Background: It has been reported that cystine and theanine, amino acids related to glutathione synthesis, have immunomodulatory effects, such as suppressing inflammation after strenuous exercise. In this study, we examined the effects of oral administration of cystine and theanine during the perioperative period as a pilot study. Methods: Forty‐three cases of distal gastrectomy for cancer conducted in our department were assigned to the cystine and theanine group (CT group) or to the placebo control group (P group), and a randomized, single‐blind, parallel‐group study was then performed. Cystine (700 mg) and theanine (280 mg) or a placebo was administered to participants for 10 continuous days (4 days before to 5 days after surgery). Changes in pre‐ and postoperative interleukin (IL)–6, C‐reactive protein (CRP), albumin, white blood cell (WBC) count, neutrophil count, total lymphocyte count, resting energy expenditure (REE), and body temperature were compared and examined. Results: Ten patients were excluded, leaving 33 patients in the study. The CT group had significantly lower IL‐6 values (postoperative day [POD] 4), CRP levels (POD 7), neutrophil counts (POD 4), and body temperatures (POD 5) than the P group (P < .05). In addition, REE in the P group peaked on day 1 (1.14 ± 0.16 [pre‐ and postoperative ratio]), whereas the CT group did not show any increase on POD 1 (0.99 ± 0.21, P < .05 vs P group). Conclusions: This study suggests that oral administration of cystine and theanine during the perioperative period may alleviate postgastrectomy inflammation and promote recovery after surgery.  相似文献

Structural bone allografts are used to reconstruct large skeletal defects after tumor surgery. Although allograft-related complications are declining, the use of perioperative radiation therapy is associated with a poorer outcome. Recently, BMP-2 levels in the host bed were reportedly diminished after exposure to radiation doses consistent with those used perioperatively to treat musculoskeletal sarcoma. Reintroduction of this osteogenic protein may circumvent the deleterious effects of preoperative radiation on allograft incorporation. We introduced a novel polymeric BMP-2 gene delivery system into the host-allograft junctions at the time of transplantation in an ovine tibial defect model with or without preoperative exposure to 50 Gy radiation. After 4 months, we noted no radiographic or histologic improvements in allograft incorporation after preoperative radiation and BMP-2 reintroduction; however, 50 Gy radiation was associated with increased porosity in the interface regions and poorer radiographic healing. We identified no BMP2-expressing cells or protein in the interface at the study end point, suggesting the polymeric gene delivery system was unable to promote extended expression of the protein or induce a healing response. Although gene therapy may hold promise as a novel technique to improve allograft incorporation, our data do not support that contention with the current approach. Each author certifies that he or she has no commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article. This work was made possible through financial assistance provided by the Musculoskeletal Transplant Foundation. Each author certifies that his or her institution has approved the animal protocol for this investigation and that all investigations were conducted in conformity with ethical principles of research.  相似文献

Routine screening of women for intimate partner violence (IPV) has been introduced in many health settings to improve identification and responsiveness to hidden abuse. This cross‐sectional study aimed to understand more about how women use screening programmes to disclose and access information and services. It follows women screened in ten Australian health care settings, covering antenatal, drug and alcohol and mental health services. Two samples of women were surveyed between March 2007 and July 2008; those who reported abuse during screening 6 months previously (122) and those who did not report abuse at that time (241). Twenty‐three per cent (27/120) of women who reported abuse on screening were revealing this for the first time to any other person. Of those who screened negative, 14% (34/240) had experienced recent or current abuse, but chose not to disclose this when screened. The main reasons for not telling were: not considering the abuse serious enough, fear of the offender finding out and not feeling comfortable with the health worker. Just over half of both the positive and negative screened groups received written information about IPV and 35% of the positive group accessed further services. The findings highlight the fact that much abuse remains hidden and that active efforts are required to make it possible for women to talk about their experiences and seek help. Screening programmes, particularly those with established protocols for asking and referral, offer opportunities for women to disclose abuse and receive further intervention.  相似文献

Optic nerve breast metastasis mimicking meningioma   总被引:1,自引:0,他引:1  
Purpose: We report on an optic nerve breast metastasis masquerading initially as a central retinal vein occlusion and later as an optic nerve meningioma. Methods: A 60-year-old female presented with a left central retinal vein occlusion (CRVO). She represented 7 months later with left upper ptosis, proptosis and painful rubeotic glaucoma. Computed tomography (CT) and magnetic resonance imaging suggested an optic nerve meningioma. On referral to the regional orbital unit, a mild left external ophthalmoplegia was noted and, in view of previous right mastectomy and chemotherapy 3 years earlier, the left optic nerve was biopsied simultaneously with left enucleation of her painful eye. Results: Histopathology showed infiltration of the optic nerve and meningeal sheath spreading into the subretinal space and vitreous by malignant epithelial cells, consistent with breast origin. Further CT imaging and bone scans revealed no other metastases. Single field left orbit radiotherapy of 20 Gy was given in five fractions and Arimidex (Zeneca Pharmaceuticals, Cheshire, England) was commenced with the cessation of tamoxifen. The patient was also given an ocular prosthesis. Sadly, she lost vision in her other eye due to retrograde malignant invasion of her optic chiasm and died 6 weeks later. Conclusions: Orbital and choroidal metastases are relatively common but isolated optic nerve metastases are extremely rare. Progressive infiltration of the nerve is likely to enhance CRVO ischaemia and resultant rubeotic glaucoma. In the diagnosis of CRVO, proptosis or external ophthalmoplegia, the presence of pre-existing malignant disease should raise concerns, as delay in diagnosis may affect outcome, particularly if the metastases are sensitive to pharmacological therapy.  相似文献
