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.

Methods Thirty-four patients with clinically confirmed stroke (stroke group) in our hospital were collected as the research object. Another 56 patients with carotid plaque but without stroke (control group) in the same period were selected as the control object for ultrasonic elastography detection, and the results were analyzed statistically. Results Thirty-four stroke patients were found 57 carotid atherosclerotic plaques, including 29 hypoechoic plaques, 21 mixed echoic plaques and 7 hyperechoic plaques; 56 control patients were found 75 carotid atherosclerotic plaques, including 22 hypoechoic plaques, 25 mixed echoic plaques and 28 hyperechoic plaques. There were significant differences between the number of plaques and the size of plaques (P<0.05). Carotid atherosclerosis low echo, mixed echo and strong echo plaque elasticity score increased in turn, the plaque hardness value increased in turn; the number of plaque scores between the two groups had statistical significance (P<0.05); for the same type of plaque hardness value between the two groups had no significant difference (P>0.05); There were significant differences in hardness values between the same types of plaques (P<0.05). Conclusion Ultrasound elastography may semi-quantitatively evaluate the stability of carotid atherosclerotic plaques in stroke patients. Different types of plaques have different elastic strain rates because of different tissue components. It may effectively complement the information deficiency of conventional ultrasound examination, and then evaluate the stability of plaques.

目的 分析比较总额控制下的病种分值付费和单病种付费支付方式的应用效果。方法 回顾性分析2015年—2018年总额控制下病种分值付费和单病种付费模式下的平均住院费用、医保基金支出以及医保基金收入等基本情况,比对分析总额控制下单病种付费模式下与病种分值付费模式的总体运行效率。结果 2015年—2018年总额控制下病种分值付费情况存在轻微波动,但不出现明显上涨现象,稳定于9 000元左右的水平,并且总额控制下病种分值付费的医保基金结余率处于17%的水平,同时具有稳定的医保基金支出与医保基金收入水平。相比较总额控制下病种分值付费,单病种付费模式下的平均住院费用更高,且呈现出逐年增加的发展趋势;相比较2015年的平均住院费用,2018年平均住院费用高出500元。2015年—2018年总额控制下单病种付费的医保基金结余率具有较大波动,表示医保基金支出与医保基金收入水平不稳定。结论 总额控制下的病种分值付费模式具有明显的医疗费用以及医保基金费用支出控制效果,但同时也具有较大的基础投入水平以及较高管理成本等缺陷端,总额控制下的单病种付费模式具有方便管理的优势,但是在费用控制、病种涵盖等方面不如病种分值付费,总额控制下的单病种付费与病种分值付费各具优势和不足,需要依据区域情况,取长补短,因地制宜以及择优而用,确保健全医保支付方式。

Objective To analyze the application effect of the payment of disease type and the payment of single disease payment under the control of total amount. Methods A retrospective analysis of the basic hospitalization expenses, medical insurance fund expenditures and medical insurance fund income under the control of the total value of the disease and the single-income payment model under the total control from 2015 to 2018 were taken, and to have comparative analysis of the total control of the single disease overall operational efficiency of the payment model with the payment model. Results There was a slight fluctuation in the payment of disease value under the control of total amount from 2015 to 2018, but there was no obvious increase, which was stable at around 9 000 yuan, and the balance of medical insurance fund paid for the disease value under the total control was at 17% level and has both stable medical insurance fund expenditure and medical insurance fund income level. Compared with the total score control under the total amount control, the average hospitalization cost under the single disease payment mode was higher, and showed a trend of increasing year by year; compared with the average hospitalization cost in 2015, the average hospitalization cost in 2018 was higher, out of 500 yuan. From 2015 to 2018, the balance of the medical insurance fund paid for the control of the single disease had a large fluctuation, indicating that the medical insurance fund expenditure and the medical insurance fund income level were unstable. Conclusion The disease-based payment model under total control has obvious control effect of medical expenses and medical insurance fund expenses, but it also has a large basic input level and high management cost and other defects. The payment model has the advantage of convenient management, but it is not as good as the cost control and disease coverage, and the single disease payment and the disease value payment under the total control have their own advantages and disadvantages, which need to be based on the regional situation. We need to make use of the strengths and weaknesses, adapt to local conditions and choose the best, to ensure a sound medical insurance payment method.

Objective To investigate the clinical features of infantile allergic proctocolitis and its endoscopic lesions and pathological features. Methods A retrospective analysis of 110 cases of infantile allergic proctocolitis admitted to our hospital from January 2016 to December 2018 and its colonoscopy and pathological results, food allergen-specific IgG, blood routine, fecal routine, serum total IgE detection and treatment. Results Among 110 patients with allergic proctocolitis, 67 were male and 43 were female, 98 were < 6 months old; 26 were breastfed exclusively, 19 were fed milk alone, and 65 were mixed feeding. The clinical manifestations were diarrhea, most of children with bloody stools (93 cases), some children with eczema (23 cases), defecation and crying (67 cases), restless sleep (61 cases), vomiting (8 cases), malnutrition (6 cases); blood eosinophils increased in 63 cases,serum total IgE increased in 21 cases. Food allergen-specific IgG test results:103 cases of milk, 62 cases of eggs. Endoscopic lesions involved the descending colon, sigmoid colon, rectum, 76 cases of transverse colon, 47 cases of ascending colon and 18 cases of ileocecal. Most common manifested as herpes-like changes (106 cases), erosion (97 cases), ulcers (13 cases). Histopathology showed 91 cases of intestinal mucosal eosinophil infiltration, 21 cases of cryptitis and crypt hyperplasia, 18 cases of lymphoid follicle formation and 4 cases of superficial ulcer formation. 18 cases were improved after the mother evaded diet. 8 cases were improved by feding with amino acid milk powder for one week, and then breast milk was gradually introduced; 19 cases were improved after switching to deep hydrolysis or amino acid milk powder. 65 cases were improved after switching to deep hydrolysis or amino acid milk powder and simultaneously the mother evaded diet. Conclusion Infantile allergic proctocolitis lack of insufficient specific manifestations, most of the clinical cases are good, only a few are complicated by malnutrition. Milk is the most important allergen. Diarrhea, history of blood in the stool, elevated blood eosinophils, intestinal herpes-like changes, bowel mucosal eosinophil infiltration, are suggesting a high possibility of allergic proctocolitis. Mothers avoiding diet or switching to amino acids or deep hydrolyzed milk powder treatment is also effective, and this is also the standard of diagnosis of proctocolitis.
