肺癌住院患者营养不良风险调查及其影响因素分析

摘要 目的：肺癌住院患者营养不良风险调查及其影响因素分析。方法：选择2015年2月至2020年1月期间我院诊治的125例肺癌住院患者的临床资料进行回顾性分析。根据患者的营养状态评估结果将其分为81例营养不良组和44例营养良好组。比较两组患者的人口学资料和临床资料,采用多因素Logistic回归分析营养不良发生的影响因素。结果：营养不良患者占比64.80%（81/125）。与营养良好组相比,营养不良组年收入≥50000元患者比例明显下降（P<0.05）,营养不良组体质量指数（BMI）≤22 kg/m²患者比例、肿瘤分期III~Ⅳ期+广泛期患者比例以及肿瘤低分化患者比例明显升高,血清白蛋白水平和淋巴细胞绝对值（LYM）明显下降（P<0.05）。经多因素Logistic回归分析显示肿瘤分期III~Ⅳ期+广泛期以及肿瘤低分化是肺癌住院患者营养不良的危险因素（OR=1.743、1.812,P<0.05）,年收入≥50000元、BMI>22kg/m²、白蛋白水平≥29.55 g/L和LYM≥2.47×10⁹/L是肺癌住院患者营养不良的保护因素（OR=0.487、0.502、0.453、0.731,P<0.05）。结论：肺癌住院患者营养不良风险较高,年收入情况、BMI、肿瘤分期、分化程度、白蛋白水平以及LYM均是肺癌住院患者营养不良风险的影响因素,对上述指标进行监测有利于提前预测营养不良的发生,从而为预防肺癌住院患者营养不良的发生提供指导。     

鼻饲中药抗休克合剂治疗重症烧伤休克期患者的疗效及对胃肠道复苏的影响

摘要 目的：探讨中药抗休克合剂经鼻饲给药法治疗重症烧伤休克期患者的疗效及对胃肠道复苏的影响。方法：选取上海中医药大学附属第七人民医院2017年10月至2020年9月期间收治的重症烧伤休克患者共计60例,将其按照随机数字表法分为对照组和实验组,每组各30例。对照组患者进行常规抗休克治疗,实验组在常规抗休克的基础上经鼻饲法给予中药抗休克合剂治疗。观察并记录两组患者复苏前、复苏后1 d、2 d、3 d的动脉血乳酸、内毒素水平,心率、尿量及补液量,腹胀缓解肠鸣音恢复时间、肛门排气时间,消化道不良反应、消化道出血发生率及有无继发全身性感染情况。结果：两组患者经治疗后血清内毒素和动脉血乳酸水平均呈不同趋势下降,复苏后1 d、2 d两组患者实验室指标虽有降低,但两组组间比较差异不显著（P＞0.05）,实验组患者复苏后3 d血清内毒素和动脉血乳酸值下降显著,且明显优于对照组,差异有统计学意义（P＜0.05）。实验组复苏后1 d、2 d补液量均较对照组更低（P<0.05）;实验组复苏后1 d、2 d尿量与对照组比较无统计学差异（P>0.05）,而复苏后3 d尿量较对照组更多（P<0.05）;实验组复苏后1 d、2 d、3 d心率均优于对照组（P<0.05）。实验组腹胀缓解肠鸣音恢复时间、肛门排气时间和消化不良反应、消化道出血、继发全身性感染发生率均低于对照组(P＜0.05)。结论：经鼻饲法给予中药抗休克合剂配合西医常规抗休克治疗,可发挥中医药特色,治疗重症烧伤休克期患者临床疗效明确,有助于胃肠道复苏,降低并发症及感染机率,具有一定的临床价值。     

食管癌组织miR-21、miR-182表达与临床病理特征及预后的关系

目的:探讨食管癌组织微小RNA-21(miR-21)、微小RNA-182(miR-182)表达与临床病理特征及预后的关系。方法:选择2010年10月至2014年2月期间在我院治疗的120例食管癌患者为研究对象,采集患者的食管癌组织及癌旁组织,采用荧光定量PCR检测组织中miR-21、miR-182表达量,采用Kaplan-Meier法分析患者生存情况。结果:与癌旁组织相比,食管癌组织中miR-21、miR-182表达量明显升高(P<0.05)。食管癌组织中miR-21、miR-182表达均与TNM分期和淋巴结转移相关(P<0.05)。miR-21低表达患者的5年生存率明显高于高表达患者(P<0.05),miR-182低表达患者的5年生存率明显高于高表达患者(P<0.05)。结论:miR-21、miR-182表达量在食管癌中上调,与食管癌TNM分期和淋巴结转移相关。miR-21高表达以及miR-182高表达患者5年生存率下降,检测miR-21、miR-182表达量在食管癌患者预后预测中具有一定临床意义。     

