目的 分析异种脱细胞基质在腮腺手术中的应用价值。方法 分析97例在我科行腮腺手术的患者,其中观察组52例在腮腺全部或者部分切除后术腔植入异种脱细胞基质生物膜,另外对照组45例术后术腔未放置任何移植物以及其他自体组织填充于术腔,只给予逐层缝合,对比两组患者手术时间、术后引流总量、引流管拔除时间、术后疼痛程度以及涎腺瘘的发生率。结果 两组患者手术时间无差异,观察组的术后引流总量、引流管拔除时间、术后疼痛程度以及术后涎腺瘘的发生率均少于对照组。结论 异种脱细胞基质置入腮腺术后术腔内,可减少术腔引流管放置的时间,减轻患者术后的不适感,降低涎腺瘘的发生率,病人可获益。

Objective To evaluate the effect of heterogeneous acellular dermal matrix in parotidectomy. Methods Ninety-seven patients underwent parotidectomy in our hospital were divided into two groups, including 52 cases implanted biofilm of heterogeneous acellular dermal matrix in parotid gland cavity after total or partial resection as observation group, and 45 cases of postoperative cavitywere not filled graft or other autologous tissue, only given demixing suture as control group. The operation time, total amount of postoperative drainage, drainage tube removal time, postoperative pain degree and the sialosyrinx incidence were compared between two groups after surgery. Results There was no statistical difference in the operation time between the two groups. The total amount of postoperative drainage, the drainage tube removal time, the postoperative pain degree and sialosyrinx incidence in the observation group were all lower than those in the control group. Conclusion Heterogeneous acellular dermal matrix implantation is an effective method to reduce the time of placing the drainage tube in the operative cavity, relieve the postoperative discomfort, and reduce sialosyrinx incidence after parotidectomy, which can benefit the patients.

目的 通过对广东地区流行季节的发热新生儿肠道病毒感染临床特点及高危因素探讨,对高危患儿采取有效防治措施。方法 以2019年5月—10月广东省妇幼保健院门诊因发热收治入院的诊断为肠道病毒感染28例新生儿为研究对象,回顾性分析这些患儿的临床资料,分析新生儿肠道病毒感染的高危因素。结果 因发热收治入院的新生儿检测后肠道病毒感染发病率达38.3%,热峰高于38.5℃,发热持续时间大于3 d、细菌培养阴性是新生儿肠道病毒感染的高危因素。结论 在肠道病毒流行季节,对发热新生儿均应常规进行肠道病毒检测,肠道病毒感染患儿,经过有效的治疗后,能够取得较好的治疗效果,但需及时控制病毒的传播途径,针对相关危险因素进行有效的控制,从而降低发病率。

目的 初步探讨D-二聚体对判断女性恶性肿瘤病情和疗效观察的应用价值与诊断效能。方法 选取2016年3月—2017年12月间在佛山第一人民医院乳腺肿瘤内科住院治疗的女性恶性肿瘤患者149例,早期术后患者(术后组)58例,晚期复发转移患者(晚期组)91例,测定其接受化疗前后的血浆D-二聚体水平(分别记作D1、D2),分析D-二聚体浓度变化(ΔD=D2-D1)与疗效的相关性。D-二聚体浓度(ng/mL)用中位数(四分位间距)表示,治疗前后配对样本比较用Wilcoxon秩和检验,两组间独立+样本比较用Mann-Whitney U检验,以Spearman法分析两组资料的相关性是否有统计学意义。结果 术后组患者化疗后D-二聚体水平低于化疗前(ΔD=-184.8,P<0.0001),D1、D2均与年龄正相关(P<0.01),r²分别为0.356,0.389。晚期组患者中,化疗后有33例出现病情进展(progressive disease, PD组),58例获得疾病缓解或稳定(非PD组)。PD组化疗前基线水平高于非PD组(1 586 vs 754.2,P<0.01),接受化疗后PD组D-二聚体较基线水平升高(ΔD=1 124,P<0.0001),非PD组较基线水平下降(ΔD=-153.3,P=0.004 5),PD组化疗后D-二聚体水平高于非PD组(2 511 vs 525.8,P<0.01)。以ΔD、D1、D2诊断是否PD分别进行受试者工作特征曲线(receiver operating characteristic curve,ROC)分析,结果显示ROC曲线下面积分别为0.8 603(95% CI:0.768 5~0.952 0)、0.674 0(95% CI:0.558 2~0.759 7)、0.895 6(95%CI:0.829 1~0.962 1),对诊断PD有一定准确性。当ΔD＜-145.4 ng/mL、D1>1 375 ng/mL、D2>1 033 ng/mL时,Youden指数最大,诊断PD的准确性较高。结论 血浆D-二聚体的变化与肿瘤负荷密切相关,有助于女性恶性肿瘤病情的判断和疗效观察及评价预后,对辅助判断病情进展上的具有较高的诊断效能。

Objective To investigate the clinical significance and diagnostic value of plasma D-dimer measurement in response evaluation of female patients with tumor. Methods 149 female cancer patients were enrolled, in which there were 58 post-operative early staged cases(post-operative group), 91 metastatic cases(metastatic group). D-dimer levels before chemotherapy (D1) and after the last cycle of chemotherapy (D2) were assessed and analyzed to examine whether they are correlated to response of therapy. D-dimer levels were presented as median(25^th percentile,75^th percentile) and compared using Wilcoxon signed-rank test(for paired samples) and Mann-Whitney U test(for independent samples). Spearman rank tests were conducted to show the correlation of two variables. Results In post-operative group,D2 was lower than D1(ΔD=-184.8,P<0.0001),and both of D1 and D2 were positively correlated with age(r²= 0.356,0.389,respectively,P<0.01). In metastatic group, after chemotherapy,33 cases had progressive diseases(PD group), while 58 cases gained response or stable diseases(non-PD group). Baseline D-dimer level of PD group was higher than that of non-PD group(1586 vs 754.2,P<0.01),and after chemotherapy the case was similar(2511 vs 525.8,P<0.01). After chemotherapy, D-dimer level increased in PD group(ΔD=1124,P<0.0001), and decreased in non-PD group(ΔD=-153.3,P=0.0045).We compared the abilities of the ΔD(ΔD=D2-D1), D1and D2 to discriminate between responders and non-responders using receiver operating characteristic curves(ROC). The areas under the curve (AUC) of the ΔD, D1and D2, were 0.8603(95%CI:0.7685-0.9520)、0.6740(95%CI:0.5582-0.7597)、0.8956(95%CI:0.8291-0.9621), respectively. The appropriate cut-off values with biggest Youden index of D-dimer for non-responders were as follows: ΔD＜-145.4 ng/mL,D1>1375ng/mL,D2>1033ng/mL. Conclusion Plasma D-dimer level is strongly associated with tumor burden. D-dimer could be used to predict prognosis and treatment response in female patients with tumor.
