目的 儿童流感相关坏死性脑病(influenza-associated necrotizing encephalopathy,IANE)是一种严重的流感并发症,目前缺乏早期诊断预警指标,本文探讨血生化和脑脊液检测在儿童IANE早期预警中的作用,为IANE早期诊断提供预测参考。 方法 回顾分析2016年1月—2020年12月在我院接受诊治的确诊流感并发神经系统并发症的患儿。40例流感相关性脑病(influenza-associated encephalopathy,IAE)和32例IANE患儿纳入研究。采用受试者工作特征曲线(ROC)分析来确定所选变量的预警价值。 结果 与IAE组相比,IANE组丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、肌酐激酶(CK)、乳酸脱氢酶(LDH)、脑脊液乳酸脱氢酶(CSF LDH)、脑脊液蛋白(CSF PRO)均升高,两组差别有统计学意义(P<0.05)。用于区分IAE和IANE的LDH、CSF LDH和CSF PRO的曲线下面积(AUC)分别为0.876、0.853和0.831。LDH>535 U/L预测IANE的敏感度为89.7%,特异度为86.5%。CSF LDH>67 U/L预测IANE的敏感度为82.8%,特异度为73.3%。CSF PRO>0.49 g/L预测IANE的敏感度为73.7%,特异度为76.6%。IANE患儿死亡10例(43.3%),IAE患儿死亡0例(P<0.05)。 结论 IANE组LDH、CSF LDH和CSF PRO明显升高,可作为IANE的早期预警指标。对此类患儿要密切评估,早期预测及干预,减少后遗症及病死率,改善预后。

Objective Influenza-associated necrotizing encephalopathy (IANE) in children is a serious complication of influenza. At present, there is a lack of indicators for early diagnosis and early warning. In this paper, the role of blood biochemical and cerebrospinal fluid detection in early warning of IANE in children is discussed, so as to provide a predictive reference for early diagnosis of IANE. Methods A retrospective analysis was conducted on children diagnosed with influenza and with neurological complications who were treated in our hospital from January 2016 to December 2020. Forty children with influenza-associated encephalopathy (IAE) and 32 children with IANE were included. Receiver operating characteristic curve (ROC) analysis was used to determine the predictive value of the selected variables. Results Compared with IAE group, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine kinase (CK), lactate dehydrogenase (LDH), cerebrospinal fluid lactate dehydrogenase (CSF LDH) and cerebrospinal fluid protein (CSF PRO) were all increased in IANE group, and the differences between the two groups were statistically significant (P<0.05). The area under curve (AUC) of LDH, CSF LDH and CSF PRO used to distinguish IAE from IANE were 0.876, 0.853 and 0.831, respectively. The sensitivity and specificity of LDH>535 U/L for predicting IANE were 89.7% and 86.5% respectively. The sensitivity and specificity of CSF LDH>67 U/L for predicting IANE were 82.8% and 73.3% respectively. The sensitivity and specificity of CSF PRO＞0.49 g/L in predicting IANE were 73.7% and 76.6%. There were 10 deaths of IANE (43.3%) and 0 death of IAE (P<0.05). Conclusion The levels of LDH, CSF LDH and CSF PRO were significantly increased in IANE group, which could be used as early warning indicators for IANE. For such children, close evaluation, early prediction and intervention should be made to reduce sequelae and fatality rate and to improve prognosis.

Objective To explore the feasibility of individualized low rate contrast agent injection scheme combined with low tube voltage scanning in CTA imaging of low body mass index(BMI) subjects' head and neck. Methods Ninety cases of head and neck CTA examination of low BMI subjects in our department from January 2020 to November 2020 were selected for the study, and randomly divided into three groups with 30 cases in each group. Group A applied 80 kV scanning, low flow rate and low total volume injection scheme. Group B applied 120 kV scanning, high flow rate, low total volume injection scheme. Group C applied 120 kV scanning, high flow rate and high total volume injection scheme. The injection velocity, injection volume, radiation dose length product (DLP) among three groups were compared. In each image of the aortic arch, common carotid artery, basilar artery and the central part of sternocleidomastoid, the CT value, the signal-to-noise ratio and contrast-to-noise ratio were evaluated. Two experienced radiologists performed image quality evaluation. Results Image quality in group A and B by subjective evaluation got 4 points out of 4, and group C got 3 points out of 4, and there was statistical difference between group A, B and C in subjective evaluation of image quality (P<0.05). The injection velocity and DLP of contrast agent in group A were 27.75% and 47.10% lower than those in group B and C, respectively. The total amount of contrast agent injection in groups A and B was decreased by 39.87% compared with group C, with statistical difference (P<0.05). The corresponding CT values of each vessel in group A were slightly higher than those in group B and C, and there were statistically significant differences in the Objective parameters of other vessels except for aortic arch (P<0.05). Conclusion The combination of individualized low flow rate and precise contrast agent injection scheme with low tube voltage scanning technology for low BMI subject could not only reduce the injection rate and risk of contrast agent, but also reduce radiation dose, on the premise of meeting the diagnostic requirements of image quality. It is worthy of popularization and application.

