目的 探讨睫毛蠕形螨感染与睑板腺功能障碍(meibomian gland dysfunction,MGD)发生的相关性,并分析睫毛蠕形螨感染对MGD患者眼表症状跟体征的影响。方法 前瞻性队列研究。选取2018年7月—2019年3月在广州市第一人民医院眼科门诊诊断为MGD患者47例,按照年龄将MGD患者分别纳入MGD＜40岁组(A₁组,28例)和MGD＞60岁组(B₁组,19例)。根据蠕形螨检测结果将MGD患者分别纳入蠕形螨检出阳性组(Ⅰ组,22例)与蠕形螨检出阴性组(Ⅱ组,25例)。同时,选取无MGD正常人或仅患屈光不正、玻璃体混浊的患者共49例,按照年龄将其分别纳入NMGD＜40岁组(A₂组,30例)和NMGD＞60岁组(B₂组,19例)。主要统计受试者眼部症状(眼痒、眼痛、眼干、异物感、视物模糊)发生率、睫毛蠕形螨检出数量及检出率、睑板腺排出能力评分、睑板腺分泌物性状评分及眼表疾病指数(Ocular Surface Disease Index,OSDI)。结果 MGD＜40岁组(A₁组)与NMGD＜40岁组(A₂组)睫毛蠕形螨检出数量分别为(1.14±1.938)、(0.17±0.531)只,差异有统计学意义(P=0.003,＜0.05),睫毛蠕形螨检出阳性率分别为43%、10%,差异有统计学意义(P=0.006,＜0.05);MGD＞60岁组(B₁组)与NMGD＞60岁组(B₂组)睫毛蠕形螨检出数量分别为(1.89±2.331)、(0.68±1.529)只,差异没有统计学意义(P＞0.05),睫毛蠕形螨检出阳性率分别为53%、21%,差异没有统计学意义(P＞0.05); MGD患者睫毛蠕形螨检出阳性组(Ⅰ组)与MGD患者睫毛蠕形螨检出阴性组(Ⅱ组)睑板腺分泌物性状评分分别为(3.00±1.11)、(2.28±1.28),差异有统计学意义(P＝0.047,＜0.05);Ⅰ组OSDI、睑板腺排出能力评分、眼干、眼痛、眼痒、异物感以及视物模糊发生率与Ⅱ组相比,差异均不具有统计学意义(P＞0.05);MGD组文化水平与NMGD组相比,差异没有统计学意义(P=0.382,＞0.05)。结论 首先,在40岁以下人群中,睫毛蠕形螨与MGD形成有一定相关性;而在60岁以上人群中,相较于其他影响因素,睫毛蠕形螨对MGD形成的作用并不显著,表明睫毛蠕形螨对MGD形成的影响主要体现在中青年时期,且随着年龄增长,二者之间的关联性进一步降低。另外,睫毛蠕形螨感染与MGD患者发生眼痛、眼干、眼痒、异物感以及视物模糊这些眼部症状和睑板腺分泌功能受损没有相关性。

Objective To investigate the correlation between eyelash Demodex infection and meibomian gland dysfunction (MGD) and to analyze the effect of eyelash Demodex infection on ocular surface symptoms and signs in patients with MGD. Methods Prospective cohort study. 47 patients with MGD diagnosed in the ophthalmology clinic of Guangzhou First People's Hospital from July 2018 to March 2019 were selected. The MGD patients were assigned to the MGD＜40 years old group (A₁ group, n=28) and MGD＞60 years old Group (B₁ group, n=19) according to the age. According to the Demodex test results, MGD patients were assigned to the Demodex-positive group (I group, n=22) and the Demodex-negative group (II group, n=25). At the same time, 49 patients without MGD or only with ametropia and vitreous opacity were selected and assigned to the NMGD＜40 years old group (A₂ group, n=30) and NMGD＞60 years old group (B₂ group, n=19) according to their age. The incidence of ocular symptoms (itchiness, pain, dryness, foreign body perception, and blurred vision), the number and rate of detection of eyelash Demodex, meibomian gland ejection score, meibomian gland secretion score, and Ocular Surface Disease Index (OSDI) were analyzed. Results The number of eyelash Demodex was (1.14±1.938) in MGD＜40 years old group (A₁ group) and (0.17±0.531) in NMGD＜40 years old group (A₂ group). The difference in the number of eyelash Demodex between these two groups was found to be statistically significant (P=0.003,＜0.05). The positive rate of eyelash Demodex was 43 % in MGD＜40 years old group (A1 group) and 10% in NMGD＜40 years old group (A₂ group). The difference in the positive rate of eyelash Demodex between these two groups was found to be statistically significant (P=0.006,＜0.05). The number of eyelash Demodex in MGD＞60 years old group (B₁ group) was (1.89±2.331) and in NMGD＞60 years old group (B₂ group) was (0.68±1.529). The difference in the number of eyelash Demodex between these two groups was not statistically significant(P>0.05). The positive rate of eyelash Demodex was 53 % in MGD＞60 years old group (A₁ group) and 21% in NMGD＞60 years old group (A₂ group). The difference in the positive rate of eyelash Demodex between these two groups was not statistically significant (P>0.05). The score of the meibomian gland secretion in the MGD with eyelash Demodex group (I Group) was (3.00±1.11) and in the MGD without eyelash Demodex group (II group) was (2.28±1.28). The difference in the score of the meibomian gland secretion between these two groups was found to be statistically significant (P=0.047<0.05). The differences of the OSDI score, the meibomian gland discharge ability score, the incidence rate of dry eye, eye pain, eye itching, foreign body sensation and blurred vision between these two groups were not statistically significant (P>0.05). The difference in the culture level between the MGD group and the NMGD group was not statistically significant (P=0.382, >0.05). Conclusion First, in the population under 40 years old, eyelash Demodex is correlated with MGD. Then in the population over 60 years old, the effect of eyelash Demodex on the formation of MGD compared with other influencing factors is not significant. The results indicated that the effect of eyelash Demodex was mainly reflected in the middle and young age, and the correlation between them was further reduced with the increase of age. In addition, in MGD patients, eyelash Demodex infection was not significantly correlated with the incidence of eye pain, eye dryness, eye itching, foreign body sensation, and blurred vision, as well as the degree of impairment of meibomian gland secretion function.