多效唑对高粱生长发育及生理的影响

为了解喷施多效唑对高粱(Sorghum bicolor)生长发育和生理的影响,在高粱品种‘农大红1号’拔节期喷施多效唑水溶液,对高粱的生长发育和生理指标进行了研究。结果表明,喷施不同浓度的多效唑后,高粱株高均比对照降低,基部节间长度缩短,茎粗增加,且穗粒重也提高。同时,高粱叶片的叶绿素含量和净光合速率提高,且抗氧化酶活性提高并降低了丙二醛含量。因此喷施多效唑可提高高粱的抗倒伏性,延缓叶片衰老,提高产量。在大田生产中,以拔节期喷施450～600 mg/L多效唑的效果较好。     

A study of oxidative stress in cervical cancer- an institutional study

Cervical cancer is the second most common cause of cancer-related death among women worldwide, especially in developing countries. Oxidative stress has been associated with cervical cancer. Many studies demonstrated that the low level of antioxidants induces the production of free radicals that cause lipid peroxidation, DNA, and protein damage leading to mutations that favors malignant transformation. This is a case-control institutional study conducted to evaluate the level of oxidative stress in cervical cancer patients and the age-matched healthy controls. We measured level of TBARS expressed as MDA, activity of SOD and GSH level by the spectrophotometric method, and level of 8-OHdG was estimated using a competitive sandwich ELISA assay. Our results showed a significant increase in the level of lipid peroxidation in group IV when compared to the control, group II and group III (p < 0.001). The activity of SOD was also significantly higher in group IV when compared to the control group (p < 0.001), group II (p < 0.001), and group III (p < 0.001). The level of GSH was also significantly lower in group IV when compared to the control group (p < 0.01), group II (p < 0.01), and group III (p < 0.01). The level of 8-OHdG was significantly higher in group IV than in the other groups (p < 0.01). The results suggest that oxidative stress is involved in the pathogenesis of cervical cancer, which is demonstrated by an increased level of lipid peroxidation and higher levels of 8-OHdG and an altered antioxidant defense system.     

Argyrophilic nucleolar organizing region associated protein synthesis in hair root cells of humans at different developmental stages and sex

Abstract

Argyrophilic nucleolar organizing region (AgNORs) associated proteins are important for cell proliferation and various diseases. We investigated AgNOR protein synthesis in hair root cells of males and females at different ages using two-dimensional image analysis. Experiments were performed on 58 healthy male and 24 healthy female volunteers in three groups according to age and sex. Hair root cells obtained from hair follicles were stained with silver. Total AgNOR number/total nuclear number (TAN/TNN) and total AgNOR area/nuclear area (TAA/NA) for each nucleus were analyzed. The only significant difference was observed in TAA/NA values for males and females from 6 to 12 years old. We suggest that the difference is due to high NOR activity caused by increased growth hormone production in hair root cells.     

Printed in the Holiday Mood

Teachers' careers are often considered to consist of two parts: pre-service and in-service. In-service refers to the entire time between a teacher's entry and exit from the profession. Recent research suggests teachers' careers actually consistent of several parts, known as phases or stages and, collectively, as the career cycle. This further suggests that as they pass through different stages, teachers' professional development needs may change. This article presents a review of literature on the career cycle, examines the portion known as the “second stage,” and discusses the policy and professional development implications for music teachers.     

Cell-free DNA as a prognostic marker in stage I non-small-cell lung cancer patients undergoing stereotactic body radiotherapy

Abstract

Objective: To evaluate whether plasma cell-free DNA (cfDNA) was related to clinical outcome in inoperable stage I non-small cell lung cancer (NSCLC) patients undergoing stereotactic body radiotherapy (SBRT).

Materials and methods: Plasma cfDNA was assessed at baseline, before the last day and 45 days after the end of SBRT, in 22 NSCLC patients. Twenty-two healthy controls were also evaluated.

Results: Plasma cfDNA was higher in patients than in controls. An association with unfavourable disease-free survival was found for continuous baseline cfDNA increments (HR?=?5.9, 95%CI: 1.7–19.8, p?=?0.04).

Conclusion: Plasma cfDNA may be a promising prognostic biomarker in high-risk NSCLC patients.
