腕踝针联合耳穴压豆治疗肝癌癌痛的疗效及对心理状态和血清疼痛介质的影响

摘要 目的：观察腕踝针联合耳穴压豆治疗原发性肝癌（PHC）癌痛的疗效及对心理状态和血清疼痛介质的影响。方法：选取湖南中医药大学第一附属医院2020年3月~2022年12月期间收治的PHC癌痛患者117例,按随机数字表法分为对照组和联合组,例数分别为58例和59例。两组患者均接受常规疼痛处理,对照组患者接受耳穴压豆治疗,联合组在对照组的基础上接受腕踝针治疗。对比两组疼痛缓解率、临床指标、心理状态和疼痛介质水平。结果：联合组的疼痛缓解率高于对照组（P<0.05）。联合组的数字疼痛法（NRS）评分低于对照组,止痛起效时间、每次疼痛持续时间短于对照组,爆发痛次少于对照组（P<0.05）。治疗后,两组焦虑自评量表（SAS）、抑郁自评量表（SDS）评分下降,且联合组低于对照组（P<0.05）。治疗后,两组5-羟色胺（5-HT）、P物质（SP）、前列腺素E₂（PGE₂）下降,且联合组低于对照组（P<0.05）。结论：腕踝针联合耳穴压豆治疗PHC癌痛,可有效减轻疼痛症状,降低血清疼痛介质水平,同时还可有效调节患者的心理状态,应用价值较好。

Population prevalence of hereditary breast cancer phenotypes and implementation of a genetic cancer risk assessment program in southern Brazil

In 2004, a population-based cohort (the Núcleo Mama Porto Alegre - NMPOA Cohort) was started in Porto Alegre, southern Brazil and within that cohort, a hereditary breast cancer study was initiated, aiming to determine the prevalence of hereditary breast cancer phenotypes and evaluate acceptance of a genetic cancer risk assessment (GCRA) program. Women from that cohort who reported a positive family history of cancer were referred to GCRA. Of the 9218 women enrolled, 1286 (13.9%) reported a family history of cancer. Of the 902 women who attended GCRA, 55 (8%) had an estimated lifetime risk of breast cancer ≥ 20% and 214 (23.7%) had pedigrees suggestive of a breast cancer predisposition syndrome; an unexpectedly high number of these fulfilled criteria for Li-Fraumeni-like syndrome (122 families, 66.7%). The overall prevalence of a hereditary breast cancer phenotype was 6.2% (95%CI: 5.67-6.65). These findings identified a problem of significant magnitude in the region and indicate that genetic cancer risk evaluation should be undertaken in a considerable proportion of the women from this community. The large proportion of women who attended GCRA (72.3%) indicates that the program was well-accepted by the community, regardless of the potential cultural, economic and social barriers.     

遗传检测综述

目前,遗传检测正在更多的国家、更广泛的范围内被采用。然而,在中国人们还不大熟悉遗传检测的原理、类型、技术、对社会的益处以及国内或国际是如何对它进行管理的。随着遗传检测的广泛使用,正确的监督显得相当必要。对近年来遗传检测所取得的进展进行了粗略的回顾,这将帮助我们对人类遗传学和分子医学革命的新时代有更多的了解。     

No response of plasma substance P, but delayed increase of interleukin-1 receptor antagonist to acute psychosocial stress

Psychosocial stress has been shown to induce inflammatory reactions, followed by the release of immunosuppressive glucocorticoids. This may be mediated by catecholamines or other stress reactive substances such as neuropeptides or cytokines. We here set out to explore the effects of acute psychosocial stress on plasma levels of substance P (SP), a possible mediator of stress-induced inflammatory reactions, and interleukin-1 receptor antagonist (IL-1ra). Twelve healthy male subjects (mean age 27 yrs.) were subjected to the psychosocial stress test "Trier Social Stress Test" (TSST) and a resting control condition. Blood and saliva samples were taken before, as well as 1, 20, 45, and 90 min after TSST or rest, respectively. Salivary cortisol and plasma SP and IL-1ra were measured using immunoassays, salivary alpha-amylase (sAA) was measured by an enzyme kinetic method, and plasma epinephrine (E) and norepinephrine (NE) were measured by HPLC. The TSST induced immediate increases of E, NE, and sAA, and a delayed increase of free cortisol. Plasma IL-1ra showed an even further delayed peak at 90 min after stress. Plasma levels of SP did not respond to stress. No significant associations between changes of stress hormones and IL-1ra or SP were found. We conclude that substance P, epinephrine, and norepinephrine are probably not involved in mediating peripheral inflammation following psychosocial stress, at least with respect to IL-1ra. Further studies have to reveal the mechanisms involved in the stress-induced up regulation of IL-1ra.     

Modelling HIV/AIDS in the presence of an HIV testing and screening campaign

Preventing and managing the HIV/AIDS epidemic in South Africa will dominate the next decade and beyond. Reduction of new HIV infections by implementing a comprehensive national HIV prevention programme at a sufficient scale to have real impact remains a priority. In this paper, a deterministic HIV/AIDS model that incorporates condom use, screening through HIV counseling and testing (HCT), regular testing and treatment as control strategies is proposed with the objective of quantifying the effectiveness of HCT in preventing new infections and predicting the long-term dynamics of the epidemic. It is found that a backward bifurcation occurs if the rate of screening is below a certain threshold, suggesting that the classical requirement for the basic reproduction number to be below unity though necessary, is not sufficient for disease control in this case. The global stabilities of the equilibria under certain conditions are determined in terms of the model reproduction number R₀. Numerical simulations are performed and the model is fitted to data on HIV prevalence in South Africa. The effects of changes in some key epidemiological parameters are investigated. Projections are made to predict the long-term dynamics of the disease. The epidemiological implications of such projections on public health planning and management are discussed.

阻生牙拔除术的临床进展

阻生牙是指由于各种阻力导致不能正常萌出的牙齿的统称,通常阻生牙牙体大部甚至全部埋伏于骨内。阻生牙可导致各种并发症的发生,因此临床上一般主张预防性拔除阻生牙。阻生牙拔除手术因其难度高、风险大、术后反应重一直是口腔牙槽外科关注的重点。近年来随着手术器械、手术观念等方面的进步,阻生牙拔除术取得了一些临床进展。新型CT扫描设备CBCT可以为手术设计提供精确定位;借助各类微创器械,微创拔牙技术减小了手术创伤,降低了手术风险;新型麻醉方式和新型局麻药物可以极大减轻疼痛反应;心理干预也将成为阻生牙拔除患者围手术期管理的重要步骤。本文对近年来阻生牙拔除术在定位方式、微创技术、团队协作、疼痛控制和心理干预等方面的临床进展做一综述。     

心理干预对眶骨骨折患者围手术期的影响

目的:探讨心理干预在眶骨骨折患者围手术期心理应激反应的影响。方法:自2011年8月至2013年02月我院共收治眶骨骨折手术患者60例,随机分为干预组和对照组各30例。干预组分别在术前1日、术后1日进行心理干预,对照组除了不接受心理干预外,其余护理措施同干预组。对两组患者术前焦虑值及生命体征指标(心率)进行测定。应用SPSS12.0软件包进行数据处理。结果:两组患者术前生命体征指标无明显差异,而术前1日和术后1日干预组焦虑值及生命体征指标明显优于对照组。结论:心理干预能改善眶骨骨折患者围手术期的焦虑状态和恐惧情绪,并且能够稳定其生命体征,使患者顺利渡过围手术期,促进术后恢复,在围手术期护理工作中发挥着积极作用。
