Digitalizing Self-Assembled Chiral Superstructures for Optical Vortex Processing.

Cholesteric liquid crystal (CLC) chiral superstructures exhibit unique features; that is, polychromatic and spin-determined phase modulation. Here, a concept for digitalized chiral superstructures is proposed, which further enables the arbitrary manipulation of reflective geometric phase and may significantly upgrade existing optical apparatus. By encoding a specifically designed binary pattern, an innovative CLC optical vortex (OV) processor is demonstrated.

Muscone exerts protective roles on alcohol-induced osteonecrosis of the femoral head.

Long-term alcohol abuse causes musculoskeletal disorders, among of which, alcohol-induced osteonecrosis of the femoral head (ONFH) is of concern due to its significant and severe complications. A variety of methods have been attempted to prevent alcohol-induced ONFH, and monomers extracted from Chinese herbs might benefit the disease profoundly. In the current study, muscone, the main ingredient of musk, was used to prevent alcohol-induced ONFH.

Light-Patterned Crystallographic Direction of a Self-Organized 3D Soft Photonic Crystal.

Uniform and patterned orientation of a crystallographic direction of ordered materials is of fundamental significance and of great interest for electronic and photonic applications. However, such orientation control is generally complicated and challenging with regard to inorganic and organic crystalline materials due to the occurrence of uncontrollable dislocations or defects. Achieving uniform lattice orientation in frustrated liquid-crystalline phases, like cubic blue phases, is a formidable task.

Light-Driven Rotation and Pitch Tuning of Self-Organized Cholesteric Gratings Formed in a Semi-Free Film.

Cholesteric liquid crystal (CLC) has attracted intensive attention due to its ability to form a periodic helical structure with broad tunability. CLC gratings in open systems are especially promising in sensing and micromanipulation. However, there is still much to learn about the inherent mechanism of such gratings.

Smectic Layer Origami via Preprogrammed Photoalignment.

Hierarchical architecture is of vital importance in soft materials. Focal conic domains (FCDs) of smectic liquid crystals, characterized by an ordered lamellar structure, attract intensive attention. Simultaneously tailoring the geometry and clustering characteristics of FCDs remains a challenge.

Integrated and reconfigurable optical paths based on stacking optical functional films.

A strategy for integrated and reconfigurable optical paths based on stacking optical functional films is proposed. It is demonstrated by stacking two liquid crystal polymer q-plates and one quarter-wave plate for vector vortex beams generation. The topological charge and polarization order of generated vector vortex beams can be controlled independently by stacking and reordering different optical films with repeated adhesive ability.

Extra-articular distal tibia facture (AO-43A): A retrospective study comparing modified MIPPO with IMN.

Purpose: We introduce a new MIPPO procedure which is simple and effective for the treatment of extra-articular distal tibia facture (AO-43A). The aim of this retrospective study was to compare our modified MIPPO with IMN.

Materials And Methods: This retrospective study included 64 patients treated with our modified MIPPO and 61 patients with IMN.

Late surgery for acetabular fractures in a Chinese level I trauma centre: surgical experience and outcomes.

Purpose: Delayed surgical management of acetabular fractures, often necessary due to life-threatening concomitant injuries, is a great challenge because delays may potentially increase complications and decrease outcomes. We report clinical outcomes of 61 acetabular fractures treated by delayed open reduction and internal fixation (ORIF) with an injury-to-surgery interval (ISI) of 22-399 days.

Methods: Operations were performed between April 2001 and December 2008.

[Spectrum-effect relationship of Moutan cortex against lipopolysaccharide-induced acute lung injury].

This research is to study the relationship between HPLC fingerprints of Moutan Cortex, Paeoniae Radix Rubra and Paeoniae Radix Alba and their activity on lipopolysaccharide-induced acute lung injury. HPLC fingerprints of each extract of Moutan Cortex,Paeoniae Radix Rubra and Paeoniae Radix Alba were established by an optimized HPLC-MS method. The activities of all samples against protein and tumor necrosis a factor were tested by the model of lipopolysaccharide-induced acute lung injury.

Association of the CTLA-4 +49A/G polymorphism with rheumatoid arthritis in Chinese Han population.

Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is an important molecule in the regulation of T cells, so the CTLA-4 gene has been considered as a strong candidate associated with T cell-mediated autoimmune diseases such as rheumatoid arthritis (RA). CTLA-4 has many variants and polymorphic forms, among which the +49A/G polymorphism, causing a non-synonymous substitution, has been studied most. However, previous studies of the association between the +49A/G polymorphism of the CTLA-4 gene and RA have provided conflicting results.

Minimally invasive percutaneous osteosynthesis for proximal humeral shaft fractures with the PHILOS through the deltopectoral approach.

Purpose: The aim of this study was to evaluate clinical outcomes and complications following minimally invasive plate osteosynthesis (MIPO) with the proximal humeral internal locking system (PHILOS) for treating proximal humeral shaft fracture through the deltopectoral approach.

Methods: Between November 2008 and March 2010, 74 patients with unilateral proximal humeral shaft fractures were treated using the MIPO technique with the PHILOS through the deltopectoral approach. Patients received an average follow-up of 16.

[Study of simplification of prediction model for kiwifruit firmness using near infrared spectroscopy].

To simplify the prediction model of kiwifruit firmness, SNV was used to preprocess the near infrared (NIR) spectra (1 000-2 500 nm)of kiwifruit. PLS model simplification by optimizing spectral intervals and decreasing the number of factors through net analyte preprocessing (NAP)was carried out. Results showed that the performance of NAP/PLS model is the best.

 Autologous Platelet-rich Plasma Enhances Healing of Chronic Wounds.

Chronic wounds are a frequent problem in developing countries, are often difficult to heal because they lack the necessary growth factors to maintain the healing process, and are frequently complicated by superinfection. Conventional therapies such as dressings, surgical debridement, and even skin grafting cannot provide satisfactory healing since these treatments are not able to provide enough necessary growth factors to modulate the healing process. Platelet-rich plasma (PRP), as a concentrate of platelets, releases a high concentration of multiple growth factors that can modulate healing processes.
