糖尿病已成为全球最严重的健康问题之一。需要白内障手术的糖尿病患者也日益增多,虽然糖尿病的眼表并发症很常见,但由于糖尿病患者全身和眼部疾病十分复杂,使得眼前段如角结膜和泪腺的糖尿病并发症往往被忽视。糖尿病患者白内障超声乳化术有引发或加重眼前节疾病的风险,包括干眼病（DED）、角膜上皮糜烂、上皮缺损迁延不愈,甚至威胁视力的角膜溃疡。这些风险里最为常见的是DED,并且可能因白内障超声乳化手术而加重。眼科医生需要在手术前预先评估已存在的DED是否需要术前治疗,并且需要注意在已存在 DED 的情况下,各项术前检查数据测量的准确性会降低,以及尽可能减少对眼表造成损害的各种手术因素;并考虑通过管理减少术后 DED。本综述就评估白内障超声乳化术对合并糖尿病的老年性白内障患者的眼表术中的影响因素进行分析。

Diabetes mellitus(DM)has become one of the most serious health problems in the world. The number of diabetic patients requiring cataract surgery is also increasing. Although ocular surface complications of DM are common,the complexity of systemic and ocular disease in diabetic patients makes diabetic complications in the anterior segment,such as the cornea and lacrimal gland,often be overlooked. Phacoemulsification in diabetic patients carries the risk of triggering or exacerbating ocular segment disease,including dry eye disease,corneal epithelial erosion,persistent epithelial defects and even vision-threatening corneal ulcers. The most common of these risks is dry eye disease,and it can be exacerbated by cataract phacoemulsification. Ophthalmologists need to preemptively assess the need for preoperative treatment of pre-existing dry eye disease(DED),be aware of the reduced accuracy of preoperative data measurements in the presence of DED,and minimize surgical factors that can damage the ocular surface;and consider management to reduce postoperative DED. In this review,we analyze the factors that influence phacoemulsification in ocular surface surgery for senile cataract patients with diabetes.

代谢综合征属于中医学“肥胖”“消渴”“脾瘅”等范畴,是以多种代谢异常在同一个体集结出现,包括肥胖、高血糖、血脂异常、高血压以及高尿酸血症等为表现的临床综合征。“浊毒”是由于脏腑功能失常,导致机体产生的生理、病理产物不能及时排出,蕴积体内而化生的致病因素。浊毒致病机体多有面色晦浊、腹胀满、小便浑浊、大便黏腻不爽、黄腻苔、滑数脉等表现。浊毒与代谢综合征的发病机制,在微观和宏观上具有对应性。文章从浊毒与代谢综合征的发病机制出发,对其临床治疗的共同点进行了综述。

Metabolic syndrome falls into the categories of obesity,diabetes and spleen disease in traditional Chinese medicine,and is manifested by various metabolic abnormalities in an individual,including obesity,hyperglycemia,dyslipidemia,hypertension and hyperuricemia. The turbid toxin is a pathogenic factor caused by visceral dysfunction,which leads to the accumulation of physiological and pathological wastes that fail to be eliminated from the body in time. People with turbid toxin are manifested by dull and cloudy complexion,abdominal distension,turbid urine,sticky stool,yellow greasy coating,slippery pulse,etc. The turbid toxin corresponds to the pathogenesis of metabolic syndrome at both micro and macro levels. This paper intends to explore the correlations between the turbid toxin and the pathogenesis of metabolic syndrome and make a review with relevant clinical treatment.

Objective To explore the value of detecting exhaled nitric oxide(FeNO)during systemic glucocorticoid use in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). Methods A randomized controlled study was conducted from January 2019 to December 2021 at the People's Hospital of Meizhou City. The subjects were 58 AECOPD patients,all of whom were tested for FeNO levels. Based on whether the FeNO levels were>25 ppb,they were divided into a high level FeNO group and a low level FeNO group. They were divided into a treatment group and a control group based on whether they received systemic glucocorticoid therapy. The control group received routine treatment,while the treatment group received routine and systemic glucocorticoid therapy. Changes in FeNO and lung function indicators before and after treatment were detected,COPD assessment test(CAT)scores were determined,and differences between groups were compared. Results After systemic glucocorticoid therapy,the high level group of FeNO showed a decrease in FeNO(P<0. 05),while the high level group showed no statistically significant difference in FeNO before and after routine treatment(P>0. 05). The low level group showed no statistically significant difference in FeNO between the treatment group and the control group before and after treatment(P>0. 05). The first second forced expiratory volume(FEV₁)and the ratio of first second forced expiratory volume to forced vital capacity(FEV₁/FVC)in the high level group of FeNO significantly increased after treatment,and the degree of increase in the treatment group was greater than that in the control group(all P<0. 05). The FEV₁ and FEV₁/FVC in low level group of FeNO significantly increased after treatment(all P<0. 05),but the difference between the treatment group and the control group was not significant(P>0. 05). The CAT scores of the high and low levels of FeNO groups decreased after treatment compared to before treatment(all P<0. 05),and the decrease was more significant in the high level FeNO group. Conclusions The implementation of FeNO measurement in AECOPD patients can reflect airway inflammation to a certain extent,predict glucocorticoid treatment response,guide the rational and effective application of systemic glucocorticoid and avoid excessive glucocorticoid use.

Objective To explore and study the correlation between interleukin-33(IL-33),interleukin-37(IL-37),leucine-enriched nucleotide-binding oligomeric domain(NLRP)- 3,the ratio of natural killer(NK)cells/dendritic cells(DC)and the conditions of patients with chronic hepatitis B(CHB). Methods From February 2020 to September 2022,86 patients with CHB treated in our hospital were selected as hepatitis group,and 86 healthy patients were selected as control group during the same period. The contents of IL-37,IL-33 and NLRP3 in serum of the two groups were detected,and NK/DC ratio was calculated. Serum alanine aminotransferase(ALT),aspartate aminotransferase(AST)and total bilirubin(TBIL)of all the selected subjects were detected and correlation analysis was carried out. Results Compared with the control group,the serum ALT,TBIL and AST in hepatitis group were significantly increased(P<0. 05),the contents of IL-33,IL-37 and NLRP3 were higher(P<0. 05),and the NK/DC ratio was significantly decreased(P<0. 05). In the hepatitis group,Pearson analysis showed that IL-33,IL-37,NLRP3 and NK/DC ratios were correlated with ALT,TBIL and AST(P<0. 05). In the hepatitis group,ROC curve analysis showed that the maximum areas under the curve of IL-33,IL-37,NLRP3 and NK/DC ratios were 0. 705(95%CI：0. 404-1. 123),0. 690(95%CI：0. 372-1. 057),0. 670(95%CI：0. 378-1. 043)and 0. 685(95%CI：0. 415-1. 107),and the maximum area under the curve of combined detection was 0. 895(95%CI：0. 532-1. 216). Compared with single detection,combined detection had higher specificity and sensitivity. Conclusions The patients with CHB are often accompanied by the high expression of serum IL-33,IL-37 and NLRP3,and the NK/DC ratio will be significantly reduced. IL-33,IL-37,NLRP3 and NK/DC ratio are correlated with the condition of patients with CHB,and can also predict the condition of patients.
