With the growing popularity of periocular cosmetic procedures, including injectable fillers, laser therapy, and eyeliner tattooing, the incidence of meibomian gland dysfunction(MGD)and other meibomian gland disorders has increased correspondingly. Nevertheless, the standardized diagnosis and management of these conditions remain controversial. Based on multidisciplinary clinical practice and up-to-date evidence-based medical evidence, this expert consensus systematically elaborates on the pathogenesis, clinical manifestations, and diagnostic criteria of cosmetic procedure-related MGD. It highlights the necessity of detailed medical history collection and comprehensive ocular surface assessment. A stepwise therapeutic strategy, covering conservative nursing management, pharmacological intervention, and physical therapy, is proposed for standardized clinical treatment. In addition, this consensus standardizes the preoperative evaluation workflow for periocular cosmetic procedures, optimizes operational techniques to prevent meibomian gland injury, and stresses the significance of standardized postoperative follow-up for reducing iatrogenic ocular complications. This consensus intends to improve clinicians'cognition and standardized management of periocular cosmetic procedure-related MGD, and facilitate a benign balance between cosmetic procedural safety and ocular surface health.

Objective:To investigate the preventive and therapeutic effects of compound wild chrysanthemum eye pad on blue light-induced alteration of meibomian gland function in mice and its mechanism.Methods:Sixty-four 15-week-old male C57BL/6J mice were divided into two groups of 32 mice each according to random numbers for the prevention test and the treatment test.The respective 32 mice in the prevention and treatment experiments were randomly divided into normal group, blue light group, solvent group and eye pad group according to random numbers, with eight mice in each group, respectively.In the prevention experiments, mice in each group were exposed to blue light at a wavelength of 460 nm and a light intensity of 2 000 lx for 6 hours per day for 15 consecutive days to establish a mouse model of meibomian gland function changes except for the normal group.The solvent group and the eye pad group were treated with the corresponding eye pad before and after the blue light exposure for 25 minutes daily for the 15 consecutive days.The blue light group was treated with blue light exposure only for 15 days, and the mice were photographed at the edge of the meibomian gland on day 15 to observe the function of the meibomian gland except for the normal group.In the treatment test, all groups of mice except the normal group were induced the altered function of the mouse meibomian gland by the above method.The solvent and eye pad groups were treated with corresponding eye pads for 25 minutes in the morning and afternoon of each day for 15 consecutive days after blue light exposure.The blue light group was kept in a standard environment for 15 days and the changes in meibomian gland function of mice were detected by meibomian gland photographs on day 15.Photography of the eyelid margin in vitro, oil red O staining, and hematoxylin-eosin staining were performed to observe the histologic changes in the meibomian glands of mice after the preventive and experimental treatment.The relative expression of interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ) mRNA in mouse meibomian gland tissues was detected by real-time fluorescence quantitative PCR.The expression of nuclear factor-κB (NF-κB) and phosphorylation of NF-κB (p-NF-κB) proteins in mice meibomian gland tissues was detected by Western blot to assess the degree of amelioration of blue light-induced inflammation in mouse meibomian glands by the compound wild chrysanthemum eye pad.This study was conducted in accordance with the Statement of the Association for Research in Vision and Ophthalmology on the Use of Animals in Ophthalmology and Vision Research, and was approved by the Animal Ethics Committee of Xiamen University (No.XMULAC20220258). Results:Compared with the normal group, a gradually increased number of blocked meibomian gland openings, and a gradually decreased remaining area of lower meibomian gland, were observed in the mice after 15 days of blue light group, and all the differences were statistically different (all at P<0.05). In the prevention test, the number of obstructed opening in the eye pad group was 1.833±0.753, which was significantly less than 3.667±1.033 in the solvent group ( P<0.05). The relative remaining area of the lower lid meibomian gland in the eye pad group was 0.718±0.091, which was significantly greater than 0.624±0.130 in the solvent group ( P<0.05). Hematoxylin-eosin staining showed inflammatory cell infiltration in mouse meibomian gland in the blue light and solvent groups.There was no inflammatory cell infiltration in eye pad group, and the morphology of the acini was similar to that of the normal group.Oil red O staining showed that there was no significant lipid deposition in the groups.The relative expressions of IL-1β, IL-6, TNF-α, and IFN-γ mRNA were significantly lower, and the relative expressions of NF-κB and p-NF-κB proteins were significantly lower in the eye pad group than in the solvent group, showing statistically significant differences (all at P<0.05). In the treatment test, the number of obstructed openings in the eye pad group and solvent group was 4.333±1.211 and 4.833±1.722, respectively, and the relative remaining area of the lower meibomian gland was 0.572±0.151 and 0.588±0.154, respectively, showing no statistically significant differences (both at P>0.05). Hematoxylin-eosin staining showed inflammatory cell infiltration in mouse meibomian glands in the blue light and solvent groups, with a similar morphology of acini as in the normal group.There was no inflammatory cell infiltration in eye pad group.Oil red O staining showed that there was no significant lipid deposition in the groups.The relative expressions of IL-1β, IL-6, and IFN-γ mRNA were significantly lower and the relative expressions of NF-κB and p-NF-κB proteins were significantly lower in the eye pad group than in the solvent group (all at P<0.05). Conclusions:Compound wild chrysanthemum eye pad may have preventive and therapeutic effects on blue light-induced changes in meibomian gland function by reducing the inflammatory response of meibomian gland tissue through the inhibition of the NF-κB signaling pathway.

