The occurrence and development of a variety of retinal diseases are related to inflammatory responses,and various inflammatory cells play an important role in retinal damage,which can lead to vision impairment,vision loss,and blindness.Microglia are resident immune cells in the retina,distributed in the inner layer of the retina.They mainly maintain the normal homeostasis of the retina,regulate the apoptosis of neurons,and play an immune surveillance role in the retina.Under inflammatory stimulation,microglia in the retina are activated,secrete a variety of inflammatory factors,engulf neurons and photoreceptors,and destroy the blood-retinal barrier,aggravating retinal damage.This article reviews the physiological function of microglia and the changes in microglia under the inflammatory effects of various retinal diseases.It also discusses how to inhibit microglia from damaging the retina and promote microglia to control retinal inflammation,thereby providing a basis for the clinical treatment of various retinal diseases.

Objective:To explore the effect of health status on the elder care choice,providing empirical evidence to optimize care provision and deepen the understanding of family risk-coping mechanisms.Method:Multinomial Logit model was used to examine the effects of health stock and health changes on the elder care choice,followed by an income heterogeneity analysis.Results:The impact of health status on the choice of elder care arrangements exhibited clear pathway differentiation and group heterogeneity.In the long-term effect,poor baseline cognitive ability was a key factor driving the elderly to turn to their children for elderly care,with each one-point decrease in the MMSE score increasing this probability by an average of 0.5 percentage points.In the short-term effect,an acute deterioration in either physical function(ΔADL)or cognitive ability(ΔMMSE)significantly increased the likelihood of transitioning to living with children,with the probabilities increasing by an average of 1.7 and 0.3 percentage points,respectively.In contrast,transitioning to institutional care—in both the long and short term—was driven solely by the deterioration of physical function,increasing the probability by 0.4 and 0.3 percentage points,respectively.The heterogeneity analysis further revealed that these clear decision pathways hold primarily for the high-income group,while the elder care choice of the low-income group was less sensitive to health indicators.Conclusion:The elder care choice is not solely determined by health risks but is a social process where health status and family economic resources are closely intertwined,ultimately manifesting as a divergence between the"strategic choices"of high-income groups and the"constrained reactions"of low-income groups.

Objective:To investigate the differences of the glymphatic system (GS) function between patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) and healthy controls and between different seizure types by using diffusion tensor imaging along perivascular space (DTI-ALPS), and to analyze the correlation between GS function and the course of disease, as well as the efficacy of predicting the surgical outcome.Methods:This study was a cross-sectional study. A total of 171 patients with mTLE-HS (mTLE-HS group) and 75 healthy volunteers (HC group) were retrospectively enrolled from July 2009 to July 2021 at Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University. The general information of all subjects, such as seizure type (partial seizure, secondary generalized seizure), surgical outcome, etc., was analyzed. The 3D magnetization prepared rapid gradient echo T 1WI and DTI sequence images were collected. The VBM analysis method was used to segment cerebrospinal fluid and calculate the volume. The ALPS index of the bilateral brain was calculated using the Atlas-based DTI-ALPS method. Independent sample t-test or paired t test were used to compare the ALPS index between the mTLE-HS group and HC group, and between patients with different seizure types. Pearson correlation analysis was used to analyze the correlation between bilateral ALPS index and disease duration in mTLE-HS group. The predictive value of the ALPS index for surgical outcomes was evaluated by receiver operating characteristics curve and area under the curve. Results:Among the 171 mTLE-HS patients, 98 patients were mTLE with left-side HS (mTLE-LHS) and 73 patients were mTLE with right-side HS (mTLE-RHS); 37 patients underwent surgical treatment, including 27 with good prognosis and 10 with poor prognosis. Compared with the HC group, the left-side ALPS index of mTLE-LHS and mTLE-RHS were both decreased ( P<0.05). The right-side ALPS index in mTLE-RHS was lower than that in the HC group ( P<0.001). There was no significant difference in the right-side ALPS index between mTLE-LHS and HC group ( P=0.080). The ALPS index on the affected side of patients with secondary generalized seizures was significantly lower than that of patients with only partial seizures (all P<0.05), but the difference in ALPS index on the healthy side was not statistically significant( P>0.05). The left-side and right-side ALPS index in mTLE-LHS were negatively correlated with disease duration ( r=-0.272, P=0.007; r=-0.307, P=0.002), but no significant correlation was found between the left-side or right-side ALPS index in mTLE-RHS (all P>0.05). The DTI-ALPS index on the affected side in mTLE-HS patients exhibited good diagnostic accuracy for surgical outcome classification, with an area under the curve of 0.778. Conclusions:The patients with mTLE-HS exhibit dysfunction of the GS, and the degree of impairment is related to the type of seizure and the course of epilepsy. The ALPS index, which characterizes the function of GS, demonstrates good diagnostic accuracy for classifying surgical outcomes.

