老年肺癌患者化疗期间抑郁情况调查及相关因素分析

目的:调查老年肺癌患者化疗期间抑郁情况及分析其相关因素。方法:选取2012年1月至2016年12月在我院化疗的老年肺癌患者300例,调查统计患者的基本信息资料,采用Zung氏自评抑郁量表(SDS)评价患者的抑郁情况,统计患者抑郁情况的调查结果,并采用Logistic回归分析影响老年肺癌患者抑郁的相关因素。结果:300例老年肺癌的患者当中,在化疗期间有抑郁者164例,占54.67%。其中59例是轻度抑郁,占35.98%;90例是中度抑郁,占54.88%;15例是重度抑郁,占9.15%。单因素分析显示,老年肺癌患者抑郁发生率与年龄、收入水平、TNM分期及有无癌症转移有关(均P0.05),与性别、文化程度、癌症分型无关(P0.05)。多因素Logistic回归分析显示影响老年肺癌患者抑郁的相关因素有年龄≥70岁、收入水平3000元/月、TNM分期为Ⅲ~Ⅳ期以及癌症转移(P0.05)。结论:老年肺癌患者在化疗期间较容易出现抑郁症状,临床上应加以重视,年龄≥70岁、收入水平3000元/月、TNM分期为Ⅲ~Ⅳ期以及癌症转移是影响老年肺癌患者抑郁的相关因素,针对相关因素应尽早采取相应的干预措施,从而有利于改善患者的负性心理情绪。

股骨近端防旋髓内钉与联合加压交锁髓内钉治疗老年股骨转子间骨折的疗效比较研究

目的:研究对比股骨近端防旋髓内钉(PENA-Ⅱ)与联合加压交锁髓内钉(Inter Tan)治疗老年股骨转子间骨折的疗效。方法:选择2014年6月至2016年6月我院收治的老年股骨转子间骨折患者92例,按照随机数字表法分为PENA-Ⅱ组与Inter Tan组,每组各46例。两组患者分别接受PENA-Ⅱ治疗和Inter Tan治疗,术后进行为期12个月的随访。比较两组临床疗效、手术相关指标(手术时间、术中出血量、骨折愈合时间)、手术前后骨密度水平变化情况以及并发症发生情况。结果:PENA-Ⅱ组优良率为89.13%,略高于Inter Tan组的86.96%,但两组比较差异无统计学意义(P0.05)。PENA-Ⅱ组患者手术时间、术中出血量分别为(65.2±15.3)min、(57.2±29.3)m L,明显低于Inter Tan组患者的(84.3±13.8)min、(104.7±36.5)m L(P0.05),两组患者骨折愈合时间比较差异无统计学意义(P0.05)。术前、术后12周以及术后24周PENA-Ⅱ组患者的腰椎骨密度水平与Inter Tan组比较差异无统计学意义(P0.05)。两组切口感染、肺部感染、下肢深静脉血拴、近端股骨外侧皮质劈裂以及髋内翻发生率对比差异无统计学意义(P0.05)。结论:PENA-Ⅱ与Inter Tan治疗老年股骨转子间骨折的临床疗效相当,且两种手术方法对骨密度水平的影响及术后并发症发生率相似。但PENA-Ⅱ治疗具有手术时间短以及术中出血量少等优势,值得临床推广应用。

The development of patient information leaflets. Care of the mouth after radiotherapy

Objectives: Describe the methodology used to produce a patient leaflet on care of the mouth after radiotherapy. Design: Prospective study to design a patient information leaflet. Setting and Subjects : Patients undergoing radiotherapy for oral cancer. Intervention: After a review of the relevant literature, a patient questionnaire was produced. This was then completed by patients undergoing radiotherapy treatment and gave an indication of the problems being encountered. Healthcare professionals were surveyed for their views. A leaflet was then produced according to published guidelines. It was taken back to another group of patients and a further version produced after input from a health promotion group. Results: A leaflet was produced after wide consultation and survey. Conclusion: Considerable effort must to be put into the production of patient information leaflet. It must be discussed with patients in the target group if it is to be sensitive, understood and find acceptance among its users     

Ventilation response to CO2 and exercise-induced hypoxaemia in master athletes

Exercise-induced hypoxaemia (EIH) in master athletes may be related to a diminished exercise hyper- pnoea. The aim of this study was to determine whether EIH is associated with a change in the sensitivity of the ventilation response to activation of the central chemoreceptors. The ventilation response to CO₂ was measured in nine elderly untrained men (UT) [mean age 66.3 (SEM 3.1) years] and nine master athletes (MA) [mean age 62.7 (SEM 0.8) years] at rest, during moderate exercise (40% maximal oxygen uptake, V˙O_2max), and during strenuous exercise (70% V˙O_2max) using the rebreathing method. Our results showed that the ventilation response to CO₂ did not differ with endurance training and/or exercise, that the threshold of the CO₂ response (Th) increased with exercise (P < 0.001), that the increase in Th in MA was higher than in UT between rest and moderate exercise [ΔTh_0–40: 8.55 (SEM 1.8) vs 3.06 (SEM 1.72) mmHg, P < 0.05], and that ΔTh_0–40 and Th during moderate exercise were negatively correlated with arterial O₂ saturation during maximal exercise (r = 0.50, P<0.05). We concluded therefore that exercise-induced hypoxaemia in master athletes may not be due to a lower ventilation response to CO₂, but may be partly related to a greater increase in Th during moderate exercise.

Western Blot Detection of Human Anti-Chikungunya Virus Antibody with Recombinant Envelope 2 Protein

Chikungunya virus (CHIKV), a tropical pathogen, has re-emerged and has massive outbreaks abruptly all over the world. Containing many dominant epitopes, the envelope E2 protein of CHIKV has been explored for the vaccination or diagnosis. In the present study, the antigenicity of a recombinant expressed intrinsically disorder domain (IUD) of E2 was tested for the detection of the antibody against CHIKV through western blot method. The gene of the IUD of E2 was inserted into 2 different vectors and expressed as recombinant GST-E2 and recombinant MBP-E2 fusion protein, respectively. Two kinds of fusion proteins were tested with 30 CHIKV patient sera and 30 normal sera, respectively. Both proteins were detected by 25 patients sera (83.3%) and 1 normal serum (3.3%). This test showed a relatively high sensitivity and very high specificity of the recombinant E2 proteins to be used as diagnostic antigens against CHIKV infection.
