阑尾炎单病种患者的费用分析

目的：分析实行医保单病种后医保病人与非医保病人阑尾炎治疗的费用差距，提出对医保进一步改革的思索。方法：用Excel 2003建数据表，对我院2005年2月至2006年8月期间收治的单病种收费阑尾炎患者和非单病种收费患者的费用和并发症进行分析并进行统计学处理。结果：阑尾炎治疗并发症发生率及痊愈率在两组间无显著性差异，费用比较两组间差异显著。结论：目前的单病种收费标准基本可以满足临床治疗阑尾炎的需要，同时在实行单病种收费后可以节约大量医疗费用。如进一步扩大单病种范围，用经济手段调动医院的自律机制，医疗费用有进一步下降的空间。     

In vivo anti-melanoma activities of the Melan-A/MART-1101–115 T CD4+ cell peptide

Malignant melanoma causes significant health problems. The identification of tumour-associated antigens has led to novel approaches to increase T cell mediated anti-tumour immune response. Melan-A/MART-1 has been use as target antigen for several T cell based immunotherapeutic treatments. More recently, the critical role of CD4+ T cells in inducing and maintaining anti-tumour immunity has been increasingly recognized. In order to optimize tumour immunotherapy, greater efforts have been concentrated on the identification of tumour antigens presented by MHC class II molecules to CD4+ T cells. In a publication, Tiwari et al. (2004) [1] have identified by a computational approach the 15-mer amino-acid sequence 101–115 (PPAYEKLSAEQSPPP) of the Melan-A/MART-1 as a good target for a vigorous and safe immunotherapy. Therefore, we have investigated the in vivo anti-tumour activity of this peptide in a murine melanoma model. For the prophylactic treatment, 20 μg or 50 μg peptide was subcutaneously injected in mice once a week during 3 weeks before tumour induction. Treatment with 50 μg peptide significantly affected tumour development. Thus, our preliminary data demonstrate potential in vivo prophylactic activity of the 101–115 peptide-based vaccine to control melanoma growth.

介入治疗在颌面部病变中的应用

目的探讨介入治疗在颌面部病变中的应用。方法对44例良、恶性肿瘤和出血病变进行造影和治疗,43例常规进行双侧颈外动脉造影,必要时进行颈内动脉或椎动脉造影。41例进行了治疗,1例因主动脉纡曲而在弓下灌药,2例因其他原因未予栓塞。结果治疗后的患者临床症状均有不同程度的好转或彻底治愈,未出现严重并发症,栓塞后手术的患者术中出血明显减少。结论介入治疗对颌面部病变是一种有效的方法。     

Dissociation of Depletional Induction and Posttransplant Lymphoproliferative Disease in Kidney Recipients Treated With Alemtuzumab

Transplant patients are at the risk for posttransplant lymphoproliferative disease (PTLD), a virally-driven malignancy. Induction with the depleting antibody preparations Thymoglobulin and OKT3 is associated with PTLD suggesting that the T-cell depletion increases PTLD risk. We therefore studied 59 560 kidney recipients from the Organ Procurement and Transplantation Network/United Network for Organ Sharing (OPTN/UNOS) database for a relationship between induction agent use and PTLD. Two agents with comparable T-cell depletional effects, alemtuzumab and Thymoglobulin, were compared to nondepletional induction agents or no induction. The overall incidence of PTLD was 0.46% and differed significantly by induction strategy (p < 0.01): without induction (0.43%), basiliximab (0.38%), daclizumab (0.33%), Thymoglobulin (0.67%) and alemtuzumab (0.37%). Thymoglobulin was associated with significantly increased PTLD risk (p = 0.0025), but alemtuzumab (p = 0.74), basiliximab (p = 0.33) and daclizumab, which trended toward a protective effect (p = 0.06), were not. Alemtuzumab and Thymoglobulin treated patients did not differ in any established parameter affecting PTLD risk although alemtuzumab is known to have a more pronounced B-cell depleting effect. Interestingly, maintenance therapy with an mTOR inhibitor was strongly associated with PTLD (0.71%, p < 0.0001). Thus, depletional induction is not an independent risk factor for PTLD. Rather, maintenance drug selection or perhaps the balance between B- and T-cell depletion may be more relevant determinants of PTLD risk.

Graves甲亢多种治疗方法对Graves眼病影响的系统评价

目的 通过榆索、分析文献系统评价131I、手术、抗甲状腺药物(ATD)治疗Graves病(GD)对Graves眼病(GO)的影响.方法 检索了MEDIJNE(1966年-2006年3月)、EMBASE(1984-2005年)、The Cochrane Library(2006年第1期)、中国生物医学文献光盘数据库(EBMdisc,1978年1月-2006年4月)和中国学术期刊全文数据库(CNKI,1994-2006年)所收录的有关不同GD治疗方法对GO影响的文献,同时从参考文献中追溯文献.对纳入研究的方法学质量进行评价,根据是否采取预防甲状腺功能低下(简称甲低)发生的措施对纳入研究进行亚组分析,结果采用RevMan4.2软件进行统计学分析.结果 最终纳入随机对照研究5项,非随机对照研究2项,病例对照研究1项,共1625例患者.Meta分析显示:如GD治疗后早期未采取措施预防甲低,131I与手术治疗、131I与ATD治疗GD在诱发或加重GO以及减轻GO症状方面莘异有统计学意义[检验值分别为2.31,5.97,3.70,5.55;P均＜0.05];如GD治疗后早期采取措施预防甲低,手术与ATD治疗GD在诱发或加重GO以及减轻GO症状方面差异无统计学意义(检验值分别为0.27,0.99;P均＞0.05),尚无研究涉及131I治疗GD后早期采取甲低预防措施时131I对GO的影响.结论 若未及时采取甲低预防措施,131I较ATD、手术治疗GD更容易诱发或加重GO,减轻GO的症状却不如后两者,对于治疗前已有活动性GO的患者,应慎用131I.     

The effect of immigrant generation and duration on self-rated health among US adults 2003–2007

Global self-rated health (SRH) is increasingly a key indicator in the assessment of immigrant health. However, evidence of the impact on SRH of generational status, duration of residence in the US, and socioeconomic status (SES) among immigrants and their offspring is limited and inconsistent. We overcome limitations in existing research on this topic by using a uniquely large and diverse data source, the March Annual Social and Economic Supplement of the Current Population Survey (CPS; 2003–2007) (n = 637,209). As a result, we are able to disaggregate results by race/ethnicity, account for country of origin, and consider the role of multiple dimensions of SES. We find that overall first-generation immigrants in the US have lower odds of poor/fair SRH compared to the third-generation. This association is particularly strong for blacks and Hispanics but not significant for Asians. Among first-generation Asians and Hispanics, longer duration of residence is positively associated with poor/fair SRH. Finally, socioeconomic gradients in SRH tend to be less pronounced among the first-generation (versus the third) and, within the first-generation, among recent arrivals (versus those with longer durations). Our results highlight the importance of explicitly accounting for multiple immigration-related variables and their interactions with race/ethnicity and SES. Otherwise, studies may misestimate SRH differences by race/ethnicity and socioeconomic status. The continued growth of the US immigrant population and the second-generation underscore the need to examine patterns in immigrant health systematically.
