The complex anatomical structure and physiological barriers of the eye present substantial challenges for local drug delivery, leading to suboptimal ocular drug bioavailability, which typically remains below 5% in conventional ophthalmic formulations. Frequent or high-dose administration not only increases the treatment burden but also heightens the risk of both local and systemic adverse effects. Liposomes, as an advanced drug delivery system, enhance ocular bioavailability through their biocompatibility and targeted delivery properties. Recent innovations in surface modification and functionalization have further enhanced their ability to overcome ocular barriers and facilitate controlled drug release. Liposome-based formulations have demonstrated significant therapeutic potential for diseases such as glaucoma and dry eye syndrome. Drawing on the research advancements over the past 5 a, this article systematically reviews the innovative design strategies and applications of liposomes in ocular drug delivery, with the aim of providing theoretical basis and technical reference for the development of new ophthalmic drugs.

Objective:To assess the efficacy and safety of common medication treatments on Kaposiform hemangioendothelioma (KHE) and tufted angioma (TA).Methods:PubMed, Embase, Web of Science, CNKI and Wanfang database were searched to find out the observational studies on medication treatment of KHE and TA. R-3.6.2 was used for calculate the pooled response rate and pooled adverse events rate. Meta analyses were performed according to KHE and TA with and without Kasabach-Merritt phenomenon (KMP) respectively. SPSS 22.0 was used to compare the pooled rates among each therapy.Results:A total of 30 studies regarding the medication treatment of KHE and TA were identified in this meta-analysis. Analyzed medicines included glucocorticoid, vincristine, sirolimus, propranolol, combination therapy of vincristine and glucocorticoid. The pooled results indicated that when referring therapy on KHE and TA with KMP, the pooled response rate of combination therapy (98.34%) and sirolimus (96.43%) was higher than that of other therapies, and the difference was statistically significant. The pooled adverse events rate of sirolimus (5.53%) was relatively higher than other modalities, with no statistically significance. As for therapy on KHE and TA without KMP, sirolimus (94.23%) had higher pooled response rate than glucocorticoid (31.25%), vincristine (46.15%) and propranolol (22.86%), with statistically significant differences. The pooled adverse events rate of sirolimus was 23.81%.Conclusions:Our findings indicate that for KHE and TA with KMP, combination therapy (sirolimus + glucocorticoid) and vincristine have the best efficacy, while the adverse events rate of sirolimus is relatively high. For KHE and TA without KMP, sirolimus has the highest response rate, but there is also a risk of serious adverse events. Glucocorticoid and vincristine have comparable response rate, which both inferior to sirolimus.

Objective: To compare the differences and similarities in emotional and behavioral problems among children with developmental dyslexia (DD), attention deficit hyperactivity disorder (ADHD) or both, aiming to provide basis for targeted intervention. Methods: Strengths and Difficulties Questionnaire (SDQ) was used to investigate emotional and behavioral problems among four groups of children (DD=32, ADHD=32, DD+ADHD=14, TD=32). Hierarchical regression analysis was recruited to investigate the associations of emotional and behavioral problems with spelling impairment or ADHD symptoms. Results: Except for peer problems, emotional and behavioral problems varied in the four groups [prosocial DD: (641±2.75), ADHD: (5.53±2.49), combined: (7.07±2.37), control: (7.72±2.19), F=4.42, P<0.05; emotional problems DD: (1.81±1.94), ADHD: (3.66±1.66), combined: (3.21±2.33), control: (2.03±1.99), F=6.36， P<0.05; conduct problems DD: (2.31±1.23), ADHD: (3.66±1.77), combined: (2.64±1.98), control: (1.97±1.31), F=7.24, P<0.05; difficulties score DD: (6.94±2.96), ADHD: (10.28±3.90), combined: (9.07±3.17), control: (6.06±3.94), F=8.82, P<0.05 ], most serious in ADHD group. In addition, children in DD group scored higher than those in normal group in terms of prosocial behavior. Children in the combined group showed higher total scores of peer problems and difficult score than those in the normal group. Emotional symptoms were more serious among children in combined group than those in the DD group. Compared with the combined group, behavioral problems in ADHD group were more common. Hierarchical regression analysis indicated that occurrence of emotional and behavioral problems in combined group was mostly mediated by hyperactivity symptoms. Conclusion Compared with DD group, children with ADHD combined or not combined with DD show more emotional and behavioral problems. Emotional and behavioral problems are notably observed among those with hyperactivity symptoms than DD.

