Objective To observe the characteristics of images of optic coherence tomography (OCT) for the macular region of congenital retinoschisis and investigate its significance. Methods The data of OCT of 11 patients (20 eyes) with congenital macular retinoschisis diagnosed by direct or preplaced-mirror ophthalmoscopy, fundus fluorescein angiography (FFA), and electroretinography (ERG) were retrospectively analyzed. Results The images of OCT showed split in the mid portion of sensory retina at the macula in all eyes. The retina of fovea centralis was divided by the split into two slightly thickening layers. In addition, in a few number of cases, the parafoveal sensory retina which became much thickening with 2 splits, was divided into 3 layers. Conclusion The characteristic of images of OCT in macular congenital retinoschisis is the split cavity at the middle layer of the retina, and OCT has a high sensitivity in the diagnosis of congenital retinoschisis.

A novel strain,which could use 2-hydroxypyridine (2HP) as the sole source of carbon,nitrogen,and energy,was isolated from petroleum-contaminated soil at the Liaohe estuarine wetland.Strain 2PR was identified as Arthrobacter based on the morphology and 16S rRNA gene sequence.The optimum growth and degradation condition upon 2PR is 30℃ and pH 7.0,respectively.Under this condition,2HP degradation rate were 97.34％,94.95％,94.48％ and 89.21％ with 2,4,6 and 8 mg/ml initial concentration of 2HP at 42,96,120 and 156 h,respectively.Strain growth and 2HP degradation kinetics studies indicated that the strain followed Logisitic model,which could provide a theoretical and technical reference for the biodegradation of 2HP.The color of strain 2PR culture upon 2HP-MSN changed from colorless to blue,and then turned to brown.The blue pigment,which was observed at the culture of strain 2PR,was identified as 4,5,4',5'-tetrahydroxy-3,3'-diazadiphenoquinone-(2,2') by high performance liquid chromatography (HPLC) and high-performance liquid chromatography-mass spectrometry (LC-MS) analysis.The LC-MS signal with m/z =249.1 was observed in resting cells reaction sample with 2HP as the substrate.The degradation of 2HP might be achieved by a dioxygenase to produce 2,3,6-trihydroxypyridine,which could transformed to the blue pigment spontaneously,and then 2,3,6-trihydroxypyridine was converted with an pyridine-ring cleavage reaction.Among all the reported strains,strain 2PR has the strongest tolerance and the highest 2HP degradation efficiency at present.The strain has a promising application potential for 2HP waste treatment.

BACKGROUND: Although there are many studies on acute patellar dislocation in adolescents, the optimal treatment strategy is under discussion.OBJECTIVE: To summarize the clinical efficacy of reconstruction of the medial patellofemoral ligament (MPFL) in the treatment of adolescent acute patellar dislocation using double-pulley technique.METHODS: Thirty cases of acute patellar dislocation were enrolled and received reconstruction of the MPFL using double-pulley technique. We proceeded to prepare the bone bed for anchor placement at the medial point of the superior edge of the patella and at the upper 1/3 patella along the long axis of the patella using arthroscopic grinding. Two double-loaded 5.0 anchors were respectively placed at the medial point of patella and at the upper 1/3 patella parallel to the patellar articular surface, and then tied using the double-pulley technique. Long longitudinal incisions were performed at the medial condyle and at the adductor tubercle to expose these two structures, the deep fascias tunnel between two incisions were penetrated to pull the tendon weave end through the tunnel until the lateral side along a femoral tunnel; finally the tendon was fixed using screws in appropriate tightness. All patients were followed for more than 10 months, and the patellar-related parameters and knee function parameters were compared before and after operation. RESULTS AND CONCLUSION: There were 12 cases of intra-articular cartilage injury and 4 cases of meniscus injury. The patella title angle, Q-angle and outward shift distance at the last follow-up were less than those before operation. Lysholm and International Knee Documentation Committee scores at the last follow-up were higher than those before operation. The mean operation time was (90±10.5) minutes. There was one patient with knee movement angle from 0° to 30° and one patient with a patellar fracture caused by slipping and treated with internal fixation. None of patients appeared with patellar dislocation, positive apprehension test infection or poor wound healing. These results indicate that the simple and mini-invasive double-pulley technique is a good treatment strategy for acute patellar dislocation, because it is consistent with patellar anatomical stability, holds patellar trajectory visibility, quick recovery and good curative effect. Additionally, osteotomy is recommended when the simple efficacy is not satisfactory.

Viperin is an endoplasmic reticulum (ER)-associated protein that has been identified as an innate antiviral protein. Viperin expression can be largely upregulated by viruses, interferons, and oligonucleotides such as poly I:C and lipopolysaccharides. Viperin inhibits viral replication by interactiing with host cell proteins and several viral proteins, and disrupting the cell membrane system. It shows a broad-spectrum of antiviral activity. Some viruses have developed activities that counteract the action of viperin during a long- term period of evolution with hosts by impairing viperin expression. In addition to its antiviral effects, viperin has several other biological functions. This article review the basic characteristics of viperin and the state of current research into its antiviral effects, demonstrating the rapid progress that has been made in this field.