Objective:To explore the prediction model of tissue chip technology for the chemotherapy response of patients with colorectal cancer.Methods:217 patients with colorectal cancer who had received standardized chemotherapy in the Affiliated People’s Hospital of Ningbo University from Jan. 2017 to Dec. 2019 were prospectively selected. The patients were randomly divided into training set (152 cases) and test set (65 cases) according to the ratio of 7:3, and were followed up for 6 months. The clinical data of the patients in the training set were compared, the expression levels of Ang-2, caspase-3 and CD147 in the patients were analyzed by tissue microarray technology, and the related factors affecting the responsiveness of colorectal cancer chemotherapy were analyzed by the Logistic regression model. R software was used based on the training set. A nomogram prediction model was built and model performance on the test set was evaluated.Results:One case was excluded from the training center, and 151 cases were finally included, including 93 cases in the chemotherapy response group and 58 cases in the chemotherapy response group. The tumor diameter, serum carcinoembryonic antigen, caspase3, Ang2 expression level, and the proportion of clinical stage IV in the poor chemotherapy group were significantly higher than those in the good chemotherapy group (all P<0.05) ; Logistic regression showed tumor diameter ( OR=2.394), serum carcinoembryonic antigen ( OR=1.878), caspase-3 ( OR=4.261), Ang-2 expression level ( OR=5.457), and clinical stage IV ( OR=5.954) were independent risk factors for adverse drug reactions in patients with colorectal cancer (all P<0.05). The consistency index (C-index) for predicting the factors related to adverse chemotherapy reactions in patients with colorectal cancer was 0.915. External verification showed that the sensitivity was 86.96%, the specificity was 92.50%, and the accuracy was 90.48% (42/65) . Conclusion:The expression levels of Ang-2 and caspase-3 are correlated with the responsiveness of colorectal cancer to chemotherapy, and can be used as predictive indicators to evaluate the responsiveness of colorectal cancer to chemotherapy.

