The occurance of tumor indicates to some extent the failure of this "immune serveillance" function.

Tumorassociated antigens are not unique to tumor cells, and can also be synthesized in small amounts by normal cells. Tumor-specific antigens, also called neoantigens, are formed by peptides that are entirely absent from the normal human genome [1]. Neoantigens are展开更多

Methods With a temperature-controlled multi-electrode needle, ultrasound-guided PRFA was employed to treat forty-seven patients with 67 tumor nodules, with a diameterof 2.6 ± 1.1 cm (1.0 - 5.5 cm). Results A complete ablation (CA) rate of 80. 6% was achieved in the present series, with a CA rate of 91.7 % in the tumors ≤3 cm in diameter,75. 0% in tumors from 3.1 to 4. 0 cm,and 14. 3% in tumors 】4 cm. The CA rate was significantly greater in tumors with a temperature rising up to 70℃ within the initial 2 minutes at ablation as compared with that longer than 2 minutes (P 【 0.05). A markedly higher CA rate was obtained in tumors with an ablation-maintaining temperature of over 80℃ than that between 70℃ and 80℃ ( P 【 0. 01).

Due to its characteristics of superior flocculation effect, without secondary pollution to the environment and being easily degraded, MBF has been emerging as a hotspot of water treatment research in recent years. In this paper, the latest progress of the preparation of MBFs and the flocculating mechanism were presented. The practical application research of MBFs for water treatment was reviewed. Finally, suggestions and development prospect of research on MBFs were discussed.展开更多

Methods: A total of 2,038 patients with CPD were enrolled at 3 independent hospitals (defined as Groups A, B and C, respectively) in China. All patients were treated by SAAT, as applying a herbal paste onto the acupoints of Fengmen (BL 12) and Feishu (BL 13) on the dog days of summer, according to the lunar calendar, in 2008. Ten days after treatment, skin reaction data (no reaction, itching, stinging, blistering, and infection) were obtained via face-to-face interviews. Patients were retreated in the same hospital one year later, thereby allowing doctors to assess treatment efficacy based on the patients' symptoms, the severity of the spirometric abnormalities, and the concomitant medications used. Results: A large number of patients (85.3%) displayed reactive symptoms; however, the marked associations between reactive symptoms and age or gender were not observed. An increased number of patients from Group B (99.3%) and Group C (76.5%) displayed reactive symptoms due to the increased mass of crude Semen Sinapis Albae. The effective rate of SPAT was as high as 90.4% for patients of Group B, which was followed by Group A (70.9%) and Group C (42.2%). Using stratified analyses, a convincing association between reactive symptoms and therapeutic efficacy was observed for patients with asthma [itching: odds ratio (OR)=2,17, 95% confidence interval (CI): 1.49 to 3.14; blistering: OR=0.43, 95% Ch 0.25 to 0.73; and no reaction: OR=0.56, 95% CI: 0.35 to 0.90]. However, the same tendency was not observed for patients with chronic bronchitis and chronic obstructive pulmonary disease. Conclusions: SAAT can induce very mild skin reactions for patients with CPD, among which patients with asthma displayed a strong association between skin reactions and therapeutic efficacy. The skin reactions may be induced by the crude Semen Sinapis Albae.展开更多

This contribution provides an overview of iron oxide MNPs used in environmental, biomedical, and clinical fields. The first part discusses the use of MNPs for environmental purposes, such as contaminant removal, remediation, and water treatment, with a focus on the use of zero-valent iron, magnetite (Fe304), and maghemite (~,-Fe203) nanoparticles, either alone or incorporated onto membrane materials. The second part of this review elaborates on the use of MNPs in the biomedical and clinical fields with particular attention to the application of superparamag- netic iron oxide nanoparticles (SP1ONs), which have gained research focus recently owing to their many desirable features such as biocompatibility, biodegradability, ease of synthesis and absence of hysteresis. The properties of MNPs and their ability to work at both cellular and molecular levels have allowed their application in vitro and in vivo including drug delivery, hyperthermia treatment, radio-therapeutics, gene delivery, and biotherapeutics. Physiochemical properties such as size, shape, and surface and magnetic properties as well as agglomeration of MNPs and methods to enhance their stability are also discussed.展开更多
