Objective:To evaluate the efficacy and safety of a China original liquid pulsation system for the treatment of meibomian gland dysfunction (MGD).Methods:A non-randomized controlled clinical trial was conducted.Twenty-two patients (44 eyes) diagnosed with MGD in Eye and ENT Hospital of Fudan University from February to August 2022 were enrolled.The patients were assigned into two groups according to their willingness.Of the 22 patients (44 eyes), 10 patients (20 eyes) in single liquid pulsation system group were treated with single liquid pulsation system for 12 minutes, and 12 patients (24 eyes) in intense pulsed light (IPL) group were treated with a course (4 times) of IPL, warm compresses and meibomian gland massage at three-week intervals.There was no difference in age and other baseline clinical indexes between the two groups (all at P<0.05). The meibum grading, quality grading of tear film lipid layer, Symptom Assessment Questionnaire in Dry Eye (SANDE) questionnaire score, first and average tear breakup time (BUT), corneal fluorescein sodium staining (CFS) score, tear meniscus height (TMH), and the area of meibomian gland loss were determined at baseline, 1 and 3 months after treatment.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Eye and ENT Hospital of Fudan University (No.2021069). Written informed consent was obtained from each patient before any medical examination. Results:Statistically significant group effects and time effects were found in the quality of tear film lipid layer ( Hgroup=4.39, P=0.036, Htime=6.30, P=0.043) and average BUT ( Fgroup=4.41, P=0.038; Ftime=4.08, P=0.049) in the two groups.The meibum grading, first BUT and TMH 1 and 3 months after treatment were significantly better than before treatment in single liquid pulsation system group (all at P<0.05). Compared with before treatment, there was no significant improvement in the meibum grading, distribution of tear film lipid, first BUT and TMH at 1 and 3 months after treatment in IPL group (all at P>0.05). In both groups, the SANDE and CFS scores 1 and 3 months after treatment were better than those before treatment, showing statistically significance (all at P<0.05). In terms of safety, neither instrument-related adverse events nor extra complaints of discomfort were reported in the single liquid pulsation system group.In both groups, the number of patients with positive CFS staining significantly decreased, and no new cases with positive CFS appeared after treatment. Conclusions:This China original liquid pulsation system is a safe and effective physical therapy in improving tear film dysfunction and ocular surface symptoms of MGD patients within 3 months after treatment.

Objective:To evaluate the effect of pre-injection of young rat plasma on cognitive dysfunction after cerebral ischemia-reperfusion (I/R) in aged rats and the role of phosphatidylinositol 3-kinase/serine threonine protein kinase (PI3K/Akt) signaling pathway.Methods:Seventy-two SPF-grade healthy male Sprague-Dawley rats, aged 18 months, weighing 600-650 g, were divided into 4 groups ( n=18 each) by the random number table method: control group (group C), cerebral I/R group (group IR), pre-injection of young rat plasma group (group P) and PI3K inhibitor LY294002 group (group LY). In group P and group LY, young rat plasma 100 μl/time was injected via the tail vein. In group C and group IR, the equal volume of normal saline was injected via the the tail vein, 2 times a week for 4 weeks. Then the model of cerebral I/R injury was developed under sevoflurane anesthesia in IR, P and LY groups. LY294002 0.3 mg/kg was injected through the tail vein at 1 h before anesthesia in LY group. The neurological deficit score (Longa score) was performed at 24 h after reperfusion, and then 6 rats were randomly sacrificed, and brain tissues were obtained to determine the cerebral infarct volume. Spontaneous mobility and anxiety-like behavior were assessed by the open field test at day 29 of reperfusion, and cognitive function was assessed by the novel object recognition test at day 30 of reperfusion. At the end of the behavioral test, rats were sacrificed, hippocampal tissues were isolated for determination of the expression of phosphorylated PI3K (p-PI3K), phosphorylated Akt (p-Akt), postsynaptic dense protein-95 (PSD-95) and synaptic vesicle protein (SYN) (by Western blot), and the dendritic length and dendritic spine density of neurons in the hippocampal CA1 region. Results:There was no significant difference in motor speed, distance traveled, and time of staying at the center of the open field among the four groups ( P>0.05). Compared with group C, the Longa score and cerebral infarct volume were significantly increased, the percentage of novel object exploration and discrimination index were decreased, the expression of p-PI3K, p-Akt, PSD-95 and SYN in hippocampal tissues was down-regulated, and the dendritic length and dendritic spine density of hippocampal neurons were decreased in IR, P and LY groups ( P<0.05). Compared with group IR, Longa score and cerebral infarct volume were significantly decreased, the percentage of novel object exploration and discrimination index were increased, the expression of p-PI3K, p-Akt, PSD-95 and SYN in hippocampal tissues was up-regulated, and the dendritic length and dendritic spine density of hippocampal neurons were increased in group P ( P<0.05), and no significant change was found in the parameters mentioned above in group LY ( P>0.05). Compared with group P, Longa score and cerebral infarct volume were significantly increased, the percentage of novel object exploration and discrimination index were decreased, the expression of p-PI3K, p-Akt, PSD-95 and SYN in hippocampal tissues was down-regulated, and the dendritic length and dendritic spine density of hippocampal neurons were decreased in group LY ( P<0.05). Conclusions:Pre-injection of young rat plasma can attenuate cognitive dysfunction after cerebral I/R in aged rats, and the mechanism is related to activation of hippocampal PI3K/Akt signaling pathway and improvement in synaptic plasticity.

