Redirecting T cells by transferring T cell receptor (TCR) genes from tumor-associated antigen (TAA)-reactive T cell clones into human peripheral blood lymphocytes (PBL) has therapeutic potential for the treatment of diseases, including cancer. T cell specificity can be altered using retroviruses encoding TCR f and TCR g chain genes, or chimeric immunoglobulin (cIg) genes containing signaling domains of CD3 ‘ or Fc l RI- n. This review evaluates recent studies using TCRs and cIgs to redirect T cell specificity and discusses some of the technical and biological hurdles that need to be addressed before these approaches can be successfully used to treat patients. 相似文献

Cervical spondylolysis is a rare condition defined as a corticated cleft at the pars interarticularis in the cervical spine. This is the case of C2 spondylolysis demonstrating progressive significant instability, which was successfully treated by anterior cervical discectomy and fusion (ACDF) with cervical anterior plate. We describe a 20-year-old female with C2 spondylolysis presenting with progressive worsening of neck pain associated with progressive instability at the C2/3 segment. The progression of instability was well-documented on flexion-extension cervical spine x-rays. She was successfully treated by C2/3 ACDF with anterior cervical plate. Her preoperative significant neck pain resolved immediately after the surgical intervention. She was completely free from neurological symptoms at 1-year postoperative follow-up. We also review the literature and discuss 24 reported cases with C2 spondylolysis. When planning treatment, we should make sure to differentiate this pathology from acute traumatic fracture, which is a hangman''s fracture. Assessment of C2/3 instability associated with neurological deficits is extremely important to consider management properly. C2/3 ACDF with cervical plate is biomechanically viable, less invasive, and provides adequate surgical stabilization for unstable C2 spondylolysis. 相似文献

While endovascular coil embolization has become one of the major therapeutic modalities for intracranial aneurysms, long-term imaging follow-up is required because of the higher rate of retreatment compared with surgical clipping. The purpose of this study was to show the usefulness of craniograms to discriminate coiled intracranial aneurysms that required retreatment. Under the study protocol approved by institutional review board, a retrospective review of the medical record was done regarding coil embolization for intracranial aneurysms performed between January 2014 and December 2018. Coil embolization performed as the initial treatment and followed up for more than 1 year without additional treatment, and those performed as retreatment after the initial coil embolization performed at our institution were recruited. Craniograms obtained just after the initial treatment were compared with those obtained just before the additional treatment in the retreated cases and compared with the latest ones in the non-recurrence cases. Correlation between the morphological changes in the coil mass on the craniograms and retreatments was evaluated. During the study period, 288 coil embolization procedures for intracranial aneurysms were performed. From these, 191 treatments that were followed up for more than 1 year without any additional treatments and 30 retreatments were included. Morphological change of the coil mass was observed in 4 of the 191 non-recurrence treatments and 26 of the 30 retreatments, which was significantly correlated with retreatments (p <0.001). Craniogram was a useful modality in following up the coiled intracranial aneurysms to detect those required retreatments. 相似文献

We encountered an 8 year old boy who suffered from Stevens-Johnson syndrome with Mycoplasma pneumoniae infection. He had multiple erythema with vesicles in oral mucosa, and on his palms and feet, trunk and genital regions. We treated him with prednisolone (1 mg/kg per day) and antibiotics. His skin lesions improved dramatically, and a persistent fever and toxic general condition also showed dramatic improvement. Although the use of corticosteroids for Stevens-Johnson syndrome has recently been controversial, we thought that administration of corticosteroids was an effective treatment for some selective cases of Stevens-Johnson syndrome. The patient reported in this study had many beneficial effects in response to corticosteroid treatment. 相似文献

Two girls with acute lymphocytic leukemia (ALL) are reported. There were difficulties in removing their central venous catheters inserted from a peripheral vein. One girl required surgery under general anesthesia for the removal. The other patient received continuous infusion of low dose urokinase from a distal peripheral vein. The residual catheter was then removed successfully. 相似文献

Two autopsy cases of Cronkhite-Canada syndrome were reported. The caused of hypoproteinemia, electrolyte imbalance and ectodermal changes were discussed with reference to previously reported cases. The mechanism of protein loss was probably due to outflow into the intestinal lumen of the mucous substance in the cystically dilated glands, directly and/or indirectly followed by loss of mucosal surface. Electrolyte imbalance probably developed from gastrointestinal loss as well as poor substitution. The ectodermal changes were probably not a subsequent part of the emaciation or hypoproteinemis, but an inherent part of this disease. Therapy, whether substitution or surgical procedure, should be selected in order to control the general condition of the patient. 相似文献

