A structured questionnaire was distributed to 332 dentists to gather information regarding their prescription habits for analgesics and anti-inflammatory drugs.Frequency distributions were computed by type of drug being prescribed and the protocol followed.Results:Analysis of data showed that majority of dentists(85.8%,n=285)prescribed conventional non-steroidal anti-inflammatory drugs(NSAIDs)for implant surgery.The most common prescription was ibuprofen with paracetamol combination(32.2%,n=107)followed by diclofenac(20.2%,n=67).Most dentists reported prescribing different NSAIDs for the same procedure in different patients(64.7%,n=215).Only,35.5%(n=118)followed the peri-operative protocol.Adjunctive prescription of steroids was done by only 33.7%(n=112).Conclusion:Our study illustrates that the general trend of analgesic and anti-inflammatory drug prescription for dental implant surgery among Indian dentists is mostly in accordance with the guidelines for pain management worldwide.However,it is noteworthy that a few dentists do prescribe drugs not primarily indicated for dental pain management and use widely varying protocols for the same.Therefore,in order to avoid potential complications,it is essential to raise awareness of among the dental practitioners of the appropriate indications and dosage regimen of specific drugs.

文摘To the Editor:After chimeric antigen receptor T(CAR-T)cell therapy,over 90%of patients experience either mild or severe cytopenia,with the prevalence of Grades 3–4 neutropenia ranging from 53%to 94.3%.[1,2]Granulocyte colony-stimulating factor(G-CSF),known for its ability to enhance the proliferation and differentiation of neutrophils,has been extensively employed for the prevention and treatment of neutropenia in various contexts.However,its application in patients with refractory/relapsing B-cell acute lymphoblastic leukemia(R/R B-ALL)after CAR-T cell therapy remains a topic of debate.[3]Several studies have suggested that G-CSF may exert anti-inflammatory effects by modulating the release of inflammatory factors,such as interleukin-12(IL-12),TNF-α,and IFN-γ,or by influencing the differentiation of T-cell subsets.[4]However,other researchers have posited that G-CSF could exacerbate cytokine release syndrome(CRS)and immune effector cell-associated neurotoxicity syndrome(ICANS)through the augmentation of antigen-presenting cell function.

文摘Neuroinflammation has been proposed as a strong biological factor underlying the development of neuropsychiatric diseases.A role for dysregulation of the immune system was initially suggested in depressive disorders and subsequently extended to other illnesses,including bipolar disorder(BD).Indeed,there is growing evidence confirming the presence of a generalized pro-inflammatory state in BD patients,involving alterations in cytokine,acute-phase proteins,and complement factor secretion,white blood cell differentiation,microglial activation,arachidonic acid signaling pathways,and increased oxidative stress markers.Medications commonly used to treat BD,such as lithium,antiepileptics and antipsychotics,show some immunoregulatory activity both in vitro and in vivo.The aim of our study was to review the role of different inflammatory mechanisms,specifically in the development of excitatory symptoms,via a systematic PubMed search of the literature.Despite the high variability of results among studies,we found evidence indicating specific alterations of the inflammatory response during manic and mixed states of BD.These findings may help to clarify some of the complex mechanisms underlying the development of excitatory symptoms and suggest a potential role for drugs targeting the inflammatory system as new therapeutic options.
