[Characteristics and Source of VOCs During O Pollution Between August to September, Langfang Development Zones].

A total of 99 volatile organic compound(VOC) species were detected the Langfang development zones based on continuous monitoring using a ZF-PKU-1007 between August 25 and September 30, 2018. The concentrations, reactivity, and sources of VOCs were studied under different O concentrations using compositional analysis. The results showed that the average VOCs concentration during the research period was(75.

Traumatic macular hole study: a multicenter comparative study between immediate vitrectomy and six-month observation for spontaneous closure.

Background: Closure of traumatic macular hole (TMH) can be achieved spontaneously or by surgical intervention. Thus far, there exist no prospective comparative studies that have analyzed the difference between the two modalities. This study aimed to compare the anatomical and visual recovery of eyes with TMH following either an immediate vitrectomy or six-month observation.

Glucocorticoid treatment inhibits intracerebral hemorrhage‑induced inflammation by targeting the microRNA‑155/SOCS‑1 signaling pathway.

Intracerebral hemorrhage (ICH) results in inflammation, and glucocorticoids have been proven to be effective inhibitors of ICH‑induced inflammation. However, the precise underlying mechanisms of ICH‑induced inflammation and glucocorticoid function remain largely undefined. Using a mouse ICH model, the present study demonstrated that the short non‑coding RNA molecule microRNA‑155 (miR‑155) is involved in the inflammatory process initiated by ICH in mice.

Multimodal Imaging Evaluations of Focal Choroidal Excavations in Eyes with Central Serous Chorioretinopathy.

Purpose. To investigate the prevalence and characteristics of focal choroidal excavation (FCE) concurrent with central serous chorioretinopathy (CSC) using multimodal imaging. Methods.

Co-existent choroidal neovascular membrane and macular hole in pathologic myopia: a long follow-up clinical outcome and literature review.

Choroidal neovascularization (CNV) is an uncommon complication associated with a macular hole. In this case report of a rare condition, we present a pathologic myopia patient with a co-existent macular hole and choroidal neovascular membrane. The patient was treated with photodynamic therapy for CNV, and then vitreous surgery for the retinal detachment and macular hole.

Identification of a novel frameshift mutation in PITX2 gene in a Chinese family with Axenfeld-Rieger syndrome.

Objective: Axenfeld-Rieger syndrome (ARS) is phenotypically and genetically heterogeneous. In this study, we identified the underlying genetic defect in a Chinese family with ARS.

Methods: A detailed family history and clinical data were recorded.

[Evaluation of photodynamic therapy in idiopathic choroidal neovascularization].

Objective: To evaluate the effectiveness of photodynamic therapy (PDT) in the treatment of idiopathic choroidal neovascularization (CNV).

Methods: Sixty-one cases (61 eyes) of CNV were treated with PDT and the fundus appearance, visual acuity, retina thickness as well as the fundus angiographic imaging were observed before and after the therapy. PDT was performed 1.

Adenoma of nonpigmented epithelium in ciliary body: literature review and case report.

Adenomas of the nonpigmented ciliary epithelium (NPCE) are often clinically indistinguishable from amelanotic malignant melanomas of the ciliary body or metastatic carcinomas. This paper reports a case study of a distinctive variant of adenoma of the NPCE, which clinically appears as epiretinal membrane in the macular region. Histopathologic studies have revealed this is an adenoma of the NPCE.

[Establishment of a mouse model of primary biliary cirrhosis by AMA M2 autoantigen injection].

Objectives: To establish a primary biliary cirrhosis (PBC) model by AMAM2 autoantigen injection into C57BL/6 mice.

Methods: Mice of the model group were immunized intraperitonealy with 200 microl of purified recombinant AMAM2 autoantigen in complete Freund's adjuvant (CFA). Mice immunized with bovine serum albumin and CFA in the same way were used as negative controls.

Development of an enzyme immune assay for detecting M2 autoantibodies specific for primary biliary cirrhosis.

Objective: To develope a new enzyme immune assay (ELISA) for detection of M2 antibody specific for primary biliary cirrhosis (PBC) by using a triple hybrid clone as antigen, which coexpresses the three immunodominant lipoyl domains of PDC-E2, BCOADC-E2 and OGDC-E2 from human sources.

Methods: After expressing autoantigens of PBC in prokaryote by constructing recombinant expressive plasmid successfully, the fusion protein was purified by affinity chromatography. The sera of 17 PBC patients were examined.