BACKGROUND: We report here an extremely rare case of cystosarcoma phyllodes of the seminal vesicle. METHODS: A 65-year-old man presented with urinary hesitancy, frequency and constipation. Clinical examinations including two needle biopsies were performed, and the patient had undergone open surgery. RESULTS: The final pathological diagnosis was cystosarcoma phyllodes of the seminal vesicle. Seven months after the operation, a chest X-ray showed lung metastasis, and the patient died 11 months after the operation. CONCLUSION: To our knowledge, only one case of cystosarcoma phyllodes of the seminal vesicle has been previously reported. 相似文献

Utility of immunohistochemical detection of prostate-specific Ets for the diagnosis of benign and malignant prostatic epithelial lesions 总被引:4,自引:0,他引:4

BACKGROUND: Human prostate-specific Ets (hPSE) belongs to the Ets family. It regulates the proliferation, differentiation, and development of prostate epithelial cells. A recent study showed that hPSE can be detected in normal glands but not in cell lines established from prostate cancer (PCA), suggesting a translational disorder of hPSE from mRNA to protein in PCA. Immunohistochemical detection of hPSE could therefore be another method of differential diagnosis of PCA from other proliferative conditions in the prostate. METHODS: An immunohistochemical detection of hPSE was carried out on the whole mounted prostatectomy specimen obtained from 19 cases with PCA. RESULTS: Basal and secretory luminar cells showed a diffuse cytoplasmic staining for hPSE in normal glands, hyperplastic glands, and prostate intraepithelial neoplasia lesions. Whereas approximately 30% of PCA lesions showed a negative staining for hPSE, the positive rate for hPSE between PCA and benign glands or prostate intraepithelial neoplasia (PIN), was statistically significant (P < 0.05). Staining intensities in normal glands, hyperplastic glands, and PIN lesions were similar, but generally stronger than those in PCA lesions. CONCLUSIONS: Negative immunoreactivity for hPSE strongly suggests malignancy in the prostate glands. Decreased immunoreactivities of glands for hPSE could suggest PCA. 相似文献

Summary. We have studied two heterozygous unrelated CRM non-Jewish FXI-deficient patients. Neither of the patients carries a previously described mutation. Their FXI genes were screened by SSCP analysis following PCR amplification of each exon and the flanking intronic sequences. DNA fragments showing aberrant mobility were cloned and sequenced. The following mutations were identified: in case 1, a T to G transition in exon 12 results in the substitution of Phe-442 by Val (FXI-F442V); in case 2 a C to A transition in exon 5 results in the substitution of Cys-128 by a nonsense codon (FXI-C128X). The missense mutation results in a substitution within the protease domain of FXI. Molecular modelling locates this residue in a structurally conserved region of the protease domain and the amino acid substitution may therefore interfere with either chain folding and subsequent secretion or the stability of the protein in plasma. We conclude that the mutations which we have identified are responsible for the inherited abnormality in these patients. 相似文献

Background: High-frequency oscillation ventilation (HFOV) is an accepted ventilatory mode for acute respiratory failure in neonates. As conventional mechanical ventilation, inspiratory gas humidification is essential. However, humidification during HFOV has not been clarified. In this bench study, we evaluated humidification during HFOV in the open circumstance of ICU. Our hypothesis is that humidification during HFOV is affected by circuit design and ventilatory settings.
Methods/Materials: We connected a ventilator with HFOV mode to a neonatal lung model that was placed in an infant incubator set at 37°C. We set a heated humidifier (Fisher & Paykel) to obtain 37°C at the chamber outlet and 40°C at the distal temperature probe. We measured absolute humidity and temperature at the Y-piece using a rapid-response hygrometer. We evaluated two types of ventilator circuit: a circuit with inner heating wire and another with embedded heating element. In addition, we evaluated three lengths of the inspiratory limb, three stroke volumes, three frequencies, and three mean airway pressures.
Results: The circuit with embedded heating element provided significantly higher absolute humidity and temperature than one with inner heating wire. As an extended tube lacking a heating wire was shorter, absolute humidity and temperature became higher. In the circuit with inner heating wire, absolute humidity and temperature increased as stroke volume increased.
Conclusion: Humidification during HFOV is affected by circuit design and ventilatory settings. 相似文献