Objective To analyse the factors that lead to venous thrombosis among breast cancer patients who need totally implantable access port(TIAP) for chemotherapy. Methods Collecting the clinical data of 60 breast patients admitted to Guanzhou First People's Hospital from May 2018 to April 2019, analysed with SPSS 26.0. Results Catheter-related thrombosis(CRT) occurred in 21 out of 60(35%) patients with TIAP. 30.3% patients with BMI≤24 and 40.74% patients with BMI＞24 had CRT, and incidences of CRT were 20%, 33.34%, 44.12% at the fourth, sixth, eighth therapy respectively. The access terminal position at T5-T8 had 66.67%, 26.09%, 28.57%, 50% of incidence for CRT respectively. 27.5% CRT was with high Ki-67 expression and 50% CRT was with low Ki-67 expression; 47.62% patients with polyurethane catheter and 28.21% patients with silicone catheter got CRT. There were no significant differences in the comparisons above. CRT incidence in ER/PR negative patients was 60%,while 23.08% in ER/PR positive patients (P＜0.05). In HER-2 positive and negative patients, the incidences of CRT were 50% and 23.53% (P＜0.05). Logistic regression noticed that ER/PR negative would increase the incidence of CRT(OR=4.482, 95%CI:1.116～17.998, P＜0.05), low Ki-67 expression would accelerate CRT(OR=7.051, 95%CI:1.513～32.858, P＜0.05). There was no significant difference in the formation of CRT with HER-2 expression(OR=0.254, 95%CI:0.058～1.115, P＞0.05). Conclusion CRT was a common complication of TIAP, which related with ER/PR expression, and should pay attention to during clinical practices.

Objective To evaluate the value of neutrophil-lymphocyte ratio (NLR) in the chemotherapy curative effect and prognosis of patients with advanced colorectal cancer (CRC). Methods Retrospective collection of clinical data from 50 patients with advanced unresectable colorectal cancer who received oxaliplatin-based standard first-line chemotherapy between January 2016 and April 2019. Chemotherapy curative effect was evaluated following 2 chemotherapy cycles. Calculation of neutrophil to lymphocyte ratio (NLR) based on pre-chemotherapy hematology data. The receiver operating characteristic curve was used to determine the optimal cutoff value of NLR,according to patients who were divided into groups of high NLR(NLR≥3.785)and low NLR(NLR≥3.785).The differences between high and low NLR and clinicopathological features, efficacy of chemotherapy, progression-free survival (PFS), and total survival (OS) were compared. COX regression analysis mode was used to analysis of factors affecting PFS and OS in patients with advanced colorectal cancer. Results The differences in tumor differentiation (P=0.030), ECOG score (P=0.003), CEA (P=0.011), CA19-9 (P=0.047) in the high and low NLR groups were statistically significant. The differences in chemotherapy between the two groups was statistically significant (P<0.001), and the high NLR group was less effective. The median PFS of the high and low NLR groups were 3.44 months and 12.84 months, respectively, and the difference was statistically significant (χ²=39.730, P<0.001). The median OS of the high and low NLR groups was 7.59 months and 22.32 months, respectively, and the difference was statistically significant (χ²=40.505, P<0.001). Cox regression analysis suggested that NLR levels and CEA levels were independent prognostic factors for PFS and OS(P＜0.05). Conclusion High-level NLR is associated with poor chemotherapy response and poor prognosis in patients with advanced colorectal cancer, and was used as an indicator of chemotherapy efficacy and prognosis.
