目的探讨肺癌患者化疗后的癌胚抗原(CEA)、神经元特异性烯醇化酶(NSE)和鳞状上皮细胞癌抗原(SCC-Ag)表达变化。方法选取2017年5月至2020年2月间南京市六合区人民医院收治的100例肺癌患者,将这些患者作为肺癌组,另随机选取同期100例健康体检人员作为健康组。统计分析两组人员化疗前的血清NSE、CEA、SCC-Ag表达水平、肺癌组化疗成功患者化疗前后的血清NSE、CEA、SCC-Ag表达水平、肺癌组化疗失败患者化疗前后的血清NSE、CEA、SCC-Ag表达水平。结果肺癌组患者化疗前的血清NSE、CEA和SCC-Ag表达水平均高于健康组,差异均有统计学意义(均P <0.05)。肺癌组化疗成功患者化疗后的血清NSE、CEA和SCC-Ag表达水平均低于化疗前,均高于健康组,差异均有统计学意义(P <0.05)。肺癌组化疗失败患者化疗后的血清NSE、CEA、SCC-Ag表达水平均高于化疗前,均高于健康组,差异均有统计学意义(P <0.05)。结论对肺癌患者的NSE、CEA、SCC-Ag表达水平进行检测能够将化疗效果有效反映出来,进而有效指导临床的下一步治疗工作,从而有效改善患者预后。  相似文献

Purpose

Mild traumatic brain injury (TBI) is common but accurate diagnosis and its clinical consequences have been a problem. Maxillofacial trauma does have an association with TBI. Neuron-specific enolase (NSE) has been developed to evaluate neuronal damage. The objective of this study was to investigate the accuracy of NSE serum levels to detect mild brain injury of patients with sustained maxillofacial fractures during motor vehicle accidents.

Methods

Blood samples were drawn from 40 healthy people (control group) and 48 trauma patients who had sustained isolated maxillofacial fractures and mild brain injury in motor vehicle accidents. Brain injuries were graded by Glasgow Coma Scale. In the trauma group, correlations between the NSE serum value and different facial fracture sites were also assessed.

Results

The NSE serum level (mean ± SD, ng/ml) in the 48 patients with maxillofacial fractures and mild TBI was 13.12 ± 9.68, significantly higher than that measured in the healthy control group (7.72 ± 1.82, p < 0.001). The mean NSE serum level (ng/ml) in the lower part of the facial skeleton (15.44 with SD 15.34) was higher than that in the upper facial part (12.42 with SD 7.68); and the mean NSE level (ng/ml) in the middle-and lower part (11.97 with SD 5.63) was higher than in the middle part (7.88 with SD 2.64).

Conclusion

An increase in NSE serum levels can be observed in patients sustained maxillofacial fractures and mild brain injury.  相似文献

目的:探究清热化瘀汤联合依达拉奉对急性脑出血患者血清超敏C反应蛋白(hs-CRP)、血浆S100β蛋白和神经元特异性烯醇化酶(NSE)的影响。方法:选择2017年5月—2019年5月在我院神经内科就诊符合纳入标准的80例急性脑出血患者,随机分为联合组(40例)和依达拉奉组(40例),两组均给予基础治疗和依达拉奉静脉滴注治疗,联合组则在此基础上加用清热化瘀汤。观察并比较两组的临床疗效、神经功能缺损程度评分(NIHSS)、格拉斯哥昏迷评分(GCS)、hs-CRP、S100β蛋白和NSE水平及脑血肿量。结果:联合组的总有效率为95%(38/40),显著高于依达拉奉组的总有效率75%(30/40)(P<0.05)。治疗后,两组NIHSS评分降低,GCS评分升高,且联合组NIHSS评分明显低于依达拉奉组(P<0.05),GCS评分高于依达拉奉组(P<0.05)。治疗后,两组hs-CRP、S100β蛋白和NSE水平及均脑血肿量均低于治疗前,且联合组hs-CRP、S100β蛋白和NSE水平及脑血肿量明显低于依达拉奉组(P<0.05)。结论:清热化瘀汤联合依达拉奉对急性脑出血患者具有良好的疗效,可显著改善其神经缺损,降低hs-CRP、S100β蛋白和NSE水平及脑血肿量。  相似文献