Dry eye is becoming more common worldwide.Its pathophysiology is complicated, and its condition is chronic.Treatment options of dry eye are ineffective.As a multifactorial ocular surface disease, tear film instability, tear hyperosmolarity, ocular surface inflammation, and neurosensory abnormalities resulted from various causes are main natural pathological processes of dry eye.This multifactorial process of the disease leads to poor efficacy of single anti-inflammatory therapy.Oxidative stress is closely related to the occurrence of dry eye.During the decrease of tear film stability, reactive oxygen species produced by oxidative stress system damage the myelin sheath of ocular nerve and the lipid layer of tear film, inducing or aggravating the ocular inflammatory response.Targeting the main causes of dry eye's pathogenesis, stopping the vicious cycle of inflammatory responses in each link, and relieving patients' conditions are the main goals of antioxidant therapy.The development of anti-inflammatory and antioxidant medications is currently the main focus of international research on novel anti-dry eye medications.Some progresses have been made in the area of targeting oxidative stress biomarkers, mitochondrial targeting medications, mucin secretion, antioxidant enzymes like glycoprotein selenium and lactoferritin, as well as multifunctional nanoagents, and the antioxidant eye drops using nanomaterials have more advantages.Antioxidant treatment may be one of the potential future avenues of dry eye clinical research.Ophthalmologists and researchers should be fully aware of, pay close attention to and actively participate in investigations that are relevant to dry eye antioxidant therapy and the development of new medications.

Objective:To design a replaceable corneal scaler and explore its effect on improving the positive detection rate of corneal bacteria and the cure rate of patients with infectious keratitis.Methods:Totally 100 patients with infectious keratitis treated in the Eye&Ent Hospital of Fudan University in Shanghai from June 2020 to October 2021 were conveniently selected as the application object, 50 patients from June 2020 to January 2021 were selected as the control group, and 50 patients from February 2021 to October 2021 were selected as the experimental group. The control group used the traditional corneal scalpel for corneal scraping, and the experimental group used the replaceable corneal scalpel for corneal scraping. The positive detection rate of bacteria, the cure rate of patients as of the date of data collection, the comfort status of patients and the operation difficulty score of medical staff were compared between the two groups.Results:The 28 cases (56%) were positive in the experimental group, and 30 cases (60%) were cured as of the date of data collection; 16 cases (32%) were positive in the control group and 18 cases (36%) were cured as of the date of data collection. The difference between the two groups was statistically significant ( χ2=-2.47, -2.20, all P<0.05). The score of comfort in the experimental group was (83.92 ± 6.40) and that in the control group was (54.04 ± 10.69). The difference between the two groups was statistically significant ( t=17.14, P<0.01). The operation difficulty score of medical staff in the experimental group was (1.46 ± 0.54) and that of medical staff in the control group was (3.24 ± 0.72). The difference between the two groups was statistically significant ( t=-13.50, P<0.01). Conclusions:The use of replaceable corneal scalpel can not only improve the positive detection rate of patients, improve the treatment effect of patients, improve the comfort and satisfaction of patients, but also improve the work efficiency of medical staff and reduce the operational risk of medical staff, so as to improve the real professional value of medical staff.
