The inability of current catheter ablation procedures to accurately monitor lesion formation limits their safety and efficacy. An advanced fully integrated radiofrequency (RF)/optical coherence tomography (OCT) ablation catheter is developed, which enables real-time monitoring during ablation. An OCT fiber array is especially designed, developed and integrated into an off-the-shelf irrigated RF ablation catheter. In-vitro experimental studies performed on poultry and ovine hearts demonstrate the ability of the integrated RF/OCT system to provide information on the quality and orientation of catheter/wall contact. Experimental results show that adipose tissue can be accurately identified from normal myocardial tissue with 94% accuracy and lesion formation is monitored with an overall accuracy of 93%. The ability to predict pop events is also demonstrated, with an accuracy of 86%.Anatase TiO2 with co-exposed (001) and (101) surfaces [(001)-(101)-TiO2 ], as a semiconductor photocatalyst in crystal plane control engineering, has become a research hotspot in environmental purification and energy conversion due to its strong physicochemical stability, non-toxic and harmless, and low production cost. This review briefly introduces the basic principles and influencing factors of [(001)-(101)-TiO2 ]. On this basis, the effect of heterostructures formed by different materials and modification methods on its photocatalytic activity are elaborated in detail. Mainly formed heterostructures mentioned in this review include oxygen vacancy/Ti3+ -[(001)-(101)-TiO2 ] heterostructures, noble metal-[(001)-(101)-TiO2 ] heterostructures, metal sulfide-[(001)-(101)-TiO2 ] heterostructures, metal oxide-[(001)-(101)-TiO2 ] heterostructures and carbon material-[(001)-(101)-TiO2 ] heterostructures. The light absorption range and charge separation mechanism of (001)-(101)-TiO2 after modification are discussed. Moreover, the application of photocatalytic redox reaction in simulating photosynthesis to prepare new energy (hydrogen evolution and CO2 reduction), environmental purification and sterilization is introduced in detail. Finally, various measures of designing (001)-(101)-TiO2 nanostructures for further applications in energy production and environmental remediation are discussed. Acupuncture is commonly used in Traditional Chinese Medicine for treatment of diabetic peripheral neuropathy (DPN), but data from randomized controlled trials are rare. This randomized, placebo-controlled, partially double-blinded clinical trial randomly assigned adults with confirmed type 2 diabetes-induced DPN to receive 10 sessions of needle acupuncture, laser acupuncture, or placebo laser acupuncture for 10 consecutive weeks. Treatment was provided at bilateral acupoints Ex-LE-10 (Bafeng), Ex-LE-12 (Qiduan), and ST-34 (Lianqiu). Neurological assessments, including nerve conduction studies (NCS) of sural and tibial nerves, were performed at baseline and weeks 6 and 15. Primary outcome was delta of sural sensory nerve action potential (SNAP). Secondary outcomes included further NCS values, clinical scores, and patient-reported outcome measures (PROMs). Of 180 participants, 172 completed the study. Sural SNAP and sural and tibial nerve conduction velocities improved significantly after 10 treatments when comparing needle acupuncture to placebo. Needle acupuncture showed earlier onset of action than laser acupuncture. PROMs showed larger improvements following needle and laser acupuncture than placebo, reaching significant differences for hyperesthesia and cramps following needle acupuncture and for heat sensation following laser acupuncture. Classical needle acupuncture had significant effects on DPN. Improvement in NCS values presumably indicates structural neuroregeneration following acupuncture.