Sandblasting is traditionally known as a high-risk profession for potential development of lung silicosis. Reported is a case of a sandblaster with confirmed accelerated silicosis, a condition rather rarely diagnosed in the Czech Republic. Initially, the patient presented with progressive dry cough and exertional dyspnoea. In the early diagnostic process, a possible occupational aetiology was considered given his occupational history and known high-risk exposure to respirable silica particles confirmed by industrial hygiene assessment at the patient’s workplace. The condition was confirmed by clinical, histological and autopsy findings. The patient died during lung transplantation, less than five years from diagnosis.  相似文献

目的探讨微小RNA-124a(miR-124a)和微小RNA-449a(miR-449a)对非小细胞肺癌(NSCLC)的诊断价值。方法选取行手术切除肿瘤的NSCLC患者90例(NSCLC组),出院随访36个月,根据术后复发情况分为复发组(56例)和未复发组(34例)。另选取肺部良性结节患者60例(良性结节组)、健康体检者80名(正常对照组)。收集所有对象的基本资料,同时检测血清神经元特异性烯醇化酶(NSE)、miR-124a和miR-449a水平。采用Spearman相关分析评估各项指标的相关性。采用受试者工作特征(ROC)曲线评估各项指标诊断NSCLC的效能。结果NSCLC组血清NSE水平高于正常对照组和良性结节组(P<0.05),血清miR-124a和miR-449a水平低于正常对照组和良性结节组(P<0.05)。正常对照组与良性结节组之间血清NSE、miR-124a和miR-449a水平差异均无统计学意义(P>0.05)。与未复发组比较,复发组血清NSE水平升高(P<0.05),血清miR-124a和miR-449a水平降低(P<0.05);2个组之间年龄、性别、体质量指数(BMI)、吸烟情况、肿瘤直径、病理类型和TNM分期之间差异均无统计学意义(P>0.05)。ROC曲线分析结果显示,NSE、miR-124a和miR-449a单项诊断NSCLC的曲线下面积(AUC)分别为0.660、0.703、0.759。NSE+miR-124a+miR-449a联合检测诊断NSCLC的AUC(0.895)和敏感性(96.25%)均最高,miR-124a+miR-449a联合检测诊断NSCLC的特异性最高(90.31%)。结论miR-124a和miR-449a或可作为NSCLC的辅助诊断指标。  相似文献

Background

Low-grade malignant endolymphatic sac tumor (ELST) is a rare neoplasm, occurring in the inner ear and invading the temporal bone. This study aims to investigate the clinicopathological features of low-grade malignant ELSTs.

Methods

The clinicopathological data of 21 patients with low-grade malignant ELSTs were collected and analyzed.

Results

The patients were aged 16–71 years, with an average age of 40.3 years and a median age of 39 years, and the male to female ratio was 1:1.6. There were 13 cases (61.9%) of ELSTs occurring on the left side, 7 cases (33.3%) on the right side, and 1 case (4.8%) on both sides. Blood types O and B were noted in 71.4% of the patients. Immunohistochemistry showed that CK, EMA and Vim were all positive, and S-100 (71.4%, 10/14), CD56 (75.0%, 9/12), NSE (50.0%, 2/4), and GFAP (11.1%, 1/9) were also positive, while Syn, CgA, TTF-1, TG, CD34, and calcitonin were negative. The Ki-67 index was 4.3% on average. Histologically, cells were arranged in a papillary shape often with branches and abundant fibrous axial vessel. Some cells had an expanded different-sized thyroid-follicle-like structure, with the follicles containing red-stained colloids and scallop-like secretary vacuoles. There were expanded cavities. Some cases were in a glandular arrangement, and a few in a nest-like, gland-cystoid arrangement. Most tumors were coated with a monolayer of cubic epithelium, a few cells were flat or columnar, with translucent cytoplasm and light staining. The nuclei were oval, nucleolus was not obvious, chromatin was delicate, and a few nucleoli were small. The tissue was prone to bleeding, with fresh and old bleeding. Approximately half of the patients had necrotic bones, and in some cases the tumor tissue had destroyed the surrounding bone. The background fibrous tissue showed hyperplasia with hyaline degeneration, some had calcification and formation of sandy-gravel bodies. The clinical manifestations were hearing reduction or loss, followed by tinnitus, and accompanied by varying degrees of cranial nerve injury. No patients died during follow-up.

Conclusions

Low-grade malignant ELSTs occur most frequently on the left side, with a female preponderance. The disease progressed slowly, with no death, and but relapse in two patients in this series. These tumors are often misdiagnosed.  相似文献
