Allergic conjunctivitis is a common ocular inflammatory disease, with intense itching being the most typical and distressing symptom for patients. In recent years, with the in-depth study of the interaction between the nervous and immune systems, significant progress has been made in understanding the mechanism of itching in allergic conjunctivitis. This review elaborates on the neurobiological basis of itching in allergic conjunctivitis, with a focus on the complex dialogue between immune cells and sensory neurons, particularly the core role of the IL-33-ST2-CGRP signaling axis in mediating itching. Additionally, this article introduces new findings in genetic susceptibility research, including the identification of susceptibility genes for allergic conjunctivitis through transcriptome-wide association studies. The sensory nervous system not only transmits itch signals but also actively participates in the formation of antigen channels related to conjunctival goblet cells, thereby regulating the local uptake of allergens and the initiation of the immune response. Moreover, targeted novel therapeutic strategies offer hope for patients with refractory allergic conjunctivitis. Exploring the molecular and cellular mechanisms of itching in allergic conjunctivitis will provide a theoretical basis for the development of more effective treatment methods.

Objective To investigate the correlation between vitamin A,E,D and folic acid levels and concomitant preeclampsia(PE)in patients with gestational diabetes mellitus(GDM).Methods A total of 108 patients with GDM complicated with PE were used as the PE group,and another 108 GDM patients without PE were used as the GDM group.A total of 108 normal pregnant women with normal pregnancy test were used as the normal control group.The general information and vitamin A,E,D and folic acid levels were compared between the three groups.According to the severity of the disease,the PE group was subdivided into the mild-moderate PE group(62 cases)and the severe PE group(46 cases),and vitamin A,E,D and folic acid levels were compared between these two groups.Results Systolic blood pressure(SBP),diastolic blood pressure(DBP),fasting blood glucose(FBG),fasting insulin(FINS)were increased in turn in the normal control group,the GDM group and the PE groups(P＜0.05),and vitamins A,E,D and folic acid levels were decreased in turn(P＜0.05).Triglyceride,total cholesterol and glycated haemoglobin were higher in the PE group than those in the GDM group and the normal control,and high density lipoprotein(HDL)cholesterol was lower than that in the GDM group and the normal control group(P＜0.05).Vitamin A,vitamin E,vitamin D and folic acid levels were lower in the severe PE group than those in the mild to moderate PE group(P＜0.05).Higher levels of vitamin A,vitamin E,vitamin D and folate were protective factors for GDM patients with severe PE.Folic acid showed higher predictive efficacy and specificity in single indicator analysis.Vitamin A showed high predictive specificity.The combined prediction of four indicators for severe PE in GDM patients was more effective than each individual indicator.Conclusion Serum vitamin A,E,D and folate levels are significantly lower in patients with GDM complicated with PE,and the combination of all four may improve the predictive value of severe PE complicated with GDM.

Objective:To observe and analyze the clinical characteristics of children who died of intraocular retinoblastoma (RB).Methods:A retrospective clinical study. Fourteen children (23 eyes) with intraocular RB who died after receiving treatment in Beijing Children's Hospital from 2009 to 2017 were included in the study. Among the children, there were 7 males (10 eyes) and 7 females (13 eyes); 5 had unilateral and 9 had bilateral tumor. Age were 17.2±15.5 months. All children underwent RetCam examination. RB was staged according to the international intraocular RB classify. Among the 23 eyes, 1 eye was in stage B, 2 eyes were in stage C, 12 eyes in stage D, and 8 eyes in stage E. Treatment methods included a systemic (vincristine, etoposide and carboplatin) chemotherapy (VEC chemotherapy), enucleation surgery, and vitrectomy. The basic conditions including age, time of diagnosis, pathological diagnosis, treatment and main causes of death were retrospectively analyzed.Results:Among the 14 cases, the first symptom was leukemia in 12 cases, red eye in 1 case, and squintin in 1 case. Systemic VEC chemotherapy was used for 1-6 courses of treatment; 5 cases were enucleated, 3 cases underwent histopathological examination; 3 cases were treated with vitrectomy. Among the 3 cases who underwent histopathological examination, the sclera and optic nerve, optic nerve and optic disc were invasted respectively. Seven patients died of tumor metastasis and/or intracranial lesions (50.0%, 7/14); the median survival time was 19 months. Four patients died of treatment (28.6%, 4/14), including 3 patients died of chemotherapy-related side effects, and 1 died of organ failure after enucleation surgery (7.1%); the median survival time was 3.5 months. Early abandonment of treatment died in 3 cases (21.4%, 3/14); the median survival time was 15 months.Conclusion:Intracranial metastasis is the main cause of death in children with intraocular RB.

A classical Monteggia fracture is defined as an ulnar fracture with dislocation of the proximal radioulnar joints. If combined with posterior dislocation of the radial head (posterior dislocation of the radiocapitellar joints), it is called a posterior Monteggia fracture. And for those without dislocation of the proximal radioulnar joints, it should not be defined as the posterior Monteggia fracture, but as the posterior dislocation of the proximal ulna fracture. For dislocation of the proximal radioulnar joints, the Monteggia fractures, clinical are relatively rare. The coronoid process fracture is comminuted, the proximal radioulnar joints are destroyed, the membrane and the annular ligament is injured. After restoring osseous structure and repairing the lateral ligament complex, we must also pay attention to the stability of proximal radioulnar joints, and the prognostic efficacy not sure. However, posterior dislocation of proximal ulna fractures is relatively common in clinical practice, and the coronal process fracture is usually complete, with the annular ligament and interosseous membrane intact. In treatment, the bone structure is mainly restored, and the lateral ligament complex of elbow joint is treated at the same time, with good prognosis. Through anatomical basis, imaging characteristics, injury characteristics, treatment and prognosis, we can distinguish with the posterior Monteggia fracture and posterior dislocation of proximal ulna fracture.

Adenocarcinoma of esophagogastric junction (AEG) has attracted more attention in recent years. Surgical method of Siewert type Ⅱ AEG is especially controversial, mainly focusing on the scope of lymph node dissection, safety of surgical margin, and digestive tract reconstruction. The abdominal transhiatal approach and right thoracoabdominal Ivor-Lewis approach are the main surgical approaches of totally laparoscopic or thoracoscopic surgery for Siewert type Ⅱ AEG, which not only need close teamwork, but also require rich experience in laparoscopic surgery. The authors has started to choose these two totally minimally invasive surgical approaches, the feasibility and safety of which are proved. The key surgical details are presented in this article for reference.