Objective:To investigate the expressions of MUC1, MUC4, MUC5AC and MUC16 in patients with first diagnosis of dry eye and their correlation with dry eye symptoms and signs.Methods:A cross-sectional study was conducted.Sixty-nine dry eye patients (69 eyes) as dry eye group and 40 normal volunteers (40 eyes) as normal control group were recruited in Xiamen Eye Center of Xiamen University, Beijing Tongren Hospital, West China Hospital of Sichuan University and Shanghai Puotuo District Center Hospital from December 2016 to May 2018.Symptoms were evaluated by Chinese dry eye questionnaire, Ocular Surface Disease Index (OSDI) and Dry Eye-Related Quality-of-Life Score Questionnaire (DEQS). Signs were assessed by tear film breakup time (TBUT), keratoconjunctival fluorescein sodium staining, and Schirmer I test.Conjunctival cells were collected by conjunctival impression cytology.The expression levels of MUC1, MUC4, MUC5AC and MUC16 mRNA in the two groups were determined by real-time fluorescence quantitative PCR.The correlation between the mRNA levels of conjunctival mucins and dry eye symptoms and signs were analyzed by Spearman correlation analysis.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committees of Xiamen Eye Center of Xiamen University (No.2017003), Beijing Tongren Hospital, Capital Medical University (No.TREC2016-29), West China Hospital of Sichuan University (No.2016310) and Shanghai Puotuo District Center Hospital (No.PTEC-A-2016-18-1). Written informed consent was obtained from each subject before any medical examination.Results:The expression levels of MUC1 and MUC16 mRNA in dry eye patients were 3.277(0.568, 5.790) and 1.815(1.048, 3.694), which were higher than 1.055(0.550, 2.010) and 1.024(0.541, 1.965) in normal control group (Z=819.00, P=0.008; Z=861.00, P=0.002). According to OSDI scores, MUC1 was mainly increased to 3.277(1.161, 6.226) in mild to moderate (12-32 points) dry eye patients (Z=9.04, P=0.029), and MUC16 was mainly increased to 1.968(1.074, 3.726) in severe (>32 points) dry eye patients (Z=12.24, P=0.007). MUC1 expression was positively correlated with TBUT, and was negatively correlated with corneal staining scoring and keratoconjunctival staining scoring ( r s=0.270, P=0.025; r s=-0.331, P=0.006; r s=-0.325, P=0.007). MUC16 expression was positively correlated with TBUT, and was negatively correlated with blurred vision scoring, symptom exacerbation scoring during reading, impact scoring of driving at night, impact scoring of computer and impact scoring of TV use ( r s=0.249, P=0.039; r s=-0.359, P=0.047; r s=-0.370, P=0.034; r s=-0.558, P=0.016; r s=-0.498, P=0.006; rs=-0.515, P=0.002).

Meibomian gland dysfunction (MGD) is a chronic, diffuse meibomian gland disorder, which has complex pathogenesis and high prevalence.It has become one of the common ocular surface diseases in clinics, and its treatment has been the clinical research focus and a challenge over the years.The traditional treatments consist of lifestyle improvement, physical therapy, medical treatments and surgery, in which drug plays an important role.According to the etiology and pathogenesis of MGD, the applied drugs can be classified into three categories.The first category is to improve the quality of tears and the stability of tear film, including artificial tear and ocular surface lubricants, secretagogues (promoting the secretion of lipids, aqueous solution and mucin), androgens, etc.The second category is to improve the ocular surface microenvironment, including local and systemic antibiotics, glucocorticoid eyedrops, non-steroidal anti-inflammatory drugs, immunosuppressants, anti-mites drugs, etc.The third category is nutritional supplements and neuroprotectants, including vitamin D3, omega-3 fatty acids, autologous serum and so on.This review focused on widely-used and current emerging treatment options, aiming to provide references for clinical treatments and further study on MGD.