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 本研究的目的在于通过非孕期与孕期妇女行胎儿纤维连接蛋白的检测对比,再次认识胎儿纤维连接蛋白在早产预测中的价值,是否能有效的预测早产。方法 通过对180例非孕妇女行fFN检测,同时进行白带感染方面的检测,从而判断两者是否具有相关性,同时通过对150例中晚孕妇女于20～34周行fFN检测,判断其在预测早产发生方面的临床应用价值。结果 在180例非孕妇女,发生生殖道感染的患者fFN阳性率增高,与fFN阴性者有差异;在150例中晚孕妇女当中,患者于7天内分娩的敏感度,特异度,阳性预测价值,阴性预测价值为85.7%,69.33%,13.33%,99%。14天内分娩的敏感度,特异度,阳性预测价值,阴性预测价值为80％,68.67%,17.78%,99%。结论 由于 fFN检测易受生殖道感染及其他多种因素干扰,故其在早产预测中的准确性有限。

Objective To explore the significance of C-reactive protein (CRP), procalcitonin (PCT), neutrophil count (NC) and neutrophil / lymphocyte ratio (NLR) in the early diagnosis of bacterial infection in lung cancer patients after chemotherapy. Methods From January 2019 to December 2019, 78 cases of lung cancer patients with bacterial infection after chemotherapy, 64 cases of uninfected patients after chemotherapy and 39 cases of healthy people in the same period were collected. the contents of PCT and CRP in serum were detected by solid phase immunosorbent assay and rate nephelometry.The NC and NLR were classified and counted by mindray cal8000 hematology analyzer. Results After chemotherapy, CRP, PCT, NC and NLR in the infected group were higher than those in the uninfected group and the healthy control group (P<0.01), while CRP, PCT, NC and NLR in the uninfected group were higher than those in the healthy control group (P<0.01). When CRP, PCT, NC and NLR were used together, the sensitivity was 97.507%, while the specificity increased by 97.15%. The PCT, CRP, NC and NLR of patients with bacterial infection before treatment were lower than those after treatment (P<0.05). Conclusion PCT, CRP, NC and NLR may improve the sensitivity and specificity of early diagnosis of bacterial infection in patients with lung cancer after chemotherapy.

Objective To explore the influencing factors of infection in elderly patients with intravenous infusion port. Methods 72 elderly patients from May 2015 to August 2018 were randomly selected in our hospital. After counting the number of patients with complicated infection,the relative factors of infection in elderly patients were analyzed by using the Logistic regression equation. Results A total of 72 patients were included in the intravenous infusion port with concurrent infection,of which 23 were accompanied with infection,accounting for 31.94%.By comparing the general data,two groups in puncture sites,types of diseases,application times and frequencies,histories of diabetes and body masses had statistically difference(P<0.05). It was found all the above factors were the concomitant factors leading to the implantation of intravenous infusion port in elderly patients by putting the difference data into the Logistic regression equation. Conclusion To control infusion port related infection,the elderly patients should focus more on the infection factors of the implantation in intravenous infusion port which included puncture sites,types of diseases,application times and frequencies,histories of diabetes and body masses.
