Diabetic macular edema(DME)and age-related macular degeneration(ARMD)are the leading causes of visual impairment and blindness worldwide, and their common pathological features are increased vascular permeability and abnormal neovascularization, in which cytokines such as vascular endothelial growth factor(VEGF)and angiopoietin-2(Ang-2)play an important role. Intravitreal injection of anti-VEGF agents significantly changed the clinical management of DME and ARMD, but limitations such as the non-responsive cases, the treatment burden and risks caused by frequent injections need to be overcome. Faricimab, a novel bispecific monoclonal antibody that simultaneously targets VEGF-A and Ang-2, can effectively reduce vascular permeability, decrease the number of neovascularization and alleviate retinal edema. Registered clinical studies have shown that Faricimab is effective in improving vision and reducing retinal edema, which is non-inferior to Aflibercept and Ranibizumab, maintains a long dosing interval, and has a high safety profile. This article reviews the latest advances in the treatment of DME and ARMD with Faricimab.

Autophagy is an important homeostatic cellular recycling mechanism responsible for degrading injured or dysfunctional cellular organelles and proteins in all living cells. Aging is a universal phenomenon characterized by progressive deterioration of cells and organs due to accumulation of macromolecular and organelle damage. Growing evidences indicate that the rate of autophagosome formation and maturation and the efficiency of autophagosome/lysosome fusion decline with age. Dysfunctional autophagy has also been observed in age-related diseases. Autophagy disruption resulted accumulation of mutated or misfolded proteins is the essential feature of neurodegenerative disorders. However, in cancers, fibroproliferative diseases or cardiovascular diseases, autophagy can play either a protective or destructive role in different types of disease, and even in different stages of the same disease. The review will discuss the cellular and molecular mechanisms of autophagy and its important role in the pathogenesis of aging and age-related diseases, and the ongoing drug discovery strategies for therapeutic intervention.

Objective To evaluate the impact of pancreatic duct hanging and continuous suturing maneuver in end-to-side pancreaticojejunostomy on the incidence of pancreatic fistula after pancreaticoduodenectomy (PD),and to study the feasibility,safety and efficacy.Method 165 patients who underwent pancreaticoduodenectomy were randomly selected and the incidences of pancreatic fistula for the different types of pancreaticojejunostomy were analyzed.Results The overall rate of pancreatic fistula was 13.9％ (23/165).The incidences of pancreatic fistula after pancreatic duct hanging and continuous suturing maneuver in end-to-side anastomosis (3.1％,2/65,group C) was significantly lower than the traditional intussusception anastomosis (23.1％,12/52,group A,P＜0.05) and the mucosa mucosa anastomosis (18.8％,9/48,group B).There was no significant difference between the traditional intussusception anastomosis and the mucosa mucosa anastomosis (P＞0.05).In group C,the average operative time,intraoperative blood loss,and postoperative drainage was obviously superior to the A and B group (P＜0.05).There was no significant difference between the A and B group (P＞0.05).The other complications showed no significant differences among the three groups (P＞0.05).Conclusion Pancreatic-duct hanging and continuous suturing maneuver in end-to-side anastomosis significantly reduced the rate of pancreatic fistula after pancreaticoduedenectomy.It was feasible,safe,convenient to use and should be popularized.

Objective To explore the changes of cytokine levels and their roles in morbidity of autoimmune thyroid disease(AITD) in children.Methods The serum concentrations of interleukin-4(IL-4),interleukin-6(IL-6),tumor necrosis factor-?(TNF-?),interferon-? (IFN-?) were determined with enzyme linked immunosorbent assay (ELISA) among 30 patients with Graves′ disease (GD) and 20 patients with Hashimotos thyroiditis(HT) and 30 children without AITD subjects.Results The serum levels of IL-4 and IL-6 in patients with GD were higher than those of subjects (Pa