Objective:To analyze the clinical manifestations and signs of the first diagnosed dry eye patients, and to explore the concordance between the Chinese dry eye diagnostic criteria and the Asian dry eye diagnostic criteria.Methods:A cross-sectional multicenter study was conducted.One hundred and forty-one eyes of 141 patients who were diagnosed as dry eye for the first time were included in Xiamen Eye Center of Xiamen University, Beijing Tongren Hospital, West China Hospital of Sichuan University and Shanghai Putuo District Center Hospital from December 2016 to May 2018.All patients completed the Chinese Dry Eye Questionnaire, Ocular Surface Disease Index (OSDI) and Dry Eye-Related Quality-of-life Score Questionnaire (DEQS) to evaluate the symptoms of dry eye.Tear film breakup time (BUT), keratoconjunctival fluorescein staining, meibomian gland morphology and function examination, and Schirmer Ⅰ test were performed to evaluate dry eye signs and the association between dry eye symptoms and signs.The eyes were divided into corneal staining positive and negative group according to the presence or absence of corneal fluorescein staining, and the dry eye symptoms of the two groups were assessed by the three questionnaires.The eyes were divided into tear-deficient dry eye, evaporative dry eye, mixed dry eye and abnormal tear dynamics dry eye to compare the difference of dry eye signs among the groups.This study adhered to the Declaration of Helsinki.The study protocol complied with Chinese regulations and rules on clinical trial research and was approved by Ethics Committees of Xiamen Eye Center of Xiamen University (No.2017003), Beijing Tongren Hospital, Capital Medical University (No.TREC2016-29), West China Hospital of Sichuan University (No.2016310) and Shanghai Putuo District Center Hospital (No.PTEC-A-2016-18-1). Written informed consent was obtained from patients before entering the cohort.Results:The total score of Chinese Dry Eye Questionnaire, OSDI questionnaire and DEQS questionnaire was 12.00(7.00, 16.00), 25.00(17.50, 36.93) and 32.02(15.77, 52.34), respectively.It was found that 130 eyes (92.2%) had dryness, and 109 eyes (77.3%) had ocular fatigue and 108 eyes (76.6%) had foreign body sensation.Dryness, foreign body sensation, photophobia and poor vision were weakly positively correlated with corneal staining ( r=0.177、0.297、0.172, all at P<0.05). Pain, photophobia and poor vision were negatively correlated with tear secretion ( r=-0.178, -0.197, -0.174; all at P<0.05). It was found that 43.3% of dry eye patients had used visual display terminals.Among the 141 eyes, 75 eyes (53.2%) were with over evaporation dry eye, 43 eyes (30.5%) with mixed dry eye, 18 eyes (12.8%) with aqueous-deficient dry eye and 3 eyes (2.1%) with abnormal tear dynamics dry eyes. Conclusions:Initial diagnosis of dry eye patients is mainly mild to moderate.Dry eye signs and symptoms are correlated.Over evaporation dry eye is the most common type of dry eye.The concordance between the Chinese dry eye diagnostic criteria and the Asian Dry Eye Society diagnostic criteria reaches 97.2%.

An expert consensus about the clinical diagnosis and treatment of dry eye was documented in 2013 by a corneal expert group of Chinese Ophthalmological Society.However, due to the rapid development of diagnostic and therapeutic devices of dry eye, researoh on dry eye has made significont progress in China since then.Consequently, the existing expert consensus cannot meet the needs of clinical practice.It is therefore urgent to develop a series of standardized diagnosis and treatment protocols, and publish a new consensus of experts and an operating guideline.At the same time, basic, clinical, and translational research on dry eye should be promoted to provide better services to the patients with dry eyes.On January 12, 2019 many experts in the field of dry eye in China held a panel discussion of dry eye study in Guangzhou to analyze the current development status and trends in the field of dry eye in China and abroad.In that meeting, opinions and recommendations were put forward based on a new understanding of the definition of dry eye, new concepts of dysfunctional dry eye, advances its diagnosis and classification, refinement and standardization of dry eye treatment, and the future development of dry eye research.

Accumulating studies have recently shown that long noncoding RNAs (lncRNAs) are involved in the initiation and progression of myocardial fibrosis,a common histological characteristic of heart conditions and prominent global health issues. LncRNAs are prominently served as regulatory molecules via interaction with DNA,RNA and proteins in transcriptional and post-transcriptional processes. They can change morphological structure and biochemical metabolism of cardiac cells and regulate homeostasis of the cardiac extracellular matrix. Therefore,lncRNAs show great potential as diagnostic and prognostic biomarkers and therapeutic targets for anti-fibrotic treatment.