Objective To observe the level changes and clinical diagnostic value of follicular statin -1 (FSTL1)in the serum of patients with different types of acute coronary syndrome(ACS).Methods Collected the clinical diagnosis of acute coronary syndrome patients 98 cases,which contained ST segment elevation my-ocardial infarction(STEMI)in 34 cases,non ST elevation myocardial infarction(NSTEMI)in 28 cases,unsta-ble angina pectoris(UA)in 36 cases,while the examination resuLts of healthy people as a control group of 20 cases.The Venous blood was collected and the FSTL1 levels of the 4 groups were detected by ELISA.Results The levels of Serum FSTL1 in ACS group was significantly higher than that in normal control group(P<0.05).Serum FSTL1 of the ACS group were significant correlated with Gensini score,cTNT,hs-CRP(related coefficient:0.210,0.236,0.219 separately).The AUC of FSTL1 was 0.910(95% CI:0.832 -0.988),which was lower than cTNT.The best cut-off value of FSTL1 as a biomarker was 5.65 μg/L(specificity:84.2% and sensitivity:77.5%).Moreover the combination of FSTL1,HDL and cTNT exhibited significantly higher AUC=0.945(95% CI:0.909 -0.981)than did other biomarkers alone or pair combinations.Conclusion In pa-tients with acute coronary syndrome,serum FSTL1 levels has a positive correlation with the degree of coro-nary stenosis and inflammation reaction,and has certain value in the diagnosis of acute coronary syndrome.

Objective To explore the value of serum ischemia modified albumin (IMA) level in assessment of disease severity for patients with chronic obstructive pulmonary disease (COPD).Methods A total of 81 cases of patients with COPD treated in our hospital from September 2015 to March 2016 were selected (COPD group),including 51 cases of patients with acute exacerbation of COPD and 30 cases of patients with stable of COPD.Meanwhile,30 volunteers without COPD were collected as control group.Serum levels of IMA were detected and compared among different groups.Correlations between serum level of IMA and serum level of myoglobin (MYO),troponin T (TNT) and C reactive protein (CRP),and white blood cell (WBC) count were analyzed respectively.A receiver operating characteristic (ROC) curve was also plotted to investigate the diagnostic value of serum IMA level for diagnosing COPD.Results Serum level of IMA in the COPD group was higher than that in the control group [84.1 (79.1,88.5) U/L vs.73.1 (70.2,75.1)U/L],serum level of IMA in patients with acute exacerbation of COPD was higher than that of patients with stable of COPD [85.5 (82.3,89.4)U/L vs.78.1 (75.9,83.0)U/L],serum levels of IMA in patients with acute exacerbation and stable of COPD both were higher than that in the control group,there were statistically significant differences (P＜0.05).The serum level of IMA was positively related with serum level of MYO in patients with COPD (r=0.554,P =0.00).ROC curve indicated when the cutoff value was set as 76.55 U/L,the sensitivity and specificity of serum level of IMA for diagnosing COPD was 88.5％ and 80.0％ respectively,and area under the ROC curve was 0.88.Conclusion Serum level of IMA could be a valuable indicator for clinically assessing disease severity of patients with COPD,which deserves further study through expanding samples size.