Objective To analyze quantitatively the safety and efficacy of statin therapy in acute phrase for acute ischemic stroke with the method of meta-analysis.Methods We performed a systematic literature search including the Cochrane Library,MEDLINE and EMBASE for published trials about statin therapy and the outcomes of acute ischemic stroke.Then we performed a meta-analysis with included studies to investigate the association between statin therapy and clinical outcome and mortality.All of the data were pooled and meta-analyzed by Cochrane Collaboration RevMan 5.3 meta-analysis software.Statistical heterogeneity between studies was evaluated by the chi-square and I-square tests.Forest plots were used to summarize study data and Egger tests were used to assess publication bias.Results A total of 27 studies including 52 034 patients,comprising 19 212 statin users and 32 822 non-statin users met the inclusion criteria,4 studies were randomized controlled trials (RCTs),and 23 were observational trials (OTs).Both pre-or post-stroke statin use was associated with reduced mortality.Statin use is associated with favorable functional outcome at hospital discharge and on the ninetieth day regardless of initiation time for pre-stroke group and post-stroke group.The results from observational trials were consistent with randomized controlled trials.There was no evidence of publication bias for all comparisons by Egger tests.Conclusions Statin therapy before or after AIS is safe and effective.

Objective To evaluate a modified liver hanging maneuver(retrohepatic tunnel of the IVC) in patients undergoing hemihepatectomy.Methods Twenty-four patients undergoing hemihepatectomy were divided into two groups:modified liver hanging maneuver group(n=12)and Pringle's maneuver group(n=12).The amount of intraoperative bleeding,operation time,postoperative liver function,liver function recovery and complications were compared between the two groups.Reset All operation were performed successfully and there were no difference in the time of operation etween the two groups.There was a difierence in the amount of mean intraoperative blood loss between the two groups.It was(160±40)ml in liver hanging group and(560±120)ml in Pringle's group(P＜0.01).Liver function recovery measured on postoperative day 3 and day 7 was better in liver hanging groupthan that in Pringle's group(P＜0.01).The volume of postoperative peritoneal serous fluid dranage was significantly less in liver hanging group(P＜0.01).Conclusion The modified liver hanging maneuver is useful for hemihepatectomy.

Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

Objective To investigate the correlation between cerebral artery stenosis (MCAS) and mild cognitive impairment (MCI).Methods Continuous selected 636 cases of 50-80 years old inpatients or outpatients who examined by transcranial color Doppler ultrasound (TCD) in April 2012 to April 2013 in our hospital.Keep the mini-mental state examination (MMSE) and clinical dementia rating (CDR) as the evaluation of cognitive function.Results Detected 124 cases of MCAS patients (MCAS group) and 512 cases of non-MCAS patients (non-MCAS group).Forty-four cases MCI were detected in MCAS group with the prevalence rate was 35.5％(44/124),and 114 cases of patients with MCI were detected in non-MCAS group with the prevalence rate was 22.3％ (114/512),the difference was statistically significant (P ＜ 0.05).Single factor analysis showed that there were no significant difference between two groups in waist circumference,hypertension,coronary heart disease,hyperlipidemia,smoking,diastolic blood pressure and total cholesterol,uric acid,fasting glucose,C-reactive protein (P ＞ 0.05); There were significantly different between two groups in age,gender,education level,MCAS,history of diabetes,systolic blood pressure and triglyceride,low density lipoprotein-cholesterol,high-density lipoprotein-cholesterol(P ＜ 0.05).Multiple factors analysis showed that the MCAS (OR =1.899,95％ CI 1.224-2.946),history of diabetes (OR =1.764,95％ CI 1.191-2.612),systolic blood pressure(OR =1.012,95％ CI 1.003-1.022),gender (OR =0.558,95％ CI 0.380-0.821),and age (OR =1.029,95％ CI 1.010-1.049) was the independent risk factor for MCI.Conclusion The MCAS related with MCI occurrence and development.
