顺铂聚乳酸微球的药物释放特性及肝动脉栓塞研究 总被引:5,自引:0,他引:5
对顺铂聚乳酸微球进行了体外药物释放和家犬肝动脉栓塞研究。该微球粒径范围为50~200μm,平均粒径为115.76±35.94μm,顺铂含量为37.16%(W/W);体外药物释放机制符合Higuchi方程;肝动脉栓塞后8h,肝组织顺铂浓度高达21.55±12.18μg/g,明显高于肝动脉灌注顺铂组:3.16±0.09μg/g(P<0.05);肝动脉栓塞组的顺铂血浓峰值、各取血点浓度及曲线下面积AUC皆低于肝动脉灌注顺铂组。可望达到提高栓塞部位的药物疗效,降低全身毒副反应的作用。 相似文献

OBJECTIVE: Schizophrenic patients who are only partially responsive to clozapine pose a therapeutic challenge. In these circumstances some clinicians would consider adding in a second antipsychotic. We present a case report and review evidence for the efficacy of such augmentation strategies. METHOD: Single case report and literature review. RESULTS: The total number of patients in studies and case reports of combining clozapine with other antipsychotics is small. There has been only one randomized controlled trial. This found the addition of sulpiride to clozapine resulted in clinical improvement in some patients. CONCLUSION: Further randomized controlled studies of augmentation of clozapine therapy are needed to provide scientific justification for this clinical practice. 相似文献

Background and ObjectiveThoracic surgery causes significant pain which can negatively affect pulmonary function and increase risk of postoperative complications. Effective analgesia is important to reduce splinting and atelectasis. Systemic opioids and thoracic epidural analgesia (TEA) have been used for decades and are effective at treating acute post-thoracotomy pain, although both have risks and adverse effects. The advancement of thoracoscopic surgery, a focus on multimodal and opioid-sparing analgesics, and the development of ultrasound-guided regional anesthesia techniques have greatly expanded the options for acute pain management after thoracic surgery. Despite the expansion of surgical techniques and analgesic approaches, there is no clear optimal approach to pain management. This review aims to summarize the body of literature regarding systemic and regional anesthetic techniques for thoracic surgery in both thoracotomy and minimally invasive approaches, with a goal of providing a foundation for providers to make individualized decisions for patients depending on surgical approach and patient factors, and to discuss avenues for future research.MethodsWe searched PubMed and Google Scholar databases from inception to May 2021 using the terms “thoracic surgery”, “thoracic surgery AND pain management”, “thoracic surgery AND analgesia”, “thoracic surgery AND regional anesthesia”, “thoracic surgery AND epidural”. We considered articles written in English and available to the reader.Key Content and FindingsThere is a wide variety of strategies for treating acute pain after thoracic surgery, including multimodal opioid and non-opioid systemic analgesics, regional anesthesia including TEA and paravertebral blocks (PVB), and a recent expansion in the use of novel fascial plane blocks especially for thoracoscopy. The body of literature on the effectiveness of different approaches for thoracotomy and thoracoscopy is a rapidly expanding field and area of active debate.ConclusionsThe optimal analgesic approach for thoracic surgery may depend on patient factors, surgical factors, and institutional factors. Although TEA may provide optimal analgesia after thoracotomy, PVB and emerging fascial plane blocks may offer effective alternatives. A tailored approach using multimodal systemic therapies and regional anesthesia is important, and future studies comparing techniques are necessary to further investigate the optimal approach to improve patient outcomes. 相似文献

Background
Fractures of the intertrochanteric hip are common and the treatment of unstable fractures generally requires an operative approach. In elderly patients, osteoporosis makes internal fixation problematic and frequently contributes to failed fixation and poor clinical results. We have attempted to apply the Less Invasive Stabilization System (LISS) in reverse position for the repair of intertrochanteric hip fractures in elderly patients with osteoporotic bones. A retrospective review is presented of the cases of 28 elderly patients with stable and unstable fractures of the intertrochanteric hip treated using the reverse LISS. 相似文献8.

Background
Smear-negative pulmonary tuberculosis (SNPTB) accounts for 30% of Pulmonary Tuberculosis (PTB) cases reported annually in developing nations. Polymerase chain reaction (PCR) may provide an alternative for the rapid detection of Mycobacterium tuberculosis (MTB); however little data are available regarding the clinical utility of PCR in SNPTB, in a setting with a high burden of TB/HIV co-infection. 相似文献9.

Cells were treated in vitro with oligodeoxyribonucleotide phosphorothioates (ODNs) complementary to sites common to both wild-type and mutant p53 nucleotide sequences. Acute myelogenous leukemia (AML) blasts from peripheral blood were exposed to four different p53 ODNs and showed anti-leukemic effects in suspension culture. This effect continued after removal of the ODN from the medium. Blocking of self-renewal of the leukemic blast stem cells in secondary plating of cells from cloning assays by two of the p53 ODNs was also observed. Control ODNs had no effect on leukemic blasts. Treatment of normal bone marrow cells with the four p53 ODNs did not influence their growth, nor was there any effect by the p53 ODNs on the leukemic cell-line, HL60, that does not express p53. These data suggest that p53 ODNs are selectively toxic to primary myelogenous blasts and may be therapeutically useful in AML. 相似文献

OBJECTIVE: To evaluate the growth, feeding and health of babies fed a novel infant formula milk with added long chain polyunsaturated fatty acids (LCPs) produced from single-cell sources, at concentrations similar to those found in mature breast milk. DESIGN: Randomized double-blind control trial. SUBJECTS: One-hundred and forty healthy, full-term infants of birth weight 2.5-4.5 kg born at the Maternity Department, East Glamorgan General Hospital, Wales, whose mothers had already decided to bottle feed. INTERVENTIONS: Subjects were randomized to two groups; one (control group) to receive a standard formula milk and the other to receive the trial milk with added LCPs. Milks were supplied in a double-blind fashion and given for the first 12 weeks of life. Anthropometric measurements were made at recruitment, 3 months, 6 months and 1 y. Feeding diaries were completed at 6 weeks and 3 months, and a parental record was kept of any ill health suffered by the subjects during the first year of life. RESULTS: Of 140 infants recruited, 31 did not complete the protocol. Small but statistically significant differences were found only in the subscapular skinfold thickness at 6 weeks and 3 months, that in the trial group being slightly higher, but unlikely to be of any clinical importance. No differences were found in the feeding patterns of the infants in the two groups. Stool patterns were similar, as were the frequencies of illness and allergy. CONCLUSIONS: This study supports the view that LCPs from single-cell sources do not have detrimental effects on the growth, feeding and general health of infants. 相似文献
