Mesenteric and omental cysts: An ultrasonographic and clinical study of 15 patients

The clinical and ultrasonographic (US) features of 15 cases of mesenteric or omental cyst are herein described. This series included seven male and eight female patients, whose age ranged from 2–89 years. Correct clinical diagnosis was made in two children only, but preoperative US examination accurately demonstrated the lesion in 11 of 13 patients (85%). These cystic lesions usually had a thin wall, internal septations, and fluid content with sedimentation. Enteric duplication cysts had a relatively thick wall merging with the muscle layer of bowel loop, and multiloculation was noted mainly with cystic lymphangiomas or pseudocysts. The diagnostic and surgical management of these lesions are briefly reviewed and their US appearance is illustrated.     

头颈部肿瘤放疗对甲状腺功能的损伤

头颈部肿瘤放疗后会引起不同程度的甲状腺功能减退.引起甲状腺功能减退的机制包括射线对甲状腺及垂体细胞的直接损伤、对相关血管的损伤以及自身免疫反应等.影响头颈部肿瘤放疗后甲状腺功能的因素主要有:放疗剂量、放疗技术、是否联合手术化疗等.通过对这些影响因素的研究可为防治甲状腺功能减退提供依据,从而提高患者生活质量.     

识时度势保持特色力求发展--中西医合校的回顾与思考

新疆医科大学为全国第二家中西医合并院校.在新疆进行中西医合校,实属时势所使,事在必行.强弱相合,处于弱势的中医学院只有坚持相对独立,才能保证于合校后发扬中医药特色、办好中医药教育.中西医合校,给原本弱小的新疆高等中医药教育事业的发展带来了诸多可供凭借和利用的积极因素,同时也存在不少负面影响.新疆医科大学在实践中认清了中西医同校的优势与缺憾,采取扶持和爱护中医的策略,不断尝试规避冲突、化解矛盾、趋利祛弊、务期和谐,终喜事业有成,使高等中医药教育得以在新疆生存,并越过低谷,走上健康发展之路.     

胶原酶诱导不同部位脑出血大鼠模型的神经功能比较

目的 观察胶原酶诱导纹状体和内囊部位脑出血模型的行为学和神经纤维损伤差异.方法 利用立体定向技术,将一定量的Ⅳ型胶原酶用微量进样器分别精确注入大鼠纹状体和内囊诱导脑出血模型,观察两组大鼠的运动功能差异,并进行大体形态学和神经纤维受损程度的比较.结果 内囊组大鼠的运动功能受损程度明显重于纹状体组大鼠,前者的神经纤维破坏程度显著重于后者.结论 不同部位的脑出血模型的神经损害程度存在差异,内囊区脑出血模型更适合于研究神经纤维的损伤机制及神经纤维的再生和修复.     

急诊抗菌药物的使用调查与分析

目的考察了解急诊抗菌药物的使用情况。方法随机抽取2008年7—12月的急诊处方2700张，对其中抗菌药物的应用情况进行统计分析。结果急诊抗菌药物使用率49．1％，药物应用形式以单用为主（占66．3％）；给药途径以口服和静脉注射为主。不合理用药处方占抗菌药物处方的10．8％，分别在选药方案、给药方案、溶媒使用、联合应用等方面存在问题。结论我院急诊抗菌药物的应用基本合理，但仍存在一定问题，需进一步加强管理。     

Bacterial ghosts (BGs)—Advanced antigen and drug delivery system

Bacterial ghosts (BGs) are empty bacterial envelopes of Gram-negative bacteria produced by controlled expression of cloned gene E, forming a lysis tunnel structure within the envelope of the living bacteria. BGs are devoid of cytoplasmic content and possess all bacterial bio-adhesive surface properties in their original state while not posing any infectious threat. BGs are ideally suited as an advanced drug delivery system (ADDS) for toxic substances in tumor therapy. The inner space of BGs can be loaded with either single components or combinations of peptides, drugs or DNA which provides an opportunity to design new types of (polyvalent) drug delivery vehicles. Uptake of BGs loaded with Doxorubicin (Dox) by CaCo2 cells led to effective Dox release from endo-lysosomal compartments and accumulation in the nucleus. Viability and proliferative capacity of the cells were significantly decreased (2–3 orders of magnitude) after internalization of Dox loaded BGs as compared to cells incubated with free Dox. The same effect was observed with leukemia cells. Melanoma cells also revealed a high capability to internalize BGs. These results indicate that BGs are able to target a range of types of cancer. BGs have also been investigated as DNA delivery vectors. Studies show DNA loaded BGs are efficiently phagocytosed and internalized by both professional APCs and tumor cells with up to 82% of cells expressing the plasmid-encoded reporter gene. Our studies with BGs as an ADDS system contribute (i) to optimize drug delivery for the treatment of cancer; (ii) define specific conditions for selection and preparation of BG formulations; (iii) and provide a background for the clinical application of BGs in cancer therapy.     

Psychosocial Effects of Physical and Verbal Abuse in Postmenopausal Women

PURPOSE The purpose of this study was to examine the psychological effects of physical and verbal abuse in a cohort of older women.METHODS This observational cohort study was conducted at 40 clinical sites nationwide that are part of the Women’s Health Initiative (WHI) Observational Study. We surveyed 93,676 women aged 50 to 79 years using the mental health subscales and the combined mental component summary (MCS) score of the RAND Medical Outcomes Study 36-item instrument.RESULTS At baseline, women reporting exposure to physical abuse only, verbal abuse only, or both physical and verbal abuse had a greater number of depressive symptoms (1.6,1.6, and 3 more symptoms, respectively) and lower MCS scores (4.6, 5.4, and 8.1 lower scores, respectively) than women not reporting abuse. Compared with women who had no exposure to abuse, women had a greater increase in the number of depressive symptoms when they reported a 3-year incident exposure to physical abuse only (0.2; 95% confidence interval [CI], −0.21 to 0.60), verbal abuse only (0.18; 95% CI, 0.11 to 0.24), or both physical and verbal abuse (0.15; 95% CI, −0.05 to 0.36); and they had a decrease in MCS scores when they reported a 3-year incident exposure to physical abuse only (−1.12; 95% CI, −2.45 to 0.12), verbal abuse only (−0.55; 95% CI, −0.75 to −0.34), and both physical and verbal abuse (−0.44; 95% CI, −1.11 to −0.22) even after adjustment for sociodemographic characteristics.CONCLUSION Exposure to abuse in older, functionally independent women is associated with poorer mental health. The persistence of these findings suggests that clinicians need to consider abuse exposure in their older female patients who have depressive symptoms. Clinicians caring for older women should identify women at risk for physical and verbal abuse and intervene appropriately.