Objective: To provide an important tool for the study of diagnose and treatment of prostate cancer (PCa) osseous metastasis and change of bone stress force on prostate cancer (PCa) osseous metastasis and a platform, which is more congruous to clinical process, for prevention and cure of neoplastic bone metastases, and to carry out the construction and improvement of animal models of PCa with different positional osseous metastasis in vivo.Methods: Different gradient concentrations of RM-1 cells were inoculated into the cavity of left femoral bone or lumbar vertebra of mice (C57BL/6) respectively.The change of mouse activity, tumor formation, tumor size and survival time were observed respectively.And the femur tissue and spinal tissue were obtained from the mice after death.The gray value of iconography were measured by imageological examination of femur tissue, and the final histopathological examination were taken to determine the tumor type in both femur and spinal tissue.Results: The tumor growth could be touched at the puncture site in all the mice after inoculated for 7 days.There were no obvious differences in the time of tumorigenesis, the rate of tumor growth and tumor size among the mice in the same group (P>0.05).As the result, the construction femoral bone and lumbar vertebra metastatic models of PCa had been confirmed by iconography and pathology detection.At the same time, the survival time of the mice inoculated with low concentrations of PCa cells was obviously longer than that of high concentrations of PCa cells (at least 2 weeks longer).Conclusion: The animal models with different positional osseous metastasis (limbs and axial skeleton) of PCa using the same PCa cells (RM-1) had been first constructed successfully in our study.At the same time, a high success rate of construction of PCa animal model with bone metastasis was obtained by femoral bone marrow cavity injection of PCa cells.The rate of tumor growth was rapid, animal survival time was appropriate, and the PCa animal model with bone metastasis can be stably reproduced by our method.These animal models can be used to explore the pathogenesis of different positional PCa bone metastasis and provide a new platform, which were more congruous to clinical process, for prevention and cure of neoplastic bone metastases.

Objective To evaluate the diagnostic value of combination detection of alpha-fetoprotein (AFP),Golgi protein 73 (GP73) and a-L-fucosidase (AFU) for early hepatocellular carcinoma (HCC).Methods A total of 222 patients with liver diseases in this hospital from March 2016 to March 2017 were collected and divided into the early stage HCC group (74 cases),late stage HCC group (27 cases),liver cirrhosis group (74 cases) and chronic hepatitis B group (47 cases),and contemporaneous 49 individuals undergoing physical examination were selected as the healthy control group.The levels of serum GP73,AFP and AFU were detected in each group.The ROC curve was drawn.The diagnostic values of single detection and combined detection of 3 indicators for diagnosing early HCC were evaluated.Results The serum GP73,AFP and AFU levels in the early stage HCC group were significantly higher than those in the liver cirrhosis group,chronic hepatitis B group and healthy control group (P＜0.05).In the HCC screening,the area under the curve (AUC) of AFP ROC curve for singly diagnosing HCC was 0.910(95％CI:0.864-0.936),AUC of GP73 and AFP combined diagnosis was maximal [0.925 (95％ CI:0.889-0.950)] and the sensitivity was the highest (95.0％).In the differentiation diagnosis between early HCC and liver cirrhosis,AUC of GP73 for single diagnosis was maximal [0.842(95％CI:0.746-0.879)] and the specificity was the highest (86.5％);AUC of GP73 and AFU combined diagnosis was maximal[0.901(95％CI:0.788-0.907)].Conclusion GP73 and AFP for combined detection of HCC can increase the diagnostic efficiency of HCC screening.GP73 and AFU combined diagnosis can increase the diagnosis efficiency of early HCC,which has an important significance for the differentiation diagnosis between early HCC and liver cirrhosis.

Objective To evaluate the diagnostic performances of seven estimation formulas for glomerular filtration rate (GFR) in pre-operative patients with renal cell carcinoma.Methods A total of 386 pre-operative patients with renal cell carcinoma in the first affiliated hospital of Chongqing medical university from January 2012 to October 2014 were selected.All the patients' GFRs were measured by the renal dynamic imagingwith 99mTc-DTPA as reference (rGFR) and the seven GFR estimation equations (eGFR) were compared with the rGFR respectively.Their correlations and consistencies were observed with spearman correlation analysis and Bland and Altman analysis.The diagnostic sensitivity,specificity and likelihood ratios were calculated and the eGFR accuracies were assessed with receiver operator curve (ROC) analysis.Results The correlations between the rGFR and eGFRs were significantly (P＜0.001).In addition,CKD-EPI-Asian Crea and Ruijin formula were more accurate than others in different stages with larger ROC area in diagnosing renal cell carcinoma.Conclusion There were significant correlations between the eGFRs and rGFR,but some deviations existed.CKD-EPI-Asian Crea and Ruijin formula were more suitable for assessment of eGFR of pre-operative patients with renal cell carcinoma.However,both of these equations had a few limitations.