Objective To compare the clinical efficacy and safety of early endovascular treatment(EVT)for the stroke patients caused by large vessel occlusion(LVO)due to intracranial atherosclerosis(ICAS)or due to cardioembolism(CE).Methods The clinical data of 488 patients with acute anterior circulation LVO stroke,who received early endovascular treatment at the Yijishan Hospital of Wannan Medical College of China from October 2015 to December 2023,were retrospectively analyzed.According to the cause of disease,the patients were divided into ICAS group(n=108)and CE group(n=380).The clinical data,mainly including the proportion of patients having a good prognosis at 90 days after operation(modified Rankin Scale score ≤2 points),the incidence of symptomatic intracranial cerebral hemorrhage(sICH),and the mortality of patients at 90 days after operation.Multivariate logistic regression analysis was used to analyze the factors influencing patient's prognosis.Results Of the 488 patients,29(5.9％)developed postoperative sICH,242(49.6％)achieved a good prognosis at 90 days after the operation,and 91(18.6％)died.The above outcomes in the ICAS group were one,66,and 11 patients respectively,which in the CE group were 28,176,and 80 respectively,and the differences between the two groups were statistically significant(all P＜0.05).Multivariate logistic regression analysis indicated that good prognosis at 90 days after the operation(OR=0.962,95％CI:0.404-2.288,P=0.930)and the postoperative 90-day mortality(OR=1.379,95％CI:0.436-4.362,P=0.584)were not the factors influencing prognosis,while the postoperative sICH(OR=19.132,95％CI:1.332-274.791,P=0.030)was the factor influencing prognosis.Conclusion In CE group,the incidence of sICH and the postoperative 90-day mortality are higher,while in ICAS group,the postoperative 90-day good prognosis rate is higher.The postoperative sICH is the factor influencing prognosis.

Objective:To investigate the short-term clinical efficacy of two fixation methods, mini-titanium plate fixation and suture suspension, in cervical posterior unilateral laminoplasty, and to explore the relationship between changes in the cervical sagittal sequence and therapeutic outcomes.Methods:A retrospective analysis was conducted on 55 patients who underwent cervical posterior unilateral laminoplasty with mini-titanium plate fixation and 50 patients with suture suspension at the First People's Hospital of Lianyungang from September 2020 to January 2023. All patients were followed up for 12 months, and the axial symptoms was recorded. The main clinical efficacy evaluations included before surgery and 12 months after surgery visual analog score (VAS) for neck pain, Japanese Orthopaedic Association score (JOA) and neck disability index (NDI). Four parameters were recorded before surgery and 12 months after surgery to assess the sagittal sequence: C 2-7 sagittal vertical axis (C 2-7SVA), T 1 slope angle (T 1s), C 2-7Cobb angle and cervical range of motion. Results:The mini-titanium plate fixation group had 5 cases of axial symptoms, while the traditional suture suspension group had 16 cases; the postoperative VAS, JOA and C 2-7Cobb angle in the mini-titanium plate fixation group were all less than those in the suture suspension group, with statistically significant differences ( P<0.05). Specifically, the postoperative VAS in the mini-titanium plate fixation group was (1.93 ± 1.42) points, and (2.67 ± 2.15) points in the suture suspension group ( P = 0.049); the JOA was (10.39 ± 2.20) points in the mini-titanium plate fixation group and (9.62 ± 1.52) points in the suture suspension group ( P = 0.012); the C 2-7Cobb angle was (21.087 ± 3.564)° in the mini-titanium plate fixation group and (23.092 ± 1.265)° in the suture suspension group ( P = 0.003). There was no statistical difference in operation time and blood loss between two groups ( P>0.05). The postoperative C 2-7SVA, T 1s and range of motion in the traditional suture suspension group were less than those in the mini-titanium plate fixation group, with statistically significant differences ( P<0.05). Specifically, the postoperative C 2-7SVA was (25.700 ± 3.035) mm in the mini-titanium plate fixation group and (23.946 ± 3.079) mm in the suture suspension group ( P = 0.004); the postoperative T 1s was (28.770 ± 2.361)° in the mini-titanium plate fixation group and (26.746 ± 3.198)° in the suture suspension group ( P = 0.004); the postoperative range of motion was (32.651 ± 4.995)° in the mini-titanium plate fixation group and (28.672 ± 5.874)° in the suture suspension group ( P = 0.003). Conclusions:Cervical posterior unilateral laminoplasty with mini-titanium plate fixation can effectively improve VAS, JOA, and restore neurological function, maintaining the cervical spine's sagittal balance, stability, and maximum range of motion.

