Prostate cancer is the most common cancer and the second leading cause of cancer-related death in American men. To investigate the possible usefulness of tissue inhibitor of metalloproteinase-3 (TIMP-3) in prostate cancer gene therapy, we used an adenovirus expressing TIMP-3 to assess its role as an apoptosis trigger in highly metastatic prostate cancer cell lines PC-3 and DU-145. We showed that TIMP-3 alone induced apoptotic cell death which was triggered by mitochondrion-mediated caspase-3 activation. In combination treatment, we found that adenovirus-mediated expression of TIMP-3 greatly sensitised prostate cancer cells to chemotherapeutic drug paclitaxel, indicating a superadditive or synergistic effect of TIMP-3 and cytostatic treatment on prostate cancer cell death. The proper combination of adenovirus-mediated expression of TIMP-3 with conventional chemotherapeutic drug(s) could have potential benefits in treating highly metastatic prostate cancer. 相似文献

PURPOSE: To demonstrate spectroscopic retinal oximetry measurements on arteries and veins in swine using intravitreal illumination. Retinal arterial and venous saturations are measured for a range of inspired O2 levels after pars plana vitrectomy. METHODS: Pars plana vitrectomy and intravitreal manipulations were performed on two female American Yorkshire domestic swine. Light from a scanning monochromator was coupled into a fiberoptic intraocular illuminator inserted into the vitreous. The retinal vessels were illuminated obliquely, minimizing vessel glints. Multispectral images of the retinal vasculature were obtained as the swine's arterial blood oxygen saturation was decreased from 100% to 67% in decrements of approximately 10%. Retinal vessel spectra were used to calculate oxygen saturation in selected arteries and veins. Arterial oxygen saturations were calibrated using blood gas analysis on blood drawn from a Swan-Ganz catheter placed in the femoral artery. RESULTS: Oblique illumination of retinal vessels using an intravitreal fiberoptic illuminator provided a substantial reduction in the central vessel glint usually seen in fundus images, thus simplifying the analysis of spectral data. The vessel shadows were displaced from the vessel image simplifying the light paths in the eye. Using a full spectral analysis simplified by the light path reductions, we calculated retinal vessel saturations. The reduction of glint allowed for increased accuracy in measuring retinal vessel spectral optical density. Abnormally low retinal venous oxygen saturations were observed shortly after pars plana vitrectomy. CONCLUSIONS: Retinal oximetry using intravitreal illumination has been demonstrated. As a research tool, intravitreal illumination addresses several difficulties encountered when performing retinal oximetry with transcorneal illumination. 相似文献

Aluminium phosphide ingestion is a major cause of poisoning-related mortality in tropical countries. Local oesophageal complications due to aluminium phosphide have been reported to occur rarely. We describe 3 patients who survived the intake of aluminium phosphide tablets and developed oesophageal strictures. 相似文献

The objectives of the study were to determine the nutrient intakes and to examine body image perceptions and weight concerns of elite female US international synchronized skaters. One hundred and twenty-three skaters (mean age = 17.0 +/- 2.1 y; BMI = 21.32 +/- 2.13) representing six US international synchronized skating teams from the 1998 competitive season participated in the study. Nutrient intakes were determined from 3-d dietary records. Body image perceptions were assessed from responses to silhouette drawings. Skaters completed an emotional and physical self-appraisal. Weight concerns were assessed using a self-administered validated weight history questionnaire. The reported energy intake was 26 kcal/kg. The contribution of carbohydrate, fat, and protein to total energy intake was 62%, 23%, and 15% for younger (14-18 y) and 62%, 24%, and 14%, respectively, for the older (19-30 y))skaters. Significant differences (P < 0.001) were observed between perceived ideal and current body shapes. The greater the dissatisfaction with physical and emotional self, the larger the discrepancy between current versus desired body shape. Results suggest that sports nutritionists should not only assess nutrition factors but also examine psychosocial and emotional correlates related to body image and weight concerns of synchronized skaters. 相似文献

Pancreaticopleural fistulas are a rare complication of pancreatitis. We report two cases from our institution and review 37
cases of pancreaticopleural fistulas identified in the literature. Endoscopic retrograde cholangiopancreatography was more
sensitive compared to computed tomography in demonstrating pancreaticopleural fistulas (79% versus 43%, respectively). Medical
therapy with total parenteral nutrition, octreotide, and/or chest tube placement was successful in resolving the pancreaticopleural
fistula in up to 33% of cases. None of the patients who underwent pancreatic duct stent and/or nasopancreatic drain placement
required surgical intervention. Endoscopic retrograde cholangiopancreatography is the initial test of choice when the diagnosis
of pancreaticopleural fistula is suspected. Early endoscopic intervention with pancreatic duct stent placement is recommended
given its high success rate in fistula closure. Medical therapies are useful adjuncts to endoscopic therapy, but rarely result
in pancreaticopleural fistula closure alone. Surgical interventions should only be considered after failure of endoscopic
and medical therapies. 相似文献

Background
Limited data exists on the long-term outcomes of patients with obscure gastrointestinal bleeding (OGIB) following single-balloon enteroscopy (SBE).Aim
To examine the long-term outcomes of patients undergoing SBE for OGIB.Methods
Consecutive patients undergoing SBE for OGIB at a tertiary care center between 2008 and 2010 were retrospectively identified. Clinical data and SBE findings were extracted from the medical record. Recurrence of OGIB during follow-up through 2012 was assessed by a combination of chart review and telephone interviews.Results
One hundred and forty-seven patients were included in the study. The overall diagnostic yield of SBE was 64.6 % (95/147 patients). Findings of SBE included vascular lesions (VLs, 53.7 %), small bowel neoplasm (2.7 %), inflammatory lesions (4.8 %), and normal SBE (35.4 %). One hundred and ten patients (56.4 % female, mean age 70.6 ± 11.3 years) were followed for an average 23.9 months after initial SBE. During follow-up, OGIB recurred in 39.5 % of patients in whom a source of OGIB was identified on SBE and 55.9 % of patients with normal findings on SBE. OGIB recurred in 47.6 % of patients in whom small bowel VLs were treated endoscopically. None of the 13 patients in whom a non-VL lesion was identified as the source of bleeding on SBE experienced recurrent bleeding (p = 0.019).Conclusions
SBE is a safe and valuable method for managing patients with OGIB. More than 50 % of patients experienced no recurrent bleeding during 2 years of follow-up after SBE. The long-term management of OGIB due to small bowel VLs remains challenging. 相似文献50.