There was no significant difference in the right-side ALPS index between mTLE-LHS and HC group ( P=0.080). The ALPS index on the affected side of patients with secondary generalized seizures was significantly lower than that of patients with only partial seizures (all P<0.05), but the difference in ALPS index on the healthy side was not statistically significant( P>0.05). The left-side and right-side ALPS index in mTLE-LHS were negatively correlated with disease duration ( r=-0.272, P=0.007; r=-0.307, P=0.002), but no significant correlation was found between the left-side or right-side ALPS index in mTLE-RHS (all P>0.05). The DTI-ALPS index on the affected side in mTLE-HS patients exhibited good diagnostic accuracy for surgical outcome classification, with an area under the curve of 0.778. Conclusions:The patients with mTLE-HS exhibit dysfunction of the GS, and the degree of impairment is related to the type of seizure and the course of epilepsy. The ALPS index, which characterizes the function of GS, demonstrates good diagnostic accuracy for classifying surgical outcomes.

ObjectiveTo evaluate some properties of scutellarin-phospholipid complex nanoemulsion（SCU-PC-NE）， such as release， cell uptake and tissue distribution， and to investigate its effect on ameliorating lipopolysaccharide（LPS）-induced vascular endothelial injury. MethodSCU-PC-NE was prepared by weighting SCU-PC， ethyl oleate， Kolliphor HS15， 1，2-propylene glycol（50， 400， 514.3， 85.7 mg）， respectively. And the appearance of SCU-PC-NE was observed by transmission electron microscope， the average paticle size and Zeta potential were measured by nanopotential particle size analyzer. The cumulative release of SCU-PC-NE in vitro was measured by dynamic dialysis， thiazolyl blue（MTT） colorimetric assay was used to investigate the effect of SCU-PC-NE on the viability of human umbilical vein endothelial cells（HUVECs）， the inverted fluorescence microscope and flow cytometry were used to investigate cell uptake of HUVECs by SCU-PC-NE in vitro using coumarin 6 as a fluorescent probe， the tissue distribution of DiR/SCU-PC-NE labeled by near infrared fluorescent dyes was obeserved by small animal in vivo imaging system. The inflammation injury model was established by co-incubation with LPS（1 mg·L^-1） and HUVECs， the effect of SCU-PC-NE on the levels of interleukin（IL）-1β and IL-6 were determined by enzyme-linked immunosorbent assay（ELISA）， 18 Kunming male mice were randomly divided into blank group， model group， blank preparation group（equivalent to high dose group）， SCU group and SCU-PC-NE low and high dose groups（5， 10 mg·kg^-1）， 3 mice in each group， and the drug administration groups were administered once in the tail vein at the corresponding dose every 48 h， equal volume of normal saline was given to the blank group and the model group， and the drug was administered for 4 consecutive times. Except for the blank group， the endothelial inflammatory injury was induced by intraperitoneal injection of LPS（10 mg·kg^-1） at 12 h before the last administration in each group. Hematoxylin-eosin（HE） staining was used to investigate the effect of SCU-PC-NE on the histopathological changes in the thoracic aorta of mice. ResultThe appearance of SCU-PC-NE displayed pale yellow milky light， mostly spherical with rounded appearance and relatively uniform particle size distribution， with the average particle size of 35.31 nm， Zeta potential of 7.23 mV， and the encapsulation efficiency of 75.24%. The cumulative release in vitro showed that SCU-PC-NE exhibited sustained release properties compared with SCU. The cell viability of SCU-PC-NE was >90% at a concentration range of 1.05-8.4 mg·L^-1. The results of cellular uptake experiments showed that the cellular uptake ability of SCU-PC-NE was significantly enhanced when compared with the SCU group（P<0.01）. Compared with normal mice， the results of tissue distribution showed that the fluorescence intensity of DiR/SCU-PC-NE was significantly enhanced in the spleen， kidney， brain and thoracic aorta of mice at different time points after intraperitoneal injection of LPS（P<0.05， P<0.01）， especially in thoracic aorta. ELISA results showed that the levels of IL-1β and IL-6 in the model group were significantly increased when compared with the blank group（P<0.05， P<0.01）， and compare with the model group， all administration groups significantly down-regulated IL-1β level， with the strongest effect in the SCU-PC-NE high-dose group（P<0.01）， and all administration groups significantly down-regulated IL-6 level， with the strongest effect in the SCU-PC-NE low-dose group（P<0.05）. Compare with the blank group， the results of HE staining showed that the endothelial cells were damaged， the elastic fibers were broken and arranged loosely in the model group， although similar vascular injury could be observed in the blank preparation group， SCU group and SCU-PC-NE low-dose group， the vascular endothelial damage was significantly reduced in the high-dose group of SCU-PC-NE， which had a better effect than that in the SCU group. ConclusionSCU-PC-NE can promote the uptake of drugs by endothelial cells and effectively enriched in the site of vascular endothelial injury caused by LPS， suggesting that it has a protective effect on vascular endothelial injury and is a good carrier of SCU.
